+
+	* s/aix3-2.h (LIBS_SYSTEM): Put -LIM -Liconv here.
+
+	* systty.h (HAVE_LTCHARS, HAVE_TCHARS): New macros; define them if

+
+	* xfns.c: Clear out the old face stuff.

+	Fx_set_face, Fx_get_face): Removed.
+	(syms_of_xfns): Remove defsubr for Fx_set_face.
+
+	Arrange for font names to get fully resolved - no wildcards.
+	* xfns.c (x_set_frame_parameters): Store the value in the frame
+	parameter alist before we call the setter function, so the setter
+	function can touch up the value if it chooses.
+	(x_set_foreground_color, x_set_background_color): Call
+	recompute_basic_faces, so their GC's will reflect the changes.
+	(x_new_font): Add extern declaration - this returns a Lisp_Object
+	now, the fully resolved font name.
+	(x_set_font): Accept the fully resolved name from x_new_font, and
+	put it in the frame's parameter alist.  Call recompute_basic_faces.
+	* xterm.c (x_new_font): Return the fully resolved font name, Qnil
+	(if no match), or Qt (match, but unacceptable metrics).
+	* xterm.c (x_new_font): Don't call init_frame_faces.
+
+	* xterm.h: New section for declarations for xfaces.c.
+	(init_frame_faces, free_frame_faces, intern_face,
+	face_name_id_number, same_size_fonts, recompute_basic_faces,
+	compute_char_face, compute_glyph_face): Declare these here.
+	* xfaces.c (same_size_fonts): We can now remove this extern
+	declaration.
+	* xfns.c (face_name_id_number): Likewise.

+
+	* xterm.c (dumpglyphs): Remember that the default faces can have
+	null fonts, too.
+
+	* xfns.c (Fx_list_fonts): Remember that FACE may not have a font
+	specified.  Don't specify 30000 as the maximum limit on the number
+	of fontns returned  - 2000 is more reasonable. 
+
+	* xfaces.c (build_face, unload_font, free_frame_faces): Don't
+	forget to block input while making X calls.
+
+	Treat faces as structures specifying modifications to the frame's
+	parameters, rather than things which need to specify a complete
+	set of parameters by themselves.
+	* xfaces.c (init_frame_faces): Don't set up the two frame display
+	faces by querying the GC - just leave all their fields blank, and
+	call recompute_basic_faces, letting build_face do the work of
+	consulting the frame when necessary.
+	(recompute_basic_faces): New function.
+	(compute_base_faces): New function for obtaining the "identity"
+	for compute_char_face and compute_glyph_face.
+	(compute_char_face, compute_glyph_face): Call it, instead of copying
+	FRAME_DEFAULT_FACE.
+	* xfns.c (x_make_gc): No need to call init_frame_faces here.
+
+	* xfaces.c (intern_frame_face): This can be static.
+
+	* dispextern.h (struct face): New field - `copy', to help us with
+	resource allocation.
+	* xfaces.c (free_frame_faces): Do free the first two faces; don't
+	free anything from a face that's a copy.
+	(intern_frame_face): Mark every face we intern as a copy; its
+	resources are actually a combination of the real faces.
+	(Fset_face_attribute_internal): No need to check if we're trying
+	to free one of the frame's GC's; they never enter into the
+	picture.
+
+	* casetab.c: Fix formatting, so as not to confuse etags.
+
+	* xfns.c (Fx_list_fonts): New function.
+	(face_name_id_number): Add extern declaration for this.
+	* xfaces.c (face_name_id_number): Make this externally visible,
+	and make the FRAME argument a FRAME_PTR, not a Lisp_Object.
+	(compute_char_face): Call face_name_id_number properly.
+
+	* xfaces.c (unload_color): Don't free the pixel for now.
+
+	* xfaces.c (merge_faces): You can't tell if a font is a
+	character-cell font or not by testing whether or not it has a
+	per_char table.  They all do.
+	* xterm.c (x_new_font): Same deal.
+	* xfns.c (Fx_list_fonts): Same deal.
+
+	* m/iris4d.h: Dyke out the section which specifies how to get the
+	load average.
+
+	* paths.h (PATH_INFO): New path, to edited by the configuration
+	process.
+	* callproc.c (Vconfigure_info_directory): New variable, used
+	internally by build process.
+	(syms_of_callproc): DEFVAR it and initialize it.
+
+	* keyboard.c (Fcurrent_input_mode): Use XFASTINT to build the last
+	element of the return value, not XSETINT.
+
+1993-05-24  Jim Blandy  (jimb@wookumz.gnu.ai.mit.edu)
+
+	Changes for OSF/1:
+	* mem-limits.h [__osf__ && (__mips || mips)]: #include
+	<sys/time.h> and <sys/resource.h>.
+	(get_lim_data): OSF wants a definition like BSD4_2's.
+	* s/osf1.h: #include "bsd4-3.h", not "s-bsd4-3.h".
+
+	* ymakefile (LIBX): Put LD_SWITCH_X_SITE before the libraries, so
+	it actually has an effect.
+
+	Some makes can't handle form feed characters in their makefiles.
+	* s/usg5-3.h: Remove form feed.
+	* s/template.h, m/template.h: Remove form feeds.
+
+	* xfns.c (select_visual): Include the screen number in the

+	the right buffer.
+
+1993-05-24  Richard Stallman  (rms@mole.gnu.ai.mit.edu)
+
+	* keyboard.c (modify_event_symbol): If a name_table elt is null,
+	generate a name to use.  Don't crash.
+

+
+	* xterm.c (XTread_socket): For ConfigureNotify event,

+	don't support them yet.
+	* xfns.c (x_set_font): Report the error message properly.
+
+	* xfns.c (Fx_parse_geometry): No need to call check_x here; it
+	doesn't interact with the server at all, and we need it in order
+	to create our first frame.
+
+1993-05-24  Richard Stallman  (rms@mole.gnu.ai.mit.edu)
+
+	* s/linux.h (HAVE_SETSID): Defined.

+
+	* syssignal.h (sys_signal): Declare the second argument to have

+
+	* xfaces.c (Fset_face_attribute_internal): Don't call unload_font

+	* m/iris4d.h (NEED_SIOCTL): Move this to...
+	* s/irix3-3.h (NEED_SIOCTL): ... here; apparently it's not
+	necessary in irix4-0.h.

+	already declares this elsewhere.
+	(PTY_TTY_NAME_SPRINTF): #undef this before re-#defining it.
+	* m/ibmps2-aix.h, m/pfa50.h, s/hpux.h, s/isc2-2.h, s/linux.h,

+
+	* config.h.in (LD_SWITCH_X_SITE, C_SWITCH_X_SITE): Change the
+	#defines to #undef's, so ../configure knows it should tweak them.

+	changes.

+	Potorti` <pot@fly.CNUCE.CNR.IT> says it's necessary on his

+
+1993-05-21  Richard Stallman  (rms@mole.gnu.ai.mit.edu)
+
+	* sysdep.c (wait_for_termination): Copy code from 18.59

+1993-05-19  Jim Blandy  (jimb@wookumz.gnu.ai.mit.edu)
+
+	Some time-handling patches from Paul Eggert:
+	* editfns.c (Fcurrent_time_zone): Take an optional argument specifying

+
+	Some more changes from Michael K. Johnson for Linux.
+	* s/template.h: Mention that you should #define HAVE_TERMIO or
+	HAVE_TERMIOS, but not both, and that HAVE_TERMIOS is preferred.
+	* systty.h (EMACS_SET_TTY_PGRP): Don't assign the return value of
+	tcsetpgrp to *pgid; it's just a status value.
+	* config.h.in (HAVE_RANDOM): This shouldn't be defined on Linux
+	systems using XFree386, and perhaps is inappropriate in general.
+	* m/intel386.h: #undefine the integer size macros, since the Linux
+	<values.h> file #defines them itself.
+	* mem-limits.h (get_lim_data): Linux has the ulimit call; if it
+	fails, fall back on ULIMIT_BREAK_VALUE.
+	* process.c: Linux needs the WAITTYPE, etc. definitions.
+	* unexec.c (hdr, ohdr): Linux has the ordinary `struct exec' type;
+	no need to use SYSV names.
+	* s/linux.h: New file.
+
+	Some changes from Michael K. Johnson for Linux.
+	* sysdep.c (sys_siglist): Don't define this if HAVE_SYS_SIGLIST is

+	given us a definition already.
+	* syssignal.h (sys_sigpause): Fix argument in prototype.
+	* sysdep.c (init_signals): The masks are called empty_mask and
+	full_mask, not signal_empty_mask and signal_full_mask.

+	* systty.h (EMACS_SET_TTY_PGRP): Call tcsetpgrp with the correct

+	* fileio.c (Ffind_file_name_handler): Check that FILENAME is a
+	string.
+
+	* process.c (wait_reading_process_input): Undo change of April
+	29th, since that re-introduces the race condition the comments are

+	status_notify, though.
+
+	* process.c (wait_reading_process_input): Don't forget to call
+	clear_waiting_for_input when we exit the loop because process
+	input has arrived.

+
+1993-05-18  Jim Blandy  (jimb@wookumz.gnu.ai.mit.edu)
+
+	* xdisp.c (display_text_line): If the newline (or C-m, in
+	selective-display) has a non-default face, apply that face to the
+	remainder of the line, so that the fill occupies the entire line.
+
+	* xterm.c (x_new_font): Tell the frame display faces about the
+	newly chosen font.
+
+	Make sure that all the display faces use fonts of the
+	same dimensions as the default face, so as not to confuse the rest
+	of the redisplay code.
+	* xfaces.c (same_size_fonts): New function.

+	* keyboard.c (make_lispy_event): Controlify here.
+
+1993-05-17  Jim Blandy  (jimb@totoro.cs.oberlin.edu)
+
+	* xdisp.c (redisplay_window): Make the scrollbar reflect the
+	extent of the visible region, not the whole buffer.
+
+	* xfaces.c (free_frame_faces): Don't free the resources from the
+	first two faces.
+
+	* lisp.h (malloc, realloc): Declare these to return void *, to
+	avoid conflicts with ANSI header files.

+	* sysdep.c (reset_sys_modes): Test the return value of
+	EMACS_SET_TTY properly.
+	* systty.h (EMACS_GET_TTY, EMACS_SET_TTY): Document the return
+	values.

+
+	* config.h.in (STDC_HEADERS, TIME_WITH_SYS_TIME,
+	CRAY_STACKSEG_END, STACK_DIRECTION): Add #undef clauses for these,
+	since otherwise the autoconf tests in configure.in won't do us
+	much good.
+
+1993-05-16  Richard Stallman  (rms@mole.gnu.ai.mit.edu)
+
+	* buffer.c (overlays_at): New arg EXTEND.
+	(Foverlays_at, Fnext_overlay_change): Pass 1.

+	Set up Qcurrent_load_list.
+	(readevalloop): Specbind Qcurrent_load_list instead of ad-hoc saving.

+
+1993-05-15  Jim Blandy  (jimb@geech.gnu.ai.mit.edu)
+
+	* xfaces.c (Fset_face_attribute_internal): Jolt redisplay, so it
+	knows something has changed.
+
+	* xfaces.c (unload_color): Don't try to unload the standard black
+	or white pixel.
+
+	More changes from David Mackenzie.
+	* ymakefile (emacs): No need to edit srcdir into a lisp file and

+	* Makefile.in (srcdir, VPATH): Get this value from the top-level

+	* ymakefile (srcdir, VPATH): New definitions for the Makefile
+	to edit.
+	(ALL_CFLAGS): Remove `-Is' and `-Im'; add `-I${srcdir}', and
+	`-I.'.
+	(emacs): Adjust dumping commands to deal with a separate source
+	directory.
+	(${etc}DOC): Pass `-d ${srcdir}' to make-docfile, to tell it where
+	to find the source files.
+	(prefix-args): Find the source code in ${srcdir}.
+
+	* process.c (wait_reading_process_input): If we're running
+	Solaris, it's not necessary to check if we should redeliver SIGIO,
+	according to David Mackenzie.
+	* s/sol2.h: #include "usg5-4.h", and #define const.
+
+	* systime.h: Borrow CPP sequence from getdate.y to include the
+	proper combination of <time.h> and <sys/time.h>.

+	Don't die if SELECTION is not recognized.
+
+	* dispnew.c (direct_output_forward_char): Just give up
+	if region is being highlighted.
+
+	* xdisp.c (redisplay, redisplay_window): Don't use the cursor-motion
+	special-case code if the region is or was highlighted.
+	
+	* xfaces.c (compute_char_face): New args REGION_BEG, REGION_END.
+	Don't sort if noverlays is 0 or 1.
+
+	* dispnew.c (direct_output_for_insert): Pass those args.
+	* xdisp.c (display_text_line): Pass those args,
+	describing the region if the mark is transient and active.
+
+1993-05-14  Jim Blandy  (jimb@geech.gnu.ai.mit.edu)
+
+	* buffer.c (Fmove_overlay): If the overlay is in no buffer and the
+	BUFFER argument has been omitted, put it in the current buffer,
+	for symmetry with move-marker.
+
+	* buffer.c (Fdelete_overlay): Make the overlay's markers point
+	nowhere, not at 1.  Do this after calling redisplay_region, so
+	that code knows what section has changed.
+
+1993-05-14  Richard Stallman  (rms@mole.gnu.ai.mit.edu)
+
+	* xdisp.c (display_menu_bar): Update FRAME_MENU_BAR_ITEMS here.

+	* buffer.c (Foverlay_start, Foverlay_end, Foverlay_buffer,
+	Foverlay_properties): Functions moved here from subr.el.

+1993-05-13  Jim Blandy  (jimb@totoro.cs.oberlin.edu)
+
+	* xfaces.c (compute_char_face): When merging the overlays,
+	traverse sortvec, not overlay_vec; the latter isn't the one we
+	sorted.
+
+	* xterm.c (dumpglyphs): Give the cursor higher priority than the
+	face specified by the glyph under it.
+
+	* xterm.c (dumpglyphs): Move the underline up a row.  I dislike
+	the way X addresses pixels.  Quickdraw is much nicer.
+
+	* xfaces.c (intern_face): If the face has a GC, but it's not the
+	default or modeline face, abort.  Nothing but those two faces
+	should have a GC *and* be passed to intern_face.
+	(compute_char_face, compute_glyph_face): After copying
+	the frame's default face into face, to use as a base case for
+	calculation, set the `gc' member to zero; that way we don't have
+	things lying around that look like display faces but aren't.
+
+	* xfaces.c (intern_frame_face): When copying the new face into the
+	frame's face array, remember that the number of bytes to copy is
+	sizeof (*new_face), not sizeof (new_face).
+
+	* xfaces.c (compute_char_face): Assume that W is displaying the
+	current buffer.  Abort if it isn't.
+
+	* lisp.h (Lisp_Overlay): New tag.
+	(OVERLAYP): New predicate.
+	(CHECK_OVERLAY): New type-checker.
+	(Qoverlayp): New extern declaration.
+	* buffer.c (Foverlayp): New function.
+	(Qoverlayp): New atom.
+	(overlays_at, recenter_overlay_lists): Abort if we encounter an
+	invalid overlay.
+	(syms_of_buffer): defsubr Soverlayp; initialize Qoverlayp.
+	(Fdelete_overlay): Set the overlay's markers to point nowhere.
+	Use CHECK_OVERLAY instead of signalling a special error.
+	(Fmove_overlay, Foverlay_put): Use CHECK_OVERLAY instead of
+	signalling a special error.
+	(Foverlay_get): Use CHECK_OVERLAY.
+	* fns.c (internal_equal): Define this for overlays.
+	* buffer.h (OVERLAY_VALID): Define in terms of OVERLAYP.
+	* print.c (print): Give overlays their own print syntax.
+	* alloc.c (mark_object): Treat overlays like conses.
+
+	* lisp.h (FLOATP): Define this appropriately when LISP_FLOAT_TYPE
+	is not defined.
+
+	* buffer.c (Foverlay_get): Return Qnil if the requested property
+	is missing from the property list.
+
+        The text property routines can now modify buffers other
+	than the current one.
+	* insdel.c (modify_region): New argument BUFFER.  Select that
+	buffer while we prepare for the modification, and switch back when
+	we're done.
+	* textprop.c (add_properties, remove_properties): Pass
+	the buffer being modified as the first argument to modify_region.
+	* editfns.c (Fsubst_char_in_region, Ftranslate_region): Pass the
+	current_buffer as the first argument to modify_region.
+	* casefiddle.c (casify_region): Same.
+
+	* dispnew.c (direct_output_for_insert): Compute the face of the
+	character we're inserting properly.
+
+	* xterm.c (dumpglyphs): Pass the proper arguments to intern_face.
+
+	* xterm.c (dumpglyphs): Don't increment left twice.
+
+	* intervals.c (set_point): Check for point out of bounds before
+	checking for an empty interval tree. 
+
+	* cmds.c (Fforward_char): Check proposed new position, and then
+	set point, instead of setting point to a potentially invalid
+	position.
+
+	* lread.c, data.c: If STDC_HEADERS is #defined, include <stdlib.h>
+	to get the extern declarations for atof.  That's where it is in
+	POSIX.
+
+1993-05-12  Jim Blandy  (jimb@geech.gnu.ai.mit.edu)
+
+        * ymakefile (xfaces.o): Add window.h to the dependencies.
+
+	* xfaces.c (intern_frame_face): Exchange order of arguments, to
+	make callers correct.
+
+	* xfaces.c (compute_char_face): Notice the next property change
+	location correctly.
+
+	* xfaces.c (face_name_id_number): Return 0 (the default face) if
+	the name is undefined.
+
+	* xfaces.c (Fset_face_attribute_internal): Do nothing unless FRAME
+	is an X frame.
+
+	* xdisp.c (copy_rope, copy_part_of_rope): Add face argument.
+	(display_text_line): Initialize current_face to zero.   Apply it
+	to characters as we write them to the display matrix.
+	(display_string): Pass the new argument to copy_rope.
+
+	* xdisp.c (display_text_line): Handle the locations of face
+	changes properly.
+
+	* textprop.c (Fnext_single_property_change,
+	Fprevious_single_property_change): Pass arguments to textget in
+	the right order.
+
+	* ymakefile (xfns.o): Remove duplication of buffer.h in dependencies.
+
+	* ymakefile ($(OLDXMENU)): Remove extraneous call to `rm'.
+
+1993-05-12  Richard Stallman  (rms@mole.gnu.ai.mit.edu)
+
+	* keymap.c (Faccessible_keymaps): Use whatever size the vector has.
+	(Fwhere_is_internal): Likewise.
+	(describe_vector): Likewise.
+	(current_minor_maps): Call Findirect_function, so symbols
+	can be used in place of actual maps.
+
+	* xdisp.c (display_text_line): Use break; to exit loop at eol.
+	Duplicate the short MAKE_GLYPH loop after the main loop.
+	If no display table, do obey selective_display_ellipses.
+	(copy_part_of_rope): Arg FROM is now Lisp_Object *.
+
+	* xfaces.c: Do include window.h.
+	(compute_char_face): Supply third arg of Fget_text_property.
+
+	* keyboard.c (make_lispy_event): Don't set shift modifier for C-^.
+
+	* callproc.c (child_setup): Omit duplicates from new env array.
+
+1993-05-10  Jim Blandy  (jimb@geech.gnu.ai.mit.edu)
+
+        * fileio.c (ro_fsys) [SOLARIS_BROKEN_ACCESS]: Check for the
+        filesystem being ro, since Solaris 2.1 doesn't.
+        (file-writable-p): Call ro_fsys.
+	* s/sol2.h (SOLARIS_BROKEN_ACCESS): Define this.
+
+	* systime.h: Use the strategy from getdate.y to include the proper
+	combination of <time.h> and <sys/time.h>.
+
+	* xfns.c (Fx_create_frame): Use an XLFD name for the default font,
+	instead of "9x15" or whatever it was.
+
+	* xdisp.c (display_text_line): Make face-handling code conditional
+	on HAVE_X_WINDOWS macro.  Perhaps this isn't the best approach,
+	but it'll do for now.
+
+	* xdisp.c (display_text_line): We can't use the FRAME_DEFAULT_FACE
+	macro here; that's x-specific.  Just don't pass the second
+	argument.
+	* xfaces.c (compute_glyph_face): Remove the BASIC_FACE argument;
+	use F's default face.
+
+1993-05-09  Jim Blandy  (jimb@totoro.cs.oberlin.edu)
+
+	* xfaces.c (Fmake_face_internal): Do nothing for non-X frames.
+
+	* dispextern.h (struct face): Add cached_index member.

+	searches of face_vector.
+
+	* xfaces.c (intern_face): Renamed from get_display_face.
+
+	* xfns.c (x_make_gc): After building the GC's for the frame, call
+	init_frame_faces to set up the first two faces.
+	* xfaces.c (init_frame_faces): Don't just try to copy the default
+	and mode line faces from some other random frame; instead, consult
+	the normal_gc and reverse_gc members of the frame, and build the
+	faces based on their parameters.
+
+	Adjust the face computation functions to return frame face ID's,
+	not pointers to display faces; since we call these functions
+	during display construction, we don't want the display faces yet.
+	* xfaces.c (intern_frame_face): New function.
+	(compute_char_face, compute_glyph_face): Apply intern_frame_face
+	to the computed face, and return the frame face's ID, instead of
+	calling intern_face and returning a pointer to a display frame.
+
+	* xfaces.c: Describe the facial data structures.  It took me a
+	while to figure them out; perhaps this will save someone else the
+	trouble.
+
+	Arrange to tell redisplay about changes in overlays.
+	* xdisp.c (redisplay_region): New function.
+	* buffer.c (Fmove_overlay): Call redisplay_region on the areas the
+	overlay has enclosed or left.
+	(Fdelete_overlay): Call redisplay_region on the area the overlay
+	used to occupy.
+	(Foverlay_put): Call redisplay_region on the area the overlay now
+	occupies; we may have put a face property on it.
+
+	* buffer.c (Fmove_overlay): Doc fix.
+
+	* xdisp.c (redisplay): If we're doing a thorough redisplay (all
+	windows on all frames involved), go ahead and flush the GC cache -
+	call clear_face_vector.
+
+	* xdisp.c (display_text_line): Apply faces to characters
+	according to overlays and text properties; use
+	compute_char_face and compute_glyph_face to figure out what
+	face to use, and where a new face starts.
+	* xterm.c (dumpglyphs): Use the upper bits of the glyphs to decide
+	which frame face to use.  Call GLYPH_FOLLOW_ALIASES to make sure
+	we're implementing the glyph table properly.  If we're not using
+	the default or mode line face, call intern_face to find a display
+	face for the frame face selected by the glyph code.  Implement
+	underlining.  Remove the `font' argument; we have to derive this
+	from the frame and face anyway.  Change all callers.
+	* disptab.h (GLYPH_FOLLOW_ALIASES): New macro.
+
+	* xterm.c (x_destroy_window): Call free_frame_faces.
+
+	The GNU coding standards specify that CFLAGS should be left for
+	users to set.
+	* ymakefile (ALL_CFLAGS): Set this to the long string of
+	compilation switches, not CFLAGS.  Changed all uses.
+	(CFLAGS): Make this default to just -g.
+	(.c.o): Define new default rule, to make sure that the right flags
+	get to the compilations.
+
+1993-05-09  Richard Stallman  (rms@mole.gnu.ai.mit.edu)
+
+	* keyboard.c (read_char): Exit kbd macro if Vexecuting_macro is t.
+
+	* pwd.h: File deleted.
+
+1993-05-08  Jim Blandy  (jimb@totoro.cs.oberlin.edu)
+
+	* s/sunos4shr.h: Apply changes from David J. Mackenzie; this isn't
+	used by any configuration right now, but he's trying to make it
+	work.
+	#include "sunos4-1.h" instead of "bsd4-2.h".
+	(O_NDELAY): Don't define this.
+	(SYSTEM_MALLOC): Don't define this, either.
+	(LD_SWITCH_SYSTEM): Remove the definition for this.
+
+	* Makefile.in (DEFS): Remove this; we have configure build a
+	config.h file directly, instead of having lots of -D flags.
+
+	* Makefile.in (CFLAGS): Don't make this carry DEFS from the
+	configure script; the coding standards say that CFLAGS should be
+	left for the user to tweak.
+
+1993-05-08  Richard Stallman  (rms@mole.gnu.ai.mit.edu)
+
+	* keyboard.c (do_mouse_tracking): Now static.
+
+	* xmenu.c (Fx_popup_menu): Add a vector of prefix keys for the panes.
+	(keymap_panes): Allocate that vector.
+	(single_keymap_panes): Fill in that vector.
+	(xmenu_show): Return a list of events, not just one event.
+
+	* keyboard.c (read_char_menu_prompt): Expect Fx_popup_menu
+	to return a list of events.  Don't lose any of them.
+
+	* xfns.c (Fx_get_mouse_event, Fx_mouse_events): Code deleted.
+	* window.c (Vmouse_event): Var deleted.
+	(syms_of_window): Don't make it a Lisp var.
+
+        * keyboard.c (read_avail_input, Fset_input_mode): Make
+        meta_key a three-value variable to support 8-bit input.
+
+1993-05-07  Jim Blandy  (jimb@totoro.cs.oberlin.edu)
+
+	* ymakefile [__GNUC__ && __GNUC__ > 1] (LIB_GCC): Set this even if
+	LINKER is #defined.
+
+	* ymakefile ($(OLDXMENU)): Remove the link before we re-create it;
+	not all versions of ln have the `-f' flag.  Use the LN_S variable,
+	inherited from src/Makefile.
+
+	* Makefile.in (LN_S): New variable, edited by top Makefile.
+	(SUBMAKEFILE): New variable, containing all flags to pass to
+	recursive makes.
+
+	* config.h.in: Adjust this for use by autoconf's AC_CONFIG_HEADER,
+	instead of AC_OUTPUT.
+
+	* xfaces.c (get_display_face): Use face_eql instead of writing it out.
+
+1993-05-06  Jim Blandy  (jimb@totoro.cs.oberlin.edu)
+
+	* keymap.c (Fwhere_is_internal): If FIRSTONLY is non-nil, avoid
+	returning a non-ascii key sequence unless FIRSTONLY is the symbol
+	`non-ascii'.
+
+	* config.h.in: Remove mention of GLYPH datatype; that shouldn't be
+	a user option.
+	* lisp.h (GLYPH, MAKE_GLYPH, GLYPH_CHAR, GLYPH_FACE): New macros.
+
+1993-05-06  Richard Stallman  (rms@mole.gnu.ai.mit.edu)
+
+	* xfns.c (x_get_arg): Call Fintern, not intern.
+
+	* systime.h [SCO]: Include time.h.
+	* s/sco4.h: New file.
+
+	* ymakefile (LIBXMENU): Delete -loldX.
+
+	* emacs.c (main): Handle -display like -d.
+
+1993-05-05  Jim Blandy  (jimb@totoro.cs.oberlin.edu)
+
+	* s/template.h: Explain the relative significance of the SIGIO and
+	INTERRUPT_INPUT macros.
+
+	* ymakefile (buffer.o, insdel.o): Note that these files also
+	depend on blockinput.h.
+
+	* blockinput.h (UNBLOCK_INPUT): We cannot assume that SIGIO is
+	defined everywhere this file is #included; merge the two
+	definitions for defined (SIGIO) and ! defined (SIGIO) into one,
+	which calls reinvoke_input_signal if interrupt_input_pending is
+	set.
+	* keyboard.c (reinvoke_input_signal): New function.
+
+1993-05-04  Richard Stallman  (rms@mole.gnu.ai.mit.edu)
+

+
+1993-05-04  Jim Blandy  (jimb@geech.gnu.ai.mit.edu)
+
+	* keyboard.c (syms_of_keyboard): Doc fix for
+	extra-keyboard-modifiers.
+
+	* lisp.h (CHAR_ALT, CHAR_SUPER, CHAR_HYPER, CHAR_SHIFT, CHAR_CTL,
+	CHAR_META): Shift these all up one bit, back to where they were.
+
+1993-05-02  Jim Blandy  (jimb@totoro.cs.oberlin.edu)
+
+	* keymap.c (Fdefine_prefix_command): Doc fix.
+
+	* ymakefile (C_DEBUG_SWITCH): Undo April 10 change.
+
+1993-05-01  Richard Stallman  (rms@mole.gnu.ai.mit.edu)

+
+1993-04-30  Jim Blandy  (jimb@totoro.cs.oberlin.edu)

+
+1993-04-29  Jim Blandy  (jimb@totoro.cs.oberlin.edu)
+
+        Implement extra_keyboard_modifiers properly.
+	* keyboard.c (syms_of_keyboard): Doc fix for
+	extra-keyboard-modifiers; use the same modifier bits as we do for
+	characters.
+	(read_char): Apply all the modifiers in extra_keyboard_modifiers
+	to the input characters, so you can get hyper, super, and the rest
+	of the gang.
+	* xterm.c (x_emacs_to_x_modifiers): New function.
+	(x_convert_modifiers): Renamed to x_x_to_emacs_modifiers, for
+	consistency.  Callers changed.
+	(XTread_socket): Apply x_emacs_to_x_modifiers to
+	extra_keyboard_modifiers before setting the state member of the
+	event; this will get all the modifiers on ASCII characters.
+
+	* xterm.c (x_text_icon): Don't call XSetIconName; it should be
+	unnecessary, and perhaps it's killing the icon pixmap.
+
+	* lisp.h (CHAR_ALT, CHAR_SUPER, CHAR_HYPER): New constants, in
+	case we need them.
+	* termhooks.h (alt_modifier, super_modifier, hyper_modifier,
+	shift_modifier, ctrl_modifier, meta_modifier): Define these in
+	terms of the CHAR_mumble macros, to avoid having the same thing
+	defined in two places.
+
+	* keyboard.c (kbd_buffer_get_event): Don't generate switch-frame
+	events if they'd only switch to the frame already selected.  This
+	avoids lots of extra switch-frame events when using a separate
+	minibuffer.
+
+1993-04-29  Richard Stallman  (rms@mole.gnu.ai.mit.edu)
+
+	* keyboard.c (Fthis_command_keys): Doc fix.
+
+	* process.c (wait_reading_process_input): Move the status_notify
+	call before the set_waiting_for_input call.
+
+	* fileio.c (Fexpand_file_name): Undo last change--too risky for now.
+
+	* data.c (Fdefine_function): New function (same code as Fdefalias).
+
+1993-04-28  Eric S. Raymond  (eric@mole.gnu.ai.mit.edu)

+
+1993-04-27  Eric S. Raymond  (eric@mole.gnu.ai.mit.edu)
+
+	* eval.c (un_autoload): Don't try to save old autoload forms when
+	we load something in.  Something about the code now conditioned
+	out by UNLOAD was screwing up ordinary autoloads, notably of
+	picture.el.  When I figure out what, I'll fix and re-enable this
+	code.
+
+1993-04-27  Jim Blandy  (jimb@totoro.cs.oberlin.edu)
+
+	* buffer.c (syms_of_buffer): Doc fix for buffer-display-table.
+
+	* systime.h: Doc fix.
+	(EMACS_SET_USECS): Remember that a `usec' is a microsecond, not a
+	millisecond.  What's three orders of magnitude between friends?
+	* dispnew.c (Fsit_for, Fsleep_for): Remember to multiply the
+	`milliseconds' argument by 1000 to get microseconds.
+
+1993-04-26  Roland McGrath  (roland@geech.gnu.ai.mit.edu)
+
+	* fileio.c (Fexpand_file_name):
+	Don't remove trailing / from NEWDIR if just "/".
+
+1993-04-26  Jim Blandy  (jimb@totoro.cs.oberlin.edu)

+	configure script.
+	* s/hpux.h, s/irix3-3.h, s/aix3-1.h (HAVE_GETHOSTNAME): Removed;
+	derived by configure script.
+
+	Arrange for Fy_or_n_p to put off switch-frame events.
+	* lread.c (read_filtered_char): New function, which contains the
+	code which used to be in Fread_char, Fread_event, and
+	Fread_char_exclusive; there was a lot of common code.
+	(Fread_char, Fread_event, Fread_char_exclusive): Rewrite in terms
+	of read_filtered_char.
+	* lisp.h (read_filtered_char): Declare this extern here.
+	* fns.c (Fy_or_n_p): Call read_filtered_char, arranging to delay
+	switch-frame events.
+
+	* keyboard.c (read_key_sequence): Let the `modifiers' variable in
+	the code which deals with KEY being unbound be an int, not a
+	Lisp_Object.
+
+	* config.h.in (getenv): Don't test THIS_IS_YMAKEFILE to see if we
+	should exclude the getenv declaration; instead, test NOT_C_CODE.
+	Per suggestion from Francesco Potorti`.
+	* ymakefile (NOT_C_CODE): Define this; it's true, and useful.
+
+	* dispnew.c (Fsleep_for, Fsit_for): Allow SECONDS to be a
+	floating point value.
+
+1993-04-26  Eric S. Raymond  (eric@mole.gnu.ai.mit.edu)
+
+	* sysdep.c (read_pending_input):
+	Fix the garbaged-modifiers bug under System Vs previous
+	to r4.
+
+1993-04-25  Jim Blandy  (jimb@totoro.cs.oberlin.edu)
+
+	* systty.h (EMACS_GET_TTY, EMACS_SET_TTY): Move these into
+	functions in sysdep.c.
+	* sysdep.c (emacs_get_tty, emacs_set_tty): Here they are.
+
+	* sysdep.c (emacs_set_tty): Call tcsetattr over and over again
+	until it does all of what we ask it to, or returns an error.
+
+	* search.c (Freplace_match): Arrange for markers sitting at the
+	beginning or end of the original text to float to the
+	corresponding position in the replacement text.
+
+1993-04-25  Eric S. Raymond  (eric@mole.gnu.ai.mit.edu)
+
+	* window.c (Fset-window-buffer):
+	Set horizontal-scrolling on a window to zero when
+	we connect it to a new buffer.
+
+	* buffer.c: Doc fix.
+
+1993-04-24  Jim Blandy  (jimb@totoro.cs.oberlin.edu)
+
+	Make the modifier manipulation functions more robust.  The old way
+	caused a bug once, and probably would again.
+	* termhooks.h (alt_modifier, super_modifier, hyper_modifier,
+	shift_modifier, ctrl_modifier, meta_modifier): Shift these all
+	down one bit in value, to avoid sign extension problems.
+	* lisp.h (CHAR_META, CHAR_CTL, CHAR_SHIFT): Fix these definitions too.
+	* keyboard.c (lispy_modifier_list): Ignore modifier bits beyond
+	what our table of modifier names can handle.
+	(apply_modifiers): Don't abort if you see extra modifier bits,
+	just remove them.
+
+1993-04-23  Eric S. Raymond  (eric@mole.gnu.ai.mit.edu)
+
+	* data.c (Fdefine_function):
+	Changed name back to Fdefalias, so we get things
+	in a known-good state.
+
+	* buffer.h (BUF_NARROWED, NARROWED):
+	New macros to test whether a region
+	restriction has narrowed the buffer.
+
+1993-04-17  Richard Stallman  (rms@mole.gnu.ai.mit.edu)

+	* fns.c (provide, require): Put appropriately-marked
+	conses in the current-globals list.
+
+	* lread.c (readevalloop):
+	New argument is the source file name (or nil if none).
+	All calls changed.  Do the two-step
+	necessary to call build_load_history with the correct current-globals
+	list for the current recursion.
+	(build_load_history): New function.
+	(eval_region, eval_buffer): Call readevalloop with new arg.
+	(load_history): New variable.
+
+1993-04-16  Eric S. Raymond  (eric@mole.gnu.ai.mit.edu)
+
+	* lread.c (readevalloop): New argument is the source file name (or
+	nil if none).  All calls changed.  Do the two-step
+	necessary to call build_load_history with the correct current-globals
+	list for the current recursion.
+	(build_load_history): New function.
+	(Feval_region, Feval_buffer): Call readevalloop with new arg.
+	(Vload_history): New variable.

+
+1993-04-16  Jim Blandy  (jimb@totoro.cs.oberlin.edu)
+
+	* fileio.c (Fmake_symbolic_link): If a file already exists under
+	the link's filename, delete the file which the link
+	would replace, not the file the link would point at.
+
+	* config.h.in (volatile): Don't define this to be the empty string
+	if some file has #defined HAVE_VOLATILE.
+
+	* emacs.c (SEPCHAR): Instead of defining this to be ',' on VMS and
+	':' elsewhere, just have it default to ':' if not #defined, and
+	#define it to be ',' in s/vms.h; OS/2 will need it to be ';'.
+	* s/vms.h (SEPCHAR): #define this to be ','.
+	* s/template.h (SEPCHAR): Mention this.
+
+1993-04-13  Jim Blandy  (jimb@totoro.cs.oberlin.edu)
+
+	* s/vms.h (xfree): #define this to emacs_xfree, to avoid case
+	conflict with XFree; on VMS, external symbols are case-insensitive.
+
+	* s/usg5-4.h (HAVE_GETTIMEOFDAY): Deleted; ../configure figures
+	that out now.
+
+	Changes for Emacs 19 from Thorsten Ohl <ohl@chico.harvard.edu>:
+	* s/mach2.h: copied from the Emacs 18.59 distribution.
+	Don't define NO_REMAP, define START_FILES as
+	`pre-crt0.o' instead.  Define LIB_MATH as `-lm', to override the
+	default `-lm -lc' (there is no libc on the NeXT).
+	* ymakefile (STARTFILES): Allow config.h to set this value even if
+	ORDINARY_LINK is defined.
+	* unexnext.c: Fix subdirectories for the machine dependent include
+	files for NeXTStep 3.0; #include <mach/mach.h> and
+	<mach-o/loader.h> instead of <mach.h> and <sys/loader.h>.
+	(getsectbyname): Remove prototype for this; the system #include
+	files take care of that.
+	(malloc_cookie): New variable.
+	(unexec_doit): Set malloc_cookie to the result returned by
+	malloc_freezedry.
+	* emacs.c (main): Declare malloc_cookie to be extern, so that we can
+	get the value set when we dumped and pass it to malloc_jumpstart.
+	* systime.h: The NeXT has a timezone function.
+
+1993-04-12  Jim Blandy  (jimb@totoro.cs.oberlin.edu)
+
+	* ymakefile ($(OLDXMENU)): Remove $(OLDXMENU) before trying to

+
+1993-04-10  Jim Blandy  (jimb@geech.gnu.ai.mit.edu)

+
+1993-04-09  Jim Blandy  (jimb@totoro.cs.oberlin.edu)
+
+	* keyboard.c (command_loop_1): Rebuild menu bar if
+	update_mode_lines is set.
+
+        long_to_cons and cons_to_long are generally useful things; they're

+	* xselect.c (long_to_cons, cons_to_long): Moved from here...
+	* data.c    (long_to_cons, cons_to_long): ... to here.

+
+	* xmenu.c (Qmenu_enable): Definition moved...
+	(syms_of_xmenu): ... along with initialization ...
+	* keyboard.c (Qmenu_enable): ... to here ...
+	(syms_of_keyboard): ... and here.
+
+	* keyboard.c (kbd_buffer_get_event): If we get a selection clear
+	or selection request event, but we were compiled without the
+	window-system-specific code to handle it, abort.  Don't try to
+	call a function which doesn't exist.
+
+	* keyboard.c (make_lispy_event): In the code which processes mouse
+	clicks, declare f to be a FRAME_PTR, not a struct frame *; this
+	works when MULTI_FRAME is not #defined.
+
+	* xfaces.c (sort_overlays): Define this to be static, as declared.
+
+	* callproc.c (relocate_fd): Make messages string literals, not
+	initialized arrays.
+
+	* alloc.c (__malloc_hook, __realloc_hook, __free_hook): Declare
+	these extern, not static.  (!)
+
+	* alloc.c (__malloc_hook, old_malloc_hook, __realloc_hook,
+	old_realloc_hook): Declare that the functions these point to return
+	void *, not void.
+
+        Adjust for autoconf merger.
+	* config.h.in: Add extra line to top, in case autoconf gets fixed
+	and decides not to add Makefile-style comments to the top of the
+	files it generates which we are forced to lop off.
+	Indicate that the boolean macros here get their definitions via
+	the DEFS Makefile variable.
+	Adjust the operating system and machine #includes to use
+	autoload's @cookies@.
+	(RETSIGTYPE): Give this a default value.
+	(SIGTYPE): Set this from RETSIGTYPE.
+	(LD_SWITCH_X_SITE, C_SWITCH_X_SITE): Get values via @cookies@.
+	* Makefile.in (DEFS): Renamed from CONFIG_CFLAGS.
+	(xmakefile): Pass CFLAGS to ${CPP}.
+
+	* buffer.c (Fmake_overlay, Fmove_overlay): New optional BUFFER
+	arguments.
+	(recenter_overlay_lists): New argument BUF, to use instead of the
+	current buffer.
+	(Foverlay_recenter): Pass the appropriate arguments to
+	recenter_overlay_lists.
+
+	* buffer.c (Fdelete_overlay): Don't assume that overlay is in the
+	current buffer.  Don't forget to declare the argument a Lisp_Object.
+
+	* dispnew.c (getenv): Extern declaration deleted; this is done in
+	config.h.
+
+	* Makefile.in (tagsfiles): Remove external-lisp from this list of
+	files; we're not distributing it, so the normal build process
+	shouldn't depend on it.
+
+	* dispnew.c (init_display): Compare the return value of getenv to
+	zero before setting display_arg, instead of just using the pointer
+	as a truth value.
+
+1993-04-08  Richard Stallman  (rms@mole.gnu.ai.mit.edu)
+
+	* xdisp.c (message, message1): If noninteractive and

+
+	* keyboard.c (echo_dash): Do nothing if echoptr is 0.

+
+1993-04-07  Jim Blandy  (jimb@geech.gnu.ai.mit.edu)
+
+	* keyboard.c (apply_modifiers): Fix typo in sanity check.
+
+	* keyboard.c (interrupt_input_blocked, interrupt_input_pending):
+	Remove `extern' keywords - these are the definitions.
+
+1993-04-07  Richard Stallman  (rms@mole.gnu.ai.mit.edu)
+
+	* blockinput.h (UNBLOCK_INPUT): Fix typo.
+	(interrupt_input_blocked): Make this signed int.

+
+1993-04-07  Jim Blandy  (jimb@wookumz.gnu.ai.mit.edu)
+
+	* m/imbrs6000.h: If we're using GCC, define ORDINARY_LINK instead
+	of defining LINKER to use cc.
+	* s/aix3-1.h (LINKER): Don't use cc for linking command if we're
+	using GCC.
+	* s/aix3-2.h (SYSTEM_MALLOC): Undefine this.
+
+	* xterm.c (updating_frame): Declare this extern instead of static,
+	so it's the same variable as the updating_frame in term.c.
+	(XTupdate_begin, XTupdate_end): Don't bother to set
+	updating_frame; the term.c functions take care of that for us.
+
+1993-04-05  Jim Blandy  (jimb@wookumz.gnu.ai.mit.edu)
+
+	* s/vms.h (EXEC_SUFFIXES): Add definition for this.
+
+1993-03-31  Jim Blandy  (jimb@geech.gnu.ai.mit.edu)
+
+	* xfaces.c: Doc fixes.
+
+	Put interrupt input blocking in a separate file from xterm.h.
+	This isn't specific to X, and it allows us to avoid #including
+	xterm.h in files that don't really have anything to do with X.
+	* blockinput.h: New file.
+	* xterm.h (BLOCK_INPUT, UNBLOCK_INPUT, TOTALLY_UNBLOCK_INPUT,
+	UNBLOCK_INPUT_RESIGNAL): These are now in blockinput.h.
+	(x_input_blocked, x_pending_input): Deleted; there are analogs
+	in blockinput.h called interrupt_input_blocked and
+	interrupt_input_pending.
+	* keyboard.c (interrupt_input_blocked, interrupt_input_pending):
+	New variables, used by the macros in blockinput.h.
+	* xterm.c: #include blockinput.h.
+	(x_input_blocked, x_pending_input): Deleted.

+	instead of writing it out.
+
+	* fns.c (internal_equal): If the operands are both numbers,
+	compare them numerically, so that (equal 1.0 1) => t.
+	Compare Lisp_Compiled objects like vectors.
+
+	Add lisp functions to raise and lower frames.
+	* termhooks.h (frame_raise_lower_hook): New hook.
+	* term.c (frame_raise_lower_hook): Define it.
+	* frame.c (Fframe_to_front, Fframe_to_back): New functions.
+	(syms_of_frame): defsubr them.
+	* xterm.c (XTframe_raise_lower): New function.
+	(x_term_init): Set frame_raise_lower_hook to XTframe_raise_lower.
+
+	* frame.c: Doc fixes.
+
+1993-01-24  Jim Blandy  (jimb@totoro.cs.oberlin.edu)
+
+	Make the cursor style a frame parameter.
+	* xterm.h (struct x_display): Rename the `text_cursor_kind' member
+	to `current_cursor'; add new member `desired_cursor'.
+	(FRAME_DESIRED_CURSOR): New accessor for new member.
+	* xterm.c (x_display_bar_cursor): Rewritten so as not to damage
+	the characters the cursor is displayed over, and to handle
+	transitions between box and bar styles.
+	(x_display_bar_cursor, x_display_box_cursor): Use current_cursor
+	instead of text_cursor_kind.
+	(Vbar_cursor): Delete external declaration.
+	(x_display_cursor): Use the FRAME_DESIRED_CURSOR accessor instead
+	of Vbar_cursor to decide how to draw the cursor.
+	* xfns.c (Vbar_cursor): Remove definition.
+	(Qbar, Qbox, Qcursor_type): New symbols. 
+	(syms_of_xfns): Init and staticpro them; remove DEFVAR for
+	Vbar_cursor.
+	(x_set_cursor_type): New setter.
+	(x_frame_parms): Add it to the list.
+	(Fx_create_frame): Get default values for the cursor type.
+
+	* frame.c (Fmouse_position): Pass the appropriate arguments to
+	*mouse_position_hook; the protocol was changed, but this caller
+	wasn't fixed.
+
+	* xterm.c (XTclear_frame): Call x_scrollbar_clear.
+	(x_scrollbar_clear): New function.
+
+	* xterm.c (XTflash): Totally rewritten.  Only defined if
+	HAVE_TIMEVAL and HAVE_SELECT are defined, since we use select for
+	our timing.
+	(timeval_subtract): New function, to help XTflash.
+	(x_invert_frame): Removed.  This didn't work anyway.
+	(XTring_bell): Remove "#if 0" around call to XTflash, and remove
+	calls to x_invert_frame.  If both HAVE_TIMEVAL and HAVE_SELECT
+	aren't defined, then just do the ordinary beep.
+
+	* window.c (Fscroll_other_window): Prefer windows on the selected
+	frame, then look for windows on other visible frames.
+
+	* keyboard.c (Fmouse_click_p): Removed; with the 'e' spec, this
+	isn't necessary anymore.
+	(syms_of_keyboard): Remove defsubr for it.
+	* keyboard.h (Fmouse_click_p): Remove extern declaration for it.
+
+	* xfns.c (gray_bits): Remove this declaration; the same data is in
+	<X11/bitmaps/gray>.  #include that instead.
+	[not HAVE_X11] (x_set_border_pixel): Use gray_width and
+	gray_height, instead of assuming that the bitmap is 16x16.
+	(x_make_gc): Instead of creating a pixmap and then calling
+	XPutImage to make it into a grey stipple, just call
+	XCreatePixmapFromBitmapData to do it all at once.
+
+	* xterm.c (x_text_icon): Move the request for font information
+	into the "not HAVE_X11" part of the function; the X11 code doesn't
+	need this.
+
+	* xterm.c (x_wm_set_icon_pixmap): Instead of setting the
+	icon_pixmap to None, just remove IconPixmapHint from the flags of
+	the XWMHints structure.
+
+	* window.c (Fprevious_frame): Use prev_frame when we get to the
+	end of the current frame, not next_frame.  Doc fix.
+	* frame.c (prev_frame): Remove "#if 0" from this function.  It
+	turns out we do need it, to make prev_frame work right.
+
+	* frame.c (next_frame): Check that FRAME is a live frame.
+
+	* frame.c (Fselect_frame): Remove "#ifdef MULTI_FRAME" clause
+	around the code which calls Ffocus_frame; this code is already
+	inside an "#ifdef MULTI_FRAME" clause.
+	(next_frame, prev_frame, Fnext_frame): For the same reasons,
+	remove the "#ifdef MULTI_FRAME" clause around these functions.
+
+	unread-command-event has been replaced by unread-command-events.
+	* commands.h (unread_command_event): Change extern declaration.
+	* keyboard.c (unread_command_event): Change the definition.
+	(syms_of_keyboard): Change DEFVAR, and adjust the docstring.
+	(command_loop_1, read_char, Finput_pending, Fdiscard_input,
+	quit_throw_to_read_char, init_keyboard): Change to use
+	unread_command_events, with the new semantics.
+	* lread.c (read_char): Same.
+	* minibuf.c (temp_echo_area_glyphs): Same.
+	* xterm.c (unread_command_event): Remove external declaration for
+	this; it is only used by obsolete code.
+
+	* Makefile.in: Some makes can't handle comments in the middle of
+	commands; move them to before the whole rule.
+
+1993-01-21  Jim Blandy  (jimb@totoro.cs.oberlin.edu)
+
+	* keyboard.c (make_lispy_event): When handling a mouse click event
+	on a window, change x and y from screen coordinates to window
+	coordinates even when the click isn't in the text area.
+
+	* xterm.c (x_scrollbar_create): Remove code which asks for
+	EastGravity for windows; Emacs can't correctly deal with them
+	moving around unexpectedly.
+
+	* xterm.c (XTread_socket): Minor reformatting.
+
+	* xterm.c (x_set_window_size): Always mark the frame garbaged.
+
+        * window.c (Vmouse_window): Variable removed; it can't be handled
+	properly without race conditions, and the events give you all the
+	information you need anyway.
+	(syms_of_window): Remove DEFVAR.
+	* callint.c (Fcall_interactively): Change the `@' spec to select
+	the window of the first parameterized event in the key sequence
+	which invoked the command, instead of using Vmouse_window, which
+	isn't even updated anymore.  Adjust the documentation
+	accordingly.
+
+1993-01-20  Jim Blandy  (jimb@totoro.cs.oberlin.edu)
+
+	* xterm.c (x_scrollbar_create): Set the scrollbars to use
+	EastGravity.
+
+	* keyboard.c (make_lispy_event): Deal with button releases with no
+	stored down-going position.  Make sure we always store a Qnil in
+	the right button_down_location element after using it.
+
+1993-01-19  Jim Blandy  (jimb@totoro.cs.oberlin.edu)
+
+	* frame.c (Fdelete_frame): Clear the frame's display after calling
+	the window-system-dependent frame destruction routine.  We
+	no longer need to pass the display as a separate argument to
+	x_destroy_window.
+	* xterm.c (x_destroy_window): Put the code which clears out f's
+	display here, right after we free the storage it points to.  Put
+	everything, including the code which clears x_focus_frame and
+	x_highlight_frame, inside the BLOCK/UNBLOCK_INPUT pair.
+
+	* dispnew.c (Fredraw_display): Undo change of Jan 12; redraw only
+	frames whose garbaged flag is set.  The change to
+	FRAME_SAMPLE_VISIBILITY on Jan 14 should address the problem better.
+
+	keyboard.c (read_char_menu_prompt): Test HAVE_X_WINDOWS, not
+	HAVE_X_WINDOW.
+
+	The CPP symbol indicating whether or not we have mouse menu
+	support under X Windows is HAVE_X_MENU, not not NO_X_MENU.
+	* emacs.c (main): Test HAVE_X_MENU, instead of NO_X_MENU.
+	* keyboard.c (read_char_menu_prompt): Same.
+	* ymakefile: Same.
+
+	* keyboard.c (read_char, read_char_menu_prompt): Use the
+	EVENT_HAS_PARAMETERS macro from keyboard.h, instead of writing it
+	out.
+
+	* keyboard.c (read_char_menu_prompt): Doc fix.
+
+	* keyboard.c (read_char_menu_prompt): Fix test for no menus;
+	comparing name to Qnil doesn't work if we are called with no maps.
+
+	* keymap.c (Fdefine_key): Call Fkey_description to make the string
+	to use in the error message.
+
+1993-01-18  Roland McGrath  (roland@churchy.gnu.ai.mit.edu)
+
+	* window.c (Fdisplay_buffer): Doc fix.
+
+1993-01-16  Jim Blandy  (jimb@wookumz.gnu.ai.mit.edu)
+
+	* xterm.c (x_window_to_scrollbar): Search frames'
+	condemned_scrollbars list as well; input might arrive during
+	redisplay.
+	(x_scrollbar_report_motion): Don't forget to BLOCK_INPUT.
+	(XTjudge_scrollbars): Clear the condemned scrollbar list before
+	traversing it, so we don't try to process an event on a scrollbar
+	we've killed.
+
+1993-01-15  Richard Stallman  (rms@mole.gnu.ai.mit.edu)
+
+	* keyboard.c (Frecent_keys): Doc fix.
+
+1993-01-14  Richard Stallman  (rms@mole.gnu.ai.mit.edu)
+
+	* window.c (Fwindow_at): Doc fix.
+
+1993-01-14  Jim Blandy  (jimb@totoro.cs.oberlin.edu)
+
+	* xterm.c (x_scrollbar_create): Include PointerMotionHintMask in
+	the event mask for scrollbars.
+
+	* dispnew.c (Fredraw_display): DEFUN was missing a closing paren.
+
+	* term.c (set_vertical_scrollbar_hook, condemn_scrollbars_hook,
+	redeem_scrollbar_hook, judge_scrollbars_hook): Removed dumbo
+	"externs" from these.  They're supposed to be real definitions.
+
+	* .gdbinit: Add "-geometry +0+0" to default args.
+	(xscrollbar): New command.
+
+	Make scrollbar structures into lisp objects, so that they can be
+	GC'd; this allows windows and scrollbars can refer to each other
+	without worrying about dangling pointers.
+	* xterm.h (struct x_display): vertical_scrollbars and
+	judge_timestamp members deleted.
+	(struct scrollbar): Redesigned to be a template for a Lisp_Vector.
+	(SCROLLBAR_VEC_SIZE, XSCROLLBAR, SCROLLBAR_PACK, SCROLLBAR_UNPACK,
+	SCROLLBAR_X_WINDOW, SET_SCROLLBAR_X_WINDOW,
+	VERTICAL_SCROLLBAR_INSIDE_WIDTH, VERTICAL_SCROLLBAR_TOP_RANGE,
+	VERTICAL_SCROLLBAR_INSIDE_HEIGHT, VERTICAL_SCROLLBAR_MIN_HANDLE):
+	New macros, to help deal with the lispy structures, and deal with
+	the graphics.
+	* frame.h (WINDOW_VERTICAL_SCROLLBAR): Macro deleted.
+	(struct frame): New fields `scrollbars' and
+	`condemned_scrollbars', for use by the scrollbar implementation.
+	[MULTI_FRAME and not MULTI_FRAME] (FRAME_SCROLLBARS,
+	FRAME_CONDEMNED_SCROLLBARS): Accessors for the new field.
+	* window.h (struct window): Doc fix for vertical_scrollbar field.
+	* frame.c (make_frame): Initialize the `scrollbars' and
+	`condemned_scrollbars' fields of the new frame.
+	* alloc.c (mark_object): Mark the `scrollbars' and
+	`condemned_scrollbars' slots of frames.
+	* xterm.c (x_window_to_scrollbar): Scrollbars are chained on
+	frames' scrollbar field, not their x.display->vertical_scrollbars
+	field.
+	(x_scrollbar_create, x_scrollbar_set_handle, x_scrollbar_move,
+	x_scrollbar_remove, XTset_vertical_scrollbar,
+	XTcondemn_scrollbars, XTredeem_scrollbar, XTjudge_scrollbars,
+	x_scrollbar_expose, x_scrollbar_handle_click,
+	x_scrollbar_handle_motion): Substantially rewritten to correct
+	typos and brainos, and to accomodate the lispy structures.
+
+	* xterm.c (x_scrollbar_background_expose): Function deleted; we
+	don't want anything in the background there after all.
+	(XTread_socket): Don't call x_scrollbar_background_expose.  We
+	don't care.
+
+	* frame.h (FRAME_SAMPLE_VISIBILITY): Make sure frame is marked as
+	garbaged whenever it goes from invisible to visible.
+	* dispextern.h (frame_garbaged): Move extern declaration from here...
+	* frame.h (frame_garbaged): ... to here.  The FRAME_SAMPLE_VISIBILITY
+	macro uses it now, and this seems to be just as modular.  Make a
+	new page, just for this and message_buf_print.
+	(struct frame): Doc fix for the `visible' field.
+	* process.c: #include "frame.h" instead of "dispextern.h"; the
+	only thing we care about from it is the frame_garbaged
+	declaration.
+	* ymakefile: Note dependency change.
+
+	* xfns.c (Fx_create_frame): After mapping the frame, call
+	SET_FRAME_GARBAGED, not just plain FRAME_GARBAGED.
+
+	* window.c (window_internal_width): New function, which accounts
+	for scrollbars if present.
+	* lisp.h (window_internal_height, window_internal_width): Add
+	extern declarations for these.
+	* dispnew.c (direct_output_for_insert, direct_output_forward_char,
+	buffer_posn_from_coords): Use window_internal_width instead of
+	writing out its definition.
+	* indent.c (compute_motion): Doc fix; mention scrollbars and
+	window_internal_width.
+	(pos_tab_offset, Fvertical_motion): Use window_internal_width
+	instead of writing it out.
+	* window.c (Fpos_visible_in_window_p, Fwindow_width, Fscroll_left,
+	Fscroll_right): Same.
+	* xdisp.c (redisplay, try_window, try_window_id,
+	display_text_line): Same.
+
+	* xdisp.c (display_string): Add new variable `f', to be W's
+	frame.  Use it to set desired_glyphs, and to get the frame's width
+	to decide whether or not to draw vertical bars.
+
+	* xdisp.c (display_text_line): If we're using vertical scrollbars,
+	don't draw the vertical bars separating side-by-side windows.
+	(display_string): Same thing.  Draw spaces to fill in the part of
+	the mode line that is under the scrollbar in partial-width
+	windows.
+
+	* xfns.c (Qvertical_scrollbars): New symbol.  Use it as the name
+	of the parameter which decides whether or not the frame has
+	scrollbars, instead of Qvertical_scrollbar.
+	(Fx_create_frame): Adjusted accordingly.
+	(syms_of_xfns): Initialize and staticpro Qvertical_scrollbars.
+	(x_set_vertical_scrollbar): Renamed to x_set_vertical_scrollbars.
+	(x_frame_parms): Adjusted accordingly.
+
+	* xterm.h (CHAR_TO_PIXEL_WIDTH, CHAR_TO_PIXEL_HEIGHT,
+	PIXEL_TO_CHAR_WIDTH, PIXEL_TO_CHAR_HEIGHT): Rewritten, using:
+	(CHAR_TO_PIXEL_ROW, CHAR_TO_PIXEL_COL, PIXEL_TO_CHAR_ROW,
+	PIXEL_TO_CHAR_COL): New macros.
+	* xfns.c [not HAVE_X11] (Fx_create_frame): Use the
+	PIXEL_TO_CHAR_{HEIGHT,WIDTH} macros to figure the frame's
+	character size, and the CHAR_TO_PIXEL* macros for vice versa.
+	* xterm.c (XTwrite_glyphs, XTclear_end_of_line, stufflines,
+	scraplines, dumprectangle, pixel_to_glyph_coords, x_draw_box,
+	clear_cursor, x_display_bar_cursor, x_draw_single_glyph,
+	x_set_mouse_position): Use the CHAR_TO_PIXEL_* macros.
+
+	* xterm.c (x_wm_set_size_hint): The max_width and max_height
+	members of the size_hints are expressed in pixels, not columns.
+
+	* xterm.c (x_set_window_size): Remove ibw var; it's not used.
+	Set FRAME_WIDTH (f) to cols instead of rows.  Duh.
+
+	* xterm.c (pixel_to_glyph_coords): Properly set *bounds to the
+	character cell bounding the position, even when the position is
+	off the frame.
+
+	* xfns.c (x_set_name): To request that the modelines be redrawn,
+	execute the statement "update_mode_lines = 1;" instead of the
+	silly statement "update_mode_lines;".
+
+	* xfns.c (x_set_vertical_scrollbars): Don't try to set the
+	X window's size if the frame's X window hasn't been created yet.
+
+	* xfns.c (x_figure_window_size): Set the frame's
+	vertical_scrollbar_extra field before trying to calculate its
+	pixel dimensions.
+
+	* xfns.c (x_window): When calling x_implicitly_set_name for the
+	sake of drawing the name for the first time, remember to clear and
+	set the frame's explicit_name member as well as its name member.
+	(Fx_create_frame): Set the frame's explicit_name member if the
+	user specified the name explicitly.
+
+	* xdisp.c (display_text_line): Use the usable internal width of
+	the window, as calculated above, as the limit on the length of the
+	overlay arrow's image, rather than using the window's width field,
+	less one.
+
+	* xdisp.c (redisplay): Call condemn_scrollbars_hook and
+	judge_scrollbars_hook whenever they are set, not just when the
+	frame has vertical scrollbars.
+
+	* termhooks.h (mouse_position_hook): Doc fix.
+	(set_vertical_scrollbar_hook): This doesn't return anything any
+	more, and doesn't take a struct scrollbar * argument any more.
+	(condemn_scrollbars_hook, redeem_scrollbar_hook,
+	judge_scrollbars_hook): Doc fixes.
+	* term.c (mouse_position_hook): Doc fix.
+	(set_vertical_scrollbar_hook): This doesn't return
+	anything any more.  Doc fixes.
+	* keyboard.c (kbd_buffer_get_event): Receive the scrollbar's
+	window from *mouse_position_hook and pass it to
+	make_lispy_movement, instead of working with a pointer to a struct
+	scrollbar.
+	(make_lispy_event): We don't need a window_from_scrollbar function
+	anymore; we are given the window directly in *EVENT.
+	Unify the code which generates
+	text-area mouse clicks and scrollbar clicks; use the same code to
+	distinguish clicks from drags on the scrollbar as in the text area.
+	Distinguish clicks from drags by storing a copy of the lispy
+	position list returned as part of the event.
+	(button_down_location): Make this a lisp vector, rather than an
+	array of random structures.
+	(struct mouse_position): Remove this; it's been replaced by a lisp
+	list.
+	(make_lispy_movement): Accept the scrollbar's window as a
+	parameter, rather than the scrollbar itself.
+	If FRAME is zero, assume that the other arguments are garbage.
+	(syms_of_keyboard): No need to staticpro each window of
+	button_down_location now; just initialize and staticpro it.
+	* window.c (window_from_scrollbar): Function deleted; no longer
+	needed.
+	* xdisp.c (redisplay_window): Just pass the window to
+	set_vertical_scrollbar hook; don't pass the scrollbar object too.
+	* xterm.c (XTmouse_position): Don't return a pointer to the
+	scrollbar for scrollbar motion; instead, return the scrollbar's
+	window.
+
+	* xterm.c (XTmouse_position): Entirely rewritten, using
+	XTranslateCoordinates.  Call x_scrollbar_report_motion to handle
+	scrollbar movement events.
+	(x_scrollbar_report_motion): New function, to help out
+	XTmouse_position.
+
+	* keyboard.c (apply_modifiers): Don't assume that the Qevent_kind
+	property of BASE is set when we first create the new modified
+	symbol.  Check that the Qevent_kind property is properly set each
+	time we return any symbol.
+
+	* termhooks.h (struct input_event): Replace the frame member with
+	a Lisp_Object member by the name of frame_or_window.  Doc fixes.
+	Remove the scrollbar member; instead, use frame_or_window to hold the
+	window whose scrollbar was clicked.
+	* keyboard.c (kbd_buffer_store_event, kbd_buffer_get_event,
+	make_lispy_event): Adjust references to frame member of struct
+	input_event to use frame_or_window now.
+	* xterm.c (construct_mouse_click, XTread_socket): Same.
+
+	* xterm.c (last_mouse_bar, last_mouse_bar_frame, last_mouse_part,
+	last_mouse_scroll_range_start, last_mouse_scroll_range_end):
+	Replaced with...
+	(last_mouse_scrollbar): New variable.
+	(note_mouse_movement): Clear last_mouse_scrollbar when we have
+	receieved a new motion.
+	(syms_of_xterm): Staticpro last_mouse_scrollbar.
+
+	* xterm.c (note_mouse_position): Renamed to note_mouse_movement,
+	because that's what it really does.
+	(x_scrollbar_handle_motion): Renamed to x_scrollbar_note_movement,
+	for consistency.
+	(XTread_socket): Adjusted.
+
+	* xterm.c (XTset_scrollbar): Renamed to XTset_vertical_scrollbar.
+	(x_term_init): Adjusted.
+
+	* keyboard.c (kbd_buffer_frames): Renamed to
+	kbd_buffer_frame_or_window, and made to exist even when
+	MULTI_FRAME isn't defined; single-frame systems might have
+	scrollbars.  Use it to GCPRO the frame_or_window field in the
+	event queue.
+	(kbd_buffer_store_event, kbd_buffer_get_event,
+	stuff_buffered_input): Set and clear the
+	appropriate element of kbd_buffer_frame_or_window, whether or not
+	MULTI_FRAME is #defined.
+	(read_avail_input): When reading characters directly from stdin,
+	set the frame_or_window field of the event appropriately,
+	depending on whether or not MULTI_FRAME is #defined.
+	(Fdiscard_input, init_keyboard): Zap kbd_buffer_frame_or_window,
+	not kbd_buffer_frames.
+	(syms_of_keyboard): Initialize and staticpro
+	kbd_buffer_frame_or_window, whether or not MULTI_FRAME is
+	#defined.
+
+	* keyboard.c (head_table): Make Qscrollbar_movement have a
+	Qevent_kind property of Qmouse_movement, not Qscrollbar_movement.
+
+	* keyboard.c (read_key_sequence): If we decide to throw away a
+	mouse event which has prefix symbols (`mode-line',
+	`vertical-scrollbar', etcetera), remember that we may have to
+	unwind two characters, not just one.
+
+	* keyboard.c (read_key_sequence): Doc fixes.
+
+	* keyboard.c (kbd_buffer_store_event): Fix reversed sense of test
+	for focus redirection.
+
+	* keyboard.c (read_char): Don't echo mouse movements.
+
+	* emacs.c (shut_down_emacs): New function.
+	(fatal_error_signal, Fkill_emacs): Call it, instead of writing it out.
+	* xterm.c (x_connection_closed): Call shut_down_emacs instead of
+	Fkill_emacs; the latter will try to perform operations on the X
+	server and die a horrible death.
+	* lisp.h (shut_down_emacs): Add extern declaration for it.
+
+	* xterm.c (x_error_quitter): Move the abort call to after we print
+	the error message.  No harm in that.
+
+	* xdisp.c (echo_area_display): Move the assignment of f and the
+	check for visibility out of the "#ifdef MULTI_FRAME" clause; they
+	should work under any circumstances.
+
+	* xdisp.c (redisplay_window): If we're not going to redisplay this
+	window because it's a minibuffer whose contents have already been
+	updated, go ahead and jump to the scrollbar refreshing code
+	anyway; they still need to be updated.  Initialize opoint, so it's
+	known to be valid when we jump.  Calculate the scrollbar settings
+	properly for minibuffers, no matter what they are displaying at
+	the time.
+
+	* xdisp.c (redisplay_windows): Don't restore the current buffer
+	and its point before refreshing the scrollbars; we need the buffer
+	accurate.
+
+1993-01-12  Richard Stallman  (rms@mole.gnu.ai.mit.edu)
+
+	* print.c (float_to_string): Add final 0 if text ends with decimal pt.
+
+	* dispnew.c (Fredraw_display): Redraw all visible frames.
+	Make the non-multi-frame version interactive.
+
+1993-01-11  Richard Stallman  (rms@mole.gnu.ai.mit.edu)
+
+	* fileio.c (Fset_default_file_modes, Fdefault_file_modes):
+	Renamed from Fset_umask and Fumask; sense of arg is reversed.
+	(Fwrite_region): Doc fix.
+
+1993-01-10  Richard Stallman  (rms@mole.gnu.ai.mit.edu)
+
+	* print.c (float_to_string): Add `.0' at end if needed.

+
+1993-01-09  Jim Blandy  (jimb@totoro.cs.oberlin.edu)
+
+	* fileio.c (Fdo_auto_save): Add CURRENT_ONLY argument, as

+
+1993-01-07  Jim Blandy  (jimb@totoro.cs.oberlin.edu)
+
+        * config.h.in: protect against multiple #inclusions.
+
+	* config.h.in: Add a declaration for getenv.
+
+	* xfns.c (Fx_get_resource): Add CLASS argument, to give class of
+	ATTRIBUTE.

+1993-01-03  Richard Stallman  (rms@mole.gnu.ai.mit.edu)
+
+	* xfns.c (Fx_get_resource): Use EMACS_CLASS to make class_key
+	even if SUBCLASS is specified.  I don't know whether that is
+	right, but that's what the doc says.

+	* xterm.c (x_focus_event_frame): New variable.
+	(XTread_socket): When we receive a FocusIn event that's not

+	have focus.
+
+	* xterm.c (XTread_socket): Remove special code in EnterNotify case
+	to handle scrollbars and fake mouse motion events.
+
+1992-12-19  Jim Blandy  (jimb@totoro.cs.oberlin.edu)
+
+	* floatfns.c (Flog): Fix unescaped newline in string.
+	* frame.c (Fnext_frame): Same.
+	* textprop.c (Fprevious_single_property_change): Same.
+	(syms_of_textprop): Same, for DEFVAR for
+	`interval_balance_threshold'.
+
+	Change the meaning of focus redirection to make switching windows
+	work properly.  Fredirect_frame_focus has the details.
+	* frame.h (focus_frame): Doc fix.
+	[not MULTI_FRAME] (FRAME_FOCUS_FRAME): Make this Qnil, which
+	indicates no focus redirection, instead of zero, which is
+	selected_frame.
+	* frame.c (make_frame): Initialize f->focus_frame to Qnil, rather
+	than making it point to frame itself.
+	(Fselect_frame): If changing the selected frame from FOO to BAR,
+	make all redirections to FOO shift to BAR as well.  Doc fix.
+	(Fredirect_frame_focus): Doc fix.  Accept nil as a valid
+	redirection, not just as a default for FRAME.
+	(Fframe_focus): Doc fix.
+	* keyboard.c (kbd_buffer_store_event, kbd_buffer_get_event): Deal
+	with focus redirections being nil.
+	* xterm.c (XTframe_rehighlight): Doc fix.  Deal with focus

+
+	* window.c (Fset_window_configuration): Don't restore the frame's

+
+	* ymakefile (ralloc.o): This no longer depends on xterm.h.

+	* Makefile.in (distclean, xemacs, doxemacs): Same.
+
+	* xterm.h (PIXEL_WIDTH, PIXEL_HEIGHT): Change name of parameter
+	from `s' to `f'; it's a frame pointer.
+
+1992-12-18  Jim Blandy  (jimb@totoro.cs.oberlin.edu)
+
+	* keyboard.c (kbd_buffer_frames): New vector, to GCPRO frames in

+	Qnil, to allow the frame to get GC'd.
+	(Fdiscard_input, init_keyboard): Clear all elements of
+	kbd_buffer_frames to nil.
+	(syms_of_keyboard): Create and staticpro kbd_buffer_frames.
+
+	* xterm.c (x_error_quitter): Just abort, so we can look at the

+
+1992-12-14  Jim Blandy  (jimb@totoro.cs.oberlin.edu)
+
+	* scroll.c (do_scrolling): When bcopying the max_ascent field from
+	current_frame to temp_frame, remember that max_ascent is an array
+	of shorts, not ints.
+
+	It's a pain to remember that you can't assign to FRAME->visible.
+	Let's change all references to the `visible' member of struct
+	frame to use the accessor macros, and then write a setter for the
+	`visible' field that does the right thing.
+	* frame.h (FRAME_VISIBLE_P): Make this not an l-value.
+	(FRAME_SET_VISIBLE): New macro.
+	* frame.c (make_terminal_frame, Fdelete_frame): Use FRAME_SET_VISIBLE.
+	(Fframe_visible_p, Fvisible_frame_list): Use FRAME_VISIBLE_P and
+	FRAME_ICONIFIED_P.
+	* dispnew.c (Fredraw_display): Use the FRAME_VISIBLE_P and

+	and backup files too.

+
+	* search.c (Fskip_chars_forward, Fskip_chars_backward): Return the
+	distance traveled.
+	(skip_chars): Return the distance traveled, as a Lisp_Object.
+
+	* macros.c (Fend_kbd_macro): Don't use XFASTINT to check if arg is
+	negative; XFASTINT only works on values known to be positive.
+	(Fexecute_kbd_macro): Check QUIT in the repetition loop.  If the
+	macro is null, no characters are actually being read, so this
+	matters.
+
+	* Makefile.in (srcdir): New variable, not fully implemented.
+	(xmakefile): Turn -g and -O in CFLAGS into C_DEBUG_SWITCH and
+	C_OPTIMIZE_SWITCH in C_SWITCH_SITE's definition.  Delete junk.cpp
+	when done.
+	* ymakefile (archlib): Variable definition deleted.  Run programs
+	from ../lib-src directly, or use ${archlibdir}.
+	(${etc}DOC): Run make-docfile from ${libsrc}, not ${archlib}.
+	(${archlib}make-docfile, ${archlib}emacstool): Use ${libsrc}, not
+	${archlib}.
+
+	* ymakefile (lisp): Don't include version.el in this list.
+
+	Give subprocess creation a way to find a valid current directory
+	for subprocesses when the buffer's default-directory is a handled
+	name.
+	* fileio.c (Funhandled_file_name_directory): New function.
+	(Qunhandled_file_name_directory): New file-name-handler operation.
+	(syms_of_fileio): Defsubr Sunhandled_file_name_directory, and
+	initialize and staticpro Qunhandled_file_name_directory.
+	* callproc.c (Fcall_process): Call Funhandled_file_name_directory
+	on the buffer's default directory.  Do it earlier in the function
+	so there's less to GCPRO.
+	* process.c (create_process): Don't check the validity of the 
+	buffer's default directory here...
+	(Fstart_process): Instead, do it here; if we call
+	Funhandled_file_name_directory here, there's less GCPROing to do.
+
+	* callproc.c (Fcall_process_region): Return the value returned by
+	Fcall_process.
+
+	* fileio.c (find_file_handler): Rename this to
+	Ffind_file_name_handler, and make it visible to lisp.  Add a QUIT

+	(syms_of_fileio): Mention this new function in the docstring for
+	Vfile_name_handler_alist.  defsubr Sfind_file_name_handler.

+
+	* fileio.c (syms_of_fileio): Add staticpros for Qexpand_file_name,

+	Qfile_name_nondirectory, Qfile_name_as_directory.
+
+1992-12-07  Jim Blandy  (jimb@totoro.cs.oberlin.edu)
+
+	* window.c (Fset_window_configuration): If we're restoring the
+	configuration of a dead frame, don't bother rebuilding its window
+	tree, restoring its focus redirection, or temporarily resizing it
+	to fit the saved window configuration.  If the frame which was
+	selected when the configuration was captured is now dead, don't
+	try to select it.
+
+	* frame.c (Fdelete_frame): Delete all the windows in the frame's
+	window tree, using delete_all_subwindows.
+	* window.c (delete_all_subwindows): Don't make this static
+	anymore.
+
+1992-12-03  Jim Blandy  (jimb@totoro.cs.oberlin.edu)
+
+        Make sure that frames' visible flag only changes at acceptable
+	times.  See FRAME_SAMPLE_VISIBILITY's comments for details.
+	* frame.h (struct frame): New fields called async_visible and
+	async_iconified.
+	(FRAME_SAMPLE_VISIBILITY): New macro, with MULTI_FRAME and
+	non-MULTI_FRAME definitions.
+	* xdisp.c (redisplay): Call FRAME_SAMPLE_VISIBILITY to set the
+	visible and iconified flags appropriately for each frame.
+	(message1): Call FRAME_SAMPLE_VISIBILITY to set the visible and

+	Expose, ExposeWindow, or UnmapWindow, set f->async_visible, not
+	f->visible.
+	(x_do_pending_expose, x_raise_frame, x_lower_frame,
+	x_make_frame_invisible, x_make_frame_visible, x_iconify_frame):
+	Test and set f->async_visible and f->async_iconified, not
+	f->visible or f->async_iconified.
+
+	* keyboard.c (kbd_store_ptr): Declare this to be volatile, if
+	__STDC__ is #defined.
+	(Fdiscard_input): Use cast to keep GCC from complaining about the
+	assignment of kbd_store_ptr to kbd_fetch_ptr.
+
+	* xdisp.c (redisplay): Use FOR_EACH_FRAME to apply
+	redisplay_windows to the root window of each frame.  This makes a
+	#ifdef MULTI_FRAME unneeded, but it also means we recompute
+	buffer_shared from scratch even on non-MULTI_FRAME configurations.
+	Don't skip elements of Vframe_list that aren't frames; go ahead
+	and crash here.
+
+	* xdisp.c (redisplay): Remove #ifdef MULTI_FRAME around the code
+	which updates separate minibuffer frames specially; there's
+	nothing there that won't work on a single-frame configuration.
+
+	* dispextern.h (struct frame_glyphs): Doc fix.
+
+1992-12-02  Jim Blandy  (jimb@wookumz.gnu.ai.mit.edu)

+
+	* process.c (wait_reading_process_input): Doc fix.
+
+1992-11-26  Richard Stallman  (rms@mole.gnu.ai.mit.edu)

+	(m68000, COMPILER_REGISTER_BUG): Defs deleted.
+	(SIGN_EXTEND_CHAR, LIB_X11_LIB, NO_T_CHARS_DEFINES, UNEXEC): Defined.

+
+1992-11-19  Jim Blandy  (jimb@totoro.cs.oberlin.edu)
+
+	* m/sparc.h: Don't include <sys/param.h> here; that screws up the
+	xmakefile.  Instead, include it in getloadavg.c, which is the only
+	place that uses LOAD_AVE_CVT, which is the only reason
+	<sys/param.h> was here in the first place.
+
+1992-11-15  Jim Blandy  (jimb@totoro.cs.oberlin.edu)
+
+	* dispnew.c [not MULTI_FRAME] (Fredraw_display): Pass the correct
+	number of arguments to mark_window_display_accurate.
+
+	* undo.c (Fprimitive_undo): Remove whitespace in front of #ifdef
+	and #endif.
+
+	* systty.h: Doc fix.
+	
+	* systty.h, process.c, buffer.h, callproc.c, sysdep.c, dired.c:
+	Added VMS changes from Roland Roberts.
+	* vmspaths.h: New version from Roland Roberts.
+
+	* xdisp.c (display_string): Use w's buffer's value of
+	tab-width to display the string, instead of the current buffer's,
+	which could be anything.
+
+	* s/sol2.h (LD_SWITCH_SYSTEM): Add -R option.
+
+	* process.c (read_process_output): Save, widen, insert the process
+	output, and then restore the restriction if inserting text outside
+	the visible region.
+
+1992-11-14  Jim Blandy  (jimb@totoro.cs.oberlin.edu)
+
+	* buffer.c (Ferase_buffer): Doc fix.
+
+	* dispnew.c (safe_bcopy): Use the right terminating condition in
+	the loop which uses multiple bcopy calls to transfer a block to an
+	overlapping higher block.
+
+1992-11-13  Jim Blandy  (jimb@totoro.cs.oberlin.edu)
+
+	* process.c (Fstart_process): Establish an unwind-protect to
+	remove PROC from the process list if an error occurs while
+	starting it.
+	(start_process_unwind): New function to help with that.
+	(create_process): There's no need to explicitly call
+	remove_process if the fork fails; the record_unwind_protect in
+	Fstart_process will take care of it.
+
+	* commands.h (unread_command_event): Doc fix.
+
+	Don't ever throw away switch-frame events.
+	* lread.c: #include "keyboard.h".
+	(Fread_char, Fread_char_exclusive): Don't signal an
+	error for or throw away switch-frame events; instead, put them off
+	until after we've found a character we can respond to.
+	* commands.h (unread_switch_frame): Declare this extern.
+	* keyboard.c (unread_switch_frame): Don't declare this static.
+	* ymakefile (lread.o): Note that this depends on keyboard.h.

+	* keyboard.c (Vlast_event_frame): Doc fix.
+
+	* process.c (wait_reading_process_input): Test the C preprocessor
+	symbol "ultrix", not "__ultrix__" to see if we should ignore
+	ENOMEM errors from select.
+
+	* fileio.c (Fexpand_file_name): Don't fiddle with "/." if it's the
+	entire string.
+
+	* buffer.c (Fbury_buffer): Make this behave as in 18.59, although
+	that behavior is very odd - only remove the buffer from the
+	selected window if BUFFER was nil or omitted.
+
+	* keyboard.c (read_char): Write composite events to the dribble
+	file properly.
+
+	* keyboard.c (init_keyboard): Initialize Vlast_event_frame to
+	Qnil, rather than the selected frame.
+

+
+	* keyboard.c (lispy_modifier_list): Added sanity check before
+	indexing into modifier_symbols.
+
+	* keyboard.c (add_command_key): When copying the contents of the
+	old this_command_keys to new_keys, remember to multiply size by
+	sizeof (Lisp_Object) to get the amount we really need to copy.
+
+	Rename unread_command_char to unread_command_event; it has
+	subtly different semantics now, and we should use
+	`make-obsolete-variable' to warn people.
+	* command.h (unread_command_char): Change name in extern declaration.
+	* keyboard.c (unread_command_char): Rename.
+	(command_loop_1, read_char, Finput_pending, Fdiscard_input,

+
+	* s/bsd4-2.h, s/bsd4-3.h: #define SIGNALS_VIA_CHARACTERS.
+	* process.c (process_send_signal): Put all the code for sending

+	whether to use the Berkeley-style or SYSV-style ioctls by seeing
+	which ioctl commands are #defined.
+
+	* minibuf.c (read_minibuf): If get_minibuffer gives the
+	new minibuffer a nil default directory, find another buffer with a
+	better default directory and use that one's instead.

+
+	* process.c (process_send_signal): Doc fix.
+
+	* keyboard.c (read_key_sequence): Don't use
+	save_excursion_{save,restore} to protect the caller against buffer
+	switches; use Fset_buffer and Fcurrent_buffer; redisplay might

+
+	* keyboard.c (kbd_buffer_get_event): When checking a mouse
+	movement for a frame switch, don't assume Vlast_event_frame
+	contains a Lisp_Frame object.
+
+1992-11-06  Richard Stallman  (rms@mole.gnu.ai.mit.edu)
+

+
+1992-11-04  Jim Blandy  (jimb@totoro.cs.oberlin.edu)

+	is built before we try to use it, even using a parallel make.
+

+	TCGETA, not TIOCGETP.
+	* systime.h [USG] (EMACS_GET_TZ_OFFSET): Assign to *(offset), not

+	Include USG in the list of systems that have a tzname array.
+
+	* keyboard.c (read_key_sequence): Removed the
+	replay_sequence_new_buffer label; replay_sequence should be here

+	[not MULTI_FRAME] (kbd_buffer_get_event): Don't try to generate
+	switch-frame events.
+
+	* buffer.c (init_buffer): If PWD is accurate, use it instead of
+	calling getwd.
+	#include <sys/types.h> and <sys/stat.h>, for the call to stat.
+
+        Indicate whether an autoload form stands for a keymap or not.
+	* eval.c (Fautoload): Renamed fifth argument TYPE.  Document the
+	fact that (eq TYPE 'keymap) means FUNCTION will become a keymap
+	when loaded.
+	(Fmacroexpand): Instead of assuming that every autoload
+	form with a fifth element is a macro, actually check the fifth
+	element against t and `macro', which are the only values which
+	denote macroness.
+	* keymap.c (get_keymap_1): Don't try to autoload OBJECT's function
+	unless the autoload form indicates that it's a keymap.
+
+1992-11-03  Jim Blandy  (jimb@totoro.cs.oberlin.edu)
+
+	* .gdbinit (mips): New command.
+
+1992-10-31  Richard Stallman  (rms@mole.gnu.ai.mit.edu)

+
+	Clean up errors due to treating Lisp_Objects like integers.
+	* abbrev.c (Funexpand_abbrev): Just assign the last abbrev's value

+	abbrev-symbol is a string.
+	* alloc.c (Frope_elt): Declare arguments to be Lisp_Objects.
+	* buffer.c (reset_buffer): Don't assign to b->save_length as if it
+	were an int; use XFASTINT.

+	declarations.
+	* bytecode.c (Fbyte_code): Use EQ to compare string_saved with
+	bytestr.
+	* casefiddle.c (operate_on_word): Declare end to be an int, not a
+	Lisp_Object.

+	* keyboard.c: #include dispextern.h.
+	(recursive_edit_unwind, command_loop, Fthis_command_keys): Declare
+	these to return Lisp_Objects at the very top of the file, to avoid
+	having them implicitly declared as ints.
+	(echo_char): Use EQ to compare C to help_char.
+	(read_char): Remember to apply XFASTINT to the return value of
+	Flength before using it.  Apply XINT to c when clearing its high
+	bits and meta bits, and when writing it to the dribble file.
+	(read_char_menu_prompt): Use EQ to compare obj with
+	menu_prompt_more_char and its control-character analog.
+	(read_key_sequence): Declare PROMPT to be char *, not a

+	* process.c: (status_convert): Declare this to return a
+	Lisp_Object at the top of the file.
+	(decode_status): Don't untag XCONS (tem)->cdr before storing it in
+	tem; tem is a Lisp_Object, too.
+	(process_send_signal): Declare this to be static void.  Don't
+	return Qnil; nobody cares.

+	(display_string): Test buffer_defaults.ctl_arrow using NILP,
+	instead of comparing it with zero.
+	* xfns.c (x_decode_color, Fx_color_display_p): x_screen_planes is
+	an int, not a Lisp_Object.
+	(x_set_mouse_color): Give separate error messages for the
+	different cursors we try to set.
+	(Fx_geometry): Declare STRING to be a Lisp_Object.
+	(Fx_create_frame): No need to use XSET to assign NAME to f->name;
+	they're both Lisp_Objects.
+	(adjust_scrollbars): Use XINT to access w->hscroll.
+	(Fx_open_connection): x_screen_count, x_release, x_screen_height,
+	x_screen_height_mm, x_screen_width, x_screen_width_mm,
+	x_save_under, and x_screen_planes are integers, not Lisp_Objects.

+	x_screen_height are ints, not Lisp_Objects.
+	* xterm.h (x_screen_count, x_release, x_screen_height,
+	x_screen_height_mm, x_screen_width, x_screen_width_mm,
+	x_save_under, x_screen_planes): Declare this as ints, to match
+	their definitions in xterm.c.
+	* ymakefile: Note the new dependencies caused by the new
+	#inclusions above.
+
+	* xdisp.c (last_arrow_position, last_arrow_string): Make these
+	static.
+
+	* process.c (pty_process): Variable deleted; it's no longer used.
+	(syms_of_process): Don't initialize it.
+
+	* buffer.h (struct buffer_local_types): This declaration needed an

+
+	* xdisp.c (message): Re-write this in terms of message1.

+	previous_echo_glyphs from message to here.
+
+	* keyboard.c (read_char): When returning an unread switch-frame
+	event, jump to reread_first to return it, rather than reread; this
+	makes sure the event gets echoed (if appropriate) and goes into
+	this_command_keys.
+
+	* keyboard.c (read_key_sequence): If the key sequence starts with
+	a mouse click, read the key sequence using the keymaps of the
+	buffer clicked on, not the current buffer.

+
+	* keymap.c: Deal with autoloaded keymaps properly.

+	* keyboard.c (follow_key): Ask get_keymap_1 to perform autoloads.
+	(read_key_sequence): When pursuing potential bindings in the
+	function key map, ask get_keymap_1 to perform autoloading.  This
+	is hardly important, but it's consistent.
+	* doc.c (Fsubstitute_command_keys): Ask get_keymap_1 to
+	perform autoloads.  Autoloading might GC; we need to GCPRO our
+	local variables now.
+	(Fdocumentation, Fdocumentation_property): Autoloading in

+	local variables now.

+
+1992-10-21  Richard Stallman  (rms@mole.gnu.ai.mit.edu)

+	message; let the minibuffer contents show through.
+	* minibuf.c (temp_echo_area_glyphs): Don't clear echo_area_glyphs

+	* lisp.h (CHECK_LIVE_WINDOW): New predicate.
+	(Qlive_window_p): Extern declaration for this.
+	* window.c (decode_window): Use CHECK_LIVE_WINDOW instead of

+
+	* window.c (check_frame_size): Don't define this extern; that
+	doesn't mean anything.
+
+	* xterm.c: Clean up some of the caps lock handling:
+	(x_shift_lock_mask): New variable.
+	(x_find_modifier_mappings): Set it, based on the modifier mappings.
+	(x_convert_modifiers): Use x_shift_lock_mask, instead of assuming
+	that the lock bit always means to shift the character.
+	(XTread_socket): When handling KeyPress events, don't pass an
+	XComposeStatus structure along to XLookupString.  When handling
+	MappingNotify events, call XRefreshKeyboardMapping for both
+	MappingModifier and MappingKeyboard events, not just the latter.

+	(obtain): Don't call check_memory_limits.
+	(obtain, relinquish, r_alloc_sbrk): Use (*real_morecore) in place

+	Don't initialize lim_data or warnlevel, and don't call get_lim_data.
+	(memory_warnings): Function removed.

+
+	* keyboard.c (Vlast_event_frame): Make this variable exist even
+	when MULTI_FRAME isn't #defined.  People might find it
+	necessary for writing correct programs, even when the programs
+	don't explicitly use multiple frames.
+	(read_char, kbd_buffer_store_event, kbd_buffer_get_event): No need
+	to test MULTI_FRAME before setting Vlast_event_frame.

+	is complete.
+	(read_char): If unread_switch_frame is set, return that value.
+	(command_loop_1): No need to check Vlast_event_frame and select

+	* keyboard.h (Qswitch_frame): Declare this extern.
+
+	* frame.c: #include "commands.h" and "keyboard.h".

+	* emacs.c (main): Call keys_of_frame.
+	* keymap.c (initial_define_lispy_key): New function, for defining

+
+1992-10-09  Jim Blandy  (jimb@totoro.cs.oberlin.edu)

+	Link against -loldX, to get the association table functions.
+
+	* xterm.c, xrdb.c: #include <stdio.h> before "xterm.h", to avoid

+
+1992-10-09  Richard Stallman  (rms@mole.gnu.ai.mit.edu)
+
+	* m/pyrmips.h: New file.

+
+1992-10-07  Jim Blandy  (jimb@wookumz.gnu.ai.mit.edu)
+
+	* m/sparc.h: Include <sys/param.h>, to define the FSCALE constant.
+
+	* ymakefile (YMF_PASS_LDFLAGS): Refer to the prefix-args program
+	using "./prefix-args", not just "prefix-args"; some people don't

+1992-10-06  Richard Stallman  (rms@mole.gnu.ai.mit.edu)
+

+
+1992-10-03  Jim Blandy  (jimb@wookumz.gnu.ai.mit.edu)
+
+	* keyboard.c (read_key_sequence): Treat mouse clicks on non-text
+	areas as if they were prefixed with the symbol denoting the
+	area clicked on - `mode-line', etcetera.
+	When we throw away an unbound `down-' event, reset mock_input as
+	well.
+
+	* keyboard.c (Qevent_symbol_element_mask, Qmodifier_cache): Two
+	new symbols, used to implement caches on event heads.  These take
+	the place of some of the caching that modify_event_symbol used to do.
+	(parse_modifiers_uncached, apply_modifiers_uncached,
+	lispy_modifier_list, parse_modifiers, apply_modifiers): New
+	functions, which replace format_modifiers and reorder_modifiers;
+	they can be useful elsewhere too.
+	(reorder_modifiers, modify_event_symbol): Re-implement these in
+	terms of parse_modifiers and apply_modifiers.  modify_event_symbol
+	now uses a much simpler cache, and takes advantage of the caches
+	maintained by parse_ and apply_modifiers.
+	(follow_key): Don't modify NEXT if KEY has no bindings.
+	(read_key_sequence): Drop unbound `down-' events, and turn unbound
+	`drag-' events into clicks if that would make them bound.  This
+	benefits from the rewriting of the modifier key handling code.
+	(syms_of_keyboard): Initialize and intern
+	Qevent_symbol_element_mask and Qmodifier_cache.
+
+	* keyboard.c (echo_prompt): Terminate the echo buffer properly
+	even when the string is too long to display in the minibuffer.
+	(echo_truncate): Just return echoptr - echobuf, rather than
+	calling strlen on echobuf.
+
+	* alloc.c (Fmemory_limit): New function.
+	(syms_of_alloc): Defsubr it.
+
+	* window.c (SAVE_WINDOW_DATA_SIZE): Define this using sizeof,
+	instead of just saying it's 7; that way, we won't get screwed if 
+	we add members to struct save_window_data.
+
+	* window.c (struct save_window_data): Save the currently selected
+	frame, too.
+	(Fset_window_configuration): Restore the frame's selected window
+	using Fselect_window, and then restore the selected frame using
+	Fselect_frame.
+	(Fcurrent_window_configuration): Record the currently selected
+	frame.  Update docstring to describe the information now recorded.
+
+1992-10-02  Jim Blandy  (jimb@wookumz.gnu.ai.mit.edu)
+
+	* process.c (wait_reading_process_input): Ultrix select seems to
+	return ENOMEM when interrupted.  So, under Ultrix, treat ENOMEM
+	like EINTR.
+
+	* keyboard.c (modifier_names): The modifier is named "control",
+	not "ctrl".
+
+	* keyboard.c (modify_event_symbol): Make sure that the unmodified
+	event header gets the proper properties set on it, by recursing
+	and letting the same code build the properties for all event symbols.
+
+	* keyboard.c (Qmouse_click): Fix typo which assigned `mouse-click'
+	symbol to Qmouse_movement.
+
+1992-10-02  Richard Stallman  (rms@mole.gnu.ai.mit.edu)
+
+	* undo.c (Fprimitive_undo):

+	* intervals.c: `copy_intervals' no longer static.
+
+	* intervals.h: Declare `copy_intervals'.
+
+	* buffer.c: #include intervals.h.
+
+	* ymakefile: New macro "INTERVALS", controlled by "USE_INTERVALS",
+	which defines the interval include file "intervals.h".
+	New entries for "intervals.c" and "textprop.c".
+
+	* lisp.h: Declare Qbuffer_or_string_p.
+
+1992-10-02  Jim Blandy  (jimb@wookumz.gnu.ai.mit.edu)
+
+	* xterm.c (x_find_modifier_meanings): If there are no
+	modifiers containing a Meta_ keysym, use the Alt keysyms to
+	denote meta.
+	(construct_mouse_click): Set the down_modifier bit on mouse
+	button press events.
+	(XTread_socket): When processing keypress events, use
+	x_meta_mod_mask when processing ordinary ASCII characters, not
+	just when processing function keys and other non-ASCII events.
+	(XTread_socket): If we receive a MappingNotify event with the
+	`request' member set to `MappingModifier', then call
+	x_find_modifier_meanings to refresh x_meta_mod_mask.
+
+	* window.c (Fset_window_configuration): Clean up the way we save
+	and restore the frame's size.
+
+	* termhooks.h (struct input_event): Doc fix.
+	(NUM_MOUSE_BUTTONS): New constant.
+	(click_modifier): New modifier.
+	(NUM_MODIFIER_COMBOS): Removed.
+
+	* keyboard.h (EVENT_HAS_PARAMETERS): Definition changed - all events
+	are not 5 elements long.
+	(EVENT_HEAD): Work correctly on all sorts of events, not just
+	events with parameters.
+	(EVENT_WINDOW, EVENT_BUFFER_POSN, EVENT_SCROLLBAR_BUTTON,
+	EVENT_WINDOW_POSN, EVENT_TIMESTAMP): These aren't useful
+	anymore; this information may appear twice in an event.  These
+	are replaced by the POSN_ accessors, which are meant to be
+	composed with the EVENT_START and EVENT_END accessors.
+	(EVENT_START, EVENT_END): Two new accessors, to get at the
+	starting and ending position of an event.
+	(POSN_WINDOW, POSN_BUFFER_POSN, PONS_SCROLLBAR_BUTTON,
+	POSN_WINDOW_POSN, POSN_TIMESTAMP): New macros, to futher
+	diasassemble the values returned by EVENT_START and EVENT_END.
+	* keyboard.c (echo_char, read_char): Apply EVENT_HEAD without first 
+	testing for EVENT_HAS_PARAMETERS; EVENT_HEAD works properly on
+	all sorts of events now.
+	(read_key_sequence): Use the new accessors to decide in which window
+	an event occurred.
+	* keymap.c (access_keymap, store_in_keymap,
+	Fsingle_key_description): No need to check for
+	EVENT_HAS_PARAMETERS before using EVENT_HEAD; the latter now
+	works properly on all sorts of events.
+
+	* keyboard.c (Qevent_unmodified): Replaced by...
+	(Qevent_symbol_elements): New property.
+	(syms_of_keyboard): initialize and staticpro the latter, not the
+	former.
+	* keyboard.h (Qevent_unmodified): Extern declaration replaced by...
+	(Qevent_symbol_elements): This.
+	(EVENT_HEAD_UNMODIFIED): Use the Qevent_symbol_elements
+	property, rather than the Qevent_unmodified property.
+
+	* keyboard.c (readable_events): This doesn't need to scan and
+	discard mouse release events anymore; it just uses
+	EVENT_QUEUES_EMPTY.
+	(kbd_buffer_get_event): No need to skip past mouse release events.
+
+	* keyboard.c (button_down_location): New variable, which
+	stores the location at which each button was pressed, so we
+	can build a complete drag event when the button is released.
+	(make_lispy_event): When a button is pressed, record its
+	location in button_down_location, and turn it into a `down'
+	event.  When a button is released, compare its release
+	location with its press location, and decide whether to call
+	it a `click' or `drag' event.
+	Change mouse movement events to be arranged like click events.
+	(format_modifiers): Note that the click modifier has no
+	written representation.
+	(modifier_names, modifer_symbols): New variables, used to
+	create the Qevent_symbol_elements property.
+	(modify_event_symbol): Change the format of the modified
+	symbol cache; there are too many modifier bits now to use a
+	vector indexed by a modifier mask.  Use an assoc-list instead.
+	Document the format of the cache.
+	Put the Qevent_symbol_elements property on each new symbol,
+	instead of a Qevent_unmodified property.
+	(symbols_of_keyboard): Put Qevent_symbol_elements properties on
+	the symbols specified in head_table, not Qevent_unmodifed properties.
+	Initialize and staticpro modifier_symbols, and staticpro the
+	window elements of button_down_location.
+
+	* xmenu.c: #include "keyboard.h".
+	(Fx_popup_menu): Use the event accessors defined in keyboard.h,
+	instead of writing out cars and cdrs.
+	* ymakefile: Note that xmenu.o depends on keyboard.h.
+

+	target of bcopy when relocating strings.
+	(init_alloc_once): Call INIT_INTERVALS.

+	compile an interval tree into it.

+
+1992-09-30  Jim Blandy  (jimb@wookumz.gnu.ai.mit.edu)
+

+	frame's selected window when we can't call Fselect_window.
+
+	* xterm.c (x_meta_mod_mask): New variable, indicating which X
+	modifier bits denote meta keys.
+	(x_find_modifier_meanings): New function, to set x_meta_mod_mask.
+	(x_convert_modifiers): Use that.
+	(x_term_init): Call x_find_modifier_meanings.
+
+	* data.c (Fmake_local_variable): If SYM forwards to a C variable,
+	swap in the value for the current buffer immediately.
+
+	* lisp.h: Doc elaboration for Lisp_Buffer_Local_Value.
+
+1992-09-29  Joseph Arceneaux  (jla@churchy.gnu.ai.mit.edu)
+
+	* textprop.c (Ferase_text_properties): Merge intervals when
+	possible.
+
+1992-09-29  Jim Blandy  (jimb@wookumz.gnu.ai.mit.edu)
+
+	* xselect.c (Qcut_buffer0): Symbol removed; we're using a new
+	interface to the cut buffer now.
+	(NUM_CUT_BUFFERS, cut_buffer_atom, cut_buffer_value,
+	cut_buffer_cached, cut_buffer_just_set): New variables.
+	(Fx_own_selection, Fx_selection_value): Dike out the code to
+	handle CUT_BUFFER0 requests.
+	(Fx_get_cut_buffer, Fx_set_cut_buffer, x_watch_cut_buffer_cache,
+	x_invalidate_cut_buffer_cache): New functions.
+	(syms_of_xselect): Don't bother to initialize Qcut_buffer0.
+	Initialize and staticpro cut_buffer_value, and defsubr
+	Sx_get_cut_buffer and Sx_set_cut_buffer.
+	* xterm.c (XTread_socket): Pass PropertyNotify events from the
+	root window to x_invalidate_cut_buffer_cache.
+	(x_term_init): Call x_watch_cut_buffer_cache here.
+
+	* keymap.c (access_keymap): Don't forget to QUIT while scanning
+	the keymap.
+
+	* keyboard.c (recent_keys): This needs to be staticpro'ed.  Change
+	it from a C array, which is a pain in the neck to staticpro, into
+	a lisp vector, which is easier.
+	(read_char, Frecent_keys): Access recent_keys as a lisp vector,
+	not a C array.
+	(syms_of_keyboard): Set recent_keys to be a vector, and staticpro it.
+
+	* ymakefile (xfns.o): This doesn't depend on xselect.c.
+
+	* xterm.h (ROOT_WINDOW): Use the DefaultScreen macro, not the
+	XDefaultScreen function.
+
+	* frame.c (Fdelete_frame): Call Fselect_frame with the appropriate
+	number of arguments.
+
+	* data.c (Frem): Use the `fmod' function under SunOS, Ultrix, and
+	HP/UX, not just under USG systems.
+
+	* buffer.c (Fbury_buffer): This used to undisplay the buffer being
+	buried only if the BUFFER argument was nil.  Instead, undisplay the
+	buffer whenever it's displayed in the selected window, no matter
+	how it was specified by BUFFER.  This is how it behaves in 18.58,
+	and I can't find any ChangeLog entry in 18.58 or 19.0 saying why
+	they differ.  Fix the doc string accordingly.
+
+1992-09-28  Jim Blandy  (jimb@wookumz.gnu.ai.mit.edu)
+
+	* frame.c (Fselect_frame, Fframe_root_window,
+	Fframe_selected_window, Fnext_frame, Fmake_frame_visible,
+	Fmake_frame_invisible, Ficonify_frame): Doc fixes.
+
+	* ralloc.c: Since the users of the relocating allocation code
+	handle memory exhaustion, it's better to return an error code to
+	them than to call abort. 
+	(obtain): If we cannot allocate more memory, don't call
+	abort.  Instead, return non-zero iff the allocation is successful.
+	(get_more_space): If obtain fails, return zero.
+	(get_bloc): Return zero if we can't allocate the new bloc.
+	(r_alloc_sbrk): Return zero if we can't allocate more memory.
+	(r_alloc): If we can't allocate more memory, set *PTR to zero and
+	return zero.
+	(r_re_alloc): If we can't allocate more memory, leave *PTR
+	unchanged, and return zero.
+
+	* ralloc.c (warnfunction): Renamed to warn_function; users changed.
+
+1992-09-28  Richard Stallman  (rms@mole.gnu.ai.mit.edu)
+
+	* insdel.c (del_range): Call record_delete before updating point.
+
+	* fileio.c (Finsert_file_contents): Do record_insert, then inc MODIFF.
+
+	* undo.c (record_delete): Record pos before the deletion.
+	(Fprimitive_undo): Go back to recorded position.
+
+1992-09-28  Jim Blandy  (jimb@wookumz.gnu.ai.mit.edu)
+
+	* window.c (delete_all_subwindows): Save the window's buffer in
+	its `height' field; we may need to know the window's old buffer
+	once we have restored it from a window configuration.
+	(Fset_window_configuration): When we restore a window, if its
+	`height' field is a buffer, restore its `buffer' field from that.
+	This allows us to leave the window's buffer unchanged if the
+	buffer recorded in the configuration is dead.
+
+	* window.c (delete_all_subwindows): Removed unused variable named
+	"count".
+
+1992-09-27  Jim Blandy  (jimb@wookumz.gnu.ai.mit.edu)
+
+	* keyboard.c (read_char): If we're returning an event from a
+	macro, set Vlast_event_frame to Qmacro, instead of leaving it set
+	to the frame of the previous real event.
+	(read_key_sequence): If Vlast_event_frame isn't a frame, don't
+	bother switching buffers.
+	(syms_of_keyboard): Doc fix for Vlast_event_frame.
+	(Vlast_event_frame): Doc fix.
+
+	* termhooks.h (alt_modifier, hyper_modifier, super_modifier,
+	down_modifier, drag_modifier): New modifiers, to support the new
+	input system.  Re-arranged modifiers so that their bits are in
+	canonical order; this makes reorder_modifiers slightly simpler.
+	* keyboard.c (format_modifiers, reorder_modifiers): Handle the new
+	modifier bits.
+
+	* keymap.c (access_keymap): Remove code to notice bindings for
+	Qt.
+
+1992-09-25  Richard Stallman  (rms@mole.gnu.ai.mit.edu)
+
+	* xmenu.c (single_keymap_panes): Handle vectors properly.
+
+1992-09-25  Jim Blandy  (jimb@geech.gnu.ai.mit.edu)
+
+	* keymap.c (Fwhere_is_internal): Don't forget to advance map to
+	the next element when we find something that is neither a vector
+	nor a cons.  Don't forget to QUIT in the appropriate places,
+	either.
+
+1992-09-23  Joseph Arceneaux  (jla@geech.gnu.ai.mit.edu)
+
+	* textprop.c (Fset_text_properties): Merge adjacent intervals with
+	the same properties.
+	(Fnext_single_property_change, Fprevious_single_property_change):
+	New subrs.
+
+	* intervals.c (merge_interval_left, merge_interval_right): Abort
+	if caller tries to merge first (or last, respectively) interval.
+	Delete the interval node after merging.
+	(copy_intervals): Use `split_interval_right' rather than creating
+	new intervals with make_new_interval and attaching them
+	explicitly.
+	(verify_interval_modification): Changed error message.  GCPRO
+	hooks before calling Fnreverse, and correctly Fcdr down the list.
+	Also, don't cons multiple copies of the same consecutive
+	modification hook.
+	(temp_set_point): New function.
+	(set_point): Call point-left and point-entered hooks if moving
+	between text with different properties.  Use the old and new
+	positions as arguments to these calls.
+
+	* intervals.c, intervals.h: (map_intervals, make_buffer_interval,
+	 make_string_interval,run_hooks): Deleted.
+
+1992-09-23  Jim Blandy  (jimb@wookumz.gnu.ai.mit.edu)
+
+	* keymap.c (DENSE_TABLE_SIZE): Doc fix.
+	(keymap_table): Function removed; this function exists only to
+	support an incorrect understanding of the format of keymaps.
+	(access_keymap, store_in_keymap, Fcopy_keymap,
+	Faccessible_keymaps): Correctly handle vectors at any point in the
+	keymap; don't assume it must be at the front.
+	(describe_map): Instead of calling describe_vector on the vector
+	in the cadr of the keymap (if present) and then calling
+	describe_alist to do the rest, just call describe_map_2.
+	(describe_alist): Renamed to describe_map_2; call describe_vector
+	when we encounter a vector in the list.
+	* xmenu.c (single_keymap_panes): Comment out the code which
+	tries to handle a dense keymap's table; it uses keymap_table, and
+	the rest of the code never uses the table contents anyway.
+
+	* keymap.c (access_keymap, store_in_keymap): Clarify error message
+	for non-ASCII characters.
+
+	* process.c [SIGCHLD && !BSD && !UNIPLUS && !HPUX]
+	(create_process): #if 0 out the code which sets the child's
+	handler for SIGCHLD to sigchld; the code which gives sigchld its
+	value has been diked out under these CPP symbols, so this should
+	be diked out too.
+
+	* indent.c (Fmove_to_column): Pass the right number of arguments
+	to Findent_to.
+
+1992-09-22  Jim Blandy  (jimb@kropotkin.gnu.ai.mit.edu)
+
+	* emacs.c (emacs_priority): Doc fix.
+	(main): Use nice, not setpriority; we just need a
+	simple, portable call to nice here.
+	* callproc.c (child_setup): Use nice, not setpriority.
+	* sysdep.c (sys_suspend): Don't try to use "nice (- nice (0))" to
+	set the subshell's priority to normal; nice doesn't return a
+	defined value on all systems.  Instead, since emacs_priority gives
+	the priority that Emacs was nastied to, we can use it to reset the
+	priority in a straightforward way.
+	[BSD4_1], [USG], [VMS] (setpriority): Remove dummy and
+	compatibility definitions of setpriority.
+
+	* keymap.c (access_keymap): Return the binding of Qt as the
+	binding for all unbound characters.
+
+	* fileio.c (syms_of_fileio): Don't try to defsubr Sunix_sync
+	unless it's actually been defined - that is, if unix is #defined.
+
+	* xrdb.c (x_get_resource): Cast the value being assigned to
+	ret_value->addr, rather than ret_value->addr itself; only GCC
+	allows you to cast lvalues.
+
+	* eval.c (unbind_catch): Do the long-jump here.  Take a VALUE
+	argument, which specifies the value to return to the catch, or the
+	data to give to the condition handler.  Renamed to
+	unwind_to_catch, to reflect new role.
+	(Fsignal, Fthrow): Removed code to set catch tag value and do the
+	long-jump; this is taken care of by unwind_to_catch.
+
+1992-09-21  Richard Stallman  (rms@mole.gnu.ai.mit.edu)
+
+	* alloc.c (mark_object): Avoid car recursion on cons with nil in cdr.
+	Avoid recursion on constants-vector of a compiled function.
+
+	* oldXMenu: Symlink deleted; anything that uses it needs fixing
+	in any case to work properly on systems without symlinks.
+
+1992-09-20  Richard Stallman  (rms@mole.gnu.ai.mit.edu)
+
+	* s/sol2.h: New file.
+
+	* fileio.c: Don't include sys/dir.h.
+
+	* s/usg5-4.h (LIBS_SYSTEM): Move non-default libraries here.
+	(LIB_STANDARD, START_FILES): Deleted.
+	(ORDINARY_LINK): Defined.
+
+	* ymakefile [ORDINARY_LINK]: Default LD to $(CC)
+	and make START_FILES and LIB_STANDARD empty.
+	(C_SWITCH_X_MACHINE, C_SWITCH_X_SYSTEM): New macros, default empty.
+	(CFLAGS): Use them.
+
+1992-09-19  Richard Stallman  (rms@mole.gnu.ai.mit.edu)
+
+	* ymakefile (${etc}DOC): Use OBJECTS_SYSTEM and OBJECTS_MACHINE.
+
+	* dired.c [VMS]: Include string.h, rms.h, rmsdef.h.
+	[VMS] (Ffile_version_limit): New function.
+
+	* sysdep.c (sys_suspend): Read EMACS_PARENT_PID envvar for parent. 
+
+	* syntax.c (scan_lists): When searching back for comment:
+	if comment-end is 2 chars, assume it does end a comment.
+	Otherwise, scan back to previous comment-end to see if there's
+	a comment starter between.  Also record whether the string quotes
+	between the start and the end are paired and uniform.
+	If so, skip to comment starter.  If not, scan from start of
+	defun to find comment starter if any.
+	(find_defun_start): New function.
+
+	* alloc.c (mark_object): Save last 500 values of objptr.
+	Check for clobberage of ptr, when marking a vector.
+
+1992-09-18  Richard Stallman  (rms@mole.gnu.ai.mit.edu)
+
+	* keymap.c (get_keyelt): Skip menu help string after menu item name.
+
+1992-09-18  Jim Blandy  (jimb@pogo.cs.oberlin.edu)
+
+	* buffer.c (Fget_buffer_create): Doc fix.
+
+	* lisp.h (struct handler): Remove the poll_suppress_count member
+	of this structure; it is always equal to the poll_suppress_count
+	of its catchtag structure.  The non-local exit code in eval.c is
+	difficult enough to understand as it is; needless duplication
+	doesn't help.
+	* eval.c (Fcondition_case): Rearranged for clarity.  Don't worry
+	about setting h.poll_suppress_count; it's guaranteed to be the
+	same as c.poll_suppress_count.
+	(internal_condition_case): Don't worry about
+	h.poll_suppress_count.
+	(Fsignal): Use h->tag->poll_suppress_count instead of
+	h->poll_suppress_count.
+
+	* eval.c (Fsignal): It's okay for the debugger to return to the
+	caller if the caller was signalling a quit.
+
+	* eval.c (unbind_catch): Restore the polling suppression count
+	here, instead of in Fsignal and Fthrow.
+	(Fthrow, Fsignal): Don't restore the polling suppression count here.
+	
+	* lisp.h (struct specbinding, struct handler): More documentation.
+	* eval.c (struct catchtag): More documentation.
+
+1992-09-17  Richard Stallman  (rms@mole.gnu.ai.mit.edu)
+
+	* ymakefile (LIBX): Don't use -loldX.
+
+1992-09-17  Jim Blandy  (jimb@pogo.cs.oberlin.edu)
+
+	* minibuf.c (get_minibuffer): Enable undo in minibuffers.
+
+1992-09-14  Richard Stallman  (rms@mole.gnu.ai.mit.edu)
+
+	* ymakefile (LIBXMENU): Check NO_X_MENU, not HAVE_X_MENU
+	* emacs.c (main): Use X menu code if HAVE_X_WINDOWS and not NO_X_MENU.
+	* keyboard.c (read_char_menu_prompt): Likewise.
+
+	* config.h.in: Delete everything about config.h.
+
+	* emacs.c: Eliminate HIGHPRI as compilation option.
+	(emacs_priority): New C variable, also Lisp variable.
+	(main): Set the priority iff emacs_priority is nonzero.
+
+1992-09-14  Jim Blandy  (jimb@pogo.cs.oberlin.edu)
+
+	* eval.c (entering_debugger): Variable renamed
+	when_entered_debugger, and is now a timestamp based on
+	num_nonmacro_input_chars.
+	(init_eval): Initialize when_entered_debugger, not
+	entering_debugger.
+	(call_debugger): Set when_entered_debugger to the current value of
+	num_nonmacro_input_chars.
+	(find_handler_clause): Don't call debugger unless
+	num_nonmacro_input_chars is greater than when_entered_debugger;
+	that way, we won't call the debugger unless the user has had a
+	chance to take control.
+	(Fbacktrace): Don't clear entering_debugger here.
+	* keyboard.h (num_nonmacro_input_chars): Added extern declaration
+	for this.
+
+	* fns.c (Fy_or_n_p): After testing for a QUIT, clear Vquit_flag.
+	Otherwise, if Fy_or_n_p is called while Vinhibit_quit is true and
+	the user presses C-g, this function goes into an infinite loop.
+
+	* dispnew.c (get_display_line): Don't abort if the frame is
+	invisible; since unmap events are handled at the interrupt level,
+	a screen may become invisible at any time.
+
+1992-09-13  Richard Stallman  (rms@mole.gnu.ai.mit.edu)
+
+	* fileio.c (Fverify_visited_file_modtime):
+	Pass buffer itself to handler, if have handler.
+	(Fwrite_region): GCPRO around Fexpand_file_name, Ffile_name_directory.
+	(Fread_file_name_internal): GCPRO around file name manip.
+	(Ffile_writable_p, Ffile_readable_p): Use abspath, not filename,
+	(Ffile_executable_p, Ffile_exists_p): to run the handler.
+	(Fset_file_modes, Ffile_directory_p, Ffile_modes): Likewise.
+	(Ffile_newer_than_file_p): GCPRO around expand_and_dir_to_file.
+
+1992-09-13  Jim Blandy  (jimb@pogo.cs.oberlin.edu)
+
+	* s/bsd4-3.h: Give the BSD4_3 and BSD symbols the same numeric
+	definitions they'll get in <sys/param.h>, to avoid warnings.
+
+	* m/hp9000s300.h: Don't include <sys/wait.h>.  This really
+	shouldn't be necessary.
+	(BIG_ENDIAN): Define this as "4321", to agree with
+	<machines/endian.h>, and avoid warnings.
+
+	* systime.h: Re-arrange inclusion of <sys/time.h> and <time.h> so
+	that they don't both get included under BSD, and do both get
+	included under AIX.
+
+	* xdisp.c (display_mode_line): If the only other frames are
+	minibuffer frames, don't name the frame after the in the selected
+	window.  We can use Fnext_frame to do this test easily.
+
+1992-09-12  Richard Stallman  (rms@mole.gnu.ai.mit.edu)
+
+	* process.c (Faccept_process_output): Initialize useconds.
+
+	* keyboard.c (num_nonmacro_input_chars): New variable.
+	(read_char): Use num_nonmacro_input_chars to decide on auto-save & gc.
+	Increment it when appropriate.
+	(record_auto_save): Use num_nonmacro_input_chars.
+
+	* fileio.c (Ffile_name_directory, Ffile_name_nondirectory): 
+	(Ffile_name_as_directory, Fdirectory_file_name, Fexpand_file_name): 
+	Call find_file_handler.
+	(syms_of_fileio): Set up Qfile_name_directory, etc.
+	(Fcopy_file): Call find_file_handler for newname as well as for filename.
+	(syms_of_fileio): Initialize Vfile_name_handler_alist.
+
+1992-09-11  Jim Blandy  (jimb@pogo.cs.oberlin.edu)
+
+	* callint.c (Fcall_interactively): Remove the 'K' interactive
+	code, in favor of 'e'; that's a better name.
+
+1992-09-11  Richard Stallman  (rms@mole.gnu.ai.mit.edu)
+
+        * s/esix5r4.h: New file.
+
+        * sysdep.c (init_sys_modes): Handle VDSUSP like V_DSUSP.
+        Use CDISABLE, not CDEL.
+        Turn off IEXTEN if it exists.
+        * systty.h (CDISABLE): New macro; may be defined from CDEL.
+
+	* keyboard.c (command_loop_1): Bind inhibit-quit to t when in Fsit_for.
+
+1992-09-10  Jim Blandy  (jimb@pogo.cs.oberlin.edu)
+
+	* Makefile.in: Add comments starting with "# DIST: " explaining
+	that this gets munged by the configure script.
+
+1992-09-10  Richard Stallman  (rms@mole.gnu.ai.mit.edu)
+
+	* s-aix3-1.h (HAVE_GETHOSTNAME): Defined.
+
+1992-09-09  Jim Blandy  (jimb@pogo.cs.oberlin.edu)
+
+	* frame.c (choose_minibuf_frame): abort if the selected frame has
+	nil in its minibuffer_window slot; this shouldn't happen any more.
+	* window.c (minibuffer_window): Accept an optional FRAME argument;
+	if specified, return the minibuffer used by that frame.
+
+	* keymap.c (describe_buffer_bindings): Adjust key_heading to match
+	the format used by describe_map_tree.  Also, don't reprint the
+	"key    binding" header above the global bindings if we've already
+	printed it for the local bindings; it's clear enough that the
+	columns mean the same thing as above.
+
+1992-09-08  Jim Blandy  (jimb@pogo.cs.oberlin.edu)
+
+        * ralloc.c (r_re_alloc): Instead of allocating a new bloc at the
+	end of the heap, copying the data to it, and then freeing the
+	original bloc, just expand the original block.  This saves a copy
+	and a call to sbrk, and also removes the large spike in memory
+	allocation that would occur when resizing large buffers.  And it's
+	less code.
+
+	* keyboard.h (Vkeyboard_translate_table): Declare this extern
+	here, so describe_buffer_bindings can use it.
+	* keymap.c (describe_buffer_bindings): Declare buf and bufend...
+
+1992-09-05  Jim Blandy  (jimb@pogo.cs.oberlin.edu)
+
+	* systime.h: Always #include <time.h>, not just when NEED_TIME_H
+	is defined.  It gets us struct tm.  #include <sys/time.h> whenever
+	HAVE_TIMEVAL is defined and NEED_TIME_H isn't.
+
+	* systime.h: Note that the tz_dsttime field of the struct timezone
+	returned by gettimeofday doesn't say whether daylight savings is
+	_currently- active; rather it specifies whether it is *ever*
+	active.
+	(EMACS_GET_TZ_OFFSET_AND_SAVINGS): Removed `savings_flag'
+	argument, and renamed to EMACS_GET_TZ_OFFSET.  Don't try to
+	extract savings information.  EMACS_CURRENT_TIME_ZONE should call
+	localtime to figure out whether DST is active.
+
+	* m/hp9000s300.h: #include <sys/wait.h> before doing anything
+	else, to avoid conflicts between the system's and Emacs's
+	definitions of BIG_ENDIAN.
+
+	* keymap.c (describe_buffer_bindings): Set the current buffer to
+	descbuf before calling current_minor_maps; that function's value
+	depends on the values of buffer-local variables.  Don't set the
+	current buffer to Vstandard_output until afterwards.
+
+	* keymap.c (describe_buffer_bindings): If
+	Vkeyboard_translate_table is in effect, describe its effects.
+
+	* frame.c (Fnext_frame): Doc fix.
+
+	* frame.c (prev_frame): #if 0'd out; nobody uses this.
+
+	* frame.c (next_frame): The logic which determines whether a frame
+	is acceptable to return was misarranged; rewrote it.
+	(prev_frame): Same thing.
+
+1992-09-05  Richard Stallman  (rms@mole.gnu.ai.mit.edu)
+
+	* syntax.c (scan_lists): Improve smarts for backwards scan of comments.
+	Don't modify comstyle inside that loop.
+	If string quotes don't match up, don't take value from OFROM;
+	instead, parse forward using scan_sexps_forward.
+	(scan_sexps_forward): Return value via a pointer passed in.
+	New element in state contains char addr of last comment-starter seen.
+	(Fparse_partial_sexp): Change call to scan_sexps_forward.
+
+1992-09-04  Richard Stallman  (rms@mole.gnu.ai.mit.edu)
+
+	* xmenu.c (xmenu_show): If no panes, just return.
+
+	* keyboard.c (last_nonmenu_event): New var.
+	(syms_of_keyboard): New Lisp var.
+	(read_key_sequence): Use that instead of prev_event.
+	* commands.h (last_nonmenu_event): Declared.
+	* callint.c (Fcall_interactively): For `K', use last_nonmenu_event.
+	Make `e' alias for `K'.
+
+1992-09-03  Jim Blandy  (jimb@pogo.cs.oberlin.edu)
+
+        * editfns.c (Fcurrent_time_string): Change docstring to
+        indicate that we will probably add the timezone to the end,
+        now that we have it available on many systems.
+
+	* xrdb.c: Don't include <X11/Xos.h>.  Under R4, it stupidly
+	insists on defining SIGCHLD, even if it already has a definition.
+	(file_p): Use the constant 4 instead of R_OK; empirically, the
+	number is more portable than the symbol if you count the #include
+	hair you have to go through to get R_OK defined.  Ffile_readable_p
+	does this too.
+
+	* xterm.c (x_wm_set_size_hint): Set the base_width and base_height
+	members of size_hints, if they're available (X11R4 and after);
+	otherwise, approximate the right thing, by using min_width and
+	min_height as the base size.
+
+1992-09-02  Barry A. Warsaw   (warsaw@anthem.nlm.nih.gov)
+
+	* Extended syntax.c in the following ways to support up to 2
+	orthogonal comment styles per mode.  This is needed for C++.
+	Bit 6 of syntax table entry for a character indicates
+	it is part of the `b' comment style.  Otherwise it is
+	part of the `a' style.
+	* syntax.h (SYNTAX_COMMENT_STYLE): New macro.
+	* syntax.c (Fmodify_syntax_entry): Set that flag for `b'.
+	(describe_syntax): Print the `b' flag.
+	(scan_lists, scan_sexps_forward): Handle the new flag.
+	(Fparse_partial_sexp): Return new element in value.
+
+1992-09-02  Roland McGrath  (roland@geech.gnu.ai.mit.edu)
+
+	* fileio.c (syms_of_fileio): Doc fix for Vfile_name_handler_alist.
+
+1992-09-02  Jim Blandy  (jimb@pogo.cs.oberlin.edu)
+
+	* keyboard.c (kbd_buffer_get_event): When performing the
+	FRAME_FOCUS_FRAME redirection, don't modify the frame field of
+	the event; that fatally corrupts mouse click events.  Instead,
+	just perform the redirection on the value assigned to
+	Vlast_event_frame.
+
+	* callint.c (Fcall_interactively): Don't try to get the
+	`enable-recursive-minibuffers' property from FUNCTION unless
+	FUNCTION is actually a symbol; there are some cases where a key
+	sequence is bound directly to a lambda form, and there's no reason
+	to break these.
+
+	* window.c (Fset_window_configuration): Don't signal an error
+	if the frame size saved in the window configuration doesn't
+	match the frame's current size; instead, temporarily resize
+	the frame while installing the window configuration.  This is
+	important because using the minibuffer saves and restores the
+	current window configuration, and you don't want to signal an
+	error just because the user resized the frame while using the
+	minibuffer.
+
+	* doc.c (Fsnarf_documentation): Signal an error if this is
+	called in a dumped Emacs.
+
+	* alloc.c (mark_object): mark a symbol's name after marking its
+	value, function, and property list rather than before; this way,
+	symbols' names are readable, giving us a chance to detect some
+	kinds of heap corruption.
+
+1992-09-02  Richard Stallman  (rms@mole.gnu.ai.mit.edu)
+
+	* emacs.c (__main, __do_global_dtors): New dummy functions.
+	(__do_global_ctors_aux, __do_global_ctors): Fix typo in fn names.
+
+1992-09-01  Jim Blandy  (jimb@pogo.cs.oberlin.edu)
+
+	* prefix-args.c: New file.  See comment at top of file.
+	* ymakefile (YMF_PASS_LDFLAGS): Use the prefix-args program to
+	affix the -Xlinker prefix to the linker arguments.
+	(prefix-args): New target.
+	(temacs): Depend on prefix-args.
+
+	* xterm.c (x_catch_errors): Don't forget to initialize
+	x_caught_error_message to the null string, so x_check_errors can
+	tell when an error has occurred.
+
+	* unexmips.c (mark_x): Declare this as static void at the top of
+	the file and at the function definition.
+
+	* keyboard.c (input_available_signal): Declare this to return
+	SIGTYPE.
+
+	* xrdb.c (getuid): Declare this to return short.
+
+	* s/bsd4-3.h: Remove definition of SIGTYPE macro; Mt. Xinu says
+	it's int, but Ultrix says it's void.  Since the SIGTYPE guessing
+	code in the `configure' script gives the correct answer for both
+	of these cases, there's no point in listing it here.
+
+	* systime.h (EMACS_CURRENT_TIMEZONE): Change documentation to
+	indicate that *OFFSET should be set to the number of minutes EAST
+	of Greenwich, which is what Ed Reingold says real time gurus want.
+	Changed the definition of the EMACS_GET_TZ_OFFSET_AND_SAVINGS
+	macro to reflect this.  Buggily, the Fcurrent_time_zone function
+	was already expecting minutes east of GMT.
+
+	* Makefile.in (distclean): Remove backups from the `m' and `s'
+	directories, too.
+
+	* m/mips.h: Merge changes from Emacs 18.58:
+	[NEWSOS5]: Changes so this file can be used with s/newsos5.h.
+	(SIGN_EXTEND_CHAR): Define this using a cast to signed char.  I
+	guess the MIPS compiler and its derivatives all have this type.
+	(HAVE_ALLOCA, C_ALLOCA): Define the former if we're compiling with
+	GCC, and the latter otherwise.
+	(C_SWITCH_MACHINE): Defined, instead of C_SWITCH_SYSTEM.
+	(LINKER): Defined, if BSD.
+	(XUINT, XSET, XUNMARK): Add parentheses to eliminate warnings from
+	GCC.  Reindent to fit in 80 columns.
+	INHIBIT_BSD_TIME prevents including bsd/sys/time.h.
+	* s/newsos5.h: New file for Sony NEWS-OS release 5, courtesy of
+	Chris Hanson <cph@klia.ai.mit.edu>.
+
+	* m/mips.h: Don't undefine LOAD_AVE_TYPE; the comment says that
+	Emacs 19 has the crocks to handle it properly.
+
+	* m/pmax.h: Merge changes from Emacs 18.58:
+	(LIB_STANDARD, COFF, TERMINFO): Cancel out definitions from
+	m/mips.h which are only appropriate for USG.
+	(MAIL_USE_FLOCK, HAVE_UNION_WAIT): Do define these.
+	(BROKEN_O_NONBLOCK): Defined.
+	(LINKER): Don't define this.
+	[OSF1]: Undef C_ALLOCA, define HAVE_ALLOCA.
+	
+	* s/osf1.h: New file.
+
+	* s/bsd4-3.h: Merge changes from Emacs 18.58:
+	(BSD, BSD4_3): Just define these, don't fret about numerical
+	values or version numbers.
+
+	* m/hp9000s300.h: Merge changes from Emacs 18.58, and hp300bsd.h:
+	Change configuration note to say it's okay to use this file for BSD.
+	Add comment saying that NOMULTIPLEJOBS must be defined for
+	versions of HP/UX before 6.5.
+	Don't define BIG_ENDIAN if it seems that <endian.h> has already
+	done so.
+        [BSD4_3] Define m68000, instead of hp9000s300; crt0.c uses these
+	to decide what sort of startup code to use.
+	[not BSD4_3] Under HP/UX, always define the BSD memory functions
+	(bcopy, bzero, and bcmp) in terms of the SYSV string functions
+	(memcpy, memset, and memcmp), not just under HP/UX 5; version 6's
+	BSD compatibility library has reported bugs in `signal'.
+	(NEED_BSDTTY): Move this symbol's definition inside the "not
+	BSD4_3" conditional, since it's only relevant to HP/UX.
+	* m/hp300bsd.h: File deleted, since m/hp9000s300.h now
+	works with both HP/UX and BSD; it includes m/hp300bsd.h's
+	specifications.
+
+	* m/hp9000s300.h: Remove definition for SIGN_EXTEND_CHAR; this is
+	only used by the regexp code, which has its own portable
+	definition these days.
+
+1992-08-31  Richard Stallman  (rms@mole.gnu.ai.mit.edu)
+
+	* keymap.c (Fmake_sparse_keymap): New optional arg.  Callers changed.
+	(Fmake_keymap): Likewise.
+
+	* emacs.c (__do_global_ctors, __do_global_ctors_aux): New dummy fns.
+	(__CTOR_LIST__, __DTOR_LIST__): New dummy variables.
+
+	* fileio.c (Fdo_auto_save): Always call record_auto_save.
+
+	* keyboard.c (read_char): Call read_char_menu_prompt here.
+	Accept 4 new args to pass to it.  Include them in recursive call.
+	Don't delay before starting echo if prev_event was a mouse event.
+	Test for eof in batch mode now understands C is a Lisp_Object.
+	(read_key_sequence): Don't call it here; always call read_char.
+	Don't change last_event_buffer after a mouse menu input.
+	(read_char_menu_prompt): Arg PROMPT deleted.
+	Return nil if nothing to do.
+
+	* xmenu.c (Fx_popup_menu): Treat coords relative to spec'd window.
+	(single_keymap_panes): New function; contains guts of keymap_panes.
+	If a command binding for submenu has a prompt string starting with @,
+	make a separate pane for it at this level.
+
+	* xfns.c (Fx_track_pointer): Pass new args to read_char.
+	(Fx_select_region, Fx_horizontal_line): Likewise.
+	* lread.c (Fread_char): Pass new args to read_char.
+	(Fread_event, Fread_char_exclusive): Likewise.
+	* fns.c (Fy_or_n_p): Pass new args to read_char.
+
+1992-08-30  Richard Stallman  (rms@mole.gnu.ai.mit.edu)
+
+	* keyboard.c (read_key_sequence): Keep track of prev_event.
+	Pass new proper args to read_char_menu_prompt.
+	(read_char_menu_prompt): New arg prev_event.  Use Fx_popup_menu.
+	Handle any number of keymaps, not just LOCAL and GLOBAL.
+	Invert meaning of arg PROMPT.  Test of menu_prompting was backwards.
+
+	* keymap.c (keymap_table): No longer static.
+
+	* xmenu.c (keymap_panes): New function.
+	(Fx_popup_menu): Accept keymap or list of keymaps as MENU argument.
+	Accept mouse button event as POSITION argument.
+
+1992-08-29  Richard Stallman  (rms@mole.gnu.ai.mit.edu)
+
+	* cmds.c (internal_self_insert): Assume Fexpand_abbrev expanded
+	something if it incremented MODIFF.
+
+1992-08-28  Richard Stallman  (rms@mole.gnu.ai.mit.edu)
+
+	* unexmips.c (unexec): Allow sections in any order.
+	Adjust addresses of rdata section as well as data section.
+
+	* buffer.c (syms_of_buffer): Made buffer-display-table,
+	buffer-field-list and buffer-undo-list allow any type of value.
+
+1992-08-27  Richard Stallman  (rms@mole.gnu.ai.mit.edu)
+
+	* fns.c (Fappend): Doc fix.
+
+1992-08-24  Jim Blandy  (jimb@pogo.cs.oberlin.edu)
+
+	* s/usg5-4.h: Incorporate changes from 18.58:
+	(LIBX10_SYSTEM): Undefine this.
+	(GNULIB): Definition deleted -- done in ymakefile.
+	(LIB_STANDARD): Don't use GNULIB.
+	(HAVE_TCATTR): Defined.
+
+	* xfns.c (x_icon): Don't call x_wm_set_icon_positions if the user
+	hasn't specified the icon position.  Let the window manager put
+	the icon where it likes.
+
+        * xterm.c (x_make_frame_invisible): Don't forget to check the
+	return value of XWithdrawWindow; it could indicate that the window
+	wasn't successfully redrawn.
+
+	* sysdep.c (init_baud_rate): Re-arranged order of conditionals -
+	test TERMIOS before TERMIO; when two options might both be
+	defined, test the most recent first, so that the most recent
+	functions get used.
+
+	* sysdep.c [HAVE_TERMIO] (init_baud_rate): Don't use tcgetattr
+	unless HAVE_TCATTR is defined.  Only very rarely do termio systems
+	have the tc{get,set}attr macros.
+
+	* window.c (coordinates_in_window): Do not assume that all
+	one-line windows are the minibuffer, or that all minibuffers are
+	one line high.  Use MINI_WINDOW_P.
+
+        * systerm.h: Renamed to systty.h, to be more consistent with
+	everything else in Unix.
+	* dispnew.c, emacs.c, keyboard.c, process.c, sysdep.c: #include
+	directive changed.
+	* ymakefile: References to systerm.h changed.
+
+	* s/usg5-3.h: Merged changes from 18.58:
+	(HAVE_SYSV_SIGPAUSE): Defined.
+	(BROKEN_TIOCGETC): Defined.
+
+1992-08-21  Richard Stallman  (rms@mole.gnu.ai.mit.edu)
+
+	* process.c (WCOREDUMP): Define only if not defined.
+	(create_process) [HAVE_SETSID]: Use TIOCSCTTY if exists.
+	
+1992-08-20  Jim Blandy  (jimb@pogo.cs.oberlin.edu)
+
+        * fileio.c (Fdo_auto_save): Call Fsleep_for with the appropriate
+	number of arguments.
+	* fns.c (Fyes_or_no_p): Same.
+
+	* dispnew.c (update_frame): Change the way we handle
+	cursor_in_echo_area.  Firstly, ignore this if the frame we're
+	updating doesn't have a minibuffer.  Secondly, don't handle the
+	selected frame specially.  Thirdly, don't assume that the
+	minibuffer is only one line high.  If cursor_in_echo_area < 0, put
+	the cursor in the upper-left corner; if cursor_in_echo_area > 0,
+	put it on the lowest non-empty line in the minibuffer window, or
+	on the top line.
+
+	* dispnew.c (direct_output_for_insert): Fail if
+	cursor_in_echo_area is set; we don't want to do the typing there.
+	(direct_output_for_insert): Same.
+
+1992-08-19  Jim Blandy  (jimb@pogo.cs.oberlin.edu)
+
+        * xterm.c (x_make_frame_invisible): Use XWithdrawWindow when
+	available [HAVE_X11R4]; send the UnmapNotify event when
+	appropriate [HAVE_X11]; just unmap the window if that's all that's
+	needed [not HAVE_X11].
+
+	* xterm.c (x_set_text_property): Removed; it's only called from
+	one place.  Who wants *another* layer of indirection?
+	* xfns.c (x_set_name): Use XSetWM{Name,IconName} when available
+	[HAVE_X11R4], or XSetIconName and XStoreName otherwise.
+
+	* xterm.h (FRAME_X_WINDOW): New macro, for readability.
+	* xterm.c, xfns.c, xselect.c: Use it.
+
+	* emacs.c (Fkill_emacs): Doc fix.
+	(syms_of_emacs): Doc fix for Vkill_emacs_hook.
+
+	* xterm.c (x_death_handler): Renamed to x_connection_closed.
+	(x_term_init): Use x_connection_closed as the SIGPIPE handler.
+
+	* xterm.c (acceptable_x_error_p, x_handler_error_gracefully,
+	x_error_handler): Removed; you can't catch X errors this way,
+	since you can't perform X operations from within an X error
+	handler, and even though we call error, we're still within an X
+	error handler.
+	(x_error_quitter, x_error_catcher): New functions, for panicking
+	on and catching X protocol errors.
+	(x_caught_error_message): Buffer for caught X errors.
+	(x_catch_errors, x_check_errors, x_uncatch_errors): New functions
+	for catching errors.
+	(x_term_init): Set the error handler to x_error_quitter, rather
+	than x_error_handler.
+	* xfns.c (x_set_mouse_color): Use x_catch_errors, x_check_errors,
+	and x_uncatch errors to avoid crashing if the user selects an
+	odd cursor.
+
+	* xterm.c (x_proto_requests): Removed; it's not important.
+	
+	* xterm.c (events): Array removed; it's not used.
+
+	* xfns.c (select_visual): Use XVisualIDFromVisual when available
+	[HAVE_X11R4].
+	
+	* xrdb.c (get_user_db): Use XResourceManagerString when available
+	[HAVE_X11R4].
+
+	* window.c (change_window_height): If the size of the window will
+	shrink below the minimum, this code would only try to delete it if
+	it had a parent.  Well, even if the window doesn't have a parent,
+	you want Fdelete_window to signal an error, since you're trying to
+	resize one of the undeleteable windows into nothingness.  So call
+	Fdelete_window even if the window doesn't have a parent.
+
+	* window.c (MINSIZE): Add kludge so that the minibuffer is always
+	allowed to shrink to one line in height.
+	(MINSIZE, CURBEG, CURSIZE): Change these so that their argument
+	are always Lisp_Objects, not struct window *'s.
+	(change_window_height): Changed accordingly.
+
+1992-08-18  Jim Blandy  (jimb@pogo.cs.oberlin.edu)
+
+        * frame.h (struct frame): New member - explicit_name.
+	* frame.c (make_frame): Clear it.
+	* xfns.c (x_set_name): Take new argument EXPLICIT, instead of
+	OLDVAL.
+	(x_explicitly_set_name, x_implicitly_set_name): New functions.
+	(x_frame_parms): Use x_explicitly_set_name here.
+	(x_window): Use x_implicitly_set_name here.
+	* xdisp.c (display_mode_line): Use x_implicitly_set_name here.
+
+	* xterm.c (x_wm_hints): Variable deleted.  This has to be
+	per-screen.  Duh.
+	* xterm.h (struct x_display): New member: wm_hints.
+	* xterm.c (x_wm_set_window_state, x_wm_set_icon_pixmap,
+	x_wm_set_icon_position): Use F->wm_hints, rather than x_wm_hints.
+	(x_term_init): Don't initialize x_wm_hints here.
+	* xfns.c (Fx_create_frame): Instead, initialize f->x_wm_hints
+	here.
+
+	* xterm.c (x_set_text_property): Properly balance the BLOCK_INPUTs
+	and UNBLOCK_INPUTs.  And remember that VALUE is the string we want
+	to set the name to, not PROPERTY.
+
+1992-08-17  Jim Blandy  (jimb@pogo.cs.oberlin.edu)
+
+	* frame.c (make_minibuffer_frame): Don't set this to auto-raise by
+	default.  It's annoying.
+
+	* frame.c (make_minibuffer_frame): Set the prev field of the
+	minibuffer window on a minibuffer-only frame to Qnil, rather than
+	having it point to itself.  This confuses code (Fprevious_window
+	and change_window_height, for example), and is only an attempt to
+	support a convention that can't really be used in Emacs 19 anymore.
+	* window.h: Document the fact that we can no longer assume that
+	the minibuffer's previous window is the root window, since a
+	minibuffer window in a minibuffer-only frame has a prev field of
+	nil.
+	* frame.h [not MULTI_FRAME] (FRAME_ROOT_WINDOW): Define this by
+	reference to the_only_frame.root_window, rather than by assuming
+	that minibuf_window->prev is the root window.  While this is true
+	in the non-multi-frame case, we want to discourage this assumption
+	in code.
+	* dispnew.c [not MULTI_FRAME] (Fredraw_display): Use
+	FRAME_ROOT_WINDOW instead of minibuf_window->prev.
+	* xdisp.c (redisplay, init_xdisp): Same.
+	* window.c (Fset_window_configuration): Removed #if 0'd code which
+	assumes that minibuf_window is on the same frame as the window
+	configuration.  Removed special case for windows whose prevs
+	point to themselves.
+
+	* window.c (Fset_window_configuration): Rename the argument from
+	ARG to CONFIGURATION, so it matches the docstring.  The
+	make-docfile program cares.
+
+	* window.c [MULTI_FRAME] (syms_of_window): Don't staticpro
+	minibuf_window; the frame list will take care of it.
+
+	* xterm.h (HAVE_X11R4): Since we can autodetect this, and can
+	write code more likely to be future-compatible, define this when
+	appropriate.
+	* xterm.c (x_set_text_property): Define this appropriately for
+	X11R3 and X11R4.
+
+	* xterm.c (x_set_text_property): Make this take a Lisp_Object
+	string as an argument, rather than a pointer and a length.
+	* xfns.c (x_set_name): Caller changed.
+
+	* xfns.c (x_get_arg): Accept a new type - symbol.  If we've
+	retrieved a string from the xrdb database and the user wants a
+	symbol, intern it.
+	(Fx_create_frame): Use the symbol type here.
+
+	* xfns.c (x_figure_window_size, x_icon, Fx_create_frame): Use
+	values from enum resource_types for the last arg to x_get_arg,
+	instead of passing numbers.
+
+	* xfns.c (Fx_create_frame): When setting up the scroll bars, use
+	the type parameter to x_default_parameter, rather than prefixing
+	the resource name with a question mark.
+
+	* xfns.c [not HAVE_X11] (Fx_create_frame): The resource which
+	determines whether or not to use a bitmapped icon is called
+	"IconType", not "BitmapIcon".  Update this.
+
+1992-08-15  Jim Blandy  (jimb@pogo.cs.oberlin.edu)
+
+	* xterm.c: Doc fixes.
+
+        More SYSV portability changes from Eric Raymond:
+
+	* xterm.c [USG5]: Don't include <sys/types.h>.
+
+	* xterm.c (x_make_frame_invisible): Instead of calling XWithdraw
+	window, which isn't widely available, write out what it does,
+	since that's not much.
+	(x_iconify_frame): Explicitly perform both the X11R3 and X11R4
+	methods for iconification; don't use XIconifyWindow, since that's
+	not present in R3.
+	
+	* xterm.c (x_wm_set_size_hint): Don't bother setting the
+	base_width and base_height members; their function is performed
+	just as well by the min_width and min_height members, and if we
+	use XSetNormalHints instead of XSetWMNormalHints, we can be
+	compatible with R3.
+
+	* xterm.c (x_error_handler): There is no way to invoke the default
+	error handler which works on all versions of X11, so don't bother;
+	call XGetErrorText and print the message ourselves.
+
+	* xterm.c (x_term_init): Don't use MAXHOSTNAMELEN; this isn't
+	defined on all systems.  Since we only use that as an initial
+	guess anyway, it's not very important.
+
+1992-08-14  Richard Stallman  (rms@mole.gnu.ai.mit.edu)
+
+	* abbrev.c (Fexpand_abbrev): If pre-expand hook changes the buffer,
+	assume that means we "did an expansion".
+
+	* cmds.c (internal_self_insert): Ignore value of Fexpand_abbrev;
+	instead, check whether buf is modified when it returns.
+
+1992-08-14  Jim Blandy  (jimb@pogo.cs.oberlin.edu)
+
+        Applied SYSV portability changes from Eric Raymond:
+
+	* xrdb.c [USG5]: Define SYSV, and then include <unistd.h>.
+	Apparently, Xlib.h include string.h if SYSV is defined, and
+	strings.h if not.
+	Don't include <sys/types.h>; just declare getuid to return an
+    	int.  Big deal.
+	(MAXPATHLEN): If this is not defined by the system's include
+    	files, give it a value of 256.
+	(get_user_db): Fetch the defaults directly from the display
+    	structure, rather than using XResourceManagerString; that
+    	function doesn't exist in the older versions of X.
+
+	* xterm.c (x_set_text_property): New function.
+	* xfns.c (x_set_name): Use it instead of XSetWMName and
+    	XSetWMIconName.
+
+	* xfns.c (select_visual): Fetch the visual id directly from v;
+    	don't call XVisualIDFromVisual, since that function is not
+    	available in earlier versions of X.
+
+	* term.c (term_get_fkeys): Some systems define `static' to be the
+    	empty string, which means that you can't have constant
+    	initialized arrays inside a function.  So move the `keys' array
+    	outside of the function.
+	* xdisp.c (decode_mode_spec): Same deal, with lots_of_dashes.
+	* xfns.c (x_make_gc): Same deal, regarding cursor_bits.
+
+	* term.c (keys): Include definitions for "K2" (the center key on
+    	an IBM keypad), "F1" (F11), and "F2" (F12).  Handle "k0" and "k;"
+    	specially; see the code for details.
+
+	* term.c (clear_end_of_line): Remember that on some systems,
+    	"static" gets defined to be the null string, so we can't declare
+    	an array to be static and then initialize it.  Since the array in
+    	question (buf) is only one element long, just make it a scalar
+    	rather than an array; it can then be initialized, even if it's
+    	not static.
+
+	* systime.h [not HAVE_TIMEVAL] (EMACS_USECS, EMACS_SET_USECS):
+    	Don't forget to define dummy versions of these.
+
+	* systime.h [USE_UTIME]: time_t is a typedef, not a struct.
+    	Don't prefix it with `struct'.
+
+	* systerm.h (EMACS_SET_TTY_PGRP): When there doesn't seem to be
+    	any way to do this, don't forget to give it a dummy definition.
+
+	* sysdep.c (select): There's no need to cast the return value of
+    	signal anymore, since we have the SIGTYPE macro defined.
+
+	* sysdep.c (read_input_waiting): When scanning for quit
+    	characters, use the value of quit_char, rather than assuming that
+    	C-g is the quit character.  And don't forget to declare i.
+
+	* sysdep.c [USG5]: Don't include fcntl.h.
+
+	* s/usg5-3.h: Eric Raymond writes:
+	Define HAVE_SELECT and BSTRINGS only if HAVE_X_WINDOWS is on,
+	because that means we'll be linking in the shared libraries
+	containing the BSD emulations.  Teach the file about the shared
+	libraries necessary to link X programs, because AT&T doesn't
+	supply static libraries for X.  Also, fix the incorrect assertion
+	that -lg cannot be used with SVr3.  Finally, force USE_UTIMES and
+	BROKEN_TIOCGWINSZ.  (Note for the future; there may be a
+	utimes(2)) emulation lurking in the X shared libraries.)
+
+	* s/usg5-4.h (USE_UTIME): Remove this definition; the C library
+    	still doesn't have utimes.
+
+	* ralloc.c (get_bloc): When initializing new_bloc->variable, cast
+	NIL to (POINTER *).
+	(malloc_init): Give warning if sbrk returns zero.  Wonder what
+	that's supposed to mean.
+
+	* process.c (process_send_signal): Don't send SIGTSTP if the
+	system doesn't have that facility.
+
+	* process.c: [USG5] Don't include <fcntl.h>.
+	[USG] Don't bother including <termios.h>, <termio.h>, or
+	<fcntl.h>; systerm.h takes care of all that.
+	Remove the "mis;tak-+;;" line from the code; apparently this
+	section of code does get used.
+
+	* minibuf.c (Fread_from_minibuffer): Put this function's doc
+	string into a comment; it's too long for the PCC preprocessor.
+	Rah.
+	(Fcompleting_read): Same deal.
+
+	* keyboard.c (init_keyboard): Changed "#endif SIGIO" to
+	"#endif /* SIGIO */"
+	* mocklisp.c (Fml_substr): Same sort of thing.
+	* process.c (wait_reading_process_input): Same.
+
+	* floatfns.c (Fexpm1, Flog1p): Function removed; it's not widely
+	available, and hardly vital.
+	(syms_of_floatfns): Adjusted appropriately.
+
+	* floatfns.c (Flog): Accept optional second arg, being the base
+	for the logarithm.
+	[USG] (Flogb): Define this in terms of Flog.
+
+	* data.c [USG] (Frem): Call fmod, rather than drem.  Rah.
+
+	* emacs.c [USG5]: Don't #include <fcntl.h> for these systems.
+
+	* alloc.c (Fmake_marker): Removed the test for being called from a
+	signal handler.  The original bug is probably gone, the test
+	wasn't written portably, and it should probably go somewhere else
+	anyway - say, funcall or eval.
+
+        End of changes from Eric Raymond.
+
+	* xfns.c (Fx_create_frame): Make the default for the icon-type
+    	parameter nil, not t.  It seems to cause problems with some X
+    	servers.
+
+	* lisp.h (DEFVAR_PER_BUFFER): Add new argument, TYPE, to help
+	check the types of buffer-local variable slots.
+	* buffer.c (syms_of_buffer): Call DEFVAR_PER_BUFFER with the new
+	TYPE argument.
+	* abbrev.c (syms_of_abbrev): Same.
+	* buffer.c (buffer_local_types): New variable.
+	(buffer_slot_type_mismatch): New function.
+	* buffer.h (buffer_local_types): New extern declaration.
+	* data.c (store_symval_forwarding): When storing through a
+	Lisp_Buffer_Objfwd, check if the slot requires a particular type,
+	and report an error if the types clash.
+	* lread.c (defvar_per_buffer): Support new TYPE argument, by
+	setting the appropriate slot in buffer_local_types.
+
+1992-08-13  Jim Blandy  (jimb@pogo.cs.oberlin.edu)
+
+	* window.c (window_loop): This used to keep track of the first
+	window processed and wait until we came back around to it.  Sadly,
+	this doesn't work if that window gets deleted.  So instead, use
+	Fprevious_window to find the last window to process, and loop
+	until we've done that one.
+
+	* window.c [not MULTI_FRAME] (init_window_once): Don't forget to
+	set the `mini_p' flag on the new minibuffer window to t.
+
+	* window.c (Fwindow_at): Don't check the type of the frame
+	argument.
+
+	* window.c [not MULTI_FRAME] (window_loop): Set frame to zero,
+	instead of trying to decode it.
+
+	* frame.h [not MULTI_FRAME] (the_only_frame): Put a comment above
+	this indicating that it's not GCPRO'd.  Put parens around some of
+	the FRAME_* macros' definitions.
+	[not MULTI_SCREEN] (Fselected_frame): New function.
+
+	* frame.h [not MULTI_FRAME] (FRAME_ROOT_WINDOW): Define this in
+	terms of minibuf_window, rather than by reference to
+	the_only_frame.
+	* window.c (init_window_once): Initialize minibuf_window before
+	FRAME_ROOT_WINDOW, so the latter actually points to something.
+
+	* keyboard.c (Fexecute_mouse_event): dyked-out function deleted.
+	We're not going to use this mouse interface.
+	(Vmouse_window, Vmouse_event, Vmouse_event_function,
+	Vmouse_left_hook, Vmap_frame_hook, Vunmap_frame_hook,
+	Vmouse_motion_handler): Variables deleted; they were to be used by
+	Fexecute_mouse_event.
+	(syms_of_keyboard): Same.
+	(command_loop_1): Remove dyked-out code to support
+	Fexecute_mouse_event.
+	(read_char): Same.
+
+	* keyboard.c (Vlast_event_frame): Don't define this window if
+	MULTI_FRAME is not #defined.
+	(syms_of_keyboard): Same.
+	(kbd_buffer_store_event): Don't try to work with Vlast_event_frame
+	if MULTI_FRAME is not #defined.
+	(kbd_buffer_get_event): Same.
+
+	* keyboard.c (Fdiscard_input): Removed dyked-out code from when
+	unread_command_char's quiescent value was -1, not nil.
+
+	* frame.c (make_frame): Stop passing zero to make_window; it's not
+	expecting any arguments.
+
+1992-08-12  Jim Blandy  (jimb@albert.gnu.ai.mit.edu)
+
+        * unexsunos4.c: Deleted "$Log" header in comments at top of file;
+	this was beginning to grow RCS hair, which we don't want.
+	* xmenu.c: Same deal.
+
+1992-08-11  Jim Blandy  (jimb@pogo.cs.oberlin.edu)
+
+        * fileio.c (Fread_filename): Don't add one here.
+	* minibuf.c (Fcompleting_read): Instead, stop subtracting one
+	here, so this function lives up to its doc string, which I think
+	specifies an okay way to work.
+
+	* doc.c (Vdata_directory): Removed; this is declared in callproc.c.
+	(syms_of_doc): Initialization removed.
+
+	* xfns.c (x_get_arg): Return Qunbound for an unspecified
+	resource, not nil.  That way, we can tell the difference between a
+	false resource and an unspecified resource.
+	(x_default_error): Use DEFLT if x_get_arg returns Qunbound, not Qnil.
+	(x_figure_window_size, x_icon, Fx_create_frame): Deal with
+	Qunbound and Qnil properly.
+
+	* xfns.c (Fx_create_frame): Pass the correct number of arguments
+	to x_set_font.
+
+	* xfns.c [not HAVE_X11] (Fx_create_frame): Delete section that's
+	only included if we *do* have X11.  Blind patching.
+
+        * xfns.c (x_icon): Rewritten to call x_wm_set_icon_position and
+	x_wm_set_window_state instead of calling XSetWMHints directly.
+	* xterm.c (x_wm_hints): New variable.
+	(x_wm_set_window_state, x_wm_set_icon_pixmap,
+	x_wm_set_icon_position): Use x_wm_hints.
+	(x_term_init): Set the `input' field of x_wm_hints, and its flag.
+
+	* xterm.c (x_text_icon): Call x_wm_set_icon_pixmap with a pixmap
+	of zero, to clear the pixmap.
+	(x_wm_set_icon_pixmap): Accept this protocol; if pixmap is zero,
+	specify no pixmap for the icon.
+
+	* xfns.c (x_default_parameter): Don't call store_frame_param here;
+	it's already taken care of by x_set_frame_parameters.
+
+	* xfns.c (Fx_create_frame): Check for the `icon-type',
+	`auto-raise', and `auto-lower' parameters. Have `icon-type'
+	default to t, indicating that we want the nifty gnu in our icons.
+	(Qauto_lower): New symbol.
+
+	* xfns.c (x_set_icon_type): UNBLOCK_INPUT before reporting the
+	error, not after.  error doesn't return, sklitch-brain.
+
+	* xterm.c (x_set_window_size): Call check_frame_size to make sure
+	that the requested dimensions are within acceptable limits.
+	Store the new size information in the frame structure.
+
+	* xfns.c (x_set_frame_parameters): Properly recognize changes to
+	the height of the frame.  Recognize changes of the frame's
+	position.
+
+	* xfns.c (x_set_frame_parameters): Iterate over ALIST while the
+	current element is cons, not while it's non-nil.
+	(syms_of_xfns): Call init_x_parm_symbols after interning all the
+	other atoms; init_x_parm_symbols expects Qx_frame_parameter to be
+	initialized.
+
+1992-08-10  Jim Blandy  (jimb@pogo.cs.oberlin.edu)
+
+	* xfns.c (Qbackground_color, Qborder_color,  Qborder_width,

+	Qsuppress_icon,  Qsuppress_initial_map,  Qtop,  Qundefined_color,
+	Qvertical_scroll_bar,  Qwindow_id,  Qx_frame_parameter): New

+	(syms_of_xfns): Initialize and staticpro them.
+	(Qheight, Qminibuffer, Qname, Qnone, Qonly, Qwidth,
+	Qunsplittable): Add extern declaration for these.
+	(x_init_parm_symbols): Don't initialize Qx_frame_parameter here;
+	it's done in syms_of_xfns.
+	(x_default_parameter): Change the argument char *PROPNAME into a
+	Lisp_Object PROP; let the caller take care of interning the atom.
+	(Fx_geometry, x_figure_window_size, x_icon, Fx_create_frame): Use
+	the new Q... variables, instead of interning things.
+
+	* frame.c (Qheight, Qicon, Qmodeline, Qname, Qnone, Qonly,
+	Qunsplittable, Qwidth, Qx): New symbol, with lisp code to rebuild
+	syms_of_frame.
+	(syms_of_xfns): Initialize and staticpro them.
+	(Fframep, Fframe_visible_p, Fframe_parameters):  Use
+	the new Q... variables, instead of interning things.
+	(store_in_alist): Change the argument char *PROPNAME into a
+	Lisp_Object PROP; let the caller take care of interning the atom.
+
+	* frame.c (Fframe_visible_p): Doc fix.
+
+	* frame.c (Fframe_parameters): When figuring the `minibuffer'
+	parameter, if FRAME doesn't have a minibuffer, return `none', not
+	nil.  If it does have a minibuffer with other windows, return the
+	window.
+
+	* frame.c (Fmodify_frame_parameters): Don't write out the loop for
+	processing X frame parameters here; do it in the x specific code.
+	Call the function which deals with this stuff
+	x_set_frame_parameters, not x_set_frame_parameter.
+	* xfns.c (x_set_frame_param): Replaced by x_set_frame_parameters.
+	(x_set_frame_parameters): Process the alist of parameters here.
+        Notice `width', `height', `top', and `left' parameters.
+        Hold off changing the frame size and position until the end, so we
+	can do both parameters at once when they are both specified.
+	(x_default_parameter): Call x_set_frame_parameters, not
+	x_set_frame_param.
+
+	* frame.c (Fmake_frame_visible, Fmake_frame_invisible,
+	Ficonify_frame, Fframe_parameters, Fmodify_frame_parameters,
+	Fset_frame_height, Fset_frame_width, Fset_frame_size,
+	Fset_frame_position): Place clauses controlled by FRAME_X_P inside
+	`#ifdef HAVE_X_WINDOWS ... #endif' clauses.
+
+	* frame.c (Fset_frame_position): Doc fix.
+
+	* dispnew.c (Fredraw_frame): Call clear_frame_records before
+	calling update_end, so that x_display_box_cursor can rely on the
+	contents of f->current_glyphs.
+
+	* xfns.c (x_figure_window_size): Indicate that this function
+	returns an int, rather than just leaving it unstated.
+
+	* xterm.c (x_wm_set_size_hint): Don't try to set the base_height
+	and base_width elements of size_hints if PBaseSize is not
+	#defined.  Set the minimum frame size according to the information
+	returned by check_frame_size.
+
+	* window.h (MIN_SAFE_WINDOW_HEIGHT, MIN_SAFE_WINDOW_WIDTH): Macros
+	removed.
+	(check_frame_size): New extern declaration.
+	* window.c (MIN_SAFE_WINDOW_HEIGHT, MIN_SAFE_WINDOW_WIDTH): Macros
+	defined here now.
+	(check_frame_size): New function.
+	* dispnew.c (change_frame_size): Call check_frame_size here,
+	rather than writing out its code.  Don't declare newheight and
+	newwidth to be register variables, since we take their address.
+
+	* bytecode.c (Fbyte_code): When metering the Bcall opcodes, make
+	sure the count on the symbol's `byte-code-meter' property does not
+	overflow.
+
+	* bytecode.c (syms_of_bytecode): Add a docstring for
+	byte-metering-on.
+
+1992-08-08  Jim Blandy  (jimb@pogo.cs.oberlin.edu)
+
+	* dispnew.c (in_display): Variable deleted; it's only ever used as
+	an unofficial parameter to change_frame_size.
+	(change_frame_size): New argument, DELAY, which when non-zero
+	indicates to delay the size change until later.  This should be
+	passed as one from signal handlers.
+	(window_change_signal): Call change_frame_size with a DELAY of 1.
+	(do_pending_window_change): Call change_frame_size with DELAY of 0.
+	* frame.c [MULTI_SCREEN] (Fset_frame_height, Fset_frame_width,
+	Fset_frame_size): Same.
+	[not MULTI_SCREEN] (Fset_frame_height, Fset_frame_width,
+	Fset_frame_size, Fset_screen_height, Fset_screen_width): Same.
+	* keyboard.c (Fsuspend_emacs): Call change_frame_size with the
+	proper arguments - the height and width are the second and third
+	arguments, not the first and second.  Pass 0 for DELAY.
+	* xfns.c (Fx_create_frame): Call change_frame_size with a DELAY of 0.
+	* xterm.c (XTread_socket, x_do_pending_expose): Call
+	change_frame_size with a DELAY of 1.
+	
+	* xterm.c (in_display): Deleted this; it's never used in xterm.c,
+	and there is another variable by the same name in dispnew.c.
+
+	* frame.c [not MULTI_SCREEN] (Fset_frame_height, Fset_frame_width,
+	Fset_frame_size, Fframe_height, Fframe_width): New functions, for
+	use when Emacs is not compiled with multiple screens.
+	[not MULTI_SCREEN] (Fset_screen_height, Fset_screen_width):
+	Functions added for backward compatibility with Emacs 18.  These
+	would be just aliases, except that the version 18 functions don't
+	take a FRAME argument.
+	[not MULTI_SCREEN] (syms_of_frame): New function, to defsubr the
+	above and add screen-height and screen-width as aliases for
+	Fframe_height and Fframe_width.
+	* emacs.c (main): Call syms_of_frame unconditionally.  When
+	MULTI_FRAME is not defined, it still provides the Fframe_width,
+	Fframe_height, Fset_frame_width, and Fset_frame_height functions.
+
+	* frame.c (Fset_frame_width): Change the size of FRAME, not of
+	selected_frame.
+
+	* frame.c (Fset_frame_width, Fset_frame_height): Declare the
+	`frame' argument to be a Lisp_Object.  It used to be undeclared.

+	frame macros.
+
+	* window.h (MIN_SAFE_WINDOW_WIDTH, MIN_SAFE_WINDOW_HEIGHT): New
+	macros.
+	* window.c (check_min_window_sizes): New function.
+	(set_window_height): Call it.
+	(Fsplit_window, change_window_height): Call it, instead of writing
+	out its code.
+	* dispnew.c (change_frame_size): If newlength or newwidth are too
+	small (according to the value of MIN_SAFE_WINDOW_{WIDTH,HEIGHT}),
+	force them larger.  This isn't really right, but it's better than
+	crashing.
+
+	* editfns.c (Fcurrent_time_zone): Doc fix.

+1992-07-30  Jim Blandy  (jimb@pogo.cs.oberlin.edu)
+
+	* keyboard.c (read_key_sequence): Scan for function keys when t >=

+
+1992-07-24  Richard Stallman  (rms@mole.gnu.ai.mit.edu)

+
+	* lread.c (Fread_char_exclusive): Code this with a do-while loop,
+	not a while loop with its body repeated.
+
+	* lread.c (Fread_event): Don't make this function's definition

+
+	* xfns.c (x_set_name): If ARG is nil, set the frame's name to the
+	current x_id_name.
+	* xdisp.c (display_mode_line): If we should set the frame's name,
+	but there is only one frame currently active, call x_set_name with
+	nil as the name; this will display samething generically
+	appropriate.
+
+1992-07-20  Jim Blandy  (jimb@wookumz.gnu.ai.mit.edu)
+	
+	* lread.c (isfloat_string): Recognize floats without a leading
+	integer part, noting that "e5" is a symbol, not a floating point
+	number.
+	
+	* xdisp.c (message, message1): When displaying a message, don't
+	make the minibuf frame visible unless the selected frame is also
+	visible.  This means that frames won't pop up unless the user is
+	actually interacting with Emacs.
+
+	* xdisp.c (display_mode_line): If Emacs is currently supporting
+	only one screen, don't change the title of the screen to the name
+	of the current buffer; this is only annoying in this case.  We
+	should probably think more carefully about how screens should be
+	named.
+
+1992-07-19  Richard Stallman  (rms@mole.gnu.ai.mit.edu)
+	
+	* process.c (allocate_pty): Handle PTY_OPEN.	
+	Delete system-specific alternatives to PTY_NAME_SPRINTF
+	and PTY_TTY_NAME_SPRINTF.	
+	
+1992-07-18  Richard Stallman  (rms@mole.gnu.ai.mit.edu)
+	
+	* callint.c (Fprefix_numeric_value): Fix typo: test raw, not val.
+	
+1992-07-17  Jim Blandy  (jimb@wookumz.gnu.ai.mit.edu)
+
+	* xfns.c (x_window): x_set_name normally ignores requests to set
+	the name if the requested name is the same as the current name.
+	This is the one place where that assumption isn't correct; f->name
+	is set, but the X server hasn't been told.  So fake it out.
+
+	* emacs.c [sun] (main): On suns, localtime caches the value of the
+	time zone rather than looking it up every time.  This means that
+	the dumped Emacs doesn't check the value of the TZ environment
+	variable.  Call tzset before entering the editing loop to check
+	the new TZ value.
+
+1992-07-16  Jim Blandy  (jimb@wookumz.gnu.ai.mit.edu)
+
+	* dired.c (Fdirectory_files): Don't forget to pass the REGP
+	argument to compile_pattern.
+	* search.c (compile_pattern): If REGP is zero, don't call
+	re_set_registers; nobody cares.
+
+	* fileio.c (auto_save_error): Pass the correct number of arguments
+	to Fsleep_for.
+
+	* lread.c: Include <ctype.h> at the top of the file, instead of
+	just before isfloat_string; read0 wants to use it too.
+
+	* process.c (Fdelete_process, Fprocess_status, Fprocess_send_region,
+	Fprocess_send_string, Fprocess_send_eof, Finterrupt_process): Doc
+	fixes.
+	
+	* process.c (Fprocess_status): Use get_process to find the process
+	denoted by the PROC argument, not Fget_process.
+
+1992-07-15  Richard Stallman  (rms@mole.gnu.ai.mit.edu)
+
+	* xdisp.c: Doc fix.
+
+1992-07-14  Jim Blandy  (jimb@wookumz.gnu.ai.mit.edu)
+
+	* window.c (syms_of_window): Doc fix for pop-up-frames.
+
+	* frame.c (Fframe_parameters): Note that if FRAME is omitted, it
+	defaults to the selected frame.
+
+	* frame.c (Fframe_height, Fframe_width): Blocked out these
+	functions; they have no C callers, and can be written nicely in
+	lisp.
+	
+	* frame.c (Fframe_pixel_size): Function removed; there aren't
+	enough other functions available to make this useful.  We need
+	functions describing the size of the characters of a font.
+
+	* xterm.h, xterm.c, xselect.c, xmenu.c, xfns.c, xdisp.c, window.h,
+	window.c, termopts.h, termhooks.h, termchar.h, term.c sysdep.c,
+	scroll.c, screen.c, screen.h, process.c, print.c, minibuf.c,
+	lisp.h keyboard.c, indent.c, fns.c, emacs.c, dispnew.c,
+	dispextern.h, cm.h, alloc.c, config.h.in: Screens are now called
+	frames, to avoid even more confusion with X terminology than
+	Emacs's "windows" already cause.  All macros, functions, and
+	variables renamed; all uses changed.
+	* screen.c, screen.h: Renamed to frame.c and frame.h.  All
+	#includers changed.
+	* ymakefile: Adjusted appropriately.
+	* buffer.c: Doc fixes.
+
+	* xfns.c (Fx_store_cut_buffer): Reversed sense of test for non-X
+	screen.
+
+	* window.c (Frecenter): Doc fix; this function places point in the
+	middle of the current window, not the current screen.
+
+	* window.c (temp_output_buffer_show): Use WINDOW_SCREEN macro
+	instead of accessing the member directly.
+
+1992-07-13  Jim Blandy  (jimb@wookumz.gnu.ai.mit.edu)
+
+	* print.c (print): Changed code which prints screen objects to use
+	the SCREEN_LIVE_P macro instead of testing the screen structure
+	directly.
+
+	* alloc.c (undo_threshold, undo_high_threshold): Variables renamed
+	to undo_limit and undo_strong_limit.
+	(Fgarbage_collect): Uses changed.
+	(syms_of_alloc): DEFVARs and docstrings changed.
+	* undo.c (truncate_undo_list): Comment adjusted.
+
+	* lread.c (read0): Allow floating-point numbers to begin with a
+	period.  `(0 .5)' denotes a list of two numbers, not a dotted pair.
+
+1992-07-11  Richard Stallman  (rms@mole.gnu.ai.mit.edu)
+
+	* fns.c, callproc.c: Doc fix.
+
+1992-07-10  Jim Blandy  (jimb@wookumz.gnu.ai.mit.edu)
+
+	* bytecode.c (Bsymbol_function, Bfset): Removed comments saying
+	that these are no longer generated.  Jamie Zawinski's byte
+	compiler does generate them, and he's actually collected
+	statistics on how often these functions are called.
+
+1992-07-09  Jim Blandy  (jimb@wookumz.gnu.ai.mit.edu)
+
+	* screen.c (store_screen_param): Clarify error message.
+
+	* xterm.c (x_make_screen_visible): Undo the change made on June
+	30; that is not the right solution.  Apparently there are three
+	states a window may be in: normal, iconified, and invisible.
+
+1992-07-08  Jim Blandy  (jimb@wookumz.gnu.ai.mit.edu)
+
+	* eval.c (Fmacroexpand): Code cleaned up; there's no need to
+	handle forms like ((macro lambda ...) ...) specially.
+
+	* fileio.c (Finsert_file_contents): Signal an error if we're asked
+	to read from a named pipe.
+
+1992-07-07  Jim Blandy  (jimb@wookumz.gnu.ai.mit.edu)
+
+	* m/*.h (SIGN_EXTEND_CHAR): Removed these definitions.  The only
+	place they were used is in regex.c, and nowadays that has its own
+	definition, which works for any machine.  The definitions in the
+	machine description files usually didn't work if given an unsigned
+	character as an argument, anyway.
+
+1992-07-04  Richard Stallman  (rms@mole.gnu.ai.mit.edu)
+
+	* buffer.c: Doc fix.
+
+1992-07-02  Joseph Arceneaux  (jla@churchy.gnu.ai.mit.edu)
+
+	* minibuf.c (Fdisplay_completion_list): Declared new variables
+	used in rms' previous change.
+
+1992-07-02  Richard Stallman  (rms@mole.gnu.ai.mit.edu)
+
+	* minibuf.c (Fdisplay_completion_list): Handle non-buffer stream.
+
+1992-07-01  Roland McGrath  (roland@churchy.gnu.ai.mit.edu)
+
+	* window.c (Fdisplay_buffer): Add interactive spec.
+
+1992-06-30  Joseph Arceneaux  (jla@churchy.gnu.ai.mit.edu)
+
+	* mem_limits.h: EXCEEDS_ELISP_PTR declared here.
+	* ralloc.c: No longer declared here.
+	* vm-limit.c: Nor here.  Also, include "lisp.h" before
+	"mem_limits.h" and additionally include "config.h".
+
+1992-06-30  Jim Blandy  (jimb@pogo.cs.oberlin.edu)
+
+	* xterm.c (x_make_screen_visible): Don't de-iconify the window;
+	iconification is orthogonal to visibility.
+
+	* emacs.c (syms_of_emacs): Change docstring for `kill-emacs-hook'
+	to describe it as a hook, not as a single function.
+
+1992-06-29  Jim Blandy  (jimb@pogo.cs.oberlin.edu)
+
+	* minibuf.c (Fread_no_blanks_input): Corrected maximum number of
+	arguments from one to two.
+
+	* emacs.c (Vkill_emacs_hook): Declare this here; it should have a
+	docstring, so we might as well DEFVAR it.
+	(syms_of_emacs): initialize it, and DEFVAR_LISP it with an
+	appropriate docstring.
+
+1992-06-28  Jim Blandy  (jimb@pogo.cs.oberlin.edu)
+
+	* lread.c (Feval_buffer): Make the DEFUN match the C argument
+	list; this takes two optional arguments, not just one.
+
+	* lisp.h (Lisp_Buffer_Local_Value): Comments neatened.
+
+	* data.c (Fset): Fixed conditional which tests whether the cache
+	is invalid.  It used to be pretty munged, and would always declare
+	the cache invalid for Lisp_Buffer_Local_Value variables.  Now it
+	declares the cache invalid if the buffer is wrong (obviously), of 
+
+1992-06-27  Jim Blandy  (jimb@pogo.cs.oberlin.edu)
+
+	* data.c (Fset): Comments reformatted for readability.
+
+	* xterm.c (last_mouse_movement_time): New variable.
+	(note_mouse_position): Set it.
+	(XTmouse_position): Return its current value as the position's
+	timestamp.
+
+	* keyboard.c (Qvertical_split): Renamed to `vertical-line',
+	since the window arrangement is actually referred to as a
+	`horizontal split.'
+	(make_lispy_event, make_lispy_movement, syms_of_keyboard): Uses
+	renamed here.
+	keyboard.h (Qvertical_split): Extern declaration changed here.
+	window.c (Fcoordinates_in_window_p): Changed this to return
+	`vertical-line' at the appropriate times, rather than
+	`vertical-split'.
+
+	* window.c (Fcoordinates_in_window_p): Put symbol names in
+	opposing single quotes - `vertical-split', for example.
+
+	* fileio.c (Fexpand_file_name): Don't signal an error if USERNAME
+	in a "~USERNAME/..." filename isn't a real user; just leave the
+	"~USERNAME" unchanged.
+
+	* fileio.c (Fmake_symbolic_link): Rename argument `NEWNAME' to
+	`LINKNAME', to conform with the docstring.
+
+	* Makefile.in (CPP): Pass `-Is -Im' to CPP, to make sure that
+	machine- and system-dependend files can include each other
+	properly.
+	* ymakefile (CFLAGS): Add those directories to the #include path
+	here too.
+
+	* Makefile.in (xmakefile): Build this via a temporary file, so
+	that if preprocessing fails we don't nuke the xmakefile.
+
+	* fileio.c: There are two versions of Fexpand_file_name defined
+	here; the latter is inside a `#if 0' clause.  Change its DEFUN to
+	a DEAFUN, so that its docstring doesn't make it into the DOC file
+	and supercede the real docstring.
+
+	* callint.c (Fcall_interactively): For the 'K' interactive spec,
+	set varies[i] to -1, indicating that the mouse click should be
+	quoted if the function makes it into the command history, and that
+	this argument by itself does not qualify the command to be
+	recorded in the history.
+
+1992-06-26  Jim Blandy  (jimb@pogo.cs.oberlin.edu)
+
+	* data.c (Frem): The drem function will sometimes return a
+	negative number.  If it does, add the divisor to it, to make it
+	positive.
+
+	* screen.c: Put '#ifdef MULTI_SCREEN' after the inclusion of
+	config.h.
+
+	* window.c (Fpos_visible_in_window_p): Remember to apply XSCREEN
+	to w->screen before applying SCREEN_WIDTH.
+
+	* screen.h [not MULTI_SCREEN] (last_nonminibuf_screen): Removed
+	#definition of this; it's confusing when debugging.
+	* screen.c (last_nonminibuf_screen): Variable moved from here...
+	* dispnew.c (last_nonminibuf_screen): to here, beside
+	selected_screen.  They should both exist, even if the multi-screen
+	support is not present.
+
+	* dispnew.c [not MULTI_SCREEN] (the_only_screen): New variable.
+	Instead of having the non-multi-screen version of Emacs refer to
+	lots of different variables scattered hither and yon, we'll just
+	declare this new variable, of type `struct screen', and define the
+	single-screen versions of the `SCREEN_foo' macros to reference its
+	elements.  This avoids conflicts between names of local variables
+	and names of global variables describing the screen, and simplifies
+	some of the differences between the multi-screen and single-screen
+	cases.
+	* screen.h (enum output_method, struct screen): Removed these from
+	the `#ifdef MULTI_SCREEN' conditional.
+	* screen.h [not MULTI_SCREEN] (the_only_screen): extern
+	declaration for it here.
+	[not MULTI_SCREEN] (SCREEN_CURRENT_GLYPHS, SCREEN_DESIRED_GLYPHS,
+	SCREEN_TEMP_GLYPHS, SCREEN_HEIGHT, SCREEN_WIDTH,
+	SCREEN_NEW_HEIGHT, SCREEN_NEW_WIDTH, SCREEN_CURSOR_X,
+	SCREEN_CURSOR_Y, SCREEN_ROOT_WINDOW, SCREEN_INSERT_COST,
+	SCREEN_DELETE_COST, SCREEN_INSERTN_COST, SCREEN_DELETEN_COST,
+	SCREEN_MESSAGE_BUF, SCREEN_SCROLL_BOTTOM_VPOS): Macros changed to
+	refer to the_only_screen.
+	* dispnew.c [not MULTI_SCREEN] (one_screen_cursX,
+	one_screen_cursY, one_screen_current_glyphs,
+	one_screen_desired_glyphs, one_screen_temp_glyphs,
+	delayed_screen_width, delayed_screen_height): Variables
+	deleted; they're all now kept in the_only_screen.
+	* xdisp.c [not MULTI_SCREEN] (message_buf): Variable deleted; same
+	fate.
+	* term.c [not MULTI_SCREEN] (one_screen_width, one_screen_height):
+	Variables deleted; same fate.
+	* screen.h [not MULTI_SCREEN]: extern declarations for the above
+	variables removed.
+	* window.c [not MULTI_SCREEN] (root_window): Variable deleted.
+	[not MULTI_SCREEN] (init_window_once): Use SCREEN_ROOT_WINDOW to
+	refer to the root window, instead of referring to it directly.
+	* window.h [not MULTI_SCREEN] (root_window): extern declaration
+	removed.
+	* scroll.c [not MULTI_SCREEN] (insert_line_cost, delete_line_cost,
+	insert_n_lines_cost, delete_n_lines_cost): Variables deleted; same
+	fate.
+
+	* dispnew.c [not MULTI_SCREEN] (cursX, cursY): Renamed to
+	`one_screen_cursX' and `one_screen_cursY'.
+	* screen.h [not MULTI_SCREEN] (cursX, cursY, SCREEN_CURSOR_X,
+	SCREEN_CURSOR_Y): extern declarations and macros changed
+	accordingly.
+
+	* term.c [not MULTI_SCREEN] (screen_width, screen_height): Renamed
+	to `one_screen_width' and `one_screen_height', so as not to
+	conflict with local variables when referenced by the `SCREEN_foo'
+	macros.
+	* screen.h [not MULTI_SCREEN] (screen_width, screen_height):
+	extern declarations changed accordingly.
+	* termchar.h (screen_width, screen_height): extern declarations
+	deleted.  Everyone should go through the `SCREEN_foo' macros.
+	(SCREEN_WIDTH, SCREEN_HEIGHT): Changed accordingly.
+
+1992-06-25  Jim Blandy  (jimb@pogo.cs.oberlin.edu)
+
+	* callint.c (Fcall_interactively): When making a copy of the spec
+	string, cast the return value of `alloca' to `unsigned char *',
+	not `char *', to match the type of `string'.
+
+	* xselect.c (Fx_own_selection): Cast XSTRING (string)->data to a
+	char *, so it can be comfortably passed to XStoreBytes.
+
+	* filelock.c (strcpy): Declare this to return char *.
+
+1992-06-24  Jim Blandy  (jimb@pogo.cs.oberlin.edu)
+
+	* dispnew.c (current_glyphs, desired_glyphs, temp_glyphs): Renamed
+	to have the prefix `one_screen_', so that the screen macros can
+	refer to them without conflicting with local variables.
+	* screen.h [not MULTI_SCREEN] (SCREEN_CURRENT_GLYPHS,
+	SCREEN_DESIRED_GLYPHS, SCREEN_TEMP_GLYPHS): Changed accordingly.
+
+	* keyboard.c (read_key_sequence): Put the code which restarts the
+	key sequence in a `#ifdef MULTI_SCREEN' conditional.
+
+	* screen.h [not MULTI_SCREEN]: Added definitions for
+	CHECK_LIVE_SCREEN and SCREEN_FOCUS_SCREEN for the non-multi-screen
+	case.
+
+	* screen.h [not MULTI_SCREEN]: The name is
+	`SCREEN_MINIBUF_ONLY_P', not `SCREEN_IS_MINIBUF_ONLY'.
+
+	* xdisp [not MULTI_SCREEN] (Fredraw_display): Removed definition
+	here; the non-multi-screen version is already defined in
+	dispnew.c, alongside the multi-screen version.
+	(syms_of_xdisp): Don't try to defsubr Sredraw_display; it doesn't
+	exist.
+
+	* lread.c (Fread_char_exclusive): Remove this from the `#ifdef
+	HAVE_X_WINDOWS' conditional; it is appropriate in any context.
+
+	* eval.c (Fsignal): Put call to TOTALLY_UNBLOCK_INPUT under the
+	protection of a `#ifdef HAVE_X_WINDOWS' conditional.
+
+        * keyboard.c (kbd_buffer_get_event): Expect *mouse_position_hook
+	to return the timestamp as an unsigned long, not a lisp_Object.
+	This matches the change made to `struct input_event'.
+	(make_lispy_movement): Change argument TIME to an unsigned long.
+	* xterm.c (XTmouse_position): Change TIME argument to a pointer to
+	an unsigned long.
+	* termhooks.h (mouse_position_hook): Doc fix.
+	* term.c (mouse_position_hook): Doc fix.
+
+	* termhooks.h (struct input_event): If MULTI_SCREEN is defined,
+	declare the .screen element to be `struct screen *'; otherwise,
+	declare it to be `int'.  See the comment in the file for why I've
+	done this obviously wrong thing.
+
+	* print.c (printbufidx): Doc fix.
+	* xdisp.c (message_buf_print): Doc fix.
+
+	* dispextern.h (message_buf_size): Variable deleted; it's no
+	longer used, since the message buffer is always the width of the
+	screen.
+
+	* screen.h [not MULTI_SCREEN] (message_buf): Add extern
+	declaration for it here.
+	(message_buf_print): Added extern declarations here for both the
+	MULTI_SCREEN and non-MULTI_SCREEN cases.
+	* dispextern.h (message_buf, message_buf_print): Deleted extern
+	declaration for these here.  It should never be used directly; it
+	should always be used through the SCREEN_MESSAGE_BUF macro.
+
+	* dispnew.c (temp_glyphs): Added back this variable declaration;
+	screen.h and various other places referred to this; where did it
+	go?
+	* screen.h [not MULTI_SCREEN] (temp_glyphs, desired_glyphs,
+	current_glyphs): Add extern declarations for these.
+
+	* dispnew.c (cancel_my_columns): Use SCREEN_DESIRED_GLYPHS macro,
+	instead of assuming that a SCREEN_PTR is actually a pointer to
+	something; it isn't if we're not using any of the screen support.
+	Remove the variable `screen', and find the value for
+	`desired_glyphs' directly.
+	* xdisp.c (echo_area_display): Use the SCREEN_DESIRED_GLYPHS macro
+	to find screen's desired cursor position, instead of assuming that
+	a SCREEN_PTR is a pointer to something.
+	(display_mode_line): Same.
+	* window.c (Fpos_visible_in_window_p): Use the SCREEN_WIDTH macro.
+	(replace_window): Use the SCREEN_ROOT_WINDOW macro.
+	(window_loop): Use the SCREEN_WIDTH macro.
+
+	* dispnew.c (update_screen): Enclose the statement which
+	increments `downto' in a `#ifdef HAVE_X_WINDOWS' conditional.
+
+	* screen.h [MULTI_SCREEN and not MULTI_SCREEN] (FOR_EACH_SCREEN):
+	New macro.
+	* dispnew.c (window_change_signal, do_pending_window_change): Use
+	FOR_EACH_SCREEN instead of assuming that Vscreen_list exists.
+	* window.h (root_window): Added extern declaration for this.
+
+	* screen.c: Enclose the entire file in a #ifdef MULTI_SCREEN
+	conditional.
+
+
+1992-06-23  Richard Stallman  (rms@mole.gnu.ai.mit.edu)
+
+	* window.c (Fset_window_dedicated_p):
+	Replaces Fset_window_buffer_dedicated.  Second arg just t or nil.
+
+1992-06-22  Richard Stallman  (rms@mole.gnu.ai.mit.edu)
+
+	* syntax.h (SYNTAX, SYNTAX_MATCH, SYNTAX_COMSTART_FIRST, etc.)
+	Cast character to unsigned char before indexing.
+
+1992-06-19  Jim Blandy  (jimb@pogo.cs.oberlin.edu)
+
+	* xterm.c (x_wm_set_size_hint): Set size_hints.flags to indicate
+	that we are providing the base_width and base_height data.
+
+	* xfns.c (Fx_create_screen): Default the internal border width to
+	2; this matches XTerm.
+
+	* syntax.c (Fparse_partial_sexp): Doc fix.
+
+	* syntax.c (Fparse_partial_sexp): Added phony argument list to
+	comment containing the docstring for this function, so that
+	make-docfile.c will get the right arguments.
+
+	* xfns.c (x_set_name): Don't go through the X11 brouhaha to set
+	the name unless we're actually setting it to something different
+	from the current name.
+
+1992-06-18  Jim Blandy  (jimb@pogo.cs.oberlin.edu)
+
+	* eval.c (syms_of_eval): Don't forget to escape the ends of the
+	lines in the docstring for `debug-on-quit'.
+
+	* keyboard.c (Fread_key_sequence): Reversed sense of CONTINUE_ECHO
+	argument - set this_command_key_count to zero iff CONTINUE_ECHO is
+	Qnil, not iff it's non-Qnil.
+
+1992-06-17  Jim Blandy  (jimb@pogo.cs.oberlin.edu)
+	
+	* search.c: Changed to remember the object in which the last
+	search was done, so that markers from match data are placed in
+	that buffer, instead of the current buffer.
+	(search_regs_from_string): Replaced with...
+	(last_thing_searched): This is either Qnil, meaning no searching
+	has been done, Qt, meaning that the last search was done in a
+	string, or a buffer object, meaning that the last search was done
+	in that buffer.
+	(syms_of_search): Initialize and staticpro last_thing_searched.
+	(Flooking_at, search_buffer): Set last_thing_searched to the
+	current buffer.
+	(Fstring_match): Set last_thing_searched to Qt.
+	(Fmatch_data): Test last_thing_searched to see if any searching
+	has been done, and construct integers or markers in the right
+	buffer.  Abort if it's not Qt, Qnil, or a buffer.
+	(Fstore_match_data): Set last_thing_searched according to the
+	things we find in LIST.
+	
+1992-06-16  Jim Blandy  (jimb@pogo.cs.oberlin.edu)
+
+	* fns.c (Fload_average): Document the fact that this sometimes
+	returns a list of fewer than three elements, on systems which
+	don't provide 5- and 15-minute load averages.
+
+1992-06-15  Jim Blandy  (jimb@pogo.cs.oberlin.edu)
+	
+	* xterm.c (XTread_socket): If an event arrives to a screen S,
+	don't attribute them to SCREEN_FOCUS_SCREEN (S) here.  Do that
+	synchronously, when the events are dequeued.  This keeps events
+	from being accidentally routed to the wrong screen, if we
+	temporarily redirect a screen's focus.
+	* keyboard.c (kbd_buffer_store_event): If the character being
+	stuffed is a quit character, do the SCREEN_FOCUS_SCREEN
+	redirection to it here.
+	(kbd_buffer_get_event): And do it here, before returning the
+	event.
+	
+	* eval.c (Finteractive_p): This assumed that if the function in
+	the top frame of the lisp backtrace was not a Lisp_Compiled
+	object, then Finteractive_p must have an explicit frame on the top
+	of the stack, which we could skip.  It didn't bother to follow the
+	symbol function chaining, and it would break if any C code called
+	from a non-compiled function tried to call Finteractive_p anyway.
+	Changed this to actually check if the top frame's effective
+	function is the Lisp_Subr for Finteractive_p.  This also used to
+	skip any number of frames for special forms and/or Fbytecode
+	calls.  Changed this to skip an Fbytecode frame (if present),
+	followed by any number of special form frames.

+	* eval.c (struct backtrace): Doc fix.
+
+1992-06-12  Jim Blandy  (jimb@pogo.cs.oberlin.edu)
+
+	* m/hp300bsd.h (LOAD_AVE_TYPE): This is long, not double.
+	(LOAD_AVE_CVT): Adjusted as appropriate.
+
+	* fns.c: Moved lots of system-dependent preprocessor cruft
+	dealing with getting the load average to `getloadavg.c'.
+	(Fload_average): Guts moved to `getloadavg.c'.
+	* getloadavg.c: New file, containing the necessary mess to get the
+	load average on many different systems.  This file is supposed to
+	be Emacs-independent.
+	* ymakefile (obj): Add getloadavg.o to the list.
+	(getloadavg.o): Note that this depends on its source, and config.h.
+
+	* screen.c (Fdelete_screen): Typo in loop looking for new
+	last_nonminibuf_screen - change	`screen = XCONS (screens)->cdr`
+                                     to	`screens = XCONS (screens)->cdr`
+
+	* xdisp.c (echo_area_display): Don't neglect to draw all the lines
+	of the minibuffer window (or echo area) when a message is being
+	displayed.  If the minibuffer is more than one line high, they
+	should all be blanked.
+
+1992-06-10  Jim Blandy  (jimb@wookumz.gnu.ai.mit.edu)
+
+	* sysdep.c [POSIX_SIGNALS] (sys_signal): Fix typo - rather than
+	calling new_action as if it were a function, call sigaction.
+
+1992-06-09  Richard Stallman  (rms@mole.gnu.ai.mit.edu)
+
+	* lisp.h (Qnumberp, Qnumber_or_marker_p): Declared.
+
+	* eval.c (wants_debugger): Changed NULL to NILP.
+	Who installed these calls to NULL?
+
+1992-06-09  Jim Blandy  (jimb@pogo.cs.oberlin.edu)
+
+	* dispnew.c (Fsit_for): Don't forget to actually set sec from ARG.
+
+	* termhooks.h (struct input_event): Doc fix - for mouse clicks, .x
+	and .y give the position in characters, not in pixels.
+
+	* keyboard.c (format_modifiers): Order the modifier letters
+	alphabetically - control, meta, shift, and up.
+
+1992-06-08  Richard Stallman  (rms@mole.gnu.ai.mit.edu)
+

+1992-06-08  Jim Blandy  (jimb@pogo.cs.oberlin.edu)
+
+	* window.c (Fcoordinates_in_window_p): Docstring fix.
+
+	* buffer.c (Fother_buffer): Put a comma between arguments BUFFER
+	and VISIBLE_OK in the argument list.  Duh.
+
+	* screen.c (Fdelete_screen): Remember that s is a SCREEN_PTR *,
+	not a Lisp_Object.
+
+	* search.c (search_regs): Doc fix.
+	(compile_pattern): Take a new argument - the search register
+	structure - so we can reassure the regex routines that the
+	registers have been allocated.
+	(Flooking_at, Fstring_match, search_buffer): Changed to pass
+	&search_regs to compile_pattern.
+	(search_buffer): When we've searched for a literal string and
+	found it, make sure that the search registers are allocated before
+	stuffing the location of the search into them.
+	(Fstore_match_data): If we need to allocate more registers,
+	allocate them using re_set_registers, instead of just storing the
+	new registers and hoping that regex doesn't free them.
+
+	* search.c (Freplace_match): Doc fix.
+
+1992-06-07  Richard Stallman  (rms@mole.gnu.ai.mit.edu)
+
+	* screen.c (Fdeiconify_screen): Function deleted.
+	It was the same as make-screen-visible.

+1992-06-06  Richard Stallman  (rms@mole.gnu.ai.mit.edu)
+
+	* keyboard.c: Doc fix.
+
+	* floatfns.c (Fcbrt): Renamed from Fcube_root, and #if 0'd.

+
+1992-06-05  Joseph Arceneaux  (jla@churchy.gnu.ai.mit.edu)
+
+	* config.h.in: Undefine REL_ALLOC if a system specific file
+	defines SYSTEM_MALLOC.
+
+	* sysdep.c (save_signal_handlers): Cast result of signal  to
+	avoid compiler warning.
+	* process.c (send_process): Likewise.
+
+1992-06-05  Richard Stallman  (rms@mole.gnu.ai.mit.edu)
+	
+	* keyboard.c (Fread_key_sequence): New 2nd arg CONTINUE_ECHO
+	added for the sake of universal-argument.
+	
+1992-06-04  Richard Stallman  (rms@mole.gnu.ai.mit.edu)

+1992-06-04  Roland McGrath  (roland@geech.gnu.ai.mit.edu)
+
+	* eval.c (stack_trace_on_error, debug_on_error): Made Lisp_Objects V*.
+	(syms_of_eval): Changed DEFVAR_BOOLs to DEFVAR_LISPs.
+	(wants_debugger): New fn.
+	(find_handler_clause): Use it to look in debug-on-error and
+	stack-trace-on-error lists.
+
+1992-06-04  Richard Stallman  (rms@mole.gnu.ai.mit.edu)
+
+	* floatfns.c (Fbessel_*, Ferf, Ferfc, Flog_gamma): Turned off;

+	* lread.c (Feval_buffer): Don't read any arguments, if interactive.
+
+1992-06-02  Jim Blandy  (jimb@wookumz.gnu.ai.mit.edu)
+
+	* screen.c (make_screen_without_minibuffer): Apply XSCREEN to
+	Vdefault_minibuffer_screen before calling SCREEN_LIVE_P.  The
+	argument to SCREEN_LIVE_P must be a SCREEN_PTR, not a Lisp_Object.
+
+	* dispnew.c (Fsit_for): This used to compare arg with 0 and return
+	Qt immediately.  It should actually call sit_for anyway, because
+	sit_for needs to test for input and do the redisplay.
+	(sit_for): Compare sec and usec with zero here, after we've
+	looked for input and done a redisplay.
+
+	* lread.c (Feval_buffer): Use NILP, not NIL_P.
+
+1992-06-01  Joseph Arceneaux  (jla@churchy.gnu.ai.mit.edu)
+
+	* buffer.h: New macro, BUF_SET_PT.
+
+	* lread.c: New subr `eval-buffer', replaces `eval-current-buffer',
+	which is now defined in simple.el.

+1992-05-30  Jim Blandy  (jimb@pogo.cs.oberlin.edu)
+
+	* screen.c (Fdelete_screen): If we're deleting the default
+	minibuffer screen, try to find another minibuffer screen.
+
+1992-05-29  Jim Blandy  (jimb@pogo.cs.oberlin.edu)
+
+	* buffer.c (Fother_buffer): New optional argument VISIBLE_OK,
+	indicating that buffers currently visible in windows should not be
+	discriminated against.
+
+1992-05-28  Ken Raeburn  (raeburn@cygnus.com)
+	
+	* screen.c (Fdelete_screen): Fix bugs in walking screen list.
+	(make_screen_without_minibuffer): Signal an error if the default
+	minibuffer screen is dead.
+	
+	* xfns.c (x_set_name): Use ICCCM-conforming scheme for changing
+	window name in X11.
+	(Fx_create_screen): Likewise.
+
+1992-05-27  Jim Blandy  (jimb@pogo.cs.oberlin.edu)
+
+	* xselect.c: Support getting and setting the obsolete X cut
+	buffers.
+	(Qcut_buffer0): New atom, denoting the X cut buffer 0.
+	(syms_of_xselect): Initialize and staticpro it.
+	(Fx_own_selection): If TYPE is Qcut_buffer0, interpret this to
+	mean that we should set cut buffer 0 to STRING.
+	(Fx_selection_value): If TYPE is Qcut_buffer0, interpret this to
+	mean that we should retrieve the value of cut buffer 0.
+
+1992-05-21  Jim Blandy  (jimb@pogo.cs.oberlin.edu)
+
+	* xterm.c (construct_mouse_click): Removed extra assignment of
+	result->timestamp.
+
+	* keyboard.c (last_event_timestamp): Doc fix.
+	* xselect.c (last_event_timestamp): Declare it extern here.
+	(mouse_timestamp): Variable deleted.  last_event_timestamp is a
+	more accurate thing to use here.
+	(own_selection, get_selection_value): Use last_event_timestamp
+	instead of mouse_timestamp.
+	* keyboard.c (make_lispy_event): Pass the event's timestamp
+	through the make_number function, to assure that it is properly
+	tagged before incorporating it into the lispy event.
+	* xterm.c (construct_mouse_click): The timestamp element of a
+	struct input_event is no longer a Lisp_Object; it is now an
+	unsigned long.  So don't use XSET to assign to it.
+	(XTread_socket): Same here, in processing KeyPress events.
+
+	* keyboard.c (Fexecute_extended_command): Properly initialize
+	this_command_keys to the concatenation of the sequence that
+	invoked Fexecute_extended_command, the characters making up the
+	name of the command we're running, and a return character.
+	Previously, this code would set it to the last key typed while
+	reading the function name from the minibuffer, followed by the
+	name of the function being run.
+
+1992-05-20  Jim Blandy  (jimb@pogo.cs.oberlin.edu)
+
+	* xterm.c (x_display_box_cursor): Draw the cursor at curs_{x,y},
+	rather than at s->cursor_{x,y}.  If cursor_in_echo_area is set,
+	then s->cursor_{x,y} does not accurately describe the position of
+	the cursor.  However, if we're not updating, then curs_{x,y} are
+	garbage; set them from s->cursor_{x,y}.
+
+	* dispnew.c (update_screen): Check current_screen->enable and
+	current_screen_used to see if there is any text on the last line,
+	not desired_screen->{enable,used}.  When the line isn't enabled,
+	move to line SCREEN_HEIGHT (s) - 1, not SCREEN_HEIGHT (s).
+	Rearranged conditionals.
+
+	* dispnew.c (cursor_in_echo_area): Document the interpretations of
+	positive and negative values of this variable.
+
+1992-05-18  Richard Stallman  (rms@mole.gnu.ai.mit.edu)
+
+	* dispnew.c (Fding): If have arg, don't end a keyboard macro.
+
+1992-05-18  Jim Blandy  (jimb@pogo.cs.oberlin.edu)
+
+	* dispnew.c (sit_for): New function, which is a slight
+	generalization of Fsit_for; you can tell it that it's waiting for
+	input, so C-g gets handled properly.
+	(Fsit_for): Call it, instead of replicating all its guts.
+	* keyboard.c (read_char): Call sit_for instead of Fsit_for, and
+	indicate that we're awaiting keyboard input.
+
+	* dispnew.c (Fsit_for): Rename arguments to match docstring.  Use
+	NILP instead of EQ (foo, Qnil).	 If nodisp is non-nil, call
+	wait_reading_process_input with do_display 0, instead of 1; this
+	will inhibit spurious redisplays when process input arrives during
+	a sit-for.
+
+        * process.c (Faccept_process_output): Pass zero as read_kbd
+	argument to wait_reading_process_input when PROC is nil, not when
+	PROC is non-nil.
+
+	* process.c (wait_reading_process_input): Declare read_kbd to be a
+	Lisp_Object, and use the tagging to tell the difference between a
+	process object and an integer.
+	* dispnew.c (Fsleep_for, Fsit_for, Fsleep_for_millisecs): Pass
+	read_kbd argument to wait_reading_process_input as a Lisp_Object.
+	* keyboard.c (kbd_buffer_get_event): Same.
+	* process.c (Faccept_process_output, send_process): Same.
+
+	* keyboard.c (read_char): Use save_getcjmp and restore_getcjmp
+	instead of doing the bcopy explicitly.
+
+	* xterm.c (XTread_socket): When handling an EnterWindow event,
+	don't bother to check waiting_for_input.  It's not necessary.
+
+	* keyboard.c (read_char): Don't clear waiting_for_input and
+	input_available_clear_time here.
+	(quit_throw_to_read_char): It's already done here.
+
+	* keyboard.c (quit_throw_to_read_char): Use
+	clear_waiting_for_input instead of clearing waiting_for_input
+	explicitly.
+
+1992-05-18  Jim Blandy  (jimb@pogo.cs.oberlin.edu)
+
+	* keyboard.c (read_char): Call clear_waiting_for_input instead of
+	clearing waiting_for_input and input_available_clear_time
+	explicitly.
+
+1992-05-15  Jim Blandy  (jimb@pogo.cs.oberlin.edu)
+
+	* ymakefile [defined (__GNUC__) and __GNUC__ > 1]: define
+	YMF_PASS_LDFLAGS so that it can deal with an empty flags argument.
+
+	* callproc.c (Fcall_process): Under VMS, a nil INFILE argument
+	means to read from "NLA0:", not "/dev/null".
+
+	* callproc.c (Fcall_process): Use nil as the value for display
+	(the fourth argument) when nargs >= 4, not when nargs >= 3.
+
+1992-05-14  Jim Blandy  (jimb@pogo.cs.oberlin.edu)
+	
+	* termhooks.h: Change timestamp from a Lisp_Object to an unsigned
+        long.
+	* keyboard.c (kbd_buffer_store_event): We don't have to apply the
+        XINT macro to the timestamp member of the event anymore.
+
+	* process.c (wait_reading_process_output): Don't turn off polling.
+
+	* sysdep.c (setpgrp_of_tty): Pass the address of pid, not pid
+	itself.
+
+	* process.c: Deleted cpp tangle for dealing with system-dependent
+	tty handling; #included "systerm.h".
+	* systerm.h: Add some of the things that were done in process.c:
+	If titan is #defined, then we should include <sys/ttyhw.h> and
+	<sys/stream.h> along with the other SYSV pty stuff.
+	If HPUX is #defined, then EMACS_HAVE_TTY_PGRP isn't true.
+	If XENIX is #defined, then we shouldn't try to use TIOCGETC.
+	* ymakefile: Note that process.o depends on systerm.h now.
+
+1992-05-13  Richard Stallman  (rms@mole.gnu.ai.mit.edu)
+
+        * callint.c (Fprefix_numeric_value): Value 1 for symbol other than `-'.
+
+1992-05-13  Jim Blandy  (jimb@pogo.cs.oberlin.edu)
+
+	* cmds.c (Fforward_line): If the buffer is empty, don't try to see
+	if it contains a newline, and moving nowhere at eob after
+	non-newline should return 1, not 0.
+
+	* search.c (scan_buffer): Doc fix.
+
+	* buffer.c (Fbuffer_disable_undo): Accept a buffer name as an
+	argument.
+
+1992-05-12  Richard Stallman  (rms@mole.gnu.ai.mit.edu)
+
+	* fileio.c: Include config.h first thing.	
+	
+	* keyboard.c (clear_input_pending): New subroutine.
+	* process.c (wait_reading_process_input): Make C-g really quit in
+	sit-for case.
+
+        * ymakefile (LD_SWITCH_SYSTEM): Don't use -X with GCC.
+
+1992-05-12  Jim Blandy  (jimb@pogo.cs.oberlin.edu)
+
+	* eval.c (Fapply): Use indirect_function, instead of doing a dumb
+	loop.
+	* keymap.c (get_keymap_1): Same.
+	* macros.c (Fexecute_kbd_macro): Same.
+
+	* buffer.c (init_buffer_once): Don't disable undos for *scratch*
+	here.  Do it in loadup.el.
+
+	* buffer.c (init_buffer_once): Doc fix.
+
+	* doc.c (Fdocumentation): After extracting the doc string from a
+	lambda or autoload expression, don't fall through to the default
+	case and signal an invalid function error; instead, do a `break'.
+
+	* doc.c (Fdocumentation): Use EQ (x, y) instead of XSYMBOL (x) ==
+	XSYMBOL (y).
+
+	* doc.c (Fdocumentation): When decyphering a function made from
+	conses, use 'else if' for the chain of alternatives instead of
+	just 'if'.  It used to be that each alternative returned, but
+	that's not true anymore.
+
+	* alloc.c (Fgarbage_collect): Don't call truncate_undo_list on
+	buffers whose undo list is 't.
+
+	* doc.c (Fdocumentation): Renamed argument `fun1' to `function',
+	so make-docstring will list argument consistently with the
+	docstring.
+
+1992-05-11  Joseph Arceneaux  (jla@churchy.gnu.ai.mit.edu)
+
+	* xterm.h: Removed definition of `RES_CLASS'.
+
+	* xfns.c (x_get_arg): Eliminated `screen_name' parameter.  No
+	longer uses screen name as X resource search component.
+	All calls to x_get_arg changed accordingly.
+	Global variable `screen_class' and #define `SCREEN_CLASS' removed.
+
+	* xterm.c (XTread_socket): Added basic structure for handling
+	various ClientMessage events, using new global variables
+	`Xatom_wm_take_focus', `Xatom_wm_save_yourself',
+	`Xatom_wm_delete_window', `Xatom_wm_configure_denied',
+	`Xatom_wm_moved'.
+	* xfns.c: Declare these variables extern.
+	(syms_of_xfns): Initialize these variables.
+
+	* xselect.c (Fx_own_selection, Fx_selection_value): New optional
+	parameter `type', to specify the selection type.
+	(syms_of_xselect): New symbols Qprimary, Qsecondary, Qclipboard
+	initialized.

+	(indirect_function, Findirect_function): New functions.
+	(syms_of_data): Initialize Qcyclic_function_indirection, put the
+	error properties on it, and staticpro it.  Defsubr
+	Findirect_function.
+	* lisp.h (indirect_function, Findirect_function): Declare them here.
+	* callint.c (Fcall_interactively): Get symbol's function by
+	calling indirect_function, instead of just looping.
+	* doc.c (Fdocumentation): Same.
+	* eval.c (Finteractive_p, Fcommandp, do_autoload, Feval,
+	Ffuncall): Same.
+	* keyboard.c (Fcommand_execute): Same.
+
+	* data.c (Fsymbol_function): Name the argument `symbol' instead of
+	`sym', so make-docstring will list argument consistently with the
+	docstring.
+
+	* process.c (wait_reading_process_input): Make sure the screen
+	isn't garbaged (and therefore not displayed) before we enter the
+	select and start waiting for input.
+
+	* keyboard.c: #include <systime.h>.
+	* ymakefile (keyboard.o): This depends on systime.h.
+	* keyboard.c (input_available_clear_word): Replaced with
+	input_available_clear_time, which is a pointer to an EMACSTIME;
+	sometimes the time information is larger than a single word.
+	(read_char): Changed ..._word to ..._time.
+	(input_available_signal): Use the EMACS_SET_SECS_USECS macro to
+	clear *input_available_clear_time, instead of zapping a zero into
+	*input_available_clear_word.
+	(set_waiting_for_input, clear_waiting_for_input): Adjusted
+	appropriately.
+
+1992-05-10  Jim Blandy  (jimb@pogo.cs.oberlin.edu)
+
+	* editfns.c (make_buffer_string): New function.
+	* lisp.h (make_buffer_string): Declare it here.
+	* editfns.c (Fbuffer_substring): Call make_buffer_string instead
+	of writing it out.
+	(Fbuffer_string): Call make_buffer_string instead of make_string,
+	so we can deal with buffer relocations.
+	* minibuf.c (read_minibuf): Same here.
+
+1992-05-09  Jim Blandy  (jimb@pogo.cs.oberlin.edu)
+
+	* syssignal.h (sigunblock): New macro, taken from 18.58's
+	emacssignal.h file.
+	* sysdep.c (request_sigio): Use the sigunblock macro to enable
+	reciept of SIGWINCH, instead of the dysfunctional sigblockx.
+
+1992-05-08  Richard Stallman  (rms@mole.gnu.ai.mit.edu)
+
+	* search.c: Doc fix.
+
+1992-05-06  Jim Blandy  (jimb@pogo.cs.oberlin.edu)
+
+	* emacs.c (decode_env_path): If EVARNAME is zero, don't try to
+	call getenv on it.
+	* lread.c (init_lread): When we don't have an environment variable
+	to check, pass 0 instead of the empty string.
+
+	* alloc.c (Fmake_marker): Use `SIGMASKTYPE' instead of `int'.
+	Instead of calling sigsetmask twice - once to get the mask, and
+	again to restore it - call sigblock, specifying no additional
+	signals.
+
+1992-05-05  Jim Blandy  (jimb@pogo.cs.oberlin.edu)
+
+	* alloc.c: #include <syssignal.h>, for the sake of the
+	bug-catching code in Fmake_marker.
+	ymakefile: Add dependency.
+
+	* syssignal.h [not POSIX_SIGNALS] (SIGFULLMASK): New definition,
+	for symmetry with the "defined (POSIX_SIGNALS)" case.
+
+	* callproc.c (child_setup): Since we always get the environment
+	from Vprocess_environment, don't bother to take the environment
+	the subprocess should inherit as an argument anymore.
+	* process.c (create_process): Don't pass environment as a
+	variable.  Just preserve it across call to fork.
+
+1992-05-04  Jim Blandy  (jimb@pogo.cs.oberlin.edu)
+
+	* floatfns.c: #include <syssignal.h>.
+	(float_error): Use SIGEMPTYMASK instead of zero.
+	
+	* syssignal.h [POSIX_SIGNALS] (sigmask): Defined to expand to a
+	statement expression under GCC, or a function call otherwise.
+	(sigpause, sigblock, sigunblock, sigsetmask): These are now
+	K&R-compatible macros.
+	* systerm.h [POSIX_SIGNALS] (sys_sigmask): Here is the function
+	the POSIX version of sigmask calls when we're not compiling with
+	GCC.
+	* alloc.c (Fmake_marker): Undo changes of Apr 29.
+	* callproc.c (Fcall_process): Same.
+	* data.c (arith_error): Same.
+	* floatfns.c (float_error): Same.
+	* keyboard.c (gobble_input): Same.
+
+	* sysdep.c (request_sigio, unrequest_sigio)
+
+1992-04-29  Jim Blandy  (jimb@pogo.cs.oberlin.edu)
+
+	* x11term.h (CLASS): Change this from "emacs" to "Emacs"; class
+	names should always start with an upper-case letter.
+
+	* syssignal.h: Arranged cpp conditionals so that the specific
+	cases come first, generic cases last.
+
+	* syssignal.h (sigpause, sigblock, sigunblock, sigsetmask): Macros
+	removed; they require GCC, and Emacs 19 should compile without GCC.
+	(EMACS_SIGPAUSE, EMACS_SIGBLOCK, EMACS_SIGUNBLOCK,
+	EMACS_SIGSETMASK, EMACS_SIGFREE, EMACS_SIGHOLDX, EMACS_SIGBLOCKX,
+	EMACS_SIGUNBLOCKX, EMACS_SIGPAUSEX): These are new macros that
+	don't require GCC, but expand to statements.
+	* callproc.c (Fcall_process): Use new EMACS_SIG* macros from
+	syssignal.h.
+	* keyboard.c (gobble_input): Same.
+	* sysdep.c (request_sigio, unrequest_sigio): Same.
+	* x11term.h (BLOCK_INPUT, UNBLOCK_INPUT): Same.
+	* alloc.c (Fmake_marker): Same.

+	* floatfns.c (float_error): Same.
+
+1992-04-28  Jim Blandy  (jimb@pogo.cs.oberlin.edu)
+
+	* ymakefile: If we're using GCC version 2.0 or later, use "$(CC)
+	-nostdlib" as the linker.  This will allow us to find libgcc.a
+	even when GCC puts it in a really weird place.
+	(YMF_PASS_LDFLAGS): New macro.
+	(temacs): Use it.
+
+	* s/hpux.h: Doc fix.
+
+	* filelock.c (egetenv): Declare this.
+	(lock_path, SUPERLOCK_NAME, superlock_path): New variables and
+	macros.
+	(MAKE_LOCK_PATH, lock_file, unlock_file, lock_superlock): Use the
+	variables lock_path and superlock_path instead of the PATH_LOCK
+	and PATH_SUPERLOCK macros.
+	(init_filelock): New function.
+	* emacs.c (main): Call the init_filelock function.
+	* paths.h.in (PATH_SUPERLOCK): Removed.  This is now calculated
+	from PATH_LOCK or from the EMACSLOCKDIR environment variable.
+
+	* filelock.c (MAKE_LOCK_PATH): New macro.
+	(lock_file, unlock_file, Ffile_locked_p): Use it.
+
+	* syntax.c (Fmodify_syntax_entry): Note that '-' is a synonym for
+	' ' (both denote whitespace), that '\\' denotes the escape class,
+	and that '/' denotes the character-quote class.  The description
+	used to claim that '\\' denoted the character-quote class, and
+	neglected to mention '-' and '/'.
+
+	* filelock.c (lock_file): Doc fix.
+
+1992-04-27  Jim Blandy  (jimb@pogo.cs.oberlin.edu)
+
+	* callproc.c (init_callproc): Get the default Vexec_path from the
+	environment variable "EMACSPATH"; get Vdata_directory from
+	"EMACSDATA".
+
+	* ymakefile: Fix #endif and #else comments.
+
+1992-04-27  Richard Stallman  (rms at mole.gnu.ai.mit.edu)
+
+	* ymakefile (xemacs): Link xemacs to temacs if HAVE_SHM.
+
+	* ymakefile (paths.h, config.h): Never copy, always fail.
+
+	* process.c (wait_reading_process_input): Redisplay if screen_garbaged.
+	Call do_pending_window_change first.
+	Include dispextern.h.
+	* ymakefile (process.o): Added dependency.
+
+	* ymakefile (OLDXMENU_OPTIONS): New macro, used compiling oldxmenu.
+
+1992-04-25  Jim Blandy  (jimb@pogo.cs.oberlin.edu)
+
+	* ymakefile: Changed all references to LD_CMD to LINKER, for
+	compatibility with the 18.58 configuration files.
+	* s/aix3-1.h, s/sunos4shr.h: Same here.
+
+	* ymakefile: Doc fixes.
+
+	* ymakefile (CC, MAKE): Set these variables from optional macros.
+	Change all uses of `make' to ${MAKE}.
+
+	* ymakefile: use HAVE_X11 as alias for X11.
+
+	* ymakefile (LIB_GCC, GNULIB_VAR): Handle GCC 2.
+
+	* process.c (allocate_pty): Re-arranged conditionals to put the
+	system-specific-case first, and the generic case in the #else
+	section, for consistency with the rest of Emacs.
+
+	* process.c (allocate_pty): Wait until we fail to open three ptys
+	in a row before concluding that we've reached the end of the ptys.
+
+1992-04-22  Jim Blandy  (jimb@pogo.cs.oberlin.edu)
+
+	* ralloc.c: #include "getpagesize.h".
+
+	* search.c (Flooking_at): Use search_regs.num_regs instead of
+	RE_NREGS.  As of regex version 0.4, the compiler allocates the
+	registers, and may allocate more than RE_NREGS.
+	(search_buffer): Same.
+	(Freplace_match): Use search_regs.num_regs to tell how many
+	registers are valid.  Also note that if none are valid, no search
+	has been performed.
+	(match_limit): Same.
+	(Fmatch_data): Same.
+	(Fstore_match_data): If we're trying to store more registers than
+	search_regs has allocated, re-allocate them to make room.
+
+1992-04-21  Jim Blandy  (jimb@pogo.cs.oberlin.edu)
+
+
+	* callproc.c (egetenv): Declare the type of VAR.
+
+	* lisp.h: Don't undefine NULL.  There is no longer any conflict.
+
+	* lisp.h (NUMBERP): New macro.
+	* editfns.c (Fformat): Protect the sections that deal with
+	Lisp_Float objects with a "#ifdef LISP_FLOAT_TYPE".
+	* bytecode.c (Fbyte_code): Use the NUMBERP macro instead of
+	explicitly checking for the Lisp_Float tag.
+	* callint.c (Fcall_interactively): Same here.
+
+	* xrdb.c (magic_searchpath_decoder): Re-allocate string as needed,
+	rather than making it a fixed-size array.
+
+	* xfns.c (Fx_rebind_key): Don't declare modifier_list to be a
+	register variable.  It's too big, and we need the address of its
+	first element when we pass it to XRebindKeysym anyway.
+
+	* fileio.c (Fdo_auto_save): Doc fix.
+
+1992-04-20  Jim Blandy  (jimb@pogo.cs.oberlin.edu)
+
+	* search.c (search_buffer): Cast RE_EXACTN_VALUE to char, because
+	the regex-0.4 distribution says so.
+
+	* ymakefile (dired.o): This depends on regex.h.
+
+	* process.c (wait_reading_process_input): There is code here which
+	sends SIGIO to Emacs if we thought we had input available but
+	didn't get SIGIO.  If the system doesn't have SIGIO, then
+	#ifdef it out.
+
+	* print.c (Fexternal_debugging_output): Arguments were declared
+	ANSI-style - rewritten in K&R 1 fashion.
+
+	* floatfns.c (IN_FLOAT): Cast the zero in the `else' clause of the
+	conditional expression to SIGTYPE, to match the type of the
+	float_error call in the `then' clause.
+
+	* s/hpux8: #define HPUX8; this is supposed to be customary
+	procedure, and fileio.c was expecting it, but somehow it didn't
+	get defined.
+
+	* sysdep.h: Move inclusions of [AIX] <sys/hft.h>,
+	<sys/devinfo.h>, <sys/pty.h>, <unistd.h> [NEED_BSDTTY]
+	<sys/bsdtty.h>, [HPUX and HAVE_PTYS] <sys/ptyio.h>, [SYSV_PTYS]
+	<sys/tty.h>, <sys/pty.h>, and [pfa] <sys/file.h> to systerm.h;
+	also move undefinition of LLITOUT under BSD4_1 to systerm.h.
+	* systerm.h: They're here.
+
+	* xterm.c (XTcursor_to, XTclear_end_of_line): Declare to return
+	int in the function definitions as well as their declarations.
+
+1992-04-19  Jim Blandy  (jimb@pogo.cs.oberlin.edu)
+
+	* fileio.c (directory_file_name): When checking if the string ends
+	with '/', check that slen is a valid length *before* examining
+	dst[slen-1], not after.
+
+1992-04-18  Jim Blandy  (jimb@pogo.cs.oberlin.edu)
+
+	* xterm.c (x_death_handler): New function.
+	(x_error_handler): Call x_death_handler to shut down Emacs.
+	(x_term_init): Use x_death_handler to handle SIGPIPE, instead of
+	x_error_handler, which expects to be passed a display and an
+	event.
+	* process.c (send_process): This used to set a handler to
+	catch SIGPIPEs when writing to a subprocess, and then set the
+	handler to SIGDFL after writing, but this would stomp on the
+	SIGPIPE handler for for the X connection.  So restore the prevous
+	handler instead of changing to SIGDFL.
+
+1992-04-18  Richard Stallman  (rms@mole.gnu.ai.mit.edu)
+
+	* indent.c (compute_motion): Fix skipping invis lines and
+	truncation at right margin.
+
+1992-04-17  Jim Blandy  (jimb@pogo.cs.oberlin.edu)
+
+	* s/hpux.h (PTY_NAME_SPRINTF, PTY_TTY_NAME_SPRINTF): Use pty_name,
+	not ptyname. 
+	* s/rtu.h: Same.
+
+	* process.c (pty_process): Add 'int' to the declaration 'static
+	pty_processes;'.  This makes it a happy declaration even when
+	static has been #defined as the empty string.
+	* xterm.c (XTcursor_to, XTclear_end_of_line): Same.
+
+	* unexec.c (sbrk): Declare this to return void * if __STDC__ is
+	defined, or char * otherwise.
+
+	* lread.c init_lread): Re-cleaned logic.  To determine whether the
+	load path was changed before dumping, cons up a dump path and
+	compare it.  This method is more localized and accurate.
+	(initial_path): Variable removed.
+	(syms_of_lread): Don't staticpro.
+
+	* floatfns.c (float_error): Declare and define this to return
+	SIGTYPE.
+
+	* systime.h [HAVE_TIMEVAL] (EMACS_GET_TIME): Declare dummy to be a
+	real struct timezone, instead of an EMACS_TIME.  Since
+	HAVE_TIMEVAL is defined, struct timezone ought to be declared, so
+	there's no harm in passing the genuine article.
+
+	* sysdep.c [USG] (rename): Place under the protection of a new
+	preprocessor symbol, HAVE_RENAME.
+	* s/hpux.h (HAVE_RENAME): Defined.
+
+	* sysdep.c [USG] (setpriority): Declare to return int, not void.
+
+	* s/template.h: Add template section for HAVE_TERMIOS.
+
+	* term.c (cursor_to, raw_cursor_to, fatal): Do declare the types
+	of the arguments.
+
+1992-04-15  Jim Blandy  (jimb@pogo.cs.oberlin.edu)
+
+	* callint.c (Fcall_interactively): When the interactive spec is
+	a string, it may be relocated while reading the arguments.  To
+	avoid this, make a copy of the spec to refer to, instead of
+	using a pointer to the data of the spec string.
+
+	* callint.c (Fcall_interactively): When following the function
+	chain of a symbol, check for quits.
+
+1992-04-13  Jim Blandy  (jimb@pogo.cs.oberlin.edu)
+
+	* lread.c (init_lread): Make the load path default to
+	PATH_LOADSEARCH when we're not dumping (null purify-flag), and
+	PATH_DUMPLOADSEARCH when we are (not (null (purify-flag))).
+	Change from April 7th incorrectly always used PATH_DUMPLOADSEARCH.
+
+	* lread.c (init_lread): Cleaned up logic; to determine whether the
+	load path was changed before dumping, remember the initial value
+	and compare against it.
+	(initial_path): New variable to support this.
+	(syms_of_lread): staticpro initial_path.
+
+	* ymakefile: Renamed filenames like "*-dist" to "*.in".
+
+	* config.h.in: Doc fixes.
+
+1992-04-11  Jim Blandy  (jimb@pogo.cs.oberlin.edu)
+
+	* config.h-dist: Renamed to config.h.in, for consistency with
+	the installation conventions of other GNU programs.
+	* paths.h-dist: Renamed to paths.h.in.
+
+1992-04-11  David J. MacKenzie  (djm@wookumz.gnu.ai.mit.edu)
+
+	* termcap.c: Declare getenv.
+
+1992-04-08  Jim Blandy  (jimb@pogo.cs.oberlin.edu)
+
+	* Makefile: Renamed to Makefile.in; the configure script will edit
+	this to produce Makefile.
+
+1992-04-07  Jim Blandy  (jimb@pogo.cs.oberlin.edu)
+
+	* paths.h-dist (PATH_DUMPLOADSEARCH): New macro.
+	* lread.c (init_lread): If we're building an Emacs to be dumped,
+	use PATH_DUMPLOADSEARCH as the default load path, so we can
+	correctly find our lisp files.
+
+	* config.h-dist, paths.h-dist: Added "-*- C -*-" to top lines, so
+	Emacs will know that these are really C source.
+
+1992-04-03  Jim Blandy  (jimb@pogo.cs.oberlin.edu)
+
+	* search.c (syms_of_search): When allocating memory
+	searchbuf.buffer, cast the return value of malloc to unsigned char
+	*, not char *; this changed in the most recent version of the
+	regex code.
+
+1992-03-31  Jim Blandy  (jimb@pogo.cs.oberlin.edu)
+
+	* doc.c (Fdocumentation): Don't forget to end each line of the
+	docstring with "\n\".
+
+	* process.c (Fprocess_connection): Change "#ifdef 0" around this
+	function to "#if 0".
+
+	* eval.c (Flet, FletX): Signal an error if one of the let's binding
+	clauses has more than one value form, as in (let ((a 1 2)) a).
+
+	* eval.c (Ffuncall): Re-install change of March 10; I don't know
+	why it went away.
+
+	* search.c (compile_pattern): Declare the variable which holds the
+	return value of re_compile_pattern to be const, if this is ANSI C.
+
+	* alloc.c (xrealloc): Change "ese" to "else".
+
+	* crt0.c (start1) [sun_soft]: Change 'jst' to 'jsr'.  The Sun
+	assembly language manual doesn't list any 'jst' instruction, I
+	don't know of one personally, and all the analogous code
+	around it uses 'jsr'.
+
+	* crt0.c [m68k]: Merged with GNU C Library's version: added
+	conditionals for sun_68881, sun_fpa, sun_soft.
+
+	* config.h-dist: Adjusted for renaming of share-lib to etc.
+	* lread.c (read1): Same.
+	* doc.c (Fdocumentation_property, Fsnarf_documentation): Same.
+	* ymakefile: Same.
+
+1992-03-30  Jim Blandy  (jimb@pogo.cs.oberlin.edu)
+
+	* crt0.c: Merged changes from 18.58:
+	[hp9000s300]: Set flag_fpa.  Define float_loc.
+	[new hp assembler]: Double flag_fpa and flag_68881 if %d2!=0.
+	(start1): Declare to be static at the top of the file.
+	(_start): Removed static declaration in this function; since
+	everyone wants it, we'll just put it here.
+
+1992-03-20  Richard Stallman  (rms@mole.gnu.ai.mit.edu)
+
+	* fileio.c (Finsert_file_contents): Allow quitting from I/O.
+	(Fcopy_file): Likewise.
+
+1992-03-20  Jim Blandy  (jimb@pogo.cs.oberlin.edu)
+
+	* m-intel386.h (HAVE_ALLOCA): Inhibit if C_ALLOCA.
+	(LIB_STANDARD): Alternate USG value if __GNUC__ or C_ALLOCA
+
+	* alloc.c (xrealloc): If handed a NULL pointer for the block to
+	resize, malloc a new block and return that.  Not all reallocs do
+	this.
+
+	* m/elxsi.h: Doc fix.
+
+1992-03-18  Jim Blandy  (jimb@pogo.cs.oberlin.edu)
+
+	* dispnew.c (Fsleep_for): Call wait_reading_process_input, whether
+	or not we have process support; let the emulator do the work.
+	* emacs.c (fatal_error_signal, Fkill_emacs): Call
+	kill_buffer_processes even when subprocesses is not #defined; we
+	have a stub.
+
+	* process.c [not defined (subprocesses)] (Fget_buffer_process,
+	init_process, syms_of_process): New stub versions of these functions.
+	* emacs.c (main): Call init_process and syms_of_process whether or
+	not subprocesses is #defined.
+	* xdisp.c (decode_mode_spec): Call Fget_buffer_process whether or
+	not subprocesses is #defined.
+
+1992-03-17  Jim Blandy  (jimb@pogo.cs.oberlin.edu)
+
+	* keyboard.c (kbd_buffer_get_event): Call
+	wait_reading_process_input, even when subprocesses is not
+	#defined, instead of doing a whole lot of hairy SIGIO-pausing
+	stuff.
+	* dispnew.c (Fsit_for): Call wait_reading_process_input, whether
+	or not subprocesses is #defined.
+
+	* process.c (wait_reading_process_input): Since we're no longer
+	checking for exceptional conditions in the call to select, all of
+	the different ways to call select for different systems have
+	become the same; remove the #if conditionals around this.
+
+	* keyboard.c (read_char): When returning quit_char because we got
+	an interrupt signal, claim that the character came from the
+	currently selected screen.
+
+1992-03-16  Jim Blandy  (jimb@pogo.cs.oberlin.edu)
+
+	* callproc.c (Fcall_process): Doc fix.
+
+	* process.c [not defined (subprocesses)] (kill_buffer_processes):
+	New dummy version of this function.
+	* buffer.c (Fkill_buffer): Removed '#ifdef subprocesses'
+	protection from the call to kill_buffer_processes; this is safe
+	whether or not we actually have subprocesses.
+
+1992-03-14  Jim Blandy  (jimb@pogo.cs.oberlin.edu)
+
+	* m/pfa50.h: New file.
+	* process.c (create_process, process_send_signal): Added changes
+	for m/pfa50.h.
+	* sysdep.c: same.
+	* unexec.c: same.
+
+1992-03-14  Jim Blandy  (jimb@pogo.cs.oberlin.edu)
+
+	* callproc.c (child_setup): Always put the child in its own
+	process group.
+
+1992-03-13  Jim Blandy  (jimb@pogo.cs.oberlin.edu)
+
+	* mem_limits.h (POINTER): Doc fix.
+
+	* ralloc.c: Don't #include lisp.h and xterm.h; we no longer need
+	to block input in critical sections.
+	(r_alloc, r_alloc_free, r_re_alloc): Don't use BLOCK_INPUT and
+	UNBLOCK_INPUT; these are no longer needed.
+	(struct bp): Doc fix.
+
+1992-03-11  Jim Blandy  (jimb@pogo.cs.oberlin.edu)
+
+	* ralloc.c (obtain): When deciding how many pages to request, take
+	into account the amount of spare bytes at the end of the current
+	page; let get be ROUNDUP (size - already_available), instead of
+	ROUNDUP (size).
+	(relinquish): Re-organized for clarity.
+
+	* editfns.c (Fcurrent_time): Updated to return the current time's
+	seconds split into two 16-bit integers (similar to the system used
+	by file-attributes), and the milliseconds.
+
+1992-03-10  Jim Blandy  (jimb@pogo.cs.oberlin.edu)
+
+	* process.c (Faccept_process_output): Add new optional argument
+	TIMEOUT-MSECS, and return non-nil iff we actually got some input
+	from the process(es).
+	(wait_reading_process_input): Make return value indicate whether
+	we got some input from the specified process, when read_kbd is a
+	process, or from any process when read_kbd isn't particular.
+
+	* indent.c (Fmove_to_column): Pass the correct number of arguments
+	to Findent_to.
+
+	* eval.c (Ffuncall): If a subr is asking for too many arguments,
+	abort instead of printing an error message; this is an internal
+	flaw in Emacs, and the subr cannot be called.
+
+1992-03-06  Roland McGrath  (roland@geech.gnu.ai.mit.edu)
+
+	* doc.c (Fdocumentation, Fdocumentation_property): Take optional
+	new arg to not pass results thru substitute-command-keys.
+
+1992-03-05  Jim Blandy  (jimb at pogo.cs.oberlin.edu)
+
+	* unexmips.c (unexec): When setting up the data_section header,
+	calculate the size of the section as "brk - data_start," not "brk
+	- DATA_START".
+
+1992-02-23  Jim Blandy  (jimb at pogo.cs.oberlin.edu)
+
+	* fileio.c: #include "systime.h".
+	(Fcopy_file): Use the systime.h macros to copy the time to the new
+	file.
+	* ymakefile: Note that fileio.o depends on systime.h.
+
+	* ymakefile (dispnew.o): Note that this depends on systerm.h and
+	systime.h.
+	(editfns.o, xterm.o, sysdep.o): Note that this depends on
+	systime.h.
+	(emacs.o, keyboard.o, process.o, sysdep.o): Note that these depend
+	on systerm.h.
+
+	* systerm.h: Expanded to handle getting and setting terminal
+	parameters:
+	(struct emacs_tty): New structure, which consolidates all of the
+	old tty parameter structures.
+	(EMACS_GET_TTY, EMACS_SET_TTY, EMACS_TTY_TABS_OK): New macros.
+	* sysdep.c (TABS_OK): Definitions of this macro removed;
+	EMACS_TTY_TABS_OK replaces it.
+	(TERMINAL): Definitions removed; now we use struct emacs_tty.
+	[VMS] (input_chan): Renamed to...
+	(input_fd): and defined even when VMS isn't; in that case, we
+	leave it initialized to zero, which is the input tty.  This allows
+	us to use the EMACS_GET_TTY and EMACS_SET_TTY for both VMS and
+	Unix.
+	(discard_tty_input): Use struct emacs_tty and its macros instead
+	of TERMINAL.  Replace some of conditional with a call to
+	EMACS_GET_TTY.
+	(child_setup_tty): Use struct emacs_tty and its macros instead of
+	TERMINAL and conditionals.
+	(old_gtty, old_ltchars, old_tchars, old_lmode): Replaced by...
+	(old_tty): New variable.
+	(lmode): Made conditional on BSD4_1, since it's only used by the
+	BSD4_1 support code now.
+	(init_sys_modes): Define tty to be a struct emacs_tty, not a
+	TERMINAL.  Use macros to get and set parameters for VMS and
+	Unices. Set lmode, tchars, and ltchars along with the rest of the
+	tty state.
+	(tabs_safe_p): Use EMACS_GET_TTY and EMACS_TTY_TABS_OK instead of
+	conditionals.
+	(reset_sys_modes): Use EMACS_SET_TTY to restore the settings from
+	old_tty, instead of using hairy conditionals.
+
+	* sysdep.c (get_screen_size): Neatened; now each system of
+	reporting the screen size is separated from the rest.
+	
+	* systerm.h (EMACS_HAVE_TTY_PGRP, EMACS_GET_TTY_PGRP,
+	EMACS_GET_TTY_PGRP): New macros to handle setting a tty's current
+	process group.
+	* sysdep.c (setpgrp_of_tty): Use the above, instead of
+	conditionals.
+
+	* sysdep.c: #include "systerm.h".
+	#ifs that choose #include files moved from here...
+	* systerm.h: to here.
+
+	* sysdep.c [APOLLO]: We now undefine TIOCSTART not here but...
+	* systerm.h: here.
+
+	* sysdep.c [BROKEN_TIOCGETC]: We now undefine TIOCGETC not here but...
+	* systerm.h: here.
+
+	* sysdep.c [BROKEN_FIONREAD]: We now undefine FIONREAD and FASYNC
+	not here but...
+	* systerm.h: here.
+
+	* process.c (process_send_signal): Steal 18.58's version of this,
+	but incorporate the support for VMS signals.
+	    
+	* syssignal.h (EMACS_KILLPG): New macro.
+	* process.c (process_send_signal): Use it.
+	* sysdep.c (sys_suspend): Use it.
+
+	* syssignal.h (SIGCHLD): If we have SIGCLD and not SIGCHLD, define
+	SIGCHLD as an alias for SIGCLD.
+	* sysdep.c: Remove code for above.
+
+	* sysdep.c (init_baud_rate): Rather than trying to maintain the
+	illusion of an abstraction with the OSPEED and SETOSPEED macros,
+	just use conditionalized code for each terminal kind.  This is the
+	only place we ever need this functionality.
+	(OSPEED, SETOSPEED): Definitions removed.
+
+1992-02-22  Jim Blandy  (jimb at pogo.cs.oberlin.edu)
+
+	* sysdep.c: Moved definition of sigunblock macro to ...
+	* syssignal.h: Here.
+

+
+1992-02-21  Jim Blandy  (jimb at pogo.cs.oberlin.edu)
+
+	* keyboard.c (read_char): Don't clear Vquit_flag when we catch an
+	interrupt and return a quit_char; this change (Mar 21 1991) is too
+	large a change in functionality for the cleanliness it gains.
+
+	* pwd.h: Renamed to vms-pwd.h, so that we don't get it by accident
+	when we #include <pwd.h> with the `-I.' flag given to the
+	compiler.
+	* editfns.c [VMS]: Changed to include vms-pwd.h instead of pwd.h.
+	* fileio.c [VMS]: Same.
+	* filelock.c [VMS]: Same.
+	* sysdep.c [VMS]: Same.
+
+	* xrdb.c: Changed to #include "vms-pwd.h" if VMS is defined,
+	instead of including <pwd.h> unconditionally.
+
+	* window.c (Fset_window_display_table): Rearranged to make etags
+	happy.
+
+	* xterm.c (XTread_socket): Clear the meta flag from the keypress
+	event before handing it to XLookupString.
+
+1992-02-20  Jim Blandy  (jimb at pogo.cs.oberlin.edu)
+
+	* sysdep.c: No need to test #ifdef TIOCGETP before #undefing it.
+
+1992-02-19  Jim Blandy  (jimb at pogo.cs.oberlin.edu)
+
+	* systime.h: New file.
+	* dispnew.c: #include "systime.h" to get <time.h> or <sys/time.h>,
+	whichever is appropriate, instead of using a conditional.
+	(Fsleep_for, Fsit_for, Fsleep_for_millisecs): Use the systime.h
+	macros instead of HAVE_TIMEVAL conditionals.
+	* editfns.c: #include "systime.h" to get <time.h> or <sys/time.h>,
+	whichever is appropriate, instead of using a conditional.
+	* fileio.c: Same.
+	* process.c: Same.
+	* xterm.c: Same.
+	(wait_reading_process_input): Use the systime.h macros.
+	* sysdep.c: #include "systime.h" to get <time.h> or <sys/time.h>,
+	whichever is appropriate, instead of using a conditional.
+
+	* m/template.h: Add description of NO_SOCK_SIGIO.
+
+	* sysdep.c (reset_sys_modes): Doc fix.
+
+	* keyboard.c (sigfree, sigholdx, sigblockx, sigunblockx,
+	sigpausex): Definitions moved to syssignal.h.
+

+
+	* systerm.h: New file, to consolidate the system-dependent
+	terminal-handling trash.
+	* emacs.c: #include systerm.h.
+	(main): Use systerm.h macros instead of conditionals.
+	* dispnew.c: #include systerm.h.
+	(update_screen): Use EMACS_OUTQSIZE instead of the direct ioctl.
+	* keyboard.c: #include systerm.h to get the proper FIONREAD header
+	files, instead of using conditional.
+
+	* syssignal.h: Added copyright notice.
+
+	* emacssignal.h: Renamed to syssignal.h, to be like sysdep.c.
+	* data.c, keyboard.c, process.c, sysdep.c, ymakefile: Changed
+	#include directives.
+
+1992-02-15  Jim Blandy  (jimb at pogo.cs.oberlin.edu)
+
+	* m/intel386.h: Don't bother casting the argument to the signal
+	function; the SIGTYPE code in config.emacs ought to take care of
+	this.
+
+	* buffer.c (record_buffer): Doc fix.
+
+1992-02-13  Jim Blandy  (jimb at pogo.cs.oberlin.edu)
+
+	* s/iris3-6.h: #define HAVE_GETWD.
+
+1992-02-11  Jim Blandy  (jimb at pogo.cs.oberlin.edu)
+
+	* window.c (Fwindow_at): Accept position as two arguments, not a
+	cons of numbers.
+
+	* window.c (scroll_command): Undo the Jan 31 change; do set the
+	current buffer to the selected window's buffer.  A simple
+	set-buffer will make these two different.
+
+1992-02-10  Jim Blandy  (jimb at pogo.cs.oberlin.edu)
+
+	* callproc.c (Fcall_process): Clear synch_process_death and
+	synch_process_retcode to zero before forking the process.
+
+	* process.c (synch_process_death, synch_process_retcode): Don't

+	them extern here, along with synch_process_alive.
+
+	* s/hpux.h: Define CLASH_DETECTION.
+
+	* window.c (init_window_once): Don't pass any arguments to
+	make_window.
+
+	* keyboard.c (command_loop_1): Move the label directly_done out of
+	the else block to just after the else block.  This shouldn't
+	change the semantics of the code, but appears to avoid a compiler
+	bug on SCO Unix V.3.2v2.
+
+	* fileio.c (Fset_umask, Fumask): New functions.
+	(syms_of_fileio): defsubr them.
+
+	* undo.c (Fprimitive_undo): When undoing a deletion with the point
+	before the deleted text, use Finsert_before_markers so that the
+	mark will end up on the other side of the text, if it's in the
+	area at all.
+
+	* xdisp.c (redisplay): Properly compute TAB_OFFSET for compute_motion.
+
+	* keyboard.c (command_loop_1): Don't check whether cursor is at
+	edge of screen here.
+	* dispnew.c (direct_output_forward_char): Check here, and return
+	zero if it can't be done.  And compare the cursor position to the
+	window boundaries, not the screen boundaries.
+
+1992-02-05  Jim Blandy  (jimb at pogo.cs.oberlin.edu)
+
+	* screen.c (Fscreen_parameters): If the screen has a minibuffer
+	window on another screen, return the window, instead of nil.
+	(store_screen_param): If the value of the minibuffer parameter is
+	a window, try to make it the surrogate minibuffer window.
+	(Qminibuffer): New variable, to support above change.
+	(syms_of_screen): initialize and staticpro it.
+
+	* m/tad68k.h: New file.
+
+	* fileio.c (Ffile_accessible_directory_p): New function.
+	(syms_of_fileio): defsubr it.
+	* callproc.c: #include <errno.h>.
+	(child_setup):  Accept yet another argument, current_dir.
+	Don't try to report an error here if current_dir is inaccessible;
+	this function is called in a vforking process.  Just have the
+	process exit with an error code.
+	(Fcall_process): Make sure that the current directory is okay
+	here, before we fork.  Pass the current_dir argument.
+	* process.c (create_process): Same here.
+
+	* callproc.c (Fcall_process): Don't assign into args[1] when nargs
+	< 2.  Instead, use a new variable called infile.  Re-arranged
+	logic which processes the BUFFER argument.
+
+1992-02-03  Jim Blandy  (jimb at pogo.cs.oberlin.edu)
+
+	* fileio.c (Fexpand_file_name): Doc fix.
+
+	* scroll.c (line_ins_del): Since we're calculating the array from
+	end to beginning, make the indices go that way, and thus clearly
+	get the right boundary.  This used to ignore the [0] element, and
+	write in the [screen_height] element, which doesn't exist.
+
+1992-02-03  Richard Stallman  (rms at mole.ai.mit.edu)
+
+	* xdisp.c (redisplay, try_window_id): Special case for change
+	at beginning of line, if using selective display.
+
+1992-01-31  Jim Blandy  (jimb at pogo.cs.oberlin.edu)
+
+	* m/delta88k.h: Added USUAL-OPSYS information, for the
+	config.emacs script to use.
+
+	* window.c (scroll_command): Don't bother setting the current
+	buffer to the selected window's buffer; this should always already
+	be the case.  Add check just in case.
+
+	* indent.c (compute_motion): Don't pack vpos and hpos into one int;
+	use separate variables hpos/vpos and prev_hpos/prev_vpos.
+	(vmotion): Use largest int as tovpos arg to compute_motion.
+
+1992-01-30  Jim Blandy  (jimb at pogo.cs.oberlin.edu)
+
+	* window.c: #include "keyboard.h" to get the Qmode_line and
+	Qvertical_split declarations.
+	* ymakefile (window.o): Note that this depends on keyboard.h.
+
+	* callproc.c (getenv_internal): Cast the pointer to the variable's
+	value to a char *; elisp strings are unsigned char *'s.  And
+	valuelen is an int *, not an int **.
+
+	* scroll.c (do_scrolling): Document meaning of enable flag in
+	temp_screen.
+
+1992-01-30  Richard Stallman  (rms@mole.gnu.ai.mit.edu)

+
+1992-01-28  Jim Blandy  (jimb at pogo.cs.oberlin.edu)
+
+	* term.c: #include "keyboard.h", for Vfunction_key_map.
+	* keyboard.h: Declare Vfunction_key_map.
+
+	* keyboard.h: New file, for external declarations used in
+	processing keyboard input and events.
+	* lisp.h (Qmode_line, Qvertical_split, num_input_chars,
+	poll_suppress_count): Extern declarations moved to keyboard.h.
+	* keyboard.c: #include "keyboard.h".
+	(Qvscrollbar_par, Qvslider_part, Qvthumbup_part,
+	Qvthumbdown_part, Qhscrollbar_part, Qhslider_part,
+	Qhthumbleft_part, Qhthumbright_part): Moved declarations here from
+	xfns.c, so they're with the other event heading symbols.
+	* eval.c: #include "keyboard.h".
+	* ymakefile (callint.o, keyboard.o, keymap.o, xfns.o, eval.o):
+	Note that these depend on keyboard.h.
+
+	* xfns.c: The above symbols aren't here any more.  #include
+	"keyboard.h" to get them.
+	(syms_of_xfns): Don't initialize or staticpro them.
+	* keyboard.h: Added extern declarations for the above.
+	* callint.c: #include "keyboard.h".

+	* xfns.c (Vmouse_screen_part): Variable removed, no longer used.
+	(syms_of_xfns): Changed accordingly.
+
+	* xterm.c (Qmouse_moved): Variable removed, no longer used.
+	(Qmouse_click, Qscrollbar_click): Removed.  These are now event
+	types, in keyboard.c and keyboard.h; they're no longer used in
+	this way.
+	(Vmouse_window, Vmouse_screen_part): Extern declarations removed.
+	(XTread_socket): Don't assign to Vmouse_window or
+	Vmouse_screen_part.
+	(syms_of_xterm): Changed accordingly.
+
+	* keyboard.h (EVENT_HAS_PARAMETERS, EVENT_HEAD, EVENT_WINDOW,
+	EVENT_BUFFER_POSN, EVENT_SCROLLBAR_BUTTON, EVENT_WINDOW_POSN,
+	EVENT_TIMESTAMP, EVENT_HEAD_UNMODIFIED, EVENT_HEAD_KIND): New
+	macros to recognize and access events that have parameters, like
+	mouse events.
+	* keyboard.c (read_char, echo_char, Fmouse_click_p,
+	read_key_sequence): Use them.
+	* keymap.c: #include "keyboard.h".
+	(access_keymap, store_in_keymap, Fsingle_key_description): Use the
+	macros from keyboard.h.
+
+	* keyboard.c (Qevent_kind): New symbol, naming the property of an event
+	header where we put the event's type.
+	(Qfunction_key, Qmouse_click, Qscrollbar_click): New symbols, used
+	to tag different kinds of events.
+	(Qevent_unmodified): New symbol, naming the property
+	of an event header where we put an unmodified version of the event
+	header.
+	(modify_event_symbol): Take a new argument, SYMBOL_KIND, whose
+	value should be put on the Qevent_kind property of each symbol we
+	make.  Set the Qevent_unmodified property of each symbol we make.
+	(make_lispy_event): Pass the appropriate SYMBOL_KIND argument to
+	modify_event_symbol.
+	(struct event_head, head_table): New tables, to simplify the
+	initialization of some of the event heads.
+	(syms_of_keyboard): Initialize and staticpro the symbols given in
+	head_table, and put the Qevent_kind and Qevent_unmodified
+	properties on them.  Initialize all of the new symbols listed
+	above.
+
+	* keyboard.c (lispy_function_keys, lispy_mouse_names): Renamed
+	these from function_key_names and mouse_names, and moved them
+	outside of make_lispy_event, since static doesn't work on all
+	systems, and these can't be automatic.
+
+1992-01-28  Richard Stallman  (rms@mole.gnu.ai.mit.edu)
+
+	* fileio.c (Fwrite_region): Remove Alliant conditional.

+	(find_symbol_value): New function.
+	* lisp.h (find_symbol_value): Declare it.
+	* keymap.c (current_minor_maps): Use it, instead of a call to
+	Fboundp and Fsymbol_value per every minor map, for every key
+	sequence read.
+
+	* xterm.c (x_make_screen_visible): Don't raise the window.  This
+	causes the window to pop to the front every time a message
+	appears, which isn't desirable.
+
+	* screen.c (Fselect_screen, Fdelete_screen, Fset_mouse_position,
+	Fmake_screen_visible, Fmake_screen_invisible, Ficonify_screen,
+	Fdeiconify_screen, Fscreen_parameters, Fmodify_screen_parameters,
+	Fset_screen_height, Fset_screen_width, Fset_screen_size,
+	Fset_screen_position): Use SCREEN_IS_X macro instead of testing
+	for output_x_window.
+	* xfns.c (adjust_scrollbars, Fx_store_cut_buffer): Same.
+
+1992-01-25  Jim Blandy  (jimb at pogo.cs.oberlin.edu)

+	* lisp.h (Ffollchar, Fprevchar): Renamed extern declarations as above.
+	
+	* editfns.c (Ffollowing_char): Return 0 at the end of the buffer,
+	as advertised.  Doc fix.
+	(Fprevious_char): Doc fix.
+
+	* config.h-dist: Rearranged to define user parameters before

+	conditionals on the parameters.
+
+1992-01-15  Jim Blandy  (jimb at pogo.cs.oberlin.edu)
+
+	* keyboard.c (read_key_sequence): When expanding a function key
+	recognized with Vfunction_key_map, don't scan the expansion for
+	further function key sequences.
+
+	* keyboard.c (Vfunction_key_map): Real declaration moved to
+	keymap.c; this declaration made extern.
+	(syms_of_keyboard): DEFVAR and initialization of Vfunction_key_map
+	moved to keymap.c, since it should be initialized to a keymap, but
+	we don't want to rely on Qkeymap being initialized now.
+	* keymap.c (Vfunction_key_map): Variable moved here.
+	(syms_of_keymap): DEFVAR and init here.
+
+	* keymap.c (Fglobal_key_binding): Doc fix.

+
+1992-01-15  Richard Stallman  (rms at mole.gnu.ai.mit.edu)
+
+	* process.c (sigchld_handler):
+	Set synch_process_death and synch_process_retcode.
+
+1992-01-14  Jim Blandy  (jimb at pogo.cs.oberlin.edu)
+
+	* config.h-dist (SIGTYPE): New macro to help give signal handlers
+	the correct type.

+	* process.c (create_process_1, send_process_trap,
+	create_process_sigchld, sigchld_handler): Same.
+	(create_process): Declare sigchld according to SIGTYPE.  This
+	means we don't have to cast the return value of signal.
+	* keyboard.c (input_poll_signal, interrupt_signal): Declare these
+	to return SIGTYPE.
+	(kbd_buffer_store_event): Include a forward declaration for
+	interrupt_signal here.
+	* sysdep.c (struct save_signal): Say the handler returns SIGTYPE

+	(save_signal_handlers): So we don't have to cast the return value
+	from signal here.
+	(sys_suspend): Declare oldsig according to SIGTYPE.
+	(select): Declare old_trap using SIGTYPE.
+	(select_alarm, wait_for_termination_signal): Declare these to
+	return SIGTYPE.
+
+	* emacs.c: #include <termios.h>, if we have it.
+	(fatal_error_signal): If we have termios, use tcgetpgrp to get the
+	terminal's process group.
+	* process.c: If we have termios, #include <termios.h> instead of
+	<termio.h>.
+	(process_send_signal): If we have termios, use tcgetpgrp to get
+	the terminal's process group.  Have gid default to the child's
+	pid, to simplify the logic below.
+	* sysdep.c (flush_pending_output): If we are using termios, make
+	this function a no-op; since we're not in the tty's pgroup, we
+	would get a SIGTTIN.
+
+1992-01-13  Jim Blandy  (jimb at pogo.cs.oberlin.edu)
+
+	* config.h-dist: Removed MAINTAIN_ENVIRONMENT clause.

+
+	* dispnew.c (buffer_posn_from_coords): If there is a prompt in the
+	minibuffer, account for its width when computing the buffer
+	position.
+
+	* Makefile (doall): Explicitly export CC to the xmakefile.
+
+	* ymakefile: Use /* */ around comments; # confuses cpp.
+
+	* ymakefile: Note that ralloc.o depends on mem_limits.h, xterm.h,
+	and config.h.
+	Note that vm-limit.o depends on mem_limits.h.
+
+	* lread.c (read_escape): Return \a as '\007', not '\a'; the latter
+	isn't portable, and this routine would have to be revised anyway
+	to deal with anything other than ASCII.
+
+	* keymap.c (current_minor_maps): Rewritten not to use
+	function-local static variables, to accomodate DGUX.
+
+	* xterm.h (UNBLOCK_INPUT): Replace "abort ()" with "(abort (),

+
+	* xrdb.c: Include <sys/types.h>, and declare getuid to return uid_t.
+

+
+	* xterm.c (XTcursor_to): Declare it static at the function
+	definition, as well as at the top of the file.
+	(dumpglyphs): Removed declarations for buf and cp; these variables
+	are never used.
+
+	* lisp.h (NULL): Renamed to NILP, so as not to conflict with
+	<stdio.h>, and <stddef.h>.  All callers changed; all
+	#undefinitions of NULL removed.
+
+1992-01-12  Jim Blandy  (jimb at pogo.cs.oberlin.edu)
+
+	* xdisp.c (message): #ifdef NO_ARG_ARRAY, make a local block to
+	declare the explicit argument array.
+
+	* config.h-dist: Instead of reaching the machine- and
+	system-dependent files through symlinks, replace the strings 
+
+1992-01-09  Jim Blandy  (jimb at pogo.cs.oberlin.edu)
+
+	* keyboard.c (stuff_buffered_input): Don't forget to increment

+	(read_key_sequence): Changed to recognize and substitute bindings
+	in Vfunction_key_map at any point in the sequence, unless they
+	conflict with ordinary bindings.
+	(syms_of_keyboard): DEFVAR, document, and initialize
+	Vfunction_key_map.
+
+1991-12-19  Jim Blandy  (jimb at pogo.gnu.ai.mit.edu)
+
+	* keymap.c (Vminor_mode_map_alist): New variable, to support
+	keymaps for minor modes.
+	(current_minor_maps, Fminor_mode_key_binding,
+	Fcurrent_minor_mode_maps): New functions.
+	(Fkey_binding): Rewritten to scan for minor mode bindings too.
+	(syms_of_keymap): DEFVAR, document, and initialize
+	Vminor_mode_map_alist, and defsubr the new Ffunctions.
+	(describe_buffer_bindings): Describe the bindings established by
+	minor modes too.

+	(read_key_sequence): Completely rewritten to handle scanning an
+	arbitrary number of keymaps at a time.
+
+	* keyboard.c (Fread_key_sequence): GCPRO keybuf, since it can hold
+	lisp expressions while waiting for input.  Don't pass too many
+	arguments to read_key_sequence.
+	(command_loop_1): Don't pass too many arguments to read_key_sequence.
+
+	* keyboard.c (add_command_key): New function; there are several
+	places that add keys to this_command_keys, so we make one function
+	to do the work.
+	(read_char, Fexecute_extended_command): Call add_command_key
+	instead of writing out its code again.
+	(init_keyboard): Allocate this_command_keys according to
+	this_command_keys_size.

+
+	* ymakefile (etcdir): Variable removed.
+	(libsrc, archlib, sharelib): New variables, to take the place of
+	etcdir.
+
+1991-12-18  Jim Blandy  (jimb at pogo.gnu.ai.mit.edu)
+
+	* ymakefile (CFLAGS): Don't automatically include C_DEBUG_SWITCH

+1991-12-11  Jim Blandy  (jimb at pogo.gnu.ai.mit.edu)
+
+	* config.h-dist (MULTI_SCREEN): Define this automatically when

+	* callproc.c (Vdata_directory): New lisp variable, for the
+	directory containing architecture-independent data files.
+	(init_callproc): Initialize Vdata_directory from PATH_DATA, and
+	make sure it exists.  Renamed execdir to tempdir, because we use
+	it for both Vexec_directory and Vdata_directory.
+	(syms_of_callproc): Doc fix for Vexec_directory, new DEFVAR_LISP
+	for Vdata_directory.
+	* paths.h-dist (PATH_DATA): New path macro, to initialize

+	events.
+
+	* keyboard.c (kbd_buffer_get_event): Set Vlast_event_screen for
+	mouse movements, too. 
+
+1991-11-27  Jim Wilson  (wilson at wookumz.gnu.ai.mit.edu)

+
+1991-11-26  Michael I Bushnell  (mib at geech.gnu.ai.mit.edu)
+
+	* search.c: need to include sys/types.h because of recent mod to

+
+1991-11-25  Richard Stallman  (rms at mole.gnu.ai.mit.edu)
+
+	* bytecode.c: BYTE_CODE_METER and BYTE_CODE_SAFE undefined by default.

+	use in cmd_error.
+
+	* screen.c (Fscreen_pixel_size, Fset_screen_position): Doc fix.

+
+	* screen.c (read_mouse_position): Function deleted.
+	(Fread_mouse_position): Renamed to Fmouse_position, and changed to
+	use mouse_position_hook.
+	(syms_of_screen): Adjusted accordingly.
+	* xfns.c (x_read_mouse_position): Function deleted.
+
+	* screen.h (SCREENP): The non-MULTI_SCREEN case used to say this
+	was false for all objects, but it should be true for the terminal
+	screen, so make its definition the same as in the MULTI_SCREEN
+	case.
+
+	* screen.h (SCREEN_LIVE_P): New predicate.
+	(CHECK_LIVE_SCREEN): New type-checking macro.
+	(Qlive_screen_p): New error-reporting symbol.

+
+	* xfns.c (Fx_create_screen): Doc fix.
+
+	* xfns.c (Fx_create_screen): Give the screen a minibuffer if the
+	'minibuffer parameter is t or nil; nil is the default value for

+
+1991-11-14  Jim Blandy  (jimb at pogo.gnu.ai.mit.edu)
+
+	* eval.c (specbind): Check that the thing being bound is a symbol.

+	of next_screen_window.
+
+	* xdisp.c (redisplay): Don't clear out minibuffer windows in the
+	midst of the screen loop here.  That's confusing.
+	(redisplay_window): Since this needs special code to detect
+	minibuffers anyway, put it here.  And clear all the lines of a
+	multi-line minibuffer, not just the first one.
+
+1991-11-07  Jim Blandy  (jimb at pogo.gnu.ai.mit.edu)
+
+	* screen.c (Fdelete_screen): When searching Vscreen_list for a new
+	value for last_nonminibuf_screen, remember that the screens live
+	in the cars of the list, not the cdrs.
+
+	* xterm.c (x_make_screen_visible): Rearranged for clarity.
+
+	* xdisp.c (echo_area_display): Rearranged for clarity.
+
+1991-11-06  Jim Blandy  (jimb at pogo.gnu.ai.mit.edu)
+
+	* screen.c (next_screen, prev_screen): New meaning for MINI_SCREEN

+
+	* screen.c (make_minibuffer_screen): Do set has_minibuffer for

+	* xterm.c (Vglobal_minibuffer_screen): Don't declare this extern
+	here; it's never used.
+
+1991-11-05  Jim Blandy  (jimb at pogo.gnu.ai.mit.edu)
+
+	* screen.c (Fdelete_screen): Document the fact that surrogate
+	minibuffer screens may not be deleted.
+
+	* screen.h (SCREEN_MINIBUF_ONLY_P): New predicate, true iff the
+	screen's only window is a minibuffer, aka a "minibuffer screen" or
+	a "minibuffer-only" screen.
+	* dispnew.c (change_screen_size): Use it.
+	* screen.c (Fselect_screen, next_screen, prev_screen,
+	Fdelete_screen): Use it.
+	* window.c (Fdisplay_buffer): Use it.
+
+	* screen.c (next_screen, prev_screen): Make MINIBUF a lisp
+	boolean, not a C boolean.
+	(Fnext_screen, Fdelete_screen): Changed to fit.
+	* window.c (Fnext_window, Fprevious_window): Changed to fit.
+
+	* screen.c (make_screen_without_minibuffer): Error string improvement.
+
+	* screen.c (syms_of_screen): Doc grammar fix for Vemacs_iconified.
+
+	* screen.c (next_screen): Added some sanity checks, rewrote comments.
+
+	* screen.h (Vglobal_minibuffer_screen): Don't declare this.  It
+	shouldn't be used for anything but screen creation.
+	* window.c (Fminibuffer_window): Vglobal_minibuffer_screen is not
+	necessarily the screen containing the current minibuffer window.
+	Also, call choose_minibuf_window; it does much of the work here.
+	(Fnext_window): Used to insist on looping through all screens if
+	Vglobal_minibuffer_screen was non-nil.  Now includes screen's
+	minibuffer window according to MINIBUF, no matter what screen it's
+	on, and ignores Vglobal_minibuffer_screen.  Loop termination logic
+	cleaned up.  Clarified doc string.
+	(Fprev_window): Same problems as Fnext_window, above.
+	* screen.c (Vglobal_minibuffer_screen): Documentation rewritten to
+	emphasize that it is only a parameter of the creation of
+	minibufferless screens, and not an indication of where the
+	minibuffer is.
+	(prev_screen): Used to assume that Vglobal_minibuffer_screen was
+	the only minibuffer-only screen, and would enter an infinite loop
+	if Vglobal_minibuffer_screen was the only screen in the list.
+	Rewritten to fix these problems.
+	* minibuf.c (Vglobal_minibuffer_screen): Don't declare it extern
+	here; it's not used.
+
+	* editfns.c (Fmessage): Don't call Fmake_screen_visible here.
+	* xdisp.c (message, message1): Call it here, so that Emacs C
+	functions like Fy_or_n_p make the screen visible too.
+
+1991-11-04  Jim Blandy  (jimb at pogo.gnu.ai.mit.edu)
+
+	* keyboard.c (readable_events): If EVENT_QUEUES_EMPTY, we can
+	short-circuit and say no.  Otherwise, if do_mouse_tracking, we can
+	short-circuit and say yes.  These things let us scan the event
+	queue less often.
+
+	* termhooks.h (mouse_tracking_enable_hook): Replaced by...
+	(mouse_moved, mouse_position_hook): It turns out that it is
+	possible and no less efficient simply to tell Emacs if the mouse
+	has moved since last noticed, and let it ask for the current mouse
+	position; X's pointer motion hints are a cool thing.
+	* term.c (mouse_tracking_enable_hook): Replaced by...
+	(mouse_position_hook): New, simpler interface.
+	* keyboard.c (struct movement, movement_buf, movement_ptr):
+	Replaced by...
+	(mouse_moved): This flag, to be used in conjuction with
+	mouse_position_hook.
+	(EVENT_QUEUES_EMPTY): Adjusted to use mouse_moved instead of
+	movement_buf and movement_ptr.
+	(tracking_off, Ftrack_mouse): Don't call mouse_tracking_enable
+	hook.
+	(note_mouse_position): Moved to xterm.c.
+	(get_mouse_position): Replaced by mouse_position_hook.
+	(make_lispy_event): Movement event generation code moved out to a
+	separate function...
+	(make_lispy_movement): Create a mouse movement event for the
+	current mouse position.  Use mouse_position_hook instead of
+	get_mouse_position.  Added static declaration for this above...
+	(kbd_buffer_get_event): Use mouse_moved instead of movement_buf
+	and movement_ptr.  Call make_lispy_movement instead of
+	make_lispy_event.
+	(init_keyboard): Initialize do_mouse_tracking.  Don't init
+	movement_ptr and movement_buf.
+	* xterm.h (STANDARD_EVENT_SET): Add PointerMotionMask and
+	PointerMotionHintMask to the set.
+	* xterm.c (pixel_to_glyph_translation): Renamed to
+	pixel_to_glyph_coords, made static, simplified to take advantage
+	of constant-size characters, and extended to return the bounding
+	rectangle of the glyph returned.
+	(construct_mouse_click): The 'button' field of a button event is
+	the button number, not a mask; convert it to a mask before
+	frobbing x_mouse_grabbed.  Call pixel_to_glyph_coords properly.
+	(last_mouse_screen, last_mouse_glyph): New variables, to keep
+	track of when the pointer has moved to a different glyph.
+	(note_mouse_position): Moved here from keyboard.c and made static.
+	Check if the new mouse position is over a new glyph.  If it is,
+	set mouse_moved flag; otherwise, call XQueryPointer to get the
+	next motion event.
+	(XTmouse_tracking_enable): No longer needed, since pointer motion
+	hints let us implement the simpler mouse position hook.
+	(XTmouse_position): New hook.  Call XQueryPointer to get the
+	current mouse position and request notification about the next
+	mouse movement.  Clear the mouse_moved flag.
+	(pixel_to_glyph_coords, construct_mouse_click,
+	note_mouse_position, XTmouse_position): Put these all on the same
+	page.
+	(XTread_socket): case MotionNotify, call note_mouse_position with
+	the right args; don't call pixel_to_glyph_translation.
+	(x_term_init): Set mouse_position_hook instead of
+	mouse_tracking_enable_hook.
+
+1991-10-31  Jim Blandy  (jimb at pogo.gnu.ai.mit.edu)
+
+	* xdisp.c (redisplay_window): When trying to avoid starting
+	display at the end of the buffer: check that startp < ZV, not
+	startp <= ZV.
+
+1991-10-29  Jim Blandy  (jimb at pogo.gnu.ai.mit.edu)
+
+	* xterm.c (x_do_pending_expose, XTmouse_tracking_enable): Use
+	SCREEN_IS_X instead of testing output_method directly.
+
+1991-10-26  Jim Blandy  (jimb at pogo.gnu.ai.mit.edu)
+
+	* xdisp.c (redisplay): In the single-screen optimization, always
+	update the minibuffer's screen as well as the selected screen, no
+	matter what the echo_area_glyphs are.  This makes sure that
+	messages get cleared after a keystroke.
+
+1991-10-25  Jim Blandy  (jimb at pogo.gnu.ai.mit.edu)
+
+	* callint.c (Finteractive): Doc fix.
+
+	* xterm.c (XTmouse_tracking_enable): Block input while changing
+	the screens' input selection masks.
+
+	* window.c (change_window_height): If the window being resized is
+	the only window of the screen, no size change is possible; make
+	the delta be zero.  Exit without "changing" the sizes of any
+	windows if the delta is zero.
+
+	* alloc.c: Don't bother to include xterm.h.
+	(Fgarbage_collect): Don't bother to BLOCK_INPUT here,
+	since we don't cons in the input handler.
+
+1991-10-21  Jim Blandy  (jimb at pogo.gnu.ai.mit.edu)
+
+	* window.c (init_window_once): Set last_nonminibuf_screen to the
+	initial terminal screen, so that poor Fdisplay_buffer doesn't try
+	to create a new screen on a terminal.
+
+1991-10-19  Richard Stallman  (rms@mole.gnu.ai.mit.edu)
+
+	* m-intel386.h (signal): Optionally don't define it.
+	* s-isc2-2.h (DONT_DEFINE_SIGNAL): Define this.
+
+1991-10-18  Jim Blandy  (jimb at pogo.gnu.ai.mit.edu)
+
+	* scroll.c (line_ins_del): Don't calculate costs off the end of mf
+	and ov; use < in loop condition, not <=.
+
+	* scroll.c (scroll_cost): Logic rearranged.
+
+	* dispnew.c (change_screen_size): Change "SCREEN_IS_TERMCAP
+	(screen) == output_termap" to "SCREEN_IS_TERMCAP (screen)"
+	(window_change_signal): Use SCREEN_IS_TERMCAP predicate instead of
+	testing output_method_directly.
+
+1991-10-15  Jim Blandy  (jimb at pogo.gnu.ai.mit.edu)
+
+	* xterm.h (STANDARD_EVENT_SET): Include ButtonReleaseMask in
+	STANDARD_EVENT_SET.
+	* xterm.c (XTmouse_tracking_enable): Don't bother or'ing
+	ButtonReleaseMask with the STANDARD_EVENT_SET.
+
+	* dispnew.c (buffer_posn_from_coords): If the coordinates are off
+	past the end of a line, return them as being *before* the newline,
+	not after.
+
+	* keyboard.c (kbd_buffer_get_event): Set input_pending after
+	reading the event, no matter what sort of event it is - i.e., move
+	the assignment to input_pending outside of the event lispifying
+	conditional.
+
+	* keyboard.c (note_mouse_position): Don't record a "new" mouse
+	position unless it really differs from the last one returned.
+
+	* keyboard.c (kbd_buffer_read_char): Renamed to
+	kbd_buffer_get_event, for consistency with kbd_buffer_store_event.
+
+	* window.c (Fwindow_at): modified to take the coordinates as a
+	pair, not a two-element list, for ease of use and compatibility
+	with events.  Make SCREEN argument second and optional.
+	(Fcoordinates_in_window_p): Modified to take and return the
+	coordinates as above, and to distinguish the right border as well
+	as the mode line.
+	(window_from_coordinates): Modified to distinguish the right
+	border as well as the mode line.
+	* lisp.h (Qmode_line, Qvertical_split): Declare this extern, from
+	keyboard.c.
+	* keyboard.c (make_lispy_event): Distinguish a window's right
+	border from its text area.
+
+	* window.c (coordinates_in_window): Make it static.
+
+	* window.c (Flocate_window_from_coordinates): Renamed to
+        Fwindow_at.
+	(syms_of_window): Adjusted.

+	(syms_of_screen): Adjusted.
+	* window.c (Fcoordinates_in_window_p, window_from_coordinates,
+	Flocate_window_from_coordinates): Here they are.
+	(syms_of_window): Adjusted.
+	* lisp.h: Adjusted to say so.
+
+1991-10-14  Jim Blandy  (jimb at pogo.gnu.ai.mit.edu)
+
+	* xterm.c (XTclear_end_of_line): This used to try to get the
+	cursor out of the way by comparing the line being cleared with
+	s->cursor_y, which is meaningless; it should have compared it with
+	s->phys_cursor_y.  Changed to just mark the cursor as cleared if
+	it's in the area we're clearing.
+
+1991-10-13  Richard Stallman  (rms at mole.gnu.ai.mit.edu)
+
+	* m-intel386.h: Fix typo in #endif.
+
+1991-10-12  Jim Blandy  (jimb at pogo.gnu.ai.mit.edu)
+
+	* callint.c (Fcall_interactively): Added new interactive spec 'K',
+	for mouse clicks.  Added explanation to doc string.  Removed 'e'
+	spec, which didn't work with the new input model anyway.
+	* keyboard.c (Fmouse_click_p): New function.
+	(syms_of_keyboard): defsubr it.
+
+	* keyboard.c (EVENT_QUEUES_EMPTY): Clarified comment.
+	(tracking_off): Change "if (!readable_events)" to
+	"if (!readable_events ())".
+	(Ftrack_mouse): Doc fix.
+	(kbd_buffer_read_char): Fix brainos in tossing of unwanted events.
+	Don't use EVENT_QUEUES_EMPTY to set input_pending; call
+	readable_events.
+
+1991-10-11  Jim Blandy  (jimb at pogo.gnu.ai.mit.edu)
+
+	* keyboard.c (Qmode_line): New quoted symbol.
+	(syms_of_keyboard): Initialize and staticpro it.
+	(make_lispy_event): Use it to indicate when a mouse position is in
+	a window's mode line.
+
+	* xterm.c (XTread_socket): Consider the window to be resized if
+	either the character or pixel dimensions have changed; this will
+	catch font size changes.
+
+1991-10-08  Jim Blandy  (jimb at pogo.gnu.ai.mit.edu)
+
+	* process.c (wait_reading_process_input): Removed all the
+	exceptional condition stuff.  Emacs lacks any way to respond to
+	such a state, and selecting for it without responding to it can make
+	Emacs loop indefinitely.
+
+	* xterm.c (XTread_socket, construct_mouse_click): Make sure that
+	all enqueued events have their timestamp field set.
+	* termhooks.h (struct input_event): Doc fix.
+	* keyboard.c (last_event_timestamp): New variable.
+	(get_mouse_position, kbd_buffer_store_event,
+	kbd_buffer_read_char): Make sure to fill in Vlast_event_screen and
+	last_event_timestamp.
+	* xselect.c (mouse_timestamp): Don't use this anymore.
+	(last_event_timestamp): Use this instead.
+	(Fx_own_selection, Fx_own_clipboard, Fx_get_selection,
+	Fx_get_clipboard): Use last_event_timestamp instead of
+	mouse_timestamp.
+
+	* xdisp.c (redisplay): Don't pass extra arguments to
+	update_screen.
+
+	* keyboard.c (echo_truncate): Don't call echo here; this results
+	in extraneous echoing of characters.
+	(read_key_sequence): After calling echo_truncate, call echo_char
+	to put the character we just read into the minibuffer, if
+	appropriate.
+
+	* keyboard.c (read_key_sequence): Removed unused argument
+	no_redisplay.
+
+1991-10-01  Jim Blandy  (jimb at pogo.gnu.ai.mit.edu)
+
+	* xfns.c (x_create_screen): Initialize phys_cursor_x to -1, to
+	indicate that the screen has no displayed cursor.
+
+	* xfns.c (x_create_screen): Let InternalBorderWidth default to 1.
+
+	* xterm.c (x_display_bar_cursor): Declare this to be static void.
+
+	* xterm.c (XTupdate_begin): Don't turn off the cursor.  This makes
+	ugly flickering.  Instead, make it okay for XTins_del_lines to do
+	so:
+	* screen.h (struct screen): New field phys_cursor_glyph, keeping

+	(make_lispy_event): Re-arrange scrollbar events to put the window
+	whose scrollbar was diddled right after the identifying symbol,
+	for consistency.
+	(read_key_sequence): Let the selected screen and the location of
+	the event affect the keymap used to find its binding.
+	(Fread_key_sequence): Update docstring.
+	(syms_of_keyboard): Added DEFVAR_LISP for Vlast_event_screen.
+
+1991-07-15  Jim Blandy  (jimb@pogo.gnu.ai.mit.edu)
+
+	* screen.c (next_screen): If !mini_screen, only exclude the global
+	minibuffer screen when the minibuffer is its only window.
+	(Fnext_screen): Make the docstring clearer about what MINISCREEN
+	means.
+
+	* window.c (Fother_window): Indicate that it takes both a required
+	and optional argument, instead of just one required.
+
+1991-07-15  Roland McGrath  (roland@churchy.gnu.ai.mit.edu)
+
+	* buffer.c (Fkill_buffer): Rehacked kill-buffer-hooks to use
+	standard name kill-buffer-hook, and to use set_buffer_internal
+	instead of Fset_buffer.  Use static variable containing symbol
+	instead of intern.
+	(syms_of_buffer, init_buffer_once): Qkill_buffer_hook =
+	'kill-buffer-hook.
+
+1991-07-15  Jim Blandy  (jimb at pogo.gnu.ai.mit.edu)
+
+	* keymap.c (Fsingle_key_description): When describing a listy
+	object, take the car to find the symbol that heads it, not the cdr.
+
+	* dispnew.c (buffer_posn_from_coords): Pass col and line to
+	compute_motion in the correct order.
+
+	* keyboard.c (make_lispy_event): When calculating rows and columns
+	for mouse clicks and movement events, don't forget to subtract the
+	position of the window's top left corner before passing them to
+	buffer_posn_from_coords.
+
+	* screen.c (coordinates_in_window): Removed useless test for *y ==
+	screen_height, and screen_height variable; this would be out of
+	range of all the windows anyway.
+
+	* xdisp.c (message1): Removed code to ignore messages before X has
+	started up; this issue has hopefully been addressed by the
+	condition-case in startup.el.
+
+	* editfns.c (init_editfns): Make user_name char * instead of
+	unsigned char *, since that's what most of the usages seem to
+	want.  And when expanding ampersands in AMPERSAND_FULL_NAME mode,
+	don't try to use user_name as a string; use Vuser_name.
+
+	* minibuf.c (assoc_for_completion): New function.
+	(do_completion): Use that to check for exact match.
+
+	* minibuf.c (Ftry_completion):  Fix handling of matches aside from
+	case.  If ignoring case, and all else equal, try to preserve the
+	case of the characters in the input.
+
+	* process.c (status_notify): GCPRO tail.
+
+	* sysdep.c (creat_copy_attrs, rename_sans_version):  Always set
+	protection to O:REWD when creating file.  Added new function
+	rename_sans_version, which strips the version number from the target
+	filename, renames the temporary file to this filename,  and then
+	sets the file protection of this new file to be the same as the file
+	being edited.
+
+	* sysdep.c [VMS]: Include pwd.h from Emacs.  Use sys/file.h if GCC.
+	(F_SETFL) [VMS]: Undefine this, to control conditionals.
+	(getpwnam): Make `full' unsigned.
+	(creat_copy_attrs): Add some casts.
+	(sys_access): Change prvmask and CHECKPRIV to use bitfields.
+	Add some casts, and make dummy an unsigned short int.
+	Don't use & on constants.
+	(vmserrstr): Add a cast.
+	(sys_creat): Define va_count before this function.
+
+1991-07-14  Jim Blandy  (jimb at pogo.gnu.ai.mit.edu)
+
+	* sysdep.c (sys_sleep, input_wait_timeout): Don't use & on constant.
+	[VMS]: Include pwd.h from Emacs.  Use sys/file.h if GCC.
+	(bzero, bcopy) [VMS]: Don't take address of `length'.
+
+	* sysdep.c (sys_suspend): Cast value of `signal' to insulate from
+	changed value type in sysV.3.
+
+	* sysdep.c (child_setup_tty): Turn off erase & kill chars for BSD.
+
+	* sysdep.c (discard_tty_input): Use TIOCFLUSH on Apollo.
+	(init_sys_modes): Avoid TIOCSTART on Apollo.
+
+	* sysdep.c: If HAVE_TERMIOS is not defined, define tcgetattr in
+	terms of the TIOCGETP ioctl.
+	(init_sys_modes): Handle VSUSP, V_DSUSP if HAVE_TCATTR.
+	(discard_tty_input, init_baud_rate, child_setup_tty,
+	init_sys_modes, tabs_safe_p, reset_sys_modes):
+	Use tcgetattr, and if HAVE_TCATTR, use tcsetattr.
+
+1991-07-13  Jim Blandy  (jimb at churchy.gnu.ai.mit.edu)
+
+	* s-hpux8.h: New file.
+	* fileio.c [HPUX8]: Don't include errnet.h.
+
+	* unexhp9k800.c (unexec): Local variable i to avoid compiler bug?
+
+	* sysdep.c (insque) [WRONG_NAME_INSQUE]: New function.
+	* s-386ix.h (WRONG_NAME_INSQUE): Define it.
+
+	* xdisp.c (message_buf_print): New variable.
+	(message): Clear it here.
+	* dispextern.h: Declare it here.
+	* print.c (printchar, strout): Set it and test it here.
+
+	* keyboard.c (command_loop_1): Don't clear last_command when start
+	macro.
+
+	* keyboard.c (read_command_char): Exit at eof if noninteractive.
+
+	* indent.c (invalidate_current_column): New function.
+	* editfns.c (Fwiden, Fnarrow_to_region): Call it.
+
+	* process.c (create_process): Use O_NOCTTY whenever defined,
+	unless USG.
+
+	* process.c (Fprocess_send_eof): If using a pipe, close it.
+	(close_process_descs): Check IN and OUT for nonzeroness. 
+
+	* process.c (process_send_signal): Use interrupt chars
+	to send certain signals to the process group.
+	(TIOCGETC): Undefine this if it is not really usable.
+
+	* sysdep.c (discard_tty_input): Do nothing if read_socket_hook.
+
+	* xfns.c (x_set_mouse_color): Change the default pointer shapes to
+	be closer to xterm and emacs 18.
+
+	* xterm.c (x_focus_on_screen, x_unfocus_screen): These no longer
+	call XSetInputFocus, because I think that the X-windows ICCCM
+	says that only the window manager can do this sort of thing.
+
+	* keyboard.c (read_char): When there is an unread command
+	character, goto reread_first when this_command_key_count is zero,
+	not when it is >= 0.
+	(command_loop_1): Reset this_command_key_count only if there is no
+	prefix argument.  This makes echoing of keystrokes work correctly.
+
+1991-07-11  Jim Blandy  (jimb@geech.gnu.ai.mit.edu)
+
+	* eval.c (Finteractive_p): Changed "! XTYPE (foo) == Lisp_Bar" to
+	"XTYPE (foo) != bar".
+
+1991-07-11  Jim Blandy  (jimb at geech.gnu.ai.mit.edu)
+
+	* eval.c (apply1): Don't forget to UNGCPRO before returning.
+
+	* xterm.c (XTupdate_begin): Undisplay the cursor here; do_scrolling
+	will call XTins_del_lines when the screen matrix is inaccurate, so
+	we cannot undisplay the cursor then, but do_scrolling is always
+	called within an update.
+
+1991-07-10  David J. MacKenzie  (djm at nutrimat)
+
+	* termcap.c, tparam.c [!emacs, USG || STDC_HEADERS]: Define bcopy
+	in terms of memcpy.
+
+1991-07-09  Jim Blandy  (jimb at geech.gnu.ai.mit.edu)
+
+	* scroll.c (do_scrolling): Use correct termination condition for
+	loop that uses the glyph pointers for the deleted lines to fill in
+	the inserted lines.
+
+1991-07-08  Richard Stallman  (rms at mole.gnu.ai.mit.edu)
+
+	* editfns.c: Doc fix.
+
+1991-07-03  Jim Blandy  (jimb at pogo.gnu.ai.mit.edu)
+
+	* dispnew.c (line_hash_code): Test m->highlight[vpos], not
+	m->highlight.  All lines were getting hash codes of -1, because
+	the highlight vector was never NULL.  Golly.
+
+	* process.c (list_processes_1): Handle status of network streams.
+
+1991-07-02  Richard Stallman  (rms at mole.gnu.ai.mit.edu)
+
+	* doc.c (Fdocumentation_property):
+	Pass only strings to Fsubstitute_command_keys.
+
+1991-07-02  Jim Blandy  (jimb at geech.gnu.ai.mit.edu)
+
+	* editfns.c (init_editfns): If neither of the environment
+	variables are set, DON'T set Vuser_name to Vuser_real_name; it's
+	supposed to reflect the EFFECTIVE uid.
+	Get the full name according to Vuser_name if it differs from
+	Vuser_real_name, not if they are equal.
+	And pass Vuser_name to getpwnam in that case instead of user_name,
+	which might be 0.
+
+	* lisp.h (RETURN_UNGCPRO): New macro.
+    
+	* bytecode.c (Fbyte_code): Do not remove GC protection from the
+	stack when making a function call, because the caller is
+	responsible for protecting the arguments to a MANY-arg'ed
+	function.
+	* eval.c (Fapply): If we use funcall_args, GCPRO it.
+	And when we call Ffuncall with funcall_args, tell it the correct
+	length of funcall_args, no matter which branch allocated it.
+	(Ffuncall): Don't gcpro the arguments before calling
+	Fgarbage_collect.
+	(Feval): If we're calling a subr that takes MANY args, don't
+	UNGCPRO until after we call the subr.
+	(apply1, call0, call1, call2, call3): GCPRO the arg arrays passed
+	to Ffuncall and Fapply.
+	* callproc.c (Fcall_process, Fcall_process_region): Don't GCPRO
+	the argument array.
+	* editfns.c (Finsert, Finsert_before_markers): Don't GCPRO the
+	argument array.  Added comment about when GCPROing is not needed.
+	* mocklisp.c (Finsert_string): Don't GCPRO the argument array.
+
+	* keyboard.c (init_keyboard): Handle SIGQUIT with interrupt_signal
+	on any system that has HAVE_TERMIO, not just on USG systems.
+
+1991-07-01  Richard Stallman  (rms at mole.gnu.ai.mit.edu)
+
+	* editfns.c (init_editfns): Test that user_name isn't 0.
+
+1991-06-29  Richard Stallman  (rms at mole.gnu.ai.mit.edu)
+
+	* search.c: Doc fixes.
+
+1991-06-28  Jim Blandy  (jimb at geech.gnu.ai.mit.edu)
+
+	* keyboard.c (make_lispy_event): Let the posns of mouse clicks and
+	mouse movements be nil when window_from_coordinates returns a
+	NON-window, not when it returns a window.  Since posn is a lisp
+	object, don't call make_number when consing up the event.
+	Don't call make_number on the code member of the event.
+
+	* keyboard.c (struct movement): Make the x, y, and time members
+	Lisp_Objects, since it's easier to convert from a Lisp_Object than
+	to.
+	(note_mouse_position): Adjusted for the above.
+	(make_lispy_event): Removed code to make Lisp_Objects for those
+	members.
+
+	* xterm.c (XTread_socket): When handling LeaveNotify events,
+	remember that the focus member of the event is true when the
+	receiving window now has the focus, not when it is losing it.
+	* xfns.c (Ffocus_screen): Don't signal an error if SCREEN is
+	already the focus screen.
+
+1991-06-26  Jim Blandy  (jimb at pogo.gnu.ai.mit.edu)
+
+	* alloc.c (Fmake_rope): Use sizeof (GLYPH) instead of 2 to
+	determine how large the string should be, and changed doc string
+	to describe ropes as strings of glyphs, not just as strings of
+	character pairs.
+	(Frope_elt): Use sizeof (GLYPH) as the element size, instead of
+	assuming that the elements are two bytes.
+	* lisp.h (typedef GLYPH): Moved the definition from here...
+	* config.h (typedef GLYPH): to here, so people can elect to get
+	better performance if they don't want to use huge fonts.
+	* xterm.c (dumpglyphs): Use XDrawImageString or
+	XDrawImageString16, Depending on sizeof (GLYPH).
+	
+	* data.c (Fsetq_default): Call Fset_default to do the assignments,
+	not plain Fset.
+
+	The following changes were contributed by Jamie Zawinski
+	<jwz@lucid.com>:
+
+	* bytecode.c (Fbyte_code): BYTE_CODE_SAFE and BYTE_CODE_METER
+	options added.
+	Added Bmark, Bscan_buffer, Bset_mark to support error-checking for
+	these obsolete bytecodes.
+	Added Bunbind_all to support tail-call optimization (not yet
+	implemented).
+	Did NOT add the relative branch opcodes that were in the version
+	of bytecode.c that Jamie sent.
+	The branching bytecodes now only QUIT if they take the branch.
+	Btemp_output_buffer_show, Bforward_char, Bforward_word,
+	Bskip_chars_forward, Bskip_chars_backward, and Bforward_line
+	passed the wrong number of arguments to their subrs. 
+	Brem, Bbuffer_substring, Bdelete_region, Bnarrow_to_region,
+	Bstringeqlsign, Bstringlss, Bequal, Bnthcdr, Bmember, Bassq,
+	Bsetcar, and Bsetcdr passed arguments to the subr in the wrong
+	order.
+
+1991-06-25  Jim Blandy  (jimb at churchy.gnu.ai.mit.edu)
+
+	* doc.c (Fdocumentation): Added a QUIT test to the loop that finds
+	the symbol's function value.
+
+1991-06-24  Jim Blandy  (jimb at geech.gnu.ai.mit.edu)
+
+	* xterm.c (dumprectangle): Removed call to XFlushQueue here.
+
+	* keyboard.c (command_loop_1): Call Fselect_screen to establish
+	the new selected screen after the key sequence has been read, not
+	at the top of the loop.  This way, a key sequence will happen in
+	the screen it was typed at, or (to be more precise) the screen its
+	last character was typed at.
+
+	* keyboard.c (fast_read_one_key): Function deleted, since it had
+	been #if 0'd out a long time ago.
+	(command_loop_1): Support for fast_read_one_key removed.
+
+	* eval.c (Ffuncall): Do GCPRO the arguments, contrary to the May
+	16 change.  The convention appears to be that the MANY-arged
+	callee must protect its own arguments.
+	(Fapply): Don't protect funcall_args; they are the caller's
+	responsibility.
+	* bytecode.c (Fbyte_code): GCPRO the section of the stack *above*
+	the args to Ffuncall, since it will be protected again once
+	Ffuncall returns and therefore should stay valid.  If it is not
+	protected, string relocation may make it invalid.
+	* mocklisp.c (Finsert_string): GCPRO the arguments, since insert
+	may cause a garbage collection.
+	* editfns.c (Finsert, Finsert_before_markers): GCPRO the
+	arguments, since insert may cause a garbage collection.
+	* callproc.c (Fcall_process, Fcall_process_region): GCPRO the
+	arguments, since insert may cause a garbage collection.
+
+1991-06-20  Jim Blandy  (jimb at wookumz.gnu.ai.mit.edu)
+
+	* buffer.h (struct buffer_text, struct buffer): small change to
+	comments.
+
+	* search.c (Fmatch_beginning, Fmatch_end): Fixed doc strings to
+	indicate that non-regexp searches set these too.
+
+	* window.c (Fset_window_start): If window is not the selected
+	window, set windows_or_buffers_changed, so that redisplay will
+	know that it should redisplay the window.
+
+	* callint.c (Finteractive): Changed doc string to indicate that
+	the interactive prompts are passed through format.
+
+1991-06-20  Roland McGrath  (roland@albert.gnu.ai.mit.edu)
+
+	* buffer.c (syms_of_buffer): buffer-undo-list doc fix.
+
+1991-06-11  Roland McGrath  (roland@albert.gnu.ai.mit.edu)
+
+	* data.c (Fsetq_default): Take multiple SYM, VAL args; syntax now
+	parallel to setq.
+
+1991-05-25  Jim Blandy  (jimb at wookumz.gnu.ai.mit.edu)
+
+	* keyboard.c (kbd_buffer_read_char): Fix wait-for-input loop so
+	that we always process/toss events we don't want to return.
+
+        * screen.c (Fselect_screen): Call Ffocus_screen instead of
+	x_new_selected_screen, which doesn't exist anymore.
+
+	* xfns.c (Ffocus_screen): Declare the type of the SCREEN argument.
+
+	* xfns.c (Fx_track_pointer): Function #if 0'd out - I don't think
+	that this is a feature that we want.
+	(syms_of_xfns): Elide the defsubr for the above.
+
+	* xterm.c (x_mouse_screen, x_input_screen): Variable deleted,
+	since all we really need is x_focus_screen; all other issues are
+	the realm and responsibility of the window manager.
+	(x_new_selected_screen): Renamed to x_new_focus_screen, and
+	modified not to do thiogs inappropriate for signal handlers.
+	(XTread_socket): Change the handling of EnterNotify, LeaveNotify,
+	FocusOut and FocusIn events to use x_new_selected_screen, and
+	ditched code that deals with x_mouse_screen and x_input_screen,
+	since they don't exist anymore.
+	(x_display_bar_cursor, x_display_box_cursor): Compare s with
+	x_focus_screen to see what form the cursor should take.
+	(x_destroy_window): Don't bother with x_input_screen.
+	* xfns.c (x_mouse_screen): Removed extern declaration for this.
+	(Fx_grab_pointer): Confine the pointer to x_focus_screen, not
+	x_mouse_screen.  This is wrong, but will make emacs compile until
+	this gets fixed.
+
+1991-05-23  Jim Blandy  (jimb at pogo.gnu.ai.mit.edu)
+
+	* keyboard.c (get_input_pending): Don't use trim_events; use
+	readable_events instead.
+
+	* keyboard.c (make_lispy_event): Remove case for window_sys_event,
+	since that type of event doesn't exist anymore.
+
+	* minibuf.c (Fcompleting_read): Document the backup-n argument.
+
+	* dispnew.c (init_display): Don't declare alternate_display extern
+	here.  I can't figure out what this feature is, and it's broken.
+	* emacs.c (main): Don't test alternate_display and put its value
+	in the environment.
+
+1991-05-22  Jim Blandy  (jimb at pogo.gnu.ai.mit.edu)
+
+	* keyboard.c (struct movement): Made .used an int instead of a
+	char, since that's more likely to be stored atomically on SPARCS
+	and similar machines. 
+
+	* termhooks.h (struct input_event): Removed the window_sys_event,
+	since it's not used anywhere.  Added screen_selected event type.
+	The event handling code used to change the current buffer,
+	selected window, and selected screen out from under running lisp
+	code.  Now we wait for a more convenient time by enqueuing an
+	event.
+	* xterm.c (XTread_socket): When handling FocusIn events and
+	EnterNotify events with the focus member set, enqueue a
+	selected_screen event instead of calling x_new_selected_screen.
+	* keyboard.c (trim_events): Function deleted; it is a bad idea to
+	delete events based on the current tracking state, since tracking
+	might be re-enabled later.
+	(readable_events): New function which searches the input queue for
+	readable events.
+	(tracking_off): Call readable_events to see if we should
+	redisplay.
+	(kbd_buffer_read_char):	Toss events that we are not interested in.
+	This is a better place to do it than trim_events, since we know
+	that do_mouse_tracking will not change.  Also, handle
+	screen_selected events.
+	(new_selected_screen): New variable, holding the screen which
+	should become selected the next time through command_loop_1.
+	(syms_of_keyboard): Initialize and staticpro new_selected_screen.
+	(command_loop_1): If there is a new screen to be selected, do so.
+
+1991-05-21  Jim Blandy  (jimb@wookumz.gnu.ai.mit.edu)
+
+	* xdisp.c (message): Removed the if at the top that did not
+	display messages if the current screen was a termcap screen and a
+	window system will be used.  The change to startup.el on May 18,
+	1991 replaces this.
+
+	* ralloc.c (check_memory_limits): If the address returned by the
+	allocator is not representable in a Lisp_Object, call memory_full
+	instead of printing a very silly "warning" message.
+
+1991-05-19  Jim Blandy  (jimb at wookumz.gnu.ai.mit.edu)
+
+	* xterm.c (XTread_socket): Don't overwrite the end of the buffer
+	with function keys.
+
+	* keyboard.c (tracking_off): Update input_pending after reading
+	all the input.
+	* process.c: #include "screen.h".
+	(wait_reading_process_input): Check if any screens have been newly
+	mapped and need updating.
+	* xterm.c (XTread_socket): Don't SET_SCREEN_GARBAGED when the
+	screen is unmapped; do this when is mapped.
+	(dumprectangle): Don't dump any data for garbaged screens.
+
+1991-05-18  Jim Blandy  (jimb at pogo.gnu.ai.mit.edu)
+
+	* sysdep.c (init_sys_modes): Moved the clauses that set up
+	interrupt-driven input out of the "if running on a terminal"
+	clause, since these may need to be set up even when running on a
+	window system.
+
+1991-05-17  Jim Blandy  (jimb at pogo.gnu.ai.mit.edu)
+
+	* process.c (Fprocess_status): For network connections, return
+	Qopen and Qclosed instead of Qrun and Qexit, as documented.
+
+	* lread.c (read1): Removed code that treated numbers starting with
+	a zero as octal.
+
+1991-05-16  Jim Blandy  (jimb at geech.gnu.ai.mit.edu)
+
+	* eval.c (Ffuncall): Don't gcpro the arguments; the caller
+	protects them.
+	(Fapply): Gcpro funcall_args, if we use them.
+
+	* xterm.c (notice_mouse_movement): #if 0'd this function out.
+	(XTread_socket): #if 0 the code that fakes motion events for
+	moving in and out of windows.  Also, rearrange the MotionNotify
+	case to give character rows and columns to note_mouse_position,
+	not pixel x and y positions.  Don't deal with scrollbars here.
+	* termhooks.h (struct input_event): Removed the mouse_movement
+	event kind.
+	* keyboard.c (movement_buf): A new buffer for mouse-movement events.
+	This is hairier than you might think; see the comments for this
+	and the comments for note_mouse_position and get_mouse_position
+	for an explanation of why this is hairy.
+	(movement_ptr): Where the event handler should store new mouse
+	locations.
+	(EVENT_QUEUES_EMPTY): New macro, to be used in the places that
+	used to compare kbd_fetch_ptr to kbd_store_ptr to see if there
+	were any events available; this macro tests the mouse movement
+	buffer too.
+	(Qmouse_movement): New symbol to head mouse movement events with.
+	(trim_events): Mouse movement events are no longer in kbd_buffer,
+	so don't try to trim them.
+	(tracking_off, kbd_buffer_read_char, get_input_pending): Use
+	EVENT_QUEUES_EMPTY.
+	(get_mouse_position): New function to retrieve a mouse position
+	from the buffer properly, no matter when the event-handling signal
+	occurs.
+	(kbd_buffer_read_char): If there is something in kbd_buffer, make
+	an event for that; if there is a mouse movement, make an event for
+	that; otherwise, the while loop lied.
+	(make_lispy_event): Added code to produce mouse movement events.
+	(init_keyboard): Clear the mouse movement buffer.
+	(Qmouse_moved, Qredraw_screen, Qmapped_screen, Qunmapped_screen,
+	Qexited_window, Qexited_scrollbar): Removed extern declarations
+	for these, since they're no longer generated.
+	(syms_of_keyboard): Initialize and staticpro Qmouse_movement,
+	remove DEFVAR_LISP for Vignore_mouse_events.
+
+1991-05-14  Jim Blandy  (jimb at geech.gnu.ai.mit.edu)
+
+	* lread.c (read1): Correctly parenthesize the shift when parsing
+	octal numbers, and signal an error if we see a non-octal digit.
+
+1991-05-13  Jim Blandy  (jimb at wookumz.gnu.ai.mit.edu)
+
+	* keyboard.c (trim_events): New function, to remove uninteresting
+	events from the input queue.
+	(get_input_pending): Call trim_events before checking the queue,
+	so as not to advertise input we don't care about.
+	(Ftrack_mouse): A new function to enable mouse tracking for a
+	block of code.
+	(tracking_off): A function for unwind_protection; restore the
+	mouse tracking state to what it was outside of the track-mouse
+	(syms_of_keyboard): defsubr track-mouse.
+	(make_lispy_event): Find the window io which the click occurred
+	when processing mouse_click events, instead of trusting the window
+	tree in the signal-handling code.  Include the buffer position in
+	the click event.
+
+	* xterm.c (construct_mouse_click): Return the click's screen, not
+	its window, and don't bother updating Vmouse_window.  Calculate
+	the row and column of text-area clicks using
+	pixel_to_glyph_translation, since we know that those data
+	structures are alive in signal handlers.
+
+	* screen.c (window_from_coordinates,
+	Flocate_window_from_coordinates): Moved these to window.c, since I
+	need to be able to call them even if we don't have multi-screen
+	support.
+	(syms_of_screen): Removed defsubr for
+	Flocate_window_from_coordinates.
+	* window.c (window_from_coordinates, Flocate_window_from_coordinates):
+	Here they are.
+	(syms_of_window): Here is the defsubr.
+
+	* keyboard.c (note_mouse_position): New function to enqueue
+	mouse movement events properly.
+	(current_movement_event): New variable, to support the above.  See
+	its comment for more explanation.
+
+	* termhooks.h (struct input_event): Change the .window member to
+	.screen, make it a struct screen *, and indicate that those events
+	which used to return	windows now return screens.  It is unsafe
+	for the event reader to traverse the window structure, because it
+	can be called by a signal handler.
+
+1991-05-10  Jim Blandy  (jimb at geech.gnu.ai.mit.edu)
+
+	* keyboard.c (Vignore_mouse_events): Variable deleted.
+	(make_lispy_event): For mouse and scrollbar clicks, return the
+	position as a pair of numbers, not a list of two numbers.
+
+1991-05-09  Jim Blandy  (jimb at wookumz.gnu.ai.mit.edu)
+
+	* keyboard.c (do_mouse_tracking): Define this variable, which
+	controls whether kbd_buffer_read_char will ignore button up and
+	mouse movement events.
+        * termhooks.h: Declare do_mouse_tracking here.
+
+        * xterm.h (STANDARD_EVENT_SET): New constant, giving the event
+	mask all the windows use.
+
+	* xfns.c (Vx_send_mouse_movement_events): Removed this variable;
+	XTmouse_tracking_enable and do_mouse_tracking do its job better.
+	(syms_of_xfns): Remove the DEFVAR_LISP for the above.
+	(x_window): Don't ask for any pointer motion events or button
+	release events by default; use the unmodified STANDARD_EVENT_MASK.
+	The user will ask for them explicitly if he or she wants them.
+	And don't ask for backing store.
+
+	* xterm.c (XTmouse_tracking_enable): New function to
+	request/unrequest detailed mouse tracking information of the
+	server, and set the flag used by XTread_socket.
+	(x_term_init): Set mouse_tracking_enable_hook to
+	XTmouse_tracking_enable here.
+	(XTread_socket): Handle mouse movement events by calling
+	note_mouse_position.
+
+	* xterm.c (XTread_socket): For MapNotify events, go ahead and set
+	the screen's visible flag, so Expose events will work.  Clear the
+	iconified flag.
+
+	* editfns.c (Finsert_char): Return immediately if n <= 0, not just
+	if n < 0, so that the `while' below does not become an infinite
+	loop.
+
+	* term.c (mouse_tracking_enable_hook): Added this variable to
+	allow emacs to request that the window system start or stop
+	detailed mouse tracking.
+	* termhooks.h (mouse_tracking_enable_hook): Declare it here.
+
+	* xfns.c: Declare the functions before initializing
+	x_screen_parm_table to point to them.
+
+	* xterm.c (XTread_socket): Don't send Qmapped_screen,
+	Qunmapped_screen, Qexited_scrollbar, Qexited_window,
+	Qredraw_screen - these are not features that we want to support.
+
+1991-05-07  Jim Blandy  (jimb at pogo.gnu.ai.mit.edu)
+
+	* editfns.c (Finsert_char): Let strlen be the minimum of n and
+	256, not the maximum, so we use an n-byte buffer when n < 256, and
+	a 256-byte buffer many times when n > 256.
+
+1991-05-05  Jim Blandy  (jimb at geech.gnu.ai.mit.edu)
+
+	* keymap.c (Fkeymapp): Fixed docstring to give the right
+	definition of a keymap.
+
+1991-05-03  Richard Stallman  (rms at mole.gnu.ai.mit.edu)
+
+	* data.c (Fcompiled_function_p): New function.
+
+1991-05-03  Jim Blandy  (jimb at pogo.gnu.ai.mit.edu)
+
+	* xfns.c (struct x_screen_parm_table): New type for recording
+	information about screen parameters.
+	(x_screen_parms): New table describing the existing parameters.
+	(init_x_parm_symbols, x_set_screen_param): Use x_screen_parms
+	instead of a large switch statement.
+	(x_figure_window_size): Make the default case of the switch call
+	abort instead of signalling an error, since window_prompting's
+	value is internally generated.
+
+1991-05-01  Jim Blandy  (jimb at churchy.gnu.ai.mit.edu)
+
+	* keymap.c (describe_map_tree): GCPRO the maps variable;
+	Fkey_description calls Fmapconcat, which eventually calls
+	Ffuncall, which can garbage-collect.
+
+1991-04-28  Jim Blandy  (jimb at pogo.gnu.ai.mit.edu)
+
+	* dispnew.c (buffer_posn_from_coords): Use the information in bufp
+	to reduce the distance compute_motion must scan, when possible.
+
+1991-04-27  Jim Blandy  (jimb at pogo.gnu.ai.mit.edu)
+
+	* keyboard.c (syms_of_keyboard): Qtop_level is initialized and
+	staticpro'd in syms_of_data too.  Don't staticpro (or initialize)
+	it again here.
+
+	* macros.c (syms_of_macros): Since executing-macro and
+	executing-kbd-macro are actually the same variable, use
+	DEFVAR_LISP_NOPRO for the second one so it doesn't get staticpro'd
+	twice.
+
+	* process.c (syms_of_process): Don't staticpro or initialize Qexit
+	here, since syms_of_eval already does this and it's bad to
+	staticpro something twice.
+	(Qexit): Remove declaration here, so there will be a compilation
+	error if someone rearranges eval.c without fixing the Qexit stuff.
+	* eval.c (syms_of_eval): Add comment here to say that
+	syms_of_process cares about Qexit too.
+
+	* lread.c (init_obarray): Don't staticpro Vobarray, since the
+	DEFVAR_LISP in syms_of_read takes care of that.
+
+1991-04-22  Jim Blandy  (jimb at pogo.gnu.ai.mit.edu)
+
+	* window.c (save_window_save): Always get the selected window's
+	value of point from its buffer, not just when it's also the
+	current buffer.
+
+	* lisp.h (Qdisabled): Declare this here so that the keys_of_*
+	files can disable the commands they define.
+	* casefiddle.c (keys_of_casefiddle): Make upcase-region and
+	downcase-region disabled, by default.
+
+1991-04-16  Jim Blandy  (jimb at pogo.gnu.ai.mit.edu)
+
+	* bytecode.c (PUSH):  Alliant can't be bothered to implement the
+	preincrement operator right, so use a comma.
+
+ 	* print.c (syms_of_print): staticpro Qexternal_debugging_output.
+
+	* editfns.c (clip_to_bounds): No longer static - used in window.c.
+	* window.c (unshow_buffer): Use clip_to_bounds to make sure we
+	change point to something legal.
+
+1991-04-14  Richard Stallman  (rms at mole.gnu.ai.mit.edu)
+
+	* sysdep.c: Changes in formatting and comments.
+
+1991-04-12  Jim Blandy  (jimb at wookumz.gnu.ai.mit.edu)
+
+	* editfns.c (Fbuffer_substring): Don't call make_string, because
+	it may cause a compaction and move the buffer, and then copy the
+	wrong data.
+
+	* keyboard.c (read_char): Only GC if we've actually done enough
+	consing since the last gc to make it worthwhile.
+
+1991-04-11  Jim Blandy  (jimb at geech.gnu.ai.mit.edu)
+
+	* keymap.c (access_keymap): Canonicalize the order of the
+	modifiers when you look up a symbol in a keymap, too.
+	(where-is-internal): If the keymap in which we found the
+	definition was reached by meta-prefix-char, replace it with the
+	metized character.
+
+	* eval.c (Fcondition_case): Initialize the `handler_list' member
+	of the catchtag.
+
+	* keyboard.c (read_char): reset recent_keys_index when it is
+	greater than OR EQUAL to the number of elements in recent_keys,
+	stupid.
+
+	* keymap.c (access_keymap): When fetching the car of listy events,
+	no need to call Fcar_safe - extract the car directly.
+	* keyboard.c (read_key_sequence): Don't extract the car from listy
+	events here since 1) it strips information that we need from the
+	events, and 2) access_keymap will take care of that for us.
+
+	* macros.c (Qexecute_kbd_macro): New variable, used by
+	Fexecute_command.
+	(syms_of_macros): Initialize and staticpro Qexecute_kbd_macro.
+	* lisp.h: Add extern declaration for Qexecute_kbd_macro.
+	* keyboard.c (Fcommand_execute): Add an entry to the command
+	history for keyboard macros too.
+
+	* xterm.c (XTread_socket): If we get a MappingNotify event whose
+	request == MappingKeyboard, someone has changed the keyboard
+	mapping, and we should get the new mapping with
+	XRefreshKeyboardMapping.
+
+1991-04-10  Jim Blandy  (jimb at wookumz.gnu.ai.mit.edu)
+
+	* commands.h: Declare last_command_char to be a Lisp_Object, not
+	an integer (ack).
+
+	* cmds.c (Fself_insert_command): If last_command_char is not an
+	integer, beep.
+	* minibuf.c (Fself_insert_and_exit): Same thing.
+
+	* keyboard.c (format_modifiers): New function, factoring out code
+	from modify_event_symbol and reorder_modifiers.
+	(modify_event_symbol): Call format_modifiers instead of doing the
+	work inline.
+	(reorder_modifiers): New function to put the modifiers on a
+	modified symbol in the canonical order.
+
+	* keymap.c (modify_event_symbol): Prepend the modifiers so they
+	appear in the canonical order: `M-C-S-U-'.
+	(store_in_keymap): If IDX is a symbol, put the modifiers in the
+	canonical order before storing.
+
+1991-04-09  Jim Blandy  (jimb at pogo.gnu.ai.mit.edu)
+
+	* keymap.c (Flocal_set_key, Fglobal_set_key): When checking types
+	of arguments, allow KEYS to be a vector or string, not just a
+	string.
+	(keymap_table): New static function to replace duplicated code in
+	access_keymap and store_in_keymap.
+	(access_keymap): Use keymap_table.
+	(store_in_keymap): Use keymap_table, and put non-character
+	definitions in dense keymaps *after* the vector.
+
+	* fileio.c (directory_file_name): Remove trailing slashes from
+	single-letter names like "a/" too.  Let slen be the string length,
+	not one less than the string length.
+
+	* keyboard.c (Fset_input_mode): Don't complain that QUIT isn't an
+	ASCII character if it is nil - it is an optional parameter.
+
+	* keymap.c (Faccessible_keymaps): Use meta-characters in the key
+	sequences returned, carefully making sure that the sequences still
+	appear in order of increasing length.
+
+1991-04-04  Richard Stallman  (rms at mole.gnu.ai.mit.edu)
+
+	* vmsfns.c (vms_trnlog): Increased size of str to 256 elements.
+	(vms_symbol): Increased size of str to 1025 elements.
+
+1991-03-24  Jim Blandy  (jimb at pogo.gnu.ai.mit.edu)
+
+	* dispnew.c (pixel_to_glyph_translation): Moved this function to
+	xterm.c, since it is specific to X and only called by the X code.
+	* xterm.c (pixel_to_glyph_translation): Here it is.
+
+1991-03-22  Richard Stallman  (rms at mole.gnu.ai.mit.edu)
+
+	* s-usg5-4.h (DATA_SEG_BITS): Definition deleted.
+	* m-intel386.h (DATA_SEG_BITS): Define here if USG5_4.
+
+1991-03-22  Jim Blandy  (jimb at pogo.gnu.ai.mit.edu)
+
+	* keymap.c (Faccessible_keymaps): Produce meta-characters in the
+	key sequences instead of [meta-prefix-char CHAR] sequences.
+
+1991-03-21  Jim Blandy  (jimb at pogo.gnu.ai.mit.edu)
+
+	* keymap.c (Flookup_key): If KEY is a zero-length array, then
+	return KEYMAP; this is more algebraically satisfying.
+
+	* dispnew.c (Fsit_for): If the time to sit is zero and there is no
+	input available, then return Qt, not Qnil.
+
+	* keyboard.c (read_char): If a quit occurs and we return
+	quit_char, clear Vquit_flag, so we don't end up returning it again
+	and again...  All lisp code does this manually if they call
+	read-char with quits inhibited, so it's the right thing to do.
+
+1991-03-20  Jim Blandy  (jimb at pogo.gnu.ai.mit.edu)
+
+	* keyboard.c (read_char): If there is still no input available
+	after an auto-save, do a garbage-collection.
+
+	* undo.c (truncate_undo_list): Always leave at least one undo
+	record in the undo list.  And use sizeof (struct Lisp_Cons), etc.
+	instead of 8, etc.
+
+	* keyboard.c (read_char): When deciding whether to wrap
+	recent_keys_index back to 0, compare it against
+	sizeof (recent_keys)/sizeof(recent_keys[0]),
+	not sizeof (recent_keys).
+	(quit_char): This can't be anything but an ASCII character, so it
+	shouldn't be a Lisp_Object.  The declaration's comment says why.
+	(read_char, init_keyboard): Treat quit_char as an int now.
+	(Fset_input_mode): As above, and signal an error if QUIT is not an
+	ASCII character.
+
+	* callint.c (Fprefix_numeric_value): Use XFASTINT to initialize
+	val, not raw.
+
+	* fileio.c (Fmake_symbolic_link): Don't expand FILENAME; this
+	would make it impossible to make a link to a relative name.
+
+1991-03-19  Jim Blandy  (jimb at pogo.gnu.ai.mit.edu)
+
+	* keyboard.c (syms_of_keyboard): Removed the DEFVAR_BOOL for
+	meta-flag.  This cannot be a lisp variable because we need to
+	change the terminal settings whenever this flag changes.  Change
+	this through set-input-mode instead.
+
+1991-03-19  Richard Stallman  (rms at mole.gnu.ai.mit.edu)
+
+	* keyboard.c (read_avail_input): Raise SIGHUP if no input on AIX.
+
+1991-03-19  Jim Blandy  (jimb at churchy.ai.mit.edu)
+
+	* keyboard.c (kbd_buffer_store_event, kbd_buffer_read_char,
+	read_key_sequence, Fexecute_extended_command, Fset_input_mode,
+	init_keyboard, syms_of_keyboard): Use XSET (var, Lisp_Int, exp)
+	instead of XSETINT (var, exp) in those cases where var is not
+	known to already be a Lisp_Int.
+	* search.c (skip_chars): Same.
+	* xterm.c (construct_mouse_click, XTread_socket): Same.
+	* callint.c (Fprefix_numeric_value): Make sure to return a
+	Lisp_Int even when RAW is a cons whose car is not a Lisp_Int.
+	* process.c (sigchld_handler): When searching for a process whose
+	pid is -1, make sure that the pid is an int first, since network
+	streams are in Vprocess_alist too.
+
+	* keyboard.c (syms_of_keyboard): Added DEFVAR_BOOL for
+	meta-flag.  Emacs 18 had this, and I see no entry in the ChangeLog
+	saying that it was purposefully removed.
+
+1991-03-17  Jim Blandy  (jimb at geech.ai.mit.edu)
+
+	* keymap.c (Fcopy_keymap, Faccessible_keymaps, describe_map,
+	append_key): Minor typos and brainos corrected.
+
+	* keyboard.c (read_char): Removed code to find the vector in a
+	(kbd-macro . VECTOR) - style macro, since the macro is represented
+	by the vector itself.
+	(read_char_menu_prompt): Changed to correctly recognize the new 
+	dense keymap structures.
+	(read_key_sequence): Changed code that checks for keymapness to
+	use get_keymap_1 instead of doing the indirection and keymapness
+	testing itself.
+	(Fcommand_execute): A keyboard macro is now a string or a vector.
+	(Fexecute_extended_command): When expanding this_command_keys,
+	remember that it is now an array of Lisp_Objects, not chars.
+
+	* doc.c (Fdocumentation): Rearranged into a switch statement, and
+	made vectors macros, not keymaps.
+
+	* eval.c (Fcommandp): Removed code to recognize 
+	(kbd-macro . VECTOR) as a command, and added code to recognize
+	vectors as commands.
+	* macros.c (Qkbd_macro): Variable deleted.
+	(syms_of_macros): Initialization of Qkbd_macro removed.
+
+1991-03-14  Jim Blandy  (jimb at pogo.ai.mit.edu)
+
+	* minibuf.c (keys_of_minibuf): Changed all calls to
+	initial_define_lisp_key to calls to initial_define_key.
+
+	* keymap.c (describe_map): Adjusted to handle the new style of
+	keymap.
+
+1991-03-14  Richard Stallman  (rms at mole.ai.mit.edu)
+
+	* fileio.c (Fwrite_region): On VMS, don't try rewriting old version.
+
+1991-03-14  Jim Blandy  (jimb at pogo.ai.mit.edu)
+
+	* keymap.c (Faccessible_keymaps): Adjusted to handle the new style
+	of keymap.
+	(Fwhere_is_internal): Handle the new-style of keymaps.
+	Additionally, only check to see if a match is shadowed by a
+	binding in the local keymap when LOCAL_KEYMAP is non-nil, instead
+	of comparing elt against DEFINITION yet again.
+	(describe_map_tree): Handle key sequences that are vectors, as
+	well as those that are strings.
+
+1991-03-13  Jim Blandy  (jimb at churchy.ai.mit.edu)
+
+	* commands.h, keymap.c (meta_map, control_x_map): Make these
+	Lisp_Objects, not Lisp_Vectors.
+	keymap.c (syms_of_keymap): Same.
+
+	* keymap.c (Fuse_global_map): There is no longer any reason to
+	insist that KEYMAP must be a dense keymap; delete the code that
+	does so.
+
+1991-03-12  Jim Blandy  (jimb at wookumz.ai.mit.edu)
+
+	* commands.h, lisp.h: Changed global_map and current_global_map	to
+	be Lisp_Objects, not Lisp_Vectors.
+	keyboard.c (read_key_sequence): Same.
+	keymap.c (Fkey_binding, Fglobal_key_binding, Fglobal_set_key,
+	Fuse_global_map, Fwhere_is_internal, describe_buffer_bindings,
+	syms_of_keymap): Same.
+
+	* keymap.c (Fdefine_key): Braino: increment idx and clear metized
+	flag even when the element of the key sequence isn't a character.
+	(Flookup_key): Fix same braino.
+
+1991-03-10  Jim Blandy  (jimb at wookumz.ai.mit.edu)
+
+	* keymap.c (get_keyelt): Use access_keymap to resolve indirect
+	entries, instead of duplicating its code.
+	(Fcopy_keymap): Handle the new keymap structure.
+
+1991-03-09  Richard Stallman  (rms at mole.ai.mit.edu)
+
+	* eval.c (struct catchtag): New field handlerlist.
+	(internal_catch, internal_condition_case): Set that field.
+	(unbind_catch): Use it.
+
+1991-03-08  Richard Stallman  (rms at mole.ai.mit.edu)
+
+	* m-intel386.h (signal): Maybe define if USG.
+
+	* keyboard.c (echo_char): Don't have space at end of echobuf.
+
+1991-03-07  Jim Blandy  (jimb at albert.ai.mit.edu)
+
+	* keyboard.c (syms_of_keyboard): Initialize mouse_syms, instead of
+	doing func_key_syms twice.  Don't deal with scrollbar_syms, since
+	it doesn't exist.
+
+1991-03-06  Jim Blandy  (jimb at pogo.ai.mit.edu)
+
+	* keymap.c (access_keymap, store_in_keymap): Changed to handle the
+	new style of keymaps.
+
+	* fns.c (Fassq, Fcopy_alist): Changed docstring to promise to
+	ignore elements of LIST that are not conses.  See access_keymap
+	and copy_keymap for a cheap excuse.
+
+1991-03-06  Richard Stallman  (rms at mole.ai.mit.edu)
+
+	* s-vms.h (DATA_START): Remove `+ 512'.
+
+1991-03-05  Jim Blandy  (jimb at spiff.ai.mit.edu)
+
+	* keymap.c (Fmake_keymap): Rewritten to construct the
+	new dense keymap structure: (keymap VECTOR . ALIST).  Docstring
+	adjusted accordingly.  This means that the keyboard macro
+	stupidity (see Feb 27, keyboard.c) is no longer needed.
+
+1991-03-03  Richard Stallman  (rms at mole.ai.mit.edu)
+
+	* sysdep.c (MEMORY_IN_STRING_H): New compilation flag.
+	* s-isc2-2.h: New file.
+
+1991-02-27  Jim Blandy  (jimb at churchy.ai.mit.edu)
+
+	* macros.c (Qkbd_macro): New variable, to hold the symbol
+	`kbd-macro', which we use to tag vector-style keyboard macros.
+	(syms_of_macros): Initialize and staticpro Qkbd_macro.
+
+	* eval.c (Fcommandp): Recognize the new keyboard macros.
+
+	* keyboard.c (Fcommand_execute): A keyboard macro is now a string,
+	or a cons whose car is the symbol `kbd-macro' and whose
+	cdr is a vector of events; previously, macros were strings or
+	vectors, but that makes it difficult to tell the difference
+	between macros and dense keymaps.
+	(read_char): Handle the new macros correctly, and re-allocate
+	this_command_keys correctly.
+
+1991-02-26  Richard Stallman  (rms at mole.ai.mit.edu)
+
+	* s-vms.h (calloc): Define like malloc, etc.
+
+1991-02-26  Jim Blandy  (jimb at spiff.ai.mit.edu)
+
+	* xterm.c (XTread_socket): Move enter_timestamp outside of the
+	function; static variables inside functions don't always work in
+	Emacs.
+
+	* editfns.c (in_accessible_range): Deleted - insufficently
+	general.
+	(clip_to_bounds): New function, much like in_accessible_range,
+	except that the upper and lower bounds are arguments.
+	(goto_char, save_restriction_restore): Rewritten to use
+	clip_to_bounds instead of in_accessible_range.
+
+1991-02-25  Jim Blandy  (jimb at pogo.ai.mit.edu)
+
+	* keymap.c (initial_define_lisp_key): Turn KEY into a Lisp_Int
+	before passing it to store_in_keymap.
+
+	* buffer.c (reset_buffer_local_variables): Don't try to initialize
+	the buffer's mouse_map and function_key_map fields, since they
+	don't exist anymore.
+
+	* macro.c (kbd_macro_buffer, kbd_macro_ptr, kbd_macro_end): These
+	are now all pointers to Lisp_Objects instead of chars.
+	(Fend_kbd_macro): Use make_sequence.
+	(store_kbd_macro_char): Argument c is now a Lisp_Object.  Change
+	call to xrealloc to ask for Lisp_Objects instead of chars.  Set
+	kbd_macro_end to the same place in the new buffer as it was in the
+	old one, not to the end of the buffer.
+	(Fexecute_kbd_macro): Allow MACRO to be a string or a vector.
+	(syms_of_macros): Allocate Lisp_Objects instead of chars for
+	kbd_macro_buffer.
+
+	* alloc.c (make_sequence): New function, useful to keyboard.c and
+	macro.c.
+	* keyboard.c (Fread_key_sequence): Use make_sequence.
+	(Fthis_command_keys): Use make_sequence.
+
+1991-02-24  Jim Blandy  (jimb at churchy.ai.mit.edu)
+
+	* keymap.c (Fwhere_is): If the command can't be found, the message
+	is now "foobie is not on any key.", instead of "... any keys.".
+
+	* keyboard.c (input_poll_signal): Pass 0 to read_avail_input,
+	instead of `&junk'.  Removed variable `junk'.
+	(command_loop_1): Updated to handle the unified function key/mouse
+	event/keystroke arrangement.
+	(Finput_pending_p): Removed vestiges of code to handle
+	unread_input_char value of -1, since this doesn't happen anymore.
+	(read_char): Adapted to handle lispy events.
+	(read_char_menu_prompt): Allocate `menu' buffer using alloca,
+	instead of a variable-sized array, which is gcc-specific.
+	(Frecent_keys): Return the most recent "keystrokes" as a vector,
+	to accomodate lispy events.
+	(Fset_input_mode): Accomodate non-characters as quit keys.  If
+	this is a bad thing, init_sys_modes will tell us.
+	(init_keyboard): this_command_keys is now an array of
+	Lisp_Objects; adjust the amount of storage we request to hold it.
+	Remember that quit_char can be any keystroke.
+	(syms_of_keyboard): last_command_char, last_input_char, help_char,
+	menu_prompt_more_char and meta_prefix_char are now DEFVAR_LISPs
+	instead of DEFVAR_INTs.
+	
+1991-02-24  Richard Stallman  (rms at mole.ai.mit.edu)
+
+	* process.c (wait_reading_process_input): Use NETCONN_P.
+
+1991-02-23  Jim Blandy  (jimb at pogo.ai.mit.edu)
+
+	* keyboard.c: (recent_keys, this_command_keys,
+	menu_prompt_more_char, help_char, last_command_char, quit_char,
+	last_input_char): Changed to Lisp_Objects, so we can use function
+	keys for them.
+	(Vglobal_function_map): Variable deleted.
+	(echo_char): Echo function keys too.  The argument C is now a
+	Lisp_Object instead of a char.
+	(Fread_key_sequence): Removed sludge to handle window events
+	specially, and added sludge to handle sequences with
+	non-characters in them.
+	(classify_object): Elided, since this should go away soon.
+	(read_key_sequence): Adapted to look up symbols in keymaps,
+	just like characters.
+
+1991-02-23  Richard Stallman  (rms at mole.ai.mit.edu)
+
+	* process.c (send_process): Handle EAGAIN like EWOULDBLOCK.
+
+1991-02-22  Jim Blandy  (jimb at pogo.ai.mit.edu)
+
+	* doc.c (substitute_command_keys): Call describe_map_tree with
+	only three arguments, since the CHARTAB arg has been disposed of.
+
+	* keymap.c (Fcurrent_global_map, Fuse_local_mouse_map): Functions
+	deleted, since the mouse maps are no longer separate from the key
+	maps.
+	(append_key): New function, which handles tacking a single
+	keystroke on the end of a key sequence, promoting strings to
+	vectors when needed.
+	(Faccessible_keymaps): Adjusted to return vectors for key
+	sequences, when necessary.
+	(Fkey_description): Removed stuff to handle mouse buttons and
+	other things specially, since this work will go into
+	Fsingle_key_description.
+	(Fsingle_key_description): SIMPLIFIED to handle everything
+	correctly!  Jeepers!
+	(Fwhere_is_internal): Scan the assoc-list at the end of dense
+	keymaps, and construct strings or vectors.
+	(where_is_string, describe_buffer_bindings): Simplified by
+	deleting code to handle mouse button bindings specially.
+	(describe_map_tree): Removed CHARTAB argument; this was
+	a kludge to print out mouse events nicely, and is no longer
+	necessary.  Nobody was using it anyway.
+	(describe_map): Removed ugly hack to handle mouse buttons
+	specially, added code to describe alists on dense keymaps, and
+	removed CHARTAB argument.
+	(describe_alist): Made to handle bindings of symbols as well as
+	characters.  Removed CHARTAB argument.
+	(describe_vector): Removed CHARTAB argument, allocated KLUDGE
+	outside of loop and GCPRO'd it.
+	(syms_of_keymap): Remove last vestiges of Vglobal_mouse_map,
+	Vmouse_button_names, Suse_local_mouse_map,
+	Scurrent_local_mouse_map.
+
+	* buffer.h (struct buffer): Removed mouse_map and function_key_map
+	members, since they are now handled by the keymap element.
+
+	* keyboard.c (syms_of_keyboard): Change initialization of
+	meta_prefix_char, since it's now a Lisp_Object.
+
+	* keymap.c (Fkeymapp): Rewrote this to use get_keymap_1; now it's
+	a one-liner instead of a 13-liner.
+	(DENSE_TABLE_SIZE): Created new constant for the # of lookup-style
+	entries in a dense keymap, and the index of the map's assoc list.
+	Used it where appropriate.
+	(Fcopy_keymap): Notice that 129'th element in dense keymaps.
+	(Fdefine_key, Flookup_key): Reworked to deal with vectors of
+	symbols and characters as well as strings for key sequences.
+	(meta_prefix_char): Changed from an int to a Lisp_Object.
+
+1991-02-21  Richard Stallman  (rms at mole.ai.mit.edu)
+
+	* fileio.c (report_file_error): Don't downcase "I/O".
+
+1991-02-20  Jim Blandy  (jimb at geech.ai.mit.edu)
+
+	* keymap.c (access_keymap): Allow IDX to be any sort of bindable
+	event, and deal with the extended keymaps.  IDX is now a
+	Lisp_Object instead of an int, obviously.
+	(store_in_keymap): Allow IDX to be any sort of bindable event, and
+	deal with the extended keymaps.  IDX is now a Lisp_Object.
+
+	* xterm.c (construct_mouse_click): Add code to set the up_modifier
+	bit for ButtonRelease events.
+
+	* keyboard.c (kbd_buffer_store_event): Use XFASTINT and XSETINT to
+	access event->code, since it's a Lisp_Object.
+	(kbd_buffer_read_char): Golly, perhaps we should increment
+	kbd_fetch_ptr to remove the event we just read from the queue.
+	(modify_event_symbol): Stupid fixes: correctly look up unmodified
+	symbols when cache entry has a modified symbol vector.  And, when
+	first adding the modified symbol vector, copy the old slot value
+	into it correctly.
+
+1991-02-19  Jim Blandy  (jimb at pogo.ai.mit.edu)
+
+	* keyboard.c (command_loop_1): #if 0 the block of code which
+	handles mouse events and other lispy events specially, since I
+	hope it will go away soon.
+
+	* dispnew.c (Fsleep_for_millisecs): Pass all four arguments to
+	wait_reading_process_input, instead of just the first two.
+
+	* process.c (wait_reading_process_input): Remove support for
+	only waiting for mouse input, since that has been superceded.
+	This removes X dependencies from process.c, and eliminates some
+	references to code that should only exist when using X10.
+
+	* keyboard.c (mouse_moved_symbol, redraw_screen_symbol,
+	mapped_screen_symbol, unmapped_screen_symbol,
+	exited_window_symbol, exited_scrollbar_symbol): Renamed to
+	Qmouse_moved, Qredraw_screen, Qmapped_screen, Qunmapped_screen,
+	Qexited_window, Qexited_scrollbar, just as done in xterm.c.
+	(classify_object): Removed code to look up a function key in the
+	global and local function key keymaps, since this will be done
+	more generally.
+	(Fexecute_mouse_event): Elided this function with a #if 0;  I
+	think it will go away once the more general keymap stuff is
+	implemented, but I'm not sure.
+	(syms_of_keyboard): Removed defsubr for Sexecute_mouse_event.
+	(where_is_string, describe_buffer_bindings, syms_of_keymap):
+	Elided code to handle mouse button bindings specially; I hope this
+	will go away.
+
+	* lread.c (syms_of_lread): Change defsubr for eval-buffer to
+	defsubr for eval-current-buffer.
+
+	* keymap.c (syms_of_keymap): defvar for Vglobal_function_map
+	removed, since that variable has disappeared.
+
+	* xterm.c (x_func_key_to_sym): Removed entirely, since we no
+	longer convert X keycodes to symbols in this section of code.
+	(x_convert_modifiers): New function to turn the X modifier bits
+	into struct input_event modifier bits.
+	(encode_mouse_button): removed, since this work isn't done here
+	anymore.
+	(Vx_send_mouse_movement_events): Add an extern declaration for
+	this.
+
+	* termhooks.h: Only define struct input_event if the module
+	has previously #included lisp.h; this avoids forcing simple modules
+	like cm.c to #include lisp.h.
+
+	* term.c: #include "lisp.h" before #including "termhooks.h", since
+	the latter uses Lisp_Objects now.
+
+	* xfns.c (syms_of_xfns): Delete the defsubr for Sx_window_id,
+	since Fx_window_id is gone.
+
+	* xterm.c (construct_mouse_event): Construct a struct input_event
+	instead of a lispy event.
+
+	* screen.c (coordinates_in_window):  Added explanatory comment. 
+	(window_from_coordinates): Change PART, whose returned values are
+	dependent on X-windows, to be called MODELINE_P, with appropriate
+	new return values.
+	* xterm.c (notice_mouse_movement): Handle the X-windows dependent
+	stuff that used to be in window_from_coordinates here instead.
+	(XTread_socket): Modified to produce struct input_events
+	instead of lispy events.
+
+1991-02-18  Jim Blandy  (jimb at pogo.ai.mit.edu)
+
+        * termhooks.h: Added up_modifier to the enum for modifier bits;
+	this bit will be applied to mouse events.
+	(struct input_event): Changed specification of non_ascii_keystroke
+	events to send the function key number instead of a symbol.
+	* keyboard.c (modify_event_symbol): Re-arranged to work well
+	with function key/mouse button numbers instead of symbols.
+	And if (MODIFIERS & up_modifer), prepend "U-" to the name of the
+	symbol being constructed.
+	(make_lispy_event): Use the new modify_event_symbol.
+
+	* xterm.c (notice_mouse_movement): Adjusted this function to
+	work with a struct input_event instead of producing an
+	s-expression.
+
+	* xterm.c, xfns.c: Made all references to x_mouse_queue,
+	x_expose_queue, and the functions which manipulate them
+	conditional on having X10, since only X10 code ever places
+	anything in these queues.
+
+1991-02-15  Jim Blandy  (jimb at pogo.ai.mit.edu)
+
+	* termhooks.h: Define struct input_event, to represent input
+	events while they sit in the keyboard input buffer.  Using lisp
+	objects to represent input events is a bad idea because the
+	routines which enqueue them can be called from signal handlers,
+	and therefore should not cons.
+
+	* keyboard.c: (kbd_buffer, kbd_fetch_ptr, kbd_store_ptr): Change
+	these to be of type `struct input_event *'.
+	(kbd_buffer_store_event): Manipulate struct input_events instead
+	of lisp objects.
+	(make_lispy_event): New function, to construct a lisp-style event
+	corresponding to a particular struct input_event.
+	(modify_event_symbol): New function, to add modifier prefixes to a
+	symbol, and look the new symbols up quickly if they've already
+	been created.
+	(kbd_buffer_read_char): Call make_lispy_event to turn the thing
+	in the keyboard buffer into the form that read_char is expecting.
+	(Qwith_modifier_keys): Define this new symbol variable.
+	(syms_of_keyboard): Initialize and protect Qwith_modifier_keys.
+
+	* xterm.c (init_input_symbols): Rearranged the code that produces
+	the func_key_syms array.
+	(x_func_key_to_sym): Simplified, since more will be handled in
+	make_lispy_event.
+	(XTread_socket): When handling KeyPress events, don't pass the
+	state of the modifier keys to x_func_key_to_sym, since it doesn't
+	care any more.
+
+	* sysdep.c (kbd_input_ast, end_kbd_input, read_input_waiting):
+	Rename kbd_buffer_store_char to kbd_buffer_store_event.
+
+	* keyboard.c (stuff_buffered_input): Since the keyboard buffer
+	holds lisp objects, only stuff entries that are Lisp_Ints, and
+	XINT them before passing them to stuff_char.
+	(kbd_buffer_store_char): Make this not a static function, since
+	sysdep.c calls it.  And rename it kbd_buffer_store_event.
+
+	* keyboard.c (kbd_buffer, kbd_fetch_ptr, kbd_store_ptr): Made these
+	variables static, to document the fact that they're only used
+	within keyboard.c.
+
+1991-02-13  Jim Blandy  (jimb at pogo.ai.mit.edu)
+
+	* xterm.c (init_input_symbols): remove the `xk-' prefix from all
+	the function key symbols, since they're going to be used for
+	function keys from all sorts of terminals, not just when running
+	under X.
+
+	* lread.c (read_escape): Removed support for mouse button escapes
+	(\S-, \U-, \C- applied to digits), because they're being replaced
+	by something more rational.
+
+1991-02-09  Richard Stallman  (rms at mole.ai.mit.edu)
+
+	* buffer.c: Doc fix.
+
+	* sysdep.c (dup2): Rewrite of non-F_DUPFD case.
+
+1991-02-08  Richard Stallman  (rms at mole.ai.mit.edu)
+
+	* m-intel386.h (LOAD_AVE_CVT): Add extra parens.
+	* s-usg5-4.h (LIBX11_SYSTEM): #undef it.
+
+1991-02-07  Richard Stallman  (rms at mole.ai.mit.edu)
+
+	* s-esix.h: New version from kayvan.
+	Adds HAVE_X11 conditional, NEED_PTEM_H, USG_SYS_TIME, USE_UTIME,
+	LIBS_DEBUG; removes #undef sigsetmask, LIBS_SYSTEM, ESIX, 
+	MISSING_UTIMES.
+
+1991-02-06  Richard Stallman  (rms at mole.ai.mit.edu)
+
+	* process.c (Faccept_process_output): Second arg gives timeout.
+
+1991-02-06  Jim Blandy  (jimb at geech.ai.mit.edu)
+
+	* lread.c (read_escape): Added support for \S- and \U- escapes (for
+	binding mouse buttons), and noted that \C- must work on digits.
+
+	* xterm.c (init_input_symbols): Was mistakenly renamed
+	init_inputs; named back.
+
+	* xterm.c (construct_mouse_click, encode_mouse_button): Rewritten
+	to build new-style mouse events.
+
+	* dispnew.c (update_line): Write a zero into obody[olen] to make
+	sure the lines in current_screen->glyphs remain terminated.
+	* xdisp.c (display_string, display_text_line): Don't write off
+	the end of the line and destroy the zero terminator when expanding
+	a tab.
+
+	* fns.c (Fy_or_n_p): Accept C-] (usually abort-recursive-edit) as
+	well as C-g to quit.
+
+1991-02-05  Jim Blandy  (jimb at geech.ai.mit.edu)
+
+	* sysdep.c, s-aix3-1.h, s-hpux.h, s-iris3-5.h, s-iris3-6.h,
+	s-irix3-3.h, s-rtu.h, s-sunos4-1.h, s-unipl5-0.h, s-unipl5-2.h,
+	s-usg5-0.h, s-usg5-2-2.h, s-usg5-2.h, s-usg5-3.h, s-xenix.h:
+	Globally replaced INTERRUPTABLE with INTERRUPTIBLE.
+
+	* xterm.c (construct_mouse_event): Renamed to
+	construct_mouse_click, since there are kinds of mouse events
+	besides clicks (movement, for example).
+	(XTread_socket): rename calls here.
+
+	* xterm.c (mapped_screen_symbol, unmapped_screen_symbol,
+	exited_scrollbar_symbol, exited_window_symbol,
+	redraw_screen_symbol, mouse_moved_symbol): Renamed to
+	Qmapped_screen, Qunmapped_screen, Qexited_scrollbar,
+	Qexited_window, Qredraw_screen, Qmouse_moved, to agree with naming
+	conventions elsewhere in Emacs.
+
+	* xfns.c (text_part_sym, modeline_part_sym,
+	vertical_scrollbar_sym, vertical_slider_sym, vertical_thumbup_sym,
+	vertical_thumbdown_sym, horizontal_scrollbar_sym,
+	horizontal_slider_sym, horizontal_thumbleft_sym,
+	horizontal_thumbright_sym): Renamed to Qtext_part, Qmodeline_part,
+	Qvscrollbar_part, Qvslider_part, Qvthumbup_part, Qvthumbdown_part,
+	Qhscrollbar_part, Qhslider_part, Qhthumbleft_part,
+	Qhthumbright_part, to agree with the naming conventions elsewhere
+	in Emacs.
+
+	* xterm.c (XTread_socket): While handling EnterNotify events,
+	clear Vmouse_event here.
+	(notice_mouse_movement): Don't clear it here.
+
+1991-02-04  Richard Stallman  (rms at mole.ai.mit.edu)
+
+	* s-sunos4-0.h: Renamed from s-sunos4.h.
+	(read, write, open, close): Macro defs moved to s-sunos4-1.h.
+	(INTERRUPTABLE_*): Likewise.
+	* s-sunos4-1.h: New file.
+
+1991-02-04  Jim Blandy  (jimb at churchy.ai.mit.edu)
+
+	* keymap.c (Vglobal_mouse_map, Vglobal_function_map): Variables
+	removed in preparation for conversion to unified keymap format.
+	(Fmake_keymap): Make vector keymaps with 129 entries; the last
+	will be an assoc-list for looking up symbols.  Update docstring to
+	describe 129'th element.
+	(Fmake_sparse_keymap): Update docstring to say that you can bind
+	symbols in these maps too.
+	(Fkeymapp): Recognize 129-element vectors as keymaps, not
+	128-element vectors.
+	(get_keymap_1): wrong_type_argument can no longer return a new
+	value supplied by the debugger; remove loop to support this.
+
+	* xterm.c (XTread_socket): When handling EnterNotify events,
+	enqueue fake mouse events iff Vx_send_mouse_movement_events !=
+	Qnil.
+
+	* xfns.c (Fx_window_id): Function removed; Fscreen_parameters
+	already provides this information.
+
+	* xterm.c (x_term_init): Cleaned up the code to get the host name,
+	and removed fixed limit on host name length.
+
+	* window.c (Fscroll_other_window): Don't explicitly save
+	current_buffer and point; the save_excursion will take care of
+	that anyway.
+
+	* dispnew.c (safe_bcopy): Rewritten to handle overlapping regions
+	with multiple calls to bcopy instead of a stupid copy loop.
+
+	* xterm.c, xfns.c (Vscreen_part, Vx_send_movement_events): These
+	variables renamed to Vmouse_screen_part,
+	Vx_send_mouse_movement_events.
+
+	* lread.c (Feval_buffer): function deleted.
+	(Feval_current_buffer): Removed "#if 0 ... #endif" around this
+	function.
+
+1991-02-03  Richard Stallman  (rms at mole.ai.mit.edu)
+
+	* Makefile, ymakefile (SHELL): Force use of sh.
+
+	* s-usg5-4.h (USG5_4): Define it.
+	(LOAD_AVE_*): Don't define them.
+	* m-intel386.h (LOAD_AVE_*): Define, if USG5_4.
+
+	* buffer.c (Fbuffer_local_variables): Omit slots with no names.
+
+1991-02-03  Jim Blandy  (jimb at geech.ai.mit.edu)
+
+	* xterm.c (x_term_init, init_input_symbols): Moved these to the
+	bottom of the file, 1) to be consistent with the other files, and
+	2) so it can initialize some variables I want.
+
+1991-02-02  Jim Blandy  (jimb at churchy.ai.mit.edu)
+
+	* xterm.h: Added external declaration for x_focus_screen.
+
+	* search.h: File deleted.
+	* buffer.h: declare searchbuf here instead.
+
+	* screen.c (Ffocus_screen, Funfocus_screen): Moved these functions
+	to xfns.c, since they're x-specific.
+	(syms_of_screen): Removed defsubr calls for above.
+	* xfns.c (Ffocus_screen, Funfocus_screen): Here they are.
+	(syms_of_xfns): The defsubrs are here now.
+
+	* buffer.h (PT): Make this expand to an expression which is not an
+	l-value, to prevent people from assigning to it.  If everyplace
+	uses SET_PT, it will be easier to merge in the interval code.
+	(point): Similar changes here.
+	(SET_PT): This can no longer be written in terms of PT, so write
+	out current_buffer->text.pt.
+
+	* xterm.c (x_new_font): Rewritten to remove arbitrary limit on
+	size of x_font_table.
+	(x_font_table_size): Created new variable.
+	(n_available_fonts, font_names, font_info, MAX_FONTS): Deleted
+	these variables/macros.
+
+	* dispnew.c (scroll_screen_lines): Instead of disabling the lines
+	vacated by the scroll (i.e. zeroing enable), mark them as enabled
+	but empty.
+
+	* callint.c (Fcall_interactively): Move UNGCPRO down, so that
+	stuff is protected while we build the command history entry and do
+	the function call.
+
+	* xterm.c (XTupdate_end): Turn cursor on, even if we don't
+	currently have the focus.
+
+	* minibuf.c (temp_echo_area_glyphs): Clear echo_area_glyphs and
+	previous_echo_glyphs, so the message we're displaying will
+	supercede any existing message.
+
+	* keyboard.c: Removed external declaration of echo_area_glyphs,
+	since it's declared in window.h.
+
+1991-01-31  Jim Blandy  (jimb at pogo.ai.mit.edu)
+
+	* xterm.c (XRINGBELL): Pass 0 as the second argument to XBell;
+	respect the user's preferences.
+
+1991-01-30  Jim Blandy  (jimb at pogo.ai.mit.edu)
+
+	* xterm.c (x_draw_single_glyph): New function, created to simplify
+	cursor drawing/undrawing.
+	(x_display_box_cursor): Rewritten to properly handle the box
+	cursor in its filled and hollow forms.
+	* xterm.h (enum text_cursor_kinds): Added enum for the different
+	kinds of cursors which might be displayed in a window.
+	(struct x_display): added member `text_cursor_kind' which says
+	which kind of cursor is currently being displayed in the window, so
+	we can arrange to redraw it effectively.
+
+	* keyboard.c (command_loop_1): When handling the forward_char
+	command, don't let point move to the location after the end of the
+	buffer.
+
+	* keyboard.c (poll_suppress_count): Define this even if
+	POLL_FOR_INPUT is not defined, because this makes lots of #ifdef
+	clauses unnecessary, and doesn't hurt, because
+	{start,stop}_polling become nops.
+
+	* config.h, config.h-dist: Make these #include "system.h" and
+	"machine.h", and let the config script link these appropriately,
+	instead of using the machine-specific names and expecting the user
+	to edit this file.
+
+1991-01-29  Jim Blandy  (jimb at churchy.ai.mit.edu)
+
+	* window.c (Fdelete_window): sib is a Lisp_Object; treat it as
+	such.
+
+	* xterm.c (screen_unhighlight): When the focus leaves a screen,
+	draw the cursor as a box instead of making it disappear entirely.
+
+1991-01-29  Richard Stallman  (rms at mole.ai.mit.edu)
+
+	* unexec.c (make_hdr) [TPIX]: Set f_hdr.f_nscns and f_thdr.f_scnptr.
+
+	* sysdep.c [BROKEN_TIOCGWINSZ]: Undef TIOCGWINSZ.
+
+	* process.c (wait_reading_process_input): Don't ignore
+	a zero-length read on a network connection.  Do close it.
+
+	* sysdep.c (hft_init, hft_reset): Pass &junk as arg to HFQERROR.
+	Do nothing if not HFT.
+
+1991-01-29  Jim Blandy  (jimb at albert.ai.mit.edu)
+
+	* xfns.h: Created, to declare things defined in xfns.c.
+	Declare Vx_send_movement_events.
+	* xfns.c: #include "xfns.h".
+	(Vx_send_movement_events): Define this variable.
+	(syms_of_xfns): DEFVAR_LISP it.
+	* xterm.c: #include "xfns.h".
+	(XTread_socket): Place a mouse-moved event in the buffer iff
+	Vx_send_movement_events says to.
+
+1991-01-28  Jim Blandy  (jimb at geech.ai.mit.edu)
+
+	* ymakefile: noted that callint.o depends on mocklisp.h,
+	and dired.o on search.h.
+
+	* environ.h: Deleted - its creation in the first place was misguided.
+	callproc.h: Removed #include "environ.h", and added declarations
+	for environ.h
+
+	* buffer.c (syms_of_buffer): Add more detailed documentation to
+	buffer-undo-list.
+
+	* lisp.h (poll_suppress_count): Add external declaration for this here.
+
+1991-01-28  Richard Stallman  (rms at mole.ai.mit.edu)
+
+	* m-sun3-68881.h, m-sun3-fpa.h, m-sun3-soft.h: New files.
+
+1991-01-27  Jim Blandy  (jimb at geech.ai.mit.edu)
+
+	* lisp.h (struct handler): add poll_suppress_count member, so
+	we can restore poll_suppress_count when we handle an error.

+
+	* dispnew.c (buffer_posn_from_coords): compute_motion starting

+	And rotate by amount, not -amount, in the up-scrolling section.
+
+	* xterm.h (MAX_FONTS, x_font_table, n_fonts): Removed external

+
+	* xterm.c (x_new_font): If you can't find the requested font,

+
+	* xdisp.c (redisplay, display_mode_line): To test

+	to Qnil; otherwise, it inhibits decent redisplay (is that another
+	bug?)
+
+	* dispnew.c (init_display): Make sure that the standard input is a

+	format to 32 and send only 1 element.  Pass the address of size,

+
+	* xfns.c (x_window): Don't use backing store or saveunders; they

+	(x_make_gc): Initialize gc_values.line_width to zero before
+	creating the normal video GC, since it uses it.  And set the

+	(install_vertical_scrollbar): Add 2 to thumbdown y position, and
+	don't add ibw.
+
+	* insdel.c (insert, del_range): Use SET_PT rather than assigning
+	point directly.
+	* window.c (Fselect_window): Here too.
+
+	* xdisp.c (redisplay_all_windows): removed static declaration for
+	this nonexistent function.
+
+1991-01-04  Jim Blandy  (jimb at pogo.ai.mit.edu)
+
+	* window.c (window_loop): neatened up.  MINI being non-zero now
+	makes it recognize active minibuffer windows.  Iterates properly
+	over multiple screens when asked nicely.
+	(Fget_lru_window, Fget_largest_window): SCREENS arguments are now
+	declared as a Lisp_Object, and documented.
+	(Fget_buffer_window): SCREENS argument is now documented.

+
+	* search.c (search_buffer): Return starting position if count == 0.
+
+1991-01-02  Jim Blandy  (jimb at pogo.ai.mit.edu)

+	lines just inserted--old version lost a line.

+	(Ffocus_screen, Funfocus_screen): use Joe's new definitions, and
+	only define these functions ifdef HAVE_X_WINDOWS.
+	(window_from_coordinates): use next_screen_window instead of
+	Fnext_window, so that global minibuffers work.
+
+	* lread.c (syms_of_read): Don't forget to defsubr
+	read-char-exclusive.
+
+	* lisp.h (Fscreenp, Fselect_screen, Ffocus_screen,

+	extern declarations for all these.
+
+	* lisp.h (Qscreenp): added an extern declaration for this.
+
+	* lisp.h (DBL_DIG): Added constant for the maximum number of
+	decimal digits a float could print to.  Used in print.c.

+	can be bound - this includes keys, symbols (for function keys and
+	window system events), and conses (for mouse events).
+	* lisp.h (Qkeyp): Added external declaration for this.
+
+	* keyboard.c (Frecursive_edit): Don't specbind the standard IO here.
+	(recursive_edit_1): Do it here, and don't forgot to unbind_to.

+	(classify_object): Place the object in read_key_sequence_cmd.
+
+	(Fread_key_sequence): recognize that when read_key_sequence
+	returns -1 or -2, it's a mouse event or window system event.
+
+1991-01-01  Jim Blandy  (jimb at pogo.ai.mit.edu)
+
+	* fileio.c (Fwrite_region): We should dereference GPT_ADDR[-1]
+	before comparing it to '\n' for VMS cruft.
+	(Fdo_auto_save): Don't call run-hooks before it's defined.  This
+	only happens before emacs is dumped, when loading inc-vers.el.

+
+	(Feval): We use argvals[0..5], so declare it to have six elements
+	instead of just five.
+
+1990-12-30  Richard Stallman  (rms at mole.ai.mit.edu)
+
+	* eval.c (Fsignal): Don't ever return.
+	Call error instead if user tries to use debugger to return.
+
+	* eval.c (unbind_to): New second arg is value to return.  gcpro it.
+	All callers changed to pass the arg; if a caller uses unbind_to
+	just before returning, it passes as this arg the value it wants
+	to return, then it returns whatever comes back.
+
+1990-12-28  Jim Blandy  (jimb at geech.ai.mit.edu)
+
+	* print.c (print): put obj in a non-register variable so

+
+	* editfns.c (Fformat): declare nstrings, and declare nstrings and
+	strings in a local block.
+	(Fformat): XFLOAT(args[n]) isn't a float; ->data is.

+
+	* callproc.c (Fcall_process): change synch_process_pid to

+
+	* dispnew.c (init_display): Check if we're using a window system
+	before trying to initialize the terminal.  If someone has

+
+1990-11-13  Richard Stallman  (rms at mole.ai.mit.edu)
+
+	* fileio.c (err_str): New macro.

+	buffer viewed by Vmouse_window instead.
+
+	* alloc.c (xmalloc, xrealloc): removed calls to
+	{un,}hold_window_change.  The new SIGWINCH-handling code and
