+2000-12-30  Michael Livshin  <mlivshin@bigfoot.com>
+
+	* guardians.c (guardian_print): for sharing guardians, print that
+	they are sharing.
+	(scm_guard, scm_get_one_zombie): place the critical section
+	barriers more correctly.
+
+	* weaks.c (scm_scan_weak_vectors): move the calculation of the
+	`weak_keys' and `weak_values' flags out of the inner loop.
+
+2000-12-29  Michael Livshin  <mlivshin@bigfoot.com>
+
+	* guardians.c: (greedily_guarded_prop): deleted.
+	(greedily_guarded_whash): new variable.  a doubly-weak hash table
+	used to keep the "greedily guarded" object property.  the previous
+	implementation (via primitive object properties) was incorrect due
+	to its only-the-key-is-weak semantics.
+	(scm_guard, get_one_zombie, scm_init_guardians): use/init
+	`greedily_guarded_whash'.
+
+2000-12-28  Dirk Herrmann  <D.Herrmann@tu-bs.de>
+
+	* eval.c (check_map_args), gh_data.c (gh_set_substr,
+	gh_scm2newstr, gh_get_substr, gh_symbol2newstr), print.c
+	(scm_iprin1):  Use scm_remember_upto_here_1 instead of
+	scm_remember.
+
+	* gc.[ch] (scm_remember_upto_here_1, scm_remember_upto_here_2,
+	scm_remember_upto_here):  New functions.
+
+	(scm_remember):  Deprecated.
+
+2000-12-28  Dirk Herrmann  <D.Herrmann@tu-bs.de>
+
+	* continuations.c (scm_make_continuation):  Make variable cont
+	volatile to let the compiler know that it won't be clobbered by
+	longjmp.  (It wouldn't be anyway, but for some reason the compiler
+	is not able to see that.)
+
+2000-12-28  Dirk Herrmann  <D.Herrmann@tu-bs.de>
+
+	This patch re-introduces the unused member "properties" of
+	struct scm_subr_entry as requested by Mikael Djurfeldt.
+
+	* procs.h (scm_subr_entry):  Re-introduced member "properties".
+
+	(SCM_SUBR_PROPS):  Un-deprecated.
+
+	* procs.c (scm_make_subr_opt, scm_mark_subr_table):  Struct
+	scm_subr_entry has a member "properties" again.
+
+2000-12-28  Michael Livshin  <mlivshin@bigfoot.com>
+
+	* guardians.c (mark_dependencies_in_tconc): new function.
+	(mark_dependencies): bug fix.  mark the dependencies of the known
+	zombies, too.  duh.
+
+2000-12-24  Michael Livshin  <mlivshin@bigfoot.com>
+
+	* gc.c: (scm_gc_mark_dependencies): use SCM_EQ_P for SCMs, not
+	'=='.  also, return after calling `scm_gc_mark'.
+
+2000-12-24  Michael Livshin  <mlivshin@bigfoot.com>
+
+	* gc.c: (scm_gc_mark_dependencies): new function.  like
+	`scm_gc_mark', but doesn't mark the argument itself.  defined
+	using an arrangement similar to that in eval.c: `scm_gc_mark' and
+	`scm_gc_mark_dependencies' are derived from the same "template"
+	by ugly preprocessor magic.
+
+	* gc.h: added prototype for `scm_gc_mark_dependencies'.
+
+	* init.c (scm_init_guile_1): call the renamed
+	`scm_init_guardians'.
+
+	* guardians.h: changed prototypes for `scm_make_guardian' and
+	`scm_init_guardians'.
+
+	* guardians.c (guardian_t): added new fields `greedy_p' and
+	`listed_p'.
+	(GUARDIAN_P): predicate that says whether its argument is a
+	guardian.
+	(GUARDIAN_GREEDY_P, GUARDIAN_LISTED_P): new predicates.
+	(greedy_guardians, sharing_guardians): new variables.  hold the
+	greedy and sharing live guardian lists, respectively.
+	(first_live_guardian, current_link_field): removed.
+	(greedily_guarded_prop): new variable.  holds the "is greedily
+	guarded" object property.
+	(self_centered_zombies): new variable.  stores guarded objects
+	that are parts of cycles.
+	(add_to_live_list): new function, introduced to decouple marking a
+	guardian and adding it to the live list.
+	(guardian_mark): call `add_to_live_list'.
+	(guardian_print): print whether the guardian is greedy or not.
+	also change "live" and "zombie" to "reachable" and "unreachable"
+	respectively, to be less confusing.
+	(scm_guard): if the guardian is greedy, test whether the object is
+	already greedily marked.  throw an error if so.
+	(scm_get_one_zombie): if the guardian is greedy, remove the
+	"greedily guarded" property from the object.
+	(scm_make_guardian): add a new optional boolean argument which
+	says whether the guardian is greedy or sharing.
+	(guardian_gc_init): init the new live lists.
+	(mark_dependencies): new function.
+	(mark_and_zombify): new function.
+	(guardian_zombify): reworked to support the new guardian
+	semantics.  move some logic to `mark_dependencies' and
+	`mark_and_zombify'.
+	(whine_about_self_centered_zombies): new function.  installed in
+	the `after-gc-hook' to complain about guarded objects which are
+	parts of cycles.
+	(scm_init_guardians): init the new stuff.  renamed from
+	`scm_init_guardian'.
+
+2000-12-23  Dirk Herrmann  <D.Herrmann@tu-bs.de>
+
+	* procs.h (scm_subr_entry):  Removed unused struct member
+	"properties".
+
+	(SCM_SUBR_PROPS):  Deprecated.
+
+	* procs.c (scm_make_subr_opt, scm_mark_subr_table):  Struct
+	scm_subr_entry does not have a member "properties" any more.
+
+2000-12-22  Dirk Herrmann  <D.Herrmann@tu-bs.de>
+
+	* procs.h (scm_subr_entry):  Removed unused struct member
+	"documentation".
+
+	(SCM_SUBR_DOC):  Deprecated.
+
+	* procs.c (scm_make_subr_opt):  Eliminate use of scm_intern0 in
+	favor of scm_str2symbol.  Similarly, prefer scm_sysintern over
+	scm_sysintern0.
+
+	(scm_make_subr_opt, scm_mark_subr_table):  Struct scm_subr_entry
+	does not have a member "documentation" any more.
+

+	current environment will take effect when re-entering the dynamic
+	scope.
+
+2000-12-21  Dirk Herrmann  <D.Herrmann@tu-bs.de>
+
+	* goops.h (SCM_PUREGENERICP):  Include the SCM_STRUCTP test.
+
+	* goops.c (scm_sys_invalidate_method_cache_x, scm_m_atdispatch,
+	scm_pure_generic_p):  The SCM_STRUCTP test is implied.
+
+2000-12-20  Gary Houston  <ghouston@arglist.com>
+
+	* continuations.c (continuation_apply): subtract the length of
+	continuation->dynenv, not the dynenv itself.  I broke it last
+	time I changed this file.  thanks to Bernard Urban.
+
+2000-12-16  Dirk Herrmann  <D.Herrmann@tu-bs.de>
+
+	* goops.c (remove_duplicate_slots, maplist,

+
+2000-12-16  Dirk Herrmann  <D.Herrmann@tu-bs.de>
+
+	* environments.[ch] (scm_system_environment):  New variable, will
+	replace scm_symhash soon.  We may decide for a better name and
+	also to split this up into a set of environments later.
+
+	(scm_environments_prehistory):  Initialize scm_system_environment.
+
+	* init.c (scm_init_guile_1):  scm_environments_prehistory requires
+	storage to be initialized.
+
+2000-12-15  Dirk Herrmann  <D.Herrmann@tu-bs.de>
+
+	* eval.c (change_environment, inner_eval, restore_environment):
+	New functions.
+
+	(scm_eval):  Bring the global variable that holds the current

+	most-positive-fixnum and most-negative-fixnum as requested by
+	Mikael Djurfeldt.
+
+2000-12-12  Dirk Herrmann  <D.Herrmann@tu-bs.de>
+
+	The variable scm_symbols is made static within symbols.c and
+	renamed to symbols.  The initialization of the symbols hash table
+	is done in function scm_symbols_prehistory.
+
+	* gc.c (scm_init_storage):  Don't initialize scm_symbols.  Don't
+	define most-positive-fixnum, most-negative-fixnum and
+	bignum-radix.
+
+	* init.c (scm_init_guile_1):  Call scm_symbols_prehistory.
+
+	* root.h (scm_symbols):  Not in scm_sys_protects any more.
+
+	* symbols.c (symbols):  Renamed from scm_symbols and made static.

+
+	* gc.c (scm_init_storage), root.h (scm_weak_symhash, scm_symbols):
+	Removed the former scm_weak_symhash hash table.  Added scm_symbols
+	hash table.
+
+	* stacks.c (get_applybody):  scm_sym2vcell may return #f.
+
+	* symbols.c (scm_mem2symbol):  This function is now responsible
+	for creating symbol objects and storing them in the global
+	scm_symbols hash table.
+
+	(scm_str2symbol):  Rewritten in terms of scm_mem2symbol.
+
+	(scm_sym2vcell):  For system bindings, there is now only one
+	obarray - scm_symhash.  If scm_sym2vcell is called to look up a
+	symbol that can't be found and shall not be created, #f is
+	returned.  Most callers of scm_sym2vcell have expected this
+	behaviour anyway.
+
+	(scm_intern_obarray_soft):  Removed reference to scm_weak_symhash
+	from comment.
+
+	(scm_intern_obarray_soft, scm_sysintern0_no_module_lookup):  These
+	functions are not responsible for symbol creation any more, only
+	for creation of bindings.

+	a symbol object.
+
+	(scm_symbol_interned_p):  scm_weak_symhash is removed.

+	* symbols.[ch] (scm_builtin_weak_bindings):  Removed.  There are
+	no weak bindings any more.
+

+	(scm_compile_shell_switches), snarf.h (SCM_VCELL,
+	SCM_GLOBAL_VCELL, SCM_VCELL_INIT, SCM_GLOBAL_VCELL_INIT):  Create
+	a binding in one go (instead of first creating a vcell and then
+	setting its cdr).
+
+2000-12-12  Dirk Herrmann  <D.Herrmann@tu-bs.de>
+
+	* hash.[ch] (scm_string_hash), symbols.[ch] (scm_string_hash):
+	Moved function scm_string_hash to hash.c.
+
+2000-12-11  Marius Vollmer  <mvo@zagadka.ping.de>
+
+	* gc_os_dep.c (scm_get_stack_base) [MSWIN32]: Added detection of
+	page size on the w32 architecture.  Updated from Boehms gc5.2.

+
+	* gc.[ch] (scm_init_storage):  Read gc configuration environment
+	variables here, not in init.c.
+
+	* init.c (scm_i_getenv_int):  Moved to gc.c.
+
+	(scm_init_guile_1):  Move configuration code to scm_init_storage.
+	Make sure procprops get initialized early.
+
+	* keywords.c (scm_c_make_keyword):  Report amount of memory freed
+	by scm_must_free.  Use scm_str2symbol instead of scm_sysintern0.
+
+	* options.c (scm_init_opts):  Use scm_str2symbol instead of
+	scm_sysintern0.
+
+2000-12-10  Mikael Djurfeldt  <mdj@linnaeus.mit.edu>

+	to George Caswell.
+
+2000-11-09  Gary Houston  <ghouston@arglist.com>
+
+	* ports.c, ports.h (scm_close_all_ports_except): deprecated.

+	which applies a procedure to each port in the port table.
+	ports.h: declare scm_port_for_each.
+
+	* ioext.c (scm_dup2): new proc.  implements "dup2" which is a simple
+	wrapper for the dup2 system call (unlike dup->fdes or
+	primitive-move->fdes).
+	* ioext.h: declare scm_dup2.
+
+	* filesys.c (scm_close_fdes): new proc.  implements "close-fdes"
+	which is a simple wrapper for close system call (unlike scm_close).
+	* filesys.h: declare for scm_close_fdes.

+	(Thanks to Lars J. Aas.)
+
+2000-11-04  Gary Houston  <ghouston@arglist.com>
+
+	* ports.c (scm_port_p): new function, implements "port?" which

+
+	* backtrace.c (display_expression, display_error_body), fports.c
+	(prinfport), print.c (scm_iprin1):  Test for symbols and strings
+	explicitly instead of using SCM_ROSTRINGP.
+
+	* backtrace.c (scm_display_error_message):  Don't pass a symbol to
+	scm_simple_format.  Prefer high-level output functions.
+
+	(display_error_body):  When displaying procedure names, give
+	preference to the name passed as a parameter.  Only if none is

+
+	* fports.c (scm_fdes_to_port, prinfport), gc.c (scm_gc_mark),
+	ports.c (scm_port_filename, scm_set_port_filename_x):  Use
+	SCM_(SET_)?FILENAME.

+	strings in order to treat substrings right.  Reposition call to
+	scm_remember after the last use of object's data.
+
+	(scm_simple_format):  Treat messages that are substrings right.
+
+	* symbols.h (SCM_ROSTRINGP):  Deprecated.

+
+	(scm_intern_obarray_soft):  Speed up search for a matching symbol
+	by comparing the hash values first.
+
+2000-10-30  Dirk Herrmann  <D.Herrmann@tu-bs.de>
+
+	* unif.c (scm_make_uve, scm_dimensions_to_uniform_array):  Don't
+	allow vectors longer than SCM_LENGTH_MAX. This removes the
+	SCM_HUGE_LENGTH trick, i. e. storing a vector length greater than
+	SCM_LENGTH_MAX at the beginning of the vector's memory.  Since not
+	all of guile's code was implemented to be aware of this trick, it
+	is unlikely that it was used anyway.  We can implement such a
+	feature more cleanly by using double cells for uniform vector
+	types.
+
+	(scm_shap2ra):  Replace SCM_IMP and SCM_NIMP tests by more
+	straightforward predicates.
+
+	(scm_dimensions_to_uniform_array):  Require that for dimensions

+	less than the lower bound.

+
+	* dynl.c (scm_coerce_rostring):  Removed.
+

+
+	* error (scm_error_scm):  Don't accept a symbol as message
+	parameter.  Fix substring handling.
+
+	* posix.c (environ_list_to_c):  Use memcpy to copy environment

+
+	* random.c:  Include unif.h.
+
+	* strings.h (SCM_STRING_COERCE_0TERMINATION_X):  Added.  This is

+
+2000-10-25  Mikael Djurfeldt  <mdj@linnaeus.mit.edu>
+
+	This change merges the GOOPS code into Guile.  However, GOOPS
+	is still not initialized until someone asks for the module.
+	We need to optimize GOOPS initialization time before initializing
+	it together with the rest of libguile.  We also need to add the
+	C API + primitive methods.  Then we can start using it to
+	modularize Guile, implement a real exception system etc.
+
+	* goops.c, objects.c, objects.h, eval.c (scm_make_extended_class,
+	scm_make_port_classes, scm_change_object_class,
+	scm_memoize_method): Changed to ordinary functions (was plugin

+
+	* eval.c (scm_lookupcar):  Use SCM_ITAG7 instead of doing bit
+	operations directly.
+
+	* filesys.c (scm_dirname, scm_basename):  Don't create shared
+	substrings as these are going to disappear from guile.
+
+	* gc.c (scm_gc_sweep):  Use SCM_UVECTOR_LENGTH instead of

+
+	* read.c (scm_flush_ws):  Don't compare SCM values directly.
+
+	* root.c (scm_make_root), root.h (scm_root_state):  Removed

+
+	This patch unifies the formerly distinct ssymbol and msymbol types
+	to a common symbol type scm_tc7_symbol.  The representation of the
+	new symbol type uses a double cell with the following layout:
+	<type/length, chars, raw_hash, prop-pair>, where the car of
+	prop-pair holds the symbol's function property and the cdr of
+	prop-pair holds the symbol's other properties.  In the long run,
+	these properties will be removed.  Then, the generic property
+	functions will be uses.
+
+	* eval.c (SCM_CEVAL), objects.c (scm_class_of), print.c
+	(scm_iprin1), tag.c (scm_tag):  Use scm_tc7_symbol instead of

+	* gc.c (scm_gc_mark):  Mark the symbols property pair.
+
+	(scm_gc_sweep):  There are no symbol slots any more.

+	of a symbol, use the raw_hash value stored in the symbol itself.
+
+	* properties.h:  Fix typo.
+
+	* strings.[ch] (scm_makstr, scm_makfromstr):  The slot parameter
+	is not used any more.
+
+	* symbols.[ch] (scm_strhash):  Deprecated, replaced by a macro.
+
+	(scm_intern_obarray_soft):  Made softness parameter unsigned.
+
+	(scm_string_hash):  New function with the same functionality as
+	scm_strhash had before, except that the hash value is not adjusted
+	to a hash table size.  Instead, the 'raw' hash value is returned.
+
+	* symbols.c (duplicate_string):  New static convenience function.
+
+	(scm_sym2vcell, scm_sym2ovcell_soft, scm_intern_obarray_soft):
+	Renamed local variable from scm_hash to hash.
+
+	(scm_intern_obarray_soft):  Don't check for a negative softness
+	any more.  When generating symbol cells, use the new layout and
+	store the raw hash value in the symbol's cell.
+
+	(scm_symbol_to_string):  Removed unnecessary cast.
+
+	(scm_intern_symbol, scm_unintern_symbol):  Use scm_string_hash to

+	(scm_symbol_hash):  Comment fixed.
+
+	* symbols.h:  Comment about the distinction between ssymbols and
+	msymbols removed.
+
+	(SCM_SYMBOLP, SCM_ROSTRINGP):  No need to distinguish between

+	(SCM_PROP_SLOTS, SCM_SET_PROP_SLOTS):  Added.
+
+	(SCM_SYMBOL_FUNC, SCM_SET_SYMBOL_FUNC, SCM_SYMBOL_PROPS,
+	SCM_SET_SYMBOL_PROPS, SCM_SYMBOL_HASH, SCM_SET_SYMBOL_HASH):  Use
+	the new symbol cell layout.
+
+	* tags.h (scm_tc7_ssymbol, scm_tc7_msymbol, scm_tcs_symbols):
+	Deprecated.
+
+2000-09-12  Mikael Djurfeldt  <mdj@linnaeus.mit.edu>
+
+	* symbols.h (scm_gentemp): Declared.
+
+	* symbols.c (scm_gensym): Reimplemented.  Now only takes one

+2000-09-10  Keisuke Nishida  <kxn30@po.cwru.edu>

+	is an eval closure.
+
+2000-09-10  Mikael Djurfeldt  <mdj@linnaeus.mit.edu>
+
+	* Makefile.am (.x.doc): Bugfix: Added $(srcdir) to path in order

+
+	* symbols.c (scm_gensym): Bugfixed my previous bugfix.  (Thanks to
+	Dale P. Smith.)
+
+2000-09-10  Keisuke Nishida  <kxn30@po.cwru.edu>

+
+2000-09-05  Mikael Djurfeldt  <mdj@linnaeus.mit.edu>

+
+2000-09-03  Mikael Djurfeldt  <mdj@linnaeus.mit.edu>
+
+	* validate.h (SCM_VALIDATE_NUMBER_DEF_COPY): New macro.
+
+2000-09-03  Marius Vollmer  <mvo@zagadka.ping.de>
+
+	* Makefile.am (.x.doc): Pretend to create .doc files from .x files
+	and give explicit dependencies for .x files that depend on
+	generated files.  This allows parallel builds.  Thanks to Matthias
+	Koeppe!
+
+2000-08-27  Marius Vollmer  <mvo@zagadka.ping.de>
+
+	* Makefile.am: Added gc_os_dep.c, properties.c, properties.x,

+
+	* root.h (scm_properties_whash): New `sys_protect', used in
+	properties.c.
+
+	* throw.c (scm_ithrow): Perform catch-all handling here when no
+	suitable handler has been found.  That way, we don't have to rely
+	on the user establishing a catch-all, which might be difficult for
+	him if he is using scm_init_guile instead of scm_boot_guile.
+	
+2000-09-03  Neil Jerram  <neil@ossau.uklinux.net>

+
+2000-09-03  Michael Livshin  <mlivshin@bigfoot.com>
+
+	the following changes let Guile get rid of the `allocated' cell

+	type.
+
+	* tags.h (scm_tc16_allocated): removed.

+
+	* objects.c (scm_init_objects), print.c (scm_init_print), struct.c
+	(scm_init_struct): First arg to scm_make_vtable_vtable should be a

+	(scm_make_vtable_vtable): Check that argument is a string.
+
+	* environments.c (scm_init_environments): All internal includes in
+	libguile must use the prefix "libguile/" in path names since inly
+	the top-level source directory is on the include list.  (That, in
+	turn, is because we want to distinguish between system header
+	files and hedares files internal to libguile.)
+
+	* strings.c (scm_make_shared_substring, scm_read_only_string_p):
+	Deprecated.
+	(scm_string_length, scm_string_ref, scm_substring,

+2000-08-24  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
+
+	* Makefile.am (BUILT_SOURCES): Experimentally added scmconfig.h
+	also here.  (This is supposed to make sure that scmconfig.h is
+	built before all sources in order to prevent that everything has
+	to be rebuilt again.  Hope it works---I'm just guessing. :)
+
+	* fluids.c (scm_fluid_set_x): Return SCM_UNSPECIFIED.
+
+2000-08-23  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
+
+	* gc.c (scm_gc_mark): Don't use GUILE_DEBUG flag to compile in

+	debugging functions available.)
+
+2000-08-21  Michael Livshin  <mlivshin@bigfoot.com>
+
+	* gc.h (SCM_GC_CARD_N_CELLS): change to be a nice non-confusing

+	* gc.c (scm_gc_sweep): added a `continue' statement that have
+ 	fallen through the cracks in the merge.  thanks to Shuji Narazaki!
+
+	* gc.h: removed some stuff that broke compilation for people and
+ 	wasn't actually needed anyway.
+
+2000-08-18  Neil Jerram  <neil@ossau.uklinux.net>
+
+	* filesys.c (scm_fcntl): Docstring fix - missing newlines inserted.
+

+
+	this changes the Guile GC to use cards (aka "chunklets").
+	(most of the ideas and some of the code are by Greg Harvey, though
+	the code is probably unrecognizable now.  the original chunklet
+	proposal, way back, is by Dale Jordan).
+
+	* tags.h: (SCM_GCTYPE16, SCM_GCCDR, SCM_GC[8]MARKP,
+	SCM_SETGC[8]MARK, SCM_CLRGC[8]MARK): moved from here into gc.h.
+	some (most) of these are probably going to be deprecated.
+
+	* gc.h (SCM_MARKEDP): simplified, there are no different mark bit
+	locations anymore.
+	(SCM_GC_CARD_*, SCM_C_BVEC_*): lots of new macros to deal with
+	cards and bvecs (bit-vectors).
+
+	* gc.c: (scm_default_init_heap_size_*): defined to take cards into
+ 	account, but keeping more or less the same values as previously.
+  	added some simple helper macros.
+	(CLUSTER_SIZE_IN_BYTES, ALIGNMENT_SLACK): defined to take cards
+ 	into account.

+	and macros that implement mark space management.
+	(scm_igc): clear the mark space (all of it) before beginning the
+	mark phase.
+	(scm_gc_mark): changed the tests for rogue cells, much simplified
+	throughout (no different mark bit locations to worry about now).
+	(scm_mark_locations): don't consider card header cells.
+	(scm_cellp): ditto.
+	(scm_gc_sweep): simplified.
+	(init_heap_seg): changed to take cards into account.
+
+2000-08-16  Michael Livshin  <mlivshin@bigfoot.com>
+
+	* stime.c (scm_c_get_internal_run_time): new function, same as
+ 	scm_get_internal_run_time but returns a long.  it's used by the GC
+ 	for timekeeping, since with scm_get_internal_run_time there is a
+ 	(extremely theoretical) possibility of consing.
+	(scm_get_internal_run_time): redefined in terms of
+ 	scm_c_get_internal_run_time.
+
+	* stime.h: added prototype for scm_c_get_internal_run_time.
+
+	* gc.c (scm_gc_stats): add more obscure stats, such as: mark time,
+ 	sweep time, total marked cells, total swept cells, and number of
+ 	times GC was invoked.
+	(gc_start_stats): renamed from scm_gc_start, made static, taught
+ 	to init the new stats.
+	(gc_end_stats): renamed from scm_gc_end, made static, taught to
+ 	calculate the new stats.
+	(scm_igc): don't call gc_start_stats unless we are sure that we
+ 	are indeed going to collect.  also, added some timekeeping between
+ 	the mark and sweep phases.
+	(scm_gc_sweep): count number of cells we sweep as we go.
+
+	* gc.h: removed prototypes for scm_gc_{start,end}.

+
+	* alist.c (scm_assq, scm_assv, scm_assoc): Report argument type
+	error for the alist rather than the sublist where the type
+	mismatch is discovered.
+
+2000-08-13  Neil Jerram  <neil@ossau.uklinux.net>

+
+	* eval.c (scm_eval): Backward incompatible change: Now takes an
+	environment specifier as second arg.  `eval' hereby becomes R5RS
+	compatible.
+	(scm_i_eval_x, scm_i_eval): New functions (replace
+	scm_eval_3).

+	to new scm_eval_x.
+
+	* load.c (load): Use `scm_selected_module' to compute second arg
+	to new scm_i_eval_x; Don't call it if module system hasn't booted.
+	(scm_read_and_eval_x): Deprecated.
+	#include "modules.h".
+
+	* debug.c (scm_local_eval): Use scm_i_eval and scm_i_eval_x.

+
+2000-08-09  Mikael Djurfeldt  <mdj@linnaeus.mit.edu>
+
+	The following changes are intended to ensure that struct instances
+	are freed before their vtables.  It's optimized for the most

+
+	* gc.c (scm_gc_mark, scm_gc_sweep): Remove vcell = 1 magic.
+	(scm_structs_to_free): New variable.

+	(scm_struct_prehistory): Install them.
+
+	* init.c (scm_boot_guile_1): Call scm_struct_prehistory.

+
+	* iselect.c: Include <unistd.h>.  Thanks to Bertrand Petit!
+
+2000-08-02  Mikael Djurfeldt  <mdj@linnaeus.mit.edu>
+
+	* struct.c (scm_make_struct_layout, scm_make_struct,
+	scm_make_vtable_vtable): Updated documentation.
+
+	* print.c (scm_simple_format): Bugfix: Coerce port before using

+	(thanks to Richard Kim for the bug report).
+
+2000-07-30  Marius Vollmer  <mvo@zagadka.ping.de>
+
+	* alist.c (scm_assq_remove_x, scm_assv_remove_x,
+	scm_assoc_remove_x): Use scm_delq1_x instead of scm_delq_x, since
+	using the latter is pointless.
+
+2000-07-26  Dirk Herrmann  <D.Herrmann@tu-bs.de>
+
+	* gc.c (scm_gc_sweep):  Renamed local variable from 'free' to
+	'free_struct_data' to avoid confusion with stdlib's 'free'.
+
+2000-07-26  Dirk Herrmann  <D.Herrmann@tu-bs.de>
+
+	* vectors.c (scm_make_vector):  Fix the initialization order of
+	the vector such that the type cell is initialized last.
+
+2000-07-26  Dirk Herrmann  <D.Herrmann@tu-bs.de>
+
+	* struct.[ch] (scm_struct_init):  Made static.  Fixed not to rely
+	on the struct cell to be fully initialized.
+
+	* struct.c (scm_make_struct, scm_make_vtable_vtable):  Fix the
+	initialization order of the struct such that the type cell is
+	initialized last.
+
+2000-07-25  Marius Vollmer  <mvo@zagadka.ping.de>
+
+	* alist.c (scm_assq_remove_x, scm_assv_remove_x,

+
+2000-07-24  Marius Vollmer  <mvo@zagadka.ping.de>
+
+	* stime.c (scm_strftime): Recognize a return value of zero from
+	strftime as buffer overflow and take care to detect a valid zero
+	length result regardless.  Thanks to David Barts!
+
+2000-07-23  Marius Vollmer  <mvo@zagadka.ping.de>
+
+	* alist.c (scm_assq_remove_x, scm_assv_remove_x,
+	scm_assoc_remove_x): Remove all cells whose key is eq, eqv, or
+	equal (respectively) to the argument key, not all cells that are
+	eq, eqv, or equal to the first cell with the argument key.  Thanks
+	to Neil Jerram!
+
+2000-07-18  Dirk Herrmann  <D.Herrmann@tu-bs.de>
+
+	* gc.h (SCM_FREE_CELL_CDR, SCM_SET_FREE_CELL_CDR), hooks.c
+	(make_hook), modules.c (OBARRAY, USES, BINDER):  Pack and unpack
+	SCM values appropriately.
+
+	* modules.c (scm_standard_eval_closure):  Don't pass an inum to
+	scm_makcclo, but rather a long value.
+
+2000-07-18  Dirk Herrmann  <D.Herrmann@tu-bs.de>
+
+	read.c (scm_lreadrecparen), srcprop.c (scm_set_source_property_x):
+	SCM_SETCDR and SCM_WHASHSET macros don't deliver a return value.
+	Thanks to Han-Wen Nienhuys for the bug report.
+
+2000-07-18  Dirk Herrmann  <D.Herrmann@tu-bs.de>
+
+	* root.[ch] (scm_call_catching_errors):  Deprecated.
+

+	standard initialization functions.
+
+2000-07-17  Marius Vollmer  <mvo@zagadka.ping.de>
+
+	* eval.c (unmemocopy): Don't rely on V being a list of at least
+	one element.  Thanks to Bill Schottstaedt!
+
+2000-07-15  Michael Livshin  <mlivshin@bigfoot.com>
+
+	* gc.c (scm_done_free): new.
+	expanded comments about scm_done_malloc.
+
+	* gc.h: added prototype for scm_done_free
+
+2000-07-13  Dirk Herrmann  <D.Herrmann@tu-bs.de>
+
+	* gc.h (scm_take_stdin):  Removed.
+
+	* gc.h (SCM_VALIDATE_CELL):  Delegate cell checks to function
+	scm_assert_cell_valid to allow extensions to the checking
+	functionality without need to recompile everything.
+
+	* gc.[ch] (scm_assert_cell_valid, scm_set_debug_cell_accesses_x):
+	Added as conditionally compiled functions for the case that
+	SCM_DEBUG_CELL_ACCESSES is enabled.
+
+	* gc.c (debug_cells_p):  Added to indicate whether compile-time
+	included cell access debugging is run-time enabled.
+
+	* gc.[ch] (scm_gc_running_p):  Added to indicate that scm_igc is
+	being executed.  Intended to be used instead of scm_gc_heap_lock
+	at most places.
+
+	* error.c (scm_error), gdbint.c (SCM_GC_P):  Use scm_gc_running_p
+	instead of scm_gc_heap_lock.
+
+	* gc.c (scm_igc):  Set scm_gc_running_p to true while running.
+
+	* gc.c (scm_mark_locations):  Don't mark free cells.
+
+	* weaks.c (scm_scan_weak_vectors):  Use SCM_FREE_CELL_P instead of
+	SCM_FREEP.
+
+2000-07-13  Dirk Herrmann  <D.Herrmann@tu-bs.de>
+
+	* gc.c (scm_mark_locations):  Minimized some variable scopes and
+	simplified the code a bit.
+
+2000-07-10  Dirk Herrmann  <D.Herrmann@tu-bs.de>
+
+	* gc.h (SCM_SET_FREE_CELL_TYPE, SCM_SET_FREE_CELL_CDR,
+	SCM_FREE_CELL_P, SCM_FREE_CELL_CDR):  Added since free cells
+	should not be accessed via SCM_C[AD]R.  Further, using dedicated
+	macros to access free cells allows all other cell accessing macros
+	to treat acesses to free cells as errors, thus enabling better
+	error checks for cell accesses.  SCM_FREE_CELL_P is supposed to
+	replace SCM_FREEP some time.
+
+	* gc.h (SCM_NEWCELL, SCM_NEWCELL2), gc.c (map_free_list,
+	free_list_length, scm_check_freelist, scm_debug_newcell,
+	scm_debug_newcell2, freelist_length, scm_gc_for_newcell,
+	scm_gc_mark, scm_gc_sweep, init_heap_seg):  Only use the dedicated
+	cell accessors when accessing free cells.
+
+2000-07-10  Dirk Herrmann  <D.Herrmann@tu-bs.de>
+
+	* gc.h (SCM_CELL_WORD, SCM_CELL_OBJECT):  Treat the referenced
+	object as const in order to make the compiler warn about code like
+	SCM_CELL_WORD (x, n) = y.  Instead, SCM_SET_CELL_WORD (x, n, y)
+	should be used.
+
+	(SCM_CELL_WORD_LOC, SCM_CARLOC, SCM_CDRLOC):  Return the address
+	as an address to a non-const object, since these macros are used
+	to allow direct write access to objects.
+
+2000-07-07  Dirk Herrmann  <D.Herrmann@tu-bs.de>
+
+	* hashtab.c (scm_hash_fn_create_handle_x):  Signal an error if the
+	given hash table has no slots.
+
+2000-07-06  Dirk Herrmann  <D.Herrmann@tu-bs.de>
+
+	* gc.c (policy_on_error):  Added in order to allow alloc_some_heap
+	to react to malloc failures in a context dependent way.
+
+	(scm_check_freelist):  No need to flush streams before abort().
+
+	(scm_gc_for_newcell):  Try to allocate new memory in three phases:
+	grow heap if preferred, if still no memory available collect
+	garbage, if still no memory available grow heap.
+
+	(heap_segment_table_size):  Added to always reflect the actual
+	size of the heap segment table, because scm_n_heap_segs may differ
+	from the heap segment table size.
+
+	(alloc_some_heap):  In case of malloc failure, react according to
+	the new policy_on_error parameter (either return to caller or
+	abort immediately).  Further, keep heap_segment_table_size up to
+	date.
+
+	(scm_init_storage):  Initialize heap_segment_table_size.
+
+2000-07-06  Dirk Herrmann  <D.Herrmann@tu-bs.de>
+
+	* gh.h:  Don't include <stdio.h>.  Thanks to Han-Wen Nienhuys for
+	the hint.
+
+2000-06-30  Dirk Herrmann  <D.Herrmann@tu-bs.de>
+
+	* __scm.h (SCM_OUTOFRANGE, SCM_NALLOC, SCM_HUP_SIGNAL,
+	SCM_INT_SIGNAL, SCM_FPE_SIGNAL, SCM_BUS_SIGNAL, SCM_SEGV_SIGNAL,
+	SCM_ALRM_SIGNAL, SCM_GC_SIGNAL, SCM_TICK_SIGNAL, SCM_SIG_ORD,
+	SCM_ORD_SIG, SCM_NUM_SIGS):  Re-introduce these as deprecated
+	symbols.
+
+	* error.c (scm_wta):  Re-introduce dispatching for SCM_OUTOFRANGE
+	and SCM_NALLOC, but as a deprecated feature.
+
+2000-06-30  Mikael Djurfeldt  <mdj@thalamus.nada.kth.se>
+
+	* debug.c: Added #include fluids.h.
+
+	* numbers.c (scm_gr_p, scm_leq_p, scm_geq_p): Turned into
+	primitive generics.  (Thanks to Nicolas Neuss.)
+
+2000-06-30  Dirk Herrmann  <D.Herrmann@tu-bs.de>
+
+	* gc.c (alloc_some_heap):  Use scm_memory_error to indicate a
+	failed attempt to get additional memory from the system.
+
+	(scm_gc_for_newcell):  Changed the control structure to make the
+	behaviour explicit for the case that gc is not able to free any
+	cells.
+
+2000-06-30  Dirk Herrmann  <D.Herrmann@tu-bs.de>
+
+	* __scm.h (SCM_OUTOFRANGE):  Removed.
+
+	* error.c (scm_wta):  Removed sick dispatch code for range
+	errors.  (More sick dispatches still to be removed.)
+
+	* hashtab.c (scm_hash_fn_get_handle, scm_hash_fn_create_handle_x,
+	scm_hash_fn_remove_x):  Eliminate redundant test for if unsigned
+	value is non-negative.  Use scm_out_of_range to signal range
+	errors.
+
+	* hooks.c (make_hook), unif.c (scm_aind):  Use scm_out_of_range to
+	signal range errors.
+
+	* list.c (scm_list_ref, scm_list_set_x, scm_list_cdr_set_x):  Fix
+	error reporting (now uses original input parameter to report wrong
+	type argument errors).  Use SCM_OUT_OF_RANGE to report range
+	errors and SCM_WRONG_TYPE_ARG to report type errors.
+
+	* strings.c (scm_substring):  Make range checks for negative
+	values explicit (former behaviour relied on an implicit
+	conversion from signed to unsigned).  Don't use SCM_ASSERT for
+	range checks.
+
+	* unif.c (scm_aind, scm_transpose_array, scm_bit_set_star_x,
+	scm_bit_count_star):  Use scm_out_of_range to signal range
+	errors.
+
+	* unif.c (scm_transpose_array, scm_bit_position), vectors.c
+	(scm_vector_ref, scm_vector_set_x, scm_vector_move_left_x,
+	scm_vector_move_right_x):  Use SCM_ASSERT_RANGE to check ranges.
+
+2000-06-30  Dirk Herrmann  <D.Herrmann@tu-bs.de>
+
+	* validate.h (SCM_VALIDATE_INUM_MIN_COPY,
+	SCM_VALIDATE_INUM_MIN_DEF_COPY, SCM_VALIDATE_INUM_RANGE_COPY):
+	Perform all range checks based on the input value.  The former way
+	of using the value that is assigned to the target variable fails
+	if the assignment to the target variable itself can change the
+	value because of type conversion.
+
+	(SCM_ASSERT_RANGE):  Use scm_out_of_range to signal range errors.
+
+2000-06-30  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
+
+	* gc.c (scm_gc_for_newcell): Behave gracefully also if scm_igc
+	doesn't yield any new cells.  In theory this could happen if all
+	cells allocated with NEWCELL are either in use or conservatively
+	marked and all cluster spine cells are conservatively marked.
+	(Thanks to Dirk.)
+
+2000-06-29  Dirk Herrmann  <D.Herrmann@tu-bs.de>
+
+	* __scm.h (SCM_NALLOC):  Removed.

+
+	* gc.c (scm_gc_mark, scm_gc_sweep, scm_must_malloc,

+
+2000-06-28  Michael Livshin  <mlivshin@bigfoot.com>

+	allocate instead.
+
+2000-06-28  Dirk Herrmann  <D.Herrmann@tu-bs.de>
+
+	* async.c (scm_gc_async, scm_gc_vcell, scm_sys_gc_async_thunk):
+	Moved to gc.c.
+
+	(scm_init_async):  Moved initialization for scm_gc_async and
+	scm_gc_vcell to gc.c.  Moved initialization of scm_asyncs here
+	from gc.c.
+
+	* async.h (scm_gc_async):  Not globally visible any more.
+
+	* gc.c (scm_gc_stats):  Made callable even from within regions
+	where gc is blocked.
+
+	(scm_gc_end):  Eliminate the hardcoding of the marking of the
+	scm_gc_async from the gc core.
+
+	(scm_init_storage):  Don't initialize the scm_asyncs list here.
+	This is now done in asyncs.c.
+
+	(scm_gc_vcell):  Moved here from async.c.
+
+	(gc_async):  Renamed from scm_gc_async, moved here from async.c
+	and made static.
+
+	(gc_async_thunk):  Renamed from scm_sys_gc_async_thunk and moved
+	here from async.c.
+
+	(mark_gc_async):  New hook function for scm_after_gc_c_hook.
+
+	(scm_init_gc):  Added initialization of scm_gc_vcell and
+	gc_async.  Further, add mark_gc_async to scm_after_gc_c_hook.
+
+	* init.c (scm_boot_guile_1):  scm_init_gc requires asyncs to be
+	initialized.
+
+2000-06-28  Dirk Herrmann  <D.Herrmann@tu-bs.de>
+
+	* gc.c (scm_igc):  Removed commented code that once was intended
+	to unprotect struct types with no instances.
+
+	* root.h (scm_type_obj_list):  Removed.
+
+2000-06-27  Dirk Herrmann  <D.Herrmann@tu-bs.de>
+
+	* async.c (scm_init_async):  Switch to standard way of smob
+	initialization.
+
+2000-06-21  Michael Livshin  <mlivshin@bigfoot.com>
+
+	* guile-doc-snarf.in: use cut instead of sed, that's much much
+	faster.  also, don't call basename more than needed.  and, to gain
+	a couple of microseconds more, don't call cat needlessly.  (thanks
+	to Brad Knotwell).
+
+2000-06-21  Dirk Herrmann  <D.Herrmann@tu-bs.de>
+
+	* guile-snarf.awk.in, guile-snarf.in, snarf.h:  Rename SCM__I to
+	SCM_SNARF_INIT_START, SCM__D to SCM_SNARF_DOC_START, SCM__S to
+	SCM_SNARF_DOCSTRING_START and SCM__E to SCM_SNARF_DOCSTRING_END.
+
+2000-06-21  Mikael Djurfeldt  <mdj@thalamus.nada.kth.se>
+
+	* eval.c, eval.h (scm_top_level_lookup_closure_var): Added.
+	#include "libguile/fluids.h".
+
+	* eval.h (SCM_TOP_LEVEL_LOOKUP_CLOSURE): New macro which replaces
+	SCM_CDR (scm_top_level_lookup_closure_var) everywhere.
+
+	* root.h (scm_top_level_lookup_closure_var,
+	scm_system_transformer): Removed.  (It's no sense in having the
+	*variable* be a "fluid".)
+
+	* root.c (mark_root): Removed marking of
+	s->top_level_lookup_closure_var and s->system_transformer.
+
+	* modules.c (scm_selected_module): the_module is now a fluid.
+
+2000-06-20  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
+
+	* gc.h, tags.h: Be kind to compilers which must see hash signs in
+	column 0.  (Thanks to Ian Grant.)
+
+	* numbers.h: Put #ifdef HAVE_LONG_LONGS around declarations using
+	the long_long type.  (Thanks to Bernard Urban.)
+
+2000-06-20  Mikael Djurfeldt  <mdj@thalamus.nada.kth.se>
+
+	* gc.c, gc.h (scm_default_init_heap_size_1,
+	scm_default_min_yield_1, scm_default_init_heap_size_2,
+	scm_default_min_yield_2, scm_default_max_segment_size): New global
+	variables.  Can be customized by the application before booting
+	Guile.  (We might want to be able to control these parameters
+	dynamically through the "options interface" in the future, but
+	note that that is additional functionality.  Here we're giving
+	default values which the environment variables can override.)
+
+	* list.c (scm_cons_star): Updated comment.
+
+	* smob.h: Changed comments for scm_make_smob_type and
+	scm_make_smob_type_mfpe, warning that the latter might be
+	deprecated in a future release.
+
+2000-06-19  Dirk Herrmann  <D.Herrmann@tu-bs.de>
+
+	* list.[ch] (scm_cons_star/cons*):  Renamed from
+	scm_list_star/list*.
+
+	* list.[ch] (scm_list_star/list*):  Provided as a deprecated alias
+	for scm_cons_star/cons*.
+
+	* gc.c (scm_protect_object):  Updated comment.
+
+	* numbers.h (SCM_NEWREAL, SCM_NEWCOMPLEX):  Removed.
+
+	* tags.h (SCM_UNPACK_CAR, SCM_NDOUBLE_CELLP):  Removed.
+
+2000-06-19  Mikael Djurfeldt  <mdj@thalamus.nada.kth.se>
+
+	* init.c, init.h (scm_initialized_p): Renamed from `initialized'
+	and made global.
+
+	* gdbint.c (gdb_print): Print warning instead of calling scm_write
+	if Guile isn't yet initialized.
+
+	* print.c (scm_current_pstate, scm_make_print_state): Simplified
+	tests, using the assumption that Guile has been initialized.
+
+Sun Jun 18 14:45:21 2000  Greg J. Badros  <gjb@cs.washington.edu>
+
+	* print.c (s_scm_current_pstate): Do not segfault when the
+	print_state_pool is unitialized in `current-pstate', and better
+	verify its state before altering it in scm_make_print_state().
+
+2000-06-18  Michael Livshin  <mlivshin@bigfoot.com>
+
+	* scmsigs.c (s_scm_sigaction): guard the SIGIOT case with an
+ 	#ifdef -- it's missing on at least one platform.  (thanks to
+ 	Jan Nieuwenhuizen).
+
+2000-06-16  Dirk Herrmann  <D.Herrmann@tu-bs.de>
+
+	* list.c (list*):  Added documentation from common-list.scm.
+
+2000-06-15  Dirk Herrmann  <D.Herrmann@tu-bs.de>
+
+	* gc.c (scm_unprotect_object):  The reference count is guaranteed
+	to be a positive number.
+
+2000-06-15  Mikael Djurfeldt  <mdj@thalamus.nada.kth.se>
+
+	* eval.c: Updated comment above scm_map.
+
+2000-06-14  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
+
+	* gc.c (scm_protect_object): Avoid looking up the object handle
+	twice.
+	(scm_unprotect_object): Abort if scm_unprotect_object is called on
+	an unprotected object.
+
+2000-06-14  Michael Livshin  <mlivshin@bigfoot.com>
+
+	* gc.c (scm_unprotect_object): fix a nasty typo bug (thanks to
+ 	Dirk Herrmann).
+
+2000-06-14  Mikael Djurfeldt  <mdj@thalamus.nada.kth.se>
+
+	* socket.c (scm_getsockopt): Changed type for `optlen' from int to
+	size_t.
+	(scm_accept, scm_getsockname, scm_getpeername, scm_recvfrom):
+	Ditto for `tmp_size'.
+	(scm_addr_buffer_size): Changed type from int to size_t.
+
+	* random.c: #include <string.h>.  (Needed by memcpy.)
+
+	* guile-snarf.awk.in: Replace the dot_doc_file arg with "-",
+	indicating stdin, instead of "" and don't reset ARGC.  This is a
+	workaround for `nawk' in AIX 4.3 on RS6000 but, as far as I know,
+	it is correct, and perhaps even better.
+
+2000-06-14  Gary Houston  <ghouston@arglist.com>
+
+	* scmsigs.c (scm_init_scmsigs): if HAVE_SIGINTERRUPT is not
+	defined, add SA_RESTART to the sigaction flags correctly
+	(thanks to Dale P. Smith).
+
+2000-06-13  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
+
+	* strings.c: #include <string.h>. (Thanks to Bill Schottstaedt.)
+
+	* net_db.c (scm_resolv_error): Only use macro NETDB_INTERNAL if
+	defined. It isn't on sgi irix 5.3.  (Thanks to Bill Schottstaedt.)
+
+	* Makefile.am (.c.doc): Pipe output (the .x contents) to /dev/null.
+
+2000-06-13  Mikael Djurfeldt  <mdj@thalamus.nada.kth.se>
+
+	* fports.c (scm_setvbuf): Use `free' instead of `scm_must_free'
+	since read and write buffers are allocated by `malloc'.
+
+	* Makefile.am: Removed old test code.
+
+	* gh_test_c.c, gh_test_repl.c: Removed.
+
+2000-06-12  Mikael Djurfeldt  <mdj@thalamus.nada.kth.se>
+
+	* iselect.c (SCM_NLONGBITS): Add workaround for the Sun 4.2
+	compiler.
+
+	* inet_aton.c (inet_aton): Cast init value for `cp'.
+
+	* ramap.c (s_scm_array_fill_x): Cast `ve' properly in case
+	`scm_tc7_uvect'.
+
+	* symbols.c (scm_intern_obarray_soft,
+	scm_sysintern0_no_module_lookup): Cast `name' to unsigned char ptr
+	in calls to scm_strhash.
+
+	* strports.c (st_resize_port): Substituted SCM_UCHARS for
+	SCM_CHARS.
+	(st_write): Cast argument to strncpy to char ptr.
+	(scm_mkstrport): Substituted SCM_ROUCHARS for SCM_ROCHARS.
+	(scm_strport_to_string): Cast argument to scm_makfromstr to char
+	ptr.
+
+	* ports.c (scm_ungetc): Cast value to unsigned char ptr before
+	storing in putback_buf.
+	(scm_unread_string): Substituted SCM_ROCHARS for SCM_ROUCHARS.
+
+	* ioext.c (s_scm_read_line): Cast result of call to
+	scm_do_read_line to unsigned char ptr.
+
+	* gdbint.c (SEND_STRING): Cast argument to char pointer.
+
+	* fports.c (fport_flush): Declare `ptr' as unsigned char (was
+	char).
+
+	* Makefile.am (DOT_DOC_FILES): List doc-files explicitly.  (We
+	shouldn't use Make rules which aren't supported by most Make
+	programs.)
+	(OMIT_DEPENDENCIES): Defined to "libguile.h ltdl.h".  (We don't
+	want these dependencies recorded, since they would get bogus
+	relative paths; libguile.h is only used in gh.h and guile.c.)
+	(EXTRA_DOT_X_FILES, EXTRA_DOT_DOC_FILES): New variables.
+	(guile-procedures.txt): Depend on EXTRA_DOT_DOC_FILES.
+	(modinclude_HEADERS): Removed kw.h.
+
+	* guile-snarf.in: Change regexp "^SCM__I" --> "^ *SCM__I".
+	(The preprocessor might insert spaces before the identifier.)
+
+	* snarf.h (SCM_SNARF_HERE, SCM_SNARF_INIT, SCM_SNARF_DOCS):
+	Renamed from SCM_HERE, SCM_INIT, SCM_DOCS.
+
+	* smob.h (scm_smobfuns): Removed deprecated type.
+
+	* smob.c, smob.h (scm_newsmob): Removed deprecated function.
+	(Replaced by `scm_make_smob_type'.)
+
+	* keywords.c (scm_tc16_kw): Removed deprecated type.
+	(Replaced by scm_tc16_keyword.)
+
+	* kw.h: Removed deprecated header file.
+
+	* evalext.c (serial-map): Removed deprected alias for scm_map.
+	(Has been replaced by `map-in-order'.)
+
+	* ramap.c (serial-array-copy!, serial-array-map!): Removed
+	depracted aliases.  (Replaced by `array-copy-in-order!' and
+	`array-map-in-order'.)
+
+2000-06-11  Mikael Djurfeldt  <mdj@thalamus.nada.kth.se>
+
+	* gc.h (SCM_VALIDATE_CELL): Rewritten.
+	(SCM_CELL_WORD, SCM_CELL_OBJECT, SCM_SET_CELL_WORD,
+	SCM_SET_CELL_OBJECT): Use new version of SCM_VALIDATE_CELL.
+	(Thanks to Han-Wen Nienhuys.)
+
+2000-06-10  Michael Livshin  <mlivshin@bigfoot.com>
+
+	* guile-doc-snarf.in: don't pipe the CPP output right into sed --
+ 	write it to the temp file first and check the CPP return code.
+	(I introduced this bug earlier, and this probably caused people
+ 	with non-GNU C preprocessors to get empty *.x files and not to
+ 	have the build fail right away...).
+
+	* scmsigs.c (s_scm_sigaction): guard the SIGSYS case with an ifdef
+ 	-- at least my libc5-based Linux system doesn't define SIGSYS.
+
+2000-06-08  Mikael Djurfeldt  <mdj@thalamus.nada.kth.se>
+
+	* snarf.h, guile-snarf.awk.in, guile-snarf.in: Replaced snarf
+	markers with identifiers (SCM__I, SCM__D, SCM__S, SCM__E).
+	(Thanks to Bernard Urban.)
+
+2000-06-06  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
+
+	* modules.c (scm_system_module_env_p): Fixed detection of system
+	modules.
+
+2000-06-06  Marius Vollmer  <mvo@zagadka.ping.de>
+
+	* scmsigs.c (scm_sigaction): Silently ignore setting handlers for
+	`program error signals' because they can't currently be handled by
+	Scheme code.
+
+2000-06-05  Dirk Herrmann  <D.Herrmann@tu-bs.de>
+
+	* procs.h (SCM_SET_SUBRF):  Added.
+
+	* procs.c (scm_make_subr_opt):  Don't assign to SCM_SUBRF, use
+	SCM_SET_SUBRF instead.  Thanks to Bernard Urban for the bug
+	report.
+
+2000-06-05  Dirk Herrmann  <D.Herrmann@tu-bs.de>
+
+	* gc.h (SCM_CARLOC, SCM_CDRLOC):  Don't take the address of a SCM
+	value.
+
+	* sort.c (scm_sorted_p, scm_merge, scm_merge_list_x,
+	scm_merge_list_step):  Don't take the address of SCM_CAR.  Use
+	SCM_CARLOC instead.  Thanks to Bernard Urban for the bug report.
+
+2000-06-05  Dirk Herrmann  <D.Herrmann@tu-bs.de>
+
+	* boolean.h (SCM_TRUE_P):  Removed, as people might use it as a
+	replacement for !SCM_FALSEP.
+
+	* backtrace.c (display_error_body), boolean.h (SCM_BOOLP), gc.c
+	(scm_unhash_name), gh_data.c (gh_module_lookup), load.c
+	(scm_primitive_load), print.c (scm_simple_format), procs.c
+	(scm_procedure_documentation), procs.h (SCM_TOP_LEVEL), ramap.c
+	(scm_array_fill_int), scmsigs.c (scm_sigaction), stacks.c
+	(narrow_stack, scm_make_stack, scm_stack_id), symbols.c
+	(scm_string_to_obarray_symbol), throw.c (scm_catch,
+	scm_lazy_catch, scm_ithrow), unif.c (scm_make_uve, scm_array_p,
+	scm_array_set_x, scm_bit_set_star_x, scm_bit_count_star),
+	validate.h (SCM_VALIDATE_BOOL_COPY, SCM_VALIDATE_PROC):  Replace
+	uses of SCM_TRUE_P (x) with SCM_EQ_P (x, SCM_BOOL_T).
+
+2000-06-04  Mikael Djurfeldt  <mdj@thalamus.nada.kth.se>
+
+	* eval.c (scm_badformalsp): New static function.
+	(SCM_CEVAL): Check arguments for procedure-with-setter closures.
+	(Thanks to Keisuke Nishida.)
+
+	The major reason for Guile's slow loading speed has been the fact
+	that a chain of Scheme level procedures has been evaluated for
+	every top-level symbol lookup during the first pass through the
+	code.
+
+	The following is a kludge which I suggested four years ago, and
+	which I've repeatedly suggested since.  Personally, I've never
+	been bothered by Guile's slow loading speed, so I thought I would
+	let someone else do it...
+
+	But since the new environments will be included first in
+	Guile-1.5, I thought it would make people happy to get the kludge
+	into 1.4.
+
+	* modules.c: Added #include "libguile/vectors.h";
+	Added #include "libguile/hashtab.h";
+	Added #include "libguile/struct.h";
+	Added #include "libguile/variable.h";
+	Capture Scheme level `module-make-local-var!' to be used in the
+	standard eval closure.
+	(scm_standard_eval_closure): New primitive.
+
+	* modules.h (scm_standard_eval_closure): Declare.
+
+	* eval.c (scm_lookupcar): Test for !SCM_CONSP (SCM_CAR (env))
+	instead of SCM_TRUE (scm_procedurep (SCM_CAR (env))).
+
+	* symbols.c (scm_sym2vcell): Bypass dispatch in the evaluator for
+	standard eval closures.
+
+	* variable.c: Code layout fixes.
+
+2000-06-03  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
+
+	* Makefile.am: Added LIBS line to libpath which accidentally
+	disappeared in the change of 2000-06-01.
+	(Thanks to Dale	P. Smith.)
+
+2000-06-03  Mikael Djurfeldt  <mdj@thalamus.nada.kth.se>
+
+	* scmsigs.c (scm_segfault): Removed.  (Was probably added by
+	mistake since it is not mentioned in ChangeLog.)
+
+	* gc.h (SCM_VALIDATE_CELL): Cast result to (void) in order to
+	avoid compiler warnings in gcc.  (Does this work for other
+	compilers?)
+
+2000-06-03  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
+
+	* gc.h (SCM_VALIDATE_CELL): Don't "use" the value returned by
+	abort ().
+	(SCM_CARLOC, SCM_CDRLOC): Define directly instead of using
+	SCM_CELL_OBJECT_0 and SCM_CELL_OBJECT_1.  It's not correct to take
+	the address of these expressions since they use SCM_VALIDATE_CELL.
+	(Thanks to Bernard Urban.)
+
+	* dynl.c: Changed #include <ltdl.h> --> #include
+	"libltdl/ltdl.h".  (Thanks to Bill Schottstaedt.)
+
+2000-06-01  Craig Brozefsky  <craig@red-bean.com>
+
+	* Makefile.am: libguile_la_LDFLAGS gets -version-info args
+	from GUILE-VERSION definition of LIBGUILE version.  Added to
+	libpath.h definitions for guileversion and libguileversion which
+	both get their values from GUILE-VERSION definition.
+
+2000-05-30  Dirk Herrmann  <D.Herrmann@tu-bs.de>
+
+	* numbers.h (SCM_BIGP):  Don't use SCM_SMOB_PREDICATE in header
+	file:  Code using numbers should not be required to include
+	smob.h.
+
+2000-05-30  Dirk Herrmann  <D.Herrmann@tu-bs.de>
+
+	* coop-threads.c.cygnus, coop-threads.h.cygnus, fsu-pthreads.h,
+	mit-pthreads.c, mit-pthreads.h:  Deleted.
+
+	* Makefile.am (EXTRA_DIST), scmsigs.c, threads.[ch]:  Drop
+	references to deleted files and fsu/mit thread support in
+	general.
+
+2000-05-29  Dirk Herrmann  <D.Herrmann@tu-bs.de>
+
+	* hooks.c (symbol_name, scm_create_hook):  Restored the original
+	behaviour of scm_create_hook.  Changing it was bad as Carl
+	R. Witty has pointed out.
+
+	* gc.c (scm_init_gc):  We can still rely on scm_create_hook to
+	protect the object.
+
+2000-05-26  Dirk Herrmann  <D.Herrmann@tu-bs.de>
+
+	* gc.c (scm_init_gc):  Protect scm_after_gc_hook, since this will
+	soon not be done by scm_create_hook any longer.
+
+	* hooks.c (make_hook, print_hook, scm_create_hook,
+	scm_make_hook_with_name, scm_make_hook), hooks.h (SCM_HOOK_NAME,
+	SCM_HOOK_PROCEDURES, SCM_SET_HOOK_PROCEDURES,
+	scm_make_hook_with_name), init.c (scm_boot_guile_1):  Hooks no
+	longer have names.  As an intermediate solution, the name
+	predicate is emulated via object properties, but use of this
+	feature is deprecated.
+
+	* hooks.h (scm_free_hook):  Removed, as it is never defined.
+
+2000-05-25  Dirk Herrmann  <D.Herrmann@tu-bs.de>
+
+	* numbers.[ch] (SCM_POSFIXABLE, SCM_NEGFIXABLE, SCM_FIXABLE):
+	Un-deprecated since otherwise user code can't determine whether a
+	number fits into an inum any longer.  The names should be changed
+	some time, though.
+
+	* numbers.c (scm_big2inum):  Eliminated use of SCM_UNEGFIXABLE.
+
+	* tags.h (SCM_UNPACK_CAR):  Deprecated.
+
+2000-05-25  Dirk Herrmann  <D.Herrmann@tu-bs.de>
+
+	* filesys.h (SCM_OPDIRP), fluids.h (SCM_FLUIDP, SCM_FLUID_NUM),
+	fports.h (SCM_OPFPORTP, SCM_OPINFPORTP, SCM_OPOUTFPORTP), hooks.h
+	(SCM_HOOK_ARITY), keywords.h (SCM_KEYWORDP, SCM_KEYWORDSYM),
+	numbers.h (SCM_NUMP, SCM_BIGSIGN, SCM_BDIGITS, SCM_NUMDIGS):
+	Replace SCM_UNPACK_CAR appropriately.  Don't access cells via
+	SCM_{SET}?C[AD]R unless they are known to be cons cells.
+
+	* gc.c (scm_heap_seg_data_t, scm_mark_locations, scm_cellp,
+	init_heap_seg):  Remove unused struct member variable 'valid'.
+
+2000-05-24  Dirk Herrmann  <D.Herrmann@tu-bs.de>
+
+	* fports.c (fport_write), ports.c (scm_markstream, scm_port_mode,
+	scm_print_port_mode), ports.h (SCM_OPPORTP, SCM_OPINPORTP,
+	SCM_OPOUTPORTP, SCM_INPUT_PORT_P, SCM_OUTPUT_PORT_P, SCM_OPENP),
+	procs.h (SCM_CLOSCAR), unif.h (SCM_ARRAY_NDIM, SCM_ARRAY_CONTP),
+	variable.h (SCM_VARIABLEP):  Replace SCM_UNPACK_CAR
+	appropriately.
+
+2000-05-23  Dirk Herrmann  <D.Herrmann@tu-bs.de>
+
+	* gc.c (free_list_length), hash.c (scm_hasher), macros.c
+	(scm_macro_type), objects.c (scm_class_of), options.c
+	(scm_options), print.c (scm_iprin1), strports.c (st_seek), throw.c
+	(SCM_LAZY_CATCH_P):  Replace SCM_UNPACK_CAR appropriately.
+
+2000-05-23  Dirk Herrmann  <D.Herrmann@tu-bs.de>
+
+	* eval.c (scm_macroexp, SCM_CEVAL, scm_force), tags.h:  Replace
+	SCM_UNPACK_CAR with SCM_CELL_TYPE or SCM_CELL_WORD_0.
+
+	* eval.c (scm_force):  Add documentation.
+
+	* eval.c (scm_force, scm_cons_source):  Don't access cells via
+	SCM_{SET}?C[AD]R unless they are known to be cons cells.
+
+2000-05-23  Dirk Herrmann  <D.Herrmann@tu-bs.de>
+
+	* strings.h (SCM_NSTRINGP, SCM_NRWSTRINGP), tags.h
+	(SCM_NDOUBLE_CELLP), vectors.h (SCM_NVECTORP):  Deprecated.
+
+	* gc.c (scm_igc), gc.h (SCM_PTR_MASK, SCM_PTR_LT):  Removed #ifdef
+	nosve #endif conditionally compiled code.
+
+2000-05-23  Michael Livshin  <mlivshin@bigfoot.com>
+
+	* gc.c (scm_heap_seg_data_t): fixed comment for the `span' member.
+
+2000-05-22  Michael Livshin  <mlivshin@bigfoot.com>
+
+	* guile-doc-snarf.in: put the preprocessed file through sed to
+	trim all lines to 1024 chars.  I hope it doesn't break anybody's
+	sed.  we'll see.  (note: this is lossy trimming, i.e. the spill
+	isn't wrapped around but actually chopped off.  this seemed to me
+	safe because the current snarfer doesn't understand multi-line
+	cookies anyway.  in the long term, it would be nice not to depend
+	on AWK for anything.)
+
+	* gc.h (SCM_[SET_]CELL_{WORD,OBJECT}, SCM_VALIDATE_CELL): reverted
+	the previous change to this macros, after deciding to torture the
+	snarfer instead.
+
+2000-05-21  Michael Livshin  <mlivshin@bigfoot.com>
+
+	* gc.h (SCM_[SET_]CELL_{WORD,OBJECT}, SCM_VALIDATE_CELL): brought
+ 	the yucky, ugly and nasty conditional compilation back.  sorry,
+ 	but it was either that or requiring GAWK to build Guile.
+	(lots of places): removed the code that implemented the old GC
+ 	scheme.
+
+	* init.c (scm_boot_guile_1): removed the code conditioned on
+ 	!GUILE_NEW_GC_SCHEME.
+
+	* __scm.h: (GUILE_NEW_GC_SCHEME): removed.
+
+	* gc.c (scm_protect_object, scm_unprotect_object): change the
+ 	implementation to more efficient (at least in the time complexity
+ 	sense).  the calls should now also be thread-safe -- I suspect
+ 	that people expect them to be.  (thanks to Han-Wen Nienhuys)
+	(lots of places): removed the code that implemented the old GC
+ 	scheme.
+
+	* hashtab.c (scm_hash_fn_create_handle_x): add missing
+	SCM_REALLOW_INTS before return.  I really wonder about the
+	possible interactions between hashtables, threads & GC.  it
+	doesn't look healthy at all.
+
+2000-05-20  Dirk Herrmann  <D.Herrmann@tu-bs.de>
+
+	* unif.c (scm_bit_count):  Fixed the parameter checks.  Thanks to
+	Dale P. Smith.
+
+2000-05-19  Dirk Herrmann  <D.Herrmann@tu-bs.de>
+
+	* __scm.h (SCM_DEBUG_CELL_ACCESSES), gc.h (SCM_):  Added as a new
+	debug option to verify all accesses to cells actually access
+	objects on the heap.
+
+	* gc.h (SCM_VALIDATE_CELL):  Added.  Only performs validation if

+
+	* __scm.h (SCM_DEBUG_REST_ARGUMENT):  Renamed from

+	* dynl.c (DYNL_GLOBAL, sysdep_dynl_link, kw_global, sym_global,
+	scm_dynamic_link, scm_init_dynamic_linking), dynl.h
+	(scm_dynamic_link):  Removed possibility to pass flags to
+	scm_dynamic_link, as it had no effect anyway.
+
+	* filesys.c (scm_fcntl):  Made single optional rest argument into
+	a standard optional argument.
+
+	* hooks.c (scm_run_hook):  A list of rest arguments is never
+	SCM_UNBNDP.
+
+	* list.c (scm_append, scm_append_x), stacks.c (scm_make_stack),
+	strings.c (scm_string_append):	Don't perform half-hearted checks

+	scm_enclose_array, scm_array_in_bounds_p):  Make first mandatory
+	rest argument into a standard mandatory argument.
+
+2000-05-17  Dirk Herrmann  <D.Herrmann@tu-bs.de>
+
+	* __scm.h:  Added SCM_DEBUG as default debug option. (Thanks to
+	Keisuke Nishida for the suggestion.)  Added debug option
+	SCM_DEBUG_REST_ARGUMENTS.
+
+	* eval.c (scm_map, scm_for_each):  Make sure all lists have the

+
+	* numbers.c (scm_logcount, scm_integer_length):  Reordered

+	SCM_OUTPUT_PORT_P, SCM_CHARP, respectively.
+
+2000-05-14  Gary Houston  <ghouston@arglist.com>
+
+	* stime.c (scm_strftime): if HAVE_TM_ZONE is not defined, hack the
+	TZ environment variable so that the %Z format returns the zone
+	from the input vector instead of the system default.
+
+	from Keisuke Nishida:
+	* fports.c (scm_setvbuf): minor docstring fix.
+	* ports.h (scm_generic_fgets): obsolete prototype deleted.
+
+2000-05-11  Dirk Herrmann  <D.Herrmann@tu-bs.de>

+	help developers to get rid of references to deprecated code.
+
+	* numbers.[ch] (SCM_POSFIXABLE, SCM_NEGFIXABLE, SCM_UNEGFIXABLE,

+
+2000-05-10  Dirk Herrmann  <D.Herrmann@tu-bs.de>
+
+	* gc.h (scm_cell, SCM_CELL_WORD, SCM_CELL_OBJECT,
+	SCM_SET_CELL_WORD, SCM_SET_CELL_OBJECT):  Scheme cells now consist

+
+2000-05-10  Dirk Herrmann  <D.Herrmann@tu-bs.de>
+
+	* numbers.c:  No need to include unif.h.
+
+	(IS_INF):  Returned to old test for now:  x == x + 1 will not work

+
+2000-05-09  Dirk Herrmann  <D.Herrmann@tu-bs.de>

+
+	(scm_number_to_string, scm_sum, scm_difference, scm_two_doubles,
+	scm_num2long, scm_num2long_long, scm_num2ulong):  Reordered

+
+2000-05-09  Marius Vollmer  <mvo@zagadka.ping.de>
+
+	* scmsigs.c (take_signal): Execute SCM_ASYNC_TICK for SIGSEGV,

+
+	(scm_loc_features, features, scm_add_feature, scm_init_feature):
+	Removed variable 'scm_loc_features' as a pointer to the SCM value
+	holding the features list.  Using variable 'features' instead,
+	which holds the interned pair.  Thus, SCM_SETCDR can be used
+	instead of pointer trickery.
+
+2000-05-08  Dirk Herrmann  <D.Herrmann@tu-bs.de>
+
+	* alist.c (scm_acons):  Use SCM{_SET}?_CELL_OBJECT as long as a

+
+2000-05-08  Dirk Herrmann  <D.Herrmann@tu-bs.de>
+
+	* eval.c (ASRTSYNTAX, scm_m_body, scm_m_letrec1):  Removed
+	ASRTSYNTAX.  Using SCM_ASSYNT instead.

+
+2000-05-05  Dirk Herrmann  <D.Herrmann@tu-bs.de>

+
+2000-05-05  Dirk Herrmann  <D.Herrmann@tu-bs.de>

+	(scm_make_weak_key_hash_table, scm_make_weak_value_hash_table,
+	scm_make_doubly_weak_hash_table):  Fixed critical sections.

+
+2000-05-05  Dirk Herrmann  <D.Herrmann@tu-bs.de>
+

+	Fixed some goto-related initialization bugs (introduced by me).
+
+2000-05-04  Dirk Herrmann  <D.Herrmann@tu-bs.de>
+
+	* numbers.h (SCM_INUM0):  Uses SCM_MAKINUM instead of SCM_PACK.
+
+	* dynl.c (dynl_obj, DYNL_OBJ, get_dynl_obj):  Removed.
+
+	(DYNL_FILENAME, DYNL_HANDLE):  Use SCM_CELL... macros instead of

+
+	(SET_DYNL_HANDLE):  Added.
+
+	(scm_dynamic_object_p):  Simplified.

+	Eliminated call to get_dynl_obj.
+
+2000-05-03  Marius Vollmer  <mvo@zagadka.ping.de>
+
+	* scmsigs.c (orig_handlers) [!HAVE_SIGACTION]: Fix declaration to
+	be an array of function pointers instead of being a pointer to an
+	array returning function.  Thanks to Kalle Olavi Niemitalo!
+
+2000-05-03  Dirk Herrmann  <D.Herrmann@tu-bs.de>
+
+	* numbers.c (scm_divbigbig, scm_divbigint), numbers.h
+	(scm_divbigbig, scm_divbigint):  Don't return zero any more to
+	indicate that a division has a remainder, return SCM_UNDEFINED
+	instead.  It is improbable that anyone actually used these
+	functions outside of numbers.c.  For this reason and due to the
+	change in behaviour the functions are static now.  Thus, if
+	surprisingly there are users of	these functions they will at least
+	get alarmed.
+
+	* numbers.c:  Removed #ifdef SCM_BIGDIG #endif in those functions,
+	that already have a clean dispatch order.  Note: SCM_BIGDIG is
+	always defined.
+
+	* numbers.c (scm_inexact_p):  Simplified.
+
+	* numbers.c (scm_num_eq_p, scm_less_p, scm_max, scm_min,
+	scm_product, scm_num2dbl, scm_angle):  Reordered dispatch
+	sequence, thereby fixing some comparisons of SCM values with
+	integer constants.
+
+	* numbers.c (scm_divide):  Division by zero of inums leads to an
+	error now.  (Formerly, an infinite number was returned.)
+
+	Respect the fact, that scm_divbigbig does now return SCM_UNDEFINED
+	if a division has a remainder.
+
+2000-05-02  Gary Houston  <ghouston@arglist.com>
+
+	* Makefile.am (INCLUDES): add ${INCLTDL} (thanks to Tim Mooney).

+	to be zero.
+
+2000-05-01  Gary Houston  <ghouston@arglist.com>
+
+	* scmsigs.c: fix the definition of orig_handlers for the case

+	libguile.h: moved to top level directory.
+
+2000-04-28  Dirk Herrmann  <D.Herrmann@tu-bs.de>
+
+	* numbers.c (SCM_SWAP):  Moved to the top of the file to allow for
+	a wider use.
+
+	* numbers.c (scm_modulo, scm_gcd, scm_lcm, scm_logand, scm_logior,
+	scm_logxor):  Reordered dispatch sequence, thereby fixing some
+	comparisons of SCM values with integer constants.
+
+	* number.c (scm_logtest):  Removed some redundant SCM_{N}?IMP
+	tests.
+
+2000-04-28  Dirk Herrmann  <D.Herrmann@tu-bs.de>
+
+	* numbers.c (scm_quotient, scm_remainder):  Removed code that was
+	conditionally compiled based on BADIVSGNS.  BADIVSGNS does not
+	occur anywhere else throughout guile.
+
+	* numbers.c (scm_quotient):  Fixed parameter number in error
+	message.
+
+	* numbers.c (scm_remainder):  Reordered dispatch sequence.
+

+
+	* procs.c (scm_init_iprocs), procs.h (scm_subr, scm_iproc,
+	scm_dsubr, scm_init_iprocs):  Removed.
+
+	* procs.h (SCM_SUBRF, SCM_DSUBRF):  Access the cell words
+	directly instead of casting a cell to a C struct.
+
+2000-04-22  Mikael Djurfeldt  <mdj@thalamus.nada.kth.se>
+
+	Better modularization of GC extensions through new C level GC
+	hooks:

+	the root build directory.
+
+	* numbers.c (scm_odd_p, scm_even_p): Use SCM_WRONG_TYPE_ARG
+	instead of SCM_ASSERT (0, ...).  (Some compilers will complain

+
+	* debug.c (scm_make_memoized), dynl.c (scm_dynamic_link):  Smob

+	unpacked/packed.
+
+	* ports.h (SCM_SETPTAB_ENTRY, SCM_SETSTREAM):  Cast input to
+	scm_bits_t.
+
+2000-03-31  Mikael Djurfeldt  <mdj@thalamus.nada.kth.se>

+	binary compatibility---let's remove it next time we alter some
+	major structure.
+
+	* coop.c (coop_quitting_p, coop_cond_create, coop_mutex_create,
+	coop_mother, coop_child): New variables.
+	(mother): New function.
+	(coop_create): New thread spawning mechanism which uses a "mother
+	thread".  The "dummy" pthreads aren't healthy enough to give birth
+	to new threads since Linux threads thinks they are asleep.
+
+	* coop-defs.h (struct coop_t): Removed dummy_mutex.
+
+	* coop-defs.h, coop-threads.c (struct coop_t): Eliminate
+	`sto'-field when GUILE_PTHREAD_COMPAT is enabled.
+
+2000-03-30  Dirk Herrmann  <D.Herrmann@tu-bs.de>
+
+	* arbiters.c (scm_make_arbiter), async.c (scm_async), dynwind.c

+	SCM value is equal to #t or #f.
+
+	* eq.c (scm_eqv_p, scm_equal_p):  Don't use SCM_CAR to access the

+
+	* coop.c (coop_create): Set `specific' field, not `data' to NULL.
+
+2000-03-29  Dirk Herrmann  <D.Herrmann@tu-bs.de>
+
+	* smob.h (SCM_NEWSMOB, SCM_NEWSMOB2, SCM_NEWSMOB3, SCM_SMOB_DATA,
+	SCM_SET_SMOB_DATA, SCM_TC2SMOBNUM, SCM_SMOBNUM):  To access smob
+	data, use SCM_{SET_}?CELL_TYPE or SCM_{SET_}?WORD_[1-3].
+
+	Note that this implies that smob data has always to be passed as
+	values of type scm_bits_t.
+
+2000-03-29  Mikael Djurfeldt  <mdj@thalamus.nada.kth.se>
+
+	* threads.c (scm_init_threads): Pass 0 size to scm_make_smob_type
+	for scm_tc16_thread.  As the current COOP threads are written, GC
+	is not supposed to manage storage for threads.
+
+	* error.c (scm_error): Don't try to throw an error if
+	scm_gc_heap_lock is true.
+
+	* coop.c (coop_finish): New function.  Called at exit.
+	(coop_aborthelp): Free thread structures when threads die.

+
+2000-03-29  Dirk Herrmann  <D.Herrmann@tu-bs.de>

+
+2000-03-28  Dirk Herrmann  <D.Herrmann@tu-bs.de>
+
+	* symbols.h (SCM_LENGTH, SCM_SETLENGTH):  Access the length field

+
+2000-03-27  Dirk Herrmann  <D.Herrmann@tu-bs.de>
+
+	* gc.h (SCM_NEWCELL, SCM_NEWCELL2):  Use SCM_SET_CELL_TYPE to set
+	the type entry of a new cell.  Added a comment about things to
+	remember when updating the list of free cells.
+
+	(SCM_FREEP, SCM_MARKEDP):  Use SCM_CELL_TYPE to access the type
+	entry of a cell.
+
+2000-03-27  Dirk Herrmann  <D.Herrmann@tu-bs.de>
+
+	* pairs.h (SCM_CAR, SCM_CDR, SCM_SETCAR, SCM_SETCDR):  Use
+	SCM_CELL_OBJECT and SCM_SET_CELL_OBJECT.  This change implies that
+	with strict type checking enabled these macros will only work if
+	given valid SCM parameters.
+
+	(SCM_GCCDR):  Moved to tags.h.
+
+	* tags.h (SCM_GCCDR):  Moved here from pairs.h.
+
+2000-03-26  Dirk Herrmann  <D.Herrmann@tu-bs.de>
+
+	* tags.h (SCM2PTR, PTR2SCM):  Moved to gc.h.
+
+	* pairs.h (scm_cell, SCM_CELLPTR, SCM_CELL_WORD*, SCM_CELL_OBJECT*,
+	SCM_SET_CELL_WORD*, SCM_SET_CELL_OBJECT*, SCM_CELL_TYPE,
+	SCM_SET_CELL_TYPE, SCM_PTR_LT, SCM_PTR_MASK, SCM_PTR_GT,
+	SCM_PTR_LE, SCM_PTR_GE, SCM_CELL_WORD_LOC, SCM_NEWCELL,

+
+	(SCM_CARLOC, SCM_CDRLOC, SCM_SETAND_CAR, SCM_SETAND_CDR,
+	SCM_SETOR_CAR, SCM_SETOR_CDR):  Moved to gc.h.  These names should
+	be changed, though, since the macros are not only pair related.
+
+	(SCMPTR):  Deleted.
+
+	* gc.h (SCM2PTR, PTR2SCM, scm_cell, SCM_CELLPTR, SCM_CELL_WORD*,
+	SCM_CELL_OBJECT*, SCM_SET_CELL_WORD*, SCM_SET_CELL_OBJECT*,
+	SCM_CELL_TYPE, SCM_SET_CELL_TYPE, SCM_PTR_LT, SCM_PTR_MASK,

+
+2000-03-25  Dirk Herrmann  <D.Herrmann@tu-bs.de>
+
+	* tags.h (SCM_STRICT_TYPING):  New macro that, if defined,

+	(SCM_EQ_P):  Defined as a macro equivalent for eq?.
+
+2000-03-25  Dirk Herrmann  <D.Herrmann@tu-bs.de>
+
+	* tags.h (SCM_POINTERS_MUNGED):  Removed.
+
+	* gc.c (scm_gc_sweep, init_heap_seg):  Removed use of
+	SCM_POINTERS_MUNGED, thus fixing some illegal casts to SCM.
+
+2000-03-24  Dirk Herrmann  <D.Herrmann@tu-bs.de>
+
+	* pairs.h (SCM_CELL_OBJECT, SCM_CELL_OBJECT_[0-3],
+	SCM_SET_CELL_OBJECT, SCM_SET_CELL_OBJECT_[0-3], SCM_CELL_TYPE,
+	SCM_SET_CELL_TYPE):  Added a set of low level macros for accessing
+	cell entries.
+	(SCM_CELL_WORD_[0-3]): Renamed from the SCM_CELL_WORD[0-3].
+
+	* procs.h, procs.c:  Instead of SCM_{SET_}?CELL_WORD[12], use the
+	newly introduced SCM_{SET_}?CELL_OBJECT_[12] macros.
+
+2000-03-23  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
+
+	* tags.h: Disabled definition of SCM_VOIDP_TEST.
+
+	Defining SCM as void * introduces problems which haven't been
+	handled yet.  Developers who work with these issues can enable it
+	in their working copies.
+
+	Disabling this definition exposes a set of newly introduced and
+	older misuses of types which causes warning messages during
+	compilation.  We'll fix this successively.
+
+	* gc.c (scm_mark_locations): Changed * (SCM **) X --> * (SCM *) X
+	in order to obtain a value of type SCM.
+	(scm_cellp): Updated with new changes to scm_mark_locations.
+
+	* continuations.h (SCM_SETJMPBUF): Cast second arg into SCM.
+
+	* continuations.c (scm_make_cont): Removed cast of size_t into
+	long.
+
+	* symbols.h (SCM_SETCHARS): Cast second arg into SCM.
+
+2000-03-22  Dirk Herrmann  <D.Herrmann@tu-bs.de>
+
+	* numbers.h (SCM_SETNUMDIGS):  Use SCM_BIGSIZEFIELD macro for
+	shifting, not constant.  Thanks to Dale P. Smith.
+
+	* numbers.c (scm_sum, scm_difference):  Don't test a SCM value
+	for being less than zero.  Decode it to a C value first.  Again,
+	thank you Dale.
+
+2000-03-22  Dirk Herrmann  <D.Herrmann@tu-bs.de>
+
+	* numbers.h, ramap.c, struct.h, vectors.h:  Don't use SCM2PTR for
+	non scheme values.  If raw data is stored in SCM variables, it has
+	to be accessed using SCM_UNPACK until a better solution is found.
+
+2000-03-22  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
+
+	* tags.h (SCM_ECONSP, SCM_NECONSP): More corrections of
+	pointer-arithmetic induced by the SCM_PACK/UNPACK change.
+
+	* print.c (scm_iprin1): SCM_PACK/UNPACK corrections.
+
+	* gc.c (scm_gc_sweep): SCM_PACK/UNPACK corrections.
+
+	* eval.c (SCM_CEVAL, scm_unmemocar): SCM_PACK/UNPACK corrections.
+
+	* dynwind.c (scm_swap_bindings): SCM_PACK/UNPACK corrections.
+
+	* async.c, __scm.h: Removed lots of the old async click logic.  It
+	is possible to reinsert it by defining GUILE_OLD_ASYNC_CLICK in
+	__scm.h.  Let's try this out and dump the old code after the
+	threads reorganization.
+	(set-tick-rate, set-switch-rate): Conditionally removed.
+
+2000-03-21  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
+
+	* gc.c (scm_gc_mark): Bugfix 1: The recent SCM_PACK/UNPACK change
+	made SCM values into pointers.  This turned an arithmetic
+	computation of the address of the vcell into a pointer-arithmetic
+	one, thereby screwing up marking of structs.
+	Bugfix 2: Removed incompletely introduced loop variable `j' used
+	when protecting the tail array of a struct.
+
+2000-03-21  Dirk Herrmann  <D.Herrmann@tu-bs.de>
+
+	* struct.h (SCM_STRUCT_DATA):  Don't cast SCM values to pointers.
+
+2000-03-21  Dirk Herrmann  <D.Herrmann@tu-bs.de>
+
+	* symbols.h, symbols.c (scm_strhash):  Declare the string
+	parameter as constant, since it is not modified.
+
+	* symbols.c (scm_intern_obarray_soft,
+	scm_sysintern0_no_module_lookup):  Can now pass constant strings
+	to scm_strhash without need for casting.
+
+2000-03-21  Dirk Herrmann  <D.Herrmann@tu-bs.de>
+
+	* vectors.h (SCM_VELTS, SCM_VELTS_AS_STACKITEMS):  Don't cast SCM
+	values to pointers.  Use SCM2PTR instead.
+
+2000-03-21  Dirk Herrmann  <D.Herrmann@tu-bs.de>
+
+	* async.c (scm_set_tick_rate, scm_set_switch_rate):  Don't unpack
+	results of SCM_INUM.
+
+2000-03-21  Mikael Djurfeldt  <mdj@thalamus.nada.kth.se>
+
+	* init.c (scm_boot_guile_1): Renamed GUILE_GC_TRIGGER_1 -->
+	GUILE_MIN_YIELD_1, GUILE_GC_TRIGGER_2 --> GUILE_MIN_YIELD_2.
+	GUILE_MIN_YIELD_X now take *positive* fractions of heap size.
+
+	* gc.c, gc.h (SCM_MIN_YIELD_1, SCM_MIN_YIELD_2,
+	min_yield_fraction, min_yield, adjust_min_yield): Renamed from
+	SCM_GC_TRIGGER_1, SCM_GC_TRIGGER_2, gc_trigger_fraction,
+	gc_trigger, adjust_gc_trigger.
+
+	* gc.c (alloc_some_heap): Further improvement of minimal heap size
+	prediction.
+	(SCM_MAX): New macro.
+	(scm_freelist_t): New field: collected_1. Previous amount of
+	collected cells.
+	(gc_sweep_freelist_finish): Trigger based on two last values of
+	freelist->collected to avoid unnecessary allocation due to
+	temporary peaks.
+	(SCM_INIT_HEAP_SIZE_1, SCM_GC_TRIGGER_1, SCM_GC_TRIGGER_2):
+	Adjusted to 45000 cells, 40% and 40%.  Gives quick startup
+	without extra heap allocation.
+
+2000-03-20  Dirk Herrmann  <D.Herrmann@tu-bs.de>
+
+	* numbers.h (SCM_MAKINUM):  The parameter to SCM_MAKINUM should
+	already be a C value.  No need to unpack it.
+
+	* numbers.c (scm_long_long2num):  Cast the parameter to scm_bits_t
+	if we know it fits into an inum.
+
+	* ramap.c (ramap_rp):  An scm_tc7_[ui]vect object does point to a
+	field of long values.  In contrast, SCM_VELTS accesses a field of
+	SCM values.
+
+2000-03-20  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
+
+	* gc.c (scm_gc_stats): Inserted explanation of local_scm_mtrigger
+	etc.
+	(scm_gc_yield_1): New variable: Holds previous yield.  Used to
+	make better judgements.
+	(gc_sweep_freelist_finish): Inserted explanation of use of
+	gc_trigger.
+
+	* print.h, stacks.h, options.c, options.h: Changed C++
+	commentaries to C.
+
+2000-03-20  Dirk Herrmann  <D.Herrmann@tu-bs.de>
+
+	* tags.h (SCM2PTR, PTR2SCM):  Use SCM_PACK / SCM_UNPACK correctly.
+
+	* numbers.h (SCM_INUMP, SCM_MAKINUM, SCM_INUM0, SCM_COMPLEX_REAL,
+	SCM_COMPLEX_IMAG, SCM_NUMP, SCM_BDIGITS):  Use SCM_PACK /
+	SCM_UNPACK / SCM2PTR correctly.
+
+2000-03-20  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
+
+	* gc.c (adjust_gc_trigger): Improved documentation.
+	(alloc_some_heap): Since gc_trigger is used against
+	freelist->collected, this is the value which should be used to
+	predict minimum growth.
+
+2000-03-20  Dirk Herrmann  <D.Herrmann@tu-bs.de>
+
+	* eval.h:  Fix mixup of packed/unpacked SCM values.  (Thanks
+	Thien-Thi Nguyen for the patch.)
+
+2000-03-20  Dirk Herrmann  <D.Herrmann@tu-bs.de>
+
+	* numbers.c (scm_ash):  Fixed typing problems with the second
+	parameter and added some documentation.  (Thanks Thien-Thi Nguyen
+	for indicating the problem.)
+
+2000-03-19  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
+
+	* gc.c, gc.h (scm_gc_yield): New variable.
+	(adjust_gc_trigger): Use scm_gc_yield.
+	(alloc_some_heap): Use scm_gc_yield instead of
+	scm_gc_cells_collected.
+
+	* coop-threads.c: Addd #include "root.h", #include "strings.h".

+	trigger adjustmeant: Take yield (freed cells) for all freelists
+	into account.

+	to 50000 cell heap with 45% trigger.
+	(scm_gc_cells_collected): Reintroduced.
+	(SCM_HEAP_SIZE): New macro.
+	(scm_gc_sweep): Reintroduced correct computation of
+	scm_cells_allocated.
+	(scm_freelist_t): Corrected commentary for field `cluster_size':
+	Clustersize counts objects, not cells;  New member
+	`clusters_allocated'.
+
+2000-03-19  Michael Livshin  <mlivshin@bigfoot.com>
+
+	* *.[hc]: add Emacs magic at the end of file, to ensure GNU
+ 	indentation style.
+
+2000-03-19  Mikael Djurfeldt  <mdj@thalamus.nada.kth.se>
+
+	* threads.h: Added #include "libguile/throw.h".  (Thanks to
+	Thien-Thi Nguyen.)

+
+	* tags.h: (SCM_DOUBLE_CELLP, SCM_NDOUBLE_CELLP): new macros (bad
+	names, anyone got any better ones?)
+
+	* gc.h: (typedef struct scm_freelist_t) remove from here.

+ 	parameter (the span).
+	(CLUSTER_SIZE_IN_BYTES, ALIGNMENT_SLACK) new macros.
+	(typedef struct scm_freelist_t) moved here from gc.h, it had no
+ 	business being externally visible.
+	(typedef struct scm_heap_seg_data_t) renamed from
+ 	scm_heap_seg_data, to be style-compliant.
+	(scm_mark_locations) if the possible pointer points to a
+ 	double-cell, check that it's properly aligned.
+	(init_heap_seg) align double-cells properly, work with the
+ 	assumption that the segment size divides cleanly by cluster size.
+	(round_to_cluster_size) new function.
+	(alloc_some_heap, make_initial_segment) use round_to_cluster_size
+ 	to satisfy the new init_heap_seg invariant.

+	* gc.c, gc.h: Cleanup of the change of 2000-03-15.
+	Cluster sizes are now independent of GC trigger values.
+	GUILE_GC_TRIGGER_n can now specify a relative trigger value:
+	A negative integer gives fraction of total heap size in percent.
+	(SCM_GC_TRIGGER_1, SCM_GC_TRIGGER_2): Default values set to -40.
+
+	* init.c (scm_boot_guile_1): Introduced new variable
+	GUILE_MAX_SEGMENT_SIZE; New environment variable names:
+	GUILE_INIT_SEGMENT_SIZE_1, GUILE_GC_TRIGGER_1,
+	GUILE_INIT_SEGMENT_SIZE_2, GUILE_GC_TRIGGER_2
+
+2000-03-16  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
+
+	* __scm.h (GC_FREE_SEGMENTS): Disable this until we have made
+	freeing of segment work with the new GC scheme.  (Thanks to
+	Michael Livshin.)  Oops, also happened to make GUILE_NEW_GC_SCHEME
+	the default, but I'll let this change stay in CVS Guile since this
+	code is not expected to contain serious bugs.
+
+2000-03-16  Mikael Djurfeldt  <mdj@thalamus.nada.kth.se>
+
+	* gc.c, gc.h (scm_map_free_list): Define also if GUILE_DEBUG is
+	defined.
+	(scm_free_list_length): New procedure (GUILE_DEBUG).
+	Fixed a small but serious bug introduced by the previous change.
+
+	* gc.c (scm_gc_sweep): Moved variable n_objects to inner sweep
+	loop and declare as register.
+
+	* gc.c (scm_gc_sweep): Sigh... forgot to clear private freelists
+	after GC.
+
+Wed Mar 15 08:27:04 2000  Greg J. Badros  <gjb@cs.washington.edu>
+
+	* fluids.c: Docstring patch from Keisuke Nishida.  Some
+	reindentation, too, and a couple formals renamed.  Should
+	fluid-set! return UNSPECIFIED instead of a value?
+
+Wed Mar 15 08:24:58 2000  Greg J. Badros  <gjb@cs.washington.edu>
+
+	* Makefile.am: Separate out DOT_X_FILES and DOT_DOC_FILES, and
+	generate the latter from the concrete listing of the former.  Then
+	make guile-procedures.txt depend on DOT_DOC_FILES instead of
+	*.doc, so that rebuilding it works.
+
+Wed Mar 15 08:12:14 2000  Greg J. Badros  <gjb@cs.washington.edu>
+
+	* libguile.h: Include libguile/validate.h.  Thanks Keisuke Nishida!
+
+	* guile-snarf.awk.in: Replace docstring line-ending \n" and \n\n"
+	with nothing and \n, respectively. Thanks Keisuke Nishida for
+	noticing this problem.
+
+2000-03-15  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
+
+	* __scm.h (GUILE_NEW_GC_SCHEME): Define this if you want to test a
+	new way of allocating heap.  It makes Guile fast, but still
+	contains bugs.
+
+	* gc.c, gc.h, pairs.h, init.c: Implementation of a new way of
+	allocating heap.  The basic idea is to trigger GC every Nth
+	allocated cell and grow heap when free list runs out.  The scheme
+	has been extended so that GC isn't triggered until all remaining
+	cells are used.  The implementation is also prepared for
+	development in the direction of POSIX threads.
+
+	* gc.c (SCM_EXPHEAP): In order to grow by a factor of 1.5,
+	SCM_EXPHEAP should return half of the heap size.
+
+2000-03-14  Mikael Djurfeldt  <mdj@thalamus.nada.kth.se>
+
+	The following change to init.c is only enabled if Guile was
+	configured with --enable-guile-debug.
+
+	* init.c (scm_i_getenv_int): New function.
+	(scm_boot_guile_1): Use the environment variables
+	GUILE_INIT_HEAP_SIZE, GUILE_INIT_HEAP_SIZE2 to select heap size if
+	they exist.  (This may be replaced by a Scheme level mechanism in
+	the future.)
+
+	* objprop.c (s_scm_set_object_property_x): Use scm_assq instead of
+	scm_assoc.  (Thanks to Keisuke Nishida.)
+
+2000-03-14  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
+
+	* eval.c, lang.c, lang.h (scm_lisp_nil, scm_lisp_t): Renamed from
+	scm_nil, scm_t.  (Thanks to Keisuke Nishida.)
+
+2000-03-14  Mikael Djurfeldt  <mdj@thalamus.nada.kth.se>
+
+	* init.c (scm_boot_guile_1): Use same initial segment size for
+	1-word and 2-word segments.  Having the smaller size causes Guile
+	to GC too often.  Obviously something needs to be done to allow
+	for a smaller 2-word segment without this to happen.  (The amount
+	of heap for each type should be automatically adapted to the
+	application somehow.)
+
+	[Almost all of these changes should be documented in the NEWS
+	file.]
+
+	* gc.h (scm_freelist_t): New type.
+
+	* pairs.h (SCM_NEWCELL, SCM_NEWCELL2): Use new style freelists.
+
+	* gc.c (SCM_INIT_HEAP_SIZE): Changed from 32768 --> 40000 so that
+	all of Guile basics fits into one segment and there suitable room
+	for work.
+	(SCM_EXPHEAP): Now takes an argument.  Grow by a factor of 1.5
+	instead of 2.
+	(scm_freelist, scm_freelist2): Now of type scm_freelist_t.
+	Freelists now contains information about object span, cells
+	collected and amount of cells in heap segments belonging to the
+	list.
+	(scm_heap_size, scm_gc_cells_collected): Removed.
+
+	* init.c (scm_boot_guile_1): Make 2-word segment 8K (512 cells).
+
+	* Makefile.am (libguile_la_LDFLAGS): Bumped library version
+	number.
+
+	* __scm.h eq.c, eval.c, gc.c, gc.h, gh_data, hash.c, numbers.c,
+	numbers.h, objects.c, ramap.c, random.c, unif.c, unif.h: Extensive
+	rewrite of handling of real and complex numbers.
+	(SCM_FLOATS, SCM_SINGLES): These #ifdef conditionals have been
+	removed along with the support for floats.  (Float vectors are
+	still supported.)
+
+	* tags.h (scm_tcs_bignums): Removed.
+	(scm_tc16_bigpos, scm_tc16_bigneg): Replaced by scm_tc16_big.
+	Use SCM_BIGSIGN(x) to test for sign!
+	(scm_tc16_big): The new bignum type.
+	(SCM_REAL_PART, SCM_IMAG_PART): Removed.
+
+	* numbers.h (SCM_BIGSIGN): Sign moved to bit 16.
+	(scm_makdbl): Deprecated.
+	(SCM_NEWREAL, SCM_NEWCOMPLEX): New macros.
+	(SCM_SINGP): Deprecated.
+	(SCM_FLO): Removed.
+	(SCM_INEXP, SCM_CPLXP): Deprecated.
+	(SCM_INEXACTP, SCM_COMPLEXP): New macros.
+	(SCM_COMPLEX_REAL, SCM_COMPLEX_IMAG): Renamed from
+	SCM_REAL, SCM_IMAG (and now only valid for complex numbers).
+	(SCM_REAL, SCM_IMAG): New, *deprecated*, selectors which work both
+	for doubles and complex numbers.
+	(SCM_REAL_VALUE): New selector for doubles.
+	(scm_double_t, scm_complex_t): New types.
+	(scm_dbl): Removed.
+
+	* numbers.c (scm_floprint, scm_floequal): Removed.
+	(scm_print_real, scm_print_complex, scm_real_equalp,
+	scm_complex_equalp): New functions.
+
+	* unif.c (scm_makflo): Removed.
+
+	* smob.h (SCM_SMOB_PREDICATE): New macro.
+	(SCM_NEWSMOB2, SCM_RETURN_NEWSMOB2, SCM_NEWSMOB3,
+	SCM_RETURN_NEWSMOB3): New macros.
+
+1999-11-21  Michael Livshin  <mlivshin@bigfoot.com>
+
+	The following changes implement primitive support for double cells
+	(i.e. four-word cells) and change the representation of some
+	things to multi-cells instead of cons+malloc.  (Applied and
+	modified by mdj.)
+
+	* pairs.h (SCM_NEWCELL2): double-cell variants of SCM_NEWCELL.
+	(SCM_CELL_WORD, SCM_CELL_WORDLOC, SCM_SET_CELL_WORD): primitive
+	multi-cell access macros (used by the ones below).
+	(SCM_CELL_WORD[0-3], SCM_SET_CELL_WORD[0-3]): multi-cell access
+ 	macros.
+
+	* gc.c (scm_freelist2): multi-cell freelists.
+	(inner_map_free_list): map_free_list, parameterized on ncells.
+  	"nn cells in segment mm" was misleading for ncells > 1; changed to
+ 	"objects".  still print cells too, though.
+	(scm_map_free_list): rewritten using inner_map_free_list.
+	(scm_check_freelist): get freelist as parameter, since now we have
+ 	more than one.
+	(scm_debug_newcell2): multi-cell variants of
+ 	scm_debug_newcell.
+	(scm_gc_for_newcell): take ncells and freelist pointer as
+ 	parameters.
+	(scm_gc_mark): add case for tc7_pws (procedures with setters are
+ 	now double cells).
+	(scm_gc_sweep): don't free the float data, since it's not malloced
+ 	anymore.
+	(init_heap_seg): didn't understand what n_new_objects stood for,
+ 	so changed to n_new_cells.
+	(make_initial_segment): new function, makes an initial segment
+ 	according to given ncells.
+	(scm_init_storage): call make_initial_segment, for ncells={1,2,3}.
+
+	* numbers.c (scm_makdbl): no malloc'ing needed, so the
+ 	{DEFER,ALLOW}_INTS thing removed.
+
+	* numbers.h (struct scm_dbl): changed to represent a double cell,
+ 	with the number in the second half.
+
+	* dynwind.c: changed the wind-guards representation to double
+ 	cell.
+
+	* procs.c, procs.h: changed the procedure-with-setter representation
+	to double cell.
+
+	* async.c, async.h: made async representation a double cell.
+
+	* dynl.c: made dynamic_obj representation a double cell.
+
+2000-03-13  Gary Houston  <ghouston@arglist.com>
+
+	* ports.c (flush_void_port): renamed to flush_port_default.
+	(end_input_void_port): renamed to end_input_default.
+
+	* init.c (scm_standard_stream_to_port): create a void port instead
+	of opening /dev/null if the standard file descriptors are bad.
+	advantages: no portability problems, doesn't waste a file descriptor,
+	simplifies the code (thanks to Marius for the idea).
+
+	* vports.c (s_scm_make_soft_port): call scm_port_non_buffer.
+
+	* void ports: make reading from a void port give EOF instead of
+	segv:
+	* ports.c (s_scm_sys_make_void_port): modified docstring.
+	(fill_input_void_port): new proc.
+	(scm_init_ports): set up fill_input_void_port.
+	* ports.c (scm_port_non_buffer): new proc.
+	(scm_void_port): call scm_port_non_buffer.
+
+	* fports.c (scm_setvbuf): docstring: remove the fcntl documentation
+	which was incorrectly appended.
+
+2000-03-13  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
+
+	* guile-doc-snarf.in: Don't use absolute path for `sed'.  (Note
+	that we can't use autoconf for this.  Autoconf itself relies on
+	the existence of `sed' somewhere on your path.)  (Thanks to Dirk
+	Herrman.)
+
+2000-03-13  Mikael Djurfeldt  <mdj@thalamus.nada.kth.se>
+
+	* Makefile.am (libguile_la_SOURCES): Moved iselect.c here from
+	EXTRA_libguile_la_SOURCES.
+
+	* iselect.h: Always declare scm_internal_select.
+
+	* iselect.c (scm_internal_select): Added SCM_ASYNC_TICK at the
+	end.  Also let scm_internal_select be a real function also when
+	not using threads.
+
+	* __scm.h (SCM_TICK): Oops! Forgot to put SCM_ASYNC_TICK here...
+
+2000-03-13  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
+
+	* __scm.h (SCM_ALLOW_INTS, SCM_REALLOW_INTS): Removed call to
+	SCM_ASYNC_TICK.  (This is a preparation for POSIX threads support,
+	and kind of an experiment: Will this cause problems?)
+
+Sun Mar 12 13:26:30 2000  Greg J. Badros  <gjb@cs.washington.edu>
+
+	* Makefile.am: Added *.doc to DISTCLEANFILES.
+
+2000-03-12  Gary Houston  <ghouston@arglist.com>
+
+	* fports.c (scm_fdes_to_port): call fcntl F_GETFL to test that
+	the fdes is valid before doing anything else.  check that
+	the file descriptor supports the modes required.
+	(scm_fport_buffer_add): don't throw an error if fstat doesn't
+	work: just use the default buffer size.
+
+	* throw.c: change an outdated comment about scm_internal_catch
+	BODY: it doesn't take a jumpbuf arg.
+
+	* init.c (scm_standard_stream_to_port): install a handler in case
+	scm_fdes_to_port throws an error.  don't check here whether the
+	file descriptor is valid, since scm_fdes_to_port will do that.
+	set the revealed count depending on whether the port got the
+	standard file descriptor.
+	(stream_body_data): new type.
+	(stream_body, stream_handler): new procs.
+
+2000-03-12  Mikael Djurfeldt  <mdj@thalamus.nada.kth.se>
+
+	* stacks.c, stacks.h, struct.c, tags.h, unif.c (scm_bits_t):
+	Renamed from SCMWORD.
+
+	* tags.h (SCM_NCELLP): Removed (SCMWORD).
+
+	* arbiters.c (SCM_ARB_LOCKED): Use SCM_UNPACK_CAR.
+
+	* async.c, boolean.h, debug.c, dynl.c, dynwind.c, eval.c, eval.h,

+
+	* numbers.h (SCM_SRS, SCM_INUM): Corrected SCM_ASSCM/ASWORD fixes.
+
+	* alist.c, eval.c, net_db.c, posix.c, print.c, snarf.h, struct.c,
+	tags.h: Fixed copyright notices.
+
+	* struct.c, coop-threads.c: SCM_ASSCM/ASWORD fixes.
+
+2000-03-12  Marius Vollmer  <mvo@zagadka.ping.de>
+
+	* init.c (scm_standard_stream_to_port): Check whether the file
+	descriptor is valid and substitute "/dev/null" when not.
+
+2000-03-12  Mikael Djurfeldt  <mdj@thalamus.nada.kth.se>
+
+	* coop-defs.h (struct timespec): Conditionally defined.
+
+	* coop.c (coop_condition_variable_timed_wait_mutex): Use ETIMEDOUT
+	instead of ETIME.
+
+	* readline.c (match_paren): Bugfix: First arg to select is not
+	number of descriptors but the number of the highest descriptor +
+	1.
+
+	This is a preliminary attempt at a cleanup of the threads support
+	code.  It moves things to better places, makes arguments more
+	consistent with the POSIX API (which is used in GNOME's glib), and
+	adds new functionality.
+
+	* readline.c (scm_init_readline): Added new arg to scm_init_mutex.
+
+	* coop-defs.h (scm_mutex_trylock): New macro: alias for
+	coop_mutex_trylock.
+	(scm_cond_init): Changed definition to
+	coop_new_condition_variable_init.
+
+	* coop.c: #include <errno.h>
+	(coop_timeout_qinsert): Moved here from iselect.c
+	(coop_new_mutex_init, coop_new_condition_variable_init): New
+	functions.  The strange names are temporary.  Use scm_mutex_init
+	and scm_cond_init instead.
+	(coop_mutex_trylock): New function.  Uses errno.h:EBUSY.  errno.h
+	is ANSI C, but should we check for individual error codes in
+	configure.in?
+	(coop_condition_variable_timed_wait_mutex): New function.
+	(coop_key_create, coop_setspecific, coop_getspecific,
+	coop_key_delete): New functions.
+
+	* iselect.c (coop_timout_qinsert): Moved to coop.c
+
+2000-03-11  Mikael Djurfeldt  <mdj@thalamus.nada.kth.se>
+

+	SCM_SETOR_CDR): Corrected SCM_ASSCM/WORD fixes.
+
+	* tags.h (SCM_VOIDP_TEST): Renamed from VOIDP_TEST.
+	Layout cleanups.
+
+	* objects.h (SCM_CLASS_FLAGS, SCM_OBJ_CLASS_FLAGS,
+	SCM_SET_CLASS_INSTANCE_SIZE), struct.h (SCM_STRUCT_VTABLE_DATA),
+	proc.h (SCM_CLOSCAR): SCM_ASSCM/WORD fixes.
+
+	* eval.c (scm_lookupcar1): Inserted SCM_ASWORD in expressions
+	dealing with ilocs.
+
+2000-03-11  Dale P. Smith  <dpsm@en.com>, applied by Greg J. Badros, <gjb@cs.washington.edu>
+
+        * numbers.c (scm_copy_big_dec, scm_copy_smaller, scm_big_ior,
+        scm_big_xor, scm_big_and, scm_big_test): Added new lowlevel bignum
+        logical functions from SCM.
+
+        (logand, logior, logxor, logtest, logbit?): Extended scheme
+        logical functions to use bignums from SCM.
+
+        (lognot): Removed call to `SCM_VALIDATE_INUM' that prevented
+        lognot from using bignums.
+
+Thu Mar  9 11:33:25 2000  Greg J. Badros  <gjb@cs.washington.edu>
+
+	* vectors.h (SCM_VELTS_AS_STACKITEMS): Added this macro to help in
+	eliminating some warnings.
+
+	* unif.c, strports.c, print.c, options.c: Fix some warnings on
+ 	mis-use of SCM/long
+
+	* gc.c, gc.h: Added scm_return_first_int(), and added comment re:
+ 	what the scm_return_first* functions do.
+
+2000-03-09  Han-Wen Nienhuys  <hanwen@cs.uu.nl>, applied by Greg J. Badros, <gjb@cs.washington.edu>
+
+       * libguile/*.[ch]: make a distinction between SCM as a generic
+       name for a Scheme object (now a void*), and SCM as 32 bit word for
+       storing tags and immediates (now a long int).  Introduced
+       SCM_ASWORD and SCM_ASSCM for conversion. Fixed various dubious
+       code in the process: arbiter.c (use macros), unif.c (scm_array_p),
+
+Wed Mar  8 10:15:59 2000  Greg J. Badros  <gjb@cs.washington.edu>
+
+	* numbers.c:  Use SCM_VALIDATE_LONG_COPY, and longs, not ints, in
+	various logXXX primitives.  Thanks Eric Moore!
+
+Tue Mar  7 08:05:22 2000  Greg J. Badros  <gjb@cs.washington.edu>
+
+	* run-test, remaining-docs-needed:  Added these scripts.  The
+	second one is only temporary until the docstring additions are
+	complete.   run-test may best live on, but is here mostly for
+	convenience and awareness for now.
+
+	* hash.c: Docs, minor cleanup patch from Dirk Herrman.
+
+Thu Mar  2 16:06:58 2000  Greg J. Badros  <gjb@cs.washington.edu>
+
+	* error.h, error.c: Added `scm_wrong_type_arg_msg' to support
+ 	displaying the expected type.  Use SCM_LISTn in a couple places
+	instead of scm_cons-ing by hand.
+
+	* __scm.h: Added SCM_ASSERT_TYPE macro.
+
+	* validate.h, scm_validate.h: Added the former, as a renamed
+	version of the latter with SCM_ASSERT_TYPE used in
+	SCM_MAKE_VALIDATE (instead of just SCM_ASSERT)
+
+	* Makefile.am: Rename scm_validate.h to validate.h.
+
+	* *.c, *.h: Include validate.h, not scm_validate.h (old name's
+	prefix was superfluous).
+
+Thu Mar  2 15:33:12 2000  Greg J. Badros  <gjb@cs.washington.edu>
+
+	* hashtab.c: Improved documentation for lots of functions.  Added
+	handwritten docs for `hash-fold'.
+
+Thu Mar  2 15:13:25 2000  Greg J. Badros  <gjb@cs.washington.edu>
+
+	* list.c: Added hand-written docs for `del{q,v,ete}1!'.
+
+Thu Mar  2 12:38:30 2000  Greg J. Badros  <gjb@cs.washington.edu>
+
+	* list.c: Moved append docs to append! Thanks Dirk Hermann.  Also,
+	added append docs from R4RS.
+
+	* strings.c: Docstring typo fix, + eliminate unneeded IMP tests.
+	Thanks Dirk Hermann!
+
+	* chars.h: Provide SCM_CHARP, SCM_CHAR, SCM_MAKE_CHAR and
+	deprecate SCM_ICHRP, SCM_ICHR, SCM_MAKICHR.  Thanks Dirk Hermann!
+
+	* *.h, *.c: Use SCM_CHARP, SCM_CHAR, SCM_MAKE_CHAR throughout.
+	Drop use of SCM_P for function prototypes... assume an ANSI C
+	compiler.  Thanks Dirk Hermann!
+
+Sat Feb 19 12:20:12 2000  Greg J. Badros  <gjb@cs.washington.edu>
+
+	* ports.c: Made `set-port-column!' and `set-port-line!' each
+	return SCM_UNSPECIFIED instead of a (not-scheme-object) integer
+	that caused a seg fault.  Also fixed `set-port-column!'s
+	docstring.  Thanks Han-Wen Nienhuys for finding the bug!
+
+Sun Feb 13 19:11:42 2000  Greg J. Badros  <gjb@cs.washington.edu>
+

+	regex-posix.c, scmsigs.c, stime.c, strings.c, variable.c, stime.c,
+	strings.c, variable.c:  Added lots of documentation, cleaned up
+	some existing documentation.  Occasionally changed formal params
+	to match docs.  Also folded an #ifdef into the inners of a
+	primitive instead of having two copies of the primitive
+	(`get-internal-real-time', from stime.c)
+
+Sun Feb 13 18:12:19 2000  Greg J. Badros  <gjb@cs.washington.edu>

+	Michael Livshin.
+
+2000-02-09  Gary Houston  <ghouston@arglist.com>
+
+	* init.c (scm_init_standard_ports): when stdout is a tty, make the
+	current-output-port unbuffered by default.  this is less confusing
+	for interactive use.  it was line-buffered because of a
+	performance problem with unbuffered ports, but I think it will be
+	OK now.
+
+2000-02-08  Gary Houston  <ghouston@arglist.com>
+
+	* __scm.h: don't define long_long or ulong_long if HAVE_LONG_LONGS
+	is not defined.
+
+	* stime.c (scm_localtime, scm_mktime): if neither HAVE_TM_ZONE nor
+	HAVE_TZNAME are defined, use an empty string instead of giving two
+	spurious compile-time errors.
+
+Tue Feb  8 13:57:46 2000  Greg J. Badros  <gjb@cs.washington.edu>

+Mon Feb  7 09:07:31 2000  Greg J. Badros  <gjb@cs.washington.edu>
+
+	* macros.c: Doc patches from Richard Kim.  Pasted from scm.texi.
+
+Sun Feb  6 20:26:21 2000  Greg J. Badros  <gjb@cs.washington.edu>
+
+	* pairs.c: Doc patches from Richard Kim.  Pasted from MIT Scheme
+	(which is GNU GPL'd).
+
+2000-01-31  Gary Houston  <ghouston@arglist.com>
+
+	* strings.h: don't use SCM_P.  don't include <string.h>.
+	* error.c, gh_data.c, ports.c, script.c, strop.c: include <string.h>.
+
+	* strings.c (scm_string_ref): make the 2nd argument compulsory.
+	previously it defaulted to zero for no good reason that I can see.
+	use a local variable for SCM_INUM (k).  replace
+	SCM_VALIDATE_INUM_DEF with SCM_VALIDATE_INUM_COPY.
+
+	(scm_makfromstr): cosmetic changes.
+
+	(scm_string): Accept only chars in the list, not strings, for
+	conformance to R5RS (particularly for list->string, which is
+	supposed to be the inverse of string->list.)  remove
+	SCM_DEFER_INTS/SCM_ALLOW_INTS, which is unnecessary since
+	scm_makstr handles the cell allocation.  when reporting wrong-type
+	arg, don't report the position as 1.
+
+	* posix.c (scm_init_posix): intern PIPE_BUF if it's defined.
+
+2000-01-29  Gary Houston  <ghouston@arglist.com>
+
+	* posix.c (scm_pipe): rewrote the docstring.
+
+	* filesys.c (scm_select, retrieve_select_type, get_element,
+	fill_select_type, set_element): modified so that Scheme
+	"select" tests port buffers for the ability to provide input
+	or accept output.  Previously only the underlying file descriptors
+	were checked.  Rewrote the docstring.
+
+Thu Jan 27 10:14:25 2000  Greg J. Badros  <gjb@cs.washington.edu>
+
+	* vectors.c, symbols.c, strorder.c: Documentation cut and pasted
+ 	from Gregg Reynolds.  Thanks Gregg!
+
+Thu Jan 27 09:59:38 2000  Greg J. Badros  <gjb@cs.washington.edu>
+
+	* strop.c (scm_i_index): Obfuscated commented-out SCM_DEFINE by
+	adding "x" prefix to the line so that guile-func-name-check
+	doesn't complain unnecessarily.
+
+Wed Jan 26 17:33:52 2000  Greg J. Badros  <gjb@cs.washington.edu>
+
+	* throw.c: Factor out an #ifdef/#else/#endif choice more finely
+	for maintainability.
+
+	* strop.c: Documentation added by Gregg A. Reynolds.   Pasted in
+	from qdocs, RnRs.
+
+Wed Jan 26 10:02:11 2000  Greg J. Badros  <gjb@cs.washington.edu>
+
+	* tag.c:  Added doc for `tag', but mark as deprecated since Mikael
+	suggests removing tag.c altogether (and using a new `class-of'
+	instead).
+
+	* strings.c:  Added documentation from Gregg A. Reynolds.  Edited
+	a bit by me to use FOO instead of @var{foo} and to have the
+	summary come before preconditions on input.  Also dropped trailing
+	(rnrs) note.
+
+	* gsubr.c: Do not use SCM_DEFINE for `gsubr-apply'. Register the
+ 	function with scm_make_subr_opt w/ last arg of 0 so it is not
+ 	visible at the Scheme level. Mikael says that this is the right
+ 	thing because the first arg to the proc is the guts of a compiled
+ 	closure and shouldn't be exposed to the Scheme level.
+
+Tue Jan 25 17:15:47 2000  Greg J. Badros  <gjb@cs.washington.edu>
+
+	* sort.c: typo in comment fixed.
+
+	* keywords.c: Added documentation.
+
+	* guardians.c: Added documentation (could be better).
+
+	* gc.c: Added docs for gc-set-debug-check-freelist.
+
+	* eq.c: Added docs for eq?, eqv? equal? abridged from R4RS.
+
+	* boolean.c: Added docs for `not', `boolean?' (by hand).
+
+Tue Jan 25 13:28:56 2000  Greg J. Badros  <gjb@cs.washington.edu>
+
+	* random.c: Added documentation, from SLIB page:
+	http://angela.ctrl-c.liu.se/~calle/scheme/slib_toc.html
+
+Mon Jan 24 17:50:20 2000  Greg J. Badros  <gjb@cs.washington.edu>
+
+	* variable.c, version.c:  Added documentation, written by hand
+	since I could not find anything already written that was
+	relevant.
+
+2000-01-23  Gary Houston  <ghouston@arglist.com>
+
+	* filesys.c (scm_chown): omit port/fdes support if HAVE_FCHOWN is
+	not defined (thanks to Richard Y. Kim).
+
+Thu Jan 20 13:00:38 2000  Greg J. Badros  <gjb@cs.washington.edu>
+
+	* Makefile.in: Removed, this is auto-generated.
+
+Thu Jan 20 11:33:47 2000  Dirk Hermann <dirk@ida.ing.tu-bs.de> --applied 01/20/00 gjb
+
+	* list.c: Put some variable initialization code at the point of
+	declaration; Added a comment for list*; Formatting changes.
+
+	* load.c: use SCM_NNULLP to make sure the end of a list is not
+	reached yet.
+
+2000-01-18  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
+
+	* backtrace.c (scm_display_error_message): Bugfix: Don't use
+	result of scm_list_p as C boolean.
+	(scm_display_error_message, scm_set_print_params_x): Use new
+	validation macros. (Thanks to Dirk Herrmann.)
+
+	* net_db.c (scm_resolv_error): Cast result from hstrerror.
+
+	* strports.c (st_end_input): Inserted parenthesis to get operator
+	grouping correct.
+
+	* list.h (scm_init_list): Removed SCM_P around prototypes.
+
+	* fports.c, list.c, numbers.c, ports.c, stime.c, symbols.c,
+	filesys.c, posix.c: Converted docstrings to ANSI C format and
+	escaped " occurring inside string literals.
+
+Tue Jan 18 13:21:08 2000  Mikael Djurfeldt  <mdj@r11n07-s.pdc.kth.se>
+
+	* posix.c (scm_mknod): Escape " occuring inside docstring.
+
+2000-01-18  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
+
+	* alist.c, chars.c, debug.c, dynl.c, dynwind.c, error.c, eval.c,
+	   evalext.c, filesys.c, gc.c, hash.c, hashtab.c, ioext.c,

+	   symbols.c, throw.c, unif.c, vectors.c, version.c, vports.c,
+	   weaks.c: Converted docstrings to ANSI C format.
+
+	* filesys.c (scm_chmod), simpos.c (scm_system), version
+	(scm_version), vports (scm_make_soft_port): Escape " occuring
+	inside docstring.
+
+Mon Jan 17 11:41:22 2000  Greg J. Badros  <gjb@cs.washington.edu>
+
+	* scm_validate.h: Added SCM_VALIDATE_ULONG_COPY,
+	SCM_VALIDATE_LONG_COPY
+
+	* numbers.c: Use SCM_VALIDATE_ULONG_COPY, instead of
+	SCM_VALIDATE_INUM_COPY to let bigger numbers be used.  Rename a
+	couple of formal arguments (and fix their uses) to make arguments
+	match the documentation.
+
+2000-01-14    <mstachow@alum.mit.edu>
+
+	* Makefile.am: Augment path when running guile-doc-snarf so
+	guile-func-name-check is found.
+
+Fri Jan 14 09:34:55 2000  Greg J. Badros  <gjb@cs.washington.edu>
+
+	* scm_validate.h (SCM_NUM2LONG_DEF): Fix this macro to just use
+	def, not SCM_MAKINUM(def);  thanks Janis Bzerins!
+
+Wed Jan 12 00:06:53 2000  Greg J. Badros  <gjb@cs.washington.edu>
+
+	* net_db.c (s_scm_inet_makeaddr): Use SCM_NUM2ULONG since that's
+	the way guile-1.3.4 worked, but #if 0 out the version using
+	SCM_VALIDATE_INUM_COPY for stricter testing.
+
+Tue Jan 11 18:24:18 2000  Greg J. Badros  <gjb@cs.washington.edu>
+
+	* guile-doc-snarf.in: Use new $fullfilename for running
+	guile-func-name-check, and put "$fullfilename" and "$filename" in
+	quotes at uses to make sure re-splitting on whitespace does not
+	occur (so filenames w/ embedded whitespace would work okay, though
+	I sure hope we never have to deal with that! :-) ).  Thanks to
+	Mikael for pointing out the source_dir != build_dir was broken.
+
+Tue Jan 11 17:42:40 2000  Greg J. Badros  <gjb@cs.washington.edu>
+
+	* scm_validate.h: Added SCM_NUM2LONG_DEF macro.  Make
+	SCM_OUT_OF_RANGE use SCM_MAKINUM, not scm_long2num.  Added
+	SCM_COERCE_ROSTRING macro.  Added SCM_VALIDATE_NONEMPTYLIST
+	macro.  Fix SCM_VALIDATE_STRINGORSUBSTR macro to not use SLOPPY
+	variants.
+
+	* ports.c (scm_port_closed_p): Validate that the arg is a PORT,
+	then return whether it's an open port (was validating that it was
+	an open port -- this was a bug I introduced back in December, but
+	my careful reading of diffs caught it).
+
+	* numbers.c: Recombine the two conditional-compilation paths for
+	all the log* primitives -- they were split based on #ifndef
+	scm_long2num;  factored out a SCM_LOGOP_RETURN macro, and fixed
+	some bugs and inconsistencies in the two sets of implementations.
+	(scm_lognot) Fixed *atrocious* re-use of a SCM as an integer!
+
+	* ioext.c: Use SCM_ASSERT_RANGE in a couple places, and
+	SCM_VALIDATE_INUM_COPY once where it should've been used.
+
+	* fluids.c (scm_internal_with_fluids): Use
+	SCM_VALIDATE_LIST_COPYLEN.
+
+	* filesys.c: Use SCM_NUM2LONG instead of SCM_VALIDATE_INUM_COPY;
+	this is questionable as it relaxes type safety, but other changes
+	were useful and all SCM_NUM2LONG's should probably be
+	revisited. Use SCM_OUT_OF_RANGE, SCM_WRONG_TYPE_ARG.
+
+	* evalext.c: line-break change on 1 line.
+
+	* eval.c (nconc2last): Takes a non-empty list as its first
+	argument, not just a list.
+
+	* dynl.c: Use new SCM_COERCE_ROSTRING macro.
+
+Tue Jan 11 15:44:23 2000  Greg J. Badros  <gjb@cs.washington.edu>
+
+	* dynl.c, feature.c, filesys.c, fports.c, list.c, load.c,
+ 	net_db.c, sort.c, stacks.c, unif.c: Use SCM_WTA, SCM_MISC_ERROR
+ 	where possible.
+
+	* symbols.c (scm_sysintern0): Fixed the function name in a
+	scm_misc_error invocation.
+
+	* print.c (scm_simple_format): Do not need SCM_COERCE_SUBSTR, and
+	use scm_return_first to ward off latent GC bug that Mikael caught.
+
+	* async.c: Use SCM_VALIDATE_ASYNC_COPY one place where it wasn't
+	used before but should've been.
+
+2000-01-12  Mikael Djurfeldt  <mdj@thalamus.nada.kth.se>
+
+	* snarf.h (SCM_PROC1): Replaced SCM (*) (...) with
+	SCM_FUNC_CAST_ARBITRARY_ARGS.
+
+Tue Jan 11 13:44:07 2000  Greg J. Badros  <gjb@cs.washington.edu>
+
+	* guile-func-name-check.in: Added this script to statically check
+	#define FUNC_NAME, #undef FUNC_NAME in the source.
+
+	* sort.c, posix.c: Fix #undef FUNC_NAME lines to not have trailing
+	redundant comment, semicolon; caught by new guile-func-name-check
+	script.
+
+	* debug.c: Fix mistaken #define FUNC_NAME for scm_make_iloc.
+	Caught by new guile-func-name-check-script.
+
+	* Makefile.am: Added guile-func-name-check to bin_SCRIPTS
+
+	* ramap.c: Fix #if 0'd out code to be syntactically acceptable to
+	guile-func-name-check.
+
+	* guile-doc-snarf.in: Run guile-func-name-check on the file before
+	doing the snarf.
+
+Tue Jan 11 11:31:10 2000  Greg J. Badros  <gjb@cs.washington.edu>
+
+	* fports.c, ports.c, ports.h, strports.c, vports.c: Make write
+ 	port function take const void*, not void*.
+
+Tue Jan 11 11:18:07 2000  Greg J. Badros  <gjb@cs.washington.edu>
+
+	* scm_validate.h, chars.c, ports.c, print.c, read.c, strings.c,
+ 	strop.c: Use SCM_VALIDATE_ICHR, SCM_VALIDATE_ICHR_COPY instead of
+ 	SCM_VALIDATE_CHAR, SCM_VALIDATE_CHAR_COPY.  Change made for
+ 	consistency with the other macros dealing with immediate
+ 	characters.  (Similar to INT -> INUM change a week or so ago).
+
+Tue Jan 11 10:41:46 2000  Greg J. Badros  <gjb@cs.washington.edu>
+
+	* dynl.c, error.c, eval.c, feature.c, filesys.c, fports.c, list.c, load.c,
+ 	net_db.c, read.c, socket.c: Update error messages to use ~A for
+ 	%s, ~S for %S to work with new `simple-format' format and be
+ 	standardized better.
+
+	* print.h, print.c (scm_simple_format): Added `simple-format'
+	primitive.  It's the old scm_display_error, with ARGS now a rest
+	parameter, and the destination first instead of last (and a couple
+	new capabilities inspired by `format' -- #t as destination means
+	current-output-port, #f means return the formatted text as a
+	string.
+
+	* gh.h, gh_data.c, ports.h, ports.c: Added some missing const specifications.
+
+	* backtrace.c (scm_display_error_message): Rewrote to use
+	scm_simple_format() procedure.
+
+	* __scm.h: Added commented-out #define of GUILE_DEBUG_FREELIST
+
+2000-01-09  Marius Vollmer  <mvo@zagadka.ping.de>
+
+ 	Finally applied the libltdl patch from Thomas Tanner, with slight
+	modifications.
+
+	* DYNAMIC-LINKING: Removed because it is obsolete.
+	* dynl.c: Use ANSI prototypes.
+	(sysdep_dynl_link): Use lt_dlopenext instead of lt_dlopen.
+	* scmconfig.h.in: Do not change, as it is automatically generated.
+
+    1999-07-25  Thomas Tanner  <tanner@ffii.org>
+
+	    * dynl-dl.c, dynl-dld.c, dynl-shl.c, dynl-vms.c: deleted
+	    (obsolete)
+	    * Makefile.am: likewise, add INCLTDL (libltdl headers) to
+	    INCLUDES, set dlpreopened files in LDFLAGS, link libguile
+	    against libltdl
+	    * dynl.c: use libltdl if DYNAMIC_LINKING is enabled,
+	    * guile.c: register preloaded modules
+	    * scmconfig.h.in: remove obsolete symbols
+
+2000-01-09  Gary Houston  <ghouston@arglist.com>
+
+	* These changes should make it unnecessary to call tzset from
+	Scheme after modifying the TZ environment variable, even if the
+	system date facilities cache the value.
+	* stime.c (setzone, scm_localtime): added comments.
+	(tzset): don't define a noop tzset macro if HAVE_TZSET not defined.
+	(setzone): don't call tzset.
+	(restorezone): call tzset only if HAVE_TZSET is defined.
+	(scm_tzset): don't define if HAVE_TZSET not defined.  Change the
+	doc string to indicate that this procedure isn't likely to do
+	anything useful.
+	(scm_localtime, scm_strftime, scm_mktime): call tzset if
+	LOCALTIME_CACHE is defined.
+
+2000-01-09  Mikael Djurfeldt  <mdj@thalamus.nada.kth.se>
+
+	* posix.c (scm_sync): Return SCM_UNSPECIFIED.
+
+2000-01-09  Gary Houston  <ghouston@arglist.com>
+
+	* eval.c: define scm_unbound_variable_key ('unbound-variable).
+	scm_lookupcar1: throw an error with key 'unbound-variable instead
+	of 'misc-error when an unbound variable is encountered.
+
+	* filesys.c (scm_mkdir, scm_rmdir, scm_getcwd, scm_select,
+	scm_symlink, scm_readlink, scm_lstat),
+	posix.c (scm_setpgid, scm_setsid, scm_ctermid, scm_tcgetpgrp,
+	scm_tcsetpgrp, scm_uname, scm_setlocale, scm_mknod, scm_nice,
+	scm_sync),
+	simpos.c (scm_system),
+	stime.c (scm_times, scm_strptime):
+	move the HAVE_XXX feature tests out of the procedure bodies.
+	don't use SCM_SYSMISSING.
+	scm_validate.h (SCM_SYSMISSING): removed.
+	error.h, error.c (scm_sysmissing): comment that this is deprecated.
+	see ChangeLog entry for 1999-12-28.
+
+Sat Jan  8 19:52:04 2000  Greg J. Badros  <gjb@cs.washington.edu>
+
+	* scm_validate.h (SCM_VALIDATE_BOOL_COPY): Fix typo.
+
+Sat Jan  8 17:06:46 2000  Greg J. Badros  <gjb@cs.washington.edu>
+
+	* backtrace.c: Fix spelling typo in a comment.
+
+	* snarf.h: Use new SCM_DOCS macro to encapsulate the non SCM_INIT
+ 	text.  Reformatted some of the expansions.
+
+Fri Jan  7 15:50:46 2000  Greg J. Badros  <gjb@cs.washington.edu>
+
+	* scm_validate.h (SCM_OUT_OF_RANGE): Use scm_out_of_range_pos to
+	report the position of the argument.
+
+	* error.h, error.c (scm_out_of_range_pos):  Added this function to
+	take extra "pos" argument, the position number of the errant
+	argument.
+
+	* debug.c: Use SCM_OUT_OF_RANGE instead of scm_out_of_range.
+
+	* snarf.h: Use SCM_HERE and SCM_INIT as names, not SCM_NOTSNARF
+	and SCM_SNARFING.  Also put the %%% in the SCM_INIT since Mikael
+	prefers that and I'm reasonably indifferent.
+
+Fri Jan  7 15:03:32 2000  Greg J. Badros  <gjb@cs.washington.edu>
+
+	* snarf.h: Factor out differences between C++ and non-C++ into
+	SCM_FUNC_CAST_ARBITRARY_ARGS macro.  Modify all the snarf macro
+	definitions to use SCM_NOTSNARF and SCM_SNARFING macros (like
+	Mikael's macros, below, but changed names and SCM_SNARFING no
+	longer expands to include %%% -- that must appear in the argument
+	so that the token appears at the call-site as a reminder).
+
+2000-01-07  Mikael Djurfeldt  <mdj@thalamus.nada.kth.se>
+
+	* snarf.h (SCM_INSITU, SCM_INIT): New snarf macros for use in user
+	snarf macro definitions.
+
+2000-01-06  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>
+
+	* chars.c (scm_integer_to_char): Use Greg's nice
+	SCM_VALIDATE_INUM_RANGE macro for argument checking for closer
+	adherence to R5RS.
+
+Thu Jan  6 11:48:49 2000  Greg J. Badros  <gjb@cs.washington.edu>
+
+	* *.c, snarf.h: Replace GUILE_PROC1 with SCM_DEFINE1 throughout.
+
+Thu Jan  6 11:22:53 2000  Greg J. Badros  <gjb@cs.washington.edu>
+
+	* Makefile.am (ETAGS_ARGS): Switch to SCM_DEFINE, SCM_DEFINE1
+	instead of GUILE_PROC.
+
+Thu Jan  6 11:21:49 2000  Greg J. Badros  <gjb@cs.washington.edu>
+
+	* alist.c: Do not report mismatch errors on some uses of `tmp' (do
+	this by using SCM_ARG2 instead of `2' in the SCM_VALIDATE_CONS
+	macro call.
+
+Thu Jan  6 09:54:33 2000  Dirk Herrmann <dirk@ida.ing.tu-bs.de> --gjb applied
+
+	* scm_validate.h: Remove some redundant NIMP tests.
+
+	* alist.c: minimize scope of the tmp variables, and initialize
+ 	them when declared. The strange SCM_NIMP tests are replaced by
+ 	SCM_CONSP tests that more closely reflect the intended semantics.
+  	However, we don't get a performance penalty here, because the
+ 	SCM_CONSP test was performed by the ALISTCELL test anyway.  * The
+ 	extremely ugly use of ASRTGO macros was removed: The calls to
+ 	ASRTGO were not encapsulated by "#ifndef SCM_RECKLESS", but got a
+ 	label parameter that only exists when SCM_RECKLESS is not defined.
+  	This works, because ASRTGO itself is defined in a way that it only
+ 	makes use of the label parameter if SCM_RECKLESS is not defined
+ 	(shudder!).  Does guile make at all use of the possibility to
+ 	define SCM_RECKLESS?  * Codesize is likely to be reduced, since
+ 	instead of two calls to SCM_ASSERT performed by the ALISTCELL test
+ 	we now only get one test.
+
+	* list.c: Use SCM_NNULLP, not SCM_NIMP as appropriate.  Also use
+ 	SCM_NULLP instead of SCM_IMP.  Drop use of "register" keyword on
+ 	some variables in `list?'.  Fix `reverse' and `reverse!'
+ 	primitives to handle improper lists better.
+
+Wed Jan  5 11:24:53 2000  Greg J. Badros  <gjb@cs.washington.edu>
+
+	* *.[ch]: Whitespace changes -- added space after SCM_VALIDATE_*
+ 	macros and SCM_DEFINE macros to match GNU coding standards.
+
+Wed Jan  5 11:04:24 2000  Greg J. Badros  <gjb@cs.washington.edu>
+
+	* *.[ch]: Replace GUILE_PROC w/ SCM_DEFINE.
+
+Wed Jan  5 10:59:06 2000  Greg J. Badros  <gjb@cs.washington.edu>
+
+	* *.[ch]:  Replace SCM_VALIDATE_INT w/ SCM_VALIDATE_INUM for
+	better consistency with the names of other SCM_VALIDATE_ macros
+	and better conformance to guile naming policy.
+
+Wed Jan  5 10:50:39 2000  Greg J. Badros  <gjb@cs.washington.edu>
+
+	* ports.c (s_scm_close_all_ports_except): Use SCM_ARG1 in a
+	SCM_VALIDATE instead of 1 to avoid a check on the argument (since
+	it's not the actual name of the formal).
+
+	* guile-snarf.awk.in: Do argument/number mismatch checking and
+	print warnings in an Emacs compile-mode parseable format.
+
+	* struct.c: Use SCM_ASSERT_RANGE instead of SCM_ASSERT w/
+	SCM_OUTOFRANGE as 3rd argument.
+
+	* random.c: Fix argument/number mismatch (that I introduced :-( ).
+
+	* __scm.h: Do not #define SCM_ARG* when snarfing;
+	lets us distinguish between 1 and SCM_ARG1 when snarfing as only
+	the former (using the number) requires the argument to match the
+	formal in the current argument snarfing check.
+
+	* snarf.h: Give new definition of SCM_ASSERT when in
+	snarfing mode to output a lexically-identifiable sequence that the
+	guile-snarf.awk script uses to verify argument/position matching.
+
+	* ramap.c: Remove extraneous #undef FUNC_NAME.
+
+Wed Jan  5 08:36:38 2000  Greg J. Badros  <gjb@cs.washington.edu>
+
+	* guile-doc-snarf.awk.in: Removed -- guile-snarf.awk.in is the
+	current version of the same functionality; it writes the .x output
+	to stdout instead of directly into the file.
+
+Wed Jan  5 08:15:04 2000  Greg J. Badros  <gjb@cs.washington.edu>
+
+	* unif.c, symbols.c, strings.c, stacks.c, random.c, print.c,
+	posix.c:  Eliminated a bunch of SCM_NIMP(..)s that are now
+	redundant with the safer macros.  Patch from Dirk Hermann applied
