+	    Ludovic Courtès  <ludo@gnu.org>
+
+	* goops.c (scm_init_goops_builtins, go_to_hell): Fix allocation

+
+2008-08-02  Neil Jerram  <neil@ossau.uklinux.net>
+
+	* numbers.c (scm_rationalize): Update docstring to match the
+	manual (which is more correct).  Change argument "err" to "eps",
+	also to match the manual.
+

+
+2008-07-04  Ludovic Courtès  <ludo@gnu.org>
+
+	* posix.h (scm_i_locale_mutex): Don't declare as `SCM_INTERNAL'
+	since it's needed by `libguile-i18n'.  Reported by Patrick
+	Horgan <phorgan1@gmail.com>.
+
+	* __scm.h (SCM_INTERNAL): Add `extern' so that these symbols are
+	not considered as "common" by GCC 4.3.  Reported by Patrick
+	Horgan <phorgan1@gmail.com>.
+
+2008-06-28  Ludovic Courtès  <ludo@gnu.org>
+
+	* Makefile.am (INCLUDES): Renamed to...
+	(AM_CPPFLAGS): this, to match current Automake conventions.
+	Users updated.
+
+	* tags.h (SCM_UNPACK): Disable type-checking for `__DECC' and
+	`__HP_cc'.  Reported by Peter O'Gorman <pogma@thewrittenword.com>.
+
+2008-06-02  Ludovic Courtès  <ludo@gnu.org>
+
+	* deprecated.c (maybe_close_port): Rename EXCEPT to EXCEPT_SET
+	to workaround `#define except' on Tru64.  Reported by Peter
+	O'Gorman <pogma@thewrittenword.com>.
+
+2008-05-31  Ludovic Courtès  <ludo@gnu.org>
+
+	* __scm.h (SCM_INTERNAL): New macro.
+	* *.h: Use it to mark as internal `scm_i_' and `scm_init_'
+	functions that are not used by public macros or inline
+	functions.
+
+2008-05-14  Julian Graham  <joolean@gmail.com>
+
+	* threads.c (fat_mutex)[recursive]: New field.
+	(make_fat_mutex): Adjust initialization to reflect changes to
+	mutex lock level semantics.
+	(fat_mutex_lock, fat_mutex_unlock): Add support for unowned
+	mutexes and locking mutexes on behalf of other threads.
+	(scm_lock_mutex, scm_lock_mutex_timed): Update to reflect
+	signature change to fat_mutex_lock.
+	(scm_mutex_owner, scm_mutex_level, scm_mutex_locked_p): New /
+	re-enabled functions.
+	* threads.h (scm_mutex_owner, scm_mutex_level,
+	scm_mutex_locked_p): Prototypes for new functions.
+
+2008-05-12  Neil Jerram  <neil@ossau.uklinux.net>
+
+	* discouraged.c: Expand DEFFROM and DEFTO macros, to avoid
+	compiler warnings about excess semicolons.  (Reported by Didier
+	Godefroy.)
+
+2008-05-08  Neil Jerram  <neil@ossau.uklinux.net>
+
+	* throw.c (scm_ithrow): For IA64 add a return statement, to
+	appease GCC.
+
+	* threads.h (scm_i_thread): New IA64 fields:
+	register_backing_store_base and pending_rbs_continuation.
+
+	* threads.c (guilify_self_1): For IA64: cap RBS base address at
+	the current value of scm_ia64_ar_bsp, and store the capped value
+	in thread state.
+	(SCM_MARK_BACKING_STORE): Use thread->register_backing_store_base
+	instead of scm_ia64_register_backing_store_base().
+	(scm_threads_mark_stacks): Add "&" in "&t->regs", so that the code
+	works both for jmp_buf defined as an array, and jmp_buf defined as
+	a struct.
+
+	* continuations.h (scm_t_contregs): Remove `fresh' and `ctx'
+	fields; these are now inside the IA64 definition of `jmp_buf'.
+
+	* continuations.c (scm_make_continuation): Simplify, by moving
+	some of the IA64 code inside the definition of "setjmp", and by
+	some obvious commonizations.  For IA64 register backing store
+	(RBS) stack base, use thread->register_backing_store_base instead
+	of scm_ia64_register_backing_store_base().
+	(copy_stack): For IA64, store pointer to continuation being
+	invoked in thread state, so we can restore the continuation's RBS
+	stack just before the next setcontext call.
+	(copy_stack_and_call): Don't restore RBS stack explicitly here.
+	It will be restored, if appropriate, inside the longjmp call.
+	(scm_ia64_longjmp): New function.
+
+	* __scm.h (setjmp, longjmp, jmp_buf): For IA64, implement using
+	getcontext and setcontext.
+
+2008-05-07  Ludovic Courtès  <ludo@gnu.org>
+
+	* numbers.c (scm_from_complex_double): Mark as `SCM_UNUSED'.
+	This fixes compilation with `-Werror' on FreeBSD 6.2 (i386).
+
+2008-05-05  Neil Jerram  <neil@ossau.uklinux.net>
+
+	* c-tokenize.lex: #define YY_NO_INPUT.
+
+2008-04-26  Ludovic Courtès  <ludo@gnu.org>
+
+	* read.c (scm_read_sexp): Remove extraneous semi-colon at
+	end-of-line, which broke compilation with GCC 2.7.  Reported by
+	Alain Guibert <alguibert+bts@free.fr>.
+
+2008-04-24  Ludovic Courtès  <ludo@gnu.org>
+
+	* Makefile.am (DEFAULT_INCLUDES): New.  Fixes compilation on
+	Tru64 where our "random.h" would shadown libc's one.
+	(INCLUDES): Add "-I$(top_buildir)", which is normally in
+	`DEFAULT_INCLUDES'.
+	* gen-scmconfig.c: Include <libguile/gen-scmconfig.h>, not
+	"gen-scmconfig.h" since that file is under `$(builddir)'.
+
+2008-04-16  Ludovic Courtès  <ludo@gnu.org>
+
+	* ports.c (scm_getc, scm_putc, scm_puts): Moved...
+	* inline.h: ... here.  Noticeably improves `read' performance.
+
+2008-04-15  Ludovic Courtès  <ludo@gnu.org>
+	    Julian Graham  <joolean@gmail.com>
+
+	* read.c (scm_keyword_postfix): New.
+	(scm_read_opts): Update docstring for `keywords'.
+	(scm_read_mixed_case_symbol): Add support for postfix keywords.
+
+2008-04-13  Ludovic Courtès  <ludo@gnu.org>
+
+	* inline.h (SCM_C_USE_EXTERN_INLINE): New macro.  Use it to make
+	sure "extern" declarations are produced when "extern inline" is
+	used.  Simplify macrology around inline definitions.
+
+2008-04-10  Ludovic Courtès  <ludo@gnu.org>
+
+	* inline.h (SCM_C_EXTERN_INLINE): Special-case Apple's GCC
+	4.0-based compiler, which doesn't support GNU inline semantics
+	at all in C99 mode but doesn't define `__GNUC_STDC_INLINE__'.
+	See http://thread.gmane.org/gmane.network.gnutls.general/1135 .
+
+2008-04-10  Andy Wingo  <wingo@pobox.com>
+
+	* struct.c (scm_struct_ref, scm_struct_set_x): "Light" structs
+	have no hidden words (members of the SCM_STRUCT_DATA(x) array
+	accessed with negative indices). In that case, determine the
+	number of fields from the length of the struct layout
+	descriptor. (Most GOOPS instances are light structs.)
+
+	* goops.c (wrap_init): Initialize 'u' slots to 0, not some random
+	SCM value.
+
+	* goops.c (get_slot_value, set_slot_value): In the struct
+	allocation case, don't poke the slots array directly -- we should
+	go through struct-ref/struct-set! code so that we get the
+	permissions and allocation ('u' versus 'p') correct.
+
+2008-04-03  Ludovic Courtès  <ludo@gnu.org>
+
+	* inline.h (SCM_C_EXTERN_INLINE): New macro, addresses the
+	"extern inline" semantic change in C99 mode with GCC 4.3 and
+	later and the warning in C99 mode with GCC 4.2.  Use it in the
+	inline function definitions.
+
+2008-03-24  Neil Jerram  <neil@ossau.uklinux.net>
+
+	Applying patch from Julian Graham, containing minor fixes to his
+	thread enhancements:
+
+	* threads.c (to_timespec): Change 1000000 multiplier to
+	1000000000.
+	(unchecked_unlock_sym, allow_external_unlock_sym,
+	recursive_sym): Use SCM_SYMBOL.
+	(scm_make_mutex_with_flags): When raising unsupported option
+	error, report what the unsupported option was.
+	(fat_mutex_unlock): When raising errors, unlock m->lock first.
+	(fat_cond_timedwait): Removed.
+	(scm_timed_wait_condition_variable): Call fat_mutex_unlock
+	directly instead of via fat_cond_timedwait.
+
+2008-03-10  Ludovic Courtès  <ludo@gnu.org>
+
+	* eval.c, filesys.c: Enclose `alloca' blob in `#ifndef alloca',
+	as per Gnulib's `alloca'.  This should fix compilation on
+	FreeBSD 6.
+
+2008-03-09  Neil Jerram  <neil@ossau.uklinux.net>
+
+	* numbers.c: Only define scm_from_complex_double if it will
+	actually be used.
+
+2008-03-08  Julian Graham  <joolean@gmail.com>
+
+	* threads.c (scm_join_thread_timed, scm_thread_p,
+	scm_make_mutex_with_flags, scm_lock_mutex_timed,
+	scm_unlock_mutex_timed, scm_mutex_p, scm_condition_variable_p): New
+	functions.
+	(thread_mark): Updated to mark new struct field `mutexes'.
+	(do_thread_exit): Notify threads waiting on mutexes locked by exiting
+	thread.
+	(scm_join_thread, scm_make_mutex, scm_make_recursive_mutex,
+	scm_mutex_lock): Reimplement in terms of their newer
+	counterparts.
+	(scm_abandoned_mutex_error_key): New symbol.
+	(fat_mutex)[unchecked_unlock, allow_external_unlock]: New fields.
+	(fat_mutex_lock): Reimplement to support timeouts and abandonment.
+	(fat_mutex_trylock, scm_try_mutex): Remove fat_mutex_trylock and
+	reimplement scm_try_mutex as a lock attempt with a timeout of zero.
+	(fat_mutex_unlock): Allow unlocking from other threads and unchecked
+	unlocking; implement in terms of condition variable wait.
+	(scm_timed_wait_condition_variable): Reimplement in terms of
+	fat_mutex_unlock.
+	* threads.h (scm_i_thread)[mutexes]: New field.
+	(scm_join_thread_timed, scm_thread_p, scm_lock_mutex_timed,
+	scm_unlock_mutex_timed, scm_mutex_p, scm_condition_variable_p):
+	Prototypes for new functions.
+
+2008-03-06  Ludovic Courtès  <ludo@gnu.org>
+
+	* eval.c (scm_eval): If MODULE_OR_STATE is not a dynamic state,
+	make sure it's a module.  Reported by David I. Lehn.
+
+2008-03-02  Ludovic Courtès  <ludo@gnu.org>
+
+	* pairs.h (scm_is_pair): Moved declaration to `inline.h'.
+	* inline.h: Make sure `extern' declarations are not produced
+	when `inline' is supported but GCC is not used.  This
+	fixes "mixed linkage" errors with compilers such as
+	DEC/Compaq/HP CC.
+
+2008-02-27  Neil Jerram  <neil@ossau.uklinux.net>
+
+	* _scm.h (errno): Remove declarations that have been there
+	forever, and are known to conflict on some platforms with that
+	provided by <errno.h>, which we include unconditionally.  If
+	<errno.h> doesn't provide a errno declaration, what is the point
+	of it?
+
+2008-02-23  Ludovic Courtès  <ludo@gnu.org>
+
+	* numbers.c (scm_make_rectangular): Rename argument to
+	`real_part' and `imaginary_part' to work around Solaris 2.10
+	headers which define `imaginary' as a macro.  Patch by Tim
+	Mooney <mooney@dogbert.cc.ndsu.NoDak.edu>.
+
+2008-02-22  Ludovic Courtès  <ludo@gnu.org>
+
+	* read.c (strncasecmp): Add declaration when
+	`HAVE_DECL_STRNCASECMP' is undefined.  Fixes compilation on
+	NetBSD 1.6.
+
+	* gc.c (scm_ia64_ar_bsp)[linux]: Don't discard `const' qualifier
+	of OPAQUE.
+
+2008-02-21  Ludovic Courtès  <ludo@gnu.org>
+
+	Fix bug #22369.
+
+	* goops.c (scm_add_slot): Add `SCM_UNDEFINED' as last argument

+
+	* script.c (scm_compile_shell_switches): Update copyright year.
+
+2008-02-16  Ludovic Courtès  <ludo@gnu.org>

+
+2008-02-12  Ludovic Courtès  <ludo@gnu.org>
+
+	* guile-snarf.in (tempdir): Honor `$TMPDIR'.
+
+2008-02-11  Neil Jerram  <neil@ossau.uklinux.net>
+
+	* numbers.c (SCM_COMPLEX_VALUE): Use GUILE_I instead of _Complex_I
+	directly, and only if GUILE_I was defined by the configure step.
+	(scm_log, scm_log10, scm_exp, scm_sqrt): Use SCM_COMPLEX_VALUE
+	code only if SCM_COMPLEX_VALUE is defined.
+
+2008-02-07  Ludovic Courtès  <ludo@gnu.org>
+
+	Fix bug #21378.
+	Thanks to David Diffenbaugh <davediff@nbcs.rutgers.edu>.
+
+	* read.c (scm_read_quote): Don't use `__FUNCTION__' since it is
+	not supported by Sun CC on Solaris 9.
+	(scm_read_keyword): Likewise.
+	* strings.c (scm_take_locale_stringn): Remove
+	`SCM_C_INLINE_KEYWORD' to allow compilation with Sun CC.
+
+2008-02-07  Julian Graham  <joolean@gmail.com>
+
+	* threads.c (do_thread_exit, scm_cancel_thread,
+	scm_set_thread_cleanup_x, scm_thread_cleanup): Lock on thread-specific
+	admin mutex instead of `thread_admin_mutex'.
+	* threads.h (scm_i_thread)[admin_mutex]: New field.
+	* throw.c (make_jmpbuf): Don't enter critical section during thread
+	spawn -- there is a possibility of deadlock if other threads are
+	exiting.
+
+2008-02-06  Neil Jerram  <neil@ossau.uklinux.net>
+
+	* gc-malloc.c (scm_gc_malloc): Return NULL if requested size is 0.

+	* numbers.c (scm_i_mkbig, scm_i_long2big, scm_i_ulong2big,
+	scm_i_clonebig, scm_i_bigcmp, scm_i_dbl2big, scm_i_dbl2num,
+	scm_i_normbig): Remove `SCM_C_INLINE_KEYWORD' since these are
+	declared as `extern' in `numbers.h'.  This precluded compilation
+	on Solaris 9 with Sun CC (reported by David Halik
+	<dhalik@nbcs.rutgers.edu>).
+
+2008-02-05  Neil Jerram  <neil@ossau.uklinux.net>
+
+	* fports.c (fport_seek): Make dependent on GUILE_USE_64_CALLS.

+	(Thanks to Gregory Marton for reporting this.)
+
+2007-12-29  Neil Jerram  <neil@ossau.uklinux.net>
+
+	* gc.c (mark_gc_async): Change "func_data" to "fn_data", to avoid

+
+2007-12-08  Ludovic Courtès  <ludo@gnu.org>
+

+	(SCM_ASSERT, SCM_ASSERT_TYPE, SCM_ASRTGO, SCM_GASSERT0,
+	SCM_GASSERT1, SCM_GASSERT2, SCM_GASSERTn): Use them.
+	* eval.c (ASSERT_SYNTAX, ASSERT_SYNTAX_2): Likewise.

+2007-10-27  Ludovic Courtès  <ludo@gnu.org>
+
+	* fports.c (scm_i_evict_port): Expect a port, rather than a pair

+	`leave_locale_section ()' on failure of
+	`enter_locale_section ()' since the mutex is not held and locale
+	settings are unchanged.
+	(scm_nl_langinfo)[!USE_GNU_LOCALE_API]: Use
+	`restore_locale_settings ()' instead of `leave_locale_section ()'
+	since the mutex is not held.
+
+2007-10-02  Ludovic Courtès  <ludo@gnu.org>
+
+	* threads.c (on_thread_exit): Don't call `scm_leave_guile ()'
+	since we're already in non-guile mode.  Reported by Greg Toxel
+	for NetBSD.
+
+2007-10-01  Ludovic Courtès  <ludo@gnu.org>
+
+	* ports.c (flush_output_port): Expect directly a port instead of
+	a pair.  Fixes a bug in the new port table (2007-08-26).
+
+2007-09-11  Kevin Ryde  <user42@zip.com.au>
+
+	* posix.c (scm_putenv): Confine the putenv("NAME=") bit to mingw, use
+	putenv("NAME") as the fallback everywhere else.  In particular this is
+	needed for solaris 9.  Reported by Frank Storbeck.
+
+2007-09-03  Ludovic Courtès  <ludo@gnu.org>
+
+	* read.c (flush_ws): Handle SCSH block comments.
+
+2007-09-03  Ludovic Courtès  <ludo@gnu.org>
+
+	Fix alignment issues which showed up at least on SPARC.
+
+	* socket.c (scm_t_max_sockaddr, scm_t_getsockopt_result): New.
+	(scm_inet_pton): Change DST to `scm_t_uint32' for correct
+	alignment.
+	(scm_getsockopt): Change OPTVAL to `scm_t_getsockopt_result' for
+	correct alignment.
+	(_scm_from_sockaddr): Change ADDRESS to `scm_t_max_sockaddr *'.
+	(scm_from_sockaddr): Cast ADDRESS to `scm_t_max_sockaddr *'.
+	(MAX_SIZE_UN, MAX_SIZE_IN6): Removed.
+	(scm_accept, scm_getsockname, scm_getpeername, scm_recvfrom):
+	Use `scm_t_max_sockaddr' instead of "char max_addr[MAX_ADDR_SIZE]".
+
+2007-09-03  Kevin Ryde  <user42@zip.com.au>
+
+	* numbers.c (scm_log): Test HAVE_CLOG as well as HAVE_COMPLEX_DOUBLE
+	before using clog().  It's possible for gcc to provide the "complex
+	double" type, but for the system not to have the complex funcs.
+	(scm_exp): Ditto HAVE_CEXP for cexp().
+	(clog, cexp, carg): Remove fallback definitions.  These only
+	duplicated the code within scm_log and scm_exp, and the latter have to
+	exist for the case when there's no "complex double".  So better just
+	fix up the conditionals selecting between the complex funcs and plain
+	doubles than worry about fallbacks.
+
+2007-09-02  Ludovic Courtès  <ludo@gnu.org>
+
+	* socket.c (scm_make_socket_address): Free C_ADDRESS after use.
+	This fixes a memory leak.
+
+2007-08-26  Han-Wen Nienhuys  <hanwen@lilypond.org>
+
+	* fports.c gc-card.c gc.c gc.h ioext.c ports.c ports.h weaks.h
+	gc.c: replace port table with weak hash table. This simplifies
+	memory management, and fixes freed cells appearing in
+	port-for-each output.
+
+	* init.c (cleanup_for_exit): abort cleanup if init_mutex is still
+	held.
+
+2007-08-23  Ludovic Courtès  <ludo@gnu.org>
+
+	* read.c (scm_read_quote): Record position and copy source
+	expression when asked to.  Reported by Kevin.
+
+	* stime.c: Define `_REENTRANT' only if not already defined.
+
+2007-08-21  Kevin Ryde  <user42@zip.com.au>
+
+	* gc-card.c (scm_i_card_statistics): Record scm_tc7_number types as
+	tc16 values so big, real, complex and fraction can be distinguished.
+
+	(scm_i_tag_name): Return "number" for scm_tc7_number, not NULL.  NULL
+	was making numbers come out as "type 23" in gc-live-object-stats.
+	Fix tests of the tc16 number types, they were checked under
+	scm_tc7_number, but the values went down the tag>=255 smob case.
+	Put smob case under scm_tc7_smob instead of using tag>=255, per
+	recommendation in comments with scm_tc7_smob to use symbolic values.
+	Use SCM_TC2SMOBNUM to extract scm_smobs index, instead of explicit
+	code.  Lose some unnecessary "break" statements.
+
+	(scm_i_card_statistics): Use scm_hashq_create_handle_x and modify the
+	element returned, rather than two lookups scm_hashq_ref and
+	scm_hashq_set_x.
+
+2007-08-17  Kevin Ryde  <user42@zip.com.au>
+
+	* stime.c: Add #define _REENTRANT, to get gmtime_r() prototype on
+	solaris 2.6.  Reported by anirkko.
+
+2007-07-29  Ludovic Courtès  <ludo@gnu.org>
+
+	* Makefile.am (INCLUDES): Added Gnulib includes.
+	(gnulib_library): New.
+	(libguile_i18n_v_@LIBGUILE_I18N_MAJOR@_la_LIBADD): Added
+	`$(gnulib_library)'.
+	(libguile_la_LIBADD): Likewise.
+
+	* posix.c: Don't define `_GNU_SOURCE' since `gl_EARLY' arranges
+	to define it when available.
+	* srfi-14.c: Likewise.
+	* i18n.c: Likewise.  Include Gnulib's <alloca.h>
+	* eval.c: Include Gnulib's <alloca.h>.
+	* filesys.c: Likewise.
+	* read.c: Don't include <strings.h> and don't provide an
+	`strncasecmp ()' replacement; use Gnulib's <string.h> and
+	`strncasecmp ()' instead.
+
+2007-07-25  Ludovic Courtès  <ludo@gnu.org>
+
+	* eval.c (macroexp): When `scm_ilength (res) <= 0', return
+	immediately.  This used to produce a circular memoized
+	expression, e.g., for `(set (quote x) #t)'.
+
+2007-07-22  Ludovic Courtès  <ludo@gnu.org>
+
+	Overhauled the reader, making it faster.
+
+	* gdbint.c (tok_buf, tok_buf_mark_p): Removed.
+	(gdb_read): Don't use a token buffer.  Use `scm_read ()' instead
+	of `scm_lreadr ()'.
+
+	* read.c: Overhauled.  No longer use a token buffer.  Use a
+	on-stack C buffer in the common case and use Scheme strings when
+	larger buffers are needed.
+	* read.h (scm_grow_tok_buf, scm_flush_ws, scm_casei_streq,
+	scm_lreadr, scm_lreadrecparen): Removed.
+	(scm_i_input_error): Marked as `SCM_NORETURN'.
+
+2007-07-15  Ludovic Courtès  <ludo@gnu.org>
+
+	* script.c (scm_compile_shell_switches): Updated copyright year.
+
+2007-07-11  Ludovic Courtès  <ludo@gnu.org>
+
+	* goops.c (scm_sys_method_more_specific_p): Added docstring.
+	Make sure LEN is greater than or equal to the minimum length of
+	specializers of M1 and M2.  This fixes a segfault later on in
+	`more_specificp ()' if TARGS is too small.  Reported by Marco
+	Maggi <marco.maggi-ipsu@poste.it>.
+
+2007-06-26  Ludovic Courtès  <ludo@gnu.org>
+
+	* fluids.c (next_fluid_num): When growing ALLOCATED_FLUIDS, make
+	sure to free the previous array after the new one has been
+	installed.  This leak is made visible by running
+	"(define l (map (lambda (i) (make-fluid)) (iota 255)))"
+	from the REPL within Valgrind.
+
+2007-06-12  Ludovic Courtès  <ludo@chbouib.org>
+
+	* socket.c (scm_inet_ntop): In the `AF_INET' case, declare `addr4'
+	as an `scm_t_uint32' rather than re-using `addr6'.  This fixes a
+	bus error on SPARC (and possibly others) due to unaligned access.
+
+2007-06-07  Ludovic Courtès  <ludovic.courtes@laas.fr>
+
+	* posix.c (scm_ttyname): Check whether RESULT is NULL before
+	making a string from it (reported by Dan McMahill).  Don't call
+	`scm_from_locale_string ()' before the mutex is released.
+
+2007-05-26  Ludovic Courtès  <ludo@chbouib.org>
+
+	* eval.c (scm_m_define): Updated comment.  Changed order for value
+	evaluation and `scm_sym2var ()' call, which is perfectly valid per
+	R5RS.  This reverts the change dated 2004-04-22 by Dirk Herrmann.
+
+2007-05-05  Ludovic Courtès  <ludo@chbouib.org>
+
+	Implemented lazy duplicate binding handling.
+
+	* modules.c (scm_export): Renamed to...
+	(scm_module_export): This.  Now public.
+	(module_variable): Removed.
+	(default_duplicate_binding_procedures_var): New variable.
+	(default_duplicate_binding_handlers, resolve_duplicate_binding,
+	module_imported_variable, scm_module_local_variable,
+	scm_module_variable): New functions.
+	(scm_module_import_interface): Rewritten.
+	(scm_module_reverse_lookup): Exported as a Scheme function.
+	* modules.h (scm_module_index_duplicate_handlers,
+	scm_module_index_import_obarray): New macros.
+	(scm_module_variable, scm_module_local_variable,
+	scm_module_export): New declarations.
+
+2007-04-17  Ludovic Courtès  <ludovic.courtes@laas.fr>
+
+	* numbers.c: Commented out trailing `HAVE_COMPLEX_DOUBLE' after
+	`#endif'.  Use `#ifndef HAVE_XXX' rather than `#if !HAVE_XXX'.
+
+2007-04-09  Han-Wen Nienhuys  <hanwen@lilypond.org>
+
+	* numbers.c (carg): provide carg, cexp, clog in case they are
+	missing.
+
+2007-03-12  Ludovic Courtès  <ludovic.courtes@laas.fr>
+
+	* i18n.c (scm_nl_langinfo): `#ifdef'd uses of `GROUPING',
+	`FRAC_DIGITS', etc., which are GNU extensions.  Reported by
+	Steven Wu.
+
+2007-03-08  Kevin Ryde  <user42@zip.com.au>
+
+	* struct.c, struct.h (scm_make_vtable): New function, providing
+	`make-vtable'.
+	* stacks.c (scm_init_stacks): Use it.
+
+2007-03-06  Kevin Ryde  <user42@zip.com.au>
+
+	* struct.c (scm_make_struct): Check for R,W,O at end of layout when
+	allocating a tail array.  If there's no such then those tail fields
+	are uninitialized and garbage SCMs there can cause a segv if printed
+	(after fetching with struct-ref).
+
+2007-02-22  Kevin Ryde  <user42@zip.com.au>
+
+	* scmsigs.c (scm_sleep): In docstring, cross refence usleep.
+	(scm_usleep): Update docstring per manual, cross reference sleep.
+
+	* struct.c (scm_make_struct): Move SCM_CRITICAL_SECTION_END up so that
+	scm_struct_init is not within that section.  scm_struct_init can
+	thrown an error, which within a critical section results in an
+	abort().
+
+2007-02-19  Neil Jerram  <neil@ossau.uklinux.net>
+
+	* Makefile.am (noinst_HEADERS): Add private-options.h, so that it
+	is included in the distribution.
+	(noinst_HEADERS): And the same for eval.i.c.
+
+2007-01-31  Ludovic Courtès  <ludovic.courtes@laas.fr>
+
+	* i18n.c: Include "libguile/threads.h" and "libguile/posix.h"
+	unconditionally.  Include <langinfo.h> and <nl_types.h> when
+	available.
+	(SCM_I18N_STRINGIFY, SCM_LOCALE_CATEGORY_MASK,
+	SCM_LIST_OR_INTEGER_P): New macros.
+	(LC_*_MASK): When `USE_GNU_LOCALE_API' is undefined, define them
+	as powers of two instead of `(1 << LC_*)'.
+	(scm_i_locale_free): New function/macro.
+	(scm_global_locale): New global variable.
+	(smob_locale_free): Use `scm_i_locale_free ()'.
+	(smob_locale_mark): Check whether the SMOB is `%global-locale'.
+	(get_current_locale_settings): Return `EINVAL' instead of `errno'
+	when `setlocale' fails.
+	(restore_locale_settings): Likewise.
+	(install_locale_categories): Likewise.
+	(install_locale): Likewise.  Stop the locale stack traversal when
+	all categories have been handled.
+	(get_current_locale, category_to_category_mask,
+	category_list_to_category_mask): New function.
+	(scm_make_locale): Use them.  Accept both lists of `LC_*' values
+	and single `LC_*' values as the first argument.  Handle the case
+	where BASE_LOCALE is `%global-locale'.  When `USE_GNU_LOCALE_API',
+	duplicate C_BASE_LOCALE before using it.
+	(scm_nl_langinfo, define_langinfo_items): New functions.
+	(scm_init_i18n): When `HAVE_NL_LANGINFO', add feature
+	`nl-langinfo' and invoke `define_langinfo_items ()'.
+	* i18n.h (scm_global_locale, scm_nl_langinfo): New declarations.
+	* posix.c: Include <xlocale.h> when available.
+	(scm_i_locale_mutex): Always define it.  Statically initialized.
+	(scm_set_locale): Invoke `scm_i_to_lc_category ()' before
+	acquiring the locale mutex.
+	(scm_init_posix): No longer initialize SCM_I_LOCALE_MUTEX here.
+
+2007-01-27  Kevin Ryde  <user42@zip.com.au>
+
+	* ports.c (scm_port_line, scm_set_port_line_x), read.c
+	(scm_i_input_error, scm_lreadr, scm_lreadrecparen): Corrections to
+	port line number type, should be "long" not "int", as per line_number
+	field of scm_t_port.  (Makes a difference only on 64-bit systems, and
+	only then for a linenum above 2Gig.)
+
+2007-01-25  Han-Wen Nienhuys  <hanwen@lilypond.org>
+
+	* vector.c: remove comment as per kryde's request.
+
+2007-01-25  Kevin Ryde  <user42@zip.com.au>
+
+	* sort.c (scm_stable_sort): Return empty list for input empty list, as
+	done in guile 1.6 and as always done by plain `sort'.  Was falling
+	through to SCM_WRONG_TYPE_ARG.  Reported by Ales Hvezda.
+
+2007-01-22  Han-Wen Nienhuys  <hanwen@lilypond.org>
+
+	* vectors.c (s_scm_vector_move_right_x): complain about naming.
+
+	* srcprop.c: regularize comments.
+
+	* eval.c: remove superfluous ifndef DEVAL.
+
+	* private-options.h: idem.
+
+	* eval.i.c: copyright nitpicking.
+
+	* eval.c: distangle. move duplicate code to eval.i.c and include
+	twice.
+
+	* eval.i.c: new file.
+
+	* backtrace.c, debug.c, debug.h, deprecation.c, eq.c, eval.c
+	eval.h, gsubr.c, init.c, macros.c, print.c, print.h, read.c,
+	read.h, stacks.c, symbols.c, throw.c: use private-options.h
+
+	* private-options.h: new file: contain hardcoded option
+	definitions.
+
+	* private-gc.h: add FSF header.
+
+2007-01-19  Han-Wen Nienhuys  <hanwen@lilypond.org>
+
+	* debug.h (SCM_RESET_DEBUG_MODE): switch to debugging if
+	memoize-symbol is set.
+
+	* eval.h (SCM_MEMOIZE_HDLR): add macros for memoize symbol trap.
+
+	* eval.c (CEVAL): add memoize_symbol trap.
+
+	* options.c (scm_options_try): new function. This allows error
+	reporting before changing options in a critical section.
+
+	* srcprop.c: use double cell for storing source-properties.  Put
+	filename in the plist, and share between srcprops if possible.
+	Remove specialized storage.
+
+	* srcprop.h: remove macros without SCM_ prefix from
+	interface. Remove specialized storage/type definitions.
+
+	* read.c: idem.
+
+	* print.c: idem.
+
+	* eval.c: terminate option lists with 0.
+
+	* options.c: remove n (for length) from scm_option_X
+	functions. Detect option list length by looking for NULL name.
+
+2007-01-19  Ludovic Courtès  <ludovic.courtes@laas.fr>
+
+	* struct.c (scm_i_struct_equalp): Skip comparison if both FIELD1
+	is equal to S1 and FIELD2 is equal to S2.  This avoids infinite
+	recursion when comparing `s' fields, as the REQUIRED_VTABLE_FIELDS
+	added by `make-vtable-vtable'.  Reported by Marco Maggi.
+
+2007-01-18  Han-Wen Nienhuys  <hanwen@lilypond.org>
+
+	* throw.c (scm_ithrow): more refined error message: print symbols
+	too.
+
+2007-01-16  Kevin Ryde  <user42@zip.com.au>
+
+	* feature.c, feature.h (scm_set_program_arguments_scm): New function,
+	implementing `set-program-arguments'.
+
+	* filesys.c (scm_init_filesys): Use scm_from_int rather than
+	scm_from_long for O_RDONLY, O_WRONLY, O_RDWR, O_CREAT, O_EXCL,
+	O_NOCTTY, O_TRUNC, O_APPEND, O_NONBLOCK, O_NDELAY, O_SYNC and
+	O_LARGEFILE.  These are all int not long, per arg to open().
+	(scm_init_filesys): Use scm_from_int rather than scm_from_long for
+	F_DUPFD, F_GETFD, F_SETFD, F_GETFL, F_SETFL, F_GETOWN, F_SETOWN, these
+	are all ints (per command arg to fcntl).  Likewise FD_CLOEXEC which is
+	an int arg to fcntl.
+
+	* posix.c (scm_putenv): Correction to "len" variable, was defined only
+	for __MINGW32__ but used under any !HAVE_UNSETENV (such as solaris).
+	Move it to where it's used.  Reported by Hugh Sasse.
+
+	* regex-posix.c (scm_regexp_exec): Remove SCM_CRITICAL_SECTION_START
+	and SCM_CRITICAL_SECTION_END, believe not needed.  Their placement
+	meant #\nul in the input (detected by scm_to_locale_string) and a bad
+	flags arg (detected by scm_to_int) would throw from a critical
+	section, causing an abort().
+
+	* regex-posix.c (scm_init_regex_posix): Use scm_from_int for
+	REG_BASIC, REG_EXTENDED, REG_ICASE, REG_NEWLINE, REG_NOTBOL,
+	REG_NOTEOL; they're all ints not longs (per args to regcomp and
+	regexec).
+
+2007-01-10  Han-Wen Nienhuys  <hanwen@lilypond.org>
+
+	* throw.c (scm_ithrow): print out key symbol and string arguments
+	when error happens inside a critical section, and document why.
+
+2007-01-06  Han-Wen Nienhuys  <hanwen@lilypond.org>
+
+	* read.c (s_scm_read_hash_extend): document #f argument to
+	read-hash-extend.
+
+2007-01-04  Kevin Ryde  <user42@zip.com.au>
+
+	* deprecated.h (scm_create_hook), version.h.in (scm_major_version,
+	scm_minor_version, scm_micro_version, scm_effective_version,
+	scm_version, scm_init_version): Use SCM_API instead of just extern,
+	for the benefit of mingw.  Reported by Cesar Strauss.
+
+2007-01-03  Han-Wen Nienhuys  <hanwen@lilypond.org>
+
+	* gc.c (s_scm_gc_stats): return an entry for total-cells-allocated
+	too.
+	(gc_update_stats): update scm_gc_cells_allocated_acc too.
+
+2006-12-27  Kevin Ryde  <user42@zip.com.au>
+
+	* threads.c (get_thread_stack_base): In mingw with pthreads we can use
+	the basic scm_get_stack_base.  As advised by Nils Durner.
+
+	* threads.c (get_thread_stack_base): Add a version using
+	pthread_get_stackaddr_np (when available), for the benefit of MacOS.
+	As advised by Heikki Lindholm.
+
+	* scmsigs.c (signal_delivery_thread): Restrict scm_i_pthread_sigmask
+	to HAVE_PTHREAD_SIGMASK, it doesn't exist on mingw.  Reported by Nils
+	Durner.
+
+2006-12-24  Kevin Ryde  <user42@zip.com.au>
+
+	* posix.c (scm_kill): When only raise() is available, throw an ENOSYS
+	error if pid is not our own process, instead of silently doing nothing.
+
+	* print.c (scm_write, scm_display, scm_write_char): Disable port close
+	on EPIPE.  This was previously disabled but introduction of HAVE_PIPE
+	check in configure.in unintentionally enabled it.  Believe that
+	testing errno after scm_prin1 or scm_putc is bogus, a long ago error
+	can leave errno in that state.  popen.test "no duplicates" output test
+	provoked that.
+
+2006-12-23  Han-Wen Nienhuys  <hanwen@lilypond.org>
+
+	* numbers.c (scm_i_fraction_reduce): move logic into
+	scm_i_make_ratio(), so fractions are only read.
+	scm_i_fraction_reduce() modifies a fraction when reading it.  A
+	race condition might lead to fractions being corrupted by reading
+	them concurrently.
+
+	Also, the REDUCED bit alters the SCM_CELL_TYPE(), making
+	comparisons between reduced and unreduced fractions go wrong.
+
+	* numbers.h: remove SCM_FRACTION_SET_NUMERATOR,
+	SCM_FRACTION_SET_DENOMINATOR, SCM_FRACTION_REDUCED_BIT,
+	SCM_FRACTION_REDUCED_SET, SCM_FRACTION_REDUCED_CLEAR,
+	SCM_FRACTION_REDUCED.
+
+2006-12-16  Kevin Ryde  <user42@zip.com.au>
+
+	* scmsigs.c (scm_raise): Use raise() rather than kill(), as this is
+	more direct for a procedure called raise.
+	(kill): Remove mingw fake fallback.
+
+2006-12-15  Kevin Ryde  <user42@zip.com.au>
+
+	* scmsigs.c: Conditionalize process.h, add io.h believe needed for
+	_pipe on mingw.
+
+2006-12-14  Kevin Ryde  <user42@zip.com.au>
+
+	* threads.c (thread_print): Cope with the case where pthread_t is a
+	struct, as found on mingw.  Can't just cast to size_t for printing.
+	Reported by Nils Durner.
+
+	* scmsigs.c: Add <fcntl.h> and <process.h> needed by mingw.  Copy the
+	fallback pipe() using _pipe() from posix.c.  Reported by Nils Durner.
+
+2006-12-13  Kevin Ryde  <user42@zip.com.au>
+
+	* eval.c (scm_m_define): Set 'name procedure property on any
+	scm_procedure_p, not just SCM_CLOSUREP.  In particular this picks up
+	procedures with setters as used in srfi-17.
+
+	* posix.c (scm_crypt): Check for NULL return from crypt(), which the
+	linux man page says is a possibility.
+
+2006-12-12  Ludovic Courtès  <ludovic.courtes@laas.fr>
+
+	* libguile/unif.c (read_decimal_integer): Let RESP be SIGN * RES
+	instead of RES (reported by Szavai Gyula).  This allows the use of
+	negative lower bounds.
+	(scm_i_read_array): Make sure LEN is non-negative (reported by
+	Szavai Gyula).
+
+	(scm_array_in_bounds_p): Iterate over S instead of always
+	comparing indices with the bounds of S[0].  This fixes
+	`array-in-bounds?' for arrays with a rank greater than one and
+	with different lower bounds for each dimension.
+
+2006-12-05  Kevin Ryde  <user42@zip.com.au>
+
+	* numbers.c (scm_product): For flonum*inum and complex*inum, return
+	exact 0 if inum==0.  Already done for inum*flonum and inum*complex,
+	and as per R5RS section "Exactness".
+
+2006-12-03  Kevin Ryde  <user42@zip.com.au>
+
+	* Makefile.am (.c.doc): Remove the "test -n" apparently attempting to
+	allow $AWK from the environment to override.  It had syntax gremlins,
+	and the presence of a $(AWK) variable set by AC_PROG_AWK in the
+	Makefile stopped it having any effect.  Use just $(AWK), which can be

+2006-11-29  Ludovic Courtès  <ludovic.courtes@laas.fr>
+
+	* libguile/vectors.c (scm_vector_to_list): Fixed list
+	construction: elements were not copied when INC is zero (see
+	"shared array" example in `vectors.test').  Reported by
+	Szavai Gyula.
+
+2006-11-18  Ludovic Courtès  <ludovic.courtes@laas.fr>
+
+	* Makefile.am (lib_LTLIBRARIES): Added `libguile-i18n-v-XX.la'.

+	(EXTRA_libguile_la_SOURCES): Added `locale-categories.h'.
+	(modinclude_HEADERS): Added `gettext.h'.
+	(EXTRA_DIST): Added `libgettext.h'.
+
+	* gettext.h: Renamed to...
+	* libgettext.h: New file.
+
+	* i18n.c: Renamed to...
+	* gettext.c: New file.
+

+	(scm_i_init_guile): Invoke `scm_init_gettext ()' instead of
+	`scm_init_i18n ()'.
+
+	* posix.c: Include "libguile/gettext.h" instead of

+2006-11-17  Neil Jerram  <neil@ossau.uklinux.net>
+
+	* script.c (scm_shell_usage): Note need for subscription to bug-guile@gnu.org.
+
+2006-11-08  Ludovic Courtès  <ludovic.courtes@laas.fr>
+
+	* libguile/gc-freelist.c (scm_i_adjust_min_yield): Take two
+	"sweep_stats" arguments; use them instead of accessing the global

+	before each iteration of the loop.

+	Declaration removed.
+	(scm_t_contregs): New "fresh" field.
+
+	* continuations.c (ia64_getcontext): Removed.
+	(scm_make_continuation): Use continuation fresh field instead of

+
+2006-09-28  Kevin Ryde  <user42@zip.com.au>
+
+	* fports.c, ports.c (ftruncate): Use "HAVE_CHSIZE && ! HAVE_FTRUNCATE"
+	for chsize fallback, instead of hard-coding mingw.  Mingw in fact
+	supplies ftruncate itself these days.

+	* ports.c (fcntl.h): Can include this unconditionally, no need for
+	__MINGW32__.
+
+	* ports.c (truncate): Conditionalize on "HAVE_FTRUNCATE && !
+	HAVE_TRUNCATE" so as not to hard-code mingw.  Use "const char *" and

+	error on final close.
+
+2006-09-27  Kevin Ryde  <user42@zip.com.au>
+
+	* numbers.c (scm_log10): Check HAVE_CLOG10, clog10() is not available
+	in mingw.
+
+	* posix.c (scm_execl, scm_execlp, scm_execle): Cast "const char *
+	const *" for mingw to suppress warnings from gcc (which are errors
+	under the configure default -Werror).  Reported by Nils Durner.
+
+2006-09-26  Kevin Ryde  <user42@zip.com.au>
+
+	* _scm.h (scm_to_off64_t, scm_from_off64_t): New macros.

+	New, set from configure.
+	* gen-scmconfig.c (SCM_NEED_BRACES_ON_PTHREAD_ONCE_INIT): New output

+	* pthread-threads.h (SCM_I_PTHREAD_ONCE_INIT): Use
+	SCM_NEED_BRACES_ON_PTHREAD_ONCE_INIT to cope with Solaris.
+	Reported by Claes Wallin.
+
+2006-08-11  Neil Jerram  <neil@ossau.uklinux.net>
+
+	* stacks.c (scm_last_stack_frame): Correct docstring (returns a
+	frame, not a stack).
+
+2006-07-25  Kevin Ryde  <user42@zip.com.au>
+
+	* threads.c (get_thread_stack_base): Restrict HAVE_PTHREAD_GETATTR_NP
+	on pthreads version, since pthread_getattr_np not available on solaris

+
+2006-07-24  Kevin Ryde  <user42@zip.com.au>
+
+	* filesys.c (dirfd): Test with #ifndef rather than HAVE_DIRFD, since
+	it's a macro on MacOS X.  Reported by Claes Wallin.
+
+	* posix.c (sethostname): Give prototype if not HAVE_DECL_SETHOSTNAME,
+	for the benefit of Solaris 10.  Reported by Claes Wallin.
+
+	* socket.c (scm_htonl, scm_ntohl): Use scm_to_uint32 rather than
+	NUM2ULONG, to enforce 32-bit range check on systems with 64-bit long.
+
+2006-07-21  Kevin Ryde  <user42@zip.com.au>
+
+	* eval.c, filesys.c (alloca): Update <alloca.h> etc blob, per current
+	autoconf recommendation.  Should fix Solaris 10 reported by Claes
+	Wallin.
+
+	* threads.c: Include <string.h>, needed for memset() which is used by
+	FD_ZERO() on Solaris 10.  Reported by Claes Wallin.
+
+2006-07-18  Rob Browning  <rlb@defaultvalue.org>
+
+	* continuations.c: Add __attribute__ ((returns_twice)) to the
+	ia64_getcontext prototype so that gcc will make the right
+	arrangements and avoid an illegal instruction during
+	call-with-current-continuation.
+
+2006-07-12  Ludovic Courtès <ludovic.courtes@laas.fr>
+
+	* numbers.c (guile_ieee_init): Use regular ANSI C casts rather

+
+2006-07-08  Kevin Ryde  <user42@zip.com.au>
+
+	* environments.c (core_environments_unobserve): Use if/else rather
+	than ?: for "SET" bits, avoiding complaints from AIX xlc compiler
+	about them not being rvalues.  Reported by Mike Gran.
+
+	* Makefile.am (version.h): Don't use $< in an explicit rule, it's not
+	portable and in particular fails on OpenBSD and AIX (see autoconf
+	manual too).  Reported by Mike Gran.
+
+2006-06-25  Kevin Ryde  <user42@zip.com.au>
+
+	* stime.c (bdtime2c): tm_gmtoff is seconds East, so take negative of
+	tm:gmtoff which is seconds West.  Reported by Aaron VanDevender.
+	(bdtime2c): Test HAVE_STRUCT_TM_TM_GMTOFF for tm_gmtoff, rather than
+	HAVE_TM_ZONE.

+
+2006-06-06  Kevin Ryde  <user42@zip.com.au>
+
+	* Makefile.am (BUILT_SOURCES): Remove guile.texi, only used by
+	maintainers (with doc/maint/docstring.el).  Fixes parallel "make -j2"
+	reported by Mattias Holm.
+
+2006-06-03  Kevin Ryde  <user42@zip.com.au>
+
+	* read.c (s_vector): Conditionalize on SCM_ENABLE_ELISP, to avoid
+	unused variable warning when elisp disabled.  Reported by Ryan
+	VanderBijl.
+
+	* throw.c (scm_handle_by_message): Add dummy return value to avoid
+	compiler warning on cygwin.  Reported by Ryan VanderBijl.
+
+	* Makefile.am (EXTRA_DOT_X_FILES): Typo in dependency rule, was a
+	duplicate of EXTRA_DOT_DOC_FILES.
+	(DOT_X_FILES, EXTRA_DOT_X_FILES, DOT_DOC_FILES, EXTRA_DOT_DOC_FILES):
+	Add scmconfig.h to dependencies, since these all run cpp.  Helps a
+	parallel "make -j2".  Reported by Mattias Holm.
+
+2006-05-30  Kevin Ryde  <user42@zip.com.au>
+
+	* ports.c, ports.h (scm_set_port_mark, scm_set_port_free,

+	scm_set_port_end_input, scm_set_port_close, scm_set_port_seek,
+	scm_set_port_truncate, scm_set_port_input_waiting): Use scm_t_bits for
+	port type descriptor, same as scm_make_port_type return value.
+
+2006-05-30  Marius Vollmer  <mvo@zagadka.de>
+
+	* eq.c (scm_equal_p): Use scm_array_equal_p explicitely when one
+	of the arguments is a array.  This allows vectors to be equal to
+	one-dimensional arrays.
+
+2006-05-29  Marius Vollmer  <mvo@zagadka.de>
+
+	* throw.c (scm_ithrow): When looking for the jmpbuf, first test

+	as defined(FIONREAD), since mingw has FIONREAD but not ioctl().
+	Reported by "The Senator".
+	For select and ioctl, move fdes into those conditionals, to avoid
+	unused variable warning when neither of those used.
+
+2006-05-23  Kevin Ryde  <user42@zip.com.au>
+
+	* fports.c: Remove "fwrite" declaration under "! HAVE_UNISTD_H".

+2006-05-20  Kevin Ryde  <user42@zip.com.au>
+
+	* filesys.c (scm_stat2scm): Test #ifdef S_ISLNK directly, rather than
+	HAVE_S_ISLNK from configure (it was only a #ifdef test anyway).

+
+	* numbers.c (scm_i_divide): For big/big wanting inexact, use mpq_get_d
+	rather than converting to doubles, to avoid inf or nan when the inputs
+	are too big for a double but the quotient does fit.  This affects
+	conversions exact->inexact of big fractions.
+
+	* filesys.c (scm_open_fdes): Use open64.
+	(scm_init_filesys): Add O_LARGEFILE.
+
+	* ports.c (scm_seek): Use lseek64.

+
+2006-04-18  Rob Browning  <rlb@defaultvalue.org>

+
+2006-04-18  Kevin Ryde  <user42@zip.com.au>
+
+	* posix.c (scm_mkstemp): Update docstring from the manual, in

+	available.
+
+2006-04-06  Kevin Ryde  <user42@zip.com.au>
+
+	* fports.c (scm_setvbuf): Fix for not _IOLBF, clear SCM_BUFLINE
+	instead of toggling it.  Reported by Ludovic Courtès.
+
+2006-03-26  Marius Vollmer  <mvo@zagadka.de>
+
+	* threads.c (get_thread_stack_base): Use scm_get_stack_base
+	instead of accessing __libc_stack_end directly, and only do this
+	when pthread_attr_getstack is known not to work for the main
+	thread or when not using pthreads at all.
+
+	* gc_os_dep.c (scm_get_stack_base): Abort when the machine type is
+	unknown instead of returning NULL.
+
+2006-03-21  Ludovic Courtès  <ludovic.courtes@laas.fr>
+

+	oldra is not an array.  (Reported by Steve Juranich.)
+
+	* threads.c (do_unlock): Renamed from "unlock", which is defined

+2006-03-04  Kevin Ryde  <user42@zip.com.au>
+
+	* deprecated.c (scm_i_defer_ints_etc): Show SCM_DEFER_INTS in message,

+
+	* filesys.c (scm_readdir): Use fpathconf for the dirent size when

+
+        * gc-segment.c (scm_i_sweep_some_cards): Take a SWEEP_STATS
+        argument.  Don't refer to SCM_GC_CELLS_COLLECTED and
+        SCM_CELLS_ALLOCATED.  If SEG->FIRST_TIME, let CELLS_COLLECTED as zero.
+        Take into account SEG->SPAN when computing CELLS_SWEPT.
+        (scm_i_sweep_segment): Take one more argument, similarly.
+        (scm_i_sweep_all_segments): Likewise.
+        (scm_i_sweep_some_segments): Likewise.
+        (scm_i_adjust_min_yield): Change the way MIN_CELLS is computed: do not

+
+        * gc-freelist.c (scm_i_adjust_min_yield): Take one more
+        argument, an `scm_i_sweep_statistics' object.
+        Change the way DELTA is collected: don't take into account
+        SCM_GC_CELLS_COLLECTED_1, only SWEEP_STATS.COLLECTED.
+
+        * gc-malloc.c (scm_realloc): Pass an extra argument

+
+        * strings.c (scm_i_take_stringbufn): Register LEN+1 bytes instead of

+	which results in an underflow of SCM_MALLOCATED in
+	`decrease_mtrigger()'.
+
+        * gc-malloc.c (decrease_mtrigger): Make sure SIZE is lower than or

+2006-02-13  Marius Vollmer  <mvo@zagadka.de>
+
+	* eval.c (scm_eval_body): Use scm_i_dynwind_pthread_mutex_lock

+2006-02-12  Marius Vollmer  <mvo@zagadka.de>
+
+	* unif.c (scm_dimensions_to_uniform_array): Use the prototype for

+	turn #\nul into 0 since s8 arrays (signified by a #\nul prototype)
+	can not store characters.
+
+2006-02-09  Neil Jerram  <neil@ossau.uklinux.net>

+	(struct pre_unwind_data): New, replaces struct lazy_catch.
+	(scm_c_catch): New, replaces scm_internal_catch as the primary
+	catch API for C code; adds pre-unwind handler support.
+	(scm_internal_catch): Now just a wrapper for scm_c_catch, for back
+	compatibility.
+	(tc16_pre_unwind_data, pre_unwind_data_print,

+	(scm_lazy_catch): Update comment to say that the handler can
+	return, and what happens if it does.
+	(toggle_pre_unwind_running): New.
+	(scm_ithrow): When identifying the throw target, take running
+	flags into account.  In general, change naming of things from
+	"lazy_catch" to "pre_unwind".  When throwing to a throw handler,
+	don't unwind the dynamic context first.  Add dynwind framing to
+	manage the running flag of a throw handler.  If a lazy catch or
+	throw handler returns, rethrow the same exception again.  Add
+	pre-unwind support to the normal catch case (SCM_JMPBUFP).
+
+	* root.c (scm_internal_cwdr): Add NULL args to
+	scm_i_with_continuation_barrier call.
+

+2006-02-03  Kevin Ryde  <user42@zip.com.au>
+
+	* list.c, list.h (scm_list): Restore this function for use from C.

+
+2005-12-07  Marius Vollmer  <mvo@zagadka.de>
+
+	Reported by Bruce Korb:

+	(scm_boot_guile): Expect scm_with_guile to return and call exit
+	here, passing it an appropriate exit code.
+
+	From Andy Wingo:

+2005-12-06  Marius Vollmer  <mvo@zagadka.de>
+
+	* srfi-4.h, srfi-4.c, srfi-4.i.c (take_uvec): Make BASE pointer

+	scm_malloc returning NULL, it never does that.
+	* putenv.c (putenv): Likewise.
+
+	* socket.c (scm_fill_sockaddr): Remove SCM_C_INLINE_KEYWORD, this is

+
+2005-11-17  Ludovic Courtès  <ludovic.courtes@laas.fr>
+
+	* print.c (EXIT_NESTED_DATA): Before popping from the stack, reset

+
+	New marking algorithm for weak hashtables that fixes the problem
+	that references from the non-weak value to the associated weak
+	key (for example) would prevent the entry from ever being dropped.
+
+	Guardians have been changed back to their original semantics and
+	are no longer greedy and no longer drop cycles.
+
+	* gc-mark.c (scm_mark_all): Do not rely on hooks to run the weak
+	hashtable and guardian machinery but call the relevant functions
+	directly.
+
+	* guardians.h, guardians.c, deprecated.h,
+	deprecated.c (scm_destroy_guardian_x, scm_guardian_greedy_p,

+	Reported by Ken Raeburn.
+
+	* gc-card.c (scm_dbg_gc_get_bvec): Change return from long* to

+
+2005-07-10  Kevin Ryde  <user42@zip.com.au>
+

+
+	* srfi-13.c (scm_string_filter, scm_string_delete): Partial revert
+	last change, use plain copy-on-write substrings, the individual

+	introduction does).
+
+	* strings.c (scm_take_locale_stringn): Use realloc to make room for

+	* ramap.c (scm_array_index_map_x): First test for real arrays,
+	then check for generalized vectors.  This ensures that the
+	generalized vector case need only work with zero-origin ranges.
+	(scm_ra_eqp, scm_ra_compare): Use the new array handle functions
+	to access the target array, making these functions work with all
+	kinds of arrays, not just bit arrays.
+
+	* gh.h, gh_data.c, gh_eval.c, gh_funcs.c, gh_init.c, gh_io.c,
+	gh_list.c, gh_predicates.c: Deprecated everything.
+
+	* environments.c (environment_default_folder,
+	environment_default_observer): Do not use gh_call3, gh_call1.
+
+2005-06-10  Han-Wen Nienhuys  <hanwen@xs4all.nl>
+
+	* modules.c (s_scm_eval_closure_module): new function. Return the
+	module inside an eval-closure.
+
+	* gc.c (scm_init_storage): make scm_stand_in_procs a weak_key hash
+	table. This means that procedure properties are GC'd if the
+	procedure dies.
+
+2005-06-11  Kevin Ryde  <user42@zip.com.au>
+
+	* srfi-13.c (scm_string_filter, scm_string_delete): For char and
+	charset cases, count chars kept and build a string in a second pass,
+	rather than using a cons cell for every char kept.  Use a shared
+	substring when nothing removed (such sharing is allowed by the srfi).
+
+2005-06-09  Han-Wen Nienhuys  <hanwen@xs4all.nl>
+
+	* gc.c (tag_table_to_type_alist): convert tag number to "tag %d"
+	string, so live object stats can be sorted with string<?.
+
+2005-06-06  Marius Vollmer  <mvo@zagadka.de>
+
+	* print.c (iprin1): When writing a string, collect all characters
+	that can be printed directly into one call to scm_lfwrite.
+	Previously, every character was output with its own call to
+	write(2) on unbuffered ports.
+
+	* eval.c (scm_eval_options_interface): Use
+	scm_frame_critical_section instead of SCM_CRITICAL_SECTION_START
+	and SCM_CRITICAL_SECTION_END.
+
+	* unif.c (scm_array_in_bounds_p): First test for real arrays, then
+	check for generalized vectors.  This ensures that the generalized
+	vector case need only work with zero-origin ranges.
+
+2005-06-06  Kevin Ryde  <user42@zip.com.au>
+
+	* srfi-13.c (scm_string_split): Compare char/char in scan.  Mixing an
+	unsigned int SCM_CHAR and a char string meant an 8-bit char was never
+	matched.
+
+2005-06-05  Marius Vollmer  <mvo@zagadka.de>
+
+	* eval.c: Added comment on how to make case 1.1 of
+	r5rs_pitfall.test succeed.
+
+	From Jan Nieuwenhuizen <janneke@gnu.org>. Thanks!
+
+ 	* hashtab.h: Bugfix: use SCM_API (WAS: extern).
+
+ 	* socket.c: Remove obsolete comment about socklen_t.

+
+ 	* stime.c (scm_strftime)[!HAVE_TM_ZONE]: Use

+	from Jan's patch.)
+
+2005-05-22  Marius Vollmer  <mvo@zagadka.de>
+
+	* unif.c (scm_make_shared_array): Add old base to new base since
+	scm_array_handle_pos does not include the base.
+	(scm_aind): Likewise.
+
+	* ports.c (scm_putc, scm_puts): Assert that the port argument is a
+	output port.
+
+2005-05-12  Neil Jerram  <neil@ossau.uklinux.net>
+
+	Mac OS X compile warning fixes, reported by Richard Todd.

+
+	* srfi-13.c (string_titlecase_x): Add unsigned char cast.
+
+	* rdelim.c (scm_read_line): Initialize slen.
+
+	* load.c (scm_search_path): Remove weird >=1, and add
+	parentheses to clarify conditions.
+
+	* hash.c (scm_hasher): Add const unsigned char cast.
+
+	* gh_data.c (gh_chars2byvect): Add scm_t_int8 cast.
+
+2005-05-11  Neil Jerram  <neil@ossau.uklinux.net>

+	* threads.c (s_scm_lock_mutex): Don't declare msg in middle of
+	code.
+
+	* gc.c (s_scm_gc_live_object_stats): Don't declare alist in middle
+	of code.
+
+	* gc-card.c (scm_i_card_statistics): Don't declare tag in middle
+	of code.
+	(scm_i_card_statistics): Add block for declarations of tag_as_scm
+	and current.
+
+2005-05-10  Neil Jerram  <neil@ossau.uklinux.net>
+
+	* scmsigs.c (signal_delivery_thread): Return a value, to avoid

+
+	* list.h: remove scm_list()

+	* fluids.c (DYNAMIC_STATE_NEXT_LOC): new macro for use with
+	SCM_DEBUG_CELL_ACCESSES
+	(FLUID_NEXT_LOC): idem.
+
+2005-04-30  Kevin Ryde  <user42@zip.com.au>
+
+	* numbers.c (scm_divide): Correction to 1/complex and <any>/complex,
+	need to test abs(re)<abs(im) for choice of cases, otherwise divide by
+	zero when re==0 and im<0.  Reported by Jean Crepeau.
+
+2005-04-25  Kevin Ryde  <user42@zip.com.au>
+
+	* ramap.c (scm_array_map_x): Allow no source args, add num args checks
+	to subr_1, subr_2, subr_2o and dsubr cases.  No source args only has a
+	few sensible uses (like filling with a random number generator say),
+	but has been allowed in the past and so should be kept.
+
+2005-04-23  Kevin Ryde  <user42@zip.com.au>
+
+	* hashtab.c (scm_hashx_remove_x): Need to pass "closure" to
+	scm_hash_fn_remove_x.
+
+	* list.c (scm_cons_star): Don't modify the rest list, it belongs to
+	the caller when cons* is reached through apply.
+
+	* list.c (list): Use scm_list_copy, so as to produce a fresh list when
+	list is called using apply, under the debugging evaluator.
+	(scm_list): Remove.
+
+	* list.c, list.h (scm_make_list): New code, moving make-list from
+	boot-9.scm.
+
+2005-04-14  Kevin Ryde  <user42@zip.com.au>
+
+	* numbers.c, numbers.h (scm_oneplus, scm_oneminus): New functions,
+	converted from scheme code in boot-9.scm.
+
+2005-04-11  Kevin Ryde  <user42@zip.com.au>
+
+	* srfi-13.c (scm_string_concatenate, scm_string_concatenate_shared):
+	Validate list argument, scm_string_append and scm_string_append_shared
+	don't do that to their rest argument (in a normal build).
+
+2005-04-04  Marius Vollmer  <marius.vollmer@uni-dortmund.de>
+
+	* hashtab.h, hashtab.c (scm_t_hashtable): Removed 'closure' field.  The
+	closure can not be stored since it is no longer valid at GC time.
+	(make_hash_table): Initialize 'hash_fn' field.
+	(scm_i_rehash): Only store hash_fn in hash table when closre is
+	NULL.
+	(rehash_after_gc): Only call scm_i_rehash when 'hash_fn' is
+	non-NULL.  Always use a NULL closure.
+	(scm_hash_fn_create_handle_x): Also rehash when table contains too
+	few entries.
+
+2005-03-29  Marius Vollmer  <marius.vollmer@uni-dortmund.de>
+
+	* hashtab.h, hashtab.c (scm_hash_fx_remove_x): Removed delete_fn
+	argument; always use scm_delq_x.  The delete_fn function works on
+	the handle, not the key, and it therefore makes no sense to make
+	it configurable.  Changed all callers.
+	(scm_hashx_remove_x): Likewise.  Also, exported to Scheme.
+	(scm_hash_clear): Accept plain vectors as hashtables.
+	(scm_delx_x): Removed.
+
+2005-03-28  Han-Wen Nienhuys  <hanwen@xs4all.nl>

+
+2005-03-24  Mikael Djurfeldt  <djurfeldt@nada.kth.se>
+
+	* async.h (scm_mask_ints): Removed left over reference to

+	* debug.c (scm_make_memoized): Remove unnecessary critical
+	section, and simplify by using SCM_RETURN_NEWSMOB.
+
+2005-03-20  Mikael Djurfeldt  <djurfeldt@nada.kth.se>
+
+	* strings.h (SCM_STRING_UCHARS): Added missing argument.
+
+2005-03-18  Kevin Ryde  <user42@zip.com.au>
+
+	* arbiters.c (FETCH_STORE) [generic C]: Should be
+	scm_i_scm_pthread_mutex_lock/unlock now.  Reported by Ludovic Courtès.
+
+2005-03-13  Kevin Ryde  <user42@zip.com.au>
+
+	* numbers.c, numbers.h (scm_i_clonebig): Remove static, so can use in
+	srfi-60.
+
+	* numbers.c (scm_logior): Must scm_i_normbig results as per scm_logand,
+	because OR-ing bits into a negative can reduce the value to an inum.
+
+	* numbers.c (scm_num_eq_p): On 64-bit systems, be careful about
+	casting inum to double since that can lose precision.
+
+2005-03-10  Marius Vollmer  <marius.vollmer@uni-dortmund.de>
+
+	* threads.h, threads.c (scm_i_thread): Added gc_running_p field.
+	(guilify_self_1): Initialize it.
+
+	* gc.h, gc.c (SCM_FREECELL_P): Removed for good.
+	(scm_block_gc, scm_gc_heap_lock): Removed.  Removed all uses.
+	(scm_gc_running_p): Now a macro that refers to the scm_i_thread
+	field.
+	(scm_i_sweep_mutex): Now a non-recursive mutex.  GC can not happen
+	recursively.
+	(scm_igc, scm_i_gc): Renamed former to latter.  Changed all uses.
+	Do not lock scm_i_sweep_mutex, which is now non-recursive, or set
+	scm_gc_running_p.  Do not run the scm_after_gc_c_hook.
+	(scm_gc): Lock scm_i_sweep_mutex, set scm_gc_running_p and run the
+	scm_after_gc_c_hook here.
+	(scm_gc_for_new_cell): Set scm_gc_running_p here and run the
+	scm_after_gc_c_hook when a full GC has in fact been performed.
+	(scm_i_expensive_validation_check): Call scm_gc, not scm_i_gc.
+
+	* gc-segment.c (scm_i_get_new_heap_segment): Do not check
+	scm_gc_heap_lock.
+
+	* gc-malloc.c (scm_realloc, increase_mtrigger): Set
+	scm_gc_running_p while the scm_i_sweep_mutex is locked.
+
+	* inline.h (scm_cell, scm_double_cell): Do not check
+	scm_gc_running_p, allocation during sweeping is OK.
+
+	* gdbint.c (SCM_BEGIN_FOREIGN_BLOCK, SCM_END_FOREIGN_BLOCK): Do
+	not set scm_block_gc.
+
+	* init.c (scm_i_init_guile): Do not set scm_block_gc.
+
+	* deprecation.c (scm_c_issue_deprecation_warning): Use malloc

+
+	* script.c (scm_compile_shell_switches): Added 2005 to Copyright
+	years.

+
+	* gc-card.c (scm_i_sweep_card): Do not increase/decrease
+	scm_gc_running_p.  Sweeping can happen in parallel with
+	allocation.
+
+	* inline.h: Updated comments for current threading implementation.
+
+	* threads.h, threads.c (scm_i_frame_single_threaded): Removed.
+	(scm_i_thread): Removed unused signal_asyncs field.

+	while adding to the global lists.
+
+
+2005-03-08  Marius Vollmer  <mvo@zagadka.de>

+	libltdl is no longer distributed.  We expect it to be installed
+	already.
+
+	* Makefile.am (INCLUDES): Removed @LTDLINCL@.
+	(libguile_la_LIBADD): Removed @LIBLTDL@.
+
+2005-03-07  Marius Vollmer  <mvo@zagadka.de>
+
+	* threads.h, async.h, threads.c (SCM_CRITICAL_SECTION_START,
+	SCM_CRITICAL_SECTION_END): Moved here from threads.h since now
+	they also block/unblock execution of asyncs and call
+	scm_async_click which is declared in async.h but threads.h can not
+	include async.h since async.h already includes threads.h.
+	(scm_i_critical_section_level): New, for checking mistakes in the
+	use of the SCM_CRITICAL_SECTION_* macros.
+	(scm_i_critical_section_mutex): Make it a recursive mutex so that
+	critical sections can be nested.
+

+	(framed_critical_section_mutex): New, used as default for above.
+	(scm_init_threads): Initialize it.
+	(scm_threads_prehistory): Do not initialize thread_admin_mutex and
+	scm_i_critical_section_mutex; both are initialized statically.

+
+	Big merge from the mvo-thread-cleanup branch. The main changes
+	are:

+	  states and continuations barriers.  Fluids have been
+	  reimplemented and can now be garbage collected.
+
+	- Initialization of Guile now works in a multi-thread friendly
+	  manner.  Threads can freely enter and leave guile mode.
+
+	- Blocking on mutexes or condition variables or while selecting
+	  can now be reliably interrupted via system asyncs.
+
+	- The low-level threading interface has been removed.

+	- Signals are delivered via a pipe to a dedicated 'signal delivery
+	  thread'.

+	* eval.c (scm_makprom): Use scm_make_recursive_mutex instead of
+	scm_make_rec_mutex, with all the consequences.
+	(scm_eval_x, scm_eval): Use scm_frame_begin etc instead of

+2004-10-27  Marius Vollmer  <marius.vollmer@uni-dortmund.de>
+
+	First cut at integrating uniform vectors from srfi-4 with the rest
+	of Guile.  This change replaces scm_tc7_byvect with a s8 uniform
+	vector.  The plan is to gradually replace one type after the other

+

+
+	* ramap.c (scm_array_fill_x): For byvect char fill, force signed char

+	info on one filesystem object but open another.  This fstat usage is
+	similar to Emacs copy-file.
+
+	* posix.c (scm_setgroups): Enhance docstring, per doc/ref/posix.texi.
+
+	* simpos.c (scm_system_star): Change scm_from_long to scm_from_int on

+	scm_to_int8, etc.
+
+	* gen-scmconfig.c (SCM_SIZEOF_INTMAX, SCM_SIZEOF_SIZE_T): New.
+

+	conv-integer.i.c and conv-uinteger.i.c, as well.
+
+	* number.h (scm_to_ssize_t, scm_to_size_t): Use the new
+	SCM_I_SSIZE_MIN, SCM_I_SSIZE_MAX, and SCM_I_SIZE_MAX macros for
+	the limits.  Those are always defined.

+	error message.
+
+2004-07-27  Marius Vollmer  <marius.vollmer@uni-dortmund.de>
+
+	* deprecated.h (SCM_FALSEP, SCM_NFALSEP, SCM_BOOLP, SCM_BOOL):
+	Reimplement using scm_is_false, scm_is_true, scm_is_bool, and
+	scm_from_bool, respectively.
+	(SCM_NINUMP): Added.
+
+	* tags.h, deprecated.h (SCM_EQ_P): Deprecated by moving it into

+	SCM_INUM): Deprecated by renaming them to SCM_I_INUMP,
+	SCM_I_NINUMP and SCM_I_INUM, respectively and adding deprecated
+	versions to deprecated.h and deprecated.c.  Changed all uses to
+	either use the SCM_I_ variants or scm_is_*, scm_to_*, or
+	scm_from_*, as appropriate.
+
+	* dynwind.c (scm_i_dowinds): Removed unused code that would call
+	the unexisting scm_cross_dynwind_binding_scope for inums on the
+	windlist.
+
+2004-07-10  Marius Vollmer  <marius.vollmer@uni-dortmund.de>
+
+	* socket.c (ipv6_net_to_num, scm_from_ipv6): Renamed
+	ipv6_net_to_num to scm_from_ipv6, for converting from an IPv6
+	byte-wise address to a SCM integer.  Changed all uses.
+	(ipv6_num_to_net, scm_to_ipv6): Renamed ipv6_num_to_net to
+	scm_to_ipv6 and added type and range checking, for converting from
+	an IPv& byte-wise address to a SCM integer.  Changed all uses.
+	(bignum_in_ipv6_range_p, VALIDATE_INET6): Removed, their function
+	is now done by scm_to_ipv6.
+
+	* numbers.c (scm_to_signed_integer, scm_to_unsigned_integer): dot
+	not accept inexact integers.

+
+2004-07-09  Marius Vollmer  <marius.vollmer@uni-dortmund.de>
+
+	* cpp_cnvt.awk: Use scm_from_int instead of SCM_MAKINUM.
+
+2004-07-10  Kevin Ryde  <user42@zip.com.au>
+
+	* hash.c (scm_hashq, scm_hashv, scm_hash): Restrict to size>=1 rather
+	than size>=0, since 0<=hash<size cannot be satisfied for size==0, and
+	such a size causes divide-by-zeros in scm_hasher.
+
+        * regex-posix.c (scm_make_regexp): Free rx on error, to avoid memory
+	leak.
+
+2004-07-08  Marius Vollmer  <marius.vollmer@uni-dortmund.de>
+
+	* numbers.c (scm_is_signed_integer, scm_is_unsigned_integer):
+	Rewritten using the same logic as scm_to_signed_integer and
+	scm_to_unsigned_integer, respectively, which is better(tm).  Also,
+	use CHAR_BIT instead of hardcoding 8.
+	(LLONG_MIN, LLONG_MAX, ULLONG_MAX): Removed and used
+	SCM_I_LLONG_MIN etc. instead.
+
+	* numbers.h (SCM_MAKINUM, SCM_I_MAKINUM): Renamed SCM_MAKINUM to
+	SCM_I_MAKINUM and changed all uses.
+	* deprecated.h, deprecated.c (SCM_MAKINUM): Newly deprecated.
+
+	* gen-scmconfig.c (SCM_I_LLONG_MIN, SCM_I_LLONG_MAX,

+	them by assuming twos-complement.
+
+2004-07-07  Marius Vollmer  <marius.vollmer@uni-dortmund.de>
+
+	* gen-scmconfig.h.in: Added all the new SCM_I_GSC_*_LIMITS that
+	configure now produces.
+	* gen-scmconfig.c: Use them to output SCM_T_INT8_MIN, etc
+	definitions, giving the limits of the integer types defined by
+	Guile. Also, output a hard coded SCM_I_LLONG_MIN, etc since
+	LLONG_MIN or LONG_LONG_MIN is hard to get at.
+
+	* numbers.h (scm_to_short, scm_to_ushort): It's SHRT_MIN, etc, not
+	SHORT_MIN.
+	(scm_to_size_t): Use SIZE_MAX instead of cooking our own.
+	(scm_to_long_long, scm_to_ulong_long, scm_to_int8, scm_to_uint8,

+	* tags.h (scm_is_eq): New.
+
+	* deprecated.h, boolean.h (SCM_FALSEP, SCM_NFALSEP, SCM_BOOL,
+	SCM_NEGATE_BOOL, SCM_BOOLP): Deprecated by moving into
+	"deprecated.h".  Replaced all uses with scm_is_false, scm_is_true,
+	scm_from_bool, and scm_is_bool, respectively.
+
+	* boolean.h (scm_is_bool): Fix bug in prototype.
+	(scm_from_bool): The argument is "x" not "f", stupid.
+
+	* boolean.c (scm_is_bool): Fix typo.
+
+	* numbers.h, numbers.c (scm_is_integer, scm_is_signed_integer,

+
+2004-07-05  Marius Vollmer  <marius.vollmer@uni-dortmund.de>
+
+	* boolean.h, boolean.c (scm_is_true, scm_is_false, scm_from_bool,
+	scm_to_bool): New.
+
+2004-06-27  Dirk Herrmann  <dirk@dirk-herrmanns-seiten.de>
+
+	* backtrace.c (display_expression, display_frame): Call
+	scm_i_unmemoize_expr for unmemoizing a memoized object holding a
+	single memoized expression.
+
+	* debug.c (memoized_print): Don't try to unmemoize the memoized
+	object, since we can't know whether it holds a single expression
+	or a body.
+
+	(scm_mem_to_proc): Removed check for lambda expression, since it
+	was moot anyway.  Whoever uses these functions for debugging
+	purposes should know what they do: Creating invalid memoized code
+	will cause crashes, independent of whether this check is present
+	or not.
+
+	(scm_proc_to_mem): Take the closure's code as it is and don't
+	append a SCM_IM_LAMBDA isym.  To allow easier debugging, the
+	memoized code should not be modified.
+
+	* debug.[ch] (scm_unmemoize, scm_i_unmemoize_expr): Removed
+	scm_unmemoize from public use, but made scm_i_unmemoize_expr
+	available as a guile internal function instead.  However,
+	scm_i_unmemoize_expr will only work on memoized objects that hold
+	a single memoized expression.  It won't work with bodies.
+
+	* debug.c (scm_procedure_source), macros.c (macro_print), print.c
+	(scm_iprin1): Call scm_i_unmemocopy_body for unmemoizing a body,
+	i. e. a list of expressions.
+
+	* eval.c (unmemoize_exprs): Drop internal body markers from the
+	output during unmemoization.
+
+	* eval.[ch] (scm_unmemocopy, scm_i_unmemocopy_expr,
+	scm_i_unmemocopy_body): Removed scm_unmemocopy from public use,
+	but made scm_i_unmemocopy_expr and scm_i_unmemocopy_body available
+	as guile internal functions instead.  scm_i_unmemoize_expr will
+	only work on a single memoized expression, while
+	scm_i_unmemocopy_body will only work on bodies.
+
+2004-06-21  Dirk Herrmann  <dirk@dirk-herrmanns-seiten.de>
+
+	* eval.c (unmemoize_exprs): Handle semi-memoized code.
+
+	(scm_cons_source, scm_primitive_eval): Prefer higher level
+	predicate SCM_FALSEP over SCM_IMP.
+
+2004-06-15  Rob Browning  <rlb@defaultvalue.org>
+
+	* script.c (scm_shell_usage): minor phrasing change.
+
+	* gc_os_dep.c: update ifdefery for macosx.
+	(scm_get_stack_base): separate result initialization from
+	declaration to slience warnings with macosx and hp-ux using gcc
+	3.3.  Thanks to Andreas Vögele.
+
+2004-06-13  Han-Wen Nienhuys   <hanwen@xs4all.nl>
+
+	* eval.c (unmemoize_exprs): use SCM_CONSP for the loop condition.
+
+2004-06-06  Dirk Herrmann  <dirk@dirk-herrmanns-seiten.de>
+
+	* list.[ch] (scm_i_finite_list_copy): New internal function to
+	copy lists that are known to be finite (though not necessarily
+	proper).
+
+	* debug.c (scm_procedure_source): Don't have scm_unmemocopy treat
+	a closure's argument list like an expression of a body.
+
+	* eval.c (unmemoize_expression, unmemoize_exprs, unmemoize_and,
+	unmemoize_begin, unmemoize_case, unmemoize_cond, unmemoize_delay,
+	unmemoize_do, unmemoize_if, unmemoize_lambda, unmemoize_let,
+	unmemoize_letrec, unmemoize_letstar, unmemoize_or,
+	unmemoize_set_x, unmemoize_apply, unmemoize_atcall_cc,
+	unmemoize_at_call_with_values, unmemoize_future, sym_atslot_ref,
+	unmemoize_atslot_ref, sym_atslot_set_x, unmemoize_atslot_set_x,
+	unmemoize_builtin_macro): New static functions and symbols.
+
+	(scm_unmemocopy): Rewritten in terms of the above.  scm_unmemocopy
+	now has a slightly different meaning: The memoized form that is
+	receives as its argument is now interpreted as a sequence of
+	expressions from a body.
+
+	(unmemocar, scm_unmemocar): Since the whole functionality of
+	unmemocar and scm_unmemocar is not needed any more, scm_unmemocar
+	has its old content back and is deprecated, while unmemocar has
+	been removed.
+
+	(SCM_BIT7): Removed.
+
+	(CEVAL): For unmemoizing a single expression, call
+	unmemoize_expression instead of scm_unmemocopy, which now expects
+	a sequence of body expressions.  Eliminated unnecessary empty
+	environment frame when executing let* forms.  Eliminated
+	unmemoization step from evaluator.
+
+2004-06-02  Marius Vollmer  <marius.vollmer@uni-dortmund.de>
+
+	* eval.c (scm_macroexp, macroexp): Renamed scm_macroexp to
+	macroexp and made static.  Added new version of scm_macroexp that
+	emits a deprecation warning and then calls macroexp.
+	(scm_m_undefine): Issue deprecation warning.
+
+2004-05-30  Dirk Herrmann  <dirk@dirk-herrmanns-seiten.de>
+
+	* eval.c (lookup_global_symbol, literal_p, try_macro_lookup):
+	Modified to make set! work on symbols that represent syntactic
+	keywords.
+
+2004-05-26  Han-Wen Nienhuys   <hanwen@xs4all.nl>
+
+	* gc.h (SCM_CELL_OBJECT_LOC): use SCM_GC_CELL_OBJECT to prevent
+	compound expression as lvalue errors.
+
+2004-05-24  Marius Vollmer  <mvo@zagadka.de>
+
+	* dynwind.c (winder_mark): Use SCM_PACK to correctly convert the
+	WINDER_DATA to a SCM.
+
+2004-05-24  Dirk Herrmann  <dirk@dirk-herrmanns-seiten.de>
+
+	* goops.c (compute_getters_n_setters, create_standard_classes,
+	scm_add_slot): Compute closures by calling scm_i_eval_x on a
+	lambda expression rather than creating them with scm_closure.
+
+2004-05-22  Dirk Herrmann  <dirk@dirk-herrmanns-seiten.de>
+
+	* eval.c (s_macro_keyword, scm_m_set_x): Remove checking for
+	misplaced syntactic keywords.  This will not work unless guile's
+	defmacro feature is deprecated.
+
+	(scm_m_case): Fixed a bug that caused the list of labels to grow
+	with every case form.
+
+2004-05-19  Kevin Ryde  <user42@zip.com.au>
+
+	* numbers.c (scm_round_number): For inum and big, just return x.  For
+	real, use scm_round for 2^54-1 etc problems covered there.
+
+	* numbers.c (trunc): Remove #define to scm_truncate when the C library
+	doesn't provide trunc.  This was for when `truncate' was done as a
+	scm_tc7_dsubr, no longer required.
+
+	* threads.c (scm_threads_mark_stacks) [SCM_STACK_GROWS_UP]: Correction
+	to stack marking call, two parameters and no cast on t->base.
+
+2004-05-18  Marius Vollmer  <mvo@zagadka.de>
+
+	* hashtab.c (rehash_after_gc): Bug fix: properly link the
+	processed hashtables back into the weak_hashtables list.  Thanks
+	to Bill Schottstaedt!
+
+2004-05-16  Dirk Herrmann  <dirk@dirk-herrmanns-seiten.de>
+
+	* eval.c (unmemoize_quote): New static function.
+
+	(scm_m_quote, scm_m_atslot_ref, SCM_CEVAL): Changed the byte code
+	representation of 'quote' and '@slot-ref' to an improper list.
+	This reduces execution time, the number of cells used to hold the
+	memoized code, and thus also reduces garbage collection time.
+
+	(scm_unmemocopy): Use unmemoize_quote for quote expressions.
+
+	(SCM_CEVAL): Changed macro handling to also work with macros that
+	return improper lists.  Added an assertion, that the code returned
+	by a macro transformer will not lead to cycles in the memoized
+	code.
+
+2004-05-15  Dirk Herrmann  <dirk@dirk-herrmanns-seiten.de>
+
+	No functional change, just rearrangements of functions within the
+	file.
+
+	* eval.c (scm_ilookup, scm_unbound_variable_key,
+	error_unbound_variable, scm_lookupcar1, scm_lookupcar): Moved to
+	the definitions used for execution, since that's where they will
+	belong to later.
+
+2004-05-15  Dirk Herrmann  <dirk@dirk-herrmanns-seiten.de>
+
+	* numbers.h (SCM_SLOPPY_FRACTIONP): Removed.  It was not used
+	throughout guile, has not been part of an official release yet,
+	and the concept of sloppy predicates has never been a good idea.
+
+	(SCM_FRACTION_NUMERATOR, SCM_FRACTION_DENOMINATOR,
+	SCM_FRACTION_SET_NUMERATOR, SCM_FRACTION_SET_DENOMINATOR):
+	Simplified.
+
+2004-05-15  Dirk Herrmann  <dirk@dirk-herrmanns-seiten.de>
+
+	* throw.c (SETJBJMPBUF, SCM_SETJBDFRAME): Add cast to scm_t_bits
+	to make explicit what happens.
+
+2004-05-15  Dirk Herrmann  <dirk@dirk-herrmanns-seiten.de>
+
+	* dynl.c (SET_DYNL_HANDLE): Add cast to scm_t_bits to make
+	explicit what happens.
+
+	* guardians.c (TCONC_IN): Use SCM_SET_CELL_OBJECT_x rather than
+	SCM_SET_CELL_WORD_x when writing scheme objets to cell elements.
+
+2004-05-11  Marius Vollmer  <mvo@zagadka.de>
+
+	* scmsigs.c (scm_sigaction_for_thread): Validate that the handler
+	is indeed a procedure when it isn't a number.
+
+2004-05-10  Marius Vollmer  <mvo@zagadka.de>
+
+	Convert floating point numbers into strings with an arbitrary
+	radix.  Thanks to Richard Todd!
+
+	* numbers.c (FLOBUFLEN): Increase so that radix 2 strings will
+	fit.
+	(fx): Removed.
+	(scm_dblprec, fx_per_radix, init_dblprec, init_fx_radix,
+	number_chars): New, to support variable radices.
+	(idbl2str): Use above instead of the old base-10 only tables.
+	(iflo2str): Pass on new RADIX argument to idbl2str.
+	(scm_number_to_string): Pass radix to iflo2str.
+	(scm_print_real, scm_print_complex): Explicitly pass radix 10 to
+	iflo2str.
+	(scm_init_numbers): Call init_dblprec and init_fx_radix for all
+	possible radices.
+
+2004-05-10  Kevin Ryde  <user42@zip.com.au>
+
+	* numbers.c (scm_logbit_p): Correction to test above the end of an
+	inum.  Reported by Jan Konecny.
+
+2004-05-06  Marius Vollmer  <marius.vollmer@uni-dortmund.de>
+
+	* gc.h (scm_t_cell): Fields are now of type SCM instead of
+	scm_t_bits.  Updated all users.
+	(SCM_GC_CARD_SIZE_MASK): Use SCM_GC_SIZEOF_CARD instead of
+	duplicating the code.
+	(SCM_CELL_OBJECT_LOC): New.
+	(SCM_CARLOC, SCM_CDRLOC): Use it instead of SCM_CELL_WORD_LOC.
+	(SCM_CELL_WORD_LOC): Moved to "deprecated.h".
+
+	* smob.h (SCM_SMOB_DATA_2, SCM_SMOB_DATA_3, SCM_SMOB_FLAGS,
+	SCM_SET_SMOB_DATA_2, SCM_SET_SMOB_DATA_3, SCM_SET_SMOB_FLAGS,

+	SCM_SET_SMOB_OBJECT, SCM_SET_SMOB_OBJECT_2, SCM_SET_SMOB_OBJECT_3,
+	SCM_SMOB_OBJECT_LOC, SCM_SMOB_OBJECT_2_LOC,
+	SCM_SMOB_OBJECT_3_LOC): New.
+	* smob.c (scm_i_set_smob_flags): New function.
+
+	* dynl.c, dynwind.c, eval.h, fluids.h, futures.h, hashtab.h,
+	hooks.h, keywords.h, macros.h, macros.c, mallocs.c, mallocs.h,
+	random.h, regex-posix.h, root.h, srcprop.h, srcprop.c, threads.h:
+	Use SCM_SMOB_* instead of SCM_CELL_* as appropriate.  Use
+	SCM_SMOB_FLAGS and SCM_SET_SMOB_FLAGS instead of accessing the
+	zeroth word directly.  Use SCM_SMOB_PREDICATE as appropriate.
+
+	* numbers.h (SCM_I_BIG_MPZ): Use SCM_CELL_OBJECT_LOC instead of
+	taking the address of SCM_CELL_WORD_1, the latter being no longer
+	an lvalue.
+
+	* variable.h (SCM_VARIABLE_LOC): Use SCM_CELL_OBJECT_LOC instead
+	of casting SCM_CELL_WORD_LOC.
+
+2004-05-02  Kevin Ryde  <user42@zip.com.au>
+
+	* eval.c (scm_macroexp): Add prototype, since it's not in eval.h under
+	--disable-deprecated.  Reported by Andreas Vögele.
+
+	* filesys.c (_POSIX_C_SOURCE): Define to 199506L to get readdir_r (in
+	particular on HP-UX).  Reported by Andreas Vögele.
+
+	* list.c (varargs.h): Remove, leave just stdarg.h which is all the
+	code has support for.  Fixes building with AIX cc, which is ansi but
+	doesn't define __STDC__.  Reported by Keith Crane.
+	(var_start): Remove macro, this variation no longer required.
+	(scm_list_n): Use va_start directly.
+
+2004-05-01  Kevin Ryde  <user42@zip.com.au>
+
+	* continuations.c (scm_dynthrow): Use >= instead of SCM_PTR_GE which
+	is now gone.  Reported by Andreas Vögele.
+
+2004-04-28  Kevin Ryde  <user42@zip.com.au>
+
+	* backtrace.c (display_frame_expr), numbers.c (XDIGIT2UINT,
+	mem2uinteger, mem2decimal_from_point, mem2ureal): Cast char to int for
+	ctype.h tests, to avoid warnings from gcc on HP-UX about char as array
+	subscript.  Reported by Andreas Vögele.
+	Also cast through unsigned char to avoid passing negatives to those
+	macros if input contains 8-bit values.
+
+	* num2integral.i.c (NUM2INTEGRAL): Under non-BIGMPZ_FITSP case,
+	corrections to range check for signed numbers.  Remove
+	scm_remember_upto_here_1(num) from these checks, since num is used
+	subsequently anyway.
+
+	* num2integral.i.c (NUM2INTEGRAL): Test BIGMPZ_FITSP with "!= 0" to
+	avoid warning from gcc 3.4.  Reported by Hyperdivision.
+
+	* numbers.c (scm_bit_extract): Use min instead of MIN.
+	(MIN): Remove, this conflicts with similar macro defined by limits.h
+	on HP-UX.  Reported by Andreas Vögele.
+
+	* stime.c (_POSIX_C_SOURCE): Define to 199506L to get gmtime_r (in
+	particular on HP-UX).  Reported by Andreas Vögele.
+
+	* threads.c (scm_threads_mark_stacks): Correction sizet -> size_t.
+	Reported by Andreas Vögele.
+
+	* threads-plugin.h (SCM_MUTEX_MAXSIZE): Increase to 25*sizeof(long),
+	for the benefit of hpux11 where pthread_mutex_t is 88 bytes.  Reported
+	by Andreas Vögele.
+
+2004-04-22  Dirk Herrmann  <dirk@dirk-herrmanns-seiten.de>
+
+	* eval.c (s_macro_keyword): New static identifier.
+
+	(scm_m_define): Change order to first create binding and
+	evaluating the expression afterwards.
+
+	(scm_m_set_x): Memoize complete set! expression.  Only leave
+	symbols if no binding exists at memoization time.  Throw error if
+	assigning to a syntactic keyword.
+
+	(lazy_memoize_variable): New function.
+
+	(CEVAL): When execution set!, perform lazy memoization if
+	unmemoized symbol is detected.
+
+	* modules.c (module_variable): Return variables with unbound
+	value.
+
+	* tags.h: Fix comment.
+
+2004-04-25  Kevin Ryde  <user42@zip.com.au>
+
+	* chars.c (scm_char_upcase, scm_char_downcase, scm_c_upcase,
+	scm_c_downcase): Use ctype.h toupper and tolower.  This will be useful
+	in 8-bit locales, and ensures consistency with char-upper-case? and
+	char-lower-case? which already use ctype.h.
+	(scm_c_upcase_table, scm_c_downcase_table, scm_lowers, scm_uppers):
+	Remove.
+	* chars.c, chars.h, init.c (scm_tables_prehistory): Remove.
+
+	* socket.c (VALIDATE_INET6): Correction to bignum_in_ipv6_range_p
+	call.  Reported by Hyperdivision.
+
+	* threads.c (scm_yield): Correction, actually call scm_thread_yield.
+	Reported by Hyperdivision.
+
+	* unif.c (s_scm_make_uve): Remove unused local variable.  Reported by
+	Hyperdivision.
+
+2004-04-22  Dirk Herrmann  <dirk@dirk-herrmanns-seiten.de>
+
+	Hide the implementation of ilocs and isyms in eval.c.
+
+	* deprecated.h (SCM_IFRINC, SCM_ICDR, SCM_IFRAME, SCM_IDIST,
+	SCM_ICDRP), eval.c (SCM_IFRINC, SCM_ICDR, SCM_IFRAME, SCM_IDIST,
+	SCM_ICDRP), eval.h (SCM_ICDR, SCM_IFRINC, SCM_IFRAME, SCM_IDIST,
+	SCM_ICDRP): Deprecated and added to deprecated.h.  Moved from
+	eval.h to eval.c.
+
+	* deprecated.c (scm_isymnames), deprecated.h (scm_isymnames,
+	SCM_ISYMNUM, SCM_ISYMCHARS), eval.c (SCM_ISYMNUM, isymnames,
+	scm_unmemocopy, CEVAL), print.c (scm_isymnames), tags.h
+	(SCM_ISYMNUM, scm_isymnames, SCM_ISYMCHARS): Deprecated
+	scm_isymnames, SCM_ISYMNUM and SCM_ISYMCHARS and added to
+	deprecated.[hc].  Moved scm_isymnames from print.c to eval.c and
+	renamed to isymnames.  Moved SCM_ISYMNUM from tags.h to eval.c and
+	renamed to ISYMNUM.
+
+	* eval.c (scm_i_print_iloc, scm_i_print_isym), eval.h
+	(scm_i_print_iloc, scm_i_print_isym), print.c (scm_iprin1):
+	Extracted printing of ilocs and isyms to guile internal functions
+	scm_i_print_iloc, scm_i_print_isym of eval.c.
+
+2004-04-22  Kevin Ryde  <user42@zip.com.au>
+
+	* numbers.c (scm_bit_extract): Use SCM_SRS for signed right shift.
+
+	* numbers.c (scm_round): Test for x already an integer, to avoid bad
+	rounding in x+0.5 when x is a big value already an integer.  In
+	certain hardware rounding cases x+0.5 can give an adjacent integer,
+	leading to that as the result, when we really just wanted x itself.
+
+2004-04-19  Dirk Herrmann  <dirk@dirk-herrmanns-seiten.de>
+
+	* eval.c (scm_unmemocopy): Fixed unmemoization of let*.
+
+	(deval_args, CEVAL): Minor improvements: Reduced variable scopes,
+	added const qualifiers, cast intentionally unused expressions to
+	void for emphasis, improved comment.
+
+2004-04-18  Dirk Herrmann  <dirk@dirk-herrmanns-seiten.de>
+
+	* tags.h (scm_tags, scm_tc8_tags, scm_tc9_flag, scm_tc8_flag,
+	scm_tc8_isym): Renamed scm_tags to scm_tc8_tags.  Renamed
+	scm_tc9_flag to scm_tc8_flag.  Introduced new identifier
+	scm_tc8_isym.  Defined tc8-tags relative to scm_tc3_imm24.
+	Defined the tc8-tag for flags to be 0x04, which will mean that
+	SCM_BOOL_F will also have the value 0x04 instead of 0x013c.  Due
+	to the reduced number of bits and the simpler bit pattern for
+	SCM_BOOL_F, certain machines may be able to use more efficient
+	processor instructions to deal with SCM_BOOL_F.
+
+	(SCM_ITAG9, SCM_MAKE_ITAG9, SCM_ITAG9_DATA): Removed.  These have
+	never been defined in a released version, thus no need to
+	deprecate them.
+
+	(SCM_IFLAGP, SCM_MAKIFLAG, SCM_IFLAGNUM): Flags now use tc8
+	instead of tc9 tags.
+
+	(SCM_ISYMP, SCM_MAKISYM, SCM_ISYMNUM): Isyms now use tc8 instead
+	of tc9 tags.
+
+	(SCM_MAKSPCSYM): Removed.  It is almost impossible that user code
+	could have used this definition.
+
+	(SCM_IM_AND, SCM_IM_BEGIN, SCM_IM_CASE, SCM_IM_COND, SCM_IM_DO,
+	SCM_IM_IF, SCM_IM_LAMBDA, SCM_IM_LET, SCM_IM_LETSTAR,
+	SCM_IM_LETREC, SCM_IM_OR, SCM_IM_QUOTE, SCM_IM_SET_X): Now encoded
+	as isyms, as special isyms don't exist any more.
+
+2004-04-18  Kevin Ryde  <user42@zip.com.au>
+
+	* filesys.c (scm_readdir): Use readdir_r when available, for thread
+	safety.
+
+	* numbers.c (scm_max, scm_min): For big/real, use SCM_SWAP rather than
+	explicit swapping code.
+
+2004-04-15  Kevin Ryde  <user42@zip.com.au>
+
+	* cpp_sig_symbols.in: Add SIGSYS.
+
+	* list.c (scm_append_x): Use iterative style, to avoid non-tail
+	recursion.
+
+	* numbers.c (scm_max, scm_min): For inum/frac, frac/inum, big/frac,
+	frac/big and frac/frac, use scm_less_p for exact comparison.
+
+	* numbers.c (scm_gcd): For inum/big, use mpz_gcd_ui by sharing code
+	with big/inum.
+
+	* numbers.c (xisinf): Add a comment about solaris 7 lacking isinf.
+
+2004-04-06  Han-Wen Nienhuys   <hanwen@xs4all.nl>
+
+	* inline.h (scm_cell): use SCM_GC_CELL_WORD for checking tag.
+
+	* chars.h (scm_init_chars): change scm_{upcase,downcase} to
+	scm_c_{up,down}case.
+	(SCM_MAKE_CHAR): add (unsigned char) cast. This prevents havoc
+	when hi-bit ASCII is subjected to SCM_MAKE_CHAR().
+
+2004-04-06  Kevin Ryde  <user42@zip.com.au>
+
+	* numbers.c (scm_ash): Remove stray "}" in docstring.
+
+	* numbers.c (scm_make_ratio): For inum/bignum integer detection, use
+	x==SCM_MOST_NEGATIVE_FIXNUM explicitly, for clarity and to avoid
+	calling mpz_cmp_ui in most cases.
+
+	* numbers.c (scm_quotient, scm_remainder): In inum/big, use mpz_cmp_ui
+	for big == abs(most-negative-fixnum) special case.
+	(abs_most_negative_fixnum): Remove, no longer used.
+
+	* scmsigs.c (scm_sigaction_for_thread): Correction to signum range
+	test, avoids SCM_VECTOR_REF outside bounds of signal_handlers on
+	calling (sigaction NSIG).
+
+	* simpos.c (scm_system_star): Fix execargv memory leak, merge parent
+	and fork error cases to do this.
+
+2004-04-03  Dirk Herrmann  <dirk@dirk-herrmanns-seiten.de>
+
+	* eval.c (CEVAL): Don't distinguish between short and long
+	instructions when dispatching - just always dispatch on the
+	instruction code, which is common for short and long instructions.
+	Further, removed unnecessary goto statements and added comment.
+
+2004-04-03  Dirk Herrmann  <dirk@dirk-herrmanns-seiten.de>
+
+	* eval.c (scm_unmemocopy): Don't distinguish between short and
+	long instructions when dispatching - just always dispatch on the
+	instruction code, which is common for short and long instructions.
+	Further, removed unnecessary goto statements, fixed indentation
+	and replaced SCM_IMP predicates by SCM_NULLP.
+
+2004-04-03  Dirk Herrmann  <dirk@dirk-herrmanns-seiten.de>
+
+	* eval.c (scm_lookupcar1, CEVAL): Use SCM_ILOCP instead of
+	comparison with SCM_ILOC00.  In CEVAL, eliminate goto-label
+	'checkmacro'.
+
+2004-03-31  Kevin Ryde  <user42@zip.com.au>
+
+	* simpos.c: Include <signal.h> for SIG_IGN and friends.
+
+2004-03-29  Dirk Herrmann  <dirk@dirk-herrmanns-seiten.de>
+
+	Introduce scm_debug_mode_p as a replacement for scm_debug_mode and
+	SCM_DEBUGGINGP:
+
+	* debug.h (scm_debug_mode_p, scm_debug_mode, SCM_DEBUGGINGP),
+	eval.c (scm_debug_mode_p): Deprecated scm_debug_mode and
+	SCM_DEBUGGINGP.  Provided scm_debug_mode_p instead, to have one
+	single interface that also matches the naming conventions.
+	Probably scm_debug_mode_p should be part of the private interface
+	anyway.
+
+	* debug.h (scm_debug_mode_p), backtrace.c (display_error_body),
+	eval.c (SCM_APPLY, scm_trampoline_0, scm_trampoline_1,
+	scm_trampoline_2): Change uses of scm_debug_mode or SCM_DEBUGGINGP
+	to scm_debug_mode_p.
+
+
+	Deprecate direct access to scm_ceval, scm_deval and scm_ceval_ptr:
+
+	* eval.h (scm_ceval, scm_deval, scm_ceval_ptr), debug.h
+	(scm_ceval_ptr): Deprecated.  Moved declaration of scm_ceval_ptr
+	from debug.h to eval.h.
+
+	* debug.h (SCM_RESET_DEBUG_MODE): Don't access scm_ceval_ptr any
+	more, just leave it with setting scm_debug_mode_p, which is
+	equivalent for practical purposes.
+
+	* deprecated.h (SCM_XEVAL, SCM_XEVALCAR): Call scm_i_eval_x
+	instead of *scm_ceval_ptr.  Leave all evaluating to scm_i_eval_x.
+
+	* gdbint.c (gdb_eval): Call scm_i_eval_x instead of scm_ceval.
+
+	* eval.c (ceval, deval, scm_ceval, scm_deval): Made scm_ceval
+	static and renamed it to ceval throughout.  Provide a new exported
+	but deprecated function scm_ceval as a wrapper for backwards
+	compatibility.  The same is done for the deval/scm_deval pair of
+	functions.
+
+	* eval.c (CEVAL, SCM_CEVAL): Renamed SCM_CEVAL to CEVAL
+	throughout.  Defined CEVAL to ceval or deval, based on compilation
+	phase.
+
+	* eval.c (SCM_XEVAL, SCM_XEVALCAR): Dispatch on scm_debug_mode_p
+	to ceval and deval instead of calling *scm_ceval_ptr.
+
+	* eval.c (dispatching_eval): New deprecated static function.
+
+	* eval.c (scm_ceval_ptr): Initialized to dispatching_eval in order
+	to emulate its old behaviour as closely as possible.
+
+
+	Change the evaluator such that only expressions for which pair? is
+	true are passed to CEVAL, and such that all other expressions are
+	evaluated outside of CEVAL:
+
+	* eval.c (EVAL): New, provided in analogy to EVALCAR.  Evaluate an
+	expression that is assumed to be memoized already.  All but
+	expressions of the form '(<form> <form> ...)' are evaluated inline
+	without calling an evaluator.
+
+	* eval.c (SCM_XEVAL, SCM_XEVALCAR, EVALCAR): Evaluate all but
+	expressions of the form '(<form> <form> ...)' inline without
+	calling an evaluator.
+
+	* eval.c (scm_i_eval_x, scm_i_eval, scm_ceval, scm_deval): Handle
+	the special case of unmemoized symbols passed on the top level.
+
+	* eval.c (CEVAL): Change calls to CEVAL to EVAL, except where it
+	is known that the expression passed to CEVAL is of the form
+	'(<form> <form> ...)'.  Remove handling of the tc7-objects, since
+	now it is known that the input expression of CEVAL is a pair.
+
+2004-03-29  Dirk Herrmann  <dirk@dirk-herrmanns-seiten.de>
+
+	* eval.c (is_self_quoting_p): New static function.
+
+	(scm_m_quote): Use is_self_quoting_p.
+
+	(copy_tree): Corrected typo in comment.
+
+2004-03-28  Han-Wen Nienhuys   <hanwen@xs4all.nl>
+
+	* eval.c (s_scm_copy_tree): idem.
+
+	* list.c (s_scm_filter): remove "pointer" from doc string.
+
+	* gc.h (SCM_GC_CELL_TYPE): SCM_GC_CELL_TYPE uses SCM_GC_CELL_OBJECT.
+
+	* goops.h (SCM_NUMBER_OF_SLOTS): don't SCM_UNPACK the result.
+
+	* backtrace.c ("display_backtrace_body"): SCM_PACK before SCM_EQ_P
+	(display_frame): idem.
+	(display_backtrace_file_and_line): idem.
+
+	* tags.h (SCM_UNPACK): stricter typechecking on SCM_UNPACK
+	arguments.
+
+2004-03-26  Kevin Ryde  <user42@zip.com.au>
+
+	* filesys.c (scm_getcwd, scm_readlink): Avoid memory leak on errors.
+
+	* numbers.c (scm_modulo): For inum/big and big/big, remove test of
+	big==0 since that never occurs.
+
+	* numbers.c, numbers.h (scm_modulo_expt): Renamed from
+	scm_modular_expt, matching scheme level name `modulo-expt'.
+
+	* numbers.c (scm_modular_expt): Return a negative remainder for a
+	negative divisor, the same as `modulo' does.
+
+2004-03-26  Eric Hanchrow <offby1@blarg.net>
+
+	* numbers.c, numbers.h (scm_modular_expt): New function.
+
+2004-03-25  Kevin Ryde  <user42@zip.com.au>
+
+	* numbers.c (scm_min, scm_max): Correction to big/real and real/big,
+	return inexact as required by r5rs.
+
+2004-03-24  Dirk Herrmann  <dirk@dirk-herrmanns-seiten.de>
+
+	* eval.c: Separated some definitions relevant for execution from
+	the memoization part of the file.
+
+	(copy_tree): New static function
+
+	(scm_copy_tree): Rewritten to fix two kinds or bugs: First, cyclic
+	structures are detected now and will lead to an exception instead
+	of forcing guile to run in an endless loop, using up all the
+	system's memory.  Second, arrays in the cdr of an improper list
+	are now copied.  See the new test cases in eval.test.
+
+2004-03-24  Dirk Herrmann  <dirk@dirk-herrmanns-seiten.de>
+
+	* posix.c (scm_gethostname): Make sure len is initialised before
+	it is used.  Restructured to (hopefully) represent possible
+	configurations more clearly in the code.  Added unwind handler.
+
+2004-03-23  Kevin Ryde  <user42@zip.com.au>
+
+	* posix.c (scm_gethostname): Use sysconf(_SC_HOST_NAME_MAX) and/or
+	MAXHOSTNAMELEN when available.
+
+2004-03-21  Marius Vollmer  <mvo@zagadka.de>
+
+	* read.c (skip_scsh_block_comment): Also recognize '\r' as a line
+	terminator.  Rewritten the logic as a state machine, I must have
+	been doing too much VHDL lately...
+
+	* eval.c (scm_ceval, scm_deval): Explicitely evaluate ports to
+	themselves.  Thanks to Han-Wen Nienhuys!
+
+	* list.c: Changed docstrings so that they no longer talk about
+	returning 'pointers' to something.
+
+2004-03-20  Han-Wen Nienhuys   <hanwen@xs4all.nl>
+
+	* gc.c: remove set_debug_cell_accesses! when
+	SCM_DEBUG_CELL_ACCESSES is not defined. Scheme source code should
+	use (if (defined? 'set-debug-cell-accesses!) .. ) to switch on
+	debugging conditionally.
+
+2004-03-21  Kevin Ryde  <user42@zip.com.au>
+
+	* stime.c (scm_gmtime): Use gmtime_r when available, for thread safety.
+
+2004-03-20  Kevin Ryde  <user42@zip.com.au>
+
+	* posix.c (scm_gethostname): Preserve errno across free() call.
+
+2004-03-18  Han-Wen Nienhuys   <hanwen@xs4all.nl>
+
+	* gc-card.c (sweep_card): use SCM_GC_SET_CELL_WORD for setting
+	free cells.
+
+2004-03-14  Kevin Ryde  <user42@zip.com.au>
+
+	* stime.c: Define _GNU_SOURCE for strptime prototype from glibc.
+	(strptime): Use	HAVE_DECL_STRPTIME for when to give own prototype.

+2004-03-07  Kevin Ryde  <user42@zip.com.au>
+
+	* stime.c (scm_gmtime): Return bd_time->tm_zone when available, rather
+	than "GMT" always.
+	(filltime): Make zname parameter "const".
+
+2004-03-03  Mikael Djurfeldt  <mdj@chunk.mit.edu>
+
+	* threads.c, threads.h (scm_c_scm2thread): New function.
+
+2004-02-29  Kevin Ryde  <user42@zip.com.au>
+
+	* numbers.c (guile_ieee_init): Use C99 INFINITY and NAN when
+	available.  Test HAVE_DINFINITY and HAVE_DQNAN for those globals, in
+	particular don't assume "defined (__alpha__) && ! defined (linux)"
+	means OSF.  Remove "SCO" code, which was not really SCO specific and
+	which John W. Eaton advises should be long past being needed.
+
+	* posix.c (scm_execl, scm_execlp, scm_execle): Avoid memory leak under
+	error throw.
+
+2004-02-24  Kevin Ryde  <user42@zip.com.au>
+
+	* posix.c (scm_cuserid): Use a private result buffer, for thread safe.
+
+2004-02-22  Kevin Ryde  <user42@zip.com.au>
+
+	* numbers.c (scm_max, scm_min): For one arg, dispatch to generic for
+	complex, same as for two args.  (Handle only inum, big, real, frac).
+
+2004-02-21  Kevin Ryde  <user42@zip.com.au>
+
+	* posix.c (scm_crypt): Use new HAVE_CRYPT.
+	(<crypt.h>): Remove HAVE_LIBCRYPT condition.
+	Reported by Andreas Voegele.
+
+2004-02-20  Neil Jerram  <neil@ossau.uklinux.net>
+
+	* list.c (scm_list_n): Add #if SCM_DEBUG_CELL_ACCESSES_P around
+	validation.
+
+	* read.c (scm_lreadparen): Removed.
+	(scm_lreadparen1): Renamed scm_i_lreadparen.
+
+2004-02-20  Han-Wen Nienhuys   <hanwen@xs4all.nl>
+
+	* list.c (scm_list_n): validate non-immediate arguments;
+	this will catch forgotten a SCM_UNDEFINED.
+
+2004-02-18  Marius Vollmer  <mvo@zagadka.de>
+
+	* gc.h (scm_gc_cells_collected): Removed duplicated declaration.
+	Thanks to Bill Schottstaedt!
+
+	* socket.h (scm_gethost): Removed prototype it is already in
+	"net_db.h".  Thanks to Bill Schottstaedt!
+
+2004-02-18  Kevin Ryde  <user42@zip.com.au>
+
+	* num2integral.i.c (INTEGRAL2BIG): WORDS_BIGENDIAN not right for word
+	order parameter to mpz_import, in fact with just one word there's no
+	order to worry about at all.
+
+	* numbers.c (scm_num_eq_p): For real==frac, complex==frac, frac==real
+	and frac==complex, make an exact comparison rather than converting
+	with fraction2double.
+
+	* posix.c, putenv.c, stime.c (environ): Use _NSGetEnviron in Darwin
+	shared library, since environ is not directly available there.
+
+	* script.c (scm_shell_usage): Print to stdout for --help, per GNU
+	standard.
+
+	* stime.c (scm_localtime, scm_gmtime, scm_mktime): Provide a default
+	errno EINVAL in case localtime and gmtime don't set it.
+	(scm_mktime, scm_strptime): Forcibly use errno EINVAL for our
+	SCM_SYSERROR, since mktime and strptime generally don't set errno.
+
+2004-02-16  Kevin Ryde  <kevin@swox.se>
+
+	* gc-malloc.c (scm_done_malloc, scm_done_free): Allow negative sizes,
+	which were permitted in the past for these.
+
+	* num2float.i.c (NUM2FLOAT): Expand isfinite to !xisinf, as per
+	previous change to numbers.c.
+
+	* script.c (scm_shell_usage): Print bug-guile email address, as per

+
+	* hashtab.c, hashtab.h (scm_hash_map_to_list): Renamed from
+	scm_hash_map.
+	(scm_hash_fold): Use scm_call_3 directly in the call to
+	scm_internal_hash_fold instead of going via fold_proc (which is
+	now removed).
+	(scm_hash_for_each): Use a trampoline +
+	scm_internal_hash_for_each_handle.
+	(scm_internal_hash_for_each_handle, scm_hash_for_each_handle): New
+	functions.
+
+2004-02-12  Kevin Ryde  <user42@zip.com.au>
+
+	* ports.c (scm_port_line): In docstring, note first line is 0.
+	(scm_set_port_line_x): In docstring, note first line is 0.
+	(scm_port_column): In docstring, there's no default to current input
+	port, and remove shared port-line @defun.
+	(scm_set_port_column_x): In docstring, there's no default to current
+	input port, note first column is 0, remove shared set-port-line!
+	@defun.
+
+	* ramap.c (scm_array_fill_x): For fvect and dvect, use scm_num2dbl to
+	convert args the same way that array-set! does.
+
+	* unif.c (scm_make_uve, scm_array_p): Allow fraction 1/3 as prototype
+	for dvect.
+	(scm_array_p): Add missing "break"s in switch, fix llvect test look
+	for "l" not "s", fix dvect to be false for singp(prot) since such a
+	value is for fvect.
+	(scm_array_prototype): Return 1/3 for dvect, rather than 0.33..33.
+	(exactly_one_third): New variable.

+	* dynwind.h, dynwind.c: Did the following renamings:
+	scm_begin_frame -> scm_frame_begin,
+	scm_end_frame -> scm_frame_end,
+	scm_on_unwind -> scm_frame_unwind,
+	scm_on_rewind -> scm_frame_rewind,

+
+2004-01-06  Marius Vollmer  <marius.vollmer@uni-dortmund.de>
+
+	* ports.c (swap_ports, scm_with_current_foo_port): Do not allocate

+
+	* fluids.h, fluids.c (scm_make_initial_fluids, scm_copy_fluids,
+	scm_swap_fluids, scm_swap_fluids_reverse): Renamed to

+	scm_begin_frame, scm_end_frame, scm_on_unwind, scm_on_rewind):
+	New.
+	(scm_dowinds, scm_i_dowinds): scm_dowinds has been renamed to
+	scm_i_dowinds and extended to handle frames and to invoke a 'turn'
+	function when the outermost wind point has been reached.  The
+	latter is used to copy a continuation stack at the right time.
+	scm_dowinds remains available.
+	(SCM_GUARDSP, SCM_BEFORE_GUARD, SCM_AFTER_GUARD, SCM_GUARD_DATA,
+	tc16_guard, guards_print): Removed.
+	(scm_internal_dynamic_wind): Reimplemented using frames.

+
+	* numbers.c (scm_less_p): Remove spurious xisnan from frac+big case.
+
+	* numbers.c (scm_make_ratio): Check for numerator equal to
+	SCM_MOST_NEGATIVE_FIXNUM and bignum denominator the negative of that,
+	giving integer -1.
+
+	* numbers.c (scm_real_part): Return fraction unchanged rather than
+	converting to flonum.
+
+2003-11-30  Dirk Herrmann  <D.Herrmann@tu-bs.de>
+
+	* modules.c (module_variable): Fixed (and thus simplified) the
+	definition of SCM_BOUND_THING_P to reflect the fact that since
+	after the 1.4 series of guile, obarrays only hold variable
+	objects.
+
+2003-11-30  Marius Vollmer  <mvo@zagadka.de>
+
+	* numbers.c (scm_logand): It's "#b...", not "#\b...".
+
+	From Paul Jarc:
+

+2003-11-22  Dirk Herrmann  <D.Herrmann@tu-bs.de>
+
+	* eval.c (s_bad_define): New static identifier.
+
+	(m_body): Fixed comment.
+
+	(scm_m_define): Don't generate memoized code for definitions that
+	are not on the top level.  As a consequence, no memoized code at
+	all is generated for definitions any more: Top level definitions
+	are executed immediately during memoization and internal
+	definitions are handled separately in m_expand_body.
+
+	(scm_unmemocopy, unmemocopy): Removed code for unmemoizing
+	definitions.  Consequently, there is no unmemoizing code any more
+	that might modify the environment.  Thus, the old scm_unmemocopy
+	is removed and the old unmemocopy is renamed to scm_unmemocopy.
+
+	(SCM_CEVAL): The SCM_IM_DEFINE keyword can no longer occur in
+	memoized code.  Call EVALCAR for continuations.  Prefer !SCM_NULLP
+	over SCM_NIMP in places, where the argument is known to be part of
+	a proper list.
+
+2003-11-21  Kevin Ryde  <user42@zip.com.au>
+
+	* numbers.c (scm_abs): Allocate a new real only for negatives, as done
+	for bignums.
+
+	* numbers.c (scm_bit_extract): Use mpz functions, rearrange inum case
+	to share some shifting.
+
+	* numbers.c (scm_integer_expt): Don't mpz_init after scm_i_clonebig or
+	scm_i_mkbig, since they do so already.  Don't mpz_clear a bignum SCM,
+	since gc does this.
+
+2003-11-19  Marius Vollmer  <mvo@zagadka.de>
+
+	* numbers.c (scm_make_ratio): Rewritten to have a simpler
+	structure.  Previously, not all cases with a negative denominator
+	were covered.
+
+	* numbers.c (mem2decimal_from_point): use scm_divide instead of
+	scm_divide2real when forming the fractional part.  This allows
+	"#e1.2" to yield 6/5.
+
+	* numbers.c (scm_i_fraction_equalp): Do not treat the return value
+	of scm_equal_p as a C boolean, use SCM_FALSEP.  Previously, all
+	fractions were equal to each other regardless of value.  Ooops.
+
+	* numbers.c (scm_rationalize): Return an inexact result when given
+	inexact arguments.
+
+	* numbers.c (scm_exact_p, scm_inexact_p): Throw error for

+
+	* eq.c (scm_eqv_p, scm_equal_p): Handle fractions.
+
+2003-11-18  Rob Browning  <rlb@defaultvalue.org>
+
+	* gen-scmconfig.c (main): remove public definition of
+	SCM_SIZEOF___INT64 and SCM_SIZEOF_UNSIGNED___INT64 and add
+	direct typedef of long_long and ulong_long inside deprecated block
+	when appropriate.
+
+	* deprecated.h: move long_long and ulong_long definitions to
+	gen-scmconfig.c so that we don't need to add SCM_SIZEOF___INT64
+	and SCM_SIZEOF_UNSIGNED___INT64 to the public namespace.

+	the "-e" option instead of scm_str2symbol.  This allows things
+	like (@ ...) to be specified for the entry point.
+
+2003-11-16  Dirk Herrmann  <D.Herrmann@tu-bs.de>
+
+	* eval.c (scm_m_letstar): Create memoized code in place to

+	unmemoization the quotes are added again to provide syntactically
+	correct code.

+
+2003-10-07  Marius Vollmer  <mvo@zagadka.de>
+
+ 	* goops.c, objects.h, smob.c, smob.h: Make type names char

+
+2003-10-02  Kevin Ryde  <user42@zip.com.au>
+
+	* strports.c (scm_call_with_output_string): scm_get_output_string
+	rather than scm_strport_to_string, so as to guard against the port
+	having been closed by the called procedure.  Reported by Nic Ferrier.
+
+2003-09-18  Dirk Herrmann  <D.Herrmann@tu-bs.de>
+
+	* numbers.h (SCM_INEXACTP): Removed uses of SCM_TYP16S.
+
+	* tags.h, deprecated.h (SCM_TYP16S): Deprecated and moved from
+	tags.h to deprecated.h.
+
+2003-09-18  Dirk Herrmann  <D.Herrmann@tu-bs.de>
+
+	This set of patches introduces a new tc7 code scm_tc7_number for
+	numbers.  Bignums, reals and complex numbers are turned from smobs
+	into subtypes of scm_tc7_number.
+
+	* tags.h (scm_tc7_number): New.
+
+	* eq.c (scm_equal_p), eval.c (SCM_CEVAL), evalext.c
+	(scm_self_evaluating_p), gc-card.c (scm_i_sweep_card), gc-mark.c
+	(scm_gc_mark_dependencies), goops.c (create_smob_classes), hash.c
+	(scm_hasher), numbers.c, numbers.h (SCM_NUMP), objects.c
+	(scm_class_of), print.c (scm_iprin1), smob.c
+	(scm_smob_prehistory): Don't handle bignums, reals and complex
+	numbers as subtypes of scm_tc7_smob any more.
+
+	* numbers.h, tags.h (scm_tc16_big, scm_tc16_real,
+	scm_tc16_complex): Moved definitions from tags.h to numbers.h.
+
+2003-09-18  Dirk Herrmann  <D.Herrmann@tu-bs.de>
+
+	* numbers.c (scm_make_complex), gc-card.c (scm_i_sweep_card): Use
+	sizeof (scm_t_complex) to determine the memory size of the
+	malloc'd area for complex numbers.
+
+2003-09-17  Dirk Herrmann  <D.Herrmann@tu-bs.de>
+
+	* numbers.c (scm_bigequal): Fixed.
+
+2003-09-16  Marius Vollmer  <mvo@zagadka.de>
+
+	* stime.c (scm_current_time): 'time' does not set errno so don't
+	use SCM_SYSERROR for reporting errors.
+
+2003-09-16  Dirk Herrmann  <D.Herrmann@tu-bs.de>
+
+	This set of patches eliminates the dependency between the
+	implementation of evaluator specific memoization codes and special
+	constants like #f, '() etc. ('flags'), which are not evaluator
+	specific.  The goal is to remove definitions of evaluator
+	memoization codes completely from the public interface.  This will
+	make it possible to experiment more freely with optimizations of
+	guile's internal representation of memoized code.
+
+	* objects.c (scm_class_of): Eliminate dependency on SCM_ISYMNUM.
+
+	* print.c (iflagnames): New array, holding the printed names of
+	guile's special constants ('flags').
+
+	(scm_isymnames): Now holds only the printed names of the
+	memoization codes.
+
+	(scm_iprin1): Separate the handling of memoization codes and
+	guile's special constants.
+
+	* tags.h (scm_tc9_flag, SCM_ITAG9, SCM_MAKE_ITAG9, SCM_ITAG9_DATA,
+	SCM_IFLAGNUM): new
+
+	(scm_tc8_char, scm_tc8_iloc, SCM_BOOL_F, SCM_BOOL_T,
+	SCM_UNDEFINED, SCM_EOF_VAL, SCM_EOL, SCM_UNSPECIFIED, SCM_UNBOUND,
+	SCM_ELISP_NIL, SCM_IM_DISPATCH, SCM_IM_SLOT_REF,
+	SCM_IM_SLOT_SET_X, SCM_IM_DELAY, SCM_IM_FUTURE,
+	SCM_IM_CALL_WITH_VALUES, SCM_IM_NIL_COND, SCM_IM_BIND): Changed
+	values.
+
+	(SCM_IFLAGP): SCM_IFLAGP now only tests for flags.
+
+	(SCM_IFLAGP, SCM_MAKIFLAG, SCM_IFLAGNUM): Generalized to use the
+	tc9 macros and scm_tc9_flag.
+
+2003-09-15  Marius Vollmer  <mvo@zagadka.de>
+
+	* posix.c (scm_setgroups): Check that the gid list is not too
+	long.  Thanks to Paul Jarc!
+
+2003-09-14  Dirk Herrmann  <D.Herrmann@tu-bs.de>
+
+	* tags.h: Reduced the number of short instructions from 14 to 13.
+	The typecode of the former 14th short instruction is now used to
+	represent long instructions.  Changed some comments to reflect
+	this fact.
+
+	(SCM_MAKISYM): ISYMs get a new tc7 code, namely the one that was
+	previously used by SCM_IM_DEFINE.
+
+	(SCM_IM_DEFINE): Turned into a long instruction.
+
+	* eval.c (unmemocopy, SCM_CEVAL): Treat SCM_IM_DEFINE as a long
+	instruction.
+
+	* eval.c (SCM_CEVAL): Since characters and iflags have now a tc7
+	code that is separate from all instructions, one level of dispatch
+	for long instructions can be eliminated.
+
+	* print.c (scm_isymnames): Removed some commented code.
+
+2003-09-12  Marius Vollmer  <mvo@zagadka.de>
+
+	* __scm.h (SCM_FENCE): Use __memory_barrier with the Intel
+	compiler on IA64.
+
+	* hashtab.h (scm_tc16_hashtable): Added "extern" declaration.
+
+	* modules.c (scm_module_reverse_lookup): Check that the obarray
+	really is a hashtable and do nothing if not.
+
+	* inline.h: Use "extern inline" only with GCC.  Use "static
+	inline" else.
+
+2003-09-06  Dirk Herrmann  <D.Herrmann@tu-bs.de>
+
+	* numbers.h (SCM_INEXACTP, SCM_REALP, SCM_COMPLEXP): Removed uses
+	of SCM_SLOPPY_INEXACTP, SCM_SLOPPY_REALP and SCM_SLOPPY_COMPLEXP.
+
+	* numbers.h, deprecated.h (SCM_SLOPPY_INEXACTP, SCM_SLOPPY_REALP,
+	SCM_SLOPPY_COMPLEXP): Deprecated and moved from numbers.h to
+	deprecated.h.
+
+2003-09-06  Dirk Herrmann  <D.Herrmann@tu-bs.de>
+
+	* eq.c (scm_eqv_p, scm_equal_p): Removed uses of
+	SCM_SLOPPY_INEXACTP, SCM_SLOPPY_REALP and SCM_SLOPPY_COMPLEXP.
+
+	* eq.c (scm_eqv_p, scm_equal_p): Reordered comparisons from
+	0.0==some_expression to some_expression==0.0.  The latter is
+	better readable.  The former is preferred by some people, since it
+	leads to a compiler error when confusing == with =.  However, when
+	using gcc, a warning will be issued if in an if-statement an
+	assigment appears.  Since many Guile developers are using gcc,
+	such errors will not remain unnoticed anyway.  We can therefore
+	focus on better readability.
+
+2003-09-04  Dirk Herrmann  <D.Herrmann@tu-bs.de>
+
+	* tags.h: Added description of Guile's type system.  Removed some
+	old and misleading comments.
+
+2003-09-04  Dirk Herrmann  <D.Herrmann@tu-bs.de>
+
+	* unit.c (scm_cvref): Eliminate unnecessary uses of SCM_NIMP,
+	SCM_SLOPPY_REALP and SCM_SLOPPY_COMPLEXP.
+
+2003-09-04  Dirk Herrmann  <D.Herrmann@tu-bs.de>
+
+	* numbers.h (SCM_MAKINUM): Define in terms of scm_tc2_int.
+
+	(SCM_INEXACTP, SCM_REALP, SCM_COMPLEXP): Define in terms of the
+	respective SLOPPY macro.
+
+2003-09-04  Dirk Herrmann  <D.Herrmann@tu-bs.de>
+
+	* eq.c (scm_equal_p): Use SCM_TYP7 to check if an object is of
+	type string, not SCM_TYP7S.
+
+2003-09-03  Kevin Ryde  <user42@zip.com.au>
+
+	* numbers.c (scm_lognot): Correction to docstring, ones-complement not
+	2s-complement.
+
+	* stime.c (scm_strptime): Add comment about glibc strptime %s and
+	current timezone requiring SCM_DEFER_INTS.
+
+2003-08-30  Neil Jerram  <neil@ossau.uklinux.net>
+
+	* script.c (scm_compile_shell_switches): Make -s switch optional
+	if file to be loaded does not begin with a `-'.  (Thanks to Aaron
+	VanDevender for the patch!)
+
+2003-08-30  Kevin Ryde  <user42@zip.com.au>
+
+	* numbers.c (scm_lognot): Rewrite using ~ and mpz_com, for directness
+	and to have non-integer types rejected as per other logical funcs.
+
+2003-08-28  Kevin Ryde  <user42@zip.com.au>
+
+	* gc.h (scm_remember_upto_here_1): Revise comments on the asm form.
+
+2003-08-23  Kevin Ryde  <user42@zip.com.au>
+
+	* simpos.c (scm_system): Remove SCM_DEFER_INTS, system() should be
+	thread safe, and could take a long time too.
+
+2003-08-22  Kevin Ryde  <user42@zip.com.au>
+
+	* numbers.c (scm_difference): Correction to bignum - negative inum.
+
+2003-08-14  Kevin Ryde  <user42@zip.com.au>
+
+	* gc.h (scm_remember_upto_here_1, scm_remember_upto_here_2)
+	[__GNUC__]: Use volatile asm macros rather than a function call.
+	* gc.c (scm_remember_upto_here_1, scm_remember_upto_here_2): Undefine
+	macros while defining functions.
+
+	* simpos.c (getenv): Use <stdlib.h> for prototype.
+	(scm_system): In docstring, refer to status:exit-val rather than

+
+	* srcprop.c (scm_source_properties): Return plist from hash if it's a
+	list set by source-properties! rather than an SRCPROPS object,
+
+2003-07-29  Kevin Ryde  <user42@zip.com.au>
+
+	* properties.c (scm_primitive_property_ref): In docstring, note
+	parameters to not-found-proc, use hyphens rather than underscores for
+	that parameter name.
+	(scm_primitive_property_set_x): In docstring, VAL is the value
+	parameter not CODE.
+
+2003-07-27  Marius Vollmer  <mvo@zagadka.de>
+
+	* print.c (scm_print_symbol_name): handle more weird characters by
+	escaping the symbol name properly.  Thanks to Paul Jarc!
+
+	* posix.h (scm_setgroups): New prototype.
+	* posix.c (scm_setgroups): New.  Thanks to Paul Jarc!
+	(scm_getgroups): Handle groups ids that don't fit into a fixnum.
+	Don't use SCM_WRITABLE_VELTS.
+
+	* gc.h (SCM_GC_SET_CELL_BVEC): New.
+	* gc-card.c (scm_i_init_card_freelist): Use it.  Thanks to
+	Matthias Koeppe!
+
+	* __scm.h (SCM_C_INLINE_KEYWORD): New.
+	* numbers.c: Use it in place of SCM_C_INLINE so that the code
+	compiles when SCM_C_INLINE is undefined.
+
+2003-07-24  Dirk Herrmann  <D.Herrmann@tu-bs.de>
+
+	* __scm.h: Reformulated the architecture and compiler properties
+	in terms of properties of scm_t_bits and SCM variables rather than
+	in terms of c standard types.  This is since it is not known which
+	of the standard types scm_t_bits and SCM variables will be defined
+	to.
+
+2003-07-24  Kevin Ryde  <user42@zip.com.au>
+

+	and a positive inum.
+	Use GNU indentation style.
+
+2003-07-12  Dirk Herrmann  <D.Herrmann@tu-bs.de>
+
+	* values.c (scm_values): Build lists of length 1 by using
+	scm_list_1 instead of using scm_cons.
+
+2003-07-10  Kevin Ryde  <user42@zip.com.au>
+

+
+	* gc-malloc.c (decrease_mtrigger): new function
+	(increase_mtrigger): new function, separate debug registering and
+	mtrigger administration.
+	(scm_gc_realloc): bugfix: do mtrigger administration before the
+	actual realloc, for the realloc might invalidate a GC-d segment of
+	memory. Thanks to Sam Hocevar for pointing this out.
+	(scm_gc_realloc): use scm_malloc_reregister instead of
+	unregistering and registering in sequence.
+
+2003-07-03  Han-Wen Nienhuys  <hanwen@cs.uu.nl>

+	* tags.h (scm_tcs_cons_imcar, scm_tcs_cons_nimcar, scm_tcs_struct,
+	scm_tcs_closures): Hard coded values replaced by symbolic ones.
+
+2003-06-05  Dirk Herrmann  <D.Herrmann@tu-bs.de>
+
+	* eval.c: Partially undid my patch from 2003-05-31.  This patch
+	caused the segfault referenced in the previous changelog entry.
+
+2003-06-05  Dirk Herrmann  <D.Herrmann@tu-bs.de>
+
+	* tags.h: Fixed comment about the immediate type code layout.
+
+	* eval.c: Fixed handling of non-special instructions.  Without
+	this patch, guile will segfault on (#\0) and similar instructions.
+
+2003-06-05  Kevin Ryde  <user42@zip.com.au>
+
+	* numbers.c (scm_max, scm_min): For inum, bignum and real, if other
+	operand is NaN, then return NaN.  Also avoid passing NaN to mpz_cmp_d.
+
+	* read.c (scm_input_error): Pass arg list parameter to scm_error_scm,
+	rather than SCM_EOL.  Needed by "Unknown # object" case in scm_lreadr.
+
+2003-06-04  Dirk Herrmann  <D.Herrmann@tu-bs.de>
+
+	* __scm.h, gc-card.c (SCM_DEBUG_DEBUGGER_SUPPORT,
+	SCM_DEBUG_DEBUGGING_SUPPORT): Renamed macro
+	SCM_DEBUG_DEBUGGER_SUPPORT to SCM_DEBUG_DEBUGGING_SUPPORT and
+	generalized it to apply not only to C level functions but also to
+	scheme level functions.
+
+	* debug.c, debug.h, eval.c (make-iloc, scm_make_iloc, iloc?,
+	scm_iloc_p, dbg-make-iloc, scm_dbg_make_iloc, dbg-iloc?,
+	scm_dbg_iloc_p): Moved functions scm_make_iloc, scm_iloc_p to
+	eval.c, made them available under SCM_DEBUG_DEBUGGING_SUPPORT == 1
+	only and renamed them to scm_dbg_make_iloc, scm_dbg_iloc_p,
+	respectively.
+
+	* deprecated.h, eval.c, eval.h (SCM_ILOC00, SCM_IDINC,
+	SCM_IDSTMSK): Deprecated.  The macro definitions are moved from
+	eval.h into eval.c and a copy is placed into deprecated.h.
+
+	* eval.c, eval.h (SCM_MAKE_ILOC): Removed from eval.h and placed
+	into eval.c. This definition was not part of the API in any
+	officially released version of guile and thus does not need to go
+	through a phase of deprecation.
+
+2003-06-02  Dirk Herrmann  <D.Herrmann@tu-bs.de>
+
+	* deprecated.c, deprecated.h, eval.c, eval.h (scm_s_expression,
+	scm_s_test, scm_s_body, scm_s_bindings, scm_s_variable,
+	scm_s_clauses, scm_s_formals): Deprecated.  In eval.c the
+	definitions are make static and renamed from scm_s_xxx to s_xxx.
+	In deprecated.c the original definitions are copied.
+
+	* deprecated.h, eval.c, eval (SCM_EVALIM2, SCM_EVALIM, SCM_XEVAL,
+	SCM_XEVALCAR): Deprecated.  The macro definitions are moved from
+	eval.h into eval.c and a copy (slightly modified to work in user
+	code) is placed into deprecated.h.
+
+	* eval.c: Use the local static s_xxx definitions instead of the
+	scm_s_xxx definitions throughout.

+
+	This set of patches separates the representation of the cxr family
+	of functions (car, cdr etc.) from the dsubr family of functions
+	(i. e. functions that take a double precision floating point
+	argument).  Further, the algorithm for handling the cxr function
+	is improved.
+
+	* eval.c (SCM_CEVAL, SCM_APPLY, scm_trampoline_1), numbers.c
+	(scm_asinh, scm_acosh, scm_atanh, scm_truncate, scm_round, floor,
+	ceil, sqrt, fabs, exp, log, sin, cos, tan, asin, acos, atan, sinh,

+	(scm_i_procedure_arity), ramap.c (scm_array_map_x), tags.h
+	(scm_tc7_dsubr, scm_tcs_subrs): Introduce scm_tc7_dsubr as new
+	typecode for the dsubr family of functions.
+
+	* ramap.c (ramap_cxr, ramap_dsubr): Renamed ramap_cxr to
+	ramap_dsubr.
+
+	* eval.c (SCM_CEVAL, SCM_APPLY, call_cxr_1), pairs.c
+	(scm_init_pairs): Make use of the (now usable) second cell element
+	of a scm_tc7_cxr function to implement the cxr family of functions
+	more efficiently.
+
+2003-05-31  Dirk Herrmann  <D.Herrmann@tu-bs.de>
+
+	* eval.c (SCM_CEVAL, SCM_APPLY, scm_trampoline_0,
+	scm_trampoline_1, scm_trampoline_2): Postpone error cases to the
+	end of an if-else-if-sequence of checks.
+
+2003-05-30  Dirk Herrmann  <D.Herrmann@tu-bs.de>
+
+	* eval.c (SCM_CEVAL): Improved readability of call-with-values
+	execution.  Generalize apply_closure to apply_proc and use that
+	for call-with-values.
+
+2003-05-30  Dirk Herrmann  <D.Herrmann@tu-bs.de>
+
+	* eval.c (SCM_CEVAL): Avoid one level of indirection when applying
+	a non closure.
+
+2003-05-30  Stefan Jahn  <stefan@lkcc.org>
+
+	* posix.c (s_scm_putenv): Use the new HAVE_UNSETENV
+	appropriately for mingw32 hosts.
+
+	* numbers.h: Defining copysign(), isnan() and finite() to
+	be prefixed by a single '_' for mingw32 hosts.
+
+2003-05-30  Kevin Ryde  <user42@zip.com.au>
+
+	* numbers.c (z_negative_one): New variable.
+	(scm_init_numbers): Initialize it.
+	(scm_logcount): Use it and mpz_hamdist to count zeros for negatives.
+
+2003-05-29  Stefan Jahn  <stefan@lkcc.org>
+
+	* win32-dirent.c: Use malloc() instead of scm_malloc().
+
+	* stime.c (s_scm_strftime): Add a type cast to avoid compiler
+	warning.
+
+	* posix.c (s_scm_putenv): Disable use of unsetenv() for the
+	mingw32 build.
+
+	* modules.c (s_scm_module_import_interface): Renamed local
+	variable interface to _interface.  Seems like 'interface'
+	is a special compiler directive for the mingw32 compiler.
+
+	* mkstemp.c: Provide prototype to avoid compiler warning.
+
+	* load.c (s_scm_search_path): Fixed absolute and relative
+	path detections for native Windows platforms.
+
+	* gc.h, threads.h: Export some more symbols using SCM_API (necessary
+	to build on mingw32).
+
+	* gc-freelist.c ("s_scm_map_free_list",

+
+2003-05-25  Dirk Herrmann  <D.Herrmann@tu-bs.de>

+	always being false by inserting preprocessor conditional.  (Thanks
+	to Bruce Korb.)
+
+	* __scm.h (SCM_STACK_PTR): New macro. (Cast argument through
+	(void *) in order to avoid an aliasing warning; thanks to Bruce
+	Korb.)
+
+	* stackchk.h (SCM_STACK_OVERFLOW_P): Use SCM_STACK_PTR.
+
+	* threads.c (suspend, launch_thread, scm_threads_mark_stacks): Use

+
+	* eval.c (SCM_CEVAL): Don't cast argument of SCM_STACK_OVERFLOW_P.

+
+2003-05-19  Dirk Herrmann  <D.Herrmann@tu-bs.de>
+
+	* eval.c (scm_m_do, unmemocopy, SCM_CEVAL):  Reversed order of

+	a compilation error if error-on-warning is enabled).
+
+2003-05-17  Marius Vollmer  <mvo@zagadka.de>
+
+	* c-tokenize.lex: Gobble up complete lines after a '#'.  This
+	removes preprocessor directives from the snarfage that might
+	otherwise confuse us.  These directives appear when compiling with
+	"-g3", for example.
+
+2003-05-16  Han-Wen Nienhuys  <hanwen@cs.uu.nl>

+
+	* numbers.c (scm_gcd): In bignum/inum, don't pass yy==0 to mpz_gcd_ui

+
+2003-05-06  Dirk Herrmann  <D.Herrmann@tu-bs.de>
+
+	* eval.c, eval.h, read.c, read.h (scm_sym_dot): Moved from eval to

+
+2003-05-06  Dirk Herrmann  <D.Herrmann@tu-bs.de>
+
+	* eval.c, eval.h, evalext.c, evalext.h (scm_m_undefine): Moved

+
+2003-05-06  Kevin Ryde  <user42@zip.com.au>
+
+	* numbers.c (scm_difference): In inum - bignum, handle negative inum.

+
+2003-05-04  Dirk Herrmann  <D.Herrmann@tu-bs.de>
+
+	The purpose of this patch is to make guile's internal memoizers
+	distinguishable from memoizing macros created on the scheme level
+	or from user provided primitive memoizing macros.  The reason is,
+	that the internal memoizers are the only ones that are allowed to
+	transform their scheme input into memoizer byte code, while all
+	other memoizing macros may only transform scheme code into new
+	scheme code.
+
+	To achieve this, a new macro type 'builtin-macro!' is introduced.
+	Currently, 'builtin-macro!'s are handled as memoizing macros, but
+	this will change when the memoizer and executor are separated.
+
+	* macros.[ch] (scm_i_makbimacro): New.
+
+	* macros.h (SCM_BUILTIN_MACRO_P): New.
+
+	* macros.c (macro_print, scm_macro_type): Support builtin-macro!s.
+
+	* eval.c, goops.c: All of guile's primitive memoizing macros are
+	primitive builtin-macros now.
+
+	* eval.c (scm_macroexp, SCM_CEVAL): Make sure the primitive
+	builtin-macros are handled equally to memoizing macros.
+
+2003-05-04  Marius Vollmer  <mvo@zagadka.de>
+
+	* throw.c (scm_ithrow): Remove "asm volatile" hack.  It used to
+	work around a bug in GCC 2.95.2 but is now a bug in itself.
+
+2003-05-02  Marius Vollmer  <mvo@zagadka.de>
+
+	* deprecated.h (scm_rstate, scm_rng, SCM_SLOPPY_CONSP,
+	SCM_SLOPPY_NCONSP, scm_tc7_ssymbol, scm_tc7_msymbol,
+	scm_tcs_symbols): New.

+	* ports.h (scm_c_port_for_each): New prototype.
+
+2003-04-28  Mikael Djurfeldt  <djurfeldt@nada.kth.se>
+
+	* eval.c (scm_m_atdispatch): Removed until actually needed.  (This
+	macro was introduced in anticipation of GOOPS method compilation
+	code.)
+
+	* goops.c: Removed binding of @dispatch.
+
+2003-04-28  Dirk Herrmann  <D.Herrmann@tu-bs.de>
+
+	* eval.c, goops.c (@dispatch, @slot-ref, @slot-set!): Move the
+	instructions that bind the macros on the scheme level back to
+	goops.c in order to make sure again that the bindings go into the
+	(oop goops) module and are not visible from the outside.
+
+2003-04-27  Dirk Herrmann  <D.Herrmann@tu-bs.de>
+
+	* eval.c: Non functional change: Separated R5RS and non-R5RS

+2003-04-27  Dirk Herrmann  <D.Herrmann@tu-bs.de>
+
+	* eval.c (scm_ilookup):  Rewritten to improve readability.

+
+	* eval.c (scm_i_call_closure_0, call_closure_1, call_closure_2):
+	Partially reverted patch from 2003-04-23 in oder to find a better
+	compromise between readability and debuggability.
+
+2003-04-25  Dirk Herrmann  <D.Herrmann@tu-bs.de>
+
+	* eval.c, eval.h, goops.c, goops.h (scm_m_atslot_ref,
+	scm_m_atslot_set_x, scm_m_atdispatch): Move the declarations and
+	definitions of the special goops memoizers from goops.[ch] to
+	eval.[ch].  Hmm... it seems that scm_m_atdispatch is not used
+	throughout guile.
+
+2003-04-24  Mikael Djurfeldt  <mdj@kvast.blakulla.net>
+
+	* ports.c, ports.h (scm_i_port_table_mutex): New mutex.

+
+2003-04-23  Dirk Herrmann  <D.Herrmann@tu-bs.de>
+
+	This set of patches contains no functional changes, only debatable
+	minor stylistic ones.  Still, in order to prepare a patch between
+	my local copy and the CVS version, I decided to submit the changes
+	below.  Then, the patch will hopefully only contain relevant
+	modifications :-)
+
+	* eval.c (iqq): Added const specifier.
+
+	* eval.c (scm_trampoline_0, scm_trampoline_1, scm_trampoline_2):
+	Use NULL instead of 0 to indicate that a pointer is returned.
+	Removed some misleading 'fall through' comments.
+

+	Split up long expressions into smaller ones to be more debugging
+	friendly.

+
+2003-04-23  Dirk Herrmann  <D.Herrmann@tu-bs.de>

+	cmp_fun_t): Removed.
+
+	(compare_function): Added.
+
+	* sort.c (quicksort, SWAP, stack_node): Replaced pointer
+	arithmetics with index arithmetics.  Changed quicksort to work on
+	an array of SCM values instead of an array of characters.  Avoid

+	stack with alloca.  Fixed some comments.
+
+2003-04-21  Dirk Herrmann  <D.Herrmann@tu-bs.de>
+
+	* eval.c (EXTEND_ENV): Eliminated.
+
+	(unmemocopy, SCM_CEVAL, SCM_APPLY): Use SCM_EXTEND_ENV instead of

+	functions such that they check if the object is a non-immediate.
+	Further, renamed identifiers to use the scm_dbg_ prefix and made
+	their inclusion into the lib dependent of the
+	SCM_DEBUG_DEBUGGER_SUPPORT compile time option.
+
+2003-04-21  Dirk Herrmann  <D.Herrmann@tu-bs.de>

+	scm_m_generalized_set_x, scm_init_evalext): Move the declaration
+	and definition of the memoizer for the generalized set! macro from

+
+	This fixes a serious GC bug, introduced during the latest
+	reorganization of the GC, which disabled freeing of structs and
+	GOOPS objects:
+
+	* struct.c (scm_struct_prehistory): Init scm_i_structs_to_free to
+	SCM_EOL.
+	(scm_struct_prehistory): Move scm_free_structs to
+	scm_before_mark_c_hook.
+
+	* gc-card.c (sweep_card): Check that we haven't swept structs on
+	this card before.  That can happen if scm_i_sweep_all_segments has
+	been called from some other place than scm_igc.
+
+2003-02-19  Mikael Djurfeldt  <djurfeldt@nada.kth.se>
+
+	* environments.c (DEFAULT_OBARRAY_SIZE): Changed from 137 to 31
+	(since hash tables now adapt their size).
+
+	* modules.c (scm_modules_prehistory): Changed from 2001 to 1533
+	(current number of prehistory bindings; hashtable code will select
+	a prime which is greater than this value).
+
+	* symbols.c (scm_symbols_prehistory): Changed from 1009 to 2139
+	(current number of initial symbols).
+
+	* properties.c (scm_init_properties): Don't specify size of
+	scm_properties_whash.

+
+	The following changes introduce the use of resizable hash tables
+	throughout Guile.  It also renames the old *-hash-table* functions
+	to *-alist-vector* and places them, together with the rest of the
+	weak vector support, in the module (ice-9 weak-vector).  We should
+	probably introduce a new, better, API for weak references, for
+	example "weak pairs" a la MIT-Scheme.  (In Chez scheme, they even
+	look like and are used like ordinary pairs.)
+
+	* environments.c (obarray_enter, obarray_retrieve, obarray_remove,
+	leaf_environment_fold, obarray_remove_all): Use hashtable

+	scm_make_doubly_weak_alist_vector): New functions.
+
+	* weaks.c (scm_init_weaks_builtins): New function.
+
+	* weaks.h (SCM_WVECTF_WEAK_KEY, SCM_WVECTF_WEAK_VALUE,
+	SCM_WVECTF_NOSCAN, SCM_WVECT_WEAK_KEY_P, SCM_WVECT_WEAK_VALUE_P,
+	SCM_WVECT_NOSCAN_P): New macros.
+
+	* weaks.c (scm_scan_weak_vectors):  Use SCM_WVECT_WEAK_KEY_P
+	and SCM_WVECT_WEAK_VALUE_P.
+
+	* weaks.c, weaks.h (scm_i_allocate_weak_vector): Renamed from
+	allocate_weak_vector and exported.
+
+2003-02-13  Mikael Djurfeldt  <djurfeldt@nada.kth.se>
+
+	* hashtab.c: Undid thread safety.  (We decided that it's better to
+	let the user explicitly protect the tables (or not) according what
+	is suitable for the application.)
+
+2003-02-12  Mikael Djurfeldt  <djurfeldt@nada.kth.se>
+
+	* hashtab.c (scm_hash_fn_remove_x, scm_internal_hash_fold): Made
+	thread safe and handle resizing tables.
+	(scm_ihashx, scm_sloppy_assx, scm_delx_x): Removed
+	SCM_DEFER/ALLOW_INTS.
+
+2003-02-11  Mikael Djurfeldt  <djurfeldt@nada.kth.se>

+
+2003-01-23  Mikael Djurfeldt  <djurfeldt@nada.kth.se>
+
+	* futures.c (mark_futures): Don't need to mark data of recycled
+	futures.
+	(scan_futures, cleanup_undead): Be smarter about marking
+	futures---avoid unnecessary passes through future lists.
+
+	* futures.h, futures.c: New files; Introduced recycling of
+	futures.  For fine-grained threading this lifts performance to

+
+2002-12-21  Mikael Djurfeldt  <djurfeldt@nada.kth.se>
+
+	This change makes it possible for one thread to do lazy sweeping
+	while other threads are running.  Now only the mark phase need to
+	have all threads asleep.  We should look further into this issue.
+	Presently, I've put the locking of scm_i_sweep_mutex at
+	"conservative" places due to my current lack of knowledge about
+	the garbage collector.  Please feel free to restrict these regions
+	further to allow for maximal parallelism!
+
+	* gc.c, gc.h (scm_i_sweep_mutex): New mutex.
+
+	* gc.c (scm_gc_for_newcell), gc-malloc.c (scm_realloc,
+	scm_gc_register_collectable_memory): Substitute locking of

+	scm_i_thread_put_to_sleep/scm_i_thread_wake_up used to demarkate
+	the single-thread section (which now only contains the mark

+	(scm_gc): Don't lock sweeo mutex here since scm_igc locks it;

+	(scm_force): Rewritten;  Now thread-safe; Removed
+	SCM_DEFER/ALLOW_INTS.

+	* threads.c: Conditionally #include "pthread-threads.c".
+
+	* eval.c, eval.h (scm_makprom, scm_force): Rewritten to be
+	thread-safe;
+
+	* snarf.h (SCM_MUTEX, SCM_GLOBAL_MUTEX, SCM_REC_MUTEX,
+	SCM_GLOBAL_REC_MUTEX): New macros.
+
+	* eval.c, threads.c, threads.h, snarf.h: Rewrote critical section
+	macros---use mutexes instead.

+2002-12-10  Mikael Djurfeldt  <mdj@kvast.blakulla.net>
+
+	* Makefile.am (c-tokenize.$(OBJEXT)): Don't look for c-tokenize.c
+	in srcdir.
+
+2002-12-10  Mikael Djurfeldt  <djurfeldt@nada.kth.se>
+
+	These changes remove scm_ints_disabled (which hasn't has any
+	effect in Guile for quite some time).
+
+	* async.c, error.h (scm_ints_disabled): Removed.
+
+	* gc.c (scm_gc_for_newcell), init.c (scm_init_guile_1),
+	root.c (scm_internal_cwdr), gdbint.c (SCM_BEGIN_FOREIGN_BLOCK,
+	SCM_END_FOREIGN_BLOCK): Don't touch scm_ints_disabled.
+	(old_ints): Removed.
+
+	* __scm.h (SCM_DEFER_INTS, SCM_ALLOW_INTS): Define as a recursive
+	critical section.
+	(SCM_REDEFER_INTS, SCM_ALLOW_INTS): Define as SCM_DEFER_INTS and
+	SCM_ALLOW_INTS.
+
+2002-12-09  Mikael Djurfeldt  <djurfeldt@nada.kth.se>
+
+	* threads.c (scm_mutex_lock, scm_cond_wait, scm_cond_timedwait):
+	Removed accidental #if 0 around these functions.
+
+	These changes are the start of support for preemptive
+	multithreading.  Marius and I have agreed that I commit this code
+	into the repository although it isn't thoroughly tested and surely
+	introduces many bugs.  The bugs should only be exposed when using
+	threads, though.  Signalling and error handling for threads is
+	very likely broken.  Work on making the implementation cleaner and
+	more efficient is needed.
+
+	* __scm.h (SCM_ALLOW_INTS_ONLY): Removed.
+	(SCM_NONREC_CRITICAL_SECTION_START,
+	SCM_NONREC_CRITICAL_SECTION_END, SCM_REC_CRITICAL_SECTION_START,
+	SCM_REC_CRITICAL_SECTION_END): New macros.
+	(SCM_CRITICAL_SECTION_START/END): Defined here.
+
+	* eval.c: Insert SOURCE_SECTION_START / SOURCE_SECTION_END around
+	the three calls to scm_m_expand_body.
+
+	* gc.h: #include "libguile/pthread-threads.h";
+	(SCM_FREELIST_CREATE, SCM_FREELIST_LOC): New macros.
+
+	* gc.c (scm_i_freelist, scm_i_freelist2): Defined to be of type
+	scm_t_key;
+
+	* gc.c, gc-freelist.c, inline.h: Use SCM_FREELIST_LOC for freelist
+	access.
+
+	* gc-freelist.c (scm_gc_init_freelist): Create freelist keys.
+
+	* gc-freelist.c, threads.c (really_launch): Use
+	SCM_FREELIST_CREATE.
+
+	* gc-malloc.c (scm_realloc, scm_gc_register_collectable_memory):
+
+	* gc.c (scm_i_expensive_validation_check, scm_gc,
+	scm_gc_for_newcell): Put threads to sleep before doing GC-related
+	heap administration so that those pieces of code are executed
+	single-threaded.  We might consider rewriting these code sections
+	in terms of a "call_gc_code_singly_threaded" construct instead of
+	calling the pair of scm_i_thread_put_to_sleep () and
+	scm_i_thread_wake_up ().  Also, we would want to have as many of
+	these sections eleminated.
+
+	* init.c (scm_init_guile_1): Call scm_threads_prehistory.
+
+	* inline.h: #include "libguile/threads.h"
+
+	* pthread-threads.h: Macros now conform more closely to the
+	pthreads interface.  Some of them now take a second argument.
+
+	* threads.c, threads.h: Many changes.
+
+2002-12-09  Mikael Djurfeldt  <djurfeldt@nada.kth.se>
+
+	* Makefile.am (version.h): Changed $^ --> $< in rule for
+	version.h.
+
+2002-12-08  Rob Browning  <rlb@defaultvalue.org>
+
+	* version.h.in (SCM_MICRO_VERSION): use @--@ substitution now.
+	(SCM_MINOR_VERSION): use @--@ substitution now.
+	(SCM_MICRO_VERSION): use @--@ substitution now.
+	(scm_effective_version): new function prototype.
+
+	* version.c (scm_effective_version): new function, also add
+	effective-version.
+
+	* Makefile.am (schemelibdir): VERSION -> GUILE_EFFECTIVE_VERSION.
+	(libpath.h): use GUILE_EFFECTIVE_VERSION to compute
+	SCM_LIBRARY_DIR.
+	(version.h): generate this here rather than configure.in.  This
+	approach tracks source edits better (i.e. more immediately).
+	Might be worth considering for other .in files too.
+
+2002-12-02  Marius Vollmer  <mvo@zagadka.ping.de>
+
+	Reorganized thread package selection.  A thread package now only
+	implements a small set of pthread like functions and Guile
+	implements the rest on top of that.  Guile's implementation is
+	what the "coop-pthreads" package has been previously.  Support for
+	"coop" threads has been removed until I get time to add it again.
+
+	* Makefile.am (libguile_la_SOURCES): Removed iselect.c.
+	(noinst_HEADERS): Removed coop-threads.c, coop-threads.h, coop.c,
+	null-threads.c, coop-pthreads.c.
+	(modinclude_HEADERS): Removed coop-defs.h, coop-pthreads.h.  Added
+	pthread-threads.h.
+
+	* validate.h (SCM_VALIDATE_THREAD): Moved to threads.h.
+
+	* threads.h: Do not include "libguile/coop-defs.h".  Include
+	"libguile/pthread-threads.h" for USE_COPT_THREADS.  Removed
+	(previously deprecated) C level thread API prototypes.  They are
+	now in the thread package specific headers, "null-threads.h" and
+	"pthread-threads.h".
+	(SCM_VALIDATE_THREAD, SCM_VALIDATE_MUTEX, SCM_VALIDATE_CONDVAR):
+	New.
+	(scm_threads_init): Removed.
+	(SCM_CRITICAL_SECTION_START, SCM_CRITICAL_SECTION_END,
+	SCM_THREAD_SWITCHING_CODE, scm_i_switch_counter,
+	SCM_I_THREAD_SWITCH_COUNT): Define here.
+	(scm_single_thread_p): Removed.
+	(scm_call_with_new_thread): Take two args directly instead of list
+	of two args.
+	(scm_i_thread_data, scm_i_set_thread_data, SCM_THREAD_LOCAL_DATA,
+	SCM_SET_THREAD_LOCAL_DATA): Define here.
+
+	* threads.c: Merged with "coop-pthreads.c".
+
+	* null-threads.h: Implement pthread-like API as a set of macros.
+
+	* pthread-threads.h: New, implement pthread-like API by deferring
+	to pthread itself.
+
+	* init.c (scm_init_guile_1): Do not call scm_init_iselect, which
+	has been lost in the reorganization.
+
+2002-12-01  Mikael Djurfeldt  <mdj@linnaeus>
+
+	The following change makes it possible to move procedure
+	application dispatch outside inner loops.  The motivation was
+	clean implementation of efficient replacements of R5RS primitives
+	in SRFI-1.
+
+	The semantics is clear: scm_trampoline_N returns an optimized
+	version of scm_call_N (or NULL if the procedure isn't applicable
+	on N args).
+
+	Applying the optimization to map and for-each increases efficiency
+	noticeably.  For example, (map abs ls) is 8 times faster than
+	before.
+
+	* eval.h (scm_t_trampoline_1, scm_t_trampoline_2): New types.
+
+	* eval.c, eval.h (scm_trampoline_1, scm_trampoline_2): New functions.
+
+	* eval.c (call_subr2_2, call_lsubr_2, call_closure_2): New functions;
+	(map, for-each): Handle also application on two args as a special
+	case; Use trampolines.
+
+	Other changes:
+
+	* sort.c (scm_cmp_function): Choose subr2less for scm_tc7_subr_2o;
+	(subr2oless): Removed.
+	(scm_restricted_vector_sort_x): Use scm_return_first to keep the
+	vector GC protected.
+
+	* eval.c (check_map_args): Use scm_out_of_range_pos instead of
+	scm_out_of_range.
+
+2002-11-24  Dirk Herrmann  <D.Herrmann@tu-bs.de>
+
+	* evalext.[ch] (scm_m_undefine, undefine):  Deprecated.
+
+2002-11-17  Mikael Djurfeldt  <mdj@linnaeus>
+
+	* debug.c (scm_make_iloc): Added missing "return".
+
+2002-11-17  Marius Vollmer  <mvo@zagadka.ping.de>
+
+	* strports.c (scm_eval_string_in_module): Validate second arg to
+	be a module.  Thanks to Arno Peters!
+
+2002-11-16  Dirk Herrmann  <D.Herrmann@tu-bs.de>
+
+	* .cvsignore: remove goops.c
+
+2002-11-16  Dirk Herrmann  <D.Herrmann@tu-bs.de>
+
+	* modules.c (scm_env_top_level, scm_lookup_closure_module,
+	module_variable, scm_module_lookup_closure,
+	scm_module_transformer, scm_sym2var, scm_module_reverse_lookup,
+	scm_system_module_env_p):  Don't compare SCM values with C
+	operators == or !=.  Avoid SCM_IMP predicates.  Prefer !SCM_FALSEP
+	over SCM_NFALSEP.
+
+2002-11-16  Dirk Herrmann  <D.Herrmann@tu-bs.de>
+
+	* eval.h (SCM_MAKE_ILOC):  New macro.
+
+	* debug.c (scm_make_iloc):  Use SCM_MAKE_ILOC instead of computing
+	the iloc bitpattern here.
+
+2002-11-14  Mikael Djurfeldt  <mdj@linnaeus>
+
+	* coop-pthreads.c, coop-pthreads.h: scm_internal_select should be
+	part of the API, otherwise it's difficult to write Guile
+	extensions using non-blocking I/O => moved #include
+	"libguile/iselect.h" from coop-pthreads.c --> coop-pthreads.h.
+
+	* coop-pthreads.c (scm_unlock_mutex): Changed s_lock_mutex -->
+	s_unlock_mutex.
+
+2002-11-10  Marius Vollmer  <mvo@zagadka.ping.de>
+
+	* __scm.h (USE_THREADS, GUILE_ISELECT): Do not define here.  They
+	are defined in configure.in.
+
+	* threads.c: Removed SCM_API from function definitions.  SCM_API
+	is only for declarations.
+
+2002-11-07  Mikael Djurfeldt  <mdj@linnaeus>
+
+	* coop-pthreads.h: Added support for thread specific data to the
+	generic C API for the coop-pthreads case.
+
+	* threads.c, threads.h (scm_cond_init): Undo unintentional API
+	change.
+	(scm_cond_broadcast): Added missing function.
+
+2002-11-04  Marius Vollmer  <marius.vollmer@uni-dortmund.de>
+
+	* coop.c (coop_next_runnable_thread): Removed, wich should have
+	happened when GUILE_ISELECT was hard-wired.

+
+	* Makefile.am (libguile_la_SOURCES): Added threads.c

+	(modinclude_HEADERS): Added coop-pthreads.h.
+
+	* __scm.h (USE_THREADS, GUILE_ISELECT): Define when
+	SCM_DEBUG_DEPRECATED.  Removed their use thru-out Guile.
+
+	* iselect.c: Include "_scm.h" before testing HAVE_UNISTD_H.
+	Thanks to Bill Schottstaedt!
+
+	* numbers.c (scm_integer_expt): Make 0^z == 0 for z != 0.
+
+	* _scm.h (HAVE_RESTARTABLE_SYSCALLS): Do define even when
+	SCM_COPT_THREADS is defined.
+	(SCM_SYSCALL): Use EINTR-expection version when SCM_COPT_THREADS
+	is defined.
+
+	* coop-pthreads.c: Some harmless renamings of internal stuff.
+	(create_thread): New, generalized version of
+	scm_call_with_new_thread.
+	(scm_call_with_new_thread): Use it.
+	(scm_spawn_thread): New, use create_thread.
+
+2002-11-02  Marius Vollmer  <mvo@zagadka.ping.de>
+
+	* coop-pthreads.c, coop-pthreads.h: Redone completely, you might
+	start testing it now.
+
+	* _scm.h: Include <errno.h< so that SCM_SYSCALL is correctly
+	defined when HAVE_RESTARTABLE_SYSCALLS is not defined.
+	(HAVE_RESTARTABLE_SYSCALLS): Do not define when USE_COPT_THREADS
+	is defined.
+
+2002-10-27  Marius Vollmer  <mvo@zagadka.ping.de>
+
+	* scmsigs.c (signal_cell_handlers, install_handler_data,
+	scm_delq_spine_x, really_install_handler, install_handler): New
+	scheme for triggering signal handlers, to simplify take_signal.
+	(take_signal): Simplified, to avoid race conditions.
+	(scm_sigaction_for_thread): Use new Scheme.  Validate that thread
+	hasn't exited yet.
+
+	* async.c (scm_async_click): Reset pending_asyncs, handle
+	signal_asyncs.  Don't set cdr of a non-signal async to #f.
+	(scm_i_queue_async_cell): Do not check cdr of cell for #f, queue
+	always.  Set pending_asyncs.
+	(scm_system_async_mark_for_thread): Check that thread has not
+	exited.
+	(scm_unmask_signals, decrease_block): Call scm_async_click after
+	block_asyncs becomes zero.
+
+	* __scm.h (SCM_ASYNC_CLICK): Check pending_asyncs instead of
+	active_asyncs.
+
+	* root.h (scm_root_state): Added pending_asyncs and signal_asyncs
+	fields.
+	* root.c (root_mark): Mark them.
+	(make_root): Initialize them.
+
+	* iselect.c, iselect.h: Replaced GUILE_ISELECT with

+	one for USE_NULL_THREADS.
+	(scm_init_iselect): Likewise.
+
+        * inline.h (scm_cell, scm_double_cell): Also allow
+	USE_COPT_THREADS to not protect the slot initializers.
+
+	* init.c (scm_init_guile_1): Call scm_init_thread_procs.  This is
+	because threads need to be initialized before the stack, but
+	gsubrs such as scm_timed_condition_variable_wait can only be
+	created later.
+
+	* threads.h: Include "coop-pthreads.h" when requested.
+	(scm_threads_make_mutex, scm_threads_lock_mutex,

+	registered procedures.
+	(scm_wait_condition_variable, scm_timed_wait_condition_variable):
+	Use the latter as the procedure for "wait-condition-variable",
+	thus offering a optional timeout parameter to Scheme.
+	(scm_wait_condition_variable): Implement in terms of
+	scm_timed_wait_condition_variable.
+	(scm_mutex_init, scm_mutex_lock, scm_mutex_trylock,

+	scm_cond_broadcast, scm_cond_destroy): Implement in terms of
+	scm_make_mutex, etc, and deprecate.
+	(scm_init_threads): Do not create smobs, leave this to
+	scm_threads_init.  Do not include "threads.x" file.
+	(scm_init_thread_procs): New, include "threads.x" here.
+
+	* null-threads.h (scm_null_mutex, scm_null_mutex_init,

+
+	* null-threads.c (scm_null_mutex, scm_null_cond): Define here.
+	(scm_threads_init): Create smobs here, using the appropriate
+	sizes.

+	scm_null_mutex_destroy, scm_null_condvar_init,
+	scm_null_condvar_wait, scm_null_condvar_signal,
+	scm_null_condvar_destroy): Removed and updated users to do their
+	task directly.
+	(scm_try_mutex, timeval_subtract,
+	scm_timed_wait_condition_variable,
+	scm_broadcast_condition_variable): New.
+	(scm_wait_condition_variable): Removed.
+
+	* coop-defs.h (coop_m): Added 'level' field.

+
+	* goops.c (hell_mutex): Reimplemented using scm_make_mutex, etc.
+
+	* coop-pthreads.h, coop-pthreads.c: New, but unfinished.

+
+2002-10-19  Dirk Herrmann  <D.Herrmann@tu-bs.de>
+
+	* evalext.h, evalext.c (scm_definedp, scm_defined_p):  Renamed

+
+2002-10-15  Marius Vollmer  <mvo@zagadka.ping.de>
+
+	* Makefile.am: Replaced "$<" in non-pattern rules with its value.
+	This is to support makes that know about "$<" only in pattern
+	rules, like Sun's make.
+
+2002-10-13  Marius Vollmer  <mvo@zagadka.ping.de>
+
+	* Makefile.am (libpath.h): Fixed typo in top_srcdir_absolute

+	otherwise.
+
+	* scmsigs.c (take_signal): Only call scm_i_thread_root when
+	USE_THREADS is defined.  Use scm_root otherwise.
+	(scm_sigaction_for_thread): Ignore THREAD argument when

+	out of HAVE_SIGACTION section, which was a bug.
+
+2002-10-10  Marius Vollmer  <marius.vollmer@uni-dortmund.de>
+
+	* scmsigs.c (scm_sigaction_for_thread): Store original handler in
+	signal_handlers, not the closure that is used as the async.
+	The closure is stored in signal_handler_cells, as previously.
+
+2002-10-10  Marius Vollmer  <mvo@zagadka.ping.de>
+
+	* root.h (scm_root_state): Added 'block_async' slot.

+	this should not be necessary.
+	(scm_async_click): Test block_asyncs instead of scm_mask_ints.
+	(scm_mask_signals, scm_unmask_signals): Deprecated.  Emit
+	deprecation warning and check for errornous use.  Set block_asyncs
+	instead of scm_mask_ints.
+	(increase_block, decrease_block, scm_call_with_blocked_asyncs,
+	scm_call_with_unblocked_asyncs, scm_c_call_with_blocked_asyncs,

+	extended to also set the thread of a signal and allocate a cell
+	for it.  Keep the Scheme name "sigaction".  Check that signum is
+	within range.  Also, use SCM_VECTOR_REF instead of SCM_VELTS.
+	(scm_sigaction): Implement in terms of scm_sigaction_for_thread.
+	(scm_init_scmsigs): Allocate signal_handler_cells and
+	signal_handler_threads vectors.
+

+
+2002-08-25  Han-Wen Nienhuys  <hanwen@cs.uu.nl>
+
+	* gc-segment.c (scm_i_get_new_heap_segment): use float in stead of
+	unsigned numbers for computing minimum heap increment. This
+	prevents weird results when a a negative minimum increment is
+	computed.
+
+2002-08-24  Marius Vollmer  <mvo@zagadka.ping.de>
+
+	* gc_os_dep.c: When we have __libc_stack_end, use that directly
+	instead of the old tricks.
+
+	* guile-snarf.in: Do not expect the input file to be the first
+	argument after the optional "-o" option, just pass everything to
+	the pre-processor without extracting the input file name.
+
+2002-08-23  Han-Wen Nienhuys  <hanwen@cs.uu.nl>
+
+	* gc-segment.c (scm_i_get_new_heap_segment): Oops. We want segment

+	message and abort.
+
+	* gc-mark.c ("scm_gc_mark_dependencies"): idem.
+
+	* ports.c ("scm_new_port_table_entry"): return a boxed SCM in

+
+2002-08-04  Han-Wen Nienhuys <hanwen@cs.uu.nl>
+
+	* ports.c (scm_new_port_table_entry): init port entry to 0
+	completely.
+
+	* ports.c (scm_new_port_table_entry): change function from
+	scm_add_to_port_table. This prevents cells with null-pointers from
+	being exposed to GC.
+
+	* vports.c (scm_make_soft_port) strports.c (scm_mkstrport),
+	fports.c (scm_fdes_to_port): Use scm_new_port_table_entry().
+
+	* gc.c (scm_gc_stats): add cell-yield and malloc-yield statistic

+
+2002-07-24  Stefan Jahn  <stefan@lkcc.org>
+
+	* continuations.h: ia64: Include <signal.h> before
+	<sys/ucontext.h>.
+
+2002-07-21  Dirk Herrmann  <D.Herrmann@tu-bs.de>
+
+	* modules.c (scm_sym2var):  Don't compare SCM values with ==.
+
+2002-07-21  Han-Wen Nienhuys <hanwen@cs.uu.nl>
+
+	* goops.c (scm_compute_applicable_methods): use

+
+	* macros.c: include deprecation.h
+
+	* vectors.c (scm_vector_move_right_x): remove side effect in

+
+	* net_db.c, posix.c, socket.c: variable naming: change ans to

+
+	* sort.c (scm_merge_vector_x): accept vector as argument
+	iso. SCM*. This is needed for full GC correctness.
+
+	* gc.h: undo previous undocumented changes related to #ifdef

+
+2002-07-20  Han-Wen Nienhuys <hanwen@cs.uu.nl>
+
+	* *.c: add space after commas everywhere.
+
+	* *.c: use SCM_VECTOR_SET everywhere, where a vector is written.
+	Document cases where SCM_WRITABLE_VELTS() is used.
+
+	* vectors.h (SCM_VELTS): prepare for write barrier, and let
+	SCM_VELTS() return a const pointer
+	(SCM_VECTOR_SET): add macro.
+
+2002-07-15  Dirk Herrmann  <D.Herrmann@tu-bs.de>
+
+	* eval.c (SCM_CEVAL), macros.c (macro_print, scm_makmacro,
+	scm_sym_macro, scm_macro_type), macros.h (scm_makmacro):
+	Deprecated the special kind of built-in dynamic syntax transformer
+	that was inaccurately named "macro".  Note:  The built-in syntax
+	transformers that are named "mmacro" or "memoizing-macro" still
+	exist, and it is these which come much closer to what one would
+	call a macro.
+
+2002-07-13  Neil Jerram  <neil@ossau.uklinux.net>
+
+	* eval.c (unmemocopy): Fix for
+	1001-local-eval-error-backtrace-segfaults (unmemoization crash
+	with internal definitions and local-eval).
+
+2002-07-12  Gary Houston  <ghouston@arglist.com>
+
+	* dynl.c: Don't define stub procedures if DYNAMIC_LINKING is not
+	defined.  They don't do anything useful, especially since the
+	only case where DYNAMIC_LINKING is undefined seems to be
+	when --with-modules=no is given to configure, which is basically
+	requesting that the "dynamic linking module" be omitted.
+
+	* Makefile.am (libguile_la_SOURCES): move dynl.c from
+	libguile_la_SOURCES to EXTRA_libguile_la_SOURCES.
+
+	* extensions.c (load_extension): check DYNAMIC_LINKING for
+	scm_dynamic_call.
+	* init.c (scm_init_guile_1): check DYNAMIC_LINKING for
+	scm_init_dynamic_linking.
+
+2002-07-10  Marius Vollmer  <mvo@zagadka.ping.de>
+
+	* guile.c, iselect.h, net_db.c, posix.c, socket.c: No need to
+	check for Cygwin when including <winsock2.h>, this is already
+	check for by configure.  Thus, revert change from 2002-07-07.
+
+2002-07-10  Gary Houston  <ghouston@arglist.com>
+
+	* eq.c: include <string.h>
+	* dynl.c: docstring editing.
+
+2002-07-09  Gary Houston  <ghouston@arglist.com>
+
+	* dynl.c (scm_dynamic_call): docstring editing.
+
+2002-07-08  Rob Browning  <rlb@defaultvalue.org>
+
+	* gc_os_dep.c: HURD fixes.
+
+2002-07-07  Marius Vollmer  <mvo@zagadka.ping.de>
+
+	Crosscompiling and Cygwin fixes by Jan Nieuwenhuizen.  Thanks!
+
+	* Makefile.am: Override default rule for c-tokenize.$(OBJECT);
+	this should be compiled for BUILD host.
+	Override default rule for
+	guile_filter_doc_snarfage$(EEXECT); this should run on BUILD host.
+	Add missing $(EXEEXT) to guile_filter_doc_snarfage invocation.
+	(snarf2checkedtexi): Use GUILE_FOR_BUILD instead of preinstguile.
+
+	* guile.c, iselect.h, net_db.c, posix.c, socket.c: Do not include
+	<winsock2.h> on Cygwin even when we have it.
+
+2002-07-01  Dirk Herrmann  <D.Herrmann@tu-bs.de>
+
+	* __scm.h (SCM_CAUTIOUS), eval.c (scm_eval_args, deval_args,
+	SCM_CEVAL):  Removed compile time option SCM_CAUTIOUS to clean up
+	the code.  Full number of arguments checking of closures is
+	mandatory now.  However, the option to disable the checking has
+	most probably not been used anyway.
+
+2002-06-30  Dirk Herrmann  <D.Herrmann@tu-bs.de>
+
+	* __scm.h (SCM_RECKLESS), backtrace.c (SCM_ASSERT), debug.c
+	(scm_debug_options), eval.c (scm_lookupcar, scm_lookupcar1,
+	scm_badargsp, SCM_CEVAL, SCM_APPLY, scm_map, scm_for_each),
+	feature.c (scm_init_feature), gsubr.c (scm_gsubr_apply), numbers.c
+	(scm_logand, scm_logior, scm_logxor, scm_i_dbl2big), srcprop.c
+	(scm_source_properties, scm_set_source_properties_x,
+	scm_source_property):  Removed compile time option SCM_RECKLESS to
+	clean up the code.  Full number of arguments checking of closures
+	is mandatory now.  However, the option to disable the checking has
+	most probably not been used anyway.
+
+	* srcprop.c (scm_source_properties, scm_set_source_properties_x,
+	scm_source_property): Use !SCM_CONSP instead of SCM_NCONSP.
+
+2002-06-30  Gary Houston  <ghouston@arglist.com>
+
+	* dynl.c: Removed all SCM_DEFER_INTS/SCM_ALLOW_INTS, which won't
+	do anything useful.  Added a comment about need for a mutex if
+	pre-emptive threading is supported.
+
+	* posix.c (scm_convert_exec_args), dynl.c
+	(scm_make_argv_from_stringlist): static procs: 1) renamed both to
+	allocate_string_pointers.  2) simplified: don't reallocate the
+	strings, just make an array of pointers 3) avoid memory leaks on
+	error 4) let the procedure report errors in its own name.
+	Consequences: 1) the procedures now assume that SCM strings are
+	nul-terminated, which should always be the case.  2) Since strings
+	are not reallocated, it's now possible for strings passed to
+	dynamic-args-call to be mutated.
+
+2002-06-28  Dirk Herrmann  <D.Herrmann@tu-bs.de>
+
+	* __scm.h, eval.c, eval.h:  Removed compile time option
+	MEMOIZE_LOCALS to clean up the code.  Now, caching of local
+	variable positions during memoization is mandatory.  However, the
+	option to disable the caching has most probably not been used
+	anyway.
+
+2002-06-18  Marius Vollmer  <mvo@zagadka.ping.de>
+
+	* print.c (scm_simple_format): Print missing part of format before
+	~% control.  Thanks to Daniel Skarda!

+
+	* mkstemp.c: Added exception notice to license statement.
+
+2002-05-22  Marius Vollmer  <mvo@zagadka.ping.de>
+
+	* numbers.c (mem2ureal): When returning an inexact zero, make sure
+	it is represented as a floating point value so that we can change
+	its sign.
+
+        From John W. Eaton  <jwe@bevo.che.wisc.edu>
+
+	* numbers.c (idbl2str): Don't omit sign when printing negative zero.
+
+2002-05-14  Thien-Thi Nguyen  <ttn@giblet.glug.org>
+
+	* gc_os_dep.c: For I386/OPENBSD, allow for `__i386__'
+	in addition to `i386'.  Thanks to Dale P. Smith.
+
+2002-05-08  Marius Vollmer  <mvo@zagadka.ping.de>
+

+	calling unsetenv.
+
+	From John W. Eaton.
+

+	(scm_inf, scm_nan): New functions.
+	(idbl2str): Handle Inf and NaN.	Remove funny label and
+	corresponding gotos.
+	(ALLOW_DIVIDE_BY_ZERO): New macro.
+	(scm_divide): Allow division by zero to occur if
+	ALLOW_DIVIDE_BY_ZERO is defined.
+	Handle bignums and ints as special cases.
+
+	Additional stuff by me:
+
+	numbers.c (mem2ureal): Recognize "inf.0" and "nan.xxx".
+	(scm_even_p, scm_odd_p): Treat infinity as even and odd.
+	(iflo2str): Don't output a '+' for negative numbers or for Inf and
+	NaN.  They will provide their own sign.
+	(scm_divide): Only allow divides by inexact zeros.  Dividing by
+	exact zeros still signals an errors.
+
+2002-04-22  Thien-Thi Nguyen  <ttn@giblet.glug.org>
+
+	* goops.h (scm_slot_exists_p): Rename from scm_slots_exists_p.
+	* goops.c (scm_slot_exists_p): Rename from scm_slots_exists_p.
+	(scm_slot_exists_p): Rename from scm_slots_exists_p.
+	Thanks to Andreas Rottmann.
+
+2002-04-20  Gary Houston  <ghouston@arglist.com>
+
+	* removal of unused fields in root state (thanks to Christopher
+	Cramer for pointing out the disuse.)
+	* root.h (scm_root_state): removed def_inp, def_outp, def_errp.
+	(scm_def_inp, scm_def_outp, scm_def_errp): removed.
+
+	* root.c (root_mark): don't mark them.

+
+2002-04-16  Marius Vollmer  <mvo@zagadka.ping.de>
+

+	the $(srcdir) during a VPATH build, which is not allowed.  It also
+	isn't needed since it only works when an output filename has been
+	specified and in that case we don't need to clean the input file

+	the preprocessor macro SCM_MAGIC_SNARFER while snarfing.
+
+	* Makefile.am (.c.x): Pass "-o $@" to guile-snarf.

+	spelling mistakes.
+
+	* debug.c (scm_debug_options), eval.c
+	(scm_eval_options_interface), read.c (scm_read_options): Change
+	incorrect @var in docstring to @code.

+	SCM_IM_T_IFY, SCM_IM_0_COND, SCM_IM_0_IFY, SCM_IM_1_IFY.
+
+	* lang.c (scm_nil_cons, scm_nil_car, scm_nil_cdr, scm_null,
+	scm_m_while, scm_nil_eq): Commented out; I don't think we need

+
+2001-11-21  Gary Houston  <ghouston@arglist.com>

+
+2001-11-22  Dirk Herrmann  <D.Herrmann@tu-bs.de>
+

+
+2001-11-20  Marius Vollmer  <mvo@zagadka.ping.de>
+
+	* modules.c (scm_c_export): Do nothing when the first argument is

+
+2001-11-20  Thien-Thi Nguyen  <ttn@glug.org>
+

+
+	* eval.c:  Removed bogus comment about acros.
+
+	(scm_unmemocar):  Use !SCM_CONSP instead of SCM_IMP.
+	Minimize scope of local variable.  Eliminate dependency on

+
+	(scm_m_letrec1):  Removed.  Part of the functionality is taken
+	over by the new function 'transform_bindings'.
+

+	functionality of removed function 'scm_m_letrec1', namely to split
+	a list of bindings into a reversed list of variables and a list of
+	initializers.
+
+	(scm_m_letrec):  Call 'transform_bindings'.
+
+	(scm_m_let):  Minimized scope of local variables.  Renamed 'proc'
+	to 'temp' and 'arg1' to 'binding'.  Eliminated redundant SCM_NIMP
+	test.  Use 'transform_bindings'.  Fixed scoping error with named

+	Jerram for suggesting the fix).  Cleaned up the control structure
+	a bit.
+
+	(scm_m_expand_body):  Use 'transform_bindings'.  Eliminated
+	unnecessary consing.  Eliminated unnecessary
+	SCM_DEFER/ALLOW_INTS.
+

+	version.c, alist.c, ports.c, ramap.c, unif.c, strings.c, list.c:
+	Change @deffnx lines in docstrings to say {Scheme Procedure}
+	rather than primitive or procedure.
+
+	* posix.c (scm_execl), filesys.c (scm_close), unif.c
+	(scm_array_set_x, scm_array_contents, scm_uniform_array_read_x,

+	made in the reference manual source.
+
+	* objprop.c (scm_object_properties, scm_set_object_properties_x,
+	scm_object_property, scm_set_object_property_x): Remove invalid
+	@deffnx lines for corresponding procedure property primitives.
+
+	These changes add a @deffnx C function declaration and function
+	index entries for each Guile primitive to the copy of the doc
+	snarf output that is used for reference manual synchronization.
+	Online help is unchanged.
+
+	* snarf.h (SCM_SNARF_DOCS): Output primitive's C function name.
+	(SCM_DEFINE, SCM_DEFINE1, SCM_REGISTER_PROC): Supply to C function
+	name to SCM_SNARF_DOCS.
+
+	* guile-snarf-docs-texi.in: Pass the shell script's arguments into
+	snarf-check-and-output-texi.
+
+	* Makefile.am (guile-procedures.texi): New rule.
+	(BUILT_SOURCES, guile.texi, guile-procedures.txt, CLEANFILES):
+	Changed so that the last stage of doc snarfing is now performed
+	twice, once to produce guile-procedures.txt for online help, and
+	once to produce guile.texi for reference manual synchronization.
+
+2001-11-15  Dirk Herrmann  <D.Herrmann@tu-bs.de>
+
+	* eval.c (RETURN):  Wrap in do{}while(0) in order to make it
+	safely usable as a single statement followed by a ';', for example
+	in an if statement.
+
+	(SCM_CEVAL, SCM_APPLY):  Clean up code using 'RETURN'.
+
+2001-11-13  Neil Jerram  <neil@ossau.uklinux.net>

+	HAVE_LONG_LONGS): Define to "1" when defining them, to mirror what
+	configure does.
+
+2001-11-12  Marius Vollmer  <mvo@zagadka.ping.de>
+
+	* numbers.c: Document macros to define when including
+	num2integral.i.c.  MAX_VALUE and MIN_VALU are no longer used, we
+	now rely on SIZEOF_ macros that have been figured out at
+	configure time.
+
+	* num2integral.i.c: Adapt to new interface.
+	(NUM2INTEGRAL): Test whether a fixnum can be represented in the
+	target type by casting it and checking whether it is still the
+	same.  Do not try to handle bignums for integral types that are
+	smaller than fixnums.  When handling bignums, collect the
+	magnituse first into a unsigned type, and correctly check for
+	overflow.
+	(INTEGRAL2BIG): Do not use MIN_VALUE explicitely by observing that
+	only -MIN_VALUE can still be negative of all negative numbers (in
+	twos-complement).
+
+	* tags.h (SIZEOF_SCM_T_BITS): Define it appropriately.
+
+	* __scm.h: Define HAVE_UINTPTR_T, HAVE_PTRDIFF_T and
+	HAVE_LONG_LONG depending on whether their size is non-zero.

+	newline at end of docstrings.
+
+	* modules.c (scm_set_current_module): Add missing newline to
+	docstring.
+
+2001-11-07  Stefan Jahn  <stefan@lkcc.org>
+
+	* win32-socket.[ch]: New files.  Defines Winsock-API error codes
+	and makes them available through Guile.  That is because the
+	Winsock-API does not store its errors in `errno' and thus cannot
+	return error messages via `strerror (errno)'.
+
+	* socket.c (scm_init_socket): Initialize `win32-socket' part
+	here under M$-Windows.
+
+	* numbers.h: Added missing declaration of
+	`scm_sys_check_number_conversions()'.
+
+	* error.c: Local definition of SCM_I_STRERROR and SCM_I_ERRNO
+	and use in `(strerror)' and `(system-error)'.
+
+	* Makefile.am (EXTRA_libguile_la_SOURCES): Added
+	`win32-socket.[ch]' to extra source and header files.
+
+2001-11-06  Marius Vollmer  <mvo@zagadka.ping.de>
+
+	* script.c (scm_shell_usage, scm_compile_shell_switches): Prepend
+	a call to turn-on-debugging when --debug has been given instead of
+	turning it on directly.  Also, handle new `--no-debug' option,
+	which might suppress the call to turn-on-debugging.
+
+2001-11-05  Stefan Jahn  <stefan@lkcc.org>
+
+	* struct.c (s_scm_struct_vtable_p): Corrected docstring.
+
+2001-11-04  Stefan Jahn  <stefan@lkcc.org>
+
+	* Makefile.am (libguile_la_LIBADD): Added $(THREAD_LIBS_LOCAL)
+	here (was at guile_LDADD) which describes the dependency
+	correctly and allows a clean build on Win32.
+
+	* __scm.h (SCM_API): Follow-up patch.  Renamed __FOO__ macros
+	into FOO.
+
+	* __scm.h: USE_DLL_IMPORT indicates the usage of the DLL
+	import macros for external libraries (libcrypt, libqthreads,
+	libreadline and libregex).
+
+	* coop-defs.h: Include <winsock2.h> for `struct timeval'.
+
+	* posix.c (flock): Added support for flock() in M$-Windows.
+
+	* guile.c (SCM_IMPORT): Follow-up patch.  Use SCM_IMPORT instead
+	of __SCM_IMPORT__.
+
+	* fports.c (getflags): Differentiate reading and writing pipes
+	descriptors.
+
+	* filesys.c (S_IS*): Redefine all of the S_IS*() macros for
+	M$-Windows.
+
+	* coop.c (coop_condition_variable_timed_wait_mutex): Use
+	conditionalized error code if `ETIMEDOUT' is not available.
+	(scm_thread_usleep): Remove bogus declaration of `struct timeval
+	timeout'.
+
+	* numbers.c (PTRDIFF_MIN): Moved this definition where it actually
+	belongs.  That is because NO_PREPRO_MAGIC gets undefined after
+	each inclusion of `num2integral.i.c'.
+	(SIZE_MAX): Define NO_PREPRO_MAGIC if SIZE_MAX is undefined.
+
+2001-11-03  Marius Vollmer  <mvo@zagadka.ping.de>
+
+	* eval.c (scm_m_begin): Allow `(begin)`, with no subforms.
+	(SCM_CEVAL): Evaluate an empty `begin' to SCM_UNSPECIFIED.
+
+2001-11-02  Mikael Djurfeldt  <mdj@linnaeus>
+
+	* print.c (scm_iprin1): Mark print state as revealed when
+	dispatching to generic write or display.
+
+	* unif.c (scm_ra2contig): Fixed memory overwrite bug.
+
+2001-11-02  Marius Vollmer  <mvo@zagadka.ping.de>
+
+	Support for native Win32.  Thanks to Stefan Jahn!
+
+        * Makefile.am: Add win32-uname.c, win32-uname.h, win32-dirent.c
+	and win32-dirent.h to extra source and header files.  These
+	include the uname() and the POSIX dirent interface implementation
+	for M$-Windows.  Put `-no-undefined' into LDFLAGS to support
+	linkers which do not allow unresolved symbols inside shared
+	libraries.  Corrected `guile_filter_doc_snarfage$(EXEEXT)'
+	dependency.
+
+        * __scm.h: Defined SCM_API.  This macro gets prepended to all
+        function and data definitions which should be exported or imported
+        in the resulting dynamic link library in the Win32 port.

+
+	(scm_m_case, scm_m_cond, scm_m_letstar, scm_m_do, SCM_CEVAL):  Use
+	!SCM_NULLP instead of SCM_NIMP.
+
+	(scm_m_case):  Don't copy the form.  Renamed proc to clause and
+	minimized its scope.  Renamed x to clauses.  Removed side
+	effecting operation from macro call.
+
+	(scm_m_cond):  Don't copy the form.  Renamed arg1 to clause and
+	minimized its scope.  Renamed x to clauses.  Minimized the scope
+	of variable 'len'.  Make sure the else clause is treated specially
+	even in case of '=>' occurences.  Don't change the else to #t in
+	order to be able to distinguish this case in the evaluator.  Leave
+	type checking of the recipient to the evaluator.
+
+	(scm_c_improper_memq):  Made the comment somewhat clearer.
+
+	(scm_m_lambda):  Renamed proc to formals.  Removed unnecessary
+	test for SCM_IM_LET at the place of the formal parameters.
+	Simplified the formal parameter checking.
+
+	(scm_m_letstar):  Added Comment.  Renamed proc to bindings.
+	Renamed arg1 to binding and minimized its scope.  Eliminated
+	unnecessary consing.
+
+	(scm_m_do):  Renamed proc to bindings.  Minimized the scope of
+	variable 'len'.
+
+	(build_binding_list):  New static function.
+
+	(unmemocopy):  Don't use SCM_TYP7 on pairs (it's unclean).
+	Further, split up the 'letrec' unmemoizing code to the
+	corresponding parts for 'do', 'let' and 'letrec', adding comments
+	to each form.  Cleanup the handling of the do form (This removes
+	some *real* code :-).
+
+	(SCM_CEVAL):  Removed side effecting operation from macro call.
+	Handle the 'else clause of the 'cond form specially - the symbol

+
+2001-10-14  Mikael Djurfeldt  <mdj@linnaeus>
+
+	* read.c (scm_lreadr): When user-defined hash procedure returns
+	SCM_UNSPECIFIED: Fall back to standard handling instead of raising
+	an exception.  (This prevents parsing of uniform vectors from
+	interfering with parsing of numbers.)
+
+2001-10-13  Marius Vollmer  <mvo@zagadka.ping.de>

+
+	* numbers.c (mem2uinteger):  Return number read so far when coming
+	across a hexdigit after having read a # or if not reading a hex
+	value.  This will enable the calling code to correctly handle

+
+	(scm_current_pstate, scm_make_print_state, scm_free_print_state,
+	scm_prin1, scm_init_print):  print_state_pool is registered as a

+	pair any more.
+
+	(make_print_state):  The car of print_state_pool no longer holds
+	the scm_print_state_vtable.
+
+	(scm_current_pstate, scm_make_print_state, print_circref,
+	scm_iprin1, scm_prin1, scm_iprlist):  Prefer !SCM_<foo> over

+
+	(scm_iprlist):  Removed a redundant SCM_IMP test.

+
+	(scm_procedure_name):  Use SCM_CADR instead of explicit form.
+
+	(debugobj_print):  Coerce scm_intprint arg 1 to long, not int.
+	Thanks to Rob Browning for the patch (see log entry 2001-09-21) -

+
+2001-10-09  Dirk Herrmann  <D.Herrmann@tu-bs.de>

+2001-10-08  Dirk Herrmann  <D.Herrmann@tu-bs.de>
+
+	* hashtab.c (scm_hash_fn_create_handle_x):  The result of assoc_fn
+	is known to be #f if no entry is found.  Thus, use !SCM_FALSEP
+	instead of SCM_NIMP to test for that case.
+
+	* strings.h (SCM_SET_STRING_LENGTH):  Cast the length to
+	scm_t_bits instead of long.
+
+2001-10-06  Marius Vollmer  <mvo@zagadka.ping.de>
+

+	* numbers.h (SCM_MOST_POSITIVE_FIXNUM, SCM_MOST_NEGATIVE_FIXNUM):
+	Use them to make these macros computable by the preprocessor.
+
+	* num2integral.i.c (INTEGRAL2NUM): Let the preprocessor test
+	whether the integral type fits in a fixnum, not the compiler.
+	This removes a spurious compiler warning.  Also, honor the
+	NO_PREPRO_MAGIC flag to suppress any preprocessor tests.  This is
+	needed for `long long's.
+
+	* numbers.c: Define NO_PREPRO_MAGOC when including
+	num2integral.c.i for `long long' and `signed long long'.
+
+2001-10-06  Mikael Djurfeldt  <mdj@linnaeus>
+
+	These changes fixes a race condition in the Guile coop - pthread
+	compatibility code.
+
+	* coop.c (mother_awake_p): New variable.

+	mother; wait until mother is going to sleep before returning.
+	(mother): Reset mother_awake_p before going to sleep.
+
+2001-10-05  Dirk Herrmann  <D.Herrmann@tu-bs.de>
+
+	* options.c (protected_objects, scm_init_options):  The content of
+	protected_objects is now protected from garbage collection using
+	scm_gc_register_root instead of scm_permanent_object.
+
+	(get_option_setting):  New static function that	computes an option
+	setting as it was formerly done in the function scm_options.
+
+	(get_documented_option_setting):  New static function that
+	returns option documentation as it was formerly done in the
+	function scm_options.  Note that documentation C strings are no
+	longer precomputed into SCM objects.  Instead, they are converted
+	into SCM strings every time get_documented_option_setting is
+	called.
+
+	(change_option_setting):  New static functions that modifies the
+	option setting as it was formerly done in the function
+	scm_options.  The function is now exception safe, i. e. won't
+	cause a memory leak when interrupted.  Further, only non-immediate
+	option values are added to the protection list.
+
+	(scm_options):  This function now has only the purpose to dispatch
+	to to get_option_setting, get_documented_option_setting or
+	change_option_setting, depending on the arguments given to
+	scm_options.
+
+	(scm_init_opts):  Don't convert documentation C strings into SCM
+	strings.  Further, don't protect any object values:  They _must_
+	be immediate values, otherwise there is no guarantee that they
+	have not been collected before anyway.
+
+	* options.[ch] (scm_t_option):  Made type unsigned, name into a
+	constant char* and val into a scm_t_bits type.
+
+	(scm_options, scm_init_opts):  The number of options is guaranteed
+	to be larger or equal to zero.  Thus, the type is changed to
+	unsigned.
+
+2001-10-05  Dirk Herrmann  <D.Herrmann@tu-bs.de>
+
+	* num2integral.i.c (NUM2INTEGRAL):  Eliminated some warnings about
+	testing an unsigned value for being >= 0.
+
+2001-10-05  Dirk Herrmann  <D.Herrmann@tu-bs.de>
+
+	* numbers.h:  Removed old comment about using SCM_CAR to access
+	non-pair cells.
+
+	(SCM_MOST_POSITIVE_FIXNUM, SCM_MOST_NEGATIVE_FIXNUM):  Make sure
+	the return value is signed.  Thanks to Brian Crowder for the bug
+	report.
+
+	(SCM_SRS):  Avoid unnecessary casting and don't unpack input
+	values.  With this patch, SCM_SRS can be safely used for other
+	types than scm_t_signed_bits.  However, it should still better be
+	an internal macro and thus be renamed to SCM_I_SRS.
+
+	(SCM_MAKINUM, SCM_INUM):  Use proper casting.
+
+2001-10-03  Gary Houston  <ghouston@arglist.com>
+
+	* continuations.h, unif.h: in the descriptions of the bit patterns
+	of the heap cells, make bit 0 the least significant.
+
+2001-09-25  Thien-Thi Nguyen  <ttn@glug.org>
+
+	* chars.h (SCM_MAKE_CHAR): Use `scm_t_bits' instead of `intptr_t'.
+	Thanks to Golubev I. N.
+
+2001-09-25  Gary Houston  <ghouston@arglist.com>
+
+	* ports.c (scm_drain_input): extended the docstring.  thanks to
+	Alex Schroeder and Thien-Thi Nguyen.
+
+2001-09-23  Mikael Djurfeldt  <mdj@linnaeus>
+
+	* validate.h (SCM_NUM2FLOAT, SCM_NUM2DOUBLE,
+	SCM_VALIDATE_FLOAT_COPY, SCM_VALIDATE_DOUBLE_COPY): New
+	macros. (The NUM names might soon change.)
+
+	* numbers.h: Added missing declarations.
+
+2001-09-22  Mikael Djurfeldt  <mdj@linnaeus>
+
+	* Makefile.am: Distribute num2float.i.c.
+
+	* num2float.i.c: New file, multiply included by numbers.c, used
+	to "templatize" the float <-> num conversion routines.
+
+	* numbers.c: New functions: scm_num2float, scm_float2num,
+	scm_num2double, scm_double2num.
+
+2001-09-21  Rob Browning  <rlb@defaultvalue.org>
+
+	* .cvsignore: really add version.h
+
+	* strings.h (SCM_SET_STRING_LENGTH): coerce "l" to a long.
+	Otherwise it fails on the alpha.  However, we might rather choose
+	this size conditionally.
+
+	* numbers.c (scm_gcd): change "k" to a long from an int.
+	Otherwise it fails on the alpha.  However, we might rather choose
+	this size conditionally.
+
+	* error.c (scm_wta): coerce char* to intptr_t before int
+	assignment.
+
+	* debug.c (debugobj_print): coerce scm_intprint arg 1 to long, not
+	int.
+
+	* chars.h (SCM_MAKE_CHAR): coerce value to intptr_t.
+
+2001-09-20  Mikael Djurfeldt  <mdj@linnaeus>
+
+	* numbers.c (scm_integer_expt): Accept inexact integer in second
+	argument.  (Thanks to Bill Schottstaedt.)
+
+2001-09-20  Rob Browning  <rlb@defaultvalue.org>
+
+	* .cvsignore: add version.h
+
+	* versiondat.h.in: removed (obsolete).
+
+	* version.h.in: renamed from version.h.
+	(SCM_GUILE_MAJOR_VERSION): new public macro.
+	(SCM_GUILE_MINOR_VERSION): new public macro.
+	(SCM_GUILE_MICRO_VERSION): new public macro.
+
+	* version.h: renamed to version.h.in.
+
+	* version.c
+	(scm_major_version): support integer *_VERSION macros.
+	(scm_minor_version): support integer *_VERSION macros.
+	(scm_micro_version): support integer *_VERSION macros.
+	(scm_version): support integer *_VERSION macros.
+
+2001-09-20  Mikael Djurfeldt  <mdj@linnaeus>
+
+	* error.c, error.h: Made error keys globally accessible.
+	Applications might want to test for these or use them in a direct
+	call to scm_error.
+
+	* num2integral.i.c (NUM2INTEGRAL): Report an error when these
+	routines are passed an inexact.  This change in behavior is
+	motivated by concordance with R5RS: It is more common that a
+	primitive doesn't want to accept an inexact for an exact.
+
+2001-09-17  Dirk Herrmann  <D.Herrmann@tu-bs.de>
+
+        The following patch partially undoes my patch from 2001-06-30,
+	where I added the function scm_gc_mark_cell_conservatively.  The
+	function is buggy, since it breaks guile during conservative
+	marking if a pointer on the stack points directly into the list of
+	free cells on the heap:  With conservative cell marking this will
+	cause the whole free list to be scanned and marked - boom!
+
+	* gc.c (allocated_mark, MARK, heap_segment,
+	scm_gc_mark_cell_conservatively, scm_init_storage), gc.h
+	(scm_gc_mark_cell_conservatively):  Remove function
+	scm_gc_mark_cell_conservatively and update the corresponding
+	comments and uses accordingly.  Thanks to Christopher Cramer for
+	the patch.  (Minor corrections by me.)
+
+2001-09-15  Gary Houston  <ghouston@arglist.com>
+
+	* root.h (scm_root_state): removed the continuation_stack and
+	continuation_stack_ptr members, which have no apparent purpose.
+	(scm_continuation_stack, scm_continuation_stack_ptr): #defines
+	removed.
+
+	* root.c (root_mark), init.c (restart_stack, start_stack), gc
+	(scm_igc): remove all references to contination_stack and
+	continuation_stack_ptr, avoiding allocation of a vector and
+	useless processing during gc.
+
+2001-09-13  Dirk Herrmann  <D.Herrmann@tu-bs.de>
+
+	* guardians.c (tconc_t, t_tconc):  Renamed tconc_t to t_tconc.
+
+	(TCONC_IN):  Make sure that the cell word 0 is initialized last.
+
+	(guardians_t, t_guardians):  Renamed guardians_t to t_guardians.
+
+	(GUARDIAN, GUARDIAN_DATA):  Renamed GUARDIAN to GUARDIAN_DATA.
+
+	(guardian_apply, scm_get_one_zombie, scm_make_guardian,
+	mark_and_zombify):  Prefer !SCM_<foo> over SCM_N<foo>.
+
+2001-09-13  Dirk Herrmann  <D.Herrmann@tu-bs.de>
+
+	* guardians.c (mark_dependencies_in_tconc,
+	whine_about_self_centered_zombies, scm_init_guardians):  Register
+	the static global variable `self_centered_zombies' via
+	scm_gc_register_root, to make some cdr-ing unnecessary.
+
+2001-09-13  Dirk Herrmann  <D.Herrmann@tu-bs.de>
+
+	* backtrace.c (display_backtrace_file,
+	display_backtrace_file_and_line):  Use SCM_EQ_P when comparing SCM
+	values, use SCM_FALSEP when comparing SCM values against #f.
+	Thanks to Rob Browning for the bug report.
+
+2001-09-12  Martin Baulig  <martin@home-of-linux.org>
+
+	* strings.[ch] (scm_str2string): New function.
+
+2001-09-06  Marius Vollmer  <mvo@zagadka.ping.de>
+
+	* gc.c (scm_done_free): Always subtract size from scm_mallocated
+	when computing nm, even if it's negative.
+	(scm_must_malloc): Abort on overflow of scm_mtrigger.
+	(scm_must_realloc): Likewise.
+
+2001-09-01  Michael Livshin  <mlivshin@bigfoot.com>
+
+	* numbers.c (scm_sys_check_number_conversions): new function,
+	defined if Guile is compiled in debugging mode.  currently checks
+	`scm_num2ulong', should check much much more.
+
+	* num2integral.i.c (NUM2INTEGRAL): when converting a bignum to
+	unsigned, ensure that it's positive.  thanks to Martin Baulig!
+
+2001-08-31  Dirk Herrmann  <D.Herrmann@tu-bs.de>
+
+	* __scm.h: Added new section about compile time selectable
+	features.
+
+	(long_long, ulong_long, scm_sizet, SCM_WNA, 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):
+	Removed.
+
+	* deprecation.c (scm_include_deprecated_features): Simplified.
+
+	* eval.c (EVALCAR, unmemocopy), eval.h (SCM_XEVALCAR): Use
+	`SCM_IMP' instead of `!SCM_CELLP´.
+
+	* eval.c (unmemocopy): Eliminate redundant SCM_CELLP tests.
+	Extract side-effecting operations from macros.
+
+	(scm_init_eval): Don't initialize *top-level-lookup-closure*,
+	scm_top_level_lookup_closure_var and scm_system_transformer.
+
+	* gc.c (CELL_P): New local definition to replace SCM_CELLP.
+
+	(heap_segment):  Use CELL_P instead of SCM_CELLP.
+
+	* init.c (start_stack): Don't initialize
+	scm_top_level_lookup_closure_var and scm_system_transformer.
+
+	* modules.c (scm_set_current_module): Don't access

+2001-06-30  Dirk Herrmann  <D.Herrmann@tu-bs.de>

+

+
+	(scm_make_weak_vector, scm_make_weak_key_hash_table,

+	hash characters is possible (this was needed for implementing
+	SRFI-4's read synax `f32(...)').
+
+	* num2integral.i.c: Use scm_t_signed_bits instead of scm_t_bits,
+	because the latter is unsigned now and breaks comparisons like
+	(n < (scm_t_signed_bits)MIN_VALUE).
+

+

+
+	* eval.c (scm_evaluator_trap_table), eval.h (SCM_ENTER_FRAME_HDLR,

+2001-04-01  Dirk Herrmann  <D.Herrmann@tu-bs.de>
+
+	* gc.c (MARK):  Re-introduce a cheap sanity test for non debug
+	mode, as suggested by Michael Livshin.
+
+2001-03-31  Michael Livshin  <mlivshin@bigfoot.com>
+
+	* backtrace.c (display_backtrace_body): since the `print_state'
+	variable is not used (instead its data field is used directly as
+	`pstate'), protect it from the hungry compiler optimizations.
+	thanks to Bill Schottstaedt for the report.
+
+2001-03-30  Dirk Herrmann  <D.Herrmann@tu-bs.de>
+
+	* gc.[ch] (scm_tc16_allocated):  New type tag for allocated cells.
+	It is only defined and used if guile is compiled with
+	SCM_DEBUG_CELL_ACCESSES set to true.  It's purpose is, to never
+	let cells with a free_cell type tag be visible outside of the
+	garbage collector when in debug mode.
+
+	* gc.c (scm_debug_cell_accesses_p):  Set to true as default.
+
+	(scm_assert_cell_valid):  Use a local static variable to avoid
+	recursion.
+
+	(MARK):  Only check for rogue cell pointers in debug mode.  Use
+	scm_cellp for this purpose and place all checks for rogue pointers
+	into that function.  Further, since due to conservative scanning
+	we may encounter free cells during marking, don't use the standard
+	cell type accessor macro to determine the cell type.
+
+	(scm_cellp):  Check if the cell pointer actually points into a
+	card header.
+
+	(scm_init_gc):  Initalize scm_tc16_allocated.
+
+	* gc.h (GCH):  Renamed to SCM_GC_H.
+
+	(SCM_VALIDATE_CELL):  Enclose the expression in brackets.  This
+	might be unnecessary, but I feel better this way :-)
+
+	(SCM_GC_CELL_TYPE):  New macro.
+
+	(SCM_SETAND_CDR, SCM_SETOR_CDR):  Deprecated.  These are not used
+	in guile, and it is unlikely that they will be applied to real
+	pairs anyway.
+
+	(SCM_SET_FREE_CELL_TYPE):  Removed.  It was not used.
+
+	(SCM_GC_SET_ALLOCATED):  New macro.  Only non-empty if guile is
+	compiled with SCM_DEBUG_CELL_ACCESSES set to true.
+
+	(SCM_NEWCELL, SCM_NEWCELL2):  Use of SCM_GC_SET_ALLOCATED will
+	make sure that in debug mode no free cell will ever be visible
+	outside of the garbage collector.
+
+2001-03-30  Dirk Herrmann  <D.Herrmann@tu-bs.de>

+	Remove suspicious use of SCM_SLOPPY_CONSP.
+
+	* eq.c (scm_equal_p), tags.h (SCM_ECONSP):  Use SCM_CONSP instead

+
+	* eval.c (scm_m_define, scm_macroexp, SCM_CEVAL), print.c
+	(scm_iprin1):  Use new macro predicate and accessors.
+
+	* eval.h (scm_tc16_macro):  Removed declaration.  It is declared
+	in macros.h.
+
+	* eval.h (EVALH), macros.h (MACROSH), ports.h (PORTSH), procs.h
+	(PROCSH), tags.h (TAGSH), variable.h (VARIABLEH):  Renamed to
+	SCM_EVAL_H, SCM_MACROS_H, SCM_PORTS_H, SCM_PROCS_H, SCM_TAGS_H and
+	SCM_VARIABLE_H.  Even the macros that are used to inhibit
+	including a header file twice should be in the SCM_ namespace.
+
+	* fluids.c (scm_swap_fluids, scm_swap_fluids_reverse),
+	properties.c (scm_primitive_property_ref,
+	scm_primitive_property_del_x):  Prefer stronger predicates like
+	SCM_NULLP or SCM_FALSEP over SCM_IMP.
+
+	* gc.c (MARK):  Use proper macros to access procedure-with-setter
+	cell elements and closure cell elements.
+
+	(gc_sweep_freelist_finish, scm_gc_sweep, init_heap_seg):  Don't
+	access free cells as pairs.
+
+	(scm_unprotect_object):  scm_hashq_get_handle returns #f if
+	no hashtab entry is found.
+
+	* gc.c (scm_gc_sweep), ports.c (scm_close_port):  Use new macro
+	SCM_CLR_PORT_OPEN_FLAG.
+
+	* guardians.c (TCONC_IN), print.c (scm_free_print_state):  Don't
+	use SCM_SET_C[AD]R for uninitialized cells.
+
+	* hashtab.c (scm_hash_fn_get_handle):  Use SCM_VALIDATE_VECTOR.
+	If the hashtable has no slots, return #f instead of '().  This
+	unifies the return value with most assoc-functions.
+
+	(scm_hash_fn_ref):  Use proper type check.
+
+	(scm_hashq_get_handle, scm_hashv_get_handle, scm_hash_get_handle):
+	Removed references to non-existing functions from documentation.
+
+	* keywords.c (scm_keyword_dash_symbol):  Use proper macros to

+
+2001-03-08  Mikael Djurfeldt  <mdj@linnaeus.mit.edu>
+
+	* ramap.c (racp): Removed optimization which caused array copying
+	to fail if the two arrays shared storage.  Re-inserted the IVDEP
+	macros removed in the change of 2000-03-09.  (Don't really have a

+
+2001-03-05  Mikael Djurfeldt  <mdj@linnaeus.mit.edu>
+
+	* eval.c (scm_m_letstar): Removed check for duplicate bindings.

+	taking an unexpectedly large filename for an AF_UNIX socket from
+	bind/connect/sendto (thanks to Martin Grabmueller).

+	(scm_socket, scm_socketpair): cosmetic changes.
+	(scm_getsockopt, scm_setsockopt): declare optlen as int, not
+	size_t as socklen_t substitute.  don't restrict args/return values

+	avoid leakage.  use malloc, not scm_must_malloc.
+	(scm_connect, scm_bind, scm_sendto): use int, not size_t as socklen_t
+	substitute.  free the sockaddr structure before throwing an error.
+	(scm_init_add_buffer): procedure removed, together with its static
+	buffer scm_addr_buffer, which wouldn't be thread safe.  instead,
+	define a macro MAX_ADDR_SIZE and declare the buffer where needed.
+	(scm_accept, scm_getpeername, scm_getsockname, scm_recvfrom,
+	scm_sendto): use a local buffer instead of scm_addr_buffer.
+	adjust for new SCM_SOCK_FD_TO_PORT.  use int for address size,
+	not size_t.
+	(scm_recvfrom): set addr->sa_family to AF_UNSPEC before the recvfrom
+	call to detect whether recvfrom could be bothered to set the address.
+	(scm_init_socket): don't call scm_init_addr_buffer.

+	in the non-toplevel loop.
+	(nontoplevel_cdrxnoap, nontoplevel_cdrxbegin, nontoplevel_begin):

+	changes.
+	* ioext.c (scm_read_string_x_partial): don't crash if -1 is supplied
+	for fdes.  if current input port is used, check that it's a file
+	port.

+ 	SET_GREEDY, LISTED_P, SET_LISTED, CLR_LISTED, DESTROYED_P,
+ 	SET_DESTROYED): new defines/macros.
+	(GUARDIAN_LIVE, GUARDIAN_ZOMBIES, GUARDIAN_NEXT): deleted.
+	(add_to_live_list): takes a `guardian_t *' now, not SCM.
+	(guardian_print): print more info.
+	(guardian_apply): check if the guardian is destroyed, and throw an
+ 	error if so.  take one more optional argument `throw_p'.
+	(scm_guard): depending on the value of `throw_p', return a boolean
+ 	result.
+	(scm_get_one_zombie): remove redundant property test.
+	(guardian_t): represent the various (currently 3, I hope nothing
+ 	more gets added) boolean fields as bit flags.
+	(scm_guardian_destroyed_p, scm_guardian_greedy_p): new predicates.
+	(scm_destroy_guardian_x): new procedure.
+
+	* guardians.h: added prototypes for `scm_guardian_greedy_p' and

+
+	* fports.c (fport_write): bugfix: handle short writes for
