2000-01-09  Gary Houston  <ghouston@arglist.com>

	* These changes should make it unnecessary to call tzset from
	Scheme after modifying the TZ environment variable, even if the
	system date facilities cache the value.
	* stime.c (setzone, scm_localtime): added comments.
	(tzset): don't define a noop tzset macro if HAVE_TZSET not defined.
	(setzone): don't call tzset.
	(restorezone): call tzset only if HAVE_TZSET is defined.
	(scm_tzset): don't define if HAVE_TZSET not defined.  Change the
	doc string to indicate that this procedure isn't likely to do
	anything useful.
	(scm_localtime, scm_strftime, scm_mktime): call tzset if
	LOCALTIME_CACHE is defined.

2000-01-09  Mikael Djurfeldt  <mdj@thalamus.nada.kth.se>

	* posix.c (scm_sync): Return SCM_UNSPECIFIED.

2000-01-09  Gary Houston  <ghouston@arglist.com>

	* eval.c: define scm_unbound_variable_key ('unbound-variable).
	scm_lookupcar1: throw an error with key 'unbound-variable instead
	of 'misc-error when an unbound variable is encountered.

	* filesys.c (scm_mkdir, scm_rmdir, scm_getcwd, scm_select, 
	scm_symlink, scm_readlink, scm_lstat),
	posix.c (scm_setpgid, scm_setsid, scm_ctermid, scm_tcgetpgrp,
	scm_tcsetpgrp, scm_uname, scm_setlocale, scm_mknod, scm_nice,
	scm_sync),
	simpos.c (scm_system), 
	stime.c (scm_times, scm_strptime):
	move the HAVE_XXX feature tests out of the procedure bodies.
	don't use SCM_SYSMISSING.
	scm_validate.h (SCM_SYSMISSING): removed.
	error.h, error.c (scm_sysmissing): comment that this is deprecated.
	see ChangeLog entry for 1999-12-28.

Sat Jan  8 19:52:04 2000  Greg J. Badros  <gjb@cs.washington.edu>

	* scm_validate.h (SCM_VALIDATE_BOOL_COPY): Fix typo.

Sat Jan  8 17:06:46 2000  Greg J. Badros  <gjb@cs.washington.edu>

	* backtrace.c: Fix spelling typo in a comment.

	* snarf.h: Use new SCM_DOCS macro to encapsulate the non SCM_INIT
 	text.  Reformatted some of the expansions.

Fri Jan  7 15:50:46 2000  Greg J. Badros  <gjb@cs.washington.edu>

	* scm_validate.h (SCM_OUT_OF_RANGE): Use scm_out_of_range_pos to
	report the position of the argument.

	* error.h, error.c (scm_out_of_range_pos):  Added this function to 
	take extra "pos" argument, the position number of the errant
	argument. 

	* debug.c: Use SCM_OUT_OF_RANGE instead of scm_out_of_range.

	* snarf.h: Use SCM_HERE and SCM_INIT as names, not SCM_NOTSNARF
	and SCM_SNARFING.  Also put the %%% in the SCM_INIT since Mikael
	prefers that and I'm reasonably indifferent.

Fri Jan  7 15:03:32 2000  Greg J. Badros  <gjb@cs.washington.edu>

	* snarf.h: Factor out differences between C++ and non-C++ into
	SCM_FUNC_CAST_ARBITRARY_ARGS macro.  Modify all the snarf macro
	definitions to use SCM_NOTSNARF and SCM_SNARFING macros (like
	Mikael's macros, below, but changed names and SCM_SNARFING no
	longer expands to include %%% -- that must appear in the argument
	so that the token appears at the call-site as a reminder).

2000-01-07  Mikael Djurfeldt  <mdj@thalamus.nada.kth.se>

	* snarf.h (SCM_INSITU, SCM_INIT): New snarf macros for use in user
	snarf macro definitions.

2000-01-06  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>

	* chars.c (scm_integer_to_char): Use Greg's nice
	SCM_VALIDATE_INUM_RANGE macro for argument checking for closer
	adherence to R5RS.

Thu Jan  6 11:48:49 2000  Greg J. Badros  <gjb@cs.washington.edu>

	* *.c, snarf.h: Replace GUILE_PROC1 with SCM_DEFINE1 throughout.

Thu Jan  6 11:22:53 2000  Greg J. Badros  <gjb@cs.washington.edu>

	* Makefile.am (ETAGS_ARGS): Switch to SCM_DEFINE, SCM_DEFINE1
	instead of GUILE_PROC.

Thu Jan  6 11:21:49 2000  Greg J. Badros  <gjb@cs.washington.edu>

	* alist.c: Do not report mismatch errors on some uses of `tmp' (do 
	this by using SCM_ARG2 instead of `2' in the SCM_VALIDATE_CONS
	macro call.

Thu Jan  6 09:54:33 2000  Dirk Herrmann <dirk@ida.ing.tu-bs.de> --gjb applied

	* scm_validate.h: Remove some redundant NIMP tests.

	* alist.c: minimize scope of the tmp variables, and initialize
 	them when declared. The strange SCM_NIMP tests are replaced by
 	SCM_CONSP tests that more closely reflect the intended semantics.
  	However, we don't get a performance penalty here, because the
 	SCM_CONSP test was performed by the ALISTCELL test anyway.  * The
 	extremely ugly use of ASRTGO macros was removed: The calls to
 	ASRTGO were not encapsulated by "#ifndef SCM_RECKLESS", but got a
 	label parameter that only exists when SCM_RECKLESS is not defined.
  	This works, because ASRTGO itself is defined in a way that it only
 	makes use of the label parameter if SCM_RECKLESS is not defined
 	(shudder!).  Does guile make at all use of the possibility to
 	define SCM_RECKLESS?  * Codesize is likely to be reduced, since
 	instead of two calls to SCM_ASSERT performed by the ALISTCELL test
 	we now only get one test.

	* list.c: Use SCM_NNULLP, not SCM_NIMP as appropriate.  Also use
 	SCM_NULLP instead of SCM_IMP.  Drop use of "register" keyword on
 	some variables in `list?'.  Fix `reverse' and `reverse!'
 	primitives to handle improper lists better.

Wed Jan  5 11:24:53 2000  Greg J. Badros  <gjb@cs.washington.edu>

	* *.[ch]: Whitespace changes -- added space after SCM_VALIDATE_*
 	macros and SCM_DEFINE macros to match GNU coding standards.

Wed Jan  5 11:04:24 2000  Greg J. Badros  <gjb@cs.washington.edu>

	* *.[ch]: Replace GUILE_PROC w/ SCM_DEFINE.

Wed Jan  5 10:59:06 2000  Greg J. Badros  <gjb@cs.washington.edu>

	* *.[ch]:  Replace SCM_VALIDATE_INT w/ SCM_VALIDATE_INUM for
	better consistency with the names of other SCM_VALIDATE_ macros
	and better conformance to guile naming policy.

Wed Jan  5 10:50:39 2000  Greg J. Badros  <gjb@cs.washington.edu>

	* ports.c (s_scm_close_all_ports_except): Use SCM_ARG1 in a
	SCM_VALIDATE instead of 1 to avoid a check on the argument (since
	it's not the actual name of the formal).

	* guile-snarf.awk.in: Do argument/number mismatch checking and
	print warnings in an Emacs compile-mode parseable format.

	* struct.c: Use SCM_ASSERT_RANGE instead of SCM_ASSERT w/
	SCM_OUTOFRANGE as 3rd argument.

	* random.c: Fix argument/number mismatch (that I introduced :-( ).

	* __scm.h: Do not #define SCM_ARG* when snarfing;
	lets us distinguish between 1 and SCM_ARG1 when snarfing as only
	the former (using the number) requires the argument to match the
	formal in the current argument snarfing check.

	* snarf.h: Give new definition of SCM_ASSERT when in
	snarfing mode to output a lexically-identifiable sequence that the 
	guile-snarf.awk script uses to verify argument/position matching.

	* ramap.c: Remove extraneous #undef FUNC_NAME.

Wed Jan  5 08:36:38 2000  Greg J. Badros  <gjb@cs.washington.edu>

	* guile-doc-snarf.awk.in: Removed -- guile-snarf.awk.in is the
	current version of the same functionality; it writes the .x output 
	to stdout instead of directly into the file.

Wed Jan  5 08:15:04 2000  Greg J. Badros  <gjb@cs.washington.edu>

	* unif.c, symbols.c, strings.c, stacks.c, random.c, print.c,
	posix.c:  Eliminated a bunch of SCM_NIMP(..)s that are now
	redundant with the safer macros.  Patch from Dirk Hermann applied
	by hand. Thanks Dirk!

	* scm_validate.h: Added SCM_VALIDATE_VECTOR_OR_DVECTOR for some
	uses in random.c.

	* ramap.c: whitespace change.

Tue Jan  4 14:21:35 2000  Greg J. Badros  <gjb@cs.washington.edu>

	* options.c, objects.c, keywords.c, gc.c: Some redundant SCM_NIMP
 	removals from Dirk Hermann.

	* alist.c: Rename formals to match the parameter names in the
	documentation, updates to documentation.  Thanks Dirk Hermann!

2000-01-04  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>

	* eval.c (SCM_CEVAL): Reverse order of
	scm_stack_checking_enabled_p and SCM_STACK_OVERFLOW_P
	(Thanks to Brad Knotwell.)

Mon Jan  3 08:30:02 2000  Greg Harvey  <Greg.Harvey@thezone.net> (applied --01/03/00 gjb)

	* gc.c (scm_debug_newcell): Added SCM_SETCAR of the newly
	allocated cell. 

	* pairs.h: Added a comment about the need for the SCM_SETCAR in
	SCM_NEWCELL macro.

Mon Jan  3 08:25:19 2000  Greg J. Badros  <gjb@cs.washington.edu>

	* dynl-vms.c, debug.c, coop-threads.c, backtrace.c, eval.c: More
 	SCM_NIMP tests that were redundant are now eliminated.  Patches
 	from Dirk Hermann applied by hand.
