2003-05-28  Paul Eggert  <[e-mail]>

	* NEWS, doc/autoconf.texi (Particular Functions),
	lib/autoconf/functions.m4 (AC_FUNC_MKTIME): Check that mktime
	is the inverse of localtime.

2003-05-25  Alexandre Duret-Lutz  <[e-mail]>

	Do not call `_exit()', simply modify `$?'.
	(xsystem): Reset $! before running system, and check it afterward.
	* tests/tools.at (autoupdating AC_PREREQ): Expect exit status
	63 for version mismatches.

2003-05-23  Akim Demaille  <[e-mail]>

	* lib/autoconf/status.m4: Prefer "TAB-SP" to "SP-TAB", because of
	Emacs' dangerous whitespace.el behavior (smashing "useless" spaces in
	the middle of a line).
	* lib/m4sugar/m4sugar.m4: Likewise.
	Remove useless spaces in comments.

2003-05-23  Akim Demaille  <[e-mail]>

	* lib/m4sugar/m4sugar.m4 (m4_version_prereq): Failure causes an
	exit 63, so that we (or Automake's "missing") can tell the
	difference with a plain failure.
	* doc/autoconf.texi (Notices): Adjust.

2003-05-23  Akim Demaille  <[e-mail]>

	* Makefile.am, bin/Makefile.am, config/Makefile.am,
	* doc/Makefile.am, lib/autoconf/Makefile.am, tests/Makefile.am:
	White spaces cleanup.

2003-05-22  Jim Meyering  <[e-mail]>
	    Paul Eggert <[e-mail]>

	* lib/autoconf/c.m4 (_AC_PROG_CXX_EXIT_DECLARATION):
	Remove `#include <stdlib.h>' from the list; we should never
	make confdefs.h include <stdlib.h> or <cstdlib>, because the
	resulting namespace pollution would cause other tests to fail.
	Configure scripts run with some older versions of g++ and HP's
	aCC would fail due to such an #include.  Problems reported by
	Matthew Mueller in <http://bugs.debian.org/120704> and by
	Keith Bostic in
	<http://mail.gnu.org/archive/html/autoconf/2003-05/msg00063.html>.
	In the test, use the test declaration before including <stdlib.h>,
	as that's closer to how it'll be used.

2003-05-23  Akim Demaille  <[e-mail]>

	* doc/autoconf.texi (Header Portability): ucred.h.
	From Ian Redfern.

2003-05-22  Paolo Bonzini  <[e-mail]>

	Overhaul Autotest's logging: generate separate log files
	in testsuite.dir/NNN/testsuite.log, and append them to
	testsuite.log instead of re-running the test verbosely.

	* lib/autotest/general.m4 (AT_INIT): Use a single redirected
	file descriptor, write 0 to at_status_file instead of setting
	at_status=0, initialize some new variables (at_status_file,
	at_group_log, at_suite_log, at_tee_pipe).  Remove the cruft
	to rerun the tests, instead append the at_group_log to the
	at_suite_log when a test fails.
	(AT_SETUP): pipe the test case's output into at_tee_pipe,
	with the AS_MESSAGE_LOG_FD redirected to stdout.
	(AT_CLEANUP): save the output status in $at_status_file
	and restore it, redirect the AS_MESSAGE_LOG_FD back to
	its original place.
	(AT_CHECK): since tests are run with a redirected stdout,
	and used to be re-run in verbose mode, turn some $at_verbose
	into echo, and don't redirect the output of testing stdout
	and stderr.

	* lib/autotest/autoconf.texi (testsuite Scripts): Update
	the name of the debugging directory and information about
	its contents.

2003-05-22  Paolo Bonzini  <[e-mail]>

	* lib/m4sugar/m4sh.m4 [AS_REQUIRE]: actually use the 2nd

	and truncate.

2003-05-06  Akim Demaille  <[e-mail]>

	Don't try to be smart with aclocal 1.8+ because (i) aclocal no
	longer updates aclocal.m4 if useless, (ii) if a file m4_included
	by aclocal.m4 is changed it might require the importing of another
	m4 extension file, i.e., aclocal must be run.

	* bin/autoreconf.in (&run_aclocal, $aclocal_supports_force): New.
	(&parse_args): Use --force with aclocal if required and supported.

	* bin/autom4te.in (&Request::save, &Request::load): Use an IO::File
	argument instead of a file name, so that the request file remains
	open during the whole autom4te run.
	($icache_file): New.
	(&freeze): Lock the $icache_file.

2003-04-29  Derek Price  <[e-mail]>

	* lib/autotest/general.m4 (AT_KEYWORDS): Don't use a comma as the
	seperator with m4_append_uniq().  It doesn't work.
	(AT_CLEANUP): Add `;' to end of at_help_all.
	(AT_INIT): Allow --keywords to be specified more than once.  When
	grepping $at_help_all for keywords, use the field and keyword
	seperators to ensure a complete keyword match.  Alter at_prev handling
	to support the new --keywords behavior.

2003-04-27  Karl Berry  <[e-mail]>

	* doc/autoconf.texi: Make the dir entries in the autoconf manual
	align better with others.  I also made some of the individual

	header causes problems.

2003-03-28  Akim Demaille  <[e-mail]>
