2003-02-28  Akim Demaille  <[e-mail]>

	* doc/autoconf.texi (Present But Cannot Be Compiled): New.

2003-02-28  Alexandre Duret-Lutz  <[e-mail]>

	* doc/autoconf.texi (Limitations of Make): Remove the section
	about `$<' in inference rules, it was a bogus interpretation of
	an old Automake change.  Discuss NetBSD, FreeBSD, OpenBSD, and
	Tru64 make in the "target lookup" section.
	(Automake): Automake 1.5+ no longer requires special tools to be
	present on the developer's host.

2003-02-26  Richard Dawe  <[e-mail]>

	${ac_make}.

	* lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS, _AC_OUTPUT_FILES):
	When constructing paths with IFS=:, quote the path. If we're
	constructing a DOS-style absolute path, we don't want to split it
	on the colon.

	* tests/atspecific.m4 (AT_CHECK_CONFIGURE): Fix typo
	in description.

2003-02-25  Pavel Roskin  <[e-mail]>

	* doc/autoconf.texi (Shell Substitutions): test -n -> test -z,
	to fix a mismatch between example and discussion.

2003-02-24  Kevin Ryde  <[e-mail]>

	* doc/autoconf.texi (Limitations of Builtins): Add notes on printf
	format starting with "-".

2003-02-20  Alexandre Duret-Lutz  <[e-mail]>

	* doc/autoconf.texi (Limitations of Make): `foo=bar make -e'
	is not portable inside Makefile.

2003-02-20  Akim Demaille  <[e-mail]>

	* lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): When
	compiler says yeah, but preproc says nope, compiler is right.
	Conversely, prompt the reader to send a bug report to the
	maintainers of the package, not of Autoconf.

2003-02-20  Klee Dienes  <[e-mail]>

	* bin/autoreconf.in (autoreconf_current_directory): Properly
	handle an empty aclocal.m4.

2003-02-20  Akim Demaille  <[e-mail]>

	* lib/autoconf/general.m4 (AC_PREFIX_PROGRAM): Quote

2002-12-23  Paul Eggert  <[e-mail]>

	* lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Define $1 to an
	innocuous variant befor including <limits.h> or <assert.h>.  This
	works around a bug reported by Albert Chin: HP-UX 11i
	(and earlier versions) have a <limits.h> that declares
	gettimeofday and many other functions.

2002-12-03  Paul Eggert  <[e-mail]>

	Version 2.57.

	* NEWS, configure.ac: Update version.

	* doc/fdl.texi: Upgrade to FDL version 1.2.

	* lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Use the function f
	nontrivially in main's body, so that f's external declaration is
	not optimized away in AIX.  This should fix the bug reported by
	Martin Frydl in
	<http://mail.gnu.org/pipermail/autoconf/2002-November/014508.html>.

	* lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C),
	_AC_PROG_PREPROC_WORKS_IFELSE): Use <limits.h> if __STDC__ is
	defined, to support freestanding compilers.  This should fix the
	bug reported by Momchil Velkov in
	<http://mail.gnu.org/pipermail/autoconf/2002-November/014490.html>.

	* doc/autoconf.texi (Obsolete Macros): Fix typos (insert empty
	arg, AC_DEFINE -> AC_DEFINE_UNQUOTED) in documentation for
	obsolete AC_CHECK_TYPE.  The missing empty arg was reported
	by Simon Josefsson in
	<http://mail.gnu.org/pipermail/autoconf-patches/2002-December/008830.html>.

	* Makefile.maint (www-gnu): New macro.
	(standards.texi-url_prefix, make-stds.texi-url_prefix): Use it, as
	the location has moved.

2002-12-02  Martin Frydl  <[e-mail]>

	* bin/autom4te.in (at_flatten): rewritten to avoid M4 problem when
	\(.*\) match is too long and there is something more to be checked.
	<http://mail.gnu.org/pipermail/autoconf/2002-November/014524.html>

2002-11-15  Akim Demaille  <[e-mail]>

	* config/config.guess, config/config.sub, config/install-sh:
	Update from masters.

2002-11-14  Akim Demaille  <[e-mail]>

	* Makefile.maint: Sync with Bison, i.e.:
	(po-check): Scan .l and .y files instead of the
	.c and the .h files that they generate.  This fixes the bug
	reported by Tim Van Holder in:
	<http://mail.gnu.org/pipermail/bison-patches/2002-November/001352.html>
	Look for N_ as well as for _.  Try to avoid matching #define for
	N_ and _.
	From Paul Eggert.

2002-11-14  Akim Demaille  <[e-mail]>

	* doc/autoconf.texi (C Compiler): Compiling several files at once.
	From Paul Eggert and Albert Chin-A-Young.

2002-11-14  Akim Demaille  <[e-mail]>

	* doc/autoconf.texi (C Compiler): Solitary backslashes.
	From Paul Eggert and Albert Chin-A-Young.

2002-11-14  Kevin Ryde  <[e-mail]>

	* lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Initialize f=$1 rather
	than assigning in main, to avoid HP cc +O3 optimizing it away.

2002-11-12  Peter Eisentraut  <[e-mail]>

	* lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Add -q
	option.  Process --recheck after parsing all options.  Pass -q
	option to configure on --recheck.
	(AC_OUTPUT): Pass -q from configure to config.status.
	* lib/autoconf/general.m4 (_AC_INIT_PREPARE): Strip -q from
	arguments to record.
	* doc/autoconf.texi (config.status Invocation): Document
	config.status -q option.

2002-11-07  Alexandre Duret-Lutz  <[e-mail]>

	* bin/autoscan.in (scan_file): Scan Makefile.am too. Ignore
	Makefile.in if Makefile.am exists.
	(output): Strip `.am' from Makefiles.  Don't
	output AC_CONFIG_FILES if no Makefiles were found.

2002-11-07  Akim Demaille  <[e-mail]>

	* Makefile.am (cvs_files): Add elisp-comp, mdate-sh.
	(local_updates): New.
	* Makefile.maint: Update, from CVS Bison.
	(local_updates): New.

2002-11-06  Akim Demaille  <[e-mail]>

	* tests/torture.at (Configuring subdirectories): Don't use grep
	-w.
	* doc/autoconf.texi (Limitations of Usual Tools): Grep -w.
	Reported by Ezra Peisach.

2002-11-05  Akim Demaille  <[e-mail]>

	* lib/autoconf/autoheader.m4 (_AH_TEMPLATE_OLD, _AH_VERBATIM_OLD):
	Remove.
	We _have_ to stop using the old compatibility scheme that tried to
	avoid useless backslashes because Libtool 1.4.3 contains a
	AC_DEFINE([error_t], [int],
	[Define to a type to use for \`error_t' if it is not
	otherwise available.])
	We _have_ to quote the single quote and backslashes with \.  The
	old compatibility scheme saw that ` was backslashed, and therefore
	did not quote the single quote.  Hence before this patch, Autoconf
	was not compatible with Libtool.

2002-11-04  Paul Eggert  <[e-mail]>

	* lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Set the following variables,
	too: LC_ADDRESS, LC_IDENTIFICATION, LC_MEASUREMENT, LC_MONETARY,
	LC_NAME, LC_PAPER, LC_TELEPHONE.
	* doc/autoconf.texi (Special Shell Variables): Mention those vars.

2002-11-04  Akim Demaille  <[e-mail]>

	* bin/autoreconf.in (&autoreconf_current_directory): New, extracted
	from...
	(&autoreconf): here.
	($help, $make, &parse_args, &autoreconf_current_directory):
	Support -m/--make.
	* doc/autoconf.texi (autoreconf Invocation): Adjust.

2002-10-31  Bruno Haible  <[e-mail]>

	* lib/autoconf/functions.m4 (_AC_FUNC_MALLOC_IF): Change message.
	Change name of cache variable to ac_cv_func_malloc_0_nonnull.
	(AC_FUNC_MALLOC): Change description of HAVE_MALLOC macro.

2002-10-31  Akim Demaille  <[e-mail]>

	* lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Use and display
	`$(MAKE)' instead of '${MAKE}' to emphasize that we refer to the
	Make variable, not a shell variable.
	Suggested by Bruno Haible.

	(_AC_RUN_IFELSE): Use it.
	* lib/autoconf/lang.m4 (_AC_COMPILER_OBJEXT):
	(_AC_COMPILER_EXEEXT_DEFAULT): Likewise.
	* lib/autoconf/c.m4 (AC_LANG_SOURCE): Don't include confdefs.h,
	inline it.

2002-10-30  Akim Demaille  <[e-mail]>

	* bin/autom4te.in (&parse_args, $help): Support --no-cache.
	* doc/autoconf.texi (autom4te Invocation): Adjust.

2002-10-29  Akim Demaille  <[e-mail]>

	* tests/torture.at (Deep Package): New test.
	(Configuring subdirectories): Don't use a testSubDir as Autotest
