	Suggested by Guido Draheim.

2002-09-13  Akim Demaille  <akim@epita.fr>

	* bin/autoreconf.in: Don't use Cwd::chdir, since in its internals
	(chdir_init) might hang when stat'ing mounted directories.
	Reported by Vance Shipley.

2002-09-12  Akim Demaille  <akim@epita.fr>

	* bin/autoscan.in (&parse_args): Pass a reference to the lists, not

2002-09-12  Akim Demaille  <akim@epita.fr>

	* doc/autoconf.texi: Review grammar and punctuation.

	* doc/autoconf.texi: Fix minor formatting, spelling, and
	grammatical typos.
	(Defining Symbols): Explain that AC_DEFINE(var) defaults to 1, but
	AC_DEFINE(var,,description) does not; and the AC_DEFINE(var) case
	is obsolescent.

2002-09-11  Akim Demaille  <akim@epita.fr>

	* doc/autoconf.texi (Questions): Rename as...
	(FAQ): this.
	(Defining Directories): New.

2002-09-09  Akim Demaille  <akim@epita.fr>

	plain `@' is wanted.

2002-09-09  Akim Demaille  <akim@epita.fr>

	* lib/autoconf/general.m4 (_AC_INIT_PREPARE): Keep the
	`duplicates', since the algorithm was too naive and could keep
	`--prefix=1 --prefix=2 --prefix=1' as `--prefix=1 --prefix=2', and
	keep `--prefix foo --prefix bar' as `--prefix foo bar'.
	Reported by Ralf Corsepius.

2002-09-05  Akim Demaille  <akim@epita.fr>

	* bin/Makefile.am (autoconf, autoheader, autoreconf, autoupdate)
	(ifnames, autoscan, autom4te): Since we don't only depend on
	configure.ac variables (such as VERSION etc.), but also on prefix
	and so forth, depend on Makefile, not configure.ac.
	Reported by Alexandre Duret-Lutz.
	* doc/autoconf.texi (Installation Directory Variables): Adjust.

2002-09-05  Kevin Ryde  <user42@zip.com.au>

	* autoconf.texi (Limitations of Make): HP-UX trailing backslashes
	doesn't seem to be confined to ia64, just say "some versions".

	* Makefile.am, doc/Makefile.am: Remove pdf targets, handled by
	Automake 1.6c.

2002-09-02  Jim Meyering  <meyering@lucent.com>

	* doc/autoconf.texi (AC_SYS_POSIX_TERMIOS): Reflect renaming: s/am/ac/,
	i.e., change am_cv_sys_posix_termios to ac_cv_sys_posix_termios.
	Also, tweak grammar: s/make sure to/be sure to/.

2002-09-02  Paul Eggert  <eggert@twinsun.com>

	* doc/autoconf.texi (Limitations of Builtins): Explain why logical
	directory names are generally preferable to physical names.

2002-09-02  Akim Demaille  <akim@epita.fr>

	* lib/Autom4te/General.pm (&update_file): s/die/error/.
	Reported by Raja R. Harinath.
	* bin/autoheader.in, bin/autoreconf.in, bin/autoscan.in,
	* bin/autoupdate.in: Use error instead of die.

2002-09-01  Paul Eggert  <eggert@twinsun.com>

	* tests/mktests.sh (ac_exclude_egrep, au_exclude_egrep): Use
	ordinary shell concatenation rather than echo+tr+sed command that
	runs afoul of a long-line-related sed bug in Solaris 8.

	* bin/autoheader.in (parse_args): --warning -> --warnings.

	* bin/autoconf.as: Work even if "ls" outputs "FOO not found" to
	stdout, as traditional "ls" does.
	* lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT,
	_AC_COMPILER_EXEEXT_O): Likewise.
	* doc/autoconf.texi (Limitations of Usual Tools): Add "ls".

	* bin/autoconf.as: Add --prepend-include option.  This patch was
	applied to bin/autoconf.in in the 2002-07-17 patch by Mark D. Roth,
	but bin/autoconf.in is generated automatically from bin/autoconf.as.

	* bin/autoconf.in, configure: Regenerate.

	* doc/autoconf.texi (Special Shell Variables): Mention
	ENV, MAIL, MAILPATH, PS1, PS2, PS4.  Index PWD.

	* lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Unset ENV, MAIL,
	MAILPATH and set PS1, PS2, PS4 to default values, to work
	around bug in pre-3.0 UWIN ksh reported by Bruce Lilly.
	For LC_ALL etc, first try to set to "C" as POSIX requires and as
	the Autoconf documentation specifies; fall back to "unset" only if
	this fails.  Use a shell for-loop for this rather than an m4 loop,
	to shorten the output script.

2002-08-30  Paul Eggert  <eggert@twinsun.com>

	* doc/autoconf.texi (Special Shell Variables): Mention POSIX
	1003.1-2001's requirements for CDPATH.  Give a simpler workaround
	for the CDPATH problem.  Document PWD.
	(Limitations of Builtins): Document the problem that "cd $foo" and
	"ls $foo" may refer to different directories in shells conforming
	to POSIX 1003.1-2001.  Use PS1 rather than CDPATH for "unset"
	example, since the old example is now out of date.

	* lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Reject FOO if "cd
	FOO" and "ls FOO" talk about different directories; this catches
	problems when POSIX 1003.1-2001 "cd" fails due to symlink
	spaghetti.

	* lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Use AS_UNSET instead
	of rolling our own unset.
	(_AS_PREPARE): $as_unset CDPATH instead of AS_UNSETting it, since
	in practice we needn't worry about CDPATH if unset doesn't work.

	* Makefile.in, aclocal.m4, bin/Makefile.in,
	config/Makefile.in, doc/Makefile.in, lib/Makefile.in,
	lib/Autom4te/Makefile.in, lib/autoconf/Makefile.in,

	lib/emacs/Makefile.in, lib/m4sugar/Makefile.in, man/Makefile.in,
	tests/Makefile.in: Regenerate with Automake 1.6.3.

	* config/config.guess, config/config.sub, config/mkinstalldirs:
	Update.

	* configure: Regenerate with self.

	default output.

2002-08-29  Rainer Orth  <ro@TechFak.Uni-Bielefeld.DE>

	failure.

2002-08-29  Akim Demaille  <akim@epita.fr>

	* lib/Autom4te/General.pm (&xqx): New.
	(&xsystem): Use WIFEXITED and WEXITSTATUS instead of decoding $? by
	hand, which is not portable.
	(&error): New.
	* bin/autom4te.in: Use them.
	Use &error instead of die.
	* tests/m4sugar.at (m4_warn, m4_require: circular dependencies):
	Adjust.

2002-08-17  Paul Eggert  <eggert@twinsun.com>

	* lib/autoconf/fortran.m4 (AC_PROG_F77): Remove fc from the
	default list of compilers to try, since it was long ago superseded
	by the ksh fc builtin.  Suggested by Steven G. Johnson.

2002-07-31  Alexandre Duret-Lutz  <duret_g@epita.fr>

	* doc/autoconf.texi (Invoking autom4te): End the option table,
	fixing a bug introduced by the previous patch.
	(Limitations of Make): Add a 'target lookup' subentry in the
	'VPATH' entry.  Rewrite all `make' occurences as `@command{make}'.

2002-07-29  Mark D. Roth  <roth@feep.net>

	* bin/autom4te.in: Remove --include-envvar and --site-macro-subdir
	options and use $AUTOM4TE_PATH.
	* doc/autoconf.texi: Remove documentation of autom4te
	--include-envvar and --site-macro-subdir options and document
	use of $AUTOM4TE_PATH.
	* lib/autom4te.in: Remove --include-envvar and --site-macro-subdir
	arguments from each language section.

2002-07-29  Paul Eggert  <eggert@twinsun.com>

	* doc/install.texi: Include copyright symbol in copyright notice.

	* Makefile.am (MAKEINFO): Remove; it's a user-specified macro.
	Replace with:
	(AM_MAKEINFOFLAGS): New macro.
	* doc/Makefile.am (MAKEINFO, AM_MAKEINFOFLAGS): Likewise.
	* Makefile.am (INSTALL): Use the new macros.
	Use -o rather than --output, since "missing" does not grok --output.

2002-07-25  Alexandre Duret-Lutz  <duret_g@epita.fr>

	* doc/autoconf.texi (Limitations of Make): Escaped newlines in
	comments do not always work. Never trust the exit status of
	`make -k'.

2002-07-24  Kevin Ryde  <user42@zip.com.au>

	* autoconf.texi (Limitations of Make, Making testsuite Scripts):
	Untabify, since tabs are not enjoyed by texi2dvi and makeinfo.

2002-07-23  Paul Eggert  <eggert@twinsun.com>

	* lib/m4sugar/m4sh.m4 (_AS_PATH_SEPARATOR_PREPARE):
	Use PATH="/nonexistent;.", not PATH=".;.", as FreeBSD ksh2002
	apparently treats PATH="nonexistent" as if it contained ".".
	Bug reported by Stefan `Sec' Zehl.

2002-07-22  Alexandre Duret-Lutz  <duret_g@epita.fr>

	* doc/autoconf.texi (Limitations of Make): Mention the special

	Both macros now accept an optional source-dir arg.
	New macro AC_GNU_SOURCE to define _GNU_SOURCE.

	* NEWS: Document this.
	* doc/autoconf.texi (Particular Functions, UNIX Variants): Likewise.

	* lib/autoconf/functions.m4 (_AC_FUNC_FNMATCH): New macro.
	(AC_FUNC_FNMATCH): Use it.  Test only for POSIX conformance,
	not for GNU extensions; this undoes part of the 2000-11-03 change,
	reverting to 2.13-compatible behavior.
	Add new optional argument DIR.
	(AC_FUNC_FNMATCH_GNU): New macro.

	* lib/autoconf/specific.m4 (AC_GNU_SOURCE): New macro.

2002-05-08  Paul Eggert  <eggert@twinsun.com>

	* lib/autoconf/headers.m4 (AC_HEADER_TIOCGWINSZ):
	Don't require AC_SYS_POSIX_TERMIOS.  The test is unnecessary,
	and it causes a 'test' syntax error if it fails.
	Bug reported by Stephen Gildea.

	* lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
	If prototypes are supported, use them to check this at compile-time,
	instead of trying to check it at run-time.  If we must do a run-time
	check, assume that setvbuf is standard when cross-compiling, as
	nonstandard setvbuf occurs only on ancient and unlikely hosts.
	Bug reported by Paul D. Smith.

	* lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Add optional
	argument specifying location of getloadavg.c.  This removes a
	FIXME.  This idea was taken from Jim Meyering's implementation in
	textutils.
	* doc/autoconf.texi (Particular Functions): Document this.
	Also, mention HAVE_NLIST_H rather than NLIST_STRUCT, since
	that's what the code does; this fixes a bug reported by
	Paul D. Smith.

2002-05-03  Akim Demaille  <akim@epita.fr>

	* bin/autoreconf.in (autoreconf): Rewrite to use Gettext's

	* bin/autoreconf.in (autoreconf): Don't age aclocal.m4's input
	files to be 1 second older; just set them to be the same time.
	Also, sleep 1 second after the first aclocal, to work around
	problems with sub-second time stamps on the input files.

	From Christian Cornelssen.

2002-04-29  Akim Demaille  <akim@epita.fr>

	* tests/m4sh.at (LINENO): If testsuite itself is rewritten because
	of lack of $LINENO support, then the test will compare the $LINENO
	in testsuite vs. the lineno in the test file.  This is wrong, of
	course.
	Be sure to protect it.
	Reported by Patrick Welche.

2002-04-25  Akim Demaille  <akim@epita.fr>

	* bin/autoreconf.in (autoreconf): Don't let aclocal.m4 be older
	than some of the input files, hence, on the second run of aclocal,
	if some of its input are younger, make them older.
	Suggested by Paul Eggert.

2002-04-25  Akim Demaille  <akim@epita.fr>

	DEFAULT diversion.
	(_AC_INIT_PREPARE): Use them to log them.
	(_AC_SUBST, _AC_SUBST_SED_PROGRAM): Remove.
	(AC_SUBST, AC_SUBST_FILE): Instead of buliding the
	_AC_SUBST_SED_PROGRAM, store the list of output files/variables in
	_AC_SUBST_FILES and _AC_SUBST_VARS.
	* lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Adjust.

2002-04-24  Akim Demaille  <akim@epita.fr>

	* tests/m4sh.at (AT_DATA_LINENO): Use _AS_PREPARE.

	Adjust Autoconf and Autotest.

	* lib/m4sugar/m4sh.m4 (_AS_MKDIR_P_PREPARE): New macro.
	(AS_MKDIR_P): Require it.  Use mkdir -p if available, falling
	back on AS_DIRNAME to compute prefixes otherwise; this is
	roughly what mkinstalldirs does.  That way, we need not have
	our own filename disassembler.  The old disassembler did not
	work with Solaris 8 dtksh, which is ksh Version M-12/28/93d.

	* lib/autotest/general.m4 (AT_INIT, AT_CLEANUP):
	Create at_test_all by a series of assignments,
	not by a single assignment of a long string.  The latter causes ksh
	version 11/16/88g to silently misbehave on OpenServer 5.0.6a,
	presumably because of a buffer overrun.

	variable when looking for the prefix program.
	Now it also works for shell variables.

2002-02-07  Akim Demaille  <akim@epita.fr>

	* doc/autoconf.texi (Limitations of Builtins): More about
	case/esac.

2002-02-06  Akim Demaille  <akim@epita.fr>

	not unsigned long.
	* tests/semantics.at (AC_CHECK_SIZEOF): Check non-GCC
	cross-compilers, too.  This undoes some of the most recent change
	to this file.

2002-02-05  Akim Demaille  <akim@epita.fr>

	* tests/Makefile.am (check_SCRIPTS): Use it, instead of WRAPPERS,
	to make sure they are up to date when `check' is run.

2002-02-05  Akim Demaille  <akim@epita.fr>

	* doc/autoconf.texi (Making testsuite Scripts): Document
	package.m4.

	* lib/m4sugar/m4sh.m4: Don't include files given by autom4te.

2002-02-05  Akim Demaille  <akim@epita.fr>

	* bin/autom4te.in (&parse_args): Implement `frozen files are
	optional are the sum of the previous files on the command line'.
	Also, pass `--reload-state=' on them, so...
	(handle_m4): don't.
	* lib/autom4te.in (Autotest, Autoconf): Rely on M4sh.
	(M4sh): Rely on M4sugar.
	(Autotest, M4sh, M4sugar): Use frozen files.

2002-01-31  Akim Demaille  <akim@epita.fr>

	* lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Accept $4.
	* doc/autoconf.texi (Initializing configure): Adjust.

2002-01-30  Akim Demaille  <akim@epita.fr>

	alphanumeric to `-' instead of `_'.

2002-01-30  Akim Demaille  <akim@epita.fr>

	* tests/semantics.at (AC_CHECK_SIZEOF): Split into two tests: one
	for plain code, the other for cross-compilation code.  The latter

	so that aclocal 1.4 works.
	Reported by Alexandre Duret-Lutz and Larry Schmitt.

2002-01-28  Akim Demaille  <akim@epita.fr>

	* doc/autoconf.texi (Writing testsuite.at): AT_CLEANUP no longer
	needs an argument.

2002-01-28  Akim Demaille  <akim@epita.fr>

	* lib/autotest/general.m4 (AT_INIT): Don't be ridiculous: adjust
	AUTOTEST_PATH *after* it was set.
	Don't put `.' in the PATH: the user should be precise and `./' if
	needed.  In addition, given that the test suite does some `cd', if
	`.' is in the path, the `tested programs' sections will report
	programs found in the test suite's directory, while during the
	tests (performed in their own directory), these programs are no
	longer visible.  In other words, the results is confusing and
	useless.
	* tests/m4sh.at: Adjust: don't rely on `.' being in the PATH.

2002-01-24  Akim Demaille  <akim@epita.fr>

	(_AS_PATH_SEPARATOR_PREPARE): Don't expect $SHELL to be
	Bourne. Use /bin/sh.
	From Andreas Buening.

2002-01-06  Akim Demaille  <akim@epita.fr>

	Suggested by Jonathan Kamens.

2001-12-14  Aaron M. Ucko  <amu@alum.mit.edu>

	Remove $filepath, useless.
	(&scan_makefile): Don't remove the $(FOO), ${FOO} and @FOO@
	variables, they are really part of the tokens.
	Split the input line on spaces and then look for tokens.

	* doc/autoconf.texi (Using an Autotest Test Suite): New.
	(testsuite Scripts): Be one of its subsection.
	(Autotest Logs): New.

	at_top_builddir.
	* lib/autotest/general.m4 (AT_INIT): Compute srcdir,
	top_srcdir, builddir and top_builddir.

	$host' usage so people quit using `case $target' everywhere.

2001-11-22  Akim Demaille  <akim@epita.fr>

	* doc/autoconf.texi (Installation Directory Variables): Englishoes
	spotted by Jim Meyering.

2001-11-16  Paul Eggert  <eggert@twinsun.com>

	This patch implements a `long double' suggestion by Oliver Kiddle.

	* lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C)): Make the array
	static, to catch errors if the value isn't known at compile-time
	and the compiler supports dynamic arrays.  Change its name from
	`_array_' to `test_array' to avoid potential name clashes.
	(AC_C_LONG_DOUBLE): Make it a compile-time test, not a run-time
	test.  Do not define HAVE_LONG_DOUBLE if `long double' is no
	better than double.  Catch a bug in GCC 2.95.2 x86.
	* doc/autoconf.texi (C Compiler): Document the above.
	* NEWS: Likewise.

2001-11-13  Akim Demaille  <akim@epita.fr>

	* tests/m4sh.at (LINENO): Protect from autom4te's substitution by
	hand.
	* tests/tools.at: Don't protect dnl, AT_DATA_M4SH does.

2001-11-13  Akim Demaille  <akim@epita.fr>

	* lib/autotest/general.m4 (AT_INIT): After having run the test
	group, go back to the initial directory, not to at_suite_dir.

2001-11-13  Akim Demaille  <akim@epita.fr>

	* tests/atspecific.m4 (AT_DATA_M4SUGAR, AT_DATA_M4SH)
	(AT_DATA_AUTOCONF):  Also protect @&t@ from autom4te.
	(AT_CHECK_AUTOCONF, AT_CHECK_AUTOHEADER): Pass no --include
	option.
	(AT_CHECK_CONFIGURE): Use absolute paths.
	(_AT_CHECK_AC_MACRO): Create aclocal.m4 with AC_STATE_SAVE in it.
	The problem is still the old one: there is no means in M4 (that I
	know about) to create a defining macro, because there is no means
	to create `$1' etc., therefore, the defining macro ``swallows''
	all the arguments meant to the defined macro.

2001-11-13  Akim Demaille  <akim@epita.fr>

	* tests/atspecific.m4 (AT_DATA_AUTOCONF): New.
	(AT_CONFIGURE_AC): Output the definition of AC_STATE_SAVE in

	variable names when referring to a single test group, or to
	`suite' when referring to the whole test suite.
	`at_last_test' is removed: m4 compute at_format itself.
	(at_stdout, at_stder1, at_stderr): New variables.
	(AT_CHECK): Use them.

2001-11-13  Akim Demaille  <akim@epita.fr>

	* lib/autotest/general.m4 (AT_INIT): Be sure to put `.', relative,
	in PATH.
	Create `testsuite.dir/003/run' instead of `testsuite.003'.
	Do it as soon as a test fails, don't wait till the end of the test
	suite.
	Don't remove $as_me.[0-9]*, since these files no longer exist.

2001-11-13  Akim Demaille  <akim@epita.fr>

	* tests/tools.at: Use absolute paths, since we are no longer run
	in place.

2001-11-13  Akim Demaille  <akim@epita.fr>

	Now that tests are running in their own private dir, there is no
	need to list the files to remove at the end of tests groups.

	* lib/autotest/general.m4 (_AT_CLEANUP_FILE, AT_CLEANUP_FILES):
	(AT_data_files, at_data_files): Remove.
	(AT_CLEANUP, AT_DATA): Simplify.
	(AT_INIT): Adjust.
	Remove the group dir if !debug && !failed.
	* tests/atspecific.m4: Adjust.

2001-11-13  Akim Demaille  <akim@epita.fr>

	Start a new layout for Autotest: `testsuite' creates
	`testsuite.dir' in which the at-check-line etc. files are to be
	found, and `testsuite.dir/003' where the test group 3 is run.

	* lib/autotest/general.m4 (AT_INIT): at_tests_dir,
	at_check_line_file, at_format, at_test_normalized, at_group_dir
	are new variables.
	Create the directories.
	Use absolute paths for at- files.
	(AT_CHECK): Adjust.

2001-11-11  Michael Matz  <matz@kde.org>

	* m4sugar.m4 (_m4_foreach): Make it linear instead quadratic.
	(m4_car2): New.
	(m4_car): Properly quote arguments.

2001-11-13  Akim Demaille  <akim@epita.fr>

	* tests/aclocal.m4 (AC_STATE_SAVE): s/LIBOBJS/LIB@&t@OBJS/ to cope
	with stricter rules on LIBOBJS.

2001-11-12  Paul Eggert  <eggert@twinsun.com>

	* lib/autoconf/c.m4 (AC_C_PROTOTYPES): Define __PROTOTYPES too.

	* lib/autoconf/headers.m4, lib/autoconf/libs.m4,
	* lib/autoconf/programs.m4, lib/autoconf/specific.m4,
	* lib/autoconf/types.m4: When invoking AC_DEFINE and friends,
	specify to what the macro should be defined (typically to 1).

2001-11-12  Akim Demaille  <akim@epita.fr>

	* lib/autoconf/functions.m4 (AC_FUNC_STRTOD): AC_SUBST POW_LIB.
	From Jim Meyering.

2001-11-12  Akim Demaille  <akim@epita.fr>

	* lib/autoconf/programs.m4 (_AC_PROG_LEX_YYTEXT_DECL): Use
	AC_TRY_EVAL to run $LEX, not AC_TRY_COMMAND.  This validates the
	definition used by Automake where LEX is +/- "${missing} lex" and
	`missing' itself contains variables.

2001-11-12  Akim Demaille  <akim@epita.fr>

	* lib/autotest/general.m4 (AT_INIT): Push KILL at the end.
	Now that M4sh pushes BODY, the comments were output at the end of
	the test suites.

2001-11-08  Akim Demaille  <akim@epita.fr>

	* bin/autoreconf.in (&autoreconf): Run aclocal before tracing, so
	that we can trace macros from aclocal.m4.
	Trace AC_PROG_LIBTOOL, not AM_PROG_LIBTOOL, since the latter is
	obsoleted, and redirect to the former anyway.
	Reported by Ralf Corsepius.

2001-11-08  Akim Demaille  <akim@epita.fr>

	* bin/autoreconf.in (&autoreconf): AC_CONFIG_SUBIDRS are to be

	Don't look for aclocal flags if we already know aclocal is not
	used.
	Move aclocal.m4t only if it exists.
	Reported by Ezra Peisach.

	* bin/autoreconf.in (&parse_args): Work only on the configure.ac
	passed on command line, defaulting to ./configure.ac if present.
	(&maybe_autoreconf, File::Find): Remove, unused.
	(&autoreconf): If autoconf is not used, don't try to trace.

2001-11-02  Akim Demaille  <akim@epita.fr>

	* configure.ac: Bump to 2.52g.

2001-11-02  Akim Demaille  <akim@epita.fr>

	Version 2.52f.

	* config/config.guess, config/config.sub, doc/standards.texi:

	* bin/autoreconf.in (&autoreconf): Set `$aclocal_flags' to ''.
	Don't run aclocal when aclocal.m4 is not from aclocal.
	From Ezra Peisach.
	Don't run libtoolize and gettextize if --install is not given.

2001-11-01  Paul Eggert  <eggert@twinsun.com>

	* lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): _AS_CR_PREPARE needs to
	be invoked before _AS_LINENO_PREPARE.
	(_AS_LINENO_PREPARE): Use as_cr_digits and as_cr_alnum rather
	than character ranges.

	* lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Fix NLS before
	invoking AS_BASENAME.  Set the locale variables to 'C' if
	possible, as POSIX requires this to get the traditional
	behavior.
	* doc/autoconf.texi (Special Shell Variables): Describe the above.

2001-10-31  Paul Eggert  <eggert@twinsun.com>

	* lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): Do not surround body
	with {}, as that triggers a bug in Bash 2.05.

	(_AS_LINENO_PREPARE): Use Sed rather than
	Awk.  Fix the sed prepass to work even if there are multiple
	instances of $LINENO on the same line.  Do not substitute for
	other variables like $LINENOT.  Do not check file dates; such a
	check is unreliable on sufficiently fast machines, and removing
	the check makes the code simpler and more reliable.  Check for
	output and chmod failures.

	* doc/autoconf.texi (Special Shell Variables): Document
	the above.

2001-10-31  Akim Demaille  <akim@epita.fr>

	* configure.ac: Adjust.

2001-10-26  Paul Eggert  <eggert@twinsun.com>

	* NEWS, README, configure.ac, lib/Autom4te/General.pm,
	  lib/Autom4te/Struct.pm:
	Require Perl 5.005_03 instead of just 5.005, as some tests fail
	with 5.005_02.

	* doc/autoconf.texi (Special Shell Variables): Document some
	more LINENO gotchas, particularly with respect to the Awk+Sed hack.

	* lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): New macro.
	(_AS_LINENO_PREPARE): Use it instead of shell eval, since
	eval $LINENO is not portable in practice.

	Rename ac_cv_func_strerror_r_works to ac_cv_func_strerror_r_char_p,
	and rename HAVE_WORKING_STRERROR_R to STRERROR_R_CHAR_P, since
	POSIX decided to standardize on the int flavor of strerror_r.
	Always do char* test, as there's no reason not to.
	Assign to a char* var, to catch strerror_r that returns int*.

	* doc/autoconf.texi (Particular Functions):
	Document the above changes.  Also, document the fact that
	AC_FUNC_STRERROR_R defines HAVE_DECL_STRERROR_R.

	* NEWS: Mention HAVE_WORKING_STRERROR_R -> STRERROR_R_CHAR_P.

2001-10-20  Akim Demaille  <akim@epita.fr>

	* lib/m4sugar/m4sh.m4 (AS_DIRNAME): Use 'dirname' if that works.
	(AS_BASENAME_EXPR): New macro.
	(AS_BASENAME_SED): Do not assume GNU sed semantics.
	(AS_BASENAME): Use 'basename' if that works; then try 'expr';
	and fall back on 'sed' only if the other two fail.  This makes
	AS_BASENAME act more like AS_DIRNAME.
	(as_me): Shell-quote the argument of AS_BASENAME, in case $0
	contains white space.
	* lib/autoconf/general.m4 (_AC_INIT_SRCDIR):
	Use AS_DIRNAME, since I think it's now DOS-friendly.
	* tests/m4sh.at (DIRNAME_TEST): New arg $3.

2001-09-20  Tim Van Holder  <tim.van.holder@pandora.be>

	* doc/autoconf.texi (File System Conventions): Clarify the use of
	PATH_SEPARATOR.
	(Special Shell Variables[PATH_SEPARATOR]): Ditto.

2001-09-19  Akim Demaille  <akim@epita.fr>

	* lib/autotest/general.m4: Englishoes.

	(AC_LANG_INT_SAVE(C)): Also support negative values, down to LONG_MIN.

	* lib/autoconf/general.m4 (_AC_COMPUTE_INT_COMPILE):
	Do not pass a first argument with leading '-'
	to expr, by parenthesizing initial integers that might be negative.

	* doc/autoconf.texi (Particular Functions): AC_FUNC_GETPGRP
	now merely checks whether it is an error to pass an argument
	to getpgrp.

	* lib/autoconf/functions.m4 (_AC_FUNC_GETPGRP_TEST): Remove.
	(AC_FUNC_GETPGRP): Don't bother with a runtime test.  Just check
	whether it is a (compile-time) error to pass an argument to
	getpgrp.  This simpler test supports the revised documentation,
	and is all that AC_FUNC_GETPGRP's users really need.

2001-09-18  Akim Demaille  <akim@epita.fr>

	* doc/autoconf.texi (Limitations of Make) <$<>: New.

	correctly.
	Add test for AS_BASENAME.
	* lib/m4sugar/m4sh.m4: Fix AS_BASENAME so that it passes the previous
	added test. It now correctly handles /1/2/3/, returning '3' not ''.
	Added AS_BASENAME_SED to make the interface the same as AS_DIRNAME.
	* tests/base.at: Fixed the expected responses. The old ones were
	one line out...
	* lib/autoconf/general.m4: Fixed AC_PREFIX_PROGRAM, it now behaves as
	the documentation claims it should (and how it behaved in 2.13).

2001-09-18  Akim Demaille  <akim@epita.fr>

	* lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): No INIT-CMDS in

	No longer to be shipped.
	(version.in): Remove.

	Expect `package.m4' to define the package signature.
	* lib/autom4te.in (Autotest): Add `package.m4?'.
	* tests/Makefile.am (package.m4): New.
	* tests/suite.at: ifnames is a victim.

2001-09-18  Akim Demaille  <akim@epita.fr>

	* lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):
	Always include <stdio.h> and <stdlib.h>. Evaluate

	Reported by Wayne Chapeskie <waynec@spinnaker.com>.

2001-09-17  Paul Eggert  <eggert@twinsun.com>

	Fix bug reported by Paul Townsend on AIX 4.3.3.0 with CFLAGS=-O4
	or CFLAGS=-O5.  In that case, the linker has a relaxed view of
	fatal errors, and AC_CHECK_LIB causes it to include libraries even
	when they don't exist.

	* lib/autoconf/headers.m4 (AC_HEADER_DIRENT): Use AC_SEARCH_LIBS,
	not AC_CHECK_LIB, so that we don't use -ldir or -lx if we don't
	need it.

	* lib/autoconf/specific.m4 (AC_ISC_POSIX): Replace the old, crufty
	version with the version used by fileutils 4.1, except use
	AC_SEARCH_LIBS, not AC_CHECK_LIB, so that we don't use -lcposix if
	we don't need it.

	* doc/autoconf.texi (AC_ISC_POSIX): Describe new behavior.

2001-09-13  Akim Demaille  <akim@epita.fr>

2001-08-12  Alexandre Duret-Lutz  <duret_g@epita.fr>

	* tests/semantics.at (AC_C_BIGENDIAN): New test.

2001-08-11  Alexandre Duret-Lutz  <duret_g@epita.fr>

	* lib/autoconf/c.m4 (AC_C_BIGENDIAN): Handle ACTION-IF-TRUE,
	ACTION-IF-FALSE, and ACTION-IF-UNKNOWN.
	* doc/autoconf.texi (C Compiler Characteristics): Update

2001-08-11  Alexandre Duret-Lutz  <duret_g@epita.fr>

	* lib/autoconf/c.m4 (AC_C_BIGENDIAN): Guess endianness by grep'ing
	magic values from an object file when cross-compiling.
	Based on code by Guido Draheim <Guido.Draheim@gmx.de>.

2001-08-10  Akim Demaille  <akim@epita.fr>

	* bin/autom4te.in (&handle_output): Don't use `grep' with side
	effects.
	Suggested by Russ Allbery.

2001-08-10  Ralf Corsepius  <corsepiu@faw.uni-ulm.de>

	* lib/autoconf/general.m4 (_AC_OUTPUT_SUBDIRS): Propagate the
	current $prefix to the sub-configures.

2001-08-09  Tim Van Holder  <tim.van.holder@pandora.be>

	* lib/autoconf/lang.m4: Ignore *.xSYM when looking for an executable
	extension (needed on BeOS).  Reported by Guido van Rossum.

2001-08-09  Akim Demaille  <akim@epita.fr>

	* bin/autom4te.in ($icache): Load it only if older than autom4te.

2001-08-07  Akim Demaille  <akim@epita.fr>

	* lib/autotest/general.m4 (AT_INIT): All the `at-*' are to be
	removed.
	(at-setup-line): Huh?  Be a variable `at_setup_line', not a file.
	No need to remove the files before and after the each test, before
	each test and at the end of the suite is enough.
	Display only the children `times', not the shell's.
	If the test failed or was skipped, at-times is not available.

2001-08-07  Akim Demaille  <akim@epita.fr>

	Always produce testsuite.log, including when there are no
	failures.  This helps getting information on skipped tests, and
	duration of the tests.  Err, implement the latter btw.

	* lib/autotest/general.m4 (AT_INIT): Set up fd 6 for the log.
	Dump information on the first run of each test.
	(AT_CLEANUP): Create `at-times' containing the duration of the
	test group.

2001-08-07  Akim Demaille  <akim@epita.fr>

	The use of `dumpstat' revealed that `len' was used although it
	should not.  m4_text_wrap was using it, but in the Autoconf world
	where it is legal.  Hence (i) test M4sh in its own world, not
	Autoconf's, and (ii), ahem, fix the bug :)

	* lib/autotest/general.m4: Be sure the set good quotes, as tracing
	does not like `' instead of [].
	(AT_INIT): Forbid `^_?AT_'.
	And don't output such tokens.
	* tests/Makefile.am (CLEANFILES): Add `script', `script.s4g',
	`script.as', and `autom4te.cache'.
	Remove `empty' and `macro' which are no longer used.
	* tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): New.
	* tests/m4sugar.at: Use it.
	* lib/m4sugar/m4sugar.m4: Use `m4_len' not `len'.

2001-08-07  Akim Demaille  <akim@epita.fr>

	* bin/autoconf.in, bin/autoheader.in: --force, -f is a new option.

2001-08-07  Alexandre Duret-Lutz  <duret_g@epita.fr>

	* bin/autom4te.in (handle_output): Typo in quadrigraph substitution.

2001-08-04  Akim Demaille  <akim@epita.fr>

	* lib/autoconf/functions.m4 (AC_FUNC_ALLOCA, AC_FUNC_ERROR_AT_LINE)
	(AC_FUNC_FSEEKO, AC_FUNC_OBSTACK): Use AC_LANG_IFELSE, not
	AC_TRY_LINK.
	* lib/autoconf/headers.m4 (AC_HEADER_MAJOR): Likewise.
	* lib/autoconf/fortran.m4 (_AC_LANG_PROGRAM_C_F77_HOOKS)
	(AC_F77_MAIN): Likewise.

2001-08-04  Akim Demaille  <akim@epita.fr>

	Don't rely on M4sugar outputting the patterns in files, since we
	might process the output _without_ running m4, hence without these
	files.

	* lib/m4sugar/m4sugar.m4 (m4_init): No need for `m4_tmpdir'.
	* bin/autom4te.in (@Request::includes): Remove, unused.
	(@Request::source): Rename as...
	(@Request::input): this.
	(@preselect): Add `m4_pattern_forbid' and `m4_pattern_allow'.
	(&handle_output): Fetch the patterns from the traces.
	`$forbidden' and `$allowed' are constant: use m//o.
	(&handle_m4): M4sugar no longer wants `m4_tmpdir'.
	(m4_pattern_forbid, m4_pattern_allow): Adjust for tracing only.

2001-08-04  Akim Demaille  <akim@epita.fr>

	`autoconf && autoheader' is sped up.  Now, speed up `autoheader &&
	autoconf', i.e., in addition to caching traces, cache the output.

	* bin/autom4te.in (Request::cache): Rename as...
	(Request::id): this.
	($cache, $icache, $tcache, $ocache): New.
	(&handle_m4): Save M4 output in the cache instead of $tmp.
	(&handle_output): Adjust.
	(&up_to_date_p): Check that the output cache is up to date too.
	(top level): Run `&handle_m4' iff force or the cache is invalid.
	Run `&handle_output' if the output cache is more recent.

2001-08-04  Akim Demaille  <akim@epita.fr>

	* bin/autom4te.in ($force): New.
	(&parse_args, &print_usage): -f, --force is a new option.
	(&handle_output): CPP directives might have spaces after `#'.
	(&parse_args): The first file only can be frozen.

2001-08-04  Akim Demaille  <akim@epita.fr>

	Don't let autom4te compute the `include' traces several times:
	first check that the trace cache file is up to date, and then
	compare its timestamp with that of the output.

	* bin/autom4te.in, bin/autoupdate.in, bin/autoscan.in: Normalize
	the preamble.  Don't require 5.005 as Autom4te::General does it,
	and better yet (use `use', not `require'!).
	* lib/Autom4te/Struct.pm: Rename the last occurrences of
	Class::Struct as Autom4te::Struct.
	* lib/Autom4te/General.pm (File::stat): Use it.
	(&mtime): New, export it.
	* bin/autom4te.in: Use it.
	Declare `$req' is invalid if it is outdated.
	Don't declare it valid before saving it if something went wrong.

2001-08-04  Akim Demaille  <akim@epita.fr>

	Autom4te shall not encode Autoconf data, and preselecting traces
	must be proposed to the users.

	* bin/autom4te.in (@required_trace): Remove.
	(@preselect): New.
	(&parse_args, &print_usage): -p, --preselect is a new option.
	(&up_to_date_p): Adjust.
	* bin/autoconf.in: Preselect some Autoconf macros.

2001-08-04  Akim Demaille  <akim@epita.fr>

	* tests/tools.at (autoconf --trace: user macros): Check traces on

	Clean up the handling of the M4 builtins tracing exception.

	* bin/autom4te.in (Request::request): Don't complete M4 builtins
	trace requests.

	* lib/m4sugar/m4sugar.m4 (m4_init): Also forbid `_m4_*' tokens.
	(m4_divert_pop): Dump the whole diversion stack when a diversion
	mismatch happens.
	* bin/autom4te.in (&handle_output): Remember of the first
	occurrence of a possibly undefined macro, not the last.
	Complain about the possibly undefined macros in the same order as
	the appear in the output.
	* lib/autoconf/Makefile.am (autoconf.m4f): List its dependencies.
	* tests/tools.at (autoconf: forbidden tokens, basic)
	(autoconf: forbidden tokens, exceptions): No longer sort
	autoconf's stderr, as it is now deterministic.
