116 Before using /dev/full, check that it is a writable character
118 Report by Benoit Sigoure and Eric Blake.
120 Actually test that @configure_input@ is expanded correctly.
121 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
122 Actually check generated file contents for the name of the
123 generated file, using AC_PROG_FGREP and $FGREP.
125 2008-03-01 Benoit Sigoure <tsuna@lrde.epita.fr>

132 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
133 Cover more potentially problemtic file names. Use the new
136 Properly handle funny file names for headers in config.status.
137 The test suite did not cover this bug because the code was not
138 quoting properly the arguments of `rm -f' (which "fails" silently)
139 as well as the arguments of `diff' (whose output was redirected to
140 /dev/null so we couldn't see its error message).
141 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Properly quote the
142 file names passed to `rm' and `diff'.
143 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):

244 Reported by Ralf Wildenhues.
246 Document grep peculiarity.
247 * doc/autoconf.texi (Limitations of Usual Tools) <grep>: Document
248 BSD behavior on binary input.
250 Minor testsuite improvements.
251 * lib/autotest/general.m4 (AT_INIT) <PREPARE_TESTS>: Use fewer
252 forks when sanitizing PATH. Always output machine information,
253 not just when atconfig was located.
255 Add 'testsuite -C dir'.
256 * lib/autotest/general.m4 (_AT_ARG_OPTION): Move missing argument
258 (AT_INIT) <PARSE_ARGS_END>: ...here, since -k always takes
260 <DEFAULTS>: Delay computation of variables based on $at_dir...
261 <PREPARE_TESTS>: ...to here, since -C can change $at_dir.
262 <TESTS>: Re-invoke via absolute name, since -C may be in effect.
263 <PARSE_ARGS>: Parse new option.
264 <HELP_TUNING>: Document it.
265 * tests/autotest.at (Choosing where testsuite is run): New test
267 (Keywords and ranges): Add test for missing -k argument.

274 build-aux/texinfo.tex: Sync from gnulib.
275 * doc/fdl.texi, doc/make-stds.texi, doc/standards.texi:
278 2008-01-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
280 * doc/autoconf.texi (Particular Programs): Do not mention the
281 Autoconf version in which the AC_PROG_INSTALL change was done.
282 Suggested by Paul Eggert.
284 2008-01-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
286 Fix --help=recursive with multiple AC_CONFIG_SUBDIRS.
287 * lib/autoconf/general.m4 (_AC_INIT_HELP): If, for recursive help
288 mode, we change to the source directory, also set $ac_pwd so we
289 do not go back to the build tree for the next config subdir.
290 * tests/torture.at (Deep Package): Extend test to contain two
291 config subdirs on the top level.
293 Fix parallel `maintainer-check'.

324 * tests/Makefile.am (noinst_SCRIPTS): Renamed from
325 check_SCRIPTS. Building the wrappers for `all' allows help2man
326 to use them for the manpages.
327 Report by Benoit Sigoure.
329 * bin/autoreconf.in: Discard stderr for $autoconf/$aclocal --help.
331 2007-12-16 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

335 upon write failures for --help, --version, --list.
336 Guard against write failures for intermediate created scripts.
337 <at_func_create_debugging_script>: Do not make the debugging

340 2007-12-12 Eric Blake <ebb9@byu.net>
342 Fix thinko in earlier patch - m4_join isn't defined yet.
343 * lib/m4sugar/m4sugar.m4 (m4_expansion_stack_push, _m4_defun_pro)
344 (_m4_defun_pro_outer, _m4_defun_epi, _m4_defun_epi_outer)
345 (m4_require): Use m4_do, not m4_join.
347 Fix some whitespace tests on cygwin.

349 font-lock. Create $TMPDIR before it might be used.
351 Fix spurious testsuite failure with M4 1.4.11.
352 * tests/local.at (AT_CHECK_M4): Cater to new m4 error message.
355 * lib/m4sugar/m4sugar.m4 (m4_expansion_stack_push, _m4_defun_pro)
356 (_m4_defun_pro_outer, _m4_defun_epi, _m4_defun_epi_outer)
357 (m4_require): Avoid extra macro calls.
359 2007-12-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
361 * tests/torture.at (srcdir): Fix quoting.
363 Do not pass top_srcdir to configure scripts in testsuite.
364 * tests/autotest.at (srcdir propagation): Copy install-sh to
366 (my only test): Drop setting of `top_srcdir'.
367 * tests/base.at (Input/Output): Likewise.
368 * tests/local.at (AT_CONFIGURE_AC): Copy install-sh,
369 config.guess, and config.sub to test source tree.
370 Drop AC_CONFIG_AUX_DIR setting.
371 (AT_CHECK_CONFIGURE): Drop setting of `top_srcdir'.
372 * tests/torture.at (Substitute a 2000-byte string): Drop
373 AC_CONFIG_AUX_DIR setting, copy install-sh to test source tree.
374 (Substitute a newline, datarootdir workaround): Likewise.
375 (Define a newline): Adjust for linenumber changes in configure.ac.
376 * tests/foreign.at (Libtool): Adjust comment to reflect changes.
378 * tests/semantics.at (AC_PATH_PROGS_FEATURE_CHECK): Skip test
379 if `pwd` contains whitespace.
381 Quote $abs_top_srcdir in tests.
382 * tests/local.at (AT_CHECK_PERL_SYNTAX): Likewise.
383 * tests/tools.at (Syntax of the shell scripts): Likewise.
385 * tests/m4sh.at (LINENO): Quote $0.
387 Fix testsuite program wrapper for whitespace in `pwd`.
388 The problem here is that the usual mantra is that command
389 variables can contain arguments, thus we cannot just escape
390 $AUTOCONF, $AUTOM4TE etc. The compromise is to put the
391 $top_builddir/tests directory early in $PATH, so that the
392 wrappers are found by their plain name.
393 * tests/wrapper.as: Put $testdir early in $PATH.
394 (AUTOCONF, AUTOHEADER, AUTOM4TE): Set to plain command names.
396 Proper config.status --file/--header and $srcdir escaping.
397 * lib/autoconf/status.m4 (_AC_OUTPUT_MAIN_LOOP): Quote special
398 characters in $ac_file_inputs.
399 (_AC_OUTPUT_FILE, _AC_OUTPUT_HEADER): eval $ac_file_inputs

402 (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS): Extend test.
404 Fix Autotest for whitespace in `pwd`.
405 * lib/autotest/general.m4 (AT_INIT)
406 <at_func_create_debugging_script, Driver Loop>:
408 * tests/autotest.at (whitespace in absolute testdir): New test.
410 * lib/autom4te.in: Quote @datadir@.
412 Proper file name escaping in Autoconf programs and Perl modules.
413 This includes escaping of characters special to the shell
414 as well as special to Perl, e.g., leading `<' or `>'.
415 For example, when $file starts with `>', `open ">$file"'
416 wrongly tries to append to a different file.
417 * bin/autoconf.as: Fix quoting for autom4te options.
418 * lib/Autom4te/General.pm (shell_quote): New function, taken
419 from coreutils, written by Jim Meyering.
421 * bin/autom4te.in (files_to_options, handle_m4): Use shell_quote
423 * bin/autoreconf.in (parse_args): Likewise.
424 * bin/autoscan.in (main): Likewise.
425 * bin/autoupdate.in (main): Likewise.
426 * bin/autoheader.in: Likewise, fixing old insufficient escaping.
427 * bin/ifnames.in: Likewise, XFile usage fixes.
428 * tests/tools.at (autom4te and whitespace in file names): Extend
429 test. Test twice, with special characters allowed on w32, and the
430 rest. Test leading and trailing whitespace, for `open_quote'.
431 (autotools and whitespace in file names): New, analogous test.
432 Reported by Paul Eggert and Benoit Sigoure, additional suggestions
433 by Russ Allbery and Eric Blake.
436 * lib/Autom4te/Channels.pm, lib/Autom4te/Configure_ac.pm,
437 lib/Autom4te/Struct.pm, lib/Autom4te/XFile.pm: Likewise.
438 * lib/Autom4te/FileUtils.pm (open_quote): New function.
439 (update_file, contents): Use it.
441 * Makefile.am (autom4te-update): Rewrite for git.
443 2007-12-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
445 * doc/autoconf.texi (autom4te Invocation, Autom4te Cache): Fix typos.
448 * Makefile.am, doc/install.texi, lib/autoconf/fortran.m4,
449 lib/autoconf/lang.m4, lib/freeze.mk: Likewise.
451 2007-12-04 Eric Blake <ebb9@byu.net>
453 Manually resync with gnulib, since 'make cvs-update' no longer works.
454 * build-aux/config.guess: New upstream version.
455 * build-aux/config.sub: Likewise.
457 When using older automake, don't downgrade build-aux/texinfo.tex.
458 * configure.ac (AM_INIT_AUTOMAKE): Add no-texinfo.tex option.
459 * doc/Makefile.am (TEXINFO_TEX): Add.
461 2007-11-27 Paul Eggert <eggert@cs.ucla.edu>
463 Fix AC_C_BIGENDIAN bug caused by new awk method of substitution.
464 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Don't comment out the
465 #undef as this runs afoul of our new way of creating config.h.
466 Problem reported by Jim Meyering in
467 <http://lists.gnu.org/archive/html/autoconf-patches/2007-11/msg00164.html>.
469 2007-11-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
471 Fix autom4te for unusual characters in input file names.
472 * bin/autom4te.in (files_to_options): Quote active characters
474 * tests/tools.at (autom4te and white space in file names):
477 * doc/autoconf.texi (Limitations of Usual Tools) <awk>:
478 Document that Tru64 awk always splits $0.
480 2007-11-24 Stepan Kasal <kasal@ucw.cz>
482 * lib/autotest/general.m4 (AT_INIT): Do not extract the
483 `#AT_STOP_...' line at the end of each test.
485 2007-11-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
487 * lib/autotest/general.m4 (AT_INIT): For awk line number
488 extraction script, ensure `$at_group' has a defined value
489 even for the empty set, and properly quote its usage inside
492 2007-11-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
494 * doc/autoconf.texi (Shell Functions): New chapter. Document
495 IRIX sh $0 issue in functions, move content from ...
496 (Portable Shell): ... here.
497 (Shell Script Compiler): Note that shell functions are not
498 totally unportable any more.
500 2007-11-22 Stepan Kasal <kasal@ucw.cz>
501 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
503 * lib/autotest/general.m4 (AT_INIT): Exit awk script after
504 extracting the line numbers of the last needed test.
506 2007-11-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
508 * lib/autotest/general.m4 (AT_INIT) <at_func_create_debugging_script>:
511 2007-11-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
513 Fix IRIX testsuite debugging failures: $0 in functions.
514 * lib/autotest/general.m4 (AT_INIT) <at_func_create_debugging_script>:
515 Do not use $0 inside a function, as IRIX sh will set that to the
516 function name rather than the script invocation name.
518 2007-11-19 Paolo Bonzini <bonzini@gnu.org>
519 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
521 * lib/autotest/general.m4 (at_func_test): Use cached line numbers
522 to extract test scripts.
523 (AT_INIT): Extract and cache test script line numbers.
525 2007-11-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
527 * lib/autotest/general.m4: Revert 2007-11-15 patch and
528 subsequent fixups; the awk -> here-document conversion trashes
529 performance too much with AIX sh.
531 2007-11-18 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
533 * tests/local.at: Do not test m4, perl with AT_TESTED.
535 Diagnose and guard against write errors dealing with config.status.
536 The general idea is this: all write failures from `configure'
537 writing `config.status' are indicated by $ac_write_error, which
538 is only checked at the end. This is safe because config.status
539 code is not executed before the file is complete. Other write
540 failures, be they inside config.status, or in sub shell/awk
541 scripts spawned from configure or config.status, typically need
542 earlier checking, as their results are used right afterwards.
543 * lib/autoconf/status.m4 (AC_OUTPUT): Initialize `ac_write_fail'
544 before writing config.status, check afterwards.
545 (_AC_OUTPUT_FILES_PREPARE, _AC_OUTPUT_FILE)
546 (_AC_OUTPUT_HEADERS_PREPARE,_AC_OUTPUT_CONFIG_STATUS):
547 Set `ac_write_error' for write failures to config.status. Barf
548 upon write failures to temporary files.
549 Adjust note about closing and reopening the here-document.
550 (_AC_OUTPUT_HEADER, _AC_OUTPUT_LINK, _AC_OUTPUT_COMMAND)
551 (_AC_OUTPUT_MAIN_LOOP): Likewise, adjust note about closing and
552 reopening the here-document.
553 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
554 Ensure `ac_write_error' does not escape into config.status.
555 Also, add a couple of code paths not yet exercised in the test
556 suite: a config file with input from stdin, and a config header

562 Avoid error with Tru64 awk and testsuite lines with many words.
563 * lib/autotest/general.m4 (AT_INIT): In the awk script that
564 reads the testsuite, set the field separator to an unusual value,
565 in order to not run over the limit of 199 fields. Tru64 4.0D awk
566 even splits the input if $i, i>0, was never accessed in the script.

604 2007-11-15 Paolo Bonzini <bonzini@gnu.org>
605 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
607 * lib/autotest/general.m4 (at_func_test): Remove.
608 (AT_INIT): Pre-extract test groups into separate files.
609 (AT_CLEANUP): Source pre-extracted file instead of calling at_func_test.
610 Remove at-test-source files together with the $at_group_dir.
611 * tests/autotest.at (Long test source lines): New test.

630 2007-11-13 Jim Meyering <meyering@redhat.com>
632 Clean up the rule to create "expr".
633 * tests/Makefile.am (expr): Don't redirect directly to target.
634 Redirect just once, not for each echo statement.
635 Use $@, not literal "expr".
637 2007-11-13 Paul Eggert <eggert@cs.ucla.edu>
639 Don't worry about preprocessor when testing long long.
640 See: http://lists.gnu.org/archive/html/bug-gnulib/2007-11/msg00075.html

642 (AC_TYPE_LONG_LONG_INT, AC_TYPE_UNSIGNED_LONG_LONG_INT):
643 These no longer check for preprocessor flaws.
644 * lib/autoconf/types.m4 (_AC_TYPE_LONG_LONG_SNIPPET):
645 Do not check for preprocessor flaws.
647 2007-11-13 Jim Meyering <meyering@redhat.com>
649 Adapt dependencies, now that a version change doesn't modify configure.ac
650 * GNUmakefile: Remove "make clean" kludge.

670 2007-11-12 Jim Meyering <meyering@redhat.com>
672 Add more non-srcdir build support.
673 * GNUmakefile (dummy): Split a long line.
674 Add -v option to autoreconf invocation.
676 Remove the autoreconf-provided INSTALL, so that we regenerate it.
677 * GNUmakefile (dummy): Remove INSTALL.
679 Remove racy commands to build scripts in bin/ and tests/.
680 * man/Makefile.am (.x.1): Now that scripts in bin/ and tests/
681 are guaranteed to be built, remove the rules that tried to build
682 them. Before, with a parallel build, these rules could lead to
683 two processes writing tests/wrapper.in concurrently.
685 Build in man/ only *after* building in bin/ and tests/.
686 * Makefile.am (SUBDIRS): The man-page-creation process runs $(MAKE)
687 in both bin/ and tests/.
689 Accommodate non-srcdir build-from-checkout.
690 * build-aux/git-version-gen: Require an additional parameter: $srcdir.
691 Use git's --git-dir=$srcdir/.git option.
692 Add quotes, in case tarball_version_file contains shell meta-characters.
693 * GNUmakefile (_curr-ver): Pass $(srcdir) to git-version-gen.
694 * configure.ac: Pass "." to git-version-gen.
696 Avoid spurious test failures due to version skew.
697 * GNUmakefile (dummy): Run $(MAKE) clean after autoreconf -i.

724 2007-11-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
726 Ignore configure --help* errors due to LINENO-impaired shells.
727 * tests/torture.at (Configuring subdirectories, Deep Package):
728 In the --help* tests in read-only trees, make `.' temporarily
729 writable again for the `stderr' file, and ignore errors due to
730 the attempt to write configure.lineno.
731 Report by Patrick Welche.
733 2007-11-10 Jim Meyering <meyering@redhat.com>
735 Generate package.m4 in build-dir, not srcdir.
736 * tests/Makefile.am (package.m4): Adjust target.
737 Don't redirect directly to $@.
738 (CLEANFILES): Add package.m4.
739 ($(TESTSUITE)): Depend on just-built package.m4, not the one
741 When running $(AUTOTEST), search "." before searching $(srcdir).
743 Avoid a race condition that would make parallel "distclean" fail.
744 * tests/Makefile.am (distclean-generic): Replace the default,
745 automake-provided rule with an identical one, but with an additional
746 dependency on distclean-local. Simply adding the dependency would
747 cause automake not to emit the rule at all.
748 * BUGS: Building with -jN works, now.
750 Distribute git-version-gen.
751 * Makefile.am (EXTRA_DIST): Add build-aux/git-version-gen,
752 since GNUmakefile is distributed, and requires it for dist* rules.
754 Remove two more generated files from version control.
755 * INSTALL: Remove generated file.
756 * lib/autoscan/autoscan.list: Remove generated file.
758 2007-11-09 Paul Eggert <eggert@cs.ucla.edu>
760 * GNUmakefile (PATH): Remove stray apostrophes; they become
761 part of PATH, which isn't wanted here.
763 2007-11-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
765 New config files output variable `top_build_prefix'.

768 * doc/autoconf.texi (Preset Output Variables): Document it.
770 Report by Bob Friesenhahn.
772 Avoid expr for arithmetic evaluation if the shell accepts $((...)).
773 * lib/autotest/general.m4 (AT_INIT) <at_func_arith>: New
774 function, to parametrize arithmetic with expr vs. the shell.
775 Use it where possible.
776 Suggestion by Benoit Sigoure.
778 2007-11-03 Benoit Sigoure <tsuna@lrde.epita.fr>
780 Adjust the documentation of autotest WRT atlocal.
781 * doc/autoconf.texi (Making testsuite Scripts): It is not necessary,
782 when using Automake, to write a rule to produce atlocal, since it's
783 an AC_CONFIG_FILES. Mention that atlocal.in needs to be
784 distributed, not atconfig.in.
786 2007-11-04 Eric Blake <ebb9@byu.net>
788 Update list information.
789 * README: Mention new autoconf-commit list.

804 s/-/./ in snapshot version string: 2.61a-256-8b556 -> 2.61a.256-8b556
805 * build-aux/git-version-gen: This syncs from coreutils.
807 Adjust the build procedure so "make check" works reliably.
808 * README-hacking: Include an extra step between "make" and
809 "make check" to ensure that the latter passes.
811 Use just-built tools, when possible.
812 * GNUmakefile (PATH): Set and export here, ...
813 (dummy): ... rather than here.

851 Suggestion from Ralf Wildenhues.
853 2007-11-03 Eric Blake <ebb9@byu.net>

865 extracted from AC_TYPE_LONG_LONG_INT and AC_TYPE_UNSIGNED_LONG_LONG_INT.
866 (AC_TYPE_LONG_LONG_INT, AC_TYPE_UNSIGNED_LONG_LONG_INT): Use it.
867 Fixes problem with Sun C 5.[0-8] in 32-bit mode, reported in

869 Suggested by Paul Eggert.
871 2007-10-28 Jim Meyering <meyering@redhat.com>
873 * README-hacking: Autoconf, Automake, and Perl are required to build.
874 List Gzip and Tar separately. Suggested by Ralf Wildenhues.
876 2007-10-28 Jim Meyering <meyering@redhat.com>
878 README-hacking: Recommend running autoreconf -vi.
879 * GNUmakefile (dummy): Use autoreconf -i, with appropriate PATH,
880 so that we use just-built tools when they're available.
881 Suggestions from Ralf Wildenhues.
883 2007-10-28 Jim Meyering <meyering@redhat.com>
885 Make inter-release --version output more useful.
887 Now, each unofficial build has a version "number" like 2.61a-19-58dd,
888 which indicates that it is built using the 19th change set
889 (in _some_ repository) following the "v2.61a" tag, and that 58dd
890 is a prefix of the commit SHA1.
891 * build-aux/git-version-gen: New file.
892 * configure.ac: Run it to set the version.
893 (AM_INIT_AUTOMAKE): Don't check NEWS here.
894 * Makefile.am (dist-hook): Arrange so that .version appears only
895 in distribution tarballs, never in a checked-out repository.
896 * .gitignore: Add .version here, too. Just in case.
897 * tests/Makefile.am ($(srcdir)/package.m4): Depend on Makefile,
898 not configure.ac, now that the version number changes automatically.
900 Ensure that $(VERSION) is up to date for dist-related targets.
901 * GNUmakefile: Arrange to rerun autoconf, if the version reported by
902 git-version-gen doesn't match $(VERSION), but only for dist targets.
904 2007-10-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

2051 2007-05-21 Paul Eggert <eggert@cs.ucla.edu>
2053 * lib/autoconf/c.m4 (AC_OPENMP): Don't echo --enable-openmp
2054 choice, since that's what we do with --enable-largefile etc.

2056 the parens work with Emacs.
2058 * doc/autoconf.texi (Generic Compiler Characteristics): Fix typo

2141 * doc/autoconf.texi (Particular Programs): Typo
2142 @acindex{AC_PROG_MKDIR_P} shouldn't have "AC" in that call.
2144 2007-04-30 Paul Eggert <eggert@cs.ucla.edu>
2146 * lib/m4sugar/m4sh.m4 (_AS_SHELL_FN_SPY): Don't imply that
2147 'configure' will fail if the shell lacks proper support for shell

2158 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't look
2159 for a.* when searching for executables, as this prevents users
2160 from having files like a.c. Problem reported by Ralf Wildenhues in:

2172 * NEWS: Document recent changes to AC_CHECK_ALIGNOF, AC_CHECK_SIZEOF,
2173 AC_CHECK_TYPE, AC_CHECK_TYPES.
2174 * doc/autoconf.texi (Generic types): C types must be type-names
2175 (the C terminology), not type-ids (the C++ term). C++ types
2176 must not be anonymous.
2177 * lib/autoconf/types.m4 (_AC_CHECK_TYPE_NEW): Remove special case
2178 for C++; this drops support for anonymous struct and union types,
2179 which were problematic anyway.

2198 with objects too. Document the restrictions on its use.
2199 Document the restrictions on AC_CHECK_ALIGNOF's type argument.
2200 * lib/autoconf/types.m4 (_AC_CHECK_TYPE_NEW):
2201 For C, just try sizeof (TYPE) and sizeof ((TYPE)); if the former
2202 works but the latter doesn't, then it's a valid type.
2203 This lets people use function types and so forth.
2204 For C++ there doesn't seem to be a simple solution, so leave it alone.
2205 (AC_CHECK_SIZEOF): Allow argument to be a variable.
2206 (AC_CHECK_SIZEOF, AC_CHECK_ALIGNOF): Don't bother to invoke
2207 AC_CHECK_TYPE; that wasn't documented or necessary.
2209 2007-04-11 Stepan Kasal <kasal@ucw.cz>
2211 * lib/autoconf/general.m4 (_AC_LINK_IFELSE): Skip AS_TEST_X

2260 nonstandard grep R.E. escape sequences.
2262 2007-03-17 Jim Meyering <jim@meyering.net>
2264 * doc/autoconf.texi: Adjust grammar around use of "heuristics".
2265 (Limitations of Usual Tools): Also list \< and \>, and mention that
2266 HP-UX's grep, like the one from Solaris, does not support that syntax.
2268 2007-03-09 Stepan Kasal <kasal@ucw.cz>
2270 * doc/autoconf.texi (Specifying Names): `--host' does not
2271 change the build type.

2378 AC_SUBST([MKDIR_P]), so that Automake < 1.10 will pick up its
2379 trace, if a package uses AC_PROG_MKDIR_P explicitly. The actual
2380 substitution will still be done by the special code.

2404 * lib/autoconf/programs.m4 (AC_PROG_SED): When closing a pipe
2405 early on the reader side, drop stderr of the input to avoid

2425 discussion about the allow_superuser_privileges example,
2426 and change it a bit to make things clearer.
2427 (Optimization and Wraparound): Clarify whether the compiler
2428 will generate an infinite loop for the example derived from
2429 Autoconf's mktime test.
2430 (Signed Overflow Advice): Say that -ftrapv is meant for debugging.
2431 Also, clarify unsigned multiplication overflow.
2433 2007-01-04 Eric Blake <ebb9@byu.net>
2435 * bin/Makefile.am (RELEASE_YEAR): New macro.

2447 * doc/autoconf.texi (Integer Overflow): Revised based on today's
2448 feedback. The most important changes document what happens when
2449 you convert an out-of-range value to a signed integer type, and
2450 say that (sum < a) != (b < 0) reliably detects overflow when sum =
2453 * doc/autoconf.texi (Integer Overflow): Greatly expand and
2454 rewrite, taking notions from the recent discussion on the gcc and
2455 autoconf mailing lists; please see
2456 http://lists.gnu.org/archive/html/autoconf-patches/2006-12/msg00091.html
2457 and follow the many links.
2458 (Integer Overflow Basics, Signed Overflow Examples):

2460 (Signed Integer Division): New sections.
2462 2006-12-28 Steven G. Johnson <stevenj@alum.mit.edu>
2464 * lib/autoconf/general.m4 (AC_DEFINE_TRACE): Don't include
2465 preprocessor macro arguments in traced name.
2466 * doc/autoconf.texi (Defining symbols): Document longstanding
2467 support for AC_DEFINE-ing macros with arguments, and document
2468 behavior when the same variable has multiple AC_DEFINEs.
2469 * lib/autoconf/fortran.m4 (_AC_FC_WRAPPERS): Revert to the
2470 old implementation which AC_DEFINEs the FC_FUNC and FC_FUNC_
2471 macros directly, giving much shorter and simpler code.
2473 2006-12-28 Malcolm Purvis <malcolmp@xemacs.org> (trivial change)
2475 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Insert a
2476 space before "$ac_configure_args" to prevent a 'config.status
2477 --recheck' failure if ac_configure_args doesn't contain a leading
2478 space. This works around a problem with the XEmacs configure.ac,
2479 which uses the (undocumented) ac_configure_args variable
2480 inconsistently with Autoconf.
2482 2006-12-22 Paul Eggert <eggert@cs.ucla.edu>
2484 * lib/autoconf/functions.m4 (AC_FUNC_MKTIME):
2485 Include <limits.h>, and use its INT_MAX to rewrite the
2486 j loop so that it does not overflow 'int'. Problem reported by
2488 <http://lists.gnu.org/archive/html/bug-gnulib/2006-12/msg00084.html>.
2489 Play it safe by shifting left by 1 rather than multiplying by 2,
2490 as GCC is less likely to optimize this away when the value
2491 is signed (when it assumes overflow leads to undefined behavior).
2492 Also, don't assume time_t uses two's complement.
2494 2006-12-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2496 * tests/torture.at (Substitute a 2000-byte string): Avoid using
2497 a 10kB long (multi-line) string literal, OpenServer 5.0.7 ksh
2498 dumps core on it. Report by Tim Rice.

2517 (External Software, Package Options): Cross-reference to Option
2518 Checking, and use this to shorten our section.
2519 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Prefer test -n
2520 "$x" to test "x$foo" != x.

2524 ac_unrecognized_opts to the empty string.
2525 Don't echo the unrecognized opts, as this might mishandle
2526 backslashes or leading -.
2527 (AC_PRESERVE_HELP_ORDER): Put the --disable-option-checking
2528 usage next to the other --disable-FEATURE options in the
2531 2006-12-18 Steven G. Johnson <stevenj@alum.mit.edu>
2533 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS, _AC_INIT_PARSE_ARGS):
2534 (_AC_INIT_PARSE_ENABLE2, _AC_INIT_HELP, _AC_ENABLE_IF):
2535 Print warning for unrecognized --with and --enable options
2536 (AC_DISABLE_OPTION_CHECKING): New macro to disable warnings.
2537 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS, _AC_OUTPUT_SUBDIRS):
2538 Disable option checking when subdirs are configured.
2539 (AC_OUTPUT): If warnings are enabled, print warning about
2540 unrecognized --with and --enable options at the end of
2541 the configure output (as well as at the beginning).
2542 * doc/autoconf.texi (Option Checking): New node.
2543 Document new option warning functionality.
2545 2006-12-16 Eric Blake <ebb9@byu.net>
2547 * configure.ac (AC_INIT): Bump version, since 2.61a is released.
2548 * NEWS: Start news for current version.
2550 2006-12-15 Paul Eggert <eggert@cs.ucla.edu>
2552 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT):
2553 Define HAVE_GETMNTENT to 1, not to the empty string.
2554 Problem originally reported by Jochen Friedrich in
2555 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=403243>.
2557 This change prompted by a problem report by Andrey Simonenko in
2558 <http://lists.gnu.org/archive/html/bug-autoconf/2006-12/msg00026.html>.
2559 * doc/autoconf.texi (Defining Symbols): AC_DEFINE works for
2560 object-like macros only, in the traditional portable character
2562 * lib/autoconf/general.m4 (AC_DEFINE_TRACE_LITERAL):
2563 Warn about attempts to define things that are not identifiers.
2564 * lib/autoconf/fortran.m4 (_AC_FC_WRAPPERS): Rewrite to avoid
2565 awful hack that AC_DEFINEd macro names containing parentheses.
2567 2006-12-12 Paul Eggert <eggert@cs.ucla.edu>
2569 * doc/autoconf.texi: Undo some of the 2006-12-10 change. It was
2570 too drastic, even if Texinfo in theory requires it for info mode.
2572 (config.status Invocation): Renamed back from Recreating a
2574 (Obsolete config.status Use): Renamed back from Obsolete Recreation.
2575 (Autoconf 2.13): Renamed back from 20th-century Autoconf 2.
2577 2006-12-11 Paul Eggert <eggert@cs.ucla.edu>
2579 * NEWS: Version 2.61a.
2581 2006-12-11 Paul Eggert <eggert@cs.ucla.edu>
2582 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2584 * NEWS: Document changes with echo and printf, and the lack
2585 of limits on the total size of multi-line values of substituted
2586 variables, and the AC_FUNC_FSEEKO fix.
2588 2006-12-10 Paul Eggert <eggert@cs.ucla.edu>
2590 * doc/autoconf.texi (Writing Autoconf Input): Renamed from
2591 Writing configure.ac.
2592 (Autoconf Input Layout): Renamed from configure.ac Layout.
2593 (Recreating a Configuration): Renamed from config.status Invocation.
2594 (Obsolete Recreation): Renamed from Obsolete config.status Use.
2595 (acconfig Header): Renamed from acconfig.h.
2596 (20th-century Autoconf 2): Renamed from Autoconf 2.13.
2597 (Writing Testsuites): Renamed from Writing testsuite.at.
2598 (Autom4te Cache): Renamed from autom4te.cache.
2600 * BUGS: Remove mention of VPATH problem, since it's now documented
2601 not to be a bug in the Autoconf build procedure itself, but rather
2602 a problem with the proprietary `make' programs.
2604 * doc/autoconf.texi (Build Directories): Add a cross reference
2607 * build-aux/config.guess, build-aux/config.sub, build-aux/texinfo.tex:
2608 * doc/standards.texi: Sync from gnulib.
2610 * man/autoconf.1, man/autoheader.1, man/autom4te.1, man/autoreconf.1:
2611 * man/autoscan.1, man/autoupdate.1, man/config.guess.1:
2612 * man/config.sub.1, man/ifnames.1: Remove from CVS, since they're
2613 generated automatically.
2615 2006-12-06 Paul Eggert <eggert@cs.ucla.edu>
2617 * lib/autoconf/c.m4 (_AC_PROG_CC_C89): Also try -xc99=all, for Sun
2618 C 5.8 on Solaris 10. Using -xc99=all rather than -xc99 bypasses
2619 the buggy -xc99 option of Forte Developer 7 C on Solaris 9.
2621 2006-12-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2623 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Drop the
2624 `CEOF$ac_eof' special marker, the awk script cannot contain a
2625 line matching `^CEOF', so this is not needed any more.
2626 * tests/torture.at (Substitute a newline): Expose the `%!_!# '
2627 special marker in the test.
2629 2006-12-06 Stepan Kasal <kasal@ucw.cz>
2631 * tests/tools.at (autom4te preselections): Use `find -newer';
2632 remove one of the sleeps.
2634 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE): Make it
2635 more readable, using ...
2636 (_AC_INIT_PARSE_ENABLE2): ... this new helper macro.
2638 * doc/autoconf.texi (autoheader Invocation): Do not double-
2639 quote the parameter of `AH_BOTTOM' in the example.
2641 2006-12-05 Stepan Kasal <kasal@ucw.cz>
2643 * doc/autoconf.texi (Configuration Headers): Remove the
2644 example with multiple input files.
2645 (autoheader Invocation): Encourage `AH_BOTTOM', discouraging
2646 multiple input files.
2648 2006-12-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2650 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): When
2651 creating the awk substitution script, handle one input line at a
2652 time, so that the maximum length of a substituted (multi-line)
2653 value is not limited by the size of the sed pattern space.
2654 The trade-off is a slightly repetitive sed script.
2655 * doc/autoconf.texi (Limitations of Usual Tools): Branch labels
2656 can only have up to 7 characters, due to Solaris 10 /bin/sed.
2657 * tests/torture.at (Substitute a 2000-byte string): Increase the
2658 test with several long lines, they should not be caught by sed
2661 * tests/tools.at (autom4te preselections): New test, to flag
2662 entries missing from autom4te.cfg.
2663 Report by David Byron <dbyron@hheld.com>.
2665 * tests/torture.at (Substitute a 2000-byte string): Actually use
2666 AC_PROG_AWK, so the last change works as intended.
2667 (Substitute and define special characters): Likewise.
2668 (Substitute a newline): Likewise.
2670 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Use `$AWK'
2671 instead of `awk' consistently.
2672 (_AC_OUTPUT_CONFIG_STATUS): Initialize $AWK.
2673 * tests/torture.at (Torturing config.status): Test both the
2674 result of AC_PROG_AWK and plain awk.
2675 (Substitute a 2000-byte string): Likewise.
2676 (Substitute and define special characters): Likewise.
2677 (Substitute a newline): Likewise.
2679 2006-12-04 Paul Eggert <eggert@cs.ucla.edu>
2681 * lib/autoconf/functions.m4 (AC_FUNC_FSEEKO): Check that fseeko
2682 can be assigned to a function pointer. Problem reported by
2683 Peter Palfrader in <http://bugs.debian.org/401377>. Based on
2684 part of a patch by Ralf Wildenhues in that same bug report.
2686 2006-12-01 Paul Eggert <eggert@cs.ucla.edu>
2688 * tests/mktests.sh (ac_exclude_list): Exclude AC_FUNC_SETVBUF_REVERSED.
2689 * tests/semantics.at (AC_FUNC_SETVBUF_REVERSED): New test.
2691 2006-12-01 Eric Blake <ebb9@byu.net>
2693 * lib/autoconf/c.m4 (AC_LANG_INT_SAVE): Avoid newline, to aid in
2694 cross-compiling from cygwin to mingw.
2695 Reported by Bob Rossi. This resurrects the 2000-11-30 patch to
2696 aclang.m4, which was mistakenly removed in the 2001-09-17 patch
2697 to lib/autoconf/c.m4.
2699 2006-12-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2701 * lib/m4sugar/m4sh.m4 (_AS_ECHO_PREPARE): Use a longer test
2702 string for more reliable failure. Wrap the entire test that
2703 causes the broken Solaris printf to dump core, in a subshell,
2704 so the segmentation fault message is reliably suppressed.
2705 Fix shell expansion errors by using /usr/ucb/echo always;
2706 avoid an error on systems without it by another subshell.
2707 Avoid m4 expansion of `$1'. Set the zeroth argument of the
2708 subshell-$as_echo to `as_echo', for better error message.
2710 2006-11-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2712 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): If `BASH_ARGV' or
2713 `BASH_SOURCE' contain a newline, set them to empty, as they may
2716 2006-11-27 Paul Eggert <eggert@cs.ucla.edu>
2718 Turn AC_FUNC_SETVBUF_REVERSED into a noop. It's been obsolete for
2719 years and is too hard to maintain now. The last straw was
2720 reported by Jerker Baeck in
2721 <http://lists.gnu.org/archive/html/autoconf/2006-11/msg00102.html>.
2722 * NEWS: AC_FUNC_SETVBUF_REVERSED is now obsolete.
2723 * doc/autoconf.texi (Particular Functions): Move
2724 AC_FUNC_SETVBUF_REVERSED from here...
2725 (Obsolete Macros): ... to here. Say that it does nothing now.
2726 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
2727 Turn into (almost) a no-op.
2729 * lib/autoconf/c.m4 (AC_PROG_GCC_TRADITIONAL, AC_C_CONST):
2731 Do not recommend via AN_FUNCTION, AN_IDENTIFIER, or AN_HEADER.
2732 These macros are obsolescent and new applications shouldn't need them.
2733 * lib/autoconf/functions.m4 (AC_FUNC_CLOSEDIR_VOID, AC_REPLACE_FNMATCH):
2734 (AC_FUNC_GETLOADAVG, AC_FUNC_GETPGRP, AC_FUNC_MEMCMP):

2736 (AC_FUNC_STRFTIME, AC_FUNC_SETVBUF_REVERSED, AC_FUNC_UTIME_NULL):
2737 (AC_FUNC_VPRINTF): Likewise.
2738 * lib/autoconf/headers.m4 (AC_HEADER_DIRENT, AC_HEADER_STAT):
2739 (AC_HEADER_STDC, AC_HEADER_SYS_WAIT, AC_HEADER_TIME): Likewise.
2740 * lib/autoconf/types.m4 (AC_STRUCT_TM): Likewise.
2742 * doc/autoconf.texi (Setting Output Variables): Mention that
2743 @VAR1@VAR2 has unspecified behavior. Problem reported by
2745 * NEWS: Mention this.
2747 * Makefile.am: Put only a single '#' into the copyright notice,
2748 so that it's also present in the output file. Standardize wording
2749 in makefile copyright notices to match GNU coding standards.
2750 * bin/Makefile.am: Likewise.

2759 * tests/Makefile.am: Likewise.
2760 * lib/emacs/Makefile.am: Remove copyright notice; it's just a
2763 2006-11-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2765 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Fix error
2766 in the sed script that mangles the awk script: delete up to the
2767 first exclamation mark only.
2768 * tests/torture.at (Substitute and define special characters):
2771 2006-11-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2773 Rewrite config files generation: avoid quadratic growth in
2774 the number of substituted variables by using awk instead of sed
2775 for the bulk of the substitutions.
2776 * NEWS: Mention this.
2777 * doc/autoconf.texi (Setting Output Variables): `|#_!!_#|' is also
2778 forbidden in the output (and thus input) file.
2779 * lib/autoconf/status.m4 (_AC_AWK_LITERAL_LIMIT): New macro.
2780 (_AC_OUTPUT_FILES_PREPARE): Instead of several sed scripts,
2781 generate just one large awk script for substitutions,
2782 eliminating much of the earlier complexity, while adding some
2783 new complexity. Only expand the substitution templates at
2784 configure time, for smaller configure script size. If
2785 _AC_SUBST_FILES are used, test 'awk' for working getline support
2786 at config.status time. If absent, interpolate through the
2787 shell. The awk script was written with much help
2788 from Paolo Bonzini and Paul Eggert.
2789 (_AC_SED_CMD_NUM, _AC_SED_DELIM_NUM, _AC_SED_FRAG): Removed.
2790 (_AC_SED_FRAG_NUM): Likewise.
2791 (_AC_SUBST_CMDS): Renamed from...
2792 (_AC_SED_CMDS): ...this.
2793 (_AC_OUTPUT_FILE): Use _AC_SUBST_CMDS.
2794 * tests/torture.at (Substitute a 2000-byte string): Also
2795 substitute a line with 1000 words, and a variable with several
2797 (Substitute and define special characters): Test awk special
2798 characters, and put substitution input strings `@foo@' in the
2799 output, to test that no recursion happens; test several other
2800 combinations from Paolo Bonzini.
2802 2006-11-25 Paul Eggert <eggert@cs.ucla.edu>
2804 * lib/autotest/general.m4 (AT_INIT): Undo recent changes
2805 that replaced echo with AS_ECHO where this wasn't necessary.
2806 Problem reportd by Ralf Wildenhues.
2807 * lib/m4sugar/m4sh.m4 (_AS_ECHO_PREPARE): Port to Solaris 7,
2808 where "/usr/bin/printf '%s\n' S" dumps core if S is long.
2809 This is Sun bug 4206210. Problem reportd by Ralf Wildenhues.
2811 2006-11-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2813 * lib/freeze.mk (GREP): Removed, no need to initialize this.
2815 2006-11-21 Paul Eggert <eggert@cs.ucla.edu>
2817 * doc/autoconf.texi (Limitations of Usual Tools): Don't claim
2818 that traditional Awk lacks 3-arg "split". It has it.
2819 Mention that FS must be a single character, and a few other
2820 99-byte limits of traditional Awk.
2821 Mention that if (i in a) doesn't work with traditional Awk.
2823 2006-11-18 Paul Eggert <eggert@cs.ucla.edu>
2825 * tests/autotest.at (BSx641-newline in command):
2826 (BS-BS-newline in command, BSx640-newline in command):
2827 (Newline-CODE-BS-newline in command):
2828 (Single-quote-BS-newline in command):
2829 (Single-quote-newline-BS-newline in command):
2830 Use printf '%s\n' instead of echo, for portability to hosts
2831 where echo interprets backslashes. This will break on hosts
2832 that lack printf, but for now let's assume all such hosts
2833 are dead (if not, we should get reports of test failures).
2835 2006-11-17 Paul Eggert <eggert@cs.ucla.edu>
2837 'echo' has some portability problems, when given a first argument
2838 with a leading '-', or when given any argument containing '\'.
2839 Avoid using 'echo' in these cases.
2840 * bin/Makefile.am $(bin_SCRIPTS): Rewrite to avoid 'echo' entirely.
2841 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX, AC_PROG_OBJC): Likewise.
2842 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
2843 * lib/autotest/general.m4 (AT_INIT): Likewise.
2844 * bin/autoconf.as: Use AS_ECHO rather than plain echo, when the
2845 argument might be unportable.

2864 (AS_TR_SH, AS_TR_CPP, AS_VAR_GET): Likewise.
2865 * bin/autoconf.as: Redo verbose flag implementation, as the old
2866 scheme wouldn't work with AS_ECHO.
2867 * lib/autotest/general.m4 (AT_INIT): Likewise.
2868 * lib/autoconf/general.m4 (AC_MSG_RESULT, AC_MSG_RESULT_UNQUOTED):
2869 Don't use ECHO_T, since ECHO_N is now reliable.
2870 * lib/autotest/general.m4 (AT_INIT): Likewise.
2871 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Use sed "$script"
2872 rather than using a here-document to put the script into a file.
2873 (_AC_DO_ECHO): Hoist the eval out of the echo, so that we can
2875 * lib/m4sugar/m4sh.m4 (AS_VAR_GET): Likewise.
2876 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Use
2877 AS_ECHO_N rather than ECHO_N and ECHO_C. This doesn't fix any
2878 bug, but we might as well stop using ECHO_N and ECHO_C internally.
2879 * lib/autotest/general.m4 (AT_SETUP): Likewise.

2881 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
2882 (_AC_OUTPUT_MAIN_LOOP): Rework echo so that it has just one
2883 operand, as AS_ECHO requires. Avoid double file name expansion.
2884 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Invoke _AS_ECHO_PREPARE.
2885 Don't set as_nl, since _AS_ECHO_PREPARE does that now.
2886 (_AS_PREPARE): Comment that _AS_ECHO_N_PREPARE is just for user code.
2887 (AS_ECHO, AS_ECHO_N, _AS_ECHO_PREPARE): New macros.
2888 * tests/c.at (AC_PROG_CPP without warnings, AC_PROG_CPP via CC):
2889 Double-quote strings that would otherwise contain M4 comments.
2890 * tests/m4sh.at (AS_ECHO and AS_ECHO_N): New test.
2892 * configure.ac (AC_INIT): Bump to 2.61a.
2895 2006-11-17 Paul Eggert <eggert@cs.ucla.edu>
2899 * configure.ac (AC_INIT): Bump to 2.61.
2902 * tests/autotest.at (Macro with backslash in a test title):
2903 Comment out for now, as this tests neither fails nor passes
2904 reliably. Problem reported by Ralf Wildenhues.
2906 2006-11-16 Paul Eggert <eggert@cs.ucla.edu>
2908 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE): Fix some typos
2909 in previous change, which caused test failures.
2911 2006-11-16 Stepan Kasal <kasal@ucw.cz>
2913 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Factor out
2914 code for --enable, --disable, --with, and --without to...
2915 (_AC_INIT_PARSE_ENABLE): ... a new macro.
2916 * doc/autoconf.texi (Package Options):

2991 and non-portable sed scripts, and use $CONFIG_SHELL when invoking
2994 2006-11-08 Paul Eggert <eggert@cs.ucla.edu>
2996 * lib/autoconf/types.m4 (AC_TYPE_LONG_LONG_INT): Set
2997 ac_cv_type_long_long_int to 'yes' instead of 'cross-compiling'.

3029 Single-quote in a test title,
3030 Double-quote in a test title): Don't expect failure anymore.
3031 (Backslash in a test title): Put a non-whitespace character after the
3032 backslash so that Bourne shells might actually see it as an escape
3034 (Brackets in a test title,

3036 Comma in a test title,
3037 Quoted Macro in a test title,

3041 Macro with double-quote in a test title,
3042 Macro with backslash in a test title): New tests expected to fail.
3043 * tests/torture.at (#define header templates): M4-quote this title in
3044 AT_SETUP call so that no M4 code is commented inadvertently somewhere.
3045 The visible effect was a stray [] in the testsuite output.
3047 2006-10-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3049 * doc/autoconf.texi (Limitations of Builtins): Do not invoke
3050 `trap ... 0' inside a function, for AIX sh.
3052 2006-10-26 Paul Eggert <eggert@cs.ucla.edu>
3054 * tests/base.at (AC_COMPUTE_INT): Test **0** rather than 1 / 0,
3055 since powerpc-apple-darwin8-gcc-4.0.1 (Apple Computer, Inc. build
3056 5363) simply issues a warning when dividing by zero at compile
3057 time. Problem reported by Elias Pipping.
3059 2006-10-26 Eric Blake <ebb9@byu.net>
3062 * doc/autoconf.texi (Evaluation Macros): Improve the example to
3063 show effect on macros that expand with commas.

3091 If FUNCTION-BODY is nonempty, use AC_LINK_IFELSE rather than
3092 AC_COMPILE_IFELSE, to work around problem with OSF/1 4.0F fseeko
3093 reported by Nelson H. F. Beebe for Coreutils 6.4.
3095 * tests/tools.at (autoconf --trace: user macros): Remove test
3096 for tracing multiline macros, since m4 1.4.7a uses a different

3128 * tests/base.at (AC_COMPUTE_INT): Test this, not AC_CACHE_CHECK_INT.

3173 2006-10-14 Paul Eggert <eggert@cs.ucla.edu>
3175 (Imported from Automake.)
3176 * build-aux/install-sh (posix_mkdir): Reject FreeBSD 6.1 mkdir -p -m,
3177 which incorrectly sets the mode of an existing destination
3178 directory. In some cases the unpatched install-sh could do the
3179 equivalent of "chmod 777 /" or "chmod 0 /" on a buggy FreeBSD
3180 system. We hope this is rare in practice, but it's clearly worth
3181 fixing. Problem reported by Alex Unleashed in
3182 <http://lists.gnu.org/archive/html/bug-autoconf/2006-10/msg00012.html>.
3183 Also, don't bother to check for -m bugs unless we're using -m;
3184 suggested by Stepan Kasal.

3230 2006-10-13 Stepan Kasal <kasal@ucw.cz>
3232 * doc/autoconf.texi (Autoheader Macros): Warn that the text
3233 added to the template can get mangled.
3235 2006-10-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3237 * lib/autoconf/functions.m4 (AC_FUNC_OBSTACK): In the test,
3238 include the default headers, and redefine obstack_chunk_alloc
3239 and obstack_chunk_free. Fixes false failure with glibc.
3241 2006-10-12 Paul Eggert <eggert@cs.ucla.edu>
3243 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Set as_executable_p,

3258 * lib/autoconf/specific.m4 (AC_USE_SYSTEM_EXTENSIONS): Likewise.
3260 * lib/m4sugar/m4sh.m4 (AS_TEST_X): New macro.
3261 (AS_EXECUTABLE_P): Use as_test_x rather than as_executable_p.
3262 (_AS_TEST_PREPARE): Set as_test_x rather than as_executable_p.
3263 Use a better substitute, by inspecting the output of "ls"
3264 rather than just using ":".
3265 * lib/autoconf/general.m4 (_AC_LINK_IFELSE): Use AS_TEST_X
3266 rather than AS_EXECUTABLE_P, since we needn't worry about
3267 non-regular files here.
3269 * NEWS: Autoconf-generated shell scripts no longer export BIN_SH,
3270 due to configuration hassles with this. See Tonya Underwood's report
3271 <http://lists.gnu.org/archive/html/bug-autoconf/2006-10/msg00003.html>.

3282 * lib/m4sugar/m4sh.m4 (AS_BOURNE_COMPATIBLE): Move the
3283 initialization which is not inherited through the environment
3284 (_AS_BOURNE_COMPATIBLE): ... to this new macro.
3285 (_AS_RUN): Call _AS_BOURNE_COMPATIBLE, not AS_BOURNE_COMPATIBLE.

3290 problems with mkdir -p -m.
3292 2006-10-06 Paul Eggert <eggert@cs.ucla.edu>
3294 * lib/autoconf/c.m4 (_AC_PROG_PREPROC_WORKS_IFELSE): Remove
3295 comment about ac_cpp_err; it was incorrect, and anyway
3296 ac_cpp_err is being removed below.
3297 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE): Don't
3298 set ac_cpp_err to 'yesyes' if preproc_warn_flag and werror_flag
3299 are both 'yes'. In fact, don't bother setting ac_cpp_err at all;
3301 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't log our funky tests
3302 with werror_flag and conftest.err and so forth. This is more
3303 compatible with how _AC_PROG_PREPROC_WORKS_IFELSE behaves,
3304 and anyway the user shouldn't normally want to see this gorp logged.
3305 Problem reported by Ralf Wildenhues.
3306 * lib/autoconf/lang.m4 (AC_LANG_WERROR): werror_flag's default is
3307 empty, not 'no', since the rest of the code uses 'test -z'.
3309 2006-10-04 Paul Eggert <eggert@cs.ucla.edu>
3311 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE):
3312 Use a single call to AC_DO_TOKENS rather than multiple, for
3314 (_AC_LINK_IFELSE): Test that resulting file is executable.
3315 Problem reported by mwoehlke in
3316 <http://lists.gnu.org/archive/html/bug-coreutils/2006-10/msg00048.html>.
3318 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Use "test -x /" rather
3319 than creating a file to use with test -x; this is much faster.
3321 2006-10-02 Bruno Haible <bruno@clisp.org>
3323 * lib/autom4te.in (Automake-preselections): Add
3324 AM_GNU_GETTEXT_INTL_SUBDIR, for automake 1.10.
3326 2006-09-27 Stepan Kasal <kasal@ucw.cz>
3328 * doc/autoconf.texi (Writing testsuite.at): Fix a typo: for
3329 standard error, `experr' should be used, not `expout'.
3331 2006-09-26 Paul Eggert <eggert@cs.ucla.edu>
3333 * lib/autoconf/functions.m4 (AC_FUNC_FSEEKO): Don't compile the

3335 * lib/autoconf/specific.m4 (_AC_SYS_LARGEFILE_MACRO_VALUE):
3336 Set cache var to 'unknown' (not 'no') if leaving the macro unset
3337 still doesn't let the program compile.
3338 (AC_SYS_LARGEFILE): Test for _LARGE_FILES only if earlier tests
3341 * lib/autoconf/functions.m4: Fix problems reported by Ralf Wildenhues.
3342 (AC_FUNC_ERROR_AT_LINE): Don't bother to check for error.h. Just
3343 include it, without including anything else.
3344 (AC_FUNC_FSEEKO): Avoid gcc -Wall warnings about constant
3346 (AC_FUNC_STRNLEN): Require AC_USE_SYSTEM_EXTENSIONS.

3351 `error.h', and include it, for a `error_at_line' prototype.
3352 Use a nonempty format string in the link test.
3353 * lib/autoconf/functions.m4 (AC_FUNC_WAIT3): Include <sys/wait.h>,

3363 values. Problem reported by Ralf Wildenhues.

3525 except the first two arguments are reversed.
3526 * doc/autoconf.texi (Caching Results): New macro AC_CACHE_CHECK_INT.

3574 * lib/autoconf/programs.m4 (AC_PROG_LEX): Let _AC_PROG_LEX_YYTEXT_DECL
3576 (_AC_PROG_LEX_YYTEXT_DECL): Handle caching correctly; the old code
3577 didn't work if some values were cached but not others. Test for
3578 broken lex libraries like native ia64-hp-hpux11.22; see
3579 <http://sources.redhat.com/ml/binutils/2003-12/msg00337.html>, and
3580 work around the problem by preferring an empty LEXLIB to -lfl or
3581 -ll. Let the user set LEXLIB='' to indicate no library needed.

3708 rather than "#if HAVE_STDLIB_H", so that it now works with "gcc
3709 -Wundef -Werror". Problem reported by David Fang in

3733 problems with arg script text that doesn't end in newline, and

3736 2006-08-12 Alexandre Julliard <julliard@winehq.org> (tiny change)
3738 * lib/autoconf/libs.m4 (AC_PATH_X_DIRECT): Replace another

3770 less skeptical about "volatile", after discussion with
3771 Bruno Haible on bug-gnulib.

3811 * tests/torture.at (Configuring subdirectories): Set CONFIG_SITE
3812 more globally, since the 2006-06-30 patch didn't suffice. Problem
3813 reported by Keith Marshall. Also, don't bother with builddir2,
3814 since it shouldn't be needed any more.
3816 2006-07-07 Paolo Bonzini <bonzini@gnu.org>

3835 2006-07-02 Paul Eggert <eggert@cs.ucla.edu>
3837 * lib/autoconf/types.m4 (AC_TYPE_LONG_LONG_INT):
3838 Require that long long int be at least 64 bits wide. C99 requires
3839 this and enough programs depend on it so we should check for it.
3840 Bruno Haible reports in
3841 <http://lists.gnu.org/archive/html/bug-gnulib/2006-06/msg00286.html>
3842 that long long int is 32 bits wide with some nonstandard compilers.

3853 2006-06-28 Paul Eggert <eggert@cs.ucla.edu>
3855 * doc/autoconf.texi: Be more consistent about using @acronym with
3856 "HP" and "HP-UX". Remove mention of OSF; the old version wasn't
3857 quite right (it talked about "OSF/Tru64", even though the
3858 operating systems were called OSF/1, Digital UNIX, and Tru64 UNIX,
3859 and it even mentioned "OSF 4"!) and at this point there's little
3860 reason to talk about OSF any more, since it died in 1994.
3861 (Specific Compiler Characteristics): Simplify example of
3862 negative-size array.
3863 (File Descriptors): Reorder to make the text flow better.
3864 Remove joke about "appreciate the various levels"; I didn't get it.

3866 <http://lists.gnu.org/archive/html/bug-coreutils/2006-06/msg00225.html>.
3867 (File Descriptors, Limitations of Usual Tools):
3868 Tone down the advice against renaming or removing open files.
3869 (Limitations of Usual Tools): Add a new section, on 'rm'.
3871 2006-06-26 Stepan Kasal <kasal@ucw.cz>
3873 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Use -lX11, not
3874 -lXt in LIBS, idea from Karsten Hopp; this was due since
3877 2005-09-18 Paul Eggert <eggert@cs.ucla.edu>
3878 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Look for X11/Xlib.h
3879 and XrmInitialize rather than X11/Intrinsic.h and XtMalloc
3880 (which belong to Xt, not X itself). See Debian bug 327655.

3903 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Expand tests for
3904 datarootdir-related errors only if AC_DATAROOTDIR_CHECKED is
3906 * doc/autoconf.texi (Changed Directory Variables): New node,
3907 to document the whole `datarootdir' business a bit better.
3909 * tests/torture.at (datarootdir workaround): Extend test.
3910 Prompted by report by Alexandre Julliard.
3912 2006-06-22 Paul Eggert <eggert@cs.ucla.edu>
3914 * lib/autoconf/c.m4 (_AC_PROG_CC_C89): Check for C89 incompatibility
3915 when using default mode of IBM C 6 for AIX. Problem and two-line
3916 fix reported by Larry Jones.
3918 2006-06-22 Alexandre Julliard <julliard@winehq.org>
3920 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Avoid warning
3921 about literal '${datarootdir}' if a definition is found in the
3924 2006-06-20 Paul Eggert <eggert@cs.ucla.edu>
3926 * NEWS: Use "M4" rather than "m4" when appropriate.
3927 Problem reported by Eric Blake.
3928 * doc/autoconf.texi: Likewise.
3929 Use @acronym around BSD, GCC, and GNU when appropriate.
3930 (Why GNU M4): Renamed from "Why GNU m4".
3931 (Redefined M4 Macros): Mention that Posix
3932 m4wrap takes only 1 argument, but GNU M4 1.4.x takes more.
3933 (Buffer Overruns): Mention size_t and ptrdiff_t as alternatives
3936 2006-06-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3938 * bin/autom4te.in (handle_output): Do not forbid the empty
3940 * tests/tools.at (autoconf: the empty token): New test.
3942 2006-06-20 Stepan Kasal <kasal@ucw.cz>
3944 * lib/m4sugar/m4sugar.m4 (m4_init): Merge the two m4_wrap
3945 calls, so that we do not care whether they are LIFO or FIFO;
3946 in the m4_wrap, do not check which diversion is the topmost
3947 one, just check that the stack is balanced at the end.
3948 * lib/m4sugar/m4sh.m4 (AS_INIT): We are going to change the
3949 base diversion forever--pop the previous diversion before
3950 opening the new one; consequently, remove the m4_wrap call.
3951 * lib/autotest/general.m4 (AT_INIT): Likewise.
3952 * tests/m4sugar.at: Do not use
3953 m4_wrap([m4_diversion_pop([..])]), for educational purposes.
3955 2006-06-19 Paul Eggert <eggert@cs.ucla.edu>
3956 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3958 * NEWS: Document that m4wrap/m4_wrap might not be LIFO.
3959 * doc/autoconf.texi (Redefined M4 Macros): Likewise.
3960 Rework example of m4wrap token-pasting trouble so that it doesn't
3961 care whether it's LIFO or FIFO.
3962 Fix some "contrary to"s that are awkward in English.
3964 2006-06-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3966 * lib/autoconf/types.m4 (_AC_TYPE_INT): Set `$ac_cv_c_int$1_t'
3967 to `yes' instead of `int$1_t' if the type is found, for more
3968 consistent configure output (where $1 is the number of bits).
3969 (_AC_TYPE_UINT): Likewise for `uint$1_t'.
3970 Suggested by Bruno Haible.
3972 * lib/autoconf/types.m4 (_AC_TYPE_UNSIGNED_INT): Solaris 2.5.1
3973 needs _UINT8_T and _UINT64_T defines as well, to avoid clashes
3974 with system headers. Report by Bruno Haible.
3976 2006-06-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3978 * config/config.guess, config/config.sub: Sync from upstream.
3980 * bin/Makefile.am (autoconf.in): Use `--melt' for autom4te,
3981 in order to avoid picking up an older installed frozen m4sh.m4f.
3982 Besides an outdated shell startup, this could have been created
3983 by an earlier M4 version with incompatible frozen file format.
3985 2006-06-16 Paul Eggert <eggert@cs.ucla.edu>
3987 * README: Recommend m4 1.4.4 instead of 1.4.3..
3988 * doc/autoconf.texi: Likewise.
3989 (Special Chars in Names): Say that $(.FOO) is portable, as
3990 suggested by Stepan Kasal.
3991 (Installation Directory Variables, Build Directories):
3992 (Automatic Remaking, Subdirectories, Fortran Compiler):
3993 (Making testsuite Scripts, Defining Directories):
3994 Quote variable usages better.
3995 (Making testsuite Scripts): Add clean-local rule to makefile
3996 snippet, by Eric Blake.
3997 (Installation Directory Variables): Fix table item font.
3998 Reword slightly to clarify. Generalize advice about
3999 not using special characters to include all file-related
4000 vars, not just VPATH.
4001 (Special Chars in Variables): Warn about special characters in
4003 (Assignments): Clarify default-value example as suggested by
4005 <http://lists.gnu.org/archive/html/autoconf-patches/2006-06/msg00072.html>.
4006 (Special Shell Variables): Note leading ./ or ../, as suggested
4008 (Limitations of Builtins): Under cd, warn about CDPATH.
4009 (The Make Macro MAKEFLAGS): Untabify. Problem reported by
4012 2006-06-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4014 * doc/autoconf.texi (Configuration Actions): Remove duplicate
4015 `@var', for texi2html.
4016 (Systemology): Some more word wrapping, for DVI output.
4017 (autom4te Invocation): The short option for `--melt' is `-M',
4020 2006-06-15 Paul Eggert <eggert@cs.ucla.edu>
4022 * doc/autoconf.texi: More formatting and English tweaks,
4023 many suggested by Ralf Wildenhues.
4024 Reword to avoid "@code{...}'s" and the like, since it's ugly
4025 with Emacs info mode. discontents -> woes.
4026 Put a few "will"s back. time stamp -> timestamp.
4027 side-effect -> side effect.
4029 2006-06-14 Paul Eggert <eggert@cs.ucla.edu>
4031 * doc/autoconf.texi (Initializing configure, Shell Substitutions):
4032 Warn about $@ not persisting. Problem reported by Julien Danjou in
4033 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=372179>.
4034 (Special Chars in Names): Renamed from Leading _ in Macro Names.
4035 Mention other special chars, too.
4037 2006-06-14 Eric Blake <ebb9@byu.net>
4039 * doc/autoconf.texi (The Make Macro MAKEFLAGS): New node.
4041 2006-06-13 Paul Eggert <eggert@cs.ucla.edu>
4043 * doc/autoconf.texi: Some systematic minor improvements, as
4044 follows. Use "makefile" when talking about makefiles
4045 generally (which might be named "makefile" or "Makefile" or even
4046 "foo.mk"), "Makefile" when talking about a specific makefile
4047 called "Makefile". This unclutters the text from weird quotes
4048 (e.g., "`Makefile's" in info mode). Similarly, use "@var{foo}
4049 values" rather than "@var{foo}s" and similar constructs containing
4050 "}s". Use "Make rules" rather than "Makefile rules". Minor
4051 English-language improvements. Change the prefix "sub-" to "sub"
4053 Put blank lines around examples more consistently.
4054 Avoid "rather" and "very" as intensifiers.
4055 Avoid "will" as an auxiliary.
4056 (Limitations of Make): Split this node into....
4057 (Portable Make, $< in Ordinary Make Rules, Failure in Make Rules):
4058 (Leading _ in Macro Names, Backslash-Newline-Newline):
4059 (Backslash-Newline Comments, Long Lines in Makefiles):
4060 (Macros and Submakes, The Make Macro SHELL, Comments in Make Rules):
4061 (obj/ and Make, make -k Status, VPATH and Make):
4062 (VPATH and Double-colon, $< in Explicit Rules):
4063 (Automatic Rule Rewriting, OSF/Tru64 Directory Magic):
4064 (Make Target Lookup, Single Suffix Rules, Timestamps and Make):
4065 New nodes, resulting from splitup of Limitations of Make.
4066 All cross-references changed. Raise the top node from
4067 a section to a chapter, and all subnodes accordingly.
4068 Redo the introductory wording to match the new organization.
4069 (Installation Directory Variables): Use an example that is
4070 closer to what Autoconf actually does. Mention that VPATH's
4071 value should not contain metacharacters or white space.
4072 (Fortran Compiler): Fix a VPATH bug in an example.
4073 (Leading _ in Macro Names): Mention that this problem is no longer
4074 of practical concern.
4075 (VPATH and Make): Reword the advice to make it clearer
4076 that Autoconf and Automake support VPATH in non-GNU make, but
4077 many packages have bugs in this area.
4078 ($< in Explicit Rules): Refer to Build Directories rather
4079 than using a (non-VPATH-safe) example.
4080 (Automatic Rule Rewriting): Mention the sort of disaster that
4081 can ensue with Solaris-style rule rewriting with VPATH.
4083 2006-06-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4085 * doc/install.texi (Compilers and Options): Weaken the
4086 suggestion to use GNU make for VPATH builds.
4088 * lib/autom4te.in (Automake-preselections): Add AM_PROG_CXX_C_O,
4089 AM_PROG_F77_C_O, AM_PROG_FC_C_O, AC_FC_SRCEXT, AC_FC_FREEFORM.
4091 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Fix M4 quotation
4092 in regular expression.
4094 2006-06-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4096 * doc/autoconf.texi (Installation Directory Variables):
4097 Drop extra @samp from `@table @samp' item.
4098 (Limitations of Usual Tools): Comment fix.
4099 Do not nest @samp just to point to other table items.
4100 (Writing testsuite.at) <AT_CHECK>: The second argument to
4101 `@dvar' is already @samp'ed.
4102 (Making testsuite Scripts) <AC_CONFIG_TESTDIR>: Likewise,
4103 do not use @var in the second argument.
4105 2006-06-07 Paul Eggert <eggert@cs.ucla.edu>
4107 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Look for
4108 $as_shell.exe too. Problem reported by Andreas Buening in
4109 <http://lists.gnu.org/archive/html/autoconf/2006-06/msg00038.html>.
4111 2006-06-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4113 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA): Work around
4114 `unused variable' compiler warning, for `-Wall -Werror'.
4115 Reported by Jaap Haitsma in
4116 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00012.html>.
4118 2006-06-06 Paul Eggert <eggert@cs.ucla.edu>
4120 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Remove core file, in
4121 case the compiler dumps core. Problem reported for
4122 OpenServer 5.0.7 by Tim Rice in
4123 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00019.html>.

4127 2006-06-06 Tim Rice <tim@multitalents.net>.
4129 * lib/freeze.mk: Quiet check-forbidden-patterns so the string
4130 "ERROR" only shows up in "make check" output if there is an

4139 * NEWS: Don't blame non-GNU VPATH compatibility issues on Automake.
4141 * doc/autoconf.texi (Integer Overflow): Mention that INT_MIN % -1
4142 typically overflows on x86 CPUs, even though the C standard

4154 * config/texinfo.tex: Sync from upstream.
4156 * bin/autoreconf.in: Trace `LT_CONFIG_LTDL_DIR'; if it has been
4157 seen, invoke libtoolize with `--ltdl' argument.
4158 * lib/autom4te.in (Autoreconf-preselections): Adjust.
4160 Suggested by Eric Blake.
4162 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
4164 * NEWS: Whoops! AC_FUNC_STRNLEN isn't obsolescent. Problem
4165 reported by Ralf Wildenhues.

4181 * tests/base.at: Check AC_REQUIRE's error message.
4182 * tests/local.at (AT_CHECK_M4): New macro, almost identical
4184 (AT_CHECK_AUTOM4TE): ... which is now a thin wrapper around
4186 (AT_CHECK_AUTOCONF): Use AT_CHECK_M4; no longer support
4187 `expout' as the last parameter.
4188 * tests/tools.at: Adapt to the above change.
4190 2006-06-04 Stepan Kasal <kasal@ucw.cz>
4192 * doc/autoconf.texi (Limitations of Usual Tools): Correct
4193 information about race-free implementations of mkdir.

4202 2006-06-04 Paul Eggert <eggert@cs.ucla.edu>
4204 * NEWS: GNU make now recommended for VPATH builds.
4205 Mention that some macros are now documented to be obsolescent.
4206 * doc/autoconf.texi:
4207 Prefer "current" to "modern" to describe
4208 currently-used (albeit perhaps old-fashioned) hosts.
4209 Mention which ancient features no longer need to be worried about.
4210 setgid -> set-group-ID
4211 setuid -> set-user-ID (these are the Posix terms)
4212 Fix some misuses of "only".
4213 (AC_C_BACKSLASH_A, AC_C_CONST, AC_C_PROTOTYPES):
4214 (AC_C_STRINGIZE, AC_C_VOLATILE, AC_FUNC_CLOSEDIR_VOID):

4227 Omit longwinded and obsolescent discussion of cp -f.
4228 Modernize discussion of expr, ls.
4229 (Limitations of Make): Modernize discussion of VPATH builds.
4230 Mention $? as a workaround in some cases.
4231 * doc/install.texi (Basic Installation):
4232 Mention "./configure; make; make install" first. Be more
4233 specific about why this file is generic. Remove unnecessary
4234 parens. Remove misleading "only". Remove obsolete advice
4235 about csh. Don't say "configure" takes awhile; say it
4236 might take a while. Suggest CFLAGS=-g rather than CFLAGS=-O2,
4237 and CC=c99 rather than CC=c89, as these are blessed by current
4238 Posix. Recommend GNU make if doing a VPATH build.
4240 2006-06-03 Paul Eggert <eggert@cs.ucla.edu>
4242 * doc/autoconf.texi: Use a consistent style "$ @kbd{...}" for
4243 examples involving shell prompts.

4246 and Paul Eggert <eggert@cs.ucla.edu>
4248 * doc/autoconf.texi (Here-Documents): Add details about the
4249 pre-ksh93g bug. Reword slightly to make it clearer. Consistently
4250 use "here-documents" instead of "here documents".

4282 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
4284 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be more conservative
4285 about quoting ac_try: quote all of it, if any of it seems suspicious.
4286 This means we don't have to worry about ${ or sed any more.
4287 Also, double-quote the case statement, to work around misuses via
4288 underquoting as reported by Ralf Wildenhues in
4289 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00169.html>.
4290 (_AC_EVAL_STDERR): Revert, since evidently some packages rely on this
4291 undocumented and dangerous macro.
4292 Problem reported by Ralf Wildenhues in

4303 * lib/autoconf/general.m4: Revert AC_TRY_EVAL and AC_TRY_COMMAND,
4304 since evidently some packages rely on the old, broken behavior.
4305 Problem reported by Ralf Wildenhues in
4306 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00160.html>.
4307 (AC_TRY_EVAL, AC_TRY_COMMAND, _AC_EVAL): Go back to the
4308 pre-2006-05-26 definitions, but leave in the comments that
4309 these macros are dangerous and should not be used.
4310 (_AC_DO_ECHO): Renamed from _AC_EVAL_ECHO. All callers changed.
4311 (_AC_DO): Renamed from _AC_EVAL. All callers changed.
4312 (_AC_DO_STDERR): Renamed from _AC_EVAL_STDERR. All callers changed.
4313 (_AC_DO_VAR): Renamed from AC_TRY_EVAL.
4314 (_AC_DO_TOKENS): Renamed from AC_TRY_COMMAND.
4316 2006-05-29 Paul Eggert <eggert@cs.ucla.edu>
4318 * lib/autoconf/status.m4 (AC_OUTPUT_MAKE_DEFS): Rewrite to avoid
4319 the use of 'tr', since this is our only use of 'tr'.
4321 2006-05-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4322 and Paul Eggert <eggert@cs.ucla.edu>
4324 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE):
4325 Don't assume 'grep' works on long lines, since AIX grep doesn't.
4327 2005-05-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4329 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Do not use `grep' on
4330 the output file in the `${datarootdir}' test.
4332 2005-05-28 Stepan Kasal <kasal@ucw.cz>
4333 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4335 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If we have not seen
4336 mention of `datarootdir' in the input file(s), but literal
4337 `${datarootdir}' in the output file, and we haven't warned yet,
4338 then warn as well: the user may have (erroneously) used
4339 `AC_SUBST([mydatadir], [$datadir/my])' instead of the correct
4340 `AC_SUBST([mydatadir], ['${datadir}/my'])'.
4341 * tests/torture.at (datarootdir workaround): Extend this test.
4344 2006-05-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4345 and Paul Eggert <eggert@cs.ucla.edu>
4347 * doc/autoconf.texi (autoheader Invocation): The first argument to
4348 `AC_DEFINE_UNQUOTED' need not be a literal. Mention the
4349 alternatives and clear up the language a bit.
4351 2006-05-27 Paul Eggert <eggert@cs.ucla.edu>
4353 * NEWS: Reword notice for AC_TRY_COMMAND, AC_TRY_EVAL,
4354 ac_config_guess, ac_config_sub, ac_configure.
4355 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
4356 Fix typo that prevented an unnecessary space from being removed.

4362 * doc/autoconf.texi (Particular Programs, Limitations of Usual Tools):
4363 Use better wording to talk about AC_PROG_MKDIR_P's thread-safety.
4364 Don't use the term "thread-safe" to talk about mkdir race
4365 conditions, since the problem is more a process than a thread
4366 issue. Problem reported by Stepan Kasal in:
4367 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00088.html
4368 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Use code that mimics
4369 the test for 'install' more closely. Look at MKDIR_P first.
4370 Look in the PATH, and at /opt/sfw/bin.
4371 Look for a 'gmkdir' program as well (Solaris 10 /opt/sfw/bin/gmkdir).
4372 Don't bother to try mkdir -p, since we already check mkdir --version;
4373 just look at the version number. (There's no easy way to check
4374 for race-free implementations.)
4375 * tests/tools.at (autoconf: subdirectories): Adjust to above
4376 changes, since MKDIR_P now might end in "/mkdir -p".
4378 * doc/autoconf.texi (autoheader Invocation): Mention that the
4379 first arg of AC_DEFINE_UNQUOTED must be a literal.
4380 Problem reported by Ben Pfaff in
4381 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00090.html>.
4383 * NEWS: Mention that AC_TRY_COMMAND and AC_TRY_EVAL may be removed.
4384 * doc/autoconf.texi (Special Chars in Variables): New section.
4385 (Preset Output Variables): Warn about special chars in CPPFLAGS.
4386 (Installation Directory Variables): Quote $(datadir) better.
4387 (Limitations of Builtins): Describe some of eval's trickiness.
4389 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Simplify quoting.
4390 * lib/autoconf/fortram.m4 (_AC_PROG_FC_V_OUTPUT): Likewise.
4391 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Put leading space
4392 in front of every arg, not just trailing args. Quote apostrophes.
4393 (_AC_EVAL_ECHO): New macro.
4394 (_AC_EVAL, AC_EVAL_STDERR): Use it. Quote arg of eval.
4395 (AC_TRY_EVAL, AC_TRY_COMMAND): Mention that these macros might get
4397 (_AC_LINK_IFELSE): Use proper rule for shell continuation lines,
4398 exposed by quoting of eval argument. Put the command on line line
4400 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): Use eval more safely.
4401 (_AC_PATH_X, AC_PATH_X): Quote more safely.
4402 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Use eval more safely.
4403 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Don't use eval.
4404 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Minor style change.
4405 Handle special chars in prefix, ac_srcdir, ac_aux_dir.
4406 Use eval more safely.
4407 (_AC_OUTPUT_CONFIG_STATUS): Adjust to above changes.
4408 * lib/m4sugar/m4sh.m4 (AS_VAR_GET): Note that this API needs
4410 * tests/base.at (AC_TRY_COMMAND): Use proper rule for shell continuation
4411 lines, exposed by quoting of eval argument.
4413 2006-05-26 Stepan Kasal <kasal@ucw.cz>
4414 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4416 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Drop the
4417 initialization of `ac_cv_exeext', do not override it if it was
4418 already set, unless it was set to `no', for compatibility with
4419 Autoconf-2.13, and comment this.
4420 Do not export `ac_cv_exeext', Libtool hasn't needed this for years.
4421 (_AC_COMPILER_EXEEXT_DEFAULT): Likewise, do not export it.
4422 (_AC_COMPILER_EXEEXT_WORKS, _AC_COMPILER_EXEEXT_CROSS): Typos.
4423 * doc/autoconf.texi (Compilers and Preprocessors) <EXEEXT>:
4424 Document that this test may be overridden by setting
4427 2006-05-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4429 Revert these two patches:
4431 2006-04-06 Eric Blake <ebb9@byu.net>
4432 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_O): Inside cache
4433 check, s/ac_exeext/ac_cv_exeext/. Fixes regression introduced
4436 2006-04-01 Stepan Kasal <kasal@ucw.cz>
4437 Clean up _AC_COMPILER_EXEEXT* macros.
4438 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't try to
4439 detect exeext, it will be done by _AC_COMPILER_EXEEXT_O; just set
4440 ac_file to the name of the default output file and call
4441 _AC_COMPILER_EXEEXT_WORKS. Move the definition of ac_files and the
4442 initial `rm' of the candidate files...
4443 (_AC_COMPILER_EXEEXT): ... here and simplify them. Moreover, use
4444 the same list in subsequent `rm' calls, and for the temporary
4445 redefinition of ac_clean_files; call _AC_COMPILER_OBJEXT at the end,
4446 and don't call the other _AC_COMPILER_EXEEXT_* macros directly, use...
4447 (_AC_COMPILER_EXEEXT_TESTS): ... this new macro.
4448 (_AC_COMPILER_EXEEXT_O): Don't export ac_cv_exeext, it's not needed (or
4449 no longer needed) by libtool. Make it a cache check.
4450 (_AC_COMPILER_EXEEXT_CROSS): Remove the comment, it was obviously
4451 copied here by mistake.
4452 (AC_NO_EXECUTABLES): Redefine _AC_COMPILER_EXEEXT_TESTS, not
4453 _AC_COMPILER_EXEEXT.
4454 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX, AC_PROG_OBJC): Do not call
4455 _AC_COMPILER_OBJEXT directly.
4456 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
4458 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4460 * doc/autoconf.texi (Limitations of Usual Tools) < sed (`t')>:
4461 Fix description of how the buggy `sed' works.
4463 2006-05-25 Noah Misch <noah@cs.caltech.edu>
4467 * lib/Autom4te/XFile.pm (lock): Allow EOPNOTSUPP, besides
4468 ENOLCK. Only mention `make -j' when applicable. Only raise
4469 fatal errors when `make -j' is involved. Improve error message.
4471 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4473 * doc/autoconf.texi (Here-Documents): We now know more about
4474 the variable expansion in here documents bug.
4475 Thanks to Tim Rice and Stepan Kasal.
4477 * doc/autoconf.texi (Making testsuite Scripts): Add an example
4478 how to use TESTSUITEFLAGS. Suggested by Eric Blake.
4480 2006-05-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4482 * tests/autotest.at (Multiline command from M4 expansion):
4483 No failure to be expected if the shell quotes newlines in
4484 commands in the `set -x' output. Report by Tim Rice.
4487 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
4489 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Don't use shell
4490 expansion in the here-documents used by config.status, as that
4491 runs afoul of the Korn shell version M-12/28/93d bug described in
4492 the Autoconf manual, and this in turn causes a Coreutils 5.95 build to
4493 fail as described by Tim Rice and diagnosed by Ralf Wildenhues in
4494 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00082.html>.
4496 2006-05-23 Jim Meyering <jim@meyering.net>
4498 * lib/autoconf/functions.m4 (AC_FUNC_LSTAT_FOLLOWS_SLASHED_SYMLINK):
4499 Fix typo introduced with 2006-04-02 change. It reversed the sense
4502 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
4504 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Simplify ac_dA and
4505 ac_dB slightly, to save bytes in the script.
4506 Max out at 50 lines, rather than 96; this is more likely
4507 (though not guaranteed) to avoid obscure 'sed' failures.
4509 2006-05-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4511 * lib/autotest/general.m4 (AT_INIT): UnixWare `tr' may interpret
4512 `tr -d -' as bad option argument. Work around this by deleting
4513 an unrelated character.
4514 Report by Tim Rice <tim@multitalents.net>.
4516 2006-05-22 Paul Eggert <eggert@cs.ucla.edu>,
4517 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
4518 Stepan Kasal <kasal@ucw.cz>
4520 * doc/autoconf.texi (Particular Programs): Do not promise that
4521 we always prefer the GNU version of the program, and that we
4522 search according to PATH; both rules can have exceptions.
4523 Update description of AC_PROG_GREP, AC_PROG_EGREP, AC_PROG_FGREP,
4524 AC_PROG_SED. Move descriptions of limitations
4525 to the Limitations of Usual Tools section.
4526 (Limitations of Usual Tools) <sed>: Mention script length
4527 limitations with Solaris /usr/ucb/sed.
4528 <grep>: Fix wording for empty alternative. Mention that -c and
4529 -l should not be combined, and that -E and -F should not be
4532 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
4533 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4535 * lib/autoconf/programs.m4 (AC_PROG_SED): Catch script length
4536 limits in Solaris 8 /usr/ucb/sed by testing a long script.
4538 2006-05-22 Stepan Kasal <kasal@ucw.cz>
4540 * doc/autoconf.texi (Defining Symbols): Literal parameter of
4541 AC_DEFINE is now passed to m4_pattern_allow.
4542 * NEWS: Mention that; likewise for AC_SUBST.
4543 * lib/autoconf/general.m4 (AC_DEFINE_TRACE_LITERAL): Pass
4544 the parameter to m4_pattern_allow.
4545 * tests/tools.at: Add a check for that.
4547 2006-05-22 Stepan Kasal <kasal@ucw.cz>
4549 * lib/autoconf/status.m4: Fix typos.
4551 2006-05-21 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4553 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Remove
4554 only the files that this macro generates.
4556 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
4558 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: For
4559 the HP-UX sed limitation of 99 commands, labels do not count.
4560 * lib/autoconf/status.m4 (_AC_SED_CMD_LIMIT): Mention that
4562 (_AC_OUTPUT_HEADER): Revert the change from 2006-05-19.
4564 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
4566 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT):
4567 Import the following fix from coreutils:
4569 2006-01-13 Jim Meyering <jim@meyering.net>
4571 Invoke AC_CHECK_FUNCS(getmntent) unconditionally so that tests of
4572 $ac_cv_func_getmntent (e.g., in gl_LIST_MOUNTED_FILE_SYSTEMS) need
4573 not double-quote uses of that variable, to accommodate the rare
4574 case in which getmntent is available in none of the libraries
4575 checked. This happens at least on FreeBSD 5.0.
4577 2006-05-20 Paul Eggert <eggert@cs.ucla.edu>
4579 * lib/autoconf/general.m4 (AC_CONFIG_AUX_DIRS): Bring back
4580 ac_config_guess, ac_config_sub, and ac_configure, since evidently
4581 some other programs unwisely rely on these undocumented vars.
4582 But put in warning comments about them.
4583 Problem reported by Ralf Wildenhues in
4584 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00068.html>.
4585 * NEWS: Document that these variables are intended to go away.
4587 2006-05-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4589 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): Require AC_PROG_CXX,
4590 and set the language to C++ (analogous to the equivalent Fortran
4593 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): New macro.
4594 * doc/autoconf.texi (C++ Compiler): Document it.
4595 * lib/autoconf/fortran.m4 (_AC_PROG_FC_C_O): Adjust comment.
4598 2006-05-19 Paul Eggert <eggert@cs.ucla.edu>
4600 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Fix off-by-one bug
4601 that caused config.status to generate 100-command sed scripts; the
4602 portable limit is 99.
4604 2006-05-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4606 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Name temporary
4607 variable `ac_d' instead of `d' to avoid infringing namespace.
4608 Report by Ralf Menzel.
4610 2006-05-18 Paul Eggert <eggert@cs.ucla.edu>
4612 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Don't prepend
4613 $ac_top_build_prefix to $MKDIR_P if it's just 'mkdir -p'.
4614 * tests/tools.at (autoconf: subdirectories): New test, taken from
4615 the corresponding problem report by Ralf Wildenhues in:
4616 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00053.html
4618 * lib/autoconf/functions.m4 (AC_REPLACE_FNMATCH, AC_FUNC_FNMATCH_GNU):
4619 Quote some uses of shell variables if they might suffer unexpected
4620 globbing. This doesn't fix all instances of quoting problems that
4621 I found, just the easy ones that look safe.
4622 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR, _AC_INIT_HELP):
4623 (AC_CONFIG_AUX_DIR, AC_CONFIG_AUX_DIR_DEFAULT, AC_CONFIG_AUX_DIRS):
4624 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST, AC_CANONICAL_TARGET):
4625 (AC_CACHE_LOAD, AC_CACHE_SAVE): Likewise.
4626 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF, _AC_PATH_X_DIRECT): Likewise.
4627 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Likewise.
4628 * lib/autoconf/status.m4 (_AC_OUTPUT_LINK, _AC_OUTPUT_SUBDIRS):
4630 * lib/autotest/general.m4 (_AC_INIT_PARSE_ARGS): Likewise.
4631 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Likewise.
4633 2006-05-18 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4635 * bin/autoreconf.in ($help): Reword according to the manual.
4636 Suggested by Olly Betts.
4638 2006-05-17 Olly Betts <olly@survex.com> (tiny change)
4639 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4641 * bin/autoreconf.in: Pass the directory argument to
4642 `require_configure_ac'. Fix comment.
4643 * tests/torture.at (Configuring subdirectories): Expose this.
4644 Reported by Olly Betts.
4646 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4648 * lib/Automake/Configure_ac.pm, lib/Automake/Channels.pm,
4649 lib/Automake/FileUtils.pm, lib/Automake/Struct.pm: Sync from
4650 Automake as follows:
4652 * lib/Autom4te/Configure_ac.pm (find_configure_ac): Use
4653 `$configure_in' instead of `configure.in', to preserve
4654 directory component.
4656 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4658 * config/config.guess, config/config.sub, config/texinfo.tex,
4659 doc/make-stds.texi, doc/standards.texi: Sync from upstream.
4661 2006-05-14 Paul Eggert <eggert@cs.ucla.edu>
4663 * lib/autoconf/headers.m4 (AC_HEADER_STDBOOL): Fix overly-picky
4664 test for C99 conformance; (bool) 0.5 is an integer constant
4665 expression, but (bool) -0.5 is not. Problem reported by Fedor
4666 Sergeev in <http://forum.sun.com/jive/thread.jspa?threadID=96202>.
4668 2006-05-13 Paul Eggert <eggert@cs.ucla.edu>
4670 * doc/autoconf.texi (Particular Programs): AC_PROG_MKDIR_P now
4671 sets MKDIR_P, not mkdir_p, to avoid collisions with Automake.
4672 Warn about obsolete install-sh files. Remove stray sentence
4673 fragment and fix cross reference.
4674 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Don't insist on
4675 install -d; this undoes the 2006-05-10 change.
4676 (MKDIR_P): Mark with AN_MAKEVAR.
4677 (AC_PROG_MKDIR_P): Fall back on $ac_install_sh, not $INSTALL, so
4678 that we don't require $INSTALL to be thread-safe. Move comments
4679 out of generated code. Require AC_CONFIG_AUX_DIR_DEFAULT instead
4680 of AC_PROG_INSTALL. Output a message saying that we're checking
4681 mkdir -p. Set MKDIR_P rather than mkdir_p. Do special magic for
4682 MKDIR_P instead of AC_SUBST.
4683 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE, _AC_OUTPUT_CONFIG_STATUS):
4684 Special magic for MKDIR_P, too.
4685 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Remove comment that defeated
4687 * tests/local.at (AT_CHECK_ENV): mkdir_p -> MKDIR_P.
4689 2006-05-11 Paul Eggert <eggert@cs.ucla.edu>
4691 Sync from Automake, as follows:
4693 2006-05-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4694 * config/install-sh: Initialize IFS, so field splitting isn't
4696 * config/mkinstalldirs: Likewise.
4697 * config/missing: Remove superfluous quotes. Replace all uses of
4698 `[' by `test', for consistency, and for..
4699 * config/missing (sed_minuso, sed_output): New variables.
4700 (autom4te, help2man, makeinfo): Use them. Unifies detection of
4701 `-o FILE', `--output FILE', `--output=FILE', stricter regex.
4702 Fixes `missing' to detect `--output' for help2man. Fixes
4703 PR automake/483. Report by Dennis J. Linse.
4704 (autom4te): Document in `missing --help'.
4706 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
4708 * NEWS: New macro AC_PROG_MKDIR_P. AS_MKDIR_P is now more robust.
4709 * config/install-sh: Don't use 'path' to talk about file names,
4710 as per GNU coding standards. Close a race condition reported by Ralf
4711 Wildenhues and Stepan Kasal. There is still a race condition
4712 on hosts that predate Posix 1003.1-1992, but we can't help this.
4713 Don't mishandle weird characters like space on pre-Posix hosts.
4714 Invoke mkdir at most once per dir arg on pre-Posix hosts.
4715 * doc/autoconf.texi (Programming in M4sh): Cross-reference to
4716 AC_PROG_MKDIR_P from AS_MKDIR_P.
4717 (Limitations of Usual Tools): Cross-reference to AC_PROG_MKDIR_P
4718 from mkdir. Mention that Autoconf 2.60 install-sh is safe but
4719 earlier editions are not (including Automake 1.8.3).
4720 Do not suggest mkinstalldirs for thread-safety.
4721 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Insist on an 'install'
4722 that understands -d, so that AC_PROG_MKDIR_P can fall back on $INSTALL.
4723 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Make it more robust in the
4724 presence of special characters and race conditions.
4725 * tests/local.at (AT_CHECK_ENV): Add mkdir_p to the list of variables
4726 in Autoconf's name space.
4728 2006-05-10 Bruno Haible <bruno@clisp.org>
4729 and Paul Eggert <eggert@cs.ucla.edu>
4731 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): New macro, taken
4732 from Automake with minor changes.
4733 * doc/autoconf.texi (Particular Programs): Document AC_PROG_MKDIR_P.
4735 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
4737 * config/install-sh: Update to Automake CVS version, as follows:
4738 2006-04-25 Stepan Kasal <kasal@ucw.cz>
4739 * lib/install-sh: Simplify the expr implementation of dirname.
4740 2006-04-24 Paul Eggert <eggert@cs.ucla.edu>
4741 * lib/install-sh: Handle --, and diagnose unknown options.
4743 2006-05-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4745 * tests/Makefile.am (AUTOTEST): Use `$(MY_AUTOM4TE)' instead of
4746 `./autom4te' to create `./testsuite', since the `all' target
4747 will ensure its presence, but `installcheck' should not create
4748 the uninstalled wrappers.
4750 * tests/torture.at (Unusual Automake input files): Skip if we
4751 detect automake < 1.8.
4753 2006-05-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4755 * lib/autoconf/c.m4 (AC_PROG_CC_STDC): If ac_cv_prog_cc_stdc
4756 is set to `no', then that overrides and sets ac_cv_prog_cc_c89
4757 and ac_cv_prog_cc_c99 to `no', for backward compatibility.
4760 2006-05-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4762 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Take care not to
4763 munge (multiple) white space and other oddities.
4764 * tests/torture.at (AT_CHECK_AC_ARG_VAR): Make sure to M4-escape
4765 single quotes in variable assignment.
4766 (AC_ARG_VAR, configure invocation): Adjust tests to expose this
4767 and similar failures by adding multiple spaces, tabs, and other
4769 Report and different test suggested by Francesco Romani
4770 <fromani@gmail.com> and Andrew Church <achurch@achurch.org>.
4772 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): When we escape
4773 single quotes, we only need to search for single quotes; this
4774 both simplifies the search pattern, and makes us less
4775 susceptible to `echo' variations for arguments not containing
4777 (_AC_ARG_VAR_VALIDATE): Likewise.
4779 2006-05-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4781 * doc/autoconf.texi (Special Shell Variables) <IFS>: Document
4782 `$*' and IFS concatenation issue with traditional shells and
4783 bash-2.04. Report by Seanster@Seanster.com.
4785 2006-05-03 Bruno Haible <bruno@clisp.org>
4787 * doc/autoconf.texi (Limitations of Usual Tools): Identify more
4788 precisely which Mac OS X versions have the od problem.
4790 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
4792 * doc/autoconf.texi: Use @option systematically.
4794 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>

4863 * bin/autoconf.as (me): Replace by as_me.
4865 2006-04-25 Paul Eggert <eggert@cs.ucla.edu>
4867 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Don't use AS_ERROR,
4868 since as_me isn't set yet.
4870 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
4872 Prepare for deprecation of AS_BASENAME and AS_DIRNAME, and fix
4873 a few minor bugs in this area.
4875 * doc/autoconf.texi (Programming in M4sh): Comment out the
4876 documentation of AS_BASENAME, for now.
4877 (Shell Substitutions): Do not use AS_DIRNAME in an example.
4878 (Limitations of Builtins) <basename>: Do not refer to
4880 * bin/autoconf.as (me): Don't use AS_BASENAME.
4881 (dir): Remove the unused variable.

4896 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
4898 * doc/autoconf.texi (Runtime): Renamed from "Run Time". All uses
4899 of "run time" and "run-time" changed to "runtime", for consistency.

4906 with more accuracy and detail.
4908 2006-04-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4910 * doc/autoconf.texi (Introduction): The GNU Autoconf Macro
4911 Archive is not officially `GNU' any more. Update URL.
4912 (Defining Directories): Likewise
4913 * lib/autoconf/c.m4 (AC_C_RESTRICT): Update URL.
4915 2006-04-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4917 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Remove the leading
4918 newline from the `trap' code to finish `config.log'; the NetBSD
4919 /bin/sh resets the exit status after an empty command, as
4920 documented in doc/autoconf.texi.
4921 Reported by Dalibor Topic <robilad@kaffe.org>.
4923 2006-04-19 Paul Eggert <eggert@cs.ucla.edu>
4925 * doc/autoconf.texi (C Compiler): Clarify AC_C_TYPEOF.
4926 Suggested by Bruno Haible.
4928 2006-04-18 Paul Eggert <eggert@cs.ucla.edu>
4930 * configure.ac (ac_cv_sh_n_works): Don't try to test for it, since
4931 some shells (e.g., Solaris 8 /bin/sh) implement it verrrry slowly.
4932 Instead, just list the shells that we know work.
4933 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Remove 2nd arg. All uses
4934 changed. Be more cautious about the _cv_ variable.
4935 * tests/tools.at (Syntax of the shell scripts): Check the
4936 _cv_ variable once, at first, to avoid an internal autoconf error
4937 when sh -n does not work.
4939 2006-04-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4941 * lib/Autom4te/FileUtils.pm: Sync from Automake.
4943 2006-04-16 Paul Eggert <eggert@cs.ucla.edu>
4945 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Don't
4946 use ">&-" since we're only 99.999% sure that this is portable,
4947 and since the MinGW bug is fixed in a different way.
4948 * lib/autotest/general.m4 (AT_INIT): Likewise.
4950 2006-04-16 Stepan Kasal <kasal@ucw.cz>
4952 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Handle --recheck
4953 before opening config.log, to avoid hitting a bug on MinGW.
4955 2006-04-14 Paul Eggert <eggert@cs.ucla.edu>
4957 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Close
4958 AS_MESSAGE_LOG_FD before reopening it onto the log file.
4959 This works around a MinGW bug reported by Eric Paire.
4960 Make sure that all writes to the log file append to it,
4961 rather than possibly losing data.
4962 * lib/autotest/general.m4 (AT_INIT): Likewise.
4964 2006-04-14 Stepan Kasal <kasal@ucw.cz>
4966 * lib/Autom4te/FileUtils.pm (find_file): Fix a typo in the
4969 2006-04-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4973 * configure.ac (AC_INIT): Bump to 2.59d.
4975 2006-04-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4979 * Makefile.maint (news-date-check): Do not require a leading `*'
4980 before the release date in NEWS.
4982 2006-04-12 Stepan Kasal <kasal@ucw.cz>
4983 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4985 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If the templates for
4986 the instantiated file do not contain the string 'datarootdir'
4987 but contain @datadir@, @docdir@, @infodir@, @localedir@, or
4988 @mandir@, replace the reference '${datarootdir}' by the value.
4989 * tests/torture.at (datarootdir workaround): New test.
4990 * NEWS: Advertise this temporary fixup.
4991 Based on a patch by Bruno Haible, reported and analyzed by
4992 Paul Eggert and Noah Misch.
4994 2006-04-12 Eric Blake <ebb9@byu.net>
4996 * tests/autotest.at (Debugging a failed test): Fix comment.
4998 2006-04-12 Stepan Kasal <kasal@ucw.cz>
5000 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): Simplify the summary of
5001 all the changes since 2006-04-07.
5003 2006-04-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5005 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): If `ln -s file1 file2'
5006 succeeded, but `ln -s file dir' failed, take care to remove the
5007 leftover target before the next test, to prevent its spurious
5008 failure; also make sure `ln file dir' works before selecting it.
5009 Thanks to Keith Marshall for pointing this out.
5012 * lib/autotest/general.m4 (AT_INIT): Store quoted variable
5013 assignments in `at_debug_args', so that we put them correctly
5014 in the `run' script.
5015 * tests/autotest.at (Debugging a failed test): Unmark XFAIL.
5016 Reported by Eric Blake.
5018 2006-04-11 Eric Blake <ebb9@byu.net>
5020 * tests/autotest.at (AT_CHECK_AT): Add new argument, to allow
5021 top-level tests after micro-suite has been run. Used in...
5022 (Debugging a successful test, Debugging script and environment),
5023 (Debugging a failed test): ...these new tests. The first of these
5025 * lib/autotest/general.m4 (_AT_CREATE_DEBUGGING_SCRIPT): New
5026 macro, split out from...
5027 (AT_INIT): ...here, so that using -d also generates a run script.
5028 Document that -d inhibits top-level logging.
5029 * doc/autoconf.texi (testsuite Invocation): Document that -d only
5030 inhibits top-level logging; debug scripts are created.
5032 * lib/autotest/general.m4 (_AT_CHECK): Avoid syntax error on empty
5034 * tests/autotest.at (Empty test, Empty check): New test to check it.
5036 * lib/autoconf/c.m4 (AC_C_CONST, AC_C_VOLATILE): Avoid warnings
5039 2006-04-10 Stepan Kasal <kasal@ucw.cz>
5041 * tests/mktests.sh: Use "trap '' 0", not "trap 0". Do not touch
5042 the files if a problem appears. Make the empty *.at files
5043 read-only, too. Proposed by Ralf Wildenhues.
5045 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5047 * config/Makefile.am: Add comment to force updated Makefile.in.
5049 * lib/freeze.mk: Fix typo in comment. Unlike the last, white
5050 space only patch to this file, this patch causes the Makefile.in
5051 files that include freeze.mk to be updated, and thus have a
5052 newer time stamp again, which in turn makes a pristine CVS
5053 checkout have correct time stamps.
5055 * Makefile.maint (cvs-sv): New macro, to be used..
5056 (config.guess-url_prefix, config.sub-url_prefix)
5057 (texinfo.tex-url_prefix, standards.texi-url_prefix): ..here;
5058 point to CVS text checkout of Gnulib files.
5059 (copyright-check): Bump current year.
5060 (announcement): Do not hard-wire `./announce-gen'.
5061 (cvs-update): Propagate failures of `cvs' and `move-if-change'
5063 * Makefile.cfg (executable-update): Use `chmod a+x' instead of
5065 (wget_files): Update config.guess, config.sub, texinfo.tex by
5066 `wget-update', now that their URLs work again.
5068 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
5070 * doc/autoconf.texi (Particular Types): Don't use AC_CHECK_TYPE.
5071 Problem noted by Paul D. Smith.
5073 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5075 * doc/autoconf.texi: Remove unused words from word list.
5076 * .x-sc_prohibit_atoi_atof, .x-sc_space_tab, .x-sc_sun_os_names,
5077 .x-sc_trailing_space: New files.
5079 * doc/standards.texi: Sync from gnulib.
5081 * NEWS, doc/autoconf.texi (AC_LIBOBJ vs LIBOBJS): Mark
5082 `LIBOBJDIR' as experimental.
5084 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): MSYS `ln -s' fails
5085 with a target directory; it's internally implemented as `cp'
5086 anyway, but since Autoconf advertises the possibility to use
5087 a target directory when LN_S is `ln -s', we need to find out.
5088 Reported by Rolf Ebert <rolf.ebert.gcc@gmx.de> against MSYS,
5089 analyzed by Keith Marshall <keith.marshall@total.com>.
5093 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
5095 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Just output
5096 confdefs.h as-is. In general, if it has backslash-newline or the
5097 like, then it doesn't work either to sort or to remove empty
5100 2006-04-09 Stepan Kasal <kasal@ucw.cz>
5102 * tests/Makefile.am (AUTOCONF_FILES): Fix typo in the comment.
5104 2006-04-09 Alexandre Duret-Lutz <adl@gnu.org>
5106 * lib/autom4te.in (Automake-preselections): Preselect
5109 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>
5111 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Use '\'' for an
5112 apostrophe within a single-quoted string, as this is the usual
5113 tradition and is easier to read than '"'"'. Don't rely on the
5114 shell treating "$/" like '$/'. Use a more-consistent indenting
5117 2006-04-09 Eric Blake <ebb9@byu.net>
5119 * tests/autotest.at (Backquote command substitution),
5120 (Multiline backquote command substitution): Remove mistaken
5121 AT_NO_CMDSUBST from the 2006-03-14 patch, which was meant to be
5123 (Parenthetical command substitution, Multiline parenthetical
5124 command substitution): here.
5126 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>
5128 Import macros from gnulib (often changing their name).

5159 AC_TYPE_UINTMAX_T, AC_TYPE_UINTPTR_T, AC_TYPE_UNSIGNED_LONG_LONG_INT.
5160 (C Compiler): Move AC_C_LONG_DOUBLE to ...
5161 (Obsolete Macros): here. Under AC_LONG_DOUBLE, mention
5162 AC_TYPE_LONG_DOUBLE or AC_TYPE_LONG_DOUBLE_WIDER instead.
5163 (Posix Variants): Add AC_USE_SYSTEM_EXTENSIONS.
5164 (Coding Style). Don't mention m4_expand_once.

5201 2006-04-07 Stepan Kasal <kasal@ucw.cz>
5203 Revert the patch from 2006-04-01 and only improve
5204 _AS_DETECT_BETTER_SHELL:
5206 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Do not optimize; do not
5207 skip nonexistent directories.
5208 (_AS_DETECT_BETTER_SHELL): The optimization is moved here--try
5209 only shell candidates which exist.
5210 (AS_UNAME): No need to give three parameters to _AS_PATH_WALK.
5211 * lib/autotest/general.m4 (AT_INIT): No need to give three

5234 * doc/autoconf.texi (Programming in M4sh): Document that
5235 AS_MKDIR_P exits the script on failure.
5236 * lib/autotest/general.m4: Remove redundant AS_ERROR.
5238 2006-04-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

5257 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5259 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): Fix the detection of
5260 whether `set' quotes correctly: redirect stderr of the tested
5261 `set', and use a subshell, for Ultrix; use `sed' instead of
5262 `grep' for zsh `set' which may write binary output; match only

6207 (AC_CHECK_TARGET_TOOL): Use internal versions for ac_ct_* and
6210 2005-11-01 Stepan Kasal <kasal@ucw.cz>
6212 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Remove the comment about 8+3
6215 2005-11-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6217 * NEWS: Move AH_HEADER mention to right place.
6219 2005-10-27 Stepan Kasal <kasal@ucw.cz>
6221 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): "conftst2" -> "conftest2"
6222 * lib/autoconf/fortran.m4 (_AC_PROG_FC_C_O): Likewise.
6224 2005-10-25 Stepan Kasal <kasal@ucw.cz>
6226 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): rm -f conftst2.*, not only
6227 conftst2.$ac_objext.
6228 * lib/autoconf/fortran.m4 (_AC_PROG_FC_C_O): Likewise.
6230 2005-10-24 Stepan Kasal <kasal@ucw.cz>
6232 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Use conftst2.o instead of
6233 conftest.o, to see whether the compiler really obeys; rm the object
6234 file before and after the test and register it with ac_clean_files.
6235 * lib/autoconf/fortran.m4 (_AC_PROG_FC_C_O): Likewise.
6237 2005-10-21 Stepan Kasal <kasal@ucw.cz>
6239 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): When determining,
6240 the delimiter CEOF$ac_eof: fix quoting of CEOF[0-9]* and modify the
6241 code so that the most common case requires less forks.
6243 2005-10-20 Stepan Kasal <kasal@ucw.cz>
6245 * doc/autoconf.texi (Shell Substitutions}: Document that ${10} is

6257 * doc/autoconf.texi (Generating Sources): AC_LANG_PROGRAMS ->
6258 AC_LANG_PROGRAM, fixing a typo. Don't give details about
6259 the inner workings of AC_LANG_FUNC_LINK_TRY.
6260 * lib/autoconf/c.m4 (AC_LANG_CALL(C)): Reformat to match
6261 AC_LANG_FUNC_LINK_TRY. This involves returning the value returned
6262 by the function rather than ignoring it.
6263 (AC_LANG_FUNC_LINK_TRY(C)): Call the function rather than simply
6264 comparing its address. Intel's interprocedural optimization was
6265 outsmarting the old heuristic. Problem reported by
6268 2005-10-19 Stepan Kasal <kasal@ucw.cz>
6270 * lib/autoconf/general.m4 (AC_SUBST): Remove an obsolete comment.
6272 2005-10-05 Paul Eggert <eggert@cs.ucla.edu>
6274 * lib/m4sugar/m4sugar.m4 (_m4_map): New macro.
6275 (m4_map, m4_map_sep): Use it. Handle the empty list correctly.
6277 2005-10-04 Stepan Kasal <kasal@ucw.cz>
6279 * lib/autotest/general.m4 (AT_INIT): Really make the subtree writable
6280 before removing it (chmod -R u+rwx); there are three instances of this.
6282 2005-10-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6283 Stepan Kasal <kasal@ucw.cz>
6285 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Balance parentheses.
6286 * lib/autotest/general.m4 (AT_INIT): If the test dir already exists,
6287 make its content writable before removing it. Remove an errorneous
6288 comment from the end, where the logs of the failed tests are copied
6289 to the main log file.
6291 2005-09-27 Stepan Kasal <kasal@ucw.cz>
6293 * tests/semantics.at (AC_C_BIGENDIAN): Pass --force to autoheader,
6294 in case the computer is too quick. Double quote the configure.ac
6297 * tests/local.at (AT_CHECK_AUTOCONF): Always pass --force to prevent
6298 problems if the testsuite were running too fast.
6300 2005-09-18 Paul Eggert <eggert@cs.ucla.edu>
6302 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Look for X11/Xlib.h
6303 and XrmInitialize rather than X11/Intrinsic.h and XtMalloc
6304 (which belong to Xt, not X itself). See Debian bug 327655.
6305 * NEWS: Mention this.
6307 2005-09-07 Stepan Kasal <kasal@ucw.cz>
6309 * lib/autoconf/c.m4 (AC_LANG_SOURCE(C)): Remove an incorrect comment.
6311 2005-09-06 Paul Eggert <eggert@cs.ucla.edu>
6313 * config/move-if-change: Don't output "$2 is unchanged";
6314 suggested by Ben Elliston. Handle weird characters correctly.
6316 2005-09-06 Stepan Kasal <kasal@ucw.cz>
6318 * lib/autoconf/libs.m4 (AC_SEARCH_LIBS): Merge the two AC_LINK_IFELSE
6319 calls, so that the final expansion of this macro is shorter.
6320 Create the conftest.$ac_ext outside the `for' loop, to speed the run.
6321 Do not use `break' in the argument to AC_LINK_IFELSE, it would skip
6322 the cleanup there. Use AS_VAR_* macros, to be more general.
6323 * tests/semantics.at (AC_SEARCH_LIBS): Check for the cleanup.
6325 * lib/autoconf/general.m4: Use AS_IF where appropriate.
6327 * lib/m4sugar/m4sh.m4 (AS_IF): Use m4_default.
6329 2005-09-01 Stepan Kasal <kasal@ucw.cz>

6342 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE):
6343 The previous patch didn't work, so try a better one.
6345 2005-08-26 Stepan Kasal <kasal@ucw.cz>
6347 * doc/autoconf.texi (Programming in M4sh) <AS_TR_CPP>: Fix m4 quoting
6348 in the example. Reported by Bruno Haible.
6349 <AS_TR_SH>: Likewise. Also modify the example to be more convincing:
6350 "if $undefined_var;" succeeds with my shell.
6352 * lib/autoconf/general.m4 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST,
6353 AC_CANONICAL_TARGET): Define by AC_DEFUN, no need to use AC_DEFUN_ONCE;
6354 but change the m4_divert_text to m4_divert_once.
6356 2005-08-25 Paul Eggert <eggert@cs.ucla.edu>
6358 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE):
6359 Work around bug in Solaris /usr/xpg4/bin/awk.
6360 The bug is present in at least Solaris 8 through 10.
6362 2005-08-24 Stepan Kasal <kasal@ucw.cz>
6364 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Simplify; rejecting
6365 some evil values and relying on the fact that $* concatenates the
6366 parameters by the first character from IFS.
6368 2005-08-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
6369 Stepan Kasal <kasal@ucw.cz>

6372 first header appears, define AH_HEADER.
6373 * doc/autoconf.texi (Configuration Headers): Document AH_HEADER.
6374 Update limitations about when to call AC_CONFIG_HEADERS.
6375 (Configuration Commands): Document that AC_CONFIG_COMMANDS_PRE
6376 parameter can call AC_SUBST, AC_DEFINE, or AC_CONFIG_FOOS; explain
6377 that AC_CONFIG_COMMANDS_PRE and AC_CONFIG_COMMANDS_POST are not
6378 ``Configuration Actions''; fix their index entries.
6380 * lib/autotest/general.m4 (AT_INIT): Process multiple keywords
6381 options correctly. Process N-M as M-N if M is smaller than N.
6382 Process ranges correctly so that N-N will run only N.
6383 Sort and uniquify the tests that will be run. If there is more
6384 than one test, reinsert the banners for the tests.
6385 * tests/autotest.at (Keywords): Unmark XFAIL.
6387 2005-08-23 Stepan Kasal <kasal@ucw.cz>
6389 * lib/autoconf/general.m4 (_AC_DEFINE_Q): Strip the parameter list
6390 before passing the macro name to AH_TEMPLATE.
6392 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): config.status
6393 now opens log after option processing; in particular, --version
6394 and --help do not touch config.log.

6406 * doc/autoconf.texi (Using Autotest, testsuite Scripts)
6407 (Autotest Logs, Writing testsuite.at, testsuite Invocation):
6410 * doc/autoconf.texi (Defining Symbols, Changed Results):
6411 Prepend to LIBS, not append, in examples.
6413 2005-08-16 Stepan Kasal <kasal@ucw.cz>
6415 When building in place, set srcdir="."; suggested by Tim Van Holder.
6417 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Do this; to recognize
6418 build in place, we need ac_pwd, and thus have to AC_REQUIRE ...
6419 (_AC_INIT_DIRCHECK): ... this macro and AC_DEFUN both of them.
6420 * lib/autoconf/status.m4 (_AC_SRCDIRS): Fix a comment: srcdir="."
6421 does not mean "no --srcdir option".
6423 2005-08-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6425 * tests/autoscan.at (autoscan): New file.
6426 * tests/suite.at: Use it.

6434 * Makefile.maint (GZIP_ENV): When checking the help text of gzip,
6435 add "2>&1"; gzip 1.2.4 prints help on stderr.
6437 2005-07-27 Stepan Kasal <kasal@ucw.cz>
6439 * lib/autotest/general.m4 (_AT_DECIDE_TRACEABLE): The symbol at_reason
6440 was pushdef'ed twice while popped only once. Push it only once.
6441 (_AT_CHECK): Cosmetic changes to the "case $at_status" command.
6443 2005-07-26 Stepan Kasal <kasal@ucw.cz>
6445 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): The message is now

6450 * Makefile.maint: Update from Bison.
6452 * lib/m4sugar/m4sugar.m4 (m4_strip): Comment fix---change tab to
6453 "<tab>" in comment, so that the point is understandable.
6455 2005-07-25 Stepan Kasal <kasal@ucw.cz>
6457 Rewrite substantial part of lib/autoconf/status.m4.
6458 The main change is that CONFIG_FILES, CONFIG_HEADERS, CONFIG_LINKS,
6459 and CONFIG_COMMANDS are not processed in four separate loops.
6460 Instead, there is one main loop. This alows that the common code
6461 is expanded only once, thus config.status (and configure) is smaller.
6463 The registration mechnism in AC_CONFIG_FILES and cousins also changed;
6464 the AC_LIST_FILES and cousins macros are no longer used.
6466 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES, _AC_OUTPUT_HEADERS,
6467 _AC_OUTPUT_LINKS, _AC_OUTPUT_COMMANDS): Renamed to ...
6468 (_AC_OUTPUT_FILE, _AC_OUTPUT_HEADER, _AC_OUTPUT_LINK,
6469 _AC_OUTPUT_COMMAND): ..., respectively. These macros no longer
6470 contain the initialization, nor the for loop, nor the associated
6471 commands; all these go to ...
6472 (_AC_OUTPUT_MAIN_LOOP): ... this new macro, called from
6473 _AC_OUTPUT_CONFIG_STATUS.
6474 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST, _AC_CONFIG_SPLIT_FILE_IN):
6475 Nuked; the code was merged into _AC_OUTPUT_MAIN_LOOP.
6476 (_AC_OUTPUT_FILE): The creation of the sed script ...
6477 (AC_OUTPUT): ... and the setup of ac_vpsub goes to ...
6478 (_AC_OUTPUT_FILES_PREPARE): ... a new macro, also called from
6479 _AC_OUTPUT_MAIN_LOOP.
6480 (_AC_CONFIG_FILES, _AC_CONFIG_HEADERS, _AC_CONFIG_LINKS,
6481 _AC_CONFIG_COMMANDS): Use ...
6482 (_AC_CONFIG_FOOS): ... this new macro, which uses these ...
6483 (_AC_CONFIG_REGISTER, _AC_CONFIG_REGISTER_DEST): ... new macros.
6484 (_AC_CONFIG_FILE, _AC_CONFIG_HEADER, _AC_CONFIG_LINK,
6485 _AC_CONFIG_COMMAND, _AC_CONFIG_DEPENDENCIES): No longer needed.
6486 (_AC_CONFIG_DEPENDENCY): Update, it uses these ...
6487 (_AC_CONFIG_DEPENDENCY_DEFAULT, _AC_FILE_DEPENDENCY_TRACE_COLON):
6489 (_AC_CONFIG_UNIQUE): Update.
6490 (AC_LIST_FILES, AC_LIST_HEADERS, AC_LIST_LINKS, AC_LIST_COMMANDS):
6491 Replaced by this ...
6492 (_AC_LIST_TAGS): ... new common macro.
6493 (AC_LIST_FILE_COMMANDS, AC_LIST_HEADER_COMMANDS, AC_LIST_LINK_COMMANDS,
6494 AC_LIST_COMMAND_COMMANDS): Replaced by this ...
6495 (_AC_LIST_TAG_COMMANDS): ... new common macro.
6496 (_AC_CONFIG_COMMANDS_INIT): Moved top to the `registration' section;
6497 this didn't belong to the `config commands' section.
6498 (_AC_OUTPUT_COMMANDS_INIT): Don't initialize, m4_ifdef is our friend.
6499 (AC_CONFIG_COMMANDS_PRE, AC_OUTPUT_COMMANDS_PRE,
6500 AC_CONFIG_COMMANDS_POST): Moved to a new section, these didn't belong
6501 to the `config commands' section either.
6502 (AC_CONFIG_SUBDIRS): Don't touch diversion DEFAULTS.
6503 (_AC_LIST_SUBDIRS): Don't initialize, m4_ifdef is our friend.
6505 ... and many changes to the comments nearby.
6507 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): At the end of the day,
6508 set ac_subdirs_all='_AC_LIST_SUBDIRS'.
6509 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
6510 AC_CONFIG_COMMANDS(command:input,...) is no longer allowed.
6511 (#define header templates): The comment at the top of the generated
6512 header now includes the name(s) of the source file(s).
6514 Several unrelated small changes:
6516 * lib/autoconf/general.m4 (AC_CACHE_VAL): Be didactic, quote the first
6517 parameter to AC_DIAGNOSE.
6518 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS): Likewise.
6519 (_AC_LINK_FILES_CNT): Don't AU_DEFUN this; it causes confusing messages
6520 with autoupdate; use m4_define_default inside AU_DEFUNed AC_LINK_FILES.
6521 (AC_OUTPUT): In the compatibility code, use m4_ifvaln, to be consistent
6523 (AU::AC_OUTPUT): Don't double-quote $2 and $3, the compatibility code
6524 in AC_OUTPUT doesn't double-quote it either.
6525 * tests/tools.at (autoupdate): AU::AC_OUTPUT no longer double-quotes the
6528 2005-07-10 Stepan Kasal <kasal@ucw.cz>
6530 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Document which
6531 versions of Portland Group compiler produce single- and double-quoted
6532 -cmdline argument. Reported by Steven G. Johnson <stevenj@fftw.org>
6533 and Ole Holm Nielsen <Ole.H.Nielsen@fysik.dtu.dk>.
6535 2005-07-07 Paul Eggert <eggert@cs.ucla.edu>
6537 * tests/local.at (AT_CONFIG_CMP): Ignore lines like "LIBS=''" too.
6538 This is a corrected version of yesterday's patch.
6540 2005-07-07 Stepan Kasal <kasal@ucw.cz>
6542 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Report the full
6543 path, too; insert a "===" to emphasize the line.
6545 * lib/autoconf/general.m4 (AC_CANONICAL_BUILD): Rename
6546 ac_cv_build_alias to ac_build_alias.
6547 (AC_CANONICAL_HOST, AC_CANONICAL_TARGET): Simplify.
6549 On 2005-02-24, an unintentional AC_SUBST([CC]) was introduced; this
6550 change eliminates it. Problem reported by Alexandre Duret-Lutz.
6551 * lib/autoconf/general.m4 (_AC_ARG_VAR_PRECIOUS): Move the AC_SUBST ...
6552 (AC_ARG_VAR): ... here.
6553 (_AC_INIT_PREPARE): Call AC_SUBST for build_alias, host_alias and
6556 Keep a list of all precious variables and process them with one simple
6557 for loop, instead of expanding all commands, or, OTOH, complicated
6558 processing of output of "set".
6559 * lib/autoconf/general.m4 (_AC_ARG_VAR_PRECIOUS): Acumulate the
6560 variable names in new macro...
6561 (_AC_PRECIOUS_VARS): ... which will be assigned to ac_precious_vars.
6562 (_AC_ARG_VAR_STORE): New macro which writes to diversion PARSE_ARGS
6563 a loop to assign all ac_env_* and ac_cv_env_* variables.
6564 (_AC_ARG_VAR_VALIDATE): Use shell variable ac_precious_vars, divert
6566 (_AC_INIT_DEFAULTS): At the end, if _AC_PRECIOUS_VARS is set, assign
6567 its value to shell variable ac_precious_vars and call
6568 _AC_ARG_VAR_STORE and _AC_ARG_VAR_VALIDATE.
6569 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Don't call
6570 _AC_ARG_VAR_VALIDATE.
6572 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Move AC_LANG_PUSH(C)
6573 and the AC_SUBSTs ...

6577 the ac_subst_files section in config.log.

6595 Fix my changes from 2005-07-01; reported by Noah Misch.
6596 * lib/autoconf/status.m4 (_AC_CONFIG_DEPENDENCIES): Fix the
6597 description, the macro now accepts only a single tag.

6600 Fix cases when the varsions of Autoconf and Autotest don't match.
6601 Reported by Noah Misch.
6602 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Set also
6603 at_top_builddir, for compatibility with older autotest.
6604 * lib/autotest/general.m4 (AT_INIT): If at_top_build_prefix
6605 is not set, use at_top_builddir, for compatibility with older
6606 versions of autoconf.
6608 2005-07-04 Paul Eggert <eggert@cs.ucla.edu>
6610 * bin/autom4te.in ($m4): Catch usages like --nesting-limit=2048.
6611 Problem reported by Patrick Welche.
6613 2005-07-03 Paul Eggert <eggert@cs.ucla.edu>
6615 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Use &, not |, in
6616 sed substitution command, so that we allow | in program prefixes
6617 and program suffixes. (& is a problem anyway; we're not fixing
6619 * lib/autoconf/status.m4 (AC_CONFIG_FILES): Likewise, for
6620 configure_input, top_builddir, srcdir, etc.
6621 * lib/autotest/general.m4 (AT_INIT): Likewise, for
6622 PATH_SEPARATOR in AUTOTEST_PATH.
6624 2005-07-02 Alexandre Duret-Lutz <adl@gnu.org>
6626 * lib/autoconf/general.m4 (AC_SITE_LOAD): Rewrite the
6627 for loop over config.site files using `set', to allow
6628 directory names containing IFS characters.
6630 2005-07-01 Paul Eggert <eggert@cs.ucla.edu>
6632 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Remove the tests for
6633 directories with weird names. Apparently some people like living
6634 on the edge. However, improve the test that "pwd" actually does
6635 report a name for the working directory.
6636 * NEWS: Remove the claim that we test for funny chars in dir names.
6638 2005-07-01 Stepan Kasal <kasal@ucw.cz>

6654 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Use a here
6655 document to output the default config_* lists to config.status.
6656 Don't recognize option --file, if the functionality is not there.
6657 Likewise for --header; moreover, recognize --he and --h as shortcuts
6658 for --help in that case.
6660 * lib/autoconf/status.m4: Fix the order of the "sections", so that it
6661 matches the order of execution. No code changed.
6663 2005-06-30 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6665 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Fix also for

6676 descriptors to child processes; reported by Norman Gray.
6678 2005-06-29 Stepan Kasal <kasal@ucw.cz>
6680 * lib/autoconf/general.m4 (AC_ARG_VAR): Move next to _AC_ARG_PRECIOUS.
6682 * lib/autoconf/general.m4 (AC_SUBST_TRACE): New macro, to be traced
6683 instead of AC_SUBST; proposed by Alexandre Duret-Lutz.
6684 (AC_SUBST): Call it.
6685 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Call AC_SUBST_TRACE for
6686 the directory specific variables; but don't call it for configure_input.
6688 2005-06-28 Derek Price <derek@ximbiot.com>
6690 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: Reword recent
6693 2005-06-23 Paul Eggert <eggert@cs.ucla.edu>
6695 * NEWS: Don't worry about spaces in bindir etc. Only srcdir and working
6696 directory have inherent problems with special characters like spaces,
6697 due to limitations in Make syntax. Problem reported by Alexandre
6699 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Implement the above.
6700 Also, fix Tru64 porting problem with shell patterns,

6712 from Justace Clutter.
6713 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Put name of invalid
6714 variable into diagnostic. Make the diagnostic an error, not a warning,
6715 because we really don't support spaces and suchlike in dir names.
6716 (_AC_INIT_SRCDIR): Allow special characters in $ac_unique_file.
6717 Don't worry about backslashes in srcdir; it can't happen now.
6718 (_AC_INIT_PARSE_ARGS): Allow weird characters in ac_optarg.
6719 Simplify ac_optarg handling.

6728 (AT_CONFIG_CMP): Use sed instead of grep plumbing.
6730 * doc/autoconf.texi (Limitations of Usual Tools) <grep>: Mention
6731 that '\|' is not allowed in BREs; recommend using newline separated
6732 list of patterns instead of multiple -e options.
6734 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Remove an old comment.
6736 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Use AC_SUBST/2.

6744 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: Document that
6745 b, t, r, w commands require single space, while : cannot have any.
6746 (Special Shell Variables): Fix sed code this in the example.
6747 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Likewise; and fix a typo.
6748 * lib/autotest/general.m4 (AT_ARG_OPTION): Fix typo in the description.
6750 * lib/m4sugar/m4sugar.m4 (m4_split): If the parameter is empty,

6756 * lib/m4/programs.m4 (AC_PROG_YACC): Declare YACC & YFLAGS precious.
6758 2005-06-17 Paul Eggert <eggert@cs.ucla.edu>
6760 * lib/m4sugar/m4sh.m4 (as_awk_strverscmp): Port to Solaris /bin/awk.
6761 * doc/autoconf.texi:
6762 Don't mention Solaris versions so much, if a
6763 problem is common to all extant versions of Solaris. Say "SunOS
6764 4" instead of "SunOS" for SunOS 4.
6765 (awk): Mention more of the limitations of traditional Awk.
6766 (cat): Don't talk about cat -v.
6768 2005-06-16 Paul Eggert <eggert@cs.ucla.edu>
6770 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE): New macro.
6771 (AS_VERSION_COMPARE): New macro. The API is taken from CVS,
6772 but the implementation is entirely different and is designed
6773 to be compatible with glibc strverscmp.
6774 * tests/m4sh.at (AS_VERSION_COMPARE): New test.
6776 * doc/autoconf.texi (Limitations of Usual Tools): Mention expr bug
6777 on Mac OS X 10.4 reported by Peter O'Gorman in:

6782 2005-06-10 Paul Eggert <eggert@cs.ucla.edu>
6784 * doc/autoconf.texi: "filesystem" -> "file system".
6785 "behaviour" -> "behavior".
6786 Warn about \(...\)* in Solaris sed (written by Ralf Menzel).
6787 * lib/autoconf/general.m4: Omit blank after ":" sed command,
6789 * lib/m4sugar/m4sh.m4: Likewise.
6790 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Work around problem
6791 with Solaris sed. Fix by Ralf Menzel and Stepan Kasal.
6793 * man/Makefile.am (MOSTLYCLEANFILES): Add $(srcdir)/*.t.
6794 (.x.1): Ignore the time stamp in the .TH line when deciding whether
6795 to update the man page. That way, we don't have to check in new
6796 man pages every month.
6798 * lib/m4sugar/m4sh.m4 (AS_VAR_TEST_SET): Work even if $1 contains
6799 quotes and backslashes. Patch from Derek Price.

6806 2005-06-08 Paul Eggert <eggert@cs.ucla.edu>
6808 * lib/autotest/general.m4 (AT_INIT): Don't accept Solaris 9's diff
6809 -u, since it outputs chatter if the input files are the same.
6810 Problem reported by Ralf Menzel.
6812 2005-06-08 Derek Price <derek@ximbiot.com>
6814 * lib/m4sugar/m4sugar.m4: Undefine include & sinclude rather than
6815 renaming them since they are about to be redefined anyhow.
6817 2005-06-08 Derek Price <derek@ximbiot.com>
6819 * doc/autoconf.texi (Redefined M4 Macros): Add index entries for most
6820 redefined M4 macros to this node. Document m4_include & m4_sinclude.
6821 Move m4_undefine to alphabetical order.
6823 2005-06-07 Paul Eggert <eggert@cs.ucla.edu>
6825 * README: Recommend GNU M4 1.4.3 or later.
6826 * doc/autoconf.texi (Introduction): Likewise.
6827 Reword to avoid some formatting glitches.
6828 Use "#!/bin/sh", not "#! /bin/sh"; the space isn't needed these days.
6829 Clarify explanation of HP compiler bug.
6830 Redo example output tp match current CVS snapshot.
6831 Use @example.org in email addresses when the examples
6832 might get inadvertently cut-and-pasted into user code.
6833 Remove example of autom4te usage that doesn't seem to work now.
6834 Use modern AC_INIT (except when the example is meant to be
6835 shown with Autoconf 2.13).
6836 Update ksh info for Solaris 9 and later.
6838 Modernize description of Automake versions a bit.
6839 Don't claim a future version of Autoconf is near.
6840 * doc/install.texi: Reword to avoid some formatting glitches.
6842 2005-06-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

6845 follows its own advice about quoting better.
6846 Reword to avoid some formatting glitches.
6847 * doc/installt.exi: Reword to avoid some formatting glitches.
6849 * doc/autoconf.texi (Limitations of Builtins) <case>: Mention
6850 Tru64 ksh pattern matching bug. Reported against Libtool by
6851 Albert Chin <libtool@mlists.thewrittenword.com> and
6852 Nicolas Joly <njoly@pasteur.fr>.
6854 2005-06-06 Stepan Kasal <kasal@ucw.cz>
6856 m4_cdr of one-member list was [[]] (one-member list containing an
6857 empty string) instead of [] (an empty list. Callers were skewed to
6858 match this misbehaviour. As a consequence of this:
6859 - m4_foreach([x], [], [foo]) expanded to `foo', while
6860 - the expansion of m4_foreach([x], [[]], [foo]) was empty.
6861 This bug has been fixed:
6863 * lib/m4sugar/m4sugar.m4 (m4_cdr): If only one argument is given,
6864 expand to an empty string; print error msg if called without
6866 (m4_foreach, m4_map, m4_map_sep): Don't expect the previous
6867 misbehaviour; handle [] and [[]] correctly.
6869 2005-06-06 Stepan Kasal <kasal@ucw.cz>
6871 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Nuke ac_max_here_lines.
6872 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Simplify the sed
6873 scripts created and the loop applying them, use _AC_SED_CMD_LIMIT.
6875 2005-06-06 Ralf Menzel <menzel@ls6.cs.uni-dortmund.de> (trivial change)
6877 * doc/autoconf.texi (Limitations of Usual Tools): Solaris' awk cannot
6878 swallow records with more than 99 fields.
6879 * lib/autotest/general.m4 (AT_INIT): Use the awk builtin `split' to
6880 parse the long line.
6882 2005-06-04 Stepan Kasal <kasal@ucw.cz>
6884 * doc/autoconf.texi (Limitations of Usual Tools): AIX awk cannot
6885 swallow literals longer than 399. Reported by Ralf Wildenhues.
6886 * lib/autotest/general.m4 (AT_INIT): Pass $at_groups though stdin,
6887 to workaround this limitation.
6889 2005-06-03 Steven G. Johnson <stevenj@alum.mit.edu>
6891 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Find g95 in addition
6892 to gfortran, and make these the first two compiler names
6893 checked (following the general autoconf preference for gcc).

6897 * tests/Makefile.am (check_SCRIPTS): Set to $(wrappers).
6898 (DISTCLEANFILES): Remove $(check_SCRIPTS).
6899 (testsuite): Make sure autotest.m4f is up-to-date before using it.

6903 * lib/autotest/general.m4 (AT_INIT): Don't create a regular
6904 expression of unbounded size when processing the --list
6905 option. This runs afoul of a limit of 399 bytes per regular
6906 expression on AIX. Problem reported by Ralf Wildenhues.
6908 2005-06-01 Paul Eggert <eggert@cs.ucla.edu>

6911 * doc/autoconf.texi (Particular Headers): Reword example
6912 for multiline stdbool replacement.
6913 (Setting Output Variables): Reword text a bit. Don't
6914 give all the details about |#_!!_#|.
6915 Reword description of line replacement.
6917 2005-05-31 Dan Manthey <dan_manthey@partech.com>
6919 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Output variables may
6920 now contain newlines, and substituted files must be referenced on
6921 a line alone; the sed scripts to substitute them are now very
6923 (_AC_SED_CMD_LIMIT): Added; single place to store limit on how many
6924 commands can be put in a sed script portably.
6925 * doc/autoconf.texi (Setting Output Variables): Document above
6926 changes. (Particular Header Checks) <AC_HEADER_STDBOOL>: Give exaple
6927 use of multiline substitution.

6937 * tests/local.at: Don't attempt to check for negated character
6938 classes in shell scripts. The test was too brittle.
6940 2005-05-25 Stepan Kasal <kasal@ucw.cz>
6942 * bin/autoconf.as: Don't use "shift 2"; it's not portable enough.
6943 * doc/autoconf.texi (Limitations of Builtins): Document this
6946 2005-05-24 Stepan Kasal <kasal@ucw.cz>
6948 * lib/m4sugar/m4sh.m4 (_AS_ECHO_LOG): New macro to factor out
6949 common code; used in many places in the tree.
6950 (AS_ESCAPE): Make the pattern a bit simpler; use \& insetad of \1.
6951 (_AS_ECHO_UNQUOTED): Move the macro lower; no code change.
6953 * lib/m4sugar/m4sugar.m4 (m4_ifset): Use m4_ifval.

6956 messages when ac_unique_file is not found.
6957 (AC_CONFIG_MACRO_DIR): Simplify the `if' at the end.
6958 (AC_MSG_CHECKING, AC_MSG_RESULT): Put braces around the two echo
6959 commands, for consistency with AC_MSG_ERROR and such.

6971 2005-05-20 Stepan Kasal <kasal@ucw.cz>
6973 * NEWS: @top_builddir@ is now a dirname, ac_top_builddir will follow.
6974 * lib/autoconf/status.m4 (_AC_SRCDIRS): Rename ...
6975 (ac_top_builddir): ... this ...
6976 (ac_top_build_prefix): ... to this; the old name is also kept, for
6977 backward compatibility.
6978 (ac_top_builddir_sub): New variable, without the trailing slash,
6980 (_AC_OUTPUT_FILES): s/@top_builddir@/$ac_top_builddir_sub/

6994 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Don't m4_quote the second
6995 argument to m4_foreach. I guess it was necessary in the past,
6996 but I think it's a no-op now.

7000 * lib/autoconf/general.m4 (_AC_INIT_HELP): Merge two consecutive
7001 ``cat <<_ACEOF'' commands to one.

7081 Also, throughout this document, be more careful about white space.
7082 "blank", "white space", and "space" all have different meanings
7083 and we should be careful to say what we mean.

7128 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): A tiny optimization.
7130 2005-04-22 Stepan Kasal <kasal@ucw.cz>
7132 * doc/autoconf.texi (External Software): Quadrigraphs are not
7133 processed correctly in AS_HELP_STRING; avoid this in the examples.
7134 * lib/m4sugar/m4sh.m4 (AS_HELP_STRING): Add a FIXME about quadrigraphs.
7135 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Likewise; and rephrase the
7136 comment and reduce m4_default([foo], []) to [foo].
7137 (m4_strip): Update the explanation.
7139 2005-04-19 Paul Eggert <eggert@cs.ucla.edu>
7141 * lib/autoconf/general.m4 (_AC_INIT_PREPARE, _AC_RUN_IFELSE):
7142 Remove core.conftest.* too; it's generated by Tru64 5.1.
7143 Problem reported by Jennis Pruett.
7144 * lib/autoconf/functions.m4
7145 (AC_FUNC_SETVBUF_REVERSED, AC_FUNC_UTIME_NULL):
7146 Don't bother to remove core files; AC_RUN_IFELSE should do that
7149 2005-04-19 Stepan Kasal <kasal@ucw.cz>
7151 * lib/m4sugar/m4sugar.m4 (m4_bpatsubsts): Add the b- to comment, too.

7168 2005-04-13 Paul Eggert <eggert@cs.ucla.edu>
7170 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Look for configure.ac
7171 as well as configure.in. Problem reported by Gregorio Guidi.
7173 2005-04-10 Paul Eggert <eggert@cs.ucla.edu>
7175 * doc/autoconf.texi (Particular Functions): Use gnulib's current

7189 fails if %s isn't supported. Problem reported by Ralf Wildenhues.
7191 2005-03-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7193 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS):
7194 Merge `-z option' as well for the benefit of Solaris link flags. Pass
7195 whole-archive (-zallextract, -zdefaultextract) options in the hope of
7196 unique libraries, for the Sun Fortran 95 8.0 compiler. Bug reported
7197 against Libtool by Yury Puhalsky <pooh@cryptopro.ru>.
7199 2005-03-22 Paul Eggert <eggert@cs.ucla.edu>
7201 * NEWS: The configure command now warns you if you attempt to use
7202 a directory whose name contains a special character like space,
7204 * doc/autoconf.texi (Installation Directory Variables): Allow
7205 "," in file names. Do not use \@; it's not a portable regexp.
7206 * bin/Makefile.am (edit): Likewise.
7207 * lib/Makefile.am (edit): Likewise.
7208 * tests/Makefile.am (edit): Likewise.
7209 * tests/semantics.at: Likewise.
7210 * tests/torture.at: Likewise.
7211 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Likewise.
7212 * lib/autoconf/status.m4 (_AC_SRCDIRS): Likewise.
7213 * doc/autoconf.texi (File System Conventions): Warn about
7214 unportable file names.
7215 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): New macro.
7217 (_AC_INIT_SRCDIR): Use ac_pwd rather than invoking pwd.
7218 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Propagate
7219 ac_pwd, and quote srcdir.
7220 * lib/autotest/general.m4 (AT_INIT): Quote file name args.
7222 * doc/autoconf.texi: Fix some systematic formatting problems.
7223 ".)" needs a following @: if not at the end of a sentence, and
7224 similarly for "!)". "etc." should be preceded by a comma.
7225 "n-th" -> "@var{n}th". pdksh is still buggy, so update its date.
7227 2005-03-22 Bruno Haible <bruno@clisp.org>
7229 * doc/autoconf.texi (Input): Mention that AC_CONFIG_AUX_DIR's
7230 argument is often called 'build-aux'.
7232 2005-03-07 Stepan Kasal <kasal@ucw.cz>
7234 * doc/autoconf.texi (Quotation Rule Of Thumb): Mention that the
7235 macro AC_TRY_LINK is obsolete.
7236 (Installation Directory Variables): Change `AC_OUTPUT_FILES' to
7239 2005-02-24 Stepan Kasal <kasal@ucw.cz>
7241 * lib/autoconf/c.m4 (AC_PROG_CC): Be more careful to skip
7242 `/usr/ucb/cc'; use `cl.exe' to distinguish the MS compiler
7243 from a Common Lisp's `cl'.
7244 (AC_PROG_CXX): Behave according to the documentation: don't
7245 search for $ac_tool_prefix$CCC and $CCC, just set CXX=$CCC;
7246 make the variable CCC precious; use `cl.exe', not `cl'.
7248 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
7249 Alexandre Duret-Lutz <adl@gnu.org>
7251 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin from
7252 /dev/null, as "configure" shouldn't read stdin, and this insulates
7253 us from problems (e.g., when testing for "cl"). Also, do this
7254 redirection before invoking "hostname" or "uname", and keep the
7255 original input stream available via...
7256 (AS_ORIGINAL_STDIN_FD): ... this new macro.
7257 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't
7258 bother with "</dev/null" since it's now done at the top of
7260 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Likewise.
7261 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.

7267 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
7269 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N_PREPARE): Don't set ECHO_C to
7270 newline if neither \c nor -n work, as that would output two
7271 newlines. Prefer -n to \c. Reported by Stepan Kasal.
7273 2005-02-12 Stepan Kasal <kasal@ucw.cz>
7275 * lib/m4sugar/m4sh.m4 (AS_IF): Define by m4_defun, not m4_define.
7276 This causes that any required macros inside will get before the if.
7277 * doc/autoconf.texi (autom4te.cache): A typo.
7279 2005-02-12 Paul Eggert <eggert@cs.ucla.edu>
7281 Undo previous change, except keep the change to
7282 lib/autoconf/programs.m4 that replaced grep with shell
7283 pattern-matching. This is because net-snmp configure reads stdin.
7284 Reported by Noah Misch.
7286 2005-02-11 Paul Eggert <eggert@cs.ucla.edu>
7288 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin
7289 from /dev/null, as "configure" shouldn't read stdin, and this
7290 insulates us from problems (e.g., when testing for "cl").
7291 Suggested by Alexandre Duret-Lutz. Also, do this redirection
7292 before invoking "hostname" or "uname".
7293 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
7294 _AC_LINK_IFELSE): Undo previous change, as it's no longer needed.
7295 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Don't bother with
7296 "</dev/null" since it's now done at the top of 'configure'.
7297 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
7298 * lib/autoconf/programs.m4 (_AC_PATH_PROG_FLAVOR_GNU): Likewise.
7299 Also, replace grep with shell pattern-matching, to save a process.
7301 2005-02-10 Paul Eggert <eggert@cs.ucla.edu>
7303 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
7304 _AC_LINK_IFELSE): Redirect stdin to /dev/null, in an attempt to
7305 avoid thinking that Allegro Common Lisp's "cl" command is a C++
7308 2005-02-09 Paul Eggert <eggert@cs.ucla.edu>
7310 * doc/autoconf.texi (Limitations of Usual Tools): Document that
7311 grep -q isn't portable. Improve grep -s explanation.
7312 Problem reported by Dan Manthey.
7314 2005-02-08 Paul Eggert <eggert@cs.ucla.edu>
7316 * doc/autoconf.texi (Special Shell Variables): Clarify
7317 PATH_SEPARATOR wording; fix typo in IFS. Reported by Gary V. Vaughan.
7319 2005-02-07 Paul Eggert <eggert@cs.ucla.edu>
7321 * doc/autoconf.texi: Use @acronym for DJGPP.
7322 Fix some @code's that should have been @env's, and vice versa.
7323 Sort environment variable names.
7324 Mention that shells no longer inherit IFS.
7325 Don't recommend PATH_SEPARATOR=';' so strongly.
7326 Mention that $RANDOM might expand to the empty string.
7327 "symlink" and "soft link" -> "symbolic link".
7328 Improve mktemp description (reported by Bruno Haible).
7330 2005-02-05 Paul Eggert <eggert@cs.ucla.edu>
7332 * tests/foreign.at (Libtool): Don't overquote AT_SETUP arg.
7333 * tests/m4sh.at (AS_DIRNAME, AS_BASENAME, AS_MKDIR_P, AS_HELP_STRING):
7335 * tests/semantics.at (AC_C_BIGENDIAN, AC_PATH_PROG & AC_PATH_PROGS):
7338 2005-02-04 Paul Eggert <eggert@cs.ucla.edu>
7340 * NEWS: Mention AT_COPYRIGHT.
7342 * tests/local.at (AT_CMP): Use diff directly on input files rather
7345 * lib/autoconf/programs.m4 (AC_PROG_SED): Don't look in
7346 /usr/xpg4/bin since that sed dumps core (at least on Solaris 8).
7348 2005-02-04 Noah Misch <noah@cs.caltech.edu>
7349 and Paul Eggert <eggert@cs.ucla.edu>
7351 * tests/autotest.at (Empty test suite): New test.
7352 * tests/torture.at (Substitute and define special characters)
7353 (Substitute a 2000-byte string, Define to a 2000-byte string)
7354 (Substitute a newline, Define a newline): New tests.
7356 2005-02-04 Noah Misch <noah@cs.caltech.edu>
7358 * lib/m4sugar/m4sugar.m4 (m4_re_string, m4_re_word): Revert 2002-03-04.
7359 * tests/local.at (AT_CHECK_M4SUGAR): Add `m4sugar' to keywords.
7360 (AT_CHECK_ENV): Ignore LTLIBOBJS, FC variables, EGREP, FGREP, and SED.
7361 * tests/m4sugar.at (AT_CHECK_M4SUGAR_TEXT, AT_CHECK_M4RE): New macros.
7362 (Standard regular expressions): New test.
7363 (m4_warn, m4_require: circular dependencies, m4_text_wrap): Strip
7364 excess test name quoting.
7365 * tests/semantics.at (AC_CHECK_HEADERS_OLD, AC_CHECK_HEADERS_NEW): Pass
7366 CPPFLAGS to `configure' instead of setting it in `configure'.
7368 * lib/m4sugar/m4sh.m4 (AS_UNAME): Try only /usr/bin/hostinfo, not
7369 any `hostinfo' in $PATH, since hostinfo.exe is a popular file name
7372 * lib/autoconf/fortran.m4 (AC_LANG(Fortran), AC_FC_SRCEXT):
7373 s/FC_SRCEXT/ac_fc_srcext/; s/FCFLAGS_SRCEXT/ac_fcflags_srcext/.

7380 (AT_CHECK_MACRO): Run `configure' twice with cache and compare results.
7381 * tests/c.at (Extensions): Do not exit early.

7403 * lib/m4sugar/m4sugar.m4 (m4_re_escape): Escape ?, ^, \, $ too;
7404 this fixes a bug tickled by the AT_CAPTURE_FILE change noted below.
7406 Try not to generated lines of unlimited length, as POSIX places a
7407 2047-byte limit on line length of portable text files.
7408 * lib/autoconf/general.m4 (AC_SUBST, AC_SUBST_FILE):
7409 Use newline as a separator, not space.

7418 are restored after function return.
7420 2005-02-02 Paul Eggert <eggert@cs.ucla.edu>
7422 * doc/autoconf.texi (Special Shell Variables): Mention _,
7423 BIN_SH, DUALCASE. Say that variables other than "status" are safe
7424 if they contain a lower-case letter. The DUALCASE problem was
7425 reported by Ralf Wildenhues.
7427 * bin/autoconf.as: Don't exit with status 0 after write failure
7428 with --help or --version.
7429 * lib/autoconf/general.m4 (_AC_INIT_HELP, _AC_INIT_VERSION): Likewise.
7430 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Likewise.

7435 Unicos 9 sed limitations.
7436 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Try cf77 before fort77
7437 to get the option-enhanced interface on older Crays. Try ftn for
7438 Fortran 95 (newer Crays).
7440 2005-02-01 Paul Eggert <eggert@cs.ucla.edu>
7442 * man/Makefile.am (.x.1): Go back to the simple solution, but take
7443 care to echo the commands, so the user knows what's going on.
7444 Modified from a suggestion by Stepan Kasal.
7446 * doc/autoconf.texi (autoreconf Invocation): Mention autopoint,
7447 with a cross reference. Derived from a suggestion by Bruce Korb.

7454 Based on a proposed patch by Ralf Wildenhues.
7456 * man/Makefile.am (.x.1): Make sure the required generated files
7457 are up to date. Problem and original solution proposed by Stepan Kasal.
7458 $(dist_man_MANS:.1=-bin-prereq), $(dist_man_MANS:.1=-tests-prereq),
7459 implicit-man-prerequisites): New rules, used by the above.

7465 2005-01-29 Stepan Kasal <kasal@ucw.cz>
7467 Simplify the implementation of m4_require (a.k.a. AC_REQUIRE).
7468 Update the long comment explaining it.
7470 m4_require no longer writes an ``is required by'' line to the
7471 execution stack. It contains only one bit of non-redundant
7472 information: that the macro was required, not called. And even
7473 this bit is useless in most situations: have you ever met a macro
7474 which both calls and requires the same macro?
7476 * lib/m4sugar/m4sugar.m4 (_m4_defun_pro): Don't push a diversion...
7477 (_m4_defun_pro_outer): ... only via this macro, for the outermost
7479 (_m4_defun_epi, _m4_defun_epi_outer): Complementarily.
7480 (m4_expansion_stack_pop): Remove the misplaced comment.
7481 (m4_require): Don't put the ``is required by'' line to the
7482 execution stack; slightly improve the out-of-a-defun error message.
7483 (_m4_divert_grow): New macro, counter for the temporary diversions.
7484 (_m4_require_call): Use it.
7485 * tests/m4sugar.at (m4_require): Expect output without the
7486 ``is required by'' messages.
7488 2005-01-28 Paul Eggert <eggert@cs.ucla.edu>
7490 * doc/autoconf.texi (Limitations of Usual Tools): Recommend X
7491 rather than x for expr.
7493 * lib/autoconf/lang.m4 (_AC_COMPILER_OBJEXT): Avoid subshells when
7495 * lib/autoconf/programs.m4 (AC_PROG_EGREP, AC_PROG_FGREP): Likewise.

7506 * lib/Autom4te/Channels.pm, lib/Autom4te/Configure_ac.pm
7507 * lib/Autom4te/FileUtils.pm, lib/Autom4te/XFile.pm: Update
7508 from masters, so that FileUtils.pm's update_file provide --force
7510 * bin/autoheader.in: Pass $force to update_file so that
7511 config.h.in is always recreated when --force.
7513 2005-01-24 Stepan Kasal <kasal@ucw.cz>
7515 * doc/autoconf.texi (Introduction): Update Peter Simons' address.
7517 2005-01-21 Paul Eggert <eggert@cs.ucla.edu>
7519 * doc/autoconf.texi (Limitations of Builtins): Clarify that
7520 "if test ! -d foo; ..." is portable. Suggested by Stepan Kasal.
7522 2005-01-20 Paul Eggert <eggert@cs.ucla.edu>
7524 * doc/autoconf.texi (Shell Substitutions): Fix typo in case statement.
7525 Warn about newline stripping in `` and $(). Update Solaris
7527 (Limitations of Builtins): Use expr "X...", not expr "x...", as
7528 X insulates us from future changes to Posix.
7529 (Limitations of Usual Tools): For AS_DIRNAME, warn about newline
7532 2005-01-19 Stepan Kasal <kasal@ucw.cz>
7534 * doc/autoconf.texi (Defining Symbols): Delete the false comment that
7535 you cannot use AC_DEFINE to define macros containing `[' or `]'.
7537 2005-01-13 Paul Eggert <eggert@cs.ucla.edu>
7539 * doc/autoconf.texi (Limitations of Usual Tools): Document bug
7540 in Solaris 8 join. Problem reported by Tomohiro Suzuki on
7541 bug-tar mailing list.

7547 2005-01-05 Paul Eggert <eggert@cs.ucla.edu>
7549 * lib/autoconf/c.m4 (AC_LANG_INT_SAVE(C)): Declare longval and
7550 ulongval to be static, to avoid unwanted GCC warning. Problem
7551 reported by Michael Jennings via Daniel Reed; see
7552 <https://bugzilla.redhat.com/beta/show_bug.cgi?id=143852>.
7554 2005-01-05 Alexandre Duret-Lutz <adl@gnu.org>
7556 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Define datarootdir,
7557 docdir, htmldir, dvidir, pdfdir, psdir, and localdir. Update
7558 datadir, infodir, and mandir. Adjust argument parsing code.
7559 (_AC_INIT_HELP): Update help text.
7560 * doc/autoconf.texi (Installation Directory Variables): Document
7563 2005-01-04 Noah Misch <noah@cs.caltech.edu>
7565 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): If the Make program does
7566 not seem to work, assume it does set $(MAKE).

7569 2005-01-03 Stepan Kasal <kasal@ucw.cz>
7571 * lib/m4sugar/m4sh.m4 (AS_REQUIRE): Add a comment about nesting.
7573 2005-01-03 Stepan Kasal <kasal@ucw.cz>
7575 A cleanup of the diversion support in m4sugar.
7577 * lib/m4sugar/m4sugar.m4 (_m4_divert): A typo in description.
7578 (_m4_divert_n_stack): New macro; the expansion is
7579 <newline>m4_divert_stack, if m4_divert_stack is defined, and void
7581 (m4_divert, m4_divert_push, m4_divert_pop, m4_init): Use it.
7582 (m4_divert_push, m4_divert_pop, _m4_defun_epi): Don't expand the word

8058 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Have configure
8059 handle "--" as per POSIX. Suggested by Paul Pogonyshev.

8078 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C),
8079 AC_C_LONG_DOUBLE): Undo 2004-06-04 change, as it didn't work with
8080 HP-UX 11.23 cc/aCC or Tru64 4.0 cc. Problem reported by Noah Misch in
8081 <http://lists.gnu.org/archive/html/autoconf/2004-07/msg00004.html>.
8083 More fixes to support spaces in the name of the build directory.
8084 This isn't a complete fix but it's an improvement.
8086 * bin/autoconf.as (autom4te_options): New var.
8087 Use it instead of appending to AUTOM4TE, so that we can allow
8088 spaces in the build directory's absolute name.
8089 * bin/autoheader.in ($autoconf): Allow spaces in file names.

8143 useful for pkdsh, too.

8147 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Require
8148 _AS_UNSET_PREPARE, so that we can use $as_unset directly.
8149 Don't fail if ENV or BASH_ENV is readonly.
8150 (AS_SHELL_SANITIZE): Don't fail if ENV, MAIL, MAILPATH, LC_ALL,
8151 etc. are read only. Problem reported by Ludovic Courtes.
8153 2004-06-23 Noah Misch <noah@cs.caltech.edu>

8161 * doc/autoconf.texi (File System Conventions): Warn about
8162 names like "aux". Problem reported by Eric Blake.
8164 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY (C)): Use division
8165 by zero instead of array size, so that we can use any arithmetic
8166 constant expression (instead of requiring an integer constant
8167 expression). This allows us to test expressions like DBL_MAX <
8168 LDBL_MAX, which didn't conform to the C standard using the old
8170 (AC_C_LONG_DOUBLE): Put back in the tests for LDBL_MAX and LDBL_EPSILON,
8171 now that we can do floating-point tests at compile time.
8173 2004-06-02 Paul Eggert <eggert@cs.ucla.edu>
8175 * lib/autoconf/c.m4 (AC_C_LONG_DOUBLE): Don't check LDBL_MAX
8176 and LDBL_EPSILON, as the resulting expression isn't an
8177 integer constant expression and violates the C standard.
8178 Problem reported by Nelson H. F. Beebe. Also, check
8179 for "L" suffix, and check that long double doesn't have
8180 worse range or precision than double, that mixed-mode
8181 arithmetic doesn't generate a diagnostic, that double
8182 constants fit in long double.

8211 change). Patch reported by Ralf Wildenhues in
8212 <http://mail.gnu.org/archive/html/bug-autoconf/2004-05/msg00092.html>.
8214 * lib/autoconf/functions.m4 (AC_FUNC_MBRTOWC): Don't assume that a
8215 function F exists if the compiler and linker let you compile an
8216 expression like (F != 0). Recent versions of GCC optimize away
8217 the reference to F in that case, since every function address must
8218 be nonzero, so the link succeeds even if F does not exist.
8219 Problem reported by Manu in
8220 <http://mail.gnu.org/archive/html/bug-gnu-utils/2004-05/msg00060.html>.

8235 referencing AC_FUNC_STRERROR_R.
8237 * doc/autoconf.texi (Particular Functions): In AC_FUNC_CLOSEDIR_VOID,
8238 note pessimistic assumption when cross compiling.
8240 2004-05-16 Paul Eggert <eggert@cs.ucla.edu>
8242 * doc/autoconf.texi (Limitations of Make): Note that BSD make
8243 (until 2004) invoked subcommands with sh -e, contra POSIX.
8244 Reported by Kevin Ryde.
8246 2004-05-10 Eric Sunshine <sunshine@sunshineco.com>
8248 * programs.m4 (_AC_PROG_GREP): Fixed bug where PATH argument handed to
8249 _AC_PATH_PROG_FEATURE_CHECK contained leading whitespace (i.e.
8250 " $PATH:/usr/xpg4/bin"). This resulted in bogus tests, such as
8251 `test -f " /usr/bin/grep"', which _always_ failed.
8252 (AC_PROG_SED): Ditto bogus PATH fix.
8253 * autoconf.texi (AC_PROG_GREP): Properly document that this macro
8254 requires that grep correctly supports _multiple_ `-e' options, rather
8255 than stating only that grep should accept `-e'.
8257 2004-05-03 Paul Eggert <eggert@cs.ucla.edu>
8259 Port to C99, which requires that 'exit' be declared.
8261 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Use AC_INCLUDES_DEFAULT
8262 to ensure that stdlib.h is included.
8263 * lib/autoconf/functions.m4 (_AC_LIBOBJ_ALLOCA, AC_FUNC_SETPGRP,
8264 AC_FUNC_STRTOD, AC_FUNC_SETVBUF_REVERSED, AC_FUNC_FORK, _AC_FUNC_FORK,
8265 _AC_FUNC_VFORK, AC_FUNC_WAIT3): Likewise.
8266 * lib/autoconf/specific.m4 (AC_SYS_RESTARTABLE_SYSCALLS): Likewise.
8267 * lib/autoconf/types.m4 (AC_TYPE_GETGROUPS): Likewise.
8268 * lib/autoconf/headers.m4 (AC_HEADER_STDC): Include <stdlib.h>
8269 when using 'exit' in a test; C99 requires that 'exit' be declared.
8271 2004-05-02 Paul Eggert <eggert@cs.ucla.edu>
8273 * doc/autoconf.texi (Particular Programs): AC_PROG_GREP
8274 now prefers 'grep' implementations that accept -e.
8275 (Limitations of Usual Tools): Describe problems of traditional
8276 egrep and fgrep with long input lines, and of traditional grep
8278 * lib/autoconf/programs.m4 (AC_PROG_GREP): Check for -e, too.
8279 (_AC_PROG_GREP): Assume 3rd arg is properly quoted for the shell.
8280 All callers changed. Append /usr/xpg4/bin to the PATH, for
8282 (_AC_FEATURE_CHECK_LENGTH): Discard stderr, so we don't bother
8283 the user with complaints about multiple -e options.
8284 * tests/local.at (AC_STATE_SAVE): Use $GREP, not grep.
8285 Define it with AC_PROG_GREP.
8286 * configure.ac (AC_PROG_GREP): Add.
8287 * lib/freeze.mk (GREP): New macro.
8289 2004-05-02 Eric Sunshine <sunshine@sunshineco.com>
8291 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Consult $SHELL as
8292 a possible candidate only after all others fail, rather than
8293 consulting it first. This improves backward compatibility by
8294 better reflecting the way shell selection occurred in previous
8295 versions of Autoconf, and should help to avoid triggering latent
8296 problems in other packages, such as the one in Automake where zsh
8297 is not handled robustly:
8298 http://mail.gnu.org/archive/html/automake/2004-04/msg00095.html
8299 Although it is not Autoconf's responsibility to work around
8300 problems in Automake, it nevertheless makes sense to avoid
8301 introducing unnecessary incompatibilites.
8303 2004-04-22 Albert Chin-A-Young <china@thewrittenword.com>,
8304 Gary V. Vaughan <gary@gnu.org>
8306 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Don't guess
8307 how deeply nested we are when a suitable tool is found, set the
8308 ac_path_TOOL_found flag.
8309 (_AC_PATH_PROG_FEATURE_CHECK): Encapsulate knowledge of how deeply
8310 nested we are in this macro. Break out of all 3 nested loops if
8311 ac_path_TOOL_found is set.
8313 2004-04-21 Gary V. Vaughan <gary@gnu.org>
8315 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Break out
8316 of the _AS_PATH_WALK loop too if GNU flavor is found.
8318 2004-04-21 Alexandre Duret-Lutz <adl@gnu.org>
8320 * doc/autoconf.texi (Limitations of Make): Update documentation
8321 for `$<'. New entry `Long lines', based on a report from Simon
8322 Josefsson. Augment the documentation for SHELL = @SHELL@ with a
8323 paragraph about DJGPP, based on a mail from Richard Dawe.
8325 2004-04-20 Paul Eggert <eggert@twinsun.com>
8327 * tests/c.at (C keywords): Don't assume that GCC supports
8328 "restrict" and "inline", as sufficiently-old GCC versions do not
8329 (also, GCC configured to be in pedantic C89 mode does not).
8330 Problem reported by Sumit Pandya in:
8331 http://mail.gnu.org/archive/html/autoconf/2004-04/msg00092.html
8333 * lib/autoconf/c.m4 (_AC_PROG_CC_G, _AC_PROG_CXX_G): Don't
8334 consider -g to work if it generates warnings when plain compiles
8335 don't. Problem reported by Braden McDaniel in:
8336 http://mail.gnu.org/archive/html/autoconf-patches/2003-07/msg00014.html

8342 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Remove potential
8343 linker output files before linking, to work around IRIX 6 linker bug.
8344 Problem reported by Rainer Orth in:
8345 http://mail.gnu.org/archive/html/autoconf-patches/2004-02/msg00007.html
8347 2004-04-20 Gary V. Vaughan <gary@gnu.org>
8349 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Make the
8350 best tool so far counter rely on the tool path variable name to
8351 avoid checks for one tool being affected by the results of running
8352 the length check on a previous tool.
8354 * lib/autoconf/programs.m4 (_AC_PROG_GREP): Take an additional
8355 match expression argument, as different greps have different
8356 regular expression flavours.
8357 (AC_PROG_FGREP): Pass 'FGREP'. fgrep treats all match chars as
8359 (AC_PROG_EGREP): Pass 'EGREP$'.
8360 (AC_PROG_GREP): Pass 'GREP$'.
8362 2004-04-20 Albert Chin-A-Young <china@thewrittenword.com>
8364 * lib/autoconf/programs.m4 (AC_PROG_GREP): Cache variable
8365 is `ac_cv_path_GREP', not `oc_cv_path_GREP'.
8367 2004-03-29 Paul Eggert <eggert@twinsun.com>
8369 * doc/autoconf.texi (Particular Headers, Particular Types, Generic
8370 Types, Specific Compiler Characteristics, System Services,
8371 Obsolete Macros): Use 'long int', 'short int', 'unsigned int'
8372 etc. consistently instead of 'long', 'short', 'unsigned' etc.
8373 * lib/autoconf/c.m4 (AC_LANG_INT_SAVE(C), AC_C_BIGENDIAN): Likewise.
8374 * lib/autoconf/functions.m4 (AC_FUNC_MMAP, AC_FUNC_SELECT_ARGTYPES):

8385 2004-03-28 Paul Eggert <eggert@twinsun.com>
8387 * doc/autoconf.texi (Particular Structures): AC_STRUCT_TIMEZONE
8388 now defines HAVE_DECL_TZNAME if it is declared, when
8389 HAVE_STRUCT_TM_TM_ZONE is not defined.
8390 * lib/autoconf/types.m4 (AC_STRUCT_TIMEZONE): Implement this.
8391 Do not assume atoi. Rely on HAVE_DECL_TZNAME when testing

8400 2004-03-26 Steven G. Johnson <stevenj@alum.mit.edu>
8402 * lib/autoconf/fortran.m4 (_AC_PROG_FC): new name of Intel
8403 Fortran compiler is ifort, also added pghpf; thanks to Nelson
8404 H. F. Beebe for the bug report.
8406 2004-03-26 Steven G. Johnson <stevenj@fftw.org>
8408 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): fix for
8409 quoted -cmdline argument in Portland Group compiler (bug
8410 reported by Jeffrey J. Barteet).
8412 2004-03-25 Kevin Ryde <user42@zip.com.au>

8458 2004-03-03 Paul Eggert <eggert@twinsun.com>
8460 * bin/Makefile.am (edit): Don't use $< in a context where
8461 POSIX doesn't require support for it. Use $@.in instead.
8462 Problem reported by Anthony N. Frasso in
8463 <http://mail.gnu.org/archive/html/autoconf/2004-03/msg00008.html>.

8472 2004-02-20 Alexandre Duret-Lutz <adl@gnu.org>
8474 * doc/autoconf.texi (Limitations of Usual Tools) <mkdir>: `mkdir -p'
8475 is not always thread-safe. Report from Nathanael Nerode.
8477 2004-02-18 Paul Eggert <eggert@twinsun.com>
8479 Fix a dependencies problem, stemming from a Autoconf 2.59 build
8480 problem on QNX reported by Stephen Rasku in

8492 AC_SUBST provides no portable way to escape literal newlines.
8494 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS): Ignore all
8495 flags of the form -lcrt*.o, not just -lcrt[01].o and -lcrtbegin.o.
8496 Darwin uses -lcrt2.o and there's little point to cataloging all
8497 the system variants. Partial fix reported by Andreas Waechter in:

8522 Eric Sunshine <sunshine@sunshineco.com>
8523 Paul Eggert <eggert@twinsun.com>
8525 * lib/m4sugar/m4sh.m4 (M4SH-SANITIZE): New diversion.

8573 * lib/autoconf/general.m4 (_AC_INIT_COPYRIGHT): Add 1992 thorugh
8574 2003 (except 1997) to the list of copyright years. This undoes
8575 the 2003-05-22 change, which removed the older years from the list.
8576 * lib/autoconf/status.m4 (AC_OUTPUT): Update copyright date to 2004.

8589 _AC_PROG_GREP, and AC_PROG_SED.

8622 * doc/autoconf.texi (Default Includes): Include <stdint.h> even if
8623 HAVE_INTTYPES_H is defined. This is needed on Tru64 5.1b with
8624 Compac C V6.5-207 (dtk), which defines uintmax_t in <stdint.h> but
8625 not <inttypes.h>. Problem reported by Tim Mooney in
8626 <http://mail.gnu.org/archive/html/bug-coreutils/2004-01/msg00147.html>.
8627 * lib/autoconf/headers.m4 (_AC_INCLUDES_DEFAULT_REQUIREMENTS):
8630 * lib/autoconf/programs.m4 (AC_PROG_SED): Use diff, not sed;
8631 otherwise "make check" fails because it forbids cmp (I guess
8632 because cmp treats files as binary on DOS-like systems).

8635 have changed in 2004.

8647 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Try -std, not -std1, since
8648 -std1 disables some useful extensions on Tru64. Problem reported

8652 2004-01-14 Paul Eggert <eggert@twinsun.com>
8654 * doc/autoconf.texi (Programming in M4sh): Document that
8655 AS_MKDIR_P succeeds if the destination is a symbolic link
8656 to an existing directory.
8657 (Limitations of Usual Tools): Note that mkdir -p might not
8658 succeed on symlinks to directories.
8660 2004-01-13 Paul Hilfinger <hilfinger@CS.Berkeley.EDU>
8662 * lib/autoconf/autoupdate.m4 (AU_DEFUN): Grammar fix in comment.

8672 2004-01-10 Jim Meyering <jim@meyering.net>
8674 * doc/autoconf.texi (Running the Preprocessor): Correct grammar.
8676 2004-01-09 Paul Eggert <eggert@twinsun.com>
8678 * lib/autoconf/general.m4: Fix bug: AC_CHECK_SIZEOF evokes a warning
8679 with `autoconf -Wall,error'. Bug reported by Eric Blake in:
8680 http://mail.gnu.org/archive/html/autoconf-patches/2004-01/msg00000.html
8681 (_AC_COMPUTE_INT_COMPILE): Invoke _AC_COMPILE_IFELSE, not
8682 AC_COMPILE_IFELSE, since we now assume our caller invokes
8683 AC_LANG_COMPILER_REQUIRE, for symmetry with _AC_COMPUTE_INT_RUN.
8684 (_AC_COMPUTE_INT_RUN): Likewise, for _AC_RUN_IFELSE instead
8685 of AC_RUN_IFELSE; this avoids the warning mentioned above.
8686 (_AC_COMPUTE_INT): Invoke AC_LANG_COMPILER_REQUIRE.
8688 2004-01-07 Paul Eggert <eggert@twinsun.com>
8690 * lib/autoconf/general.m4 (_AC_LIBOBJS_NORMALIZE): Avoid \$ inside
8691 `"'...'"`, as it's confusing (and I suspect it may not work on
8692 some platforms). The code was incorrect anyway, as it assumed
8693 that \$ evaluated to itself in that context. Reported by
8694 Alexandre Duret-Lutz.
8696 2004-01-07 Alexandre Duret-Lutz <adl@gnu.org>
8698 * lib/autom4te.in (Automake-preselections): Preselect AC_LIBTOOL_TAGS

8731 * Makefile.am (autom4te-update):
8732 Replace "rm -rf" and "rm -fr" with "rm -f -r", as POSIX requires.

8748 * doc/autoconf.texi (Limitations of Usual Tools): Mention that cc
8749 -c -o might not work. From a suggestion by Kevin Ryde.
8750 (C Compiler, Generating Sources, Limitations
8751 of Usual Tools, Limitations of Make, Making testsuite Scripts):

8764 2003-12-27 Alexandre Duret-Lutz <adl@gnu.org>
8766 * doc/autoconf.texi (Limitations of Make) <Automatic rule rewriting>:
8767 Documents OSF1/Tru64 make behavior. Replace `VPATH = ../src' by
8768 `VPATH = ../pkg/src' in examples to make the OSF1/Tru64 make
8769 explanation clearer.

8780 * tests/atlocal.in: Store the result here.
8781 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Extracted from

9050 Problems reported by Eric Sunshine.
9052 2003-10-08 Steven G. Johnson <stevenj@alum.mit.edu>
9054 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Omit quoted
9055 -mGLOB_options_string stuff for Intel ifc, which can cause
9056 _AC_FC_LIBRARY_LDFLAGS to fail. Use (faster) case for
9057 pattern-matching instead of grep.

9077 2003-10-04 Steven G. Johnson <stevenj@ab-initio.mit.edu>
9079 * lib/autoconf/fortran.m4 (_AC_PROG_FC_G): Use language-specific
9080 cache variable instead of $G77 to decide whether to include -O2,
9081 since $G77 is specific to Fortran 77.
9083 2003-10-03 Steven G. Johnson <stevenj@alum.mit.edu>
9085 * lib/autoconf/fortran.m4 (AC_FC_FREEFORM): Support Absoft "-f
9086 free" flag. Re-order flags tested into rough order of popularity.
9088 2003-10-03 Steven G. Johnson <stevenj@alum.mit.edu>
9090 * lib/autoconf/fortran.m4 (AC_PROG_FC): Reverse the order of the
9091 arguments so that it can be used with syntax identical to
9092 AC_PROG_F77, and so that we can more easily decide to
9093 remove/deprecate the DIALECT optional argument in the future if it

9096 non-freeform-supporting compilers. Document freeform flags.

9160 <http://mail.gnu.org/archive/html/autoconf/2003-07/msg00042.html>.
9161 (_AS_MKDIR_P_PREPARE): Change "rm -fr ./-p" to the more-conservative
9162 "test -d ./-p && rmdir ./-p". Suggested by Andreas Schwab in:

9167 * lib/autoconf/status.m4 (_AC_OUTPUT_COMMANDS): Make sure the
9168 directory for AC_CONFIG_COMMANDS' first argument exists.
9169 This makes valid the invocation of _AC_SRCPATH that follows.
9170 Reported by Eric Sunshine.
9171 * doc/autoconf.texi (Configuration Commands): Adjust.
9173 2003-09-26 Akim Demaille <akim@epita.fr>

9194 The test suite are sometimes assigning timings incorrectly.
9195 Reported by Henk Krus.
9196 Diagnosed by Nicolas Joly.
9198 * lib/autotest/general.m4 (AT_CLEANUP): Rename AT_help as
9200 Instead of making AT_help a sequence of assignments to grow
9201 $at_help_all, just make AT_help_all be the growing contents of
9202 $at_help_all, and make a single assignment in...
9204 (at_times_skip): Flip the meaning and rename as...
9206 (AT_INIT): When summarizing the test that ran, remove
9207 $at_times_file after use, and check it is present before trying to

9214 * bin/Makefile.am (edit): Handle '@configure_input@'.
9215 (autoconf, autoheader, autom4te, autoreconf, autoscan, autoupdate)
9216 (ifnames): chmod -w.
9217 * tests/wrapper.as (AUTOCONF, AUTOM4TE, ): Point to tests/
9218 executables, not bin/ executables! Otherwise all the magic needed
9219 to find non installed files is turned off. This caused a failure
9220 of test 40 and 41 that ran aclocal 1.8 which in turn ran autom4te
9221 as found in its environment (sent by tests/autoreconf): pointing
9222 to bin/autom4te that could not find its files.
9223 * tests/mktests.sh: Force the replacement of generated files, for
9224 the sake of "mv" program that are interactive when overwriting a

9317 * tests/mktests.sh (ac_exclude_list): Add AC_FC_FUNC.
9319 2003-09-02 Steven G. Johnson <stevenj@alum.mit.edu>
9321 Add support for newer Fortran dialects. The F77 interface is
9322 unchanged, and continues to support Fortran 77. New FC macros
9323 correspond to all the old F77 macros, with output variables FC,
9324 FCFLAGS, and FCLIBS. AC_PROG_FC defaults to picking the newest
9325 available dialect, but older dialects can be specified. There are
9326 new macros AC_FC_SRCEXT to set the source extension, and
9327 AC_FC_FREEFORM to accept free-form source files.

9365 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): Don't m4_default the arguments that
9366 are defaulted by AT_CHECK anyway.
9367 Use AT_CHECK_AUTOM4TE.

9443 Use &verb, not &verbose.
9445 2003-08-21 Akim Demaille <akim@epita.fr>
9447 * bin/autoheader.in (&parse_args): Use &parse_warnings and
9449 ($help): Use Autom4te::ChannelDefs::usage.
9450 * bin/autoscan.in: Use Autom4te::ChannelDefs.
9451 * lib/Autom4te/General.pm: Don't export error: you don't own it.
9453 2003-08-21 Akim Demaille <akim@epita.fr>
9455 First stab at preserving warnings between calls to autom4te,
9456 including when the cache is used.
9458 There are still several issues: (i) there are too many runs of m4
9459 (one for include, one for warnings, and some more), (ii) warnings
9460 spreading on several lines are not handled gracefully, (iii) the
9461 code meant to have the call stack display for errors does not work
9462 (its handling should move from m4 to autom4te).
9464 * bin/autom4te.in Autom4te::Channels, Autom4te::ChannelDefs):
9466 (@preselect): Add m4_warn.
9467 ($exit_status): Remove, use $exit_code.
9468 ($help): Use Autom4te::ChannelDefs::usage.
9469 (&handle_m4): No longer define the m4_warnings.
9470 At each run, extract and report the warnings.
9471 Always cache the result, including if the exit status is on
9472 failure, since if nothing changes, we should result in the same
9473 failure, hence we can use the cache.
9474 * lib/m4sugar/m4sugar.m4 (m4_warning_ifelse, _m4_warning_ifelse)
9475 (_m4_warning_error_ifelse, __m4_warning_error_ifelse, _m4_warn):
9477 (m4_warn): Redefine as a do-nothing: it is its invocation that
9478 matters, as warnings are now reported via traces.
9479 * lib/autoconf/general.m4 (AC_DIAGNOSE): Don't make it a copy of
9480 the contents of m4_warn: make it _call_ m4_warn, so that tracing
9481 the latter reveals calls to the former.
9485 * tests/m4sugar.at (m4@&t@_warn): Use existing warning categories.

9520 In particular, be Autoconf tools are really silent when properly

9642 From Gareth McCaughan.
9644 2003-06-23 Akim Demaille <akim@epita.fr>
9646 * lib/autotest/general.m4 (AT_INIT): Report a single config.log,
9647 not all of them. This fixes 1. the fact that when testing
9648 Autoconf there are many many config.log, 2. the incorrect use of
9649 top_srcdir to find config.log.
9650 Don't mix the detailed output of failed test with the summary of
9651 failures. Rather, append detailed log afterwards.
9653 2003-06-23 Akim Demaille <akim@epita.fr>

9738 2003-05-23 Alexandre Duret-Lutz <adl@gnu.org>
9740 * lib/Autom4te/General.pm (END): Rewrite exit code processing.
9741 Do not call `_exit()', simply modify `$?'.
9742 (xsystem): Reset $! before running system, and check it afterward.
9743 * tests/tools.at (autoupdating AC_PREREQ): Expect exit status
9744 63 for version mismatches.
9746 2003-05-23 Akim Demaille <akim@epita.fr>
9748 * lib/autoconf/status.m4: Prefer "TAB-SP" to "SP-TAB", because of
9749 Emacs' dangerous whitespace.el behavior (smashing "useless" spaces in
9750 the middle of a line).
9751 * lib/m4sugar/m4sugar.m4: Likewise.
9752 Remove useless spaces in comments.

9768 Paul Eggert <eggert@twinsun.com>
9770 * lib/autoconf/c.m4 (_AC_PROG_CXX_EXIT_DECLARATION):
9771 Remove `#include <stdlib.h>' from the list; we should never
9772 make confdefs.h include <stdlib.h> or <cstdlib>, because the
9773 resulting namespace pollution would cause other tests to fail.
9774 Configure scripts run with some older versions of g++ and HP's
9775 aCC would fail due to such an #include. Problems reported by
9776 Matthew Mueller in <http://bugs.debian.org/120704> and by
9778 <http://mail.gnu.org/archive/html/autoconf/2003-05/msg00063.html>.
9779 In the test, use the test declaration before including <stdlib.h>,
9780 as that's closer to how it'll be used.
9782 2003-05-23 Akim Demaille <akim@epita.fr>
9784 * doc/autoconf.texi (Header Portability): ucred.h.
9787 2003-05-22 Paolo Bonzini <bonzini@gnu.org>
9789 Overhaul Autotest's logging: generate separate log files
9790 in testsuite.dir/NNN/testsuite.log, and append them to
9791 testsuite.log instead of re-running the test verbosely.
9793 * lib/autotest/general.m4 (AT_INIT): Use a single redirected
9794 file descriptor, write 0 to at_status_file instead of setting
9795 at_status=0, initialize some new variables (at_status_file,
9796 at_group_log, at_suite_log, at_tee_pipe). Remove the cruft
9797 to rerun the tests, instead append the at_group_log to the
9798 at_suite_log when a test fails.
9799 (AT_SETUP): pipe the test case's output into at_tee_pipe,
9800 with the AS_MESSAGE_LOG_FD redirected to stdout.
9801 (AT_CLEANUP): save the output status in $at_status_file
9802 and restore it, redirect the AS_MESSAGE_LOG_FD back to
9804 (AT_CHECK): since tests are run with a redirected stdout,
9805 and used to be re-run in verbose mode, turn some $at_verbose
9806 into echo, and don't redirect the output of testing stdout
9809 * lib/autotest/autoconf.texi (testsuite Scripts): Update
9810 the name of the debugging directory and information about

9925 2003-05-07 Alexandre Duret-Lutz <adl@gnu.org>
9927 * lib/Autom4te/XFile.pm (lock, truncate): Do not pass @_ to flock
9930 2003-05-06 Akim Demaille <akim@epita.fr>
9932 Don't try to be smart with aclocal 1.8+ because (i) aclocal no
9933 longer updates aclocal.m4 if useless, (ii) if a file m4_included
9934 by aclocal.m4 is changed it might require the importing of another
9935 m4 extension file, i.e., aclocal must be run.
9937 * bin/autoreconf.in (&run_aclocal, $aclocal_supports_force): New.
9938 (&parse_args): Use --force with aclocal if required and supported.

9952 2003-04-29 Derek Price <derek@ximbiot.com>
9954 * lib/autotest/general.m4 (AT_KEYWORDS): Don't use a comma as the
9955 seperator with m4_append_uniq(). It doesn't work.
9956 (AT_CLEANUP): Add `;' to end of at_help_all.
9957 (AT_INIT): Allow --keywords to be specified more than once. When

9966 entries on one line, for brevity and to make it easier for me to

10034 header causes problems.
10036 2003-03-28 Akim Demaille <akim@epita.fr>
10038 * tests/torture.at (Configuring subdirectories): Require aclocal
10039 1.4, otherwise the test fails, as it does support configure.ac.

10062 * lib/autoconf/general.m4 (AC_ARG_VAR): Use AS_HELP_STRING instead of
10063 obsolete AC_HELP_STRING.
10064 (AC_HELP_STRING): AU_DEFUN to...
10065 * lib/m4sugar/m4sh.m4 (AS_HELP_STRING): ...here.
10066 * tests/m4sh.at (AS_HELP_STRING): New test.

10070 2003-03-26 Derek Price <derek@ximbiot.com>
10072 * lib/autotest/general.m4: s/DEFAULT/DEFAULTS/ since it makes more
10073 sense. Verbosify the diversion definitions comment.

10113 (Automake): Automake 1.5+ no longer requires special tools to be
10114 present on the developer's host.
10116 2003-02-26 Richard Dawe <rich@phekda.freeserve.co.uk>
10118 * bin/autoheader.in (BEGIN): For DJGPP SHELL may not be set
10119 to a shell that can handle redirection or quoting correctly.

10124 * bin/autoscan.in (BEGIN): Likewise.
10125 * bin/autoupdate.in (BEGIN): Likewise.
10126 * bin/ifnames.in (BEGIN): Likewise.
10128 * bin/ifnames.in: Add final newline to help and version messages.
10130 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Translate colons,
10131 to cope with DOS-style absolute paths, when constructing
10134 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS, _AC_OUTPUT_FILES):
10135 When constructing paths with IFS=:, quote the path. If we're
10136 constructing a DOS-style absolute path, we don't want to split it
10139 * tests/atspecific.m4 (AT_CHECK_CONFIGURE): Fix typo
10142 2003-02-25 Pavel Roskin <proski@gnu.org>

10150 2002-09-01 patch by replacing "test -n" with "test -z".
10151 This fixes a bug found by Jeff Painter and reported by Tom Epperly in
10152 <http://mail.gnu.org/archive/html/autoconf/2003-02/msg00139.html>.
10154 * doc/autoconf.texi (Shell Substitutions): test -n -> test -z,
10155 to fix a mismatch between example and discussion.
10157 2003-02-24 Kevin Ryde <user42@zip.com.au>
10159 * doc/autoconf.texi (Limitations of Builtins): Add notes on printf
10160 format starting with "-".
10162 2003-02-20 Alexandre Duret-Lutz <adl@gnu.org>
10164 * doc/autoconf.texi (Limitations of Make): `foo=bar make -e'
10165 is not portable inside Makefile.
10167 2003-02-20 Akim Demaille <akim@epita.fr>
10169 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): When
10170 compiler says yeah, but preproc says nope, compiler is right.
10171 Conversely, prompt the reader to send a bug report to the
10172 maintainers of the package, not of Autoconf.
10174 2003-02-20 Klee Dienes <kdienes@apple.com>
10176 * bin/autoreconf.in (autoreconf_current_directory): Properly
10177 handle an empty aclocal.m4.

10182 $ac_prefix_program.
10185 2002-12-23 Paul Eggert <eggert@twinsun.com>
10187 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Define $1 to an
10188 innocuous variant befor including <limits.h> or <assert.h>. This
10189 works around a bug reported by Albert Chin: HP-UX 11i
10190 (and earlier versions) have a <limits.h> that declares
10191 gettimeofday and many other functions.
10193 2002-12-03 Paul Eggert <eggert@twinsun.com>
10197 * NEWS, configure.ac: Update version.
10199 * doc/fdl.texi: Upgrade to FDL version 1.2.
10201 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Use the function f
10202 nontrivially in main's body, so that f's external declaration is
10203 not optimized away in AIX. This should fix the bug reported by
10205 <http://mail.gnu.org/pipermail/autoconf/2002-November/014508.html>.
10207 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C),
10208 _AC_PROG_PREPROC_WORKS_IFELSE): Use <limits.h> if __STDC__ is
10209 defined, to support freestanding compilers. This should fix the
10210 bug reported by Momchil Velkov in
10211 <http://mail.gnu.org/pipermail/autoconf/2002-November/014490.html>.
10213 * doc/autoconf.texi (Obsolete Macros): Fix typos (insert empty
10214 arg, AC_DEFINE -> AC_DEFINE_UNQUOTED) in documentation for

10217 <http://mail.gnu.org/pipermail/autoconf-patches/2002-December/008830.html>.
10219 * Makefile.maint (www-gnu): New macro.
10220 (standards.texi-url_prefix, make-stds.texi-url_prefix): Use it, as

10226 \(.*\) match is too long and there is something more to be checked.
10227 <http://mail.gnu.org/pipermail/autoconf/2002-November/014524.html>

10245 Update from masters.
10247 2002-11-14 Akim Demaille <akim@epita.fr>
10249 * Makefile.maint: Sync with Bison, i.e.:
10250 (po-check): Scan .l and .y files instead of the
10251 .c and the .h files that they generate. This fixes the bug
10252 reported by Tim Van Holder in:
10253 <http://mail.gnu.org/pipermail/bison-patches/2002-November/001352.html>
10254 Look for N_ as well as for _. Try to avoid matching #define for
10258 2002-11-14 Akim Demaille <akim@epita.fr>
10260 * doc/autoconf.texi (C Compiler): Compiling several files at once.
10261 From Paul Eggert and Albert Chin-A-Young.
10263 2002-11-14 Akim Demaille <akim@epita.fr>
10265 * doc/autoconf.texi (C Compiler): Solitary backslashes.
10266 From Paul Eggert and Albert Chin-A-Young.
10268 2002-11-14 Kevin Ryde <user42@zip.com.au>
10270 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Initialize f=$1 rather
10271 than assigning in main, to avoid HP cc +O3 optimizing it away.
10273 2002-11-12 Peter Eisentraut <peter_e@gmx.net>
10275 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Add -q
10276 option. Process --recheck after parsing all options. Pass -q
10277 option to configure on --recheck.
10278 (AC_OUTPUT): Pass -q from configure to config.status.
10279 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Strip -q from
10280 arguments to record.
10281 * doc/autoconf.texi (config.status Invocation): Document
10282 config.status -q option.
10284 2002-11-07 Alexandre Duret-Lutz <adl@gnu.org>
10286 * bin/autoscan.in (scan_file): Scan Makefile.am too. Ignore
10287 Makefile.in if Makefile.am exists.
10288 (output): Strip `.am' from Makefiles. Don't
10289 output AC_CONFIG_FILES if no Makefiles were found.

10309 Reported by Ezra Peisach.
10311 2002-11-05 Akim Demaille <akim@epita.fr>
10313 * lib/autoconf/autoheader.m4 (_AH_TEMPLATE_OLD, _AH_VERBATIM_OLD):
10315 We _have_ to stop using the old compatibility scheme that tried to
10316 avoid useless backslashes because Libtool 1.4.3 contains a
10317 AC_DEFINE([error_t], [int],
10318 [Define to a type to use for \`error_t' if it is not
10319 otherwise available.])
10320 We _have_ to quote the single quote and backslashes with \. The
10321 old compatibility scheme saw that ` was backslashed, and therefore
10322 did not quote the single quote. Hence before this patch, Autoconf
10323 was not compatible with Libtool.
10325 2002-11-04 Paul Eggert <eggert@twinsun.com>
10327 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Set the following variables,

10344 (&autoreconf): here.
10345 ($help, $make, &parse_args, &autoreconf_current_directory):
10347 * doc/autoconf.texi (autoreconf Invocation): Adjust.
10349 2002-10-31 Bruno Haible <bruno@clisp.org>

10365 2002-10-31 Akim Demaille <akim@epita.fr>
10367 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Use and display
10368 `$(MAKE)' instead of '${MAKE}' to emphasize that we refer to the
10369 Make variable, not a shell variable.
10370 Suggested by Bruno Haible.
10372 2002-10-31 Akim Demaille <akim@epita.fr>
10374 * bin/autom4te.in (load_configuration): Reject #args out of any
10377 2002-10-31 Akim Demaille <akim@epita.fr>
10379 * lib/autoconf/general.m4 (_AC_MSG_LOG_CONFTEST): New.
10380 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE, _AC_LINK_IFELSE)

10382 * lib/autoconf/lang.m4 (_AC_COMPILER_OBJEXT):

10393 2002-10-29 Paul Eggert <eggert@twinsun.com>
10395 * doc/autoconf.texi (Particular Functions): AC_FUNC_MALLOC and
10396 AC_FUNC_REALLOC check for compatibility with glibc, not POSIX.
10397 Problem reported by Bruno Haible.
10399 2002-10-29 Akim Demaille <akim@epita.fr>
10401 * doc/autoconf.texi (Header Templates): Put also in words what the
10402 pictures says to assist free style readers.
10403 (Customizing autom4te): s/--cache=/--cache /.
10405 2002-10-29 Akim Demaille <akim@epita.fr>
10407 * lib/autoconf/functions.m4 (_AC_FUNC_VFORK): Include stdlib.h and
10409 sparc_address_test returns void.
10410 Use it with an argument, as prototyped.
10413 2002-10-29 Akim Demaille <akim@epita.fr>

10714 Reported by Alexandre Duret-Lutz.
10716 * bin/autom4te.in (&parse_args): Do not prepend `--reload-state'

10777 * bin/autoreconf.in (&autoreconf): Run autopoint before the first
10778 aclocal invocation, as Gettext macros might not be visible to

10781 traces) for AM_GNU_GETTEXT_VERSION uses, as autopoint does.
10782 Reported by Paul D. Smith.
10784 2002-10-08 Paul Eggert <eggert@twinsun.com>

10814 * tests/torture.at (Configuring subdirectories): Be robust to

10989 2002-09-12 Akim Demaille <akim@epita.fr>
10991 * bin/autoscan.in (&parse_args): Pass a reference to the lists, not

10996 * doc/autoconf.texi (Defining Symbols): Present two different
10997 prototypes for AC_DEFINE and AC_DEFINE_UNQUOTED to emphasize the
10998 difference between 1 argument calls, and 2-3 argument calls.
11000 2002-09-12 Peter Eisentraut <peter_e@gmx.net>
11002 * doc/autoconf.texi: Review grammar and punctuation.

11006 * doc/autoconf.texi: Fix minor formatting, spelling, and
11008 (Defining Symbols): Explain that AC_DEFINE(var) defaults to 1, but
11009 AC_DEFINE(var,,description) does not; and the AC_DEFINE(var) case
11012 2002-09-11 Akim Demaille <akim@epita.fr>
11014 * doc/autoconf.texi (Questions): Rename as...
11016 (Defining Directories): New.
11018 2002-09-09 Akim Demaille <akim@epita.fr>
11020 * doc/autoconf.texi (Making testsuite Scripts): Update.
11021 Suggested by Nishio Futoshi.
11023 2002-09-09 Koji Arai <JCA02266@nifty.ne.jp>
11025 * doc/autoconf.texi (Making testsuite Scripts): Use `@@' where a
11026 plain `@' is wanted.
11028 2002-09-09 Akim Demaille <akim@epita.fr>
11030 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Keep the
11031 `duplicates', since the algorithm was too naive and could keep
11032 `--prefix=1 --prefix=2 --prefix=1' as `--prefix=1 --prefix=2', and
11033 keep `--prefix foo --prefix bar' as `--prefix foo bar'.
11034 Reported by Ralf Corsepius.
11035 * tests/torture.at (Configuring subdirectories): Exercise these
11038 2002-09-09 Akim Demaille <akim@epita.fr>
11040 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Use $srcdir when
11041 looking for a replacement file.
11042 * lib/autoconf/general.m4 (AC_CHECK_DECLS): Check that the
11043 directory is relative.
11044 * doc/autoconf.texi (Generic Functions): Clarify the replacement
11045 directory definition.
11046 Reported by Andreas Schwab and Jim Meyering.
11048 2002-09-06 Akim Demaille <akim@epita.fr>
11050 * doc/autoconf.texi (Setting Output Variables): Clarify what
11051 precious variables are.
11052 Suggested by Pontus Skoeld.
11054 2002-09-05 Akim Demaille <akim@epita.fr>
11056 * bin/Makefile.am (autoconf, autoheader, autoreconf, autoupdate)
11057 (ifnames, autoscan, autom4te): Since we don't only depend on
11058 configure.ac variables (such as VERSION etc.), but also on prefix
11059 and so forth, depend on Makefile, not configure.ac.
11060 Reported by Alexandre Duret-Lutz.
11061 * doc/autoconf.texi (Installation Directory Variables): Adjust.
11063 2002-09-05 Kevin Ryde <user42@zip.com.au>
11065 * doc/autoconf.texi (Limitations of Make): HP-UX trailing backslashes
11066 doesn't seem to be confined to ia64, just say "some versions".
11068 2002-09-04 Akim Demaille <akim@epita.fr>
11070 * Makefile.am, doc/Makefile.am: Remove pdf targets, handled by
11072 * Makefile.am (maintainer-clean-local): Remove.
11073 (MAINTAINERCLEANFILES): Remove COPYING.
11075 2002-09-03 Paul Eggert <eggert@twinsun.com>
11077 * doc/autoconf.texi (Configuration Commands): Remove obsolete
11078 example for AC_CONFIG_COMMANDS_PRE. Problem reported by Marcus
11081 2002-09-03 Akim Demaille <akim@epita.fr>
11083 * configure.ac: Bump to 2.53d.
11084 * Makefile.am (AUTOMAKE_OPTIONS): Require 1.6c, i.e., CVS Automake
11085 as of today, on Automake's team suggestion.
11087 2002-09-03 Akim Demaille <akim@epita.fr>
11091 2002-09-02 Akim Demaille <akim@epita.fr>
11093 * bin/autom4te.in (parse_args): Don't honor AUTOM4TE_PATH and
11095 * configure.ac: Disable SITE_MACRO_DIR.
11097 2002-09-02 Jim Meyering <meyering@lucent.com>
11099 * doc/autoconf.texi (AC_SYS_POSIX_TERMIOS): Reflect renaming: s/am/ac/,
11100 i.e., change am_cv_sys_posix_termios to ac_cv_sys_posix_termios.
11101 Also, tweak grammar: s/make sure to/be sure to/.
11103 2002-09-02 Paul Eggert <eggert@twinsun.com>
11105 * doc/autoconf.texi (Limitations of Builtins): Explain why logical
11106 directory names are generally preferable to physical names.
11108 2002-09-02 Akim Demaille <akim@epita.fr>
11110 * lib/Autom4te/General.pm (&update_file): s/die/error/.
11111 Reported by Raja R. Harinath.
11112 * bin/autoheader.in, bin/autoreconf.in, bin/autoscan.in,
11113 * bin/autoupdate.in: Use error instead of die.
11115 2002-09-01 Paul Eggert <eggert@twinsun.com>
11117 * tests/mktests.sh (ac_exclude_egrep, au_exclude_egrep): Use
11118 ordinary shell concatenation rather than echo+tr+sed command that
11119 runs afoul of a long-line-related sed bug in Solaris 8.
11121 * bin/autoheader.in (parse_args): --warning -> --warnings.
11123 * bin/autoconf.as: Work even if "ls" outputs "FOO not found" to
11124 stdout, as traditional "ls" does.
11125 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT,
11126 _AC_COMPILER_EXEEXT_O): Likewise.
11127 * doc/autoconf.texi (Limitations of Usual Tools): Add "ls".
11129 * bin/autoconf.as: Add --prepend-include option. This patch was
11130 applied to bin/autoconf.in in the 2002-07-17 patch by Mark D. Roth,
11131 but bin/autoconf.in is generated automatically from bin/autoconf.as.
11133 * bin/autoconf.in, configure: Regenerate.
11135 * doc/autoconf.texi (Special Shell Variables): Mention
11136 ENV, MAIL, MAILPATH, PS1, PS2, PS4. Index PWD.
11138 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Unset ENV, MAIL,
11139 MAILPATH and set PS1, PS2, PS4 to default values, to work
11140 around bug in pre-3.0 UWIN ksh reported by Bruce Lilly.
11141 For LC_ALL etc, first try to set to "C" as POSIX requires and as
11142 the Autoconf documentation specifies; fall back to "unset" only if
11143 this fails. Use a shell for-loop for this rather than an m4 loop,
11144 to shorten the output script.
11146 2002-08-30 Paul Eggert <eggert@twinsun.com>
11148 * doc/autoconf.texi (Special Shell Variables): Mention POSIX
11149 1003.1-2001's requirements for CDPATH. Give a simpler workaround
11150 for the CDPATH problem. Document PWD.
11151 (Limitations of Builtins): Document the problem that "cd $foo" and
11152 "ls $foo" may refer to different directories in shells conforming
11153 to POSIX 1003.1-2001. Use PS1 rather than CDPATH for "unset"
11154 example, since the old example is now out of date.
11156 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Reject FOO if "cd
11157 FOO" and "ls FOO" talk about different directories; this catches
11158 problems when POSIX 1003.1-2001 "cd" fails due to symlink
11161 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Use AS_UNSET instead
11162 of rolling our own unset.
11163 (_AS_PREPARE): $as_unset CDPATH instead of AS_UNSETting it, since
11164 in practice we needn't worry about CDPATH if unset doesn't work.
11166 * Makefile.in, aclocal.m4, bin/Makefile.in,
11167 config/Makefile.in, doc/Makefile.in, lib/Makefile.in,
11168 lib/Autom4te/Makefile.in, lib/autoconf/Makefile.in,
11169 lib/autoscan/Makefile.in, lib/autotest/Makefile.in,
11170 lib/emacs/Makefile.in, lib/m4sugar/Makefile.in, man/Makefile.in,
11171 tests/Makefile.in: Regenerate with Automake 1.6.3.
11173 * config/config.guess, config/config.sub, config/mkinstalldirs:
11176 * configure: Regenerate with self.
11178 2002-08-30 Kevin Ryde <user42@zip.com.au>

11188 2002-08-29 Akim Demaille <akim@epita.fr>
11190 * lib/Autom4te/General.pm (&xqx): New.
11191 (&xsystem): Use WIFEXITED and WEXITSTATUS instead of decoding $? by
11192 hand, which is not portable.
11194 * bin/autom4te.in: Use them.
11195 Use &error instead of die.
11196 * tests/m4sugar.at (m4_warn, m4_require: circular dependencies):
11199 2002-08-17 Paul Eggert <eggert@twinsun.com>
11201 * lib/autoconf/fortran.m4 (AC_PROG_F77): Remove fc from the
11202 default list of compilers to try, since it was long ago superseded
11203 by the ksh fc builtin. Suggested by Steven G. Johnson.
11205 2002-07-31 Alexandre Duret-Lutz <duret_g@epita.fr>
11207 * doc/autoconf.texi (Invoking autom4te): End the option table,
11208 fixing a bug introduced by the previous patch.
11209 (Limitations of Make): Add a 'target lookup' subentry in the
11210 'VPATH' entry. Rewrite all `make' occurences as `@command{make}'.
11212 2002-07-29 Mark D. Roth <roth@feep.net>
11214 * bin/autom4te.in: Remove --include-envvar and --site-macro-subdir
11215 options and use $AUTOM4TE_PATH.
11216 * doc/autoconf.texi: Remove documentation of autom4te
11217 --include-envvar and --site-macro-subdir options and document
11218 use of $AUTOM4TE_PATH.
11219 * lib/autom4te.in: Remove --include-envvar and --site-macro-subdir
11220 arguments from each language section.
11222 2002-07-29 Paul Eggert <eggert@twinsun.com>
11224 * doc/install.texi: Include copyright symbol in copyright notice.
11226 * Makefile.am (MAKEINFO): Remove; it's a user-specified macro.
11228 (AM_MAKEINFOFLAGS): New macro.
11229 * doc/Makefile.am (MAKEINFO, AM_MAKEINFOFLAGS): Likewise.
11230 * Makefile.am (INSTALL): Use the new macros.
11231 Use -o rather than --output, since "missing" does not grok --output.
11233 2002-07-25 Alexandre Duret-Lutz <duret_g@epita.fr>
11235 * doc/autoconf.texi (Limitations of Make): Escaped newlines in
11236 comments do not always work. Never trust the exit status of
11239 2002-07-24 Kevin Ryde <user42@zip.com.au>
11241 * doc/autoconf.texi (Limitations of Make, Making testsuite Scripts):
11242 Untabify, since tabs are not enjoyed by texi2dvi and makeinfo.
11244 2002-07-23 Paul Eggert <eggert@twinsun.com>
11246 * lib/m4sugar/m4sh.m4 (_AS_PATH_SEPARATOR_PREPARE):
11247 Use PATH="/nonexistent;.", not PATH=".;.", as FreeBSD ksh2002
11248 apparently treats PATH="nonexistent" as if it contained ".".
11249 Bug reported by Stefan `Sec' Zehl.
11251 2002-07-22 Alexandre Duret-Lutz <duret_g@epita.fr>

11477 * bin/autom4te.in ($m4): Do not assume that egrep and fgrep exist.
11478 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Likewise.
11479 * lib/autoconf/general.m4 (_AC_RUN_LOG_STDERR, AC_EGREP_CPP):
11481 * lib/autoconf/Makefile.am (check-local): Likewise.
11482 * lib/autoconf/status.m4 (AC_CONFIG_HEADER): Likewise.
11483 * lib/autoconf/types.m4 (commentary only): Likewise.
11484 * lib/autotest/general.m4 (AT_INIT, AT_CHECK): Likewise.
11485 * lib/autotest/Makefile.am (check-local): Likewise.
11486 * lib/m4sugar/Makefile.am (check-local): Likewise.
11487 * tests/atspecific.m4 (AT_CONFIGURE_AC, AT_CHECK_DEFINES): Likewise.
11488 * tests/mktests.sh (egrep): New var; use it instead of plain egrep.
11490 * lib/autoconf/programs.m4 (AC_PROG_EGREP, AC_PROG_FGREP): New macros.
11491 * doc/autoconf.texi (Particular Programs): Document them.
11492 (Limitations of Usual Tools): Warn that egrep and fgrep may not exist.
11495 2002-05-27 Paul Eggert <eggert@twinsun.com>
11497 * lib/autoconf/types.m4 (AC_TYPE_MBSTATE_T): New macro.
11498 * NEWS, doc/autoconf.texi (Particular Types): Document it.
11499 * lib/autoconf/functions.m4 (_AC_FUNC_FNMATCH): Require it
11500 instead of AC_MBSTATE_T, which never existed.
11502 2002-05-23 Akim Demaille <akim@epita.fr>
11504 * doc/autoconf.texi (Hosts and Cross-Compilation): Specify the
11505 version of Autoconf that is discussed.
11507 2002-05-22 Paul Eggert <eggert@twinsun.com>
11509 * lib/autoconf/fortran.m4 (AC_PROG_F77): Remove cf77 and cft77
11510 from the default list of compilers to try. Suggested by
11512 * NEWS: Document the above.
11513 * doc/autoconf.texi (Fortran 77 Compiler): Don't suggest cf77.
11515 2002-05-17 Paul Eggert <eggert@twinsun.com>
11517 * lib/autoconf/types.m4 (AC_CHECK_MEMBER): Work correctly even if
11518 the member is itself an aggregate. Bug reported by Sergey Poznyakoff.
11519 This improves on an earlier suggestion by H. Peter Anvin.
11521 2002-05-16 Paul Eggert <eggert@twinsun.com>
11523 AC_FUNC_FNMATCH now tests only for POSIX compatibility.
11524 AC_FUNC_FNMATCH_GNU also tests for GNU extensions.
11525 Both macros now accept an optional source-dir arg.
11526 New macro AC_GNU_SOURCE to define _GNU_SOURCE.
11528 * NEWS: Document this.
11529 * doc/autoconf.texi (Particular Functions, UNIX Variants): Likewise.
11531 * lib/autoconf/functions.m4 (_AC_FUNC_FNMATCH): New macro.
11532 (AC_FUNC_FNMATCH): Use it. Test only for POSIX conformance,
11533 not for GNU extensions; this undoes part of the 2000-11-03 change,
11534 reverting to 2.13-compatible behavior.
11535 Add new optional argument DIR.
11536 (AC_FUNC_FNMATCH_GNU): New macro.
11538 * lib/autoconf/specific.m4 (AC_GNU_SOURCE): New macro.
11540 2002-05-08 Paul Eggert <eggert@twinsun.com>
11542 * lib/autoconf/headers.m4 (AC_HEADER_TIOCGWINSZ):
11543 Don't require AC_SYS_POSIX_TERMIOS. The test is unnecessary,
11544 and it causes a 'test' syntax error if it fails.
11545 Bug reported by Stephen Gildea.
11547 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
11548 If prototypes are supported, use them to check this at compile-time,
11549 instead of trying to check it at run-time. If we must do a run-time
11550 check, assume that setvbuf is standard when cross-compiling, as
11551 nonstandard setvbuf occurs only on ancient and unlikely hosts.
11552 Bug reported by Paul D. Smith.
11554 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Add optional
11555 argument specifying location of getloadavg.c. This removes a
11556 FIXME. This idea was taken from Jim Meyering's implementation in
11558 * doc/autoconf.texi (Particular Functions): Document this.
11559 Also, mention HAVE_NLIST_H rather than NLIST_STRUCT, since
11560 that's what the code does; this fixes a bug reported by
11563 2002-05-03 Akim Demaille <akim@epita.fr>
11565 * bin/autoreconf.in (autoreconf): Rewrite to use Gettext's
11566 autopoint instead of gettextize.
11567 ($uses_alocal): Rename as...
11568 ($uses_aclocal): this.
11569 * doc/autoconf.texi (autoreconf Invocation): Adjust.
11570 Suggested by Bruno Haible.
11572 2002-05-03 Akim Demaille <akim@epita.fr>
11574 * lib/m4sugar/m4sugar.m4 (m4_map_sep): New.
11576 2002-04-29 Paul Eggert <eggert@twinsun.com>
11578 * bin/autoreconf.in (autoreconf): Don't age aclocal.m4's input
11579 files to be 1 second older; just set them to be the same time.
11580 Also, sleep 1 second after the first aclocal, to work around
11581 problems with sub-second time stamps on the input files.
11583 2002-04-29 Thien-Thi Nguyen <ttn@gnu.org>
11585 * doc/autoconf.texi: Mention "set -e -x" lossage
11586 under node "Limitations of Builtins".
11588 2002-04-29 Akim Demaille <akim@epita.fr>
11590 * doc/install.texi: Better wording for setting variables when
11592 From Christian Cornelssen.
11594 2002-04-29 Akim Demaille <akim@epita.fr>
11596 * tests/m4sh.at (LINENO): If testsuite itself is rewritten because
11597 of lack of $LINENO support, then the test will compare the $LINENO
11598 in testsuite vs. the lineno in the test file. This is wrong, of
11600 Be sure to protect it.
11601 Reported by Patrick Welche.
11603 2002-04-25 Akim Demaille <akim@epita.fr>
11605 * doc/autoconf.texi (Obsolete Macros): Typo.
11606 Reported by Vladimir Volovich.
11608 2002-04-25 Akim Demaille <akim@epita.fr>
11610 * bin/autoreconf.in (autoreconf): Don't let aclocal.m4 be older
11611 than some of the input files, hence, on the second run of aclocal,
11612 if some of its input are younger, make them older.
11613 Suggested by Paul Eggert.
11615 2002-04-25 Akim Demaille <akim@epita.fr>
11617 * doc/autoconf.texi (Limitations of Usual Tools): sed and `!'.
11618 Thanks to Paul Eggert.
11620 2002-04-25 Akim Demaille <akim@epita.fr>
11622 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Let ac_subst_files
11623 and ac_subst_vars be sh variables containing the list of
11624 AC_SUBST_FILES'ed and AC_SUBST'ed identifiers. Output them in the
11626 (_AC_INIT_PREPARE): Use them to log them.
11627 (_AC_SUBST, _AC_SUBST_SED_PROGRAM): Remove.
11628 (AC_SUBST, AC_SUBST_FILE): Instead of buliding the
11629 _AC_SUBST_SED_PROGRAM, store the list of output files/variables in
11630 _AC_SUBST_FILES and _AC_SUBST_VARS.
11631 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Adjust.
11633 2002-04-24 Akim Demaille <akim@epita.fr>
11635 * bin/autoreconf.in (autoreconf): Run automake after autoconf and
11636 autoheader, so that automake does not complain about a missing
11637 config.h.in that was to be created.
11639 2002-04-23 Akim Demaille <akim@epita.fr>
11641 * bin/autoheader.in (parse_args): --warning takes an argument.
11644 2002-04-22 Peter Eisentraut <peter_e@gmx.net>
11646 * lib/autoconf/general.m4 (_AC_RUN_IFELSE): Remove gmon.out

11661 Reported by Gregory Giannoni.
11663 2002-04-22 Akim Demaille <akim@epita.fr>
11665 * tests/m4sh.at (LINENO): Skip the test if LINENO cannot be unset.
11666 Fixes false failures on Darwin.
11668 2002-04-21 Paul Eggert <eggert@twinsun.com>
11670 * TODO, bin/autoupdate.in, doc/autoconf.texi,

11672 lib/autoconf/status.m4, lib/m4sugar/m4sugar.m4, tests/m4sh.at,
11673 tests/tools.at: Minor spelling and grammar fixes.
11675 2002-04-20 Paul Eggert <eggert@twinsun.com>
11677 * doc/autoconf.texi (Shell Substitutions): Fix typos in yesterday's
11678 ZSH_VERSION fixes. Bug reported by Raja R Harinath.

11690 tests/atspecific.m4, tests/semantics.at, tests/torture.at:
11691 Minor spelling and grammar fixes.
11693 * doc/autoconf.texi: Follow the outline suggested in the GNU
11694 Sample Texts sections of the Texinfo 4.2 manual. Most
11695 importantly, this makes sure that the copyright notices appear in
11696 all output formats. You probably need Texinfo 4.2 to generate
11699 Fix some bugs when using "$@" when there might be zero positional
11700 arguments in cases where this matters.
11702 * bin/autoconf.as: Rewrite so that the problem does not come up.

11717 Use Zsh alias to work around problem.
11718 * tests/atgeneral.m4 (AT_INIT): Likewise.
11720 * tests/c.at: We can't have zero arguments, so remove workaround
11721 that is not portable to Zsh.
11723 2002-04-19 Alexandre Duret-Lutz <duret_g@epita.fr>
11725 * bin/autoupdate.in (handle_autoconf_macros): Honor AU_DEFUNs
11726 from aclocal.m4 too.
11728 2002-04-12 Akim Demaille <akim@epita.fr>
11730 * tests/wrappl.as: New, M4sh precursor of wrappl.in.
11732 2002-04-10 Akim Demaille <akim@epita.fr>
11734 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Install the Zsh
11735 workaround for ${1+"$@"}.
11736 * doc/autoconf.texi (Shell Substitutions): Explain it.
11737 From Oliver Kiddle and Peter Stephenson.
11739 Have M4sh perform minimal shell sanitizing.
11741 * lib/m4sugar/m4sh.at (AS_SHELL_SANITIZE): Split the `_AS_PREPARE_*'
11743 (_AS_PREPARE): this new macro.
11745 (AS_INIT): Invoke AS_SHELL_SANITIZE.
11746 * tests/m4sh.at (AT_DATA_LINENO): Use _AS_PREPARE.
11748 Adjust Autoconf and Autotest.
11750 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Don't invoke
11751 AS_SHELL_SANITIZE, AS_INIT did it, but invoke AS_PREPARE.
11752 * lib/autotest/general.m4 (AT_INIT): Likewise.
11753 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
11754 Invoke _AS_PREPARE (not AS_PREPARE) in addition to
11757 Use this M4sh to generate Autoconf's shell scripts.
11759 * tests/wrapsh.as: New, precursor of wrapsh.in.
11760 * tests/Makefile.am: Include lib/freeze.mk to get the dependencies
11761 on Autotest and M4sh.
11762 ($(TESTSUITE)): Use $(autotest_m4f_dependencies).
11763 (wrapsh.in): New target.
11764 * bin/autoconf.as: New, precursor of autoconf.in.
11765 (autoconf.in): New target.
11767 2002-04-09 Alexandre Duret-Lutz <duret_g@epita.fr>

11770 with indented comments in rules.
11772 2002-04-09 Andreas Schwab <schwab@suse.de>
11774 * lib/autoconf/status.m4 (_AC_SRCPATHS): Handle empty
11775 ac_top_builddir when setting ac_abs_top_builddir.
11777 2002-04-06 Kevin Ryde <user42@zip.com.au>
11779 * doc/autoconf.texi (Systemology): Add link to Unix V7 online docs.
11780 (Portable Shell): Cross reference to Systemology.
11782 2002-04-05 Akim Demaille <akim@epita.fr>
11784 * bin/autoreconf.in (autoreconf): Be sure to accumulate the
11785 directories when descending in a SUBDIRS.
11786 Reported by Ezra Peisach.
11788 2002-04-04 Andreas Schwab <schwab@suse.de>
11790 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Only simplify if path
11791 contains no literal separators.
11793 2002-04-03 Akim Demaille <akim@epita.fr>
11795 * lib/autoconf/status.m4 (_AC_CONFIG_FILE, _AC_CONFIG_HEADER)
11796 (_AC_CONFIG_COMMAND, _AC_CONFIG_LINK): New.
11797 Use dnl, not the KILL diversion.
11799 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_COMMANDS)
11800 (AC_CONFIG_LINKS): here.
11802 Don't use the KILL diversion, as it kills spurious output, which
11803 results in failures being hidden.
11804 Use m4_defn where appropriate.
11805 (AC_CONFIG_IF_MEMBER): Kill the real bug: a spurious parenthesis
11806 after the second argument.
11808 * lib/autom4te.in (Autoconf, Autotest, M4sh): Don't pass --warning
11809 syntax, as it is provided by M4sugar.
11810 * tests/torture.at (Multiple AC_CONFIG_FILES): New.
11812 2002-04-03 Andreas Schwab <schwab@suse.de>
11814 * lib/m4sugar/m4sugar.m4 (m4_bmatch): Make sure m4_bregexp is not
11815 expanded if $# <= 2.
11817 * bin/autoreconf.in (autoreconf): Run automake after rerunning
11820 2002-04-03 Akim Demaille <akim@epita.fr>

11826 (_AC_COMPILER_OBJEXT): Use them.
11827 Fixes Debian #138666.

11831 Integrate AC_PROG_CC_STDC into AC_PROG_CC.
11833 * lib/autoconf/c.m4 (AC_PROG_CC_STDC): Rename to _AC_PROG_CC_STDC.
11834 AU_DEFUN old name. Use _AC_COMPILE_IFELSE.
11835 (AC_PROG_CC): Call _AC_PROG_CC_STDC.

11837 (AC_C_CONST): Same.

11847 _AS_MKDIR_P_PREPARE.
11849 2002-03-28 Kevin Ryde <user42@zip.com.au>
11851 * lib/autoconf/c.m4 (AC_C_INLINE): Test with a typedef return value,
11852 to avoid versions of HP C which don't allow that.
11854 2002-03-27 Paul Eggert <eggert@twinsun.com>
11856 * lib/m4sugar/m4sh.m4 (_AS_BASENAME_PREPARE): New macro.
11857 (AS_SHELL_SANITIZE): Invoke it.
11858 (AS_BASENAME): AS_REQUIRE it, and use $as_basename.

11868 2002-03-25 Paul Eggert <eggert@twinsun.com>
11870 * tests/m4sh.at: Don't rely on "PATH=test:$PATH test-1" working
11871 as POSIX requires, as it doesn't work with Zsh.
11872 * doc/autoconf.texi (Assignments): Document the problem.
11874 2002-03-25 Alexandre Duret-Lutz <duret_g@epita.fr>
11876 * doc/autoconf.texi (Limitations of Make): Mention more issue
11877 about VPATH, overriding of macros in sub-makes, and handling of
11880 2002-03-21 Paul Eggert <eggert@twinsun.com>
11882 * doc/autoconf.texi (Here-Documents): Mention Solaris 8 dtksh
11883 problem with here-document buffer boundaries.
11885 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Unset ENV and BASH_ENV
11886 when reinvoking the shell, to work around problems with installers
11887 who put strange things like "cd" commands in their environments.
11889 2002-03-19 Akim Demaille <akim@epita.fr>

11903 From Nishio Futoshi.
11905 2002-03-19 Akim Demaille <akim@epita.fr>
11907 * lib/m4sugar/m4sugar.m4 (m4_define_default, m4_fst, m4_map): New.
11909 2002-03-18 Paul Eggert <eggert@twinsun.com>
11911 * doc/autoconf.texi (Programming in M4sh): Add AS_MKDIR_P.
11912 (Limitations of Usual Tools): Add mkdir section.
11914 * lib/m4sugar/m4sh.m4 (_AS_MKDIR_P_PREPARE): New macro.
11915 (AS_MKDIR_P): Require it. Use mkdir -p if available, falling
11916 back on AS_DIRNAME to compute prefixes otherwise; this is
11917 roughly what mkinstalldirs does. That way, we need not have
11918 our own filename disassembler. The old disassembler did not
11919 work with Solaris 8 dtksh, which is ksh Version M-12/28/93d.
11921 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP):
11922 Create at_test_all by a series of assignments,
11923 not by a single assignment of a long string. The latter causes ksh
11924 version 11/16/88g to silently misbehave on OpenServer 5.0.6a,
11925 presumably because of a buffer overrun.
11927 2002-03-14 Paul Eggert <eggert@twinsun.com>
11929 * lib/autotest/general.m4 (at_times_skip):
11930 Renamed from at_times. Now a boolean.
11931 ksh93 Version M-12/28/93d doesn't like 'x=times; $x'; it
11932 says 'times: not found'.
11934 2002-03-14 Akim Demaille <akim@epita.fr>
11936 * bin/autoreconf.in (&study_gettextize): New.
11937 (&autoreconf): Handle newest gettextize.

11982 aliases the actual variables, and modifications of the former

11987 * bin/autom4te.in (&handle_m4): Protect us from corrupted file

12020 2002-03-04 Akim Demaille <akim@epita.fr>
12022 * doc/autoconf.texi (Transforming Names): Equality between target
12023 and host is irrelevant.
12024 (Specifying Names, Canonicalizing): Remove all references to the
12025 backward compatibility hooks. Rather, collect them all into...
12026 (Hosts and Cross-Compilation): this new section.
12027 * doc/install.texi (System Type): Ditto.
12028 * lib/autoconf/general.m4 (AC_CANONICAL_HOST): Explicitly state
12029 that `--host' implies cross-compilation.

12033 * doc/autoconf.texi (Evaluation Macros): New.
12034 * lib/m4sugar/m4sugar.m4 (m4_lquote): Remove, it is totally

12041 2002-03-04 Akim Demaille <akim@epita.fr>
12043 Instead of having stacking `shift's evaluated at the end, let
12044 `foreach' loops immediately evaluate them.
12046 * lib/m4sugar/m4sugar.m4 (m4_quote, m4_dquote): Use $@ rather than
12047 $*. This is the n-th time I change my mind, but hopefully this is
12050 (m4_text_wrap): Use m4_foreach, which is finally correct _and_
12052 (m4_foreach_quoted, m4_car_quoted, _m4_foreach_quoted): Remove, as
12053 it was only a hack for m4_text_wrap.
12054 (m4_car2): Remove, replaced by...
12056 (_m4_foreach): Adjust.
12057 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Adjust, and use
12058 m4_bpatsubst for clarification.

12149 2002-02-05 Akim Demaille <akim@epita.fr>
12151 * tests/Makefile.am (check_SCRIPTS): Use it, instead of WRAPPERS,

12174 optional are the sum of the previous files on the command line'.
12175 Also, pass `--reload-state=' on them, so...
12176 (handle_m4): don't.

12216 2002-01-28 Akim Demaille <akim@epita.fr>
12218 * lib/autotest/general.m4 (AT_INIT): Don't be ridiculous: adjust
12219 AUTOTEST_PATH *after* it was set.
12220 Don't put `.' in the PATH: the user should be precise and `./' if
12221 needed. In addition, given that the test suite does some `cd', if
12222 `.' is in the path, the `tested programs' sections will report
12223 programs found in the test suite's directory, while during the
12224 tests (performed in their own directory), these programs are no
12225 longer visible. In other words, the results is confusing and
12227 * tests/m4sh.at: Adjust: don't rely on `.' being in the PATH.

12297 EXTRA_DIST it since its a source.

12302 of PACKAGE_NAME, PACKAGE_TARNAME, PACKAGE_VERSION, PACKAGE_STRING,
12303 and PACKAGE_BUGREPORT from here...
12304 (_AC_INIT_DEFAULTS): to here, since it is unrelated to the
12306 (_AC_INIT_PREPARE): AC_DEFINE these symbols.
12307 * lib/autotest/general.m4: Use AT_PACKAGE_*, not PACKAGE_*.
12308 (AT_INIT): No longer catch `^PACKAGE_(BUGREPORT|STRING)$'.

12334 trailing files, don't apply `-rf' to files which might not be

12336 Suggested by Jonathan Kamens.
12338 2001-12-14 Aaron M. Ucko <amu@alum.mit.edu>

12451 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C)): Make the array
12452 static, to catch errors if the value isn't known at compile-time
12453 and the compiler supports dynamic arrays. Change its name from
12454 `_array_' to `test_array' to avoid potential name clashes.
12455 (AC_C_LONG_DOUBLE): Make it a compile-time test, not a run-time
12456 test. Do not define HAVE_LONG_DOUBLE if `long double' is no
12457 better than double. Catch a bug in GCC 2.95.2 x86.

12474 * tests/atspecific.m4 (AT_DATA_M4SUGAR, AT_DATA_M4SH)
12475 (AT_DATA_AUTOCONF): Also protect @&t@ from autom4te.
12476 (AT_CHECK_AUTOCONF, AT_CHECK_AUTOHEADER): Pass no --include
12478 (AT_CHECK_CONFIGURE): Use absolute paths.
12479 (_AT_CHECK_AC_MACRO): Create aclocal.m4 with AC_STATE_SAVE in it.
12480 The problem is still the old one: there is no means in M4 (that I
12481 know about) to create a defining macro, because there is no means
12482 to create `$1' etc., therefore, the defining macro ``swallows''
12483 all the arguments meant to the defined macro.
12485 2001-11-13 Akim Demaille <akim@epita.fr>
12487 * tests/atspecific.m4 (AT_DATA_AUTOCONF): New.
12488 (AT_CONFIGURE_AC): Output the definition of AC_STATE_SAVE in
12490 * tests/aclocal.m4: Remove, as it is no longer used.
12492 2001-11-13 Akim Demaille <akim@epita.fr>
12494 * lib/autotest/general.m4: Change `tests?' into `groups?' in
12495 variable names when referring to a single test group, or to
12496 `suite' when referring to the whole test suite.
12497 `at_last_test' is removed: m4 compute at_format itself.
12498 (at_stdout, at_stder1, at_stderr): New variables.
12499 (AT_CHECK): Use them.
12501 2001-11-13 Akim Demaille <akim@epita.fr>
12503 * lib/autotest/general.m4 (AT_INIT): Be sure to put `.', relative,
12505 Create `testsuite.dir/003/run' instead of `testsuite.003'.
12506 Do it as soon as a test fails, don't wait till the end of the test
12508 Don't remove $as_me.[0-9]*, since these files no longer exist.
12510 2001-11-13 Akim Demaille <akim@epita.fr>
12512 * tests/tools.at: Use absolute paths, since we are no longer run
12515 2001-11-13 Akim Demaille <akim@epita.fr>
12517 Now that tests are running in their own private dir, there is no
12518 need to list the files to remove at the end of tests groups.
12520 * lib/autotest/general.m4 (_AT_CLEANUP_FILE, AT_CLEANUP_FILES):
12521 (AT_data_files, at_data_files): Remove.
12522 (AT_CLEANUP, AT_DATA): Simplify.
12524 Remove the group dir if !debug && !failed.
12525 * tests/atspecific.m4: Adjust.
12527 2001-11-13 Akim Demaille <akim@epita.fr>
12529 Start a new layout for Autotest: `testsuite' creates
12530 `testsuite.dir' in which the at-check-line etc. files are to be
12531 found, and `testsuite.dir/003' where the test group 3 is run.
12533 * lib/autotest/general.m4 (AT_INIT): at_tests_dir,
12534 at_check_line_file, at_format, at_test_normalized, at_group_dir
12536 Create the directories.
12537 Use absolute paths for at- files.
12538 (AT_CHECK): Adjust.
12540 2001-11-11 Michael Matz <matz@kde.org>
12542 * m4sugar.m4 (_m4_foreach): Make it linear instead quadratic.
12544 (m4_car): Properly quote arguments.
12546 2001-11-13 Akim Demaille <akim@epita.fr>
12548 * tests/aclocal.m4 (AC_STATE_SAVE): s/LIBOBJS/LIB@&t@OBJS/ to cope
12549 with stricter rules on LIBOBJS.
12551 2001-11-12 Paul Eggert <eggert@twinsun.com>
12553 * lib/autoconf/c.m4 (AC_C_PROTOTYPES): Define __PROTOTYPES too.
12554 * doc/autoconf.texi (C Compiler): AC_C_PROTOTYPES now defines
12557 2001-11-12 Akim Demaille <akim@epita.fr>
12559 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT): Use AC_CHECK_FUNCS.
12561 2001-11-12 Akim Demaille <akim@epita.fr>
12563 * lib/autoconf/c.m4, lib/autoconf/fortran.m4,
12564 * lib/autoconf/functions.m4, lib/autoconf/general.m4,
12565 * lib/autoconf/headers.m4, lib/autoconf/libs.m4,
12566 * lib/autoconf/programs.m4, lib/autoconf/specific.m4,
12567 * lib/autoconf/types.m4: When invoking AC_DEFINE and friends,
12568 specify to what the macro should be defined (typically to 1).
12570 2001-11-12 Akim Demaille <akim@epita.fr>
12572 * lib/autoconf/functions.m4 (AC_FUNC_STRTOD): AC_SUBST POW_LIB.
12575 2001-11-12 Akim Demaille <akim@epita.fr>
12577 * lib/autoconf/programs.m4 (_AC_PROG_LEX_YYTEXT_DECL): Use
12578 AC_TRY_EVAL to run $LEX, not AC_TRY_COMMAND. This validates the
12579 definition used by Automake where LEX is +/- "${missing} lex" and
12580 `missing' itself contains variables.
12582 2001-11-12 Akim Demaille <akim@epita.fr>
12584 * lib/autotest/general.m4 (AT_INIT): Push KILL at the end.
12585 Now that M4sh pushes BODY, the comments were output at the end of
12588 2001-11-08 Akim Demaille <akim@epita.fr>
12590 * bin/autoreconf.in (&autoreconf): Run aclocal before tracing, so
12591 that we can trace macros from aclocal.m4.
12592 Trace AC_PROG_LIBTOOL, not AM_PROG_LIBTOOL, since the latter is
12593 obsoleted, and redirect to the former anyway.
12594 Reported by Ralf Corsepius.
12596 2001-11-08 Akim Demaille <akim@epita.fr>
12598 * bin/autoreconf.in (&autoreconf): AC_CONFIG_SUBIDRS are to be
12599 processed only if present.
12600 * tests/torture.at (Configuring subdirectories): Use autoreconf
12601 instead of successive calls to autoconf.
12602 Add a nonexistent subdirectory to exercise the patch above.
12603 Reported by Ralf Corsepius.
12605 2001-11-08 Kevin Ryde <user42@zip.com.au>
12607 * doc/autoconf.texi (Limitations of Usual Tools): Note HP-UX cc
12608 doesn't accept .S files.
12610 2001-11-07 Akim Demaille <akim@epita.fr>
12612 * lib/m4sugar/m4sugar.m4 (m4_pattern_forbid): Accepts $2.
12613 * lib/autoconf/general.m4 (AC_INTI): Forbid LIBOBJS.
12614 (_AC_LIBOBJ): s/LIBOBJS/LIB@&t@OBJS/.
12615 * bin/autom4te.in (warn_forbidden): New.
12616 (handle_output): Use it.
12617 Read m4_pattern_forbid with messages.
12619 2001-11-05 Akim Demaille <akim@epita.fr>
12621 * bin/autom4te.in (--normalize): Remove.
12622 * lib/autom4te.in: Adjust.
12624 2001-11-05 Akim Demaille <akim@epita.fr>
12626 * tests/Makefile.am (testsuite): Rename this target as...
12627 ($(TESTSUITE)): this.
12630 2001-11-05 Alexandre Duret-Lutz <duret_g@epita.fr>
12632 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): When removing
12633 the --prefix option, also remove it's argument.
12635 2001-11-05 Akim Demaille <akim@epita.fr>
12637 * doc/autoconf.texi (testsuite Invocation): Update.
12638 (Writing testsuite.at): Update.
12640 2001-11-03 Akim Demaille <akim@epita.fr>
12642 * doc/autoconf.texi: s/@code/@command/ where appropriate.
12644 2001-11-03 Akim Demaille <akim@epita.fr>
12646 * lib/Autom4te/General.pm: (&catfile, &canonfile)
12647 (&file_name_is_absolute): New, wrappers around routines from
12649 Use and export them.
12650 (&find_configure_ac): Optionally take a directory where to look at.
12651 * bin/autoreconf.in (&parse_args): Trim the configure.ac part of
12653 Default @ARGV to `.', not find_configure_ac.
12654 (&autoreconf): Argument is a directory.
12655 Trace AC_CONFIG_SUBDIRS and schedule the subdirs for autoreconf'ing.
12656 * doc/autoconf.texi (autoreconf Invocation): Update.
12658 2001-11-03 Akim Demaille <akim@epita.fr>
12660 * lib/Autom4te/General.pm (@export_vars, @export_subs)
12661 (@export_forward_subs): New.
12662 Add basename, dirname, and fileparse.
12664 * bin/autoreconf.in (&autoreconf): Fix call to fileparse.
12665 Don't look for aclocal flags if we already know aclocal is not
12667 Move aclocal.m4t only if it exists.
12668 Reported by Ezra Peisach.
12670 2001-11-03 Akim Demaille <akim@epita.fr>
12672 * bin/autoreconf.in (&parse_args): Work only on the configure.ac
12673 passed on command line, defaulting to ./configure.ac if present.
12674 (&maybe_autoreconf, File::Find): Remove, unused.
12675 (&autoreconf): If autoconf is not used, don't try to trace.
12677 2001-11-02 Akim Demaille <akim@epita.fr>
12679 * configure.ac: Bump to 2.52g.
12681 2001-11-02 Akim Demaille <akim@epita.fr>
12685 2001-11-02 Akim Demaille <akim@epita.fr>
12687 * config/config.guess, config/config.sub, doc/standards.texi:
12688 * config/lispdir.m4: Update from masters.
12689 * configure.ac: Bump to 2.52f.
12691 2001-11-02 Akim Demaille <akim@epita.fr>
12693 * bin/autoreconf.in (&autoreconf): Set `$aclocal_flags' to ''.
12694 Don't run aclocal when aclocal.m4 is not from aclocal.
12696 Don't run libtoolize and gettextize if --install is not given.
12698 2001-11-01 Paul Eggert <eggert@twinsun.com>
12700 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): _AS_CR_PREPARE needs to
12701 be invoked before _AS_LINENO_PREPARE.
12702 (_AS_LINENO_PREPARE): Use as_cr_digits and as_cr_alnum rather
12703 than character ranges.
12705 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Fix NLS before
12706 invoking AS_BASENAME. Set the locale variables to 'C' if
12707 possible, as POSIX requires this to get the traditional
12709 * doc/autoconf.texi (Special Shell Variables): Describe the above.
12711 2001-10-31 Paul Eggert <eggert@twinsun.com>
12713 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): Do not surround body
12714 with {}, as that triggers a bug in Bash 2.05.
12716 (_AS_LINENO_PREPARE): Use Sed rather than
12717 Awk. Fix the sed prepass to work even if there are multiple
12718 instances of $LINENO on the same line. Do not substitute for
12719 other variables like $LINENOT. Do not check file dates; such a
12720 check is unreliable on sufficiently fast machines, and removing
12721 the check makes the code simpler and more reliable. Check for
12722 output and chmod failures.
12724 * doc/autoconf.texi (Special Shell Variables): Document
12727 2001-10-31 Akim Demaille <akim@epita.fr>
12729 * tests/Makefile.am (atconfig): Remove this target, Automake
12732 2001-10-31 Akim Demaille <akim@epita.fr>
12734 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Do not
12735 AC_CONFIG_FILES(atlocal) as it means a file atlocal.in *must* be
12736 provided, while it is optional.
12737 * configure.ac: Adjust.
12739 2001-10-26 Paul Eggert <eggert@twinsun.com>
12741 * NEWS, README, configure.ac, lib/Autom4te/General.pm,
12742 lib/Autom4te/Struct.pm:
12743 Require Perl 5.005_03 instead of just 5.005, as some tests fail
12746 * doc/autoconf.texi (Special Shell Variables): Document some
12747 more LINENO gotchas, particularly with respect to the Awk+Sed hack.
12749 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): New macro.
12750 (_AS_LINENO_PREPARE): Use it instead of shell eval, since
12751 eval $LINENO is not portable in practice.
12753 2001-10-24 Akim Demaille <akim@epita.fr>
12755 * lib/Autom4te/General.pm (backname): New.
12757 2001-10-24 Akim Demaille <akim@epita.fr>
12759 * m4/: Remove, merged into...
12762 2001-10-23 Tim Van Holder <tim.van.holder@pandora.be>
12764 * doc/autoconf.texi (Shellology): Mention the problems with bash
12765 2.05's use of ANSI quoting in its `set' builtin.
12767 2001-10-22 Paul Eggert <eggert@twinsun.com>
12769 * lib/autoconf/functions.m4 (AC_FUNC_STRERROR_R):
12770 Rename ac_cv_func_strerror_r_works to ac_cv_func_strerror_r_char_p,
12771 and rename HAVE_WORKING_STRERROR_R to STRERROR_R_CHAR_P, since
12772 POSIX decided to standardize on the int flavor of strerror_r.
12773 Always do char* test, as there's no reason not to.
12774 Assign to a char* var, to catch strerror_r that returns int*.
12776 * doc/autoconf.texi (Particular Functions):
12777 Document the above changes. Also, document the fact that
12778 AC_FUNC_STRERROR_R defines HAVE_DECL_STRERROR_R.
12780 * NEWS: Mention HAVE_WORKING_STRERROR_R -> STRERROR_R_CHAR_P.
12782 2001-10-20 Akim Demaille <akim@epita.fr>
12784 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): The name of
12785 the executable was missing from the log.
12787 2001-10-20 Akim Demaille <akim@epita.fr>
12789 * lib/Autom4te/General.pm (&update_file): If destination is
12790 unchanged, remove the source.
12791 (&up_to_date_p): Don't be verbose, be debug.
12792 * bin/autoreconf.in: No longer support --m4dir.
12793 (&autoreconf): Display the full path of the configure.ac we are
12795 Trace it only once.
12796 Be sure to honor --force with gettextize.
12797 Always run aclocal.
12798 * doc/autoconf.texi: Adjust.
12800 2001-10-20 Akim Demaille <akim@epita.fr>
12802 * bin/autoheader.in ($localdir, $m4, $SIMPLE_BACKUP_SUFFIX):
12804 * bin/autoreconf.in (&autoreconf): Do not run gettextize when
12805 `intl' is already present, as it refuses unless --force.
12806 (&parse_args): Use -I, --include instead of the old Autoconf
12808 ($localdir, $autoconf_dir): Remove.
12810 (&maybe_autoreconf): New, to preserve $_ for File::Find.
12812 2001-10-19 Jens Petersen <petersen@redhat.com>
12814 * lib/autoconf/programs.m4 (AC_PROG_AWK): Prefer gawk to mawk.

12821 Don't mention `automatically' in addition to `generated'.
12822 * tests/torture.at (#define header templates): Adjust.
12824 2001-10-19 Akim Demaille <akim@epita.fr>
12826 * lib/emacs/autoconf-mode.el, lib/emacs/autotest-mode.el: In a
12827 comment, explain how to install automatic mode selection.
12830 2001-10-19 Ezra Peisach <epeisach@zif.mit.edu>
12832 * bin/autoreconf.in (autoreconf): Display the path to the
12833 configure.ac being studied.
12835 2001-10-18 Paul Eggert <eggert@twinsun.com>
12837 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Cast sizeof to unsigned
12838 long, to work around a bug in the HP C compiler version HP92453-01
12841 * lib/m4sugar/m4sh.m4 (AS_DIRNAME): Use 'dirname' if that works.
12842 (AS_BASENAME_EXPR): New macro.
12843 (AS_BASENAME_SED): Do not assume GNU sed semantics.
12844 (AS_BASENAME): Use 'basename' if that works; then try 'expr';
12845 and fall back on 'sed' only if the other two fail. This makes
12846 AS_BASENAME act more like AS_DIRNAME.
12847 (as_me): Shell-quote the argument of AS_BASENAME, in case $0
12848 contains white space.
12849 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR):
12850 Use AS_DIRNAME, since I think it's now DOS-friendly.
12851 * tests/m4sh.at (DIRNAME_TEST): New arg $3.
12852 Allow "dirname //FOO" to return either / or //, as POSIX allows
12855 2001-10-10 Akim Demaille <akim@epita.fr>
12857 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Recognize

12861 2001-10-10 Akim Demaille <akim@epita.fr>
12863 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N_PREPARE): m4_defun, not
12864 m4_define, since...
12865 (_AS_ECHO_N): AS_REQUIREs it.
12867 2001-10-10 Akim Demaille <akim@epita.fr>
12869 * lib/autoconf/general.m4 (_AC_INCLUDES_DEFAULT_REQUIREMENTS)

12956 M4sugar peer, i.e., drop the `AC_PROVIDE_$1' broken marker.
12958 2001-10-08 Akim Demaille <akim@epita.fr>
12960 Use `add-log-current-defun-function' for ChangeLog creation.
12961 Suggested by Tom Tromey.
12963 * lib/emacs/autotest-mode.el (autotest-mode-map): New.
12964 (autotest-mode): Adjust.
12965 * lib/emacs/autoconf-mode.el (autoconf-mode-map): Modernize, map

12977 (AT_INIT): Replace AC_PLAIN_SCRIPT with AS_INIT invocation,
12978 include handle the m4_pattern_*, no longer push the

12992 shell does not support LINENO, and if CONFIG_SHELL is unset or
12993 empty, and if we can find a shell that does support LINENO,
12994 then set CONFIG_SHELL to that shell and then re-execute
12995 ourselves with CONFIG_SHELL.
12997 2001-10-05 Paul Eggert <eggert@twinsun.com>
12999 * tests/Makefile.am (clean-local): Don't invoke $(TESTSUITE) if it
13000 doesn't exist. Remove *.tmp, as a .tmp file is created during the
13001 build of $(TESTSUITE).
13003 2001-10-05 Akim Demaille <akim@epita.fr>

13042 compatibility with POSIX shells.

13070 * lib/autoconf/status.m4 (AC_OUTPUT_MAKE_DEFS):
13071 Don't use nested parenthesization. This patch was originally
13072 suggested to bug-autoconf by Philippe De Muyter on 2000-05-28,
13073 but somehow it didn't get incorporated then.
13074 * doc/autoconf.texi (Limitations of Usual Tools):

13081 Check for `expr' arithmetic overflow, and for compilation failure,
13082 and invoke a new argument $4 if either is discovered.
13083 This makes _AC_COMPUTE_INT_COMPILE more like _AC_COMPUTE_INT_RUN.
13084 (_AC_COMPUTE_INT): Pass IF-FAILS arg to _AC_COMPUTE_INT_COMPILE.
13086 2001-09-28 Akim Demaille <akim@epita.fr>

13118 * tests/fortran.at (GNU Fortran 77): there.
13119 * doc/autoconf.texi (autoconf Invocation): Fix the example:
13120 AC_TRY_RUN is about compilation, not shell commands.

13150 * lib/autoconf/status.m4 (_AC_SRCPATHS): Compute and provide
13151 ac_buildpath, ac_top_buildpath, ac_srcpath, and ac_top_srcpath.

13162 * lib/autotest/general.m4: Do not reset AT_victims.
13163 Don't compute at_srcdir nor at_top_srcdir.
13165 * tests/tools.at: Hence use top_srcdir.
13167 * tests/Makefile.am, tests/autoconf, tests/autoheader,
13168 * tests/autom4te, tests/autoreconf, tests/autoupdate, tests/ifnames:

13224 * lib/autoconf/autotest.m4: Create `package.m4'.
13225 * tests/Makefile.am (package.m4): Remove.
13227 2001-09-22 Akim Demaille <akim@epita.fr>
13229 Rely on `$LINENO' when possible instead of `__oline__'.
13231 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Provide some form of
13232 `$LINENO' support replacement when not supported.
13233 (_AS_CR_PREPARE, _AS_TR_CPP_PREPARE, _AS_TR_SH_PREPARE): Invoke

13237 * lib/autoconf/programs.m4: Replace all the occurrences of
13238 `__oline__' with `$LINENO'.
13239 * doc/autoconf.texi (Special Shell Variables): Document LINENO.
13241 2001-09-21 Tim Van Holder <tim.van.holder@pandora.be>
13243 * lib/autoconf/functions.m4 (_AC_FUNC_FORK): Replaceded an 8-bit

13248 2001-09-21 Akim Demaille <akim@epita.fr>
13250 * Makefile.maint (AUTOM4TE): Neutralize autom4te.
13251 Suggested by Jim Meyering.
13253 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
13255 * lib/autoconf/programs.m4: Use extensions listed in
13256 $ac_executable_extensions when looking for programs.
13258 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
13260 * lib/autoconf/general.m4: Fix a small Englisho.

13269 (Special Shell Variables[PATH_SEPARATOR]): Ditto.
13270 (Special Shell Variables[CDPATH]): Mention that $PATH_SEPRATOR should
13271 be used instead of ':'.
13272 * lib/autotest/general.m4: Replace occurrences of ':' in
13273 AUTOTEST_PATH with $PATH_SEPARATOR at test suite startup.
13275 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
13277 * tests/atgeneral.m4: Add basic support for test ranges (e.g. 7-34) as
13278 arguments. Fixed a typo.
13280 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
13282 * man/Makefile.am (.x.1): Use @PATH_SEPARATOR@, not ':' to set up
13283 $PATH. Also set AUTOM4TE_CFG, so we can process autom4te properly.
13285 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
13287 * bin/autoscan.in: Add 'exec-perl-if-not-run-by-perl'.
13288 * bin/autoupdate.in: Ditto.
13289 * bin/autoheader.in: Reworded a few comments.

13294 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
13296 * lib/Autom4te/XFile.pm (open): Simplified the error message (we
13297 already have $file). Set output files to binary mode (helps avoid
13298 CR issues on DOSish systems).
13300 2001-09-19 Akim Demaille <akim@epita.fr>
13302 * lib/autotest/general.m4: Englishoes.
13303 From Tim Van Holder and Alexey Mahotkin.
13305 2001-09-18 Paul Eggert <eggert@twinsun.com>
13307 * doc/autoconf.texi (Common Shell Constructs): New node,
13308 documenting AS_DIRNAME.
13309 (Limitations of Usual Tools): Refer to it when discussing dirname.
13310 Also, update discussion of POSIX standard to reflect latest draft.
13312 * lib/autoconf/c.m4:
13313 (AC_LANG_INT_SAVE(C)): Also support negative values, down to LONG_MIN.
13315 * lib/autoconf/general.m4 (_AC_COMPUTE_INT_COMPILE):
13316 Do not pass a first argument with leading '-'
13317 to expr, by parenthesizing initial integers that might be negative.
13319 * doc/autoconf.texi (Particular Functions): AC_FUNC_GETPGRP
13320 now merely checks whether it is an error to pass an argument
13323 * lib/autoconf/functions.m4 (_AC_FUNC_GETPGRP_TEST): Remove.
13324 (AC_FUNC_GETPGRP): Don't bother with a runtime test. Just check
13325 whether it is a (compile-time) error to pass an argument to
13326 getpgrp. This simpler test supports the revised documentation,
13327 and is all that AC_FUNC_GETPGRP's users really need.
13329 2001-09-18 Akim Demaille <akim@epita.fr>
13331 * doc/autoconf.texi (Limitations of Make) <$<>: New.
13333 2001-09-18 Akim Demaille <akim@epita.fr>

13339 2001-09-18 Paul Wagland <paul@wagland.net>
13341 * tests/m4sh.at: Ensure that AS_DIRNAME handles '/', '//' and '///'
13343 Add test for AS_BASENAME.
13344 * lib/m4sugar/m4sh.m4: Fix AS_BASENAME so that it passes the previous
13345 added test. It now correctly handles /1/2/3/, returning '3' not ''.
13346 Added AS_BASENAME_SED to make the interface the same as AS_DIRNAME.
13347 * tests/base.at: Fixed the expected responses. The old ones were
13349 * lib/autoconf/general.m4: Fixed AC_PREFIX_PROGRAM, it now behaves as
13350 the documentation claims it should (and how it behaved in 2.13).
13352 2001-09-18 Akim Demaille <akim@epita.fr>
13354 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): No INIT-CMDS in
13355 the AC_CONFIG_COMMANDS invocation.
13356 This also solves the name clash problems.
13357 Don't set the package's ID.
13358 * lib/m4sugar/Makefile.am (version.m4): Revamp.
13359 No longer to be shipped.
13360 (version.in): Remove.
13361 * lib/m4sugar/m4sugar.m4, lib/autoconf/general.m4,
13362 * lib/autoconf/status.m4: Adjust.
13363 Use `m4_PACKAGE_STRING'.
13364 * lib/autotest/general.m4 (AT_INIT): N-th signature change: now
13365 the only optional argument is the name of the test suite.
13366 Expect `package.m4' to define the package signature.
13367 * lib/autom4te.in (Autotest): Add `package.m4?'.
13368 * tests/Makefile.am (package.m4): New.
13369 * tests/suite.at: ifnames is a victim.
13371 2001-09-18 Akim Demaille <akim@epita.fr>
13373 * lib/autom4te.in (Autoconf): Preselect AM_CONDITIONAL,
13374 AC_LIBSOURCE, AC_CONFIG_FILES.
13375 * lib/autotest/general.m4 (AT_INIT): Don't abort when a tested
13376 program version string doesn't match the package's.
13377 * lib/autoconf/general.m4 (AC_CACHE_VAL): Reestablish the space
13380 2001-09-17 Paul Eggert <eggert@twinsun.com>
13382 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):
13383 Allow expression to return any value that can fit into unsigned long
13384 (not int, as before). Check for output errors.
13386 2001-09-17 Bruno Haible <haible@ilog.fr>
13388 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):
13389 Always include <stdio.h> and <stdlib.h>. Evaluate
13390 the expression in an extra function before these includes. Call
13391 fprintf "%d" only after ensuring the argument is of type 'int'.
13392 Reported by Wayne Chapeskie <waynec@spinnaker.com>.
13394 2001-09-17 Paul Eggert <eggert@twinsun.com>
13396 Fix bug reported by Paul Townsend on AIX 4.3.3.0 with CFLAGS=-O4
13397 or CFLAGS=-O5. In that case, the linker has a relaxed view of
13398 fatal errors, and AC_CHECK_LIB causes it to include libraries even
13399 when they don't exist.
13401 * lib/autoconf/headers.m4 (AC_HEADER_DIRENT): Use AC_SEARCH_LIBS,
13402 not AC_CHECK_LIB, so that we don't use -ldir or -lx if we don't
13405 * lib/autoconf/specific.m4 (AC_ISC_POSIX): Replace the old, crufty
13406 version with the version used by fileutils 4.1, except use
13407 AC_SEARCH_LIBS, not AC_CHECK_LIB, so that we don't use -lcposix if
13410 * doc/autoconf.texi (AC_ISC_POSIX): Describe new behavior.
13412 2001-09-13 Akim Demaille <akim@epita.fr>
13414 * tests/base.at, tests/m4sh.at: Be sure to issue the bangshe line
13416 Reported by Gerrit P. Haase.

13643 * lib/Autom4te/General.pm (&find_file): Browse the includes in the

13750 find the executables for it.

13752 * tests/atlocal.in: Remove all the obscure envvar manipulations.
13754 * tests/atspecific.m4, tests/tools.at: Passing --localdir is
13755 indeed related to running the test suite, while passing

13779 2001-08-29 Akim Demaille <akim@epita.fr>

14345 current $prefix to the sub-configures.
14347 2001-08-09 Tim Van Holder <tim.van.holder@pandora.be>
14349 * lib/autoconf/lang.m4: Ignore *.xSYM when looking for an executable
14350 extension (needed on BeOS). Reported by Guido van Rossum.
14352 2001-08-09 Akim Demaille <akim@epita.fr>
14354 * bin/autom4te.in ($icache): Load it only if older than autom4te.
14356 2001-08-07 Akim Demaille <akim@epita.fr>
14358 * lib/autotest/general.m4 (AT_INIT): All the `at-*' are to be
14360 (at-setup-line): Huh? Be a variable `at_setup_line', not a file.
14361 No need to remove the files before and after the each test, before
14362 each test and at the end of the suite is enough.
14363 Display only the children `times', not the shell's.
14364 If the test failed or was skipped, at-times is not available.
14366 2001-08-07 Akim Demaille <akim@epita.fr>
14368 Always produce testsuite.log, including when there are no
14369 failures. This helps getting information on skipped tests, and
14370 duration of the tests. Err, implement the latter btw.
14372 * lib/autotest/general.m4 (AT_INIT): Set up fd 6 for the log.
14373 Dump information on the first run of each test.
14374 (AT_CLEANUP): Create `at-times' containing the duration of the
14377 2001-08-07 Akim Demaille <akim@epita.fr>
14379 The use of `dumpstat' revealed that `len' was used although it
14380 should not. m4_text_wrap was using it, but in the Autoconf world
14381 where it is legal. Hence (i) test M4sh in its own world, not
14382 Autoconf's, and (ii), ahem, fix the bug :)
14384 * lib/autotest/general.m4: Be sure the set good quotes, as tracing
14385 does not like `' instead of [].
14386 (AT_INIT): Forbid `^_?AT_'.
14387 And don't output such tokens.
14388 * tests/Makefile.am (CLEANFILES): Add `script', `script.s4g',
14389 `script.as', and `autom4te.cache'.
14390 Remove `empty' and `macro' which are no longer used.
14391 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): New.
14392 * tests/m4sugar.at: Use it.

14412 2001-08-04 Akim Demaille <akim@epita.fr>
14414 Don't rely on M4sugar outputting the patterns in files, since we
14415 might process the output _without_ running m4, hence without these

14419 * bin/autom4te.in (@Request::includes): Remove, unused.
14420 (@Request::source): Rename as...
14421 (@Request::input): this.

14428 2001-08-04 Akim Demaille <akim@epita.fr>
14430 `autoconf && autoheader' is sped up. Now, speed up `autoheader &&
14431 autoconf', i.e., in addition to caching traces, cache the output.

14445 (&parse_args, &print_usage): -f, --force is a new option.

14447 (&parse_args): The first file only can be frozen.
14449 2001-08-04 Akim Demaille <akim@epita.fr>
14451 Don't let autom4te compute the `include' traces several times:
14452 first check that the trace cache file is up to date, and then
14453 compare its timestamp with that of the output.
14455 * bin/autom4te.in, bin/autoupdate.in, bin/autoscan.in: Normalize
14456 the preamble. Don't require 5.005 as Autom4te::General does it,
14457 and better yet (use `use', not `require'!).
14458 * lib/Autom4te/Struct.pm: Rename the last occurrences of
14459 Class::Struct as Autom4te::Struct.
14460 * lib/Autom4te/General.pm (File::stat): Use it.
14461 (&mtime): New, export it.
14462 * bin/autom4te.in: Use it.
14463 Declare `$req' is invalid if it is outdated.

14469 must be proposed to the users.

14516 * bin/autom4te.in (&handle_output): Remember of the first
14517 occurrence of a possibly undefined macro, not the last.

14521 * tests/tools.at (autoconf: forbidden tokens, basic)
14522 (autoconf: forbidden tokens, exceptions): No longer sort
14523 autoconf's stderr, as it is now deterministic.

14548 * bin/autoupdate.in (File::Compare, File::Copy): Use them instead of
