4104 Cover more potentially problemtic file names. Use the new
4107 Properly handle funny file names for headers in config.status.
4108 The test suite did not cover this bug because the code was not
4109 quoting properly the arguments of `rm -f' (which "fails" silently)
4110 as well as the arguments of `diff' (whose output was redirected to
4111 /dev/null so we couldn't see its error message).

4226 Add 'testsuite -C dir'.
4227 * lib/autotest/general.m4 (_AT_ARG_OPTION): Move missing argument
4229 (AT_INIT) <PARSE_ARGS_END>: ...here, since -k always takes
4231 <DEFAULTS>: Delay computation of variables based on $at_dir...
4232 <PREPARE_TESTS>: ...to here, since -C can change $at_dir.
4233 <TESTS>: Re-invoke via absolute name, since -C may be in effect.
4234 <PARSE_ARGS>: Parse new option.
4235 <HELP_TUNING>: Document it.

4251 * doc/autoconf.texi (Particular Programs): Do not mention the
4252 Autoconf version in which the AC_PROG_INSTALL change was done.

4257 Fix --help=recursive with multiple AC_CONFIG_SUBDIRS.
4258 * lib/autoconf/general.m4 (_AC_INIT_HELP): If, for recursive help
4259 mode, we change to the source directory, also set $ac_pwd so we
4260 do not go back to the build tree for the next config subdir.
4261 * tests/torture.at (Deep Package): Extend test to contain two
4262 config subdirs on the top level.
4264 Fix parallel `maintainer-check'.

4316 (m4_require): Use m4_do, not m4_join.
4318 Fix some whitespace tests on cygwin.

4323 * tests/local.at (AT_CHECK_M4): Cater to new m4 error message.
4325 Optimize AC_REQUIRE.

4338 * tests/base.at (Input/Output): Likewise.
4339 * tests/local.at (AT_CONFIGURE_AC): Copy install-sh,
4340 config.guess, and config.sub to test source tree.

4344 AC_CONFIG_AUX_DIR setting, copy install-sh to test source tree.
4345 (Substitute a newline, datarootdir workaround): Likewise.
4346 (Define a newline): Adjust for linenumber changes in configure.ac.

4356 * tests/m4sh.at (LINENO): Quote $0.
4358 Fix testsuite program wrapper for whitespace in `pwd`.
4359 The problem here is that the usual mantra is that command
4360 variables can contain arguments, thus we cannot just escape
4361 $AUTOCONF, $AUTOM4TE etc. The compromise is to put the
4362 $top_builddir/tests directory early in $PATH, so that the
4363 wrappers are found by their plain name.
4364 * tests/wrapper.as: Put $testdir early in $PATH.

4377 <at_func_create_debugging_script, Driver Loop>:
4378 Quote $at_group_dir.
4379 * tests/autotest.at (whitespace in absolute testdir): New test.
4381 * lib/autom4te.in: Quote @datadir@.
4383 Proper file name escaping in Autoconf programs and Perl modules.
4384 This includes escaping of characters special to the shell
4385 as well as special to Perl, e.g., leading `<' or `>'.
4386 For example, when $file starts with `>', `open ">$file"'
4387 wrongly tries to append to a different file.
4388 * bin/autoconf.as: Fix quoting for autom4te options.
4389 * lib/Autom4te/General.pm (shell_quote): New function, taken
4390 from coreutils, written by Jim Meyering.

4394 * bin/autoreconf.in (parse_args): Likewise.

4398 * bin/ifnames.in: Likewise, XFile usage fixes.
4399 * tests/tools.at (autom4te and whitespace in file names): Extend
4400 test. Test twice, with special characters allowed on w32, and the
4401 rest. Test leading and trailing whitespace, for `open_quote'.
4402 (autotools and whitespace in file names): New, analogous test.
4403 Reported by Paul Eggert and Benoit Sigoure, additional suggestions
4404 by Russ Allbery and Eric Blake.

4408 lib/Autom4te/Struct.pm, lib/Autom4te/XFile.pm: Likewise.
4409 * lib/Autom4te/FileUtils.pm (open_quote): New function.
4410 (update_file, contents): Use it.
4412 * Makefile.am (autom4te-update): Rewrite for git.
4414 2007-12-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4416 * doc/autoconf.texi (autom4te Invocation, Autom4te Cache): Fix typos.
4418 Fix copyright years.
4419 * Makefile.am, doc/install.texi, lib/autoconf/fortran.m4,
4420 lib/autoconf/lang.m4, lib/freeze.mk: Likewise.

4432 2007-11-27 Paul Eggert <eggert@cs.ucla.edu>
4434 Fix AC_C_BIGENDIAN bug caused by new awk method of substitution.
4435 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Don't comment out the
4436 #undef as this runs afoul of our new way of creating config.h.
4437 Problem reported by Jim Meyering in
4438 <http://lists.gnu.org/archive/html/autoconf-patches/2007-11/msg00164.html>.

4442 Fix autom4te for unusual characters in input file names.
4443 * bin/autom4te.in (files_to_options): Quote active characters

4454 `#AT_STOP_...' line at the end of each test.
4456 2007-11-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4458 * lib/autotest/general.m4 (AT_INIT): For awk line number
4459 extraction script, ensure `$at_group' has a defined value
4460 even for the empty set, and properly quote its usage inside
4463 2007-11-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4465 * doc/autoconf.texi (Shell Functions): New chapter. Document
4466 IRIX sh $0 issue in functions, move content from ...
4467 (Portable Shell): ... here.
4468 (Shell Script Compiler): Note that shell functions are not
4469 totally unportable any more.
4471 2007-11-22 Stepan Kasal <kasal@ucw.cz>
4472 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4474 * lib/autotest/general.m4 (AT_INIT): Exit awk script after
4475 extracting the line numbers of the last needed test.
4477 2007-11-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4479 * lib/autotest/general.m4 (AT_INIT) <at_func_create_debugging_script>:
4482 2007-11-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4484 Fix IRIX testsuite debugging failures: $0 in functions.
4485 * lib/autotest/general.m4 (AT_INIT) <at_func_create_debugging_script>:
4486 Do not use $0 inside a function, as IRIX sh will set that to the
4487 function name rather than the script invocation name.
4489 2007-11-19 Paolo Bonzini <bonzini@gnu.org>
4490 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4492 * lib/autotest/general.m4 (at_func_test): Use cached line numbers
4493 to extract test scripts.
4494 (AT_INIT): Extract and cache test script line numbers.
4496 2007-11-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4498 * lib/autotest/general.m4: Revert 2007-11-15 patch and
4499 subsequent fixups; the awk -> here-document conversion trashes
4500 performance too much with AIX sh.
4502 2007-11-18 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4504 * tests/local.at: Do not test m4, perl with AT_TESTED.
4506 Diagnose and guard against write errors dealing with config.status.
4507 The general idea is this: all write failures from `configure'
4508 writing `config.status' are indicated by $ac_write_error, which
4509 is only checked at the end. This is safe because config.status
4510 code is not executed before the file is complete. Other write
4511 failures, be they inside config.status, or in sub shell/awk
4512 scripts spawned from configure or config.status, typically need
4513 earlier checking, as their results are used right afterwards.
4514 * lib/autoconf/status.m4 (AC_OUTPUT): Initialize `ac_write_fail'
4515 before writing config.status, check afterwards.
4516 (_AC_OUTPUT_FILES_PREPARE, _AC_OUTPUT_FILE)
4517 (_AC_OUTPUT_HEADERS_PREPARE,_AC_OUTPUT_CONFIG_STATUS):
4518 Set `ac_write_error' for write failures to config.status. Barf
4519 upon write failures to temporary files.
4520 Adjust note about closing and reopening the here-document.
4521 (_AC_OUTPUT_HEADER, _AC_OUTPUT_LINK, _AC_OUTPUT_COMMAND)
4522 (_AC_OUTPUT_MAIN_LOOP): Likewise, adjust note about closing and
4523 reopening the here-document.
4524 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
4525 Ensure `ac_write_error' does not escape into config.status.
4526 Also, add a couple of code paths not yet exercised in the test
4527 suite: a config file with input from stdin, and a config header
4529 Suggestion for catching write errors by Bruno Haible.
4531 2007-11-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4533 Avoid error with Tru64 awk and testsuite lines with many words.
4534 * lib/autotest/general.m4 (AT_INIT): In the awk script that
4535 reads the testsuite, set the field separator to an unusual value,
4536 in order to not run over the limit of 199 fields. Tru64 4.0D awk
4537 even splits the input if $i, i>0, was never accessed in the script.
4539 Revert 2007-10-17 change.
4540 * TODO: Multiline args in config files and headers mean something
4541 different and are not fixed, see
4542 <http://lists.gnu.org/archive/html/autoconf-patches/2007-05/msg00017.html>
4543 Report by Stepan Kasal.
4545 * doc/autoconf.texi (Generic Programs): Fix typo.
4547 2007-11-16 Stepan Kasal <kasal@ucw.cz>
4549 AC_*_TOOL does not canonicalize the prefix
4550 * doc/autoconf.texi (Generic Programs): Do not say that
4551 the *_TOOL macros canonicalize, they simply use the `host_alias'.
4553 2007-11-16 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4555 Diagnose write errors in config.status instantiations.
4556 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE)
4557 (_AC_OUTPUT_HEADER, _AC_OUTPUT_MAIN_LOOP): Bail out
4559 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
4560 Extend test to also check for some write error failures, using...
4561 <AT_CHECK_CONFIG_CREATION_NOWRITE>: ...this new macro.
4562 Report by Bruno Haible.
4565 * lib/autotest/general.m4 (AT_INIT) <at_func_log_failure>: Fix
4567 (_AT_CHECK): Use less indentation, to save space.
4569 2007-11-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4571 Add witness macro for @top_build_prefix@ substitution.
4572 * lib/autoconf/status.m4 (_AC_HAVE_TOP_BUILD_PREFIX): New macro.
4573 (_AC_OUTPUT_FILE): Mention it here.
4575 2007-11-15 Paolo Bonzini <bonzini@gnu.org>
4576 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4578 * lib/autotest/general.m4 (at_func_test): Remove.
4579 (AT_INIT): Pre-extract test groups into separate files.
4580 (AT_CLEANUP): Source pre-extracted file instead of calling at_func_test.
4581 Remove at-test-source files together with the $at_group_dir.
4582 * tests/autotest.at (Long test source lines): New test.
4584 2007-11-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4586 Shell functions and variables may share a namespace.
4587 * doc/autoconf.texi (Portable Shell): Mention Solaris sh
4590 2007-11-14 Paul Eggert <eggert@cs.ucla.edu>
4592 * lib/autoconf/types.m4 (_AC_TYPE_LONG_LONG_SNIPPET): Make comment match
4595 2007-11-14 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4597 * lib/autoconf/status.m4: Fix a couple of comment typos.
4599 * lib/m4sugar/m4sh.m4 (AS_TMPDIR): Use $as_me, not $me.
4601 2007-11-13 Jim Meyering <meyering@redhat.com>
4603 Clean up the rule to create "expr".
4604 * tests/Makefile.am (expr): Don't redirect directly to target.
4605 Redirect just once, not for each echo statement.
4606 Use $@, not literal "expr".
4608 2007-11-13 Paul Eggert <eggert@cs.ucla.edu>
4610 Don't worry about preprocessor when testing long long.
4611 See: http://lists.gnu.org/archive/html/bug-gnulib/2007-11/msg00075.html
4612 * doc/autoconf.texi (Preprocessor Arithmetic): New section.
4613 (AC_TYPE_LONG_LONG_INT, AC_TYPE_UNSIGNED_LONG_LONG_INT):
4614 These no longer check for preprocessor flaws.
4615 * lib/autoconf/types.m4 (_AC_TYPE_LONG_LONG_SNIPPET):
4616 Do not check for preprocessor flaws.
4618 2007-11-13 Jim Meyering <meyering@redhat.com>
4620 Adapt dependencies, now that a version change doesn't modify configure.ac
4621 * GNUmakefile: Remove "make clean" kludge.
4622 * lib/m4sugar/Makefile.am (version.m4): Depend on Makefile, not
4624 Don't redirect directly to target.
4625 Use $@, not literal "version.m4".
4627 2007-11-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4629 * doc/autoconf.texi (Making testsuite Scripts): Document
4630 ":;{" shorthand as in previous patch.
4632 2007-11-12 Paul Eggert <eggert@cs.ucla.edu>
4634 * doc/autoconf.texi (Limitations of Builtins): Document problem
4635 with { ... } a bit more clearly. Suggest ":;{" as a shorthand
4637 * lib/m4sugar/Makefile.am (version.m4): Detect 'echo' failure.
4638 Use ":;{" shorthand.
4639 * tests/Makefile.am ($(srcdir)/package.m4): Likewise.
4641 2007-11-12 Jim Meyering <meyering@redhat.com>
4643 Add more non-srcdir build support.
4644 * GNUmakefile (dummy): Split a long line.
4645 Add -v option to autoreconf invocation.
4647 Remove the autoreconf-provided INSTALL, so that we regenerate it.
4648 * GNUmakefile (dummy): Remove INSTALL.
4650 Remove racy commands to build scripts in bin/ and tests/.
4651 * man/Makefile.am (.x.1): Now that scripts in bin/ and tests/
4652 are guaranteed to be built, remove the rules that tried to build
4653 them. Before, with a parallel build, these rules could lead to
4654 two processes writing tests/wrapper.in concurrently.
4656 Build in man/ only *after* building in bin/ and tests/.
4657 * Makefile.am (SUBDIRS): The man-page-creation process runs $(MAKE)
4658 in both bin/ and tests/.
4660 Accommodate non-srcdir build-from-checkout.
4661 * build-aux/git-version-gen: Require an additional parameter: $srcdir.
4662 Use git's --git-dir=$srcdir/.git option.
4663 Add quotes, in case tarball_version_file contains shell meta-characters.
4664 * GNUmakefile (_curr-ver): Pass $(srcdir) to git-version-gen.
4665 * configure.ac: Pass "." to git-version-gen.
4667 Avoid spurious test failures due to version skew.
4668 * GNUmakefile (dummy): Run $(MAKE) clean after autoreconf -i.
4670 2007-11-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4672 Avoid warnings about conftest.dSYM directories on Mac OS X Leopard.
4673 * lib/autoconf/general.m4 (_AC_LINK_IFELSE, _AC_RUN_IFELSE):
4674 Remove conftest.dSYM directory.
4675 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT)
4676 (_AC_LANG_PROGRAM_C_, _AC_FC_MAIN, __AC_FC_NAME_MANGLING):
4677 Remove `conftest.*' recursively.
4678 * lib/autoconf/lang.m4 (AC_LINK_IFELSE): Likewise.
4679 * lib/autoconf/specific.m4 (_AC_SYS_LARGEFILE_MACRO_VALUE):
4681 (_AC_COMPILER_OBJEXT_REJECT): Reject *.dSYM.
4683 Report and analysis by Jeff Squyres and Peter O'Gorman.
4685 2007-11-12 Benoit Sigoure <tsuna@lrde.epita.fr>
4687 Fix typos in variable names.
4688 * tests/semantics.at (test for AC_CHECK_LIB): s/at_m/ac_m/.
4690 2007-11-11 Benoit Sigoure <tsuna@lrde.epita.fr>
4692 Document that $((expression)) is not portable.
4693 * doc/autoconf.texi (Shell Substitutions): Here.
4695 2007-11-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4697 Ignore configure --help* errors due to LINENO-impaired shells.
4698 * tests/torture.at (Configuring subdirectories, Deep Package):
4699 In the --help* tests in read-only trees, make `.' temporarily
4700 writable again for the `stderr' file, and ignore errors due to
4701 the attempt to write configure.lineno.
4702 Report by Patrick Welche.
4704 2007-11-10 Jim Meyering <meyering@redhat.com>
4706 Generate package.m4 in build-dir, not srcdir.
4707 * tests/Makefile.am (package.m4): Adjust target.
4708 Don't redirect directly to $@.
4709 (CLEANFILES): Add package.m4.
4710 ($(TESTSUITE)): Depend on just-built package.m4, not the one
4712 When running $(AUTOTEST), search "." before searching $(srcdir).
4714 Avoid a race condition that would make parallel "distclean" fail.
4715 * tests/Makefile.am (distclean-generic): Replace the default,
4716 automake-provided rule with an identical one, but with an additional
4717 dependency on distclean-local. Simply adding the dependency would
4718 cause automake not to emit the rule at all.
4719 * BUGS: Building with -jN works, now.
4721 Distribute git-version-gen.
4722 * Makefile.am (EXTRA_DIST): Add build-aux/git-version-gen,
4723 since GNUmakefile is distributed, and requires it for dist* rules.
4725 Remove two more generated files from version control.
4726 * INSTALL: Remove generated file.
4727 * lib/autoscan/autoscan.list: Remove generated file.
4729 2007-11-09 Paul Eggert <eggert@cs.ucla.edu>
4731 * GNUmakefile (PATH): Remove stray apostrophes; they become
4732 part of PATH, which isn't wanted here.
4734 2007-11-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4736 New config files output variable `top_build_prefix'.
4737 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Substitute
4739 * doc/autoconf.texi (Preset Output Variables): Document it.
4741 Report by Bob Friesenhahn.
4743 Avoid expr for arithmetic evaluation if the shell accepts $((...)).
4744 * lib/autotest/general.m4 (AT_INIT) <at_func_arith>: New
4745 function, to parametrize arithmetic with expr vs. the shell.
4746 Use it where possible.
4747 Suggestion by Benoit Sigoure.
4749 2007-11-03 Benoit Sigoure <tsuna@lrde.epita.fr>
4751 Adjust the documentation of autotest WRT atlocal.
4752 * doc/autoconf.texi (Making testsuite Scripts): It is not necessary,
4753 when using Automake, to write a rule to produce atlocal, since it's
4754 an AC_CONFIG_FILES. Mention that atlocal.in needs to be
4755 distributed, not atconfig.in.
4757 2007-11-04 Eric Blake <ebb9@byu.net>
4759 Update list information.
4760 * README: Mention new autoconf-commit list.
4761 * doc/autoconf.texi (Introduction): Mention autoconf-commit list.
4763 2007-11-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4765 * lib/autoconf/functions.m4 (_AC_FUNC_MALLOC_IF): Fix comment typo.
4767 * lib/m4sugar/Makefile.am (version.m4): Another bash bug workaround.
4769 * build-aux/.gitignore: Ignore mkinstalldirs.
4771 * doc/autoconf.texi (autoreconf Invocation): Fix an underfull line.
4773 2007-11-03 Jim Meyering <meyering@redhat.com>
4775 s/-/./ in snapshot version string: 2.61a-256-8b556 -> 2.61a.256-8b556
4776 * build-aux/git-version-gen: This syncs from coreutils.
4778 Adjust the build procedure so "make check" works reliably.
4779 * README-hacking: Include an extra step between "make" and
4780 "make check" to ensure that the latter passes.
4782 Use just-built tools, when possible.
4783 * GNUmakefile (PATH): Set and export here, ...
4784 (dummy): ... rather than here.
4786 2007-11-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4787 and Andreas Schwab <schwab@suse.de>
4789 * tests/Makefile.am ($(srcdir)/package.m4): Work around bash
4792 2007-11-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4794 * configure.ac (AC_PREREQ): Require version 2.60, for
4795 AC_PROG_SED, AC_PROG_GREP.
4797 2007-11-02 Benoit Sigoure <tsuna@lrde.epita.fr>
4798 and Jim Meyering <meyering@redhat.com>

4800 and Eric Blake <ebb9@byu.net>
4802 Document a bug in GNU Bash with compound commands and redirections.

4807 2007-11-03 Eric Blake <ebb9@byu.net>
4809 Support m4 1.4.5 in testsuite.
4810 * tests/torture.at (Define a newline): Exclude line numbers in
4812 Reported by Ralf Wildenhues.
4814 2007-11-03 Jim Meyering <meyering@redhat.com>
4816 Remove automake-provided files from version control.
4817 * build-aux/elisp-comp: Remove file.
4818 * build-aux/install-sh: Remove file.
4819 * build-aux/missing: Remove file.
4820 * build-aux/mdate-sh: Remove file.
4821 * build-aux/.gitignore: New file.
4822 Suggestion from Ralf Wildenhues.
4824 2007-11-03 Eric Blake <ebb9@byu.net>
4826 Adjust version comparison to account for git snapshot numbers.
4827 * lib/m4sugar/m4sugar.m4 (_m4_version_unletter): Also treat - as a
4828 component separator.
4829 * doc/autoconf.texi (Number processing Macros)
4830 <m4_version_compare>: Document this change.
4831 * tests/m4sugar.at (m4@&t@_version_compare): Test it.
4833 2007-10-30 Bruno Haible <bruno@clisp.org>
4835 * lib/autoconf/types.m4 (_AC_TYPE_LONG_LONG_SNIPPET): New macro,
4836 extracted from AC_TYPE_LONG_LONG_INT and AC_TYPE_UNSIGNED_LONG_LONG_INT.
4837 (AC_TYPE_LONG_LONG_INT, AC_TYPE_UNSIGNED_LONG_LONG_INT): Use it.
4838 Fixes problem with Sun C 5.[0-8] in 32-bit mode, reported in
4839 <http://lists.gnu.org/archive/html/autoconf-patches/2007-10/msg00210.html>
4840 Suggested by Paul Eggert.
4842 2007-10-28 Jim Meyering <meyering@redhat.com>
4844 * README-hacking: Autoconf, Automake, and Perl are required to build.
4845 List Gzip and Tar separately. Suggested by Ralf Wildenhues.
4847 2007-10-28 Jim Meyering <meyering@redhat.com>
4849 README-hacking: Recommend running autoreconf -vi.
4850 * GNUmakefile (dummy): Use autoreconf -i, with appropriate PATH,
4851 so that we use just-built tools when they're available.
4852 Suggestions from Ralf Wildenhues.
4854 2007-10-28 Jim Meyering <meyering@redhat.com>
4856 Make inter-release --version output more useful.
4858 Now, each unofficial build has a version "number" like 2.61a-19-58dd,
4859 which indicates that it is built using the 19th change set
4860 (in _some_ repository) following the "v2.61a" tag, and that 58dd
4861 is a prefix of the commit SHA1.
4862 * build-aux/git-version-gen: New file.
4863 * configure.ac: Run it to set the version.
4864 (AM_INIT_AUTOMAKE): Don't check NEWS here.
4865 * Makefile.am (dist-hook): Arrange so that .version appears only
4866 in distribution tarballs, never in a checked-out repository.
4867 * .gitignore: Add .version here, too. Just in case.
4868 * tests/Makefile.am ($(srcdir)/package.m4): Depend on Makefile,
4869 not configure.ac, now that the version number changes automatically.
4871 Ensure that $(VERSION) is up to date for dist-related targets.
4872 * GNUmakefile: Arrange to rerun autoconf, if the version reported by
4873 git-version-gen doesn't match $(VERSION), but only for dist targets.
4875 2007-10-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

4886 * Makefile.in: Remove, along with all other Makefile.in in subdirs.
4887 * .gitignore: Add aclocal.m4, configure and Makefile.in. Sort.
4888 * README-hacking: New file: how to build from just-checked-out sources.
4890 2007-10-23 Eric Blake <ebb9@byu.net>
4892 Improve corner case of m4_expand.
4893 * lib/m4sugar/m4sugar.m4 (m4_expand, _m4_expand): Rewrite more
4895 * tests/m4sh.at (AS@&t@_HELP_STRING): Test overquoted comma.
4896 * doc/autoconf.texi (Evaluation Macros) <m4_expand>: Update
4899 2007-10-23 Paul Eggert <eggert@cs.ucla.edu>

4910 2007-10-22 Eric Blake <ebb9@byu.net>
4912 * doc/autoconf.texi (Particular Types): Mention bug in HP-UX 11.00
4915 2007-10-22 Paul Eggert <eggert@cs.ucla.edu>
4917 Don't check for bug in HP-UX 11.00 cpp.
4918 * lib/autoconf/types.m4 (AC_TYPE_UNSIGNED_LONG_LONG_INT):
4919 Use -1ull rather than -1u, since that causes problems with gnulib; see
4920 <http://lists.gnu.org/archive/html/bug-gnulib/2007-10/msg00329.html>.

4938 escaping of backslash in here-documents.
4940 Fix `Deep Package' test failure on FreeBSD.
4941 * tests/torture.at (Deep Package): Do not add `.' to $PATH
4942 unnecessarily. Do not try running `/bin/sh configure' with a
4943 configure script to be found in $PATH, if the shell does not do
4944 this resolution. Fixes test failure on FreeBSD.
4946 Fix config header generation with AIX awk.

6024 * lib/autoconf/c.m4 (AC_OPENMP): Don't echo --enable-openmp

6129 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't look

6144 AC_CHECK_TYPE, AC_CHECK_TYPES.
6145 * doc/autoconf.texi (Generic types): C types must be type-names
6146 (the C terminology), not type-ids (the C++ term). C++ types
6147 must not be anonymous.
6148 * lib/autoconf/types.m4 (_AC_CHECK_TYPE_NEW): Remove special case
6149 for C++; this drops support for anonymous struct and union types,
6150 which were problematic anyway.

6170 Document the restrictions on AC_CHECK_ALIGNOF's type argument.
6171 * lib/autoconf/types.m4 (_AC_CHECK_TYPE_NEW):
6172 For C, just try sizeof (TYPE) and sizeof ((TYPE)); if the former
6173 works but the latter doesn't, then it's a valid type.
6174 This lets people use function types and so forth.
6175 For C++ there doesn't seem to be a simple solution, so leave it alone.
6176 (AC_CHECK_SIZEOF): Allow argument to be a variable.
6177 (AC_CHECK_SIZEOF, AC_CHECK_ALIGNOF): Don't bother to invoke
6178 AC_CHECK_TYPE; that wasn't documented or necessary.

6231 nonstandard grep R.E. escape sequences.
6233 2007-03-17 Jim Meyering <jim@meyering.net>
6235 * doc/autoconf.texi: Adjust grammar around use of "heuristics".
6236 (Limitations of Usual Tools): Also list \< and \>, and mention that
6237 HP-UX's grep, like the one from Solaris, does not support that syntax.
6239 2007-03-09 Stepan Kasal <kasal@ucw.cz>
6241 * doc/autoconf.texi (Specifying Names): `--host' does not
6242 change the build type.

6349 AC_SUBST([MKDIR_P]), so that Automake < 1.10 will pick up its
6350 trace, if a package uses AC_PROG_MKDIR_P explicitly. The actual
6351 substitution will still be done by the special code.
6352 Report by Jim Meyering.
6354 * doc/autoconf.texi (File System Conventions): Mention that
6355 $PATH_SEPARATOR is for the build system only.

6433 2006-12-28 Steven G. Johnson <stevenj@alum.mit.edu>
6435 * lib/autoconf/general.m4 (AC_DEFINE_TRACE): Don't include
6436 preprocessor macro arguments in traced name.
6437 * doc/autoconf.texi (Defining symbols): Document longstanding
6438 support for AC_DEFINE-ing macros with arguments, and document
6439 behavior when the same variable has multiple AC_DEFINEs.
6440 * lib/autoconf/fortran.m4 (_AC_FC_WRAPPERS): Revert to the
6441 old implementation which AC_DEFINEs the FC_FUNC and FC_FUNC_
6442 macros directly, giving much shorter and simpler code.
6444 2006-12-28 Malcolm Purvis <malcolmp@xemacs.org> (trivial change)
6446 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Insert a
6447 space before "$ac_configure_args" to prevent a 'config.status
6448 --recheck' failure if ac_configure_args doesn't contain a leading
6449 space. This works around a problem with the XEmacs configure.ac,
6450 which uses the (undocumented) ac_configure_args variable
6451 inconsistently with Autoconf.
6453 2006-12-22 Paul Eggert <eggert@cs.ucla.edu>
6455 * lib/autoconf/functions.m4 (AC_FUNC_MKTIME):
6456 Include <limits.h>, and use its INT_MAX to rewrite the
6457 j loop so that it does not overflow 'int'. Problem reported by
6459 <http://lists.gnu.org/archive/html/bug-gnulib/2006-12/msg00084.html>.
6460 Play it safe by shifting left by 1 rather than multiplying by 2,
6461 as GCC is less likely to optimize this away when the value
6462 is signed (when it assumes overflow leads to undefined behavior).
6463 Also, don't assume time_t uses two's complement.
6465 2006-12-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6467 * tests/torture.at (Substitute a 2000-byte string): Avoid using
6468 a 10kB long (multi-line) string literal, OpenServer 5.0.7 ksh
6469 dumps core on it. Report by Tim Rice.
6471 2006-12-18 Steven G. Johnson <stevenj@alum.mit.edu>
6473 * lib/autoconf/general.m4 (AC_ARG_ENABLE): Print help about
6474 --disable-option-checking to --help output even when
6475 AC_PRESERVE_HELP_ORDER is not used.
6476 (_AC_INIT_PARSE_ENABLE2): Print warnings using actual --enable or
6477 --with argument, rather than argument with [-.] replaced by
6479 * NEWS: Fix typo in previous change; the news was in the
6482 2006-12-18 Paul Eggert <eggert@cs.ucla.edu>
6484 * NEWS: Warnings are now generated by default for unknown
6485 --enable-* and --with-* options.
6486 * doc/autoconf.texi (Option Checking): Renamed from
6487 (Configure Option Checking). Tighten up the wording a bit.
6488 (External Software, Package Options): Cross-reference to Option
6489 Checking, and use this to shorten our section.
6490 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Prefer test -n
6491 "$x" to test "x$foo" != x.
6492 * lib/autoconf/status.m4 (AC_OUTPUT): Likewise.
6493 Don't warn if $enable_option_checking is "no".
6494 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Initialize
6495 ac_unrecognized_opts to the empty string.
6496 Don't echo the unrecognized opts, as this might mishandle
6497 backslashes or leading -.
6498 (AC_PRESERVE_HELP_ORDER): Put the --disable-option-checking
6499 usage next to the other --disable-FEATURE options in the
6502 2006-12-18 Steven G. Johnson <stevenj@alum.mit.edu>
6504 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS, _AC_INIT_PARSE_ARGS):
6505 (_AC_INIT_PARSE_ENABLE2, _AC_INIT_HELP, _AC_ENABLE_IF):
6506 Print warning for unrecognized --with and --enable options
6507 (AC_DISABLE_OPTION_CHECKING): New macro to disable warnings.
6508 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS, _AC_OUTPUT_SUBDIRS):
6509 Disable option checking when subdirs are configured.
6510 (AC_OUTPUT): If warnings are enabled, print warning about
6511 unrecognized --with and --enable options at the end of
6512 the configure output (as well as at the beginning).
6513 * doc/autoconf.texi (Option Checking): New node.
6514 Document new option warning functionality.
6516 2006-12-16 Eric Blake <ebb9@byu.net>
6518 * configure.ac (AC_INIT): Bump version, since 2.61a is released.
6519 * NEWS: Start news for current version.
6521 2006-12-15 Paul Eggert <eggert@cs.ucla.edu>
6523 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT):
6524 Define HAVE_GETMNTENT to 1, not to the empty string.
6525 Problem originally reported by Jochen Friedrich in
6526 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=403243>.
6528 This change prompted by a problem report by Andrey Simonenko in
6529 <http://lists.gnu.org/archive/html/bug-autoconf/2006-12/msg00026.html>.
6530 * doc/autoconf.texi (Defining Symbols): AC_DEFINE works for
6531 object-like macros only, in the traditional portable character
6533 * lib/autoconf/general.m4 (AC_DEFINE_TRACE_LITERAL):
6534 Warn about attempts to define things that are not identifiers.
6535 * lib/autoconf/fortran.m4 (_AC_FC_WRAPPERS): Rewrite to avoid
6536 awful hack that AC_DEFINEd macro names containing parentheses.
6538 2006-12-12 Paul Eggert <eggert@cs.ucla.edu>
6540 * doc/autoconf.texi: Undo some of the 2006-12-10 change. It was
6541 too drastic, even if Texinfo in theory requires it for info mode.
6543 (config.status Invocation): Renamed back from Recreating a
6545 (Obsolete config.status Use): Renamed back from Obsolete Recreation.
6546 (Autoconf 2.13): Renamed back from 20th-century Autoconf 2.
6548 2006-12-11 Paul Eggert <eggert@cs.ucla.edu>
6550 * NEWS: Version 2.61a.
6552 2006-12-11 Paul Eggert <eggert@cs.ucla.edu>
6553 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6555 * NEWS: Document changes with echo and printf, and the lack
6556 of limits on the total size of multi-line values of substituted
6557 variables, and the AC_FUNC_FSEEKO fix.
6559 2006-12-10 Paul Eggert <eggert@cs.ucla.edu>
6561 * doc/autoconf.texi (Writing Autoconf Input): Renamed from
6562 Writing configure.ac.
6563 (Autoconf Input Layout): Renamed from configure.ac Layout.
6564 (Recreating a Configuration): Renamed from config.status Invocation.
6565 (Obsolete Recreation): Renamed from Obsolete config.status Use.
6566 (acconfig Header): Renamed from acconfig.h.
6567 (20th-century Autoconf 2): Renamed from Autoconf 2.13.
6568 (Writing Testsuites): Renamed from Writing testsuite.at.
6569 (Autom4te Cache): Renamed from autom4te.cache.
6571 * BUGS: Remove mention of VPATH problem, since it's now documented
6572 not to be a bug in the Autoconf build procedure itself, but rather
6573 a problem with the proprietary `make' programs.
6575 * doc/autoconf.texi (Build Directories): Add a cross reference
6578 * build-aux/config.guess, build-aux/config.sub, build-aux/texinfo.tex:
6579 * doc/standards.texi: Sync from gnulib.
6581 * man/autoconf.1, man/autoheader.1, man/autom4te.1, man/autoreconf.1:
6582 * man/autoscan.1, man/autoupdate.1, man/config.guess.1:
6583 * man/config.sub.1, man/ifnames.1: Remove from CVS, since they're
6584 generated automatically.
6586 2006-12-06 Paul Eggert <eggert@cs.ucla.edu>
6588 * lib/autoconf/c.m4 (_AC_PROG_CC_C89): Also try -xc99=all, for Sun
6589 C 5.8 on Solaris 10. Using -xc99=all rather than -xc99 bypasses
6590 the buggy -xc99 option of Forte Developer 7 C on Solaris 9.
6592 2006-12-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6594 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Drop the
6595 `CEOF$ac_eof' special marker, the awk script cannot contain a
6596 line matching `^CEOF', so this is not needed any more.
6597 * tests/torture.at (Substitute a newline): Expose the `%!_!# '
6598 special marker in the test.
6600 2006-12-06 Stepan Kasal <kasal@ucw.cz>
6602 * tests/tools.at (autom4te preselections): Use `find -newer';
6603 remove one of the sleeps.
6605 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE): Make it
6606 more readable, using ...
6607 (_AC_INIT_PARSE_ENABLE2): ... this new helper macro.
6609 * doc/autoconf.texi (autoheader Invocation): Do not double-
6610 quote the parameter of `AH_BOTTOM' in the example.
6612 2006-12-05 Stepan Kasal <kasal@ucw.cz>
6614 * doc/autoconf.texi (Configuration Headers): Remove the
6615 example with multiple input files.
6616 (autoheader Invocation): Encourage `AH_BOTTOM', discouraging
6617 multiple input files.
6619 2006-12-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6621 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): When
6622 creating the awk substitution script, handle one input line at a
6623 time, so that the maximum length of a substituted (multi-line)
6624 value is not limited by the size of the sed pattern space.
6625 The trade-off is a slightly repetitive sed script.
6626 * doc/autoconf.texi (Limitations of Usual Tools): Branch labels
6627 can only have up to 7 characters, due to Solaris 10 /bin/sed.
6628 * tests/torture.at (Substitute a 2000-byte string): Increase the
6629 test with several long lines, they should not be caught by sed
6632 * tests/tools.at (autom4te preselections): New test, to flag
6633 entries missing from autom4te.cfg.
6634 Report by David Byron <dbyron@hheld.com>.
6636 * tests/torture.at (Substitute a 2000-byte string): Actually use
6637 AC_PROG_AWK, so the last change works as intended.
6638 (Substitute and define special characters): Likewise.
6639 (Substitute a newline): Likewise.
6641 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Use `$AWK'
6642 instead of `awk' consistently.
6643 (_AC_OUTPUT_CONFIG_STATUS): Initialize $AWK.
6644 * tests/torture.at (Torturing config.status): Test both the
6645 result of AC_PROG_AWK and plain awk.
6646 (Substitute a 2000-byte string): Likewise.
6647 (Substitute and define special characters): Likewise.
6648 (Substitute a newline): Likewise.
6650 2006-12-04 Paul Eggert <eggert@cs.ucla.edu>
6652 * lib/autoconf/functions.m4 (AC_FUNC_FSEEKO): Check that fseeko
6653 can be assigned to a function pointer. Problem reported by
6654 Peter Palfrader in <http://bugs.debian.org/401377>. Based on
6655 part of a patch by Ralf Wildenhues in that same bug report.
6657 2006-12-01 Paul Eggert <eggert@cs.ucla.edu>
6659 * tests/mktests.sh (ac_exclude_list): Exclude AC_FUNC_SETVBUF_REVERSED.
6660 * tests/semantics.at (AC_FUNC_SETVBUF_REVERSED): New test.
6662 2006-12-01 Eric Blake <ebb9@byu.net>
6664 * lib/autoconf/c.m4 (AC_LANG_INT_SAVE): Avoid newline, to aid in
6665 cross-compiling from cygwin to mingw.
6666 Reported by Bob Rossi. This resurrects the 2000-11-30 patch to
6667 aclang.m4, which was mistakenly removed in the 2001-09-17 patch
6668 to lib/autoconf/c.m4.
6670 2006-12-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6672 * lib/m4sugar/m4sh.m4 (_AS_ECHO_PREPARE): Use a longer test
6673 string for more reliable failure. Wrap the entire test that
6674 causes the broken Solaris printf to dump core, in a subshell,
6675 so the segmentation fault message is reliably suppressed.
6676 Fix shell expansion errors by using /usr/ucb/echo always;
6677 avoid an error on systems without it by another subshell.
6678 Avoid m4 expansion of `$1'. Set the zeroth argument of the
6679 subshell-$as_echo to `as_echo', for better error message.
6681 2006-11-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6683 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): If `BASH_ARGV' or
6684 `BASH_SOURCE' contain a newline, set them to empty, as they may
6687 2006-11-27 Paul Eggert <eggert@cs.ucla.edu>
6689 Turn AC_FUNC_SETVBUF_REVERSED into a noop. It's been obsolete for
6690 years and is too hard to maintain now. The last straw was
6691 reported by Jerker Baeck in
6692 <http://lists.gnu.org/archive/html/autoconf/2006-11/msg00102.html>.
6693 * NEWS: AC_FUNC_SETVBUF_REVERSED is now obsolete.
6694 * doc/autoconf.texi (Particular Functions): Move
6695 AC_FUNC_SETVBUF_REVERSED from here...
6696 (Obsolete Macros): ... to here. Say that it does nothing now.
6697 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
6698 Turn into (almost) a no-op.
6700 * lib/autoconf/c.m4 (AC_PROG_GCC_TRADITIONAL, AC_C_CONST):
6702 Do not recommend via AN_FUNCTION, AN_IDENTIFIER, or AN_HEADER.
6703 These macros are obsolescent and new applications shouldn't need them.
6704 * lib/autoconf/functions.m4 (AC_FUNC_CLOSEDIR_VOID, AC_REPLACE_FNMATCH):
6705 (AC_FUNC_GETLOADAVG, AC_FUNC_GETPGRP, AC_FUNC_MEMCMP):
6706 (AC_FUNC_SELECT_ARGTYPES, AC_FUNC_SETPGRP, AC_FUNC_STAT, AC_FUNC_LSTAT):
6707 (AC_FUNC_STRFTIME, AC_FUNC_SETVBUF_REVERSED, AC_FUNC_UTIME_NULL):
6708 (AC_FUNC_VPRINTF): Likewise.
6709 * lib/autoconf/headers.m4 (AC_HEADER_DIRENT, AC_HEADER_STAT):
6710 (AC_HEADER_STDC, AC_HEADER_SYS_WAIT, AC_HEADER_TIME): Likewise.
6711 * lib/autoconf/types.m4 (AC_STRUCT_TM): Likewise.
6713 * doc/autoconf.texi (Setting Output Variables): Mention that
6714 @VAR1@VAR2 has unspecified behavior. Problem reported by
6716 * NEWS: Mention this.
6718 * Makefile.am: Put only a single '#' into the copyright notice,
6719 so that it's also present in the output file. Standardize wording
6720 in makefile copyright notices to match GNU coding standards.
6721 * bin/Makefile.am: Likewise.
6722 * doc/Makefile.am: Likewise.
6723 * lib/Makefile.am: Likewise.
6724 * lib/freeze.mk: Likewise.

6729 * man/Makefile.am: Likewise.
6730 * tests/Makefile.am: Likewise.
6731 * lib/emacs/Makefile.am: Remove copyright notice; it's just a
6734 2006-11-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6736 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Fix error
6737 in the sed script that mangles the awk script: delete up to the
6738 first exclamation mark only.
6739 * tests/torture.at (Substitute and define special characters):
6742 2006-11-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6744 Rewrite config files generation: avoid quadratic growth in
6745 the number of substituted variables by using awk instead of sed
6746 for the bulk of the substitutions.
6747 * NEWS: Mention this.
6748 * doc/autoconf.texi (Setting Output Variables): `|#_!!_#|' is also
6749 forbidden in the output (and thus input) file.
6750 * lib/autoconf/status.m4 (_AC_AWK_LITERAL_LIMIT): New macro.
6751 (_AC_OUTPUT_FILES_PREPARE): Instead of several sed scripts,
6752 generate just one large awk script for substitutions,
6753 eliminating much of the earlier complexity, while adding some
6754 new complexity. Only expand the substitution templates at
6755 configure time, for smaller configure script size. If
6756 _AC_SUBST_FILES are used, test 'awk' for working getline support
6757 at config.status time. If absent, interpolate through the
6758 shell. The awk script was written with much help
6759 from Paolo Bonzini and Paul Eggert.
6760 (_AC_SED_CMD_NUM, _AC_SED_DELIM_NUM, _AC_SED_FRAG): Removed.
6761 (_AC_SED_FRAG_NUM): Likewise.
6762 (_AC_SUBST_CMDS): Renamed from...
6763 (_AC_SED_CMDS): ...this.
6764 (_AC_OUTPUT_FILE): Use _AC_SUBST_CMDS.
6765 * tests/torture.at (Substitute a 2000-byte string): Also
6766 substitute a line with 1000 words, and a variable with several
6768 (Substitute and define special characters): Test awk special
6769 characters, and put substitution input strings `@foo@' in the
6770 output, to test that no recursion happens; test several other
6771 combinations from Paolo Bonzini.
6773 2006-11-25 Paul Eggert <eggert@cs.ucla.edu>
6775 * lib/autotest/general.m4 (AT_INIT): Undo recent changes
6776 that replaced echo with AS_ECHO where this wasn't necessary.
6777 Problem reportd by Ralf Wildenhues.
6778 * lib/m4sugar/m4sh.m4 (_AS_ECHO_PREPARE): Port to Solaris 7,
6779 where "/usr/bin/printf '%s\n' S" dumps core if S is long.
6780 This is Sun bug 4206210. Problem reportd by Ralf Wildenhues.
6782 2006-11-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6784 * lib/freeze.mk (GREP): Removed, no need to initialize this.
6786 2006-11-21 Paul Eggert <eggert@cs.ucla.edu>
6788 * doc/autoconf.texi (Limitations of Usual Tools): Don't claim
6789 that traditional Awk lacks 3-arg "split". It has it.
6790 Mention that FS must be a single character, and a few other
6791 99-byte limits of traditional Awk.
6792 Mention that if (i in a) doesn't work with traditional Awk.
6794 2006-11-18 Paul Eggert <eggert@cs.ucla.edu>
6796 * tests/autotest.at (BSx641-newline in command):
6797 (BS-BS-newline in command, BSx640-newline in command):
6798 (Newline-CODE-BS-newline in command):
6799 (Single-quote-BS-newline in command):
6800 (Single-quote-newline-BS-newline in command):
6801 Use printf '%s\n' instead of echo, for portability to hosts
6802 where echo interprets backslashes. This will break on hosts
6803 that lack printf, but for now let's assume all such hosts
6804 are dead (if not, we should get reports of test failures).
6806 2006-11-17 Paul Eggert <eggert@cs.ucla.edu>
6808 'echo' has some portability problems, when given a first argument
6809 with a leading '-', or when given any argument containing '\'.
6810 Avoid using 'echo' in these cases.
6811 * bin/Makefile.am $(bin_SCRIPTS): Rewrite to avoid 'echo' entirely.
6812 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX, AC_PROG_OBJC): Likewise.
6813 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
6814 * lib/autotest/general.m4 (AT_INIT): Likewise.
6815 * bin/autoconf.as: Use AS_ECHO rather than plain echo, when the
6816 argument might be unportable.
6817 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Likewise.
6818 * lib/autoconf/erlang.m4 (AC_LANG(Erlang)): Likewise.
6819 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT):
6820 (_AC_FC_LIBRARY_LDFLAGS): Likewise.

6822 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE, _AC_INIT_PREPARE):
6823 (_AC_ARG_VAR_VALIDATE, AC_ARG_PROGRAM, _AC_MSG_LOG_CONFTEST):
6824 (AC_RUN_LOG, _AC_RUN_IFELSE, _AC_LIBOBJS_NORMALIZE): Likewise.

6834 (_AS_BASENAME_SED, _AS_DIRNAME_SED, AS_MKDIR_P, AS_TMPDIR, AS_UNAME):
6835 (AS_TR_SH, AS_TR_CPP, AS_VAR_GET): Likewise.
6836 * bin/autoconf.as: Redo verbose flag implementation, as the old
6837 scheme wouldn't work with AS_ECHO.
6838 * lib/autotest/general.m4 (AT_INIT): Likewise.
6839 * lib/autoconf/general.m4 (AC_MSG_RESULT, AC_MSG_RESULT_UNQUOTED):
6840 Don't use ECHO_T, since ECHO_N is now reliable.
6841 * lib/autotest/general.m4 (AT_INIT): Likewise.
6842 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Use sed "$script"
6843 rather than using a here-document to put the script into a file.
6844 (_AC_DO_ECHO): Hoist the eval out of the echo, so that we can
6846 * lib/m4sugar/m4sh.m4 (AS_VAR_GET): Likewise.
6847 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Use
6848 AS_ECHO_N rather than ECHO_N and ECHO_C. This doesn't fix any
6849 bug, but we might as well stop using ECHO_N and ECHO_C internally.
6850 * lib/autotest/general.m4 (AT_SETUP): Likewise.
6851 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N): Likewise.
6852 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
6853 (_AC_OUTPUT_MAIN_LOOP): Rework echo so that it has just one
6854 operand, as AS_ECHO requires. Avoid double file name expansion.
6855 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Invoke _AS_ECHO_PREPARE.
6856 Don't set as_nl, since _AS_ECHO_PREPARE does that now.
6857 (_AS_PREPARE): Comment that _AS_ECHO_N_PREPARE is just for user code.
6858 (AS_ECHO, AS_ECHO_N, _AS_ECHO_PREPARE): New macros.

6962 and non-portable sed scripts, and use $CONFIG_SHELL when invoking
6965 2006-11-08 Paul Eggert <eggert@cs.ucla.edu>
6967 * lib/autoconf/types.m4 (AC_TYPE_LONG_LONG_INT): Set
6968 ac_cv_type_long_long_int to 'yes' instead of 'cross-compiling'.
6969 Imported from a similar patch to gnulib by Bruno Haible.

7000 Single-quote in a test title,
7001 Double-quote in a test title): Don't expect failure anymore.
7002 (Backslash in a test title): Put a non-whitespace character after the
7003 backslash so that Bourne shells might actually see it as an escape
7005 (Brackets in a test title,
7006 Pound in a test title,
7007 Comma in a test title,
7008 Quoted Macro in a test title,

7012 Macro with double-quote in a test title,
7013 Macro with backslash in a test title): New tests expected to fail.
7014 * tests/torture.at (#define header templates): M4-quote this title in
7015 AT_SETUP call so that no M4 code is commented inadvertently somewhere.
7016 The visible effect was a stray [] in the testsuite output.
7018 2006-10-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7020 * doc/autoconf.texi (Limitations of Builtins): Do not invoke
7021 `trap ... 0' inside a function, for AIX sh.
7023 2006-10-26 Paul Eggert <eggert@cs.ucla.edu>
7025 * tests/base.at (AC_COMPUTE_INT): Test **0** rather than 1 / 0,
7026 since powerpc-apple-darwin8-gcc-4.0.1 (Apple Computer, Inc. build
7027 5363) simply issues a warning when dividing by zero at compile
7028 time. Problem reported by Elias Pipping.
7030 2006-10-26 Eric Blake <ebb9@byu.net>
7033 * doc/autoconf.texi (Evaluation Macros): Improve the example to
7034 show effect on macros that expand with commas.

7059 2006-10-24 Paul Eggert <eggert@cs.ucla.edu>
7061 * lib/autoconf/specific.m4 (_AC_SYS_LARGEFILE_MACRO_VALUE):
7062 If FUNCTION-BODY is nonempty, use AC_LINK_IFELSE rather than
7063 AC_COMPILE_IFELSE, to work around problem with OSF/1 4.0F fseeko
7064 reported by Nelson H. F. Beebe for Coreutils 6.4.
7066 * tests/tools.at (autoconf --trace: user macros): Remove test
7067 for tracing multiline macros, since m4 1.4.7a uses a different
7068 way to number lines. Problem reported by Ralf Wildenhues.
7070 2006-10-24 Stepan Kasal <kasal@ucw.cz>

7095 * doc/autoconf.texi (Caching Results): Likewise.
7096 * lib/autoconf/general.m4 (_AC_CACHE_CHECK_INT): Renamed from
7097 AC_CACHE_CHECK_INT, since it's no longer public.
7098 * lib/autoconf/types.m4: All uses of AC_CACHE_CHECK_INT changed.
7099 * tests/base.at (AC_COMPUTE_INT): Test this, not AC_CACHE_CHECK_INT.

7129 * lib/m4sugar/m4sh.m4 (AS_LITERAL_IF): Expand $1 before
7130 looking for special shell characters.
7131 * lib/autoconf/functions.m4 (AC_CHECK_FUNC): Do not expand the
7132 macro defined by AS_VAR_PUSHDEF before passing it as a

7144 2006-10-14 Paul Eggert <eggert@cs.ucla.edu>
7146 (Imported from Automake.)
7147 * build-aux/install-sh (posix_mkdir): Reject FreeBSD 6.1 mkdir -p -m,
7148 which incorrectly sets the mode of an existing destination
7149 directory. In some cases the unpatched install-sh could do the
7150 equivalent of "chmod 777 /" or "chmod 0 /" on a buggy FreeBSD
7151 system. We hope this is rare in practice, but it's clearly worth
7152 fixing. Problem reported by Alex Unleashed in
7153 <http://lists.gnu.org/archive/html/bug-autoconf/2006-10/msg00012.html>.
7154 Also, don't bother to check for -m bugs unless we're using -m;
7155 suggested by Stepan Kasal.

7159 Import this change from Automake:
7161 2006-08-23 Alexandre Duret-Lutz <adl@gnu.org>
7162 * lib/Autom4te/ChannelDefs.pm (usage): Mention that -Wportability
7163 is enabled by default with gnu and gnits strictness.
7164 Report from Bruno Haible.
7166 2006-03-10 Alexandre Duret-Lutz <adl@gnu.org>

7168 gnu and gnits modes.
7170 Import this change from Config:

7175 Import this change from Gnulib:
7177 2006-09-16 Karl Berry <karl@gnu.org>
7178 * doc/fdl.texi (ADDENDUM): switch to @heading from @appendixsubsec,
7179 to avoid sectioning errors.
7181 Import these changes from Texinfo:
7183 2006-10-04 Karl Berry <karl@gnu.org>
7184 * build-aux/texinfo.tex (\singlequotechar): rename to \codequoteright.

7192 * build-aux/texinfo.tex (\textdegree): New command.
7194 2006-08-12 Karl Berry <karl@gnu.org>

7199 * doc/autoconf.texi (Autoheader Macros): Fix syntax error.
7201 2006-10-13 Stepan Kasal <kasal@ucw.cz>
7203 * doc/autoconf.texi (Autoheader Macros): Warn that the text
7204 added to the template can get mangled.
7206 2006-10-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7208 * lib/autoconf/functions.m4 (AC_FUNC_OBSTACK): In the test,
7209 include the default headers, and redefine obstack_chunk_alloc
7210 and obstack_chunk_free. Fixes false failure with glibc.
7212 2006-10-12 Paul Eggert <eggert@cs.ucla.edu>
7214 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Set as_executable_p,

7227 the NonStop platform.
7228 * doc/autoconf.texi (Posix Variants): Likewise.
7229 * lib/autoconf/specific.m4 (AC_USE_SYSTEM_EXTENSIONS): Likewise.
7231 * lib/m4sugar/m4sh.m4 (AS_TEST_X): New macro.
7232 (AS_EXECUTABLE_P): Use as_test_x rather than as_executable_p.
7233 (_AS_TEST_PREPARE): Set as_test_x rather than as_executable_p.
7234 Use a better substitute, by inspecting the output of "ls"
7235 rather than just using ":".
7236 * lib/autoconf/general.m4 (_AC_LINK_IFELSE): Use AS_TEST_X
7237 rather than AS_EXECUTABLE_P, since we needn't worry about
7238 non-regular files here.
7240 * NEWS: Autoconf-generated shell scripts no longer export BIN_SH,
7241 due to configuration hassles with this. See Tonya Underwood's report
7242 <http://lists.gnu.org/archive/html/bug-autoconf/2006-10/msg00003.html>.

7251 2006-10-11 Stepan Kasal <kasal@ucw.cz>
7253 * lib/m4sugar/m4sh.m4 (AS_BOURNE_COMPATIBLE): Move the
7254 initialization which is not inherited through the environment
7255 (_AS_BOURNE_COMPATIBLE): ... to this new macro.
7256 (_AS_RUN): Call _AS_BOURNE_COMPATIBLE, not AS_BOURNE_COMPATIBLE.

7261 problems with mkdir -p -m.
7263 2006-10-06 Paul Eggert <eggert@cs.ucla.edu>
7265 * lib/autoconf/c.m4 (_AC_PROG_PREPROC_WORKS_IFELSE): Remove
7266 comment about ac_cpp_err; it was incorrect, and anyway
7267 ac_cpp_err is being removed below.
7268 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE): Don't
7269 set ac_cpp_err to 'yesyes' if preproc_warn_flag and werror_flag
7270 are both 'yes'. In fact, don't bother setting ac_cpp_err at all;
7272 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't log our funky tests
7273 with werror_flag and conftest.err and so forth. This is more
7274 compatible with how _AC_PROG_PREPROC_WORKS_IFELSE behaves,
7275 and anyway the user shouldn't normally want to see this gorp logged.
7276 Problem reported by Ralf Wildenhues.
7277 * lib/autoconf/lang.m4 (AC_LANG_WERROR): werror_flag's default is
7278 empty, not 'no', since the rest of the code uses 'test -z'.
7280 2006-10-04 Paul Eggert <eggert@cs.ucla.edu>
7282 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE):
7283 Use a single call to AC_DO_TOKENS rather than multiple, for
7285 (_AC_LINK_IFELSE): Test that resulting file is executable.
7286 Problem reported by mwoehlke in
7287 <http://lists.gnu.org/archive/html/bug-coreutils/2006-10/msg00048.html>.
7289 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Use "test -x /" rather
7290 than creating a file to use with test -x; this is much faster.
7292 2006-10-02 Bruno Haible <bruno@clisp.org>
7294 * lib/autom4te.in (Automake-preselections): Add
7295 AM_GNU_GETTEXT_INTL_SUBDIR, for automake 1.10.
7297 2006-09-27 Stepan Kasal <kasal@ucw.cz>
7299 * doc/autoconf.texi (Writing testsuite.at): Fix a typo: for
7300 standard error, `experr' should be used, not `expout'.
7302 2006-09-26 Paul Eggert <eggert@cs.ucla.edu>
7304 * lib/autoconf/functions.m4 (AC_FUNC_FSEEKO): Don't compile the
7305 fseeko testing program twice; just use the earlier result.
7306 * lib/autoconf/specific.m4 (_AC_SYS_LARGEFILE_MACRO_VALUE):
7307 Set cache var to 'unknown' (not 'no') if leaving the macro unset
7308 still doesn't let the program compile.
7309 (AC_SYS_LARGEFILE): Test for _LARGE_FILES only if earlier tests
7312 * lib/autoconf/functions.m4: Fix problems reported by Ralf Wildenhues.
7313 (AC_FUNC_ERROR_AT_LINE): Don't bother to check for error.h. Just
7314 include it, without including anything else.
7315 (AC_FUNC_FSEEKO): Avoid gcc -Wall warnings about constant
7317 (AC_FUNC_STRNLEN): Require AC_USE_SYSTEM_EXTENSIONS.
7319 2006-09-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7321 * lib/autoconf/functions.m4 (AC_FUNC_ERROR_AT_LINE): Check for
7322 `error.h', and include it, for a `error_at_line' prototype.
7323 Use a nonempty format string in the link test.
7324 * lib/autoconf/functions.m4 (AC_FUNC_WAIT3): Include <sys/wait.h>,
7325 for a declaration of wait3.

7331 can apply to constants too, and that it checks for macro defns.
7332 * lib/autoconf/general.m4 (AC_CHECK_DECL): Assume C89 or better,
7333 and simply cast the identifier to void. This handles structure
7334 values. Problem reported by Ralf Wildenhues.
7335 * tests/semantics.at (AC_CHECK_DECLS): Also check enums.

7809 Require that long long int be at least 64 bits wide. C99 requires
7810 this and enough programs depend on it so we should check for it.
7811 Bruno Haible reports in
7812 <http://lists.gnu.org/archive/html/bug-gnulib/2006-06/msg00286.html>
7813 that long long int is 32 bits wide with some nonstandard compilers.
7814 (AC_TYPE_UNSIGNED_LONG_LONG_INT): Likewise.
7816 2006-06-30 Paul Eggert <eggert@cs.ucla.edu>
7818 * tests/torture.at (Configuring subdirectories): Set CONFIG_SITE
7819 to a nonexistent file, so that we don't have to worry about
7820 a local site configuration that doesn't use /usr/local.
7821 Problem reported by Keith Marshall in
7822 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00133.html>.
7824 2006-06-28 Paul Eggert <eggert@cs.ucla.edu>
7826 * doc/autoconf.texi: Be more consistent about using @acronym with
7827 "HP" and "HP-UX". Remove mention of OSF; the old version wasn't
7828 quite right (it talked about "OSF/Tru64", even though the
7829 operating systems were called OSF/1, Digital UNIX, and Tru64 UNIX,
7830 and it even mentioned "OSF 4"!) and at this point there's little
7831 reason to talk about OSF any more, since it died in 1994.
7832 (Specific Compiler Characteristics): Simplify example of
7833 negative-size array.
7834 (File Descriptors): Reorder to make the text flow better.
7835 Remove joke about "appreciate the various levels"; I didn't get it.
7836 Add remark about HP-UX sh -x bug with stderr noted by Bob Proulx in
7837 <http://lists.gnu.org/archive/html/bug-coreutils/2006-06/msg00225.html>.
7838 (File Descriptors, Limitations of Usual Tools):
7839 Tone down the advice against renaming or removing open files.
7840 (Limitations of Usual Tools): Add a new section, on 'rm'.
7842 2006-06-26 Stepan Kasal <kasal@ucw.cz>
7844 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Use -lX11, not
7845 -lXt in LIBS, idea from Karsten Hopp; this was due since
7848 2005-09-18 Paul Eggert <eggert@cs.ucla.edu>
7849 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Look for X11/Xlib.h
7850 and XrmInitialize rather than X11/Intrinsic.h and XtMalloc
7851 (which belong to Xt, not X itself). See Debian bug 327655.
7853 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7855 * configure.ac (AC_INIT): Bump to 2.60a.
7858 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7862 * configure.ac, NEWS: Update.
7864 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7866 * config/texinfo.tex: Sync from upstream.
7868 * bin/autom4te.in (handle_traces): Transform the `@S|@'
7869 quadrigraph correctly in traces.
7871 * NEWS, lib/Autom4te/C4che.pm, lib/autoconf/functions.m4:
7874 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Expand tests for
7875 datarootdir-related errors only if AC_DATAROOTDIR_CHECKED is
7877 * doc/autoconf.texi (Changed Directory Variables): New node,
7878 to document the whole `datarootdir' business a bit better.
7880 * tests/torture.at (datarootdir workaround): Extend test.
7881 Prompted by report by Alexandre Julliard.
7883 2006-06-22 Paul Eggert <eggert@cs.ucla.edu>
7885 * lib/autoconf/c.m4 (_AC_PROG_CC_C89): Check for C89 incompatibility
7886 when using default mode of IBM C 6 for AIX. Problem and two-line
7887 fix reported by Larry Jones.
7889 2006-06-22 Alexandre Julliard <julliard@winehq.org>
7891 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Avoid warning
7892 about literal '${datarootdir}' if a definition is found in the
7895 2006-06-20 Paul Eggert <eggert@cs.ucla.edu>
7897 * NEWS: Use "M4" rather than "m4" when appropriate.
7898 Problem reported by Eric Blake.
7899 * doc/autoconf.texi: Likewise.
7900 Use @acronym around BSD, GCC, and GNU when appropriate.
7901 (Why GNU M4): Renamed from "Why GNU m4".
7902 (Redefined M4 Macros): Mention that Posix
7903 m4wrap takes only 1 argument, but GNU M4 1.4.x takes more.
7904 (Buffer Overruns): Mention size_t and ptrdiff_t as alternatives
7907 2006-06-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7909 * bin/autom4te.in (handle_output): Do not forbid the empty
7911 * tests/tools.at (autoconf: the empty token): New test.
7913 2006-06-20 Stepan Kasal <kasal@ucw.cz>
7915 * lib/m4sugar/m4sugar.m4 (m4_init): Merge the two m4_wrap
7916 calls, so that we do not care whether they are LIFO or FIFO;
7917 in the m4_wrap, do not check which diversion is the topmost
7918 one, just check that the stack is balanced at the end.
7919 * lib/m4sugar/m4sh.m4 (AS_INIT): We are going to change the
7920 base diversion forever--pop the previous diversion before
7921 opening the new one; consequently, remove the m4_wrap call.
7922 * lib/autotest/general.m4 (AT_INIT): Likewise.
7923 * tests/m4sugar.at: Do not use
7924 m4_wrap([m4_diversion_pop([..])]), for educational purposes.
7926 2006-06-19 Paul Eggert <eggert@cs.ucla.edu>
7927 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7929 * NEWS: Document that m4wrap/m4_wrap might not be LIFO.
7930 * doc/autoconf.texi (Redefined M4 Macros): Likewise.
7931 Rework example of m4wrap token-pasting trouble so that it doesn't
7932 care whether it's LIFO or FIFO.
7933 Fix some "contrary to"s that are awkward in English.
7935 2006-06-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7937 * lib/autoconf/types.m4 (_AC_TYPE_INT): Set `$ac_cv_c_int$1_t'
7938 to `yes' instead of `int$1_t' if the type is found, for more
7939 consistent configure output (where $1 is the number of bits).
7940 (_AC_TYPE_UINT): Likewise for `uint$1_t'.
7941 Suggested by Bruno Haible.
7943 * lib/autoconf/types.m4 (_AC_TYPE_UNSIGNED_INT): Solaris 2.5.1
7944 needs _UINT8_T and _UINT64_T defines as well, to avoid clashes
7945 with system headers. Report by Bruno Haible.
7947 2006-06-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7949 * config/config.guess, config/config.sub: Sync from upstream.
7951 * bin/Makefile.am (autoconf.in): Use `--melt' for autom4te,
7952 in order to avoid picking up an older installed frozen m4sh.m4f.
7953 Besides an outdated shell startup, this could have been created
7954 by an earlier M4 version with incompatible frozen file format.
7956 2006-06-16 Paul Eggert <eggert@cs.ucla.edu>
7958 * README: Recommend m4 1.4.4 instead of 1.4.3..
7959 * doc/autoconf.texi: Likewise.
7960 (Special Chars in Names): Say that $(.FOO) is portable, as
7961 suggested by Stepan Kasal.
7962 (Installation Directory Variables, Build Directories):
7963 (Automatic Remaking, Subdirectories, Fortran Compiler):
7964 (Making testsuite Scripts, Defining Directories):
7965 Quote variable usages better.
7966 (Making testsuite Scripts): Add clean-local rule to makefile
7967 snippet, by Eric Blake.
7968 (Installation Directory Variables): Fix table item font.
7969 Reword slightly to clarify. Generalize advice about
7970 not using special characters to include all file-related
7971 vars, not just VPATH.
7972 (Special Chars in Variables): Warn about special characters in
7974 (Assignments): Clarify default-value example as suggested by
7976 <http://lists.gnu.org/archive/html/autoconf-patches/2006-06/msg00072.html>.
7977 (Special Shell Variables): Note leading ./ or ../, as suggested
7979 (Limitations of Builtins): Under cd, warn about CDPATH.
7980 (The Make Macro MAKEFLAGS): Untabify. Problem reported by
7983 2006-06-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7985 * doc/autoconf.texi (Configuration Actions): Remove duplicate
7986 `@var', for texi2html.
7987 (Systemology): Some more word wrapping, for DVI output.
7988 (autom4te Invocation): The short option for `--melt' is `-M',
7991 2006-06-15 Paul Eggert <eggert@cs.ucla.edu>
7993 * doc/autoconf.texi: More formatting and English tweaks,
7994 many suggested by Ralf Wildenhues.
7995 Reword to avoid "@code{...}'s" and the like, since it's ugly
7996 with Emacs info mode. discontents -> woes.
7997 Put a few "will"s back. time stamp -> timestamp.
7998 side-effect -> side effect.
8000 2006-06-14 Paul Eggert <eggert@cs.ucla.edu>
8002 * doc/autoconf.texi (Initializing configure, Shell Substitutions):
8003 Warn about $@ not persisting. Problem reported by Julien Danjou in
8004 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=372179>.
8005 (Special Chars in Names): Renamed from Leading _ in Macro Names.
8006 Mention other special chars, too.
8008 2006-06-14 Eric Blake <ebb9@byu.net>
8010 * doc/autoconf.texi (The Make Macro MAKEFLAGS): New node.
8012 2006-06-13 Paul Eggert <eggert@cs.ucla.edu>
8014 * doc/autoconf.texi: Some systematic minor improvements, as
8015 follows. Use "makefile" when talking about makefiles
8016 generally (which might be named "makefile" or "Makefile" or even
8017 "foo.mk"), "Makefile" when talking about a specific makefile
8018 called "Makefile". This unclutters the text from weird quotes
8019 (e.g., "`Makefile's" in info mode). Similarly, use "@var{foo}
8020 values" rather than "@var{foo}s" and similar constructs containing
8021 "}s". Use "Make rules" rather than "Makefile rules". Minor
8022 English-language improvements. Change the prefix "sub-" to "sub"
8024 Put blank lines around examples more consistently.
8025 Avoid "rather" and "very" as intensifiers.
8026 Avoid "will" as an auxiliary.
8027 (Limitations of Make): Split this node into....
8028 (Portable Make, $< in Ordinary Make Rules, Failure in Make Rules):
8029 (Leading _ in Macro Names, Backslash-Newline-Newline):
8030 (Backslash-Newline Comments, Long Lines in Makefiles):
8031 (Macros and Submakes, The Make Macro SHELL, Comments in Make Rules):
8032 (obj/ and Make, make -k Status, VPATH and Make):
8033 (VPATH and Double-colon, $< in Explicit Rules):
8034 (Automatic Rule Rewriting, OSF/Tru64 Directory Magic):
8035 (Make Target Lookup, Single Suffix Rules, Timestamps and Make):
8036 New nodes, resulting from splitup of Limitations of Make.
8037 All cross-references changed. Raise the top node from
8038 a section to a chapter, and all subnodes accordingly.
8039 Redo the introductory wording to match the new organization.
8040 (Installation Directory Variables): Use an example that is
8041 closer to what Autoconf actually does. Mention that VPATH's
8042 value should not contain metacharacters or white space.
8043 (Fortran Compiler): Fix a VPATH bug in an example.
8044 (Leading _ in Macro Names): Mention that this problem is no longer
8045 of practical concern.
8046 (VPATH and Make): Reword the advice to make it clearer
8047 that Autoconf and Automake support VPATH in non-GNU make, but
8048 many packages have bugs in this area.
8049 ($< in Explicit Rules): Refer to Build Directories rather
8050 than using a (non-VPATH-safe) example.
8051 (Automatic Rule Rewriting): Mention the sort of disaster that
8052 can ensue with Solaris-style rule rewriting with VPATH.
8054 2006-06-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8056 * doc/install.texi (Compilers and Options): Weaken the
8057 suggestion to use GNU make for VPATH builds.
8059 * lib/autom4te.in (Automake-preselections): Add AM_PROG_CXX_C_O,
8060 AM_PROG_F77_C_O, AM_PROG_FC_C_O, AC_FC_SRCEXT, AC_FC_FREEFORM.
8062 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Fix M4 quotation
8063 in regular expression.
8065 2006-06-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8067 * doc/autoconf.texi (Installation Directory Variables):
8068 Drop extra @samp from `@table @samp' item.
8069 (Limitations of Usual Tools): Comment fix.
8070 Do not nest @samp just to point to other table items.
8071 (Writing testsuite.at) <AT_CHECK>: The second argument to
8072 `@dvar' is already @samp'ed.
8073 (Making testsuite Scripts) <AC_CONFIG_TESTDIR>: Likewise,
8074 do not use @var in the second argument.
8076 2006-06-07 Paul Eggert <eggert@cs.ucla.edu>
8078 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Look for
8079 $as_shell.exe too. Problem reported by Andreas Buening in
8080 <http://lists.gnu.org/archive/html/autoconf/2006-06/msg00038.html>.
8082 2006-06-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8084 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA): Work around
8085 `unused variable' compiler warning, for `-Wall -Werror'.
8086 Reported by Jaap Haitsma in
8087 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00012.html>.
8089 2006-06-06 Paul Eggert <eggert@cs.ucla.edu>
8091 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Remove core file, in
8092 case the compiler dumps core. Problem reported for
8093 OpenServer 5.0.7 by Tim Rice in
8094 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00019.html>.

8098 2006-06-06 Tim Rice <tim@multitalents.net>.

8101 "ERROR" only shows up in "make check" output if there is an

8110 * NEWS: Don't blame non-GNU VPATH compatibility issues on Automake.
8112 * doc/autoconf.texi (Integer Overflow): Mention that INT_MIN % -1
8113 typically overflows on x86 CPUs, even though the C standard
8116 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8118 * configure.ac (AC_INIT): Bump to 2.59e.

8125 * config/texinfo.tex: Sync from upstream.
8127 * bin/autoreconf.in: Trace `LT_CONFIG_LTDL_DIR'; if it has been
8128 seen, invoke libtoolize with `--ltdl' argument.
8129 * lib/autom4te.in (Autoreconf-preselections): Adjust.
8131 Suggested by Eric Blake.
8133 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
8135 * NEWS: Whoops! AC_FUNC_STRNLEN isn't obsolescent. Problem

8150 message issued by AC_REQUIRE.
8151 * tests/m4sugar.at: Check m4_require's error message.
8152 * tests/base.at: Check AC_REQUIRE's error message.
8153 * tests/local.at (AT_CHECK_M4): New macro, almost identical
8155 (AT_CHECK_AUTOM4TE): ... which is now a thin wrapper around
8157 (AT_CHECK_AUTOCONF): Use AT_CHECK_M4; no longer support
8158 `expout' as the last parameter.
8159 * tests/tools.at: Adapt to the above change.
8161 2006-06-04 Stepan Kasal <kasal@ucw.cz>
8163 * doc/autoconf.texi (Limitations of Usual Tools): Correct
8164 information about race-free implementations of mkdir.

8173 2006-06-04 Paul Eggert <eggert@cs.ucla.edu>
8175 * NEWS: GNU make now recommended for VPATH builds.
8176 Mention that some macros are now documented to be obsolescent.
8177 * doc/autoconf.texi:
8178 Prefer "current" to "modern" to describe
8179 currently-used (albeit perhaps old-fashioned) hosts.
8180 Mention which ancient features no longer need to be worried about.
8181 setgid -> set-group-ID
8182 setuid -> set-user-ID (these are the Posix terms)
8183 Fix some misuses of "only".
8184 (AC_C_BACKSLASH_A, AC_C_CONST, AC_C_PROTOTYPES):
8185 (AC_C_STRINGIZE, AC_C_VOLATILE, AC_FUNC_CLOSEDIR_VOID):

8198 Omit longwinded and obsolescent discussion of cp -f.
8199 Modernize discussion of expr, ls.
8200 (Limitations of Make): Modernize discussion of VPATH builds.
8201 Mention $? as a workaround in some cases.
8202 * doc/install.texi (Basic Installation):
8203 Mention "./configure; make; make install" first. Be more
8204 specific about why this file is generic. Remove unnecessary
8205 parens. Remove misleading "only". Remove obsolete advice
8206 about csh. Don't say "configure" takes awhile; say it
8207 might take a while. Suggest CFLAGS=-g rather than CFLAGS=-O2,
8208 and CC=c99 rather than CC=c89, as these are blessed by current
8209 Posix. Recommend GNU make if doing a VPATH build.
8211 2006-06-03 Paul Eggert <eggert@cs.ucla.edu>
8213 * doc/autoconf.texi: Use a consistent style "$ @kbd{...}" for
8214 examples involving shell prompts.

8232 2006-05-31 Paul Eggert <eggert@cs.ucla.edu>
8234 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be even more conservative
8235 about quoting the case statement, just in case.

8253 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
8255 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be more conservative
8256 about quoting ac_try: quote all of it, if any of it seems suspicious.
8257 This means we don't have to worry about ${ or sed any more.
8258 Also, double-quote the case statement, to work around misuses via
8259 underquoting as reported by Ralf Wildenhues in
8260 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00169.html>.

8276 Problem reported by Ralf Wildenhues in
8277 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00160.html>.
8278 (AC_TRY_EVAL, AC_TRY_COMMAND, _AC_EVAL): Go back to the
8279 pre-2006-05-26 definitions, but leave in the comments that
8280 these macros are dangerous and should not be used.
8281 (_AC_DO_ECHO): Renamed from _AC_EVAL_ECHO. All callers changed.
8282 (_AC_DO): Renamed from _AC_EVAL. All callers changed.
8283 (_AC_DO_STDERR): Renamed from _AC_EVAL_STDERR. All callers changed.
8284 (_AC_DO_VAR): Renamed from AC_TRY_EVAL.
8285 (_AC_DO_TOKENS): Renamed from AC_TRY_COMMAND.
8287 2006-05-29 Paul Eggert <eggert@cs.ucla.edu>
8289 * lib/autoconf/status.m4 (AC_OUTPUT_MAKE_DEFS): Rewrite to avoid
8290 the use of 'tr', since this is our only use of 'tr'.
8292 2006-05-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8293 and Paul Eggert <eggert@cs.ucla.edu>
8295 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE):
8296 Don't assume 'grep' works on long lines, since AIX grep doesn't.
8298 2005-05-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8300 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Do not use `grep' on
8301 the output file in the `${datarootdir}' test.
8303 2005-05-28 Stepan Kasal <kasal@ucw.cz>
8304 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8306 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If we have not seen
8307 mention of `datarootdir' in the input file(s), but literal
8308 `${datarootdir}' in the output file, and we haven't warned yet,
8309 then warn as well: the user may have (erroneously) used
8310 `AC_SUBST([mydatadir], [$datadir/my])' instead of the correct
8311 `AC_SUBST([mydatadir], ['${datadir}/my'])'.
8312 * tests/torture.at (datarootdir workaround): Extend this test.
8315 2006-05-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8316 and Paul Eggert <eggert@cs.ucla.edu>
8318 * doc/autoconf.texi (autoheader Invocation): The first argument to
8319 `AC_DEFINE_UNQUOTED' need not be a literal. Mention the
8320 alternatives and clear up the language a bit.
8322 2006-05-27 Paul Eggert <eggert@cs.ucla.edu>
8324 * NEWS: Reword notice for AC_TRY_COMMAND, AC_TRY_EVAL,
8325 ac_config_guess, ac_config_sub, ac_configure.
8326 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
8327 Fix typo that prevented an unnecessary space from being removed.
8328 Problems reported by Ralf Wildenhues in:
8329 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00143.html
8331 2006-05-26 Paul Eggert <eggert@cs.ucla.edu>
8333 * doc/autoconf.texi (Particular Programs, Limitations of Usual Tools):
8334 Use better wording to talk about AC_PROG_MKDIR_P's thread-safety.
8335 Don't use the term "thread-safe" to talk about mkdir race
8336 conditions, since the problem is more a process than a thread
8337 issue. Problem reported by Stepan Kasal in:
8338 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00088.html
8339 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Use code that mimics
8340 the test for 'install' more closely. Look at MKDIR_P first.
8341 Look in the PATH, and at /opt/sfw/bin.
8342 Look for a 'gmkdir' program as well (Solaris 10 /opt/sfw/bin/gmkdir).
8343 Don't bother to try mkdir -p, since we already check mkdir --version;
8344 just look at the version number. (There's no easy way to check
8345 for race-free implementations.)
8346 * tests/tools.at (autoconf: subdirectories): Adjust to above
8347 changes, since MKDIR_P now might end in "/mkdir -p".
8349 * doc/autoconf.texi (autoheader Invocation): Mention that the
8350 first arg of AC_DEFINE_UNQUOTED must be a literal.
8351 Problem reported by Ben Pfaff in
8352 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00090.html>.
8354 * NEWS: Mention that AC_TRY_COMMAND and AC_TRY_EVAL may be removed.
8355 * doc/autoconf.texi (Special Chars in Variables): New section.
8356 (Preset Output Variables): Warn about special chars in CPPFLAGS.
8357 (Installation Directory Variables): Quote $(datadir) better.
8358 (Limitations of Builtins): Describe some of eval's trickiness.
8360 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Simplify quoting.
8361 * lib/autoconf/fortram.m4 (_AC_PROG_FC_V_OUTPUT): Likewise.
8362 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Put leading space
8363 in front of every arg, not just trailing args. Quote apostrophes.
8364 (_AC_EVAL_ECHO): New macro.
8365 (_AC_EVAL, AC_EVAL_STDERR): Use it. Quote arg of eval.
8366 (AC_TRY_EVAL, AC_TRY_COMMAND): Mention that these macros might get
8368 (_AC_LINK_IFELSE): Use proper rule for shell continuation lines,
8369 exposed by quoting of eval argument. Put the command on line line
8371 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): Use eval more safely.
8372 (_AC_PATH_X, AC_PATH_X): Quote more safely.
8373 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Use eval more safely.
8374 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Don't use eval.
8375 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Minor style change.
8376 Handle special chars in prefix, ac_srcdir, ac_aux_dir.
8377 Use eval more safely.
8378 (_AC_OUTPUT_CONFIG_STATUS): Adjust to above changes.
8379 * lib/m4sugar/m4sh.m4 (AS_VAR_GET): Note that this API needs
8381 * tests/base.at (AC_TRY_COMMAND): Use proper rule for shell continuation
8382 lines, exposed by quoting of eval argument.
8384 2006-05-26 Stepan Kasal <kasal@ucw.cz>
8385 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8387 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Drop the
8388 initialization of `ac_cv_exeext', do not override it if it was
8389 already set, unless it was set to `no', for compatibility with
8390 Autoconf-2.13, and comment this.
8391 Do not export `ac_cv_exeext', Libtool hasn't needed this for years.
8392 (_AC_COMPILER_EXEEXT_DEFAULT): Likewise, do not export it.
8393 (_AC_COMPILER_EXEEXT_WORKS, _AC_COMPILER_EXEEXT_CROSS): Typos.
8394 * doc/autoconf.texi (Compilers and Preprocessors) <EXEEXT>:
8395 Document that this test may be overridden by setting
8398 2006-05-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8400 Revert these two patches:
8402 2006-04-06 Eric Blake <ebb9@byu.net>
8403 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_O): Inside cache
8404 check, s/ac_exeext/ac_cv_exeext/. Fixes regression introduced
8407 2006-04-01 Stepan Kasal <kasal@ucw.cz>
8408 Clean up _AC_COMPILER_EXEEXT* macros.
8409 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't try to
8410 detect exeext, it will be done by _AC_COMPILER_EXEEXT_O; just set
8411 ac_file to the name of the default output file and call
8412 _AC_COMPILER_EXEEXT_WORKS. Move the definition of ac_files and the
8413 initial `rm' of the candidate files...
8414 (_AC_COMPILER_EXEEXT): ... here and simplify them. Moreover, use
8415 the same list in subsequent `rm' calls, and for the temporary
8416 redefinition of ac_clean_files; call _AC_COMPILER_OBJEXT at the end,
8417 and don't call the other _AC_COMPILER_EXEEXT_* macros directly, use...
8418 (_AC_COMPILER_EXEEXT_TESTS): ... this new macro.
8419 (_AC_COMPILER_EXEEXT_O): Don't export ac_cv_exeext, it's not needed (or
8420 no longer needed) by libtool. Make it a cache check.
8421 (_AC_COMPILER_EXEEXT_CROSS): Remove the comment, it was obviously
8422 copied here by mistake.
8423 (AC_NO_EXECUTABLES): Redefine _AC_COMPILER_EXEEXT_TESTS, not
8424 _AC_COMPILER_EXEEXT.
8425 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX, AC_PROG_OBJC): Do not call
8426 _AC_COMPILER_OBJEXT directly.
8427 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
8429 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8431 * doc/autoconf.texi (Limitations of Usual Tools) < sed (`t')>:
8432 Fix description of how the buggy `sed' works.
8434 2006-05-25 Noah Misch <noah@cs.caltech.edu>
8438 * lib/Autom4te/XFile.pm (lock): Allow EOPNOTSUPP, besides
8439 ENOLCK. Only mention `make -j' when applicable. Only raise
8440 fatal errors when `make -j' is involved. Improve error message.
8442 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8444 * doc/autoconf.texi (Here-Documents): We now know more about
8445 the variable expansion in here documents bug.
8446 Thanks to Tim Rice and Stepan Kasal.
8448 * doc/autoconf.texi (Making testsuite Scripts): Add an example
8449 how to use TESTSUITEFLAGS. Suggested by Eric Blake.
8451 2006-05-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8453 * tests/autotest.at (Multiline command from M4 expansion):
8454 No failure to be expected if the shell quotes newlines in
8455 commands in the `set -x' output. Report by Tim Rice.
8458 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
8460 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Don't use shell
8461 expansion in the here-documents used by config.status, as that
8462 runs afoul of the Korn shell version M-12/28/93d bug described in
8463 the Autoconf manual, and this in turn causes a Coreutils 5.95 build to
8464 fail as described by Tim Rice and diagnosed by Ralf Wildenhues in
8465 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00082.html>.
8467 2006-05-23 Jim Meyering <jim@meyering.net>
8469 * lib/autoconf/functions.m4 (AC_FUNC_LSTAT_FOLLOWS_SLASHED_SYMLINK):
8470 Fix typo introduced with 2006-04-02 change. It reversed the sense
8473 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
8475 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Simplify ac_dA and
8476 ac_dB slightly, to save bytes in the script.
8477 Max out at 50 lines, rather than 96; this is more likely
8478 (though not guaranteed) to avoid obscure 'sed' failures.
8480 2006-05-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8482 * lib/autotest/general.m4 (AT_INIT): UnixWare `tr' may interpret
8483 `tr -d -' as bad option argument. Work around this by deleting
8484 an unrelated character.
8485 Report by Tim Rice <tim@multitalents.net>.
8487 2006-05-22 Paul Eggert <eggert@cs.ucla.edu>,
8488 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
8489 Stepan Kasal <kasal@ucw.cz>
8491 * doc/autoconf.texi (Particular Programs): Do not promise that
8492 we always prefer the GNU version of the program, and that we
8493 search according to PATH; both rules can have exceptions.
8494 Update description of AC_PROG_GREP, AC_PROG_EGREP, AC_PROG_FGREP,
8495 AC_PROG_SED. Move descriptions of limitations
8496 to the Limitations of Usual Tools section.
8497 (Limitations of Usual Tools) <sed>: Mention script length
8498 limitations with Solaris /usr/ucb/sed.
8499 <grep>: Fix wording for empty alternative. Mention that -c and
8500 -l should not be combined, and that -E and -F should not be
8503 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
8504 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8506 * lib/autoconf/programs.m4 (AC_PROG_SED): Catch script length
8507 limits in Solaris 8 /usr/ucb/sed by testing a long script.
8509 2006-05-22 Stepan Kasal <kasal@ucw.cz>
8511 * doc/autoconf.texi (Defining Symbols): Literal parameter of
8512 AC_DEFINE is now passed to m4_pattern_allow.
8513 * NEWS: Mention that; likewise for AC_SUBST.
8514 * lib/autoconf/general.m4 (AC_DEFINE_TRACE_LITERAL): Pass
8515 the parameter to m4_pattern_allow.
8516 * tests/tools.at: Add a check for that.
8518 2006-05-22 Stepan Kasal <kasal@ucw.cz>
8520 * lib/autoconf/status.m4: Fix typos.
8522 2006-05-21 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8524 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Remove
8525 only the files that this macro generates.
8527 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
8529 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: For
8530 the HP-UX sed limitation of 99 commands, labels do not count.
8531 * lib/autoconf/status.m4 (_AC_SED_CMD_LIMIT): Mention that
8533 (_AC_OUTPUT_HEADER): Revert the change from 2006-05-19.
8535 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
8537 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT):
8538 Import the following fix from coreutils:
8540 2006-01-13 Jim Meyering <jim@meyering.net>
8542 Invoke AC_CHECK_FUNCS(getmntent) unconditionally so that tests of
8543 $ac_cv_func_getmntent (e.g., in gl_LIST_MOUNTED_FILE_SYSTEMS) need
8544 not double-quote uses of that variable, to accommodate the rare
8545 case in which getmntent is available in none of the libraries
8546 checked. This happens at least on FreeBSD 5.0.
8548 2006-05-20 Paul Eggert <eggert@cs.ucla.edu>
8550 * lib/autoconf/general.m4 (AC_CONFIG_AUX_DIRS): Bring back
8551 ac_config_guess, ac_config_sub, and ac_configure, since evidently
8552 some other programs unwisely rely on these undocumented vars.
8553 But put in warning comments about them.
8554 Problem reported by Ralf Wildenhues in
8555 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00068.html>.
8556 * NEWS: Document that these variables are intended to go away.
8558 2006-05-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8560 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): Require AC_PROG_CXX,
8561 and set the language to C++ (analogous to the equivalent Fortran
8564 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): New macro.
8565 * doc/autoconf.texi (C++ Compiler): Document it.
8566 * lib/autoconf/fortran.m4 (_AC_PROG_FC_C_O): Adjust comment.
8569 2006-05-19 Paul Eggert <eggert@cs.ucla.edu>
8571 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Fix off-by-one bug
8572 that caused config.status to generate 100-command sed scripts; the
8573 portable limit is 99.
8575 2006-05-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8577 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Name temporary
8578 variable `ac_d' instead of `d' to avoid infringing namespace.
8579 Report by Ralf Menzel.
8581 2006-05-18 Paul Eggert <eggert@cs.ucla.edu>
8583 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Don't prepend
8584 $ac_top_build_prefix to $MKDIR_P if it's just 'mkdir -p'.
8585 * tests/tools.at (autoconf: subdirectories): New test, taken from
8586 the corresponding problem report by Ralf Wildenhues in:
8587 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00053.html
8589 * lib/autoconf/functions.m4 (AC_REPLACE_FNMATCH, AC_FUNC_FNMATCH_GNU):
8590 Quote some uses of shell variables if they might suffer unexpected
8591 globbing. This doesn't fix all instances of quoting problems that
8592 I found, just the easy ones that look safe.
8593 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR, _AC_INIT_HELP):
8594 (AC_CONFIG_AUX_DIR, AC_CONFIG_AUX_DIR_DEFAULT, AC_CONFIG_AUX_DIRS):
8595 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST, AC_CANONICAL_TARGET):
8596 (AC_CACHE_LOAD, AC_CACHE_SAVE): Likewise.
8597 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF, _AC_PATH_X_DIRECT): Likewise.
8598 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Likewise.
8599 * lib/autoconf/status.m4 (_AC_OUTPUT_LINK, _AC_OUTPUT_SUBDIRS):
8601 * lib/autotest/general.m4 (_AC_INIT_PARSE_ARGS): Likewise.
8602 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Likewise.
8604 2006-05-18 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8606 * bin/autoreconf.in ($help): Reword according to the manual.
8607 Suggested by Olly Betts.
8609 2006-05-17 Olly Betts <olly@survex.com> (tiny change)
8610 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8612 * bin/autoreconf.in: Pass the directory argument to
8613 `require_configure_ac'. Fix comment.
8614 * tests/torture.at (Configuring subdirectories): Expose this.
8615 Reported by Olly Betts.
8617 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8619 * lib/Automake/Configure_ac.pm, lib/Automake/Channels.pm,
8620 lib/Automake/FileUtils.pm, lib/Automake/Struct.pm: Sync from
8621 Automake as follows:
8623 * lib/Autom4te/Configure_ac.pm (find_configure_ac): Use
8624 `$configure_in' instead of `configure.in', to preserve
8625 directory component.
8627 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8629 * config/config.guess, config/config.sub, config/texinfo.tex,
8630 doc/make-stds.texi, doc/standards.texi: Sync from upstream.
8632 2006-05-14 Paul Eggert <eggert@cs.ucla.edu>
8634 * lib/autoconf/headers.m4 (AC_HEADER_STDBOOL): Fix overly-picky
8635 test for C99 conformance; (bool) 0.5 is an integer constant
8636 expression, but (bool) -0.5 is not. Problem reported by Fedor
8637 Sergeev in <http://forum.sun.com/jive/thread.jspa?threadID=96202>.
8639 2006-05-13 Paul Eggert <eggert@cs.ucla.edu>
8641 * doc/autoconf.texi (Particular Programs): AC_PROG_MKDIR_P now
8642 sets MKDIR_P, not mkdir_p, to avoid collisions with Automake.
8643 Warn about obsolete install-sh files. Remove stray sentence
8644 fragment and fix cross reference.
8645 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Don't insist on
8646 install -d; this undoes the 2006-05-10 change.
8647 (MKDIR_P): Mark with AN_MAKEVAR.
8648 (AC_PROG_MKDIR_P): Fall back on $ac_install_sh, not $INSTALL, so
8649 that we don't require $INSTALL to be thread-safe. Move comments
8650 out of generated code. Require AC_CONFIG_AUX_DIR_DEFAULT instead
8651 of AC_PROG_INSTALL. Output a message saying that we're checking
8652 mkdir -p. Set MKDIR_P rather than mkdir_p. Do special magic for
8653 MKDIR_P instead of AC_SUBST.
8654 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE, _AC_OUTPUT_CONFIG_STATUS):
8655 Special magic for MKDIR_P, too.
8656 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Remove comment that defeated
8658 * tests/local.at (AT_CHECK_ENV): mkdir_p -> MKDIR_P.
8660 2006-05-11 Paul Eggert <eggert@cs.ucla.edu>
8662 Sync from Automake, as follows:
8664 2006-05-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8665 * config/install-sh: Initialize IFS, so field splitting isn't
8667 * config/mkinstalldirs: Likewise.
8668 * config/missing: Remove superfluous quotes. Replace all uses of
8669 `[' by `test', for consistency, and for..
8670 * config/missing (sed_minuso, sed_output): New variables.
8671 (autom4te, help2man, makeinfo): Use them. Unifies detection of
8672 `-o FILE', `--output FILE', `--output=FILE', stricter regex.
8673 Fixes `missing' to detect `--output' for help2man. Fixes
8674 PR automake/483. Report by Dennis J. Linse.
8675 (autom4te): Document in `missing --help'.
8677 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
8679 * NEWS: New macro AC_PROG_MKDIR_P. AS_MKDIR_P is now more robust.
8680 * config/install-sh: Don't use 'path' to talk about file names,
8681 as per GNU coding standards. Close a race condition reported by Ralf
8682 Wildenhues and Stepan Kasal. There is still a race condition
8683 on hosts that predate Posix 1003.1-1992, but we can't help this.
8684 Don't mishandle weird characters like space on pre-Posix hosts.
8685 Invoke mkdir at most once per dir arg on pre-Posix hosts.
8686 * doc/autoconf.texi (Programming in M4sh): Cross-reference to
8687 AC_PROG_MKDIR_P from AS_MKDIR_P.
8688 (Limitations of Usual Tools): Cross-reference to AC_PROG_MKDIR_P
8689 from mkdir. Mention that Autoconf 2.60 install-sh is safe but
8690 earlier editions are not (including Automake 1.8.3).
8691 Do not suggest mkinstalldirs for thread-safety.
8692 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Insist on an 'install'
8693 that understands -d, so that AC_PROG_MKDIR_P can fall back on $INSTALL.
8694 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Make it more robust in the
8695 presence of special characters and race conditions.
8696 * tests/local.at (AT_CHECK_ENV): Add mkdir_p to the list of variables
8697 in Autoconf's name space.

8700 and Paul Eggert <eggert@cs.ucla.edu>
8702 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): New macro, taken
8703 from Automake with minor changes.

8706 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
8708 * config/install-sh: Update to Automake CVS version, as follows:
8709 2006-04-25 Stepan Kasal <kasal@ucw.cz>
8710 * lib/install-sh: Simplify the expr implementation of dirname.
8711 2006-04-24 Paul Eggert <eggert@cs.ucla.edu>
8712 * lib/install-sh: Handle --, and diagnose unknown options.
8714 2006-05-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8716 * tests/Makefile.am (AUTOTEST): Use `$(MY_AUTOM4TE)' instead of
8717 `./autom4te' to create `./testsuite', since the `all' target
8718 will ensure its presence, but `installcheck' should not create
8719 the uninstalled wrappers.
8721 * tests/torture.at (Unusual Automake input files): Skip if we
8722 detect automake < 1.8.
8724 2006-05-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8726 * lib/autoconf/c.m4 (AC_PROG_CC_STDC): If ac_cv_prog_cc_stdc
8727 is set to `no', then that overrides and sets ac_cv_prog_cc_c89
8728 and ac_cv_prog_cc_c99 to `no', for backward compatibility.
8731 2006-05-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8733 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Take care not to
8734 munge (multiple) white space and other oddities.
8735 * tests/torture.at (AT_CHECK_AC_ARG_VAR): Make sure to M4-escape
8736 single quotes in variable assignment.
8737 (AC_ARG_VAR, configure invocation): Adjust tests to expose this
8738 and similar failures by adding multiple spaces, tabs, and other
8740 Report and different test suggested by Francesco Romani
8741 <fromani@gmail.com> and Andrew Church <achurch@achurch.org>.
8743 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): When we escape
8744 single quotes, we only need to search for single quotes; this
8745 both simplifies the search pattern, and makes us less
8746 susceptible to `echo' variations for arguments not containing
8748 (_AC_ARG_VAR_VALIDATE): Likewise.
8750 2006-05-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8752 * doc/autoconf.texi (Special Shell Variables) <IFS>: Document

8763 * doc/autoconf.texi: Use @option systematically.
8765 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>

8768 * doc/autoconf.texi (Limitations of Usual Tools): Add a paragraph
8770 (Integer Overflow): Mention the special case of integer division
8773 2006-05-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8775 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Cater for
8776 traditional shells like the Solaris one that do not use the
8777 first IFS character for assembling `$*'.
8778 Prompted by a related report from autoconf_bug@nro.ca.
8780 2006-05-01 Paul Eggert <eggert@cs.ucla.edu>
8781 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

8803 (AC_COMPILE_IFELSE, AC_TRY_COMPILE, _AC_LINK_IFELSE)
8804 (AC_LINK_IFELSE, AC_TRY_LINK, AC_COMPILE_CHECK): Likewise.
8806 2006-04-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8808 * doc/autoconf.texi (Limitations of Make): Clean up markup.

8816 * doc/autoconf.texi (Limitations of Builtins): Document FreeBSD
8817 /bin/sh set unsorted output.

8827 with status 1, not merely nonzero. Clarify exit declaration.
8828 (Run Time): Move C exit status stuff to new Exiting Portably section.
8829 (Systemology): Mention Posix and levenez. Update v7 reference.
8830 (Portable Shell): Mention the Posix shell.
8832 2006-04-25 Stepan Kasal <kasal@ucw.cz>
8834 * bin/autoconf.as (me): Replace by as_me.
8836 2006-04-25 Paul Eggert <eggert@cs.ucla.edu>
8838 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Don't use AS_ERROR,
8839 since as_me isn't set yet.
8841 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
8843 Prepare for deprecation of AS_BASENAME and AS_DIRNAME, and fix
8844 a few minor bugs in this area.
8846 * doc/autoconf.texi (Programming in M4sh): Comment out the
8847 documentation of AS_BASENAME, for now.
8848 (Shell Substitutions): Do not use AS_DIRNAME in an example.
8849 (Limitations of Builtins) <basename>: Do not refer to
8851 * bin/autoconf.as (me): Don't use AS_BASENAME.
8852 (dir): Remove the unused variable.
8853 * lib/m4sugar/m4sh.m4 (_AS_DETECT_REQUIRED): Renamed from
8854 AS_DETECT_REQUIRED. All uses changed.

8862 (_AS_DIRNAME_PREPARE): Likewise.
8863 (_AS_DIRNAME_EXPR): Renamed from AS_DIRNAME_EXPR. All uses changed.
8864 (_AS_DIRNAME_SED): Renamed from AS_DIRNAME_SED. All uses changed.
8865 (AS_DIRNAME): Use "dirname --".
8867 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
8869 * doc/autoconf.texi (Runtime): Renamed from "Run Time". All uses
8870 of "run time" and "run-time" changed to "runtime", for consistency.
8871 * lib/autoconf/fortran.m4: Likewise (in comment).
8872 * lib/autoconf/functions.m4: Likewise.
8873 * lib/autoconf/general.m4: Likewise.
8874 * lib/autoconf/headers.m4: Likewise.
8876 * doc/autoconf.texi (Run Time): Document the exit status situation
8877 with more accuracy and detail.
8879 2006-04-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8881 * doc/autoconf.texi (Introduction): The GNU Autoconf Macro
8882 Archive is not officially `GNU' any more. Update URL.
8883 (Defining Directories): Likewise
8884 * lib/autoconf/c.m4 (AC_C_RESTRICT): Update URL.
8886 2006-04-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8888 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Remove the leading
8889 newline from the `trap' code to finish `config.log'; the NetBSD
8890 /bin/sh resets the exit status after an empty command, as
8891 documented in doc/autoconf.texi.
8892 Reported by Dalibor Topic <robilad@kaffe.org>.
8894 2006-04-19 Paul Eggert <eggert@cs.ucla.edu>
8896 * doc/autoconf.texi (C Compiler): Clarify AC_C_TYPEOF.
8897 Suggested by Bruno Haible.
8899 2006-04-18 Paul Eggert <eggert@cs.ucla.edu>
8901 * configure.ac (ac_cv_sh_n_works): Don't try to test for it, since
8902 some shells (e.g., Solaris 8 /bin/sh) implement it verrrry slowly.
8903 Instead, just list the shells that we know work.
8904 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Remove 2nd arg. All uses
8905 changed. Be more cautious about the _cv_ variable.
8906 * tests/tools.at (Syntax of the shell scripts): Check the
8907 _cv_ variable once, at first, to avoid an internal autoconf error
8908 when sh -n does not work.
8910 2006-04-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8912 * lib/Autom4te/FileUtils.pm: Sync from Automake.
8914 2006-04-16 Paul Eggert <eggert@cs.ucla.edu>
8916 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Don't
8917 use ">&-" since we're only 99.999% sure that this is portable,
8918 and since the MinGW bug is fixed in a different way.
8919 * lib/autotest/general.m4 (AT_INIT): Likewise.
8921 2006-04-16 Stepan Kasal <kasal@ucw.cz>
8923 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Handle --recheck
8924 before opening config.log, to avoid hitting a bug on MinGW.
8926 2006-04-14 Paul Eggert <eggert@cs.ucla.edu>
8928 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Close
8929 AS_MESSAGE_LOG_FD before reopening it onto the log file.
8930 This works around a MinGW bug reported by Eric Paire.
8931 Make sure that all writes to the log file append to it,
8932 rather than possibly losing data.
8933 * lib/autotest/general.m4 (AT_INIT): Likewise.
8935 2006-04-14 Stepan Kasal <kasal@ucw.cz>
8937 * lib/Autom4te/FileUtils.pm (find_file): Fix a typo in the
8940 2006-04-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8944 * configure.ac (AC_INIT): Bump to 2.59d.
8946 2006-04-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8950 * Makefile.maint (news-date-check): Do not require a leading `*'
8951 before the release date in NEWS.
8953 2006-04-12 Stepan Kasal <kasal@ucw.cz>
8954 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8956 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If the templates for
8957 the instantiated file do not contain the string 'datarootdir'
8958 but contain @datadir@, @docdir@, @infodir@, @localedir@, or
8959 @mandir@, replace the reference '${datarootdir}' by the value.
8960 * tests/torture.at (datarootdir workaround): New test.
8961 * NEWS: Advertise this temporary fixup.
8962 Based on a patch by Bruno Haible, reported and analyzed by
8963 Paul Eggert and Noah Misch.
8965 2006-04-12 Eric Blake <ebb9@byu.net>
8967 * tests/autotest.at (Debugging a failed test): Fix comment.
8969 2006-04-12 Stepan Kasal <kasal@ucw.cz>
8971 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): Simplify the summary of
8972 all the changes since 2006-04-07.
8974 2006-04-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8976 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): If `ln -s file1 file2'
8977 succeeded, but `ln -s file dir' failed, take care to remove the
8978 leftover target before the next test, to prevent its spurious
8979 failure; also make sure `ln file dir' works before selecting it.
8980 Thanks to Keith Marshall for pointing this out.
8983 * lib/autotest/general.m4 (AT_INIT): Store quoted variable
8984 assignments in `at_debug_args', so that we put them correctly
8985 in the `run' script.
8986 * tests/autotest.at (Debugging a failed test): Unmark XFAIL.
8987 Reported by Eric Blake.
8989 2006-04-11 Eric Blake <ebb9@byu.net>
8991 * tests/autotest.at (AT_CHECK_AT): Add new argument, to allow
8992 top-level tests after micro-suite has been run. Used in...
8993 (Debugging a successful test, Debugging script and environment),
8994 (Debugging a failed test): ...these new tests. The first of these
8996 * lib/autotest/general.m4 (_AT_CREATE_DEBUGGING_SCRIPT): New
8997 macro, split out from...
8998 (AT_INIT): ...here, so that using -d also generates a run script.
8999 Document that -d inhibits top-level logging.
9000 * doc/autoconf.texi (testsuite Invocation): Document that -d only
9001 inhibits top-level logging; debug scripts are created.
9003 * lib/autotest/general.m4 (_AT_CHECK): Avoid syntax error on empty
9005 * tests/autotest.at (Empty test, Empty check): New test to check it.
9007 * lib/autoconf/c.m4 (AC_C_CONST, AC_C_VOLATILE): Avoid warnings
9010 2006-04-10 Stepan Kasal <kasal@ucw.cz>
9012 * tests/mktests.sh: Use "trap '' 0", not "trap 0". Do not touch
9013 the files if a problem appears. Make the empty *.at files
9014 read-only, too. Proposed by Ralf Wildenhues.
9016 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9018 * config/Makefile.am: Add comment to force updated Makefile.in.
9020 * lib/freeze.mk: Fix typo in comment. Unlike the last, white
9021 space only patch to this file, this patch causes the Makefile.in
9022 files that include freeze.mk to be updated, and thus have a
9023 newer time stamp again, which in turn makes a pristine CVS
9024 checkout have correct time stamps.
9026 * Makefile.maint (cvs-sv): New macro, to be used..
9027 (config.guess-url_prefix, config.sub-url_prefix)
9028 (texinfo.tex-url_prefix, standards.texi-url_prefix): ..here;
9029 point to CVS text checkout of Gnulib files.
9030 (copyright-check): Bump current year.
9031 (announcement): Do not hard-wire `./announce-gen'.
9032 (cvs-update): Propagate failures of `cvs' and `move-if-change'
9034 * Makefile.cfg (executable-update): Use `chmod a+x' instead of
9036 (wget_files): Update config.guess, config.sub, texinfo.tex by
9037 `wget-update', now that their URLs work again.
9039 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
9041 * doc/autoconf.texi (Particular Types): Don't use AC_CHECK_TYPE.
9042 Problem noted by Paul D. Smith.
9044 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9046 * doc/autoconf.texi: Remove unused words from word list.
9047 * .x-sc_prohibit_atoi_atof, .x-sc_space_tab, .x-sc_sun_os_names,
9048 .x-sc_trailing_space: New files.
9050 * doc/standards.texi: Sync from gnulib.
9052 * NEWS, doc/autoconf.texi (AC_LIBOBJ vs LIBOBJS): Mark
9053 `LIBOBJDIR' as experimental.
9055 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): MSYS `ln -s' fails
9056 with a target directory; it's internally implemented as `cp'
9057 anyway, but since Autoconf advertises the possibility to use
9058 a target directory when LN_S is `ln -s', we need to find out.
9059 Reported by Rolf Ebert <rolf.ebert.gcc@gmx.de> against MSYS,
9060 analyzed by Keith Marshall <keith.marshall@total.com>.
9064 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
9066 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Just output
9067 confdefs.h as-is. In general, if it has backslash-newline or the
9068 like, then it doesn't work either to sort or to remove empty
9071 2006-04-09 Stepan Kasal <kasal@ucw.cz>
9073 * tests/Makefile.am (AUTOCONF_FILES): Fix typo in the comment.
9075 2006-04-09 Alexandre Duret-Lutz <adl@gnu.org>
9077 * lib/autom4te.in (Automake-preselections): Preselect
9080 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>
9082 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Use '\'' for an
9083 apostrophe within a single-quoted string, as this is the usual
9084 tradition and is easier to read than '"'"'. Don't rely on the
9085 shell treating "$/" like '$/'. Use a more-consistent indenting
9088 2006-04-09 Eric Blake <ebb9@byu.net>
9090 * tests/autotest.at (Backquote command substitution),
9091 (Multiline backquote command substitution): Remove mistaken
9092 AT_NO_CMDSUBST from the 2006-03-14 patch, which was meant to be
9094 (Parenthetical command substitution, Multiline parenthetical
9095 command substitution): here.
9097 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>
9099 Import macros from gnulib (often changing their name).

9130 AC_TYPE_UINTMAX_T, AC_TYPE_UINTPTR_T, AC_TYPE_UNSIGNED_LONG_LONG_INT.
9131 (C Compiler): Move AC_C_LONG_DOUBLE to ...

9174 Revert the patch from 2006-04-01 and only improve
9175 _AS_DETECT_BETTER_SHELL:
9177 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Do not optimize; do not
9178 skip nonexistent directories.
9179 (_AS_DETECT_BETTER_SHELL): The optimization is moved here--try
9180 only shell candidates which exist.
9181 (AS_UNAME): No need to give three parameters to _AS_PATH_WALK.
9182 * lib/autotest/general.m4 (AT_INIT): No need to give three
9183 parameters to _AS_PATH_WALK.
9185 2006-04-07 Stepan Kasal <kasal@ucw.cz>,
9186 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9188 * bin/autoupdate.in (handle_autoconf_patches): Change the way we
9189 distinguish m4sugar macros.
9190 * tests/tools.at (autoupdating with aclocal and m4_include):
9191 New test. Bug reported by Gary V. Vaughan <gary@gnu.org>,
9192 test case by Noah Misch <noah@cs.caltech.edu>.
9194 2006-04-07 Stepan Kasal <kasal@ucw.cz>
9196 Revert my change from 2006-03-17, in other words:
9197 * lib/m4sugar/m4sh.m4 (AS_BOURNE_COMPATIBLE): Insert BIN_SH=xpg4
9199 (AS_SHELL_SANITIZE): Remove DUALCASE=1.
9200 * doc/autoconf.texi (Special Shell Variables) <BIN_SH>: Say that
9203 2006-04-07 Eric Blake <ebb9@byu.net>
9205 * doc/autoconf.texi (Programming in M4sh): Document that
9206 AS_MKDIR_P exits the script on failure.
9207 * lib/autotest/general.m4: Remove redundant AS_ERROR.
9209 2006-04-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9211 * config/elisp-comp, config/install-sh, config/mdate-sh,

9228 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9230 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): Fix the detection of
9231 whether `set' quotes correctly: redirect stderr of the tested
9232 `set', and use a subshell, for Ultrix; use `sed' instead of
9233 `grep' for zsh `set' which may write binary output; match only
9234 at the beginning of a line, to avoid false positives.
9235 In order to avoid false positives by unrelated variables with
9236 multiline content, put the dump algorithm in a subshell and
9237 unset all variables containing newlines (except some which are
9238 special to the shell). Warn about cache variables that are

9254 (AC_LIST_MEMBER_OF): Likewise (renamed to _AC_LIST_MEMBER_IF).
9255 (AC_LINK_FILES): Obsoleted since (and thus AU_DEFUN'ed).

9283 * lib/autoconf/status.m4 (_AC_CONFIG_FOOS): Append TAGS to
9284 ac_config_<foo>s again, sometimes normalized, sometimes not.
9285 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_LINKS):
9286 (AC_CONFIG_COMMANDS): Do not do so here.
9287 (_AC_CONFIG_REGISTER_DEST): Double quote the tags in macros _AC_LIST_TAGS
9288 and_AC_LIST_TAG_COMMANDS; fixes another regression introduced by the
9289 2005-07-25 rewrite. Noticed by Noah Misch.
9291 * lib/autoconf/general.m4 (AC_PRESERVE_HELP_ORDER): Do not define
9292 _AC_PRESERVE_HELP_ORDER, ...
9293 (AC_ARG_ENABLE, AC_ARG_WITH): ... use AC_PROVIDE_IFELSE insetad.
9295 * lib/autoconf/general.m4 (AC_ARG_VAR): Do not use m4_divert_once
9296 inside m4_expand_once; it is redundant.
9298 * lib/autoconf/general.m4 (_AC_INIT_HELP): Remove the broken support
9299 for --help from Cygnus `configure.'
9301 2006-04-06 Paul Eggert <eggert@cs.ucla.edu>

9321 * TODO, config/Makefile.am, lib/freeze.mk, lib/autoconf/c.m4,
9322 lib/autoconf/specific.m4, lib/autoconf/status.m4,
9323 lib/autoconf/types.m4, lib/autotest/general.m4,

9343 normalizing it, consistent it with previous releases.
9344 * tests/torture.at (Macro calls in AC_CONFIG_COMMANDS tags): New test.
9346 2006-04-05 Paul Eggert <eggert@cs.ucla.edu>
9348 * lib/m4sugar/m4sh.m4 (AS_BASENAME_EXPR, AS_DIRNAME_EXPR):
9349 Use simplified args that Eric Blake originally suggested.
9351 2006-04-04 Paul Eggert <eggert@cs.ucla.edu>
9353 * tests/mktests.sh: Don't use 'cat'; just read the files directly.
9354 Prefer 'sort -u' to 'sort | uniq'. Filter data before sorting it.
9355 Use 'comm' rather than N instances of grep; this also fixes a bug
9356 whereby substrings were incorrectly matched, causing us to not
9357 generate tests for AC_F77_NAME_MANGLING and AC_FUNC_LSTAT.
9358 (exclude_list): Exclude empty macros.
9359 (ac_exclude_list): Exclude AC_INCLUDES_DEFAULT.
9361 Use awk rather than grep -E or egrep, to avoid

9442 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't try to
9443 detect exeext, it will be done by _AC_COMPILER_EXEEXT_O; just set
9444 ac_file to the name of the default output file and call
9445 _AC_COMPILER_EXEEXT_WORKS. Move the definition of ac_files and the
9446 initial `rm' of the candidate files...
9447 (_AC_COMPILER_EXEEXT): ... here and simplify them. Moreover, use
9448 the same list in subsequent `rm' calls, and for the temporary

9451 (_AC_COMPILER_EXEEXT_TESTS): ... this new macro.
9452 (_AC_COMPILER_EXEEXT_O): Don't export ac_cv_exeext, it's not needed (or
9453 no longer needed) by libtool. Make it a cache check.
9454 (_AC_COMPILER_EXEEXT_CROSS): Remove the comment, it was obviously
9455 copied here by mistake.

9496 * doc/autoconf.texi (autoreconf Invocation): Document it.
9498 * doc/autoconf.texi: Use `Cygwin', `MinGW', and `license' consistently.

9530 2006-04-01 Stepan Kasal <kasal@ucw.cz>
9532 * bin/autoupdate.in: Handle m4 builtins and m4sugar macros together--
9533 switch all of them on and of when necessary. Fixes the bug when
9534 m4sugar macros (e.g., m4_define) were expanded after the first
9535 automatic update (e.g., after AC_PREREQ or AC_INIT).

10150 CONFIG_SHELL in the environment of the configure rerun.
10151 * doc/autoconf.texi (Here-Documents, config.status Invocation):
10152 Suggest passing CONFIG_SHELL absolute, and in the environment
10153 rather than as option.

10173 * lib/autoconf/programs.m4 (AC_CHECK_PROG, AC_PATH_PROG):
10174 Factor functionality to..
10175 (_AC_CHECK_PROG, _AC_PATH_PROG): these new macros, but only
10176 `AC_SUBST($1)' in the public version.
10177 (AC_CHECK_TOOL, AC_PATH_TOOL, AC_PATH_TARGET_TOOL)
10178 (AC_CHECK_TARGET_TOOL): Use internal versions for ac_ct_* and

10203 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Use conftst2.o instead of
10204 conftest.o, to see whether the compiler really obeys; rm the object
10205 file before and after the test and register it with ac_clean_files.

10228 * doc/autoconf.texi (Generating Sources): AC_LANG_PROGRAMS ->
10229 AC_LANG_PROGRAM, fixing a typo. Don't give details about
10230 the inner workings of AC_LANG_FUNC_LINK_TRY.
10231 * lib/autoconf/c.m4 (AC_LANG_CALL(C)): Reformat to match
10232 AC_LANG_FUNC_LINK_TRY. This involves returning the value returned
10233 by the function rather than ignoring it.
10234 (AC_LANG_FUNC_LINK_TRY(C)): Call the function rather than simply
10235 comparing its address. Intel's interprocedural optimization was
10236 outsmarting the old heuristic. Problem reported by
10239 2005-10-19 Stepan Kasal <kasal@ucw.cz>
10241 * lib/autoconf/general.m4 (AC_SUBST): Remove an obsolete comment.

10248 2005-10-04 Stepan Kasal <kasal@ucw.cz>
10250 * lib/autotest/general.m4 (AT_INIT): Really make the subtree writable
10251 before removing it (chmod -R u+rwx); there are three instances of this.
10253 2005-10-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10254 Stepan Kasal <kasal@ucw.cz>
10256 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Balance parentheses.
10257 * lib/autotest/general.m4 (AT_INIT): If the test dir already exists,
10258 make its content writable before removing it. Remove an errorneous
10259 comment from the end, where the logs of the failed tests are copied
10260 to the main log file.
10262 2005-09-27 Stepan Kasal <kasal@ucw.cz>
10264 * tests/semantics.at (AC_C_BIGENDIAN): Pass --force to autoheader,
10265 in case the computer is too quick. Double quote the configure.ac
10268 * tests/local.at (AT_CHECK_AUTOCONF): Always pass --force to prevent
10269 problems if the testsuite were running too fast.
10271 2005-09-18 Paul Eggert <eggert@cs.ucla.edu>
10273 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Look for X11/Xlib.h
10274 and XrmInitialize rather than X11/Intrinsic.h and XtMalloc
10275 (which belong to Xt, not X itself). See Debian bug 327655.
10276 * NEWS: Mention this.
10278 2005-09-07 Stepan Kasal <kasal@ucw.cz>
10280 * lib/autoconf/c.m4 (AC_LANG_SOURCE(C)): Remove an incorrect comment.
10282 2005-09-06 Paul Eggert <eggert@cs.ucla.edu>
10284 * config/move-if-change: Don't output "$2 is unchanged";
10285 suggested by Ben Elliston. Handle weird characters correctly.
10287 2005-09-06 Stepan Kasal <kasal@ucw.cz>
10289 * lib/autoconf/libs.m4 (AC_SEARCH_LIBS): Merge the two AC_LINK_IFELSE
10290 calls, so that the final expansion of this macro is shorter.
10291 Create the conftest.$ac_ext outside the `for' loop, to speed the run.
10292 Do not use `break' in the argument to AC_LINK_IFELSE, it would skip
10293 the cleanup there. Use AS_VAR_* macros, to be more general.
10294 * tests/semantics.at (AC_SEARCH_LIBS): Check for the cleanup.
10296 * lib/autoconf/general.m4: Use AS_IF where appropriate.
10298 * lib/m4sugar/m4sh.m4 (AS_IF): Use m4_default.
10300 2005-09-01 Stepan Kasal <kasal@ucw.cz>
10302 * doc/autoconf.texi (Configuration Headers): Add an index entry
10305 2005-08-26 Pavel Roskin <proski@gnu.org>
10307 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): Use shell variable

10311 2005-08-26 Paul Eggert <eggert@cs.ucla.edu>
10313 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE):
10314 The previous patch didn't work, so try a better one.
10316 2005-08-26 Stepan Kasal <kasal@ucw.cz>
10318 * doc/autoconf.texi (Programming in M4sh) <AS_TR_CPP>: Fix m4 quoting
10319 in the example. Reported by Bruno Haible.
10320 <AS_TR_SH>: Likewise. Also modify the example to be more convincing:
10321 "if $undefined_var;" succeeds with my shell.
10323 * lib/autoconf/general.m4 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST,
10324 AC_CANONICAL_TARGET): Define by AC_DEFUN, no need to use AC_DEFUN_ONCE;
10325 but change the m4_divert_text to m4_divert_once.
10327 2005-08-25 Paul Eggert <eggert@cs.ucla.edu>
10329 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE):
10330 Work around bug in Solaris /usr/xpg4/bin/awk.
10331 The bug is present in at least Solaris 8 through 10.
10333 2005-08-24 Stepan Kasal <kasal@ucw.cz>
10335 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Simplify; rejecting
10336 some evil values and relying on the fact that $* concatenates the
10337 parameters by the first character from IFS.
10339 2005-08-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
10340 Stepan Kasal <kasal@ucw.cz>
10342 * lib/autoconf/status.m4 (_AC_CONFIG_REGISTER_DEST): When the
10343 first header appears, define AH_HEADER.
10344 * doc/autoconf.texi (Configuration Headers): Document AH_HEADER.
10345 Update limitations about when to call AC_CONFIG_HEADERS.
10346 (Configuration Commands): Document that AC_CONFIG_COMMANDS_PRE
10347 parameter can call AC_SUBST, AC_DEFINE, or AC_CONFIG_FOOS; explain
10348 that AC_CONFIG_COMMANDS_PRE and AC_CONFIG_COMMANDS_POST are not
10349 ``Configuration Actions''; fix their index entries.
10351 * lib/autotest/general.m4 (AT_INIT): Process multiple keywords
10352 options correctly. Process N-M as M-N if M is smaller than N.
10353 Process ranges correctly so that N-N will run only N.
10354 Sort and uniquify the tests that will be run. If there is more
10355 than one test, reinsert the banners for the tests.
10356 * tests/autotest.at (Keywords): Unmark XFAIL.
10358 2005-08-23 Stepan Kasal <kasal@ucw.cz>
10360 * lib/autoconf/general.m4 (_AC_DEFINE_Q): Strip the parameter list
10361 before passing the macro name to AH_TEMPLATE.
10363 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): config.status
10364 now opens log after option processing; in particular, --version
10365 and --help do not touch config.log.
10367 * Makefile.maint: Revert the change from 2005-08-12.
10369 2005-08-22 Stepan Kasal <kasal@ucw.cz>
10371 * lib/autoconf/general.m4 (AC_ARG_ENABLE, AC_ARG_WITH): Factor out

10382 Prepend to LIBS, not append, in examples.
10384 2005-08-16 Stepan Kasal <kasal@ucw.cz>
10386 When building in place, set srcdir="."; suggested by Tim Van Holder.
10388 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Do this; to recognize
10389 build in place, we need ac_pwd, and thus have to AC_REQUIRE ...
10390 (_AC_INIT_DIRCHECK): ... this macro and AC_DEFUN both of them.
10391 * lib/autoconf/status.m4 (_AC_SRCDIRS): Fix a comment: srcdir="."
10392 does not mean "no --srcdir option".
10394 2005-08-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10396 * tests/autoscan.at (autoscan): New file.
10397 * tests/suite.at: Use it.
10398 * tests/Makefile.am (TESTSUITE_HAND_AT): Add it.
10399 Reported against Libtool by Gideon Go <gideon.go@gmail.com>.
10401 * tests/autotest.at (Keywords): Test keywords combinations.
10403 2005-08-12 Stepan Kasal <kasal@ucw.cz>
10405 * Makefile.maint (GZIP_ENV): When checking the help text of gzip,
10406 add "2>&1"; gzip 1.2.4 prints help on stderr.
10408 2005-07-27 Stepan Kasal <kasal@ucw.cz>
10410 * lib/autotest/general.m4 (_AT_DECIDE_TRACEABLE): The symbol at_reason
10411 was pushdef'ed twice while popped only once. Push it only once.
10412 (_AT_CHECK): Cosmetic changes to the "case $at_status" command.
10414 2005-07-26 Stepan Kasal <kasal@ucw.cz>
10416 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): The message is now
10417 prefixed by mere "===", not "configure: === ".
10419 2005-07-25 Paul Eggert <eggert@cs.ucla.edu>
10421 * Makefile.maint: Update from Bison.
10423 * lib/m4sugar/m4sugar.m4 (m4_strip): Comment fix---change tab to
10424 "<tab>" in comment, so that the point is understandable.
10426 2005-07-25 Stepan Kasal <kasal@ucw.cz>
10428 Rewrite substantial part of lib/autoconf/status.m4.
10429 The main change is that CONFIG_FILES, CONFIG_HEADERS, CONFIG_LINKS,
10430 and CONFIG_COMMANDS are not processed in four separate loops.
10431 Instead, there is one main loop. This alows that the common code
10432 is expanded only once, thus config.status (and configure) is smaller.
10434 The registration mechnism in AC_CONFIG_FILES and cousins also changed;
10435 the AC_LIST_FILES and cousins macros are no longer used.
10437 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES, _AC_OUTPUT_HEADERS,
10438 _AC_OUTPUT_LINKS, _AC_OUTPUT_COMMANDS): Renamed to ...
10439 (_AC_OUTPUT_FILE, _AC_OUTPUT_HEADER, _AC_OUTPUT_LINK,
10440 _AC_OUTPUT_COMMAND): ..., respectively. These macros no longer
10441 contain the initialization, nor the for loop, nor the associated
10442 commands; all these go to ...
10443 (_AC_OUTPUT_MAIN_LOOP): ... this new macro, called from
10444 _AC_OUTPUT_CONFIG_STATUS.
10445 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST, _AC_CONFIG_SPLIT_FILE_IN):
10446 Nuked; the code was merged into _AC_OUTPUT_MAIN_LOOP.
10447 (_AC_OUTPUT_FILE): The creation of the sed script ...
10448 (AC_OUTPUT): ... and the setup of ac_vpsub goes to ...
10449 (_AC_OUTPUT_FILES_PREPARE): ... a new macro, also called from
10450 _AC_OUTPUT_MAIN_LOOP.
10451 (_AC_CONFIG_FILES, _AC_CONFIG_HEADERS, _AC_CONFIG_LINKS,
10452 _AC_CONFIG_COMMANDS): Use ...
10453 (_AC_CONFIG_FOOS): ... this new macro, which uses these ...
10454 (_AC_CONFIG_REGISTER, _AC_CONFIG_REGISTER_DEST): ... new macros.
10455 (_AC_CONFIG_FILE, _AC_CONFIG_HEADER, _AC_CONFIG_LINK,
10456 _AC_CONFIG_COMMAND, _AC_CONFIG_DEPENDENCIES): No longer needed.
10457 (_AC_CONFIG_DEPENDENCY): Update, it uses these ...
10458 (_AC_CONFIG_DEPENDENCY_DEFAULT, _AC_FILE_DEPENDENCY_TRACE_COLON):
10460 (_AC_CONFIG_UNIQUE): Update.
10461 (AC_LIST_FILES, AC_LIST_HEADERS, AC_LIST_LINKS, AC_LIST_COMMANDS):
10462 Replaced by this ...
10463 (_AC_LIST_TAGS): ... new common macro.
10464 (AC_LIST_FILE_COMMANDS, AC_LIST_HEADER_COMMANDS, AC_LIST_LINK_COMMANDS,
10465 AC_LIST_COMMAND_COMMANDS): Replaced by this ...
10466 (_AC_LIST_TAG_COMMANDS): ... new common macro.
10467 (_AC_CONFIG_COMMANDS_INIT): Moved top to the `registration' section;
10468 this didn't belong to the `config commands' section.
10469 (_AC_OUTPUT_COMMANDS_INIT): Don't initialize, m4_ifdef is our friend.
10470 (AC_CONFIG_COMMANDS_PRE, AC_OUTPUT_COMMANDS_PRE,
10471 AC_CONFIG_COMMANDS_POST): Moved to a new section, these didn't belong
10472 to the `config commands' section either.
10473 (AC_CONFIG_SUBDIRS): Don't touch diversion DEFAULTS.
10474 (_AC_LIST_SUBDIRS): Don't initialize, m4_ifdef is our friend.
10476 ... and many changes to the comments nearby.
10478 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): At the end of the day,
10479 set ac_subdirs_all='_AC_LIST_SUBDIRS'.
10480 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
10481 AC_CONFIG_COMMANDS(command:input,...) is no longer allowed.
10482 (#define header templates): The comment at the top of the generated
10483 header now includes the name(s) of the source file(s).
10485 Several unrelated small changes:
10487 * lib/autoconf/general.m4 (AC_CACHE_VAL): Be didactic, quote the first
10488 parameter to AC_DIAGNOSE.
10489 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS): Likewise.
10490 (_AC_LINK_FILES_CNT): Don't AU_DEFUN this; it causes confusing messages
10491 with autoupdate; use m4_define_default inside AU_DEFUNed AC_LINK_FILES.
10492 (AC_OUTPUT): In the compatibility code, use m4_ifvaln, to be consistent
10493 with AU::AC_OUTPUT.
10494 (AU::AC_OUTPUT): Don't double-quote $2 and $3, the compatibility code
10495 in AC_OUTPUT doesn't double-quote it either.
10496 * tests/tools.at (autoupdate): AU::AC_OUTPUT no longer double-quotes the
10499 2005-07-10 Stepan Kasal <kasal@ucw.cz>
10501 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Document which
10502 versions of Portland Group compiler produce single- and double-quoted
10503 -cmdline argument. Reported by Steven G. Johnson <stevenj@fftw.org>
10504 and Ole Holm Nielsen <Ole.H.Nielsen@fysik.dtu.dk>.
10506 2005-07-07 Paul Eggert <eggert@cs.ucla.edu>
10508 * tests/local.at (AT_CONFIG_CMP): Ignore lines like "LIBS=''" too.
10509 This is a corrected version of yesterday's patch.
10511 2005-07-07 Stepan Kasal <kasal@ucw.cz>
10513 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Report the full
10514 path, too; insert a "===" to emphasize the line.
10516 * lib/autoconf/general.m4 (AC_CANONICAL_BUILD): Rename
10517 ac_cv_build_alias to ac_build_alias.
10518 (AC_CANONICAL_HOST, AC_CANONICAL_TARGET): Simplify.
10520 On 2005-02-24, an unintentional AC_SUBST([CC]) was introduced; this
10521 change eliminates it. Problem reported by Alexandre Duret-Lutz.
10522 * lib/autoconf/general.m4 (_AC_ARG_VAR_PRECIOUS): Move the AC_SUBST ...
10523 (AC_ARG_VAR): ... here.
10524 (_AC_INIT_PREPARE): Call AC_SUBST for build_alias, host_alias and
10527 Keep a list of all precious variables and process them with one simple
10528 for loop, instead of expanding all commands, or, OTOH, complicated
10529 processing of output of "set".
10530 * lib/autoconf/general.m4 (_AC_ARG_VAR_PRECIOUS): Acumulate the
10531 variable names in new macro...
10532 (_AC_PRECIOUS_VARS): ... which will be assigned to ac_precious_vars.
10533 (_AC_ARG_VAR_STORE): New macro which writes to diversion PARSE_ARGS
10534 a loop to assign all ac_env_* and ac_cv_env_* variables.
10535 (_AC_ARG_VAR_VALIDATE): Use shell variable ac_precious_vars, divert
10537 (_AC_INIT_DEFAULTS): At the end, if _AC_PRECIOUS_VARS is set, assign
10538 its value to shell variable ac_precious_vars and call
10539 _AC_ARG_VAR_STORE and _AC_ARG_VAR_VALIDATE.
10540 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Don't call
10541 _AC_ARG_VAR_VALIDATE.
10543 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Move AC_LANG_PUSH(C)
10544 and the AC_SUBSTs ...
10545 (AC_INIT): ... here.
10547 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Changed the title of

10566 Fix my changes from 2005-07-01; reported by Noah Misch.
10567 * lib/autoconf/status.m4 (_AC_CONFIG_DEPENDENCIES): Fix the
10568 description, the macro now accepts only a single tag.
10569 (_AC_CONFIG_UNIQUE): Likewise; s/AC_File/[$1]/
10571 Fix cases when the varsions of Autoconf and Autotest don't match.
10572 Reported by Noah Misch.

10586 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Use &, not |, in
10587 sed substitution command, so that we allow | in program prefixes

10598 for loop over config.site files using `set', to allow
10599 directory names containing IFS characters.
10601 2005-07-01 Paul Eggert <eggert@cs.ucla.edu>
10603 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Remove the tests for
10604 directories with weird names. Apparently some people like living

10625 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Use a here
10626 document to output the default config_* lists to config.status.
10627 Don't recognize option --file, if the functionality is not there.
10628 Likewise for --header; moreover, recognize --he and --h as shortcuts
10629 for --help in that case.
10631 * lib/autoconf/status.m4: Fix the order of the "sections", so that it
10632 matches the order of execution. No code changed.

10651 * lib/autoconf/general.m4 (AC_ARG_VAR): Move next to _AC_ARG_PRECIOUS.
10653 * lib/autoconf/general.m4 (AC_SUBST_TRACE): New macro, to be traced
10654 instead of AC_SUBST; proposed by Alexandre Duret-Lutz.
10655 (AC_SUBST): Call it.
10656 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Call AC_SUBST_TRACE for
10657 the directory specific variables; but don't call it for configure_input.
10659 2005-06-28 Derek Price <derek@ximbiot.com>
10661 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: Reword recent
10664 2005-06-23 Paul Eggert <eggert@cs.ucla.edu>
10666 * NEWS: Don't worry about spaces in bindir etc. Only srcdir and working
10667 directory have inherent problems with special characters like spaces,
10668 due to limitations in Make syntax. Problem reported by Alexandre
10670 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Implement the above.
10671 Also, fix Tru64 porting problem with shell patterns,

10683 from Justace Clutter.
10684 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Put name of invalid
10685 variable into diagnostic. Make the diagnostic an error, not a warning,
10686 because we really don't support spaces and suchlike in dir names.
10687 (_AC_INIT_SRCDIR): Allow special characters in $ac_unique_file.
10688 Don't worry about backslashes in srcdir; it can't happen now.

10699 (AT_CONFIG_CMP): Use sed instead of grep plumbing.
10701 * doc/autoconf.texi (Limitations of Usual Tools) <grep>: Mention
10702 that '\|' is not allowed in BREs; recommend using newline separated
10703 list of patterns instead of multiple -e options.

10715 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: Document that
10716 b, t, r, w commands require single space, while : cannot have any.
10717 (Special Shell Variables): Fix sed code this in the example.
10718 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Likewise; and fix a typo.
10719 * lib/autotest/general.m4 (AT_ARG_OPTION): Fix typo in the description.
10721 * lib/m4sugar/m4sugar.m4 (m4_split): If the parameter is empty,
10722 expand to the empty list. Don't use two pairs of m4_changequote,
10723 it's not necessary.
10725 2005-06-20 Derek Price <derek@ximbiot.com>
10727 * lib/m4/programs.m4 (AC_PROG_YACC): Declare YACC & YFLAGS precious.
10729 2005-06-17 Paul Eggert <eggert@cs.ucla.edu>
10731 * lib/m4sugar/m4sh.m4 (as_awk_strverscmp): Port to Solaris /bin/awk.
10732 * doc/autoconf.texi:
10733 Don't mention Solaris versions so much, if a
10734 problem is common to all extant versions of Solaris. Say "SunOS
10735 4" instead of "SunOS" for SunOS 4.
10736 (awk): Mention more of the limitations of traditional Awk.
10737 (cat): Don't talk about cat -v.
10739 2005-06-16 Paul Eggert <eggert@cs.ucla.edu>
10741 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE): New macro.

10744 to be compatible with glibc strverscmp.
10745 * tests/m4sh.at (AS_VERSION_COMPARE): New test.
10747 * doc/autoconf.texi (Limitations of Usual Tools): Mention expr bug

10750 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT):
10751 Use shell builtins rather than 'expr', to work around expr bug.
10753 2005-06-10 Paul Eggert <eggert@cs.ucla.edu>
10755 * doc/autoconf.texi: "filesystem" -> "file system".
10756 "behaviour" -> "behavior".

10758 * lib/autoconf/general.m4: Omit blank after ":" sed command,
10760 * lib/m4sugar/m4sh.m4: Likewise.
10761 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Work around problem
10762 with Solaris sed. Fix by Ralf Menzel and Stepan Kasal.

10765 (.x.1): Ignore the time stamp in the .TH line when deciding whether
10766 to update the man page. That way, we don't have to check in new
10767 man pages every month.
10769 * lib/m4sugar/m4sh.m4 (AS_VAR_TEST_SET): Work even if $1 contains
10770 quotes and backslashes. Patch from Derek Price.

10780 -u, since it outputs chatter if the input files are the same.
10781 Problem reported by Ralf Menzel.
10783 2005-06-08 Derek Price <derek@ximbiot.com>
10785 * lib/m4sugar/m4sugar.m4: Undefine include & sinclude rather than
10786 renaming them since they are about to be redefined anyhow.
10788 2005-06-08 Derek Price <derek@ximbiot.com>
10790 * doc/autoconf.texi (Redefined M4 Macros): Add index entries for most
10791 redefined M4 macros to this node. Document m4_include & m4_sinclude.
10792 Move m4_undefine to alphabetical order.
10794 2005-06-07 Paul Eggert <eggert@cs.ucla.edu>
10796 * README: Recommend GNU M4 1.4.3 or later.
10797 * doc/autoconf.texi (Introduction): Likewise.
10798 Reword to avoid some formatting glitches.
10799 Use "#!/bin/sh", not "#! /bin/sh"; the space isn't needed these days.
10800 Clarify explanation of HP compiler bug.
10801 Redo example output tp match current CVS snapshot.
10802 Use @example.org in email addresses when the examples
10803 might get inadvertently cut-and-pasted into user code.
10804 Remove example of autom4te usage that doesn't seem to work now.
10805 Use modern AC_INIT (except when the example is meant to be
10806 shown with Autoconf 2.13).
10807 Update ksh info for Solaris 9 and later.
10809 Modernize description of Automake versions a bit.
10810 Don't claim a future version of Autoconf is near.
10811 * doc/install.texi: Reword to avoid some formatting glitches.
10813 2005-06-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10815 * doc/autoconf.texi: Add [] to examples, so that the manual
10816 follows its own advice about quoting better.
10817 Reword to avoid some formatting glitches.
10818 * doc/installt.exi: Reword to avoid some formatting glitches.
10820 * doc/autoconf.texi (Limitations of Builtins) <case>: Mention
10821 Tru64 ksh pattern matching bug. Reported against Libtool by
10822 Albert Chin <libtool@mlists.thewrittenword.com> and
10823 Nicolas Joly <njoly@pasteur.fr>.
10825 2005-06-06 Stepan Kasal <kasal@ucw.cz>
10827 m4_cdr of one-member list was [[]] (one-member list containing an
10828 empty string) instead of [] (an empty list. Callers were skewed to
10829 match this misbehaviour. As a consequence of this:
10830 - m4_foreach([x], [], [foo]) expanded to `foo', while
10831 - the expansion of m4_foreach([x], [[]], [foo]) was empty.
10832 This bug has been fixed:
10834 * lib/m4sugar/m4sugar.m4 (m4_cdr): If only one argument is given,
10835 expand to an empty string; print error msg if called without
10837 (m4_foreach, m4_map, m4_map_sep): Don't expect the previous
10838 misbehaviour; handle [] and [[]] correctly.
10840 2005-06-06 Stepan Kasal <kasal@ucw.cz>
10842 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Nuke ac_max_here_lines.
10843 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Simplify the sed
10844 scripts created and the loop applying them, use _AC_SED_CMD_LIMIT.
10846 2005-06-06 Ralf Menzel <menzel@ls6.cs.uni-dortmund.de> (trivial change)
10848 * doc/autoconf.texi (Limitations of Usual Tools): Solaris' awk cannot
10849 swallow records with more than 99 fields.
10850 * lib/autotest/general.m4 (AT_INIT): Use the awk builtin `split' to
10851 parse the long line.
10853 2005-06-04 Stepan Kasal <kasal@ucw.cz>
10855 * doc/autoconf.texi (Limitations of Usual Tools): AIX awk cannot
10856 swallow literals longer than 399. Reported by Ralf Wildenhues.
10857 * lib/autotest/general.m4 (AT_INIT): Pass $at_groups though stdin,
10858 to workaround this limitation.

10868 * tests/Makefile.am (check_SCRIPTS): Set to $(wrappers).
10869 (DISTCLEANFILES): Remove $(check_SCRIPTS).

10874 * lib/autotest/general.m4 (AT_INIT): Don't create a regular
10875 expression of unbounded size when processing the --list
10876 option. This runs afoul of a limit of 399 bytes per regular
10877 expression on AIX. Problem reported by Ralf Wildenhues.

10888 2005-05-31 Dan Manthey <dan_manthey@partech.com>
10890 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Output variables may
10891 now contain newlines, and substituted files must be referenced on
10892 a line alone; the sed scripts to substitute them are now very
10894 (_AC_SED_CMD_LIMIT): Added; single place to store limit on how many
10895 commands can be put in a sed script portably.
10896 * doc/autoconf.texi (Setting Output Variables): Document above
10897 changes. (Particular Header Checks) <AC_HEADER_STDBOOL>: Give exaple

10908 * tests/local.at: Don't attempt to check for negated character
10909 classes in shell scripts. The test was too brittle.
10911 2005-05-25 Stepan Kasal <kasal@ucw.cz>
10913 * bin/autoconf.as: Don't use "shift 2"; it's not portable enough.

10927 messages when ac_unique_file is not found.
10928 (AC_CONFIG_MACRO_DIR): Simplify the `if' at the end.
10929 (AC_MSG_CHECKING, AC_MSG_RESULT): Put braces around the two echo
10930 commands, for consistency with AC_MSG_ERROR and such.
10932 * bin/autoconf.as: Make more use of "shift 2" in option processing.

10947 (ac_top_build_prefix): ... to this; the old name is also kept, for
10948 backward compatibility.
10949 (ac_top_builddir_sub): New variable, without the trailing slash,

10965 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Don't m4_quote the second
10966 argument to m4_foreach. I guess it was necessary in the past,
10967 but I think it's a no-op now.

10971 * lib/autoconf/general.m4 (_AC_INIT_HELP): Merge two consecutive
10972 ``cat <<_ACEOF'' commands to one.

11046 abbreviations of --version and --debug.
11048 2005-05-10 Paul Eggert <eggert@cs.ucla.edu>
11050 * doc/autoconf.texi (Autoconf Language): Be more precise about
11051 quoting rules. Problems noted by Stepan Kasal.
11052 Also, throughout this document, be more careful about white space.
11053 "blank", "white space", and "space" all have different meanings
11054 and we should be careful to say what we mean.
11056 2005-05-05 Paul Eggert <eggert@cs.ucla.edu>

11071 2005-05-02 Gary V. Vaughan <gary@gnu.org>
11073 * lib/autoconf/general.m4 (_AC_LIBOBJS_NORMALIZE): Prepend each
11074 object named in LIBOBJS and LTLIBOBJS with the ${LIBOBJDIR}, as
11075 set by latest automake.
11077 2005-05-01 Paul Eggert <eggert@cs.ucla.edu>
11079 * doc/autoconf.texi (Limitations of Usual Tools): "expr '' \| ''"
11080 outputs 0 on GNU/Linux these days.
11082 2005-04-29 Paul Eggert <eggert@cs.ucla.edu>
11084 * doc/autoconf.texi (Autoconf Language): Add more description
11085 about quoting heuristics.
11086 (Limitations of Builtins): Describe "set -" problems.
11088 2005-04-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11090 * lib/autotest/general.m4 (AT_KEYWORDS): Separate by space,
11093 * doc/autoconf.texi (External Software): Replace AC_DEFINE_UNQUOTED
11094 by AC_DEFINE; it was a mistake.
11095 From bug reported against libtool by Dalibor Topic <robilad@kaffe.org>.
11097 2005-04-25 Stepan Kasal <kasal@ucw.cz>
11099 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): A tiny optimization.
11101 2005-04-22 Stepan Kasal <kasal@ucw.cz>
11103 * doc/autoconf.texi (External Software): Quadrigraphs are not
11104 processed correctly in AS_HELP_STRING; avoid this in the examples.
11105 * lib/m4sugar/m4sh.m4 (AS_HELP_STRING): Add a FIXME about quadrigraphs.
11106 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Likewise; and rephrase the
11107 comment and reduce m4_default([foo], []) to [foo].
11108 (m4_strip): Update the explanation.
11110 2005-04-19 Paul Eggert <eggert@cs.ucla.edu>
11112 * lib/autoconf/general.m4 (_AC_INIT_PREPARE, _AC_RUN_IFELSE):
11113 Remove core.conftest.* too; it's generated by Tru64 5.1.
11114 Problem reported by Jennis Pruett.
11115 * lib/autoconf/functions.m4
11116 (AC_FUNC_SETVBUF_REVERSED, AC_FUNC_UTIME_NULL):
11117 Don't bother to remove core files; AC_RUN_IFELSE should do that
11120 2005-04-19 Stepan Kasal <kasal@ucw.cz>
11122 * lib/m4sugar/m4sugar.m4 (m4_bpatsubsts): Add the b- to comment, too.

11136 * doc/autoconf.texi (External Software, Package Options): Add
11137 examples showing how to implement --with-* and --enable-* options.
11139 2005-04-13 Paul Eggert <eggert@cs.ucla.edu>
11141 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Look for configure.ac
11142 as well as configure.in. Problem reported by Gregorio Guidi.
11144 2005-04-10 Paul Eggert <eggert@cs.ucla.edu>
11146 * doc/autoconf.texi (Particular Functions): Use gnulib's current
11147 pattern for alloca snippet.

11160 fails if %s isn't supported. Problem reported by Ralf Wildenhues.
11162 2005-03-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11164 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS):
11165 Merge `-z option' as well for the benefit of Solaris link flags. Pass
11166 whole-archive (-zallextract, -zdefaultextract) options in the hope of
11167 unique libraries, for the Sun Fortran 95 8.0 compiler. Bug reported
11168 against Libtool by Yury Puhalsky <pooh@cryptopro.ru>.
11170 2005-03-22 Paul Eggert <eggert@cs.ucla.edu>
11172 * NEWS: The configure command now warns you if you attempt to use
11173 a directory whose name contains a special character like space,
11175 * doc/autoconf.texi (Installation Directory Variables): Allow
11176 "," in file names. Do not use \@; it's not a portable regexp.
11177 * bin/Makefile.am (edit): Likewise.
11178 * lib/Makefile.am (edit): Likewise.
11179 * tests/Makefile.am (edit): Likewise.
11180 * tests/semantics.at: Likewise.

11182 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Likewise.
11183 * lib/autoconf/status.m4 (_AC_SRCDIRS): Likewise.
11184 * doc/autoconf.texi (File System Conventions): Warn about
11185 unportable file names.
11186 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): New macro.
11188 (_AC_INIT_SRCDIR): Use ac_pwd rather than invoking pwd.
11189 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Propagate
11190 ac_pwd, and quote srcdir.
11191 * lib/autotest/general.m4 (AT_INIT): Quote file name args.
11193 * doc/autoconf.texi: Fix some systematic formatting problems.
11194 ".)" needs a following @: if not at the end of a sentence, and
11195 similarly for "!)". "etc." should be preceded by a comma.
11196 "n-th" -> "@var{n}th". pdksh is still buggy, so update its date.
11198 2005-03-22 Bruno Haible <bruno@clisp.org>
11200 * doc/autoconf.texi (Input): Mention that AC_CONFIG_AUX_DIR's
11201 argument is often called 'build-aux'.
11203 2005-03-07 Stepan Kasal <kasal@ucw.cz>
11205 * doc/autoconf.texi (Quotation Rule Of Thumb): Mention that the
11206 macro AC_TRY_LINK is obsolete.
11207 (Installation Directory Variables): Change `AC_OUTPUT_FILES' to
11210 2005-02-24 Stepan Kasal <kasal@ucw.cz>
11212 * lib/autoconf/c.m4 (AC_PROG_CC): Be more careful to skip
11213 `/usr/ucb/cc'; use `cl.exe' to distinguish the MS compiler
11214 from a Common Lisp's `cl'.
11215 (AC_PROG_CXX): Behave according to the documentation: don't
11216 search for $ac_tool_prefix$CCC and $CCC, just set CXX=$CCC;
11217 make the variable CCC precious; use `cl.exe', not `cl'.
11219 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
11220 Alexandre Duret-Lutz <adl@gnu.org>
11222 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin from
11223 /dev/null, as "configure" shouldn't read stdin, and this insulates
11224 us from problems (e.g., when testing for "cl"). Also, do this
11225 redirection before invoking "hostname" or "uname", and keep the
11226 original input stream available via...
11227 (AS_ORIGINAL_STDIN_FD): ... this new macro.
11228 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't
11229 bother with "</dev/null" since it's now done at the top of
11231 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Likewise.
11232 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
11233 * lib/autoconf/programs.m4 (_AC_PATH_PROG_FLAVOR_GNU): Likewise.

11236 * tests/base.at (Input/Output): New test.
11238 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
11240 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N_PREPARE): Don't set ECHO_C to
11241 newline if neither \c nor -n work, as that would output two
11242 newlines. Prefer -n to \c. Reported by Stepan Kasal.
11244 2005-02-12 Stepan Kasal <kasal@ucw.cz>
11246 * lib/m4sugar/m4sh.m4 (AS_IF): Define by m4_defun, not m4_define.
11247 This causes that any required macros inside will get before the if.
11248 * doc/autoconf.texi (autom4te.cache): A typo.
11250 2005-02-12 Paul Eggert <eggert@cs.ucla.edu>
11252 Undo previous change, except keep the change to
11253 lib/autoconf/programs.m4 that replaced grep with shell
11254 pattern-matching. This is because net-snmp configure reads stdin.
11255 Reported by Noah Misch.
11257 2005-02-11 Paul Eggert <eggert@cs.ucla.edu>
11259 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin
11260 from /dev/null, as "configure" shouldn't read stdin, and this
11261 insulates us from problems (e.g., when testing for "cl").
11262 Suggested by Alexandre Duret-Lutz. Also, do this redirection
11263 before invoking "hostname" or "uname".
11264 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
11265 _AC_LINK_IFELSE): Undo previous change, as it's no longer needed.
11266 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Don't bother with
11267 "</dev/null" since it's now done at the top of 'configure'.
11268 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
11269 * lib/autoconf/programs.m4 (_AC_PATH_PROG_FLAVOR_GNU): Likewise.
11270 Also, replace grep with shell pattern-matching, to save a process.
11272 2005-02-10 Paul Eggert <eggert@cs.ucla.edu>
11274 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
11275 _AC_LINK_IFELSE): Redirect stdin to /dev/null, in an attempt to
11276 avoid thinking that Allegro Common Lisp's "cl" command is a C++
11279 2005-02-09 Paul Eggert <eggert@cs.ucla.edu>
11281 * doc/autoconf.texi (Limitations of Usual Tools): Document that
11282 grep -q isn't portable. Improve grep -s explanation.
11283 Problem reported by Dan Manthey.
11285 2005-02-08 Paul Eggert <eggert@cs.ucla.edu>
11287 * doc/autoconf.texi (Special Shell Variables): Clarify
11288 PATH_SEPARATOR wording; fix typo in IFS. Reported by Gary V. Vaughan.
11290 2005-02-07 Paul Eggert <eggert@cs.ucla.edu>
11292 * doc/autoconf.texi: Use @acronym for DJGPP.
11293 Fix some @code's that should have been @env's, and vice versa.
11294 Sort environment variable names.
11295 Mention that shells no longer inherit IFS.
11296 Don't recommend PATH_SEPARATOR=';' so strongly.
11297 Mention that $RANDOM might expand to the empty string.
11298 "symlink" and "soft link" -> "symbolic link".
11299 Improve mktemp description (reported by Bruno Haible).
11301 2005-02-05 Paul Eggert <eggert@cs.ucla.edu>
11303 * tests/foreign.at (Libtool): Don't overquote AT_SETUP arg.
11304 * tests/m4sh.at (AS_DIRNAME, AS_BASENAME, AS_MKDIR_P, AS_HELP_STRING):
11306 * tests/semantics.at (AC_C_BIGENDIAN, AC_PATH_PROG & AC_PATH_PROGS):
11309 2005-02-04 Paul Eggert <eggert@cs.ucla.edu>
11311 * NEWS: Mention AT_COPYRIGHT.
11313 * tests/local.at (AT_CMP): Use diff directly on input files rather
11316 * lib/autoconf/programs.m4 (AC_PROG_SED): Don't look in
11317 /usr/xpg4/bin since that sed dumps core (at least on Solaris 8).
11319 2005-02-04 Noah Misch <noah@cs.caltech.edu>
11320 and Paul Eggert <eggert@cs.ucla.edu>
11322 * tests/autotest.at (Empty test suite): New test.
11323 * tests/torture.at (Substitute and define special characters)
11324 (Substitute a 2000-byte string, Define to a 2000-byte string)
11325 (Substitute a newline, Define a newline): New tests.
11327 2005-02-04 Noah Misch <noah@cs.caltech.edu>
11329 * lib/m4sugar/m4sugar.m4 (m4_re_string, m4_re_word): Revert 2002-03-04.
11330 * tests/local.at (AT_CHECK_M4SUGAR): Add `m4sugar' to keywords.
11331 (AT_CHECK_ENV): Ignore LTLIBOBJS, FC variables, EGREP, FGREP, and SED.
11332 * tests/m4sugar.at (AT_CHECK_M4SUGAR_TEXT, AT_CHECK_M4RE): New macros.

11334 (m4_warn, m4_require: circular dependencies, m4_text_wrap): Strip
11335 excess test name quoting.
11336 * tests/semantics.at (AC_CHECK_HEADERS_OLD, AC_CHECK_HEADERS_NEW): Pass
11337 CPPFLAGS to `configure' instead of setting it in `configure'.
11339 * lib/m4sugar/m4sh.m4 (AS_UNAME): Try only /usr/bin/hostinfo, not
11340 any `hostinfo' in $PATH, since hostinfo.exe is a popular file name
11343 * lib/autoconf/fortran.m4 (AC_LANG(Fortran), AC_FC_SRCEXT):
11344 s/FC_SRCEXT/ac_fc_srcext/; s/FCFLAGS_SRCEXT/ac_fcflags_srcext/.
11346 * tests/local.at (AT_CMP): New macro.
11347 (AT_DATA_AUTOCONF): Do not call AC_PROG_GREP.
11348 (AC_SAVE_STATE): Move environment grep...
11349 (AT_CHECK_ENV): to here. Filter out `'$''. Use AT_CMP.
11350 (AT_CONFIG_CMP): New macro.
11351 (AT_CHECK_MACRO): Run `configure' twice with cache and compare results.
11352 * tests/c.at (Extensions): Do not exit early.
11353 * tests/atlocal.in: Inherit $GREP.
11355 * lib/autoconf/c.m4 (_AC_C_STD_TRY): New macro.
11356 (_AC_PROG_CC_C89, _AC_PROG_CC_C99): Use it.
11358 * lib/autoconf/general.m4 (_AC_INIT_COPYRIGHT): Update for 2005.
11359 (AC_COPYRIGHT): Factor header comment portion out and move into...

11372 2005-02-03 Paul Eggert <eggert@cs.ucla.edu>
11374 * lib/m4sugar/m4sugar.m4 (m4_re_escape): Escape ?, ^, \, $ too;
11375 this fixes a bug tickled by the AT_CAPTURE_FILE change noted below.
11377 Try not to generated lines of unlimited length, as POSIX places a
11378 2047-byte limit on line length of portable text files.
11379 * lib/autoconf/general.m4 (AC_SUBST, AC_SUBST_FILE):
11380 Use newline as a separator, not space.

11385 2005-02-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11387 * lib/m4sugar/m4sh.m4 (_AS_SHELL_FN_WORK): Move func_* to
11388 as_func_*. Add test to check whether positional parameters
11389 are restored after function return.
11391 2005-02-02 Paul Eggert <eggert@cs.ucla.edu>
11393 * doc/autoconf.texi (Special Shell Variables): Mention _,
11394 BIN_SH, DUALCASE. Say that variables other than "status" are safe
11395 if they contain a lower-case letter. The DUALCASE problem was
11396 reported by Ralf Wildenhues.
11398 * bin/autoconf.as: Don't exit with status 0 after write failure
11399 with --help or --version.
11400 * lib/autoconf/general.m4 (_AC_INIT_HELP, _AC_INIT_VERSION): Likewise.
11401 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Likewise.

11405 * doc/autoconf.texi (Limitations of Usual Tools):
11406 Unicos 9 sed limitations.
11407 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Try cf77 before fort77
11408 to get the option-enhanced interface on older Crays. Try ftn for
11409 Fortran 95 (newer Crays).
11411 2005-02-01 Paul Eggert <eggert@cs.ucla.edu>
11413 * man/Makefile.am (.x.1): Go back to the simple solution, but take
11414 care to echo the commands, so the user knows what's going on.
11415 Modified from a suggestion by Stepan Kasal.
11417 * doc/autoconf.texi (autoreconf Invocation): Mention autopoint,
11418 with a cross reference. Derived from a suggestion by Bruce Korb.

11422 * doc/autoconf.texi (config.status Invocation): Warn about
11423 discrepancy between CONFIG_SHELL and shell used to invoke 'configure'.

11425 Based on a proposed patch by Ralf Wildenhues.
11427 * man/Makefile.am (.x.1): Make sure the required generated files
11428 are up to date. Problem and original solution proposed by Stepan Kasal.

11438 Simplify the implementation of m4_require (a.k.a. AC_REQUIRE).
11439 Update the long comment explaining it.
11441 m4_require no longer writes an ``is required by'' line to the
11442 execution stack. It contains only one bit of non-redundant
11443 information: that the macro was required, not called. And even
11444 this bit is useless in most situations: have you ever met a macro
11445 which both calls and requires the same macro?
11447 * lib/m4sugar/m4sugar.m4 (_m4_defun_pro): Don't push a diversion...
11448 (_m4_defun_pro_outer): ... only via this macro, for the outermost

11451 (m4_expansion_stack_pop): Remove the misplaced comment.
11452 (m4_require): Don't put the ``is required by'' line to the
11453 execution stack; slightly improve the out-of-a-defun error message.

11455 (_m4_require_call): Use it.
11456 * tests/m4sugar.at (m4_require): Expect output without the
11457 ``is required by'' messages.

11493 2005-01-20 Paul Eggert <eggert@cs.ucla.edu>
11495 * doc/autoconf.texi (Shell Substitutions): Fix typo in case statement.
11496 Warn about newline stripping in `` and $(). Update Solaris

11525 2005-01-05 Alexandre Duret-Lutz <adl@gnu.org>
11527 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Define datarootdir,

11552 (m4_divert, m4_divert_push, m4_divert_pop, m4_init): Use it.
11553 (m4_divert_push, m4_divert_pop, _m4_defun_epi): Don't expand the word
11554 stored in _m4_divert_diversion or _m4_divert_dump.
11555 (m4_divert_pop): When the parameter is given, compare the symbolic
11556 name with the last diversion pushed on the stack. Previously, the
11557 current diversion was compared with the numeric value of the
11558 diversion given as the parameter.
11559 (m4_require): If the macro hasn't been expanded yet, call ...

11593 * bin/autoreconf.in (autoreconf_current_directory): AM_INIT_AUTOMAKE

11646 * lib/autoconf/status.m4: Quote ``$tmp'' in many places.

11843 <http://lists.gnu.org/archive/html/autoconf/2004-12/msg00074.html>.
11844 Don't use "set - x"; plain "set x" is enough, and simplifies debugging.
11846 2004-12-07 Stepan Kasal <kasal@ucw.cz>
11848 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT): Fix typo in previous

11863 with exactly one parameter.
11865 2004-12-02 Paul Eggert <eggert@cs.ucla.edu>
11867 * lib/autoconf/functions.m4 (AC_FUNC_MEMCMP): Use
11868 "char c = '\200';" rather than "char c = 0x80;" as the
11869 latter doesn't conform to the strict C standard due to

11872 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Prefer -qlanglvl=extc89

11973 Problem reported by Stepan Kasal.
11975 2004-09-05 Paul Eggert <eggert@cs.ucla.edu>

11979 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Set SHELL=/bin/sh
11981 * lib/autotest/general.m4 (AT_INIT): Don't assume /dev/null is

11984 2004-09-04 Paul Eggert <eggert@cs.ucla.edu>
11986 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): If xmkmf returns
11987 "/usr/include", clear ac_x_includes instead of leaving it as "no"
11988 (trivial change). Problem and patch reported by Andrew Church in:
11989 http://lists.gnu.org/archive/html/bug-autoconf/2004-04/msg00016.html
11991 2004-09-03 Paul Eggert <eggert@cs.ucla.edu>

12021 Remove ansi2knr.c; nobody uses it.
12022 (ansi2knr.c-url_prefix): Remove.
12023 (cvs-update): Fix test for failure. I don't know why it ever
12026 * doc/autoconf.texi: Update URLs, some of which went stale.
12027 Use @uref rather than @href.
12029 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Have configure
12030 handle "--" as per POSIX. Suggested by Paul Pogonyshev.
12032 * config/config.guess, config/config.sub, config/elisp-comp,
12033 config/install-sh, config/mkinstalldirs, config/texinfo.tex,

12043 tests/tools.at, tests/torture.at:
12044 Use "file name" rather than "filename" or "path",
12045 to be consistent with the terminology of the GNU coding standards.
12047 2004-08-19 Paul Eggert <eggert@cs.ucla.edu>
12049 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C),
12050 AC_C_LONG_DOUBLE): Undo 2004-06-04 change, as it didn't work with
12051 HP-UX 11.23 cc/aCC or Tru64 4.0 cc. Problem reported by Noah Misch in
12052 <http://lists.gnu.org/archive/html/autoconf/2004-07/msg00004.html>.
12054 More fixes to support spaces in the name of the build directory.
12055 This isn't a complete fix but it's an improvement.
12057 * bin/autoconf.as (autom4te_options): New var.
12058 Use it instead of appending to AUTOM4TE, so that we can allow
12059 spaces in the build directory's absolute name.
12060 * bin/autoheader.in ($autoconf): Allow spaces in file names.
12061 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP, _AT_CHECK,
12062 AT_CHECK_NOESCAPE): Likewise.
12063 * tests/wrapper.as (testdir, AUTOM4TE_CFG, autom4te_perllibdir,
12064 main program): Likewise.
12066 2004-08-18 Paul Eggert <eggert@cs.ucla.edu>
12068 * lib/autoconf/general.m4 (_AC_INIT_HELP): Quote $ac_popdir uses.

12074 * doc/autoconf.texi (Function Portability): Document isinf and
12075 and isnan. From a suggestion by Kevin Ryde.
12077 * lib/Autom4te/General.pm (END): Return correct exit status even
12078 if unlink succeeds and sets $?. Needed with Solaris 8's perl 5.00503.
12080 2004-08-09 Paul Eggert <eggert@cs.ucla.edu>
12082 * tests/torture.at (Deep Package): Use configure.in, not configure.ac,
12083 for compatibility with Automake 1.4. Reported by J C Fitzgerald in
12084 <http://lists.gnu.org/archive/html/bug-autoconf/2003-08/msg00051.html>.
12086 2004-08-04 Alexandre Duret-Lutz <adl@gnu.org>
12088 * lib/autoconf/general.m4 (AC_REQUIRE_AUX_FILE): New empty macro.
12089 (AC_CANONICAL_BUILD): Call it to require config.sub and config.guess.
12090 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Likewise for install-sh.
12091 * doc/autoconf.texi (Input): Document AC_REQUIRE_AUX_FILE.
12092 * lib/autom4te.in (Automake-preselections): Preselect
12093 AC_REQUIRE_AUX_FILE. Automake 1.10 will trace it.
12095 2004-08-02 Alexandre Duret-Lutz <adl@gnu.org>
12097 * lib/autom4te.in (Automake-preselections): Preselect
12098 AC_CANONICAL_BUILD and AC_CANONICAL_TARGET. Automake 1.9.1 will
12101 2004-07-29 Paul Eggert <eggert@cs.ucla.edu>
12103 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): Set BIN_SH, for
12105 * doc/autoconf.texi (Shellology): Mention BIN_SH.
12106 Document problem with "`""`" in pdksh POSIX mode.
12108 2004-07-27 Paul Eggert <eggert@cs.ucla.edu>
12110 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): Use "set -o posix"
12111 with pdksh, too. Problem reported by Patrick Welche via
12113 * doc/autoconf.texi (Shellology): Note that set -o posix is
12114 useful for pkdsh, too.
12116 2004-06-24 Paul Eggert <eggert@cs.ucla.edu>
12118 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Require
12119 _AS_UNSET_PREPARE, so that we can use $as_unset directly.
12120 Don't fail if ENV or BASH_ENV is readonly.
12121 (AS_SHELL_SANITIZE): Don't fail if ENV, MAIL, MAILPATH, LC_ALL,
12122 etc. are read only. Problem reported by Ludovic Courtes.
12124 2004-06-23 Noah Misch <noah@cs.caltech.edu>
12126 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): If the shell is
12127 zsh, disable GLOB_SUBST to avoid backslash handling problems.
12130 2004-06-04 Paul Eggert <eggert@cs.ucla.edu>
12132 * doc/autoconf.texi (File System Conventions): Warn about
12133 names like "aux". Problem reported by Eric Blake.
12135 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY (C)): Use division
12136 by zero instead of array size, so that we can use any arithmetic
12137 constant expression (instead of requiring an integer constant
12138 expression). This allows us to test expressions like DBL_MAX <
12139 LDBL_MAX, which didn't conform to the C standard using the old
12141 (AC_C_LONG_DOUBLE): Put back in the tests for LDBL_MAX and LDBL_EPSILON,
12142 now that we can do floating-point tests at compile time.
12144 2004-06-02 Paul Eggert <eggert@cs.ucla.edu>
12146 * lib/autoconf/c.m4 (AC_C_LONG_DOUBLE): Don't check LDBL_MAX
12147 and LDBL_EPSILON, as the resulting expression isn't an
12148 integer constant expression and violates the C standard.
12149 Problem reported by Nelson H. F. Beebe. Also, check
12150 for "L" suffix, and check that long double doesn't have
12151 worse range or precision than double, that mixed-mode
12152 arithmetic doesn't generate a diagnostic, that double
12153 constants fit in long double.
12155 2004-06-03 Kevin Ryde <user42@zip.com.au>
12157 * doc/autoconf.texi (Function Portability): Add notes on free(NULL),
12158 malloc(0) and realloc(NULL,size).
12160 * doc/autoconf.texi (Shell Substitutions): Spelling error reported by
12163 2004-05-31 Paul Eggert <eggert@cs.ucla.edu>
12165 * lib/autoconf/headers.m4 (HAVE_STDBOOL_H): Detect _Bool bug
12166 in HP aC++/ANSI C B3910B A.05.55 [Dec 04 2003]. Problem reported
12169 2004-05-26 Paul Eggert <eggert@cs.ucla.edu>
12171 * doc/autoconf.texi (Limitations of Builtins): Mention that ! COMMAND
12172 can be rewritten using if-then-else. Suggested by Bruno Haible.
12174 2004-05-25 Paul Eggert <eggert@cs.ucla.edu>
12176 * doc/autoconf.texi (testsuite Scripts): Fix typo.
12177 Problem reported by Stepan Kasal.
12179 2004-05-24 Paul Eggert <eggert@cs.ucla.edu>
12181 * tests/Makefile.am (autoconfdir): Fix to match comment (trivial
12182 change). Patch reported by Ralf Wildenhues in
12183 <http://mail.gnu.org/archive/html/bug-autoconf/2004-05/msg00092.html>.
12185 * lib/autoconf/functions.m4 (AC_FUNC_MBRTOWC): Don't assume that a
12186 function F exists if the compiler and linker let you compile an
12187 expression like (F != 0). Recent versions of GCC optimize away
12188 the reference to F in that case, since every function address must
12189 be nonzero, so the link succeeds even if F does not exist.
12190 Problem reported by Manu in
12191 <http://mail.gnu.org/archive/html/bug-gnu-utils/2004-05/msg00060.html>.
12193 * doc/autoconf.texi (Systemology): Standardize on the spelling of
12194 "Unix". Many uses changed.
12195 (Limitations of Builtins): Explain better why the ! command isn't
12198 2004-05-22 Alexandre Duret-Lutz <adl@gnu.org>
12200 * lib/autom4te.in (Automake-preselections): Preselect
12201 LT_SUPPORTED_TAG in lieu of AC_LIBTOOL_TAGS.
12203 2004-05-19 Kevin Ryde <user42@zip.com.au>
12205 * doc/autoconf.texi (Function Portability): Add strerror_r, cross
12206 referencing AC_FUNC_STRERROR_R.
12208 * doc/autoconf.texi (Particular Functions): In AC_FUNC_CLOSEDIR_VOID,
12209 note pessimistic assumption when cross compiling.
12211 2004-05-16 Paul Eggert <eggert@cs.ucla.edu>
12213 * doc/autoconf.texi (Limitations of Make): Note that BSD make
12214 (until 2004) invoked subcommands with sh -e, contra POSIX.
12215 Reported by Kevin Ryde.
12217 2004-05-10 Eric Sunshine <sunshine@sunshineco.com>
12219 * programs.m4 (_AC_PROG_GREP): Fixed bug where PATH argument handed to
12220 _AC_PATH_PROG_FEATURE_CHECK contained leading whitespace (i.e.
12221 " $PATH:/usr/xpg4/bin"). This resulted in bogus tests, such as
12222 `test -f " /usr/bin/grep"', which _always_ failed.
12223 (AC_PROG_SED): Ditto bogus PATH fix.
12224 * autoconf.texi (AC_PROG_GREP): Properly document that this macro
12225 requires that grep correctly supports _multiple_ `-e' options, rather
12226 than stating only that grep should accept `-e'.
12228 2004-05-03 Paul Eggert <eggert@cs.ucla.edu>
12230 Port to C99, which requires that 'exit' be declared.
12232 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Use AC_INCLUDES_DEFAULT
12233 to ensure that stdlib.h is included.
12234 * lib/autoconf/functions.m4 (_AC_LIBOBJ_ALLOCA, AC_FUNC_SETPGRP,
12235 AC_FUNC_STRTOD, AC_FUNC_SETVBUF_REVERSED, AC_FUNC_FORK, _AC_FUNC_FORK,
12236 _AC_FUNC_VFORK, AC_FUNC_WAIT3): Likewise.
12237 * lib/autoconf/specific.m4 (AC_SYS_RESTARTABLE_SYSCALLS): Likewise.
12238 * lib/autoconf/types.m4 (AC_TYPE_GETGROUPS): Likewise.
12239 * lib/autoconf/headers.m4 (AC_HEADER_STDC): Include <stdlib.h>
12240 when using 'exit' in a test; C99 requires that 'exit' be declared.
12242 2004-05-02 Paul Eggert <eggert@cs.ucla.edu>
12244 * doc/autoconf.texi (Particular Programs): AC_PROG_GREP
12245 now prefers 'grep' implementations that accept -e.
12246 (Limitations of Usual Tools): Describe problems of traditional
12247 egrep and fgrep with long input lines, and of traditional grep
12249 * lib/autoconf/programs.m4 (AC_PROG_GREP): Check for -e, too.
12250 (_AC_PROG_GREP): Assume 3rd arg is properly quoted for the shell.
12251 All callers changed. Append /usr/xpg4/bin to the PATH, for
12253 (_AC_FEATURE_CHECK_LENGTH): Discard stderr, so we don't bother
12254 the user with complaints about multiple -e options.
12255 * tests/local.at (AC_STATE_SAVE): Use $GREP, not grep.
12256 Define it with AC_PROG_GREP.
12257 * configure.ac (AC_PROG_GREP): Add.
12258 * lib/freeze.mk (GREP): New macro.
12260 2004-05-02 Eric Sunshine <sunshine@sunshineco.com>
12262 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Consult $SHELL as
12263 a possible candidate only after all others fail, rather than
12264 consulting it first. This improves backward compatibility by
12265 better reflecting the way shell selection occurred in previous
12266 versions of Autoconf, and should help to avoid triggering latent
12267 problems in other packages, such as the one in Automake where zsh
12268 is not handled robustly:
12269 http://mail.gnu.org/archive/html/automake/2004-04/msg00095.html
12270 Although it is not Autoconf's responsibility to work around
12271 problems in Automake, it nevertheless makes sense to avoid
12272 introducing unnecessary incompatibilites.
12274 2004-04-22 Albert Chin-A-Young <china@thewrittenword.com>,
12275 Gary V. Vaughan <gary@gnu.org>
12277 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Don't guess
12278 how deeply nested we are when a suitable tool is found, set the
12279 ac_path_TOOL_found flag.
12280 (_AC_PATH_PROG_FEATURE_CHECK): Encapsulate knowledge of how deeply
12281 nested we are in this macro. Break out of all 3 nested loops if
12282 ac_path_TOOL_found is set.
12284 2004-04-21 Gary V. Vaughan <gary@gnu.org>
12286 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Break out
12287 of the _AS_PATH_WALK loop too if GNU flavor is found.
12289 2004-04-21 Alexandre Duret-Lutz <adl@gnu.org>
12291 * doc/autoconf.texi (Limitations of Make): Update documentation
12292 for `$<'. New entry `Long lines', based on a report from Simon
12293 Josefsson. Augment the documentation for SHELL = @SHELL@ with a
12294 paragraph about DJGPP, based on a mail from Richard Dawe.
12296 2004-04-20 Paul Eggert <eggert@twinsun.com>
12298 * tests/c.at (C keywords): Don't assume that GCC supports
12299 "restrict" and "inline", as sufficiently-old GCC versions do not
12300 (also, GCC configured to be in pedantic C89 mode does not).
12301 Problem reported by Sumit Pandya in:
12302 http://mail.gnu.org/archive/html/autoconf/2004-04/msg00092.html
12304 * lib/autoconf/c.m4 (_AC_PROG_CC_G, _AC_PROG_CXX_G): Don't
12305 consider -g to work if it generates warnings when plain compiles
12306 don't. Problem reported by Braden McDaniel in:
12307 http://mail.gnu.org/archive/html/autoconf-patches/2003-07/msg00014.html
12309 * doc/autoconf.texi (Slashes): New section, to document a problem
12310 reported by Jim Meyering in:
12311 http://mail.gnu.org/archive/html/bug-coreutils/2004-02/msg00060.html
12313 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Remove potential

12320 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Make the
12321 best tool so far counter rely on the tool path variable name to
12322 avoid checks for one tool being affected by the results of running
12323 the length check on a previous tool.
12325 * lib/autoconf/programs.m4 (_AC_PROG_GREP): Take an additional
12326 match expression argument, as different greps have different
12327 regular expression flavours.

12356 2004-03-28 Paul Eggert <eggert@twinsun.com>
12358 * doc/autoconf.texi (Particular Structures): AC_STRUCT_TIMEZONE
12359 now defines HAVE_DECL_TZNAME if it is declared, when
12360 HAVE_STRUCT_TM_TM_ZONE is not defined.
12361 * lib/autoconf/types.m4 (AC_STRUCT_TIMEZONE): Implement this.
12362 Do not assume atoi. Rely on HAVE_DECL_TZNAME when testing

12409 behavioral changes.
12410 * tests/mktests.sh: Do not generate tests for the
12412 * NEWS: Document these changes.
12414 * doc/autoconf.texi: Avoid macros with unbraced arguments,

12431 * bin/Makefile.am (edit): Don't use $< in a context where
12432 POSIX doesn't require support for it. Use $@.in instead.
12433 Problem reported by Anthony N. Frasso in
12434 <http://mail.gnu.org/archive/html/autoconf/2004-03/msg00008.html>.
12435 * bin/autoscan.in, bin/autoupdate.in: Add @configure_input@ comment.

12440 from the next generation of Libtool.
12441 * lib/autom4te.in (Autoreconf-preselections): Ditto.
12443 2004-02-20 Alexandre Duret-Lutz <adl@gnu.org>
12445 * doc/autoconf.texi (Limitations of Usual Tools) <mkdir>: `mkdir -p'
12446 is not always thread-safe. Report from Nathanael Nerode.

12450 Fix a dependencies problem, stemming from a Autoconf 2.59 build
12451 problem on QNX reported by Stephen Rasku in
12452 <http://mail.gnu.org/archive/html/bug-autoconf/2004-02/msg00066.html>.
12454 * bin/Makefile.am ($(srcdir)/autoconf.in): Depend on
12455 $(m4sh_m4f_dependencies); this removes a FIXME.
12456 * tests/Makefile.am ($(srcdir)/wrapper.in): Likewise.
12457 (MAINTAINERCLEANFILES): Split into pieces,
12458 one per related section. Add $(srcdir)/wrapper.in.
12460 2004-02-09 Paul Eggert <eggert@twinsun.com>
12462 * doc/autoconf.texi (Setting Output Variables): Emphasize that
12463 AC_SUBST provides no portable way to escape literal newlines.
12465 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS): Ignore all
12466 flags of the form -lcrt*.o, not just -lcrt[01].o and -lcrtbegin.o.
12467 Darwin uses -lcrt2.o and there's little point to cataloging all
12468 the system variants. Partial fix reported by Andreas Waechter in:
12469 http://mail.gnu.org/archive/html/autoconf-patches/2004-02/msg00006.html

12485 the behavior of the third argument.
12486 * lib/autoconf/autoupdate.m4 (AU_DEFUN): Describe more
12487 correctly the behavior of the third argument. Document
12488 what the three macros that AU_DEFUN defines do. Fix
12489 warning message when the third argument includes $0

12493 Eric Sunshine <sunshine@sunshineco.com>
12494 Paul Eggert <eggert@twinsun.com>
12496 * lib/m4sugar/m4sh.m4 (M4SH-SANITIZE): New diversion.
12497 (AS_INIT): Output shell initialization there. Removed optional
12498 parameter. Expand _AS_SHELL_FN_SPY.

12507 (_AS_RUN): Move it here, support testing with eval.
12508 (AS_REQUIRE_SHELL_FN): Require shell functions when
12510 (_AS_LINENO_WORKS): Put around braces, we do not
12511 trigger the bash bug anymore.
12512 * lib/autotest/general.m4: Document M4SH-SANITIZE, do not
12513 use AS_INIT_WITH_SHELL_FN.
12514 * bin/autoconf.in, tests/wrapper.in: Regenerated.
12516 2004-01-30 Paolo Bonzini <bonzini@gnu.org>

12522 (AU_DEFUN): Honor the third parameter, create autoupdate
12523 macros with AU_DEFINE.
12524 * lib/autoconf/headers.m4 (AC_USG, AC_MEMORY_H,
12525 AC_DIR_HEADER): Use AU_DEFUN's third parameter.

12544 * lib/autoconf/general.m4 (_AC_INIT_COPYRIGHT): Add 1992 thorugh

12546 the 2003-05-22 change, which removed the older years from the list.
12547 * lib/autoconf/status.m4 (AC_OUTPUT): Update copyright date to 2004.

12558 egrep and fgrep respectively if $GREP -E/-F don't work.
12559 (_AC_PATH_PROG_FEATURE_CHECK): Factor out the common core of
12560 _AC_PROG_GREP, and AC_PROG_SED.
12561 (_AC_FEATURE_CHECK_LENGTH): New helper macro for finding the
12562 longest input length accepted by a command.

12591 2004-01-26 Paul Eggert <eggert@twinsun.com>
12593 * doc/autoconf.texi (Default Includes): Include <stdint.h> even if
12594 HAVE_INTTYPES_H is defined. This is needed on Tru64 5.1b with
12595 Compac C V6.5-207 (dtk), which defines uintmax_t in <stdint.h> but
12596 not <inttypes.h>. Problem reported by Tim Mooney in
12597 <http://mail.gnu.org/archive/html/bug-coreutils/2004-01/msg00147.html>.
12598 * lib/autoconf/headers.m4 (_AC_INCLUDES_DEFAULT_REQUIREMENTS):
12601 * lib/autoconf/programs.m4 (AC_PROG_SED): Use diff, not sed;
12602 otherwise "make check" fails because it forbids cmp (I guess
12603 because cmp treats files as binary on DOS-like systems).
12605 * tests/mktests.sh: Update copyright date to 2004, since some tests
12606 have changed in 2004.
12608 2004-01-23 Gary V. Vaughan <gary@gnu.org>
12610 * lib/autoconf/programs.m4 (AC_PROG_SED): New macro to test for a
12611 non-truncating sed or gsed program in PATH.
12612 * tests/acprograms.at: Add it.
12613 * doc/autoconf.texi (Particular Programs): Document it.
12616 2004-01-15 Paul Eggert <eggert@twinsun.com>
12618 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Try -std, not -std1, since
12619 -std1 disables some useful extensions on Tru64. Problem reported
12620 by N. Lichtmaier in
12621 <http://mail.gnu.org/archive/html/autoconf/2004-01/msg00100.html>.
12623 2004-01-14 Paul Eggert <eggert@twinsun.com>
12625 * doc/autoconf.texi (Programming in M4sh): Document that
12626 AS_MKDIR_P succeeds if the destination is a symbolic link
12627 to an existing directory.
12628 (Limitations of Usual Tools): Note that mkdir -p might not
12629 succeed on symlinks to directories.
12631 2004-01-13 Paul Hilfinger <hilfinger@CS.Berkeley.EDU>
12633 * lib/autoconf/autoupdate.m4 (AU_DEFUN): Grammar fix in comment.
12634 * bin/autoheader.in: Grammar fix in message.
12635 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P):
12636 Test for dir before calling mkdir -p. (trivial changes)
12638 2004-01-13 Eric Blake <ebb9@byu.net>

12643 2004-01-10 Jim Meyering <jim@meyering.net>
12645 * doc/autoconf.texi (Running the Preprocessor): Correct grammar.
12647 2004-01-09 Paul Eggert <eggert@twinsun.com>
12649 * lib/autoconf/general.m4: Fix bug: AC_CHECK_SIZEOF evokes a warning
12650 with `autoconf -Wall,error'. Bug reported by Eric Blake in:
12651 http://mail.gnu.org/archive/html/autoconf-patches/2004-01/msg00000.html
12652 (_AC_COMPUTE_INT_COMPILE): Invoke _AC_COMPILE_IFELSE, not
12653 AC_COMPILE_IFELSE, since we now assume our caller invokes
12654 AC_LANG_COMPILER_REQUIRE, for symmetry with _AC_COMPUTE_INT_RUN.
12655 (_AC_COMPUTE_INT_RUN): Likewise, for _AC_RUN_IFELSE instead
12656 of AC_RUN_IFELSE; this avoids the warning mentioned above.
12657 (_AC_COMPUTE_INT): Invoke AC_LANG_COMPILER_REQUIRE.
12659 2004-01-07 Paul Eggert <eggert@twinsun.com>
12661 * lib/autoconf/general.m4 (_AC_LIBOBJS_NORMALIZE): Avoid \$ inside
12662 `"'...'"`, as it's confusing (and I suspect it may not work on
12663 some platforms). The code was incorrect anyway, as it assumed
12664 that \$ evaluated to itself in that context. Reported by
12665 Alexandre Duret-Lutz.
12667 2004-01-07 Alexandre Duret-Lutz <adl@gnu.org>
12669 * lib/autom4te.in (Automake-preselections): Preselect AC_LIBTOOL_TAGS
12670 and _LT_AC_TAGCONFIG.

12695 2004-01-04 Paul Eggert <eggert@twinsun.com>
12697 * lib/autoconf/general.m4 (AC_ARG_PROGRAM):
12698 Use "rm -f" to remove conftest.sed, not plain "rm".
12699 Bug reported by David Relson in
12700 <http://mail.gnu.org/archive/html/autoconf/2004-01/msg00011.html>.
12702 * Makefile.am (autom4te-update):
12703 Replace "rm -rf" and "rm -fr" with "rm -f -r", as POSIX requires.

12719 * doc/autoconf.texi (Limitations of Usual Tools): Mention that cc
12720 -c -o might not work. From a suggestion by Kevin Ryde.
12721 (C Compiler, Generating Sources, Limitations
12722 of Usual Tools, Limitations of Make, Making testsuite Scripts):
12723 Don't put '-o' after non-options, as POSIX doesn't allow this.
12724 Mention that cc's name might be gcc or c89 or whatever.
12726 2004-01-04 Kevin Ryde <user42@zip.com.au>
12728 * doc/autoconf.texi: Add various further index entries.
12730 2003-12-29 Paul Eggert <eggert@twinsun.com>
12732 * bin/autoreconf.in (autoreconf_current_directory):
12733 Fix typo: mkdir without umask arg.
12735 2003-12-27 Alexandre Duret-Lutz <adl@gnu.org>
12737 * doc/autoconf.texi (Limitations of Make) <Automatic rule rewriting>:
12738 Documents OSF1/Tru64 make behavior. Replace `VPATH = ../src' by
12739 `VPATH = ../pkg/src' in examples to make the OSF1/Tru64 make
12740 explanation clearer.
12742 2003-12-24 Andreas Schwab <schwab@suse.de>

13025 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Omit quoted

13051 cache variable instead of $G77 to decide whether to include -O2,

13062 arguments so that it can be used with syntax identical to

13064 remove/deprecate the DIALECT optional argument in the future if it
13065 proves troublesome.
13066 (AC_FC_FREEFORM): Exit 77 upon failure to fix test suite for

13138 * lib/autoconf/status.m4 (_AC_OUTPUT_COMMANDS): Make sure the
13139 directory for AC_CONFIG_COMMANDS' first argument exists.
13140 This makes valid the invocation of _AC_SRCPATH that follows.
13141 Reported by Eric Sunshine.

13165 The test suite are sometimes assigning timings incorrectly.
13166 Reported by Henk Krus.
13167 Diagnosed by Nicolas Joly.
13169 * lib/autotest/general.m4 (AT_CLEANUP): Rename AT_help as
13171 Instead of making AT_help a sequence of assignments to grow

13173 $at_help_all, and make a single assignment in...
13175 (at_times_skip): Flip the meaning and rename as...
13176 (at_times_p): this.

13187 (ifnames): chmod -w.
13188 * tests/wrapper.as (AUTOCONF, AUTOM4TE, ): Point to tests/
13189 executables, not bin/ executables! Otherwise all the magic needed
13190 to find non installed files is turned off. This caused a failure
13191 of test 40 and 41 that ran aclocal 1.8 which in turn ran autom4te
13192 as found in its environment (sent by tests/autoreconf): pointing
13193 to bin/autom4te that could not find its files.
13194 * tests/mktests.sh: Force the replacement of generated files, for
13195 the sake of "mv" program that are interactive when overwriting a

13424 2003-08-21 Akim Demaille <akim@epita.fr>
13426 First stab at preserving warnings between calls to autom4te,
13427 including when the cache is used.
13429 There are still several issues: (i) there are too many runs of m4
13430 (one for include, one for warnings, and some more), (ii) warnings
13431 spreading on several lines are not handled gracefully, (iii) the
13432 code meant to have the call stack display for errors does not work
13433 (its handling should move from m4 to autom4te).
13435 * bin/autom4te.in Autom4te::Channels, Autom4te::ChannelDefs):
13437 (@preselect): Add m4_warn.
13438 ($exit_status): Remove, use $exit_code.
13439 ($help): Use Autom4te::ChannelDefs::usage.
13440 (&handle_m4): No longer define the m4_warnings.
13441 At each run, extract and report the warnings.
13442 Always cache the result, including if the exit status is on
13443 failure, since if nothing changes, we should result in the same
13444 failure, hence we can use the cache.
13445 * lib/m4sugar/m4sugar.m4 (m4_warning_ifelse, _m4_warning_ifelse)
13446 (_m4_warning_error_ifelse, __m4_warning_error_ifelse, _m4_warn):
13448 (m4_warn): Redefine as a do-nothing: it is its invocation that
13449 matters, as warnings are now reported via traces.
13450 * lib/autoconf/general.m4 (AC_DIAGNOSE): Don't make it a copy of
13451 the contents of m4_warn: make it _call_ m4_warn, so that tracing
13452 the latter reveals calls to the former.
13456 * tests/m4sugar.at (m4@&t@_warn): Use existing warning categories.
13458 2003-08-21 Akim Demaille <akim@epita.fr>

13478 (&catfile): Remove.
13479 * bin/autoheader.in, bin/autoreconf.in, bin/autoupdate.in,
13480 * bin/autoscan.in: Adjust.
13482 2003-08-20 Akim Demaille <akim@epita.fr>
13484 * bin/autoheader.in: Remove duplicate 'use Autom4te::FileUtils'.
13485 Reported by Alexandre Duret-Lutz.
13487 2003-08-20 Akim Demaille <akim@epita.fr>
13489 * bin/autoupdate.in, bin/autoheader.in, bin/autoreconf.in,
13490 * bin/autom4te: Adjust.
13491 In particular, be Autoconf tools are really silent when properly
13492 working, bind the verbosity of the 'note' channel to $verbose.
13493 * lib/Autom4te/General.pm (&find_file, &mtime, &update_file)
13494 (&xsystem, &contents): Remove, since they are exported by...
13495 * lib/Autom4te/FileUtils.pm: this.

13621 Don't mix the detailed output of failed test with the summary of

13728 exit 63, so that we (or Automake's "missing") can tell the
13729 difference with a plain failure.
13730 * doc/autoconf.texi (Notices): Adjust.
13732 2003-05-23 Akim Demaille <akim@epita.fr>
13734 * Makefile.am, bin/Makefile.am, config/Makefile.am,
13735 * doc/Makefile.am, lib/autoconf/Makefile.am, tests/Makefile.am:

13739 Paul Eggert <eggert@twinsun.com>
13741 * lib/autoconf/c.m4 (_AC_PROG_CXX_EXIT_DECLARATION):
13742 Remove `#include <stdlib.h>' from the list; we should never
13743 make confdefs.h include <stdlib.h> or <cstdlib>, because the
13744 resulting namespace pollution would cause other tests to fail.
13745 Configure scripts run with some older versions of g++ and HP's
13746 aCC would fail due to such an #include. Problems reported by
13747 Matthew Mueller in <http://bugs.debian.org/120704> and by
13749 <http://mail.gnu.org/archive/html/autoconf/2003-05/msg00063.html>.
13750 In the test, use the test declaration before including <stdlib.h>,
13751 as that's closer to how it'll be used.
13753 2003-05-23 Akim Demaille <akim@epita.fr>
13755 * doc/autoconf.texi (Header Portability): ucred.h.
13758 2003-05-22 Paolo Bonzini <bonzini@gnu.org>
13760 Overhaul Autotest's logging: generate separate log files
13761 in testsuite.dir/NNN/testsuite.log, and append them to
13762 testsuite.log instead of re-running the test verbosely.
13764 * lib/autotest/general.m4 (AT_INIT): Use a single redirected
13765 file descriptor, write 0 to at_status_file instead of setting
13766 at_status=0, initialize some new variables (at_status_file,
13767 at_group_log, at_suite_log, at_tee_pipe). Remove the cruft
13768 to rerun the tests, instead append the at_group_log to the
13769 at_suite_log when a test fails.
13770 (AT_SETUP): pipe the test case's output into at_tee_pipe,
13771 with the AS_MESSAGE_LOG_FD redirected to stdout.
13772 (AT_CLEANUP): save the output status in $at_status_file
13773 and restore it, redirect the AS_MESSAGE_LOG_FD back to
13774 its original place.
13775 (AT_CHECK): since tests are run with a redirected stdout,
13776 and used to be re-run in verbose mode, turn some $at_verbose
13777 into echo, and don't redirect the output of testing stdout
13780 * lib/autotest/autoconf.texi (testsuite Scripts): Update
13781 the name of the debugging directory and information about

13901 2003-05-06 Akim Demaille <akim@epita.fr>
13903 Don't try to be smart with aclocal 1.8+ because (i) aclocal no
13904 longer updates aclocal.m4 if useless, (ii) if a file m4_included
13905 by aclocal.m4 is changed it might require the importing of another
13906 m4 extension file, i.e., aclocal must be run.
13908 * bin/autoreconf.in (&run_aclocal, $aclocal_supports_force): New.
13909 (&parse_args): Use --force with aclocal if required and supported.

13923 2003-04-29 Derek Price <derek@ximbiot.com>
13925 * lib/autotest/general.m4 (AT_KEYWORDS): Don't use a comma as the
13926 seperator with m4_append_uniq(). It doesn't work.
13927 (AT_CLEANUP): Add `;' to end of at_help_all.
13928 (AT_INIT): Allow --keywords to be specified more than once. When
13929 grepping $at_help_all for keywords, use the field and keyword
13930 seperators to ensure a complete keyword match. Alter at_prev handling
13931 to support the new --keywords behavior.
13933 2003-04-27 Karl Berry <karl@freefriends.org>
13935 * doc/autoconf.texi: Make the dir entries in the autoconf manual
13936 align better with others. I also made some of the individual
13937 entries on one line, for brevity and to make it easier for me to
13938 sort my dir-example file in the Texinfo distribution :).

14005 header causes problems.
14007 2003-03-28 Akim Demaille <akim@epita.fr>
14009 * tests/torture.at (Configuring subdirectories): Require aclocal
14010 1.4, otherwise the test fails, as it does support configure.ac.

14084 (Automake): Automake 1.5+ no longer requires special tools to be
14085 present on the developer's host.

14131 format starting with "-".
14133 2003-02-20 Alexandre Duret-Lutz <adl@gnu.org>

14136 is not portable inside Makefile.
14138 2003-02-20 Akim Demaille <akim@epita.fr>
14140 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): When
14141 compiler says yeah, but preproc says nope, compiler is right.
14142 Conversely, prompt the reader to send a bug report to the
14143 maintainers of the package, not of Autoconf.
14145 2003-02-20 Klee Dienes <kdienes@apple.com>

14158 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Define $1 to an
14159 innocuous variant befor including <limits.h> or <assert.h>. This
14160 works around a bug reported by Albert Chin: HP-UX 11i
14161 (and earlier versions) have a <limits.h> that declares
14162 gettimeofday and many other functions.
14164 2002-12-03 Paul Eggert <eggert@twinsun.com>
14168 * NEWS, configure.ac: Update version.

14172 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Use the function f
14173 nontrivially in main's body, so that f's external declaration is
14174 not optimized away in AIX. This should fix the bug reported by
14176 <http://mail.gnu.org/pipermail/autoconf/2002-November/014508.html>.
14178 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C),
14179 _AC_PROG_PREPROC_WORKS_IFELSE): Use <limits.h> if __STDC__ is
14180 defined, to support freestanding compilers. This should fix the
14181 bug reported by Momchil Velkov in
14182 <http://mail.gnu.org/pipermail/autoconf/2002-November/014490.html>.
14184 * doc/autoconf.texi (Obsolete Macros): Fix typos (insert empty
14185 arg, AC_DEFINE -> AC_DEFINE_UNQUOTED) in documentation for
14186 obsolete AC_CHECK_TYPE. The missing empty arg was reported
14187 by Simon Josefsson in
14188 <http://mail.gnu.org/pipermail/autoconf-patches/2002-December/008830.html>.
14190 * Makefile.maint (www-gnu): New macro.
14191 (standards.texi-url_prefix, make-stds.texi-url_prefix): Use it, as
14192 the location has moved.
14194 2002-12-02 Martin Frydl <martin@systinet.com>
14196 * bin/autom4te.in (at_flatten): rewritten to avoid M4 problem when
14197 \(.*\) match is too long and there is something more to be checked.
14198 <http://mail.gnu.org/pipermail/autoconf/2002-November/014524.html>

14216 Update from masters.
14218 2002-11-14 Akim Demaille <akim@epita.fr>
14220 * Makefile.maint: Sync with Bison, i.e.:
14221 (po-check): Scan .l and .y files instead of the
14222 .c and the .h files that they generate. This fixes the bug
14223 reported by Tim Van Holder in:
14224 <http://mail.gnu.org/pipermail/bison-patches/2002-November/001352.html>
14225 Look for N_ as well as for _. Try to avoid matching #define for

14241 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Initialize f=$1 rather
14242 than assigning in main, to avoid HP cc +O3 optimizing it away.

14246 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Add -q
14247 option. Process --recheck after parsing all options. Pass -q
14248 option to configure on --recheck.
14249 (AC_OUTPUT): Pass -q from configure to config.status.

14280 Reported by Ezra Peisach.
14282 2002-11-05 Akim Demaille <akim@epita.fr>
14284 * lib/autoconf/autoheader.m4 (_AH_TEMPLATE_OLD, _AH_VERBATIM_OLD):
14286 We _have_ to stop using the old compatibility scheme that tried to
14287 avoid useless backslashes because Libtool 1.4.3 contains a
14288 AC_DEFINE([error_t], [int],
14289 [Define to a type to use for \`error_t' if it is not
14290 otherwise available.])
14291 We _have_ to quote the single quote and backslashes with \. The
14292 old compatibility scheme saw that ` was backslashed, and therefore
14293 did not quote the single quote. Hence before this patch, Autoconf
14294 was not compatible with Libtool.

14298 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Set the following variables,

14318 * doc/autoconf.texi (autoreconf Invocation): Adjust.

14339 `$(MAKE)' instead of '${MAKE}' to emphasize that we refer to the
14340 Make variable, not a shell variable.
14341 Suggested by Bruno Haible.
14343 2002-10-31 Akim Demaille <akim@epita.fr>
14345 * bin/autom4te.in (load_configuration): Reject #args out of any

14367 AC_FUNC_REALLOC check for compatibility with glibc, not POSIX.
14368 Problem reported by Bruno Haible.
14370 2002-10-29 Akim Demaille <akim@epita.fr>
14372 * doc/autoconf.texi (Header Templates): Put also in words what the

14685 Reported by Alexandre Duret-Lutz.
14687 * bin/autom4te.in (&parse_args): Do not prepend `--reload-state'

14708 if some file was changed instead of `print'.
14709 * bin/autoheader.in: Suggest AC_DEFINE with 3 args when needed.
14710 (&parse_args): Remove the dead options.
14711 * tests/atspecific.m4 (AT_CHECK_AUTOHEADER): Adjust to the new
14712 autoheader's quiet mode.
14713 (AT_CHECK_AUTOUPDATE): Likewise.
14714 * tests/tools.at (autoupdate): Adjust.
14715 * tests/semantics.at (AC_C_BIGENDIAN): Likewise.
14717 2002-10-11 Akim Demaille <akim@epita.fr>
14719 No longer use CPP to check for the existing of headers: use CC to
14720 check for compilability.
14722 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL)
14723 (AC_CHECK_HEADER, _AC_CHECK_HEADER_OLD): Remove.
14724 (_AC_CHECK_HEADER_NEW): Rename as...
14725 (AC_CHECK_HEADER): this.
14727 * lib/autotest/general.m4 (AT_INIT): Include the failed test
14728 numbers in the Subject suggestion.
14730 2002-10-11 Akim Demaille <akim@epita.fr>
14732 * lib/autoconf/specific.m4 (AC_DECL_SYS_SIGLIST): Obsolete.
14733 Suggest using AC_CHECK_DECLS instead.
14735 2002-10-11 Akim Demaille <akim@epita.fr>
14737 * tests/torture.at (AC_ARG_VAR): Have configure report the value
14740 2002-10-11 Akim Demaille <akim@epita.fr>
14742 * lib/m4sugar/m4sh.m4 (_AS_PATH_SEPARATOR_PREPARE): Use $$ in the
14743 file name to enable parallel executions.
14744 From Sam Varshavchik.
14746 2002-10-08 Akim Demaille <akim@epita.fr>
14748 * bin/autoreconf.in (&autoreconf): Run autopoint before the first
14749 aclocal invocation, as Gettext macros might not be visible to
14751 Instead of blindly running autopoint, scan configure.ac (not the
14752 traces) for AM_GNU_GETTEXT_VERSION uses, as autopoint does.
14753 Reported by Paul D. Smith.
14755 2002-10-08 Paul Eggert <eggert@twinsun.com>
14757 Work around problems found when POSIXLY_CORRECT=1 is set.
14758 None of this seems to have anything to do with POSIX, really,
14759 but it's how Perl getopt works.
14760 * bin/autom4te.in (parse_args): Configure GetOpt with
14762 * doc/autoconf.texi (Invoking autom4te):
14763 --warning -> --warnings.
14764 * lib/autom4te.in: --warning -> --warnings.
14766 2002-09-28 Akim Demaille <akim@epita.fr>
14768 * doc/autoconf.texi (autom4te.cache): New section.
14770 2002-09-28 Akim Demaille <akim@epita.fr>
14772 * lib/autom4te.in (Autoscan-preselections, Autoreconf-preselections)
14773 (Automake-preselections): Update.

14776 2002-09-28 Akim Demaille <akim@epita.fr>
14778 * lib/autoscan/autoscan.pre: Move all the remaining rules to...
14779 * lib/autoconf/c.m4, lib/autoconf/functions.m4,
14780 * lib/autoconf/headers.m4, lib/autoconf/libs.m4,
14781 * lib/autoconf/specific.m4, lib/autoconf/types.m4: here.
14783 2002-09-28 Akim Demaille <akim@epita.fr>
14785 * tests/torture.at (Configuring subdirectories): Be robust to
14786 users who use config.site to require for a cache: in this case,
14787 the two last configure runs, using two different sets of
14788 arguments, trigger a legitimate error.
14790 2002-09-28 Akim Demaille <akim@epita.fr>
14792 * tests/m4sh.at (Functions Support, Functions and return Support):
14795 2002-09-28 Akim Demaille <akim@epita.fr>
14797 * bin/Makefile.am (ETAGS_SH, ETAGS_PERL): Update: ifnames and
14798 autoheader are Perl programs.
14799 (autoconf, autoheader, autoreconf, autoupdate, ifnames, autoscan)
14800 (autom4te): Specify that the sources are in the $srcdir.
14801 * doc/autoconf.texi (Installation Directory Variables): Adjust.

14808 * lib/autoscan/autoscan.pre (AWK, BISON, INSTALL, LEX, LN, MAKE)
14809 (RANLIB, YACC, awk, bison, byacc, flex, gawk, install, lex, ln)
14810 (make, mawk, nawk, ranlib, yacc): Similarly, move to...
14811 * lib/autoconf/programs.m4: here.

14821 that were listed in the original autoscan.list.
14822 * lib/autoconf/headers.m4: Similarly with headers.
14823 * lib/freeze.mk (autoconf_m4f_dependencies): Add autoscan.m4.
14824 (.m4.m4f): Don't pass --prepend-include, since that's done by
14825 tests/autom4te itself.
14826 * lib/autoscan/Makefile.am: Include freeze.mk.
14827 (autoscan.list): New target --this file is no longer a source.
14828 (autoscan.pre): New file.
14830 2002-09-28 Akim Demaille <akim@epita.fr>
14832 * bin/autoscan.in (@kinds): Make them singular.
14834 (&init_tables): When --debug, report the list of rules to ease
14835 tracking changes in autoscan.list.
14836 * lib/autoscan/autoscan.list (function): Strip comments, sort.
14838 2002-09-28 Akim Demaille <akim@epita.fr>
14840 * lib/autoscan/functions, lib/autoscan/headers,
14841 * lib/autoscan/identifiers, lib/autoscan/makevars,
14842 * lib/autoscan/programs: Merge into...
14843 * lib/autoscan/autoscan.list: this.
14844 * bin/autoscan.in (&init_tables): Adjust.
14846 2002-09-28 Akim Demaille <akim@epita.fr>
14848 * lib/autoscan/functions, lib/autoscan/headers,
14849 * lib/autoscan/identifiers, lib/autoscan/makevars,
14850 * lib/autoscan/programs: Make the `kind' explicit, i.e., each
14851 `functions' line is now prefixed with `function:'.
14852 * bin/autoscan.in (&init_tables): Adjust.
14854 2002-09-28 Akim Demaille <akim@epita.fr>
14856 From now on, autoscan files must always map a macro name to a
14857 word: there is no `default' macro for autoscan.
14859 * bin/autoscan.in (&init_tables): Reject entries with no macro at
14861 * lib/autoscan/functions, lib/autoscan/headers: Make the macro
14864 2002-09-28 Akim Demaille <akim@epita.fr>
14866 * bin/autoscan.in (%c_keywords): Remove.
14867 (&used): Keep only track of the words we might be interested in.
14868 (&output_kind): It is no longer needed to look for non active
14871 2002-09-27 Akim Demaille <akim@epita.fr>
14873 * lib/autoconf/functions.m4 (AC_FUNC_MBRTOWC): New, stolen from

14875 * lib/autoscan/functions: Adjust.
14876 * doc/autoconf.texi (Particular Functions): Adjust.
14878 2002-09-27 Akim Demaille <akim@epita.fr>

14882 Thanks to Bill Moseley and Paul Eggert.
14883 * lib/m4sugar/m4sh.m4 (AS_TMPDIR): $2 is the directory into which
14884 the tmpdir must be created.
14885 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Have the tmp
14886 dir be in the build tree, instead of $TMPDIR.
14888 2002-09-27 Akim Demaille <akim@epita.fr>
14890 * bin/autoscan.in: Improve the comments.
14891 (&parse_args): Drop obsolete undocumented options.
14892 (&output_kind): Output warnings.
14893 * lib/autoscan/functions: (dcgettext): Now trigger AM_GNU_GETTEXT.
14894 (getwd): Trigger a warning.
14896 2002-09-26 Akim Demaille <akim@epita.fr>
14898 * bin/autoreconf.in: Clarify that -s is meaningless without -i.
14899 Reported by Ralf Corsepius.
14900 * doc/autoconf.texi (autoreconf Invocation): Likewise.
14902 2002-09-26 Akim Demaille <akim@epita.fr>
14904 Single suffix rules and seperated dependencies are not portable.
14906 * doc/autoconf.texi (Installation Directory Variables): Update.
14907 (Limitations of Make): Some about `Single Suffix Rules and
14908 Separated Dependencies'.
14909 * bin/Makefile.am (autoconf, autoheader, autoreconf, autoupdate)
14910 (ifnames, autoscan, autom4te): Un-factor into several rules.
14912 2002-09-25 Paul Eggert <eggert@twinsun.com>
14914 * BUGS (Interoperability bugs): New section. Mention libtool
14915 1.4.2, configure.ac, and AC_CONFIG_AUX_DIR interoperability bug.
14917 2002-09-24 Paul Eggert <eggert@twinsun.com>
14919 Fix a portability bug reported by Alexandre Duret-Lutz: Solaris 8
14920 make handles suffix-rules differently from GNU make.
14922 * bin/Makefile.am (SUFFIXES, .in): Remove.
14923 (autoconf autoheader autoreconf autoupdate ifnames autoscan autom4te):
14924 Move the body of the old .in rule here.
14926 2002-09-16 Akim Demaille <akim@epita.fr>
14928 i960 compilers create `b.out' files by default.
14929 Reported by Ralf Corsepius.
14931 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT): Remove b.out files.
14932 (_AC_COMPILER_EXEEXT_DEFAULT): Adjust to b.out.
14934 2002-09-13 Paul Eggert <eggert@twinsun.com>
14936 * doc/autoconf.texi (Particular Headers): Remove obsolete
14937 reference to `struct timezone' in the description of
14940 2002-09-13 Akim Demaille <akim@epita.fr>
14944 * config/config.sub, config/config.guess: Update.
14945 * Makefile.maint: Update from bits of the Coreutils 4.5.1.
14946 * Makefile.am: Adjust.
14948 2002-09-13 Akim Demaille <akim@epita.fr>
14950 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Suggest
14951 reading config.log when the compiler is rejected.
14952 Suggested by Guido Draheim.
14954 2002-09-13 Akim Demaille <akim@epita.fr>
14956 * bin/autoreconf.in: Don't use Cwd::chdir, since in its internals
14957 (chdir_init) might hang when stat'ing mounted directories.
14958 Reported by Vance Shipley.
14960 2002-09-12 Akim Demaille <akim@epita.fr>
14962 * bin/autoscan.in (&parse_args): Pass a reference to the lists, not
14965 2002-09-12 Akim Demaille <akim@epita.fr>
14967 * doc/autoconf.texi (Defining Symbols): Present two different
14968 prototypes for AC_DEFINE and AC_DEFINE_UNQUOTED to emphasize the
14969 difference between 1 argument calls, and 2-3 argument calls.
14971 2002-09-12 Peter Eisentraut <peter_e@gmx.net>
14973 * doc/autoconf.texi: Review grammar and punctuation.
14975 2002-09-11 Paul Eggert <eggert@twinsun.com>
14977 * doc/autoconf.texi: Fix minor formatting, spelling, and
14979 (Defining Symbols): Explain that AC_DEFINE(var) defaults to 1, but
14980 AC_DEFINE(var,,description) does not; and the AC_DEFINE(var) case
14983 2002-09-11 Akim Demaille <akim@epita.fr>
14985 * doc/autoconf.texi (Questions): Rename as...
14987 (Defining Directories): New.
14989 2002-09-09 Akim Demaille <akim@epita.fr>
14991 * doc/autoconf.texi (Making testsuite Scripts): Update.
14992 Suggested by Nishio Futoshi.
14994 2002-09-09 Koji Arai <JCA02266@nifty.ne.jp>
14996 * doc/autoconf.texi (Making testsuite Scripts): Use `@@' where a
14997 plain `@' is wanted.
14999 2002-09-09 Akim Demaille <akim@epita.fr>
15001 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Keep the
15002 `duplicates', since the algorithm was too naive and could keep
15003 `--prefix=1 --prefix=2 --prefix=1' as `--prefix=1 --prefix=2', and
15004 keep `--prefix foo --prefix bar' as `--prefix foo bar'.
15005 Reported by Ralf Corsepius.
15006 * tests/torture.at (Configuring subdirectories): Exercise these
15009 2002-09-09 Akim Demaille <akim@epita.fr>
15011 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Use $srcdir when
15012 looking for a replacement file.
15013 * lib/autoconf/general.m4 (AC_CHECK_DECLS): Check that the
15014 directory is relative.
15015 * doc/autoconf.texi (Generic Functions): Clarify the replacement
15016 directory definition.
15017 Reported by Andreas Schwab and Jim Meyering.
15019 2002-09-06 Akim Demaille <akim@epita.fr>
15021 * doc/autoconf.texi (Setting Output Variables): Clarify what
15022 precious variables are.
15023 Suggested by Pontus Skoeld.
15025 2002-09-05 Akim Demaille <akim@epita.fr>
15027 * bin/Makefile.am (autoconf, autoheader, autoreconf, autoupdate)
15028 (ifnames, autoscan, autom4te): Since we don't only depend on
15029 configure.ac variables (such as VERSION etc.), but also on prefix
15030 and so forth, depend on Makefile, not configure.ac.
15031 Reported by Alexandre Duret-Lutz.
15032 * doc/autoconf.texi (Installation Directory Variables): Adjust.
15034 2002-09-05 Kevin Ryde <user42@zip.com.au>
15036 * doc/autoconf.texi (Limitations of Make): HP-UX trailing backslashes
15037 doesn't seem to be confined to ia64, just say "some versions".
15039 2002-09-04 Akim Demaille <akim@epita.fr>
15041 * Makefile.am, doc/Makefile.am: Remove pdf targets, handled by
15043 * Makefile.am (maintainer-clean-local): Remove.
15044 (MAINTAINERCLEANFILES): Remove COPYING.
15046 2002-09-03 Paul Eggert <eggert@twinsun.com>
15048 * doc/autoconf.texi (Configuration Commands): Remove obsolete
15049 example for AC_CONFIG_COMMANDS_PRE. Problem reported by Marcus
15052 2002-09-03 Akim Demaille <akim@epita.fr>
15054 * configure.ac: Bump to 2.53d.
15055 * Makefile.am (AUTOMAKE_OPTIONS): Require 1.6c, i.e., CVS Automake
15056 as of today, on Automake's team suggestion.
15058 2002-09-03 Akim Demaille <akim@epita.fr>
15062 2002-09-02 Akim Demaille <akim@epita.fr>
15064 * bin/autom4te.in (parse_args): Don't honor AUTOM4TE_PATH and
15066 * configure.ac: Disable SITE_MACRO_DIR.
15068 2002-09-02 Jim Meyering <meyering@lucent.com>
15070 * doc/autoconf.texi (AC_SYS_POSIX_TERMIOS): Reflect renaming: s/am/ac/,
15071 i.e., change am_cv_sys_posix_termios to ac_cv_sys_posix_termios.
15072 Also, tweak grammar: s/make sure to/be sure to/.
15074 2002-09-02 Paul Eggert <eggert@twinsun.com>
15076 * doc/autoconf.texi (Limitations of Builtins): Explain why logical
15077 directory names are generally preferable to physical names.
15079 2002-09-02 Akim Demaille <akim@epita.fr>
15081 * lib/Autom4te/General.pm (&update_file): s/die/error/.
15082 Reported by Raja R. Harinath.
15083 * bin/autoheader.in, bin/autoreconf.in, bin/autoscan.in,
15084 * bin/autoupdate.in: Use error instead of die.
15086 2002-09-01 Paul Eggert <eggert@twinsun.com>
15088 * tests/mktests.sh (ac_exclude_egrep, au_exclude_egrep): Use
15089 ordinary shell concatenation rather than echo+tr+sed command that
15090 runs afoul of a long-line-related sed bug in Solaris 8.
15092 * bin/autoheader.in (parse_args): --warning -> --warnings.
15094 * bin/autoconf.as: Work even if "ls" outputs "FOO not found" to
15095 stdout, as traditional "ls" does.
15096 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT,
15097 _AC_COMPILER_EXEEXT_O): Likewise.
15098 * doc/autoconf.texi (Limitations of Usual Tools): Add "ls".
15100 * bin/autoconf.as: Add --prepend-include option. This patch was
15101 applied to bin/autoconf.in in the 2002-07-17 patch by Mark D. Roth,
15102 but bin/autoconf.in is generated automatically from bin/autoconf.as.
15104 * bin/autoconf.in, configure: Regenerate.
15106 * doc/autoconf.texi (Special Shell Variables): Mention
15107 ENV, MAIL, MAILPATH, PS1, PS2, PS4. Index PWD.
15109 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Unset ENV, MAIL,
15110 MAILPATH and set PS1, PS2, PS4 to default values, to work
15111 around bug in pre-3.0 UWIN ksh reported by Bruce Lilly.
15112 For LC_ALL etc, first try to set to "C" as POSIX requires and as
15113 the Autoconf documentation specifies; fall back to "unset" only if
15114 this fails. Use a shell for-loop for this rather than an m4 loop,
15115 to shorten the output script.
15117 2002-08-30 Paul Eggert <eggert@twinsun.com>
15119 * doc/autoconf.texi (Special Shell Variables): Mention POSIX
15120 1003.1-2001's requirements for CDPATH. Give a simpler workaround
15121 for the CDPATH problem. Document PWD.
15122 (Limitations of Builtins): Document the problem that "cd $foo" and
15123 "ls $foo" may refer to different directories in shells conforming
15124 to POSIX 1003.1-2001. Use PS1 rather than CDPATH for "unset"
15125 example, since the old example is now out of date.
15127 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Reject FOO if "cd
15128 FOO" and "ls FOO" talk about different directories; this catches
15129 problems when POSIX 1003.1-2001 "cd" fails due to symlink
15132 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Use AS_UNSET instead
15133 of rolling our own unset.
15134 (_AS_PREPARE): $as_unset CDPATH instead of AS_UNSETting it, since
15135 in practice we needn't worry about CDPATH if unset doesn't work.
15137 * Makefile.in, aclocal.m4, bin/Makefile.in,
15138 config/Makefile.in, doc/Makefile.in, lib/Makefile.in,
15139 lib/Autom4te/Makefile.in, lib/autoconf/Makefile.in,
15140 lib/autoscan/Makefile.in, lib/autotest/Makefile.in,
15141 lib/emacs/Makefile.in, lib/m4sugar/Makefile.in, man/Makefile.in,
15142 tests/Makefile.in: Regenerate with Automake 1.6.3.
15144 * config/config.guess, config/config.sub, config/mkinstalldirs:
15147 * configure: Regenerate with self.
15149 2002-08-30 Kevin Ryde <user42@zip.com.au>
15151 * doc/autoconf.texi (Limitations of Usual Tools): Notes on "cc"
15154 2002-08-29 Rainer Orth <ro@TechFak.Uni-Bielefeld.DE>
15156 * bin/autom4te.in (Request::load): Correctly test for "do" read
15159 2002-08-29 Akim Demaille <akim@epita.fr>
15161 * lib/Autom4te/General.pm (&xqx): New.
15162 (&xsystem): Use WIFEXITED and WEXITSTATUS instead of decoding $? by
15163 hand, which is not portable.
15165 * bin/autom4te.in: Use them.
15166 Use &error instead of die.
15167 * tests/m4sugar.at (m4_warn, m4_require: circular dependencies):
15170 2002-08-17 Paul Eggert <eggert@twinsun.com>
15172 * lib/autoconf/fortran.m4 (AC_PROG_F77): Remove fc from the
15173 default list of compilers to try, since it was long ago superseded
15174 by the ksh fc builtin. Suggested by Steven G. Johnson.
15176 2002-07-31 Alexandre Duret-Lutz <duret_g@epita.fr>
15178 * doc/autoconf.texi (Invoking autom4te): End the option table,
15179 fixing a bug introduced by the previous patch.
15180 (Limitations of Make): Add a 'target lookup' subentry in the
15181 'VPATH' entry. Rewrite all `make' occurences as `@command{make}'.
15183 2002-07-29 Mark D. Roth <roth@feep.net>
15185 * bin/autom4te.in: Remove --include-envvar and --site-macro-subdir
15186 options and use $AUTOM4TE_PATH.
15187 * doc/autoconf.texi: Remove documentation of autom4te
15188 --include-envvar and --site-macro-subdir options and document
15189 use of $AUTOM4TE_PATH.
15190 * lib/autom4te.in: Remove --include-envvar and --site-macro-subdir
15191 arguments from each language section.
15193 2002-07-29 Paul Eggert <eggert@twinsun.com>
15195 * doc/install.texi: Include copyright symbol in copyright notice.
15197 * Makefile.am (MAKEINFO): Remove; it's a user-specified macro.

15490 This improves on an earlier suggestion by H. Peter Anvin.
15492 2002-05-16 Paul Eggert <eggert@twinsun.com>
15494 AC_FUNC_FNMATCH now tests only for POSIX compatibility.
15495 AC_FUNC_FNMATCH_GNU also tests for GNU extensions.
15496 Both macros now accept an optional source-dir arg.
15497 New macro AC_GNU_SOURCE to define _GNU_SOURCE.
15499 * NEWS: Document this.
15500 * doc/autoconf.texi (Particular Functions, UNIX Variants): Likewise.
15502 * lib/autoconf/functions.m4 (_AC_FUNC_FNMATCH): New macro.
15503 (AC_FUNC_FNMATCH): Use it. Test only for POSIX conformance,
15504 not for GNU extensions; this undoes part of the 2000-11-03 change,
15505 reverting to 2.13-compatible behavior.
15506 Add new optional argument DIR.
15507 (AC_FUNC_FNMATCH_GNU): New macro.

15513 * lib/autoconf/headers.m4 (AC_HEADER_TIOCGWINSZ):
15514 Don't require AC_SYS_POSIX_TERMIOS. The test is unnecessary,
15515 and it causes a 'test' syntax error if it fails.
15516 Bug reported by Stephen Gildea.
15518 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
15519 If prototypes are supported, use them to check this at compile-time,
15520 instead of trying to check it at run-time. If we must do a run-time
15521 check, assume that setvbuf is standard when cross-compiling, as
15522 nonstandard setvbuf occurs only on ancient and unlikely hosts.
15523 Bug reported by Paul D. Smith.
15525 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Add optional
15526 argument specifying location of getloadavg.c. This removes a
15527 FIXME. This idea was taken from Jim Meyering's implementation in
15529 * doc/autoconf.texi (Particular Functions): Document this.
15530 Also, mention HAVE_NLIST_H rather than NLIST_STRUCT, since
15531 that's what the code does; this fixes a bug reported by

15537 autopoint instead of gettextize.
15538 ($uses_alocal): Rename as...
15539 ($uses_aclocal): this.
15540 * doc/autoconf.texi (autoreconf Invocation): Adjust.
15541 Suggested by Bruno Haible.

15547 2002-04-29 Paul Eggert <eggert@twinsun.com>
15549 * bin/autoreconf.in (autoreconf): Don't age aclocal.m4's input
15550 files to be 1 second older; just set them to be the same time.
15551 Also, sleep 1 second after the first aclocal, to work around
15552 problems with sub-second time stamps on the input files.
15554 2002-04-29 Thien-Thi Nguyen <ttn@gnu.org>
15556 * doc/autoconf.texi: Mention "set -e -x" lossage

15563 From Christian Cornelssen.
15565 2002-04-29 Akim Demaille <akim@epita.fr>
15567 * tests/m4sh.at (LINENO): If testsuite itself is rewritten because
15568 of lack of $LINENO support, then the test will compare the $LINENO
15569 in testsuite vs. the lineno in the test file. This is wrong, of
15571 Be sure to protect it.
15572 Reported by Patrick Welche.
15574 2002-04-25 Akim Demaille <akim@epita.fr>
15576 * doc/autoconf.texi (Obsolete Macros): Typo.
15577 Reported by Vladimir Volovich.
15579 2002-04-25 Akim Demaille <akim@epita.fr>
15581 * bin/autoreconf.in (autoreconf): Don't let aclocal.m4 be older
15582 than some of the input files, hence, on the second run of aclocal,
15583 if some of its input are younger, make them older.
15584 Suggested by Paul Eggert.
15586 2002-04-25 Akim Demaille <akim@epita.fr>
15588 * doc/autoconf.texi (Limitations of Usual Tools): sed and `!'.

15595 AC_SUBST_FILES'ed and AC_SUBST'ed identifiers. Output them in the
15597 (_AC_INIT_PREPARE): Use them to log them.
15598 (_AC_SUBST, _AC_SUBST_SED_PROGRAM): Remove.
15599 (AC_SUBST, AC_SUBST_FILE): Instead of buliding the
15600 _AC_SUBST_SED_PROGRAM, store the list of output files/variables in
15601 _AC_SUBST_FILES and _AC_SUBST_VARS.

15604 2002-04-24 Akim Demaille <akim@epita.fr>
15606 * bin/autoreconf.in (autoreconf): Run automake after autoconf and
15607 autoheader, so that automake does not complain about a missing

15694 2002-04-19 Alexandre Duret-Lutz <duret_g@epita.fr>
15696 * bin/autoupdate.in (handle_autoconf_macros): Honor AU_DEFUNs
15697 from aclocal.m4 too.
15699 2002-04-12 Akim Demaille <akim@epita.fr>
15701 * tests/wrappl.as: New, M4sh precursor of wrappl.in.
15703 2002-04-10 Akim Demaille <akim@epita.fr>
15705 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Install the Zsh
15706 workaround for ${1+"$@"}.
15707 * doc/autoconf.texi (Shell Substitutions): Explain it.
15708 From Oliver Kiddle and Peter Stephenson.
15710 Have M4sh perform minimal shell sanitizing.
15712 * lib/m4sugar/m4sh.at (AS_SHELL_SANITIZE): Split the `_AS_PREPARE_*'
15714 (_AS_PREPARE): this new macro.
15716 (AS_INIT): Invoke AS_SHELL_SANITIZE.
15717 * tests/m4sh.at (AT_DATA_LINENO): Use _AS_PREPARE.
15719 Adjust Autoconf and Autotest.
15721 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Don't invoke
15722 AS_SHELL_SANITIZE, AS_INIT did it, but invoke AS_PREPARE.
15723 * lib/autotest/general.m4 (AT_INIT): Likewise.
15724 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
15725 Invoke _AS_PREPARE (not AS_PREPARE) in addition to
15728 Use this M4sh to generate Autoconf's shell scripts.
15730 * tests/wrapsh.as: New, precursor of wrapsh.in.
15731 * tests/Makefile.am: Include lib/freeze.mk to get the dependencies
15732 on Autotest and M4sh.
15733 ($(TESTSUITE)): Use $(autotest_m4f_dependencies).
15734 (wrapsh.in): New target.
15735 * bin/autoconf.as: New, precursor of autoconf.in.
15736 (autoconf.in): New target.
15738 2002-04-09 Alexandre Duret-Lutz <duret_g@epita.fr>

15741 with indented comments in rules.

15756 directories when descending in a SUBDIRS.
15757 Reported by Ezra Peisach.
15759 2002-04-04 Andreas Schwab <schwab@suse.de>
15761 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Only simplify if path
15762 contains no literal separators.
15764 2002-04-03 Akim Demaille <akim@epita.fr>
15766 * lib/autoconf/status.m4 (_AC_CONFIG_FILE, _AC_CONFIG_HEADER)
15767 (_AC_CONFIG_COMMAND, _AC_CONFIG_LINK): New.
15768 Use dnl, not the KILL diversion.
15770 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_COMMANDS)
15771 (AC_CONFIG_LINKS): here.
15773 Don't use the KILL diversion, as it kills spurious output, which
15774 results in failures being hidden.
15775 Use m4_defn where appropriate.
15776 (AC_CONFIG_IF_MEMBER): Kill the real bug: a spurious parenthesis
15777 after the second argument.
15779 * lib/autom4te.in (Autoconf, Autotest, M4sh): Don't pass --warning
15780 syntax, as it is provided by M4sugar.
15781 * tests/torture.at (Multiple AC_CONFIG_FILES): New.
15783 2002-04-03 Andreas Schwab <schwab@suse.de>

15798 Fixes Debian #138666.
15800 2002-04-02 Peter Eisentraut <peter_e@gmx.net>
15802 Integrate AC_PROG_CC_STDC into AC_PROG_CC.
15804 * lib/autoconf/c.m4 (AC_PROG_CC_STDC): Rename to _AC_PROG_CC_STDC.
15805 AU_DEFUN old name. Use _AC_COMPILE_IFELSE.
15806 (AC_PROG_CC): Call _AC_PROG_CC_STDC.

15808 (AC_C_CONST): Same.
15809 (AC_C_INLINE): Same.

15818 _AS_MKDIR_P_PREPARE.
15820 2002-03-28 Kevin Ryde <user42@zip.com.au>
15822 * lib/autoconf/c.m4 (AC_C_INLINE): Test with a typedef return value,
15823 to avoid versions of HP C which don't allow that.
15825 2002-03-27 Paul Eggert <eggert@twinsun.com>
15827 * lib/m4sugar/m4sh.m4 (_AS_BASENAME_PREPARE): New macro.
15828 (AS_SHELL_SANITIZE): Invoke it.
15829 (AS_BASENAME): AS_REQUIRE it, and use $as_basename.

15835 2002-03-26 Akim Demaille <akim@epita.fr>
15837 * doc/autoconf.texi (Introduction): The GNATS base moved.
15839 2002-03-25 Paul Eggert <eggert@twinsun.com>
15841 * tests/m4sh.at: Don't rely on "PATH=test:$PATH test-1" working
15842 as POSIX requires, as it doesn't work with Zsh.
15843 * doc/autoconf.texi (Assignments): Document the problem.
15845 2002-03-25 Alexandre Duret-Lutz <duret_g@epita.fr>
15847 * doc/autoconf.texi (Limitations of Make): Mention more issue
15848 about VPATH, overriding of macros in sub-makes, and handling of
15851 2002-03-21 Paul Eggert <eggert@twinsun.com>
15853 * doc/autoconf.texi (Here-Documents): Mention Solaris 8 dtksh
15854 problem with here-document buffer boundaries.
15856 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Unset ENV and BASH_ENV
15857 when reinvoking the shell, to work around problems with installers
15858 who put strange things like "cd" commands in their environments.
15860 2002-03-19 Akim Demaille <akim@epita.fr>
15862 * tests/semantics.at (AC_C_BIGENDIAN): s/unknow/unknown/.

15874 From Nishio Futoshi.
15876 2002-03-19 Akim Demaille <akim@epita.fr>
15878 * lib/m4sugar/m4sugar.m4 (m4_define_default, m4_fst, m4_map): New.

15882 * doc/autoconf.texi (Programming in M4sh): Add AS_MKDIR_P.
15883 (Limitations of Usual Tools): Add mkdir section.
15885 * lib/m4sugar/m4sh.m4 (_AS_MKDIR_P_PREPARE): New macro.
15886 (AS_MKDIR_P): Require it. Use mkdir -p if available, falling
15887 back on AS_DIRNAME to compute prefixes otherwise; this is
15888 roughly what mkinstalldirs does. That way, we need not have
15889 our own filename disassembler. The old disassembler did not
15890 work with Solaris 8 dtksh, which is ksh Version M-12/28/93d.
15892 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP):
15893 Create at_test_all by a series of assignments,
15894 not by a single assignment of a long string. The latter causes ksh
15895 version 11/16/88g to silently misbehave on OpenServer 5.0.6a,
15896 presumably because of a buffer overrun.
15898 2002-03-14 Paul Eggert <eggert@twinsun.com>
15900 * lib/autotest/general.m4 (at_times_skip):
15901 Renamed from at_times. Now a boolean.
15902 ksh93 Version M-12/28/93d doesn't like 'x=times; $x'; it
15903 says 'times: not found'.
15905 2002-03-14 Akim Demaille <akim@epita.fr>
15907 * bin/autoreconf.in (&study_gettextize): New.
15908 (&autoreconf): Handle newest gettextize.

15932 2002-03-11 Andreas Schwab <schwab@suse.de>
15934 * configure.ac: Explicitly check for EMACS since AM_PATH_LISPDIR
15935 does not do it if --with-lispdir is given.

15944 subdirectory should exist.
15946 2002-03-08 Akim Demaille <akim@epita.fr>
15948 * Makefile.am (AUTOMAKE_OPTIONS): 1.6.
15950 2002-03-08 Akim Demaille <akim@epita.fr>
15952 * bin/autom4te.in (&handle_m4): Do not foreach with `$_' as it
15953 aliases the actual variables, and modifications of the former
15956 2002-03-08 Akim Demaille <akim@epita.fr>
15958 * bin/autom4te.in (&handle_m4): Protect us from corrupted file
15959 because of C-c: have m4 output in tmp files, then mv them.
15961 2002-03-08 Akim Demaille <akim@epita.fr>

15982 * doc/autoconf.texi (AC_LIBOBJ vs. LIBOBJS): New.
15983 * lib/autoconf/general.m4 (AC_INIT): More informative error
15984 message for LIBOBJ.
15986 2002-03-04 Akim Demaille <akim@epita.fr>

15991 2002-03-04 Akim Demaille <akim@epita.fr>
15993 * doc/autoconf.texi (Transforming Names): Equality between target
15994 and host is irrelevant.
15995 (Specifying Names, Canonicalizing): Remove all references to the
15996 backward compatibility hooks. Rather, collect them all into...
15997 (Hosts and Cross-Compilation): this new section.
15998 * doc/install.texi (System Type): Ditto.
15999 * lib/autoconf/general.m4 (AC_CANONICAL_HOST): Explicitly state
16000 that `--host' implies cross-compilation.
16002 2002-03-04 Akim Demaille <akim@epita.fr>
16004 * doc/autoconf.texi (Evaluation Macros): New.
16005 * lib/m4sugar/m4sugar.m4 (m4_lquote): Remove, it is totally
16007 (_m4_foreach): Define the variant with immediate evaluation so
16008 that it contains exactly the items, not an expression which
16009 evaluation is the current item.
16010 (m4_re_string, m4_re_word): Don't over quote them.
16012 2002-03-04 Akim Demaille <akim@epita.fr>
16014 Instead of having stacking `shift's evaluated at the end, let
16015 `foreach' loops immediately evaluate them.
16017 * lib/m4sugar/m4sugar.m4 (m4_quote, m4_dquote): Use $@ rather than
16018 $*. This is the n-th time I change my mind, but hopefully this is
16021 (m4_text_wrap): Use m4_foreach, which is finally correct _and_
16023 (m4_foreach_quoted, m4_car_quoted, _m4_foreach_quoted): Remove, as
16024 it was only a hack for m4_text_wrap.
16025 (m4_car2): Remove, replaced by...
16027 (_m4_foreach): Adjust.
16028 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Adjust, and use
16029 m4_bpatsubst for clarification.

16078 2002-02-07 Akim Demaille <akim@epita.fr>
16080 Fix Autoconf PR/207:
16081 AC_PREFIX_PROGRAM fails with dashed program names
16083 * lib/autoconf/general.m4 (AC_PREFIX_PROGRAM): Just use a fresh
16084 variable when looking for the prefix program.
16085 Now it also works for shell variables.

16120 2002-02-05 Akim Demaille <akim@epita.fr>
16122 * tests/Makefile.am (check_SCRIPTS): Use it, instead of WRAPPERS,

16142 2002-02-05 Akim Demaille <akim@epita.fr>
16144 * bin/autom4te.in (&parse_args): Implement `frozen files are
16145 optional are the sum of the previous files on the command line'.
16146 Also, pass `--reload-state=' on them, so...
16147 (handle_m4): don't.
16148 * lib/autom4te.in (Autotest, Autoconf): Rely on M4sh.
16149 (M4sh): Rely on M4sugar.
16150 (Autotest, M4sh, M4sugar): Use frozen files.
16152 2002-01-31 Akim Demaille <akim@epita.fr>

16162 2002-01-30 Akim Demaille <akim@epita.fr>
16164 * tests/semantics.at (AC_CHECK_SIZEOF): Split into two tests: one

16166 is now run with GCC only.

16174 change AC_INIT default values.
16176 2002-01-29 Akim Demaille <akim@epita.fr>
16178 * tests/torture.at (Configuring subdirectories): Use configure.in,
16179 so that aclocal 1.4 works.
16180 Reported by Alexandre Duret-Lutz and Larry Schmitt.
16182 2002-01-28 Akim Demaille <akim@epita.fr>
16184 * doc/autoconf.texi (Writing testsuite.at): AT_CLEANUP no longer
16187 2002-01-28 Akim Demaille <akim@epita.fr>
16189 * lib/autotest/general.m4 (AT_INIT): Don't be ridiculous: adjust
16190 AUTOTEST_PATH *after* it was set.
16191 Don't put `.' in the PATH: the user should be precise and `./' if
16192 needed. In addition, given that the test suite does some `cd', if
16193 `.' is in the path, the `tested programs' sections will report
16194 programs found in the test suite's directory, while during the
16195 tests (performed in their own directory), these programs are no
16196 longer visible. In other words, the results is confusing and
16198 * tests/m4sh.at: Adjust: don't rely on `.' being in the PATH.

16264 package.m4, since is really depends upon configure.ac, not
16266 * doc/autoconf.texi (testsuite Scripts): Adjust.
16267 * tests/Makefile.am (package.m4): New.
16268 EXTRA_DIST it since its a source.
16270 2002-01-06 Akim Demaille <akim@epita.fr>
16272 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Move the AC_SUBST
16273 of PACKAGE_NAME, PACKAGE_TARNAME, PACKAGE_VERSION, PACKAGE_STRING,
16274 and PACKAGE_BUGREPORT from here...
16275 (_AC_INIT_DEFAULTS): to here, since it is unrelated to the
16277 (_AC_INIT_PREPARE): AC_DEFINE these symbols.
16278 * lib/autotest/general.m4: Use AT_PACKAGE_*, not PACKAGE_*.
16279 (AT_INIT): No longer catch `^PACKAGE_(BUGREPORT|STRING)$'.

16302 2001-12-14 Akim Demaille <akim@epita.fr>
16304 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): We cleaning up the
16305 trailing files, don't apply `-rf' to files which might not be
16306 created by configure (core, core.*, and *.core), but just `rm -f'.
16307 Suggested by Jonathan Kamens.
16309 2001-12-14 Aaron M. Ucko <amu@alum.mit.edu>
16311 * lib/autoconf/general.m4: Avoid duplicates in `$ac_configure_args'.

16315 * Makefile.am (MAINTAINERCLEANFILES): Remove configure.
16317 2001-12-13 Peter Eisentraut <peter_e@gmx.net>

16320 abs_builddir, top_buildpath to abs_top_builddir, srcpath to
16321 abs_srcdir, top_srcpath to abs_top_srcdir.
16322 (_AC_OUTPUT_FILES): Adjust.
16323 * NEWS, doc/autoconf.texi, lib/autoconf/autotest.m4,

16333 2001-12-12 Kevin Ryde <user42@zip.com.au>
16335 * doc/autoconf.texi (File Descriptors): Use a clearer layout for the
16336 forbidden file descriptors table.
16338 2001-11-26 Akim Demaille <akim@epita.fr>
16340 * bin/autoscan.in (%c_keywords): Build it at top level.
16341 Map to 1 in order to simplify its uses.

16346 Remove $filepath, useless.
16347 (&scan_makefile): Don't remove the $(FOO), ${FOO} and @FOO@
16348 variables, they are really part of the tokens.
16349 Split the input line on spaces and then look for tokens.
16350 Now autoscan ceases to ask for AC_PROG_LEX for the package Bison
16351 because of `lex$U.$(OBJEXT)'.
16352 (&scan_files): Use "@list" instead of join.
16353 * doc/Makefile.am (CLEANFILES): Add *.fns.

16358 Remove, replaced by...
16359 * tests/wrappl.in: Be common for all the Perl executables.
16360 In particular autoscan and autoheader want -I.
16361 * configure.ac: Adjust.
16362 * lib/autoscan/headers: errno.h is portable.
16364 2001-11-26 Akim Demaille <akim@epita.fr>
16366 * bin/autoscan.in (used): New.
16369 2001-11-26 Akim Demaille <akim@epita.fr>
16371 * bin/autoscan.in (&scan_c_file): Better parsing of CPP
16373 (&scan_sh_file): Remove a duplicate pattern.
16374 (&check_configure_ac): Use long options.

16380 Before, having a line containing the opening of a multi line
16381 comment made the whole line be ignored.
16383 2001-11-26 Akim Demaille <akim@epita.fr>
16385 * doc/autoconf.texi (Using an Autotest Test Suite): New.

16391 Test groups are now run two directories deeper.
16393 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Replace srcdir,
16394 top_srcdir and top_builddir with at_srcdir, at_top_srcdir and
16396 * lib/autotest/general.m4 (AT_INIT): Compute srcdir,
16397 top_srcdir, builddir and top_builddir.
16398 Use `at_*dir' relatively to the directory containing the
16399 suite, use `*dir' when relatively to the current group dir.
16401 2001-11-25 Joseph S. Myers <jsm28@cam.ac.uk>
16403 * doc/autoconf.texi, TODO, lib/autoconf/fortran.m4,
16404 lib/autoconf/functions.m4, lib/autoconf/headers.m4,
16405 tests/atgeneral.m4, tests/tools.at, tests/atspecific.m4: Fix
16408 2001-11-22 Alexandre Duret-Lutz <duret_g@epita.fr>
16410 * doc/autoconf.texi (Using System Type): Add an example of `case
16411 $host' usage so people quit using `case $target' everywhere.
16413 2001-11-22 Akim Demaille <akim@epita.fr>
16415 * doc/autoconf.texi (Installation Directory Variables): Englishoes
16416 spotted by Jim Meyering.
16418 2001-11-16 Paul Eggert <eggert@twinsun.com>
16420 This patch implements a `long double' suggestion by Oliver Kiddle.
16422 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C)): Make the array
16423 static, to catch errors if the value isn't known at compile-time
16424 and the compiler supports dynamic arrays. Change its name from
16425 `_array_' to `test_array' to avoid potential name clashes.
16426 (AC_C_LONG_DOUBLE): Make it a compile-time test, not a run-time
16427 test. Do not define HAVE_LONG_DOUBLE if `long double' is no
16428 better than double. Catch a bug in GCC 2.95.2 x86.
16429 * doc/autoconf.texi (C Compiler): Document the above.
16432 2001-11-13 Akim Demaille <akim@epita.fr>
16434 * tests/m4sh.at (LINENO): Protect from autom4te's substitution by
16436 * tests/tools.at: Don't protect dnl, AT_DATA_M4SH does.
16438 2001-11-13 Akim Demaille <akim@epita.fr>
16440 * lib/autotest/general.m4 (AT_INIT): After having run the test
16441 group, go back to the initial directory, not to at_suite_dir.
16443 2001-11-13 Akim Demaille <akim@epita.fr>
16445 * tests/atspecific.m4 (AT_DATA_M4SUGAR, AT_DATA_M4SH)
16446 (AT_DATA_AUTOCONF): Also protect @&t@ from autom4te.
16447 (AT_CHECK_AUTOCONF, AT_CHECK_AUTOHEADER): Pass no --include
16449 (AT_CHECK_CONFIGURE): Use absolute paths.
16450 (_AT_CHECK_AC_MACRO): Create aclocal.m4 with AC_STATE_SAVE in it.
16451 The problem is still the old one: there is no means in M4 (that I
16452 know about) to create a defining macro, because there is no means
16453 to create `$1' etc., therefore, the defining macro ``swallows''
16454 all the arguments meant to the defined macro.
16456 2001-11-13 Akim Demaille <akim@epita.fr>
16458 * tests/atspecific.m4 (AT_DATA_AUTOCONF): New.
16459 (AT_CONFIGURE_AC): Output the definition of AC_STATE_SAVE in
16461 * tests/aclocal.m4: Remove, as it is no longer used.
16463 2001-11-13 Akim Demaille <akim@epita.fr>
16465 * lib/autotest/general.m4: Change `tests?' into `groups?' in
16466 variable names when referring to a single test group, or to
16467 `suite' when referring to the whole test suite.
16468 `at_last_test' is removed: m4 compute at_format itself.
16469 (at_stdout, at_stder1, at_stderr): New variables.
16470 (AT_CHECK): Use them.
16472 2001-11-13 Akim Demaille <akim@epita.fr>
16474 * lib/autotest/general.m4 (AT_INIT): Be sure to put `.', relative,
16476 Create `testsuite.dir/003/run' instead of `testsuite.003'.
16477 Do it as soon as a test fails, don't wait till the end of the test
16479 Don't remove $as_me.[0-9]*, since these files no longer exist.
16481 2001-11-13 Akim Demaille <akim@epita.fr>
16483 * tests/tools.at: Use absolute paths, since we are no longer run
16486 2001-11-13 Akim Demaille <akim@epita.fr>
16488 Now that tests are running in their own private dir, there is no
16489 need to list the files to remove at the end of tests groups.
16491 * lib/autotest/general.m4 (_AT_CLEANUP_FILE, AT_CLEANUP_FILES):
16492 (AT_data_files, at_data_files): Remove.
16493 (AT_CLEANUP, AT_DATA): Simplify.
16495 Remove the group dir if !debug && !failed.
16496 * tests/atspecific.m4: Adjust.
16498 2001-11-13 Akim Demaille <akim@epita.fr>
16500 Start a new layout for Autotest: `testsuite' creates
16501 `testsuite.dir' in which the at-check-line etc. files are to be
16502 found, and `testsuite.dir/003' where the test group 3 is run.
16504 * lib/autotest/general.m4 (AT_INIT): at_tests_dir,
16505 at_check_line_file, at_format, at_test_normalized, at_group_dir
16507 Create the directories.
16508 Use absolute paths for at- files.
16509 (AT_CHECK): Adjust.
16511 2001-11-11 Michael Matz <matz@kde.org>
16513 * m4sugar.m4 (_m4_foreach): Make it linear instead quadratic.
16515 (m4_car): Properly quote arguments.
16517 2001-11-13 Akim Demaille <akim@epita.fr>
16519 * tests/aclocal.m4 (AC_STATE_SAVE): s/LIBOBJS/LIB@&t@OBJS/ to cope
16520 with stricter rules on LIBOBJS.
16522 2001-11-12 Paul Eggert <eggert@twinsun.com>
16524 * lib/autoconf/c.m4 (AC_C_PROTOTYPES): Define __PROTOTYPES too.
16525 * doc/autoconf.texi (C Compiler): AC_C_PROTOTYPES now defines
16528 2001-11-12 Akim Demaille <akim@epita.fr>
16530 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT): Use AC_CHECK_FUNCS.
16532 2001-11-12 Akim Demaille <akim@epita.fr>

16535 * lib/autoconf/functions.m4, lib/autoconf/general.m4,
16536 * lib/autoconf/headers.m4, lib/autoconf/libs.m4,
16537 * lib/autoconf/programs.m4, lib/autoconf/specific.m4,
16538 * lib/autoconf/types.m4: When invoking AC_DEFINE and friends,
16539 specify to what the macro should be defined (typically to 1).
16541 2001-11-12 Akim Demaille <akim@epita.fr>
16543 * lib/autoconf/functions.m4 (AC_FUNC_STRTOD): AC_SUBST POW_LIB.
16546 2001-11-12 Akim Demaille <akim@epita.fr>
16548 * lib/autoconf/programs.m4 (_AC_PROG_LEX_YYTEXT_DECL): Use
16549 AC_TRY_EVAL to run $LEX, not AC_TRY_COMMAND. This validates the
16550 definition used by Automake where LEX is +/- "${missing} lex" and
16551 `missing' itself contains variables.
16553 2001-11-12 Akim Demaille <akim@epita.fr>
16555 * lib/autotest/general.m4 (AT_INIT): Push KILL at the end.
16556 Now that M4sh pushes BODY, the comments were output at the end of
16559 2001-11-08 Akim Demaille <akim@epita.fr>
16561 * bin/autoreconf.in (&autoreconf): Run aclocal before tracing, so
16562 that we can trace macros from aclocal.m4.
16563 Trace AC_PROG_LIBTOOL, not AM_PROG_LIBTOOL, since the latter is
16564 obsoleted, and redirect to the former anyway.
16565 Reported by Ralf Corsepius.
16567 2001-11-08 Akim Demaille <akim@epita.fr>
16569 * bin/autoreconf.in (&autoreconf): AC_CONFIG_SUBIDRS are to be
16570 processed only if present.
16571 * tests/torture.at (Configuring subdirectories): Use autoreconf
16572 instead of successive calls to autoconf.
16573 Add a nonexistent subdirectory to exercise the patch above.
16574 Reported by Ralf Corsepius.
16576 2001-11-08 Kevin Ryde <user42@zip.com.au>
16578 * doc/autoconf.texi (Limitations of Usual Tools): Note HP-UX cc

16586 * bin/autom4te.in (warn_forbidden): New.
16587 (handle_output): Use it.
16588 Read m4_pattern_forbid with messages.

16592 * bin/autom4te.in (--normalize): Remove.
16593 * lib/autom4te.in: Adjust.
16595 2001-11-05 Akim Demaille <akim@epita.fr>
16597 * tests/Makefile.am (testsuite): Rename this target as...
16598 ($(TESTSUITE)): this.
16601 2001-11-05 Alexandre Duret-Lutz <duret_g@epita.fr>
16603 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): When removing
16604 the --prefix option, also remove it's argument.
16606 2001-11-05 Akim Demaille <akim@epita.fr>
16608 * doc/autoconf.texi (testsuite Invocation): Update.
16609 (Writing testsuite.at): Update.

16618 (&file_name_is_absolute): New, wrappers around routines from
16620 Use and export them.
16621 (&find_configure_ac): Optionally take a directory where to look at.
16622 * bin/autoreconf.in (&parse_args): Trim the configure.ac part of
16624 Default @ARGV to `.', not find_configure_ac.
16625 (&autoreconf): Argument is a directory.
16626 Trace AC_CONFIG_SUBDIRS and schedule the subdirs for autoreconf'ing.
16627 * doc/autoconf.texi (autoreconf Invocation): Update.

16636 Don't look for aclocal flags if we already know aclocal is not
16638 Move aclocal.m4t only if it exists.
16639 Reported by Ezra Peisach.
16641 2001-11-03 Akim Demaille <akim@epita.fr>
16643 * bin/autoreconf.in (&parse_args): Work only on the configure.ac
16644 passed on command line, defaulting to ./configure.ac if present.
16645 (&maybe_autoreconf, File::Find): Remove, unused.
16646 (&autoreconf): If autoconf is not used, don't try to trace.
16648 2001-11-02 Akim Demaille <akim@epita.fr>

16665 Don't run aclocal when aclocal.m4 is not from aclocal.
16667 Don't run libtoolize and gettextize if --install is not given.
16669 2001-11-01 Paul Eggert <eggert@twinsun.com>
16671 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): _AS_CR_PREPARE needs to
16672 be invoked before _AS_LINENO_PREPARE.
16673 (_AS_LINENO_PREPARE): Use as_cr_digits and as_cr_alnum rather
16674 than character ranges.
16676 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Fix NLS before
16677 invoking AS_BASENAME. Set the locale variables to 'C' if
16678 possible, as POSIX requires this to get the traditional

16685 with {}, as that triggers a bug in Bash 2.05.
16687 (_AS_LINENO_PREPARE): Use Sed rather than
16688 Awk. Fix the sed prepass to work even if there are multiple
16689 instances of $LINENO on the same line. Do not substitute for
16690 other variables like $LINENOT. Do not check file dates; such a
16691 check is unreliable on sufficiently fast machines, and removing
16692 the check makes the code simpler and more reliable. Check for
16693 output and chmod failures.
16695 * doc/autoconf.texi (Special Shell Variables): Document
16698 2001-10-31 Akim Demaille <akim@epita.fr>
16700 * tests/Makefile.am (atconfig): Remove this target, Automake
16703 2001-10-31 Akim Demaille <akim@epita.fr>
16705 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Do not
16706 AC_CONFIG_FILES(atlocal) as it means a file atlocal.in *must* be
16707 provided, while it is optional.
16708 * configure.ac: Adjust.
16710 2001-10-26 Paul Eggert <eggert@twinsun.com>
16712 * NEWS, README, configure.ac, lib/Autom4te/General.pm,
16713 lib/Autom4te/Struct.pm:
16714 Require Perl 5.005_03 instead of just 5.005, as some tests fail
16717 * doc/autoconf.texi (Special Shell Variables): Document some
16718 more LINENO gotchas, particularly with respect to the Awk+Sed hack.
16720 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): New macro.
16721 (_AS_LINENO_PREPARE): Use it instead of shell eval, since
16722 eval $LINENO is not portable in practice.
16724 2001-10-24 Akim Demaille <akim@epita.fr>
16726 * lib/Autom4te/General.pm (backname): New.
16728 2001-10-24 Akim Demaille <akim@epita.fr>

16738 2001-10-22 Paul Eggert <eggert@twinsun.com>
16740 * lib/autoconf/functions.m4 (AC_FUNC_STRERROR_R):
16741 Rename ac_cv_func_strerror_r_works to ac_cv_func_strerror_r_char_p,
16742 and rename HAVE_WORKING_STRERROR_R to STRERROR_R_CHAR_P, since
16743 POSIX decided to standardize on the int flavor of strerror_r.
16744 Always do char* test, as there's no reason not to.
16745 Assign to a char* var, to catch strerror_r that returns int*.
16747 * doc/autoconf.texi (Particular Functions):
16748 Document the above changes. Also, document the fact that
16749 AC_FUNC_STRERROR_R defines HAVE_DECL_STRERROR_R.
16751 * NEWS: Mention HAVE_WORKING_STRERROR_R -> STRERROR_R_CHAR_P.
16753 2001-10-20 Akim Demaille <akim@epita.fr>

16764 (&autoreconf): Display the full path of the configure.ac we are
16766 Trace it only once.
16767 Be sure to honor --force with gettextize.
16768 Always run aclocal.
16769 * doc/autoconf.texi: Adjust.
16771 2001-10-20 Akim Demaille <akim@epita.fr>
16773 * bin/autoheader.in ($localdir, $m4, $SIMPLE_BACKUP_SUFFIX):
16775 * bin/autoreconf.in (&autoreconf): Do not run gettextize when
16776 `intl' is already present, as it refuses unless --force.
16777 (&parse_args): Use -I, --include instead of the old Autoconf
16779 ($localdir, $autoconf_dir): Remove.
16781 (&maybe_autoreconf): New, to preserve $_ for File::Find.
16783 2001-10-19 Jens Petersen <petersen@redhat.com>
16785 * lib/autoconf/programs.m4 (AC_PROG_AWK): Prefer gawk to mawk.

16804 configure.ac being studied.
16806 2001-10-18 Paul Eggert <eggert@twinsun.com>
16808 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Cast sizeof to unsigned
16809 long, to work around a bug in the HP C compiler version HP92453-01
16812 * lib/m4sugar/m4sh.m4 (AS_DIRNAME): Use 'dirname' if that works.
16813 (AS_BASENAME_EXPR): New macro.
16814 (AS_BASENAME_SED): Do not assume GNU sed semantics.
16815 (AS_BASENAME): Use 'basename' if that works; then try 'expr';
16816 and fall back on 'sed' only if the other two fail. This makes
16817 AS_BASENAME act more like AS_DIRNAME.
16818 (as_me): Shell-quote the argument of AS_BASENAME, in case $0
16819 contains white space.
16820 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR):
16821 Use AS_DIRNAME, since I think it's now DOS-friendly.
16822 * tests/m4sh.at (DIRNAME_TEST): New arg $3.
16823 Allow "dirname //FOO" to return either / or //, as POSIX allows
16826 2001-10-10 Akim Demaille <akim@epita.fr>
16828 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Recognize

16834 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N_PREPARE): m4_defun, not

16872 (Syntax of the shell scripts): Don't.
16873 * bin/autoheader.in, bin/autom4te.in, bin/autoreconf.in: Don't
16874 bother with $force since...
16875 * lib/Autom4te/General.pm: does.
16877 2001-10-08 Akim Demaille <akim@epita.fr>
16879 * bin/autoreconf.in: Rewrite in Perl.
16880 * configure.ac: Adjust.

16964 empty, and if we can find a shell that does support LINENO,
16965 then set CONFIG_SHELL to that shell and then re-execute
16966 ourselves with CONFIG_SHELL.

16970 * tests/Makefile.am (clean-local): Don't invoke $(TESTSUITE) if it

17053 and invoke a new argument $4 if either is discovered.
17054 This makes _AC_COMPUTE_INT_COMPILE more like _AC_COMPUTE_INT_RUN.
17055 (_AC_COMPUTE_INT): Pass IF-FAILS arg to _AC_COMPUTE_INT_COMPILE.
17057 2001-09-28 Akim Demaille <akim@epita.fr>

17105 * lib/autotest/general.m4 (AT_INIT): Dump the whole config.log.

17198 2001-09-22 Akim Demaille <akim@epita.fr>

17203 `$LINENO' support replacement when not supported.
17204 (_AS_CR_PREPARE, _AS_TR_CPP_PREPARE, _AS_TR_SH_PREPARE): Invoke

17249 arguments. Fixed a typo.
17251 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
17253 * man/Makefile.am (.x.1): Use @PATH_SEPARATOR@, not ':' to set up

17271 2001-09-19 Akim Demaille <akim@epita.fr>
17273 * lib/autotest/general.m4: Englishoes.
17274 From Tim Van Holder and Alexey Mahotkin.
17276 2001-09-18 Paul Eggert <eggert@twinsun.com>
17278 * doc/autoconf.texi (Common Shell Constructs): New node,
17279 documenting AS_DIRNAME.
17280 (Limitations of Usual Tools): Refer to it when discussing dirname.
17281 Also, update discussion of POSIX standard to reflect latest draft.
17283 * lib/autoconf/c.m4:
17284 (AC_LANG_INT_SAVE(C)): Also support negative values, down to LONG_MIN.
17286 * lib/autoconf/general.m4 (_AC_COMPUTE_INT_COMPILE):
17287 Do not pass a first argument with leading '-'
17288 to expr, by parenthesizing initial integers that might be negative.
17290 * doc/autoconf.texi (Particular Functions): AC_FUNC_GETPGRP
17291 now merely checks whether it is an error to pass an argument
17294 * lib/autoconf/functions.m4 (_AC_FUNC_GETPGRP_TEST): Remove.
17295 (AC_FUNC_GETPGRP): Don't bother with a runtime test. Just check
17296 whether it is a (compile-time) error to pass an argument to
17297 getpgrp. This simpler test supports the revised documentation,
17298 and is all that AC_FUNC_GETPGRP's users really need.
17300 2001-09-18 Akim Demaille <akim@epita.fr>
17302 * doc/autoconf.texi (Limitations of Make) <$<>: New.

17312 * tests/m4sh.at: Ensure that AS_DIRNAME handles '/', '//' and '///'
17314 Add test for AS_BASENAME.
17315 * lib/m4sugar/m4sh.m4: Fix AS_BASENAME so that it passes the previous
17316 added test. It now correctly handles /1/2/3/, returning '3' not ''.
17317 Added AS_BASENAME_SED to make the interface the same as AS_DIRNAME.
17318 * tests/base.at: Fixed the expected responses. The old ones were
17320 * lib/autoconf/general.m4: Fixed AC_PREFIX_PROGRAM, it now behaves as
17321 the documentation claims it should (and how it behaved in 2.13).
17323 2001-09-18 Akim Demaille <akim@epita.fr>
17325 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): No INIT-CMDS in
17326 the AC_CONFIG_COMMANDS invocation.
17327 This also solves the name clash problems.
17328 Don't set the package's ID.
17329 * lib/m4sugar/Makefile.am (version.m4): Revamp.
17330 No longer to be shipped.
17331 (version.in): Remove.

17333 * lib/autoconf/status.m4: Adjust.
17334 Use `m4_PACKAGE_STRING'.
17335 * lib/autotest/general.m4 (AT_INIT): N-th signature change: now
17336 the only optional argument is the name of the test suite.
17337 Expect `package.m4' to define the package signature.
17338 * lib/autom4te.in (Autotest): Add `package.m4?'.
17339 * tests/Makefile.am (package.m4): New.
17340 * tests/suite.at: ifnames is a victim.

17344 * lib/autom4te.in (Autoconf): Preselect AM_CONDITIONAL,
17345 AC_LIBSOURCE, AC_CONFIG_FILES.

17347 program version string doesn't match the package's.
17348 * lib/autoconf/general.m4 (AC_CACHE_VAL): Reestablish the space

17359 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):
17360 Always include <stdio.h> and <stdlib.h>. Evaluate
17361 the expression in an extra function before these includes. Call
17362 fprintf "%d" only after ensuring the argument is of type 'int'.
17363 Reported by Wayne Chapeskie <waynec@spinnaker.com>.
17365 2001-09-17 Paul Eggert <eggert@twinsun.com>
17367 Fix bug reported by Paul Townsend on AIX 4.3.3.0 with CFLAGS=-O4
17368 or CFLAGS=-O5. In that case, the linker has a relaxed view of
17369 fatal errors, and AC_CHECK_LIB causes it to include libraries even
17370 when they don't exist.
17372 * lib/autoconf/headers.m4 (AC_HEADER_DIRENT): Use AC_SEARCH_LIBS,
17373 not AC_CHECK_LIB, so that we don't use -ldir or -lx if we don't
17376 * lib/autoconf/specific.m4 (AC_ISC_POSIX): Replace the old, crufty
17377 version with the version used by fileutils 4.1, except use
17378 AC_SEARCH_LIBS, not AC_CHECK_LIB, so that we don't use -lcposix if
17381 * doc/autoconf.texi (AC_ISC_POSIX): Describe new behavior.
17383 2001-09-13 Akim Demaille <akim@epita.fr>

17423 * lib/autotest/general.m4 (AT_INIT): Create and remove
17424 `$as_me.[0-9]+' instead of `debug-[0-9]+.sh', so that multiple
17425 test suites can cohabit.

17429 * tests/mktests.sh: Don't output banners for empty test files.

17481 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Don't pass

17484 * lib/autoconf/programs.m4 (AC_SHELL_PATH_WALK): Use PATH_SEPARATOR.

17535 2001-09-05 Akim Demaille <akim@epita.fr>
17537 Be ready to handle filenames as stupid as `dnl.at', for if even
17538 the maintainer is dumb enough to do that...
17540 * lib/autotest/general.m4 (AT_SETUP, AT_LINE): Demonstrates your
17541 excellence in M4 quotation: consider `__file__' is active.
17543 And BTW, when invoking m4, pass the --include in the right order:
17546 * bin/autom4te.in, bin/autoupdate.in: Use reverse when kingtal to

17635 * bin/autom4te.in (&parse_args): Strip `.' from `@include'.
17636 * bin/autoupdate.in: Use --include, -I, and --force, -f, too.
17637 Use directly autom4te, not autoconf.

17681 `autoheader: `config.hin' is created'.
17682 * tests/tools.at (Syntax of the Perl scripts): Check autoheader.
17684 2001-08-31 Akim Demaille <akim@epita.fr>

17692 Map --localdir, --autoconf-dir onto it.
17693 Forward autom4te's options instead of interpreting them.

17695 There is no such envvar since the inception of autom4te.cfg.

17717 * lib/Autom4te/General.pm (&find_peer): Remove.
17718 * lib/autotest/general.m4 (AT_INIT): `AUTOTEST_PATH=a:b' gives

17721 find the executables for it.

17723 * tests/atlocal.in: Remove all the obscure envvar manipulations.
17725 * tests/atspecific.m4, tests/tools.at: Passing --localdir is
17726 indeed related to running the test suite, while passing
17727 --autoconf-dir and others is related to running non installed
17728 Autoconf executables. So don't do that, leave it to...

17730 * tests/autoscan: New.
17731 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): Don't

17748 Suggested by Paul Eggert.
17750 2001-08-29 Akim Demaille <akim@epita.fr>

17753 download in a tmp dir.
17755 2001-08-29 Akim Demaille <akim@epita.fr>

17777 foo=`(command) 2>/dev/null`

17928 the name of the directory they're in, instead of the filename,

18072 Huh!?!?! There are still some user EOF tags used, which prevents
18073 their use in AC_CONFIG_COMMANDS for instance...

18076 * lib/autotest/general.m4: Rename the EOF tags as `_ACEOF',

18220 2001-08-15 Akim Demaille <akim@epita.fr>
18222 * bin/autom4te.in (@m4_warning): New.

18227 is in the src tree.

18294 2001-08-11 Alexandre Duret-Lutz <duret_g@epita.fr>
18296 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Handle ACTION-IF-TRUE,
18297 ACTION-IF-FALSE, and ACTION-IF-UNKNOWN.
18298 * doc/autoconf.texi (C Compiler Characteristics): Update
18299 documentation for AC_C_BIGENDIAN.

18304 magic values from an object file when cross-compiling.
18305 Based on code by Guido Draheim <Guido.Draheim@gmx.de>.
18307 2001-08-10 Akim Demaille <akim@epita.fr>
18309 * bin/autom4te.in (&handle_output): Don't use `grep' with side
18311 Suggested by Russ Allbery.
18313 2001-08-10 Ralf Corsepius <corsepiu@faw.uni-ulm.de>
18315 * lib/autoconf/general.m4 (_AC_OUTPUT_SUBDIRS): Propagate the
18316 current $prefix to the sub-configures.
18318 2001-08-09 Tim Van Holder <tim.van.holder@pandora.be>
18320 * lib/autoconf/lang.m4: Ignore *.xSYM when looking for an executable
18321 extension (needed on BeOS). Reported by Guido van Rossum.
18323 2001-08-09 Akim Demaille <akim@epita.fr>
18325 * bin/autom4te.in ($icache): Load it only if older than autom4te.
18327 2001-08-07 Akim Demaille <akim@epita.fr>
18329 * lib/autotest/general.m4 (AT_INIT): All the `at-*' are to be
18331 (at-setup-line): Huh? Be a variable `at_setup_line', not a file.
18332 No need to remove the files before and after the each test, before
18333 each test and at the end of the suite is enough.
18334 Display only the children `times', not the shell's.
18335 If the test failed or was skipped, at-times is not available.
18337 2001-08-07 Akim Demaille <akim@epita.fr>
18339 Always produce testsuite.log, including when there are no
18340 failures. This helps getting information on skipped tests, and
18341 duration of the tests. Err, implement the latter btw.
18343 * lib/autotest/general.m4 (AT_INIT): Set up fd 6 for the log.
18344 Dump information on the first run of each test.
18345 (AT_CLEANUP): Create `at-times' containing the duration of the
18348 2001-08-07 Akim Demaille <akim@epita.fr>
18350 The use of `dumpstat' revealed that `len' was used although it
18351 should not. m4_text_wrap was using it, but in the Autoconf world
18352 where it is legal. Hence (i) test M4sh in its own world, not
18353 Autoconf's, and (ii), ahem, fix the bug :)
18355 * lib/autotest/general.m4: Be sure the set good quotes, as tracing
18356 does not like `' instead of [].
18357 (AT_INIT): Forbid `^_?AT_'.
18358 And don't output such tokens.
18359 * tests/Makefile.am (CLEANFILES): Add `script', `script.s4g',
18360 `script.as', and `autom4te.cache'.
18361 Remove `empty' and `macro' which are no longer used.
18362 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): New.
18363 * tests/m4sugar.at: Use it.
18364 * lib/m4sugar/m4sugar.m4: Use `m4_len' not `len'.
18366 2001-08-07 Akim Demaille <akim@epita.fr>

18372 * bin/autom4te.in (handle_output): Typo in quadrigraph substitution.
18374 2001-08-04 Akim Demaille <akim@epita.fr>
18376 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA, AC_FUNC_ERROR_AT_LINE)
18377 (AC_FUNC_FSEEKO, AC_FUNC_OBSTACK): Use AC_LANG_IFELSE, not
18379 * lib/autoconf/headers.m4 (AC_HEADER_MAJOR): Likewise.
18380 * lib/autoconf/fortran.m4 (_AC_LANG_PROGRAM_C_F77_HOOKS)
18381 (AC_F77_MAIN): Likewise.
18383 2001-08-04 Akim Demaille <akim@epita.fr>
18385 Don't rely on M4sugar outputting the patterns in files, since we
18386 might process the output _without_ running m4, hence without these
18389 * lib/m4sugar/m4sugar.m4 (m4_init): No need for `m4_tmpdir'.
18390 * bin/autom4te.in (@Request::includes): Remove, unused.
18391 (@Request::source): Rename as...
18392 (@Request::input): this.
18393 (@preselect): Add `m4_pattern_forbid' and `m4_pattern_allow'.
18394 (&handle_output): Fetch the patterns from the traces.

18396 (&handle_m4): M4sugar no longer wants `m4_tmpdir'.
18397 (m4_pattern_forbid, m4_pattern_allow): Adjust for tracing only.
18399 2001-08-04 Akim Demaille <akim@epita.fr>
18401 `autoconf && autoheader' is sped up. Now, speed up `autoheader &&
18402 autoconf', i.e., in addition to caching traces, cache the output.
18404 * bin/autom4te.in (Request::cache): Rename as...
18405 (Request::id): this.
18406 ($cache, $icache, $tcache, $ocache): New.
18407 (&handle_m4): Save M4 output in the cache instead of $tmp.
18408 (&handle_output): Adjust.
18409 (&up_to_date_p): Check that the output cache is up to date too.
18410 (top level): Run `&handle_m4' iff force or the cache is invalid.
18411 Run `&handle_output' if the output cache is more recent.
18413 2001-08-04 Akim Demaille <akim@epita.fr>
18415 * bin/autom4te.in ($force): New.
18416 (&parse_args, &print_usage): -f, --force is a new option.
18417 (&handle_output): CPP directives might have spaces after `#'.
18418 (&parse_args): The first file only can be frozen.
18420 2001-08-04 Akim Demaille <akim@epita.fr>
18422 Don't let autom4te compute the `include' traces several times:
18423 first check that the trace cache file is up to date, and then
18424 compare its timestamp with that of the output.
18426 * bin/autom4te.in, bin/autoupdate.in, bin/autoscan.in: Normalize
18427 the preamble. Don't require 5.005 as Autom4te::General does it,
18428 and better yet (use `use', not `require'!).
18429 * lib/Autom4te/Struct.pm: Rename the last occurrences of
18430 Class::Struct as Autom4te::Struct.
18431 * lib/Autom4te/General.pm (File::stat): Use it.
18432 (&mtime): New, export it.
18433 * bin/autom4te.in: Use it.
18434 Declare `$req' is invalid if it is outdated.
18435 Don't declare it valid before saving it if something went wrong.
18437 2001-08-04 Akim Demaille <akim@epita.fr>

18440 must be proposed to the users.
18442 * bin/autom4te.in (@required_trace): Remove.
18444 (&parse_args, &print_usage): -p, --preselect is a new option.
18445 (&up_to_date_p): Adjust.

18472 (%m4_builtin_alternate_name): New.
18473 (&parse_args): Complete the trace requests with alternate names.

18485 (m4_divert_pop): Dump the whole diversion stack when a diversion
18487 * bin/autom4te.in (&handle_output): Remember of the first
18488 occurrence of a possibly undefined macro, not the last.
18489 Complain about the possibly undefined macros in the same order as
18490 the appear in the output.
18491 * lib/autoconf/Makefile.am (autoconf.m4f): List its dependencies.
18492 * tests/tools.at (autoconf: forbidden tokens, basic)
18493 (autoconf: forbidden tokens, exceptions): No longer sort
18494 autoconf's stderr, as it is now deterministic.
18495 Check that `dnl' is caught.
18497 2001-08-01 Akim Demaille <akim@epita.fr>
18499 * configure.ac: Bump to 2.52c.

18517 `END', as `Autom4te::General::END' will be triggered.
18518 * bin/autoupdate.in, bin/autoscan.in: Improve error messages accuracy.
18519 * bin/autoupdate.in (File::Compare, File::Copy): Use them instead of
18520 system to run `mv', `rm', and `cmp'.
