4466 forks when sanitizing PATH. Always output machine information,
4467 not just when atconfig was located.
4469 Add 'testsuite -C dir'.
4470 * lib/autotest/general.m4 (_AT_ARG_OPTION): Move missing argument
4472 (AT_INIT) <PARSE_ARGS_END>: ...here, since -k always takes
4474 <DEFAULTS>: Delay computation of variables based on $at_dir...
4475 <PREPARE_TESTS>: ...to here, since -C can change $at_dir.
4476 <TESTS>: Re-invoke via absolute name, since -C may be in effect.
4477 <PARSE_ARGS>: Parse new option.
4478 <HELP_TUNING>: Document it.
4479 * tests/autotest.at (Choosing where testsuite is run): New test
4481 (Keywords and ranges): Add test for missing -k argument.
4482 * NEWS: Document this.

4488 build-aux/texinfo.tex: Sync from gnulib.
4489 * doc/fdl.texi, doc/make-stds.texi, doc/standards.texi:
4492 2008-01-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4494 * doc/autoconf.texi (Particular Programs): Do not mention the
4495 Autoconf version in which the AC_PROG_INSTALL change was done.
4496 Suggested by Paul Eggert.
4498 2008-01-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4500 Fix --help=recursive with multiple AC_CONFIG_SUBDIRS.
4501 * lib/autoconf/general.m4 (_AC_INIT_HELP): If, for recursive help
4502 mode, we change to the source directory, also set $ac_pwd so we
4503 do not go back to the build tree for the next config subdir.
4504 * tests/torture.at (Deep Package): Extend test to contain two
4505 config subdirs on the top level.
4507 Fix parallel `maintainer-check'.
4508 * Makefile.am (maintainer-check-tests): Depend on `all'.
4509 Use `$(MAKE) $(AM_MAKEFLAGS)' instead of plain `make'.
4510 * tests/Makefile.am (maintainer-check-c++, maintainer-check-posix):
4512 (maintainer-check): Serialize the testsuite runs.

4536 2008-01-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4538 * tests/Makefile.am (noinst_SCRIPTS): Renamed from
4539 check_SCRIPTS. Building the wrappers for `all' allows help2man
4540 to use them for the manpages.
4541 Report by Benoit Sigoure.
4543 * bin/autoreconf.in: Discard stderr for $autoconf/$aclocal --help.

4557 * lib/m4sugar/m4sugar.m4 (m4_expansion_stack_push, _m4_defun_pro)
4558 (_m4_defun_pro_outer, _m4_defun_epi, _m4_defun_epi_outer)
4559 (m4_require): Use m4_do, not m4_join.
4561 Fix some whitespace tests on cygwin.
4562 * tests/tools.at (autom4te and whitespace in file names): Restore
4563 font-lock. Create $TMPDIR before it might be used.
4565 Fix spurious testsuite failure with M4 1.4.11.
4566 * tests/local.at (AT_CHECK_M4): Cater to new m4 error message.
4568 Optimize AC_REQUIRE.
4569 * lib/m4sugar/m4sugar.m4 (m4_expansion_stack_push, _m4_defun_pro)
4570 (_m4_defun_pro_outer, _m4_defun_epi, _m4_defun_epi_outer)
4571 (m4_require): Avoid extra macro calls.
4573 2007-12-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4575 * tests/torture.at (srcdir): Fix quoting.
4577 Do not pass top_srcdir to configure scripts in testsuite.
4578 * tests/autotest.at (srcdir propagation): Copy install-sh to
4580 (my only test): Drop setting of `top_srcdir'.
4581 * tests/base.at (Input/Output): Likewise.
4582 * tests/local.at (AT_CONFIGURE_AC): Copy install-sh,
4583 config.guess, and config.sub to test source tree.
4584 Drop AC_CONFIG_AUX_DIR setting.
4585 (AT_CHECK_CONFIGURE): Drop setting of `top_srcdir'.
4586 * tests/torture.at (Substitute a 2000-byte string): Drop
4587 AC_CONFIG_AUX_DIR setting, copy install-sh to test source tree.
4588 (Substitute a newline, datarootdir workaround): Likewise.
4589 (Define a newline): Adjust for linenumber changes in configure.ac.
4590 * tests/foreign.at (Libtool): Adjust comment to reflect changes.
4592 * tests/semantics.at (AC_PATH_PROGS_FEATURE_CHECK): Skip test
4593 if `pwd` contains whitespace.
4595 Quote $abs_top_srcdir in tests.
4596 * tests/local.at (AT_CHECK_PERL_SYNTAX): Likewise.
4597 * tests/tools.at (Syntax of the shell scripts): Likewise.
4599 * tests/m4sh.at (LINENO): Quote $0.
4601 Fix testsuite program wrapper for whitespace in `pwd`.
4602 The problem here is that the usual mantra is that command
4603 variables can contain arguments, thus we cannot just escape
4604 $AUTOCONF, $AUTOM4TE etc. The compromise is to put the
4605 $top_builddir/tests directory early in $PATH, so that the
4606 wrappers are found by their plain name.
4607 * tests/wrapper.as: Put $testdir early in $PATH.
4608 (AUTOCONF, AUTOHEADER, AUTOM4TE): Set to plain command names.
4610 Proper config.status --file/--header and $srcdir escaping.
4611 * lib/autoconf/status.m4 (_AC_OUTPUT_MAIN_LOOP): Quote special
4612 characters in $ac_file_inputs.
4613 (_AC_OUTPUT_FILE, _AC_OUTPUT_HEADER): eval $ac_file_inputs
4615 * tests/torture.at (datarootdir workaround): Adjust.
4616 (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS): Extend test.
4618 Fix Autotest for whitespace in `pwd`.
4619 * lib/autotest/general.m4 (AT_INIT)
4620 <at_func_create_debugging_script, Driver Loop>:
4621 Quote $at_group_dir.
4622 * tests/autotest.at (whitespace in absolute testdir): New test.
4624 * lib/autom4te.in: Quote @datadir@.
4626 Proper file name escaping in Autoconf programs and Perl modules.
4627 This includes escaping of characters special to the shell
4628 as well as special to Perl, e.g., leading `<' or `>'.
4629 For example, when $file starts with `>', `open ">$file"'
4630 wrongly tries to append to a different file.
4631 * bin/autoconf.as: Fix quoting for autom4te options.
4632 * lib/Autom4te/General.pm (shell_quote): New function, taken
4633 from coreutils, written by Jim Meyering.
4635 * bin/autom4te.in (files_to_options, handle_m4): Use shell_quote
4637 * bin/autoreconf.in (parse_args): Likewise.
4638 * bin/autoscan.in (main): Likewise.
4639 * bin/autoupdate.in (main): Likewise.
4640 * bin/autoheader.in: Likewise, fixing old insufficient escaping.
4641 * bin/ifnames.in: Likewise, XFile usage fixes.
4642 * tests/tools.at (autom4te and whitespace in file names): Extend
4643 test. Test twice, with special characters allowed on w32, and the
4644 rest. Test leading and trailing whitespace, for `open_quote'.
4645 (autotools and whitespace in file names): New, analogous test.
4646 Reported by Paul Eggert and Benoit Sigoure, additional suggestions
4647 by Russ Allbery and Eric Blake.
4650 * lib/Autom4te/Channels.pm, lib/Autom4te/Configure_ac.pm,
4651 lib/Autom4te/Struct.pm, lib/Autom4te/XFile.pm: Likewise.
4652 * lib/Autom4te/FileUtils.pm (open_quote): New function.
4653 (update_file, contents): Use it.
4655 * Makefile.am (autom4te-update): Rewrite for git.
4657 2007-12-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4659 * doc/autoconf.texi (autom4te Invocation, Autom4te Cache): Fix typos.
4661 Fix copyright years.
4662 * Makefile.am, doc/install.texi, lib/autoconf/fortran.m4,
4663 lib/autoconf/lang.m4, lib/freeze.mk: Likewise.
4665 2007-12-04 Eric Blake <ebb9@byu.net>
4667 Manually resync with gnulib, since 'make cvs-update' no longer works.
4668 * build-aux/config.guess: New upstream version.
4669 * build-aux/config.sub: Likewise.
4671 When using older automake, don't downgrade build-aux/texinfo.tex.
4672 * configure.ac (AM_INIT_AUTOMAKE): Add no-texinfo.tex option.
4673 * doc/Makefile.am (TEXINFO_TEX): Add.
4675 2007-11-27 Paul Eggert <eggert@cs.ucla.edu>
4677 Fix AC_C_BIGENDIAN bug caused by new awk method of substitution.
4678 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Don't comment out the
4679 #undef as this runs afoul of our new way of creating config.h.
4680 Problem reported by Jim Meyering in
4681 <http://lists.gnu.org/archive/html/autoconf-patches/2007-11/msg00164.html>.
4683 2007-11-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4685 Fix autom4te for unusual characters in input file names.
4686 * bin/autom4te.in (files_to_options): Quote active characters
4688 * tests/tools.at (autom4te and white space in file names):
4691 * doc/autoconf.texi (Limitations of Usual Tools) <awk>:
4692 Document that Tru64 awk always splits $0.
4694 2007-11-24 Stepan Kasal <kasal@ucw.cz>
4696 * lib/autotest/general.m4 (AT_INIT): Do not extract the
4697 `#AT_STOP_...' line at the end of each test.
4699 2007-11-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4701 * lib/autotest/general.m4 (AT_INIT): For awk line number
4702 extraction script, ensure `$at_group' has a defined value
4703 even for the empty set, and properly quote its usage inside
4706 2007-11-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4708 * doc/autoconf.texi (Shell Functions): New chapter. Document
4709 IRIX sh $0 issue in functions, move content from ...
4710 (Portable Shell): ... here.
4711 (Shell Script Compiler): Note that shell functions are not
4712 totally unportable any more.
4714 2007-11-22 Stepan Kasal <kasal@ucw.cz>
4715 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4717 * lib/autotest/general.m4 (AT_INIT): Exit awk script after
4718 extracting the line numbers of the last needed test.
4720 2007-11-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4722 * lib/autotest/general.m4 (AT_INIT) <at_func_create_debugging_script>:
4725 2007-11-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4727 Fix IRIX testsuite debugging failures: $0 in functions.
4728 * lib/autotest/general.m4 (AT_INIT) <at_func_create_debugging_script>:
4729 Do not use $0 inside a function, as IRIX sh will set that to the
4730 function name rather than the script invocation name.
4732 2007-11-19 Paolo Bonzini <bonzini@gnu.org>
4733 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4735 * lib/autotest/general.m4 (at_func_test): Use cached line numbers
4736 to extract test scripts.
4737 (AT_INIT): Extract and cache test script line numbers.
4739 2007-11-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4741 * lib/autotest/general.m4: Revert 2007-11-15 patch and
4742 subsequent fixups; the awk -> here-document conversion trashes
4743 performance too much with AIX sh.
4745 2007-11-18 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4747 * tests/local.at: Do not test m4, perl with AT_TESTED.
4749 Diagnose and guard against write errors dealing with config.status.
4750 The general idea is this: all write failures from `configure'
4751 writing `config.status' are indicated by $ac_write_error, which
4752 is only checked at the end. This is safe because config.status
4753 code is not executed before the file is complete. Other write
4754 failures, be they inside config.status, or in sub shell/awk
4755 scripts spawned from configure or config.status, typically need
4756 earlier checking, as their results are used right afterwards.
4757 * lib/autoconf/status.m4 (AC_OUTPUT): Initialize `ac_write_fail'
4758 before writing config.status, check afterwards.
4759 (_AC_OUTPUT_FILES_PREPARE, _AC_OUTPUT_FILE)
4760 (_AC_OUTPUT_HEADERS_PREPARE,_AC_OUTPUT_CONFIG_STATUS):
4761 Set `ac_write_error' for write failures to config.status. Barf
4762 upon write failures to temporary files.
4763 Adjust note about closing and reopening the here-document.
4764 (_AC_OUTPUT_HEADER, _AC_OUTPUT_LINK, _AC_OUTPUT_COMMAND)
4765 (_AC_OUTPUT_MAIN_LOOP): Likewise, adjust note about closing and
4766 reopening the here-document.
4767 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
4768 Ensure `ac_write_error' does not escape into config.status.
4769 Also, add a couple of code paths not yet exercised in the test
4770 suite: a config file with input from stdin, and a config header
4772 Suggestion for catching write errors by Bruno Haible.
4774 2007-11-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4776 Avoid error with Tru64 awk and testsuite lines with many words.
4777 * lib/autotest/general.m4 (AT_INIT): In the awk script that
4778 reads the testsuite, set the field separator to an unusual value,
4779 in order to not run over the limit of 199 fields. Tru64 4.0D awk
4780 even splits the input if $i, i>0, was never accessed in the script.
4782 Revert 2007-10-17 change.
4783 * TODO: Multiline args in config files and headers mean something
4784 different and are not fixed, see
4785 <http://lists.gnu.org/archive/html/autoconf-patches/2007-05/msg00017.html>
4786 Report by Stepan Kasal.
4788 * doc/autoconf.texi (Generic Programs): Fix typo.
4790 2007-11-16 Stepan Kasal <kasal@ucw.cz>
4792 AC_*_TOOL does not canonicalize the prefix
4793 * doc/autoconf.texi (Generic Programs): Do not say that
4794 the *_TOOL macros canonicalize, they simply use the `host_alias'.
4796 2007-11-16 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4798 Diagnose write errors in config.status instantiations.
4799 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE)
4800 (_AC_OUTPUT_HEADER, _AC_OUTPUT_MAIN_LOOP): Bail out
4802 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
4803 Extend test to also check for some write error failures, using...
4804 <AT_CHECK_CONFIG_CREATION_NOWRITE>: ...this new macro.
4805 Report by Bruno Haible.
4808 * lib/autotest/general.m4 (AT_INIT) <at_func_log_failure>: Fix

4816 (_AC_OUTPUT_FILE): Mention it here.
4818 2007-11-15 Paolo Bonzini <bonzini@gnu.org>
4819 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4821 * lib/autotest/general.m4 (at_func_test): Remove.
4822 (AT_INIT): Pre-extract test groups into separate files.
4823 (AT_CLEANUP): Source pre-extracted file instead of calling at_func_test.
4824 Remove at-test-source files together with the $at_group_dir.
4825 * tests/autotest.at (Long test source lines): New test.

4829 Shell functions and variables may share a namespace.
4830 * doc/autoconf.texi (Portable Shell): Mention Solaris sh
4833 2007-11-14 Paul Eggert <eggert@cs.ucla.edu>
4835 * lib/autoconf/types.m4 (_AC_TYPE_LONG_LONG_SNIPPET): Make comment match
4838 2007-11-14 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4840 * lib/autoconf/status.m4: Fix a couple of comment typos.
4842 * lib/m4sugar/m4sh.m4 (AS_TMPDIR): Use $as_me, not $me.
4844 2007-11-13 Jim Meyering <meyering@redhat.com>
4846 Clean up the rule to create "expr".
4847 * tests/Makefile.am (expr): Don't redirect directly to target.
4848 Redirect just once, not for each echo statement.
4849 Use $@, not literal "expr".
4851 2007-11-13 Paul Eggert <eggert@cs.ucla.edu>
4853 Don't worry about preprocessor when testing long long.
4854 See: http://lists.gnu.org/archive/html/bug-gnulib/2007-11/msg00075.html
4855 * doc/autoconf.texi (Preprocessor Arithmetic): New section.
4856 (AC_TYPE_LONG_LONG_INT, AC_TYPE_UNSIGNED_LONG_LONG_INT):
4857 These no longer check for preprocessor flaws.
4858 * lib/autoconf/types.m4 (_AC_TYPE_LONG_LONG_SNIPPET):
4859 Do not check for preprocessor flaws.
4861 2007-11-13 Jim Meyering <meyering@redhat.com>
4863 Adapt dependencies, now that a version change doesn't modify configure.ac
4864 * GNUmakefile: Remove "make clean" kludge.
4865 * lib/m4sugar/Makefile.am (version.m4): Depend on Makefile, not
4867 Don't redirect directly to target.
4868 Use $@, not literal "version.m4".
4870 2007-11-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4872 * doc/autoconf.texi (Making testsuite Scripts): Document
4873 ":;{" shorthand as in previous patch.

4882 * tests/Makefile.am ($(srcdir)/package.m4): Likewise.
4884 2007-11-12 Jim Meyering <meyering@redhat.com>
4886 Add more non-srcdir build support.
4887 * GNUmakefile (dummy): Split a long line.
4888 Add -v option to autoreconf invocation.
4890 Remove the autoreconf-provided INSTALL, so that we regenerate it.
4891 * GNUmakefile (dummy): Remove INSTALL.
4893 Remove racy commands to build scripts in bin/ and tests/.
4894 * man/Makefile.am (.x.1): Now that scripts in bin/ and tests/
4895 are guaranteed to be built, remove the rules that tried to build
4896 them. Before, with a parallel build, these rules could lead to
4897 two processes writing tests/wrapper.in concurrently.
4899 Build in man/ only *after* building in bin/ and tests/.
4900 * Makefile.am (SUBDIRS): The man-page-creation process runs $(MAKE)
4901 in both bin/ and tests/.
4903 Accommodate non-srcdir build-from-checkout.
4904 * build-aux/git-version-gen: Require an additional parameter: $srcdir.
4905 Use git's --git-dir=$srcdir/.git option.
4906 Add quotes, in case tarball_version_file contains shell meta-characters.
4907 * GNUmakefile (_curr-ver): Pass $(srcdir) to git-version-gen.
4908 * configure.ac: Pass "." to git-version-gen.
4910 Avoid spurious test failures due to version skew.
4911 * GNUmakefile (dummy): Run $(MAKE) clean after autoreconf -i.

4943 writable again for the `stderr' file, and ignore errors due to
4944 the attempt to write configure.lineno.

4950 * tests/Makefile.am (package.m4): Adjust target.
4951 Don't redirect directly to $@.
4952 (CLEANFILES): Add package.m4.
4953 ($(TESTSUITE)): Depend on just-built package.m4, not the one
4955 When running $(AUTOTEST), search "." before searching $(srcdir).
4957 Avoid a race condition that would make parallel "distclean" fail.
4958 * tests/Makefile.am (distclean-generic): Replace the default,
4959 automake-provided rule with an identical one, but with an additional
4960 dependency on distclean-local. Simply adding the dependency would
4961 cause automake not to emit the rule at all.
4962 * BUGS: Building with -jN works, now.
4964 Distribute git-version-gen.
4965 * Makefile.am (EXTRA_DIST): Add build-aux/git-version-gen,
4966 since GNUmakefile is distributed, and requires it for dist* rules.
4968 Remove two more generated files from version control.
4969 * INSTALL: Remove generated file.
4970 * lib/autoscan/autoscan.list: Remove generated file.
4972 2007-11-09 Paul Eggert <eggert@cs.ucla.edu>
4974 * GNUmakefile (PATH): Remove stray apostrophes; they become
4975 part of PATH, which isn't wanted here.
4977 2007-11-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4979 New config files output variable `top_build_prefix'.
4980 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Substitute
4982 * doc/autoconf.texi (Preset Output Variables): Document it.
4984 Report by Bob Friesenhahn.
4986 Avoid expr for arithmetic evaluation if the shell accepts $((...)).
4987 * lib/autotest/general.m4 (AT_INIT) <at_func_arith>: New
4988 function, to parametrize arithmetic with expr vs. the shell.
4989 Use it where possible.
4990 Suggestion by Benoit Sigoure.
4992 2007-11-03 Benoit Sigoure <tsuna@lrde.epita.fr>
4994 Adjust the documentation of autotest WRT atlocal.
4995 * doc/autoconf.texi (Making testsuite Scripts): It is not necessary,
4996 when using Automake, to write a rule to produce atlocal, since it's
4997 an AC_CONFIG_FILES. Mention that atlocal.in needs to be
4998 distributed, not atconfig.in.
5000 2007-11-04 Eric Blake <ebb9@byu.net>
5002 Update list information.
5003 * README: Mention new autoconf-commit list.
5004 * doc/autoconf.texi (Introduction): Mention autoconf-commit list.
5006 2007-11-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5008 * lib/autoconf/functions.m4 (_AC_FUNC_MALLOC_IF): Fix comment typo.
5010 * lib/m4sugar/Makefile.am (version.m4): Another bash bug workaround.
5012 * build-aux/.gitignore: Ignore mkinstalldirs.
5014 * doc/autoconf.texi (autoreconf Invocation): Fix an underfull line.
5016 2007-11-03 Jim Meyering <meyering@redhat.com>
5018 s/-/./ in snapshot version string: 2.61a-256-8b556 -> 2.61a.256-8b556
5019 * build-aux/git-version-gen: This syncs from coreutils.
5021 Adjust the build procedure so "make check" works reliably.
5022 * README-hacking: Include an extra step between "make" and
5023 "make check" to ensure that the latter passes.
5025 Use just-built tools, when possible.
5026 * GNUmakefile (PATH): Set and export here, ...
5027 (dummy): ... rather than here.
5029 2007-11-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5030 and Andreas Schwab <schwab@suse.de>
5032 * tests/Makefile.am ($(srcdir)/package.m4): Work around bash
5035 2007-11-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5037 * configure.ac (AC_PREREQ): Require version 2.60, for
5038 AC_PROG_SED, AC_PROG_GREP.
5040 2007-11-02 Benoit Sigoure <tsuna@lrde.epita.fr>
5041 and Jim Meyering <meyering@redhat.com>
5042 and Andreas Schwab <schwab@suse.de>
5043 and Eric Blake <ebb9@byu.net>
5045 Document a bug in GNU Bash with compound commands and redirections.
5046 * doc/autoconf.texi (Limitations of Builtins): Mention that GNU
5047 Bash doesn't properly set $? when `{ ... } >/bad' fails, and give
5050 2007-11-03 Eric Blake <ebb9@byu.net>
5052 Support m4 1.4.5 in testsuite.
5053 * tests/torture.at (Define a newline): Exclude line numbers in
5055 Reported by Ralf Wildenhues.
5057 2007-11-03 Jim Meyering <meyering@redhat.com>
5059 Remove automake-provided files from version control.
5060 * build-aux/elisp-comp: Remove file.
5061 * build-aux/install-sh: Remove file.
5062 * build-aux/missing: Remove file.
5063 * build-aux/mdate-sh: Remove file.
5064 * build-aux/.gitignore: New file.
5065 Suggestion from Ralf Wildenhues.
5067 2007-11-03 Eric Blake <ebb9@byu.net>
5069 Adjust version comparison to account for git snapshot numbers.
5070 * lib/m4sugar/m4sugar.m4 (_m4_version_unletter): Also treat - as a
5071 component separator.
5072 * doc/autoconf.texi (Number processing Macros)
5073 <m4_version_compare>: Document this change.
5074 * tests/m4sugar.at (m4@&t@_version_compare): Test it.
5076 2007-10-30 Bruno Haible <bruno@clisp.org>
5078 * lib/autoconf/types.m4 (_AC_TYPE_LONG_LONG_SNIPPET): New macro,
5079 extracted from AC_TYPE_LONG_LONG_INT and AC_TYPE_UNSIGNED_LONG_LONG_INT.
5080 (AC_TYPE_LONG_LONG_INT, AC_TYPE_UNSIGNED_LONG_LONG_INT): Use it.
5081 Fixes problem with Sun C 5.[0-8] in 32-bit mode, reported in
5082 <http://lists.gnu.org/archive/html/autoconf-patches/2007-10/msg00210.html>
5083 Suggested by Paul Eggert.
5085 2007-10-28 Jim Meyering <meyering@redhat.com>
5087 * README-hacking: Autoconf, Automake, and Perl are required to build.
5088 List Gzip and Tar separately. Suggested by Ralf Wildenhues.
5090 2007-10-28 Jim Meyering <meyering@redhat.com>
5092 README-hacking: Recommend running autoreconf -vi.
5093 * GNUmakefile (dummy): Use autoreconf -i, with appropriate PATH,
5094 so that we use just-built tools when they're available.
5095 Suggestions from Ralf Wildenhues.
5097 2007-10-28 Jim Meyering <meyering@redhat.com>
5099 Make inter-release --version output more useful.
5101 Now, each unofficial build has a version "number" like 2.61a-19-58dd,
5102 which indicates that it is built using the 19th change set
5103 (in _some_ repository) following the "v2.61a" tag, and that 58dd
5104 is a prefix of the commit SHA1.
5105 * build-aux/git-version-gen: New file.
5106 * configure.ac: Run it to set the version.
5107 (AM_INIT_AUTOMAKE): Don't check NEWS here.
5108 * Makefile.am (dist-hook): Arrange so that .version appears only
5109 in distribution tarballs, never in a checked-out repository.
5110 * .gitignore: Add .version here, too. Just in case.
5111 * tests/Makefile.am ($(srcdir)/package.m4): Depend on Makefile,
5112 not configure.ac, now that the version number changes automatically.
5114 Ensure that $(VERSION) is up to date for dist-related targets.
5115 * GNUmakefile: Arrange to rerun autoconf, if the version reported by
5116 git-version-gen doesn't match $(VERSION), but only for dist targets.
5118 2007-10-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5120 Fix `Deep Package' failure with a configure script early in PATH
5121 * tests/torture.at (Deep Package): Add `.' early in PATH.
5122 Report by Jim Meyering.

5146 2007-10-22 Paul Eggert <eggert@cs.ucla.edu>
5147 and Eric Blake <ebb9@byu.net>
5149 * lib/autoconf/c.m4 (AC_C_RESTRICT): Work around Sun C++ compatibility
5150 problem reported by Bruno Haible in
5151 <http://lists.gnu.org/archive/html/bug-autoconf/2007-10/msg00027.html>.
5153 2007-10-22 Eric Blake <ebb9@byu.net>
5155 * doc/autoconf.texi (Particular Types): Mention bug in HP-UX 11.00
5158 2007-10-22 Paul Eggert <eggert@cs.ucla.edu>
5160 Don't check for bug in HP-UX 11.00 cpp.
5161 * lib/autoconf/types.m4 (AC_TYPE_UNSIGNED_LONG_LONG_INT):
5162 Use -1ull rather than -1u, since that causes problems with gnulib; see
5163 <http://lists.gnu.org/archive/html/bug-gnulib/2007-10/msg00329.html>.

5181 escaping of backslash in here-documents.
5183 Fix `Deep Package' test failure on FreeBSD.
5184 * tests/torture.at (Deep Package): Do not add `.' to $PATH
5185 unnecessarily. Do not try running `/bin/sh configure' with a
5186 configure script to be found in $PATH, if the shell does not do
5187 this resolution. Fixes test failure on FreeBSD.
5189 Fix config header generation with AIX awk.
5190 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS_PREPARE): In awk
5191 script, use helper array D_is_set, as `" 0"' does not evaluate
5192 to true for AIX awk.
5194 2007-10-21 Eric Blake <ebb9@byu.net>

5233 array of banner text from a special diversion.
5234 <PARSE_ARGS_END>: No longer need awk to find banners.
5235 <TESTS>: Banners are no longer processed by main driver loop, so
5236 we no longer need case statement.

5335 use $as_myself, not $0.

6413 Document the restrictions on AC_CHECK_ALIGNOF's type argument.
6414 * lib/autoconf/types.m4 (_AC_CHECK_TYPE_NEW):
6415 For C, just try sizeof (TYPE) and sizeof ((TYPE)); if the former
6416 works but the latter doesn't, then it's a valid type.
6417 This lets people use function types and so forth.
6418 For C++ there doesn't seem to be a simple solution, so leave it alone.
6419 (AC_CHECK_SIZEOF): Allow argument to be a variable.
6420 (AC_CHECK_SIZEOF, AC_CHECK_ALIGNOF): Don't bother to invoke

6592 AC_SUBST([MKDIR_P]), so that Automake < 1.10 will pick up its
6593 trace, if a package uses AC_PROG_MKDIR_P explicitly. The actual

6616 2007-01-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6618 * lib/autoconf/programs.m4 (AC_PROG_SED): When closing a pipe
6619 early on the reader side, drop stderr of the input to avoid
6620 `broken pipe' error output; this may happen even with shell
6621 builtin `echo' of some bash versions. Reports by Ian Macdonald
6622 <iamacdo@telkomsa.net> and Sam Sexton <Sam.Sexton@reuters.com>.
6624 2007-01-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

6637 http://lists.gnu.org/archive/html/autoconf-patches/2007-01/msg00077.html
6638 * doc/autoconf.texi (Signed Overflow Examples): Give more
6639 discussion about the allow_superuser_privileges example,
6640 and change it a bit to make things clearer.
6641 (Optimization and Wraparound): Clarify whether the compiler
6642 will generate an infinite loop for the example derived from
6643 Autoconf's mktime test.
6644 (Signed Overflow Advice): Say that -ftrapv is meant for debugging.
6645 Also, clarify unsigned multiplication overflow.
6647 2007-01-04 Eric Blake <ebb9@byu.net>
6649 * bin/Makefile.am (RELEASE_YEAR): New macro.
6650 (edit): Use it to supply correct copyright year to scripts.
6651 * bin/autoconf.as (version): Use it.
6652 * bin/autoheader.in ($version): Likewise.
6653 * bin/autom4te.in ($version): Likewise.
6654 * bin/autoreconf.in ($version): Likewise.
6655 * bin/autoscan.in ($version): Likewise.

6659 2007-01-02 Paul Eggert <eggert@cs.ucla.edu>
6661 * doc/autoconf.texi (Integer Overflow): Revised based on today's
6662 feedback. The most important changes document what happens when
6663 you convert an out-of-range value to a signed integer type, and
6664 say that (sum < a) != (b < 0) reliably detects overflow when sum =
6667 * doc/autoconf.texi (Integer Overflow): Greatly expand and
6668 rewrite, taking notions from the recent discussion on the gcc and
6669 autoconf mailing lists; please see
6670 http://lists.gnu.org/archive/html/autoconf-patches/2006-12/msg00091.html
6671 and follow the many links.
6672 (Integer Overflow Basics, Signed Overflow Examples):
6673 (Optimization and Wraparound, Signed Overflow Advice):
6674 (Signed Integer Division): New sections.
6676 2006-12-28 Steven G. Johnson <stevenj@alum.mit.edu>
6678 * lib/autoconf/general.m4 (AC_DEFINE_TRACE): Don't include
6679 preprocessor macro arguments in traced name.
6680 * doc/autoconf.texi (Defining symbols): Document longstanding
6681 support for AC_DEFINE-ing macros with arguments, and document
6682 behavior when the same variable has multiple AC_DEFINEs.
6683 * lib/autoconf/fortran.m4 (_AC_FC_WRAPPERS): Revert to the
6684 old implementation which AC_DEFINEs the FC_FUNC and FC_FUNC_
6685 macros directly, giving much shorter and simpler code.
6687 2006-12-28 Malcolm Purvis <malcolmp@xemacs.org> (trivial change)
6689 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Insert a
6690 space before "$ac_configure_args" to prevent a 'config.status
6691 --recheck' failure if ac_configure_args doesn't contain a leading
6692 space. This works around a problem with the XEmacs configure.ac,
6693 which uses the (undocumented) ac_configure_args variable
6694 inconsistently with Autoconf.
6696 2006-12-22 Paul Eggert <eggert@cs.ucla.edu>
6698 * lib/autoconf/functions.m4 (AC_FUNC_MKTIME):
6699 Include <limits.h>, and use its INT_MAX to rewrite the
6700 j loop so that it does not overflow 'int'. Problem reported by
6702 <http://lists.gnu.org/archive/html/bug-gnulib/2006-12/msg00084.html>.
6703 Play it safe by shifting left by 1 rather than multiplying by 2,
6704 as GCC is less likely to optimize this away when the value
6705 is signed (when it assumes overflow leads to undefined behavior).
6706 Also, don't assume time_t uses two's complement.
6708 2006-12-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6710 * tests/torture.at (Substitute a 2000-byte string): Avoid using
6711 a 10kB long (multi-line) string literal, OpenServer 5.0.7 ksh
6712 dumps core on it. Report by Tim Rice.
6714 2006-12-18 Steven G. Johnson <stevenj@alum.mit.edu>
6716 * lib/autoconf/general.m4 (AC_ARG_ENABLE): Print help about
6717 --disable-option-checking to --help output even when
6718 AC_PRESERVE_HELP_ORDER is not used.
6719 (_AC_INIT_PARSE_ENABLE2): Print warnings using actual --enable or
6720 --with argument, rather than argument with [-.] replaced by
6722 * NEWS: Fix typo in previous change; the news was in the
6725 2006-12-18 Paul Eggert <eggert@cs.ucla.edu>
6727 * NEWS: Warnings are now generated by default for unknown
6728 --enable-* and --with-* options.
6729 * doc/autoconf.texi (Option Checking): Renamed from
6730 (Configure Option Checking). Tighten up the wording a bit.
6731 (External Software, Package Options): Cross-reference to Option
6732 Checking, and use this to shorten our section.
6733 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Prefer test -n
6734 "$x" to test "x$foo" != x.
6735 * lib/autoconf/status.m4 (AC_OUTPUT): Likewise.
6736 Don't warn if $enable_option_checking is "no".
6737 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Initialize
6738 ac_unrecognized_opts to the empty string.
6739 Don't echo the unrecognized opts, as this might mishandle
6740 backslashes or leading -.
6741 (AC_PRESERVE_HELP_ORDER): Put the --disable-option-checking
6742 usage next to the other --disable-FEATURE options in the
6745 2006-12-18 Steven G. Johnson <stevenj@alum.mit.edu>
6747 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS, _AC_INIT_PARSE_ARGS):
6748 (_AC_INIT_PARSE_ENABLE2, _AC_INIT_HELP, _AC_ENABLE_IF):
6749 Print warning for unrecognized --with and --enable options
6750 (AC_DISABLE_OPTION_CHECKING): New macro to disable warnings.
6751 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS, _AC_OUTPUT_SUBDIRS):
6752 Disable option checking when subdirs are configured.
6753 (AC_OUTPUT): If warnings are enabled, print warning about
6754 unrecognized --with and --enable options at the end of
6755 the configure output (as well as at the beginning).
6756 * doc/autoconf.texi (Option Checking): New node.
6757 Document new option warning functionality.
6759 2006-12-16 Eric Blake <ebb9@byu.net>
6761 * configure.ac (AC_INIT): Bump version, since 2.61a is released.
6762 * NEWS: Start news for current version.
6764 2006-12-15 Paul Eggert <eggert@cs.ucla.edu>
6766 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT):
6767 Define HAVE_GETMNTENT to 1, not to the empty string.
6768 Problem originally reported by Jochen Friedrich in
6769 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=403243>.
6771 This change prompted by a problem report by Andrey Simonenko in
6772 <http://lists.gnu.org/archive/html/bug-autoconf/2006-12/msg00026.html>.
6773 * doc/autoconf.texi (Defining Symbols): AC_DEFINE works for
6774 object-like macros only, in the traditional portable character
6776 * lib/autoconf/general.m4 (AC_DEFINE_TRACE_LITERAL):
6777 Warn about attempts to define things that are not identifiers.
6778 * lib/autoconf/fortran.m4 (_AC_FC_WRAPPERS): Rewrite to avoid
6779 awful hack that AC_DEFINEd macro names containing parentheses.
6781 2006-12-12 Paul Eggert <eggert@cs.ucla.edu>
6783 * doc/autoconf.texi: Undo some of the 2006-12-10 change. It was
6784 too drastic, even if Texinfo in theory requires it for info mode.
6786 (config.status Invocation): Renamed back from Recreating a
6788 (Obsolete config.status Use): Renamed back from Obsolete Recreation.
6789 (Autoconf 2.13): Renamed back from 20th-century Autoconf 2.
6791 2006-12-11 Paul Eggert <eggert@cs.ucla.edu>
6793 * NEWS: Version 2.61a.
6795 2006-12-11 Paul Eggert <eggert@cs.ucla.edu>
6796 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6798 * NEWS: Document changes with echo and printf, and the lack
6799 of limits on the total size of multi-line values of substituted
6800 variables, and the AC_FUNC_FSEEKO fix.
6802 2006-12-10 Paul Eggert <eggert@cs.ucla.edu>
6804 * doc/autoconf.texi (Writing Autoconf Input): Renamed from
6805 Writing configure.ac.
6806 (Autoconf Input Layout): Renamed from configure.ac Layout.
6807 (Recreating a Configuration): Renamed from config.status Invocation.
6808 (Obsolete Recreation): Renamed from Obsolete config.status Use.
6809 (acconfig Header): Renamed from acconfig.h.
6810 (20th-century Autoconf 2): Renamed from Autoconf 2.13.
6811 (Writing Testsuites): Renamed from Writing testsuite.at.
6812 (Autom4te Cache): Renamed from autom4te.cache.
6814 * BUGS: Remove mention of VPATH problem, since it's now documented
6815 not to be a bug in the Autoconf build procedure itself, but rather
6816 a problem with the proprietary `make' programs.
6818 * doc/autoconf.texi (Build Directories): Add a cross reference
6821 * build-aux/config.guess, build-aux/config.sub, build-aux/texinfo.tex:
6822 * doc/standards.texi: Sync from gnulib.
6824 * man/autoconf.1, man/autoheader.1, man/autom4te.1, man/autoreconf.1:
6825 * man/autoscan.1, man/autoupdate.1, man/config.guess.1:
6826 * man/config.sub.1, man/ifnames.1: Remove from CVS, since they're
6827 generated automatically.
6829 2006-12-06 Paul Eggert <eggert@cs.ucla.edu>
6831 * lib/autoconf/c.m4 (_AC_PROG_CC_C89): Also try -xc99=all, for Sun
6832 C 5.8 on Solaris 10. Using -xc99=all rather than -xc99 bypasses
6833 the buggy -xc99 option of Forte Developer 7 C on Solaris 9.
6835 2006-12-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6837 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Drop the
6838 `CEOF$ac_eof' special marker, the awk script cannot contain a
6839 line matching `^CEOF', so this is not needed any more.
6840 * tests/torture.at (Substitute a newline): Expose the `%!_!# '
6841 special marker in the test.
6843 2006-12-06 Stepan Kasal <kasal@ucw.cz>
6845 * tests/tools.at (autom4te preselections): Use `find -newer';
6846 remove one of the sleeps.
6848 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE): Make it
6849 more readable, using ...
6850 (_AC_INIT_PARSE_ENABLE2): ... this new helper macro.
6852 * doc/autoconf.texi (autoheader Invocation): Do not double-
6853 quote the parameter of `AH_BOTTOM' in the example.
6855 2006-12-05 Stepan Kasal <kasal@ucw.cz>
6857 * doc/autoconf.texi (Configuration Headers): Remove the
6858 example with multiple input files.
6859 (autoheader Invocation): Encourage `AH_BOTTOM', discouraging
6860 multiple input files.
6862 2006-12-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6864 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): When
6865 creating the awk substitution script, handle one input line at a
6866 time, so that the maximum length of a substituted (multi-line)
6867 value is not limited by the size of the sed pattern space.
6868 The trade-off is a slightly repetitive sed script.
6869 * doc/autoconf.texi (Limitations of Usual Tools): Branch labels
6870 can only have up to 7 characters, due to Solaris 10 /bin/sed.
6871 * tests/torture.at (Substitute a 2000-byte string): Increase the
6872 test with several long lines, they should not be caught by sed
6875 * tests/tools.at (autom4te preselections): New test, to flag
6876 entries missing from autom4te.cfg.
6877 Report by David Byron <dbyron@hheld.com>.
6879 * tests/torture.at (Substitute a 2000-byte string): Actually use
6880 AC_PROG_AWK, so the last change works as intended.
6881 (Substitute and define special characters): Likewise.
6882 (Substitute a newline): Likewise.
6884 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Use `$AWK'
6885 instead of `awk' consistently.
6886 (_AC_OUTPUT_CONFIG_STATUS): Initialize $AWK.
6887 * tests/torture.at (Torturing config.status): Test both the
6888 result of AC_PROG_AWK and plain awk.
6889 (Substitute a 2000-byte string): Likewise.
6890 (Substitute and define special characters): Likewise.
6891 (Substitute a newline): Likewise.
6893 2006-12-04 Paul Eggert <eggert@cs.ucla.edu>
6895 * lib/autoconf/functions.m4 (AC_FUNC_FSEEKO): Check that fseeko
6896 can be assigned to a function pointer. Problem reported by
6897 Peter Palfrader in <http://bugs.debian.org/401377>. Based on
6898 part of a patch by Ralf Wildenhues in that same bug report.
6900 2006-12-01 Paul Eggert <eggert@cs.ucla.edu>
6902 * tests/mktests.sh (ac_exclude_list): Exclude AC_FUNC_SETVBUF_REVERSED.
6903 * tests/semantics.at (AC_FUNC_SETVBUF_REVERSED): New test.
6905 2006-12-01 Eric Blake <ebb9@byu.net>
6907 * lib/autoconf/c.m4 (AC_LANG_INT_SAVE): Avoid newline, to aid in
6908 cross-compiling from cygwin to mingw.
6909 Reported by Bob Rossi. This resurrects the 2000-11-30 patch to
6910 aclang.m4, which was mistakenly removed in the 2001-09-17 patch
6911 to lib/autoconf/c.m4.
6913 2006-12-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6915 * lib/m4sugar/m4sh.m4 (_AS_ECHO_PREPARE): Use a longer test
6916 string for more reliable failure. Wrap the entire test that
6917 causes the broken Solaris printf to dump core, in a subshell,
6918 so the segmentation fault message is reliably suppressed.
6919 Fix shell expansion errors by using /usr/ucb/echo always;
6920 avoid an error on systems without it by another subshell.
6921 Avoid m4 expansion of `$1'. Set the zeroth argument of the
6922 subshell-$as_echo to `as_echo', for better error message.
6924 2006-11-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6926 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): If `BASH_ARGV' or
6927 `BASH_SOURCE' contain a newline, set them to empty, as they may
6930 2006-11-27 Paul Eggert <eggert@cs.ucla.edu>
6932 Turn AC_FUNC_SETVBUF_REVERSED into a noop. It's been obsolete for
6933 years and is too hard to maintain now. The last straw was
6934 reported by Jerker Baeck in
6935 <http://lists.gnu.org/archive/html/autoconf/2006-11/msg00102.html>.
6936 * NEWS: AC_FUNC_SETVBUF_REVERSED is now obsolete.
6937 * doc/autoconf.texi (Particular Functions): Move
6938 AC_FUNC_SETVBUF_REVERSED from here...
6939 (Obsolete Macros): ... to here. Say that it does nothing now.
6940 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
6941 Turn into (almost) a no-op.
6943 * lib/autoconf/c.m4 (AC_PROG_GCC_TRADITIONAL, AC_C_CONST):
6945 Do not recommend via AN_FUNCTION, AN_IDENTIFIER, or AN_HEADER.
6946 These macros are obsolescent and new applications shouldn't need them.

6957 @VAR1@VAR2 has unspecified behavior. Problem reported by
6959 * NEWS: Mention this.
6961 * Makefile.am: Put only a single '#' into the copyright notice,
6962 so that it's also present in the output file. Standardize wording
6963 in makefile copyright notices to match GNU coding standards.

6977 2006-11-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6979 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Fix error
6980 in the sed script that mangles the awk script: delete up to the
6981 first exclamation mark only.
6982 * tests/torture.at (Substitute and define special characters):
6985 2006-11-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6987 Rewrite config files generation: avoid quadratic growth in
6988 the number of substituted variables by using awk instead of sed
6989 for the bulk of the substitutions.
6990 * NEWS: Mention this.
6991 * doc/autoconf.texi (Setting Output Variables): `|#_!!_#|' is also
6992 forbidden in the output (and thus input) file.
6993 * lib/autoconf/status.m4 (_AC_AWK_LITERAL_LIMIT): New macro.
6994 (_AC_OUTPUT_FILES_PREPARE): Instead of several sed scripts,
6995 generate just one large awk script for substitutions,
6996 eliminating much of the earlier complexity, while adding some
6997 new complexity. Only expand the substitution templates at
6998 configure time, for smaller configure script size. If
6999 _AC_SUBST_FILES are used, test 'awk' for working getline support
7000 at config.status time. If absent, interpolate through the
7001 shell. The awk script was written with much help
7002 from Paolo Bonzini and Paul Eggert.
7003 (_AC_SED_CMD_NUM, _AC_SED_DELIM_NUM, _AC_SED_FRAG): Removed.
7004 (_AC_SED_FRAG_NUM): Likewise.

7007 (_AC_OUTPUT_FILE): Use _AC_SUBST_CMDS.
7008 * tests/torture.at (Substitute a 2000-byte string): Also
7009 substitute a line with 1000 words, and a variable with several
7011 (Substitute and define special characters): Test awk special
7012 characters, and put substitution input strings `@foo@' in the
7013 output, to test that no recursion happens; test several other
7014 combinations from Paolo Bonzini.
7016 2006-11-25 Paul Eggert <eggert@cs.ucla.edu>
7018 * lib/autotest/general.m4 (AT_INIT): Undo recent changes
7019 that replaced echo with AS_ECHO where this wasn't necessary.
7020 Problem reportd by Ralf Wildenhues.
7021 * lib/m4sugar/m4sh.m4 (_AS_ECHO_PREPARE): Port to Solaris 7,
7022 where "/usr/bin/printf '%s\n' S" dumps core if S is long.
7023 This is Sun bug 4206210. Problem reportd by Ralf Wildenhues.
7025 2006-11-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7027 * lib/freeze.mk (GREP): Removed, no need to initialize this.
7029 2006-11-21 Paul Eggert <eggert@cs.ucla.edu>
7031 * doc/autoconf.texi (Limitations of Usual Tools): Don't claim
7032 that traditional Awk lacks 3-arg "split". It has it.
7033 Mention that FS must be a single character, and a few other
7034 99-byte limits of traditional Awk.
7035 Mention that if (i in a) doesn't work with traditional Awk.

7041 (Newline-CODE-BS-newline in command):
7042 (Single-quote-BS-newline in command):
7043 (Single-quote-newline-BS-newline in command):
7044 Use printf '%s\n' instead of echo, for portability to hosts
7045 where echo interprets backslashes. This will break on hosts
7046 that lack printf, but for now let's assume all such hosts
7047 are dead (if not, we should get reports of test failures).
7049 2006-11-17 Paul Eggert <eggert@cs.ucla.edu>
7051 'echo' has some portability problems, when given a first argument
7052 with a leading '-', or when given any argument containing '\'.
7053 Avoid using 'echo' in these cases.
7054 * bin/Makefile.am $(bin_SCRIPTS): Rewrite to avoid 'echo' entirely.

7082 * lib/autoconf/general.m4 (AC_MSG_RESULT, AC_MSG_RESULT_UNQUOTED):
7083 Don't use ECHO_T, since ECHO_N is now reliable.
7084 * lib/autotest/general.m4 (AT_INIT): Likewise.
7085 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Use sed "$script"
7086 rather than using a here-document to put the script into a file.
7087 (_AC_DO_ECHO): Hoist the eval out of the echo, so that we can
7089 * lib/m4sugar/m4sh.m4 (AS_VAR_GET): Likewise.
7090 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Use
7091 AS_ECHO_N rather than ECHO_N and ECHO_C. This doesn't fix any
7092 bug, but we might as well stop using ECHO_N and ECHO_C internally.

7095 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):

7097 operand, as AS_ECHO requires. Avoid double file name expansion.
7098 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Invoke _AS_ECHO_PREPARE.
7099 Don't set as_nl, since _AS_ECHO_PREPARE does that now.
7100 (_AS_PREPARE): Comment that _AS_ECHO_N_PREPARE is just for user code.
7101 (AS_ECHO, AS_ECHO_N, _AS_ECHO_PREPARE): New macros.
7102 * tests/c.at (AC_PROG_CPP without warnings, AC_PROG_CPP via CC):
7103 Double-quote strings that would otherwise contain M4 comments.
7104 * tests/m4sh.at (AS_ECHO and AS_ECHO_N): New test.
7106 * configure.ac (AC_INIT): Bump to 2.61a.
7109 2006-11-17 Paul Eggert <eggert@cs.ucla.edu>
7113 * configure.ac (AC_INIT): Bump to 2.61.
7116 * tests/autotest.at (Macro with backslash in a test title):
7117 Comment out for now, as this tests neither fails nor passes
7118 reliably. Problem reported by Ralf Wildenhues.
7120 2006-11-16 Paul Eggert <eggert@cs.ucla.edu>
7122 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE): Fix some typos
7123 in previous change, which caused test failures.

7233 and Stepan Kasal <kasal@ucw.cz>
7235 Handle special characters in test case titles correctly.
7236 * lib/autotest/general.m4 (AT_INIT): M4-quote and AS_ESCAPE AT_help_all
7238 (AT_SETUP): M4-quote and AS_ESCAPE the title properly everywhere.
7239 * tests/autotest.at (AT_CHECK_AT_TITLE): Add EXPANDED-TITLE-TO-TEST
7240 argument. Extend to check titles printed by ./micro-suite and
7241 ./micro-suite -l and the title in micro-suite.log.
7242 (Backquote in a test title,
7243 Single-quote in a test title,
7244 Double-quote in a test title): Don't expect failure anymore.
7245 (Backslash in a test title): Put a non-whitespace character after the
7246 backslash so that Bourne shells might actually see it as an escape
7248 (Brackets in a test title,
7249 Pound in a test title,
7250 Comma in a test title,

7266 2006-10-26 Paul Eggert <eggert@cs.ucla.edu>
7268 * tests/base.at (AC_COMPUTE_INT): Test **0** rather than 1 / 0,
7269 since powerpc-apple-darwin8-gcc-4.0.1 (Apple Computer, Inc. build
7270 5363) simply issues a warning when dividing by zero at compile
7271 time. Problem reported by Elias Pipping.
7273 2006-10-26 Eric Blake <ebb9@byu.net>
7276 * doc/autoconf.texi (Evaluation Macros): Improve the example to
7277 show effect on macros that expand with commas.

7304 * lib/autoconf/specific.m4 (_AC_SYS_LARGEFILE_MACRO_VALUE):
7305 If FUNCTION-BODY is nonempty, use AC_LINK_IFELSE rather than
7306 AC_COMPILE_IFELSE, to work around problem with OSF/1 4.0F fseeko
7307 reported by Nelson H. F. Beebe for Coreutils 6.4.
7309 * tests/tools.at (autoconf --trace: user macros): Remove test
7310 for tracing multiline macros, since m4 1.4.7a uses a different
7311 way to number lines. Problem reported by Ralf Wildenhues.

7373 looking for special shell characters.

7387 2006-10-14 Paul Eggert <eggert@cs.ucla.edu>
7389 (Imported from Automake.)
7390 * build-aux/install-sh (posix_mkdir): Reject FreeBSD 6.1 mkdir -p -m,
7391 which incorrectly sets the mode of an existing destination
7392 directory. In some cases the unpatched install-sh could do the
7393 equivalent of "chmod 777 /" or "chmod 0 /" on a buggy FreeBSD
7394 system. We hope this is rare in practice, but it's clearly worth
7395 fixing. Problem reported by Alex Unleashed in
7396 <http://lists.gnu.org/archive/html/bug-autoconf/2006-10/msg00012.html>.
7397 Also, don't bother to check for -m bugs unless we're using -m;
7398 suggested by Stepan Kasal.

7452 include the default headers, and redefine obstack_chunk_alloc
7453 and obstack_chunk_free. Fixes false failure with glibc.

7475 (AS_EXECUTABLE_P): Use as_test_x rather than as_executable_p.
7476 (_AS_TEST_PREPARE): Set as_test_x rather than as_executable_p.
7477 Use a better substitute, by inspecting the output of "ls"
7478 rather than just using ":".
7479 * lib/autoconf/general.m4 (_AC_LINK_IFELSE): Use AS_TEST_X
7480 rather than AS_EXECUTABLE_P, since we needn't worry about
7481 non-regular files here.
7483 * NEWS: Autoconf-generated shell scripts no longer export BIN_SH,
7484 due to configuration hassles with this. See Tonya Underwood's report

7496 * lib/m4sugar/m4sh.m4 (AS_BOURNE_COMPATIBLE): Move the
7497 initialization which is not inherited through the environment
7498 (_AS_BOURNE_COMPATIBLE): ... to this new macro.
7499 (_AS_RUN): Call _AS_BOURNE_COMPATIBLE, not AS_BOURNE_COMPATIBLE.

7506 2006-10-06 Paul Eggert <eggert@cs.ucla.edu>
7508 * lib/autoconf/c.m4 (_AC_PROG_PREPROC_WORKS_IFELSE): Remove
7509 comment about ac_cpp_err; it was incorrect, and anyway
7510 ac_cpp_err is being removed below.
7511 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE): Don't
7512 set ac_cpp_err to 'yesyes' if preproc_warn_flag and werror_flag
7513 are both 'yes'. In fact, don't bother setting ac_cpp_err at all;
7515 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't log our funky tests
7516 with werror_flag and conftest.err and so forth. This is more
7517 compatible with how _AC_PROG_PREPROC_WORKS_IFELSE behaves,
7518 and anyway the user shouldn't normally want to see this gorp logged.
7519 Problem reported by Ralf Wildenhues.
7520 * lib/autoconf/lang.m4 (AC_LANG_WERROR): werror_flag's default is
7521 empty, not 'no', since the rest of the code uses 'test -z'.
7523 2006-10-04 Paul Eggert <eggert@cs.ucla.edu>
7525 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE):
7526 Use a single call to AC_DO_TOKENS rather than multiple, for
7528 (_AC_LINK_IFELSE): Test that resulting file is executable.
7529 Problem reported by mwoehlke in
7530 <http://lists.gnu.org/archive/html/bug-coreutils/2006-10/msg00048.html>.
7532 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Use "test -x /" rather
7533 than creating a file to use with test -x; this is much faster.
7535 2006-10-02 Bruno Haible <bruno@clisp.org>
7537 * lib/autom4te.in (Automake-preselections): Add
7538 AM_GNU_GETTEXT_INTL_SUBDIR, for automake 1.10.
7540 2006-09-27 Stepan Kasal <kasal@ucw.cz>
7542 * doc/autoconf.texi (Writing testsuite.at): Fix a typo: for
7543 standard error, `experr' should be used, not `expout'.

7547 * lib/autoconf/functions.m4 (AC_FUNC_FSEEKO): Don't compile the
7548 fseeko testing program twice; just use the earlier result.
7549 * lib/autoconf/specific.m4 (_AC_SYS_LARGEFILE_MACRO_VALUE):
7550 Set cache var to 'unknown' (not 'no') if leaving the macro unset
7551 still doesn't let the program compile.
7552 (AC_SYS_LARGEFILE): Test for _LARGE_FILES only if earlier tests
7555 * lib/autoconf/functions.m4: Fix problems reported by Ralf Wildenhues.
7556 (AC_FUNC_ERROR_AT_LINE): Don't bother to check for error.h. Just
7557 include it, without including anything else.
7558 (AC_FUNC_FSEEKO): Avoid gcc -Wall warnings about constant
7560 (AC_FUNC_STRNLEN): Require AC_USE_SYSTEM_EXTENSIONS.

7564 * lib/autoconf/functions.m4 (AC_FUNC_ERROR_AT_LINE): Check for
7565 `error.h', and include it, for a `error_at_line' prototype.
7566 Use a nonempty format string in the link test.
7567 * lib/autoconf/functions.m4 (AC_FUNC_WAIT3): Include <sys/wait.h>,
7568 for a declaration of wait3.

7574 can apply to constants too, and that it checks for macro defns.
7575 * lib/autoconf/general.m4 (AC_CHECK_DECL): Assume C89 or better,

7577 values. Problem reported by Ralf Wildenhues.

7792 broken lex libraries like native ia64-hp-hpux11.22; see
7793 <http://sources.redhat.com/ml/binutils/2003-12/msg00337.html>, and

7921 * NEWS: Autoconf now uses constructs like "#ifdef HAVE_STDLIB_H"
7922 rather than "#if HAVE_STDLIB_H", so that it now works with "gcc
7923 -Wundef -Werror". Problem reported by David Fang in
7924 <http://lists.gnu.org/archive/html/autoconf/2006-08/msg00045.html>.

7947 problems with arg script text that doesn't end in newline, and

7984 less skeptical about "volatile", after discussion with
7985 Bruno Haible on bug-gnulib.
7986 (Limitations of Usual Tools): Warn about sed stripping
7987 leading white space from text. From Bruno Haible.
7989 2006-07-20 Paul Eggert <eggert@cs.ucla.edu>
7991 * lib/autoconf/libs.m4 (AC_PATH_XTRA): Don't use -R if the
7992 compiler complains about it, even if things works after the
7993 complaint. Problem reported by Peter O'Gorman.

7996 CPPFLAGS, and LDFLAGS better. Problem reported by Bruno Haible.

7999 2006-07-17 Paul Eggert <eggert@cs.ucla.edu>
8001 * lib/autoconf/libs.m4 (AC_PATH_XTRA): Do the check for space
8002 after -R regardless of host. Patrick Welche reports that this

8013 * doc/autoconf.texi (C Compiler): Add a ref to Volatile Objects
8014 under AC_C_VOLATILE.
8015 (Volatile Objects): Be a little less skeptical about what
8016 "volatile" means. Derived from thoughts by Ben Pfaff in
8017 <http://lists.gnu.org/archive/html/bug-gnulib/2006-07/msg00092.html>.
8019 2006-07-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

8023 2006-07-07 Paul Eggert <eggert@cs.ucla.edu>
8025 * tests/torture.at (Configuring subdirectories): Set CONFIG_SITE
8026 more globally, since the 2006-06-30 patch didn't suffice. Problem
8027 reported by Keith Marshall. Also, don't bother with builddir2,
8028 since it shouldn't be needed any more.
8030 2006-07-07 Paolo Bonzini <bonzini@gnu.org>
8032 * doc/autoconf.texi (Generic compiler characteristics):
8033 Document AC_COMPUTE_INT. Fix wrong statements on Default

8049 2006-07-02 Paul Eggert <eggert@cs.ucla.edu>
8051 * lib/autoconf/types.m4 (AC_TYPE_LONG_LONG_INT):
8052 Require that long long int be at least 64 bits wide. C99 requires
8053 this and enough programs depend on it so we should check for it.
8054 Bruno Haible reports in
8055 <http://lists.gnu.org/archive/html/bug-gnulib/2006-06/msg00286.html>
8056 that long long int is 32 bits wide with some nonstandard compilers.
8057 (AC_TYPE_UNSIGNED_LONG_LONG_INT): Likewise.
8059 2006-06-30 Paul Eggert <eggert@cs.ucla.edu>
8061 * tests/torture.at (Configuring subdirectories): Set CONFIG_SITE
8062 to a nonexistent file, so that we don't have to worry about
8063 a local site configuration that doesn't use /usr/local.
8064 Problem reported by Keith Marshall in
8065 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00133.html>.
8067 2006-06-28 Paul Eggert <eggert@cs.ucla.edu>
8069 * doc/autoconf.texi: Be more consistent about using @acronym with
8070 "HP" and "HP-UX". Remove mention of OSF; the old version wasn't
8071 quite right (it talked about "OSF/Tru64", even though the
8072 operating systems were called OSF/1, Digital UNIX, and Tru64 UNIX,
8073 and it even mentioned "OSF 4"!) and at this point there's little
8074 reason to talk about OSF any more, since it died in 1994.
8075 (Specific Compiler Characteristics): Simplify example of
8076 negative-size array.
8077 (File Descriptors): Reorder to make the text flow better.
8078 Remove joke about "appreciate the various levels"; I didn't get it.
8079 Add remark about HP-UX sh -x bug with stderr noted by Bob Proulx in
8080 <http://lists.gnu.org/archive/html/bug-coreutils/2006-06/msg00225.html>.
8081 (File Descriptors, Limitations of Usual Tools):
8082 Tone down the advice against renaming or removing open files.
8083 (Limitations of Usual Tools): Add a new section, on 'rm'.
8085 2006-06-26 Stepan Kasal <kasal@ucw.cz>
8087 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Use -lX11, not
8088 -lXt in LIBS, idea from Karsten Hopp; this was due since
8091 2005-09-18 Paul Eggert <eggert@cs.ucla.edu>
8092 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Look for X11/Xlib.h
8093 and XrmInitialize rather than X11/Intrinsic.h and XtMalloc
8094 (which belong to Xt, not X itself). See Debian bug 327655.
8096 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8098 * configure.ac (AC_INIT): Bump to 2.60a.

8111 * bin/autom4te.in (handle_traces): Transform the `@S|@'
8112 quadrigraph correctly in traces.
8114 * NEWS, lib/Autom4te/C4che.pm, lib/autoconf/functions.m4:

8118 datarootdir-related errors only if AC_DATAROOTDIR_CHECKED is
8120 * doc/autoconf.texi (Changed Directory Variables): New node,
8121 to document the whole `datarootdir' business a bit better.
8123 * tests/torture.at (datarootdir workaround): Extend test.
8124 Prompted by report by Alexandre Julliard.
8126 2006-06-22 Paul Eggert <eggert@cs.ucla.edu>
8128 * lib/autoconf/c.m4 (_AC_PROG_CC_C89): Check for C89 incompatibility
8129 when using default mode of IBM C 6 for AIX. Problem and two-line
8130 fix reported by Larry Jones.
8132 2006-06-22 Alexandre Julliard <julliard@winehq.org>
8134 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Avoid warning
8135 about literal '${datarootdir}' if a definition is found in the
8138 2006-06-20 Paul Eggert <eggert@cs.ucla.edu>
8140 * NEWS: Use "M4" rather than "m4" when appropriate.
8141 Problem reported by Eric Blake.
8142 * doc/autoconf.texi: Likewise.
8143 Use @acronym around BSD, GCC, and GNU when appropriate.
8144 (Why GNU M4): Renamed from "Why GNU m4".
8145 (Redefined M4 Macros): Mention that Posix
8146 m4wrap takes only 1 argument, but GNU M4 1.4.x takes more.
8147 (Buffer Overruns): Mention size_t and ptrdiff_t as alternatives
8150 2006-06-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8152 * bin/autom4te.in (handle_output): Do not forbid the empty
8154 * tests/tools.at (autoconf: the empty token): New test.
8156 2006-06-20 Stepan Kasal <kasal@ucw.cz>
8158 * lib/m4sugar/m4sugar.m4 (m4_init): Merge the two m4_wrap
8159 calls, so that we do not care whether they are LIFO or FIFO;
8160 in the m4_wrap, do not check which diversion is the topmost
8161 one, just check that the stack is balanced at the end.
8162 * lib/m4sugar/m4sh.m4 (AS_INIT): We are going to change the
8163 base diversion forever--pop the previous diversion before
8164 opening the new one; consequently, remove the m4_wrap call.
8165 * lib/autotest/general.m4 (AT_INIT): Likewise.
8166 * tests/m4sugar.at: Do not use
8167 m4_wrap([m4_diversion_pop([..])]), for educational purposes.

8170 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8172 * NEWS: Document that m4wrap/m4_wrap might not be LIFO.
8173 * doc/autoconf.texi (Redefined M4 Macros): Likewise.
8174 Rework example of m4wrap token-pasting trouble so that it doesn't
8175 care whether it's LIFO or FIFO.
8176 Fix some "contrary to"s that are awkward in English.
8178 2006-06-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8180 * lib/autoconf/types.m4 (_AC_TYPE_INT): Set `$ac_cv_c_int$1_t'
8181 to `yes' instead of `int$1_t' if the type is found, for more
8182 consistent configure output (where $1 is the number of bits).
8183 (_AC_TYPE_UINT): Likewise for `uint$1_t'.
8184 Suggested by Bruno Haible.
8186 * lib/autoconf/types.m4 (_AC_TYPE_UNSIGNED_INT): Solaris 2.5.1
8187 needs _UINT8_T and _UINT64_T defines as well, to avoid clashes
8188 with system headers. Report by Bruno Haible.
8190 2006-06-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8192 * config/config.guess, config/config.sub: Sync from upstream.
8194 * bin/Makefile.am (autoconf.in): Use `--melt' for autom4te,
8195 in order to avoid picking up an older installed frozen m4sh.m4f.
8196 Besides an outdated shell startup, this could have been created
8197 by an earlier M4 version with incompatible frozen file format.
8199 2006-06-16 Paul Eggert <eggert@cs.ucla.edu>
8201 * README: Recommend m4 1.4.4 instead of 1.4.3..
8202 * doc/autoconf.texi: Likewise.
8203 (Special Chars in Names): Say that $(.FOO) is portable, as
8204 suggested by Stepan Kasal.
8205 (Installation Directory Variables, Build Directories):
8206 (Automatic Remaking, Subdirectories, Fortran Compiler):
8207 (Making testsuite Scripts, Defining Directories):
8208 Quote variable usages better.
8209 (Making testsuite Scripts): Add clean-local rule to makefile
8210 snippet, by Eric Blake.
8211 (Installation Directory Variables): Fix table item font.
8212 Reword slightly to clarify. Generalize advice about
8213 not using special characters to include all file-related
8214 vars, not just VPATH.
8215 (Special Chars in Variables): Warn about special characters in
8217 (Assignments): Clarify default-value example as suggested by
8219 <http://lists.gnu.org/archive/html/autoconf-patches/2006-06/msg00072.html>.
8220 (Special Shell Variables): Note leading ./ or ../, as suggested
8222 (Limitations of Builtins): Under cd, warn about CDPATH.
8223 (The Make Macro MAKEFLAGS): Untabify. Problem reported by
8226 2006-06-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8228 * doc/autoconf.texi (Configuration Actions): Remove duplicate
8229 `@var', for texi2html.
8230 (Systemology): Some more word wrapping, for DVI output.
8231 (autom4te Invocation): The short option for `--melt' is `-M',
8234 2006-06-15 Paul Eggert <eggert@cs.ucla.edu>
8236 * doc/autoconf.texi: More formatting and English tweaks,
8237 many suggested by Ralf Wildenhues.
8238 Reword to avoid "@code{...}'s" and the like, since it's ugly
8239 with Emacs info mode. discontents -> woes.
8240 Put a few "will"s back. time stamp -> timestamp.
8241 side-effect -> side effect.
8243 2006-06-14 Paul Eggert <eggert@cs.ucla.edu>
8245 * doc/autoconf.texi (Initializing configure, Shell Substitutions):
8246 Warn about $@ not persisting. Problem reported by Julien Danjou in
8247 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=372179>.
8248 (Special Chars in Names): Renamed from Leading _ in Macro Names.
8249 Mention other special chars, too.
8251 2006-06-14 Eric Blake <ebb9@byu.net>
8253 * doc/autoconf.texi (The Make Macro MAKEFLAGS): New node.
8255 2006-06-13 Paul Eggert <eggert@cs.ucla.edu>
8257 * doc/autoconf.texi: Some systematic minor improvements, as
8258 follows. Use "makefile" when talking about makefiles
8259 generally (which might be named "makefile" or "Makefile" or even
8260 "foo.mk"), "Makefile" when talking about a specific makefile
8261 called "Makefile". This unclutters the text from weird quotes
8262 (e.g., "`Makefile's" in info mode). Similarly, use "@var{foo}
8263 values" rather than "@var{foo}s" and similar constructs containing
8264 "}s". Use "Make rules" rather than "Makefile rules". Minor
8265 English-language improvements. Change the prefix "sub-" to "sub"
8267 Put blank lines around examples more consistently.
8268 Avoid "rather" and "very" as intensifiers.
8269 Avoid "will" as an auxiliary.
8270 (Limitations of Make): Split this node into....
8271 (Portable Make, $< in Ordinary Make Rules, Failure in Make Rules):
8272 (Leading _ in Macro Names, Backslash-Newline-Newline):
8273 (Backslash-Newline Comments, Long Lines in Makefiles):
8274 (Macros and Submakes, The Make Macro SHELL, Comments in Make Rules):
8275 (obj/ and Make, make -k Status, VPATH and Make):
8276 (VPATH and Double-colon, $< in Explicit Rules):
8277 (Automatic Rule Rewriting, OSF/Tru64 Directory Magic):
8278 (Make Target Lookup, Single Suffix Rules, Timestamps and Make):
8279 New nodes, resulting from splitup of Limitations of Make.
8280 All cross-references changed. Raise the top node from
8281 a section to a chapter, and all subnodes accordingly.
8282 Redo the introductory wording to match the new organization.
8283 (Installation Directory Variables): Use an example that is
8284 closer to what Autoconf actually does. Mention that VPATH's
8285 value should not contain metacharacters or white space.
8286 (Fortran Compiler): Fix a VPATH bug in an example.
8287 (Leading _ in Macro Names): Mention that this problem is no longer
8288 of practical concern.
8289 (VPATH and Make): Reword the advice to make it clearer
8290 that Autoconf and Automake support VPATH in non-GNU make, but
8291 many packages have bugs in this area.
8292 ($< in Explicit Rules): Refer to Build Directories rather
8293 than using a (non-VPATH-safe) example.
8294 (Automatic Rule Rewriting): Mention the sort of disaster that
8295 can ensue with Solaris-style rule rewriting with VPATH.
8297 2006-06-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8299 * doc/install.texi (Compilers and Options): Weaken the
8300 suggestion to use GNU make for VPATH builds.
8302 * lib/autom4te.in (Automake-preselections): Add AM_PROG_CXX_C_O,
8303 AM_PROG_F77_C_O, AM_PROG_FC_C_O, AC_FC_SRCEXT, AC_FC_FREEFORM.
8305 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Fix M4 quotation
8306 in regular expression.

8310 * doc/autoconf.texi (Installation Directory Variables):
8311 Drop extra @samp from `@table @samp' item.
8312 (Limitations of Usual Tools): Comment fix.
8313 Do not nest @samp just to point to other table items.
8314 (Writing testsuite.at) <AT_CHECK>: The second argument to
8315 `@dvar' is already @samp'ed.
8316 (Making testsuite Scripts) <AC_CONFIG_TESTDIR>: Likewise,
8317 do not use @var in the second argument.
8319 2006-06-07 Paul Eggert <eggert@cs.ucla.edu>
8321 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Look for
8322 $as_shell.exe too. Problem reported by Andreas Buening in
8323 <http://lists.gnu.org/archive/html/autoconf/2006-06/msg00038.html>.
8325 2006-06-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8327 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA): Work around
8328 `unused variable' compiler warning, for `-Wall -Werror'.
8329 Reported by Jaap Haitsma in
8330 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00012.html>.
8332 2006-06-06 Paul Eggert <eggert@cs.ucla.edu>
8334 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Remove core file, in
8335 case the compiler dumps core. Problem reported for
8336 OpenServer 5.0.7 by Tim Rice in
8337 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00019.html>.

8341 2006-06-06 Tim Rice <tim@multitalents.net>.
8343 * lib/freeze.mk: Quiet check-forbidden-patterns so the string
8344 "ERROR" only shows up in "make check" output if there is an

8368 * config/texinfo.tex: Sync from upstream.
8370 * bin/autoreconf.in: Trace `LT_CONFIG_LTDL_DIR'; if it has been
8371 seen, invoke libtoolize with `--ltdl' argument.
8372 * lib/autom4te.in (Autoreconf-preselections): Adjust.
8374 Suggested by Eric Blake.
8376 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>

8388 * doc/autoconf.texi: Modernize some of the references to Solaris.
8390 2006-06-05 Stepan Kasal <kasal@ucw.cz>
8392 * lib/m4sugar/m4sugar.m4 (m4_require): Modify the error
8393 message issued by AC_REQUIRE.
8394 * tests/m4sugar.at: Check m4_require's error message.
8395 * tests/base.at: Check AC_REQUIRE's error message.
8396 * tests/local.at (AT_CHECK_M4): New macro, almost identical
8398 (AT_CHECK_AUTOM4TE): ... which is now a thin wrapper around
8400 (AT_CHECK_AUTOCONF): Use AT_CHECK_M4; no longer support
8401 `expout' as the last parameter.
8402 * tests/tools.at: Adapt to the above change.
8404 2006-06-04 Stepan Kasal <kasal@ucw.cz>
8406 * doc/autoconf.texi (Limitations of Usual Tools): Correct
8407 information about race-free implementations of mkdir.

8416 2006-06-04 Paul Eggert <eggert@cs.ucla.edu>
8418 * NEWS: GNU make now recommended for VPATH builds.
8419 Mention that some macros are now documented to be obsolescent.
8420 * doc/autoconf.texi:
8421 Prefer "current" to "modern" to describe
8422 currently-used (albeit perhaps old-fashioned) hosts.
8423 Mention which ancient features no longer need to be worried about.
8424 setgid -> set-group-ID
8425 setuid -> set-user-ID (these are the Posix terms)
8426 Fix some misuses of "only".
8427 (AC_C_BACKSLASH_A, AC_C_CONST, AC_C_PROTOTYPES):
8428 (AC_C_STRINGIZE, AC_C_VOLATILE, AC_FUNC_CLOSEDIR_VOID):

8436 Mention that these macros are obsolescent.
8437 (Installation Directory Variables): shall -> should
8438 (File Descriptors): Mention that 0, 1, 2 might get reopened.
8439 Mention that it's now safe to use 3 and 4.
8440 (Limitations of Usual Tools): cp -r is now specified by Posix.
8441 Omit longwinded and obsolescent discussion of cp -f.
8442 Modernize discussion of expr, ls.
8443 (Limitations of Make): Modernize discussion of VPATH builds.
8444 Mention $? as a workaround in some cases.
8445 * doc/install.texi (Basic Installation):
8446 Mention "./configure; make; make install" first. Be more
8447 specific about why this file is generic. Remove unnecessary
8448 parens. Remove misleading "only". Remove obsolete advice
8449 about csh. Don't say "configure" takes awhile; say it
8450 might take a while. Suggest CFLAGS=-g rather than CFLAGS=-O2,
8451 and CC=c99 rather than CC=c89, as these are blessed by current
8452 Posix. Recommend GNU make if doing a VPATH build.
8454 2006-06-03 Paul Eggert <eggert@cs.ucla.edu>
8456 * doc/autoconf.texi: Use a consistent style "$ @kbd{...}" for
8457 examples involving shell prompts.
8459 2006-06-02 Stepan Kasal <kasal@ucw.cz>
8460 and Paul Eggert <eggert@cs.ucla.edu>
8462 * doc/autoconf.texi (Here-Documents): Add details about the
8463 pre-ksh93g bug. Reword slightly to make it clearer. Consistently
8464 use "here-documents" instead of "here documents".
8466 2006-06-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8468 * config/texinfo.tex, doc/standards.texi: Sync from upstream.

8472 * doc/autoconf.texi (File System Conventions): Warn about ":"
8473 anywhere in directory names.
8475 2006-05-31 Paul Eggert <eggert@cs.ucla.edu>
8477 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be even more conservative
8478 about quoting the case statement, just in case.
8479 * doc/autoconf.texi (Here-Documents): Mention that the ksh bug
8480 was fixed in ksh93g; reported by Ralf Wildenhues.
8482 2006-05-31 Stepan Kasal <kasal@ucw.cz>
8484 * doc/autoconf.texi (System Services): Do not document

8493 * lib/m4sugar/m4sh.m4 (_AS_DIRNAME_PREPARE): Guard against test
8494 argument with leading hyphen. Problem reported by Paul Eggert.
8496 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
8498 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be more conservative
8499 about quoting ac_try: quote all of it, if any of it seems suspicious.
8500 This means we don't have to worry about ${ or sed any more.
8501 Also, double-quote the case statement, to work around misuses via
8502 underquoting as reported by Ralf Wildenhues in
8503 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00169.html>.
8504 (_AC_EVAL_STDERR): Revert, since evidently some packages rely on this
8505 undocumented and dangerous macro.

8517 * lib/autoconf/general.m4: Revert AC_TRY_EVAL and AC_TRY_COMMAND,
8518 since evidently some packages rely on the old, broken behavior.
8519 Problem reported by Ralf Wildenhues in
8520 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00160.html>.
8521 (AC_TRY_EVAL, AC_TRY_COMMAND, _AC_EVAL): Go back to the
8522 pre-2006-05-26 definitions, but leave in the comments that
8523 these macros are dangerous and should not be used.
8524 (_AC_DO_ECHO): Renamed from _AC_EVAL_ECHO. All callers changed.
8525 (_AC_DO): Renamed from _AC_EVAL. All callers changed.
8526 (_AC_DO_STDERR): Renamed from _AC_EVAL_STDERR. All callers changed.
8527 (_AC_DO_VAR): Renamed from AC_TRY_EVAL.
8528 (_AC_DO_TOKENS): Renamed from AC_TRY_COMMAND.
8530 2006-05-29 Paul Eggert <eggert@cs.ucla.edu>
8532 * lib/autoconf/status.m4 (AC_OUTPUT_MAKE_DEFS): Rewrite to avoid
8533 the use of 'tr', since this is our only use of 'tr'.
8535 2006-05-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8536 and Paul Eggert <eggert@cs.ucla.edu>
8538 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE):
8539 Don't assume 'grep' works on long lines, since AIX grep doesn't.
8541 2005-05-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8543 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Do not use `grep' on
8544 the output file in the `${datarootdir}' test.
8546 2005-05-28 Stepan Kasal <kasal@ucw.cz>
8547 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8549 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If we have not seen
8550 mention of `datarootdir' in the input file(s), but literal
8551 `${datarootdir}' in the output file, and we haven't warned yet,
8552 then warn as well: the user may have (erroneously) used
8553 `AC_SUBST([mydatadir], [$datadir/my])' instead of the correct
8554 `AC_SUBST([mydatadir], ['${datadir}/my'])'.
8555 * tests/torture.at (datarootdir workaround): Extend this test.

8559 and Paul Eggert <eggert@cs.ucla.edu>
8561 * doc/autoconf.texi (autoheader Invocation): The first argument to
8562 `AC_DEFINE_UNQUOTED' need not be a literal. Mention the
8563 alternatives and clear up the language a bit.
8565 2006-05-27 Paul Eggert <eggert@cs.ucla.edu>
8567 * NEWS: Reword notice for AC_TRY_COMMAND, AC_TRY_EVAL,
8568 ac_config_guess, ac_config_sub, ac_configure.
8569 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
8570 Fix typo that prevented an unnecessary space from being removed.
8571 Problems reported by Ralf Wildenhues in:
8572 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00143.html
8574 2006-05-26 Paul Eggert <eggert@cs.ucla.edu>
8576 * doc/autoconf.texi (Particular Programs, Limitations of Usual Tools):
8577 Use better wording to talk about AC_PROG_MKDIR_P's thread-safety.
8578 Don't use the term "thread-safe" to talk about mkdir race
8579 conditions, since the problem is more a process than a thread
8580 issue. Problem reported by Stepan Kasal in:
8581 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00088.html
8582 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Use code that mimics
8583 the test for 'install' more closely. Look at MKDIR_P first.
8584 Look in the PATH, and at /opt/sfw/bin.
8585 Look for a 'gmkdir' program as well (Solaris 10 /opt/sfw/bin/gmkdir).
8586 Don't bother to try mkdir -p, since we already check mkdir --version;
8587 just look at the version number. (There's no easy way to check
8588 for race-free implementations.)
8589 * tests/tools.at (autoconf: subdirectories): Adjust to above
8590 changes, since MKDIR_P now might end in "/mkdir -p".
8592 * doc/autoconf.texi (autoheader Invocation): Mention that the
8593 first arg of AC_DEFINE_UNQUOTED must be a literal.
8594 Problem reported by Ben Pfaff in
8595 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00090.html>.
8597 * NEWS: Mention that AC_TRY_COMMAND and AC_TRY_EVAL may be removed.
8598 * doc/autoconf.texi (Special Chars in Variables): New section.
8599 (Preset Output Variables): Warn about special chars in CPPFLAGS.
8600 (Installation Directory Variables): Quote $(datadir) better.
8601 (Limitations of Builtins): Describe some of eval's trickiness.
8603 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Simplify quoting.
8604 * lib/autoconf/fortram.m4 (_AC_PROG_FC_V_OUTPUT): Likewise.
8605 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Put leading space
8606 in front of every arg, not just trailing args. Quote apostrophes.
8607 (_AC_EVAL_ECHO): New macro.
8608 (_AC_EVAL, AC_EVAL_STDERR): Use it. Quote arg of eval.
8609 (AC_TRY_EVAL, AC_TRY_COMMAND): Mention that these macros might get
8611 (_AC_LINK_IFELSE): Use proper rule for shell continuation lines,
8612 exposed by quoting of eval argument. Put the command on line line
8614 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): Use eval more safely.
8615 (_AC_PATH_X, AC_PATH_X): Quote more safely.
8616 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Use eval more safely.
8617 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Don't use eval.
8618 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Minor style change.
8619 Handle special chars in prefix, ac_srcdir, ac_aux_dir.
8620 Use eval more safely.
8621 (_AC_OUTPUT_CONFIG_STATUS): Adjust to above changes.
8622 * lib/m4sugar/m4sh.m4 (AS_VAR_GET): Note that this API needs
8624 * tests/base.at (AC_TRY_COMMAND): Use proper rule for shell continuation
8625 lines, exposed by quoting of eval argument.
8627 2006-05-26 Stepan Kasal <kasal@ucw.cz>
8628 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8630 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Drop the
8631 initialization of `ac_cv_exeext', do not override it if it was
8632 already set, unless it was set to `no', for compatibility with
8633 Autoconf-2.13, and comment this.
8634 Do not export `ac_cv_exeext', Libtool hasn't needed this for years.
8635 (_AC_COMPILER_EXEEXT_DEFAULT): Likewise, do not export it.
8636 (_AC_COMPILER_EXEEXT_WORKS, _AC_COMPILER_EXEEXT_CROSS): Typos.
8637 * doc/autoconf.texi (Compilers and Preprocessors) <EXEEXT>:
8638 Document that this test may be overridden by setting
8641 2006-05-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8643 Revert these two patches:
8645 2006-04-06 Eric Blake <ebb9@byu.net>
8646 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_O): Inside cache
8647 check, s/ac_exeext/ac_cv_exeext/. Fixes regression introduced
8650 2006-04-01 Stepan Kasal <kasal@ucw.cz>
8651 Clean up _AC_COMPILER_EXEEXT* macros.
8652 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't try to
8653 detect exeext, it will be done by _AC_COMPILER_EXEEXT_O; just set
8654 ac_file to the name of the default output file and call
8655 _AC_COMPILER_EXEEXT_WORKS. Move the definition of ac_files and the
8656 initial `rm' of the candidate files...
8657 (_AC_COMPILER_EXEEXT): ... here and simplify them. Moreover, use
8658 the same list in subsequent `rm' calls, and for the temporary
8659 redefinition of ac_clean_files; call _AC_COMPILER_OBJEXT at the end,
8660 and don't call the other _AC_COMPILER_EXEEXT_* macros directly, use...
8661 (_AC_COMPILER_EXEEXT_TESTS): ... this new macro.
8662 (_AC_COMPILER_EXEEXT_O): Don't export ac_cv_exeext, it's not needed (or
8663 no longer needed) by libtool. Make it a cache check.
8664 (_AC_COMPILER_EXEEXT_CROSS): Remove the comment, it was obviously
8665 copied here by mistake.
8666 (AC_NO_EXECUTABLES): Redefine _AC_COMPILER_EXEEXT_TESTS, not
8667 _AC_COMPILER_EXEEXT.
8668 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX, AC_PROG_OBJC): Do not call
8669 _AC_COMPILER_OBJEXT directly.
8670 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
8672 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8674 * doc/autoconf.texi (Limitations of Usual Tools) < sed (`t')>:
8675 Fix description of how the buggy `sed' works.
8677 2006-05-25 Noah Misch <noah@cs.caltech.edu>
8681 * lib/Autom4te/XFile.pm (lock): Allow EOPNOTSUPP, besides
8682 ENOLCK. Only mention `make -j' when applicable. Only raise
8683 fatal errors when `make -j' is involved. Improve error message.
8685 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8687 * doc/autoconf.texi (Here-Documents): We now know more about
8688 the variable expansion in here documents bug.
8689 Thanks to Tim Rice and Stepan Kasal.
8691 * doc/autoconf.texi (Making testsuite Scripts): Add an example
8692 how to use TESTSUITEFLAGS. Suggested by Eric Blake.
8694 2006-05-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8696 * tests/autotest.at (Multiline command from M4 expansion):
8697 No failure to be expected if the shell quotes newlines in
8698 commands in the `set -x' output. Report by Tim Rice.
8701 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
8703 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Don't use shell
8704 expansion in the here-documents used by config.status, as that
8705 runs afoul of the Korn shell version M-12/28/93d bug described in
8706 the Autoconf manual, and this in turn causes a Coreutils 5.95 build to
8707 fail as described by Tim Rice and diagnosed by Ralf Wildenhues in
8708 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00082.html>.
8710 2006-05-23 Jim Meyering <jim@meyering.net>
8712 * lib/autoconf/functions.m4 (AC_FUNC_LSTAT_FOLLOWS_SLASHED_SYMLINK):
8713 Fix typo introduced with 2006-04-02 change. It reversed the sense
8716 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
8718 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Simplify ac_dA and
8719 ac_dB slightly, to save bytes in the script.
8720 Max out at 50 lines, rather than 96; this is more likely
8721 (though not guaranteed) to avoid obscure 'sed' failures.
8723 2006-05-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8725 * lib/autotest/general.m4 (AT_INIT): UnixWare `tr' may interpret
8726 `tr -d -' as bad option argument. Work around this by deleting
8727 an unrelated character.
8728 Report by Tim Rice <tim@multitalents.net>.
8730 2006-05-22 Paul Eggert <eggert@cs.ucla.edu>,
8731 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
8732 Stepan Kasal <kasal@ucw.cz>
8734 * doc/autoconf.texi (Particular Programs): Do not promise that
8735 we always prefer the GNU version of the program, and that we
8736 search according to PATH; both rules can have exceptions.
8737 Update description of AC_PROG_GREP, AC_PROG_EGREP, AC_PROG_FGREP,
8738 AC_PROG_SED. Move descriptions of limitations
8739 to the Limitations of Usual Tools section.
8740 (Limitations of Usual Tools) <sed>: Mention script length
8741 limitations with Solaris /usr/ucb/sed.
8742 <grep>: Fix wording for empty alternative. Mention that -c and
8743 -l should not be combined, and that -E and -F should not be
8746 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
8747 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8749 * lib/autoconf/programs.m4 (AC_PROG_SED): Catch script length
8750 limits in Solaris 8 /usr/ucb/sed by testing a long script.
8752 2006-05-22 Stepan Kasal <kasal@ucw.cz>
8754 * doc/autoconf.texi (Defining Symbols): Literal parameter of
8755 AC_DEFINE is now passed to m4_pattern_allow.
8756 * NEWS: Mention that; likewise for AC_SUBST.
8757 * lib/autoconf/general.m4 (AC_DEFINE_TRACE_LITERAL): Pass
8758 the parameter to m4_pattern_allow.
8759 * tests/tools.at: Add a check for that.
8761 2006-05-22 Stepan Kasal <kasal@ucw.cz>
8763 * lib/autoconf/status.m4: Fix typos.
8765 2006-05-21 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8767 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Remove
8768 only the files that this macro generates.
8770 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
8772 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: For
8773 the HP-UX sed limitation of 99 commands, labels do not count.
8774 * lib/autoconf/status.m4 (_AC_SED_CMD_LIMIT): Mention that
8776 (_AC_OUTPUT_HEADER): Revert the change from 2006-05-19.
8778 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
8780 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT):
8781 Import the following fix from coreutils:
8783 2006-01-13 Jim Meyering <jim@meyering.net>
8785 Invoke AC_CHECK_FUNCS(getmntent) unconditionally so that tests of
8786 $ac_cv_func_getmntent (e.g., in gl_LIST_MOUNTED_FILE_SYSTEMS) need
8787 not double-quote uses of that variable, to accommodate the rare
8788 case in which getmntent is available in none of the libraries
8789 checked. This happens at least on FreeBSD 5.0.
8791 2006-05-20 Paul Eggert <eggert@cs.ucla.edu>
8793 * lib/autoconf/general.m4 (AC_CONFIG_AUX_DIRS): Bring back
8794 ac_config_guess, ac_config_sub, and ac_configure, since evidently
8795 some other programs unwisely rely on these undocumented vars.
8796 But put in warning comments about them.
8797 Problem reported by Ralf Wildenhues in
8798 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00068.html>.
8799 * NEWS: Document that these variables are intended to go away.
8801 2006-05-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8803 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): Require AC_PROG_CXX,
8804 and set the language to C++ (analogous to the equivalent Fortran
8807 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): New macro.
8808 * doc/autoconf.texi (C++ Compiler): Document it.
8809 * lib/autoconf/fortran.m4 (_AC_PROG_FC_C_O): Adjust comment.
8812 2006-05-19 Paul Eggert <eggert@cs.ucla.edu>
8814 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Fix off-by-one bug
8815 that caused config.status to generate 100-command sed scripts; the
8816 portable limit is 99.
8818 2006-05-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8820 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Name temporary
8821 variable `ac_d' instead of `d' to avoid infringing namespace.
8822 Report by Ralf Menzel.
8824 2006-05-18 Paul Eggert <eggert@cs.ucla.edu>
8826 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Don't prepend
8827 $ac_top_build_prefix to $MKDIR_P if it's just 'mkdir -p'.
8828 * tests/tools.at (autoconf: subdirectories): New test, taken from
8829 the corresponding problem report by Ralf Wildenhues in:
8830 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00053.html
8832 * lib/autoconf/functions.m4 (AC_REPLACE_FNMATCH, AC_FUNC_FNMATCH_GNU):
8833 Quote some uses of shell variables if they might suffer unexpected
8834 globbing. This doesn't fix all instances of quoting problems that
8835 I found, just the easy ones that look safe.
8836 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR, _AC_INIT_HELP):
8837 (AC_CONFIG_AUX_DIR, AC_CONFIG_AUX_DIR_DEFAULT, AC_CONFIG_AUX_DIRS):
8838 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST, AC_CANONICAL_TARGET):
8839 (AC_CACHE_LOAD, AC_CACHE_SAVE): Likewise.
8840 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF, _AC_PATH_X_DIRECT): Likewise.

8847 2006-05-18 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8849 * bin/autoreconf.in ($help): Reword according to the manual.
8850 Suggested by Olly Betts.
8852 2006-05-17 Olly Betts <olly@survex.com> (tiny change)
8853 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8855 * bin/autoreconf.in: Pass the directory argument to
8856 `require_configure_ac'. Fix comment.
8857 * tests/torture.at (Configuring subdirectories): Expose this.
8858 Reported by Olly Betts.
8860 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8862 * lib/Automake/Configure_ac.pm, lib/Automake/Channels.pm,
8863 lib/Automake/FileUtils.pm, lib/Automake/Struct.pm: Sync from
8864 Automake as follows:
8866 * lib/Autom4te/Configure_ac.pm (find_configure_ac): Use
8867 `$configure_in' instead of `configure.in', to preserve
8868 directory component.
8870 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8872 * config/config.guess, config/config.sub, config/texinfo.tex,
8873 doc/make-stds.texi, doc/standards.texi: Sync from upstream.
8875 2006-05-14 Paul Eggert <eggert@cs.ucla.edu>
8877 * lib/autoconf/headers.m4 (AC_HEADER_STDBOOL): Fix overly-picky
8878 test for C99 conformance; (bool) 0.5 is an integer constant
8879 expression, but (bool) -0.5 is not. Problem reported by Fedor
8880 Sergeev in <http://forum.sun.com/jive/thread.jspa?threadID=96202>.
8882 2006-05-13 Paul Eggert <eggert@cs.ucla.edu>
8884 * doc/autoconf.texi (Particular Programs): AC_PROG_MKDIR_P now
8885 sets MKDIR_P, not mkdir_p, to avoid collisions with Automake.
8886 Warn about obsolete install-sh files. Remove stray sentence
8887 fragment and fix cross reference.
8888 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Don't insist on
8889 install -d; this undoes the 2006-05-10 change.
8890 (MKDIR_P): Mark with AN_MAKEVAR.
8891 (AC_PROG_MKDIR_P): Fall back on $ac_install_sh, not $INSTALL, so
8892 that we don't require $INSTALL to be thread-safe. Move comments
8893 out of generated code. Require AC_CONFIG_AUX_DIR_DEFAULT instead
8894 of AC_PROG_INSTALL. Output a message saying that we're checking
8895 mkdir -p. Set MKDIR_P rather than mkdir_p. Do special magic for
8896 MKDIR_P instead of AC_SUBST.
8897 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE, _AC_OUTPUT_CONFIG_STATUS):
8898 Special magic for MKDIR_P, too.
8899 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Remove comment that defeated
8901 * tests/local.at (AT_CHECK_ENV): mkdir_p -> MKDIR_P.
8903 2006-05-11 Paul Eggert <eggert@cs.ucla.edu>
8905 Sync from Automake, as follows:
8907 2006-05-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8908 * config/install-sh: Initialize IFS, so field splitting isn't
8910 * config/mkinstalldirs: Likewise.
8911 * config/missing: Remove superfluous quotes. Replace all uses of
8912 `[' by `test', for consistency, and for..
8913 * config/missing (sed_minuso, sed_output): New variables.
8914 (autom4te, help2man, makeinfo): Use them. Unifies detection of
8915 `-o FILE', `--output FILE', `--output=FILE', stricter regex.
8916 Fixes `missing' to detect `--output' for help2man. Fixes
8917 PR automake/483. Report by Dennis J. Linse.
8918 (autom4te): Document in `missing --help'.
8920 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
8922 * NEWS: New macro AC_PROG_MKDIR_P. AS_MKDIR_P is now more robust.
8923 * config/install-sh: Don't use 'path' to talk about file names,
8924 as per GNU coding standards. Close a race condition reported by Ralf
8925 Wildenhues and Stepan Kasal. There is still a race condition
8926 on hosts that predate Posix 1003.1-1992, but we can't help this.
8927 Don't mishandle weird characters like space on pre-Posix hosts.
8928 Invoke mkdir at most once per dir arg on pre-Posix hosts.
8929 * doc/autoconf.texi (Programming in M4sh): Cross-reference to
8930 AC_PROG_MKDIR_P from AS_MKDIR_P.
8931 (Limitations of Usual Tools): Cross-reference to AC_PROG_MKDIR_P
8932 from mkdir. Mention that Autoconf 2.60 install-sh is safe but
8933 earlier editions are not (including Automake 1.8.3).
8934 Do not suggest mkinstalldirs for thread-safety.
8935 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Insist on an 'install'
8936 that understands -d, so that AC_PROG_MKDIR_P can fall back on $INSTALL.
8937 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Make it more robust in the
8938 presence of special characters and race conditions.
8939 * tests/local.at (AT_CHECK_ENV): Add mkdir_p to the list of variables
8940 in Autoconf's name space.
8942 2006-05-10 Bruno Haible <bruno@clisp.org>
8943 and Paul Eggert <eggert@cs.ucla.edu>
8945 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): New macro, taken
8946 from Automake with minor changes.
8947 * doc/autoconf.texi (Particular Programs): Document AC_PROG_MKDIR_P.
8949 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
8951 * config/install-sh: Update to Automake CVS version, as follows:
8952 2006-04-25 Stepan Kasal <kasal@ucw.cz>
8953 * lib/install-sh: Simplify the expr implementation of dirname.
8954 2006-04-24 Paul Eggert <eggert@cs.ucla.edu>
8955 * lib/install-sh: Handle --, and diagnose unknown options.
8957 2006-05-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8959 * tests/Makefile.am (AUTOTEST): Use `$(MY_AUTOM4TE)' instead of
8960 `./autom4te' to create `./testsuite', since the `all' target
8961 will ensure its presence, but `installcheck' should not create
8962 the uninstalled wrappers.
8964 * tests/torture.at (Unusual Automake input files): Skip if we
8965 detect automake < 1.8.
8967 2006-05-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8969 * lib/autoconf/c.m4 (AC_PROG_CC_STDC): If ac_cv_prog_cc_stdc
8970 is set to `no', then that overrides and sets ac_cv_prog_cc_c89
8971 and ac_cv_prog_cc_c99 to `no', for backward compatibility.
8974 2006-05-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8976 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Take care not to
8977 munge (multiple) white space and other oddities.
8978 * tests/torture.at (AT_CHECK_AC_ARG_VAR): Make sure to M4-escape
8979 single quotes in variable assignment.
8980 (AC_ARG_VAR, configure invocation): Adjust tests to expose this
8981 and similar failures by adding multiple spaces, tabs, and other
8983 Report and different test suggested by Francesco Romani
8984 <fromani@gmail.com> and Andrew Church <achurch@achurch.org>.
8986 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): When we escape
8987 single quotes, we only need to search for single quotes; this
8988 both simplifies the search pattern, and makes us less
8989 susceptible to `echo' variations for arguments not containing
8991 (_AC_ARG_VAR_VALIDATE): Likewise.
8993 2006-05-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8995 * doc/autoconf.texi (Special Shell Variables) <IFS>: Document
8996 `$*' and IFS concatenation issue with traditional shells and
8997 bash-2.04. Report by Seanster@Seanster.com.
8999 2006-05-03 Bruno Haible <bruno@clisp.org>
9001 * doc/autoconf.texi (Limitations of Usual Tools): Identify more
9002 precisely which Mac OS X versions have the od problem.
9004 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
9006 * doc/autoconf.texi: Use @option systematically.
9008 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
9009 and Bruno Haible <bruno@clisp.org>
9011 * doc/autoconf.texi (Limitations of Usual Tools): Add a paragraph
9013 (Integer Overflow): Mention the special case of integer division
9016 2006-05-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9018 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Cater for
9019 traditional shells like the Solaris one that do not use the
9020 first IFS character for assembling `$*'.
9021 Prompted by a related report from autoconf_bug@nro.ca.
9023 2006-05-01 Paul Eggert <eggert@cs.ucla.edu>
9024 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9026 * doc/autoconf.texi (Limitations of Builtins, Limitations of Make):
9027 Mention more problems with the -e option.
9029 2006-04-30 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9032 * doc/autoconf.texi (Systemology): Mention the Heirloom Project.
9034 * doc/autoconf.texi (Introduction, Pointers): Use `@/' liberally
9035 in URLs to improve DVI formatted output (requires texinfo 4.6).
9036 (System Services, Systemology, Shellology): Likewise.
9037 (Limitations of Usual Tools): Rewrite Mac OS X example for nicer
9040 * doc/autoconf.texi (Fortran Compiler): Do not use `@ovar' in
9042 (Runtime): Fix macro argument names to match description:
9043 `action-if-found' -> `action-if-true' and similarly.
9044 (Obsolete Macros): Likewise.
9045 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE): Likewise.
9046 (AC_COMPILE_IFELSE, AC_TRY_COMPILE, _AC_LINK_IFELSE)
9047 (AC_LINK_IFELSE, AC_TRY_LINK, AC_COMPILE_CHECK): Likewise.
9049 2006-04-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9051 * doc/autoconf.texi (Limitations of Make): Clean up markup.
9054 * doc/autoconf.texi (Portable Shell): Allow wrapped URLs, for

9059 * doc/autoconf.texi (Limitations of Builtins): Document FreeBSD
9060 /bin/sh set unsorted output.

9079 2006-04-25 Paul Eggert <eggert@cs.ucla.edu>
9081 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Don't use AS_ERROR,
9082 since as_me isn't set yet.
9084 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
9086 Prepare for deprecation of AS_BASENAME and AS_DIRNAME, and fix
9087 a few minor bugs in this area.
9089 * doc/autoconf.texi (Programming in M4sh): Comment out the
9090 documentation of AS_BASENAME, for now.
9091 (Shell Substitutions): Do not use AS_DIRNAME in an example.
9092 (Limitations of Builtins) <basename>: Do not refer to
9094 * bin/autoconf.as (me): Don't use AS_BASENAME.
9095 (dir): Remove the unused variable.
9096 * lib/m4sugar/m4sh.m4 (_AS_DETECT_REQUIRED): Renamed from
9097 AS_DETECT_REQUIRED. All uses changed.

9107 (_AS_DIRNAME_SED): Renamed from AS_DIRNAME_SED. All uses changed.
9108 (AS_DIRNAME): Use "dirname --".
9110 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
9112 * doc/autoconf.texi (Runtime): Renamed from "Run Time". All uses
9113 of "run time" and "run-time" changed to "runtime", for consistency.

9116 * lib/autoconf/general.m4: Likewise.
9117 * lib/autoconf/headers.m4: Likewise.
9119 * doc/autoconf.texi (Run Time): Document the exit status situation
9120 with more accuracy and detail.
9122 2006-04-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9124 * doc/autoconf.texi (Introduction): The GNU Autoconf Macro
9125 Archive is not officially `GNU' any more. Update URL.
9126 (Defining Directories): Likewise
9127 * lib/autoconf/c.m4 (AC_C_RESTRICT): Update URL.
9129 2006-04-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9131 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Remove the leading
9132 newline from the `trap' code to finish `config.log'; the NetBSD
9133 /bin/sh resets the exit status after an empty command, as
9134 documented in doc/autoconf.texi.
9135 Reported by Dalibor Topic <robilad@kaffe.org>.
9137 2006-04-19 Paul Eggert <eggert@cs.ucla.edu>
9139 * doc/autoconf.texi (C Compiler): Clarify AC_C_TYPEOF.
9140 Suggested by Bruno Haible.
9142 2006-04-18 Paul Eggert <eggert@cs.ucla.edu>
9144 * configure.ac (ac_cv_sh_n_works): Don't try to test for it, since
9145 some shells (e.g., Solaris 8 /bin/sh) implement it verrrry slowly.
9146 Instead, just list the shells that we know work.
9147 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Remove 2nd arg. All uses
9148 changed. Be more cautious about the _cv_ variable.
9149 * tests/tools.at (Syntax of the shell scripts): Check the
9150 _cv_ variable once, at first, to avoid an internal autoconf error
9151 when sh -n does not work.
9153 2006-04-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9155 * lib/Autom4te/FileUtils.pm: Sync from Automake.
9157 2006-04-16 Paul Eggert <eggert@cs.ucla.edu>
9159 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Don't
9160 use ">&-" since we're only 99.999% sure that this is portable,
9161 and since the MinGW bug is fixed in a different way.
9162 * lib/autotest/general.m4 (AT_INIT): Likewise.
9164 2006-04-16 Stepan Kasal <kasal@ucw.cz>
9166 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Handle --recheck
9167 before opening config.log, to avoid hitting a bug on MinGW.
9169 2006-04-14 Paul Eggert <eggert@cs.ucla.edu>
9171 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Close
9172 AS_MESSAGE_LOG_FD before reopening it onto the log file.
9173 This works around a MinGW bug reported by Eric Paire.
9174 Make sure that all writes to the log file append to it,
9175 rather than possibly losing data.
9176 * lib/autotest/general.m4 (AT_INIT): Likewise.
9178 2006-04-14 Stepan Kasal <kasal@ucw.cz>
9180 * lib/Autom4te/FileUtils.pm (find_file): Fix a typo in the
9183 2006-04-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9187 * configure.ac (AC_INIT): Bump to 2.59d.
9189 2006-04-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9193 * Makefile.maint (news-date-check): Do not require a leading `*'
9194 before the release date in NEWS.
9196 2006-04-12 Stepan Kasal <kasal@ucw.cz>
9197 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9199 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If the templates for
9200 the instantiated file do not contain the string 'datarootdir'
9201 but contain @datadir@, @docdir@, @infodir@, @localedir@, or
9202 @mandir@, replace the reference '${datarootdir}' by the value.
9203 * tests/torture.at (datarootdir workaround): New test.
9204 * NEWS: Advertise this temporary fixup.
9205 Based on a patch by Bruno Haible, reported and analyzed by
9206 Paul Eggert and Noah Misch.
9208 2006-04-12 Eric Blake <ebb9@byu.net>
9210 * tests/autotest.at (Debugging a failed test): Fix comment.
9212 2006-04-12 Stepan Kasal <kasal@ucw.cz>
9214 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): Simplify the summary of
9215 all the changes since 2006-04-07.
9217 2006-04-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9219 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): If `ln -s file1 file2'
9220 succeeded, but `ln -s file dir' failed, take care to remove the
9221 leftover target before the next test, to prevent its spurious
9222 failure; also make sure `ln file dir' works before selecting it.
9223 Thanks to Keith Marshall for pointing this out.
9226 * lib/autotest/general.m4 (AT_INIT): Store quoted variable
9227 assignments in `at_debug_args', so that we put them correctly
9228 in the `run' script.
9229 * tests/autotest.at (Debugging a failed test): Unmark XFAIL.
9230 Reported by Eric Blake.
9232 2006-04-11 Eric Blake <ebb9@byu.net>
9234 * tests/autotest.at (AT_CHECK_AT): Add new argument, to allow
9235 top-level tests after micro-suite has been run. Used in...
9236 (Debugging a successful test, Debugging script and environment),
9237 (Debugging a failed test): ...these new tests. The first of these
9239 * lib/autotest/general.m4 (_AT_CREATE_DEBUGGING_SCRIPT): New
9240 macro, split out from...
9241 (AT_INIT): ...here, so that using -d also generates a run script.
9242 Document that -d inhibits top-level logging.
9243 * doc/autoconf.texi (testsuite Invocation): Document that -d only
9244 inhibits top-level logging; debug scripts are created.
9246 * lib/autotest/general.m4 (_AT_CHECK): Avoid syntax error on empty
9248 * tests/autotest.at (Empty test, Empty check): New test to check it.
9250 * lib/autoconf/c.m4 (AC_C_CONST, AC_C_VOLATILE): Avoid warnings
9253 2006-04-10 Stepan Kasal <kasal@ucw.cz>
9255 * tests/mktests.sh: Use "trap '' 0", not "trap 0". Do not touch
9256 the files if a problem appears. Make the empty *.at files
9257 read-only, too. Proposed by Ralf Wildenhues.
9259 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9261 * config/Makefile.am: Add comment to force updated Makefile.in.
9263 * lib/freeze.mk: Fix typo in comment. Unlike the last, white
9264 space only patch to this file, this patch causes the Makefile.in
9265 files that include freeze.mk to be updated, and thus have a
9266 newer time stamp again, which in turn makes a pristine CVS
9267 checkout have correct time stamps.
9269 * Makefile.maint (cvs-sv): New macro, to be used..
9270 (config.guess-url_prefix, config.sub-url_prefix)
9271 (texinfo.tex-url_prefix, standards.texi-url_prefix): ..here;
9272 point to CVS text checkout of Gnulib files.
9273 (copyright-check): Bump current year.
9274 (announcement): Do not hard-wire `./announce-gen'.
9275 (cvs-update): Propagate failures of `cvs' and `move-if-change'
9277 * Makefile.cfg (executable-update): Use `chmod a+x' instead of
9279 (wget_files): Update config.guess, config.sub, texinfo.tex by
9280 `wget-update', now that their URLs work again.
9282 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
9284 * doc/autoconf.texi (Particular Types): Don't use AC_CHECK_TYPE.
9285 Problem noted by Paul D. Smith.
9287 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9289 * doc/autoconf.texi: Remove unused words from word list.
9290 * .x-sc_prohibit_atoi_atof, .x-sc_space_tab, .x-sc_sun_os_names,
9291 .x-sc_trailing_space: New files.
9293 * doc/standards.texi: Sync from gnulib.
9295 * NEWS, doc/autoconf.texi (AC_LIBOBJ vs LIBOBJS): Mark
9296 `LIBOBJDIR' as experimental.
9298 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): MSYS `ln -s' fails
9299 with a target directory; it's internally implemented as `cp'
9300 anyway, but since Autoconf advertises the possibility to use
9301 a target directory when LN_S is `ln -s', we need to find out.
9302 Reported by Rolf Ebert <rolf.ebert.gcc@gmx.de> against MSYS,
9303 analyzed by Keith Marshall <keith.marshall@total.com>.
9307 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
9309 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Just output
9310 confdefs.h as-is. In general, if it has backslash-newline or the
9311 like, then it doesn't work either to sort or to remove empty
9314 2006-04-09 Stepan Kasal <kasal@ucw.cz>
9316 * tests/Makefile.am (AUTOCONF_FILES): Fix typo in the comment.
9318 2006-04-09 Alexandre Duret-Lutz <adl@gnu.org>
9320 * lib/autom4te.in (Automake-preselections): Preselect
9323 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>
9325 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Use '\'' for an
9326 apostrophe within a single-quoted string, as this is the usual
9327 tradition and is easier to read than '"'"'. Don't rely on the
9328 shell treating "$/" like '$/'. Use a more-consistent indenting
9331 2006-04-09 Eric Blake <ebb9@byu.net>
9333 * tests/autotest.at (Backquote command substitution),
9334 (Multiline backquote command substitution): Remove mistaken
9335 AT_NO_CMDSUBST from the 2006-03-14 patch, which was meant to be
9337 (Parenthetical command substitution, Multiline parenthetical
9338 command substitution): here.
9340 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>

9415 2006-04-07 Stepan Kasal <kasal@ucw.cz>
9417 Revert the patch from 2006-04-01 and only improve
9418 _AS_DETECT_BETTER_SHELL:
9420 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Do not optimize; do not
9421 skip nonexistent directories.
9422 (_AS_DETECT_BETTER_SHELL): The optimization is moved here--try
9423 only shell candidates which exist.
9424 (AS_UNAME): No need to give three parameters to _AS_PATH_WALK.
9425 * lib/autotest/general.m4 (AT_INIT): No need to give three
9426 parameters to _AS_PATH_WALK.
9428 2006-04-07 Stepan Kasal <kasal@ucw.cz>,
9429 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9431 * bin/autoupdate.in (handle_autoconf_patches): Change the way we
9432 distinguish m4sugar macros.

9435 test case by Noah Misch <noah@cs.caltech.edu>.
9437 2006-04-07 Stepan Kasal <kasal@ucw.cz>

9442 (AS_SHELL_SANITIZE): Remove DUALCASE=1.
9443 * doc/autoconf.texi (Special Shell Variables) <BIN_SH>: Say that
9446 2006-04-07 Eric Blake <ebb9@byu.net>
9448 * doc/autoconf.texi (Programming in M4sh): Document that
9449 AS_MKDIR_P exits the script on failure.
9450 * lib/autotest/general.m4: Remove redundant AS_ERROR.
9452 2006-04-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9454 * config/elisp-comp, config/install-sh, config/mdate-sh,
9455 config/missing, config/mkinstalldirs: Sync from Automake.

9470 Paul Eggert <eggert@cs.ucla.edu>,
9471 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9473 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): Fix the detection of
9474 whether `set' quotes correctly: redirect stderr of the tested
9475 `set', and use a subshell, for Ultrix; use `sed' instead of
9476 `grep' for zsh `set' which may write binary output; match only
9477 at the beginning of a line, to avoid false positives.
9478 In order to avoid false positives by unrelated variables with
9479 multiline content, put the dump algorithm in a subshell and
9480 unset all variables containing newlines (except some which are
9481 special to the shell). Warn about cache variables that are
9484 2006-04-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9486 * config/config.guess, config/config.sub, config/texinfo.tex:
9489 * tests/mktests.sh: Reword comments.

9527 ac_config_<foo>s again, sometimes normalized, sometimes not.
9528 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_LINKS):
9529 (AC_CONFIG_COMMANDS): Do not do so here.
9530 (_AC_CONFIG_REGISTER_DEST): Double quote the tags in macros _AC_LIST_TAGS
9531 and_AC_LIST_TAG_COMMANDS; fixes another regression introduced by the
9532 2005-07-25 rewrite. Noticed by Noah Misch.
9534 * lib/autoconf/general.m4 (AC_PRESERVE_HELP_ORDER): Do not define
9535 _AC_PRESERVE_HELP_ORDER, ...
9536 (AC_ARG_ENABLE, AC_ARG_WITH): ... use AC_PROVIDE_IFELSE insetad.
9538 * lib/autoconf/general.m4 (AC_ARG_VAR): Do not use m4_divert_once
9539 inside m4_expand_once; it is redundant.
9541 * lib/autoconf/general.m4 (_AC_INIT_HELP): Remove the broken support
9542 for --help from Cygnus `configure.'
9544 2006-04-06 Paul Eggert <eggert@cs.ucla.edu>

9557 * lib/autoconf/general.m4 (AC_PRESERVE_HELP_ORDER): New macro.
9558 (AC_ARG_ENABLE, AC_ARG_WITH): Adjust.
9559 * doc/autoconf.texi (Help Formatting): New node.
9560 * NEWS: Announce AC_PRESERVE_HELP_ORDER.
9562 2006-04-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9564 * TODO, config/Makefile.am, lib/freeze.mk, lib/autoconf/c.m4,
9565 lib/autoconf/specific.m4, lib/autoconf/status.m4,
9566 lib/autoconf/types.m4, lib/autotest/general.m4,
9567 tests/mktests.sh, tests/torture.at: White space cleanup:
9568 remove some SPACE before TAB, or add quoting ('' or @&t@).
9570 * NEWS, TODO, bin/autoreconf.in: `filesystem' -> `file system'.
9572 * doc/autoconf.texi (Shell Substitutions): Document `^' vs. `|'.
9574 2006-04-05 Eric Blake <ebb9@byu.net>
9576 * lib/autotest/general.m4 (AT_INIT): Prep AT_*_all, so that an
9577 empty test suite works.

9586 normalizing it, consistent it with previous releases.
9587 * tests/torture.at (Macro calls in AC_CONFIG_COMMANDS tags): New test.
9589 2006-04-05 Paul Eggert <eggert@cs.ucla.edu>
9591 * lib/m4sugar/m4sh.m4 (AS_BASENAME_EXPR, AS_DIRNAME_EXPR):
9592 Use simplified args that Eric Blake originally suggested.
9594 2006-04-04 Paul Eggert <eggert@cs.ucla.edu>
9596 * tests/mktests.sh: Don't use 'cat'; just read the files directly.
9597 Prefer 'sort -u' to 'sort | uniq'. Filter data before sorting it.
9598 Use 'comm' rather than N instances of grep; this also fixes a bug
9599 whereby substrings were incorrectly matched, causing us to not
9600 generate tests for AC_F77_NAME_MANGLING and AC_FUNC_LSTAT.
9601 (exclude_list): Exclude empty macros.
9602 (ac_exclude_list): Exclude AC_INCLUDES_DEFAULT.
9604 Use awk rather than grep -E or egrep, to avoid
9605 portability problems with regular expressions containing newlines.

9614 a subdirectory subject to Cygnus `configure'.
9615 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Likewise.
9617 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): Omit the bug
9618 report request when we have no AC_PACKAGE_BUGREPORT.
9620 2006-04-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9624 * tests/mktests.sh: Update copyright year in the header of the
9627 * lib/autoconf/c.m4 (AC_C_INLINE): Do not skip cleanup code.
9628 (AC_C_RESTRICT): Likewise. Furthermore, add a function with a
9629 typedef'ed restricted pointer, to catch a compiler bug on
9630 HP-UX 11.x, and fix warnings so it passes with -Werror.
9631 (_AC_PROG_CC_C99): Likewise.
9632 Reported by Albert Chin <china@thewrittenword.com>.

9642 2006-04-03 Noah Misch <noah@cs.caltech.edu>
9644 * lib/autoconf/general.m4 (AC_CACHE_SAVE): Use AC_MSG_NOTICE.
9646 2006-04-03 Eric Blake <ebb9@byu.net>
9648 * THANKS: Add myself.
9650 2006-04-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9652 * lib/autotest/general.m4 (AT_INIT): Add `at_testdir' to pointer

10478 comparing its address. Intel's interprocedural optimization was

10528 suggested by Ben Elliston. Handle weird characters correctly.
10530 2005-09-06 Stepan Kasal <kasal@ucw.cz>
10532 * lib/autoconf/libs.m4 (AC_SEARCH_LIBS): Merge the two AC_LINK_IFELSE
10533 calls, so that the final expansion of this macro is shorter.
10534 Create the conftest.$ac_ext outside the `for' loop, to speed the run.
10535 Do not use `break' in the argument to AC_LINK_IFELSE, it would skip
10536 the cleanup there. Use AS_VAR_* macros, to be more general.
10537 * tests/semantics.at (AC_SEARCH_LIBS): Check for the cleanup.
10539 * lib/autoconf/general.m4: Use AS_IF where appropriate.

10566 * lib/autoconf/general.m4 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST,
10567 AC_CANONICAL_TARGET): Define by AC_DEFUN, no need to use AC_DEFUN_ONCE;

10579 some evil values and relying on the fact that $* concatenates the
10580 parameters by the first character from IFS.
10582 2005-08-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
10583 Stepan Kasal <kasal@ucw.cz>
10585 * lib/autoconf/status.m4 (_AC_CONFIG_REGISTER_DEST): When the
10586 first header appears, define AH_HEADER.
10587 * doc/autoconf.texi (Configuration Headers): Document AH_HEADER.
10588 Update limitations about when to call AC_CONFIG_HEADERS.
10589 (Configuration Commands): Document that AC_CONFIG_COMMANDS_PRE
10590 parameter can call AC_SUBST, AC_DEFINE, or AC_CONFIG_FOOS; explain
10591 that AC_CONFIG_COMMANDS_PRE and AC_CONFIG_COMMANDS_POST are not
10592 ``Configuration Actions''; fix their index entries.
10594 * lib/autotest/general.m4 (AT_INIT): Process multiple keywords
10595 options correctly. Process N-M as M-N if M is smaller than N.
10596 Process ranges correctly so that N-N will run only N.
10597 Sort and uniquify the tests that will be run. If there is more
10598 than one test, reinsert the banners for the tests.
10599 * tests/autotest.at (Keywords): Unmark XFAIL.
10601 2005-08-23 Stepan Kasal <kasal@ucw.cz>
10603 * lib/autoconf/general.m4 (_AC_DEFINE_Q): Strip the parameter list
10604 before passing the macro name to AH_TEMPLATE.
10606 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): config.status
10607 now opens log after option processing; in particular, --version
10608 and --help do not touch config.log.
10610 * Makefile.maint: Revert the change from 2005-08-12.
10612 2005-08-22 Stepan Kasal <kasal@ucw.cz>
10614 * lib/autoconf/general.m4 (AC_ARG_ENABLE, AC_ARG_WITH): Factor out

10624 * doc/autoconf.texi (Defining Symbols, Changed Results):
10625 Prepend to LIBS, not append, in examples.
10627 2005-08-16 Stepan Kasal <kasal@ucw.cz>
10629 When building in place, set srcdir="."; suggested by Tim Van Holder.
10631 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Do this; to recognize
10632 build in place, we need ac_pwd, and thus have to AC_REQUIRE ...
10633 (_AC_INIT_DIRCHECK): ... this macro and AC_DEFUN both of them.
10634 * lib/autoconf/status.m4 (_AC_SRCDIRS): Fix a comment: srcdir="."
10635 does not mean "no --srcdir option".
10637 2005-08-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10639 * tests/autoscan.at (autoscan): New file.
10640 * tests/suite.at: Use it.

10642 Reported against Libtool by Gideon Go <gideon.go@gmail.com>.
10644 * tests/autotest.at (Keywords): Test keywords combinations.
10646 2005-08-12 Stepan Kasal <kasal@ucw.cz>
10648 * Makefile.maint (GZIP_ENV): When checking the help text of gzip,
10649 add "2>&1"; gzip 1.2.4 prints help on stderr.
10651 2005-07-27 Stepan Kasal <kasal@ucw.cz>
10653 * lib/autotest/general.m4 (_AT_DECIDE_TRACEABLE): The symbol at_reason
10654 was pushdef'ed twice while popped only once. Push it only once.
10655 (_AT_CHECK): Cosmetic changes to the "case $at_status" command.
10657 2005-07-26 Stepan Kasal <kasal@ucw.cz>
10659 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): The message is now

10664 * Makefile.maint: Update from Bison.
10666 * lib/m4sugar/m4sugar.m4 (m4_strip): Comment fix---change tab to
10667 "<tab>" in comment, so that the point is understandable.
10669 2005-07-25 Stepan Kasal <kasal@ucw.cz>
10671 Rewrite substantial part of lib/autoconf/status.m4.
10672 The main change is that CONFIG_FILES, CONFIG_HEADERS, CONFIG_LINKS,
10673 and CONFIG_COMMANDS are not processed in four separate loops.
10674 Instead, there is one main loop. This alows that the common code
10675 is expanded only once, thus config.status (and configure) is smaller.
10677 The registration mechnism in AC_CONFIG_FILES and cousins also changed;
10678 the AC_LIST_FILES and cousins macros are no longer used.
10680 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES, _AC_OUTPUT_HEADERS,
10681 _AC_OUTPUT_LINKS, _AC_OUTPUT_COMMANDS): Renamed to ...
10682 (_AC_OUTPUT_FILE, _AC_OUTPUT_HEADER, _AC_OUTPUT_LINK,
10683 _AC_OUTPUT_COMMAND): ..., respectively. These macros no longer
10684 contain the initialization, nor the for loop, nor the associated
10685 commands; all these go to ...
10686 (_AC_OUTPUT_MAIN_LOOP): ... this new macro, called from
10687 _AC_OUTPUT_CONFIG_STATUS.
10688 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST, _AC_CONFIG_SPLIT_FILE_IN):
10689 Nuked; the code was merged into _AC_OUTPUT_MAIN_LOOP.
10690 (_AC_OUTPUT_FILE): The creation of the sed script ...
10691 (AC_OUTPUT): ... and the setup of ac_vpsub goes to ...
10692 (_AC_OUTPUT_FILES_PREPARE): ... a new macro, also called from
10693 _AC_OUTPUT_MAIN_LOOP.
10694 (_AC_CONFIG_FILES, _AC_CONFIG_HEADERS, _AC_CONFIG_LINKS,
10695 _AC_CONFIG_COMMANDS): Use ...
10696 (_AC_CONFIG_FOOS): ... this new macro, which uses these ...
10697 (_AC_CONFIG_REGISTER, _AC_CONFIG_REGISTER_DEST): ... new macros.
10698 (_AC_CONFIG_FILE, _AC_CONFIG_HEADER, _AC_CONFIG_LINK,
10699 _AC_CONFIG_COMMAND, _AC_CONFIG_DEPENDENCIES): No longer needed.
10700 (_AC_CONFIG_DEPENDENCY): Update, it uses these ...
10701 (_AC_CONFIG_DEPENDENCY_DEFAULT, _AC_FILE_DEPENDENCY_TRACE_COLON):
10703 (_AC_CONFIG_UNIQUE): Update.
10704 (AC_LIST_FILES, AC_LIST_HEADERS, AC_LIST_LINKS, AC_LIST_COMMANDS):
10705 Replaced by this ...
10706 (_AC_LIST_TAGS): ... new common macro.
10707 (AC_LIST_FILE_COMMANDS, AC_LIST_HEADER_COMMANDS, AC_LIST_LINK_COMMANDS,
10708 AC_LIST_COMMAND_COMMANDS): Replaced by this ...
10709 (_AC_LIST_TAG_COMMANDS): ... new common macro.
10710 (_AC_CONFIG_COMMANDS_INIT): Moved top to the `registration' section;
10711 this didn't belong to the `config commands' section.
10712 (_AC_OUTPUT_COMMANDS_INIT): Don't initialize, m4_ifdef is our friend.
10713 (AC_CONFIG_COMMANDS_PRE, AC_OUTPUT_COMMANDS_PRE,
10714 AC_CONFIG_COMMANDS_POST): Moved to a new section, these didn't belong
10715 to the `config commands' section either.
10716 (AC_CONFIG_SUBDIRS): Don't touch diversion DEFAULTS.
10717 (_AC_LIST_SUBDIRS): Don't initialize, m4_ifdef is our friend.
10719 ... and many changes to the comments nearby.
10721 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): At the end of the day,
10722 set ac_subdirs_all='_AC_LIST_SUBDIRS'.
10723 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
10724 AC_CONFIG_COMMANDS(command:input,...) is no longer allowed.
10725 (#define header templates): The comment at the top of the generated
10726 header now includes the name(s) of the source file(s).
10728 Several unrelated small changes:
10730 * lib/autoconf/general.m4 (AC_CACHE_VAL): Be didactic, quote the first
10731 parameter to AC_DIAGNOSE.
10732 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS): Likewise.
10733 (_AC_LINK_FILES_CNT): Don't AU_DEFUN this; it causes confusing messages
10734 with autoupdate; use m4_define_default inside AU_DEFUNed AC_LINK_FILES.
10735 (AC_OUTPUT): In the compatibility code, use m4_ifvaln, to be consistent
10736 with AU::AC_OUTPUT.
10737 (AU::AC_OUTPUT): Don't double-quote $2 and $3, the compatibility code
10738 in AC_OUTPUT doesn't double-quote it either.
10739 * tests/tools.at (autoupdate): AU::AC_OUTPUT no longer double-quotes the
10742 2005-07-10 Stepan Kasal <kasal@ucw.cz>
10744 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Document which
10745 versions of Portland Group compiler produce single- and double-quoted
10746 -cmdline argument. Reported by Steven G. Johnson <stevenj@fftw.org>
10747 and Ole Holm Nielsen <Ole.H.Nielsen@fysik.dtu.dk>.
10749 2005-07-07 Paul Eggert <eggert@cs.ucla.edu>
10751 * tests/local.at (AT_CONFIG_CMP): Ignore lines like "LIBS=''" too.
10752 This is a corrected version of yesterday's patch.
10754 2005-07-07 Stepan Kasal <kasal@ucw.cz>
10756 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Report the full
10757 path, too; insert a "===" to emphasize the line.
10759 * lib/autoconf/general.m4 (AC_CANONICAL_BUILD): Rename
10760 ac_cv_build_alias to ac_build_alias.
10761 (AC_CANONICAL_HOST, AC_CANONICAL_TARGET): Simplify.
10763 On 2005-02-24, an unintentional AC_SUBST([CC]) was introduced; this
10764 change eliminates it. Problem reported by Alexandre Duret-Lutz.
10765 * lib/autoconf/general.m4 (_AC_ARG_VAR_PRECIOUS): Move the AC_SUBST ...
10766 (AC_ARG_VAR): ... here.
10767 (_AC_INIT_PREPARE): Call AC_SUBST for build_alias, host_alias and
10770 Keep a list of all precious variables and process them with one simple
10771 for loop, instead of expanding all commands, or, OTOH, complicated
10772 processing of output of "set".
10773 * lib/autoconf/general.m4 (_AC_ARG_VAR_PRECIOUS): Acumulate the
10774 variable names in new macro...
10775 (_AC_PRECIOUS_VARS): ... which will be assigned to ac_precious_vars.
10776 (_AC_ARG_VAR_STORE): New macro which writes to diversion PARSE_ARGS
10777 a loop to assign all ac_env_* and ac_cv_env_* variables.
10778 (_AC_ARG_VAR_VALIDATE): Use shell variable ac_precious_vars, divert
10780 (_AC_INIT_DEFAULTS): At the end, if _AC_PRECIOUS_VARS is set, assign
10781 its value to shell variable ac_precious_vars and call
10782 _AC_ARG_VAR_STORE and _AC_ARG_VAR_VALIDATE.
10783 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Don't call
10784 _AC_ARG_VAR_VALIDATE.
10786 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Move AC_LANG_PUSH(C)

10805 They are generated by the Tru64 v5.1B shell.
10807 2005-07-05 Stepan Kasal <kasal@ucw.cz>
10809 Fix my changes from 2005-07-01; reported by Noah Misch.
10810 * lib/autoconf/status.m4 (_AC_CONFIG_DEPENDENCIES): Fix the
10811 description, the macro now accepts only a single tag.
10812 (_AC_CONFIG_UNIQUE): Likewise; s/AC_File/[$1]/
10814 Fix cases when the varsions of Autoconf and Autotest don't match.
10815 Reported by Noah Misch.
10816 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Set also
10817 at_top_builddir, for compatibility with older autotest.
10818 * lib/autotest/general.m4 (AT_INIT): If at_top_build_prefix
10819 is not set, use at_top_builddir, for compatibility with older
10820 versions of autoconf.

10824 * bin/autom4te.in ($m4): Catch usages like --nesting-limit=2048.
10825 Problem reported by Patrick Welche.
10827 2005-07-03 Paul Eggert <eggert@cs.ucla.edu>
10829 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Use &, not |, in
10830 sed substitution command, so that we allow | in program prefixes
10831 and program suffixes. (& is a problem anyway; we're not fixing
10833 * lib/autoconf/status.m4 (AC_CONFIG_FILES): Likewise, for
10834 configure_input, top_builddir, srcdir, etc.
10835 * lib/autotest/general.m4 (AT_INIT): Likewise, for
10836 PATH_SEPARATOR in AUTOTEST_PATH.

10840 * lib/autoconf/general.m4 (AC_SITE_LOAD): Rewrite the
10841 for loop over config.site files using `set', to allow
10842 directory names containing IFS characters.
10844 2005-07-01 Paul Eggert <eggert@cs.ucla.edu>
10846 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Remove the tests for
10847 directories with weird names. Apparently some people like living
10848 on the edge. However, improve the test that "pwd" actually does
10849 report a name for the working directory.
10850 * NEWS: Remove the claim that we test for funny chars in dir names.
10852 2005-07-01 Stepan Kasal <kasal@ucw.cz>

10866 (Limitations of Usual Tools) <sed>: Another minor rephrasing.
10868 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Use a here
10869 document to output the default config_* lists to config.status.
10870 Don't recognize option --file, if the functionality is not there.
10871 Likewise for --header; moreover, recognize --he and --h as shortcuts
10872 for --help in that case.
10874 * lib/autoconf/status.m4: Fix the order of the "sections", so that it
10875 matches the order of execution. No code changed.

10894 * lib/autoconf/general.m4 (AC_ARG_VAR): Move next to _AC_ARG_PRECIOUS.
10896 * lib/autoconf/general.m4 (AC_SUBST_TRACE): New macro, to be traced
10897 instead of AC_SUBST; proposed by Alexandre Duret-Lutz.
10898 (AC_SUBST): Call it.
10899 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Call AC_SUBST_TRACE for
10900 the directory specific variables; but don't call it for configure_input.
10902 2005-06-28 Derek Price <derek@ximbiot.com>
10904 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: Reword recent
10907 2005-06-23 Paul Eggert <eggert@cs.ucla.edu>
10909 * NEWS: Don't worry about spaces in bindir etc. Only srcdir and working
10910 directory have inherent problems with special characters like spaces,
10911 due to limitations in Make syntax. Problem reported by Alexandre
10913 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Implement the above.
10914 Also, fix Tru64 porting problem with shell patterns,

10926 from Justace Clutter.
10927 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Put name of invalid
10928 variable into diagnostic. Make the diagnostic an error, not a warning,
10929 because we really don't support spaces and suchlike in dir names.
10930 (_AC_INIT_SRCDIR): Allow special characters in $ac_unique_file.
10931 Don't worry about backslashes in srcdir; it can't happen now.
10932 (_AC_INIT_PARSE_ARGS): Allow weird characters in ac_optarg.
10933 Simplify ac_optarg handling.
10934 (_AC_ARG_VAR_VALIDATE): Remove unnecessary and inconsistent quotes.

10942 (AT_CONFIG_CMP): Use sed instead of grep plumbing.
10944 * doc/autoconf.texi (Limitations of Usual Tools) <grep>: Mention
10945 that '\|' is not allowed in BREs; recommend using newline separated
10946 list of patterns instead of multiple -e options.
10948 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Remove an old comment.
10950 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Use AC_SUBST/2.

10960 (Special Shell Variables): Fix sed code this in the example.
10961 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Likewise; and fix a typo.
10962 * lib/autotest/general.m4 (AT_ARG_OPTION): Fix typo in the description.
10964 * lib/m4sugar/m4sugar.m4 (m4_split): If the parameter is empty,
10965 expand to the empty list. Don't use two pairs of m4_changequote,
10966 it's not necessary.
10968 2005-06-20 Derek Price <derek@ximbiot.com>
10970 * lib/m4/programs.m4 (AC_PROG_YACC): Declare YACC & YFLAGS precious.
10972 2005-06-17 Paul Eggert <eggert@cs.ucla.edu>
10974 * lib/m4sugar/m4sh.m4 (as_awk_strverscmp): Port to Solaris /bin/awk.
10975 * doc/autoconf.texi:
10976 Don't mention Solaris versions so much, if a
10977 problem is common to all extant versions of Solaris. Say "SunOS
10978 4" instead of "SunOS" for SunOS 4.
10979 (awk): Mention more of the limitations of traditional Awk.
10980 (cat): Don't talk about cat -v.

10984 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE): New macro.
10985 (AS_VERSION_COMPARE): New macro. The API is taken from CVS,
10986 but the implementation is entirely different and is designed
10987 to be compatible with glibc strverscmp.
10988 * tests/m4sh.at (AS_VERSION_COMPARE): New test.
10990 * doc/autoconf.texi (Limitations of Usual Tools): Mention expr bug
10991 on Mac OS X 10.4 reported by Peter O'Gorman in:
10992 http://lists.gnu.org/archive/html/autoconf-patches/2005-06/msg00041.html
10993 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT):
10994 Use shell builtins rather than 'expr', to work around expr bug.
10996 2005-06-10 Paul Eggert <eggert@cs.ucla.edu>
10998 * doc/autoconf.texi: "filesystem" -> "file system".
10999 "behaviour" -> "behavior".
11000 Warn about \(...\)* in Solaris sed (written by Ralf Menzel).
11001 * lib/autoconf/general.m4: Omit blank after ":" sed command,
11003 * lib/m4sugar/m4sh.m4: Likewise.
11004 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Work around problem
11005 with Solaris sed. Fix by Ralf Menzel and Stepan Kasal.

11012 * lib/m4sugar/m4sh.m4 (AS_VAR_TEST_SET): Work even if $1 contains
11013 quotes and backslashes. Patch from Derek Price.
11015 2005-06-10 Derek Price <derek@ximbiot.com>
11017 * doc/autoconf.texi (Programming in M4sh): Document AS_TR_CPP &
11020 2005-06-08 Paul Eggert <eggert@cs.ucla.edu>
11022 * lib/autotest/general.m4 (AT_INIT): Don't accept Solaris 9's diff
11023 -u, since it outputs chatter if the input files are the same.
11024 Problem reported by Ralf Menzel.
11026 2005-06-08 Derek Price <derek@ximbiot.com>
11028 * lib/m4sugar/m4sugar.m4: Undefine include & sinclude rather than
11029 renaming them since they are about to be redefined anyhow.
11031 2005-06-08 Derek Price <derek@ximbiot.com>
11033 * doc/autoconf.texi (Redefined M4 Macros): Add index entries for most
11034 redefined M4 macros to this node. Document m4_include & m4_sinclude.
11035 Move m4_undefine to alphabetical order.
11037 2005-06-07 Paul Eggert <eggert@cs.ucla.edu>
11039 * README: Recommend GNU M4 1.4.3 or later.
11040 * doc/autoconf.texi (Introduction): Likewise.
11041 Reword to avoid some formatting glitches.
11042 Use "#!/bin/sh", not "#! /bin/sh"; the space isn't needed these days.
11043 Clarify explanation of HP compiler bug.
11044 Redo example output tp match current CVS snapshot.
11045 Use @example.org in email addresses when the examples
11046 might get inadvertently cut-and-pasted into user code.
11047 Remove example of autom4te usage that doesn't seem to work now.
11048 Use modern AC_INIT (except when the example is meant to be
11049 shown with Autoconf 2.13).
11050 Update ksh info for Solaris 9 and later.
11052 Modernize description of Automake versions a bit.
11053 Don't claim a future version of Autoconf is near.
11054 * doc/install.texi: Reword to avoid some formatting glitches.
11056 2005-06-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11058 * doc/autoconf.texi: Add [] to examples, so that the manual
11059 follows its own advice about quoting better.
11060 Reword to avoid some formatting glitches.
11061 * doc/installt.exi: Reword to avoid some formatting glitches.
11063 * doc/autoconf.texi (Limitations of Builtins) <case>: Mention
11064 Tru64 ksh pattern matching bug. Reported against Libtool by
11065 Albert Chin <libtool@mlists.thewrittenword.com> and
11066 Nicolas Joly <njoly@pasteur.fr>.
11068 2005-06-06 Stepan Kasal <kasal@ucw.cz>
11070 m4_cdr of one-member list was [[]] (one-member list containing an
11071 empty string) instead of [] (an empty list. Callers were skewed to
11072 match this misbehaviour. As a consequence of this:
11073 - m4_foreach([x], [], [foo]) expanded to `foo', while
11074 - the expansion of m4_foreach([x], [[]], [foo]) was empty.
11075 This bug has been fixed:
11077 * lib/m4sugar/m4sugar.m4 (m4_cdr): If only one argument is given,
11078 expand to an empty string; print error msg if called without
11080 (m4_foreach, m4_map, m4_map_sep): Don't expect the previous
11081 misbehaviour; handle [] and [[]] correctly.
11083 2005-06-06 Stepan Kasal <kasal@ucw.cz>
11085 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Nuke ac_max_here_lines.
11086 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Simplify the sed
11087 scripts created and the loop applying them, use _AC_SED_CMD_LIMIT.
11089 2005-06-06 Ralf Menzel <menzel@ls6.cs.uni-dortmund.de> (trivial change)
11091 * doc/autoconf.texi (Limitations of Usual Tools): Solaris' awk cannot
11092 swallow records with more than 99 fields.
11093 * lib/autotest/general.m4 (AT_INIT): Use the awk builtin `split' to
11094 parse the long line.
11096 2005-06-04 Stepan Kasal <kasal@ucw.cz>
11098 * doc/autoconf.texi (Limitations of Usual Tools): AIX awk cannot
11099 swallow literals longer than 399. Reported by Ralf Wildenhues.
11100 * lib/autotest/general.m4 (AT_INIT): Pass $at_groups though stdin,
11101 to workaround this limitation.
11103 2005-06-03 Steven G. Johnson <stevenj@alum.mit.edu>
11105 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Find g95 in addition
11106 to gfortran, and make these the first two compiler names
11107 checked (following the general autoconf preference for gcc).
11109 2005-06-03 Stepan Kasal <kasal@ucw.cz>
11111 * tests/Makefile.am (check_SCRIPTS): Set to $(wrappers).
11112 (DISTCLEANFILES): Remove $(check_SCRIPTS).
11113 (testsuite): Make sure autotest.m4f is up-to-date before using it.
11115 2005-06-02 Paul Eggert <eggert@cs.ucla.edu>
11117 * lib/autotest/general.m4 (AT_INIT): Don't create a regular
11118 expression of unbounded size when processing the --list
11119 option. This runs afoul of a limit of 399 bytes per regular
11120 expression on AIX. Problem reported by Ralf Wildenhues.
11122 2005-06-01 Paul Eggert <eggert@cs.ucla.edu>
11124 * NEWS: Note yesterday's changes to AC_SUBST and AC_SUBST_FILE.
11125 * doc/autoconf.texi (Particular Headers): Reword example
11126 for multiline stdbool replacement.
11127 (Setting Output Variables): Reword text a bit. Don't
11128 give all the details about |#_!!_#|.
11129 Reword description of line replacement.
11131 2005-05-31 Dan Manthey <dan_manthey@partech.com>
11133 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Output variables may
11134 now contain newlines, and substituted files must be referenced on
11135 a line alone; the sed scripts to substitute them are now very
11137 (_AC_SED_CMD_LIMIT): Added; single place to store limit on how many
11138 commands can be put in a sed script portably.
11139 * doc/autoconf.texi (Setting Output Variables): Document above
11140 changes. (Particular Header Checks) <AC_HEADER_STDBOOL>: Give exaple
11141 use of multiline substitution.
11142 * tests/torture.at: No longer expect substitution of newline to fail.
11144 2005-05-27 Paul Eggert <eggert@cs.ucla.edu>
11146 * lib/m4sugar/m4sh.m4 (_AS_SHELL_FN_WORK): Fix diagnostics.
11147 From Ralf Menzel (trivial change).
11149 2005-05-25 Paul Eggert <eggert@cs.ucla.edu>
11151 * tests/local.at: Don't attempt to check for negated character
11152 classes in shell scripts. The test was too brittle.
11154 2005-05-25 Stepan Kasal <kasal@ucw.cz>
11156 * bin/autoconf.as: Don't use "shift 2"; it's not portable enough.
11157 * doc/autoconf.texi (Limitations of Builtins): Document this
11160 2005-05-24 Stepan Kasal <kasal@ucw.cz>
11162 * lib/m4sugar/m4sh.m4 (_AS_ECHO_LOG): New macro to factor out
11163 common code; used in many places in the tree.
11164 (AS_ESCAPE): Make the pattern a bit simpler; use \& insetad of \1.
11165 (_AS_ECHO_UNQUOTED): Move the macro lower; no code change.
11167 * lib/m4sugar/m4sugar.m4 (m4_ifset): Use m4_ifval.
11169 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Merge the two error
11170 messages when ac_unique_file is not found.
11171 (AC_CONFIG_MACRO_DIR): Simplify the `if' at the end.
11172 (AC_MSG_CHECKING, AC_MSG_RESULT): Put braces around the two echo
11173 commands, for consistency with AC_MSG_ERROR and such.
11175 * bin/autoconf.as: Make more use of "shift 2" in option processing.
11177 * bin/Makefile.am: Merge the two rules for creating scripts.
11179 2005-05-23 Stepan Kasal <kasal@ucw.cz>
11181 * lib/autoconf/general.m4 (AC_MSG_RESULT_UNQUOTED): Make
11182 obsolete; it was never documented.
11183 (AC_CACHE_CHECK): Use AC_MSG_RESULT instead.
11185 2005-05-20 Stepan Kasal <kasal@ucw.cz>
11187 * NEWS: @top_builddir@ is now a dirname, ac_top_builddir will follow.
11188 * lib/autoconf/status.m4 (_AC_SRCDIRS): Rename ...
11189 (ac_top_builddir): ... this ...
11190 (ac_top_build_prefix): ... to this; the old name is also kept, for
11191 backward compatibility.
11192 (ac_top_builddir_sub): New variable, without the trailing slash,
11194 (_AC_OUTPUT_FILES): s/@top_builddir@/$ac_top_builddir_sub/
11195 * doc/autoconf.texi (Configuration Actions): Rename
11196 ac_top_builddir to ac_top_build_prefix.
11197 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Rename
11198 at_top_builddir to at_top_build_prefix.

11201 2005-05-20 Stepan Kasal <kasal@ucw.cz>
11203 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Simplify the init
11206 2005-05-17 Stepan Kasal <kasal@ucw.cz>
11208 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Don't m4_quote the second
11209 argument to m4_foreach. I guess it was necessary in the past,
11210 but I think it's a no-op now.
11212 2005-05-17 Stepan Kasal <kasal@ucw.cz>
11214 * lib/autoconf/general.m4 (_AC_INIT_HELP): Merge two consecutive
11215 ``cat <<_ACEOF'' commands to one.
11216 (_AC_CANONICAL_SPLIT): Use expr, not ``echo|sed.''
11217 * lib/autoconf/status.m4: On various places, use expr instead of
11219 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST):
11220 (_AC_CONFIG_SPLIT_FILE_IN): New macros, to factor out common code.
11221 * lib/autotest/general.m4 (AT_INIT): Use expr to get the numbers from
11223 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Use awk to search for
11224 the wrong patterns between ``case'' and ``esac.'' The previous
11225 code had false positives.
11227 2005-05-14 Alexandre Duret-Lutz <adl@gnu.org>
11229 * lib/autoconf/functions.m4 (_AC_LIBOBJ_ALLOCA): Prepend ${LIBOBJDIR},

11289 abbreviations of --version and --debug.
11291 2005-05-10 Paul Eggert <eggert@cs.ucla.edu>
11293 * doc/autoconf.texi (Autoconf Language): Be more precise about
11294 quoting rules. Problems noted by Stepan Kasal.
11295 Also, throughout this document, be more careful about white space.
11296 "blank", "white space", and "space" all have different meanings
11297 and we should be careful to say what we mean.
11299 2005-05-05 Paul Eggert <eggert@cs.ucla.edu>
11301 Fix C++ related problems reported by Werner Lemberg.
11302 * doc/autoconf.texi (C++ Compiler): Mention .cpp extension.

11318 set by latest automake.
11320 2005-05-01 Paul Eggert <eggert@cs.ucla.edu>
11322 * doc/autoconf.texi (Limitations of Usual Tools): "expr '' \| ''"
11323 outputs 0 on GNU/Linux these days.
11325 2005-04-29 Paul Eggert <eggert@cs.ucla.edu>
11327 * doc/autoconf.texi (Autoconf Language): Add more description
11328 about quoting heuristics.

11331 2005-04-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11333 * lib/autotest/general.m4 (AT_KEYWORDS): Separate by space,
11336 * doc/autoconf.texi (External Software): Replace AC_DEFINE_UNQUOTED
11337 by AC_DEFINE; it was a mistake.
11338 From bug reported against libtool by Dalibor Topic <robilad@kaffe.org>.
11340 2005-04-25 Stepan Kasal <kasal@ucw.cz>
11342 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): A tiny optimization.
11344 2005-04-22 Stepan Kasal <kasal@ucw.cz>
11346 * doc/autoconf.texi (External Software): Quadrigraphs are not
11347 processed correctly in AS_HELP_STRING; avoid this in the examples.
11348 * lib/m4sugar/m4sh.m4 (AS_HELP_STRING): Add a FIXME about quadrigraphs.
11349 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Likewise; and rephrase the
11350 comment and reduce m4_default([foo], []) to [foo].
11351 (m4_strip): Update the explanation.
11353 2005-04-19 Paul Eggert <eggert@cs.ucla.edu>
11355 * lib/autoconf/general.m4 (_AC_INIT_PREPARE, _AC_RUN_IFELSE):
11356 Remove core.conftest.* too; it's generated by Tru64 5.1.
11357 Problem reported by Jennis Pruett.
11358 * lib/autoconf/functions.m4
11359 (AC_FUNC_SETVBUF_REVERSED, AC_FUNC_UTIME_NULL):
11360 Don't bother to remove core files; AC_RUN_IFELSE should do that
11363 2005-04-19 Stepan Kasal <kasal@ucw.cz>
11365 * lib/m4sugar/m4sugar.m4 (m4_bpatsubsts): Add the b- to comment, too.

11380 examples showing how to implement --with-* and --enable-* options.
11382 2005-04-13 Paul Eggert <eggert@cs.ucla.edu>
11384 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Look for configure.ac

11403 fails if %s isn't supported. Problem reported by Ralf Wildenhues.
11405 2005-03-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11407 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS):
11408 Merge `-z option' as well for the benefit of Solaris link flags. Pass
11409 whole-archive (-zallextract, -zdefaultextract) options in the hope of
11410 unique libraries, for the Sun Fortran 95 8.0 compiler. Bug reported
11411 against Libtool by Yury Puhalsky <pooh@cryptopro.ru>.
11413 2005-03-22 Paul Eggert <eggert@cs.ucla.edu>
11415 * NEWS: The configure command now warns you if you attempt to use
11416 a directory whose name contains a special character like space,
11418 * doc/autoconf.texi (Installation Directory Variables): Allow
11419 "," in file names. Do not use \@; it's not a portable regexp.
11420 * bin/Makefile.am (edit): Likewise.
11421 * lib/Makefile.am (edit): Likewise.
11422 * tests/Makefile.am (edit): Likewise.

11431 (_AC_INIT_SRCDIR): Use ac_pwd rather than invoking pwd.
11432 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Propagate
11433 ac_pwd, and quote srcdir.
11434 * lib/autotest/general.m4 (AT_INIT): Quote file name args.
11436 * doc/autoconf.texi: Fix some systematic formatting problems.
11437 ".)" needs a following @: if not at the end of a sentence, and
11438 similarly for "!)". "etc." should be preceded by a comma.
11439 "n-th" -> "@var{n}th". pdksh is still buggy, so update its date.
11441 2005-03-22 Bruno Haible <bruno@clisp.org>
11443 * doc/autoconf.texi (Input): Mention that AC_CONFIG_AUX_DIR's
11444 argument is often called 'build-aux'.
11446 2005-03-07 Stepan Kasal <kasal@ucw.cz>
11448 * doc/autoconf.texi (Quotation Rule Of Thumb): Mention that the
11449 macro AC_TRY_LINK is obsolete.
11450 (Installation Directory Variables): Change `AC_OUTPUT_FILES' to
11453 2005-02-24 Stepan Kasal <kasal@ucw.cz>
11455 * lib/autoconf/c.m4 (AC_PROG_CC): Be more careful to skip
11456 `/usr/ucb/cc'; use `cl.exe' to distinguish the MS compiler
11457 from a Common Lisp's `cl'.
11458 (AC_PROG_CXX): Behave according to the documentation: don't
11459 search for $ac_tool_prefix$CCC and $CCC, just set CXX=$CCC;
11460 make the variable CCC precious; use `cl.exe', not `cl'.

11463 Alexandre Duret-Lutz <adl@gnu.org>
11465 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin from
11466 /dev/null, as "configure" shouldn't read stdin, and this insulates
11467 us from problems (e.g., when testing for "cl"). Also, do this
11468 redirection before invoking "hostname" or "uname", and keep the
11469 original input stream available via...
11470 (AS_ORIGINAL_STDIN_FD): ... this new macro.
11471 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't
11472 bother with "</dev/null" since it's now done at the top of

11481 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
11483 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N_PREPARE): Don't set ECHO_C to
11484 newline if neither \c nor -n work, as that would output two
11485 newlines. Prefer -n to \c. Reported by Stepan Kasal.
11487 2005-02-12 Stepan Kasal <kasal@ucw.cz>
11489 * lib/m4sugar/m4sh.m4 (AS_IF): Define by m4_defun, not m4_define.
11490 This causes that any required macros inside will get before the if.
11491 * doc/autoconf.texi (autom4te.cache): A typo.
11493 2005-02-12 Paul Eggert <eggert@cs.ucla.edu>
11495 Undo previous change, except keep the change to
11496 lib/autoconf/programs.m4 that replaced grep with shell
11497 pattern-matching. This is because net-snmp configure reads stdin.
11498 Reported by Noah Misch.

11502 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin
11503 from /dev/null, as "configure" shouldn't read stdin, and this
11504 insulates us from problems (e.g., when testing for "cl").
11505 Suggested by Alexandre Duret-Lutz. Also, do this redirection
11506 before invoking "hostname" or "uname".
11507 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
11508 _AC_LINK_IFELSE): Undo previous change, as it's no longer needed.
11509 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Don't bother with
11510 "</dev/null" since it's now done at the top of 'configure'.
11511 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
11512 * lib/autoconf/programs.m4 (_AC_PATH_PROG_FLAVOR_GNU): Likewise.
11513 Also, replace grep with shell pattern-matching, to save a process.

11517 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
11518 _AC_LINK_IFELSE): Redirect stdin to /dev/null, in an attempt to
11519 avoid thinking that Allegro Common Lisp's "cl" command is a C++
11522 2005-02-09 Paul Eggert <eggert@cs.ucla.edu>
11524 * doc/autoconf.texi (Limitations of Usual Tools): Document that
11525 grep -q isn't portable. Improve grep -s explanation.
11526 Problem reported by Dan Manthey.

11533 2005-02-07 Paul Eggert <eggert@cs.ucla.edu>
11535 * doc/autoconf.texi: Use @acronym for DJGPP.
11536 Fix some @code's that should have been @env's, and vice versa.
11537 Sort environment variable names.
11538 Mention that shells no longer inherit IFS.
11539 Don't recommend PATH_SEPARATOR=';' so strongly.
11540 Mention that $RANDOM might expand to the empty string.
11541 "symlink" and "soft link" -> "symbolic link".
11542 Improve mktemp description (reported by Bruno Haible).

11580 CPPFLAGS to `configure' instead of setting it in `configure'.
11582 * lib/m4sugar/m4sh.m4 (AS_UNAME): Try only /usr/bin/hostinfo, not
11583 any `hostinfo' in $PATH, since hostinfo.exe is a popular file name

11636 * doc/autoconf.texi (Special Shell Variables): Mention _,
11637 BIN_SH, DUALCASE. Say that variables other than "status" are safe
11638 if they contain a lower-case letter. The DUALCASE problem was
11639 reported by Ralf Wildenhues.

11649 Unicos 9 sed limitations.
11650 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Try cf77 before fort77

11681 Simplify the implementation of m4_require (a.k.a. AC_REQUIRE).
11682 Update the long comment explaining it.
11684 m4_require no longer writes an ``is required by'' line to the
11685 execution stack. It contains only one bit of non-redundant
11686 information: that the macro was required, not called. And even
11687 this bit is useless in most situations: have you ever met a macro
11688 which both calls and requires the same macro?
11690 * lib/m4sugar/m4sugar.m4 (_m4_defun_pro): Don't push a diversion...
11691 (_m4_defun_pro_outer): ... only via this macro, for the outermost

11694 (m4_expansion_stack_pop): Remove the misplaced comment.
11695 (m4_require): Don't put the ``is required by'' line to the
11696 execution stack; slightly improve the out-of-a-defun error message.
11697 (_m4_divert_grow): New macro, counter for the temporary diversions.
11698 (_m4_require_call): Use it.
11699 * tests/m4sugar.at (m4_require): Expect output without the
11700 ``is required by'' messages.
11702 2005-01-28 Paul Eggert <eggert@cs.ucla.edu>
11704 * doc/autoconf.texi (Limitations of Usual Tools): Recommend X

11731 2005-01-21 Paul Eggert <eggert@cs.ucla.edu>
11733 * doc/autoconf.texi (Limitations of Builtins): Clarify that

11736 2005-01-20 Paul Eggert <eggert@cs.ucla.edu>
11738 * doc/autoconf.texi (Shell Substitutions): Fix typo in case statement.
11739 Warn about newline stripping in `` and $(). Update Solaris
11741 (Limitations of Builtins): Use expr "X...", not expr "x...", as
11742 X insulates us from future changes to Posix.
11743 (Limitations of Usual Tools): For AS_DIRNAME, warn about newline
11746 2005-01-19 Stepan Kasal <kasal@ucw.cz>
11748 * doc/autoconf.texi (Defining Symbols): Delete the false comment that

11791 * lib/m4sugar/m4sugar.m4 (_m4_divert): A typo in description.
11792 (_m4_divert_n_stack): New macro; the expansion is
11793 <newline>m4_divert_stack, if m4_divert_stack is defined, and void
11795 (m4_divert, m4_divert_push, m4_divert_pop, m4_init): Use it.
11796 (m4_divert_push, m4_divert_pop, _m4_defun_epi): Don't expand the word
11797 stored in _m4_divert_diversion or _m4_divert_dump.
11798 (m4_divert_pop): When the parameter is given, compare the symbolic
11799 name with the last diversion pushed on the stack. Previously, the
11800 current diversion was compared with the numeric value of the
11801 diversion given as the parameter.
11802 (m4_require): If the macro hasn't been expanded yet, call ...
11803 (_m4_require_call): this new macro.

11836 * bin/autoreconf.in (autoreconf_current_directory): AM_INIT_AUTOMAKE
11837 signals that the package uses Automake; a `Makefile.am' is typical but
11838 not essential. Reported by Magnus Therning.
11839 * tests/torture.at (autoreconf.): New banner.
11840 (autoreconf and non-AC configure): Rename to `Non-Autoconf

11883 * lib/autotest/general.m4 (AT_LINE): Don't add srcdir here, to
11884 avoid cluttering displayed messages. Rather, prepend srcdir where
11885 AT_LINE is used for log files.

12338 2004-08-02 Alexandre Duret-Lutz <adl@gnu.org>
12340 * lib/autom4te.in (Automake-preselections): Preselect
12341 AC_CANONICAL_BUILD and AC_CANONICAL_TARGET. Automake 1.9.1 will
12344 2004-07-29 Paul Eggert <eggert@cs.ucla.edu>
12346 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): Set BIN_SH, for
12348 * doc/autoconf.texi (Shellology): Mention BIN_SH.
12349 Document problem with "`""`" in pdksh POSIX mode.
12351 2004-07-27 Paul Eggert <eggert@cs.ucla.edu>
12353 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): Use "set -o posix"
12354 with pdksh, too. Problem reported by Patrick Welche via
12356 * doc/autoconf.texi (Shellology): Note that set -o posix is
12357 useful for pkdsh, too.
12359 2004-06-24 Paul Eggert <eggert@cs.ucla.edu>
12361 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Require
12362 _AS_UNSET_PREPARE, so that we can use $as_unset directly.
12363 Don't fail if ENV or BASH_ENV is readonly.
12364 (AS_SHELL_SANITIZE): Don't fail if ENV, MAIL, MAILPATH, LC_ALL,
12365 etc. are read only. Problem reported by Ludovic Courtes.
12367 2004-06-23 Noah Misch <noah@cs.caltech.edu>
12369 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): If the shell is
12370 zsh, disable GLOB_SUBST to avoid backslash handling problems.
12373 2004-06-04 Paul Eggert <eggert@cs.ucla.edu>
12375 * doc/autoconf.texi (File System Conventions): Warn about
12376 names like "aux". Problem reported by Eric Blake.
12378 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY (C)): Use division
12379 by zero instead of array size, so that we can use any arithmetic
12380 constant expression (instead of requiring an integer constant
12381 expression). This allows us to test expressions like DBL_MAX <
12382 LDBL_MAX, which didn't conform to the C standard using the old
12384 (AC_C_LONG_DOUBLE): Put back in the tests for LDBL_MAX and LDBL_EPSILON,
12385 now that we can do floating-point tests at compile time.
12387 2004-06-02 Paul Eggert <eggert@cs.ucla.edu>
12389 * lib/autoconf/c.m4 (AC_C_LONG_DOUBLE): Don't check LDBL_MAX
12390 and LDBL_EPSILON, as the resulting expression isn't an
12391 integer constant expression and violates the C standard.
12392 Problem reported by Nelson H. F. Beebe. Also, check
12393 for "L" suffix, and check that long double doesn't have
12394 worse range or precision than double, that mixed-mode
12395 arithmetic doesn't generate a diagnostic, that double
12396 constants fit in long double.
12398 2004-06-03 Kevin Ryde <user42@zip.com.au>
12400 * doc/autoconf.texi (Function Portability): Add notes on free(NULL),
12401 malloc(0) and realloc(NULL,size).
12403 * doc/autoconf.texi (Shell Substitutions): Spelling error reported by
12406 2004-05-31 Paul Eggert <eggert@cs.ucla.edu>
12408 * lib/autoconf/headers.m4 (HAVE_STDBOOL_H): Detect _Bool bug
12409 in HP aC++/ANSI C B3910B A.05.55 [Dec 04 2003]. Problem reported
12412 2004-05-26 Paul Eggert <eggert@cs.ucla.edu>
12414 * doc/autoconf.texi (Limitations of Builtins): Mention that ! COMMAND
12415 can be rewritten using if-then-else. Suggested by Bruno Haible.
12417 2004-05-25 Paul Eggert <eggert@cs.ucla.edu>
12419 * doc/autoconf.texi (testsuite Scripts): Fix typo.
12420 Problem reported by Stepan Kasal.
12422 2004-05-24 Paul Eggert <eggert@cs.ucla.edu>
12424 * tests/Makefile.am (autoconfdir): Fix to match comment (trivial
12425 change). Patch reported by Ralf Wildenhues in
12426 <http://mail.gnu.org/archive/html/bug-autoconf/2004-05/msg00092.html>.
12428 * lib/autoconf/functions.m4 (AC_FUNC_MBRTOWC): Don't assume that a
12429 function F exists if the compiler and linker let you compile an
12430 expression like (F != 0). Recent versions of GCC optimize away
12431 the reference to F in that case, since every function address must
12432 be nonzero, so the link succeeds even if F does not exist.
12433 Problem reported by Manu in
12434 <http://mail.gnu.org/archive/html/bug-gnu-utils/2004-05/msg00060.html>.
12436 * doc/autoconf.texi (Systemology): Standardize on the spelling of
12437 "Unix". Many uses changed.
12438 (Limitations of Builtins): Explain better why the ! command isn't
12441 2004-05-22 Alexandre Duret-Lutz <adl@gnu.org>
12443 * lib/autom4te.in (Automake-preselections): Preselect

12448 * doc/autoconf.texi (Function Portability): Add strerror_r, cross
12449 referencing AC_FUNC_STRERROR_R.
12451 * doc/autoconf.texi (Particular Functions): In AC_FUNC_CLOSEDIR_VOID,
12452 note pessimistic assumption when cross compiling.
12454 2004-05-16 Paul Eggert <eggert@cs.ucla.edu>
12456 * doc/autoconf.texi (Limitations of Make): Note that BSD make
12457 (until 2004) invoked subcommands with sh -e, contra POSIX.
12458 Reported by Kevin Ryde.
12460 2004-05-10 Eric Sunshine <sunshine@sunshineco.com>
12462 * programs.m4 (_AC_PROG_GREP): Fixed bug where PATH argument handed to
12463 _AC_PATH_PROG_FEATURE_CHECK contained leading whitespace (i.e.
12464 " $PATH:/usr/xpg4/bin"). This resulted in bogus tests, such as
12465 `test -f " /usr/bin/grep"', which _always_ failed.
12466 (AC_PROG_SED): Ditto bogus PATH fix.
12467 * autoconf.texi (AC_PROG_GREP): Properly document that this macro
12468 requires that grep correctly supports _multiple_ `-e' options, rather
12469 than stating only that grep should accept `-e'.
12471 2004-05-03 Paul Eggert <eggert@cs.ucla.edu>
12473 Port to C99, which requires that 'exit' be declared.
12475 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Use AC_INCLUDES_DEFAULT
12476 to ensure that stdlib.h is included.
12477 * lib/autoconf/functions.m4 (_AC_LIBOBJ_ALLOCA, AC_FUNC_SETPGRP,
12478 AC_FUNC_STRTOD, AC_FUNC_SETVBUF_REVERSED, AC_FUNC_FORK, _AC_FUNC_FORK,
12479 _AC_FUNC_VFORK, AC_FUNC_WAIT3): Likewise.
12480 * lib/autoconf/specific.m4 (AC_SYS_RESTARTABLE_SYSCALLS): Likewise.
12481 * lib/autoconf/types.m4 (AC_TYPE_GETGROUPS): Likewise.
12482 * lib/autoconf/headers.m4 (AC_HEADER_STDC): Include <stdlib.h>
12483 when using 'exit' in a test; C99 requires that 'exit' be declared.
12485 2004-05-02 Paul Eggert <eggert@cs.ucla.edu>
12487 * doc/autoconf.texi (Particular Programs): AC_PROG_GREP
12488 now prefers 'grep' implementations that accept -e.
12489 (Limitations of Usual Tools): Describe problems of traditional
12490 egrep and fgrep with long input lines, and of traditional grep
12492 * lib/autoconf/programs.m4 (AC_PROG_GREP): Check for -e, too.
12493 (_AC_PROG_GREP): Assume 3rd arg is properly quoted for the shell.
12494 All callers changed. Append /usr/xpg4/bin to the PATH, for
12496 (_AC_FEATURE_CHECK_LENGTH): Discard stderr, so we don't bother
12497 the user with complaints about multiple -e options.
12498 * tests/local.at (AC_STATE_SAVE): Use $GREP, not grep.
12499 Define it with AC_PROG_GREP.
12500 * configure.ac (AC_PROG_GREP): Add.
12501 * lib/freeze.mk (GREP): New macro.
12503 2004-05-02 Eric Sunshine <sunshine@sunshineco.com>
12505 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Consult $SHELL as
12506 a possible candidate only after all others fail, rather than
12507 consulting it first. This improves backward compatibility by
12508 better reflecting the way shell selection occurred in previous
12509 versions of Autoconf, and should help to avoid triggering latent
12510 problems in other packages, such as the one in Automake where zsh
12511 is not handled robustly:
12512 http://mail.gnu.org/archive/html/automake/2004-04/msg00095.html
12513 Although it is not Autoconf's responsibility to work around
12514 problems in Automake, it nevertheless makes sense to avoid
12515 introducing unnecessary incompatibilites.
12517 2004-04-22 Albert Chin-A-Young <china@thewrittenword.com>,
12518 Gary V. Vaughan <gary@gnu.org>
12520 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Don't guess
12521 how deeply nested we are when a suitable tool is found, set the
12522 ac_path_TOOL_found flag.
12523 (_AC_PATH_PROG_FEATURE_CHECK): Encapsulate knowledge of how deeply
12524 nested we are in this macro. Break out of all 3 nested loops if
12525 ac_path_TOOL_found is set.
12527 2004-04-21 Gary V. Vaughan <gary@gnu.org>
12529 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Break out
12530 of the _AS_PATH_WALK loop too if GNU flavor is found.
12532 2004-04-21 Alexandre Duret-Lutz <adl@gnu.org>
12534 * doc/autoconf.texi (Limitations of Make): Update documentation
12535 for `$<'. New entry `Long lines', based on a report from Simon
12536 Josefsson. Augment the documentation for SHELL = @SHELL@ with a
12537 paragraph about DJGPP, based on a mail from Richard Dawe.
12539 2004-04-20 Paul Eggert <eggert@twinsun.com>
12541 * tests/c.at (C keywords): Don't assume that GCC supports
12542 "restrict" and "inline", as sufficiently-old GCC versions do not
12543 (also, GCC configured to be in pedantic C89 mode does not).
12544 Problem reported by Sumit Pandya in:
12545 http://mail.gnu.org/archive/html/autoconf/2004-04/msg00092.html
12547 * lib/autoconf/c.m4 (_AC_PROG_CC_G, _AC_PROG_CXX_G): Don't
12548 consider -g to work if it generates warnings when plain compiles
12549 don't. Problem reported by Braden McDaniel in:
12550 http://mail.gnu.org/archive/html/autoconf-patches/2003-07/msg00014.html
12552 * doc/autoconf.texi (Slashes): New section, to document a problem
12553 reported by Jim Meyering in:
12554 http://mail.gnu.org/archive/html/bug-coreutils/2004-02/msg00060.html
12556 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Remove potential
12557 linker output files before linking, to work around IRIX 6 linker bug.
12558 Problem reported by Rainer Orth in:

12561 2004-04-20 Gary V. Vaughan <gary@gnu.org>
12563 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Make the
12564 best tool so far counter rely on the tool path variable name to
12565 avoid checks for one tool being affected by the results of running
12566 the length check on a previous tool.
12568 * lib/autoconf/programs.m4 (_AC_PROG_GREP): Take an additional
12569 match expression argument, as different greps have different
12570 regular expression flavours.
12571 (AC_PROG_FGREP): Pass 'FGREP'. fgrep treats all match chars as
12573 (AC_PROG_EGREP): Pass 'EGREP$'.
12574 (AC_PROG_GREP): Pass 'GREP$'.
12576 2004-04-20 Albert Chin-A-Young <china@thewrittenword.com>
12578 * lib/autoconf/programs.m4 (AC_PROG_GREP): Cache variable
12579 is `ac_cv_path_GREP', not `oc_cv_path_GREP'.
12581 2004-03-29 Paul Eggert <eggert@twinsun.com>
12583 * doc/autoconf.texi (Particular Headers, Particular Types, Generic
12584 Types, Specific Compiler Characteristics, System Services,
12585 Obsolete Macros): Use 'long int', 'short int', 'unsigned int'
12586 etc. consistently instead of 'long', 'short', 'unsigned' etc.
12587 * lib/autoconf/c.m4 (AC_LANG_INT_SAVE(C), AC_C_BIGENDIAN): Likewise.

12601 * doc/autoconf.texi (Particular Structures): AC_STRUCT_TIMEZONE
12602 now defines HAVE_DECL_TZNAME if it is declared, when
12603 HAVE_STRUCT_TM_TM_ZONE is not defined.
12604 * lib/autoconf/types.m4 (AC_STRUCT_TIMEZONE): Implement this.
12605 Do not assume atoi. Rely on HAVE_DECL_TZNAME when testing

12612 thanks to Paul Eggert.
12614 2004-03-26 Steven G. Johnson <stevenj@alum.mit.edu>
12616 * lib/autoconf/fortran.m4 (_AC_PROG_FC): new name of Intel
12617 Fortran compiler is ifort, also added pghpf; thanks to Nelson

12706 AC_SUBST provides no portable way to escape literal newlines.
12708 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS): Ignore all
12709 flags of the form -lcrt*.o, not just -lcrt[01].o and -lcrtbegin.o.
12710 Darwin uses -lcrt2.o and there's little point to cataloging all
12711 the system variants. Partial fix reported by Andreas Waechter in:

12787 * lib/autoconf/general.m4 (_AC_INIT_COPYRIGHT): Add 1992 thorugh
12788 2003 (except 1997) to the list of copyright years. This undoes
12789 the 2003-05-22 change, which removed the older years from the list.
12790 * lib/autoconf/status.m4 (AC_OUTPUT): Update copyright date to 2004.

12795 * lib/autoconf/programs.m4 (AC_PROG_GREP): New macro to test for a
12796 grep or ggrep program in PATH that accepts as long lines as
12798 * lib/autoconf/programs.m4 (_AC_PROG_GREP): Factor out the core of
12800 (AC_PROG_EGREP, AC_PROG_FGREP): Use it to find best available
12801 egrep and fgrep respectively if $GREP -E/-F don't work.
12802 (_AC_PATH_PROG_FEATURE_CHECK): Factor out the common core of
12803 _AC_PROG_GREP, and AC_PROG_SED.
12804 (_AC_FEATURE_CHECK_LENGTH): New helper macro for finding the
12805 longest input length accepted by a command.
12806 (AC_PROG_SED): Use it.
12807 * doc/autoconf.texi (Particular Programs): Document the changes.
12810 2004-01-27 Paul Eggert <eggert@twinsun.com>
12812 * bin/autoconf.as ($version): Update copyright from 2003 to 2004.
12813 * bin/autoheader.in, bin/autom4te.in, bin/autoreconf.in,
12814 bin/autoscan.in, bin/autoupdate.in, bin/ifnames.in: Likewise.
12815 * lib/autoconf/general.m4 (_AC_INIT_COPYRIGHT): Likewise.
12817 * Makefile.in, aclocal.m4, configure, bin/Makefile.in,
12818 bin/autoconf.in, config/Makefile.in, config/config.guess,

12836 * doc/autoconf.texi (Default Includes): Include <stdint.h> even if
12837 HAVE_INTTYPES_H is defined. This is needed on Tru64 5.1b with
12838 Compac C V6.5-207 (dtk), which defines uintmax_t in <stdint.h> but
12839 not <inttypes.h>. Problem reported by Tim Mooney in
12840 <http://mail.gnu.org/archive/html/bug-coreutils/2004-01/msg00147.html>.
12841 * lib/autoconf/headers.m4 (_AC_INCLUDES_DEFAULT_REQUIREMENTS):
12844 * lib/autoconf/programs.m4 (AC_PROG_SED): Use diff, not sed;
12845 otherwise "make check" fails because it forbids cmp (I guess
12846 because cmp treats files as binary on DOS-like systems).
12848 * tests/mktests.sh: Update copyright date to 2004, since some tests
12849 have changed in 2004.
12851 2004-01-23 Gary V. Vaughan <gary@gnu.org>

12854 non-truncating sed or gsed program in PATH.
12855 * tests/acprograms.at: Add it.

12859 2004-01-15 Paul Eggert <eggert@twinsun.com>
12861 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Try -std, not -std1, since
12862 -std1 disables some useful extensions on Tru64. Problem reported
12863 by N. Lichtmaier in
12864 <http://mail.gnu.org/archive/html/autoconf/2004-01/msg00100.html>.
12866 2004-01-14 Paul Eggert <eggert@twinsun.com>
12868 * doc/autoconf.texi (Programming in M4sh): Document that
12869 AS_MKDIR_P succeeds if the destination is a symbolic link
12870 to an existing directory.
12871 (Limitations of Usual Tools): Note that mkdir -p might not
12872 succeed on symlinks to directories.
12874 2004-01-13 Paul Hilfinger <hilfinger@CS.Berkeley.EDU>
12876 * lib/autoconf/autoupdate.m4 (AU_DEFUN): Grammar fix in comment.
12877 * bin/autoheader.in: Grammar fix in message.
12878 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P):
12879 Test for dir before calling mkdir -p. (trivial changes)
12881 2004-01-13 Eric Blake <ebb9@byu.net>
12883 * doc/autoconf.texi (Obsolete Macros): In AC_TRY_COMPILE and
12884 AC_TRY_LINK, s/AC_LANG_SOURCE/AC_LANG_PROGRAM/. (trivial change)
12886 2004-01-10 Jim Meyering <jim@meyering.net>
12888 * doc/autoconf.texi (Running the Preprocessor): Correct grammar.
12890 2004-01-09 Paul Eggert <eggert@twinsun.com>
12892 * lib/autoconf/general.m4: Fix bug: AC_CHECK_SIZEOF evokes a warning
12893 with `autoconf -Wall,error'. Bug reported by Eric Blake in:
12894 http://mail.gnu.org/archive/html/autoconf-patches/2004-01/msg00000.html
12895 (_AC_COMPUTE_INT_COMPILE): Invoke _AC_COMPILE_IFELSE, not
12896 AC_COMPILE_IFELSE, since we now assume our caller invokes
12897 AC_LANG_COMPILER_REQUIRE, for symmetry with _AC_COMPUTE_INT_RUN.
12898 (_AC_COMPUTE_INT_RUN): Likewise, for _AC_RUN_IFELSE instead
12899 of AC_RUN_IFELSE; this avoids the warning mentioned above.
12900 (_AC_COMPUTE_INT): Invoke AC_LANG_COMPILER_REQUIRE.
12902 2004-01-07 Paul Eggert <eggert@twinsun.com>
12904 * lib/autoconf/general.m4 (_AC_LIBOBJS_NORMALIZE): Avoid \$ inside
12905 `"'...'"`, as it's confusing (and I suspect it may not work on
12906 some platforms). The code was incorrect anyway, as it assumed
12907 that \$ evaluated to itself in that context. Reported by
12908 Alexandre Duret-Lutz.
12910 2004-01-07 Alexandre Duret-Lutz <adl@gnu.org>
12912 * lib/autom4te.in (Automake-preselections): Preselect AC_LIBTOOL_TAGS
12913 and _LT_AC_TAGCONFIG.

12940 * lib/autoconf/general.m4 (AC_ARG_PROGRAM):
12941 Use "rm -f" to remove conftest.sed, not plain "rm".
12942 Bug reported by David Relson in
12943 <http://mail.gnu.org/archive/html/autoconf/2004-01/msg00011.html>.
12945 * Makefile.am (autom4te-update):
12946 Replace "rm -rf" and "rm -fr" with "rm -f -r", as POSIX requires.
12947 * Makefile.maint (my-distcheck, do-po-update): Likewise.

12962 * doc/autoconf.texi (Limitations of Usual Tools): Mention that cc
12963 -c -o might not work. From a suggestion by Kevin Ryde.
12964 (C Compiler, Generating Sources, Limitations
12965 of Usual Tools, Limitations of Make, Making testsuite Scripts):
12966 Don't put '-o' after non-options, as POSIX doesn't allow this.
12967 Mention that cc's name might be gcc or c89 or whatever.
12969 2004-01-04 Kevin Ryde <user42@zip.com.au>
12971 * doc/autoconf.texi: Add various further index entries.

12978 2003-12-27 Alexandre Duret-Lutz <adl@gnu.org>
12980 * doc/autoconf.texi (Limitations of Make) <Automatic rule rewriting>:
12981 Documents OSF1/Tru64 make behavior. Replace `VPATH = ../src' by
12982 `VPATH = ../pkg/src' in examples to make the OSF1/Tru64 make
12983 explanation clearer.
12985 2003-12-24 Andreas Schwab <schwab@suse.de>
12987 * doc/autoconf.texi (Default Includes): Fix misspelling of

12993 * configure: Regenerate.
12994 * tests/atlocal.in: Store the result here.

12997 of explicitly testing.
12998 (AT_CHECK_PERL_SYNTAX): Moved from tools.at.
12999 (AT_CHECK_AUTOCONF): Test for the configure script syntax.
13000 * tests/tools.at (Syntax of the shell scripts): Simplify

13075 the expanded body, consistently with other macros such as AC_USG.
13077 2003-11-17 Paul Eggert <eggert@twinsun.com>
13079 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Put at least 14 bytes
13080 into the initial confdefs.h, to work around a bug in NextStep 3.3
13081 patch 3 reported by Eric Sunshine.
13083 2003-11-15 Kevin Ryde <user42@zip.com.au>
13085 * doc/autoconf.texi (Using System Type): Revise, showing $host rather
13086 than $target since the latter is not usual, add guidelines on when to
13087 use or not use the system type.

13237 (Parentheses): New section.
13239 2003-10-15 Kevin Ryde <user42@zip.com.au>
13241 * doc/autoconf.texi (Function Portability): Add @prindex for exit.
13242 Add putenv and unsetenv. Add sysconf _SC_PAGE_SIZE.
13244 2003-10-13 Nathanael Nerode <neroden@gcc.gnu.org>
13246 * lib/autoconf/functions.m4 (AC_FUNC_FORK): Trivial fix for vfork
13249 2003-10-11 Steven G. Johnson <stevenj@alum.mit.edu>
13251 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Use the new official
13252 name for the GNU Fortran 95+ compiler, 'gfortran', not 'g95'.
13254 2003-10-10 Andreas Schwab <schwab@suse.de>
13256 * bin/autoheader.in: Avoid empty first line in --version and
13258 * bin/ifnames.in: Likewise.
13260 2003-10-09 Paul Eggert <eggert@twinsun.com>
13262 * lib/Autom4te/XFile.pm: Don't assume -j is solo.
13263 Issue a more-informative diagnostic.
13264 Problems reported by Eric Sunshine.
13266 2003-10-08 Steven G. Johnson <stevenj@alum.mit.edu>
13268 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Omit quoted
13269 -mGLOB_options_string stuff for Intel ifc, which can cause
13270 _AC_FC_LIBRARY_LDFLAGS to fail. Use (faster) case for
13271 pattern-matching instead of grep.
13273 2003-10-08 Steven G. Johnson <stevenj@alum.mit.edu>
13275 * doc/autoconf.texi: Document new FC Fortran macros.
13277 2003-10-08 Gary V. Vaughan <gary@gnu.org>
13279 * lib/autoconf/general.m4 (AC_CONFIG_MACRO_DIR): Stub out a macro
13280 that future autopoint/aclocal/automake/autoreconf will be able
13281 to trace to find where to install local m4 macros.
13282 * doc/autoconf.texi (Input): Document it.
13285 2003-10-06 Gary V. Vaughan <gary@gnu.org>
13287 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS): Add
13288 -lcrtbegin.o to list of ignored flags and fix underquoting of
13291 2003-10-04 Steven G. Johnson <stevenj@ab-initio.mit.edu>
13293 * lib/autoconf/fortran.m4 (_AC_PROG_FC_G): Use language-specific
13294 cache variable instead of $G77 to decide whether to include -O2,
13295 since $G77 is specific to Fortran 77.
13297 2003-10-03 Steven G. Johnson <stevenj@alum.mit.edu>
13299 * lib/autoconf/fortran.m4 (AC_FC_FREEFORM): Support Absoft "-f
13300 free" flag. Re-order flags tested into rough order of popularity.
13302 2003-10-03 Steven G. Johnson <stevenj@alum.mit.edu>
13304 * lib/autoconf/fortran.m4 (AC_PROG_FC): Reverse the order of the
13305 arguments so that it can be used with syntax identical to
13306 AC_PROG_F77, and so that we can more easily decide to
13307 remove/deprecate the DIALECT optional argument in the future if it
13308 proves troublesome.
13309 (AC_FC_FREEFORM): Exit 77 upon failure to fix test suite for
13310 non-freeform-supporting compilers. Document freeform flags.
13312 2003-10-03 Akim Demaille <akim@epita.fr>
13314 * configure.ac: Look for emacs, not macs.
13315 Reported by Eric Sunshine.
13317 2003-10-03 Akim Demaille <akim@epita.fr>
13319 * lib/autom4te.in (Autoreconf-preselections): Trace AC_CONFIG_AUX_DIR.
13320 * bin/autoreconf.in (autoreconf_current_directory): Create the
13321 AUX_DIR if needed, for sake of automake --add-missing etc.
13322 Suggested by Alexandre Duret-Lutz.
13324 2003-10-03 Akim Demaille <akim@epita.fr>
13326 * configure.ac: Quotation and formatting changes.
13327 (EMACS): Don't set it if it is not recent enough to support

13373 Problem reported by Lars J. Aas in
13374 <http://mail.gnu.org/archive/html/autoconf/2003-07/msg00042.html>.
13375 (_AS_MKDIR_P_PREPARE): Change "rm -fr ./-p" to the more-conservative
13376 "test -d ./-p && rmdir ./-p". Suggested by Andreas Schwab in:
13377 http://mail.gnu.org/archive/html/autoconf-patches/2003-09/msg00039.html
13379 2003-09-26 Akim Demaille <akim@epita.fr>
13381 * lib/autoconf/status.m4 (_AC_OUTPUT_COMMANDS): Make sure the
13382 directory for AC_CONFIG_COMMANDS' first argument exists.
13383 This makes valid the invocation of _AC_SRCPATH that follows.
13384 Reported by Eric Sunshine.
13385 * doc/autoconf.texi (Configuration Commands): Adjust.
13387 2003-09-26 Akim Demaille <akim@epita.fr>
13389 * bin/autoscan.in (Autom4te::FileUtils): Use it for find_file.
13390 Reported by Ralf Corsepius.
13392 2003-09-26 Akim Demaille <akim@epita.fr>
13394 * lib/autoconf/general.m4 (AC_HELP_STRING): Don't overquote the
13396 Actually, use AU_ALIAS.
13399 2003-09-26 Paul Eggert <eggert@twinsun.com>
13401 * lib/m4sugar/m4sh.m4 (_AS_MKDIR_P_PREPARE): If mkdir -p . fails,
13402 rm -fr ./-p to remove junk left behind on NextStep and OpenStep.
13403 Problem reported by Eric Sunshine in:

13408 The test suite are sometimes assigning timings incorrectly.
13409 Reported by Henk Krus.
13410 Diagnosed by Nicolas Joly.
13412 * lib/autotest/general.m4 (AT_CLEANUP): Rename AT_help as
13414 Instead of making AT_help a sequence of assignments to grow
13415 $at_help_all, just make AT_help_all be the growing contents of
13416 $at_help_all, and make a single assignment in...
13418 (at_times_skip): Flip the meaning and rename as...
13419 (at_times_p): this.
13420 (AT_INIT): When summarizing the test that ran, remove
13421 $at_times_file after use, and check it is present before trying to
13424 2003-09-25 Akim Demaille <akim@epita.fr>
13428 * bin/Makefile.am (edit): Handle '@configure_input@'.
13429 (autoconf, autoheader, autom4te, autoreconf, autoscan, autoupdate)
13430 (ifnames): chmod -w.
13431 * tests/wrapper.as (AUTOCONF, AUTOM4TE, ): Point to tests/
13432 executables, not bin/ executables! Otherwise all the magic needed
13433 to find non installed files is turned off. This caused a failure
13434 of test 40 and 41 that ran aclocal 1.8 which in turn ran autom4te
13435 as found in its environment (sent by tests/autoreconf): pointing
13436 to bin/autom4te that could not find its files.
13437 * tests/mktests.sh: Force the replacement of generated files, for
13438 the sake of "mv" program that are interactive when overwriting a
13440 * config/install-sh: Upgrade from CVS Automake.
13442 2003-09-23 Paul Eggert <eggert@twinsun.com>
13444 * doc/autoconf.texi (Limitations of Builtins): Document test -h
13445 versus test -L issues.
13447 2003-09-23 Daniel Jacobowitz <drow@mvista.com> and
13448 Paul Eggert <eggert@twinsun.com>
13450 Trivial change to support GCC's configuration procedure.
13451 * lib/autoconf/c.m4 (AC_PROG_CPP_WERROR): New macro.
13452 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): Don't warn
13453 about inconsistency if the preprocessor is set to give errors for

13488 2003-09-10 Akim Demaille <akim@epita.fr>
13490 * tests/fortran.at (GNU Fortran 77): Also exercise AC_FC_SRCEXT
13491 and AC_FC_FREEFORM.
13492 * tests/mktests.sh: Skip AC_FC_SRCEXT.
13493 * lib/autoconf/fortran.m4 (AC_FC_SRCEXT, AC_FC_FREEFORM): Likewise.

13529 2003-09-04 Akim Demaille <akim@epita.fr>
13531 * tests/mktests.sh (ac_exclude_list): Add AC_FC_FUNC.
13533 2003-09-02 Steven G. Johnson <stevenj@alum.mit.edu>
13535 Add support for newer Fortran dialects. The F77 interface is
13536 unchanged, and continues to support Fortran 77. New FC macros
13537 correspond to all the old F77 macros, with output variables FC,
13538 FCFLAGS, and FCLIBS. AC_PROG_FC defaults to picking the newest
13539 available dialect, but older dialects can be specified. There are
13540 new macros AC_FC_SRCEXT to set the source extension, and
13541 AC_FC_FREEFORM to accept free-form source files.
13543 * lib/autoconf/c.m4 (_AC_LANG_PREFIX(C), _AC_LANG_PREFIX(C++)):
13545 (AC_LANG_PROGRAM(C)): Invoke _AC_LANG_PROGRAM_C_FC_HOOKS if defined.

13562 Rewrite in terms of the above.
13563 (_AC_PROG_F77_G, _AC_PROG_F77_V_OUTPUT, _AC_PROG_F77_V): Remove.
13564 * lib/autoconf/lang.m4 (_AC_LANG_PREFIX): New macro.

13578 * tests/local.at: Require 2.57.
13579 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): Don't m4_default the arguments that
13580 are defaulted by AT_CHECK anyway.
13581 Use AT_CHECK_AUTOM4TE.

13657 Use &verb, not &verbose.
13659 2003-08-21 Akim Demaille <akim@epita.fr>
13661 * bin/autoheader.in (&parse_args): Use &parse_warnings and
13663 ($help): Use Autom4te::ChannelDefs::usage.
13664 * bin/autoscan.in: Use Autom4te::ChannelDefs.
13665 * lib/Autom4te/General.pm: Don't export error: you don't own it.
13667 2003-08-21 Akim Demaille <akim@epita.fr>
13669 First stab at preserving warnings between calls to autom4te,
13670 including when the cache is used.
13672 There are still several issues: (i) there are too many runs of m4
13673 (one for include, one for warnings, and some more), (ii) warnings
13674 spreading on several lines are not handled gracefully, (iii) the
13675 code meant to have the call stack display for errors does not work
13676 (its handling should move from m4 to autom4te).
13678 * bin/autom4te.in Autom4te::Channels, Autom4te::ChannelDefs):
13680 (@preselect): Add m4_warn.
13681 ($exit_status): Remove, use $exit_code.
13682 ($help): Use Autom4te::ChannelDefs::usage.
13683 (&handle_m4): No longer define the m4_warnings.
13684 At each run, extract and report the warnings.
13685 Always cache the result, including if the exit status is on
13686 failure, since if nothing changes, we should result in the same
13687 failure, hence we can use the cache.
13688 * lib/m4sugar/m4sugar.m4 (m4_warning_ifelse, _m4_warning_ifelse)
13689 (_m4_warning_error_ifelse, __m4_warning_error_ifelse, _m4_warn):
13691 (m4_warn): Redefine as a do-nothing: it is its invocation that
13692 matters, as warnings are now reported via traces.
13693 * lib/autoconf/general.m4 (AC_DIAGNOSE): Don't make it a copy of
13694 the contents of m4_warn: make it _call_ m4_warn, so that tracing
13695 the latter reveals calls to the former.
13699 * tests/m4sugar.at (m4@&t@_warn): Use existing warning categories.

13737 (&xsystem, &contents): Remove, since they are exported by...

13827 -lcrt1.o, for OS X. (trivial change)

13831 * lib/autoconf/c.m4 (AC_C_INLINE): Wrap the '#define inline ...'
13832 inside '#ifndef __cplusplus'. Problem reported by

13838 'long', not 'int', for benefit of Sun's recent C++ compilers
13839 (trivial change). See:
13840 http://mail.gnu.org/archive/html/autoconf-patches/2003-07/msg00007.html

13856 From Gareth McCaughan.
13858 2003-06-23 Akim Demaille <akim@epita.fr>
13860 * lib/autotest/general.m4 (AT_INIT): Report a single config.log,
13861 not all of them. This fixes 1. the fact that when testing
13862 Autoconf there are many many config.log, 2. the incorrect use of
13863 top_srcdir to find config.log.
13864 Don't mix the detailed output of failed test with the summary of
13865 failures. Rather, append detailed log afterwards.
13867 2003-06-23 Akim Demaille <akim@epita.fr>
13869 * tests/local.at (AT_CHECK_CONFIGURE): Adjust to the verbose being
13870 always run: output config.log on $at_group_log.
13872 2003-06-23 Akim Demaille <akim@epita.fr>
13874 * tests/torture.at (#define header templates): Don't use quotes in

13928 (AT_INIT): Support for expected failures.
13930 2003-06-02 Akim Demaille <akim@epita.fr>

13939 2003-05-28 Paul Eggert <eggert@twinsun.com>
13941 * NEWS, doc/autoconf.texi (Particular Functions),

13943 is the inverse of localtime.

13947 * lib/Autom4te/General.pm (END): Print diagnostics to STDERR.
13948 (handle_exec_errors): New function. Work around $! being
13949 altered by WEXITSTATUS.
13950 (xqx, xsystem): Use handle_exec_errors.
13952 2003-05-23 Alexandre Duret-Lutz <adl@gnu.org>
13954 * lib/Autom4te/General.pm (END): Rewrite exit code processing.
13955 Do not call `_exit()', simply modify `$?'.
13956 (xsystem): Reset $! before running system, and check it afterward.
13957 * tests/tools.at (autoupdating AC_PREREQ): Expect exit status
13958 63 for version mismatches.
13960 2003-05-23 Akim Demaille <akim@epita.fr>
13962 * lib/autoconf/status.m4: Prefer "TAB-SP" to "SP-TAB", because of
13963 Emacs' dangerous whitespace.el behavior (smashing "useless" spaces in
13964 the middle of a line).
13965 * lib/m4sugar/m4sugar.m4: Likewise.
13966 Remove useless spaces in comments.
13968 2003-05-23 Akim Demaille <akim@epita.fr>
13970 * lib/m4sugar/m4sugar.m4 (m4_version_prereq): Failure causes an
13971 exit 63, so that we (or Automake's "missing") can tell the
13972 difference with a plain failure.
13973 * doc/autoconf.texi (Notices): Adjust.
13975 2003-05-23 Akim Demaille <akim@epita.fr>

13979 White spaces cleanup.
13981 2003-05-22 Jim Meyering <jim@meyering.net>
13982 Paul Eggert <eggert@twinsun.com>
13984 * lib/autoconf/c.m4 (_AC_PROG_CXX_EXIT_DECLARATION):
13985 Remove `#include <stdlib.h>' from the list; we should never
13986 make confdefs.h include <stdlib.h> or <cstdlib>, because the
13987 resulting namespace pollution would cause other tests to fail.
13988 Configure scripts run with some older versions of g++ and HP's
13989 aCC would fail due to such an #include. Problems reported by
13990 Matthew Mueller in <http://bugs.debian.org/120704> and by
13992 <http://mail.gnu.org/archive/html/autoconf/2003-05/msg00063.html>.
13993 In the test, use the test declaration before including <stdlib.h>,
13994 as that's closer to how it'll be used.
13996 2003-05-23 Akim Demaille <akim@epita.fr>
13998 * doc/autoconf.texi (Header Portability): ucred.h.
14001 2003-05-22 Paolo Bonzini <bonzini@gnu.org>
14003 Overhaul Autotest's logging: generate separate log files
14004 in testsuite.dir/NNN/testsuite.log, and append them to
14005 testsuite.log instead of re-running the test verbosely.
14007 * lib/autotest/general.m4 (AT_INIT): Use a single redirected
14008 file descriptor, write 0 to at_status_file instead of setting
14009 at_status=0, initialize some new variables (at_status_file,
14010 at_group_log, at_suite_log, at_tee_pipe). Remove the cruft
14011 to rerun the tests, instead append the at_group_log to the
14012 at_suite_log when a test fails.
14013 (AT_SETUP): pipe the test case's output into at_tee_pipe,
14014 with the AS_MESSAGE_LOG_FD redirected to stdout.
14015 (AT_CLEANUP): save the output status in $at_status_file
14016 and restore it, redirect the AS_MESSAGE_LOG_FD back to
14017 its original place.
14018 (AT_CHECK): since tests are run with a redirected stdout,
14019 and used to be re-run in verbose mode, turn some $at_verbose
14020 into echo, and don't redirect the output of testing stdout
14023 * lib/autotest/autoconf.texi (testsuite Scripts): Update
14024 the name of the debugging directory and information about
14027 2003-05-22 Paolo Bonzini <bonzini@gnu.org>

14144 2003-05-06 Akim Demaille <akim@epita.fr>
14146 Don't try to be smart with aclocal 1.8+ because (i) aclocal no
14147 longer updates aclocal.m4 if useless, (ii) if a file m4_included
14148 by aclocal.m4 is changed it might require the importing of another
14149 m4 extension file, i.e., aclocal must be run.
14151 * bin/autoreconf.in (&run_aclocal, $aclocal_supports_force): New.
14152 (&parse_args): Use --force with aclocal if required and supported.
14153 (&autoreconf_current_directory): Use &run_aclocal.

14166 2003-04-29 Derek Price <derek@ximbiot.com>
14168 * lib/autotest/general.m4 (AT_KEYWORDS): Don't use a comma as the

14170 (AT_CLEANUP): Add `;' to end of at_help_all.
14171 (AT_INIT): Allow --keywords to be specified more than once. When
14172 grepping $at_help_all for keywords, use the field and keyword
14173 seperators to ensure a complete keyword match. Alter at_prev handling
14174 to support the new --keywords behavior.
14176 2003-04-27 Karl Berry <karl@freefriends.org>
14178 * doc/autoconf.texi: Make the dir entries in the autoconf manual
14179 align better with others. I also made some of the individual
14180 entries on one line, for brevity and to make it easier for me to
14181 sort my dir-example file in the Texinfo distribution :).

14248 header causes problems.
14250 2003-03-28 Akim Demaille <akim@epita.fr>
14252 * tests/torture.at (Configuring subdirectories): Require aclocal
14253 1.4, otherwise the test fails, as it does support configure.ac.

14276 * lib/autoconf/general.m4 (AC_ARG_VAR): Use AS_HELP_STRING instead of
14277 obsolete AC_HELP_STRING.
14278 (AC_HELP_STRING): AU_DEFUN to...
14279 * lib/m4sugar/m4sh.m4 (AS_HELP_STRING): ...here.
14280 * tests/m4sh.at (AS_HELP_STRING): New test.
14282 * tests/acgeneral.at: Regenerated.
14284 2003-03-26 Derek Price <derek@ximbiot.com>
14286 * lib/autotest/general.m4: s/DEFAULT/DEFAULTS/ since it makes more
14287 sense. Verbosify the diversion definitions comment.

14327 (Automake): Automake 1.5+ no longer requires special tools to be
14328 present on the developer's host.
14330 2003-02-26 Richard Dawe <rich@phekda.freeserve.co.uk>
14332 * bin/autoheader.in (BEGIN): For DJGPP SHELL may not be set
14333 to a shell that can handle redirection or quoting correctly.

14339 * bin/autoupdate.in (BEGIN): Likewise.
14340 * bin/ifnames.in (BEGIN): Likewise.
14342 * bin/ifnames.in: Add final newline to help and version messages.
14344 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Translate colons,
14345 to cope with DOS-style absolute paths, when constructing
14348 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS, _AC_OUTPUT_FILES):
14349 When constructing paths with IFS=:, quote the path. If we're
14350 constructing a DOS-style absolute path, we don't want to split it
14353 * tests/atspecific.m4 (AT_CHECK_CONFIGURE): Fix typo
14356 2003-02-25 Pavel Roskin <proski@gnu.org>

14364 2002-09-01 patch by replacing "test -n" with "test -z".
14365 This fixes a bug found by Jeff Painter and reported by Tom Epperly in
14366 <http://mail.gnu.org/archive/html/autoconf/2003-02/msg00139.html>.
14368 * doc/autoconf.texi (Shell Substitutions): test -n -> test -z,
14369 to fix a mismatch between example and discussion.

14373 * doc/autoconf.texi (Limitations of Builtins): Add notes on printf
14374 format starting with "-".
14376 2003-02-20 Alexandre Duret-Lutz <adl@gnu.org>
14378 * doc/autoconf.texi (Limitations of Make): `foo=bar make -e'
14379 is not portable inside Makefile.
14381 2003-02-20 Akim Demaille <akim@epita.fr>
14383 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): When
14384 compiler says yeah, but preproc says nope, compiler is right.
14385 Conversely, prompt the reader to send a bug report to the
14386 maintainers of the package, not of Autoconf.
14388 2003-02-20 Klee Dienes <kdienes@apple.com>
14390 * bin/autoreconf.in (autoreconf_current_directory): Properly
14391 handle an empty aclocal.m4.

14396 $ac_prefix_program.
14399 2002-12-23 Paul Eggert <eggert@twinsun.com>
14401 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Define $1 to an
14402 innocuous variant befor including <limits.h> or <assert.h>. This
14403 works around a bug reported by Albert Chin: HP-UX 11i
14404 (and earlier versions) have a <limits.h> that declares
14405 gettimeofday and many other functions.
14407 2002-12-03 Paul Eggert <eggert@twinsun.com>
14411 * NEWS, configure.ac: Update version.
14413 * doc/fdl.texi: Upgrade to FDL version 1.2.
14415 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Use the function f
14416 nontrivially in main's body, so that f's external declaration is
14417 not optimized away in AIX. This should fix the bug reported by
14419 <http://mail.gnu.org/pipermail/autoconf/2002-November/014508.html>.
14421 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C),
14422 _AC_PROG_PREPROC_WORKS_IFELSE): Use <limits.h> if __STDC__ is
14423 defined, to support freestanding compilers. This should fix the
14424 bug reported by Momchil Velkov in
14425 <http://mail.gnu.org/pipermail/autoconf/2002-November/014490.html>.
14427 * doc/autoconf.texi (Obsolete Macros): Fix typos (insert empty
14428 arg, AC_DEFINE -> AC_DEFINE_UNQUOTED) in documentation for
14429 obsolete AC_CHECK_TYPE. The missing empty arg was reported

14431 <http://mail.gnu.org/pipermail/autoconf-patches/2002-December/008830.html>.
14433 * Makefile.maint (www-gnu): New macro.
14434 (standards.texi-url_prefix, make-stds.texi-url_prefix): Use it, as

14440 \(.*\) match is too long and there is something more to be checked.
14441 <http://mail.gnu.org/pipermail/autoconf/2002-November/014524.html>

14459 Update from masters.
14461 2002-11-14 Akim Demaille <akim@epita.fr>
14463 * Makefile.maint: Sync with Bison, i.e.:
14464 (po-check): Scan .l and .y files instead of the
14465 .c and the .h files that they generate. This fixes the bug
14466 reported by Tim Van Holder in:
14467 <http://mail.gnu.org/pipermail/bison-patches/2002-November/001352.html>
14468 Look for N_ as well as for _. Try to avoid matching #define for
14472 2002-11-14 Akim Demaille <akim@epita.fr>
14474 * doc/autoconf.texi (C Compiler): Compiling several files at once.
14475 From Paul Eggert and Albert Chin-A-Young.
14477 2002-11-14 Akim Demaille <akim@epita.fr>
14479 * doc/autoconf.texi (C Compiler): Solitary backslashes.
14480 From Paul Eggert and Albert Chin-A-Young.
14482 2002-11-14 Kevin Ryde <user42@zip.com.au>
14484 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Initialize f=$1 rather
14485 than assigning in main, to avoid HP cc +O3 optimizing it away.
14487 2002-11-12 Peter Eisentraut <peter_e@gmx.net>
14489 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Add -q
14490 option. Process --recheck after parsing all options. Pass -q
14491 option to configure on --recheck.
14492 (AC_OUTPUT): Pass -q from configure to config.status.
14493 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Strip -q from
14494 arguments to record.
14495 * doc/autoconf.texi (config.status Invocation): Document
14496 config.status -q option.
14498 2002-11-07 Alexandre Duret-Lutz <adl@gnu.org>
14500 * bin/autoscan.in (scan_file): Scan Makefile.am too. Ignore
14501 Makefile.in if Makefile.am exists.
14502 (output): Strip `.am' from Makefiles. Don't
14503 output AC_CONFIG_FILES if no Makefiles were found.

14523 Reported by Ezra Peisach.
14525 2002-11-05 Akim Demaille <akim@epita.fr>
14527 * lib/autoconf/autoheader.m4 (_AH_TEMPLATE_OLD, _AH_VERBATIM_OLD):
14529 We _have_ to stop using the old compatibility scheme that tried to
14530 avoid useless backslashes because Libtool 1.4.3 contains a
14531 AC_DEFINE([error_t], [int],
14532 [Define to a type to use for \`error_t' if it is not
14533 otherwise available.])
14534 We _have_ to quote the single quote and backslashes with \. The
14535 old compatibility scheme saw that ` was backslashed, and therefore
14536 did not quote the single quote. Hence before this patch, Autoconf
14537 was not compatible with Libtool.
14539 2002-11-04 Paul Eggert <eggert@twinsun.com>
14541 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Set the following variables,

14556 * bin/autoreconf.in (&autoreconf_current_directory): New, extracted
14558 (&autoreconf): here.
14559 ($help, $make, &parse_args, &autoreconf_current_directory):
14561 * doc/autoconf.texi (autoreconf Invocation): Adjust.
14563 2002-10-31 Bruno Haible <bruno@clisp.org>

14579 2002-10-31 Akim Demaille <akim@epita.fr>
14581 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Use and display
14582 `$(MAKE)' instead of '${MAKE}' to emphasize that we refer to the
14583 Make variable, not a shell variable.
14584 Suggested by Bruno Haible.
14586 2002-10-31 Akim Demaille <akim@epita.fr>
14588 * bin/autom4te.in (load_configuration): Reject #args out of any
14591 2002-10-31 Akim Demaille <akim@epita.fr>
14593 * lib/autoconf/general.m4 (_AC_MSG_LOG_CONFTEST): New.
14594 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE, _AC_LINK_IFELSE)
14595 (_AC_RUN_IFELSE): Use it.
14596 * lib/autoconf/lang.m4 (_AC_COMPILER_OBJEXT):

14605 Suggested by Tim van Holder.
14607 2002-10-29 Paul Eggert <eggert@twinsun.com>
14609 * doc/autoconf.texi (Particular Functions): AC_FUNC_MALLOC and
14610 AC_FUNC_REALLOC check for compatibility with glibc, not POSIX.
14611 Problem reported by Bruno Haible.
14613 2002-10-29 Akim Demaille <akim@epita.fr>
14615 * doc/autoconf.texi (Header Templates): Put also in words what the
14616 pictures says to assist free style readers.
14617 (Customizing autom4te): s/--cache=/--cache /.
14619 2002-10-29 Akim Demaille <akim@epita.fr>
14621 * lib/autoconf/functions.m4 (_AC_FUNC_VFORK): Include stdlib.h and
14623 sparc_address_test returns void.
14624 Use it with an argument, as prototyped.
14627 2002-10-29 Akim Demaille <akim@epita.fr>
14629 * doc/autoconf.texi (Subdirectories): Cygnus dirs have

14991 * bin/autoreconf.in (&autoreconf): Run autopoint before the first
14992 aclocal invocation, as Gettext macros might not be visible to

15199 * bin/autoreconf.in: Don't use Cwd::chdir, since in its internals
15200 (chdir_init) might hang when stat'ing mounted directories.
15201 Reported by Vance Shipley.
15203 2002-09-12 Akim Demaille <akim@epita.fr>
15205 * bin/autoscan.in (&parse_args): Pass a reference to the lists, not
15208 2002-09-12 Akim Demaille <akim@epita.fr>
15210 * doc/autoconf.texi (Defining Symbols): Present two different
15211 prototypes for AC_DEFINE and AC_DEFINE_UNQUOTED to emphasize the
15212 difference between 1 argument calls, and 2-3 argument calls.
15214 2002-09-12 Peter Eisentraut <peter_e@gmx.net>
15216 * doc/autoconf.texi: Review grammar and punctuation.
15218 2002-09-11 Paul Eggert <eggert@twinsun.com>
15220 * doc/autoconf.texi: Fix minor formatting, spelling, and
15222 (Defining Symbols): Explain that AC_DEFINE(var) defaults to 1, but
15223 AC_DEFINE(var,,description) does not; and the AC_DEFINE(var) case
15226 2002-09-11 Akim Demaille <akim@epita.fr>
15228 * doc/autoconf.texi (Questions): Rename as...
15230 (Defining Directories): New.
15232 2002-09-09 Akim Demaille <akim@epita.fr>
15234 * doc/autoconf.texi (Making testsuite Scripts): Update.
15235 Suggested by Nishio Futoshi.
15237 2002-09-09 Koji Arai <JCA02266@nifty.ne.jp>
15239 * doc/autoconf.texi (Making testsuite Scripts): Use `@@' where a
15240 plain `@' is wanted.
15242 2002-09-09 Akim Demaille <akim@epita.fr>
15244 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Keep the
15245 `duplicates', since the algorithm was too naive and could keep
15246 `--prefix=1 --prefix=2 --prefix=1' as `--prefix=1 --prefix=2', and
15247 keep `--prefix foo --prefix bar' as `--prefix foo bar'.
15248 Reported by Ralf Corsepius.
15249 * tests/torture.at (Configuring subdirectories): Exercise these
15252 2002-09-09 Akim Demaille <akim@epita.fr>
15254 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Use $srcdir when
15255 looking for a replacement file.
15256 * lib/autoconf/general.m4 (AC_CHECK_DECLS): Check that the
15257 directory is relative.
15258 * doc/autoconf.texi (Generic Functions): Clarify the replacement
15259 directory definition.
15260 Reported by Andreas Schwab and Jim Meyering.
15262 2002-09-06 Akim Demaille <akim@epita.fr>
15264 * doc/autoconf.texi (Setting Output Variables): Clarify what
15265 precious variables are.
15266 Suggested by Pontus Skoeld.
15268 2002-09-05 Akim Demaille <akim@epita.fr>
15270 * bin/Makefile.am (autoconf, autoheader, autoreconf, autoupdate)
15271 (ifnames, autoscan, autom4te): Since we don't only depend on
15272 configure.ac variables (such as VERSION etc.), but also on prefix
15273 and so forth, depend on Makefile, not configure.ac.
15274 Reported by Alexandre Duret-Lutz.
15275 * doc/autoconf.texi (Installation Directory Variables): Adjust.
15277 2002-09-05 Kevin Ryde <user42@zip.com.au>
15279 * doc/autoconf.texi (Limitations of Make): HP-UX trailing backslashes
15280 doesn't seem to be confined to ia64, just say "some versions".
15282 2002-09-04 Akim Demaille <akim@epita.fr>
15284 * Makefile.am, doc/Makefile.am: Remove pdf targets, handled by
15286 * Makefile.am (maintainer-clean-local): Remove.
15287 (MAINTAINERCLEANFILES): Remove COPYING.
15289 2002-09-03 Paul Eggert <eggert@twinsun.com>
15291 * doc/autoconf.texi (Configuration Commands): Remove obsolete
15292 example for AC_CONFIG_COMMANDS_PRE. Problem reported by Marcus
15295 2002-09-03 Akim Demaille <akim@epita.fr>
15297 * configure.ac: Bump to 2.53d.
15298 * Makefile.am (AUTOMAKE_OPTIONS): Require 1.6c, i.e., CVS Automake
15299 as of today, on Automake's team suggestion.
15301 2002-09-03 Akim Demaille <akim@epita.fr>
15305 2002-09-02 Akim Demaille <akim@epita.fr>
15307 * bin/autom4te.in (parse_args): Don't honor AUTOM4TE_PATH and
15309 * configure.ac: Disable SITE_MACRO_DIR.
15311 2002-09-02 Jim Meyering <meyering@lucent.com>
15313 * doc/autoconf.texi (AC_SYS_POSIX_TERMIOS): Reflect renaming: s/am/ac/,
15314 i.e., change am_cv_sys_posix_termios to ac_cv_sys_posix_termios.
15315 Also, tweak grammar: s/make sure to/be sure to/.
15317 2002-09-02 Paul Eggert <eggert@twinsun.com>
15319 * doc/autoconf.texi (Limitations of Builtins): Explain why logical
15320 directory names are generally preferable to physical names.
15322 2002-09-02 Akim Demaille <akim@epita.fr>
15324 * lib/Autom4te/General.pm (&update_file): s/die/error/.
15325 Reported by Raja R. Harinath.
15326 * bin/autoheader.in, bin/autoreconf.in, bin/autoscan.in,
15327 * bin/autoupdate.in: Use error instead of die.
15329 2002-09-01 Paul Eggert <eggert@twinsun.com>
15331 * tests/mktests.sh (ac_exclude_egrep, au_exclude_egrep): Use
15332 ordinary shell concatenation rather than echo+tr+sed command that
15333 runs afoul of a long-line-related sed bug in Solaris 8.
15335 * bin/autoheader.in (parse_args): --warning -> --warnings.
15337 * bin/autoconf.as: Work even if "ls" outputs "FOO not found" to
15338 stdout, as traditional "ls" does.
15339 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT,
15340 _AC_COMPILER_EXEEXT_O): Likewise.
15341 * doc/autoconf.texi (Limitations of Usual Tools): Add "ls".
15343 * bin/autoconf.as: Add --prepend-include option. This patch was
15344 applied to bin/autoconf.in in the 2002-07-17 patch by Mark D. Roth,
15345 but bin/autoconf.in is generated automatically from bin/autoconf.as.
15347 * bin/autoconf.in, configure: Regenerate.
15349 * doc/autoconf.texi (Special Shell Variables): Mention
15350 ENV, MAIL, MAILPATH, PS1, PS2, PS4. Index PWD.
15352 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Unset ENV, MAIL,
15353 MAILPATH and set PS1, PS2, PS4 to default values, to work
15354 around bug in pre-3.0 UWIN ksh reported by Bruce Lilly.
15355 For LC_ALL etc, first try to set to "C" as POSIX requires and as
15356 the Autoconf documentation specifies; fall back to "unset" only if
15357 this fails. Use a shell for-loop for this rather than an m4 loop,
15358 to shorten the output script.
15360 2002-08-30 Paul Eggert <eggert@twinsun.com>
15362 * doc/autoconf.texi (Special Shell Variables): Mention POSIX
15363 1003.1-2001's requirements for CDPATH. Give a simpler workaround
15364 for the CDPATH problem. Document PWD.
15365 (Limitations of Builtins): Document the problem that "cd $foo" and
15366 "ls $foo" may refer to different directories in shells conforming
15367 to POSIX 1003.1-2001. Use PS1 rather than CDPATH for "unset"
15368 example, since the old example is now out of date.
15370 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Reject FOO if "cd
15371 FOO" and "ls FOO" talk about different directories; this catches
15372 problems when POSIX 1003.1-2001 "cd" fails due to symlink
15375 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Use AS_UNSET instead
15376 of rolling our own unset.
15377 (_AS_PREPARE): $as_unset CDPATH instead of AS_UNSETting it, since
15378 in practice we needn't worry about CDPATH if unset doesn't work.
15380 * Makefile.in, aclocal.m4, bin/Makefile.in,
15381 config/Makefile.in, doc/Makefile.in, lib/Makefile.in,
15382 lib/Autom4te/Makefile.in, lib/autoconf/Makefile.in,
15383 lib/autoscan/Makefile.in, lib/autotest/Makefile.in,
15384 lib/emacs/Makefile.in, lib/m4sugar/Makefile.in, man/Makefile.in,
15385 tests/Makefile.in: Regenerate with Automake 1.6.3.
15387 * config/config.guess, config/config.sub, config/mkinstalldirs:
15390 * configure: Regenerate with self.
15392 2002-08-30 Kevin Ryde <user42@zip.com.au>

15402 2002-08-29 Akim Demaille <akim@epita.fr>
15404 * lib/Autom4te/General.pm (&xqx): New.
15405 (&xsystem): Use WIFEXITED and WEXITSTATUS instead of decoding $? by
15406 hand, which is not portable.
15408 * bin/autom4te.in: Use them.
15409 Use &error instead of die.
15410 * tests/m4sugar.at (m4_warn, m4_require: circular dependencies):
15413 2002-08-17 Paul Eggert <eggert@twinsun.com>
15415 * lib/autoconf/fortran.m4 (AC_PROG_F77): Remove fc from the
15416 default list of compilers to try, since it was long ago superseded
15417 by the ksh fc builtin. Suggested by Steven G. Johnson.
15419 2002-07-31 Alexandre Duret-Lutz <duret_g@epita.fr>
15421 * doc/autoconf.texi (Invoking autom4te): End the option table,
15422 fixing a bug introduced by the previous patch.
15423 (Limitations of Make): Add a 'target lookup' subentry in the
15424 'VPATH' entry. Rewrite all `make' occurences as `@command{make}'.
15426 2002-07-29 Mark D. Roth <roth@feep.net>
15428 * bin/autom4te.in: Remove --include-envvar and --site-macro-subdir
15429 options and use $AUTOM4TE_PATH.
15430 * doc/autoconf.texi: Remove documentation of autom4te
15431 --include-envvar and --site-macro-subdir options and document
15432 use of $AUTOM4TE_PATH.
15433 * lib/autom4te.in: Remove --include-envvar and --site-macro-subdir
15434 arguments from each language section.
15436 2002-07-29 Paul Eggert <eggert@twinsun.com>
15438 * doc/install.texi: Include copyright symbol in copyright notice.
15440 * Makefile.am (MAKEINFO): Remove; it's a user-specified macro.
15442 (AM_MAKEINFOFLAGS): New macro.
15443 * doc/Makefile.am (MAKEINFO, AM_MAKEINFOFLAGS): Likewise.
15444 * Makefile.am (INSTALL): Use the new macros.
15445 Use -o rather than --output, since "missing" does not grok --output.
15447 2002-07-25 Alexandre Duret-Lutz <duret_g@epita.fr>
15449 * doc/autoconf.texi (Limitations of Make): Escaped newlines in
15450 comments do not always work. Never trust the exit status of
15453 2002-07-24 Kevin Ryde <user42@zip.com.au>
15455 * doc/autoconf.texi (Limitations of Make, Making testsuite Scripts):
15456 Untabify, since tabs are not enjoyed by texi2dvi and makeinfo.
15458 2002-07-23 Paul Eggert <eggert@twinsun.com>
15460 * lib/m4sugar/m4sh.m4 (_AS_PATH_SEPARATOR_PREPARE):
15461 Use PATH="/nonexistent;.", not PATH=".;.", as FreeBSD ksh2002
15462 apparently treats PATH="nonexistent" as if it contained ".".
15463 Bug reported by Stefan `Sec' Zehl.
15465 2002-07-22 Alexandre Duret-Lutz <duret_g@epita.fr>
15467 * doc/autoconf.texi (Limitations of Make): Mention the special

15515 ac_cv_func_fork_works before running _AC_FUNC_FORK, do it if the

15627 of the cache should not depend on the name under which autom4te

15686 * config/config.guess, config/config.sub, config/texinfo.tex:
15687 Update from masters.
15689 2002-05-29 Paul Eggert <eggert@twinsun.com>

15712 * NEWS, doc/autoconf.texi (Particular Types): Document it.
15713 * lib/autoconf/functions.m4 (_AC_FUNC_FNMATCH): Require it
15714 instead of AC_MBSTATE_T, which never existed.

15718 * doc/autoconf.texi (Hosts and Cross-Compilation): Specify the
15719 version of Autoconf that is discussed.
15721 2002-05-22 Paul Eggert <eggert@twinsun.com>
15723 * lib/autoconf/fortran.m4 (AC_PROG_F77): Remove cf77 and cft77
15724 from the default list of compilers to try. Suggested by
15726 * NEWS: Document the above.
15727 * doc/autoconf.texi (Fortran 77 Compiler): Don't suggest cf77.
15729 2002-05-17 Paul Eggert <eggert@twinsun.com>
15731 * lib/autoconf/types.m4 (AC_CHECK_MEMBER): Work correctly even if
15732 the member is itself an aggregate. Bug reported by Sergey Poznyakoff.
15733 This improves on an earlier suggestion by H. Peter Anvin.
15735 2002-05-16 Paul Eggert <eggert@twinsun.com>
15737 AC_FUNC_FNMATCH now tests only for POSIX compatibility.
15738 AC_FUNC_FNMATCH_GNU also tests for GNU extensions.
15739 Both macros now accept an optional source-dir arg.
15740 New macro AC_GNU_SOURCE to define _GNU_SOURCE.
15742 * NEWS: Document this.
15743 * doc/autoconf.texi (Particular Functions, UNIX Variants): Likewise.
15745 * lib/autoconf/functions.m4 (_AC_FUNC_FNMATCH): New macro.
15746 (AC_FUNC_FNMATCH): Use it. Test only for POSIX conformance,
15747 not for GNU extensions; this undoes part of the 2000-11-03 change,
15748 reverting to 2.13-compatible behavior.
15749 Add new optional argument DIR.
15750 (AC_FUNC_FNMATCH_GNU): New macro.
15752 * lib/autoconf/specific.m4 (AC_GNU_SOURCE): New macro.
15754 2002-05-08 Paul Eggert <eggert@twinsun.com>
15756 * lib/autoconf/headers.m4 (AC_HEADER_TIOCGWINSZ):
15757 Don't require AC_SYS_POSIX_TERMIOS. The test is unnecessary,
15758 and it causes a 'test' syntax error if it fails.
15759 Bug reported by Stephen Gildea.
15761 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
15762 If prototypes are supported, use them to check this at compile-time,
15763 instead of trying to check it at run-time. If we must do a run-time
15764 check, assume that setvbuf is standard when cross-compiling, as
15765 nonstandard setvbuf occurs only on ancient and unlikely hosts.
15766 Bug reported by Paul D. Smith.
15768 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Add optional
15769 argument specifying location of getloadavg.c. This removes a
15770 FIXME. This idea was taken from Jim Meyering's implementation in
15772 * doc/autoconf.texi (Particular Functions): Document this.
15773 Also, mention HAVE_NLIST_H rather than NLIST_STRUCT, since
15774 that's what the code does; this fixes a bug reported by
15777 2002-05-03 Akim Demaille <akim@epita.fr>
15779 * bin/autoreconf.in (autoreconf): Rewrite to use Gettext's
15780 autopoint instead of gettextize.
15781 ($uses_alocal): Rename as...
15782 ($uses_aclocal): this.
15783 * doc/autoconf.texi (autoreconf Invocation): Adjust.
15784 Suggested by Bruno Haible.
15786 2002-05-03 Akim Demaille <akim@epita.fr>
15788 * lib/m4sugar/m4sugar.m4 (m4_map_sep): New.
15790 2002-04-29 Paul Eggert <eggert@twinsun.com>
15792 * bin/autoreconf.in (autoreconf): Don't age aclocal.m4's input
15793 files to be 1 second older; just set them to be the same time.
15794 Also, sleep 1 second after the first aclocal, to work around
15795 problems with sub-second time stamps on the input files.
15797 2002-04-29 Thien-Thi Nguyen <ttn@gnu.org>
15799 * doc/autoconf.texi: Mention "set -e -x" lossage
15800 under node "Limitations of Builtins".
15802 2002-04-29 Akim Demaille <akim@epita.fr>
15804 * doc/install.texi: Better wording for setting variables when
15806 From Christian Cornelssen.
15808 2002-04-29 Akim Demaille <akim@epita.fr>
15810 * tests/m4sh.at (LINENO): If testsuite itself is rewritten because
15811 of lack of $LINENO support, then the test will compare the $LINENO
15812 in testsuite vs. the lineno in the test file. This is wrong, of
15814 Be sure to protect it.
15815 Reported by Patrick Welche.
15817 2002-04-25 Akim Demaille <akim@epita.fr>
15819 * doc/autoconf.texi (Obsolete Macros): Typo.
15820 Reported by Vladimir Volovich.
15822 2002-04-25 Akim Demaille <akim@epita.fr>
15824 * bin/autoreconf.in (autoreconf): Don't let aclocal.m4 be older
15825 than some of the input files, hence, on the second run of aclocal,
15826 if some of its input are younger, make them older.
15827 Suggested by Paul Eggert.
15829 2002-04-25 Akim Demaille <akim@epita.fr>
15831 * doc/autoconf.texi (Limitations of Usual Tools): sed and `!'.

15836 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Let ac_subst_files
15837 and ac_subst_vars be sh variables containing the list of
15838 AC_SUBST_FILES'ed and AC_SUBST'ed identifiers. Output them in the
15840 (_AC_INIT_PREPARE): Use them to log them.
15841 (_AC_SUBST, _AC_SUBST_SED_PROGRAM): Remove.
15842 (AC_SUBST, AC_SUBST_FILE): Instead of buliding the
15843 _AC_SUBST_SED_PROGRAM, store the list of output files/variables in
15844 _AC_SUBST_FILES and _AC_SUBST_VARS.
15845 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Adjust.
15847 2002-04-24 Akim Demaille <akim@epita.fr>
15849 * bin/autoreconf.in (autoreconf): Run automake after autoconf and
15850 autoheader, so that automake does not complain about a missing
15851 config.h.in that was to be created.
15853 2002-04-23 Akim Demaille <akim@epita.fr>
15855 * bin/autoheader.in (parse_args): --warning takes an argument.
15858 2002-04-22 Peter Eisentraut <peter_e@gmx.net>
15860 * lib/autoconf/general.m4 (_AC_RUN_IFELSE): Remove gmon.out

15905 Minor spelling and grammar fixes.
15907 * doc/autoconf.texi: Follow the outline suggested in the GNU
15908 Sample Texts sections of the Texinfo 4.2 manual. Most
15909 importantly, this makes sure that the copyright notices appear in
15910 all output formats. You probably need Texinfo 4.2 to generate

15939 * bin/autoupdate.in (handle_autoconf_macros): Honor AU_DEFUNs

15950 * doc/autoconf.texi (Shell Substitutions): Explain it.
15951 From Oliver Kiddle and Peter Stephenson.
15953 Have M4sh perform minimal shell sanitizing.
15955 * lib/m4sugar/m4sh.at (AS_SHELL_SANITIZE): Split the `_AS_PREPARE_*'
15957 (_AS_PREPARE): this new macro.

15962 Adjust Autoconf and Autotest.
15964 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Don't invoke
15965 AS_SHELL_SANITIZE, AS_INIT did it, but invoke AS_PREPARE.
15966 * lib/autotest/general.m4 (AT_INIT): Likewise.
15967 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
15968 Invoke _AS_PREPARE (not AS_PREPARE) in addition to
15971 Use this M4sh to generate Autoconf's shell scripts.
15973 * tests/wrapsh.as: New, precursor of wrapsh.in.
15974 * tests/Makefile.am: Include lib/freeze.mk to get the dependencies
15975 on Autotest and M4sh.
15976 ($(TESTSUITE)): Use $(autotest_m4f_dependencies).
15977 (wrapsh.in): New target.

15993 * doc/autoconf.texi (Systemology): Add link to Unix V7 online docs.
15994 (Portable Shell): Cross reference to Systemology.
15996 2002-04-05 Akim Demaille <akim@epita.fr>
15998 * bin/autoreconf.in (autoreconf): Be sure to accumulate the
15999 directories when descending in a SUBDIRS.

16002 2002-04-04 Andreas Schwab <schwab@suse.de>

16005 contains no literal separators.

16009 * lib/autoconf/status.m4 (_AC_CONFIG_FILE, _AC_CONFIG_HEADER)
16010 (_AC_CONFIG_COMMAND, _AC_CONFIG_LINK): New.
16011 Use dnl, not the KILL diversion.
16013 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_COMMANDS)
16014 (AC_CONFIG_LINKS): here.
16016 Don't use the KILL diversion, as it kills spurious output, which
16017 results in failures being hidden.
16018 Use m4_defn where appropriate.
16019 (AC_CONFIG_IF_MEMBER): Kill the real bug: a spurious parenthesis
16020 after the second argument.
16022 * lib/autom4te.in (Autoconf, Autotest, M4sh): Don't pass --warning
16023 syntax, as it is provided by M4sugar.

16088 2002-03-25 Alexandre Duret-Lutz <duret_g@epita.fr>
16090 * doc/autoconf.texi (Limitations of Make): Mention more issue
16091 about VPATH, overriding of macros in sub-makes, and handling of
16094 2002-03-21 Paul Eggert <eggert@twinsun.com>
16096 * doc/autoconf.texi (Here-Documents): Mention Solaris 8 dtksh
16097 problem with here-document buffer boundaries.
16099 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Unset ENV and BASH_ENV
16100 when reinvoking the shell, to work around problems with installers
16101 who put strange things like "cd" commands in their environments.

16126 (Limitations of Usual Tools): Add mkdir section.
16128 * lib/m4sugar/m4sh.m4 (_AS_MKDIR_P_PREPARE): New macro.
16129 (AS_MKDIR_P): Require it. Use mkdir -p if available, falling
16130 back on AS_DIRNAME to compute prefixes otherwise; this is
16131 roughly what mkinstalldirs does. That way, we need not have
16132 our own filename disassembler. The old disassembler did not
16133 work with Solaris 8 dtksh, which is ksh Version M-12/28/93d.
16135 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP):
16136 Create at_test_all by a series of assignments,
16137 not by a single assignment of a long string. The latter causes ksh
16138 version 11/16/88g to silently misbehave on OpenServer 5.0.6a,
16139 presumably because of a buffer overrun.
16141 2002-03-14 Paul Eggert <eggert@twinsun.com>
16143 * lib/autotest/general.m4 (at_times_skip):
16144 Renamed from at_times. Now a boolean.
16145 ksh93 Version M-12/28/93d doesn't like 'x=times; $x'; it
16146 says 'times: not found'.

16240 (Hosts and Cross-Compilation): this new section.
16241 * doc/install.texi (System Type): Ditto.
16242 * lib/autoconf/general.m4 (AC_CANONICAL_HOST): Explicitly state

16255 2002-03-04 Akim Demaille <akim@epita.fr>

16260 * lib/m4sugar/m4sugar.m4 (m4_quote, m4_dquote): Use $@ rather than
16261 $*. This is the n-th time I change my mind, but hopefully this is
16264 (m4_text_wrap): Use m4_foreach, which is finally correct _and_
16266 (m4_foreach_quoted, m4_car_quoted, _m4_foreach_quoted): Remove, as
16267 it was only a hack for m4_text_wrap.
16268 (m4_car2): Remove, replaced by...
16270 (_m4_foreach): Adjust.
16271 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Adjust, and use

16432 * lib/autotest/general.m4 (AT_INIT): Don't be ridiculous: adjust
16433 AUTOTEST_PATH *after* it was set.
16434 Don't put `.' in the PATH: the user should be precise and `./' if
16435 needed. In addition, given that the test suite does some `cd', if
16436 `.' is in the path, the `tested programs' sections will report
16437 programs found in the test suite's directory, while during the
16438 tests (performed in their own directory), these programs are no
16439 longer visible. In other words, the results is confusing and

16516 of PACKAGE_NAME, PACKAGE_TARNAME, PACKAGE_VERSION, PACKAGE_STRING,
16517 and PACKAGE_BUGREPORT from here...
16518 (_AC_INIT_DEFAULTS): to here, since it is unrelated to the
16520 (_AC_INIT_PREPARE): AC_DEFINE these symbols.
16521 * lib/autotest/general.m4: Use AT_PACKAGE_*, not PACKAGE_*.

16550 Suggested by Jonathan Kamens.

16663 This patch implements a `long double' suggestion by Oliver Kiddle.
16665 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C)): Make the array
16666 static, to catch errors if the value isn't known at compile-time
16667 and the compiler supports dynamic arrays. Change its name from
16668 `_array_' to `test_array' to avoid potential name clashes.
16669 (AC_C_LONG_DOUBLE): Make it a compile-time test, not a run-time
16670 test. Do not define HAVE_LONG_DOUBLE if `long double' is no
16671 better than double. Catch a bug in GCC 2.95.2 x86.

16681 2001-11-13 Akim Demaille <akim@epita.fr>
16683 * lib/autotest/general.m4 (AT_INIT): After having run the test
16684 group, go back to the initial directory, not to at_suite_dir.
16686 2001-11-13 Akim Demaille <akim@epita.fr>
16688 * tests/atspecific.m4 (AT_DATA_M4SUGAR, AT_DATA_M4SH)
16689 (AT_DATA_AUTOCONF): Also protect @&t@ from autom4te.
16690 (AT_CHECK_AUTOCONF, AT_CHECK_AUTOHEADER): Pass no --include
16692 (AT_CHECK_CONFIGURE): Use absolute paths.
16693 (_AT_CHECK_AC_MACRO): Create aclocal.m4 with AC_STATE_SAVE in it.
16694 The problem is still the old one: there is no means in M4 (that I
16695 know about) to create a defining macro, because there is no means
16696 to create `$1' etc., therefore, the defining macro ``swallows''
16697 all the arguments meant to the defined macro.
16699 2001-11-13 Akim Demaille <akim@epita.fr>
16701 * tests/atspecific.m4 (AT_DATA_AUTOCONF): New.
16702 (AT_CONFIGURE_AC): Output the definition of AC_STATE_SAVE in
16704 * tests/aclocal.m4: Remove, as it is no longer used.
16706 2001-11-13 Akim Demaille <akim@epita.fr>
16708 * lib/autotest/general.m4: Change `tests?' into `groups?' in
16709 variable names when referring to a single test group, or to
16710 `suite' when referring to the whole test suite.
16711 `at_last_test' is removed: m4 compute at_format itself.
16712 (at_stdout, at_stder1, at_stderr): New variables.
16713 (AT_CHECK): Use them.
16715 2001-11-13 Akim Demaille <akim@epita.fr>
16717 * lib/autotest/general.m4 (AT_INIT): Be sure to put `.', relative,
16719 Create `testsuite.dir/003/run' instead of `testsuite.003'.
16720 Do it as soon as a test fails, don't wait till the end of the test
16722 Don't remove $as_me.[0-9]*, since these files no longer exist.
16724 2001-11-13 Akim Demaille <akim@epita.fr>
16726 * tests/tools.at: Use absolute paths, since we are no longer run
16729 2001-11-13 Akim Demaille <akim@epita.fr>
16731 Now that tests are running in their own private dir, there is no
16732 need to list the files to remove at the end of tests groups.
16734 * lib/autotest/general.m4 (_AT_CLEANUP_FILE, AT_CLEANUP_FILES):
16735 (AT_data_files, at_data_files): Remove.
16736 (AT_CLEANUP, AT_DATA): Simplify.
16738 Remove the group dir if !debug && !failed.
16739 * tests/atspecific.m4: Adjust.
16741 2001-11-13 Akim Demaille <akim@epita.fr>
16743 Start a new layout for Autotest: `testsuite' creates
16744 `testsuite.dir' in which the at-check-line etc. files are to be
16745 found, and `testsuite.dir/003' where the test group 3 is run.
16747 * lib/autotest/general.m4 (AT_INIT): at_tests_dir,
16748 at_check_line_file, at_format, at_test_normalized, at_group_dir
16750 Create the directories.
16751 Use absolute paths for at- files.
16752 (AT_CHECK): Adjust.
16754 2001-11-11 Michael Matz <matz@kde.org>
16756 * m4sugar.m4 (_m4_foreach): Make it linear instead quadratic.
16758 (m4_car): Properly quote arguments.
16760 2001-11-13 Akim Demaille <akim@epita.fr>
16762 * tests/aclocal.m4 (AC_STATE_SAVE): s/LIBOBJS/LIB@&t@OBJS/ to cope
16763 with stricter rules on LIBOBJS.
16765 2001-11-12 Paul Eggert <eggert@twinsun.com>
16767 * lib/autoconf/c.m4 (AC_C_PROTOTYPES): Define __PROTOTYPES too.
16768 * doc/autoconf.texi (C Compiler): AC_C_PROTOTYPES now defines
16771 2001-11-12 Akim Demaille <akim@epita.fr>
16773 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT): Use AC_CHECK_FUNCS.
16775 2001-11-12 Akim Demaille <akim@epita.fr>
16777 * lib/autoconf/c.m4, lib/autoconf/fortran.m4,
16778 * lib/autoconf/functions.m4, lib/autoconf/general.m4,
16779 * lib/autoconf/headers.m4, lib/autoconf/libs.m4,
16780 * lib/autoconf/programs.m4, lib/autoconf/specific.m4,
16781 * lib/autoconf/types.m4: When invoking AC_DEFINE and friends,
16782 specify to what the macro should be defined (typically to 1).
16784 2001-11-12 Akim Demaille <akim@epita.fr>
16786 * lib/autoconf/functions.m4 (AC_FUNC_STRTOD): AC_SUBST POW_LIB.
16789 2001-11-12 Akim Demaille <akim@epita.fr>
16791 * lib/autoconf/programs.m4 (_AC_PROG_LEX_YYTEXT_DECL): Use
16792 AC_TRY_EVAL to run $LEX, not AC_TRY_COMMAND. This validates the
16793 definition used by Automake where LEX is +/- "${missing} lex" and
16794 `missing' itself contains variables.
16796 2001-11-12 Akim Demaille <akim@epita.fr>
16798 * lib/autotest/general.m4 (AT_INIT): Push KILL at the end.
16799 Now that M4sh pushes BODY, the comments were output at the end of
16802 2001-11-08 Akim Demaille <akim@epita.fr>
16804 * bin/autoreconf.in (&autoreconf): Run aclocal before tracing, so
16805 that we can trace macros from aclocal.m4.
16806 Trace AC_PROG_LIBTOOL, not AM_PROG_LIBTOOL, since the latter is
16807 obsoleted, and redirect to the former anyway.
16808 Reported by Ralf Corsepius.
16810 2001-11-08 Akim Demaille <akim@epita.fr>
16812 * bin/autoreconf.in (&autoreconf): AC_CONFIG_SUBIDRS are to be
16813 processed only if present.
16814 * tests/torture.at (Configuring subdirectories): Use autoreconf
16815 instead of successive calls to autoconf.
16816 Add a nonexistent subdirectory to exercise the patch above.
16817 Reported by Ralf Corsepius.
16819 2001-11-08 Kevin Ryde <user42@zip.com.au>
16821 * doc/autoconf.texi (Limitations of Usual Tools): Note HP-UX cc
16822 doesn't accept .S files.
16824 2001-11-07 Akim Demaille <akim@epita.fr>
16826 * lib/m4sugar/m4sugar.m4 (m4_pattern_forbid): Accepts $2.
16827 * lib/autoconf/general.m4 (AC_INTI): Forbid LIBOBJS.
16828 (_AC_LIBOBJ): s/LIBOBJS/LIB@&t@OBJS/.
16829 * bin/autom4te.in (warn_forbidden): New.
16830 (handle_output): Use it.
16831 Read m4_pattern_forbid with messages.
16833 2001-11-05 Akim Demaille <akim@epita.fr>
16835 * bin/autom4te.in (--normalize): Remove.
16836 * lib/autom4te.in: Adjust.
16838 2001-11-05 Akim Demaille <akim@epita.fr>
16840 * tests/Makefile.am (testsuite): Rename this target as...
16841 ($(TESTSUITE)): this.
16844 2001-11-05 Alexandre Duret-Lutz <duret_g@epita.fr>
16846 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): When removing
16847 the --prefix option, also remove it's argument.
16849 2001-11-05 Akim Demaille <akim@epita.fr>
16851 * doc/autoconf.texi (testsuite Invocation): Update.
16852 (Writing testsuite.at): Update.
16854 2001-11-03 Akim Demaille <akim@epita.fr>
16856 * doc/autoconf.texi: s/@code/@command/ where appropriate.
16858 2001-11-03 Akim Demaille <akim@epita.fr>
16860 * lib/Autom4te/General.pm: (&catfile, &canonfile)
16861 (&file_name_is_absolute): New, wrappers around routines from
16863 Use and export them.
16864 (&find_configure_ac): Optionally take a directory where to look at.
16865 * bin/autoreconf.in (&parse_args): Trim the configure.ac part of
16867 Default @ARGV to `.', not find_configure_ac.
16868 (&autoreconf): Argument is a directory.
16869 Trace AC_CONFIG_SUBDIRS and schedule the subdirs for autoreconf'ing.
16870 * doc/autoconf.texi (autoreconf Invocation): Update.
16872 2001-11-03 Akim Demaille <akim@epita.fr>
16874 * lib/Autom4te/General.pm (@export_vars, @export_subs)
16875 (@export_forward_subs): New.
16876 Add basename, dirname, and fileparse.
16878 * bin/autoreconf.in (&autoreconf): Fix call to fileparse.
16879 Don't look for aclocal flags if we already know aclocal is not
16881 Move aclocal.m4t only if it exists.
16882 Reported by Ezra Peisach.
16884 2001-11-03 Akim Demaille <akim@epita.fr>
16886 * bin/autoreconf.in (&parse_args): Work only on the configure.ac
16887 passed on command line, defaulting to ./configure.ac if present.
16888 (&maybe_autoreconf, File::Find): Remove, unused.
16889 (&autoreconf): If autoconf is not used, don't try to trace.
16891 2001-11-02 Akim Demaille <akim@epita.fr>
16893 * configure.ac: Bump to 2.52g.
16895 2001-11-02 Akim Demaille <akim@epita.fr>
16899 2001-11-02 Akim Demaille <akim@epita.fr>
16901 * config/config.guess, config/config.sub, doc/standards.texi:
16902 * config/lispdir.m4: Update from masters.
16903 * configure.ac: Bump to 2.52f.
16905 2001-11-02 Akim Demaille <akim@epita.fr>
16907 * bin/autoreconf.in (&autoreconf): Set `$aclocal_flags' to ''.
16908 Don't run aclocal when aclocal.m4 is not from aclocal.
16910 Don't run libtoolize and gettextize if --install is not given.
16912 2001-11-01 Paul Eggert <eggert@twinsun.com>
16914 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): _AS_CR_PREPARE needs to
16915 be invoked before _AS_LINENO_PREPARE.
16916 (_AS_LINENO_PREPARE): Use as_cr_digits and as_cr_alnum rather
16917 than character ranges.
16919 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Fix NLS before
16920 invoking AS_BASENAME. Set the locale variables to 'C' if
16921 possible, as POSIX requires this to get the traditional
16923 * doc/autoconf.texi (Special Shell Variables): Describe the above.
16925 2001-10-31 Paul Eggert <eggert@twinsun.com>
16927 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): Do not surround body
16928 with {}, as that triggers a bug in Bash 2.05.
16930 (_AS_LINENO_PREPARE): Use Sed rather than
16931 Awk. Fix the sed prepass to work even if there are multiple
16932 instances of $LINENO on the same line. Do not substitute for
16933 other variables like $LINENOT. Do not check file dates; such a
16934 check is unreliable on sufficiently fast machines, and removing
16935 the check makes the code simpler and more reliable. Check for
16936 output and chmod failures.
16938 * doc/autoconf.texi (Special Shell Variables): Document
16941 2001-10-31 Akim Demaille <akim@epita.fr>
16943 * tests/Makefile.am (atconfig): Remove this target, Automake
16946 2001-10-31 Akim Demaille <akim@epita.fr>
16948 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Do not
16949 AC_CONFIG_FILES(atlocal) as it means a file atlocal.in *must* be
16950 provided, while it is optional.
16951 * configure.ac: Adjust.
16953 2001-10-26 Paul Eggert <eggert@twinsun.com>
16955 * NEWS, README, configure.ac, lib/Autom4te/General.pm,
16956 lib/Autom4te/Struct.pm:
16957 Require Perl 5.005_03 instead of just 5.005, as some tests fail
16960 * doc/autoconf.texi (Special Shell Variables): Document some
16961 more LINENO gotchas, particularly with respect to the Awk+Sed hack.
16963 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): New macro.
16964 (_AS_LINENO_PREPARE): Use it instead of shell eval, since
16965 eval $LINENO is not portable in practice.
16967 2001-10-24 Akim Demaille <akim@epita.fr>
16969 * lib/Autom4te/General.pm (backname): New.
16971 2001-10-24 Akim Demaille <akim@epita.fr>
16973 * m4/: Remove, merged into...
16976 2001-10-23 Tim Van Holder <tim.van.holder@pandora.be>
16978 * doc/autoconf.texi (Shellology): Mention the problems with bash
16979 2.05's use of ANSI quoting in its `set' builtin.
16981 2001-10-22 Paul Eggert <eggert@twinsun.com>
16983 * lib/autoconf/functions.m4 (AC_FUNC_STRERROR_R):
16984 Rename ac_cv_func_strerror_r_works to ac_cv_func_strerror_r_char_p,
16985 and rename HAVE_WORKING_STRERROR_R to STRERROR_R_CHAR_P, since
16986 POSIX decided to standardize on the int flavor of strerror_r.
16987 Always do char* test, as there's no reason not to.
16988 Assign to a char* var, to catch strerror_r that returns int*.
16990 * doc/autoconf.texi (Particular Functions):
16991 Document the above changes. Also, document the fact that
16992 AC_FUNC_STRERROR_R defines HAVE_DECL_STRERROR_R.
16994 * NEWS: Mention HAVE_WORKING_STRERROR_R -> STRERROR_R_CHAR_P.
16996 2001-10-20 Akim Demaille <akim@epita.fr>
16998 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): The name of
16999 the executable was missing from the log.
17001 2001-10-20 Akim Demaille <akim@epita.fr>
17003 * lib/Autom4te/General.pm (&update_file): If destination is
17004 unchanged, remove the source.
17005 (&up_to_date_p): Don't be verbose, be debug.
17006 * bin/autoreconf.in: No longer support --m4dir.
17007 (&autoreconf): Display the full path of the configure.ac we are
17009 Trace it only once.
17010 Be sure to honor --force with gettextize.
17011 Always run aclocal.
17012 * doc/autoconf.texi: Adjust.
17014 2001-10-20 Akim Demaille <akim@epita.fr>
17016 * bin/autoheader.in ($localdir, $m4, $SIMPLE_BACKUP_SUFFIX):
17018 * bin/autoreconf.in (&autoreconf): Do not run gettextize when
17019 `intl' is already present, as it refuses unless --force.
17020 (&parse_args): Use -I, --include instead of the old Autoconf
17022 ($localdir, $autoconf_dir): Remove.
17024 (&maybe_autoreconf): New, to preserve $_ for File::Find.
17026 2001-10-19 Jens Petersen <petersen@redhat.com>
17028 * lib/autoconf/programs.m4 (AC_PROG_AWK): Prefer gawk to mawk.

17035 Don't mention `automatically' in addition to `generated'.
17036 * tests/torture.at (#define header templates): Adjust.
17038 2001-10-19 Akim Demaille <akim@epita.fr>
17040 * lib/emacs/autoconf-mode.el, lib/emacs/autotest-mode.el: In a
17041 comment, explain how to install automatic mode selection.
17044 2001-10-19 Ezra Peisach <epeisach@zif.mit.edu>
17046 * bin/autoreconf.in (autoreconf): Display the path to the
17047 configure.ac being studied.
17049 2001-10-18 Paul Eggert <eggert@twinsun.com>
17051 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Cast sizeof to unsigned
17052 long, to work around a bug in the HP C compiler version HP92453-01
17055 * lib/m4sugar/m4sh.m4 (AS_DIRNAME): Use 'dirname' if that works.
17056 (AS_BASENAME_EXPR): New macro.
17057 (AS_BASENAME_SED): Do not assume GNU sed semantics.
17058 (AS_BASENAME): Use 'basename' if that works; then try 'expr';
17059 and fall back on 'sed' only if the other two fail. This makes
17060 AS_BASENAME act more like AS_DIRNAME.
17061 (as_me): Shell-quote the argument of AS_BASENAME, in case $0
17062 contains white space.
17063 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR):
17064 Use AS_DIRNAME, since I think it's now DOS-friendly.
17065 * tests/m4sh.at (DIRNAME_TEST): New arg $3.
17066 Allow "dirname //FOO" to return either / or //, as POSIX allows
17069 2001-10-10 Akim Demaille <akim@epita.fr>
17071 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Recognize

17075 2001-10-10 Akim Demaille <akim@epita.fr>
17077 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N_PREPARE): m4_defun, not
17078 m4_define, since...
17079 (_AS_ECHO_N): AS_REQUIREs it.
17081 2001-10-10 Akim Demaille <akim@epita.fr>
17083 * lib/autoconf/general.m4 (_AC_INCLUDES_DEFAULT_REQUIREMENTS)

17115 (Syntax of the shell scripts): Don't.

17170 M4sugar peer, i.e., drop the `AC_PROVIDE_$1' broken marker.
17172 2001-10-08 Akim Demaille <akim@epita.fr>
17174 Use `add-log-current-defun-function' for ChangeLog creation.
17175 Suggested by Tom Tromey.
17177 * lib/emacs/autotest-mode.el (autotest-mode-map): New.
17178 (autotest-mode): Adjust.
17179 * lib/emacs/autoconf-mode.el (autoconf-mode-map): Modernize, map

17206 shell does not support LINENO, and if CONFIG_SHELL is unset or
17207 empty, and if we can find a shell that does support LINENO,
17208 then set CONFIG_SHELL to that shell and then re-execute
17209 ourselves with CONFIG_SHELL.
17211 2001-10-05 Paul Eggert <eggert@twinsun.com>
17213 * tests/Makefile.am (clean-local): Don't invoke $(TESTSUITE) if it
17214 doesn't exist. Remove *.tmp, as a .tmp file is created during the
17215 build of $(TESTSUITE).
17217 2001-10-05 Akim Demaille <akim@epita.fr>

17256 compatibility with POSIX shells.

17284 * lib/autoconf/status.m4 (AC_OUTPUT_MAKE_DEFS):
17285 Don't use nested parenthesization. This patch was originally
17286 suggested to bug-autoconf by Philippe De Muyter on 2000-05-28,
17287 but somehow it didn't get incorporated then.
17288 * doc/autoconf.texi (Limitations of Usual Tools):

17294 * lib/autoconf/general.m4 (_AC_COMPUTE_INT_COMPILE):
17295 Check for `expr' arithmetic overflow, and for compilation failure,
17296 and invoke a new argument $4 if either is discovered.
17297 This makes _AC_COMPUTE_INT_COMPILE more like _AC_COMPUTE_INT_RUN.
17298 (_AC_COMPUTE_INT): Pass IF-FAILS arg to _AC_COMPUTE_INT_COMPILE.

17331 (AC_PROG_CPP requires AC_PROG_CC): here and...
17332 * tests/fortran.at (GNU Fortran 77): there.
17333 * doc/autoconf.texi (autoconf Invocation): Fix the example:
17334 AC_TRY_RUN is about compilation, not shell commands.

17362 2001-09-23 Akim Demaille <akim@epita.fr>
17364 * lib/autoconf/status.m4 (_AC_SRCPATHS): Compute and provide
17365 ac_buildpath, ac_top_buildpath, ac_srcpath, and ac_top_srcpath.

17376 * lib/autotest/general.m4: Do not reset AT_victims.
17377 Don't compute at_srcdir nor at_top_srcdir.
17379 * tests/tools.at: Hence use top_srcdir.
17381 * tests/Makefile.am, tests/autoconf, tests/autoheader,
17382 * tests/autom4te, tests/autoreconf, tests/autoupdate, tests/ifnames:

17436 2001-09-22 Akim Demaille <akim@epita.fr>
17438 * lib/autoconf/autotest.m4: Create `package.m4'.
17439 * tests/Makefile.am (package.m4): Remove.
17441 2001-09-22 Akim Demaille <akim@epita.fr>
17443 Rely on `$LINENO' when possible instead of `__oline__'.
17445 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Provide some form of
17446 `$LINENO' support replacement when not supported.
17447 (_AS_CR_PREPARE, _AS_TR_CPP_PREPARE, _AS_TR_SH_PREPARE): Invoke

17449 (via m4_require). Cosmetic only.

17451 * lib/autoconf/programs.m4: Replace all the occurrences of
17452 `__oline__' with `$LINENO'.
17453 * doc/autoconf.texi (Special Shell Variables): Document LINENO.
17455 2001-09-21 Tim Van Holder <tim.van.holder@pandora.be>
17457 * lib/autoconf/functions.m4 (_AC_FUNC_FORK): Replaceded an 8-bit
17458 character (u: -> ue) in a code comment.
17459 (AC_FUNC_LSTAT_FOLLOWS_SLASHED_SYMLINK): Only run 'ln -s' if we know
17462 2001-09-21 Akim Demaille <akim@epita.fr>
17464 * Makefile.maint (AUTOM4TE): Neutralize autom4te.
17465 Suggested by Jim Meyering.
17467 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
17469 * lib/autoconf/programs.m4: Use extensions listed in
17470 $ac_executable_extensions when looking for programs.
17472 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
17474 * lib/autoconf/general.m4: Fix a small Englisho.

17477 * lib/m4sugar/m4sh.m4: Default CDPATH to $PATH_SEPARATOR, not ':'.
17479 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>

17483 (Special Shell Variables[PATH_SEPARATOR]): Ditto.
17484 (Special Shell Variables[CDPATH]): Mention that $PATH_SEPRATOR should
17485 be used instead of ':'.
17486 * lib/autotest/general.m4: Replace occurrences of ':' in
17487 AUTOTEST_PATH with $PATH_SEPARATOR at test suite startup.
17489 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
17491 * tests/atgeneral.m4: Add basic support for test ranges (e.g. 7-34) as
17492 arguments. Fixed a typo.
17494 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
17496 * man/Makefile.am (.x.1): Use @PATH_SEPARATOR@, not ':' to set up
17497 $PATH. Also set AUTOM4TE_CFG, so we can process autom4te properly.
17499 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
17501 * bin/autoscan.in: Add 'exec-perl-if-not-run-by-perl'.
17502 * bin/autoupdate.in: Ditto.
17503 * bin/autoheader.in: Reworded a few comments.

17508 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
17510 * lib/Autom4te/XFile.pm (open): Simplified the error message (we
17511 already have $file). Set output files to binary mode (helps avoid
17512 CR issues on DOSish systems).
17514 2001-09-19 Akim Demaille <akim@epita.fr>
17516 * lib/autotest/general.m4: Englishoes.
17517 From Tim Van Holder and Alexey Mahotkin.
17519 2001-09-18 Paul Eggert <eggert@twinsun.com>
17521 * doc/autoconf.texi (Common Shell Constructs): New node,
17522 documenting AS_DIRNAME.
17523 (Limitations of Usual Tools): Refer to it when discussing dirname.
17524 Also, update discussion of POSIX standard to reflect latest draft.
17526 * lib/autoconf/c.m4:
17527 (AC_LANG_INT_SAVE(C)): Also support negative values, down to LONG_MIN.
17529 * lib/autoconf/general.m4 (_AC_COMPUTE_INT_COMPILE):
17530 Do not pass a first argument with leading '-'
17531 to expr, by parenthesizing initial integers that might be negative.
17533 * doc/autoconf.texi (Particular Functions): AC_FUNC_GETPGRP
17534 now merely checks whether it is an error to pass an argument
17537 * lib/autoconf/functions.m4 (_AC_FUNC_GETPGRP_TEST): Remove.
17538 (AC_FUNC_GETPGRP): Don't bother with a runtime test. Just check
17539 whether it is a (compile-time) error to pass an argument to
17540 getpgrp. This simpler test supports the revised documentation,
17541 and is all that AC_FUNC_GETPGRP's users really need.
17543 2001-09-18 Akim Demaille <akim@epita.fr>
17545 * doc/autoconf.texi (Limitations of Make) <$<>: New.
17547 2001-09-18 Akim Demaille <akim@epita.fr>
17549 * doc/autoconf.texi (Limitations of Usual Tools) <find>: More about
17551 * lib/autotest/general.m4 (AT_INIT): Adjust.
17553 2001-09-18 Paul Wagland <paul@wagland.net>
17555 * tests/m4sh.at: Ensure that AS_DIRNAME handles '/', '//' and '///'
17557 Add test for AS_BASENAME.
17558 * lib/m4sugar/m4sh.m4: Fix AS_BASENAME so that it passes the previous
17559 added test. It now correctly handles /1/2/3/, returning '3' not ''.
17560 Added AS_BASENAME_SED to make the interface the same as AS_DIRNAME.
17561 * tests/base.at: Fixed the expected responses. The old ones were
17563 * lib/autoconf/general.m4: Fixed AC_PREFIX_PROGRAM, it now behaves as
17564 the documentation claims it should (and how it behaved in 2.13).
17566 2001-09-18 Akim Demaille <akim@epita.fr>
17568 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): No INIT-CMDS in
17569 the AC_CONFIG_COMMANDS invocation.
17570 This also solves the name clash problems.
17571 Don't set the package's ID.
17572 * lib/m4sugar/Makefile.am (version.m4): Revamp.
17573 No longer to be shipped.
17574 (version.in): Remove.
17575 * lib/m4sugar/m4sugar.m4, lib/autoconf/general.m4,
17576 * lib/autoconf/status.m4: Adjust.
17577 Use `m4_PACKAGE_STRING'.
17578 * lib/autotest/general.m4 (AT_INIT): N-th signature change: now
17579 the only optional argument is the name of the test suite.
17580 Expect `package.m4' to define the package signature.
17581 * lib/autom4te.in (Autotest): Add `package.m4?'.
17582 * tests/Makefile.am (package.m4): New.
17583 * tests/suite.at: ifnames is a victim.
17585 2001-09-18 Akim Demaille <akim@epita.fr>
17587 * lib/autom4te.in (Autoconf): Preselect AM_CONDITIONAL,
17588 AC_LIBSOURCE, AC_CONFIG_FILES.
17589 * lib/autotest/general.m4 (AT_INIT): Don't abort when a tested
17590 program version string doesn't match the package's.
17591 * lib/autoconf/general.m4 (AC_CACHE_VAL): Reestablish the space
17594 2001-09-17 Paul Eggert <eggert@twinsun.com>
17596 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):
17597 Allow expression to return any value that can fit into unsigned long
17598 (not int, as before). Check for output errors.
17600 2001-09-17 Bruno Haible <haible@ilog.fr>
17602 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):
17603 Always include <stdio.h> and <stdlib.h>. Evaluate
17604 the expression in an extra function before these includes. Call
17605 fprintf "%d" only after ensuring the argument is of type 'int'.
17606 Reported by Wayne Chapeskie <waynec@spinnaker.com>.
17608 2001-09-17 Paul Eggert <eggert@twinsun.com>
17610 Fix bug reported by Paul Townsend on AIX 4.3.3.0 with CFLAGS=-O4
17611 or CFLAGS=-O5. In that case, the linker has a relaxed view of
17612 fatal errors, and AC_CHECK_LIB causes it to include libraries even
17613 when they don't exist.
17615 * lib/autoconf/headers.m4 (AC_HEADER_DIRENT): Use AC_SEARCH_LIBS,
17616 not AC_CHECK_LIB, so that we don't use -ldir or -lx if we don't
17619 * lib/autoconf/specific.m4 (AC_ISC_POSIX): Replace the old, crufty
17620 version with the version used by fileutils 4.1, except use
17621 AC_SEARCH_LIBS, not AC_CHECK_LIB, so that we don't use -lcposix if

17968 * tests/atspecific.m4, tests/tools.at: Passing --localdir is
17969 indeed related to running the test suite, while passing

18552 * bin/autom4te.in (&handle_output): Don't use `grep' with side
18554 Suggested by Russ Allbery.
18556 2001-08-10 Ralf Corsepius <corsepiu@faw.uni-ulm.de>
18558 * lib/autoconf/general.m4 (_AC_OUTPUT_SUBDIRS): Propagate the
18559 current $prefix to the sub-configures.
18561 2001-08-09 Tim Van Holder <tim.van.holder@pandora.be>
18563 * lib/autoconf/lang.m4: Ignore *.xSYM when looking for an executable
18564 extension (needed on BeOS). Reported by Guido van Rossum.
18566 2001-08-09 Akim Demaille <akim@epita.fr>
18568 * bin/autom4te.in ($icache): Load it only if older than autom4te.
18570 2001-08-07 Akim Demaille <akim@epita.fr>
18572 * lib/autotest/general.m4 (AT_INIT): All the `at-*' are to be
18574 (at-setup-line): Huh? Be a variable `at_setup_line', not a file.
18575 No need to remove the files before and after the each test, before
18576 each test and at the end of the suite is enough.
18577 Display only the children `times', not the shell's.
18578 If the test failed or was skipped, at-times is not available.
18580 2001-08-07 Akim Demaille <akim@epita.fr>
18582 Always produce testsuite.log, including when there are no
18583 failures. This helps getting information on skipped tests, and
18584 duration of the tests. Err, implement the latter btw.
18586 * lib/autotest/general.m4 (AT_INIT): Set up fd 6 for the log.
18587 Dump information on the first run of each test.
18588 (AT_CLEANUP): Create `at-times' containing the duration of the
18591 2001-08-07 Akim Demaille <akim@epita.fr>
18593 The use of `dumpstat' revealed that `len' was used although it
18594 should not. m4_text_wrap was using it, but in the Autoconf world
18595 where it is legal. Hence (i) test M4sh in its own world, not
18596 Autoconf's, and (ii), ahem, fix the bug :)
18598 * lib/autotest/general.m4: Be sure the set good quotes, as tracing
18599 does not like `' instead of [].
18600 (AT_INIT): Forbid `^_?AT_'.
18601 And don't output such tokens.
18602 * tests/Makefile.am (CLEANFILES): Add `script', `script.s4g',
18603 `script.as', and `autom4te.cache'.
18604 Remove `empty' and `macro' which are no longer used.
18605 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): New.
18606 * tests/m4sugar.at: Use it.
18607 * lib/m4sugar/m4sugar.m4: Use `m4_len' not `len'.
18609 2001-08-07 Akim Demaille <akim@epita.fr>
18611 * bin/autoconf.in, bin/autoheader.in: --force, -f is a new option.
18613 2001-08-07 Alexandre Duret-Lutz <duret_g@epita.fr>
18615 * bin/autom4te.in (handle_output): Typo in quadrigraph substitution.
18617 2001-08-04 Akim Demaille <akim@epita.fr>
18619 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA, AC_FUNC_ERROR_AT_LINE)
18620 (AC_FUNC_FSEEKO, AC_FUNC_OBSTACK): Use AC_LANG_IFELSE, not
18622 * lib/autoconf/headers.m4 (AC_HEADER_MAJOR): Likewise.
18623 * lib/autoconf/fortran.m4 (_AC_LANG_PROGRAM_C_F77_HOOKS)
18624 (AC_F77_MAIN): Likewise.
18626 2001-08-04 Akim Demaille <akim@epita.fr>
18628 Don't rely on M4sugar outputting the patterns in files, since we
18629 might process the output _without_ running m4, hence without these
18632 * lib/m4sugar/m4sugar.m4 (m4_init): No need for `m4_tmpdir'.
18633 * bin/autom4te.in (@Request::includes): Remove, unused.
18634 (@Request::source): Rename as...
18635 (@Request::input): this.

18637 (&handle_output): Fetch the patterns from the traces.

18639 (&handle_m4): M4sugar no longer wants `m4_tmpdir'.
18640 (m4_pattern_forbid, m4_pattern_allow): Adjust for tracing only.
18642 2001-08-04 Akim Demaille <akim@epita.fr>
18644 `autoconf && autoheader' is sped up. Now, speed up `autoheader &&
18645 autoconf', i.e., in addition to caching traces, cache the output.
18647 * bin/autom4te.in (Request::cache): Rename as...
18648 (Request::id): this.
18649 ($cache, $icache, $tcache, $ocache): New.
18650 (&handle_m4): Save M4 output in the cache instead of $tmp.

18658 * bin/autom4te.in ($force): New.
18659 (&parse_args, &print_usage): -f, --force is a new option.
18660 (&handle_output): CPP directives might have spaces after `#'.
18661 (&parse_args): The first file only can be frozen.
18663 2001-08-04 Akim Demaille <akim@epita.fr>
18665 Don't let autom4te compute the `include' traces several times:
18666 first check that the trace cache file is up to date, and then
18667 compare its timestamp with that of the output.
18669 * bin/autom4te.in, bin/autoupdate.in, bin/autoscan.in: Normalize
18670 the preamble. Don't require 5.005 as Autom4te::General does it,
18671 and better yet (use `use', not `require'!).
18672 * lib/Autom4te/Struct.pm: Rename the last occurrences of
18673 Class::Struct as Autom4te::Struct.
18674 * lib/Autom4te/General.pm (File::stat): Use it.
18675 (&mtime): New, export it.
18676 * bin/autom4te.in: Use it.
18677 Declare `$req' is invalid if it is outdated.
18678 Don't declare it valid before saving it if something went wrong.
18680 2001-08-04 Akim Demaille <akim@epita.fr>
18682 Autom4te shall not encode Autoconf data, and preselecting traces
18683 must be proposed to the users.
18685 * bin/autom4te.in (@required_trace): Remove.
18687 (&parse_args, &print_usage): -p, --preselect is a new option.
18688 (&up_to_date_p): Adjust.

18715 (%m4_builtin_alternate_name): New.
18716 (&parse_args): Complete the trace requests with alternate names.

18728 (m4_divert_pop): Dump the whole diversion stack when a diversion
18730 * bin/autom4te.in (&handle_output): Remember of the first
18731 occurrence of a possibly undefined macro, not the last.

18733 the appear in the output.
18734 * lib/autoconf/Makefile.am (autoconf.m4f): List its dependencies.
18735 * tests/tools.at (autoconf: forbidden tokens, basic)
18736 (autoconf: forbidden tokens, exceptions): No longer sort
18737 autoconf's stderr, as it is now deterministic.
18738 Check that `dnl' is caught.

18761 * bin/autoupdate.in, bin/autoscan.in: Improve error messages accuracy.
18762 * bin/autoupdate.in (File::Compare, File::Copy): Use them instead of
