6570 (AT_INIT) <PARSE_ARGS_END>: ...here, since -k always takes
6572 <DEFAULTS>: Delay computation of variables based on $at_dir...
6573 <PREPARE_TESTS>: ...to here, since -C can change $at_dir.
6574 <TESTS>: Re-invoke via absolute name, since -C may be in effect.
6575 <PARSE_ARGS>: Parse new option.

6590 2008-01-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6592 * doc/autoconf.texi (Particular Programs): Do not mention the
6593 Autoconf version in which the AC_PROG_INSTALL change was done.
6594 Suggested by Paul Eggert.
6596 2008-01-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6598 Fix --help=recursive with multiple AC_CONFIG_SUBDIRS.
6599 * lib/autoconf/general.m4 (_AC_INIT_HELP): If, for recursive help
6600 mode, we change to the source directory, also set $ac_pwd so we
6601 do not go back to the build tree for the next config subdir.
6602 * tests/torture.at (Deep Package): Extend test to contain two
6603 config subdirs on the top level.
6605 Fix parallel `maintainer-check'.
6606 * Makefile.am (maintainer-check-tests): Depend on `all'.

6659 Fix some whitespace tests on cygwin.
6660 * tests/tools.at (autom4te and whitespace in file names): Restore
6661 font-lock. Create $TMPDIR before it might be used.

6664 * tests/local.at (AT_CHECK_M4): Cater to new m4 error message.
6666 Optimize AC_REQUIRE.
6667 * lib/m4sugar/m4sugar.m4 (m4_expansion_stack_push, _m4_defun_pro)
6668 (_m4_defun_pro_outer, _m4_defun_epi, _m4_defun_epi_outer)
6669 (m4_require): Avoid extra macro calls.
6671 2007-12-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6673 * tests/torture.at (srcdir): Fix quoting.
6675 Do not pass top_srcdir to configure scripts in testsuite.
6676 * tests/autotest.at (srcdir propagation): Copy install-sh to

6679 * tests/base.at (Input/Output): Likewise.
6680 * tests/local.at (AT_CONFIGURE_AC): Copy install-sh,
6681 config.guess, and config.sub to test source tree.
6682 Drop AC_CONFIG_AUX_DIR setting.
6683 (AT_CHECK_CONFIGURE): Drop setting of `top_srcdir'.
6684 * tests/torture.at (Substitute a 2000-byte string): Drop
6685 AC_CONFIG_AUX_DIR setting, copy install-sh to test source tree.
6686 (Substitute a newline, datarootdir workaround): Likewise.
6687 (Define a newline): Adjust for linenumber changes in configure.ac.
6688 * tests/foreign.at (Libtool): Adjust comment to reflect changes.

6695 * tests/tools.at (Syntax of the shell scripts): Likewise.
6697 * tests/m4sh.at (LINENO): Quote $0.
6699 Fix testsuite program wrapper for whitespace in `pwd`.
6700 The problem here is that the usual mantra is that command
6701 variables can contain arguments, thus we cannot just escape
6702 $AUTOCONF, $AUTOM4TE etc. The compromise is to put the
6703 $top_builddir/tests directory early in $PATH, so that the
6704 wrappers are found by their plain name.
6705 * tests/wrapper.as: Put $testdir early in $PATH.
6706 (AUTOCONF, AUTOHEADER, AUTOM4TE): Set to plain command names.
6708 Proper config.status --file/--header and $srcdir escaping.

6719 Quote $at_group_dir.
6720 * tests/autotest.at (whitespace in absolute testdir): New test.
6722 * lib/autom4te.in: Quote @datadir@.
6724 Proper file name escaping in Autoconf programs and Perl modules.
6725 This includes escaping of characters special to the shell
6726 as well as special to Perl, e.g., leading `<' or `>'.
6727 For example, when $file starts with `>', `open ">$file"'
6728 wrongly tries to append to a different file.
6729 * bin/autoconf.as: Fix quoting for autom4te options.
6730 * lib/Autom4te/General.pm (shell_quote): New function, taken
6731 from coreutils, written by Jim Meyering.
6733 * bin/autom4te.in (files_to_options, handle_m4): Use shell_quote
6735 * bin/autoreconf.in (parse_args): Likewise.

6739 * bin/ifnames.in: Likewise, XFile usage fixes.
6740 * tests/tools.at (autom4te and whitespace in file names): Extend
6741 test. Test twice, with special characters allowed on w32, and the
6742 rest. Test leading and trailing whitespace, for `open_quote'.
6743 (autotools and whitespace in file names): New, analogous test.
6744 Reported by Paul Eggert and Benoit Sigoure, additional suggestions
6745 by Russ Allbery and Eric Blake.
6748 * lib/Autom4te/Channels.pm, lib/Autom4te/Configure_ac.pm,
6749 lib/Autom4te/Struct.pm, lib/Autom4te/XFile.pm: Likewise.
6750 * lib/Autom4te/FileUtils.pm (open_quote): New function.
6751 (update_file, contents): Use it.
6753 * Makefile.am (autom4te-update): Rewrite for git.
6755 2007-12-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6757 * doc/autoconf.texi (autom4te Invocation, Autom4te Cache): Fix typos.
6759 Fix copyright years.
6760 * Makefile.am, doc/install.texi, lib/autoconf/fortran.m4,
6761 lib/autoconf/lang.m4, lib/freeze.mk: Likewise.
6763 2007-12-04 Eric Blake <ebb9@byu.net>
6765 Manually resync with gnulib, since 'make cvs-update' no longer works.

6771 * doc/Makefile.am (TEXINFO_TEX): Add.
6773 2007-11-27 Paul Eggert <eggert@cs.ucla.edu>
6775 Fix AC_C_BIGENDIAN bug caused by new awk method of substitution.
6776 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Don't comment out the
6777 #undef as this runs afoul of our new way of creating config.h.
6778 Problem reported by Jim Meyering in
6779 <http://lists.gnu.org/archive/html/autoconf-patches/2007-11/msg00164.html>.
6781 2007-11-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6783 Fix autom4te for unusual characters in input file names.
6784 * bin/autom4te.in (files_to_options): Quote active characters
6786 * tests/tools.at (autom4te and white space in file names):
6789 * doc/autoconf.texi (Limitations of Usual Tools) <awk>:
6790 Document that Tru64 awk always splits $0.
6792 2007-11-24 Stepan Kasal <kasal@ucw.cz>
6794 * lib/autotest/general.m4 (AT_INIT): Do not extract the
6795 `#AT_STOP_...' line at the end of each test.
6797 2007-11-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6799 * lib/autotest/general.m4 (AT_INIT): For awk line number
6800 extraction script, ensure `$at_group' has a defined value
6801 even for the empty set, and properly quote its usage inside
6804 2007-11-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6806 * doc/autoconf.texi (Shell Functions): New chapter. Document
6807 IRIX sh $0 issue in functions, move content from ...
6808 (Portable Shell): ... here.
6809 (Shell Script Compiler): Note that shell functions are not
6810 totally unportable any more.
6812 2007-11-22 Stepan Kasal <kasal@ucw.cz>
6813 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6815 * lib/autotest/general.m4 (AT_INIT): Exit awk script after
6816 extracting the line numbers of the last needed test.
6818 2007-11-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6820 * lib/autotest/general.m4 (AT_INIT) <at_func_create_debugging_script>:
6823 2007-11-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6825 Fix IRIX testsuite debugging failures: $0 in functions.
6826 * lib/autotest/general.m4 (AT_INIT) <at_func_create_debugging_script>:
6827 Do not use $0 inside a function, as IRIX sh will set that to the
6828 function name rather than the script invocation name.
6830 2007-11-19 Paolo Bonzini <bonzini@gnu.org>
6831 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6833 * lib/autotest/general.m4 (at_func_test): Use cached line numbers
6834 to extract test scripts.
6835 (AT_INIT): Extract and cache test script line numbers.
6837 2007-11-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6839 * lib/autotest/general.m4: Revert 2007-11-15 patch and
6840 subsequent fixups; the awk -> here-document conversion trashes
6841 performance too much with AIX sh.
6843 2007-11-18 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6845 * tests/local.at: Do not test m4, perl with AT_TESTED.
6847 Diagnose and guard against write errors dealing with config.status.
6848 The general idea is this: all write failures from `configure'
6849 writing `config.status' are indicated by $ac_write_error, which
6850 is only checked at the end. This is safe because config.status
6851 code is not executed before the file is complete. Other write
6852 failures, be they inside config.status, or in sub shell/awk
6853 scripts spawned from configure or config.status, typically need
6854 earlier checking, as their results are used right afterwards.
6855 * lib/autoconf/status.m4 (AC_OUTPUT): Initialize `ac_write_fail'
6856 before writing config.status, check afterwards.
6857 (_AC_OUTPUT_FILES_PREPARE, _AC_OUTPUT_FILE)
6858 (_AC_OUTPUT_HEADERS_PREPARE,_AC_OUTPUT_CONFIG_STATUS):
6859 Set `ac_write_error' for write failures to config.status. Barf
6860 upon write failures to temporary files.
6861 Adjust note about closing and reopening the here-document.
6862 (_AC_OUTPUT_HEADER, _AC_OUTPUT_LINK, _AC_OUTPUT_COMMAND)
6863 (_AC_OUTPUT_MAIN_LOOP): Likewise, adjust note about closing and
6864 reopening the here-document.
6865 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
6866 Ensure `ac_write_error' does not escape into config.status.
6867 Also, add a couple of code paths not yet exercised in the test
6868 suite: a config file with input from stdin, and a config header
6870 Suggestion for catching write errors by Bruno Haible.
6872 2007-11-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6874 Avoid error with Tru64 awk and testsuite lines with many words.
6875 * lib/autotest/general.m4 (AT_INIT): In the awk script that
6876 reads the testsuite, set the field separator to an unusual value,
6877 in order to not run over the limit of 199 fields. Tru64 4.0D awk
6878 even splits the input if $i, i>0, was never accessed in the script.
6880 Revert 2007-10-17 change.
6881 * TODO: Multiline args in config files and headers mean something
6882 different and are not fixed, see

6890 AC_*_TOOL does not canonicalize the prefix
6891 * doc/autoconf.texi (Generic Programs): Do not say that

6957 Do not check for preprocessor flaws.
6959 2007-11-13 Jim Meyering <meyering@redhat.com>

6966 Use $@, not literal "version.m4".
6968 2007-11-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6970 * doc/autoconf.texi (Making testsuite Scripts): Document
6971 ":;{" shorthand as in previous patch.
6973 2007-11-12 Paul Eggert <eggert@cs.ucla.edu>
6975 * doc/autoconf.texi (Limitations of Builtins): Document problem
6976 with { ... } a bit more clearly. Suggest ":;{" as a shorthand
6978 * lib/m4sugar/Makefile.am (version.m4): Detect 'echo' failure.
6979 Use ":;{" shorthand.
6980 * tests/Makefile.am ($(srcdir)/package.m4): Likewise.
6982 2007-11-12 Jim Meyering <meyering@redhat.com>
6984 Add more non-srcdir build support.
6985 * GNUmakefile (dummy): Split a long line.
6986 Add -v option to autoreconf invocation.
6988 Remove the autoreconf-provided INSTALL, so that we regenerate it.
6989 * GNUmakefile (dummy): Remove INSTALL.
6991 Remove racy commands to build scripts in bin/ and tests/.
6992 * man/Makefile.am (.x.1): Now that scripts in bin/ and tests/
6993 are guaranteed to be built, remove the rules that tried to build
6994 them. Before, with a parallel build, these rules could lead to
6995 two processes writing tests/wrapper.in concurrently.
6997 Build in man/ only *after* building in bin/ and tests/.
6998 * Makefile.am (SUBDIRS): The man-page-creation process runs $(MAKE)
6999 in both bin/ and tests/.
7001 Accommodate non-srcdir build-from-checkout.
7002 * build-aux/git-version-gen: Require an additional parameter: $srcdir.
7003 Use git's --git-dir=$srcdir/.git option.
7004 Add quotes, in case tarball_version_file contains shell meta-characters.
7005 * GNUmakefile (_curr-ver): Pass $(srcdir) to git-version-gen.
7006 * configure.ac: Pass "." to git-version-gen.
7008 Avoid spurious test failures due to version skew.
7009 * GNUmakefile (dummy): Run $(MAKE) clean after autoreconf -i.
7011 2007-11-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7013 Avoid warnings about conftest.dSYM directories on Mac OS X Leopard.
7014 * lib/autoconf/general.m4 (_AC_LINK_IFELSE, _AC_RUN_IFELSE):
7015 Remove conftest.dSYM directory.
7016 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT)
7017 (_AC_LANG_PROGRAM_C_, _AC_FC_MAIN, __AC_FC_NAME_MANGLING):
7018 Remove `conftest.*' recursively.
7019 * lib/autoconf/lang.m4 (AC_LINK_IFELSE): Likewise.
7020 * lib/autoconf/specific.m4 (_AC_SYS_LARGEFILE_MACRO_VALUE):
7022 (_AC_COMPILER_OBJEXT_REJECT): Reject *.dSYM.
7024 Report and analysis by Jeff Squyres and Peter O'Gorman.
7026 2007-11-12 Benoit Sigoure <tsuna@lrde.epita.fr>
7028 Fix typos in variable names.
7029 * tests/semantics.at (test for AC_CHECK_LIB): s/at_m/ac_m/.
7031 2007-11-11 Benoit Sigoure <tsuna@lrde.epita.fr>
7033 Document that $((expression)) is not portable.
7034 * doc/autoconf.texi (Shell Substitutions): Here.
7036 2007-11-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7038 Ignore configure --help* errors due to LINENO-impaired shells.
7039 * tests/torture.at (Configuring subdirectories, Deep Package):
7040 In the --help* tests in read-only trees, make `.' temporarily
7041 writable again for the `stderr' file, and ignore errors due to
7042 the attempt to write configure.lineno.
7043 Report by Patrick Welche.
7045 2007-11-10 Jim Meyering <meyering@redhat.com>
7047 Generate package.m4 in build-dir, not srcdir.
7048 * tests/Makefile.am (package.m4): Adjust target.
7049 Don't redirect directly to $@.
7050 (CLEANFILES): Add package.m4.
7051 ($(TESTSUITE)): Depend on just-built package.m4, not the one
7053 When running $(AUTOTEST), search "." before searching $(srcdir).
7055 Avoid a race condition that would make parallel "distclean" fail.
7056 * tests/Makefile.am (distclean-generic): Replace the default,
7057 automake-provided rule with an identical one, but with an additional
7058 dependency on distclean-local. Simply adding the dependency would
7059 cause automake not to emit the rule at all.
7060 * BUGS: Building with -jN works, now.
7062 Distribute git-version-gen.
7063 * Makefile.am (EXTRA_DIST): Add build-aux/git-version-gen,
7064 since GNUmakefile is distributed, and requires it for dist* rules.
7066 Remove two more generated files from version control.
7067 * INSTALL: Remove generated file.
7068 * lib/autoscan/autoscan.list: Remove generated file.
7070 2007-11-09 Paul Eggert <eggert@cs.ucla.edu>
7072 * GNUmakefile (PATH): Remove stray apostrophes; they become
7073 part of PATH, which isn't wanted here.
7075 2007-11-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7077 New config files output variable `top_build_prefix'.
7078 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Substitute
7080 * doc/autoconf.texi (Preset Output Variables): Document it.
7082 Report by Bob Friesenhahn.
7084 Avoid expr for arithmetic evaluation if the shell accepts $((...)).
7085 * lib/autotest/general.m4 (AT_INIT) <at_func_arith>: New
7086 function, to parametrize arithmetic with expr vs. the shell.
7087 Use it where possible.
7088 Suggestion by Benoit Sigoure.
7090 2007-11-03 Benoit Sigoure <tsuna@lrde.epita.fr>
7092 Adjust the documentation of autotest WRT atlocal.
7093 * doc/autoconf.texi (Making testsuite Scripts): It is not necessary,
7094 when using Automake, to write a rule to produce atlocal, since it's
7095 an AC_CONFIG_FILES. Mention that atlocal.in needs to be
7096 distributed, not atconfig.in.
7098 2007-11-04 Eric Blake <ebb9@byu.net>
7100 Update list information.
7101 * README: Mention new autoconf-commit list.

7106 * lib/autoconf/functions.m4 (_AC_FUNC_MALLOC_IF): Fix comment typo.
7108 * lib/m4sugar/Makefile.am (version.m4): Another bash bug workaround.
7110 * build-aux/.gitignore: Ignore mkinstalldirs.
7112 * doc/autoconf.texi (autoreconf Invocation): Fix an underfull line.
7114 2007-11-03 Jim Meyering <meyering@redhat.com>
7116 s/-/./ in snapshot version string: 2.61a-256-8b556 -> 2.61a.256-8b556
7117 * build-aux/git-version-gen: This syncs from coreutils.
7119 Adjust the build procedure so "make check" works reliably.
7120 * README-hacking: Include an extra step between "make" and
7121 "make check" to ensure that the latter passes.
7123 Use just-built tools, when possible.
7124 * GNUmakefile (PATH): Set and export here, ...
7125 (dummy): ... rather than here.
7127 2007-11-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7128 and Andreas Schwab <schwab@suse.de>
7130 * tests/Makefile.am ($(srcdir)/package.m4): Work around bash
7133 2007-11-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7135 * configure.ac (AC_PREREQ): Require version 2.60, for
7136 AC_PROG_SED, AC_PROG_GREP.
7138 2007-11-02 Benoit Sigoure <tsuna@lrde.epita.fr>
7139 and Jim Meyering <meyering@redhat.com>

7144 * doc/autoconf.texi (Limitations of Builtins): Mention that GNU
7145 Bash doesn't properly set $? when `{ ... } >/bad' fails, and give
7148 2007-11-03 Eric Blake <ebb9@byu.net>
7150 Support m4 1.4.5 in testsuite.
7151 * tests/torture.at (Define a newline): Exclude line numbers in
7153 Reported by Ralf Wildenhues.
7155 2007-11-03 Jim Meyering <meyering@redhat.com>
7157 Remove automake-provided files from version control.
7158 * build-aux/elisp-comp: Remove file.
7159 * build-aux/install-sh: Remove file.
7160 * build-aux/missing: Remove file.
7161 * build-aux/mdate-sh: Remove file.
7162 * build-aux/.gitignore: New file.
7163 Suggestion from Ralf Wildenhues.
7165 2007-11-03 Eric Blake <ebb9@byu.net>
7167 Adjust version comparison to account for git snapshot numbers.
7168 * lib/m4sugar/m4sugar.m4 (_m4_version_unletter): Also treat - as a
7169 component separator.

7171 <m4_version_compare>: Document this change.
7172 * tests/m4sugar.at (m4@&t@_version_compare): Test it.
7174 2007-10-30 Bruno Haible <bruno@clisp.org>
7176 * lib/autoconf/types.m4 (_AC_TYPE_LONG_LONG_SNIPPET): New macro,
7177 extracted from AC_TYPE_LONG_LONG_INT and AC_TYPE_UNSIGNED_LONG_LONG_INT.
7178 (AC_TYPE_LONG_LONG_INT, AC_TYPE_UNSIGNED_LONG_LONG_INT): Use it.
7179 Fixes problem with Sun C 5.[0-8] in 32-bit mode, reported in
7180 <http://lists.gnu.org/archive/html/autoconf-patches/2007-10/msg00210.html>
7181 Suggested by Paul Eggert.
7183 2007-10-28 Jim Meyering <meyering@redhat.com>
7185 * README-hacking: Autoconf, Automake, and Perl are required to build.
7186 List Gzip and Tar separately. Suggested by Ralf Wildenhues.
7188 2007-10-28 Jim Meyering <meyering@redhat.com>
7190 README-hacking: Recommend running autoreconf -vi.
7191 * GNUmakefile (dummy): Use autoreconf -i, with appropriate PATH,
7192 so that we use just-built tools when they're available.
7193 Suggestions from Ralf Wildenhues.
7195 2007-10-28 Jim Meyering <meyering@redhat.com>
7197 Make inter-release --version output more useful.
7199 Now, each unofficial build has a version "number" like 2.61a-19-58dd,
7200 which indicates that it is built using the 19th change set
7201 (in _some_ repository) following the "v2.61a" tag, and that 58dd
7202 is a prefix of the commit SHA1.
7203 * build-aux/git-version-gen: New file.
7204 * configure.ac: Run it to set the version.
7205 (AM_INIT_AUTOMAKE): Don't check NEWS here.
7206 * Makefile.am (dist-hook): Arrange so that .version appears only
7207 in distribution tarballs, never in a checked-out repository.
7208 * .gitignore: Add .version here, too. Just in case.
7209 * tests/Makefile.am ($(srcdir)/package.m4): Depend on Makefile,
7210 not configure.ac, now that the version number changes automatically.
7212 Ensure that $(VERSION) is up to date for dist-related targets.
7213 * GNUmakefile: Arrange to rerun autoconf, if the version reported by
7214 git-version-gen doesn't match $(VERSION), but only for dist targets.
7216 2007-10-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7218 Fix `Deep Package' failure with a configure script early in PATH

7248 problem reported by Bruno Haible in
7249 <http://lists.gnu.org/archive/html/bug-autoconf/2007-10/msg00027.html>.
7251 2007-10-22 Eric Blake <ebb9@byu.net>
7253 * doc/autoconf.texi (Particular Types): Mention bug in HP-UX 11.00
7256 2007-10-22 Paul Eggert <eggert@cs.ucla.edu>
7258 Don't check for bug in HP-UX 11.00 cpp.
7259 * lib/autoconf/types.m4 (AC_TYPE_UNSIGNED_LONG_LONG_INT):
7260 Use -1ull rather than -1u, since that causes problems with gnulib; see
7261 <http://lists.gnu.org/archive/html/bug-gnulib/2007-10/msg00329.html>.

7279 escaping of backslash in here-documents.
7281 Fix `Deep Package' test failure on FreeBSD.
7282 * tests/torture.at (Deep Package): Do not add `.' to $PATH
7283 unnecessarily. Do not try running `/bin/sh configure' with a
7284 configure script to be found in $PATH, if the shell does not do
7285 this resolution. Fixes test failure on FreeBSD.
7287 Fix config header generation with AIX awk.
7288 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS_PREPARE): In awk
7289 script, use helper array D_is_set, as `" 0"' does not evaluate
7290 to true for AIX awk.
7292 2007-10-21 Eric Blake <ebb9@byu.net>

7327 * lib/autotest/general.m4 (BANNERS): New named diversion.
7328 (TESTS_END): Diversion no longer used.
7329 (AT_INIT) <at_func_banner, BANNERS>: Factor all banners into a
7330 shell function, which prints only as needed, using an associative
7331 array of banner text from a special diversion.
7332 <PARSE_ARGS_END>: No longer need awk to find banners.
7333 <TESTS>: Banners are no longer processed by main driver loop, so
7334 we no longer need case statement.
7335 (AT_BANNER): Rewrite to populate new diversion.
7336 (AT_SETUP): Each test invokes its own banner. No output is needed
7337 to the TESTS diversion.

7364 duplication bug by using new macro.
7365 (AT_INIT) <at_tested>: Restore newline separators. Invoke tested
7366 programs with stdin redirected, so programs that don't
7367 understand --version won't try to behave interactively.
7368 * tests/autotest.at (Tested programs): Catch this bug.
7369 * tests/m4sugar.at (m4@&t@_append): Test new macro.

7429 is not writable, use 'cp -p' in this case, in the hope that it
7430 will not actually be needed. Still try removing files, in case
7431 of other write errors.
7432 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): For ac_confdir,
7433 use $as_myself, not $0.
7434 (_AC_INIT_HELP): For --help=recursive, if the subdir does not
7435 exist, try again in the the source tree. This change assumes
7436 that the subpackage configure script is capable of running
7437 --help=recursive in the source tree.

7439 Adjust tests to expose both issues, also try invocation as

8451 2007-05-01 Kevin Ryde <user42@zip.com.au>
8453 * doc/autoconf.texi (Particular Programs): Typo
8454 @acindex{AC_PROG_MKDIR_P} shouldn't have "AC" in that call.
8456 2007-04-30 Paul Eggert <eggert@cs.ucla.edu>
8458 * lib/m4sugar/m4sh.m4 (_AS_SHELL_FN_SPY): Don't imply that
8459 'configure' will fail if the shell lacks proper support for shell
8460 functions. Suggested by RMS.
8462 2007-04-29 Paul Eggert <eggert@cs.ucla.edu>
8464 * doc/autoconf.texi (Limitations of Builtins): Correct the warning
8465 about Solaris /bin/printf '%010000x' 123. Problem reported by
8468 2007-04-28 Paul Eggert <eggert@cs.ucla.edu>
8470 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't look
8471 for a.* when searching for executables, as this prevents users
8472 from having files like a.c. Problem reported by Ralf Wildenhues in:
8473 http://lists.gnu.org/archive/html/autoconf-patches/2007-04/msg00029.html
8474 This fixes a problem introduced on 2000-12-19.
8476 2007-04-26 Paul Eggert <eggert@cs.ucla.edu>
8478 * doc/autoconf.texi (Limitations of Builtins): Warn about Solaris
8479 /bin/printf '%010000x' 123. Problem reported by Arto C. Nirkko
8482 2007-04-12 Paul Eggert <eggert@cs.ucla.edu>
8484 * NEWS: Document recent changes to AC_CHECK_ALIGNOF, AC_CHECK_SIZEOF,
8485 AC_CHECK_TYPE, AC_CHECK_TYPES.
8486 * doc/autoconf.texi (Generic types): C types must be type-names
8487 (the C terminology), not type-ids (the C++ term). C++ types
8488 must not be anonymous.
8489 * lib/autoconf/types.m4 (_AC_CHECK_TYPE_NEW): Remove special case
8490 for C++; this drops support for anonymous struct and union types,
8491 which were problematic anyway.
8492 * tests/semantics.at (AC_CHECK_HEADERS_NEW): Adjust test to work even
8495 2007-04-12 Jim Meyering <jim@meyering.net>
8497 * doc/autoconf.texi (Libraries): Typo fix: insert missing "in".
8499 2007-04-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8501 * lib/autoconf/status.m4 (_AC_OUTPUT_LINK): Fix AC_CONFIG_LINKS
8502 to prefer a link source from the build tree, if it exists.
8503 Report by Pallav Gupta <pallavgupta@gmail.com>.
8505 2007-04-11 Paul Eggert <eggert@cs.ucla.edu>
8507 * doc/autoconf.texi (Generic Types): Document the restrictions
8508 on types imposed by AC_CHECK_TYPE, AC_CHECK_TYPES.
8509 (Generic Compiler Characteristics): AC_CHECK_SIZEOF now works
8510 with objects too. Document the restrictions on its use.
8511 Document the restrictions on AC_CHECK_ALIGNOF's type argument.
8512 * lib/autoconf/types.m4 (_AC_CHECK_TYPE_NEW):
8513 For C, just try sizeof (TYPE) and sizeof ((TYPE)); if the former
8514 works but the latter doesn't, then it's a valid type.
8515 This lets people use function types and so forth.
8516 For C++ there doesn't seem to be a simple solution, so leave it alone.
8517 (AC_CHECK_SIZEOF): Allow argument to be a variable.
8518 (AC_CHECK_SIZEOF, AC_CHECK_ALIGNOF): Don't bother to invoke
8519 AC_CHECK_TYPE; that wasn't documented or necessary.
8521 2007-04-11 Stepan Kasal <kasal@ucw.cz>
8523 * lib/autoconf/general.m4 (_AC_LINK_IFELSE): Skip AS_TEST_X
8524 when cross-compiling.
8526 2007-04-11 Stepan Kasal <kasal@ucw.cz>
8528 * doc/autoconf.texi (External Software): Fix a typo in the
8531 2007-04-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

8534 Fix ambiguous wording. Report by Reuben Thomas <rrt@sc3d.org>.
8536 2007-04-06 Paul Eggert <eggert@cs.ucla.edu>
8538 * doc/autoconf.texi (Particular Types): AC_C_LONG_DOUBLE is now
8539 obsolescent. Suggested by Bruno Haible.
8540 * NEWS: Document this.
8542 2007-03-29 Paul Eggert <eggert@cs.ucla.edu>
8544 * doc/autoconf.texi (Here-Documents, Limitations of Builtins):
8545 (Limitations of Usual Tools): Don't say "older" if Solaris 10 by
8546 default still has the problem. Problem reported by Bruce Korb.
8548 2007-03-28 Stepan Kasal <kasal@ucw.cz>
8549 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8551 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Fix a
8552 comment in the generated config.status.

8561 command and case statements to make it a bit clearer and describe
8564 2007-03-23 Paul Eggert <eggert@cs.ucla.edu>
8566 * doc/autoconf.texi (C Compiler): Mention that AC_PROG_CC_C99 also
8567 checks for unsigned long long int.
8569 2007-03-19 Paul Eggert <eggert@cs.ucla.edu>
8571 * doc/autoconf.texi (Limitations of Usual Tools): Warn about other
8572 nonstandard grep R.E. escape sequences.
8574 2007-03-17 Jim Meyering <jim@meyering.net>
8576 * doc/autoconf.texi: Adjust grammar around use of "heuristics".
8577 (Limitations of Usual Tools): Also list \< and \>, and mention that
8578 HP-UX's grep, like the one from Solaris, does not support that syntax.
8580 2007-03-09 Stepan Kasal <kasal@ucw.cz>
8582 * doc/autoconf.texi (Specifying Names): `--host' does not
8583 change the build type.
8585 2007-03-05 Paul Eggert <eggert@cs.ucla.edu>
8587 * doc/autoconf.texi (C Compiler): Warn that AC_C_BIGENDIAN
8588 suggests AC_CONFIG_HEADERS.
8589 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Warn if not using
8590 AC_CONFIG_HEADERS. Problem reported by

8595 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Fix typo "__LITLE_ENDIAN__".
8596 Problem reported by Paolo Bonzini in:
8597 http://lists.gnu.org/archive/html/autoconf-patches/2007-02/msg00024.html
8598 * tests/semantics.at (AC_C_BIGENDIAN): Don't reject hosts that have
8599 universal binaries. Problem reported by Elias Pipping.
8601 2007-02-27 Paul Eggert <eggert@cs.ucla.edu>
8603 * NEWS: AC_C_BIGENDIAN now supports universal binaries a la Mac OS X.
8604 * doc/autoconf.texi (C Compiler): Document this. There is a new
8605 extra argument ACTION-IF-UNIVERSAL.
8606 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Implement this.
8607 Add support for Solaris-style _LITTLE_ENDIAN and _BIG_ENDIAN.
8608 Reindent for sanity's sake.
8610 2007-02-24 Eric Blake <ebb9@byu.net>
8612 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Update
8614 * lib/autoconf/general.m4 (_AC_INIT_COPYRIGHT): Likewise.
8615 * lib/autotest/general.m4 (AT_INIT): Likewise.
8616 (_AT_DECIDE_TRACEABLE): Fix syntax highlighting.
8618 2007-02-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8620 * lib/autotest/general.m4 (AT_INIT): With --clean, return exit
8621 status of rm so we know when it failed.
8622 If cleaning of test dir failed before running the test, warn.
8623 Output the line separator in verbose mode before the warning
8624 to make clear the warning belongs to the following test.
8626 2007-02-08 Paul Eggert <eggert@cs.ucla.edu>
8628 * doc/autoconf.texi (Parentheses): Mention problem with (( in

8635 errors introduced in last change.
8637 2007-02-07 Paul Eggert <eggert@cs.ucla.edu>
8639 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Prefer \r to
8640 an actual carriage return. Use "ac_cr" to contain the actual

8649 2007-02-06 Ralf Menzel <menzel@ls6.cs.uni-dortmund.de> (tiny change)
8651 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Redirect
8652 input from /dev/null in awk test, so even Solaris /usr/bin/awk
8653 will not wait for input with a script containing only a BEGIN
8656 2007-02-03 Paul Eggert <eggert@cs.ucla.edu>
8658 * doc/autoconf.texi (Introduction, Why GNU M4): Clarify M4 version

8676 * THANKS (people): Update.
8678 2007-01-28 Paul Eggert <eggert@cs.ucla.edu>
8680 * doc/autoconf.texi (Shellology): pdksh 5.2.14 is still the
8682 (Shell Substitutions): Note problems with @{var:=value} etc.
8683 Add a new section for problems with @{#var} etc. Problem noted

8687 2007-01-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8689 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Also
8690 AC_SUBST([MKDIR_P]), so that Automake < 1.10 will pick up its
8691 trace, if a package uses AC_PROG_MKDIR_P explicitly. The actual
8692 substitution will still be done by the special code.
8693 Report by Jim Meyering.
8695 * doc/autoconf.texi (File System Conventions): Mention that
8696 $PATH_SEPARATOR is for the build system only.
8697 Report by Keith Marshall.

8707 Test all 8 bit non-NUL characters.
8708 Report against Automake by Patrick Welche.
8710 2007-01-15 Stepan Kasal <kasal@ucw.cz>
8712 * doc/autoconf.texi: Direntry for "autoconf Invocation" renamed.
8714 2007-01-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8716 * lib/autoconf/programs.m4 (AC_PROG_SED): When closing a pipe
8717 early on the reader side, drop stderr of the input to avoid
8718 `broken pipe' error output; this may happen even with shell
8719 builtin `echo' of some bash versions. Reports by Ian Macdonald
8720 <iamacdo@telkomsa.net> and Sam Sexton <Sam.Sexton@reuters.com>.
8722 2007-01-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8724 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Use newlines to

8735 http://lists.gnu.org/archive/html/autoconf-patches/2007-01/msg00077.html
8736 * doc/autoconf.texi (Signed Overflow Examples): Give more
8737 discussion about the allow_superuser_privileges example,
8738 and change it a bit to make things clearer.
8739 (Optimization and Wraparound): Clarify whether the compiler
8740 will generate an infinite loop for the example derived from
8741 Autoconf's mktime test.
8742 (Signed Overflow Advice): Say that -ftrapv is meant for debugging.
8743 Also, clarify unsigned multiplication overflow.
8745 2007-01-04 Eric Blake <ebb9@byu.net>
8747 * bin/Makefile.am (RELEASE_YEAR): New macro.
8748 (edit): Use it to supply correct copyright year to scripts.
8749 * bin/autoconf.as (version): Use it.
8750 * bin/autoheader.in ($version): Likewise.
8751 * bin/autom4te.in ($version): Likewise.
8752 * bin/autoreconf.in ($version): Likewise.
8753 * bin/autoscan.in ($version): Likewise.
8754 * bin/autoupdate.in ($version): Likewise.
8755 * bin/ifnames.in ($version): Likewise.
8757 2007-01-02 Paul Eggert <eggert@cs.ucla.edu>
8759 * doc/autoconf.texi (Integer Overflow): Revised based on today's
8760 feedback. The most important changes document what happens when
8761 you convert an out-of-range value to a signed integer type, and
8762 say that (sum < a) != (b < 0) reliably detects overflow when sum =
8765 * doc/autoconf.texi (Integer Overflow): Greatly expand and
8766 rewrite, taking notions from the recent discussion on the gcc and
8767 autoconf mailing lists; please see
8768 http://lists.gnu.org/archive/html/autoconf-patches/2006-12/msg00091.html
8769 and follow the many links.
8770 (Integer Overflow Basics, Signed Overflow Examples):
8771 (Optimization and Wraparound, Signed Overflow Advice):
8772 (Signed Integer Division): New sections.
8774 2006-12-28 Steven G. Johnson <stevenj@alum.mit.edu>
8776 * lib/autoconf/general.m4 (AC_DEFINE_TRACE): Don't include
8777 preprocessor macro arguments in traced name.
8778 * doc/autoconf.texi (Defining symbols): Document longstanding
8779 support for AC_DEFINE-ing macros with arguments, and document
8780 behavior when the same variable has multiple AC_DEFINEs.
8781 * lib/autoconf/fortran.m4 (_AC_FC_WRAPPERS): Revert to the
8782 old implementation which AC_DEFINEs the FC_FUNC and FC_FUNC_
8783 macros directly, giving much shorter and simpler code.
8785 2006-12-28 Malcolm Purvis <malcolmp@xemacs.org> (trivial change)
8787 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Insert a
8788 space before "$ac_configure_args" to prevent a 'config.status
8789 --recheck' failure if ac_configure_args doesn't contain a leading
8790 space. This works around a problem with the XEmacs configure.ac,
8791 which uses the (undocumented) ac_configure_args variable
8792 inconsistently with Autoconf.
8794 2006-12-22 Paul Eggert <eggert@cs.ucla.edu>
8796 * lib/autoconf/functions.m4 (AC_FUNC_MKTIME):
8797 Include <limits.h>, and use its INT_MAX to rewrite the
8798 j loop so that it does not overflow 'int'. Problem reported by
8800 <http://lists.gnu.org/archive/html/bug-gnulib/2006-12/msg00084.html>.
8801 Play it safe by shifting left by 1 rather than multiplying by 2,
8802 as GCC is less likely to optimize this away when the value
8803 is signed (when it assumes overflow leads to undefined behavior).
8804 Also, don't assume time_t uses two's complement.
8806 2006-12-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8808 * tests/torture.at (Substitute a 2000-byte string): Avoid using
8809 a 10kB long (multi-line) string literal, OpenServer 5.0.7 ksh
8810 dumps core on it. Report by Tim Rice.
8812 2006-12-18 Steven G. Johnson <stevenj@alum.mit.edu>
8814 * lib/autoconf/general.m4 (AC_ARG_ENABLE): Print help about
8815 --disable-option-checking to --help output even when
8816 AC_PRESERVE_HELP_ORDER is not used.
8817 (_AC_INIT_PARSE_ENABLE2): Print warnings using actual --enable or
8818 --with argument, rather than argument with [-.] replaced by
8820 * NEWS: Fix typo in previous change; the news was in the
8823 2006-12-18 Paul Eggert <eggert@cs.ucla.edu>
8825 * NEWS: Warnings are now generated by default for unknown
8826 --enable-* and --with-* options.
8827 * doc/autoconf.texi (Option Checking): Renamed from
8828 (Configure Option Checking). Tighten up the wording a bit.
8829 (External Software, Package Options): Cross-reference to Option
8830 Checking, and use this to shorten our section.
8831 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Prefer test -n
8832 "$x" to test "x$foo" != x.
8833 * lib/autoconf/status.m4 (AC_OUTPUT): Likewise.
8834 Don't warn if $enable_option_checking is "no".
8835 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Initialize
8836 ac_unrecognized_opts to the empty string.
8837 Don't echo the unrecognized opts, as this might mishandle
8838 backslashes or leading -.
8839 (AC_PRESERVE_HELP_ORDER): Put the --disable-option-checking
8840 usage next to the other --disable-FEATURE options in the
8843 2006-12-18 Steven G. Johnson <stevenj@alum.mit.edu>
8845 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS, _AC_INIT_PARSE_ARGS):
8846 (_AC_INIT_PARSE_ENABLE2, _AC_INIT_HELP, _AC_ENABLE_IF):
8847 Print warning for unrecognized --with and --enable options
8848 (AC_DISABLE_OPTION_CHECKING): New macro to disable warnings.
8849 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS, _AC_OUTPUT_SUBDIRS):
8850 Disable option checking when subdirs are configured.
8851 (AC_OUTPUT): If warnings are enabled, print warning about
8852 unrecognized --with and --enable options at the end of
8853 the configure output (as well as at the beginning).
8854 * doc/autoconf.texi (Option Checking): New node.
8855 Document new option warning functionality.
8857 2006-12-16 Eric Blake <ebb9@byu.net>
8859 * configure.ac (AC_INIT): Bump version, since 2.61a is released.
8860 * NEWS: Start news for current version.
8862 2006-12-15 Paul Eggert <eggert@cs.ucla.edu>
8864 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT):
8865 Define HAVE_GETMNTENT to 1, not to the empty string.
8866 Problem originally reported by Jochen Friedrich in
8867 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=403243>.
8869 This change prompted by a problem report by Andrey Simonenko in
8870 <http://lists.gnu.org/archive/html/bug-autoconf/2006-12/msg00026.html>.
8871 * doc/autoconf.texi (Defining Symbols): AC_DEFINE works for
8872 object-like macros only, in the traditional portable character
8874 * lib/autoconf/general.m4 (AC_DEFINE_TRACE_LITERAL):
8875 Warn about attempts to define things that are not identifiers.
8876 * lib/autoconf/fortran.m4 (_AC_FC_WRAPPERS): Rewrite to avoid
8877 awful hack that AC_DEFINEd macro names containing parentheses.
8879 2006-12-12 Paul Eggert <eggert@cs.ucla.edu>
8881 * doc/autoconf.texi: Undo some of the 2006-12-10 change. It was
8882 too drastic, even if Texinfo in theory requires it for info mode.
8884 (config.status Invocation): Renamed back from Recreating a
8886 (Obsolete config.status Use): Renamed back from Obsolete Recreation.
8887 (Autoconf 2.13): Renamed back from 20th-century Autoconf 2.
8889 2006-12-11 Paul Eggert <eggert@cs.ucla.edu>
8891 * NEWS: Version 2.61a.
8893 2006-12-11 Paul Eggert <eggert@cs.ucla.edu>
8894 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8896 * NEWS: Document changes with echo and printf, and the lack
8897 of limits on the total size of multi-line values of substituted
8898 variables, and the AC_FUNC_FSEEKO fix.
8900 2006-12-10 Paul Eggert <eggert@cs.ucla.edu>
8902 * doc/autoconf.texi (Writing Autoconf Input): Renamed from
8903 Writing configure.ac.
8904 (Autoconf Input Layout): Renamed from configure.ac Layout.
8905 (Recreating a Configuration): Renamed from config.status Invocation.

8912 * BUGS: Remove mention of VPATH problem, since it's now documented
8913 not to be a bug in the Autoconf build procedure itself, but rather
8914 a problem with the proprietary `make' programs.
8916 * doc/autoconf.texi (Build Directories): Add a cross reference
8919 * build-aux/config.guess, build-aux/config.sub, build-aux/texinfo.tex:

8929 * lib/autoconf/c.m4 (_AC_PROG_CC_C89): Also try -xc99=all, for Sun
8930 C 5.8 on Solaris 10. Using -xc99=all rather than -xc99 bypasses
8931 the buggy -xc99 option of Forte Developer 7 C on Solaris 9.
8933 2006-12-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8935 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Drop the
8936 `CEOF$ac_eof' special marker, the awk script cannot contain a
8937 line matching `^CEOF', so this is not needed any more.
8938 * tests/torture.at (Substitute a newline): Expose the `%!_!# '
8939 special marker in the test.
8941 2006-12-06 Stepan Kasal <kasal@ucw.cz>
8943 * tests/tools.at (autom4te preselections): Use `find -newer';
8944 remove one of the sleeps.
8946 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE): Make it
8947 more readable, using ...
8948 (_AC_INIT_PARSE_ENABLE2): ... this new helper macro.
8950 * doc/autoconf.texi (autoheader Invocation): Do not double-
8951 quote the parameter of `AH_BOTTOM' in the example.
8953 2006-12-05 Stepan Kasal <kasal@ucw.cz>
8955 * doc/autoconf.texi (Configuration Headers): Remove the
8956 example with multiple input files.
8957 (autoheader Invocation): Encourage `AH_BOTTOM', discouraging
8958 multiple input files.
8960 2006-12-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8962 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): When
8963 creating the awk substitution script, handle one input line at a
8964 time, so that the maximum length of a substituted (multi-line)
8965 value is not limited by the size of the sed pattern space.
8966 The trade-off is a slightly repetitive sed script.
8967 * doc/autoconf.texi (Limitations of Usual Tools): Branch labels
8968 can only have up to 7 characters, due to Solaris 10 /bin/sed.
8969 * tests/torture.at (Substitute a 2000-byte string): Increase the
8970 test with several long lines, they should not be caught by sed
8973 * tests/tools.at (autom4te preselections): New test, to flag
8974 entries missing from autom4te.cfg.
8975 Report by David Byron <dbyron@hheld.com>.
8977 * tests/torture.at (Substitute a 2000-byte string): Actually use
8978 AC_PROG_AWK, so the last change works as intended.
8979 (Substitute and define special characters): Likewise.
8980 (Substitute a newline): Likewise.
8982 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Use `$AWK'
8983 instead of `awk' consistently.
8984 (_AC_OUTPUT_CONFIG_STATUS): Initialize $AWK.
8985 * tests/torture.at (Torturing config.status): Test both the
8986 result of AC_PROG_AWK and plain awk.
8987 (Substitute a 2000-byte string): Likewise.
8988 (Substitute and define special characters): Likewise.
8989 (Substitute a newline): Likewise.
8991 2006-12-04 Paul Eggert <eggert@cs.ucla.edu>
8993 * lib/autoconf/functions.m4 (AC_FUNC_FSEEKO): Check that fseeko
8994 can be assigned to a function pointer. Problem reported by
8995 Peter Palfrader in <http://bugs.debian.org/401377>. Based on
8996 part of a patch by Ralf Wildenhues in that same bug report.
8998 2006-12-01 Paul Eggert <eggert@cs.ucla.edu>
9000 * tests/mktests.sh (ac_exclude_list): Exclude AC_FUNC_SETVBUF_REVERSED.
9001 * tests/semantics.at (AC_FUNC_SETVBUF_REVERSED): New test.
9003 2006-12-01 Eric Blake <ebb9@byu.net>
9005 * lib/autoconf/c.m4 (AC_LANG_INT_SAVE): Avoid newline, to aid in
9006 cross-compiling from cygwin to mingw.
9007 Reported by Bob Rossi. This resurrects the 2000-11-30 patch to
9008 aclang.m4, which was mistakenly removed in the 2001-09-17 patch
9009 to lib/autoconf/c.m4.
9011 2006-12-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9013 * lib/m4sugar/m4sh.m4 (_AS_ECHO_PREPARE): Use a longer test
9014 string for more reliable failure. Wrap the entire test that
9015 causes the broken Solaris printf to dump core, in a subshell,
9016 so the segmentation fault message is reliably suppressed.
9017 Fix shell expansion errors by using /usr/ucb/echo always;
9018 avoid an error on systems without it by another subshell.
9019 Avoid m4 expansion of `$1'. Set the zeroth argument of the
9020 subshell-$as_echo to `as_echo', for better error message.
9022 2006-11-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9024 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): If `BASH_ARGV' or
9025 `BASH_SOURCE' contain a newline, set them to empty, as they may
9028 2006-11-27 Paul Eggert <eggert@cs.ucla.edu>
9030 Turn AC_FUNC_SETVBUF_REVERSED into a noop. It's been obsolete for
9031 years and is too hard to maintain now. The last straw was
9032 reported by Jerker Baeck in
9033 <http://lists.gnu.org/archive/html/autoconf/2006-11/msg00102.html>.
9034 * NEWS: AC_FUNC_SETVBUF_REVERSED is now obsolete.
9035 * doc/autoconf.texi (Particular Functions): Move
9036 AC_FUNC_SETVBUF_REVERSED from here...
9037 (Obsolete Macros): ... to here. Say that it does nothing now.
9038 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
9039 Turn into (almost) a no-op.
9041 * lib/autoconf/c.m4 (AC_PROG_GCC_TRADITIONAL, AC_C_CONST):
9043 Do not recommend via AN_FUNCTION, AN_IDENTIFIER, or AN_HEADER.
9044 These macros are obsolescent and new applications shouldn't need them.
9045 * lib/autoconf/functions.m4 (AC_FUNC_CLOSEDIR_VOID, AC_REPLACE_FNMATCH):
9046 (AC_FUNC_GETLOADAVG, AC_FUNC_GETPGRP, AC_FUNC_MEMCMP):

9051 (AC_HEADER_STDC, AC_HEADER_SYS_WAIT, AC_HEADER_TIME): Likewise.
9052 * lib/autoconf/types.m4 (AC_STRUCT_TM): Likewise.
9054 * doc/autoconf.texi (Setting Output Variables): Mention that
9055 @VAR1@VAR2 has unspecified behavior. Problem reported by
9057 * NEWS: Mention this.
9059 * Makefile.am: Put only a single '#' into the copyright notice,
9060 so that it's also present in the output file. Standardize wording
9061 in makefile copyright notices to match GNU coding standards.
9062 * bin/Makefile.am: Likewise.

9075 2006-11-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9077 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Fix error
9078 in the sed script that mangles the awk script: delete up to the
9079 first exclamation mark only.
9080 * tests/torture.at (Substitute and define special characters):
9083 2006-11-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9085 Rewrite config files generation: avoid quadratic growth in
9086 the number of substituted variables by using awk instead of sed
9087 for the bulk of the substitutions.
9088 * NEWS: Mention this.
9089 * doc/autoconf.texi (Setting Output Variables): `|#_!!_#|' is also
9090 forbidden in the output (and thus input) file.
9091 * lib/autoconf/status.m4 (_AC_AWK_LITERAL_LIMIT): New macro.
9092 (_AC_OUTPUT_FILES_PREPARE): Instead of several sed scripts,
9093 generate just one large awk script for substitutions,
9094 eliminating much of the earlier complexity, while adding some
9095 new complexity. Only expand the substitution templates at
9096 configure time, for smaller configure script size. If
9097 _AC_SUBST_FILES are used, test 'awk' for working getline support
9098 at config.status time. If absent, interpolate through the
9099 shell. The awk script was written with much help
9100 from Paolo Bonzini and Paul Eggert.
9101 (_AC_SED_CMD_NUM, _AC_SED_DELIM_NUM, _AC_SED_FRAG): Removed.
9102 (_AC_SED_FRAG_NUM): Likewise.
9103 (_AC_SUBST_CMDS): Renamed from...
9104 (_AC_SED_CMDS): ...this.
9105 (_AC_OUTPUT_FILE): Use _AC_SUBST_CMDS.
9106 * tests/torture.at (Substitute a 2000-byte string): Also
9107 substitute a line with 1000 words, and a variable with several
9109 (Substitute and define special characters): Test awk special
9110 characters, and put substitution input strings `@foo@' in the
9111 output, to test that no recursion happens; test several other
9112 combinations from Paolo Bonzini.
9114 2006-11-25 Paul Eggert <eggert@cs.ucla.edu>
9116 * lib/autotest/general.m4 (AT_INIT): Undo recent changes
9117 that replaced echo with AS_ECHO where this wasn't necessary.
9118 Problem reportd by Ralf Wildenhues.
9119 * lib/m4sugar/m4sh.m4 (_AS_ECHO_PREPARE): Port to Solaris 7,
9120 where "/usr/bin/printf '%s\n' S" dumps core if S is long.
9121 This is Sun bug 4206210. Problem reportd by Ralf Wildenhues.
9123 2006-11-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9125 * lib/freeze.mk (GREP): Removed, no need to initialize this.
9127 2006-11-21 Paul Eggert <eggert@cs.ucla.edu>
9129 * doc/autoconf.texi (Limitations of Usual Tools): Don't claim
9130 that traditional Awk lacks 3-arg "split". It has it.
9131 Mention that FS must be a single character, and a few other
9132 99-byte limits of traditional Awk.
9133 Mention that if (i in a) doesn't work with traditional Awk.
9135 2006-11-18 Paul Eggert <eggert@cs.ucla.edu>
9137 * tests/autotest.at (BSx641-newline in command):
9138 (BS-BS-newline in command, BSx640-newline in command):
9139 (Newline-CODE-BS-newline in command):
9140 (Single-quote-BS-newline in command):
9141 (Single-quote-newline-BS-newline in command):
9142 Use printf '%s\n' instead of echo, for portability to hosts
9143 where echo interprets backslashes. This will break on hosts
9144 that lack printf, but for now let's assume all such hosts
9145 are dead (if not, we should get reports of test failures).
9147 2006-11-17 Paul Eggert <eggert@cs.ucla.edu>
9149 'echo' has some portability problems, when given a first argument
9150 with a leading '-', or when given any argument containing '\'.
9151 Avoid using 'echo' in these cases.
9152 * bin/Makefile.am $(bin_SCRIPTS): Rewrite to avoid 'echo' entirely.

9155 * lib/autotest/general.m4 (AT_INIT): Likewise.
9156 * bin/autoconf.as: Use AS_ECHO rather than plain echo, when the

9176 (AS_TR_SH, AS_TR_CPP, AS_VAR_GET): Likewise.
9177 * bin/autoconf.as: Redo verbose flag implementation, as the old
9178 scheme wouldn't work with AS_ECHO.

9180 * lib/autoconf/general.m4 (AC_MSG_RESULT, AC_MSG_RESULT_UNQUOTED):
9181 Don't use ECHO_T, since ECHO_N is now reliable.
9182 * lib/autotest/general.m4 (AT_INIT): Likewise.
9183 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Use sed "$script"
9184 rather than using a here-document to put the script into a file.
9185 (_AC_DO_ECHO): Hoist the eval out of the echo, so that we can
9187 * lib/m4sugar/m4sh.m4 (AS_VAR_GET): Likewise.
9188 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Use
9189 AS_ECHO_N rather than ECHO_N and ECHO_C. This doesn't fix any
9190 bug, but we might as well stop using ECHO_N and ECHO_C internally.
9191 * lib/autotest/general.m4 (AT_SETUP): Likewise.

9193 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
9194 (_AC_OUTPUT_MAIN_LOOP): Rework echo so that it has just one
9195 operand, as AS_ECHO requires. Avoid double file name expansion.
9196 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Invoke _AS_ECHO_PREPARE.
9197 Don't set as_nl, since _AS_ECHO_PREPARE does that now.
9198 (_AS_PREPARE): Comment that _AS_ECHO_N_PREPARE is just for user code.
9199 (AS_ECHO, AS_ECHO_N, _AS_ECHO_PREPARE): New macros.
9200 * tests/c.at (AC_PROG_CPP without warnings, AC_PROG_CPP via CC):
9201 Double-quote strings that would otherwise contain M4 comments.
9202 * tests/m4sh.at (AS_ECHO and AS_ECHO_N): New test.
9204 * configure.ac (AC_INIT): Bump to 2.61a.
9207 2006-11-17 Paul Eggert <eggert@cs.ucla.edu>
9211 * configure.ac (AC_INIT): Bump to 2.61.
9214 * tests/autotest.at (Macro with backslash in a test title):
9215 Comment out for now, as this tests neither fails nor passes
9216 reliably. Problem reported by Ralf Wildenhues.
9218 2006-11-16 Paul Eggert <eggert@cs.ucla.edu>
9220 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE): Fix some typos
9221 in previous change, which caused test failures.
9223 2006-11-16 Stepan Kasal <kasal@ucw.cz>
9225 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Factor out
9226 code for --enable, --disable, --with, and --without to...
9227 (_AC_INIT_PARSE_ENABLE): ... a new macro.
9228 * doc/autoconf.texi (Package Options):

9233 Import these changes from config via gnulib:
9235 2006-11-15 Ben Elliston <bje@gnu.org>
9237 From Josselin Mouette <joss@debian.org>:

9290 first argument may also contain dots.
9292 2006-11-09 Paul Eggert <eggert@cs.ucla.edu>
9294 * tests/mktests.sh (ac_exclude_list): Exclude AC_PROG_CXX_C_O, for
9295 benefit of platforms like Solaris+GCC where it is common to have a
9296 non-working g++ installation.

9303 and non-portable sed scripts, and use $CONFIG_SHELL when invoking
9306 2006-11-08 Paul Eggert <eggert@cs.ucla.edu>
9308 * lib/autoconf/types.m4 (AC_TYPE_LONG_LONG_INT): Set
9309 ac_cv_type_long_long_int to 'yes' instead of 'cross-compiling'.
9310 Imported from a similar patch to gnulib by Bruno Haible.
9312 2006-11-08 Paul Eggert <eggert@cs.ucla.edu>
9314 * NEWS: New macros AC_C_FLEXIBLE_ARRAY_MEMBER, AC_C_VARARRAYS.

9330 2006-10-26 Joel E. Denny <jdenny@ces.clemson.edu>
9331 and Stepan Kasal <kasal@ucw.cz>
9333 Handle special characters in test case titles correctly.
9334 * lib/autotest/general.m4 (AT_INIT): M4-quote and AS_ESCAPE AT_help_all
9336 (AT_SETUP): M4-quote and AS_ESCAPE the title properly everywhere.
9337 * tests/autotest.at (AT_CHECK_AT_TITLE): Add EXPANDED-TITLE-TO-TEST
9338 argument. Extend to check titles printed by ./micro-suite and
9339 ./micro-suite -l and the title in micro-suite.log.
9340 (Backquote in a test title,
9341 Single-quote in a test title,
9342 Double-quote in a test title): Don't expect failure anymore.
9343 (Backslash in a test title): Put a non-whitespace character after the
9344 backslash so that Bourne shells might actually see it as an escape
9346 (Brackets in a test title,
9347 Pound in a test title,
9348 Comma in a test title,
9349 Quoted Macro in a test title,

9352 (Macro with backquote in a test title,
9353 Macro with double-quote in a test title,
9354 Macro with backslash in a test title): New tests expected to fail.
9355 * tests/torture.at (#define header templates): M4-quote this title in
9356 AT_SETUP call so that no M4 code is commented inadvertently somewhere.
9357 The visible effect was a stray [] in the testsuite output.
9359 2006-10-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9361 * doc/autoconf.texi (Limitations of Builtins): Do not invoke
9362 `trap ... 0' inside a function, for AIX sh.
9364 2006-10-26 Paul Eggert <eggert@cs.ucla.edu>
9366 * tests/base.at (AC_COMPUTE_INT): Test **0** rather than 1 / 0,
9367 since powerpc-apple-darwin8-gcc-4.0.1 (Apple Computer, Inc. build
9368 5363) simply issues a warning when dividing by zero at compile
9369 time. Problem reported by Elias Pipping.
9371 2006-10-26 Eric Blake <ebb9@byu.net>
9374 * doc/autoconf.texi (Evaluation Macros): Improve the example to
9375 show effect on macros that expand with commas.
9376 Reported by Joel E. Denny.

9400 2006-10-24 Paul Eggert <eggert@cs.ucla.edu>
9402 * lib/autoconf/specific.m4 (_AC_SYS_LARGEFILE_MACRO_VALUE):
9403 If FUNCTION-BODY is nonempty, use AC_LINK_IFELSE rather than
9404 AC_COMPILE_IFELSE, to work around problem with OSF/1 4.0F fseeko
9405 reported by Nelson H. F. Beebe for Coreutils 6.4.
9407 * tests/tools.at (autoconf --trace: user macros): Remove test
9408 for tracing multiline macros, since m4 1.4.7a uses a different
9409 way to number lines. Problem reported by Ralf Wildenhues.

9436 * doc/autoconf.texi (Caching Results): Likewise.
9437 * lib/autoconf/general.m4 (_AC_CACHE_CHECK_INT): Renamed from
9438 AC_CACHE_CHECK_INT, since it's no longer public.
9439 * lib/autoconf/types.m4: All uses of AC_CACHE_CHECK_INT changed.
9440 * tests/base.at (AC_COMPUTE_INT): Test this, not AC_CACHE_CHECK_INT.

9487 (Imported from Automake.)
9488 * build-aux/install-sh (posix_mkdir): Reject FreeBSD 6.1 mkdir -p -m,
9489 which incorrectly sets the mode of an existing destination
9490 directory. In some cases the unpatched install-sh could do the
9491 equivalent of "chmod 777 /" or "chmod 0 /" on a buggy FreeBSD
9492 system. We hope this is rare in practice, but it's clearly worth
9493 fixing. Problem reported by Alex Unleashed in
9494 <http://lists.gnu.org/archive/html/bug-autoconf/2006-10/msg00012.html>.
9495 Also, don't bother to check for -m bugs unless we're using -m;
9496 suggested by Stepan Kasal.

9545 added to the template can get mangled.
9547 2006-10-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9549 * lib/autoconf/functions.m4 (AC_FUNC_OBSTACK): In the test,
9550 include the default headers, and redefine obstack_chunk_alloc
9551 and obstack_chunk_free. Fixes false failure with glibc.
9553 2006-10-12 Paul Eggert <eggert@cs.ucla.edu>
9555 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Set as_executable_p,

9568 the NonStop platform.
9569 * doc/autoconf.texi (Posix Variants): Likewise.
9570 * lib/autoconf/specific.m4 (AC_USE_SYSTEM_EXTENSIONS): Likewise.
9572 * lib/m4sugar/m4sh.m4 (AS_TEST_X): New macro.
9573 (AS_EXECUTABLE_P): Use as_test_x rather than as_executable_p.
9574 (_AS_TEST_PREPARE): Set as_test_x rather than as_executable_p.
9575 Use a better substitute, by inspecting the output of "ls"
9576 rather than just using ":".
9577 * lib/autoconf/general.m4 (_AC_LINK_IFELSE): Use AS_TEST_X
9578 rather than AS_EXECUTABLE_P, since we needn't worry about
9579 non-regular files here.
9581 * NEWS: Autoconf-generated shell scripts no longer export BIN_SH,
9582 due to configuration hassles with this. See Tonya Underwood's report
9583 <http://lists.gnu.org/archive/html/bug-autoconf/2006-10/msg00003.html>.

9594 * lib/m4sugar/m4sh.m4 (AS_BOURNE_COMPATIBLE): Move the
9595 initialization which is not inherited through the environment
9596 (_AS_BOURNE_COMPATIBLE): ... to this new macro.
9597 (_AS_RUN): Call _AS_BOURNE_COMPATIBLE, not AS_BOURNE_COMPATIBLE.

9602 problems with mkdir -p -m.
9604 2006-10-06 Paul Eggert <eggert@cs.ucla.edu>
9606 * lib/autoconf/c.m4 (_AC_PROG_PREPROC_WORKS_IFELSE): Remove
9607 comment about ac_cpp_err; it was incorrect, and anyway
9608 ac_cpp_err is being removed below.
9609 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE): Don't
9610 set ac_cpp_err to 'yesyes' if preproc_warn_flag and werror_flag
9611 are both 'yes'. In fact, don't bother setting ac_cpp_err at all;
9613 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't log our funky tests
9614 with werror_flag and conftest.err and so forth. This is more
9615 compatible with how _AC_PROG_PREPROC_WORKS_IFELSE behaves,
9616 and anyway the user shouldn't normally want to see this gorp logged.
9617 Problem reported by Ralf Wildenhues.
9618 * lib/autoconf/lang.m4 (AC_LANG_WERROR): werror_flag's default is
9619 empty, not 'no', since the rest of the code uses 'test -z'.
9621 2006-10-04 Paul Eggert <eggert@cs.ucla.edu>
9623 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE):
9624 Use a single call to AC_DO_TOKENS rather than multiple, for
9626 (_AC_LINK_IFELSE): Test that resulting file is executable.
9627 Problem reported by mwoehlke in
9628 <http://lists.gnu.org/archive/html/bug-coreutils/2006-10/msg00048.html>.
9630 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Use "test -x /" rather
9631 than creating a file to use with test -x; this is much faster.
9633 2006-10-02 Bruno Haible <bruno@clisp.org>
9635 * lib/autom4te.in (Automake-preselections): Add
9636 AM_GNU_GETTEXT_INTL_SUBDIR, for automake 1.10.
9638 2006-09-27 Stepan Kasal <kasal@ucw.cz>
9640 * doc/autoconf.texi (Writing testsuite.at): Fix a typo: for
9641 standard error, `experr' should be used, not `expout'.
9643 2006-09-26 Paul Eggert <eggert@cs.ucla.edu>
9645 * lib/autoconf/functions.m4 (AC_FUNC_FSEEKO): Don't compile the
9646 fseeko testing program twice; just use the earlier result.
9647 * lib/autoconf/specific.m4 (_AC_SYS_LARGEFILE_MACRO_VALUE):
9648 Set cache var to 'unknown' (not 'no') if leaving the macro unset
9649 still doesn't let the program compile.
9650 (AC_SYS_LARGEFILE): Test for _LARGE_FILES only if earlier tests
9653 * lib/autoconf/functions.m4: Fix problems reported by Ralf Wildenhues.
9654 (AC_FUNC_ERROR_AT_LINE): Don't bother to check for error.h. Just
9655 include it, without including anything else.
9656 (AC_FUNC_FSEEKO): Avoid gcc -Wall warnings about constant
9658 (AC_FUNC_STRNLEN): Require AC_USE_SYSTEM_EXTENSIONS.

9662 * lib/autoconf/functions.m4 (AC_FUNC_ERROR_AT_LINE): Check for
9663 `error.h', and include it, for a `error_at_line' prototype.
9664 Use a nonempty format string in the link test.
9665 * lib/autoconf/functions.m4 (AC_FUNC_WAIT3): Include <sys/wait.h>,
9666 for a declaration of wait3.

9672 can apply to constants too, and that it checks for macro defns.
9673 * lib/autoconf/general.m4 (AC_CHECK_DECL): Assume C89 or better,

9675 values. Problem reported by Ralf Wildenhues.

9837 except the first two arguments are reversed.

9890 broken lex libraries like native ia64-hp-hpux11.22; see
9891 <http://sources.redhat.com/ml/binutils/2003-12/msg00337.html>, and
9892 work around the problem by preferring an empty LEXLIB to -lfl or
9893 -ll. Let the user set LEXLIB='' to indicate no library needed.

10124 more globally, since the 2006-06-30 patch didn't suffice. Problem
10125 reported by Keith Marshall. Also, don't bother with builddir2,
10126 since it shouldn't be needed any more.
10128 2006-07-07 Paolo Bonzini <bonzini@gnu.org>
10130 * doc/autoconf.texi (Generic compiler characteristics):

10149 * lib/autoconf/types.m4 (AC_TYPE_LONG_LONG_INT):
10150 Require that long long int be at least 64 bits wide. C99 requires
10151 this and enough programs depend on it so we should check for it.
10152 Bruno Haible reports in
10153 <http://lists.gnu.org/archive/html/bug-gnulib/2006-06/msg00286.html>
10154 that long long int is 32 bits wide with some nonstandard compilers.

10162 Problem reported by Keith Marshall in
10163 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00133.html>.
10165 2006-06-28 Paul Eggert <eggert@cs.ucla.edu>
10167 * doc/autoconf.texi: Be more consistent about using @acronym with
10168 "HP" and "HP-UX". Remove mention of OSF; the old version wasn't
10169 quite right (it talked about "OSF/Tru64", even though the
10170 operating systems were called OSF/1, Digital UNIX, and Tru64 UNIX,
10171 and it even mentioned "OSF 4"!) and at this point there's little
10172 reason to talk about OSF any more, since it died in 1994.
10173 (Specific Compiler Characteristics): Simplify example of
10174 negative-size array.
10175 (File Descriptors): Reorder to make the text flow better.
10176 Remove joke about "appreciate the various levels"; I didn't get it.

10183 2006-06-26 Stepan Kasal <kasal@ucw.cz>
10185 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Use -lX11, not
10186 -lXt in LIBS, idea from Karsten Hopp; this was due since
10189 2005-09-18 Paul Eggert <eggert@cs.ucla.edu>
10190 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Look for X11/Xlib.h
10191 and XrmInitialize rather than X11/Intrinsic.h and XtMalloc
10192 (which belong to Xt, not X itself). See Debian bug 327655.
10194 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10196 * configure.ac (AC_INIT): Bump to 2.60a.

10219 to document the whole `datarootdir' business a bit better.
10221 * tests/torture.at (datarootdir workaround): Extend test.
10222 Prompted by report by Alexandre Julliard.
10224 2006-06-22 Paul Eggert <eggert@cs.ucla.edu>
10226 * lib/autoconf/c.m4 (_AC_PROG_CC_C89): Check for C89 incompatibility

10236 2006-06-20 Paul Eggert <eggert@cs.ucla.edu>
10238 * NEWS: Use "M4" rather than "m4" when appropriate.
10239 Problem reported by Eric Blake.
10240 * doc/autoconf.texi: Likewise.
10241 Use @acronym around BSD, GCC, and GNU when appropriate.
10242 (Why GNU M4): Renamed from "Why GNU m4".
10243 (Redefined M4 Macros): Mention that Posix
10244 m4wrap takes only 1 argument, but GNU M4 1.4.x takes more.
10245 (Buffer Overruns): Mention size_t and ptrdiff_t as alternatives
10248 2006-06-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10250 * bin/autom4te.in (handle_output): Do not forbid the empty
10252 * tests/tools.at (autoconf: the empty token): New test.
10254 2006-06-20 Stepan Kasal <kasal@ucw.cz>
10256 * lib/m4sugar/m4sugar.m4 (m4_init): Merge the two m4_wrap
10257 calls, so that we do not care whether they are LIFO or FIFO;
10258 in the m4_wrap, do not check which diversion is the topmost
10259 one, just check that the stack is balanced at the end.
10260 * lib/m4sugar/m4sh.m4 (AS_INIT): We are going to change the
10261 base diversion forever--pop the previous diversion before
10262 opening the new one; consequently, remove the m4_wrap call.
10263 * lib/autotest/general.m4 (AT_INIT): Likewise.
10264 * tests/m4sugar.at: Do not use
10265 m4_wrap([m4_diversion_pop([..])]), for educational purposes.

10268 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10270 * NEWS: Document that m4wrap/m4_wrap might not be LIFO.
10271 * doc/autoconf.texi (Redefined M4 Macros): Likewise.
10272 Rework example of m4wrap token-pasting trouble so that it doesn't
10273 care whether it's LIFO or FIFO.
10274 Fix some "contrary to"s that are awkward in English.
10276 2006-06-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10278 * lib/autoconf/types.m4 (_AC_TYPE_INT): Set `$ac_cv_c_int$1_t'
10279 to `yes' instead of `int$1_t' if the type is found, for more
10280 consistent configure output (where $1 is the number of bits).
10281 (_AC_TYPE_UINT): Likewise for `uint$1_t'.
10282 Suggested by Bruno Haible.
10284 * lib/autoconf/types.m4 (_AC_TYPE_UNSIGNED_INT): Solaris 2.5.1
10285 needs _UINT8_T and _UINT64_T defines as well, to avoid clashes
10286 with system headers. Report by Bruno Haible.
10288 2006-06-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10290 * config/config.guess, config/config.sub: Sync from upstream.
10292 * bin/Makefile.am (autoconf.in): Use `--melt' for autom4te,
10293 in order to avoid picking up an older installed frozen m4sh.m4f.
10294 Besides an outdated shell startup, this could have been created
10295 by an earlier M4 version with incompatible frozen file format.
10297 2006-06-16 Paul Eggert <eggert@cs.ucla.edu>
10299 * README: Recommend m4 1.4.4 instead of 1.4.3..
10300 * doc/autoconf.texi: Likewise.
10301 (Special Chars in Names): Say that $(.FOO) is portable, as
10302 suggested by Stepan Kasal.
10303 (Installation Directory Variables, Build Directories):
10304 (Automatic Remaking, Subdirectories, Fortran Compiler):
10305 (Making testsuite Scripts, Defining Directories):
10306 Quote variable usages better.
10307 (Making testsuite Scripts): Add clean-local rule to makefile
10308 snippet, by Eric Blake.
10309 (Installation Directory Variables): Fix table item font.
10310 Reword slightly to clarify. Generalize advice about
10311 not using special characters to include all file-related
10312 vars, not just VPATH.
10313 (Special Chars in Variables): Warn about special characters in
10315 (Assignments): Clarify default-value example as suggested by
10317 <http://lists.gnu.org/archive/html/autoconf-patches/2006-06/msg00072.html>.
10318 (Special Shell Variables): Note leading ./ or ../, as suggested
10320 (Limitations of Builtins): Under cd, warn about CDPATH.
10321 (The Make Macro MAKEFLAGS): Untabify. Problem reported by
10324 2006-06-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10326 * doc/autoconf.texi (Configuration Actions): Remove duplicate
10327 `@var', for texi2html.
10328 (Systemology): Some more word wrapping, for DVI output.
10329 (autom4te Invocation): The short option for `--melt' is `-M',
10332 2006-06-15 Paul Eggert <eggert@cs.ucla.edu>
10334 * doc/autoconf.texi: More formatting and English tweaks,
10335 many suggested by Ralf Wildenhues.
10336 Reword to avoid "@code{...}'s" and the like, since it's ugly
10337 with Emacs info mode. discontents -> woes.
10338 Put a few "will"s back. time stamp -> timestamp.
10339 side-effect -> side effect.
10341 2006-06-14 Paul Eggert <eggert@cs.ucla.edu>
10343 * doc/autoconf.texi (Initializing configure, Shell Substitutions):
10344 Warn about $@ not persisting. Problem reported by Julien Danjou in
10345 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=372179>.
10346 (Special Chars in Names): Renamed from Leading _ in Macro Names.
10347 Mention other special chars, too.
10349 2006-06-14 Eric Blake <ebb9@byu.net>
10351 * doc/autoconf.texi (The Make Macro MAKEFLAGS): New node.
10353 2006-06-13 Paul Eggert <eggert@cs.ucla.edu>
10355 * doc/autoconf.texi: Some systematic minor improvements, as
10356 follows. Use "makefile" when talking about makefiles
10357 generally (which might be named "makefile" or "Makefile" or even
10358 "foo.mk"), "Makefile" when talking about a specific makefile
10359 called "Makefile". This unclutters the text from weird quotes
10360 (e.g., "`Makefile's" in info mode). Similarly, use "@var{foo}
10361 values" rather than "@var{foo}s" and similar constructs containing
10362 "}s". Use "Make rules" rather than "Makefile rules". Minor
10363 English-language improvements. Change the prefix "sub-" to "sub"
10365 Put blank lines around examples more consistently.
10366 Avoid "rather" and "very" as intensifiers.
10367 Avoid "will" as an auxiliary.
10368 (Limitations of Make): Split this node into....
10369 (Portable Make, $< in Ordinary Make Rules, Failure in Make Rules):
10370 (Leading _ in Macro Names, Backslash-Newline-Newline):
10371 (Backslash-Newline Comments, Long Lines in Makefiles):
10372 (Macros and Submakes, The Make Macro SHELL, Comments in Make Rules):
10373 (obj/ and Make, make -k Status, VPATH and Make):
10374 (VPATH and Double-colon, $< in Explicit Rules):
10375 (Automatic Rule Rewriting, OSF/Tru64 Directory Magic):
10376 (Make Target Lookup, Single Suffix Rules, Timestamps and Make):
10377 New nodes, resulting from splitup of Limitations of Make.
10378 All cross-references changed. Raise the top node from
10379 a section to a chapter, and all subnodes accordingly.
10380 Redo the introductory wording to match the new organization.
10381 (Installation Directory Variables): Use an example that is
10382 closer to what Autoconf actually does. Mention that VPATH's
10383 value should not contain metacharacters or white space.
10384 (Fortran Compiler): Fix a VPATH bug in an example.
10385 (Leading _ in Macro Names): Mention that this problem is no longer
10386 of practical concern.
10387 (VPATH and Make): Reword the advice to make it clearer
10388 that Autoconf and Automake support VPATH in non-GNU make, but
10389 many packages have bugs in this area.
10390 ($< in Explicit Rules): Refer to Build Directories rather
10391 than using a (non-VPATH-safe) example.
10392 (Automatic Rule Rewriting): Mention the sort of disaster that
10393 can ensue with Solaris-style rule rewriting with VPATH.
10395 2006-06-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10397 * doc/install.texi (Compilers and Options): Weaken the
10398 suggestion to use GNU make for VPATH builds.
10400 * lib/autom4te.in (Automake-preselections): Add AM_PROG_CXX_C_O,
10401 AM_PROG_F77_C_O, AM_PROG_FC_C_O, AC_FC_SRCEXT, AC_FC_FREEFORM.
10403 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Fix M4 quotation
10404 in regular expression.
10406 2006-06-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10408 * doc/autoconf.texi (Installation Directory Variables):
10409 Drop extra @samp from `@table @samp' item.
10410 (Limitations of Usual Tools): Comment fix.
10411 Do not nest @samp just to point to other table items.
10412 (Writing testsuite.at) <AT_CHECK>: The second argument to
10413 `@dvar' is already @samp'ed.
10414 (Making testsuite Scripts) <AC_CONFIG_TESTDIR>: Likewise,
10415 do not use @var in the second argument.
10417 2006-06-07 Paul Eggert <eggert@cs.ucla.edu>
10419 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Look for
10420 $as_shell.exe too. Problem reported by Andreas Buening in
10421 <http://lists.gnu.org/archive/html/autoconf/2006-06/msg00038.html>.
10423 2006-06-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10425 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA): Work around
10426 `unused variable' compiler warning, for `-Wall -Werror'.
10427 Reported by Jaap Haitsma in
10428 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00012.html>.
10430 2006-06-06 Paul Eggert <eggert@cs.ucla.edu>
10432 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Remove core file, in
10433 case the compiler dumps core. Problem reported for
10434 OpenServer 5.0.7 by Tim Rice in
10435 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00019.html>.
10436 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE):
10439 2006-06-06 Tim Rice <tim@multitalents.net>.
10441 * lib/freeze.mk: Quiet check-forbidden-patterns so the string
10442 "ERROR" only shows up in "make check" output if there is an
10445 2006-06-06 Eric Blake <ebb9@byu.net>
10447 * tests/tools.at (automatically allowed tokens): Fix typo.
10449 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
10451 * NEWS: Don't blame non-GNU VPATH compatibility issues on Automake.
10453 * doc/autoconf.texi (Integer Overflow): Mention that INT_MIN % -1
10454 typically overflows on x86 CPUs, even though the C standard
10455 requires otherwise.
10457 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10459 * configure.ac (AC_INIT): Bump to 2.59e.
10462 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10466 * config/texinfo.tex: Sync from upstream.
10468 * bin/autoreconf.in: Trace `LT_CONFIG_LTDL_DIR'; if it has been
10469 seen, invoke libtoolize with `--ltdl' argument.
10470 * lib/autom4te.in (Autoreconf-preselections): Adjust.
10472 Suggested by Eric Blake.
10474 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
10476 * NEWS: Whoops! AC_FUNC_STRNLEN isn't obsolescent. Problem
10477 reported by Ralf Wildenhues.
10478 * doc/autoconf.texi (AC_FUNC_STRNLEN): Likewise.
10480 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10484 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
10486 * doc/autoconf.texi: Modernize some of the references to Solaris.
10488 2006-06-05 Stepan Kasal <kasal@ucw.cz>
10490 * lib/m4sugar/m4sugar.m4 (m4_require): Modify the error
10491 message issued by AC_REQUIRE.
10492 * tests/m4sugar.at: Check m4_require's error message.
10493 * tests/base.at: Check AC_REQUIRE's error message.
10494 * tests/local.at (AT_CHECK_M4): New macro, almost identical
10496 (AT_CHECK_AUTOM4TE): ... which is now a thin wrapper around
10498 (AT_CHECK_AUTOCONF): Use AT_CHECK_M4; no longer support
10499 `expout' as the last parameter.
10500 * tests/tools.at: Adapt to the above change.
10502 2006-06-04 Stepan Kasal <kasal@ucw.cz>
10504 * doc/autoconf.texi (Limitations of Usual Tools): Correct
10505 information about race-free implementations of mkdir.
10507 2006-06-04 Eric Blake <ebb9@byu.net>
10509 * bin/autoreconf.in (help): Document M4 environment variable.
10510 * bin/autoconf.as (Usage): Likewise.
10511 * bin/autom4te.in (help): Likewise.
10512 * doc/autoconf.texi (autom4te Invocation): Likewise.
10514 2006-06-04 Paul Eggert <eggert@cs.ucla.edu>
10516 * NEWS: GNU make now recommended for VPATH builds.
10517 Mention that some macros are now documented to be obsolescent.
10518 * doc/autoconf.texi:
10519 Prefer "current" to "modern" to describe
10520 currently-used (albeit perhaps old-fashioned) hosts.
10521 Mention which ancient features no longer need to be worried about.
10522 setgid -> set-group-ID
10523 setuid -> set-user-ID (these are the Posix terms)
10524 Fix some misuses of "only".
10525 (AC_C_BACKSLASH_A, AC_C_CONST, AC_C_PROTOTYPES):
10526 (AC_C_STRINGIZE, AC_C_VOLATILE, AC_FUNC_CLOSEDIR_VOID):
10527 (AC_FUNC_GETPGRP, AC_FUNC_LSTAT, AC_FUNC_MEMCMP):
10528 (AC_FUNC_SELECT_ARGTYPES, AC_FUNC_SETPGRP):
10529 (AC_FUNC_SETVBUF_REVERSED, AC_FUNC_STAT, AC_FUNC_STRFTIME):

10532 (AC_HEADER_SYS_WAIT, AC_HEADER_TIME, AC_ISC_POSIX):
10533 (AC_PROG_GCC_TRADITIONAL, AC_STRUCT_TM):
10534 Mention that these macros are obsolescent.
10535 (Installation Directory Variables): shall -> should
10536 (File Descriptors): Mention that 0, 1, 2 might get reopened.
10537 Mention that it's now safe to use 3 and 4.
10538 (Limitations of Usual Tools): cp -r is now specified by Posix.
10539 Omit longwinded and obsolescent discussion of cp -f.
10540 Modernize discussion of expr, ls.
10541 (Limitations of Make): Modernize discussion of VPATH builds.
10542 Mention $? as a workaround in some cases.
10543 * doc/install.texi (Basic Installation):
10544 Mention "./configure; make; make install" first. Be more
10545 specific about why this file is generic. Remove unnecessary
10546 parens. Remove misleading "only". Remove obsolete advice
10547 about csh. Don't say "configure" takes awhile; say it
10548 might take a while. Suggest CFLAGS=-g rather than CFLAGS=-O2,
10549 and CC=c99 rather than CC=c89, as these are blessed by current
10550 Posix. Recommend GNU make if doing a VPATH build.
10552 2006-06-03 Paul Eggert <eggert@cs.ucla.edu>
10554 * doc/autoconf.texi: Use a consistent style "$ @kbd{...}" for
10555 examples involving shell prompts.
10557 2006-06-02 Stepan Kasal <kasal@ucw.cz>
10558 and Paul Eggert <eggert@cs.ucla.edu>
10560 * doc/autoconf.texi (Here-Documents): Add details about the
10561 pre-ksh93g bug. Reword slightly to make it clearer. Consistently
10562 use "here-documents" instead of "here documents".
10564 2006-06-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10566 * config/texinfo.tex, doc/standards.texi: Sync from upstream.
10568 2006-06-01 Paul Eggert <eggert@cs.ucla.edu>
10570 * doc/autoconf.texi (File System Conventions): Warn about ":"
10571 anywhere in directory names.
10573 2006-05-31 Paul Eggert <eggert@cs.ucla.edu>
10575 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be even more conservative
10576 about quoting the case statement, just in case.
10577 * doc/autoconf.texi (Here-Documents): Mention that the ksh bug
10578 was fixed in ksh93g; reported by Ralf Wildenhues.
10580 2006-05-31 Stepan Kasal <kasal@ucw.cz>
10582 * doc/autoconf.texi (System Services): Do not document
10583 overriding EXEEXT via ac_cv_exeext=ext.
10584 (Particular Programs) <AC_PROG_MKDIR_P>:
10585 Document that ${MKDIR_P} understands --.
10586 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Improve the
10589 2006-05-31 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10591 * lib/m4sugar/m4sh.m4 (_AS_DIRNAME_PREPARE): Guard against test
10592 argument with leading hyphen. Problem reported by Paul Eggert.
10594 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
10596 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be more conservative
10597 about quoting ac_try: quote all of it, if any of it seems suspicious.
10598 This means we don't have to worry about ${ or sed any more.
10599 Also, double-quote the case statement, to work around misuses via
10600 underquoting as reported by Ralf Wildenhues in
10601 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00169.html>.
10602 (_AC_EVAL_STDERR): Revert, since evidently some packages rely on this
10603 undocumented and dangerous macro.
10604 Problem reported by Ralf Wildenhues in
10605 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00168.html>.

10609 * lib/m4sugar/m4sh.m4 (_AS_DIRNAME_PREPARE): Check whether
10610 `dirname -- /' returns `/', for SunOS dirname scripts that escaped.
10611 Report by Sam Sirlin <sam@kalessin.jpl.nasa.gov>.
10613 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
10615 * lib/autoconf/general.m4: Revert AC_TRY_EVAL and AC_TRY_COMMAND,
10616 since evidently some packages rely on the old, broken behavior.
10617 Problem reported by Ralf Wildenhues in
10618 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00160.html>.
10619 (AC_TRY_EVAL, AC_TRY_COMMAND, _AC_EVAL): Go back to the
10620 pre-2006-05-26 definitions, but leave in the comments that
10621 these macros are dangerous and should not be used.
10622 (_AC_DO_ECHO): Renamed from _AC_EVAL_ECHO. All callers changed.
10623 (_AC_DO): Renamed from _AC_EVAL. All callers changed.
10624 (_AC_DO_STDERR): Renamed from _AC_EVAL_STDERR. All callers changed.
10625 (_AC_DO_VAR): Renamed from AC_TRY_EVAL.
10626 (_AC_DO_TOKENS): Renamed from AC_TRY_COMMAND.
10628 2006-05-29 Paul Eggert <eggert@cs.ucla.edu>
10630 * lib/autoconf/status.m4 (AC_OUTPUT_MAKE_DEFS): Rewrite to avoid
10631 the use of 'tr', since this is our only use of 'tr'.
10633 2006-05-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10634 and Paul Eggert <eggert@cs.ucla.edu>
10636 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE):
10637 Don't assume 'grep' works on long lines, since AIX grep doesn't.
10639 2005-05-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10641 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Do not use `grep' on
10642 the output file in the `${datarootdir}' test.
10644 2005-05-28 Stepan Kasal <kasal@ucw.cz>
10645 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10647 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If we have not seen
10648 mention of `datarootdir' in the input file(s), but literal
10649 `${datarootdir}' in the output file, and we haven't warned yet,
10650 then warn as well: the user may have (erroneously) used
10651 `AC_SUBST([mydatadir], [$datadir/my])' instead of the correct
10652 `AC_SUBST([mydatadir], ['${datadir}/my'])'.
10653 * tests/torture.at (datarootdir workaround): Extend this test.
10656 2006-05-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10657 and Paul Eggert <eggert@cs.ucla.edu>
10659 * doc/autoconf.texi (autoheader Invocation): The first argument to
10660 `AC_DEFINE_UNQUOTED' need not be a literal. Mention the
10661 alternatives and clear up the language a bit.
10663 2006-05-27 Paul Eggert <eggert@cs.ucla.edu>
10665 * NEWS: Reword notice for AC_TRY_COMMAND, AC_TRY_EVAL,
10666 ac_config_guess, ac_config_sub, ac_configure.
10667 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
10668 Fix typo that prevented an unnecessary space from being removed.
10669 Problems reported by Ralf Wildenhues in:
10670 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00143.html
10672 2006-05-26 Paul Eggert <eggert@cs.ucla.edu>
10674 * doc/autoconf.texi (Particular Programs, Limitations of Usual Tools):
10675 Use better wording to talk about AC_PROG_MKDIR_P's thread-safety.
10676 Don't use the term "thread-safe" to talk about mkdir race
10677 conditions, since the problem is more a process than a thread
10678 issue. Problem reported by Stepan Kasal in:
10679 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00088.html
10680 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Use code that mimics
10681 the test for 'install' more closely. Look at MKDIR_P first.
10682 Look in the PATH, and at /opt/sfw/bin.
10683 Look for a 'gmkdir' program as well (Solaris 10 /opt/sfw/bin/gmkdir).
10684 Don't bother to try mkdir -p, since we already check mkdir --version;
10685 just look at the version number. (There's no easy way to check
10686 for race-free implementations.)
10687 * tests/tools.at (autoconf: subdirectories): Adjust to above
10688 changes, since MKDIR_P now might end in "/mkdir -p".
10690 * doc/autoconf.texi (autoheader Invocation): Mention that the
10691 first arg of AC_DEFINE_UNQUOTED must be a literal.
10692 Problem reported by Ben Pfaff in
10693 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00090.html>.
10695 * NEWS: Mention that AC_TRY_COMMAND and AC_TRY_EVAL may be removed.
10696 * doc/autoconf.texi (Special Chars in Variables): New section.
10697 (Preset Output Variables): Warn about special chars in CPPFLAGS.
10698 (Installation Directory Variables): Quote $(datadir) better.
10699 (Limitations of Builtins): Describe some of eval's trickiness.
10701 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Simplify quoting.
10702 * lib/autoconf/fortram.m4 (_AC_PROG_FC_V_OUTPUT): Likewise.
10703 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Put leading space
10704 in front of every arg, not just trailing args. Quote apostrophes.
10705 (_AC_EVAL_ECHO): New macro.
10706 (_AC_EVAL, AC_EVAL_STDERR): Use it. Quote arg of eval.
10707 (AC_TRY_EVAL, AC_TRY_COMMAND): Mention that these macros might get
10709 (_AC_LINK_IFELSE): Use proper rule for shell continuation lines,
10710 exposed by quoting of eval argument. Put the command on line line
10712 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): Use eval more safely.
10713 (_AC_PATH_X, AC_PATH_X): Quote more safely.
10714 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Use eval more safely.
10715 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Don't use eval.
10716 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Minor style change.
10717 Handle special chars in prefix, ac_srcdir, ac_aux_dir.
10718 Use eval more safely.
10719 (_AC_OUTPUT_CONFIG_STATUS): Adjust to above changes.
10720 * lib/m4sugar/m4sh.m4 (AS_VAR_GET): Note that this API needs
10722 * tests/base.at (AC_TRY_COMMAND): Use proper rule for shell continuation

10726 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10728 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Drop the
10729 initialization of `ac_cv_exeext', do not override it if it was
10730 already set, unless it was set to `no', for compatibility with
10731 Autoconf-2.13, and comment this.
10732 Do not export `ac_cv_exeext', Libtool hasn't needed this for years.
10733 (_AC_COMPILER_EXEEXT_DEFAULT): Likewise, do not export it.
10734 (_AC_COMPILER_EXEEXT_WORKS, _AC_COMPILER_EXEEXT_CROSS): Typos.
10735 * doc/autoconf.texi (Compilers and Preprocessors) <EXEEXT>:
10736 Document that this test may be overridden by setting
10739 2006-05-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10741 Revert these two patches:
10743 2006-04-06 Eric Blake <ebb9@byu.net>
10744 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_O): Inside cache
10745 check, s/ac_exeext/ac_cv_exeext/. Fixes regression introduced
10748 2006-04-01 Stepan Kasal <kasal@ucw.cz>
10749 Clean up _AC_COMPILER_EXEEXT* macros.
10750 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't try to
10751 detect exeext, it will be done by _AC_COMPILER_EXEEXT_O; just set
10752 ac_file to the name of the default output file and call
10753 _AC_COMPILER_EXEEXT_WORKS. Move the definition of ac_files and the
10754 initial `rm' of the candidate files...
10755 (_AC_COMPILER_EXEEXT): ... here and simplify them. Moreover, use
10756 the same list in subsequent `rm' calls, and for the temporary
10757 redefinition of ac_clean_files; call _AC_COMPILER_OBJEXT at the end,
10758 and don't call the other _AC_COMPILER_EXEEXT_* macros directly, use...
10759 (_AC_COMPILER_EXEEXT_TESTS): ... this new macro.
10760 (_AC_COMPILER_EXEEXT_O): Don't export ac_cv_exeext, it's not needed (or
10761 no longer needed) by libtool. Make it a cache check.
10762 (_AC_COMPILER_EXEEXT_CROSS): Remove the comment, it was obviously
10763 copied here by mistake.
10764 (AC_NO_EXECUTABLES): Redefine _AC_COMPILER_EXEEXT_TESTS, not
10765 _AC_COMPILER_EXEEXT.
10766 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX, AC_PROG_OBJC): Do not call
10767 _AC_COMPILER_OBJEXT directly.
10768 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
10770 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10772 * doc/autoconf.texi (Limitations of Usual Tools) < sed (`t')>:
10773 Fix description of how the buggy `sed' works.
10775 2006-05-25 Noah Misch <noah@cs.caltech.edu>
10777 Sync from Automake:
10779 * lib/Autom4te/XFile.pm (lock): Allow EOPNOTSUPP, besides
10780 ENOLCK. Only mention `make -j' when applicable. Only raise
10781 fatal errors when `make -j' is involved. Improve error message.
10783 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10785 * doc/autoconf.texi (Here-Documents): We now know more about
10786 the variable expansion in here documents bug.
10787 Thanks to Tim Rice and Stepan Kasal.
10789 * doc/autoconf.texi (Making testsuite Scripts): Add an example
10790 how to use TESTSUITEFLAGS. Suggested by Eric Blake.
10792 2006-05-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10794 * tests/autotest.at (Multiline command from M4 expansion):
10795 No failure to be expected if the shell quotes newlines in
10796 commands in the `set -x' output. Report by Tim Rice.
10799 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
10801 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Don't use shell
10802 expansion in the here-documents used by config.status, as that
10803 runs afoul of the Korn shell version M-12/28/93d bug described in
10804 the Autoconf manual, and this in turn causes a Coreutils 5.95 build to
10805 fail as described by Tim Rice and diagnosed by Ralf Wildenhues in
10806 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00082.html>.
10808 2006-05-23 Jim Meyering <jim@meyering.net>
10810 * lib/autoconf/functions.m4 (AC_FUNC_LSTAT_FOLLOWS_SLASHED_SYMLINK):
10811 Fix typo introduced with 2006-04-02 change. It reversed the sense
10814 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
10816 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Simplify ac_dA and
10817 ac_dB slightly, to save bytes in the script.
10818 Max out at 50 lines, rather than 96; this is more likely
10819 (though not guaranteed) to avoid obscure 'sed' failures.
10821 2006-05-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10823 * lib/autotest/general.m4 (AT_INIT): UnixWare `tr' may interpret
10824 `tr -d -' as bad option argument. Work around this by deleting
10825 an unrelated character.
10826 Report by Tim Rice <tim@multitalents.net>.
10828 2006-05-22 Paul Eggert <eggert@cs.ucla.edu>,
10829 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
10830 Stepan Kasal <kasal@ucw.cz>
10832 * doc/autoconf.texi (Particular Programs): Do not promise that
10833 we always prefer the GNU version of the program, and that we
10834 search according to PATH; both rules can have exceptions.
10835 Update description of AC_PROG_GREP, AC_PROG_EGREP, AC_PROG_FGREP,
10836 AC_PROG_SED. Move descriptions of limitations
10837 to the Limitations of Usual Tools section.
10838 (Limitations of Usual Tools) <sed>: Mention script length
10839 limitations with Solaris /usr/ucb/sed.
10840 <grep>: Fix wording for empty alternative. Mention that -c and
10841 -l should not be combined, and that -E and -F should not be
10844 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
10845 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10847 * lib/autoconf/programs.m4 (AC_PROG_SED): Catch script length
10848 limits in Solaris 8 /usr/ucb/sed by testing a long script.
10850 2006-05-22 Stepan Kasal <kasal@ucw.cz>
10852 * doc/autoconf.texi (Defining Symbols): Literal parameter of
10853 AC_DEFINE is now passed to m4_pattern_allow.
10854 * NEWS: Mention that; likewise for AC_SUBST.
10855 * lib/autoconf/general.m4 (AC_DEFINE_TRACE_LITERAL): Pass
10856 the parameter to m4_pattern_allow.
10857 * tests/tools.at: Add a check for that.
10859 2006-05-22 Stepan Kasal <kasal@ucw.cz>
10861 * lib/autoconf/status.m4: Fix typos.
10863 2006-05-21 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10865 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Remove
10866 only the files that this macro generates.
10868 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
10870 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: For
10871 the HP-UX sed limitation of 99 commands, labels do not count.
10872 * lib/autoconf/status.m4 (_AC_SED_CMD_LIMIT): Mention that
10874 (_AC_OUTPUT_HEADER): Revert the change from 2006-05-19.
10876 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
10878 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT):
10879 Import the following fix from coreutils:
10881 2006-01-13 Jim Meyering <jim@meyering.net>
10883 Invoke AC_CHECK_FUNCS(getmntent) unconditionally so that tests of
10884 $ac_cv_func_getmntent (e.g., in gl_LIST_MOUNTED_FILE_SYSTEMS) need
10885 not double-quote uses of that variable, to accommodate the rare
10886 case in which getmntent is available in none of the libraries
10887 checked. This happens at least on FreeBSD 5.0.
10889 2006-05-20 Paul Eggert <eggert@cs.ucla.edu>
10891 * lib/autoconf/general.m4 (AC_CONFIG_AUX_DIRS): Bring back
10892 ac_config_guess, ac_config_sub, and ac_configure, since evidently
10893 some other programs unwisely rely on these undocumented vars.
10894 But put in warning comments about them.
10895 Problem reported by Ralf Wildenhues in
10896 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00068.html>.
10897 * NEWS: Document that these variables are intended to go away.
10899 2006-05-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10901 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): Require AC_PROG_CXX,
10902 and set the language to C++ (analogous to the equivalent Fortran
10905 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): New macro.
10906 * doc/autoconf.texi (C++ Compiler): Document it.
10907 * lib/autoconf/fortran.m4 (_AC_PROG_FC_C_O): Adjust comment.
10910 2006-05-19 Paul Eggert <eggert@cs.ucla.edu>
10912 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Fix off-by-one bug
10913 that caused config.status to generate 100-command sed scripts; the
10914 portable limit is 99.
10916 2006-05-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10918 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Name temporary
10919 variable `ac_d' instead of `d' to avoid infringing namespace.
10920 Report by Ralf Menzel.
10922 2006-05-18 Paul Eggert <eggert@cs.ucla.edu>
10924 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Don't prepend
10925 $ac_top_build_prefix to $MKDIR_P if it's just 'mkdir -p'.
10926 * tests/tools.at (autoconf: subdirectories): New test, taken from
10927 the corresponding problem report by Ralf Wildenhues in:
10928 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00053.html
10930 * lib/autoconf/functions.m4 (AC_REPLACE_FNMATCH, AC_FUNC_FNMATCH_GNU):
10931 Quote some uses of shell variables if they might suffer unexpected
10932 globbing. This doesn't fix all instances of quoting problems that
10933 I found, just the easy ones that look safe.
10934 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR, _AC_INIT_HELP):
10935 (AC_CONFIG_AUX_DIR, AC_CONFIG_AUX_DIR_DEFAULT, AC_CONFIG_AUX_DIRS):
10936 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST, AC_CANONICAL_TARGET):
10937 (AC_CACHE_LOAD, AC_CACHE_SAVE): Likewise.
10938 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF, _AC_PATH_X_DIRECT): Likewise.
10939 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Likewise.
10940 * lib/autoconf/status.m4 (_AC_OUTPUT_LINK, _AC_OUTPUT_SUBDIRS):
10942 * lib/autotest/general.m4 (_AC_INIT_PARSE_ARGS): Likewise.
10943 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Likewise.
10945 2006-05-18 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10947 * bin/autoreconf.in ($help): Reword according to the manual.
10948 Suggested by Olly Betts.
10950 2006-05-17 Olly Betts <olly@survex.com> (tiny change)
10951 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10953 * bin/autoreconf.in: Pass the directory argument to
10954 `require_configure_ac'. Fix comment.
10955 * tests/torture.at (Configuring subdirectories): Expose this.
10956 Reported by Olly Betts.
10958 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10960 * lib/Automake/Configure_ac.pm, lib/Automake/Channels.pm,
10961 lib/Automake/FileUtils.pm, lib/Automake/Struct.pm: Sync from
10962 Automake as follows:
10964 * lib/Autom4te/Configure_ac.pm (find_configure_ac): Use
10965 `$configure_in' instead of `configure.in', to preserve
10966 directory component.
10968 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10970 * config/config.guess, config/config.sub, config/texinfo.tex,
10971 doc/make-stds.texi, doc/standards.texi: Sync from upstream.
10973 2006-05-14 Paul Eggert <eggert@cs.ucla.edu>
10975 * lib/autoconf/headers.m4 (AC_HEADER_STDBOOL): Fix overly-picky
10976 test for C99 conformance; (bool) 0.5 is an integer constant
10977 expression, but (bool) -0.5 is not. Problem reported by Fedor
10978 Sergeev in <http://forum.sun.com/jive/thread.jspa?threadID=96202>.
10980 2006-05-13 Paul Eggert <eggert@cs.ucla.edu>
10982 * doc/autoconf.texi (Particular Programs): AC_PROG_MKDIR_P now
10983 sets MKDIR_P, not mkdir_p, to avoid collisions with Automake.
10984 Warn about obsolete install-sh files. Remove stray sentence
10985 fragment and fix cross reference.
10986 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Don't insist on
10987 install -d; this undoes the 2006-05-10 change.
10988 (MKDIR_P): Mark with AN_MAKEVAR.
10989 (AC_PROG_MKDIR_P): Fall back on $ac_install_sh, not $INSTALL, so
10990 that we don't require $INSTALL to be thread-safe. Move comments
10991 out of generated code. Require AC_CONFIG_AUX_DIR_DEFAULT instead
10992 of AC_PROG_INSTALL. Output a message saying that we're checking
10993 mkdir -p. Set MKDIR_P rather than mkdir_p. Do special magic for
10994 MKDIR_P instead of AC_SUBST.
10995 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE, _AC_OUTPUT_CONFIG_STATUS):
10996 Special magic for MKDIR_P, too.
10997 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Remove comment that defeated
10999 * tests/local.at (AT_CHECK_ENV): mkdir_p -> MKDIR_P.
11001 2006-05-11 Paul Eggert <eggert@cs.ucla.edu>
11003 Sync from Automake, as follows:
11005 2006-05-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11006 * config/install-sh: Initialize IFS, so field splitting isn't
11008 * config/mkinstalldirs: Likewise.
11009 * config/missing: Remove superfluous quotes. Replace all uses of
11010 `[' by `test', for consistency, and for..
11011 * config/missing (sed_minuso, sed_output): New variables.
11012 (autom4te, help2man, makeinfo): Use them. Unifies detection of
11013 `-o FILE', `--output FILE', `--output=FILE', stricter regex.
11014 Fixes `missing' to detect `--output' for help2man. Fixes
11015 PR automake/483. Report by Dennis J. Linse.
11016 (autom4te): Document in `missing --help'.
11018 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
11020 * NEWS: New macro AC_PROG_MKDIR_P. AS_MKDIR_P is now more robust.
11021 * config/install-sh: Don't use 'path' to talk about file names,
11022 as per GNU coding standards. Close a race condition reported by Ralf
11023 Wildenhues and Stepan Kasal. There is still a race condition
11024 on hosts that predate Posix 1003.1-1992, but we can't help this.
11025 Don't mishandle weird characters like space on pre-Posix hosts.
11026 Invoke mkdir at most once per dir arg on pre-Posix hosts.
11027 * doc/autoconf.texi (Programming in M4sh): Cross-reference to
11028 AC_PROG_MKDIR_P from AS_MKDIR_P.
11029 (Limitations of Usual Tools): Cross-reference to AC_PROG_MKDIR_P
11030 from mkdir. Mention that Autoconf 2.60 install-sh is safe but
11031 earlier editions are not (including Automake 1.8.3).
11032 Do not suggest mkinstalldirs for thread-safety.
11033 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Insist on an 'install'
11034 that understands -d, so that AC_PROG_MKDIR_P can fall back on $INSTALL.
11035 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Make it more robust in the
11036 presence of special characters and race conditions.
11037 * tests/local.at (AT_CHECK_ENV): Add mkdir_p to the list of variables
11038 in Autoconf's name space.
11040 2006-05-10 Bruno Haible <bruno@clisp.org>
11041 and Paul Eggert <eggert@cs.ucla.edu>
11043 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): New macro, taken
11044 from Automake with minor changes.
11045 * doc/autoconf.texi (Particular Programs): Document AC_PROG_MKDIR_P.
11047 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
11049 * config/install-sh: Update to Automake CVS version, as follows:
11050 2006-04-25 Stepan Kasal <kasal@ucw.cz>
11051 * lib/install-sh: Simplify the expr implementation of dirname.
11052 2006-04-24 Paul Eggert <eggert@cs.ucla.edu>
11053 * lib/install-sh: Handle --, and diagnose unknown options.
11055 2006-05-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11057 * tests/Makefile.am (AUTOTEST): Use `$(MY_AUTOM4TE)' instead of
11058 `./autom4te' to create `./testsuite', since the `all' target
11059 will ensure its presence, but `installcheck' should not create
11060 the uninstalled wrappers.
11062 * tests/torture.at (Unusual Automake input files): Skip if we
11063 detect automake < 1.8.
11065 2006-05-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11067 * lib/autoconf/c.m4 (AC_PROG_CC_STDC): If ac_cv_prog_cc_stdc
11068 is set to `no', then that overrides and sets ac_cv_prog_cc_c89
11069 and ac_cv_prog_cc_c99 to `no', for backward compatibility.
11072 2006-05-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11074 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Take care not to
11075 munge (multiple) white space and other oddities.
11076 * tests/torture.at (AT_CHECK_AC_ARG_VAR): Make sure to M4-escape
11077 single quotes in variable assignment.
11078 (AC_ARG_VAR, configure invocation): Adjust tests to expose this
11079 and similar failures by adding multiple spaces, tabs, and other
11080 special characters.
11081 Report and different test suggested by Francesco Romani
11082 <fromani@gmail.com> and Andrew Church <achurch@achurch.org>.
11084 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): When we escape
11085 single quotes, we only need to search for single quotes; this
11086 both simplifies the search pattern, and makes us less
11087 susceptible to `echo' variations for arguments not containing
11089 (_AC_ARG_VAR_VALIDATE): Likewise.
11091 2006-05-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11093 * doc/autoconf.texi (Special Shell Variables) <IFS>: Document
11094 `$*' and IFS concatenation issue with traditional shells and
11095 bash-2.04. Report by Seanster@Seanster.com.
11097 2006-05-03 Bruno Haible <bruno@clisp.org>
11099 * doc/autoconf.texi (Limitations of Usual Tools): Identify more
11100 precisely which Mac OS X versions have the od problem.
11102 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
11104 * doc/autoconf.texi: Use @option systematically.
11106 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
11107 and Bruno Haible <bruno@clisp.org>
11109 * doc/autoconf.texi (Limitations of Usual Tools): Add a paragraph
11111 (Integer Overflow): Mention the special case of integer division
11114 2006-05-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11116 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Cater for
11117 traditional shells like the Solaris one that do not use the
11118 first IFS character for assembling `$*'.
11119 Prompted by a related report from autoconf_bug@nro.ca.
11121 2006-05-01 Paul Eggert <eggert@cs.ucla.edu>
11122 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11124 * doc/autoconf.texi (Limitations of Builtins, Limitations of Make):
11125 Mention more problems with the -e option.
11127 2006-04-30 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11130 * doc/autoconf.texi (Systemology): Mention the Heirloom Project.
11132 * doc/autoconf.texi (Introduction, Pointers): Use `@/' liberally
11133 in URLs to improve DVI formatted output (requires texinfo 4.6).
11134 (System Services, Systemology, Shellology): Likewise.
11135 (Limitations of Usual Tools): Rewrite Mac OS X example for nicer
11138 * doc/autoconf.texi (Fortran Compiler): Do not use `@ovar' in
11140 (Runtime): Fix macro argument names to match description:
11141 `action-if-found' -> `action-if-true' and similarly.
11142 (Obsolete Macros): Likewise.
11143 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE): Likewise.
11144 (AC_COMPILE_IFELSE, AC_TRY_COMPILE, _AC_LINK_IFELSE)
11145 (AC_LINK_IFELSE, AC_TRY_LINK, AC_COMPILE_CHECK): Likewise.
11147 2006-04-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11149 * doc/autoconf.texi (Limitations of Make): Clean up markup.
11152 * doc/autoconf.texi (Portable Shell): Allow wrapped URLs, for
11155 2006-04-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

11159 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): Adjust.
11160 * tests/local.at: Likewise.
11162 2006-04-26 Paul Eggert <eggert@cs.ucla.edu>
11164 * doc/autoconf.texi (Portable C and C++, Varieties of Unportability):
11165 (Integer Overflow, Null Pointers, Buffer Overruns):
11166 (Floating Point Portability, Exiting Portably): New sections.
11167 (Writing Test Programs): Fix some langauge. Recommend exiting
11168 with status 1, not merely nonzero. Clarify exit declaration.
11169 (Run Time): Move C exit status stuff to new Exiting Portably section.
11170 (Systemology): Mention Posix and levenez. Update v7 reference.
11171 (Portable Shell): Mention the Posix shell.
11173 2006-04-25 Stepan Kasal <kasal@ucw.cz>
11175 * bin/autoconf.as (me): Replace by as_me.
11177 2006-04-25 Paul Eggert <eggert@cs.ucla.edu>
11179 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Don't use AS_ERROR,
11180 since as_me isn't set yet.
11182 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
11184 Prepare for deprecation of AS_BASENAME and AS_DIRNAME, and fix
11185 a few minor bugs in this area.
11187 * doc/autoconf.texi (Programming in M4sh): Comment out the
11188 documentation of AS_BASENAME, for now.
11189 (Shell Substitutions): Do not use AS_DIRNAME in an example.
11190 (Limitations of Builtins) <basename>: Do not refer to
11192 * bin/autoconf.as (me): Don't use AS_BASENAME.
11193 (dir): Remove the unused variable.
11194 * lib/m4sugar/m4sh.m4 (_AS_DETECT_REQUIRED): Renamed from
11195 AS_DETECT_REQUIRED. All uses changed.
11196 (_AS_DETECT_SUGGESTED): Renamed from AS_DETECT_SUGGESTED.
11198 (_AS_DETECT_BETTER_SHELL): Put ;; at the end of a case.
11199 (AS_BASENAME): Use "basename --" to protect against leading "-".
11200 (_AS_BASENAME_EXPR): Renamed from AS_BASENAME_EXPR. All uses changed.
11201 (_AS_BASENAME_SED): Renamed from AS_BASENAME_SED. All uses changed.
11202 (_AS_BASENAME_PREPARE): Reject implementations that cannot handle "--".
11203 (_AS_DIRNAME_PREPARE): Likewise.
11204 (_AS_DIRNAME_EXPR): Renamed from AS_DIRNAME_EXPR. All uses changed.
11205 (_AS_DIRNAME_SED): Renamed from AS_DIRNAME_SED. All uses changed.
11206 (AS_DIRNAME): Use "dirname --".
11208 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
11210 * doc/autoconf.texi (Runtime): Renamed from "Run Time". All uses
11211 of "run time" and "run-time" changed to "runtime", for consistency.
11212 * lib/autoconf/fortran.m4: Likewise (in comment).
11213 * lib/autoconf/functions.m4: Likewise.
11214 * lib/autoconf/general.m4: Likewise.
11215 * lib/autoconf/headers.m4: Likewise.
11217 * doc/autoconf.texi (Run Time): Document the exit status situation
11218 with more accuracy and detail.
11220 2006-04-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11222 * doc/autoconf.texi (Introduction): The GNU Autoconf Macro
11223 Archive is not officially `GNU' any more. Update URL.
11224 (Defining Directories): Likewise
11225 * lib/autoconf/c.m4 (AC_C_RESTRICT): Update URL.
11227 2006-04-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11229 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Remove the leading
11230 newline from the `trap' code to finish `config.log'; the NetBSD
11231 /bin/sh resets the exit status after an empty command, as
11232 documented in doc/autoconf.texi.
11233 Reported by Dalibor Topic <robilad@kaffe.org>.
11235 2006-04-19 Paul Eggert <eggert@cs.ucla.edu>
11237 * doc/autoconf.texi (C Compiler): Clarify AC_C_TYPEOF.
11238 Suggested by Bruno Haible.
11240 2006-04-18 Paul Eggert <eggert@cs.ucla.edu>
11242 * configure.ac (ac_cv_sh_n_works): Don't try to test for it, since
11243 some shells (e.g., Solaris 8 /bin/sh) implement it verrrry slowly.
11244 Instead, just list the shells that we know work.
11245 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Remove 2nd arg. All uses
11246 changed. Be more cautious about the _cv_ variable.
11247 * tests/tools.at (Syntax of the shell scripts): Check the
11248 _cv_ variable once, at first, to avoid an internal autoconf error
11249 when sh -n does not work.
11251 2006-04-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11253 * lib/Autom4te/FileUtils.pm: Sync from Automake.
11255 2006-04-16 Paul Eggert <eggert@cs.ucla.edu>
11257 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Don't
11258 use ">&-" since we're only 99.999% sure that this is portable,
11259 and since the MinGW bug is fixed in a different way.
11260 * lib/autotest/general.m4 (AT_INIT): Likewise.
11262 2006-04-16 Stepan Kasal <kasal@ucw.cz>
11264 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Handle --recheck
11265 before opening config.log, to avoid hitting a bug on MinGW.
11267 2006-04-14 Paul Eggert <eggert@cs.ucla.edu>
11269 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Close
11270 AS_MESSAGE_LOG_FD before reopening it onto the log file.
11271 This works around a MinGW bug reported by Eric Paire.
11272 Make sure that all writes to the log file append to it,
11273 rather than possibly losing data.
11274 * lib/autotest/general.m4 (AT_INIT): Likewise.
11276 2006-04-14 Stepan Kasal <kasal@ucw.cz>
11278 * lib/Autom4te/FileUtils.pm (find_file): Fix a typo in the
11281 2006-04-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11285 * configure.ac (AC_INIT): Bump to 2.59d.
11287 2006-04-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11291 * Makefile.maint (news-date-check): Do not require a leading `*'
11292 before the release date in NEWS.
11294 2006-04-12 Stepan Kasal <kasal@ucw.cz>
11295 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11297 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If the templates for
11298 the instantiated file do not contain the string 'datarootdir'
11299 but contain @datadir@, @docdir@, @infodir@, @localedir@, or
11300 @mandir@, replace the reference '${datarootdir}' by the value.
11301 * tests/torture.at (datarootdir workaround): New test.
11302 * NEWS: Advertise this temporary fixup.
11303 Based on a patch by Bruno Haible, reported and analyzed by
11304 Paul Eggert and Noah Misch.
11306 2006-04-12 Eric Blake <ebb9@byu.net>
11308 * tests/autotest.at (Debugging a failed test): Fix comment.
11310 2006-04-12 Stepan Kasal <kasal@ucw.cz>
11312 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): Simplify the summary of
11313 all the changes since 2006-04-07.
11315 2006-04-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11317 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): If `ln -s file1 file2'
11318 succeeded, but `ln -s file dir' failed, take care to remove the
11319 leftover target before the next test, to prevent its spurious
11320 failure; also make sure `ln file dir' works before selecting it.
11321 Thanks to Keith Marshall for pointing this out.
11324 * lib/autotest/general.m4 (AT_INIT): Store quoted variable
11325 assignments in `at_debug_args', so that we put them correctly
11326 in the `run' script.
11327 * tests/autotest.at (Debugging a failed test): Unmark XFAIL.
11328 Reported by Eric Blake.
11330 2006-04-11 Eric Blake <ebb9@byu.net>
11332 * tests/autotest.at (AT_CHECK_AT): Add new argument, to allow
11333 top-level tests after micro-suite has been run. Used in...
11334 (Debugging a successful test, Debugging script and environment),
11335 (Debugging a failed test): ...these new tests. The first of these
11337 * lib/autotest/general.m4 (_AT_CREATE_DEBUGGING_SCRIPT): New
11338 macro, split out from...
11339 (AT_INIT): ...here, so that using -d also generates a run script.
11340 Document that -d inhibits top-level logging.
11341 * doc/autoconf.texi (testsuite Invocation): Document that -d only
11342 inhibits top-level logging; debug scripts are created.
11344 * lib/autotest/general.m4 (_AT_CHECK): Avoid syntax error on empty
11346 * tests/autotest.at (Empty test, Empty check): New test to check it.
11348 * lib/autoconf/c.m4 (AC_C_CONST, AC_C_VOLATILE): Avoid warnings
11351 2006-04-10 Stepan Kasal <kasal@ucw.cz>
11353 * tests/mktests.sh: Use "trap '' 0", not "trap 0". Do not touch
11354 the files if a problem appears. Make the empty *.at files
11355 read-only, too. Proposed by Ralf Wildenhues.
11357 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11359 * config/Makefile.am: Add comment to force updated Makefile.in.
11361 * lib/freeze.mk: Fix typo in comment. Unlike the last, white
11362 space only patch to this file, this patch causes the Makefile.in
11363 files that include freeze.mk to be updated, and thus have a
11364 newer time stamp again, which in turn makes a pristine CVS
11365 checkout have correct time stamps.
11367 * Makefile.maint (cvs-sv): New macro, to be used..
11368 (config.guess-url_prefix, config.sub-url_prefix)
11369 (texinfo.tex-url_prefix, standards.texi-url_prefix): ..here;
11370 point to CVS text checkout of Gnulib files.
11371 (copyright-check): Bump current year.
11372 (announcement): Do not hard-wire `./announce-gen'.
11373 (cvs-update): Propagate failures of `cvs' and `move-if-change'
11375 * Makefile.cfg (executable-update): Use `chmod a+x' instead of
11377 (wget_files): Update config.guess, config.sub, texinfo.tex by
11378 `wget-update', now that their URLs work again.
11380 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
11382 * doc/autoconf.texi (Particular Types): Don't use AC_CHECK_TYPE.
11383 Problem noted by Paul D. Smith.
11385 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11387 * doc/autoconf.texi: Remove unused words from word list.
11388 * .x-sc_prohibit_atoi_atof, .x-sc_space_tab, .x-sc_sun_os_names,
11389 .x-sc_trailing_space: New files.
11391 * doc/standards.texi: Sync from gnulib.
11393 * NEWS, doc/autoconf.texi (AC_LIBOBJ vs LIBOBJS): Mark
11394 `LIBOBJDIR' as experimental.
11396 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): MSYS `ln -s' fails
11397 with a target directory; it's internally implemented as `cp'
11398 anyway, but since Autoconf advertises the possibility to use
11399 a target directory when LN_S is `ln -s', we need to find out.
11400 Reported by Rolf Ebert <rolf.ebert.gcc@gmx.de> against MSYS,
11401 analyzed by Keith Marshall <keith.marshall@total.com>.
11405 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
11407 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Just output
11408 confdefs.h as-is. In general, if it has backslash-newline or the
11409 like, then it doesn't work either to sort or to remove empty
11412 2006-04-09 Stepan Kasal <kasal@ucw.cz>
11414 * tests/Makefile.am (AUTOCONF_FILES): Fix typo in the comment.
11416 2006-04-09 Alexandre Duret-Lutz <adl@gnu.org>
11418 * lib/autom4te.in (Automake-preselections): Preselect
11421 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>
11423 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Use '\'' for an
11424 apostrophe within a single-quoted string, as this is the usual
11425 tradition and is easier to read than '"'"'. Don't rely on the
11426 shell treating "$/" like '$/'. Use a more-consistent indenting
11427 style for the trap.
11429 2006-04-09 Eric Blake <ebb9@byu.net>
11431 * tests/autotest.at (Backquote command substitution),
11432 (Multiline backquote command substitution): Remove mistaken
11433 AT_NO_CMDSUBST from the 2006-03-14 patch, which was meant to be
11435 (Parenthetical command substitution, Multiline parenthetical
11436 command substitution): here.
11438 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>
11440 Import macros from gnulib (often changing their name).
11442 * NEWS: AC_C_TYPE_LONG_DOUBLE is now obsolete.
11443 New macros AC_CHECK_DECLS_ONCE, AC_CHECK_FUNCS_ONCE,
11444 AC_CHECK_HEADERS_ONCE, AC_FUNC_STRTOLD, AC_HEADER_ASSERT,
11445 AC_STRUCT_DIRENT_D_INO, AC_STRUCT_DIRENT_D_TYPE,

11450 AC_TYPE_UINT64_T, AC_TYPE_UINTMAX_T, AC_TYPE_UINTPTR_T,
11451 AC_TYPE_UNSIGNED_LONG_LONG_INT, AC_USE_SYSTEM_EXTENSIONS.
11452 The manual mentions Gnulib more prominently.
11453 * doc/autoconf.texi (Gnulib): New node.
11454 (Pointers): Add Gnulib URL.
11455 (Particular Functions): Alphabetize. Add AC_FUNC_STRTOLD.
11456 (Generic Functions): Add AC_CHECK_FUNCS_ONCE. Refer to new
11458 (Particular Headers): Add AC_HEADER_ASSERT. For stdbool.h,
11459 suggest a #define rather than a typedef for _Bool, and mention
11460 Gnulib rather than trying to substitute stdbool code.
11461 (Generic Headers): Add AC_CHECK_HEADERS_ONCE.
11462 (Generic Declarations): Add AC_CHECK_DECLS_ONCE.
11463 (Particular Structures): Add AC_STRUCT_DIRENT_D_INO,
11464 AC_STRUCT_DIRENT_D_TYPE.
11465 (Particular Types): Mention stdint.h and inttypes.h as standard
11467 Add AC_TYPE_INT8_T, AC_TYPE_INT16_T, AC_TYPE_INT32_T, AC_TYPE_INT64_T,
11468 AC_TYPE_INTMAX_T, AC_TYPE_INTPTR_T, AC_TYPE_LONG_DOUBLE,
11469 AC_TYPE_LONG_DOUBLE_WIDER, AC_TYPE_LONG_LONG_INT, AC_TYPE_UINT8_T,
11470 AC_TYPE_UINT16_T, AC_TYPE_UINT32_T, AC_TYPE_UINT64_T,
11471 AC_TYPE_UINTMAX_T, AC_TYPE_UINTPTR_T, AC_TYPE_UNSIGNED_LONG_LONG_INT.
11472 (C Compiler): Move AC_C_LONG_DOUBLE to ...
11473 (Obsolete Macros): here. Under AC_LONG_DOUBLE, mention
11474 AC_TYPE_LONG_DOUBLE or AC_TYPE_LONG_DOUBLE_WIDER instead.
11475 (Posix Variants): Add AC_USE_SYSTEM_EXTENSIONS.
11476 (Coding Style). Don't mention m4_expand_once.
11477 * lib/autoconf/c.m4 (AC_C_LONG_DOUBLE): Implement via
11478 AC_TYPE_LONG_DOUBLE_WIDER. Now obsolete.
11479 * lib/autoconf/functions.m4 (_AH_CHECK_FUNCS): New macro.
11480 (AC_CHECK_FUNCS): Use it.
11481 (AC_CHECK_FUNCS_ONCE, AC_FUNC_STRTOLD): New macros.
11482 (AC_FUNC_WAIT3): "the Open Group standards" -> "POSIX".
11483 * lib/autoconf/general.m4 (AC_CHECK_DECLS_ONCE): New macro.
11484 * lib/autoconf/headers.m4 (AC_CHECK_HEADERS_ONCE): New macro.
11485 (AC_HEADER_ASSERT): New macro.
11486 (AC_HEADER_STDBOOL): Don't assume "#error" works.
11487 Catch a bug in IBM AIX xlc compiler version 6.0.0.0.
11488 Catch a bug in an HP-UX C compiler.
11489 * lib/autoconf/specific.m4 (AC_USE_SYSTEM_EXTENSIONS): New macro.
11490 * lib/autoconf/types.m4 (AC_TYPE_INTMAX_T. AC_TYPE_UINTMAX_T):

11494 (_AC_STRUCT_DIRENT, AC_STRUCT_DIRENT_D_INO, AC_STRUCT_DIRENT_D_TYPE):
11497 * tests/mktests.sh (ac_exclude_list, au_exclude_list): Do not
11498 use /^foo|bar$/, it does not mean /^(foo|bar)$/.
11500 2006-04-08 Stepan Kasal <kasal@ucw.cz>
11502 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Fix the wording
11503 of the warning introduced by the 2001-08-28 change.
11505 2006-04-08 Stepan Kasal <kasal@ucw.cz>,
11506 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11508 * lib/autoconf/general.m4 (AC_CACHE_SAVE): All `ac_cv_env_foo'
11509 variables shall be overriden by the cache.
11510 * tests/torture.at (AC_ARG_VAR): Test also with a first value
11511 that contains braces.
11513 2006-04-07 Stepan Kasal <kasal@ucw.cz>
11515 Revert the patch from 2006-04-01 and only improve
11516 _AS_DETECT_BETTER_SHELL:
11518 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Do not optimize; do not
11519 skip nonexistent directories.
11520 (_AS_DETECT_BETTER_SHELL): The optimization is moved here--try
11521 only shell candidates which exist.
11522 (AS_UNAME): No need to give three parameters to _AS_PATH_WALK.
11523 * lib/autotest/general.m4 (AT_INIT): No need to give three
11524 parameters to _AS_PATH_WALK.
11526 2006-04-07 Stepan Kasal <kasal@ucw.cz>,
11527 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11529 * bin/autoupdate.in (handle_autoconf_patches): Change the way we
11530 distinguish m4sugar macros.
11531 * tests/tools.at (autoupdating with aclocal and m4_include):
11532 New test. Bug reported by Gary V. Vaughan <gary@gnu.org>,
11533 test case by Noah Misch <noah@cs.caltech.edu>.
11535 2006-04-07 Stepan Kasal <kasal@ucw.cz>
11537 Revert my change from 2006-03-17, in other words:
11538 * lib/m4sugar/m4sh.m4 (AS_BOURNE_COMPATIBLE): Insert BIN_SH=xpg4
11540 (AS_SHELL_SANITIZE): Remove DUALCASE=1.
11541 * doc/autoconf.texi (Special Shell Variables) <BIN_SH>: Say that
11544 2006-04-07 Eric Blake <ebb9@byu.net>
11546 * doc/autoconf.texi (Programming in M4sh): Document that
11547 AS_MKDIR_P exits the script on failure.
11548 * lib/autotest/general.m4: Remove redundant AS_ERROR.
11550 2006-04-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11552 * config/elisp-comp, config/install-sh, config/mdate-sh,
11553 config/missing, config/mkinstalldirs: Sync from Automake.
11555 * lib/Autom4te/FileUtils.pm, lib/Autom4te/Struct.pm: Sync
11558 * doc/make-stds.texi: Sync from gnulib.
11560 2006-04-06 Eric Blake <ebb9@byu.net>
11562 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_O): Inside cache
11563 check, s/ac_exeext/ac_cv_exeext/. Fixes regression introduced
11566 2006-04-06 Stepan Kasal <kasal@ucw.cz>,
11567 Eric Blake <ebb9@byu.net>,
11568 Paul Eggert <eggert@cs.ucla.edu>,
11569 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11571 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): Fix the detection of
11572 whether `set' quotes correctly: redirect stderr of the tested
11573 `set', and use a subshell, for Ultrix; use `sed' instead of
11574 `grep' for zsh `set' which may write binary output; match only
11575 at the beginning of a line, to avoid false positives.
11576 In order to avoid false positives by unrelated variables with
11577 multiline content, put the dump algorithm in a subshell and
11578 unset all variables containing newlines (except some which are
11579 special to the shell). Warn about cache variables that are
11582 2006-04-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11584 * config/config.guess, config/config.sub, config/texinfo.tex:
11585 Sync from upstream.
11587 * tests/mktests.sh: Reword comments.
11589 * tests/mktests.sh: Only skip internal macros starting with
11590 `_AC_' or `__AC_'. Noted by Stepan Kasal.
11591 Update exclusion lists for the test suite to this end:
11592 (AC_ARG_VAR): Do test this now.
11593 (AC_SEARCH_LIBS, AC_REPLACE_FUNCS): Need an argument.
11594 (AC_LINKER_OPTION): Remove (renamed to _AC_LINKER_OPTION).
11595 (AC_LIST_MEMBER_OF): Likewise (renamed to _AC_LIST_MEMBER_IF).
11596 (AC_LINK_FILES): Obsoleted since (and thus AU_DEFUN'ed).

11793 (_AC_COMPILER_EXEEXT_O): Don't export ac_cv_exeext, it's not needed (or
11794 no longer needed) by libtool. Make it a cache check.

12504 * lib/autoconf/status.m4 (_AC_OUTPUT_MAIN_LOOP): Initialize
12505 `tmp' to avoid file removal race.
12507 2005-11-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
12509 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Initialize
12510 ac_clean_files and LIBOBJS.
12512 2005-11-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
12514 * lib/autoconf/programs.m4 (AC_CHECK_PROG, AC_PATH_PROG):
12515 Factor functionality to..
12516 (_AC_CHECK_PROG, _AC_PATH_PROG): these new macros, but only
12517 `AC_SUBST($1)' in the public version.
12518 (AC_CHECK_TOOL, AC_PATH_TOOL, AC_PATH_TARGET_TOOL)
12519 (AC_CHECK_TARGET_TOOL): Use internal versions for ac_ct_* and
12522 2005-11-01 Stepan Kasal <kasal@ucw.cz>
12524 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Remove the comment about 8+3
12527 2005-11-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
12529 * NEWS: Move AH_HEADER mention to right place.
12531 2005-10-27 Stepan Kasal <kasal@ucw.cz>
12533 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): "conftst2" -> "conftest2"
12534 * lib/autoconf/fortran.m4 (_AC_PROG_FC_C_O): Likewise.
12536 2005-10-25 Stepan Kasal <kasal@ucw.cz>
12538 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): rm -f conftst2.*, not only
12539 conftst2.$ac_objext.
12540 * lib/autoconf/fortran.m4 (_AC_PROG_FC_C_O): Likewise.
12542 2005-10-24 Stepan Kasal <kasal@ucw.cz>
12544 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Use conftst2.o instead of
12545 conftest.o, to see whether the compiler really obeys; rm the object
12546 file before and after the test and register it with ac_clean_files.
12547 * lib/autoconf/fortran.m4 (_AC_PROG_FC_C_O): Likewise.
12549 2005-10-21 Stepan Kasal <kasal@ucw.cz>
12551 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): When determining,
12552 the delimiter CEOF$ac_eof: fix quoting of CEOF[0-9]* and modify the
12553 code so that the most common case requires less forks.
12555 2005-10-20 Stepan Kasal <kasal@ucw.cz>
12557 * doc/autoconf.texi (Shell Substitutions}: Document that ${10} is
12558 not portable; thanks to Paul Eggert and Alexandre.
12560 * NEWS: Fix an old typo.
12562 2005-10-20 Jim Meyering <jim@meyering.net>
12564 * doc/autoconf.texi: Typo: s/feature/features/ in ``the features of
12565 the latter'', in two places.
12567 2005-10-19 Paul Eggert <eggert@cs.ucla.edu>
12569 * doc/autoconf.texi (Generating Sources): AC_LANG_PROGRAMS ->
12570 AC_LANG_PROGRAM, fixing a typo. Don't give details about
12571 the inner workings of AC_LANG_FUNC_LINK_TRY.
12572 * lib/autoconf/c.m4 (AC_LANG_CALL(C)): Reformat to match
12573 AC_LANG_FUNC_LINK_TRY. This involves returning the value returned
12574 by the function rather than ignoring it.
12575 (AC_LANG_FUNC_LINK_TRY(C)): Call the function rather than simply
12576 comparing its address. Intel's interprocedural optimization was
12577 outsmarting the old heuristic. Problem reported by
12580 2005-10-19 Stepan Kasal <kasal@ucw.cz>
12582 * lib/autoconf/general.m4 (AC_SUBST): Remove an obsolete comment.

12589 2005-10-04 Stepan Kasal <kasal@ucw.cz>
12591 * lib/autotest/general.m4 (AT_INIT): Really make the subtree writable
12592 before removing it (chmod -R u+rwx); there are three instances of this.
12594 2005-10-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
12595 Stepan Kasal <kasal@ucw.cz>
12597 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Balance parentheses.
12598 * lib/autotest/general.m4 (AT_INIT): If the test dir already exists,
12599 make its content writable before removing it. Remove an errorneous
12600 comment from the end, where the logs of the failed tests are copied
12601 to the main log file.
12603 2005-09-27 Stepan Kasal <kasal@ucw.cz>
12605 * tests/semantics.at (AC_C_BIGENDIAN): Pass --force to autoheader,
12606 in case the computer is too quick. Double quote the configure.ac
12609 * tests/local.at (AT_CHECK_AUTOCONF): Always pass --force to prevent
12610 problems if the testsuite were running too fast.
12612 2005-09-18 Paul Eggert <eggert@cs.ucla.edu>
12614 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Look for X11/Xlib.h
12615 and XrmInitialize rather than X11/Intrinsic.h and XtMalloc
12616 (which belong to Xt, not X itself). See Debian bug 327655.
12617 * NEWS: Mention this.
12619 2005-09-07 Stepan Kasal <kasal@ucw.cz>
12621 * lib/autoconf/c.m4 (AC_LANG_SOURCE(C)): Remove an incorrect comment.
12623 2005-09-06 Paul Eggert <eggert@cs.ucla.edu>
12625 * config/move-if-change: Don't output "$2 is unchanged";
12626 suggested by Ben Elliston. Handle weird characters correctly.
12628 2005-09-06 Stepan Kasal <kasal@ucw.cz>
12630 * lib/autoconf/libs.m4 (AC_SEARCH_LIBS): Merge the two AC_LINK_IFELSE
12631 calls, so that the final expansion of this macro is shorter.
12632 Create the conftest.$ac_ext outside the `for' loop, to speed the run.
12633 Do not use `break' in the argument to AC_LINK_IFELSE, it would skip
12634 the cleanup there. Use AS_VAR_* macros, to be more general.
12635 * tests/semantics.at (AC_SEARCH_LIBS): Check for the cleanup.
12637 * lib/autoconf/general.m4: Use AS_IF where appropriate.
12639 * lib/m4sugar/m4sh.m4 (AS_IF): Use m4_default.
12641 2005-09-01 Stepan Kasal <kasal@ucw.cz>
12643 * doc/autoconf.texi (Configuration Headers): Add an index entry
12646 2005-08-26 Pavel Roskin <proski@gnu.org>
12648 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): Use shell variable
12649 XMKMF to locate xmkmf. Make XMKMF precious. Export CC when
12652 2005-08-26 Paul Eggert <eggert@cs.ucla.edu>
12654 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE):
12655 The previous patch didn't work, so try a better one.
12657 2005-08-26 Stepan Kasal <kasal@ucw.cz>
12659 * doc/autoconf.texi (Programming in M4sh) <AS_TR_CPP>: Fix m4 quoting
12660 in the example. Reported by Bruno Haible.
12661 <AS_TR_SH>: Likewise. Also modify the example to be more convincing:
12662 "if $undefined_var;" succeeds with my shell.
12664 * lib/autoconf/general.m4 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST,
12665 AC_CANONICAL_TARGET): Define by AC_DEFUN, no need to use AC_DEFUN_ONCE;
12666 but change the m4_divert_text to m4_divert_once.
12668 2005-08-25 Paul Eggert <eggert@cs.ucla.edu>
12670 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE):
12671 Work around bug in Solaris /usr/xpg4/bin/awk.
12672 The bug is present in at least Solaris 8 through 10.
12674 2005-08-24 Stepan Kasal <kasal@ucw.cz>
12676 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Simplify; rejecting
12677 some evil values and relying on the fact that $* concatenates the
12678 parameters by the first character from IFS.
12680 2005-08-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
12681 Stepan Kasal <kasal@ucw.cz>
12683 * lib/autoconf/status.m4 (_AC_CONFIG_REGISTER_DEST): When the
12684 first header appears, define AH_HEADER.
12685 * doc/autoconf.texi (Configuration Headers): Document AH_HEADER.
12686 Update limitations about when to call AC_CONFIG_HEADERS.
12687 (Configuration Commands): Document that AC_CONFIG_COMMANDS_PRE
12688 parameter can call AC_SUBST, AC_DEFINE, or AC_CONFIG_FOOS; explain
12689 that AC_CONFIG_COMMANDS_PRE and AC_CONFIG_COMMANDS_POST are not
12690 ``Configuration Actions''; fix their index entries.
12692 * lib/autotest/general.m4 (AT_INIT): Process multiple keywords
12693 options correctly. Process N-M as M-N if M is smaller than N.
12694 Process ranges correctly so that N-N will run only N.
12695 Sort and uniquify the tests that will be run. If there is more
12696 than one test, reinsert the banners for the tests.
12697 * tests/autotest.at (Keywords): Unmark XFAIL.
12699 2005-08-23 Stepan Kasal <kasal@ucw.cz>
12701 * lib/autoconf/general.m4 (_AC_DEFINE_Q): Strip the parameter list
12702 before passing the macro name to AH_TEMPLATE.
12704 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): config.status
12705 now opens log after option processing; in particular, --version
12706 and --help do not touch config.log.
12708 * Makefile.maint: Revert the change from 2005-08-12.
12710 2005-08-22 Stepan Kasal <kasal@ucw.cz>
12712 * lib/autoconf/general.m4 (AC_ARG_ENABLE, AC_ARG_WITH): Factor out
12714 (_AC_ENABLE_IF, _AC_ENABLE_IF_ACTION): ... these new macros.
12716 2005-08-21 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
12718 * doc/autoconf.texi (Using Autotest, testsuite Scripts)
12719 (Autotest Logs, Writing testsuite.at, testsuite Invocation):
12722 * doc/autoconf.texi (Defining Symbols, Changed Results):
12723 Prepend to LIBS, not append, in examples.
12725 2005-08-16 Stepan Kasal <kasal@ucw.cz>
12727 When building in place, set srcdir="."; suggested by Tim Van Holder.
12729 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Do this; to recognize
12730 build in place, we need ac_pwd, and thus have to AC_REQUIRE ...
12731 (_AC_INIT_DIRCHECK): ... this macro and AC_DEFUN both of them.
12732 * lib/autoconf/status.m4 (_AC_SRCDIRS): Fix a comment: srcdir="."
12733 does not mean "no --srcdir option".
12735 2005-08-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
12737 * tests/autoscan.at (autoscan): New file.
12738 * tests/suite.at: Use it.
12739 * tests/Makefile.am (TESTSUITE_HAND_AT): Add it.
12740 Reported against Libtool by Gideon Go <gideon.go@gmail.com>.
12742 * tests/autotest.at (Keywords): Test keywords combinations.
12744 2005-08-12 Stepan Kasal <kasal@ucw.cz>
12746 * Makefile.maint (GZIP_ENV): When checking the help text of gzip,
12747 add "2>&1"; gzip 1.2.4 prints help on stderr.
12749 2005-07-27 Stepan Kasal <kasal@ucw.cz>
12751 * lib/autotest/general.m4 (_AT_DECIDE_TRACEABLE): The symbol at_reason
12752 was pushdef'ed twice while popped only once. Push it only once.
12753 (_AT_CHECK): Cosmetic changes to the "case $at_status" command.
12755 2005-07-26 Stepan Kasal <kasal@ucw.cz>
12757 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): The message is now
12758 prefixed by mere "===", not "configure: === ".
12760 2005-07-25 Paul Eggert <eggert@cs.ucla.edu>
12762 * Makefile.maint: Update from Bison.
12764 * lib/m4sugar/m4sugar.m4 (m4_strip): Comment fix---change tab to
12765 "<tab>" in comment, so that the point is understandable.
12767 2005-07-25 Stepan Kasal <kasal@ucw.cz>
12769 Rewrite substantial part of lib/autoconf/status.m4.
12770 The main change is that CONFIG_FILES, CONFIG_HEADERS, CONFIG_LINKS,
12771 and CONFIG_COMMANDS are not processed in four separate loops.
12772 Instead, there is one main loop. This alows that the common code
12773 is expanded only once, thus config.status (and configure) is smaller.
12775 The registration mechnism in AC_CONFIG_FILES and cousins also changed;
12776 the AC_LIST_FILES and cousins macros are no longer used.
12778 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES, _AC_OUTPUT_HEADERS,
12779 _AC_OUTPUT_LINKS, _AC_OUTPUT_COMMANDS): Renamed to ...
12780 (_AC_OUTPUT_FILE, _AC_OUTPUT_HEADER, _AC_OUTPUT_LINK,
12781 _AC_OUTPUT_COMMAND): ..., respectively. These macros no longer
12782 contain the initialization, nor the for loop, nor the associated
12783 commands; all these go to ...
12784 (_AC_OUTPUT_MAIN_LOOP): ... this new macro, called from
12785 _AC_OUTPUT_CONFIG_STATUS.
12786 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST, _AC_CONFIG_SPLIT_FILE_IN):
12787 Nuked; the code was merged into _AC_OUTPUT_MAIN_LOOP.
12788 (_AC_OUTPUT_FILE): The creation of the sed script ...
12789 (AC_OUTPUT): ... and the setup of ac_vpsub goes to ...
12790 (_AC_OUTPUT_FILES_PREPARE): ... a new macro, also called from
12791 _AC_OUTPUT_MAIN_LOOP.
12792 (_AC_CONFIG_FILES, _AC_CONFIG_HEADERS, _AC_CONFIG_LINKS,
12793 _AC_CONFIG_COMMANDS): Use ...
12794 (_AC_CONFIG_FOOS): ... this new macro, which uses these ...
12795 (_AC_CONFIG_REGISTER, _AC_CONFIG_REGISTER_DEST): ... new macros.
12796 (_AC_CONFIG_FILE, _AC_CONFIG_HEADER, _AC_CONFIG_LINK,
12797 _AC_CONFIG_COMMAND, _AC_CONFIG_DEPENDENCIES): No longer needed.
12798 (_AC_CONFIG_DEPENDENCY): Update, it uses these ...
12799 (_AC_CONFIG_DEPENDENCY_DEFAULT, _AC_FILE_DEPENDENCY_TRACE_COLON):
12801 (_AC_CONFIG_UNIQUE): Update.
12802 (AC_LIST_FILES, AC_LIST_HEADERS, AC_LIST_LINKS, AC_LIST_COMMANDS):
12803 Replaced by this ...
12804 (_AC_LIST_TAGS): ... new common macro.
12805 (AC_LIST_FILE_COMMANDS, AC_LIST_HEADER_COMMANDS, AC_LIST_LINK_COMMANDS,
12806 AC_LIST_COMMAND_COMMANDS): Replaced by this ...
12807 (_AC_LIST_TAG_COMMANDS): ... new common macro.
12808 (_AC_CONFIG_COMMANDS_INIT): Moved top to the `registration' section;
12809 this didn't belong to the `config commands' section.
12810 (_AC_OUTPUT_COMMANDS_INIT): Don't initialize, m4_ifdef is our friend.
12811 (AC_CONFIG_COMMANDS_PRE, AC_OUTPUT_COMMANDS_PRE,
12812 AC_CONFIG_COMMANDS_POST): Moved to a new section, these didn't belong
12813 to the `config commands' section either.
12814 (AC_CONFIG_SUBDIRS): Don't touch diversion DEFAULTS.
12815 (_AC_LIST_SUBDIRS): Don't initialize, m4_ifdef is our friend.
12817 ... and many changes to the comments nearby.
12819 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): At the end of the day,
12820 set ac_subdirs_all='_AC_LIST_SUBDIRS'.
12821 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
12822 AC_CONFIG_COMMANDS(command:input,...) is no longer allowed.
12823 (#define header templates): The comment at the top of the generated
12824 header now includes the name(s) of the source file(s).
12826 Several unrelated small changes:
12828 * lib/autoconf/general.m4 (AC_CACHE_VAL): Be didactic, quote the first
12829 parameter to AC_DIAGNOSE.
12830 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS): Likewise.
12831 (_AC_LINK_FILES_CNT): Don't AU_DEFUN this; it causes confusing messages
12832 with autoupdate; use m4_define_default inside AU_DEFUNed AC_LINK_FILES.
12833 (AC_OUTPUT): In the compatibility code, use m4_ifvaln, to be consistent
12834 with AU::AC_OUTPUT.
12835 (AU::AC_OUTPUT): Don't double-quote $2 and $3, the compatibility code
12836 in AC_OUTPUT doesn't double-quote it either.
12837 * tests/tools.at (autoupdate): AU::AC_OUTPUT no longer double-quotes the
12840 2005-07-10 Stepan Kasal <kasal@ucw.cz>
12842 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Document which
12843 versions of Portland Group compiler produce single- and double-quoted
12844 -cmdline argument. Reported by Steven G. Johnson <stevenj@fftw.org>
12845 and Ole Holm Nielsen <Ole.H.Nielsen@fysik.dtu.dk>.
12847 2005-07-07 Paul Eggert <eggert@cs.ucla.edu>
12849 * tests/local.at (AT_CONFIG_CMP): Ignore lines like "LIBS=''" too.
12850 This is a corrected version of yesterday's patch.
12852 2005-07-07 Stepan Kasal <kasal@ucw.cz>
12854 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Report the full
12855 path, too; insert a "===" to emphasize the line.
12857 * lib/autoconf/general.m4 (AC_CANONICAL_BUILD): Rename
12858 ac_cv_build_alias to ac_build_alias.
12859 (AC_CANONICAL_HOST, AC_CANONICAL_TARGET): Simplify.
12861 On 2005-02-24, an unintentional AC_SUBST([CC]) was introduced; this
12862 change eliminates it. Problem reported by Alexandre Duret-Lutz.
12863 * lib/autoconf/general.m4 (_AC_ARG_VAR_PRECIOUS): Move the AC_SUBST ...
12864 (AC_ARG_VAR): ... here.
12865 (_AC_INIT_PREPARE): Call AC_SUBST for build_alias, host_alias and
12868 Keep a list of all precious variables and process them with one simple
12869 for loop, instead of expanding all commands, or, OTOH, complicated
12870 processing of output of "set".
12871 * lib/autoconf/general.m4 (_AC_ARG_VAR_PRECIOUS): Acumulate the
12872 variable names in new macro...
12873 (_AC_PRECIOUS_VARS): ... which will be assigned to ac_precious_vars.
12874 (_AC_ARG_VAR_STORE): New macro which writes to diversion PARSE_ARGS
12875 a loop to assign all ac_env_* and ac_cv_env_* variables.
12876 (_AC_ARG_VAR_VALIDATE): Use shell variable ac_precious_vars, divert
12878 (_AC_INIT_DEFAULTS): At the end, if _AC_PRECIOUS_VARS is set, assign
12879 its value to shell variable ac_precious_vars and call
12880 _AC_ARG_VAR_STORE and _AC_ARG_VAR_VALIDATE.
12881 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Don't call
12882 _AC_ARG_VAR_VALIDATE.
12884 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Move AC_LANG_PUSH(C)
12885 and the AC_SUBSTs ...

12889 the ac_subst_files section in config.log.

12900 Fix problems reported by Nicolas Joly.
12901 * tests/base.at (Input/Output): Ignore 'loading site script' chatter.
12902 * tests/local.at (AT_CONFIG_CMP): Ignore lines like "LIBS=''" too.
12903 They are generated by the Tru64 v5.1B shell.
12905 2005-07-05 Stepan Kasal <kasal@ucw.cz>
12907 Fix my changes from 2005-07-01; reported by Noah Misch.
12908 * lib/autoconf/status.m4 (_AC_CONFIG_DEPENDENCIES): Fix the
12909 description, the macro now accepts only a single tag.
12910 (_AC_CONFIG_UNIQUE): Likewise; s/AC_File/[$1]/
12912 Fix cases when the varsions of Autoconf and Autotest don't match.
12913 Reported by Noah Misch.
12914 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Set also
12915 at_top_builddir, for compatibility with older autotest.
12916 * lib/autotest/general.m4 (AT_INIT): If at_top_build_prefix
12917 is not set, use at_top_builddir, for compatibility with older
12918 versions of autoconf.
12920 2005-07-04 Paul Eggert <eggert@cs.ucla.edu>
12922 * bin/autom4te.in ($m4): Catch usages like --nesting-limit=2048.
12923 Problem reported by Patrick Welche.
12925 2005-07-03 Paul Eggert <eggert@cs.ucla.edu>
12927 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Use &, not |, in
12928 sed substitution command, so that we allow | in program prefixes
12929 and program suffixes. (& is a problem anyway; we're not fixing
12931 * lib/autoconf/status.m4 (AC_CONFIG_FILES): Likewise, for
12932 configure_input, top_builddir, srcdir, etc.
12933 * lib/autotest/general.m4 (AT_INIT): Likewise, for
12934 PATH_SEPARATOR in AUTOTEST_PATH.
12936 2005-07-02 Alexandre Duret-Lutz <adl@gnu.org>
12938 * lib/autoconf/general.m4 (AC_SITE_LOAD): Rewrite the
12939 for loop over config.site files using `set', to allow
12940 directory names containing IFS characters.
12942 2005-07-01 Paul Eggert <eggert@cs.ucla.edu>
12944 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Remove the tests for
12945 directories with weird names. Apparently some people like living
12946 on the edge. However, improve the test that "pwd" actually does
12947 report a name for the working directory.
12948 * NEWS: Remove the claim that we test for funny chars in dir names.
12950 2005-07-01 Stepan Kasal <kasal@ucw.cz>

12966 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Use a here
12967 document to output the default config_* lists to config.status.
12968 Don't recognize option --file, if the functionality is not there.
12969 Likewise for --header; moreover, recognize --he and --h as shortcuts
12970 for --help in that case.
12972 * lib/autoconf/status.m4: Fix the order of the "sections", so that it
12973 matches the order of execution. No code changed.

12995 instead of AC_SUBST; proposed by Alexandre Duret-Lutz.
12996 (AC_SUBST): Call it.
12997 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Call AC_SUBST_TRACE for
12998 the directory specific variables; but don't call it for configure_input.
13000 2005-06-28 Derek Price <derek@ximbiot.com>
13002 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: Reword recent
13005 2005-06-23 Paul Eggert <eggert@cs.ucla.edu>
13007 * NEWS: Don't worry about spaces in bindir etc. Only srcdir and working
13008 directory have inherent problems with special characters like spaces,
13009 due to limitations in Make syntax. Problem reported by Alexandre
13011 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Implement the above.
13012 Also, fix Tru64 porting problem with shell patterns,

13024 from Justace Clutter.
13025 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Put name of invalid
13026 variable into diagnostic. Make the diagnostic an error, not a warning,
13027 because we really don't support spaces and suchlike in dir names.
13028 (_AC_INIT_SRCDIR): Allow special characters in $ac_unique_file.
13029 Don't worry about backslashes in srcdir; it can't happen now.

13040 (AT_CONFIG_CMP): Use sed instead of grep plumbing.
13042 * doc/autoconf.texi (Limitations of Usual Tools) <grep>: Mention
13043 that '\|' is not allowed in BREs; recommend using newline separated
13044 list of patterns instead of multiple -e options.
13046 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Remove an old comment.
13048 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Use AC_SUBST/2.

13054 2005-06-21 Stepan Kasal <kasal@ucw.cz>
13056 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: Document that
13057 b, t, r, w commands require single space, while : cannot have any.
13058 (Special Shell Variables): Fix sed code this in the example.
13059 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Likewise; and fix a typo.
13060 * lib/autotest/general.m4 (AT_ARG_OPTION): Fix typo in the description.
13062 * lib/m4sugar/m4sugar.m4 (m4_split): If the parameter is empty,
13063 expand to the empty list. Don't use two pairs of m4_changequote,
13064 it's not necessary.
13066 2005-06-20 Derek Price <derek@ximbiot.com>
13068 * lib/m4/programs.m4 (AC_PROG_YACC): Declare YACC & YFLAGS precious.
13070 2005-06-17 Paul Eggert <eggert@cs.ucla.edu>
13072 * lib/m4sugar/m4sh.m4 (as_awk_strverscmp): Port to Solaris /bin/awk.
13073 * doc/autoconf.texi:
13074 Don't mention Solaris versions so much, if a
13075 problem is common to all extant versions of Solaris. Say "SunOS
13076 4" instead of "SunOS" for SunOS 4.
13077 (awk): Mention more of the limitations of traditional Awk.
13078 (cat): Don't talk about cat -v.
13080 2005-06-16 Paul Eggert <eggert@cs.ucla.edu>
13082 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE): New macro.
13083 (AS_VERSION_COMPARE): New macro. The API is taken from CVS,

13085 to be compatible with glibc strverscmp.
13086 * tests/m4sh.at (AS_VERSION_COMPARE): New test.
13088 * doc/autoconf.texi (Limitations of Usual Tools): Mention expr bug

13091 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT):
13092 Use shell builtins rather than 'expr', to work around expr bug.
13094 2005-06-10 Paul Eggert <eggert@cs.ucla.edu>
13096 * doc/autoconf.texi: "filesystem" -> "file system".

13099 * lib/autoconf/general.m4: Omit blank after ":" sed command,
13101 * lib/m4sugar/m4sh.m4: Likewise.
13102 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Work around problem
13103 with Solaris sed. Fix by Ralf Menzel and Stepan Kasal.

13106 (.x.1): Ignore the time stamp in the .TH line when deciding whether
13107 to update the man page. That way, we don't have to check in new
13108 man pages every month.
13110 * lib/m4sugar/m4sh.m4 (AS_VAR_TEST_SET): Work even if $1 contains
13111 quotes and backslashes. Patch from Derek Price.

13120 * lib/autotest/general.m4 (AT_INIT): Don't accept Solaris 9's diff
13121 -u, since it outputs chatter if the input files are the same.
13122 Problem reported by Ralf Menzel.
13124 2005-06-08 Derek Price <derek@ximbiot.com>
13126 * lib/m4sugar/m4sugar.m4: Undefine include & sinclude rather than
13127 renaming them since they are about to be redefined anyhow.
13129 2005-06-08 Derek Price <derek@ximbiot.com>
13131 * doc/autoconf.texi (Redefined M4 Macros): Add index entries for most
13132 redefined M4 macros to this node. Document m4_include & m4_sinclude.
13133 Move m4_undefine to alphabetical order.
13135 2005-06-07 Paul Eggert <eggert@cs.ucla.edu>
13137 * README: Recommend GNU M4 1.4.3 or later.
13138 * doc/autoconf.texi (Introduction): Likewise.
13139 Reword to avoid some formatting glitches.
13140 Use "#!/bin/sh", not "#! /bin/sh"; the space isn't needed these days.
13141 Clarify explanation of HP compiler bug.
13142 Redo example output tp match current CVS snapshot.
13143 Use @example.org in email addresses when the examples
13144 might get inadvertently cut-and-pasted into user code.
13145 Remove example of autom4te usage that doesn't seem to work now.
13146 Use modern AC_INIT (except when the example is meant to be
13147 shown with Autoconf 2.13).
13148 Update ksh info for Solaris 9 and later.
13150 Modernize description of Automake versions a bit.
13151 Don't claim a future version of Autoconf is near.
13152 * doc/install.texi: Reword to avoid some formatting glitches.
13154 2005-06-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
13156 * doc/autoconf.texi: Add [] to examples, so that the manual
13157 follows its own advice about quoting better.
13158 Reword to avoid some formatting glitches.
13159 * doc/installt.exi: Reword to avoid some formatting glitches.
13161 * doc/autoconf.texi (Limitations of Builtins) <case>: Mention
13162 Tru64 ksh pattern matching bug. Reported against Libtool by
13163 Albert Chin <libtool@mlists.thewrittenword.com> and
13164 Nicolas Joly <njoly@pasteur.fr>.
13166 2005-06-06 Stepan Kasal <kasal@ucw.cz>
13168 m4_cdr of one-member list was [[]] (one-member list containing an
13169 empty string) instead of [] (an empty list. Callers were skewed to
13170 match this misbehaviour. As a consequence of this:
13171 - m4_foreach([x], [], [foo]) expanded to `foo', while
13172 - the expansion of m4_foreach([x], [[]], [foo]) was empty.
13173 This bug has been fixed:
13175 * lib/m4sugar/m4sugar.m4 (m4_cdr): If only one argument is given,
13176 expand to an empty string; print error msg if called without
13178 (m4_foreach, m4_map, m4_map_sep): Don't expect the previous
13179 misbehaviour; handle [] and [[]] correctly.
13181 2005-06-06 Stepan Kasal <kasal@ucw.cz>
13183 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Nuke ac_max_here_lines.
13184 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Simplify the sed
13185 scripts created and the loop applying them, use _AC_SED_CMD_LIMIT.
13187 2005-06-06 Ralf Menzel <menzel@ls6.cs.uni-dortmund.de> (trivial change)
13189 * doc/autoconf.texi (Limitations of Usual Tools): Solaris' awk cannot
13190 swallow records with more than 99 fields.
13191 * lib/autotest/general.m4 (AT_INIT): Use the awk builtin `split' to
13192 parse the long line.
13194 2005-06-04 Stepan Kasal <kasal@ucw.cz>
13196 * doc/autoconf.texi (Limitations of Usual Tools): AIX awk cannot
13197 swallow literals longer than 399. Reported by Ralf Wildenhues.
13198 * lib/autotest/general.m4 (AT_INIT): Pass $at_groups though stdin,
13199 to workaround this limitation.
13201 2005-06-03 Steven G. Johnson <stevenj@alum.mit.edu>
13203 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Find g95 in addition
13204 to gfortran, and make these the first two compiler names
13205 checked (following the general autoconf preference for gcc).
13207 2005-06-03 Stepan Kasal <kasal@ucw.cz>
13209 * tests/Makefile.am (check_SCRIPTS): Set to $(wrappers).
13210 (DISTCLEANFILES): Remove $(check_SCRIPTS).
13211 (testsuite): Make sure autotest.m4f is up-to-date before using it.
13213 2005-06-02 Paul Eggert <eggert@cs.ucla.edu>
13215 * lib/autotest/general.m4 (AT_INIT): Don't create a regular
13216 expression of unbounded size when processing the --list
13217 option. This runs afoul of a limit of 399 bytes per regular
13218 expression on AIX. Problem reported by Ralf Wildenhues.
13220 2005-06-01 Paul Eggert <eggert@cs.ucla.edu>

13223 * doc/autoconf.texi (Particular Headers): Reword example
13224 for multiline stdbool replacement.
13225 (Setting Output Variables): Reword text a bit. Don't
13226 give all the details about |#_!!_#|.
13227 Reword description of line replacement.
13229 2005-05-31 Dan Manthey <dan_manthey@partech.com>
13231 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Output variables may
13232 now contain newlines, and substituted files must be referenced on
13233 a line alone; the sed scripts to substitute them are now very
13235 (_AC_SED_CMD_LIMIT): Added; single place to store limit on how many
13236 commands can be put in a sed script portably.
13237 * doc/autoconf.texi (Setting Output Variables): Document above
13238 changes. (Particular Header Checks) <AC_HEADER_STDBOOL>: Give exaple
13239 use of multiline substitution.

13245 From Ralf Menzel (trivial change).
13247 2005-05-25 Paul Eggert <eggert@cs.ucla.edu>
13249 * tests/local.at: Don't attempt to check for negated character
13250 classes in shell scripts. The test was too brittle.
13252 2005-05-25 Stepan Kasal <kasal@ucw.cz>
13254 * bin/autoconf.as: Don't use "shift 2"; it's not portable enough.
13255 * doc/autoconf.texi (Limitations of Builtins): Document this
13258 2005-05-24 Stepan Kasal <kasal@ucw.cz>
13260 * lib/m4sugar/m4sh.m4 (_AS_ECHO_LOG): New macro to factor out
13261 common code; used in many places in the tree.

13265 * lib/m4sugar/m4sugar.m4 (m4_ifset): Use m4_ifval.
13267 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Merge the two error
13268 messages when ac_unique_file is not found.
13269 (AC_CONFIG_MACRO_DIR): Simplify the `if' at the end.
13270 (AC_MSG_CHECKING, AC_MSG_RESULT): Put braces around the two echo
13271 commands, for consistency with AC_MSG_ERROR and such.
13273 * bin/autoconf.as: Make more use of "shift 2" in option processing.

13283 2005-05-20 Stepan Kasal <kasal@ucw.cz>
13285 * NEWS: @top_builddir@ is now a dirname, ac_top_builddir will follow.
13286 * lib/autoconf/status.m4 (_AC_SRCDIRS): Rename ...
13287 (ac_top_builddir): ... this ...
13288 (ac_top_build_prefix): ... to this; the old name is also kept, for
13289 backward compatibility.
13290 (ac_top_builddir_sub): New variable, without the trailing slash,
13292 (_AC_OUTPUT_FILES): s/@top_builddir@/$ac_top_builddir_sub/
13293 * doc/autoconf.texi (Configuration Actions): Rename
13294 ac_top_builddir to ac_top_build_prefix.

13306 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Don't m4_quote the second
13307 argument to m4_foreach. I guess it was necessary in the past,
13308 but I think it's a no-op now.
13310 2005-05-17 Stepan Kasal <kasal@ucw.cz>
13312 * lib/autoconf/general.m4 (_AC_INIT_HELP): Merge two consecutive
13313 ``cat <<_ACEOF'' commands to one.
13314 (_AC_CANONICAL_SPLIT): Use expr, not ``echo|sed.''
13315 * lib/autoconf/status.m4: On various places, use expr instead of
13317 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST):
13318 (_AC_CONFIG_SPLIT_FILE_IN): New macros, to factor out common code.

13321 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Use awk to search for
13322 the wrong patterns between ``case'' and ``esac.'' The previous
13323 code had false positives.

13387 abbreviations of --version and --debug.
13389 2005-05-10 Paul Eggert <eggert@cs.ucla.edu>
13391 * doc/autoconf.texi (Autoconf Language): Be more precise about
13392 quoting rules. Problems noted by Stepan Kasal.
13393 Also, throughout this document, be more careful about white space.
13394 "blank", "white space", and "space" all have different meanings
13395 and we should be careful to say what we mean.
13397 2005-05-05 Paul Eggert <eggert@cs.ucla.edu>

13416 set by latest automake.
13418 2005-05-01 Paul Eggert <eggert@cs.ucla.edu>
13420 * doc/autoconf.texi (Limitations of Usual Tools): "expr '' \| ''"
13421 outputs 0 on GNU/Linux these days.
13423 2005-04-29 Paul Eggert <eggert@cs.ucla.edu>
13425 * doc/autoconf.texi (Autoconf Language): Add more description
13426 about quoting heuristics.
13427 (Limitations of Builtins): Describe "set -" problems.
13429 2005-04-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
13431 * lib/autotest/general.m4 (AT_KEYWORDS): Separate by space,
13434 * doc/autoconf.texi (External Software): Replace AC_DEFINE_UNQUOTED
13435 by AC_DEFINE; it was a mistake.
13436 From bug reported against libtool by Dalibor Topic <robilad@kaffe.org>.
13438 2005-04-25 Stepan Kasal <kasal@ucw.cz>
13440 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): A tiny optimization.
13442 2005-04-22 Stepan Kasal <kasal@ucw.cz>
13444 * doc/autoconf.texi (External Software): Quadrigraphs are not
13445 processed correctly in AS_HELP_STRING; avoid this in the examples.
13446 * lib/m4sugar/m4sh.m4 (AS_HELP_STRING): Add a FIXME about quadrigraphs.
13447 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Likewise; and rephrase the
13448 comment and reduce m4_default([foo], []) to [foo].
13449 (m4_strip): Update the explanation.
13451 2005-04-19 Paul Eggert <eggert@cs.ucla.edu>
13453 * lib/autoconf/general.m4 (_AC_INIT_PREPARE, _AC_RUN_IFELSE):
13454 Remove core.conftest.* too; it's generated by Tru64 5.1.
13455 Problem reported by Jennis Pruett.
13456 * lib/autoconf/functions.m4
13457 (AC_FUNC_SETVBUF_REVERSED, AC_FUNC_UTIME_NULL):
13458 Don't bother to remove core files; AC_RUN_IFELSE should do that

13463 * lib/m4sugar/m4sugar.m4 (m4_bpatsubsts): Add the b- to comment, too.

13480 2005-04-13 Paul Eggert <eggert@cs.ucla.edu>
13482 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Look for configure.ac

13485 2005-04-10 Paul Eggert <eggert@cs.ucla.edu>
13487 * doc/autoconf.texi (Particular Functions): Use gnulib's current

13500 * lib/autotest/general.m4 (AT_INIT): Don't assume that "date +%s"
13501 fails if %s isn't supported. Problem reported by Ralf Wildenhues.
13503 2005-03-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
13505 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS):
13506 Merge `-z option' as well for the benefit of Solaris link flags. Pass
13507 whole-archive (-zallextract, -zdefaultextract) options in the hope of
13508 unique libraries, for the Sun Fortran 95 8.0 compiler. Bug reported
13509 against Libtool by Yury Puhalsky <pooh@cryptopro.ru>.
13511 2005-03-22 Paul Eggert <eggert@cs.ucla.edu>
13513 * NEWS: The configure command now warns you if you attempt to use
13514 a directory whose name contains a special character like space,
13516 * doc/autoconf.texi (Installation Directory Variables): Allow
13517 "," in file names. Do not use \@; it's not a portable regexp.
13518 * bin/Makefile.am (edit): Likewise.
13519 * lib/Makefile.am (edit): Likewise.

13526 unportable file names.
13527 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): New macro.
13529 (_AC_INIT_SRCDIR): Use ac_pwd rather than invoking pwd.
13530 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Propagate
13531 ac_pwd, and quote srcdir.
13532 * lib/autotest/general.m4 (AT_INIT): Quote file name args.
13534 * doc/autoconf.texi: Fix some systematic formatting problems.
13535 ".)" needs a following @: if not at the end of a sentence, and
13536 similarly for "!)". "etc." should be preceded by a comma.
13537 "n-th" -> "@var{n}th". pdksh is still buggy, so update its date.
13539 2005-03-22 Bruno Haible <bruno@clisp.org>
13541 * doc/autoconf.texi (Input): Mention that AC_CONFIG_AUX_DIR's
13542 argument is often called 'build-aux'.
13544 2005-03-07 Stepan Kasal <kasal@ucw.cz>
13546 * doc/autoconf.texi (Quotation Rule Of Thumb): Mention that the
13547 macro AC_TRY_LINK is obsolete.
13548 (Installation Directory Variables): Change `AC_OUTPUT_FILES' to
13551 2005-02-24 Stepan Kasal <kasal@ucw.cz>
13553 * lib/autoconf/c.m4 (AC_PROG_CC): Be more careful to skip
13554 `/usr/ucb/cc'; use `cl.exe' to distinguish the MS compiler
13555 from a Common Lisp's `cl'.
13556 (AC_PROG_CXX): Behave according to the documentation: don't
13557 search for $ac_tool_prefix$CCC and $CCC, just set CXX=$CCC;
13558 make the variable CCC precious; use `cl.exe', not `cl'.
13560 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
13561 Alexandre Duret-Lutz <adl@gnu.org>
13563 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin from
13564 /dev/null, as "configure" shouldn't read stdin, and this insulates
13565 us from problems (e.g., when testing for "cl"). Also, do this
13566 redirection before invoking "hostname" or "uname", and keep the
13567 original input stream available via...
13568 (AS_ORIGINAL_STDIN_FD): ... this new macro.
13569 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't
13570 bother with "</dev/null" since it's now done at the top of

13579 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
13581 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N_PREPARE): Don't set ECHO_C to
13582 newline if neither \c nor -n work, as that would output two
13583 newlines. Prefer -n to \c. Reported by Stepan Kasal.
13585 2005-02-12 Stepan Kasal <kasal@ucw.cz>
13587 * lib/m4sugar/m4sh.m4 (AS_IF): Define by m4_defun, not m4_define.
13588 This causes that any required macros inside will get before the if.
13589 * doc/autoconf.texi (autom4te.cache): A typo.
13591 2005-02-12 Paul Eggert <eggert@cs.ucla.edu>
13593 Undo previous change, except keep the change to
13594 lib/autoconf/programs.m4 that replaced grep with shell
13595 pattern-matching. This is because net-snmp configure reads stdin.
13596 Reported by Noah Misch.
13598 2005-02-11 Paul Eggert <eggert@cs.ucla.edu>
13600 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin
13601 from /dev/null, as "configure" shouldn't read stdin, and this
13602 insulates us from problems (e.g., when testing for "cl").
13603 Suggested by Alexandre Duret-Lutz. Also, do this redirection
13604 before invoking "hostname" or "uname".
13605 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
13606 _AC_LINK_IFELSE): Undo previous change, as it's no longer needed.
13607 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Don't bother with
13608 "</dev/null" since it's now done at the top of 'configure'.
13609 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
13610 * lib/autoconf/programs.m4 (_AC_PATH_PROG_FLAVOR_GNU): Likewise.
13611 Also, replace grep with shell pattern-matching, to save a process.
13613 2005-02-10 Paul Eggert <eggert@cs.ucla.edu>
13615 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
13616 _AC_LINK_IFELSE): Redirect stdin to /dev/null, in an attempt to
13617 avoid thinking that Allegro Common Lisp's "cl" command is a C++
13620 2005-02-09 Paul Eggert <eggert@cs.ucla.edu>
13622 * doc/autoconf.texi (Limitations of Usual Tools): Document that
13623 grep -q isn't portable. Improve grep -s explanation.
13624 Problem reported by Dan Manthey.
13626 2005-02-08 Paul Eggert <eggert@cs.ucla.edu>
13628 * doc/autoconf.texi (Special Shell Variables): Clarify
13629 PATH_SEPARATOR wording; fix typo in IFS. Reported by Gary V. Vaughan.
13631 2005-02-07 Paul Eggert <eggert@cs.ucla.edu>
13633 * doc/autoconf.texi: Use @acronym for DJGPP.
13634 Fix some @code's that should have been @env's, and vice versa.
13635 Sort environment variable names.
13636 Mention that shells no longer inherit IFS.
13637 Don't recommend PATH_SEPARATOR=';' so strongly.
13638 Mention that $RANDOM might expand to the empty string.
13639 "symlink" and "soft link" -> "symbolic link".
13640 Improve mktemp description (reported by Bruno Haible).
13642 2005-02-05 Paul Eggert <eggert@cs.ucla.edu>
13644 * tests/foreign.at (Libtool): Don't overquote AT_SETUP arg.
13645 * tests/m4sh.at (AS_DIRNAME, AS_BASENAME, AS_MKDIR_P, AS_HELP_STRING):
13647 * tests/semantics.at (AC_C_BIGENDIAN, AC_PATH_PROG & AC_PATH_PROGS):
13650 2005-02-04 Paul Eggert <eggert@cs.ucla.edu>
13652 * NEWS: Mention AT_COPYRIGHT.
13654 * tests/local.at (AT_CMP): Use diff directly on input files rather
13657 * lib/autoconf/programs.m4 (AC_PROG_SED): Don't look in
13658 /usr/xpg4/bin since that sed dumps core (at least on Solaris 8).
13660 2005-02-04 Noah Misch <noah@cs.caltech.edu>
13661 and Paul Eggert <eggert@cs.ucla.edu>

13665 (Substitute a 2000-byte string, Define to a 2000-byte string)
13666 (Substitute a newline, Define a newline): New tests.
13668 2005-02-04 Noah Misch <noah@cs.caltech.edu>
13670 * lib/m4sugar/m4sugar.m4 (m4_re_string, m4_re_word): Revert 2002-03-04.
13671 * tests/local.at (AT_CHECK_M4SUGAR): Add `m4sugar' to keywords.
13672 (AT_CHECK_ENV): Ignore LTLIBOBJS, FC variables, EGREP, FGREP, and SED.

13675 (m4_warn, m4_require: circular dependencies, m4_text_wrap): Strip
13676 excess test name quoting.
13677 * tests/semantics.at (AC_CHECK_HEADERS_OLD, AC_CHECK_HEADERS_NEW): Pass
13678 CPPFLAGS to `configure' instead of setting it in `configure'.
13680 * lib/m4sugar/m4sh.m4 (AS_UNAME): Try only /usr/bin/hostinfo, not
13681 any `hostinfo' in $PATH, since hostinfo.exe is a popular file name
13684 * lib/autoconf/fortran.m4 (AC_LANG(Fortran), AC_FC_SRCEXT):
13685 s/FC_SRCEXT/ac_fc_srcext/; s/FCFLAGS_SRCEXT/ac_fcflags_srcext/.

13715 * lib/m4sugar/m4sugar.m4 (m4_re_escape): Escape ?, ^, \, $ too;
13716 this fixes a bug tickled by the AT_CAPTURE_FILE change noted below.
13718 Try not to generated lines of unlimited length, as POSIX places a
13719 2047-byte limit on line length of portable text files.
13720 * lib/autoconf/general.m4 (AC_SUBST, AC_SUBST_FILE):
13721 Use newline as a separator, not space.

13734 * doc/autoconf.texi (Special Shell Variables): Mention _,
13735 BIN_SH, DUALCASE. Say that variables other than "status" are safe
13736 if they contain a lower-case letter. The DUALCASE problem was
13737 reported by Ralf Wildenhues.
13739 * bin/autoconf.as: Don't exit with status 0 after write failure
13740 with --help or --version.

13746 * doc/autoconf.texi (Limitations of Usual Tools):
13747 Unicos 9 sed limitations.
13748 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Try cf77 before fort77
13749 to get the option-enhanced interface on older Crays. Try ftn for
13750 Fortran 95 (newer Crays).
13752 2005-02-01 Paul Eggert <eggert@cs.ucla.edu>
13754 * man/Makefile.am (.x.1): Go back to the simple solution, but take
13755 care to echo the commands, so the user knows what's going on.
13756 Modified from a suggestion by Stepan Kasal.

13766 Based on a proposed patch by Ralf Wildenhues.
13768 * man/Makefile.am (.x.1): Make sure the required generated files
13769 are up to date. Problem and original solution proposed by Stepan Kasal.

13779 Simplify the implementation of m4_require (a.k.a. AC_REQUIRE).
13780 Update the long comment explaining it.
13782 m4_require no longer writes an ``is required by'' line to the
13783 execution stack. It contains only one bit of non-redundant
13784 information: that the macro was required, not called. And even
13785 this bit is useless in most situations: have you ever met a macro
13786 which both calls and requires the same macro?
13788 * lib/m4sugar/m4sugar.m4 (_m4_defun_pro): Don't push a diversion...
13789 (_m4_defun_pro_outer): ... only via this macro, for the outermost
13791 (_m4_defun_epi, _m4_defun_epi_outer): Complementarily.
13792 (m4_expansion_stack_pop): Remove the misplaced comment.
13793 (m4_require): Don't put the ``is required by'' line to the
13794 execution stack; slightly improve the out-of-a-defun error message.
13795 (_m4_divert_grow): New macro, counter for the temporary diversions.
13796 (_m4_require_call): Use it.
13797 * tests/m4sugar.at (m4_require): Expect output without the
13798 ``is required by'' messages.
13800 2005-01-28 Paul Eggert <eggert@cs.ucla.edu>
13802 * doc/autoconf.texi (Limitations of Usual Tools): Recommend X
13803 rather than x for expr.

14208 * lib/autoconf/functions.m4 (AC_FUNC_MEMCMP): Use
14209 "char c = '\200';" rather than "char c = 0x80;" as the

14274 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Don't check
14275 the $1_found variable, don't test whether the file is executable;
14276 Both things are checked ...
14277 (_AC_PATH_PROG_FEATURE_CHECK): ... here; AS_EXECUTABLE_P replaces
14278 the former ``test -f''.
14279 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Fix a typo.
14281 2004-11-10 Paul Eggert <eggert@cs.ucla.edu>

14286 2004-11-10 Derek R. Price <derek@ximbiot.com>
14288 * doc/autoconf.texi (Limitations of Usual Tools): Note `cp -r'
14289 limitations. Reorder paragraphs for clarity.
14291 2004-10-11 Paul Eggert <eggert@cs.ucla.edu>
14293 * doc/autoconf.texi: Standardize spelling of "Posix" (as opposed
14294 to "POSIX" or "@acronym{POSIX}"), and similarly for "DOS
14295 variants", "Unix", and some related minor wording fixups.
14297 (Shellology, Special Shell Variables): Document that the Zsh
14298 problem with NULLCMD was fixed in zsh 3.1.6-dev-18. Thanks
14299 to Alexandre Duret-Lutz for this info.

14310 2004-09-22 Paul Eggert <eggert@cs.ucla.edu>
14312 * doc/autoconf.texi (auindex): New macro.
14313 (AU_DEFUN): Use it to fix the bug when the index contained AC_AU_DEFUN.
14314 Problem reported by Stepan Kasal.
14316 2004-09-05 Paul Eggert <eggert@cs.ucla.edu>
14318 Fix problems reported by Andreas Buening in:

14320 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Set SHELL=/bin/sh
14322 * lib/autotest/general.m4 (AT_INIT): Don't assume /dev/null is
14323 readable; it's not true in OS/2-emx.
14325 2004-09-04 Paul Eggert <eggert@cs.ucla.edu>
14327 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): If xmkmf returns
14328 "/usr/include", clear ac_x_includes instead of leaving it as "no"
14329 (trivial change). Problem and patch reported by Andrew Church in:
14330 http://lists.gnu.org/archive/html/bug-autoconf/2004-04/msg00016.html
14332 2004-09-03 Paul Eggert <eggert@cs.ucla.edu>
14334 * doc/autoconf.texi: Give AC_DEFINE and AC_DEFINE_UNQUOTED
14335 three args in examples. Problem reported by Frederik Fouvry in:

14337 Also, fix some minor spacing and punctuation bugs.
14339 2004-09-02 Akim Demaille <akim@epita.fr>
14341 * doc/autoconf.texi (Limitations of Builtins): Swap "cd" and
14342 "case" to restore ordering.
14343 Reported by Stepan Kasal.
14345 2004-08-26 Akim Demaille <akim@epita.fr>

14359 * Makefile.cfg (wget_files): Remove config.guess, config.sub,
14360 texinfo.tex for now (done by hand now).
14361 * Makefile.maint (wget_files, cvs_files):
14362 Remove ansi2knr.c; nobody uses it.
14363 (ansi2knr.c-url_prefix): Remove.
14364 (cvs-update): Fix test for failure. I don't know why it ever
14367 * doc/autoconf.texi: Update URLs, some of which went stale.
14368 Use @uref rather than @href.
14370 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Have configure
14371 handle "--" as per POSIX. Suggested by Paul Pogonyshev.
14373 * config/config.guess, config/config.sub, config/elisp-comp,
14374 config/install-sh, config/mkinstalldirs, config/texinfo.tex,
14375 doc/fdl.texi, doc/standards.texi: Sync with master copy.
14377 * NEWS, TODO, configure.ac, bin/autoscan.in,
14378 bin/autoupdate.in, bin/ifnames.in, doc/autoconf.texi,
14379 doc/install.texi, lib/Autom4te/Configure_ac.pm,

14383 lib/m4sugar/m4sugar.m4, tests/local.at, tests/m4sh.at,
14384 tests/tools.at, tests/torture.at:
14385 Use "file name" rather than "filename" or "path",
14386 to be consistent with the terminology of the GNU coding standards.
14388 2004-08-19 Paul Eggert <eggert@cs.ucla.edu>
14390 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C),
14391 AC_C_LONG_DOUBLE): Undo 2004-06-04 change, as it didn't work with
14392 HP-UX 11.23 cc/aCC or Tru64 4.0 cc. Problem reported by Noah Misch in
14393 <http://lists.gnu.org/archive/html/autoconf/2004-07/msg00004.html>.
14395 More fixes to support spaces in the name of the build directory.
14396 This isn't a complete fix but it's an improvement.
14398 * bin/autoconf.as (autom4te_options): New var.
14399 Use it instead of appending to AUTOM4TE, so that we can allow
14400 spaces in the build directory's absolute name.
14401 * bin/autoheader.in ($autoconf): Allow spaces in file names.
14402 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP, _AT_CHECK,
14403 AT_CHECK_NOESCAPE): Likewise.
14404 * tests/wrapper.as (testdir, AUTOM4TE_CFG, autom4te_perllibdir,
14405 main program): Likewise.
14407 2004-08-18 Paul Eggert <eggert@cs.ucla.edu>
14409 * lib/autoconf/general.m4 (_AC_INIT_HELP): Quote $ac_popdir uses.

14413 2004-08-12 Paul Eggert <eggert@cs.ucla.edu>
14415 * doc/autoconf.texi (Function Portability): Document isinf and
14416 and isnan. From a suggestion by Kevin Ryde.
14418 * lib/Autom4te/General.pm (END): Return correct exit status even
14419 if unlink succeeds and sets $?. Needed with Solaris 8's perl 5.00503.
14421 2004-08-09 Paul Eggert <eggert@cs.ucla.edu>
14423 * tests/torture.at (Deep Package): Use configure.in, not configure.ac,
14424 for compatibility with Automake 1.4. Reported by J C Fitzgerald in
14425 <http://lists.gnu.org/archive/html/bug-autoconf/2003-08/msg00051.html>.
14427 2004-08-04 Alexandre Duret-Lutz <adl@gnu.org>
14429 * lib/autoconf/general.m4 (AC_REQUIRE_AUX_FILE): New empty macro.
14430 (AC_CANONICAL_BUILD): Call it to require config.sub and config.guess.
14431 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Likewise for install-sh.
14432 * doc/autoconf.texi (Input): Document AC_REQUIRE_AUX_FILE.
14433 * lib/autom4te.in (Automake-preselections): Preselect
14434 AC_REQUIRE_AUX_FILE. Automake 1.10 will trace it.
14436 2004-08-02 Alexandre Duret-Lutz <adl@gnu.org>
14438 * lib/autom4te.in (Automake-preselections): Preselect
14439 AC_CANONICAL_BUILD and AC_CANONICAL_TARGET. Automake 1.9.1 will
14442 2004-07-29 Paul Eggert <eggert@cs.ucla.edu>
14444 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): Set BIN_SH, for
14446 * doc/autoconf.texi (Shellology): Mention BIN_SH.
14447 Document problem with "`""`" in pdksh POSIX mode.
14449 2004-07-27 Paul Eggert <eggert@cs.ucla.edu>
14451 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): Use "set -o posix"
14452 with pdksh, too. Problem reported by Patrick Welche via
14454 * doc/autoconf.texi (Shellology): Note that set -o posix is
14455 useful for pkdsh, too.
14457 2004-06-24 Paul Eggert <eggert@cs.ucla.edu>
14459 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Require
14460 _AS_UNSET_PREPARE, so that we can use $as_unset directly.
14461 Don't fail if ENV or BASH_ENV is readonly.
14462 (AS_SHELL_SANITIZE): Don't fail if ENV, MAIL, MAILPATH, LC_ALL,
14463 etc. are read only. Problem reported by Ludovic Courtes.
14465 2004-06-23 Noah Misch <noah@cs.caltech.edu>
14467 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): If the shell is
14468 zsh, disable GLOB_SUBST to avoid backslash handling problems.
14471 2004-06-04 Paul Eggert <eggert@cs.ucla.edu>
14473 * doc/autoconf.texi (File System Conventions): Warn about
14474 names like "aux". Problem reported by Eric Blake.
14476 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY (C)): Use division
14477 by zero instead of array size, so that we can use any arithmetic
14478 constant expression (instead of requiring an integer constant
14479 expression). This allows us to test expressions like DBL_MAX <
14480 LDBL_MAX, which didn't conform to the C standard using the old
14482 (AC_C_LONG_DOUBLE): Put back in the tests for LDBL_MAX and LDBL_EPSILON,
14483 now that we can do floating-point tests at compile time.
14485 2004-06-02 Paul Eggert <eggert@cs.ucla.edu>
14487 * lib/autoconf/c.m4 (AC_C_LONG_DOUBLE): Don't check LDBL_MAX
14488 and LDBL_EPSILON, as the resulting expression isn't an
14489 integer constant expression and violates the C standard.
14490 Problem reported by Nelson H. F. Beebe. Also, check
14491 for "L" suffix, and check that long double doesn't have
14492 worse range or precision than double, that mixed-mode
14493 arithmetic doesn't generate a diagnostic, that double
14494 constants fit in long double.
14496 2004-06-03 Kevin Ryde <user42@zip.com.au>
14498 * doc/autoconf.texi (Function Portability): Add notes on free(NULL),
14499 malloc(0) and realloc(NULL,size).
14501 * doc/autoconf.texi (Shell Substitutions): Spelling error reported by
14504 2004-05-31 Paul Eggert <eggert@cs.ucla.edu>
14506 * lib/autoconf/headers.m4 (HAVE_STDBOOL_H): Detect _Bool bug
14507 in HP aC++/ANSI C B3910B A.05.55 [Dec 04 2003]. Problem reported
14510 2004-05-26 Paul Eggert <eggert@cs.ucla.edu>
14512 * doc/autoconf.texi (Limitations of Builtins): Mention that ! COMMAND
14513 can be rewritten using if-then-else. Suggested by Bruno Haible.
14515 2004-05-25 Paul Eggert <eggert@cs.ucla.edu>
14517 * doc/autoconf.texi (testsuite Scripts): Fix typo.
14518 Problem reported by Stepan Kasal.
14520 2004-05-24 Paul Eggert <eggert@cs.ucla.edu>
14522 * tests/Makefile.am (autoconfdir): Fix to match comment (trivial
14523 change). Patch reported by Ralf Wildenhues in
14524 <http://mail.gnu.org/archive/html/bug-autoconf/2004-05/msg00092.html>.
14526 * lib/autoconf/functions.m4 (AC_FUNC_MBRTOWC): Don't assume that a
14527 function F exists if the compiler and linker let you compile an
14528 expression like (F != 0). Recent versions of GCC optimize away
14529 the reference to F in that case, since every function address must
14530 be nonzero, so the link succeeds even if F does not exist.
14531 Problem reported by Manu in
14532 <http://mail.gnu.org/archive/html/bug-gnu-utils/2004-05/msg00060.html>.
14534 * doc/autoconf.texi (Systemology): Standardize on the spelling of
14535 "Unix". Many uses changed.
14536 (Limitations of Builtins): Explain better why the ! command isn't
14539 2004-05-22 Alexandre Duret-Lutz <adl@gnu.org>
14541 * lib/autom4te.in (Automake-preselections): Preselect
14542 LT_SUPPORTED_TAG in lieu of AC_LIBTOOL_TAGS.
14544 2004-05-19 Kevin Ryde <user42@zip.com.au>
14546 * doc/autoconf.texi (Function Portability): Add strerror_r, cross
14547 referencing AC_FUNC_STRERROR_R.
14549 * doc/autoconf.texi (Particular Functions): In AC_FUNC_CLOSEDIR_VOID,
14550 note pessimistic assumption when cross compiling.
14552 2004-05-16 Paul Eggert <eggert@cs.ucla.edu>
14554 * doc/autoconf.texi (Limitations of Make): Note that BSD make
14555 (until 2004) invoked subcommands with sh -e, contra POSIX.
14556 Reported by Kevin Ryde.
14558 2004-05-10 Eric Sunshine <sunshine@sunshineco.com>
14560 * programs.m4 (_AC_PROG_GREP): Fixed bug where PATH argument handed to
14561 _AC_PATH_PROG_FEATURE_CHECK contained leading whitespace (i.e.
14562 " $PATH:/usr/xpg4/bin"). This resulted in bogus tests, such as
14563 `test -f " /usr/bin/grep"', which _always_ failed.
14564 (AC_PROG_SED): Ditto bogus PATH fix.
14565 * autoconf.texi (AC_PROG_GREP): Properly document that this macro
14566 requires that grep correctly supports _multiple_ `-e' options, rather
14567 than stating only that grep should accept `-e'.
14569 2004-05-03 Paul Eggert <eggert@cs.ucla.edu>
14571 Port to C99, which requires that 'exit' be declared.
14573 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Use AC_INCLUDES_DEFAULT
14574 to ensure that stdlib.h is included.
14575 * lib/autoconf/functions.m4 (_AC_LIBOBJ_ALLOCA, AC_FUNC_SETPGRP,
14576 AC_FUNC_STRTOD, AC_FUNC_SETVBUF_REVERSED, AC_FUNC_FORK, _AC_FUNC_FORK,
14577 _AC_FUNC_VFORK, AC_FUNC_WAIT3): Likewise.
14578 * lib/autoconf/specific.m4 (AC_SYS_RESTARTABLE_SYSCALLS): Likewise.
14579 * lib/autoconf/types.m4 (AC_TYPE_GETGROUPS): Likewise.
14580 * lib/autoconf/headers.m4 (AC_HEADER_STDC): Include <stdlib.h>
14581 when using 'exit' in a test; C99 requires that 'exit' be declared.
14583 2004-05-02 Paul Eggert <eggert@cs.ucla.edu>
14585 * doc/autoconf.texi (Particular Programs): AC_PROG_GREP
14586 now prefers 'grep' implementations that accept -e.
14587 (Limitations of Usual Tools): Describe problems of traditional
14588 egrep and fgrep with long input lines, and of traditional grep
14590 * lib/autoconf/programs.m4 (AC_PROG_GREP): Check for -e, too.
14591 (_AC_PROG_GREP): Assume 3rd arg is properly quoted for the shell.
14592 All callers changed. Append /usr/xpg4/bin to the PATH, for
14594 (_AC_FEATURE_CHECK_LENGTH): Discard stderr, so we don't bother
14595 the user with complaints about multiple -e options.
14596 * tests/local.at (AC_STATE_SAVE): Use $GREP, not grep.
14597 Define it with AC_PROG_GREP.
14598 * configure.ac (AC_PROG_GREP): Add.
14599 * lib/freeze.mk (GREP): New macro.
14601 2004-05-02 Eric Sunshine <sunshine@sunshineco.com>
14603 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Consult $SHELL as
14604 a possible candidate only after all others fail, rather than
14605 consulting it first. This improves backward compatibility by
14606 better reflecting the way shell selection occurred in previous
14607 versions of Autoconf, and should help to avoid triggering latent
14608 problems in other packages, such as the one in Automake where zsh
14609 is not handled robustly:
14610 http://mail.gnu.org/archive/html/automake/2004-04/msg00095.html
14611 Although it is not Autoconf's responsibility to work around
14612 problems in Automake, it nevertheless makes sense to avoid
14613 introducing unnecessary incompatibilites.
14615 2004-04-22 Albert Chin-A-Young <china@thewrittenword.com>,
14616 Gary V. Vaughan <gary@gnu.org>
14618 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Don't guess
14619 how deeply nested we are when a suitable tool is found, set the
14620 ac_path_TOOL_found flag.
14621 (_AC_PATH_PROG_FEATURE_CHECK): Encapsulate knowledge of how deeply
14622 nested we are in this macro. Break out of all 3 nested loops if
14623 ac_path_TOOL_found is set.
14625 2004-04-21 Gary V. Vaughan <gary@gnu.org>
14627 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Break out
14628 of the _AS_PATH_WALK loop too if GNU flavor is found.
14630 2004-04-21 Alexandre Duret-Lutz <adl@gnu.org>
14632 * doc/autoconf.texi (Limitations of Make): Update documentation
14633 for `$<'. New entry `Long lines', based on a report from Simon
14634 Josefsson. Augment the documentation for SHELL = @SHELL@ with a
14635 paragraph about DJGPP, based on a mail from Richard Dawe.
14637 2004-04-20 Paul Eggert <eggert@twinsun.com>
14639 * tests/c.at (C keywords): Don't assume that GCC supports
14640 "restrict" and "inline", as sufficiently-old GCC versions do not
14641 (also, GCC configured to be in pedantic C89 mode does not).
14642 Problem reported by Sumit Pandya in:
14643 http://mail.gnu.org/archive/html/autoconf/2004-04/msg00092.html
14645 * lib/autoconf/c.m4 (_AC_PROG_CC_G, _AC_PROG_CXX_G): Don't
14646 consider -g to work if it generates warnings when plain compiles
14647 don't. Problem reported by Braden McDaniel in:
14648 http://mail.gnu.org/archive/html/autoconf-patches/2003-07/msg00014.html
14650 * doc/autoconf.texi (Slashes): New section, to document a problem
14651 reported by Jim Meyering in:
14652 http://mail.gnu.org/archive/html/bug-coreutils/2004-02/msg00060.html
14654 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Remove potential
14655 linker output files before linking, to work around IRIX 6 linker bug.
14656 Problem reported by Rainer Orth in:
14657 http://mail.gnu.org/archive/html/autoconf-patches/2004-02/msg00007.html
14659 2004-04-20 Gary V. Vaughan <gary@gnu.org>
14661 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Make the
14662 best tool so far counter rely on the tool path variable name to
14663 avoid checks for one tool being affected by the results of running
14664 the length check on a previous tool.
14666 * lib/autoconf/programs.m4 (_AC_PROG_GREP): Take an additional
14667 match expression argument, as different greps have different
14668 regular expression flavours.
14669 (AC_PROG_FGREP): Pass 'FGREP'. fgrep treats all match chars as
14671 (AC_PROG_EGREP): Pass 'EGREP$'.
14672 (AC_PROG_GREP): Pass 'GREP$'.
14674 2004-04-20 Albert Chin-A-Young <china@thewrittenword.com>
14676 * lib/autoconf/programs.m4 (AC_PROG_GREP): Cache variable
14677 is `ac_cv_path_GREP', not `oc_cv_path_GREP'.
14679 2004-03-29 Paul Eggert <eggert@twinsun.com>
14681 * doc/autoconf.texi (Particular Headers, Particular Types, Generic
14682 Types, Specific Compiler Characteristics, System Services,
14683 Obsolete Macros): Use 'long int', 'short int', 'unsigned int'
14684 etc. consistently instead of 'long', 'short', 'unsigned' etc.
14685 * lib/autoconf/c.m4 (AC_LANG_INT_SAVE(C), AC_C_BIGENDIAN): Likewise.
14686 * lib/autoconf/functions.m4 (AC_FUNC_MMAP, AC_FUNC_SELECT_ARGTYPES):
14688 * lib/autoconf/headers.m4 (AC_HEADER_SYS_WAIT): Likewise.
14689 * lib/autoconf/types.m4 (AC_TYPE_GETGROUPS, AC_TYPE_SIZE_T,
14690 AC_TYPE_OFF_T): Likewise.

14694 * tests/foreign.at (Libtool): Create an empty aclocal.m4, to
14695 pacify libtool 1.5.2. Fix quoting problems in sed command.
14697 2004-03-28 Paul Eggert <eggert@twinsun.com>
14699 * doc/autoconf.texi (Particular Structures): AC_STRUCT_TIMEZONE
14700 now defines HAVE_DECL_TZNAME if it is declared, when
14701 HAVE_STRUCT_TM_TM_ZONE is not defined.
14702 * lib/autoconf/types.m4 (AC_STRUCT_TIMEZONE): Implement this.
14703 Do not assume atoi. Rely on HAVE_DECL_TZNAME when testing
14706 2004-03-28 Steven G. Johnson <stevenj@fftw.org>
14708 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Corrected
14709 superfluous backslashing of quotes (") in sed expressions;

14795 * bin/Makefile.am ($(srcdir)/autoconf.in): Depend on

14804 AC_SUBST provides no portable way to escape literal newlines.
14806 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS): Ignore all
14807 flags of the form -lcrt*.o, not just -lcrt[01].o and -lcrtbegin.o.
14808 Darwin uses -lcrt2.o and there's little point to cataloging all
14809 the system variants. Partial fix reported by Andreas Waechter in:

14854 use AS_INIT_WITH_SHELL_FN.

14885 * lib/autoconf/general.m4 (_AC_INIT_COPYRIGHT): Add 1992 thorugh

14887 the 2003-05-22 change, which removed the older years from the list.
14888 * lib/autoconf/status.m4 (AC_OUTPUT): Update copyright date to 2004.

14901 _AC_PROG_GREP, and AC_PROG_SED.
14902 (_AC_FEATURE_CHECK_LENGTH): New helper macro for finding the
14903 longest input length accepted by a command.

14932 2004-01-26 Paul Eggert <eggert@twinsun.com>
14934 * doc/autoconf.texi (Default Includes): Include <stdint.h> even if
14935 HAVE_INTTYPES_H is defined. This is needed on Tru64 5.1b with
14936 Compac C V6.5-207 (dtk), which defines uintmax_t in <stdint.h> but
14937 not <inttypes.h>. Problem reported by Tim Mooney in
14938 <http://mail.gnu.org/archive/html/bug-coreutils/2004-01/msg00147.html>.
14939 * lib/autoconf/headers.m4 (_AC_INCLUDES_DEFAULT_REQUIREMENTS):
14942 * lib/autoconf/programs.m4 (AC_PROG_SED): Use diff, not sed;
14943 otherwise "make check" fails because it forbids cmp (I guess
14944 because cmp treats files as binary on DOS-like systems).
14946 * tests/mktests.sh: Update copyright date to 2004, since some tests
14947 have changed in 2004.
14949 2004-01-23 Gary V. Vaughan <gary@gnu.org>

14952 non-truncating sed or gsed program in PATH.

14957 2004-01-15 Paul Eggert <eggert@twinsun.com>
14959 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Try -std, not -std1, since
14960 -std1 disables some useful extensions on Tru64. Problem reported
14961 by N. Lichtmaier in
14962 <http://mail.gnu.org/archive/html/autoconf/2004-01/msg00100.html>.
14964 2004-01-14 Paul Eggert <eggert@twinsun.com>
14966 * doc/autoconf.texi (Programming in M4sh): Document that
14967 AS_MKDIR_P succeeds if the destination is a symbolic link
14968 to an existing directory.
14969 (Limitations of Usual Tools): Note that mkdir -p might not
14970 succeed on symlinks to directories.
14972 2004-01-13 Paul Hilfinger <hilfinger@CS.Berkeley.EDU>
14974 * lib/autoconf/autoupdate.m4 (AU_DEFUN): Grammar fix in comment.

14984 2004-01-10 Jim Meyering <jim@meyering.net>
14986 * doc/autoconf.texi (Running the Preprocessor): Correct grammar.
14988 2004-01-09 Paul Eggert <eggert@twinsun.com>
14990 * lib/autoconf/general.m4: Fix bug: AC_CHECK_SIZEOF evokes a warning
14991 with `autoconf -Wall,error'. Bug reported by Eric Blake in:
14992 http://mail.gnu.org/archive/html/autoconf-patches/2004-01/msg00000.html
14993 (_AC_COMPUTE_INT_COMPILE): Invoke _AC_COMPILE_IFELSE, not
14994 AC_COMPILE_IFELSE, since we now assume our caller invokes
14995 AC_LANG_COMPILER_REQUIRE, for symmetry with _AC_COMPUTE_INT_RUN.
14996 (_AC_COMPUTE_INT_RUN): Likewise, for _AC_RUN_IFELSE instead
14997 of AC_RUN_IFELSE; this avoids the warning mentioned above.
14998 (_AC_COMPUTE_INT): Invoke AC_LANG_COMPILER_REQUIRE.
15000 2004-01-07 Paul Eggert <eggert@twinsun.com>
15002 * lib/autoconf/general.m4 (_AC_LIBOBJS_NORMALIZE): Avoid \$ inside
15003 `"'...'"`, as it's confusing (and I suspect it may not work on
15004 some platforms). The code was incorrect anyway, as it assumed
15005 that \$ evaluated to itself in that context. Reported by
15006 Alexandre Duret-Lutz.
15008 2004-01-07 Alexandre Duret-Lutz <adl@gnu.org>
15010 * lib/autom4te.in (Automake-preselections): Preselect AC_LIBTOOL_TAGS
15011 and _LT_AC_TAGCONFIG.

15038 * lib/autoconf/general.m4 (AC_ARG_PROGRAM):
15039 Use "rm -f" to remove conftest.sed, not plain "rm".
15040 Bug reported by David Relson in
15041 <http://mail.gnu.org/archive/html/autoconf/2004-01/msg00011.html>.
15043 * Makefile.am (autom4te-update):
15044 Replace "rm -rf" and "rm -fr" with "rm -f -r", as POSIX requires.

15061 -c -o might not work. From a suggestion by Kevin Ryde.
15062 (C Compiler, Generating Sources, Limitations
15063 of Usual Tools, Limitations of Make, Making testsuite Scripts):
15064 Don't put '-o' after non-options, as POSIX doesn't allow this.
15065 Mention that cc's name might be gcc or c89 or whatever.
15067 2004-01-04 Kevin Ryde <user42@zip.com.au>

15092 * tests/atlocal.in: Store the result here.

15097 (AT_CHECK_AUTOCONF): Test for the configure script syntax.
15098 * tests/tools.at (Syntax of the shell scripts): Simplify

15366 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Omit quoted
15367 -mGLOB_options_string stuff for Intel ifc, which can cause

15391 * lib/autoconf/fortran.m4 (_AC_PROG_FC_G): Use language-specific
15392 cache variable instead of $G77 to decide whether to include -O2,
15393 since $G77 is specific to Fortran 77.

15397 * lib/autoconf/fortran.m4 (AC_FC_FREEFORM): Support Absoft "-f
15398 free" flag. Re-order flags tested into rough order of popularity.
15400 2003-10-03 Steven G. Johnson <stevenj@alum.mit.edu>
15402 * lib/autoconf/fortran.m4 (AC_PROG_FC): Reverse the order of the
15403 arguments so that it can be used with syntax identical to
15404 AC_PROG_F77, and so that we can more easily decide to
15405 remove/deprecate the DIALECT optional argument in the future if it
15406 proves troublesome.
15407 (AC_FC_FREEFORM): Exit 77 upon failure to fix test suite for
15408 non-freeform-supporting compilers. Document freeform flags.
15410 2003-10-03 Akim Demaille <akim@epita.fr>
15412 * configure.ac: Look for emacs, not macs.

15471 Problem reported by Lars J. Aas in
15472 <http://mail.gnu.org/archive/html/autoconf/2003-07/msg00042.html>.
15473 (_AS_MKDIR_P_PREPARE): Change "rm -fr ./-p" to the more-conservative
15474 "test -d ./-p && rmdir ./-p". Suggested by Andreas Schwab in:
15475 http://mail.gnu.org/archive/html/autoconf-patches/2003-09/msg00039.html
15477 2003-09-26 Akim Demaille <akim@epita.fr>
15479 * lib/autoconf/status.m4 (_AC_OUTPUT_COMMANDS): Make sure the
15480 directory for AC_CONFIG_COMMANDS' first argument exists.
15481 This makes valid the invocation of _AC_SRCPATH that follows.
15482 Reported by Eric Sunshine.
15483 * doc/autoconf.texi (Configuration Commands): Adjust.
15485 2003-09-26 Akim Demaille <akim@epita.fr>

15506 The test suite are sometimes assigning timings incorrectly.
15507 Reported by Henk Krus.
15508 Diagnosed by Nicolas Joly.
15510 * lib/autotest/general.m4 (AT_CLEANUP): Rename AT_help as
15512 Instead of making AT_help a sequence of assignments to grow
15513 $at_help_all, just make AT_help_all be the growing contents of
15514 $at_help_all, and make a single assignment in...
15516 (at_times_skip): Flip the meaning and rename as...
15517 (at_times_p): this.
15518 (AT_INIT): When summarizing the test that ran, remove
15519 $at_times_file after use, and check it is present before trying to

15528 (ifnames): chmod -w.
15529 * tests/wrapper.as (AUTOCONF, AUTOM4TE, ): Point to tests/
15530 executables, not bin/ executables! Otherwise all the magic needed
15531 to find non installed files is turned off. This caused a failure
15532 of test 40 and 41 that ran aclocal 1.8 which in turn ran autom4te
15533 as found in its environment (sent by tests/autoreconf): pointing
15534 to bin/autom4te that could not find its files.
15535 * tests/mktests.sh: Force the replacement of generated files, for
15536 the sake of "mv" program that are interactive when overwriting a
15538 * config/install-sh: Upgrade from CVS Automake.

15543 versus test -L issues.
15545 2003-09-23 Daniel Jacobowitz <drow@mvista.com> and
15546 Paul Eggert <eggert@twinsun.com>
15548 Trivial change to support GCC's configuration procedure.
15549 * lib/autoconf/c.m4 (AC_PROG_CPP_WERROR): New macro.
15550 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): Don't warn
15551 about inconsistency if the preprocessor is set to give errors for

15584 willing to edit the output files.
15586 2003-09-10 Akim Demaille <akim@epita.fr>

15589 and AC_FC_FREEFORM.
15590 * tests/mktests.sh: Skip AC_FC_SRCEXT.
15591 * lib/autoconf/fortran.m4 (AC_FC_SRCEXT, AC_FC_FREEFORM): Likewise.

15608 From a suggestion by Ian Lance Taylor in
15609 <http://mail.gnu.org/archive/html/autoconf/2003-09/msg00044.html>.
15611 2003-09-05 Paul Eggert <eggert@twinsun.com>
15613 * lib/autoconf/fortran.m4 (AC_FC_FREEFORM): Try -ffree-form too,

15631 2003-09-02 Steven G. Johnson <stevenj@alum.mit.edu>
15633 Add support for newer Fortran dialects. The F77 interface is
15634 unchanged, and continues to support Fortran 77. New FC macros
15635 correspond to all the old F77 macros, with output variables FC,
15636 FCFLAGS, and FCLIBS. AC_PROG_FC defaults to picking the newest
15637 available dialect, but older dialects can be specified. There are
15638 new macros AC_FC_SRCEXT to set the source extension, and
15639 AC_FC_FREEFORM to accept free-form source files.
15641 * lib/autoconf/c.m4 (_AC_LANG_PREFIX(C), _AC_LANG_PREFIX(C++)):
15643 (AC_LANG_PROGRAM(C)): Invoke _AC_LANG_PROGRAM_C_FC_HOOKS if defined.

15765 2003-08-21 Akim Demaille <akim@epita.fr>
15767 First stab at preserving warnings between calls to autom4te,
15768 including when the cache is used.
15770 There are still several issues: (i) there are too many runs of m4
15771 (one for include, one for warnings, and some more), (ii) warnings
15772 spreading on several lines are not handled gracefully, (iii) the
15773 code meant to have the call stack display for errors does not work
15774 (its handling should move from m4 to autom4te).
15776 * bin/autom4te.in Autom4te::Channels, Autom4te::ChannelDefs):
15778 (@preselect): Add m4_warn.
15779 ($exit_status): Remove, use $exit_code.
15780 ($help): Use Autom4te::ChannelDefs::usage.
15781 (&handle_m4): No longer define the m4_warnings.
15782 At each run, extract and report the warnings.
15783 Always cache the result, including if the exit status is on
15784 failure, since if nothing changes, we should result in the same
15785 failure, hence we can use the cache.
15786 * lib/m4sugar/m4sugar.m4 (m4_warning_ifelse, _m4_warning_ifelse)
15787 (_m4_warning_error_ifelse, __m4_warning_error_ifelse, _m4_warn):
15789 (m4_warn): Redefine as a do-nothing: it is its invocation that
15790 matters, as warnings are now reported via traces.
15791 * lib/autoconf/general.m4 (AC_DIAGNOSE): Don't make it a copy of
15792 the contents of m4_warn: make it _call_ m4_warn, so that tracing
15793 the latter reveals calls to the former.
15797 * tests/m4sugar.at (m4@&t@_warn): Use existing warning categories.

15830 * bin/autoupdate.in, bin/autoheader.in, bin/autoreconf.in,
15831 * bin/autom4te: Adjust.
15832 In particular, be Autoconf tools are really silent when properly
15833 working, bind the verbosity of the 'note' channel to $verbose.
15834 * lib/Autom4te/General.pm (&find_file, &mtime, &update_file)

15958 * lib/autotest/general.m4 (AT_INIT): Report a single config.log,
15959 not all of them. This fixes 1. the fact that when testing
15960 Autoconf there are many many config.log, 2. the incorrect use of
15961 top_srcdir to find config.log.
15962 Don't mix the detailed output of failed test with the summary of
15963 failures. Rather, append detailed log afterwards.
15965 2003-06-23 Akim Demaille <akim@epita.fr>
15967 * tests/local.at (AT_CHECK_CONFIGURE): Adjust to the verbose being

16050 2003-05-23 Alexandre Duret-Lutz <adl@gnu.org>
16052 * lib/Autom4te/General.pm (END): Rewrite exit code processing.
16053 Do not call `_exit()', simply modify `$?'.
16054 (xsystem): Reset $! before running system, and check it afterward.
16055 * tests/tools.at (autoupdating AC_PREREQ): Expect exit status
16056 63 for version mismatches.
16058 2003-05-23 Akim Demaille <akim@epita.fr>
16060 * lib/autoconf/status.m4: Prefer "TAB-SP" to "SP-TAB", because of

16082 * lib/autoconf/c.m4 (_AC_PROG_CXX_EXIT_DECLARATION):
16083 Remove `#include <stdlib.h>' from the list; we should never
16084 make confdefs.h include <stdlib.h> or <cstdlib>, because the
16085 resulting namespace pollution would cause other tests to fail.
16086 Configure scripts run with some older versions of g++ and HP's
16087 aCC would fail due to such an #include. Problems reported by
16088 Matthew Mueller in <http://bugs.debian.org/120704> and by
16090 <http://mail.gnu.org/archive/html/autoconf/2003-05/msg00063.html>.
16091 In the test, use the test declaration before including <stdlib.h>,
16092 as that's closer to how it'll be used.
16094 2003-05-23 Akim Demaille <akim@epita.fr>
16096 * doc/autoconf.texi (Header Portability): ucred.h.
16099 2003-05-22 Paolo Bonzini <bonzini@gnu.org>
16101 Overhaul Autotest's logging: generate separate log files
16102 in testsuite.dir/NNN/testsuite.log, and append them to
16103 testsuite.log instead of re-running the test verbosely.
16105 * lib/autotest/general.m4 (AT_INIT): Use a single redirected
16106 file descriptor, write 0 to at_status_file instead of setting
16107 at_status=0, initialize some new variables (at_status_file,
16108 at_group_log, at_suite_log, at_tee_pipe). Remove the cruft
16109 to rerun the tests, instead append the at_group_log to the
16110 at_suite_log when a test fails.
16111 (AT_SETUP): pipe the test case's output into at_tee_pipe,
16112 with the AS_MESSAGE_LOG_FD redirected to stdout.
16113 (AT_CLEANUP): save the output status in $at_status_file
16114 and restore it, redirect the AS_MESSAGE_LOG_FD back to
16115 its original place.
16116 (AT_CHECK): since tests are run with a redirected stdout,
16117 and used to be re-run in verbose mode, turn some $at_verbose
16118 into echo, and don't redirect the output of testing stdout

16245 longer updates aclocal.m4 if useless, (ii) if a file m4_included
16246 by aclocal.m4 is changed it might require the importing of another
16247 m4 extension file, i.e., aclocal must be run.

16520 _AC_PROG_PREPROC_WORKS_IFELSE): Use <limits.h> if __STDC__ is
16521 defined, to support freestanding compilers. This should fix the
16522 bug reported by Momchil Velkov in

16525 * doc/autoconf.texi (Obsolete Macros): Fix typos (insert empty

16621 Reported by Ezra Peisach.
16623 2002-11-05 Akim Demaille <akim@epita.fr>
16625 * lib/autoconf/autoheader.m4 (_AH_TEMPLATE_OLD, _AH_VERBATIM_OLD):
16627 We _have_ to stop using the old compatibility scheme that tried to
16628 avoid useless backslashes because Libtool 1.4.3 contains a
16629 AC_DEFINE([error_t], [int],
16630 [Define to a type to use for \`error_t' if it is not
16631 otherwise available.])
16632 We _have_ to quote the single quote and backslashes with \. The
16633 old compatibility scheme saw that ` was backslashed, and therefore
16634 did not quote the single quote. Hence before this patch, Autoconf
16635 was not compatible with Libtool.

17026 Reported by Alexandre Duret-Lutz.
17028 * bin/autom4te.in (&parse_args): Do not prepend `--reload-state'

17089 * bin/autoreconf.in (&autoreconf): Run autopoint before the first
17090 aclocal invocation, as Gettext macros might not be visible to

17121 * lib/autoconf/headers.m4, lib/autoconf/libs.m4,
17122 * lib/autoconf/specific.m4, lib/autoconf/types.m4: here.
17124 2002-09-28 Akim Demaille <akim@epita.fr>
17126 * tests/torture.at (Configuring subdirectories): Be robust to
17127 users who use config.site to require for a cache: in this case,
17128 the two last configure runs, using two different sets of
17129 arguments, trigger a legitimate error.
17131 2002-09-28 Akim Demaille <akim@epita.fr>
17133 * tests/m4sh.at (Functions Support, Functions and return Support):
17136 2002-09-28 Akim Demaille <akim@epita.fr>
17138 * bin/Makefile.am (ETAGS_SH, ETAGS_PERL): Update: ifnames and
17139 autoheader are Perl programs.
17140 (autoconf, autoheader, autoreconf, autoupdate, ifnames, autoscan)
17141 (autom4te): Specify that the sources are in the $srcdir.

17149 * lib/autoscan/autoscan.pre (AWK, BISON, INSTALL, LEX, LN, MAKE)
17150 (RANLIB, YACC, awk, bison, byacc, flex, gawk, install, lex, ln)
17151 (make, mawk, nawk, ranlib, yacc): Similarly, move to...

17164 * lib/freeze.mk (autoconf_m4f_dependencies): Add autoscan.m4.
17165 (.m4.m4f): Don't pass --prepend-include, since that's done by
17166 tests/autom4te itself.
17167 * lib/autoscan/Makefile.am: Include freeze.mk.
17168 (autoscan.list): New target --this file is no longer a source.
17169 (autoscan.pre): New file.
17171 2002-09-28 Akim Demaille <akim@epita.fr>
17173 * bin/autoscan.in (@kinds): Make them singular.
17175 (&init_tables): When --debug, report the list of rules to ease
17176 tracking changes in autoscan.list.
17177 * lib/autoscan/autoscan.list (function): Strip comments, sort.
17179 2002-09-28 Akim Demaille <akim@epita.fr>
17181 * lib/autoscan/functions, lib/autoscan/headers,
17182 * lib/autoscan/identifiers, lib/autoscan/makevars,
17183 * lib/autoscan/programs: Merge into...
17184 * lib/autoscan/autoscan.list: this.
17185 * bin/autoscan.in (&init_tables): Adjust.
17187 2002-09-28 Akim Demaille <akim@epita.fr>
17189 * lib/autoscan/functions, lib/autoscan/headers,
17190 * lib/autoscan/identifiers, lib/autoscan/makevars,
17191 * lib/autoscan/programs: Make the `kind' explicit, i.e., each
17192 `functions' line is now prefixed with `function:'.
17193 * bin/autoscan.in (&init_tables): Adjust.
17195 2002-09-28 Akim Demaille <akim@epita.fr>
17197 From now on, autoscan files must always map a macro name to a
17198 word: there is no `default' macro for autoscan.
17200 * bin/autoscan.in (&init_tables): Reject entries with no macro at
17202 * lib/autoscan/functions, lib/autoscan/headers: Make the macro
17205 2002-09-28 Akim Demaille <akim@epita.fr>
17207 * bin/autoscan.in (%c_keywords): Remove.
17208 (&used): Keep only track of the words we might be interested in.
17209 (&output_kind): It is no longer needed to look for non active
17212 2002-09-27 Akim Demaille <akim@epita.fr>
17214 * lib/autoconf/functions.m4 (AC_FUNC_MBRTOWC): New, stolen from

17216 * lib/autoscan/functions: Adjust.
17217 * doc/autoconf.texi (Particular Functions): Adjust.
17219 2002-09-27 Akim Demaille <akim@epita.fr>

17223 Thanks to Bill Moseley and Paul Eggert.
17224 * lib/m4sugar/m4sh.m4 (AS_TMPDIR): $2 is the directory into which
17225 the tmpdir must be created.
17226 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Have the tmp
17227 dir be in the build tree, instead of $TMPDIR.
17229 2002-09-27 Akim Demaille <akim@epita.fr>
17231 * bin/autoscan.in: Improve the comments.
17232 (&parse_args): Drop obsolete undocumented options.

17239 * bin/autoreconf.in: Clarify that -s is meaningless without -i.
17240 Reported by Ralf Corsepius.
17241 * doc/autoconf.texi (autoreconf Invocation): Likewise.
17243 2002-09-26 Akim Demaille <akim@epita.fr>
17245 Single suffix rules and seperated dependencies are not portable.
17247 * doc/autoconf.texi (Installation Directory Variables): Update.
17248 (Limitations of Make): Some about `Single Suffix Rules and
17249 Separated Dependencies'.
17250 * bin/Makefile.am (autoconf, autoheader, autoreconf, autoupdate)
17251 (ifnames, autoscan, autom4te): Un-factor into several rules.
17253 2002-09-25 Paul Eggert <eggert@twinsun.com>
17255 * BUGS (Interoperability bugs): New section. Mention libtool
17256 1.4.2, configure.ac, and AC_CONFIG_AUX_DIR interoperability bug.
17258 2002-09-24 Paul Eggert <eggert@twinsun.com>
17260 Fix a portability bug reported by Alexandre Duret-Lutz: Solaris 8
17261 make handles suffix-rules differently from GNU make.
17263 * bin/Makefile.am (SUFFIXES, .in): Remove.
17264 (autoconf autoheader autoreconf autoupdate ifnames autoscan autom4te):
17265 Move the body of the old .in rule here.
17267 2002-09-16 Akim Demaille <akim@epita.fr>
17269 i960 compilers create `b.out' files by default.
17270 Reported by Ralf Corsepius.
17272 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT): Remove b.out files.
17273 (_AC_COMPILER_EXEEXT_DEFAULT): Adjust to b.out.
17275 2002-09-13 Paul Eggert <eggert@twinsun.com>
17277 * doc/autoconf.texi (Particular Headers): Remove obsolete
17278 reference to `struct timezone' in the description of
17281 2002-09-13 Akim Demaille <akim@epita.fr>
17285 * config/config.sub, config/config.guess: Update.
17286 * Makefile.maint: Update from bits of the Coreutils 4.5.1.
17287 * Makefile.am: Adjust.
17289 2002-09-13 Akim Demaille <akim@epita.fr>
17291 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Suggest
17292 reading config.log when the compiler is rejected.
17293 Suggested by Guido Draheim.
17295 2002-09-13 Akim Demaille <akim@epita.fr>
17297 * bin/autoreconf.in: Don't use Cwd::chdir, since in its internals
17298 (chdir_init) might hang when stat'ing mounted directories.
17299 Reported by Vance Shipley.
17301 2002-09-12 Akim Demaille <akim@epita.fr>
17303 * bin/autoscan.in (&parse_args): Pass a reference to the lists, not
17306 2002-09-12 Akim Demaille <akim@epita.fr>
17308 * doc/autoconf.texi (Defining Symbols): Present two different
17309 prototypes for AC_DEFINE and AC_DEFINE_UNQUOTED to emphasize the
17310 difference between 1 argument calls, and 2-3 argument calls.
17312 2002-09-12 Peter Eisentraut <peter_e@gmx.net>
17314 * doc/autoconf.texi: Review grammar and punctuation.
17316 2002-09-11 Paul Eggert <eggert@twinsun.com>
17318 * doc/autoconf.texi: Fix minor formatting, spelling, and
17320 (Defining Symbols): Explain that AC_DEFINE(var) defaults to 1, but
17321 AC_DEFINE(var,,description) does not; and the AC_DEFINE(var) case
17324 2002-09-11 Akim Demaille <akim@epita.fr>
17326 * doc/autoconf.texi (Questions): Rename as...
17328 (Defining Directories): New.
17330 2002-09-09 Akim Demaille <akim@epita.fr>
17332 * doc/autoconf.texi (Making testsuite Scripts): Update.
17333 Suggested by Nishio Futoshi.
17335 2002-09-09 Koji Arai <JCA02266@nifty.ne.jp>
17337 * doc/autoconf.texi (Making testsuite Scripts): Use `@@' where a
17338 plain `@' is wanted.
17340 2002-09-09 Akim Demaille <akim@epita.fr>
17342 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Keep the
17343 `duplicates', since the algorithm was too naive and could keep
17344 `--prefix=1 --prefix=2 --prefix=1' as `--prefix=1 --prefix=2', and
17345 keep `--prefix foo --prefix bar' as `--prefix foo bar'.
17346 Reported by Ralf Corsepius.
17347 * tests/torture.at (Configuring subdirectories): Exercise these
17350 2002-09-09 Akim Demaille <akim@epita.fr>
17352 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Use $srcdir when
17353 looking for a replacement file.
17354 * lib/autoconf/general.m4 (AC_CHECK_DECLS): Check that the
17355 directory is relative.
17356 * doc/autoconf.texi (Generic Functions): Clarify the replacement
17357 directory definition.
17358 Reported by Andreas Schwab and Jim Meyering.
17360 2002-09-06 Akim Demaille <akim@epita.fr>
17362 * doc/autoconf.texi (Setting Output Variables): Clarify what
17363 precious variables are.
17364 Suggested by Pontus Skoeld.
17366 2002-09-05 Akim Demaille <akim@epita.fr>
17368 * bin/Makefile.am (autoconf, autoheader, autoreconf, autoupdate)
17369 (ifnames, autoscan, autom4te): Since we don't only depend on
17370 configure.ac variables (such as VERSION etc.), but also on prefix
17371 and so forth, depend on Makefile, not configure.ac.
17372 Reported by Alexandre Duret-Lutz.
17373 * doc/autoconf.texi (Installation Directory Variables): Adjust.
17375 2002-09-05 Kevin Ryde <user42@zip.com.au>
17377 * doc/autoconf.texi (Limitations of Make): HP-UX trailing backslashes
17378 doesn't seem to be confined to ia64, just say "some versions".
17380 2002-09-04 Akim Demaille <akim@epita.fr>
17382 * Makefile.am, doc/Makefile.am: Remove pdf targets, handled by
17384 * Makefile.am (maintainer-clean-local): Remove.
17385 (MAINTAINERCLEANFILES): Remove COPYING.
17387 2002-09-03 Paul Eggert <eggert@twinsun.com>
17389 * doc/autoconf.texi (Configuration Commands): Remove obsolete
17390 example for AC_CONFIG_COMMANDS_PRE. Problem reported by Marcus
17393 2002-09-03 Akim Demaille <akim@epita.fr>
17395 * configure.ac: Bump to 2.53d.
17396 * Makefile.am (AUTOMAKE_OPTIONS): Require 1.6c, i.e., CVS Automake
17397 as of today, on Automake's team suggestion.
17399 2002-09-03 Akim Demaille <akim@epita.fr>
17403 2002-09-02 Akim Demaille <akim@epita.fr>
17405 * bin/autom4te.in (parse_args): Don't honor AUTOM4TE_PATH and
17407 * configure.ac: Disable SITE_MACRO_DIR.
17409 2002-09-02 Jim Meyering <meyering@lucent.com>
17411 * doc/autoconf.texi (AC_SYS_POSIX_TERMIOS): Reflect renaming: s/am/ac/,
17412 i.e., change am_cv_sys_posix_termios to ac_cv_sys_posix_termios.
17413 Also, tweak grammar: s/make sure to/be sure to/.
17415 2002-09-02 Paul Eggert <eggert@twinsun.com>
17417 * doc/autoconf.texi (Limitations of Builtins): Explain why logical
17418 directory names are generally preferable to physical names.
17420 2002-09-02 Akim Demaille <akim@epita.fr>
17422 * lib/Autom4te/General.pm (&update_file): s/die/error/.
17423 Reported by Raja R. Harinath.
17424 * bin/autoheader.in, bin/autoreconf.in, bin/autoscan.in,
17425 * bin/autoupdate.in: Use error instead of die.
17427 2002-09-01 Paul Eggert <eggert@twinsun.com>
17429 * tests/mktests.sh (ac_exclude_egrep, au_exclude_egrep): Use
17430 ordinary shell concatenation rather than echo+tr+sed command that
17431 runs afoul of a long-line-related sed bug in Solaris 8.
17433 * bin/autoheader.in (parse_args): --warning -> --warnings.
17435 * bin/autoconf.as: Work even if "ls" outputs "FOO not found" to
17436 stdout, as traditional "ls" does.
17437 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT,
17438 _AC_COMPILER_EXEEXT_O): Likewise.
17439 * doc/autoconf.texi (Limitations of Usual Tools): Add "ls".
17441 * bin/autoconf.as: Add --prepend-include option. This patch was
17442 applied to bin/autoconf.in in the 2002-07-17 patch by Mark D. Roth,
17443 but bin/autoconf.in is generated automatically from bin/autoconf.as.
17445 * bin/autoconf.in, configure: Regenerate.
17447 * doc/autoconf.texi (Special Shell Variables): Mention
17448 ENV, MAIL, MAILPATH, PS1, PS2, PS4. Index PWD.
17450 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Unset ENV, MAIL,
17451 MAILPATH and set PS1, PS2, PS4 to default values, to work
17452 around bug in pre-3.0 UWIN ksh reported by Bruce Lilly.
17453 For LC_ALL etc, first try to set to "C" as POSIX requires and as
17454 the Autoconf documentation specifies; fall back to "unset" only if
17455 this fails. Use a shell for-loop for this rather than an m4 loop,
17456 to shorten the output script.
17458 2002-08-30 Paul Eggert <eggert@twinsun.com>
17460 * doc/autoconf.texi (Special Shell Variables): Mention POSIX
17461 1003.1-2001's requirements for CDPATH. Give a simpler workaround
17462 for the CDPATH problem. Document PWD.
17463 (Limitations of Builtins): Document the problem that "cd $foo" and
17464 "ls $foo" may refer to different directories in shells conforming
17465 to POSIX 1003.1-2001. Use PS1 rather than CDPATH for "unset"
17466 example, since the old example is now out of date.
17468 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Reject FOO if "cd
17469 FOO" and "ls FOO" talk about different directories; this catches
17470 problems when POSIX 1003.1-2001 "cd" fails due to symlink
17473 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Use AS_UNSET instead
17474 of rolling our own unset.
17475 (_AS_PREPARE): $as_unset CDPATH instead of AS_UNSETting it, since
17476 in practice we needn't worry about CDPATH if unset doesn't work.
17478 * Makefile.in, aclocal.m4, bin/Makefile.in,
17479 config/Makefile.in, doc/Makefile.in, lib/Makefile.in,
17480 lib/Autom4te/Makefile.in, lib/autoconf/Makefile.in,
17481 lib/autoscan/Makefile.in, lib/autotest/Makefile.in,
17482 lib/emacs/Makefile.in, lib/m4sugar/Makefile.in, man/Makefile.in,
17483 tests/Makefile.in: Regenerate with Automake 1.6.3.
17485 * config/config.guess, config/config.sub, config/mkinstalldirs:
17488 * configure: Regenerate with self.
17490 2002-08-30 Kevin Ryde <user42@zip.com.au>
17492 * doc/autoconf.texi (Limitations of Usual Tools): Notes on "cc"
17495 2002-08-29 Rainer Orth <ro@TechFak.Uni-Bielefeld.DE>
17497 * bin/autom4te.in (Request::load): Correctly test for "do" read
17500 2002-08-29 Akim Demaille <akim@epita.fr>
17502 * lib/Autom4te/General.pm (&xqx): New.
17503 (&xsystem): Use WIFEXITED and WEXITSTATUS instead of decoding $? by
17504 hand, which is not portable.
17506 * bin/autom4te.in: Use them.
17507 Use &error instead of die.
17508 * tests/m4sugar.at (m4_warn, m4_require: circular dependencies):
17511 2002-08-17 Paul Eggert <eggert@twinsun.com>
17513 * lib/autoconf/fortran.m4 (AC_PROG_F77): Remove fc from the
17514 default list of compilers to try, since it was long ago superseded
17515 by the ksh fc builtin. Suggested by Steven G. Johnson.
17517 2002-07-31 Alexandre Duret-Lutz <duret_g@epita.fr>
17519 * doc/autoconf.texi (Invoking autom4te): End the option table,
17520 fixing a bug introduced by the previous patch.
17521 (Limitations of Make): Add a 'target lookup' subentry in the
17522 'VPATH' entry. Rewrite all `make' occurences as `@command{make}'.
17524 2002-07-29 Mark D. Roth <roth@feep.net>
17526 * bin/autom4te.in: Remove --include-envvar and --site-macro-subdir
17527 options and use $AUTOM4TE_PATH.
17528 * doc/autoconf.texi: Remove documentation of autom4te
17529 --include-envvar and --site-macro-subdir options and document
17530 use of $AUTOM4TE_PATH.
17531 * lib/autom4te.in: Remove --include-envvar and --site-macro-subdir
17532 arguments from each language section.
17534 2002-07-29 Paul Eggert <eggert@twinsun.com>
17536 * doc/install.texi: Include copyright symbol in copyright notice.
17538 * Makefile.am (MAKEINFO): Remove; it's a user-specified macro.
17540 (AM_MAKEINFOFLAGS): New macro.
17541 * doc/Makefile.am (MAKEINFO, AM_MAKEINFOFLAGS): Likewise.
17542 * Makefile.am (INSTALL): Use the new macros.
17543 Use -o rather than --output, since "missing" does not grok --output.
17545 2002-07-25 Alexandre Duret-Lutz <duret_g@epita.fr>
17547 * doc/autoconf.texi (Limitations of Make): Escaped newlines in
17548 comments do not always work. Never trust the exit status of
17551 2002-07-24 Kevin Ryde <user42@zip.com.au>
17553 * doc/autoconf.texi (Limitations of Make, Making testsuite Scripts):
17554 Untabify, since tabs are not enjoyed by texi2dvi and makeinfo.
17556 2002-07-23 Paul Eggert <eggert@twinsun.com>
17558 * lib/m4sugar/m4sh.m4 (_AS_PATH_SEPARATOR_PREPARE):
17559 Use PATH="/nonexistent;.", not PATH=".;.", as FreeBSD ksh2002
17560 apparently treats PATH="nonexistent" as if it contained ".".
17561 Bug reported by Stefan `Sec' Zehl.
17563 2002-07-22 Alexandre Duret-Lutz <duret_g@epita.fr>
17565 * doc/autoconf.texi (Limitations of Make): Mention the special
17566 handling of the obj/ directory by BSD make.
17568 2002-07-20 Kevin Ryde <user42@zip.com.au>
17570 * doc/autoconf.texi (Limitations of Make): Add HP-UX IA-64 trailing

17592 Handle LIBOBJS and LTLIBOBJS once for all, including Libtool's and

17599 2002-07-18 Akim Demaille <akim@epita.fr>,
17600 Alexandre Duret-Lutz <duret_g@epita.fr>
17602 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Install
17603 _AC_AM_CONFIG_HEADER_HOOK for Automake 1.7.

17831 This improves on an earlier suggestion by H. Peter Anvin.
17833 2002-05-16 Paul Eggert <eggert@twinsun.com>
17835 AC_FUNC_FNMATCH now tests only for POSIX compatibility.
17836 AC_FUNC_FNMATCH_GNU also tests for GNU extensions.
17837 Both macros now accept an optional source-dir arg.
17838 New macro AC_GNU_SOURCE to define _GNU_SOURCE.
17840 * NEWS: Document this.
17841 * doc/autoconf.texi (Particular Functions, UNIX Variants): Likewise.
17843 * lib/autoconf/functions.m4 (_AC_FUNC_FNMATCH): New macro.
17844 (AC_FUNC_FNMATCH): Use it. Test only for POSIX conformance,
17845 not for GNU extensions; this undoes part of the 2000-11-03 change,
17846 reverting to 2.13-compatible behavior.

17854 * lib/autoconf/headers.m4 (AC_HEADER_TIOCGWINSZ):
17855 Don't require AC_SYS_POSIX_TERMIOS. The test is unnecessary,
17856 and it causes a 'test' syntax error if it fails.
17857 Bug reported by Stephen Gildea.
17859 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
17860 If prototypes are supported, use them to check this at compile-time,
17861 instead of trying to check it at run-time. If we must do a run-time
17862 check, assume that setvbuf is standard when cross-compiling, as
17863 nonstandard setvbuf occurs only on ancient and unlikely hosts.
17864 Bug reported by Paul D. Smith.
17866 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Add optional
17867 argument specifying location of getloadavg.c. This removes a
17868 FIXME. This idea was taken from Jim Meyering's implementation in
17870 * doc/autoconf.texi (Particular Functions): Document this.
17871 Also, mention HAVE_NLIST_H rather than NLIST_STRUCT, since
17872 that's what the code does; this fixes a bug reported by

17877 * bin/autoreconf.in (autoreconf): Rewrite to use Gettext's
17878 autopoint instead of gettextize.
17879 ($uses_alocal): Rename as...
17880 ($uses_aclocal): this.
17881 * doc/autoconf.texi (autoreconf Invocation): Adjust.
17882 Suggested by Bruno Haible.
17884 2002-05-03 Akim Demaille <akim@epita.fr>
17886 * lib/m4sugar/m4sugar.m4 (m4_map_sep): New.
17888 2002-04-29 Paul Eggert <eggert@twinsun.com>
17890 * bin/autoreconf.in (autoreconf): Don't age aclocal.m4's input
17891 files to be 1 second older; just set them to be the same time.
17892 Also, sleep 1 second after the first aclocal, to work around
17893 problems with sub-second time stamps on the input files.
17895 2002-04-29 Thien-Thi Nguyen <ttn@gnu.org>
17897 * doc/autoconf.texi: Mention "set -e -x" lossage
17898 under node "Limitations of Builtins".

17904 From Christian Cornelssen.
17906 2002-04-29 Akim Demaille <akim@epita.fr>
17908 * tests/m4sh.at (LINENO): If testsuite itself is rewritten because
17909 of lack of $LINENO support, then the test will compare the $LINENO
17910 in testsuite vs. the lineno in the test file. This is wrong, of
17912 Be sure to protect it.
17913 Reported by Patrick Welche.
17915 2002-04-25 Akim Demaille <akim@epita.fr>
17917 * doc/autoconf.texi (Obsolete Macros): Typo.
17918 Reported by Vladimir Volovich.
17920 2002-04-25 Akim Demaille <akim@epita.fr>
17922 * bin/autoreconf.in (autoreconf): Don't let aclocal.m4 be older
17923 than some of the input files, hence, on the second run of aclocal,
17924 if some of its input are younger, make them older.
17925 Suggested by Paul Eggert.
17927 2002-04-25 Akim Demaille <akim@epita.fr>
17929 * doc/autoconf.texi (Limitations of Usual Tools): sed and `!'.

17934 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Let ac_subst_files
17935 and ac_subst_vars be sh variables containing the list of
17936 AC_SUBST_FILES'ed and AC_SUBST'ed identifiers. Output them in the
17938 (_AC_INIT_PREPARE): Use them to log them.
17939 (_AC_SUBST, _AC_SUBST_SED_PROGRAM): Remove.
17940 (AC_SUBST, AC_SUBST_FILE): Instead of buliding the
17941 _AC_SUBST_SED_PROGRAM, store the list of output files/variables in
17942 _AC_SUBST_FILES and _AC_SUBST_VARS.
17943 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Adjust.
17945 2002-04-24 Akim Demaille <akim@epita.fr>
17947 * bin/autoreconf.in (autoreconf): Run automake after autoconf and
17948 autoheader, so that automake does not complain about a missing
17949 config.h.in that was to be created.
17951 2002-04-23 Akim Demaille <akim@epita.fr>

18098 Reported by Ezra Peisach.
18100 2002-04-04 Andreas Schwab <schwab@suse.de>
18102 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Only simplify if path
18103 contains no literal separators.
18105 2002-04-03 Akim Demaille <akim@epita.fr>
18107 * lib/autoconf/status.m4 (_AC_CONFIG_FILE, _AC_CONFIG_HEADER)
18108 (_AC_CONFIG_COMMAND, _AC_CONFIG_LINK): New.
18109 Use dnl, not the KILL diversion.
18111 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_COMMANDS)
18112 (AC_CONFIG_LINKS): here.
18114 Don't use the KILL diversion, as it kills spurious output, which
18115 results in failures being hidden.
18116 Use m4_defn where appropriate.
18117 (AC_CONFIG_IF_MEMBER): Kill the real bug: a spurious parenthesis
18118 after the second argument.
18120 * lib/autom4te.in (Autoconf, Autotest, M4sh): Don't pass --warning
18121 syntax, as it is provided by M4sugar.

18138 (_AC_COMPILER_OBJEXT): Use them.
18139 Fixes Debian #138666.
18141 2002-04-02 Peter Eisentraut <peter_e@gmx.net>
18143 Integrate AC_PROG_CC_STDC into AC_PROG_CC.
18145 * lib/autoconf/c.m4 (AC_PROG_CC_STDC): Rename to _AC_PROG_CC_STDC.
18146 AU_DEFUN old name. Use _AC_COMPILE_IFELSE.
18147 (AC_PROG_CC): Call _AC_PROG_CC_STDC.

18149 (AC_C_CONST): Same.

18163 * lib/autoconf/c.m4 (AC_C_INLINE): Test with a typedef return value,
18164 to avoid versions of HP C which don't allow that.
18166 2002-03-27 Paul Eggert <eggert@twinsun.com>
18168 * lib/m4sugar/m4sh.m4 (_AS_BASENAME_PREPARE): New macro.

18180 2002-03-25 Paul Eggert <eggert@twinsun.com>
18182 * tests/m4sh.at: Don't rely on "PATH=test:$PATH test-1" working
18183 as POSIX requires, as it doesn't work with Zsh.
18184 * doc/autoconf.texi (Assignments): Document the problem.
18186 2002-03-25 Alexandre Duret-Lutz <duret_g@epita.fr>

18195 problem with here-document buffer boundaries.
18197 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Unset ENV and BASH_ENV
18198 when reinvoking the shell, to work around problems with installers
18199 who put strange things like "cd" commands in their environments.

18219 * lib/m4sugar/m4sugar.m4 (m4_define_default, m4_fst, m4_map): New.

18224 (Limitations of Usual Tools): Add mkdir section.
18226 * lib/m4sugar/m4sh.m4 (_AS_MKDIR_P_PREPARE): New macro.
18227 (AS_MKDIR_P): Require it. Use mkdir -p if available, falling
18228 back on AS_DIRNAME to compute prefixes otherwise; this is
18229 roughly what mkinstalldirs does. That way, we need not have
18230 our own filename disassembler. The old disassembler did not
18231 work with Solaris 8 dtksh, which is ksh Version M-12/28/93d.
18233 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP):
18234 Create at_test_all by a series of assignments,
18235 not by a single assignment of a long string. The latter causes ksh
18236 version 11/16/88g to silently misbehave on OpenServer 5.0.6a,
18237 presumably because of a buffer overrun.
18239 2002-03-14 Paul Eggert <eggert@twinsun.com>
18241 * lib/autotest/general.m4 (at_times_skip):
18242 Renamed from at_times. Now a boolean.
18243 ksh93 Version M-12/28/93d doesn't like 'x=times; $x'; it
18244 says 'times: not found'.

18248 * bin/autoreconf.in (&study_gettextize): New.
18249 (&autoreconf): Handle newest gettextize.

18273 2002-03-11 Andreas Schwab <schwab@suse.de>

18276 does not do it if --with-lispdir is given.

18289 * Makefile.am (AUTOMAKE_OPTIONS): 1.6.
18291 2002-03-08 Akim Demaille <akim@epita.fr>
18293 * bin/autom4te.in (&handle_m4): Do not foreach with `$_' as it
18294 aliases the actual variables, and modifications of the former
18297 2002-03-08 Akim Demaille <akim@epita.fr>
18299 * bin/autom4te.in (&handle_m4): Protect us from corrupted file
18300 because of C-c: have m4 output in tmp files, then mv them.

18323 * doc/autoconf.texi (AC_LIBOBJ vs. LIBOBJS): New.
18324 * lib/autoconf/general.m4 (AC_INIT): More informative error
18325 message for LIBOBJ.

18332 2002-03-04 Akim Demaille <akim@epita.fr>
18334 * doc/autoconf.texi (Transforming Names): Equality between target
18335 and host is irrelevant.
18336 (Specifying Names, Canonicalizing): Remove all references to the
18337 backward compatibility hooks. Rather, collect them all into...
18338 (Hosts and Cross-Compilation): this new section.
18339 * doc/install.texi (System Type): Ditto.
18340 * lib/autoconf/general.m4 (AC_CANONICAL_HOST): Explicitly state
18341 that `--host' implies cross-compilation.
18343 2002-03-04 Akim Demaille <akim@epita.fr>
18345 * doc/autoconf.texi (Evaluation Macros): New.
18346 * lib/m4sugar/m4sugar.m4 (m4_lquote): Remove, it is totally
18348 (_m4_foreach): Define the variant with immediate evaluation so
18349 that it contains exactly the items, not an expression which
18350 evaluation is the current item.
18351 (m4_re_string, m4_re_word): Don't over quote them.
18353 2002-03-04 Akim Demaille <akim@epita.fr>
18355 Instead of having stacking `shift's evaluated at the end, let
18356 `foreach' loops immediately evaluate them.
18358 * lib/m4sugar/m4sugar.m4 (m4_quote, m4_dquote): Use $@ rather than
18359 $*. This is the n-th time I change my mind, but hopefully this is
18362 (m4_text_wrap): Use m4_foreach, which is finally correct _and_
18364 (m4_foreach_quoted, m4_car_quoted, _m4_foreach_quoted): Remove, as
18365 it was only a hack for m4_text_wrap.
18366 (m4_car2): Remove, replaced by...
18368 (_m4_foreach): Adjust.
18369 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Adjust, and use
18370 m4_bpatsubst for clarification.

18421 Fix Autoconf PR/207:
18422 AC_PREFIX_PROGRAM fails with dashed program names
18424 * lib/autoconf/general.m4 (AC_PREFIX_PROGRAM): Just use a fresh

18486 optional are the sum of the previous files on the command line'.
18487 Also, pass `--reload-state=' on them, so...
18488 (handle_m4): don't.
18489 * lib/autom4te.in (Autotest, Autoconf): Rely on M4sh.
18490 (M4sh): Rely on M4sugar.
18491 (Autotest, M4sh, M4sugar): Use frozen files.

18517 2002-01-29 Akim Demaille <akim@epita.fr>
18519 * tests/torture.at (Configuring subdirectories): Use configure.in,

18521 Reported by Alexandre Duret-Lutz and Larry Schmitt.
18523 2002-01-28 Akim Demaille <akim@epita.fr>
18525 * doc/autoconf.texi (Writing testsuite.at): AT_CLEANUP no longer
18528 2002-01-28 Akim Demaille <akim@epita.fr>
18530 * lib/autotest/general.m4 (AT_INIT): Don't be ridiculous: adjust
18531 AUTOTEST_PATH *after* it was set.
18532 Don't put `.' in the PATH: the user should be precise and `./' if
18533 needed. In addition, given that the test suite does some `cd', if
18534 `.' is in the path, the `tested programs' sections will report
18535 programs found in the test suite's directory, while during the
18536 tests (performed in their own directory), these programs are no
18537 longer visible. In other words, the results is confusing and
18539 * tests/m4sh.at: Adjust: don't rely on `.' being in the PATH.

18602 2002-01-06 Akim Demaille <akim@epita.fr>
18604 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Don't create
18605 package.m4, since is really depends upon configure.ac, not
18607 * doc/autoconf.texi (testsuite Scripts): Adjust.
18608 * tests/Makefile.am (package.m4): New.
18609 EXTRA_DIST it since its a source.
18611 2002-01-06 Akim Demaille <akim@epita.fr>
18613 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Move the AC_SUBST
18614 of PACKAGE_NAME, PACKAGE_TARNAME, PACKAGE_VERSION, PACKAGE_STRING,
18615 and PACKAGE_BUGREPORT from here...
18616 (_AC_INIT_DEFAULTS): to here, since it is unrelated to the
18618 (_AC_INIT_PREPARE): AC_DEFINE these symbols.
18619 * lib/autotest/general.m4: Use AT_PACKAGE_*, not PACKAGE_*.
18620 (AT_INIT): No longer catch `^PACKAGE_(BUGREPORT|STRING)$'.
18621 * tests/tools.at (autoheader): Adjust.
18622 * tests/atspecific.m4 (AT_CHECK_DEFINES): Adjust.
18624 2002-01-06 Akim Demaille <akim@epita.fr>

18630 * doc/autoconf.texi (Output): Improved wording regarding use of
18634 2001-12-18 Kevin Ryde <user42@zip.com.au>
18636 * doc/autoconf.texi (Function Portability): Add notes on sscanf
18637 sometimes needing writable input.
18639 2001-12-17 Jim Meyering <meyering@lucent.com>
18641 * doc/autoconf.texi (New Macros): Tweak wording.
18643 2001-12-14 Akim Demaille <akim@epita.fr>
18645 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): We cleaning up the
18646 trailing files, don't apply `-rf' to files which might not be
18647 created by configure (core, core.*, and *.core), but just `rm -f'.
18648 Suggested by Jonathan Kamens.
18650 2001-12-14 Aaron M. Ucko <amu@alum.mit.edu>
18652 * lib/autoconf/general.m4: Avoid duplicates in `$ac_configure_args'.
18654 2001-12-14 Akim Demaille <akim@epita.fr>
18656 * Makefile.am (MAINTAINERCLEANFILES): Remove configure.
18658 2001-12-13 Peter Eisentraut <peter_e@gmx.net>
18660 * lib/autoconf/status.m4 (_AC_SRCPATHS): Rename buildpath to
18661 abs_builddir, top_buildpath to abs_top_builddir, srcpath to
18662 abs_srcdir, top_srcpath to abs_top_srcdir.
18663 (_AC_OUTPUT_FILES): Adjust.
18664 * NEWS, doc/autoconf.texi, lib/autoconf/autotest.m4,
18665 * tests/atspecific.m4, tests/autoreconf.in, tests/tools.at,
18666 * tests/wrappl.in, tests/wrapsh.in: Adjust.
18668 2001-12-12 Steven G. Johnson <stevenj@alum.mit.edu>
18670 * lib/autoconf/fortran.m4 (_AC_PROG_F77_V_OUTPUT): Fix failed
18671 C/Fortran linking on HP/UX, by extracting the Fortran library
18672 search path from the LPATH line in the $F77 -v output.
18674 2001-12-12 Kevin Ryde <user42@zip.com.au>
18676 * doc/autoconf.texi (File Descriptors): Use a clearer layout for the
18677 forbidden file descriptors table.
18679 2001-11-26 Akim Demaille <akim@epita.fr>
18681 * bin/autoscan.in (%c_keywords): Build it at top level.
18682 Map to 1 in order to simplify its uses.
18684 2001-11-26 Akim Demaille <akim@epita.fr>
18686 * bin/autoscan.in (&scan_c_file, &scan_sh_file, &scan_makefile):
18687 Remove $filepath, useless.
18688 (&scan_makefile): Don't remove the $(FOO), ${FOO} and @FOO@
18689 variables, they are really part of the tokens.
18690 Split the input line on spaces and then look for tokens.
18691 Now autoscan ceases to ask for AC_PROG_LEX for the package Bison
18692 because of `lex$U.$(OBJEXT)'.
18693 (&scan_files): Use "@list" instead of join.
18694 * doc/Makefile.am (CLEANFILES): Add *.fns.
18696 2001-11-26 Akim Demaille <akim@epita.fr>
18698 * tests/autoreconf.in, tests/autom4te.in, tests/autoupdate.in:
18699 Remove, replaced by...
18700 * tests/wrappl.in: Be common for all the Perl executables.
18701 In particular autoscan and autoheader want -I.
18702 * configure.ac: Adjust.
18703 * lib/autoscan/headers: errno.h is portable.
18705 2001-11-26 Akim Demaille <akim@epita.fr>
18707 * bin/autoscan.in (used): New.
18710 2001-11-26 Akim Demaille <akim@epita.fr>
18712 * bin/autoscan.in (&scan_c_file): Better parsing of CPP
18714 (&scan_sh_file): Remove a duplicate pattern.
18715 (&check_configure_ac): Use long options.
18716 * lib/autoscan/headers (alloca.h): Check with AC_FUNC_ALLOCA.
18718 2001-11-26 Akim Demaille <akim@epita.fr>
18720 * bin/autoscan.in (scan_c_file): Fix the handling of C comments.
18721 Before, having a line containing the opening of a multi line
18722 comment made the whole line be ignored.
18724 2001-11-26 Akim Demaille <akim@epita.fr>
18726 * doc/autoconf.texi (Using an Autotest Test Suite): New.
18727 (testsuite Scripts): Be one of its subsection.
18728 (Autotest Logs): New.
18730 2001-11-26 Akim Demaille <akim@epita.fr>
18732 Test groups are now run two directories deeper.
18734 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Replace srcdir,
18735 top_srcdir and top_builddir with at_srcdir, at_top_srcdir and
18737 * lib/autotest/general.m4 (AT_INIT): Compute srcdir,
18738 top_srcdir, builddir and top_builddir.
18739 Use `at_*dir' relatively to the directory containing the
18740 suite, use `*dir' when relatively to the current group dir.
18742 2001-11-25 Joseph S. Myers <jsm28@cam.ac.uk>
18744 * doc/autoconf.texi, TODO, lib/autoconf/fortran.m4,
18745 lib/autoconf/functions.m4, lib/autoconf/headers.m4,
18746 tests/atgeneral.m4, tests/tools.at, tests/atspecific.m4: Fix
18749 2001-11-22 Alexandre Duret-Lutz <duret_g@epita.fr>
18751 * doc/autoconf.texi (Using System Type): Add an example of `case
18752 $host' usage so people quit using `case $target' everywhere.
18754 2001-11-22 Akim Demaille <akim@epita.fr>
18756 * doc/autoconf.texi (Installation Directory Variables): Englishoes
18757 spotted by Jim Meyering.
18759 2001-11-16 Paul Eggert <eggert@twinsun.com>
18761 This patch implements a `long double' suggestion by Oliver Kiddle.
18763 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C)): Make the array
18764 static, to catch errors if the value isn't known at compile-time
18765 and the compiler supports dynamic arrays. Change its name from
18766 `_array_' to `test_array' to avoid potential name clashes.
18767 (AC_C_LONG_DOUBLE): Make it a compile-time test, not a run-time
18768 test. Do not define HAVE_LONG_DOUBLE if `long double' is no
18769 better than double. Catch a bug in GCC 2.95.2 x86.
18770 * doc/autoconf.texi (C Compiler): Document the above.
18773 2001-11-13 Akim Demaille <akim@epita.fr>
18775 * tests/m4sh.at (LINENO): Protect from autom4te's substitution by
18777 * tests/tools.at: Don't protect dnl, AT_DATA_M4SH does.
18779 2001-11-13 Akim Demaille <akim@epita.fr>
18781 * lib/autotest/general.m4 (AT_INIT): After having run the test
18782 group, go back to the initial directory, not to at_suite_dir.
18784 2001-11-13 Akim Demaille <akim@epita.fr>
18786 * tests/atspecific.m4 (AT_DATA_M4SUGAR, AT_DATA_M4SH)
18787 (AT_DATA_AUTOCONF): Also protect @&t@ from autom4te.
18788 (AT_CHECK_AUTOCONF, AT_CHECK_AUTOHEADER): Pass no --include
18790 (AT_CHECK_CONFIGURE): Use absolute paths.
18791 (_AT_CHECK_AC_MACRO): Create aclocal.m4 with AC_STATE_SAVE in it.
18792 The problem is still the old one: there is no means in M4 (that I
18793 know about) to create a defining macro, because there is no means
18794 to create `$1' etc., therefore, the defining macro ``swallows''
18795 all the arguments meant to the defined macro.
18797 2001-11-13 Akim Demaille <akim@epita.fr>
18799 * tests/atspecific.m4 (AT_DATA_AUTOCONF): New.
18800 (AT_CONFIGURE_AC): Output the definition of AC_STATE_SAVE in
18802 * tests/aclocal.m4: Remove, as it is no longer used.
18804 2001-11-13 Akim Demaille <akim@epita.fr>
18806 * lib/autotest/general.m4: Change `tests?' into `groups?' in
18807 variable names when referring to a single test group, or to
18808 `suite' when referring to the whole test suite.
18809 `at_last_test' is removed: m4 compute at_format itself.
18810 (at_stdout, at_stder1, at_stderr): New variables.
18811 (AT_CHECK): Use them.
18813 2001-11-13 Akim Demaille <akim@epita.fr>
18815 * lib/autotest/general.m4 (AT_INIT): Be sure to put `.', relative,
18817 Create `testsuite.dir/003/run' instead of `testsuite.003'.
18818 Do it as soon as a test fails, don't wait till the end of the test
18820 Don't remove $as_me.[0-9]*, since these files no longer exist.
18822 2001-11-13 Akim Demaille <akim@epita.fr>
18824 * tests/tools.at: Use absolute paths, since we are no longer run
18827 2001-11-13 Akim Demaille <akim@epita.fr>
18829 Now that tests are running in their own private dir, there is no
18830 need to list the files to remove at the end of tests groups.
18832 * lib/autotest/general.m4 (_AT_CLEANUP_FILE, AT_CLEANUP_FILES):
18833 (AT_data_files, at_data_files): Remove.
18834 (AT_CLEANUP, AT_DATA): Simplify.
18836 Remove the group dir if !debug && !failed.
18837 * tests/atspecific.m4: Adjust.
18839 2001-11-13 Akim Demaille <akim@epita.fr>
18841 Start a new layout for Autotest: `testsuite' creates
18842 `testsuite.dir' in which the at-check-line etc. files are to be
18843 found, and `testsuite.dir/003' where the test group 3 is run.
18845 * lib/autotest/general.m4 (AT_INIT): at_tests_dir,
18846 at_check_line_file, at_format, at_test_normalized, at_group_dir
18848 Create the directories.
18849 Use absolute paths for at- files.
18850 (AT_CHECK): Adjust.
18852 2001-11-11 Michael Matz <matz@kde.org>
18854 * m4sugar.m4 (_m4_foreach): Make it linear instead quadratic.
18856 (m4_car): Properly quote arguments.
18858 2001-11-13 Akim Demaille <akim@epita.fr>
18860 * tests/aclocal.m4 (AC_STATE_SAVE): s/LIBOBJS/LIB@&t@OBJS/ to cope
18861 with stricter rules on LIBOBJS.
18863 2001-11-12 Paul Eggert <eggert@twinsun.com>
18865 * lib/autoconf/c.m4 (AC_C_PROTOTYPES): Define __PROTOTYPES too.
18866 * doc/autoconf.texi (C Compiler): AC_C_PROTOTYPES now defines
18869 2001-11-12 Akim Demaille <akim@epita.fr>
18871 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT): Use AC_CHECK_FUNCS.
18873 2001-11-12 Akim Demaille <akim@epita.fr>
18875 * lib/autoconf/c.m4, lib/autoconf/fortran.m4,
18876 * lib/autoconf/functions.m4, lib/autoconf/general.m4,
18877 * lib/autoconf/headers.m4, lib/autoconf/libs.m4,
18878 * lib/autoconf/programs.m4, lib/autoconf/specific.m4,
18879 * lib/autoconf/types.m4: When invoking AC_DEFINE and friends,
18880 specify to what the macro should be defined (typically to 1).
18882 2001-11-12 Akim Demaille <akim@epita.fr>
18884 * lib/autoconf/functions.m4 (AC_FUNC_STRTOD): AC_SUBST POW_LIB.
18887 2001-11-12 Akim Demaille <akim@epita.fr>
18889 * lib/autoconf/programs.m4 (_AC_PROG_LEX_YYTEXT_DECL): Use
18890 AC_TRY_EVAL to run $LEX, not AC_TRY_COMMAND. This validates the
18891 definition used by Automake where LEX is +/- "${missing} lex" and
18892 `missing' itself contains variables.
18894 2001-11-12 Akim Demaille <akim@epita.fr>
18896 * lib/autotest/general.m4 (AT_INIT): Push KILL at the end.
18897 Now that M4sh pushes BODY, the comments were output at the end of
18900 2001-11-08 Akim Demaille <akim@epita.fr>
18902 * bin/autoreconf.in (&autoreconf): Run aclocal before tracing, so
18903 that we can trace macros from aclocal.m4.
18904 Trace AC_PROG_LIBTOOL, not AM_PROG_LIBTOOL, since the latter is
18905 obsoleted, and redirect to the former anyway.
18906 Reported by Ralf Corsepius.
18908 2001-11-08 Akim Demaille <akim@epita.fr>
18910 * bin/autoreconf.in (&autoreconf): AC_CONFIG_SUBIDRS are to be
18911 processed only if present.
18912 * tests/torture.at (Configuring subdirectories): Use autoreconf
18913 instead of successive calls to autoconf.
18914 Add a nonexistent subdirectory to exercise the patch above.
18915 Reported by Ralf Corsepius.
18917 2001-11-08 Kevin Ryde <user42@zip.com.au>
18919 * doc/autoconf.texi (Limitations of Usual Tools): Note HP-UX cc
18920 doesn't accept .S files.
18922 2001-11-07 Akim Demaille <akim@epita.fr>
18924 * lib/m4sugar/m4sugar.m4 (m4_pattern_forbid): Accepts $2.
18925 * lib/autoconf/general.m4 (AC_INTI): Forbid LIBOBJS.
18926 (_AC_LIBOBJ): s/LIBOBJS/LIB@&t@OBJS/.
18927 * bin/autom4te.in (warn_forbidden): New.
18928 (handle_output): Use it.
18929 Read m4_pattern_forbid with messages.
18931 2001-11-05 Akim Demaille <akim@epita.fr>
18933 * bin/autom4te.in (--normalize): Remove.
18934 * lib/autom4te.in: Adjust.
18936 2001-11-05 Akim Demaille <akim@epita.fr>
18938 * tests/Makefile.am (testsuite): Rename this target as...
18939 ($(TESTSUITE)): this.
18942 2001-11-05 Alexandre Duret-Lutz <duret_g@epita.fr>
18944 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): When removing
18945 the --prefix option, also remove it's argument.
18947 2001-11-05 Akim Demaille <akim@epita.fr>
18949 * doc/autoconf.texi (testsuite Invocation): Update.
18950 (Writing testsuite.at): Update.
18952 2001-11-03 Akim Demaille <akim@epita.fr>
18954 * doc/autoconf.texi: s/@code/@command/ where appropriate.
18956 2001-11-03 Akim Demaille <akim@epita.fr>
18958 * lib/Autom4te/General.pm: (&catfile, &canonfile)
18959 (&file_name_is_absolute): New, wrappers around routines from
18961 Use and export them.
18962 (&find_configure_ac): Optionally take a directory where to look at.
18963 * bin/autoreconf.in (&parse_args): Trim the configure.ac part of
18965 Default @ARGV to `.', not find_configure_ac.
18966 (&autoreconf): Argument is a directory.
18967 Trace AC_CONFIG_SUBDIRS and schedule the subdirs for autoreconf'ing.
18968 * doc/autoconf.texi (autoreconf Invocation): Update.
18970 2001-11-03 Akim Demaille <akim@epita.fr>
18972 * lib/Autom4te/General.pm (@export_vars, @export_subs)
18973 (@export_forward_subs): New.
18974 Add basename, dirname, and fileparse.
18976 * bin/autoreconf.in (&autoreconf): Fix call to fileparse.
18977 Don't look for aclocal flags if we already know aclocal is not
18979 Move aclocal.m4t only if it exists.
18980 Reported by Ezra Peisach.
18982 2001-11-03 Akim Demaille <akim@epita.fr>
18984 * bin/autoreconf.in (&parse_args): Work only on the configure.ac
18985 passed on command line, defaulting to ./configure.ac if present.
18986 (&maybe_autoreconf, File::Find): Remove, unused.
18987 (&autoreconf): If autoconf is not used, don't try to trace.
18989 2001-11-02 Akim Demaille <akim@epita.fr>
18991 * configure.ac: Bump to 2.52g.
18993 2001-11-02 Akim Demaille <akim@epita.fr>
18997 2001-11-02 Akim Demaille <akim@epita.fr>
18999 * config/config.guess, config/config.sub, doc/standards.texi:
19000 * config/lispdir.m4: Update from masters.
19001 * configure.ac: Bump to 2.52f.
19003 2001-11-02 Akim Demaille <akim@epita.fr>
19005 * bin/autoreconf.in (&autoreconf): Set `$aclocal_flags' to ''.
19006 Don't run aclocal when aclocal.m4 is not from aclocal.
19008 Don't run libtoolize and gettextize if --install is not given.
19010 2001-11-01 Paul Eggert <eggert@twinsun.com>
19012 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): _AS_CR_PREPARE needs to
19013 be invoked before _AS_LINENO_PREPARE.
19014 (_AS_LINENO_PREPARE): Use as_cr_digits and as_cr_alnum rather
19015 than character ranges.
19017 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Fix NLS before
19018 invoking AS_BASENAME. Set the locale variables to 'C' if
19019 possible, as POSIX requires this to get the traditional
19021 * doc/autoconf.texi (Special Shell Variables): Describe the above.
19023 2001-10-31 Paul Eggert <eggert@twinsun.com>
19025 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): Do not surround body
19026 with {}, as that triggers a bug in Bash 2.05.
19028 (_AS_LINENO_PREPARE): Use Sed rather than
19029 Awk. Fix the sed prepass to work even if there are multiple
19030 instances of $LINENO on the same line. Do not substitute for
19031 other variables like $LINENOT. Do not check file dates; such a
19032 check is unreliable on sufficiently fast machines, and removing
19033 the check makes the code simpler and more reliable. Check for
19034 output and chmod failures.
19036 * doc/autoconf.texi (Special Shell Variables): Document
19039 2001-10-31 Akim Demaille <akim@epita.fr>
19041 * tests/Makefile.am (atconfig): Remove this target, Automake
19044 2001-10-31 Akim Demaille <akim@epita.fr>
19046 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Do not
19047 AC_CONFIG_FILES(atlocal) as it means a file atlocal.in *must* be
19048 provided, while it is optional.
19049 * configure.ac: Adjust.
19051 2001-10-26 Paul Eggert <eggert@twinsun.com>
19053 * NEWS, README, configure.ac, lib/Autom4te/General.pm,
19054 lib/Autom4te/Struct.pm:
19055 Require Perl 5.005_03 instead of just 5.005, as some tests fail
19058 * doc/autoconf.texi (Special Shell Variables): Document some
19059 more LINENO gotchas, particularly with respect to the Awk+Sed hack.
19061 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): New macro.
19062 (_AS_LINENO_PREPARE): Use it instead of shell eval, since
19063 eval $LINENO is not portable in practice.
19065 2001-10-24 Akim Demaille <akim@epita.fr>
19067 * lib/Autom4te/General.pm (backname): New.
19069 2001-10-24 Akim Demaille <akim@epita.fr>
19071 * m4/: Remove, merged into...
19074 2001-10-23 Tim Van Holder <tim.van.holder@pandora.be>
19076 * doc/autoconf.texi (Shellology): Mention the problems with bash
19077 2.05's use of ANSI quoting in its `set' builtin.
19079 2001-10-22 Paul Eggert <eggert@twinsun.com>
19081 * lib/autoconf/functions.m4 (AC_FUNC_STRERROR_R):
19082 Rename ac_cv_func_strerror_r_works to ac_cv_func_strerror_r_char_p,
19083 and rename HAVE_WORKING_STRERROR_R to STRERROR_R_CHAR_P, since
19084 POSIX decided to standardize on the int flavor of strerror_r.
19085 Always do char* test, as there's no reason not to.

19583 be used instead of ':'.
19584 * lib/autotest/general.m4: Replace occurrences of ':' in
19585 AUTOTEST_PATH with $PATH_SEPARATOR at test suite startup.
19587 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>

19590 arguments. Fixed a typo.
19592 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
19594 * man/Makefile.am (.x.1): Use @PATH_SEPARATOR@, not ':' to set up
19595 $PATH. Also set AUTOM4TE_CFG, so we can process autom4te properly.
19597 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
19599 * bin/autoscan.in: Add 'exec-perl-if-not-run-by-perl'.

19608 * lib/Autom4te/XFile.pm (open): Simplified the error message (we
19609 already have $file). Set output files to binary mode (helps avoid
19610 CR issues on DOSish systems).
19612 2001-09-19 Akim Demaille <akim@epita.fr>
19614 * lib/autotest/general.m4: Englishoes.
19615 From Tim Van Holder and Alexey Mahotkin.
19617 2001-09-18 Paul Eggert <eggert@twinsun.com>
19619 * doc/autoconf.texi (Common Shell Constructs): New node,
19620 documenting AS_DIRNAME.
19621 (Limitations of Usual Tools): Refer to it when discussing dirname.
19622 Also, update discussion of POSIX standard to reflect latest draft.
19624 * lib/autoconf/c.m4:
19625 (AC_LANG_INT_SAVE(C)): Also support negative values, down to LONG_MIN.
19627 * lib/autoconf/general.m4 (_AC_COMPUTE_INT_COMPILE):
19628 Do not pass a first argument with leading '-'
19629 to expr, by parenthesizing initial integers that might be negative.
19631 * doc/autoconf.texi (Particular Functions): AC_FUNC_GETPGRP
19632 now merely checks whether it is an error to pass an argument
19635 * lib/autoconf/functions.m4 (_AC_FUNC_GETPGRP_TEST): Remove.
19636 (AC_FUNC_GETPGRP): Don't bother with a runtime test. Just check
19637 whether it is a (compile-time) error to pass an argument to
19638 getpgrp. This simpler test supports the revised documentation,
19639 and is all that AC_FUNC_GETPGRP's users really need.
19641 2001-09-18 Akim Demaille <akim@epita.fr>
19643 * doc/autoconf.texi (Limitations of Make) <$<>: New.

19653 * tests/m4sh.at: Ensure that AS_DIRNAME handles '/', '//' and '///'
19655 Add test for AS_BASENAME.
19656 * lib/m4sugar/m4sh.m4: Fix AS_BASENAME so that it passes the previous
19657 added test. It now correctly handles /1/2/3/, returning '3' not ''.
19658 Added AS_BASENAME_SED to make the interface the same as AS_DIRNAME.
19659 * tests/base.at: Fixed the expected responses. The old ones were
19661 * lib/autoconf/general.m4: Fixed AC_PREFIX_PROGRAM, it now behaves as
19662 the documentation claims it should (and how it behaved in 2.13).
19664 2001-09-18 Akim Demaille <akim@epita.fr>
19666 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): No INIT-CMDS in
19667 the AC_CONFIG_COMMANDS invocation.
19668 This also solves the name clash problems.
19669 Don't set the package's ID.
19670 * lib/m4sugar/Makefile.am (version.m4): Revamp.
19671 No longer to be shipped.
19672 (version.in): Remove.
19673 * lib/m4sugar/m4sugar.m4, lib/autoconf/general.m4,
19674 * lib/autoconf/status.m4: Adjust.
19675 Use `m4_PACKAGE_STRING'.
19676 * lib/autotest/general.m4 (AT_INIT): N-th signature change: now
19677 the only optional argument is the name of the test suite.
19678 Expect `package.m4' to define the package signature.
19679 * lib/autom4te.in (Autotest): Add `package.m4?'.
19680 * tests/Makefile.am (package.m4): New.
19681 * tests/suite.at: ifnames is a victim.
19683 2001-09-18 Akim Demaille <akim@epita.fr>
19685 * lib/autom4te.in (Autoconf): Preselect AM_CONDITIONAL,
19686 AC_LIBSOURCE, AC_CONFIG_FILES.
19687 * lib/autotest/general.m4 (AT_INIT): Don't abort when a tested
19688 program version string doesn't match the package's.
19689 * lib/autoconf/general.m4 (AC_CACHE_VAL): Reestablish the space

19700 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):
19701 Always include <stdio.h> and <stdlib.h>. Evaluate
19702 the expression in an extra function before these includes. Call
19703 fprintf "%d" only after ensuring the argument is of type 'int'.
19704 Reported by Wayne Chapeskie <waynec@spinnaker.com>.
19706 2001-09-17 Paul Eggert <eggert@twinsun.com>
19708 Fix bug reported by Paul Townsend on AIX 4.3.3.0 with CFLAGS=-O4
19709 or CFLAGS=-O5. In that case, the linker has a relaxed view of
19710 fatal errors, and AC_CHECK_LIB causes it to include libraries even
19711 when they don't exist.
19713 * lib/autoconf/headers.m4 (AC_HEADER_DIRENT): Use AC_SEARCH_LIBS,
19714 not AC_CHECK_LIB, so that we don't use -ldir or -lx if we don't
19717 * lib/autoconf/specific.m4 (AC_ISC_POSIX): Replace the old, crufty
19718 version with the version used by fileutils 4.1, except use
19719 AC_SEARCH_LIBS, not AC_CHECK_LIB, so that we don't use -lcposix if
19722 * doc/autoconf.texi (AC_ISC_POSIX): Describe new behavior.
19724 2001-09-13 Akim Demaille <akim@epita.fr>

19764 * lib/autotest/general.m4 (AT_INIT): Create and remove
19765 `$as_me.[0-9]+' instead of `debug-[0-9]+.sh', so that multiple
19766 test suites can cohabit.
19768 2001-09-13 Akim Demaille <akim@epita.fr>
19770 * tests/mktests.sh: Don't output banners for empty test files.

19876 2001-09-05 Akim Demaille <akim@epita.fr>

19879 the maintainer is dumb enough to do that...
19881 * lib/autotest/general.m4 (AT_SETUP, AT_LINE): Demonstrates your
19882 excellence in M4 quotation: consider `__file__' is active.
19884 And BTW, when invoking m4, pass the --include in the right order:

19970 * lib/autotest/general.m4 (AT_INIT): Don't pass all the args to

20032 * bin/autoconf.in (--include, -I): New option.
20033 Map --localdir, --autoconf-dir onto it.
20034 Forward autom4te's options instead of interpreting them.
20035 * bin/autoconf.in, bin/autoheader.in (AC_MACRODIR, autoconf_dir):
20036 There is no such envvar since the inception of autom4te.cfg.
20037 * bin/autom4te.in (&parse_args): Uniquify `@include'.
20038 * bin/autoupdate.in: Adjust, and perform more control.
20039 * tests/atspecific.m4 (AT_CHECK_AUTOCONF): Adjust.
20040 * tests/autoconf: Dittowise.
20042 2001-08-31 Akim Demaille <akim@epita.fr>
20044 * bin/autoconf.in: Don't bother with `acsite.m4' and `aclocal.m4'.
20045 * bin/autom4te.in (&find_file): Support `FILE?' standing for
20047 Use -e, not -f, since /dev/null for instance is OK.
20048 (&parse_args): Adjust.
20049 * lib/autom4te.in (Autoconf): Add `acsite.m4?' and `aclocal.m4?'.

20058 * lib/Autom4te/General.pm (&find_peer): Remove.
20059 * lib/autotest/general.m4 (AT_INIT): `AUTOTEST_PATH=a:b' gives

20061 * man/Makefile.am: Let help2man rely on PATH instead of trying to
20062 find the executables for it.

20064 * tests/atlocal.in: Remove all the obscure envvar manipulations.
20066 * tests/atspecific.m4, tests/tools.at: Passing --localdir is
20067 indeed related to running the test suite, while passing
20068 --autoconf-dir and others is related to running non installed
20069 Autoconf executables. So don't do that, leave it to...

20071 * tests/autoscan: New.
20072 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): Don't

20089 Suggested by Paul Eggert.
20091 2001-08-29 Akim Demaille <akim@epita.fr>
20093 * Makefile.maint (do-po-update): Wget refuses to overwrite files:
20094 download in a tmp dir.
20096 2001-08-29 Akim Demaille <akim@epita.fr>

20480 * lib/autotest/general.m4 (AT_INIT): Refer to `$as_me.log', not

20498 * doc/autoconf.texi: Work around Texinfo buglets.
20499 (Transformation Rules): One example is enough, users are expected

20558 autom4te.cache (it's a directory, not a file.
20559 * Makefile.am: Ditto (but maintainer-clean-local).
20561 2001-08-15 Akim Demaille <akim@epita.fr>
20563 * bin/autom4te.in (@m4_warning): New.
20564 (&handle_m4): Use it.
20565 * tests/m4sugar.at (m4_warn): Pass `-f' to autom4te to ensure the
20566 warnings are issued at each run.
20567 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): M4sugar
20568 is in the src tree.
20570 2001-08-15 Akim Demaille <akim@epita.fr>
20572 * tests/atspecific.m4 (AT_CHECK_AUTOUPDATE): Perl is now required:
20573 don't waste time running `autoupdate --version' works.

20642 2001-08-11 Alexandre Duret-Lutz <duret_g@epita.fr>
20644 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Guess endianness by grep'ing
20645 magic values from an object file when cross-compiling.
20646 Based on code by Guido Draheim <Guido.Draheim@gmx.de>.
20648 2001-08-10 Akim Demaille <akim@epita.fr>
20650 * bin/autom4te.in (&handle_output): Don't use `grep' with side
20652 Suggested by Russ Allbery.
20654 2001-08-10 Ralf Corsepius <corsepiu@faw.uni-ulm.de>
20656 * lib/autoconf/general.m4 (_AC_OUTPUT_SUBDIRS): Propagate the
20657 current $prefix to the sub-configures.
20659 2001-08-09 Tim Van Holder <tim.van.holder@pandora.be>
20661 * lib/autoconf/lang.m4: Ignore *.xSYM when looking for an executable
20662 extension (needed on BeOS). Reported by Guido van Rossum.
20664 2001-08-09 Akim Demaille <akim@epita.fr>
20666 * bin/autom4te.in ($icache): Load it only if older than autom4te.
20668 2001-08-07 Akim Demaille <akim@epita.fr>
20670 * lib/autotest/general.m4 (AT_INIT): All the `at-*' are to be
20672 (at-setup-line): Huh? Be a variable `at_setup_line', not a file.
20673 No need to remove the files before and after the each test, before
20674 each test and at the end of the suite is enough.
20675 Display only the children `times', not the shell's.
20676 If the test failed or was skipped, at-times is not available.
20678 2001-08-07 Akim Demaille <akim@epita.fr>
20680 Always produce testsuite.log, including when there are no
20681 failures. This helps getting information on skipped tests, and
20682 duration of the tests. Err, implement the latter btw.
20684 * lib/autotest/general.m4 (AT_INIT): Set up fd 6 for the log.
20685 Dump information on the first run of each test.
20686 (AT_CLEANUP): Create `at-times' containing the duration of the
20689 2001-08-07 Akim Demaille <akim@epita.fr>
20691 The use of `dumpstat' revealed that `len' was used although it
20692 should not. m4_text_wrap was using it, but in the Autoconf world
20693 where it is legal. Hence (i) test M4sh in its own world, not
20694 Autoconf's, and (ii), ahem, fix the bug :)
20696 * lib/autotest/general.m4: Be sure the set good quotes, as tracing
20697 does not like `' instead of [].
20698 (AT_INIT): Forbid `^_?AT_'.
20699 And don't output such tokens.
20700 * tests/Makefile.am (CLEANFILES): Add `script', `script.s4g',
20701 `script.as', and `autom4te.cache'.
20702 Remove `empty' and `macro' which are no longer used.
20703 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): New.
20704 * tests/m4sugar.at: Use it.
20705 * lib/m4sugar/m4sugar.m4: Use `m4_len' not `len'.
20707 2001-08-07 Akim Demaille <akim@epita.fr>
20709 * bin/autoconf.in, bin/autoheader.in: --force, -f is a new option.
20711 2001-08-07 Alexandre Duret-Lutz <duret_g@epita.fr>
20713 * bin/autom4te.in (handle_output): Typo in quadrigraph substitution.
20715 2001-08-04 Akim Demaille <akim@epita.fr>
20717 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA, AC_FUNC_ERROR_AT_LINE)
20718 (AC_FUNC_FSEEKO, AC_FUNC_OBSTACK): Use AC_LANG_IFELSE, not
20720 * lib/autoconf/headers.m4 (AC_HEADER_MAJOR): Likewise.
20721 * lib/autoconf/fortran.m4 (_AC_LANG_PROGRAM_C_F77_HOOKS)
20722 (AC_F77_MAIN): Likewise.
20724 2001-08-04 Akim Demaille <akim@epita.fr>
20726 Don't rely on M4sugar outputting the patterns in files, since we
20727 might process the output _without_ running m4, hence without these
20730 * lib/m4sugar/m4sugar.m4 (m4_init): No need for `m4_tmpdir'.
20731 * bin/autom4te.in (@Request::includes): Remove, unused.
20732 (@Request::source): Rename as...
20733 (@Request::input): this.
20734 (@preselect): Add `m4_pattern_forbid' and `m4_pattern_allow'.
20735 (&handle_output): Fetch the patterns from the traces.
20736 `$forbidden' and `$allowed' are constant: use m//o.
20737 (&handle_m4): M4sugar no longer wants `m4_tmpdir'.
20738 (m4_pattern_forbid, m4_pattern_allow): Adjust for tracing only.
20740 2001-08-04 Akim Demaille <akim@epita.fr>
20742 `autoconf && autoheader' is sped up. Now, speed up `autoheader &&
20743 autoconf', i.e., in addition to caching traces, cache the output.
20745 * bin/autom4te.in (Request::cache): Rename as...
20746 (Request::id): this.
20747 ($cache, $icache, $tcache, $ocache): New.
20748 (&handle_m4): Save M4 output in the cache instead of $tmp.
20749 (&handle_output): Adjust.
20750 (&up_to_date_p): Check that the output cache is up to date too.
20751 (top level): Run `&handle_m4' iff force or the cache is invalid.
20752 Run `&handle_output' if the output cache is more recent.
20754 2001-08-04 Akim Demaille <akim@epita.fr>
20756 * bin/autom4te.in ($force): New.
20757 (&parse_args, &print_usage): -f, --force is a new option.
20758 (&handle_output): CPP directives might have spaces after `#'.
20759 (&parse_args): The first file only can be frozen.
20761 2001-08-04 Akim Demaille <akim@epita.fr>
20763 Don't let autom4te compute the `include' traces several times:
20764 first check that the trace cache file is up to date, and then
20765 compare its timestamp with that of the output.
20767 * bin/autom4te.in, bin/autoupdate.in, bin/autoscan.in: Normalize
20768 the preamble. Don't require 5.005 as Autom4te::General does it,
20769 and better yet (use `use', not `require'!).
20770 * lib/Autom4te/Struct.pm: Rename the last occurrences of
20771 Class::Struct as Autom4te::Struct.
20772 * lib/Autom4te/General.pm (File::stat): Use it.
20773 (&mtime): New, export it.
20774 * bin/autom4te.in: Use it.
20775 Declare `$req' is invalid if it is outdated.
20776 Don't declare it valid before saving it if something went wrong.
20778 2001-08-04 Akim Demaille <akim@epita.fr>
20780 Autom4te shall not encode Autoconf data, and preselecting traces
20781 must be proposed to the users.
20783 * bin/autom4te.in (@required_trace): Remove.
20785 (&parse_args, &print_usage): -p, --preselect is a new option.
20786 (&up_to_date_p): Adjust.
20787 * bin/autoconf.in: Preselect some Autoconf macros.
20789 2001-08-04 Akim Demaille <akim@epita.fr>
20791 * tests/tools.at (autoconf --trace: user macros): Check traces on
20792 macros invoked without arguments, and macros invoked with multiple

20797 * bin/autom4te.in (handle_traces): Fix rewriting of traces without
20800 2001-08-03 Akim Demaille <akim@epita.fr>
20802 * bin/autoconf.in ($@): Work around the usual sh bug.
20805 2001-08-03 Akim Demaille <akim@epita.fr>
20807 Clean up the handling of the M4 builtins tracing exception.
20809 * bin/autom4te.in (Request::request): Don't complete M4 builtins
20811 (@m4_builtins): Rename as...
20812 (@m4_builtin): this.
20813 (%m4_builtin_alternate_name): New.
20814 (&parse_args): Complete the trace requests with alternate names.
20815 (&handle_traces): Hence no longer do it here.
20816 (&trace_requests): Remove, unused.
20818 2001-08-03 Akim Demaille <akim@epita.fr>
20820 * doc/autoconf.texi (Redefined M4 Macros): Document m4_exit,
20821 m4_if, and m4_wrap.
20823 2001-08-03 Akim Demaille <akim@epita.fr>
20825 * lib/m4sugar/m4sugar.m4 (m4_init): Also forbid `_m4_*' tokens.
20826 (m4_divert_pop): Dump the whole diversion stack when a diversion
20828 * bin/autom4te.in (&handle_output): Remember of the first
20829 occurrence of a possibly undefined macro, not the last.
20830 Complain about the possibly undefined macros in the same order as
20831 the appear in the output.
20832 * lib/autoconf/Makefile.am (autoconf.m4f): List its dependencies.
20833 * tests/tools.at (autoconf: forbidden tokens, basic)
20834 (autoconf: forbidden tokens, exceptions): No longer sort
20835 autoconf's stderr, as it is now deterministic.
20836 Check that `dnl' is caught.
20838 2001-08-01 Akim Demaille <akim@epita.fr>
20840 * configure.ac: Bump to 2.52c.

20852 2001-08-01 Akim Demaille <akim@epita.fr>

20857 * bin/autoconf.in, bin/autom4te.in, bin/autoupdate.in: Remove your
20858 `END', as `Autom4te::General::END' will be triggered.
20859 * bin/autoupdate.in, bin/autoscan.in: Improve error messages accuracy.
20860 * bin/autoupdate.in (File::Compare, File::Copy): Use them instead of
20861 system to run `mv', `rm', and `cmp'.

20865 * lib/Autom4te/General.pm (&unique): New.
