619 Work around DJGPP shell function return bug with command substitutions.
620 DJGPP bash 2.04 has a bug in that `return $ac_retval' done in a
621 shell function which also contains a command substitution causes
622 the shell to barf. For more details and a fix see:
623 <http://www.delorie.com/djgpp/mail-archives/browse.cgi?p=djgpp-workers/2009/09/09/03:35:08>
624 Possible workaround include putting the `return' in a subshell

652 DJGPP fix: remove both conftest and conftest.exe.
653 The DJGPP compiler may create both `a.out' and `a.exe' without -o,
654 and both `conftest' and `conftest.exe' with `-o conftest', but not
655 with `-o conftest.exe'.
656 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_O): Also remove
657 `conftest' without $ac_exeext suffix.

660 * lib/autoconf/general.m4 (AC_SITE_LOAD, AC_CACHE_LOAD): Do not
661 load the cache or site file if it is `/dev/null', as DJGPP treats
662 it as a regular file, but the shell then warns about it later.

5492 Don't infloop upon "make dist".
5493 * GNUmakefile: Merge from coreutils.
5494 * Makefile.am (dist-hook): Inject .tarball-version into tarball,
5496 * configure.ac (AC_INIT): Use .tarball-version, not .version.

5519 Cover more potentially problemtic file names. Use the new
5522 Properly handle funny file names for headers in config.status.
5523 The test suite did not cover this bug because the code was not
5524 quoting properly the arguments of `rm -f' (which "fails" silently)
5525 as well as the arguments of `diff' (whose output was redirected to
5526 /dev/null so we couldn't see its error message).
5527 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Properly quote the
5528 file names passed to `rm' and `diff'.
5529 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):

5638 forks when sanitizing PATH. Always output machine information,
5639 not just when atconfig was located.
5641 Add 'testsuite -C dir'.
5642 * lib/autotest/general.m4 (_AT_ARG_OPTION): Move missing argument
5644 (AT_INIT) <PARSE_ARGS_END>: ...here, since -k always takes
5646 <DEFAULTS>: Delay computation of variables based on $at_dir...
5647 <PREPARE_TESTS>: ...to here, since -C can change $at_dir.
5648 <TESTS>: Re-invoke via absolute name, since -C may be in effect.
5649 <PARSE_ARGS>: Parse new option.
5650 <HELP_TUNING>: Document it.
5651 * tests/autotest.at (Choosing where testsuite is run): New test
5653 (Keywords and ranges): Add test for missing -k argument.
5654 * NEWS: Document this.
5655 * doc/autoconf.texi (testsuite Invocation): Likewise.
5657 2008-01-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5659 * build-aux/config.guess, build-aux/config.sub,
5660 build-aux/texinfo.tex: Sync from gnulib.
5661 * doc/fdl.texi, doc/make-stds.texi, doc/standards.texi:
5664 2008-01-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5666 * doc/autoconf.texi (Particular Programs): Do not mention the
5667 Autoconf version in which the AC_PROG_INSTALL change was done.
5668 Suggested by Paul Eggert.
5670 2008-01-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5672 Fix --help=recursive with multiple AC_CONFIG_SUBDIRS.
5673 * lib/autoconf/general.m4 (_AC_INIT_HELP): If, for recursive help
5674 mode, we change to the source directory, also set $ac_pwd so we
5675 do not go back to the build tree for the next config subdir.
5676 * tests/torture.at (Deep Package): Extend test to contain two
5677 config subdirs on the top level.
5679 Fix parallel `maintainer-check'.
5680 * Makefile.am (maintainer-check-tests): Depend on `all'.
5681 Use `$(MAKE) $(AM_MAKEFLAGS)' instead of plain `make'.
5682 * tests/Makefile.am (maintainer-check-c++, maintainer-check-posix):
5684 (maintainer-check): Serialize the testsuite runs.

5708 2008-01-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5710 * tests/Makefile.am (noinst_SCRIPTS): Renamed from
5711 check_SCRIPTS. Building the wrappers for `all' allows help2man
5712 to use them for the manpages.
5713 Report by Benoit Sigoure.
5715 * bin/autoreconf.in: Discard stderr for $autoconf/$aclocal --help.
5717 2007-12-16 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5719 Fix some write failure cases in Autotest.

5730 (_m4_defun_pro_outer, _m4_defun_epi, _m4_defun_epi_outer)
5731 (m4_require): Use m4_do, not m4_join.
5733 Fix some whitespace tests on cygwin.
5734 * tests/tools.at (autom4te and whitespace in file names): Restore
5735 font-lock. Create $TMPDIR before it might be used.
5737 Fix spurious testsuite failure with M4 1.4.11.
5738 * tests/local.at (AT_CHECK_M4): Cater to new m4 error message.
5740 Optimize AC_REQUIRE.
5741 * lib/m4sugar/m4sugar.m4 (m4_expansion_stack_push, _m4_defun_pro)
5742 (_m4_defun_pro_outer, _m4_defun_epi, _m4_defun_epi_outer)
5743 (m4_require): Avoid extra macro calls.
5745 2007-12-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5747 * tests/torture.at (srcdir): Fix quoting.
5749 Do not pass top_srcdir to configure scripts in testsuite.
5750 * tests/autotest.at (srcdir propagation): Copy install-sh to
5752 (my only test): Drop setting of `top_srcdir'.
5753 * tests/base.at (Input/Output): Likewise.
5754 * tests/local.at (AT_CONFIGURE_AC): Copy install-sh,
5755 config.guess, and config.sub to test source tree.
5756 Drop AC_CONFIG_AUX_DIR setting.
5757 (AT_CHECK_CONFIGURE): Drop setting of `top_srcdir'.
5758 * tests/torture.at (Substitute a 2000-byte string): Drop
5759 AC_CONFIG_AUX_DIR setting, copy install-sh to test source tree.
5760 (Substitute a newline, datarootdir workaround): Likewise.
5761 (Define a newline): Adjust for linenumber changes in configure.ac.
5762 * tests/foreign.at (Libtool): Adjust comment to reflect changes.
5764 * tests/semantics.at (AC_PATH_PROGS_FEATURE_CHECK): Skip test
5765 if `pwd` contains whitespace.
5767 Quote $abs_top_srcdir in tests.
5768 * tests/local.at (AT_CHECK_PERL_SYNTAX): Likewise.
5769 * tests/tools.at (Syntax of the shell scripts): Likewise.
5771 * tests/m4sh.at (LINENO): Quote $0.
5773 Fix testsuite program wrapper for whitespace in `pwd`.
5774 The problem here is that the usual mantra is that command
5775 variables can contain arguments, thus we cannot just escape
5776 $AUTOCONF, $AUTOM4TE etc. The compromise is to put the
5777 $top_builddir/tests directory early in $PATH, so that the
5778 wrappers are found by their plain name.
5779 * tests/wrapper.as: Put $testdir early in $PATH.
5780 (AUTOCONF, AUTOHEADER, AUTOM4TE): Set to plain command names.
5782 Proper config.status --file/--header and $srcdir escaping.
5783 * lib/autoconf/status.m4 (_AC_OUTPUT_MAIN_LOOP): Quote special
5784 characters in $ac_file_inputs.
5785 (_AC_OUTPUT_FILE, _AC_OUTPUT_HEADER): eval $ac_file_inputs
5787 * tests/torture.at (datarootdir workaround): Adjust.
5788 (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS): Extend test.
5790 Fix Autotest for whitespace in `pwd`.
5791 * lib/autotest/general.m4 (AT_INIT)
5792 <at_func_create_debugging_script, Driver Loop>:
5793 Quote $at_group_dir.
5794 * tests/autotest.at (whitespace in absolute testdir): New test.
5796 * lib/autom4te.in: Quote @datadir@.
5798 Proper file name escaping in Autoconf programs and Perl modules.
5799 This includes escaping of characters special to the shell
5800 as well as special to Perl, e.g., leading `<' or `>'.
5801 For example, when $file starts with `>', `open ">$file"'
5802 wrongly tries to append to a different file.
5803 * bin/autoconf.as: Fix quoting for autom4te options.
5804 * lib/Autom4te/General.pm (shell_quote): New function, taken
5805 from coreutils, written by Jim Meyering.
5807 * bin/autom4te.in (files_to_options, handle_m4): Use shell_quote
5809 * bin/autoreconf.in (parse_args): Likewise.
5810 * bin/autoscan.in (main): Likewise.
5811 * bin/autoupdate.in (main): Likewise.
5812 * bin/autoheader.in: Likewise, fixing old insufficient escaping.
5813 * bin/ifnames.in: Likewise, XFile usage fixes.
5814 * tests/tools.at (autom4te and whitespace in file names): Extend
5815 test. Test twice, with special characters allowed on w32, and the
5816 rest. Test leading and trailing whitespace, for `open_quote'.
5817 (autotools and whitespace in file names): New, analogous test.
5818 Reported by Paul Eggert and Benoit Sigoure, additional suggestions
5819 by Russ Allbery and Eric Blake.
5822 * lib/Autom4te/Channels.pm, lib/Autom4te/Configure_ac.pm,
5823 lib/Autom4te/Struct.pm, lib/Autom4te/XFile.pm: Likewise.
5824 * lib/Autom4te/FileUtils.pm (open_quote): New function.
5825 (update_file, contents): Use it.
5827 * Makefile.am (autom4te-update): Rewrite for git.
5829 2007-12-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5831 * doc/autoconf.texi (autom4te Invocation, Autom4te Cache): Fix typos.
5833 Fix copyright years.
5834 * Makefile.am, doc/install.texi, lib/autoconf/fortran.m4,
5835 lib/autoconf/lang.m4, lib/freeze.mk: Likewise.
5837 2007-12-04 Eric Blake <ebb9@byu.net>
5839 Manually resync with gnulib, since 'make cvs-update' no longer works.

5843 When using older automake, don't downgrade build-aux/texinfo.tex.
5844 * configure.ac (AM_INIT_AUTOMAKE): Add no-texinfo.tex option.
5845 * doc/Makefile.am (TEXINFO_TEX): Add.
5847 2007-11-27 Paul Eggert <eggert@cs.ucla.edu>
5849 Fix AC_C_BIGENDIAN bug caused by new awk method of substitution.
5850 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Don't comment out the
5851 #undef as this runs afoul of our new way of creating config.h.
5852 Problem reported by Jim Meyering in
5853 <http://lists.gnu.org/archive/html/autoconf-patches/2007-11/msg00164.html>.

5857 Fix autom4te for unusual characters in input file names.
5858 * bin/autom4te.in (files_to_options): Quote active characters
5860 * tests/tools.at (autom4te and white space in file names):
5863 * doc/autoconf.texi (Limitations of Usual Tools) <awk>:
5864 Document that Tru64 awk always splits $0.
5866 2007-11-24 Stepan Kasal <kasal@ucw.cz>
5868 * lib/autotest/general.m4 (AT_INIT): Do not extract the
5869 `#AT_STOP_...' line at the end of each test.
5871 2007-11-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5873 * lib/autotest/general.m4 (AT_INIT): For awk line number
5874 extraction script, ensure `$at_group' has a defined value
5875 even for the empty set, and properly quote its usage inside
5878 2007-11-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5880 * doc/autoconf.texi (Shell Functions): New chapter. Document
5881 IRIX sh $0 issue in functions, move content from ...
5882 (Portable Shell): ... here.
5883 (Shell Script Compiler): Note that shell functions are not
5884 totally unportable any more.
5886 2007-11-22 Stepan Kasal <kasal@ucw.cz>
5887 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5889 * lib/autotest/general.m4 (AT_INIT): Exit awk script after
5890 extracting the line numbers of the last needed test.
5892 2007-11-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5894 * lib/autotest/general.m4 (AT_INIT) <at_func_create_debugging_script>:
5897 2007-11-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5899 Fix IRIX testsuite debugging failures: $0 in functions.
5900 * lib/autotest/general.m4 (AT_INIT) <at_func_create_debugging_script>:
5901 Do not use $0 inside a function, as IRIX sh will set that to the
5902 function name rather than the script invocation name.
5904 2007-11-19 Paolo Bonzini <bonzini@gnu.org>
5905 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5907 * lib/autotest/general.m4 (at_func_test): Use cached line numbers
5908 to extract test scripts.
5909 (AT_INIT): Extract and cache test script line numbers.
5911 2007-11-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5913 * lib/autotest/general.m4: Revert 2007-11-15 patch and
5914 subsequent fixups; the awk -> here-document conversion trashes
5915 performance too much with AIX sh.
5917 2007-11-18 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5919 * tests/local.at: Do not test m4, perl with AT_TESTED.
5921 Diagnose and guard against write errors dealing with config.status.
5922 The general idea is this: all write failures from `configure'
5923 writing `config.status' are indicated by $ac_write_error, which
5924 is only checked at the end. This is safe because config.status
5925 code is not executed before the file is complete. Other write
5926 failures, be they inside config.status, or in sub shell/awk
5927 scripts spawned from configure or config.status, typically need
5928 earlier checking, as their results are used right afterwards.
5929 * lib/autoconf/status.m4 (AC_OUTPUT): Initialize `ac_write_fail'
5930 before writing config.status, check afterwards.
5931 (_AC_OUTPUT_FILES_PREPARE, _AC_OUTPUT_FILE)
5932 (_AC_OUTPUT_HEADERS_PREPARE,_AC_OUTPUT_CONFIG_STATUS):
5933 Set `ac_write_error' for write failures to config.status. Barf
5934 upon write failures to temporary files.
5935 Adjust note about closing and reopening the here-document.
5936 (_AC_OUTPUT_HEADER, _AC_OUTPUT_LINK, _AC_OUTPUT_COMMAND)
5937 (_AC_OUTPUT_MAIN_LOOP): Likewise, adjust note about closing and
5938 reopening the here-document.
5939 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
5940 Ensure `ac_write_error' does not escape into config.status.
5941 Also, add a couple of code paths not yet exercised in the test
5942 suite: a config file with input from stdin, and a config header
5944 Suggestion for catching write errors by Bruno Haible.
5946 2007-11-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5948 Avoid error with Tru64 awk and testsuite lines with many words.
5949 * lib/autotest/general.m4 (AT_INIT): In the awk script that
5950 reads the testsuite, set the field separator to an unusual value,
5951 in order to not run over the limit of 199 fields. Tru64 4.0D awk
5952 even splits the input if $i, i>0, was never accessed in the script.
5954 Revert 2007-10-17 change.
5955 * TODO: Multiline args in config files and headers mean something
5956 different and are not fixed, see

5965 * doc/autoconf.texi (Generic Programs): Do not say that
5966 the *_TOOL macros canonicalize, they simply use the `host_alias'.
5968 2007-11-16 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5970 Diagnose write errors in config.status instantiations.
5971 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE)
5972 (_AC_OUTPUT_HEADER, _AC_OUTPUT_MAIN_LOOP): Bail out
5974 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
5975 Extend test to also check for some write error failures, using...
5976 <AT_CHECK_CONFIG_CREATION_NOWRITE>: ...this new macro.
5977 Report by Bruno Haible.
5980 * lib/autotest/general.m4 (AT_INIT) <at_func_log_failure>: Fix
5982 (_AT_CHECK): Use less indentation, to save space.
5984 2007-11-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5986 Add witness macro for @top_build_prefix@ substitution.
5987 * lib/autoconf/status.m4 (_AC_HAVE_TOP_BUILD_PREFIX): New macro.
5988 (_AC_OUTPUT_FILE): Mention it here.
5990 2007-11-15 Paolo Bonzini <bonzini@gnu.org>
5991 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5993 * lib/autotest/general.m4 (at_func_test): Remove.
5994 (AT_INIT): Pre-extract test groups into separate files.
5995 (AT_CLEANUP): Source pre-extracted file instead of calling at_func_test.
5996 Remove at-test-source files together with the $at_group_dir.
5997 * tests/autotest.at (Long test source lines): New test.
5999 2007-11-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6001 Shell functions and variables may share a namespace.
6002 * doc/autoconf.texi (Portable Shell): Mention Solaris sh
6005 2007-11-14 Paul Eggert <eggert@cs.ucla.edu>
6007 * lib/autoconf/types.m4 (_AC_TYPE_LONG_LONG_SNIPPET): Make comment match
6010 2007-11-14 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6012 * lib/autoconf/status.m4: Fix a couple of comment typos.
6014 * lib/m4sugar/m4sh.m4 (AS_TMPDIR): Use $as_me, not $me.
6016 2007-11-13 Jim Meyering <meyering@redhat.com>
6018 Clean up the rule to create "expr".
6019 * tests/Makefile.am (expr): Don't redirect directly to target.
6020 Redirect just once, not for each echo statement.
6021 Use $@, not literal "expr".
6023 2007-11-13 Paul Eggert <eggert@cs.ucla.edu>
6025 Don't worry about preprocessor when testing long long.
6026 See: http://lists.gnu.org/archive/html/bug-gnulib/2007-11/msg00075.html
6027 * doc/autoconf.texi (Preprocessor Arithmetic): New section.
6028 (AC_TYPE_LONG_LONG_INT, AC_TYPE_UNSIGNED_LONG_LONG_INT):
6029 These no longer check for preprocessor flaws.
6030 * lib/autoconf/types.m4 (_AC_TYPE_LONG_LONG_SNIPPET):
6031 Do not check for preprocessor flaws.
6033 2007-11-13 Jim Meyering <meyering@redhat.com>
6035 Adapt dependencies, now that a version change doesn't modify configure.ac
6036 * GNUmakefile: Remove "make clean" kludge.
6037 * lib/m4sugar/Makefile.am (version.m4): Depend on Makefile, not
6039 Don't redirect directly to target.
6040 Use $@, not literal "version.m4".
6042 2007-11-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6044 * doc/autoconf.texi (Making testsuite Scripts): Document
6045 ":;{" shorthand as in previous patch.
6047 2007-11-12 Paul Eggert <eggert@cs.ucla.edu>
6049 * doc/autoconf.texi (Limitations of Builtins): Document problem
6050 with { ... } a bit more clearly. Suggest ":;{" as a shorthand
6052 * lib/m4sugar/Makefile.am (version.m4): Detect 'echo' failure.
6053 Use ":;{" shorthand.
6054 * tests/Makefile.am ($(srcdir)/package.m4): Likewise.
6056 2007-11-12 Jim Meyering <meyering@redhat.com>
6058 Add more non-srcdir build support.
6059 * GNUmakefile (dummy): Split a long line.
6060 Add -v option to autoreconf invocation.
6062 Remove the autoreconf-provided INSTALL, so that we regenerate it.
6063 * GNUmakefile (dummy): Remove INSTALL.
6065 Remove racy commands to build scripts in bin/ and tests/.
6066 * man/Makefile.am (.x.1): Now that scripts in bin/ and tests/
6067 are guaranteed to be built, remove the rules that tried to build
6068 them. Before, with a parallel build, these rules could lead to
6069 two processes writing tests/wrapper.in concurrently.
6071 Build in man/ only *after* building in bin/ and tests/.
6072 * Makefile.am (SUBDIRS): The man-page-creation process runs $(MAKE)
6073 in both bin/ and tests/.
6075 Accommodate non-srcdir build-from-checkout.
6076 * build-aux/git-version-gen: Require an additional parameter: $srcdir.
6077 Use git's --git-dir=$srcdir/.git option.
6078 Add quotes, in case tarball_version_file contains shell meta-characters.
6079 * GNUmakefile (_curr-ver): Pass $(srcdir) to git-version-gen.
6080 * configure.ac: Pass "." to git-version-gen.
6082 Avoid spurious test failures due to version skew.
6083 * GNUmakefile (dummy): Run $(MAKE) clean after autoreconf -i.
6085 2007-11-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6087 Avoid warnings about conftest.dSYM directories on Mac OS X Leopard.
6088 * lib/autoconf/general.m4 (_AC_LINK_IFELSE, _AC_RUN_IFELSE):
6089 Remove conftest.dSYM directory.
6090 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT)
6091 (_AC_LANG_PROGRAM_C_, _AC_FC_MAIN, __AC_FC_NAME_MANGLING):
6092 Remove `conftest.*' recursively.
6093 * lib/autoconf/lang.m4 (AC_LINK_IFELSE): Likewise.
6094 * lib/autoconf/specific.m4 (_AC_SYS_LARGEFILE_MACRO_VALUE):
6096 (_AC_COMPILER_OBJEXT_REJECT): Reject *.dSYM.
6098 Report and analysis by Jeff Squyres and Peter O'Gorman.
6100 2007-11-12 Benoit Sigoure <tsuna@lrde.epita.fr>
6102 Fix typos in variable names.
6103 * tests/semantics.at (test for AC_CHECK_LIB): s/at_m/ac_m/.
6105 2007-11-11 Benoit Sigoure <tsuna@lrde.epita.fr>
6107 Document that $((expression)) is not portable.
6108 * doc/autoconf.texi (Shell Substitutions): Here.
6110 2007-11-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6112 Ignore configure --help* errors due to LINENO-impaired shells.
6113 * tests/torture.at (Configuring subdirectories, Deep Package):
6114 In the --help* tests in read-only trees, make `.' temporarily
6115 writable again for the `stderr' file, and ignore errors due to
6116 the attempt to write configure.lineno.
6117 Report by Patrick Welche.
6119 2007-11-10 Jim Meyering <meyering@redhat.com>
6121 Generate package.m4 in build-dir, not srcdir.
6122 * tests/Makefile.am (package.m4): Adjust target.
6123 Don't redirect directly to $@.
6124 (CLEANFILES): Add package.m4.
6125 ($(TESTSUITE)): Depend on just-built package.m4, not the one
6127 When running $(AUTOTEST), search "." before searching $(srcdir).
6129 Avoid a race condition that would make parallel "distclean" fail.
6130 * tests/Makefile.am (distclean-generic): Replace the default,
6131 automake-provided rule with an identical one, but with an additional
6132 dependency on distclean-local. Simply adding the dependency would
6133 cause automake not to emit the rule at all.
6134 * BUGS: Building with -jN works, now.
6136 Distribute git-version-gen.
6137 * Makefile.am (EXTRA_DIST): Add build-aux/git-version-gen,
6138 since GNUmakefile is distributed, and requires it for dist* rules.
6140 Remove two more generated files from version control.
6141 * INSTALL: Remove generated file.
6142 * lib/autoscan/autoscan.list: Remove generated file.
6144 2007-11-09 Paul Eggert <eggert@cs.ucla.edu>
6146 * GNUmakefile (PATH): Remove stray apostrophes; they become
6147 part of PATH, which isn't wanted here.
6149 2007-11-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6151 New config files output variable `top_build_prefix'.
6152 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Substitute
6154 * doc/autoconf.texi (Preset Output Variables): Document it.
6156 Report by Bob Friesenhahn.
6158 Avoid expr for arithmetic evaluation if the shell accepts $((...)).
6159 * lib/autotest/general.m4 (AT_INIT) <at_func_arith>: New
6160 function, to parametrize arithmetic with expr vs. the shell.
6161 Use it where possible.
6162 Suggestion by Benoit Sigoure.
6164 2007-11-03 Benoit Sigoure <tsuna@lrde.epita.fr>
6166 Adjust the documentation of autotest WRT atlocal.
6167 * doc/autoconf.texi (Making testsuite Scripts): It is not necessary,
6168 when using Automake, to write a rule to produce atlocal, since it's
6169 an AC_CONFIG_FILES. Mention that atlocal.in needs to be
6170 distributed, not atconfig.in.
6172 2007-11-04 Eric Blake <ebb9@byu.net>
6174 Update list information.
6175 * README: Mention new autoconf-commit list.
6176 * doc/autoconf.texi (Introduction): Mention autoconf-commit list.
6178 2007-11-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6180 * lib/autoconf/functions.m4 (_AC_FUNC_MALLOC_IF): Fix comment typo.
6182 * lib/m4sugar/Makefile.am (version.m4): Another bash bug workaround.
6184 * build-aux/.gitignore: Ignore mkinstalldirs.
6186 * doc/autoconf.texi (autoreconf Invocation): Fix an underfull line.
6188 2007-11-03 Jim Meyering <meyering@redhat.com>
6190 s/-/./ in snapshot version string: 2.61a-256-8b556 -> 2.61a.256-8b556
6191 * build-aux/git-version-gen: This syncs from coreutils.
6193 Adjust the build procedure so "make check" works reliably.
6194 * README-hacking: Include an extra step between "make" and
6195 "make check" to ensure that the latter passes.
6197 Use just-built tools, when possible.
6198 * GNUmakefile (PATH): Set and export here, ...
6199 (dummy): ... rather than here.
6201 2007-11-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6202 and Andreas Schwab <schwab@suse.de>
6204 * tests/Makefile.am ($(srcdir)/package.m4): Work around bash
6207 2007-11-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6209 * configure.ac (AC_PREREQ): Require version 2.60, for
6210 AC_PROG_SED, AC_PROG_GREP.
6212 2007-11-02 Benoit Sigoure <tsuna@lrde.epita.fr>
6213 and Jim Meyering <meyering@redhat.com>
6214 and Andreas Schwab <schwab@suse.de>
6215 and Eric Blake <ebb9@byu.net>
6217 Document a bug in GNU Bash with compound commands and redirections.
6218 * doc/autoconf.texi (Limitations of Builtins): Mention that GNU
6219 Bash doesn't properly set $? when `{ ... } >/bad' fails, and give
6222 2007-11-03 Eric Blake <ebb9@byu.net>
6224 Support m4 1.4.5 in testsuite.
6225 * tests/torture.at (Define a newline): Exclude line numbers in
6227 Reported by Ralf Wildenhues.
6229 2007-11-03 Jim Meyering <meyering@redhat.com>
6231 Remove automake-provided files from version control.
6232 * build-aux/elisp-comp: Remove file.
6233 * build-aux/install-sh: Remove file.
6234 * build-aux/missing: Remove file.
6235 * build-aux/mdate-sh: Remove file.
6236 * build-aux/.gitignore: New file.
6237 Suggestion from Ralf Wildenhues.
6239 2007-11-03 Eric Blake <ebb9@byu.net>
6241 Adjust version comparison to account for git snapshot numbers.
6242 * lib/m4sugar/m4sugar.m4 (_m4_version_unletter): Also treat - as a
6243 component separator.
6244 * doc/autoconf.texi (Number processing Macros)
6245 <m4_version_compare>: Document this change.
6246 * tests/m4sugar.at (m4@&t@_version_compare): Test it.
6248 2007-10-30 Bruno Haible <bruno@clisp.org>
6250 * lib/autoconf/types.m4 (_AC_TYPE_LONG_LONG_SNIPPET): New macro,
6251 extracted from AC_TYPE_LONG_LONG_INT and AC_TYPE_UNSIGNED_LONG_LONG_INT.
6252 (AC_TYPE_LONG_LONG_INT, AC_TYPE_UNSIGNED_LONG_LONG_INT): Use it.
6253 Fixes problem with Sun C 5.[0-8] in 32-bit mode, reported in
6254 <http://lists.gnu.org/archive/html/autoconf-patches/2007-10/msg00210.html>
6255 Suggested by Paul Eggert.
6257 2007-10-28 Jim Meyering <meyering@redhat.com>
6259 * README-hacking: Autoconf, Automake, and Perl are required to build.
6260 List Gzip and Tar separately. Suggested by Ralf Wildenhues.
6262 2007-10-28 Jim Meyering <meyering@redhat.com>
6264 README-hacking: Recommend running autoreconf -vi.
6265 * GNUmakefile (dummy): Use autoreconf -i, with appropriate PATH,
6266 so that we use just-built tools when they're available.
6267 Suggestions from Ralf Wildenhues.
6269 2007-10-28 Jim Meyering <meyering@redhat.com>
6271 Make inter-release --version output more useful.
6273 Now, each unofficial build has a version "number" like 2.61a-19-58dd,
6274 which indicates that it is built using the 19th change set
6275 (in _some_ repository) following the "v2.61a" tag, and that 58dd
6276 is a prefix of the commit SHA1.
6277 * build-aux/git-version-gen: New file.
6278 * configure.ac: Run it to set the version.
6279 (AM_INIT_AUTOMAKE): Don't check NEWS here.
6280 * Makefile.am (dist-hook): Arrange so that .version appears only
6281 in distribution tarballs, never in a checked-out repository.
6282 * .gitignore: Add .version here, too. Just in case.
6283 * tests/Makefile.am ($(srcdir)/package.m4): Depend on Makefile,
6284 not configure.ac, now that the version number changes automatically.
6286 Ensure that $(VERSION) is up to date for dist-related targets.
6287 * GNUmakefile: Arrange to rerun autoconf, if the version reported by
6288 git-version-gen doesn't match $(VERSION), but only for dist targets.
6290 2007-10-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6292 Fix `Deep Package' failure with a configure script early in PATH
6293 * tests/torture.at (Deep Package): Add `.' early in PATH.

6303 * README-hacking: New file: how to build from just-checked-out sources.
6305 2007-10-23 Eric Blake <ebb9@byu.net>
6307 Improve corner case of m4_expand.
6308 * lib/m4sugar/m4sugar.m4 (m4_expand, _m4_expand): Rewrite more

6322 problem reported by Bruno Haible in
6323 <http://lists.gnu.org/archive/html/bug-autoconf/2007-10/msg00027.html>.
6325 2007-10-22 Eric Blake <ebb9@byu.net>
6327 * doc/autoconf.texi (Particular Types): Mention bug in HP-UX 11.00
6330 2007-10-22 Paul Eggert <eggert@cs.ucla.edu>
6332 Don't check for bug in HP-UX 11.00 cpp.
6333 * lib/autoconf/types.m4 (AC_TYPE_UNSIGNED_LONG_LONG_INT):
6334 Use -1ull rather than -1u, since that causes problems with gnulib; see
6335 <http://lists.gnu.org/archive/html/bug-gnulib/2007-10/msg00329.html>.
6337 2007-10-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

6353 escaping of backslash in here-documents.
6355 Fix `Deep Package' test failure on FreeBSD.

6357 unnecessarily. Do not try running `/bin/sh configure' with a
6358 configure script to be found in $PATH, if the shell does not do
6359 this resolution. Fixes test failure on FreeBSD.
6361 Fix config header generation with AIX awk.
6362 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS_PREPARE): In awk
6363 script, use helper array D_is_set, as `" 0"' does not evaluate
6364 to true for AIX awk.
6366 2007-10-21 Eric Blake <ebb9@byu.net>

6401 * lib/autotest/general.m4 (BANNERS): New named diversion.
6402 (TESTS_END): Diversion no longer used.
6403 (AT_INIT) <at_func_banner, BANNERS>: Factor all banners into a
6404 shell function, which prints only as needed, using an associative
6405 array of banner text from a special diversion.
6406 <PARSE_ARGS_END>: No longer need awk to find banners.
6407 <TESTS>: Banners are no longer processed by main driver loop, so
6408 we no longer need case statement.
6409 (AT_BANNER): Rewrite to populate new diversion.
6410 (AT_SETUP): Each test invokes its own banner. No output is needed
6411 to the TESTS diversion.

6438 duplication bug by using new macro.
6439 (AT_INIT) <at_tested>: Restore newline separators. Invoke tested
6440 programs with stdin redirected, so programs that don't
6441 understand --version won't try to behave interactively.
6442 * tests/autotest.at (Tested programs): Catch this bug.

7544 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't look
7545 for a.* when searching for executables, as this prevents users
7546 from having files like a.c. Problem reported by Ralf Wildenhues in:

7559 AC_CHECK_TYPE, AC_CHECK_TYPES.
7560 * doc/autoconf.texi (Generic types): C types must be type-names
7561 (the C terminology), not type-ids (the C++ term). C++ types
7562 must not be anonymous.
7563 * lib/autoconf/types.m4 (_AC_CHECK_TYPE_NEW): Remove special case
7564 for C++; this drops support for anonymous struct and union types,
7565 which were problematic anyway.

7582 on types imposed by AC_CHECK_TYPE, AC_CHECK_TYPES.
7583 (Generic Compiler Characteristics): AC_CHECK_SIZEOF now works
7584 with objects too. Document the restrictions on its use.
7585 Document the restrictions on AC_CHECK_ALIGNOF's type argument.
7586 * lib/autoconf/types.m4 (_AC_CHECK_TYPE_NEW):
7587 For C, just try sizeof (TYPE) and sizeof ((TYPE)); if the former
7588 works but the latter doesn't, then it's a valid type.
7589 This lets people use function types and so forth.
7590 For C++ there doesn't seem to be a simple solution, so leave it alone.
7591 (AC_CHECK_SIZEOF): Allow argument to be a variable.
7592 (AC_CHECK_SIZEOF, AC_CHECK_ALIGNOF): Don't bother to invoke
7593 AC_CHECK_TYPE; that wasn't documented or necessary.
7595 2007-04-11 Stepan Kasal <kasal@ucw.cz>
7597 * lib/autoconf/general.m4 (_AC_LINK_IFELSE): Skip AS_TEST_X
7598 when cross-compiling.

7618 * doc/autoconf.texi (Here-Documents, Limitations of Builtins):
7619 (Limitations of Usual Tools): Don't say "older" if Solaris 10 by
7620 default still has the problem. Problem reported by Bruce Korb.

7641 checks for unsigned long long int.
7643 2007-03-19 Paul Eggert <eggert@cs.ucla.edu>
7645 * doc/autoconf.texi (Limitations of Usual Tools): Warn about other
7646 nonstandard grep R.E. escape sequences.
7648 2007-03-17 Jim Meyering <jim@meyering.net>
7650 * doc/autoconf.texi: Adjust grammar around use of "heuristics".
7651 (Limitations of Usual Tools): Also list \< and \>, and mention that
7652 HP-UX's grep, like the one from Solaris, does not support that syntax.
7654 2007-03-09 Stepan Kasal <kasal@ucw.cz>
7656 * doc/autoconf.texi (Specifying Names): `--host' does not
7657 change the build type.

7695 status of rm so we know when it failed.
7696 If cleaning of test dir failed before running the test, warn.
7697 Output the line separator in verbose mode before the warning
7698 to make clear the warning belongs to the following test.

7763 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Also
7764 AC_SUBST([MKDIR_P]), so that Automake < 1.10 will pick up its
7765 trace, if a package uses AC_PROG_MKDIR_P explicitly. The actual
7766 substitution will still be done by the special code.

7790 * lib/autoconf/programs.m4 (AC_PROG_SED): When closing a pipe
7791 early on the reader side, drop stderr of the input to avoid
7792 `broken pipe' error output; this may happen even with shell
7793 builtin `echo' of some bash versions. Reports by Ian Macdonald

7810 * doc/autoconf.texi (Signed Overflow Examples): Give more
7811 discussion about the allow_superuser_privileges example,
7812 and change it a bit to make things clearer.
7813 (Optimization and Wraparound): Clarify whether the compiler
7814 will generate an infinite loop for the example derived from
7815 Autoconf's mktime test.
7816 (Signed Overflow Advice): Say that -ftrapv is meant for debugging.
7817 Also, clarify unsigned multiplication overflow.
7819 2007-01-04 Eric Blake <ebb9@byu.net>
7821 * bin/Makefile.am (RELEASE_YEAR): New macro.
7822 (edit): Use it to supply correct copyright year to scripts.

7824 * bin/autoheader.in ($version): Likewise.
7825 * bin/autom4te.in ($version): Likewise.

7831 2007-01-02 Paul Eggert <eggert@cs.ucla.edu>
7833 * doc/autoconf.texi (Integer Overflow): Revised based on today's
7834 feedback. The most important changes document what happens when
7835 you convert an out-of-range value to a signed integer type, and
7836 say that (sum < a) != (b < 0) reliably detects overflow when sum =
7839 * doc/autoconf.texi (Integer Overflow): Greatly expand and
7840 rewrite, taking notions from the recent discussion on the gcc and
7841 autoconf mailing lists; please see
7842 http://lists.gnu.org/archive/html/autoconf-patches/2006-12/msg00091.html
7843 and follow the many links.
7844 (Integer Overflow Basics, Signed Overflow Examples):

7846 (Signed Integer Division): New sections.
7848 2006-12-28 Steven G. Johnson <stevenj@alum.mit.edu>
7850 * lib/autoconf/general.m4 (AC_DEFINE_TRACE): Don't include
7851 preprocessor macro arguments in traced name.
7852 * doc/autoconf.texi (Defining symbols): Document longstanding
7853 support for AC_DEFINE-ing macros with arguments, and document
7854 behavior when the same variable has multiple AC_DEFINEs.
7855 * lib/autoconf/fortran.m4 (_AC_FC_WRAPPERS): Revert to the
7856 old implementation which AC_DEFINEs the FC_FUNC and FC_FUNC_
7857 macros directly, giving much shorter and simpler code.
7859 2006-12-28 Malcolm Purvis <malcolmp@xemacs.org> (trivial change)
7861 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Insert a
7862 space before "$ac_configure_args" to prevent a 'config.status
7863 --recheck' failure if ac_configure_args doesn't contain a leading
7864 space. This works around a problem with the XEmacs configure.ac,
7865 which uses the (undocumented) ac_configure_args variable
7866 inconsistently with Autoconf.
7868 2006-12-22 Paul Eggert <eggert@cs.ucla.edu>
7870 * lib/autoconf/functions.m4 (AC_FUNC_MKTIME):
7871 Include <limits.h>, and use its INT_MAX to rewrite the
7872 j loop so that it does not overflow 'int'. Problem reported by
7874 <http://lists.gnu.org/archive/html/bug-gnulib/2006-12/msg00084.html>.
7875 Play it safe by shifting left by 1 rather than multiplying by 2,
7876 as GCC is less likely to optimize this away when the value
7877 is signed (when it assumes overflow leads to undefined behavior).
7878 Also, don't assume time_t uses two's complement.
7880 2006-12-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7882 * tests/torture.at (Substitute a 2000-byte string): Avoid using
7883 a 10kB long (multi-line) string literal, OpenServer 5.0.7 ksh
7884 dumps core on it. Report by Tim Rice.

7902 (Configure Option Checking). Tighten up the wording a bit.
7903 (External Software, Package Options): Cross-reference to Option
7904 Checking, and use this to shorten our section.
7905 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Prefer test -n
7906 "$x" to test "x$foo" != x.
7907 * lib/autoconf/status.m4 (AC_OUTPUT): Likewise.
7908 Don't warn if $enable_option_checking is "no".
7909 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Initialize
7910 ac_unrecognized_opts to the empty string.
7911 Don't echo the unrecognized opts, as this might mishandle
7912 backslashes or leading -.

7914 usage next to the other --disable-FEATURE options in the
7917 2006-12-18 Steven G. Johnson <stevenj@alum.mit.edu>
7919 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS, _AC_INIT_PARSE_ARGS):
7920 (_AC_INIT_PARSE_ENABLE2, _AC_INIT_HELP, _AC_ENABLE_IF):
7921 Print warning for unrecognized --with and --enable options
7922 (AC_DISABLE_OPTION_CHECKING): New macro to disable warnings.
7923 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS, _AC_OUTPUT_SUBDIRS):
7924 Disable option checking when subdirs are configured.
7925 (AC_OUTPUT): If warnings are enabled, print warning about
7926 unrecognized --with and --enable options at the end of
7927 the configure output (as well as at the beginning).
7928 * doc/autoconf.texi (Option Checking): New node.
7929 Document new option warning functionality.
7931 2006-12-16 Eric Blake <ebb9@byu.net>
7933 * configure.ac (AC_INIT): Bump version, since 2.61a is released.
7934 * NEWS: Start news for current version.
7936 2006-12-15 Paul Eggert <eggert@cs.ucla.edu>
7938 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT):
7939 Define HAVE_GETMNTENT to 1, not to the empty string.
7940 Problem originally reported by Jochen Friedrich in
7941 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=403243>.
7943 This change prompted by a problem report by Andrey Simonenko in
7944 <http://lists.gnu.org/archive/html/bug-autoconf/2006-12/msg00026.html>.
7945 * doc/autoconf.texi (Defining Symbols): AC_DEFINE works for
7946 object-like macros only, in the traditional portable character
7948 * lib/autoconf/general.m4 (AC_DEFINE_TRACE_LITERAL):
7949 Warn about attempts to define things that are not identifiers.
7950 * lib/autoconf/fortran.m4 (_AC_FC_WRAPPERS): Rewrite to avoid
7951 awful hack that AC_DEFINEd macro names containing parentheses.
7953 2006-12-12 Paul Eggert <eggert@cs.ucla.edu>
7955 * doc/autoconf.texi: Undo some of the 2006-12-10 change. It was
7956 too drastic, even if Texinfo in theory requires it for info mode.
7958 (config.status Invocation): Renamed back from Recreating a
7960 (Obsolete config.status Use): Renamed back from Obsolete Recreation.
7961 (Autoconf 2.13): Renamed back from 20th-century Autoconf 2.
7963 2006-12-11 Paul Eggert <eggert@cs.ucla.edu>
7965 * NEWS: Version 2.61a.
7967 2006-12-11 Paul Eggert <eggert@cs.ucla.edu>
7968 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7970 * NEWS: Document changes with echo and printf, and the lack
7971 of limits on the total size of multi-line values of substituted
7972 variables, and the AC_FUNC_FSEEKO fix.
7974 2006-12-10 Paul Eggert <eggert@cs.ucla.edu>
7976 * doc/autoconf.texi (Writing Autoconf Input): Renamed from
7977 Writing configure.ac.
7978 (Autoconf Input Layout): Renamed from configure.ac Layout.
7979 (Recreating a Configuration): Renamed from config.status Invocation.
7980 (Obsolete Recreation): Renamed from Obsolete config.status Use.
7981 (acconfig Header): Renamed from acconfig.h.
7982 (20th-century Autoconf 2): Renamed from Autoconf 2.13.
7983 (Writing Testsuites): Renamed from Writing testsuite.at.
7984 (Autom4te Cache): Renamed from autom4te.cache.
7986 * BUGS: Remove mention of VPATH problem, since it's now documented
7987 not to be a bug in the Autoconf build procedure itself, but rather
7988 a problem with the proprietary `make' programs.
7990 * doc/autoconf.texi (Build Directories): Add a cross reference
7993 * build-aux/config.guess, build-aux/config.sub, build-aux/texinfo.tex:
7994 * doc/standards.texi: Sync from gnulib.
7996 * man/autoconf.1, man/autoheader.1, man/autom4te.1, man/autoreconf.1:
7997 * man/autoscan.1, man/autoupdate.1, man/config.guess.1:
7998 * man/config.sub.1, man/ifnames.1: Remove from CVS, since they're
7999 generated automatically.
8001 2006-12-06 Paul Eggert <eggert@cs.ucla.edu>
8003 * lib/autoconf/c.m4 (_AC_PROG_CC_C89): Also try -xc99=all, for Sun
8004 C 5.8 on Solaris 10. Using -xc99=all rather than -xc99 bypasses
8005 the buggy -xc99 option of Forte Developer 7 C on Solaris 9.
8007 2006-12-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8009 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Drop the
8010 `CEOF$ac_eof' special marker, the awk script cannot contain a
8011 line matching `^CEOF', so this is not needed any more.
8012 * tests/torture.at (Substitute a newline): Expose the `%!_!# '
8013 special marker in the test.
8015 2006-12-06 Stepan Kasal <kasal@ucw.cz>
8017 * tests/tools.at (autom4te preselections): Use `find -newer';
8018 remove one of the sleeps.
8020 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE): Make it
8021 more readable, using ...
8022 (_AC_INIT_PARSE_ENABLE2): ... this new helper macro.
8024 * doc/autoconf.texi (autoheader Invocation): Do not double-
8025 quote the parameter of `AH_BOTTOM' in the example.
8027 2006-12-05 Stepan Kasal <kasal@ucw.cz>
8029 * doc/autoconf.texi (Configuration Headers): Remove the
8030 example with multiple input files.
8031 (autoheader Invocation): Encourage `AH_BOTTOM', discouraging
8032 multiple input files.
8034 2006-12-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8036 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): When
8037 creating the awk substitution script, handle one input line at a
8038 time, so that the maximum length of a substituted (multi-line)
8039 value is not limited by the size of the sed pattern space.
8040 The trade-off is a slightly repetitive sed script.
8041 * doc/autoconf.texi (Limitations of Usual Tools): Branch labels
8042 can only have up to 7 characters, due to Solaris 10 /bin/sed.
8043 * tests/torture.at (Substitute a 2000-byte string): Increase the
8044 test with several long lines, they should not be caught by sed
8047 * tests/tools.at (autom4te preselections): New test, to flag
8048 entries missing from autom4te.cfg.
8049 Report by David Byron <dbyron@hheld.com>.
8051 * tests/torture.at (Substitute a 2000-byte string): Actually use
8052 AC_PROG_AWK, so the last change works as intended.
8053 (Substitute and define special characters): Likewise.
8054 (Substitute a newline): Likewise.
8056 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Use `$AWK'
8057 instead of `awk' consistently.
8058 (_AC_OUTPUT_CONFIG_STATUS): Initialize $AWK.
8059 * tests/torture.at (Torturing config.status): Test both the
8060 result of AC_PROG_AWK and plain awk.
8061 (Substitute a 2000-byte string): Likewise.
8062 (Substitute and define special characters): Likewise.
8063 (Substitute a newline): Likewise.
8065 2006-12-04 Paul Eggert <eggert@cs.ucla.edu>
8067 * lib/autoconf/functions.m4 (AC_FUNC_FSEEKO): Check that fseeko
8068 can be assigned to a function pointer. Problem reported by
8069 Peter Palfrader in <http://bugs.debian.org/401377>. Based on
8070 part of a patch by Ralf Wildenhues in that same bug report.
8072 2006-12-01 Paul Eggert <eggert@cs.ucla.edu>
8074 * tests/mktests.sh (ac_exclude_list): Exclude AC_FUNC_SETVBUF_REVERSED.
8075 * tests/semantics.at (AC_FUNC_SETVBUF_REVERSED): New test.
8077 2006-12-01 Eric Blake <ebb9@byu.net>
8079 * lib/autoconf/c.m4 (AC_LANG_INT_SAVE): Avoid newline, to aid in
8080 cross-compiling from cygwin to mingw.
8081 Reported by Bob Rossi. This resurrects the 2000-11-30 patch to
8082 aclang.m4, which was mistakenly removed in the 2001-09-17 patch
8083 to lib/autoconf/c.m4.
8085 2006-12-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8087 * lib/m4sugar/m4sh.m4 (_AS_ECHO_PREPARE): Use a longer test
8088 string for more reliable failure. Wrap the entire test that
8089 causes the broken Solaris printf to dump core, in a subshell,
8090 so the segmentation fault message is reliably suppressed.
8091 Fix shell expansion errors by using /usr/ucb/echo always;
8092 avoid an error on systems without it by another subshell.
8093 Avoid m4 expansion of `$1'. Set the zeroth argument of the
8094 subshell-$as_echo to `as_echo', for better error message.
8096 2006-11-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8098 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): If `BASH_ARGV' or
8099 `BASH_SOURCE' contain a newline, set them to empty, as they may
8102 2006-11-27 Paul Eggert <eggert@cs.ucla.edu>
8104 Turn AC_FUNC_SETVBUF_REVERSED into a noop. It's been obsolete for
8105 years and is too hard to maintain now. The last straw was
8106 reported by Jerker Baeck in
8107 <http://lists.gnu.org/archive/html/autoconf/2006-11/msg00102.html>.
8108 * NEWS: AC_FUNC_SETVBUF_REVERSED is now obsolete.
8109 * doc/autoconf.texi (Particular Functions): Move
8110 AC_FUNC_SETVBUF_REVERSED from here...
8111 (Obsolete Macros): ... to here. Say that it does nothing now.
8112 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
8113 Turn into (almost) a no-op.
8115 * lib/autoconf/c.m4 (AC_PROG_GCC_TRADITIONAL, AC_C_CONST):
8117 Do not recommend via AN_FUNCTION, AN_IDENTIFIER, or AN_HEADER.
8118 These macros are obsolescent and new applications shouldn't need them.
8119 * lib/autoconf/functions.m4 (AC_FUNC_CLOSEDIR_VOID, AC_REPLACE_FNMATCH):
8120 (AC_FUNC_GETLOADAVG, AC_FUNC_GETPGRP, AC_FUNC_MEMCMP):
8121 (AC_FUNC_SELECT_ARGTYPES, AC_FUNC_SETPGRP, AC_FUNC_STAT, AC_FUNC_LSTAT):
8122 (AC_FUNC_STRFTIME, AC_FUNC_SETVBUF_REVERSED, AC_FUNC_UTIME_NULL):
8123 (AC_FUNC_VPRINTF): Likewise.
8124 * lib/autoconf/headers.m4 (AC_HEADER_DIRENT, AC_HEADER_STAT):
8125 (AC_HEADER_STDC, AC_HEADER_SYS_WAIT, AC_HEADER_TIME): Likewise.
8126 * lib/autoconf/types.m4 (AC_STRUCT_TM): Likewise.
8128 * doc/autoconf.texi (Setting Output Variables): Mention that
8129 @VAR1@VAR2 has unspecified behavior. Problem reported by
8131 * NEWS: Mention this.
8133 * Makefile.am: Put only a single '#' into the copyright notice,
8134 so that it's also present in the output file. Standardize wording
8135 in makefile copyright notices to match GNU coding standards.
8136 * bin/Makefile.am: Likewise.
8137 * doc/Makefile.am: Likewise.
8138 * lib/Makefile.am: Likewise.

8144 * man/Makefile.am: Likewise.
8145 * tests/Makefile.am: Likewise.
8146 * lib/emacs/Makefile.am: Remove copyright notice; it's just a
8149 2006-11-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8151 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Fix error
8152 in the sed script that mangles the awk script: delete up to the
8153 first exclamation mark only.
8154 * tests/torture.at (Substitute and define special characters):
8157 2006-11-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8159 Rewrite config files generation: avoid quadratic growth in
8160 the number of substituted variables by using awk instead of sed
8161 for the bulk of the substitutions.
8162 * NEWS: Mention this.
8163 * doc/autoconf.texi (Setting Output Variables): `|#_!!_#|' is also
8164 forbidden in the output (and thus input) file.
8165 * lib/autoconf/status.m4 (_AC_AWK_LITERAL_LIMIT): New macro.
8166 (_AC_OUTPUT_FILES_PREPARE): Instead of several sed scripts,
8167 generate just one large awk script for substitutions,
8168 eliminating much of the earlier complexity, while adding some
8169 new complexity. Only expand the substitution templates at
8170 configure time, for smaller configure script size. If
8171 _AC_SUBST_FILES are used, test 'awk' for working getline support
8172 at config.status time. If absent, interpolate through the
8173 shell. The awk script was written with much help
8174 from Paolo Bonzini and Paul Eggert.
8175 (_AC_SED_CMD_NUM, _AC_SED_DELIM_NUM, _AC_SED_FRAG): Removed.
8176 (_AC_SED_FRAG_NUM): Likewise.
8177 (_AC_SUBST_CMDS): Renamed from...
8178 (_AC_SED_CMDS): ...this.
8179 (_AC_OUTPUT_FILE): Use _AC_SUBST_CMDS.
8180 * tests/torture.at (Substitute a 2000-byte string): Also
8181 substitute a line with 1000 words, and a variable with several
8183 (Substitute and define special characters): Test awk special
8184 characters, and put substitution input strings `@foo@' in the
8185 output, to test that no recursion happens; test several other
8186 combinations from Paolo Bonzini.
8188 2006-11-25 Paul Eggert <eggert@cs.ucla.edu>
8190 * lib/autotest/general.m4 (AT_INIT): Undo recent changes
8191 that replaced echo with AS_ECHO where this wasn't necessary.
8192 Problem reportd by Ralf Wildenhues.
8193 * lib/m4sugar/m4sh.m4 (_AS_ECHO_PREPARE): Port to Solaris 7,
8194 where "/usr/bin/printf '%s\n' S" dumps core if S is long.
8195 This is Sun bug 4206210. Problem reportd by Ralf Wildenhues.
8197 2006-11-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8199 * lib/freeze.mk (GREP): Removed, no need to initialize this.
8201 2006-11-21 Paul Eggert <eggert@cs.ucla.edu>
8203 * doc/autoconf.texi (Limitations of Usual Tools): Don't claim
8204 that traditional Awk lacks 3-arg "split". It has it.
8205 Mention that FS must be a single character, and a few other
8206 99-byte limits of traditional Awk.
8207 Mention that if (i in a) doesn't work with traditional Awk.
8209 2006-11-18 Paul Eggert <eggert@cs.ucla.edu>
8211 * tests/autotest.at (BSx641-newline in command):
8212 (BS-BS-newline in command, BSx640-newline in command):
8213 (Newline-CODE-BS-newline in command):
8214 (Single-quote-BS-newline in command):
8215 (Single-quote-newline-BS-newline in command):
8216 Use printf '%s\n' instead of echo, for portability to hosts
8217 where echo interprets backslashes. This will break on hosts
8218 that lack printf, but for now let's assume all such hosts
8219 are dead (if not, we should get reports of test failures).
8221 2006-11-17 Paul Eggert <eggert@cs.ucla.edu>
8223 'echo' has some portability problems, when given a first argument
8224 with a leading '-', or when given any argument containing '\'.
8225 Avoid using 'echo' in these cases.
8226 * bin/Makefile.am $(bin_SCRIPTS): Rewrite to avoid 'echo' entirely.
8227 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX, AC_PROG_OBJC): Likewise.
8228 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
8229 * lib/autotest/general.m4 (AT_INIT): Likewise.
8230 * bin/autoconf.as: Use AS_ECHO rather than plain echo, when the
8231 argument might be unportable.
8232 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Likewise.
8233 * lib/autoconf/erlang.m4 (AC_LANG(Erlang)): Likewise.

8237 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE, _AC_INIT_PREPARE):
8238 (_AC_ARG_VAR_VALIDATE, AC_ARG_PROGRAM, _AC_MSG_LOG_CONFTEST):
8239 (AC_RUN_LOG, _AC_RUN_IFELSE, _AC_LIBOBJS_NORMALIZE): Likewise.
8240 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Likewise.

8249 (_AS_BASENAME_SED, _AS_DIRNAME_SED, AS_MKDIR_P, AS_TMPDIR, AS_UNAME):
8250 (AS_TR_SH, AS_TR_CPP, AS_VAR_GET): Likewise.
8251 * bin/autoconf.as: Redo verbose flag implementation, as the old
8252 scheme wouldn't work with AS_ECHO.
8253 * lib/autotest/general.m4 (AT_INIT): Likewise.
8254 * lib/autoconf/general.m4 (AC_MSG_RESULT, AC_MSG_RESULT_UNQUOTED):
8255 Don't use ECHO_T, since ECHO_N is now reliable.
8256 * lib/autotest/general.m4 (AT_INIT): Likewise.
8257 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Use sed "$script"
8258 rather than using a here-document to put the script into a file.
8259 (_AC_DO_ECHO): Hoist the eval out of the echo, so that we can
8261 * lib/m4sugar/m4sh.m4 (AS_VAR_GET): Likewise.
8262 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Use
8263 AS_ECHO_N rather than ECHO_N and ECHO_C. This doesn't fix any
8264 bug, but we might as well stop using ECHO_N and ECHO_C internally.
8265 * lib/autotest/general.m4 (AT_SETUP): Likewise.
8266 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N): Likewise.
8267 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
8268 (_AC_OUTPUT_MAIN_LOOP): Rework echo so that it has just one
8269 operand, as AS_ECHO requires. Avoid double file name expansion.
8270 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Invoke _AS_ECHO_PREPARE.
8271 Don't set as_nl, since _AS_ECHO_PREPARE does that now.
8272 (_AS_PREPARE): Comment that _AS_ECHO_N_PREPARE is just for user code.
8273 (AS_ECHO, AS_ECHO_N, _AS_ECHO_PREPARE): New macros.
8274 * tests/c.at (AC_PROG_CPP without warnings, AC_PROG_CPP via CC):
8275 Double-quote strings that would otherwise contain M4 comments.
8276 * tests/m4sh.at (AS_ECHO and AS_ECHO_N): New test.
8278 * configure.ac (AC_INIT): Bump to 2.61a.
8281 2006-11-17 Paul Eggert <eggert@cs.ucla.edu>
8285 * configure.ac (AC_INIT): Bump to 2.61.
8288 * tests/autotest.at (Macro with backslash in a test title):
8289 Comment out for now, as this tests neither fails nor passes
8290 reliably. Problem reported by Ralf Wildenhues.
8292 2006-11-16 Paul Eggert <eggert@cs.ucla.edu>
8294 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE): Fix some typos
8295 in previous change, which caused test failures.
8297 2006-11-16 Stepan Kasal <kasal@ucw.cz>
8299 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Factor out
8300 code for --enable, --disable, --with, and --without to...
8301 (_AC_INIT_PARSE_ENABLE): ... a new macro.
8302 * doc/autoconf.texi (Package Options):

8307 Import these changes from config via gnulib:
8309 2006-11-15 Ben Elliston <bje@gnu.org>
8311 From Josselin Mouette <joss@debian.org>:

8334 2006-11-15 Karl Berry <karl@gnu.org>
8336 * standards.texi: core -> memory, throughout.
8337 (CPU Portability): show correct example of calling write
8338 on a char value; thanks to Paul Eggert for the code.
8339 Both of these suggestions from Eugene Y. Vasserman.

8358 2006-11-13 Bruno Haible <bruno@clisp.org>
8360 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): For --with, --without
8361 options, transliterate also dots to underscores.

8364 first argument may also contain dots.
8366 2006-11-09 Paul Eggert <eggert@cs.ucla.edu>
8368 * tests/mktests.sh (ac_exclude_list): Exclude AC_PROG_CXX_C_O, for
8369 benefit of platforms like Solaris+GCC where it is common to have a
8370 non-working g++ installation.
8372 2006-11-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8373 and Joel E. Denny <jdenny@ces.clemson.edu>
8374 and Paul Eggert <eggert@cs.ucla.edu>

8377 and non-portable sed scripts, and use $CONFIG_SHELL when invoking
8380 2006-11-08 Paul Eggert <eggert@cs.ucla.edu>
8382 * lib/autoconf/types.m4 (AC_TYPE_LONG_LONG_INT): Set
8383 ac_cv_type_long_long_int to 'yes' instead of 'cross-compiling'.
8384 Imported from a similar patch to gnulib by Bruno Haible.

8415 Single-quote in a test title,
8416 Double-quote in a test title): Don't expect failure anymore.
8417 (Backslash in a test title): Put a non-whitespace character after the
8418 backslash so that Bourne shells might actually see it as an escape
8420 (Brackets in a test title,
8421 Pound in a test title,
8422 Comma in a test title,
8423 Quoted Macro in a test title,

8428 Macro with backslash in a test title): New tests expected to fail.
8429 * tests/torture.at (#define header templates): M4-quote this title in
8430 AT_SETUP call so that no M4 code is commented inadvertently somewhere.
8431 The visible effect was a stray [] in the testsuite output.
8433 2006-10-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8435 * doc/autoconf.texi (Limitations of Builtins): Do not invoke
8436 `trap ... 0' inside a function, for AIX sh.
8438 2006-10-26 Paul Eggert <eggert@cs.ucla.edu>
8440 * tests/base.at (AC_COMPUTE_INT): Test **0** rather than 1 / 0,
8441 since powerpc-apple-darwin8-gcc-4.0.1 (Apple Computer, Inc. build
8442 5363) simply issues a warning when dividing by zero at compile
8443 time. Problem reported by Elias Pipping.
8445 2006-10-26 Eric Blake <ebb9@byu.net>
8448 * doc/autoconf.texi (Evaluation Macros): Improve the example to
8449 show effect on macros that expand with commas.

8477 If FUNCTION-BODY is nonempty, use AC_LINK_IFELSE rather than
8478 AC_COMPILE_IFELSE, to work around problem with OSF/1 4.0F fseeko
8479 reported by Nelson H. F. Beebe for Coreutils 6.4.
8481 * tests/tools.at (autoconf --trace: user macros): Remove test
8482 for tracing multiline macros, since m4 1.4.7a uses a different
8483 way to number lines. Problem reported by Ralf Wildenhues.

8559 2006-10-14 Paul Eggert <eggert@cs.ucla.edu>
8561 (Imported from Automake.)
8562 * build-aux/install-sh (posix_mkdir): Reject FreeBSD 6.1 mkdir -p -m,
8563 which incorrectly sets the mode of an existing destination
8564 directory. In some cases the unpatched install-sh could do the
8565 equivalent of "chmod 777 /" or "chmod 0 /" on a buggy FreeBSD
8566 system. We hope this is rare in practice, but it's clearly worth
8567 fixing. Problem reported by Alex Unleashed in
8568 <http://lists.gnu.org/archive/html/bug-autoconf/2006-10/msg00012.html>.
8569 Also, don't bother to check for -m bugs unless we're using -m;
8570 suggested by Stepan Kasal.

8619 added to the template can get mangled.
8621 2006-10-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8623 * lib/autoconf/functions.m4 (AC_FUNC_OBSTACK): In the test,
8624 include the default headers, and redefine obstack_chunk_alloc
8625 and obstack_chunk_free. Fixes false failure with glibc.

8644 * lib/autoconf/specific.m4 (AC_USE_SYSTEM_EXTENSIONS): Likewise.
8646 * lib/m4sugar/m4sh.m4 (AS_TEST_X): New macro.
8647 (AS_EXECUTABLE_P): Use as_test_x rather than as_executable_p.
8648 (_AS_TEST_PREPARE): Set as_test_x rather than as_executable_p.
8649 Use a better substitute, by inspecting the output of "ls"
8650 rather than just using ":".
8651 * lib/autoconf/general.m4 (_AC_LINK_IFELSE): Use AS_TEST_X
8652 rather than AS_EXECUTABLE_P, since we needn't worry about
8653 non-regular files here.
8655 * NEWS: Autoconf-generated shell scripts no longer export BIN_SH,
8656 due to configuration hassles with this. See Tonya Underwood's report

8669 initialization which is not inherited through the environment
8670 (_AS_BOURNE_COMPATIBLE): ... to this new macro.

8680 * lib/autoconf/c.m4 (_AC_PROG_PREPROC_WORKS_IFELSE): Remove
8681 comment about ac_cpp_err; it was incorrect, and anyway
8682 ac_cpp_err is being removed below.
8683 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE): Don't
8684 set ac_cpp_err to 'yesyes' if preproc_warn_flag and werror_flag
8685 are both 'yes'. In fact, don't bother setting ac_cpp_err at all;
8687 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't log our funky tests
8688 with werror_flag and conftest.err and so forth. This is more
8689 compatible with how _AC_PROG_PREPROC_WORKS_IFELSE behaves,
8690 and anyway the user shouldn't normally want to see this gorp logged.
8691 Problem reported by Ralf Wildenhues.
8692 * lib/autoconf/lang.m4 (AC_LANG_WERROR): werror_flag's default is
8693 empty, not 'no', since the rest of the code uses 'test -z'.

8697 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE):
8698 Use a single call to AC_DO_TOKENS rather than multiple, for
8700 (_AC_LINK_IFELSE): Test that resulting file is executable.
8701 Problem reported by mwoehlke in
8702 <http://lists.gnu.org/archive/html/bug-coreutils/2006-10/msg00048.html>.
8704 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Use "test -x /" rather
8705 than creating a file to use with test -x; this is much faster.
8707 2006-10-02 Bruno Haible <bruno@clisp.org>
8709 * lib/autom4te.in (Automake-preselections): Add
8710 AM_GNU_GETTEXT_INTL_SUBDIR, for automake 1.10.
8712 2006-09-27 Stepan Kasal <kasal@ucw.cz>
8714 * doc/autoconf.texi (Writing testsuite.at): Fix a typo: for

8719 * lib/autoconf/functions.m4 (AC_FUNC_FSEEKO): Don't compile the

8721 * lib/autoconf/specific.m4 (_AC_SYS_LARGEFILE_MACRO_VALUE):
8722 Set cache var to 'unknown' (not 'no') if leaving the macro unset
8723 still doesn't let the program compile.
8724 (AC_SYS_LARGEFILE): Test for _LARGE_FILES only if earlier tests
8727 * lib/autoconf/functions.m4: Fix problems reported by Ralf Wildenhues.
8728 (AC_FUNC_ERROR_AT_LINE): Don't bother to check for error.h. Just
8729 include it, without including anything else.
8730 (AC_FUNC_FSEEKO): Avoid gcc -Wall warnings about constant
8732 (AC_FUNC_STRNLEN): Require AC_USE_SYSTEM_EXTENSIONS.

8749 values. Problem reported by Ralf Wildenhues.

8911 except the first two arguments are reversed.
8912 * doc/autoconf.texi (Caching Results): New macro AC_CACHE_CHECK_INT.
8913 (Generic Compiler Characteristics): AC_COMPUTE_INT no longer

8962 (_AC_PROG_LEX_YYTEXT_DECL): Handle caching correctly; the old code
8963 didn't work if some values were cached but not others. Test for
8964 broken lex libraries like native ia64-hp-hpux11.22; see
8965 <http://sources.redhat.com/ml/binutils/2003-12/msg00337.html>, and
8966 work around the problem by preferring an empty LEXLIB to -lfl or
8967 -ll. Let the user set LEXLIB='' to indicate no library needed.

9119 problems with arg script text that doesn't end in newline, and

9197 * tests/torture.at (Configuring subdirectories): Set CONFIG_SITE
9198 more globally, since the 2006-06-30 patch didn't suffice. Problem
9199 reported by Keith Marshall. Also, don't bother with builddir2,
9200 since it shouldn't be needed any more.
9202 2006-07-07 Paolo Bonzini <bonzini@gnu.org>

9221 2006-07-02 Paul Eggert <eggert@cs.ucla.edu>
9223 * lib/autoconf/types.m4 (AC_TYPE_LONG_LONG_INT):
9224 Require that long long int be at least 64 bits wide. C99 requires
9225 this and enough programs depend on it so we should check for it.
9226 Bruno Haible reports in
9227 <http://lists.gnu.org/archive/html/bug-gnulib/2006-06/msg00286.html>
9228 that long long int is 32 bits wide with some nonstandard compilers.

9239 2006-06-28 Paul Eggert <eggert@cs.ucla.edu>
9241 * doc/autoconf.texi: Be more consistent about using @acronym with
9242 "HP" and "HP-UX". Remove mention of OSF; the old version wasn't
9243 quite right (it talked about "OSF/Tru64", even though the
9244 operating systems were called OSF/1, Digital UNIX, and Tru64 UNIX,
9245 and it even mentioned "OSF 4"!) and at this point there's little
9246 reason to talk about OSF any more, since it died in 1994.
9247 (Specific Compiler Characteristics): Simplify example of
9248 negative-size array.
9249 (File Descriptors): Reorder to make the text flow better.
9250 Remove joke about "appreciate the various levels"; I didn't get it.

9252 <http://lists.gnu.org/archive/html/bug-coreutils/2006-06/msg00225.html>.
9253 (File Descriptors, Limitations of Usual Tools):
9254 Tone down the advice against renaming or removing open files.
9255 (Limitations of Usual Tools): Add a new section, on 'rm'.
9257 2006-06-26 Stepan Kasal <kasal@ucw.cz>
9259 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Use -lX11, not
9260 -lXt in LIBS, idea from Karsten Hopp; this was due since
9263 2005-09-18 Paul Eggert <eggert@cs.ucla.edu>
9264 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Look for X11/Xlib.h
9265 and XrmInitialize rather than X11/Intrinsic.h and XtMalloc
9266 (which belong to Xt, not X itself). See Debian bug 327655.

9306 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Avoid warning
9307 about literal '${datarootdir}' if a definition is found in the
9310 2006-06-20 Paul Eggert <eggert@cs.ucla.edu>
9312 * NEWS: Use "M4" rather than "m4" when appropriate.
9313 Problem reported by Eric Blake.
9314 * doc/autoconf.texi: Likewise.
9315 Use @acronym around BSD, GCC, and GNU when appropriate.
9316 (Why GNU M4): Renamed from "Why GNU m4".
9317 (Redefined M4 Macros): Mention that Posix
9318 m4wrap takes only 1 argument, but GNU M4 1.4.x takes more.
9319 (Buffer Overruns): Mention size_t and ptrdiff_t as alternatives
9322 2006-06-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9324 * bin/autom4te.in (handle_output): Do not forbid the empty
9326 * tests/tools.at (autoconf: the empty token): New test.
9328 2006-06-20 Stepan Kasal <kasal@ucw.cz>
9330 * lib/m4sugar/m4sugar.m4 (m4_init): Merge the two m4_wrap
9331 calls, so that we do not care whether they are LIFO or FIFO;
9332 in the m4_wrap, do not check which diversion is the topmost
9333 one, just check that the stack is balanced at the end.
9334 * lib/m4sugar/m4sh.m4 (AS_INIT): We are going to change the
9335 base diversion forever--pop the previous diversion before
9336 opening the new one; consequently, remove the m4_wrap call.
9337 * lib/autotest/general.m4 (AT_INIT): Likewise.
9338 * tests/m4sugar.at: Do not use
9339 m4_wrap([m4_diversion_pop([..])]), for educational purposes.
9341 2006-06-19 Paul Eggert <eggert@cs.ucla.edu>
9342 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9344 * NEWS: Document that m4wrap/m4_wrap might not be LIFO.
9345 * doc/autoconf.texi (Redefined M4 Macros): Likewise.
9346 Rework example of m4wrap token-pasting trouble so that it doesn't
9347 care whether it's LIFO or FIFO.
9348 Fix some "contrary to"s that are awkward in English.
9350 2006-06-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9352 * lib/autoconf/types.m4 (_AC_TYPE_INT): Set `$ac_cv_c_int$1_t'
9353 to `yes' instead of `int$1_t' if the type is found, for more
9354 consistent configure output (where $1 is the number of bits).
9355 (_AC_TYPE_UINT): Likewise for `uint$1_t'.
9356 Suggested by Bruno Haible.
9358 * lib/autoconf/types.m4 (_AC_TYPE_UNSIGNED_INT): Solaris 2.5.1
9359 needs _UINT8_T and _UINT64_T defines as well, to avoid clashes
9360 with system headers. Report by Bruno Haible.
9362 2006-06-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9364 * config/config.guess, config/config.sub: Sync from upstream.
9366 * bin/Makefile.am (autoconf.in): Use `--melt' for autom4te,
9367 in order to avoid picking up an older installed frozen m4sh.m4f.
9368 Besides an outdated shell startup, this could have been created
9369 by an earlier M4 version with incompatible frozen file format.
9371 2006-06-16 Paul Eggert <eggert@cs.ucla.edu>
9373 * README: Recommend m4 1.4.4 instead of 1.4.3..
9374 * doc/autoconf.texi: Likewise.
9375 (Special Chars in Names): Say that $(.FOO) is portable, as
9376 suggested by Stepan Kasal.
9377 (Installation Directory Variables, Build Directories):
9378 (Automatic Remaking, Subdirectories, Fortran Compiler):
9379 (Making testsuite Scripts, Defining Directories):
9380 Quote variable usages better.
9381 (Making testsuite Scripts): Add clean-local rule to makefile
9382 snippet, by Eric Blake.
9383 (Installation Directory Variables): Fix table item font.
9384 Reword slightly to clarify. Generalize advice about
9385 not using special characters to include all file-related
9386 vars, not just VPATH.
9387 (Special Chars in Variables): Warn about special characters in
9389 (Assignments): Clarify default-value example as suggested by
9391 <http://lists.gnu.org/archive/html/autoconf-patches/2006-06/msg00072.html>.
9392 (Special Shell Variables): Note leading ./ or ../, as suggested
9394 (Limitations of Builtins): Under cd, warn about CDPATH.
9395 (The Make Macro MAKEFLAGS): Untabify. Problem reported by
9398 2006-06-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9400 * doc/autoconf.texi (Configuration Actions): Remove duplicate
9401 `@var', for texi2html.
9402 (Systemology): Some more word wrapping, for DVI output.
9403 (autom4te Invocation): The short option for `--melt' is `-M',
9406 2006-06-15 Paul Eggert <eggert@cs.ucla.edu>
9408 * doc/autoconf.texi: More formatting and English tweaks,
9409 many suggested by Ralf Wildenhues.
9410 Reword to avoid "@code{...}'s" and the like, since it's ugly
9411 with Emacs info mode. discontents -> woes.
9412 Put a few "will"s back. time stamp -> timestamp.
9413 side-effect -> side effect.
9415 2006-06-14 Paul Eggert <eggert@cs.ucla.edu>
9417 * doc/autoconf.texi (Initializing configure, Shell Substitutions):
9418 Warn about $@ not persisting. Problem reported by Julien Danjou in
9419 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=372179>.
9420 (Special Chars in Names): Renamed from Leading _ in Macro Names.
9421 Mention other special chars, too.
9423 2006-06-14 Eric Blake <ebb9@byu.net>
9425 * doc/autoconf.texi (The Make Macro MAKEFLAGS): New node.
9427 2006-06-13 Paul Eggert <eggert@cs.ucla.edu>
9429 * doc/autoconf.texi: Some systematic minor improvements, as
9430 follows. Use "makefile" when talking about makefiles
9431 generally (which might be named "makefile" or "Makefile" or even
9432 "foo.mk"), "Makefile" when talking about a specific makefile
9433 called "Makefile". This unclutters the text from weird quotes
9434 (e.g., "`Makefile's" in info mode). Similarly, use "@var{foo}
9435 values" rather than "@var{foo}s" and similar constructs containing
9436 "}s". Use "Make rules" rather than "Makefile rules". Minor
9437 English-language improvements. Change the prefix "sub-" to "sub"
9439 Put blank lines around examples more consistently.
9440 Avoid "rather" and "very" as intensifiers.
9441 Avoid "will" as an auxiliary.
9442 (Limitations of Make): Split this node into....
9443 (Portable Make, $< in Ordinary Make Rules, Failure in Make Rules):
9444 (Leading _ in Macro Names, Backslash-Newline-Newline):
9445 (Backslash-Newline Comments, Long Lines in Makefiles):
9446 (Macros and Submakes, The Make Macro SHELL, Comments in Make Rules):
9447 (obj/ and Make, make -k Status, VPATH and Make):
9448 (VPATH and Double-colon, $< in Explicit Rules):
9449 (Automatic Rule Rewriting, OSF/Tru64 Directory Magic):
9450 (Make Target Lookup, Single Suffix Rules, Timestamps and Make):
9451 New nodes, resulting from splitup of Limitations of Make.
9452 All cross-references changed. Raise the top node from
9453 a section to a chapter, and all subnodes accordingly.
9454 Redo the introductory wording to match the new organization.
9455 (Installation Directory Variables): Use an example that is
9456 closer to what Autoconf actually does. Mention that VPATH's
9457 value should not contain metacharacters or white space.
9458 (Fortran Compiler): Fix a VPATH bug in an example.
9459 (Leading _ in Macro Names): Mention that this problem is no longer
9460 of practical concern.
9461 (VPATH and Make): Reword the advice to make it clearer
9462 that Autoconf and Automake support VPATH in non-GNU make, but
9463 many packages have bugs in this area.
9464 ($< in Explicit Rules): Refer to Build Directories rather
9465 than using a (non-VPATH-safe) example.
9466 (Automatic Rule Rewriting): Mention the sort of disaster that
9467 can ensue with Solaris-style rule rewriting with VPATH.
9469 2006-06-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9471 * doc/install.texi (Compilers and Options): Weaken the
9472 suggestion to use GNU make for VPATH builds.
9474 * lib/autom4te.in (Automake-preselections): Add AM_PROG_CXX_C_O,
9475 AM_PROG_F77_C_O, AM_PROG_FC_C_O, AC_FC_SRCEXT, AC_FC_FREEFORM.
9477 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Fix M4 quotation
9478 in regular expression.
9480 2006-06-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9482 * doc/autoconf.texi (Installation Directory Variables):
9483 Drop extra @samp from `@table @samp' item.
9484 (Limitations of Usual Tools): Comment fix.
9485 Do not nest @samp just to point to other table items.
9486 (Writing testsuite.at) <AT_CHECK>: The second argument to
9487 `@dvar' is already @samp'ed.
9488 (Making testsuite Scripts) <AC_CONFIG_TESTDIR>: Likewise,
9489 do not use @var in the second argument.
9491 2006-06-07 Paul Eggert <eggert@cs.ucla.edu>
9493 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Look for
9494 $as_shell.exe too. Problem reported by Andreas Buening in
9495 <http://lists.gnu.org/archive/html/autoconf/2006-06/msg00038.html>.
9497 2006-06-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9499 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA): Work around
9500 `unused variable' compiler warning, for `-Wall -Werror'.
9501 Reported by Jaap Haitsma in
9502 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00012.html>.
9504 2006-06-06 Paul Eggert <eggert@cs.ucla.edu>
9506 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Remove core file, in
9507 case the compiler dumps core. Problem reported for
9508 OpenServer 5.0.7 by Tim Rice in
9509 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00019.html>.

9513 2006-06-06 Tim Rice <tim@multitalents.net>.
9515 * lib/freeze.mk: Quiet check-forbidden-patterns so the string
9516 "ERROR" only shows up in "make check" output if there is an
9519 2006-06-06 Eric Blake <ebb9@byu.net>
9521 * tests/tools.at (automatically allowed tokens): Fix typo.
9523 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
9525 * NEWS: Don't blame non-GNU VPATH compatibility issues on Automake.
9527 * doc/autoconf.texi (Integer Overflow): Mention that INT_MIN % -1
9528 typically overflows on x86 CPUs, even though the C standard
9531 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9533 * configure.ac (AC_INIT): Bump to 2.59e.

9540 * config/texinfo.tex: Sync from upstream.
9542 * bin/autoreconf.in: Trace `LT_CONFIG_LTDL_DIR'; if it has been
9543 seen, invoke libtoolize with `--ltdl' argument.
9544 * lib/autom4te.in (Autoreconf-preselections): Adjust.
9546 Suggested by Eric Blake.
9548 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
9550 * NEWS: Whoops! AC_FUNC_STRNLEN isn't obsolescent. Problem
9551 reported by Ralf Wildenhues.

9558 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
9560 * doc/autoconf.texi: Modernize some of the references to Solaris.
9562 2006-06-05 Stepan Kasal <kasal@ucw.cz>
9564 * lib/m4sugar/m4sugar.m4 (m4_require): Modify the error
9565 message issued by AC_REQUIRE.
9566 * tests/m4sugar.at: Check m4_require's error message.
9567 * tests/base.at: Check AC_REQUIRE's error message.
9568 * tests/local.at (AT_CHECK_M4): New macro, almost identical
9570 (AT_CHECK_AUTOM4TE): ... which is now a thin wrapper around
9572 (AT_CHECK_AUTOCONF): Use AT_CHECK_M4; no longer support
9573 `expout' as the last parameter.
9574 * tests/tools.at: Adapt to the above change.
9576 2006-06-04 Stepan Kasal <kasal@ucw.cz>
9578 * doc/autoconf.texi (Limitations of Usual Tools): Correct
9579 information about race-free implementations of mkdir.
9581 2006-06-04 Eric Blake <ebb9@byu.net>

9588 2006-06-04 Paul Eggert <eggert@cs.ucla.edu>
9590 * NEWS: GNU make now recommended for VPATH builds.
9591 Mention that some macros are now documented to be obsolescent.
9592 * doc/autoconf.texi:
9593 Prefer "current" to "modern" to describe
9594 currently-used (albeit perhaps old-fashioned) hosts.
9595 Mention which ancient features no longer need to be worried about.
9596 setgid -> set-group-ID
9597 setuid -> set-user-ID (these are the Posix terms)
9598 Fix some misuses of "only".
9599 (AC_C_BACKSLASH_A, AC_C_CONST, AC_C_PROTOTYPES):
9600 (AC_C_STRINGIZE, AC_C_VOLATILE, AC_FUNC_CLOSEDIR_VOID):
9601 (AC_FUNC_GETPGRP, AC_FUNC_LSTAT, AC_FUNC_MEMCMP):

9608 Mention that these macros are obsolescent.
9609 (Installation Directory Variables): shall -> should
9610 (File Descriptors): Mention that 0, 1, 2 might get reopened.
9611 Mention that it's now safe to use 3 and 4.
9612 (Limitations of Usual Tools): cp -r is now specified by Posix.
9613 Omit longwinded and obsolescent discussion of cp -f.
9614 Modernize discussion of expr, ls.
9615 (Limitations of Make): Modernize discussion of VPATH builds.
9616 Mention $? as a workaround in some cases.
9617 * doc/install.texi (Basic Installation):
9618 Mention "./configure; make; make install" first. Be more
9619 specific about why this file is generic. Remove unnecessary
9620 parens. Remove misleading "only". Remove obsolete advice
9621 about csh. Don't say "configure" takes awhile; say it
9622 might take a while. Suggest CFLAGS=-g rather than CFLAGS=-O2,
9623 and CC=c99 rather than CC=c89, as these are blessed by current
9624 Posix. Recommend GNU make if doing a VPATH build.
9626 2006-06-03 Paul Eggert <eggert@cs.ucla.edu>
9628 * doc/autoconf.texi: Use a consistent style "$ @kbd{...}" for
9629 examples involving shell prompts.

9632 and Paul Eggert <eggert@cs.ucla.edu>
9634 * doc/autoconf.texi (Here-Documents): Add details about the
9635 pre-ksh93g bug. Reword slightly to make it clearer. Consistently
9636 use "here-documents" instead of "here documents".
9638 2006-06-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

9644 * doc/autoconf.texi (File System Conventions): Warn about ":"
9645 anywhere in directory names.
9647 2006-05-31 Paul Eggert <eggert@cs.ucla.edu>
9649 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be even more conservative
9650 about quoting the case statement, just in case.
9651 * doc/autoconf.texi (Here-Documents): Mention that the ksh bug
9652 was fixed in ksh93g; reported by Ralf Wildenhues.
9654 2006-05-31 Stepan Kasal <kasal@ucw.cz>
9656 * doc/autoconf.texi (System Services): Do not document

9666 argument with leading hyphen. Problem reported by Paul Eggert.
9668 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
9670 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be more conservative
9671 about quoting ac_try: quote all of it, if any of it seems suspicious.
9672 This means we don't have to worry about ${ or sed any more.
9673 Also, double-quote the case statement, to work around misuses via
9674 underquoting as reported by Ralf Wildenhues in
9675 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00169.html>.
9676 (_AC_EVAL_STDERR): Revert, since evidently some packages rely on this
9677 undocumented and dangerous macro.

9689 * lib/autoconf/general.m4: Revert AC_TRY_EVAL and AC_TRY_COMMAND,
9690 since evidently some packages rely on the old, broken behavior.
9691 Problem reported by Ralf Wildenhues in
9692 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00160.html>.
9693 (AC_TRY_EVAL, AC_TRY_COMMAND, _AC_EVAL): Go back to the
9694 pre-2006-05-26 definitions, but leave in the comments that
9695 these macros are dangerous and should not be used.
9696 (_AC_DO_ECHO): Renamed from _AC_EVAL_ECHO. All callers changed.
9697 (_AC_DO): Renamed from _AC_EVAL. All callers changed.
9698 (_AC_DO_STDERR): Renamed from _AC_EVAL_STDERR. All callers changed.
9699 (_AC_DO_VAR): Renamed from AC_TRY_EVAL.
9700 (_AC_DO_TOKENS): Renamed from AC_TRY_COMMAND.
9702 2006-05-29 Paul Eggert <eggert@cs.ucla.edu>
9704 * lib/autoconf/status.m4 (AC_OUTPUT_MAKE_DEFS): Rewrite to avoid
9705 the use of 'tr', since this is our only use of 'tr'.
9707 2006-05-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9708 and Paul Eggert <eggert@cs.ucla.edu>
9710 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE):
9711 Don't assume 'grep' works on long lines, since AIX grep doesn't.
9713 2005-05-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9715 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Do not use `grep' on
9716 the output file in the `${datarootdir}' test.
9718 2005-05-28 Stepan Kasal <kasal@ucw.cz>
9719 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9721 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If we have not seen
9722 mention of `datarootdir' in the input file(s), but literal
9723 `${datarootdir}' in the output file, and we haven't warned yet,
9724 then warn as well: the user may have (erroneously) used
9725 `AC_SUBST([mydatadir], [$datadir/my])' instead of the correct
9726 `AC_SUBST([mydatadir], ['${datadir}/my'])'.
9727 * tests/torture.at (datarootdir workaround): Extend this test.
9730 2006-05-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9731 and Paul Eggert <eggert@cs.ucla.edu>
9733 * doc/autoconf.texi (autoheader Invocation): The first argument to
9734 `AC_DEFINE_UNQUOTED' need not be a literal. Mention the
9735 alternatives and clear up the language a bit.
9737 2006-05-27 Paul Eggert <eggert@cs.ucla.edu>
9739 * NEWS: Reword notice for AC_TRY_COMMAND, AC_TRY_EVAL,
9740 ac_config_guess, ac_config_sub, ac_configure.
9741 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
9742 Fix typo that prevented an unnecessary space from being removed.
9743 Problems reported by Ralf Wildenhues in:
9744 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00143.html
9746 2006-05-26 Paul Eggert <eggert@cs.ucla.edu>
9748 * doc/autoconf.texi (Particular Programs, Limitations of Usual Tools):
9749 Use better wording to talk about AC_PROG_MKDIR_P's thread-safety.
9750 Don't use the term "thread-safe" to talk about mkdir race
9751 conditions, since the problem is more a process than a thread
9752 issue. Problem reported by Stepan Kasal in:
9753 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00088.html
9754 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Use code that mimics
9755 the test for 'install' more closely. Look at MKDIR_P first.
9756 Look in the PATH, and at /opt/sfw/bin.
9757 Look for a 'gmkdir' program as well (Solaris 10 /opt/sfw/bin/gmkdir).
9758 Don't bother to try mkdir -p, since we already check mkdir --version;
9759 just look at the version number. (There's no easy way to check
9760 for race-free implementations.)
9761 * tests/tools.at (autoconf: subdirectories): Adjust to above
9762 changes, since MKDIR_P now might end in "/mkdir -p".
9764 * doc/autoconf.texi (autoheader Invocation): Mention that the
9765 first arg of AC_DEFINE_UNQUOTED must be a literal.
9766 Problem reported by Ben Pfaff in
9767 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00090.html>.
9769 * NEWS: Mention that AC_TRY_COMMAND and AC_TRY_EVAL may be removed.
9770 * doc/autoconf.texi (Special Chars in Variables): New section.
9771 (Preset Output Variables): Warn about special chars in CPPFLAGS.
9772 (Installation Directory Variables): Quote $(datadir) better.
9773 (Limitations of Builtins): Describe some of eval's trickiness.
9775 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Simplify quoting.
9776 * lib/autoconf/fortram.m4 (_AC_PROG_FC_V_OUTPUT): Likewise.
9777 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Put leading space
9778 in front of every arg, not just trailing args. Quote apostrophes.
9779 (_AC_EVAL_ECHO): New macro.
9780 (_AC_EVAL, AC_EVAL_STDERR): Use it. Quote arg of eval.
9781 (AC_TRY_EVAL, AC_TRY_COMMAND): Mention that these macros might get
9783 (_AC_LINK_IFELSE): Use proper rule for shell continuation lines,
9784 exposed by quoting of eval argument. Put the command on line line
9786 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): Use eval more safely.
9787 (_AC_PATH_X, AC_PATH_X): Quote more safely.
9788 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Use eval more safely.
9789 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Don't use eval.
9790 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Minor style change.
9791 Handle special chars in prefix, ac_srcdir, ac_aux_dir.
9792 Use eval more safely.
9793 (_AC_OUTPUT_CONFIG_STATUS): Adjust to above changes.
9794 * lib/m4sugar/m4sh.m4 (AS_VAR_GET): Note that this API needs
9796 * tests/base.at (AC_TRY_COMMAND): Use proper rule for shell continuation
9797 lines, exposed by quoting of eval argument.
9799 2006-05-26 Stepan Kasal <kasal@ucw.cz>
9800 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9802 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Drop the
9803 initialization of `ac_cv_exeext', do not override it if it was
9804 already set, unless it was set to `no', for compatibility with
9805 Autoconf-2.13, and comment this.
9806 Do not export `ac_cv_exeext', Libtool hasn't needed this for years.
9807 (_AC_COMPILER_EXEEXT_DEFAULT): Likewise, do not export it.
9808 (_AC_COMPILER_EXEEXT_WORKS, _AC_COMPILER_EXEEXT_CROSS): Typos.
9809 * doc/autoconf.texi (Compilers and Preprocessors) <EXEEXT>:
9810 Document that this test may be overridden by setting
9813 2006-05-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9815 Revert these two patches:
9817 2006-04-06 Eric Blake <ebb9@byu.net>
9818 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_O): Inside cache
9819 check, s/ac_exeext/ac_cv_exeext/. Fixes regression introduced
9822 2006-04-01 Stepan Kasal <kasal@ucw.cz>
9823 Clean up _AC_COMPILER_EXEEXT* macros.
9824 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't try to
9825 detect exeext, it will be done by _AC_COMPILER_EXEEXT_O; just set
9826 ac_file to the name of the default output file and call
9827 _AC_COMPILER_EXEEXT_WORKS. Move the definition of ac_files and the
9828 initial `rm' of the candidate files...
9829 (_AC_COMPILER_EXEEXT): ... here and simplify them. Moreover, use
9830 the same list in subsequent `rm' calls, and for the temporary
9831 redefinition of ac_clean_files; call _AC_COMPILER_OBJEXT at the end,
9832 and don't call the other _AC_COMPILER_EXEEXT_* macros directly, use...
9833 (_AC_COMPILER_EXEEXT_TESTS): ... this new macro.
9834 (_AC_COMPILER_EXEEXT_O): Don't export ac_cv_exeext, it's not needed (or
9835 no longer needed) by libtool. Make it a cache check.
9836 (_AC_COMPILER_EXEEXT_CROSS): Remove the comment, it was obviously
9837 copied here by mistake.
9838 (AC_NO_EXECUTABLES): Redefine _AC_COMPILER_EXEEXT_TESTS, not
9839 _AC_COMPILER_EXEEXT.
9840 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX, AC_PROG_OBJC): Do not call
9841 _AC_COMPILER_OBJEXT directly.
9842 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
9844 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9846 * doc/autoconf.texi (Limitations of Usual Tools) < sed (`t')>:
9847 Fix description of how the buggy `sed' works.
9849 2006-05-25 Noah Misch <noah@cs.caltech.edu>
9853 * lib/Autom4te/XFile.pm (lock): Allow EOPNOTSUPP, besides
9854 ENOLCK. Only mention `make -j' when applicable. Only raise
9855 fatal errors when `make -j' is involved. Improve error message.
9857 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9859 * doc/autoconf.texi (Here-Documents): We now know more about
9860 the variable expansion in here documents bug.
9861 Thanks to Tim Rice and Stepan Kasal.
9863 * doc/autoconf.texi (Making testsuite Scripts): Add an example
9864 how to use TESTSUITEFLAGS. Suggested by Eric Blake.
9866 2006-05-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9868 * tests/autotest.at (Multiline command from M4 expansion):
9869 No failure to be expected if the shell quotes newlines in
9870 commands in the `set -x' output. Report by Tim Rice.
9873 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
9875 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Don't use shell
9876 expansion in the here-documents used by config.status, as that
9877 runs afoul of the Korn shell version M-12/28/93d bug described in
9878 the Autoconf manual, and this in turn causes a Coreutils 5.95 build to
9879 fail as described by Tim Rice and diagnosed by Ralf Wildenhues in
9880 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00082.html>.
9882 2006-05-23 Jim Meyering <jim@meyering.net>
9884 * lib/autoconf/functions.m4 (AC_FUNC_LSTAT_FOLLOWS_SLASHED_SYMLINK):
9885 Fix typo introduced with 2006-04-02 change. It reversed the sense
9888 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
9890 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Simplify ac_dA and
9891 ac_dB slightly, to save bytes in the script.
9892 Max out at 50 lines, rather than 96; this is more likely
9893 (though not guaranteed) to avoid obscure 'sed' failures.
9895 2006-05-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9897 * lib/autotest/general.m4 (AT_INIT): UnixWare `tr' may interpret
9898 `tr -d -' as bad option argument. Work around this by deleting
9899 an unrelated character.
9900 Report by Tim Rice <tim@multitalents.net>.
9902 2006-05-22 Paul Eggert <eggert@cs.ucla.edu>,
9903 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
9904 Stepan Kasal <kasal@ucw.cz>
9906 * doc/autoconf.texi (Particular Programs): Do not promise that
9907 we always prefer the GNU version of the program, and that we
9908 search according to PATH; both rules can have exceptions.
9909 Update description of AC_PROG_GREP, AC_PROG_EGREP, AC_PROG_FGREP,
9910 AC_PROG_SED. Move descriptions of limitations
9911 to the Limitations of Usual Tools section.
9912 (Limitations of Usual Tools) <sed>: Mention script length
9913 limitations with Solaris /usr/ucb/sed.
9914 <grep>: Fix wording for empty alternative. Mention that -c and
9915 -l should not be combined, and that -E and -F should not be
9918 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
9919 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9921 * lib/autoconf/programs.m4 (AC_PROG_SED): Catch script length
9922 limits in Solaris 8 /usr/ucb/sed by testing a long script.
9924 2006-05-22 Stepan Kasal <kasal@ucw.cz>
9926 * doc/autoconf.texi (Defining Symbols): Literal parameter of
9927 AC_DEFINE is now passed to m4_pattern_allow.
9928 * NEWS: Mention that; likewise for AC_SUBST.
9929 * lib/autoconf/general.m4 (AC_DEFINE_TRACE_LITERAL): Pass
9930 the parameter to m4_pattern_allow.
9931 * tests/tools.at: Add a check for that.
9933 2006-05-22 Stepan Kasal <kasal@ucw.cz>
9935 * lib/autoconf/status.m4: Fix typos.
9937 2006-05-21 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9939 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Remove
9940 only the files that this macro generates.
9942 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
9944 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: For
9945 the HP-UX sed limitation of 99 commands, labels do not count.
9946 * lib/autoconf/status.m4 (_AC_SED_CMD_LIMIT): Mention that
9948 (_AC_OUTPUT_HEADER): Revert the change from 2006-05-19.
9950 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
9952 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT):
9953 Import the following fix from coreutils:
9955 2006-01-13 Jim Meyering <jim@meyering.net>
9957 Invoke AC_CHECK_FUNCS(getmntent) unconditionally so that tests of
9958 $ac_cv_func_getmntent (e.g., in gl_LIST_MOUNTED_FILE_SYSTEMS) need
9959 not double-quote uses of that variable, to accommodate the rare
9960 case in which getmntent is available in none of the libraries
9961 checked. This happens at least on FreeBSD 5.0.
9963 2006-05-20 Paul Eggert <eggert@cs.ucla.edu>
9965 * lib/autoconf/general.m4 (AC_CONFIG_AUX_DIRS): Bring back
9966 ac_config_guess, ac_config_sub, and ac_configure, since evidently
9967 some other programs unwisely rely on these undocumented vars.
9968 But put in warning comments about them.
9969 Problem reported by Ralf Wildenhues in
9970 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00068.html>.
9971 * NEWS: Document that these variables are intended to go away.
9973 2006-05-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9975 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): Require AC_PROG_CXX,
9976 and set the language to C++ (analogous to the equivalent Fortran
9979 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): New macro.
9980 * doc/autoconf.texi (C++ Compiler): Document it.
9981 * lib/autoconf/fortran.m4 (_AC_PROG_FC_C_O): Adjust comment.
9984 2006-05-19 Paul Eggert <eggert@cs.ucla.edu>
9986 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Fix off-by-one bug
9987 that caused config.status to generate 100-command sed scripts; the
9988 portable limit is 99.
9990 2006-05-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9992 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Name temporary
9993 variable `ac_d' instead of `d' to avoid infringing namespace.
9994 Report by Ralf Menzel.
9996 2006-05-18 Paul Eggert <eggert@cs.ucla.edu>
9998 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Don't prepend
9999 $ac_top_build_prefix to $MKDIR_P if it's just 'mkdir -p'.
10000 * tests/tools.at (autoconf: subdirectories): New test, taken from
10001 the corresponding problem report by Ralf Wildenhues in:
10002 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00053.html
10004 * lib/autoconf/functions.m4 (AC_REPLACE_FNMATCH, AC_FUNC_FNMATCH_GNU):
10005 Quote some uses of shell variables if they might suffer unexpected
10006 globbing. This doesn't fix all instances of quoting problems that
10007 I found, just the easy ones that look safe.
10008 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR, _AC_INIT_HELP):
10009 (AC_CONFIG_AUX_DIR, AC_CONFIG_AUX_DIR_DEFAULT, AC_CONFIG_AUX_DIRS):
10010 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST, AC_CANONICAL_TARGET):
10011 (AC_CACHE_LOAD, AC_CACHE_SAVE): Likewise.
10012 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF, _AC_PATH_X_DIRECT): Likewise.
10013 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Likewise.
10014 * lib/autoconf/status.m4 (_AC_OUTPUT_LINK, _AC_OUTPUT_SUBDIRS):
10016 * lib/autotest/general.m4 (_AC_INIT_PARSE_ARGS): Likewise.
10017 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Likewise.
10019 2006-05-18 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10021 * bin/autoreconf.in ($help): Reword according to the manual.
10022 Suggested by Olly Betts.
10024 2006-05-17 Olly Betts <olly@survex.com> (tiny change)
10025 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10027 * bin/autoreconf.in: Pass the directory argument to
10028 `require_configure_ac'. Fix comment.
10029 * tests/torture.at (Configuring subdirectories): Expose this.
10030 Reported by Olly Betts.
10032 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10034 * lib/Automake/Configure_ac.pm, lib/Automake/Channels.pm,
10035 lib/Automake/FileUtils.pm, lib/Automake/Struct.pm: Sync from
10036 Automake as follows:
10038 * lib/Autom4te/Configure_ac.pm (find_configure_ac): Use
10039 `$configure_in' instead of `configure.in', to preserve
10040 directory component.
10042 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10044 * config/config.guess, config/config.sub, config/texinfo.tex,
10045 doc/make-stds.texi, doc/standards.texi: Sync from upstream.
10047 2006-05-14 Paul Eggert <eggert@cs.ucla.edu>
10049 * lib/autoconf/headers.m4 (AC_HEADER_STDBOOL): Fix overly-picky
10050 test for C99 conformance; (bool) 0.5 is an integer constant
10051 expression, but (bool) -0.5 is not. Problem reported by Fedor
10052 Sergeev in <http://forum.sun.com/jive/thread.jspa?threadID=96202>.
10054 2006-05-13 Paul Eggert <eggert@cs.ucla.edu>
10056 * doc/autoconf.texi (Particular Programs): AC_PROG_MKDIR_P now
10057 sets MKDIR_P, not mkdir_p, to avoid collisions with Automake.
10058 Warn about obsolete install-sh files. Remove stray sentence
10059 fragment and fix cross reference.
10060 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Don't insist on
10061 install -d; this undoes the 2006-05-10 change.
10062 (MKDIR_P): Mark with AN_MAKEVAR.
10063 (AC_PROG_MKDIR_P): Fall back on $ac_install_sh, not $INSTALL, so
10064 that we don't require $INSTALL to be thread-safe. Move comments
10065 out of generated code. Require AC_CONFIG_AUX_DIR_DEFAULT instead
10066 of AC_PROG_INSTALL. Output a message saying that we're checking
10067 mkdir -p. Set MKDIR_P rather than mkdir_p. Do special magic for
10068 MKDIR_P instead of AC_SUBST.
10069 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE, _AC_OUTPUT_CONFIG_STATUS):
10070 Special magic for MKDIR_P, too.
10071 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Remove comment that defeated
10073 * tests/local.at (AT_CHECK_ENV): mkdir_p -> MKDIR_P.
10075 2006-05-11 Paul Eggert <eggert@cs.ucla.edu>
10077 Sync from Automake, as follows:
10079 2006-05-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10080 * config/install-sh: Initialize IFS, so field splitting isn't
10082 * config/mkinstalldirs: Likewise.
10083 * config/missing: Remove superfluous quotes. Replace all uses of
10084 `[' by `test', for consistency, and for..
10085 * config/missing (sed_minuso, sed_output): New variables.
10086 (autom4te, help2man, makeinfo): Use them. Unifies detection of
10087 `-o FILE', `--output FILE', `--output=FILE', stricter regex.
10088 Fixes `missing' to detect `--output' for help2man. Fixes
10089 PR automake/483. Report by Dennis J. Linse.
10090 (autom4te): Document in `missing --help'.
10092 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
10094 * NEWS: New macro AC_PROG_MKDIR_P. AS_MKDIR_P is now more robust.
10095 * config/install-sh: Don't use 'path' to talk about file names,
10096 as per GNU coding standards. Close a race condition reported by Ralf
10097 Wildenhues and Stepan Kasal. There is still a race condition
10098 on hosts that predate Posix 1003.1-1992, but we can't help this.
10099 Don't mishandle weird characters like space on pre-Posix hosts.
10100 Invoke mkdir at most once per dir arg on pre-Posix hosts.
10101 * doc/autoconf.texi (Programming in M4sh): Cross-reference to
10102 AC_PROG_MKDIR_P from AS_MKDIR_P.
10103 (Limitations of Usual Tools): Cross-reference to AC_PROG_MKDIR_P
10104 from mkdir. Mention that Autoconf 2.60 install-sh is safe but
10105 earlier editions are not (including Automake 1.8.3).
10106 Do not suggest mkinstalldirs for thread-safety.
10107 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Insist on an 'install'
10108 that understands -d, so that AC_PROG_MKDIR_P can fall back on $INSTALL.
10109 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Make it more robust in the
10110 presence of special characters and race conditions.
10111 * tests/local.at (AT_CHECK_ENV): Add mkdir_p to the list of variables
10112 in Autoconf's name space.
10114 2006-05-10 Bruno Haible <bruno@clisp.org>
10115 and Paul Eggert <eggert@cs.ucla.edu>
10117 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): New macro, taken
10118 from Automake with minor changes.
10119 * doc/autoconf.texi (Particular Programs): Document AC_PROG_MKDIR_P.
10121 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
10123 * config/install-sh: Update to Automake CVS version, as follows:
10124 2006-04-25 Stepan Kasal <kasal@ucw.cz>
10125 * lib/install-sh: Simplify the expr implementation of dirname.
10126 2006-04-24 Paul Eggert <eggert@cs.ucla.edu>
10127 * lib/install-sh: Handle --, and diagnose unknown options.
10129 2006-05-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10131 * tests/Makefile.am (AUTOTEST): Use `$(MY_AUTOM4TE)' instead of
10132 `./autom4te' to create `./testsuite', since the `all' target
10133 will ensure its presence, but `installcheck' should not create
10134 the uninstalled wrappers.
10136 * tests/torture.at (Unusual Automake input files): Skip if we
10137 detect automake < 1.8.
10139 2006-05-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10141 * lib/autoconf/c.m4 (AC_PROG_CC_STDC): If ac_cv_prog_cc_stdc
10142 is set to `no', then that overrides and sets ac_cv_prog_cc_c89
10143 and ac_cv_prog_cc_c99 to `no', for backward compatibility.
10146 2006-05-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10148 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Take care not to
10149 munge (multiple) white space and other oddities.
10150 * tests/torture.at (AT_CHECK_AC_ARG_VAR): Make sure to M4-escape
10151 single quotes in variable assignment.
10152 (AC_ARG_VAR, configure invocation): Adjust tests to expose this
10153 and similar failures by adding multiple spaces, tabs, and other
10154 special characters.
10155 Report and different test suggested by Francesco Romani
10156 <fromani@gmail.com> and Andrew Church <achurch@achurch.org>.
10158 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): When we escape
10159 single quotes, we only need to search for single quotes; this
10160 both simplifies the search pattern, and makes us less
10161 susceptible to `echo' variations for arguments not containing
10163 (_AC_ARG_VAR_VALIDATE): Likewise.
10165 2006-05-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10167 * doc/autoconf.texi (Special Shell Variables) <IFS>: Document
10168 `$*' and IFS concatenation issue with traditional shells and
10169 bash-2.04. Report by Seanster@Seanster.com.
10171 2006-05-03 Bruno Haible <bruno@clisp.org>
10173 * doc/autoconf.texi (Limitations of Usual Tools): Identify more
10174 precisely which Mac OS X versions have the od problem.
10176 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
10178 * doc/autoconf.texi: Use @option systematically.
10180 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
10181 and Bruno Haible <bruno@clisp.org>
10183 * doc/autoconf.texi (Limitations of Usual Tools): Add a paragraph
10185 (Integer Overflow): Mention the special case of integer division
10188 2006-05-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10190 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Cater for
10191 traditional shells like the Solaris one that do not use the
10192 first IFS character for assembling `$*'.

10249 * bin/autoconf.as (me): Replace by as_me.
10251 2006-04-25 Paul Eggert <eggert@cs.ucla.edu>
10253 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Don't use AS_ERROR,
10254 since as_me isn't set yet.
10256 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
10258 Prepare for deprecation of AS_BASENAME and AS_DIRNAME, and fix
10259 a few minor bugs in this area.
10261 * doc/autoconf.texi (Programming in M4sh): Comment out the
10262 documentation of AS_BASENAME, for now.
10263 (Shell Substitutions): Do not use AS_DIRNAME in an example.
10264 (Limitations of Builtins) <basename>: Do not refer to
10266 * bin/autoconf.as (me): Don't use AS_BASENAME.
10267 (dir): Remove the unused variable.
10268 * lib/m4sugar/m4sh.m4 (_AS_DETECT_REQUIRED): Renamed from
10269 AS_DETECT_REQUIRED. All uses changed.
10270 (_AS_DETECT_SUGGESTED): Renamed from AS_DETECT_SUGGESTED.
10272 (_AS_DETECT_BETTER_SHELL): Put ;; at the end of a case.

10284 * doc/autoconf.texi (Runtime): Renamed from "Run Time". All uses
10285 of "run time" and "run-time" changed to "runtime", for consistency.
10286 * lib/autoconf/fortran.m4: Likewise (in comment).
10287 * lib/autoconf/functions.m4: Likewise.
10288 * lib/autoconf/general.m4: Likewise.
10289 * lib/autoconf/headers.m4: Likewise.
10291 * doc/autoconf.texi (Run Time): Document the exit status situation
10292 with more accuracy and detail.
10294 2006-04-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10296 * doc/autoconf.texi (Introduction): The GNU Autoconf Macro
10297 Archive is not officially `GNU' any more. Update URL.
10298 (Defining Directories): Likewise
10299 * lib/autoconf/c.m4 (AC_C_RESTRICT): Update URL.
10301 2006-04-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10303 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Remove the leading
10304 newline from the `trap' code to finish `config.log'; the NetBSD
10305 /bin/sh resets the exit status after an empty command, as
10306 documented in doc/autoconf.texi.
10307 Reported by Dalibor Topic <robilad@kaffe.org>.
10309 2006-04-19 Paul Eggert <eggert@cs.ucla.edu>
10311 * doc/autoconf.texi (C Compiler): Clarify AC_C_TYPEOF.
10312 Suggested by Bruno Haible.
10314 2006-04-18 Paul Eggert <eggert@cs.ucla.edu>
10316 * configure.ac (ac_cv_sh_n_works): Don't try to test for it, since
10317 some shells (e.g., Solaris 8 /bin/sh) implement it verrrry slowly.
10318 Instead, just list the shells that we know work.
10319 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Remove 2nd arg. All uses
10320 changed. Be more cautious about the _cv_ variable.
10321 * tests/tools.at (Syntax of the shell scripts): Check the
10322 _cv_ variable once, at first, to avoid an internal autoconf error
10323 when sh -n does not work.
10325 2006-04-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10327 * lib/Autom4te/FileUtils.pm: Sync from Automake.
10329 2006-04-16 Paul Eggert <eggert@cs.ucla.edu>
10331 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Don't
10332 use ">&-" since we're only 99.999% sure that this is portable,
10333 and since the MinGW bug is fixed in a different way.
10334 * lib/autotest/general.m4 (AT_INIT): Likewise.
10336 2006-04-16 Stepan Kasal <kasal@ucw.cz>
10338 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Handle --recheck
10339 before opening config.log, to avoid hitting a bug on MinGW.
10341 2006-04-14 Paul Eggert <eggert@cs.ucla.edu>
10343 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Close
10344 AS_MESSAGE_LOG_FD before reopening it onto the log file.
10345 This works around a MinGW bug reported by Eric Paire.
10346 Make sure that all writes to the log file append to it,
10347 rather than possibly losing data.
10348 * lib/autotest/general.m4 (AT_INIT): Likewise.
10350 2006-04-14 Stepan Kasal <kasal@ucw.cz>
10352 * lib/Autom4te/FileUtils.pm (find_file): Fix a typo in the
10355 2006-04-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10359 * configure.ac (AC_INIT): Bump to 2.59d.
10361 2006-04-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10365 * Makefile.maint (news-date-check): Do not require a leading `*'
10366 before the release date in NEWS.
10368 2006-04-12 Stepan Kasal <kasal@ucw.cz>
10369 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10371 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If the templates for
10372 the instantiated file do not contain the string 'datarootdir'
10373 but contain @datadir@, @docdir@, @infodir@, @localedir@, or
10374 @mandir@, replace the reference '${datarootdir}' by the value.
10375 * tests/torture.at (datarootdir workaround): New test.
10376 * NEWS: Advertise this temporary fixup.
10377 Based on a patch by Bruno Haible, reported and analyzed by
10378 Paul Eggert and Noah Misch.
10380 2006-04-12 Eric Blake <ebb9@byu.net>
10382 * tests/autotest.at (Debugging a failed test): Fix comment.
10384 2006-04-12 Stepan Kasal <kasal@ucw.cz>
10386 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): Simplify the summary of
10387 all the changes since 2006-04-07.
10389 2006-04-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10391 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): If `ln -s file1 file2'
10392 succeeded, but `ln -s file dir' failed, take care to remove the
10393 leftover target before the next test, to prevent its spurious
10394 failure; also make sure `ln file dir' works before selecting it.
10395 Thanks to Keith Marshall for pointing this out.
10398 * lib/autotest/general.m4 (AT_INIT): Store quoted variable
10399 assignments in `at_debug_args', so that we put them correctly
10400 in the `run' script.
10401 * tests/autotest.at (Debugging a failed test): Unmark XFAIL.
10402 Reported by Eric Blake.
10404 2006-04-11 Eric Blake <ebb9@byu.net>
10406 * tests/autotest.at (AT_CHECK_AT): Add new argument, to allow
10407 top-level tests after micro-suite has been run. Used in...
10408 (Debugging a successful test, Debugging script and environment),
10409 (Debugging a failed test): ...these new tests. The first of these
10411 * lib/autotest/general.m4 (_AT_CREATE_DEBUGGING_SCRIPT): New
10412 macro, split out from...
10413 (AT_INIT): ...here, so that using -d also generates a run script.
10414 Document that -d inhibits top-level logging.
10415 * doc/autoconf.texi (testsuite Invocation): Document that -d only
10416 inhibits top-level logging; debug scripts are created.
10418 * lib/autotest/general.m4 (_AT_CHECK): Avoid syntax error on empty
10420 * tests/autotest.at (Empty test, Empty check): New test to check it.
10422 * lib/autoconf/c.m4 (AC_C_CONST, AC_C_VOLATILE): Avoid warnings
10425 2006-04-10 Stepan Kasal <kasal@ucw.cz>
10427 * tests/mktests.sh: Use "trap '' 0", not "trap 0". Do not touch
10428 the files if a problem appears. Make the empty *.at files
10429 read-only, too. Proposed by Ralf Wildenhues.
10431 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10433 * config/Makefile.am: Add comment to force updated Makefile.in.
10435 * lib/freeze.mk: Fix typo in comment. Unlike the last, white
10436 space only patch to this file, this patch causes the Makefile.in
10437 files that include freeze.mk to be updated, and thus have a
10438 newer time stamp again, which in turn makes a pristine CVS
10439 checkout have correct time stamps.
10441 * Makefile.maint (cvs-sv): New macro, to be used..
10442 (config.guess-url_prefix, config.sub-url_prefix)
10443 (texinfo.tex-url_prefix, standards.texi-url_prefix): ..here;
10444 point to CVS text checkout of Gnulib files.
10445 (copyright-check): Bump current year.
10446 (announcement): Do not hard-wire `./announce-gen'.
10447 (cvs-update): Propagate failures of `cvs' and `move-if-change'
10449 * Makefile.cfg (executable-update): Use `chmod a+x' instead of
10451 (wget_files): Update config.guess, config.sub, texinfo.tex by
10452 `wget-update', now that their URLs work again.
10454 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
10456 * doc/autoconf.texi (Particular Types): Don't use AC_CHECK_TYPE.
10457 Problem noted by Paul D. Smith.
10459 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10461 * doc/autoconf.texi: Remove unused words from word list.
10462 * .x-sc_prohibit_atoi_atof, .x-sc_space_tab, .x-sc_sun_os_names,
10463 .x-sc_trailing_space: New files.
10465 * doc/standards.texi: Sync from gnulib.
10467 * NEWS, doc/autoconf.texi (AC_LIBOBJ vs LIBOBJS): Mark
10468 `LIBOBJDIR' as experimental.
10470 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): MSYS `ln -s' fails
10471 with a target directory; it's internally implemented as `cp'
10472 anyway, but since Autoconf advertises the possibility to use
10473 a target directory when LN_S is `ln -s', we need to find out.
10474 Reported by Rolf Ebert <rolf.ebert.gcc@gmx.de> against MSYS,
10475 analyzed by Keith Marshall <keith.marshall@total.com>.
10479 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
10481 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Just output
10482 confdefs.h as-is. In general, if it has backslash-newline or the
10483 like, then it doesn't work either to sort or to remove empty
10486 2006-04-09 Stepan Kasal <kasal@ucw.cz>
10488 * tests/Makefile.am (AUTOCONF_FILES): Fix typo in the comment.
10490 2006-04-09 Alexandre Duret-Lutz <adl@gnu.org>
10492 * lib/autom4te.in (Automake-preselections): Preselect
10495 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>
10497 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Use '\'' for an
10498 apostrophe within a single-quoted string, as this is the usual
10499 tradition and is easier to read than '"'"'. Don't rely on the
10500 shell treating "$/" like '$/'. Use a more-consistent indenting
10501 style for the trap.
10503 2006-04-09 Eric Blake <ebb9@byu.net>
10505 * tests/autotest.at (Backquote command substitution),
10506 (Multiline backquote command substitution): Remove mistaken
10507 AT_NO_CMDSUBST from the 2006-03-14 patch, which was meant to be
10509 (Parenthetical command substitution, Multiline parenthetical
10510 command substitution): here.
10512 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>
10514 Import macros from gnulib (often changing their name).
10516 * NEWS: AC_C_TYPE_LONG_DOUBLE is now obsolete.

10528 (Pointers): Add Gnulib URL.
10529 (Particular Functions): Alphabetize. Add AC_FUNC_STRTOLD.
10530 (Generic Functions): Add AC_CHECK_FUNCS_ONCE. Refer to new
10532 (Particular Headers): Add AC_HEADER_ASSERT. For stdbool.h,

10536 (Generic Declarations): Add AC_CHECK_DECLS_ONCE.
10537 (Particular Structures): Add AC_STRUCT_DIRENT_D_INO,

10542 AC_TYPE_INTMAX_T, AC_TYPE_INTPTR_T, AC_TYPE_LONG_DOUBLE,
10543 AC_TYPE_LONG_DOUBLE_WIDER, AC_TYPE_LONG_LONG_INT, AC_TYPE_UINT8_T,
10544 AC_TYPE_UINT16_T, AC_TYPE_UINT32_T, AC_TYPE_UINT64_T,
10545 AC_TYPE_UINTMAX_T, AC_TYPE_UINTPTR_T, AC_TYPE_UNSIGNED_LONG_LONG_INT.
10546 (C Compiler): Move AC_C_LONG_DOUBLE to ...
10547 (Obsolete Macros): here. Under AC_LONG_DOUBLE, mention
10548 AC_TYPE_LONG_DOUBLE or AC_TYPE_LONG_DOUBLE_WIDER instead.
10549 (Posix Variants): Add AC_USE_SYSTEM_EXTENSIONS.
10550 (Coding Style). Don't mention m4_expand_once.
10551 * lib/autoconf/c.m4 (AC_C_LONG_DOUBLE): Implement via

10558 * lib/autoconf/headers.m4 (AC_CHECK_HEADERS_ONCE): New macro.
10559 (AC_HEADER_ASSERT): New macro.
10560 (AC_HEADER_STDBOOL): Don't assume "#error" works.
10561 Catch a bug in IBM AIX xlc compiler version 6.0.0.0.
10562 Catch a bug in an HP-UX C compiler.
10563 * lib/autoconf/specific.m4 (AC_USE_SYSTEM_EXTENSIONS): New macro.
10564 * lib/autoconf/types.m4 (AC_TYPE_INTMAX_T. AC_TYPE_UINTMAX_T):

10568 (_AC_STRUCT_DIRENT, AC_STRUCT_DIRENT_D_INO, AC_STRUCT_DIRENT_D_TYPE):
10571 * tests/mktests.sh (ac_exclude_list, au_exclude_list): Do not
10572 use /^foo|bar$/, it does not mean /^(foo|bar)$/.
10574 2006-04-08 Stepan Kasal <kasal@ucw.cz>
10576 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Fix the wording
10577 of the warning introduced by the 2001-08-28 change.
10579 2006-04-08 Stepan Kasal <kasal@ucw.cz>,
10580 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10582 * lib/autoconf/general.m4 (AC_CACHE_SAVE): All `ac_cv_env_foo'
10583 variables shall be overriden by the cache.
10584 * tests/torture.at (AC_ARG_VAR): Test also with a first value
10585 that contains braces.
10587 2006-04-07 Stepan Kasal <kasal@ucw.cz>
10589 Revert the patch from 2006-04-01 and only improve
10590 _AS_DETECT_BETTER_SHELL:
10592 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Do not optimize; do not
10593 skip nonexistent directories.
10594 (_AS_DETECT_BETTER_SHELL): The optimization is moved here--try
10595 only shell candidates which exist.
10596 (AS_UNAME): No need to give three parameters to _AS_PATH_WALK.
10597 * lib/autotest/general.m4 (AT_INIT): No need to give three

10645 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): Fix the detection of
10646 whether `set' quotes correctly: redirect stderr of the tested
10647 `set', and use a subshell, for Ultrix; use `sed' instead of
10648 `grep' for zsh `set' which may write binary output; match only
10649 at the beginning of a line, to avoid false positives.
10650 In order to avoid false positives by unrelated variables with
10651 multiline content, put the dump algorithm in a subshell and
10652 unset all variables containing newlines (except some which are
10653 special to the shell). Warn about cache variables that are
10656 2006-04-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

10701 (AC_CONFIG_COMMANDS): Do not do so here.
10702 (_AC_CONFIG_REGISTER_DEST): Double quote the tags in macros _AC_LIST_TAGS
10703 and_AC_LIST_TAG_COMMANDS; fixes another regression introduced by the

10768 * tests/mktests.sh: Don't use 'cat'; just read the files directly.
10769 Prefer 'sort -u' to 'sort | uniq'. Filter data before sorting it.
10770 Use 'comm' rather than N instances of grep; this also fixes a bug
10771 whereby substrings were incorrectly matched, causing us to not
10772 generate tests for AC_F77_NAME_MANGLING and AC_FUNC_LSTAT.
10773 (exclude_list): Exclude empty macros.

10857 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't try to
10858 detect exeext, it will be done by _AC_COMPILER_EXEEXT_O; just set

10861 initial `rm' of the candidate files...
10862 (_AC_COMPILER_EXEEXT): ... here and simplify them. Moreover, use
10863 the same list in subsequent `rm' calls, and for the temporary
10864 redefinition of ac_clean_files; call _AC_COMPILER_OBJEXT at the end,
10865 and don't call the other _AC_COMPILER_EXEEXT_* macros directly, use...
10866 (_AC_COMPILER_EXEEXT_TESTS): ... this new macro.
10867 (_AC_COMPILER_EXEEXT_O): Don't export ac_cv_exeext, it's not needed (or
10868 no longer needed) by libtool. Make it a cache check.
10869 (_AC_COMPILER_EXEEXT_CROSS): Remove the comment, it was obviously
10870 copied here by mistake.

11565 CONFIG_SHELL in the environment of the configure rerun.
11566 * doc/autoconf.texi (Here-Documents, config.status Invocation):
11567 Suggest passing CONFIG_SHELL absolute, and in the environment
11568 rather than as option.
11570 2005-11-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11572 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE):

11588 * lib/autoconf/programs.m4 (AC_CHECK_PROG, AC_PATH_PROG):
11589 Factor functionality to..
11590 (_AC_CHECK_PROG, _AC_PATH_PROG): these new macros, but only
11591 `AC_SUBST($1)' in the public version.
11592 (AC_CHECK_TOOL, AC_PATH_TOOL, AC_PATH_TARGET_TOOL)
11593 (AC_CHECK_TARGET_TOOL): Use internal versions for ac_ct_* and

11613 conftst2.$ac_objext.
11614 * lib/autoconf/fortran.m4 (_AC_PROG_FC_C_O): Likewise.
11616 2005-10-24 Stepan Kasal <kasal@ucw.cz>
11618 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Use conftst2.o instead of
11619 conftest.o, to see whether the compiler really obeys; rm the object
11620 file before and after the test and register it with ac_clean_files.
11621 * lib/autoconf/fortran.m4 (_AC_PROG_FC_C_O): Likewise.
11623 2005-10-21 Stepan Kasal <kasal@ucw.cz>

11641 2005-10-19 Paul Eggert <eggert@cs.ucla.edu>
11643 * doc/autoconf.texi (Generating Sources): AC_LANG_PROGRAMS ->
11644 AC_LANG_PROGRAM, fixing a typo. Don't give details about
11645 the inner workings of AC_LANG_FUNC_LINK_TRY.
11646 * lib/autoconf/c.m4 (AC_LANG_CALL(C)): Reformat to match
11647 AC_LANG_FUNC_LINK_TRY. This involves returning the value returned
11648 by the function rather than ignoring it.
11649 (AC_LANG_FUNC_LINK_TRY(C)): Call the function rather than simply
11650 comparing its address. Intel's interprocedural optimization was
11651 outsmarting the old heuristic. Problem reported by
11654 2005-10-19 Stepan Kasal <kasal@ucw.cz>
11656 * lib/autoconf/general.m4 (AC_SUBST): Remove an obsolete comment.

11663 2005-10-04 Stepan Kasal <kasal@ucw.cz>
11665 * lib/autotest/general.m4 (AT_INIT): Really make the subtree writable
11666 before removing it (chmod -R u+rwx); there are three instances of this.
11668 2005-10-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11669 Stepan Kasal <kasal@ucw.cz>
11671 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Balance parentheses.
11672 * lib/autotest/general.m4 (AT_INIT): If the test dir already exists,
11673 make its content writable before removing it. Remove an errorneous
11674 comment from the end, where the logs of the failed tests are copied
11675 to the main log file.
11677 2005-09-27 Stepan Kasal <kasal@ucw.cz>
11679 * tests/semantics.at (AC_C_BIGENDIAN): Pass --force to autoheader,
11680 in case the computer is too quick. Double quote the configure.ac
11683 * tests/local.at (AT_CHECK_AUTOCONF): Always pass --force to prevent
11684 problems if the testsuite were running too fast.
11686 2005-09-18 Paul Eggert <eggert@cs.ucla.edu>
11688 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Look for X11/Xlib.h
11689 and XrmInitialize rather than X11/Intrinsic.h and XtMalloc
11690 (which belong to Xt, not X itself). See Debian bug 327655.
11691 * NEWS: Mention this.
11693 2005-09-07 Stepan Kasal <kasal@ucw.cz>
11695 * lib/autoconf/c.m4 (AC_LANG_SOURCE(C)): Remove an incorrect comment.
11697 2005-09-06 Paul Eggert <eggert@cs.ucla.edu>
11699 * config/move-if-change: Don't output "$2 is unchanged";
11700 suggested by Ben Elliston. Handle weird characters correctly.
11702 2005-09-06 Stepan Kasal <kasal@ucw.cz>
11704 * lib/autoconf/libs.m4 (AC_SEARCH_LIBS): Merge the two AC_LINK_IFELSE
11705 calls, so that the final expansion of this macro is shorter.
11706 Create the conftest.$ac_ext outside the `for' loop, to speed the run.
11707 Do not use `break' in the argument to AC_LINK_IFELSE, it would skip
11708 the cleanup there. Use AS_VAR_* macros, to be more general.
11709 * tests/semantics.at (AC_SEARCH_LIBS): Check for the cleanup.
11711 * lib/autoconf/general.m4: Use AS_IF where appropriate.
11713 * lib/m4sugar/m4sh.m4 (AS_IF): Use m4_default.
11715 2005-09-01 Stepan Kasal <kasal@ucw.cz>
11717 * doc/autoconf.texi (Configuration Headers): Add an index entry
11720 2005-08-26 Pavel Roskin <proski@gnu.org>

11728 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE):
11729 The previous patch didn't work, so try a better one.
11731 2005-08-26 Stepan Kasal <kasal@ucw.cz>
11733 * doc/autoconf.texi (Programming in M4sh) <AS_TR_CPP>: Fix m4 quoting
11734 in the example. Reported by Bruno Haible.
11735 <AS_TR_SH>: Likewise. Also modify the example to be more convincing:
11736 "if $undefined_var;" succeeds with my shell.
11738 * lib/autoconf/general.m4 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST,
11739 AC_CANONICAL_TARGET): Define by AC_DEFUN, no need to use AC_DEFUN_ONCE;
11740 but change the m4_divert_text to m4_divert_once.
11742 2005-08-25 Paul Eggert <eggert@cs.ucla.edu>
11744 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE):
11745 Work around bug in Solaris /usr/xpg4/bin/awk.
11746 The bug is present in at least Solaris 8 through 10.
11748 2005-08-24 Stepan Kasal <kasal@ucw.cz>
11750 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Simplify; rejecting
11751 some evil values and relying on the fact that $* concatenates the
11752 parameters by the first character from IFS.
11754 2005-08-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
11755 Stepan Kasal <kasal@ucw.cz>
11757 * lib/autoconf/status.m4 (_AC_CONFIG_REGISTER_DEST): When the
11758 first header appears, define AH_HEADER.
11759 * doc/autoconf.texi (Configuration Headers): Document AH_HEADER.
11760 Update limitations about when to call AC_CONFIG_HEADERS.
11761 (Configuration Commands): Document that AC_CONFIG_COMMANDS_PRE
11762 parameter can call AC_SUBST, AC_DEFINE, or AC_CONFIG_FOOS; explain
11763 that AC_CONFIG_COMMANDS_PRE and AC_CONFIG_COMMANDS_POST are not
11764 ``Configuration Actions''; fix their index entries.
11766 * lib/autotest/general.m4 (AT_INIT): Process multiple keywords
11767 options correctly. Process N-M as M-N if M is smaller than N.
11768 Process ranges correctly so that N-N will run only N.
11769 Sort and uniquify the tests that will be run. If there is more
11770 than one test, reinsert the banners for the tests.
11771 * tests/autotest.at (Keywords): Unmark XFAIL.
11773 2005-08-23 Stepan Kasal <kasal@ucw.cz>
11775 * lib/autoconf/general.m4 (_AC_DEFINE_Q): Strip the parameter list
11776 before passing the macro name to AH_TEMPLATE.
11778 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): config.status
11779 now opens log after option processing; in particular, --version
11780 and --help do not touch config.log.
11782 * Makefile.maint: Revert the change from 2005-08-12.
11784 2005-08-22 Stepan Kasal <kasal@ucw.cz>
11786 * lib/autoconf/general.m4 (AC_ARG_ENABLE, AC_ARG_WITH): Factor out

11797 Prepend to LIBS, not append, in examples.
11799 2005-08-16 Stepan Kasal <kasal@ucw.cz>
11801 When building in place, set srcdir="."; suggested by Tim Van Holder.
11803 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Do this; to recognize
11804 build in place, we need ac_pwd, and thus have to AC_REQUIRE ...
11805 (_AC_INIT_DIRCHECK): ... this macro and AC_DEFUN both of them.
11806 * lib/autoconf/status.m4 (_AC_SRCDIRS): Fix a comment: srcdir="."
11807 does not mean "no --srcdir option".
11809 2005-08-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11811 * tests/autoscan.at (autoscan): New file.
11812 * tests/suite.at: Use it.
11813 * tests/Makefile.am (TESTSUITE_HAND_AT): Add it.
11814 Reported against Libtool by Gideon Go <gideon.go@gmail.com>.
11816 * tests/autotest.at (Keywords): Test keywords combinations.
11818 2005-08-12 Stepan Kasal <kasal@ucw.cz>
11820 * Makefile.maint (GZIP_ENV): When checking the help text of gzip,
11821 add "2>&1"; gzip 1.2.4 prints help on stderr.
11823 2005-07-27 Stepan Kasal <kasal@ucw.cz>
11825 * lib/autotest/general.m4 (_AT_DECIDE_TRACEABLE): The symbol at_reason
11826 was pushdef'ed twice while popped only once. Push it only once.
11827 (_AT_CHECK): Cosmetic changes to the "case $at_status" command.
11829 2005-07-26 Stepan Kasal <kasal@ucw.cz>
11831 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): The message is now

11834 2005-07-25 Paul Eggert <eggert@cs.ucla.edu>
11836 * Makefile.maint: Update from Bison.
11838 * lib/m4sugar/m4sugar.m4 (m4_strip): Comment fix---change tab to
11839 "<tab>" in comment, so that the point is understandable.
11841 2005-07-25 Stepan Kasal <kasal@ucw.cz>
11843 Rewrite substantial part of lib/autoconf/status.m4.
11844 The main change is that CONFIG_FILES, CONFIG_HEADERS, CONFIG_LINKS,
11845 and CONFIG_COMMANDS are not processed in four separate loops.
11846 Instead, there is one main loop. This alows that the common code
11847 is expanded only once, thus config.status (and configure) is smaller.
11849 The registration mechnism in AC_CONFIG_FILES and cousins also changed;
11850 the AC_LIST_FILES and cousins macros are no longer used.
11852 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES, _AC_OUTPUT_HEADERS,
11853 _AC_OUTPUT_LINKS, _AC_OUTPUT_COMMANDS): Renamed to ...
11854 (_AC_OUTPUT_FILE, _AC_OUTPUT_HEADER, _AC_OUTPUT_LINK,
11855 _AC_OUTPUT_COMMAND): ..., respectively. These macros no longer
11856 contain the initialization, nor the for loop, nor the associated
11857 commands; all these go to ...
11858 (_AC_OUTPUT_MAIN_LOOP): ... this new macro, called from
11859 _AC_OUTPUT_CONFIG_STATUS.
11860 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST, _AC_CONFIG_SPLIT_FILE_IN):
11861 Nuked; the code was merged into _AC_OUTPUT_MAIN_LOOP.
11862 (_AC_OUTPUT_FILE): The creation of the sed script ...
11863 (AC_OUTPUT): ... and the setup of ac_vpsub goes to ...
11864 (_AC_OUTPUT_FILES_PREPARE): ... a new macro, also called from
11865 _AC_OUTPUT_MAIN_LOOP.
11866 (_AC_CONFIG_FILES, _AC_CONFIG_HEADERS, _AC_CONFIG_LINKS,
11867 _AC_CONFIG_COMMANDS): Use ...
11868 (_AC_CONFIG_FOOS): ... this new macro, which uses these ...
11869 (_AC_CONFIG_REGISTER, _AC_CONFIG_REGISTER_DEST): ... new macros.
11870 (_AC_CONFIG_FILE, _AC_CONFIG_HEADER, _AC_CONFIG_LINK,
11871 _AC_CONFIG_COMMAND, _AC_CONFIG_DEPENDENCIES): No longer needed.
11872 (_AC_CONFIG_DEPENDENCY): Update, it uses these ...
11873 (_AC_CONFIG_DEPENDENCY_DEFAULT, _AC_FILE_DEPENDENCY_TRACE_COLON):
11875 (_AC_CONFIG_UNIQUE): Update.
11876 (AC_LIST_FILES, AC_LIST_HEADERS, AC_LIST_LINKS, AC_LIST_COMMANDS):
11877 Replaced by this ...
11878 (_AC_LIST_TAGS): ... new common macro.
11879 (AC_LIST_FILE_COMMANDS, AC_LIST_HEADER_COMMANDS, AC_LIST_LINK_COMMANDS,
11880 AC_LIST_COMMAND_COMMANDS): Replaced by this ...
11881 (_AC_LIST_TAG_COMMANDS): ... new common macro.
11882 (_AC_CONFIG_COMMANDS_INIT): Moved top to the `registration' section;
11883 this didn't belong to the `config commands' section.
11884 (_AC_OUTPUT_COMMANDS_INIT): Don't initialize, m4_ifdef is our friend.
11885 (AC_CONFIG_COMMANDS_PRE, AC_OUTPUT_COMMANDS_PRE,
11886 AC_CONFIG_COMMANDS_POST): Moved to a new section, these didn't belong
11887 to the `config commands' section either.
11888 (AC_CONFIG_SUBDIRS): Don't touch diversion DEFAULTS.
11889 (_AC_LIST_SUBDIRS): Don't initialize, m4_ifdef is our friend.
11891 ... and many changes to the comments nearby.
11893 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): At the end of the day,
11894 set ac_subdirs_all='_AC_LIST_SUBDIRS'.
11895 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
11896 AC_CONFIG_COMMANDS(command:input,...) is no longer allowed.
11897 (#define header templates): The comment at the top of the generated
11898 header now includes the name(s) of the source file(s).
11900 Several unrelated small changes:
11902 * lib/autoconf/general.m4 (AC_CACHE_VAL): Be didactic, quote the first
11903 parameter to AC_DIAGNOSE.
11904 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS): Likewise.
11905 (_AC_LINK_FILES_CNT): Don't AU_DEFUN this; it causes confusing messages
11906 with autoupdate; use m4_define_default inside AU_DEFUNed AC_LINK_FILES.
11907 (AC_OUTPUT): In the compatibility code, use m4_ifvaln, to be consistent
11908 with AU::AC_OUTPUT.
11909 (AU::AC_OUTPUT): Don't double-quote $2 and $3, the compatibility code
11910 in AC_OUTPUT doesn't double-quote it either.
11911 * tests/tools.at (autoupdate): AU::AC_OUTPUT no longer double-quotes the
11914 2005-07-10 Stepan Kasal <kasal@ucw.cz>
11916 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Document which
11917 versions of Portland Group compiler produce single- and double-quoted
11918 -cmdline argument. Reported by Steven G. Johnson <stevenj@fftw.org>
11919 and Ole Holm Nielsen <Ole.H.Nielsen@fysik.dtu.dk>.
11921 2005-07-07 Paul Eggert <eggert@cs.ucla.edu>
11923 * tests/local.at (AT_CONFIG_CMP): Ignore lines like "LIBS=''" too.
11924 This is a corrected version of yesterday's patch.
11926 2005-07-07 Stepan Kasal <kasal@ucw.cz>
11928 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Report the full
11929 path, too; insert a "===" to emphasize the line.
11931 * lib/autoconf/general.m4 (AC_CANONICAL_BUILD): Rename
11932 ac_cv_build_alias to ac_build_alias.
11933 (AC_CANONICAL_HOST, AC_CANONICAL_TARGET): Simplify.
11935 On 2005-02-24, an unintentional AC_SUBST([CC]) was introduced; this
11936 change eliminates it. Problem reported by Alexandre Duret-Lutz.
11937 * lib/autoconf/general.m4 (_AC_ARG_VAR_PRECIOUS): Move the AC_SUBST ...
11938 (AC_ARG_VAR): ... here.
11939 (_AC_INIT_PREPARE): Call AC_SUBST for build_alias, host_alias and
11942 Keep a list of all precious variables and process them with one simple
11943 for loop, instead of expanding all commands, or, OTOH, complicated
11944 processing of output of "set".
11945 * lib/autoconf/general.m4 (_AC_ARG_VAR_PRECIOUS): Acumulate the
11946 variable names in new macro...
11947 (_AC_PRECIOUS_VARS): ... which will be assigned to ac_precious_vars.
11948 (_AC_ARG_VAR_STORE): New macro which writes to diversion PARSE_ARGS
11949 a loop to assign all ac_env_* and ac_cv_env_* variables.
11950 (_AC_ARG_VAR_VALIDATE): Use shell variable ac_precious_vars, divert
11952 (_AC_INIT_DEFAULTS): At the end, if _AC_PRECIOUS_VARS is set, assign
11953 its value to shell variable ac_precious_vars and call
11954 _AC_ARG_VAR_STORE and _AC_ARG_VAR_VALIDATE.
11955 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Don't call
11956 _AC_ARG_VAR_VALIDATE.
11958 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Move AC_LANG_PUSH(C)
11959 and the AC_SUBSTs ...

11979 2005-07-05 Stepan Kasal <kasal@ucw.cz>
11981 Fix my changes from 2005-07-01; reported by Noah Misch.
11982 * lib/autoconf/status.m4 (_AC_CONFIG_DEPENDENCIES): Fix the
11983 description, the macro now accepts only a single tag.
11984 (_AC_CONFIG_UNIQUE): Likewise; s/AC_File/[$1]/
11986 Fix cases when the varsions of Autoconf and Autotest don't match.
11987 Reported by Noah Misch.
11988 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Set also
11989 at_top_builddir, for compatibility with older autotest.
11990 * lib/autotest/general.m4 (AT_INIT): If at_top_build_prefix
11991 is not set, use at_top_builddir, for compatibility with older
11992 versions of autoconf.
11994 2005-07-04 Paul Eggert <eggert@cs.ucla.edu>
11996 * bin/autom4te.in ($m4): Catch usages like --nesting-limit=2048.
11997 Problem reported by Patrick Welche.
11999 2005-07-03 Paul Eggert <eggert@cs.ucla.edu>
12001 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Use &, not |, in
12002 sed substitution command, so that we allow | in program prefixes
12003 and program suffixes. (& is a problem anyway; we're not fixing
12005 * lib/autoconf/status.m4 (AC_CONFIG_FILES): Likewise, for
12006 configure_input, top_builddir, srcdir, etc.
12007 * lib/autotest/general.m4 (AT_INIT): Likewise, for

12010 2005-07-02 Alexandre Duret-Lutz <adl@gnu.org>
12012 * lib/autoconf/general.m4 (AC_SITE_LOAD): Rewrite the
12013 for loop over config.site files using `set', to allow
12014 directory names containing IFS characters.
12016 2005-07-01 Paul Eggert <eggert@cs.ucla.edu>
12018 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Remove the tests for
12019 directories with weird names. Apparently some people like living
12020 on the edge. However, improve the test that "pwd" actually does
12021 report a name for the working directory.
12022 * NEWS: Remove the claim that we test for funny chars in dir names.
12024 2005-07-01 Stepan Kasal <kasal@ucw.cz>

12038 (Limitations of Usual Tools) <sed>: Another minor rephrasing.
12040 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Use a here
12041 document to output the default config_* lists to config.status.
12042 Don't recognize option --file, if the functionality is not there.
12043 Likewise for --header; moreover, recognize --he and --h as shortcuts
12044 for --help in that case.
12046 * lib/autoconf/status.m4: Fix the order of the "sections", so that it
12047 matches the order of execution. No code changed.

12066 * lib/autoconf/general.m4 (AC_ARG_VAR): Move next to _AC_ARG_PRECIOUS.
12068 * lib/autoconf/general.m4 (AC_SUBST_TRACE): New macro, to be traced
12069 instead of AC_SUBST; proposed by Alexandre Duret-Lutz.
12070 (AC_SUBST): Call it.
12071 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Call AC_SUBST_TRACE for
12072 the directory specific variables; but don't call it for configure_input.
12074 2005-06-28 Derek Price <derek@ximbiot.com>
12076 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: Reword recent
12079 2005-06-23 Paul Eggert <eggert@cs.ucla.edu>
12081 * NEWS: Don't worry about spaces in bindir etc. Only srcdir and working
12082 directory have inherent problems with special characters like spaces,
12083 due to limitations in Make syntax. Problem reported by Alexandre
12085 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Implement the above.
12086 Also, fix Tru64 porting problem with shell patterns,

12097 Fix some more shell quoting problems. Prompted by a bug report
12098 from Justace Clutter.
12099 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Put name of invalid
12100 variable into diagnostic. Make the diagnostic an error, not a warning,
12101 because we really don't support spaces and suchlike in dir names.
12102 (_AC_INIT_SRCDIR): Allow special characters in $ac_unique_file.
12103 Don't worry about backslashes in srcdir; it can't happen now.
12104 (_AC_INIT_PARSE_ARGS): Allow weird characters in ac_optarg.
12105 Simplify ac_optarg handling.
12106 (_AC_ARG_VAR_VALIDATE): Remove unnecessary and inconsistent quotes.

12112 * tests/atlocal.in: Propagate $EGREP and $SED.
12113 * tests/local.at (AT_CHECK_ENV): Use $EGREP, not $GREP -E.
12114 (AT_CONFIG_CMP): Use sed instead of grep plumbing.
12116 * doc/autoconf.texi (Limitations of Usual Tools) <grep>: Mention
12117 that '\|' is not allowed in BREs; recommend using newline separated
12118 list of patterns instead of multiple -e options.
12120 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Remove an old comment.
12122 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Use AC_SUBST/2.

12128 2005-06-21 Stepan Kasal <kasal@ucw.cz>
12130 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: Document that
12131 b, t, r, w commands require single space, while : cannot have any.
12132 (Special Shell Variables): Fix sed code this in the example.
12133 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Likewise; and fix a typo.
12134 * lib/autotest/general.m4 (AT_ARG_OPTION): Fix typo in the description.
12136 * lib/m4sugar/m4sugar.m4 (m4_split): If the parameter is empty,
12137 expand to the empty list. Don't use two pairs of m4_changequote,
12138 it's not necessary.
12140 2005-06-20 Derek Price <derek@ximbiot.com>
12142 * lib/m4/programs.m4 (AC_PROG_YACC): Declare YACC & YFLAGS precious.
12144 2005-06-17 Paul Eggert <eggert@cs.ucla.edu>
12146 * lib/m4sugar/m4sh.m4 (as_awk_strverscmp): Port to Solaris /bin/awk.
12147 * doc/autoconf.texi:
12148 Don't mention Solaris versions so much, if a
12149 problem is common to all extant versions of Solaris. Say "SunOS
12150 4" instead of "SunOS" for SunOS 4.
12151 (awk): Mention more of the limitations of traditional Awk.
12152 (cat): Don't talk about cat -v.
12154 2005-06-16 Paul Eggert <eggert@cs.ucla.edu>
12156 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE): New macro.
12157 (AS_VERSION_COMPARE): New macro. The API is taken from CVS,
12158 but the implementation is entirely different and is designed
12159 to be compatible with glibc strverscmp.
12160 * tests/m4sh.at (AS_VERSION_COMPARE): New test.
12162 * doc/autoconf.texi (Limitations of Usual Tools): Mention expr bug

12165 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT):
12166 Use shell builtins rather than 'expr', to work around expr bug.
12168 2005-06-10 Paul Eggert <eggert@cs.ucla.edu>
12170 * doc/autoconf.texi: "filesystem" -> "file system".
12171 "behaviour" -> "behavior".
12172 Warn about \(...\)* in Solaris sed (written by Ralf Menzel).
12173 * lib/autoconf/general.m4: Omit blank after ":" sed command,
12175 * lib/m4sugar/m4sh.m4: Likewise.
12176 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Work around problem
12177 with Solaris sed. Fix by Ralf Menzel and Stepan Kasal.
12179 * man/Makefile.am (MOSTLYCLEANFILES): Add $(srcdir)/*.t.
12180 (.x.1): Ignore the time stamp in the .TH line when deciding whether
12181 to update the man page. That way, we don't have to check in new
12182 man pages every month.
12184 * lib/m4sugar/m4sh.m4 (AS_VAR_TEST_SET): Work even if $1 contains
12185 quotes and backslashes. Patch from Derek Price.
12187 2005-06-10 Derek Price <derek@ximbiot.com>
12189 * doc/autoconf.texi (Programming in M4sh): Document AS_TR_CPP &

12194 * lib/autotest/general.m4 (AT_INIT): Don't accept Solaris 9's diff
12195 -u, since it outputs chatter if the input files are the same.
12196 Problem reported by Ralf Menzel.
12198 2005-06-08 Derek Price <derek@ximbiot.com>
12200 * lib/m4sugar/m4sugar.m4: Undefine include & sinclude rather than
12201 renaming them since they are about to be redefined anyhow.
12203 2005-06-08 Derek Price <derek@ximbiot.com>
12205 * doc/autoconf.texi (Redefined M4 Macros): Add index entries for most
12206 redefined M4 macros to this node. Document m4_include & m4_sinclude.
12207 Move m4_undefine to alphabetical order.
12209 2005-06-07 Paul Eggert <eggert@cs.ucla.edu>
12211 * README: Recommend GNU M4 1.4.3 or later.
12212 * doc/autoconf.texi (Introduction): Likewise.
12213 Reword to avoid some formatting glitches.
12214 Use "#!/bin/sh", not "#! /bin/sh"; the space isn't needed these days.
12215 Clarify explanation of HP compiler bug.
12216 Redo example output tp match current CVS snapshot.
12217 Use @example.org in email addresses when the examples
12218 might get inadvertently cut-and-pasted into user code.
12219 Remove example of autom4te usage that doesn't seem to work now.
12220 Use modern AC_INIT (except when the example is meant to be
12221 shown with Autoconf 2.13).
12222 Update ksh info for Solaris 9 and later.
12224 Modernize description of Automake versions a bit.
12225 Don't claim a future version of Autoconf is near.
12226 * doc/install.texi: Reword to avoid some formatting glitches.
12228 2005-06-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
12230 * doc/autoconf.texi: Add [] to examples, so that the manual
12231 follows its own advice about quoting better.
12232 Reword to avoid some formatting glitches.
12233 * doc/installt.exi: Reword to avoid some formatting glitches.
12235 * doc/autoconf.texi (Limitations of Builtins) <case>: Mention
12236 Tru64 ksh pattern matching bug. Reported against Libtool by
12237 Albert Chin <libtool@mlists.thewrittenword.com> and
12238 Nicolas Joly <njoly@pasteur.fr>.
12240 2005-06-06 Stepan Kasal <kasal@ucw.cz>
12242 m4_cdr of one-member list was [[]] (one-member list containing an
12243 empty string) instead of [] (an empty list. Callers were skewed to
12244 match this misbehaviour. As a consequence of this:
12245 - m4_foreach([x], [], [foo]) expanded to `foo', while
12246 - the expansion of m4_foreach([x], [[]], [foo]) was empty.
12247 This bug has been fixed:
12249 * lib/m4sugar/m4sugar.m4 (m4_cdr): If only one argument is given,
12250 expand to an empty string; print error msg if called without
12252 (m4_foreach, m4_map, m4_map_sep): Don't expect the previous
12253 misbehaviour; handle [] and [[]] correctly.
12255 2005-06-06 Stepan Kasal <kasal@ucw.cz>
12257 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Nuke ac_max_here_lines.
12258 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Simplify the sed
12259 scripts created and the loop applying them, use _AC_SED_CMD_LIMIT.
12261 2005-06-06 Ralf Menzel <menzel@ls6.cs.uni-dortmund.de> (trivial change)
12263 * doc/autoconf.texi (Limitations of Usual Tools): Solaris' awk cannot
12264 swallow records with more than 99 fields.
12265 * lib/autotest/general.m4 (AT_INIT): Use the awk builtin `split' to
12266 parse the long line.
12268 2005-06-04 Stepan Kasal <kasal@ucw.cz>
12270 * doc/autoconf.texi (Limitations of Usual Tools): AIX awk cannot
12271 swallow literals longer than 399. Reported by Ralf Wildenhues.
12272 * lib/autotest/general.m4 (AT_INIT): Pass $at_groups though stdin,
12273 to workaround this limitation.
12275 2005-06-03 Steven G. Johnson <stevenj@alum.mit.edu>
12277 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Find g95 in addition
12278 to gfortran, and make these the first two compiler names
12279 checked (following the general autoconf preference for gcc).
12281 2005-06-03 Stepan Kasal <kasal@ucw.cz>
12283 * tests/Makefile.am (check_SCRIPTS): Set to $(wrappers).
12284 (DISTCLEANFILES): Remove $(check_SCRIPTS).

12287 2005-06-02 Paul Eggert <eggert@cs.ucla.edu>
12289 * lib/autotest/general.m4 (AT_INIT): Don't create a regular
12290 expression of unbounded size when processing the --list
12291 option. This runs afoul of a limit of 399 bytes per regular
12292 expression on AIX. Problem reported by Ralf Wildenhues.
12294 2005-06-01 Paul Eggert <eggert@cs.ucla.edu>

12297 * doc/autoconf.texi (Particular Headers): Reword example
12298 for multiline stdbool replacement.
12299 (Setting Output Variables): Reword text a bit. Don't
12300 give all the details about |#_!!_#|.
12301 Reword description of line replacement.
12303 2005-05-31 Dan Manthey <dan_manthey@partech.com>
12305 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Output variables may
12306 now contain newlines, and substituted files must be referenced on
12307 a line alone; the sed scripts to substitute them are now very
12309 (_AC_SED_CMD_LIMIT): Added; single place to store limit on how many
12310 commands can be put in a sed script portably.
12311 * doc/autoconf.texi (Setting Output Variables): Document above
12312 changes. (Particular Header Checks) <AC_HEADER_STDBOOL>: Give exaple
12313 use of multiline substitution.

12319 From Ralf Menzel (trivial change).
12321 2005-05-25 Paul Eggert <eggert@cs.ucla.edu>
12323 * tests/local.at: Don't attempt to check for negated character
12324 classes in shell scripts. The test was too brittle.
12326 2005-05-25 Stepan Kasal <kasal@ucw.cz>
12328 * bin/autoconf.as: Don't use "shift 2"; it's not portable enough.
12329 * doc/autoconf.texi (Limitations of Builtins): Document this
12332 2005-05-24 Stepan Kasal <kasal@ucw.cz>
12334 * lib/m4sugar/m4sh.m4 (_AS_ECHO_LOG): New macro to factor out

12339 * lib/m4sugar/m4sugar.m4 (m4_ifset): Use m4_ifval.
12341 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Merge the two error
12342 messages when ac_unique_file is not found.
12343 (AC_CONFIG_MACRO_DIR): Simplify the `if' at the end.
12344 (AC_MSG_CHECKING, AC_MSG_RESULT): Put braces around the two echo
12345 commands, for consistency with AC_MSG_ERROR and such.
12347 * bin/autoconf.as: Make more use of "shift 2" in option processing.

12357 2005-05-20 Stepan Kasal <kasal@ucw.cz>
12359 * NEWS: @top_builddir@ is now a dirname, ac_top_builddir will follow.
12360 * lib/autoconf/status.m4 (_AC_SRCDIRS): Rename ...
12361 (ac_top_builddir): ... this ...
12362 (ac_top_build_prefix): ... to this; the old name is also kept, for
12363 backward compatibility.
12364 (ac_top_builddir_sub): New variable, without the trailing slash,
12366 (_AC_OUTPUT_FILES): s/@top_builddir@/$ac_top_builddir_sub/
12367 * doc/autoconf.texi (Configuration Actions): Rename
12368 ac_top_builddir to ac_top_build_prefix.

12380 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Don't m4_quote the second
12381 argument to m4_foreach. I guess it was necessary in the past,
12382 but I think it's a no-op now.
12384 2005-05-17 Stepan Kasal <kasal@ucw.cz>
12386 * lib/autoconf/general.m4 (_AC_INIT_HELP): Merge two consecutive
12387 ``cat <<_ACEOF'' commands to one.
12388 (_AC_CANONICAL_SPLIT): Use expr, not ``echo|sed.''
12389 * lib/autoconf/status.m4: On various places, use expr instead of
12391 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST):
12392 (_AC_CONFIG_SPLIT_FILE_IN): New macros, to factor out common code.

12395 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Use awk to search for
12396 the wrong patterns between ``case'' and ``esac.'' The previous
12397 code had false positives.

12463 2005-05-10 Paul Eggert <eggert@cs.ucla.edu>
12465 * doc/autoconf.texi (Autoconf Language): Be more precise about
12466 quoting rules. Problems noted by Stepan Kasal.
12467 Also, throughout this document, be more careful about white space.
12468 "blank", "white space", and "space" all have different meanings
12469 and we should be careful to say what we mean.

12499 * doc/autoconf.texi (Autoconf Language): Add more description
12500 about quoting heuristics.
12501 (Limitations of Builtins): Describe "set -" problems.
12503 2005-04-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
12505 * lib/autotest/general.m4 (AT_KEYWORDS): Separate by space,
12508 * doc/autoconf.texi (External Software): Replace AC_DEFINE_UNQUOTED
12509 by AC_DEFINE; it was a mistake.
12510 From bug reported against libtool by Dalibor Topic <robilad@kaffe.org>.
12512 2005-04-25 Stepan Kasal <kasal@ucw.cz>
12514 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): A tiny optimization.
12516 2005-04-22 Stepan Kasal <kasal@ucw.cz>
12518 * doc/autoconf.texi (External Software): Quadrigraphs are not
12519 processed correctly in AS_HELP_STRING; avoid this in the examples.
12520 * lib/m4sugar/m4sh.m4 (AS_HELP_STRING): Add a FIXME about quadrigraphs.
12521 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Likewise; and rephrase the
12522 comment and reduce m4_default([foo], []) to [foo].
12523 (m4_strip): Update the explanation.
12525 2005-04-19 Paul Eggert <eggert@cs.ucla.edu>
12527 * lib/autoconf/general.m4 (_AC_INIT_PREPARE, _AC_RUN_IFELSE):
12528 Remove core.conftest.* too; it's generated by Tru64 5.1.
12529 Problem reported by Jennis Pruett.
12530 * lib/autoconf/functions.m4
12531 (AC_FUNC_SETVBUF_REVERSED, AC_FUNC_UTIME_NULL):
12532 Don't bother to remove core files; AC_RUN_IFELSE should do that
12535 2005-04-19 Stepan Kasal <kasal@ucw.cz>
12537 * lib/m4sugar/m4sugar.m4 (m4_bpatsubsts): Add the b- to comment, too.

12559 2005-04-10 Paul Eggert <eggert@cs.ucla.edu>
12561 * doc/autoconf.texi (Particular Functions): Use gnulib's current

12579 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS):
12580 Merge `-z option' as well for the benefit of Solaris link flags. Pass
12581 whole-archive (-zallextract, -zdefaultextract) options in the hope of
12582 unique libraries, for the Sun Fortran 95 8.0 compiler. Bug reported
12583 against Libtool by Yury Puhalsky <pooh@cryptopro.ru>.
12585 2005-03-22 Paul Eggert <eggert@cs.ucla.edu>
12587 * NEWS: The configure command now warns you if you attempt to use
12588 a directory whose name contains a special character like space,
12590 * doc/autoconf.texi (Installation Directory Variables): Allow
12591 "," in file names. Do not use \@; it's not a portable regexp.
12592 * bin/Makefile.am (edit): Likewise.
12593 * lib/Makefile.am (edit): Likewise.

12603 (_AC_INIT_SRCDIR): Use ac_pwd rather than invoking pwd.
12604 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Propagate
12605 ac_pwd, and quote srcdir.
12606 * lib/autotest/general.m4 (AT_INIT): Quote file name args.
12608 * doc/autoconf.texi: Fix some systematic formatting problems.
12609 ".)" needs a following @: if not at the end of a sentence, and
12610 similarly for "!)". "etc." should be preceded by a comma.
12611 "n-th" -> "@var{n}th". pdksh is still buggy, so update its date.
12613 2005-03-22 Bruno Haible <bruno@clisp.org>
12615 * doc/autoconf.texi (Input): Mention that AC_CONFIG_AUX_DIR's
12616 argument is often called 'build-aux'.
12618 2005-03-07 Stepan Kasal <kasal@ucw.cz>
12620 * doc/autoconf.texi (Quotation Rule Of Thumb): Mention that the
12621 macro AC_TRY_LINK is obsolete.
12622 (Installation Directory Variables): Change `AC_OUTPUT_FILES' to
12625 2005-02-24 Stepan Kasal <kasal@ucw.cz>
12627 * lib/autoconf/c.m4 (AC_PROG_CC): Be more careful to skip
12628 `/usr/ucb/cc'; use `cl.exe' to distinguish the MS compiler
12629 from a Common Lisp's `cl'.
12630 (AC_PROG_CXX): Behave according to the documentation: don't
12631 search for $ac_tool_prefix$CCC and $CCC, just set CXX=$CCC;
12632 make the variable CCC precious; use `cl.exe', not `cl'.
12634 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
12635 Alexandre Duret-Lutz <adl@gnu.org>
12637 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin from
12638 /dev/null, as "configure" shouldn't read stdin, and this insulates
12639 us from problems (e.g., when testing for "cl"). Also, do this
12640 redirection before invoking "hostname" or "uname", and keep the
12641 original input stream available via...
12642 (AS_ORIGINAL_STDIN_FD): ... this new macro.
12643 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't
12644 bother with "</dev/null" since it's now done at the top of

12653 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
12655 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N_PREPARE): Don't set ECHO_C to
12656 newline if neither \c nor -n work, as that would output two
12657 newlines. Prefer -n to \c. Reported by Stepan Kasal.
12659 2005-02-12 Stepan Kasal <kasal@ucw.cz>
12661 * lib/m4sugar/m4sh.m4 (AS_IF): Define by m4_defun, not m4_define.
12662 This causes that any required macros inside will get before the if.
12663 * doc/autoconf.texi (autom4te.cache): A typo.
12665 2005-02-12 Paul Eggert <eggert@cs.ucla.edu>
12667 Undo previous change, except keep the change to
12668 lib/autoconf/programs.m4 that replaced grep with shell
12669 pattern-matching. This is because net-snmp configure reads stdin.
12670 Reported by Noah Misch.
12672 2005-02-11 Paul Eggert <eggert@cs.ucla.edu>
12674 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin
12675 from /dev/null, as "configure" shouldn't read stdin, and this
12676 insulates us from problems (e.g., when testing for "cl").
12677 Suggested by Alexandre Duret-Lutz. Also, do this redirection
12678 before invoking "hostname" or "uname".
12679 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
12680 _AC_LINK_IFELSE): Undo previous change, as it's no longer needed.
12681 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Don't bother with
12682 "</dev/null" since it's now done at the top of 'configure'.
12683 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
12684 * lib/autoconf/programs.m4 (_AC_PATH_PROG_FLAVOR_GNU): Likewise.
12685 Also, replace grep with shell pattern-matching, to save a process.
12687 2005-02-10 Paul Eggert <eggert@cs.ucla.edu>
12689 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
12690 _AC_LINK_IFELSE): Redirect stdin to /dev/null, in an attempt to
12691 avoid thinking that Allegro Common Lisp's "cl" command is a C++
12694 2005-02-09 Paul Eggert <eggert@cs.ucla.edu>
12696 * doc/autoconf.texi (Limitations of Usual Tools): Document that
12697 grep -q isn't portable. Improve grep -s explanation.
12698 Problem reported by Dan Manthey.
12700 2005-02-08 Paul Eggert <eggert@cs.ucla.edu>
12702 * doc/autoconf.texi (Special Shell Variables): Clarify
12703 PATH_SEPARATOR wording; fix typo in IFS. Reported by Gary V. Vaughan.
12705 2005-02-07 Paul Eggert <eggert@cs.ucla.edu>
12707 * doc/autoconf.texi: Use @acronym for DJGPP.
12708 Fix some @code's that should have been @env's, and vice versa.
12709 Sort environment variable names.
12710 Mention that shells no longer inherit IFS.
12711 Don't recommend PATH_SEPARATOR=';' so strongly.
12712 Mention that $RANDOM might expand to the empty string.
12713 "symlink" and "soft link" -> "symbolic link".
12714 Improve mktemp description (reported by Bruno Haible).
12716 2005-02-05 Paul Eggert <eggert@cs.ucla.edu>
12718 * tests/foreign.at (Libtool): Don't overquote AT_SETUP arg.
12719 * tests/m4sh.at (AS_DIRNAME, AS_BASENAME, AS_MKDIR_P, AS_HELP_STRING):

12724 2005-02-04 Paul Eggert <eggert@cs.ucla.edu>
12726 * NEWS: Mention AT_COPYRIGHT.
12728 * tests/local.at (AT_CMP): Use diff directly on input files rather
12731 * lib/autoconf/programs.m4 (AC_PROG_SED): Don't look in
12732 /usr/xpg4/bin since that sed dumps core (at least on Solaris 8).

12744 * lib/m4sugar/m4sugar.m4 (m4_re_string, m4_re_word): Revert 2002-03-04.
12745 * tests/local.at (AT_CHECK_M4SUGAR): Add `m4sugar' to keywords.
12746 (AT_CHECK_ENV): Ignore LTLIBOBJS, FC variables, EGREP, FGREP, and SED.

12752 CPPFLAGS to `configure' instead of setting it in `configure'.
12754 * lib/m4sugar/m4sh.m4 (AS_UNAME): Try only /usr/bin/hostinfo, not
12755 any `hostinfo' in $PATH, since hostinfo.exe is a popular file name

12789 * lib/m4sugar/m4sugar.m4 (m4_re_escape): Escape ?, ^, \, $ too;
12790 this fixes a bug tickled by the AT_CAPTURE_FILE change noted below.

12793 2047-byte limit on line length of portable text files.
12794 * lib/autoconf/general.m4 (AC_SUBST, AC_SUBST_FILE):
12795 Use newline as a separator, not space.

12808 * doc/autoconf.texi (Special Shell Variables): Mention _,
12809 BIN_SH, DUALCASE. Say that variables other than "status" are safe
12810 if they contain a lower-case letter. The DUALCASE problem was
12811 reported by Ralf Wildenhues.

12821 Unicos 9 sed limitations.
12822 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Try cf77 before fort77
12823 to get the option-enhanced interface on older Crays. Try ftn for

12826 2005-02-01 Paul Eggert <eggert@cs.ucla.edu>
12828 * man/Makefile.am (.x.1): Go back to the simple solution, but take
12829 care to echo the commands, so the user knows what's going on.
12830 Modified from a suggestion by Stepan Kasal.

12853 Simplify the implementation of m4_require (a.k.a. AC_REQUIRE).
12854 Update the long comment explaining it.
12856 m4_require no longer writes an ``is required by'' line to the
12857 execution stack. It contains only one bit of non-redundant
12858 information: that the macro was required, not called. And even
12859 this bit is useless in most situations: have you ever met a macro
12860 which both calls and requires the same macro?
12862 * lib/m4sugar/m4sugar.m4 (_m4_defun_pro): Don't push a diversion...
12863 (_m4_defun_pro_outer): ... only via this macro, for the outermost
12865 (_m4_defun_epi, _m4_defun_epi_outer): Complementarily.

13282 * lib/autoconf/functions.m4 (AC_FUNC_MEMCMP): Use
13283 "char c = '\200';" rather than "char c = 0x80;" as the

13348 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Don't check
13349 the $1_found variable, don't test whether the file is executable;
13350 Both things are checked ...
13351 (_AC_PATH_PROG_FEATURE_CHECK): ... here; AS_EXECUTABLE_P replaces
13352 the former ``test -f''.
13353 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Fix a typo.
13355 2004-11-10 Paul Eggert <eggert@cs.ucla.edu>

13387 (AU_DEFUN): Use it to fix the bug when the index contained AC_AU_DEFUN.
13388 Problem reported by Stepan Kasal.
13390 2004-09-05 Paul Eggert <eggert@cs.ucla.edu>
13392 Fix problems reported by Andreas Buening in:

13394 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Set SHELL=/bin/sh
13396 * lib/autotest/general.m4 (AT_INIT): Don't assume /dev/null is
13397 readable; it's not true in OS/2-emx.
13399 2004-09-04 Paul Eggert <eggert@cs.ucla.edu>
13401 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): If xmkmf returns
13402 "/usr/include", clear ac_x_includes instead of leaving it as "no"
13403 (trivial change). Problem and patch reported by Andrew Church in:
13404 http://lists.gnu.org/archive/html/bug-autoconf/2004-04/msg00016.html
13406 2004-09-03 Paul Eggert <eggert@cs.ucla.edu>

13434 texinfo.tex for now (done by hand now).
13435 * Makefile.maint (wget_files, cvs_files):
13436 Remove ansi2knr.c; nobody uses it.
13437 (ansi2knr.c-url_prefix): Remove.
13438 (cvs-update): Fix test for failure. I don't know why it ever
13441 * doc/autoconf.texi: Update URLs, some of which went stale.
13442 Use @uref rather than @href.
13444 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Have configure
13445 handle "--" as per POSIX. Suggested by Paul Pogonyshev.
13447 * config/config.guess, config/config.sub, config/elisp-comp,
13448 config/install-sh, config/mkinstalldirs, config/texinfo.tex,
13449 doc/fdl.texi, doc/standards.texi: Sync with master copy.

13458 tests/tools.at, tests/torture.at:
13459 Use "file name" rather than "filename" or "path",
13460 to be consistent with the terminology of the GNU coding standards.
13462 2004-08-19 Paul Eggert <eggert@cs.ucla.edu>
13464 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C),
13465 AC_C_LONG_DOUBLE): Undo 2004-06-04 change, as it didn't work with
13466 HP-UX 11.23 cc/aCC or Tru64 4.0 cc. Problem reported by Noah Misch in
13467 <http://lists.gnu.org/archive/html/autoconf/2004-07/msg00004.html>.
13469 More fixes to support spaces in the name of the build directory.
13470 This isn't a complete fix but it's an improvement.
13472 * bin/autoconf.as (autom4te_options): New var.
13473 Use it instead of appending to AUTOM4TE, so that we can allow
13474 spaces in the build directory's absolute name.
13475 * bin/autoheader.in ($autoconf): Allow spaces in file names.
13476 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP, _AT_CHECK,
13477 AT_CHECK_NOESCAPE): Likewise.
13478 * tests/wrapper.as (testdir, AUTOM4TE_CFG, autom4te_perllibdir,

13489 * doc/autoconf.texi (Function Portability): Document isinf and
13490 and isnan. From a suggestion by Kevin Ryde.
13492 * lib/Autom4te/General.pm (END): Return correct exit status even
13493 if unlink succeeds and sets $?. Needed with Solaris 8's perl 5.00503.
13495 2004-08-09 Paul Eggert <eggert@cs.ucla.edu>
13497 * tests/torture.at (Deep Package): Use configure.in, not configure.ac,
13498 for compatibility with Automake 1.4. Reported by J C Fitzgerald in
13499 <http://lists.gnu.org/archive/html/bug-autoconf/2003-08/msg00051.html>.
13501 2004-08-04 Alexandre Duret-Lutz <adl@gnu.org>
13503 * lib/autoconf/general.m4 (AC_REQUIRE_AUX_FILE): New empty macro.
13504 (AC_CANONICAL_BUILD): Call it to require config.sub and config.guess.
13505 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Likewise for install-sh.
13506 * doc/autoconf.texi (Input): Document AC_REQUIRE_AUX_FILE.
13507 * lib/autom4te.in (Automake-preselections): Preselect
13508 AC_REQUIRE_AUX_FILE. Automake 1.10 will trace it.
13510 2004-08-02 Alexandre Duret-Lutz <adl@gnu.org>
13512 * lib/autom4te.in (Automake-preselections): Preselect
13513 AC_CANONICAL_BUILD and AC_CANONICAL_TARGET. Automake 1.9.1 will
13516 2004-07-29 Paul Eggert <eggert@cs.ucla.edu>

13521 Document problem with "`""`" in pdksh POSIX mode.
13523 2004-07-27 Paul Eggert <eggert@cs.ucla.edu>
13525 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): Use "set -o posix"
13526 with pdksh, too. Problem reported by Patrick Welche via
13528 * doc/autoconf.texi (Shellology): Note that set -o posix is
13529 useful for pkdsh, too.
13531 2004-06-24 Paul Eggert <eggert@cs.ucla.edu>
13533 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Require
13534 _AS_UNSET_PREPARE, so that we can use $as_unset directly.
13535 Don't fail if ENV or BASH_ENV is readonly.
13536 (AS_SHELL_SANITIZE): Don't fail if ENV, MAIL, MAILPATH, LC_ALL,
13537 etc. are read only. Problem reported by Ludovic Courtes.
13539 2004-06-23 Noah Misch <noah@cs.caltech.edu>
13541 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): If the shell is
13542 zsh, disable GLOB_SUBST to avoid backslash handling problems.
13545 2004-06-04 Paul Eggert <eggert@cs.ucla.edu>
13547 * doc/autoconf.texi (File System Conventions): Warn about
13548 names like "aux". Problem reported by Eric Blake.
13550 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY (C)): Use division
13551 by zero instead of array size, so that we can use any arithmetic
13552 constant expression (instead of requiring an integer constant
13553 expression). This allows us to test expressions like DBL_MAX <
13554 LDBL_MAX, which didn't conform to the C standard using the old
13556 (AC_C_LONG_DOUBLE): Put back in the tests for LDBL_MAX and LDBL_EPSILON,
13557 now that we can do floating-point tests at compile time.
13559 2004-06-02 Paul Eggert <eggert@cs.ucla.edu>
13561 * lib/autoconf/c.m4 (AC_C_LONG_DOUBLE): Don't check LDBL_MAX
13562 and LDBL_EPSILON, as the resulting expression isn't an
13563 integer constant expression and violates the C standard.
13564 Problem reported by Nelson H. F. Beebe. Also, check
13565 for "L" suffix, and check that long double doesn't have
13566 worse range or precision than double, that mixed-mode
13567 arithmetic doesn't generate a diagnostic, that double
13568 constants fit in long double.
13570 2004-06-03 Kevin Ryde <user42@zip.com.au>
13572 * doc/autoconf.texi (Function Portability): Add notes on free(NULL),
13573 malloc(0) and realloc(NULL,size).
13575 * doc/autoconf.texi (Shell Substitutions): Spelling error reported by
13578 2004-05-31 Paul Eggert <eggert@cs.ucla.edu>
13580 * lib/autoconf/headers.m4 (HAVE_STDBOOL_H): Detect _Bool bug
13581 in HP aC++/ANSI C B3910B A.05.55 [Dec 04 2003]. Problem reported
13584 2004-05-26 Paul Eggert <eggert@cs.ucla.edu>
13586 * doc/autoconf.texi (Limitations of Builtins): Mention that ! COMMAND
13587 can be rewritten using if-then-else. Suggested by Bruno Haible.
13589 2004-05-25 Paul Eggert <eggert@cs.ucla.edu>
13591 * doc/autoconf.texi (testsuite Scripts): Fix typo.
13592 Problem reported by Stepan Kasal.
13594 2004-05-24 Paul Eggert <eggert@cs.ucla.edu>
13596 * tests/Makefile.am (autoconfdir): Fix to match comment (trivial
13597 change). Patch reported by Ralf Wildenhues in
13598 <http://mail.gnu.org/archive/html/bug-autoconf/2004-05/msg00092.html>.
13600 * lib/autoconf/functions.m4 (AC_FUNC_MBRTOWC): Don't assume that a
13601 function F exists if the compiler and linker let you compile an
13602 expression like (F != 0). Recent versions of GCC optimize away
13603 the reference to F in that case, since every function address must
13604 be nonzero, so the link succeeds even if F does not exist.
13605 Problem reported by Manu in
13606 <http://mail.gnu.org/archive/html/bug-gnu-utils/2004-05/msg00060.html>.
13608 * doc/autoconf.texi (Systemology): Standardize on the spelling of
13609 "Unix". Many uses changed.
13610 (Limitations of Builtins): Explain better why the ! command isn't
13613 2004-05-22 Alexandre Duret-Lutz <adl@gnu.org>
13615 * lib/autom4te.in (Automake-preselections): Preselect
13616 LT_SUPPORTED_TAG in lieu of AC_LIBTOOL_TAGS.
13618 2004-05-19 Kevin Ryde <user42@zip.com.au>
13620 * doc/autoconf.texi (Function Portability): Add strerror_r, cross
13621 referencing AC_FUNC_STRERROR_R.
13623 * doc/autoconf.texi (Particular Functions): In AC_FUNC_CLOSEDIR_VOID,
13624 note pessimistic assumption when cross compiling.
13626 2004-05-16 Paul Eggert <eggert@cs.ucla.edu>
13628 * doc/autoconf.texi (Limitations of Make): Note that BSD make
13629 (until 2004) invoked subcommands with sh -e, contra POSIX.
13630 Reported by Kevin Ryde.
13632 2004-05-10 Eric Sunshine <sunshine@sunshineco.com>
13634 * programs.m4 (_AC_PROG_GREP): Fixed bug where PATH argument handed to
13635 _AC_PATH_PROG_FEATURE_CHECK contained leading whitespace (i.e.
13636 " $PATH:/usr/xpg4/bin"). This resulted in bogus tests, such as
13637 `test -f " /usr/bin/grep"', which _always_ failed.
13638 (AC_PROG_SED): Ditto bogus PATH fix.
13639 * autoconf.texi (AC_PROG_GREP): Properly document that this macro
13640 requires that grep correctly supports _multiple_ `-e' options, rather
13641 than stating only that grep should accept `-e'.
13643 2004-05-03 Paul Eggert <eggert@cs.ucla.edu>
13645 Port to C99, which requires that 'exit' be declared.
13647 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Use AC_INCLUDES_DEFAULT
13648 to ensure that stdlib.h is included.
13649 * lib/autoconf/functions.m4 (_AC_LIBOBJ_ALLOCA, AC_FUNC_SETPGRP,
13650 AC_FUNC_STRTOD, AC_FUNC_SETVBUF_REVERSED, AC_FUNC_FORK, _AC_FUNC_FORK,
13651 _AC_FUNC_VFORK, AC_FUNC_WAIT3): Likewise.
13652 * lib/autoconf/specific.m4 (AC_SYS_RESTARTABLE_SYSCALLS): Likewise.
13653 * lib/autoconf/types.m4 (AC_TYPE_GETGROUPS): Likewise.
13654 * lib/autoconf/headers.m4 (AC_HEADER_STDC): Include <stdlib.h>
13655 when using 'exit' in a test; C99 requires that 'exit' be declared.
13657 2004-05-02 Paul Eggert <eggert@cs.ucla.edu>
13659 * doc/autoconf.texi (Particular Programs): AC_PROG_GREP
13660 now prefers 'grep' implementations that accept -e.
13661 (Limitations of Usual Tools): Describe problems of traditional
13662 egrep and fgrep with long input lines, and of traditional grep
13664 * lib/autoconf/programs.m4 (AC_PROG_GREP): Check for -e, too.
13665 (_AC_PROG_GREP): Assume 3rd arg is properly quoted for the shell.
13666 All callers changed. Append /usr/xpg4/bin to the PATH, for
13668 (_AC_FEATURE_CHECK_LENGTH): Discard stderr, so we don't bother
13669 the user with complaints about multiple -e options.
13670 * tests/local.at (AC_STATE_SAVE): Use $GREP, not grep.
13671 Define it with AC_PROG_GREP.
13672 * configure.ac (AC_PROG_GREP): Add.
13673 * lib/freeze.mk (GREP): New macro.
13675 2004-05-02 Eric Sunshine <sunshine@sunshineco.com>
13677 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Consult $SHELL as
13678 a possible candidate only after all others fail, rather than
13679 consulting it first. This improves backward compatibility by
13680 better reflecting the way shell selection occurred in previous
13681 versions of Autoconf, and should help to avoid triggering latent
13682 problems in other packages, such as the one in Automake where zsh
13683 is not handled robustly:
13684 http://mail.gnu.org/archive/html/automake/2004-04/msg00095.html
13685 Although it is not Autoconf's responsibility to work around
13686 problems in Automake, it nevertheless makes sense to avoid
13687 introducing unnecessary incompatibilites.
13689 2004-04-22 Albert Chin-A-Young <china@thewrittenword.com>,
13690 Gary V. Vaughan <gary@gnu.org>
13692 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Don't guess
13693 how deeply nested we are when a suitable tool is found, set the
13694 ac_path_TOOL_found flag.
13695 (_AC_PATH_PROG_FEATURE_CHECK): Encapsulate knowledge of how deeply
13696 nested we are in this macro. Break out of all 3 nested loops if
13697 ac_path_TOOL_found is set.
13699 2004-04-21 Gary V. Vaughan <gary@gnu.org>
13701 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Break out
13702 of the _AS_PATH_WALK loop too if GNU flavor is found.
13704 2004-04-21 Alexandre Duret-Lutz <adl@gnu.org>
13706 * doc/autoconf.texi (Limitations of Make): Update documentation
13707 for `$<'. New entry `Long lines', based on a report from Simon
13708 Josefsson. Augment the documentation for SHELL = @SHELL@ with a
13709 paragraph about DJGPP, based on a mail from Richard Dawe.
13711 2004-04-20 Paul Eggert <eggert@twinsun.com>
13713 * tests/c.at (C keywords): Don't assume that GCC supports
13714 "restrict" and "inline", as sufficiently-old GCC versions do not
13715 (also, GCC configured to be in pedantic C89 mode does not).
13716 Problem reported by Sumit Pandya in:
13717 http://mail.gnu.org/archive/html/autoconf/2004-04/msg00092.html
13719 * lib/autoconf/c.m4 (_AC_PROG_CC_G, _AC_PROG_CXX_G): Don't
13720 consider -g to work if it generates warnings when plain compiles
13721 don't. Problem reported by Braden McDaniel in:
13722 http://mail.gnu.org/archive/html/autoconf-patches/2003-07/msg00014.html
13724 * doc/autoconf.texi (Slashes): New section, to document a problem
13725 reported by Jim Meyering in:
13726 http://mail.gnu.org/archive/html/bug-coreutils/2004-02/msg00060.html
13728 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Remove potential
13729 linker output files before linking, to work around IRIX 6 linker bug.
13730 Problem reported by Rainer Orth in:
13731 http://mail.gnu.org/archive/html/autoconf-patches/2004-02/msg00007.html
13733 2004-04-20 Gary V. Vaughan <gary@gnu.org>
13735 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Make the
13736 best tool so far counter rely on the tool path variable name to
13737 avoid checks for one tool being affected by the results of running
13738 the length check on a previous tool.
13740 * lib/autoconf/programs.m4 (_AC_PROG_GREP): Take an additional
13741 match expression argument, as different greps have different
13742 regular expression flavours.
13743 (AC_PROG_FGREP): Pass 'FGREP'. fgrep treats all match chars as
13745 (AC_PROG_EGREP): Pass 'EGREP$'.
13746 (AC_PROG_GREP): Pass 'GREP$'.
13748 2004-04-20 Albert Chin-A-Young <china@thewrittenword.com>
13750 * lib/autoconf/programs.m4 (AC_PROG_GREP): Cache variable
13751 is `ac_cv_path_GREP', not `oc_cv_path_GREP'.
13753 2004-03-29 Paul Eggert <eggert@twinsun.com>
13755 * doc/autoconf.texi (Particular Headers, Particular Types, Generic

13869 * bin/Makefile.am ($(srcdir)/autoconf.in): Depend on

13878 AC_SUBST provides no portable way to escape literal newlines.
13880 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS): Ignore all
13881 flags of the form -lcrt*.o, not just -lcrt[01].o and -lcrtbegin.o.
13882 Darwin uses -lcrt2.o and there's little point to cataloging all
13883 the system variants. Partial fix reported by Andreas Waechter in:

13909 Paul Eggert <eggert@twinsun.com>
13911 * lib/m4sugar/m4sh.m4 (M4SH-SANITIZE): New diversion.

13926 trigger the bash bug anymore.
13927 * lib/autotest/general.m4: Document M4SH-SANITIZE, do not
13928 use AS_INIT_WITH_SHELL_FN.
13929 * bin/autoconf.in, tests/wrapper.in: Regenerated.

13961 the 2003-05-22 change, which removed the older years from the list.
13962 * lib/autoconf/status.m4 (AC_OUTPUT): Update copyright date to 2004.

13975 _AC_PROG_GREP, and AC_PROG_SED.

14006 2004-01-26 Paul Eggert <eggert@twinsun.com>
14008 * doc/autoconf.texi (Default Includes): Include <stdint.h> even if
14009 HAVE_INTTYPES_H is defined. This is needed on Tru64 5.1b with
14010 Compac C V6.5-207 (dtk), which defines uintmax_t in <stdint.h> but
14011 not <inttypes.h>. Problem reported by Tim Mooney in
14012 <http://mail.gnu.org/archive/html/bug-coreutils/2004-01/msg00147.html>.
14013 * lib/autoconf/headers.m4 (_AC_INCLUDES_DEFAULT_REQUIREMENTS):
14016 * lib/autoconf/programs.m4 (AC_PROG_SED): Use diff, not sed;
14017 otherwise "make check" fails because it forbids cmp (I guess
14018 because cmp treats files as binary on DOS-like systems).
14020 * tests/mktests.sh: Update copyright date to 2004, since some tests
14021 have changed in 2004.
14023 2004-01-23 Gary V. Vaughan <gary@gnu.org>

14026 non-truncating sed or gsed program in PATH.
14027 * tests/acprograms.at: Add it.

14031 2004-01-15 Paul Eggert <eggert@twinsun.com>
14033 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Try -std, not -std1, since
14034 -std1 disables some useful extensions on Tru64. Problem reported
14035 by N. Lichtmaier in
14036 <http://mail.gnu.org/archive/html/autoconf/2004-01/msg00100.html>.
14038 2004-01-14 Paul Eggert <eggert@twinsun.com>
14040 * doc/autoconf.texi (Programming in M4sh): Document that
14041 AS_MKDIR_P succeeds if the destination is a symbolic link
14042 to an existing directory.
14043 (Limitations of Usual Tools): Note that mkdir -p might not
14044 succeed on symlinks to directories.
14046 2004-01-13 Paul Hilfinger <hilfinger@CS.Berkeley.EDU>
14048 * lib/autoconf/autoupdate.m4 (AU_DEFUN): Grammar fix in comment.
14049 * bin/autoheader.in: Grammar fix in message.
14050 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P):
14051 Test for dir before calling mkdir -p. (trivial changes)

14058 2004-01-10 Jim Meyering <jim@meyering.net>

14062 2004-01-09 Paul Eggert <eggert@twinsun.com>
14064 * lib/autoconf/general.m4: Fix bug: AC_CHECK_SIZEOF evokes a warning
14065 with `autoconf -Wall,error'. Bug reported by Eric Blake in:
14066 http://mail.gnu.org/archive/html/autoconf-patches/2004-01/msg00000.html
14067 (_AC_COMPUTE_INT_COMPILE): Invoke _AC_COMPILE_IFELSE, not
14068 AC_COMPILE_IFELSE, since we now assume our caller invokes
14069 AC_LANG_COMPILER_REQUIRE, for symmetry with _AC_COMPUTE_INT_RUN.
14070 (_AC_COMPUTE_INT_RUN): Likewise, for _AC_RUN_IFELSE instead
14071 of AC_RUN_IFELSE; this avoids the warning mentioned above.
14072 (_AC_COMPUTE_INT): Invoke AC_LANG_COMPILER_REQUIRE.
14074 2004-01-07 Paul Eggert <eggert@twinsun.com>
14076 * lib/autoconf/general.m4 (_AC_LIBOBJS_NORMALIZE): Avoid \$ inside
14077 `"'...'"`, as it's confusing (and I suspect it may not work on
14078 some platforms). The code was incorrect anyway, as it assumed
14079 that \$ evaluated to itself in that context. Reported by
14080 Alexandre Duret-Lutz.
14082 2004-01-07 Alexandre Duret-Lutz <adl@gnu.org>
14084 * lib/autom4te.in (Automake-preselections): Preselect AC_LIBTOOL_TAGS
14085 and _LT_AC_TAGCONFIG.

14089 * doc/autoconf.texi (One Macro Call): Fix an incorrect
14090 example, and add more examples. Reported by Eric Sunshine.

14112 * lib/autoconf/general.m4 (AC_ARG_PROGRAM):
14113 Use "rm -f" to remove conftest.sed, not plain "rm".
14114 Bug reported by David Relson in
14115 <http://mail.gnu.org/archive/html/autoconf/2004-01/msg00011.html>.
14117 * Makefile.am (autom4te-update):
14118 Replace "rm -rf" and "rm -fr" with "rm -f -r", as POSIX requires.

14134 * doc/autoconf.texi (Limitations of Usual Tools): Mention that cc
14135 -c -o might not work. From a suggestion by Kevin Ryde.
14136 (C Compiler, Generating Sources, Limitations
14137 of Usual Tools, Limitations of Make, Making testsuite Scripts):
14138 Don't put '-o' after non-options, as POSIX doesn't allow this.
14139 Mention that cc's name might be gcc or c89 or whatever.
14141 2004-01-04 Kevin Ryde <user42@zip.com.au>
14143 * doc/autoconf.texi: Add various further index entries.

14147 * bin/autoreconf.in (autoreconf_current_directory):
14148 Fix typo: mkdir without umask arg.
14150 2003-12-27 Alexandre Duret-Lutz <adl@gnu.org>
14152 * doc/autoconf.texi (Limitations of Make) <Automatic rule rewriting>:
14153 Documents OSF1/Tru64 make behavior. Replace `VPATH = ../src' by

14155 explanation clearer.

14166 * tests/atlocal.in: Store the result here.
14167 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Extracted from

14169 of explicitly testing.
14170 (AT_CHECK_PERL_SYNTAX): Moved from tools.at.
14171 (AT_CHECK_AUTOCONF): Test for the configure script syntax.
14172 * tests/tools.at (Syntax of the shell scripts): Simplify

14440 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Omit quoted

14466 cache variable instead of $G77 to decide whether to include -O2,

14477 arguments so that it can be used with syntax identical to

14479 remove/deprecate the DIALECT optional argument in the future if it
14480 proves troublesome.
14481 (AC_FC_FREEFORM): Exit 77 upon failure to fix test suite for

14553 * lib/autoconf/status.m4 (_AC_OUTPUT_COMMANDS): Make sure the
14554 directory for AC_CONFIG_COMMANDS' first argument exists.
14555 This makes valid the invocation of _AC_SRCPATH that follows.
14556 Reported by Eric Sunshine.

14580 The test suite are sometimes assigning timings incorrectly.
14581 Reported by Henk Krus.
14582 Diagnosed by Nicolas Joly.
14584 * lib/autotest/general.m4 (AT_CLEANUP): Rename AT_help as
14586 Instead of making AT_help a sequence of assignments to grow

14588 $at_help_all, and make a single assignment in...
14590 (at_times_skip): Flip the meaning and rename as...
14591 (at_times_p): this.

14604 executables, not bin/ executables! Otherwise all the magic needed
14605 to find non installed files is turned off. This caused a failure
14606 of test 40 and 41 that ran aclocal 1.8 which in turn ran autom4te
14607 as found in its environment (sent by tests/autoreconf): pointing
14608 to bin/autom4te that could not find its files.
14609 * tests/mktests.sh: Force the replacement of generated files, for
14610 the sake of "mv" program that are interactive when overwriting a

14701 2003-09-04 Akim Demaille <akim@epita.fr>
14703 * tests/mktests.sh (ac_exclude_list): Add AC_FC_FUNC.
14705 2003-09-02 Steven G. Johnson <stevenj@alum.mit.edu>
14707 Add support for newer Fortran dialects. The F77 interface is
14708 unchanged, and continues to support Fortran 77. New FC macros
14709 correspond to all the old F77 macros, with output variables FC,
14710 FCFLAGS, and FCLIBS. AC_PROG_FC defaults to picking the newest
14711 available dialect, but older dialects can be specified. There are
14712 new macros AC_FC_SRCEXT to set the source extension, and
14713 AC_FC_FREEFORM to accept free-form source files.
14715 * lib/autoconf/c.m4 (_AC_LANG_PREFIX(C), _AC_LANG_PREFIX(C++)):
14717 (AC_LANG_PROGRAM(C)): Invoke _AC_LANG_PROGRAM_C_FC_HOOKS if defined.

14833 * bin/autoheader.in (&parse_args): Use &parse_warnings and

14837 * lib/Autom4te/General.pm: Don't export error: you don't own it.
14839 2003-08-21 Akim Demaille <akim@epita.fr>
14841 First stab at preserving warnings between calls to autom4te,
14842 including when the cache is used.
14844 There are still several issues: (i) there are too many runs of m4
14845 (one for include, one for warnings, and some more), (ii) warnings
14846 spreading on several lines are not handled gracefully, (iii) the
14847 code meant to have the call stack display for errors does not work
14848 (its handling should move from m4 to autom4te).
14850 * bin/autom4te.in Autom4te::Channels, Autom4te::ChannelDefs):
14852 (@preselect): Add m4_warn.
14853 ($exit_status): Remove, use $exit_code.
14854 ($help): Use Autom4te::ChannelDefs::usage.
14855 (&handle_m4): No longer define the m4_warnings.
14856 At each run, extract and report the warnings.
14857 Always cache the result, including if the exit status is on
14858 failure, since if nothing changes, we should result in the same
14859 failure, hence we can use the cache.
14860 * lib/m4sugar/m4sugar.m4 (m4_warning_ifelse, _m4_warning_ifelse)
14861 (_m4_warning_error_ifelse, __m4_warning_error_ifelse, _m4_warn):
14863 (m4_warn): Redefine as a do-nothing: it is its invocation that
14864 matters, as warnings are now reported via traces.
14865 * lib/autoconf/general.m4 (AC_DIAGNOSE): Don't make it a copy of
14866 the contents of m4_warn: make it _call_ m4_warn, so that tracing
14867 the latter reveals calls to the former.
14871 * tests/m4sugar.at (m4@&t@_warn): Use existing warning categories.
14873 2003-08-21 Akim Demaille <akim@epita.fr>

14883 (&parse_warnings): Accept a list of warning requests.
14884 (&usage): Return a string, not a side effect.
14885 (cross): New warning category.

14889 * lib/Autom4te/Configure_ac.pm (&find_configure_ac)
14890 (&require_configure_ac): Accept an optional directory argument.
14891 ($configure_ac): Remove.
14892 * lib/Autom4te/General.pm (&find_configure_ac, &canonfile)
14893 (&catfile): Remove.
14894 * bin/autoheader.in, bin/autoreconf.in, bin/autoupdate.in,
14895 * bin/autoscan.in: Adjust.
14897 2003-08-20 Akim Demaille <akim@epita.fr>
14899 * bin/autoheader.in: Remove duplicate 'use Autom4te::FileUtils'.
14900 Reported by Alexandre Duret-Lutz.
14902 2003-08-20 Akim Demaille <akim@epita.fr>
14904 * bin/autoupdate.in, bin/autoheader.in, bin/autoreconf.in,
14905 * bin/autom4te: Adjust.
14906 In particular, be Autoconf tools are really silent when properly
14907 working, bind the verbosity of the 'note' channel to $verbose.
14908 * lib/Autom4te/General.pm (&find_file, &mtime, &update_file)
14909 (&xsystem, &contents): Remove, since they are exported by...
14910 * lib/Autom4te/FileUtils.pm: this.

14913 * lib/Autom4te/FileUtils.pm: here.

15032 * lib/autotest/general.m4 (AT_INIT): Report a single config.log,
15033 not all of them. This fixes 1. the fact that when testing
15034 Autoconf there are many many config.log, 2. the incorrect use of
15035 top_srcdir to find config.log.
15036 Don't mix the detailed output of failed test with the summary of
15037 failures. Rather, append detailed log afterwards.
15039 2003-06-23 Akim Demaille <akim@epita.fr>
15041 * tests/local.at (AT_CHECK_CONFIGURE): Adjust to the verbose being

15166 as that's closer to how it'll be used.
15168 2003-05-23 Akim Demaille <akim@epita.fr>
15170 * doc/autoconf.texi (Header Portability): ucred.h.
15173 2003-05-22 Paolo Bonzini <bonzini@gnu.org>
15175 Overhaul Autotest's logging: generate separate log files
15176 in testsuite.dir/NNN/testsuite.log, and append them to
15177 testsuite.log instead of re-running the test verbosely.
15179 * lib/autotest/general.m4 (AT_INIT): Use a single redirected
15180 file descriptor, write 0 to at_status_file instead of setting
15181 at_status=0, initialize some new variables (at_status_file,
15182 at_group_log, at_suite_log, at_tee_pipe). Remove the cruft
15183 to rerun the tests, instead append the at_group_log to the
15184 at_suite_log when a test fails.
15185 (AT_SETUP): pipe the test case's output into at_tee_pipe,
15186 with the AS_MESSAGE_LOG_FD redirected to stdout.
15187 (AT_CLEANUP): save the output status in $at_status_file
15188 and restore it, redirect the AS_MESSAGE_LOG_FD back to
15189 its original place.
15190 (AT_CHECK): since tests are run with a redirected stdout,
15191 and used to be re-run in verbose mode, turn some $at_verbose
15192 into echo, and don't redirect the output of testing stdout
15195 * lib/autotest/autoconf.texi (testsuite Scripts): Update

15316 2003-05-06 Akim Demaille <akim@epita.fr>
15318 Don't try to be smart with aclocal 1.8+ because (i) aclocal no
15319 longer updates aclocal.m4 if useless, (ii) if a file m4_included
15320 by aclocal.m4 is changed it might require the importing of another
15321 m4 extension file, i.e., aclocal must be run.
15323 * bin/autoreconf.in (&run_aclocal, $aclocal_supports_force): New.
15324 (&parse_args): Use --force with aclocal if required and supported.

15338 2003-04-29 Derek Price <derek@ximbiot.com>
15340 * lib/autotest/general.m4 (AT_KEYWORDS): Don't use a comma as the
15341 seperator with m4_append_uniq(). It doesn't work.
15342 (AT_CLEANUP): Add `;' to end of at_help_all.
15343 (AT_INIT): Allow --keywords to be specified more than once. When
15344 grepping $at_help_all for keywords, use the field and keyword

15350 * doc/autoconf.texi: Make the dir entries in the autoconf manual
15351 align better with others. I also made some of the individual
15352 entries on one line, for brevity and to make it easier for me to
15353 sort my dir-example file in the Texinfo distribution :).

15594 _AC_PROG_PREPROC_WORKS_IFELSE): Use <limits.h> if __STDC__ is
15595 defined, to support freestanding compilers. This should fix the
15596 bug reported by Momchil Velkov in

15599 * doc/autoconf.texi (Obsolete Macros): Fix typos (insert empty
15600 arg, AC_DEFINE -> AC_DEFINE_UNQUOTED) in documentation for

15635 * Makefile.maint: Sync with Bison, i.e.:
15636 (po-check): Scan .l and .y files instead of the
15637 .c and the .h files that they generate. This fixes the bug
15638 reported by Tim Van Holder in:

15656 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Initialize f=$1 rather
15657 than assigning in main, to avoid HP cc +O3 optimizing it away.
15659 2002-11-12 Peter Eisentraut <peter_e@gmx.net>
15661 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Add -q
15662 option. Process --recheck after parsing all options. Pass -q
15663 option to configure on --recheck.
15664 (AC_OUTPUT): Pass -q from configure to config.status.
15665 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Strip -q from
15666 arguments to record.
15667 * doc/autoconf.texi (config.status Invocation): Document
15668 config.status -q option.
15670 2002-11-07 Alexandre Duret-Lutz <adl@gnu.org>
15672 * bin/autoscan.in (scan_file): Scan Makefile.am too. Ignore
15673 Makefile.in if Makefile.am exists.
15674 (output): Strip `.am' from Makefiles. Don't
15675 output AC_CONFIG_FILES if no Makefiles were found.

15695 Reported by Ezra Peisach.
15697 2002-11-05 Akim Demaille <akim@epita.fr>
15699 * lib/autoconf/autoheader.m4 (_AH_TEMPLATE_OLD, _AH_VERBATIM_OLD):
15701 We _have_ to stop using the old compatibility scheme that tried to
15702 avoid useless backslashes because Libtool 1.4.3 contains a
15703 AC_DEFINE([error_t], [int],
15704 [Define to a type to use for \`error_t' if it is not
15705 otherwise available.])
15706 We _have_ to quote the single quote and backslashes with \. The
15707 old compatibility scheme saw that ` was backslashed, and therefore
15708 did not quote the single quote. Hence before this patch, Autoconf
15709 was not compatible with Libtool.

15733 * doc/autoconf.texi (autoreconf Invocation): Adjust.

15754 `$(MAKE)' instead of '${MAKE}' to emphasize that we refer to the
15755 Make variable, not a shell variable.
15756 Suggested by Bruno Haible.

15760 * bin/autom4te.in (load_configuration): Reject #args out of any

16152 * tests/torture.at (AC_ARG_VAR): Have configure report the value
16155 2002-10-11 Akim Demaille <akim@epita.fr>
16157 * lib/m4sugar/m4sh.m4 (_AS_PATH_SEPARATOR_PREPARE): Use $$ in the
16158 file name to enable parallel executions.
16159 From Sam Varshavchik.
16161 2002-10-08 Akim Demaille <akim@epita.fr>
16163 * bin/autoreconf.in (&autoreconf): Run autopoint before the first
16164 aclocal invocation, as Gettext macros might not be visible to
16166 Instead of blindly running autopoint, scan configure.ac (not the
16167 traces) for AM_GNU_GETTEXT_VERSION uses, as autopoint does.
16168 Reported by Paul D. Smith.
16170 2002-10-08 Paul Eggert <eggert@twinsun.com>
16172 Work around problems found when POSIXLY_CORRECT=1 is set.
16173 None of this seems to have anything to do with POSIX, really,
16174 but it's how Perl getopt works.
16175 * bin/autom4te.in (parse_args): Configure GetOpt with
16177 * doc/autoconf.texi (Invoking autom4te):
16178 --warning -> --warnings.
16179 * lib/autom4te.in: --warning -> --warnings.
16181 2002-09-28 Akim Demaille <akim@epita.fr>
16183 * doc/autoconf.texi (autom4te.cache): New section.
16185 2002-09-28 Akim Demaille <akim@epita.fr>
16187 * lib/autom4te.in (Autoscan-preselections, Autoreconf-preselections)
16188 (Automake-preselections): Update.
16189 * bin/autoreconf.in, bin/autoheader.in: Comment changes.
16191 2002-09-28 Akim Demaille <akim@epita.fr>
16193 * lib/autoscan/autoscan.pre: Move all the remaining rules to...
16194 * lib/autoconf/c.m4, lib/autoconf/functions.m4,
16195 * lib/autoconf/headers.m4, lib/autoconf/libs.m4,
16196 * lib/autoconf/specific.m4, lib/autoconf/types.m4: here.
16198 2002-09-28 Akim Demaille <akim@epita.fr>
16200 * tests/torture.at (Configuring subdirectories): Be robust to
16201 users who use config.site to require for a cache: in this case,
16202 the two last configure runs, using two different sets of
16203 arguments, trigger a legitimate error.
16205 2002-09-28 Akim Demaille <akim@epita.fr>
16207 * tests/m4sh.at (Functions Support, Functions and return Support):
16210 2002-09-28 Akim Demaille <akim@epita.fr>
16212 * bin/Makefile.am (ETAGS_SH, ETAGS_PERL): Update: ifnames and
16213 autoheader are Perl programs.
16214 (autoconf, autoheader, autoreconf, autoupdate, ifnames, autoscan)
16215 (autom4te): Specify that the sources are in the $srcdir.
16216 * doc/autoconf.texi (Installation Directory Variables): Adjust.
16218 2002-09-28 Akim Demaille <akim@epita.fr>

16221 (tm_zone): Move their rules to...
16222 * lib/autoconf/types.m4: here, using AN_ macros.
16223 * lib/autoscan/autoscan.pre (AWK, BISON, INSTALL, LEX, LN, MAKE)
16224 (RANLIB, YACC, awk, bison, byacc, flex, gawk, install, lex, ln)
16225 (make, mawk, nawk, ranlib, yacc): Similarly, move to...
16226 * lib/autoconf/programs.m4: here.

16228 (ETAGS_FOR_AUTOCONF): New.
16231 2002-09-28 Akim Demaille <akim@epita.fr>
16233 * lib/autoconf/autoscan.m4: New file.
16234 * lib/autoconf/autoconf.m4: Include it.
16235 * lib/autoconf/functions.m4: Use AN_FUNCTION for all the functions
16236 that were listed in the original autoscan.list.
16237 * lib/autoconf/headers.m4: Similarly with headers.
16238 * lib/freeze.mk (autoconf_m4f_dependencies): Add autoscan.m4.
16239 (.m4.m4f): Don't pass --prepend-include, since that's done by
16240 tests/autom4te itself.
16241 * lib/autoscan/Makefile.am: Include freeze.mk.
16242 (autoscan.list): New target --this file is no longer a source.
16243 (autoscan.pre): New file.
16245 2002-09-28 Akim Demaille <akim@epita.fr>
16247 * bin/autoscan.in (@kinds): Make them singular.
16249 (&init_tables): When --debug, report the list of rules to ease
16250 tracking changes in autoscan.list.
16251 * lib/autoscan/autoscan.list (function): Strip comments, sort.
16253 2002-09-28 Akim Demaille <akim@epita.fr>
16255 * lib/autoscan/functions, lib/autoscan/headers,
16256 * lib/autoscan/identifiers, lib/autoscan/makevars,
16257 * lib/autoscan/programs: Merge into...
16258 * lib/autoscan/autoscan.list: this.
16259 * bin/autoscan.in (&init_tables): Adjust.
16261 2002-09-28 Akim Demaille <akim@epita.fr>
16263 * lib/autoscan/functions, lib/autoscan/headers,
16264 * lib/autoscan/identifiers, lib/autoscan/makevars,
16265 * lib/autoscan/programs: Make the `kind' explicit, i.e., each
16266 `functions' line is now prefixed with `function:'.
16267 * bin/autoscan.in (&init_tables): Adjust.
16269 2002-09-28 Akim Demaille <akim@epita.fr>
16271 From now on, autoscan files must always map a macro name to a
16272 word: there is no `default' macro for autoscan.
16274 * bin/autoscan.in (&init_tables): Reject entries with no macro at
16276 * lib/autoscan/functions, lib/autoscan/headers: Make the macro
16279 2002-09-28 Akim Demaille <akim@epita.fr>
16281 * bin/autoscan.in (%c_keywords): Remove.
16282 (&used): Keep only track of the words we might be interested in.
16283 (&output_kind): It is no longer needed to look for non active
16286 2002-09-27 Akim Demaille <akim@epita.fr>
16288 * lib/autoconf/functions.m4 (AC_FUNC_MBRTOWC): New, stolen from
16289 jm_FUNC_MBRTOWC, by Paul Eggert, from the Coreutils 4.5.1.
16290 * lib/autoscan/functions: Adjust.
16291 * doc/autoconf.texi (Particular Functions): Adjust.
16293 2002-09-27 Akim Demaille <akim@epita.fr>
16295 * doc/autoconf.texi (Limitations of Usual Tools): Some about mv
16297 Thanks to Bill Moseley and Paul Eggert.
16298 * lib/m4sugar/m4sh.m4 (AS_TMPDIR): $2 is the directory into which
16299 the tmpdir must be created.
16300 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Have the tmp
16301 dir be in the build tree, instead of $TMPDIR.
16303 2002-09-27 Akim Demaille <akim@epita.fr>
16305 * bin/autoscan.in: Improve the comments.
16306 (&parse_args): Drop obsolete undocumented options.
16307 (&output_kind): Output warnings.
16308 * lib/autoscan/functions: (dcgettext): Now trigger AM_GNU_GETTEXT.
16309 (getwd): Trigger a warning.
16311 2002-09-26 Akim Demaille <akim@epita.fr>
16313 * bin/autoreconf.in: Clarify that -s is meaningless without -i.
16314 Reported by Ralf Corsepius.
16315 * doc/autoconf.texi (autoreconf Invocation): Likewise.
16317 2002-09-26 Akim Demaille <akim@epita.fr>
16319 Single suffix rules and seperated dependencies are not portable.
16321 * doc/autoconf.texi (Installation Directory Variables): Update.
16322 (Limitations of Make): Some about `Single Suffix Rules and
16323 Separated Dependencies'.
16324 * bin/Makefile.am (autoconf, autoheader, autoreconf, autoupdate)
16325 (ifnames, autoscan, autom4te): Un-factor into several rules.
16327 2002-09-25 Paul Eggert <eggert@twinsun.com>
16329 * BUGS (Interoperability bugs): New section. Mention libtool
16330 1.4.2, configure.ac, and AC_CONFIG_AUX_DIR interoperability bug.
16332 2002-09-24 Paul Eggert <eggert@twinsun.com>
16334 Fix a portability bug reported by Alexandre Duret-Lutz: Solaris 8
16335 make handles suffix-rules differently from GNU make.
16337 * bin/Makefile.am (SUFFIXES, .in): Remove.
16338 (autoconf autoheader autoreconf autoupdate ifnames autoscan autom4te):
16339 Move the body of the old .in rule here.
16341 2002-09-16 Akim Demaille <akim@epita.fr>
16343 i960 compilers create `b.out' files by default.
16344 Reported by Ralf Corsepius.
16346 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT): Remove b.out files.
16347 (_AC_COMPILER_EXEEXT_DEFAULT): Adjust to b.out.
16349 2002-09-13 Paul Eggert <eggert@twinsun.com>
16351 * doc/autoconf.texi (Particular Headers): Remove obsolete
16352 reference to `struct timezone' in the description of
16355 2002-09-13 Akim Demaille <akim@epita.fr>
16359 * config/config.sub, config/config.guess: Update.
16360 * Makefile.maint: Update from bits of the Coreutils 4.5.1.
16361 * Makefile.am: Adjust.
16363 2002-09-13 Akim Demaille <akim@epita.fr>
16365 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Suggest
16366 reading config.log when the compiler is rejected.
16367 Suggested by Guido Draheim.
16369 2002-09-13 Akim Demaille <akim@epita.fr>
16371 * bin/autoreconf.in: Don't use Cwd::chdir, since in its internals
16372 (chdir_init) might hang when stat'ing mounted directories.
16373 Reported by Vance Shipley.
16375 2002-09-12 Akim Demaille <akim@epita.fr>
16377 * bin/autoscan.in (&parse_args): Pass a reference to the lists, not
16380 2002-09-12 Akim Demaille <akim@epita.fr>
16382 * doc/autoconf.texi (Defining Symbols): Present two different
16383 prototypes for AC_DEFINE and AC_DEFINE_UNQUOTED to emphasize the
16384 difference between 1 argument calls, and 2-3 argument calls.
16386 2002-09-12 Peter Eisentraut <peter_e@gmx.net>
16388 * doc/autoconf.texi: Review grammar and punctuation.
16390 2002-09-11 Paul Eggert <eggert@twinsun.com>
16392 * doc/autoconf.texi: Fix minor formatting, spelling, and
16394 (Defining Symbols): Explain that AC_DEFINE(var) defaults to 1, but
16395 AC_DEFINE(var,,description) does not; and the AC_DEFINE(var) case
16398 2002-09-11 Akim Demaille <akim@epita.fr>
16400 * doc/autoconf.texi (Questions): Rename as...
16402 (Defining Directories): New.
16404 2002-09-09 Akim Demaille <akim@epita.fr>
16406 * doc/autoconf.texi (Making testsuite Scripts): Update.
16407 Suggested by Nishio Futoshi.
16409 2002-09-09 Koji Arai <JCA02266@nifty.ne.jp>
16411 * doc/autoconf.texi (Making testsuite Scripts): Use `@@' where a
16412 plain `@' is wanted.
16414 2002-09-09 Akim Demaille <akim@epita.fr>
16416 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Keep the
16417 `duplicates', since the algorithm was too naive and could keep
16418 `--prefix=1 --prefix=2 --prefix=1' as `--prefix=1 --prefix=2', and
16419 keep `--prefix foo --prefix bar' as `--prefix foo bar'.
16420 Reported by Ralf Corsepius.
16421 * tests/torture.at (Configuring subdirectories): Exercise these
16424 2002-09-09 Akim Demaille <akim@epita.fr>
16426 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Use $srcdir when
16427 looking for a replacement file.
16428 * lib/autoconf/general.m4 (AC_CHECK_DECLS): Check that the
16429 directory is relative.
16430 * doc/autoconf.texi (Generic Functions): Clarify the replacement
16431 directory definition.
16432 Reported by Andreas Schwab and Jim Meyering.
16434 2002-09-06 Akim Demaille <akim@epita.fr>
16436 * doc/autoconf.texi (Setting Output Variables): Clarify what
16437 precious variables are.
16438 Suggested by Pontus Skoeld.
16440 2002-09-05 Akim Demaille <akim@epita.fr>
16442 * bin/Makefile.am (autoconf, autoheader, autoreconf, autoupdate)
16443 (ifnames, autoscan, autom4te): Since we don't only depend on
16444 configure.ac variables (such as VERSION etc.), but also on prefix
16445 and so forth, depend on Makefile, not configure.ac.
16446 Reported by Alexandre Duret-Lutz.
16447 * doc/autoconf.texi (Installation Directory Variables): Adjust.
16449 2002-09-05 Kevin Ryde <user42@zip.com.au>
16451 * doc/autoconf.texi (Limitations of Make): HP-UX trailing backslashes
16452 doesn't seem to be confined to ia64, just say "some versions".
16454 2002-09-04 Akim Demaille <akim@epita.fr>
16456 * Makefile.am, doc/Makefile.am: Remove pdf targets, handled by
16458 * Makefile.am (maintainer-clean-local): Remove.
16459 (MAINTAINERCLEANFILES): Remove COPYING.
16461 2002-09-03 Paul Eggert <eggert@twinsun.com>
16463 * doc/autoconf.texi (Configuration Commands): Remove obsolete
16464 example for AC_CONFIG_COMMANDS_PRE. Problem reported by Marcus
16467 2002-09-03 Akim Demaille <akim@epita.fr>
16469 * configure.ac: Bump to 2.53d.
16470 * Makefile.am (AUTOMAKE_OPTIONS): Require 1.6c, i.e., CVS Automake
16471 as of today, on Automake's team suggestion.
16473 2002-09-03 Akim Demaille <akim@epita.fr>
16477 2002-09-02 Akim Demaille <akim@epita.fr>
16479 * bin/autom4te.in (parse_args): Don't honor AUTOM4TE_PATH and
16481 * configure.ac: Disable SITE_MACRO_DIR.
16483 2002-09-02 Jim Meyering <meyering@lucent.com>
16485 * doc/autoconf.texi (AC_SYS_POSIX_TERMIOS): Reflect renaming: s/am/ac/,
16486 i.e., change am_cv_sys_posix_termios to ac_cv_sys_posix_termios.
16487 Also, tweak grammar: s/make sure to/be sure to/.
16489 2002-09-02 Paul Eggert <eggert@twinsun.com>
16491 * doc/autoconf.texi (Limitations of Builtins): Explain why logical
16492 directory names are generally preferable to physical names.
16494 2002-09-02 Akim Demaille <akim@epita.fr>
16496 * lib/Autom4te/General.pm (&update_file): s/die/error/.
16497 Reported by Raja R. Harinath.
16498 * bin/autoheader.in, bin/autoreconf.in, bin/autoscan.in,
16499 * bin/autoupdate.in: Use error instead of die.
16501 2002-09-01 Paul Eggert <eggert@twinsun.com>
16503 * tests/mktests.sh (ac_exclude_egrep, au_exclude_egrep): Use
16504 ordinary shell concatenation rather than echo+tr+sed command that
16505 runs afoul of a long-line-related sed bug in Solaris 8.
16507 * bin/autoheader.in (parse_args): --warning -> --warnings.
16509 * bin/autoconf.as: Work even if "ls" outputs "FOO not found" to
16510 stdout, as traditional "ls" does.
16511 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT,
16512 _AC_COMPILER_EXEEXT_O): Likewise.
16513 * doc/autoconf.texi (Limitations of Usual Tools): Add "ls".
16515 * bin/autoconf.as: Add --prepend-include option. This patch was
16516 applied to bin/autoconf.in in the 2002-07-17 patch by Mark D. Roth,
16517 but bin/autoconf.in is generated automatically from bin/autoconf.as.
16519 * bin/autoconf.in, configure: Regenerate.
16521 * doc/autoconf.texi (Special Shell Variables): Mention
16522 ENV, MAIL, MAILPATH, PS1, PS2, PS4. Index PWD.
16524 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Unset ENV, MAIL,
16525 MAILPATH and set PS1, PS2, PS4 to default values, to work
16526 around bug in pre-3.0 UWIN ksh reported by Bruce Lilly.
16527 For LC_ALL etc, first try to set to "C" as POSIX requires and as
16528 the Autoconf documentation specifies; fall back to "unset" only if
16529 this fails. Use a shell for-loop for this rather than an m4 loop,
16530 to shorten the output script.
16532 2002-08-30 Paul Eggert <eggert@twinsun.com>
16534 * doc/autoconf.texi (Special Shell Variables): Mention POSIX
16535 1003.1-2001's requirements for CDPATH. Give a simpler workaround
16536 for the CDPATH problem. Document PWD.
16537 (Limitations of Builtins): Document the problem that "cd $foo" and
16538 "ls $foo" may refer to different directories in shells conforming
16539 to POSIX 1003.1-2001. Use PS1 rather than CDPATH for "unset"
16540 example, since the old example is now out of date.
16542 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Reject FOO if "cd
16543 FOO" and "ls FOO" talk about different directories; this catches
16544 problems when POSIX 1003.1-2001 "cd" fails due to symlink
16547 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Use AS_UNSET instead
16548 of rolling our own unset.
16549 (_AS_PREPARE): $as_unset CDPATH instead of AS_UNSETting it, since
16550 in practice we needn't worry about CDPATH if unset doesn't work.
16552 * Makefile.in, aclocal.m4, bin/Makefile.in,
16553 config/Makefile.in, doc/Makefile.in, lib/Makefile.in,
16554 lib/Autom4te/Makefile.in, lib/autoconf/Makefile.in,
16555 lib/autoscan/Makefile.in, lib/autotest/Makefile.in,
16556 lib/emacs/Makefile.in, lib/m4sugar/Makefile.in, man/Makefile.in,
16557 tests/Makefile.in: Regenerate with Automake 1.6.3.
16559 * config/config.guess, config/config.sub, config/mkinstalldirs:
16562 * configure: Regenerate with self.
16564 2002-08-30 Kevin Ryde <user42@zip.com.au>
16566 * doc/autoconf.texi (Limitations of Usual Tools): Notes on "cc"
16569 2002-08-29 Rainer Orth <ro@TechFak.Uni-Bielefeld.DE>
16571 * bin/autom4te.in (Request::load): Correctly test for "do" read
16574 2002-08-29 Akim Demaille <akim@epita.fr>
16576 * lib/Autom4te/General.pm (&xqx): New.
16577 (&xsystem): Use WIFEXITED and WEXITSTATUS instead of decoding $? by
16578 hand, which is not portable.
16580 * bin/autom4te.in: Use them.
16581 Use &error instead of die.
16582 * tests/m4sugar.at (m4_warn, m4_require: circular dependencies):
16585 2002-08-17 Paul Eggert <eggert@twinsun.com>
16587 * lib/autoconf/fortran.m4 (AC_PROG_F77): Remove fc from the
16588 default list of compilers to try, since it was long ago superseded
16589 by the ksh fc builtin. Suggested by Steven G. Johnson.
16591 2002-07-31 Alexandre Duret-Lutz <duret_g@epita.fr>
16593 * doc/autoconf.texi (Invoking autom4te): End the option table,
16594 fixing a bug introduced by the previous patch.
16595 (Limitations of Make): Add a 'target lookup' subentry in the
16596 'VPATH' entry. Rewrite all `make' occurences as `@command{make}'.
16598 2002-07-29 Mark D. Roth <roth@feep.net>
16600 * bin/autom4te.in: Remove --include-envvar and --site-macro-subdir
16601 options and use $AUTOM4TE_PATH.
16602 * doc/autoconf.texi: Remove documentation of autom4te
16603 --include-envvar and --site-macro-subdir options and document
16604 use of $AUTOM4TE_PATH.
16605 * lib/autom4te.in: Remove --include-envvar and --site-macro-subdir
16606 arguments from each language section.
16608 2002-07-29 Paul Eggert <eggert@twinsun.com>
16610 * doc/install.texi: Include copyright symbol in copyright notice.
16612 * Makefile.am (MAKEINFO): Remove; it's a user-specified macro.
16614 (AM_MAKEINFOFLAGS): New macro.
16615 * doc/Makefile.am (MAKEINFO, AM_MAKEINFOFLAGS): Likewise.
16616 * Makefile.am (INSTALL): Use the new macros.
16617 Use -o rather than --output, since "missing" does not grok --output.
16619 2002-07-25 Alexandre Duret-Lutz <duret_g@epita.fr>
16621 * doc/autoconf.texi (Limitations of Make): Escaped newlines in
16622 comments do not always work. Never trust the exit status of
16625 2002-07-24 Kevin Ryde <user42@zip.com.au>
16627 * doc/autoconf.texi (Limitations of Make, Making testsuite Scripts):
16628 Untabify, since tabs are not enjoyed by texi2dvi and makeinfo.
16630 2002-07-23 Paul Eggert <eggert@twinsun.com>
16632 * lib/m4sugar/m4sh.m4 (_AS_PATH_SEPARATOR_PREPARE):
16633 Use PATH="/nonexistent;.", not PATH=".;.", as FreeBSD ksh2002
16634 apparently treats PATH="nonexistent" as if it contained ".".
16635 Bug reported by Stefan `Sec' Zehl.
16637 2002-07-22 Alexandre Duret-Lutz <duret_g@epita.fr>

16905 This improves on an earlier suggestion by H. Peter Anvin.
16907 2002-05-16 Paul Eggert <eggert@twinsun.com>
16909 AC_FUNC_FNMATCH now tests only for POSIX compatibility.
16910 AC_FUNC_FNMATCH_GNU also tests for GNU extensions.
16911 Both macros now accept an optional source-dir arg.
16912 New macro AC_GNU_SOURCE to define _GNU_SOURCE.
16914 * NEWS: Document this.
16915 * doc/autoconf.texi (Particular Functions, UNIX Variants): Likewise.
16917 * lib/autoconf/functions.m4 (_AC_FUNC_FNMATCH): New macro.
16918 (AC_FUNC_FNMATCH): Use it. Test only for POSIX conformance,
16919 not for GNU extensions; this undoes part of the 2000-11-03 change,
16920 reverting to 2.13-compatible behavior.

16922 (AC_FUNC_FNMATCH_GNU): New macro.

16928 * lib/autoconf/headers.m4 (AC_HEADER_TIOCGWINSZ):
16929 Don't require AC_SYS_POSIX_TERMIOS. The test is unnecessary,
16930 and it causes a 'test' syntax error if it fails.
16931 Bug reported by Stephen Gildea.
16933 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
16934 If prototypes are supported, use them to check this at compile-time,
16935 instead of trying to check it at run-time. If we must do a run-time
16936 check, assume that setvbuf is standard when cross-compiling, as
16937 nonstandard setvbuf occurs only on ancient and unlikely hosts.
16938 Bug reported by Paul D. Smith.
16940 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Add optional
16941 argument specifying location of getloadavg.c. This removes a
16942 FIXME. This idea was taken from Jim Meyering's implementation in
16944 * doc/autoconf.texi (Particular Functions): Document this.
16945 Also, mention HAVE_NLIST_H rather than NLIST_STRUCT, since
16946 that's what the code does; this fixes a bug reported by

16951 * bin/autoreconf.in (autoreconf): Rewrite to use Gettext's
16952 autopoint instead of gettextize.
16953 ($uses_alocal): Rename as...
16954 ($uses_aclocal): this.
16955 * doc/autoconf.texi (autoreconf Invocation): Adjust.
16956 Suggested by Bruno Haible.
16958 2002-05-03 Akim Demaille <akim@epita.fr>
16960 * lib/m4sugar/m4sugar.m4 (m4_map_sep): New.
16962 2002-04-29 Paul Eggert <eggert@twinsun.com>
16964 * bin/autoreconf.in (autoreconf): Don't age aclocal.m4's input
16965 files to be 1 second older; just set them to be the same time.
16966 Also, sleep 1 second after the first aclocal, to work around
16967 problems with sub-second time stamps on the input files.
16969 2002-04-29 Thien-Thi Nguyen <ttn@gnu.org>
16971 * doc/autoconf.texi: Mention "set -e -x" lossage
16972 under node "Limitations of Builtins".

16978 From Christian Cornelssen.
16980 2002-04-29 Akim Demaille <akim@epita.fr>
16982 * tests/m4sh.at (LINENO): If testsuite itself is rewritten because
16983 of lack of $LINENO support, then the test will compare the $LINENO
16984 in testsuite vs. the lineno in the test file. This is wrong, of
16986 Be sure to protect it.
16987 Reported by Patrick Welche.
16989 2002-04-25 Akim Demaille <akim@epita.fr>
16991 * doc/autoconf.texi (Obsolete Macros): Typo.
16992 Reported by Vladimir Volovich.
16994 2002-04-25 Akim Demaille <akim@epita.fr>
16996 * bin/autoreconf.in (autoreconf): Don't let aclocal.m4 be older
16997 than some of the input files, hence, on the second run of aclocal,
16998 if some of its input are younger, make them older.
16999 Suggested by Paul Eggert.
17001 2002-04-25 Akim Demaille <akim@epita.fr>
17003 * doc/autoconf.texi (Limitations of Usual Tools): sed and `!'.

17009 and ac_subst_vars be sh variables containing the list of
17010 AC_SUBST_FILES'ed and AC_SUBST'ed identifiers. Output them in the
17012 (_AC_INIT_PREPARE): Use them to log them.
17013 (_AC_SUBST, _AC_SUBST_SED_PROGRAM): Remove.
17014 (AC_SUBST, AC_SUBST_FILE): Instead of buliding the
17015 _AC_SUBST_SED_PROGRAM, store the list of output files/variables in
17016 _AC_SUBST_FILES and _AC_SUBST_VARS.
17017 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Adjust.
17019 2002-04-24 Akim Demaille <akim@epita.fr>
17021 * bin/autoreconf.in (autoreconf): Run automake after autoconf and
17022 autoheader, so that automake does not complain about a missing
17023 config.h.in that was to be created.
17025 2002-04-23 Akim Demaille <akim@epita.fr>

17120 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Install the Zsh
17121 workaround for ${1+"$@"}.
17122 * doc/autoconf.texi (Shell Substitutions): Explain it.
17123 From Oliver Kiddle and Peter Stephenson.
17125 Have M4sh perform minimal shell sanitizing.
17127 * lib/m4sugar/m4sh.at (AS_SHELL_SANITIZE): Split the `_AS_PREPARE_*'
17129 (_AS_PREPARE): this new macro.
17131 (AS_INIT): Invoke AS_SHELL_SANITIZE.
17132 * tests/m4sh.at (AT_DATA_LINENO): Use _AS_PREPARE.
17134 Adjust Autoconf and Autotest.
17136 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Don't invoke
17137 AS_SHELL_SANITIZE, AS_INIT did it, but invoke AS_PREPARE.
17138 * lib/autotest/general.m4 (AT_INIT): Likewise.
17139 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
17140 Invoke _AS_PREPARE (not AS_PREPARE) in addition to
17143 Use this M4sh to generate Autoconf's shell scripts.
17145 * tests/wrapsh.as: New, precursor of wrapsh.in.
17146 * tests/Makefile.am: Include lib/freeze.mk to get the dependencies
17147 on Autotest and M4sh.
17148 ($(TESTSUITE)): Use $(autotest_m4f_dependencies).
17149 (wrapsh.in): New target.
17150 * bin/autoconf.as: New, precursor of autoconf.in.
17151 (autoconf.in): New target.
17153 2002-04-09 Alexandre Duret-Lutz <duret_g@epita.fr>
17155 * doc/autoconf.texi (Limitations of Make): Mention the issue
17156 with indented comments in rules.

17171 directories when descending in a SUBDIRS.
17172 Reported by Ezra Peisach.
17174 2002-04-04 Andreas Schwab <schwab@suse.de>
17176 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Only simplify if path
17177 contains no literal separators.
17179 2002-04-03 Akim Demaille <akim@epita.fr>
17181 * lib/autoconf/status.m4 (_AC_CONFIG_FILE, _AC_CONFIG_HEADER)
17182 (_AC_CONFIG_COMMAND, _AC_CONFIG_LINK): New.
17183 Use dnl, not the KILL diversion.
17185 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_COMMANDS)
17186 (AC_CONFIG_LINKS): here.
17188 Don't use the KILL diversion, as it kills spurious output, which
17189 results in failures being hidden.
17190 Use m4_defn where appropriate.
17191 (AC_CONFIG_IF_MEMBER): Kill the real bug: a spurious parenthesis
17192 after the second argument.
17194 * lib/autom4te.in (Autoconf, Autotest, M4sh): Don't pass --warning
17195 syntax, as it is provided by M4sugar.
17196 * tests/torture.at (Multiple AC_CONFIG_FILES): New.
17198 2002-04-03 Andreas Schwab <schwab@suse.de>
17200 * lib/m4sugar/m4sugar.m4 (m4_bmatch): Make sure m4_bregexp is not
17201 expanded if $# <= 2.
17203 * bin/autoreconf.in (autoreconf): Run automake after rerunning
17206 2002-04-03 Akim Demaille <akim@epita.fr>

17212 (_AC_COMPILER_OBJEXT): Use them.
17213 Fixes Debian #138666.
17215 2002-04-02 Peter Eisentraut <peter_e@gmx.net>
17217 Integrate AC_PROG_CC_STDC into AC_PROG_CC.
17219 * lib/autoconf/c.m4 (AC_PROG_CC_STDC): Rename to _AC_PROG_CC_STDC.
17220 AU_DEFUN old name. Use _AC_COMPILE_IFELSE.
17221 (AC_PROG_CC): Call _AC_PROG_CC_STDC.
17222 (AC_C_INLINE): Do not require AC_PROG_CC_STDC.
17223 (AC_C_CONST): Same.
17224 (AC_C_INLINE): Same.
17225 (AC_C_PROTOTYPES): Same. Require AC_PROG_CC instead.
17226 * doc/autoconf.texi, NEWS: Document.

17233 _AS_MKDIR_P_PREPARE.
17235 2002-03-28 Kevin Ryde <user42@zip.com.au>
17237 * lib/autoconf/c.m4 (AC_C_INLINE): Test with a typedef return value,
17238 to avoid versions of HP C which don't allow that.
17240 2002-03-27 Paul Eggert <eggert@twinsun.com>
17242 * lib/m4sugar/m4sh.m4 (_AS_BASENAME_PREPARE): New macro.
17243 (AS_SHELL_SANITIZE): Invoke it.
17244 (AS_BASENAME): AS_REQUIRE it, and use $as_basename.

17248 * doc/autoconf.texi (Portable Shell): Add pointers to FAQs.
17250 2002-03-26 Akim Demaille <akim@epita.fr>
17252 * doc/autoconf.texi (Introduction): The GNATS base moved.
17254 2002-03-25 Paul Eggert <eggert@twinsun.com>
17256 * tests/m4sh.at: Don't rely on "PATH=test:$PATH test-1" working
17257 as POSIX requires, as it doesn't work with Zsh.
17258 * doc/autoconf.texi (Assignments): Document the problem.
17260 2002-03-25 Alexandre Duret-Lutz <duret_g@epita.fr>
17262 * doc/autoconf.texi (Limitations of Make): Mention more issue
17263 about VPATH, overriding of macros in sub-makes, and handling of
17266 2002-03-21 Paul Eggert <eggert@twinsun.com>
17268 * doc/autoconf.texi (Here-Documents): Mention Solaris 8 dtksh
17269 problem with here-document buffer boundaries.
17271 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Unset ENV and BASH_ENV
17272 when reinvoking the shell, to work around problems with installers
17273 who put strange things like "cd" commands in their environments.
17275 2002-03-19 Akim Demaille <akim@epita.fr>
17277 * tests/semantics.at (AC_C_BIGENDIAN): s/unknow/unknown/.
17280 2002-03-19 Akim Demaille <akim@epita.fr>
17282 * bin/autoscan.in (scan_file): Specify the location in `&used'
17286 2002-03-19 Akim Demaille <akim@epita.fr>
17288 * doc/autoconf.texi: Adjust @code/@command, @xref/@ref usage.
17289 From Nishio Futoshi.
17291 2002-03-19 Akim Demaille <akim@epita.fr>
17293 * lib/m4sugar/m4sugar.m4 (m4_define_default, m4_fst, m4_map): New.

17297 * doc/autoconf.texi (Programming in M4sh): Add AS_MKDIR_P.
17298 (Limitations of Usual Tools): Add mkdir section.
17300 * lib/m4sugar/m4sh.m4 (_AS_MKDIR_P_PREPARE): New macro.
17301 (AS_MKDIR_P): Require it. Use mkdir -p if available, falling
17302 back on AS_DIRNAME to compute prefixes otherwise; this is
17303 roughly what mkinstalldirs does. That way, we need not have
17304 our own filename disassembler. The old disassembler did not
17305 work with Solaris 8 dtksh, which is ksh Version M-12/28/93d.
17307 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP):
17308 Create at_test_all by a series of assignments,
17309 not by a single assignment of a long string. The latter causes ksh
17310 version 11/16/88g to silently misbehave on OpenServer 5.0.6a,
17311 presumably because of a buffer overrun.
17313 2002-03-14 Paul Eggert <eggert@twinsun.com>
17315 * lib/autotest/general.m4 (at_times_skip):
17316 Renamed from at_times. Now a boolean.
17317 ksh93 Version M-12/28/93d doesn't like 'x=times; $x'; it
17318 says 'times: not found'.
17320 2002-03-14 Akim Demaille <akim@epita.fr>
17322 * bin/autoreconf.in (&study_gettextize): New.
17323 (&autoreconf): Handle newest gettextize.
17324 Rerun aclocal if needed.
17325 Suggested by Andreas Schwab.
17327 2002-03-13 Akim Demaille <akim@epita.fr>

17334 Add information about stdint.h and inttypes.h from Paul Eggert.
17336 2002-03-13 Akim Demaille <akim@epita.fr>

17342 2002-03-12 Akim Demaille <akim@epita.fr>
17344 * lib/m4sugar/m4sh.m4 (AS_BASENAME_EXPR): AS_REQUIRE, not
17347 2002-03-11 Andreas Schwab <schwab@suse.de>
17349 * configure.ac: Explicitly check for EMACS since AM_PATH_LISPDIR
17350 does not do it if --with-lispdir is given.
17352 2002-03-08 Akim Demaille <akim@epita.fr>
17356 2002-03-08 Akim Demaille <akim@epita.fr>

17359 subdirectory should exist.
17361 2002-03-08 Akim Demaille <akim@epita.fr>
17363 * Makefile.am (AUTOMAKE_OPTIONS): 1.6.
17365 2002-03-08 Akim Demaille <akim@epita.fr>
17367 * bin/autom4te.in (&handle_m4): Do not foreach with `$_' as it
17368 aliases the actual variables, and modifications of the former
17371 2002-03-08 Akim Demaille <akim@epita.fr>
17373 * bin/autom4te.in (&handle_m4): Protect us from corrupted file
17374 because of C-c: have m4 output in tmp files, then mv them.
17376 2002-03-08 Akim Demaille <akim@epita.fr>
17378 * bin/autoconf.in, bin/autoheader.in, bin/autom4te.in,

17395 2002-03-04 Akim Demaille <akim@epita.fr>
17397 * doc/autoconf.texi (AC_LIBOBJ vs. LIBOBJS): New.
17398 * lib/autoconf/general.m4 (AC_INIT): More informative error
17399 message for LIBOBJ.
17401 2002-03-04 Akim Demaille <akim@epita.fr>
17403 * lib/freeze.mk ($(build_libdir)/m4sugar/version.m4): New, for
17406 2002-03-04 Akim Demaille <akim@epita.fr>
17408 * doc/autoconf.texi (Transforming Names): Equality between target
17409 and host is irrelevant.
17410 (Specifying Names, Canonicalizing): Remove all references to the
17411 backward compatibility hooks. Rather, collect them all into...
17412 (Hosts and Cross-Compilation): this new section.
17413 * doc/install.texi (System Type): Ditto.
17414 * lib/autoconf/general.m4 (AC_CANONICAL_HOST): Explicitly state
17415 that `--host' implies cross-compilation.
17417 2002-03-04 Akim Demaille <akim@epita.fr>
17419 * doc/autoconf.texi (Evaluation Macros): New.
17420 * lib/m4sugar/m4sugar.m4 (m4_lquote): Remove, it is totally
17422 (_m4_foreach): Define the variant with immediate evaluation so
17423 that it contains exactly the items, not an expression which
17424 evaluation is the current item.
17425 (m4_re_string, m4_re_word): Don't over quote them.
17427 2002-03-04 Akim Demaille <akim@epita.fr>
17429 Instead of having stacking `shift's evaluated at the end, let
17430 `foreach' loops immediately evaluate them.
17432 * lib/m4sugar/m4sugar.m4 (m4_quote, m4_dquote): Use $@ rather than
17433 $*. This is the n-th time I change my mind, but hopefully this is
17436 (m4_text_wrap): Use m4_foreach, which is finally correct _and_
17438 (m4_foreach_quoted, m4_car_quoted, _m4_foreach_quoted): Remove, as
17439 it was only a hack for m4_text_wrap.
17440 (m4_car2): Remove, replaced by...
17442 (_m4_foreach): Adjust.
17443 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Adjust, and use
17444 m4_bpatsubst for clarification.
17446 2002-03-04 Akim Demaille <akim@epita.fr>

17474 * lib/autoconf/functions.m4 (AC_FUNC_SETPGRP): Fix the test.
17475 From Akinori Musha.

17493 2002-02-07 Akim Demaille <akim@epita.fr>
17495 Fix Autoconf PR/207:
17496 AC_PREFIX_PROGRAM fails with dashed program names
17498 * lib/autoconf/general.m4 (AC_PREFIX_PROGRAM): Just use a fresh
17499 variable when looking for the prefix program.
17500 Now it also works for shell variables.
17502 2002-02-07 Akim Demaille <akim@epita.fr>
17504 * doc/autoconf.texi (Limitations of Builtins): More about
17507 2002-02-06 Akim Demaille <akim@epita.fr>

17510 case/esac, some shells don't support it.
17511 Reported by Zack Weinberg.
17512 * tests/torture.at (AC_CONFIG_COMMANDS with empty commands): New.
17514 2002-02-06 Akim Demaille <akim@epita.fr>
17516 * lib/autotest/general.m4 (AT_INIT): When handling --keywords, be
17517 sure not to introduce newlines in at_groups.

17531 * tests/semantics.at (AC_CHECK_SIZEOF): Check non-GCC
17532 cross-compilers, too. This undoes some of the most recent change
17535 2002-02-05 Akim Demaille <akim@epita.fr>
17537 * tests/Makefile.am (check_SCRIPTS): Use it, instead of WRAPPERS,
17538 to make sure they are up to date when `check' is run.

17554 * lib/autoconf/autoconf.m4, lib/autotest/general.m4,
17555 * lib/m4sugar/m4sh.m4: Don't include files given by autom4te.
17557 2002-02-05 Akim Demaille <akim@epita.fr>
17559 * bin/autom4te.in (&parse_args): Implement `frozen files are
17560 optional are the sum of the previous files on the command line'.
17561 Also, pass `--reload-state=' on them, so...
17562 (handle_m4): don't.
17563 * lib/autom4te.in (Autotest, Autoconf): Rely on M4sh.
17564 (M4sh): Rely on M4sugar.
17565 (Autotest, M4sh, M4sugar): Use frozen files.
17567 2002-01-31 Akim Demaille <akim@epita.fr>
17569 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Accept $4.
17570 * doc/autoconf.texi (Initializing configure): Adjust.
17572 2002-01-30 Akim Demaille <akim@epita.fr>
17574 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Map non
17575 alphanumeric to `-' instead of `_'.
17577 2002-01-30 Akim Demaille <akim@epita.fr>
17579 * tests/semantics.at (AC_CHECK_SIZEOF): Split into two tests: one
17580 for plain code, the other for cross-compilation code. The latter
17581 is now run with GCC only.
17582 * doc/autoconf.texi (Compilers and Preprocessors): New.

17586 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Support pre-defined
17588 * doc/autoconf.texi (Initializing configure): Explain how to
17589 change AC_INIT default values.
17591 2002-01-29 Akim Demaille <akim@epita.fr>
17593 * tests/torture.at (Configuring subdirectories): Use configure.in,
17594 so that aclocal 1.4 works.
17595 Reported by Alexandre Duret-Lutz and Larry Schmitt.
17597 2002-01-28 Akim Demaille <akim@epita.fr>
17599 * doc/autoconf.texi (Writing testsuite.at): AT_CLEANUP no longer
17602 2002-01-28 Akim Demaille <akim@epita.fr>
17604 * lib/autotest/general.m4 (AT_INIT): Don't be ridiculous: adjust
17605 AUTOTEST_PATH *after* it was set.
17606 Don't put `.' in the PATH: the user should be precise and `./' if
17607 needed. In addition, given that the test suite does some `cd', if
17608 `.' is in the path, the `tested programs' sections will report
17609 programs found in the test suite's directory, while during the
17610 tests (performed in their own directory), these programs are no
17611 longer visible. In other words, the results is confusing and
17613 * tests/m4sh.at: Adjust: don't rely on `.' being in the PATH.

17628 Bourne. Use /bin/sh.
17629 From Andreas Buening.

17657 * lib/Autom4te/General.pm (getopt): Use a more GNUish error
17658 message on invalid options.
17659 * bin/autom4te.in (parse_args): Don't use
17660 Autoconf::General::getopt with non valid options.

17678 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Don't create
17679 package.m4, since is really depends upon configure.ac, not
17681 * doc/autoconf.texi (testsuite Scripts): Adjust.
17682 * tests/Makefile.am (package.m4): New.
17683 EXTRA_DIST it since its a source.
17685 2002-01-06 Akim Demaille <akim@epita.fr>
17687 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Move the AC_SUBST
17688 of PACKAGE_NAME, PACKAGE_TARNAME, PACKAGE_VERSION, PACKAGE_STRING,
17689 and PACKAGE_BUGREPORT from here...
17690 (_AC_INIT_DEFAULTS): to here, since it is unrelated to the
17692 (_AC_INIT_PREPARE): AC_DEFINE these symbols.
17693 * lib/autotest/general.m4: Use AT_PACKAGE_*, not PACKAGE_*.
17694 (AT_INIT): No longer catch `^PACKAGE_(BUGREPORT|STRING)$'.

17711 sometimes needing writable input.
17713 2001-12-17 Jim Meyering <meyering@lucent.com>
17715 * doc/autoconf.texi (New Macros): Tweak wording.
17717 2001-12-14 Akim Demaille <akim@epita.fr>
17719 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): We cleaning up the
17720 trailing files, don't apply `-rf' to files which might not be
17721 created by configure (core, core.*, and *.core), but just `rm -f'.
17722 Suggested by Jonathan Kamens.
17724 2001-12-14 Aaron M. Ucko <amu@alum.mit.edu>
17726 * lib/autoconf/general.m4: Avoid duplicates in `$ac_configure_args'.

17730 * Makefile.am (MAINTAINERCLEANFILES): Remove configure.
17732 2001-12-13 Peter Eisentraut <peter_e@gmx.net>
17734 * lib/autoconf/status.m4 (_AC_SRCPATHS): Rename buildpath to
17735 abs_builddir, top_buildpath to abs_top_builddir, srcpath to
17736 abs_srcdir, top_srcpath to abs_top_srcdir.
17737 (_AC_OUTPUT_FILES): Adjust.
17738 * NEWS, doc/autoconf.texi, lib/autoconf/autotest.m4,
17739 * tests/atspecific.m4, tests/autoreconf.in, tests/tools.at,
17740 * tests/wrappl.in, tests/wrapsh.in: Adjust.
17742 2001-12-12 Steven G. Johnson <stevenj@alum.mit.edu>
17744 * lib/autoconf/fortran.m4 (_AC_PROG_F77_V_OUTPUT): Fix failed
17745 C/Fortran linking on HP/UX, by extracting the Fortran library
17746 search path from the LPATH line in the $F77 -v output.
17748 2001-12-12 Kevin Ryde <user42@zip.com.au>
17750 * doc/autoconf.texi (File Descriptors): Use a clearer layout for the
17751 forbidden file descriptors table.
17753 2001-11-26 Akim Demaille <akim@epita.fr>
17755 * bin/autoscan.in (%c_keywords): Build it at top level.
17756 Map to 1 in order to simplify its uses.
17758 2001-11-26 Akim Demaille <akim@epita.fr>
17760 * bin/autoscan.in (&scan_c_file, &scan_sh_file, &scan_makefile):
17761 Remove $filepath, useless.
17762 (&scan_makefile): Don't remove the $(FOO), ${FOO} and @FOO@
17763 variables, they are really part of the tokens.
17764 Split the input line on spaces and then look for tokens.
17765 Now autoscan ceases to ask for AC_PROG_LEX for the package Bison
17766 because of `lex$U.$(OBJEXT)'.
17767 (&scan_files): Use "@list" instead of join.
17768 * doc/Makefile.am (CLEANFILES): Add *.fns.
17770 2001-11-26 Akim Demaille <akim@epita.fr>

17773 Remove, replaced by...
17774 * tests/wrappl.in: Be common for all the Perl executables.
17775 In particular autoscan and autoheader want -I.
17776 * configure.ac: Adjust.
17777 * lib/autoscan/headers: errno.h is portable.
17779 2001-11-26 Akim Demaille <akim@epita.fr>
17781 * bin/autoscan.in (used): New.
17784 2001-11-26 Akim Demaille <akim@epita.fr>
17786 * bin/autoscan.in (&scan_c_file): Better parsing of CPP
17788 (&scan_sh_file): Remove a duplicate pattern.
17789 (&check_configure_ac): Use long options.

17795 Before, having a line containing the opening of a multi line
17796 comment made the whole line be ignored.
17798 2001-11-26 Akim Demaille <akim@epita.fr>
17800 * doc/autoconf.texi (Using an Autotest Test Suite): New.
17801 (testsuite Scripts): Be one of its subsection.
17802 (Autotest Logs): New.

17806 Test groups are now run two directories deeper.
17808 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Replace srcdir,
17809 top_srcdir and top_builddir with at_srcdir, at_top_srcdir and
17811 * lib/autotest/general.m4 (AT_INIT): Compute srcdir,
17812 top_srcdir, builddir and top_builddir.
17813 Use `at_*dir' relatively to the directory containing the
17814 suite, use `*dir' when relatively to the current group dir.
17816 2001-11-25 Joseph S. Myers <jsm28@cam.ac.uk>
17818 * doc/autoconf.texi, TODO, lib/autoconf/fortran.m4,
17819 lib/autoconf/functions.m4, lib/autoconf/headers.m4,
17820 tests/atgeneral.m4, tests/tools.at, tests/atspecific.m4: Fix
17823 2001-11-22 Alexandre Duret-Lutz <duret_g@epita.fr>
17825 * doc/autoconf.texi (Using System Type): Add an example of `case
17826 $host' usage so people quit using `case $target' everywhere.
17828 2001-11-22 Akim Demaille <akim@epita.fr>
17830 * doc/autoconf.texi (Installation Directory Variables): Englishoes
17831 spotted by Jim Meyering.
17833 2001-11-16 Paul Eggert <eggert@twinsun.com>
17835 This patch implements a `long double' suggestion by Oliver Kiddle.
17837 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C)): Make the array
17838 static, to catch errors if the value isn't known at compile-time
17839 and the compiler supports dynamic arrays. Change its name from
17840 `_array_' to `test_array' to avoid potential name clashes.
17841 (AC_C_LONG_DOUBLE): Make it a compile-time test, not a run-time
17842 test. Do not define HAVE_LONG_DOUBLE if `long double' is no
17843 better than double. Catch a bug in GCC 2.95.2 x86.
17844 * doc/autoconf.texi (C Compiler): Document the above.
17847 2001-11-13 Akim Demaille <akim@epita.fr>
17849 * tests/m4sh.at (LINENO): Protect from autom4te's substitution by
17851 * tests/tools.at: Don't protect dnl, AT_DATA_M4SH does.
17853 2001-11-13 Akim Demaille <akim@epita.fr>
17855 * lib/autotest/general.m4 (AT_INIT): After having run the test
17856 group, go back to the initial directory, not to at_suite_dir.
17858 2001-11-13 Akim Demaille <akim@epita.fr>
17860 * tests/atspecific.m4 (AT_DATA_M4SUGAR, AT_DATA_M4SH)
17861 (AT_DATA_AUTOCONF): Also protect @&t@ from autom4te.
17862 (AT_CHECK_AUTOCONF, AT_CHECK_AUTOHEADER): Pass no --include
17864 (AT_CHECK_CONFIGURE): Use absolute paths.
17865 (_AT_CHECK_AC_MACRO): Create aclocal.m4 with AC_STATE_SAVE in it.
17866 The problem is still the old one: there is no means in M4 (that I
17867 know about) to create a defining macro, because there is no means
17868 to create `$1' etc., therefore, the defining macro ``swallows''
17869 all the arguments meant to the defined macro.
17871 2001-11-13 Akim Demaille <akim@epita.fr>
17873 * tests/atspecific.m4 (AT_DATA_AUTOCONF): New.
17874 (AT_CONFIGURE_AC): Output the definition of AC_STATE_SAVE in
17876 * tests/aclocal.m4: Remove, as it is no longer used.
17878 2001-11-13 Akim Demaille <akim@epita.fr>
17880 * lib/autotest/general.m4: Change `tests?' into `groups?' in
17881 variable names when referring to a single test group, or to
17882 `suite' when referring to the whole test suite.
17883 `at_last_test' is removed: m4 compute at_format itself.
17884 (at_stdout, at_stder1, at_stderr): New variables.
17885 (AT_CHECK): Use them.
17887 2001-11-13 Akim Demaille <akim@epita.fr>
17889 * lib/autotest/general.m4 (AT_INIT): Be sure to put `.', relative,
17891 Create `testsuite.dir/003/run' instead of `testsuite.003'.
17892 Do it as soon as a test fails, don't wait till the end of the test
17894 Don't remove $as_me.[0-9]*, since these files no longer exist.
17896 2001-11-13 Akim Demaille <akim@epita.fr>
17898 * tests/tools.at: Use absolute paths, since we are no longer run
17901 2001-11-13 Akim Demaille <akim@epita.fr>
17903 Now that tests are running in their own private dir, there is no
17904 need to list the files to remove at the end of tests groups.
17906 * lib/autotest/general.m4 (_AT_CLEANUP_FILE, AT_CLEANUP_FILES):
17907 (AT_data_files, at_data_files): Remove.
17908 (AT_CLEANUP, AT_DATA): Simplify.
17910 Remove the group dir if !debug && !failed.
17911 * tests/atspecific.m4: Adjust.
17913 2001-11-13 Akim Demaille <akim@epita.fr>
17915 Start a new layout for Autotest: `testsuite' creates
17916 `testsuite.dir' in which the at-check-line etc. files are to be
17917 found, and `testsuite.dir/003' where the test group 3 is run.
17919 * lib/autotest/general.m4 (AT_INIT): at_tests_dir,
17920 at_check_line_file, at_format, at_test_normalized, at_group_dir
17922 Create the directories.
17923 Use absolute paths for at- files.
17924 (AT_CHECK): Adjust.
17926 2001-11-11 Michael Matz <matz@kde.org>
17928 * m4sugar.m4 (_m4_foreach): Make it linear instead quadratic.
17930 (m4_car): Properly quote arguments.
17932 2001-11-13 Akim Demaille <akim@epita.fr>
17934 * tests/aclocal.m4 (AC_STATE_SAVE): s/LIBOBJS/LIB@&t@OBJS/ to cope
17935 with stricter rules on LIBOBJS.
17937 2001-11-12 Paul Eggert <eggert@twinsun.com>
17939 * lib/autoconf/c.m4 (AC_C_PROTOTYPES): Define __PROTOTYPES too.
17940 * doc/autoconf.texi (C Compiler): AC_C_PROTOTYPES now defines
17943 2001-11-12 Akim Demaille <akim@epita.fr>
17945 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT): Use AC_CHECK_FUNCS.
17947 2001-11-12 Akim Demaille <akim@epita.fr>
17949 * lib/autoconf/c.m4, lib/autoconf/fortran.m4,
17950 * lib/autoconf/functions.m4, lib/autoconf/general.m4,
17951 * lib/autoconf/headers.m4, lib/autoconf/libs.m4,
17952 * lib/autoconf/programs.m4, lib/autoconf/specific.m4,
17953 * lib/autoconf/types.m4: When invoking AC_DEFINE and friends,
17954 specify to what the macro should be defined (typically to 1).
17956 2001-11-12 Akim Demaille <akim@epita.fr>
17958 * lib/autoconf/functions.m4 (AC_FUNC_STRTOD): AC_SUBST POW_LIB.
17961 2001-11-12 Akim Demaille <akim@epita.fr>
17963 * lib/autoconf/programs.m4 (_AC_PROG_LEX_YYTEXT_DECL): Use
17964 AC_TRY_EVAL to run $LEX, not AC_TRY_COMMAND. This validates the
17965 definition used by Automake where LEX is +/- "${missing} lex" and
17966 `missing' itself contains variables.
17968 2001-11-12 Akim Demaille <akim@epita.fr>
17970 * lib/autotest/general.m4 (AT_INIT): Push KILL at the end.
17971 Now that M4sh pushes BODY, the comments were output at the end of
17974 2001-11-08 Akim Demaille <akim@epita.fr>
17976 * bin/autoreconf.in (&autoreconf): Run aclocal before tracing, so
17977 that we can trace macros from aclocal.m4.
17978 Trace AC_PROG_LIBTOOL, not AM_PROG_LIBTOOL, since the latter is
17979 obsoleted, and redirect to the former anyway.
17980 Reported by Ralf Corsepius.
17982 2001-11-08 Akim Demaille <akim@epita.fr>
17984 * bin/autoreconf.in (&autoreconf): AC_CONFIG_SUBIDRS are to be
17985 processed only if present.
17986 * tests/torture.at (Configuring subdirectories): Use autoreconf
17987 instead of successive calls to autoconf.
17988 Add a nonexistent subdirectory to exercise the patch above.
17989 Reported by Ralf Corsepius.
17991 2001-11-08 Kevin Ryde <user42@zip.com.au>
17993 * doc/autoconf.texi (Limitations of Usual Tools): Note HP-UX cc
17994 doesn't accept .S files.
17996 2001-11-07 Akim Demaille <akim@epita.fr>

18000 (_AC_LIBOBJ): s/LIBOBJS/LIB@&t@OBJS/.
18001 * bin/autom4te.in (warn_forbidden): New.
18002 (handle_output): Use it.
18003 Read m4_pattern_forbid with messages.
18005 2001-11-05 Akim Demaille <akim@epita.fr>
18007 * bin/autom4te.in (--normalize): Remove.
18008 * lib/autom4te.in: Adjust.
18010 2001-11-05 Akim Demaille <akim@epita.fr>
18012 * tests/Makefile.am (testsuite): Rename this target as...
18013 ($(TESTSUITE)): this.
18016 2001-11-05 Alexandre Duret-Lutz <duret_g@epita.fr>
18018 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): When removing
18019 the --prefix option, also remove it's argument.
18021 2001-11-05 Akim Demaille <akim@epita.fr>
18023 * doc/autoconf.texi (testsuite Invocation): Update.
18024 (Writing testsuite.at): Update.
18026 2001-11-03 Akim Demaille <akim@epita.fr>

18030 2001-11-03 Akim Demaille <akim@epita.fr>
18032 * lib/Autom4te/General.pm: (&catfile, &canonfile)
18033 (&file_name_is_absolute): New, wrappers around routines from
18035 Use and export them.
18036 (&find_configure_ac): Optionally take a directory where to look at.
18037 * bin/autoreconf.in (&parse_args): Trim the configure.ac part of
18039 Default @ARGV to `.', not find_configure_ac.
18040 (&autoreconf): Argument is a directory.
18041 Trace AC_CONFIG_SUBDIRS and schedule the subdirs for autoreconf'ing.
18042 * doc/autoconf.texi (autoreconf Invocation): Update.
18044 2001-11-03 Akim Demaille <akim@epita.fr>
18046 * lib/Autom4te/General.pm (@export_vars, @export_subs)
18047 (@export_forward_subs): New.
18048 Add basename, dirname, and fileparse.
18050 * bin/autoreconf.in (&autoreconf): Fix call to fileparse.
18051 Don't look for aclocal flags if we already know aclocal is not
18053 Move aclocal.m4t only if it exists.
18054 Reported by Ezra Peisach.
18056 2001-11-03 Akim Demaille <akim@epita.fr>
18058 * bin/autoreconf.in (&parse_args): Work only on the configure.ac
18059 passed on command line, defaulting to ./configure.ac if present.
18060 (&maybe_autoreconf, File::Find): Remove, unused.
18061 (&autoreconf): If autoconf is not used, don't try to trace.
18063 2001-11-02 Akim Demaille <akim@epita.fr>
18065 * configure.ac: Bump to 2.52g.
18067 2001-11-02 Akim Demaille <akim@epita.fr>
18071 2001-11-02 Akim Demaille <akim@epita.fr>

18074 * config/lispdir.m4: Update from masters.
18075 * configure.ac: Bump to 2.52f.
18077 2001-11-02 Akim Demaille <akim@epita.fr>
18079 * bin/autoreconf.in (&autoreconf): Set `$aclocal_flags' to ''.
18080 Don't run aclocal when aclocal.m4 is not from aclocal.
18082 Don't run libtoolize and gettextize if --install is not given.
18084 2001-11-01 Paul Eggert <eggert@twinsun.com>
18086 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): _AS_CR_PREPARE needs to
18087 be invoked before _AS_LINENO_PREPARE.
18088 (_AS_LINENO_PREPARE): Use as_cr_digits and as_cr_alnum rather
18089 than character ranges.
18091 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Fix NLS before
18092 invoking AS_BASENAME. Set the locale variables to 'C' if
18093 possible, as POSIX requires this to get the traditional
18095 * doc/autoconf.texi (Special Shell Variables): Describe the above.
18097 2001-10-31 Paul Eggert <eggert@twinsun.com>
18099 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): Do not surround body
18100 with {}, as that triggers a bug in Bash 2.05.
18102 (_AS_LINENO_PREPARE): Use Sed rather than
18103 Awk. Fix the sed prepass to work even if there are multiple
18104 instances of $LINENO on the same line. Do not substitute for
18105 other variables like $LINENOT. Do not check file dates; such a
18106 check is unreliable on sufficiently fast machines, and removing
18107 the check makes the code simpler and more reliable. Check for
18108 output and chmod failures.
18110 * doc/autoconf.texi (Special Shell Variables): Document

18122 provided, while it is optional.
18123 * configure.ac: Adjust.

18128 lib/Autom4te/Struct.pm:
18129 Require Perl 5.005_03 instead of just 5.005, as some tests fail
18132 * doc/autoconf.texi (Special Shell Variables): Document some
18133 more LINENO gotchas, particularly with respect to the Awk+Sed hack.
18135 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): New macro.
18136 (_AS_LINENO_PREPARE): Use it instead of shell eval, since
18137 eval $LINENO is not portable in practice.

18156 Rename ac_cv_func_strerror_r_works to ac_cv_func_strerror_r_char_p,
18157 and rename HAVE_WORKING_STRERROR_R to STRERROR_R_CHAR_P, since
18158 POSIX decided to standardize on the int flavor of strerror_r.
18159 Always do char* test, as there's no reason not to.
18160 Assign to a char* var, to catch strerror_r that returns int*.
18162 * doc/autoconf.texi (Particular Functions):
18163 Document the above changes. Also, document the fact that
18164 AC_FUNC_STRERROR_R defines HAVE_DECL_STRERROR_R.

18188 * bin/autoheader.in ($localdir, $m4, $SIMPLE_BACKUP_SUFFIX):
18190 * bin/autoreconf.in (&autoreconf): Do not run gettextize when
18191 `intl' is already present, as it refuses unless --force.
18192 (&parse_args): Use -I, --include instead of the old Autoconf
18194 ($localdir, $autoconf_dir): Remove.

18219 configure.ac being studied.
18221 2001-10-18 Paul Eggert <eggert@twinsun.com>
18223 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Cast sizeof to unsigned

18230 (AS_BASENAME): Use 'basename' if that works; then try 'expr';

18234 contains white space.
18235 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR):

18292 2001-10-08 Akim Demaille <akim@epita.fr>

18613 2001-09-22 Akim Demaille <akim@epita.fr>
18615 Rely on `$LINENO' when possible instead of `__oline__'.

18618 `$LINENO' support replacement when not supported.
18619 (_AS_CR_PREPARE, _AS_TR_CPP_PREPARE, _AS_TR_SH_PREPARE): Invoke

18657 be used instead of ':'.
18658 * lib/autotest/general.m4: Replace occurrences of ':' in

18664 arguments. Fixed a typo.
18666 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
18668 * man/Makefile.am (.x.1): Use @PATH_SEPARATOR@, not ':' to set up
18669 $PATH. Also set AUTOM4TE_CFG, so we can process autom4te properly.
18671 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
18673 * bin/autoscan.in: Add 'exec-perl-if-not-run-by-perl'.

18682 * lib/Autom4te/XFile.pm (open): Simplified the error message (we
18683 already have $file). Set output files to binary mode (helps avoid
18684 CR issues on DOSish systems).
18686 2001-09-19 Akim Demaille <akim@epita.fr>
18688 * lib/autotest/general.m4: Englishoes.
18689 From Tim Van Holder and Alexey Mahotkin.
18691 2001-09-18 Paul Eggert <eggert@twinsun.com>
18693 * doc/autoconf.texi (Common Shell Constructs): New node,
18694 documenting AS_DIRNAME.
18695 (Limitations of Usual Tools): Refer to it when discussing dirname.
18696 Also, update discussion of POSIX standard to reflect latest draft.
18698 * lib/autoconf/c.m4:
18699 (AC_LANG_INT_SAVE(C)): Also support negative values, down to LONG_MIN.
18701 * lib/autoconf/general.m4 (_AC_COMPUTE_INT_COMPILE):
18702 Do not pass a first argument with leading '-'
18703 to expr, by parenthesizing initial integers that might be negative.
18705 * doc/autoconf.texi (Particular Functions): AC_FUNC_GETPGRP
18706 now merely checks whether it is an error to pass an argument
18709 * lib/autoconf/functions.m4 (_AC_FUNC_GETPGRP_TEST): Remove.
18710 (AC_FUNC_GETPGRP): Don't bother with a runtime test. Just check
18711 whether it is a (compile-time) error to pass an argument to
18712 getpgrp. This simpler test supports the revised documentation,
18713 and is all that AC_FUNC_GETPGRP's users really need.
18715 2001-09-18 Akim Demaille <akim@epita.fr>
18717 * doc/autoconf.texi (Limitations of Make) <$<>: New.

18727 * tests/m4sh.at: Ensure that AS_DIRNAME handles '/', '//' and '///'
18729 Add test for AS_BASENAME.
18730 * lib/m4sugar/m4sh.m4: Fix AS_BASENAME so that it passes the previous
18731 added test. It now correctly handles /1/2/3/, returning '3' not ''.
18732 Added AS_BASENAME_SED to make the interface the same as AS_DIRNAME.
18733 * tests/base.at: Fixed the expected responses. The old ones were
18735 * lib/autoconf/general.m4: Fixed AC_PREFIX_PROGRAM, it now behaves as
18736 the documentation claims it should (and how it behaved in 2.13).
18738 2001-09-18 Akim Demaille <akim@epita.fr>
18740 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): No INIT-CMDS in
18741 the AC_CONFIG_COMMANDS invocation.
18742 This also solves the name clash problems.
18743 Don't set the package's ID.
18744 * lib/m4sugar/Makefile.am (version.m4): Revamp.
18745 No longer to be shipped.
18746 (version.in): Remove.
18747 * lib/m4sugar/m4sugar.m4, lib/autoconf/general.m4,
18748 * lib/autoconf/status.m4: Adjust.
18749 Use `m4_PACKAGE_STRING'.
18750 * lib/autotest/general.m4 (AT_INIT): N-th signature change: now
18751 the only optional argument is the name of the test suite.
18752 Expect `package.m4' to define the package signature.
18753 * lib/autom4te.in (Autotest): Add `package.m4?'.
18754 * tests/Makefile.am (package.m4): New.
18755 * tests/suite.at: ifnames is a victim.
18757 2001-09-18 Akim Demaille <akim@epita.fr>
18759 * lib/autom4te.in (Autoconf): Preselect AM_CONDITIONAL,
18760 AC_LIBSOURCE, AC_CONFIG_FILES.
18761 * lib/autotest/general.m4 (AT_INIT): Don't abort when a tested
18762 program version string doesn't match the package's.
18763 * lib/autoconf/general.m4 (AC_CACHE_VAL): Reestablish the space

18768 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):
18769 Allow expression to return any value that can fit into unsigned long

18774 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):
18775 Always include <stdio.h> and <stdlib.h>. Evaluate
18776 the expression in an extra function before these includes. Call
18777 fprintf "%d" only after ensuring the argument is of type 'int'.
18778 Reported by Wayne Chapeskie <waynec@spinnaker.com>.
18780 2001-09-17 Paul Eggert <eggert@twinsun.com>
18782 Fix bug reported by Paul Townsend on AIX 4.3.3.0 with CFLAGS=-O4
18783 or CFLAGS=-O5. In that case, the linker has a relaxed view of
18784 fatal errors, and AC_CHECK_LIB causes it to include libraries even
18785 when they don't exist.
18787 * lib/autoconf/headers.m4 (AC_HEADER_DIRENT): Use AC_SEARCH_LIBS,
18788 not AC_CHECK_LIB, so that we don't use -ldir or -lx if we don't
18791 * lib/autoconf/specific.m4 (AC_ISC_POSIX): Replace the old, crufty
18792 version with the version used by fileutils 4.1, except use
18793 AC_SEARCH_LIBS, not AC_CHECK_LIB, so that we don't use -lcposix if
18796 * doc/autoconf.texi (AC_ISC_POSIX): Describe new behavior.
18798 2001-09-13 Akim Demaille <akim@epita.fr>

18838 * lib/autotest/general.m4 (AT_INIT): Create and remove
18839 `$as_me.[0-9]+' instead of `debug-[0-9]+.sh', so that multiple
18840 test suites can cohabit.
18842 2001-09-13 Akim Demaille <akim@epita.fr>
18844 * tests/mktests.sh: Don't output banners for empty test files.

18896 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Don't pass

18899 * lib/autoconf/programs.m4 (AC_SHELL_PATH_WALK): Use PATH_SEPARATOR.

18950 2001-09-05 Akim Demaille <akim@epita.fr>
18952 Be ready to handle filenames as stupid as `dnl.at', for if even
18953 the maintainer is dumb enough to do that...
18955 * lib/autotest/general.m4 (AT_SETUP, AT_LINE): Demonstrates your
18956 excellence in M4 quotation: consider `__file__' is active.
18958 And BTW, when invoking m4, pass the --include in the right order:

19037 2001-08-31 Akim Demaille <akim@epita.fr>
19039 * man/Makefile.am (.x.1): We really have to pass
19040 autom4te_perllibdir.
19042 2001-08-31 Akim Demaille <akim@epita.fr>
19044 * lib/autotest/general.m4 (AT_INIT): Don't pass all the args to
19045 debug scripts, in particular passing explicitly listed tests to

19050 * bin/autom4te.in (&parse_args): Strip `.' from `@include'.
19051 * bin/autoupdate.in: Use --include, -I, and --force, -f, too.
19052 Use directly autom4te, not autoconf.

19095 * tests/atspecific.m4 (AT_CHECK_AUTOHEADER): Now autoheader says
19096 `autoheader: `config.hin' is created'.
19097 * tests/tools.at (Syntax of the Perl scripts): Check autoheader.
19099 2001-08-31 Akim Demaille <akim@epita.fr>

19107 Map --localdir, --autoconf-dir onto it.
19108 Forward autom4te's options instead of interpreting them.

19110 There is no such envvar since the inception of autom4te.cfg.

19138 * tests/atlocal.in: Remove all the obscure envvar manipulations.
19140 * tests/atspecific.m4, tests/tools.at: Passing --localdir is
19141 indeed related to running the test suite, while passing

19145 * tests/autoscan: New.
19146 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): Don't

19165 2001-08-29 Akim Demaille <akim@epita.fr>

19632 autom4te.cache (it's a directory, not a file.
19633 * Makefile.am: Ditto (but maintainer-clean-local).
19635 2001-08-15 Akim Demaille <akim@epita.fr>
19637 * bin/autom4te.in (@m4_warning): New.
19638 (&handle_m4): Use it.
19639 * tests/m4sugar.at (m4_warn): Pass `-f' to autom4te to ensure the
19640 warnings are issued at each run.
19641 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): M4sugar
19642 is in the src tree.

19719 magic values from an object file when cross-compiling.
19720 Based on code by Guido Draheim <Guido.Draheim@gmx.de>.
19722 2001-08-10 Akim Demaille <akim@epita.fr>
19724 * bin/autom4te.in (&handle_output): Don't use `grep' with side
19726 Suggested by Russ Allbery.
19728 2001-08-10 Ralf Corsepius <corsepiu@faw.uni-ulm.de>
19730 * lib/autoconf/general.m4 (_AC_OUTPUT_SUBDIRS): Propagate the
19731 current $prefix to the sub-configures.
19733 2001-08-09 Tim Van Holder <tim.van.holder@pandora.be>
19735 * lib/autoconf/lang.m4: Ignore *.xSYM when looking for an executable
19736 extension (needed on BeOS). Reported by Guido van Rossum.
19738 2001-08-09 Akim Demaille <akim@epita.fr>
19740 * bin/autom4te.in ($icache): Load it only if older than autom4te.
19742 2001-08-07 Akim Demaille <akim@epita.fr>
19744 * lib/autotest/general.m4 (AT_INIT): All the `at-*' are to be
19746 (at-setup-line): Huh? Be a variable `at_setup_line', not a file.
19747 No need to remove the files before and after the each test, before
19748 each test and at the end of the suite is enough.
19749 Display only the children `times', not the shell's.
19750 If the test failed or was skipped, at-times is not available.
19752 2001-08-07 Akim Demaille <akim@epita.fr>
19754 Always produce testsuite.log, including when there are no
19755 failures. This helps getting information on skipped tests, and
19756 duration of the tests. Err, implement the latter btw.
19758 * lib/autotest/general.m4 (AT_INIT): Set up fd 6 for the log.
19759 Dump information on the first run of each test.
19760 (AT_CLEANUP): Create `at-times' containing the duration of the
19763 2001-08-07 Akim Demaille <akim@epita.fr>
19765 The use of `dumpstat' revealed that `len' was used although it
19766 should not. m4_text_wrap was using it, but in the Autoconf world
19767 where it is legal. Hence (i) test M4sh in its own world, not
19768 Autoconf's, and (ii), ahem, fix the bug :)
19770 * lib/autotest/general.m4: Be sure the set good quotes, as tracing
19771 does not like `' instead of [].
19772 (AT_INIT): Forbid `^_?AT_'.
19773 And don't output such tokens.
19774 * tests/Makefile.am (CLEANFILES): Add `script', `script.s4g',
19775 `script.as', and `autom4te.cache'.
19776 Remove `empty' and `macro' which are no longer used.
19777 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): New.
19778 * tests/m4sugar.at: Use it.
19779 * lib/m4sugar/m4sugar.m4: Use `m4_len' not `len'.
19781 2001-08-07 Akim Demaille <akim@epita.fr>

19787 * bin/autom4te.in (handle_output): Typo in quadrigraph substitution.
19789 2001-08-04 Akim Demaille <akim@epita.fr>
19791 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA, AC_FUNC_ERROR_AT_LINE)
19792 (AC_FUNC_FSEEKO, AC_FUNC_OBSTACK): Use AC_LANG_IFELSE, not
19794 * lib/autoconf/headers.m4 (AC_HEADER_MAJOR): Likewise.

19796 (AC_F77_MAIN): Likewise.
19798 2001-08-04 Akim Demaille <akim@epita.fr>
19800 Don't rely on M4sugar outputting the patterns in files, since we
19801 might process the output _without_ running m4, hence without these
19804 * lib/m4sugar/m4sugar.m4 (m4_init): No need for `m4_tmpdir'.
19805 * bin/autom4te.in (@Request::includes): Remove, unused.
19806 (@Request::source): Rename as...
19807 (@Request::input): this.

19812 (m4_pattern_forbid, m4_pattern_allow): Adjust for tracing only.
19814 2001-08-04 Akim Demaille <akim@epita.fr>
19816 `autoconf && autoheader' is sped up. Now, speed up `autoheader &&
19817 autoconf', i.e., in addition to caching traces, cache the output.
19819 * bin/autom4te.in (Request::cache): Rename as...
19820 (Request::id): this.
19821 ($cache, $icache, $tcache, $ocache): New.
19822 (&handle_m4): Save M4 output in the cache instead of $tmp.

19824 (&up_to_date_p): Check that the output cache is up to date too.
19825 (top level): Run `&handle_m4' iff force or the cache is invalid.
19826 Run `&handle_output' if the output cache is more recent.
19828 2001-08-04 Akim Demaille <akim@epita.fr>
19830 * bin/autom4te.in ($force): New.
19831 (&parse_args, &print_usage): -f, --force is a new option.
19832 (&handle_output): CPP directives might have spaces after `#'.
19833 (&parse_args): The first file only can be frozen.
19835 2001-08-04 Akim Demaille <akim@epita.fr>
19837 Don't let autom4te compute the `include' traces several times:
19838 first check that the trace cache file is up to date, and then
19839 compare its timestamp with that of the output.
19841 * bin/autom4te.in, bin/autoupdate.in, bin/autoscan.in: Normalize
19842 the preamble. Don't require 5.005 as Autom4te::General does it,
19843 and better yet (use `use', not `require'!).
19844 * lib/Autom4te/Struct.pm: Rename the last occurrences of
19845 Class::Struct as Autom4te::Struct.
19846 * lib/Autom4te/General.pm (File::stat): Use it.
19847 (&mtime): New, export it.
19848 * bin/autom4te.in: Use it.
19849 Declare `$req' is invalid if it is outdated.

19855 must be proposed to the users.
19857 * bin/autom4te.in (@required_trace): Remove.
19859 (&parse_args, &print_usage): -p, --preselect is a new option.

19902 * bin/autom4te.in (&handle_output): Remember of the first
19903 occurrence of a possibly undefined macro, not the last.

19905 the appear in the output.
19906 * lib/autoconf/Makefile.am (autoconf.m4f): List its dependencies.
19907 * tests/tools.at (autoconf: forbidden tokens, basic)
19908 (autoconf: forbidden tokens, exceptions): No longer sort
19909 autoconf's stderr, as it is now deterministic.
19910 Check that `dnl' is caught.

19933 * bin/autoupdate.in, bin/autoscan.in: Improve error messages accuracy.
19934 * bin/autoupdate.in (File::Compare, File::Copy): Use them instead of
