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

646 DJGPP fix: remove both conftest and conftest.exe.
647 The DJGPP compiler may create both `a.out' and `a.exe' without -o,
648 and both `conftest' and `conftest.exe' with `-o conftest', but not
649 with `-o conftest.exe'.
650 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_O): Also remove
651 `conftest' without $ac_exeext suffix.

654 * lib/autoconf/general.m4 (AC_SITE_LOAD, AC_CACHE_LOAD): Do not
655 load the cache or site file if it is `/dev/null', as DJGPP treats

5482 Suggested by Ralf Wildenhues.
5484 2008-03-02 Jim Meyering <meyering@redhat.com>
5486 Don't infloop upon "make dist".
5487 * GNUmakefile: Merge from coreutils.
5488 * Makefile.am (dist-hook): Inject .tarball-version into tarball,
5490 * configure.ac (AC_INIT): Use .tarball-version, not .version.

5510 * tests/tools.at (autom4te and whitespace in file names)
5511 (autotools and whitespace in file names): Use them.
5512 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
5513 Cover more potentially problemtic file names. Use the new
5516 Properly handle funny file names for headers in config.status.
5517 The test suite did not cover this bug because the code was not
5518 quoting properly the arguments of `rm -f' (which "fails" silently)
5519 as well as the arguments of `diff' (whose output was redirected to
5520 /dev/null so we couldn't see its error message).
5521 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Properly quote the
5522 file names passed to `rm' and `diff'.
5523 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
5524 Add a regression test.

5633 not just when atconfig was located.
5635 Add 'testsuite -C dir'.
5636 * lib/autotest/general.m4 (_AT_ARG_OPTION): Move missing argument
5638 (AT_INIT) <PARSE_ARGS_END>: ...here, since -k always takes
5640 <DEFAULTS>: Delay computation of variables based on $at_dir...
5641 <PREPARE_TESTS>: ...to here, since -C can change $at_dir.
5642 <TESTS>: Re-invoke via absolute name, since -C may be in effect.
5643 <PARSE_ARGS>: Parse new option.
5644 <HELP_TUNING>: Document it.
5645 * tests/autotest.at (Choosing where testsuite is run): New test
5647 (Keywords and ranges): Add test for missing -k argument.
5648 * NEWS: Document this.
5649 * doc/autoconf.texi (testsuite Invocation): Likewise.
5651 2008-01-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5653 * build-aux/config.guess, build-aux/config.sub,
5654 build-aux/texinfo.tex: Sync from gnulib.
5655 * doc/fdl.texi, doc/make-stds.texi, doc/standards.texi:
5658 2008-01-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5660 * doc/autoconf.texi (Particular Programs): Do not mention the
5661 Autoconf version in which the AC_PROG_INSTALL change was done.
5662 Suggested by Paul Eggert.
5664 2008-01-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5666 Fix --help=recursive with multiple AC_CONFIG_SUBDIRS.
5667 * lib/autoconf/general.m4 (_AC_INIT_HELP): If, for recursive help
5668 mode, we change to the source directory, also set $ac_pwd so we
5669 do not go back to the build tree for the next config subdir.
5670 * tests/torture.at (Deep Package): Extend test to contain two
5671 config subdirs on the top level.
5673 Fix parallel `maintainer-check'.
5674 * Makefile.am (maintainer-check-tests): Depend on `all'.
5675 Use `$(MAKE) $(AM_MAKEFLAGS)' instead of plain `make'.
5676 * tests/Makefile.am (maintainer-check-c++, maintainer-check-posix):
5678 (maintainer-check): Serialize the testsuite runs.

5702 2008-01-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5704 * tests/Makefile.am (noinst_SCRIPTS): Renamed from
5705 check_SCRIPTS. Building the wrappers for `all' allows help2man
5706 to use them for the manpages.
5707 Report by Benoit Sigoure.
5709 * bin/autoreconf.in: Discard stderr for $autoconf/$aclocal --help.
5711 2007-12-16 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5713 Fix some write failure cases in Autotest.

5724 (_m4_defun_pro_outer, _m4_defun_epi, _m4_defun_epi_outer)
5725 (m4_require): Use m4_do, not m4_join.
5727 Fix some whitespace tests on cygwin.
5728 * tests/tools.at (autom4te and whitespace in file names): Restore
5729 font-lock. Create $TMPDIR before it might be used.
5731 Fix spurious testsuite failure with M4 1.4.11.
5732 * tests/local.at (AT_CHECK_M4): Cater to new m4 error message.
5734 Optimize AC_REQUIRE.
5735 * lib/m4sugar/m4sugar.m4 (m4_expansion_stack_push, _m4_defun_pro)
5736 (_m4_defun_pro_outer, _m4_defun_epi, _m4_defun_epi_outer)
5737 (m4_require): Avoid extra macro calls.
5739 2007-12-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5741 * tests/torture.at (srcdir): Fix quoting.
5743 Do not pass top_srcdir to configure scripts in testsuite.
5744 * tests/autotest.at (srcdir propagation): Copy install-sh to
5746 (my only test): Drop setting of `top_srcdir'.
5747 * tests/base.at (Input/Output): Likewise.
5748 * tests/local.at (AT_CONFIGURE_AC): Copy install-sh,
5749 config.guess, and config.sub to test source tree.
5750 Drop AC_CONFIG_AUX_DIR setting.
5751 (AT_CHECK_CONFIGURE): Drop setting of `top_srcdir'.
5752 * tests/torture.at (Substitute a 2000-byte string): Drop
5753 AC_CONFIG_AUX_DIR setting, copy install-sh to test source tree.
5754 (Substitute a newline, datarootdir workaround): Likewise.
5755 (Define a newline): Adjust for linenumber changes in configure.ac.
5756 * tests/foreign.at (Libtool): Adjust comment to reflect changes.
5758 * tests/semantics.at (AC_PATH_PROGS_FEATURE_CHECK): Skip test
5759 if `pwd` contains whitespace.
5761 Quote $abs_top_srcdir in tests.
5762 * tests/local.at (AT_CHECK_PERL_SYNTAX): Likewise.
5763 * tests/tools.at (Syntax of the shell scripts): Likewise.
5765 * tests/m4sh.at (LINENO): Quote $0.
5767 Fix testsuite program wrapper for whitespace in `pwd`.
5768 The problem here is that the usual mantra is that command
5769 variables can contain arguments, thus we cannot just escape
5770 $AUTOCONF, $AUTOM4TE etc. The compromise is to put the
5771 $top_builddir/tests directory early in $PATH, so that the
5772 wrappers are found by their plain name.
5773 * tests/wrapper.as: Put $testdir early in $PATH.
5774 (AUTOCONF, AUTOHEADER, AUTOM4TE): Set to plain command names.
5776 Proper config.status --file/--header and $srcdir escaping.
5777 * lib/autoconf/status.m4 (_AC_OUTPUT_MAIN_LOOP): Quote special
5778 characters in $ac_file_inputs.
5779 (_AC_OUTPUT_FILE, _AC_OUTPUT_HEADER): eval $ac_file_inputs
5781 * tests/torture.at (datarootdir workaround): Adjust.
5782 (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS): Extend test.
5784 Fix Autotest for whitespace in `pwd`.
5785 * lib/autotest/general.m4 (AT_INIT)
5786 <at_func_create_debugging_script, Driver Loop>:
5787 Quote $at_group_dir.
5788 * tests/autotest.at (whitespace in absolute testdir): New test.
5790 * lib/autom4te.in: Quote @datadir@.
5792 Proper file name escaping in Autoconf programs and Perl modules.
5793 This includes escaping of characters special to the shell
5794 as well as special to Perl, e.g., leading `<' or `>'.
5795 For example, when $file starts with `>', `open ">$file"'
5796 wrongly tries to append to a different file.
5797 * bin/autoconf.as: Fix quoting for autom4te options.
5798 * lib/Autom4te/General.pm (shell_quote): New function, taken
5799 from coreutils, written by Jim Meyering.
5801 * bin/autom4te.in (files_to_options, handle_m4): Use shell_quote
5803 * bin/autoreconf.in (parse_args): Likewise.

5805 * bin/autoupdate.in (main): Likewise.
5806 * bin/autoheader.in: Likewise, fixing old insufficient escaping.
5807 * bin/ifnames.in: Likewise, XFile usage fixes.
5808 * tests/tools.at (autom4te and whitespace in file names): Extend
5809 test. Test twice, with special characters allowed on w32, and the
5810 rest. Test leading and trailing whitespace, for `open_quote'.
5811 (autotools and whitespace in file names): New, analogous test.
5812 Reported by Paul Eggert and Benoit Sigoure, additional suggestions
5813 by Russ Allbery and Eric Blake.
5816 * lib/Autom4te/Channels.pm, lib/Autom4te/Configure_ac.pm,
5817 lib/Autom4te/Struct.pm, lib/Autom4te/XFile.pm: Likewise.
5818 * lib/Autom4te/FileUtils.pm (open_quote): New function.
5819 (update_file, contents): Use it.
5821 * Makefile.am (autom4te-update): Rewrite for git.
5823 2007-12-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5825 * doc/autoconf.texi (autom4te Invocation, Autom4te Cache): Fix typos.
5827 Fix copyright years.
5828 * Makefile.am, doc/install.texi, lib/autoconf/fortran.m4,
5829 lib/autoconf/lang.m4, lib/freeze.mk: Likewise.
5831 2007-12-04 Eric Blake <ebb9@byu.net>
5833 Manually resync with gnulib, since 'make cvs-update' no longer works.
5834 * build-aux/config.guess: New upstream version.

5839 * doc/Makefile.am (TEXINFO_TEX): Add.
5841 2007-11-27 Paul Eggert <eggert@cs.ucla.edu>
5843 Fix AC_C_BIGENDIAN bug caused by new awk method of substitution.
5844 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Don't comment out the
5845 #undef as this runs afoul of our new way of creating config.h.
5846 Problem reported by Jim Meyering in
5847 <http://lists.gnu.org/archive/html/autoconf-patches/2007-11/msg00164.html>.

5851 Fix autom4te for unusual characters in input file names.
5852 * bin/autom4te.in (files_to_options): Quote active characters
5854 * tests/tools.at (autom4te and white space in file names):
5857 * doc/autoconf.texi (Limitations of Usual Tools) <awk>:
5858 Document that Tru64 awk always splits $0.
5860 2007-11-24 Stepan Kasal <kasal@ucw.cz>
5862 * lib/autotest/general.m4 (AT_INIT): Do not extract the
5863 `#AT_STOP_...' line at the end of each test.
5865 2007-11-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5867 * lib/autotest/general.m4 (AT_INIT): For awk line number
5868 extraction script, ensure `$at_group' has a defined value
5869 even for the empty set, and properly quote its usage inside
5872 2007-11-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5874 * doc/autoconf.texi (Shell Functions): New chapter. Document
5875 IRIX sh $0 issue in functions, move content from ...
5876 (Portable Shell): ... here.
5877 (Shell Script Compiler): Note that shell functions are not
5878 totally unportable any more.
5880 2007-11-22 Stepan Kasal <kasal@ucw.cz>
5881 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5883 * lib/autotest/general.m4 (AT_INIT): Exit awk script after
5884 extracting the line numbers of the last needed test.
5886 2007-11-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5888 * lib/autotest/general.m4 (AT_INIT) <at_func_create_debugging_script>:
5891 2007-11-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5893 Fix IRIX testsuite debugging failures: $0 in functions.
5894 * lib/autotest/general.m4 (AT_INIT) <at_func_create_debugging_script>:
5895 Do not use $0 inside a function, as IRIX sh will set that to the
5896 function name rather than the script invocation name.
5898 2007-11-19 Paolo Bonzini <bonzini@gnu.org>
5899 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5901 * lib/autotest/general.m4 (at_func_test): Use cached line numbers
5902 to extract test scripts.
5903 (AT_INIT): Extract and cache test script line numbers.
5905 2007-11-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5907 * lib/autotest/general.m4: Revert 2007-11-15 patch and
5908 subsequent fixups; the awk -> here-document conversion trashes
5909 performance too much with AIX sh.
5911 2007-11-18 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5913 * tests/local.at: Do not test m4, perl with AT_TESTED.
5915 Diagnose and guard against write errors dealing with config.status.
5916 The general idea is this: all write failures from `configure'
5917 writing `config.status' are indicated by $ac_write_error, which
5918 is only checked at the end. This is safe because config.status
5919 code is not executed before the file is complete. Other write
5920 failures, be they inside config.status, or in sub shell/awk
5921 scripts spawned from configure or config.status, typically need
5922 earlier checking, as their results are used right afterwards.
5923 * lib/autoconf/status.m4 (AC_OUTPUT): Initialize `ac_write_fail'
5924 before writing config.status, check afterwards.
5925 (_AC_OUTPUT_FILES_PREPARE, _AC_OUTPUT_FILE)
5926 (_AC_OUTPUT_HEADERS_PREPARE,_AC_OUTPUT_CONFIG_STATUS):
5927 Set `ac_write_error' for write failures to config.status. Barf
5928 upon write failures to temporary files.
5929 Adjust note about closing and reopening the here-document.
5930 (_AC_OUTPUT_HEADER, _AC_OUTPUT_LINK, _AC_OUTPUT_COMMAND)
5931 (_AC_OUTPUT_MAIN_LOOP): Likewise, adjust note about closing and
5932 reopening the here-document.
5933 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
5934 Ensure `ac_write_error' does not escape into config.status.
5935 Also, add a couple of code paths not yet exercised in the test
5936 suite: a config file with input from stdin, and a config header
5938 Suggestion for catching write errors by Bruno Haible.
5940 2007-11-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5942 Avoid error with Tru64 awk and testsuite lines with many words.
5943 * lib/autotest/general.m4 (AT_INIT): In the awk script that
5944 reads the testsuite, set the field separator to an unusual value,
5945 in order to not run over the limit of 199 fields. Tru64 4.0D awk
5946 even splits the input if $i, i>0, was never accessed in the script.
5948 Revert 2007-10-17 change.
5949 * TODO: Multiline args in config files and headers mean something
5950 different and are not fixed, see

5958 AC_*_TOOL does not canonicalize the prefix
5959 * doc/autoconf.texi (Generic Programs): Do not say that
5960 the *_TOOL macros canonicalize, they simply use the `host_alias'.
5962 2007-11-16 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5964 Diagnose write errors in config.status instantiations.
5965 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE)
5966 (_AC_OUTPUT_HEADER, _AC_OUTPUT_MAIN_LOOP): Bail out
5968 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
5969 Extend test to also check for some write error failures, using...
5970 <AT_CHECK_CONFIG_CREATION_NOWRITE>: ...this new macro.
5971 Report by Bruno Haible.
5974 * lib/autotest/general.m4 (AT_INIT) <at_func_log_failure>: Fix
5976 (_AT_CHECK): Use less indentation, to save space.
5978 2007-11-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5980 Add witness macro for @top_build_prefix@ substitution.
5981 * lib/autoconf/status.m4 (_AC_HAVE_TOP_BUILD_PREFIX): New macro.
5982 (_AC_OUTPUT_FILE): Mention it here.
5984 2007-11-15 Paolo Bonzini <bonzini@gnu.org>
5985 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5987 * lib/autotest/general.m4 (at_func_test): Remove.
5988 (AT_INIT): Pre-extract test groups into separate files.
5989 (AT_CLEANUP): Source pre-extracted file instead of calling at_func_test.
5990 Remove at-test-source files together with the $at_group_dir.
5991 * tests/autotest.at (Long test source lines): New test.
5993 2007-11-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5995 Shell functions and variables may share a namespace.
5996 * doc/autoconf.texi (Portable Shell): Mention Solaris sh
5999 2007-11-14 Paul Eggert <eggert@cs.ucla.edu>
6001 * lib/autoconf/types.m4 (_AC_TYPE_LONG_LONG_SNIPPET): Make comment match
6004 2007-11-14 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6006 * lib/autoconf/status.m4: Fix a couple of comment typos.
6008 * lib/m4sugar/m4sh.m4 (AS_TMPDIR): Use $as_me, not $me.
6010 2007-11-13 Jim Meyering <meyering@redhat.com>
6012 Clean up the rule to create "expr".
6013 * tests/Makefile.am (expr): Don't redirect directly to target.
6014 Redirect just once, not for each echo statement.
6015 Use $@, not literal "expr".
6017 2007-11-13 Paul Eggert <eggert@cs.ucla.edu>
6019 Don't worry about preprocessor when testing long long.
6020 See: http://lists.gnu.org/archive/html/bug-gnulib/2007-11/msg00075.html
6021 * doc/autoconf.texi (Preprocessor Arithmetic): New section.
6022 (AC_TYPE_LONG_LONG_INT, AC_TYPE_UNSIGNED_LONG_LONG_INT):
6023 These no longer check for preprocessor flaws.
6024 * lib/autoconf/types.m4 (_AC_TYPE_LONG_LONG_SNIPPET):
6025 Do not check for preprocessor flaws.
6027 2007-11-13 Jim Meyering <meyering@redhat.com>
6029 Adapt dependencies, now that a version change doesn't modify configure.ac
6030 * GNUmakefile: Remove "make clean" kludge.
6031 * lib/m4sugar/Makefile.am (version.m4): Depend on Makefile, not
6033 Don't redirect directly to target.
6034 Use $@, not literal "version.m4".
6036 2007-11-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6038 * doc/autoconf.texi (Making testsuite Scripts): Document
6039 ":;{" shorthand as in previous patch.
6041 2007-11-12 Paul Eggert <eggert@cs.ucla.edu>
6043 * doc/autoconf.texi (Limitations of Builtins): Document problem
6044 with { ... } a bit more clearly. Suggest ":;{" as a shorthand
6046 * lib/m4sugar/Makefile.am (version.m4): Detect 'echo' failure.
6047 Use ":;{" shorthand.
6048 * tests/Makefile.am ($(srcdir)/package.m4): Likewise.
6050 2007-11-12 Jim Meyering <meyering@redhat.com>
6052 Add more non-srcdir build support.
6053 * GNUmakefile (dummy): Split a long line.
6054 Add -v option to autoreconf invocation.
6056 Remove the autoreconf-provided INSTALL, so that we regenerate it.
6057 * GNUmakefile (dummy): Remove INSTALL.
6059 Remove racy commands to build scripts in bin/ and tests/.
6060 * man/Makefile.am (.x.1): Now that scripts in bin/ and tests/
6061 are guaranteed to be built, remove the rules that tried to build
6062 them. Before, with a parallel build, these rules could lead to
6063 two processes writing tests/wrapper.in concurrently.
6065 Build in man/ only *after* building in bin/ and tests/.
6066 * Makefile.am (SUBDIRS): The man-page-creation process runs $(MAKE)
6067 in both bin/ and tests/.
6069 Accommodate non-srcdir build-from-checkout.
6070 * build-aux/git-version-gen: Require an additional parameter: $srcdir.
6071 Use git's --git-dir=$srcdir/.git option.
6072 Add quotes, in case tarball_version_file contains shell meta-characters.
6073 * GNUmakefile (_curr-ver): Pass $(srcdir) to git-version-gen.
6074 * configure.ac: Pass "." to git-version-gen.
6076 Avoid spurious test failures due to version skew.
6077 * GNUmakefile (dummy): Run $(MAKE) clean after autoreconf -i.
6079 2007-11-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6081 Avoid warnings about conftest.dSYM directories on Mac OS X Leopard.
6082 * lib/autoconf/general.m4 (_AC_LINK_IFELSE, _AC_RUN_IFELSE):
6083 Remove conftest.dSYM directory.
6084 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT)
6085 (_AC_LANG_PROGRAM_C_, _AC_FC_MAIN, __AC_FC_NAME_MANGLING):
6086 Remove `conftest.*' recursively.
6087 * lib/autoconf/lang.m4 (AC_LINK_IFELSE): Likewise.
6088 * lib/autoconf/specific.m4 (_AC_SYS_LARGEFILE_MACRO_VALUE):
6090 (_AC_COMPILER_OBJEXT_REJECT): Reject *.dSYM.
6092 Report and analysis by Jeff Squyres and Peter O'Gorman.
6094 2007-11-12 Benoit Sigoure <tsuna@lrde.epita.fr>
6096 Fix typos in variable names.
6097 * tests/semantics.at (test for AC_CHECK_LIB): s/at_m/ac_m/.
6099 2007-11-11 Benoit Sigoure <tsuna@lrde.epita.fr>
6101 Document that $((expression)) is not portable.
6102 * doc/autoconf.texi (Shell Substitutions): Here.
6104 2007-11-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6106 Ignore configure --help* errors due to LINENO-impaired shells.
6107 * tests/torture.at (Configuring subdirectories, Deep Package):
6108 In the --help* tests in read-only trees, make `.' temporarily
6109 writable again for the `stderr' file, and ignore errors due to
6110 the attempt to write configure.lineno.
6111 Report by Patrick Welche.
6113 2007-11-10 Jim Meyering <meyering@redhat.com>
6115 Generate package.m4 in build-dir, not srcdir.
6116 * tests/Makefile.am (package.m4): Adjust target.
6117 Don't redirect directly to $@.
6118 (CLEANFILES): Add package.m4.
6119 ($(TESTSUITE)): Depend on just-built package.m4, not the one
6121 When running $(AUTOTEST), search "." before searching $(srcdir).
6123 Avoid a race condition that would make parallel "distclean" fail.
6124 * tests/Makefile.am (distclean-generic): Replace the default,
6125 automake-provided rule with an identical one, but with an additional
6126 dependency on distclean-local. Simply adding the dependency would
6127 cause automake not to emit the rule at all.
6128 * BUGS: Building with -jN works, now.
6130 Distribute git-version-gen.
6131 * Makefile.am (EXTRA_DIST): Add build-aux/git-version-gen,
6132 since GNUmakefile is distributed, and requires it for dist* rules.
6134 Remove two more generated files from version control.
6135 * INSTALL: Remove generated file.
6136 * lib/autoscan/autoscan.list: Remove generated file.
6138 2007-11-09 Paul Eggert <eggert@cs.ucla.edu>
6140 * GNUmakefile (PATH): Remove stray apostrophes; they become
6141 part of PATH, which isn't wanted here.
6143 2007-11-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6145 New config files output variable `top_build_prefix'.
6146 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Substitute
6148 * doc/autoconf.texi (Preset Output Variables): Document it.
6150 Report by Bob Friesenhahn.
6152 Avoid expr for arithmetic evaluation if the shell accepts $((...)).
6153 * lib/autotest/general.m4 (AT_INIT) <at_func_arith>: New
6154 function, to parametrize arithmetic with expr vs. the shell.
6155 Use it where possible.
6156 Suggestion by Benoit Sigoure.
6158 2007-11-03 Benoit Sigoure <tsuna@lrde.epita.fr>
6160 Adjust the documentation of autotest WRT atlocal.
6161 * doc/autoconf.texi (Making testsuite Scripts): It is not necessary,
6162 when using Automake, to write a rule to produce atlocal, since it's
6163 an AC_CONFIG_FILES. Mention that atlocal.in needs to be
6164 distributed, not atconfig.in.
6166 2007-11-04 Eric Blake <ebb9@byu.net>
6168 Update list information.
6169 * README: Mention new autoconf-commit list.
6170 * doc/autoconf.texi (Introduction): Mention autoconf-commit list.
6172 2007-11-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6174 * lib/autoconf/functions.m4 (_AC_FUNC_MALLOC_IF): Fix comment typo.
6176 * lib/m4sugar/Makefile.am (version.m4): Another bash bug workaround.
6178 * build-aux/.gitignore: Ignore mkinstalldirs.
6180 * doc/autoconf.texi (autoreconf Invocation): Fix an underfull line.
6182 2007-11-03 Jim Meyering <meyering@redhat.com>
6184 s/-/./ in snapshot version string: 2.61a-256-8b556 -> 2.61a.256-8b556
6185 * build-aux/git-version-gen: This syncs from coreutils.
6187 Adjust the build procedure so "make check" works reliably.
6188 * README-hacking: Include an extra step between "make" and
6189 "make check" to ensure that the latter passes.
6191 Use just-built tools, when possible.
6192 * GNUmakefile (PATH): Set and export here, ...
6193 (dummy): ... rather than here.
6195 2007-11-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6196 and Andreas Schwab <schwab@suse.de>
6198 * tests/Makefile.am ($(srcdir)/package.m4): Work around bash
6201 2007-11-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6203 * configure.ac (AC_PREREQ): Require version 2.60, for
6204 AC_PROG_SED, AC_PROG_GREP.
6206 2007-11-02 Benoit Sigoure <tsuna@lrde.epita.fr>
6207 and Jim Meyering <meyering@redhat.com>
6208 and Andreas Schwab <schwab@suse.de>
6209 and Eric Blake <ebb9@byu.net>
6211 Document a bug in GNU Bash with compound commands and redirections.
6212 * doc/autoconf.texi (Limitations of Builtins): Mention that GNU
6213 Bash doesn't properly set $? when `{ ... } >/bad' fails, and give
6216 2007-11-03 Eric Blake <ebb9@byu.net>
6218 Support m4 1.4.5 in testsuite.
6219 * tests/torture.at (Define a newline): Exclude line numbers in
6221 Reported by Ralf Wildenhues.
6223 2007-11-03 Jim Meyering <meyering@redhat.com>
6225 Remove automake-provided files from version control.
6226 * build-aux/elisp-comp: Remove file.
6227 * build-aux/install-sh: Remove file.
6228 * build-aux/missing: Remove file.
6229 * build-aux/mdate-sh: Remove file.
6230 * build-aux/.gitignore: New file.
6231 Suggestion from Ralf Wildenhues.
6233 2007-11-03 Eric Blake <ebb9@byu.net>
6235 Adjust version comparison to account for git snapshot numbers.
6236 * lib/m4sugar/m4sugar.m4 (_m4_version_unletter): Also treat - as a
6237 component separator.
6238 * doc/autoconf.texi (Number processing Macros)
6239 <m4_version_compare>: Document this change.
6240 * tests/m4sugar.at (m4@&t@_version_compare): Test it.
6242 2007-10-30 Bruno Haible <bruno@clisp.org>
6244 * lib/autoconf/types.m4 (_AC_TYPE_LONG_LONG_SNIPPET): New macro,
6245 extracted from AC_TYPE_LONG_LONG_INT and AC_TYPE_UNSIGNED_LONG_LONG_INT.
6246 (AC_TYPE_LONG_LONG_INT, AC_TYPE_UNSIGNED_LONG_LONG_INT): Use it.
6247 Fixes problem with Sun C 5.[0-8] in 32-bit mode, reported in
6248 <http://lists.gnu.org/archive/html/autoconf-patches/2007-10/msg00210.html>
6249 Suggested by Paul Eggert.
6251 2007-10-28 Jim Meyering <meyering@redhat.com>
6253 * README-hacking: Autoconf, Automake, and Perl are required to build.
6254 List Gzip and Tar separately. Suggested by Ralf Wildenhues.
6256 2007-10-28 Jim Meyering <meyering@redhat.com>
6258 README-hacking: Recommend running autoreconf -vi.
6259 * GNUmakefile (dummy): Use autoreconf -i, with appropriate PATH,
6260 so that we use just-built tools when they're available.
6261 Suggestions from Ralf Wildenhues.
6263 2007-10-28 Jim Meyering <meyering@redhat.com>
6265 Make inter-release --version output more useful.
6267 Now, each unofficial build has a version "number" like 2.61a-19-58dd,
6268 which indicates that it is built using the 19th change set
6269 (in _some_ repository) following the "v2.61a" tag, and that 58dd
6270 is a prefix of the commit SHA1.
6271 * build-aux/git-version-gen: New file.
6272 * configure.ac: Run it to set the version.
6273 (AM_INIT_AUTOMAKE): Don't check NEWS here.
6274 * Makefile.am (dist-hook): Arrange so that .version appears only
6275 in distribution tarballs, never in a checked-out repository.
6276 * .gitignore: Add .version here, too. Just in case.
6277 * tests/Makefile.am ($(srcdir)/package.m4): Depend on Makefile,
6278 not configure.ac, now that the version number changes automatically.
6280 Ensure that $(VERSION) is up to date for dist-related targets.
6281 * GNUmakefile: Arrange to rerun autoconf, if the version reported by
6282 git-version-gen doesn't match $(VERSION), but only for dist targets.
6284 2007-10-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6286 Fix `Deep Package' failure with a configure script early in PATH
6287 * tests/torture.at (Deep Package): Add `.' early in PATH.

6297 * README-hacking: New file: how to build from just-checked-out sources.
6299 2007-10-23 Eric Blake <ebb9@byu.net>
6301 Improve corner case of m4_expand.
6302 * lib/m4sugar/m4sugar.m4 (m4_expand, _m4_expand): Rewrite more

6316 problem reported by Bruno Haible in
6317 <http://lists.gnu.org/archive/html/bug-autoconf/2007-10/msg00027.html>.
6319 2007-10-22 Eric Blake <ebb9@byu.net>
6321 * doc/autoconf.texi (Particular Types): Mention bug in HP-UX 11.00
6324 2007-10-22 Paul Eggert <eggert@cs.ucla.edu>
6326 Don't check for bug in HP-UX 11.00 cpp.
6327 * lib/autoconf/types.m4 (AC_TYPE_UNSIGNED_LONG_LONG_INT):
6328 Use -1ull rather than -1u, since that causes problems with gnulib; see
6329 <http://lists.gnu.org/archive/html/bug-gnulib/2007-10/msg00329.html>.
6331 2007-10-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

6347 escaping of backslash in here-documents.
6349 Fix `Deep Package' test failure on FreeBSD.

6351 unnecessarily. Do not try running `/bin/sh configure' with a
6352 configure script to be found in $PATH, if the shell does not do
6353 this resolution. Fixes test failure on FreeBSD.
6355 Fix config header generation with AIX awk.
6356 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS_PREPARE): In awk
6357 script, use helper array D_is_set, as `" 0"' does not evaluate
6358 to true for AIX awk.
6360 2007-10-21 Eric Blake <ebb9@byu.net>

6395 * lib/autotest/general.m4 (BANNERS): New named diversion.
6396 (TESTS_END): Diversion no longer used.
6397 (AT_INIT) <at_func_banner, BANNERS>: Factor all banners into a
6398 shell function, which prints only as needed, using an associative
6399 array of banner text from a special diversion.
6400 <PARSE_ARGS_END>: No longer need awk to find banners.
6401 <TESTS>: Banners are no longer processed by main driver loop, so
6402 we no longer need case statement.
6403 (AT_BANNER): Rewrite to populate new diversion.
6404 (AT_SETUP): Each test invokes its own banner. No output is needed
6405 to the TESTS diversion.

6432 duplication bug by using new macro.
6433 (AT_INIT) <at_tested>: Restore newline separators. Invoke tested
6434 programs with stdin redirected, so programs that don't
6435 understand --version won't try to behave interactively.
6436 * tests/autotest.at (Tested programs): Catch this bug.

7538 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't look
7539 for a.* when searching for executables, as this prevents users
7540 from having files like a.c. Problem reported by Ralf Wildenhues in:
7541 http://lists.gnu.org/archive/html/autoconf-patches/2007-04/msg00029.html

7552 * NEWS: Document recent changes to AC_CHECK_ALIGNOF, AC_CHECK_SIZEOF,
7553 AC_CHECK_TYPE, AC_CHECK_TYPES.
7554 * doc/autoconf.texi (Generic types): C types must be type-names
7555 (the C terminology), not type-ids (the C++ term). C++ types
7556 must not be anonymous.
7557 * lib/autoconf/types.m4 (_AC_CHECK_TYPE_NEW): Remove special case
7558 for C++; this drops support for anonymous struct and union types,
7559 which were problematic anyway.

7575 * doc/autoconf.texi (Generic Types): Document the restrictions
7576 on types imposed by AC_CHECK_TYPE, AC_CHECK_TYPES.
7577 (Generic Compiler Characteristics): AC_CHECK_SIZEOF now works
7578 with objects too. Document the restrictions on its use.
7579 Document the restrictions on AC_CHECK_ALIGNOF's type argument.
7580 * lib/autoconf/types.m4 (_AC_CHECK_TYPE_NEW):
7581 For C, just try sizeof (TYPE) and sizeof ((TYPE)); if the former
7582 works but the latter doesn't, then it's a valid type.
7583 This lets people use function types and so forth.
7584 For C++ there doesn't seem to be a simple solution, so leave it alone.
7585 (AC_CHECK_SIZEOF): Allow argument to be a variable.
7586 (AC_CHECK_SIZEOF, AC_CHECK_ALIGNOF): Don't bother to invoke
7587 AC_CHECK_TYPE; that wasn't documented or necessary.
7589 2007-04-11 Stepan Kasal <kasal@ucw.cz>
7591 * lib/autoconf/general.m4 (_AC_LINK_IFELSE): Skip AS_TEST_X
7592 when cross-compiling.
7594 2007-04-11 Stepan Kasal <kasal@ucw.cz>
7596 * doc/autoconf.texi (External Software): Fix a typo in the

7604 2007-04-06 Paul Eggert <eggert@cs.ucla.edu>
7606 * doc/autoconf.texi (Particular Types): AC_C_LONG_DOUBLE is now
7607 obsolescent. Suggested by Bruno Haible.
7608 * NEWS: Document this.
7610 2007-03-29 Paul Eggert <eggert@cs.ucla.edu>
7612 * doc/autoconf.texi (Here-Documents, Limitations of Builtins):
7613 (Limitations of Usual Tools): Don't say "older" if Solaris 10 by
7614 default still has the problem. Problem reported by Bruce Korb.
7616 2007-03-28 Stepan Kasal <kasal@ucw.cz>
7617 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7619 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Fix a

7635 checks for unsigned long long int.
7637 2007-03-19 Paul Eggert <eggert@cs.ucla.edu>
7639 * doc/autoconf.texi (Limitations of Usual Tools): Warn about other
7640 nonstandard grep R.E. escape sequences.
7642 2007-03-17 Jim Meyering <jim@meyering.net>
7644 * doc/autoconf.texi: Adjust grammar around use of "heuristics".
7645 (Limitations of Usual Tools): Also list \< and \>, and mention that
7646 HP-UX's grep, like the one from Solaris, does not support that syntax.
7648 2007-03-09 Stepan Kasal <kasal@ucw.cz>
7650 * doc/autoconf.texi (Specifying Names): `--host' does not
7651 change the build type.
7653 2007-03-05 Paul Eggert <eggert@cs.ucla.edu>
7655 * doc/autoconf.texi (C Compiler): Warn that AC_C_BIGENDIAN
7656 suggests AC_CONFIG_HEADERS.

7666 * tests/semantics.at (AC_C_BIGENDIAN): Don't reject hosts that have
7667 universal binaries. Problem reported by Elias Pipping.
7669 2007-02-27 Paul Eggert <eggert@cs.ucla.edu>
7671 * NEWS: AC_C_BIGENDIAN now supports universal binaries a la Mac OS X.
7672 * doc/autoconf.texi (C Compiler): Document this. There is a new
7673 extra argument ACTION-IF-UNIVERSAL.
7674 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Implement this.
7675 Add support for Solaris-style _LITTLE_ENDIAN and _BIG_ENDIAN.
7676 Reindent for sanity's sake.
7678 2007-02-24 Eric Blake <ebb9@byu.net>

7686 2007-02-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7688 * lib/autotest/general.m4 (AT_INIT): With --clean, return exit
7689 status of rm so we know when it failed.
7690 If cleaning of test dir failed before running the test, warn.
7691 Output the line separator in verbose mode before the warning
7692 to make clear the warning belongs to the following test.
7694 2007-02-08 Paul Eggert <eggert@cs.ucla.edu>
7696 * doc/autoconf.texi (Parentheses): Mention problem with (( in

7703 errors introduced in last change.
7705 2007-02-07 Paul Eggert <eggert@cs.ucla.edu>
7707 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Prefer \r to

7719 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Redirect
7720 input from /dev/null in awk test, so even Solaris /usr/bin/awk

7757 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Also
7758 AC_SUBST([MKDIR_P]), so that Automake < 1.10 will pick up its
7759 trace, if a package uses AC_PROG_MKDIR_P explicitly. The actual
7760 substitution will still be done by the special code.
7761 Report by Jim Meyering.
7763 * doc/autoconf.texi (File System Conventions): Mention that
7764 $PATH_SEPARATOR is for the build system only.

7784 * lib/autoconf/programs.m4 (AC_PROG_SED): When closing a pipe
7785 early on the reader side, drop stderr of the input to avoid
7786 `broken pipe' error output; this may happen even with shell
7787 builtin `echo' of some bash versions. Reports by Ian Macdonald
7788 <iamacdo@telkomsa.net> and Sam Sexton <Sam.Sexton@reuters.com>.
7790 2007-01-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

7803 http://lists.gnu.org/archive/html/autoconf-patches/2007-01/msg00077.html
7804 * doc/autoconf.texi (Signed Overflow Examples): Give more
7805 discussion about the allow_superuser_privileges example,
7806 and change it a bit to make things clearer.
7807 (Optimization and Wraparound): Clarify whether the compiler
7808 will generate an infinite loop for the example derived from
7809 Autoconf's mktime test.
7810 (Signed Overflow Advice): Say that -ftrapv is meant for debugging.
7811 Also, clarify unsigned multiplication overflow.
7813 2007-01-04 Eric Blake <ebb9@byu.net>
7815 * bin/Makefile.am (RELEASE_YEAR): New macro.
7816 (edit): Use it to supply correct copyright year to scripts.
7817 * bin/autoconf.as (version): Use it.
7818 * bin/autoheader.in ($version): Likewise.
7819 * bin/autom4te.in ($version): Likewise.
7820 * bin/autoreconf.in ($version): Likewise.
7821 * bin/autoscan.in ($version): Likewise.

7825 2007-01-02 Paul Eggert <eggert@cs.ucla.edu>
7827 * doc/autoconf.texi (Integer Overflow): Revised based on today's
7828 feedback. The most important changes document what happens when
7829 you convert an out-of-range value to a signed integer type, and
7830 say that (sum < a) != (b < 0) reliably detects overflow when sum =
7833 * doc/autoconf.texi (Integer Overflow): Greatly expand and
7834 rewrite, taking notions from the recent discussion on the gcc and
7835 autoconf mailing lists; please see
7836 http://lists.gnu.org/archive/html/autoconf-patches/2006-12/msg00091.html
7837 and follow the many links.
7838 (Integer Overflow Basics, Signed Overflow Examples):
7839 (Optimization and Wraparound, Signed Overflow Advice):
7840 (Signed Integer Division): New sections.
7842 2006-12-28 Steven G. Johnson <stevenj@alum.mit.edu>
7844 * lib/autoconf/general.m4 (AC_DEFINE_TRACE): Don't include
7845 preprocessor macro arguments in traced name.
7846 * doc/autoconf.texi (Defining symbols): Document longstanding
7847 support for AC_DEFINE-ing macros with arguments, and document
7848 behavior when the same variable has multiple AC_DEFINEs.
7849 * lib/autoconf/fortran.m4 (_AC_FC_WRAPPERS): Revert to the
7850 old implementation which AC_DEFINEs the FC_FUNC and FC_FUNC_
7851 macros directly, giving much shorter and simpler code.
7853 2006-12-28 Malcolm Purvis <malcolmp@xemacs.org> (trivial change)
7855 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Insert a
7856 space before "$ac_configure_args" to prevent a 'config.status
7857 --recheck' failure if ac_configure_args doesn't contain a leading
7858 space. This works around a problem with the XEmacs configure.ac,
7859 which uses the (undocumented) ac_configure_args variable
7860 inconsistently with Autoconf.
7862 2006-12-22 Paul Eggert <eggert@cs.ucla.edu>
7864 * lib/autoconf/functions.m4 (AC_FUNC_MKTIME):
7865 Include <limits.h>, and use its INT_MAX to rewrite the
7866 j loop so that it does not overflow 'int'. Problem reported by
7868 <http://lists.gnu.org/archive/html/bug-gnulib/2006-12/msg00084.html>.
7869 Play it safe by shifting left by 1 rather than multiplying by 2,
7870 as GCC is less likely to optimize this away when the value
7871 is signed (when it assumes overflow leads to undefined behavior).
7872 Also, don't assume time_t uses two's complement.
7874 2006-12-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7876 * tests/torture.at (Substitute a 2000-byte string): Avoid using
7877 a 10kB long (multi-line) string literal, OpenServer 5.0.7 ksh
7878 dumps core on it. Report by Tim Rice.

7894 --enable-* and --with-* options.
7895 * doc/autoconf.texi (Option Checking): Renamed from
7896 (Configure Option Checking). Tighten up the wording a bit.
7897 (External Software, Package Options): Cross-reference to Option
7898 Checking, and use this to shorten our section.
7899 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Prefer test -n
7900 "$x" to test "x$foo" != x.
7901 * lib/autoconf/status.m4 (AC_OUTPUT): Likewise.
7902 Don't warn if $enable_option_checking is "no".
7903 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Initialize
7904 ac_unrecognized_opts to the empty string.
7905 Don't echo the unrecognized opts, as this might mishandle
7906 backslashes or leading -.
7907 (AC_PRESERVE_HELP_ORDER): Put the --disable-option-checking
7908 usage next to the other --disable-FEATURE options in the
7911 2006-12-18 Steven G. Johnson <stevenj@alum.mit.edu>
7913 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS, _AC_INIT_PARSE_ARGS):
7914 (_AC_INIT_PARSE_ENABLE2, _AC_INIT_HELP, _AC_ENABLE_IF):
7915 Print warning for unrecognized --with and --enable options
7916 (AC_DISABLE_OPTION_CHECKING): New macro to disable warnings.
7917 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS, _AC_OUTPUT_SUBDIRS):
7918 Disable option checking when subdirs are configured.
7919 (AC_OUTPUT): If warnings are enabled, print warning about
7920 unrecognized --with and --enable options at the end of
7921 the configure output (as well as at the beginning).
7922 * doc/autoconf.texi (Option Checking): New node.
7923 Document new option warning functionality.
7925 2006-12-16 Eric Blake <ebb9@byu.net>
7927 * configure.ac (AC_INIT): Bump version, since 2.61a is released.
7928 * NEWS: Start news for current version.
7930 2006-12-15 Paul Eggert <eggert@cs.ucla.edu>
7932 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT):
7933 Define HAVE_GETMNTENT to 1, not to the empty string.
7934 Problem originally reported by Jochen Friedrich in
7935 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=403243>.
7937 This change prompted by a problem report by Andrey Simonenko in
7938 <http://lists.gnu.org/archive/html/bug-autoconf/2006-12/msg00026.html>.
7939 * doc/autoconf.texi (Defining Symbols): AC_DEFINE works for
7940 object-like macros only, in the traditional portable character
7942 * lib/autoconf/general.m4 (AC_DEFINE_TRACE_LITERAL):
7943 Warn about attempts to define things that are not identifiers.
7944 * lib/autoconf/fortran.m4 (_AC_FC_WRAPPERS): Rewrite to avoid
7945 awful hack that AC_DEFINEd macro names containing parentheses.
7947 2006-12-12 Paul Eggert <eggert@cs.ucla.edu>
7949 * doc/autoconf.texi: Undo some of the 2006-12-10 change. It was
7950 too drastic, even if Texinfo in theory requires it for info mode.
7952 (config.status Invocation): Renamed back from Recreating a
7954 (Obsolete config.status Use): Renamed back from Obsolete Recreation.
7955 (Autoconf 2.13): Renamed back from 20th-century Autoconf 2.
7957 2006-12-11 Paul Eggert <eggert@cs.ucla.edu>
7959 * NEWS: Version 2.61a.
7961 2006-12-11 Paul Eggert <eggert@cs.ucla.edu>
7962 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7964 * NEWS: Document changes with echo and printf, and the lack
7965 of limits on the total size of multi-line values of substituted
7966 variables, and the AC_FUNC_FSEEKO fix.
7968 2006-12-10 Paul Eggert <eggert@cs.ucla.edu>
7970 * doc/autoconf.texi (Writing Autoconf Input): Renamed from
7971 Writing configure.ac.
7972 (Autoconf Input Layout): Renamed from configure.ac Layout.
7973 (Recreating a Configuration): Renamed from config.status Invocation.
7974 (Obsolete Recreation): Renamed from Obsolete config.status Use.
7975 (acconfig Header): Renamed from acconfig.h.
7976 (20th-century Autoconf 2): Renamed from Autoconf 2.13.
7977 (Writing Testsuites): Renamed from Writing testsuite.at.
7978 (Autom4te Cache): Renamed from autom4te.cache.
7980 * BUGS: Remove mention of VPATH problem, since it's now documented
7981 not to be a bug in the Autoconf build procedure itself, but rather
7982 a problem with the proprietary `make' programs.
7984 * doc/autoconf.texi (Build Directories): Add a cross reference
7987 * build-aux/config.guess, build-aux/config.sub, build-aux/texinfo.tex:
7988 * doc/standards.texi: Sync from gnulib.
7990 * man/autoconf.1, man/autoheader.1, man/autom4te.1, man/autoreconf.1:
7991 * man/autoscan.1, man/autoupdate.1, man/config.guess.1:
7992 * man/config.sub.1, man/ifnames.1: Remove from CVS, since they're
7993 generated automatically.
7995 2006-12-06 Paul Eggert <eggert@cs.ucla.edu>
7997 * lib/autoconf/c.m4 (_AC_PROG_CC_C89): Also try -xc99=all, for Sun
7998 C 5.8 on Solaris 10. Using -xc99=all rather than -xc99 bypasses
7999 the buggy -xc99 option of Forte Developer 7 C on Solaris 9.
8001 2006-12-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8003 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Drop the
8004 `CEOF$ac_eof' special marker, the awk script cannot contain a
8005 line matching `^CEOF', so this is not needed any more.
8006 * tests/torture.at (Substitute a newline): Expose the `%!_!# '
8007 special marker in the test.
8009 2006-12-06 Stepan Kasal <kasal@ucw.cz>
8011 * tests/tools.at (autom4te preselections): Use `find -newer';
8012 remove one of the sleeps.
8014 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE): Make it
8015 more readable, using ...
8016 (_AC_INIT_PARSE_ENABLE2): ... this new helper macro.
8018 * doc/autoconf.texi (autoheader Invocation): Do not double-
8019 quote the parameter of `AH_BOTTOM' in the example.
8021 2006-12-05 Stepan Kasal <kasal@ucw.cz>
8023 * doc/autoconf.texi (Configuration Headers): Remove the
8024 example with multiple input files.
8025 (autoheader Invocation): Encourage `AH_BOTTOM', discouraging
8026 multiple input files.
8028 2006-12-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8030 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): When
8031 creating the awk substitution script, handle one input line at a
8032 time, so that the maximum length of a substituted (multi-line)
8033 value is not limited by the size of the sed pattern space.
8034 The trade-off is a slightly repetitive sed script.
8035 * doc/autoconf.texi (Limitations of Usual Tools): Branch labels
8036 can only have up to 7 characters, due to Solaris 10 /bin/sed.
8037 * tests/torture.at (Substitute a 2000-byte string): Increase the
8038 test with several long lines, they should not be caught by sed
8041 * tests/tools.at (autom4te preselections): New test, to flag
8042 entries missing from autom4te.cfg.
8043 Report by David Byron <dbyron@hheld.com>.
8045 * tests/torture.at (Substitute a 2000-byte string): Actually use
8046 AC_PROG_AWK, so the last change works as intended.
8047 (Substitute and define special characters): Likewise.
8048 (Substitute a newline): Likewise.
8050 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Use `$AWK'
8051 instead of `awk' consistently.
8052 (_AC_OUTPUT_CONFIG_STATUS): Initialize $AWK.
8053 * tests/torture.at (Torturing config.status): Test both the
8054 result of AC_PROG_AWK and plain awk.
8055 (Substitute a 2000-byte string): Likewise.
8056 (Substitute and define special characters): Likewise.
8057 (Substitute a newline): Likewise.
8059 2006-12-04 Paul Eggert <eggert@cs.ucla.edu>
8061 * lib/autoconf/functions.m4 (AC_FUNC_FSEEKO): Check that fseeko
8062 can be assigned to a function pointer. Problem reported by
8063 Peter Palfrader in <http://bugs.debian.org/401377>. Based on
8064 part of a patch by Ralf Wildenhues in that same bug report.
8066 2006-12-01 Paul Eggert <eggert@cs.ucla.edu>
8068 * tests/mktests.sh (ac_exclude_list): Exclude AC_FUNC_SETVBUF_REVERSED.
8069 * tests/semantics.at (AC_FUNC_SETVBUF_REVERSED): New test.
8071 2006-12-01 Eric Blake <ebb9@byu.net>
8073 * lib/autoconf/c.m4 (AC_LANG_INT_SAVE): Avoid newline, to aid in
8074 cross-compiling from cygwin to mingw.
8075 Reported by Bob Rossi. This resurrects the 2000-11-30 patch to
8076 aclang.m4, which was mistakenly removed in the 2001-09-17 patch
8077 to lib/autoconf/c.m4.
8079 2006-12-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8081 * lib/m4sugar/m4sh.m4 (_AS_ECHO_PREPARE): Use a longer test
8082 string for more reliable failure. Wrap the entire test that
8083 causes the broken Solaris printf to dump core, in a subshell,
8084 so the segmentation fault message is reliably suppressed.
8085 Fix shell expansion errors by using /usr/ucb/echo always;
8086 avoid an error on systems without it by another subshell.
8087 Avoid m4 expansion of `$1'. Set the zeroth argument of the
8088 subshell-$as_echo to `as_echo', for better error message.
8090 2006-11-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8092 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): If `BASH_ARGV' or
8093 `BASH_SOURCE' contain a newline, set them to empty, as they may
8096 2006-11-27 Paul Eggert <eggert@cs.ucla.edu>
8098 Turn AC_FUNC_SETVBUF_REVERSED into a noop. It's been obsolete for
8099 years and is too hard to maintain now. The last straw was
8100 reported by Jerker Baeck in
8101 <http://lists.gnu.org/archive/html/autoconf/2006-11/msg00102.html>.
8102 * NEWS: AC_FUNC_SETVBUF_REVERSED is now obsolete.
8103 * doc/autoconf.texi (Particular Functions): Move
8104 AC_FUNC_SETVBUF_REVERSED from here...
8105 (Obsolete Macros): ... to here. Say that it does nothing now.
8106 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
8107 Turn into (almost) a no-op.
8109 * lib/autoconf/c.m4 (AC_PROG_GCC_TRADITIONAL, AC_C_CONST):
8111 Do not recommend via AN_FUNCTION, AN_IDENTIFIER, or AN_HEADER.
8112 These macros are obsolescent and new applications shouldn't need them.
8113 * lib/autoconf/functions.m4 (AC_FUNC_CLOSEDIR_VOID, AC_REPLACE_FNMATCH):
8114 (AC_FUNC_GETLOADAVG, AC_FUNC_GETPGRP, AC_FUNC_MEMCMP):
8115 (AC_FUNC_SELECT_ARGTYPES, AC_FUNC_SETPGRP, AC_FUNC_STAT, AC_FUNC_LSTAT):
8116 (AC_FUNC_STRFTIME, AC_FUNC_SETVBUF_REVERSED, AC_FUNC_UTIME_NULL):
8117 (AC_FUNC_VPRINTF): Likewise.
8118 * lib/autoconf/headers.m4 (AC_HEADER_DIRENT, AC_HEADER_STAT):
8119 (AC_HEADER_STDC, AC_HEADER_SYS_WAIT, AC_HEADER_TIME): Likewise.
8120 * lib/autoconf/types.m4 (AC_STRUCT_TM): Likewise.
8122 * doc/autoconf.texi (Setting Output Variables): Mention that
8123 @VAR1@VAR2 has unspecified behavior. Problem reported by
8125 * NEWS: Mention this.
8127 * Makefile.am: Put only a single '#' into the copyright notice,
8128 so that it's also present in the output file. Standardize wording
8129 in makefile copyright notices to match GNU coding standards.
8130 * bin/Makefile.am: Likewise.
8131 * doc/Makefile.am: Likewise.
8132 * lib/Makefile.am: Likewise.
8133 * lib/freeze.mk: Likewise.
8134 * lib/autoconf/Makefile.am: Likewise.
8135 * lib/autoscan/Makefile.am: Likewise.
8136 * lib/autotest/Makefile.am: Likewise.
8137 * lib/m4sugar/Makefile.am: Likewise.
8138 * man/Makefile.am: Likewise.
8139 * tests/Makefile.am: Likewise.
8140 * lib/emacs/Makefile.am: Remove copyright notice; it's just a
8143 2006-11-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8145 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Fix error
8146 in the sed script that mangles the awk script: delete up to the
8147 first exclamation mark only.
8148 * tests/torture.at (Substitute and define special characters):
8151 2006-11-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8153 Rewrite config files generation: avoid quadratic growth in
8154 the number of substituted variables by using awk instead of sed
8155 for the bulk of the substitutions.
8156 * NEWS: Mention this.
8157 * doc/autoconf.texi (Setting Output Variables): `|#_!!_#|' is also
8158 forbidden in the output (and thus input) file.
8159 * lib/autoconf/status.m4 (_AC_AWK_LITERAL_LIMIT): New macro.
8160 (_AC_OUTPUT_FILES_PREPARE): Instead of several sed scripts,
8161 generate just one large awk script for substitutions,
8162 eliminating much of the earlier complexity, while adding some
8163 new complexity. Only expand the substitution templates at
8164 configure time, for smaller configure script size. If
8165 _AC_SUBST_FILES are used, test 'awk' for working getline support
8166 at config.status time. If absent, interpolate through the
8167 shell. The awk script was written with much help
8168 from Paolo Bonzini and Paul Eggert.
8169 (_AC_SED_CMD_NUM, _AC_SED_DELIM_NUM, _AC_SED_FRAG): Removed.
8170 (_AC_SED_FRAG_NUM): Likewise.
8171 (_AC_SUBST_CMDS): Renamed from...
8172 (_AC_SED_CMDS): ...this.
8173 (_AC_OUTPUT_FILE): Use _AC_SUBST_CMDS.
8174 * tests/torture.at (Substitute a 2000-byte string): Also
8175 substitute a line with 1000 words, and a variable with several
8177 (Substitute and define special characters): Test awk special
8178 characters, and put substitution input strings `@foo@' in the
8179 output, to test that no recursion happens; test several other
8180 combinations from Paolo Bonzini.
8182 2006-11-25 Paul Eggert <eggert@cs.ucla.edu>
8184 * lib/autotest/general.m4 (AT_INIT): Undo recent changes
8185 that replaced echo with AS_ECHO where this wasn't necessary.
8186 Problem reportd by Ralf Wildenhues.
8187 * lib/m4sugar/m4sh.m4 (_AS_ECHO_PREPARE): Port to Solaris 7,
8188 where "/usr/bin/printf '%s\n' S" dumps core if S is long.
8189 This is Sun bug 4206210. Problem reportd by Ralf Wildenhues.
8191 2006-11-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8193 * lib/freeze.mk (GREP): Removed, no need to initialize this.
8195 2006-11-21 Paul Eggert <eggert@cs.ucla.edu>
8197 * doc/autoconf.texi (Limitations of Usual Tools): Don't claim
8198 that traditional Awk lacks 3-arg "split". It has it.
8199 Mention that FS must be a single character, and a few other
8200 99-byte limits of traditional Awk.
8201 Mention that if (i in a) doesn't work with traditional Awk.
8203 2006-11-18 Paul Eggert <eggert@cs.ucla.edu>
8205 * tests/autotest.at (BSx641-newline in command):
8206 (BS-BS-newline in command, BSx640-newline in command):
8207 (Newline-CODE-BS-newline in command):
8208 (Single-quote-BS-newline in command):
8209 (Single-quote-newline-BS-newline in command):
8210 Use printf '%s\n' instead of echo, for portability to hosts
8211 where echo interprets backslashes. This will break on hosts
8212 that lack printf, but for now let's assume all such hosts
8213 are dead (if not, we should get reports of test failures).
8215 2006-11-17 Paul Eggert <eggert@cs.ucla.edu>
8217 'echo' has some portability problems, when given a first argument
8218 with a leading '-', or when given any argument containing '\'.
8219 Avoid using 'echo' in these cases.
8220 * bin/Makefile.am $(bin_SCRIPTS): Rewrite to avoid 'echo' entirely.
8221 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX, AC_PROG_OBJC): Likewise.
8222 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
8223 * lib/autotest/general.m4 (AT_INIT): Likewise.
8224 * bin/autoconf.as: Use AS_ECHO rather than plain echo, when the
8225 argument might be unportable.
8226 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Likewise.
8227 * lib/autoconf/erlang.m4 (AC_LANG(Erlang)): Likewise.
8228 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT):
8229 (_AC_FC_LIBRARY_LDFLAGS): Likewise.
8230 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Likewise.
8231 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE, _AC_INIT_PREPARE):
8232 (_AC_ARG_VAR_VALIDATE, AC_ARG_PROGRAM, _AC_MSG_LOG_CONFTEST):
8233 (AC_RUN_LOG, _AC_RUN_IFELSE, _AC_LIBOBJS_NORMALIZE): Likewise.
8234 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Likewise.
8235 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Likewise.
8236 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH):
8237 (AC_PROG_MAKE_SET): Likewise.
8238 * lib/autoconf/status.m4 (_AC_SRCDIRS, _AC_OUTPUT_HEADER):

8240 * lib/autotest/general.m4 (_AT_CREATE_DEBUGGING_SCRIPT, AT_INIT):
8241 (AT_CLEANUP, _AT_DECIDE_TRACEABLE, _AT_CHECK): Likewise.

8243 (_AS_BASENAME_SED, _AS_DIRNAME_SED, AS_MKDIR_P, AS_TMPDIR, AS_UNAME):
8244 (AS_TR_SH, AS_TR_CPP, AS_VAR_GET): Likewise.
8245 * bin/autoconf.as: Redo verbose flag implementation, as the old
8246 scheme wouldn't work with AS_ECHO.
8247 * lib/autotest/general.m4 (AT_INIT): Likewise.
8248 * lib/autoconf/general.m4 (AC_MSG_RESULT, AC_MSG_RESULT_UNQUOTED):
8249 Don't use ECHO_T, since ECHO_N is now reliable.
8250 * lib/autotest/general.m4 (AT_INIT): Likewise.
8251 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Use sed "$script"
8252 rather than using a here-document to put the script into a file.
8253 (_AC_DO_ECHO): Hoist the eval out of the echo, so that we can
8255 * lib/m4sugar/m4sh.m4 (AS_VAR_GET): Likewise.
8256 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Use
8257 AS_ECHO_N rather than ECHO_N and ECHO_C. This doesn't fix any
8258 bug, but we might as well stop using ECHO_N and ECHO_C internally.
8259 * lib/autotest/general.m4 (AT_SETUP): Likewise.
8260 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N): Likewise.
8261 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
8262 (_AC_OUTPUT_MAIN_LOOP): Rework echo so that it has just one
8263 operand, as AS_ECHO requires. Avoid double file name expansion.
8264 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Invoke _AS_ECHO_PREPARE.
8265 Don't set as_nl, since _AS_ECHO_PREPARE does that now.
8266 (_AS_PREPARE): Comment that _AS_ECHO_N_PREPARE is just for user code.
8267 (AS_ECHO, AS_ECHO_N, _AS_ECHO_PREPARE): New macros.
8268 * tests/c.at (AC_PROG_CPP without warnings, AC_PROG_CPP via CC):
8269 Double-quote strings that would otherwise contain M4 comments.
8270 * tests/m4sh.at (AS_ECHO and AS_ECHO_N): New test.
8272 * configure.ac (AC_INIT): Bump to 2.61a.
8275 2006-11-17 Paul Eggert <eggert@cs.ucla.edu>
8279 * configure.ac (AC_INIT): Bump to 2.61.
8282 * tests/autotest.at (Macro with backslash in a test title):
8283 Comment out for now, as this tests neither fails nor passes
8284 reliably. Problem reported by Ralf Wildenhues.
8286 2006-11-16 Paul Eggert <eggert@cs.ucla.edu>
8288 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE): Fix some typos
8289 in previous change, which caused test failures.
8291 2006-11-16 Stepan Kasal <kasal@ucw.cz>
8293 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Factor out
8294 code for --enable, --disable, --with, and --without to...
8295 (_AC_INIT_PARSE_ENABLE): ... a new macro.
8296 * doc/autoconf.texi (Package Options):
8297 * NEWS: Document that AC_ARG_ENABLE allows dots, too.
8299 2006-11-16 Paul Eggert <eggert@cs.ucla.edu>
8301 Import these changes from config via gnulib:

8352 2006-11-13 Bruno Haible <bruno@clisp.org>
8354 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): For --with, --without
8355 options, transliterate also dots to underscores.

8358 first argument may also contain dots.
8360 2006-11-09 Paul Eggert <eggert@cs.ucla.edu>
8362 * tests/mktests.sh (ac_exclude_list): Exclude AC_PROG_CXX_C_O, for
8363 benefit of platforms like Solaris+GCC where it is common to have a
8364 non-working g++ installation.
8366 2006-11-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8367 and Joel E. Denny <jdenny@ces.clemson.edu>
8368 and Paul Eggert <eggert@cs.ucla.edu>

8376 * lib/autoconf/types.m4 (AC_TYPE_LONG_LONG_INT): Set
8377 ac_cv_type_long_long_int to 'yes' instead of 'cross-compiling'.
8378 Imported from a similar patch to gnulib by Bruno Haible.

8408 (Backquote in a test title,
8409 Single-quote in a test title,
8410 Double-quote in a test title): Don't expect failure anymore.
8411 (Backslash in a test title): Put a non-whitespace character after the
8412 backslash so that Bourne shells might actually see it as an escape
8414 (Brackets in a test title,
8415 Pound in a test title,
8416 Comma in a test title,
8417 Quoted Macro in a test title,

8421 Macro with double-quote in a test title,
8422 Macro with backslash in a test title): New tests expected to fail.
8423 * tests/torture.at (#define header templates): M4-quote this title in
8424 AT_SETUP call so that no M4 code is commented inadvertently somewhere.
8425 The visible effect was a stray [] in the testsuite output.
8427 2006-10-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8429 * doc/autoconf.texi (Limitations of Builtins): Do not invoke
8430 `trap ... 0' inside a function, for AIX sh.
8432 2006-10-26 Paul Eggert <eggert@cs.ucla.edu>
8434 * tests/base.at (AC_COMPUTE_INT): Test **0** rather than 1 / 0,
8435 since powerpc-apple-darwin8-gcc-4.0.1 (Apple Computer, Inc. build
8436 5363) simply issues a warning when dividing by zero at compile
8437 time. Problem reported by Elias Pipping.
8439 2006-10-26 Eric Blake <ebb9@byu.net>
8442 * doc/autoconf.texi (Evaluation Macros): Improve the example to
8443 show effect on macros that expand with commas.

8468 2006-10-24 Paul Eggert <eggert@cs.ucla.edu>
8470 * lib/autoconf/specific.m4 (_AC_SYS_LARGEFILE_MACRO_VALUE):
8471 If FUNCTION-BODY is nonempty, use AC_LINK_IFELSE rather than
8472 AC_COMPILE_IFELSE, to work around problem with OSF/1 4.0F fseeko
8473 reported by Nelson H. F. Beebe for Coreutils 6.4.
8475 * tests/tools.at (autoconf --trace: user macros): Remove test
8476 for tracing multiline macros, since m4 1.4.7a uses a different
8477 way to number lines. Problem reported by Ralf Wildenhues.
8479 2006-10-24 Stepan Kasal <kasal@ucw.cz>

8507 * lib/autoconf/types.m4: All uses of AC_CACHE_CHECK_INT changed.
8508 * tests/base.at (AC_COMPUTE_INT): Test this, not AC_CACHE_CHECK_INT.

8553 2006-10-14 Paul Eggert <eggert@cs.ucla.edu>
8555 (Imported from Automake.)
8556 * build-aux/install-sh (posix_mkdir): Reject FreeBSD 6.1 mkdir -p -m,
8557 which incorrectly sets the mode of an existing destination
8558 directory. In some cases the unpatched install-sh could do the
8559 equivalent of "chmod 777 /" or "chmod 0 /" on a buggy FreeBSD
8560 system. We hope this is rare in practice, but it's clearly worth
8561 fixing. Problem reported by Alex Unleashed in
8562 <http://lists.gnu.org/archive/html/bug-autoconf/2006-10/msg00012.html>.
8563 Also, don't bother to check for -m bugs unless we're using -m;
8564 suggested by Stepan Kasal.

8610 2006-10-13 Stepan Kasal <kasal@ucw.cz>
8612 * doc/autoconf.texi (Autoheader Macros): Warn that the text
8613 added to the template can get mangled.
8615 2006-10-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8617 * lib/autoconf/functions.m4 (AC_FUNC_OBSTACK): In the test,
8618 include the default headers, and redefine obstack_chunk_alloc
8619 and obstack_chunk_free. Fixes false failure with glibc.
8621 2006-10-12 Paul Eggert <eggert@cs.ucla.edu>
8623 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Set as_executable_p,

8638 * lib/autoconf/specific.m4 (AC_USE_SYSTEM_EXTENSIONS): Likewise.
8640 * lib/m4sugar/m4sh.m4 (AS_TEST_X): New macro.
8641 (AS_EXECUTABLE_P): Use as_test_x rather than as_executable_p.
8642 (_AS_TEST_PREPARE): Set as_test_x rather than as_executable_p.
8643 Use a better substitute, by inspecting the output of "ls"
8644 rather than just using ":".
8645 * lib/autoconf/general.m4 (_AC_LINK_IFELSE): Use AS_TEST_X
8646 rather than AS_EXECUTABLE_P, since we needn't worry about
8647 non-regular files here.
8649 * NEWS: Autoconf-generated shell scripts no longer export BIN_SH,
8650 due to configuration hassles with this. See Tonya Underwood's report
8651 <http://lists.gnu.org/archive/html/bug-autoconf/2006-10/msg00003.html>.

8663 initialization which is not inherited through the environment
8664 (_AS_BOURNE_COMPATIBLE): ... to this new macro.
8665 (_AS_RUN): Call _AS_BOURNE_COMPATIBLE, not AS_BOURNE_COMPATIBLE.

8670 problems with mkdir -p -m.
8672 2006-10-06 Paul Eggert <eggert@cs.ucla.edu>
8674 * lib/autoconf/c.m4 (_AC_PROG_PREPROC_WORKS_IFELSE): Remove
8675 comment about ac_cpp_err; it was incorrect, and anyway
8676 ac_cpp_err is being removed below.
8677 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE): Don't
8678 set ac_cpp_err to 'yesyes' if preproc_warn_flag and werror_flag
8679 are both 'yes'. In fact, don't bother setting ac_cpp_err at all;
8681 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't log our funky tests
8682 with werror_flag and conftest.err and so forth. This is more
8683 compatible with how _AC_PROG_PREPROC_WORKS_IFELSE behaves,
8684 and anyway the user shouldn't normally want to see this gorp logged.
8685 Problem reported by Ralf Wildenhues.
8686 * lib/autoconf/lang.m4 (AC_LANG_WERROR): werror_flag's default is
8687 empty, not 'no', since the rest of the code uses 'test -z'.
8689 2006-10-04 Paul Eggert <eggert@cs.ucla.edu>
8691 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE):
8692 Use a single call to AC_DO_TOKENS rather than multiple, for
8694 (_AC_LINK_IFELSE): Test that resulting file is executable.
8695 Problem reported by mwoehlke in
8696 <http://lists.gnu.org/archive/html/bug-coreutils/2006-10/msg00048.html>.
8698 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Use "test -x /" rather
8699 than creating a file to use with test -x; this is much faster.
8701 2006-10-02 Bruno Haible <bruno@clisp.org>
8703 * lib/autom4te.in (Automake-preselections): Add
8704 AM_GNU_GETTEXT_INTL_SUBDIR, for automake 1.10.
8706 2006-09-27 Stepan Kasal <kasal@ucw.cz>
8708 * doc/autoconf.texi (Writing testsuite.at): Fix a typo: for
8709 standard error, `experr' should be used, not `expout'.
8711 2006-09-26 Paul Eggert <eggert@cs.ucla.edu>
8713 * lib/autoconf/functions.m4 (AC_FUNC_FSEEKO): Don't compile the

8715 * lib/autoconf/specific.m4 (_AC_SYS_LARGEFILE_MACRO_VALUE):
8716 Set cache var to 'unknown' (not 'no') if leaving the macro unset
8717 still doesn't let the program compile.
8718 (AC_SYS_LARGEFILE): Test for _LARGE_FILES only if earlier tests
8721 * lib/autoconf/functions.m4: Fix problems reported by Ralf Wildenhues.
8722 (AC_FUNC_ERROR_AT_LINE): Don't bother to check for error.h. Just
8723 include it, without including anything else.
8724 (AC_FUNC_FSEEKO): Avoid gcc -Wall warnings about constant
8726 (AC_FUNC_STRNLEN): Require AC_USE_SYSTEM_EXTENSIONS.

8731 `error.h', and include it, for a `error_at_line' prototype.
8732 Use a nonempty format string in the link test.
8733 * lib/autoconf/functions.m4 (AC_FUNC_WAIT3): Include <sys/wait.h>,

8740 can apply to constants too, and that it checks for macro defns.
8741 * lib/autoconf/general.m4 (AC_CHECK_DECL): Assume C89 or better,

8743 values. Problem reported by Ralf Wildenhues.

8905 except the first two arguments are reversed.
8906 * doc/autoconf.texi (Caching Results): New macro AC_CACHE_CHECK_INT.

8957 didn't work if some values were cached but not others. Test for
8958 broken lex libraries like native ia64-hp-hpux11.22; see
8959 <http://sources.redhat.com/ml/binutils/2003-12/msg00337.html>, and
8960 work around the problem by preferring an empty LEXLIB to -lfl or

9191 * tests/torture.at (Configuring subdirectories): Set CONFIG_SITE
9192 more globally, since the 2006-06-30 patch didn't suffice. Problem
9193 reported by Keith Marshall. Also, don't bother with builddir2,
9194 since it shouldn't be needed any more.
9196 2006-07-07 Paolo Bonzini <bonzini@gnu.org>

9215 2006-07-02 Paul Eggert <eggert@cs.ucla.edu>
9217 * lib/autoconf/types.m4 (AC_TYPE_LONG_LONG_INT):
9218 Require that long long int be at least 64 bits wide. C99 requires
9219 this and enough programs depend on it so we should check for it.
9220 Bruno Haible reports in
9221 <http://lists.gnu.org/archive/html/bug-gnulib/2006-06/msg00286.html>

9233 2006-06-28 Paul Eggert <eggert@cs.ucla.edu>
9235 * doc/autoconf.texi: Be more consistent about using @acronym with
9236 "HP" and "HP-UX". Remove mention of OSF; the old version wasn't
9237 quite right (it talked about "OSF/Tru64", even though the
9238 operating systems were called OSF/1, Digital UNIX, and Tru64 UNIX,
9239 and it even mentioned "OSF 4"!) and at this point there's little
9240 reason to talk about OSF any more, since it died in 1994.
9241 (Specific Compiler Characteristics): Simplify example of
9242 negative-size array.
9243 (File Descriptors): Reorder to make the text flow better.
9244 Remove joke about "appreciate the various levels"; I didn't get it.

9248 Tone down the advice against renaming or removing open files.
9249 (Limitations of Usual Tools): Add a new section, on 'rm'.
9251 2006-06-26 Stepan Kasal <kasal@ucw.cz>
9253 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Use -lX11, not
9254 -lXt in LIBS, idea from Karsten Hopp; this was due since
9257 2005-09-18 Paul Eggert <eggert@cs.ucla.edu>
9258 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Look for X11/Xlib.h
9259 and XrmInitialize rather than X11/Intrinsic.h and XtMalloc
9260 (which belong to Xt, not X itself). See Debian bug 327655.

9306 * NEWS: Use "M4" rather than "m4" when appropriate.
9307 Problem reported by Eric Blake.
9308 * doc/autoconf.texi: Likewise.
9309 Use @acronym around BSD, GCC, and GNU when appropriate.
9310 (Why GNU M4): Renamed from "Why GNU m4".
9311 (Redefined M4 Macros): Mention that Posix
9312 m4wrap takes only 1 argument, but GNU M4 1.4.x takes more.
9313 (Buffer Overruns): Mention size_t and ptrdiff_t as alternatives
9316 2006-06-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9318 * bin/autom4te.in (handle_output): Do not forbid the empty
9320 * tests/tools.at (autoconf: the empty token): New test.
9322 2006-06-20 Stepan Kasal <kasal@ucw.cz>
9324 * lib/m4sugar/m4sugar.m4 (m4_init): Merge the two m4_wrap
9325 calls, so that we do not care whether they are LIFO or FIFO;
9326 in the m4_wrap, do not check which diversion is the topmost
9327 one, just check that the stack is balanced at the end.
9328 * lib/m4sugar/m4sh.m4 (AS_INIT): We are going to change the
9329 base diversion forever--pop the previous diversion before
9330 opening the new one; consequently, remove the m4_wrap call.
9331 * lib/autotest/general.m4 (AT_INIT): Likewise.
9332 * tests/m4sugar.at: Do not use
9333 m4_wrap([m4_diversion_pop([..])]), for educational purposes.
9335 2006-06-19 Paul Eggert <eggert@cs.ucla.edu>
9336 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9338 * NEWS: Document that m4wrap/m4_wrap might not be LIFO.
9339 * doc/autoconf.texi (Redefined M4 Macros): Likewise.
9340 Rework example of m4wrap token-pasting trouble so that it doesn't
9341 care whether it's LIFO or FIFO.
9342 Fix some "contrary to"s that are awkward in English.
9344 2006-06-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9346 * lib/autoconf/types.m4 (_AC_TYPE_INT): Set `$ac_cv_c_int$1_t'
9347 to `yes' instead of `int$1_t' if the type is found, for more
9348 consistent configure output (where $1 is the number of bits).
9349 (_AC_TYPE_UINT): Likewise for `uint$1_t'.
9350 Suggested by Bruno Haible.
9352 * lib/autoconf/types.m4 (_AC_TYPE_UNSIGNED_INT): Solaris 2.5.1
9353 needs _UINT8_T and _UINT64_T defines as well, to avoid clashes
9354 with system headers. Report by Bruno Haible.
9356 2006-06-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9358 * config/config.guess, config/config.sub: Sync from upstream.
9360 * bin/Makefile.am (autoconf.in): Use `--melt' for autom4te,
9361 in order to avoid picking up an older installed frozen m4sh.m4f.
9362 Besides an outdated shell startup, this could have been created
9363 by an earlier M4 version with incompatible frozen file format.
9365 2006-06-16 Paul Eggert <eggert@cs.ucla.edu>
9367 * README: Recommend m4 1.4.4 instead of 1.4.3..
9368 * doc/autoconf.texi: Likewise.
9369 (Special Chars in Names): Say that $(.FOO) is portable, as
9370 suggested by Stepan Kasal.
9371 (Installation Directory Variables, Build Directories):
9372 (Automatic Remaking, Subdirectories, Fortran Compiler):
9373 (Making testsuite Scripts, Defining Directories):
9374 Quote variable usages better.
9375 (Making testsuite Scripts): Add clean-local rule to makefile
9376 snippet, by Eric Blake.
9377 (Installation Directory Variables): Fix table item font.
9378 Reword slightly to clarify. Generalize advice about
9379 not using special characters to include all file-related
9380 vars, not just VPATH.
9381 (Special Chars in Variables): Warn about special characters in
9383 (Assignments): Clarify default-value example as suggested by
9385 <http://lists.gnu.org/archive/html/autoconf-patches/2006-06/msg00072.html>.
9386 (Special Shell Variables): Note leading ./ or ../, as suggested
9388 (Limitations of Builtins): Under cd, warn about CDPATH.
9389 (The Make Macro MAKEFLAGS): Untabify. Problem reported by
9392 2006-06-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9394 * doc/autoconf.texi (Configuration Actions): Remove duplicate
9395 `@var', for texi2html.
9396 (Systemology): Some more word wrapping, for DVI output.
9397 (autom4te Invocation): The short option for `--melt' is `-M',
9400 2006-06-15 Paul Eggert <eggert@cs.ucla.edu>
9402 * doc/autoconf.texi: More formatting and English tweaks,
9403 many suggested by Ralf Wildenhues.
9404 Reword to avoid "@code{...}'s" and the like, since it's ugly
9405 with Emacs info mode. discontents -> woes.
9406 Put a few "will"s back. time stamp -> timestamp.
9407 side-effect -> side effect.
9409 2006-06-14 Paul Eggert <eggert@cs.ucla.edu>
9411 * doc/autoconf.texi (Initializing configure, Shell Substitutions):
9412 Warn about $@ not persisting. Problem reported by Julien Danjou in
9413 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=372179>.
9414 (Special Chars in Names): Renamed from Leading _ in Macro Names.
9415 Mention other special chars, too.
9417 2006-06-14 Eric Blake <ebb9@byu.net>
9419 * doc/autoconf.texi (The Make Macro MAKEFLAGS): New node.
9421 2006-06-13 Paul Eggert <eggert@cs.ucla.edu>
9423 * doc/autoconf.texi: Some systematic minor improvements, as
9424 follows. Use "makefile" when talking about makefiles
9425 generally (which might be named "makefile" or "Makefile" or even
9426 "foo.mk"), "Makefile" when talking about a specific makefile
9427 called "Makefile". This unclutters the text from weird quotes
9428 (e.g., "`Makefile's" in info mode). Similarly, use "@var{foo}
9429 values" rather than "@var{foo}s" and similar constructs containing
9430 "}s". Use "Make rules" rather than "Makefile rules". Minor
9431 English-language improvements. Change the prefix "sub-" to "sub"
9433 Put blank lines around examples more consistently.
9434 Avoid "rather" and "very" as intensifiers.
9435 Avoid "will" as an auxiliary.
9436 (Limitations of Make): Split this node into....
9437 (Portable Make, $< in Ordinary Make Rules, Failure in Make Rules):
9438 (Leading _ in Macro Names, Backslash-Newline-Newline):
9439 (Backslash-Newline Comments, Long Lines in Makefiles):
9440 (Macros and Submakes, The Make Macro SHELL, Comments in Make Rules):
9441 (obj/ and Make, make -k Status, VPATH and Make):
9442 (VPATH and Double-colon, $< in Explicit Rules):
9443 (Automatic Rule Rewriting, OSF/Tru64 Directory Magic):
9444 (Make Target Lookup, Single Suffix Rules, Timestamps and Make):
9445 New nodes, resulting from splitup of Limitations of Make.
9446 All cross-references changed. Raise the top node from
9447 a section to a chapter, and all subnodes accordingly.
9448 Redo the introductory wording to match the new organization.
9449 (Installation Directory Variables): Use an example that is
9450 closer to what Autoconf actually does. Mention that VPATH's
9451 value should not contain metacharacters or white space.
9452 (Fortran Compiler): Fix a VPATH bug in an example.
9453 (Leading _ in Macro Names): Mention that this problem is no longer
9454 of practical concern.
9455 (VPATH and Make): Reword the advice to make it clearer
9456 that Autoconf and Automake support VPATH in non-GNU make, but
9457 many packages have bugs in this area.
9458 ($< in Explicit Rules): Refer to Build Directories rather
9459 than using a (non-VPATH-safe) example.
9460 (Automatic Rule Rewriting): Mention the sort of disaster that
9461 can ensue with Solaris-style rule rewriting with VPATH.
9463 2006-06-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9465 * doc/install.texi (Compilers and Options): Weaken the
9466 suggestion to use GNU make for VPATH builds.
9468 * lib/autom4te.in (Automake-preselections): Add AM_PROG_CXX_C_O,
9469 AM_PROG_F77_C_O, AM_PROG_FC_C_O, AC_FC_SRCEXT, AC_FC_FREEFORM.
9471 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Fix M4 quotation
9472 in regular expression.
9474 2006-06-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9476 * doc/autoconf.texi (Installation Directory Variables):
9477 Drop extra @samp from `@table @samp' item.
9478 (Limitations of Usual Tools): Comment fix.
9479 Do not nest @samp just to point to other table items.
9480 (Writing testsuite.at) <AT_CHECK>: The second argument to
9481 `@dvar' is already @samp'ed.
9482 (Making testsuite Scripts) <AC_CONFIG_TESTDIR>: Likewise,
9483 do not use @var in the second argument.
9485 2006-06-07 Paul Eggert <eggert@cs.ucla.edu>
9487 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Look for
9488 $as_shell.exe too. Problem reported by Andreas Buening in
9489 <http://lists.gnu.org/archive/html/autoconf/2006-06/msg00038.html>.
9491 2006-06-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9493 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA): Work around
9494 `unused variable' compiler warning, for `-Wall -Werror'.
9495 Reported by Jaap Haitsma in
9496 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00012.html>.
9498 2006-06-06 Paul Eggert <eggert@cs.ucla.edu>
9500 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Remove core file, in
9501 case the compiler dumps core. Problem reported for
9502 OpenServer 5.0.7 by Tim Rice in
9503 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00019.html>.

9507 2006-06-06 Tim Rice <tim@multitalents.net>.
9509 * lib/freeze.mk: Quiet check-forbidden-patterns so the string
9510 "ERROR" only shows up in "make check" output if there is an
9513 2006-06-06 Eric Blake <ebb9@byu.net>
9515 * tests/tools.at (automatically allowed tokens): Fix typo.
9517 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
9519 * NEWS: Don't blame non-GNU VPATH compatibility issues on Automake.
9521 * doc/autoconf.texi (Integer Overflow): Mention that INT_MIN % -1
9522 typically overflows on x86 CPUs, even though the C standard

9534 * config/texinfo.tex: Sync from upstream.
9536 * bin/autoreconf.in: Trace `LT_CONFIG_LTDL_DIR'; if it has been
9537 seen, invoke libtoolize with `--ltdl' argument.
9538 * lib/autom4te.in (Autoreconf-preselections): Adjust.
9540 Suggested by Eric Blake.
9542 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
9544 * NEWS: Whoops! AC_FUNC_STRNLEN isn't obsolescent. Problem

9554 * doc/autoconf.texi: Modernize some of the references to Solaris.
9556 2006-06-05 Stepan Kasal <kasal@ucw.cz>
9558 * lib/m4sugar/m4sugar.m4 (m4_require): Modify the error
9559 message issued by AC_REQUIRE.
9560 * tests/m4sugar.at: Check m4_require's error message.
9561 * tests/base.at: Check AC_REQUIRE's error message.
9562 * tests/local.at (AT_CHECK_M4): New macro, almost identical
9564 (AT_CHECK_AUTOM4TE): ... which is now a thin wrapper around
9566 (AT_CHECK_AUTOCONF): Use AT_CHECK_M4; no longer support
9567 `expout' as the last parameter.
9568 * tests/tools.at: Adapt to the above change.
9570 2006-06-04 Stepan Kasal <kasal@ucw.cz>
9572 * doc/autoconf.texi (Limitations of Usual Tools): Correct
9573 information about race-free implementations of mkdir.
9575 2006-06-04 Eric Blake <ebb9@byu.net>

9582 2006-06-04 Paul Eggert <eggert@cs.ucla.edu>
9584 * NEWS: GNU make now recommended for VPATH builds.
9585 Mention that some macros are now documented to be obsolescent.
9586 * doc/autoconf.texi:
9587 Prefer "current" to "modern" to describe
9588 currently-used (albeit perhaps old-fashioned) hosts.
9589 Mention which ancient features no longer need to be worried about.
9590 setgid -> set-group-ID
9591 setuid -> set-user-ID (these are the Posix terms)
9592 Fix some misuses of "only".
9593 (AC_C_BACKSLASH_A, AC_C_CONST, AC_C_PROTOTYPES):
9594 (AC_C_STRINGIZE, AC_C_VOLATILE, AC_FUNC_CLOSEDIR_VOID):
9595 (AC_FUNC_GETPGRP, AC_FUNC_LSTAT, AC_FUNC_MEMCMP):

9602 Mention that these macros are obsolescent.
9603 (Installation Directory Variables): shall -> should
9604 (File Descriptors): Mention that 0, 1, 2 might get reopened.
9605 Mention that it's now safe to use 3 and 4.
9606 (Limitations of Usual Tools): cp -r is now specified by Posix.
9607 Omit longwinded and obsolescent discussion of cp -f.
9608 Modernize discussion of expr, ls.
9609 (Limitations of Make): Modernize discussion of VPATH builds.
9610 Mention $? as a workaround in some cases.
9611 * doc/install.texi (Basic Installation):
9612 Mention "./configure; make; make install" first. Be more
9613 specific about why this file is generic. Remove unnecessary
9614 parens. Remove misleading "only". Remove obsolete advice
9615 about csh. Don't say "configure" takes awhile; say it
9616 might take a while. Suggest CFLAGS=-g rather than CFLAGS=-O2,
9617 and CC=c99 rather than CC=c89, as these are blessed by current
9618 Posix. Recommend GNU make if doing a VPATH build.
9620 2006-06-03 Paul Eggert <eggert@cs.ucla.edu>
9622 * doc/autoconf.texi: Use a consistent style "$ @kbd{...}" for
9623 examples involving shell prompts.

9626 and Paul Eggert <eggert@cs.ucla.edu>
9628 * doc/autoconf.texi (Here-Documents): Add details about the
9629 pre-ksh93g bug. Reword slightly to make it clearer. Consistently
9630 use "here-documents" instead of "here documents".
9632 2006-06-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

9638 * doc/autoconf.texi (File System Conventions): Warn about ":"
9639 anywhere in directory names.
9641 2006-05-31 Paul Eggert <eggert@cs.ucla.edu>
9643 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be even more conservative
9644 about quoting the case statement, just in case.
9645 * doc/autoconf.texi (Here-Documents): Mention that the ksh bug
9646 was fixed in ksh93g; reported by Ralf Wildenhues.
9648 2006-05-31 Stepan Kasal <kasal@ucw.cz>
9650 * doc/autoconf.texi (System Services): Do not document

9660 argument with leading hyphen. Problem reported by Paul Eggert.
9662 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
9664 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be more conservative
9665 about quoting ac_try: quote all of it, if any of it seems suspicious.
9666 This means we don't have to worry about ${ or sed any more.
9667 Also, double-quote the case statement, to work around misuses via
9668 underquoting as reported by Ralf Wildenhues in
9669 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00169.html>.
9670 (_AC_EVAL_STDERR): Revert, since evidently some packages rely on this
9671 undocumented and dangerous macro.

9681 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
9683 * lib/autoconf/general.m4: Revert AC_TRY_EVAL and AC_TRY_COMMAND,
9684 since evidently some packages rely on the old, broken behavior.
9685 Problem reported by Ralf Wildenhues in
9686 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00160.html>.
9687 (AC_TRY_EVAL, AC_TRY_COMMAND, _AC_EVAL): Go back to the
9688 pre-2006-05-26 definitions, but leave in the comments that
9689 these macros are dangerous and should not be used.
9690 (_AC_DO_ECHO): Renamed from _AC_EVAL_ECHO. All callers changed.
9691 (_AC_DO): Renamed from _AC_EVAL. All callers changed.
9692 (_AC_DO_STDERR): Renamed from _AC_EVAL_STDERR. All callers changed.
9693 (_AC_DO_VAR): Renamed from AC_TRY_EVAL.
9694 (_AC_DO_TOKENS): Renamed from AC_TRY_COMMAND.
9696 2006-05-29 Paul Eggert <eggert@cs.ucla.edu>
9698 * lib/autoconf/status.m4 (AC_OUTPUT_MAKE_DEFS): Rewrite to avoid
9699 the use of 'tr', since this is our only use of 'tr'.
9701 2006-05-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9702 and Paul Eggert <eggert@cs.ucla.edu>
9704 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE):
9705 Don't assume 'grep' works on long lines, since AIX grep doesn't.
9707 2005-05-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9709 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Do not use `grep' on
9710 the output file in the `${datarootdir}' test.
9712 2005-05-28 Stepan Kasal <kasal@ucw.cz>
9713 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9715 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If we have not seen
9716 mention of `datarootdir' in the input file(s), but literal
9717 `${datarootdir}' in the output file, and we haven't warned yet,
9718 then warn as well: the user may have (erroneously) used
9719 `AC_SUBST([mydatadir], [$datadir/my])' instead of the correct
9720 `AC_SUBST([mydatadir], ['${datadir}/my'])'.
9721 * tests/torture.at (datarootdir workaround): Extend this test.
9724 2006-05-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9725 and Paul Eggert <eggert@cs.ucla.edu>
9727 * doc/autoconf.texi (autoheader Invocation): The first argument to
9728 `AC_DEFINE_UNQUOTED' need not be a literal. Mention the
9729 alternatives and clear up the language a bit.
9731 2006-05-27 Paul Eggert <eggert@cs.ucla.edu>
9733 * NEWS: Reword notice for AC_TRY_COMMAND, AC_TRY_EVAL,
9734 ac_config_guess, ac_config_sub, ac_configure.
9735 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
9736 Fix typo that prevented an unnecessary space from being removed.
9737 Problems reported by Ralf Wildenhues in:
9738 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00143.html
9740 2006-05-26 Paul Eggert <eggert@cs.ucla.edu>
9742 * doc/autoconf.texi (Particular Programs, Limitations of Usual Tools):
9743 Use better wording to talk about AC_PROG_MKDIR_P's thread-safety.
9744 Don't use the term "thread-safe" to talk about mkdir race
9745 conditions, since the problem is more a process than a thread
9746 issue. Problem reported by Stepan Kasal in:
9747 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00088.html
9748 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Use code that mimics
9749 the test for 'install' more closely. Look at MKDIR_P first.
9750 Look in the PATH, and at /opt/sfw/bin.
9751 Look for a 'gmkdir' program as well (Solaris 10 /opt/sfw/bin/gmkdir).
9752 Don't bother to try mkdir -p, since we already check mkdir --version;
9753 just look at the version number. (There's no easy way to check
9754 for race-free implementations.)
9755 * tests/tools.at (autoconf: subdirectories): Adjust to above
9756 changes, since MKDIR_P now might end in "/mkdir -p".
9758 * doc/autoconf.texi (autoheader Invocation): Mention that the
9759 first arg of AC_DEFINE_UNQUOTED must be a literal.
9760 Problem reported by Ben Pfaff in
9761 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00090.html>.
9763 * NEWS: Mention that AC_TRY_COMMAND and AC_TRY_EVAL may be removed.
9764 * doc/autoconf.texi (Special Chars in Variables): New section.
9765 (Preset Output Variables): Warn about special chars in CPPFLAGS.
9766 (Installation Directory Variables): Quote $(datadir) better.
9767 (Limitations of Builtins): Describe some of eval's trickiness.
9769 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Simplify quoting.
9770 * lib/autoconf/fortram.m4 (_AC_PROG_FC_V_OUTPUT): Likewise.
9771 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Put leading space
9772 in front of every arg, not just trailing args. Quote apostrophes.
9773 (_AC_EVAL_ECHO): New macro.
9774 (_AC_EVAL, AC_EVAL_STDERR): Use it. Quote arg of eval.
9775 (AC_TRY_EVAL, AC_TRY_COMMAND): Mention that these macros might get
9777 (_AC_LINK_IFELSE): Use proper rule for shell continuation lines,
9778 exposed by quoting of eval argument. Put the command on line line
9780 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): Use eval more safely.
9781 (_AC_PATH_X, AC_PATH_X): Quote more safely.
9782 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Use eval more safely.
9783 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Don't use eval.
9784 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Minor style change.
9785 Handle special chars in prefix, ac_srcdir, ac_aux_dir.
9786 Use eval more safely.
9787 (_AC_OUTPUT_CONFIG_STATUS): Adjust to above changes.
9788 * lib/m4sugar/m4sh.m4 (AS_VAR_GET): Note that this API needs

9791 lines, exposed by quoting of eval argument.
9793 2006-05-26 Stepan Kasal <kasal@ucw.cz>
9794 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9796 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Drop the
9797 initialization of `ac_cv_exeext', do not override it if it was
9798 already set, unless it was set to `no', for compatibility with
9799 Autoconf-2.13, and comment this.
9800 Do not export `ac_cv_exeext', Libtool hasn't needed this for years.
9801 (_AC_COMPILER_EXEEXT_DEFAULT): Likewise, do not export it.
9802 (_AC_COMPILER_EXEEXT_WORKS, _AC_COMPILER_EXEEXT_CROSS): Typos.
9803 * doc/autoconf.texi (Compilers and Preprocessors) <EXEEXT>:
9804 Document that this test may be overridden by setting
9807 2006-05-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9809 Revert these two patches:
9811 2006-04-06 Eric Blake <ebb9@byu.net>
9812 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_O): Inside cache
9813 check, s/ac_exeext/ac_cv_exeext/. Fixes regression introduced
9816 2006-04-01 Stepan Kasal <kasal@ucw.cz>
9817 Clean up _AC_COMPILER_EXEEXT* macros.
9818 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't try to
9819 detect exeext, it will be done by _AC_COMPILER_EXEEXT_O; just set
9820 ac_file to the name of the default output file and call
9821 _AC_COMPILER_EXEEXT_WORKS. Move the definition of ac_files and the
9822 initial `rm' of the candidate files...
9823 (_AC_COMPILER_EXEEXT): ... here and simplify them. Moreover, use
9824 the same list in subsequent `rm' calls, and for the temporary
9825 redefinition of ac_clean_files; call _AC_COMPILER_OBJEXT at the end,
9826 and don't call the other _AC_COMPILER_EXEEXT_* macros directly, use...
9827 (_AC_COMPILER_EXEEXT_TESTS): ... this new macro.
9828 (_AC_COMPILER_EXEEXT_O): Don't export ac_cv_exeext, it's not needed (or
9829 no longer needed) by libtool. Make it a cache check.
9830 (_AC_COMPILER_EXEEXT_CROSS): Remove the comment, it was obviously
9831 copied here by mistake.
9832 (AC_NO_EXECUTABLES): Redefine _AC_COMPILER_EXEEXT_TESTS, not
9833 _AC_COMPILER_EXEEXT.
9834 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX, AC_PROG_OBJC): Do not call
9835 _AC_COMPILER_OBJEXT directly.
9836 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
9838 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9840 * doc/autoconf.texi (Limitations of Usual Tools) < sed (`t')>:
9841 Fix description of how the buggy `sed' works.
9843 2006-05-25 Noah Misch <noah@cs.caltech.edu>
9847 * lib/Autom4te/XFile.pm (lock): Allow EOPNOTSUPP, besides
9848 ENOLCK. Only mention `make -j' when applicable. Only raise
9849 fatal errors when `make -j' is involved. Improve error message.
9851 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9853 * doc/autoconf.texi (Here-Documents): We now know more about
9854 the variable expansion in here documents bug.
9855 Thanks to Tim Rice and Stepan Kasal.
9857 * doc/autoconf.texi (Making testsuite Scripts): Add an example
9858 how to use TESTSUITEFLAGS. Suggested by Eric Blake.
9860 2006-05-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9862 * tests/autotest.at (Multiline command from M4 expansion):
9863 No failure to be expected if the shell quotes newlines in
9864 commands in the `set -x' output. Report by Tim Rice.
9867 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
9869 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Don't use shell
9870 expansion in the here-documents used by config.status, as that
9871 runs afoul of the Korn shell version M-12/28/93d bug described in
9872 the Autoconf manual, and this in turn causes a Coreutils 5.95 build to
9873 fail as described by Tim Rice and diagnosed by Ralf Wildenhues in
9874 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00082.html>.
9876 2006-05-23 Jim Meyering <jim@meyering.net>
9878 * lib/autoconf/functions.m4 (AC_FUNC_LSTAT_FOLLOWS_SLASHED_SYMLINK):
9879 Fix typo introduced with 2006-04-02 change. It reversed the sense
9882 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
9884 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Simplify ac_dA and
9885 ac_dB slightly, to save bytes in the script.
9886 Max out at 50 lines, rather than 96; this is more likely
9887 (though not guaranteed) to avoid obscure 'sed' failures.
9889 2006-05-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9891 * lib/autotest/general.m4 (AT_INIT): UnixWare `tr' may interpret
9892 `tr -d -' as bad option argument. Work around this by deleting
9893 an unrelated character.
9894 Report by Tim Rice <tim@multitalents.net>.
9896 2006-05-22 Paul Eggert <eggert@cs.ucla.edu>,
9897 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
9898 Stepan Kasal <kasal@ucw.cz>
9900 * doc/autoconf.texi (Particular Programs): Do not promise that
9901 we always prefer the GNU version of the program, and that we
9902 search according to PATH; both rules can have exceptions.
9903 Update description of AC_PROG_GREP, AC_PROG_EGREP, AC_PROG_FGREP,
9904 AC_PROG_SED. Move descriptions of limitations
9905 to the Limitations of Usual Tools section.
9906 (Limitations of Usual Tools) <sed>: Mention script length
9907 limitations with Solaris /usr/ucb/sed.
9908 <grep>: Fix wording for empty alternative. Mention that -c and
9909 -l should not be combined, and that -E and -F should not be
9912 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
9913 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9915 * lib/autoconf/programs.m4 (AC_PROG_SED): Catch script length
9916 limits in Solaris 8 /usr/ucb/sed by testing a long script.
9918 2006-05-22 Stepan Kasal <kasal@ucw.cz>
9920 * doc/autoconf.texi (Defining Symbols): Literal parameter of
9921 AC_DEFINE is now passed to m4_pattern_allow.
9922 * NEWS: Mention that; likewise for AC_SUBST.
9923 * lib/autoconf/general.m4 (AC_DEFINE_TRACE_LITERAL): Pass
9924 the parameter to m4_pattern_allow.
9925 * tests/tools.at: Add a check for that.
9927 2006-05-22 Stepan Kasal <kasal@ucw.cz>
9929 * lib/autoconf/status.m4: Fix typos.
9931 2006-05-21 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9933 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Remove
9934 only the files that this macro generates.
9936 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
9938 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: For
9939 the HP-UX sed limitation of 99 commands, labels do not count.
9940 * lib/autoconf/status.m4 (_AC_SED_CMD_LIMIT): Mention that
9942 (_AC_OUTPUT_HEADER): Revert the change from 2006-05-19.
9944 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
9946 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT):
9947 Import the following fix from coreutils:
9949 2006-01-13 Jim Meyering <jim@meyering.net>
9951 Invoke AC_CHECK_FUNCS(getmntent) unconditionally so that tests of
9952 $ac_cv_func_getmntent (e.g., in gl_LIST_MOUNTED_FILE_SYSTEMS) need
9953 not double-quote uses of that variable, to accommodate the rare
9954 case in which getmntent is available in none of the libraries
9955 checked. This happens at least on FreeBSD 5.0.
9957 2006-05-20 Paul Eggert <eggert@cs.ucla.edu>
9959 * lib/autoconf/general.m4 (AC_CONFIG_AUX_DIRS): Bring back
9960 ac_config_guess, ac_config_sub, and ac_configure, since evidently
9961 some other programs unwisely rely on these undocumented vars.
9962 But put in warning comments about them.
9963 Problem reported by Ralf Wildenhues in
9964 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00068.html>.
9965 * NEWS: Document that these variables are intended to go away.
9967 2006-05-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9969 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): Require AC_PROG_CXX,
9970 and set the language to C++ (analogous to the equivalent Fortran
9973 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): New macro.
9974 * doc/autoconf.texi (C++ Compiler): Document it.
9975 * lib/autoconf/fortran.m4 (_AC_PROG_FC_C_O): Adjust comment.
9978 2006-05-19 Paul Eggert <eggert@cs.ucla.edu>
9980 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Fix off-by-one bug
9981 that caused config.status to generate 100-command sed scripts; the
9982 portable limit is 99.
9984 2006-05-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9986 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Name temporary
9987 variable `ac_d' instead of `d' to avoid infringing namespace.
9988 Report by Ralf Menzel.
9990 2006-05-18 Paul Eggert <eggert@cs.ucla.edu>
9992 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Don't prepend
9993 $ac_top_build_prefix to $MKDIR_P if it's just 'mkdir -p'.
9994 * tests/tools.at (autoconf: subdirectories): New test, taken from
9995 the corresponding problem report by Ralf Wildenhues in:
9996 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00053.html
9998 * lib/autoconf/functions.m4 (AC_REPLACE_FNMATCH, AC_FUNC_FNMATCH_GNU):
9999 Quote some uses of shell variables if they might suffer unexpected
10000 globbing. This doesn't fix all instances of quoting problems that
10001 I found, just the easy ones that look safe.
10002 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR, _AC_INIT_HELP):
10003 (AC_CONFIG_AUX_DIR, AC_CONFIG_AUX_DIR_DEFAULT, AC_CONFIG_AUX_DIRS):
10004 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST, AC_CANONICAL_TARGET):
10005 (AC_CACHE_LOAD, AC_CACHE_SAVE): Likewise.
10006 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF, _AC_PATH_X_DIRECT): Likewise.
10007 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Likewise.
10008 * lib/autoconf/status.m4 (_AC_OUTPUT_LINK, _AC_OUTPUT_SUBDIRS):
10010 * lib/autotest/general.m4 (_AC_INIT_PARSE_ARGS): Likewise.
10011 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Likewise.
10013 2006-05-18 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10015 * bin/autoreconf.in ($help): Reword according to the manual.
10016 Suggested by Olly Betts.
10018 2006-05-17 Olly Betts <olly@survex.com> (tiny change)
10019 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10021 * bin/autoreconf.in: Pass the directory argument to
10022 `require_configure_ac'. Fix comment.
10023 * tests/torture.at (Configuring subdirectories): Expose this.
10024 Reported by Olly Betts.
10026 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10028 * lib/Automake/Configure_ac.pm, lib/Automake/Channels.pm,
10029 lib/Automake/FileUtils.pm, lib/Automake/Struct.pm: Sync from
10030 Automake as follows:
10032 * lib/Autom4te/Configure_ac.pm (find_configure_ac): Use
10033 `$configure_in' instead of `configure.in', to preserve
10034 directory component.
10036 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10038 * config/config.guess, config/config.sub, config/texinfo.tex,
10039 doc/make-stds.texi, doc/standards.texi: Sync from upstream.
10041 2006-05-14 Paul Eggert <eggert@cs.ucla.edu>
10043 * lib/autoconf/headers.m4 (AC_HEADER_STDBOOL): Fix overly-picky
10044 test for C99 conformance; (bool) 0.5 is an integer constant
10045 expression, but (bool) -0.5 is not. Problem reported by Fedor
10046 Sergeev in <http://forum.sun.com/jive/thread.jspa?threadID=96202>.
10048 2006-05-13 Paul Eggert <eggert@cs.ucla.edu>
10050 * doc/autoconf.texi (Particular Programs): AC_PROG_MKDIR_P now
10051 sets MKDIR_P, not mkdir_p, to avoid collisions with Automake.
10052 Warn about obsolete install-sh files. Remove stray sentence
10053 fragment and fix cross reference.
10054 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Don't insist on
10055 install -d; this undoes the 2006-05-10 change.
10056 (MKDIR_P): Mark with AN_MAKEVAR.
10057 (AC_PROG_MKDIR_P): Fall back on $ac_install_sh, not $INSTALL, so
10058 that we don't require $INSTALL to be thread-safe. Move comments
10059 out of generated code. Require AC_CONFIG_AUX_DIR_DEFAULT instead
10060 of AC_PROG_INSTALL. Output a message saying that we're checking
10061 mkdir -p. Set MKDIR_P rather than mkdir_p. Do special magic for
10062 MKDIR_P instead of AC_SUBST.
10063 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE, _AC_OUTPUT_CONFIG_STATUS):
10064 Special magic for MKDIR_P, too.
10065 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Remove comment that defeated
10067 * tests/local.at (AT_CHECK_ENV): mkdir_p -> MKDIR_P.
10069 2006-05-11 Paul Eggert <eggert@cs.ucla.edu>
10071 Sync from Automake, as follows:
10073 2006-05-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10074 * config/install-sh: Initialize IFS, so field splitting isn't
10076 * config/mkinstalldirs: Likewise.
10077 * config/missing: Remove superfluous quotes. Replace all uses of
10078 `[' by `test', for consistency, and for..
10079 * config/missing (sed_minuso, sed_output): New variables.
10080 (autom4te, help2man, makeinfo): Use them. Unifies detection of
10081 `-o FILE', `--output FILE', `--output=FILE', stricter regex.
10082 Fixes `missing' to detect `--output' for help2man. Fixes
10083 PR automake/483. Report by Dennis J. Linse.
10084 (autom4te): Document in `missing --help'.
10086 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
10088 * NEWS: New macro AC_PROG_MKDIR_P. AS_MKDIR_P is now more robust.
10089 * config/install-sh: Don't use 'path' to talk about file names,
10090 as per GNU coding standards. Close a race condition reported by Ralf
10091 Wildenhues and Stepan Kasal. There is still a race condition
10092 on hosts that predate Posix 1003.1-1992, but we can't help this.
10093 Don't mishandle weird characters like space on pre-Posix hosts.
10094 Invoke mkdir at most once per dir arg on pre-Posix hosts.
10095 * doc/autoconf.texi (Programming in M4sh): Cross-reference to
10096 AC_PROG_MKDIR_P from AS_MKDIR_P.
10097 (Limitations of Usual Tools): Cross-reference to AC_PROG_MKDIR_P
10098 from mkdir. Mention that Autoconf 2.60 install-sh is safe but
10099 earlier editions are not (including Automake 1.8.3).
10100 Do not suggest mkinstalldirs for thread-safety.
10101 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Insist on an 'install'
10102 that understands -d, so that AC_PROG_MKDIR_P can fall back on $INSTALL.
10103 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Make it more robust in the
10104 presence of special characters and race conditions.
10105 * tests/local.at (AT_CHECK_ENV): Add mkdir_p to the list of variables
10106 in Autoconf's name space.
10108 2006-05-10 Bruno Haible <bruno@clisp.org>
10109 and Paul Eggert <eggert@cs.ucla.edu>
10111 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): New macro, taken
10112 from Automake with minor changes.
10113 * doc/autoconf.texi (Particular Programs): Document AC_PROG_MKDIR_P.
10115 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
10117 * config/install-sh: Update to Automake CVS version, as follows:
10118 2006-04-25 Stepan Kasal <kasal@ucw.cz>
10119 * lib/install-sh: Simplify the expr implementation of dirname.
10120 2006-04-24 Paul Eggert <eggert@cs.ucla.edu>
10121 * lib/install-sh: Handle --, and diagnose unknown options.
10123 2006-05-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10125 * tests/Makefile.am (AUTOTEST): Use `$(MY_AUTOM4TE)' instead of
10126 `./autom4te' to create `./testsuite', since the `all' target
10127 will ensure its presence, but `installcheck' should not create
10128 the uninstalled wrappers.
10130 * tests/torture.at (Unusual Automake input files): Skip if we
10131 detect automake < 1.8.
10133 2006-05-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10135 * lib/autoconf/c.m4 (AC_PROG_CC_STDC): If ac_cv_prog_cc_stdc
10136 is set to `no', then that overrides and sets ac_cv_prog_cc_c89
10137 and ac_cv_prog_cc_c99 to `no', for backward compatibility.
10140 2006-05-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10142 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Take care not to
10143 munge (multiple) white space and other oddities.
10144 * tests/torture.at (AT_CHECK_AC_ARG_VAR): Make sure to M4-escape
10145 single quotes in variable assignment.
10146 (AC_ARG_VAR, configure invocation): Adjust tests to expose this
10147 and similar failures by adding multiple spaces, tabs, and other
10148 special characters.
10149 Report and different test suggested by Francesco Romani
10150 <fromani@gmail.com> and Andrew Church <achurch@achurch.org>.
10152 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): When we escape
10153 single quotes, we only need to search for single quotes; this
10154 both simplifies the search pattern, and makes us less
10155 susceptible to `echo' variations for arguments not containing
10157 (_AC_ARG_VAR_VALIDATE): Likewise.
10159 2006-05-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10161 * doc/autoconf.texi (Special Shell Variables) <IFS>: Document
10162 `$*' and IFS concatenation issue with traditional shells and
10163 bash-2.04. Report by Seanster@Seanster.com.
10165 2006-05-03 Bruno Haible <bruno@clisp.org>
10167 * doc/autoconf.texi (Limitations of Usual Tools): Identify more
10168 precisely which Mac OS X versions have the od problem.
10170 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
10172 * doc/autoconf.texi: Use @option systematically.
10174 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
10175 and Bruno Haible <bruno@clisp.org>
10177 * doc/autoconf.texi (Limitations of Usual Tools): Add a paragraph
10179 (Integer Overflow): Mention the special case of integer division
10182 2006-05-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10184 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Cater for
10185 traditional shells like the Solaris one that do not use the
10186 first IFS character for assembling `$*'.
10187 Prompted by a related report from autoconf_bug@nro.ca.
10189 2006-05-01 Paul Eggert <eggert@cs.ucla.edu>

10245 2006-04-25 Paul Eggert <eggert@cs.ucla.edu>
10247 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Don't use AS_ERROR,
10248 since as_me isn't set yet.
10250 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
10252 Prepare for deprecation of AS_BASENAME and AS_DIRNAME, and fix
10253 a few minor bugs in this area.
10255 * doc/autoconf.texi (Programming in M4sh): Comment out the
10256 documentation of AS_BASENAME, for now.
10257 (Shell Substitutions): Do not use AS_DIRNAME in an example.
10258 (Limitations of Builtins) <basename>: Do not refer to
10260 * bin/autoconf.as (me): Don't use AS_BASENAME.
10261 (dir): Remove the unused variable.
10262 * lib/m4sugar/m4sh.m4 (_AS_DETECT_REQUIRED): Renamed from
10263 AS_DETECT_REQUIRED. All uses changed.

10278 * doc/autoconf.texi (Runtime): Renamed from "Run Time". All uses
10279 of "run time" and "run-time" changed to "runtime", for consistency.

10282 * lib/autoconf/general.m4: Likewise.
10283 * lib/autoconf/headers.m4: Likewise.
10285 * doc/autoconf.texi (Run Time): Document the exit status situation
10286 with more accuracy and detail.
10288 2006-04-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10290 * doc/autoconf.texi (Introduction): The GNU Autoconf Macro
10291 Archive is not officially `GNU' any more. Update URL.
10292 (Defining Directories): Likewise
10293 * lib/autoconf/c.m4 (AC_C_RESTRICT): Update URL.
10295 2006-04-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10297 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Remove the leading
10298 newline from the `trap' code to finish `config.log'; the NetBSD
10299 /bin/sh resets the exit status after an empty command, as
10300 documented in doc/autoconf.texi.
10301 Reported by Dalibor Topic <robilad@kaffe.org>.
10303 2006-04-19 Paul Eggert <eggert@cs.ucla.edu>
10305 * doc/autoconf.texi (C Compiler): Clarify AC_C_TYPEOF.
10306 Suggested by Bruno Haible.
10308 2006-04-18 Paul Eggert <eggert@cs.ucla.edu>
10310 * configure.ac (ac_cv_sh_n_works): Don't try to test for it, since
10311 some shells (e.g., Solaris 8 /bin/sh) implement it verrrry slowly.
10312 Instead, just list the shells that we know work.
10313 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Remove 2nd arg. All uses
10314 changed. Be more cautious about the _cv_ variable.
10315 * tests/tools.at (Syntax of the shell scripts): Check the
10316 _cv_ variable once, at first, to avoid an internal autoconf error
10317 when sh -n does not work.
10319 2006-04-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10321 * lib/Autom4te/FileUtils.pm: Sync from Automake.
10323 2006-04-16 Paul Eggert <eggert@cs.ucla.edu>
10325 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Don't
10326 use ">&-" since we're only 99.999% sure that this is portable,
10327 and since the MinGW bug is fixed in a different way.
10328 * lib/autotest/general.m4 (AT_INIT): Likewise.
10330 2006-04-16 Stepan Kasal <kasal@ucw.cz>
10332 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Handle --recheck
10333 before opening config.log, to avoid hitting a bug on MinGW.
10335 2006-04-14 Paul Eggert <eggert@cs.ucla.edu>
10337 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Close
10338 AS_MESSAGE_LOG_FD before reopening it onto the log file.
10339 This works around a MinGW bug reported by Eric Paire.
10340 Make sure that all writes to the log file append to it,
10341 rather than possibly losing data.
10342 * lib/autotest/general.m4 (AT_INIT): Likewise.
10344 2006-04-14 Stepan Kasal <kasal@ucw.cz>
10346 * lib/Autom4te/FileUtils.pm (find_file): Fix a typo in the
10349 2006-04-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10353 * configure.ac (AC_INIT): Bump to 2.59d.
10355 2006-04-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10359 * Makefile.maint (news-date-check): Do not require a leading `*'
10360 before the release date in NEWS.
10362 2006-04-12 Stepan Kasal <kasal@ucw.cz>
10363 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10365 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If the templates for
10366 the instantiated file do not contain the string 'datarootdir'
10367 but contain @datadir@, @docdir@, @infodir@, @localedir@, or
10368 @mandir@, replace the reference '${datarootdir}' by the value.
10369 * tests/torture.at (datarootdir workaround): New test.
10370 * NEWS: Advertise this temporary fixup.
10371 Based on a patch by Bruno Haible, reported and analyzed by
10372 Paul Eggert and Noah Misch.
10374 2006-04-12 Eric Blake <ebb9@byu.net>
10376 * tests/autotest.at (Debugging a failed test): Fix comment.
10378 2006-04-12 Stepan Kasal <kasal@ucw.cz>
10380 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): Simplify the summary of
10381 all the changes since 2006-04-07.
10383 2006-04-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10385 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): If `ln -s file1 file2'
10386 succeeded, but `ln -s file dir' failed, take care to remove the
10387 leftover target before the next test, to prevent its spurious
10388 failure; also make sure `ln file dir' works before selecting it.
10389 Thanks to Keith Marshall for pointing this out.
10392 * lib/autotest/general.m4 (AT_INIT): Store quoted variable
10393 assignments in `at_debug_args', so that we put them correctly
10394 in the `run' script.
10395 * tests/autotest.at (Debugging a failed test): Unmark XFAIL.
10396 Reported by Eric Blake.
10398 2006-04-11 Eric Blake <ebb9@byu.net>
10400 * tests/autotest.at (AT_CHECK_AT): Add new argument, to allow
10401 top-level tests after micro-suite has been run. Used in...
10402 (Debugging a successful test, Debugging script and environment),
10403 (Debugging a failed test): ...these new tests. The first of these
10405 * lib/autotest/general.m4 (_AT_CREATE_DEBUGGING_SCRIPT): New
10406 macro, split out from...
10407 (AT_INIT): ...here, so that using -d also generates a run script.
10408 Document that -d inhibits top-level logging.
10409 * doc/autoconf.texi (testsuite Invocation): Document that -d only
10410 inhibits top-level logging; debug scripts are created.
10412 * lib/autotest/general.m4 (_AT_CHECK): Avoid syntax error on empty
10414 * tests/autotest.at (Empty test, Empty check): New test to check it.
10416 * lib/autoconf/c.m4 (AC_C_CONST, AC_C_VOLATILE): Avoid warnings
10419 2006-04-10 Stepan Kasal <kasal@ucw.cz>
10421 * tests/mktests.sh: Use "trap '' 0", not "trap 0". Do not touch
10422 the files if a problem appears. Make the empty *.at files
10423 read-only, too. Proposed by Ralf Wildenhues.
10425 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10427 * config/Makefile.am: Add comment to force updated Makefile.in.
10429 * lib/freeze.mk: Fix typo in comment. Unlike the last, white
10430 space only patch to this file, this patch causes the Makefile.in
10431 files that include freeze.mk to be updated, and thus have a
10432 newer time stamp again, which in turn makes a pristine CVS
10433 checkout have correct time stamps.
10435 * Makefile.maint (cvs-sv): New macro, to be used..
10436 (config.guess-url_prefix, config.sub-url_prefix)
10437 (texinfo.tex-url_prefix, standards.texi-url_prefix): ..here;
10438 point to CVS text checkout of Gnulib files.
10439 (copyright-check): Bump current year.
10440 (announcement): Do not hard-wire `./announce-gen'.
10441 (cvs-update): Propagate failures of `cvs' and `move-if-change'
10443 * Makefile.cfg (executable-update): Use `chmod a+x' instead of
10445 (wget_files): Update config.guess, config.sub, texinfo.tex by
10446 `wget-update', now that their URLs work again.
10448 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
10450 * doc/autoconf.texi (Particular Types): Don't use AC_CHECK_TYPE.
10451 Problem noted by Paul D. Smith.
10453 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10455 * doc/autoconf.texi: Remove unused words from word list.
10456 * .x-sc_prohibit_atoi_atof, .x-sc_space_tab, .x-sc_sun_os_names,
10457 .x-sc_trailing_space: New files.
10459 * doc/standards.texi: Sync from gnulib.
10461 * NEWS, doc/autoconf.texi (AC_LIBOBJ vs LIBOBJS): Mark
10462 `LIBOBJDIR' as experimental.
10464 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): MSYS `ln -s' fails
10465 with a target directory; it's internally implemented as `cp'
10466 anyway, but since Autoconf advertises the possibility to use
10467 a target directory when LN_S is `ln -s', we need to find out.
10468 Reported by Rolf Ebert <rolf.ebert.gcc@gmx.de> against MSYS,
10469 analyzed by Keith Marshall <keith.marshall@total.com>.
10473 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
10475 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Just output
10476 confdefs.h as-is. In general, if it has backslash-newline or the
10477 like, then it doesn't work either to sort or to remove empty
10480 2006-04-09 Stepan Kasal <kasal@ucw.cz>
10482 * tests/Makefile.am (AUTOCONF_FILES): Fix typo in the comment.
10484 2006-04-09 Alexandre Duret-Lutz <adl@gnu.org>
10486 * lib/autom4te.in (Automake-preselections): Preselect
10489 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>
10491 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Use '\'' for an
10492 apostrophe within a single-quoted string, as this is the usual
10493 tradition and is easier to read than '"'"'. Don't rely on the
10494 shell treating "$/" like '$/'. Use a more-consistent indenting
10495 style for the trap.
10497 2006-04-09 Eric Blake <ebb9@byu.net>
10499 * tests/autotest.at (Backquote command substitution),
10500 (Multiline backquote command substitution): Remove mistaken
10501 AT_NO_CMDSUBST from the 2006-03-14 patch, which was meant to be
10503 (Parenthetical command substitution, Multiline parenthetical
10504 command substitution): here.
10506 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>
10508 Import macros from gnulib (often changing their name).
10510 * NEWS: AC_C_TYPE_LONG_DOUBLE is now obsolete.
10511 New macros AC_CHECK_DECLS_ONCE, AC_CHECK_FUNCS_ONCE,

10522 (Pointers): Add Gnulib URL.
10523 (Particular Functions): Alphabetize. Add AC_FUNC_STRTOLD.
10524 (Generic Functions): Add AC_CHECK_FUNCS_ONCE. Refer to new
10526 (Particular Headers): Add AC_HEADER_ASSERT. For stdbool.h,

10530 (Generic Declarations): Add AC_CHECK_DECLS_ONCE.
10531 (Particular Structures): Add AC_STRUCT_DIRENT_D_INO,

10535 Add AC_TYPE_INT8_T, AC_TYPE_INT16_T, AC_TYPE_INT32_T, AC_TYPE_INT64_T,
10536 AC_TYPE_INTMAX_T, AC_TYPE_INTPTR_T, AC_TYPE_LONG_DOUBLE,
10537 AC_TYPE_LONG_DOUBLE_WIDER, AC_TYPE_LONG_LONG_INT, AC_TYPE_UINT8_T,
10538 AC_TYPE_UINT16_T, AC_TYPE_UINT32_T, AC_TYPE_UINT64_T,
10539 AC_TYPE_UINTMAX_T, AC_TYPE_UINTPTR_T, AC_TYPE_UNSIGNED_LONG_LONG_INT.
10540 (C Compiler): Move AC_C_LONG_DOUBLE to ...
10541 (Obsolete Macros): here. Under AC_LONG_DOUBLE, mention
10542 AC_TYPE_LONG_DOUBLE or AC_TYPE_LONG_DOUBLE_WIDER instead.
10543 (Posix Variants): Add AC_USE_SYSTEM_EXTENSIONS.
10544 (Coding Style). Don't mention m4_expand_once.
10545 * lib/autoconf/c.m4 (AC_C_LONG_DOUBLE): Implement via

10552 * lib/autoconf/headers.m4 (AC_CHECK_HEADERS_ONCE): New macro.
10553 (AC_HEADER_ASSERT): New macro.
10554 (AC_HEADER_STDBOOL): Don't assume "#error" works.
10555 Catch a bug in IBM AIX xlc compiler version 6.0.0.0.
10556 Catch a bug in an HP-UX C compiler.
10557 * lib/autoconf/specific.m4 (AC_USE_SYSTEM_EXTENSIONS): New macro.
10558 * lib/autoconf/types.m4 (AC_TYPE_INTMAX_T. AC_TYPE_UINTMAX_T):

10562 (_AC_STRUCT_DIRENT, AC_STRUCT_DIRENT_D_INO, AC_STRUCT_DIRENT_D_TYPE):
10565 * tests/mktests.sh (ac_exclude_list, au_exclude_list): Do not
10566 use /^foo|bar$/, it does not mean /^(foo|bar)$/.
10568 2006-04-08 Stepan Kasal <kasal@ucw.cz>
10570 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Fix the wording
10571 of the warning introduced by the 2001-08-28 change.
10573 2006-04-08 Stepan Kasal <kasal@ucw.cz>,
10574 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10576 * lib/autoconf/general.m4 (AC_CACHE_SAVE): All `ac_cv_env_foo'
10577 variables shall be overriden by the cache.
10578 * tests/torture.at (AC_ARG_VAR): Test also with a first value
10579 that contains braces.
10581 2006-04-07 Stepan Kasal <kasal@ucw.cz>
10583 Revert the patch from 2006-04-01 and only improve
10584 _AS_DETECT_BETTER_SHELL:
10586 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Do not optimize; do not
10587 skip nonexistent directories.
10588 (_AS_DETECT_BETTER_SHELL): The optimization is moved here--try
10589 only shell candidates which exist.
10590 (AS_UNAME): No need to give three parameters to _AS_PATH_WALK.
10591 * lib/autotest/general.m4 (AT_INIT): No need to give three

10640 whether `set' quotes correctly: redirect stderr of the tested
10641 `set', and use a subshell, for Ultrix; use `sed' instead of
10642 `grep' for zsh `set' which may write binary output; match only
10643 at the beginning of a line, to avoid false positives.
10644 In order to avoid false positives by unrelated variables with
10645 multiline content, put the dump algorithm in a subshell and
10646 unset all variables containing newlines (except some which are
10647 special to the shell). Warn about cache variables that are
10650 2006-04-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

10696 (_AC_CONFIG_REGISTER_DEST): Double quote the tags in macros _AC_LIST_TAGS
10697 and_AC_LIST_TAG_COMMANDS; fixes another regression introduced by the

10762 * tests/mktests.sh: Don't use 'cat'; just read the files directly.
10763 Prefer 'sort -u' to 'sort | uniq'. Filter data before sorting it.
10764 Use 'comm' rather than N instances of grep; this also fixes a bug
10765 whereby substrings were incorrectly matched, causing us to not
10766 generate tests for AC_F77_NAME_MANGLING and AC_FUNC_LSTAT.
10767 (exclude_list): Exclude empty macros.

10851 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't try to
10852 detect exeext, it will be done by _AC_COMPILER_EXEEXT_O; just set

10855 initial `rm' of the candidate files...
10856 (_AC_COMPILER_EXEEXT): ... here and simplify them. Moreover, use
10857 the same list in subsequent `rm' calls, and for the temporary
10858 redefinition of ac_clean_files; call _AC_COMPILER_OBJEXT at the end,
10859 and don't call the other _AC_COMPILER_EXEEXT_* macros directly, use...
10860 (_AC_COMPILER_EXEEXT_TESTS): ... this new macro.
10861 (_AC_COMPILER_EXEEXT_O): Don't export ac_cv_exeext, it's not needed (or
10862 no longer needed) by libtool. Make it a cache check.
10863 (_AC_COMPILER_EXEEXT_CROSS): Remove the comment, it was obviously
10864 copied here by mistake.

11559 CONFIG_SHELL in the environment of the configure rerun.
11560 * doc/autoconf.texi (Here-Documents, config.status Invocation):
11561 Suggest passing CONFIG_SHELL absolute, and in the environment
11562 rather than as option.

11566 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE):

11582 * lib/autoconf/programs.m4 (AC_CHECK_PROG, AC_PATH_PROG):
11583 Factor functionality to..
11584 (_AC_CHECK_PROG, _AC_PATH_PROG): these new macros, but only
11585 `AC_SUBST($1)' in the public version.
11586 (AC_CHECK_TOOL, AC_PATH_TOOL, AC_PATH_TARGET_TOOL)
11587 (AC_CHECK_TARGET_TOOL): Use internal versions for ac_ct_* and
11590 2005-11-01 Stepan Kasal <kasal@ucw.cz>
11592 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Remove the comment about 8+3

11607 conftst2.$ac_objext.
11608 * lib/autoconf/fortran.m4 (_AC_PROG_FC_C_O): Likewise.
11610 2005-10-24 Stepan Kasal <kasal@ucw.cz>
11612 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Use conftst2.o instead of
11613 conftest.o, to see whether the compiler really obeys; rm the object
11614 file before and after the test and register it with ac_clean_files.
11615 * lib/autoconf/fortran.m4 (_AC_PROG_FC_C_O): Likewise.
11617 2005-10-21 Stepan Kasal <kasal@ucw.cz>
11619 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): When determining,
11620 the delimiter CEOF$ac_eof: fix quoting of CEOF[0-9]* and modify the

11633 the latter'', in two places.
11635 2005-10-19 Paul Eggert <eggert@cs.ucla.edu>
11637 * doc/autoconf.texi (Generating Sources): AC_LANG_PROGRAMS ->
11638 AC_LANG_PROGRAM, fixing a typo. Don't give details about
11639 the inner workings of AC_LANG_FUNC_LINK_TRY.
11640 * lib/autoconf/c.m4 (AC_LANG_CALL(C)): Reformat to match
11641 AC_LANG_FUNC_LINK_TRY. This involves returning the value returned
11642 by the function rather than ignoring it.
11643 (AC_LANG_FUNC_LINK_TRY(C)): Call the function rather than simply
11644 comparing its address. Intel's interprocedural optimization was
11645 outsmarting the old heuristic. Problem reported by
11648 2005-10-19 Stepan Kasal <kasal@ucw.cz>
11650 * lib/autoconf/general.m4 (AC_SUBST): Remove an obsolete comment.

11657 2005-10-04 Stepan Kasal <kasal@ucw.cz>
11659 * lib/autotest/general.m4 (AT_INIT): Really make the subtree writable
11660 before removing it (chmod -R u+rwx); there are three instances of this.
11662 2005-10-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11663 Stepan Kasal <kasal@ucw.cz>
11665 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Balance parentheses.
11666 * lib/autotest/general.m4 (AT_INIT): If the test dir already exists,
11667 make its content writable before removing it. Remove an errorneous
11668 comment from the end, where the logs of the failed tests are copied
11669 to the main log file.
11671 2005-09-27 Stepan Kasal <kasal@ucw.cz>
11673 * tests/semantics.at (AC_C_BIGENDIAN): Pass --force to autoheader,
11674 in case the computer is too quick. Double quote the configure.ac
11677 * tests/local.at (AT_CHECK_AUTOCONF): Always pass --force to prevent
11678 problems if the testsuite were running too fast.
11680 2005-09-18 Paul Eggert <eggert@cs.ucla.edu>
11682 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Look for X11/Xlib.h
11683 and XrmInitialize rather than X11/Intrinsic.h and XtMalloc
11684 (which belong to Xt, not X itself). See Debian bug 327655.
11685 * NEWS: Mention this.
11687 2005-09-07 Stepan Kasal <kasal@ucw.cz>
11689 * lib/autoconf/c.m4 (AC_LANG_SOURCE(C)): Remove an incorrect comment.
11691 2005-09-06 Paul Eggert <eggert@cs.ucla.edu>
11693 * config/move-if-change: Don't output "$2 is unchanged";
11694 suggested by Ben Elliston. Handle weird characters correctly.
11696 2005-09-06 Stepan Kasal <kasal@ucw.cz>
11698 * lib/autoconf/libs.m4 (AC_SEARCH_LIBS): Merge the two AC_LINK_IFELSE
11699 calls, so that the final expansion of this macro is shorter.
11700 Create the conftest.$ac_ext outside the `for' loop, to speed the run.
11701 Do not use `break' in the argument to AC_LINK_IFELSE, it would skip
11702 the cleanup there. Use AS_VAR_* macros, to be more general.
11703 * tests/semantics.at (AC_SEARCH_LIBS): Check for the cleanup.
11705 * lib/autoconf/general.m4: Use AS_IF where appropriate.
11707 * lib/m4sugar/m4sh.m4 (AS_IF): Use m4_default.
11709 2005-09-01 Stepan Kasal <kasal@ucw.cz>
11711 * doc/autoconf.texi (Configuration Headers): Add an index entry
11714 2005-08-26 Pavel Roskin <proski@gnu.org>
11716 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): Use shell variable
11717 XMKMF to locate xmkmf. Make XMKMF precious. Export CC when
11720 2005-08-26 Paul Eggert <eggert@cs.ucla.edu>
11722 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE):
11723 The previous patch didn't work, so try a better one.
11725 2005-08-26 Stepan Kasal <kasal@ucw.cz>
11727 * doc/autoconf.texi (Programming in M4sh) <AS_TR_CPP>: Fix m4 quoting
11728 in the example. Reported by Bruno Haible.
11729 <AS_TR_SH>: Likewise. Also modify the example to be more convincing:
11730 "if $undefined_var;" succeeds with my shell.
11732 * lib/autoconf/general.m4 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST,
11733 AC_CANONICAL_TARGET): Define by AC_DEFUN, no need to use AC_DEFUN_ONCE;
11734 but change the m4_divert_text to m4_divert_once.
11736 2005-08-25 Paul Eggert <eggert@cs.ucla.edu>
11738 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE):
11739 Work around bug in Solaris /usr/xpg4/bin/awk.
11740 The bug is present in at least Solaris 8 through 10.
11742 2005-08-24 Stepan Kasal <kasal@ucw.cz>
11744 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Simplify; rejecting
11745 some evil values and relying on the fact that $* concatenates the
11746 parameters by the first character from IFS.
11748 2005-08-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
11749 Stepan Kasal <kasal@ucw.cz>
11751 * lib/autoconf/status.m4 (_AC_CONFIG_REGISTER_DEST): When the
11752 first header appears, define AH_HEADER.
11753 * doc/autoconf.texi (Configuration Headers): Document AH_HEADER.
11754 Update limitations about when to call AC_CONFIG_HEADERS.
11755 (Configuration Commands): Document that AC_CONFIG_COMMANDS_PRE
11756 parameter can call AC_SUBST, AC_DEFINE, or AC_CONFIG_FOOS; explain
11757 that AC_CONFIG_COMMANDS_PRE and AC_CONFIG_COMMANDS_POST are not
11758 ``Configuration Actions''; fix their index entries.
11760 * lib/autotest/general.m4 (AT_INIT): Process multiple keywords
11761 options correctly. Process N-M as M-N if M is smaller than N.
11762 Process ranges correctly so that N-N will run only N.
11763 Sort and uniquify the tests that will be run. If there is more
11764 than one test, reinsert the banners for the tests.
11765 * tests/autotest.at (Keywords): Unmark XFAIL.
11767 2005-08-23 Stepan Kasal <kasal@ucw.cz>
11769 * lib/autoconf/general.m4 (_AC_DEFINE_Q): Strip the parameter list
11770 before passing the macro name to AH_TEMPLATE.
11772 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): config.status
11773 now opens log after option processing; in particular, --version
11774 and --help do not touch config.log.
11776 * Makefile.maint: Revert the change from 2005-08-12.
11778 2005-08-22 Stepan Kasal <kasal@ucw.cz>
11780 * lib/autoconf/general.m4 (AC_ARG_ENABLE, AC_ARG_WITH): Factor out
11782 (_AC_ENABLE_IF, _AC_ENABLE_IF_ACTION): ... these new macros.

11786 * doc/autoconf.texi (Using Autotest, testsuite Scripts)
11787 (Autotest Logs, Writing testsuite.at, testsuite Invocation):
11790 * doc/autoconf.texi (Defining Symbols, Changed Results):
11791 Prepend to LIBS, not append, in examples.
11793 2005-08-16 Stepan Kasal <kasal@ucw.cz>
11795 When building in place, set srcdir="."; suggested by Tim Van Holder.
11797 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Do this; to recognize
11798 build in place, we need ac_pwd, and thus have to AC_REQUIRE ...
11799 (_AC_INIT_DIRCHECK): ... this macro and AC_DEFUN both of them.
11800 * lib/autoconf/status.m4 (_AC_SRCDIRS): Fix a comment: srcdir="."
11801 does not mean "no --srcdir option".
11803 2005-08-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11805 * tests/autoscan.at (autoscan): New file.
11806 * tests/suite.at: Use it.
11807 * tests/Makefile.am (TESTSUITE_HAND_AT): Add it.
11808 Reported against Libtool by Gideon Go <gideon.go@gmail.com>.
11810 * tests/autotest.at (Keywords): Test keywords combinations.
11812 2005-08-12 Stepan Kasal <kasal@ucw.cz>
11814 * Makefile.maint (GZIP_ENV): When checking the help text of gzip,
11815 add "2>&1"; gzip 1.2.4 prints help on stderr.
11817 2005-07-27 Stepan Kasal <kasal@ucw.cz>
11819 * lib/autotest/general.m4 (_AT_DECIDE_TRACEABLE): The symbol at_reason
11820 was pushdef'ed twice while popped only once. Push it only once.
11821 (_AT_CHECK): Cosmetic changes to the "case $at_status" command.
11823 2005-07-26 Stepan Kasal <kasal@ucw.cz>
11825 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): The message is now
11826 prefixed by mere "===", not "configure: === ".
11828 2005-07-25 Paul Eggert <eggert@cs.ucla.edu>
11830 * Makefile.maint: Update from Bison.
11832 * lib/m4sugar/m4sugar.m4 (m4_strip): Comment fix---change tab to
11833 "<tab>" in comment, so that the point is understandable.
11835 2005-07-25 Stepan Kasal <kasal@ucw.cz>
11837 Rewrite substantial part of lib/autoconf/status.m4.
11838 The main change is that CONFIG_FILES, CONFIG_HEADERS, CONFIG_LINKS,
11839 and CONFIG_COMMANDS are not processed in four separate loops.
11840 Instead, there is one main loop. This alows that the common code
11841 is expanded only once, thus config.status (and configure) is smaller.
11843 The registration mechnism in AC_CONFIG_FILES and cousins also changed;
11844 the AC_LIST_FILES and cousins macros are no longer used.
11846 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES, _AC_OUTPUT_HEADERS,
11847 _AC_OUTPUT_LINKS, _AC_OUTPUT_COMMANDS): Renamed to ...
11848 (_AC_OUTPUT_FILE, _AC_OUTPUT_HEADER, _AC_OUTPUT_LINK,
11849 _AC_OUTPUT_COMMAND): ..., respectively. These macros no longer
11850 contain the initialization, nor the for loop, nor the associated
11851 commands; all these go to ...
11852 (_AC_OUTPUT_MAIN_LOOP): ... this new macro, called from
11853 _AC_OUTPUT_CONFIG_STATUS.
11854 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST, _AC_CONFIG_SPLIT_FILE_IN):
11855 Nuked; the code was merged into _AC_OUTPUT_MAIN_LOOP.
11856 (_AC_OUTPUT_FILE): The creation of the sed script ...
11857 (AC_OUTPUT): ... and the setup of ac_vpsub goes to ...
11858 (_AC_OUTPUT_FILES_PREPARE): ... a new macro, also called from
11859 _AC_OUTPUT_MAIN_LOOP.
11860 (_AC_CONFIG_FILES, _AC_CONFIG_HEADERS, _AC_CONFIG_LINKS,
11861 _AC_CONFIG_COMMANDS): Use ...
11862 (_AC_CONFIG_FOOS): ... this new macro, which uses these ...
11863 (_AC_CONFIG_REGISTER, _AC_CONFIG_REGISTER_DEST): ... new macros.
11864 (_AC_CONFIG_FILE, _AC_CONFIG_HEADER, _AC_CONFIG_LINK,
11865 _AC_CONFIG_COMMAND, _AC_CONFIG_DEPENDENCIES): No longer needed.
11866 (_AC_CONFIG_DEPENDENCY): Update, it uses these ...
11867 (_AC_CONFIG_DEPENDENCY_DEFAULT, _AC_FILE_DEPENDENCY_TRACE_COLON):
11869 (_AC_CONFIG_UNIQUE): Update.
11870 (AC_LIST_FILES, AC_LIST_HEADERS, AC_LIST_LINKS, AC_LIST_COMMANDS):
11871 Replaced by this ...
11872 (_AC_LIST_TAGS): ... new common macro.
11873 (AC_LIST_FILE_COMMANDS, AC_LIST_HEADER_COMMANDS, AC_LIST_LINK_COMMANDS,
11874 AC_LIST_COMMAND_COMMANDS): Replaced by this ...
11875 (_AC_LIST_TAG_COMMANDS): ... new common macro.
11876 (_AC_CONFIG_COMMANDS_INIT): Moved top to the `registration' section;
11877 this didn't belong to the `config commands' section.
11878 (_AC_OUTPUT_COMMANDS_INIT): Don't initialize, m4_ifdef is our friend.
11879 (AC_CONFIG_COMMANDS_PRE, AC_OUTPUT_COMMANDS_PRE,
11880 AC_CONFIG_COMMANDS_POST): Moved to a new section, these didn't belong
11881 to the `config commands' section either.
11882 (AC_CONFIG_SUBDIRS): Don't touch diversion DEFAULTS.
11883 (_AC_LIST_SUBDIRS): Don't initialize, m4_ifdef is our friend.
11885 ... and many changes to the comments nearby.
11887 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): At the end of the day,
11888 set ac_subdirs_all='_AC_LIST_SUBDIRS'.
11889 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
11890 AC_CONFIG_COMMANDS(command:input,...) is no longer allowed.
11891 (#define header templates): The comment at the top of the generated
11892 header now includes the name(s) of the source file(s).
11894 Several unrelated small changes:
11896 * lib/autoconf/general.m4 (AC_CACHE_VAL): Be didactic, quote the first
11897 parameter to AC_DIAGNOSE.
11898 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS): Likewise.
11899 (_AC_LINK_FILES_CNT): Don't AU_DEFUN this; it causes confusing messages
11900 with autoupdate; use m4_define_default inside AU_DEFUNed AC_LINK_FILES.
11901 (AC_OUTPUT): In the compatibility code, use m4_ifvaln, to be consistent
11902 with AU::AC_OUTPUT.
11903 (AU::AC_OUTPUT): Don't double-quote $2 and $3, the compatibility code
11904 in AC_OUTPUT doesn't double-quote it either.
11905 * tests/tools.at (autoupdate): AU::AC_OUTPUT no longer double-quotes the
11908 2005-07-10 Stepan Kasal <kasal@ucw.cz>
11910 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Document which
11911 versions of Portland Group compiler produce single- and double-quoted
11912 -cmdline argument. Reported by Steven G. Johnson <stevenj@fftw.org>
11913 and Ole Holm Nielsen <Ole.H.Nielsen@fysik.dtu.dk>.
11915 2005-07-07 Paul Eggert <eggert@cs.ucla.edu>
11917 * tests/local.at (AT_CONFIG_CMP): Ignore lines like "LIBS=''" too.
11918 This is a corrected version of yesterday's patch.
11920 2005-07-07 Stepan Kasal <kasal@ucw.cz>
11922 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Report the full
11923 path, too; insert a "===" to emphasize the line.
11925 * lib/autoconf/general.m4 (AC_CANONICAL_BUILD): Rename
11926 ac_cv_build_alias to ac_build_alias.
11927 (AC_CANONICAL_HOST, AC_CANONICAL_TARGET): Simplify.
11929 On 2005-02-24, an unintentional AC_SUBST([CC]) was introduced; this
11930 change eliminates it. Problem reported by Alexandre Duret-Lutz.
11931 * lib/autoconf/general.m4 (_AC_ARG_VAR_PRECIOUS): Move the AC_SUBST ...
11932 (AC_ARG_VAR): ... here.
11933 (_AC_INIT_PREPARE): Call AC_SUBST for build_alias, host_alias and
11936 Keep a list of all precious variables and process them with one simple
11937 for loop, instead of expanding all commands, or, OTOH, complicated
11938 processing of output of "set".
11939 * lib/autoconf/general.m4 (_AC_ARG_VAR_PRECIOUS): Acumulate the
11940 variable names in new macro...
11941 (_AC_PRECIOUS_VARS): ... which will be assigned to ac_precious_vars.
11942 (_AC_ARG_VAR_STORE): New macro which writes to diversion PARSE_ARGS
11943 a loop to assign all ac_env_* and ac_cv_env_* variables.
11944 (_AC_ARG_VAR_VALIDATE): Use shell variable ac_precious_vars, divert
11946 (_AC_INIT_DEFAULTS): At the end, if _AC_PRECIOUS_VARS is set, assign
11947 its value to shell variable ac_precious_vars and call
11948 _AC_ARG_VAR_STORE and _AC_ARG_VAR_VALIDATE.
11949 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Don't call
11950 _AC_ARG_VAR_VALIDATE.
11952 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Move AC_LANG_PUSH(C)
11953 and the AC_SUBSTs ...

11971 They are generated by the Tru64 v5.1B shell.
11973 2005-07-05 Stepan Kasal <kasal@ucw.cz>
11975 Fix my changes from 2005-07-01; reported by Noah Misch.
11976 * lib/autoconf/status.m4 (_AC_CONFIG_DEPENDENCIES): Fix the
11977 description, the macro now accepts only a single tag.
11978 (_AC_CONFIG_UNIQUE): Likewise; s/AC_File/[$1]/
11980 Fix cases when the varsions of Autoconf and Autotest don't match.
11981 Reported by Noah Misch.
11982 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Set also
11983 at_top_builddir, for compatibility with older autotest.
11984 * lib/autotest/general.m4 (AT_INIT): If at_top_build_prefix
11985 is not set, use at_top_builddir, for compatibility with older
11986 versions of autoconf.
11988 2005-07-04 Paul Eggert <eggert@cs.ucla.edu>
11990 * bin/autom4te.in ($m4): Catch usages like --nesting-limit=2048.
11991 Problem reported by Patrick Welche.
11993 2005-07-03 Paul Eggert <eggert@cs.ucla.edu>
11995 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Use &, not |, in
11996 sed substitution command, so that we allow | in program prefixes
11997 and program suffixes. (& is a problem anyway; we're not fixing
11999 * lib/autoconf/status.m4 (AC_CONFIG_FILES): Likewise, for
12000 configure_input, top_builddir, srcdir, etc.
12001 * lib/autotest/general.m4 (AT_INIT): Likewise, for

12004 2005-07-02 Alexandre Duret-Lutz <adl@gnu.org>
12006 * lib/autoconf/general.m4 (AC_SITE_LOAD): Rewrite the
12007 for loop over config.site files using `set', to allow
12008 directory names containing IFS characters.
12010 2005-07-01 Paul Eggert <eggert@cs.ucla.edu>
12012 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Remove the tests for
12013 directories with weird names. Apparently some people like living
12014 on the edge. However, improve the test that "pwd" actually does
12015 report a name for the working directory.
12016 * NEWS: Remove the claim that we test for funny chars in dir names.
12018 2005-07-01 Stepan Kasal <kasal@ucw.cz>

12032 (Limitations of Usual Tools) <sed>: Another minor rephrasing.
12034 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Use a here
12035 document to output the default config_* lists to config.status.
12036 Don't recognize option --file, if the functionality is not there.
12037 Likewise for --header; moreover, recognize --he and --h as shortcuts
12038 for --help in that case.
12040 * lib/autoconf/status.m4: Fix the order of the "sections", so that it
12041 matches the order of execution. No code changed.

12060 * lib/autoconf/general.m4 (AC_ARG_VAR): Move next to _AC_ARG_PRECIOUS.
12062 * lib/autoconf/general.m4 (AC_SUBST_TRACE): New macro, to be traced
12063 instead of AC_SUBST; proposed by Alexandre Duret-Lutz.
12064 (AC_SUBST): Call it.
12065 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Call AC_SUBST_TRACE for
12066 the directory specific variables; but don't call it for configure_input.
12068 2005-06-28 Derek Price <derek@ximbiot.com>
12070 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: Reword recent
12073 2005-06-23 Paul Eggert <eggert@cs.ucla.edu>
12075 * NEWS: Don't worry about spaces in bindir etc. Only srcdir and working
12076 directory have inherent problems with special characters like spaces,
12077 due to limitations in Make syntax. Problem reported by Alexandre
12079 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Implement the above.
12080 Also, fix Tru64 porting problem with shell patterns,

12091 Fix some more shell quoting problems. Prompted by a bug report
12092 from Justace Clutter.
12093 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Put name of invalid
12094 variable into diagnostic. Make the diagnostic an error, not a warning,
12095 because we really don't support spaces and suchlike in dir names.
12096 (_AC_INIT_SRCDIR): Allow special characters in $ac_unique_file.
12097 Don't worry about backslashes in srcdir; it can't happen now.

12099 Simplify ac_optarg handling.
12100 (_AC_ARG_VAR_VALIDATE): Remove unnecessary and inconsistent quotes.

12107 * tests/local.at (AT_CHECK_ENV): Use $EGREP, not $GREP -E.
12108 (AT_CONFIG_CMP): Use sed instead of grep plumbing.
12110 * doc/autoconf.texi (Limitations of Usual Tools) <grep>: Mention
12111 that '\|' is not allowed in BREs; recommend using newline separated
12112 list of patterns instead of multiple -e options.
12114 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Remove an old comment.
12116 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Use AC_SUBST/2.

12122 2005-06-21 Stepan Kasal <kasal@ucw.cz>
12124 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: Document that
12125 b, t, r, w commands require single space, while : cannot have any.
12126 (Special Shell Variables): Fix sed code this in the example.
12127 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Likewise; and fix a typo.
12128 * lib/autotest/general.m4 (AT_ARG_OPTION): Fix typo in the description.
12130 * lib/m4sugar/m4sugar.m4 (m4_split): If the parameter is empty,
12131 expand to the empty list. Don't use two pairs of m4_changequote,
12132 it's not necessary.
12134 2005-06-20 Derek Price <derek@ximbiot.com>
12136 * lib/m4/programs.m4 (AC_PROG_YACC): Declare YACC & YFLAGS precious.
12138 2005-06-17 Paul Eggert <eggert@cs.ucla.edu>
12140 * lib/m4sugar/m4sh.m4 (as_awk_strverscmp): Port to Solaris /bin/awk.
12141 * doc/autoconf.texi:
12142 Don't mention Solaris versions so much, if a
12143 problem is common to all extant versions of Solaris. Say "SunOS
12144 4" instead of "SunOS" for SunOS 4.
12145 (awk): Mention more of the limitations of traditional Awk.
12146 (cat): Don't talk about cat -v.
12148 2005-06-16 Paul Eggert <eggert@cs.ucla.edu>
12150 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE): New macro.
12151 (AS_VERSION_COMPARE): New macro. The API is taken from CVS,

12153 to be compatible with glibc strverscmp.
12154 * tests/m4sh.at (AS_VERSION_COMPARE): New test.
12156 * doc/autoconf.texi (Limitations of Usual Tools): Mention expr bug

12159 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT):
12160 Use shell builtins rather than 'expr', to work around expr bug.
12162 2005-06-10 Paul Eggert <eggert@cs.ucla.edu>
12164 * doc/autoconf.texi: "filesystem" -> "file system".
12165 "behaviour" -> "behavior".
12166 Warn about \(...\)* in Solaris sed (written by Ralf Menzel).
12167 * lib/autoconf/general.m4: Omit blank after ":" sed command,
12169 * lib/m4sugar/m4sh.m4: Likewise.
12170 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Work around problem
12171 with Solaris sed. Fix by Ralf Menzel and Stepan Kasal.
12173 * man/Makefile.am (MOSTLYCLEANFILES): Add $(srcdir)/*.t.
12174 (.x.1): Ignore the time stamp in the .TH line when deciding whether
12175 to update the man page. That way, we don't have to check in new
12176 man pages every month.
12178 * lib/m4sugar/m4sh.m4 (AS_VAR_TEST_SET): Work even if $1 contains
12179 quotes and backslashes. Patch from Derek Price.
12181 2005-06-10 Derek Price <derek@ximbiot.com>
12183 * doc/autoconf.texi (Programming in M4sh): Document AS_TR_CPP &

12188 * lib/autotest/general.m4 (AT_INIT): Don't accept Solaris 9's diff
12189 -u, since it outputs chatter if the input files are the same.
12190 Problem reported by Ralf Menzel.
12192 2005-06-08 Derek Price <derek@ximbiot.com>
12194 * lib/m4sugar/m4sugar.m4: Undefine include & sinclude rather than
12195 renaming them since they are about to be redefined anyhow.
12197 2005-06-08 Derek Price <derek@ximbiot.com>
12199 * doc/autoconf.texi (Redefined M4 Macros): Add index entries for most
12200 redefined M4 macros to this node. Document m4_include & m4_sinclude.
12201 Move m4_undefine to alphabetical order.
12203 2005-06-07 Paul Eggert <eggert@cs.ucla.edu>
12205 * README: Recommend GNU M4 1.4.3 or later.
12206 * doc/autoconf.texi (Introduction): Likewise.
12207 Reword to avoid some formatting glitches.
12208 Use "#!/bin/sh", not "#! /bin/sh"; the space isn't needed these days.
12209 Clarify explanation of HP compiler bug.
12210 Redo example output tp match current CVS snapshot.
12211 Use @example.org in email addresses when the examples
12212 might get inadvertently cut-and-pasted into user code.
12213 Remove example of autom4te usage that doesn't seem to work now.
12214 Use modern AC_INIT (except when the example is meant to be
12215 shown with Autoconf 2.13).
12216 Update ksh info for Solaris 9 and later.
12218 Modernize description of Automake versions a bit.
12219 Don't claim a future version of Autoconf is near.
12220 * doc/install.texi: Reword to avoid some formatting glitches.
12222 2005-06-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
12224 * doc/autoconf.texi: Add [] to examples, so that the manual
12225 follows its own advice about quoting better.
12226 Reword to avoid some formatting glitches.
12227 * doc/installt.exi: Reword to avoid some formatting glitches.
12229 * doc/autoconf.texi (Limitations of Builtins) <case>: Mention
12230 Tru64 ksh pattern matching bug. Reported against Libtool by
12231 Albert Chin <libtool@mlists.thewrittenword.com> and
12232 Nicolas Joly <njoly@pasteur.fr>.
12234 2005-06-06 Stepan Kasal <kasal@ucw.cz>
12236 m4_cdr of one-member list was [[]] (one-member list containing an
12237 empty string) instead of [] (an empty list. Callers were skewed to
12238 match this misbehaviour. As a consequence of this:
12239 - m4_foreach([x], [], [foo]) expanded to `foo', while
12240 - the expansion of m4_foreach([x], [[]], [foo]) was empty.
12241 This bug has been fixed:
12243 * lib/m4sugar/m4sugar.m4 (m4_cdr): If only one argument is given,
12244 expand to an empty string; print error msg if called without
12246 (m4_foreach, m4_map, m4_map_sep): Don't expect the previous
12247 misbehaviour; handle [] and [[]] correctly.
12249 2005-06-06 Stepan Kasal <kasal@ucw.cz>
12251 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Nuke ac_max_here_lines.
12252 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Simplify the sed
12253 scripts created and the loop applying them, use _AC_SED_CMD_LIMIT.
12255 2005-06-06 Ralf Menzel <menzel@ls6.cs.uni-dortmund.de> (trivial change)
12257 * doc/autoconf.texi (Limitations of Usual Tools): Solaris' awk cannot
12258 swallow records with more than 99 fields.
12259 * lib/autotest/general.m4 (AT_INIT): Use the awk builtin `split' to
12260 parse the long line.
12262 2005-06-04 Stepan Kasal <kasal@ucw.cz>
12264 * doc/autoconf.texi (Limitations of Usual Tools): AIX awk cannot
12265 swallow literals longer than 399. Reported by Ralf Wildenhues.
12266 * lib/autotest/general.m4 (AT_INIT): Pass $at_groups though stdin,
12267 to workaround this limitation.
12269 2005-06-03 Steven G. Johnson <stevenj@alum.mit.edu>
12271 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Find g95 in addition
12272 to gfortran, and make these the first two compiler names
12273 checked (following the general autoconf preference for gcc).
12275 2005-06-03 Stepan Kasal <kasal@ucw.cz>
12277 * tests/Makefile.am (check_SCRIPTS): Set to $(wrappers).
12278 (DISTCLEANFILES): Remove $(check_SCRIPTS).

12281 2005-06-02 Paul Eggert <eggert@cs.ucla.edu>
12283 * lib/autotest/general.m4 (AT_INIT): Don't create a regular
12284 expression of unbounded size when processing the --list
12285 option. This runs afoul of a limit of 399 bytes per regular
12286 expression on AIX. Problem reported by Ralf Wildenhues.
12288 2005-06-01 Paul Eggert <eggert@cs.ucla.edu>

12291 * doc/autoconf.texi (Particular Headers): Reword example
12292 for multiline stdbool replacement.
12293 (Setting Output Variables): Reword text a bit. Don't
12294 give all the details about |#_!!_#|.
12295 Reword description of line replacement.
12297 2005-05-31 Dan Manthey <dan_manthey@partech.com>
12299 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Output variables may
12300 now contain newlines, and substituted files must be referenced on
12301 a line alone; the sed scripts to substitute them are now very
12303 (_AC_SED_CMD_LIMIT): Added; single place to store limit on how many
12304 commands can be put in a sed script portably.
12305 * doc/autoconf.texi (Setting Output Variables): Document above
12306 changes. (Particular Header Checks) <AC_HEADER_STDBOOL>: Give exaple
12307 use of multiline substitution.

12313 From Ralf Menzel (trivial change).
12315 2005-05-25 Paul Eggert <eggert@cs.ucla.edu>
12317 * tests/local.at: Don't attempt to check for negated character
12318 classes in shell scripts. The test was too brittle.
12320 2005-05-25 Stepan Kasal <kasal@ucw.cz>
12322 * bin/autoconf.as: Don't use "shift 2"; it's not portable enough.
12323 * doc/autoconf.texi (Limitations of Builtins): Document this
12326 2005-05-24 Stepan Kasal <kasal@ucw.cz>
12328 * lib/m4sugar/m4sh.m4 (_AS_ECHO_LOG): New macro to factor out

12333 * lib/m4sugar/m4sugar.m4 (m4_ifset): Use m4_ifval.
12335 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Merge the two error
12336 messages when ac_unique_file is not found.
12337 (AC_CONFIG_MACRO_DIR): Simplify the `if' at the end.
12338 (AC_MSG_CHECKING, AC_MSG_RESULT): Put braces around the two echo
12339 commands, for consistency with AC_MSG_ERROR and such.
12341 * bin/autoconf.as: Make more use of "shift 2" in option processing.
12343 * bin/Makefile.am: Merge the two rules for creating scripts.

12351 2005-05-20 Stepan Kasal <kasal@ucw.cz>
12353 * NEWS: @top_builddir@ is now a dirname, ac_top_builddir will follow.
12354 * lib/autoconf/status.m4 (_AC_SRCDIRS): Rename ...
12355 (ac_top_builddir): ... this ...
12356 (ac_top_build_prefix): ... to this; the old name is also kept, for
12357 backward compatibility.
12358 (ac_top_builddir_sub): New variable, without the trailing slash,
12360 (_AC_OUTPUT_FILES): s/@top_builddir@/$ac_top_builddir_sub/
12361 * doc/autoconf.texi (Configuration Actions): Rename
12362 ac_top_builddir to ac_top_build_prefix.

12374 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Don't m4_quote the second
12375 argument to m4_foreach. I guess it was necessary in the past,
12376 but I think it's a no-op now.
12378 2005-05-17 Stepan Kasal <kasal@ucw.cz>
12380 * lib/autoconf/general.m4 (_AC_INIT_HELP): Merge two consecutive
12381 ``cat <<_ACEOF'' commands to one.
12382 (_AC_CANONICAL_SPLIT): Use expr, not ``echo|sed.''
12383 * lib/autoconf/status.m4: On various places, use expr instead of
12385 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST):
12386 (_AC_CONFIG_SPLIT_FILE_IN): New macros, to factor out common code.

12389 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Use awk to search for
12390 the wrong patterns between ``case'' and ``esac.'' The previous
12391 code had false positives.

12455 abbreviations of --version and --debug.
12457 2005-05-10 Paul Eggert <eggert@cs.ucla.edu>
12459 * doc/autoconf.texi (Autoconf Language): Be more precise about
12460 quoting rules. Problems noted by Stepan Kasal.
12461 Also, throughout this document, be more careful about white space.
12462 "blank", "white space", and "space" all have different meanings
12463 and we should be careful to say what we mean.
12465 2005-05-05 Paul Eggert <eggert@cs.ucla.edu>

12484 set by latest automake.
12486 2005-05-01 Paul Eggert <eggert@cs.ucla.edu>
12488 * doc/autoconf.texi (Limitations of Usual Tools): "expr '' \| ''"
12489 outputs 0 on GNU/Linux these days.
12491 2005-04-29 Paul Eggert <eggert@cs.ucla.edu>
12493 * doc/autoconf.texi (Autoconf Language): Add more description
12494 about quoting heuristics.
12495 (Limitations of Builtins): Describe "set -" problems.
12497 2005-04-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
12499 * lib/autotest/general.m4 (AT_KEYWORDS): Separate by space,
12502 * doc/autoconf.texi (External Software): Replace AC_DEFINE_UNQUOTED
12503 by AC_DEFINE; it was a mistake.
12504 From bug reported against libtool by Dalibor Topic <robilad@kaffe.org>.
12506 2005-04-25 Stepan Kasal <kasal@ucw.cz>
12508 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): A tiny optimization.
12510 2005-04-22 Stepan Kasal <kasal@ucw.cz>
12512 * doc/autoconf.texi (External Software): Quadrigraphs are not
12513 processed correctly in AS_HELP_STRING; avoid this in the examples.
12514 * lib/m4sugar/m4sh.m4 (AS_HELP_STRING): Add a FIXME about quadrigraphs.
12515 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Likewise; and rephrase the
12516 comment and reduce m4_default([foo], []) to [foo].
12517 (m4_strip): Update the explanation.
12519 2005-04-19 Paul Eggert <eggert@cs.ucla.edu>
12521 * lib/autoconf/general.m4 (_AC_INIT_PREPARE, _AC_RUN_IFELSE):
12522 Remove core.conftest.* too; it's generated by Tru64 5.1.
12523 Problem reported by Jennis Pruett.
12524 * lib/autoconf/functions.m4
12525 (AC_FUNC_SETVBUF_REVERSED, AC_FUNC_UTIME_NULL):
12526 Don't bother to remove core files; AC_RUN_IFELSE should do that
12529 2005-04-19 Stepan Kasal <kasal@ucw.cz>
12531 * lib/m4sugar/m4sugar.m4 (m4_bpatsubsts): Add the b- to comment, too.

12548 2005-04-13 Paul Eggert <eggert@cs.ucla.edu>
12550 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Look for configure.ac
12551 as well as configure.in. Problem reported by Gregorio Guidi.
12553 2005-04-10 Paul Eggert <eggert@cs.ucla.edu>
12555 * doc/autoconf.texi (Particular Functions): Use gnulib's current

12571 2005-03-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
12573 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS):
12574 Merge `-z option' as well for the benefit of Solaris link flags. Pass
12575 whole-archive (-zallextract, -zdefaultextract) options in the hope of
12576 unique libraries, for the Sun Fortran 95 8.0 compiler. Bug reported
12577 against Libtool by Yury Puhalsky <pooh@cryptopro.ru>.
12579 2005-03-22 Paul Eggert <eggert@cs.ucla.edu>
12581 * NEWS: The configure command now warns you if you attempt to use
12582 a directory whose name contains a special character like space,
12584 * doc/autoconf.texi (Installation Directory Variables): Allow
12585 "," in file names. Do not use \@; it's not a portable regexp.
12586 * bin/Makefile.am (edit): Likewise.
12587 * lib/Makefile.am (edit): Likewise.

12594 unportable file names.
12595 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): New macro.
12597 (_AC_INIT_SRCDIR): Use ac_pwd rather than invoking pwd.
12598 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Propagate
12599 ac_pwd, and quote srcdir.
12600 * lib/autotest/general.m4 (AT_INIT): Quote file name args.
12602 * doc/autoconf.texi: Fix some systematic formatting problems.
12603 ".)" needs a following @: if not at the end of a sentence, and
12604 similarly for "!)". "etc." should be preceded by a comma.
12605 "n-th" -> "@var{n}th". pdksh is still buggy, so update its date.
12607 2005-03-22 Bruno Haible <bruno@clisp.org>
12609 * doc/autoconf.texi (Input): Mention that AC_CONFIG_AUX_DIR's
12610 argument is often called 'build-aux'.
12612 2005-03-07 Stepan Kasal <kasal@ucw.cz>
12614 * doc/autoconf.texi (Quotation Rule Of Thumb): Mention that the
12615 macro AC_TRY_LINK is obsolete.
12616 (Installation Directory Variables): Change `AC_OUTPUT_FILES' to
12619 2005-02-24 Stepan Kasal <kasal@ucw.cz>
12621 * lib/autoconf/c.m4 (AC_PROG_CC): Be more careful to skip
12622 `/usr/ucb/cc'; use `cl.exe' to distinguish the MS compiler
12623 from a Common Lisp's `cl'.
12624 (AC_PROG_CXX): Behave according to the documentation: don't
12625 search for $ac_tool_prefix$CCC and $CCC, just set CXX=$CCC;
12626 make the variable CCC precious; use `cl.exe', not `cl'.
12628 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
12629 Alexandre Duret-Lutz <adl@gnu.org>
12631 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin from
12632 /dev/null, as "configure" shouldn't read stdin, and this insulates
12633 us from problems (e.g., when testing for "cl"). Also, do this
12634 redirection before invoking "hostname" or "uname", and keep the
12635 original input stream available via...
12636 (AS_ORIGINAL_STDIN_FD): ... this new macro.
12637 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't
12638 bother with "</dev/null" since it's now done at the top of

12647 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
12649 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N_PREPARE): Don't set ECHO_C to
12650 newline if neither \c nor -n work, as that would output two
12651 newlines. Prefer -n to \c. Reported by Stepan Kasal.
12653 2005-02-12 Stepan Kasal <kasal@ucw.cz>
12655 * lib/m4sugar/m4sh.m4 (AS_IF): Define by m4_defun, not m4_define.
12656 This causes that any required macros inside will get before the if.
12657 * doc/autoconf.texi (autom4te.cache): A typo.
12659 2005-02-12 Paul Eggert <eggert@cs.ucla.edu>
12661 Undo previous change, except keep the change to
12662 lib/autoconf/programs.m4 that replaced grep with shell
12663 pattern-matching. This is because net-snmp configure reads stdin.
12664 Reported by Noah Misch.
12666 2005-02-11 Paul Eggert <eggert@cs.ucla.edu>
12668 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin
12669 from /dev/null, as "configure" shouldn't read stdin, and this
12670 insulates us from problems (e.g., when testing for "cl").
12671 Suggested by Alexandre Duret-Lutz. Also, do this redirection
12672 before invoking "hostname" or "uname".
12673 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
12674 _AC_LINK_IFELSE): Undo previous change, as it's no longer needed.
12675 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Don't bother with
12676 "</dev/null" since it's now done at the top of 'configure'.
12677 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
12678 * lib/autoconf/programs.m4 (_AC_PATH_PROG_FLAVOR_GNU): Likewise.
12679 Also, replace grep with shell pattern-matching, to save a process.
12681 2005-02-10 Paul Eggert <eggert@cs.ucla.edu>
12683 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
12684 _AC_LINK_IFELSE): Redirect stdin to /dev/null, in an attempt to
12685 avoid thinking that Allegro Common Lisp's "cl" command is a C++
12688 2005-02-09 Paul Eggert <eggert@cs.ucla.edu>
12690 * doc/autoconf.texi (Limitations of Usual Tools): Document that
12691 grep -q isn't portable. Improve grep -s explanation.
12692 Problem reported by Dan Manthey.
12694 2005-02-08 Paul Eggert <eggert@cs.ucla.edu>
12696 * doc/autoconf.texi (Special Shell Variables): Clarify
12697 PATH_SEPARATOR wording; fix typo in IFS. Reported by Gary V. Vaughan.
12699 2005-02-07 Paul Eggert <eggert@cs.ucla.edu>
12701 * doc/autoconf.texi: Use @acronym for DJGPP.
12702 Fix some @code's that should have been @env's, and vice versa.
12703 Sort environment variable names.
12704 Mention that shells no longer inherit IFS.
12705 Don't recommend PATH_SEPARATOR=';' so strongly.
12706 Mention that $RANDOM might expand to the empty string.
12707 "symlink" and "soft link" -> "symbolic link".
12708 Improve mktemp description (reported by Bruno Haible).
12710 2005-02-05 Paul Eggert <eggert@cs.ucla.edu>
12712 * tests/foreign.at (Libtool): Don't overquote AT_SETUP arg.
12713 * tests/m4sh.at (AS_DIRNAME, AS_BASENAME, AS_MKDIR_P, AS_HELP_STRING):
12715 * tests/semantics.at (AC_C_BIGENDIAN, AC_PATH_PROG & AC_PATH_PROGS):
12718 2005-02-04 Paul Eggert <eggert@cs.ucla.edu>
12720 * NEWS: Mention AT_COPYRIGHT.
12722 * tests/local.at (AT_CMP): Use diff directly on input files rather
12725 * lib/autoconf/programs.m4 (AC_PROG_SED): Don't look in
12726 /usr/xpg4/bin since that sed dumps core (at least on Solaris 8).
12728 2005-02-04 Noah Misch <noah@cs.caltech.edu>
12729 and Paul Eggert <eggert@cs.ucla.edu>

12738 * lib/m4sugar/m4sugar.m4 (m4_re_string, m4_re_word): Revert 2002-03-04.
12739 * tests/local.at (AT_CHECK_M4SUGAR): Add `m4sugar' to keywords.
12740 (AT_CHECK_ENV): Ignore LTLIBOBJS, FC variables, EGREP, FGREP, and SED.

12743 (m4_warn, m4_require: circular dependencies, m4_text_wrap): Strip
12744 excess test name quoting.
12745 * tests/semantics.at (AC_CHECK_HEADERS_OLD, AC_CHECK_HEADERS_NEW): Pass
12746 CPPFLAGS to `configure' instead of setting it in `configure'.
12748 * lib/m4sugar/m4sh.m4 (AS_UNAME): Try only /usr/bin/hostinfo, not
12749 any `hostinfo' in $PATH, since hostinfo.exe is a popular file name
12752 * lib/autoconf/fortran.m4 (AC_LANG(Fortran), AC_FC_SRCEXT):
12753 s/FC_SRCEXT/ac_fc_srcext/; s/FCFLAGS_SRCEXT/ac_fcflags_srcext/.

12783 * lib/m4sugar/m4sugar.m4 (m4_re_escape): Escape ?, ^, \, $ too;
12784 this fixes a bug tickled by the AT_CAPTURE_FILE change noted below.
12786 Try not to generated lines of unlimited length, as POSIX places a
12787 2047-byte limit on line length of portable text files.
12788 * lib/autoconf/general.m4 (AC_SUBST, AC_SUBST_FILE):
12789 Use newline as a separator, not space.

12802 * doc/autoconf.texi (Special Shell Variables): Mention _,
12803 BIN_SH, DUALCASE. Say that variables other than "status" are safe
12804 if they contain a lower-case letter. The DUALCASE problem was
12805 reported by Ralf Wildenhues.
12807 * bin/autoconf.as: Don't exit with status 0 after write failure
12808 with --help or --version.

12814 * doc/autoconf.texi (Limitations of Usual Tools):
12815 Unicos 9 sed limitations.
12816 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Try cf77 before fort77
12817 to get the option-enhanced interface on older Crays. Try ftn for
12818 Fortran 95 (newer Crays).
12820 2005-02-01 Paul Eggert <eggert@cs.ucla.edu>
12822 * man/Makefile.am (.x.1): Go back to the simple solution, but take
12823 care to echo the commands, so the user knows what's going on.
12824 Modified from a suggestion by Stepan Kasal.

12834 Based on a proposed patch by Ralf Wildenhues.
12836 * man/Makefile.am (.x.1): Make sure the required generated files

12847 Simplify the implementation of m4_require (a.k.a. AC_REQUIRE).
12848 Update the long comment explaining it.
12850 m4_require no longer writes an ``is required by'' line to the
12851 execution stack. It contains only one bit of non-redundant
12852 information: that the macro was required, not called. And even
12853 this bit is useless in most situations: have you ever met a macro
12854 which both calls and requires the same macro?
12856 * lib/m4sugar/m4sugar.m4 (_m4_defun_pro): Don't push a diversion...
12857 (_m4_defun_pro_outer): ... only via this macro, for the outermost
12859 (_m4_defun_epi, _m4_defun_epi_outer): Complementarily.

13276 * lib/autoconf/functions.m4 (AC_FUNC_MEMCMP): Use
13277 "char c = '\200';" rather than "char c = 0x80;" as the

13340 2004-11-13 Stepan Kasal <kasal@ucw.cz>
13342 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Don't check
13343 the $1_found variable, don't test whether the file is executable;
13344 Both things are checked ...
13345 (_AC_PATH_PROG_FEATURE_CHECK): ... here; AS_EXECUTABLE_P replaces
13346 the former ``test -f''.
13347 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Fix a typo.
13349 2004-11-10 Paul Eggert <eggert@cs.ucla.edu>

13356 * doc/autoconf.texi (Limitations of Usual Tools): Note `cp -r'
13357 limitations. Reorder paragraphs for clarity.
13359 2004-10-11 Paul Eggert <eggert@cs.ucla.edu>
13361 * doc/autoconf.texi: Standardize spelling of "Posix" (as opposed
13362 to "POSIX" or "@acronym{POSIX}"), and similarly for "DOS
13363 variants", "Unix", and some related minor wording fixups.

13381 (AU_DEFUN): Use it to fix the bug when the index contained AC_AU_DEFUN.
13382 Problem reported by Stepan Kasal.
13384 2004-09-05 Paul Eggert <eggert@cs.ucla.edu>
13386 Fix problems reported by Andreas Buening in:

13388 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Set SHELL=/bin/sh
13390 * lib/autotest/general.m4 (AT_INIT): Don't assume /dev/null is
13391 readable; it's not true in OS/2-emx.
13393 2004-09-04 Paul Eggert <eggert@cs.ucla.edu>
13395 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): If xmkmf returns
13396 "/usr/include", clear ac_x_includes instead of leaving it as "no"
13397 (trivial change). Problem and patch reported by Andrew Church in:
13398 http://lists.gnu.org/archive/html/bug-autoconf/2004-04/msg00016.html
13400 2004-09-03 Paul Eggert <eggert@cs.ucla.edu>

13428 texinfo.tex for now (done by hand now).
13429 * Makefile.maint (wget_files, cvs_files):
13430 Remove ansi2knr.c; nobody uses it.
13431 (ansi2knr.c-url_prefix): Remove.
13432 (cvs-update): Fix test for failure. I don't know why it ever
13435 * doc/autoconf.texi: Update URLs, some of which went stale.
13436 Use @uref rather than @href.
13438 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Have configure
13439 handle "--" as per POSIX. Suggested by Paul Pogonyshev.
13441 * config/config.guess, config/config.sub, config/elisp-comp,
13442 config/install-sh, config/mkinstalldirs, config/texinfo.tex,
13443 doc/fdl.texi, doc/standards.texi: Sync with master copy.

13452 tests/tools.at, tests/torture.at:
13453 Use "file name" rather than "filename" or "path",
13454 to be consistent with the terminology of the GNU coding standards.
13456 2004-08-19 Paul Eggert <eggert@cs.ucla.edu>
13458 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C),
13459 AC_C_LONG_DOUBLE): Undo 2004-06-04 change, as it didn't work with
13460 HP-UX 11.23 cc/aCC or Tru64 4.0 cc. Problem reported by Noah Misch in
13461 <http://lists.gnu.org/archive/html/autoconf/2004-07/msg00004.html>.
13463 More fixes to support spaces in the name of the build directory.
13464 This isn't a complete fix but it's an improvement.
13466 * bin/autoconf.as (autom4te_options): New var.
13467 Use it instead of appending to AUTOM4TE, so that we can allow
13468 spaces in the build directory's absolute name.
13469 * bin/autoheader.in ($autoconf): Allow spaces in file names.
13470 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP, _AT_CHECK,
13471 AT_CHECK_NOESCAPE): Likewise.
13472 * tests/wrapper.as (testdir, AUTOM4TE_CFG, autom4te_perllibdir,
13473 main program): Likewise.
13475 2004-08-18 Paul Eggert <eggert@cs.ucla.edu>

13483 * doc/autoconf.texi (Function Portability): Document isinf and
13484 and isnan. From a suggestion by Kevin Ryde.
13486 * lib/Autom4te/General.pm (END): Return correct exit status even
13487 if unlink succeeds and sets $?. Needed with Solaris 8's perl 5.00503.
13489 2004-08-09 Paul Eggert <eggert@cs.ucla.edu>
13491 * tests/torture.at (Deep Package): Use configure.in, not configure.ac,
13492 for compatibility with Automake 1.4. Reported by J C Fitzgerald in
13493 <http://lists.gnu.org/archive/html/bug-autoconf/2003-08/msg00051.html>.
13495 2004-08-04 Alexandre Duret-Lutz <adl@gnu.org>
13497 * lib/autoconf/general.m4 (AC_REQUIRE_AUX_FILE): New empty macro.
13498 (AC_CANONICAL_BUILD): Call it to require config.sub and config.guess.
13499 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Likewise for install-sh.
13500 * doc/autoconf.texi (Input): Document AC_REQUIRE_AUX_FILE.
13501 * lib/autom4te.in (Automake-preselections): Preselect
13502 AC_REQUIRE_AUX_FILE. Automake 1.10 will trace it.
13504 2004-08-02 Alexandre Duret-Lutz <adl@gnu.org>
13506 * lib/autom4te.in (Automake-preselections): Preselect
13507 AC_CANONICAL_BUILD and AC_CANONICAL_TARGET. Automake 1.9.1 will
13510 2004-07-29 Paul Eggert <eggert@cs.ucla.edu>
13512 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): Set BIN_SH, for

13515 Document problem with "`""`" in pdksh POSIX mode.
13517 2004-07-27 Paul Eggert <eggert@cs.ucla.edu>
13519 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): Use "set -o posix"
13520 with pdksh, too. Problem reported by Patrick Welche via
13522 * doc/autoconf.texi (Shellology): Note that set -o posix is
13523 useful for pkdsh, too.
13525 2004-06-24 Paul Eggert <eggert@cs.ucla.edu>
13527 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Require
13528 _AS_UNSET_PREPARE, so that we can use $as_unset directly.
13529 Don't fail if ENV or BASH_ENV is readonly.
13530 (AS_SHELL_SANITIZE): Don't fail if ENV, MAIL, MAILPATH, LC_ALL,
13531 etc. are read only. Problem reported by Ludovic Courtes.
13533 2004-06-23 Noah Misch <noah@cs.caltech.edu>
13535 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): If the shell is
13536 zsh, disable GLOB_SUBST to avoid backslash handling problems.
13539 2004-06-04 Paul Eggert <eggert@cs.ucla.edu>
13541 * doc/autoconf.texi (File System Conventions): Warn about
13542 names like "aux". Problem reported by Eric Blake.
13544 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY (C)): Use division
13545 by zero instead of array size, so that we can use any arithmetic
13546 constant expression (instead of requiring an integer constant
13547 expression). This allows us to test expressions like DBL_MAX <
13548 LDBL_MAX, which didn't conform to the C standard using the old
13550 (AC_C_LONG_DOUBLE): Put back in the tests for LDBL_MAX and LDBL_EPSILON,
13551 now that we can do floating-point tests at compile time.
13553 2004-06-02 Paul Eggert <eggert@cs.ucla.edu>
13555 * lib/autoconf/c.m4 (AC_C_LONG_DOUBLE): Don't check LDBL_MAX
13556 and LDBL_EPSILON, as the resulting expression isn't an
13557 integer constant expression and violates the C standard.
13558 Problem reported by Nelson H. F. Beebe. Also, check
13559 for "L" suffix, and check that long double doesn't have
13560 worse range or precision than double, that mixed-mode
13561 arithmetic doesn't generate a diagnostic, that double
13562 constants fit in long double.
13564 2004-06-03 Kevin Ryde <user42@zip.com.au>
13566 * doc/autoconf.texi (Function Portability): Add notes on free(NULL),
13567 malloc(0) and realloc(NULL,size).
13569 * doc/autoconf.texi (Shell Substitutions): Spelling error reported by
13572 2004-05-31 Paul Eggert <eggert@cs.ucla.edu>
13574 * lib/autoconf/headers.m4 (HAVE_STDBOOL_H): Detect _Bool bug
13575 in HP aC++/ANSI C B3910B A.05.55 [Dec 04 2003]. Problem reported
13578 2004-05-26 Paul Eggert <eggert@cs.ucla.edu>
13580 * doc/autoconf.texi (Limitations of Builtins): Mention that ! COMMAND
13581 can be rewritten using if-then-else. Suggested by Bruno Haible.
13583 2004-05-25 Paul Eggert <eggert@cs.ucla.edu>
13585 * doc/autoconf.texi (testsuite Scripts): Fix typo.
13586 Problem reported by Stepan Kasal.
13588 2004-05-24 Paul Eggert <eggert@cs.ucla.edu>
13590 * tests/Makefile.am (autoconfdir): Fix to match comment (trivial
13591 change). Patch reported by Ralf Wildenhues in
13592 <http://mail.gnu.org/archive/html/bug-autoconf/2004-05/msg00092.html>.
13594 * lib/autoconf/functions.m4 (AC_FUNC_MBRTOWC): Don't assume that a
13595 function F exists if the compiler and linker let you compile an
13596 expression like (F != 0). Recent versions of GCC optimize away
13597 the reference to F in that case, since every function address must
13598 be nonzero, so the link succeeds even if F does not exist.
13599 Problem reported by Manu in
13600 <http://mail.gnu.org/archive/html/bug-gnu-utils/2004-05/msg00060.html>.
13602 * doc/autoconf.texi (Systemology): Standardize on the spelling of
13603 "Unix". Many uses changed.
13604 (Limitations of Builtins): Explain better why the ! command isn't
13607 2004-05-22 Alexandre Duret-Lutz <adl@gnu.org>
13609 * lib/autom4te.in (Automake-preselections): Preselect
13610 LT_SUPPORTED_TAG in lieu of AC_LIBTOOL_TAGS.
13612 2004-05-19 Kevin Ryde <user42@zip.com.au>
13614 * doc/autoconf.texi (Function Portability): Add strerror_r, cross
13615 referencing AC_FUNC_STRERROR_R.
13617 * doc/autoconf.texi (Particular Functions): In AC_FUNC_CLOSEDIR_VOID,
13618 note pessimistic assumption when cross compiling.
13620 2004-05-16 Paul Eggert <eggert@cs.ucla.edu>
13622 * doc/autoconf.texi (Limitations of Make): Note that BSD make
13623 (until 2004) invoked subcommands with sh -e, contra POSIX.
13624 Reported by Kevin Ryde.
13626 2004-05-10 Eric Sunshine <sunshine@sunshineco.com>
13628 * programs.m4 (_AC_PROG_GREP): Fixed bug where PATH argument handed to
13629 _AC_PATH_PROG_FEATURE_CHECK contained leading whitespace (i.e.
13630 " $PATH:/usr/xpg4/bin"). This resulted in bogus tests, such as
13631 `test -f " /usr/bin/grep"', which _always_ failed.
13632 (AC_PROG_SED): Ditto bogus PATH fix.
13633 * autoconf.texi (AC_PROG_GREP): Properly document that this macro
13634 requires that grep correctly supports _multiple_ `-e' options, rather
13635 than stating only that grep should accept `-e'.
13637 2004-05-03 Paul Eggert <eggert@cs.ucla.edu>
13639 Port to C99, which requires that 'exit' be declared.
13641 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Use AC_INCLUDES_DEFAULT
13642 to ensure that stdlib.h is included.
13643 * lib/autoconf/functions.m4 (_AC_LIBOBJ_ALLOCA, AC_FUNC_SETPGRP,
13644 AC_FUNC_STRTOD, AC_FUNC_SETVBUF_REVERSED, AC_FUNC_FORK, _AC_FUNC_FORK,
13645 _AC_FUNC_VFORK, AC_FUNC_WAIT3): Likewise.
13646 * lib/autoconf/specific.m4 (AC_SYS_RESTARTABLE_SYSCALLS): Likewise.
13647 * lib/autoconf/types.m4 (AC_TYPE_GETGROUPS): Likewise.
13648 * lib/autoconf/headers.m4 (AC_HEADER_STDC): Include <stdlib.h>
13649 when using 'exit' in a test; C99 requires that 'exit' be declared.
13651 2004-05-02 Paul Eggert <eggert@cs.ucla.edu>
13653 * doc/autoconf.texi (Particular Programs): AC_PROG_GREP
13654 now prefers 'grep' implementations that accept -e.
13655 (Limitations of Usual Tools): Describe problems of traditional
13656 egrep and fgrep with long input lines, and of traditional grep
13658 * lib/autoconf/programs.m4 (AC_PROG_GREP): Check for -e, too.
13659 (_AC_PROG_GREP): Assume 3rd arg is properly quoted for the shell.
13660 All callers changed. Append /usr/xpg4/bin to the PATH, for
13662 (_AC_FEATURE_CHECK_LENGTH): Discard stderr, so we don't bother
13663 the user with complaints about multiple -e options.
13664 * tests/local.at (AC_STATE_SAVE): Use $GREP, not grep.
13665 Define it with AC_PROG_GREP.
13666 * configure.ac (AC_PROG_GREP): Add.
13667 * lib/freeze.mk (GREP): New macro.
13669 2004-05-02 Eric Sunshine <sunshine@sunshineco.com>
13671 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Consult $SHELL as
13672 a possible candidate only after all others fail, rather than
13673 consulting it first. This improves backward compatibility by
13674 better reflecting the way shell selection occurred in previous
13675 versions of Autoconf, and should help to avoid triggering latent
13676 problems in other packages, such as the one in Automake where zsh
13677 is not handled robustly:
13678 http://mail.gnu.org/archive/html/automake/2004-04/msg00095.html
13679 Although it is not Autoconf's responsibility to work around
13680 problems in Automake, it nevertheless makes sense to avoid
13681 introducing unnecessary incompatibilites.
13683 2004-04-22 Albert Chin-A-Young <china@thewrittenword.com>,
13684 Gary V. Vaughan <gary@gnu.org>
13686 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Don't guess
13687 how deeply nested we are when a suitable tool is found, set the
13688 ac_path_TOOL_found flag.
13689 (_AC_PATH_PROG_FEATURE_CHECK): Encapsulate knowledge of how deeply
13690 nested we are in this macro. Break out of all 3 nested loops if
13691 ac_path_TOOL_found is set.
13693 2004-04-21 Gary V. Vaughan <gary@gnu.org>
13695 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Break out
13696 of the _AS_PATH_WALK loop too if GNU flavor is found.
13698 2004-04-21 Alexandre Duret-Lutz <adl@gnu.org>
13700 * doc/autoconf.texi (Limitations of Make): Update documentation
13701 for `$<'. New entry `Long lines', based on a report from Simon
13702 Josefsson. Augment the documentation for SHELL = @SHELL@ with a
13703 paragraph about DJGPP, based on a mail from Richard Dawe.
13705 2004-04-20 Paul Eggert <eggert@twinsun.com>
13707 * tests/c.at (C keywords): Don't assume that GCC supports
13708 "restrict" and "inline", as sufficiently-old GCC versions do not
13709 (also, GCC configured to be in pedantic C89 mode does not).
13710 Problem reported by Sumit Pandya in:
13711 http://mail.gnu.org/archive/html/autoconf/2004-04/msg00092.html
13713 * lib/autoconf/c.m4 (_AC_PROG_CC_G, _AC_PROG_CXX_G): Don't
13714 consider -g to work if it generates warnings when plain compiles
13715 don't. Problem reported by Braden McDaniel in:
13716 http://mail.gnu.org/archive/html/autoconf-patches/2003-07/msg00014.html
13718 * doc/autoconf.texi (Slashes): New section, to document a problem
13719 reported by Jim Meyering in:
13720 http://mail.gnu.org/archive/html/bug-coreutils/2004-02/msg00060.html
13722 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Remove potential
13723 linker output files before linking, to work around IRIX 6 linker bug.
13724 Problem reported by Rainer Orth in:
13725 http://mail.gnu.org/archive/html/autoconf-patches/2004-02/msg00007.html
13727 2004-04-20 Gary V. Vaughan <gary@gnu.org>
13729 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Make the
13730 best tool so far counter rely on the tool path variable name to
13731 avoid checks for one tool being affected by the results of running
13732 the length check on a previous tool.
13734 * lib/autoconf/programs.m4 (_AC_PROG_GREP): Take an additional
13735 match expression argument, as different greps have different
13736 regular expression flavours.
13737 (AC_PROG_FGREP): Pass 'FGREP'. fgrep treats all match chars as
13739 (AC_PROG_EGREP): Pass 'EGREP$'.
13740 (AC_PROG_GREP): Pass 'GREP$'.
13742 2004-04-20 Albert Chin-A-Young <china@thewrittenword.com>
13744 * lib/autoconf/programs.m4 (AC_PROG_GREP): Cache variable
13745 is `ac_cv_path_GREP', not `oc_cv_path_GREP'.
13747 2004-03-29 Paul Eggert <eggert@twinsun.com>
13749 * doc/autoconf.texi (Particular Headers, Particular Types, Generic

13863 * bin/Makefile.am ($(srcdir)/autoconf.in): Depend on

13872 AC_SUBST provides no portable way to escape literal newlines.
13874 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS): Ignore all
13875 flags of the form -lcrt*.o, not just -lcrt[01].o and -lcrtbegin.o.
13876 Darwin uses -lcrt2.o and there's little point to cataloging all
13877 the system variants. Partial fix reported by Andreas Waechter in:

13903 Paul Eggert <eggert@twinsun.com>
13905 * lib/m4sugar/m4sh.m4 (M4SH-SANITIZE): New diversion.
13906 (AS_INIT): Output shell initialization there. Removed optional
13907 parameter. Expand _AS_SHELL_FN_SPY.

13922 use AS_INIT_WITH_SHELL_FN.

13955 the 2003-05-22 change, which removed the older years from the list.
13956 * lib/autoconf/status.m4 (AC_OUTPUT): Update copyright date to 2004.

13969 _AC_PROG_GREP, and AC_PROG_SED.

14000 2004-01-26 Paul Eggert <eggert@twinsun.com>
14002 * doc/autoconf.texi (Default Includes): Include <stdint.h> even if
14003 HAVE_INTTYPES_H is defined. This is needed on Tru64 5.1b with
14004 Compac C V6.5-207 (dtk), which defines uintmax_t in <stdint.h> but
14005 not <inttypes.h>. Problem reported by Tim Mooney in
14006 <http://mail.gnu.org/archive/html/bug-coreutils/2004-01/msg00147.html>.
14007 * lib/autoconf/headers.m4 (_AC_INCLUDES_DEFAULT_REQUIREMENTS):
14010 * lib/autoconf/programs.m4 (AC_PROG_SED): Use diff, not sed;
14011 otherwise "make check" fails because it forbids cmp (I guess
14012 because cmp treats files as binary on DOS-like systems).
14014 * tests/mktests.sh: Update copyright date to 2004, since some tests
14015 have changed in 2004.
14017 2004-01-23 Gary V. Vaughan <gary@gnu.org>

14020 non-truncating sed or gsed program in PATH.

14025 2004-01-15 Paul Eggert <eggert@twinsun.com>
14027 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Try -std, not -std1, since
14028 -std1 disables some useful extensions on Tru64. Problem reported
14029 by N. Lichtmaier in

14032 2004-01-14 Paul Eggert <eggert@twinsun.com>
14034 * doc/autoconf.texi (Programming in M4sh): Document that
14035 AS_MKDIR_P succeeds if the destination is a symbolic link
14036 to an existing directory.
14037 (Limitations of Usual Tools): Note that mkdir -p might not
14038 succeed on symlinks to directories.
14040 2004-01-13 Paul Hilfinger <hilfinger@CS.Berkeley.EDU>
14042 * lib/autoconf/autoupdate.m4 (AU_DEFUN): Grammar fix in comment.
14043 * bin/autoheader.in: Grammar fix in message.
14044 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P):
14045 Test for dir before calling mkdir -p. (trivial changes)

14052 2004-01-10 Jim Meyering <jim@meyering.net>

14056 2004-01-09 Paul Eggert <eggert@twinsun.com>
14058 * lib/autoconf/general.m4: Fix bug: AC_CHECK_SIZEOF evokes a warning
14059 with `autoconf -Wall,error'. Bug reported by Eric Blake in:
14060 http://mail.gnu.org/archive/html/autoconf-patches/2004-01/msg00000.html
14061 (_AC_COMPUTE_INT_COMPILE): Invoke _AC_COMPILE_IFELSE, not
14062 AC_COMPILE_IFELSE, since we now assume our caller invokes
14063 AC_LANG_COMPILER_REQUIRE, for symmetry with _AC_COMPUTE_INT_RUN.
14064 (_AC_COMPUTE_INT_RUN): Likewise, for _AC_RUN_IFELSE instead
14065 of AC_RUN_IFELSE; this avoids the warning mentioned above.
14066 (_AC_COMPUTE_INT): Invoke AC_LANG_COMPILER_REQUIRE.
14068 2004-01-07 Paul Eggert <eggert@twinsun.com>
14070 * lib/autoconf/general.m4 (_AC_LIBOBJS_NORMALIZE): Avoid \$ inside
14071 `"'...'"`, as it's confusing (and I suspect it may not work on
14072 some platforms). The code was incorrect anyway, as it assumed
14073 that \$ evaluated to itself in that context. Reported by
14074 Alexandre Duret-Lutz.
14076 2004-01-07 Alexandre Duret-Lutz <adl@gnu.org>
14078 * lib/autom4te.in (Automake-preselections): Preselect AC_LIBTOOL_TAGS
14079 and _LT_AC_TAGCONFIG.

14106 * lib/autoconf/general.m4 (AC_ARG_PROGRAM):
14107 Use "rm -f" to remove conftest.sed, not plain "rm".
14108 Bug reported by David Relson in
14109 <http://mail.gnu.org/archive/html/autoconf/2004-01/msg00011.html>.
14111 * Makefile.am (autom4te-update):
14112 Replace "rm -rf" and "rm -fr" with "rm -f -r", as POSIX requires.

14128 * doc/autoconf.texi (Limitations of Usual Tools): Mention that cc
14129 -c -o might not work. From a suggestion by Kevin Ryde.
14130 (C Compiler, Generating Sources, Limitations
14131 of Usual Tools, Limitations of Make, Making testsuite Scripts):
14132 Don't put '-o' after non-options, as POSIX doesn't allow this.
14133 Mention that cc's name might be gcc or c89 or whatever.
14135 2004-01-04 Kevin Ryde <user42@zip.com.au>
14137 * doc/autoconf.texi: Add various further index entries.

14141 * bin/autoreconf.in (autoreconf_current_directory):
14142 Fix typo: mkdir without umask arg.
14144 2003-12-27 Alexandre Duret-Lutz <adl@gnu.org>
14146 * doc/autoconf.texi (Limitations of Make) <Automatic rule rewriting>:
14147 Documents OSF1/Tru64 make behavior. Replace `VPATH = ../src' by

14149 explanation clearer.

14160 * tests/atlocal.in: Store the result here.
14161 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Extracted from

14163 of explicitly testing.
14164 (AT_CHECK_PERL_SYNTAX): Moved from tools.at.
14165 (AT_CHECK_AUTOCONF): Test for the configure script syntax.
14166 * tests/tools.at (Syntax of the shell scripts): Simplify

14434 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Omit quoted

14460 cache variable instead of $G77 to decide whether to include -O2,

14471 arguments so that it can be used with syntax identical to

14473 remove/deprecate the DIALECT optional argument in the future if it
14474 proves troublesome.
14475 (AC_FC_FREEFORM): Exit 77 upon failure to fix test suite for

14547 * lib/autoconf/status.m4 (_AC_OUTPUT_COMMANDS): Make sure the
14548 directory for AC_CONFIG_COMMANDS' first argument exists.
14549 This makes valid the invocation of _AC_SRCPATH that follows.
14550 Reported by Eric Sunshine.

14574 The test suite are sometimes assigning timings incorrectly.
14575 Reported by Henk Krus.
14576 Diagnosed by Nicolas Joly.
14578 * lib/autotest/general.m4 (AT_CLEANUP): Rename AT_help as
14580 Instead of making AT_help a sequence of assignments to grow

14582 $at_help_all, and make a single assignment in...
14584 (at_times_skip): Flip the meaning and rename as...
14585 (at_times_p): this.

14598 executables, not bin/ executables! Otherwise all the magic needed
14599 to find non installed files is turned off. This caused a failure
14600 of test 40 and 41 that ran aclocal 1.8 which in turn ran autom4te
14601 as found in its environment (sent by tests/autoreconf): pointing
14602 to bin/autom4te that could not find its files.
14603 * tests/mktests.sh: Force the replacement of generated files, for
14604 the sake of "mv" program that are interactive when overwriting a

14695 2003-09-04 Akim Demaille <akim@epita.fr>
14697 * tests/mktests.sh (ac_exclude_list): Add AC_FC_FUNC.
14699 2003-09-02 Steven G. Johnson <stevenj@alum.mit.edu>
14701 Add support for newer Fortran dialects. The F77 interface is
14702 unchanged, and continues to support Fortran 77. New FC macros
14703 correspond to all the old F77 macros, with output variables FC,
14704 FCFLAGS, and FCLIBS. AC_PROG_FC defaults to picking the newest
14705 available dialect, but older dialects can be specified. There are
14706 new macros AC_FC_SRCEXT to set the source extension, and
14707 AC_FC_FREEFORM to accept free-form source files.
14709 * lib/autoconf/c.m4 (_AC_LANG_PREFIX(C), _AC_LANG_PREFIX(C++)):
14711 (AC_LANG_PROGRAM(C)): Invoke _AC_LANG_PROGRAM_C_FC_HOOKS if defined.

14825 2003-08-21 Akim Demaille <akim@epita.fr>
14827 * bin/autoheader.in (&parse_args): Use &parse_warnings and

14830 * bin/autoscan.in: Use Autom4te::ChannelDefs.
14831 * lib/Autom4te/General.pm: Don't export error: you don't own it.
14833 2003-08-21 Akim Demaille <akim@epita.fr>
14835 First stab at preserving warnings between calls to autom4te,
14836 including when the cache is used.
14838 There are still several issues: (i) there are too many runs of m4
14839 (one for include, one for warnings, and some more), (ii) warnings
14840 spreading on several lines are not handled gracefully, (iii) the
14841 code meant to have the call stack display for errors does not work
14842 (its handling should move from m4 to autom4te).
14844 * bin/autom4te.in Autom4te::Channels, Autom4te::ChannelDefs):
14846 (@preselect): Add m4_warn.
14847 ($exit_status): Remove, use $exit_code.
14848 ($help): Use Autom4te::ChannelDefs::usage.
14849 (&handle_m4): No longer define the m4_warnings.
14850 At each run, extract and report the warnings.
14851 Always cache the result, including if the exit status is on
14852 failure, since if nothing changes, we should result in the same
14853 failure, hence we can use the cache.
14854 * lib/m4sugar/m4sugar.m4 (m4_warning_ifelse, _m4_warning_ifelse)
14855 (_m4_warning_error_ifelse, __m4_warning_error_ifelse, _m4_warn):
14857 (m4_warn): Redefine as a do-nothing: it is its invocation that
14858 matters, as warnings are now reported via traces.
14859 * lib/autoconf/general.m4 (AC_DIAGNOSE): Don't make it a copy of
14860 the contents of m4_warn: make it _call_ m4_warn, so that tracing
14861 the latter reveals calls to the former.
14865 * tests/m4sugar.at (m4@&t@_warn): Use existing warning categories.
14867 2003-08-21 Akim Demaille <akim@epita.fr>

14878 (&usage): Return a string, not a side effect.
14879 (cross): New warning category.

14885 ($configure_ac): Remove.
14886 * lib/Autom4te/General.pm (&find_configure_ac, &canonfile)
14887 (&catfile): Remove.
14888 * bin/autoheader.in, bin/autoreconf.in, bin/autoupdate.in,
14889 * bin/autoscan.in: Adjust.
14891 2003-08-20 Akim Demaille <akim@epita.fr>
14893 * bin/autoheader.in: Remove duplicate 'use Autom4te::FileUtils'.
14894 Reported by Alexandre Duret-Lutz.
14896 2003-08-20 Akim Demaille <akim@epita.fr>
14898 * bin/autoupdate.in, bin/autoheader.in, bin/autoreconf.in,
14899 * bin/autom4te: Adjust.
14900 In particular, be Autoconf tools are really silent when properly
14901 working, bind the verbosity of the 'note' channel to $verbose.
14902 * lib/Autom4te/General.pm (&find_file, &mtime, &update_file)
14903 (&xsystem, &contents): Remove, since they are exported by...
14904 * lib/Autom4te/FileUtils.pm: this.

14907 * lib/Autom4te/FileUtils.pm: here.

15026 * lib/autotest/general.m4 (AT_INIT): Report a single config.log,
15027 not all of them. This fixes 1. the fact that when testing
15028 Autoconf there are many many config.log, 2. the incorrect use of
15029 top_srcdir to find config.log.
15030 Don't mix the detailed output of failed test with the summary of
15031 failures. Rather, append detailed log afterwards.
15033 2003-06-23 Akim Demaille <akim@epita.fr>

15160 as that's closer to how it'll be used.
15162 2003-05-23 Akim Demaille <akim@epita.fr>
15164 * doc/autoconf.texi (Header Portability): ucred.h.
15167 2003-05-22 Paolo Bonzini <bonzini@gnu.org>
15169 Overhaul Autotest's logging: generate separate log files
15170 in testsuite.dir/NNN/testsuite.log, and append them to
15171 testsuite.log instead of re-running the test verbosely.
15173 * lib/autotest/general.m4 (AT_INIT): Use a single redirected
15174 file descriptor, write 0 to at_status_file instead of setting
15175 at_status=0, initialize some new variables (at_status_file,
15176 at_group_log, at_suite_log, at_tee_pipe). Remove the cruft
15177 to rerun the tests, instead append the at_group_log to the
15178 at_suite_log when a test fails.
15179 (AT_SETUP): pipe the test case's output into at_tee_pipe,
15180 with the AS_MESSAGE_LOG_FD redirected to stdout.
15181 (AT_CLEANUP): save the output status in $at_status_file
15182 and restore it, redirect the AS_MESSAGE_LOG_FD back to
15183 its original place.
15184 (AT_CHECK): since tests are run with a redirected stdout,
15185 and used to be re-run in verbose mode, turn some $at_verbose
15186 into echo, and don't redirect the output of testing stdout
15189 * lib/autotest/autoconf.texi (testsuite Scripts): Update

15310 2003-05-06 Akim Demaille <akim@epita.fr>
15312 Don't try to be smart with aclocal 1.8+ because (i) aclocal no
15313 longer updates aclocal.m4 if useless, (ii) if a file m4_included
15314 by aclocal.m4 is changed it might require the importing of another
15315 m4 extension file, i.e., aclocal must be run.

15334 * lib/autotest/general.m4 (AT_KEYWORDS): Don't use a comma as the

15336 (AT_CLEANUP): Add `;' to end of at_help_all.
15337 (AT_INIT): Allow --keywords to be specified more than once. When
15338 grepping $at_help_all for keywords, use the field and keyword

15344 * doc/autoconf.texi: Make the dir entries in the autoconf manual
15345 align better with others. I also made some of the individual
15346 entries on one line, for brevity and to make it easier for me to
15347 sort my dir-example file in the Texinfo distribution :).

15588 _AC_PROG_PREPROC_WORKS_IFELSE): Use <limits.h> if __STDC__ is
15589 defined, to support freestanding compilers. This should fix the
15590 bug reported by Momchil Velkov in

15593 * doc/autoconf.texi (Obsolete Macros): Fix typos (insert empty
15594 arg, AC_DEFINE -> AC_DEFINE_UNQUOTED) in documentation for

15629 * Makefile.maint: Sync with Bison, i.e.:
15630 (po-check): Scan .l and .y files instead of the
15631 .c and the .h files that they generate. This fixes the bug
15632 reported by Tim Van Holder in:

15650 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Initialize f=$1 rather
15651 than assigning in main, to avoid HP cc +O3 optimizing it away.
15653 2002-11-12 Peter Eisentraut <peter_e@gmx.net>
15655 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Add -q
15656 option. Process --recheck after parsing all options. Pass -q
15657 option to configure on --recheck.
15658 (AC_OUTPUT): Pass -q from configure to config.status.
15659 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Strip -q from
15660 arguments to record.
15661 * doc/autoconf.texi (config.status Invocation): Document
15662 config.status -q option.
15664 2002-11-07 Alexandre Duret-Lutz <adl@gnu.org>
15666 * bin/autoscan.in (scan_file): Scan Makefile.am too. Ignore
15667 Makefile.in if Makefile.am exists.
15668 (output): Strip `.am' from Makefiles. Don't
15669 output AC_CONFIG_FILES if no Makefiles were found.

15689 Reported by Ezra Peisach.
15691 2002-11-05 Akim Demaille <akim@epita.fr>
15693 * lib/autoconf/autoheader.m4 (_AH_TEMPLATE_OLD, _AH_VERBATIM_OLD):
15695 We _have_ to stop using the old compatibility scheme that tried to
15696 avoid useless backslashes because Libtool 1.4.3 contains a
15697 AC_DEFINE([error_t], [int],
15698 [Define to a type to use for \`error_t' if it is not
15699 otherwise available.])
15700 We _have_ to quote the single quote and backslashes with \. The
15701 old compatibility scheme saw that ` was backslashed, and therefore
15702 did not quote the single quote. Hence before this patch, Autoconf
15703 was not compatible with Libtool.

15727 * doc/autoconf.texi (autoreconf Invocation): Adjust.

15748 `$(MAKE)' instead of '${MAKE}' to emphasize that we refer to the
15749 Make variable, not a shell variable.
15750 Suggested by Bruno Haible.

16146 * tests/torture.at (AC_ARG_VAR): Have configure report the value
16149 2002-10-11 Akim Demaille <akim@epita.fr>
16151 * lib/m4sugar/m4sh.m4 (_AS_PATH_SEPARATOR_PREPARE): Use $$ in the
16152 file name to enable parallel executions.
16153 From Sam Varshavchik.
16155 2002-10-08 Akim Demaille <akim@epita.fr>
16157 * bin/autoreconf.in (&autoreconf): Run autopoint before the first
16158 aclocal invocation, as Gettext macros might not be visible to
16160 Instead of blindly running autopoint, scan configure.ac (not the
16161 traces) for AM_GNU_GETTEXT_VERSION uses, as autopoint does.
16162 Reported by Paul D. Smith.
16164 2002-10-08 Paul Eggert <eggert@twinsun.com>
16166 Work around problems found when POSIXLY_CORRECT=1 is set.
16167 None of this seems to have anything to do with POSIX, really,
16168 but it's how Perl getopt works.
16169 * bin/autom4te.in (parse_args): Configure GetOpt with
16171 * doc/autoconf.texi (Invoking autom4te):
16172 --warning -> --warnings.
16173 * lib/autom4te.in: --warning -> --warnings.
16175 2002-09-28 Akim Demaille <akim@epita.fr>
16177 * doc/autoconf.texi (autom4te.cache): New section.
16179 2002-09-28 Akim Demaille <akim@epita.fr>
16181 * lib/autom4te.in (Autoscan-preselections, Autoreconf-preselections)
16182 (Automake-preselections): Update.
16183 * bin/autoreconf.in, bin/autoheader.in: Comment changes.
16185 2002-09-28 Akim Demaille <akim@epita.fr>
16187 * lib/autoscan/autoscan.pre: Move all the remaining rules to...
16188 * lib/autoconf/c.m4, lib/autoconf/functions.m4,
16189 * lib/autoconf/headers.m4, lib/autoconf/libs.m4,
16190 * lib/autoconf/specific.m4, lib/autoconf/types.m4: here.
16192 2002-09-28 Akim Demaille <akim@epita.fr>
16194 * tests/torture.at (Configuring subdirectories): Be robust to
16195 users who use config.site to require for a cache: in this case,
16196 the two last configure runs, using two different sets of
16197 arguments, trigger a legitimate error.
16199 2002-09-28 Akim Demaille <akim@epita.fr>
16201 * tests/m4sh.at (Functions Support, Functions and return Support):
16204 2002-09-28 Akim Demaille <akim@epita.fr>
16206 * bin/Makefile.am (ETAGS_SH, ETAGS_PERL): Update: ifnames and
16207 autoheader are Perl programs.
16208 (autoconf, autoheader, autoreconf, autoupdate, ifnames, autoscan)
16209 (autom4te): Specify that the sources are in the $srcdir.
16210 * doc/autoconf.texi (Installation Directory Variables): Adjust.
16212 2002-09-28 Akim Demaille <akim@epita.fr>

16215 (tm_zone): Move their rules to...
16216 * lib/autoconf/types.m4: here, using AN_ macros.
16217 * lib/autoscan/autoscan.pre (AWK, BISON, INSTALL, LEX, LN, MAKE)
16218 (RANLIB, YACC, awk, bison, byacc, flex, gawk, install, lex, ln)
16219 (make, mawk, nawk, ranlib, yacc): Similarly, move to...
16220 * lib/autoconf/programs.m4: here.
16221 * lib/freeze.mk (ETAGS_FOR_M4, ETAGS_FOR_M4SUGAR)
16222 (ETAGS_FOR_AUTOCONF): New.
16225 2002-09-28 Akim Demaille <akim@epita.fr>
16227 * lib/autoconf/autoscan.m4: New file.
16228 * lib/autoconf/autoconf.m4: Include it.
16229 * lib/autoconf/functions.m4: Use AN_FUNCTION for all the functions
16230 that were listed in the original autoscan.list.
16231 * lib/autoconf/headers.m4: Similarly with headers.
16232 * lib/freeze.mk (autoconf_m4f_dependencies): Add autoscan.m4.
16233 (.m4.m4f): Don't pass --prepend-include, since that's done by
16234 tests/autom4te itself.
16235 * lib/autoscan/Makefile.am: Include freeze.mk.
16236 (autoscan.list): New target --this file is no longer a source.
16237 (autoscan.pre): New file.
16239 2002-09-28 Akim Demaille <akim@epita.fr>
16241 * bin/autoscan.in (@kinds): Make them singular.
16243 (&init_tables): When --debug, report the list of rules to ease
16244 tracking changes in autoscan.list.
16245 * lib/autoscan/autoscan.list (function): Strip comments, sort.
16247 2002-09-28 Akim Demaille <akim@epita.fr>
16249 * lib/autoscan/functions, lib/autoscan/headers,
16250 * lib/autoscan/identifiers, lib/autoscan/makevars,
16251 * lib/autoscan/programs: Merge into...
16252 * lib/autoscan/autoscan.list: this.
16253 * bin/autoscan.in (&init_tables): Adjust.
16255 2002-09-28 Akim Demaille <akim@epita.fr>
16257 * lib/autoscan/functions, lib/autoscan/headers,
16258 * lib/autoscan/identifiers, lib/autoscan/makevars,
16259 * lib/autoscan/programs: Make the `kind' explicit, i.e., each
16260 `functions' line is now prefixed with `function:'.
16261 * bin/autoscan.in (&init_tables): Adjust.
16263 2002-09-28 Akim Demaille <akim@epita.fr>
16265 From now on, autoscan files must always map a macro name to a
16266 word: there is no `default' macro for autoscan.
16268 * bin/autoscan.in (&init_tables): Reject entries with no macro at
16270 * lib/autoscan/functions, lib/autoscan/headers: Make the macro
16273 2002-09-28 Akim Demaille <akim@epita.fr>
16275 * bin/autoscan.in (%c_keywords): Remove.
16276 (&used): Keep only track of the words we might be interested in.
16277 (&output_kind): It is no longer needed to look for non active
16280 2002-09-27 Akim Demaille <akim@epita.fr>
16282 * lib/autoconf/functions.m4 (AC_FUNC_MBRTOWC): New, stolen from
16283 jm_FUNC_MBRTOWC, by Paul Eggert, from the Coreutils 4.5.1.
16284 * lib/autoscan/functions: Adjust.
16285 * doc/autoconf.texi (Particular Functions): Adjust.
16287 2002-09-27 Akim Demaille <akim@epita.fr>
16289 * doc/autoconf.texi (Limitations of Usual Tools): Some about mv
16291 Thanks to Bill Moseley and Paul Eggert.
16292 * lib/m4sugar/m4sh.m4 (AS_TMPDIR): $2 is the directory into which
16293 the tmpdir must be created.
16294 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Have the tmp
16295 dir be in the build tree, instead of $TMPDIR.
16297 2002-09-27 Akim Demaille <akim@epita.fr>
16299 * bin/autoscan.in: Improve the comments.
16300 (&parse_args): Drop obsolete undocumented options.
16301 (&output_kind): Output warnings.
16302 * lib/autoscan/functions: (dcgettext): Now trigger AM_GNU_GETTEXT.
16303 (getwd): Trigger a warning.
16305 2002-09-26 Akim Demaille <akim@epita.fr>
16307 * bin/autoreconf.in: Clarify that -s is meaningless without -i.
16308 Reported by Ralf Corsepius.
16309 * doc/autoconf.texi (autoreconf Invocation): Likewise.
16311 2002-09-26 Akim Demaille <akim@epita.fr>
16313 Single suffix rules and seperated dependencies are not portable.
16315 * doc/autoconf.texi (Installation Directory Variables): Update.
16316 (Limitations of Make): Some about `Single Suffix Rules and
16317 Separated Dependencies'.
16318 * bin/Makefile.am (autoconf, autoheader, autoreconf, autoupdate)
16319 (ifnames, autoscan, autom4te): Un-factor into several rules.
16321 2002-09-25 Paul Eggert <eggert@twinsun.com>
16323 * BUGS (Interoperability bugs): New section. Mention libtool
16324 1.4.2, configure.ac, and AC_CONFIG_AUX_DIR interoperability bug.
16326 2002-09-24 Paul Eggert <eggert@twinsun.com>
16328 Fix a portability bug reported by Alexandre Duret-Lutz: Solaris 8
16329 make handles suffix-rules differently from GNU make.
16331 * bin/Makefile.am (SUFFIXES, .in): Remove.
16332 (autoconf autoheader autoreconf autoupdate ifnames autoscan autom4te):
16333 Move the body of the old .in rule here.
16335 2002-09-16 Akim Demaille <akim@epita.fr>
16337 i960 compilers create `b.out' files by default.
16338 Reported by Ralf Corsepius.
16340 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT): Remove b.out files.
16341 (_AC_COMPILER_EXEEXT_DEFAULT): Adjust to b.out.
16343 2002-09-13 Paul Eggert <eggert@twinsun.com>
16345 * doc/autoconf.texi (Particular Headers): Remove obsolete
16346 reference to `struct timezone' in the description of
16349 2002-09-13 Akim Demaille <akim@epita.fr>
16353 * config/config.sub, config/config.guess: Update.
16354 * Makefile.maint: Update from bits of the Coreutils 4.5.1.
16355 * Makefile.am: Adjust.
16357 2002-09-13 Akim Demaille <akim@epita.fr>
16359 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Suggest
16360 reading config.log when the compiler is rejected.
16361 Suggested by Guido Draheim.
16363 2002-09-13 Akim Demaille <akim@epita.fr>
16365 * bin/autoreconf.in: Don't use Cwd::chdir, since in its internals
16366 (chdir_init) might hang when stat'ing mounted directories.
16367 Reported by Vance Shipley.
16369 2002-09-12 Akim Demaille <akim@epita.fr>
16371 * bin/autoscan.in (&parse_args): Pass a reference to the lists, not
16374 2002-09-12 Akim Demaille <akim@epita.fr>
16376 * doc/autoconf.texi (Defining Symbols): Present two different
16377 prototypes for AC_DEFINE and AC_DEFINE_UNQUOTED to emphasize the
16378 difference between 1 argument calls, and 2-3 argument calls.
16380 2002-09-12 Peter Eisentraut <peter_e@gmx.net>
16382 * doc/autoconf.texi: Review grammar and punctuation.
16384 2002-09-11 Paul Eggert <eggert@twinsun.com>
16386 * doc/autoconf.texi: Fix minor formatting, spelling, and
16388 (Defining Symbols): Explain that AC_DEFINE(var) defaults to 1, but
16389 AC_DEFINE(var,,description) does not; and the AC_DEFINE(var) case
16392 2002-09-11 Akim Demaille <akim@epita.fr>
16394 * doc/autoconf.texi (Questions): Rename as...
16396 (Defining Directories): New.
16398 2002-09-09 Akim Demaille <akim@epita.fr>
16400 * doc/autoconf.texi (Making testsuite Scripts): Update.
16401 Suggested by Nishio Futoshi.
16403 2002-09-09 Koji Arai <JCA02266@nifty.ne.jp>
16405 * doc/autoconf.texi (Making testsuite Scripts): Use `@@' where a
16406 plain `@' is wanted.
16408 2002-09-09 Akim Demaille <akim@epita.fr>
16410 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Keep the
16411 `duplicates', since the algorithm was too naive and could keep
16412 `--prefix=1 --prefix=2 --prefix=1' as `--prefix=1 --prefix=2', and
16413 keep `--prefix foo --prefix bar' as `--prefix foo bar'.
16414 Reported by Ralf Corsepius.
16415 * tests/torture.at (Configuring subdirectories): Exercise these
16418 2002-09-09 Akim Demaille <akim@epita.fr>
16420 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Use $srcdir when
16421 looking for a replacement file.
16422 * lib/autoconf/general.m4 (AC_CHECK_DECLS): Check that the
16423 directory is relative.
16424 * doc/autoconf.texi (Generic Functions): Clarify the replacement
16425 directory definition.
16426 Reported by Andreas Schwab and Jim Meyering.
16428 2002-09-06 Akim Demaille <akim@epita.fr>
16430 * doc/autoconf.texi (Setting Output Variables): Clarify what
16431 precious variables are.
16432 Suggested by Pontus Skoeld.
16434 2002-09-05 Akim Demaille <akim@epita.fr>
16436 * bin/Makefile.am (autoconf, autoheader, autoreconf, autoupdate)
16437 (ifnames, autoscan, autom4te): Since we don't only depend on
16438 configure.ac variables (such as VERSION etc.), but also on prefix
16439 and so forth, depend on Makefile, not configure.ac.
16440 Reported by Alexandre Duret-Lutz.
16441 * doc/autoconf.texi (Installation Directory Variables): Adjust.
16443 2002-09-05 Kevin Ryde <user42@zip.com.au>
16445 * doc/autoconf.texi (Limitations of Make): HP-UX trailing backslashes
16446 doesn't seem to be confined to ia64, just say "some versions".
16448 2002-09-04 Akim Demaille <akim@epita.fr>
16450 * Makefile.am, doc/Makefile.am: Remove pdf targets, handled by
16452 * Makefile.am (maintainer-clean-local): Remove.
16453 (MAINTAINERCLEANFILES): Remove COPYING.
16455 2002-09-03 Paul Eggert <eggert@twinsun.com>
16457 * doc/autoconf.texi (Configuration Commands): Remove obsolete
16458 example for AC_CONFIG_COMMANDS_PRE. Problem reported by Marcus
16461 2002-09-03 Akim Demaille <akim@epita.fr>
16463 * configure.ac: Bump to 2.53d.
16464 * Makefile.am (AUTOMAKE_OPTIONS): Require 1.6c, i.e., CVS Automake
16465 as of today, on Automake's team suggestion.
16467 2002-09-03 Akim Demaille <akim@epita.fr>
16471 2002-09-02 Akim Demaille <akim@epita.fr>
16473 * bin/autom4te.in (parse_args): Don't honor AUTOM4TE_PATH and
16475 * configure.ac: Disable SITE_MACRO_DIR.
16477 2002-09-02 Jim Meyering <meyering@lucent.com>
16479 * doc/autoconf.texi (AC_SYS_POSIX_TERMIOS): Reflect renaming: s/am/ac/,
16480 i.e., change am_cv_sys_posix_termios to ac_cv_sys_posix_termios.
16481 Also, tweak grammar: s/make sure to/be sure to/.
16483 2002-09-02 Paul Eggert <eggert@twinsun.com>
16485 * doc/autoconf.texi (Limitations of Builtins): Explain why logical
16486 directory names are generally preferable to physical names.
16488 2002-09-02 Akim Demaille <akim@epita.fr>
16490 * lib/Autom4te/General.pm (&update_file): s/die/error/.
16491 Reported by Raja R. Harinath.
16492 * bin/autoheader.in, bin/autoreconf.in, bin/autoscan.in,
16493 * bin/autoupdate.in: Use error instead of die.
16495 2002-09-01 Paul Eggert <eggert@twinsun.com>
16497 * tests/mktests.sh (ac_exclude_egrep, au_exclude_egrep): Use
16498 ordinary shell concatenation rather than echo+tr+sed command that
16499 runs afoul of a long-line-related sed bug in Solaris 8.
16501 * bin/autoheader.in (parse_args): --warning -> --warnings.
16503 * bin/autoconf.as: Work even if "ls" outputs "FOO not found" to
16504 stdout, as traditional "ls" does.
16505 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT,
16506 _AC_COMPILER_EXEEXT_O): Likewise.
16507 * doc/autoconf.texi (Limitations of Usual Tools): Add "ls".
16509 * bin/autoconf.as: Add --prepend-include option. This patch was
16510 applied to bin/autoconf.in in the 2002-07-17 patch by Mark D. Roth,
16511 but bin/autoconf.in is generated automatically from bin/autoconf.as.
16513 * bin/autoconf.in, configure: Regenerate.
16515 * doc/autoconf.texi (Special Shell Variables): Mention
16516 ENV, MAIL, MAILPATH, PS1, PS2, PS4. Index PWD.
16518 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Unset ENV, MAIL,
16519 MAILPATH and set PS1, PS2, PS4 to default values, to work
16520 around bug in pre-3.0 UWIN ksh reported by Bruce Lilly.
16521 For LC_ALL etc, first try to set to "C" as POSIX requires and as
16522 the Autoconf documentation specifies; fall back to "unset" only if
16523 this fails. Use a shell for-loop for this rather than an m4 loop,
16524 to shorten the output script.
16526 2002-08-30 Paul Eggert <eggert@twinsun.com>
16528 * doc/autoconf.texi (Special Shell Variables): Mention POSIX
16529 1003.1-2001's requirements for CDPATH. Give a simpler workaround
16530 for the CDPATH problem. Document PWD.
16531 (Limitations of Builtins): Document the problem that "cd $foo" and
16532 "ls $foo" may refer to different directories in shells conforming
16533 to POSIX 1003.1-2001. Use PS1 rather than CDPATH for "unset"
16534 example, since the old example is now out of date.
16536 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Reject FOO if "cd
16537 FOO" and "ls FOO" talk about different directories; this catches
16538 problems when POSIX 1003.1-2001 "cd" fails due to symlink
16541 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Use AS_UNSET instead
16542 of rolling our own unset.
16543 (_AS_PREPARE): $as_unset CDPATH instead of AS_UNSETting it, since
16544 in practice we needn't worry about CDPATH if unset doesn't work.
16546 * Makefile.in, aclocal.m4, bin/Makefile.in,
16547 config/Makefile.in, doc/Makefile.in, lib/Makefile.in,
16548 lib/Autom4te/Makefile.in, lib/autoconf/Makefile.in,
16549 lib/autoscan/Makefile.in, lib/autotest/Makefile.in,
16550 lib/emacs/Makefile.in, lib/m4sugar/Makefile.in, man/Makefile.in,
16551 tests/Makefile.in: Regenerate with Automake 1.6.3.
16553 * config/config.guess, config/config.sub, config/mkinstalldirs:
16556 * configure: Regenerate with self.
16558 2002-08-30 Kevin Ryde <user42@zip.com.au>
16560 * doc/autoconf.texi (Limitations of Usual Tools): Notes on "cc"
16563 2002-08-29 Rainer Orth <ro@TechFak.Uni-Bielefeld.DE>
16565 * bin/autom4te.in (Request::load): Correctly test for "do" read
16568 2002-08-29 Akim Demaille <akim@epita.fr>
16570 * lib/Autom4te/General.pm (&xqx): New.
16571 (&xsystem): Use WIFEXITED and WEXITSTATUS instead of decoding $? by
16572 hand, which is not portable.
16574 * bin/autom4te.in: Use them.
16575 Use &error instead of die.
16576 * tests/m4sugar.at (m4_warn, m4_require: circular dependencies):
16579 2002-08-17 Paul Eggert <eggert@twinsun.com>
16581 * lib/autoconf/fortran.m4 (AC_PROG_F77): Remove fc from the
16582 default list of compilers to try, since it was long ago superseded
16583 by the ksh fc builtin. Suggested by Steven G. Johnson.
16585 2002-07-31 Alexandre Duret-Lutz <duret_g@epita.fr>
16587 * doc/autoconf.texi (Invoking autom4te): End the option table,
16588 fixing a bug introduced by the previous patch.
16589 (Limitations of Make): Add a 'target lookup' subentry in the
16590 'VPATH' entry. Rewrite all `make' occurences as `@command{make}'.
16592 2002-07-29 Mark D. Roth <roth@feep.net>
16594 * bin/autom4te.in: Remove --include-envvar and --site-macro-subdir
16595 options and use $AUTOM4TE_PATH.
16596 * doc/autoconf.texi: Remove documentation of autom4te
16597 --include-envvar and --site-macro-subdir options and document
16598 use of $AUTOM4TE_PATH.
16599 * lib/autom4te.in: Remove --include-envvar and --site-macro-subdir
16600 arguments from each language section.
16602 2002-07-29 Paul Eggert <eggert@twinsun.com>
16604 * doc/install.texi: Include copyright symbol in copyright notice.
16606 * Makefile.am (MAKEINFO): Remove; it's a user-specified macro.
16608 (AM_MAKEINFOFLAGS): New macro.
16609 * doc/Makefile.am (MAKEINFO, AM_MAKEINFOFLAGS): Likewise.
16610 * Makefile.am (INSTALL): Use the new macros.
16611 Use -o rather than --output, since "missing" does not grok --output.
16613 2002-07-25 Alexandre Duret-Lutz <duret_g@epita.fr>
16615 * doc/autoconf.texi (Limitations of Make): Escaped newlines in
16616 comments do not always work. Never trust the exit status of
16619 2002-07-24 Kevin Ryde <user42@zip.com.au>
16621 * doc/autoconf.texi (Limitations of Make, Making testsuite Scripts):
16622 Untabify, since tabs are not enjoyed by texi2dvi and makeinfo.
16624 2002-07-23 Paul Eggert <eggert@twinsun.com>
16626 * lib/m4sugar/m4sh.m4 (_AS_PATH_SEPARATOR_PREPARE):
16627 Use PATH="/nonexistent;.", not PATH=".;.", as FreeBSD ksh2002
16628 apparently treats PATH="nonexistent" as if it contained ".".
16629 Bug reported by Stefan `Sec' Zehl.
16631 2002-07-22 Alexandre Duret-Lutz <duret_g@epita.fr>

16901 2002-05-16 Paul Eggert <eggert@twinsun.com>
16903 AC_FUNC_FNMATCH now tests only for POSIX compatibility.
16904 AC_FUNC_FNMATCH_GNU also tests for GNU extensions.
16905 Both macros now accept an optional source-dir arg.
16906 New macro AC_GNU_SOURCE to define _GNU_SOURCE.
16908 * NEWS: Document this.
16909 * doc/autoconf.texi (Particular Functions, UNIX Variants): Likewise.
16911 * lib/autoconf/functions.m4 (_AC_FUNC_FNMATCH): New macro.
16912 (AC_FUNC_FNMATCH): Use it. Test only for POSIX conformance,
16913 not for GNU extensions; this undoes part of the 2000-11-03 change,
16914 reverting to 2.13-compatible behavior.

16922 * lib/autoconf/headers.m4 (AC_HEADER_TIOCGWINSZ):
16923 Don't require AC_SYS_POSIX_TERMIOS. The test is unnecessary,
16924 and it causes a 'test' syntax error if it fails.
16925 Bug reported by Stephen Gildea.
16927 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
16928 If prototypes are supported, use them to check this at compile-time,
16929 instead of trying to check it at run-time. If we must do a run-time
16930 check, assume that setvbuf is standard when cross-compiling, as
16931 nonstandard setvbuf occurs only on ancient and unlikely hosts.
16932 Bug reported by Paul D. Smith.
16934 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Add optional
16935 argument specifying location of getloadavg.c. This removes a
16936 FIXME. This idea was taken from Jim Meyering's implementation in
16938 * doc/autoconf.texi (Particular Functions): Document this.
16939 Also, mention HAVE_NLIST_H rather than NLIST_STRUCT, since
16940 that's what the code does; this fixes a bug reported by

16946 autopoint instead of gettextize.
16947 ($uses_alocal): Rename as...
16948 ($uses_aclocal): this.
16949 * doc/autoconf.texi (autoreconf Invocation): Adjust.
16950 Suggested by Bruno Haible.

16956 2002-04-29 Paul Eggert <eggert@twinsun.com>
16958 * bin/autoreconf.in (autoreconf): Don't age aclocal.m4's input
16959 files to be 1 second older; just set them to be the same time.
16960 Also, sleep 1 second after the first aclocal, to work around
16961 problems with sub-second time stamps on the input files.
16963 2002-04-29 Thien-Thi Nguyen <ttn@gnu.org>
16965 * doc/autoconf.texi: Mention "set -e -x" lossage

16972 From Christian Cornelssen.
16974 2002-04-29 Akim Demaille <akim@epita.fr>
16976 * tests/m4sh.at (LINENO): If testsuite itself is rewritten because
16977 of lack of $LINENO support, then the test will compare the $LINENO
16978 in testsuite vs. the lineno in the test file. This is wrong, of
16980 Be sure to protect it.
16981 Reported by Patrick Welche.
16983 2002-04-25 Akim Demaille <akim@epita.fr>
16985 * doc/autoconf.texi (Obsolete Macros): Typo.
16986 Reported by Vladimir Volovich.
16988 2002-04-25 Akim Demaille <akim@epita.fr>
16990 * bin/autoreconf.in (autoreconf): Don't let aclocal.m4 be older
16991 than some of the input files, hence, on the second run of aclocal,
16992 if some of its input are younger, make them older.
16993 Suggested by Paul Eggert.
16995 2002-04-25 Akim Demaille <akim@epita.fr>
16997 * doc/autoconf.texi (Limitations of Usual Tools): sed and `!'.

17003 and ac_subst_vars be sh variables containing the list of
17004 AC_SUBST_FILES'ed and AC_SUBST'ed identifiers. Output them in the
17006 (_AC_INIT_PREPARE): Use them to log them.
17007 (_AC_SUBST, _AC_SUBST_SED_PROGRAM): Remove.
17008 (AC_SUBST, AC_SUBST_FILE): Instead of buliding the
17009 _AC_SUBST_SED_PROGRAM, store the list of output files/variables in
17010 _AC_SUBST_FILES and _AC_SUBST_VARS.
17011 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Adjust.
17013 2002-04-24 Akim Demaille <akim@epita.fr>
17015 * bin/autoreconf.in (autoreconf): Run automake after autoconf and
17016 autoheader, so that automake does not complain about a missing
17017 config.h.in that was to be created.
17019 2002-04-23 Akim Demaille <akim@epita.fr>

17114 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Install the Zsh
17115 workaround for ${1+"$@"}.
17116 * doc/autoconf.texi (Shell Substitutions): Explain it.
17117 From Oliver Kiddle and Peter Stephenson.
17119 Have M4sh perform minimal shell sanitizing.
17121 * lib/m4sugar/m4sh.at (AS_SHELL_SANITIZE): Split the `_AS_PREPARE_*'
17123 (_AS_PREPARE): this new macro.
17125 (AS_INIT): Invoke AS_SHELL_SANITIZE.
17126 * tests/m4sh.at (AT_DATA_LINENO): Use _AS_PREPARE.
17128 Adjust Autoconf and Autotest.
17130 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Don't invoke
17131 AS_SHELL_SANITIZE, AS_INIT did it, but invoke AS_PREPARE.
17132 * lib/autotest/general.m4 (AT_INIT): Likewise.
17133 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
17134 Invoke _AS_PREPARE (not AS_PREPARE) in addition to
17137 Use this M4sh to generate Autoconf's shell scripts.
17139 * tests/wrapsh.as: New, precursor of wrapsh.in.
17140 * tests/Makefile.am: Include lib/freeze.mk to get the dependencies
17141 on Autotest and M4sh.
17142 ($(TESTSUITE)): Use $(autotest_m4f_dependencies).
17143 (wrapsh.in): New target.
17144 * bin/autoconf.as: New, precursor of autoconf.in.
17145 (autoconf.in): New target.
17147 2002-04-09 Alexandre Duret-Lutz <duret_g@epita.fr>
17149 * doc/autoconf.texi (Limitations of Make): Mention the issue
17150 with indented comments in rules.

17165 directories when descending in a SUBDIRS.
17166 Reported by Ezra Peisach.
17168 2002-04-04 Andreas Schwab <schwab@suse.de>
17170 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Only simplify if path
17171 contains no literal separators.
17173 2002-04-03 Akim Demaille <akim@epita.fr>
17175 * lib/autoconf/status.m4 (_AC_CONFIG_FILE, _AC_CONFIG_HEADER)
17176 (_AC_CONFIG_COMMAND, _AC_CONFIG_LINK): New.
17177 Use dnl, not the KILL diversion.
17179 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_COMMANDS)
17180 (AC_CONFIG_LINKS): here.
17182 Don't use the KILL diversion, as it kills spurious output, which
17183 results in failures being hidden.
17184 Use m4_defn where appropriate.
17185 (AC_CONFIG_IF_MEMBER): Kill the real bug: a spurious parenthesis
17186 after the second argument.
17188 * lib/autom4te.in (Autoconf, Autotest, M4sh): Don't pass --warning
17189 syntax, as it is provided by M4sugar.
17190 * tests/torture.at (Multiple AC_CONFIG_FILES): New.
17192 2002-04-03 Andreas Schwab <schwab@suse.de>
17194 * lib/m4sugar/m4sugar.m4 (m4_bmatch): Make sure m4_bregexp is not
17195 expanded if $# <= 2.

17200 2002-04-03 Akim Demaille <akim@epita.fr>

17206 (_AC_COMPILER_OBJEXT): Use them.
17207 Fixes Debian #138666.
17209 2002-04-02 Peter Eisentraut <peter_e@gmx.net>
17211 Integrate AC_PROG_CC_STDC into AC_PROG_CC.
17213 * lib/autoconf/c.m4 (AC_PROG_CC_STDC): Rename to _AC_PROG_CC_STDC.
17214 AU_DEFUN old name. Use _AC_COMPILE_IFELSE.
17215 (AC_PROG_CC): Call _AC_PROG_CC_STDC.
17216 (AC_C_INLINE): Do not require AC_PROG_CC_STDC.
17217 (AC_C_CONST): Same.
17218 (AC_C_INLINE): Same.
17219 (AC_C_PROTOTYPES): Same. Require AC_PROG_CC instead.
17220 * doc/autoconf.texi, NEWS: Document.
17221 * tests/mktests.sh (au_exclude_list): Add AC_PROG_CC_STDC and

17226 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Invoke
17227 _AS_MKDIR_P_PREPARE.
17229 2002-03-28 Kevin Ryde <user42@zip.com.au>
17231 * lib/autoconf/c.m4 (AC_C_INLINE): Test with a typedef return value,
17232 to avoid versions of HP C which don't allow that.
17234 2002-03-27 Paul Eggert <eggert@twinsun.com>
17236 * lib/m4sugar/m4sh.m4 (_AS_BASENAME_PREPARE): New macro.
17237 (AS_SHELL_SANITIZE): Invoke it.
17238 (AS_BASENAME): AS_REQUIRE it, and use $as_basename.
17240 2002-03-26 Akim Demaille <akim@epita.fr>
17242 * doc/autoconf.texi (Portable Shell): Add pointers to FAQs.
17244 2002-03-26 Akim Demaille <akim@epita.fr>
17246 * doc/autoconf.texi (Introduction): The GNATS base moved.
17248 2002-03-25 Paul Eggert <eggert@twinsun.com>
17250 * tests/m4sh.at: Don't rely on "PATH=test:$PATH test-1" working
17251 as POSIX requires, as it doesn't work with Zsh.
17252 * doc/autoconf.texi (Assignments): Document the problem.
17254 2002-03-25 Alexandre Duret-Lutz <duret_g@epita.fr>
17256 * doc/autoconf.texi (Limitations of Make): Mention more issue
17257 about VPATH, overriding of macros in sub-makes, and handling of
17260 2002-03-21 Paul Eggert <eggert@twinsun.com>
17262 * doc/autoconf.texi (Here-Documents): Mention Solaris 8 dtksh
17263 problem with here-document buffer boundaries.
17265 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Unset ENV and BASH_ENV
17266 when reinvoking the shell, to work around problems with installers
17267 who put strange things like "cd" commands in their environments.
17269 2002-03-19 Akim Demaille <akim@epita.fr>
17271 * tests/semantics.at (AC_C_BIGENDIAN): s/unknow/unknown/.
17274 2002-03-19 Akim Demaille <akim@epita.fr>
17276 * bin/autoscan.in (scan_file): Specify the location in `&used'
17280 2002-03-19 Akim Demaille <akim@epita.fr>
17282 * doc/autoconf.texi: Adjust @code/@command, @xref/@ref usage.
17283 From Nishio Futoshi.
17285 2002-03-19 Akim Demaille <akim@epita.fr>
17287 * lib/m4sugar/m4sugar.m4 (m4_define_default, m4_fst, m4_map): New.

17291 * doc/autoconf.texi (Programming in M4sh): Add AS_MKDIR_P.
17292 (Limitations of Usual Tools): Add mkdir section.
17294 * lib/m4sugar/m4sh.m4 (_AS_MKDIR_P_PREPARE): New macro.
17295 (AS_MKDIR_P): Require it. Use mkdir -p if available, falling
17296 back on AS_DIRNAME to compute prefixes otherwise; this is
17297 roughly what mkinstalldirs does. That way, we need not have
17298 our own filename disassembler. The old disassembler did not
17299 work with Solaris 8 dtksh, which is ksh Version M-12/28/93d.
17301 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP):
17302 Create at_test_all by a series of assignments,
17303 not by a single assignment of a long string. The latter causes ksh
17304 version 11/16/88g to silently misbehave on OpenServer 5.0.6a,
17305 presumably because of a buffer overrun.
17307 2002-03-14 Paul Eggert <eggert@twinsun.com>
17309 * lib/autotest/general.m4 (at_times_skip):
17310 Renamed from at_times. Now a boolean.
17311 ksh93 Version M-12/28/93d doesn't like 'x=times; $x'; it
17312 says 'times: not found'.
17314 2002-03-14 Akim Demaille <akim@epita.fr>
17316 * bin/autoreconf.in (&study_gettextize): New.
17317 (&autoreconf): Handle newest gettextize.
17318 Rerun aclocal if needed.
17319 Suggested by Andreas Schwab.
17321 2002-03-13 Akim Demaille <akim@epita.fr>

17328 Add information about stdint.h and inttypes.h from Paul Eggert.
17330 2002-03-13 Akim Demaille <akim@epita.fr>
17332 * doc/autoconf.texi (Limitations of Usual Tools): Some about `cp
17336 2002-03-12 Akim Demaille <akim@epita.fr>
17338 * lib/m4sugar/m4sh.m4 (AS_BASENAME_EXPR): AS_REQUIRE, not
17341 2002-03-11 Andreas Schwab <schwab@suse.de>
17343 * configure.ac: Explicitly check for EMACS since AM_PATH_LISPDIR
17344 does not do it if --with-lispdir is given.
17346 2002-03-08 Akim Demaille <akim@epita.fr>
17350 2002-03-08 Akim Demaille <akim@epita.fr>

17353 subdirectory should exist.
17355 2002-03-08 Akim Demaille <akim@epita.fr>
17357 * Makefile.am (AUTOMAKE_OPTIONS): 1.6.
17359 2002-03-08 Akim Demaille <akim@epita.fr>
17361 * bin/autom4te.in (&handle_m4): Do not foreach with `$_' as it
17362 aliases the actual variables, and modifications of the former
17365 2002-03-08 Akim Demaille <akim@epita.fr>
17367 * bin/autom4te.in (&handle_m4): Protect us from corrupted file
17368 because of C-c: have m4 output in tmp files, then mv them.
17370 2002-03-08 Akim Demaille <akim@epita.fr>
17372 * bin/autoconf.in, bin/autoheader.in, bin/autom4te.in,

17389 2002-03-04 Akim Demaille <akim@epita.fr>
17391 * doc/autoconf.texi (AC_LIBOBJ vs. LIBOBJS): New.
17392 * lib/autoconf/general.m4 (AC_INIT): More informative error
17393 message for LIBOBJ.
17395 2002-03-04 Akim Demaille <akim@epita.fr>
17397 * lib/freeze.mk ($(build_libdir)/m4sugar/version.m4): New, for
17400 2002-03-04 Akim Demaille <akim@epita.fr>
17402 * doc/autoconf.texi (Transforming Names): Equality between target
17403 and host is irrelevant.
17404 (Specifying Names, Canonicalizing): Remove all references to the
17405 backward compatibility hooks. Rather, collect them all into...
17406 (Hosts and Cross-Compilation): this new section.
17407 * doc/install.texi (System Type): Ditto.
17408 * lib/autoconf/general.m4 (AC_CANONICAL_HOST): Explicitly state
17409 that `--host' implies cross-compilation.
17411 2002-03-04 Akim Demaille <akim@epita.fr>
17413 * doc/autoconf.texi (Evaluation Macros): New.
17414 * lib/m4sugar/m4sugar.m4 (m4_lquote): Remove, it is totally
17416 (_m4_foreach): Define the variant with immediate evaluation so
17417 that it contains exactly the items, not an expression which
17418 evaluation is the current item.
17419 (m4_re_string, m4_re_word): Don't over quote them.
17421 2002-03-04 Akim Demaille <akim@epita.fr>
17423 Instead of having stacking `shift's evaluated at the end, let
17424 `foreach' loops immediately evaluate them.
17426 * lib/m4sugar/m4sugar.m4 (m4_quote, m4_dquote): Use $@ rather than
17427 $*. This is the n-th time I change my mind, but hopefully this is
17430 (m4_text_wrap): Use m4_foreach, which is finally correct _and_
17432 (m4_foreach_quoted, m4_car_quoted, _m4_foreach_quoted): Remove, as
17433 it was only a hack for m4_text_wrap.
17434 (m4_car2): Remove, replaced by...
17436 (_m4_foreach): Adjust.
17437 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Adjust, and use
17438 m4_bpatsubst for clarification.

17469 From Akinori Musha.
17471 2002-02-13 Alexandre Duret-Lutz <duret_g@epita.fr>

17487 2002-02-07 Akim Demaille <akim@epita.fr>
17489 Fix Autoconf PR/207:
17490 AC_PREFIX_PROGRAM fails with dashed program names
17492 * lib/autoconf/general.m4 (AC_PREFIX_PROGRAM): Just use a fresh
17493 variable when looking for the prefix program.
17494 Now it also works for shell variables.
17496 2002-02-07 Akim Demaille <akim@epita.fr>
17498 * doc/autoconf.texi (Limitations of Builtins): More about
17501 2002-02-06 Akim Demaille <akim@epita.fr>

17504 case/esac, some shells don't support it.
17505 Reported by Zack Weinberg.
17506 * tests/torture.at (AC_CONFIG_COMMANDS with empty commands): New.
17508 2002-02-06 Akim Demaille <akim@epita.fr>
17510 * lib/autotest/general.m4 (AT_INIT): When handling --keywords, be
17511 sure not to introduce newlines in at_groups.

17525 * tests/semantics.at (AC_CHECK_SIZEOF): Check non-GCC
17526 cross-compilers, too. This undoes some of the most recent change
17529 2002-02-05 Akim Demaille <akim@epita.fr>
17531 * tests/Makefile.am (check_SCRIPTS): Use it, instead of WRAPPERS,
17532 to make sure they are up to date when `check' is run.
17534 2002-02-05 Akim Demaille <akim@epita.fr>

17548 * lib/autoconf/autoconf.m4, lib/autotest/general.m4,

17551 2002-02-05 Akim Demaille <akim@epita.fr>
17553 * bin/autom4te.in (&parse_args): Implement `frozen files are
17554 optional are the sum of the previous files on the command line'.
17555 Also, pass `--reload-state=' on them, so...
17556 (handle_m4): don't.
17557 * lib/autom4te.in (Autotest, Autoconf): Rely on M4sh.
17558 (M4sh): Rely on M4sugar.
17559 (Autotest, M4sh, M4sugar): Use frozen files.
17561 2002-01-31 Akim Demaille <akim@epita.fr>
17563 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Accept $4.

17566 2002-01-30 Akim Demaille <akim@epita.fr>
17568 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Map non
17569 alphanumeric to `-' instead of `_'.
17571 2002-01-30 Akim Demaille <akim@epita.fr>
17573 * tests/semantics.at (AC_CHECK_SIZEOF): Split into two tests: one
17574 for plain code, the other for cross-compilation code. The latter
17575 is now run with GCC only.
17576 * doc/autoconf.texi (Compilers and Preprocessors): New.

17580 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Support pre-defined
17582 * doc/autoconf.texi (Initializing configure): Explain how to
17583 change AC_INIT default values.
17585 2002-01-29 Akim Demaille <akim@epita.fr>
17587 * tests/torture.at (Configuring subdirectories): Use configure.in,
17588 so that aclocal 1.4 works.
17589 Reported by Alexandre Duret-Lutz and Larry Schmitt.
17591 2002-01-28 Akim Demaille <akim@epita.fr>
17593 * doc/autoconf.texi (Writing testsuite.at): AT_CLEANUP no longer
17596 2002-01-28 Akim Demaille <akim@epita.fr>
17598 * lib/autotest/general.m4 (AT_INIT): Don't be ridiculous: adjust
17599 AUTOTEST_PATH *after* it was set.
17600 Don't put `.' in the PATH: the user should be precise and `./' if
17601 needed. In addition, given that the test suite does some `cd', if
17602 `.' is in the path, the `tested programs' sections will report
17603 programs found in the test suite's directory, while during the
17604 tests (performed in their own directory), these programs are no
17605 longer visible. In other words, the results is confusing and
17607 * tests/m4sh.at: Adjust: don't rely on `.' being in the PATH.

17652 message on invalid options.
17653 * bin/autom4te.in (parse_args): Don't use
17654 Autoconf::General::getopt with non valid options.

17673 package.m4, since is really depends upon configure.ac, not
17675 * doc/autoconf.texi (testsuite Scripts): Adjust.
17676 * tests/Makefile.am (package.m4): New.
17677 EXTRA_DIST it since its a source.
17679 2002-01-06 Akim Demaille <akim@epita.fr>
17681 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Move the AC_SUBST
17682 of PACKAGE_NAME, PACKAGE_TARNAME, PACKAGE_VERSION, PACKAGE_STRING,
17683 and PACKAGE_BUGREPORT from here...
17684 (_AC_INIT_DEFAULTS): to here, since it is unrelated to the
17686 (_AC_INIT_PREPARE): AC_DEFINE these symbols.
17687 * lib/autotest/general.m4: Use AT_PACKAGE_*, not PACKAGE_*.
17688 (AT_INIT): No longer catch `^PACKAGE_(BUGREPORT|STRING)$'.

17707 2001-12-17 Jim Meyering <meyering@lucent.com>
17709 * doc/autoconf.texi (New Macros): Tweak wording.
17711 2001-12-14 Akim Demaille <akim@epita.fr>
17713 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): We cleaning up the
17714 trailing files, don't apply `-rf' to files which might not be
17715 created by configure (core, core.*, and *.core), but just `rm -f'.
17716 Suggested by Jonathan Kamens.
17718 2001-12-14 Aaron M. Ucko <amu@alum.mit.edu>
17720 * lib/autoconf/general.m4: Avoid duplicates in `$ac_configure_args'.

17729 abs_builddir, top_buildpath to abs_top_builddir, srcpath to
17730 abs_srcdir, top_srcpath to abs_top_srcdir.
17731 (_AC_OUTPUT_FILES): Adjust.
17732 * NEWS, doc/autoconf.texi, lib/autoconf/autotest.m4,
17733 * tests/atspecific.m4, tests/autoreconf.in, tests/tools.at,
17734 * tests/wrappl.in, tests/wrapsh.in: Adjust.
17736 2001-12-12 Steven G. Johnson <stevenj@alum.mit.edu>
17738 * lib/autoconf/fortran.m4 (_AC_PROG_F77_V_OUTPUT): Fix failed

17742 2001-12-12 Kevin Ryde <user42@zip.com.au>
17744 * doc/autoconf.texi (File Descriptors): Use a clearer layout for the
17745 forbidden file descriptors table.
17747 2001-11-26 Akim Demaille <akim@epita.fr>
17749 * bin/autoscan.in (%c_keywords): Build it at top level.

17752 2001-11-26 Akim Demaille <akim@epita.fr>
17754 * bin/autoscan.in (&scan_c_file, &scan_sh_file, &scan_makefile):
17755 Remove $filepath, useless.
17756 (&scan_makefile): Don't remove the $(FOO), ${FOO} and @FOO@
17757 variables, they are really part of the tokens.
17758 Split the input line on spaces and then look for tokens.
17759 Now autoscan ceases to ask for AC_PROG_LEX for the package Bison
17760 because of `lex$U.$(OBJEXT)'.
17761 (&scan_files): Use "@list" instead of join.
17762 * doc/Makefile.am (CLEANFILES): Add *.fns.
17764 2001-11-26 Akim Demaille <akim@epita.fr>

17767 Remove, replaced by...
17768 * tests/wrappl.in: Be common for all the Perl executables.
17769 In particular autoscan and autoheader want -I.
17770 * configure.ac: Adjust.
17771 * lib/autoscan/headers: errno.h is portable.
17773 2001-11-26 Akim Demaille <akim@epita.fr>
17775 * bin/autoscan.in (used): New.
17778 2001-11-26 Akim Demaille <akim@epita.fr>
17780 * bin/autoscan.in (&scan_c_file): Better parsing of CPP
17782 (&scan_sh_file): Remove a duplicate pattern.

17789 Before, having a line containing the opening of a multi line
17790 comment made the whole line be ignored.
17792 2001-11-26 Akim Demaille <akim@epita.fr>
17794 * doc/autoconf.texi (Using an Autotest Test Suite): New.

17800 Test groups are now run two directories deeper.
17802 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Replace srcdir,
17803 top_srcdir and top_builddir with at_srcdir, at_top_srcdir and
17805 * lib/autotest/general.m4 (AT_INIT): Compute srcdir,
17806 top_srcdir, builddir and top_builddir.
17807 Use `at_*dir' relatively to the directory containing the
17808 suite, use `*dir' when relatively to the current group dir.
17810 2001-11-25 Joseph S. Myers <jsm28@cam.ac.uk>
17812 * doc/autoconf.texi, TODO, lib/autoconf/fortran.m4,
17813 lib/autoconf/functions.m4, lib/autoconf/headers.m4,
17814 tests/atgeneral.m4, tests/tools.at, tests/atspecific.m4: Fix
17817 2001-11-22 Alexandre Duret-Lutz <duret_g@epita.fr>
17819 * doc/autoconf.texi (Using System Type): Add an example of `case
17820 $host' usage so people quit using `case $target' everywhere.
17822 2001-11-22 Akim Demaille <akim@epita.fr>
17824 * doc/autoconf.texi (Installation Directory Variables): Englishoes
17825 spotted by Jim Meyering.
17827 2001-11-16 Paul Eggert <eggert@twinsun.com>
17829 This patch implements a `long double' suggestion by Oliver Kiddle.
17831 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C)): Make the array
17832 static, to catch errors if the value isn't known at compile-time
17833 and the compiler supports dynamic arrays. Change its name from
17834 `_array_' to `test_array' to avoid potential name clashes.
17835 (AC_C_LONG_DOUBLE): Make it a compile-time test, not a run-time
17836 test. Do not define HAVE_LONG_DOUBLE if `long double' is no
17837 better than double. Catch a bug in GCC 2.95.2 x86.
17838 * doc/autoconf.texi (C Compiler): Document the above.
17841 2001-11-13 Akim Demaille <akim@epita.fr>
17843 * tests/m4sh.at (LINENO): Protect from autom4te's substitution by
17845 * tests/tools.at: Don't protect dnl, AT_DATA_M4SH does.
17847 2001-11-13 Akim Demaille <akim@epita.fr>
17849 * lib/autotest/general.m4 (AT_INIT): After having run the test
17850 group, go back to the initial directory, not to at_suite_dir.
17852 2001-11-13 Akim Demaille <akim@epita.fr>
17854 * tests/atspecific.m4 (AT_DATA_M4SUGAR, AT_DATA_M4SH)
17855 (AT_DATA_AUTOCONF): Also protect @&t@ from autom4te.
17856 (AT_CHECK_AUTOCONF, AT_CHECK_AUTOHEADER): Pass no --include
17858 (AT_CHECK_CONFIGURE): Use absolute paths.
17859 (_AT_CHECK_AC_MACRO): Create aclocal.m4 with AC_STATE_SAVE in it.
17860 The problem is still the old one: there is no means in M4 (that I
17861 know about) to create a defining macro, because there is no means
17862 to create `$1' etc., therefore, the defining macro ``swallows''
17863 all the arguments meant to the defined macro.
17865 2001-11-13 Akim Demaille <akim@epita.fr>
17867 * tests/atspecific.m4 (AT_DATA_AUTOCONF): New.
17868 (AT_CONFIGURE_AC): Output the definition of AC_STATE_SAVE in
17870 * tests/aclocal.m4: Remove, as it is no longer used.
17872 2001-11-13 Akim Demaille <akim@epita.fr>
17874 * lib/autotest/general.m4: Change `tests?' into `groups?' in
17875 variable names when referring to a single test group, or to
17876 `suite' when referring to the whole test suite.
17877 `at_last_test' is removed: m4 compute at_format itself.
17878 (at_stdout, at_stder1, at_stderr): New variables.
17879 (AT_CHECK): Use them.
17881 2001-11-13 Akim Demaille <akim@epita.fr>
17883 * lib/autotest/general.m4 (AT_INIT): Be sure to put `.', relative,
17885 Create `testsuite.dir/003/run' instead of `testsuite.003'.
17886 Do it as soon as a test fails, don't wait till the end of the test
17888 Don't remove $as_me.[0-9]*, since these files no longer exist.
17890 2001-11-13 Akim Demaille <akim@epita.fr>
17892 * tests/tools.at: Use absolute paths, since we are no longer run
17895 2001-11-13 Akim Demaille <akim@epita.fr>
17897 Now that tests are running in their own private dir, there is no
17898 need to list the files to remove at the end of tests groups.
17900 * lib/autotest/general.m4 (_AT_CLEANUP_FILE, AT_CLEANUP_FILES):
17901 (AT_data_files, at_data_files): Remove.
17902 (AT_CLEANUP, AT_DATA): Simplify.
17904 Remove the group dir if !debug && !failed.
17905 * tests/atspecific.m4: Adjust.
17907 2001-11-13 Akim Demaille <akim@epita.fr>
17909 Start a new layout for Autotest: `testsuite' creates
17910 `testsuite.dir' in which the at-check-line etc. files are to be
17911 found, and `testsuite.dir/003' where the test group 3 is run.
17913 * lib/autotest/general.m4 (AT_INIT): at_tests_dir,
17914 at_check_line_file, at_format, at_test_normalized, at_group_dir
17916 Create the directories.
17917 Use absolute paths for at- files.
17918 (AT_CHECK): Adjust.
17920 2001-11-11 Michael Matz <matz@kde.org>
17922 * m4sugar.m4 (_m4_foreach): Make it linear instead quadratic.
17924 (m4_car): Properly quote arguments.
17926 2001-11-13 Akim Demaille <akim@epita.fr>
17928 * tests/aclocal.m4 (AC_STATE_SAVE): s/LIBOBJS/LIB@&t@OBJS/ to cope
17929 with stricter rules on LIBOBJS.
17931 2001-11-12 Paul Eggert <eggert@twinsun.com>
17933 * lib/autoconf/c.m4 (AC_C_PROTOTYPES): Define __PROTOTYPES too.
17934 * doc/autoconf.texi (C Compiler): AC_C_PROTOTYPES now defines
17937 2001-11-12 Akim Demaille <akim@epita.fr>
17939 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT): Use AC_CHECK_FUNCS.
17941 2001-11-12 Akim Demaille <akim@epita.fr>
17943 * lib/autoconf/c.m4, lib/autoconf/fortran.m4,
17944 * lib/autoconf/functions.m4, lib/autoconf/general.m4,
17945 * lib/autoconf/headers.m4, lib/autoconf/libs.m4,
17946 * lib/autoconf/programs.m4, lib/autoconf/specific.m4,
17947 * lib/autoconf/types.m4: When invoking AC_DEFINE and friends,
17948 specify to what the macro should be defined (typically to 1).
17950 2001-11-12 Akim Demaille <akim@epita.fr>
17952 * lib/autoconf/functions.m4 (AC_FUNC_STRTOD): AC_SUBST POW_LIB.
17955 2001-11-12 Akim Demaille <akim@epita.fr>
17957 * lib/autoconf/programs.m4 (_AC_PROG_LEX_YYTEXT_DECL): Use
17958 AC_TRY_EVAL to run $LEX, not AC_TRY_COMMAND. This validates the
17959 definition used by Automake where LEX is +/- "${missing} lex" and
17960 `missing' itself contains variables.
17962 2001-11-12 Akim Demaille <akim@epita.fr>
17964 * lib/autotest/general.m4 (AT_INIT): Push KILL at the end.
17965 Now that M4sh pushes BODY, the comments were output at the end of
17968 2001-11-08 Akim Demaille <akim@epita.fr>
17970 * bin/autoreconf.in (&autoreconf): Run aclocal before tracing, so
17971 that we can trace macros from aclocal.m4.
17972 Trace AC_PROG_LIBTOOL, not AM_PROG_LIBTOOL, since the latter is
17973 obsoleted, and redirect to the former anyway.
17974 Reported by Ralf Corsepius.
17976 2001-11-08 Akim Demaille <akim@epita.fr>
17978 * bin/autoreconf.in (&autoreconf): AC_CONFIG_SUBIDRS are to be
17979 processed only if present.
17980 * tests/torture.at (Configuring subdirectories): Use autoreconf
17981 instead of successive calls to autoconf.
17982 Add a nonexistent subdirectory to exercise the patch above.
17983 Reported by Ralf Corsepius.
17985 2001-11-08 Kevin Ryde <user42@zip.com.au>
17987 * doc/autoconf.texi (Limitations of Usual Tools): Note HP-UX cc
17988 doesn't accept .S files.
17990 2001-11-07 Akim Demaille <akim@epita.fr>

17994 (_AC_LIBOBJ): s/LIBOBJS/LIB@&t@OBJS/.
17995 * bin/autom4te.in (warn_forbidden): New.
17996 (handle_output): Use it.
17997 Read m4_pattern_forbid with messages.
17999 2001-11-05 Akim Demaille <akim@epita.fr>
18001 * bin/autom4te.in (--normalize): Remove.
18002 * lib/autom4te.in: Adjust.
18004 2001-11-05 Akim Demaille <akim@epita.fr>
18006 * tests/Makefile.am (testsuite): Rename this target as...
18007 ($(TESTSUITE)): this.
18010 2001-11-05 Alexandre Duret-Lutz <duret_g@epita.fr>
18012 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): When removing
18013 the --prefix option, also remove it's argument.
18015 2001-11-05 Akim Demaille <akim@epita.fr>
18017 * doc/autoconf.texi (testsuite Invocation): Update.
18018 (Writing testsuite.at): Update.
18020 2001-11-03 Akim Demaille <akim@epita.fr>

18024 2001-11-03 Akim Demaille <akim@epita.fr>
18026 * lib/Autom4te/General.pm: (&catfile, &canonfile)
18027 (&file_name_is_absolute): New, wrappers around routines from
18029 Use and export them.
18030 (&find_configure_ac): Optionally take a directory where to look at.
18031 * bin/autoreconf.in (&parse_args): Trim the configure.ac part of
18033 Default @ARGV to `.', not find_configure_ac.
18034 (&autoreconf): Argument is a directory.
18035 Trace AC_CONFIG_SUBDIRS and schedule the subdirs for autoreconf'ing.
18036 * doc/autoconf.texi (autoreconf Invocation): Update.
18038 2001-11-03 Akim Demaille <akim@epita.fr>
18040 * lib/Autom4te/General.pm (@export_vars, @export_subs)
18041 (@export_forward_subs): New.
18042 Add basename, dirname, and fileparse.
18044 * bin/autoreconf.in (&autoreconf): Fix call to fileparse.
18045 Don't look for aclocal flags if we already know aclocal is not
18047 Move aclocal.m4t only if it exists.
18048 Reported by Ezra Peisach.
18050 2001-11-03 Akim Demaille <akim@epita.fr>
18052 * bin/autoreconf.in (&parse_args): Work only on the configure.ac
18053 passed on command line, defaulting to ./configure.ac if present.
18054 (&maybe_autoreconf, File::Find): Remove, unused.
18055 (&autoreconf): If autoconf is not used, don't try to trace.
18057 2001-11-02 Akim Demaille <akim@epita.fr>
18059 * configure.ac: Bump to 2.52g.
18061 2001-11-02 Akim Demaille <akim@epita.fr>
18065 2001-11-02 Akim Demaille <akim@epita.fr>

18068 * config/lispdir.m4: Update from masters.
18069 * configure.ac: Bump to 2.52f.
18071 2001-11-02 Akim Demaille <akim@epita.fr>
18073 * bin/autoreconf.in (&autoreconf): Set `$aclocal_flags' to ''.
18074 Don't run aclocal when aclocal.m4 is not from aclocal.
18076 Don't run libtoolize and gettextize if --install is not given.
18078 2001-11-01 Paul Eggert <eggert@twinsun.com>
18080 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): _AS_CR_PREPARE needs to
18081 be invoked before _AS_LINENO_PREPARE.
18082 (_AS_LINENO_PREPARE): Use as_cr_digits and as_cr_alnum rather
18083 than character ranges.
18085 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Fix NLS before
18086 invoking AS_BASENAME. Set the locale variables to 'C' if
18087 possible, as POSIX requires this to get the traditional
18089 * doc/autoconf.texi (Special Shell Variables): Describe the above.
18091 2001-10-31 Paul Eggert <eggert@twinsun.com>
18093 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): Do not surround body
18094 with {}, as that triggers a bug in Bash 2.05.
18096 (_AS_LINENO_PREPARE): Use Sed rather than
18097 Awk. Fix the sed prepass to work even if there are multiple
18098 instances of $LINENO on the same line. Do not substitute for
18099 other variables like $LINENOT. Do not check file dates; such a
18100 check is unreliable on sufficiently fast machines, and removing
18101 the check makes the code simpler and more reliable. Check for
18102 output and chmod failures.
18104 * doc/autoconf.texi (Special Shell Variables): Document

18116 provided, while it is optional.
18117 * configure.ac: Adjust.

18122 lib/Autom4te/Struct.pm:
18123 Require Perl 5.005_03 instead of just 5.005, as some tests fail
18126 * doc/autoconf.texi (Special Shell Variables): Document some
18127 more LINENO gotchas, particularly with respect to the Awk+Sed hack.
18129 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): New macro.
18130 (_AS_LINENO_PREPARE): Use it instead of shell eval, since
18131 eval $LINENO is not portable in practice.

18149 * lib/autoconf/functions.m4 (AC_FUNC_STRERROR_R):
18150 Rename ac_cv_func_strerror_r_works to ac_cv_func_strerror_r_char_p,
18151 and rename HAVE_WORKING_STRERROR_R to STRERROR_R_CHAR_P, since
18152 POSIX decided to standardize on the int flavor of strerror_r.
18153 Always do char* test, as there's no reason not to.
18154 Assign to a char* var, to catch strerror_r that returns int*.
18156 * doc/autoconf.texi (Particular Functions):
18157 Document the above changes. Also, document the fact that
18158 AC_FUNC_STRERROR_R defines HAVE_DECL_STRERROR_R.

18182 * bin/autoheader.in ($localdir, $m4, $SIMPLE_BACKUP_SUFFIX):
18184 * bin/autoreconf.in (&autoreconf): Do not run gettextize when
18185 `intl' is already present, as it refuses unless --force.
18186 (&parse_args): Use -I, --include instead of the old Autoconf
18188 ($localdir, $autoconf_dir): Remove.

18213 configure.ac being studied.
18215 2001-10-18 Paul Eggert <eggert@twinsun.com>
18217 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Cast sizeof to unsigned

18224 (AS_BASENAME): Use 'basename' if that works; then try 'expr';

18228 contains white space.
18229 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR):

18286 2001-10-08 Akim Demaille <akim@epita.fr>

18607 2001-09-22 Akim Demaille <akim@epita.fr>
18609 Rely on `$LINENO' when possible instead of `__oline__'.

18612 `$LINENO' support replacement when not supported.
18613 (_AS_CR_PREPARE, _AS_TR_CPP_PREPARE, _AS_TR_SH_PREPARE): Invoke

18628 2001-09-21 Akim Demaille <akim@epita.fr>
18630 * Makefile.maint (AUTOM4TE): Neutralize autom4te.
18631 Suggested by Jim Meyering.

18651 be used instead of ':'.
18652 * lib/autotest/general.m4: Replace occurrences of ':' in
18653 AUTOTEST_PATH with $PATH_SEPARATOR at test suite startup.
18655 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>

18658 arguments. Fixed a typo.
18660 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
18662 * man/Makefile.am (.x.1): Use @PATH_SEPARATOR@, not ':' to set up
18663 $PATH. Also set AUTOM4TE_CFG, so we can process autom4te properly.
18665 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
18667 * bin/autoscan.in: Add 'exec-perl-if-not-run-by-perl'.

18674 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
18676 * lib/Autom4te/XFile.pm (open): Simplified the error message (we
18677 already have $file). Set output files to binary mode (helps avoid
18678 CR issues on DOSish systems).
18680 2001-09-19 Akim Demaille <akim@epita.fr>
18682 * lib/autotest/general.m4: Englishoes.
18683 From Tim Van Holder and Alexey Mahotkin.
18685 2001-09-18 Paul Eggert <eggert@twinsun.com>
18687 * doc/autoconf.texi (Common Shell Constructs): New node,
18688 documenting AS_DIRNAME.
18689 (Limitations of Usual Tools): Refer to it when discussing dirname.
18690 Also, update discussion of POSIX standard to reflect latest draft.
18692 * lib/autoconf/c.m4:
18693 (AC_LANG_INT_SAVE(C)): Also support negative values, down to LONG_MIN.
18695 * lib/autoconf/general.m4 (_AC_COMPUTE_INT_COMPILE):
18696 Do not pass a first argument with leading '-'
18697 to expr, by parenthesizing initial integers that might be negative.
18699 * doc/autoconf.texi (Particular Functions): AC_FUNC_GETPGRP
18700 now merely checks whether it is an error to pass an argument
18703 * lib/autoconf/functions.m4 (_AC_FUNC_GETPGRP_TEST): Remove.
18704 (AC_FUNC_GETPGRP): Don't bother with a runtime test. Just check
18705 whether it is a (compile-time) error to pass an argument to
18706 getpgrp. This simpler test supports the revised documentation,
18707 and is all that AC_FUNC_GETPGRP's users really need.
18709 2001-09-18 Akim Demaille <akim@epita.fr>
18711 * doc/autoconf.texi (Limitations of Make) <$<>: New.

18721 * tests/m4sh.at: Ensure that AS_DIRNAME handles '/', '//' and '///'
18723 Add test for AS_BASENAME.
18724 * lib/m4sugar/m4sh.m4: Fix AS_BASENAME so that it passes the previous
18725 added test. It now correctly handles /1/2/3/, returning '3' not ''.
18726 Added AS_BASENAME_SED to make the interface the same as AS_DIRNAME.
18727 * tests/base.at: Fixed the expected responses. The old ones were
18729 * lib/autoconf/general.m4: Fixed AC_PREFIX_PROGRAM, it now behaves as
18730 the documentation claims it should (and how it behaved in 2.13).
18732 2001-09-18 Akim Demaille <akim@epita.fr>
18734 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): No INIT-CMDS in
18735 the AC_CONFIG_COMMANDS invocation.
18736 This also solves the name clash problems.
18737 Don't set the package's ID.
18738 * lib/m4sugar/Makefile.am (version.m4): Revamp.
18739 No longer to be shipped.
18740 (version.in): Remove.
18741 * lib/m4sugar/m4sugar.m4, lib/autoconf/general.m4,
18742 * lib/autoconf/status.m4: Adjust.
18743 Use `m4_PACKAGE_STRING'.
18744 * lib/autotest/general.m4 (AT_INIT): N-th signature change: now
18745 the only optional argument is the name of the test suite.
18746 Expect `package.m4' to define the package signature.
18747 * lib/autom4te.in (Autotest): Add `package.m4?'.
18748 * tests/Makefile.am (package.m4): New.
18749 * tests/suite.at: ifnames is a victim.
18751 2001-09-18 Akim Demaille <akim@epita.fr>
18753 * lib/autom4te.in (Autoconf): Preselect AM_CONDITIONAL,
18754 AC_LIBSOURCE, AC_CONFIG_FILES.
18755 * lib/autotest/general.m4 (AT_INIT): Don't abort when a tested
18756 program version string doesn't match the package's.
18757 * lib/autoconf/general.m4 (AC_CACHE_VAL): Reestablish the space

18762 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):
18763 Allow expression to return any value that can fit into unsigned long

18768 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):
18769 Always include <stdio.h> and <stdlib.h>. Evaluate
18770 the expression in an extra function before these includes. Call
18771 fprintf "%d" only after ensuring the argument is of type 'int'.
18772 Reported by Wayne Chapeskie <waynec@spinnaker.com>.
18774 2001-09-17 Paul Eggert <eggert@twinsun.com>
18776 Fix bug reported by Paul Townsend on AIX 4.3.3.0 with CFLAGS=-O4
18777 or CFLAGS=-O5. In that case, the linker has a relaxed view of
18778 fatal errors, and AC_CHECK_LIB causes it to include libraries even
18779 when they don't exist.
18781 * lib/autoconf/headers.m4 (AC_HEADER_DIRENT): Use AC_SEARCH_LIBS,
18782 not AC_CHECK_LIB, so that we don't use -ldir or -lx if we don't
18785 * lib/autoconf/specific.m4 (AC_ISC_POSIX): Replace the old, crufty
18786 version with the version used by fileutils 4.1, except use
18787 AC_SEARCH_LIBS, not AC_CHECK_LIB, so that we don't use -lcposix if
18790 * doc/autoconf.texi (AC_ISC_POSIX): Describe new behavior.
18792 2001-09-13 Akim Demaille <akim@epita.fr>

18832 * lib/autotest/general.m4 (AT_INIT): Create and remove
18833 `$as_me.[0-9]+' instead of `debug-[0-9]+.sh', so that multiple
18834 test suites can cohabit.
18836 2001-09-13 Akim Demaille <akim@epita.fr>
18838 * tests/mktests.sh: Don't output banners for empty test files.

18890 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Don't pass

18893 * lib/autoconf/programs.m4 (AC_SHELL_PATH_WALK): Use PATH_SEPARATOR.

18944 2001-09-05 Akim Demaille <akim@epita.fr>
18946 Be ready to handle filenames as stupid as `dnl.at', for if even
18947 the maintainer is dumb enough to do that...
18949 * lib/autotest/general.m4 (AT_SETUP, AT_LINE): Demonstrates your
18950 excellence in M4 quotation: consider `__file__' is active.
18952 And BTW, when invoking m4, pass the --include in the right order:

19031 2001-08-31 Akim Demaille <akim@epita.fr>
19033 * man/Makefile.am (.x.1): We really have to pass
19034 autom4te_perllibdir.
19036 2001-08-31 Akim Demaille <akim@epita.fr>
19038 * lib/autotest/general.m4 (AT_INIT): Don't pass all the args to
19039 debug scripts, in particular passing explicitly listed tests to

19089 * tests/atspecific.m4 (AT_CHECK_AUTOHEADER): Now autoheader says
19090 `autoheader: `config.hin' is created'.
19091 * tests/tools.at (Syntax of the Perl scripts): Check autoheader.
19093 2001-08-31 Akim Demaille <akim@epita.fr>

19101 Map --localdir, --autoconf-dir onto it.
19102 Forward autom4te's options instead of interpreting them.

19104 There is no such envvar since the inception of autom4te.cfg.

19132 * tests/atlocal.in: Remove all the obscure envvar manipulations.
19134 * tests/atspecific.m4, tests/tools.at: Passing --localdir is
19135 indeed related to running the test suite, while passing

19137 Autoconf executables. So don't do that, leave it to...

19139 * tests/autoscan: New.
19140 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): Don't

19159 2001-08-29 Akim Demaille <akim@epita.fr>

19626 autom4te.cache (it's a directory, not a file.
19627 * Makefile.am: Ditto (but maintainer-clean-local).
19629 2001-08-15 Akim Demaille <akim@epita.fr>
19631 * bin/autom4te.in (@m4_warning): New.
19632 (&handle_m4): Use it.
19633 * tests/m4sugar.at (m4_warn): Pass `-f' to autom4te to ensure the
19634 warnings are issued at each run.
19635 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): M4sugar
19636 is in the src tree.

19705 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Handle ACTION-IF-TRUE,
19706 ACTION-IF-FALSE, and ACTION-IF-UNKNOWN.
19707 * doc/autoconf.texi (C Compiler Characteristics): Update

19713 magic values from an object file when cross-compiling.
19714 Based on code by Guido Draheim <Guido.Draheim@gmx.de>.
19716 2001-08-10 Akim Demaille <akim@epita.fr>
19718 * bin/autom4te.in (&handle_output): Don't use `grep' with side
19720 Suggested by Russ Allbery.
19722 2001-08-10 Ralf Corsepius <corsepiu@faw.uni-ulm.de>
19724 * lib/autoconf/general.m4 (_AC_OUTPUT_SUBDIRS): Propagate the
19725 current $prefix to the sub-configures.
19727 2001-08-09 Tim Van Holder <tim.van.holder@pandora.be>
19729 * lib/autoconf/lang.m4: Ignore *.xSYM when looking for an executable
19730 extension (needed on BeOS). Reported by Guido van Rossum.
19732 2001-08-09 Akim Demaille <akim@epita.fr>
19734 * bin/autom4te.in ($icache): Load it only if older than autom4te.
19736 2001-08-07 Akim Demaille <akim@epita.fr>
19738 * lib/autotest/general.m4 (AT_INIT): All the `at-*' are to be
19740 (at-setup-line): Huh? Be a variable `at_setup_line', not a file.
19741 No need to remove the files before and after the each test, before
19742 each test and at the end of the suite is enough.
19743 Display only the children `times', not the shell's.
19744 If the test failed or was skipped, at-times is not available.
19746 2001-08-07 Akim Demaille <akim@epita.fr>
19748 Always produce testsuite.log, including when there are no
19749 failures. This helps getting information on skipped tests, and
19750 duration of the tests. Err, implement the latter btw.
19752 * lib/autotest/general.m4 (AT_INIT): Set up fd 6 for the log.
19753 Dump information on the first run of each test.
19754 (AT_CLEANUP): Create `at-times' containing the duration of the
19757 2001-08-07 Akim Demaille <akim@epita.fr>
19759 The use of `dumpstat' revealed that `len' was used although it
19760 should not. m4_text_wrap was using it, but in the Autoconf world
19761 where it is legal. Hence (i) test M4sh in its own world, not
19762 Autoconf's, and (ii), ahem, fix the bug :)
19764 * lib/autotest/general.m4: Be sure the set good quotes, as tracing
19765 does not like `' instead of [].
19766 (AT_INIT): Forbid `^_?AT_'.
19767 And don't output such tokens.
19768 * tests/Makefile.am (CLEANFILES): Add `script', `script.s4g',
19769 `script.as', and `autom4te.cache'.
19770 Remove `empty' and `macro' which are no longer used.
19771 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): New.
19772 * tests/m4sugar.at: Use it.
19773 * lib/m4sugar/m4sugar.m4: Use `m4_len' not `len'.
19775 2001-08-07 Akim Demaille <akim@epita.fr>

19781 * bin/autom4te.in (handle_output): Typo in quadrigraph substitution.
19783 2001-08-04 Akim Demaille <akim@epita.fr>
19785 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA, AC_FUNC_ERROR_AT_LINE)
19786 (AC_FUNC_FSEEKO, AC_FUNC_OBSTACK): Use AC_LANG_IFELSE, not
19788 * lib/autoconf/headers.m4 (AC_HEADER_MAJOR): Likewise.
19789 * lib/autoconf/fortran.m4 (_AC_LANG_PROGRAM_C_F77_HOOKS)
19790 (AC_F77_MAIN): Likewise.
19792 2001-08-04 Akim Demaille <akim@epita.fr>
19794 Don't rely on M4sugar outputting the patterns in files, since we
19795 might process the output _without_ running m4, hence without these
19798 * lib/m4sugar/m4sugar.m4 (m4_init): No need for `m4_tmpdir'.
19799 * bin/autom4te.in (@Request::includes): Remove, unused.
19800 (@Request::source): Rename as...
19801 (@Request::input): this.
19802 (@preselect): Add `m4_pattern_forbid' and `m4_pattern_allow'.
19803 (&handle_output): Fetch the patterns from the traces.

19806 (m4_pattern_forbid, m4_pattern_allow): Adjust for tracing only.
19808 2001-08-04 Akim Demaille <akim@epita.fr>
19810 `autoconf && autoheader' is sped up. Now, speed up `autoheader &&
19811 autoconf', i.e., in addition to caching traces, cache the output.
19813 * bin/autom4te.in (Request::cache): Rename as...
19814 (Request::id): this.
19815 ($cache, $icache, $tcache, $ocache): New.
19816 (&handle_m4): Save M4 output in the cache instead of $tmp.
19817 (&handle_output): Adjust.
19818 (&up_to_date_p): Check that the output cache is up to date too.
19819 (top level): Run `&handle_m4' iff force or the cache is invalid.
19820 Run `&handle_output' if the output cache is more recent.
19822 2001-08-04 Akim Demaille <akim@epita.fr>
19824 * bin/autom4te.in ($force): New.
19825 (&parse_args, &print_usage): -f, --force is a new option.
19826 (&handle_output): CPP directives might have spaces after `#'.
19827 (&parse_args): The first file only can be frozen.
19829 2001-08-04 Akim Demaille <akim@epita.fr>
19831 Don't let autom4te compute the `include' traces several times:
19832 first check that the trace cache file is up to date, and then
19833 compare its timestamp with that of the output.
19835 * bin/autom4te.in, bin/autoupdate.in, bin/autoscan.in: Normalize
19836 the preamble. Don't require 5.005 as Autom4te::General does it,
19837 and better yet (use `use', not `require'!).
19838 * lib/Autom4te/Struct.pm: Rename the last occurrences of
19839 Class::Struct as Autom4te::Struct.
19840 * lib/Autom4te/General.pm (File::stat): Use it.
19841 (&mtime): New, export it.
19842 * bin/autom4te.in: Use it.
19843 Declare `$req' is invalid if it is outdated.
19844 Don't declare it valid before saving it if something went wrong.
19846 2001-08-04 Akim Demaille <akim@epita.fr>
19848 Autom4te shall not encode Autoconf data, and preselecting traces
19849 must be proposed to the users.
19851 * bin/autom4te.in (@required_trace): Remove.
19853 (&parse_args, &print_usage): -p, --preselect is a new option.
19854 (&up_to_date_p): Adjust.

19894 (m4_divert_pop): Dump the whole diversion stack when a diversion
19896 * bin/autom4te.in (&handle_output): Remember of the first
19897 occurrence of a possibly undefined macro, not the last.

19899 the appear in the output.
19900 * lib/autoconf/Makefile.am (autoconf.m4f): List its dependencies.
19901 * tests/tools.at (autoconf: forbidden tokens, basic)
19902 (autoconf: forbidden tokens, exceptions): No longer sort
19903 autoconf's stderr, as it is now deterministic.
19904 Check that `dnl' is caught.

19926 `END', as `Autom4te::General::END' will be triggered.
19927 * bin/autoupdate.in, bin/autoscan.in: Improve error messages accuracy.
19928 * bin/autoupdate.in (File::Compare, File::Copy): Use them instead of
