1600 Work around DJGPP shell function return bug with command substitutions.
1601 DJGPP bash 2.04 has a bug in that `return $ac_retval' done in a
1602 shell function which also contains a command substitution causes
1603 the shell to barf. For more details and a fix see:
1604 <http://www.delorie.com/djgpp/mail-archives/browse.cgi?p=djgpp-workers/2009/09/09/03:35:08>
1605 Possible workaround include putting the `return' in a subshell
1606 or calling another function to set the status.

1633 DJGPP fix: remove both conftest and conftest.exe.
1634 The DJGPP compiler may create both `a.out' and `a.exe' without -o,
1635 and both `conftest' and `conftest.exe' with `-o conftest', but not
1636 with `-o conftest.exe'.
1637 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_O): Also remove
1638 `conftest' without $ac_exeext suffix.
1640 DJGPP fix: do not try to source /dev/null as cache or site file.
1641 * lib/autoconf/general.m4 (AC_SITE_LOAD, AC_CACHE_LOAD): Do not
1642 load the cache or site file if it is `/dev/null', as DJGPP treats
1643 it as a regular file, but the shell then warns about it later.
1644 Fixes several test suite failures on DJGPP.

6498 (autotools and whitespace in file names): Use them.
6499 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
6500 Cover more potentially problemtic file names. Use the new
6503 Properly handle funny file names for headers in config.status.
6504 The test suite did not cover this bug because the code was not
6505 quoting properly the arguments of `rm -f' (which "fails" silently)
6506 as well as the arguments of `diff' (whose output was redirected to
6507 /dev/null so we couldn't see its error message).
6508 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Properly quote the
6509 file names passed to `rm' and `diff'.
6510 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):

6625 (AT_INIT) <PARSE_ARGS_END>: ...here, since -k always takes
6627 <DEFAULTS>: Delay computation of variables based on $at_dir...
6628 <PREPARE_TESTS>: ...to here, since -C can change $at_dir.
6629 <TESTS>: Re-invoke via absolute name, since -C may be in effect.
6630 <PARSE_ARGS>: Parse new option.
6631 <HELP_TUNING>: Document it.
6632 * tests/autotest.at (Choosing where testsuite is run): New test
6634 (Keywords and ranges): Add test for missing -k argument.
6635 * NEWS: Document this.

6647 * doc/autoconf.texi (Particular Programs): Do not mention the
6648 Autoconf version in which the AC_PROG_INSTALL change was done.
6649 Suggested by Paul Eggert.
6651 2008-01-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6653 Fix --help=recursive with multiple AC_CONFIG_SUBDIRS.
6654 * lib/autoconf/general.m4 (_AC_INIT_HELP): If, for recursive help
6655 mode, we change to the source directory, also set $ac_pwd so we
6656 do not go back to the build tree for the next config subdir.
6657 * tests/torture.at (Deep Package): Extend test to contain two
6658 config subdirs on the top level.
6660 Fix parallel `maintainer-check'.
6661 * Makefile.am (maintainer-check-tests): Depend on `all'.
6662 Use `$(MAKE) $(AM_MAKEFLAGS)' instead of plain `make'.

6712 (m4_require): Use m4_do, not m4_join.
6714 Fix some whitespace tests on cygwin.
6715 * tests/tools.at (autom4te and whitespace in file names): Restore
6716 font-lock. Create $TMPDIR before it might be used.
6718 Fix spurious testsuite failure with M4 1.4.11.
6719 * tests/local.at (AT_CHECK_M4): Cater to new m4 error message.
6721 Optimize AC_REQUIRE.
6722 * lib/m4sugar/m4sugar.m4 (m4_expansion_stack_push, _m4_defun_pro)
6723 (_m4_defun_pro_outer, _m4_defun_epi, _m4_defun_epi_outer)
6724 (m4_require): Avoid extra macro calls.
6726 2007-12-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6728 * tests/torture.at (srcdir): Fix quoting.
6730 Do not pass top_srcdir to configure scripts in testsuite.
6731 * tests/autotest.at (srcdir propagation): Copy install-sh to
6733 (my only test): Drop setting of `top_srcdir'.
6734 * tests/base.at (Input/Output): Likewise.
6735 * tests/local.at (AT_CONFIGURE_AC): Copy install-sh,
6736 config.guess, and config.sub to test source tree.
6737 Drop AC_CONFIG_AUX_DIR setting.
6738 (AT_CHECK_CONFIGURE): Drop setting of `top_srcdir'.
6739 * tests/torture.at (Substitute a 2000-byte string): Drop
6740 AC_CONFIG_AUX_DIR setting, copy install-sh to test source tree.
6741 (Substitute a newline, datarootdir workaround): Likewise.
6742 (Define a newline): Adjust for linenumber changes in configure.ac.
6743 * tests/foreign.at (Libtool): Adjust comment to reflect changes.

6750 * tests/tools.at (Syntax of the shell scripts): Likewise.
6752 * tests/m4sh.at (LINENO): Quote $0.
6754 Fix testsuite program wrapper for whitespace in `pwd`.
6755 The problem here is that the usual mantra is that command
6756 variables can contain arguments, thus we cannot just escape
6757 $AUTOCONF, $AUTOM4TE etc. The compromise is to put the
6758 $top_builddir/tests directory early in $PATH, so that the
6759 wrappers are found by their plain name.
6760 * tests/wrapper.as: Put $testdir early in $PATH.
6761 (AUTOCONF, AUTOHEADER, AUTOM4TE): Set to plain command names.
6763 Proper config.status --file/--header and $srcdir escaping.

6774 Quote $at_group_dir.
6775 * tests/autotest.at (whitespace in absolute testdir): New test.
6777 * lib/autom4te.in: Quote @datadir@.
6779 Proper file name escaping in Autoconf programs and Perl modules.
6780 This includes escaping of characters special to the shell
6781 as well as special to Perl, e.g., leading `<' or `>'.
6782 For example, when $file starts with `>', `open ">$file"'
6783 wrongly tries to append to a different file.
6784 * bin/autoconf.as: Fix quoting for autom4te options.
6785 * lib/Autom4te/General.pm (shell_quote): New function, taken
6786 from coreutils, written by Jim Meyering.

6794 * bin/ifnames.in: Likewise, XFile usage fixes.
6795 * tests/tools.at (autom4te and whitespace in file names): Extend
6796 test. Test twice, with special characters allowed on w32, and the
6797 rest. Test leading and trailing whitespace, for `open_quote'.
6798 (autotools and whitespace in file names): New, analogous test.
6799 Reported by Paul Eggert and Benoit Sigoure, additional suggestions
6800 by Russ Allbery and Eric Blake.

6804 lib/Autom4te/Struct.pm, lib/Autom4te/XFile.pm: Likewise.
6805 * lib/Autom4te/FileUtils.pm (open_quote): New function.
6806 (update_file, contents): Use it.
6808 * Makefile.am (autom4te-update): Rewrite for git.
6810 2007-12-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6812 * doc/autoconf.texi (autom4te Invocation, Autom4te Cache): Fix typos.
6814 Fix copyright years.
6815 * Makefile.am, doc/install.texi, lib/autoconf/fortran.m4,
6816 lib/autoconf/lang.m4, lib/freeze.mk: Likewise.
6818 2007-12-04 Eric Blake <ebb9@byu.net>

6830 Fix AC_C_BIGENDIAN bug caused by new awk method of substitution.
6831 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Don't comment out the
6832 #undef as this runs afoul of our new way of creating config.h.
6833 Problem reported by Jim Meyering in
6834 <http://lists.gnu.org/archive/html/autoconf-patches/2007-11/msg00164.html>.

6838 Fix autom4te for unusual characters in input file names.
6839 * bin/autom4te.in (files_to_options): Quote active characters

6850 `#AT_STOP_...' line at the end of each test.
6852 2007-11-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6854 * lib/autotest/general.m4 (AT_INIT): For awk line number
6855 extraction script, ensure `$at_group' has a defined value
6856 even for the empty set, and properly quote its usage inside
6859 2007-11-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6861 * doc/autoconf.texi (Shell Functions): New chapter. Document
6862 IRIX sh $0 issue in functions, move content from ...
6863 (Portable Shell): ... here.
6864 (Shell Script Compiler): Note that shell functions are not
6865 totally unportable any more.
6867 2007-11-22 Stepan Kasal <kasal@ucw.cz>
6868 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

6878 2007-11-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6880 Fix IRIX testsuite debugging failures: $0 in functions.
6881 * lib/autotest/general.m4 (AT_INIT) <at_func_create_debugging_script>:
6882 Do not use $0 inside a function, as IRIX sh will set that to the
6883 function name rather than the script invocation name.
6885 2007-11-19 Paolo Bonzini <bonzini@gnu.org>
6886 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6888 * lib/autotest/general.m4 (at_func_test): Use cached line numbers

6890 (AT_INIT): Extract and cache test script line numbers.
6892 2007-11-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6894 * lib/autotest/general.m4: Revert 2007-11-15 patch and
6895 subsequent fixups; the awk -> here-document conversion trashes
6896 performance too much with AIX sh.
6898 2007-11-18 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6900 * tests/local.at: Do not test m4, perl with AT_TESTED.
6902 Diagnose and guard against write errors dealing with config.status.
6903 The general idea is this: all write failures from `configure'
6904 writing `config.status' are indicated by $ac_write_error, which
6905 is only checked at the end. This is safe because config.status
6906 code is not executed before the file is complete. Other write
6907 failures, be they inside config.status, or in sub shell/awk
6908 scripts spawned from configure or config.status, typically need
6909 earlier checking, as their results are used right afterwards.
6910 * lib/autoconf/status.m4 (AC_OUTPUT): Initialize `ac_write_fail'
6911 before writing config.status, check afterwards.
6912 (_AC_OUTPUT_FILES_PREPARE, _AC_OUTPUT_FILE)
6913 (_AC_OUTPUT_HEADERS_PREPARE,_AC_OUTPUT_CONFIG_STATUS):
6914 Set `ac_write_error' for write failures to config.status. Barf
6915 upon write failures to temporary files.
6916 Adjust note about closing and reopening the here-document.
6917 (_AC_OUTPUT_HEADER, _AC_OUTPUT_LINK, _AC_OUTPUT_COMMAND)
6918 (_AC_OUTPUT_MAIN_LOOP): Likewise, adjust note about closing and
6919 reopening the here-document.
6920 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
6921 Ensure `ac_write_error' does not escape into config.status.
6922 Also, add a couple of code paths not yet exercised in the test
6923 suite: a config file with input from stdin, and a config header
6925 Suggestion for catching write errors by Bruno Haible.
6927 2007-11-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6929 Avoid error with Tru64 awk and testsuite lines with many words.
6930 * lib/autotest/general.m4 (AT_INIT): In the awk script that
6931 reads the testsuite, set the field separator to an unusual value,
6932 in order to not run over the limit of 199 fields. Tru64 4.0D awk
6933 even splits the input if $i, i>0, was never accessed in the script.
6935 Revert 2007-10-17 change.
6936 * TODO: Multiline args in config files and headers mean something
6937 different and are not fixed, see

6945 AC_*_TOOL does not canonicalize the prefix
6946 * doc/autoconf.texi (Generic Programs): Do not say that

6972 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6974 * lib/autotest/general.m4 (at_func_test): Remove.
6975 (AT_INIT): Pre-extract test groups into separate files.
6976 (AT_CLEANUP): Source pre-extracted file instead of calling at_func_test.
6977 Remove at-test-source files together with the $at_group_dir.
6978 * tests/autotest.at (Long test source lines): New test.
6980 2007-11-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6982 Shell functions and variables may share a namespace.
6983 * doc/autoconf.texi (Portable Shell): Mention Solaris sh
6986 2007-11-14 Paul Eggert <eggert@cs.ucla.edu>
6988 * lib/autoconf/types.m4 (_AC_TYPE_LONG_LONG_SNIPPET): Make comment match
6991 2007-11-14 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6993 * lib/autoconf/status.m4: Fix a couple of comment typos.
6995 * lib/m4sugar/m4sh.m4 (AS_TMPDIR): Use $as_me, not $me.
6997 2007-11-13 Jim Meyering <meyering@redhat.com>
6999 Clean up the rule to create "expr".
7000 * tests/Makefile.am (expr): Don't redirect directly to target.
7001 Redirect just once, not for each echo statement.
7002 Use $@, not literal "expr".
7004 2007-11-13 Paul Eggert <eggert@cs.ucla.edu>
7006 Don't worry about preprocessor when testing long long.
7007 See: http://lists.gnu.org/archive/html/bug-gnulib/2007-11/msg00075.html
7008 * doc/autoconf.texi (Preprocessor Arithmetic): New section.
7009 (AC_TYPE_LONG_LONG_INT, AC_TYPE_UNSIGNED_LONG_LONG_INT):
7010 These no longer check for preprocessor flaws.
7011 * lib/autoconf/types.m4 (_AC_TYPE_LONG_LONG_SNIPPET):
7012 Do not check for preprocessor flaws.
7014 2007-11-13 Jim Meyering <meyering@redhat.com>
7016 Adapt dependencies, now that a version change doesn't modify configure.ac
7017 * GNUmakefile: Remove "make clean" kludge.
7018 * lib/m4sugar/Makefile.am (version.m4): Depend on Makefile, not
7020 Don't redirect directly to target.
7021 Use $@, not literal "version.m4".
7023 2007-11-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7025 * doc/autoconf.texi (Making testsuite Scripts): Document
7026 ":;{" shorthand as in previous patch.
7028 2007-11-12 Paul Eggert <eggert@cs.ucla.edu>
7030 * doc/autoconf.texi (Limitations of Builtins): Document problem
7031 with { ... } a bit more clearly. Suggest ":;{" as a shorthand
7033 * lib/m4sugar/Makefile.am (version.m4): Detect 'echo' failure.
7034 Use ":;{" shorthand.
7035 * tests/Makefile.am ($(srcdir)/package.m4): Likewise.
7037 2007-11-12 Jim Meyering <meyering@redhat.com>
7039 Add more non-srcdir build support.
7040 * GNUmakefile (dummy): Split a long line.
7041 Add -v option to autoreconf invocation.
7043 Remove the autoreconf-provided INSTALL, so that we regenerate it.
7044 * GNUmakefile (dummy): Remove INSTALL.
7046 Remove racy commands to build scripts in bin/ and tests/.
7047 * man/Makefile.am (.x.1): Now that scripts in bin/ and tests/
7048 are guaranteed to be built, remove the rules that tried to build
7049 them. Before, with a parallel build, these rules could lead to
7050 two processes writing tests/wrapper.in concurrently.
7052 Build in man/ only *after* building in bin/ and tests/.
7053 * Makefile.am (SUBDIRS): The man-page-creation process runs $(MAKE)
7054 in both bin/ and tests/.
7056 Accommodate non-srcdir build-from-checkout.
7057 * build-aux/git-version-gen: Require an additional parameter: $srcdir.
7058 Use git's --git-dir=$srcdir/.git option.
7059 Add quotes, in case tarball_version_file contains shell meta-characters.
7060 * GNUmakefile (_curr-ver): Pass $(srcdir) to git-version-gen.
7061 * configure.ac: Pass "." to git-version-gen.
7063 Avoid spurious test failures due to version skew.
7064 * GNUmakefile (dummy): Run $(MAKE) clean after autoreconf -i.
7066 2007-11-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7068 Avoid warnings about conftest.dSYM directories on Mac OS X Leopard.
7069 * lib/autoconf/general.m4 (_AC_LINK_IFELSE, _AC_RUN_IFELSE):
7070 Remove conftest.dSYM directory.
7071 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT)
7072 (_AC_LANG_PROGRAM_C_, _AC_FC_MAIN, __AC_FC_NAME_MANGLING):
7073 Remove `conftest.*' recursively.
7074 * lib/autoconf/lang.m4 (AC_LINK_IFELSE): Likewise.
7075 * lib/autoconf/specific.m4 (_AC_SYS_LARGEFILE_MACRO_VALUE):
7077 (_AC_COMPILER_OBJEXT_REJECT): Reject *.dSYM.
7079 Report and analysis by Jeff Squyres and Peter O'Gorman.
7081 2007-11-12 Benoit Sigoure <tsuna@lrde.epita.fr>
7083 Fix typos in variable names.
7084 * tests/semantics.at (test for AC_CHECK_LIB): s/at_m/ac_m/.
7086 2007-11-11 Benoit Sigoure <tsuna@lrde.epita.fr>
7088 Document that $((expression)) is not portable.
7089 * doc/autoconf.texi (Shell Substitutions): Here.
7091 2007-11-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7093 Ignore configure --help* errors due to LINENO-impaired shells.
7094 * tests/torture.at (Configuring subdirectories, Deep Package):
7095 In the --help* tests in read-only trees, make `.' temporarily
7096 writable again for the `stderr' file, and ignore errors due to
7097 the attempt to write configure.lineno.
7098 Report by Patrick Welche.
7100 2007-11-10 Jim Meyering <meyering@redhat.com>
7102 Generate package.m4 in build-dir, not srcdir.
7103 * tests/Makefile.am (package.m4): Adjust target.
7104 Don't redirect directly to $@.
7105 (CLEANFILES): Add package.m4.
7106 ($(TESTSUITE)): Depend on just-built package.m4, not the one
7108 When running $(AUTOTEST), search "." before searching $(srcdir).
7110 Avoid a race condition that would make parallel "distclean" fail.
7111 * tests/Makefile.am (distclean-generic): Replace the default,
7112 automake-provided rule with an identical one, but with an additional
7113 dependency on distclean-local. Simply adding the dependency would
7114 cause automake not to emit the rule at all.
7115 * BUGS: Building with -jN works, now.
7117 Distribute git-version-gen.
7118 * Makefile.am (EXTRA_DIST): Add build-aux/git-version-gen,
7119 since GNUmakefile is distributed, and requires it for dist* rules.
7121 Remove two more generated files from version control.
7122 * INSTALL: Remove generated file.
7123 * lib/autoscan/autoscan.list: Remove generated file.
7125 2007-11-09 Paul Eggert <eggert@cs.ucla.edu>
7127 * GNUmakefile (PATH): Remove stray apostrophes; they become
7128 part of PATH, which isn't wanted here.
7130 2007-11-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7132 New config files output variable `top_build_prefix'.
7133 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Substitute
7135 * doc/autoconf.texi (Preset Output Variables): Document it.
7137 Report by Bob Friesenhahn.
7139 Avoid expr for arithmetic evaluation if the shell accepts $((...)).
7140 * lib/autotest/general.m4 (AT_INIT) <at_func_arith>: New
7141 function, to parametrize arithmetic with expr vs. the shell.
7142 Use it where possible.
7143 Suggestion by Benoit Sigoure.
7145 2007-11-03 Benoit Sigoure <tsuna@lrde.epita.fr>
7147 Adjust the documentation of autotest WRT atlocal.
7148 * doc/autoconf.texi (Making testsuite Scripts): It is not necessary,
7149 when using Automake, to write a rule to produce atlocal, since it's
7150 an AC_CONFIG_FILES. Mention that atlocal.in needs to be
7151 distributed, not atconfig.in.
7153 2007-11-04 Eric Blake <ebb9@byu.net>
7155 Update list information.
7156 * README: Mention new autoconf-commit list.
7157 * doc/autoconf.texi (Introduction): Mention autoconf-commit list.
7159 2007-11-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7161 * lib/autoconf/functions.m4 (_AC_FUNC_MALLOC_IF): Fix comment typo.
7163 * lib/m4sugar/Makefile.am (version.m4): Another bash bug workaround.
7165 * build-aux/.gitignore: Ignore mkinstalldirs.
7167 * doc/autoconf.texi (autoreconf Invocation): Fix an underfull line.
7169 2007-11-03 Jim Meyering <meyering@redhat.com>
7171 s/-/./ in snapshot version string: 2.61a-256-8b556 -> 2.61a.256-8b556
7172 * build-aux/git-version-gen: This syncs from coreutils.
7174 Adjust the build procedure so "make check" works reliably.
7175 * README-hacking: Include an extra step between "make" and
7176 "make check" to ensure that the latter passes.
7178 Use just-built tools, when possible.
7179 * GNUmakefile (PATH): Set and export here, ...
7180 (dummy): ... rather than here.
7182 2007-11-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7183 and Andreas Schwab <schwab@suse.de>
7185 * tests/Makefile.am ($(srcdir)/package.m4): Work around bash
7188 2007-11-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7190 * configure.ac (AC_PREREQ): Require version 2.60, for
7191 AC_PROG_SED, AC_PROG_GREP.
7193 2007-11-02 Benoit Sigoure <tsuna@lrde.epita.fr>
7194 and Jim Meyering <meyering@redhat.com>
7195 and Andreas Schwab <schwab@suse.de>
7196 and Eric Blake <ebb9@byu.net>
7198 Document a bug in GNU Bash with compound commands and redirections.
7199 * doc/autoconf.texi (Limitations of Builtins): Mention that GNU
7200 Bash doesn't properly set $? when `{ ... } >/bad' fails, and give
7203 2007-11-03 Eric Blake <ebb9@byu.net>
7205 Support m4 1.4.5 in testsuite.
7206 * tests/torture.at (Define a newline): Exclude line numbers in
7208 Reported by Ralf Wildenhues.
7210 2007-11-03 Jim Meyering <meyering@redhat.com>
7212 Remove automake-provided files from version control.
7213 * build-aux/elisp-comp: Remove file.
7214 * build-aux/install-sh: Remove file.
7215 * build-aux/missing: Remove file.
7216 * build-aux/mdate-sh: Remove file.
7217 * build-aux/.gitignore: New file.
7218 Suggestion from Ralf Wildenhues.
7220 2007-11-03 Eric Blake <ebb9@byu.net>
7222 Adjust version comparison to account for git snapshot numbers.
7223 * lib/m4sugar/m4sugar.m4 (_m4_version_unletter): Also treat - as a
7224 component separator.
7225 * doc/autoconf.texi (Number processing Macros)
7226 <m4_version_compare>: Document this change.
7227 * tests/m4sugar.at (m4@&t@_version_compare): Test it.
7229 2007-10-30 Bruno Haible <bruno@clisp.org>
7231 * lib/autoconf/types.m4 (_AC_TYPE_LONG_LONG_SNIPPET): New macro,
7232 extracted from AC_TYPE_LONG_LONG_INT and AC_TYPE_UNSIGNED_LONG_LONG_INT.
7233 (AC_TYPE_LONG_LONG_INT, AC_TYPE_UNSIGNED_LONG_LONG_INT): Use it.
7234 Fixes problem with Sun C 5.[0-8] in 32-bit mode, reported in
7235 <http://lists.gnu.org/archive/html/autoconf-patches/2007-10/msg00210.html>
7236 Suggested by Paul Eggert.
7238 2007-10-28 Jim Meyering <meyering@redhat.com>
7240 * README-hacking: Autoconf, Automake, and Perl are required to build.
7241 List Gzip and Tar separately. Suggested by Ralf Wildenhues.
7243 2007-10-28 Jim Meyering <meyering@redhat.com>
7245 README-hacking: Recommend running autoreconf -vi.
7246 * GNUmakefile (dummy): Use autoreconf -i, with appropriate PATH,
7247 so that we use just-built tools when they're available.
7248 Suggestions from Ralf Wildenhues.
7250 2007-10-28 Jim Meyering <meyering@redhat.com>
7252 Make inter-release --version output more useful.
7254 Now, each unofficial build has a version "number" like 2.61a-19-58dd,
7255 which indicates that it is built using the 19th change set
7256 (in _some_ repository) following the "v2.61a" tag, and that 58dd
7257 is a prefix of the commit SHA1.
7258 * build-aux/git-version-gen: New file.
7259 * configure.ac: Run it to set the version.
7260 (AM_INIT_AUTOMAKE): Don't check NEWS here.
7261 * Makefile.am (dist-hook): Arrange so that .version appears only
7262 in distribution tarballs, never in a checked-out repository.
7263 * .gitignore: Add .version here, too. Just in case.
7264 * tests/Makefile.am ($(srcdir)/package.m4): Depend on Makefile,
7265 not configure.ac, now that the version number changes automatically.
7267 Ensure that $(VERSION) is up to date for dist-related targets.
7268 * GNUmakefile: Arrange to rerun autoconf, if the version reported by
7269 git-version-gen doesn't match $(VERSION), but only for dist targets.
7271 2007-10-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7273 Fix `Deep Package' failure with a configure script early in PATH
7274 * tests/torture.at (Deep Package): Add `.' early in PATH.

7288 Improve corner case of m4_expand.
7289 * lib/m4sugar/m4sugar.m4 (m4_expand, _m4_expand): Rewrite more

7295 2007-10-23 Paul Eggert <eggert@cs.ucla.edu>
7297 * doc/make-stds.texi: Update from gnulib.
7299 2007-10-22 Paul Eggert <eggert@cs.ucla.edu>
7300 and Eric Blake <ebb9@byu.net>

7303 problem reported by Bruno Haible in
7304 <http://lists.gnu.org/archive/html/bug-autoconf/2007-10/msg00027.html>.
7306 2007-10-22 Eric Blake <ebb9@byu.net>
7308 * doc/autoconf.texi (Particular Types): Mention bug in HP-UX 11.00
7311 2007-10-22 Paul Eggert <eggert@cs.ucla.edu>
7313 Don't check for bug in HP-UX 11.00 cpp.
7314 * lib/autoconf/types.m4 (AC_TYPE_UNSIGNED_LONG_LONG_INT):
7315 Use -1ull rather than -1u, since that causes problems with gnulib; see
7316 <http://lists.gnu.org/archive/html/bug-gnulib/2007-10/msg00329.html>.
7318 2007-10-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

7334 escaping of backslash in here-documents.
7336 Fix `Deep Package' test failure on FreeBSD.

7338 unnecessarily. Do not try running `/bin/sh configure' with a
7339 configure script to be found in $PATH, if the shell does not do
7340 this resolution. Fixes test failure on FreeBSD.
7342 Fix config header generation with AIX awk.
7343 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS_PREPARE): In awk
7344 script, use helper array D_is_set, as `" 0"' does not evaluate
7345 to true for AIX awk.
7347 2007-10-21 Eric Blake <ebb9@byu.net>

7382 * lib/autotest/general.m4 (BANNERS): New named diversion.
7383 (TESTS_END): Diversion no longer used.
7384 (AT_INIT) <at_func_banner, BANNERS>: Factor all banners into a
7385 shell function, which prints only as needed, using an associative
7386 array of banner text from a special diversion.
7387 <PARSE_ARGS_END>: No longer need awk to find banners.
7388 <TESTS>: Banners are no longer processed by main driver loop, so
7389 we no longer need case statement.
7390 (AT_BANNER): Rewrite to populate new diversion.
7391 (AT_SETUP): Each test invokes its own banner. No output is needed
7392 to the TESTS diversion.

7419 duplication bug by using new macro.
7420 (AT_INIT) <at_tested>: Restore newline separators. Invoke tested
7421 programs with stdin redirected, so programs that don't
7422 understand --version won't try to behave interactively.
7423 * tests/autotest.at (Tested programs): Catch this bug.
7424 * tests/m4sugar.at (m4@&t@_append): Test new macro.

8485 renamed to "autoconf-invocation"
8487 * doc/autoconf.texi (Caching Results): The CACHE-ID variable
8488 in the examples should not use the internal "ac_" prefix.

8506 2007-05-01 Kevin Ryde <user42@zip.com.au>
8508 * doc/autoconf.texi (Particular Programs): Typo
8509 @acindex{AC_PROG_MKDIR_P} shouldn't have "AC" in that call.
8511 2007-04-30 Paul Eggert <eggert@cs.ucla.edu>
8513 * lib/m4sugar/m4sh.m4 (_AS_SHELL_FN_SPY): Don't imply that
8514 'configure' will fail if the shell lacks proper support for shell
8515 functions. Suggested by RMS.

8519 * doc/autoconf.texi (Limitations of Builtins): Correct the warning
8520 about Solaris /bin/printf '%010000x' 123. Problem reported by
8523 2007-04-28 Paul Eggert <eggert@cs.ucla.edu>
8525 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't look
8526 for a.* when searching for executables, as this prevents users
8527 from having files like a.c. Problem reported by Ralf Wildenhues in:

8539 * NEWS: Document recent changes to AC_CHECK_ALIGNOF, AC_CHECK_SIZEOF,
8540 AC_CHECK_TYPE, AC_CHECK_TYPES.
8541 * doc/autoconf.texi (Generic types): C types must be type-names
8542 (the C terminology), not type-ids (the C++ term). C++ types
8543 must not be anonymous.
8544 * lib/autoconf/types.m4 (_AC_CHECK_TYPE_NEW): Remove special case
8545 for C++; this drops support for anonymous struct and union types,
8546 which were problematic anyway.

8562 * doc/autoconf.texi (Generic Types): Document the restrictions
8563 on types imposed by AC_CHECK_TYPE, AC_CHECK_TYPES.
8564 (Generic Compiler Characteristics): AC_CHECK_SIZEOF now works
8565 with objects too. Document the restrictions on its use.
8566 Document the restrictions on AC_CHECK_ALIGNOF's type argument.
8567 * lib/autoconf/types.m4 (_AC_CHECK_TYPE_NEW):
8568 For C, just try sizeof (TYPE) and sizeof ((TYPE)); if the former
8569 works but the latter doesn't, then it's a valid type.
8570 This lets people use function types and so forth.
8571 For C++ there doesn't seem to be a simple solution, so leave it alone.
8572 (AC_CHECK_SIZEOF): Allow argument to be a variable.
8573 (AC_CHECK_SIZEOF, AC_CHECK_ALIGNOF): Don't bother to invoke
8574 AC_CHECK_TYPE; that wasn't documented or necessary.
8576 2007-04-11 Stepan Kasal <kasal@ucw.cz>
8578 * lib/autoconf/general.m4 (_AC_LINK_IFELSE): Skip AS_TEST_X
8579 when cross-compiling.

8599 * doc/autoconf.texi (Here-Documents, Limitations of Builtins):
8600 (Limitations of Usual Tools): Don't say "older" if Solaris 10 by
8601 default still has the problem. Problem reported by Bruce Korb.

8622 checks for unsigned long long int.
8624 2007-03-19 Paul Eggert <eggert@cs.ucla.edu>
8626 * doc/autoconf.texi (Limitations of Usual Tools): Warn about other
8627 nonstandard grep R.E. escape sequences.
8629 2007-03-17 Jim Meyering <jim@meyering.net>
8631 * doc/autoconf.texi: Adjust grammar around use of "heuristics".
8632 (Limitations of Usual Tools): Also list \< and \>, and mention that
8633 HP-UX's grep, like the one from Solaris, does not support that syntax.
8635 2007-03-09 Stepan Kasal <kasal@ucw.cz>
8637 * doc/autoconf.texi (Specifying Names): `--host' does not
8638 change the build type.

8675 * lib/autotest/general.m4 (AT_INIT): With --clean, return exit
8676 status of rm so we know when it failed.
8677 If cleaning of test dir failed before running the test, warn.
8678 Output the line separator in verbose mode before the warning
8679 to make clear the warning belongs to the following test.

8745 AC_SUBST([MKDIR_P]), so that Automake < 1.10 will pick up its
8746 trace, if a package uses AC_PROG_MKDIR_P explicitly. The actual
8747 substitution will still be done by the special code.

8771 * lib/autoconf/programs.m4 (AC_PROG_SED): When closing a pipe
8772 early on the reader side, drop stderr of the input to avoid
8773 `broken pipe' error output; this may happen even with shell
8774 builtin `echo' of some bash versions. Reports by Ian Macdonald

8792 discussion about the allow_superuser_privileges example,
8793 and change it a bit to make things clearer.
8794 (Optimization and Wraparound): Clarify whether the compiler
8795 will generate an infinite loop for the example derived from
8796 Autoconf's mktime test.
8797 (Signed Overflow Advice): Say that -ftrapv is meant for debugging.
8798 Also, clarify unsigned multiplication overflow.
8800 2007-01-04 Eric Blake <ebb9@byu.net>

8814 * doc/autoconf.texi (Integer Overflow): Revised based on today's
8815 feedback. The most important changes document what happens when
8816 you convert an out-of-range value to a signed integer type, and
8817 say that (sum < a) != (b < 0) reliably detects overflow when sum =
8820 * doc/autoconf.texi (Integer Overflow): Greatly expand and
8821 rewrite, taking notions from the recent discussion on the gcc and
8822 autoconf mailing lists; please see
8823 http://lists.gnu.org/archive/html/autoconf-patches/2006-12/msg00091.html
8824 and follow the many links.

8827 (Signed Integer Division): New sections.
8829 2006-12-28 Steven G. Johnson <stevenj@alum.mit.edu>
8831 * lib/autoconf/general.m4 (AC_DEFINE_TRACE): Don't include
8832 preprocessor macro arguments in traced name.
8833 * doc/autoconf.texi (Defining symbols): Document longstanding
8834 support for AC_DEFINE-ing macros with arguments, and document
8835 behavior when the same variable has multiple AC_DEFINEs.
8836 * lib/autoconf/fortran.m4 (_AC_FC_WRAPPERS): Revert to the
8837 old implementation which AC_DEFINEs the FC_FUNC and FC_FUNC_
8838 macros directly, giving much shorter and simpler code.
8840 2006-12-28 Malcolm Purvis <malcolmp@xemacs.org> (trivial change)
8842 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Insert a
8843 space before "$ac_configure_args" to prevent a 'config.status
8844 --recheck' failure if ac_configure_args doesn't contain a leading
8845 space. This works around a problem with the XEmacs configure.ac,
8846 which uses the (undocumented) ac_configure_args variable
8847 inconsistently with Autoconf.
8849 2006-12-22 Paul Eggert <eggert@cs.ucla.edu>
8851 * lib/autoconf/functions.m4 (AC_FUNC_MKTIME):
8852 Include <limits.h>, and use its INT_MAX to rewrite the
8853 j loop so that it does not overflow 'int'. Problem reported by
8855 <http://lists.gnu.org/archive/html/bug-gnulib/2006-12/msg00084.html>.
8856 Play it safe by shifting left by 1 rather than multiplying by 2,
8857 as GCC is less likely to optimize this away when the value
8858 is signed (when it assumes overflow leads to undefined behavior).
8859 Also, don't assume time_t uses two's complement.
8861 2006-12-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8863 * tests/torture.at (Substitute a 2000-byte string): Avoid using
8864 a 10kB long (multi-line) string literal, OpenServer 5.0.7 ksh
8865 dumps core on it. Report by Tim Rice.

8883 (Configure Option Checking). Tighten up the wording a bit.
8884 (External Software, Package Options): Cross-reference to Option
8885 Checking, and use this to shorten our section.
8886 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Prefer test -n
8887 "$x" to test "x$foo" != x.

8889 Don't warn if $enable_option_checking is "no".
8890 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Initialize
8891 ac_unrecognized_opts to the empty string.
8892 Don't echo the unrecognized opts, as this might mishandle
8893 backslashes or leading -.

8895 usage next to the other --disable-FEATURE options in the

8900 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS, _AC_INIT_PARSE_ARGS):

8903 (AC_DISABLE_OPTION_CHECKING): New macro to disable warnings.
8904 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS, _AC_OUTPUT_SUBDIRS):
8905 Disable option checking when subdirs are configured.

8907 unrecognized --with and --enable options at the end of
8908 the configure output (as well as at the beginning).
8909 * doc/autoconf.texi (Option Checking): New node.
8910 Document new option warning functionality.

8919 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT):
8920 Define HAVE_GETMNTENT to 1, not to the empty string.
8921 Problem originally reported by Jochen Friedrich in
8922 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=403243>.
8924 This change prompted by a problem report by Andrey Simonenko in
8925 <http://lists.gnu.org/archive/html/bug-autoconf/2006-12/msg00026.html>.
8926 * doc/autoconf.texi (Defining Symbols): AC_DEFINE works for
8927 object-like macros only, in the traditional portable character
8929 * lib/autoconf/general.m4 (AC_DEFINE_TRACE_LITERAL):
8930 Warn about attempts to define things that are not identifiers.
8931 * lib/autoconf/fortran.m4 (_AC_FC_WRAPPERS): Rewrite to avoid
8932 awful hack that AC_DEFINEd macro names containing parentheses.
8934 2006-12-12 Paul Eggert <eggert@cs.ucla.edu>
8936 * doc/autoconf.texi: Undo some of the 2006-12-10 change. It was
8937 too drastic, even if Texinfo in theory requires it for info mode.
8939 (config.status Invocation): Renamed back from Recreating a
8941 (Obsolete config.status Use): Renamed back from Obsolete Recreation.
8942 (Autoconf 2.13): Renamed back from 20th-century Autoconf 2.
8944 2006-12-11 Paul Eggert <eggert@cs.ucla.edu>
8946 * NEWS: Version 2.61a.
8948 2006-12-11 Paul Eggert <eggert@cs.ucla.edu>
8949 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8951 * NEWS: Document changes with echo and printf, and the lack
8952 of limits on the total size of multi-line values of substituted
8953 variables, and the AC_FUNC_FSEEKO fix.
8955 2006-12-10 Paul Eggert <eggert@cs.ucla.edu>
8957 * doc/autoconf.texi (Writing Autoconf Input): Renamed from
8958 Writing configure.ac.
8959 (Autoconf Input Layout): Renamed from configure.ac Layout.
8960 (Recreating a Configuration): Renamed from config.status Invocation.
8961 (Obsolete Recreation): Renamed from Obsolete config.status Use.
8962 (acconfig Header): Renamed from acconfig.h.
8963 (20th-century Autoconf 2): Renamed from Autoconf 2.13.
8964 (Writing Testsuites): Renamed from Writing testsuite.at.
8965 (Autom4te Cache): Renamed from autom4te.cache.
8967 * BUGS: Remove mention of VPATH problem, since it's now documented
8968 not to be a bug in the Autoconf build procedure itself, but rather
8969 a problem with the proprietary `make' programs.
8971 * doc/autoconf.texi (Build Directories): Add a cross reference
8974 * build-aux/config.guess, build-aux/config.sub, build-aux/texinfo.tex:
8975 * doc/standards.texi: Sync from gnulib.
8977 * man/autoconf.1, man/autoheader.1, man/autom4te.1, man/autoreconf.1:
8978 * man/autoscan.1, man/autoupdate.1, man/config.guess.1:
8979 * man/config.sub.1, man/ifnames.1: Remove from CVS, since they're
8980 generated automatically.
8982 2006-12-06 Paul Eggert <eggert@cs.ucla.edu>
8984 * lib/autoconf/c.m4 (_AC_PROG_CC_C89): Also try -xc99=all, for Sun
8985 C 5.8 on Solaris 10. Using -xc99=all rather than -xc99 bypasses
8986 the buggy -xc99 option of Forte Developer 7 C on Solaris 9.
8988 2006-12-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8990 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Drop the
8991 `CEOF$ac_eof' special marker, the awk script cannot contain a
8992 line matching `^CEOF', so this is not needed any more.
8993 * tests/torture.at (Substitute a newline): Expose the `%!_!# '
8994 special marker in the test.
8996 2006-12-06 Stepan Kasal <kasal@ucw.cz>
8998 * tests/tools.at (autom4te preselections): Use `find -newer';
8999 remove one of the sleeps.
9001 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE): Make it
9002 more readable, using ...
9003 (_AC_INIT_PARSE_ENABLE2): ... this new helper macro.
9005 * doc/autoconf.texi (autoheader Invocation): Do not double-
9006 quote the parameter of `AH_BOTTOM' in the example.
9008 2006-12-05 Stepan Kasal <kasal@ucw.cz>
9010 * doc/autoconf.texi (Configuration Headers): Remove the
9011 example with multiple input files.
9012 (autoheader Invocation): Encourage `AH_BOTTOM', discouraging
9013 multiple input files.
9015 2006-12-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9017 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): When
9018 creating the awk substitution script, handle one input line at a
9019 time, so that the maximum length of a substituted (multi-line)
9020 value is not limited by the size of the sed pattern space.
9021 The trade-off is a slightly repetitive sed script.
9022 * doc/autoconf.texi (Limitations of Usual Tools): Branch labels
9023 can only have up to 7 characters, due to Solaris 10 /bin/sed.
9024 * tests/torture.at (Substitute a 2000-byte string): Increase the
9025 test with several long lines, they should not be caught by sed
9028 * tests/tools.at (autom4te preselections): New test, to flag
9029 entries missing from autom4te.cfg.
9030 Report by David Byron <dbyron@hheld.com>.
9032 * tests/torture.at (Substitute a 2000-byte string): Actually use
9033 AC_PROG_AWK, so the last change works as intended.
9034 (Substitute and define special characters): Likewise.
9035 (Substitute a newline): Likewise.
9037 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Use `$AWK'
9038 instead of `awk' consistently.
9039 (_AC_OUTPUT_CONFIG_STATUS): Initialize $AWK.
9040 * tests/torture.at (Torturing config.status): Test both the
9041 result of AC_PROG_AWK and plain awk.
9042 (Substitute a 2000-byte string): Likewise.
9043 (Substitute and define special characters): Likewise.
9044 (Substitute a newline): Likewise.
9046 2006-12-04 Paul Eggert <eggert@cs.ucla.edu>
9048 * lib/autoconf/functions.m4 (AC_FUNC_FSEEKO): Check that fseeko
9049 can be assigned to a function pointer. Problem reported by
9050 Peter Palfrader in <http://bugs.debian.org/401377>. Based on
9051 part of a patch by Ralf Wildenhues in that same bug report.
9053 2006-12-01 Paul Eggert <eggert@cs.ucla.edu>
9055 * tests/mktests.sh (ac_exclude_list): Exclude AC_FUNC_SETVBUF_REVERSED.
9056 * tests/semantics.at (AC_FUNC_SETVBUF_REVERSED): New test.
9058 2006-12-01 Eric Blake <ebb9@byu.net>
9060 * lib/autoconf/c.m4 (AC_LANG_INT_SAVE): Avoid newline, to aid in
9061 cross-compiling from cygwin to mingw.
9062 Reported by Bob Rossi. This resurrects the 2000-11-30 patch to
9063 aclang.m4, which was mistakenly removed in the 2001-09-17 patch
9064 to lib/autoconf/c.m4.
9066 2006-12-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9068 * lib/m4sugar/m4sh.m4 (_AS_ECHO_PREPARE): Use a longer test
9069 string for more reliable failure. Wrap the entire test that
9070 causes the broken Solaris printf to dump core, in a subshell,
9071 so the segmentation fault message is reliably suppressed.
9072 Fix shell expansion errors by using /usr/ucb/echo always;
9073 avoid an error on systems without it by another subshell.
9074 Avoid m4 expansion of `$1'. Set the zeroth argument of the
9075 subshell-$as_echo to `as_echo', for better error message.
9077 2006-11-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9079 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): If `BASH_ARGV' or
9080 `BASH_SOURCE' contain a newline, set them to empty, as they may
9083 2006-11-27 Paul Eggert <eggert@cs.ucla.edu>
9085 Turn AC_FUNC_SETVBUF_REVERSED into a noop. It's been obsolete for
9086 years and is too hard to maintain now. The last straw was
9087 reported by Jerker Baeck in
9088 <http://lists.gnu.org/archive/html/autoconf/2006-11/msg00102.html>.
9089 * NEWS: AC_FUNC_SETVBUF_REVERSED is now obsolete.
9090 * doc/autoconf.texi (Particular Functions): Move
9091 AC_FUNC_SETVBUF_REVERSED from here...
9092 (Obsolete Macros): ... to here. Say that it does nothing now.
9093 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
9094 Turn into (almost) a no-op.
9096 * lib/autoconf/c.m4 (AC_PROG_GCC_TRADITIONAL, AC_C_CONST):
9098 Do not recommend via AN_FUNCTION, AN_IDENTIFIER, or AN_HEADER.
9099 These macros are obsolescent and new applications shouldn't need them.
9100 * lib/autoconf/functions.m4 (AC_FUNC_CLOSEDIR_VOID, AC_REPLACE_FNMATCH):
9101 (AC_FUNC_GETLOADAVG, AC_FUNC_GETPGRP, AC_FUNC_MEMCMP):
9102 (AC_FUNC_SELECT_ARGTYPES, AC_FUNC_SETPGRP, AC_FUNC_STAT, AC_FUNC_LSTAT):
9103 (AC_FUNC_STRFTIME, AC_FUNC_SETVBUF_REVERSED, AC_FUNC_UTIME_NULL):
9104 (AC_FUNC_VPRINTF): Likewise.
9105 * lib/autoconf/headers.m4 (AC_HEADER_DIRENT, AC_HEADER_STAT):
9106 (AC_HEADER_STDC, AC_HEADER_SYS_WAIT, AC_HEADER_TIME): Likewise.
9107 * lib/autoconf/types.m4 (AC_STRUCT_TM): Likewise.
9109 * doc/autoconf.texi (Setting Output Variables): Mention that
9110 @VAR1@VAR2 has unspecified behavior. Problem reported by
9112 * NEWS: Mention this.
9114 * Makefile.am: Put only a single '#' into the copyright notice,
9115 so that it's also present in the output file. Standardize wording
9116 in makefile copyright notices to match GNU coding standards.
9117 * bin/Makefile.am: Likewise.
9118 * doc/Makefile.am: Likewise.

9127 * lib/emacs/Makefile.am: Remove copyright notice; it's just a
9130 2006-11-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9132 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Fix error
9133 in the sed script that mangles the awk script: delete up to the
9134 first exclamation mark only.
9135 * tests/torture.at (Substitute and define special characters):
9138 2006-11-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9140 Rewrite config files generation: avoid quadratic growth in
9141 the number of substituted variables by using awk instead of sed
9142 for the bulk of the substitutions.
9143 * NEWS: Mention this.
9144 * doc/autoconf.texi (Setting Output Variables): `|#_!!_#|' is also
9145 forbidden in the output (and thus input) file.
9146 * lib/autoconf/status.m4 (_AC_AWK_LITERAL_LIMIT): New macro.
9147 (_AC_OUTPUT_FILES_PREPARE): Instead of several sed scripts,
9148 generate just one large awk script for substitutions,
9149 eliminating much of the earlier complexity, while adding some
9150 new complexity. Only expand the substitution templates at
9151 configure time, for smaller configure script size. If
9152 _AC_SUBST_FILES are used, test 'awk' for working getline support
9153 at config.status time. If absent, interpolate through the
9154 shell. The awk script was written with much help
9155 from Paolo Bonzini and Paul Eggert.
9156 (_AC_SED_CMD_NUM, _AC_SED_DELIM_NUM, _AC_SED_FRAG): Removed.
9157 (_AC_SED_FRAG_NUM): Likewise.
9158 (_AC_SUBST_CMDS): Renamed from...
9159 (_AC_SED_CMDS): ...this.
9160 (_AC_OUTPUT_FILE): Use _AC_SUBST_CMDS.
9161 * tests/torture.at (Substitute a 2000-byte string): Also
9162 substitute a line with 1000 words, and a variable with several
9164 (Substitute and define special characters): Test awk special
9165 characters, and put substitution input strings `@foo@' in the
9166 output, to test that no recursion happens; test several other
9167 combinations from Paolo Bonzini.
9169 2006-11-25 Paul Eggert <eggert@cs.ucla.edu>
9171 * lib/autotest/general.m4 (AT_INIT): Undo recent changes
9172 that replaced echo with AS_ECHO where this wasn't necessary.
9173 Problem reportd by Ralf Wildenhues.
9174 * lib/m4sugar/m4sh.m4 (_AS_ECHO_PREPARE): Port to Solaris 7,
9175 where "/usr/bin/printf '%s\n' S" dumps core if S is long.
9176 This is Sun bug 4206210. Problem reportd by Ralf Wildenhues.
9178 2006-11-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9180 * lib/freeze.mk (GREP): Removed, no need to initialize this.
9182 2006-11-21 Paul Eggert <eggert@cs.ucla.edu>
9184 * doc/autoconf.texi (Limitations of Usual Tools): Don't claim
9185 that traditional Awk lacks 3-arg "split". It has it.
9186 Mention that FS must be a single character, and a few other
9187 99-byte limits of traditional Awk.
9188 Mention that if (i in a) doesn't work with traditional Awk.
9190 2006-11-18 Paul Eggert <eggert@cs.ucla.edu>
9192 * tests/autotest.at (BSx641-newline in command):
9193 (BS-BS-newline in command, BSx640-newline in command):
9194 (Newline-CODE-BS-newline in command):
9195 (Single-quote-BS-newline in command):
9196 (Single-quote-newline-BS-newline in command):
9197 Use printf '%s\n' instead of echo, for portability to hosts
9198 where echo interprets backslashes. This will break on hosts
9199 that lack printf, but for now let's assume all such hosts
9200 are dead (if not, we should get reports of test failures).
9202 2006-11-17 Paul Eggert <eggert@cs.ucla.edu>
9204 'echo' has some portability problems, when given a first argument
9205 with a leading '-', or when given any argument containing '\'.
9206 Avoid using 'echo' in these cases.
9207 * bin/Makefile.am $(bin_SCRIPTS): Rewrite to avoid 'echo' entirely.

9209 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
9210 * lib/autotest/general.m4 (AT_INIT): Likewise.
9211 * bin/autoconf.as: Use AS_ECHO rather than plain echo, when the
9212 argument might be unportable.

9231 (AS_TR_SH, AS_TR_CPP, AS_VAR_GET): Likewise.
9232 * bin/autoconf.as: Redo verbose flag implementation, as the old
9233 scheme wouldn't work with AS_ECHO.
9234 * lib/autotest/general.m4 (AT_INIT): Likewise.
9235 * lib/autoconf/general.m4 (AC_MSG_RESULT, AC_MSG_RESULT_UNQUOTED):
9236 Don't use ECHO_T, since ECHO_N is now reliable.
9237 * lib/autotest/general.m4 (AT_INIT): Likewise.
9238 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Use sed "$script"
9239 rather than using a here-document to put the script into a file.
9240 (_AC_DO_ECHO): Hoist the eval out of the echo, so that we can
9242 * lib/m4sugar/m4sh.m4 (AS_VAR_GET): Likewise.
9243 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Use
9244 AS_ECHO_N rather than ECHO_N and ECHO_C. This doesn't fix any
9245 bug, but we might as well stop using ECHO_N and ECHO_C internally.
9246 * lib/autotest/general.m4 (AT_SETUP): Likewise.
9247 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N): Likewise.
9248 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
9249 (_AC_OUTPUT_MAIN_LOOP): Rework echo so that it has just one
9250 operand, as AS_ECHO requires. Avoid double file name expansion.
9251 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Invoke _AS_ECHO_PREPARE.
9252 Don't set as_nl, since _AS_ECHO_PREPARE does that now.
9253 (_AS_PREPARE): Comment that _AS_ECHO_N_PREPARE is just for user code.
9254 (AS_ECHO, AS_ECHO_N, _AS_ECHO_PREPARE): New macros.
9255 * tests/c.at (AC_PROG_CPP without warnings, AC_PROG_CPP via CC):
9256 Double-quote strings that would otherwise contain M4 comments.
9257 * tests/m4sh.at (AS_ECHO and AS_ECHO_N): New test.
9259 * configure.ac (AC_INIT): Bump to 2.61a.
9262 2006-11-17 Paul Eggert <eggert@cs.ucla.edu>
9266 * configure.ac (AC_INIT): Bump to 2.61.
9269 * tests/autotest.at (Macro with backslash in a test title):
9270 Comment out for now, as this tests neither fails nor passes
9271 reliably. Problem reported by Ralf Wildenhues.
9273 2006-11-16 Paul Eggert <eggert@cs.ucla.edu>
9275 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE): Fix some typos
9276 in previous change, which caused test failures.

9281 code for --enable, --disable, --with, and --without to...
9282 (_AC_INIT_PARSE_ENABLE): ... a new macro.

9345 first argument may also contain dots.
9347 2006-11-09 Paul Eggert <eggert@cs.ucla.edu>
9349 * tests/mktests.sh (ac_exclude_list): Exclude AC_PROG_CXX_C_O, for
9350 benefit of platforms like Solaris+GCC where it is common to have a
9351 non-working g++ installation.

9363 * lib/autoconf/types.m4 (AC_TYPE_LONG_LONG_INT): Set
9364 ac_cv_type_long_long_int to 'yes' instead of 'cross-compiling'.
9365 Imported from a similar patch to gnulib by Bruno Haible.
9367 2006-11-08 Paul Eggert <eggert@cs.ucla.edu>
9369 * NEWS: New macros AC_C_FLEXIBLE_ARRAY_MEMBER, AC_C_VARARRAYS.

9388 Handle special characters in test case titles correctly.
9389 * lib/autotest/general.m4 (AT_INIT): M4-quote and AS_ESCAPE AT_help_all
9391 (AT_SETUP): M4-quote and AS_ESCAPE the title properly everywhere.
9392 * tests/autotest.at (AT_CHECK_AT_TITLE): Add EXPANDED-TITLE-TO-TEST
9393 argument. Extend to check titles printed by ./micro-suite and
9394 ./micro-suite -l and the title in micro-suite.log.
9395 (Backquote in a test title,
9396 Single-quote in a test title,
9397 Double-quote in a test title): Don't expect failure anymore.
9398 (Backslash in a test title): Put a non-whitespace character after the
9399 backslash so that Bourne shells might actually see it as an escape
9401 (Brackets in a test title,
9402 Pound in a test title,
9403 Comma in a test title,
9404 Quoted Macro in a test title,
9405 Macro in a test title,
9406 Macro with single-quote in a test title): New tests.
9407 (Macro with backquote in a test title,
9408 Macro with double-quote in a test title,
9409 Macro with backslash in a test title): New tests expected to fail.
9410 * tests/torture.at (#define header templates): M4-quote this title in
9411 AT_SETUP call so that no M4 code is commented inadvertently somewhere.
9412 The visible effect was a stray [] in the testsuite output.
9414 2006-10-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9416 * doc/autoconf.texi (Limitations of Builtins): Do not invoke
9417 `trap ... 0' inside a function, for AIX sh.
9419 2006-10-26 Paul Eggert <eggert@cs.ucla.edu>
9421 * tests/base.at (AC_COMPUTE_INT): Test **0** rather than 1 / 0,
9422 since powerpc-apple-darwin8-gcc-4.0.1 (Apple Computer, Inc. build
9423 5363) simply issues a warning when dividing by zero at compile
9424 time. Problem reported by Elias Pipping.
9426 2006-10-26 Eric Blake <ebb9@byu.net>
9429 * doc/autoconf.texi (Evaluation Macros): Improve the example to
9430 show effect on macros that expand with commas.
9431 Reported by Joel E. Denny.

9453 * tools/trace.at (autoconf --trace: user macros): Test `$%'.
9455 2006-10-24 Paul Eggert <eggert@cs.ucla.edu>
9457 * lib/autoconf/specific.m4 (_AC_SYS_LARGEFILE_MACRO_VALUE):
9458 If FUNCTION-BODY is nonempty, use AC_LINK_IFELSE rather than
9459 AC_COMPILE_IFELSE, to work around problem with OSF/1 4.0F fseeko
9460 reported by Nelson H. F. Beebe for Coreutils 6.4.
9462 * tests/tools.at (autoconf --trace: user macros): Remove test
9463 for tracing multiline macros, since m4 1.4.7a uses a different
9464 way to number lines. Problem reported by Ralf Wildenhues.
9466 2006-10-24 Stepan Kasal <kasal@ucw.cz>
9468 * bin/autom4te.in (handle_m4): Do not redirect stdin to
9469 /dev/null since the heuristics for interactive behaviour was
9472 * bin/autom4te.in: With --force, always refresh the output
9473 file. Problem reported by Greg Schafer <gschafer@zip.com.au>.
9475 * bin/autoconf.as: Fix the verbose message at the end.
9477 2006-10-23 Paul Eggert <eggert@cs.ucla.edu>

9491 * doc/autoconf.texi (Caching Results): Likewise.
9492 * lib/autoconf/general.m4 (_AC_CACHE_CHECK_INT): Renamed from
9493 AC_CACHE_CHECK_INT, since it's no longer public.
9494 * lib/autoconf/types.m4: All uses of AC_CACHE_CHECK_INT changed.
9495 * tests/base.at (AC_COMPUTE_INT): Test this, not AC_CACHE_CHECK_INT.

9526 looking for special shell characters.

9540 2006-10-14 Paul Eggert <eggert@cs.ucla.edu>
9542 (Imported from Automake.)
9543 * build-aux/install-sh (posix_mkdir): Reject FreeBSD 6.1 mkdir -p -m,
9544 which incorrectly sets the mode of an existing destination
9545 directory. In some cases the unpatched install-sh could do the
9546 equivalent of "chmod 777 /" or "chmod 0 /" on a buggy FreeBSD
9547 system. We hope this is rare in practice, but it's clearly worth
9548 fixing. Problem reported by Alex Unleashed in
9549 <http://lists.gnu.org/archive/html/bug-autoconf/2006-10/msg00012.html>.
9550 Also, don't bother to check for -m bugs unless we're using -m;
9551 suggested by Stepan Kasal.

9559 is enabled by default with gnu and gnits strictness.
9560 Report from Bruno Haible.
9562 2006-03-10 Alexandre Duret-Lutz <adl@gnu.org>

9564 gnu and gnits modes.
9566 Import this change from Config:

9571 Import this change from Gnulib:
9573 2006-09-16 Karl Berry <karl@gnu.org>
9574 * doc/fdl.texi (ADDENDUM): switch to @heading from @appendixsubsec,
9575 to avoid sectioning errors.
9577 Import these changes from Texinfo:
9579 2006-10-04 Karl Berry <karl@gnu.org>
9580 * build-aux/texinfo.tex (\singlequotechar): rename to \codequoteright.
9581 (\quoteexpand): rename to \rquoteexpand.
9582 (\codequoteleft): new def, to look for @set codequotebacktick.

9584 (\lquoteChar, \rquoteChar, \dashChar, \underChar: new \chardef's.
9585 (\code): must use new \...Char values, since now ` is active.
9587 2006-08-26 Karl Berry <karl@gnu.org>
9588 * build-aux/texinfo.tex (\textdegree): New command.
9590 2006-08-12 Karl Berry <karl@gnu.org>

9595 * doc/autoconf.texi (Autoheader Macros): Fix syntax error.
9597 2006-10-13 Stepan Kasal <kasal@ucw.cz>
9599 * doc/autoconf.texi (Autoheader Macros): Warn that the text
9600 added to the template can get mangled.
9602 2006-10-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9604 * lib/autoconf/functions.m4 (AC_FUNC_OBSTACK): In the test,
9605 include the default headers, and redefine obstack_chunk_alloc
9606 and obstack_chunk_free. Fixes false failure with glibc.
9608 2006-10-12 Paul Eggert <eggert@cs.ucla.edu>
9610 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Set as_executable_p,

9622 * NEWS: AC_USE_SYSTEM_EXTENSIONS now defines _TANDEM_SOURCE for
9623 the NonStop platform.
9624 * doc/autoconf.texi (Posix Variants): Likewise.
9625 * lib/autoconf/specific.m4 (AC_USE_SYSTEM_EXTENSIONS): Likewise.
9627 * lib/m4sugar/m4sh.m4 (AS_TEST_X): New macro.
9628 (AS_EXECUTABLE_P): Use as_test_x rather than as_executable_p.
9629 (_AS_TEST_PREPARE): Set as_test_x rather than as_executable_p.
9630 Use a better substitute, by inspecting the output of "ls"
9631 rather than just using ":".
9632 * lib/autoconf/general.m4 (_AC_LINK_IFELSE): Use AS_TEST_X
9633 rather than AS_EXECUTABLE_P, since we needn't worry about
9634 non-regular files here.
9636 * NEWS: Autoconf-generated shell scripts no longer export BIN_SH,
9637 due to configuration hassles with this. See Tonya Underwood's report
9638 <http://lists.gnu.org/archive/html/bug-autoconf/2006-10/msg00003.html>.

9647 2006-10-11 Stepan Kasal <kasal@ucw.cz>
9649 * lib/m4sugar/m4sh.m4 (AS_BOURNE_COMPATIBLE): Move the
9650 initialization which is not inherited through the environment
9651 (_AS_BOURNE_COMPATIBLE): ... to this new macro.
9652 (_AS_RUN): Call _AS_BOURNE_COMPATIBLE, not AS_BOURNE_COMPATIBLE.
9654 2006-10-09 Paul Eggert <eggert@cs.ucla.edu>
9656 * doc/autoconf.texi (Limitations of Usual Tools): Describe
9657 problems with mkdir -p -m.
9659 2006-10-06 Paul Eggert <eggert@cs.ucla.edu>
9661 * lib/autoconf/c.m4 (_AC_PROG_PREPROC_WORKS_IFELSE): Remove
9662 comment about ac_cpp_err; it was incorrect, and anyway
9663 ac_cpp_err is being removed below.
9664 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE): Don't
9665 set ac_cpp_err to 'yesyes' if preproc_warn_flag and werror_flag
9666 are both 'yes'. In fact, don't bother setting ac_cpp_err at all;
9668 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't log our funky tests
9669 with werror_flag and conftest.err and so forth. This is more
9670 compatible with how _AC_PROG_PREPROC_WORKS_IFELSE behaves,
9671 and anyway the user shouldn't normally want to see this gorp logged.
9672 Problem reported by Ralf Wildenhues.
9673 * lib/autoconf/lang.m4 (AC_LANG_WERROR): werror_flag's default is
9674 empty, not 'no', since the rest of the code uses 'test -z'.
9676 2006-10-04 Paul Eggert <eggert@cs.ucla.edu>
9678 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE):
9679 Use a single call to AC_DO_TOKENS rather than multiple, for
9681 (_AC_LINK_IFELSE): Test that resulting file is executable.
9682 Problem reported by mwoehlke in
9683 <http://lists.gnu.org/archive/html/bug-coreutils/2006-10/msg00048.html>.
9685 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Use "test -x /" rather
9686 than creating a file to use with test -x; this is much faster.
9688 2006-10-02 Bruno Haible <bruno@clisp.org>
9690 * lib/autom4te.in (Automake-preselections): Add
9691 AM_GNU_GETTEXT_INTL_SUBDIR, for automake 1.10.
9693 2006-09-27 Stepan Kasal <kasal@ucw.cz>
9695 * doc/autoconf.texi (Writing testsuite.at): Fix a typo: for
9696 standard error, `experr' should be used, not `expout'.
9698 2006-09-26 Paul Eggert <eggert@cs.ucla.edu>
9700 * lib/autoconf/functions.m4 (AC_FUNC_FSEEKO): Don't compile the
9701 fseeko testing program twice; just use the earlier result.
9702 * lib/autoconf/specific.m4 (_AC_SYS_LARGEFILE_MACRO_VALUE):
9703 Set cache var to 'unknown' (not 'no') if leaving the macro unset
9704 still doesn't let the program compile.
9705 (AC_SYS_LARGEFILE): Test for _LARGE_FILES only if earlier tests
9708 * lib/autoconf/functions.m4: Fix problems reported by Ralf Wildenhues.
9709 (AC_FUNC_ERROR_AT_LINE): Don't bother to check for error.h. Just
9710 include it, without including anything else.
9711 (AC_FUNC_FSEEKO): Avoid gcc -Wall warnings about constant
9713 (AC_FUNC_STRNLEN): Require AC_USE_SYSTEM_EXTENSIONS.
9715 2006-09-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9717 * lib/autoconf/functions.m4 (AC_FUNC_ERROR_AT_LINE): Check for
9718 `error.h', and include it, for a `error_at_line' prototype.
9719 Use a nonempty format string in the link test.
9720 * lib/autoconf/functions.m4 (AC_FUNC_WAIT3): Include <sys/wait.h>,
9721 for a declaration of wait3.

9726 * doc/autoconf.texi (Generic Declarations): Clarify that AC_CHECK_DECL
9727 can apply to constants too, and that it checks for macro defns.
9728 * lib/autoconf/general.m4 (AC_CHECK_DECL): Assume C89 or better,
9729 and simply cast the identifier to void. This handles structure
9730 values. Problem reported by Ralf Wildenhues.
9731 * tests/semantics.at (AC_CHECK_DECLS): Also check enums.
9733 2006-09-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

9820 * lib/autoconf/general.m4 (AC_CONFIG_MACRO_DIR): Do not check

9822 too late, anyway. Problem reported by Stefan Seefeld.

9825 7.1.4 /usr/bin/posix/sh described by Tim Rice in

9830 * tests/local.at (AT_CHECK_M4): Fix this so that the testsuite
9831 works with GNU M4 1.4.3 again; make the normalized form
9832 match the current m4 message; fix the description.

9841 Merge from gnulib as follows: Use AC_CHECK_HEADERS_ONCE instead of

9944 didn't work if some values were cached but not others. Test for
9945 broken lex libraries like native ia64-hp-hpux11.22; see
9946 <http://sources.redhat.com/ml/binutils/2003-12/msg00337.html>, and

10137 less skeptical about "volatile", after discussion with
10138 Bruno Haible on bug-gnulib.
10139 (Limitations of Usual Tools): Warn about sed stripping
10140 leading white space from text. From Bruno Haible.
10142 2006-07-20 Paul Eggert <eggert@cs.ucla.edu>
10144 * lib/autoconf/libs.m4 (AC_PATH_XTRA): Don't use -R if the

10180 reported by Keith Marshall. Also, don't bother with builddir2,
10181 since it shouldn't be needed any more.
10183 2006-07-07 Paolo Bonzini <bonzini@gnu.org>
10185 * doc/autoconf.texi (Generic compiler characteristics):

10204 * lib/autoconf/types.m4 (AC_TYPE_LONG_LONG_INT):
10205 Require that long long int be at least 64 bits wide. C99 requires
10206 this and enough programs depend on it so we should check for it.
10207 Bruno Haible reports in
10208 <http://lists.gnu.org/archive/html/bug-gnulib/2006-06/msg00286.html>
10209 that long long int is 32 bits wide with some nonstandard compilers.

10220 2006-06-28 Paul Eggert <eggert@cs.ucla.edu>
10222 * doc/autoconf.texi: Be more consistent about using @acronym with
10223 "HP" and "HP-UX". Remove mention of OSF; the old version wasn't
10224 quite right (it talked about "OSF/Tru64", even though the
10225 operating systems were called OSF/1, Digital UNIX, and Tru64 UNIX,
10226 and it even mentioned "OSF 4"!) and at this point there's little
10227 reason to talk about OSF any more, since it died in 1994.
10228 (Specific Compiler Characteristics): Simplify example of
10229 negative-size array.
10230 (File Descriptors): Reorder to make the text flow better.
10231 Remove joke about "appreciate the various levels"; I didn't get it.

10238 2006-06-26 Stepan Kasal <kasal@ucw.cz>
10240 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Use -lX11, not
10241 -lXt in LIBS, idea from Karsten Hopp; this was due since
10244 2005-09-18 Paul Eggert <eggert@cs.ucla.edu>
10245 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Look for X11/Xlib.h
10246 and XrmInitialize rather than X11/Intrinsic.h and XtMalloc
10247 (which belong to Xt, not X itself). See Debian bug 327655.

10274 to document the whole `datarootdir' business a bit better.
10276 * tests/torture.at (datarootdir workaround): Extend test.
10277 Prompted by report by Alexandre Julliard.

10296 Use @acronym around BSD, GCC, and GNU when appropriate.
10297 (Why GNU M4): Renamed from "Why GNU m4".
10298 (Redefined M4 Macros): Mention that Posix
10299 m4wrap takes only 1 argument, but GNU M4 1.4.x takes more.

10303 2006-06-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10305 * bin/autom4te.in (handle_output): Do not forbid the empty
10307 * tests/tools.at (autoconf: the empty token): New test.
10309 2006-06-20 Stepan Kasal <kasal@ucw.cz>
10311 * lib/m4sugar/m4sugar.m4 (m4_init): Merge the two m4_wrap
10312 calls, so that we do not care whether they are LIFO or FIFO;
10313 in the m4_wrap, do not check which diversion is the topmost
10314 one, just check that the stack is balanced at the end.
10315 * lib/m4sugar/m4sh.m4 (AS_INIT): We are going to change the
10316 base diversion forever--pop the previous diversion before
10317 opening the new one; consequently, remove the m4_wrap call.
10318 * lib/autotest/general.m4 (AT_INIT): Likewise.
10319 * tests/m4sugar.at: Do not use
10320 m4_wrap([m4_diversion_pop([..])]), for educational purposes.
10322 2006-06-19 Paul Eggert <eggert@cs.ucla.edu>
10323 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10325 * NEWS: Document that m4wrap/m4_wrap might not be LIFO.
10326 * doc/autoconf.texi (Redefined M4 Macros): Likewise.
10327 Rework example of m4wrap token-pasting trouble so that it doesn't
10328 care whether it's LIFO or FIFO.
10329 Fix some "contrary to"s that are awkward in English.
10331 2006-06-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10333 * lib/autoconf/types.m4 (_AC_TYPE_INT): Set `$ac_cv_c_int$1_t'
10334 to `yes' instead of `int$1_t' if the type is found, for more
10335 consistent configure output (where $1 is the number of bits).
10336 (_AC_TYPE_UINT): Likewise for `uint$1_t'.
10337 Suggested by Bruno Haible.
10339 * lib/autoconf/types.m4 (_AC_TYPE_UNSIGNED_INT): Solaris 2.5.1
10340 needs _UINT8_T and _UINT64_T defines as well, to avoid clashes
10341 with system headers. Report by Bruno Haible.
10343 2006-06-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10345 * config/config.guess, config/config.sub: Sync from upstream.
10347 * bin/Makefile.am (autoconf.in): Use `--melt' for autom4te,
10348 in order to avoid picking up an older installed frozen m4sh.m4f.
10349 Besides an outdated shell startup, this could have been created
10350 by an earlier M4 version with incompatible frozen file format.
10352 2006-06-16 Paul Eggert <eggert@cs.ucla.edu>
10354 * README: Recommend m4 1.4.4 instead of 1.4.3..
10355 * doc/autoconf.texi: Likewise.
10356 (Special Chars in Names): Say that $(.FOO) is portable, as
10357 suggested by Stepan Kasal.
10358 (Installation Directory Variables, Build Directories):
10359 (Automatic Remaking, Subdirectories, Fortran Compiler):
10360 (Making testsuite Scripts, Defining Directories):
10361 Quote variable usages better.
10362 (Making testsuite Scripts): Add clean-local rule to makefile
10363 snippet, by Eric Blake.
10364 (Installation Directory Variables): Fix table item font.
10365 Reword slightly to clarify. Generalize advice about
10366 not using special characters to include all file-related
10367 vars, not just VPATH.
10368 (Special Chars in Variables): Warn about special characters in
10370 (Assignments): Clarify default-value example as suggested by
10372 <http://lists.gnu.org/archive/html/autoconf-patches/2006-06/msg00072.html>.
10373 (Special Shell Variables): Note leading ./ or ../, as suggested
10375 (Limitations of Builtins): Under cd, warn about CDPATH.
10376 (The Make Macro MAKEFLAGS): Untabify. Problem reported by
10379 2006-06-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10381 * doc/autoconf.texi (Configuration Actions): Remove duplicate
10382 `@var', for texi2html.
10383 (Systemology): Some more word wrapping, for DVI output.
10384 (autom4te Invocation): The short option for `--melt' is `-M',
10387 2006-06-15 Paul Eggert <eggert@cs.ucla.edu>
10389 * doc/autoconf.texi: More formatting and English tweaks,
10390 many suggested by Ralf Wildenhues.
10391 Reword to avoid "@code{...}'s" and the like, since it's ugly
10392 with Emacs info mode. discontents -> woes.
10393 Put a few "will"s back. time stamp -> timestamp.
10394 side-effect -> side effect.
10396 2006-06-14 Paul Eggert <eggert@cs.ucla.edu>
10398 * doc/autoconf.texi (Initializing configure, Shell Substitutions):
10399 Warn about $@ not persisting. Problem reported by Julien Danjou in
10400 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=372179>.
10401 (Special Chars in Names): Renamed from Leading _ in Macro Names.
10402 Mention other special chars, too.
10404 2006-06-14 Eric Blake <ebb9@byu.net>
10406 * doc/autoconf.texi (The Make Macro MAKEFLAGS): New node.
10408 2006-06-13 Paul Eggert <eggert@cs.ucla.edu>
10410 * doc/autoconf.texi: Some systematic minor improvements, as
10411 follows. Use "makefile" when talking about makefiles
10412 generally (which might be named "makefile" or "Makefile" or even
10413 "foo.mk"), "Makefile" when talking about a specific makefile
10414 called "Makefile". This unclutters the text from weird quotes
10415 (e.g., "`Makefile's" in info mode). Similarly, use "@var{foo}
10416 values" rather than "@var{foo}s" and similar constructs containing
10417 "}s". Use "Make rules" rather than "Makefile rules". Minor
10418 English-language improvements. Change the prefix "sub-" to "sub"
10420 Put blank lines around examples more consistently.
10421 Avoid "rather" and "very" as intensifiers.
10422 Avoid "will" as an auxiliary.
10423 (Limitations of Make): Split this node into....
10424 (Portable Make, $< in Ordinary Make Rules, Failure in Make Rules):
10425 (Leading _ in Macro Names, Backslash-Newline-Newline):
10426 (Backslash-Newline Comments, Long Lines in Makefiles):
10427 (Macros and Submakes, The Make Macro SHELL, Comments in Make Rules):
10428 (obj/ and Make, make -k Status, VPATH and Make):
10429 (VPATH and Double-colon, $< in Explicit Rules):
10430 (Automatic Rule Rewriting, OSF/Tru64 Directory Magic):
10431 (Make Target Lookup, Single Suffix Rules, Timestamps and Make):
10432 New nodes, resulting from splitup of Limitations of Make.
10433 All cross-references changed. Raise the top node from
10434 a section to a chapter, and all subnodes accordingly.
10435 Redo the introductory wording to match the new organization.
10436 (Installation Directory Variables): Use an example that is
10437 closer to what Autoconf actually does. Mention that VPATH's
10438 value should not contain metacharacters or white space.
10439 (Fortran Compiler): Fix a VPATH bug in an example.
10440 (Leading _ in Macro Names): Mention that this problem is no longer
10441 of practical concern.
10442 (VPATH and Make): Reword the advice to make it clearer
10443 that Autoconf and Automake support VPATH in non-GNU make, but
10444 many packages have bugs in this area.
10445 ($< in Explicit Rules): Refer to Build Directories rather
10446 than using a (non-VPATH-safe) example.
10447 (Automatic Rule Rewriting): Mention the sort of disaster that
10448 can ensue with Solaris-style rule rewriting with VPATH.
10450 2006-06-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10452 * doc/install.texi (Compilers and Options): Weaken the
10453 suggestion to use GNU make for VPATH builds.
10455 * lib/autom4te.in (Automake-preselections): Add AM_PROG_CXX_C_O,
10456 AM_PROG_F77_C_O, AM_PROG_FC_C_O, AC_FC_SRCEXT, AC_FC_FREEFORM.
10458 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Fix M4 quotation
10459 in regular expression.
10461 2006-06-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10463 * doc/autoconf.texi (Installation Directory Variables):
10464 Drop extra @samp from `@table @samp' item.
10465 (Limitations of Usual Tools): Comment fix.
10466 Do not nest @samp just to point to other table items.
10467 (Writing testsuite.at) <AT_CHECK>: The second argument to
10468 `@dvar' is already @samp'ed.
10469 (Making testsuite Scripts) <AC_CONFIG_TESTDIR>: Likewise,
10470 do not use @var in the second argument.
10472 2006-06-07 Paul Eggert <eggert@cs.ucla.edu>
10474 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Look for
10475 $as_shell.exe too. Problem reported by Andreas Buening in
10476 <http://lists.gnu.org/archive/html/autoconf/2006-06/msg00038.html>.
10478 2006-06-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10480 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA): Work around
10481 `unused variable' compiler warning, for `-Wall -Werror'.
10482 Reported by Jaap Haitsma in
10483 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00012.html>.
10485 2006-06-06 Paul Eggert <eggert@cs.ucla.edu>
10487 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Remove core file, in
10488 case the compiler dumps core. Problem reported for
10489 OpenServer 5.0.7 by Tim Rice in
10490 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00019.html>.
10491 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE):
10494 2006-06-06 Tim Rice <tim@multitalents.net>.
10496 * lib/freeze.mk: Quiet check-forbidden-patterns so the string
10497 "ERROR" only shows up in "make check" output if there is an
10500 2006-06-06 Eric Blake <ebb9@byu.net>
10502 * tests/tools.at (automatically allowed tokens): Fix typo.
10504 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
10506 * NEWS: Don't blame non-GNU VPATH compatibility issues on Automake.
10508 * doc/autoconf.texi (Integer Overflow): Mention that INT_MIN % -1
10509 typically overflows on x86 CPUs, even though the C standard
10510 requires otherwise.
10512 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10514 * configure.ac (AC_INIT): Bump to 2.59e.
10517 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10521 * config/texinfo.tex: Sync from upstream.
10523 * bin/autoreconf.in: Trace `LT_CONFIG_LTDL_DIR'; if it has been
10524 seen, invoke libtoolize with `--ltdl' argument.
10525 * lib/autom4te.in (Autoreconf-preselections): Adjust.
10527 Suggested by Eric Blake.
10529 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
10531 * NEWS: Whoops! AC_FUNC_STRNLEN isn't obsolescent. Problem
10532 reported by Ralf Wildenhues.
10533 * doc/autoconf.texi (AC_FUNC_STRNLEN): Likewise.
10535 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

10543 2006-06-05 Stepan Kasal <kasal@ucw.cz>
10545 * lib/m4sugar/m4sugar.m4 (m4_require): Modify the error
10546 message issued by AC_REQUIRE.
10547 * tests/m4sugar.at: Check m4_require's error message.
10548 * tests/base.at: Check AC_REQUIRE's error message.
10549 * tests/local.at (AT_CHECK_M4): New macro, almost identical
10551 (AT_CHECK_AUTOM4TE): ... which is now a thin wrapper around
10553 (AT_CHECK_AUTOCONF): Use AT_CHECK_M4; no longer support
10554 `expout' as the last parameter.
10555 * tests/tools.at: Adapt to the above change.
10557 2006-06-04 Stepan Kasal <kasal@ucw.cz>
10559 * doc/autoconf.texi (Limitations of Usual Tools): Correct
10560 information about race-free implementations of mkdir.
10562 2006-06-04 Eric Blake <ebb9@byu.net>
10564 * bin/autoreconf.in (help): Document M4 environment variable.
10565 * bin/autoconf.as (Usage): Likewise.
10566 * bin/autom4te.in (help): Likewise.
10567 * doc/autoconf.texi (autom4te Invocation): Likewise.
10569 2006-06-04 Paul Eggert <eggert@cs.ucla.edu>
10571 * NEWS: GNU make now recommended for VPATH builds.
10572 Mention that some macros are now documented to be obsolescent.
10573 * doc/autoconf.texi:
10574 Prefer "current" to "modern" to describe
10575 currently-used (albeit perhaps old-fashioned) hosts.
10576 Mention which ancient features no longer need to be worried about.
10577 setgid -> set-group-ID
10578 setuid -> set-user-ID (these are the Posix terms)
10579 Fix some misuses of "only".
10580 (AC_C_BACKSLASH_A, AC_C_CONST, AC_C_PROTOTYPES):
10581 (AC_C_STRINGIZE, AC_C_VOLATILE, AC_FUNC_CLOSEDIR_VOID):
10582 (AC_FUNC_GETPGRP, AC_FUNC_LSTAT, AC_FUNC_MEMCMP):
10583 (AC_FUNC_SELECT_ARGTYPES, AC_FUNC_SETPGRP):

10587 (AC_HEADER_SYS_WAIT, AC_HEADER_TIME, AC_ISC_POSIX):
10588 (AC_PROG_GCC_TRADITIONAL, AC_STRUCT_TM):
10589 Mention that these macros are obsolescent.
10590 (Installation Directory Variables): shall -> should
10591 (File Descriptors): Mention that 0, 1, 2 might get reopened.
10592 Mention that it's now safe to use 3 and 4.
10593 (Limitations of Usual Tools): cp -r is now specified by Posix.
10594 Omit longwinded and obsolescent discussion of cp -f.
10595 Modernize discussion of expr, ls.
10596 (Limitations of Make): Modernize discussion of VPATH builds.
10597 Mention $? as a workaround in some cases.
10598 * doc/install.texi (Basic Installation):
10599 Mention "./configure; make; make install" first. Be more
10600 specific about why this file is generic. Remove unnecessary
10601 parens. Remove misleading "only". Remove obsolete advice
10602 about csh. Don't say "configure" takes awhile; say it
10603 might take a while. Suggest CFLAGS=-g rather than CFLAGS=-O2,
10604 and CC=c99 rather than CC=c89, as these are blessed by current
10605 Posix. Recommend GNU make if doing a VPATH build.
10607 2006-06-03 Paul Eggert <eggert@cs.ucla.edu>
10609 * doc/autoconf.texi: Use a consistent style "$ @kbd{...}" for
10610 examples involving shell prompts.
10612 2006-06-02 Stepan Kasal <kasal@ucw.cz>
10613 and Paul Eggert <eggert@cs.ucla.edu>
10615 * doc/autoconf.texi (Here-Documents): Add details about the
10616 pre-ksh93g bug. Reword slightly to make it clearer. Consistently
10617 use "here-documents" instead of "here documents".
10619 2006-06-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10621 * config/texinfo.tex, doc/standards.texi: Sync from upstream.
10623 2006-06-01 Paul Eggert <eggert@cs.ucla.edu>
10625 * doc/autoconf.texi (File System Conventions): Warn about ":"
10626 anywhere in directory names.
10628 2006-05-31 Paul Eggert <eggert@cs.ucla.edu>
10630 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be even more conservative
10631 about quoting the case statement, just in case.
10632 * doc/autoconf.texi (Here-Documents): Mention that the ksh bug
10633 was fixed in ksh93g; reported by Ralf Wildenhues.
10635 2006-05-31 Stepan Kasal <kasal@ucw.cz>
10637 * doc/autoconf.texi (System Services): Do not document
10638 overriding EXEEXT via ac_cv_exeext=ext.
10639 (Particular Programs) <AC_PROG_MKDIR_P>:
10640 Document that ${MKDIR_P} understands --.
10641 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Improve the
10644 2006-05-31 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10646 * lib/m4sugar/m4sh.m4 (_AS_DIRNAME_PREPARE): Guard against test
10647 argument with leading hyphen. Problem reported by Paul Eggert.
10649 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
10651 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be more conservative
10652 about quoting ac_try: quote all of it, if any of it seems suspicious.
10653 This means we don't have to worry about ${ or sed any more.
10654 Also, double-quote the case statement, to work around misuses via
10655 underquoting as reported by Ralf Wildenhues in
10656 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00169.html>.
10657 (_AC_EVAL_STDERR): Revert, since evidently some packages rely on this
10658 undocumented and dangerous macro.
10659 Problem reported by Ralf Wildenhues in
10660 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00168.html>.
10662 2006-05-31 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10664 * lib/m4sugar/m4sh.m4 (_AS_DIRNAME_PREPARE): Check whether
10665 `dirname -- /' returns `/', for SunOS dirname scripts that escaped.
10666 Report by Sam Sirlin <sam@kalessin.jpl.nasa.gov>.
10668 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
10670 * lib/autoconf/general.m4: Revert AC_TRY_EVAL and AC_TRY_COMMAND,
10671 since evidently some packages rely on the old, broken behavior.
10672 Problem reported by Ralf Wildenhues in
10673 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00160.html>.
10674 (AC_TRY_EVAL, AC_TRY_COMMAND, _AC_EVAL): Go back to the
10675 pre-2006-05-26 definitions, but leave in the comments that
10676 these macros are dangerous and should not be used.
10677 (_AC_DO_ECHO): Renamed from _AC_EVAL_ECHO. All callers changed.
10678 (_AC_DO): Renamed from _AC_EVAL. All callers changed.
10679 (_AC_DO_STDERR): Renamed from _AC_EVAL_STDERR. All callers changed.
10680 (_AC_DO_VAR): Renamed from AC_TRY_EVAL.
10681 (_AC_DO_TOKENS): Renamed from AC_TRY_COMMAND.
10683 2006-05-29 Paul Eggert <eggert@cs.ucla.edu>
10685 * lib/autoconf/status.m4 (AC_OUTPUT_MAKE_DEFS): Rewrite to avoid
10686 the use of 'tr', since this is our only use of 'tr'.
10688 2006-05-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10689 and Paul Eggert <eggert@cs.ucla.edu>
10691 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE):
10692 Don't assume 'grep' works on long lines, since AIX grep doesn't.
10694 2005-05-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10696 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Do not use `grep' on
10697 the output file in the `${datarootdir}' test.
10699 2005-05-28 Stepan Kasal <kasal@ucw.cz>
10700 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10702 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If we have not seen
10703 mention of `datarootdir' in the input file(s), but literal
10704 `${datarootdir}' in the output file, and we haven't warned yet,
10705 then warn as well: the user may have (erroneously) used
10706 `AC_SUBST([mydatadir], [$datadir/my])' instead of the correct
10707 `AC_SUBST([mydatadir], ['${datadir}/my'])'.
10708 * tests/torture.at (datarootdir workaround): Extend this test.
10711 2006-05-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10712 and Paul Eggert <eggert@cs.ucla.edu>
10714 * doc/autoconf.texi (autoheader Invocation): The first argument to
10715 `AC_DEFINE_UNQUOTED' need not be a literal. Mention the
10716 alternatives and clear up the language a bit.
10718 2006-05-27 Paul Eggert <eggert@cs.ucla.edu>
10720 * NEWS: Reword notice for AC_TRY_COMMAND, AC_TRY_EVAL,
10721 ac_config_guess, ac_config_sub, ac_configure.
10722 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
10723 Fix typo that prevented an unnecessary space from being removed.
10724 Problems reported by Ralf Wildenhues in:
10725 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00143.html
10727 2006-05-26 Paul Eggert <eggert@cs.ucla.edu>
10729 * doc/autoconf.texi (Particular Programs, Limitations of Usual Tools):
10730 Use better wording to talk about AC_PROG_MKDIR_P's thread-safety.
10731 Don't use the term "thread-safe" to talk about mkdir race
10732 conditions, since the problem is more a process than a thread
10733 issue. Problem reported by Stepan Kasal in:
10734 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00088.html
10735 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Use code that mimics
10736 the test for 'install' more closely. Look at MKDIR_P first.
10737 Look in the PATH, and at /opt/sfw/bin.
10738 Look for a 'gmkdir' program as well (Solaris 10 /opt/sfw/bin/gmkdir).
10739 Don't bother to try mkdir -p, since we already check mkdir --version;
10740 just look at the version number. (There's no easy way to check
10741 for race-free implementations.)
10742 * tests/tools.at (autoconf: subdirectories): Adjust to above
10743 changes, since MKDIR_P now might end in "/mkdir -p".
10745 * doc/autoconf.texi (autoheader Invocation): Mention that the
10746 first arg of AC_DEFINE_UNQUOTED must be a literal.
10747 Problem reported by Ben Pfaff in
10748 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00090.html>.
10750 * NEWS: Mention that AC_TRY_COMMAND and AC_TRY_EVAL may be removed.
10751 * doc/autoconf.texi (Special Chars in Variables): New section.
10752 (Preset Output Variables): Warn about special chars in CPPFLAGS.
10753 (Installation Directory Variables): Quote $(datadir) better.
10754 (Limitations of Builtins): Describe some of eval's trickiness.
10756 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Simplify quoting.
10757 * lib/autoconf/fortram.m4 (_AC_PROG_FC_V_OUTPUT): Likewise.
10758 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Put leading space
10759 in front of every arg, not just trailing args. Quote apostrophes.
10760 (_AC_EVAL_ECHO): New macro.
10761 (_AC_EVAL, AC_EVAL_STDERR): Use it. Quote arg of eval.
10762 (AC_TRY_EVAL, AC_TRY_COMMAND): Mention that these macros might get
10764 (_AC_LINK_IFELSE): Use proper rule for shell continuation lines,
10765 exposed by quoting of eval argument. Put the command on line line
10767 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): Use eval more safely.
10768 (_AC_PATH_X, AC_PATH_X): Quote more safely.
10769 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Use eval more safely.
10770 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Don't use eval.
10771 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Minor style change.
10772 Handle special chars in prefix, ac_srcdir, ac_aux_dir.
10773 Use eval more safely.
10774 (_AC_OUTPUT_CONFIG_STATUS): Adjust to above changes.
10775 * lib/m4sugar/m4sh.m4 (AS_VAR_GET): Note that this API needs
10777 * tests/base.at (AC_TRY_COMMAND): Use proper rule for shell continuation
10778 lines, exposed by quoting of eval argument.
10780 2006-05-26 Stepan Kasal <kasal@ucw.cz>
10781 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10783 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Drop the
10784 initialization of `ac_cv_exeext', do not override it if it was
10785 already set, unless it was set to `no', for compatibility with
10786 Autoconf-2.13, and comment this.
10787 Do not export `ac_cv_exeext', Libtool hasn't needed this for years.
10788 (_AC_COMPILER_EXEEXT_DEFAULT): Likewise, do not export it.
10789 (_AC_COMPILER_EXEEXT_WORKS, _AC_COMPILER_EXEEXT_CROSS): Typos.
10790 * doc/autoconf.texi (Compilers and Preprocessors) <EXEEXT>:
10791 Document that this test may be overridden by setting
10794 2006-05-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10796 Revert these two patches:
10798 2006-04-06 Eric Blake <ebb9@byu.net>
10799 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_O): Inside cache
10800 check, s/ac_exeext/ac_cv_exeext/. Fixes regression introduced
10803 2006-04-01 Stepan Kasal <kasal@ucw.cz>
10804 Clean up _AC_COMPILER_EXEEXT* macros.
10805 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't try to
10806 detect exeext, it will be done by _AC_COMPILER_EXEEXT_O; just set
10807 ac_file to the name of the default output file and call
10808 _AC_COMPILER_EXEEXT_WORKS. Move the definition of ac_files and the
10809 initial `rm' of the candidate files...
10810 (_AC_COMPILER_EXEEXT): ... here and simplify them. Moreover, use
10811 the same list in subsequent `rm' calls, and for the temporary
10812 redefinition of ac_clean_files; call _AC_COMPILER_OBJEXT at the end,
10813 and don't call the other _AC_COMPILER_EXEEXT_* macros directly, use...
10814 (_AC_COMPILER_EXEEXT_TESTS): ... this new macro.
10815 (_AC_COMPILER_EXEEXT_O): Don't export ac_cv_exeext, it's not needed (or
10816 no longer needed) by libtool. Make it a cache check.
10817 (_AC_COMPILER_EXEEXT_CROSS): Remove the comment, it was obviously
10818 copied here by mistake.
10819 (AC_NO_EXECUTABLES): Redefine _AC_COMPILER_EXEEXT_TESTS, not
10820 _AC_COMPILER_EXEEXT.
10821 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX, AC_PROG_OBJC): Do not call
10822 _AC_COMPILER_OBJEXT directly.
10823 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
10825 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10827 * doc/autoconf.texi (Limitations of Usual Tools) < sed (`t')>:
10828 Fix description of how the buggy `sed' works.
10830 2006-05-25 Noah Misch <noah@cs.caltech.edu>
10832 Sync from Automake:
10834 * lib/Autom4te/XFile.pm (lock): Allow EOPNOTSUPP, besides
10835 ENOLCK. Only mention `make -j' when applicable. Only raise
10836 fatal errors when `make -j' is involved. Improve error message.
10838 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10840 * doc/autoconf.texi (Here-Documents): We now know more about
10841 the variable expansion in here documents bug.
10842 Thanks to Tim Rice and Stepan Kasal.
10844 * doc/autoconf.texi (Making testsuite Scripts): Add an example
10845 how to use TESTSUITEFLAGS. Suggested by Eric Blake.
10847 2006-05-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10849 * tests/autotest.at (Multiline command from M4 expansion):
10850 No failure to be expected if the shell quotes newlines in
10851 commands in the `set -x' output. Report by Tim Rice.
10854 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
10856 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Don't use shell
10857 expansion in the here-documents used by config.status, as that
10858 runs afoul of the Korn shell version M-12/28/93d bug described in
10859 the Autoconf manual, and this in turn causes a Coreutils 5.95 build to
10860 fail as described by Tim Rice and diagnosed by Ralf Wildenhues in
10861 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00082.html>.
10863 2006-05-23 Jim Meyering <jim@meyering.net>
10865 * lib/autoconf/functions.m4 (AC_FUNC_LSTAT_FOLLOWS_SLASHED_SYMLINK):
10866 Fix typo introduced with 2006-04-02 change. It reversed the sense
10869 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
10871 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Simplify ac_dA and
10872 ac_dB slightly, to save bytes in the script.
10873 Max out at 50 lines, rather than 96; this is more likely
10874 (though not guaranteed) to avoid obscure 'sed' failures.
10876 2006-05-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10878 * lib/autotest/general.m4 (AT_INIT): UnixWare `tr' may interpret
10879 `tr -d -' as bad option argument. Work around this by deleting
10880 an unrelated character.
10881 Report by Tim Rice <tim@multitalents.net>.
10883 2006-05-22 Paul Eggert <eggert@cs.ucla.edu>,
10884 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
10885 Stepan Kasal <kasal@ucw.cz>
10887 * doc/autoconf.texi (Particular Programs): Do not promise that
10888 we always prefer the GNU version of the program, and that we
10889 search according to PATH; both rules can have exceptions.
10890 Update description of AC_PROG_GREP, AC_PROG_EGREP, AC_PROG_FGREP,
10891 AC_PROG_SED. Move descriptions of limitations
10892 to the Limitations of Usual Tools section.
10893 (Limitations of Usual Tools) <sed>: Mention script length
10894 limitations with Solaris /usr/ucb/sed.
10895 <grep>: Fix wording for empty alternative. Mention that -c and
10896 -l should not be combined, and that -E and -F should not be
10899 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
10900 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10902 * lib/autoconf/programs.m4 (AC_PROG_SED): Catch script length
10903 limits in Solaris 8 /usr/ucb/sed by testing a long script.
10905 2006-05-22 Stepan Kasal <kasal@ucw.cz>
10907 * doc/autoconf.texi (Defining Symbols): Literal parameter of
10908 AC_DEFINE is now passed to m4_pattern_allow.
10909 * NEWS: Mention that; likewise for AC_SUBST.
10910 * lib/autoconf/general.m4 (AC_DEFINE_TRACE_LITERAL): Pass
10911 the parameter to m4_pattern_allow.
10912 * tests/tools.at: Add a check for that.
10914 2006-05-22 Stepan Kasal <kasal@ucw.cz>
10916 * lib/autoconf/status.m4: Fix typos.
10918 2006-05-21 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10920 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Remove
10921 only the files that this macro generates.
10923 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
10925 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: For
10926 the HP-UX sed limitation of 99 commands, labels do not count.
10927 * lib/autoconf/status.m4 (_AC_SED_CMD_LIMIT): Mention that
10929 (_AC_OUTPUT_HEADER): Revert the change from 2006-05-19.
10931 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
10933 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT):
10934 Import the following fix from coreutils:
10936 2006-01-13 Jim Meyering <jim@meyering.net>
10938 Invoke AC_CHECK_FUNCS(getmntent) unconditionally so that tests of
10939 $ac_cv_func_getmntent (e.g., in gl_LIST_MOUNTED_FILE_SYSTEMS) need
10940 not double-quote uses of that variable, to accommodate the rare
10941 case in which getmntent is available in none of the libraries
10942 checked. This happens at least on FreeBSD 5.0.
10944 2006-05-20 Paul Eggert <eggert@cs.ucla.edu>
10946 * lib/autoconf/general.m4 (AC_CONFIG_AUX_DIRS): Bring back
10947 ac_config_guess, ac_config_sub, and ac_configure, since evidently
10948 some other programs unwisely rely on these undocumented vars.
10949 But put in warning comments about them.
10950 Problem reported by Ralf Wildenhues in
10951 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00068.html>.
10952 * NEWS: Document that these variables are intended to go away.
10954 2006-05-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10956 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): Require AC_PROG_CXX,
10957 and set the language to C++ (analogous to the equivalent Fortran
10960 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): New macro.
10961 * doc/autoconf.texi (C++ Compiler): Document it.
10962 * lib/autoconf/fortran.m4 (_AC_PROG_FC_C_O): Adjust comment.
10965 2006-05-19 Paul Eggert <eggert@cs.ucla.edu>
10967 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Fix off-by-one bug
10968 that caused config.status to generate 100-command sed scripts; the
10969 portable limit is 99.
10971 2006-05-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10973 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Name temporary
10974 variable `ac_d' instead of `d' to avoid infringing namespace.
10975 Report by Ralf Menzel.
10977 2006-05-18 Paul Eggert <eggert@cs.ucla.edu>
10979 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Don't prepend
10980 $ac_top_build_prefix to $MKDIR_P if it's just 'mkdir -p'.
10981 * tests/tools.at (autoconf: subdirectories): New test, taken from
10982 the corresponding problem report by Ralf Wildenhues in:
10983 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00053.html
10985 * lib/autoconf/functions.m4 (AC_REPLACE_FNMATCH, AC_FUNC_FNMATCH_GNU):
10986 Quote some uses of shell variables if they might suffer unexpected
10987 globbing. This doesn't fix all instances of quoting problems that
10988 I found, just the easy ones that look safe.
10989 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR, _AC_INIT_HELP):
10990 (AC_CONFIG_AUX_DIR, AC_CONFIG_AUX_DIR_DEFAULT, AC_CONFIG_AUX_DIRS):
10991 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST, AC_CANONICAL_TARGET):
10992 (AC_CACHE_LOAD, AC_CACHE_SAVE): Likewise.
10993 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF, _AC_PATH_X_DIRECT): Likewise.
10994 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Likewise.
10995 * lib/autoconf/status.m4 (_AC_OUTPUT_LINK, _AC_OUTPUT_SUBDIRS):
10997 * lib/autotest/general.m4 (_AC_INIT_PARSE_ARGS): Likewise.
10998 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Likewise.
11000 2006-05-18 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11002 * bin/autoreconf.in ($help): Reword according to the manual.
11003 Suggested by Olly Betts.
11005 2006-05-17 Olly Betts <olly@survex.com> (tiny change)
11006 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11008 * bin/autoreconf.in: Pass the directory argument to
11009 `require_configure_ac'. Fix comment.
11010 * tests/torture.at (Configuring subdirectories): Expose this.
11011 Reported by Olly Betts.
11013 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11015 * lib/Automake/Configure_ac.pm, lib/Automake/Channels.pm,
11016 lib/Automake/FileUtils.pm, lib/Automake/Struct.pm: Sync from
11017 Automake as follows:
11019 * lib/Autom4te/Configure_ac.pm (find_configure_ac): Use
11020 `$configure_in' instead of `configure.in', to preserve
11021 directory component.
11023 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11025 * config/config.guess, config/config.sub, config/texinfo.tex,
11026 doc/make-stds.texi, doc/standards.texi: Sync from upstream.
11028 2006-05-14 Paul Eggert <eggert@cs.ucla.edu>
11030 * lib/autoconf/headers.m4 (AC_HEADER_STDBOOL): Fix overly-picky
11031 test for C99 conformance; (bool) 0.5 is an integer constant
11032 expression, but (bool) -0.5 is not. Problem reported by Fedor
11033 Sergeev in <http://forum.sun.com/jive/thread.jspa?threadID=96202>.
11035 2006-05-13 Paul Eggert <eggert@cs.ucla.edu>
11037 * doc/autoconf.texi (Particular Programs): AC_PROG_MKDIR_P now
11038 sets MKDIR_P, not mkdir_p, to avoid collisions with Automake.
11039 Warn about obsolete install-sh files. Remove stray sentence
11040 fragment and fix cross reference.
11041 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Don't insist on
11042 install -d; this undoes the 2006-05-10 change.
11043 (MKDIR_P): Mark with AN_MAKEVAR.
11044 (AC_PROG_MKDIR_P): Fall back on $ac_install_sh, not $INSTALL, so
11045 that we don't require $INSTALL to be thread-safe. Move comments
11046 out of generated code. Require AC_CONFIG_AUX_DIR_DEFAULT instead
11047 of AC_PROG_INSTALL. Output a message saying that we're checking
11048 mkdir -p. Set MKDIR_P rather than mkdir_p. Do special magic for
11049 MKDIR_P instead of AC_SUBST.
11050 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE, _AC_OUTPUT_CONFIG_STATUS):
11051 Special magic for MKDIR_P, too.
11052 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Remove comment that defeated
11054 * tests/local.at (AT_CHECK_ENV): mkdir_p -> MKDIR_P.
11056 2006-05-11 Paul Eggert <eggert@cs.ucla.edu>
11058 Sync from Automake, as follows:
11060 2006-05-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11061 * config/install-sh: Initialize IFS, so field splitting isn't
11063 * config/mkinstalldirs: Likewise.
11064 * config/missing: Remove superfluous quotes. Replace all uses of
11065 `[' by `test', for consistency, and for..
11066 * config/missing (sed_minuso, sed_output): New variables.
11067 (autom4te, help2man, makeinfo): Use them. Unifies detection of
11068 `-o FILE', `--output FILE', `--output=FILE', stricter regex.
11069 Fixes `missing' to detect `--output' for help2man. Fixes
11070 PR automake/483. Report by Dennis J. Linse.
11071 (autom4te): Document in `missing --help'.
11073 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
11075 * NEWS: New macro AC_PROG_MKDIR_P. AS_MKDIR_P is now more robust.
11076 * config/install-sh: Don't use 'path' to talk about file names,
11077 as per GNU coding standards. Close a race condition reported by Ralf
11078 Wildenhues and Stepan Kasal. There is still a race condition
11079 on hosts that predate Posix 1003.1-1992, but we can't help this.
11080 Don't mishandle weird characters like space on pre-Posix hosts.
11081 Invoke mkdir at most once per dir arg on pre-Posix hosts.
11082 * doc/autoconf.texi (Programming in M4sh): Cross-reference to
11083 AC_PROG_MKDIR_P from AS_MKDIR_P.
11084 (Limitations of Usual Tools): Cross-reference to AC_PROG_MKDIR_P
11085 from mkdir. Mention that Autoconf 2.60 install-sh is safe but
11086 earlier editions are not (including Automake 1.8.3).
11087 Do not suggest mkinstalldirs for thread-safety.
11088 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Insist on an 'install'
11089 that understands -d, so that AC_PROG_MKDIR_P can fall back on $INSTALL.
11090 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Make it more robust in the
11091 presence of special characters and race conditions.
11092 * tests/local.at (AT_CHECK_ENV): Add mkdir_p to the list of variables
11093 in Autoconf's name space.
11095 2006-05-10 Bruno Haible <bruno@clisp.org>
11096 and Paul Eggert <eggert@cs.ucla.edu>
11098 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): New macro, taken
11099 from Automake with minor changes.
11100 * doc/autoconf.texi (Particular Programs): Document AC_PROG_MKDIR_P.
11102 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
11104 * config/install-sh: Update to Automake CVS version, as follows:
11105 2006-04-25 Stepan Kasal <kasal@ucw.cz>
11106 * lib/install-sh: Simplify the expr implementation of dirname.
11107 2006-04-24 Paul Eggert <eggert@cs.ucla.edu>
11108 * lib/install-sh: Handle --, and diagnose unknown options.
11110 2006-05-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11112 * tests/Makefile.am (AUTOTEST): Use `$(MY_AUTOM4TE)' instead of
11113 `./autom4te' to create `./testsuite', since the `all' target
11114 will ensure its presence, but `installcheck' should not create
11115 the uninstalled wrappers.
11117 * tests/torture.at (Unusual Automake input files): Skip if we
11118 detect automake < 1.8.
11120 2006-05-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11122 * lib/autoconf/c.m4 (AC_PROG_CC_STDC): If ac_cv_prog_cc_stdc
11123 is set to `no', then that overrides and sets ac_cv_prog_cc_c89
11124 and ac_cv_prog_cc_c99 to `no', for backward compatibility.
11127 2006-05-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11129 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Take care not to
11130 munge (multiple) white space and other oddities.
11131 * tests/torture.at (AT_CHECK_AC_ARG_VAR): Make sure to M4-escape
11132 single quotes in variable assignment.
11133 (AC_ARG_VAR, configure invocation): Adjust tests to expose this
11134 and similar failures by adding multiple spaces, tabs, and other
11135 special characters.
11136 Report and different test suggested by Francesco Romani
11137 <fromani@gmail.com> and Andrew Church <achurch@achurch.org>.
11139 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): When we escape
11140 single quotes, we only need to search for single quotes; this
11141 both simplifies the search pattern, and makes us less
11142 susceptible to `echo' variations for arguments not containing
11144 (_AC_ARG_VAR_VALIDATE): Likewise.
11146 2006-05-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11148 * doc/autoconf.texi (Special Shell Variables) <IFS>: Document
11149 `$*' and IFS concatenation issue with traditional shells and
11150 bash-2.04. Report by Seanster@Seanster.com.
11152 2006-05-03 Bruno Haible <bruno@clisp.org>
11154 * doc/autoconf.texi (Limitations of Usual Tools): Identify more

11172 traditional shells like the Solaris one that do not use the
11173 first IFS character for assembling `$*'.
11174 Prompted by a related report from autoconf_bug@nro.ca.
11176 2006-05-01 Paul Eggert <eggert@cs.ucla.edu>

11232 2006-04-25 Paul Eggert <eggert@cs.ucla.edu>
11234 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Don't use AS_ERROR,
11235 since as_me isn't set yet.
11237 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
11239 Prepare for deprecation of AS_BASENAME and AS_DIRNAME, and fix
11240 a few minor bugs in this area.
11242 * doc/autoconf.texi (Programming in M4sh): Comment out the
11243 documentation of AS_BASENAME, for now.
11244 (Shell Substitutions): Do not use AS_DIRNAME in an example.
11245 (Limitations of Builtins) <basename>: Do not refer to
11247 * bin/autoconf.as (me): Don't use AS_BASENAME.
11248 (dir): Remove the unused variable.
11249 * lib/m4sugar/m4sh.m4 (_AS_DETECT_REQUIRED): Renamed from
11250 AS_DETECT_REQUIRED. All uses changed.

11269 * lib/autoconf/general.m4: Likewise.
11270 * lib/autoconf/headers.m4: Likewise.
11272 * doc/autoconf.texi (Run Time): Document the exit status situation
11273 with more accuracy and detail.
11275 2006-04-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11277 * doc/autoconf.texi (Introduction): The GNU Autoconf Macro
11278 Archive is not officially `GNU' any more. Update URL.
11279 (Defining Directories): Likewise
11280 * lib/autoconf/c.m4 (AC_C_RESTRICT): Update URL.
11282 2006-04-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11284 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Remove the leading
11285 newline from the `trap' code to finish `config.log'; the NetBSD
11286 /bin/sh resets the exit status after an empty command, as
11287 documented in doc/autoconf.texi.
11288 Reported by Dalibor Topic <robilad@kaffe.org>.
11290 2006-04-19 Paul Eggert <eggert@cs.ucla.edu>
11292 * doc/autoconf.texi (C Compiler): Clarify AC_C_TYPEOF.
11293 Suggested by Bruno Haible.
11295 2006-04-18 Paul Eggert <eggert@cs.ucla.edu>
11297 * configure.ac (ac_cv_sh_n_works): Don't try to test for it, since
11298 some shells (e.g., Solaris 8 /bin/sh) implement it verrrry slowly.
11299 Instead, just list the shells that we know work.
11300 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Remove 2nd arg. All uses
11301 changed. Be more cautious about the _cv_ variable.
11302 * tests/tools.at (Syntax of the shell scripts): Check the
11303 _cv_ variable once, at first, to avoid an internal autoconf error
11304 when sh -n does not work.
11306 2006-04-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11308 * lib/Autom4te/FileUtils.pm: Sync from Automake.
11310 2006-04-16 Paul Eggert <eggert@cs.ucla.edu>
11312 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Don't
11313 use ">&-" since we're only 99.999% sure that this is portable,
11314 and since the MinGW bug is fixed in a different way.
11315 * lib/autotest/general.m4 (AT_INIT): Likewise.
11317 2006-04-16 Stepan Kasal <kasal@ucw.cz>
11319 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Handle --recheck
11320 before opening config.log, to avoid hitting a bug on MinGW.
11322 2006-04-14 Paul Eggert <eggert@cs.ucla.edu>
11324 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Close
11325 AS_MESSAGE_LOG_FD before reopening it onto the log file.
11326 This works around a MinGW bug reported by Eric Paire.
11327 Make sure that all writes to the log file append to it,
11328 rather than possibly losing data.
11329 * lib/autotest/general.m4 (AT_INIT): Likewise.
11331 2006-04-14 Stepan Kasal <kasal@ucw.cz>
11333 * lib/Autom4te/FileUtils.pm (find_file): Fix a typo in the
11336 2006-04-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11340 * configure.ac (AC_INIT): Bump to 2.59d.
11342 2006-04-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11346 * Makefile.maint (news-date-check): Do not require a leading `*'
11347 before the release date in NEWS.
11349 2006-04-12 Stepan Kasal <kasal@ucw.cz>
11350 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11352 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If the templates for
11353 the instantiated file do not contain the string 'datarootdir'
11354 but contain @datadir@, @docdir@, @infodir@, @localedir@, or
11355 @mandir@, replace the reference '${datarootdir}' by the value.
11356 * tests/torture.at (datarootdir workaround): New test.
11357 * NEWS: Advertise this temporary fixup.
11358 Based on a patch by Bruno Haible, reported and analyzed by
11359 Paul Eggert and Noah Misch.
11361 2006-04-12 Eric Blake <ebb9@byu.net>
11363 * tests/autotest.at (Debugging a failed test): Fix comment.
11365 2006-04-12 Stepan Kasal <kasal@ucw.cz>
11367 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): Simplify the summary of
11368 all the changes since 2006-04-07.
11370 2006-04-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11372 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): If `ln -s file1 file2'
11373 succeeded, but `ln -s file dir' failed, take care to remove the
11374 leftover target before the next test, to prevent its spurious
11375 failure; also make sure `ln file dir' works before selecting it.
11376 Thanks to Keith Marshall for pointing this out.
11379 * lib/autotest/general.m4 (AT_INIT): Store quoted variable
11380 assignments in `at_debug_args', so that we put them correctly
11381 in the `run' script.
11382 * tests/autotest.at (Debugging a failed test): Unmark XFAIL.
11383 Reported by Eric Blake.
11385 2006-04-11 Eric Blake <ebb9@byu.net>
11387 * tests/autotest.at (AT_CHECK_AT): Add new argument, to allow
11388 top-level tests after micro-suite has been run. Used in...
11389 (Debugging a successful test, Debugging script and environment),
11390 (Debugging a failed test): ...these new tests. The first of these
11392 * lib/autotest/general.m4 (_AT_CREATE_DEBUGGING_SCRIPT): New
11393 macro, split out from...
11394 (AT_INIT): ...here, so that using -d also generates a run script.
11395 Document that -d inhibits top-level logging.
11396 * doc/autoconf.texi (testsuite Invocation): Document that -d only
11397 inhibits top-level logging; debug scripts are created.
11399 * lib/autotest/general.m4 (_AT_CHECK): Avoid syntax error on empty
11401 * tests/autotest.at (Empty test, Empty check): New test to check it.
11403 * lib/autoconf/c.m4 (AC_C_CONST, AC_C_VOLATILE): Avoid warnings
11406 2006-04-10 Stepan Kasal <kasal@ucw.cz>
11408 * tests/mktests.sh: Use "trap '' 0", not "trap 0". Do not touch
11409 the files if a problem appears. Make the empty *.at files
11410 read-only, too. Proposed by Ralf Wildenhues.
11412 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11414 * config/Makefile.am: Add comment to force updated Makefile.in.
11416 * lib/freeze.mk: Fix typo in comment. Unlike the last, white
11417 space only patch to this file, this patch causes the Makefile.in
11418 files that include freeze.mk to be updated, and thus have a
11419 newer time stamp again, which in turn makes a pristine CVS
11420 checkout have correct time stamps.
11422 * Makefile.maint (cvs-sv): New macro, to be used..
11423 (config.guess-url_prefix, config.sub-url_prefix)
11424 (texinfo.tex-url_prefix, standards.texi-url_prefix): ..here;
11425 point to CVS text checkout of Gnulib files.
11426 (copyright-check): Bump current year.
11427 (announcement): Do not hard-wire `./announce-gen'.
11428 (cvs-update): Propagate failures of `cvs' and `move-if-change'
11430 * Makefile.cfg (executable-update): Use `chmod a+x' instead of
11432 (wget_files): Update config.guess, config.sub, texinfo.tex by
11433 `wget-update', now that their URLs work again.
11435 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
11437 * doc/autoconf.texi (Particular Types): Don't use AC_CHECK_TYPE.
11438 Problem noted by Paul D. Smith.
11440 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11442 * doc/autoconf.texi: Remove unused words from word list.
11443 * .x-sc_prohibit_atoi_atof, .x-sc_space_tab, .x-sc_sun_os_names,
11444 .x-sc_trailing_space: New files.
11446 * doc/standards.texi: Sync from gnulib.
11448 * NEWS, doc/autoconf.texi (AC_LIBOBJ vs LIBOBJS): Mark
11449 `LIBOBJDIR' as experimental.
11451 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): MSYS `ln -s' fails
11452 with a target directory; it's internally implemented as `cp'
11453 anyway, but since Autoconf advertises the possibility to use
11454 a target directory when LN_S is `ln -s', we need to find out.
11455 Reported by Rolf Ebert <rolf.ebert.gcc@gmx.de> against MSYS,
11456 analyzed by Keith Marshall <keith.marshall@total.com>.
11460 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
11462 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Just output
11463 confdefs.h as-is. In general, if it has backslash-newline or the
11464 like, then it doesn't work either to sort or to remove empty
11467 2006-04-09 Stepan Kasal <kasal@ucw.cz>
11469 * tests/Makefile.am (AUTOCONF_FILES): Fix typo in the comment.
11471 2006-04-09 Alexandre Duret-Lutz <adl@gnu.org>
11473 * lib/autom4te.in (Automake-preselections): Preselect
11476 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>
11478 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Use '\'' for an
11479 apostrophe within a single-quoted string, as this is the usual
11480 tradition and is easier to read than '"'"'. Don't rely on the
11481 shell treating "$/" like '$/'. Use a more-consistent indenting
11482 style for the trap.
11484 2006-04-09 Eric Blake <ebb9@byu.net>
11486 * tests/autotest.at (Backquote command substitution),
11487 (Multiline backquote command substitution): Remove mistaken
11488 AT_NO_CMDSUBST from the 2006-03-14 patch, which was meant to be
11490 (Parenthetical command substitution, Multiline parenthetical
11491 command substitution): here.
11493 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>
11495 Import macros from gnulib (often changing their name).
11497 * NEWS: AC_C_TYPE_LONG_DOUBLE is now obsolete.
11498 New macros AC_CHECK_DECLS_ONCE, AC_CHECK_FUNCS_ONCE,

11509 (Pointers): Add Gnulib URL.
11510 (Particular Functions): Alphabetize. Add AC_FUNC_STRTOLD.
11511 (Generic Functions): Add AC_CHECK_FUNCS_ONCE. Refer to new
11513 (Particular Headers): Add AC_HEADER_ASSERT. For stdbool.h,

11517 (Generic Declarations): Add AC_CHECK_DECLS_ONCE.
11518 (Particular Structures): Add AC_STRUCT_DIRENT_D_INO,

11523 AC_TYPE_INTMAX_T, AC_TYPE_INTPTR_T, AC_TYPE_LONG_DOUBLE,
11524 AC_TYPE_LONG_DOUBLE_WIDER, AC_TYPE_LONG_LONG_INT, AC_TYPE_UINT8_T,
11525 AC_TYPE_UINT16_T, AC_TYPE_UINT32_T, AC_TYPE_UINT64_T,
11526 AC_TYPE_UINTMAX_T, AC_TYPE_UINTPTR_T, AC_TYPE_UNSIGNED_LONG_LONG_INT.
11527 (C Compiler): Move AC_C_LONG_DOUBLE to ...
11528 (Obsolete Macros): here. Under AC_LONG_DOUBLE, mention
11529 AC_TYPE_LONG_DOUBLE or AC_TYPE_LONG_DOUBLE_WIDER instead.
11530 (Posix Variants): Add AC_USE_SYSTEM_EXTENSIONS.
11531 (Coding Style). Don't mention m4_expand_once.
11532 * lib/autoconf/c.m4 (AC_C_LONG_DOUBLE): Implement via

11539 * lib/autoconf/headers.m4 (AC_CHECK_HEADERS_ONCE): New macro.
11540 (AC_HEADER_ASSERT): New macro.
11541 (AC_HEADER_STDBOOL): Don't assume "#error" works.
11542 Catch a bug in IBM AIX xlc compiler version 6.0.0.0.
11543 Catch a bug in an HP-UX C compiler.
11544 * lib/autoconf/specific.m4 (AC_USE_SYSTEM_EXTENSIONS): New macro.

11552 * tests/mktests.sh (ac_exclude_list, au_exclude_list): Do not
11553 use /^foo|bar$/, it does not mean /^(foo|bar)$/.
11555 2006-04-08 Stepan Kasal <kasal@ucw.cz>
11557 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Fix the wording
11558 of the warning introduced by the 2001-08-28 change.
11560 2006-04-08 Stepan Kasal <kasal@ucw.cz>,
11561 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11563 * lib/autoconf/general.m4 (AC_CACHE_SAVE): All `ac_cv_env_foo'
11564 variables shall be overriden by the cache.
11565 * tests/torture.at (AC_ARG_VAR): Test also with a first value
11566 that contains braces.
11568 2006-04-07 Stepan Kasal <kasal@ucw.cz>
11570 Revert the patch from 2006-04-01 and only improve
11571 _AS_DETECT_BETTER_SHELL:
11573 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Do not optimize; do not
11574 skip nonexistent directories.
11575 (_AS_DETECT_BETTER_SHELL): The optimization is moved here--try
11576 only shell candidates which exist.
11577 (AS_UNAME): No need to give three parameters to _AS_PATH_WALK.
11578 * lib/autotest/general.m4 (AT_INIT): No need to give three

11590 2006-04-07 Stepan Kasal <kasal@ucw.cz>
11592 Revert my change from 2006-03-17, in other words:
11593 * lib/m4sugar/m4sh.m4 (AS_BOURNE_COMPATIBLE): Insert BIN_SH=xpg4
11595 (AS_SHELL_SANITIZE): Remove DUALCASE=1.

11626 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): Fix the detection of
11627 whether `set' quotes correctly: redirect stderr of the tested
11628 `set', and use a subshell, for Ultrix; use `sed' instead of
11629 `grep' for zsh `set' which may write binary output; match only
11630 at the beginning of a line, to avoid false positives.
11631 In order to avoid false positives by unrelated variables with
11632 multiline content, put the dump algorithm in a subshell and
11633 unset all variables containing newlines (except some which are
11634 special to the shell). Warn about cache variables that are

11640 Sync from upstream.
11642 * tests/mktests.sh: Reword comments.
11644 * tests/mktests.sh: Only skip internal macros starting with
11645 `_AC_' or `__AC_'. Noted by Stepan Kasal.
11646 Update exclusion lists for the test suite to this end:
11647 (AC_ARG_VAR): Do test this now.

11681 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_LINKS):
11682 (AC_CONFIG_COMMANDS): Do not do so here.
11683 (_AC_CONFIG_REGISTER_DEST): Double quote the tags in macros _AC_LIST_TAGS
11684 and_AC_LIST_TAG_COMMANDS; fixes another regression introduced by the
11685 2005-07-25 rewrite. Noticed by Noah Misch.
11687 * lib/autoconf/general.m4 (AC_PRESERVE_HELP_ORDER): Do not define

11691 * lib/autoconf/general.m4 (AC_ARG_VAR): Do not use m4_divert_once

11695 for --help from Cygnus `configure.'
11697 2006-04-06 Paul Eggert <eggert@cs.ucla.edu>

11739 normalizing it, consistent it with previous releases.
11740 * tests/torture.at (Macro calls in AC_CONFIG_COMMANDS tags): New test.
11742 2006-04-05 Paul Eggert <eggert@cs.ucla.edu>

11750 Prefer 'sort -u' to 'sort | uniq'. Filter data before sorting it.
11751 Use 'comm' rather than N instances of grep; this also fixes a bug
11752 whereby substrings were incorrectly matched, causing us to not
11753 generate tests for AC_F77_NAME_MANGLING and AC_FUNC_LSTAT.
11754 (exclude_list): Exclude empty macros.

11838 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't try to
11839 detect exeext, it will be done by _AC_COMPILER_EXEEXT_O; just set

11841 _AC_COMPILER_EXEEXT_WORKS. Move the definition of ac_files and the
11842 initial `rm' of the candidate files...
11843 (_AC_COMPILER_EXEEXT): ... here and simplify them. Moreover, use
11844 the same list in subsequent `rm' calls, and for the temporary
11845 redefinition of ac_clean_files; call _AC_COMPILER_OBJEXT at the end,
11846 and don't call the other _AC_COMPILER_EXEEXT_* macros directly, use...
11847 (_AC_COMPILER_EXEEXT_TESTS): ... this new macro.
11848 (_AC_COMPILER_EXEEXT_O): Don't export ac_cv_exeext, it's not needed (or
11849 no longer needed) by libtool. Make it a cache check.
11850 (_AC_COMPILER_EXEEXT_CROSS): Remove the comment, it was obviously
11851 copied here by mistake.

12510 2005-12-29 Paul Eggert <eggert@cs.ucla.edu>
12512 * doc/autoconf.texi (Shell Substitutions): Warn about unbalanced

12546 CONFIG_SHELL in the environment of the configure rerun.
12547 * doc/autoconf.texi (Here-Documents, config.status Invocation):
12548 Suggest passing CONFIG_SHELL absolute, and in the environment
12549 rather than as option.

12553 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE):

12569 * lib/autoconf/programs.m4 (AC_CHECK_PROG, AC_PATH_PROG):
12570 Factor functionality to..
12571 (_AC_CHECK_PROG, _AC_PATH_PROG): these new macros, but only
12572 `AC_SUBST($1)' in the public version.
12573 (AC_CHECK_TOOL, AC_PATH_TOOL, AC_PATH_TARGET_TOOL)
12574 (AC_CHECK_TARGET_TOOL): Use internal versions for ac_ct_* and
12577 2005-11-01 Stepan Kasal <kasal@ucw.cz>
12579 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Remove the comment about 8+3

12594 conftst2.$ac_objext.
12595 * lib/autoconf/fortran.m4 (_AC_PROG_FC_C_O): Likewise.
12597 2005-10-24 Stepan Kasal <kasal@ucw.cz>
12599 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Use conftst2.o instead of
12600 conftest.o, to see whether the compiler really obeys; rm the object
12601 file before and after the test and register it with ac_clean_files.
12602 * lib/autoconf/fortran.m4 (_AC_PROG_FC_C_O): Likewise.
12604 2005-10-21 Stepan Kasal <kasal@ucw.cz>
12606 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): When determining,
12607 the delimiter CEOF$ac_eof: fix quoting of CEOF[0-9]* and modify the

12622 2005-10-19 Paul Eggert <eggert@cs.ucla.edu>
12624 * doc/autoconf.texi (Generating Sources): AC_LANG_PROGRAMS ->
12625 AC_LANG_PROGRAM, fixing a typo. Don't give details about
12626 the inner workings of AC_LANG_FUNC_LINK_TRY.
12627 * lib/autoconf/c.m4 (AC_LANG_CALL(C)): Reformat to match
12628 AC_LANG_FUNC_LINK_TRY. This involves returning the value returned
12629 by the function rather than ignoring it.
12630 (AC_LANG_FUNC_LINK_TRY(C)): Call the function rather than simply
12631 comparing its address. Intel's interprocedural optimization was
12632 outsmarting the old heuristic. Problem reported by
12635 2005-10-19 Stepan Kasal <kasal@ucw.cz>
12637 * lib/autoconf/general.m4 (AC_SUBST): Remove an obsolete comment.

12644 2005-10-04 Stepan Kasal <kasal@ucw.cz>
12646 * lib/autotest/general.m4 (AT_INIT): Really make the subtree writable
12647 before removing it (chmod -R u+rwx); there are three instances of this.
12649 2005-10-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
12650 Stepan Kasal <kasal@ucw.cz>
12652 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Balance parentheses.
12653 * lib/autotest/general.m4 (AT_INIT): If the test dir already exists,
12654 make its content writable before removing it. Remove an errorneous
12655 comment from the end, where the logs of the failed tests are copied
12656 to the main log file.
12658 2005-09-27 Stepan Kasal <kasal@ucw.cz>
12660 * tests/semantics.at (AC_C_BIGENDIAN): Pass --force to autoheader,
12661 in case the computer is too quick. Double quote the configure.ac
12664 * tests/local.at (AT_CHECK_AUTOCONF): Always pass --force to prevent
12665 problems if the testsuite were running too fast.
12667 2005-09-18 Paul Eggert <eggert@cs.ucla.edu>
12669 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Look for X11/Xlib.h
12670 and XrmInitialize rather than X11/Intrinsic.h and XtMalloc
12671 (which belong to Xt, not X itself). See Debian bug 327655.
12672 * NEWS: Mention this.
12674 2005-09-07 Stepan Kasal <kasal@ucw.cz>
12676 * lib/autoconf/c.m4 (AC_LANG_SOURCE(C)): Remove an incorrect comment.
12678 2005-09-06 Paul Eggert <eggert@cs.ucla.edu>
12680 * config/move-if-change: Don't output "$2 is unchanged";
12681 suggested by Ben Elliston. Handle weird characters correctly.
12683 2005-09-06 Stepan Kasal <kasal@ucw.cz>
12685 * lib/autoconf/libs.m4 (AC_SEARCH_LIBS): Merge the two AC_LINK_IFELSE
12686 calls, so that the final expansion of this macro is shorter.
12687 Create the conftest.$ac_ext outside the `for' loop, to speed the run.
12688 Do not use `break' in the argument to AC_LINK_IFELSE, it would skip
12689 the cleanup there. Use AS_VAR_* macros, to be more general.
12690 * tests/semantics.at (AC_SEARCH_LIBS): Check for the cleanup.
12692 * lib/autoconf/general.m4: Use AS_IF where appropriate.
12694 * lib/m4sugar/m4sh.m4 (AS_IF): Use m4_default.
12696 2005-09-01 Stepan Kasal <kasal@ucw.cz>
12698 * doc/autoconf.texi (Configuration Headers): Add an index entry
12701 2005-08-26 Pavel Roskin <proski@gnu.org>
12703 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): Use shell variable

12707 2005-08-26 Paul Eggert <eggert@cs.ucla.edu>
12709 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE):
12710 The previous patch didn't work, so try a better one.
12712 2005-08-26 Stepan Kasal <kasal@ucw.cz>
12714 * doc/autoconf.texi (Programming in M4sh) <AS_TR_CPP>: Fix m4 quoting
12715 in the example. Reported by Bruno Haible.
12716 <AS_TR_SH>: Likewise. Also modify the example to be more convincing:
12717 "if $undefined_var;" succeeds with my shell.
12719 * lib/autoconf/general.m4 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST,
12720 AC_CANONICAL_TARGET): Define by AC_DEFUN, no need to use AC_DEFUN_ONCE;
12721 but change the m4_divert_text to m4_divert_once.
12723 2005-08-25 Paul Eggert <eggert@cs.ucla.edu>
12725 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE):
12726 Work around bug in Solaris /usr/xpg4/bin/awk.
12727 The bug is present in at least Solaris 8 through 10.
12729 2005-08-24 Stepan Kasal <kasal@ucw.cz>
12731 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Simplify; rejecting
12732 some evil values and relying on the fact that $* concatenates the
12733 parameters by the first character from IFS.
12735 2005-08-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
12736 Stepan Kasal <kasal@ucw.cz>
12738 * lib/autoconf/status.m4 (_AC_CONFIG_REGISTER_DEST): When the
12739 first header appears, define AH_HEADER.
12740 * doc/autoconf.texi (Configuration Headers): Document AH_HEADER.
12741 Update limitations about when to call AC_CONFIG_HEADERS.
12742 (Configuration Commands): Document that AC_CONFIG_COMMANDS_PRE
12743 parameter can call AC_SUBST, AC_DEFINE, or AC_CONFIG_FOOS; explain
12744 that AC_CONFIG_COMMANDS_PRE and AC_CONFIG_COMMANDS_POST are not
12745 ``Configuration Actions''; fix their index entries.
12747 * lib/autotest/general.m4 (AT_INIT): Process multiple keywords
12748 options correctly. Process N-M as M-N if M is smaller than N.
12749 Process ranges correctly so that N-N will run only N.
12750 Sort and uniquify the tests that will be run. If there is more
12751 than one test, reinsert the banners for the tests.
12752 * tests/autotest.at (Keywords): Unmark XFAIL.
12754 2005-08-23 Stepan Kasal <kasal@ucw.cz>
12756 * lib/autoconf/general.m4 (_AC_DEFINE_Q): Strip the parameter list
12757 before passing the macro name to AH_TEMPLATE.
12759 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): config.status
12760 now opens log after option processing; in particular, --version
12761 and --help do not touch config.log.
12763 * Makefile.maint: Revert the change from 2005-08-12.
12765 2005-08-22 Stepan Kasal <kasal@ucw.cz>
12767 * lib/autoconf/general.m4 (AC_ARG_ENABLE, AC_ARG_WITH): Factor out

12778 Prepend to LIBS, not append, in examples.
12780 2005-08-16 Stepan Kasal <kasal@ucw.cz>
12782 When building in place, set srcdir="."; suggested by Tim Van Holder.
12784 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Do this; to recognize
12785 build in place, we need ac_pwd, and thus have to AC_REQUIRE ...
12786 (_AC_INIT_DIRCHECK): ... this macro and AC_DEFUN both of them.
12787 * lib/autoconf/status.m4 (_AC_SRCDIRS): Fix a comment: srcdir="."
12788 does not mean "no --srcdir option".
12790 2005-08-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
12792 * tests/autoscan.at (autoscan): New file.
12793 * tests/suite.at: Use it.
12794 * tests/Makefile.am (TESTSUITE_HAND_AT): Add it.
12795 Reported against Libtool by Gideon Go <gideon.go@gmail.com>.
12797 * tests/autotest.at (Keywords): Test keywords combinations.
12799 2005-08-12 Stepan Kasal <kasal@ucw.cz>
12801 * Makefile.maint (GZIP_ENV): When checking the help text of gzip,
12802 add "2>&1"; gzip 1.2.4 prints help on stderr.
12804 2005-07-27 Stepan Kasal <kasal@ucw.cz>
12806 * lib/autotest/general.m4 (_AT_DECIDE_TRACEABLE): The symbol at_reason
12807 was pushdef'ed twice while popped only once. Push it only once.
12808 (_AT_CHECK): Cosmetic changes to the "case $at_status" command.
12810 2005-07-26 Stepan Kasal <kasal@ucw.cz>
12812 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): The message is now

12815 2005-07-25 Paul Eggert <eggert@cs.ucla.edu>
12817 * Makefile.maint: Update from Bison.
12819 * lib/m4sugar/m4sugar.m4 (m4_strip): Comment fix---change tab to
12820 "<tab>" in comment, so that the point is understandable.
12822 2005-07-25 Stepan Kasal <kasal@ucw.cz>
12824 Rewrite substantial part of lib/autoconf/status.m4.
12825 The main change is that CONFIG_FILES, CONFIG_HEADERS, CONFIG_LINKS,
12826 and CONFIG_COMMANDS are not processed in four separate loops.
12827 Instead, there is one main loop. This alows that the common code
12828 is expanded only once, thus config.status (and configure) is smaller.
12830 The registration mechnism in AC_CONFIG_FILES and cousins also changed;
12831 the AC_LIST_FILES and cousins macros are no longer used.
12833 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES, _AC_OUTPUT_HEADERS,
12834 _AC_OUTPUT_LINKS, _AC_OUTPUT_COMMANDS): Renamed to ...
12835 (_AC_OUTPUT_FILE, _AC_OUTPUT_HEADER, _AC_OUTPUT_LINK,
12836 _AC_OUTPUT_COMMAND): ..., respectively. These macros no longer
12837 contain the initialization, nor the for loop, nor the associated
12838 commands; all these go to ...
12839 (_AC_OUTPUT_MAIN_LOOP): ... this new macro, called from
12840 _AC_OUTPUT_CONFIG_STATUS.
12841 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST, _AC_CONFIG_SPLIT_FILE_IN):
12842 Nuked; the code was merged into _AC_OUTPUT_MAIN_LOOP.
12843 (_AC_OUTPUT_FILE): The creation of the sed script ...
12844 (AC_OUTPUT): ... and the setup of ac_vpsub goes to ...
12845 (_AC_OUTPUT_FILES_PREPARE): ... a new macro, also called from
12846 _AC_OUTPUT_MAIN_LOOP.
12847 (_AC_CONFIG_FILES, _AC_CONFIG_HEADERS, _AC_CONFIG_LINKS,
12848 _AC_CONFIG_COMMANDS): Use ...
12849 (_AC_CONFIG_FOOS): ... this new macro, which uses these ...
12850 (_AC_CONFIG_REGISTER, _AC_CONFIG_REGISTER_DEST): ... new macros.
12851 (_AC_CONFIG_FILE, _AC_CONFIG_HEADER, _AC_CONFIG_LINK,
12852 _AC_CONFIG_COMMAND, _AC_CONFIG_DEPENDENCIES): No longer needed.
12853 (_AC_CONFIG_DEPENDENCY): Update, it uses these ...
12854 (_AC_CONFIG_DEPENDENCY_DEFAULT, _AC_FILE_DEPENDENCY_TRACE_COLON):
12856 (_AC_CONFIG_UNIQUE): Update.
12857 (AC_LIST_FILES, AC_LIST_HEADERS, AC_LIST_LINKS, AC_LIST_COMMANDS):
12858 Replaced by this ...
12859 (_AC_LIST_TAGS): ... new common macro.
12860 (AC_LIST_FILE_COMMANDS, AC_LIST_HEADER_COMMANDS, AC_LIST_LINK_COMMANDS,
12861 AC_LIST_COMMAND_COMMANDS): Replaced by this ...
12862 (_AC_LIST_TAG_COMMANDS): ... new common macro.
12863 (_AC_CONFIG_COMMANDS_INIT): Moved top to the `registration' section;
12864 this didn't belong to the `config commands' section.
12865 (_AC_OUTPUT_COMMANDS_INIT): Don't initialize, m4_ifdef is our friend.
12866 (AC_CONFIG_COMMANDS_PRE, AC_OUTPUT_COMMANDS_PRE,
12867 AC_CONFIG_COMMANDS_POST): Moved to a new section, these didn't belong
12868 to the `config commands' section either.
12869 (AC_CONFIG_SUBDIRS): Don't touch diversion DEFAULTS.
12870 (_AC_LIST_SUBDIRS): Don't initialize, m4_ifdef is our friend.
12872 ... and many changes to the comments nearby.
12874 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): At the end of the day,
12875 set ac_subdirs_all='_AC_LIST_SUBDIRS'.
12876 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
12877 AC_CONFIG_COMMANDS(command:input,...) is no longer allowed.
12878 (#define header templates): The comment at the top of the generated
12879 header now includes the name(s) of the source file(s).
12881 Several unrelated small changes:
12883 * lib/autoconf/general.m4 (AC_CACHE_VAL): Be didactic, quote the first
12884 parameter to AC_DIAGNOSE.
12885 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS): Likewise.
12886 (_AC_LINK_FILES_CNT): Don't AU_DEFUN this; it causes confusing messages
12887 with autoupdate; use m4_define_default inside AU_DEFUNed AC_LINK_FILES.
12888 (AC_OUTPUT): In the compatibility code, use m4_ifvaln, to be consistent
12889 with AU::AC_OUTPUT.
12890 (AU::AC_OUTPUT): Don't double-quote $2 and $3, the compatibility code
12891 in AC_OUTPUT doesn't double-quote it either.
12892 * tests/tools.at (autoupdate): AU::AC_OUTPUT no longer double-quotes the
12895 2005-07-10 Stepan Kasal <kasal@ucw.cz>
12897 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Document which
12898 versions of Portland Group compiler produce single- and double-quoted
12899 -cmdline argument. Reported by Steven G. Johnson <stevenj@fftw.org>
12900 and Ole Holm Nielsen <Ole.H.Nielsen@fysik.dtu.dk>.
12902 2005-07-07 Paul Eggert <eggert@cs.ucla.edu>
12904 * tests/local.at (AT_CONFIG_CMP): Ignore lines like "LIBS=''" too.
12905 This is a corrected version of yesterday's patch.
12907 2005-07-07 Stepan Kasal <kasal@ucw.cz>
12909 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Report the full
12910 path, too; insert a "===" to emphasize the line.
12912 * lib/autoconf/general.m4 (AC_CANONICAL_BUILD): Rename
12913 ac_cv_build_alias to ac_build_alias.
12914 (AC_CANONICAL_HOST, AC_CANONICAL_TARGET): Simplify.
12916 On 2005-02-24, an unintentional AC_SUBST([CC]) was introduced; this
12917 change eliminates it. Problem reported by Alexandre Duret-Lutz.
12918 * lib/autoconf/general.m4 (_AC_ARG_VAR_PRECIOUS): Move the AC_SUBST ...
12919 (AC_ARG_VAR): ... here.
12920 (_AC_INIT_PREPARE): Call AC_SUBST for build_alias, host_alias and
12923 Keep a list of all precious variables and process them with one simple
12924 for loop, instead of expanding all commands, or, OTOH, complicated
12925 processing of output of "set".
12926 * lib/autoconf/general.m4 (_AC_ARG_VAR_PRECIOUS): Acumulate the
12927 variable names in new macro...
12928 (_AC_PRECIOUS_VARS): ... which will be assigned to ac_precious_vars.
12929 (_AC_ARG_VAR_STORE): New macro which writes to diversion PARSE_ARGS
12930 a loop to assign all ac_env_* and ac_cv_env_* variables.
12931 (_AC_ARG_VAR_VALIDATE): Use shell variable ac_precious_vars, divert
12933 (_AC_INIT_DEFAULTS): At the end, if _AC_PRECIOUS_VARS is set, assign
12934 its value to shell variable ac_precious_vars and call
12935 _AC_ARG_VAR_STORE and _AC_ARG_VAR_VALIDATE.
12936 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Don't call
12937 _AC_ARG_VAR_VALIDATE.
12939 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Move AC_LANG_PUSH(C)
12940 and the AC_SUBSTs ...

12958 They are generated by the Tru64 v5.1B shell.
12960 2005-07-05 Stepan Kasal <kasal@ucw.cz>
12962 Fix my changes from 2005-07-01; reported by Noah Misch.
12963 * lib/autoconf/status.m4 (_AC_CONFIG_DEPENDENCIES): Fix the
12964 description, the macro now accepts only a single tag.
12965 (_AC_CONFIG_UNIQUE): Likewise; s/AC_File/[$1]/
12967 Fix cases when the varsions of Autoconf and Autotest don't match.
12968 Reported by Noah Misch.
12969 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Set also
12970 at_top_builddir, for compatibility with older autotest.
12971 * lib/autotest/general.m4 (AT_INIT): If at_top_build_prefix
12972 is not set, use at_top_builddir, for compatibility with older
12973 versions of autoconf.

12977 * bin/autom4te.in ($m4): Catch usages like --nesting-limit=2048.
12978 Problem reported by Patrick Welche.
12980 2005-07-03 Paul Eggert <eggert@cs.ucla.edu>
12982 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Use &, not |, in
12983 sed substitution command, so that we allow | in program prefixes
12984 and program suffixes. (& is a problem anyway; we're not fixing

12987 configure_input, top_builddir, srcdir, etc.
12988 * lib/autotest/general.m4 (AT_INIT): Likewise, for
12989 PATH_SEPARATOR in AUTOTEST_PATH.
12991 2005-07-02 Alexandre Duret-Lutz <adl@gnu.org>
12993 * lib/autoconf/general.m4 (AC_SITE_LOAD): Rewrite the
12994 for loop over config.site files using `set', to allow
12995 directory names containing IFS characters.
12997 2005-07-01 Paul Eggert <eggert@cs.ucla.edu>
12999 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Remove the tests for
13000 directories with weird names. Apparently some people like living
13001 on the edge. However, improve the test that "pwd" actually does
13002 report a name for the working directory.
13003 * NEWS: Remove the claim that we test for funny chars in dir names.
13005 2005-07-01 Stepan Kasal <kasal@ucw.cz>
13007 * lib/autoconf/general.m4 (AC_FOREACH): Make obsolete; it's

13019 (Limitations of Usual Tools) <sed>: Another minor rephrasing.
13021 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Use a here
13022 document to output the default config_* lists to config.status.
13023 Don't recognize option --file, if the functionality is not there.
13024 Likewise for --header; moreover, recognize --he and --h as shortcuts
13025 for --help in that case.
13027 * lib/autoconf/status.m4: Fix the order of the "sections", so that it
13028 matches the order of execution. No code changed.
13030 2005-06-30 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
13032 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Fix also for
13033 single-quoted -cmdline argument in Portland Group compiler.

13047 * lib/autoconf/general.m4 (AC_ARG_VAR): Move next to _AC_ARG_PRECIOUS.
13049 * lib/autoconf/general.m4 (AC_SUBST_TRACE): New macro, to be traced
13050 instead of AC_SUBST; proposed by Alexandre Duret-Lutz.
13051 (AC_SUBST): Call it.
13052 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Call AC_SUBST_TRACE for
13053 the directory specific variables; but don't call it for configure_input.
13055 2005-06-28 Derek Price <derek@ximbiot.com>
13057 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: Reword recent
13060 2005-06-23 Paul Eggert <eggert@cs.ucla.edu>
13062 * NEWS: Don't worry about spaces in bindir etc. Only srcdir and working
13063 directory have inherent problems with special characters like spaces,
13064 due to limitations in Make syntax. Problem reported by Alexandre
13066 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Implement the above.
13067 Also, fix Tru64 porting problem with shell patterns,
13068 reported by Ralf Wildenhues.

13078 Fix some more shell quoting problems. Prompted by a bug report
13079 from Justace Clutter.
13080 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Put name of invalid
13081 variable into diagnostic. Make the diagnostic an error, not a warning,
13082 because we really don't support spaces and suchlike in dir names.
13083 (_AC_INIT_SRCDIR): Allow special characters in $ac_unique_file.
13084 Don't worry about backslashes in srcdir; it can't happen now.
13085 (_AC_INIT_PARSE_ARGS): Allow weird characters in ac_optarg.
13086 Simplify ac_optarg handling.
13087 (_AC_ARG_VAR_VALIDATE): Remove unnecessary and inconsistent quotes.

13094 * tests/local.at (AT_CHECK_ENV): Use $EGREP, not $GREP -E.
13095 (AT_CONFIG_CMP): Use sed instead of grep plumbing.
13097 * doc/autoconf.texi (Limitations of Usual Tools) <grep>: Mention
13098 that '\|' is not allowed in BREs; recommend using newline separated
13099 list of patterns instead of multiple -e options.
13101 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Remove an old comment.
13103 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Use AC_SUBST/2.

13109 2005-06-21 Stepan Kasal <kasal@ucw.cz>
13111 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: Document that
13112 b, t, r, w commands require single space, while : cannot have any.
13113 (Special Shell Variables): Fix sed code this in the example.
13114 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Likewise; and fix a typo.
13115 * lib/autotest/general.m4 (AT_ARG_OPTION): Fix typo in the description.
13117 * lib/m4sugar/m4sugar.m4 (m4_split): If the parameter is empty,
13118 expand to the empty list. Don't use two pairs of m4_changequote,
13119 it's not necessary.
13121 2005-06-20 Derek Price <derek@ximbiot.com>
13123 * lib/m4/programs.m4 (AC_PROG_YACC): Declare YACC & YFLAGS precious.
13125 2005-06-17 Paul Eggert <eggert@cs.ucla.edu>
13127 * lib/m4sugar/m4sh.m4 (as_awk_strverscmp): Port to Solaris /bin/awk.
13128 * doc/autoconf.texi:
13129 Don't mention Solaris versions so much, if a
13130 problem is common to all extant versions of Solaris. Say "SunOS
13131 4" instead of "SunOS" for SunOS 4.
13132 (awk): Mention more of the limitations of traditional Awk.
13133 (cat): Don't talk about cat -v.
13135 2005-06-16 Paul Eggert <eggert@cs.ucla.edu>
13137 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE): New macro.
13138 (AS_VERSION_COMPARE): New macro. The API is taken from CVS,
13139 but the implementation is entirely different and is designed
13140 to be compatible with glibc strverscmp.
13141 * tests/m4sh.at (AS_VERSION_COMPARE): New test.
13143 * doc/autoconf.texi (Limitations of Usual Tools): Mention expr bug

13146 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT):
13147 Use shell builtins rather than 'expr', to work around expr bug.
13149 2005-06-10 Paul Eggert <eggert@cs.ucla.edu>
13151 * doc/autoconf.texi: "filesystem" -> "file system".
13152 "behaviour" -> "behavior".
13153 Warn about \(...\)* in Solaris sed (written by Ralf Menzel).
13154 * lib/autoconf/general.m4: Omit blank after ":" sed command,
13156 * lib/m4sugar/m4sh.m4: Likewise.
13157 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Work around problem
13158 with Solaris sed. Fix by Ralf Menzel and Stepan Kasal.
13160 * man/Makefile.am (MOSTLYCLEANFILES): Add $(srcdir)/*.t.
13161 (.x.1): Ignore the time stamp in the .TH line when deciding whether
13162 to update the man page. That way, we don't have to check in new
13163 man pages every month.
13165 * lib/m4sugar/m4sh.m4 (AS_VAR_TEST_SET): Work even if $1 contains
13166 quotes and backslashes. Patch from Derek Price.

13175 * lib/autotest/general.m4 (AT_INIT): Don't accept Solaris 9's diff
13176 -u, since it outputs chatter if the input files are the same.
13177 Problem reported by Ralf Menzel.
13179 2005-06-08 Derek Price <derek@ximbiot.com>
13181 * lib/m4sugar/m4sugar.m4: Undefine include & sinclude rather than
13182 renaming them since they are about to be redefined anyhow.
13184 2005-06-08 Derek Price <derek@ximbiot.com>
13186 * doc/autoconf.texi (Redefined M4 Macros): Add index entries for most
13187 redefined M4 macros to this node. Document m4_include & m4_sinclude.
13188 Move m4_undefine to alphabetical order.
13190 2005-06-07 Paul Eggert <eggert@cs.ucla.edu>
13192 * README: Recommend GNU M4 1.4.3 or later.
13193 * doc/autoconf.texi (Introduction): Likewise.
13194 Reword to avoid some formatting glitches.
13195 Use "#!/bin/sh", not "#! /bin/sh"; the space isn't needed these days.
13196 Clarify explanation of HP compiler bug.
13197 Redo example output tp match current CVS snapshot.
13198 Use @example.org in email addresses when the examples
13199 might get inadvertently cut-and-pasted into user code.
13200 Remove example of autom4te usage that doesn't seem to work now.
13201 Use modern AC_INIT (except when the example is meant to be
13202 shown with Autoconf 2.13).
13203 Update ksh info for Solaris 9 and later.
13205 Modernize description of Automake versions a bit.
13206 Don't claim a future version of Autoconf is near.
13207 * doc/install.texi: Reword to avoid some formatting glitches.
13209 2005-06-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
13211 * doc/autoconf.texi: Add [] to examples, so that the manual
13212 follows its own advice about quoting better.
13213 Reword to avoid some formatting glitches.
13214 * doc/installt.exi: Reword to avoid some formatting glitches.
13216 * doc/autoconf.texi (Limitations of Builtins) <case>: Mention
13217 Tru64 ksh pattern matching bug. Reported against Libtool by
13218 Albert Chin <libtool@mlists.thewrittenword.com> and
13219 Nicolas Joly <njoly@pasteur.fr>.
13221 2005-06-06 Stepan Kasal <kasal@ucw.cz>
13223 m4_cdr of one-member list was [[]] (one-member list containing an
13224 empty string) instead of [] (an empty list. Callers were skewed to
13225 match this misbehaviour. As a consequence of this:
13226 - m4_foreach([x], [], [foo]) expanded to `foo', while
13227 - the expansion of m4_foreach([x], [[]], [foo]) was empty.
13228 This bug has been fixed:
13230 * lib/m4sugar/m4sugar.m4 (m4_cdr): If only one argument is given,
13231 expand to an empty string; print error msg if called without
13233 (m4_foreach, m4_map, m4_map_sep): Don't expect the previous
13234 misbehaviour; handle [] and [[]] correctly.
13236 2005-06-06 Stepan Kasal <kasal@ucw.cz>
13238 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Nuke ac_max_here_lines.
13239 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Simplify the sed
13240 scripts created and the loop applying them, use _AC_SED_CMD_LIMIT.
13242 2005-06-06 Ralf Menzel <menzel@ls6.cs.uni-dortmund.de> (trivial change)
13244 * doc/autoconf.texi (Limitations of Usual Tools): Solaris' awk cannot
13245 swallow records with more than 99 fields.
13246 * lib/autotest/general.m4 (AT_INIT): Use the awk builtin `split' to
13247 parse the long line.
13249 2005-06-04 Stepan Kasal <kasal@ucw.cz>
13251 * doc/autoconf.texi (Limitations of Usual Tools): AIX awk cannot
13252 swallow literals longer than 399. Reported by Ralf Wildenhues.
13253 * lib/autotest/general.m4 (AT_INIT): Pass $at_groups though stdin,
13254 to workaround this limitation.
13256 2005-06-03 Steven G. Johnson <stevenj@alum.mit.edu>
13258 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Find g95 in addition
13259 to gfortran, and make these the first two compiler names
13260 checked (following the general autoconf preference for gcc).
13262 2005-06-03 Stepan Kasal <kasal@ucw.cz>
13264 * tests/Makefile.am (check_SCRIPTS): Set to $(wrappers).
13265 (DISTCLEANFILES): Remove $(check_SCRIPTS).

13268 2005-06-02 Paul Eggert <eggert@cs.ucla.edu>
13270 * lib/autotest/general.m4 (AT_INIT): Don't create a regular
13271 expression of unbounded size when processing the --list
13272 option. This runs afoul of a limit of 399 bytes per regular
13273 expression on AIX. Problem reported by Ralf Wildenhues.
13275 2005-06-01 Paul Eggert <eggert@cs.ucla.edu>

13278 * doc/autoconf.texi (Particular Headers): Reword example
13279 for multiline stdbool replacement.
13280 (Setting Output Variables): Reword text a bit. Don't
13281 give all the details about |#_!!_#|.
13282 Reword description of line replacement.
13284 2005-05-31 Dan Manthey <dan_manthey@partech.com>
13286 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Output variables may
13287 now contain newlines, and substituted files must be referenced on
13288 a line alone; the sed scripts to substitute them are now very
13290 (_AC_SED_CMD_LIMIT): Added; single place to store limit on how many
13291 commands can be put in a sed script portably.
13292 * doc/autoconf.texi (Setting Output Variables): Document above
13293 changes. (Particular Header Checks) <AC_HEADER_STDBOOL>: Give exaple
13294 use of multiline substitution.

13300 From Ralf Menzel (trivial change).
13302 2005-05-25 Paul Eggert <eggert@cs.ucla.edu>
13304 * tests/local.at: Don't attempt to check for negated character
13305 classes in shell scripts. The test was too brittle.
13307 2005-05-25 Stepan Kasal <kasal@ucw.cz>
13309 * bin/autoconf.as: Don't use "shift 2"; it's not portable enough.
13310 * doc/autoconf.texi (Limitations of Builtins): Document this
13313 2005-05-24 Stepan Kasal <kasal@ucw.cz>
13315 * lib/m4sugar/m4sh.m4 (_AS_ECHO_LOG): New macro to factor out
13316 common code; used in many places in the tree.

13320 * lib/m4sugar/m4sugar.m4 (m4_ifset): Use m4_ifval.
13322 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Merge the two error
13323 messages when ac_unique_file is not found.
13324 (AC_CONFIG_MACRO_DIR): Simplify the `if' at the end.
13325 (AC_MSG_CHECKING, AC_MSG_RESULT): Put braces around the two echo
13326 commands, for consistency with AC_MSG_ERROR and such.
13328 * bin/autoconf.as: Make more use of "shift 2" in option processing.
13330 * bin/Makefile.am: Merge the two rules for creating scripts.

13338 2005-05-20 Stepan Kasal <kasal@ucw.cz>
13340 * NEWS: @top_builddir@ is now a dirname, ac_top_builddir will follow.
13341 * lib/autoconf/status.m4 (_AC_SRCDIRS): Rename ...
13342 (ac_top_builddir): ... this ...
13343 (ac_top_build_prefix): ... to this; the old name is also kept, for
13344 backward compatibility.
13345 (ac_top_builddir_sub): New variable, without the trailing slash,
13347 (_AC_OUTPUT_FILES): s/@top_builddir@/$ac_top_builddir_sub/
13348 * doc/autoconf.texi (Configuration Actions): Rename

13361 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Don't m4_quote the second
13362 argument to m4_foreach. I guess it was necessary in the past,
13363 but I think it's a no-op now.
13365 2005-05-17 Stepan Kasal <kasal@ucw.cz>
13367 * lib/autoconf/general.m4 (_AC_INIT_HELP): Merge two consecutive
13368 ``cat <<_ACEOF'' commands to one.
13369 (_AC_CANONICAL_SPLIT): Use expr, not ``echo|sed.''
13370 * lib/autoconf/status.m4: On various places, use expr instead of
13372 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST):

13376 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Use awk to search for
13377 the wrong patterns between ``case'' and ``esac.'' The previous
13378 code had false positives.

13442 abbreviations of --version and --debug.
13444 2005-05-10 Paul Eggert <eggert@cs.ucla.edu>
13446 * doc/autoconf.texi (Autoconf Language): Be more precise about
13447 quoting rules. Problems noted by Stepan Kasal.
13448 Also, throughout this document, be more careful about white space.
13449 "blank", "white space", and "space" all have different meanings
13450 and we should be careful to say what we mean.
13452 2005-05-05 Paul Eggert <eggert@cs.ucla.edu>

13469 * lib/autoconf/general.m4 (_AC_LIBOBJS_NORMALIZE): Prepend each
13470 object named in LIBOBJS and LTLIBOBJS with the ${LIBOBJDIR}, as
13471 set by latest automake.
13473 2005-05-01 Paul Eggert <eggert@cs.ucla.edu>
13475 * doc/autoconf.texi (Limitations of Usual Tools): "expr '' \| ''"
13476 outputs 0 on GNU/Linux these days.
13478 2005-04-29 Paul Eggert <eggert@cs.ucla.edu>
13480 * doc/autoconf.texi (Autoconf Language): Add more description
13481 about quoting heuristics.
13482 (Limitations of Builtins): Describe "set -" problems.
13484 2005-04-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
13486 * lib/autotest/general.m4 (AT_KEYWORDS): Separate by space,
13489 * doc/autoconf.texi (External Software): Replace AC_DEFINE_UNQUOTED
13490 by AC_DEFINE; it was a mistake.
13491 From bug reported against libtool by Dalibor Topic <robilad@kaffe.org>.
13493 2005-04-25 Stepan Kasal <kasal@ucw.cz>
13495 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): A tiny optimization.
13497 2005-04-22 Stepan Kasal <kasal@ucw.cz>
13499 * doc/autoconf.texi (External Software): Quadrigraphs are not
13500 processed correctly in AS_HELP_STRING; avoid this in the examples.
13501 * lib/m4sugar/m4sh.m4 (AS_HELP_STRING): Add a FIXME about quadrigraphs.
13502 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Likewise; and rephrase the
13503 comment and reduce m4_default([foo], []) to [foo].
13504 (m4_strip): Update the explanation.
13506 2005-04-19 Paul Eggert <eggert@cs.ucla.edu>
13508 * lib/autoconf/general.m4 (_AC_INIT_PREPARE, _AC_RUN_IFELSE):
13509 Remove core.conftest.* too; it's generated by Tru64 5.1.
13510 Problem reported by Jennis Pruett.
13511 * lib/autoconf/functions.m4
13512 (AC_FUNC_SETVBUF_REVERSED, AC_FUNC_UTIME_NULL):
13513 Don't bother to remove core files; AC_RUN_IFELSE should do that
13516 2005-04-19 Stepan Kasal <kasal@ucw.cz>
13518 * lib/m4sugar/m4sugar.m4 (m4_bpatsubsts): Add the b- to comment, too.

13530 2005-04-14 Gregorio Guidi <greg_g@gentoo.org>
13532 * doc/autoconf.texi (External Software, Package Options): Add
13533 examples showing how to implement --with-* and --enable-* options.
13535 2005-04-13 Paul Eggert <eggert@cs.ucla.edu>
13537 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Look for configure.ac
13538 as well as configure.in. Problem reported by Gregorio Guidi.
13540 2005-04-10 Paul Eggert <eggert@cs.ucla.edu>
13542 * doc/autoconf.texi (Particular Functions): Use gnulib's current

13556 fails if %s isn't supported. Problem reported by Ralf Wildenhues.
13558 2005-03-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
13560 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS):
13561 Merge `-z option' as well for the benefit of Solaris link flags. Pass
13562 whole-archive (-zallextract, -zdefaultextract) options in the hope of
13563 unique libraries, for the Sun Fortran 95 8.0 compiler. Bug reported
13564 against Libtool by Yury Puhalsky <pooh@cryptopro.ru>.
13566 2005-03-22 Paul Eggert <eggert@cs.ucla.edu>
13568 * NEWS: The configure command now warns you if you attempt to use
13569 a directory whose name contains a special character like space,
13571 * doc/autoconf.texi (Installation Directory Variables): Allow
13572 "," in file names. Do not use \@; it's not a portable regexp.
13573 * bin/Makefile.am (edit): Likewise.
13574 * lib/Makefile.am (edit): Likewise.
13575 * tests/Makefile.am (edit): Likewise.
13576 * tests/semantics.at: Likewise.

13579 * lib/autoconf/status.m4 (_AC_SRCDIRS): Likewise.
13580 * doc/autoconf.texi (File System Conventions): Warn about
13581 unportable file names.
13582 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): New macro.
13584 (_AC_INIT_SRCDIR): Use ac_pwd rather than invoking pwd.
13585 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Propagate
13586 ac_pwd, and quote srcdir.
13587 * lib/autotest/general.m4 (AT_INIT): Quote file name args.
13589 * doc/autoconf.texi: Fix some systematic formatting problems.
13590 ".)" needs a following @: if not at the end of a sentence, and
13591 similarly for "!)". "etc." should be preceded by a comma.
13592 "n-th" -> "@var{n}th". pdksh is still buggy, so update its date.
13594 2005-03-22 Bruno Haible <bruno@clisp.org>
13596 * doc/autoconf.texi (Input): Mention that AC_CONFIG_AUX_DIR's
13597 argument is often called 'build-aux'.
13599 2005-03-07 Stepan Kasal <kasal@ucw.cz>
13601 * doc/autoconf.texi (Quotation Rule Of Thumb): Mention that the
13602 macro AC_TRY_LINK is obsolete.
13603 (Installation Directory Variables): Change `AC_OUTPUT_FILES' to
13606 2005-02-24 Stepan Kasal <kasal@ucw.cz>
13608 * lib/autoconf/c.m4 (AC_PROG_CC): Be more careful to skip
13609 `/usr/ucb/cc'; use `cl.exe' to distinguish the MS compiler
13610 from a Common Lisp's `cl'.
13611 (AC_PROG_CXX): Behave according to the documentation: don't
13612 search for $ac_tool_prefix$CCC and $CCC, just set CXX=$CCC;
13613 make the variable CCC precious; use `cl.exe', not `cl'.
13615 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
13616 Alexandre Duret-Lutz <adl@gnu.org>
13618 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin from
13619 /dev/null, as "configure" shouldn't read stdin, and this insulates
13620 us from problems (e.g., when testing for "cl"). Also, do this
13621 redirection before invoking "hostname" or "uname", and keep the
13622 original input stream available via...
13623 (AS_ORIGINAL_STDIN_FD): ... this new macro.
13624 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't
13625 bother with "</dev/null" since it's now done at the top of
13627 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Likewise.
13628 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.

13634 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
13636 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N_PREPARE): Don't set ECHO_C to
13637 newline if neither \c nor -n work, as that would output two
13638 newlines. Prefer -n to \c. Reported by Stepan Kasal.
13640 2005-02-12 Stepan Kasal <kasal@ucw.cz>
13642 * lib/m4sugar/m4sh.m4 (AS_IF): Define by m4_defun, not m4_define.
13643 This causes that any required macros inside will get before the if.
13644 * doc/autoconf.texi (autom4te.cache): A typo.
13646 2005-02-12 Paul Eggert <eggert@cs.ucla.edu>
13648 Undo previous change, except keep the change to
13649 lib/autoconf/programs.m4 that replaced grep with shell
13650 pattern-matching. This is because net-snmp configure reads stdin.
13651 Reported by Noah Misch.
13653 2005-02-11 Paul Eggert <eggert@cs.ucla.edu>
13655 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin
13656 from /dev/null, as "configure" shouldn't read stdin, and this
13657 insulates us from problems (e.g., when testing for "cl").
13658 Suggested by Alexandre Duret-Lutz. Also, do this redirection
13659 before invoking "hostname" or "uname".
13660 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
13661 _AC_LINK_IFELSE): Undo previous change, as it's no longer needed.
13662 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Don't bother with
13663 "</dev/null" since it's now done at the top of 'configure'.
13664 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
13665 * lib/autoconf/programs.m4 (_AC_PATH_PROG_FLAVOR_GNU): Likewise.
13666 Also, replace grep with shell pattern-matching, to save a process.
13668 2005-02-10 Paul Eggert <eggert@cs.ucla.edu>
13670 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
13671 _AC_LINK_IFELSE): Redirect stdin to /dev/null, in an attempt to
13672 avoid thinking that Allegro Common Lisp's "cl" command is a C++
13675 2005-02-09 Paul Eggert <eggert@cs.ucla.edu>
13677 * doc/autoconf.texi (Limitations of Usual Tools): Document that
13678 grep -q isn't portable. Improve grep -s explanation.
13679 Problem reported by Dan Manthey.
13681 2005-02-08 Paul Eggert <eggert@cs.ucla.edu>
13683 * doc/autoconf.texi (Special Shell Variables): Clarify
13684 PATH_SEPARATOR wording; fix typo in IFS. Reported by Gary V. Vaughan.
13686 2005-02-07 Paul Eggert <eggert@cs.ucla.edu>
13688 * doc/autoconf.texi: Use @acronym for DJGPP.
13689 Fix some @code's that should have been @env's, and vice versa.
13690 Sort environment variable names.
13691 Mention that shells no longer inherit IFS.
13692 Don't recommend PATH_SEPARATOR=';' so strongly.
13693 Mention that $RANDOM might expand to the empty string.
13694 "symlink" and "soft link" -> "symbolic link".
13695 Improve mktemp description (reported by Bruno Haible).
13697 2005-02-05 Paul Eggert <eggert@cs.ucla.edu>
13699 * tests/foreign.at (Libtool): Don't overquote AT_SETUP arg.
13700 * tests/m4sh.at (AS_DIRNAME, AS_BASENAME, AS_MKDIR_P, AS_HELP_STRING):
13702 * tests/semantics.at (AC_C_BIGENDIAN, AC_PATH_PROG & AC_PATH_PROGS):
13705 2005-02-04 Paul Eggert <eggert@cs.ucla.edu>
13707 * NEWS: Mention AT_COPYRIGHT.
13709 * tests/local.at (AT_CMP): Use diff directly on input files rather
13712 * lib/autoconf/programs.m4 (AC_PROG_SED): Don't look in
13713 /usr/xpg4/bin since that sed dumps core (at least on Solaris 8).
13715 2005-02-04 Noah Misch <noah@cs.caltech.edu>
13716 and Paul Eggert <eggert@cs.ucla.edu>
13718 * tests/autotest.at (Empty test suite): New test.
13719 * tests/torture.at (Substitute and define special characters)
13720 (Substitute a 2000-byte string, Define to a 2000-byte string)
13721 (Substitute a newline, Define a newline): New tests.
13723 2005-02-04 Noah Misch <noah@cs.caltech.edu>
13725 * lib/m4sugar/m4sugar.m4 (m4_re_string, m4_re_word): Revert 2002-03-04.
13726 * tests/local.at (AT_CHECK_M4SUGAR): Add `m4sugar' to keywords.
13727 (AT_CHECK_ENV): Ignore LTLIBOBJS, FC variables, EGREP, FGREP, and SED.

13731 excess test name quoting.
13732 * tests/semantics.at (AC_CHECK_HEADERS_OLD, AC_CHECK_HEADERS_NEW): Pass
13733 CPPFLAGS to `configure' instead of setting it in `configure'.
13735 * lib/m4sugar/m4sh.m4 (AS_UNAME): Try only /usr/bin/hostinfo, not
13736 any `hostinfo' in $PATH, since hostinfo.exe is a popular file name
13739 * lib/autoconf/fortran.m4 (AC_LANG(Fortran), AC_FC_SRCEXT):
13740 s/FC_SRCEXT/ac_fc_srcext/; s/FCFLAGS_SRCEXT/ac_fcflags_srcext/.
13742 * tests/local.at (AT_CMP): New macro.
13743 (AT_DATA_AUTOCONF): Do not call AC_PROG_GREP.
13744 (AC_SAVE_STATE): Move environment grep...
13745 (AT_CHECK_ENV): to here. Filter out `'$''. Use AT_CMP.
13746 (AT_CONFIG_CMP): New macro.
13747 (AT_CHECK_MACRO): Run `configure' twice with cache and compare results.
13748 * tests/c.at (Extensions): Do not exit early.

13770 * lib/m4sugar/m4sugar.m4 (m4_re_escape): Escape ?, ^, \, $ too;
13771 this fixes a bug tickled by the AT_CAPTURE_FILE change noted below.
13773 Try not to generated lines of unlimited length, as POSIX places a
13774 2047-byte limit on line length of portable text files.
13775 * lib/autoconf/general.m4 (AC_SUBST, AC_SUBST_FILE):
13776 Use newline as a separator, not space.

13784 as_func_*. Add test to check whether positional parameters
13785 are restored after function return.
13787 2005-02-02 Paul Eggert <eggert@cs.ucla.edu>
13789 * doc/autoconf.texi (Special Shell Variables): Mention _,
13790 BIN_SH, DUALCASE. Say that variables other than "status" are safe
13791 if they contain a lower-case letter. The DUALCASE problem was
13792 reported by Ralf Wildenhues.
13794 * bin/autoconf.as: Don't exit with status 0 after write failure
13795 with --help or --version.
13796 * lib/autoconf/general.m4 (_AC_INIT_HELP, _AC_INIT_VERSION): Likewise.

13801 * doc/autoconf.texi (Limitations of Usual Tools):
13802 Unicos 9 sed limitations.
13803 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Try cf77 before fort77
13804 to get the option-enhanced interface on older Crays. Try ftn for
13805 Fortran 95 (newer Crays).
13807 2005-02-01 Paul Eggert <eggert@cs.ucla.edu>
13809 * man/Makefile.am (.x.1): Go back to the simple solution, but take
13810 care to echo the commands, so the user knows what's going on.
13811 Modified from a suggestion by Stepan Kasal.
13813 * doc/autoconf.texi (autoreconf Invocation): Mention autopoint,
13814 with a cross reference. Derived from a suggestion by Bruce Korb.

13823 * man/Makefile.am (.x.1): Make sure the required generated files
13824 are up to date. Problem and original solution proposed by Stepan Kasal.
13825 $(dist_man_MANS:.1=-bin-prereq), $(dist_man_MANS:.1=-tests-prereq),
13826 implicit-man-prerequisites): New rules, used by the above.

13834 Simplify the implementation of m4_require (a.k.a. AC_REQUIRE).
13835 Update the long comment explaining it.
13837 m4_require no longer writes an ``is required by'' line to the
13838 execution stack. It contains only one bit of non-redundant
13839 information: that the macro was required, not called. And even
13840 this bit is useless in most situations: have you ever met a macro
13841 which both calls and requires the same macro?
13843 * lib/m4sugar/m4sugar.m4 (_m4_defun_pro): Don't push a diversion...
13844 (_m4_defun_pro_outer): ... only via this macro, for the outermost

13847 (m4_expansion_stack_pop): Remove the misplaced comment.
13848 (m4_require): Don't put the ``is required by'' line to the
13849 execution stack; slightly improve the out-of-a-defun error message.
13850 (_m4_divert_grow): New macro, counter for the temporary diversions.
13851 (_m4_require_call): Use it.
13852 * tests/m4sugar.at (m4_require): Expect output without the
13853 ``is required by'' messages.
13855 2005-01-28 Paul Eggert <eggert@cs.ucla.edu>
13857 * doc/autoconf.texi (Limitations of Usual Tools): Recommend X
13858 rather than x for expr.

13889 2005-01-20 Paul Eggert <eggert@cs.ucla.edu>
13891 * doc/autoconf.texi (Shell Substitutions): Fix typo in case statement.

13948 (m4_divert, m4_divert_push, m4_divert_pop, m4_init): Use it.
13949 (m4_divert_push, m4_divert_pop, _m4_defun_epi): Don't expand the word
13950 stored in _m4_divert_diversion or _m4_divert_dump.
13951 (m4_divert_pop): When the parameter is given, compare the symbolic
13952 name with the last diversion pushed on the stack. Previously, the
13953 current diversion was compared with the numeric value of the
13954 diversion given as the parameter.
13955 (m4_require): If the macro hasn't been expanded yet, call ...

13989 * bin/autoreconf.in (autoreconf_current_directory): AM_INIT_AUTOMAKE

14042 * lib/autoconf/status.m4: Quote ``$tmp'' in many places.

14238 the spaces inside $ls_command. Problem reported by Loulou Pouchet in
14239 <http://lists.gnu.org/archive/html/autoconf/2004-12/msg00074.html>.
14240 Don't use "set - x"; plain "set x" is enough, and simplifies debugging.
14242 2004-12-07 Stepan Kasal <kasal@ucw.cz>
14244 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT): Fix typo in previous

14259 with exactly one parameter.
14261 2004-12-02 Paul Eggert <eggert@cs.ucla.edu>
14263 * lib/autoconf/functions.m4 (AC_FUNC_MEMCMP): Use
14264 "char c = '\200';" rather than "char c = 0x80;" as the
14265 latter doesn't conform to the strict C standard due to
14266 overflow on signed char hosts.
14268 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Prefer -qlanglvl=extc89
14269 to -qlanglvl=ansi. We don't want to disable extensions.
14271 2004-11-29 Paul Eggert <eggert@cs.ucla.edu>

14382 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): If xmkmf returns
14383 "/usr/include", clear ac_x_includes instead of leaving it as "no"
14384 (trivial change). Problem and patch reported by Andrew Church in:
14385 http://lists.gnu.org/archive/html/bug-autoconf/2004-04/msg00016.html

14417 Remove ansi2knr.c; nobody uses it.
14418 (ansi2knr.c-url_prefix): Remove.
14419 (cvs-update): Fix test for failure. I don't know why it ever
14422 * doc/autoconf.texi: Update URLs, some of which went stale.
14423 Use @uref rather than @href.
14425 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Have configure
14426 handle "--" as per POSIX. Suggested by Paul Pogonyshev.
14428 * config/config.guess, config/config.sub, config/elisp-comp,
14429 config/install-sh, config/mkinstalldirs, config/texinfo.tex,

14440 Use "file name" rather than "filename" or "path",
14441 to be consistent with the terminology of the GNU coding standards.
14443 2004-08-19 Paul Eggert <eggert@cs.ucla.edu>
14445 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C),
14446 AC_C_LONG_DOUBLE): Undo 2004-06-04 change, as it didn't work with
14447 HP-UX 11.23 cc/aCC or Tru64 4.0 cc. Problem reported by Noah Misch in
14448 <http://lists.gnu.org/archive/html/autoconf/2004-07/msg00004.html>.
14450 More fixes to support spaces in the name of the build directory.
14451 This isn't a complete fix but it's an improvement.
14453 * bin/autoconf.as (autom4te_options): New var.
14454 Use it instead of appending to AUTOM4TE, so that we can allow
14455 spaces in the build directory's absolute name.
14456 * bin/autoheader.in ($autoconf): Allow spaces in file names.
14457 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP, _AT_CHECK,
14458 AT_CHECK_NOESCAPE): Likewise.
14459 * tests/wrapper.as (testdir, AUTOM4TE_CFG, autom4te_perllibdir,

14470 * doc/autoconf.texi (Function Portability): Document isinf and
14471 and isnan. From a suggestion by Kevin Ryde.
14473 * lib/Autom4te/General.pm (END): Return correct exit status even
14474 if unlink succeeds and sets $?. Needed with Solaris 8's perl 5.00503.
14476 2004-08-09 Paul Eggert <eggert@cs.ucla.edu>
14478 * tests/torture.at (Deep Package): Use configure.in, not configure.ac,
14479 for compatibility with Automake 1.4. Reported by J C Fitzgerald in
14480 <http://lists.gnu.org/archive/html/bug-autoconf/2003-08/msg00051.html>.
14482 2004-08-04 Alexandre Duret-Lutz <adl@gnu.org>

14486 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Likewise for install-sh.
14487 * doc/autoconf.texi (Input): Document AC_REQUIRE_AUX_FILE.
14488 * lib/autom4te.in (Automake-preselections): Preselect
14489 AC_REQUIRE_AUX_FILE. Automake 1.10 will trace it.
14491 2004-08-02 Alexandre Duret-Lutz <adl@gnu.org>
14493 * lib/autom4te.in (Automake-preselections): Preselect
14494 AC_CANONICAL_BUILD and AC_CANONICAL_TARGET. Automake 1.9.1 will
14497 2004-07-29 Paul Eggert <eggert@cs.ucla.edu>

14502 Document problem with "`""`" in pdksh POSIX mode.
14504 2004-07-27 Paul Eggert <eggert@cs.ucla.edu>
14506 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): Use "set -o posix"
14507 with pdksh, too. Problem reported by Patrick Welche via
14509 * doc/autoconf.texi (Shellology): Note that set -o posix is
14510 useful for pkdsh, too.
14512 2004-06-24 Paul Eggert <eggert@cs.ucla.edu>
14514 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Require
14515 _AS_UNSET_PREPARE, so that we can use $as_unset directly.
14516 Don't fail if ENV or BASH_ENV is readonly.
14517 (AS_SHELL_SANITIZE): Don't fail if ENV, MAIL, MAILPATH, LC_ALL,
14518 etc. are read only. Problem reported by Ludovic Courtes.
14520 2004-06-23 Noah Misch <noah@cs.caltech.edu>
14522 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): If the shell is
14523 zsh, disable GLOB_SUBST to avoid backslash handling problems.
14526 2004-06-04 Paul Eggert <eggert@cs.ucla.edu>
14528 * doc/autoconf.texi (File System Conventions): Warn about
14529 names like "aux". Problem reported by Eric Blake.
14531 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY (C)): Use division
14532 by zero instead of array size, so that we can use any arithmetic
14533 constant expression (instead of requiring an integer constant
14534 expression). This allows us to test expressions like DBL_MAX <
14535 LDBL_MAX, which didn't conform to the C standard using the old
14537 (AC_C_LONG_DOUBLE): Put back in the tests for LDBL_MAX and LDBL_EPSILON,
14538 now that we can do floating-point tests at compile time.
14540 2004-06-02 Paul Eggert <eggert@cs.ucla.edu>
14542 * lib/autoconf/c.m4 (AC_C_LONG_DOUBLE): Don't check LDBL_MAX
14543 and LDBL_EPSILON, as the resulting expression isn't an
14544 integer constant expression and violates the C standard.
14545 Problem reported by Nelson H. F. Beebe. Also, check
14546 for "L" suffix, and check that long double doesn't have
14547 worse range or precision than double, that mixed-mode
14548 arithmetic doesn't generate a diagnostic, that double
14549 constants fit in long double.
14551 2004-06-03 Kevin Ryde <user42@zip.com.au>
14553 * doc/autoconf.texi (Function Portability): Add notes on free(NULL),
14554 malloc(0) and realloc(NULL,size).
14556 * doc/autoconf.texi (Shell Substitutions): Spelling error reported by
14559 2004-05-31 Paul Eggert <eggert@cs.ucla.edu>
14561 * lib/autoconf/headers.m4 (HAVE_STDBOOL_H): Detect _Bool bug
14562 in HP aC++/ANSI C B3910B A.05.55 [Dec 04 2003]. Problem reported
14565 2004-05-26 Paul Eggert <eggert@cs.ucla.edu>
14567 * doc/autoconf.texi (Limitations of Builtins): Mention that ! COMMAND
14568 can be rewritten using if-then-else. Suggested by Bruno Haible.
14570 2004-05-25 Paul Eggert <eggert@cs.ucla.edu>
14572 * doc/autoconf.texi (testsuite Scripts): Fix typo.
14573 Problem reported by Stepan Kasal.
14575 2004-05-24 Paul Eggert <eggert@cs.ucla.edu>
14577 * tests/Makefile.am (autoconfdir): Fix to match comment (trivial
14578 change). Patch reported by Ralf Wildenhues in
14579 <http://mail.gnu.org/archive/html/bug-autoconf/2004-05/msg00092.html>.
14581 * lib/autoconf/functions.m4 (AC_FUNC_MBRTOWC): Don't assume that a
14582 function F exists if the compiler and linker let you compile an
14583 expression like (F != 0). Recent versions of GCC optimize away
14584 the reference to F in that case, since every function address must
14585 be nonzero, so the link succeeds even if F does not exist.
14586 Problem reported by Manu in
14587 <http://mail.gnu.org/archive/html/bug-gnu-utils/2004-05/msg00060.html>.
14589 * doc/autoconf.texi (Systemology): Standardize on the spelling of
14590 "Unix". Many uses changed.
14591 (Limitations of Builtins): Explain better why the ! command isn't
14594 2004-05-22 Alexandre Duret-Lutz <adl@gnu.org>
14596 * lib/autom4te.in (Automake-preselections): Preselect
14597 LT_SUPPORTED_TAG in lieu of AC_LIBTOOL_TAGS.
14599 2004-05-19 Kevin Ryde <user42@zip.com.au>
14601 * doc/autoconf.texi (Function Portability): Add strerror_r, cross
14602 referencing AC_FUNC_STRERROR_R.
14604 * doc/autoconf.texi (Particular Functions): In AC_FUNC_CLOSEDIR_VOID,
14605 note pessimistic assumption when cross compiling.
14607 2004-05-16 Paul Eggert <eggert@cs.ucla.edu>
14609 * doc/autoconf.texi (Limitations of Make): Note that BSD make
14610 (until 2004) invoked subcommands with sh -e, contra POSIX.
14611 Reported by Kevin Ryde.
14613 2004-05-10 Eric Sunshine <sunshine@sunshineco.com>
14615 * programs.m4 (_AC_PROG_GREP): Fixed bug where PATH argument handed to
14616 _AC_PATH_PROG_FEATURE_CHECK contained leading whitespace (i.e.
14617 " $PATH:/usr/xpg4/bin"). This resulted in bogus tests, such as
14618 `test -f " /usr/bin/grep"', which _always_ failed.
14619 (AC_PROG_SED): Ditto bogus PATH fix.
14620 * autoconf.texi (AC_PROG_GREP): Properly document that this macro
14621 requires that grep correctly supports _multiple_ `-e' options, rather
14622 than stating only that grep should accept `-e'.
14624 2004-05-03 Paul Eggert <eggert@cs.ucla.edu>
14626 Port to C99, which requires that 'exit' be declared.
14628 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Use AC_INCLUDES_DEFAULT
14629 to ensure that stdlib.h is included.
14630 * lib/autoconf/functions.m4 (_AC_LIBOBJ_ALLOCA, AC_FUNC_SETPGRP,
14631 AC_FUNC_STRTOD, AC_FUNC_SETVBUF_REVERSED, AC_FUNC_FORK, _AC_FUNC_FORK,
14632 _AC_FUNC_VFORK, AC_FUNC_WAIT3): Likewise.
14633 * lib/autoconf/specific.m4 (AC_SYS_RESTARTABLE_SYSCALLS): Likewise.
14634 * lib/autoconf/types.m4 (AC_TYPE_GETGROUPS): Likewise.
14635 * lib/autoconf/headers.m4 (AC_HEADER_STDC): Include <stdlib.h>
14636 when using 'exit' in a test; C99 requires that 'exit' be declared.
14638 2004-05-02 Paul Eggert <eggert@cs.ucla.edu>
14640 * doc/autoconf.texi (Particular Programs): AC_PROG_GREP
14641 now prefers 'grep' implementations that accept -e.
14642 (Limitations of Usual Tools): Describe problems of traditional
14643 egrep and fgrep with long input lines, and of traditional grep
14645 * lib/autoconf/programs.m4 (AC_PROG_GREP): Check for -e, too.
14646 (_AC_PROG_GREP): Assume 3rd arg is properly quoted for the shell.
14647 All callers changed. Append /usr/xpg4/bin to the PATH, for
14649 (_AC_FEATURE_CHECK_LENGTH): Discard stderr, so we don't bother
14650 the user with complaints about multiple -e options.
14651 * tests/local.at (AC_STATE_SAVE): Use $GREP, not grep.
14652 Define it with AC_PROG_GREP.
14653 * configure.ac (AC_PROG_GREP): Add.
14654 * lib/freeze.mk (GREP): New macro.
14656 2004-05-02 Eric Sunshine <sunshine@sunshineco.com>
14658 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Consult $SHELL as
14659 a possible candidate only after all others fail, rather than
14660 consulting it first. This improves backward compatibility by
14661 better reflecting the way shell selection occurred in previous
14662 versions of Autoconf, and should help to avoid triggering latent
14663 problems in other packages, such as the one in Automake where zsh
14664 is not handled robustly:
14665 http://mail.gnu.org/archive/html/automake/2004-04/msg00095.html
14666 Although it is not Autoconf's responsibility to work around
14667 problems in Automake, it nevertheless makes sense to avoid
14668 introducing unnecessary incompatibilites.
14670 2004-04-22 Albert Chin-A-Young <china@thewrittenword.com>,
14671 Gary V. Vaughan <gary@gnu.org>
14673 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Don't guess
14674 how deeply nested we are when a suitable tool is found, set the
14675 ac_path_TOOL_found flag.
14676 (_AC_PATH_PROG_FEATURE_CHECK): Encapsulate knowledge of how deeply
14677 nested we are in this macro. Break out of all 3 nested loops if
14678 ac_path_TOOL_found is set.
14680 2004-04-21 Gary V. Vaughan <gary@gnu.org>
14682 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Break out
14683 of the _AS_PATH_WALK loop too if GNU flavor is found.
14685 2004-04-21 Alexandre Duret-Lutz <adl@gnu.org>
14687 * doc/autoconf.texi (Limitations of Make): Update documentation
14688 for `$<'. New entry `Long lines', based on a report from Simon
14689 Josefsson. Augment the documentation for SHELL = @SHELL@ with a
14690 paragraph about DJGPP, based on a mail from Richard Dawe.
14692 2004-04-20 Paul Eggert <eggert@twinsun.com>
14694 * tests/c.at (C keywords): Don't assume that GCC supports
14695 "restrict" and "inline", as sufficiently-old GCC versions do not
14696 (also, GCC configured to be in pedantic C89 mode does not).
14697 Problem reported by Sumit Pandya in:
14698 http://mail.gnu.org/archive/html/autoconf/2004-04/msg00092.html
14700 * lib/autoconf/c.m4 (_AC_PROG_CC_G, _AC_PROG_CXX_G): Don't
14701 consider -g to work if it generates warnings when plain compiles
14702 don't. Problem reported by Braden McDaniel in:
14703 http://mail.gnu.org/archive/html/autoconf-patches/2003-07/msg00014.html
14705 * doc/autoconf.texi (Slashes): New section, to document a problem
14706 reported by Jim Meyering in:
14707 http://mail.gnu.org/archive/html/bug-coreutils/2004-02/msg00060.html
14709 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Remove potential
14710 linker output files before linking, to work around IRIX 6 linker bug.
14711 Problem reported by Rainer Orth in:
14712 http://mail.gnu.org/archive/html/autoconf-patches/2004-02/msg00007.html
14714 2004-04-20 Gary V. Vaughan <gary@gnu.org>
14716 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Make the
14717 best tool so far counter rely on the tool path variable name to
14718 avoid checks for one tool being affected by the results of running
14719 the length check on a previous tool.
14721 * lib/autoconf/programs.m4 (_AC_PROG_GREP): Take an additional
14722 match expression argument, as different greps have different

14827 * bin/Makefile.am (edit): Don't use $< in a context where
14828 POSIX doesn't require support for it. Use $@.in instead.
14829 Problem reported by Anthony N. Frasso in
14830 <http://mail.gnu.org/archive/html/autoconf/2004-03/msg00008.html>.

14846 Fix a dependencies problem, stemming from a Autoconf 2.59 build
14847 problem on QNX reported by Stephen Rasku in

14850 * bin/Makefile.am ($(srcdir)/autoconf.in): Depend on

14854 one per related section. Add $(srcdir)/wrapper.in.

14859 AC_SUBST provides no portable way to escape literal newlines.
14861 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS): Ignore all
14862 flags of the form -lcrt*.o, not just -lcrt[01].o and -lcrtbegin.o.
14863 Darwin uses -lcrt2.o and there's little point to cataloging all
14864 the system variants. Partial fix reported by Andreas Waechter in:

14889 Eric Sunshine <sunshine@sunshineco.com>
14890 Paul Eggert <eggert@twinsun.com>
14892 * lib/m4sugar/m4sh.m4 (M4SH-SANITIZE): New diversion.
14893 (AS_INIT): Output shell initialization there. Removed optional
14894 parameter. Expand _AS_SHELL_FN_SPY.

14907 trigger the bash bug anymore.
14908 * lib/autotest/general.m4: Document M4SH-SANITIZE, do not
14909 use AS_INIT_WITH_SHELL_FN.
14910 * bin/autoconf.in, tests/wrapper.in: Regenerated.
14912 2004-01-30 Paolo Bonzini <bonzini@gnu.org>

14919 macros with AU_DEFINE.

14942 the 2003-05-22 change, which removed the older years from the list.
14943 * lib/autoconf/status.m4 (AC_OUTPUT): Update copyright date to 2004.

14956 _AC_PROG_GREP, and AC_PROG_SED.
14957 (_AC_FEATURE_CHECK_LENGTH): New helper macro for finding the
14958 longest input length accepted by a command.

14987 2004-01-26 Paul Eggert <eggert@twinsun.com>
14989 * doc/autoconf.texi (Default Includes): Include <stdint.h> even if
14990 HAVE_INTTYPES_H is defined. This is needed on Tru64 5.1b with
14991 Compac C V6.5-207 (dtk), which defines uintmax_t in <stdint.h> but
14992 not <inttypes.h>. Problem reported by Tim Mooney in
14993 <http://mail.gnu.org/archive/html/bug-coreutils/2004-01/msg00147.html>.
14994 * lib/autoconf/headers.m4 (_AC_INCLUDES_DEFAULT_REQUIREMENTS):
14997 * lib/autoconf/programs.m4 (AC_PROG_SED): Use diff, not sed;
14998 otherwise "make check" fails because it forbids cmp (I guess
14999 because cmp treats files as binary on DOS-like systems).
15001 * tests/mktests.sh: Update copyright date to 2004, since some tests
15002 have changed in 2004.
15004 2004-01-23 Gary V. Vaughan <gary@gnu.org>
15006 * lib/autoconf/programs.m4 (AC_PROG_SED): New macro to test for a
15007 non-truncating sed or gsed program in PATH.
15008 * tests/acprograms.at: Add it.
15009 * doc/autoconf.texi (Particular Programs): Document it.
15012 2004-01-15 Paul Eggert <eggert@twinsun.com>
15014 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Try -std, not -std1, since
15015 -std1 disables some useful extensions on Tru64. Problem reported
15016 by N. Lichtmaier in
15017 <http://mail.gnu.org/archive/html/autoconf/2004-01/msg00100.html>.
15019 2004-01-14 Paul Eggert <eggert@twinsun.com>
15021 * doc/autoconf.texi (Programming in M4sh): Document that
15022 AS_MKDIR_P succeeds if the destination is a symbolic link
15023 to an existing directory.
15024 (Limitations of Usual Tools): Note that mkdir -p might not
15025 succeed on symlinks to directories.
15027 2004-01-13 Paul Hilfinger <hilfinger@CS.Berkeley.EDU>
15029 * lib/autoconf/autoupdate.m4 (AU_DEFUN): Grammar fix in comment.
15030 * bin/autoheader.in: Grammar fix in message.
15031 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P):
15032 Test for dir before calling mkdir -p. (trivial changes)

15039 2004-01-10 Jim Meyering <jim@meyering.net>

15043 2004-01-09 Paul Eggert <eggert@twinsun.com>
15045 * lib/autoconf/general.m4: Fix bug: AC_CHECK_SIZEOF evokes a warning
15046 with `autoconf -Wall,error'. Bug reported by Eric Blake in:
15047 http://mail.gnu.org/archive/html/autoconf-patches/2004-01/msg00000.html
15048 (_AC_COMPUTE_INT_COMPILE): Invoke _AC_COMPILE_IFELSE, not
15049 AC_COMPILE_IFELSE, since we now assume our caller invokes
15050 AC_LANG_COMPILER_REQUIRE, for symmetry with _AC_COMPUTE_INT_RUN.
15051 (_AC_COMPUTE_INT_RUN): Likewise, for _AC_RUN_IFELSE instead
15052 of AC_RUN_IFELSE; this avoids the warning mentioned above.
15053 (_AC_COMPUTE_INT): Invoke AC_LANG_COMPILER_REQUIRE.
15055 2004-01-07 Paul Eggert <eggert@twinsun.com>
15057 * lib/autoconf/general.m4 (_AC_LIBOBJS_NORMALIZE): Avoid \$ inside
15058 `"'...'"`, as it's confusing (and I suspect it may not work on
15059 some platforms). The code was incorrect anyway, as it assumed
15060 that \$ evaluated to itself in that context. Reported by
15061 Alexandre Duret-Lutz.
15063 2004-01-07 Alexandre Duret-Lutz <adl@gnu.org>
15065 * lib/autom4te.in (Automake-preselections): Preselect AC_LIBTOOL_TAGS
15066 and _LT_AC_TAGCONFIG.

15089 by doing lineno substitution only on lines containing "$LINENO".
15091 2004-01-04 Paul Eggert <eggert@twinsun.com>
15093 * lib/autoconf/general.m4 (AC_ARG_PROGRAM):
15094 Use "rm -f" to remove conftest.sed, not plain "rm".
15095 Bug reported by David Relson in
15096 <http://mail.gnu.org/archive/html/autoconf/2004-01/msg00011.html>.
15098 * Makefile.am (autom4te-update):
15099 Replace "rm -rf" and "rm -fr" with "rm -f -r", as POSIX requires.

15113 2004-01-03 Paul Eggert <eggert@twinsun.com>
15115 * doc/autoconf.texi (Limitations of Usual Tools): Mention that cc
15116 -c -o might not work. From a suggestion by Kevin Ryde.
15117 (C Compiler, Generating Sources, Limitations
15118 of Usual Tools, Limitations of Make, Making testsuite Scripts):
15119 Don't put '-o' after non-options, as POSIX doesn't allow this.
15120 Mention that cc's name might be gcc or c89 or whatever.
15122 2004-01-04 Kevin Ryde <user42@zip.com.au>
15124 * doc/autoconf.texi: Add various further index entries.
15126 2003-12-29 Paul Eggert <eggert@twinsun.com>
15128 * bin/autoreconf.in (autoreconf_current_directory):
15129 Fix typo: mkdir without umask arg.
15131 2003-12-27 Alexandre Duret-Lutz <adl@gnu.org>
15133 * doc/autoconf.texi (Limitations of Make) <Automatic rule rewriting>:
15134 Documents OSF1/Tru64 make behavior. Replace `VPATH = ../src' by
15135 `VPATH = ../pkg/src' in examples to make the OSF1/Tru64 make
15136 explanation clearer.
15138 2003-12-24 Andreas Schwab <schwab@suse.de>
15140 * doc/autoconf.texi (Default Includes): Fix misspelling of

15146 * configure: Regenerate.
15147 * tests/atlocal.in: Store the result here.
15148 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Extracted from

15150 of explicitly testing.

15421 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Omit quoted

15447 cache variable instead of $G77 to decide whether to include -O2,

15458 arguments so that it can be used with syntax identical to

15460 remove/deprecate the DIALECT optional argument in the future if it
15461 proves troublesome.
15462 (AC_FC_FREEFORM): Exit 77 upon failure to fix test suite for

15534 * lib/autoconf/status.m4 (_AC_OUTPUT_COMMANDS): Make sure the
15535 directory for AC_CONFIG_COMMANDS' first argument exists.
15536 This makes valid the invocation of _AC_SRCPATH that follows.
15537 Reported by Eric Sunshine.

15561 The test suite are sometimes assigning timings incorrectly.
15562 Reported by Henk Krus.
15563 Diagnosed by Nicolas Joly.
15565 * lib/autotest/general.m4 (AT_CLEANUP): Rename AT_help as
15567 Instead of making AT_help a sequence of assignments to grow

15569 $at_help_all, and make a single assignment in...
15571 (at_times_skip): Flip the meaning and rename as...
15572 (at_times_p): this.

15585 executables, not bin/ executables! Otherwise all the magic needed
15586 to find non installed files is turned off. This caused a failure
15587 of test 40 and 41 that ran aclocal 1.8 which in turn ran autom4te
15588 as found in its environment (sent by tests/autoreconf): pointing
15589 to bin/autom4te that could not find its files.
15590 * tests/mktests.sh: Force the replacement of generated files, for
15591 the sake of "mv" program that are interactive when overwriting a

15690 correspond to all the old F77 macros, with output variables FC,
15691 FCFLAGS, and FCLIBS. AC_PROG_FC defaults to picking the newest

15820 2003-08-21 Akim Demaille <akim@epita.fr>
15822 First stab at preserving warnings between calls to autom4te,
15823 including when the cache is used.
15825 There are still several issues: (i) there are too many runs of m4
15826 (one for include, one for warnings, and some more), (ii) warnings
15827 spreading on several lines are not handled gracefully, (iii) the
15828 code meant to have the call stack display for errors does not work
15829 (its handling should move from m4 to autom4te).
15831 * bin/autom4te.in Autom4te::Channels, Autom4te::ChannelDefs):
15833 (@preselect): Add m4_warn.
15834 ($exit_status): Remove, use $exit_code.
15835 ($help): Use Autom4te::ChannelDefs::usage.
15836 (&handle_m4): No longer define the m4_warnings.
15837 At each run, extract and report the warnings.
15838 Always cache the result, including if the exit status is on
15839 failure, since if nothing changes, we should result in the same
15840 failure, hence we can use the cache.
15841 * lib/m4sugar/m4sugar.m4 (m4_warning_ifelse, _m4_warning_ifelse)
15842 (_m4_warning_error_ifelse, __m4_warning_error_ifelse, _m4_warn):
15844 (m4_warn): Redefine as a do-nothing: it is its invocation that
15845 matters, as warnings are now reported via traces.
15846 * lib/autoconf/general.m4 (AC_DIAGNOSE): Don't make it a copy of
15847 the contents of m4_warn: make it _call_ m4_warn, so that tracing
15848 the latter reveals calls to the former.
15852 * tests/m4sugar.at (m4@&t@_warn): Use existing warning categories.

15874 (&catfile): Remove.
15875 * bin/autoheader.in, bin/autoreconf.in, bin/autoupdate.in,

15881 Reported by Alexandre Duret-Lutz.

15885 * bin/autoupdate.in, bin/autoheader.in, bin/autoreconf.in,
15886 * bin/autom4te: Adjust.
15887 In particular, be Autoconf tools are really silent when properly
15888 working, bind the verbosity of the 'note' channel to $verbose.
15889 * lib/Autom4te/General.pm (&find_file, &mtime, &update_file)

16130 * Makefile.am, bin/Makefile.am, config/Makefile.am,
16131 * doc/Makefile.am, lib/autoconf/Makefile.am, tests/Makefile.am:
16132 White spaces cleanup.

16135 Paul Eggert <eggert@twinsun.com>
16137 * lib/autoconf/c.m4 (_AC_PROG_CXX_EXIT_DECLARATION):
16138 Remove `#include <stdlib.h>' from the list; we should never
16139 make confdefs.h include <stdlib.h> or <cstdlib>, because the
16140 resulting namespace pollution would cause other tests to fail.
16141 Configure scripts run with some older versions of g++ and HP's
16142 aCC would fail due to such an #include. Problems reported by
16143 Matthew Mueller in <http://bugs.debian.org/120704> and by
16145 <http://mail.gnu.org/archive/html/autoconf/2003-05/msg00063.html>.
16146 In the test, use the test declaration before including <stdlib.h>,
16147 as that's closer to how it'll be used.
16149 2003-05-23 Akim Demaille <akim@epita.fr>
16151 * doc/autoconf.texi (Header Portability): ucred.h.
16154 2003-05-22 Paolo Bonzini <bonzini@gnu.org>
16156 Overhaul Autotest's logging: generate separate log files
16157 in testsuite.dir/NNN/testsuite.log, and append them to
16158 testsuite.log instead of re-running the test verbosely.
16160 * lib/autotest/general.m4 (AT_INIT): Use a single redirected
16161 file descriptor, write 0 to at_status_file instead of setting
16162 at_status=0, initialize some new variables (at_status_file,
16163 at_group_log, at_suite_log, at_tee_pipe). Remove the cruft
16164 to rerun the tests, instead append the at_group_log to the
16165 at_suite_log when a test fails.
16166 (AT_SETUP): pipe the test case's output into at_tee_pipe,
16167 with the AS_MESSAGE_LOG_FD redirected to stdout.
16168 (AT_CLEANUP): save the output status in $at_status_file
16169 and restore it, redirect the AS_MESSAGE_LOG_FD back to
16170 its original place.
16171 (AT_CHECK): since tests are run with a redirected stdout,
16172 and used to be re-run in verbose mode, turn some $at_verbose
16173 into echo, and don't redirect the output of testing stdout
16176 * lib/autotest/autoconf.texi (testsuite Scripts): Update
16177 the name of the debugging directory and information about

16297 2003-05-06 Akim Demaille <akim@epita.fr>
16299 Don't try to be smart with aclocal 1.8+ because (i) aclocal no
16300 longer updates aclocal.m4 if useless, (ii) if a file m4_included
16301 by aclocal.m4 is changed it might require the importing of another
16302 m4 extension file, i.e., aclocal must be run.
16304 * bin/autoreconf.in (&run_aclocal, $aclocal_supports_force): New.
16305 (&parse_args): Use --force with aclocal if required and supported.

16319 2003-04-29 Derek Price <derek@ximbiot.com>
16321 * lib/autotest/general.m4 (AT_KEYWORDS): Don't use a comma as the
16322 seperator with m4_append_uniq(). It doesn't work.
16323 (AT_CLEANUP): Add `;' to end of at_help_all.
16324 (AT_INIT): Allow --keywords to be specified more than once. When
16325 grepping $at_help_all for keywords, use the field and keyword
16326 seperators to ensure a complete keyword match. Alter at_prev handling
16327 to support the new --keywords behavior.
16329 2003-04-27 Karl Berry <karl@freefriends.org>
16331 * doc/autoconf.texi: Make the dir entries in the autoconf manual
16332 align better with others. I also made some of the individual
16333 entries on one line, for brevity and to make it easier for me to
16334 sort my dir-example file in the Texinfo distribution :).

16405 * tests/torture.at (Configuring subdirectories): Require aclocal
16406 1.4, otherwise the test fails, as it does support configure.ac.

16554 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Define $1 to an
16555 innocuous variant befor including <limits.h> or <assert.h>. This

16557 (and earlier versions) have a <limits.h> that declares
16558 gettimeofday and many other functions.
16560 2002-12-03 Paul Eggert <eggert@twinsun.com>

16574 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C),
16575 _AC_PROG_PREPROC_WORKS_IFELSE): Use <limits.h> if __STDC__ is
16576 defined, to support freestanding compilers. This should fix the
16577 bug reported by Momchil Velkov in
16578 <http://mail.gnu.org/pipermail/autoconf/2002-November/014490.html>.
16580 * doc/autoconf.texi (Obsolete Macros): Fix typos (insert empty
16581 arg, AC_DEFINE -> AC_DEFINE_UNQUOTED) in documentation for

16616 * Makefile.maint: Sync with Bison, i.e.:
16617 (po-check): Scan .l and .y files instead of the
16618 .c and the .h files that they generate. This fixes the bug
16619 reported by Tim Van Holder in:
16620 <http://mail.gnu.org/pipermail/bison-patches/2002-November/001352.html>
16621 Look for N_ as well as for _. Try to avoid matching #define for
16625 2002-11-14 Akim Demaille <akim@epita.fr>

16630 2002-11-14 Akim Demaille <akim@epita.fr>

16633 From Paul Eggert and Albert Chin-A-Young.
16635 2002-11-14 Kevin Ryde <user42@zip.com.au>
16637 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Initialize f=$1 rather
16638 than assigning in main, to avoid HP cc +O3 optimizing it away.
16640 2002-11-12 Peter Eisentraut <peter_e@gmx.net>
16642 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Add -q
16643 option. Process --recheck after parsing all options. Pass -q
16644 option to configure on --recheck.
16645 (AC_OUTPUT): Pass -q from configure to config.status.
16646 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Strip -q from
16647 arguments to record.
16648 * doc/autoconf.texi (config.status Invocation): Document
16649 config.status -q option.
16651 2002-11-07 Alexandre Duret-Lutz <adl@gnu.org>
16653 * bin/autoscan.in (scan_file): Scan Makefile.am too. Ignore
16654 Makefile.in if Makefile.am exists.

16676 Reported by Ezra Peisach.
16678 2002-11-05 Akim Demaille <akim@epita.fr>
16680 * lib/autoconf/autoheader.m4 (_AH_TEMPLATE_OLD, _AH_VERBATIM_OLD):
16682 We _have_ to stop using the old compatibility scheme that tried to
16683 avoid useless backslashes because Libtool 1.4.3 contains a
16684 AC_DEFINE([error_t], [int],
16685 [Define to a type to use for \`error_t' if it is not
16686 otherwise available.])
16687 We _have_ to quote the single quote and backslashes with \. The
16688 old compatibility scheme saw that ` was backslashed, and therefore
16689 did not quote the single quote. Hence before this patch, Autoconf
16690 was not compatible with Libtool.

16714 * doc/autoconf.texi (autoreconf Invocation): Adjust.

16736 Make variable, not a shell variable.
16737 Suggested by Bruno Haible.

16741 * bin/autom4te.in (load_configuration): Reject #args out of any

16763 AC_FUNC_REALLOC check for compatibility with glibc, not POSIX.
16764 Problem reported by Bruno Haible.

17081 Reported by Alexandre Duret-Lutz.
17083 * bin/autom4te.in (&parse_args): Do not prepend `--reload-state'

17111 * tests/semantics.at (AC_C_BIGENDIAN): Likewise.
17113 2002-10-11 Akim Demaille <akim@epita.fr>
17115 No longer use CPP to check for the existing of headers: use CC to
17116 check for compilability.
17118 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL)
17119 (AC_CHECK_HEADER, _AC_CHECK_HEADER_OLD): Remove.
17120 (_AC_CHECK_HEADER_NEW): Rename as...
17121 (AC_CHECK_HEADER): this.
17123 * lib/autotest/general.m4 (AT_INIT): Include the failed test
17124 numbers in the Subject suggestion.
17126 2002-10-11 Akim Demaille <akim@epita.fr>
17128 * lib/autoconf/specific.m4 (AC_DECL_SYS_SIGLIST): Obsolete.
17129 Suggest using AC_CHECK_DECLS instead.
17131 2002-10-11 Akim Demaille <akim@epita.fr>
17133 * tests/torture.at (AC_ARG_VAR): Have configure report the value
17136 2002-10-11 Akim Demaille <akim@epita.fr>
17138 * lib/m4sugar/m4sh.m4 (_AS_PATH_SEPARATOR_PREPARE): Use $$ in the
17139 file name to enable parallel executions.
17140 From Sam Varshavchik.
17142 2002-10-08 Akim Demaille <akim@epita.fr>
17144 * bin/autoreconf.in (&autoreconf): Run autopoint before the first
17145 aclocal invocation, as Gettext macros might not be visible to
17147 Instead of blindly running autopoint, scan configure.ac (not the
17148 traces) for AM_GNU_GETTEXT_VERSION uses, as autopoint does.
17149 Reported by Paul D. Smith.
17151 2002-10-08 Paul Eggert <eggert@twinsun.com>
17153 Work around problems found when POSIXLY_CORRECT=1 is set.
17154 None of this seems to have anything to do with POSIX, really,
17155 but it's how Perl getopt works.
17156 * bin/autom4te.in (parse_args): Configure GetOpt with
17158 * doc/autoconf.texi (Invoking autom4te):
17159 --warning -> --warnings.
17160 * lib/autom4te.in: --warning -> --warnings.
17162 2002-09-28 Akim Demaille <akim@epita.fr>
17164 * doc/autoconf.texi (autom4te.cache): New section.
17166 2002-09-28 Akim Demaille <akim@epita.fr>
17168 * lib/autom4te.in (Autoscan-preselections, Autoreconf-preselections)
17169 (Automake-preselections): Update.

17172 2002-09-28 Akim Demaille <akim@epita.fr>

17175 * lib/autoconf/c.m4, lib/autoconf/functions.m4,
17176 * lib/autoconf/headers.m4, lib/autoconf/libs.m4,
17177 * lib/autoconf/specific.m4, lib/autoconf/types.m4: here.
17179 2002-09-28 Akim Demaille <akim@epita.fr>
17181 * tests/torture.at (Configuring subdirectories): Be robust to
17182 users who use config.site to require for a cache: in this case,
17183 the two last configure runs, using two different sets of
17184 arguments, trigger a legitimate error.
17186 2002-09-28 Akim Demaille <akim@epita.fr>
17188 * tests/m4sh.at (Functions Support, Functions and return Support):
17191 2002-09-28 Akim Demaille <akim@epita.fr>
17193 * bin/Makefile.am (ETAGS_SH, ETAGS_PERL): Update: ifnames and
17194 autoheader are Perl programs.
17195 (autoconf, autoheader, autoreconf, autoupdate, ifnames, autoscan)
17196 (autom4te): Specify that the sources are in the $srcdir.

17204 * lib/autoscan/autoscan.pre (AWK, BISON, INSTALL, LEX, LN, MAKE)
17205 (RANLIB, YACC, awk, bison, byacc, flex, gawk, install, lex, ln)
17206 (make, mawk, nawk, ranlib, yacc): Similarly, move to...
17207 * lib/autoconf/programs.m4: here.

17217 that were listed in the original autoscan.list.
17218 * lib/autoconf/headers.m4: Similarly with headers.
17219 * lib/freeze.mk (autoconf_m4f_dependencies): Add autoscan.m4.
17220 (.m4.m4f): Don't pass --prepend-include, since that's done by
17221 tests/autom4te itself.
17222 * lib/autoscan/Makefile.am: Include freeze.mk.
17223 (autoscan.list): New target --this file is no longer a source.
17224 (autoscan.pre): New file.
17226 2002-09-28 Akim Demaille <akim@epita.fr>
17228 * bin/autoscan.in (@kinds): Make them singular.
17230 (&init_tables): When --debug, report the list of rules to ease
17231 tracking changes in autoscan.list.
17232 * lib/autoscan/autoscan.list (function): Strip comments, sort.
17234 2002-09-28 Akim Demaille <akim@epita.fr>
17236 * lib/autoscan/functions, lib/autoscan/headers,
17237 * lib/autoscan/identifiers, lib/autoscan/makevars,
17238 * lib/autoscan/programs: Merge into...
17239 * lib/autoscan/autoscan.list: this.
17240 * bin/autoscan.in (&init_tables): Adjust.
17242 2002-09-28 Akim Demaille <akim@epita.fr>
17244 * lib/autoscan/functions, lib/autoscan/headers,
17245 * lib/autoscan/identifiers, lib/autoscan/makevars,
17246 * lib/autoscan/programs: Make the `kind' explicit, i.e., each
17247 `functions' line is now prefixed with `function:'.
17248 * bin/autoscan.in (&init_tables): Adjust.
17250 2002-09-28 Akim Demaille <akim@epita.fr>
17252 From now on, autoscan files must always map a macro name to a
17253 word: there is no `default' macro for autoscan.
17255 * bin/autoscan.in (&init_tables): Reject entries with no macro at
17257 * lib/autoscan/functions, lib/autoscan/headers: Make the macro
17260 2002-09-28 Akim Demaille <akim@epita.fr>
17262 * bin/autoscan.in (%c_keywords): Remove.
17263 (&used): Keep only track of the words we might be interested in.
17264 (&output_kind): It is no longer needed to look for non active
17267 2002-09-27 Akim Demaille <akim@epita.fr>
17269 * lib/autoconf/functions.m4 (AC_FUNC_MBRTOWC): New, stolen from

17271 * lib/autoscan/functions: Adjust.
17272 * doc/autoconf.texi (Particular Functions): Adjust.
17274 2002-09-27 Akim Demaille <akim@epita.fr>

17278 Thanks to Bill Moseley and Paul Eggert.
17279 * lib/m4sugar/m4sh.m4 (AS_TMPDIR): $2 is the directory into which
17280 the tmpdir must be created.
17281 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Have the tmp
17282 dir be in the build tree, instead of $TMPDIR.
17284 2002-09-27 Akim Demaille <akim@epita.fr>
17286 * bin/autoscan.in: Improve the comments.
17287 (&parse_args): Drop obsolete undocumented options.
17288 (&output_kind): Output warnings.
17289 * lib/autoscan/functions: (dcgettext): Now trigger AM_GNU_GETTEXT.

17292 2002-09-26 Akim Demaille <akim@epita.fr>
17294 * bin/autoreconf.in: Clarify that -s is meaningless without -i.
17295 Reported by Ralf Corsepius.
17296 * doc/autoconf.texi (autoreconf Invocation): Likewise.
17298 2002-09-26 Akim Demaille <akim@epita.fr>
17300 Single suffix rules and seperated dependencies are not portable.
17302 * doc/autoconf.texi (Installation Directory Variables): Update.
17303 (Limitations of Make): Some about `Single Suffix Rules and
17304 Separated Dependencies'.
17305 * bin/Makefile.am (autoconf, autoheader, autoreconf, autoupdate)
17306 (ifnames, autoscan, autom4te): Un-factor into several rules.
17308 2002-09-25 Paul Eggert <eggert@twinsun.com>
17310 * BUGS (Interoperability bugs): New section. Mention libtool
17311 1.4.2, configure.ac, and AC_CONFIG_AUX_DIR interoperability bug.
17313 2002-09-24 Paul Eggert <eggert@twinsun.com>
17315 Fix a portability bug reported by Alexandre Duret-Lutz: Solaris 8
17316 make handles suffix-rules differently from GNU make.
17318 * bin/Makefile.am (SUFFIXES, .in): Remove.
17319 (autoconf autoheader autoreconf autoupdate ifnames autoscan autom4te):
17320 Move the body of the old .in rule here.
17322 2002-09-16 Akim Demaille <akim@epita.fr>
17324 i960 compilers create `b.out' files by default.
17325 Reported by Ralf Corsepius.
17327 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT): Remove b.out files.
17328 (_AC_COMPILER_EXEEXT_DEFAULT): Adjust to b.out.
17330 2002-09-13 Paul Eggert <eggert@twinsun.com>
17332 * doc/autoconf.texi (Particular Headers): Remove obsolete
17333 reference to `struct timezone' in the description of
17336 2002-09-13 Akim Demaille <akim@epita.fr>
17340 * config/config.sub, config/config.guess: Update.
17341 * Makefile.maint: Update from bits of the Coreutils 4.5.1.
17342 * Makefile.am: Adjust.
17344 2002-09-13 Akim Demaille <akim@epita.fr>
17346 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Suggest
17347 reading config.log when the compiler is rejected.
17348 Suggested by Guido Draheim.
17350 2002-09-13 Akim Demaille <akim@epita.fr>
17352 * bin/autoreconf.in: Don't use Cwd::chdir, since in its internals
17353 (chdir_init) might hang when stat'ing mounted directories.
17354 Reported by Vance Shipley.
17356 2002-09-12 Akim Demaille <akim@epita.fr>
17358 * bin/autoscan.in (&parse_args): Pass a reference to the lists, not
17361 2002-09-12 Akim Demaille <akim@epita.fr>
17363 * doc/autoconf.texi (Defining Symbols): Present two different
17364 prototypes for AC_DEFINE and AC_DEFINE_UNQUOTED to emphasize the
17365 difference between 1 argument calls, and 2-3 argument calls.
17367 2002-09-12 Peter Eisentraut <peter_e@gmx.net>
17369 * doc/autoconf.texi: Review grammar and punctuation.
17371 2002-09-11 Paul Eggert <eggert@twinsun.com>
17373 * doc/autoconf.texi: Fix minor formatting, spelling, and
17375 (Defining Symbols): Explain that AC_DEFINE(var) defaults to 1, but
17376 AC_DEFINE(var,,description) does not; and the AC_DEFINE(var) case
17379 2002-09-11 Akim Demaille <akim@epita.fr>
17381 * doc/autoconf.texi (Questions): Rename as...
17383 (Defining Directories): New.
17385 2002-09-09 Akim Demaille <akim@epita.fr>
17387 * doc/autoconf.texi (Making testsuite Scripts): Update.
17388 Suggested by Nishio Futoshi.
17390 2002-09-09 Koji Arai <JCA02266@nifty.ne.jp>
17392 * doc/autoconf.texi (Making testsuite Scripts): Use `@@' where a
17393 plain `@' is wanted.
17395 2002-09-09 Akim Demaille <akim@epita.fr>
17397 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Keep the
17398 `duplicates', since the algorithm was too naive and could keep
17399 `--prefix=1 --prefix=2 --prefix=1' as `--prefix=1 --prefix=2', and
17400 keep `--prefix foo --prefix bar' as `--prefix foo bar'.
17401 Reported by Ralf Corsepius.
17402 * tests/torture.at (Configuring subdirectories): Exercise these
17405 2002-09-09 Akim Demaille <akim@epita.fr>
17407 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Use $srcdir when
17408 looking for a replacement file.
17409 * lib/autoconf/general.m4 (AC_CHECK_DECLS): Check that the
17410 directory is relative.
17411 * doc/autoconf.texi (Generic Functions): Clarify the replacement
17412 directory definition.
17413 Reported by Andreas Schwab and Jim Meyering.
17415 2002-09-06 Akim Demaille <akim@epita.fr>
17417 * doc/autoconf.texi (Setting Output Variables): Clarify what
17418 precious variables are.
17419 Suggested by Pontus Skoeld.
17421 2002-09-05 Akim Demaille <akim@epita.fr>
17423 * bin/Makefile.am (autoconf, autoheader, autoreconf, autoupdate)
17424 (ifnames, autoscan, autom4te): Since we don't only depend on
17425 configure.ac variables (such as VERSION etc.), but also on prefix
17426 and so forth, depend on Makefile, not configure.ac.
17427 Reported by Alexandre Duret-Lutz.
17428 * doc/autoconf.texi (Installation Directory Variables): Adjust.
17430 2002-09-05 Kevin Ryde <user42@zip.com.au>
17432 * doc/autoconf.texi (Limitations of Make): HP-UX trailing backslashes
17433 doesn't seem to be confined to ia64, just say "some versions".
17435 2002-09-04 Akim Demaille <akim@epita.fr>
17437 * Makefile.am, doc/Makefile.am: Remove pdf targets, handled by
17439 * Makefile.am (maintainer-clean-local): Remove.
17440 (MAINTAINERCLEANFILES): Remove COPYING.
17442 2002-09-03 Paul Eggert <eggert@twinsun.com>
17444 * doc/autoconf.texi (Configuration Commands): Remove obsolete
17445 example for AC_CONFIG_COMMANDS_PRE. Problem reported by Marcus
17448 2002-09-03 Akim Demaille <akim@epita.fr>
17450 * configure.ac: Bump to 2.53d.
17451 * Makefile.am (AUTOMAKE_OPTIONS): Require 1.6c, i.e., CVS Automake
17452 as of today, on Automake's team suggestion.
17454 2002-09-03 Akim Demaille <akim@epita.fr>
17458 2002-09-02 Akim Demaille <akim@epita.fr>
17460 * bin/autom4te.in (parse_args): Don't honor AUTOM4TE_PATH and
17462 * configure.ac: Disable SITE_MACRO_DIR.
17464 2002-09-02 Jim Meyering <meyering@lucent.com>
17466 * doc/autoconf.texi (AC_SYS_POSIX_TERMIOS): Reflect renaming: s/am/ac/,
17467 i.e., change am_cv_sys_posix_termios to ac_cv_sys_posix_termios.
17468 Also, tweak grammar: s/make sure to/be sure to/.
17470 2002-09-02 Paul Eggert <eggert@twinsun.com>
17472 * doc/autoconf.texi (Limitations of Builtins): Explain why logical
17473 directory names are generally preferable to physical names.
17475 2002-09-02 Akim Demaille <akim@epita.fr>
17477 * lib/Autom4te/General.pm (&update_file): s/die/error/.
17478 Reported by Raja R. Harinath.
17479 * bin/autoheader.in, bin/autoreconf.in, bin/autoscan.in,
17480 * bin/autoupdate.in: Use error instead of die.
17482 2002-09-01 Paul Eggert <eggert@twinsun.com>
17484 * tests/mktests.sh (ac_exclude_egrep, au_exclude_egrep): Use
17485 ordinary shell concatenation rather than echo+tr+sed command that
17486 runs afoul of a long-line-related sed bug in Solaris 8.
17488 * bin/autoheader.in (parse_args): --warning -> --warnings.
17490 * bin/autoconf.as: Work even if "ls" outputs "FOO not found" to
17491 stdout, as traditional "ls" does.
17492 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT,
17493 _AC_COMPILER_EXEEXT_O): Likewise.
17494 * doc/autoconf.texi (Limitations of Usual Tools): Add "ls".
17496 * bin/autoconf.as: Add --prepend-include option. This patch was
17497 applied to bin/autoconf.in in the 2002-07-17 patch by Mark D. Roth,
17498 but bin/autoconf.in is generated automatically from bin/autoconf.as.
17500 * bin/autoconf.in, configure: Regenerate.
17502 * doc/autoconf.texi (Special Shell Variables): Mention
17503 ENV, MAIL, MAILPATH, PS1, PS2, PS4. Index PWD.
17505 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Unset ENV, MAIL,
17506 MAILPATH and set PS1, PS2, PS4 to default values, to work
17507 around bug in pre-3.0 UWIN ksh reported by Bruce Lilly.
17508 For LC_ALL etc, first try to set to "C" as POSIX requires and as
17509 the Autoconf documentation specifies; fall back to "unset" only if
17510 this fails. Use a shell for-loop for this rather than an m4 loop,
17511 to shorten the output script.
17513 2002-08-30 Paul Eggert <eggert@twinsun.com>
17515 * doc/autoconf.texi (Special Shell Variables): Mention POSIX
17516 1003.1-2001's requirements for CDPATH. Give a simpler workaround
17517 for the CDPATH problem. Document PWD.
17518 (Limitations of Builtins): Document the problem that "cd $foo" and
17519 "ls $foo" may refer to different directories in shells conforming
17520 to POSIX 1003.1-2001. Use PS1 rather than CDPATH for "unset"
17521 example, since the old example is now out of date.
17523 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Reject FOO if "cd
17524 FOO" and "ls FOO" talk about different directories; this catches
17525 problems when POSIX 1003.1-2001 "cd" fails due to symlink
17528 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Use AS_UNSET instead
17529 of rolling our own unset.
17530 (_AS_PREPARE): $as_unset CDPATH instead of AS_UNSETting it, since
17531 in practice we needn't worry about CDPATH if unset doesn't work.
17533 * Makefile.in, aclocal.m4, bin/Makefile.in,
17534 config/Makefile.in, doc/Makefile.in, lib/Makefile.in,
17535 lib/Autom4te/Makefile.in, lib/autoconf/Makefile.in,
17536 lib/autoscan/Makefile.in, lib/autotest/Makefile.in,
17537 lib/emacs/Makefile.in, lib/m4sugar/Makefile.in, man/Makefile.in,
17538 tests/Makefile.in: Regenerate with Automake 1.6.3.
17540 * config/config.guess, config/config.sub, config/mkinstalldirs:
17543 * configure: Regenerate with self.
17545 2002-08-30 Kevin Ryde <user42@zip.com.au>
17547 * doc/autoconf.texi (Limitations of Usual Tools): Notes on "cc"
17550 2002-08-29 Rainer Orth <ro@TechFak.Uni-Bielefeld.DE>
17552 * bin/autom4te.in (Request::load): Correctly test for "do" read
17555 2002-08-29 Akim Demaille <akim@epita.fr>
17557 * lib/Autom4te/General.pm (&xqx): New.
17558 (&xsystem): Use WIFEXITED and WEXITSTATUS instead of decoding $? by
17559 hand, which is not portable.
17561 * bin/autom4te.in: Use them.
17562 Use &error instead of die.
17563 * tests/m4sugar.at (m4_warn, m4_require: circular dependencies):
17566 2002-08-17 Paul Eggert <eggert@twinsun.com>
17568 * lib/autoconf/fortran.m4 (AC_PROG_F77): Remove fc from the
17569 default list of compilers to try, since it was long ago superseded
17570 by the ksh fc builtin. Suggested by Steven G. Johnson.
17572 2002-07-31 Alexandre Duret-Lutz <duret_g@epita.fr>
17574 * doc/autoconf.texi (Invoking autom4te): End the option table,
17575 fixing a bug introduced by the previous patch.
17576 (Limitations of Make): Add a 'target lookup' subentry in the
17577 'VPATH' entry. Rewrite all `make' occurences as `@command{make}'.
17579 2002-07-29 Mark D. Roth <roth@feep.net>
17581 * bin/autom4te.in: Remove --include-envvar and --site-macro-subdir
17582 options and use $AUTOM4TE_PATH.
17583 * doc/autoconf.texi: Remove documentation of autom4te
17584 --include-envvar and --site-macro-subdir options and document
17585 use of $AUTOM4TE_PATH.
17586 * lib/autom4te.in: Remove --include-envvar and --site-macro-subdir
17587 arguments from each language section.
17589 2002-07-29 Paul Eggert <eggert@twinsun.com>
17591 * doc/install.texi: Include copyright symbol in copyright notice.
17593 * Makefile.am (MAKEINFO): Remove; it's a user-specified macro.
17595 (AM_MAKEINFOFLAGS): New macro.
17596 * doc/Makefile.am (MAKEINFO, AM_MAKEINFOFLAGS): Likewise.
17597 * Makefile.am (INSTALL): Use the new macros.
17598 Use -o rather than --output, since "missing" does not grok --output.

17886 This improves on an earlier suggestion by H. Peter Anvin.
17888 2002-05-16 Paul Eggert <eggert@twinsun.com>
17890 AC_FUNC_FNMATCH now tests only for POSIX compatibility.
17891 AC_FUNC_FNMATCH_GNU also tests for GNU extensions.
17892 Both macros now accept an optional source-dir arg.
17893 New macro AC_GNU_SOURCE to define _GNU_SOURCE.
17895 * NEWS: Document this.
17896 * doc/autoconf.texi (Particular Functions, UNIX Variants): Likewise.
17898 * lib/autoconf/functions.m4 (_AC_FUNC_FNMATCH): New macro.
17899 (AC_FUNC_FNMATCH): Use it. Test only for POSIX conformance,
17900 not for GNU extensions; this undoes part of the 2000-11-03 change,
17901 reverting to 2.13-compatible behavior.
17902 Add new optional argument DIR.
17903 (AC_FUNC_FNMATCH_GNU): New macro.
17905 * lib/autoconf/specific.m4 (AC_GNU_SOURCE): New macro.

17909 * lib/autoconf/headers.m4 (AC_HEADER_TIOCGWINSZ):
17910 Don't require AC_SYS_POSIX_TERMIOS. The test is unnecessary,
17911 and it causes a 'test' syntax error if it fails.
17912 Bug reported by Stephen Gildea.
17914 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
17915 If prototypes are supported, use them to check this at compile-time,
17916 instead of trying to check it at run-time. If we must do a run-time
17917 check, assume that setvbuf is standard when cross-compiling, as
17918 nonstandard setvbuf occurs only on ancient and unlikely hosts.
17919 Bug reported by Paul D. Smith.
17921 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Add optional
17922 argument specifying location of getloadavg.c. This removes a
17923 FIXME. This idea was taken from Jim Meyering's implementation in
17925 * doc/autoconf.texi (Particular Functions): Document this.
17926 Also, mention HAVE_NLIST_H rather than NLIST_STRUCT, since
17927 that's what the code does; this fixes a bug reported by

17932 * bin/autoreconf.in (autoreconf): Rewrite to use Gettext's
17933 autopoint instead of gettextize.
17934 ($uses_alocal): Rename as...
17935 ($uses_aclocal): this.
17936 * doc/autoconf.texi (autoreconf Invocation): Adjust.
17937 Suggested by Bruno Haible.

17943 2002-04-29 Paul Eggert <eggert@twinsun.com>
17945 * bin/autoreconf.in (autoreconf): Don't age aclocal.m4's input
17946 files to be 1 second older; just set them to be the same time.
17947 Also, sleep 1 second after the first aclocal, to work around
17948 problems with sub-second time stamps on the input files.
17950 2002-04-29 Thien-Thi Nguyen <ttn@gnu.org>
17952 * doc/autoconf.texi: Mention "set -e -x" lossage

17959 From Christian Cornelssen.
17961 2002-04-29 Akim Demaille <akim@epita.fr>
17963 * tests/m4sh.at (LINENO): If testsuite itself is rewritten because
17964 of lack of $LINENO support, then the test will compare the $LINENO
17965 in testsuite vs. the lineno in the test file. This is wrong, of
17967 Be sure to protect it.
17968 Reported by Patrick Welche.
17970 2002-04-25 Akim Demaille <akim@epita.fr>
17972 * doc/autoconf.texi (Obsolete Macros): Typo.
17973 Reported by Vladimir Volovich.
17975 2002-04-25 Akim Demaille <akim@epita.fr>
17977 * bin/autoreconf.in (autoreconf): Don't let aclocal.m4 be older
17978 than some of the input files, hence, on the second run of aclocal,
17979 if some of its input are younger, make them older.
17980 Suggested by Paul Eggert.
17982 2002-04-25 Akim Demaille <akim@epita.fr>
17984 * doc/autoconf.texi (Limitations of Usual Tools): sed and `!'.

17990 and ac_subst_vars be sh variables containing the list of
17991 AC_SUBST_FILES'ed and AC_SUBST'ed identifiers. Output them in the
17993 (_AC_INIT_PREPARE): Use them to log them.
17994 (_AC_SUBST, _AC_SUBST_SED_PROGRAM): Remove.
17995 (AC_SUBST, AC_SUBST_FILE): Instead of buliding the
17996 _AC_SUBST_SED_PROGRAM, store the list of output files/variables in
17997 _AC_SUBST_FILES and _AC_SUBST_VARS.
17998 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Adjust.
18000 2002-04-24 Akim Demaille <akim@epita.fr>
18002 * bin/autoreconf.in (autoreconf): Run automake after autoconf and
18003 autoheader, so that automake does not complain about a missing
18004 config.h.in that was to be created.
18006 2002-04-23 Akim Demaille <akim@epita.fr>

18088 that is not portable to Zsh.
18090 2002-04-19 Alexandre Duret-Lutz <duret_g@epita.fr>
18092 * bin/autoupdate.in (handle_autoconf_macros): Honor AU_DEFUNs
18093 from aclocal.m4 too.
18095 2002-04-12 Akim Demaille <akim@epita.fr>
18097 * tests/wrappl.as: New, M4sh precursor of wrappl.in.
18099 2002-04-10 Akim Demaille <akim@epita.fr>
18101 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Install the Zsh
18102 workaround for ${1+"$@"}.
18103 * doc/autoconf.texi (Shell Substitutions): Explain it.
18104 From Oliver Kiddle and Peter Stephenson.
18106 Have M4sh perform minimal shell sanitizing.
18108 * lib/m4sugar/m4sh.at (AS_SHELL_SANITIZE): Split the `_AS_PREPARE_*'
18110 (_AS_PREPARE): this new macro.
18112 (AS_INIT): Invoke AS_SHELL_SANITIZE.
18113 * tests/m4sh.at (AT_DATA_LINENO): Use _AS_PREPARE.
18115 Adjust Autoconf and Autotest.
18117 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Don't invoke
18118 AS_SHELL_SANITIZE, AS_INIT did it, but invoke AS_PREPARE.
18119 * lib/autotest/general.m4 (AT_INIT): Likewise.
18120 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
18121 Invoke _AS_PREPARE (not AS_PREPARE) in addition to
18124 Use this M4sh to generate Autoconf's shell scripts.
18126 * tests/wrapsh.as: New, precursor of wrapsh.in.
18127 * tests/Makefile.am: Include lib/freeze.mk to get the dependencies
18128 on Autotest and M4sh.
18129 ($(TESTSUITE)): Use $(autotest_m4f_dependencies).
18130 (wrapsh.in): New target.
18131 * bin/autoconf.as: New, precursor of autoconf.in.
18132 (autoconf.in): New target.
18134 2002-04-09 Alexandre Duret-Lutz <duret_g@epita.fr>

18137 with indented comments in rules.

18152 directories when descending in a SUBDIRS.
18153 Reported by Ezra Peisach.
18155 2002-04-04 Andreas Schwab <schwab@suse.de>
18157 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Only simplify if path
18158 contains no literal separators.
18160 2002-04-03 Akim Demaille <akim@epita.fr>
18162 * lib/autoconf/status.m4 (_AC_CONFIG_FILE, _AC_CONFIG_HEADER)
18163 (_AC_CONFIG_COMMAND, _AC_CONFIG_LINK): New.
18164 Use dnl, not the KILL diversion.
18166 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_COMMANDS)
18167 (AC_CONFIG_LINKS): here.
18169 Don't use the KILL diversion, as it kills spurious output, which
18170 results in failures being hidden.
18171 Use m4_defn where appropriate.
18172 (AC_CONFIG_IF_MEMBER): Kill the real bug: a spurious parenthesis
18173 after the second argument.
18175 * lib/autom4te.in (Autoconf, Autotest, M4sh): Don't pass --warning
18176 syntax, as it is provided by M4sugar.
18177 * tests/torture.at (Multiple AC_CONFIG_FILES): New.
18179 2002-04-03 Andreas Schwab <schwab@suse.de>
18181 * lib/m4sugar/m4sugar.m4 (m4_bmatch): Make sure m4_bregexp is not
18182 expanded if $# <= 2.

18193 (_AC_COMPILER_OBJEXT): Use them.
18194 Fixes Debian #138666.
18196 2002-04-02 Peter Eisentraut <peter_e@gmx.net>
18198 Integrate AC_PROG_CC_STDC into AC_PROG_CC.
18200 * lib/autoconf/c.m4 (AC_PROG_CC_STDC): Rename to _AC_PROG_CC_STDC.
18201 AU_DEFUN old name. Use _AC_COMPILE_IFELSE.
18202 (AC_PROG_CC): Call _AC_PROG_CC_STDC.
18203 (AC_C_INLINE): Do not require AC_PROG_CC_STDC.
18204 (AC_C_CONST): Same.
18205 (AC_C_INLINE): Same.

18214 _AS_MKDIR_P_PREPARE.
18216 2002-03-28 Kevin Ryde <user42@zip.com.au>
18218 * lib/autoconf/c.m4 (AC_C_INLINE): Test with a typedef return value,
18219 to avoid versions of HP C which don't allow that.
18221 2002-03-27 Paul Eggert <eggert@twinsun.com>
18223 * lib/m4sugar/m4sh.m4 (_AS_BASENAME_PREPARE): New macro.
18224 (AS_SHELL_SANITIZE): Invoke it.
18225 (AS_BASENAME): AS_REQUIRE it, and use $as_basename.

18229 * doc/autoconf.texi (Portable Shell): Add pointers to FAQs.
18231 2002-03-26 Akim Demaille <akim@epita.fr>
18233 * doc/autoconf.texi (Introduction): The GNATS base moved.
18235 2002-03-25 Paul Eggert <eggert@twinsun.com>
18237 * tests/m4sh.at: Don't rely on "PATH=test:$PATH test-1" working
18238 as POSIX requires, as it doesn't work with Zsh.
18239 * doc/autoconf.texi (Assignments): Document the problem.
18241 2002-03-25 Alexandre Duret-Lutz <duret_g@epita.fr>
18243 * doc/autoconf.texi (Limitations of Make): Mention more issue
18244 about VPATH, overriding of macros in sub-makes, and handling of
18247 2002-03-21 Paul Eggert <eggert@twinsun.com>
18249 * doc/autoconf.texi (Here-Documents): Mention Solaris 8 dtksh
18250 problem with here-document buffer boundaries.
18252 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Unset ENV and BASH_ENV
18253 when reinvoking the shell, to work around problems with installers
18254 who put strange things like "cd" commands in their environments.
18256 2002-03-19 Akim Demaille <akim@epita.fr>
18258 * tests/semantics.at (AC_C_BIGENDIAN): s/unknow/unknown/.

18270 From Nishio Futoshi.
18272 2002-03-19 Akim Demaille <akim@epita.fr>
18274 * lib/m4sugar/m4sugar.m4 (m4_define_default, m4_fst, m4_map): New.

18278 * doc/autoconf.texi (Programming in M4sh): Add AS_MKDIR_P.
18279 (Limitations of Usual Tools): Add mkdir section.
18281 * lib/m4sugar/m4sh.m4 (_AS_MKDIR_P_PREPARE): New macro.
18282 (AS_MKDIR_P): Require it. Use mkdir -p if available, falling
18283 back on AS_DIRNAME to compute prefixes otherwise; this is
18284 roughly what mkinstalldirs does. That way, we need not have
18285 our own filename disassembler. The old disassembler did not
18286 work with Solaris 8 dtksh, which is ksh Version M-12/28/93d.
18288 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP):
18289 Create at_test_all by a series of assignments,
18290 not by a single assignment of a long string. The latter causes ksh
18291 version 11/16/88g to silently misbehave on OpenServer 5.0.6a,
18292 presumably because of a buffer overrun.
18294 2002-03-14 Paul Eggert <eggert@twinsun.com>
18296 * lib/autotest/general.m4 (at_times_skip):
18297 Renamed from at_times. Now a boolean.
18298 ksh93 Version M-12/28/93d doesn't like 'x=times; $x'; it
18299 says 'times: not found'.
18301 2002-03-14 Akim Demaille <akim@epita.fr>
18303 * bin/autoreconf.in (&study_gettextize): New.
18304 (&autoreconf): Handle newest gettextize.

18328 2002-03-11 Andreas Schwab <schwab@suse.de>
18330 * configure.ac: Explicitly check for EMACS since AM_PATH_LISPDIR
18331 does not do it if --with-lispdir is given.

18340 subdirectory should exist.
18342 2002-03-08 Akim Demaille <akim@epita.fr>
18344 * Makefile.am (AUTOMAKE_OPTIONS): 1.6.
18346 2002-03-08 Akim Demaille <akim@epita.fr>
18348 * bin/autom4te.in (&handle_m4): Do not foreach with `$_' as it
18349 aliases the actual variables, and modifications of the former
18352 2002-03-08 Akim Demaille <akim@epita.fr>
18354 * bin/autom4te.in (&handle_m4): Protect us from corrupted file
18355 because of C-c: have m4 output in tmp files, then mv them.
18357 2002-03-08 Akim Demaille <akim@epita.fr>

18376 2002-03-04 Akim Demaille <akim@epita.fr>
18378 * doc/autoconf.texi (AC_LIBOBJ vs. LIBOBJS): New.
18379 * lib/autoconf/general.m4 (AC_INIT): More informative error
18380 message for LIBOBJ.
18382 2002-03-04 Akim Demaille <akim@epita.fr>
18384 * lib/freeze.mk ($(build_libdir)/m4sugar/version.m4): New, for
18387 2002-03-04 Akim Demaille <akim@epita.fr>
18389 * doc/autoconf.texi (Transforming Names): Equality between target
18390 and host is irrelevant.
18391 (Specifying Names, Canonicalizing): Remove all references to the
18392 backward compatibility hooks. Rather, collect them all into...
18393 (Hosts and Cross-Compilation): this new section.
18394 * doc/install.texi (System Type): Ditto.
18395 * lib/autoconf/general.m4 (AC_CANONICAL_HOST): Explicitly state
18396 that `--host' implies cross-compilation.
18398 2002-03-04 Akim Demaille <akim@epita.fr>
18400 * doc/autoconf.texi (Evaluation Macros): New.
18401 * lib/m4sugar/m4sugar.m4 (m4_lquote): Remove, it is totally
18403 (_m4_foreach): Define the variant with immediate evaluation so
18404 that it contains exactly the items, not an expression which
18405 evaluation is the current item.
18406 (m4_re_string, m4_re_word): Don't over quote them.
18408 2002-03-04 Akim Demaille <akim@epita.fr>
18410 Instead of having stacking `shift's evaluated at the end, let
18411 `foreach' loops immediately evaluate them.
18413 * lib/m4sugar/m4sugar.m4 (m4_quote, m4_dquote): Use $@ rather than
18414 $*. This is the n-th time I change my mind, but hopefully this is
18417 (m4_text_wrap): Use m4_foreach, which is finally correct _and_
18419 (m4_foreach_quoted, m4_car_quoted, _m4_foreach_quoted): Remove, as
18420 it was only a hack for m4_text_wrap.
18421 (m4_car2): Remove, replaced by...
18423 (_m4_foreach): Adjust.
18424 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Adjust, and use
18425 m4_bpatsubst for clarification.

18474 2002-02-07 Akim Demaille <akim@epita.fr>
18476 Fix Autoconf PR/207:
18477 AC_PREFIX_PROGRAM fails with dashed program names
18479 * lib/autoconf/general.m4 (AC_PREFIX_PROGRAM): Just use a fresh
18480 variable when looking for the prefix program.
18481 Now it also works for shell variables.

18491 case/esac, some shells don't support it.
18492 Reported by Zack Weinberg.

18497 * lib/autotest/general.m4 (AT_INIT): When handling --keywords, be
18498 sure not to introduce newlines in at_groups.

18516 2002-02-05 Akim Demaille <akim@epita.fr>
18518 * tests/Makefile.am (check_SCRIPTS): Use it, instead of WRAPPERS,

18535 * lib/autoconf/autoconf.m4, lib/autotest/general.m4,

18538 2002-02-05 Akim Demaille <akim@epita.fr>
18540 * bin/autom4te.in (&parse_args): Implement `frozen files are
18541 optional are the sum of the previous files on the command line'.
18542 Also, pass `--reload-state=' on them, so...
18543 (handle_m4): don't.
18544 * lib/autom4te.in (Autotest, Autoconf): Rely on M4sh.
18545 (M4sh): Rely on M4sugar.
18546 (Autotest, M4sh, M4sugar): Use frozen files.
18548 2002-01-31 Akim Demaille <akim@epita.fr>
18550 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Accept $4.

18553 2002-01-30 Akim Demaille <akim@epita.fr>
18555 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Map non
18556 alphanumeric to `-' instead of `_'.
18558 2002-01-30 Akim Demaille <akim@epita.fr>
18560 * tests/semantics.at (AC_CHECK_SIZEOF): Split into two tests: one
18561 for plain code, the other for cross-compilation code. The latter
18562 is now run with GCC only.
18563 * doc/autoconf.texi (Compilers and Preprocessors): New.

18570 change AC_INIT default values.
18572 2002-01-29 Akim Demaille <akim@epita.fr>
18574 * tests/torture.at (Configuring subdirectories): Use configure.in,
18575 so that aclocal 1.4 works.
18576 Reported by Alexandre Duret-Lutz and Larry Schmitt.
18578 2002-01-28 Akim Demaille <akim@epita.fr>
18580 * doc/autoconf.texi (Writing testsuite.at): AT_CLEANUP no longer
18583 2002-01-28 Akim Demaille <akim@epita.fr>
18585 * lib/autotest/general.m4 (AT_INIT): Don't be ridiculous: adjust
18586 AUTOTEST_PATH *after* it was set.
18587 Don't put `.' in the PATH: the user should be precise and `./' if
18588 needed. In addition, given that the test suite does some `cd', if
18589 `.' is in the path, the `tested programs' sections will report
18590 programs found in the test suite's directory, while during the
18591 tests (performed in their own directory), these programs are no
18592 longer visible. In other words, the results is confusing and
18594 * tests/m4sh.at: Adjust: don't rely on `.' being in the PATH.

18639 message on invalid options.
18640 * bin/autom4te.in (parse_args): Don't use
18641 Autoconf::General::getopt with non valid options.

18659 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Don't create
18660 package.m4, since is really depends upon configure.ac, not
18662 * doc/autoconf.texi (testsuite Scripts): Adjust.
18663 * tests/Makefile.am (package.m4): New.
18664 EXTRA_DIST it since its a source.
18666 2002-01-06 Akim Demaille <akim@epita.fr>
18668 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Move the AC_SUBST
18669 of PACKAGE_NAME, PACKAGE_TARNAME, PACKAGE_VERSION, PACKAGE_STRING,
18670 and PACKAGE_BUGREPORT from here...
18671 (_AC_INIT_DEFAULTS): to here, since it is unrelated to the
18673 (_AC_INIT_PREPARE): AC_DEFINE these symbols.
18674 * lib/autotest/general.m4: Use AT_PACKAGE_*, not PACKAGE_*.

18698 2001-12-14 Akim Demaille <akim@epita.fr>
18700 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): We cleaning up the
18701 trailing files, don't apply `-rf' to files which might not be
18702 created by configure (core, core.*, and *.core), but just `rm -f'.
18703 Suggested by Jonathan Kamens.
18705 2001-12-14 Aaron M. Ucko <amu@alum.mit.edu>
18707 * lib/autoconf/general.m4: Avoid duplicates in `$ac_configure_args'.

18711 * Makefile.am (MAINTAINERCLEANFILES): Remove configure.
18713 2001-12-13 Peter Eisentraut <peter_e@gmx.net>

18716 abs_builddir, top_buildpath to abs_top_builddir, srcpath to
18717 abs_srcdir, top_srcpath to abs_top_srcdir.
18718 (_AC_OUTPUT_FILES): Adjust.
18719 * NEWS, doc/autoconf.texi, lib/autoconf/autotest.m4,
18720 * tests/atspecific.m4, tests/autoreconf.in, tests/tools.at,
18721 * tests/wrappl.in, tests/wrapsh.in: Adjust.
18723 2001-12-12 Steven G. Johnson <stevenj@alum.mit.edu>
18725 * lib/autoconf/fortran.m4 (_AC_PROG_F77_V_OUTPUT): Fix failed

18729 2001-12-12 Kevin Ryde <user42@zip.com.au>
18731 * doc/autoconf.texi (File Descriptors): Use a clearer layout for the
18732 forbidden file descriptors table.
18734 2001-11-26 Akim Demaille <akim@epita.fr>
18736 * bin/autoscan.in (%c_keywords): Build it at top level.
18737 Map to 1 in order to simplify its uses.
18739 2001-11-26 Akim Demaille <akim@epita.fr>
18741 * bin/autoscan.in (&scan_c_file, &scan_sh_file, &scan_makefile):
18742 Remove $filepath, useless.
18743 (&scan_makefile): Don't remove the $(FOO), ${FOO} and @FOO@
18744 variables, they are really part of the tokens.
18745 Split the input line on spaces and then look for tokens.
18746 Now autoscan ceases to ask for AC_PROG_LEX for the package Bison
18747 because of `lex$U.$(OBJEXT)'.
18748 (&scan_files): Use "@list" instead of join.
18749 * doc/Makefile.am (CLEANFILES): Add *.fns.
18751 2001-11-26 Akim Demaille <akim@epita.fr>

18754 Remove, replaced by...
18755 * tests/wrappl.in: Be common for all the Perl executables.
18756 In particular autoscan and autoheader want -I.
18757 * configure.ac: Adjust.
18758 * lib/autoscan/headers: errno.h is portable.
18760 2001-11-26 Akim Demaille <akim@epita.fr>
18762 * bin/autoscan.in (used): New.
18765 2001-11-26 Akim Demaille <akim@epita.fr>
18767 * bin/autoscan.in (&scan_c_file): Better parsing of CPP
18769 (&scan_sh_file): Remove a duplicate pattern.
18770 (&check_configure_ac): Use long options.

18775 * bin/autoscan.in (scan_c_file): Fix the handling of C comments.
18776 Before, having a line containing the opening of a multi line
18777 comment made the whole line be ignored.
18779 2001-11-26 Akim Demaille <akim@epita.fr>
18781 * doc/autoconf.texi (Using an Autotest Test Suite): New.

18787 Test groups are now run two directories deeper.
18789 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Replace srcdir,
18790 top_srcdir and top_builddir with at_srcdir, at_top_srcdir and
18792 * lib/autotest/general.m4 (AT_INIT): Compute srcdir,
18793 top_srcdir, builddir and top_builddir.
18794 Use `at_*dir' relatively to the directory containing the
18795 suite, use `*dir' when relatively to the current group dir.
18797 2001-11-25 Joseph S. Myers <jsm28@cam.ac.uk>
18799 * doc/autoconf.texi, TODO, lib/autoconf/fortran.m4,
18800 lib/autoconf/functions.m4, lib/autoconf/headers.m4,
18801 tests/atgeneral.m4, tests/tools.at, tests/atspecific.m4: Fix
18804 2001-11-22 Alexandre Duret-Lutz <duret_g@epita.fr>
18806 * doc/autoconf.texi (Using System Type): Add an example of `case
18807 $host' usage so people quit using `case $target' everywhere.
18809 2001-11-22 Akim Demaille <akim@epita.fr>
18811 * doc/autoconf.texi (Installation Directory Variables): Englishoes
18812 spotted by Jim Meyering.
18814 2001-11-16 Paul Eggert <eggert@twinsun.com>
18816 This patch implements a `long double' suggestion by Oliver Kiddle.
18818 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C)): Make the array
18819 static, to catch errors if the value isn't known at compile-time
18820 and the compiler supports dynamic arrays. Change its name from
18821 `_array_' to `test_array' to avoid potential name clashes.
18822 (AC_C_LONG_DOUBLE): Make it a compile-time test, not a run-time
18823 test. Do not define HAVE_LONG_DOUBLE if `long double' is no
18824 better than double. Catch a bug in GCC 2.95.2 x86.
18825 * doc/autoconf.texi (C Compiler): Document the above.
18828 2001-11-13 Akim Demaille <akim@epita.fr>
18830 * tests/m4sh.at (LINENO): Protect from autom4te's substitution by
18832 * tests/tools.at: Don't protect dnl, AT_DATA_M4SH does.
18834 2001-11-13 Akim Demaille <akim@epita.fr>
18836 * lib/autotest/general.m4 (AT_INIT): After having run the test
18837 group, go back to the initial directory, not to at_suite_dir.
18839 2001-11-13 Akim Demaille <akim@epita.fr>
18841 * tests/atspecific.m4 (AT_DATA_M4SUGAR, AT_DATA_M4SH)
18842 (AT_DATA_AUTOCONF): Also protect @&t@ from autom4te.
18843 (AT_CHECK_AUTOCONF, AT_CHECK_AUTOHEADER): Pass no --include
18845 (AT_CHECK_CONFIGURE): Use absolute paths.
18846 (_AT_CHECK_AC_MACRO): Create aclocal.m4 with AC_STATE_SAVE in it.
18847 The problem is still the old one: there is no means in M4 (that I
18848 know about) to create a defining macro, because there is no means
18849 to create `$1' etc., therefore, the defining macro ``swallows''
18850 all the arguments meant to the defined macro.
18852 2001-11-13 Akim Demaille <akim@epita.fr>
18854 * tests/atspecific.m4 (AT_DATA_AUTOCONF): New.
18855 (AT_CONFIGURE_AC): Output the definition of AC_STATE_SAVE in
18857 * tests/aclocal.m4: Remove, as it is no longer used.
18859 2001-11-13 Akim Demaille <akim@epita.fr>
18861 * lib/autotest/general.m4: Change `tests?' into `groups?' in
18862 variable names when referring to a single test group, or to
18863 `suite' when referring to the whole test suite.
18864 `at_last_test' is removed: m4 compute at_format itself.
18865 (at_stdout, at_stder1, at_stderr): New variables.
18866 (AT_CHECK): Use them.
18868 2001-11-13 Akim Demaille <akim@epita.fr>
18870 * lib/autotest/general.m4 (AT_INIT): Be sure to put `.', relative,
18872 Create `testsuite.dir/003/run' instead of `testsuite.003'.
18873 Do it as soon as a test fails, don't wait till the end of the test
18875 Don't remove $as_me.[0-9]*, since these files no longer exist.
18877 2001-11-13 Akim Demaille <akim@epita.fr>
18879 * tests/tools.at: Use absolute paths, since we are no longer run
18882 2001-11-13 Akim Demaille <akim@epita.fr>
18884 Now that tests are running in their own private dir, there is no
18885 need to list the files to remove at the end of tests groups.
18887 * lib/autotest/general.m4 (_AT_CLEANUP_FILE, AT_CLEANUP_FILES):
18888 (AT_data_files, at_data_files): Remove.
18889 (AT_CLEANUP, AT_DATA): Simplify.
18891 Remove the group dir if !debug && !failed.
18892 * tests/atspecific.m4: Adjust.
18894 2001-11-13 Akim Demaille <akim@epita.fr>
18896 Start a new layout for Autotest: `testsuite' creates
18897 `testsuite.dir' in which the at-check-line etc. files are to be
18898 found, and `testsuite.dir/003' where the test group 3 is run.
18900 * lib/autotest/general.m4 (AT_INIT): at_tests_dir,
18901 at_check_line_file, at_format, at_test_normalized, at_group_dir
18903 Create the directories.
18904 Use absolute paths for at- files.
18905 (AT_CHECK): Adjust.
18907 2001-11-11 Michael Matz <matz@kde.org>
18909 * m4sugar.m4 (_m4_foreach): Make it linear instead quadratic.
18911 (m4_car): Properly quote arguments.
18913 2001-11-13 Akim Demaille <akim@epita.fr>
18915 * tests/aclocal.m4 (AC_STATE_SAVE): s/LIBOBJS/LIB@&t@OBJS/ to cope
18916 with stricter rules on LIBOBJS.
18918 2001-11-12 Paul Eggert <eggert@twinsun.com>
18920 * lib/autoconf/c.m4 (AC_C_PROTOTYPES): Define __PROTOTYPES too.
18921 * doc/autoconf.texi (C Compiler): AC_C_PROTOTYPES now defines
18924 2001-11-12 Akim Demaille <akim@epita.fr>
18926 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT): Use AC_CHECK_FUNCS.
18928 2001-11-12 Akim Demaille <akim@epita.fr>
18930 * lib/autoconf/c.m4, lib/autoconf/fortran.m4,
18931 * lib/autoconf/functions.m4, lib/autoconf/general.m4,
18932 * lib/autoconf/headers.m4, lib/autoconf/libs.m4,
18933 * lib/autoconf/programs.m4, lib/autoconf/specific.m4,
18934 * lib/autoconf/types.m4: When invoking AC_DEFINE and friends,
18935 specify to what the macro should be defined (typically to 1).
18937 2001-11-12 Akim Demaille <akim@epita.fr>
18939 * lib/autoconf/functions.m4 (AC_FUNC_STRTOD): AC_SUBST POW_LIB.
18942 2001-11-12 Akim Demaille <akim@epita.fr>
18944 * lib/autoconf/programs.m4 (_AC_PROG_LEX_YYTEXT_DECL): Use
18945 AC_TRY_EVAL to run $LEX, not AC_TRY_COMMAND. This validates the
18946 definition used by Automake where LEX is +/- "${missing} lex" and
18947 `missing' itself contains variables.
18949 2001-11-12 Akim Demaille <akim@epita.fr>
18951 * lib/autotest/general.m4 (AT_INIT): Push KILL at the end.
18952 Now that M4sh pushes BODY, the comments were output at the end of
18955 2001-11-08 Akim Demaille <akim@epita.fr>
18957 * bin/autoreconf.in (&autoreconf): Run aclocal before tracing, so
18958 that we can trace macros from aclocal.m4.
18959 Trace AC_PROG_LIBTOOL, not AM_PROG_LIBTOOL, since the latter is
18960 obsoleted, and redirect to the former anyway.
18961 Reported by Ralf Corsepius.
18963 2001-11-08 Akim Demaille <akim@epita.fr>
18965 * bin/autoreconf.in (&autoreconf): AC_CONFIG_SUBIDRS are to be
18966 processed only if present.
18967 * tests/torture.at (Configuring subdirectories): Use autoreconf
18968 instead of successive calls to autoconf.
18969 Add a nonexistent subdirectory to exercise the patch above.
18970 Reported by Ralf Corsepius.
18972 2001-11-08 Kevin Ryde <user42@zip.com.au>
18974 * doc/autoconf.texi (Limitations of Usual Tools): Note HP-UX cc
18975 doesn't accept .S files.

18983 (handle_output): Use it.
18984 Read m4_pattern_forbid with messages.

18988 * bin/autom4te.in (--normalize): Remove.
18989 * lib/autom4te.in: Adjust.
18991 2001-11-05 Akim Demaille <akim@epita.fr>
18993 * tests/Makefile.am (testsuite): Rename this target as...
18994 ($(TESTSUITE)): this.
18997 2001-11-05 Alexandre Duret-Lutz <duret_g@epita.fr>
18999 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): When removing
19000 the --prefix option, also remove it's argument.
19002 2001-11-05 Akim Demaille <akim@epita.fr>
19004 * doc/autoconf.texi (testsuite Invocation): Update.
19005 (Writing testsuite.at): Update.

19014 (&file_name_is_absolute): New, wrappers around routines from
19016 Use and export them.
19017 (&find_configure_ac): Optionally take a directory where to look at.
19018 * bin/autoreconf.in (&parse_args): Trim the configure.ac part of
19020 Default @ARGV to `.', not find_configure_ac.
19021 (&autoreconf): Argument is a directory.
19022 Trace AC_CONFIG_SUBDIRS and schedule the subdirs for autoreconf'ing.
19023 * doc/autoconf.texi (autoreconf Invocation): Update.
19025 2001-11-03 Akim Demaille <akim@epita.fr>

19029 Add basename, dirname, and fileparse.
19031 * bin/autoreconf.in (&autoreconf): Fix call to fileparse.
19032 Don't look for aclocal flags if we already know aclocal is not
19034 Move aclocal.m4t only if it exists.
19035 Reported by Ezra Peisach.
19037 2001-11-03 Akim Demaille <akim@epita.fr>
19039 * bin/autoreconf.in (&parse_args): Work only on the configure.ac
19040 passed on command line, defaulting to ./configure.ac if present.
19041 (&maybe_autoreconf, File::Find): Remove, unused.
19042 (&autoreconf): If autoconf is not used, don't try to trace.
19044 2001-11-02 Akim Demaille <akim@epita.fr>

19061 Don't run aclocal when aclocal.m4 is not from aclocal.
19063 Don't run libtoolize and gettextize if --install is not given.
19065 2001-11-01 Paul Eggert <eggert@twinsun.com>
19067 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): _AS_CR_PREPARE needs to
19068 be invoked before _AS_LINENO_PREPARE.
19069 (_AS_LINENO_PREPARE): Use as_cr_digits and as_cr_alnum rather
19070 than character ranges.
19072 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Fix NLS before
19073 invoking AS_BASENAME. Set the locale variables to 'C' if
19074 possible, as POSIX requires this to get the traditional

19078 2001-10-31 Paul Eggert <eggert@twinsun.com>
19080 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): Do not surround body
19081 with {}, as that triggers a bug in Bash 2.05.
19083 (_AS_LINENO_PREPARE): Use Sed rather than
19084 Awk. Fix the sed prepass to work even if there are multiple
19085 instances of $LINENO on the same line. Do not substitute for
19086 other variables like $LINENOT. Do not check file dates; such a
19087 check is unreliable on sufficiently fast machines, and removing
19088 the check makes the code simpler and more reliable. Check for
19089 output and chmod failures.
19091 * doc/autoconf.texi (Special Shell Variables): Document
19094 2001-10-31 Akim Demaille <akim@epita.fr>

19106 2001-10-26 Paul Eggert <eggert@twinsun.com>
19108 * NEWS, README, configure.ac, lib/Autom4te/General.pm,
19109 lib/Autom4te/Struct.pm:
19110 Require Perl 5.005_03 instead of just 5.005, as some tests fail

19114 more LINENO gotchas, particularly with respect to the Awk+Sed hack.
19116 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): New macro.
19117 (_AS_LINENO_PREPARE): Use it instead of shell eval, since

19136 * lib/autoconf/functions.m4 (AC_FUNC_STRERROR_R):
19137 Rename ac_cv_func_strerror_r_works to ac_cv_func_strerror_r_char_p,
19138 and rename HAVE_WORKING_STRERROR_R to STRERROR_R_CHAR_P, since
19139 POSIX decided to standardize on the int flavor of strerror_r.
19140 Always do char* test, as there's no reason not to.
19141 Assign to a char* var, to catch strerror_r that returns int*.
19143 * doc/autoconf.texi (Particular Functions):
19144 Document the above changes. Also, document the fact that
19145 AC_FUNC_STRERROR_R defines HAVE_DECL_STRERROR_R.

19169 * bin/autoheader.in ($localdir, $m4, $SIMPLE_BACKUP_SUFFIX):
19171 * bin/autoreconf.in (&autoreconf): Do not run gettextize when
19172 `intl' is already present, as it refuses unless --force.
19173 (&parse_args): Use -I, --include instead of the old Autoconf
19175 ($localdir, $autoconf_dir): Remove.
19177 (&maybe_autoreconf): New, to preserve $_ for File::Find.
19179 2001-10-19 Jens Petersen <petersen@redhat.com>

19200 configure.ac being studied.
19202 2001-10-18 Paul Eggert <eggert@twinsun.com>
19204 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Cast sizeof to unsigned

19209 (AS_BASENAME_EXPR): New macro.
19210 (AS_BASENAME_SED): Do not assume GNU sed semantics.
19211 (AS_BASENAME): Use 'basename' if that works; then try 'expr';
19212 and fall back on 'sed' only if the other two fail. This makes
19213 AS_BASENAME act more like AS_DIRNAME.
19214 (as_me): Shell-quote the argument of AS_BASENAME, in case $0
19215 contains white space.
19216 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR):
19217 Use AS_DIRNAME, since I think it's now DOS-friendly.

19273 2001-10-08 Akim Demaille <akim@epita.fr>

19366 * tests/Makefile.am (clean-local): Don't invoke $(TESTSUITE) if it

19451 (_AC_COMPUTE_INT): Pass IF-FAILS arg to _AC_COMPUTE_INT_COMPILE.

19592 * tests/Makefile.am (package.m4): Remove.
19594 2001-09-22 Akim Demaille <akim@epita.fr>
19596 Rely on `$LINENO' when possible instead of `__oline__'.

19599 `$LINENO' support replacement when not supported.
19600 (_AS_CR_PREPARE, _AS_TR_CPP_PREPARE, _AS_TR_SH_PREPARE): Invoke

19645 arguments. Fixed a typo.
19647 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
19649 * man/Makefile.am (.x.1): Use @PATH_SEPARATOR@, not ':' to set up
19650 $PATH. Also set AUTOM4TE_CFG, so we can process autom4te properly.
19652 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
19654 * bin/autoscan.in: Add 'exec-perl-if-not-run-by-perl'.

19663 * lib/Autom4te/XFile.pm (open): Simplified the error message (we
19664 already have $file). Set output files to binary mode (helps avoid
19665 CR issues on DOSish systems).
19667 2001-09-19 Akim Demaille <akim@epita.fr>
19669 * lib/autotest/general.m4: Englishoes.
19670 From Tim Van Holder and Alexey Mahotkin.
19672 2001-09-18 Paul Eggert <eggert@twinsun.com>
19674 * doc/autoconf.texi (Common Shell Constructs): New node,
19675 documenting AS_DIRNAME.
19676 (Limitations of Usual Tools): Refer to it when discussing dirname.
19677 Also, update discussion of POSIX standard to reflect latest draft.
19679 * lib/autoconf/c.m4:
19680 (AC_LANG_INT_SAVE(C)): Also support negative values, down to LONG_MIN.
19682 * lib/autoconf/general.m4 (_AC_COMPUTE_INT_COMPILE):
19683 Do not pass a first argument with leading '-'
19684 to expr, by parenthesizing initial integers that might be negative.
19686 * doc/autoconf.texi (Particular Functions): AC_FUNC_GETPGRP
19687 now merely checks whether it is an error to pass an argument
19690 * lib/autoconf/functions.m4 (_AC_FUNC_GETPGRP_TEST): Remove.
19691 (AC_FUNC_GETPGRP): Don't bother with a runtime test. Just check
19692 whether it is a (compile-time) error to pass an argument to
19693 getpgrp. This simpler test supports the revised documentation,
19694 and is all that AC_FUNC_GETPGRP's users really need.
19696 2001-09-18 Akim Demaille <akim@epita.fr>
19698 * doc/autoconf.texi (Limitations of Make) <$<>: New.

19708 * tests/m4sh.at: Ensure that AS_DIRNAME handles '/', '//' and '///'
19710 Add test for AS_BASENAME.
19711 * lib/m4sugar/m4sh.m4: Fix AS_BASENAME so that it passes the previous
19712 added test. It now correctly handles /1/2/3/, returning '3' not ''.
19713 Added AS_BASENAME_SED to make the interface the same as AS_DIRNAME.
19714 * tests/base.at: Fixed the expected responses. The old ones were
19716 * lib/autoconf/general.m4: Fixed AC_PREFIX_PROGRAM, it now behaves as
19717 the documentation claims it should (and how it behaved in 2.13).
19719 2001-09-18 Akim Demaille <akim@epita.fr>
19721 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): No INIT-CMDS in
19722 the AC_CONFIG_COMMANDS invocation.
19723 This also solves the name clash problems.
19724 Don't set the package's ID.
19725 * lib/m4sugar/Makefile.am (version.m4): Revamp.
19726 No longer to be shipped.
19727 (version.in): Remove.
19728 * lib/m4sugar/m4sugar.m4, lib/autoconf/general.m4,
19729 * lib/autoconf/status.m4: Adjust.
19730 Use `m4_PACKAGE_STRING'.
19731 * lib/autotest/general.m4 (AT_INIT): N-th signature change: now
19732 the only optional argument is the name of the test suite.
19733 Expect `package.m4' to define the package signature.
19734 * lib/autom4te.in (Autotest): Add `package.m4?'.
19735 * tests/Makefile.am (package.m4): New.
19736 * tests/suite.at: ifnames is a victim.
19738 2001-09-18 Akim Demaille <akim@epita.fr>
19740 * lib/autom4te.in (Autoconf): Preselect AM_CONDITIONAL,
19741 AC_LIBSOURCE, AC_CONFIG_FILES.
19742 * lib/autotest/general.m4 (AT_INIT): Don't abort when a tested
19743 program version string doesn't match the package's.
19744 * lib/autoconf/general.m4 (AC_CACHE_VAL): Reestablish the space

19755 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):
19756 Always include <stdio.h> and <stdlib.h>. Evaluate
19757 the expression in an extra function before these includes. Call
19758 fprintf "%d" only after ensuring the argument is of type 'int'.
19759 Reported by Wayne Chapeskie <waynec@spinnaker.com>.
19761 2001-09-17 Paul Eggert <eggert@twinsun.com>
19763 Fix bug reported by Paul Townsend on AIX 4.3.3.0 with CFLAGS=-O4
19764 or CFLAGS=-O5. In that case, the linker has a relaxed view of
19765 fatal errors, and AC_CHECK_LIB causes it to include libraries even
19766 when they don't exist.
19768 * lib/autoconf/headers.m4 (AC_HEADER_DIRENT): Use AC_SEARCH_LIBS,
19769 not AC_CHECK_LIB, so that we don't use -ldir or -lx if we don't
19772 * lib/autoconf/specific.m4 (AC_ISC_POSIX): Replace the old, crufty
19773 version with the version used by fileutils 4.1, except use
19774 AC_SEARCH_LIBS, not AC_CHECK_LIB, so that we don't use -lcposix if
19777 * doc/autoconf.texi (AC_ISC_POSIX): Describe new behavior.
19779 2001-09-13 Akim Demaille <akim@epita.fr>

19819 * lib/autotest/general.m4 (AT_INIT): Create and remove
19820 `$as_me.[0-9]+' instead of `debug-[0-9]+.sh', so that multiple
19821 test suites can cohabit.
19823 2001-09-13 Akim Demaille <akim@epita.fr>
19825 * tests/mktests.sh: Don't output banners for empty test files.

19877 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Don't pass

19880 * lib/autoconf/programs.m4 (AC_SHELL_PATH_WALK): Use PATH_SEPARATOR.

19931 2001-09-05 Akim Demaille <akim@epita.fr>
19933 Be ready to handle filenames as stupid as `dnl.at', for if even
19934 the maintainer is dumb enough to do that...
19936 * lib/autotest/general.m4 (AT_SETUP, AT_LINE): Demonstrates your
19937 excellence in M4 quotation: consider `__file__' is active.
19939 And BTW, when invoking m4, pass the --include in the right order:
19942 * bin/autom4te.in, bin/autoupdate.in: Use reverse when kingtal to

19970 New, extracted from main.
19971 Use IO::File wherever possible.

20016 to m4sugar was lacking!
20018 2001-08-31 Akim Demaille <akim@epita.fr>
20020 * man/Makefile.am (.x.1): We really have to pass
20021 autom4te_perllibdir.
20023 2001-08-31 Akim Demaille <akim@epita.fr>
20025 * lib/autotest/general.m4 (AT_INIT): Don't pass all the args to

20088 Map --localdir, --autoconf-dir onto it.
20089 Forward autom4te's options instead of interpreting them.

20091 There is no such envvar since the inception of autom4te.cfg.

20119 * tests/atlocal.in: Remove all the obscure envvar manipulations.
20121 * tests/atspecific.m4, tests/tools.at: Passing --localdir is
20122 indeed related to running the test suite, while passing

20124 Autoconf executables. So don't do that, leave it to...

20126 * tests/autoscan: New.
20127 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): Don't

20146 2001-08-29 Akim Demaille <akim@epita.fr>

20173 foo=`(command) 2>/dev/null`

20413 * ChangeLog, ChangeLog.0, ChangeLog.1, ChangeLog.2, AUTHORS, BUGS,
20414 * NEWS, README, README-alpha, TODO, tests/README: This package is
20415 `Autoconf', not `autoconf' (the executable).

20471 * lib/autoconf/general.m4, lib/autoconf/specific.m4,

20616 2001-08-15 Akim Demaille <akim@epita.fr>
20618 * bin/autom4te.in (@m4_warning): New.

20690 2001-08-11 Alexandre Duret-Lutz <duret_g@epita.fr>
20692 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Handle ACTION-IF-TRUE,
20693 ACTION-IF-FALSE, and ACTION-IF-UNKNOWN.
20694 * doc/autoconf.texi (C Compiler Characteristics): Update
20695 documentation for AC_C_BIGENDIAN.
20697 2001-08-11 Alexandre Duret-Lutz <duret_g@epita.fr>

20700 magic values from an object file when cross-compiling.
20701 Based on code by Guido Draheim <Guido.Draheim@gmx.de>.
20703 2001-08-10 Akim Demaille <akim@epita.fr>
20705 * bin/autom4te.in (&handle_output): Don't use `grep' with side
20707 Suggested by Russ Allbery.
20709 2001-08-10 Ralf Corsepius <corsepiu@faw.uni-ulm.de>
20711 * lib/autoconf/general.m4 (_AC_OUTPUT_SUBDIRS): Propagate the
20712 current $prefix to the sub-configures.
20714 2001-08-09 Tim Van Holder <tim.van.holder@pandora.be>
20716 * lib/autoconf/lang.m4: Ignore *.xSYM when looking for an executable
20717 extension (needed on BeOS). Reported by Guido van Rossum.
20719 2001-08-09 Akim Demaille <akim@epita.fr>
20721 * bin/autom4te.in ($icache): Load it only if older than autom4te.
20723 2001-08-07 Akim Demaille <akim@epita.fr>
20725 * lib/autotest/general.m4 (AT_INIT): All the `at-*' are to be
20727 (at-setup-line): Huh? Be a variable `at_setup_line', not a file.
20728 No need to remove the files before and after the each test, before
20729 each test and at the end of the suite is enough.
20730 Display only the children `times', not the shell's.
20731 If the test failed or was skipped, at-times is not available.
20733 2001-08-07 Akim Demaille <akim@epita.fr>
20735 Always produce testsuite.log, including when there are no
20736 failures. This helps getting information on skipped tests, and
20737 duration of the tests. Err, implement the latter btw.
20739 * lib/autotest/general.m4 (AT_INIT): Set up fd 6 for the log.
20740 Dump information on the first run of each test.
20741 (AT_CLEANUP): Create `at-times' containing the duration of the
20744 2001-08-07 Akim Demaille <akim@epita.fr>
20746 The use of `dumpstat' revealed that `len' was used although it
20747 should not. m4_text_wrap was using it, but in the Autoconf world
20748 where it is legal. Hence (i) test M4sh in its own world, not
20749 Autoconf's, and (ii), ahem, fix the bug :)
20751 * lib/autotest/general.m4: Be sure the set good quotes, as tracing
20752 does not like `' instead of [].
20753 (AT_INIT): Forbid `^_?AT_'.
20754 And don't output such tokens.
20755 * tests/Makefile.am (CLEANFILES): Add `script', `script.s4g',
20756 `script.as', and `autom4te.cache'.
20757 Remove `empty' and `macro' which are no longer used.
20758 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): New.
20759 * tests/m4sugar.at: Use it.
20760 * lib/m4sugar/m4sugar.m4: Use `m4_len' not `len'.
20762 2001-08-07 Akim Demaille <akim@epita.fr>
20764 * bin/autoconf.in, bin/autoheader.in: --force, -f is a new option.
20766 2001-08-07 Alexandre Duret-Lutz <duret_g@epita.fr>
20768 * bin/autom4te.in (handle_output): Typo in quadrigraph substitution.
20770 2001-08-04 Akim Demaille <akim@epita.fr>
20772 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA, AC_FUNC_ERROR_AT_LINE)
20773 (AC_FUNC_FSEEKO, AC_FUNC_OBSTACK): Use AC_LANG_IFELSE, not
20775 * lib/autoconf/headers.m4 (AC_HEADER_MAJOR): Likewise.
20776 * lib/autoconf/fortran.m4 (_AC_LANG_PROGRAM_C_F77_HOOKS)
20777 (AC_F77_MAIN): Likewise.
20779 2001-08-04 Akim Demaille <akim@epita.fr>
20781 Don't rely on M4sugar outputting the patterns in files, since we
20782 might process the output _without_ running m4, hence without these
20785 * lib/m4sugar/m4sugar.m4 (m4_init): No need for `m4_tmpdir'.
20786 * bin/autom4te.in (@Request::includes): Remove, unused.
20787 (@Request::source): Rename as...
20788 (@Request::input): this.

20793 (m4_pattern_forbid, m4_pattern_allow): Adjust for tracing only.
20795 2001-08-04 Akim Demaille <akim@epita.fr>
20797 `autoconf && autoheader' is sped up. Now, speed up `autoheader &&
20798 autoconf', i.e., in addition to caching traces, cache the output.
20800 * bin/autom4te.in (Request::cache): Rename as...
20801 (Request::id): this.
20802 ($cache, $icache, $tcache, $ocache): New.
20803 (&handle_m4): Save M4 output in the cache instead of $tmp.

20805 (&up_to_date_p): Check that the output cache is up to date too.
20806 (top level): Run `&handle_m4' iff force or the cache is invalid.

20809 2001-08-04 Akim Demaille <akim@epita.fr>
20811 * bin/autom4te.in ($force): New.
20812 (&parse_args, &print_usage): -f, --force is a new option.
20813 (&handle_output): CPP directives might have spaces after `#'.
20814 (&parse_args): The first file only can be frozen.
20816 2001-08-04 Akim Demaille <akim@epita.fr>
20818 Don't let autom4te compute the `include' traces several times:
20819 first check that the trace cache file is up to date, and then
20820 compare its timestamp with that of the output.
20822 * bin/autom4te.in, bin/autoupdate.in, bin/autoscan.in: Normalize
20823 the preamble. Don't require 5.005 as Autom4te::General does it,
20824 and better yet (use `use', not `require'!).
20825 * lib/Autom4te/Struct.pm: Rename the last occurrences of
20826 Class::Struct as Autom4te::Struct.
20827 * lib/Autom4te/General.pm (File::stat): Use it.
20828 (&mtime): New, export it.
20829 * bin/autom4te.in: Use it.
20830 Declare `$req' is invalid if it is outdated.
20831 Don't declare it valid before saving it if something went wrong.
20833 2001-08-04 Akim Demaille <akim@epita.fr>
20835 Autom4te shall not encode Autoconf data, and preselecting traces
20836 must be proposed to the users.
20838 * bin/autom4te.in (@required_trace): Remove.
20840 (&parse_args, &print_usage): -p, --preselect is a new option.
20841 (&up_to_date_p): Adjust.

20857 * bin/autoconf.in ($@): Work around the usual sh bug.
20860 2001-08-03 Akim Demaille <akim@epita.fr>
20862 Clean up the handling of the M4 builtins tracing exception.
20864 * bin/autom4te.in (Request::request): Don't complete M4 builtins

20868 (%m4_builtin_alternate_name): New.
20869 (&parse_args): Complete the trace requests with alternate names.

20881 (m4_divert_pop): Dump the whole diversion stack when a diversion
20883 * bin/autom4te.in (&handle_output): Remember of the first
20884 occurrence of a possibly undefined macro, not the last.
20885 Complain about the possibly undefined macros in the same order as
20886 the appear in the output.
20887 * lib/autoconf/Makefile.am (autoconf.m4f): List its dependencies.
20888 * tests/tools.at (autoconf: forbidden tokens, basic)
20889 (autoconf: forbidden tokens, exceptions): No longer sort
20890 autoconf's stderr, as it is now deterministic.
20891 Check that `dnl' is caught.

20913 `END', as `Autom4te::General::END' will be triggered.
20914 * bin/autoupdate.in, bin/autoscan.in: Improve error messages accuracy.
20915 * bin/autoupdate.in (File::Compare, File::Copy): Use them instead of
