3 Try to update config.cache atomically; respect symlinks.
4 * lib/autoconf/general.m4 (AC_CACHE_SAVE): Use `mv -f' to update
5 the cache file if it is a regular file and not a symlink. Move
6 first to temporary name in the target directory if not in the
7 current directory for atomicity across mount points.
8 * tests/base.at (AC_CACHE_CHECK): Try symlinked cache file.

63 <${var=literal}>: Tweak wording. Add mention of an ambiguity
65 * tests/torture.at (Substitute and define special characters):

71 m4sh: revert incorrect mix of "${a='b'}"
72 * bin/autoconf.as: Revert leak of literal '' into assignment.

80 * lib/m4sugar/m4sh.m4 (AS_VAR_TEST_SET): Make more compact.
82 tests: improve some shell assumption testing

120 AC_HEADER_STDBOOL: avoid spurious failure with modern xlc
121 * lib/autoconf/headers.m4 (AC_HEADER_STDBOOL): Move the "bool e =
122 &s;" test into the main program, as C99 might plausibly be
123 interpreted as not requiring support for this construction in
124 static initializers. Remove the "#if defined __xlc__" stuff, as
125 the bug is not present in recent xlc implementations, and they
126 reject the test for other (valid) reasons. People using ancient
127 xlc versions, if any, are suggested to update to fixed versions.

142 * lib/autoconf/headers.m4 (AC_HEADER_STDBOOL): Drop gcc (and by
143 extension clang) check in favor of a gnulib test. Force failure,
144 rather than merely testing for a compiler extension.
146 Reported by Anders Kaseorg.
148 2010-08-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

1760 Work around DJGPP shell function return bug with command substitutions.
1761 DJGPP bash 2.04 has a bug in that `return $ac_retval' done in a
1762 shell function which also contains a command substitution causes
1763 the shell to barf. For more details and a fix see:
1764 <http://www.delorie.com/djgpp/mail-archives/browse.cgi?p=djgpp-workers/2009/09/09/03:35:08>

1793 DJGPP fix: remove both conftest and conftest.exe.
1794 The DJGPP compiler may create both `a.out' and `a.exe' without -o,
1795 and both `conftest' and `conftest.exe' with `-o conftest', but not
1796 with `-o conftest.exe'.

1801 * lib/autoconf/general.m4 (AC_SITE_LOAD, AC_CACHE_LOAD): Do not

6660 Cover more potentially problemtic file names. Use the new
6663 Properly handle funny file names for headers in config.status.
6664 The test suite did not cover this bug because the code was not
6665 quoting properly the arguments of `rm -f' (which "fails" silently)
6666 as well as the arguments of `diff' (whose output was redirected to
6667 /dev/null so we couldn't see its error message).

6669 file names passed to `rm' and `diff'.

6782 Add 'testsuite -C dir'.
6783 * lib/autotest/general.m4 (_AT_ARG_OPTION): Move missing argument
6785 (AT_INIT) <PARSE_ARGS_END>: ...here, since -k always takes
6787 <DEFAULTS>: Delay computation of variables based on $at_dir...
6788 <PREPARE_TESTS>: ...to here, since -C can change $at_dir.
6789 <TESTS>: Re-invoke via absolute name, since -C may be in effect.
6790 <PARSE_ARGS>: Parse new option.
6791 <HELP_TUNING>: Document it.
6792 * tests/autotest.at (Choosing where testsuite is run): New test

6807 * doc/autoconf.texi (Particular Programs): Do not mention the
6808 Autoconf version in which the AC_PROG_INSTALL change was done.
6809 Suggested by Paul Eggert.
6811 2008-01-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6813 Fix --help=recursive with multiple AC_CONFIG_SUBDIRS.
6814 * lib/autoconf/general.m4 (_AC_INIT_HELP): If, for recursive help
6815 mode, we change to the source directory, also set $ac_pwd so we
6816 do not go back to the build tree for the next config subdir.
6817 * tests/torture.at (Deep Package): Extend test to contain two
6818 config subdirs on the top level.
6820 Fix parallel `maintainer-check'.
6821 * Makefile.am (maintainer-check-tests): Depend on `all'.
6822 Use `$(MAKE) $(AM_MAKEFLAGS)' instead of plain `make'.
6823 * tests/Makefile.am (maintainer-check-c++, maintainer-check-posix):
6825 (maintainer-check): Serialize the testsuite runs.

6849 2008-01-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6851 * tests/Makefile.am (noinst_SCRIPTS): Renamed from
6852 check_SCRIPTS. Building the wrappers for `all' allows help2man
6853 to use them for the manpages.
6854 Report by Benoit Sigoure.
6856 * bin/autoreconf.in: Discard stderr for $autoconf/$aclocal --help.
6858 2007-12-16 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6860 Fix some write failure cases in Autotest.

6872 (m4_require): Use m4_do, not m4_join.
6874 Fix some whitespace tests on cygwin.

6879 * tests/local.at (AT_CHECK_M4): Cater to new m4 error message.
6881 Optimize AC_REQUIRE.

6884 (m4_require): Avoid extra macro calls.
6886 2007-12-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6888 * tests/torture.at (srcdir): Fix quoting.
6890 Do not pass top_srcdir to configure scripts in testsuite.
6891 * tests/autotest.at (srcdir propagation): Copy install-sh to
6893 (my only test): Drop setting of `top_srcdir'.
6894 * tests/base.at (Input/Output): Likewise.
6895 * tests/local.at (AT_CONFIGURE_AC): Copy install-sh,
6896 config.guess, and config.sub to test source tree.
6897 Drop AC_CONFIG_AUX_DIR setting.
6898 (AT_CHECK_CONFIGURE): Drop setting of `top_srcdir'.
6899 * tests/torture.at (Substitute a 2000-byte string): Drop
6900 AC_CONFIG_AUX_DIR setting, copy install-sh to test source tree.
6901 (Substitute a newline, datarootdir workaround): Likewise.
6902 (Define a newline): Adjust for linenumber changes in configure.ac.
6903 * tests/foreign.at (Libtool): Adjust comment to reflect changes.
6905 * tests/semantics.at (AC_PATH_PROGS_FEATURE_CHECK): Skip test
6906 if `pwd` contains whitespace.
6908 Quote $abs_top_srcdir in tests.

6910 * tests/tools.at (Syntax of the shell scripts): Likewise.
6912 * tests/m4sh.at (LINENO): Quote $0.
6914 Fix testsuite program wrapper for whitespace in `pwd`.
6915 The problem here is that the usual mantra is that command
6916 variables can contain arguments, thus we cannot just escape
6917 $AUTOCONF, $AUTOM4TE etc. The compromise is to put the
6918 $top_builddir/tests directory early in $PATH, so that the
6919 wrappers are found by their plain name.
6920 * tests/wrapper.as: Put $testdir early in $PATH.
6921 (AUTOCONF, AUTOHEADER, AUTOM4TE): Set to plain command names.

6933 <at_func_create_debugging_script, Driver Loop>:
6934 Quote $at_group_dir.
6935 * tests/autotest.at (whitespace in absolute testdir): New test.
6937 * lib/autom4te.in: Quote @datadir@.
6939 Proper file name escaping in Autoconf programs and Perl modules.
6940 This includes escaping of characters special to the shell
6941 as well as special to Perl, e.g., leading `<' or `>'.
6942 For example, when $file starts with `>', `open ">$file"'
6943 wrongly tries to append to a different file.
6944 * bin/autoconf.as: Fix quoting for autom4te options.
6945 * lib/Autom4te/General.pm (shell_quote): New function, taken
6946 from coreutils, written by Jim Meyering.
6948 * bin/autom4te.in (files_to_options, handle_m4): Use shell_quote
6950 * bin/autoreconf.in (parse_args): Likewise.

6954 * bin/ifnames.in: Likewise, XFile usage fixes.
6955 * tests/tools.at (autom4te and whitespace in file names): Extend
6956 test. Test twice, with special characters allowed on w32, and the
6957 rest. Test leading and trailing whitespace, for `open_quote'.
6958 (autotools and whitespace in file names): New, analogous test.
6959 Reported by Paul Eggert and Benoit Sigoure, additional suggestions
6960 by Russ Allbery and Eric Blake.
6963 * lib/Autom4te/Channels.pm, lib/Autom4te/Configure_ac.pm,
6964 lib/Autom4te/Struct.pm, lib/Autom4te/XFile.pm: Likewise.
6965 * lib/Autom4te/FileUtils.pm (open_quote): New function.
6966 (update_file, contents): Use it.
6968 * Makefile.am (autom4te-update): Rewrite for git.
6970 2007-12-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6972 * doc/autoconf.texi (autom4te Invocation, Autom4te Cache): Fix typos.
6974 Fix copyright years.
6975 * Makefile.am, doc/install.texi, lib/autoconf/fortran.m4,
6976 lib/autoconf/lang.m4, lib/freeze.mk: Likewise.
6978 2007-12-04 Eric Blake <ebb9@byu.net>
6980 Manually resync with gnulib, since 'make cvs-update' no longer works.
6981 * build-aux/config.guess: New upstream version.
6982 * build-aux/config.sub: Likewise.
6984 When using older automake, don't downgrade build-aux/texinfo.tex.
6985 * configure.ac (AM_INIT_AUTOMAKE): Add no-texinfo.tex option.
6986 * doc/Makefile.am (TEXINFO_TEX): Add.
6988 2007-11-27 Paul Eggert <eggert@cs.ucla.edu>
6990 Fix AC_C_BIGENDIAN bug caused by new awk method of substitution.
6991 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Don't comment out the
6992 #undef as this runs afoul of our new way of creating config.h.
6993 Problem reported by Jim Meyering in
6994 <http://lists.gnu.org/archive/html/autoconf-patches/2007-11/msg00164.html>.
6996 2007-11-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6998 Fix autom4te for unusual characters in input file names.
6999 * bin/autom4te.in (files_to_options): Quote active characters
7001 * tests/tools.at (autom4te and white space in file names):
7004 * doc/autoconf.texi (Limitations of Usual Tools) <awk>:
7005 Document that Tru64 awk always splits $0.
7007 2007-11-24 Stepan Kasal <kasal@ucw.cz>
7009 * lib/autotest/general.m4 (AT_INIT): Do not extract the
7010 `#AT_STOP_...' line at the end of each test.
7012 2007-11-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7014 * lib/autotest/general.m4 (AT_INIT): For awk line number
7015 extraction script, ensure `$at_group' has a defined value
7016 even for the empty set, and properly quote its usage inside
7019 2007-11-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7021 * doc/autoconf.texi (Shell Functions): New chapter. Document
7022 IRIX sh $0 issue in functions, move content from ...
7023 (Portable Shell): ... here.
7024 (Shell Script Compiler): Note that shell functions are not
7025 totally unportable any more.
7027 2007-11-22 Stepan Kasal <kasal@ucw.cz>
7028 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7030 * lib/autotest/general.m4 (AT_INIT): Exit awk script after
7031 extracting the line numbers of the last needed test.
7033 2007-11-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7035 * lib/autotest/general.m4 (AT_INIT) <at_func_create_debugging_script>:
7038 2007-11-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7040 Fix IRIX testsuite debugging failures: $0 in functions.
7041 * lib/autotest/general.m4 (AT_INIT) <at_func_create_debugging_script>:
7042 Do not use $0 inside a function, as IRIX sh will set that to the
7043 function name rather than the script invocation name.
7045 2007-11-19 Paolo Bonzini <bonzini@gnu.org>
7046 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7048 * lib/autotest/general.m4 (at_func_test): Use cached line numbers
7049 to extract test scripts.
7050 (AT_INIT): Extract and cache test script line numbers.
7052 2007-11-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7054 * lib/autotest/general.m4: Revert 2007-11-15 patch and
7055 subsequent fixups; the awk -> here-document conversion trashes
7056 performance too much with AIX sh.
7058 2007-11-18 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7060 * tests/local.at: Do not test m4, perl with AT_TESTED.
7062 Diagnose and guard against write errors dealing with config.status.
7063 The general idea is this: all write failures from `configure'
7064 writing `config.status' are indicated by $ac_write_error, which
7065 is only checked at the end. This is safe because config.status
7066 code is not executed before the file is complete. Other write
7067 failures, be they inside config.status, or in sub shell/awk
7068 scripts spawned from configure or config.status, typically need
7069 earlier checking, as their results are used right afterwards.
7070 * lib/autoconf/status.m4 (AC_OUTPUT): Initialize `ac_write_fail'
7071 before writing config.status, check afterwards.
7072 (_AC_OUTPUT_FILES_PREPARE, _AC_OUTPUT_FILE)
7073 (_AC_OUTPUT_HEADERS_PREPARE,_AC_OUTPUT_CONFIG_STATUS):
7074 Set `ac_write_error' for write failures to config.status. Barf
7075 upon write failures to temporary files.
7076 Adjust note about closing and reopening the here-document.
7077 (_AC_OUTPUT_HEADER, _AC_OUTPUT_LINK, _AC_OUTPUT_COMMAND)
7078 (_AC_OUTPUT_MAIN_LOOP): Likewise, adjust note about closing and
7079 reopening the here-document.
7080 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
7081 Ensure `ac_write_error' does not escape into config.status.
7082 Also, add a couple of code paths not yet exercised in the test
7083 suite: a config file with input from stdin, and a config header
7085 Suggestion for catching write errors by Bruno Haible.
7087 2007-11-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7089 Avoid error with Tru64 awk and testsuite lines with many words.
7090 * lib/autotest/general.m4 (AT_INIT): In the awk script that
7091 reads the testsuite, set the field separator to an unusual value,
7092 in order to not run over the limit of 199 fields. Tru64 4.0D awk
7093 even splits the input if $i, i>0, was never accessed in the script.
7095 Revert 2007-10-17 change.
7096 * TODO: Multiline args in config files and headers mean something
7097 different and are not fixed, see
7098 <http://lists.gnu.org/archive/html/autoconf-patches/2007-05/msg00017.html>
7099 Report by Stepan Kasal.
7101 * doc/autoconf.texi (Generic Programs): Fix typo.
7103 2007-11-16 Stepan Kasal <kasal@ucw.cz>
7105 AC_*_TOOL does not canonicalize the prefix
7106 * doc/autoconf.texi (Generic Programs): Do not say that
7107 the *_TOOL macros canonicalize, they simply use the `host_alias'.
7109 2007-11-16 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7111 Diagnose write errors in config.status instantiations.
7112 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE)
7113 (_AC_OUTPUT_HEADER, _AC_OUTPUT_MAIN_LOOP): Bail out
7115 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
7116 Extend test to also check for some write error failures, using...
7117 <AT_CHECK_CONFIG_CREATION_NOWRITE>: ...this new macro.
7118 Report by Bruno Haible.
7121 * lib/autotest/general.m4 (AT_INIT) <at_func_log_failure>: Fix
7123 (_AT_CHECK): Use less indentation, to save space.
7125 2007-11-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7127 Add witness macro for @top_build_prefix@ substitution.
7128 * lib/autoconf/status.m4 (_AC_HAVE_TOP_BUILD_PREFIX): New macro.
7129 (_AC_OUTPUT_FILE): Mention it here.
7131 2007-11-15 Paolo Bonzini <bonzini@gnu.org>
7132 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7134 * lib/autotest/general.m4 (at_func_test): Remove.
7135 (AT_INIT): Pre-extract test groups into separate files.
7136 (AT_CLEANUP): Source pre-extracted file instead of calling at_func_test.
7137 Remove at-test-source files together with the $at_group_dir.
7138 * tests/autotest.at (Long test source lines): New test.
7140 2007-11-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7142 Shell functions and variables may share a namespace.
7143 * doc/autoconf.texi (Portable Shell): Mention Solaris sh
7146 2007-11-14 Paul Eggert <eggert@cs.ucla.edu>
7148 * lib/autoconf/types.m4 (_AC_TYPE_LONG_LONG_SNIPPET): Make comment match
7151 2007-11-14 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7153 * lib/autoconf/status.m4: Fix a couple of comment typos.
7155 * lib/m4sugar/m4sh.m4 (AS_TMPDIR): Use $as_me, not $me.
7157 2007-11-13 Jim Meyering <meyering@redhat.com>
7159 Clean up the rule to create "expr".
7160 * tests/Makefile.am (expr): Don't redirect directly to target.
7161 Redirect just once, not for each echo statement.
7162 Use $@, not literal "expr".
7164 2007-11-13 Paul Eggert <eggert@cs.ucla.edu>
7166 Don't worry about preprocessor when testing long long.
7167 See: http://lists.gnu.org/archive/html/bug-gnulib/2007-11/msg00075.html
7168 * doc/autoconf.texi (Preprocessor Arithmetic): New section.
7169 (AC_TYPE_LONG_LONG_INT, AC_TYPE_UNSIGNED_LONG_LONG_INT):
7170 These no longer check for preprocessor flaws.
7171 * lib/autoconf/types.m4 (_AC_TYPE_LONG_LONG_SNIPPET):
7172 Do not check for preprocessor flaws.
7174 2007-11-13 Jim Meyering <meyering@redhat.com>
7176 Adapt dependencies, now that a version change doesn't modify configure.ac
7177 * GNUmakefile: Remove "make clean" kludge.
7178 * lib/m4sugar/Makefile.am (version.m4): Depend on Makefile, not
7180 Don't redirect directly to target.
7181 Use $@, not literal "version.m4".
7183 2007-11-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7185 * doc/autoconf.texi (Making testsuite Scripts): Document
7186 ":;{" shorthand as in previous patch.
7188 2007-11-12 Paul Eggert <eggert@cs.ucla.edu>
7190 * doc/autoconf.texi (Limitations of Builtins): Document problem
7191 with { ... } a bit more clearly. Suggest ":;{" as a shorthand
7193 * lib/m4sugar/Makefile.am (version.m4): Detect 'echo' failure.
7194 Use ":;{" shorthand.
7195 * tests/Makefile.am ($(srcdir)/package.m4): Likewise.
7197 2007-11-12 Jim Meyering <meyering@redhat.com>
7199 Add more non-srcdir build support.
7200 * GNUmakefile (dummy): Split a long line.
7201 Add -v option to autoreconf invocation.
7203 Remove the autoreconf-provided INSTALL, so that we regenerate it.
7204 * GNUmakefile (dummy): Remove INSTALL.
7206 Remove racy commands to build scripts in bin/ and tests/.
7207 * man/Makefile.am (.x.1): Now that scripts in bin/ and tests/
7208 are guaranteed to be built, remove the rules that tried to build
7209 them. Before, with a parallel build, these rules could lead to
7210 two processes writing tests/wrapper.in concurrently.
7212 Build in man/ only *after* building in bin/ and tests/.
7213 * Makefile.am (SUBDIRS): The man-page-creation process runs $(MAKE)
7214 in both bin/ and tests/.
7216 Accommodate non-srcdir build-from-checkout.
7217 * build-aux/git-version-gen: Require an additional parameter: $srcdir.
7218 Use git's --git-dir=$srcdir/.git option.
7219 Add quotes, in case tarball_version_file contains shell meta-characters.
7220 * GNUmakefile (_curr-ver): Pass $(srcdir) to git-version-gen.
7221 * configure.ac: Pass "." to git-version-gen.
7223 Avoid spurious test failures due to version skew.
7224 * GNUmakefile (dummy): Run $(MAKE) clean after autoreconf -i.
7226 2007-11-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7228 Avoid warnings about conftest.dSYM directories on Mac OS X Leopard.
7229 * lib/autoconf/general.m4 (_AC_LINK_IFELSE, _AC_RUN_IFELSE):
7230 Remove conftest.dSYM directory.
7231 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT)
7232 (_AC_LANG_PROGRAM_C_, _AC_FC_MAIN, __AC_FC_NAME_MANGLING):
7233 Remove `conftest.*' recursively.
7234 * lib/autoconf/lang.m4 (AC_LINK_IFELSE): Likewise.
7235 * lib/autoconf/specific.m4 (_AC_SYS_LARGEFILE_MACRO_VALUE):
7237 (_AC_COMPILER_OBJEXT_REJECT): Reject *.dSYM.
7239 Report and analysis by Jeff Squyres and Peter O'Gorman.
7241 2007-11-12 Benoit Sigoure <tsuna@lrde.epita.fr>
7243 Fix typos in variable names.
7244 * tests/semantics.at (test for AC_CHECK_LIB): s/at_m/ac_m/.
7246 2007-11-11 Benoit Sigoure <tsuna@lrde.epita.fr>
7248 Document that $((expression)) is not portable.
7249 * doc/autoconf.texi (Shell Substitutions): Here.
7251 2007-11-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7253 Ignore configure --help* errors due to LINENO-impaired shells.
7254 * tests/torture.at (Configuring subdirectories, Deep Package):
7255 In the --help* tests in read-only trees, make `.' temporarily
7256 writable again for the `stderr' file, and ignore errors due to
7257 the attempt to write configure.lineno.
7258 Report by Patrick Welche.
7260 2007-11-10 Jim Meyering <meyering@redhat.com>
7262 Generate package.m4 in build-dir, not srcdir.
7263 * tests/Makefile.am (package.m4): Adjust target.
7264 Don't redirect directly to $@.
7265 (CLEANFILES): Add package.m4.
7266 ($(TESTSUITE)): Depend on just-built package.m4, not the one
7268 When running $(AUTOTEST), search "." before searching $(srcdir).
7270 Avoid a race condition that would make parallel "distclean" fail.
7271 * tests/Makefile.am (distclean-generic): Replace the default,
7272 automake-provided rule with an identical one, but with an additional
7273 dependency on distclean-local. Simply adding the dependency would
7274 cause automake not to emit the rule at all.
7275 * BUGS: Building with -jN works, now.
7277 Distribute git-version-gen.
7278 * Makefile.am (EXTRA_DIST): Add build-aux/git-version-gen,
7279 since GNUmakefile is distributed, and requires it for dist* rules.
7281 Remove two more generated files from version control.
7282 * INSTALL: Remove generated file.
7283 * lib/autoscan/autoscan.list: Remove generated file.
7285 2007-11-09 Paul Eggert <eggert@cs.ucla.edu>
7287 * GNUmakefile (PATH): Remove stray apostrophes; they become
7288 part of PATH, which isn't wanted here.
7290 2007-11-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7292 New config files output variable `top_build_prefix'.
7293 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Substitute
7295 * doc/autoconf.texi (Preset Output Variables): Document it.
7297 Report by Bob Friesenhahn.
7299 Avoid expr for arithmetic evaluation if the shell accepts $((...)).
7300 * lib/autotest/general.m4 (AT_INIT) <at_func_arith>: New
7301 function, to parametrize arithmetic with expr vs. the shell.
7302 Use it where possible.
7303 Suggestion by Benoit Sigoure.
7305 2007-11-03 Benoit Sigoure <tsuna@lrde.epita.fr>
7307 Adjust the documentation of autotest WRT atlocal.
7308 * doc/autoconf.texi (Making testsuite Scripts): It is not necessary,
7309 when using Automake, to write a rule to produce atlocal, since it's
7310 an AC_CONFIG_FILES. Mention that atlocal.in needs to be
7311 distributed, not atconfig.in.
7313 2007-11-04 Eric Blake <ebb9@byu.net>
7315 Update list information.
7316 * README: Mention new autoconf-commit list.
7317 * doc/autoconf.texi (Introduction): Mention autoconf-commit list.
7319 2007-11-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7321 * lib/autoconf/functions.m4 (_AC_FUNC_MALLOC_IF): Fix comment typo.
7323 * lib/m4sugar/Makefile.am (version.m4): Another bash bug workaround.
7325 * build-aux/.gitignore: Ignore mkinstalldirs.
7327 * doc/autoconf.texi (autoreconf Invocation): Fix an underfull line.
7329 2007-11-03 Jim Meyering <meyering@redhat.com>
7331 s/-/./ in snapshot version string: 2.61a-256-8b556 -> 2.61a.256-8b556
7332 * build-aux/git-version-gen: This syncs from coreutils.
7334 Adjust the build procedure so "make check" works reliably.
7335 * README-hacking: Include an extra step between "make" and
7336 "make check" to ensure that the latter passes.
7338 Use just-built tools, when possible.
7339 * GNUmakefile (PATH): Set and export here, ...
7340 (dummy): ... rather than here.
7342 2007-11-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7343 and Andreas Schwab <schwab@suse.de>
7345 * tests/Makefile.am ($(srcdir)/package.m4): Work around bash
7348 2007-11-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7350 * configure.ac (AC_PREREQ): Require version 2.60, for
7351 AC_PROG_SED, AC_PROG_GREP.
7353 2007-11-02 Benoit Sigoure <tsuna@lrde.epita.fr>
7354 and Jim Meyering <meyering@redhat.com>
7355 and Andreas Schwab <schwab@suse.de>
7356 and Eric Blake <ebb9@byu.net>
7358 Document a bug in GNU Bash with compound commands and redirections.
7359 * doc/autoconf.texi (Limitations of Builtins): Mention that GNU
7360 Bash doesn't properly set $? when `{ ... } >/bad' fails, and give
7363 2007-11-03 Eric Blake <ebb9@byu.net>
7365 Support m4 1.4.5 in testsuite.
7366 * tests/torture.at (Define a newline): Exclude line numbers in
7368 Reported by Ralf Wildenhues.
7370 2007-11-03 Jim Meyering <meyering@redhat.com>
7372 Remove automake-provided files from version control.
7373 * build-aux/elisp-comp: Remove file.
7374 * build-aux/install-sh: Remove file.
7375 * build-aux/missing: Remove file.
7376 * build-aux/mdate-sh: Remove file.
7377 * build-aux/.gitignore: New file.
7378 Suggestion from Ralf Wildenhues.
7380 2007-11-03 Eric Blake <ebb9@byu.net>
7382 Adjust version comparison to account for git snapshot numbers.
7383 * lib/m4sugar/m4sugar.m4 (_m4_version_unletter): Also treat - as a
7384 component separator.
7385 * doc/autoconf.texi (Number processing Macros)
7386 <m4_version_compare>: Document this change.
7387 * tests/m4sugar.at (m4@&t@_version_compare): Test it.
7389 2007-10-30 Bruno Haible <bruno@clisp.org>
7391 * lib/autoconf/types.m4 (_AC_TYPE_LONG_LONG_SNIPPET): New macro,
7392 extracted from AC_TYPE_LONG_LONG_INT and AC_TYPE_UNSIGNED_LONG_LONG_INT.
7393 (AC_TYPE_LONG_LONG_INT, AC_TYPE_UNSIGNED_LONG_LONG_INT): Use it.
7394 Fixes problem with Sun C 5.[0-8] in 32-bit mode, reported in
7395 <http://lists.gnu.org/archive/html/autoconf-patches/2007-10/msg00210.html>
7396 Suggested by Paul Eggert.
7398 2007-10-28 Jim Meyering <meyering@redhat.com>
7400 * README-hacking: Autoconf, Automake, and Perl are required to build.
7401 List Gzip and Tar separately. Suggested by Ralf Wildenhues.
7403 2007-10-28 Jim Meyering <meyering@redhat.com>
7405 README-hacking: Recommend running autoreconf -vi.
7406 * GNUmakefile (dummy): Use autoreconf -i, with appropriate PATH,
7407 so that we use just-built tools when they're available.
7408 Suggestions from Ralf Wildenhues.
7410 2007-10-28 Jim Meyering <meyering@redhat.com>
7412 Make inter-release --version output more useful.
7414 Now, each unofficial build has a version "number" like 2.61a-19-58dd,
7415 which indicates that it is built using the 19th change set
7416 (in _some_ repository) following the "v2.61a" tag, and that 58dd
7417 is a prefix of the commit SHA1.
7418 * build-aux/git-version-gen: New file.
7419 * configure.ac: Run it to set the version.
7420 (AM_INIT_AUTOMAKE): Don't check NEWS here.
7421 * Makefile.am (dist-hook): Arrange so that .version appears only
7422 in distribution tarballs, never in a checked-out repository.
7423 * .gitignore: Add .version here, too. Just in case.
7424 * tests/Makefile.am ($(srcdir)/package.m4): Depend on Makefile,
7425 not configure.ac, now that the version number changes automatically.
7427 Ensure that $(VERSION) is up to date for dist-related targets.
7428 * GNUmakefile: Arrange to rerun autoconf, if the version reported by
7429 git-version-gen doesn't match $(VERSION), but only for dist targets.
7431 2007-10-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7433 Fix `Deep Package' failure with a configure script early in PATH

7435 Report by Jim Meyering.
7437 2007-10-27 Jim Meyering <meyering@redhat.com>
7439 Remove all generated files from version control.
7440 * aclocal.m4: Remove.
7441 * configure: Remove.
7442 * Makefile.in: Remove, along with all other Makefile.in in subdirs.
7443 * .gitignore: Add aclocal.m4, configure and Makefile.in. Sort.
7444 * README-hacking: New file: how to build from just-checked-out sources.
7446 2007-10-23 Eric Blake <ebb9@byu.net>
7448 Improve corner case of m4_expand.
7449 * lib/m4sugar/m4sugar.m4 (m4_expand, _m4_expand): Rewrite more

7452 * doc/autoconf.texi (Evaluation Macros) <m4_expand>: Update
7455 2007-10-23 Paul Eggert <eggert@cs.ucla.edu>

8703 must not be anonymous.

8705 for C++; this drops support for anonymous struct and union types,
8706 which were problematic anyway.

8726 Document the restrictions on AC_CHECK_ALIGNOF's type argument.
8727 * lib/autoconf/types.m4 (_AC_CHECK_TYPE_NEW):
8728 For C, just try sizeof (TYPE) and sizeof ((TYPE)); if the former
8729 works but the latter doesn't, then it's a valid type.
8730 This lets people use function types and so forth.
8731 For C++ there doesn't seem to be a simple solution, so leave it alone.
8732 (AC_CHECK_SIZEOF): Allow argument to be a variable.
8733 (AC_CHECK_SIZEOF, AC_CHECK_ALIGNOF): Don't bother to invoke
8734 AC_CHECK_TYPE; that wasn't documented or necessary.

8941 (_AC_INIT_PARSE_ENABLE2, _AC_ENABLE_IF_ACTION): Adjust.
8943 2007-01-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8945 * doc/autoconf.texi: Fix some typos.
8947 2007-01-05 Paul Eggert <eggert@cs.ucla.edu>
8949 Fix some wording problems noted by Paolo Bonzini in:
8950 http://lists.gnu.org/archive/html/autoconf-patches/2007-01/msg00077.html
8951 * doc/autoconf.texi (Signed Overflow Examples): Give more
8952 discussion about the allow_superuser_privileges example,
8953 and change it a bit to make things clearer.
8954 (Optimization and Wraparound): Clarify whether the compiler
8955 will generate an infinite loop for the example derived from
8956 Autoconf's mktime test.
8957 (Signed Overflow Advice): Say that -ftrapv is meant for debugging.
8958 Also, clarify unsigned multiplication overflow.
8960 2007-01-04 Eric Blake <ebb9@byu.net>
8962 * bin/Makefile.am (RELEASE_YEAR): New macro.
8963 (edit): Use it to supply correct copyright year to scripts.
8964 * bin/autoconf.as (version): Use it.
8965 * bin/autoheader.in ($version): Likewise.
8966 * bin/autom4te.in ($version): Likewise.
8967 * bin/autoreconf.in ($version): Likewise.
8968 * bin/autoscan.in ($version): Likewise.
8969 * bin/autoupdate.in ($version): Likewise.
8970 * bin/ifnames.in ($version): Likewise.
8972 2007-01-02 Paul Eggert <eggert@cs.ucla.edu>
8974 * doc/autoconf.texi (Integer Overflow): Revised based on today's
8975 feedback. The most important changes document what happens when
8976 you convert an out-of-range value to a signed integer type, and
8977 say that (sum < a) != (b < 0) reliably detects overflow when sum =
8980 * doc/autoconf.texi (Integer Overflow): Greatly expand and
8981 rewrite, taking notions from the recent discussion on the gcc and
8982 autoconf mailing lists; please see
8983 http://lists.gnu.org/archive/html/autoconf-patches/2006-12/msg00091.html
8984 and follow the many links.
8985 (Integer Overflow Basics, Signed Overflow Examples):
8986 (Optimization and Wraparound, Signed Overflow Advice):
8987 (Signed Integer Division): New sections.
8989 2006-12-28 Steven G. Johnson <stevenj@alum.mit.edu>
8991 * lib/autoconf/general.m4 (AC_DEFINE_TRACE): Don't include
8992 preprocessor macro arguments in traced name.
8993 * doc/autoconf.texi (Defining symbols): Document longstanding
8994 support for AC_DEFINE-ing macros with arguments, and document
8995 behavior when the same variable has multiple AC_DEFINEs.
8996 * lib/autoconf/fortran.m4 (_AC_FC_WRAPPERS): Revert to the
8997 old implementation which AC_DEFINEs the FC_FUNC and FC_FUNC_
8998 macros directly, giving much shorter and simpler code.
9000 2006-12-28 Malcolm Purvis <malcolmp@xemacs.org> (trivial change)
9002 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Insert a
9003 space before "$ac_configure_args" to prevent a 'config.status
9004 --recheck' failure if ac_configure_args doesn't contain a leading
9005 space. This works around a problem with the XEmacs configure.ac,
9006 which uses the (undocumented) ac_configure_args variable
9007 inconsistently with Autoconf.
9009 2006-12-22 Paul Eggert <eggert@cs.ucla.edu>
9011 * lib/autoconf/functions.m4 (AC_FUNC_MKTIME):
9012 Include <limits.h>, and use its INT_MAX to rewrite the
9013 j loop so that it does not overflow 'int'. Problem reported by
9015 <http://lists.gnu.org/archive/html/bug-gnulib/2006-12/msg00084.html>.
9016 Play it safe by shifting left by 1 rather than multiplying by 2,
9017 as GCC is less likely to optimize this away when the value
9018 is signed (when it assumes overflow leads to undefined behavior).
9019 Also, don't assume time_t uses two's complement.
9021 2006-12-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9023 * tests/torture.at (Substitute a 2000-byte string): Avoid using
9024 a 10kB long (multi-line) string literal, OpenServer 5.0.7 ksh
9025 dumps core on it. Report by Tim Rice.
9027 2006-12-18 Steven G. Johnson <stevenj@alum.mit.edu>
9029 * lib/autoconf/general.m4 (AC_ARG_ENABLE): Print help about
9030 --disable-option-checking to --help output even when
9031 AC_PRESERVE_HELP_ORDER is not used.
9032 (_AC_INIT_PARSE_ENABLE2): Print warnings using actual --enable or
9033 --with argument, rather than argument with [-.] replaced by
9035 * NEWS: Fix typo in previous change; the news was in the
9038 2006-12-18 Paul Eggert <eggert@cs.ucla.edu>
9040 * NEWS: Warnings are now generated by default for unknown
9041 --enable-* and --with-* options.
9042 * doc/autoconf.texi (Option Checking): Renamed from
9043 (Configure Option Checking). Tighten up the wording a bit.
9044 (External Software, Package Options): Cross-reference to Option
9045 Checking, and use this to shorten our section.
9046 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Prefer test -n
9047 "$x" to test "x$foo" != x.
9048 * lib/autoconf/status.m4 (AC_OUTPUT): Likewise.
9049 Don't warn if $enable_option_checking is "no".
9050 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Initialize
9051 ac_unrecognized_opts to the empty string.
9052 Don't echo the unrecognized opts, as this might mishandle
9053 backslashes or leading -.
9054 (AC_PRESERVE_HELP_ORDER): Put the --disable-option-checking
9055 usage next to the other --disable-FEATURE options in the
9058 2006-12-18 Steven G. Johnson <stevenj@alum.mit.edu>
9060 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS, _AC_INIT_PARSE_ARGS):
9061 (_AC_INIT_PARSE_ENABLE2, _AC_INIT_HELP, _AC_ENABLE_IF):
9062 Print warning for unrecognized --with and --enable options
9063 (AC_DISABLE_OPTION_CHECKING): New macro to disable warnings.
9064 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS, _AC_OUTPUT_SUBDIRS):
9065 Disable option checking when subdirs are configured.
9066 (AC_OUTPUT): If warnings are enabled, print warning about
9067 unrecognized --with and --enable options at the end of
9068 the configure output (as well as at the beginning).
9069 * doc/autoconf.texi (Option Checking): New node.
9070 Document new option warning functionality.
9072 2006-12-16 Eric Blake <ebb9@byu.net>
9074 * configure.ac (AC_INIT): Bump version, since 2.61a is released.
9075 * NEWS: Start news for current version.
9077 2006-12-15 Paul Eggert <eggert@cs.ucla.edu>
9079 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT):
9080 Define HAVE_GETMNTENT to 1, not to the empty string.
9081 Problem originally reported by Jochen Friedrich in
9082 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=403243>.
9084 This change prompted by a problem report by Andrey Simonenko in
9085 <http://lists.gnu.org/archive/html/bug-autoconf/2006-12/msg00026.html>.
9086 * doc/autoconf.texi (Defining Symbols): AC_DEFINE works for
9087 object-like macros only, in the traditional portable character
9089 * lib/autoconf/general.m4 (AC_DEFINE_TRACE_LITERAL):
9090 Warn about attempts to define things that are not identifiers.
9091 * lib/autoconf/fortran.m4 (_AC_FC_WRAPPERS): Rewrite to avoid
9092 awful hack that AC_DEFINEd macro names containing parentheses.
9094 2006-12-12 Paul Eggert <eggert@cs.ucla.edu>
9096 * doc/autoconf.texi: Undo some of the 2006-12-10 change. It was
9097 too drastic, even if Texinfo in theory requires it for info mode.
9099 (config.status Invocation): Renamed back from Recreating a
9101 (Obsolete config.status Use): Renamed back from Obsolete Recreation.
9102 (Autoconf 2.13): Renamed back from 20th-century Autoconf 2.
9104 2006-12-11 Paul Eggert <eggert@cs.ucla.edu>
9106 * NEWS: Version 2.61a.
9108 2006-12-11 Paul Eggert <eggert@cs.ucla.edu>
9109 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9111 * NEWS: Document changes with echo and printf, and the lack
9112 of limits on the total size of multi-line values of substituted
9113 variables, and the AC_FUNC_FSEEKO fix.
9115 2006-12-10 Paul Eggert <eggert@cs.ucla.edu>
9117 * doc/autoconf.texi (Writing Autoconf Input): Renamed from
9118 Writing configure.ac.
9119 (Autoconf Input Layout): Renamed from configure.ac Layout.
9120 (Recreating a Configuration): Renamed from config.status Invocation.
9121 (Obsolete Recreation): Renamed from Obsolete config.status Use.
9122 (acconfig Header): Renamed from acconfig.h.
9123 (20th-century Autoconf 2): Renamed from Autoconf 2.13.
9124 (Writing Testsuites): Renamed from Writing testsuite.at.
9125 (Autom4te Cache): Renamed from autom4te.cache.
9127 * BUGS: Remove mention of VPATH problem, since it's now documented
9128 not to be a bug in the Autoconf build procedure itself, but rather
9129 a problem with the proprietary `make' programs.
9131 * doc/autoconf.texi (Build Directories): Add a cross reference
9134 * build-aux/config.guess, build-aux/config.sub, build-aux/texinfo.tex:
9135 * doc/standards.texi: Sync from gnulib.
9137 * man/autoconf.1, man/autoheader.1, man/autom4te.1, man/autoreconf.1:
9138 * man/autoscan.1, man/autoupdate.1, man/config.guess.1:
9139 * man/config.sub.1, man/ifnames.1: Remove from CVS, since they're
9140 generated automatically.
9142 2006-12-06 Paul Eggert <eggert@cs.ucla.edu>
9144 * lib/autoconf/c.m4 (_AC_PROG_CC_C89): Also try -xc99=all, for Sun
9145 C 5.8 on Solaris 10. Using -xc99=all rather than -xc99 bypasses
9146 the buggy -xc99 option of Forte Developer 7 C on Solaris 9.
9148 2006-12-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9150 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Drop the
9151 `CEOF$ac_eof' special marker, the awk script cannot contain a
9152 line matching `^CEOF', so this is not needed any more.
9153 * tests/torture.at (Substitute a newline): Expose the `%!_!# '
9154 special marker in the test.
9156 2006-12-06 Stepan Kasal <kasal@ucw.cz>
9158 * tests/tools.at (autom4te preselections): Use `find -newer';
9159 remove one of the sleeps.
9161 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE): Make it
9162 more readable, using ...
9163 (_AC_INIT_PARSE_ENABLE2): ... this new helper macro.
9165 * doc/autoconf.texi (autoheader Invocation): Do not double-
9166 quote the parameter of `AH_BOTTOM' in the example.
9168 2006-12-05 Stepan Kasal <kasal@ucw.cz>
9170 * doc/autoconf.texi (Configuration Headers): Remove the
9171 example with multiple input files.
9172 (autoheader Invocation): Encourage `AH_BOTTOM', discouraging
9173 multiple input files.
9175 2006-12-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9177 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): When
9178 creating the awk substitution script, handle one input line at a
9179 time, so that the maximum length of a substituted (multi-line)
9180 value is not limited by the size of the sed pattern space.
9181 The trade-off is a slightly repetitive sed script.
9182 * doc/autoconf.texi (Limitations of Usual Tools): Branch labels
9183 can only have up to 7 characters, due to Solaris 10 /bin/sed.
9184 * tests/torture.at (Substitute a 2000-byte string): Increase the
9185 test with several long lines, they should not be caught by sed
9188 * tests/tools.at (autom4te preselections): New test, to flag
9189 entries missing from autom4te.cfg.
9190 Report by David Byron <dbyron@hheld.com>.
9192 * tests/torture.at (Substitute a 2000-byte string): Actually use
9193 AC_PROG_AWK, so the last change works as intended.
9194 (Substitute and define special characters): Likewise.
9195 (Substitute a newline): Likewise.
9197 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Use `$AWK'
9198 instead of `awk' consistently.
9199 (_AC_OUTPUT_CONFIG_STATUS): Initialize $AWK.
9200 * tests/torture.at (Torturing config.status): Test both the
9201 result of AC_PROG_AWK and plain awk.
9202 (Substitute a 2000-byte string): Likewise.
9203 (Substitute and define special characters): Likewise.
9204 (Substitute a newline): Likewise.
9206 2006-12-04 Paul Eggert <eggert@cs.ucla.edu>
9208 * lib/autoconf/functions.m4 (AC_FUNC_FSEEKO): Check that fseeko
9209 can be assigned to a function pointer. Problem reported by
9210 Peter Palfrader in <http://bugs.debian.org/401377>. Based on
9211 part of a patch by Ralf Wildenhues in that same bug report.
9213 2006-12-01 Paul Eggert <eggert@cs.ucla.edu>
9215 * tests/mktests.sh (ac_exclude_list): Exclude AC_FUNC_SETVBUF_REVERSED.
9216 * tests/semantics.at (AC_FUNC_SETVBUF_REVERSED): New test.
9218 2006-12-01 Eric Blake <ebb9@byu.net>
9220 * lib/autoconf/c.m4 (AC_LANG_INT_SAVE): Avoid newline, to aid in
9221 cross-compiling from cygwin to mingw.
9222 Reported by Bob Rossi. This resurrects the 2000-11-30 patch to
9223 aclang.m4, which was mistakenly removed in the 2001-09-17 patch
9224 to lib/autoconf/c.m4.
9226 2006-12-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9228 * lib/m4sugar/m4sh.m4 (_AS_ECHO_PREPARE): Use a longer test
9229 string for more reliable failure. Wrap the entire test that
9230 causes the broken Solaris printf to dump core, in a subshell,
9231 so the segmentation fault message is reliably suppressed.
9232 Fix shell expansion errors by using /usr/ucb/echo always;
9233 avoid an error on systems without it by another subshell.
9234 Avoid m4 expansion of `$1'. Set the zeroth argument of the
9235 subshell-$as_echo to `as_echo', for better error message.
9237 2006-11-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9239 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): If `BASH_ARGV' or
9240 `BASH_SOURCE' contain a newline, set them to empty, as they may
9243 2006-11-27 Paul Eggert <eggert@cs.ucla.edu>
9245 Turn AC_FUNC_SETVBUF_REVERSED into a noop. It's been obsolete for
9246 years and is too hard to maintain now. The last straw was
9247 reported by Jerker Baeck in
9248 <http://lists.gnu.org/archive/html/autoconf/2006-11/msg00102.html>.
9249 * NEWS: AC_FUNC_SETVBUF_REVERSED is now obsolete.
9250 * doc/autoconf.texi (Particular Functions): Move
9251 AC_FUNC_SETVBUF_REVERSED from here...
9252 (Obsolete Macros): ... to here. Say that it does nothing now.
9253 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
9254 Turn into (almost) a no-op.
9256 * lib/autoconf/c.m4 (AC_PROG_GCC_TRADITIONAL, AC_C_CONST):
9258 Do not recommend via AN_FUNCTION, AN_IDENTIFIER, or AN_HEADER.
9259 These macros are obsolescent and new applications shouldn't need them.
9260 * lib/autoconf/functions.m4 (AC_FUNC_CLOSEDIR_VOID, AC_REPLACE_FNMATCH):
9261 (AC_FUNC_GETLOADAVG, AC_FUNC_GETPGRP, AC_FUNC_MEMCMP):

9265 * lib/autoconf/headers.m4 (AC_HEADER_DIRENT, AC_HEADER_STAT):
9266 (AC_HEADER_STDC, AC_HEADER_SYS_WAIT, AC_HEADER_TIME): Likewise.
9267 * lib/autoconf/types.m4 (AC_STRUCT_TM): Likewise.
9269 * doc/autoconf.texi (Setting Output Variables): Mention that
9270 @VAR1@VAR2 has unspecified behavior. Problem reported by
9272 * NEWS: Mention this.
9274 * Makefile.am: Put only a single '#' into the copyright notice,
9275 so that it's also present in the output file. Standardize wording
9276 in makefile copyright notices to match GNU coding standards.
9277 * bin/Makefile.am: Likewise.

9290 2006-11-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9292 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Fix error
9293 in the sed script that mangles the awk script: delete up to the
9294 first exclamation mark only.
9295 * tests/torture.at (Substitute and define special characters):
9298 2006-11-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9300 Rewrite config files generation: avoid quadratic growth in
9301 the number of substituted variables by using awk instead of sed
9302 for the bulk of the substitutions.
9303 * NEWS: Mention this.
9304 * doc/autoconf.texi (Setting Output Variables): `|#_!!_#|' is also
9305 forbidden in the output (and thus input) file.
9306 * lib/autoconf/status.m4 (_AC_AWK_LITERAL_LIMIT): New macro.
9307 (_AC_OUTPUT_FILES_PREPARE): Instead of several sed scripts,
9308 generate just one large awk script for substitutions,
9309 eliminating much of the earlier complexity, while adding some
9310 new complexity. Only expand the substitution templates at
9311 configure time, for smaller configure script size. If
9312 _AC_SUBST_FILES are used, test 'awk' for working getline support
9313 at config.status time. If absent, interpolate through the
9314 shell. The awk script was written with much help
9315 from Paolo Bonzini and Paul Eggert.
9316 (_AC_SED_CMD_NUM, _AC_SED_DELIM_NUM, _AC_SED_FRAG): Removed.
9317 (_AC_SED_FRAG_NUM): Likewise.
9318 (_AC_SUBST_CMDS): Renamed from...
9319 (_AC_SED_CMDS): ...this.
9320 (_AC_OUTPUT_FILE): Use _AC_SUBST_CMDS.
9321 * tests/torture.at (Substitute a 2000-byte string): Also
9322 substitute a line with 1000 words, and a variable with several
9324 (Substitute and define special characters): Test awk special
9325 characters, and put substitution input strings `@foo@' in the
9326 output, to test that no recursion happens; test several other
9327 combinations from Paolo Bonzini.
9329 2006-11-25 Paul Eggert <eggert@cs.ucla.edu>
9331 * lib/autotest/general.m4 (AT_INIT): Undo recent changes
9332 that replaced echo with AS_ECHO where this wasn't necessary.
9333 Problem reportd by Ralf Wildenhues.
9334 * lib/m4sugar/m4sh.m4 (_AS_ECHO_PREPARE): Port to Solaris 7,
9335 where "/usr/bin/printf '%s\n' S" dumps core if S is long.
9336 This is Sun bug 4206210. Problem reportd by Ralf Wildenhues.
9338 2006-11-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9340 * lib/freeze.mk (GREP): Removed, no need to initialize this.
9342 2006-11-21 Paul Eggert <eggert@cs.ucla.edu>
9344 * doc/autoconf.texi (Limitations of Usual Tools): Don't claim
9345 that traditional Awk lacks 3-arg "split". It has it.
9346 Mention that FS must be a single character, and a few other
9347 99-byte limits of traditional Awk.
9348 Mention that if (i in a) doesn't work with traditional Awk.
9350 2006-11-18 Paul Eggert <eggert@cs.ucla.edu>
9352 * tests/autotest.at (BSx641-newline in command):

9354 (Newline-CODE-BS-newline in command):
9355 (Single-quote-BS-newline in command):
9356 (Single-quote-newline-BS-newline in command):
9357 Use printf '%s\n' instead of echo, for portability to hosts
9358 where echo interprets backslashes. This will break on hosts
9359 that lack printf, but for now let's assume all such hosts
9360 are dead (if not, we should get reports of test failures).
9362 2006-11-17 Paul Eggert <eggert@cs.ucla.edu>
9364 'echo' has some portability problems, when given a first argument
9365 with a leading '-', or when given any argument containing '\'.
9366 Avoid using 'echo' in these cases.

9390 (_AS_BASENAME_SED, _AS_DIRNAME_SED, AS_MKDIR_P, AS_TMPDIR, AS_UNAME):
9391 (AS_TR_SH, AS_TR_CPP, AS_VAR_GET): Likewise.
9392 * bin/autoconf.as: Redo verbose flag implementation, as the old
9393 scheme wouldn't work with AS_ECHO.
9394 * lib/autotest/general.m4 (AT_INIT): Likewise.
9395 * lib/autoconf/general.m4 (AC_MSG_RESULT, AC_MSG_RESULT_UNQUOTED):
9396 Don't use ECHO_T, since ECHO_N is now reliable.
9397 * lib/autotest/general.m4 (AT_INIT): Likewise.
9398 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Use sed "$script"
9399 rather than using a here-document to put the script into a file.

9403 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Use
9404 AS_ECHO_N rather than ECHO_N and ECHO_C. This doesn't fix any
9405 bug, but we might as well stop using ECHO_N and ECHO_C internally.

9410 operand, as AS_ECHO requires. Avoid double file name expansion.
9411 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Invoke _AS_ECHO_PREPARE.
9412 Don't set as_nl, since _AS_ECHO_PREPARE does that now.
9413 (_AS_PREPARE): Comment that _AS_ECHO_N_PREPARE is just for user code.
9414 (AS_ECHO, AS_ECHO_N, _AS_ECHO_PREPARE): New macros.

9416 Double-quote strings that would otherwise contain M4 comments.
9417 * tests/m4sh.at (AS_ECHO and AS_ECHO_N): New test.
9419 * configure.ac (AC_INIT): Bump to 2.61a.
9422 2006-11-17 Paul Eggert <eggert@cs.ucla.edu>
9426 * configure.ac (AC_INIT): Bump to 2.61.
9429 * tests/autotest.at (Macro with backslash in a test title):
9430 Comment out for now, as this tests neither fails nor passes
9431 reliably. Problem reported by Ralf Wildenhues.

9435 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE): Fix some typos

9510 benefit of platforms like Solaris+GCC where it is common to have a
9511 non-working g++ installation.

9514 and Joel E. Denny <jdenny@ces.clemson.edu>
9515 and Paul Eggert <eggert@cs.ucla.edu>
9517 * tests/autotest.at (AT_CHECK_AT_TITLE): Fix shell quoting bugs
9518 and non-portable sed scripts, and use $CONFIG_SHELL when invoking
9521 2006-11-08 Paul Eggert <eggert@cs.ucla.edu>
9523 * lib/autoconf/types.m4 (AC_TYPE_LONG_LONG_INT): Set
9524 ac_cv_type_long_long_int to 'yes' instead of 'cross-compiling'.
9525 Imported from a similar patch to gnulib by Bruno Haible.
9527 2006-11-08 Paul Eggert <eggert@cs.ucla.edu>
9529 * NEWS: New macros AC_C_FLEXIBLE_ARRAY_MEMBER, AC_C_VARARRAYS.

9546 and Stepan Kasal <kasal@ucw.cz>
9548 Handle special characters in test case titles correctly.

9551 (AT_SETUP): M4-quote and AS_ESCAPE the title properly everywhere.
9552 * tests/autotest.at (AT_CHECK_AT_TITLE): Add EXPANDED-TITLE-TO-TEST
9553 argument. Extend to check titles printed by ./micro-suite and

9556 Single-quote in a test title,
9557 Double-quote in a test title): Don't expect failure anymore.
9558 (Backslash in a test title): Put a non-whitespace character after the
9559 backslash so that Bourne shells might actually see it as an escape
9561 (Brackets in a test title,
9562 Pound in a test title,
9563 Comma in a test title,
9564 Quoted Macro in a test title,
9565 Macro in a test title,

9567 (Macro with backquote in a test title,
9568 Macro with double-quote in a test title,
9569 Macro with backslash in a test title): New tests expected to fail.
9570 * tests/torture.at (#define header templates): M4-quote this title in
9571 AT_SETUP call so that no M4 code is commented inadvertently somewhere.
9572 The visible effect was a stray [] in the testsuite output.
9574 2006-10-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9576 * doc/autoconf.texi (Limitations of Builtins): Do not invoke
9577 `trap ... 0' inside a function, for AIX sh.
9579 2006-10-26 Paul Eggert <eggert@cs.ucla.edu>
9581 * tests/base.at (AC_COMPUTE_INT): Test **0** rather than 1 / 0,
9582 since powerpc-apple-darwin8-gcc-4.0.1 (Apple Computer, Inc. build
9583 5363) simply issues a warning when dividing by zero at compile
9584 time. Problem reported by Elias Pipping.
9586 2006-10-26 Eric Blake <ebb9@byu.net>
9589 * doc/autoconf.texi (Evaluation Macros): Improve the example to
9590 show effect on macros that expand with commas.

9613 * tools/trace.at (autoconf --trace: user macros): Test `$%'.
9615 2006-10-24 Paul Eggert <eggert@cs.ucla.edu>
9617 * lib/autoconf/specific.m4 (_AC_SYS_LARGEFILE_MACRO_VALUE):
9618 If FUNCTION-BODY is nonempty, use AC_LINK_IFELSE rather than
9619 AC_COMPILE_IFELSE, to work around problem with OSF/1 4.0F fseeko
9620 reported by Nelson H. F. Beebe for Coreutils 6.4.
9622 * tests/tools.at (autoconf --trace: user macros): Remove test
9623 for tracing multiline macros, since m4 1.4.7a uses a different
9624 way to number lines. Problem reported by Ralf Wildenhues.
9626 2006-10-24 Stepan Kasal <kasal@ucw.cz>
9628 * bin/autom4te.in (handle_m4): Do not redirect stdin to
9629 /dev/null since the heuristics for interactive behaviour was

9633 file. Problem reported by Greg Schafer <gschafer@zip.com.au>.

9650 * NEWS: Remove AC_CACHE_CHECK_INT.
9651 * doc/autoconf.texi (Caching Results): Likewise.
9652 * lib/autoconf/general.m4 (_AC_CACHE_CHECK_INT): Renamed from
9653 AC_CACHE_CHECK_INT, since it's no longer public.
9654 * lib/autoconf/types.m4: All uses of AC_CACHE_CHECK_INT changed.
9655 * tests/base.at (AC_COMPUTE_INT): Test this, not AC_CACHE_CHECK_INT.

9683 2006-10-14 Stepan Kasal <kasal@ucw.cz>
9685 * lib/m4sugar/m4sh.m4 (AS_LITERAL_IF): Expand $1 before
9686 looking for special shell characters.
9687 * lib/autoconf/functions.m4 (AC_CHECK_FUNC): Do not expand the
9688 macro defined by AS_VAR_PUSHDEF before passing it as a

9700 2006-10-14 Paul Eggert <eggert@cs.ucla.edu>
9702 (Imported from Automake.)
9703 * build-aux/install-sh (posix_mkdir): Reject FreeBSD 6.1 mkdir -p -m,
9704 which incorrectly sets the mode of an existing destination
9705 directory. In some cases the unpatched install-sh could do the
9706 equivalent of "chmod 777 /" or "chmod 0 /" on a buggy FreeBSD
9707 system. We hope this is rare in practice, but it's clearly worth
9708 fixing. Problem reported by Alex Unleashed in
9709 <http://lists.gnu.org/archive/html/bug-autoconf/2006-10/msg00012.html>.
9710 Also, don't bother to check for -m bugs unless we're using -m;
9711 suggested by Stepan Kasal.
9713 2006-10-14 Paul Eggert <eggert@cs.ucla.edu>
9715 Import this change from Automake:
9717 2006-08-23 Alexandre Duret-Lutz <adl@gnu.org>
9718 * lib/Autom4te/ChannelDefs.pm (usage): Mention that -Wportability
9719 is enabled by default with gnu and gnits strictness.
9720 Report from Bruno Haible.
9722 2006-03-10 Alexandre Duret-Lutz <adl@gnu.org>
9723 * lib/Autom4te/ChannelDefs.pm: Make -Wportability the default in
9724 gnu and gnits modes.
9726 Import this change from Config:
9728 2006-09-20 Ben Elliston <bje@gnu.org>

9731 Import this change from Gnulib:
9733 2006-09-16 Karl Berry <karl@gnu.org>
9734 * doc/fdl.texi (ADDENDUM): switch to @heading from @appendixsubsec,
9735 to avoid sectioning errors.
9737 Import these changes from Texinfo:
9739 2006-10-04 Karl Berry <karl@gnu.org>
9740 * build-aux/texinfo.tex (\singlequotechar): rename to \codequoteright.
9741 (\quoteexpand): rename to \rquoteexpand.
9742 (\codequoteleft): new def, to look for @set codequotebacktick.
9743 (\lquoteexpand, \quoteexpand): new defs.
9744 (\lquoteChar, \rquoteChar, \dashChar, \underChar: new \chardef's.
9745 (\code): must use new \...Char values, since now ` is active.
9747 2006-08-26 Karl Berry <karl@gnu.org>
9748 * build-aux/texinfo.tex (\textdegree): New command.
9750 2006-08-12 Karl Berry <karl@gnu.org>

9755 * doc/autoconf.texi (Autoheader Macros): Fix syntax error.
9757 2006-10-13 Stepan Kasal <kasal@ucw.cz>
9759 * doc/autoconf.texi (Autoheader Macros): Warn that the text
9760 added to the template can get mangled.
9762 2006-10-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9764 * lib/autoconf/functions.m4 (AC_FUNC_OBSTACK): In the test,
9765 include the default headers, and redefine obstack_chunk_alloc
9766 and obstack_chunk_free. Fixes false failure with glibc.
9768 2006-10-12 Paul Eggert <eggert@cs.ucla.edu>
9770 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Set as_executable_p,
9771 for backward compatibility with Libtool 1.5.22. Problem reported
9774 2006-10-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9776 * lib/autoconf/c.m4 (AC_PROG_GCC_TRADITIONAL): Require

9780 2006-10-11 Paul Eggert <eggert@cs.ucla.edu>
9782 * NEWS: AC_USE_SYSTEM_EXTENSIONS now defines _TANDEM_SOURCE for
9783 the NonStop platform.
9784 * doc/autoconf.texi (Posix Variants): Likewise.
9785 * lib/autoconf/specific.m4 (AC_USE_SYSTEM_EXTENSIONS): Likewise.
9787 * lib/m4sugar/m4sh.m4 (AS_TEST_X): New macro.
9788 (AS_EXECUTABLE_P): Use as_test_x rather than as_executable_p.
9789 (_AS_TEST_PREPARE): Set as_test_x rather than as_executable_p.
9790 Use a better substitute, by inspecting the output of "ls"
9791 rather than just using ":".
9792 * lib/autoconf/general.m4 (_AC_LINK_IFELSE): Use AS_TEST_X
9793 rather than AS_EXECUTABLE_P, since we needn't worry about
9794 non-regular files here.
9796 * NEWS: Autoconf-generated shell scripts no longer export BIN_SH,
9797 due to configuration hassles with this. See Tonya Underwood's report
9798 <http://lists.gnu.org/archive/html/bug-autoconf/2006-10/msg00003.html>.

9801 2006-10-11 Paul Eggert <eggert@cs.ucla.edu>
9802 Stepan Kasal <kasal@ucw.cz>
9804 * lib/m4sugar/m4sh.m4 (AS_BOURNE_COMPATIBLE): Don't set BIN_SH.
9805 (_AS_DETECT_BETTER_SHELL): Don't look in /usr/bin/posix.
9807 2006-10-11 Stepan Kasal <kasal@ucw.cz>
9809 * lib/m4sugar/m4sh.m4 (AS_BOURNE_COMPATIBLE): Move the
9810 initialization which is not inherited through the environment
9811 (_AS_BOURNE_COMPATIBLE): ... to this new macro.
9812 (_AS_RUN): Call _AS_BOURNE_COMPATIBLE, not AS_BOURNE_COMPATIBLE.

9817 problems with mkdir -p -m.
9819 2006-10-06 Paul Eggert <eggert@cs.ucla.edu>
9821 * lib/autoconf/c.m4 (_AC_PROG_PREPROC_WORKS_IFELSE): Remove
9822 comment about ac_cpp_err; it was incorrect, and anyway
9823 ac_cpp_err is being removed below.
9824 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE): Don't
9825 set ac_cpp_err to 'yesyes' if preproc_warn_flag and werror_flag
9826 are both 'yes'. In fact, don't bother setting ac_cpp_err at all;
9828 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't log our funky tests
9829 with werror_flag and conftest.err and so forth. This is more
9830 compatible with how _AC_PROG_PREPROC_WORKS_IFELSE behaves,
9831 and anyway the user shouldn't normally want to see this gorp logged.
9832 Problem reported by Ralf Wildenhues.
9833 * lib/autoconf/lang.m4 (AC_LANG_WERROR): werror_flag's default is
9834 empty, not 'no', since the rest of the code uses 'test -z'.
9836 2006-10-04 Paul Eggert <eggert@cs.ucla.edu>
9838 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE):
9839 Use a single call to AC_DO_TOKENS rather than multiple, for
9841 (_AC_LINK_IFELSE): Test that resulting file is executable.
9842 Problem reported by mwoehlke in
9843 <http://lists.gnu.org/archive/html/bug-coreutils/2006-10/msg00048.html>.
9845 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Use "test -x /" rather
9846 than creating a file to use with test -x; this is much faster.
9848 2006-10-02 Bruno Haible <bruno@clisp.org>
9850 * lib/autom4te.in (Automake-preselections): Add
9851 AM_GNU_GETTEXT_INTL_SUBDIR, for automake 1.10.
9853 2006-09-27 Stepan Kasal <kasal@ucw.cz>
9855 * doc/autoconf.texi (Writing testsuite.at): Fix a typo: for

10292 in the restoring of the werror flag.
10294 2006-07-24 Paul Eggert <eggert@cs.ucla.edu>
10296 * doc/autoconf.texi (Volatile Objects): Be even a little
10297 less skeptical about "volatile", after discussion with
10298 Bruno Haible on bug-gnulib.
10299 (Limitations of Usual Tools): Warn about sed stripping
10300 leading white space from text. From Bruno Haible.
10302 2006-07-20 Paul Eggert <eggert@cs.ucla.edu>
10304 * lib/autoconf/libs.m4 (AC_PATH_XTRA): Don't use -R if the
10305 compiler complains about it, even if things works after the
10306 complaint. Problem reported by Peter O'Gorman.
10308 * doc/autoconf.texi (Preset Output Variables): Document CFLAGS,
10309 CPPFLAGS, and LDFLAGS better. Problem reported by Bruno Haible.
10310 Similarly for CXXFLAGS, OBJCFLAGS, ERLCFLAGS.
10312 2006-07-17 Paul Eggert <eggert@cs.ucla.edu>
10314 * lib/autoconf/libs.m4 (AC_PATH_XTRA): Do the check for space
10315 after -R regardless of host. Patrick Welche reports that this
10316 fixes things on NetBSD 3.99.
10318 * NEWS: Recommend M4 1.4.5.
10319 * README: Likewise.
10320 * doc/autoconf.texi (Introduction, Why GNU M4): Likewise.
10321 * tests/tools.at (autom4te cache): Update wording of diagnostic
10324 2006-07-07 Paul Eggert <eggert@cs.ucla.edu>
10326 * doc/autoconf.texi (C Compiler): Add a ref to Volatile Objects
10327 under AC_C_VOLATILE.
10328 (Volatile Objects): Be a little less skeptical about what
10329 "volatile" means. Derived from thoughts by Ben Pfaff in
10330 <http://lists.gnu.org/archive/html/bug-gnulib/2006-07/msg00092.html>.
10332 2006-07-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10334 * doc/autoconf.texi: Fix some typos.
10336 2006-07-07 Paul Eggert <eggert@cs.ucla.edu>
10338 * tests/torture.at (Configuring subdirectories): Set CONFIG_SITE
10339 more globally, since the 2006-06-30 patch didn't suffice. Problem
10340 reported by Keith Marshall. Also, don't bother with builddir2,
10341 since it shouldn't be needed any more.
10343 2006-07-07 Paolo Bonzini <bonzini@gnu.org>
10345 * doc/autoconf.texi (Generic compiler characteristics):
10346 Document AC_COMPUTE_INT. Fix wrong statements on Default
10347 Includes for AC_CHECK_SIZEOF and AC_CHECK_ALIGNOF.
10349 * lib/autoconf/general.m4 (AC_COMPUTE_INT): New.
10350 (_AC_COMPUTE_INT): Add obsoletion warnings.
10351 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF, AC_CHECK_ALIGNOF): Use
10354 * NEWS: Document change.
10356 2006-07-05 Paul Eggert <eggert@cs.ucla.edu>
10358 * doc/autoconf.texi (Volatile Objects): New section.
10360 * NEWS: Document previous change.
10362 2006-07-02 Paul Eggert <eggert@cs.ucla.edu>
10364 * lib/autoconf/types.m4 (AC_TYPE_LONG_LONG_INT):
10365 Require that long long int be at least 64 bits wide. C99 requires
10366 this and enough programs depend on it so we should check for it.
10367 Bruno Haible reports in
10368 <http://lists.gnu.org/archive/html/bug-gnulib/2006-06/msg00286.html>
10369 that long long int is 32 bits wide with some nonstandard compilers.
10370 (AC_TYPE_UNSIGNED_LONG_LONG_INT): Likewise.
10372 2006-06-30 Paul Eggert <eggert@cs.ucla.edu>
10374 * tests/torture.at (Configuring subdirectories): Set CONFIG_SITE
10375 to a nonexistent file, so that we don't have to worry about
10376 a local site configuration that doesn't use /usr/local.
10377 Problem reported by Keith Marshall in
10378 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00133.html>.
10380 2006-06-28 Paul Eggert <eggert@cs.ucla.edu>
10382 * doc/autoconf.texi: Be more consistent about using @acronym with
10383 "HP" and "HP-UX". Remove mention of OSF; the old version wasn't
10384 quite right (it talked about "OSF/Tru64", even though the
10385 operating systems were called OSF/1, Digital UNIX, and Tru64 UNIX,
10386 and it even mentioned "OSF 4"!) and at this point there's little
10387 reason to talk about OSF any more, since it died in 1994.
10388 (Specific Compiler Characteristics): Simplify example of
10389 negative-size array.
10390 (File Descriptors): Reorder to make the text flow better.
10391 Remove joke about "appreciate the various levels"; I didn't get it.
10392 Add remark about HP-UX sh -x bug with stderr noted by Bob Proulx in
10393 <http://lists.gnu.org/archive/html/bug-coreutils/2006-06/msg00225.html>.
10394 (File Descriptors, Limitations of Usual Tools):
10395 Tone down the advice against renaming or removing open files.
10396 (Limitations of Usual Tools): Add a new section, on 'rm'.
10398 2006-06-26 Stepan Kasal <kasal@ucw.cz>
10400 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Use -lX11, not
10401 -lXt in LIBS, idea from Karsten Hopp; this was due since
10404 2005-09-18 Paul Eggert <eggert@cs.ucla.edu>
10405 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Look for X11/Xlib.h
10406 and XrmInitialize rather than X11/Intrinsic.h and XtMalloc
10407 (which belong to Xt, not X itself). See Debian bug 327655.
10409 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10411 * configure.ac (AC_INIT): Bump to 2.60a.
10414 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10418 * configure.ac, NEWS: Update.
10420 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10422 * config/texinfo.tex: Sync from upstream.
10424 * bin/autom4te.in (handle_traces): Transform the `@S|@'
10425 quadrigraph correctly in traces.
10427 * NEWS, lib/Autom4te/C4che.pm, lib/autoconf/functions.m4:
10430 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Expand tests for
10431 datarootdir-related errors only if AC_DATAROOTDIR_CHECKED is
10433 * doc/autoconf.texi (Changed Directory Variables): New node,
10434 to document the whole `datarootdir' business a bit better.
10436 * tests/torture.at (datarootdir workaround): Extend test.
10437 Prompted by report by Alexandre Julliard.
10439 2006-06-22 Paul Eggert <eggert@cs.ucla.edu>
10441 * lib/autoconf/c.m4 (_AC_PROG_CC_C89): Check for C89 incompatibility
10442 when using default mode of IBM C 6 for AIX. Problem and two-line
10443 fix reported by Larry Jones.
10445 2006-06-22 Alexandre Julliard <julliard@winehq.org>
10447 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Avoid warning
10448 about literal '${datarootdir}' if a definition is found in the
10451 2006-06-20 Paul Eggert <eggert@cs.ucla.edu>
10453 * NEWS: Use "M4" rather than "m4" when appropriate.
10454 Problem reported by Eric Blake.
10455 * doc/autoconf.texi: Likewise.
10456 Use @acronym around BSD, GCC, and GNU when appropriate.
10457 (Why GNU M4): Renamed from "Why GNU m4".
10458 (Redefined M4 Macros): Mention that Posix
10459 m4wrap takes only 1 argument, but GNU M4 1.4.x takes more.
10460 (Buffer Overruns): Mention size_t and ptrdiff_t as alternatives
10463 2006-06-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10465 * bin/autom4te.in (handle_output): Do not forbid the empty
10467 * tests/tools.at (autoconf: the empty token): New test.
10469 2006-06-20 Stepan Kasal <kasal@ucw.cz>
10471 * lib/m4sugar/m4sugar.m4 (m4_init): Merge the two m4_wrap
10472 calls, so that we do not care whether they are LIFO or FIFO;
10473 in the m4_wrap, do not check which diversion is the topmost
10474 one, just check that the stack is balanced at the end.
10475 * lib/m4sugar/m4sh.m4 (AS_INIT): We are going to change the
10476 base diversion forever--pop the previous diversion before
10477 opening the new one; consequently, remove the m4_wrap call.
10478 * lib/autotest/general.m4 (AT_INIT): Likewise.
10479 * tests/m4sugar.at: Do not use
10480 m4_wrap([m4_diversion_pop([..])]), for educational purposes.
10482 2006-06-19 Paul Eggert <eggert@cs.ucla.edu>
10483 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10485 * NEWS: Document that m4wrap/m4_wrap might not be LIFO.
10486 * doc/autoconf.texi (Redefined M4 Macros): Likewise.
10487 Rework example of m4wrap token-pasting trouble so that it doesn't
10488 care whether it's LIFO or FIFO.
10489 Fix some "contrary to"s that are awkward in English.
10491 2006-06-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10493 * lib/autoconf/types.m4 (_AC_TYPE_INT): Set `$ac_cv_c_int$1_t'
10494 to `yes' instead of `int$1_t' if the type is found, for more
10495 consistent configure output (where $1 is the number of bits).
10496 (_AC_TYPE_UINT): Likewise for `uint$1_t'.
10497 Suggested by Bruno Haible.
10499 * lib/autoconf/types.m4 (_AC_TYPE_UNSIGNED_INT): Solaris 2.5.1
10500 needs _UINT8_T and _UINT64_T defines as well, to avoid clashes
10501 with system headers. Report by Bruno Haible.
10503 2006-06-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10505 * config/config.guess, config/config.sub: Sync from upstream.
10507 * bin/Makefile.am (autoconf.in): Use `--melt' for autom4te,
10508 in order to avoid picking up an older installed frozen m4sh.m4f.
10509 Besides an outdated shell startup, this could have been created
10510 by an earlier M4 version with incompatible frozen file format.
10512 2006-06-16 Paul Eggert <eggert@cs.ucla.edu>
10514 * README: Recommend m4 1.4.4 instead of 1.4.3..
10515 * doc/autoconf.texi: Likewise.
10516 (Special Chars in Names): Say that $(.FOO) is portable, as
10517 suggested by Stepan Kasal.
10518 (Installation Directory Variables, Build Directories):
10519 (Automatic Remaking, Subdirectories, Fortran Compiler):
10520 (Making testsuite Scripts, Defining Directories):
10521 Quote variable usages better.
10522 (Making testsuite Scripts): Add clean-local rule to makefile
10523 snippet, by Eric Blake.
10524 (Installation Directory Variables): Fix table item font.
10525 Reword slightly to clarify. Generalize advice about
10526 not using special characters to include all file-related
10527 vars, not just VPATH.
10528 (Special Chars in Variables): Warn about special characters in
10530 (Assignments): Clarify default-value example as suggested by
10532 <http://lists.gnu.org/archive/html/autoconf-patches/2006-06/msg00072.html>.
10533 (Special Shell Variables): Note leading ./ or ../, as suggested
10535 (Limitations of Builtins): Under cd, warn about CDPATH.
10536 (The Make Macro MAKEFLAGS): Untabify. Problem reported by
10539 2006-06-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10541 * doc/autoconf.texi (Configuration Actions): Remove duplicate
10542 `@var', for texi2html.
10543 (Systemology): Some more word wrapping, for DVI output.
10544 (autom4te Invocation): The short option for `--melt' is `-M',
10547 2006-06-15 Paul Eggert <eggert@cs.ucla.edu>
10549 * doc/autoconf.texi: More formatting and English tweaks,
10550 many suggested by Ralf Wildenhues.
10551 Reword to avoid "@code{...}'s" and the like, since it's ugly
10552 with Emacs info mode. discontents -> woes.
10553 Put a few "will"s back. time stamp -> timestamp.
10554 side-effect -> side effect.
10556 2006-06-14 Paul Eggert <eggert@cs.ucla.edu>
10558 * doc/autoconf.texi (Initializing configure, Shell Substitutions):
10559 Warn about $@ not persisting. Problem reported by Julien Danjou in
10560 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=372179>.
10561 (Special Chars in Names): Renamed from Leading _ in Macro Names.
10562 Mention other special chars, too.
10564 2006-06-14 Eric Blake <ebb9@byu.net>
10566 * doc/autoconf.texi (The Make Macro MAKEFLAGS): New node.
10568 2006-06-13 Paul Eggert <eggert@cs.ucla.edu>
10570 * doc/autoconf.texi: Some systematic minor improvements, as
10571 follows. Use "makefile" when talking about makefiles
10572 generally (which might be named "makefile" or "Makefile" or even
10573 "foo.mk"), "Makefile" when talking about a specific makefile
10574 called "Makefile". This unclutters the text from weird quotes
10575 (e.g., "`Makefile's" in info mode). Similarly, use "@var{foo}
10576 values" rather than "@var{foo}s" and similar constructs containing
10577 "}s". Use "Make rules" rather than "Makefile rules". Minor
10578 English-language improvements. Change the prefix "sub-" to "sub"
10580 Put blank lines around examples more consistently.
10581 Avoid "rather" and "very" as intensifiers.
10582 Avoid "will" as an auxiliary.
10583 (Limitations of Make): Split this node into....
10584 (Portable Make, $< in Ordinary Make Rules, Failure in Make Rules):
10585 (Leading _ in Macro Names, Backslash-Newline-Newline):
10586 (Backslash-Newline Comments, Long Lines in Makefiles):
10587 (Macros and Submakes, The Make Macro SHELL, Comments in Make Rules):
10588 (obj/ and Make, make -k Status, VPATH and Make):
10589 (VPATH and Double-colon, $< in Explicit Rules):
10590 (Automatic Rule Rewriting, OSF/Tru64 Directory Magic):
10591 (Make Target Lookup, Single Suffix Rules, Timestamps and Make):
10592 New nodes, resulting from splitup of Limitations of Make.
10593 All cross-references changed. Raise the top node from
10594 a section to a chapter, and all subnodes accordingly.
10595 Redo the introductory wording to match the new organization.
10596 (Installation Directory Variables): Use an example that is
10597 closer to what Autoconf actually does. Mention that VPATH's
10598 value should not contain metacharacters or white space.
10599 (Fortran Compiler): Fix a VPATH bug in an example.
10600 (Leading _ in Macro Names): Mention that this problem is no longer
10601 of practical concern.
10602 (VPATH and Make): Reword the advice to make it clearer
10603 that Autoconf and Automake support VPATH in non-GNU make, but
10604 many packages have bugs in this area.
10605 ($< in Explicit Rules): Refer to Build Directories rather
10606 than using a (non-VPATH-safe) example.
10607 (Automatic Rule Rewriting): Mention the sort of disaster that
10608 can ensue with Solaris-style rule rewriting with VPATH.
10610 2006-06-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10612 * doc/install.texi (Compilers and Options): Weaken the
10613 suggestion to use GNU make for VPATH builds.
10615 * lib/autom4te.in (Automake-preselections): Add AM_PROG_CXX_C_O,
10616 AM_PROG_F77_C_O, AM_PROG_FC_C_O, AC_FC_SRCEXT, AC_FC_FREEFORM.
10618 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Fix M4 quotation
10619 in regular expression.
10621 2006-06-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10623 * doc/autoconf.texi (Installation Directory Variables):
10624 Drop extra @samp from `@table @samp' item.
10625 (Limitations of Usual Tools): Comment fix.
10626 Do not nest @samp just to point to other table items.
10627 (Writing testsuite.at) <AT_CHECK>: The second argument to
10628 `@dvar' is already @samp'ed.
10629 (Making testsuite Scripts) <AC_CONFIG_TESTDIR>: Likewise,
10630 do not use @var in the second argument.
10632 2006-06-07 Paul Eggert <eggert@cs.ucla.edu>
10634 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Look for
10635 $as_shell.exe too. Problem reported by Andreas Buening in
10636 <http://lists.gnu.org/archive/html/autoconf/2006-06/msg00038.html>.
10638 2006-06-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10640 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA): Work around
10641 `unused variable' compiler warning, for `-Wall -Werror'.
10642 Reported by Jaap Haitsma in
10643 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00012.html>.
10645 2006-06-06 Paul Eggert <eggert@cs.ucla.edu>
10647 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Remove core file, in
10648 case the compiler dumps core. Problem reported for
10649 OpenServer 5.0.7 by Tim Rice in
10650 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00019.html>.
10651 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE):
10654 2006-06-06 Tim Rice <tim@multitalents.net>.
10656 * lib/freeze.mk: Quiet check-forbidden-patterns so the string
10657 "ERROR" only shows up in "make check" output if there is an

10662 * tests/tools.at (automatically allowed tokens): Fix typo.
10664 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
10666 * NEWS: Don't blame non-GNU VPATH compatibility issues on Automake.
10668 * doc/autoconf.texi (Integer Overflow): Mention that INT_MIN % -1
10669 typically overflows on x86 CPUs, even though the C standard
10670 requires otherwise.
10672 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10674 * configure.ac (AC_INIT): Bump to 2.59e.
10677 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10681 * config/texinfo.tex: Sync from upstream.
10683 * bin/autoreconf.in: Trace `LT_CONFIG_LTDL_DIR'; if it has been
10684 seen, invoke libtoolize with `--ltdl' argument.
10685 * lib/autom4te.in (Autoreconf-preselections): Adjust.
10687 Suggested by Eric Blake.
10689 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>

10711 (AT_CHECK_AUTOM4TE): ... which is now a thin wrapper around
10713 (AT_CHECK_AUTOCONF): Use AT_CHECK_M4; no longer support
10714 `expout' as the last parameter.
10715 * tests/tools.at: Adapt to the above change.
10717 2006-06-04 Stepan Kasal <kasal@ucw.cz>
10719 * doc/autoconf.texi (Limitations of Usual Tools): Correct
10720 information about race-free implementations of mkdir.

10732 Mention that some macros are now documented to be obsolescent.
10733 * doc/autoconf.texi:
10734 Prefer "current" to "modern" to describe
10735 currently-used (albeit perhaps old-fashioned) hosts.
10736 Mention which ancient features no longer need to be worried about.
10737 setgid -> set-group-ID
10738 setuid -> set-user-ID (these are the Posix terms)
10739 Fix some misuses of "only".

10752 Mention that it's now safe to use 3 and 4.
10753 (Limitations of Usual Tools): cp -r is now specified by Posix.
10754 Omit longwinded and obsolescent discussion of cp -f.
10755 Modernize discussion of expr, ls.
10756 (Limitations of Make): Modernize discussion of VPATH builds.
10757 Mention $? as a workaround in some cases.
10758 * doc/install.texi (Basic Installation):
10759 Mention "./configure; make; make install" first. Be more
10760 specific about why this file is generic. Remove unnecessary
10761 parens. Remove misleading "only". Remove obsolete advice
10762 about csh. Don't say "configure" takes awhile; say it
10763 might take a while. Suggest CFLAGS=-g rather than CFLAGS=-O2,
10764 and CC=c99 rather than CC=c89, as these are blessed by current
10765 Posix. Recommend GNU make if doing a VPATH build.
10767 2006-06-03 Paul Eggert <eggert@cs.ucla.edu>
10769 * doc/autoconf.texi: Use a consistent style "$ @kbd{...}" for
10770 examples involving shell prompts.
10772 2006-06-02 Stepan Kasal <kasal@ucw.cz>
10773 and Paul Eggert <eggert@cs.ucla.edu>
10775 * doc/autoconf.texi (Here-Documents): Add details about the
10776 pre-ksh93g bug. Reword slightly to make it clearer. Consistently
10777 use "here-documents" instead of "here documents".
10779 2006-06-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10781 * config/texinfo.tex, doc/standards.texi: Sync from upstream.
10783 2006-06-01 Paul Eggert <eggert@cs.ucla.edu>
10785 * doc/autoconf.texi (File System Conventions): Warn about ":"
10786 anywhere in directory names.
10788 2006-05-31 Paul Eggert <eggert@cs.ucla.edu>
10790 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be even more conservative
10791 about quoting the case statement, just in case.
10792 * doc/autoconf.texi (Here-Documents): Mention that the ksh bug
10793 was fixed in ksh93g; reported by Ralf Wildenhues.
10795 2006-05-31 Stepan Kasal <kasal@ucw.cz>
10797 * doc/autoconf.texi (System Services): Do not document
10798 overriding EXEEXT via ac_cv_exeext=ext.
10799 (Particular Programs) <AC_PROG_MKDIR_P>:
10800 Document that ${MKDIR_P} understands --.
10801 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Improve the
10804 2006-05-31 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10806 * lib/m4sugar/m4sh.m4 (_AS_DIRNAME_PREPARE): Guard against test
10807 argument with leading hyphen. Problem reported by Paul Eggert.
10809 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
10811 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be more conservative
10812 about quoting ac_try: quote all of it, if any of it seems suspicious.
10813 This means we don't have to worry about ${ or sed any more.
10814 Also, double-quote the case statement, to work around misuses via
10815 underquoting as reported by Ralf Wildenhues in
10816 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00169.html>.
10817 (_AC_EVAL_STDERR): Revert, since evidently some packages rely on this
10818 undocumented and dangerous macro.
10819 Problem reported by Ralf Wildenhues in
10820 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00168.html>.
10822 2006-05-31 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10824 * lib/m4sugar/m4sh.m4 (_AS_DIRNAME_PREPARE): Check whether
10825 `dirname -- /' returns `/', for SunOS dirname scripts that escaped.
10826 Report by Sam Sirlin <sam@kalessin.jpl.nasa.gov>.
10828 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
10830 * lib/autoconf/general.m4: Revert AC_TRY_EVAL and AC_TRY_COMMAND,
10831 since evidently some packages rely on the old, broken behavior.
10832 Problem reported by Ralf Wildenhues in
10833 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00160.html>.
10834 (AC_TRY_EVAL, AC_TRY_COMMAND, _AC_EVAL): Go back to the
10835 pre-2006-05-26 definitions, but leave in the comments that
10836 these macros are dangerous and should not be used.
10837 (_AC_DO_ECHO): Renamed from _AC_EVAL_ECHO. All callers changed.
10838 (_AC_DO): Renamed from _AC_EVAL. All callers changed.
10839 (_AC_DO_STDERR): Renamed from _AC_EVAL_STDERR. All callers changed.
10840 (_AC_DO_VAR): Renamed from AC_TRY_EVAL.
10841 (_AC_DO_TOKENS): Renamed from AC_TRY_COMMAND.
10843 2006-05-29 Paul Eggert <eggert@cs.ucla.edu>
10845 * lib/autoconf/status.m4 (AC_OUTPUT_MAKE_DEFS): Rewrite to avoid
10846 the use of 'tr', since this is our only use of 'tr'.
10848 2006-05-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10849 and Paul Eggert <eggert@cs.ucla.edu>
10851 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE):
10852 Don't assume 'grep' works on long lines, since AIX grep doesn't.
10854 2005-05-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10856 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Do not use `grep' on
10857 the output file in the `${datarootdir}' test.
10859 2005-05-28 Stepan Kasal <kasal@ucw.cz>
10860 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10862 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If we have not seen
10863 mention of `datarootdir' in the input file(s), but literal
10864 `${datarootdir}' in the output file, and we haven't warned yet,
10865 then warn as well: the user may have (erroneously) used
10866 `AC_SUBST([mydatadir], [$datadir/my])' instead of the correct
10867 `AC_SUBST([mydatadir], ['${datadir}/my'])'.
10868 * tests/torture.at (datarootdir workaround): Extend this test.
10871 2006-05-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10872 and Paul Eggert <eggert@cs.ucla.edu>
10874 * doc/autoconf.texi (autoheader Invocation): The first argument to
10875 `AC_DEFINE_UNQUOTED' need not be a literal. Mention the
10876 alternatives and clear up the language a bit.
10878 2006-05-27 Paul Eggert <eggert@cs.ucla.edu>
10880 * NEWS: Reword notice for AC_TRY_COMMAND, AC_TRY_EVAL,
10881 ac_config_guess, ac_config_sub, ac_configure.
10882 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
10883 Fix typo that prevented an unnecessary space from being removed.
10884 Problems reported by Ralf Wildenhues in:
10885 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00143.html
10887 2006-05-26 Paul Eggert <eggert@cs.ucla.edu>
10889 * doc/autoconf.texi (Particular Programs, Limitations of Usual Tools):
10890 Use better wording to talk about AC_PROG_MKDIR_P's thread-safety.
10891 Don't use the term "thread-safe" to talk about mkdir race
10892 conditions, since the problem is more a process than a thread
10893 issue. Problem reported by Stepan Kasal in:
10894 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00088.html
10895 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Use code that mimics
10896 the test for 'install' more closely. Look at MKDIR_P first.
10897 Look in the PATH, and at /opt/sfw/bin.
10898 Look for a 'gmkdir' program as well (Solaris 10 /opt/sfw/bin/gmkdir).
10899 Don't bother to try mkdir -p, since we already check mkdir --version;
10900 just look at the version number. (There's no easy way to check
10901 for race-free implementations.)
10902 * tests/tools.at (autoconf: subdirectories): Adjust to above
10903 changes, since MKDIR_P now might end in "/mkdir -p".
10905 * doc/autoconf.texi (autoheader Invocation): Mention that the
10906 first arg of AC_DEFINE_UNQUOTED must be a literal.
10907 Problem reported by Ben Pfaff in
10908 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00090.html>.
10910 * NEWS: Mention that AC_TRY_COMMAND and AC_TRY_EVAL may be removed.
10911 * doc/autoconf.texi (Special Chars in Variables): New section.
10912 (Preset Output Variables): Warn about special chars in CPPFLAGS.
10913 (Installation Directory Variables): Quote $(datadir) better.
10914 (Limitations of Builtins): Describe some of eval's trickiness.
10916 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Simplify quoting.
10917 * lib/autoconf/fortram.m4 (_AC_PROG_FC_V_OUTPUT): Likewise.
10918 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Put leading space
10919 in front of every arg, not just trailing args. Quote apostrophes.
10920 (_AC_EVAL_ECHO): New macro.
10921 (_AC_EVAL, AC_EVAL_STDERR): Use it. Quote arg of eval.
10922 (AC_TRY_EVAL, AC_TRY_COMMAND): Mention that these macros might get
10924 (_AC_LINK_IFELSE): Use proper rule for shell continuation lines,
10925 exposed by quoting of eval argument. Put the command on line line
10927 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): Use eval more safely.
10928 (_AC_PATH_X, AC_PATH_X): Quote more safely.
10929 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Use eval more safely.
10930 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Don't use eval.
10931 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Minor style change.
10932 Handle special chars in prefix, ac_srcdir, ac_aux_dir.
10933 Use eval more safely.
10934 (_AC_OUTPUT_CONFIG_STATUS): Adjust to above changes.
10935 * lib/m4sugar/m4sh.m4 (AS_VAR_GET): Note that this API needs
10937 * tests/base.at (AC_TRY_COMMAND): Use proper rule for shell continuation
10938 lines, exposed by quoting of eval argument.
10940 2006-05-26 Stepan Kasal <kasal@ucw.cz>
10941 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10943 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Drop the
10944 initialization of `ac_cv_exeext', do not override it if it was
10945 already set, unless it was set to `no', for compatibility with
10946 Autoconf-2.13, and comment this.
10947 Do not export `ac_cv_exeext', Libtool hasn't needed this for years.
10948 (_AC_COMPILER_EXEEXT_DEFAULT): Likewise, do not export it.
10949 (_AC_COMPILER_EXEEXT_WORKS, _AC_COMPILER_EXEEXT_CROSS): Typos.
10950 * doc/autoconf.texi (Compilers and Preprocessors) <EXEEXT>:
10951 Document that this test may be overridden by setting
10954 2006-05-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10956 Revert these two patches:
10958 2006-04-06 Eric Blake <ebb9@byu.net>
10959 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_O): Inside cache
10960 check, s/ac_exeext/ac_cv_exeext/. Fixes regression introduced
10963 2006-04-01 Stepan Kasal <kasal@ucw.cz>
10964 Clean up _AC_COMPILER_EXEEXT* macros.
10965 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't try to
10966 detect exeext, it will be done by _AC_COMPILER_EXEEXT_O; just set
10967 ac_file to the name of the default output file and call
10968 _AC_COMPILER_EXEEXT_WORKS. Move the definition of ac_files and the
10969 initial `rm' of the candidate files...
10970 (_AC_COMPILER_EXEEXT): ... here and simplify them. Moreover, use
10971 the same list in subsequent `rm' calls, and for the temporary
10972 redefinition of ac_clean_files; call _AC_COMPILER_OBJEXT at the end,
10973 and don't call the other _AC_COMPILER_EXEEXT_* macros directly, use...
10974 (_AC_COMPILER_EXEEXT_TESTS): ... this new macro.
10975 (_AC_COMPILER_EXEEXT_O): Don't export ac_cv_exeext, it's not needed (or
10976 no longer needed) by libtool. Make it a cache check.
10977 (_AC_COMPILER_EXEEXT_CROSS): Remove the comment, it was obviously
10978 copied here by mistake.
10979 (AC_NO_EXECUTABLES): Redefine _AC_COMPILER_EXEEXT_TESTS, not
10980 _AC_COMPILER_EXEEXT.
10981 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX, AC_PROG_OBJC): Do not call
10982 _AC_COMPILER_OBJEXT directly.
10983 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
10985 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10987 * doc/autoconf.texi (Limitations of Usual Tools) < sed (`t')>:
10988 Fix description of how the buggy `sed' works.
10990 2006-05-25 Noah Misch <noah@cs.caltech.edu>
10992 Sync from Automake:
10994 * lib/Autom4te/XFile.pm (lock): Allow EOPNOTSUPP, besides
10995 ENOLCK. Only mention `make -j' when applicable. Only raise
10996 fatal errors when `make -j' is involved. Improve error message.
10998 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11000 * doc/autoconf.texi (Here-Documents): We now know more about
11001 the variable expansion in here documents bug.
11002 Thanks to Tim Rice and Stepan Kasal.
11004 * doc/autoconf.texi (Making testsuite Scripts): Add an example
11005 how to use TESTSUITEFLAGS. Suggested by Eric Blake.
11007 2006-05-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11009 * tests/autotest.at (Multiline command from M4 expansion):
11010 No failure to be expected if the shell quotes newlines in
11011 commands in the `set -x' output. Report by Tim Rice.
11014 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
11016 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Don't use shell
11017 expansion in the here-documents used by config.status, as that
11018 runs afoul of the Korn shell version M-12/28/93d bug described in
11019 the Autoconf manual, and this in turn causes a Coreutils 5.95 build to
11020 fail as described by Tim Rice and diagnosed by Ralf Wildenhues in
11021 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00082.html>.
11023 2006-05-23 Jim Meyering <jim@meyering.net>
11025 * lib/autoconf/functions.m4 (AC_FUNC_LSTAT_FOLLOWS_SLASHED_SYMLINK):
11026 Fix typo introduced with 2006-04-02 change. It reversed the sense
11029 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
11031 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Simplify ac_dA and
11032 ac_dB slightly, to save bytes in the script.
11033 Max out at 50 lines, rather than 96; this is more likely
11034 (though not guaranteed) to avoid obscure 'sed' failures.
11036 2006-05-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11038 * lib/autotest/general.m4 (AT_INIT): UnixWare `tr' may interpret
11039 `tr -d -' as bad option argument. Work around this by deleting
11040 an unrelated character.
11041 Report by Tim Rice <tim@multitalents.net>.
11043 2006-05-22 Paul Eggert <eggert@cs.ucla.edu>,
11044 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
11045 Stepan Kasal <kasal@ucw.cz>
11047 * doc/autoconf.texi (Particular Programs): Do not promise that
11048 we always prefer the GNU version of the program, and that we
11049 search according to PATH; both rules can have exceptions.
11050 Update description of AC_PROG_GREP, AC_PROG_EGREP, AC_PROG_FGREP,
11051 AC_PROG_SED. Move descriptions of limitations
11052 to the Limitations of Usual Tools section.
11053 (Limitations of Usual Tools) <sed>: Mention script length
11054 limitations with Solaris /usr/ucb/sed.
11055 <grep>: Fix wording for empty alternative. Mention that -c and
11056 -l should not be combined, and that -E and -F should not be
11059 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
11060 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11062 * lib/autoconf/programs.m4 (AC_PROG_SED): Catch script length
11063 limits in Solaris 8 /usr/ucb/sed by testing a long script.
11065 2006-05-22 Stepan Kasal <kasal@ucw.cz>
11067 * doc/autoconf.texi (Defining Symbols): Literal parameter of
11068 AC_DEFINE is now passed to m4_pattern_allow.
11069 * NEWS: Mention that; likewise for AC_SUBST.
11070 * lib/autoconf/general.m4 (AC_DEFINE_TRACE_LITERAL): Pass
11071 the parameter to m4_pattern_allow.
11072 * tests/tools.at: Add a check for that.
11074 2006-05-22 Stepan Kasal <kasal@ucw.cz>
11076 * lib/autoconf/status.m4: Fix typos.
11078 2006-05-21 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11080 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Remove
11081 only the files that this macro generates.
11083 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
11085 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: For
11086 the HP-UX sed limitation of 99 commands, labels do not count.
11087 * lib/autoconf/status.m4 (_AC_SED_CMD_LIMIT): Mention that
11089 (_AC_OUTPUT_HEADER): Revert the change from 2006-05-19.
11091 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
11093 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT):
11094 Import the following fix from coreutils:
11096 2006-01-13 Jim Meyering <jim@meyering.net>
11098 Invoke AC_CHECK_FUNCS(getmntent) unconditionally so that tests of
11099 $ac_cv_func_getmntent (e.g., in gl_LIST_MOUNTED_FILE_SYSTEMS) need
11100 not double-quote uses of that variable, to accommodate the rare
11101 case in which getmntent is available in none of the libraries
11102 checked. This happens at least on FreeBSD 5.0.
11104 2006-05-20 Paul Eggert <eggert@cs.ucla.edu>
11106 * lib/autoconf/general.m4 (AC_CONFIG_AUX_DIRS): Bring back
11107 ac_config_guess, ac_config_sub, and ac_configure, since evidently
11108 some other programs unwisely rely on these undocumented vars.
11109 But put in warning comments about them.
11110 Problem reported by Ralf Wildenhues in
11111 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00068.html>.
11112 * NEWS: Document that these variables are intended to go away.
11114 2006-05-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11116 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): Require AC_PROG_CXX,
11117 and set the language to C++ (analogous to the equivalent Fortran
11120 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): New macro.
11121 * doc/autoconf.texi (C++ Compiler): Document it.
11122 * lib/autoconf/fortran.m4 (_AC_PROG_FC_C_O): Adjust comment.
11125 2006-05-19 Paul Eggert <eggert@cs.ucla.edu>
11127 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Fix off-by-one bug
11128 that caused config.status to generate 100-command sed scripts; the
11129 portable limit is 99.
11131 2006-05-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11133 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Name temporary
11134 variable `ac_d' instead of `d' to avoid infringing namespace.
11135 Report by Ralf Menzel.
11137 2006-05-18 Paul Eggert <eggert@cs.ucla.edu>
11139 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Don't prepend
11140 $ac_top_build_prefix to $MKDIR_P if it's just 'mkdir -p'.
11141 * tests/tools.at (autoconf: subdirectories): New test, taken from
11142 the corresponding problem report by Ralf Wildenhues in:
11143 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00053.html
11145 * lib/autoconf/functions.m4 (AC_REPLACE_FNMATCH, AC_FUNC_FNMATCH_GNU):
11146 Quote some uses of shell variables if they might suffer unexpected
11147 globbing. This doesn't fix all instances of quoting problems that
11148 I found, just the easy ones that look safe.
11149 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR, _AC_INIT_HELP):
11150 (AC_CONFIG_AUX_DIR, AC_CONFIG_AUX_DIR_DEFAULT, AC_CONFIG_AUX_DIRS):
11151 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST, AC_CANONICAL_TARGET):

11166 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11168 * bin/autoreconf.in: Pass the directory argument to
11169 `require_configure_ac'. Fix comment.
11170 * tests/torture.at (Configuring subdirectories): Expose this.
11171 Reported by Olly Betts.
11173 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11175 * lib/Automake/Configure_ac.pm, lib/Automake/Channels.pm,
11176 lib/Automake/FileUtils.pm, lib/Automake/Struct.pm: Sync from
11177 Automake as follows:
11179 * lib/Autom4te/Configure_ac.pm (find_configure_ac): Use
11180 `$configure_in' instead of `configure.in', to preserve
11181 directory component.
11183 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11185 * config/config.guess, config/config.sub, config/texinfo.tex,
11186 doc/make-stds.texi, doc/standards.texi: Sync from upstream.
11188 2006-05-14 Paul Eggert <eggert@cs.ucla.edu>
11190 * lib/autoconf/headers.m4 (AC_HEADER_STDBOOL): Fix overly-picky
11191 test for C99 conformance; (bool) 0.5 is an integer constant
11192 expression, but (bool) -0.5 is not. Problem reported by Fedor
11193 Sergeev in <http://forum.sun.com/jive/thread.jspa?threadID=96202>.
11195 2006-05-13 Paul Eggert <eggert@cs.ucla.edu>
11197 * doc/autoconf.texi (Particular Programs): AC_PROG_MKDIR_P now
11198 sets MKDIR_P, not mkdir_p, to avoid collisions with Automake.
11199 Warn about obsolete install-sh files. Remove stray sentence
11200 fragment and fix cross reference.
11201 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Don't insist on
11202 install -d; this undoes the 2006-05-10 change.
11203 (MKDIR_P): Mark with AN_MAKEVAR.
11204 (AC_PROG_MKDIR_P): Fall back on $ac_install_sh, not $INSTALL, so
11205 that we don't require $INSTALL to be thread-safe. Move comments
11206 out of generated code. Require AC_CONFIG_AUX_DIR_DEFAULT instead
11207 of AC_PROG_INSTALL. Output a message saying that we're checking
11208 mkdir -p. Set MKDIR_P rather than mkdir_p. Do special magic for
11209 MKDIR_P instead of AC_SUBST.
11210 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE, _AC_OUTPUT_CONFIG_STATUS):
11211 Special magic for MKDIR_P, too.
11212 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Remove comment that defeated
11214 * tests/local.at (AT_CHECK_ENV): mkdir_p -> MKDIR_P.
11216 2006-05-11 Paul Eggert <eggert@cs.ucla.edu>
11218 Sync from Automake, as follows:
11220 2006-05-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11221 * config/install-sh: Initialize IFS, so field splitting isn't
11223 * config/mkinstalldirs: Likewise.
11224 * config/missing: Remove superfluous quotes. Replace all uses of
11225 `[' by `test', for consistency, and for..
11226 * config/missing (sed_minuso, sed_output): New variables.
11227 (autom4te, help2man, makeinfo): Use them. Unifies detection of
11228 `-o FILE', `--output FILE', `--output=FILE', stricter regex.
11229 Fixes `missing' to detect `--output' for help2man. Fixes
11230 PR automake/483. Report by Dennis J. Linse.
11231 (autom4te): Document in `missing --help'.
11233 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
11235 * NEWS: New macro AC_PROG_MKDIR_P. AS_MKDIR_P is now more robust.
11236 * config/install-sh: Don't use 'path' to talk about file names,
11237 as per GNU coding standards. Close a race condition reported by Ralf
11238 Wildenhues and Stepan Kasal. There is still a race condition
11239 on hosts that predate Posix 1003.1-1992, but we can't help this.
11240 Don't mishandle weird characters like space on pre-Posix hosts.
11241 Invoke mkdir at most once per dir arg on pre-Posix hosts.
11242 * doc/autoconf.texi (Programming in M4sh): Cross-reference to
11243 AC_PROG_MKDIR_P from AS_MKDIR_P.
11244 (Limitations of Usual Tools): Cross-reference to AC_PROG_MKDIR_P
11245 from mkdir. Mention that Autoconf 2.60 install-sh is safe but
11246 earlier editions are not (including Automake 1.8.3).
11247 Do not suggest mkinstalldirs for thread-safety.
11248 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Insist on an 'install'
11249 that understands -d, so that AC_PROG_MKDIR_P can fall back on $INSTALL.
11250 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Make it more robust in the
11251 presence of special characters and race conditions.
11252 * tests/local.at (AT_CHECK_ENV): Add mkdir_p to the list of variables
11253 in Autoconf's name space.
11255 2006-05-10 Bruno Haible <bruno@clisp.org>
11256 and Paul Eggert <eggert@cs.ucla.edu>
11258 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): New macro, taken
11259 from Automake with minor changes.
11260 * doc/autoconf.texi (Particular Programs): Document AC_PROG_MKDIR_P.
11262 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
11264 * config/install-sh: Update to Automake CVS version, as follows:
11265 2006-04-25 Stepan Kasal <kasal@ucw.cz>
11266 * lib/install-sh: Simplify the expr implementation of dirname.
11267 2006-04-24 Paul Eggert <eggert@cs.ucla.edu>
11268 * lib/install-sh: Handle --, and diagnose unknown options.
11270 2006-05-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11272 * tests/Makefile.am (AUTOTEST): Use `$(MY_AUTOM4TE)' instead of
11273 `./autom4te' to create `./testsuite', since the `all' target
11274 will ensure its presence, but `installcheck' should not create
11275 the uninstalled wrappers.
11277 * tests/torture.at (Unusual Automake input files): Skip if we
11278 detect automake < 1.8.
11280 2006-05-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11282 * lib/autoconf/c.m4 (AC_PROG_CC_STDC): If ac_cv_prog_cc_stdc
11283 is set to `no', then that overrides and sets ac_cv_prog_cc_c89
11284 and ac_cv_prog_cc_c99 to `no', for backward compatibility.
11287 2006-05-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11289 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Take care not to
11290 munge (multiple) white space and other oddities.
11291 * tests/torture.at (AT_CHECK_AC_ARG_VAR): Make sure to M4-escape
11292 single quotes in variable assignment.
11293 (AC_ARG_VAR, configure invocation): Adjust tests to expose this
11294 and similar failures by adding multiple spaces, tabs, and other
11295 special characters.
11296 Report and different test suggested by Francesco Romani
11297 <fromani@gmail.com> and Andrew Church <achurch@achurch.org>.
11299 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): When we escape
11300 single quotes, we only need to search for single quotes; this
11301 both simplifies the search pattern, and makes us less
11302 susceptible to `echo' variations for arguments not containing
11304 (_AC_ARG_VAR_VALIDATE): Likewise.
11306 2006-05-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11308 * doc/autoconf.texi (Special Shell Variables) <IFS>: Document
11309 `$*' and IFS concatenation issue with traditional shells and
11310 bash-2.04. Report by Seanster@Seanster.com.
11312 2006-05-03 Bruno Haible <bruno@clisp.org>
11314 * doc/autoconf.texi (Limitations of Usual Tools): Identify more
11315 precisely which Mac OS X versions have the od problem.
11317 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
11319 * doc/autoconf.texi: Use @option systematically.
11321 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
11322 and Bruno Haible <bruno@clisp.org>
11324 * doc/autoconf.texi (Limitations of Usual Tools): Add a paragraph
11326 (Integer Overflow): Mention the special case of integer division
11329 2006-05-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11331 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Cater for
11332 traditional shells like the Solaris one that do not use the
11333 first IFS character for assembling `$*'.
11334 Prompted by a related report from autoconf_bug@nro.ca.
11336 2006-05-01 Paul Eggert <eggert@cs.ucla.edu>
11337 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11339 * doc/autoconf.texi (Limitations of Builtins, Limitations of Make):
11340 Mention more problems with the -e option.
11342 2006-04-30 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11345 * doc/autoconf.texi (Systemology): Mention the Heirloom Project.
11347 * doc/autoconf.texi (Introduction, Pointers): Use `@/' liberally
11348 in URLs to improve DVI formatted output (requires texinfo 4.6).
11349 (System Services, Systemology, Shellology): Likewise.
11350 (Limitations of Usual Tools): Rewrite Mac OS X example for nicer
11353 * doc/autoconf.texi (Fortran Compiler): Do not use `@ovar' in
11355 (Runtime): Fix macro argument names to match description:
11356 `action-if-found' -> `action-if-true' and similarly.
11357 (Obsolete Macros): Likewise.
11358 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE): Likewise.
11359 (AC_COMPILE_IFELSE, AC_TRY_COMPILE, _AC_LINK_IFELSE)
11360 (AC_LINK_IFELSE, AC_TRY_LINK, AC_COMPILE_CHECK): Likewise.
11362 2006-04-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11364 * doc/autoconf.texi (Limitations of Make): Clean up markup.
11367 * doc/autoconf.texi (Portable Shell): Allow wrapped URLs, for
11370 2006-04-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11372 * doc/autoconf.texi (Limitations of Builtins): Document FreeBSD
11373 /bin/sh set unsorted output.
11374 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): Adjust.
11375 * tests/local.at: Likewise.
11377 2006-04-26 Paul Eggert <eggert@cs.ucla.edu>
11379 * doc/autoconf.texi (Portable C and C++, Varieties of Unportability):
11380 (Integer Overflow, Null Pointers, Buffer Overruns):
11381 (Floating Point Portability, Exiting Portably): New sections.
11382 (Writing Test Programs): Fix some langauge. Recommend exiting
11383 with status 1, not merely nonzero. Clarify exit declaration.
11384 (Run Time): Move C exit status stuff to new Exiting Portably section.
11385 (Systemology): Mention Posix and levenez. Update v7 reference.
11386 (Portable Shell): Mention the Posix shell.
11388 2006-04-25 Stepan Kasal <kasal@ucw.cz>
11390 * bin/autoconf.as (me): Replace by as_me.
11392 2006-04-25 Paul Eggert <eggert@cs.ucla.edu>
11394 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Don't use AS_ERROR,
11395 since as_me isn't set yet.
11397 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
11399 Prepare for deprecation of AS_BASENAME and AS_DIRNAME, and fix
11400 a few minor bugs in this area.
11402 * doc/autoconf.texi (Programming in M4sh): Comment out the
11403 documentation of AS_BASENAME, for now.
11404 (Shell Substitutions): Do not use AS_DIRNAME in an example.
11405 (Limitations of Builtins) <basename>: Do not refer to
11407 * bin/autoconf.as (me): Don't use AS_BASENAME.
11408 (dir): Remove the unused variable.
11409 * lib/m4sugar/m4sh.m4 (_AS_DETECT_REQUIRED): Renamed from
11410 AS_DETECT_REQUIRED. All uses changed.
11411 (_AS_DETECT_SUGGESTED): Renamed from AS_DETECT_SUGGESTED.
11413 (_AS_DETECT_BETTER_SHELL): Put ;; at the end of a case.
11414 (AS_BASENAME): Use "basename --" to protect against leading "-".
11415 (_AS_BASENAME_EXPR): Renamed from AS_BASENAME_EXPR. All uses changed.
11416 (_AS_BASENAME_SED): Renamed from AS_BASENAME_SED. All uses changed.
11417 (_AS_BASENAME_PREPARE): Reject implementations that cannot handle "--".
11418 (_AS_DIRNAME_PREPARE): Likewise.
11419 (_AS_DIRNAME_EXPR): Renamed from AS_DIRNAME_EXPR. All uses changed.
11420 (_AS_DIRNAME_SED): Renamed from AS_DIRNAME_SED. All uses changed.
11421 (AS_DIRNAME): Use "dirname --".
11423 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
11425 * doc/autoconf.texi (Runtime): Renamed from "Run Time". All uses
11426 of "run time" and "run-time" changed to "runtime", for consistency.
11427 * lib/autoconf/fortran.m4: Likewise (in comment).
11428 * lib/autoconf/functions.m4: Likewise.
11429 * lib/autoconf/general.m4: Likewise.
11430 * lib/autoconf/headers.m4: Likewise.
11432 * doc/autoconf.texi (Run Time): Document the exit status situation
11433 with more accuracy and detail.
11435 2006-04-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11437 * doc/autoconf.texi (Introduction): The GNU Autoconf Macro
11438 Archive is not officially `GNU' any more. Update URL.
11439 (Defining Directories): Likewise
11440 * lib/autoconf/c.m4 (AC_C_RESTRICT): Update URL.
11442 2006-04-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11444 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Remove the leading
11445 newline from the `trap' code to finish `config.log'; the NetBSD
11446 /bin/sh resets the exit status after an empty command, as
11447 documented in doc/autoconf.texi.
11448 Reported by Dalibor Topic <robilad@kaffe.org>.
11450 2006-04-19 Paul Eggert <eggert@cs.ucla.edu>
11452 * doc/autoconf.texi (C Compiler): Clarify AC_C_TYPEOF.
11453 Suggested by Bruno Haible.
11455 2006-04-18 Paul Eggert <eggert@cs.ucla.edu>
11457 * configure.ac (ac_cv_sh_n_works): Don't try to test for it, since
11458 some shells (e.g., Solaris 8 /bin/sh) implement it verrrry slowly.
11459 Instead, just list the shells that we know work.
11460 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Remove 2nd arg. All uses
11461 changed. Be more cautious about the _cv_ variable.
11462 * tests/tools.at (Syntax of the shell scripts): Check the
11463 _cv_ variable once, at first, to avoid an internal autoconf error
11464 when sh -n does not work.
11466 2006-04-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11468 * lib/Autom4te/FileUtils.pm: Sync from Automake.
11470 2006-04-16 Paul Eggert <eggert@cs.ucla.edu>
11472 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Don't
11473 use ">&-" since we're only 99.999% sure that this is portable,
11474 and since the MinGW bug is fixed in a different way.
11475 * lib/autotest/general.m4 (AT_INIT): Likewise.
11477 2006-04-16 Stepan Kasal <kasal@ucw.cz>
11479 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Handle --recheck
11480 before opening config.log, to avoid hitting a bug on MinGW.
11482 2006-04-14 Paul Eggert <eggert@cs.ucla.edu>
11484 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Close
11485 AS_MESSAGE_LOG_FD before reopening it onto the log file.
11486 This works around a MinGW bug reported by Eric Paire.
11487 Make sure that all writes to the log file append to it,
11488 rather than possibly losing data.
11489 * lib/autotest/general.m4 (AT_INIT): Likewise.
11491 2006-04-14 Stepan Kasal <kasal@ucw.cz>
11493 * lib/Autom4te/FileUtils.pm (find_file): Fix a typo in the
11496 2006-04-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11500 * configure.ac (AC_INIT): Bump to 2.59d.
11502 2006-04-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11506 * Makefile.maint (news-date-check): Do not require a leading `*'
11507 before the release date in NEWS.
11509 2006-04-12 Stepan Kasal <kasal@ucw.cz>
11510 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11512 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If the templates for
11513 the instantiated file do not contain the string 'datarootdir'
11514 but contain @datadir@, @docdir@, @infodir@, @localedir@, or
11515 @mandir@, replace the reference '${datarootdir}' by the value.
11516 * tests/torture.at (datarootdir workaround): New test.
11517 * NEWS: Advertise this temporary fixup.
11518 Based on a patch by Bruno Haible, reported and analyzed by
11519 Paul Eggert and Noah Misch.
11521 2006-04-12 Eric Blake <ebb9@byu.net>
11523 * tests/autotest.at (Debugging a failed test): Fix comment.
11525 2006-04-12 Stepan Kasal <kasal@ucw.cz>
11527 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): Simplify the summary of
11528 all the changes since 2006-04-07.
11530 2006-04-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11532 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): If `ln -s file1 file2'
11533 succeeded, but `ln -s file dir' failed, take care to remove the
11534 leftover target before the next test, to prevent its spurious
11535 failure; also make sure `ln file dir' works before selecting it.
11536 Thanks to Keith Marshall for pointing this out.
11539 * lib/autotest/general.m4 (AT_INIT): Store quoted variable
11540 assignments in `at_debug_args', so that we put them correctly
11541 in the `run' script.
11542 * tests/autotest.at (Debugging a failed test): Unmark XFAIL.
11543 Reported by Eric Blake.
11545 2006-04-11 Eric Blake <ebb9@byu.net>
11547 * tests/autotest.at (AT_CHECK_AT): Add new argument, to allow
11548 top-level tests after micro-suite has been run. Used in...
11549 (Debugging a successful test, Debugging script and environment),
11550 (Debugging a failed test): ...these new tests. The first of these
11552 * lib/autotest/general.m4 (_AT_CREATE_DEBUGGING_SCRIPT): New
11553 macro, split out from...
11554 (AT_INIT): ...here, so that using -d also generates a run script.
11555 Document that -d inhibits top-level logging.
11556 * doc/autoconf.texi (testsuite Invocation): Document that -d only
11557 inhibits top-level logging; debug scripts are created.
11559 * lib/autotest/general.m4 (_AT_CHECK): Avoid syntax error on empty
11561 * tests/autotest.at (Empty test, Empty check): New test to check it.
11563 * lib/autoconf/c.m4 (AC_C_CONST, AC_C_VOLATILE): Avoid warnings
11566 2006-04-10 Stepan Kasal <kasal@ucw.cz>
11568 * tests/mktests.sh: Use "trap '' 0", not "trap 0". Do not touch
11569 the files if a problem appears. Make the empty *.at files
11570 read-only, too. Proposed by Ralf Wildenhues.
11572 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11574 * config/Makefile.am: Add comment to force updated Makefile.in.
11576 * lib/freeze.mk: Fix typo in comment. Unlike the last, white
11577 space only patch to this file, this patch causes the Makefile.in
11578 files that include freeze.mk to be updated, and thus have a
11579 newer time stamp again, which in turn makes a pristine CVS
11580 checkout have correct time stamps.
11582 * Makefile.maint (cvs-sv): New macro, to be used..
11583 (config.guess-url_prefix, config.sub-url_prefix)
11584 (texinfo.tex-url_prefix, standards.texi-url_prefix): ..here;
11585 point to CVS text checkout of Gnulib files.
11586 (copyright-check): Bump current year.
11587 (announcement): Do not hard-wire `./announce-gen'.
11588 (cvs-update): Propagate failures of `cvs' and `move-if-change'
11590 * Makefile.cfg (executable-update): Use `chmod a+x' instead of
11592 (wget_files): Update config.guess, config.sub, texinfo.tex by
11593 `wget-update', now that their URLs work again.
11595 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
11597 * doc/autoconf.texi (Particular Types): Don't use AC_CHECK_TYPE.
11598 Problem noted by Paul D. Smith.
11600 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11602 * doc/autoconf.texi: Remove unused words from word list.
11603 * .x-sc_prohibit_atoi_atof, .x-sc_space_tab, .x-sc_sun_os_names,
11604 .x-sc_trailing_space: New files.
11606 * doc/standards.texi: Sync from gnulib.
11608 * NEWS, doc/autoconf.texi (AC_LIBOBJ vs LIBOBJS): Mark
11609 `LIBOBJDIR' as experimental.
11611 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): MSYS `ln -s' fails
11612 with a target directory; it's internally implemented as `cp'
11613 anyway, but since Autoconf advertises the possibility to use
11614 a target directory when LN_S is `ln -s', we need to find out.

11622 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Just output
11623 confdefs.h as-is. In general, if it has backslash-newline or the
11624 like, then it doesn't work either to sort or to remove empty

11638 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Use '\'' for an
11639 apostrophe within a single-quoted string, as this is the usual
11640 tradition and is easier to read than '"'"'. Don't rely on the
11641 shell treating "$/" like '$/'. Use a more-consistent indenting
11642 style for the trap.
11644 2006-04-09 Eric Blake <ebb9@byu.net>

11730 Revert the patch from 2006-04-01 and only improve
11731 _AS_DETECT_BETTER_SHELL:
11733 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Do not optimize; do not
11734 skip nonexistent directories.
11735 (_AS_DETECT_BETTER_SHELL): The optimization is moved here--try
11736 only shell candidates which exist.
11737 (AS_UNAME): No need to give three parameters to _AS_PATH_WALK.
11738 * lib/autotest/general.m4 (AT_INIT): No need to give three

11786 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): Fix the detection of
11787 whether `set' quotes correctly: redirect stderr of the tested
11788 `set', and use a subshell, for Ultrix; use `sed' instead of
11789 `grep' for zsh `set' which may write binary output; match only
11790 at the beginning of a line, to avoid false positives.
11791 In order to avoid false positives by unrelated variables with
11792 multiline content, put the dump algorithm in a subshell and
11793 unset all variables containing newlines (except some which are
11794 special to the shell). Warn about cache variables that are

11841 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_LINKS):
11842 (AC_CONFIG_COMMANDS): Do not do so here.
11843 (_AC_CONFIG_REGISTER_DEST): Double quote the tags in macros _AC_LIST_TAGS
11844 and_AC_LIST_TAG_COMMANDS; fixes another regression introduced by the
11845 2005-07-25 rewrite. Noticed by Noah Misch.
11847 * lib/autoconf/general.m4 (AC_PRESERVE_HELP_ORDER): Do not define

11851 * lib/autoconf/general.m4 (AC_ARG_VAR): Do not use m4_divert_once

11898 (AC_CONFIG_COMMANDS): Append NAME to ac_config_commands without
11899 normalizing it, consistent it with previous releases.

11910 Prefer 'sort -u' to 'sort | uniq'. Filter data before sorting it.
11911 Use 'comm' rather than N instances of grep; this also fixes a bug
11912 whereby substrings were incorrectly matched, causing us to not
11913 generate tests for AC_F77_NAME_MANGLING and AC_FUNC_LSTAT.
11914 (exclude_list): Exclude empty macros.

11998 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't try to
11999 detect exeext, it will be done by _AC_COMPILER_EXEEXT_O; just set
12000 ac_file to the name of the default output file and call
12001 _AC_COMPILER_EXEEXT_WORKS. Move the definition of ac_files and the
12002 initial `rm' of the candidate files...
12003 (_AC_COMPILER_EXEEXT): ... here and simplify them. Moreover, use
12004 the same list in subsequent `rm' calls, and for the temporary
12005 redefinition of ac_clean_files; call _AC_COMPILER_OBJEXT at the end,
12006 and don't call the other _AC_COMPILER_EXEEXT_* macros directly, use...
12007 (_AC_COMPILER_EXEEXT_TESTS): ... this new macro.
12008 (_AC_COMPILER_EXEEXT_O): Don't export ac_cv_exeext, it's not needed (or
12009 no longer needed) by libtool. Make it a cache check.
12010 (_AC_COMPILER_EXEEXT_CROSS): Remove the comment, it was obviously
12011 copied here by mistake.

12788 AC_LANG_FUNC_LINK_TRY. This involves returning the value returned
12789 by the function rather than ignoring it.
12790 (AC_LANG_FUNC_LINK_TRY(C)): Call the function rather than simply
12791 comparing its address. Intel's interprocedural optimization was
12792 outsmarting the old heuristic. Problem reported by

12812 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Balance parentheses.
12813 * lib/autotest/general.m4 (AT_INIT): If the test dir already exists,

12841 suggested by Ben Elliston. Handle weird characters correctly.
12843 2005-09-06 Stepan Kasal <kasal@ucw.cz>
12845 * lib/autoconf/libs.m4 (AC_SEARCH_LIBS): Merge the two AC_LINK_IFELSE
12846 calls, so that the final expansion of this macro is shorter.
12847 Create the conftest.$ac_ext outside the `for' loop, to speed the run.
12848 Do not use `break' in the argument to AC_LINK_IFELSE, it would skip
12849 the cleanup there. Use AS_VAR_* macros, to be more general.

12879 * lib/autoconf/general.m4 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST,
12880 AC_CANONICAL_TARGET): Define by AC_DEFUN, no need to use AC_DEFUN_ONCE;

12896 Stepan Kasal <kasal@ucw.cz>

12899 first header appears, define AH_HEADER.
12900 * doc/autoconf.texi (Configuration Headers): Document AH_HEADER.
12901 Update limitations about when to call AC_CONFIG_HEADERS.
12902 (Configuration Commands): Document that AC_CONFIG_COMMANDS_PRE
12903 parameter can call AC_SUBST, AC_DEFINE, or AC_CONFIG_FOOS; explain
12904 that AC_CONFIG_COMMANDS_PRE and AC_CONFIG_COMMANDS_POST are not
12905 ``Configuration Actions''; fix their index entries.
12907 * lib/autotest/general.m4 (AT_INIT): Process multiple keywords
12908 options correctly. Process N-M as M-N if M is smaller than N.
12909 Process ranges correctly so that N-N will run only N.

12917 before passing the macro name to AH_TEMPLATE.
12919 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): config.status

12944 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Do this; to recognize
12945 build in place, we need ac_pwd, and thus have to AC_REQUIRE ...
12946 (_AC_INIT_DIRCHECK): ... this macro and AC_DEFUN both of them.
12947 * lib/autoconf/status.m4 (_AC_SRCDIRS): Fix a comment: srcdir="."

12966 * lib/autotest/general.m4 (_AT_DECIDE_TRACEABLE): The symbol at_reason
12967 was pushdef'ed twice while popped only once. Push it only once.
12968 (_AT_CHECK): Cosmetic changes to the "case $at_status" command.
12970 2005-07-26 Stepan Kasal <kasal@ucw.cz>
12972 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): The message is now
12973 prefixed by mere "===", not "configure: === ".
12975 2005-07-25 Paul Eggert <eggert@cs.ucla.edu>
12977 * Makefile.maint: Update from Bison.
12979 * lib/m4sugar/m4sugar.m4 (m4_strip): Comment fix---change tab to
12980 "<tab>" in comment, so that the point is understandable.
12982 2005-07-25 Stepan Kasal <kasal@ucw.cz>
12984 Rewrite substantial part of lib/autoconf/status.m4.
12985 The main change is that CONFIG_FILES, CONFIG_HEADERS, CONFIG_LINKS,
12986 and CONFIG_COMMANDS are not processed in four separate loops.
12987 Instead, there is one main loop. This alows that the common code
12988 is expanded only once, thus config.status (and configure) is smaller.
12990 The registration mechnism in AC_CONFIG_FILES and cousins also changed;
12991 the AC_LIST_FILES and cousins macros are no longer used.
12993 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES, _AC_OUTPUT_HEADERS,
12994 _AC_OUTPUT_LINKS, _AC_OUTPUT_COMMANDS): Renamed to ...
12995 (_AC_OUTPUT_FILE, _AC_OUTPUT_HEADER, _AC_OUTPUT_LINK,
12996 _AC_OUTPUT_COMMAND): ..., respectively. These macros no longer
12997 contain the initialization, nor the for loop, nor the associated
12998 commands; all these go to ...
12999 (_AC_OUTPUT_MAIN_LOOP): ... this new macro, called from
13000 _AC_OUTPUT_CONFIG_STATUS.
13001 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST, _AC_CONFIG_SPLIT_FILE_IN):
13002 Nuked; the code was merged into _AC_OUTPUT_MAIN_LOOP.
13003 (_AC_OUTPUT_FILE): The creation of the sed script ...
13004 (AC_OUTPUT): ... and the setup of ac_vpsub goes to ...
13005 (_AC_OUTPUT_FILES_PREPARE): ... a new macro, also called from
13006 _AC_OUTPUT_MAIN_LOOP.
13007 (_AC_CONFIG_FILES, _AC_CONFIG_HEADERS, _AC_CONFIG_LINKS,
13008 _AC_CONFIG_COMMANDS): Use ...
13009 (_AC_CONFIG_FOOS): ... this new macro, which uses these ...
13010 (_AC_CONFIG_REGISTER, _AC_CONFIG_REGISTER_DEST): ... new macros.
13011 (_AC_CONFIG_FILE, _AC_CONFIG_HEADER, _AC_CONFIG_LINK,
13012 _AC_CONFIG_COMMAND, _AC_CONFIG_DEPENDENCIES): No longer needed.
13013 (_AC_CONFIG_DEPENDENCY): Update, it uses these ...
13014 (_AC_CONFIG_DEPENDENCY_DEFAULT, _AC_FILE_DEPENDENCY_TRACE_COLON):
13016 (_AC_CONFIG_UNIQUE): Update.
13017 (AC_LIST_FILES, AC_LIST_HEADERS, AC_LIST_LINKS, AC_LIST_COMMANDS):
13018 Replaced by this ...
13019 (_AC_LIST_TAGS): ... new common macro.
13020 (AC_LIST_FILE_COMMANDS, AC_LIST_HEADER_COMMANDS, AC_LIST_LINK_COMMANDS,
13021 AC_LIST_COMMAND_COMMANDS): Replaced by this ...
13022 (_AC_LIST_TAG_COMMANDS): ... new common macro.
13023 (_AC_CONFIG_COMMANDS_INIT): Moved top to the `registration' section;
13024 this didn't belong to the `config commands' section.
13025 (_AC_OUTPUT_COMMANDS_INIT): Don't initialize, m4_ifdef is our friend.
13026 (AC_CONFIG_COMMANDS_PRE, AC_OUTPUT_COMMANDS_PRE,
13027 AC_CONFIG_COMMANDS_POST): Moved to a new section, these didn't belong
13028 to the `config commands' section either.
13029 (AC_CONFIG_SUBDIRS): Don't touch diversion DEFAULTS.
13030 (_AC_LIST_SUBDIRS): Don't initialize, m4_ifdef is our friend.
13032 ... and many changes to the comments nearby.
13034 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): At the end of the day,
13035 set ac_subdirs_all='_AC_LIST_SUBDIRS'.
13036 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
13037 AC_CONFIG_COMMANDS(command:input,...) is no longer allowed.
13038 (#define header templates): The comment at the top of the generated
13039 header now includes the name(s) of the source file(s).
13041 Several unrelated small changes:
13043 * lib/autoconf/general.m4 (AC_CACHE_VAL): Be didactic, quote the first
13044 parameter to AC_DIAGNOSE.
13045 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS): Likewise.
13046 (_AC_LINK_FILES_CNT): Don't AU_DEFUN this; it causes confusing messages
13047 with autoupdate; use m4_define_default inside AU_DEFUNed AC_LINK_FILES.
13048 (AC_OUTPUT): In the compatibility code, use m4_ifvaln, to be consistent
13049 with AU::AC_OUTPUT.
13050 (AU::AC_OUTPUT): Don't double-quote $2 and $3, the compatibility code
13051 in AC_OUTPUT doesn't double-quote it either.
13052 * tests/tools.at (autoupdate): AU::AC_OUTPUT no longer double-quotes the
13055 2005-07-10 Stepan Kasal <kasal@ucw.cz>
13057 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Document which
13058 versions of Portland Group compiler produce single- and double-quoted
13059 -cmdline argument. Reported by Steven G. Johnson <stevenj@fftw.org>

13062 2005-07-07 Paul Eggert <eggert@cs.ucla.edu>
13064 * tests/local.at (AT_CONFIG_CMP): Ignore lines like "LIBS=''" too.
13065 This is a corrected version of yesterday's patch.
13067 2005-07-07 Stepan Kasal <kasal@ucw.cz>
13069 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Report the full
13070 path, too; insert a "===" to emphasize the line.
13072 * lib/autoconf/general.m4 (AC_CANONICAL_BUILD): Rename
13073 ac_cv_build_alias to ac_build_alias.
13074 (AC_CANONICAL_HOST, AC_CANONICAL_TARGET): Simplify.
13076 On 2005-02-24, an unintentional AC_SUBST([CC]) was introduced; this
13077 change eliminates it. Problem reported by Alexandre Duret-Lutz.
13078 * lib/autoconf/general.m4 (_AC_ARG_VAR_PRECIOUS): Move the AC_SUBST ...
13079 (AC_ARG_VAR): ... here.
13080 (_AC_INIT_PREPARE): Call AC_SUBST for build_alias, host_alias and
13083 Keep a list of all precious variables and process them with one simple
13084 for loop, instead of expanding all commands, or, OTOH, complicated
13085 processing of output of "set".
13086 * lib/autoconf/general.m4 (_AC_ARG_VAR_PRECIOUS): Acumulate the
13087 variable names in new macro...
13088 (_AC_PRECIOUS_VARS): ... which will be assigned to ac_precious_vars.
13089 (_AC_ARG_VAR_STORE): New macro which writes to diversion PARSE_ARGS
13090 a loop to assign all ac_env_* and ac_cv_env_* variables.
13091 (_AC_ARG_VAR_VALIDATE): Use shell variable ac_precious_vars, divert
13093 (_AC_INIT_DEFAULTS): At the end, if _AC_PRECIOUS_VARS is set, assign
13094 its value to shell variable ac_precious_vars and call
13095 _AC_ARG_VAR_STORE and _AC_ARG_VAR_VALIDATE.
13096 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Don't call
13097 _AC_ARG_VAR_VALIDATE.
13099 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Move AC_LANG_PUSH(C)

13118 They are generated by the Tru64 v5.1B shell.
13120 2005-07-05 Stepan Kasal <kasal@ucw.cz>
13122 Fix my changes from 2005-07-01; reported by Noah Misch.
13123 * lib/autoconf/status.m4 (_AC_CONFIG_DEPENDENCIES): Fix the
13124 description, the macro now accepts only a single tag.
13125 (_AC_CONFIG_UNIQUE): Likewise; s/AC_File/[$1]/
13127 Fix cases when the varsions of Autoconf and Autotest don't match.
13128 Reported by Noah Misch.
13129 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Set also
13130 at_top_builddir, for compatibility with older autotest.
13131 * lib/autotest/general.m4 (AT_INIT): If at_top_build_prefix
13132 is not set, use at_top_builddir, for compatibility with older

13137 * bin/autom4te.in ($m4): Catch usages like --nesting-limit=2048.
13138 Problem reported by Patrick Welche.
13140 2005-07-03 Paul Eggert <eggert@cs.ucla.edu>
13142 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Use &, not |, in
13143 sed substitution command, so that we allow | in program prefixes
13144 and program suffixes. (& is a problem anyway; we're not fixing
13146 * lib/autoconf/status.m4 (AC_CONFIG_FILES): Likewise, for
13147 configure_input, top_builddir, srcdir, etc.
13148 * lib/autotest/general.m4 (AT_INIT): Likewise, for
13149 PATH_SEPARATOR in AUTOTEST_PATH.
13151 2005-07-02 Alexandre Duret-Lutz <adl@gnu.org>
13153 * lib/autoconf/general.m4 (AC_SITE_LOAD): Rewrite the
13154 for loop over config.site files using `set', to allow
13155 directory names containing IFS characters.
13157 2005-07-01 Paul Eggert <eggert@cs.ucla.edu>
13159 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Remove the tests for
13160 directories with weird names. Apparently some people like living
13161 on the edge. However, improve the test that "pwd" actually does
13162 report a name for the working directory.

13179 (Limitations of Usual Tools) <sed>: Another minor rephrasing.
13181 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Use a here
13182 document to output the default config_* lists to config.status.
13183 Don't recognize option --file, if the functionality is not there.
13184 Likewise for --header; moreover, recognize --he and --h as shortcuts
13185 for --help in that case.
13187 * lib/autoconf/status.m4: Fix the order of the "sections", so that it
13188 matches the order of execution. No code changed.
13190 2005-06-30 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

13207 * lib/autoconf/general.m4 (AC_ARG_VAR): Move next to _AC_ARG_PRECIOUS.
13209 * lib/autoconf/general.m4 (AC_SUBST_TRACE): New macro, to be traced
13210 instead of AC_SUBST; proposed by Alexandre Duret-Lutz.
13211 (AC_SUBST): Call it.
13212 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Call AC_SUBST_TRACE for
13213 the directory specific variables; but don't call it for configure_input.
13215 2005-06-28 Derek Price <derek@ximbiot.com>
13217 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: Reword recent
13220 2005-06-23 Paul Eggert <eggert@cs.ucla.edu>
13222 * NEWS: Don't worry about spaces in bindir etc. Only srcdir and working
13223 directory have inherent problems with special characters like spaces,
13224 due to limitations in Make syntax. Problem reported by Alexandre
13226 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Implement the above.
13227 Also, fix Tru64 porting problem with shell patterns,

13239 from Justace Clutter.
13240 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Put name of invalid
13241 variable into diagnostic. Make the diagnostic an error, not a warning,
13242 because we really don't support spaces and suchlike in dir names.
13243 (_AC_INIT_SRCDIR): Allow special characters in $ac_unique_file.
13244 Don't worry about backslashes in srcdir; it can't happen now.
13245 (_AC_INIT_PARSE_ARGS): Allow weird characters in ac_optarg.
13246 Simplify ac_optarg handling.
13247 (_AC_ARG_VAR_VALIDATE): Remove unnecessary and inconsistent quotes.

13254 * tests/local.at (AT_CHECK_ENV): Use $EGREP, not $GREP -E.
13255 (AT_CONFIG_CMP): Use sed instead of grep plumbing.
13257 * doc/autoconf.texi (Limitations of Usual Tools) <grep>: Mention
13258 that '\|' is not allowed in BREs; recommend using newline separated
13259 list of patterns instead of multiple -e options.
13261 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Remove an old comment.
13263 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Use AC_SUBST/2.

13269 2005-06-21 Stepan Kasal <kasal@ucw.cz>
13271 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: Document that
13272 b, t, r, w commands require single space, while : cannot have any.
13273 (Special Shell Variables): Fix sed code this in the example.
13274 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Likewise; and fix a typo.
13275 * lib/autotest/general.m4 (AT_ARG_OPTION): Fix typo in the description.
13277 * lib/m4sugar/m4sugar.m4 (m4_split): If the parameter is empty,
13278 expand to the empty list. Don't use two pairs of m4_changequote,
13279 it's not necessary.
13281 2005-06-20 Derek Price <derek@ximbiot.com>
13283 * lib/m4/programs.m4 (AC_PROG_YACC): Declare YACC & YFLAGS precious.
13285 2005-06-17 Paul Eggert <eggert@cs.ucla.edu>
13287 * lib/m4sugar/m4sh.m4 (as_awk_strverscmp): Port to Solaris /bin/awk.
13288 * doc/autoconf.texi:
13289 Don't mention Solaris versions so much, if a
13290 problem is common to all extant versions of Solaris. Say "SunOS
13291 4" instead of "SunOS" for SunOS 4.
13292 (awk): Mention more of the limitations of traditional Awk.
13293 (cat): Don't talk about cat -v.

13300 to be compatible with glibc strverscmp.
13301 * tests/m4sh.at (AS_VERSION_COMPARE): New test.
13303 * doc/autoconf.texi (Limitations of Usual Tools): Mention expr bug
13304 on Mac OS X 10.4 reported by Peter O'Gorman in:
13305 http://lists.gnu.org/archive/html/autoconf-patches/2005-06/msg00041.html
13306 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT):
13307 Use shell builtins rather than 'expr', to work around expr bug.
13309 2005-06-10 Paul Eggert <eggert@cs.ucla.edu>
13311 * doc/autoconf.texi: "filesystem" -> "file system".
13312 "behaviour" -> "behavior".
13313 Warn about \(...\)* in Solaris sed (written by Ralf Menzel).
13314 * lib/autoconf/general.m4: Omit blank after ":" sed command,
13316 * lib/m4sugar/m4sh.m4: Likewise.
13317 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Work around problem
13318 with Solaris sed. Fix by Ralf Menzel and Stepan Kasal.

13321 (.x.1): Ignore the time stamp in the .TH line when deciding whether
13322 to update the man page. That way, we don't have to check in new
13323 man pages every month.
13325 * lib/m4sugar/m4sh.m4 (AS_VAR_TEST_SET): Work even if $1 contains
13326 quotes and backslashes. Patch from Derek Price.
13328 2005-06-10 Derek Price <derek@ximbiot.com>
13330 * doc/autoconf.texi (Programming in M4sh): Document AS_TR_CPP &

13335 * lib/autotest/general.m4 (AT_INIT): Don't accept Solaris 9's diff
13336 -u, since it outputs chatter if the input files are the same.
13337 Problem reported by Ralf Menzel.
13339 2005-06-08 Derek Price <derek@ximbiot.com>
13341 * lib/m4sugar/m4sugar.m4: Undefine include & sinclude rather than
13342 renaming them since they are about to be redefined anyhow.
13344 2005-06-08 Derek Price <derek@ximbiot.com>
13346 * doc/autoconf.texi (Redefined M4 Macros): Add index entries for most
13347 redefined M4 macros to this node. Document m4_include & m4_sinclude.
13348 Move m4_undefine to alphabetical order.
13350 2005-06-07 Paul Eggert <eggert@cs.ucla.edu>
13352 * README: Recommend GNU M4 1.4.3 or later.
13353 * doc/autoconf.texi (Introduction): Likewise.
13354 Reword to avoid some formatting glitches.
13355 Use "#!/bin/sh", not "#! /bin/sh"; the space isn't needed these days.
13356 Clarify explanation of HP compiler bug.
13357 Redo example output tp match current CVS snapshot.
13358 Use @example.org in email addresses when the examples
13359 might get inadvertently cut-and-pasted into user code.
13360 Remove example of autom4te usage that doesn't seem to work now.
13361 Use modern AC_INIT (except when the example is meant to be
13362 shown with Autoconf 2.13).
13363 Update ksh info for Solaris 9 and later.
13365 Modernize description of Automake versions a bit.
13366 Don't claim a future version of Autoconf is near.
13367 * doc/install.texi: Reword to avoid some formatting glitches.
13369 2005-06-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
13371 * doc/autoconf.texi: Add [] to examples, so that the manual
13372 follows its own advice about quoting better.
13373 Reword to avoid some formatting glitches.
13374 * doc/installt.exi: Reword to avoid some formatting glitches.
13376 * doc/autoconf.texi (Limitations of Builtins) <case>: Mention
13377 Tru64 ksh pattern matching bug. Reported against Libtool by
13378 Albert Chin <libtool@mlists.thewrittenword.com> and
13379 Nicolas Joly <njoly@pasteur.fr>.
13381 2005-06-06 Stepan Kasal <kasal@ucw.cz>
13383 m4_cdr of one-member list was [[]] (one-member list containing an
13384 empty string) instead of [] (an empty list. Callers were skewed to
13385 match this misbehaviour. As a consequence of this:
13386 - m4_foreach([x], [], [foo]) expanded to `foo', while
13387 - the expansion of m4_foreach([x], [[]], [foo]) was empty.
13388 This bug has been fixed:
13390 * lib/m4sugar/m4sugar.m4 (m4_cdr): If only one argument is given,
13391 expand to an empty string; print error msg if called without
13393 (m4_foreach, m4_map, m4_map_sep): Don't expect the previous
13394 misbehaviour; handle [] and [[]] correctly.
13396 2005-06-06 Stepan Kasal <kasal@ucw.cz>
13398 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Nuke ac_max_here_lines.
13399 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Simplify the sed
13400 scripts created and the loop applying them, use _AC_SED_CMD_LIMIT.
13402 2005-06-06 Ralf Menzel <menzel@ls6.cs.uni-dortmund.de> (trivial change)
13404 * doc/autoconf.texi (Limitations of Usual Tools): Solaris' awk cannot
13405 swallow records with more than 99 fields.
13406 * lib/autotest/general.m4 (AT_INIT): Use the awk builtin `split' to
13407 parse the long line.
13409 2005-06-04 Stepan Kasal <kasal@ucw.cz>
13411 * doc/autoconf.texi (Limitations of Usual Tools): AIX awk cannot
13412 swallow literals longer than 399. Reported by Ralf Wildenhues.
13413 * lib/autotest/general.m4 (AT_INIT): Pass $at_groups though stdin,
13414 to workaround this limitation.
13416 2005-06-03 Steven G. Johnson <stevenj@alum.mit.edu>
13418 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Find g95 in addition
13419 to gfortran, and make these the first two compiler names
13420 checked (following the general autoconf preference for gcc).
13422 2005-06-03 Stepan Kasal <kasal@ucw.cz>
13424 * tests/Makefile.am (check_SCRIPTS): Set to $(wrappers).
13425 (DISTCLEANFILES): Remove $(check_SCRIPTS).
13426 (testsuite): Make sure autotest.m4f is up-to-date before using it.
13428 2005-06-02 Paul Eggert <eggert@cs.ucla.edu>
13430 * lib/autotest/general.m4 (AT_INIT): Don't create a regular
13431 expression of unbounded size when processing the --list
13432 option. This runs afoul of a limit of 399 bytes per regular
13433 expression on AIX. Problem reported by Ralf Wildenhues.
13435 2005-06-01 Paul Eggert <eggert@cs.ucla.edu>
13437 * NEWS: Note yesterday's changes to AC_SUBST and AC_SUBST_FILE.
13438 * doc/autoconf.texi (Particular Headers): Reword example
13439 for multiline stdbool replacement.
13440 (Setting Output Variables): Reword text a bit. Don't
13441 give all the details about |#_!!_#|.
13442 Reword description of line replacement.
13444 2005-05-31 Dan Manthey <dan_manthey@partech.com>
13446 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Output variables may
13447 now contain newlines, and substituted files must be referenced on
13448 a line alone; the sed scripts to substitute them are now very
13450 (_AC_SED_CMD_LIMIT): Added; single place to store limit on how many
13451 commands can be put in a sed script portably.
13452 * doc/autoconf.texi (Setting Output Variables): Document above
13453 changes. (Particular Header Checks) <AC_HEADER_STDBOOL>: Give exaple
13454 use of multiline substitution.
13455 * tests/torture.at: No longer expect substitution of newline to fail.
13457 2005-05-27 Paul Eggert <eggert@cs.ucla.edu>
13459 * lib/m4sugar/m4sh.m4 (_AS_SHELL_FN_WORK): Fix diagnostics.
13460 From Ralf Menzel (trivial change).
13462 2005-05-25 Paul Eggert <eggert@cs.ucla.edu>
13464 * tests/local.at: Don't attempt to check for negated character
13465 classes in shell scripts. The test was too brittle.
13467 2005-05-25 Stepan Kasal <kasal@ucw.cz>
13469 * bin/autoconf.as: Don't use "shift 2"; it's not portable enough.
13470 * doc/autoconf.texi (Limitations of Builtins): Document this
13473 2005-05-24 Stepan Kasal <kasal@ucw.cz>
13475 * lib/m4sugar/m4sh.m4 (_AS_ECHO_LOG): New macro to factor out
13476 common code; used in many places in the tree.
13477 (AS_ESCAPE): Make the pattern a bit simpler; use \& insetad of \1.
13478 (_AS_ECHO_UNQUOTED): Move the macro lower; no code change.
13480 * lib/m4sugar/m4sugar.m4 (m4_ifset): Use m4_ifval.
13482 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Merge the two error
13483 messages when ac_unique_file is not found.
13484 (AC_CONFIG_MACRO_DIR): Simplify the `if' at the end.
13485 (AC_MSG_CHECKING, AC_MSG_RESULT): Put braces around the two echo
13486 commands, for consistency with AC_MSG_ERROR and such.
13488 * bin/autoconf.as: Make more use of "shift 2" in option processing.
13490 * bin/Makefile.am: Merge the two rules for creating scripts.
13492 2005-05-23 Stepan Kasal <kasal@ucw.cz>
13494 * lib/autoconf/general.m4 (AC_MSG_RESULT_UNQUOTED): Make
13495 obsolete; it was never documented.
13496 (AC_CACHE_CHECK): Use AC_MSG_RESULT instead.
13498 2005-05-20 Stepan Kasal <kasal@ucw.cz>
13500 * NEWS: @top_builddir@ is now a dirname, ac_top_builddir will follow.
13501 * lib/autoconf/status.m4 (_AC_SRCDIRS): Rename ...
13502 (ac_top_builddir): ... this ...
13503 (ac_top_build_prefix): ... to this; the old name is also kept, for
13504 backward compatibility.
13505 (ac_top_builddir_sub): New variable, without the trailing slash,
13507 (_AC_OUTPUT_FILES): s/@top_builddir@/$ac_top_builddir_sub/
13508 * doc/autoconf.texi (Configuration Actions): Rename
13509 ac_top_builddir to ac_top_build_prefix.
13510 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Rename
13511 at_top_builddir to at_top_build_prefix.
13512 * lib/autotest/general.m4 (AT_INIT): Likewise.
13514 2005-05-20 Stepan Kasal <kasal@ucw.cz>
13516 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Simplify the init
13519 2005-05-17 Stepan Kasal <kasal@ucw.cz>
13521 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Don't m4_quote the second
13522 argument to m4_foreach. I guess it was necessary in the past,
13523 but I think it's a no-op now.
13525 2005-05-17 Stepan Kasal <kasal@ucw.cz>
13527 * lib/autoconf/general.m4 (_AC_INIT_HELP): Merge two consecutive
13528 ``cat <<_ACEOF'' commands to one.
13529 (_AC_CANONICAL_SPLIT): Use expr, not ``echo|sed.''
13530 * lib/autoconf/status.m4: On various places, use expr instead of
13532 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST):
13533 (_AC_CONFIG_SPLIT_FILE_IN): New macros, to factor out common code.
13534 * lib/autotest/general.m4 (AT_INIT): Use expr to get the numbers from
13536 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Use awk to search for
13537 the wrong patterns between ``case'' and ``esac.'' The previous
13538 code had false positives.
13540 2005-05-14 Alexandre Duret-Lutz <adl@gnu.org>
13542 * lib/autoconf/functions.m4 (_AC_LIBOBJ_ALLOCA): Prepend ${LIBOBJDIR},

13585 2005-05-13 Stepan Kasal <kasal@ucw.cz>
13587 * lib/autoconf/general.m4 (AC_CONFIG_LIBOBJ_DIR): Remove the broken
13589 * lib/m4sugar/m4sugar.m4 (m4_bmatch): Halt with error if we don't get
13590 enough arguments, similarly as in m4_bpatsubsts.
13592 2005-05-12 Stepan Kasal <kasal@ucw.cz>
13594 * lib/autoconf/status.m4 (_AC_SRCDIRS): Simplify the computation
13597 2005-05-11 Stepan Kasal <kasal@ucw.cz>
13599 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Make the check
13600 for absolute directory names in one loop.
13601 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Handle
13602 abbreviations of --version and --debug.
13604 2005-05-10 Paul Eggert <eggert@cs.ucla.edu>
13606 * doc/autoconf.texi (Autoconf Language): Be more precise about
13607 quoting rules. Problems noted by Stepan Kasal.
13608 Also, throughout this document, be more careful about white space.
13609 "blank", "white space", and "space" all have different meanings
13610 and we should be careful to say what we mean.
13612 2005-05-05 Paul Eggert <eggert@cs.ucla.edu>
13614 Fix C++ related problems reported by Werner Lemberg.
13615 * doc/autoconf.texi (C++ Compiler): Mention .cpp extension.
13616 * lib/autoconf/c.m4 (AC_LANG(C++)): Set ac_ext to .cpp, not .cc.
13617 * lib/autoconf/types.m4 (AC_TYPE_SIGNAL): Simplify test, to
13618 avoid problems with C++ and throw.
13619 * tests/compile.at: .cpp, not .cc.
13621 * tests/semantics.at: Prepend LIBOBJDIR, as per 2005-05-02 change.
13623 2005-05-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
13625 * doc/autoconf.texi (Generic Functions): Typos.
13627 2005-05-02 Gary V. Vaughan <gary@gnu.org>
13629 * lib/autoconf/general.m4 (_AC_LIBOBJS_NORMALIZE): Prepend each
13630 object named in LIBOBJS and LTLIBOBJS with the ${LIBOBJDIR}, as
13631 set by latest automake.
13633 2005-05-01 Paul Eggert <eggert@cs.ucla.edu>
13635 * doc/autoconf.texi (Limitations of Usual Tools): "expr '' \| ''"
13636 outputs 0 on GNU/Linux these days.
13638 2005-04-29 Paul Eggert <eggert@cs.ucla.edu>
13640 * doc/autoconf.texi (Autoconf Language): Add more description
13641 about quoting heuristics.
13642 (Limitations of Builtins): Describe "set -" problems.
13644 2005-04-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
13646 * lib/autotest/general.m4 (AT_KEYWORDS): Separate by space,
13649 * doc/autoconf.texi (External Software): Replace AC_DEFINE_UNQUOTED
13650 by AC_DEFINE; it was a mistake.
13651 From bug reported against libtool by Dalibor Topic <robilad@kaffe.org>.
13653 2005-04-25 Stepan Kasal <kasal@ucw.cz>
13655 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): A tiny optimization.
13657 2005-04-22 Stepan Kasal <kasal@ucw.cz>
13659 * doc/autoconf.texi (External Software): Quadrigraphs are not
13660 processed correctly in AS_HELP_STRING; avoid this in the examples.
13661 * lib/m4sugar/m4sh.m4 (AS_HELP_STRING): Add a FIXME about quadrigraphs.
13662 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Likewise; and rephrase the
13663 comment and reduce m4_default([foo], []) to [foo].
13664 (m4_strip): Update the explanation.
13666 2005-04-19 Paul Eggert <eggert@cs.ucla.edu>
13668 * lib/autoconf/general.m4 (_AC_INIT_PREPARE, _AC_RUN_IFELSE):
13669 Remove core.conftest.* too; it's generated by Tru64 5.1.
13670 Problem reported by Jennis Pruett.
13671 * lib/autoconf/functions.m4
13672 (AC_FUNC_SETVBUF_REVERSED, AC_FUNC_UTIME_NULL):
13673 Don't bother to remove core files; AC_RUN_IFELSE should do that
13676 2005-04-19 Stepan Kasal <kasal@ucw.cz>
13678 * lib/m4sugar/m4sugar.m4 (m4_bpatsubsts): Add the b- to comment, too.
13680 2005-04-19 Alexandre Duret-Lutz <adl@gnu.org>
13682 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Handle --docdir.
13683 Report from Horst Wente.
13685 2005-04-15 Stepan Kasal <kasal@ucw.cz>
13687 * lib/autoconf/general.m4 (_AC_ARG_VAR_VALIDATE): Fixed a typo in
13690 2005-04-14 Gregorio Guidi <greg_g@gentoo.org>
13692 * doc/autoconf.texi (External Software, Package Options): Add
13693 examples showing how to implement --with-* and --enable-* options.
13695 2005-04-13 Paul Eggert <eggert@cs.ucla.edu>
13697 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Look for configure.ac
13698 as well as configure.in. Problem reported by Gregorio Guidi.
13700 2005-04-10 Paul Eggert <eggert@cs.ucla.edu>
13702 * doc/autoconf.texi (Particular Functions): Use gnulib's current
13703 pattern for alloca snippet.
13705 2005-04-04 Stepan Kasal <kasal@ucw.cz>
13707 * lib/autotest/general.m4 (_AT_DECIDE_TRACEABLE): Fix a typo.

13711 * doc/autoconf.texi (Generic Programs): Fix a typo.
13713 2005-04-01 Paul Eggert <eggert@cs.ucla.edu>
13715 * lib/autotest/general.m4 (AT_INIT): Don't assume that "date +%s"
13716 fails if %s isn't supported. Problem reported by Ralf Wildenhues.
13718 2005-03-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
13720 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS):
13721 Merge `-z option' as well for the benefit of Solaris link flags. Pass
13722 whole-archive (-zallextract, -zdefaultextract) options in the hope of
13723 unique libraries, for the Sun Fortran 95 8.0 compiler. Bug reported
13724 against Libtool by Yury Puhalsky <pooh@cryptopro.ru>.
13726 2005-03-22 Paul Eggert <eggert@cs.ucla.edu>
13728 * NEWS: The configure command now warns you if you attempt to use
13729 a directory whose name contains a special character like space,
13731 * doc/autoconf.texi (Installation Directory Variables): Allow
13732 "," in file names. Do not use \@; it's not a portable regexp.
13733 * bin/Makefile.am (edit): Likewise.
13734 * lib/Makefile.am (edit): Likewise.
13735 * tests/Makefile.am (edit): Likewise.
13736 * tests/semantics.at: Likewise.
13737 * tests/torture.at: Likewise.
13738 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Likewise.
13739 * lib/autoconf/status.m4 (_AC_SRCDIRS): Likewise.
13740 * doc/autoconf.texi (File System Conventions): Warn about
13741 unportable file names.
13742 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): New macro.
13744 (_AC_INIT_SRCDIR): Use ac_pwd rather than invoking pwd.
13745 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Propagate
13746 ac_pwd, and quote srcdir.
13747 * lib/autotest/general.m4 (AT_INIT): Quote file name args.
13749 * doc/autoconf.texi: Fix some systematic formatting problems.
13750 ".)" needs a following @: if not at the end of a sentence, and
13751 similarly for "!)". "etc." should be preceded by a comma.
13752 "n-th" -> "@var{n}th". pdksh is still buggy, so update its date.
13754 2005-03-22 Bruno Haible <bruno@clisp.org>
13756 * doc/autoconf.texi (Input): Mention that AC_CONFIG_AUX_DIR's
13757 argument is often called 'build-aux'.
13759 2005-03-07 Stepan Kasal <kasal@ucw.cz>
13761 * doc/autoconf.texi (Quotation Rule Of Thumb): Mention that the
13762 macro AC_TRY_LINK is obsolete.
13763 (Installation Directory Variables): Change `AC_OUTPUT_FILES' to
13766 2005-02-24 Stepan Kasal <kasal@ucw.cz>
13768 * lib/autoconf/c.m4 (AC_PROG_CC): Be more careful to skip
13769 `/usr/ucb/cc'; use `cl.exe' to distinguish the MS compiler
13770 from a Common Lisp's `cl'.
13771 (AC_PROG_CXX): Behave according to the documentation: don't
13772 search for $ac_tool_prefix$CCC and $CCC, just set CXX=$CCC;
13773 make the variable CCC precious; use `cl.exe', not `cl'.
13775 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
13776 Alexandre Duret-Lutz <adl@gnu.org>
13778 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin from
13779 /dev/null, as "configure" shouldn't read stdin, and this insulates
13780 us from problems (e.g., when testing for "cl"). Also, do this
13781 redirection before invoking "hostname" or "uname", and keep the
13782 original input stream available via...
13783 (AS_ORIGINAL_STDIN_FD): ... this new macro.
13784 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't
13785 bother with "</dev/null" since it's now done at the top of
13787 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Likewise.
13788 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
13789 * lib/autoconf/programs.m4 (_AC_PATH_PROG_FLAVOR_GNU): Likewise.
13790 * doc/autoconf.texi (File Descriptor Macros): New section.
13791 (Printing Messages): Mention it.
13792 * tests/base.at (Input/Output): New test.
13794 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
13796 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N_PREPARE): Don't set ECHO_C to
13797 newline if neither \c nor -n work, as that would output two
13798 newlines. Prefer -n to \c. Reported by Stepan Kasal.
13800 2005-02-12 Stepan Kasal <kasal@ucw.cz>
13802 * lib/m4sugar/m4sh.m4 (AS_IF): Define by m4_defun, not m4_define.
13803 This causes that any required macros inside will get before the if.
13804 * doc/autoconf.texi (autom4te.cache): A typo.
13806 2005-02-12 Paul Eggert <eggert@cs.ucla.edu>
13808 Undo previous change, except keep the change to
13809 lib/autoconf/programs.m4 that replaced grep with shell
13810 pattern-matching. This is because net-snmp configure reads stdin.
13811 Reported by Noah Misch.
13813 2005-02-11 Paul Eggert <eggert@cs.ucla.edu>
13815 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin
13816 from /dev/null, as "configure" shouldn't read stdin, and this
13817 insulates us from problems (e.g., when testing for "cl").
13818 Suggested by Alexandre Duret-Lutz. Also, do this redirection
13819 before invoking "hostname" or "uname".
13820 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
13821 _AC_LINK_IFELSE): Undo previous change, as it's no longer needed.
13822 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Don't bother with
13823 "</dev/null" since it's now done at the top of 'configure'.
13824 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
13825 * lib/autoconf/programs.m4 (_AC_PATH_PROG_FLAVOR_GNU): Likewise.
13826 Also, replace grep with shell pattern-matching, to save a process.

13994 Simplify the implementation of m4_require (a.k.a. AC_REQUIRE).
13995 Update the long comment explaining it.
13997 m4_require no longer writes an ``is required by'' line to the
13998 execution stack. It contains only one bit of non-redundant
13999 information: that the macro was required, not called. And even
14000 this bit is useless in most situations: have you ever met a macro
14001 which both calls and requires the same macro?
14003 * lib/m4sugar/m4sugar.m4 (_m4_defun_pro): Don't push a diversion...
14004 (_m4_defun_pro_outer): ... only via this macro, for the outermost

14049 2005-01-20 Paul Eggert <eggert@cs.ucla.edu>
14051 * doc/autoconf.texi (Shell Substitutions): Fix typo in case statement.
14052 Warn about newline stripping in `` and $(). Update Solaris
14054 (Limitations of Builtins): Use expr "X...", not expr "x...", as

14105 (_m4_divert_n_stack): New macro; the expansion is
14106 <newline>m4_divert_stack, if m4_divert_stack is defined, and void
14108 (m4_divert, m4_divert_push, m4_divert_pop, m4_init): Use it.
14109 (m4_divert_push, m4_divert_pop, _m4_defun_epi): Don't expand the word
14110 stored in _m4_divert_diversion or _m4_divert_dump.
14111 (m4_divert_pop): When the parameter is given, compare the symbolic
14112 name with the last diversion pushed on the stack. Previously, the
14113 current diversion was compared with the numeric value of the
14114 diversion given as the parameter.
14115 (m4_require): If the macro hasn't been expanded yet, call ...
14116 (_m4_require_call): this new macro.

14276 * bin/autoscan.in: Open autoscan.log only after ``parse_args'';

14281 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Remove

14336 (autoconf, autoheader, autom4te, autoreconf, autoscan, autoupdate,

14397 * lib/mdate-sh: Don't use "set - x`$ls_command /`", as zsh mishandles
14398 the spaces inside $ls_command. Problem reported by Loulou Pouchet in
14399 <http://lists.gnu.org/archive/html/autoconf/2004-12/msg00074.html>.
14400 Don't use "set - x"; plain "set x" is enough, and simplifies debugging.

14423 * lib/autoconf/functions.m4 (AC_FUNC_MEMCMP): Use
14424 "char c = '\200';" rather than "char c = 0x80;" as the
14425 latter doesn't conform to the strict C standard due to
14426 overflow on signed char hosts.
14428 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Prefer -qlanglvl=extc89
14429 to -qlanglvl=ansi. We don't want to disable extensions.

14542 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): If xmkmf returns
14543 "/usr/include", clear ac_x_includes instead of leaving it as "no"
14544 (trivial change). Problem and patch reported by Andrew Church in:
14545 http://lists.gnu.org/archive/html/bug-autoconf/2004-04/msg00016.html
14547 2004-09-03 Paul Eggert <eggert@cs.ucla.edu>

14611 This isn't a complete fix but it's an improvement.
14613 * bin/autoconf.as (autom4te_options): New var.
14614 Use it instead of appending to AUTOM4TE, so that we can allow
14615 spaces in the build directory's absolute name.
14616 * bin/autoheader.in ($autoconf): Allow spaces in file names.
14617 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP, _AT_CHECK,

14631 and isnan. From a suggestion by Kevin Ryde.
14633 * lib/Autom4te/General.pm (END): Return correct exit status even

14638 * tests/torture.at (Deep Package): Use configure.in, not configure.ac,
14639 for compatibility with Automake 1.4. Reported by J C Fitzgerald in
14640 <http://lists.gnu.org/archive/html/bug-autoconf/2003-08/msg00051.html>.

14651 2004-08-02 Alexandre Duret-Lutz <adl@gnu.org>
14653 * lib/autom4te.in (Automake-preselections): Preselect
14654 AC_CANONICAL_BUILD and AC_CANONICAL_TARGET. Automake 1.9.1 will

14666 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): Use "set -o posix"
14667 with pdksh, too. Problem reported by Patrick Welche via
14669 * doc/autoconf.texi (Shellology): Note that set -o posix is
14670 useful for pkdsh, too.
14672 2004-06-24 Paul Eggert <eggert@cs.ucla.edu>
14674 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Require
14675 _AS_UNSET_PREPARE, so that we can use $as_unset directly.
14676 Don't fail if ENV or BASH_ENV is readonly.
14677 (AS_SHELL_SANITIZE): Don't fail if ENV, MAIL, MAILPATH, LC_ALL,

14688 * doc/autoconf.texi (File System Conventions): Warn about
14689 names like "aux". Problem reported by Eric Blake.
14691 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY (C)): Use division
14692 by zero instead of array size, so that we can use any arithmetic
14693 constant expression (instead of requiring an integer constant
14694 expression). This allows us to test expressions like DBL_MAX <
14695 LDBL_MAX, which didn't conform to the C standard using the old
14697 (AC_C_LONG_DOUBLE): Put back in the tests for LDBL_MAX and LDBL_EPSILON,
14698 now that we can do floating-point tests at compile time.
14700 2004-06-02 Paul Eggert <eggert@cs.ucla.edu>
14702 * lib/autoconf/c.m4 (AC_C_LONG_DOUBLE): Don't check LDBL_MAX
14703 and LDBL_EPSILON, as the resulting expression isn't an
14704 integer constant expression and violates the C standard.
14705 Problem reported by Nelson H. F. Beebe. Also, check
14706 for "L" suffix, and check that long double doesn't have
14707 worse range or precision than double, that mixed-mode
14708 arithmetic doesn't generate a diagnostic, that double
14709 constants fit in long double.
14711 2004-06-03 Kevin Ryde <user42@zip.com.au>
14713 * doc/autoconf.texi (Function Portability): Add notes on free(NULL),
14714 malloc(0) and realloc(NULL,size).
14716 * doc/autoconf.texi (Shell Substitutions): Spelling error reported by
14719 2004-05-31 Paul Eggert <eggert@cs.ucla.edu>
14721 * lib/autoconf/headers.m4 (HAVE_STDBOOL_H): Detect _Bool bug
14722 in HP aC++/ANSI C B3910B A.05.55 [Dec 04 2003]. Problem reported
14725 2004-05-26 Paul Eggert <eggert@cs.ucla.edu>
14727 * doc/autoconf.texi (Limitations of Builtins): Mention that ! COMMAND
14728 can be rewritten using if-then-else. Suggested by Bruno Haible.
14730 2004-05-25 Paul Eggert <eggert@cs.ucla.edu>
14732 * doc/autoconf.texi (testsuite Scripts): Fix typo.
14733 Problem reported by Stepan Kasal.
14735 2004-05-24 Paul Eggert <eggert@cs.ucla.edu>
14737 * tests/Makefile.am (autoconfdir): Fix to match comment (trivial
14738 change). Patch reported by Ralf Wildenhues in
14739 <http://mail.gnu.org/archive/html/bug-autoconf/2004-05/msg00092.html>.
14741 * lib/autoconf/functions.m4 (AC_FUNC_MBRTOWC): Don't assume that a
14742 function F exists if the compiler and linker let you compile an
14743 expression like (F != 0). Recent versions of GCC optimize away
14744 the reference to F in that case, since every function address must
14745 be nonzero, so the link succeeds even if F does not exist.
14746 Problem reported by Manu in
14747 <http://mail.gnu.org/archive/html/bug-gnu-utils/2004-05/msg00060.html>.
14749 * doc/autoconf.texi (Systemology): Standardize on the spelling of
14750 "Unix". Many uses changed.
14751 (Limitations of Builtins): Explain better why the ! command isn't
14754 2004-05-22 Alexandre Duret-Lutz <adl@gnu.org>
14756 * lib/autom4te.in (Automake-preselections): Preselect
14757 LT_SUPPORTED_TAG in lieu of AC_LIBTOOL_TAGS.

14761 * doc/autoconf.texi (Function Portability): Add strerror_r, cross
14762 referencing AC_FUNC_STRERROR_R.
14764 * doc/autoconf.texi (Particular Functions): In AC_FUNC_CLOSEDIR_VOID,
14765 note pessimistic assumption when cross compiling.
14767 2004-05-16 Paul Eggert <eggert@cs.ucla.edu>
14769 * doc/autoconf.texi (Limitations of Make): Note that BSD make
14770 (until 2004) invoked subcommands with sh -e, contra POSIX.
14771 Reported by Kevin Ryde.
14773 2004-05-10 Eric Sunshine <sunshine@sunshineco.com>
14775 * programs.m4 (_AC_PROG_GREP): Fixed bug where PATH argument handed to
14776 _AC_PATH_PROG_FEATURE_CHECK contained leading whitespace (i.e.
14777 " $PATH:/usr/xpg4/bin"). This resulted in bogus tests, such as
14778 `test -f " /usr/bin/grep"', which _always_ failed.
14779 (AC_PROG_SED): Ditto bogus PATH fix.
14780 * autoconf.texi (AC_PROG_GREP): Properly document that this macro
14781 requires that grep correctly supports _multiple_ `-e' options, rather
14782 than stating only that grep should accept `-e'.
14784 2004-05-03 Paul Eggert <eggert@cs.ucla.edu>
14786 Port to C99, which requires that 'exit' be declared.
14788 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Use AC_INCLUDES_DEFAULT
14789 to ensure that stdlib.h is included.
14790 * lib/autoconf/functions.m4 (_AC_LIBOBJ_ALLOCA, AC_FUNC_SETPGRP,
14791 AC_FUNC_STRTOD, AC_FUNC_SETVBUF_REVERSED, AC_FUNC_FORK, _AC_FUNC_FORK,
14792 _AC_FUNC_VFORK, AC_FUNC_WAIT3): Likewise.
14793 * lib/autoconf/specific.m4 (AC_SYS_RESTARTABLE_SYSCALLS): Likewise.
14794 * lib/autoconf/types.m4 (AC_TYPE_GETGROUPS): Likewise.
14795 * lib/autoconf/headers.m4 (AC_HEADER_STDC): Include <stdlib.h>
14796 when using 'exit' in a test; C99 requires that 'exit' be declared.
14798 2004-05-02 Paul Eggert <eggert@cs.ucla.edu>
14800 * doc/autoconf.texi (Particular Programs): AC_PROG_GREP
14801 now prefers 'grep' implementations that accept -e.
14802 (Limitations of Usual Tools): Describe problems of traditional
14803 egrep and fgrep with long input lines, and of traditional grep
14805 * lib/autoconf/programs.m4 (AC_PROG_GREP): Check for -e, too.
14806 (_AC_PROG_GREP): Assume 3rd arg is properly quoted for the shell.
14807 All callers changed. Append /usr/xpg4/bin to the PATH, for
14809 (_AC_FEATURE_CHECK_LENGTH): Discard stderr, so we don't bother
14810 the user with complaints about multiple -e options.
14811 * tests/local.at (AC_STATE_SAVE): Use $GREP, not grep.
14812 Define it with AC_PROG_GREP.
14813 * configure.ac (AC_PROG_GREP): Add.
14814 * lib/freeze.mk (GREP): New macro.
14816 2004-05-02 Eric Sunshine <sunshine@sunshineco.com>
14818 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Consult $SHELL as
14819 a possible candidate only after all others fail, rather than
14820 consulting it first. This improves backward compatibility by
14821 better reflecting the way shell selection occurred in previous
14822 versions of Autoconf, and should help to avoid triggering latent
14823 problems in other packages, such as the one in Automake where zsh
14824 is not handled robustly:
14825 http://mail.gnu.org/archive/html/automake/2004-04/msg00095.html
14826 Although it is not Autoconf's responsibility to work around
14827 problems in Automake, it nevertheless makes sense to avoid
14828 introducing unnecessary incompatibilites.
14830 2004-04-22 Albert Chin-A-Young <china@thewrittenword.com>,
14831 Gary V. Vaughan <gary@gnu.org>
14833 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Don't guess
14834 how deeply nested we are when a suitable tool is found, set the
14835 ac_path_TOOL_found flag.
14836 (_AC_PATH_PROG_FEATURE_CHECK): Encapsulate knowledge of how deeply
14837 nested we are in this macro. Break out of all 3 nested loops if
14838 ac_path_TOOL_found is set.
14840 2004-04-21 Gary V. Vaughan <gary@gnu.org>
14842 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Break out
14843 of the _AS_PATH_WALK loop too if GNU flavor is found.
14845 2004-04-21 Alexandre Duret-Lutz <adl@gnu.org>
14847 * doc/autoconf.texi (Limitations of Make): Update documentation
14848 for `$<'. New entry `Long lines', based on a report from Simon
14849 Josefsson. Augment the documentation for SHELL = @SHELL@ with a
14850 paragraph about DJGPP, based on a mail from Richard Dawe.
14852 2004-04-20 Paul Eggert <eggert@twinsun.com>
14854 * tests/c.at (C keywords): Don't assume that GCC supports
14855 "restrict" and "inline", as sufficiently-old GCC versions do not
14856 (also, GCC configured to be in pedantic C89 mode does not).
14857 Problem reported by Sumit Pandya in:
14858 http://mail.gnu.org/archive/html/autoconf/2004-04/msg00092.html
14860 * lib/autoconf/c.m4 (_AC_PROG_CC_G, _AC_PROG_CXX_G): Don't
14861 consider -g to work if it generates warnings when plain compiles
14862 don't. Problem reported by Braden McDaniel in:
14863 http://mail.gnu.org/archive/html/autoconf-patches/2003-07/msg00014.html
14865 * doc/autoconf.texi (Slashes): New section, to document a problem
14866 reported by Jim Meyering in:
14867 http://mail.gnu.org/archive/html/bug-coreutils/2004-02/msg00060.html
14869 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Remove potential
14870 linker output files before linking, to work around IRIX 6 linker bug.
14871 Problem reported by Rainer Orth in:
14872 http://mail.gnu.org/archive/html/autoconf-patches/2004-02/msg00007.html
14874 2004-04-20 Gary V. Vaughan <gary@gnu.org>
14876 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Make the
14877 best tool so far counter rely on the tool path variable name to
14878 avoid checks for one tool being affected by the results of running
14879 the length check on a previous tool.
14881 * lib/autoconf/programs.m4 (_AC_PROG_GREP): Take an additional
14882 match expression argument, as different greps have different
14883 regular expression flavours.
14884 (AC_PROG_FGREP): Pass 'FGREP'. fgrep treats all match chars as
14886 (AC_PROG_EGREP): Pass 'EGREP$'.
14887 (AC_PROG_GREP): Pass 'GREP$'.
14889 2004-04-20 Albert Chin-A-Young <china@thewrittenword.com>
14891 * lib/autoconf/programs.m4 (AC_PROG_GREP): Cache variable
14892 is `ac_cv_path_GREP', not `oc_cv_path_GREP'.
14894 2004-03-29 Paul Eggert <eggert@twinsun.com>
14896 * doc/autoconf.texi (Particular Headers, Particular Types, Generic
14897 Types, Specific Compiler Characteristics, System Services,
14898 Obsolete Macros): Use 'long int', 'short int', 'unsigned int'
14899 etc. consistently instead of 'long', 'short', 'unsigned' etc.
14900 * lib/autoconf/c.m4 (AC_LANG_INT_SAVE(C), AC_C_BIGENDIAN): Likewise.

14914 * doc/autoconf.texi (Particular Structures): AC_STRUCT_TIMEZONE
14915 now defines HAVE_DECL_TZNAME if it is declared, when
14916 HAVE_STRUCT_TM_TM_ZONE is not defined.
14917 * lib/autoconf/types.m4 (AC_STRUCT_TIMEZONE): Implement this.
14918 Do not assume atoi. Rely on HAVE_DECL_TZNAME when testing

14923 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Corrected
14924 superfluous backslashing of quotes (") in sed expressions;
14925 thanks to Paul Eggert.

14985 2004-03-03 Paul Eggert <eggert@twinsun.com>
14987 * bin/Makefile.am (edit): Don't use $< in a context where
14988 POSIX doesn't require support for it. Use $@.in instead.
14989 Problem reported by Anthony N. Frasso in

15149 * doc/autoconf.texi (Default Includes): Include <stdint.h> even if
15150 HAVE_INTTYPES_H is defined. This is needed on Tru64 5.1b with
15151 Compac C V6.5-207 (dtk), which defines uintmax_t in <stdint.h> but
15152 not <inttypes.h>. Problem reported by Tim Mooney in
15153 <http://mail.gnu.org/archive/html/bug-coreutils/2004-01/msg00147.html>.
15154 * lib/autoconf/headers.m4 (_AC_INCLUDES_DEFAULT_REQUIREMENTS):
15157 * lib/autoconf/programs.m4 (AC_PROG_SED): Use diff, not sed;
15158 otherwise "make check" fails because it forbids cmp (I guess
15159 because cmp treats files as binary on DOS-like systems).
15161 * tests/mktests.sh: Update copyright date to 2004, since some tests
15162 have changed in 2004.
15164 2004-01-23 Gary V. Vaughan <gary@gnu.org>
15166 * lib/autoconf/programs.m4 (AC_PROG_SED): New macro to test for a
15167 non-truncating sed or gsed program in PATH.
15168 * tests/acprograms.at: Add it.
15169 * doc/autoconf.texi (Particular Programs): Document it.
15172 2004-01-15 Paul Eggert <eggert@twinsun.com>
15174 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Try -std, not -std1, since
15175 -std1 disables some useful extensions on Tru64. Problem reported
15176 by N. Lichtmaier in
15177 <http://mail.gnu.org/archive/html/autoconf/2004-01/msg00100.html>.
15179 2004-01-14 Paul Eggert <eggert@twinsun.com>
15181 * doc/autoconf.texi (Programming in M4sh): Document that
15182 AS_MKDIR_P succeeds if the destination is a symbolic link
15183 to an existing directory.
15184 (Limitations of Usual Tools): Note that mkdir -p might not
15185 succeed on symlinks to directories.
15187 2004-01-13 Paul Hilfinger <hilfinger@CS.Berkeley.EDU>
15189 * lib/autoconf/autoupdate.m4 (AU_DEFUN): Grammar fix in comment.
15190 * bin/autoheader.in: Grammar fix in message.
15191 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P):
15192 Test for dir before calling mkdir -p. (trivial changes)
15194 2004-01-13 Eric Blake <ebb9@byu.net>
15196 * doc/autoconf.texi (Obsolete Macros): In AC_TRY_COMPILE and
15197 AC_TRY_LINK, s/AC_LANG_SOURCE/AC_LANG_PROGRAM/. (trivial change)
15199 2004-01-10 Jim Meyering <jim@meyering.net>
15201 * doc/autoconf.texi (Running the Preprocessor): Correct grammar.
15203 2004-01-09 Paul Eggert <eggert@twinsun.com>
15205 * lib/autoconf/general.m4: Fix bug: AC_CHECK_SIZEOF evokes a warning
15206 with `autoconf -Wall,error'. Bug reported by Eric Blake in:
15207 http://mail.gnu.org/archive/html/autoconf-patches/2004-01/msg00000.html
15208 (_AC_COMPUTE_INT_COMPILE): Invoke _AC_COMPILE_IFELSE, not
15209 AC_COMPILE_IFELSE, since we now assume our caller invokes
15210 AC_LANG_COMPILER_REQUIRE, for symmetry with _AC_COMPUTE_INT_RUN.
15211 (_AC_COMPUTE_INT_RUN): Likewise, for _AC_RUN_IFELSE instead
15212 of AC_RUN_IFELSE; this avoids the warning mentioned above.
15213 (_AC_COMPUTE_INT): Invoke AC_LANG_COMPILER_REQUIRE.
15215 2004-01-07 Paul Eggert <eggert@twinsun.com>
15217 * lib/autoconf/general.m4 (_AC_LIBOBJS_NORMALIZE): Avoid \$ inside
15218 `"'...'"`, as it's confusing (and I suspect it may not work on
15219 some platforms). The code was incorrect anyway, as it assumed
15220 that \$ evaluated to itself in that context. Reported by
15221 Alexandre Duret-Lutz.
15223 2004-01-07 Alexandre Duret-Lutz <adl@gnu.org>
15225 * lib/autom4te.in (Automake-preselections): Preselect AC_LIBTOOL_TAGS
15226 and _LT_AC_TAGCONFIG.
15228 2004-01-06 Paul Eggert <eggert@twinsun.com>
15230 * doc/autoconf.texi (One Macro Call): Fix an incorrect
15231 example, and add more examples. Reported by Eric Sunshine.
15233 2004-01-05 Paul Eggert <eggert@twinsun.com>
15235 * doc/autoconf.texi (Limitations of Usual Tools):
15236 Remove warning against "rm -fr" introduced yesterday; it
15239 * bin/Makefile.am (autoconf, autoheader, autom4te, autoreconf,
15240 autoscan, autoupdate, ifnames): Don't use chmod -w.
15241 * lib/Makefile.am (autom4te.cfg): Likewise.
15242 * doc/autoconf.texi (Limitations of Usual Tools): Warn against

15249 by doing lineno substitution only on lines containing "$LINENO".
15251 2004-01-04 Paul Eggert <eggert@twinsun.com>
15253 * lib/autoconf/general.m4 (AC_ARG_PROGRAM):
15254 Use "rm -f" to remove conftest.sed, not plain "rm".
15255 Bug reported by David Relson in
15256 <http://mail.gnu.org/archive/html/autoconf/2004-01/msg00011.html>.
15258 * Makefile.am (autom4te-update):
15259 Replace "rm -rf" and "rm -fr" with "rm -f -r", as POSIX requires.
15260 * Makefile.maint (my-distcheck, do-po-update): Likewise.
15261 * doc/autoconf.texi (Guidelines): Likewise.
15262 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Likewise.
15263 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): Likewise.

15266 * lib/m4sugar/m4sh.m4 (AS_TMPDIR): Likewise.
15267 * tests/Makefile.am (clean-local): Likewise.
15268 * tests/tortue.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS,
15270 * doc/autoconf.texi (Limitations of Usual Tools):
15271 Warn against "rm -fr".
15273 2004-01-03 Paul Eggert <eggert@twinsun.com>
15275 * doc/autoconf.texi (Limitations of Usual Tools): Mention that cc
15276 -c -o might not work. From a suggestion by Kevin Ryde.
15277 (C Compiler, Generating Sources, Limitations
15278 of Usual Tools, Limitations of Make, Making testsuite Scripts):
15279 Don't put '-o' after non-options, as POSIX doesn't allow this.
15280 Mention that cc's name might be gcc or c89 or whatever.
15282 2004-01-04 Kevin Ryde <user42@zip.com.au>
15284 * doc/autoconf.texi: Add various further index entries.
15286 2003-12-29 Paul Eggert <eggert@twinsun.com>
15288 * bin/autoreconf.in (autoreconf_current_directory):
15289 Fix typo: mkdir without umask arg.
15291 2003-12-27 Alexandre Duret-Lutz <adl@gnu.org>
15293 * doc/autoconf.texi (Limitations of Make) <Automatic rule rewriting>:
15294 Documents OSF1/Tru64 make behavior. Replace `VPATH = ../src' by
15295 `VPATH = ../pkg/src' in examples to make the OSF1/Tru64 make
15296 explanation clearer.
15298 2003-12-24 Andreas Schwab <schwab@suse.de>
15300 * doc/autoconf.texi (Default Includes): Fix misspelling of

15305 * configure.ac: Test if sh -n works.
15306 * configure: Regenerate.
15307 * tests/atlocal.in: Store the result here.
15308 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Extracted from

15310 of explicitly testing.
15311 (AT_CHECK_PERL_SYNTAX): Moved from tools.at.
15312 (AT_CHECK_AUTOCONF): Test for the configure script syntax.
15313 * tests/tools.at (Syntax of the shell scripts): Simplify

15316 AT_CHECK_PERL_SYNTAX.

15329 (_AS_SHELL_FN_WORK, AS_INIT_WITH_SHELL_FN): New
15331 (AS_SHELL_SANITIZE): Move reinvocation code from
15332 _AS_LINENO_WORKS, use it to find out if shell
15334 (_AS_LINENO_WORKS): Don't find another shell if $LINENO

15398 * doc/autoconf.texi (Using System Type): Revise, showing $host rather
15399 than $target since the latter is not usual, add guidelines on when to
15400 use or not use the system type.

15404 * doc/autoconf.texi (Limitations of Usual Tools): Fix what looks like a

15424 * lib/autoconf/status.m4 (_AC_SRCPATHS): Fix use of AS_SET_CATFILE

15581 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Omit quoted
15582 -mGLOB_options_string stuff for Intel ifc, which can cause
15583 _AC_FC_LIBRARY_LDFLAGS to fail. Use (faster) case for
15584 pattern-matching instead of grep.

15606 * lib/autoconf/fortran.m4 (_AC_PROG_FC_G): Use language-specific
15607 cache variable instead of $G77 to decide whether to include -O2,
15608 since $G77 is specific to Fortran 77.
15610 2003-10-03 Steven G. Johnson <stevenj@alum.mit.edu>
15612 * lib/autoconf/fortran.m4 (AC_FC_FREEFORM): Support Absoft "-f

15618 arguments so that it can be used with syntax identical to
15619 AC_PROG_F77, and so that we can more easily decide to
15620 remove/deprecate the DIALECT optional argument in the future if it
15621 proves troublesome.
15622 (AC_FC_FREEFORM): Exit 77 upon failure to fix test suite for
15623 non-freeform-supporting compilers. Document freeform flags.
15625 2003-10-03 Akim Demaille <akim@epita.fr>
15627 * configure.ac: Look for emacs, not macs.

15630 2003-10-03 Akim Demaille <akim@epita.fr>
15632 * lib/autom4te.in (Autoreconf-preselections): Trace AC_CONFIG_AUX_DIR.
15633 * bin/autoreconf.in (autoreconf_current_directory): Create the
15634 AUX_DIR if needed, for sake of automake --add-missing etc.
15635 Suggested by Alexandre Duret-Lutz.
15637 2003-10-03 Akim Demaille <akim@epita.fr>
15639 * configure.ac: Quotation and formatting changes.

15686 Problem reported by Lars J. Aas in
15687 <http://mail.gnu.org/archive/html/autoconf/2003-07/msg00042.html>.
15688 (_AS_MKDIR_P_PREPARE): Change "rm -fr ./-p" to the more-conservative
15689 "test -d ./-p && rmdir ./-p". Suggested by Andreas Schwab in:
15690 http://mail.gnu.org/archive/html/autoconf-patches/2003-09/msg00039.html
15692 2003-09-26 Akim Demaille <akim@epita.fr>
15694 * lib/autoconf/status.m4 (_AC_OUTPUT_COMMANDS): Make sure the
15695 directory for AC_CONFIG_COMMANDS' first argument exists.
15696 This makes valid the invocation of _AC_SRCPATH that follows.
15697 Reported by Eric Sunshine.
15698 * doc/autoconf.texi (Configuration Commands): Adjust.
15700 2003-09-26 Akim Demaille <akim@epita.fr>

15721 The test suite are sometimes assigning timings incorrectly.
15722 Reported by Henk Krus.
15723 Diagnosed by Nicolas Joly.
15725 * lib/autotest/general.m4 (AT_CLEANUP): Rename AT_help as
15727 Instead of making AT_help a sequence of assignments to grow
15728 $at_help_all, just make AT_help_all be the growing contents of
15729 $at_help_all, and make a single assignment in...
15731 (at_times_skip): Flip the meaning and rename as...
15732 (at_times_p): this.
15733 (AT_INIT): When summarizing the test that ran, remove

15741 * bin/Makefile.am (edit): Handle '@configure_input@'.
15742 (autoconf, autoheader, autom4te, autoreconf, autoscan, autoupdate)
15743 (ifnames): chmod -w.
15744 * tests/wrapper.as (AUTOCONF, AUTOM4TE, ): Point to tests/
15745 executables, not bin/ executables! Otherwise all the magic needed
15746 to find non installed files is turned off. This caused a failure
15747 of test 40 and 41 that ran aclocal 1.8 which in turn ran autom4te
15748 as found in its environment (sent by tests/autoreconf): pointing
15749 to bin/autom4te that could not find its files.
15750 * tests/mktests.sh: Force the replacement of generated files, for
15751 the sake of "mv" program that are interactive when overwriting a
15753 * config/install-sh: Upgrade from CVS Automake.
15755 2003-09-23 Paul Eggert <eggert@twinsun.com>

15760 2003-09-23 Daniel Jacobowitz <drow@mvista.com> and
15761 Paul Eggert <eggert@twinsun.com>
15763 Trivial change to support GCC's configuration procedure.

15842 2003-09-04 Akim Demaille <akim@epita.fr>
15844 * tests/mktests.sh (ac_exclude_list): Add AC_FC_FUNC.
15846 2003-09-02 Steven G. Johnson <stevenj@alum.mit.edu>
15848 Add support for newer Fortran dialects. The F77 interface is
15849 unchanged, and continues to support Fortran 77. New FC macros
15850 correspond to all the old F77 macros, with output variables FC,
15851 FCFLAGS, and FCLIBS. AC_PROG_FC defaults to picking the newest
15852 available dialect, but older dialects can be specified. There are
15853 new macros AC_FC_SRCEXT to set the source extension, and
15854 AC_FC_FREEFORM to accept free-form source files.
15856 * lib/autoconf/c.m4 (_AC_LANG_PREFIX(C), _AC_LANG_PREFIX(C++)):

15892 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): Don't m4_default the arguments that
15893 are defaulted by AT_CHECK anyway.
15894 Use AT_CHECK_AUTOM4TE.

15977 * bin/autoscan.in: Use Autom4te::ChannelDefs.
15978 * lib/Autom4te/General.pm: Don't export error: you don't own it.
15980 2003-08-21 Akim Demaille <akim@epita.fr>
15982 First stab at preserving warnings between calls to autom4te,
15983 including when the cache is used.
15985 There are still several issues: (i) there are too many runs of m4
15986 (one for include, one for warnings, and some more), (ii) warnings
15987 spreading on several lines are not handled gracefully, (iii) the
15988 code meant to have the call stack display for errors does not work
15989 (its handling should move from m4 to autom4te).
15991 * bin/autom4te.in Autom4te::Channels, Autom4te::ChannelDefs):
15993 (@preselect): Add m4_warn.
15994 ($exit_status): Remove, use $exit_code.
15995 ($help): Use Autom4te::ChannelDefs::usage.
15996 (&handle_m4): No longer define the m4_warnings.
15997 At each run, extract and report the warnings.
15998 Always cache the result, including if the exit status is on
15999 failure, since if nothing changes, we should result in the same
16000 failure, hence we can use the cache.
16001 * lib/m4sugar/m4sugar.m4 (m4_warning_ifelse, _m4_warning_ifelse)
16002 (_m4_warning_error_ifelse, __m4_warning_error_ifelse, _m4_warn):
16004 (m4_warn): Redefine as a do-nothing: it is its invocation that
16005 matters, as warnings are now reported via traces.
16006 * lib/autoconf/general.m4 (AC_DIAGNOSE): Don't make it a copy of
16007 the contents of m4_warn: make it _call_ m4_warn, so that tracing
16008 the latter reveals calls to the former.
16012 * tests/m4sugar.at (m4@&t@_warn): Use existing warning categories.

16041 Reported by Alexandre Duret-Lutz.

16045 * bin/autoupdate.in, bin/autoheader.in, bin/autoreconf.in,
16046 * bin/autom4te: Adjust.
16047 In particular, be Autoconf tools are really silent when properly
16048 working, bind the verbosity of the 'note' channel to $verbose.
16049 * lib/Autom4te/General.pm (&find_file, &mtime, &update_file)
16050 (&xsystem, &contents): Remove, since they are exported by...

16117 * lib/autotest/general.m4 (AT_INIT): Correct typo in final status
16120 2003-08-12 Derek Price <derek@ximbiot.com>
16122 * lib/autotest/general.m4 (AT_CHECK): Use new _AT_CHECK API.
16123 (AT_CHECK_NOESCAPE): Move core functionality to...
16124 (_AT_CHECK): ...this new macro.
16126 2003-08-07 Derek Price <derek@ximbiot.com>
16128 * lib/autotest/general.m4 (AT_CHECK): Move core functionality...
16129 (AT_CHECK_NOESCAPE): ...to this new macro.
16131 2003-07-31 Paul Eggert <eggert@twinsun.com>
16133 * lib/m4sugar/m4sh.m4 (_AS_UNSET_PREPARE): Work around a bug
16134 in Bash 2.01. Problem reported by Brian Gough in
16135 <http://mail.gnu.org/archive/html/bug-autoconf/2003-07/msg00106.html>.
16137 2003-07-25 John W. Eaton <jwe@bevo.che.wisc.edu>
16139 * lib/autoconf/fortran.m4 (AC_F77_LIBRARY_LDFLAGS): Also ignore
16140 -lcrt1.o, for OS X. (trivial change)
16142 2003-07-07 Paul Eggert <eggert@twinsun.com>
16144 * lib/autoconf/c.m4 (AC_C_INLINE): Wrap the '#define inline ...'
16145 inside '#ifndef __cplusplus'. Problem reported by
16148 2003-07-06 Bill Clarke <llib@computer.org>
16150 * lib/autoconf/functions.m4 (AC_FUNC_MMAP): Cast pointer to
16151 'long', not 'int', for benefit of Sun's recent C++ compilers
16152 (trivial change). See:
16153 http://mail.gnu.org/archive/html/autoconf-patches/2003-07/msg00007.html

16159 * lib/Makefile.am (autom4te.cfg): Make it read only.
16160 Depend on Makefile since it contains substitutions.
16161 From Paolo Bonzini.
16162 * lib/autom4te.in (args): Add local.at? for Autotest args.
16163 This change was made on autom4te.cfg which is generated.

16168 * doc/autoconf.texi (Header Portability): sys/mount.h.
16169 From Gareth McCaughan.
16171 2003-06-23 Akim Demaille <akim@epita.fr>
16173 * lib/autotest/general.m4 (AT_INIT): Report a single config.log,
16174 not all of them. This fixes 1. the fact that when testing
16175 Autoconf there are many many config.log, 2. the incorrect use of
16176 top_srcdir to find config.log.
16177 Don't mix the detailed output of failed test with the summary of
16178 failures. Rather, append detailed log afterwards.
16180 2003-06-23 Akim Demaille <akim@epita.fr>
16182 * tests/local.at (AT_CHECK_CONFIGURE): Adjust to the verbose being
16183 always run: output config.log on $at_group_log.
16185 2003-06-23 Akim Demaille <akim@epita.fr>
16187 * tests/torture.at (#define header templates): Don't use quotes in
16188 C++ comments as it puzzles Emacs' sh font-lock-mode.
16190 2003-06-23 Akim Demaille <akim@epita.fr>
16192 * tests/mktests.sh (au_exclude_egrep): Fix output copyright notice.
16193 * lib/autom4te.cfg (args): Add local.at? for Autotest args.
16194 * tests/atspecific.m4: Rename as...

16203 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Extend test program to get an
16204 error from OSF 4.0 Compaq cc in its default almost-ANSI mode, thereby
16205 ensuring we add -std1 for full-ANSI.
16207 * doc/autoconf.texi (hdrindex): New macro.
16208 Add index entries for portability of various standard header files.
16210 2003-06-20 Akim Demaille <akim@epita.fr>

16237 * lib/autotest/general.m4 (AT_XFAIL_IF): New macro.
16238 (TEST_SCRIPT): New diversion.

16240 (AT_CLEANUP): ...to here. Undivert TEST_SCRIPT.
16241 (AT_INIT): Support for expected failures.
16243 2003-06-02 Akim Demaille <akim@epita.fr>
16245 * bin/autom4te.in, bin/autoscan.in, bin/autoheader.in: White space

16248 Autoconf nor Automake.
16249 (&contents): New, from Automake.
16252 2003-05-28 Paul Eggert <eggert@twinsun.com>
16254 * NEWS, doc/autoconf.texi (Particular Functions),

16260 * lib/Autom4te/General.pm (END): Print diagnostics to STDERR.
16261 (handle_exec_errors): New function. Work around $! being
16262 altered by WEXITSTATUS.
16263 (xqx, xsystem): Use handle_exec_errors.
16265 2003-05-23 Alexandre Duret-Lutz <adl@gnu.org>
16267 * lib/Autom4te/General.pm (END): Rewrite exit code processing.
16268 Do not call `_exit()', simply modify `$?'.
16269 (xsystem): Reset $! before running system, and check it afterward.
16270 * tests/tools.at (autoupdating AC_PREREQ): Expect exit status
16271 63 for version mismatches.
16273 2003-05-23 Akim Demaille <akim@epita.fr>
16275 * lib/autoconf/status.m4: Prefer "TAB-SP" to "SP-TAB", because of
16276 Emacs' dangerous whitespace.el behavior (smashing "useless" spaces in
16277 the middle of a line).
16278 * lib/m4sugar/m4sugar.m4: Likewise.
16279 Remove useless spaces in comments.
16281 2003-05-23 Akim Demaille <akim@epita.fr>
16283 * lib/m4sugar/m4sugar.m4 (m4_version_prereq): Failure causes an
16284 exit 63, so that we (or Automake's "missing") can tell the
16285 difference with a plain failure.
16286 * doc/autoconf.texi (Notices): Adjust.
16288 2003-05-23 Akim Demaille <akim@epita.fr>
16290 * Makefile.am, bin/Makefile.am, config/Makefile.am,
16291 * doc/Makefile.am, lib/autoconf/Makefile.am, tests/Makefile.am:
16292 White spaces cleanup.
16294 2003-05-22 Jim Meyering <jim@meyering.net>
16295 Paul Eggert <eggert@twinsun.com>
16297 * lib/autoconf/c.m4 (_AC_PROG_CXX_EXIT_DECLARATION):
16298 Remove `#include <stdlib.h>' from the list; we should never
16299 make confdefs.h include <stdlib.h> or <cstdlib>, because the
16300 resulting namespace pollution would cause other tests to fail.
16301 Configure scripts run with some older versions of g++ and HP's
16302 aCC would fail due to such an #include. Problems reported by
16303 Matthew Mueller in <http://bugs.debian.org/120704> and by
16305 <http://mail.gnu.org/archive/html/autoconf/2003-05/msg00063.html>.
16306 In the test, use the test declaration before including <stdlib.h>,
16307 as that's closer to how it'll be used.
16309 2003-05-23 Akim Demaille <akim@epita.fr>
16311 * doc/autoconf.texi (Header Portability): ucred.h.
16314 2003-05-22 Paolo Bonzini <bonzini@gnu.org>
16316 Overhaul Autotest's logging: generate separate log files
16317 in testsuite.dir/NNN/testsuite.log, and append them to
16318 testsuite.log instead of re-running the test verbosely.
16320 * lib/autotest/general.m4 (AT_INIT): Use a single redirected
16321 file descriptor, write 0 to at_status_file instead of setting
16322 at_status=0, initialize some new variables (at_status_file,
16323 at_group_log, at_suite_log, at_tee_pipe). Remove the cruft
16324 to rerun the tests, instead append the at_group_log to the
16325 at_suite_log when a test fails.
16326 (AT_SETUP): pipe the test case's output into at_tee_pipe,
16327 with the AS_MESSAGE_LOG_FD redirected to stdout.
16328 (AT_CLEANUP): save the output status in $at_status_file
16329 and restore it, redirect the AS_MESSAGE_LOG_FD back to
16330 its original place.
16331 (AT_CHECK): since tests are run with a redirected stdout,
16332 and used to be re-run in verbose mode, turn some $at_verbose
16333 into echo, and don't redirect the output of testing stdout
16336 * lib/autotest/autoconf.texi (testsuite Scripts): Update
16337 the name of the debugging directory and information about

16457 2003-05-06 Akim Demaille <akim@epita.fr>
16459 Don't try to be smart with aclocal 1.8+ because (i) aclocal no
16460 longer updates aclocal.m4 if useless, (ii) if a file m4_included
16461 by aclocal.m4 is changed it might require the importing of another
16462 m4 extension file, i.e., aclocal must be run.
16464 * bin/autoreconf.in (&run_aclocal, $aclocal_supports_force): New.
16465 (&parse_args): Use --force with aclocal if required and supported.

16479 2003-04-29 Derek Price <derek@ximbiot.com>
16481 * lib/autotest/general.m4 (AT_KEYWORDS): Don't use a comma as the
16482 seperator with m4_append_uniq(). It doesn't work.
16483 (AT_CLEANUP): Add `;' to end of at_help_all.
16484 (AT_INIT): Allow --keywords to be specified more than once. When
16485 grepping $at_help_all for keywords, use the field and keyword
16486 seperators to ensure a complete keyword match. Alter at_prev handling
16487 to support the new --keywords behavior.
16489 2003-04-27 Karl Berry <karl@freefriends.org>
16491 * doc/autoconf.texi: Make the dir entries in the autoconf manual
16492 align better with others. I also made some of the individual
16493 entries on one line, for brevity and to make it easier for me to
16494 sort my dir-example file in the Texinfo distribution :).

16560 reading the section "Present But Cannot Be Compiled" when the
16561 header causes problems.

16565 * tests/torture.at (Configuring subdirectories): Require aclocal
16566 1.4, otherwise the test fails, as it does support configure.ac.
16567 This fixes the "test 40 failed" bug reports.

16657 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Translate colons,
16658 to cope with DOS-style absolute paths, when constructing
16661 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS, _AC_OUTPUT_FILES):
16662 When constructing paths with IFS=:, quote the path. If we're
16663 constructing a DOS-style absolute path, we don't want to split it
16666 * tests/atspecific.m4 (AT_CHECK_CONFIGURE): Fix typo

16686 * doc/autoconf.texi (Limitations of Builtins): Add notes on printf
16687 format starting with "-".
16689 2003-02-20 Alexandre Duret-Lutz <adl@gnu.org>
16691 * doc/autoconf.texi (Limitations of Make): `foo=bar make -e'
16692 is not portable inside Makefile.
16694 2003-02-20 Akim Demaille <akim@epita.fr>
16696 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): When

16714 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Define $1 to an
16715 innocuous variant befor including <limits.h> or <assert.h>. This
16716 works around a bug reported by Albert Chin: HP-UX 11i
16717 (and earlier versions) have a <limits.h> that declares
16718 gettimeofday and many other functions.
16720 2002-12-03 Paul Eggert <eggert@twinsun.com>
16724 * NEWS, configure.ac: Update version.
16726 * doc/fdl.texi: Upgrade to FDL version 1.2.
16728 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Use the function f
16729 nontrivially in main's body, so that f's external declaration is
16730 not optimized away in AIX. This should fix the bug reported by
16732 <http://mail.gnu.org/pipermail/autoconf/2002-November/014508.html>.
16734 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C),
16735 _AC_PROG_PREPROC_WORKS_IFELSE): Use <limits.h> if __STDC__ is
16736 defined, to support freestanding compilers. This should fix the
16737 bug reported by Momchil Velkov in
16738 <http://mail.gnu.org/pipermail/autoconf/2002-November/014490.html>.
16740 * doc/autoconf.texi (Obsolete Macros): Fix typos (insert empty
16741 arg, AC_DEFINE -> AC_DEFINE_UNQUOTED) in documentation for

16772 Update from masters.
16774 2002-11-14 Akim Demaille <akim@epita.fr>
16776 * Makefile.maint: Sync with Bison, i.e.:
16777 (po-check): Scan .l and .y files instead of the
16778 .c and the .h files that they generate. This fixes the bug
16779 reported by Tim Van Holder in:
16780 <http://mail.gnu.org/pipermail/bison-patches/2002-November/001352.html>
16781 Look for N_ as well as for _. Try to avoid matching #define for
16785 2002-11-14 Akim Demaille <akim@epita.fr>
16787 * doc/autoconf.texi (C Compiler): Compiling several files at once.
16788 From Paul Eggert and Albert Chin-A-Young.
16790 2002-11-14 Akim Demaille <akim@epita.fr>
16792 * doc/autoconf.texi (C Compiler): Solitary backslashes.
16793 From Paul Eggert and Albert Chin-A-Young.

16797 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Initialize f=$1 rather
16798 than assigning in main, to avoid HP cc +O3 optimizing it away.
16800 2002-11-12 Peter Eisentraut <peter_e@gmx.net>
16802 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Add -q
16803 option. Process --recheck after parsing all options. Pass -q
16804 option to configure on --recheck.
16805 (AC_OUTPUT): Pass -q from configure to config.status.
16806 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Strip -q from
16807 arguments to record.
16808 * doc/autoconf.texi (config.status Invocation): Document
16809 config.status -q option.
16811 2002-11-07 Alexandre Duret-Lutz <adl@gnu.org>
16813 * bin/autoscan.in (scan_file): Scan Makefile.am too. Ignore
16814 Makefile.in if Makefile.am exists.
16815 (output): Strip `.am' from Makefiles. Don't
16816 output AC_CONFIG_FILES if no Makefiles were found.

16836 Reported by Ezra Peisach.
16838 2002-11-05 Akim Demaille <akim@epita.fr>
16840 * lib/autoconf/autoheader.m4 (_AH_TEMPLATE_OLD, _AH_VERBATIM_OLD):
16842 We _have_ to stop using the old compatibility scheme that tried to
16843 avoid useless backslashes because Libtool 1.4.3 contains a
16844 AC_DEFINE([error_t], [int],
16845 [Define to a type to use for \`error_t' if it is not
16846 otherwise available.])
16847 We _have_ to quote the single quote and backslashes with \. The
16848 old compatibility scheme saw that ` was backslashed, and therefore
16849 did not quote the single quote. Hence before this patch, Autoconf
16850 was not compatible with Libtool.
16852 2002-11-04 Paul Eggert <eggert@twinsun.com>
16854 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Set the following variables,

16872 ($help, $make, &parse_args, &autoreconf_current_directory):
16874 * doc/autoconf.texi (autoreconf Invocation): Adjust.
16876 2002-10-31 Bruno Haible <bruno@clisp.org>

16894 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Use and display
16895 `$(MAKE)' instead of '${MAKE}' to emphasize that we refer to the
16896 Make variable, not a shell variable.
16897 Suggested by Bruno Haible.
16899 2002-10-31 Akim Demaille <akim@epita.fr>
16901 * bin/autom4te.in (load_configuration): Reject #args out of any
16904 2002-10-31 Akim Demaille <akim@epita.fr>
16906 * lib/autoconf/general.m4 (_AC_MSG_LOG_CONFTEST): New.
16907 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE, _AC_LINK_IFELSE)

16920 2002-10-29 Paul Eggert <eggert@twinsun.com>
16922 * doc/autoconf.texi (Particular Functions): AC_FUNC_MALLOC and
16923 AC_FUNC_REALLOC check for compatibility with glibc, not POSIX.
16924 Problem reported by Bruno Haible.
16926 2002-10-29 Akim Demaille <akim@epita.fr>
16928 * doc/autoconf.texi (Header Templates): Put also in words what the
16929 pictures says to assist free style readers.
16930 (Customizing autom4te): s/--cache=/--cache /.
16932 2002-10-29 Akim Demaille <akim@epita.fr>
16934 * lib/autoconf/functions.m4 (_AC_FUNC_VFORK): Include stdlib.h and
16936 sparc_address_test returns void.
16937 Use it with an argument, as prototyped.
16940 2002-10-29 Akim Demaille <akim@epita.fr>
16942 * doc/autoconf.texi (Subdirectories): Cygnus dirs have

17241 Reported by Alexandre Duret-Lutz.
17243 * bin/autom4te.in (&parse_args): Do not prepend `--reload-state'

17263 * lib/Autom4te/General.pm (&update_file): Use `verbose' to report
17264 if some file was changed instead of `print'.
17265 * bin/autoheader.in: Suggest AC_DEFINE with 3 args when needed.

17300 From Sam Varshavchik.
17302 2002-10-08 Akim Demaille <akim@epita.fr>
17304 * bin/autoreconf.in (&autoreconf): Run autopoint before the first
17305 aclocal invocation, as Gettext macros might not be visible to
17307 Instead of blindly running autopoint, scan configure.ac (not the
17308 traces) for AM_GNU_GETTEXT_VERSION uses, as autopoint does.
17309 Reported by Paul D. Smith.
17311 2002-10-08 Paul Eggert <eggert@twinsun.com>
17313 Work around problems found when POSIXLY_CORRECT=1 is set.
17314 None of this seems to have anything to do with POSIX, really,
17315 but it's how Perl getopt works.
17316 * bin/autom4te.in (parse_args): Configure GetOpt with
17318 * doc/autoconf.texi (Invoking autom4te):

17341 * tests/torture.at (Configuring subdirectories): Be robust to

17343 the two last configure runs, using two different sets of
17344 arguments, trigger a legitimate error.

17583 * bin/Makefile.am (autoconf, autoheader, autoreconf, autoupdate)
17584 (ifnames, autoscan, autom4te): Since we don't only depend on
17585 configure.ac variables (such as VERSION etc.), but also on prefix
17586 and so forth, depend on Makefile, not configure.ac.
17587 Reported by Alexandre Duret-Lutz.
17588 * doc/autoconf.texi (Installation Directory Variables): Adjust.
17590 2002-09-05 Kevin Ryde <user42@zip.com.au>
17592 * doc/autoconf.texi (Limitations of Make): HP-UX trailing backslashes
17593 doesn't seem to be confined to ia64, just say "some versions".
17595 2002-09-04 Akim Demaille <akim@epita.fr>
17597 * Makefile.am, doc/Makefile.am: Remove pdf targets, handled by
17599 * Makefile.am (maintainer-clean-local): Remove.
17600 (MAINTAINERCLEANFILES): Remove COPYING.
17602 2002-09-03 Paul Eggert <eggert@twinsun.com>
17604 * doc/autoconf.texi (Configuration Commands): Remove obsolete
17605 example for AC_CONFIG_COMMANDS_PRE. Problem reported by Marcus
17608 2002-09-03 Akim Demaille <akim@epita.fr>
17610 * configure.ac: Bump to 2.53d.
17611 * Makefile.am (AUTOMAKE_OPTIONS): Require 1.6c, i.e., CVS Automake
17612 as of today, on Automake's team suggestion.
17614 2002-09-03 Akim Demaille <akim@epita.fr>
17618 2002-09-02 Akim Demaille <akim@epita.fr>
17620 * bin/autom4te.in (parse_args): Don't honor AUTOM4TE_PATH and
17622 * configure.ac: Disable SITE_MACRO_DIR.
17624 2002-09-02 Jim Meyering <meyering@lucent.com>
17626 * doc/autoconf.texi (AC_SYS_POSIX_TERMIOS): Reflect renaming: s/am/ac/,
17627 i.e., change am_cv_sys_posix_termios to ac_cv_sys_posix_termios.
17628 Also, tweak grammar: s/make sure to/be sure to/.
17630 2002-09-02 Paul Eggert <eggert@twinsun.com>
17632 * doc/autoconf.texi (Limitations of Builtins): Explain why logical
17633 directory names are generally preferable to physical names.
17635 2002-09-02 Akim Demaille <akim@epita.fr>
17637 * lib/Autom4te/General.pm (&update_file): s/die/error/.
17638 Reported by Raja R. Harinath.
17639 * bin/autoheader.in, bin/autoreconf.in, bin/autoscan.in,
17640 * bin/autoupdate.in: Use error instead of die.
17642 2002-09-01 Paul Eggert <eggert@twinsun.com>
17644 * tests/mktests.sh (ac_exclude_egrep, au_exclude_egrep): Use
17645 ordinary shell concatenation rather than echo+tr+sed command that
17646 runs afoul of a long-line-related sed bug in Solaris 8.
17648 * bin/autoheader.in (parse_args): --warning -> --warnings.
17650 * bin/autoconf.as: Work even if "ls" outputs "FOO not found" to
17651 stdout, as traditional "ls" does.
17652 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT,
17653 _AC_COMPILER_EXEEXT_O): Likewise.
17654 * doc/autoconf.texi (Limitations of Usual Tools): Add "ls".
17656 * bin/autoconf.as: Add --prepend-include option. This patch was
17657 applied to bin/autoconf.in in the 2002-07-17 patch by Mark D. Roth,
17658 but bin/autoconf.in is generated automatically from bin/autoconf.as.
17660 * bin/autoconf.in, configure: Regenerate.
17662 * doc/autoconf.texi (Special Shell Variables): Mention
17663 ENV, MAIL, MAILPATH, PS1, PS2, PS4. Index PWD.
17665 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Unset ENV, MAIL,
17666 MAILPATH and set PS1, PS2, PS4 to default values, to work
17667 around bug in pre-3.0 UWIN ksh reported by Bruce Lilly.
17668 For LC_ALL etc, first try to set to "C" as POSIX requires and as
17669 the Autoconf documentation specifies; fall back to "unset" only if
17670 this fails. Use a shell for-loop for this rather than an m4 loop,
17671 to shorten the output script.
17673 2002-08-30 Paul Eggert <eggert@twinsun.com>
17675 * doc/autoconf.texi (Special Shell Variables): Mention POSIX
17676 1003.1-2001's requirements for CDPATH. Give a simpler workaround
17677 for the CDPATH problem. Document PWD.
17678 (Limitations of Builtins): Document the problem that "cd $foo" and
17679 "ls $foo" may refer to different directories in shells conforming
17680 to POSIX 1003.1-2001. Use PS1 rather than CDPATH for "unset"
17681 example, since the old example is now out of date.
17683 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Reject FOO if "cd
17684 FOO" and "ls FOO" talk about different directories; this catches
17685 problems when POSIX 1003.1-2001 "cd" fails due to symlink
17688 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Use AS_UNSET instead
17689 of rolling our own unset.
17690 (_AS_PREPARE): $as_unset CDPATH instead of AS_UNSETting it, since
17691 in practice we needn't worry about CDPATH if unset doesn't work.
17693 * Makefile.in, aclocal.m4, bin/Makefile.in,
17694 config/Makefile.in, doc/Makefile.in, lib/Makefile.in,
17695 lib/Autom4te/Makefile.in, lib/autoconf/Makefile.in,

17697 lib/emacs/Makefile.in, lib/m4sugar/Makefile.in, man/Makefile.in,
17698 tests/Makefile.in: Regenerate with Automake 1.6.3.
17700 * config/config.guess, config/config.sub, config/mkinstalldirs:
17703 * configure: Regenerate with self.
17705 2002-08-30 Kevin Ryde <user42@zip.com.au>

17715 2002-08-29 Akim Demaille <akim@epita.fr>
17717 * lib/Autom4te/General.pm (&xqx): New.
17718 (&xsystem): Use WIFEXITED and WEXITSTATUS instead of decoding $? by
17719 hand, which is not portable.
17721 * bin/autom4te.in: Use them.
17722 Use &error instead of die.
17723 * tests/m4sugar.at (m4_warn, m4_require: circular dependencies):
17726 2002-08-17 Paul Eggert <eggert@twinsun.com>
17728 * lib/autoconf/fortran.m4 (AC_PROG_F77): Remove fc from the
17729 default list of compilers to try, since it was long ago superseded
17730 by the ksh fc builtin. Suggested by Steven G. Johnson.
17732 2002-07-31 Alexandre Duret-Lutz <duret_g@epita.fr>
17734 * doc/autoconf.texi (Invoking autom4te): End the option table,
17735 fixing a bug introduced by the previous patch.
17736 (Limitations of Make): Add a 'target lookup' subentry in the
17737 'VPATH' entry. Rewrite all `make' occurences as `@command{make}'.
17739 2002-07-29 Mark D. Roth <roth@feep.net>
17741 * bin/autom4te.in: Remove --include-envvar and --site-macro-subdir
17742 options and use $AUTOM4TE_PATH.
17743 * doc/autoconf.texi: Remove documentation of autom4te
17744 --include-envvar and --site-macro-subdir options and document
17745 use of $AUTOM4TE_PATH.
17746 * lib/autom4te.in: Remove --include-envvar and --site-macro-subdir
17747 arguments from each language section.
17749 2002-07-29 Paul Eggert <eggert@twinsun.com>
17751 * doc/install.texi: Include copyright symbol in copyright notice.
17753 * Makefile.am (MAKEINFO): Remove; it's a user-specified macro.
17755 (AM_MAKEINFOFLAGS): New macro.
17756 * doc/Makefile.am (MAKEINFO, AM_MAKEINFOFLAGS): Likewise.
17757 * Makefile.am (INSTALL): Use the new macros.
17758 Use -o rather than --output, since "missing" does not grok --output.
17760 2002-07-25 Alexandre Duret-Lutz <duret_g@epita.fr>
17762 * doc/autoconf.texi (Limitations of Make): Escaped newlines in
17763 comments do not always work. Never trust the exit status of
17766 2002-07-24 Kevin Ryde <user42@zip.com.au>
17768 * doc/autoconf.texi (Limitations of Make, Making testsuite Scripts):
17769 Untabify, since tabs are not enjoyed by texi2dvi and makeinfo.
17771 2002-07-23 Paul Eggert <eggert@twinsun.com>
17773 * lib/m4sugar/m4sh.m4 (_AS_PATH_SEPARATOR_PREPARE):
17774 Use PATH="/nonexistent;.", not PATH=".;.", as FreeBSD ksh2002
17775 apparently treats PATH="nonexistent" as if it contained ".".
17776 Bug reported by Stefan `Sec' Zehl.
17778 2002-07-22 Alexandre Duret-Lutz <duret_g@epita.fr>
17780 * doc/autoconf.texi (Limitations of Make): Mention the special

18059 (AC_FUNC_FNMATCH): Use it. Test only for POSIX conformance,
18060 not for GNU extensions; this undoes part of the 2000-11-03 change,
18061 reverting to 2.13-compatible behavior.
18062 Add new optional argument DIR.
18063 (AC_FUNC_FNMATCH_GNU): New macro.
18065 * lib/autoconf/specific.m4 (AC_GNU_SOURCE): New macro.
18067 2002-05-08 Paul Eggert <eggert@twinsun.com>
18069 * lib/autoconf/headers.m4 (AC_HEADER_TIOCGWINSZ):
18070 Don't require AC_SYS_POSIX_TERMIOS. The test is unnecessary,
18071 and it causes a 'test' syntax error if it fails.
18072 Bug reported by Stephen Gildea.
18074 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
18075 If prototypes are supported, use them to check this at compile-time,
18076 instead of trying to check it at run-time. If we must do a run-time
18077 check, assume that setvbuf is standard when cross-compiling, as
18078 nonstandard setvbuf occurs only on ancient and unlikely hosts.
18079 Bug reported by Paul D. Smith.
18081 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Add optional
18082 argument specifying location of getloadavg.c. This removes a
18083 FIXME. This idea was taken from Jim Meyering's implementation in
18085 * doc/autoconf.texi (Particular Functions): Document this.
18086 Also, mention HAVE_NLIST_H rather than NLIST_STRUCT, since
18087 that's what the code does; this fixes a bug reported by
18090 2002-05-03 Akim Demaille <akim@epita.fr>
18092 * bin/autoreconf.in (autoreconf): Rewrite to use Gettext's
18093 autopoint instead of gettextize.
18094 ($uses_alocal): Rename as...
18095 ($uses_aclocal): this.
18096 * doc/autoconf.texi (autoreconf Invocation): Adjust.
18097 Suggested by Bruno Haible.
18099 2002-05-03 Akim Demaille <akim@epita.fr>
18101 * lib/m4sugar/m4sugar.m4 (m4_map_sep): New.
18103 2002-04-29 Paul Eggert <eggert@twinsun.com>
18105 * bin/autoreconf.in (autoreconf): Don't age aclocal.m4's input
18106 files to be 1 second older; just set them to be the same time.
18107 Also, sleep 1 second after the first aclocal, to work around
18108 problems with sub-second time stamps on the input files.
18110 2002-04-29 Thien-Thi Nguyen <ttn@gnu.org>
18112 * doc/autoconf.texi: Mention "set -e -x" lossage
18113 under node "Limitations of Builtins".
18115 2002-04-29 Akim Demaille <akim@epita.fr>
18117 * doc/install.texi: Better wording for setting variables when
18119 From Christian Cornelssen.
18121 2002-04-29 Akim Demaille <akim@epita.fr>
18123 * tests/m4sh.at (LINENO): If testsuite itself is rewritten because
18124 of lack of $LINENO support, then the test will compare the $LINENO
18125 in testsuite vs. the lineno in the test file. This is wrong, of
18127 Be sure to protect it.
18128 Reported by Patrick Welche.
18130 2002-04-25 Akim Demaille <akim@epita.fr>
18132 * doc/autoconf.texi (Obsolete Macros): Typo.
18133 Reported by Vladimir Volovich.
18135 2002-04-25 Akim Demaille <akim@epita.fr>
18137 * bin/autoreconf.in (autoreconf): Don't let aclocal.m4 be older
18138 than some of the input files, hence, on the second run of aclocal,
18139 if some of its input are younger, make them older.
18140 Suggested by Paul Eggert.
18142 2002-04-25 Akim Demaille <akim@epita.fr>
18144 * doc/autoconf.texi (Limitations of Usual Tools): sed and `!'.

18149 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Let ac_subst_files
18150 and ac_subst_vars be sh variables containing the list of
18151 AC_SUBST_FILES'ed and AC_SUBST'ed identifiers. Output them in the
18153 (_AC_INIT_PREPARE): Use them to log them.
18154 (_AC_SUBST, _AC_SUBST_SED_PROGRAM): Remove.
18155 (AC_SUBST, AC_SUBST_FILE): Instead of buliding the
18156 _AC_SUBST_SED_PROGRAM, store the list of output files/variables in
18157 _AC_SUBST_FILES and _AC_SUBST_VARS.
18158 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Adjust.
18160 2002-04-24 Akim Demaille <akim@epita.fr>
18162 * bin/autoreconf.in (autoreconf): Run automake after autoconf and
18163 autoheader, so that automake does not complain about a missing
18164 config.h.in that was to be created.
18166 2002-04-23 Akim Demaille <akim@epita.fr>
18168 * bin/autoheader.in (parse_args): --warning takes an argument.
18171 2002-04-22 Peter Eisentraut <peter_e@gmx.net>
18173 * lib/autoconf/general.m4 (_AC_RUN_IFELSE): Remove gmon.out

18218 Minor spelling and grammar fixes.
18220 * doc/autoconf.texi: Follow the outline suggested in the GNU
18221 Sample Texts sections of the Texinfo 4.2 manual. Most
18222 importantly, this makes sure that the copyright notices appear in
18223 all output formats. You probably need Texinfo 4.2 to generate

18248 that is not portable to Zsh.
18250 2002-04-19 Alexandre Duret-Lutz <duret_g@epita.fr>
18252 * bin/autoupdate.in (handle_autoconf_macros): Honor AU_DEFUNs
18253 from aclocal.m4 too.

18261 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Install the Zsh
18262 workaround for ${1+"$@"}.
18263 * doc/autoconf.texi (Shell Substitutions): Explain it.
18264 From Oliver Kiddle and Peter Stephenson.
18266 Have M4sh perform minimal shell sanitizing.
18268 * lib/m4sugar/m4sh.at (AS_SHELL_SANITIZE): Split the `_AS_PREPARE_*'
18270 (_AS_PREPARE): this new macro.
18272 (AS_INIT): Invoke AS_SHELL_SANITIZE.
18273 * tests/m4sh.at (AT_DATA_LINENO): Use _AS_PREPARE.
18275 Adjust Autoconf and Autotest.
18277 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Don't invoke
18278 AS_SHELL_SANITIZE, AS_INIT did it, but invoke AS_PREPARE.
18279 * lib/autotest/general.m4 (AT_INIT): Likewise.
18280 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
18281 Invoke _AS_PREPARE (not AS_PREPARE) in addition to
18284 Use this M4sh to generate Autoconf's shell scripts.
18286 * tests/wrapsh.as: New, precursor of wrapsh.in.
18287 * tests/Makefile.am: Include lib/freeze.mk to get the dependencies
18288 on Autotest and M4sh.
18289 ($(TESTSUITE)): Use $(autotest_m4f_dependencies).
18290 (wrapsh.in): New target.
18291 * bin/autoconf.as: New, precursor of autoconf.in.

18306 * doc/autoconf.texi (Systemology): Add link to Unix V7 online docs.
18307 (Portable Shell): Cross reference to Systemology.
18309 2002-04-05 Akim Demaille <akim@epita.fr>
18311 * bin/autoreconf.in (autoreconf): Be sure to accumulate the
18312 directories when descending in a SUBDIRS.
18313 Reported by Ezra Peisach.
18315 2002-04-04 Andreas Schwab <schwab@suse.de>
18317 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Only simplify if path
18318 contains no literal separators.

18322 * lib/autoconf/status.m4 (_AC_CONFIG_FILE, _AC_CONFIG_HEADER)
18323 (_AC_CONFIG_COMMAND, _AC_CONFIG_LINK): New.
18324 Use dnl, not the KILL diversion.
18326 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_COMMANDS)
18327 (AC_CONFIG_LINKS): here.
18329 Don't use the KILL diversion, as it kills spurious output, which
18330 results in failures being hidden.
18331 Use m4_defn where appropriate.
18332 (AC_CONFIG_IF_MEMBER): Kill the real bug: a spurious parenthesis
18333 after the second argument.
18335 * lib/autom4te.in (Autoconf, Autotest, M4sh): Don't pass --warning
18336 syntax, as it is provided by M4sugar.

18339 2002-04-03 Andreas Schwab <schwab@suse.de>

18358 Integrate AC_PROG_CC_STDC into AC_PROG_CC.

18361 AU_DEFUN old name. Use _AC_COMPILE_IFELSE.
18362 (AC_PROG_CC): Call _AC_PROG_CC_STDC.

18378 * lib/autoconf/c.m4 (AC_C_INLINE): Test with a typedef return value,
18379 to avoid versions of HP C which don't allow that.
18381 2002-03-27 Paul Eggert <eggert@twinsun.com>
18383 * lib/m4sugar/m4sh.m4 (_AS_BASENAME_PREPARE): New macro.

18395 2002-03-25 Paul Eggert <eggert@twinsun.com>
18397 * tests/m4sh.at: Don't rely on "PATH=test:$PATH test-1" working
18398 as POSIX requires, as it doesn't work with Zsh.
18399 * doc/autoconf.texi (Assignments): Document the problem.
18401 2002-03-25 Alexandre Duret-Lutz <duret_g@epita.fr>
18403 * doc/autoconf.texi (Limitations of Make): Mention more issue
18404 about VPATH, overriding of macros in sub-makes, and handling of
18407 2002-03-21 Paul Eggert <eggert@twinsun.com>
18409 * doc/autoconf.texi (Here-Documents): Mention Solaris 8 dtksh
18410 problem with here-document buffer boundaries.
18412 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Unset ENV and BASH_ENV
18413 when reinvoking the shell, to work around problems with installers
18414 who put strange things like "cd" commands in their environments.
18416 2002-03-19 Akim Demaille <akim@epita.fr>

18438 * doc/autoconf.texi (Programming in M4sh): Add AS_MKDIR_P.
18439 (Limitations of Usual Tools): Add mkdir section.
18441 * lib/m4sugar/m4sh.m4 (_AS_MKDIR_P_PREPARE): New macro.
18442 (AS_MKDIR_P): Require it. Use mkdir -p if available, falling
18443 back on AS_DIRNAME to compute prefixes otherwise; this is
18444 roughly what mkinstalldirs does. That way, we need not have
18445 our own filename disassembler. The old disassembler did not
18446 work with Solaris 8 dtksh, which is ksh Version M-12/28/93d.
18448 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP):
18449 Create at_test_all by a series of assignments,
18450 not by a single assignment of a long string. The latter causes ksh
18451 version 11/16/88g to silently misbehave on OpenServer 5.0.6a,
18452 presumably because of a buffer overrun.
18454 2002-03-14 Paul Eggert <eggert@twinsun.com>
18456 * lib/autotest/general.m4 (at_times_skip):
18457 Renamed from at_times. Now a boolean.
18458 ksh93 Version M-12/28/93d doesn't like 'x=times; $x'; it
18459 says 'times: not found'.

18500 subdirectory should exist.
18502 2002-03-08 Akim Demaille <akim@epita.fr>
18504 * Makefile.am (AUTOMAKE_OPTIONS): 1.6.
18506 2002-03-08 Akim Demaille <akim@epita.fr>
18508 * bin/autom4te.in (&handle_m4): Do not foreach with `$_' as it
18509 aliases the actual variables, and modifications of the former
18512 2002-03-08 Akim Demaille <akim@epita.fr>
18514 * bin/autom4te.in (&handle_m4): Protect us from corrupted file
18515 because of C-c: have m4 output in tmp files, then mv them.
18517 2002-03-08 Akim Demaille <akim@epita.fr>

18553 (Hosts and Cross-Compilation): this new section.
18554 * doc/install.texi (System Type): Ditto.
18555 * lib/autoconf/general.m4 (AC_CANONICAL_HOST): Explicitly state
18556 that `--host' implies cross-compilation.
18558 2002-03-04 Akim Demaille <akim@epita.fr>
18560 * doc/autoconf.texi (Evaluation Macros): New.
18561 * lib/m4sugar/m4sugar.m4 (m4_lquote): Remove, it is totally
18563 (_m4_foreach): Define the variant with immediate evaluation so
18564 that it contains exactly the items, not an expression which
18565 evaluation is the current item.
18566 (m4_re_string, m4_re_word): Don't over quote them.
18568 2002-03-04 Akim Demaille <akim@epita.fr>
18570 Instead of having stacking `shift's evaluated at the end, let
18571 `foreach' loops immediately evaluate them.
18573 * lib/m4sugar/m4sugar.m4 (m4_quote, m4_dquote): Use $@ rather than
18574 $*. This is the n-th time I change my mind, but hopefully this is
18577 (m4_text_wrap): Use m4_foreach, which is finally correct _and_
18579 (m4_foreach_quoted, m4_car_quoted, _m4_foreach_quoted): Remove, as
18580 it was only a hack for m4_text_wrap.
18581 (m4_car2): Remove, replaced by...
18583 (_m4_foreach): Adjust.
18584 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Adjust, and use
18585 m4_bpatsubst for clarification.

18607 message to be sent.
18609 2002-02-28 Kevin Ryde <user42@zip.com.au>

18613 2002-02-25 Akim Demaille <akim@epita.fr>
18615 * lib/autoconf/functions.m4 (AC_FUNC_SETPGRP): Fix the test.

18634 2002-02-07 Akim Demaille <akim@epita.fr>
18636 Fix Autoconf PR/207:
18637 AC_PREFIX_PROGRAM fails with dashed program names
18639 * lib/autoconf/general.m4 (AC_PREFIX_PROGRAM): Just use a fresh
18640 variable when looking for the prefix program.
18641 Now it also works for shell variables.

18651 case/esac, some shells don't support it.
18652 Reported by Zack Weinberg.

18655 2002-02-06 Akim Demaille <akim@epita.fr>
18657 * lib/autotest/general.m4 (AT_INIT): When handling --keywords, be
18658 sure not to introduce newlines in at_groups.
18659 * lib/autotest/Makefile.am (autotest.m4f): Typo.
18661 2002-02-06 Akim Demaille <akim@epita.fr>
18663 * tests/torture.at (Configuring subdirectories): Skip if aclocal
18666 2002-02-05 Paul Eggert <eggert@twinsun.com>
18668 * doc/autoconf.texi (Specific Compiler Characteristics):
18669 Describe HP-UX cc bug workaround more accurately.
18670 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Cast to long,
18672 * tests/semantics.at (AC_CHECK_SIZEOF): Check non-GCC
18673 cross-compilers, too. This undoes some of the most recent change
18676 2002-02-05 Akim Demaille <akim@epita.fr>
18678 * tests/Makefile.am (check_SCRIPTS): Use it, instead of WRAPPERS,
18679 to make sure they are up to date when `check' is run.
18681 2002-02-05 Akim Demaille <akim@epita.fr>
18683 * doc/autoconf.texi (Making testsuite Scripts): Document
18686 2002-02-05 Akim Demaille <akim@epita.fr>
18688 * lib/freeze.mk: New.
18690 2002-02-05 Akim Demaille <akim@epita.fr>
18692 Implement `autom4te --freeze'.
18694 * bin/autom4te.in (&freeze): New.
18695 * lib/autoconf/autoconf.m4, lib/autotest/general.m4,
18696 * lib/m4sugar/m4sh.m4: Don't include files given by autom4te.
18698 2002-02-05 Akim Demaille <akim@epita.fr>
18700 * bin/autom4te.in (&parse_args): Implement `frozen files are
18701 optional are the sum of the previous files on the command line'.
18702 Also, pass `--reload-state=' on them, so...
18703 (handle_m4): don't.
18704 * lib/autom4te.in (Autotest, Autoconf): Rely on M4sh.
18705 (M4sh): Rely on M4sugar.
18706 (Autotest, M4sh, M4sugar): Use frozen files.
18708 2002-01-31 Akim Demaille <akim@epita.fr>
18710 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Accept $4.

18715 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Map non
18716 alphanumeric to `-' instead of `_'.
18718 2002-01-30 Akim Demaille <akim@epita.fr>
18720 * tests/semantics.at (AC_CHECK_SIZEOF): Split into two tests: one
18721 for plain code, the other for cross-compilation code. The latter
18722 is now run with GCC only.

18738 2002-01-28 Akim Demaille <akim@epita.fr>
18740 * doc/autoconf.texi (Writing testsuite.at): AT_CLEANUP no longer
18743 2002-01-28 Akim Demaille <akim@epita.fr>
18745 * lib/autotest/general.m4 (AT_INIT): Don't be ridiculous: adjust
18746 AUTOTEST_PATH *after* it was set.
18747 Don't put `.' in the PATH: the user should be precise and `./' if
18748 needed. In addition, given that the test suite does some `cd', if
18749 `.' is in the path, the `tested programs' sections will report
18750 programs found in the test suite's directory, while during the
18751 tests (performed in their own directory), these programs are no
18752 longer visible. In other words, the results is confusing and
18754 * tests/m4sh.at: Adjust: don't rely on `.' being in the PATH.

18765 2002-01-24 Akim Demaille <akim@epita.fr>
18767 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Use PATH_SEPARATOR.
18768 (_AS_PATH_SEPARATOR_PREPARE): Don't expect $SHELL to be
18769 Bourne. Use /bin/sh.
18770 From Andreas Buening.
18772 2002-01-24 Akim Demaille <akim@epita.fr>
18774 * config/config.guess, config/config.sub, config/texinfo.tex:

18792 2002-01-21 Akim Demaille <akim@epita.fr>

18796 2002-01-21 Akim Demaille <akim@epita.fr>
18798 * lib/Autom4te/General.pm (getopt): Use a more GNUish error
18799 message on invalid options.
18800 * bin/autom4te.in (parse_args): Don't use
18801 Autoconf::General::getopt with non valid options.
18803 2002-01-17 Jim Meyering <meyering@lucent.com>
18805 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Initialize
18806 $ac_cv_exeext so we don't use an old, invalid, cached value.
18808 2002-01-11 Akim Demaille <akim@epita.fr>
18810 * lib/autoconf/functions.m4 (AC_FUNC_STRNLEN): New, from Jim

18817 2002-01-06 Akim Demaille <akim@epita.fr>
18819 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Don't create
18820 package.m4, since is really depends upon configure.ac, not
18822 * doc/autoconf.texi (testsuite Scripts): Adjust.
18823 * tests/Makefile.am (package.m4): New.
18824 EXTRA_DIST it since its a source.
18826 2002-01-06 Akim Demaille <akim@epita.fr>
18828 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Move the AC_SUBST
18829 of PACKAGE_NAME, PACKAGE_TARNAME, PACKAGE_VERSION, PACKAGE_STRING,
18830 and PACKAGE_BUGREPORT from here...
18831 (_AC_INIT_DEFAULTS): to here, since it is unrelated to the
18833 (_AC_INIT_PREPARE): AC_DEFINE these symbols.
18834 * lib/autotest/general.m4: Use AT_PACKAGE_*, not PACKAGE_*.
18835 (AT_INIT): No longer catch `^PACKAGE_(BUGREPORT|STRING)$'.
18836 * tests/tools.at (autoheader): Adjust.
18837 * tests/atspecific.m4 (AT_CHECK_DEFINES): Adjust.
18839 2002-01-06 Akim Demaille <akim@epita.fr>

18854 2001-12-17 Jim Meyering <meyering@lucent.com>
18856 * doc/autoconf.texi (New Macros): Tweak wording.
18858 2001-12-14 Akim Demaille <akim@epita.fr>
18860 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): We cleaning up the
18861 trailing files, don't apply `-rf' to files which might not be
18862 created by configure (core, core.*, and *.core), but just `rm -f'.
18863 Suggested by Jonathan Kamens.
18865 2001-12-14 Aaron M. Ucko <amu@alum.mit.edu>
18867 * lib/autoconf/general.m4: Avoid duplicates in `$ac_configure_args'.
18869 2001-12-14 Akim Demaille <akim@epita.fr>
18871 * Makefile.am (MAINTAINERCLEANFILES): Remove configure.
18873 2001-12-13 Peter Eisentraut <peter_e@gmx.net>
18875 * lib/autoconf/status.m4 (_AC_SRCPATHS): Rename buildpath to
18876 abs_builddir, top_buildpath to abs_top_builddir, srcpath to
18877 abs_srcdir, top_srcpath to abs_top_srcdir.
18878 (_AC_OUTPUT_FILES): Adjust.
18879 * NEWS, doc/autoconf.texi, lib/autoconf/autotest.m4,
18880 * tests/atspecific.m4, tests/autoreconf.in, tests/tools.at,
18881 * tests/wrappl.in, tests/wrapsh.in: Adjust.
18883 2001-12-12 Steven G. Johnson <stevenj@alum.mit.edu>
18885 * lib/autoconf/fortran.m4 (_AC_PROG_F77_V_OUTPUT): Fix failed
18886 C/Fortran linking on HP/UX, by extracting the Fortran library
18887 search path from the LPATH line in the $F77 -v output.
18889 2001-12-12 Kevin Ryde <user42@zip.com.au>
18891 * doc/autoconf.texi (File Descriptors): Use a clearer layout for the
18892 forbidden file descriptors table.
18894 2001-11-26 Akim Demaille <akim@epita.fr>
18896 * bin/autoscan.in (%c_keywords): Build it at top level.
18897 Map to 1 in order to simplify its uses.
18899 2001-11-26 Akim Demaille <akim@epita.fr>
18901 * bin/autoscan.in (&scan_c_file, &scan_sh_file, &scan_makefile):
18902 Remove $filepath, useless.
18903 (&scan_makefile): Don't remove the $(FOO), ${FOO} and @FOO@
18904 variables, they are really part of the tokens.
18905 Split the input line on spaces and then look for tokens.
18906 Now autoscan ceases to ask for AC_PROG_LEX for the package Bison
18907 because of `lex$U.$(OBJEXT)'.
18908 (&scan_files): Use "@list" instead of join.
18909 * doc/Makefile.am (CLEANFILES): Add *.fns.
18911 2001-11-26 Akim Demaille <akim@epita.fr>
18913 * tests/autoreconf.in, tests/autom4te.in, tests/autoupdate.in:
18914 Remove, replaced by...
18915 * tests/wrappl.in: Be common for all the Perl executables.
18916 In particular autoscan and autoheader want -I.
18917 * configure.ac: Adjust.
18918 * lib/autoscan/headers: errno.h is portable.
18920 2001-11-26 Akim Demaille <akim@epita.fr>
18922 * bin/autoscan.in (used): New.
18925 2001-11-26 Akim Demaille <akim@epita.fr>

18937 comment made the whole line be ignored.
18939 2001-11-26 Akim Demaille <akim@epita.fr>
18941 * doc/autoconf.texi (Using an Autotest Test Suite): New.
18942 (testsuite Scripts): Be one of its subsection.
18943 (Autotest Logs): New.
18945 2001-11-26 Akim Demaille <akim@epita.fr>
18947 Test groups are now run two directories deeper.
18949 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Replace srcdir,
18950 top_srcdir and top_builddir with at_srcdir, at_top_srcdir and
18952 * lib/autotest/general.m4 (AT_INIT): Compute srcdir,
18953 top_srcdir, builddir and top_builddir.
18954 Use `at_*dir' relatively to the directory containing the
18955 suite, use `*dir' when relatively to the current group dir.

18960 lib/autoconf/functions.m4, lib/autoconf/headers.m4,
18961 tests/atgeneral.m4, tests/tools.at, tests/atspecific.m4: Fix
18964 2001-11-22 Alexandre Duret-Lutz <duret_g@epita.fr>
18966 * doc/autoconf.texi (Using System Type): Add an example of `case
18967 $host' usage so people quit using `case $target' everywhere.
18969 2001-11-22 Akim Demaille <akim@epita.fr>
18971 * doc/autoconf.texi (Installation Directory Variables): Englishoes
18972 spotted by Jim Meyering.
18974 2001-11-16 Paul Eggert <eggert@twinsun.com>
18976 This patch implements a `long double' suggestion by Oliver Kiddle.
18978 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C)): Make the array
18979 static, to catch errors if the value isn't known at compile-time
18980 and the compiler supports dynamic arrays. Change its name from
18981 `_array_' to `test_array' to avoid potential name clashes.
18982 (AC_C_LONG_DOUBLE): Make it a compile-time test, not a run-time
18983 test. Do not define HAVE_LONG_DOUBLE if `long double' is no
18984 better than double. Catch a bug in GCC 2.95.2 x86.
18985 * doc/autoconf.texi (C Compiler): Document the above.
18988 2001-11-13 Akim Demaille <akim@epita.fr>
18990 * tests/m4sh.at (LINENO): Protect from autom4te's substitution by
18992 * tests/tools.at: Don't protect dnl, AT_DATA_M4SH does.
18994 2001-11-13 Akim Demaille <akim@epita.fr>
18996 * lib/autotest/general.m4 (AT_INIT): After having run the test
18997 group, go back to the initial directory, not to at_suite_dir.
18999 2001-11-13 Akim Demaille <akim@epita.fr>
19001 * tests/atspecific.m4 (AT_DATA_M4SUGAR, AT_DATA_M4SH)
19002 (AT_DATA_AUTOCONF): Also protect @&t@ from autom4te.
19003 (AT_CHECK_AUTOCONF, AT_CHECK_AUTOHEADER): Pass no --include
19005 (AT_CHECK_CONFIGURE): Use absolute paths.
19006 (_AT_CHECK_AC_MACRO): Create aclocal.m4 with AC_STATE_SAVE in it.
19007 The problem is still the old one: there is no means in M4 (that I
19008 know about) to create a defining macro, because there is no means
19009 to create `$1' etc., therefore, the defining macro ``swallows''
19010 all the arguments meant to the defined macro.
19012 2001-11-13 Akim Demaille <akim@epita.fr>
19014 * tests/atspecific.m4 (AT_DATA_AUTOCONF): New.
19015 (AT_CONFIGURE_AC): Output the definition of AC_STATE_SAVE in
19017 * tests/aclocal.m4: Remove, as it is no longer used.
19019 2001-11-13 Akim Demaille <akim@epita.fr>
19021 * lib/autotest/general.m4: Change `tests?' into `groups?' in
19022 variable names when referring to a single test group, or to
19023 `suite' when referring to the whole test suite.
19024 `at_last_test' is removed: m4 compute at_format itself.
19025 (at_stdout, at_stder1, at_stderr): New variables.
19026 (AT_CHECK): Use them.
19028 2001-11-13 Akim Demaille <akim@epita.fr>
19030 * lib/autotest/general.m4 (AT_INIT): Be sure to put `.', relative,
19032 Create `testsuite.dir/003/run' instead of `testsuite.003'.
19033 Do it as soon as a test fails, don't wait till the end of the test
19035 Don't remove $as_me.[0-9]*, since these files no longer exist.
19037 2001-11-13 Akim Demaille <akim@epita.fr>
19039 * tests/tools.at: Use absolute paths, since we are no longer run
19042 2001-11-13 Akim Demaille <akim@epita.fr>
19044 Now that tests are running in their own private dir, there is no
19045 need to list the files to remove at the end of tests groups.
19047 * lib/autotest/general.m4 (_AT_CLEANUP_FILE, AT_CLEANUP_FILES):
19048 (AT_data_files, at_data_files): Remove.
19049 (AT_CLEANUP, AT_DATA): Simplify.
19051 Remove the group dir if !debug && !failed.
19052 * tests/atspecific.m4: Adjust.
19054 2001-11-13 Akim Demaille <akim@epita.fr>
19056 Start a new layout for Autotest: `testsuite' creates
19057 `testsuite.dir' in which the at-check-line etc. files are to be
19058 found, and `testsuite.dir/003' where the test group 3 is run.
19060 * lib/autotest/general.m4 (AT_INIT): at_tests_dir,
19061 at_check_line_file, at_format, at_test_normalized, at_group_dir
19063 Create the directories.
19064 Use absolute paths for at- files.

19067 2001-11-11 Michael Matz <matz@kde.org>
19069 * m4sugar.m4 (_m4_foreach): Make it linear instead quadratic.

19102 2001-11-12 Akim Demaille <akim@epita.fr>
19104 * lib/autoconf/programs.m4 (_AC_PROG_LEX_YYTEXT_DECL): Use
19105 AC_TRY_EVAL to run $LEX, not AC_TRY_COMMAND. This validates the
19106 definition used by Automake where LEX is +/- "${missing} lex" and
19107 `missing' itself contains variables.
19109 2001-11-12 Akim Demaille <akim@epita.fr>
19111 * lib/autotest/general.m4 (AT_INIT): Push KILL at the end.
19112 Now that M4sh pushes BODY, the comments were output at the end of
19115 2001-11-08 Akim Demaille <akim@epita.fr>
19117 * bin/autoreconf.in (&autoreconf): Run aclocal before tracing, so
19118 that we can trace macros from aclocal.m4.
19119 Trace AC_PROG_LIBTOOL, not AM_PROG_LIBTOOL, since the latter is
19120 obsoleted, and redirect to the former anyway.
19121 Reported by Ralf Corsepius.
19123 2001-11-08 Akim Demaille <akim@epita.fr>
19125 * bin/autoreconf.in (&autoreconf): AC_CONFIG_SUBIDRS are to be
19126 processed only if present.
19127 * tests/torture.at (Configuring subdirectories): Use autoreconf
19128 instead of successive calls to autoconf.
19129 Add a nonexistent subdirectory to exercise the patch above.
19130 Reported by Ralf Corsepius.
19132 2001-11-08 Kevin Ryde <user42@zip.com.au>
19134 * doc/autoconf.texi (Limitations of Usual Tools): Note HP-UX cc

19154 ($(TESTSUITE)): this.
19157 2001-11-05 Alexandre Duret-Lutz <duret_g@epita.fr>
19159 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): When removing
19160 the --prefix option, also remove it's argument.

19178 * bin/autoreconf.in (&parse_args): Trim the configure.ac part of
19180 Default @ARGV to `.', not find_configure_ac.
19181 (&autoreconf): Argument is a directory.
19182 Trace AC_CONFIG_SUBDIRS and schedule the subdirs for autoreconf'ing.
19183 * doc/autoconf.texi (autoreconf Invocation): Update.
19185 2001-11-03 Akim Demaille <akim@epita.fr>
19187 * lib/Autom4te/General.pm (@export_vars, @export_subs)
19188 (@export_forward_subs): New.
19189 Add basename, dirname, and fileparse.
19191 * bin/autoreconf.in (&autoreconf): Fix call to fileparse.
19192 Don't look for aclocal flags if we already know aclocal is not
19194 Move aclocal.m4t only if it exists.
19195 Reported by Ezra Peisach.
19197 2001-11-03 Akim Demaille <akim@epita.fr>
19199 * bin/autoreconf.in (&parse_args): Work only on the configure.ac
19200 passed on command line, defaulting to ./configure.ac if present.
19201 (&maybe_autoreconf, File::Find): Remove, unused.
19202 (&autoreconf): If autoconf is not used, don't try to trace.
19204 2001-11-02 Akim Demaille <akim@epita.fr>
19206 * configure.ac: Bump to 2.52g.

19215 * config/lispdir.m4: Update from masters.
19216 * configure.ac: Bump to 2.52f.
19218 2001-11-02 Akim Demaille <akim@epita.fr>

19221 Don't run aclocal when aclocal.m4 is not from aclocal.
19223 Don't run libtoolize and gettextize if --install is not given.
19225 2001-11-01 Paul Eggert <eggert@twinsun.com>
19227 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): _AS_CR_PREPARE needs to
19228 be invoked before _AS_LINENO_PREPARE.
19229 (_AS_LINENO_PREPARE): Use as_cr_digits and as_cr_alnum rather
19230 than character ranges.
19232 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Fix NLS before
19233 invoking AS_BASENAME. Set the locale variables to 'C' if
19234 possible, as POSIX requires this to get the traditional
19236 * doc/autoconf.texi (Special Shell Variables): Describe the above.
19238 2001-10-31 Paul Eggert <eggert@twinsun.com>
19240 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): Do not surround body
19241 with {}, as that triggers a bug in Bash 2.05.
19243 (_AS_LINENO_PREPARE): Use Sed rather than
19244 Awk. Fix the sed prepass to work even if there are multiple
19245 instances of $LINENO on the same line. Do not substitute for
19246 other variables like $LINENOT. Do not check file dates; such a
19247 check is unreliable on sufficiently fast machines, and removing
19248 the check makes the code simpler and more reliable. Check for
19249 output and chmod failures.
19251 * doc/autoconf.texi (Special Shell Variables): Document
19254 2001-10-31 Akim Demaille <akim@epita.fr>

19259 2001-10-31 Akim Demaille <akim@epita.fr>
19261 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Do not
19262 AC_CONFIG_FILES(atlocal) as it means a file atlocal.in *must* be
19263 provided, while it is optional.
19264 * configure.ac: Adjust.
19266 2001-10-26 Paul Eggert <eggert@twinsun.com>
19268 * NEWS, README, configure.ac, lib/Autom4te/General.pm,
19269 lib/Autom4te/Struct.pm:
19270 Require Perl 5.005_03 instead of just 5.005, as some tests fail
19273 * doc/autoconf.texi (Special Shell Variables): Document some
19274 more LINENO gotchas, particularly with respect to the Awk+Sed hack.
19276 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): New macro.
19277 (_AS_LINENO_PREPARE): Use it instead of shell eval, since
19278 eval $LINENO is not portable in practice.
19280 2001-10-24 Akim Demaille <akim@epita.fr>
19282 * lib/Autom4te/General.pm (backname): New.
19284 2001-10-24 Akim Demaille <akim@epita.fr>
19286 * m4/: Remove, merged into...

19291 * doc/autoconf.texi (Shellology): Mention the problems with bash
19292 2.05's use of ANSI quoting in its `set' builtin.
19294 2001-10-22 Paul Eggert <eggert@twinsun.com>
19296 * lib/autoconf/functions.m4 (AC_FUNC_STRERROR_R):
19297 Rename ac_cv_func_strerror_r_works to ac_cv_func_strerror_r_char_p,
19298 and rename HAVE_WORKING_STRERROR_R to STRERROR_R_CHAR_P, since
19299 POSIX decided to standardize on the int flavor of strerror_r.
19300 Always do char* test, as there's no reason not to.
19301 Assign to a char* var, to catch strerror_r that returns int*.
19303 * doc/autoconf.texi (Particular Functions):
19304 Document the above changes. Also, document the fact that
19305 AC_FUNC_STRERROR_R defines HAVE_DECL_STRERROR_R.
19307 * NEWS: Mention HAVE_WORKING_STRERROR_R -> STRERROR_R_CHAR_P.
19309 2001-10-20 Akim Demaille <akim@epita.fr>
19311 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): The name of

19316 * lib/Autom4te/General.pm (&update_file): If destination is
19317 unchanged, remove the source.
19318 (&up_to_date_p): Don't be verbose, be debug.
19319 * bin/autoreconf.in: No longer support --m4dir.
19320 (&autoreconf): Display the full path of the configure.ac we are
19322 Trace it only once.
19323 Be sure to honor --force with gettextize.
19324 Always run aclocal.
19325 * doc/autoconf.texi: Adjust.
19327 2001-10-20 Akim Demaille <akim@epita.fr>
19329 * bin/autoheader.in ($localdir, $m4, $SIMPLE_BACKUP_SUFFIX):
19331 * bin/autoreconf.in (&autoreconf): Do not run gettextize when
19332 `intl' is already present, as it refuses unless --force.
19333 (&parse_args): Use -I, --include instead of the old Autoconf
19335 ($localdir, $autoconf_dir): Remove.
19337 (&maybe_autoreconf): New, to preserve $_ for File::Find.
19339 2001-10-19 Jens Petersen <petersen@redhat.com>
19341 * lib/autoconf/programs.m4 (AC_PROG_AWK): Prefer gawk to mawk.

19360 configure.ac being studied.
19362 2001-10-18 Paul Eggert <eggert@twinsun.com>
19364 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Cast sizeof to unsigned
19365 long, to work around a bug in the HP C compiler version HP92453-01
19368 * lib/m4sugar/m4sh.m4 (AS_DIRNAME): Use 'dirname' if that works.
19369 (AS_BASENAME_EXPR): New macro.
19370 (AS_BASENAME_SED): Do not assume GNU sed semantics.
19371 (AS_BASENAME): Use 'basename' if that works; then try 'expr';
19372 and fall back on 'sed' only if the other two fail. This makes
19373 AS_BASENAME act more like AS_DIRNAME.
19374 (as_me): Shell-quote the argument of AS_BASENAME, in case $0
19375 contains white space.
19376 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR):
19377 Use AS_DIRNAME, since I think it's now DOS-friendly.
19378 * tests/m4sh.at (DIRNAME_TEST): New arg $3.

19390 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N_PREPARE): m4_defun, not

19505 include handle the m4_pattern_*, no longer push the

19516 CONFIG_SHELL defaults to a shell that supports LINENO if available.
19518 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): If the current
19519 shell does not support LINENO, and if CONFIG_SHELL is unset or
19520 empty, and if we can find a shell that does support LINENO,
19521 then set CONFIG_SHELL to that shell and then re-execute
19522 ourselves with CONFIG_SHELL.
19524 2001-10-05 Paul Eggert <eggert@twinsun.com>
19526 * tests/Makefile.am (clean-local): Don't invoke $(TESTSUITE) if it
19527 doesn't exist. Remove *.tmp, as a .tmp file is created during the

19569 compatibility with POSIX shells.

19829 * lib/autotest/general.m4: Englishoes.
19830 From Tim Van Holder and Alexey Mahotkin.

19834 * doc/autoconf.texi (Common Shell Constructs): New node,
19835 documenting AS_DIRNAME.
19836 (Limitations of Usual Tools): Refer to it when discussing dirname.
19837 Also, update discussion of POSIX standard to reflect latest draft.
19839 * lib/autoconf/c.m4:
19840 (AC_LANG_INT_SAVE(C)): Also support negative values, down to LONG_MIN.
19842 * lib/autoconf/general.m4 (_AC_COMPUTE_INT_COMPILE):
19843 Do not pass a first argument with leading '-'
19844 to expr, by parenthesizing initial integers that might be negative.
19846 * doc/autoconf.texi (Particular Functions): AC_FUNC_GETPGRP
19847 now merely checks whether it is an error to pass an argument
19850 * lib/autoconf/functions.m4 (_AC_FUNC_GETPGRP_TEST): Remove.
19851 (AC_FUNC_GETPGRP): Don't bother with a runtime test. Just check
19852 whether it is a (compile-time) error to pass an argument to
19853 getpgrp. This simpler test supports the revised documentation,
19854 and is all that AC_FUNC_GETPGRP's users really need.
19856 2001-09-18 Akim Demaille <akim@epita.fr>
19858 * doc/autoconf.texi (Limitations of Make) <$<>: New.

19870 Add test for AS_BASENAME.
19871 * lib/m4sugar/m4sh.m4: Fix AS_BASENAME so that it passes the previous
19872 added test. It now correctly handles /1/2/3/, returning '3' not ''.
19873 Added AS_BASENAME_SED to make the interface the same as AS_DIRNAME.
19874 * tests/base.at: Fixed the expected responses. The old ones were
19876 * lib/autoconf/general.m4: Fixed AC_PREFIX_PROGRAM, it now behaves as
19877 the documentation claims it should (and how it behaved in 2.13).
19879 2001-09-18 Akim Demaille <akim@epita.fr>
19881 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): No INIT-CMDS in
19882 the AC_CONFIG_COMMANDS invocation.
19883 This also solves the name clash problems.
19884 Don't set the package's ID.
19885 * lib/m4sugar/Makefile.am (version.m4): Revamp.
19886 No longer to be shipped.
19887 (version.in): Remove.

19889 * lib/autoconf/status.m4: Adjust.
19890 Use `m4_PACKAGE_STRING'.
19891 * lib/autotest/general.m4 (AT_INIT): N-th signature change: now
19892 the only optional argument is the name of the test suite.
19893 Expect `package.m4' to define the package signature.
19894 * lib/autom4te.in (Autotest): Add `package.m4?'.
19895 * tests/Makefile.am (package.m4): New.
19896 * tests/suite.at: ifnames is a victim.
19898 2001-09-18 Akim Demaille <akim@epita.fr>

19901 AC_LIBSOURCE, AC_CONFIG_FILES.

19903 program version string doesn't match the package's.
19904 * lib/autoconf/general.m4 (AC_CACHE_VAL): Reestablish the space

19915 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):
19916 Always include <stdio.h> and <stdlib.h>. Evaluate
19917 the expression in an extra function before these includes. Call
19918 fprintf "%d" only after ensuring the argument is of type 'int'.
19919 Reported by Wayne Chapeskie <waynec@spinnaker.com>.
19921 2001-09-17 Paul Eggert <eggert@twinsun.com>
19923 Fix bug reported by Paul Townsend on AIX 4.3.3.0 with CFLAGS=-O4
19924 or CFLAGS=-O5. In that case, the linker has a relaxed view of
19925 fatal errors, and AC_CHECK_LIB causes it to include libraries even
19926 when they don't exist.
19928 * lib/autoconf/headers.m4 (AC_HEADER_DIRENT): Use AC_SEARCH_LIBS,
19929 not AC_CHECK_LIB, so that we don't use -ldir or -lx if we don't
19932 * lib/autoconf/specific.m4 (AC_ISC_POSIX): Replace the old, crufty
19933 version with the version used by fileutils 4.1, except use
19934 AC_SEARCH_LIBS, not AC_CHECK_LIB, so that we don't use -lcposix if
19937 * doc/autoconf.texi (AC_ISC_POSIX): Describe new behavior.

19977 2001-09-13 Akim Demaille <akim@epita.fr>
19979 * lib/autotest/general.m4 (AT_INIT): Create and remove
19980 `$as_me.[0-9]+' instead of `debug-[0-9]+.sh', so that multiple
19981 test suites can cohabit.
19983 2001-09-13 Akim Demaille <akim@epita.fr>
19985 * tests/mktests.sh: Don't output banners for empty test files.

20091 2001-09-05 Akim Demaille <akim@epita.fr>
20093 Be ready to handle filenames as stupid as `dnl.at', for if even
20094 the maintainer is dumb enough to do that...
20096 * lib/autotest/general.m4 (AT_SETUP, AT_LINE): Demonstrates your
20097 excellence in M4 quotation: consider `__file__' is active.

20277 find the executables for it.

20279 * tests/atlocal.in: Remove all the obscure envvar manipulations.
20281 * tests/atspecific.m4, tests/tools.at: Passing --localdir is
20282 indeed related to running the test suite, while passing

20286 * tests/autoscan: New.
20287 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): Don't

20306 2001-08-29 Akim Demaille <akim@epita.fr>

20713 * doc/autoconf.texi: Work around Texinfo buglets.
20714 (Transformation Rules): One example is enough, users are expected

20716 (dvar): New macro. Use it.
20718 2001-08-17 Akim Demaille <akim@epita.fr>
20720 * doc/autoconf.texi (Writing testsuite.at) <AT_CHECK>: Complete.

20773 autom4te.cache (it's a directory, not a file.
20774 * Makefile.am: Ditto (but maintainer-clean-local).
20776 2001-08-15 Akim Demaille <akim@epita.fr>
20778 * bin/autom4te.in (@m4_warning): New.
20779 (&handle_m4): Use it.
20780 * tests/m4sugar.at (m4_warn): Pass `-f' to autom4te to ensure the

20789 * tests/tools.at (autoupdating AC_PREREQ): Likewise.

20850 2001-08-11 Alexandre Duret-Lutz <duret_g@epita.fr>
20852 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Handle ACTION-IF-TRUE,
20853 ACTION-IF-FALSE, and ACTION-IF-UNKNOWN.
20854 * doc/autoconf.texi (C Compiler Characteristics): Update
20855 documentation for AC_C_BIGENDIAN.
20857 2001-08-11 Alexandre Duret-Lutz <duret_g@epita.fr>
20859 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Guess endianness by grep'ing
20860 magic values from an object file when cross-compiling.
20861 Based on code by Guido Draheim <Guido.Draheim@gmx.de>.
20863 2001-08-10 Akim Demaille <akim@epita.fr>
20865 * bin/autom4te.in (&handle_output): Don't use `grep' with side
20867 Suggested by Russ Allbery.
20869 2001-08-10 Ralf Corsepius <corsepiu@faw.uni-ulm.de>
20871 * lib/autoconf/general.m4 (_AC_OUTPUT_SUBDIRS): Propagate the
20872 current $prefix to the sub-configures.
20874 2001-08-09 Tim Van Holder <tim.van.holder@pandora.be>
20876 * lib/autoconf/lang.m4: Ignore *.xSYM when looking for an executable
20877 extension (needed on BeOS). Reported by Guido van Rossum.
20879 2001-08-09 Akim Demaille <akim@epita.fr>
20881 * bin/autom4te.in ($icache): Load it only if older than autom4te.
20883 2001-08-07 Akim Demaille <akim@epita.fr>
20885 * lib/autotest/general.m4 (AT_INIT): All the `at-*' are to be
20887 (at-setup-line): Huh? Be a variable `at_setup_line', not a file.
20888 No need to remove the files before and after the each test, before
20889 each test and at the end of the suite is enough.
20890 Display only the children `times', not the shell's.
20891 If the test failed or was skipped, at-times is not available.
20893 2001-08-07 Akim Demaille <akim@epita.fr>
20895 Always produce testsuite.log, including when there are no
20896 failures. This helps getting information on skipped tests, and
20897 duration of the tests. Err, implement the latter btw.
20899 * lib/autotest/general.m4 (AT_INIT): Set up fd 6 for the log.
20900 Dump information on the first run of each test.
20901 (AT_CLEANUP): Create `at-times' containing the duration of the
20904 2001-08-07 Akim Demaille <akim@epita.fr>
20906 The use of `dumpstat' revealed that `len' was used although it
20907 should not. m4_text_wrap was using it, but in the Autoconf world
20908 where it is legal. Hence (i) test M4sh in its own world, not
20909 Autoconf's, and (ii), ahem, fix the bug :)
20911 * lib/autotest/general.m4: Be sure the set good quotes, as tracing
20912 does not like `' instead of [].
20913 (AT_INIT): Forbid `^_?AT_'.
20914 And don't output such tokens.
20915 * tests/Makefile.am (CLEANFILES): Add `script', `script.s4g',
20916 `script.as', and `autom4te.cache'.
20917 Remove `empty' and `macro' which are no longer used.
20918 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): New.
20919 * tests/m4sugar.at: Use it.
20920 * lib/m4sugar/m4sugar.m4: Use `m4_len' not `len'.
20922 2001-08-07 Akim Demaille <akim@epita.fr>
20924 * bin/autoconf.in, bin/autoheader.in: --force, -f is a new option.
