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

346 * lib/autoconf/headers.m4 (AC_HEADER_STDBOOL): Drop gcc (and by

348 rather than merely testing for a compiler extension.

6984 not just when atconfig was located.
6986 Add 'testsuite -C dir'.
6987 * lib/autotest/general.m4 (_AT_ARG_OPTION): Move missing argument
6989 (AT_INIT) <PARSE_ARGS_END>: ...here, since -k always takes
6991 <DEFAULTS>: Delay computation of variables based on $at_dir...
6992 <PREPARE_TESTS>: ...to here, since -C can change $at_dir.
6993 <TESTS>: Re-invoke via absolute name, since -C may be in effect.
6994 <PARSE_ARGS>: Parse new option.
6995 <HELP_TUNING>: Document it.
6996 * tests/autotest.at (Choosing where testsuite is run): New test
6998 (Keywords and ranges): Add test for missing -k argument.
6999 * NEWS: Document this.

7005 build-aux/texinfo.tex: Sync from gnulib.
7006 * doc/fdl.texi, doc/make-stds.texi, doc/standards.texi:
7009 2008-01-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7011 * doc/autoconf.texi (Particular Programs): Do not mention the
7012 Autoconf version in which the AC_PROG_INSTALL change was done.
7013 Suggested by Paul Eggert.
7015 2008-01-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7017 Fix --help=recursive with multiple AC_CONFIG_SUBDIRS.
7018 * lib/autoconf/general.m4 (_AC_INIT_HELP): If, for recursive help
7019 mode, we change to the source directory, also set $ac_pwd so we
7020 do not go back to the build tree for the next config subdir.
7021 * tests/torture.at (Deep Package): Extend test to contain two
7022 config subdirs on the top level.
7024 Fix parallel `maintainer-check'.
7025 * Makefile.am (maintainer-check-tests): Depend on `all'.
7026 Use `$(MAKE) $(AM_MAKEFLAGS)' instead of plain `make'.
7027 * tests/Makefile.am (maintainer-check-c++, maintainer-check-posix):
7029 (maintainer-check): Serialize the testsuite runs.
7031 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE2): Accept `+'
7032 in feature string for --enable/--with. Convert to underscore
7035 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Require that
7036 `install -c file1 file2 dir' works.

7053 2008-01-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7055 * tests/Makefile.am (noinst_SCRIPTS): Renamed from
7056 check_SCRIPTS. Building the wrappers for `all' allows help2man
7057 to use them for the manpages.
7058 Report by Benoit Sigoure.
7060 * bin/autoreconf.in: Discard stderr for $autoconf/$aclocal --help.
7062 2007-12-16 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7064 Fix some write failure cases in Autotest.

7075 (_m4_defun_pro_outer, _m4_defun_epi, _m4_defun_epi_outer)
7076 (m4_require): Use m4_do, not m4_join.
7078 Fix some whitespace tests on cygwin.
7079 * tests/tools.at (autom4te and whitespace in file names): Restore
7080 font-lock. Create $TMPDIR before it might be used.
7082 Fix spurious testsuite failure with M4 1.4.11.
7083 * tests/local.at (AT_CHECK_M4): Cater to new m4 error message.
7085 Optimize AC_REQUIRE.
7086 * lib/m4sugar/m4sugar.m4 (m4_expansion_stack_push, _m4_defun_pro)
7087 (_m4_defun_pro_outer, _m4_defun_epi, _m4_defun_epi_outer)
7088 (m4_require): Avoid extra macro calls.
7090 2007-12-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7092 * tests/torture.at (srcdir): Fix quoting.
7094 Do not pass top_srcdir to configure scripts in testsuite.
7095 * tests/autotest.at (srcdir propagation): Copy install-sh to
7097 (my only test): Drop setting of `top_srcdir'.
7098 * tests/base.at (Input/Output): Likewise.
7099 * tests/local.at (AT_CONFIGURE_AC): Copy install-sh,
7100 config.guess, and config.sub to test source tree.
7101 Drop AC_CONFIG_AUX_DIR setting.
7102 (AT_CHECK_CONFIGURE): Drop setting of `top_srcdir'.
7103 * tests/torture.at (Substitute a 2000-byte string): Drop
7104 AC_CONFIG_AUX_DIR setting, copy install-sh to test source tree.
7105 (Substitute a newline, datarootdir workaround): Likewise.
7106 (Define a newline): Adjust for linenumber changes in configure.ac.
7107 * tests/foreign.at (Libtool): Adjust comment to reflect changes.
7109 * tests/semantics.at (AC_PATH_PROGS_FEATURE_CHECK): Skip test
7110 if `pwd` contains whitespace.
7112 Quote $abs_top_srcdir in tests.
7113 * tests/local.at (AT_CHECK_PERL_SYNTAX): Likewise.
7114 * tests/tools.at (Syntax of the shell scripts): Likewise.
7116 * tests/m4sh.at (LINENO): Quote $0.
7118 Fix testsuite program wrapper for whitespace in `pwd`.
7119 The problem here is that the usual mantra is that command
7120 variables can contain arguments, thus we cannot just escape
7121 $AUTOCONF, $AUTOM4TE etc. The compromise is to put the
7122 $top_builddir/tests directory early in $PATH, so that the
7123 wrappers are found by their plain name.
7124 * tests/wrapper.as: Put $testdir early in $PATH.
7125 (AUTOCONF, AUTOHEADER, AUTOM4TE): Set to plain command names.
7127 Proper config.status --file/--header and $srcdir escaping.
7128 * lib/autoconf/status.m4 (_AC_OUTPUT_MAIN_LOOP): Quote special
7129 characters in $ac_file_inputs.
7130 (_AC_OUTPUT_FILE, _AC_OUTPUT_HEADER): eval $ac_file_inputs
7132 * tests/torture.at (datarootdir workaround): Adjust.
7133 (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS): Extend test.
7135 Fix Autotest for whitespace in `pwd`.
7136 * lib/autotest/general.m4 (AT_INIT)
7137 <at_func_create_debugging_script, Driver Loop>:
7138 Quote $at_group_dir.
7139 * tests/autotest.at (whitespace in absolute testdir): New test.
7141 * lib/autom4te.in: Quote @datadir@.
7143 Proper file name escaping in Autoconf programs and Perl modules.
7144 This includes escaping of characters special to the shell
7145 as well as special to Perl, e.g., leading `<' or `>'.
7146 For example, when $file starts with `>', `open ">$file"'
7147 wrongly tries to append to a different file.
7148 * bin/autoconf.as: Fix quoting for autom4te options.
7149 * lib/Autom4te/General.pm (shell_quote): New function, taken
7150 from coreutils, written by Jim Meyering.
7152 * bin/autom4te.in (files_to_options, handle_m4): Use shell_quote
7154 * bin/autoreconf.in (parse_args): Likewise.

7158 * bin/ifnames.in: Likewise, XFile usage fixes.
7159 * tests/tools.at (autom4te and whitespace in file names): Extend
7160 test. Test twice, with special characters allowed on w32, and the
7161 rest. Test leading and trailing whitespace, for `open_quote'.
7162 (autotools and whitespace in file names): New, analogous test.
7163 Reported by Paul Eggert and Benoit Sigoure, additional suggestions
7164 by Russ Allbery and Eric Blake.
7167 * lib/Autom4te/Channels.pm, lib/Autom4te/Configure_ac.pm,
7168 lib/Autom4te/Struct.pm, lib/Autom4te/XFile.pm: Likewise.
7169 * lib/Autom4te/FileUtils.pm (open_quote): New function.
7170 (update_file, contents): Use it.
7172 * Makefile.am (autom4te-update): Rewrite for git.
7174 2007-12-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7176 * doc/autoconf.texi (autom4te Invocation, Autom4te Cache): Fix typos.
7178 Fix copyright years.
7179 * Makefile.am, doc/install.texi, lib/autoconf/fortran.m4,
7180 lib/autoconf/lang.m4, lib/freeze.mk: Likewise.
7182 2007-12-04 Eric Blake <ebb9@byu.net>
7184 Manually resync with gnulib, since 'make cvs-update' no longer works.

7190 * doc/Makefile.am (TEXINFO_TEX): Add.
7192 2007-11-27 Paul Eggert <eggert@cs.ucla.edu>
7194 Fix AC_C_BIGENDIAN bug caused by new awk method of substitution.
7195 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Don't comment out the
7196 #undef as this runs afoul of our new way of creating config.h.
7197 Problem reported by Jim Meyering in
7198 <http://lists.gnu.org/archive/html/autoconf-patches/2007-11/msg00164.html>.

7202 Fix autom4te for unusual characters in input file names.
7203 * bin/autom4te.in (files_to_options): Quote active characters
7205 * tests/tools.at (autom4te and white space in file names):
7208 * doc/autoconf.texi (Limitations of Usual Tools) <awk>:
7209 Document that Tru64 awk always splits $0.
7211 2007-11-24 Stepan Kasal <kasal@ucw.cz>
7213 * lib/autotest/general.m4 (AT_INIT): Do not extract the
7214 `#AT_STOP_...' line at the end of each test.
7216 2007-11-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7218 * lib/autotest/general.m4 (AT_INIT): For awk line number
7219 extraction script, ensure `$at_group' has a defined value
7220 even for the empty set, and properly quote its usage inside
7223 2007-11-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7225 * doc/autoconf.texi (Shell Functions): New chapter. Document
7226 IRIX sh $0 issue in functions, move content from ...
7227 (Portable Shell): ... here.
7228 (Shell Script Compiler): Note that shell functions are not
7229 totally unportable any more.
7231 2007-11-22 Stepan Kasal <kasal@ucw.cz>
7232 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

7242 2007-11-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7244 Fix IRIX testsuite debugging failures: $0 in functions.
7245 * lib/autotest/general.m4 (AT_INIT) <at_func_create_debugging_script>:
7246 Do not use $0 inside a function, as IRIX sh will set that to the
7247 function name rather than the script invocation name.
7249 2007-11-19 Paolo Bonzini <bonzini@gnu.org>
7250 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7252 * lib/autotest/general.m4 (at_func_test): Use cached line numbers
7253 to extract test scripts.
7254 (AT_INIT): Extract and cache test script line numbers.
7256 2007-11-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7258 * lib/autotest/general.m4: Revert 2007-11-15 patch and
7259 subsequent fixups; the awk -> here-document conversion trashes
7260 performance too much with AIX sh.
7262 2007-11-18 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7264 * tests/local.at: Do not test m4, perl with AT_TESTED.
7266 Diagnose and guard against write errors dealing with config.status.
7267 The general idea is this: all write failures from `configure'
7268 writing `config.status' are indicated by $ac_write_error, which
7269 is only checked at the end. This is safe because config.status
7270 code is not executed before the file is complete. Other write
7271 failures, be they inside config.status, or in sub shell/awk
7272 scripts spawned from configure or config.status, typically need
7273 earlier checking, as their results are used right afterwards.
7274 * lib/autoconf/status.m4 (AC_OUTPUT): Initialize `ac_write_fail'
7275 before writing config.status, check afterwards.
7276 (_AC_OUTPUT_FILES_PREPARE, _AC_OUTPUT_FILE)
7277 (_AC_OUTPUT_HEADERS_PREPARE,_AC_OUTPUT_CONFIG_STATUS):
7278 Set `ac_write_error' for write failures to config.status. Barf
7279 upon write failures to temporary files.
7280 Adjust note about closing and reopening the here-document.
7281 (_AC_OUTPUT_HEADER, _AC_OUTPUT_LINK, _AC_OUTPUT_COMMAND)
7282 (_AC_OUTPUT_MAIN_LOOP): Likewise, adjust note about closing and
7283 reopening the here-document.
7284 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
7285 Ensure `ac_write_error' does not escape into config.status.
7286 Also, add a couple of code paths not yet exercised in the test
7287 suite: a config file with input from stdin, and a config header
7289 Suggestion for catching write errors by Bruno Haible.
7291 2007-11-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7293 Avoid error with Tru64 awk and testsuite lines with many words.
7294 * lib/autotest/general.m4 (AT_INIT): In the awk script that
7295 reads the testsuite, set the field separator to an unusual value,
7296 in order to not run over the limit of 199 fields. Tru64 4.0D awk
7297 even splits the input if $i, i>0, was never accessed in the script.
7299 Revert 2007-10-17 change.
7300 * TODO: Multiline args in config files and headers mean something
7301 different and are not fixed, see

7375 * lib/autoconf/types.m4 (_AC_TYPE_LONG_LONG_SNIPPET):
7376 Do not check for preprocessor flaws.
7378 2007-11-13 Jim Meyering <meyering@redhat.com>
7380 Adapt dependencies, now that a version change doesn't modify configure.ac

7405 Add -v option to autoreconf invocation.
7407 Remove the autoreconf-provided INSTALL, so that we regenerate it.
7408 * GNUmakefile (dummy): Remove INSTALL.
7410 Remove racy commands to build scripts in bin/ and tests/.
7411 * man/Makefile.am (.x.1): Now that scripts in bin/ and tests/
7412 are guaranteed to be built, remove the rules that tried to build
7413 them. Before, with a parallel build, these rules could lead to
7414 two processes writing tests/wrapper.in concurrently.

7417 * Makefile.am (SUBDIRS): The man-page-creation process runs $(MAKE)

7470 ($(TESTSUITE)): Depend on just-built package.m4, not the one
7472 When running $(AUTOTEST), search "." before searching $(srcdir).
7474 Avoid a race condition that would make parallel "distclean" fail.
7475 * tests/Makefile.am (distclean-generic): Replace the default,
7476 automake-provided rule with an identical one, but with an additional
7477 dependency on distclean-local. Simply adding the dependency would
7478 cause automake not to emit the rule at all.
7479 * BUGS: Building with -jN works, now.
7481 Distribute git-version-gen.
7482 * Makefile.am (EXTRA_DIST): Add build-aux/git-version-gen,
7483 since GNUmakefile is distributed, and requires it for dist* rules.
7485 Remove two more generated files from version control.
7486 * INSTALL: Remove generated file.
7487 * lib/autoscan/autoscan.list: Remove generated file.
7489 2007-11-09 Paul Eggert <eggert@cs.ucla.edu>
7491 * GNUmakefile (PATH): Remove stray apostrophes; they become
7492 part of PATH, which isn't wanted here.
7494 2007-11-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7496 New config files output variable `top_build_prefix'.
7497 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Substitute
7499 * doc/autoconf.texi (Preset Output Variables): Document it.
7501 Report by Bob Friesenhahn.
7503 Avoid expr for arithmetic evaluation if the shell accepts $((...)).
7504 * lib/autotest/general.m4 (AT_INIT) <at_func_arith>: New
7505 function, to parametrize arithmetic with expr vs. the shell.
7506 Use it where possible.
7507 Suggestion by Benoit Sigoure.
7509 2007-11-03 Benoit Sigoure <tsuna@lrde.epita.fr>
7511 Adjust the documentation of autotest WRT atlocal.
7512 * doc/autoconf.texi (Making testsuite Scripts): It is not necessary,
7513 when using Automake, to write a rule to produce atlocal, since it's
7514 an AC_CONFIG_FILES. Mention that atlocal.in needs to be
7515 distributed, not atconfig.in.
7517 2007-11-04 Eric Blake <ebb9@byu.net>
7519 Update list information.
7520 * README: Mention new autoconf-commit list.

7529 * build-aux/.gitignore: Ignore mkinstalldirs.
7531 * doc/autoconf.texi (autoreconf Invocation): Fix an underfull line.
7533 2007-11-03 Jim Meyering <meyering@redhat.com>
7535 s/-/./ in snapshot version string: 2.61a-256-8b556 -> 2.61a.256-8b556
7536 * build-aux/git-version-gen: This syncs from coreutils.
7538 Adjust the build procedure so "make check" works reliably.
7539 * README-hacking: Include an extra step between "make" and
7540 "make check" to ensure that the latter passes.
7542 Use just-built tools, when possible.
7543 * GNUmakefile (PATH): Set and export here, ...
7544 (dummy): ... rather than here.
7546 2007-11-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7547 and Andreas Schwab <schwab@suse.de>
7549 * tests/Makefile.am ($(srcdir)/package.m4): Work around bash
7552 2007-11-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7554 * configure.ac (AC_PREREQ): Require version 2.60, for
7555 AC_PROG_SED, AC_PROG_GREP.

7569 Support m4 1.4.5 in testsuite.
7570 * tests/torture.at (Define a newline): Exclude line numbers in
7572 Reported by Ralf Wildenhues.
7574 2007-11-03 Jim Meyering <meyering@redhat.com>
7576 Remove automake-provided files from version control.

7579 * build-aux/missing: Remove file.
7580 * build-aux/mdate-sh: Remove file.
7581 * build-aux/.gitignore: New file.
7582 Suggestion from Ralf Wildenhues.
7584 2007-11-03 Eric Blake <ebb9@byu.net>
7586 Adjust version comparison to account for git snapshot numbers.
7587 * lib/m4sugar/m4sugar.m4 (_m4_version_unletter): Also treat - as a

7596 extracted from AC_TYPE_LONG_LONG_INT and AC_TYPE_UNSIGNED_LONG_LONG_INT.
7597 (AC_TYPE_LONG_LONG_INT, AC_TYPE_UNSIGNED_LONG_LONG_INT): Use it.
7598 Fixes problem with Sun C 5.[0-8] in 32-bit mode, reported in
7599 <http://lists.gnu.org/archive/html/autoconf-patches/2007-10/msg00210.html>
7600 Suggested by Paul Eggert.
7602 2007-10-28 Jim Meyering <meyering@redhat.com>
7604 * README-hacking: Autoconf, Automake, and Perl are required to build.
7605 List Gzip and Tar separately. Suggested by Ralf Wildenhues.
7607 2007-10-28 Jim Meyering <meyering@redhat.com>
7609 README-hacking: Recommend running autoreconf -vi.
7610 * GNUmakefile (dummy): Use autoreconf -i, with appropriate PATH,
7611 so that we use just-built tools when they're available.
7612 Suggestions from Ralf Wildenhues.
7614 2007-10-28 Jim Meyering <meyering@redhat.com>
7616 Make inter-release --version output more useful.
7618 Now, each unofficial build has a version "number" like 2.61a-19-58dd,
7619 which indicates that it is built using the 19th change set
7620 (in _some_ repository) following the "v2.61a" tag, and that 58dd
7621 is a prefix of the commit SHA1.
7622 * build-aux/git-version-gen: New file.
7623 * configure.ac: Run it to set the version.
7624 (AM_INIT_AUTOMAKE): Don't check NEWS here.
7625 * Makefile.am (dist-hook): Arrange so that .version appears only
7626 in distribution tarballs, never in a checked-out repository.
7627 * .gitignore: Add .version here, too. Just in case.
7628 * tests/Makefile.am ($(srcdir)/package.m4): Depend on Makefile,
7629 not configure.ac, now that the version number changes automatically.
7631 Ensure that $(VERSION) is up to date for dist-related targets.
7632 * GNUmakefile: Arrange to rerun autoconf, if the version reported by
7633 git-version-gen doesn't match $(VERSION), but only for dist targets.
7635 2007-10-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

7664 and Eric Blake <ebb9@byu.net>
7666 * lib/autoconf/c.m4 (AC_C_RESTRICT): Work around Sun C++ compatibility
7667 problem reported by Bruno Haible in
7668 <http://lists.gnu.org/archive/html/bug-autoconf/2007-10/msg00027.html>.

7672 * doc/autoconf.texi (Particular Types): Mention bug in HP-UX 11.00
7675 2007-10-22 Paul Eggert <eggert@cs.ucla.edu>
7677 Don't check for bug in HP-UX 11.00 cpp.
7678 * lib/autoconf/types.m4 (AC_TYPE_UNSIGNED_LONG_LONG_INT):
7679 Use -1ull rather than -1u, since that causes problems with gnulib; see
7680 <http://lists.gnu.org/archive/html/bug-gnulib/2007-10/msg00329.html>.

7698 escaping of backslash in here-documents.
7700 Fix `Deep Package' test failure on FreeBSD.
7701 * tests/torture.at (Deep Package): Do not add `.' to $PATH
7702 unnecessarily. Do not try running `/bin/sh configure' with a
7703 configure script to be found in $PATH, if the shell does not do
7704 this resolution. Fixes test failure on FreeBSD.
7706 Fix config header generation with AIX awk.
7707 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS_PREPARE): In awk
7708 script, use helper array D_is_set, as `" 0"' does not evaluate
7709 to true for AIX awk.

7750 array of banner text from a special diversion.
7751 <PARSE_ARGS_END>: No longer need awk to find banners.
7752 <TESTS>: Banners are no longer processed by main driver loop, so
7753 we no longer need case statement.

7852 use $as_myself, not $0.
7853 (_AC_INIT_HELP): For --help=recursive, if the subdir does not

7855 that the subpackage configure script is capable of running
7856 --help=recursive in the source tree.

8930 Document the restrictions on AC_CHECK_ALIGNOF's type argument.
8931 * lib/autoconf/types.m4 (_AC_CHECK_TYPE_NEW):
8932 For C, just try sizeof (TYPE) and sizeof ((TYPE)); if the former
8933 works but the latter doesn't, then it's a valid type.
8934 This lets people use function types and so forth.
8935 For C++ there doesn't seem to be a simple solution, so leave it alone.
8936 (AC_CHECK_SIZEOF): Allow argument to be a variable.
8937 (AC_CHECK_SIZEOF, AC_CHECK_ALIGNOF): Don't bother to invoke

9001 * doc/autoconf.texi (Specifying Names): `--host' does not
9002 change the build type.
9004 2007-03-05 Paul Eggert <eggert@cs.ucla.edu>

9108 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Also
9109 AC_SUBST([MKDIR_P]), so that Automake < 1.10 will pick up its
9110 trace, if a package uses AC_PROG_MKDIR_P explicitly. The actual
9111 substitution will still be done by the special code.

9131 * doc/autoconf.texi: Direntry for "autoconf Invocation" renamed.
9133 2007-01-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9135 * lib/autoconf/programs.m4 (AC_PROG_SED): When closing a pipe
9136 early on the reader side, drop stderr of the input to avoid
9137 `broken pipe' error output; this may happen even with shell
9138 builtin `echo' of some bash versions. Reports by Ian Macdonald
9139 <iamacdo@telkomsa.net> and Sam Sexton <Sam.Sexton@reuters.com>.
9141 2007-01-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9143 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Use newlines to

9154 http://lists.gnu.org/archive/html/autoconf-patches/2007-01/msg00077.html
9155 * doc/autoconf.texi (Signed Overflow Examples): Give more
9156 discussion about the allow_superuser_privileges example,
9157 and change it a bit to make things clearer.
9158 (Optimization and Wraparound): Clarify whether the compiler
9159 will generate an infinite loop for the example derived from
9160 Autoconf's mktime test.
9161 (Signed Overflow Advice): Say that -ftrapv is meant for debugging.
9162 Also, clarify unsigned multiplication overflow.
9164 2007-01-04 Eric Blake <ebb9@byu.net>
9166 * bin/Makefile.am (RELEASE_YEAR): New macro.
9167 (edit): Use it to supply correct copyright year to scripts.
9168 * bin/autoconf.as (version): Use it.
9169 * bin/autoheader.in ($version): Likewise.
9170 * bin/autom4te.in ($version): Likewise.
9171 * bin/autoreconf.in ($version): Likewise.
9172 * bin/autoscan.in ($version): Likewise.

9176 2007-01-02 Paul Eggert <eggert@cs.ucla.edu>
9178 * doc/autoconf.texi (Integer Overflow): Revised based on today's
9179 feedback. The most important changes document what happens when
9180 you convert an out-of-range value to a signed integer type, and
9181 say that (sum < a) != (b < 0) reliably detects overflow when sum =
9184 * doc/autoconf.texi (Integer Overflow): Greatly expand and
9185 rewrite, taking notions from the recent discussion on the gcc and
9186 autoconf mailing lists; please see
9187 http://lists.gnu.org/archive/html/autoconf-patches/2006-12/msg00091.html
9188 and follow the many links.
9189 (Integer Overflow Basics, Signed Overflow Examples):
9190 (Optimization and Wraparound, Signed Overflow Advice):
9191 (Signed Integer Division): New sections.
9193 2006-12-28 Steven G. Johnson <stevenj@alum.mit.edu>
9195 * lib/autoconf/general.m4 (AC_DEFINE_TRACE): Don't include
9196 preprocessor macro arguments in traced name.
9197 * doc/autoconf.texi (Defining symbols): Document longstanding
9198 support for AC_DEFINE-ing macros with arguments, and document
9199 behavior when the same variable has multiple AC_DEFINEs.
9200 * lib/autoconf/fortran.m4 (_AC_FC_WRAPPERS): Revert to the
9201 old implementation which AC_DEFINEs the FC_FUNC and FC_FUNC_
9202 macros directly, giving much shorter and simpler code.
9204 2006-12-28 Malcolm Purvis <malcolmp@xemacs.org> (trivial change)
9206 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Insert a
9207 space before "$ac_configure_args" to prevent a 'config.status
9208 --recheck' failure if ac_configure_args doesn't contain a leading
9209 space. This works around a problem with the XEmacs configure.ac,
9210 which uses the (undocumented) ac_configure_args variable
9211 inconsistently with Autoconf.
9213 2006-12-22 Paul Eggert <eggert@cs.ucla.edu>
9215 * lib/autoconf/functions.m4 (AC_FUNC_MKTIME):
9216 Include <limits.h>, and use its INT_MAX to rewrite the
9217 j loop so that it does not overflow 'int'. Problem reported by
9219 <http://lists.gnu.org/archive/html/bug-gnulib/2006-12/msg00084.html>.
9220 Play it safe by shifting left by 1 rather than multiplying by 2,
9221 as GCC is less likely to optimize this away when the value
9222 is signed (when it assumes overflow leads to undefined behavior).
9223 Also, don't assume time_t uses two's complement.
9225 2006-12-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9227 * tests/torture.at (Substitute a 2000-byte string): Avoid using
9228 a 10kB long (multi-line) string literal, OpenServer 5.0.7 ksh
9229 dumps core on it. Report by Tim Rice.
9231 2006-12-18 Steven G. Johnson <stevenj@alum.mit.edu>
9233 * lib/autoconf/general.m4 (AC_ARG_ENABLE): Print help about
9234 --disable-option-checking to --help output even when
9235 AC_PRESERVE_HELP_ORDER is not used.
9236 (_AC_INIT_PARSE_ENABLE2): Print warnings using actual --enable or
9237 --with argument, rather than argument with [-.] replaced by
9239 * NEWS: Fix typo in previous change; the news was in the
9242 2006-12-18 Paul Eggert <eggert@cs.ucla.edu>
9244 * NEWS: Warnings are now generated by default for unknown
9245 --enable-* and --with-* options.
9246 * doc/autoconf.texi (Option Checking): Renamed from
9247 (Configure Option Checking). Tighten up the wording a bit.
9248 (External Software, Package Options): Cross-reference to Option
9249 Checking, and use this to shorten our section.
9250 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Prefer test -n
9251 "$x" to test "x$foo" != x.
9252 * lib/autoconf/status.m4 (AC_OUTPUT): Likewise.
9253 Don't warn if $enable_option_checking is "no".
9254 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Initialize
9255 ac_unrecognized_opts to the empty string.
9256 Don't echo the unrecognized opts, as this might mishandle
9257 backslashes or leading -.
9258 (AC_PRESERVE_HELP_ORDER): Put the --disable-option-checking
9259 usage next to the other --disable-FEATURE options in the
9262 2006-12-18 Steven G. Johnson <stevenj@alum.mit.edu>
9264 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS, _AC_INIT_PARSE_ARGS):
9265 (_AC_INIT_PARSE_ENABLE2, _AC_INIT_HELP, _AC_ENABLE_IF):
9266 Print warning for unrecognized --with and --enable options
9267 (AC_DISABLE_OPTION_CHECKING): New macro to disable warnings.
9268 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS, _AC_OUTPUT_SUBDIRS):
9269 Disable option checking when subdirs are configured.
9270 (AC_OUTPUT): If warnings are enabled, print warning about
9271 unrecognized --with and --enable options at the end of
9272 the configure output (as well as at the beginning).
9273 * doc/autoconf.texi (Option Checking): New node.
9274 Document new option warning functionality.
9276 2006-12-16 Eric Blake <ebb9@byu.net>
9278 * configure.ac (AC_INIT): Bump version, since 2.61a is released.
9279 * NEWS: Start news for current version.
9281 2006-12-15 Paul Eggert <eggert@cs.ucla.edu>
9283 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT):
9284 Define HAVE_GETMNTENT to 1, not to the empty string.
9285 Problem originally reported by Jochen Friedrich in
9286 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=403243>.
9288 This change prompted by a problem report by Andrey Simonenko in
9289 <http://lists.gnu.org/archive/html/bug-autoconf/2006-12/msg00026.html>.
9290 * doc/autoconf.texi (Defining Symbols): AC_DEFINE works for
9291 object-like macros only, in the traditional portable character
9293 * lib/autoconf/general.m4 (AC_DEFINE_TRACE_LITERAL):
9294 Warn about attempts to define things that are not identifiers.
9295 * lib/autoconf/fortran.m4 (_AC_FC_WRAPPERS): Rewrite to avoid
9296 awful hack that AC_DEFINEd macro names containing parentheses.
9298 2006-12-12 Paul Eggert <eggert@cs.ucla.edu>
9300 * doc/autoconf.texi: Undo some of the 2006-12-10 change. It was
9301 too drastic, even if Texinfo in theory requires it for info mode.
9303 (config.status Invocation): Renamed back from Recreating a
9305 (Obsolete config.status Use): Renamed back from Obsolete Recreation.
9306 (Autoconf 2.13): Renamed back from 20th-century Autoconf 2.
9308 2006-12-11 Paul Eggert <eggert@cs.ucla.edu>
9310 * NEWS: Version 2.61a.
9312 2006-12-11 Paul Eggert <eggert@cs.ucla.edu>
9313 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9315 * NEWS: Document changes with echo and printf, and the lack
9316 of limits on the total size of multi-line values of substituted
9317 variables, and the AC_FUNC_FSEEKO fix.
9319 2006-12-10 Paul Eggert <eggert@cs.ucla.edu>
9321 * doc/autoconf.texi (Writing Autoconf Input): Renamed from
9322 Writing configure.ac.
9323 (Autoconf Input Layout): Renamed from configure.ac Layout.
9324 (Recreating a Configuration): Renamed from config.status Invocation.
9325 (Obsolete Recreation): Renamed from Obsolete config.status Use.
9326 (acconfig Header): Renamed from acconfig.h.
9327 (20th-century Autoconf 2): Renamed from Autoconf 2.13.
9328 (Writing Testsuites): Renamed from Writing testsuite.at.
9329 (Autom4te Cache): Renamed from autom4te.cache.
9331 * BUGS: Remove mention of VPATH problem, since it's now documented
9332 not to be a bug in the Autoconf build procedure itself, but rather
9333 a problem with the proprietary `make' programs.
9335 * doc/autoconf.texi (Build Directories): Add a cross reference
9338 * build-aux/config.guess, build-aux/config.sub, build-aux/texinfo.tex:
9339 * doc/standards.texi: Sync from gnulib.
9341 * man/autoconf.1, man/autoheader.1, man/autom4te.1, man/autoreconf.1:
9342 * man/autoscan.1, man/autoupdate.1, man/config.guess.1:
9343 * man/config.sub.1, man/ifnames.1: Remove from CVS, since they're
9344 generated automatically.
9346 2006-12-06 Paul Eggert <eggert@cs.ucla.edu>
9348 * lib/autoconf/c.m4 (_AC_PROG_CC_C89): Also try -xc99=all, for Sun
9349 C 5.8 on Solaris 10. Using -xc99=all rather than -xc99 bypasses
9350 the buggy -xc99 option of Forte Developer 7 C on Solaris 9.
9352 2006-12-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9354 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Drop the
9355 `CEOF$ac_eof' special marker, the awk script cannot contain a
9356 line matching `^CEOF', so this is not needed any more.
9357 * tests/torture.at (Substitute a newline): Expose the `%!_!# '
9358 special marker in the test.
9360 2006-12-06 Stepan Kasal <kasal@ucw.cz>
9362 * tests/tools.at (autom4te preselections): Use `find -newer';
9363 remove one of the sleeps.
9365 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE): Make it
9366 more readable, using ...
9367 (_AC_INIT_PARSE_ENABLE2): ... this new helper macro.
9369 * doc/autoconf.texi (autoheader Invocation): Do not double-
9370 quote the parameter of `AH_BOTTOM' in the example.
9372 2006-12-05 Stepan Kasal <kasal@ucw.cz>
9374 * doc/autoconf.texi (Configuration Headers): Remove the
9375 example with multiple input files.
9376 (autoheader Invocation): Encourage `AH_BOTTOM', discouraging
9377 multiple input files.
9379 2006-12-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9381 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): When
9382 creating the awk substitution script, handle one input line at a
9383 time, so that the maximum length of a substituted (multi-line)
9384 value is not limited by the size of the sed pattern space.
9385 The trade-off is a slightly repetitive sed script.
9386 * doc/autoconf.texi (Limitations of Usual Tools): Branch labels
9387 can only have up to 7 characters, due to Solaris 10 /bin/sed.
9388 * tests/torture.at (Substitute a 2000-byte string): Increase the
9389 test with several long lines, they should not be caught by sed
9392 * tests/tools.at (autom4te preselections): New test, to flag
9393 entries missing from autom4te.cfg.
9394 Report by David Byron <dbyron@hheld.com>.
9396 * tests/torture.at (Substitute a 2000-byte string): Actually use
9397 AC_PROG_AWK, so the last change works as intended.
9398 (Substitute and define special characters): Likewise.
9399 (Substitute a newline): Likewise.
9401 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Use `$AWK'
9402 instead of `awk' consistently.
9403 (_AC_OUTPUT_CONFIG_STATUS): Initialize $AWK.
9404 * tests/torture.at (Torturing config.status): Test both the
9405 result of AC_PROG_AWK and plain awk.
9406 (Substitute a 2000-byte string): Likewise.
9407 (Substitute and define special characters): Likewise.
9408 (Substitute a newline): Likewise.
9410 2006-12-04 Paul Eggert <eggert@cs.ucla.edu>
9412 * lib/autoconf/functions.m4 (AC_FUNC_FSEEKO): Check that fseeko
9413 can be assigned to a function pointer. Problem reported by
9414 Peter Palfrader in <http://bugs.debian.org/401377>. Based on
9415 part of a patch by Ralf Wildenhues in that same bug report.
9417 2006-12-01 Paul Eggert <eggert@cs.ucla.edu>
9419 * tests/mktests.sh (ac_exclude_list): Exclude AC_FUNC_SETVBUF_REVERSED.
9420 * tests/semantics.at (AC_FUNC_SETVBUF_REVERSED): New test.
9422 2006-12-01 Eric Blake <ebb9@byu.net>
9424 * lib/autoconf/c.m4 (AC_LANG_INT_SAVE): Avoid newline, to aid in
9425 cross-compiling from cygwin to mingw.
9426 Reported by Bob Rossi. This resurrects the 2000-11-30 patch to
9427 aclang.m4, which was mistakenly removed in the 2001-09-17 patch
9428 to lib/autoconf/c.m4.
9430 2006-12-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9432 * lib/m4sugar/m4sh.m4 (_AS_ECHO_PREPARE): Use a longer test
9433 string for more reliable failure. Wrap the entire test that
9434 causes the broken Solaris printf to dump core, in a subshell,
9435 so the segmentation fault message is reliably suppressed.
9436 Fix shell expansion errors by using /usr/ucb/echo always;
9437 avoid an error on systems without it by another subshell.
9438 Avoid m4 expansion of `$1'. Set the zeroth argument of the
9439 subshell-$as_echo to `as_echo', for better error message.
9441 2006-11-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9443 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): If `BASH_ARGV' or
9444 `BASH_SOURCE' contain a newline, set them to empty, as they may
9447 2006-11-27 Paul Eggert <eggert@cs.ucla.edu>
9449 Turn AC_FUNC_SETVBUF_REVERSED into a noop. It's been obsolete for
9450 years and is too hard to maintain now. The last straw was
9451 reported by Jerker Baeck in
9452 <http://lists.gnu.org/archive/html/autoconf/2006-11/msg00102.html>.
9453 * NEWS: AC_FUNC_SETVBUF_REVERSED is now obsolete.
9454 * doc/autoconf.texi (Particular Functions): Move
9455 AC_FUNC_SETVBUF_REVERSED from here...
9456 (Obsolete Macros): ... to here. Say that it does nothing now.
9457 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
9458 Turn into (almost) a no-op.
9460 * lib/autoconf/c.m4 (AC_PROG_GCC_TRADITIONAL, AC_C_CONST):
9462 Do not recommend via AN_FUNCTION, AN_IDENTIFIER, or AN_HEADER.
9463 These macros are obsolescent and new applications shouldn't need them.
9464 * lib/autoconf/functions.m4 (AC_FUNC_CLOSEDIR_VOID, AC_REPLACE_FNMATCH):
9465 (AC_FUNC_GETLOADAVG, AC_FUNC_GETPGRP, AC_FUNC_MEMCMP):

9471 * lib/autoconf/types.m4 (AC_STRUCT_TM): Likewise.
9473 * doc/autoconf.texi (Setting Output Variables): Mention that
9474 @VAR1@VAR2 has unspecified behavior. Problem reported by
9476 * NEWS: Mention this.
9478 * Makefile.am: Put only a single '#' into the copyright notice,
9479 so that it's also present in the output file. Standardize wording
9480 in makefile copyright notices to match GNU coding standards.

9494 2006-11-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9496 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Fix error
9497 in the sed script that mangles the awk script: delete up to the
9498 first exclamation mark only.
9499 * tests/torture.at (Substitute and define special characters):
9502 2006-11-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9504 Rewrite config files generation: avoid quadratic growth in
9505 the number of substituted variables by using awk instead of sed
9506 for the bulk of the substitutions.
9507 * NEWS: Mention this.
9508 * doc/autoconf.texi (Setting Output Variables): `|#_!!_#|' is also
9509 forbidden in the output (and thus input) file.
9510 * lib/autoconf/status.m4 (_AC_AWK_LITERAL_LIMIT): New macro.
9511 (_AC_OUTPUT_FILES_PREPARE): Instead of several sed scripts,
9512 generate just one large awk script for substitutions,
9513 eliminating much of the earlier complexity, while adding some
9514 new complexity. Only expand the substitution templates at
9515 configure time, for smaller configure script size. If
9516 _AC_SUBST_FILES are used, test 'awk' for working getline support
9517 at config.status time. If absent, interpolate through the
9518 shell. The awk script was written with much help
9519 from Paolo Bonzini and Paul Eggert.
9520 (_AC_SED_CMD_NUM, _AC_SED_DELIM_NUM, _AC_SED_FRAG): Removed.
9521 (_AC_SED_FRAG_NUM): Likewise.

9524 (_AC_OUTPUT_FILE): Use _AC_SUBST_CMDS.
9525 * tests/torture.at (Substitute a 2000-byte string): Also
9526 substitute a line with 1000 words, and a variable with several
9528 (Substitute and define special characters): Test awk special
9529 characters, and put substitution input strings `@foo@' in the
9530 output, to test that no recursion happens; test several other
9531 combinations from Paolo Bonzini.
9533 2006-11-25 Paul Eggert <eggert@cs.ucla.edu>
9535 * lib/autotest/general.m4 (AT_INIT): Undo recent changes
9536 that replaced echo with AS_ECHO where this wasn't necessary.
9537 Problem reportd by Ralf Wildenhues.
9538 * lib/m4sugar/m4sh.m4 (_AS_ECHO_PREPARE): Port to Solaris 7,
9539 where "/usr/bin/printf '%s\n' S" dumps core if S is long.
9540 This is Sun bug 4206210. Problem reportd by Ralf Wildenhues.
9542 2006-11-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9544 * lib/freeze.mk (GREP): Removed, no need to initialize this.
9546 2006-11-21 Paul Eggert <eggert@cs.ucla.edu>
9548 * doc/autoconf.texi (Limitations of Usual Tools): Don't claim
9549 that traditional Awk lacks 3-arg "split". It has it.
9550 Mention that FS must be a single character, and a few other
9551 99-byte limits of traditional Awk.
9552 Mention that if (i in a) doesn't work with traditional Awk.

9558 (Newline-CODE-BS-newline in command):
9559 (Single-quote-BS-newline in command):
9560 (Single-quote-newline-BS-newline in command):
9561 Use printf '%s\n' instead of echo, for portability to hosts
9562 where echo interprets backslashes. This will break on hosts
9563 that lack printf, but for now let's assume all such hosts
9564 are dead (if not, we should get reports of test failures).
9566 2006-11-17 Paul Eggert <eggert@cs.ucla.edu>
9568 'echo' has some portability problems, when given a first argument
9569 with a leading '-', or when given any argument containing '\'.
9570 Avoid using 'echo' in these cases.
9571 * bin/Makefile.am $(bin_SCRIPTS): Rewrite to avoid 'echo' entirely.

9599 * lib/autoconf/general.m4 (AC_MSG_RESULT, AC_MSG_RESULT_UNQUOTED):
9600 Don't use ECHO_T, since ECHO_N is now reliable.
9601 * lib/autotest/general.m4 (AT_INIT): Likewise.
9602 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Use sed "$script"
9603 rather than using a here-document to put the script into a file.
9604 (_AC_DO_ECHO): Hoist the eval out of the echo, so that we can
9606 * lib/m4sugar/m4sh.m4 (AS_VAR_GET): Likewise.
9607 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Use
9608 AS_ECHO_N rather than ECHO_N and ECHO_C. This doesn't fix any
9609 bug, but we might as well stop using ECHO_N and ECHO_C internally.
9610 * lib/autotest/general.m4 (AT_SETUP): Likewise.

9612 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
9613 (_AC_OUTPUT_MAIN_LOOP): Rework echo so that it has just one
9614 operand, as AS_ECHO requires. Avoid double file name expansion.
9615 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Invoke _AS_ECHO_PREPARE.
9616 Don't set as_nl, since _AS_ECHO_PREPARE does that now.
9617 (_AS_PREPARE): Comment that _AS_ECHO_N_PREPARE is just for user code.
9618 (AS_ECHO, AS_ECHO_N, _AS_ECHO_PREPARE): New macros.
9619 * tests/c.at (AC_PROG_CPP without warnings, AC_PROG_CPP via CC):
9620 Double-quote strings that would otherwise contain M4 comments.
9621 * tests/m4sh.at (AS_ECHO and AS_ECHO_N): New test.
9623 * configure.ac (AC_INIT): Bump to 2.61a.
9626 2006-11-17 Paul Eggert <eggert@cs.ucla.edu>
9630 * configure.ac (AC_INIT): Bump to 2.61.
9633 * tests/autotest.at (Macro with backslash in a test title):
9634 Comment out for now, as this tests neither fails nor passes
9635 reliably. Problem reported by Ralf Wildenhues.
9637 2006-11-16 Paul Eggert <eggert@cs.ucla.edu>
9639 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE): Fix some typos
9640 in previous change, which caused test failures.

9750 and Stepan Kasal <kasal@ucw.cz>
9752 Handle special characters in test case titles correctly.
9753 * lib/autotest/general.m4 (AT_INIT): M4-quote and AS_ESCAPE AT_help_all
9755 (AT_SETUP): M4-quote and AS_ESCAPE the title properly everywhere.
9756 * tests/autotest.at (AT_CHECK_AT_TITLE): Add EXPANDED-TITLE-TO-TEST
9757 argument. Extend to check titles printed by ./micro-suite and
9758 ./micro-suite -l and the title in micro-suite.log.
9759 (Backquote in a test title,
9760 Single-quote in a test title,
9761 Double-quote in a test title): Don't expect failure anymore.
9762 (Backslash in a test title): Put a non-whitespace character after the
9763 backslash so that Bourne shells might actually see it as an escape
9765 (Brackets in a test title,
9766 Pound in a test title,
9767 Comma in a test title,

9783 2006-10-26 Paul Eggert <eggert@cs.ucla.edu>
9785 * tests/base.at (AC_COMPUTE_INT): Test **0** rather than 1 / 0,
9786 since powerpc-apple-darwin8-gcc-4.0.1 (Apple Computer, Inc. build
9787 5363) simply issues a warning when dividing by zero at compile
9788 time. Problem reported by Elias Pipping.
9790 2006-10-26 Eric Blake <ebb9@byu.net>
9793 * doc/autoconf.texi (Evaluation Macros): Improve the example to
9794 show effect on macros that expand with commas.

9822 If FUNCTION-BODY is nonempty, use AC_LINK_IFELSE rather than
9823 AC_COMPILE_IFELSE, to work around problem with OSF/1 4.0F fseeko
9824 reported by Nelson H. F. Beebe for Coreutils 6.4.
9826 * tests/tools.at (autoconf --trace: user macros): Remove test
9827 for tracing multiline macros, since m4 1.4.7a uses a different
9828 way to number lines. Problem reported by Ralf Wildenhues.

9906 (Imported from Automake.)
9907 * build-aux/install-sh (posix_mkdir): Reject FreeBSD 6.1 mkdir -p -m,
9908 which incorrectly sets the mode of an existing destination
9909 directory. In some cases the unpatched install-sh could do the
9910 equivalent of "chmod 777 /" or "chmod 0 /" on a buggy FreeBSD
9911 system. We hope this is rare in practice, but it's clearly worth
9912 fixing. Problem reported by Alex Unleashed in
9913 <http://lists.gnu.org/archive/html/bug-autoconf/2006-10/msg00012.html>.
9914 Also, don't bother to check for -m bugs unless we're using -m;
9915 suggested by Stepan Kasal.

9993 (_AS_TEST_PREPARE): Set as_test_x rather than as_executable_p.
9994 Use a better substitute, by inspecting the output of "ls"
9995 rather than just using ":".
9996 * lib/autoconf/general.m4 (_AC_LINK_IFELSE): Use AS_TEST_X
9997 rather than AS_EXECUTABLE_P, since we needn't worry about
9998 non-regular files here.
10000 * NEWS: Autoconf-generated shell scripts no longer export BIN_SH,
10001 due to configuration hassles with this. See Tonya Underwood's report

10025 * lib/autoconf/c.m4 (_AC_PROG_PREPROC_WORKS_IFELSE): Remove
10026 comment about ac_cpp_err; it was incorrect, and anyway
10027 ac_cpp_err is being removed below.
10028 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE): Don't
10029 set ac_cpp_err to 'yesyes' if preproc_warn_flag and werror_flag
10030 are both 'yes'. In fact, don't bother setting ac_cpp_err at all;
10032 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't log our funky tests
10033 with werror_flag and conftest.err and so forth. This is more
10034 compatible with how _AC_PROG_PREPROC_WORKS_IFELSE behaves,
10035 and anyway the user shouldn't normally want to see this gorp logged.
10036 Problem reported by Ralf Wildenhues.
10037 * lib/autoconf/lang.m4 (AC_LANG_WERROR): werror_flag's default is
10038 empty, not 'no', since the rest of the code uses 'test -z'.
10040 2006-10-04 Paul Eggert <eggert@cs.ucla.edu>
10042 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE):
10043 Use a single call to AC_DO_TOKENS rather than multiple, for

10046 Problem reported by mwoehlke in

10049 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Use "test -x /" rather
10050 than creating a file to use with test -x; this is much faster.
10052 2006-10-02 Bruno Haible <bruno@clisp.org>
10054 * lib/autom4te.in (Automake-preselections): Add

10064 * lib/autoconf/functions.m4 (AC_FUNC_FSEEKO): Don't compile the
10065 fseeko testing program twice; just use the earlier result.
10066 * lib/autoconf/specific.m4 (_AC_SYS_LARGEFILE_MACRO_VALUE):
10067 Set cache var to 'unknown' (not 'no') if leaving the macro unset
10068 still doesn't let the program compile.
10069 (AC_SYS_LARGEFILE): Test for _LARGE_FILES only if earlier tests
10072 * lib/autoconf/functions.m4: Fix problems reported by Ralf Wildenhues.
10073 (AC_FUNC_ERROR_AT_LINE): Don't bother to check for error.h. Just
10074 include it, without including anything else.
10075 (AC_FUNC_FSEEKO): Avoid gcc -Wall warnings about constant
10077 (AC_FUNC_STRNLEN): Require AC_USE_SYSTEM_EXTENSIONS.

10480 --help' should mention that `--version' outputs configuration
10481 settings. Report by Bruno Haible.

10513 CPPFLAGS, and LDFLAGS better. Problem reported by Bruno Haible.

10536 2006-07-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10538 * doc/autoconf.texi: Fix some typos.
10540 2006-07-07 Paul Eggert <eggert@cs.ucla.edu>
10542 * tests/torture.at (Configuring subdirectories): Set CONFIG_SITE
10543 more globally, since the 2006-06-30 patch didn't suffice. Problem
10544 reported by Keith Marshall. Also, don't bother with builddir2,
10545 since it shouldn't be needed any more.
10547 2006-07-07 Paolo Bonzini <bonzini@gnu.org>
10549 * doc/autoconf.texi (Generic compiler characteristics):

10566 2006-07-02 Paul Eggert <eggert@cs.ucla.edu>
10568 * lib/autoconf/types.m4 (AC_TYPE_LONG_LONG_INT):
10569 Require that long long int be at least 64 bits wide. C99 requires
10570 this and enough programs depend on it so we should check for it.
10571 Bruno Haible reports in
10572 <http://lists.gnu.org/archive/html/bug-gnulib/2006-06/msg00286.html>
10573 that long long int is 32 bits wide with some nonstandard compilers.

10578 * tests/torture.at (Configuring subdirectories): Set CONFIG_SITE
10579 to a nonexistent file, so that we don't have to worry about
10580 a local site configuration that doesn't use /usr/local.
10581 Problem reported by Keith Marshall in
10582 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00133.html>.
10584 2006-06-28 Paul Eggert <eggert@cs.ucla.edu>
10586 * doc/autoconf.texi: Be more consistent about using @acronym with
10587 "HP" and "HP-UX". Remove mention of OSF; the old version wasn't
10588 quite right (it talked about "OSF/Tru64", even though the
10589 operating systems were called OSF/1, Digital UNIX, and Tru64 UNIX,
10590 and it even mentioned "OSF 4"!) and at this point there's little
10591 reason to talk about OSF any more, since it died in 1994.
10592 (Specific Compiler Characteristics): Simplify example of
10593 negative-size array.
10594 (File Descriptors): Reorder to make the text flow better.
10595 Remove joke about "appreciate the various levels"; I didn't get it.
10596 Add remark about HP-UX sh -x bug with stderr noted by Bob Proulx in
10597 <http://lists.gnu.org/archive/html/bug-coreutils/2006-06/msg00225.html>.
10598 (File Descriptors, Limitations of Usual Tools):
10599 Tone down the advice against renaming or removing open files.
10600 (Limitations of Usual Tools): Add a new section, on 'rm'.
10602 2006-06-26 Stepan Kasal <kasal@ucw.cz>
10604 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Use -lX11, not
10605 -lXt in LIBS, idea from Karsten Hopp; this was due since
10608 2005-09-18 Paul Eggert <eggert@cs.ucla.edu>
10609 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Look for X11/Xlib.h
10610 and XrmInitialize rather than X11/Intrinsic.h and XtMalloc
10611 (which belong to Xt, not X itself). See Debian bug 327655.
10613 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10615 * configure.ac (AC_INIT): Bump to 2.60a.

10635 datarootdir-related errors only if AC_DATAROOTDIR_CHECKED is
10637 * doc/autoconf.texi (Changed Directory Variables): New node,
10638 to document the whole `datarootdir' business a bit better.
10640 * tests/torture.at (datarootdir workaround): Extend test.
10641 Prompted by report by Alexandre Julliard.
10643 2006-06-22 Paul Eggert <eggert@cs.ucla.edu>
10645 * lib/autoconf/c.m4 (_AC_PROG_CC_C89): Check for C89 incompatibility

10655 2006-06-20 Paul Eggert <eggert@cs.ucla.edu>
10657 * NEWS: Use "M4" rather than "m4" when appropriate.
10658 Problem reported by Eric Blake.
10659 * doc/autoconf.texi: Likewise.
10660 Use @acronym around BSD, GCC, and GNU when appropriate.
10661 (Why GNU M4): Renamed from "Why GNU m4".
10662 (Redefined M4 Macros): Mention that Posix
10663 m4wrap takes only 1 argument, but GNU M4 1.4.x takes more.
10664 (Buffer Overruns): Mention size_t and ptrdiff_t as alternatives
10667 2006-06-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10669 * bin/autom4te.in (handle_output): Do not forbid the empty
10671 * tests/tools.at (autoconf: the empty token): New test.
10673 2006-06-20 Stepan Kasal <kasal@ucw.cz>
10675 * lib/m4sugar/m4sugar.m4 (m4_init): Merge the two m4_wrap
10676 calls, so that we do not care whether they are LIFO or FIFO;
10677 in the m4_wrap, do not check which diversion is the topmost
10678 one, just check that the stack is balanced at the end.
10679 * lib/m4sugar/m4sh.m4 (AS_INIT): We are going to change the
10680 base diversion forever--pop the previous diversion before
10681 opening the new one; consequently, remove the m4_wrap call.
10682 * lib/autotest/general.m4 (AT_INIT): Likewise.
10683 * tests/m4sugar.at: Do not use
10684 m4_wrap([m4_diversion_pop([..])]), for educational purposes.
10686 2006-06-19 Paul Eggert <eggert@cs.ucla.edu>
10687 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10689 * NEWS: Document that m4wrap/m4_wrap might not be LIFO.
10690 * doc/autoconf.texi (Redefined M4 Macros): Likewise.
10691 Rework example of m4wrap token-pasting trouble so that it doesn't
10692 care whether it's LIFO or FIFO.
10693 Fix some "contrary to"s that are awkward in English.
10695 2006-06-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10697 * lib/autoconf/types.m4 (_AC_TYPE_INT): Set `$ac_cv_c_int$1_t'
10698 to `yes' instead of `int$1_t' if the type is found, for more
10699 consistent configure output (where $1 is the number of bits).
10700 (_AC_TYPE_UINT): Likewise for `uint$1_t'.
10701 Suggested by Bruno Haible.
10703 * lib/autoconf/types.m4 (_AC_TYPE_UNSIGNED_INT): Solaris 2.5.1
10704 needs _UINT8_T and _UINT64_T defines as well, to avoid clashes
10705 with system headers. Report by Bruno Haible.
10707 2006-06-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10709 * config/config.guess, config/config.sub: Sync from upstream.
10711 * bin/Makefile.am (autoconf.in): Use `--melt' for autom4te,
10712 in order to avoid picking up an older installed frozen m4sh.m4f.
10713 Besides an outdated shell startup, this could have been created
10714 by an earlier M4 version with incompatible frozen file format.
10716 2006-06-16 Paul Eggert <eggert@cs.ucla.edu>
10718 * README: Recommend m4 1.4.4 instead of 1.4.3..
10719 * doc/autoconf.texi: Likewise.
10720 (Special Chars in Names): Say that $(.FOO) is portable, as
10721 suggested by Stepan Kasal.
10722 (Installation Directory Variables, Build Directories):
10723 (Automatic Remaking, Subdirectories, Fortran Compiler):
10724 (Making testsuite Scripts, Defining Directories):
10725 Quote variable usages better.
10726 (Making testsuite Scripts): Add clean-local rule to makefile
10727 snippet, by Eric Blake.
10728 (Installation Directory Variables): Fix table item font.
10729 Reword slightly to clarify. Generalize advice about
10730 not using special characters to include all file-related
10731 vars, not just VPATH.
10732 (Special Chars in Variables): Warn about special characters in
10734 (Assignments): Clarify default-value example as suggested by
10736 <http://lists.gnu.org/archive/html/autoconf-patches/2006-06/msg00072.html>.
10737 (Special Shell Variables): Note leading ./ or ../, as suggested
10739 (Limitations of Builtins): Under cd, warn about CDPATH.

10746 `@var', for texi2html.
10747 (Systemology): Some more word wrapping, for DVI output.
10748 (autom4te Invocation): The short option for `--melt' is `-M',
10751 2006-06-15 Paul Eggert <eggert@cs.ucla.edu>
10753 * doc/autoconf.texi: More formatting and English tweaks,
10754 many suggested by Ralf Wildenhues.
10755 Reword to avoid "@code{...}'s" and the like, since it's ugly
10756 with Emacs info mode. discontents -> woes.
10757 Put a few "will"s back. time stamp -> timestamp.
10758 side-effect -> side effect.
10760 2006-06-14 Paul Eggert <eggert@cs.ucla.edu>
10762 * doc/autoconf.texi (Initializing configure, Shell Substitutions):
10763 Warn about $@ not persisting. Problem reported by Julien Danjou in
10764 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=372179>.
10765 (Special Chars in Names): Renamed from Leading _ in Macro Names.
10766 Mention other special chars, too.
10768 2006-06-14 Eric Blake <ebb9@byu.net>
10770 * doc/autoconf.texi (The Make Macro MAKEFLAGS): New node.
10772 2006-06-13 Paul Eggert <eggert@cs.ucla.edu>
10774 * doc/autoconf.texi: Some systematic minor improvements, as
10775 follows. Use "makefile" when talking about makefiles
10776 generally (which might be named "makefile" or "Makefile" or even
10777 "foo.mk"), "Makefile" when talking about a specific makefile
10778 called "Makefile". This unclutters the text from weird quotes
10779 (e.g., "`Makefile's" in info mode). Similarly, use "@var{foo}
10780 values" rather than "@var{foo}s" and similar constructs containing
10781 "}s". Use "Make rules" rather than "Makefile rules". Minor
10782 English-language improvements. Change the prefix "sub-" to "sub"
10784 Put blank lines around examples more consistently.
10785 Avoid "rather" and "very" as intensifiers.
10786 Avoid "will" as an auxiliary.
10787 (Limitations of Make): Split this node into....
10788 (Portable Make, $< in Ordinary Make Rules, Failure in Make Rules):
10789 (Leading _ in Macro Names, Backslash-Newline-Newline):
10790 (Backslash-Newline Comments, Long Lines in Makefiles):
10791 (Macros and Submakes, The Make Macro SHELL, Comments in Make Rules):
10792 (obj/ and Make, make -k Status, VPATH and Make):
10793 (VPATH and Double-colon, $< in Explicit Rules):
10794 (Automatic Rule Rewriting, OSF/Tru64 Directory Magic):
10795 (Make Target Lookup, Single Suffix Rules, Timestamps and Make):
10796 New nodes, resulting from splitup of Limitations of Make.
10797 All cross-references changed. Raise the top node from
10798 a section to a chapter, and all subnodes accordingly.
10799 Redo the introductory wording to match the new organization.
10800 (Installation Directory Variables): Use an example that is
10801 closer to what Autoconf actually does. Mention that VPATH's
10802 value should not contain metacharacters or white space.
10803 (Fortran Compiler): Fix a VPATH bug in an example.
10804 (Leading _ in Macro Names): Mention that this problem is no longer
10805 of practical concern.
10806 (VPATH and Make): Reword the advice to make it clearer
10807 that Autoconf and Automake support VPATH in non-GNU make, but
10808 many packages have bugs in this area.
10809 ($< in Explicit Rules): Refer to Build Directories rather
10810 than using a (non-VPATH-safe) example.
10811 (Automatic Rule Rewriting): Mention the sort of disaster that
10812 can ensue with Solaris-style rule rewriting with VPATH.
10814 2006-06-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10816 * doc/install.texi (Compilers and Options): Weaken the
10817 suggestion to use GNU make for VPATH builds.
10819 * lib/autom4te.in (Automake-preselections): Add AM_PROG_CXX_C_O,
10820 AM_PROG_F77_C_O, AM_PROG_FC_C_O, AC_FC_SRCEXT, AC_FC_FREEFORM.

10823 in regular expression.
10825 2006-06-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10827 * doc/autoconf.texi (Installation Directory Variables):
10828 Drop extra @samp from `@table @samp' item.
10829 (Limitations of Usual Tools): Comment fix.
10830 Do not nest @samp just to point to other table items.
10831 (Writing testsuite.at) <AT_CHECK>: The second argument to
10832 `@dvar' is already @samp'ed.
10833 (Making testsuite Scripts) <AC_CONFIG_TESTDIR>: Likewise,
10834 do not use @var in the second argument.

10839 $as_shell.exe too. Problem reported by Andreas Buening in
10840 <http://lists.gnu.org/archive/html/autoconf/2006-06/msg00038.html>.
10842 2006-06-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10844 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA): Work around
10845 `unused variable' compiler warning, for `-Wall -Werror'.
10846 Reported by Jaap Haitsma in
10847 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00012.html>.
10849 2006-06-06 Paul Eggert <eggert@cs.ucla.edu>
10851 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Remove core file, in
10852 case the compiler dumps core. Problem reported for
10853 OpenServer 5.0.7 by Tim Rice in
10854 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00019.html>.

10870 * NEWS: Don't blame non-GNU VPATH compatibility issues on Automake.
10872 * doc/autoconf.texi (Integer Overflow): Mention that INT_MIN % -1
10873 typically overflows on x86 CPUs, even though the C standard
10874 requires otherwise.
10876 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10878 * configure.ac (AC_INIT): Bump to 2.59e.
10881 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10885 * config/texinfo.tex: Sync from upstream.
10887 * bin/autoreconf.in: Trace `LT_CONFIG_LTDL_DIR'; if it has been
10888 seen, invoke libtoolize with `--ltdl' argument.
10889 * lib/autom4te.in (Autoreconf-preselections): Adjust.
10891 Suggested by Eric Blake.
10893 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
10895 * NEWS: Whoops! AC_FUNC_STRNLEN isn't obsolescent. Problem
10896 reported by Ralf Wildenhues.

10910 message issued by AC_REQUIRE.
10911 * tests/m4sugar.at: Check m4_require's error message.
10912 * tests/base.at: Check AC_REQUIRE's error message.
10913 * tests/local.at (AT_CHECK_M4): New macro, almost identical
10915 (AT_CHECK_AUTOM4TE): ... which is now a thin wrapper around
10917 (AT_CHECK_AUTOCONF): Use AT_CHECK_M4; no longer support
10918 `expout' as the last parameter.
10919 * tests/tools.at: Adapt to the above change.
10921 2006-06-04 Stepan Kasal <kasal@ucw.cz>
10923 * doc/autoconf.texi (Limitations of Usual Tools): Correct
10924 information about race-free implementations of mkdir.
10926 2006-06-04 Eric Blake <ebb9@byu.net>
10928 * bin/autoreconf.in (help): Document M4 environment variable.
10929 * bin/autoconf.as (Usage): Likewise.

10933 2006-06-04 Paul Eggert <eggert@cs.ucla.edu>
10935 * NEWS: GNU make now recommended for VPATH builds.
10936 Mention that some macros are now documented to be obsolescent.
10937 * doc/autoconf.texi:
10938 Prefer "current" to "modern" to describe
10939 currently-used (albeit perhaps old-fashioned) hosts.
10940 Mention which ancient features no longer need to be worried about.
10941 setgid -> set-group-ID
10942 setuid -> set-user-ID (these are the Posix terms)
10943 Fix some misuses of "only".
10944 (AC_C_BACKSLASH_A, AC_C_CONST, AC_C_PROTOTYPES):
10945 (AC_C_STRINGIZE, AC_C_VOLATILE, AC_FUNC_CLOSEDIR_VOID):
10946 (AC_FUNC_GETPGRP, AC_FUNC_LSTAT, AC_FUNC_MEMCMP):
10947 (AC_FUNC_SELECT_ARGTYPES, AC_FUNC_SETPGRP):

10951 (AC_HEADER_SYS_WAIT, AC_HEADER_TIME, AC_ISC_POSIX):
10952 (AC_PROG_GCC_TRADITIONAL, AC_STRUCT_TM):
10953 Mention that these macros are obsolescent.
10954 (Installation Directory Variables): shall -> should
10955 (File Descriptors): Mention that 0, 1, 2 might get reopened.
10956 Mention that it's now safe to use 3 and 4.
10957 (Limitations of Usual Tools): cp -r is now specified by Posix.
10958 Omit longwinded and obsolescent discussion of cp -f.
10959 Modernize discussion of expr, ls.
10960 (Limitations of Make): Modernize discussion of VPATH builds.
10961 Mention $? as a workaround in some cases.
10962 * doc/install.texi (Basic Installation):
10963 Mention "./configure; make; make install" first. Be more
10964 specific about why this file is generic. Remove unnecessary
10965 parens. Remove misleading "only". Remove obsolete advice
10966 about csh. Don't say "configure" takes awhile; say it
10967 might take a while. Suggest CFLAGS=-g rather than CFLAGS=-O2,
10968 and CC=c99 rather than CC=c89, as these are blessed by current
10969 Posix. Recommend GNU make if doing a VPATH build.
10971 2006-06-03 Paul Eggert <eggert@cs.ucla.edu>
10973 * doc/autoconf.texi: Use a consistent style "$ @kbd{...}" for
10974 examples involving shell prompts.
10976 2006-06-02 Stepan Kasal <kasal@ucw.cz>
10977 and Paul Eggert <eggert@cs.ucla.edu>
10979 * doc/autoconf.texi (Here-Documents): Add details about the
10980 pre-ksh93g bug. Reword slightly to make it clearer. Consistently
10981 use "here-documents" instead of "here documents".
10983 2006-06-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10985 * config/texinfo.tex, doc/standards.texi: Sync from upstream.

10990 anywhere in directory names.
10992 2006-05-31 Paul Eggert <eggert@cs.ucla.edu>
10994 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be even more conservative
10995 about quoting the case statement, just in case.
10996 * doc/autoconf.texi (Here-Documents): Mention that the ksh bug
10997 was fixed in ksh93g; reported by Ralf Wildenhues.
10999 2006-05-31 Stepan Kasal <kasal@ucw.cz>
11001 * doc/autoconf.texi (System Services): Do not document
11002 overriding EXEEXT via ac_cv_exeext=ext.
11003 (Particular Programs) <AC_PROG_MKDIR_P>:
11004 Document that ${MKDIR_P} understands --.

11008 2006-05-31 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11010 * lib/m4sugar/m4sh.m4 (_AS_DIRNAME_PREPARE): Guard against test
11011 argument with leading hyphen. Problem reported by Paul Eggert.
11013 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
11015 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be more conservative
11016 about quoting ac_try: quote all of it, if any of it seems suspicious.
11017 This means we don't have to worry about ${ or sed any more.
11018 Also, double-quote the case statement, to work around misuses via
11019 underquoting as reported by Ralf Wildenhues in
11020 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00169.html>.
11021 (_AC_EVAL_STDERR): Revert, since evidently some packages rely on this
11022 undocumented and dangerous macro.
11023 Problem reported by Ralf Wildenhues in
11024 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00168.html>.

11032 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
11034 * lib/autoconf/general.m4: Revert AC_TRY_EVAL and AC_TRY_COMMAND,
11035 since evidently some packages rely on the old, broken behavior.
11036 Problem reported by Ralf Wildenhues in
11037 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00160.html>.
11038 (AC_TRY_EVAL, AC_TRY_COMMAND, _AC_EVAL): Go back to the
11039 pre-2006-05-26 definitions, but leave in the comments that
11040 these macros are dangerous and should not be used.
11041 (_AC_DO_ECHO): Renamed from _AC_EVAL_ECHO. All callers changed.
11042 (_AC_DO): Renamed from _AC_EVAL. All callers changed.
11043 (_AC_DO_STDERR): Renamed from _AC_EVAL_STDERR. All callers changed.
11044 (_AC_DO_VAR): Renamed from AC_TRY_EVAL.
11045 (_AC_DO_TOKENS): Renamed from AC_TRY_COMMAND.
11047 2006-05-29 Paul Eggert <eggert@cs.ucla.edu>
11049 * lib/autoconf/status.m4 (AC_OUTPUT_MAKE_DEFS): Rewrite to avoid
11050 the use of 'tr', since this is our only use of 'tr'.

11053 and Paul Eggert <eggert@cs.ucla.edu>
11055 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE):
11056 Don't assume 'grep' works on long lines, since AIX grep doesn't.
11058 2005-05-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11060 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Do not use `grep' on
11061 the output file in the `${datarootdir}' test.
11063 2005-05-28 Stepan Kasal <kasal@ucw.cz>
11064 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11066 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If we have not seen
11067 mention of `datarootdir' in the input file(s), but literal
11068 `${datarootdir}' in the output file, and we haven't warned yet,
11069 then warn as well: the user may have (erroneously) used
11070 `AC_SUBST([mydatadir], [$datadir/my])' instead of the correct
11071 `AC_SUBST([mydatadir], ['${datadir}/my'])'.
11072 * tests/torture.at (datarootdir workaround): Extend this test.
11075 2006-05-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11076 and Paul Eggert <eggert@cs.ucla.edu>
11078 * doc/autoconf.texi (autoheader Invocation): The first argument to
11079 `AC_DEFINE_UNQUOTED' need not be a literal. Mention the
11080 alternatives and clear up the language a bit.
11082 2006-05-27 Paul Eggert <eggert@cs.ucla.edu>
11084 * NEWS: Reword notice for AC_TRY_COMMAND, AC_TRY_EVAL,
11085 ac_config_guess, ac_config_sub, ac_configure.
11086 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
11087 Fix typo that prevented an unnecessary space from being removed.
11088 Problems reported by Ralf Wildenhues in:
11089 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00143.html
11091 2006-05-26 Paul Eggert <eggert@cs.ucla.edu>
11093 * doc/autoconf.texi (Particular Programs, Limitations of Usual Tools):
11094 Use better wording to talk about AC_PROG_MKDIR_P's thread-safety.
11095 Don't use the term "thread-safe" to talk about mkdir race
11096 conditions, since the problem is more a process than a thread
11097 issue. Problem reported by Stepan Kasal in:
11098 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00088.html
11099 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Use code that mimics
11100 the test for 'install' more closely. Look at MKDIR_P first.
11101 Look in the PATH, and at /opt/sfw/bin.
11102 Look for a 'gmkdir' program as well (Solaris 10 /opt/sfw/bin/gmkdir).
11103 Don't bother to try mkdir -p, since we already check mkdir --version;
11104 just look at the version number. (There's no easy way to check
11105 for race-free implementations.)
11106 * tests/tools.at (autoconf: subdirectories): Adjust to above
11107 changes, since MKDIR_P now might end in "/mkdir -p".
11109 * doc/autoconf.texi (autoheader Invocation): Mention that the
11110 first arg of AC_DEFINE_UNQUOTED must be a literal.
11111 Problem reported by Ben Pfaff in
11112 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00090.html>.
11114 * NEWS: Mention that AC_TRY_COMMAND and AC_TRY_EVAL may be removed.
11115 * doc/autoconf.texi (Special Chars in Variables): New section.
11116 (Preset Output Variables): Warn about special chars in CPPFLAGS.
11117 (Installation Directory Variables): Quote $(datadir) better.
11118 (Limitations of Builtins): Describe some of eval's trickiness.
11120 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Simplify quoting.
11121 * lib/autoconf/fortram.m4 (_AC_PROG_FC_V_OUTPUT): Likewise.
11122 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Put leading space
11123 in front of every arg, not just trailing args. Quote apostrophes.
11124 (_AC_EVAL_ECHO): New macro.
11125 (_AC_EVAL, AC_EVAL_STDERR): Use it. Quote arg of eval.
11126 (AC_TRY_EVAL, AC_TRY_COMMAND): Mention that these macros might get
11128 (_AC_LINK_IFELSE): Use proper rule for shell continuation lines,
11129 exposed by quoting of eval argument. Put the command on line line
11131 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): Use eval more safely.
11132 (_AC_PATH_X, AC_PATH_X): Quote more safely.
11133 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Use eval more safely.
11134 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Don't use eval.
11135 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Minor style change.
11136 Handle special chars in prefix, ac_srcdir, ac_aux_dir.
11137 Use eval more safely.
11138 (_AC_OUTPUT_CONFIG_STATUS): Adjust to above changes.
11139 * lib/m4sugar/m4sh.m4 (AS_VAR_GET): Note that this API needs
11141 * tests/base.at (AC_TRY_COMMAND): Use proper rule for shell continuation
11142 lines, exposed by quoting of eval argument.
11144 2006-05-26 Stepan Kasal <kasal@ucw.cz>
11145 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11147 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Drop the
11148 initialization of `ac_cv_exeext', do not override it if it was
11149 already set, unless it was set to `no', for compatibility with
11150 Autoconf-2.13, and comment this.
11151 Do not export `ac_cv_exeext', Libtool hasn't needed this for years.
11152 (_AC_COMPILER_EXEEXT_DEFAULT): Likewise, do not export it.
11153 (_AC_COMPILER_EXEEXT_WORKS, _AC_COMPILER_EXEEXT_CROSS): Typos.
11154 * doc/autoconf.texi (Compilers and Preprocessors) <EXEEXT>:

11164 check, s/ac_exeext/ac_cv_exeext/. Fixes regression introduced
11167 2006-04-01 Stepan Kasal <kasal@ucw.cz>
11168 Clean up _AC_COMPILER_EXEEXT* macros.
11169 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't try to
11170 detect exeext, it will be done by _AC_COMPILER_EXEEXT_O; just set
11171 ac_file to the name of the default output file and call
11172 _AC_COMPILER_EXEEXT_WORKS. Move the definition of ac_files and the
11173 initial `rm' of the candidate files...
11174 (_AC_COMPILER_EXEEXT): ... here and simplify them. Moreover, use
11175 the same list in subsequent `rm' calls, and for the temporary
11176 redefinition of ac_clean_files; call _AC_COMPILER_OBJEXT at the end,
11177 and don't call the other _AC_COMPILER_EXEEXT_* macros directly, use...
11178 (_AC_COMPILER_EXEEXT_TESTS): ... this new macro.
11179 (_AC_COMPILER_EXEEXT_O): Don't export ac_cv_exeext, it's not needed (or
11180 no longer needed) by libtool. Make it a cache check.
11181 (_AC_COMPILER_EXEEXT_CROSS): Remove the comment, it was obviously
11182 copied here by mistake.
11183 (AC_NO_EXECUTABLES): Redefine _AC_COMPILER_EXEEXT_TESTS, not
11184 _AC_COMPILER_EXEEXT.
11185 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX, AC_PROG_OBJC): Do not call
11186 _AC_COMPILER_OBJEXT directly.

11198 * lib/Autom4te/XFile.pm (lock): Allow EOPNOTSUPP, besides
11199 ENOLCK. Only mention `make -j' when applicable. Only raise
11200 fatal errors when `make -j' is involved. Improve error message.
11202 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11204 * doc/autoconf.texi (Here-Documents): We now know more about
11205 the variable expansion in here documents bug.
11206 Thanks to Tim Rice and Stepan Kasal.
11208 * doc/autoconf.texi (Making testsuite Scripts): Add an example
11209 how to use TESTSUITEFLAGS. Suggested by Eric Blake.
11211 2006-05-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11213 * tests/autotest.at (Multiline command from M4 expansion):
11214 No failure to be expected if the shell quotes newlines in
11215 commands in the `set -x' output. Report by Tim Rice.
11218 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
11220 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Don't use shell
11221 expansion in the here-documents used by config.status, as that
11222 runs afoul of the Korn shell version M-12/28/93d bug described in
11223 the Autoconf manual, and this in turn causes a Coreutils 5.95 build to
11224 fail as described by Tim Rice and diagnosed by Ralf Wildenhues in
11225 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00082.html>.
11227 2006-05-23 Jim Meyering <jim@meyering.net>
11229 * lib/autoconf/functions.m4 (AC_FUNC_LSTAT_FOLLOWS_SLASHED_SYMLINK):
11230 Fix typo introduced with 2006-04-02 change. It reversed the sense
11233 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
11235 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Simplify ac_dA and
11236 ac_dB slightly, to save bytes in the script.
11237 Max out at 50 lines, rather than 96; this is more likely
11238 (though not guaranteed) to avoid obscure 'sed' failures.
11240 2006-05-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11242 * lib/autotest/general.m4 (AT_INIT): UnixWare `tr' may interpret
11243 `tr -d -' as bad option argument. Work around this by deleting
11244 an unrelated character.
11245 Report by Tim Rice <tim@multitalents.net>.
11247 2006-05-22 Paul Eggert <eggert@cs.ucla.edu>,
11248 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
11249 Stepan Kasal <kasal@ucw.cz>
11251 * doc/autoconf.texi (Particular Programs): Do not promise that
11252 we always prefer the GNU version of the program, and that we
11253 search according to PATH; both rules can have exceptions.
11254 Update description of AC_PROG_GREP, AC_PROG_EGREP, AC_PROG_FGREP,
11255 AC_PROG_SED. Move descriptions of limitations
11256 to the Limitations of Usual Tools section.
11257 (Limitations of Usual Tools) <sed>: Mention script length
11258 limitations with Solaris /usr/ucb/sed.
11259 <grep>: Fix wording for empty alternative. Mention that -c and
11260 -l should not be combined, and that -E and -F should not be
11263 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
11264 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11266 * lib/autoconf/programs.m4 (AC_PROG_SED): Catch script length
11267 limits in Solaris 8 /usr/ucb/sed by testing a long script.
11269 2006-05-22 Stepan Kasal <kasal@ucw.cz>
11271 * doc/autoconf.texi (Defining Symbols): Literal parameter of
11272 AC_DEFINE is now passed to m4_pattern_allow.
11273 * NEWS: Mention that; likewise for AC_SUBST.
11274 * lib/autoconf/general.m4 (AC_DEFINE_TRACE_LITERAL): Pass
11275 the parameter to m4_pattern_allow.
11276 * tests/tools.at: Add a check for that.
11278 2006-05-22 Stepan Kasal <kasal@ucw.cz>
11280 * lib/autoconf/status.m4: Fix typos.
11282 2006-05-21 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11284 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Remove
11285 only the files that this macro generates.
11287 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
11289 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: For
11290 the HP-UX sed limitation of 99 commands, labels do not count.
11291 * lib/autoconf/status.m4 (_AC_SED_CMD_LIMIT): Mention that
11293 (_AC_OUTPUT_HEADER): Revert the change from 2006-05-19.
11295 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
11297 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT):
11298 Import the following fix from coreutils:
11300 2006-01-13 Jim Meyering <jim@meyering.net>
11302 Invoke AC_CHECK_FUNCS(getmntent) unconditionally so that tests of
11303 $ac_cv_func_getmntent (e.g., in gl_LIST_MOUNTED_FILE_SYSTEMS) need
11304 not double-quote uses of that variable, to accommodate the rare
11305 case in which getmntent is available in none of the libraries
11306 checked. This happens at least on FreeBSD 5.0.
11308 2006-05-20 Paul Eggert <eggert@cs.ucla.edu>
11310 * lib/autoconf/general.m4 (AC_CONFIG_AUX_DIRS): Bring back
11311 ac_config_guess, ac_config_sub, and ac_configure, since evidently
11312 some other programs unwisely rely on these undocumented vars.
11313 But put in warning comments about them.
11314 Problem reported by Ralf Wildenhues in
11315 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00068.html>.
11316 * NEWS: Document that these variables are intended to go away.
11318 2006-05-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11320 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): Require AC_PROG_CXX,
11321 and set the language to C++ (analogous to the equivalent Fortran
11324 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): New macro.
11325 * doc/autoconf.texi (C++ Compiler): Document it.
11326 * lib/autoconf/fortran.m4 (_AC_PROG_FC_C_O): Adjust comment.
11329 2006-05-19 Paul Eggert <eggert@cs.ucla.edu>
11331 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Fix off-by-one bug
11332 that caused config.status to generate 100-command sed scripts; the
11333 portable limit is 99.
11335 2006-05-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11337 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Name temporary
11338 variable `ac_d' instead of `d' to avoid infringing namespace.
11339 Report by Ralf Menzel.
11341 2006-05-18 Paul Eggert <eggert@cs.ucla.edu>
11343 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Don't prepend
11344 $ac_top_build_prefix to $MKDIR_P if it's just 'mkdir -p'.
11345 * tests/tools.at (autoconf: subdirectories): New test, taken from
11346 the corresponding problem report by Ralf Wildenhues in:
11347 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00053.html
11349 * lib/autoconf/functions.m4 (AC_REPLACE_FNMATCH, AC_FUNC_FNMATCH_GNU):
11350 Quote some uses of shell variables if they might suffer unexpected
11351 globbing. This doesn't fix all instances of quoting problems that
11352 I found, just the easy ones that look safe.
11353 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR, _AC_INIT_HELP):
11354 (AC_CONFIG_AUX_DIR, AC_CONFIG_AUX_DIR_DEFAULT, AC_CONFIG_AUX_DIRS):
11355 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST, AC_CANONICAL_TARGET):
11356 (AC_CACHE_LOAD, AC_CACHE_SAVE): Likewise.
11357 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF, _AC_PATH_X_DIRECT): Likewise.
11358 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Likewise.
11359 * lib/autoconf/status.m4 (_AC_OUTPUT_LINK, _AC_OUTPUT_SUBDIRS):

11364 2006-05-18 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11366 * bin/autoreconf.in ($help): Reword according to the manual.
11367 Suggested by Olly Betts.
11369 2006-05-17 Olly Betts <olly@survex.com> (tiny change)
11370 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11372 * bin/autoreconf.in: Pass the directory argument to
11373 `require_configure_ac'. Fix comment.
11374 * tests/torture.at (Configuring subdirectories): Expose this.
11375 Reported by Olly Betts.
11377 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11379 * lib/Automake/Configure_ac.pm, lib/Automake/Channels.pm,
11380 lib/Automake/FileUtils.pm, lib/Automake/Struct.pm: Sync from
11381 Automake as follows:
11383 * lib/Autom4te/Configure_ac.pm (find_configure_ac): Use
11384 `$configure_in' instead of `configure.in', to preserve
11385 directory component.
11387 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11389 * config/config.guess, config/config.sub, config/texinfo.tex,
11390 doc/make-stds.texi, doc/standards.texi: Sync from upstream.
11392 2006-05-14 Paul Eggert <eggert@cs.ucla.edu>
11394 * lib/autoconf/headers.m4 (AC_HEADER_STDBOOL): Fix overly-picky
11395 test for C99 conformance; (bool) 0.5 is an integer constant
11396 expression, but (bool) -0.5 is not. Problem reported by Fedor
11397 Sergeev in <http://forum.sun.com/jive/thread.jspa?threadID=96202>.
11399 2006-05-13 Paul Eggert <eggert@cs.ucla.edu>
11401 * doc/autoconf.texi (Particular Programs): AC_PROG_MKDIR_P now
11402 sets MKDIR_P, not mkdir_p, to avoid collisions with Automake.
11403 Warn about obsolete install-sh files. Remove stray sentence
11404 fragment and fix cross reference.
11405 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Don't insist on
11406 install -d; this undoes the 2006-05-10 change.
11407 (MKDIR_P): Mark with AN_MAKEVAR.
11408 (AC_PROG_MKDIR_P): Fall back on $ac_install_sh, not $INSTALL, so
11409 that we don't require $INSTALL to be thread-safe. Move comments
11410 out of generated code. Require AC_CONFIG_AUX_DIR_DEFAULT instead
11411 of AC_PROG_INSTALL. Output a message saying that we're checking
11412 mkdir -p. Set MKDIR_P rather than mkdir_p. Do special magic for
11413 MKDIR_P instead of AC_SUBST.
11414 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE, _AC_OUTPUT_CONFIG_STATUS):
11415 Special magic for MKDIR_P, too.
11416 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Remove comment that defeated
11418 * tests/local.at (AT_CHECK_ENV): mkdir_p -> MKDIR_P.
11420 2006-05-11 Paul Eggert <eggert@cs.ucla.edu>
11422 Sync from Automake, as follows:
11424 2006-05-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11425 * config/install-sh: Initialize IFS, so field splitting isn't
11427 * config/mkinstalldirs: Likewise.
11428 * config/missing: Remove superfluous quotes. Replace all uses of
11429 `[' by `test', for consistency, and for..
11430 * config/missing (sed_minuso, sed_output): New variables.
11431 (autom4te, help2man, makeinfo): Use them. Unifies detection of
11432 `-o FILE', `--output FILE', `--output=FILE', stricter regex.
11433 Fixes `missing' to detect `--output' for help2man. Fixes
11434 PR automake/483. Report by Dennis J. Linse.
11435 (autom4te): Document in `missing --help'.
11437 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
11439 * NEWS: New macro AC_PROG_MKDIR_P. AS_MKDIR_P is now more robust.
11440 * config/install-sh: Don't use 'path' to talk about file names,
11441 as per GNU coding standards. Close a race condition reported by Ralf
11442 Wildenhues and Stepan Kasal. There is still a race condition
11443 on hosts that predate Posix 1003.1-1992, but we can't help this.
11444 Don't mishandle weird characters like space on pre-Posix hosts.
11445 Invoke mkdir at most once per dir arg on pre-Posix hosts.
11446 * doc/autoconf.texi (Programming in M4sh): Cross-reference to
11447 AC_PROG_MKDIR_P from AS_MKDIR_P.
11448 (Limitations of Usual Tools): Cross-reference to AC_PROG_MKDIR_P
11449 from mkdir. Mention that Autoconf 2.60 install-sh is safe but
11450 earlier editions are not (including Automake 1.8.3).
11451 Do not suggest mkinstalldirs for thread-safety.
11452 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Insist on an 'install'
11453 that understands -d, so that AC_PROG_MKDIR_P can fall back on $INSTALL.
11454 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Make it more robust in the
11455 presence of special characters and race conditions.
11456 * tests/local.at (AT_CHECK_ENV): Add mkdir_p to the list of variables
11457 in Autoconf's name space.
11459 2006-05-10 Bruno Haible <bruno@clisp.org>
11460 and Paul Eggert <eggert@cs.ucla.edu>

11463 from Automake with minor changes.
11464 * doc/autoconf.texi (Particular Programs): Document AC_PROG_MKDIR_P.
11466 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
11468 * config/install-sh: Update to Automake CVS version, as follows:
11469 2006-04-25 Stepan Kasal <kasal@ucw.cz>
11470 * lib/install-sh: Simplify the expr implementation of dirname.
11471 2006-04-24 Paul Eggert <eggert@cs.ucla.edu>
11472 * lib/install-sh: Handle --, and diagnose unknown options.
11474 2006-05-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11476 * tests/Makefile.am (AUTOTEST): Use `$(MY_AUTOM4TE)' instead of
11477 `./autom4te' to create `./testsuite', since the `all' target
11478 will ensure its presence, but `installcheck' should not create
11479 the uninstalled wrappers.
11481 * tests/torture.at (Unusual Automake input files): Skip if we
11482 detect automake < 1.8.
11484 2006-05-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11486 * lib/autoconf/c.m4 (AC_PROG_CC_STDC): If ac_cv_prog_cc_stdc
11487 is set to `no', then that overrides and sets ac_cv_prog_cc_c89
11488 and ac_cv_prog_cc_c99 to `no', for backward compatibility.
11491 2006-05-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11493 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Take care not to
11494 munge (multiple) white space and other oddities.
11495 * tests/torture.at (AT_CHECK_AC_ARG_VAR): Make sure to M4-escape
11496 single quotes in variable assignment.
11497 (AC_ARG_VAR, configure invocation): Adjust tests to expose this
11498 and similar failures by adding multiple spaces, tabs, and other
11499 special characters.
11500 Report and different test suggested by Francesco Romani
11501 <fromani@gmail.com> and Andrew Church <achurch@achurch.org>.
11503 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): When we escape
11504 single quotes, we only need to search for single quotes; this
11505 both simplifies the search pattern, and makes us less
11506 susceptible to `echo' variations for arguments not containing
11508 (_AC_ARG_VAR_VALIDATE): Likewise.
11510 2006-05-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11512 * doc/autoconf.texi (Special Shell Variables) <IFS>: Document
11513 `$*' and IFS concatenation issue with traditional shells and
11514 bash-2.04. Report by Seanster@Seanster.com.
11516 2006-05-03 Bruno Haible <bruno@clisp.org>
11518 * doc/autoconf.texi (Limitations of Usual Tools): Identify more
11519 precisely which Mac OS X versions have the od problem.
11521 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
11523 * doc/autoconf.texi: Use @option systematically.
11525 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
11526 and Bruno Haible <bruno@clisp.org>
11528 * doc/autoconf.texi (Limitations of Usual Tools): Add a paragraph
11530 (Integer Overflow): Mention the special case of integer division
11533 2006-05-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11535 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Cater for
11536 traditional shells like the Solaris one that do not use the
11537 first IFS character for assembling `$*'.
11538 Prompted by a related report from autoconf_bug@nro.ca.
11540 2006-05-01 Paul Eggert <eggert@cs.ucla.edu>
11541 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11543 * doc/autoconf.texi (Limitations of Builtins, Limitations of Make):
11544 Mention more problems with the -e option.
11546 2006-04-30 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11549 * doc/autoconf.texi (Systemology): Mention the Heirloom Project.
11551 * doc/autoconf.texi (Introduction, Pointers): Use `@/' liberally
11552 in URLs to improve DVI formatted output (requires texinfo 4.6).
11553 (System Services, Systemology, Shellology): Likewise.
11554 (Limitations of Usual Tools): Rewrite Mac OS X example for nicer
11557 * doc/autoconf.texi (Fortran Compiler): Do not use `@ovar' in

11560 `action-if-found' -> `action-if-true' and similarly.
11561 (Obsolete Macros): Likewise.
11562 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE): Likewise.
11563 (AC_COMPILE_IFELSE, AC_TRY_COMPILE, _AC_LINK_IFELSE)
11564 (AC_LINK_IFELSE, AC_TRY_LINK, AC_COMPILE_CHECK): Likewise.

11596 2006-04-25 Paul Eggert <eggert@cs.ucla.edu>
11598 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Don't use AS_ERROR,
11599 since as_me isn't set yet.
11601 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
11603 Prepare for deprecation of AS_BASENAME and AS_DIRNAME, and fix

11634 * lib/autoconf/headers.m4: Likewise.
11636 * doc/autoconf.texi (Run Time): Document the exit status situation
11637 with more accuracy and detail.
11639 2006-04-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11641 * doc/autoconf.texi (Introduction): The GNU Autoconf Macro
11642 Archive is not officially `GNU' any more. Update URL.
11643 (Defining Directories): Likewise
11644 * lib/autoconf/c.m4 (AC_C_RESTRICT): Update URL.
11646 2006-04-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11648 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Remove the leading
11649 newline from the `trap' code to finish `config.log'; the NetBSD
11650 /bin/sh resets the exit status after an empty command, as
11651 documented in doc/autoconf.texi.
11652 Reported by Dalibor Topic <robilad@kaffe.org>.
11654 2006-04-19 Paul Eggert <eggert@cs.ucla.edu>
11656 * doc/autoconf.texi (C Compiler): Clarify AC_C_TYPEOF.
11657 Suggested by Bruno Haible.
11659 2006-04-18 Paul Eggert <eggert@cs.ucla.edu>
11661 * configure.ac (ac_cv_sh_n_works): Don't try to test for it, since
11662 some shells (e.g., Solaris 8 /bin/sh) implement it verrrry slowly.
11663 Instead, just list the shells that we know work.
11664 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Remove 2nd arg. All uses
11665 changed. Be more cautious about the _cv_ variable.
11666 * tests/tools.at (Syntax of the shell scripts): Check the
11667 _cv_ variable once, at first, to avoid an internal autoconf error
11668 when sh -n does not work.
11670 2006-04-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11672 * lib/Autom4te/FileUtils.pm: Sync from Automake.
11674 2006-04-16 Paul Eggert <eggert@cs.ucla.edu>
11676 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Don't
11677 use ">&-" since we're only 99.999% sure that this is portable,
11678 and since the MinGW bug is fixed in a different way.
11679 * lib/autotest/general.m4 (AT_INIT): Likewise.
11681 2006-04-16 Stepan Kasal <kasal@ucw.cz>
11683 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Handle --recheck
11684 before opening config.log, to avoid hitting a bug on MinGW.
11686 2006-04-14 Paul Eggert <eggert@cs.ucla.edu>
11688 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Close
11689 AS_MESSAGE_LOG_FD before reopening it onto the log file.
11690 This works around a MinGW bug reported by Eric Paire.
11691 Make sure that all writes to the log file append to it,
11692 rather than possibly losing data.
11693 * lib/autotest/general.m4 (AT_INIT): Likewise.
11695 2006-04-14 Stepan Kasal <kasal@ucw.cz>
11697 * lib/Autom4te/FileUtils.pm (find_file): Fix a typo in the
11700 2006-04-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11704 * configure.ac (AC_INIT): Bump to 2.59d.
11706 2006-04-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11710 * Makefile.maint (news-date-check): Do not require a leading `*'
11711 before the release date in NEWS.
11713 2006-04-12 Stepan Kasal <kasal@ucw.cz>
11714 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11716 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If the templates for
11717 the instantiated file do not contain the string 'datarootdir'
11718 but contain @datadir@, @docdir@, @infodir@, @localedir@, or
11719 @mandir@, replace the reference '${datarootdir}' by the value.
11720 * tests/torture.at (datarootdir workaround): New test.
11721 * NEWS: Advertise this temporary fixup.
11722 Based on a patch by Bruno Haible, reported and analyzed by
11723 Paul Eggert and Noah Misch.
11725 2006-04-12 Eric Blake <ebb9@byu.net>
11727 * tests/autotest.at (Debugging a failed test): Fix comment.
11729 2006-04-12 Stepan Kasal <kasal@ucw.cz>
11731 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): Simplify the summary of
11732 all the changes since 2006-04-07.
11734 2006-04-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11736 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): If `ln -s file1 file2'
11737 succeeded, but `ln -s file dir' failed, take care to remove the
11738 leftover target before the next test, to prevent its spurious
11739 failure; also make sure `ln file dir' works before selecting it.
11740 Thanks to Keith Marshall for pointing this out.
11743 * lib/autotest/general.m4 (AT_INIT): Store quoted variable
11744 assignments in `at_debug_args', so that we put them correctly
11745 in the `run' script.
11746 * tests/autotest.at (Debugging a failed test): Unmark XFAIL.
11747 Reported by Eric Blake.
11749 2006-04-11 Eric Blake <ebb9@byu.net>
11751 * tests/autotest.at (AT_CHECK_AT): Add new argument, to allow
11752 top-level tests after micro-suite has been run. Used in...
11753 (Debugging a successful test, Debugging script and environment),
11754 (Debugging a failed test): ...these new tests. The first of these
11756 * lib/autotest/general.m4 (_AT_CREATE_DEBUGGING_SCRIPT): New
11757 macro, split out from...
11758 (AT_INIT): ...here, so that using -d also generates a run script.
11759 Document that -d inhibits top-level logging.
11760 * doc/autoconf.texi (testsuite Invocation): Document that -d only
11761 inhibits top-level logging; debug scripts are created.
11763 * lib/autotest/general.m4 (_AT_CHECK): Avoid syntax error on empty
11765 * tests/autotest.at (Empty test, Empty check): New test to check it.
11767 * lib/autoconf/c.m4 (AC_C_CONST, AC_C_VOLATILE): Avoid warnings
11770 2006-04-10 Stepan Kasal <kasal@ucw.cz>
11772 * tests/mktests.sh: Use "trap '' 0", not "trap 0". Do not touch
11773 the files if a problem appears. Make the empty *.at files
11774 read-only, too. Proposed by Ralf Wildenhues.
11776 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11778 * config/Makefile.am: Add comment to force updated Makefile.in.
11780 * lib/freeze.mk: Fix typo in comment. Unlike the last, white
11781 space only patch to this file, this patch causes the Makefile.in
11782 files that include freeze.mk to be updated, and thus have a
11783 newer time stamp again, which in turn makes a pristine CVS
11784 checkout have correct time stamps.
11786 * Makefile.maint (cvs-sv): New macro, to be used..
11787 (config.guess-url_prefix, config.sub-url_prefix)
11788 (texinfo.tex-url_prefix, standards.texi-url_prefix): ..here;
11789 point to CVS text checkout of Gnulib files.
11790 (copyright-check): Bump current year.
11791 (announcement): Do not hard-wire `./announce-gen'.
11792 (cvs-update): Propagate failures of `cvs' and `move-if-change'
11794 * Makefile.cfg (executable-update): Use `chmod a+x' instead of
11796 (wget_files): Update config.guess, config.sub, texinfo.tex by
11797 `wget-update', now that their URLs work again.
11799 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
11801 * doc/autoconf.texi (Particular Types): Don't use AC_CHECK_TYPE.
11802 Problem noted by Paul D. Smith.
11804 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11806 * doc/autoconf.texi: Remove unused words from word list.
11807 * .x-sc_prohibit_atoi_atof, .x-sc_space_tab, .x-sc_sun_os_names,
11808 .x-sc_trailing_space: New files.
11810 * doc/standards.texi: Sync from gnulib.
11812 * NEWS, doc/autoconf.texi (AC_LIBOBJ vs LIBOBJS): Mark
11813 `LIBOBJDIR' as experimental.
11815 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): MSYS `ln -s' fails
11816 with a target directory; it's internally implemented as `cp'
11817 anyway, but since Autoconf advertises the possibility to use
11818 a target directory when LN_S is `ln -s', we need to find out.
11819 Reported by Rolf Ebert <rolf.ebert.gcc@gmx.de> against MSYS,
11820 analyzed by Keith Marshall <keith.marshall@total.com>.
11824 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
11826 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Just output
11827 confdefs.h as-is. In general, if it has backslash-newline or the
11828 like, then it doesn't work either to sort or to remove empty
11831 2006-04-09 Stepan Kasal <kasal@ucw.cz>
11833 * tests/Makefile.am (AUTOCONF_FILES): Fix typo in the comment.
11835 2006-04-09 Alexandre Duret-Lutz <adl@gnu.org>
11837 * lib/autom4te.in (Automake-preselections): Preselect
11840 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>
11842 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Use '\'' for an
11843 apostrophe within a single-quoted string, as this is the usual
11844 tradition and is easier to read than '"'"'. Don't rely on the
11845 shell treating "$/" like '$/'. Use a more-consistent indenting
11846 style for the trap.
11848 2006-04-09 Eric Blake <ebb9@byu.net>
11850 * tests/autotest.at (Backquote command substitution),
11851 (Multiline backquote command substitution): Remove mistaken
11852 AT_NO_CMDSUBST from the 2006-03-14 patch, which was meant to be
11854 (Parenthetical command substitution, Multiline parenthetical
11855 command substitution): here.
11857 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>
11859 Import macros from gnulib (often changing their name).
11861 * NEWS: AC_C_TYPE_LONG_DOUBLE is now obsolete.

11873 (Pointers): Add Gnulib URL.
11874 (Particular Functions): Alphabetize. Add AC_FUNC_STRTOLD.
11875 (Generic Functions): Add AC_CHECK_FUNCS_ONCE. Refer to new

11881 (Generic Declarations): Add AC_CHECK_DECLS_ONCE.
11882 (Particular Structures): Add AC_STRUCT_DIRENT_D_INO,

11886 Add AC_TYPE_INT8_T, AC_TYPE_INT16_T, AC_TYPE_INT32_T, AC_TYPE_INT64_T,
11887 AC_TYPE_INTMAX_T, AC_TYPE_INTPTR_T, AC_TYPE_LONG_DOUBLE,
11888 AC_TYPE_LONG_DOUBLE_WIDER, AC_TYPE_LONG_LONG_INT, AC_TYPE_UINT8_T,
11889 AC_TYPE_UINT16_T, AC_TYPE_UINT32_T, AC_TYPE_UINT64_T,
11890 AC_TYPE_UINTMAX_T, AC_TYPE_UINTPTR_T, AC_TYPE_UNSIGNED_LONG_LONG_INT.
11891 (C Compiler): Move AC_C_LONG_DOUBLE to ...
11892 (Obsolete Macros): here. Under AC_LONG_DOUBLE, mention
11893 AC_TYPE_LONG_DOUBLE or AC_TYPE_LONG_DOUBLE_WIDER instead.
11894 (Posix Variants): Add AC_USE_SYSTEM_EXTENSIONS.
11895 (Coding Style). Don't mention m4_expand_once.
11896 * lib/autoconf/c.m4 (AC_C_LONG_DOUBLE): Implement via
11897 AC_TYPE_LONG_DOUBLE_WIDER. Now obsolete.
11898 * lib/autoconf/functions.m4 (_AH_CHECK_FUNCS): New macro.

11904 (AC_HEADER_ASSERT): New macro.
11905 (AC_HEADER_STDBOOL): Don't assume "#error" works.
11906 Catch a bug in IBM AIX xlc compiler version 6.0.0.0.
11907 Catch a bug in an HP-UX C compiler.
11908 * lib/autoconf/specific.m4 (AC_USE_SYSTEM_EXTENSIONS): New macro.
11909 * lib/autoconf/types.m4 (AC_TYPE_INTMAX_T. AC_TYPE_UINTMAX_T):

11913 (_AC_STRUCT_DIRENT, AC_STRUCT_DIRENT_D_INO, AC_STRUCT_DIRENT_D_TYPE):
11916 * tests/mktests.sh (ac_exclude_list, au_exclude_list): Do not
11917 use /^foo|bar$/, it does not mean /^(foo|bar)$/.
11919 2006-04-08 Stepan Kasal <kasal@ucw.cz>
11921 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Fix the wording
11922 of the warning introduced by the 2001-08-28 change.
11924 2006-04-08 Stepan Kasal <kasal@ucw.cz>,
11925 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11927 * lib/autoconf/general.m4 (AC_CACHE_SAVE): All `ac_cv_env_foo'
11928 variables shall be overriden by the cache.
11929 * tests/torture.at (AC_ARG_VAR): Test also with a first value
11930 that contains braces.
11932 2006-04-07 Stepan Kasal <kasal@ucw.cz>
11934 Revert the patch from 2006-04-01 and only improve
11935 _AS_DETECT_BETTER_SHELL:
11937 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Do not optimize; do not
11938 skip nonexistent directories.
11939 (_AS_DETECT_BETTER_SHELL): The optimization is moved here--try
11940 only shell candidates which exist.
11941 (AS_UNAME): No need to give three parameters to _AS_PATH_WALK.
11942 * lib/autotest/general.m4 (AT_INIT): No need to give three
11943 parameters to _AS_PATH_WALK.
11945 2006-04-07 Stepan Kasal <kasal@ucw.cz>,
11946 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11948 * bin/autoupdate.in (handle_autoconf_patches): Change the way we
11949 distinguish m4sugar macros.
11950 * tests/tools.at (autoupdating with aclocal and m4_include):
11951 New test. Bug reported by Gary V. Vaughan <gary@gnu.org>,
11952 test case by Noah Misch <noah@cs.caltech.edu>.
11954 2006-04-07 Stepan Kasal <kasal@ucw.cz>
11956 Revert my change from 2006-03-17, in other words:
11957 * lib/m4sugar/m4sh.m4 (AS_BOURNE_COMPATIBLE): Insert BIN_SH=xpg4
11959 (AS_SHELL_SANITIZE): Remove DUALCASE=1.
11960 * doc/autoconf.texi (Special Shell Variables) <BIN_SH>: Say that
11963 2006-04-07 Eric Blake <ebb9@byu.net>
11965 * doc/autoconf.texi (Programming in M4sh): Document that
11966 AS_MKDIR_P exits the script on failure.
11967 * lib/autotest/general.m4: Remove redundant AS_ERROR.
11969 2006-04-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11971 * config/elisp-comp, config/install-sh, config/mdate-sh,
11972 config/missing, config/mkinstalldirs: Sync from Automake.

11982 check, s/ac_exeext/ac_cv_exeext/. Fixes regression introduced
11985 2006-04-06 Stepan Kasal <kasal@ucw.cz>,
11986 Eric Blake <ebb9@byu.net>,
11987 Paul Eggert <eggert@cs.ucla.edu>,
11988 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11990 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): Fix the detection of
11991 whether `set' quotes correctly: redirect stderr of the tested
11992 `set', and use a subshell, for Ultrix; use `sed' instead of
11993 `grep' for zsh `set' which may write binary output; match only
11994 at the beginning of a line, to avoid false positives.
11995 In order to avoid false positives by unrelated variables with
11996 multiline content, put the dump algorithm in a subshell and
11997 unset all variables containing newlines (except some which are
11998 special to the shell). Warn about cache variables that are
12001 2006-04-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
12003 * config/config.guess, config/config.sub, config/texinfo.tex:
12004 Sync from upstream.
12006 * tests/mktests.sh: Reword comments.
12008 * tests/mktests.sh: Only skip internal macros starting with
12009 `_AC_' or `__AC_'. Noted by Stepan Kasal.
12010 Update exclusion lists for the test suite to this end:
12011 (AC_ARG_VAR): Do test this now.
12012 (AC_SEARCH_LIBS, AC_REPLACE_FUNCS): Need an argument.
12013 (AC_LINKER_OPTION): Remove (renamed to _AC_LINKER_OPTION).
12014 (AC_LIST_MEMBER_OF): Likewise (renamed to _AC_LIST_MEMBER_IF).
12015 (AC_LINK_FILES): Obsoleted since (and thus AU_DEFUN'ed).
12017 * doc/autoconf.texi (Shell Substitutions): Mention the MSYS
12018 shell issue with double-quoted command substitutions of native
12020 Reported to MSYS by Mark Cave-Ayland, to Autoconf by Keith
12023 * Makefile.maint (sc_cast_of_argument_to_free): Do not fail when
12024 no file matches the glob, discard the warning, set `nullglob'.
12025 (syntax-check): Likewise.
12026 (sc_cast_of_x_alloc_return_value): Likewise.
12027 (sc_cast_of_alloca_return_value, sc_error_exit_success)

12029 (m4-check): Likewise.
12030 (sc_system_h_headers): Do not print rule on execution.
12031 (sc_tight_scope): Do not fail for non-existing `src' directory.
12032 (sc_changelog): Skip the Copyright footer.
12033 * lib/autoconf/lang.m4: Remove trailing space.
12035 * lib/autoconf/status.m4: More replacements to
12036 <tab><space> where this makes sense.
12038 2006-04-06 Stepan Kasal <kasal@ucw.cz>
12040 * tests/Makefile.am (maintainer-check-posix):
12041 s/POSIXLY_CORRECTLY/POSIXLY_CORRECT/
12043 * lib/autoconf/status.m4 (_AC_CONFIG_FOOS): Append TAGS to
12044 ac_config_<foo>s again, sometimes normalized, sometimes not.
12045 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_LINKS):
12046 (AC_CONFIG_COMMANDS): Do not do so here.
12047 (_AC_CONFIG_REGISTER_DEST): Double quote the tags in macros _AC_LIST_TAGS
12048 and_AC_LIST_TAG_COMMANDS; fixes another regression introduced by the
12049 2005-07-25 rewrite. Noticed by Noah Misch.
12051 * lib/autoconf/general.m4 (AC_PRESERVE_HELP_ORDER): Do not define
12052 _AC_PRESERVE_HELP_ORDER, ...
12053 (AC_ARG_ENABLE, AC_ARG_WITH): ... use AC_PROVIDE_IFELSE insetad.
12055 * lib/autoconf/general.m4 (AC_ARG_VAR): Do not use m4_divert_once
12056 inside m4_expand_once; it is redundant.
12058 * lib/autoconf/general.m4 (_AC_INIT_HELP): Remove the broken support
12059 for --help from Cygnus `configure.'
12061 2006-04-06 Paul Eggert <eggert@cs.ucla.edu>
12063 * doc/autoconf.texi (C Compiler): Warn about #error. Follows up
12064 on a patch proposed by Ralf Wildenhues.
12066 2006-04-05 Paul Eggert <eggert@cs.ucla.edu>
12068 * lib/autoconf/status.m4: Replace <space>''<tab> with
12069 <tab><space> where this makes sense.
12071 2006-04-05 Howard Chu <hyc@highlandsun.com> (trivial change)
12072 Noah Misch <noah@cs.caltech.edu>
12074 * lib/autoconf/general.m4 (AC_PRESERVE_HELP_ORDER): New macro.
12075 (AC_ARG_ENABLE, AC_ARG_WITH): Adjust.

12083 lib/autoconf/types.m4, lib/autotest/general.m4,
12084 tests/mktests.sh, tests/torture.at: White space cleanup:
12085 remove some SPACE before TAB, or add quoting ('' or @&t@).

12114 Prefer 'sort -u' to 'sort | uniq'. Filter data before sorting it.
12115 Use 'comm' rather than N instances of grep; this also fixes a bug

12210 and don't call the other _AC_COMPILER_EXEEXT_* macros directly, use...
12211 (_AC_COMPILER_EXEEXT_TESTS): ... this new macro.
12212 (_AC_COMPILER_EXEEXT_O): Don't export ac_cv_exeext, it's not needed (or
12213 no longer needed) by libtool. Make it a cache check.
12214 (_AC_COMPILER_EXEEXT_CROSS): Remove the comment, it was obviously
12215 copied here by mistake.

12986 2005-10-19 Paul Eggert <eggert@cs.ucla.edu>
12988 * doc/autoconf.texi (Generating Sources): AC_LANG_PROGRAMS ->
12989 AC_LANG_PROGRAM, fixing a typo. Don't give details about
12990 the inner workings of AC_LANG_FUNC_LINK_TRY.
12991 * lib/autoconf/c.m4 (AC_LANG_CALL(C)): Reformat to match
12992 AC_LANG_FUNC_LINK_TRY. This involves returning the value returned
12993 by the function rather than ignoring it.
12994 (AC_LANG_FUNC_LINK_TRY(C)): Call the function rather than simply
12995 comparing its address. Intel's interprocedural optimization was
12996 outsmarting the old heuristic. Problem reported by
12999 2005-10-19 Stepan Kasal <kasal@ucw.cz>
13001 * lib/autoconf/general.m4 (AC_SUBST): Remove an obsolete comment.
13003 2005-10-05 Paul Eggert <eggert@cs.ucla.edu>
13005 * lib/m4sugar/m4sugar.m4 (_m4_map): New macro.
13006 (m4_map, m4_map_sep): Use it. Handle the empty list correctly.
13008 2005-10-04 Stepan Kasal <kasal@ucw.cz>
13010 * lib/autotest/general.m4 (AT_INIT): Really make the subtree writable
13011 before removing it (chmod -R u+rwx); there are three instances of this.
13013 2005-10-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
13014 Stepan Kasal <kasal@ucw.cz>
13016 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Balance parentheses.
13017 * lib/autotest/general.m4 (AT_INIT): If the test dir already exists,
13018 make its content writable before removing it. Remove an errorneous
13019 comment from the end, where the logs of the failed tests are copied
13020 to the main log file.
13022 2005-09-27 Stepan Kasal <kasal@ucw.cz>
13024 * tests/semantics.at (AC_C_BIGENDIAN): Pass --force to autoheader,
13025 in case the computer is too quick. Double quote the configure.ac
13028 * tests/local.at (AT_CHECK_AUTOCONF): Always pass --force to prevent
13029 problems if the testsuite were running too fast.
13031 2005-09-18 Paul Eggert <eggert@cs.ucla.edu>
13033 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Look for X11/Xlib.h
13034 and XrmInitialize rather than X11/Intrinsic.h and XtMalloc
13035 (which belong to Xt, not X itself). See Debian bug 327655.
13036 * NEWS: Mention this.
13038 2005-09-07 Stepan Kasal <kasal@ucw.cz>
13040 * lib/autoconf/c.m4 (AC_LANG_SOURCE(C)): Remove an incorrect comment.
13042 2005-09-06 Paul Eggert <eggert@cs.ucla.edu>
13044 * config/move-if-change: Don't output "$2 is unchanged";
13045 suggested by Ben Elliston. Handle weird characters correctly.
13047 2005-09-06 Stepan Kasal <kasal@ucw.cz>
13049 * lib/autoconf/libs.m4 (AC_SEARCH_LIBS): Merge the two AC_LINK_IFELSE
13050 calls, so that the final expansion of this macro is shorter.
13051 Create the conftest.$ac_ext outside the `for' loop, to speed the run.
13052 Do not use `break' in the argument to AC_LINK_IFELSE, it would skip
13053 the cleanup there. Use AS_VAR_* macros, to be more general.
13054 * tests/semantics.at (AC_SEARCH_LIBS): Check for the cleanup.
13056 * lib/autoconf/general.m4: Use AS_IF where appropriate.
13058 * lib/m4sugar/m4sh.m4 (AS_IF): Use m4_default.
13060 2005-09-01 Stepan Kasal <kasal@ucw.cz>
13062 * doc/autoconf.texi (Configuration Headers): Add an index entry
13065 2005-08-26 Pavel Roskin <proski@gnu.org>
13067 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): Use shell variable
13068 XMKMF to locate xmkmf. Make XMKMF precious. Export CC when
13071 2005-08-26 Paul Eggert <eggert@cs.ucla.edu>
13073 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE):
13074 The previous patch didn't work, so try a better one.
13076 2005-08-26 Stepan Kasal <kasal@ucw.cz>
13078 * doc/autoconf.texi (Programming in M4sh) <AS_TR_CPP>: Fix m4 quoting
13079 in the example. Reported by Bruno Haible.
13080 <AS_TR_SH>: Likewise. Also modify the example to be more convincing:
13081 "if $undefined_var;" succeeds with my shell.
13083 * lib/autoconf/general.m4 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST,
13084 AC_CANONICAL_TARGET): Define by AC_DEFUN, no need to use AC_DEFUN_ONCE;
13085 but change the m4_divert_text to m4_divert_once.
13087 2005-08-25 Paul Eggert <eggert@cs.ucla.edu>
13089 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE):
13090 Work around bug in Solaris /usr/xpg4/bin/awk.
13091 The bug is present in at least Solaris 8 through 10.
13093 2005-08-24 Stepan Kasal <kasal@ucw.cz>
13095 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Simplify; rejecting
13096 some evil values and relying on the fact that $* concatenates the
13097 parameters by the first character from IFS.
13099 2005-08-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
13100 Stepan Kasal <kasal@ucw.cz>
13102 * lib/autoconf/status.m4 (_AC_CONFIG_REGISTER_DEST): When the
13103 first header appears, define AH_HEADER.
13104 * doc/autoconf.texi (Configuration Headers): Document AH_HEADER.
13105 Update limitations about when to call AC_CONFIG_HEADERS.
13106 (Configuration Commands): Document that AC_CONFIG_COMMANDS_PRE
13107 parameter can call AC_SUBST, AC_DEFINE, or AC_CONFIG_FOOS; explain
13108 that AC_CONFIG_COMMANDS_PRE and AC_CONFIG_COMMANDS_POST are not
13109 ``Configuration Actions''; fix their index entries.
13111 * lib/autotest/general.m4 (AT_INIT): Process multiple keywords
13112 options correctly. Process N-M as M-N if M is smaller than N.
13113 Process ranges correctly so that N-N will run only N.
13114 Sort and uniquify the tests that will be run. If there is more
13115 than one test, reinsert the banners for the tests.
13116 * tests/autotest.at (Keywords): Unmark XFAIL.
13118 2005-08-23 Stepan Kasal <kasal@ucw.cz>
13120 * lib/autoconf/general.m4 (_AC_DEFINE_Q): Strip the parameter list
13121 before passing the macro name to AH_TEMPLATE.
13123 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): config.status
13124 now opens log after option processing; in particular, --version
13125 and --help do not touch config.log.
13127 * Makefile.maint: Revert the change from 2005-08-12.
13129 2005-08-22 Stepan Kasal <kasal@ucw.cz>
13131 * lib/autoconf/general.m4 (AC_ARG_ENABLE, AC_ARG_WITH): Factor out
13133 (_AC_ENABLE_IF, _AC_ENABLE_IF_ACTION): ... these new macros.
13135 2005-08-21 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
13137 * doc/autoconf.texi (Using Autotest, testsuite Scripts)
13138 (Autotest Logs, Writing testsuite.at, testsuite Invocation):
13141 * doc/autoconf.texi (Defining Symbols, Changed Results):
13142 Prepend to LIBS, not append, in examples.
13144 2005-08-16 Stepan Kasal <kasal@ucw.cz>
13146 When building in place, set srcdir="."; suggested by Tim Van Holder.
13148 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Do this; to recognize
13149 build in place, we need ac_pwd, and thus have to AC_REQUIRE ...
13150 (_AC_INIT_DIRCHECK): ... this macro and AC_DEFUN both of them.
13151 * lib/autoconf/status.m4 (_AC_SRCDIRS): Fix a comment: srcdir="."
13152 does not mean "no --srcdir option".
13154 2005-08-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
13156 * tests/autoscan.at (autoscan): New file.
13157 * tests/suite.at: Use it.
13158 * tests/Makefile.am (TESTSUITE_HAND_AT): Add it.
13159 Reported against Libtool by Gideon Go <gideon.go@gmail.com>.
13161 * tests/autotest.at (Keywords): Test keywords combinations.
13163 2005-08-12 Stepan Kasal <kasal@ucw.cz>
13165 * Makefile.maint (GZIP_ENV): When checking the help text of gzip,
13166 add "2>&1"; gzip 1.2.4 prints help on stderr.
13168 2005-07-27 Stepan Kasal <kasal@ucw.cz>
13170 * lib/autotest/general.m4 (_AT_DECIDE_TRACEABLE): The symbol at_reason
13171 was pushdef'ed twice while popped only once. Push it only once.
13172 (_AT_CHECK): Cosmetic changes to the "case $at_status" command.
13174 2005-07-26 Stepan Kasal <kasal@ucw.cz>
13176 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): The message is now
13177 prefixed by mere "===", not "configure: === ".
13179 2005-07-25 Paul Eggert <eggert@cs.ucla.edu>
13181 * Makefile.maint: Update from Bison.
13183 * lib/m4sugar/m4sugar.m4 (m4_strip): Comment fix---change tab to
13184 "<tab>" in comment, so that the point is understandable.
13186 2005-07-25 Stepan Kasal <kasal@ucw.cz>
13188 Rewrite substantial part of lib/autoconf/status.m4.
13189 The main change is that CONFIG_FILES, CONFIG_HEADERS, CONFIG_LINKS,
13190 and CONFIG_COMMANDS are not processed in four separate loops.
13191 Instead, there is one main loop. This alows that the common code
13192 is expanded only once, thus config.status (and configure) is smaller.
13194 The registration mechnism in AC_CONFIG_FILES and cousins also changed;
13195 the AC_LIST_FILES and cousins macros are no longer used.
13197 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES, _AC_OUTPUT_HEADERS,
13198 _AC_OUTPUT_LINKS, _AC_OUTPUT_COMMANDS): Renamed to ...
13199 (_AC_OUTPUT_FILE, _AC_OUTPUT_HEADER, _AC_OUTPUT_LINK,
13200 _AC_OUTPUT_COMMAND): ..., respectively. These macros no longer
13201 contain the initialization, nor the for loop, nor the associated
13202 commands; all these go to ...
13203 (_AC_OUTPUT_MAIN_LOOP): ... this new macro, called from
13204 _AC_OUTPUT_CONFIG_STATUS.
13205 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST, _AC_CONFIG_SPLIT_FILE_IN):
13206 Nuked; the code was merged into _AC_OUTPUT_MAIN_LOOP.
13207 (_AC_OUTPUT_FILE): The creation of the sed script ...
13208 (AC_OUTPUT): ... and the setup of ac_vpsub goes to ...
13209 (_AC_OUTPUT_FILES_PREPARE): ... a new macro, also called from
13210 _AC_OUTPUT_MAIN_LOOP.
13211 (_AC_CONFIG_FILES, _AC_CONFIG_HEADERS, _AC_CONFIG_LINKS,
13212 _AC_CONFIG_COMMANDS): Use ...
13213 (_AC_CONFIG_FOOS): ... this new macro, which uses these ...
13214 (_AC_CONFIG_REGISTER, _AC_CONFIG_REGISTER_DEST): ... new macros.
13215 (_AC_CONFIG_FILE, _AC_CONFIG_HEADER, _AC_CONFIG_LINK,
13216 _AC_CONFIG_COMMAND, _AC_CONFIG_DEPENDENCIES): No longer needed.
13217 (_AC_CONFIG_DEPENDENCY): Update, it uses these ...
13218 (_AC_CONFIG_DEPENDENCY_DEFAULT, _AC_FILE_DEPENDENCY_TRACE_COLON):
13220 (_AC_CONFIG_UNIQUE): Update.
13221 (AC_LIST_FILES, AC_LIST_HEADERS, AC_LIST_LINKS, AC_LIST_COMMANDS):
13222 Replaced by this ...
13223 (_AC_LIST_TAGS): ... new common macro.
13224 (AC_LIST_FILE_COMMANDS, AC_LIST_HEADER_COMMANDS, AC_LIST_LINK_COMMANDS,
13225 AC_LIST_COMMAND_COMMANDS): Replaced by this ...
13226 (_AC_LIST_TAG_COMMANDS): ... new common macro.
13227 (_AC_CONFIG_COMMANDS_INIT): Moved top to the `registration' section;
13228 this didn't belong to the `config commands' section.
13229 (_AC_OUTPUT_COMMANDS_INIT): Don't initialize, m4_ifdef is our friend.
13230 (AC_CONFIG_COMMANDS_PRE, AC_OUTPUT_COMMANDS_PRE,
13231 AC_CONFIG_COMMANDS_POST): Moved to a new section, these didn't belong
13232 to the `config commands' section either.
13233 (AC_CONFIG_SUBDIRS): Don't touch diversion DEFAULTS.
13234 (_AC_LIST_SUBDIRS): Don't initialize, m4_ifdef is our friend.
13236 ... and many changes to the comments nearby.
13238 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): At the end of the day,
13239 set ac_subdirs_all='_AC_LIST_SUBDIRS'.
13240 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
13241 AC_CONFIG_COMMANDS(command:input,...) is no longer allowed.
13242 (#define header templates): The comment at the top of the generated
13243 header now includes the name(s) of the source file(s).
13245 Several unrelated small changes:
13247 * lib/autoconf/general.m4 (AC_CACHE_VAL): Be didactic, quote the first
13248 parameter to AC_DIAGNOSE.
13249 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS): Likewise.
13250 (_AC_LINK_FILES_CNT): Don't AU_DEFUN this; it causes confusing messages
13251 with autoupdate; use m4_define_default inside AU_DEFUNed AC_LINK_FILES.
13252 (AC_OUTPUT): In the compatibility code, use m4_ifvaln, to be consistent
13253 with AU::AC_OUTPUT.
13254 (AU::AC_OUTPUT): Don't double-quote $2 and $3, the compatibility code
13255 in AC_OUTPUT doesn't double-quote it either.
13256 * tests/tools.at (autoupdate): AU::AC_OUTPUT no longer double-quotes the
13259 2005-07-10 Stepan Kasal <kasal@ucw.cz>
13261 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Document which
13262 versions of Portland Group compiler produce single- and double-quoted
13263 -cmdline argument. Reported by Steven G. Johnson <stevenj@fftw.org>
13264 and Ole Holm Nielsen <Ole.H.Nielsen@fysik.dtu.dk>.
13266 2005-07-07 Paul Eggert <eggert@cs.ucla.edu>
13268 * tests/local.at (AT_CONFIG_CMP): Ignore lines like "LIBS=''" too.
13269 This is a corrected version of yesterday's patch.
13271 2005-07-07 Stepan Kasal <kasal@ucw.cz>
13273 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Report the full
13274 path, too; insert a "===" to emphasize the line.
13276 * lib/autoconf/general.m4 (AC_CANONICAL_BUILD): Rename
13277 ac_cv_build_alias to ac_build_alias.
13278 (AC_CANONICAL_HOST, AC_CANONICAL_TARGET): Simplify.
13280 On 2005-02-24, an unintentional AC_SUBST([CC]) was introduced; this
13281 change eliminates it. Problem reported by Alexandre Duret-Lutz.
13282 * lib/autoconf/general.m4 (_AC_ARG_VAR_PRECIOUS): Move the AC_SUBST ...
13283 (AC_ARG_VAR): ... here.
13284 (_AC_INIT_PREPARE): Call AC_SUBST for build_alias, host_alias and
13287 Keep a list of all precious variables and process them with one simple
13288 for loop, instead of expanding all commands, or, OTOH, complicated
13289 processing of output of "set".
13290 * lib/autoconf/general.m4 (_AC_ARG_VAR_PRECIOUS): Acumulate the
13291 variable names in new macro...
13292 (_AC_PRECIOUS_VARS): ... which will be assigned to ac_precious_vars.
13293 (_AC_ARG_VAR_STORE): New macro which writes to diversion PARSE_ARGS
13294 a loop to assign all ac_env_* and ac_cv_env_* variables.
13295 (_AC_ARG_VAR_VALIDATE): Use shell variable ac_precious_vars, divert
13297 (_AC_INIT_DEFAULTS): At the end, if _AC_PRECIOUS_VARS is set, assign
13298 its value to shell variable ac_precious_vars and call
13299 _AC_ARG_VAR_STORE and _AC_ARG_VAR_VALIDATE.
13300 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Don't call
13301 _AC_ARG_VAR_VALIDATE.
13303 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Move AC_LANG_PUSH(C)
13304 and the AC_SUBSTs ...

13308 the ac_subst_files section in config.log.

13316 * lib/autoconf/c.m4 (AC_C_TYPEOF): New macro.
13317 * tests/c.at (C keywords): Test AC_C_TYPEOF.
13319 Fix problems reported by Nicolas Joly.

13321 * tests/local.at (AT_CONFIG_CMP): Ignore lines like "LIBS=''" too.
13322 They are generated by the Tru64 v5.1B shell.
13324 2005-07-05 Stepan Kasal <kasal@ucw.cz>
13326 Fix my changes from 2005-07-01; reported by Noah Misch.
13327 * lib/autoconf/status.m4 (_AC_CONFIG_DEPENDENCIES): Fix the
13328 description, the macro now accepts only a single tag.
13329 (_AC_CONFIG_UNIQUE): Likewise; s/AC_File/[$1]/
13331 Fix cases when the varsions of Autoconf and Autotest don't match.
13332 Reported by Noah Misch.
13333 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Set also
13334 at_top_builddir, for compatibility with older autotest.
13335 * lib/autotest/general.m4 (AT_INIT): If at_top_build_prefix
13336 is not set, use at_top_builddir, for compatibility with older
13337 versions of autoconf.
13339 2005-07-04 Paul Eggert <eggert@cs.ucla.edu>
13341 * bin/autom4te.in ($m4): Catch usages like --nesting-limit=2048.
13342 Problem reported by Patrick Welche.
13344 2005-07-03 Paul Eggert <eggert@cs.ucla.edu>
13346 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Use &, not |, in
13347 sed substitution command, so that we allow | in program prefixes
13348 and program suffixes. (& is a problem anyway; we're not fixing
13350 * lib/autoconf/status.m4 (AC_CONFIG_FILES): Likewise, for
13351 configure_input, top_builddir, srcdir, etc.
13352 * lib/autotest/general.m4 (AT_INIT): Likewise, for
13353 PATH_SEPARATOR in AUTOTEST_PATH.
13355 2005-07-02 Alexandre Duret-Lutz <adl@gnu.org>
13357 * lib/autoconf/general.m4 (AC_SITE_LOAD): Rewrite the
13358 for loop over config.site files using `set', to allow
13359 directory names containing IFS characters.
13361 2005-07-01 Paul Eggert <eggert@cs.ucla.edu>
13363 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Remove the tests for
13364 directories with weird names. Apparently some people like living
13365 on the edge. However, improve the test that "pwd" actually does
13366 report a name for the working directory.
13367 * NEWS: Remove the claim that we test for funny chars in dir names.
13369 2005-07-01 Stepan Kasal <kasal@ucw.cz>
13371 * lib/autoconf/general.m4 (AC_FOREACH): Make obsolete; it's
13373 * lib/m4sugar/m4sugar.m4 (m4_foreach_w): ... by this new macro.
13374 * lib/autoconf/status.m4 (_AC_CONFIG_DEPENDENCIES, _AC_CONFIG_UNIQUE):
13375 Now accept a single tag, not whitespace separated list.

13381 about #include <config.h>.
13382 (Generic Functions): Mention the Gnulib project.
13383 (Limitations of Usual Tools) <sed>: Another minor rephrasing.
13385 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Use a here
13386 document to output the default config_* lists to config.status.
13387 Don't recognize option --file, if the functionality is not there.
13388 Likewise for --header; moreover, recognize --he and --h as shortcuts
13389 for --help in that case.
13391 * lib/autoconf/status.m4: Fix the order of the "sections", so that it
13392 matches the order of execution. No code changed.
13394 2005-06-30 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
13396 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Fix also for
13397 single-quoted -cmdline argument in Portland Group compiler.
13398 Reported against LAM by Ole Holm Nielsen <Ole.H.Nielsen@fysik.dtu.dk>.
13400 2005-06-30 Alexandre Duret-Lutz <adl@gnu.org>

13404 2005-06-29 Stepan Kasal <kasal@ucw.cz>
13406 * doc/autoconf.texi (File Descriptors): ksh doesn't pass open file
13407 descriptors to child processes; reported by Norman Gray.
13409 2005-06-29 Stepan Kasal <kasal@ucw.cz>
13411 * lib/autoconf/general.m4 (AC_ARG_VAR): Move next to _AC_ARG_PRECIOUS.
13413 * lib/autoconf/general.m4 (AC_SUBST_TRACE): New macro, to be traced
13414 instead of AC_SUBST; proposed by Alexandre Duret-Lutz.
13415 (AC_SUBST): Call it.
13416 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Call AC_SUBST_TRACE for
13417 the directory specific variables; but don't call it for configure_input.
13419 2005-06-28 Derek Price <derek@ximbiot.com>
13421 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: Reword recent
13424 2005-06-23 Paul Eggert <eggert@cs.ucla.edu>
13426 * NEWS: Don't worry about spaces in bindir etc. Only srcdir and working
13427 directory have inherent problems with special characters like spaces,
13428 due to limitations in Make syntax. Problem reported by Alexandre
13430 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Implement the above.
13431 Also, fix Tru64 porting problem with shell patterns,
13432 reported by Ralf Wildenhues.

13442 Fix some more shell quoting problems. Prompted by a bug report
13443 from Justace Clutter.
13444 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Put name of invalid
13445 variable into diagnostic. Make the diagnostic an error, not a warning,
13446 because we really don't support spaces and suchlike in dir names.
13447 (_AC_INIT_SRCDIR): Allow special characters in $ac_unique_file.
13448 Don't worry about backslashes in srcdir; it can't happen now.

13457 * tests/atlocal.in: Propagate $EGREP and $SED.
13458 * tests/local.at (AT_CHECK_ENV): Use $EGREP, not $GREP -E.
13459 (AT_CONFIG_CMP): Use sed instead of grep plumbing.
13461 * doc/autoconf.texi (Limitations of Usual Tools) <grep>: Mention
13462 that '\|' is not allowed in BREs; recommend using newline separated
13463 list of patterns instead of multiple -e options.
13465 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Remove an old comment.
13467 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Use AC_SUBST/2.

13473 2005-06-21 Stepan Kasal <kasal@ucw.cz>
13475 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: Document that
13476 b, t, r, w commands require single space, while : cannot have any.
13477 (Special Shell Variables): Fix sed code this in the example.
13478 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Likewise; and fix a typo.
13479 * lib/autotest/general.m4 (AT_ARG_OPTION): Fix typo in the description.
13481 * lib/m4sugar/m4sugar.m4 (m4_split): If the parameter is empty,
13482 expand to the empty list. Don't use two pairs of m4_changequote,
13483 it's not necessary.
13485 2005-06-20 Derek Price <derek@ximbiot.com>
13487 * lib/m4/programs.m4 (AC_PROG_YACC): Declare YACC & YFLAGS precious.
13489 2005-06-17 Paul Eggert <eggert@cs.ucla.edu>
13491 * lib/m4sugar/m4sh.m4 (as_awk_strverscmp): Port to Solaris /bin/awk.
13492 * doc/autoconf.texi:
13493 Don't mention Solaris versions so much, if a
13494 problem is common to all extant versions of Solaris. Say "SunOS
13495 4" instead of "SunOS" for SunOS 4.
13496 (awk): Mention more of the limitations of traditional Awk.
13497 (cat): Don't talk about cat -v.
13499 2005-06-16 Paul Eggert <eggert@cs.ucla.edu>
13501 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE): New macro.
13502 (AS_VERSION_COMPARE): New macro. The API is taken from CVS,
13503 but the implementation is entirely different and is designed
13504 to be compatible with glibc strverscmp.
13505 * tests/m4sh.at (AS_VERSION_COMPARE): New test.
13507 * doc/autoconf.texi (Limitations of Usual Tools): Mention expr bug
13508 on Mac OS X 10.4 reported by Peter O'Gorman in:

13510 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT):
13511 Use shell builtins rather than 'expr', to work around expr bug.
13513 2005-06-10 Paul Eggert <eggert@cs.ucla.edu>
13515 * doc/autoconf.texi: "filesystem" -> "file system".
13516 "behaviour" -> "behavior".
13517 Warn about \(...\)* in Solaris sed (written by Ralf Menzel).
13518 * lib/autoconf/general.m4: Omit blank after ":" sed command,
13520 * lib/m4sugar/m4sh.m4: Likewise.
13521 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Work around problem
13522 with Solaris sed. Fix by Ralf Menzel and Stepan Kasal.
13524 * man/Makefile.am (MOSTLYCLEANFILES): Add $(srcdir)/*.t.
13525 (.x.1): Ignore the time stamp in the .TH line when deciding whether
13526 to update the man page. That way, we don't have to check in new
13527 man pages every month.
13529 * lib/m4sugar/m4sh.m4 (AS_VAR_TEST_SET): Work even if $1 contains
13530 quotes and backslashes. Patch from Derek Price.

13539 * lib/autotest/general.m4 (AT_INIT): Don't accept Solaris 9's diff
13540 -u, since it outputs chatter if the input files are the same.
13541 Problem reported by Ralf Menzel.
13543 2005-06-08 Derek Price <derek@ximbiot.com>
13545 * lib/m4sugar/m4sugar.m4: Undefine include & sinclude rather than
13546 renaming them since they are about to be redefined anyhow.
13548 2005-06-08 Derek Price <derek@ximbiot.com>
13550 * doc/autoconf.texi (Redefined M4 Macros): Add index entries for most
13551 redefined M4 macros to this node. Document m4_include & m4_sinclude.
13552 Move m4_undefine to alphabetical order.
13554 2005-06-07 Paul Eggert <eggert@cs.ucla.edu>
13556 * README: Recommend GNU M4 1.4.3 or later.
13557 * doc/autoconf.texi (Introduction): Likewise.
13558 Reword to avoid some formatting glitches.
13559 Use "#!/bin/sh", not "#! /bin/sh"; the space isn't needed these days.
13560 Clarify explanation of HP compiler bug.
13561 Redo example output tp match current CVS snapshot.
13562 Use @example.org in email addresses when the examples
13563 might get inadvertently cut-and-pasted into user code.
13564 Remove example of autom4te usage that doesn't seem to work now.
13565 Use modern AC_INIT (except when the example is meant to be
13566 shown with Autoconf 2.13).
13567 Update ksh info for Solaris 9 and later.
13569 Modernize description of Automake versions a bit.
13570 Don't claim a future version of Autoconf is near.
13571 * doc/install.texi: Reword to avoid some formatting glitches.
13573 2005-06-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
13575 * doc/autoconf.texi: Add [] to examples, so that the manual
13576 follows its own advice about quoting better.
13577 Reword to avoid some formatting glitches.
13578 * doc/installt.exi: Reword to avoid some formatting glitches.
13580 * doc/autoconf.texi (Limitations of Builtins) <case>: Mention
13581 Tru64 ksh pattern matching bug. Reported against Libtool by
13582 Albert Chin <libtool@mlists.thewrittenword.com> and
13583 Nicolas Joly <njoly@pasteur.fr>.
13585 2005-06-06 Stepan Kasal <kasal@ucw.cz>
13587 m4_cdr of one-member list was [[]] (one-member list containing an
13588 empty string) instead of [] (an empty list. Callers were skewed to
13589 match this misbehaviour. As a consequence of this:
13590 - m4_foreach([x], [], [foo]) expanded to `foo', while
13591 - the expansion of m4_foreach([x], [[]], [foo]) was empty.
13592 This bug has been fixed:
13594 * lib/m4sugar/m4sugar.m4 (m4_cdr): If only one argument is given,
13595 expand to an empty string; print error msg if called without
13597 (m4_foreach, m4_map, m4_map_sep): Don't expect the previous
13598 misbehaviour; handle [] and [[]] correctly.
13600 2005-06-06 Stepan Kasal <kasal@ucw.cz>
13602 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Nuke ac_max_here_lines.
13603 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Simplify the sed
13604 scripts created and the loop applying them, use _AC_SED_CMD_LIMIT.
13606 2005-06-06 Ralf Menzel <menzel@ls6.cs.uni-dortmund.de> (trivial change)
13608 * doc/autoconf.texi (Limitations of Usual Tools): Solaris' awk cannot
13609 swallow records with more than 99 fields.
13610 * lib/autotest/general.m4 (AT_INIT): Use the awk builtin `split' to
13611 parse the long line.
13613 2005-06-04 Stepan Kasal <kasal@ucw.cz>
13615 * doc/autoconf.texi (Limitations of Usual Tools): AIX awk cannot
13616 swallow literals longer than 399. Reported by Ralf Wildenhues.
13617 * lib/autotest/general.m4 (AT_INIT): Pass $at_groups though stdin,
13618 to workaround this limitation.
13620 2005-06-03 Steven G. Johnson <stevenj@alum.mit.edu>
13622 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Find g95 in addition
13623 to gfortran, and make these the first two compiler names
13624 checked (following the general autoconf preference for gcc).
13626 2005-06-03 Stepan Kasal <kasal@ucw.cz>
13628 * tests/Makefile.am (check_SCRIPTS): Set to $(wrappers).
13629 (DISTCLEANFILES): Remove $(check_SCRIPTS).
13630 (testsuite): Make sure autotest.m4f is up-to-date before using it.
13632 2005-06-02 Paul Eggert <eggert@cs.ucla.edu>
13634 * lib/autotest/general.m4 (AT_INIT): Don't create a regular
13635 expression of unbounded size when processing the --list
13636 option. This runs afoul of a limit of 399 bytes per regular
13637 expression on AIX. Problem reported by Ralf Wildenhues.
13639 2005-06-01 Paul Eggert <eggert@cs.ucla.edu>
13641 * NEWS: Note yesterday's changes to AC_SUBST and AC_SUBST_FILE.
13642 * doc/autoconf.texi (Particular Headers): Reword example
13643 for multiline stdbool replacement.
13644 (Setting Output Variables): Reword text a bit. Don't
13645 give all the details about |#_!!_#|.
13646 Reword description of line replacement.
13648 2005-05-31 Dan Manthey <dan_manthey@partech.com>
13650 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Output variables may
13651 now contain newlines, and substituted files must be referenced on
13652 a line alone; the sed scripts to substitute them are now very
13654 (_AC_SED_CMD_LIMIT): Added; single place to store limit on how many
13655 commands can be put in a sed script portably.
13656 * doc/autoconf.texi (Setting Output Variables): Document above
13657 changes. (Particular Header Checks) <AC_HEADER_STDBOOL>: Give exaple
13658 use of multiline substitution.

13668 * tests/local.at: Don't attempt to check for negated character
13669 classes in shell scripts. The test was too brittle.
13671 2005-05-25 Stepan Kasal <kasal@ucw.cz>
13673 * bin/autoconf.as: Don't use "shift 2"; it's not portable enough.
13674 * doc/autoconf.texi (Limitations of Builtins): Document this
13677 2005-05-24 Stepan Kasal <kasal@ucw.cz>
13679 * lib/m4sugar/m4sh.m4 (_AS_ECHO_LOG): New macro to factor out
13680 common code; used in many places in the tree.

13682 (_AS_ECHO_UNQUOTED): Move the macro lower; no code change.
13684 * lib/m4sugar/m4sugar.m4 (m4_ifset): Use m4_ifval.
13686 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Merge the two error
13687 messages when ac_unique_file is not found.
13688 (AC_CONFIG_MACRO_DIR): Simplify the `if' at the end.
13689 (AC_MSG_CHECKING, AC_MSG_RESULT): Put braces around the two echo
13690 commands, for consistency with AC_MSG_ERROR and such.
13692 * bin/autoconf.as: Make more use of "shift 2" in option processing.
13694 * bin/Makefile.am: Merge the two rules for creating scripts.

13702 2005-05-20 Stepan Kasal <kasal@ucw.cz>
13704 * NEWS: @top_builddir@ is now a dirname, ac_top_builddir will follow.
13705 * lib/autoconf/status.m4 (_AC_SRCDIRS): Rename ...
13706 (ac_top_builddir): ... this ...
13707 (ac_top_build_prefix): ... to this; the old name is also kept, for
13708 backward compatibility.
13709 (ac_top_builddir_sub): New variable, without the trailing slash,
13711 (_AC_OUTPUT_FILES): s/@top_builddir@/$ac_top_builddir_sub/
13712 * doc/autoconf.texi (Configuration Actions): Rename
13713 ac_top_builddir to ac_top_build_prefix.
13714 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Rename

13725 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Don't m4_quote the second
13726 argument to m4_foreach. I guess it was necessary in the past,
13727 but I think it's a no-op now.
13729 2005-05-17 Stepan Kasal <kasal@ucw.cz>
13731 * lib/autoconf/general.m4 (_AC_INIT_HELP): Merge two consecutive
13732 ``cat <<_ACEOF'' commands to one.
13733 (_AC_CANONICAL_SPLIT): Use expr, not ``echo|sed.''
13734 * lib/autoconf/status.m4: On various places, use expr instead of
13736 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST):
13737 (_AC_CONFIG_SPLIT_FILE_IN): New macros, to factor out common code.
13738 * lib/autotest/general.m4 (AT_INIT): Use expr to get the numbers from
13740 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Use awk to search for
13741 the wrong patterns between ``case'' and ``esac.'' The previous
13742 code had false positives.
13744 2005-05-14 Alexandre Duret-Lutz <adl@gnu.org>
13746 * lib/autoconf/functions.m4 (_AC_LIBOBJ_ALLOCA): Prepend ${LIBOBJDIR},

13811 quoting rules. Problems noted by Stepan Kasal.
13812 Also, throughout this document, be more careful about white space.
13813 "blank", "white space", and "space" all have different meanings
13814 and we should be careful to say what we mean.

13853 * doc/autoconf.texi (External Software): Replace AC_DEFINE_UNQUOTED
13854 by AC_DEFINE; it was a mistake.

13865 * lib/m4sugar/m4sh.m4 (AS_HELP_STRING): Add a FIXME about quadrigraphs.
13866 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Likewise; and rephrase the
13867 comment and reduce m4_default([foo], []) to [foo].
13868 (m4_strip): Update the explanation.

13872 * lib/autoconf/general.m4 (_AC_INIT_PREPARE, _AC_RUN_IFELSE):
13873 Remove core.conftest.* too; it's generated by Tru64 5.1.
13874 Problem reported by Jennis Pruett.
13875 * lib/autoconf/functions.m4
13876 (AC_FUNC_SETVBUF_REVERSED, AC_FUNC_UTIME_NULL):

13902 as well as configure.in. Problem reported by Gregorio Guidi.
13904 2005-04-10 Paul Eggert <eggert@cs.ucla.edu>
13906 * doc/autoconf.texi (Particular Functions): Use gnulib's current

13920 fails if %s isn't supported. Problem reported by Ralf Wildenhues.
13922 2005-03-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
13924 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS):
13925 Merge `-z option' as well for the benefit of Solaris link flags. Pass
13926 whole-archive (-zallextract, -zdefaultextract) options in the hope of
13927 unique libraries, for the Sun Fortran 95 8.0 compiler. Bug reported
13928 against Libtool by Yury Puhalsky <pooh@cryptopro.ru>.

13932 * NEWS: The configure command now warns you if you attempt to use
13933 a directory whose name contains a special character like space,
13935 * doc/autoconf.texi (Installation Directory Variables): Allow
13936 "," in file names. Do not use \@; it's not a portable regexp.

13949 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Propagate
13950 ac_pwd, and quote srcdir.
13951 * lib/autotest/general.m4 (AT_INIT): Quote file name args.
13953 * doc/autoconf.texi: Fix some systematic formatting problems.
13954 ".)" needs a following @: if not at the end of a sentence, and
13955 similarly for "!)". "etc." should be preceded by a comma.
13956 "n-th" -> "@var{n}th". pdksh is still buggy, so update its date.
13958 2005-03-22 Bruno Haible <bruno@clisp.org>
13960 * doc/autoconf.texi (Input): Mention that AC_CONFIG_AUX_DIR's
13961 argument is often called 'build-aux'.
13963 2005-03-07 Stepan Kasal <kasal@ucw.cz>
13965 * doc/autoconf.texi (Quotation Rule Of Thumb): Mention that the
13966 macro AC_TRY_LINK is obsolete.
13967 (Installation Directory Variables): Change `AC_OUTPUT_FILES' to
13970 2005-02-24 Stepan Kasal <kasal@ucw.cz>
13972 * lib/autoconf/c.m4 (AC_PROG_CC): Be more careful to skip
13973 `/usr/ucb/cc'; use `cl.exe' to distinguish the MS compiler
13974 from a Common Lisp's `cl'.
13975 (AC_PROG_CXX): Behave according to the documentation: don't
13976 search for $ac_tool_prefix$CCC and $CCC, just set CXX=$CCC;
13977 make the variable CCC precious; use `cl.exe', not `cl'.
13979 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
13980 Alexandre Duret-Lutz <adl@gnu.org>
13982 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin from
13983 /dev/null, as "configure" shouldn't read stdin, and this insulates
13984 us from problems (e.g., when testing for "cl"). Also, do this
13985 redirection before invoking "hostname" or "uname", and keep the
13986 original input stream available via...
13987 (AS_ORIGINAL_STDIN_FD): ... this new macro.
13988 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't

13998 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
14000 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N_PREPARE): Don't set ECHO_C to
14001 newline if neither \c nor -n work, as that would output two
14002 newlines. Prefer -n to \c. Reported by Stepan Kasal.
14004 2005-02-12 Stepan Kasal <kasal@ucw.cz>
14006 * lib/m4sugar/m4sh.m4 (AS_IF): Define by m4_defun, not m4_define.
14007 This causes that any required macros inside will get before the if.
14008 * doc/autoconf.texi (autom4te.cache): A typo.
14010 2005-02-12 Paul Eggert <eggert@cs.ucla.edu>
14012 Undo previous change, except keep the change to
14013 lib/autoconf/programs.m4 that replaced grep with shell
14014 pattern-matching. This is because net-snmp configure reads stdin.
14015 Reported by Noah Misch.
14017 2005-02-11 Paul Eggert <eggert@cs.ucla.edu>
14019 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin
14020 from /dev/null, as "configure" shouldn't read stdin, and this
14021 insulates us from problems (e.g., when testing for "cl").
14022 Suggested by Alexandre Duret-Lutz. Also, do this redirection
14023 before invoking "hostname" or "uname".
14024 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
14025 _AC_LINK_IFELSE): Undo previous change, as it's no longer needed.
14026 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Don't bother with
14027 "</dev/null" since it's now done at the top of 'configure'.
14028 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
14029 * lib/autoconf/programs.m4 (_AC_PATH_PROG_FLAVOR_GNU): Likewise.
14030 Also, replace grep with shell pattern-matching, to save a process.
14032 2005-02-10 Paul Eggert <eggert@cs.ucla.edu>
14034 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
14035 _AC_LINK_IFELSE): Redirect stdin to /dev/null, in an attempt to
14036 avoid thinking that Allegro Common Lisp's "cl" command is a C++
14039 2005-02-09 Paul Eggert <eggert@cs.ucla.edu>
14041 * doc/autoconf.texi (Limitations of Usual Tools): Document that
14042 grep -q isn't portable. Improve grep -s explanation.
14043 Problem reported by Dan Manthey.
14045 2005-02-08 Paul Eggert <eggert@cs.ucla.edu>
14047 * doc/autoconf.texi (Special Shell Variables): Clarify

14050 2005-02-07 Paul Eggert <eggert@cs.ucla.edu>
14052 * doc/autoconf.texi: Use @acronym for DJGPP.
14053 Fix some @code's that should have been @env's, and vice versa.
14054 Sort environment variable names.
14055 Mention that shells no longer inherit IFS.
14056 Don't recommend PATH_SEPARATOR=';' so strongly.
14057 Mention that $RANDOM might expand to the empty string.
14058 "symlink" and "soft link" -> "symbolic link".
14059 Improve mktemp description (reported by Bruno Haible).

14097 CPPFLAGS to `configure' instead of setting it in `configure'.
14099 * lib/m4sugar/m4sh.m4 (AS_UNAME): Try only /usr/bin/hostinfo, not
14100 any `hostinfo' in $PATH, since hostinfo.exe is a popular file name

14135 this fixes a bug tickled by the AT_CAPTURE_FILE change noted below.

14153 * doc/autoconf.texi (Special Shell Variables): Mention _,
14154 BIN_SH, DUALCASE. Say that variables other than "status" are safe
14155 if they contain a lower-case letter. The DUALCASE problem was
14156 reported by Ralf Wildenhues.

14166 Unicos 9 sed limitations.
14167 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Try cf77 before fort77

14198 Simplify the implementation of m4_require (a.k.a. AC_REQUIRE).
14199 Update the long comment explaining it.
14201 m4_require no longer writes an ``is required by'' line to the
14202 execution stack. It contains only one bit of non-redundant
14203 information: that the macro was required, not called. And even
14204 this bit is useless in most situations: have you ever met a macro
14205 which both calls and requires the same macro?
14207 * lib/m4sugar/m4sugar.m4 (_m4_defun_pro): Don't push a diversion...
14208 (_m4_defun_pro_outer): ... only via this macro, for the outermost

14211 (m4_expansion_stack_pop): Remove the misplaced comment.
14212 (m4_require): Don't put the ``is required by'' line to the
14213 execution stack; slightly improve the out-of-a-defun error message.
14214 (_m4_divert_grow): New macro, counter for the temporary diversions.
14215 (_m4_require_call): Use it.
14216 * tests/m4sugar.at (m4_require): Expect output without the
14217 ``is required by'' messages.

14253 2005-01-20 Paul Eggert <eggert@cs.ucla.edu>
14255 * doc/autoconf.texi (Shell Substitutions): Fix typo in case statement.
14256 Warn about newline stripping in `` and $(). Update Solaris
14258 (Limitations of Builtins): Use expr "X...", not expr "x...", as
14259 X insulates us from future changes to Posix.
14260 (Limitations of Usual Tools): For AS_DIRNAME, warn about newline
14263 2005-01-19 Stepan Kasal <kasal@ucw.cz>

14627 * lib/autoconf/functions.m4 (AC_FUNC_MEMCMP): Use
14628 "char c = '\200';" rather than "char c = 0x80;" as the

14781 Remove ansi2knr.c; nobody uses it.
14782 (ansi2knr.c-url_prefix): Remove.
14783 (cvs-update): Fix test for failure. I don't know why it ever
14786 * doc/autoconf.texi: Update URLs, some of which went stale.
14787 Use @uref rather than @href.
14789 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Have configure
14790 handle "--" as per POSIX. Suggested by Paul Pogonyshev.
14792 * config/config.guess, config/config.sub, config/elisp-comp,
14793 config/install-sh, config/mkinstalldirs, config/texinfo.tex,
14794 doc/fdl.texi, doc/standards.texi: Sync with master copy.

14803 tests/tools.at, tests/torture.at:
14804 Use "file name" rather than "filename" or "path",
14805 to be consistent with the terminology of the GNU coding standards.
14807 2004-08-19 Paul Eggert <eggert@cs.ucla.edu>
14809 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C),
14810 AC_C_LONG_DOUBLE): Undo 2004-06-04 change, as it didn't work with
14811 HP-UX 11.23 cc/aCC or Tru64 4.0 cc. Problem reported by Noah Misch in
14812 <http://lists.gnu.org/archive/html/autoconf/2004-07/msg00004.html>.
14814 More fixes to support spaces in the name of the build directory.
14815 This isn't a complete fix but it's an improvement.
14817 * bin/autoconf.as (autom4te_options): New var.
14818 Use it instead of appending to AUTOM4TE, so that we can allow
14819 spaces in the build directory's absolute name.
14820 * bin/autoheader.in ($autoconf): Allow spaces in file names.
14821 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP, _AT_CHECK,
14822 AT_CHECK_NOESCAPE): Likewise.

14834 * doc/autoconf.texi (Function Portability): Document isinf and
14835 and isnan. From a suggestion by Kevin Ryde.
14837 * lib/Autom4te/General.pm (END): Return correct exit status even
14838 if unlink succeeds and sets $?. Needed with Solaris 8's perl 5.00503.
14840 2004-08-09 Paul Eggert <eggert@cs.ucla.edu>
14842 * tests/torture.at (Deep Package): Use configure.in, not configure.ac,
14843 for compatibility with Automake 1.4. Reported by J C Fitzgerald in
14844 <http://lists.gnu.org/archive/html/bug-autoconf/2003-08/msg00051.html>.

14852 * lib/autom4te.in (Automake-preselections): Preselect
14853 AC_REQUIRE_AUX_FILE. Automake 1.10 will trace it.
14855 2004-08-02 Alexandre Duret-Lutz <adl@gnu.org>
14857 * lib/autom4te.in (Automake-preselections): Preselect
14858 AC_CANONICAL_BUILD and AC_CANONICAL_TARGET. Automake 1.9.1 will

14870 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): Use "set -o posix"
14871 with pdksh, too. Problem reported by Patrick Welche via
14873 * doc/autoconf.texi (Shellology): Note that set -o posix is
14874 useful for pkdsh, too.
14876 2004-06-24 Paul Eggert <eggert@cs.ucla.edu>
14878 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Require
14879 _AS_UNSET_PREPARE, so that we can use $as_unset directly.
14880 Don't fail if ENV or BASH_ENV is readonly.
14881 (AS_SHELL_SANITIZE): Don't fail if ENV, MAIL, MAILPATH, LC_ALL,
14882 etc. are read only. Problem reported by Ludovic Courtes.
14884 2004-06-23 Noah Misch <noah@cs.caltech.edu>
14886 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): If the shell is
14887 zsh, disable GLOB_SUBST to avoid backslash handling problems.
14890 2004-06-04 Paul Eggert <eggert@cs.ucla.edu>
14892 * doc/autoconf.texi (File System Conventions): Warn about
14893 names like "aux". Problem reported by Eric Blake.
14895 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY (C)): Use division
14896 by zero instead of array size, so that we can use any arithmetic
14897 constant expression (instead of requiring an integer constant
14898 expression). This allows us to test expressions like DBL_MAX <
14899 LDBL_MAX, which didn't conform to the C standard using the old
14901 (AC_C_LONG_DOUBLE): Put back in the tests for LDBL_MAX and LDBL_EPSILON,
14902 now that we can do floating-point tests at compile time.
14904 2004-06-02 Paul Eggert <eggert@cs.ucla.edu>
14906 * lib/autoconf/c.m4 (AC_C_LONG_DOUBLE): Don't check LDBL_MAX
14907 and LDBL_EPSILON, as the resulting expression isn't an
14908 integer constant expression and violates the C standard.
14909 Problem reported by Nelson H. F. Beebe. Also, check
14910 for "L" suffix, and check that long double doesn't have
14911 worse range or precision than double, that mixed-mode
14912 arithmetic doesn't generate a diagnostic, that double
14913 constants fit in long double.
14915 2004-06-03 Kevin Ryde <user42@zip.com.au>
14917 * doc/autoconf.texi (Function Portability): Add notes on free(NULL),
14918 malloc(0) and realloc(NULL,size).
14920 * doc/autoconf.texi (Shell Substitutions): Spelling error reported by
14923 2004-05-31 Paul Eggert <eggert@cs.ucla.edu>
14925 * lib/autoconf/headers.m4 (HAVE_STDBOOL_H): Detect _Bool bug
14926 in HP aC++/ANSI C B3910B A.05.55 [Dec 04 2003]. Problem reported
14929 2004-05-26 Paul Eggert <eggert@cs.ucla.edu>
14931 * doc/autoconf.texi (Limitations of Builtins): Mention that ! COMMAND
14932 can be rewritten using if-then-else. Suggested by Bruno Haible.
14934 2004-05-25 Paul Eggert <eggert@cs.ucla.edu>
14936 * doc/autoconf.texi (testsuite Scripts): Fix typo.
14937 Problem reported by Stepan Kasal.
14939 2004-05-24 Paul Eggert <eggert@cs.ucla.edu>
14941 * tests/Makefile.am (autoconfdir): Fix to match comment (trivial
14942 change). Patch reported by Ralf Wildenhues in
14943 <http://mail.gnu.org/archive/html/bug-autoconf/2004-05/msg00092.html>.
14945 * lib/autoconf/functions.m4 (AC_FUNC_MBRTOWC): Don't assume that a
14946 function F exists if the compiler and linker let you compile an
14947 expression like (F != 0). Recent versions of GCC optimize away
14948 the reference to F in that case, since every function address must
14949 be nonzero, so the link succeeds even if F does not exist.
14950 Problem reported by Manu in
14951 <http://mail.gnu.org/archive/html/bug-gnu-utils/2004-05/msg00060.html>.
14953 * doc/autoconf.texi (Systemology): Standardize on the spelling of
14954 "Unix". Many uses changed.
14955 (Limitations of Builtins): Explain better why the ! command isn't
14958 2004-05-22 Alexandre Duret-Lutz <adl@gnu.org>
14960 * lib/autom4te.in (Automake-preselections): Preselect
14961 LT_SUPPORTED_TAG in lieu of AC_LIBTOOL_TAGS.

14965 * doc/autoconf.texi (Function Portability): Add strerror_r, cross
14966 referencing AC_FUNC_STRERROR_R.
14968 * doc/autoconf.texi (Particular Functions): In AC_FUNC_CLOSEDIR_VOID,
14969 note pessimistic assumption when cross compiling.
14971 2004-05-16 Paul Eggert <eggert@cs.ucla.edu>
14973 * doc/autoconf.texi (Limitations of Make): Note that BSD make
14974 (until 2004) invoked subcommands with sh -e, contra POSIX.
14975 Reported by Kevin Ryde.
14977 2004-05-10 Eric Sunshine <sunshine@sunshineco.com>
14979 * programs.m4 (_AC_PROG_GREP): Fixed bug where PATH argument handed to
14980 _AC_PATH_PROG_FEATURE_CHECK contained leading whitespace (i.e.
14981 " $PATH:/usr/xpg4/bin"). This resulted in bogus tests, such as
14982 `test -f " /usr/bin/grep"', which _always_ failed.
14983 (AC_PROG_SED): Ditto bogus PATH fix.
14984 * autoconf.texi (AC_PROG_GREP): Properly document that this macro
14985 requires that grep correctly supports _multiple_ `-e' options, rather
14986 than stating only that grep should accept `-e'.
14988 2004-05-03 Paul Eggert <eggert@cs.ucla.edu>
14990 Port to C99, which requires that 'exit' be declared.
14992 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Use AC_INCLUDES_DEFAULT
14993 to ensure that stdlib.h is included.
14994 * lib/autoconf/functions.m4 (_AC_LIBOBJ_ALLOCA, AC_FUNC_SETPGRP,
14995 AC_FUNC_STRTOD, AC_FUNC_SETVBUF_REVERSED, AC_FUNC_FORK, _AC_FUNC_FORK,
14996 _AC_FUNC_VFORK, AC_FUNC_WAIT3): Likewise.
14997 * lib/autoconf/specific.m4 (AC_SYS_RESTARTABLE_SYSCALLS): Likewise.
14998 * lib/autoconf/types.m4 (AC_TYPE_GETGROUPS): Likewise.
14999 * lib/autoconf/headers.m4 (AC_HEADER_STDC): Include <stdlib.h>
15000 when using 'exit' in a test; C99 requires that 'exit' be declared.
15002 2004-05-02 Paul Eggert <eggert@cs.ucla.edu>
15004 * doc/autoconf.texi (Particular Programs): AC_PROG_GREP
15005 now prefers 'grep' implementations that accept -e.
15006 (Limitations of Usual Tools): Describe problems of traditional
15007 egrep and fgrep with long input lines, and of traditional grep
15009 * lib/autoconf/programs.m4 (AC_PROG_GREP): Check for -e, too.
15010 (_AC_PROG_GREP): Assume 3rd arg is properly quoted for the shell.
15011 All callers changed. Append /usr/xpg4/bin to the PATH, for
15013 (_AC_FEATURE_CHECK_LENGTH): Discard stderr, so we don't bother
15014 the user with complaints about multiple -e options.
15015 * tests/local.at (AC_STATE_SAVE): Use $GREP, not grep.
15016 Define it with AC_PROG_GREP.
15017 * configure.ac (AC_PROG_GREP): Add.
15018 * lib/freeze.mk (GREP): New macro.
15020 2004-05-02 Eric Sunshine <sunshine@sunshineco.com>
15022 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Consult $SHELL as
15023 a possible candidate only after all others fail, rather than
15024 consulting it first. This improves backward compatibility by
15025 better reflecting the way shell selection occurred in previous
15026 versions of Autoconf, and should help to avoid triggering latent
15027 problems in other packages, such as the one in Automake where zsh
15028 is not handled robustly:
15029 http://mail.gnu.org/archive/html/automake/2004-04/msg00095.html
15030 Although it is not Autoconf's responsibility to work around
15031 problems in Automake, it nevertheless makes sense to avoid
15032 introducing unnecessary incompatibilites.
15034 2004-04-22 Albert Chin-A-Young <china@thewrittenword.com>,
15035 Gary V. Vaughan <gary@gnu.org>
15037 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Don't guess
15038 how deeply nested we are when a suitable tool is found, set the
15039 ac_path_TOOL_found flag.
15040 (_AC_PATH_PROG_FEATURE_CHECK): Encapsulate knowledge of how deeply
15041 nested we are in this macro. Break out of all 3 nested loops if
15042 ac_path_TOOL_found is set.
15044 2004-04-21 Gary V. Vaughan <gary@gnu.org>
15046 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Break out
15047 of the _AS_PATH_WALK loop too if GNU flavor is found.
15049 2004-04-21 Alexandre Duret-Lutz <adl@gnu.org>
15051 * doc/autoconf.texi (Limitations of Make): Update documentation
15052 for `$<'. New entry `Long lines', based on a report from Simon
15053 Josefsson. Augment the documentation for SHELL = @SHELL@ with a
15054 paragraph about DJGPP, based on a mail from Richard Dawe.
15056 2004-04-20 Paul Eggert <eggert@twinsun.com>
15058 * tests/c.at (C keywords): Don't assume that GCC supports
15059 "restrict" and "inline", as sufficiently-old GCC versions do not
15060 (also, GCC configured to be in pedantic C89 mode does not).
15061 Problem reported by Sumit Pandya in:
15062 http://mail.gnu.org/archive/html/autoconf/2004-04/msg00092.html
15064 * lib/autoconf/c.m4 (_AC_PROG_CC_G, _AC_PROG_CXX_G): Don't
15065 consider -g to work if it generates warnings when plain compiles
15066 don't. Problem reported by Braden McDaniel in:
15067 http://mail.gnu.org/archive/html/autoconf-patches/2003-07/msg00014.html
15069 * doc/autoconf.texi (Slashes): New section, to document a problem
15070 reported by Jim Meyering in:
15071 http://mail.gnu.org/archive/html/bug-coreutils/2004-02/msg00060.html
15073 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Remove potential
15074 linker output files before linking, to work around IRIX 6 linker bug.
15075 Problem reported by Rainer Orth in:
15076 http://mail.gnu.org/archive/html/autoconf-patches/2004-02/msg00007.html
15078 2004-04-20 Gary V. Vaughan <gary@gnu.org>
15080 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Make the
15081 best tool so far counter rely on the tool path variable name to
15082 avoid checks for one tool being affected by the results of running
15083 the length check on a previous tool.
15085 * lib/autoconf/programs.m4 (_AC_PROG_GREP): Take an additional
15086 match expression argument, as different greps have different
15087 regular expression flavours.
15088 (AC_PROG_FGREP): Pass 'FGREP'. fgrep treats all match chars as
15090 (AC_PROG_EGREP): Pass 'EGREP$'.
15091 (AC_PROG_GREP): Pass 'GREP$'.
15093 2004-04-20 Albert Chin-A-Young <china@thewrittenword.com>
15095 * lib/autoconf/programs.m4 (AC_PROG_GREP): Cache variable
15096 is `ac_cv_path_GREP', not `oc_cv_path_GREP'.
15098 2004-03-29 Paul Eggert <eggert@twinsun.com>
15100 * doc/autoconf.texi (Particular Headers, Particular Types, Generic
15101 Types, Specific Compiler Characteristics, System Services,
15102 Obsolete Macros): Use 'long int', 'short int', 'unsigned int'
15103 etc. consistently instead of 'long', 'short', 'unsigned' etc.
15104 * lib/autoconf/c.m4 (AC_LANG_INT_SAVE(C), AC_C_BIGENDIAN): Likewise.

15118 * doc/autoconf.texi (Particular Structures): AC_STRUCT_TIMEZONE
15119 now defines HAVE_DECL_TZNAME if it is declared, when
15120 HAVE_STRUCT_TM_TM_ZONE is not defined.
15121 * lib/autoconf/types.m4 (AC_STRUCT_TIMEZONE): Implement this.
15122 Do not assume atoi. Rely on HAVE_DECL_TZNAME when testing
15125 2004-03-28 Steven G. Johnson <stevenj@fftw.org>
15127 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Corrected
15128 superfluous backslashing of quotes (") in sed expressions;
15129 thanks to Paul Eggert.
15131 2004-03-26 Steven G. Johnson <stevenj@alum.mit.edu>
15133 * lib/autoconf/fortran.m4 (_AC_PROG_FC): new name of Intel
15134 Fortran compiler is ifort, also added pghpf; thanks to Nelson
15135 H. F. Beebe for the bug report.
15137 2004-03-26 Steven G. Johnson <stevenj@fftw.org>

15197 2004-02-23 Gary V. Vaughan <gary@gnu.org>
15199 * bin/autoreconf.in (autoreconf_current_directory): Recognize LT_INIT
15200 from the next generation of Libtool.
15201 * lib/autom4te.in (Autoreconf-preselections): Ditto.
15203 2004-02-20 Alexandre Duret-Lutz <adl@gnu.org>
15205 * doc/autoconf.texi (Limitations of Usual Tools) <mkdir>: `mkdir -p'
15206 is not always thread-safe. Report from Nathanael Nerode.
15208 2004-02-18 Paul Eggert <eggert@twinsun.com>
15210 Fix a dependencies problem, stemming from a Autoconf 2.59 build
15211 problem on QNX reported by Stephen Rasku in
15212 <http://mail.gnu.org/archive/html/bug-autoconf/2004-02/msg00066.html>.
15214 * bin/Makefile.am ($(srcdir)/autoconf.in): Depend on
15215 $(m4sh_m4f_dependencies); this removes a FIXME.
15216 * tests/Makefile.am ($(srcdir)/wrapper.in): Likewise.
15217 (MAINTAINERCLEANFILES): Split into pieces,
15218 one per related section. Add $(srcdir)/wrapper.in.
15220 2004-02-09 Paul Eggert <eggert@twinsun.com>
15222 * doc/autoconf.texi (Setting Output Variables): Emphasize that
15223 AC_SUBST provides no portable way to escape literal newlines.
15225 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS): Ignore all
15226 flags of the form -lcrt*.o, not just -lcrt[01].o and -lcrtbegin.o.
15227 Darwin uses -lcrt2.o and there's little point to cataloging all
15228 the system variants. Partial fix reported by Andreas Waechter in:
15229 http://mail.gnu.org/archive/html/autoconf-patches/2004-02/msg00006.html

15235 * doc/autoconf.texi (AU_DEFUN): Fix English,
15236 suggested by Paul Eggert.
15237 * lib/autoconf/autoupdate.m4: Correct reference to
15238 acobsolete.m4, suggested by Alexandre Duret-Lutz.
15240 2004-02-02 Paolo Bonzini <bonzini@gnu.org>
15242 * bin/autoupdate.in: Define __file__ so that warnings
15243 refer to the correct file.
15244 * doc/autoconf.texi (AU_DEFUN): Describe more correctly
15245 the behavior of the third argument.
15246 * lib/autoconf/autoupdate.m4 (AU_DEFUN): Describe more
15247 correctly the behavior of the third argument. Document
15248 what the three macros that AU_DEFUN defines do. Fix
15249 warning message when the third argument includes $0
15250 (reported by Alexandre Duret-Lutz).
15252 2004-01-30 Paolo Bonzini <bonzini@gnu.org>
15253 Eric Sunshine <sunshine@sunshineco.com>
15254 Paul Eggert <eggert@twinsun.com>
15256 * lib/m4sugar/m4sh.m4 (M4SH-SANITIZE): New diversion.
15257 (AS_INIT): Output shell initialization there. Removed optional
15258 parameter. Expand _AS_SHELL_FN_SPY.
15259 (AS_INIT_WITH_SHELL_FN): Removed.
15260 (_AS_SHELL_FN_SPY): New macro.
15261 (AS_DETECT_REQUIRED, AS_DETECT_SUGGESTED): New
15263 (AS_SHELL_SANITIZE): Remove loop to find better shell
15264 and documentation for the parameter.
15265 (_AS_DETECT_BETTER_SHELL): Move it here.
15266 (_AS_SHELL_FN_WORK): Remove shell invocation, reformat.
15267 (_AS_RUN): Move it here, support testing with eval.
15268 (AS_REQUIRE_SHELL_FN): Require shell functions when
15270 (_AS_LINENO_WORKS): Put around braces, we do not
15271 trigger the bash bug anymore.
15272 * lib/autotest/general.m4: Document M4SH-SANITIZE, do not
15273 use AS_INIT_WITH_SHELL_FN.
15274 * bin/autoconf.in, tests/wrapper.in: Regenerated.
15276 2004-01-30 Paolo Bonzini <bonzini@gnu.org>
15278 * bin/autoupdate.in: Trace AU_DEFINE instead of AU_DEFUN.
15279 * doc/autoconf.texi: Don't say that the third parameter
15281 * lib/autoconf/autoupdate.m4 (AU_DEFINE): New dummy macro.
15282 (AU_DEFUN): Honor the third parameter, create autoupdate
15283 macros with AU_DEFINE.
15284 * lib/autoconf/headers.m4 (AC_USG, AC_MEMORY_H,
15285 AC_DIR_HEADER): Use AU_DEFUN's third parameter.
15286 * lib/autoconf/lang.m4 (AC_LANG_SAVE): Likewise.
15287 * lib/autoconf/programs.m4 (AC_RSH): Likewise.
15288 * lib/autoconf/specific.m4 (AC_HAVE_POUNDBANG,
15289 AC_ARG_ARRAY, AC_CYGWIN, AC_EMXOS2, AC_MINGW32,

15291 * lib/autoconf/types.m4 (AC_INT_16_BITS, AC_LONG_64_BITS,
15292 AC_STRUCT_ST_BLKSIZE, AC_STRUCT_ST_RDEV): Likewise.
15293 * lib/autoconf/status.m4: Remove FIXME.
15294 * tests/local.at (AT_CHECK_AU_MACRO): Ignore stderr, check
15295 that the macro is not present anymore in the updated
15297 * tests/tools.at (autoupdate AC_LINK_FILES): Ignore stderr
15300 2004-01-28 Paul Eggert <eggert@twinsun.com>
15302 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Add 2004 to
15304 * lib/autoconf/general.m4 (_AC_INIT_COPYRIGHT): Add 1992 thorugh
15305 2003 (except 1997) to the list of copyright years. This undoes
15306 the 2003-05-22 change, which removed the older years from the list.
15307 * lib/autoconf/status.m4 (AC_OUTPUT): Update copyright date to 2004.
15309 2004-01-27 Gary V. Vaughan <gary@gnu.org>
15310 Albert Chin-A-Young <china@thewrittenword.com>
15312 * lib/autoconf/programs.m4 (AC_PROG_GREP): New macro to test for a
15313 grep or ggrep program in PATH that accepts as long lines as
15315 * lib/autoconf/programs.m4 (_AC_PROG_GREP): Factor out the core of
15317 (AC_PROG_EGREP, AC_PROG_FGREP): Use it to find best available
15318 egrep and fgrep respectively if $GREP -E/-F don't work.
15319 (_AC_PATH_PROG_FEATURE_CHECK): Factor out the common core of
15320 _AC_PROG_GREP, and AC_PROG_SED.
15321 (_AC_FEATURE_CHECK_LENGTH): New helper macro for finding the
15322 longest input length accepted by a command.
15323 (AC_PROG_SED): Use it.
15324 * doc/autoconf.texi (Particular Programs): Document the changes.
15327 2004-01-27 Paul Eggert <eggert@twinsun.com>
15329 * bin/autoconf.as ($version): Update copyright from 2003 to 2004.
15330 * bin/autoheader.in, bin/autom4te.in, bin/autoreconf.in,
15331 bin/autoscan.in, bin/autoupdate.in, bin/ifnames.in: Likewise.
15332 * lib/autoconf/general.m4 (_AC_INIT_COPYRIGHT): Likewise.
15334 * Makefile.in, aclocal.m4, configure, bin/Makefile.in,
15335 bin/autoconf.in, config/Makefile.in, config/config.guess,
15336 config/config.sub, config/install-sh, config/mdate-sh,

15348 tests/actypes.at: Regenerate and/or sync with original
15351 2004-01-26 Paul Eggert <eggert@twinsun.com>
15353 * doc/autoconf.texi (Default Includes): Include <stdint.h> even if
15354 HAVE_INTTYPES_H is defined. This is needed on Tru64 5.1b with
15355 Compac C V6.5-207 (dtk), which defines uintmax_t in <stdint.h> but
15356 not <inttypes.h>. Problem reported by Tim Mooney in
15357 <http://mail.gnu.org/archive/html/bug-coreutils/2004-01/msg00147.html>.
15358 * lib/autoconf/headers.m4 (_AC_INCLUDES_DEFAULT_REQUIREMENTS):
15361 * lib/autoconf/programs.m4 (AC_PROG_SED): Use diff, not sed;
15362 otherwise "make check" fails because it forbids cmp (I guess
15363 because cmp treats files as binary on DOS-like systems).
15365 * tests/mktests.sh: Update copyright date to 2004, since some tests
15366 have changed in 2004.
15368 2004-01-23 Gary V. Vaughan <gary@gnu.org>
15370 * lib/autoconf/programs.m4 (AC_PROG_SED): New macro to test for a
15371 non-truncating sed or gsed program in PATH.
15372 * tests/acprograms.at: Add it.
15373 * doc/autoconf.texi (Particular Programs): Document it.
15376 2004-01-15 Paul Eggert <eggert@twinsun.com>
15378 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Try -std, not -std1, since
15379 -std1 disables some useful extensions on Tru64. Problem reported
15380 by N. Lichtmaier in
15381 <http://mail.gnu.org/archive/html/autoconf/2004-01/msg00100.html>.
15383 2004-01-14 Paul Eggert <eggert@twinsun.com>
15385 * doc/autoconf.texi (Programming in M4sh): Document that
15386 AS_MKDIR_P succeeds if the destination is a symbolic link
15387 to an existing directory.
15388 (Limitations of Usual Tools): Note that mkdir -p might not
15389 succeed on symlinks to directories.
15391 2004-01-13 Paul Hilfinger <hilfinger@CS.Berkeley.EDU>
15393 * lib/autoconf/autoupdate.m4 (AU_DEFUN): Grammar fix in comment.
15394 * bin/autoheader.in: Grammar fix in message.
15395 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P):
15396 Test for dir before calling mkdir -p. (trivial changes)
15398 2004-01-13 Eric Blake <ebb9@byu.net>
15400 * doc/autoconf.texi (Obsolete Macros): In AC_TRY_COMPILE and
15401 AC_TRY_LINK, s/AC_LANG_SOURCE/AC_LANG_PROGRAM/. (trivial change)
15403 2004-01-10 Jim Meyering <jim@meyering.net>
15405 * doc/autoconf.texi (Running the Preprocessor): Correct grammar.
15407 2004-01-09 Paul Eggert <eggert@twinsun.com>
15409 * lib/autoconf/general.m4: Fix bug: AC_CHECK_SIZEOF evokes a warning
15410 with `autoconf -Wall,error'. Bug reported by Eric Blake in:
15411 http://mail.gnu.org/archive/html/autoconf-patches/2004-01/msg00000.html
15412 (_AC_COMPUTE_INT_COMPILE): Invoke _AC_COMPILE_IFELSE, not
15413 AC_COMPILE_IFELSE, since we now assume our caller invokes
15414 AC_LANG_COMPILER_REQUIRE, for symmetry with _AC_COMPUTE_INT_RUN.
15415 (_AC_COMPUTE_INT_RUN): Likewise, for _AC_RUN_IFELSE instead
15416 of AC_RUN_IFELSE; this avoids the warning mentioned above.
15417 (_AC_COMPUTE_INT): Invoke AC_LANG_COMPILER_REQUIRE.
15419 2004-01-07 Paul Eggert <eggert@twinsun.com>
15421 * lib/autoconf/general.m4 (_AC_LIBOBJS_NORMALIZE): Avoid \$ inside
15422 `"'...'"`, as it's confusing (and I suspect it may not work on
15423 some platforms). The code was incorrect anyway, as it assumed
15424 that \$ evaluated to itself in that context. Reported by
15425 Alexandre Duret-Lutz.
15427 2004-01-07 Alexandre Duret-Lutz <adl@gnu.org>
15429 * lib/autom4te.in (Automake-preselections): Preselect AC_LIBTOOL_TAGS
15430 and _LT_AC_TAGCONFIG.
15432 2004-01-06 Paul Eggert <eggert@twinsun.com>
15434 * doc/autoconf.texi (One Macro Call): Fix an incorrect
15435 example, and add more examples. Reported by Eric Sunshine.
15437 2004-01-05 Paul Eggert <eggert@twinsun.com>
15439 * doc/autoconf.texi (Limitations of Usual Tools):
15440 Remove warning against "rm -fr" introduced yesterday; it
15443 * bin/Makefile.am (autoconf, autoheader, autom4te, autoreconf,
15444 autoscan, autoupdate, ifnames): Don't use chmod -w.
15445 * lib/Makefile.am (autom4te.cfg): Likewise.
15446 * doc/autoconf.texi (Limitations of Usual Tools): Warn against
15449 2004-01-04 Paul Eggert <eggert@twinsun.com>
15450 Paolo Bonzini <bonzini@gnu.org>
15452 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Speed up sed scripts
15453 by doing lineno substitution only on lines containing "$LINENO".
15455 2004-01-04 Paul Eggert <eggert@twinsun.com>
15457 * lib/autoconf/general.m4 (AC_ARG_PROGRAM):
15458 Use "rm -f" to remove conftest.sed, not plain "rm".
15459 Bug reported by David Relson in
15460 <http://mail.gnu.org/archive/html/autoconf/2004-01/msg00011.html>.
15462 * Makefile.am (autom4te-update):
15463 Replace "rm -rf" and "rm -fr" with "rm -f -r", as POSIX requires.
15464 * Makefile.maint (my-distcheck, do-po-update): Likewise.
15465 * doc/autoconf.texi (Guidelines): Likewise.
15466 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Likewise.

15472 * tests/tortue.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS,
15474 * doc/autoconf.texi (Limitations of Usual Tools):
15475 Warn against "rm -fr".
15477 2004-01-03 Paul Eggert <eggert@twinsun.com>
15479 * doc/autoconf.texi (Limitations of Usual Tools): Mention that cc
15480 -c -o might not work. From a suggestion by Kevin Ryde.
15481 (C Compiler, Generating Sources, Limitations
15482 of Usual Tools, Limitations of Make, Making testsuite Scripts):
15483 Don't put '-o' after non-options, as POSIX doesn't allow this.
15484 Mention that cc's name might be gcc or c89 or whatever.
15486 2004-01-04 Kevin Ryde <user42@zip.com.au>
15488 * doc/autoconf.texi: Add various further index entries.
15490 2003-12-29 Paul Eggert <eggert@twinsun.com>
15492 * bin/autoreconf.in (autoreconf_current_directory):
15493 Fix typo: mkdir without umask arg.
15495 2003-12-27 Alexandre Duret-Lutz <adl@gnu.org>
15497 * doc/autoconf.texi (Limitations of Make) <Automatic rule rewriting>:
15498 Documents OSF1/Tru64 make behavior. Replace `VPATH = ../src' by
15499 `VPATH = ../pkg/src' in examples to make the OSF1/Tru64 make
15500 explanation clearer.
15502 2003-12-24 Andreas Schwab <schwab@suse.de>
15504 * doc/autoconf.texi (Default Includes): Fix misspelling of

15510 * configure: Regenerate.
15511 * tests/atlocal.in: Store the result here.
15512 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Extracted from
15513 tools.at, looking in atlocal's ac_cv_sh_n_works instead
15514 of explicitly testing.
15515 (AT_CHECK_PERL_SYNTAX): Moved from tools.at.
15516 (AT_CHECK_AUTOCONF): Test for the configure script syntax.
15517 * tests/tools.at (Syntax of the shell scripts): Simplify
15518 using AT_CHECK_SHELL_SYNTAX.

15520 AT_CHECK_PERL_SYNTAX.

15532 Extracted from AS_SHELL_SANITIZE.
15533 (_AS_SHELL_FN_WORK, AS_INIT_WITH_SHELL_FN): New
15535 (AS_SHELL_SANITIZE): Move reinvocation code from
15536 _AS_LINENO_WORKS, use it to find out if shell
15538 (_AS_LINENO_WORKS): Don't find another shell if $LINENO
15540 (AS_INIT): Pass parameter down to AS_SHELL_SANITIZE.

15587 parameter of AU_DEFUN.
15588 * lib/autoconf/autoupdate.m4 (AU_DEFINE): Remove.
15589 (AU_DEFUN): Remove the third parameter, it was not used.
15590 Use AC_DEFUN directly, not AU_DEFINE.
15591 * lib/autoconf/status.m4 (AC_LINK_FILES): Move the message into
15592 the expanded body, consistently with other macros such as AC_USG.
15594 2003-11-17 Paul Eggert <eggert@twinsun.com>
15596 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Put at least 14 bytes
15597 into the initial confdefs.h, to work around a bug in NextStep 3.3
15598 patch 3 reported by Eric Sunshine.
15600 2003-11-15 Kevin Ryde <user42@zip.com.au>
15602 * doc/autoconf.texi (Using System Type): Revise, showing $host rather
15603 than $target since the latter is not usual, add guidelines on when to
15604 use or not use the system type.

15608 * doc/autoconf.texi (Limitations of Usual Tools): Fix what looks like a

15785 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Omit quoted

15811 cache variable instead of $G77 to decide whether to include -O2,
15812 since $G77 is specific to Fortran 77.

15816 * lib/autoconf/fortran.m4 (AC_FC_FREEFORM): Support Absoft "-f
15817 free" flag. Re-order flags tested into rough order of popularity.
15819 2003-10-03 Steven G. Johnson <stevenj@alum.mit.edu>
15821 * lib/autoconf/fortran.m4 (AC_PROG_FC): Reverse the order of the
15822 arguments so that it can be used with syntax identical to
15823 AC_PROG_F77, and so that we can more easily decide to
15824 remove/deprecate the DIALECT optional argument in the future if it
15825 proves troublesome.
15826 (AC_FC_FREEFORM): Exit 77 upon failure to fix test suite for

15891 <http://mail.gnu.org/archive/html/autoconf/2003-07/msg00042.html>.
15892 (_AS_MKDIR_P_PREPARE): Change "rm -fr ./-p" to the more-conservative
15893 "test -d ./-p && rmdir ./-p". Suggested by Andreas Schwab in:

15898 * lib/autoconf/status.m4 (_AC_OUTPUT_COMMANDS): Make sure the
15899 directory for AC_CONFIG_COMMANDS' first argument exists.
15900 This makes valid the invocation of _AC_SRCPATH that follows.

15925 The test suite are sometimes assigning timings incorrectly.
15926 Reported by Henk Krus.
15927 Diagnosed by Nicolas Joly.
15929 * lib/autotest/general.m4 (AT_CLEANUP): Rename AT_help as
15931 Instead of making AT_help a sequence of assignments to grow
15932 $at_help_all, just make AT_help_all be the growing contents of
15933 $at_help_all, and make a single assignment in...
15935 (at_times_skip): Flip the meaning and rename as...

15947 (ifnames): chmod -w.
15948 * tests/wrapper.as (AUTOCONF, AUTOM4TE, ): Point to tests/
15949 executables, not bin/ executables! Otherwise all the magic needed
15950 to find non installed files is turned off. This caused a failure
15951 of test 40 and 41 that ran aclocal 1.8 which in turn ran autom4te
15952 as found in its environment (sent by tests/autoreconf): pointing
15953 to bin/autom4te that could not find its files.
15954 * tests/mktests.sh: Force the replacement of generated files, for
15955 the sake of "mv" program that are interactive when overwriting a

16050 2003-09-02 Steven G. Johnson <stevenj@alum.mit.edu>
16052 Add support for newer Fortran dialects. The F77 interface is
16053 unchanged, and continues to support Fortran 77. New FC macros
16054 correspond to all the old F77 macros, with output variables FC,
16055 FCFLAGS, and FCLIBS. AC_PROG_FC defaults to picking the newest
16056 available dialect, but older dialects can be specified. There are
16057 new macros AC_FC_SRCEXT to set the source extension, and
16058 AC_FC_FREEFORM to accept free-form source files.
16060 * lib/autoconf/c.m4 (_AC_LANG_PREFIX(C), _AC_LANG_PREFIX(C++)):

16146 (local-check): New.
16148 * Makefile.am (EXTRA_DIST): Add Makefile.cfg.
16149 * configure.ac: Require Automake 1.7.6.
16151 2003-08-22 Akim Demaille <akim@epita.fr>
16153 Output stack traces in warnings.
16155 * lib/m4sugar/m4sugar.m4 (_m4_warn): New.
16156 Replace the former...
16157 (m4_warn): Pass the call stack to _m4_warn.
16158 * bin/autom4te.in: Adjust to output the call stack.
16159 * tests/m4sugar.at (m4@&t@_warn): Adjust.
16161 2003-08-22 Akim Demaille <akim@epita.fr>
16163 * lib/Autom4te/Request.pm, lib/Autom4te/C4che.pm: New.
16164 * bin/autom4te.in: Adjust.
16166 2003-08-21 Akim Demaille <akim@epita.fr>
16168 * lib/Autom4te/General.pm (&file_name_is_absolute): Remove.
16169 (&verbose): Remove.
16170 (&getopt): Adjust the note and verb channels, depending upon
16172 * bin/autoheader.in, bin/autom4te.in, bin/autoscan.in,
16173 * bin/autoupdate.in: Adjust.
16174 Use &verb, not &verbose.
16176 2003-08-21 Akim Demaille <akim@epita.fr>
16178 * bin/autoheader.in (&parse_args): Use &parse_warnings and
16180 ($help): Use Autom4te::ChannelDefs::usage.
16181 * bin/autoscan.in: Use Autom4te::ChannelDefs.
16182 * lib/Autom4te/General.pm: Don't export error: you don't own it.
16184 2003-08-21 Akim Demaille <akim@epita.fr>
16186 First stab at preserving warnings between calls to autom4te,
16187 including when the cache is used.
16189 There are still several issues: (i) there are too many runs of m4
16190 (one for include, one for warnings, and some more), (ii) warnings
16191 spreading on several lines are not handled gracefully, (iii) the
16192 code meant to have the call stack display for errors does not work
16193 (its handling should move from m4 to autom4te).
16195 * bin/autom4te.in Autom4te::Channels, Autom4te::ChannelDefs):
16197 (@preselect): Add m4_warn.
16198 ($exit_status): Remove, use $exit_code.
16199 ($help): Use Autom4te::ChannelDefs::usage.
16200 (&handle_m4): No longer define the m4_warnings.
16201 At each run, extract and report the warnings.
16202 Always cache the result, including if the exit status is on
16203 failure, since if nothing changes, we should result in the same
16204 failure, hence we can use the cache.
16205 * lib/m4sugar/m4sugar.m4 (m4_warning_ifelse, _m4_warning_ifelse)
16206 (_m4_warning_error_ifelse, __m4_warning_error_ifelse, _m4_warn):
16208 (m4_warn): Redefine as a do-nothing: it is its invocation that
16209 matters, as warnings are now reported via traces.
16210 * lib/autoconf/general.m4 (AC_DIAGNOSE): Don't make it a copy of
16211 the contents of m4_warn: make it _call_ m4_warn, so that tracing
16212 the latter reveals calls to the former.
16216 * tests/m4sugar.at (m4@&t@_warn): Use existing warning categories.
16218 2003-08-21 Akim Demaille <akim@epita.fr>

16229 (&usage): Return a string, not a side effect.
16230 (cross): New warning category.
16232 2003-08-21 Akim Demaille <akim@epita.fr>
16234 * lib/Autom4te/Configure_ac.pm (&find_configure_ac)
16235 (&require_configure_ac): Accept an optional directory argument.
16236 ($configure_ac): Remove.
16237 * lib/Autom4te/General.pm (&find_configure_ac, &canonfile)
16238 (&catfile): Remove.
16239 * bin/autoheader.in, bin/autoreconf.in, bin/autoupdate.in,
16240 * bin/autoscan.in: Adjust.
16242 2003-08-20 Akim Demaille <akim@epita.fr>
16244 * bin/autoheader.in: Remove duplicate 'use Autom4te::FileUtils'.
16245 Reported by Alexandre Duret-Lutz.
16247 2003-08-20 Akim Demaille <akim@epita.fr>
16249 * bin/autoupdate.in, bin/autoheader.in, bin/autoreconf.in,
16250 * bin/autom4te: Adjust.
16251 In particular, be Autoconf tools are really silent when properly
16252 working, bind the verbosity of the 'note' channel to $verbose.
16253 * lib/Autom4te/General.pm (&find_file, &mtime, &update_file)
16254 (&xsystem, &contents): Remove, since they are exported by...
16255 * lib/Autom4te/FileUtils.pm: this.
16257 * lib/Autom4te/General.pm (&up_to_date_p): Move to...
16258 * lib/Autom4te/FileUtils.pm: here.
16260 2003-08-20 Akim Demaille <akim@epita.fr>
16262 * lib/Autom4te/Channels.pm, lib/Autom4te/ChannelDefs.pm

16316 DESCRIPTION rather than FILE and LINE. Shorten result to fit in new,
16317 shorter column three. Add DESCRIPTION to log file content.
16319 2003-08-13 Derek Price <derek@ximbiot.com>
16321 * lib/autotest/general.m4 (AT_INIT): Correct typo in final status
16324 2003-08-12 Derek Price <derek@ximbiot.com>
16326 * lib/autotest/general.m4 (AT_CHECK): Use new _AT_CHECK API.

16328 (_AT_CHECK): ...this new macro.
16330 2003-08-07 Derek Price <derek@ximbiot.com>
16332 * lib/autotest/general.m4 (AT_CHECK): Move core functionality...

16354 * lib/autoconf/functions.m4 (AC_FUNC_MMAP): Cast pointer to

16373 From Gareth McCaughan.
16375 2003-06-23 Akim Demaille <akim@epita.fr>
16377 * lib/autotest/general.m4 (AT_INIT): Report a single config.log,
16378 not all of them. This fixes 1. the fact that when testing
16379 Autoconf there are many many config.log, 2. the incorrect use of
16380 top_srcdir to find config.log.
16381 Don't mix the detailed output of failed test with the summary of
16382 failures. Rather, append detailed log afterwards.
16384 2003-06-23 Akim Demaille <akim@epita.fr>
16386 * tests/local.at (AT_CHECK_CONFIGURE): Adjust to the verbose being
16387 always run: output config.log on $at_group_log.
16389 2003-06-23 Akim Demaille <akim@epita.fr>
16391 * tests/torture.at (#define header templates): Don't use quotes in

16408 error from OSF 4.0 Compaq cc in its default almost-ANSI mode, thereby
16409 ensuring we add -std1 for full-ANSI.
16411 * doc/autoconf.texi (hdrindex): New macro.

16442 (TEST_SCRIPT): New diversion.
16443 (AT_SETUP): Divert output to TEST_SCRIPT and move some code...
16444 (AT_CLEANUP): ...to here. Undivert TEST_SCRIPT.
16445 (AT_INIT): Support for expected failures.

16460 is the inverse of localtime.
16462 2003-05-25 Alexandre Duret-Lutz <adl@gnu.org>
16464 * lib/Autom4te/General.pm (END): Print diagnostics to STDERR.
16465 (handle_exec_errors): New function. Work around $! being
16466 altered by WEXITSTATUS.
16467 (xqx, xsystem): Use handle_exec_errors.
16469 2003-05-23 Alexandre Duret-Lutz <adl@gnu.org>
16471 * lib/Autom4te/General.pm (END): Rewrite exit code processing.
16472 Do not call `_exit()', simply modify `$?'.
16473 (xsystem): Reset $! before running system, and check it afterward.
16474 * tests/tools.at (autoupdating AC_PREREQ): Expect exit status
16475 63 for version mismatches.
16477 2003-05-23 Akim Demaille <akim@epita.fr>
16479 * lib/autoconf/status.m4: Prefer "TAB-SP" to "SP-TAB", because of
16480 Emacs' dangerous whitespace.el behavior (smashing "useless" spaces in
16481 the middle of a line).
16482 * lib/m4sugar/m4sugar.m4: Likewise.

16485 2003-05-23 Akim Demaille <akim@epita.fr>
16487 * lib/m4sugar/m4sugar.m4 (m4_version_prereq): Failure causes an

16489 difference with a plain failure.

16499 Paul Eggert <eggert@twinsun.com>
16501 * lib/autoconf/c.m4 (_AC_PROG_CXX_EXIT_DECLARATION):
16502 Remove `#include <stdlib.h>' from the list; we should never
16503 make confdefs.h include <stdlib.h> or <cstdlib>, because the
16504 resulting namespace pollution would cause other tests to fail.
16505 Configure scripts run with some older versions of g++ and HP's
16506 aCC would fail due to such an #include. Problems reported by
16507 Matthew Mueller in <http://bugs.debian.org/120704> and by
16509 <http://mail.gnu.org/archive/html/autoconf/2003-05/msg00063.html>.
16510 In the test, use the test declaration before including <stdlib.h>,
16511 as that's closer to how it'll be used.
16513 2003-05-23 Akim Demaille <akim@epita.fr>
16515 * doc/autoconf.texi (Header Portability): ucred.h.
16518 2003-05-22 Paolo Bonzini <bonzini@gnu.org>
16520 Overhaul Autotest's logging: generate separate log files
16521 in testsuite.dir/NNN/testsuite.log, and append them to
16522 testsuite.log instead of re-running the test verbosely.
16524 * lib/autotest/general.m4 (AT_INIT): Use a single redirected
16525 file descriptor, write 0 to at_status_file instead of setting
16526 at_status=0, initialize some new variables (at_status_file,
16527 at_group_log, at_suite_log, at_tee_pipe). Remove the cruft
16528 to rerun the tests, instead append the at_group_log to the
16529 at_suite_log when a test fails.
16530 (AT_SETUP): pipe the test case's output into at_tee_pipe,
16531 with the AS_MESSAGE_LOG_FD redirected to stdout.
16532 (AT_CLEANUP): save the output status in $at_status_file
16533 and restore it, redirect the AS_MESSAGE_LOG_FD back to
16534 its original place.
16535 (AT_CHECK): since tests are run with a redirected stdout,
16536 and used to be re-run in verbose mode, turn some $at_verbose
16537 into echo, and don't redirect the output of testing stdout
16540 * lib/autotest/autoconf.texi (testsuite Scripts): Update

16661 2003-05-06 Akim Demaille <akim@epita.fr>
16663 Don't try to be smart with aclocal 1.8+ because (i) aclocal no
16664 longer updates aclocal.m4 if useless, (ii) if a file m4_included
16665 by aclocal.m4 is changed it might require the importing of another
16666 m4 extension file, i.e., aclocal must be run.
16668 * bin/autoreconf.in (&run_aclocal, $aclocal_supports_force): New.
16669 (&parse_args): Use --force with aclocal if required and supported.
16670 (&autoreconf_current_directory): Use &run_aclocal.

16680 ($icache_file): New.
16681 (&freeze): Lock the $icache_file.
16683 2003-04-29 Derek Price <derek@ximbiot.com>
16685 * lib/autotest/general.m4 (AT_KEYWORDS): Don't use a comma as the
16686 seperator with m4_append_uniq(). It doesn't work.
16687 (AT_CLEANUP): Add `;' to end of at_help_all.
16688 (AT_INIT): Allow --keywords to be specified more than once. When
16689 grepping $at_help_all for keywords, use the field and keyword
16690 seperators to ensure a complete keyword match. Alter at_prev handling
16691 to support the new --keywords behavior.

16695 * doc/autoconf.texi: Make the dir entries in the autoconf manual
16696 align better with others. I also made some of the individual
16697 entries on one line, for brevity and to make it easier for me to
16698 sort my dir-example file in the Texinfo distribution :).

16765 header causes problems.
16767 2003-03-28 Akim Demaille <akim@epita.fr>
16769 * tests/torture.at (Configuring subdirectories): Require aclocal
16770 1.4, otherwise the test fails, as it does support configure.ac.

16793 * lib/autoconf/general.m4 (AC_ARG_VAR): Use AS_HELP_STRING instead of
16794 obsolete AC_HELP_STRING.
16795 (AC_HELP_STRING): AU_DEFUN to...

16801 2003-03-26 Derek Price <derek@ximbiot.com>
16803 * lib/autotest/general.m4: s/DEFAULT/DEFAULTS/ since it makes more
16804 sense. Verbosify the diversion definitions comment.

16859 * bin/ifnames.in: Add final newline to help and version messages.
16861 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Translate colons,
16862 to cope with DOS-style absolute paths, when constructing
16865 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS, _AC_OUTPUT_FILES):
16866 When constructing paths with IFS=:, quote the path. If we're
16867 constructing a DOS-style absolute path, we don't want to split it
16870 * tests/atspecific.m4 (AT_CHECK_CONFIGURE): Fix typo
16873 2003-02-25 Pavel Roskin <proski@gnu.org>

16890 * doc/autoconf.texi (Limitations of Builtins): Add notes on printf
16891 format starting with "-".
16893 2003-02-20 Alexandre Duret-Lutz <adl@gnu.org>
16895 * doc/autoconf.texi (Limitations of Make): `foo=bar make -e'
16896 is not portable inside Makefile.
16898 2003-02-20 Akim Demaille <akim@epita.fr>
16900 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): When

16913 $ac_prefix_program.
16916 2002-12-23 Paul Eggert <eggert@twinsun.com>
16918 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Define $1 to an
16919 innocuous variant befor including <limits.h> or <assert.h>. This
16920 works around a bug reported by Albert Chin: HP-UX 11i
16921 (and earlier versions) have a <limits.h> that declares
16922 gettimeofday and many other functions.
16924 2002-12-03 Paul Eggert <eggert@twinsun.com>
16928 * NEWS, configure.ac: Update version.
16930 * doc/fdl.texi: Upgrade to FDL version 1.2.
16932 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Use the function f
16933 nontrivially in main's body, so that f's external declaration is
16934 not optimized away in AIX. This should fix the bug reported by
16936 <http://mail.gnu.org/pipermail/autoconf/2002-November/014508.html>.
16938 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C),
16939 _AC_PROG_PREPROC_WORKS_IFELSE): Use <limits.h> if __STDC__ is
16940 defined, to support freestanding compilers. This should fix the
16941 bug reported by Momchil Velkov in
16942 <http://mail.gnu.org/pipermail/autoconf/2002-November/014490.html>.
16944 * doc/autoconf.texi (Obsolete Macros): Fix typos (insert empty
16945 arg, AC_DEFINE -> AC_DEFINE_UNQUOTED) in documentation for

16950 * Makefile.maint (www-gnu): New macro.
16951 (standards.texi-url_prefix, make-stds.texi-url_prefix): Use it, as
16952 the location has moved.

16956 * bin/autom4te.in (at_flatten): rewritten to avoid M4 problem when
16957 \(.*\) match is too long and there is something more to be checked.
16958 <http://mail.gnu.org/pipermail/autoconf/2002-November/014524.html>

16976 Update from masters.
16978 2002-11-14 Akim Demaille <akim@epita.fr>
16980 * Makefile.maint: Sync with Bison, i.e.:
16981 (po-check): Scan .l and .y files instead of the
16982 .c and the .h files that they generate. This fixes the bug
16983 reported by Tim Van Holder in:
16984 <http://mail.gnu.org/pipermail/bison-patches/2002-November/001352.html>
16985 Look for N_ as well as for _. Try to avoid matching #define for
16989 2002-11-14 Akim Demaille <akim@epita.fr>
16991 * doc/autoconf.texi (C Compiler): Compiling several files at once.
16992 From Paul Eggert and Albert Chin-A-Young.
16994 2002-11-14 Akim Demaille <akim@epita.fr>
16996 * doc/autoconf.texi (C Compiler): Solitary backslashes.
16997 From Paul Eggert and Albert Chin-A-Young.
16999 2002-11-14 Kevin Ryde <user42@zip.com.au>
17001 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Initialize f=$1 rather
17002 than assigning in main, to avoid HP cc +O3 optimizing it away.
17004 2002-11-12 Peter Eisentraut <peter_e@gmx.net>
17006 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Add -q
17007 option. Process --recheck after parsing all options. Pass -q
17008 option to configure on --recheck.
17009 (AC_OUTPUT): Pass -q from configure to config.status.
17010 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Strip -q from
17011 arguments to record.
17012 * doc/autoconf.texi (config.status Invocation): Document
17013 config.status -q option.
17015 2002-11-07 Alexandre Duret-Lutz <adl@gnu.org>
17017 * bin/autoscan.in (scan_file): Scan Makefile.am too. Ignore
17018 Makefile.in if Makefile.am exists.
17019 (output): Strip `.am' from Makefiles. Don't
17020 output AC_CONFIG_FILES if no Makefiles were found.
17022 2002-11-07 Akim Demaille <akim@epita.fr>
17024 * Makefile.am (cvs_files): Add elisp-comp, mdate-sh.
17025 (local_updates): New.
17026 * Makefile.maint: Update, from CVS Bison.
17027 (local_updates): New.
17029 2002-11-06 Akim Demaille <akim@epita.fr>
17031 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY): Wrap the `f'
17032 declaration in extern "C" too.
17033 Reported by Roberto Bagnara.

17040 Reported by Ezra Peisach.
17042 2002-11-05 Akim Demaille <akim@epita.fr>
17044 * lib/autoconf/autoheader.m4 (_AH_TEMPLATE_OLD, _AH_VERBATIM_OLD):
17046 We _have_ to stop using the old compatibility scheme that tried to
17047 avoid useless backslashes because Libtool 1.4.3 contains a
17048 AC_DEFINE([error_t], [int],
17049 [Define to a type to use for \`error_t' if it is not
17050 otherwise available.])
17051 We _have_ to quote the single quote and backslashes with \. The
17052 old compatibility scheme saw that ` was backslashed, and therefore
17053 did not quote the single quote. Hence before this patch, Autoconf
17054 was not compatible with Libtool.
17056 2002-11-04 Paul Eggert <eggert@twinsun.com>
17058 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Set the following variables,

17075 (&autoreconf): here.
17076 ($help, $make, &parse_args, &autoreconf_current_directory):
17078 * doc/autoconf.texi (autoreconf Invocation): Adjust.
17080 2002-10-31 Bruno Haible <bruno@clisp.org>
17082 * lib/autoconf/functions.m4 (_AC_FUNC_MALLOC_IF): Change message.

17445 Reported by Alexandre Duret-Lutz.
17447 * bin/autom4te.in (&parse_args): Do not prepend `--reload-state'

17452 (&up_to_date): If a file that was included according to the cache

17467 * lib/Autom4te/General.pm (&update_file): Use `verbose' to report
17468 if some file was changed instead of `print'.
17469 * bin/autoheader.in: Suggest AC_DEFINE with 3 args when needed.

17503 file name to enable parallel executions.
17504 From Sam Varshavchik.
17506 2002-10-08 Akim Demaille <akim@epita.fr>
17508 * bin/autoreconf.in (&autoreconf): Run autopoint before the first
17509 aclocal invocation, as Gettext macros might not be visible to
17511 Instead of blindly running autopoint, scan configure.ac (not the
17512 traces) for AM_GNU_GETTEXT_VERSION uses, as autopoint does.
17513 Reported by Paul D. Smith.
17515 2002-10-08 Paul Eggert <eggert@twinsun.com>
17517 Work around problems found when POSIXLY_CORRECT=1 is set.
17518 None of this seems to have anything to do with POSIX, really,
17519 but it's how Perl getopt works.
17520 * bin/autom4te.in (parse_args): Configure GetOpt with
17522 * doc/autoconf.texi (Invoking autom4te):
17523 --warning -> --warnings.

17545 * tests/torture.at (Configuring subdirectories): Be robust to
17546 users who use config.site to require for a cache: in this case,
17547 the two last configure runs, using two different sets of
17548 arguments, trigger a legitimate error.
17550 2002-09-28 Akim Demaille <akim@epita.fr>

17604 * bin/autoscan.in (&init_tables): Adjust.
17606 2002-09-28 Akim Demaille <akim@epita.fr>
17608 * lib/autoscan/functions, lib/autoscan/headers,
17609 * lib/autoscan/identifiers, lib/autoscan/makevars,
17610 * lib/autoscan/programs: Make the `kind' explicit, i.e., each
17611 `functions' line is now prefixed with `function:'.
17612 * bin/autoscan.in (&init_tables): Adjust.
17614 2002-09-28 Akim Demaille <akim@epita.fr>
17616 From now on, autoscan files must always map a macro name to a
17617 word: there is no `default' macro for autoscan.
17619 * bin/autoscan.in (&init_tables): Reject entries with no macro at
17621 * lib/autoscan/functions, lib/autoscan/headers: Make the macro
17624 2002-09-28 Akim Demaille <akim@epita.fr>
17626 * bin/autoscan.in (%c_keywords): Remove.
17627 (&used): Keep only track of the words we might be interested in.
17628 (&output_kind): It is no longer needed to look for non active

17642 Thanks to Bill Moseley and Paul Eggert.
17643 * lib/m4sugar/m4sh.m4 (AS_TMPDIR): $2 is the directory into which
17644 the tmpdir must be created.
17645 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Have the tmp
17646 dir be in the build tree, instead of $TMPDIR.

17650 * bin/autoscan.in: Improve the comments.
17651 (&parse_args): Drop obsolete undocumented options.

17659 Reported by Ralf Corsepius.
17660 * doc/autoconf.texi (autoreconf Invocation): Likewise.
17662 2002-09-26 Akim Demaille <akim@epita.fr>
17664 Single suffix rules and seperated dependencies are not portable.
17666 * doc/autoconf.texi (Installation Directory Variables): Update.
17667 (Limitations of Make): Some about `Single Suffix Rules and
17668 Separated Dependencies'.
17669 * bin/Makefile.am (autoconf, autoheader, autoreconf, autoupdate)

17672 2002-09-25 Paul Eggert <eggert@twinsun.com>
17674 * BUGS (Interoperability bugs): New section. Mention libtool
17675 1.4.2, configure.ac, and AC_CONFIG_AUX_DIR interoperability bug.
17677 2002-09-24 Paul Eggert <eggert@twinsun.com>
17679 Fix a portability bug reported by Alexandre Duret-Lutz: Solaris 8
17680 make handles suffix-rules differently from GNU make.
17682 * bin/Makefile.am (SUFFIXES, .in): Remove.
17683 (autoconf autoheader autoreconf autoupdate ifnames autoscan autom4te):
17684 Move the body of the old .in rule here.
17686 2002-09-16 Akim Demaille <akim@epita.fr>
17688 i960 compilers create `b.out' files by default.
17689 Reported by Ralf Corsepius.
17691 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT): Remove b.out files.
17692 (_AC_COMPILER_EXEEXT_DEFAULT): Adjust to b.out.
17694 2002-09-13 Paul Eggert <eggert@twinsun.com>
17696 * doc/autoconf.texi (Particular Headers): Remove obsolete
17697 reference to `struct timezone' in the description of

17705 * Makefile.maint: Update from bits of the Coreutils 4.5.1.
17706 * Makefile.am: Adjust.
17708 2002-09-13 Akim Demaille <akim@epita.fr>
17710 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Suggest
17711 reading config.log when the compiler is rejected.
17712 Suggested by Guido Draheim.
17714 2002-09-13 Akim Demaille <akim@epita.fr>
17716 * bin/autoreconf.in: Don't use Cwd::chdir, since in its internals
17717 (chdir_init) might hang when stat'ing mounted directories.
17718 Reported by Vance Shipley.
17720 2002-09-12 Akim Demaille <akim@epita.fr>
17722 * bin/autoscan.in (&parse_args): Pass a reference to the lists, not
17725 2002-09-12 Akim Demaille <akim@epita.fr>
17727 * doc/autoconf.texi (Defining Symbols): Present two different
17728 prototypes for AC_DEFINE and AC_DEFINE_UNQUOTED to emphasize the
17729 difference between 1 argument calls, and 2-3 argument calls.
17731 2002-09-12 Peter Eisentraut <peter_e@gmx.net>
17733 * doc/autoconf.texi: Review grammar and punctuation.
17735 2002-09-11 Paul Eggert <eggert@twinsun.com>
17737 * doc/autoconf.texi: Fix minor formatting, spelling, and
17739 (Defining Symbols): Explain that AC_DEFINE(var) defaults to 1, but
17740 AC_DEFINE(var,,description) does not; and the AC_DEFINE(var) case
17743 2002-09-11 Akim Demaille <akim@epita.fr>
17745 * doc/autoconf.texi (Questions): Rename as...
17747 (Defining Directories): New.
17749 2002-09-09 Akim Demaille <akim@epita.fr>
17751 * doc/autoconf.texi (Making testsuite Scripts): Update.
17752 Suggested by Nishio Futoshi.
17754 2002-09-09 Koji Arai <JCA02266@nifty.ne.jp>
17756 * doc/autoconf.texi (Making testsuite Scripts): Use `@@' where a
17757 plain `@' is wanted.
17759 2002-09-09 Akim Demaille <akim@epita.fr>
17761 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Keep the
17762 `duplicates', since the algorithm was too naive and could keep
17763 `--prefix=1 --prefix=2 --prefix=1' as `--prefix=1 --prefix=2', and
17764 keep `--prefix foo --prefix bar' as `--prefix foo bar'.
17765 Reported by Ralf Corsepius.
17766 * tests/torture.at (Configuring subdirectories): Exercise these
17769 2002-09-09 Akim Demaille <akim@epita.fr>
17771 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Use $srcdir when
17772 looking for a replacement file.
17773 * lib/autoconf/general.m4 (AC_CHECK_DECLS): Check that the
17774 directory is relative.
17775 * doc/autoconf.texi (Generic Functions): Clarify the replacement
17776 directory definition.
17777 Reported by Andreas Schwab and Jim Meyering.
17779 2002-09-06 Akim Demaille <akim@epita.fr>
17781 * doc/autoconf.texi (Setting Output Variables): Clarify what
17782 precious variables are.
17783 Suggested by Pontus Skoeld.
17785 2002-09-05 Akim Demaille <akim@epita.fr>
17787 * bin/Makefile.am (autoconf, autoheader, autoreconf, autoupdate)
17788 (ifnames, autoscan, autom4te): Since we don't only depend on
17789 configure.ac variables (such as VERSION etc.), but also on prefix
17790 and so forth, depend on Makefile, not configure.ac.
17791 Reported by Alexandre Duret-Lutz.
17792 * doc/autoconf.texi (Installation Directory Variables): Adjust.
17794 2002-09-05 Kevin Ryde <user42@zip.com.au>
17796 * doc/autoconf.texi (Limitations of Make): HP-UX trailing backslashes
17797 doesn't seem to be confined to ia64, just say "some versions".
17799 2002-09-04 Akim Demaille <akim@epita.fr>
17801 * Makefile.am, doc/Makefile.am: Remove pdf targets, handled by
17803 * Makefile.am (maintainer-clean-local): Remove.
17804 (MAINTAINERCLEANFILES): Remove COPYING.
17806 2002-09-03 Paul Eggert <eggert@twinsun.com>
17808 * doc/autoconf.texi (Configuration Commands): Remove obsolete
17809 example for AC_CONFIG_COMMANDS_PRE. Problem reported by Marcus
17812 2002-09-03 Akim Demaille <akim@epita.fr>
17814 * configure.ac: Bump to 2.53d.
17815 * Makefile.am (AUTOMAKE_OPTIONS): Require 1.6c, i.e., CVS Automake
17816 as of today, on Automake's team suggestion.
17818 2002-09-03 Akim Demaille <akim@epita.fr>
17822 2002-09-02 Akim Demaille <akim@epita.fr>
17824 * bin/autom4te.in (parse_args): Don't honor AUTOM4TE_PATH and
17826 * configure.ac: Disable SITE_MACRO_DIR.
17828 2002-09-02 Jim Meyering <meyering@lucent.com>
17830 * doc/autoconf.texi (AC_SYS_POSIX_TERMIOS): Reflect renaming: s/am/ac/,
17831 i.e., change am_cv_sys_posix_termios to ac_cv_sys_posix_termios.
17832 Also, tweak grammar: s/make sure to/be sure to/.
17834 2002-09-02 Paul Eggert <eggert@twinsun.com>
17836 * doc/autoconf.texi (Limitations of Builtins): Explain why logical
17837 directory names are generally preferable to physical names.
17839 2002-09-02 Akim Demaille <akim@epita.fr>
17841 * lib/Autom4te/General.pm (&update_file): s/die/error/.
17842 Reported by Raja R. Harinath.
17843 * bin/autoheader.in, bin/autoreconf.in, bin/autoscan.in,
17844 * bin/autoupdate.in: Use error instead of die.
17846 2002-09-01 Paul Eggert <eggert@twinsun.com>
17848 * tests/mktests.sh (ac_exclude_egrep, au_exclude_egrep): Use
17849 ordinary shell concatenation rather than echo+tr+sed command that
17850 runs afoul of a long-line-related sed bug in Solaris 8.
17852 * bin/autoheader.in (parse_args): --warning -> --warnings.
17854 * bin/autoconf.as: Work even if "ls" outputs "FOO not found" to
17855 stdout, as traditional "ls" does.
17856 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT,
17857 _AC_COMPILER_EXEEXT_O): Likewise.
17858 * doc/autoconf.texi (Limitations of Usual Tools): Add "ls".
17860 * bin/autoconf.as: Add --prepend-include option. This patch was
17861 applied to bin/autoconf.in in the 2002-07-17 patch by Mark D. Roth,
17862 but bin/autoconf.in is generated automatically from bin/autoconf.as.
17864 * bin/autoconf.in, configure: Regenerate.
17866 * doc/autoconf.texi (Special Shell Variables): Mention
17867 ENV, MAIL, MAILPATH, PS1, PS2, PS4. Index PWD.
17869 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Unset ENV, MAIL,
17870 MAILPATH and set PS1, PS2, PS4 to default values, to work
17871 around bug in pre-3.0 UWIN ksh reported by Bruce Lilly.
17872 For LC_ALL etc, first try to set to "C" as POSIX requires and as
17873 the Autoconf documentation specifies; fall back to "unset" only if
17874 this fails. Use a shell for-loop for this rather than an m4 loop,
17875 to shorten the output script.
17877 2002-08-30 Paul Eggert <eggert@twinsun.com>
17879 * doc/autoconf.texi (Special Shell Variables): Mention POSIX
17880 1003.1-2001's requirements for CDPATH. Give a simpler workaround
17881 for the CDPATH problem. Document PWD.
17882 (Limitations of Builtins): Document the problem that "cd $foo" and
17883 "ls $foo" may refer to different directories in shells conforming
17884 to POSIX 1003.1-2001. Use PS1 rather than CDPATH for "unset"
17885 example, since the old example is now out of date.
17887 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Reject FOO if "cd
17888 FOO" and "ls FOO" talk about different directories; this catches
17889 problems when POSIX 1003.1-2001 "cd" fails due to symlink
17892 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Use AS_UNSET instead
17893 of rolling our own unset.
17894 (_AS_PREPARE): $as_unset CDPATH instead of AS_UNSETting it, since
17895 in practice we needn't worry about CDPATH if unset doesn't work.
17897 * Makefile.in, aclocal.m4, bin/Makefile.in,
17898 config/Makefile.in, doc/Makefile.in, lib/Makefile.in,
17899 lib/Autom4te/Makefile.in, lib/autoconf/Makefile.in,
17900 lib/autoscan/Makefile.in, lib/autotest/Makefile.in,
17901 lib/emacs/Makefile.in, lib/m4sugar/Makefile.in, man/Makefile.in,
17902 tests/Makefile.in: Regenerate with Automake 1.6.3.
17904 * config/config.guess, config/config.sub, config/mkinstalldirs:
17907 * configure: Regenerate with self.
17909 2002-08-30 Kevin Ryde <user42@zip.com.au>
17911 * doc/autoconf.texi (Limitations of Usual Tools): Notes on "cc"
17914 2002-08-29 Rainer Orth <ro@TechFak.Uni-Bielefeld.DE>
17916 * bin/autom4te.in (Request::load): Correctly test for "do" read
17919 2002-08-29 Akim Demaille <akim@epita.fr>
17921 * lib/Autom4te/General.pm (&xqx): New.
17922 (&xsystem): Use WIFEXITED and WEXITSTATUS instead of decoding $? by
17923 hand, which is not portable.
17925 * bin/autom4te.in: Use them.
17926 Use &error instead of die.
17927 * tests/m4sugar.at (m4_warn, m4_require: circular dependencies):
17930 2002-08-17 Paul Eggert <eggert@twinsun.com>
17932 * lib/autoconf/fortran.m4 (AC_PROG_F77): Remove fc from the
17933 default list of compilers to try, since it was long ago superseded
17934 by the ksh fc builtin. Suggested by Steven G. Johnson.
17936 2002-07-31 Alexandre Duret-Lutz <duret_g@epita.fr>
17938 * doc/autoconf.texi (Invoking autom4te): End the option table,
17939 fixing a bug introduced by the previous patch.
17940 (Limitations of Make): Add a 'target lookup' subentry in the
17941 'VPATH' entry. Rewrite all `make' occurences as `@command{make}'.
17943 2002-07-29 Mark D. Roth <roth@feep.net>
17945 * bin/autom4te.in: Remove --include-envvar and --site-macro-subdir
17946 options and use $AUTOM4TE_PATH.
17947 * doc/autoconf.texi: Remove documentation of autom4te
17948 --include-envvar and --site-macro-subdir options and document
17949 use of $AUTOM4TE_PATH.
17950 * lib/autom4te.in: Remove --include-envvar and --site-macro-subdir
17951 arguments from each language section.
17953 2002-07-29 Paul Eggert <eggert@twinsun.com>
17955 * doc/install.texi: Include copyright symbol in copyright notice.
17957 * Makefile.am (MAKEINFO): Remove; it's a user-specified macro.
17959 (AM_MAKEINFOFLAGS): New macro.
17960 * doc/Makefile.am (MAKEINFO, AM_MAKEINFOFLAGS): Likewise.
17961 * Makefile.am (INSTALL): Use the new macros.
17962 Use -o rather than --output, since "missing" does not grok --output.
17964 2002-07-25 Alexandre Duret-Lutz <duret_g@epita.fr>
17966 * doc/autoconf.texi (Limitations of Make): Escaped newlines in
17967 comments do not always work. Never trust the exit status of
17970 2002-07-24 Kevin Ryde <user42@zip.com.au>
17972 * doc/autoconf.texi (Limitations of Make, Making testsuite Scripts):
17973 Untabify, since tabs are not enjoyed by texi2dvi and makeinfo.
17975 2002-07-23 Paul Eggert <eggert@twinsun.com>
17977 * lib/m4sugar/m4sh.m4 (_AS_PATH_SEPARATOR_PREPARE):
17978 Use PATH="/nonexistent;.", not PATH=".;.", as FreeBSD ksh2002
17979 apparently treats PATH="nonexistent" as if it contained ".".
17980 Bug reported by Stefan `Sec' Zehl.
17982 2002-07-22 Alexandre Duret-Lutz <duret_g@epita.fr>
17984 * doc/autoconf.texi (Limitations of Make): Mention the special
17985 handling of the obj/ directory by BSD make.
17987 2002-07-20 Kevin Ryde <user42@zip.com.au>
17989 * doc/autoconf.texi (Limitations of Make): Add HP-UX IA-64 trailing

18027 description of the tarname default.
18029 2002-07-17 Andreas Buening <andreas.buening@nexgo.de>
18031 * lib/autoconf/functions.m4 (AC_FUNC_FORK): Don't set
18032 ac_cv_func_fork_works before running _AC_FUNC_FORK, do it if the
18033 latter was not run.
18035 2002-07-17 Akim Demaille <akim@epita.fr>
18037 * lib/Autom4te/General.pm (find_file): Browse the directories in
18038 the order they are given.

18050 * bin/autom4te.in: Add --prepend-include, --include-envvar, and
18051 --site-macro-subdir options.

18058 macro directory, remove note that include path directories are

18106 2002-06-27 Paul Eggert <eggert@twinsun.com>

18250 This improves on an earlier suggestion by H. Peter Anvin.
18252 2002-05-16 Paul Eggert <eggert@twinsun.com>
18254 AC_FUNC_FNMATCH now tests only for POSIX compatibility.
18255 AC_FUNC_FNMATCH_GNU also tests for GNU extensions.
18256 Both macros now accept an optional source-dir arg.
18257 New macro AC_GNU_SOURCE to define _GNU_SOURCE.
18259 * NEWS: Document this.
18260 * doc/autoconf.texi (Particular Functions, UNIX Variants): Likewise.
18262 * lib/autoconf/functions.m4 (_AC_FUNC_FNMATCH): New macro.
18263 (AC_FUNC_FNMATCH): Use it. Test only for POSIX conformance,
18264 not for GNU extensions; this undoes part of the 2000-11-03 change,
18265 reverting to 2.13-compatible behavior.
18266 Add new optional argument DIR.
18267 (AC_FUNC_FNMATCH_GNU): New macro.

18271 2002-05-08 Paul Eggert <eggert@twinsun.com>
18273 * lib/autoconf/headers.m4 (AC_HEADER_TIOCGWINSZ):
18274 Don't require AC_SYS_POSIX_TERMIOS. The test is unnecessary,
18275 and it causes a 'test' syntax error if it fails.
18276 Bug reported by Stephen Gildea.
18278 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
18279 If prototypes are supported, use them to check this at compile-time,
18280 instead of trying to check it at run-time. If we must do a run-time
18281 check, assume that setvbuf is standard when cross-compiling, as
18282 nonstandard setvbuf occurs only on ancient and unlikely hosts.
18283 Bug reported by Paul D. Smith.
18285 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Add optional
18286 argument specifying location of getloadavg.c. This removes a
18287 FIXME. This idea was taken from Jim Meyering's implementation in
18289 * doc/autoconf.texi (Particular Functions): Document this.
18290 Also, mention HAVE_NLIST_H rather than NLIST_STRUCT, since
18291 that's what the code does; this fixes a bug reported by
18294 2002-05-03 Akim Demaille <akim@epita.fr>
18296 * bin/autoreconf.in (autoreconf): Rewrite to use Gettext's
18297 autopoint instead of gettextize.
18298 ($uses_alocal): Rename as...
18299 ($uses_aclocal): this.
18300 * doc/autoconf.texi (autoreconf Invocation): Adjust.
18301 Suggested by Bruno Haible.
18303 2002-05-03 Akim Demaille <akim@epita.fr>
18305 * lib/m4sugar/m4sugar.m4 (m4_map_sep): New.
18307 2002-04-29 Paul Eggert <eggert@twinsun.com>
18309 * bin/autoreconf.in (autoreconf): Don't age aclocal.m4's input
18310 files to be 1 second older; just set them to be the same time.
18311 Also, sleep 1 second after the first aclocal, to work around
18312 problems with sub-second time stamps on the input files.
18314 2002-04-29 Thien-Thi Nguyen <ttn@gnu.org>
18316 * doc/autoconf.texi: Mention "set -e -x" lossage
18317 under node "Limitations of Builtins".

18323 From Christian Cornelssen.
18325 2002-04-29 Akim Demaille <akim@epita.fr>
18327 * tests/m4sh.at (LINENO): If testsuite itself is rewritten because
18328 of lack of $LINENO support, then the test will compare the $LINENO
18329 in testsuite vs. the lineno in the test file. This is wrong, of
18331 Be sure to protect it.
18332 Reported by Patrick Welche.
18334 2002-04-25 Akim Demaille <akim@epita.fr>
18336 * doc/autoconf.texi (Obsolete Macros): Typo.
18337 Reported by Vladimir Volovich.
18339 2002-04-25 Akim Demaille <akim@epita.fr>
18341 * bin/autoreconf.in (autoreconf): Don't let aclocal.m4 be older
18342 than some of the input files, hence, on the second run of aclocal,
18343 if some of its input are younger, make them older.
18344 Suggested by Paul Eggert.
18346 2002-04-25 Akim Demaille <akim@epita.fr>
18348 * doc/autoconf.texi (Limitations of Usual Tools): sed and `!'.

18353 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Let ac_subst_files
18354 and ac_subst_vars be sh variables containing the list of
18355 AC_SUBST_FILES'ed and AC_SUBST'ed identifiers. Output them in the
18357 (_AC_INIT_PREPARE): Use them to log them.
18358 (_AC_SUBST, _AC_SUBST_SED_PROGRAM): Remove.
18359 (AC_SUBST, AC_SUBST_FILE): Instead of buliding the
18360 _AC_SUBST_SED_PROGRAM, store the list of output files/variables in
18361 _AC_SUBST_FILES and _AC_SUBST_VARS.
18362 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Adjust.
18364 2002-04-24 Akim Demaille <akim@epita.fr>
18366 * bin/autoreconf.in (autoreconf): Run automake after autoconf and
18367 autoheader, so that automake does not complain about a missing
18368 config.h.in that was to be created.
18370 2002-04-23 Akim Demaille <akim@epita.fr>

18426 importantly, this makes sure that the copyright notices appear in

18566 (AC_PROG_CC): Call _AC_PROG_CC_STDC.
18567 (AC_C_INLINE): Do not require AC_PROG_CC_STDC.
18568 (AC_C_CONST): Same.
18569 (AC_C_INLINE): Same.
18570 (AC_C_PROTOTYPES): Same. Require AC_PROG_CC instead.
18571 * doc/autoconf.texi, NEWS: Document.

18580 2002-03-28 Kevin Ryde <user42@zip.com.au>
18582 * lib/autoconf/c.m4 (AC_C_INLINE): Test with a typedef return value,
18583 to avoid versions of HP C which don't allow that.
18585 2002-03-27 Paul Eggert <eggert@twinsun.com>
18587 * lib/m4sugar/m4sh.m4 (_AS_BASENAME_PREPARE): New macro.
18588 (AS_SHELL_SANITIZE): Invoke it.
18589 (AS_BASENAME): AS_REQUIRE it, and use $as_basename.
18591 2002-03-26 Akim Demaille <akim@epita.fr>
18593 * doc/autoconf.texi (Portable Shell): Add pointers to FAQs.
18595 2002-03-26 Akim Demaille <akim@epita.fr>
18597 * doc/autoconf.texi (Introduction): The GNATS base moved.
18599 2002-03-25 Paul Eggert <eggert@twinsun.com>
18601 * tests/m4sh.at: Don't rely on "PATH=test:$PATH test-1" working
18602 as POSIX requires, as it doesn't work with Zsh.
18603 * doc/autoconf.texi (Assignments): Document the problem.
18605 2002-03-25 Alexandre Duret-Lutz <duret_g@epita.fr>
18607 * doc/autoconf.texi (Limitations of Make): Mention more issue
18608 about VPATH, overriding of macros in sub-makes, and handling of
18611 2002-03-21 Paul Eggert <eggert@twinsun.com>
18613 * doc/autoconf.texi (Here-Documents): Mention Solaris 8 dtksh
18614 problem with here-document buffer boundaries.
18616 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Unset ENV and BASH_ENV
18617 when reinvoking the shell, to work around problems with installers
18618 who put strange things like "cd" commands in their environments.
18620 2002-03-19 Akim Demaille <akim@epita.fr>
18622 * tests/semantics.at (AC_C_BIGENDIAN): s/unknow/unknown/.

18627 * bin/autoscan.in (scan_file): Specify the location in `&used'
18631 2002-03-19 Akim Demaille <akim@epita.fr>

18634 From Nishio Futoshi.
18636 2002-03-19 Akim Demaille <akim@epita.fr>
18638 * lib/m4sugar/m4sugar.m4 (m4_define_default, m4_fst, m4_map): New.

18642 * doc/autoconf.texi (Programming in M4sh): Add AS_MKDIR_P.
18643 (Limitations of Usual Tools): Add mkdir section.
18645 * lib/m4sugar/m4sh.m4 (_AS_MKDIR_P_PREPARE): New macro.
18646 (AS_MKDIR_P): Require it. Use mkdir -p if available, falling
18647 back on AS_DIRNAME to compute prefixes otherwise; this is
18648 roughly what mkinstalldirs does. That way, we need not have
18649 our own filename disassembler. The old disassembler did not
18650 work with Solaris 8 dtksh, which is ksh Version M-12/28/93d.
18652 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP):
18653 Create at_test_all by a series of assignments,
18654 not by a single assignment of a long string. The latter causes ksh
18655 version 11/16/88g to silently misbehave on OpenServer 5.0.6a,
18656 presumably because of a buffer overrun.
18658 2002-03-14 Paul Eggert <eggert@twinsun.com>
18660 * lib/autotest/general.m4 (at_times_skip):
18661 Renamed from at_times. Now a boolean.
18662 ksh93 Version M-12/28/93d doesn't like 'x=times; $x'; it
18663 says 'times: not found'.
18665 2002-03-14 Akim Demaille <akim@epita.fr>
18667 * bin/autoreconf.in (&study_gettextize): New.
18668 (&autoreconf): Handle newest gettextize.
18669 Rerun aclocal if needed.
18670 Suggested by Andreas Schwab.

18692 2002-03-11 Andreas Schwab <schwab@suse.de>
18694 * configure.ac: Explicitly check for EMACS since AM_PATH_LISPDIR
18695 does not do it if --with-lispdir is given.

18704 subdirectory should exist.
18706 2002-03-08 Akim Demaille <akim@epita.fr>
18708 * Makefile.am (AUTOMAKE_OPTIONS): 1.6.
18710 2002-03-08 Akim Demaille <akim@epita.fr>
18712 * bin/autom4te.in (&handle_m4): Do not foreach with `$_' as it
18713 aliases the actual variables, and modifications of the former
18716 2002-03-08 Akim Demaille <akim@epita.fr>
18718 * bin/autom4te.in (&handle_m4): Protect us from corrupted file
18719 because of C-c: have m4 output in tmp files, then mv them.
18721 2002-03-08 Akim Demaille <akim@epita.fr>
18723 * bin/autoconf.in, bin/autoheader.in, bin/autom4te.in,

18740 2002-03-04 Akim Demaille <akim@epita.fr>
18742 * doc/autoconf.texi (AC_LIBOBJ vs. LIBOBJS): New.
18743 * lib/autoconf/general.m4 (AC_INIT): More informative error
18744 message for LIBOBJ.
18746 2002-03-04 Akim Demaille <akim@epita.fr>
18748 * lib/freeze.mk ($(build_libdir)/m4sugar/version.m4): New, for
18751 2002-03-04 Akim Demaille <akim@epita.fr>
18753 * doc/autoconf.texi (Transforming Names): Equality between target
18754 and host is irrelevant.
18755 (Specifying Names, Canonicalizing): Remove all references to the
18756 backward compatibility hooks. Rather, collect them all into...
18757 (Hosts and Cross-Compilation): this new section.
18758 * doc/install.texi (System Type): Ditto.
18759 * lib/autoconf/general.m4 (AC_CANONICAL_HOST): Explicitly state
18760 that `--host' implies cross-compilation.
18762 2002-03-04 Akim Demaille <akim@epita.fr>
18764 * doc/autoconf.texi (Evaluation Macros): New.
18765 * lib/m4sugar/m4sugar.m4 (m4_lquote): Remove, it is totally
18767 (_m4_foreach): Define the variant with immediate evaluation so
18768 that it contains exactly the items, not an expression which
18769 evaluation is the current item.
18770 (m4_re_string, m4_re_word): Don't over quote them.
18772 2002-03-04 Akim Demaille <akim@epita.fr>
18774 Instead of having stacking `shift's evaluated at the end, let
18775 `foreach' loops immediately evaluate them.
18777 * lib/m4sugar/m4sugar.m4 (m4_quote, m4_dquote): Use $@ rather than
18778 $*. This is the n-th time I change my mind, but hopefully this is
18781 (m4_text_wrap): Use m4_foreach, which is finally correct _and_
18783 (m4_foreach_quoted, m4_car_quoted, _m4_foreach_quoted): Remove, as
18784 it was only a hack for m4_text_wrap.
18785 (m4_car2): Remove, replaced by...
18787 (_m4_foreach): Adjust.
18788 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Adjust, and use
18789 m4_bpatsubst for clarification.

18841 AC_PREFIX_PROGRAM fails with dashed program names
18843 * lib/autoconf/general.m4 (AC_PREFIX_PROGRAM): Just use a fresh

18880 2002-02-05 Akim Demaille <akim@epita.fr>
18882 * tests/Makefile.am (check_SCRIPTS): Use it, instead of WRAPPERS,

18905 optional are the sum of the previous files on the command line'.
18906 Also, pass `--reload-state=' on them, so...
18907 (handle_m4): don't.

18909 (M4sh): Rely on M4sugar.

18940 Reported by Alexandre Duret-Lutz and Larry Schmitt.
18942 2002-01-28 Akim Demaille <akim@epita.fr>

18947 2002-01-28 Akim Demaille <akim@epita.fr>
18949 * lib/autotest/general.m4 (AT_INIT): Don't be ridiculous: adjust
18950 AUTOTEST_PATH *after* it was set.
18951 Don't put `.' in the PATH: the user should be precise and `./' if
18952 needed. In addition, given that the test suite does some `cd', if
18953 `.' is in the path, the `tested programs' sections will report
18954 programs found in the test suite's directory, while during the
18955 tests (performed in their own directory), these programs are no
18956 longer visible. In other words, the results is confusing and
18958 * tests/m4sh.at: Adjust: don't rely on `.' being in the PATH.

19005 Autoconf::General::getopt with non valid options.

19009 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Initialize

19027 * tests/Makefile.am (package.m4): New.
19028 EXTRA_DIST it since its a source.
19030 2002-01-06 Akim Demaille <akim@epita.fr>

19033 of PACKAGE_NAME, PACKAGE_TARNAME, PACKAGE_VERSION, PACKAGE_STRING,
19034 and PACKAGE_BUGREPORT from here...
19035 (_AC_INIT_DEFAULTS): to here, since it is unrelated to the
19037 (_AC_INIT_PREPARE): AC_DEFINE these symbols.
19038 * lib/autotest/general.m4: Use AT_PACKAGE_*, not PACKAGE_*.
19039 (AT_INIT): No longer catch `^PACKAGE_(BUGREPORT|STRING)$'.
19040 * tests/tools.at (autoheader): Adjust.

19062 2001-12-14 Akim Demaille <akim@epita.fr>
19064 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): We cleaning up the
19065 trailing files, don't apply `-rf' to files which might not be
19066 created by configure (core, core.*, and *.core), but just `rm -f'.
19067 Suggested by Jonathan Kamens.
19069 2001-12-14 Aaron M. Ucko <amu@alum.mit.edu>

19081 abs_srcdir, top_srcpath to abs_top_srcdir.
19082 (_AC_OUTPUT_FILES): Adjust.
19083 * NEWS, doc/autoconf.texi, lib/autoconf/autotest.m4,
19084 * tests/atspecific.m4, tests/autoreconf.in, tests/tools.at,
19085 * tests/wrappl.in, tests/wrapsh.in: Adjust.
19087 2001-12-12 Steven G. Johnson <stevenj@alum.mit.edu>
19089 * lib/autoconf/fortran.m4 (_AC_PROG_F77_V_OUTPUT): Fix failed
19090 C/Fortran linking on HP/UX, by extracting the Fortran library
19091 search path from the LPATH line in the $F77 -v output.
19093 2001-12-12 Kevin Ryde <user42@zip.com.au>
19095 * doc/autoconf.texi (File Descriptors): Use a clearer layout for the
19096 forbidden file descriptors table.
19098 2001-11-26 Akim Demaille <akim@epita.fr>
19100 * bin/autoscan.in (%c_keywords): Build it at top level.
19101 Map to 1 in order to simplify its uses.
19103 2001-11-26 Akim Demaille <akim@epita.fr>
19105 * bin/autoscan.in (&scan_c_file, &scan_sh_file, &scan_makefile):
19106 Remove $filepath, useless.
19107 (&scan_makefile): Don't remove the $(FOO), ${FOO} and @FOO@
19108 variables, they are really part of the tokens.
19109 Split the input line on spaces and then look for tokens.
19110 Now autoscan ceases to ask for AC_PROG_LEX for the package Bison
19111 because of `lex$U.$(OBJEXT)'.
19112 (&scan_files): Use "@list" instead of join.
19113 * doc/Makefile.am (CLEANFILES): Add *.fns.
19115 2001-11-26 Akim Demaille <akim@epita.fr>
19117 * tests/autoreconf.in, tests/autom4te.in, tests/autoupdate.in:
19118 Remove, replaced by...
19119 * tests/wrappl.in: Be common for all the Perl executables.
19120 In particular autoscan and autoheader want -I.
19121 * configure.ac: Adjust.
19122 * lib/autoscan/headers: errno.h is portable.
19124 2001-11-26 Akim Demaille <akim@epita.fr>
19126 * bin/autoscan.in (used): New.
19129 2001-11-26 Akim Demaille <akim@epita.fr>
19131 * bin/autoscan.in (&scan_c_file): Better parsing of CPP
19133 (&scan_sh_file): Remove a duplicate pattern.
19134 (&check_configure_ac): Use long options.
19135 * lib/autoscan/headers (alloca.h): Check with AC_FUNC_ALLOCA.
19137 2001-11-26 Akim Demaille <akim@epita.fr>
19139 * bin/autoscan.in (scan_c_file): Fix the handling of C comments.
19140 Before, having a line containing the opening of a multi line
19141 comment made the whole line be ignored.
19143 2001-11-26 Akim Demaille <akim@epita.fr>
19145 * doc/autoconf.texi (Using an Autotest Test Suite): New.
19146 (testsuite Scripts): Be one of its subsection.
19147 (Autotest Logs): New.
19149 2001-11-26 Akim Demaille <akim@epita.fr>
19151 Test groups are now run two directories deeper.
19153 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Replace srcdir,
19154 top_srcdir and top_builddir with at_srcdir, at_top_srcdir and
19156 * lib/autotest/general.m4 (AT_INIT): Compute srcdir,
19157 top_srcdir, builddir and top_builddir.
19158 Use `at_*dir' relatively to the directory containing the
19159 suite, use `*dir' when relatively to the current group dir.
19161 2001-11-25 Joseph S. Myers <jsm28@cam.ac.uk>
19163 * doc/autoconf.texi, TODO, lib/autoconf/fortran.m4,
19164 lib/autoconf/functions.m4, lib/autoconf/headers.m4,
19165 tests/atgeneral.m4, tests/tools.at, tests/atspecific.m4: Fix
19168 2001-11-22 Alexandre Duret-Lutz <duret_g@epita.fr>
19170 * doc/autoconf.texi (Using System Type): Add an example of `case
19171 $host' usage so people quit using `case $target' everywhere.
19173 2001-11-22 Akim Demaille <akim@epita.fr>
19175 * doc/autoconf.texi (Installation Directory Variables): Englishoes
19176 spotted by Jim Meyering.
19178 2001-11-16 Paul Eggert <eggert@twinsun.com>
19180 This patch implements a `long double' suggestion by Oliver Kiddle.
19182 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C)): Make the array
19183 static, to catch errors if the value isn't known at compile-time
19184 and the compiler supports dynamic arrays. Change its name from
19185 `_array_' to `test_array' to avoid potential name clashes.
19186 (AC_C_LONG_DOUBLE): Make it a compile-time test, not a run-time
19187 test. Do not define HAVE_LONG_DOUBLE if `long double' is no
19188 better than double. Catch a bug in GCC 2.95.2 x86.
19189 * doc/autoconf.texi (C Compiler): Document the above.
19192 2001-11-13 Akim Demaille <akim@epita.fr>
19194 * tests/m4sh.at (LINENO): Protect from autom4te's substitution by
19196 * tests/tools.at: Don't protect dnl, AT_DATA_M4SH does.
19198 2001-11-13 Akim Demaille <akim@epita.fr>
19200 * lib/autotest/general.m4 (AT_INIT): After having run the test
19201 group, go back to the initial directory, not to at_suite_dir.
19203 2001-11-13 Akim Demaille <akim@epita.fr>
19205 * tests/atspecific.m4 (AT_DATA_M4SUGAR, AT_DATA_M4SH)
19206 (AT_DATA_AUTOCONF): Also protect @&t@ from autom4te.
19207 (AT_CHECK_AUTOCONF, AT_CHECK_AUTOHEADER): Pass no --include
19209 (AT_CHECK_CONFIGURE): Use absolute paths.
19210 (_AT_CHECK_AC_MACRO): Create aclocal.m4 with AC_STATE_SAVE in it.
19211 The problem is still the old one: there is no means in M4 (that I
19212 know about) to create a defining macro, because there is no means
19213 to create `$1' etc., therefore, the defining macro ``swallows''
19214 all the arguments meant to the defined macro.
19216 2001-11-13 Akim Demaille <akim@epita.fr>
19218 * tests/atspecific.m4 (AT_DATA_AUTOCONF): New.
19219 (AT_CONFIGURE_AC): Output the definition of AC_STATE_SAVE in
19221 * tests/aclocal.m4: Remove, as it is no longer used.
19223 2001-11-13 Akim Demaille <akim@epita.fr>
19225 * lib/autotest/general.m4: Change `tests?' into `groups?' in
19226 variable names when referring to a single test group, or to
19227 `suite' when referring to the whole test suite.
19228 `at_last_test' is removed: m4 compute at_format itself.
19229 (at_stdout, at_stder1, at_stderr): New variables.
19230 (AT_CHECK): Use them.
19232 2001-11-13 Akim Demaille <akim@epita.fr>
19234 * lib/autotest/general.m4 (AT_INIT): Be sure to put `.', relative,
19236 Create `testsuite.dir/003/run' instead of `testsuite.003'.
19237 Do it as soon as a test fails, don't wait till the end of the test
19239 Don't remove $as_me.[0-9]*, since these files no longer exist.
19241 2001-11-13 Akim Demaille <akim@epita.fr>
19243 * tests/tools.at: Use absolute paths, since we are no longer run
19246 2001-11-13 Akim Demaille <akim@epita.fr>
19248 Now that tests are running in their own private dir, there is no
19249 need to list the files to remove at the end of tests groups.
19251 * lib/autotest/general.m4 (_AT_CLEANUP_FILE, AT_CLEANUP_FILES):
19252 (AT_data_files, at_data_files): Remove.
19253 (AT_CLEANUP, AT_DATA): Simplify.
19255 Remove the group dir if !debug && !failed.
19256 * tests/atspecific.m4: Adjust.
19258 2001-11-13 Akim Demaille <akim@epita.fr>
19260 Start a new layout for Autotest: `testsuite' creates
19261 `testsuite.dir' in which the at-check-line etc. files are to be
19262 found, and `testsuite.dir/003' where the test group 3 is run.
19264 * lib/autotest/general.m4 (AT_INIT): at_tests_dir,
19265 at_check_line_file, at_format, at_test_normalized, at_group_dir
19267 Create the directories.
19268 Use absolute paths for at- files.
19269 (AT_CHECK): Adjust.
19271 2001-11-11 Michael Matz <matz@kde.org>
19273 * m4sugar.m4 (_m4_foreach): Make it linear instead quadratic.
19275 (m4_car): Properly quote arguments.
19277 2001-11-13 Akim Demaille <akim@epita.fr>
19279 * tests/aclocal.m4 (AC_STATE_SAVE): s/LIBOBJS/LIB@&t@OBJS/ to cope
19280 with stricter rules on LIBOBJS.
19282 2001-11-12 Paul Eggert <eggert@twinsun.com>
19284 * lib/autoconf/c.m4 (AC_C_PROTOTYPES): Define __PROTOTYPES too.
19285 * doc/autoconf.texi (C Compiler): AC_C_PROTOTYPES now defines
19288 2001-11-12 Akim Demaille <akim@epita.fr>
19290 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT): Use AC_CHECK_FUNCS.
19292 2001-11-12 Akim Demaille <akim@epita.fr>
19294 * lib/autoconf/c.m4, lib/autoconf/fortran.m4,
19295 * lib/autoconf/functions.m4, lib/autoconf/general.m4,
19296 * lib/autoconf/headers.m4, lib/autoconf/libs.m4,
19297 * lib/autoconf/programs.m4, lib/autoconf/specific.m4,
19298 * lib/autoconf/types.m4: When invoking AC_DEFINE and friends,
19299 specify to what the macro should be defined (typically to 1).
19301 2001-11-12 Akim Demaille <akim@epita.fr>
19303 * lib/autoconf/functions.m4 (AC_FUNC_STRTOD): AC_SUBST POW_LIB.
19306 2001-11-12 Akim Demaille <akim@epita.fr>
19308 * lib/autoconf/programs.m4 (_AC_PROG_LEX_YYTEXT_DECL): Use
19309 AC_TRY_EVAL to run $LEX, not AC_TRY_COMMAND. This validates the
19310 definition used by Automake where LEX is +/- "${missing} lex" and
19311 `missing' itself contains variables.
19313 2001-11-12 Akim Demaille <akim@epita.fr>
19315 * lib/autotest/general.m4 (AT_INIT): Push KILL at the end.
19316 Now that M4sh pushes BODY, the comments were output at the end of
19319 2001-11-08 Akim Demaille <akim@epita.fr>
19321 * bin/autoreconf.in (&autoreconf): Run aclocal before tracing, so
19322 that we can trace macros from aclocal.m4.
19323 Trace AC_PROG_LIBTOOL, not AM_PROG_LIBTOOL, since the latter is
19324 obsoleted, and redirect to the former anyway.
19325 Reported by Ralf Corsepius.
19327 2001-11-08 Akim Demaille <akim@epita.fr>
19329 * bin/autoreconf.in (&autoreconf): AC_CONFIG_SUBIDRS are to be
19330 processed only if present.
19331 * tests/torture.at (Configuring subdirectories): Use autoreconf
19332 instead of successive calls to autoconf.
19333 Add a nonexistent subdirectory to exercise the patch above.
19334 Reported by Ralf Corsepius.
19336 2001-11-08 Kevin Ryde <user42@zip.com.au>
19338 * doc/autoconf.texi (Limitations of Usual Tools): Note HP-UX cc
19339 doesn't accept .S files.
19341 2001-11-07 Akim Demaille <akim@epita.fr>
19343 * lib/m4sugar/m4sugar.m4 (m4_pattern_forbid): Accepts $2.
19344 * lib/autoconf/general.m4 (AC_INTI): Forbid LIBOBJS.
19345 (_AC_LIBOBJ): s/LIBOBJS/LIB@&t@OBJS/.
19346 * bin/autom4te.in (warn_forbidden): New.
19347 (handle_output): Use it.
19348 Read m4_pattern_forbid with messages.
19350 2001-11-05 Akim Demaille <akim@epita.fr>
19352 * bin/autom4te.in (--normalize): Remove.
19353 * lib/autom4te.in: Adjust.
19355 2001-11-05 Akim Demaille <akim@epita.fr>
19357 * tests/Makefile.am (testsuite): Rename this target as...
19358 ($(TESTSUITE)): this.
19361 2001-11-05 Alexandre Duret-Lutz <duret_g@epita.fr>
19363 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): When removing
19364 the --prefix option, also remove it's argument.
19366 2001-11-05 Akim Demaille <akim@epita.fr>
19368 * doc/autoconf.texi (testsuite Invocation): Update.
19369 (Writing testsuite.at): Update.
19371 2001-11-03 Akim Demaille <akim@epita.fr>
19373 * doc/autoconf.texi: s/@code/@command/ where appropriate.
19375 2001-11-03 Akim Demaille <akim@epita.fr>
19377 * lib/Autom4te/General.pm: (&catfile, &canonfile)
19378 (&file_name_is_absolute): New, wrappers around routines from
19380 Use and export them.
19381 (&find_configure_ac): Optionally take a directory where to look at.
19382 * bin/autoreconf.in (&parse_args): Trim the configure.ac part of
19384 Default @ARGV to `.', not find_configure_ac.
19385 (&autoreconf): Argument is a directory.
19386 Trace AC_CONFIG_SUBDIRS and schedule the subdirs for autoreconf'ing.
19387 * doc/autoconf.texi (autoreconf Invocation): Update.
19389 2001-11-03 Akim Demaille <akim@epita.fr>
19391 * lib/Autom4te/General.pm (@export_vars, @export_subs)
19392 (@export_forward_subs): New.
19393 Add basename, dirname, and fileparse.
19395 * bin/autoreconf.in (&autoreconf): Fix call to fileparse.
19396 Don't look for aclocal flags if we already know aclocal is not
19398 Move aclocal.m4t only if it exists.
19399 Reported by Ezra Peisach.
19401 2001-11-03 Akim Demaille <akim@epita.fr>
19403 * bin/autoreconf.in (&parse_args): Work only on the configure.ac
19404 passed on command line, defaulting to ./configure.ac if present.
19405 (&maybe_autoreconf, File::Find): Remove, unused.
19406 (&autoreconf): If autoconf is not used, don't try to trace.
19408 2001-11-02 Akim Demaille <akim@epita.fr>
19410 * configure.ac: Bump to 2.52g.
19412 2001-11-02 Akim Demaille <akim@epita.fr>
19416 2001-11-02 Akim Demaille <akim@epita.fr>
19418 * config/config.guess, config/config.sub, doc/standards.texi:
19419 * config/lispdir.m4: Update from masters.
19420 * configure.ac: Bump to 2.52f.
19422 2001-11-02 Akim Demaille <akim@epita.fr>
19424 * bin/autoreconf.in (&autoreconf): Set `$aclocal_flags' to ''.
19425 Don't run aclocal when aclocal.m4 is not from aclocal.
19427 Don't run libtoolize and gettextize if --install is not given.
19429 2001-11-01 Paul Eggert <eggert@twinsun.com>
19431 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): _AS_CR_PREPARE needs to
19432 be invoked before _AS_LINENO_PREPARE.
19433 (_AS_LINENO_PREPARE): Use as_cr_digits and as_cr_alnum rather
19434 than character ranges.
19436 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Fix NLS before
19437 invoking AS_BASENAME. Set the locale variables to 'C' if
19438 possible, as POSIX requires this to get the traditional
19440 * doc/autoconf.texi (Special Shell Variables): Describe the above.
19442 2001-10-31 Paul Eggert <eggert@twinsun.com>
19444 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): Do not surround body
19445 with {}, as that triggers a bug in Bash 2.05.
19447 (_AS_LINENO_PREPARE): Use Sed rather than
19448 Awk. Fix the sed prepass to work even if there are multiple
19449 instances of $LINENO on the same line. Do not substitute for
19450 other variables like $LINENOT. Do not check file dates; such a
19451 check is unreliable on sufficiently fast machines, and removing
19452 the check makes the code simpler and more reliable. Check for
19453 output and chmod failures.
19455 * doc/autoconf.texi (Special Shell Variables): Document
19458 2001-10-31 Akim Demaille <akim@epita.fr>
19460 * tests/Makefile.am (atconfig): Remove this target, Automake
19463 2001-10-31 Akim Demaille <akim@epita.fr>
19465 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Do not
19466 AC_CONFIG_FILES(atlocal) as it means a file atlocal.in *must* be
19467 provided, while it is optional.
19468 * configure.ac: Adjust.
19470 2001-10-26 Paul Eggert <eggert@twinsun.com>
19472 * NEWS, README, configure.ac, lib/Autom4te/General.pm,
19473 lib/Autom4te/Struct.pm:
19474 Require Perl 5.005_03 instead of just 5.005, as some tests fail
19477 * doc/autoconf.texi (Special Shell Variables): Document some
19478 more LINENO gotchas, particularly with respect to the Awk+Sed hack.
19480 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): New macro.
19481 (_AS_LINENO_PREPARE): Use it instead of shell eval, since
19482 eval $LINENO is not portable in practice.
19484 2001-10-24 Akim Demaille <akim@epita.fr>
19486 * lib/Autom4te/General.pm (backname): New.
19488 2001-10-24 Akim Demaille <akim@epita.fr>
19490 * m4/: Remove, merged into...
19493 2001-10-23 Tim Van Holder <tim.van.holder@pandora.be>
19495 * doc/autoconf.texi (Shellology): Mention the problems with bash
19496 2.05's use of ANSI quoting in its `set' builtin.
19498 2001-10-22 Paul Eggert <eggert@twinsun.com>
19500 * lib/autoconf/functions.m4 (AC_FUNC_STRERROR_R):
19501 Rename ac_cv_func_strerror_r_works to ac_cv_func_strerror_r_char_p,
19502 and rename HAVE_WORKING_STRERROR_R to STRERROR_R_CHAR_P, since
19503 POSIX decided to standardize on the int flavor of strerror_r.
19504 Always do char* test, as there's no reason not to.
19505 Assign to a char* var, to catch strerror_r that returns int*.
19507 * doc/autoconf.texi (Particular Functions):
19508 Document the above changes. Also, document the fact that
19509 AC_FUNC_STRERROR_R defines HAVE_DECL_STRERROR_R.
19511 * NEWS: Mention HAVE_WORKING_STRERROR_R -> STRERROR_R_CHAR_P.
19513 2001-10-20 Akim Demaille <akim@epita.fr>
19515 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): The name of
19516 the executable was missing from the log.
19518 2001-10-20 Akim Demaille <akim@epita.fr>
19520 * lib/Autom4te/General.pm (&update_file): If destination is
19521 unchanged, remove the source.
19522 (&up_to_date_p): Don't be verbose, be debug.
19523 * bin/autoreconf.in: No longer support --m4dir.
19524 (&autoreconf): Display the full path of the configure.ac we are
19526 Trace it only once.
19527 Be sure to honor --force with gettextize.
19528 Always run aclocal.
19529 * doc/autoconf.texi: Adjust.
19531 2001-10-20 Akim Demaille <akim@epita.fr>
19533 * bin/autoheader.in ($localdir, $m4, $SIMPLE_BACKUP_SUFFIX):
19535 * bin/autoreconf.in (&autoreconf): Do not run gettextize when
19536 `intl' is already present, as it refuses unless --force.
19537 (&parse_args): Use -I, --include instead of the old Autoconf
19539 ($localdir, $autoconf_dir): Remove.
19541 (&maybe_autoreconf): New, to preserve $_ for File::Find.
19543 2001-10-19 Jens Petersen <petersen@redhat.com>
19545 * lib/autoconf/programs.m4 (AC_PROG_AWK): Prefer gawk to mawk.

19555 2001-10-19 Akim Demaille <akim@epita.fr>
19557 * lib/emacs/autoconf-mode.el, lib/emacs/autotest-mode.el: In a
19558 comment, explain how to install automatic mode selection.
19561 2001-10-19 Ezra Peisach <epeisach@zif.mit.edu>
19563 * bin/autoreconf.in (autoreconf): Display the path to the
19564 configure.ac being studied.
19566 2001-10-18 Paul Eggert <eggert@twinsun.com>
19568 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Cast sizeof to unsigned
19569 long, to work around a bug in the HP C compiler version HP92453-01

20031 2001-09-19 Akim Demaille <akim@epita.fr>
20033 * lib/autotest/general.m4: Englishoes.
20034 From Tim Van Holder and Alexey Mahotkin.
20036 2001-09-18 Paul Eggert <eggert@twinsun.com>
20038 * doc/autoconf.texi (Common Shell Constructs): New node,
20039 documenting AS_DIRNAME.
20040 (Limitations of Usual Tools): Refer to it when discussing dirname.
20041 Also, update discussion of POSIX standard to reflect latest draft.
20043 * lib/autoconf/c.m4:
20044 (AC_LANG_INT_SAVE(C)): Also support negative values, down to LONG_MIN.
20046 * lib/autoconf/general.m4 (_AC_COMPUTE_INT_COMPILE):
20047 Do not pass a first argument with leading '-'
20048 to expr, by parenthesizing initial integers that might be negative.
20050 * doc/autoconf.texi (Particular Functions): AC_FUNC_GETPGRP
20051 now merely checks whether it is an error to pass an argument
20054 * lib/autoconf/functions.m4 (_AC_FUNC_GETPGRP_TEST): Remove.
20055 (AC_FUNC_GETPGRP): Don't bother with a runtime test. Just check
20056 whether it is a (compile-time) error to pass an argument to
20057 getpgrp. This simpler test supports the revised documentation,
20058 and is all that AC_FUNC_GETPGRP's users really need.
20060 2001-09-18 Akim Demaille <akim@epita.fr>
20062 * doc/autoconf.texi (Limitations of Make) <$<>: New.

20070 2001-09-18 Paul Wagland <paul@wagland.net>
20072 * tests/m4sh.at: Ensure that AS_DIRNAME handles '/', '//' and '///'
20074 Add test for AS_BASENAME.
20075 * lib/m4sugar/m4sh.m4: Fix AS_BASENAME so that it passes the previous
20076 added test. It now correctly handles /1/2/3/, returning '3' not ''.
20077 Added AS_BASENAME_SED to make the interface the same as AS_DIRNAME.
20078 * tests/base.at: Fixed the expected responses. The old ones were
20080 * lib/autoconf/general.m4: Fixed AC_PREFIX_PROGRAM, it now behaves as
20081 the documentation claims it should (and how it behaved in 2.13).
20083 2001-09-18 Akim Demaille <akim@epita.fr>
20085 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): No INIT-CMDS in
20086 the AC_CONFIG_COMMANDS invocation.
20087 This also solves the name clash problems.
20088 Don't set the package's ID.
20089 * lib/m4sugar/Makefile.am (version.m4): Revamp.
20090 No longer to be shipped.
20091 (version.in): Remove.
20092 * lib/m4sugar/m4sugar.m4, lib/autoconf/general.m4,
20093 * lib/autoconf/status.m4: Adjust.
20094 Use `m4_PACKAGE_STRING'.
20095 * lib/autotest/general.m4 (AT_INIT): N-th signature change: now
20096 the only optional argument is the name of the test suite.
20097 Expect `package.m4' to define the package signature.
20098 * lib/autom4te.in (Autotest): Add `package.m4?'.
20099 * tests/Makefile.am (package.m4): New.
20100 * tests/suite.at: ifnames is a victim.
20102 2001-09-18 Akim Demaille <akim@epita.fr>
20104 * lib/autom4te.in (Autoconf): Preselect AM_CONDITIONAL,
20105 AC_LIBSOURCE, AC_CONFIG_FILES.
20106 * lib/autotest/general.m4 (AT_INIT): Don't abort when a tested
20107 program version string doesn't match the package's.
20108 * lib/autoconf/general.m4 (AC_CACHE_VAL): Reestablish the space
20111 2001-09-17 Paul Eggert <eggert@twinsun.com>
20113 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):
20114 Allow expression to return any value that can fit into unsigned long
20115 (not int, as before). Check for output errors.
20117 2001-09-17 Bruno Haible <haible@ilog.fr>
20119 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):
20120 Always include <stdio.h> and <stdlib.h>. Evaluate
20121 the expression in an extra function before these includes. Call
20122 fprintf "%d" only after ensuring the argument is of type 'int'.
20123 Reported by Wayne Chapeskie <waynec@spinnaker.com>.
20125 2001-09-17 Paul Eggert <eggert@twinsun.com>
20127 Fix bug reported by Paul Townsend on AIX 4.3.3.0 with CFLAGS=-O4
20128 or CFLAGS=-O5. In that case, the linker has a relaxed view of
20129 fatal errors, and AC_CHECK_LIB causes it to include libraries even
20130 when they don't exist.
20132 * lib/autoconf/headers.m4 (AC_HEADER_DIRENT): Use AC_SEARCH_LIBS,
20133 not AC_CHECK_LIB, so that we don't use -ldir or -lx if we don't
20136 * lib/autoconf/specific.m4 (AC_ISC_POSIX): Replace the old, crufty
20137 version with the version used by fileutils 4.1, except use
20138 AC_SEARCH_LIBS, not AC_CHECK_LIB, so that we don't use -lcposix if
20141 * doc/autoconf.texi (AC_ISC_POSIX): Describe new behavior.
20143 2001-09-13 Akim Demaille <akim@epita.fr>

20183 * lib/autotest/general.m4 (AT_INIT): Create and remove
20184 `$as_me.[0-9]+' instead of `debug-[0-9]+.sh', so that multiple
20185 test suites can cohabit.
20187 2001-09-13 Akim Demaille <akim@epita.fr>
20189 * tests/mktests.sh: Don't output banners for empty test files.

20241 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Don't pass

20244 * lib/autoconf/programs.m4 (AC_SHELL_PATH_WALK): Use PATH_SEPARATOR.

20288 to avoid GCC warnings.
20291 2001-09-05 Akim Demaille <akim@epita.fr>

20295 2001-09-05 Akim Demaille <akim@epita.fr>
20297 Be ready to handle filenames as stupid as `dnl.at', for if even
20298 the maintainer is dumb enough to do that...
20300 * lib/autotest/general.m4 (AT_SETUP, AT_LINE): Demonstrates your
20301 excellence in M4 quotation: consider `__file__' is active.
20303 And BTW, when invoking m4, pass the --include in the right order:
20306 * bin/autom4te.in, bin/autoupdate.in: Use reverse when kingtal to

20334 New, extracted from main.
20335 Use IO::File wherever possible.

20338 Don't invoke `_au_disable', since ac was not loaded, but just

20368 * doc/autoconf.texi (Quadrigraphs): Document `@&t@'.
20369 (testsuite Scripts): There is no such thing as `atconfig.in'.
20370 And actually one diagram is missing: test suite runtime.
20372 2001-08-31 Akim Demaille <akim@epita.fr>
20374 * lib/Autom4te/General.pm (&find_file): Browse the includes in the
20377 2001-08-31 Akim Demaille <akim@epita.fr>
20379 * bin/autoupdate.in (@include): `installcheck' revealed the path
20380 to m4sugar was lacking!
20382 2001-08-31 Akim Demaille <akim@epita.fr>
20384 * man/Makefile.am (.x.1): We really have to pass
20385 autom4te_perllibdir.

20389 * lib/autotest/general.m4 (AT_INIT): Don't pass all the args to
20390 debug scripts, in particular passing explicitly listed tests to

20395 * bin/autom4te.in (&parse_args): Strip `.' from `@include'.
20396 * bin/autoupdate.in: Use --include, -I, and --force, -f, too.
20397 Use directly autom4te, not autoconf.

20439 Drop AC_MACRODIR dead for real.
20440 * tests/atspecific.m4 (AT_CHECK_AUTOHEADER): Now autoheader says
20441 `autoheader: `config.hin' is created'.
20442 * tests/tools.at (Syntax of the Perl scripts): Check autoheader.
20444 2001-08-31 Akim Demaille <akim@epita.fr>
20446 * bin/autoheader.in: Rewrite in Perl.

20449 2001-08-31 Akim Demaille <akim@epita.fr>
20451 * bin/autoconf.in (--include, -I): New option.
20452 Map --localdir, --autoconf-dir onto it.
20453 Forward autom4te's options instead of interpreting them.
20454 * bin/autoconf.in, bin/autoheader.in (AC_MACRODIR, autoconf_dir):
20455 There is no such envvar since the inception of autom4te.cfg.
20456 * bin/autom4te.in (&parse_args): Uniquify `@include'.
20457 * bin/autoupdate.in: Adjust, and perform more control.

20459 * tests/autoconf: Dittowise.
20461 2001-08-31 Akim Demaille <akim@epita.fr>

20477 * lib/Autom4te/General.pm (&find_peer): Remove.
20478 * lib/autotest/general.m4 (AT_INIT): `AUTOTEST_PATH=a:b' gives
20479 `abuild:asrc:bbuild:bsrc', not `abuild:bbuild:asrc:bsrc'.
20480 * man/Makefile.am: Let help2man rely on PATH instead of trying to
20481 find the executables for it.
20482 * tests/Makefile.am: Major cleanup. Too lazy to document...
20483 * tests/atlocal.in: Remove all the obscure envvar manipulations.
20485 * tests/atspecific.m4, tests/tools.at: Passing --localdir is
20486 indeed related to running the test suite, while passing
20487 --autoconf-dir and others is related to running non installed
20488 Autoconf executables. So don't do that, leave it to...
20489 * tests/autoconf, tests/autoheader, tests/autom4te, tests/autoupdate,
20490 * tests/autoscan: New.
20491 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): Don't
20492 refer to library files: rely on --language.
20494 2001-08-29 Akim Demaille <akim@epita.fr>

20980 2001-08-15 Akim Demaille <akim@epita.fr>
20982 * bin/autom4te.in (@m4_warning): New.
20983 (&handle_m4): Use it.
20984 * tests/m4sugar.at (m4_warn): Pass `-f' to autom4te to ensure the
20985 warnings are issued at each run.
20986 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): M4sugar
20987 is in the src tree.
20989 2001-08-15 Akim Demaille <akim@epita.fr>

21054 2001-08-11 Alexandre Duret-Lutz <duret_g@epita.fr>
21056 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Handle ACTION-IF-TRUE,
21057 ACTION-IF-FALSE, and ACTION-IF-UNKNOWN.
21058 * doc/autoconf.texi (C Compiler Characteristics): Update
21059 documentation for AC_C_BIGENDIAN.
21061 2001-08-11 Alexandre Duret-Lutz <duret_g@epita.fr>
21063 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Guess endianness by grep'ing
21064 magic values from an object file when cross-compiling.
21065 Based on code by Guido Draheim <Guido.Draheim@gmx.de>.
21067 2001-08-10 Akim Demaille <akim@epita.fr>
21069 * bin/autom4te.in (&handle_output): Don't use `grep' with side
21071 Suggested by Russ Allbery.
21073 2001-08-10 Ralf Corsepius <corsepiu@faw.uni-ulm.de>
21075 * lib/autoconf/general.m4 (_AC_OUTPUT_SUBDIRS): Propagate the
21076 current $prefix to the sub-configures.
21078 2001-08-09 Tim Van Holder <tim.van.holder@pandora.be>
21080 * lib/autoconf/lang.m4: Ignore *.xSYM when looking for an executable
21081 extension (needed on BeOS). Reported by Guido van Rossum.
21083 2001-08-09 Akim Demaille <akim@epita.fr>
21085 * bin/autom4te.in ($icache): Load it only if older than autom4te.
21087 2001-08-07 Akim Demaille <akim@epita.fr>
21089 * lib/autotest/general.m4 (AT_INIT): All the `at-*' are to be
21091 (at-setup-line): Huh? Be a variable `at_setup_line', not a file.
21092 No need to remove the files before and after the each test, before
21093 each test and at the end of the suite is enough.
21094 Display only the children `times', not the shell's.
21095 If the test failed or was skipped, at-times is not available.
21097 2001-08-07 Akim Demaille <akim@epita.fr>
21099 Always produce testsuite.log, including when there are no
21100 failures. This helps getting information on skipped tests, and
21101 duration of the tests. Err, implement the latter btw.
21103 * lib/autotest/general.m4 (AT_INIT): Set up fd 6 for the log.
21104 Dump information on the first run of each test.
21105 (AT_CLEANUP): Create `at-times' containing the duration of the
21108 2001-08-07 Akim Demaille <akim@epita.fr>
21110 The use of `dumpstat' revealed that `len' was used although it
21111 should not. m4_text_wrap was using it, but in the Autoconf world
21112 where it is legal. Hence (i) test M4sh in its own world, not
21113 Autoconf's, and (ii), ahem, fix the bug :)
21115 * lib/autotest/general.m4: Be sure the set good quotes, as tracing
21116 does not like `' instead of [].
21117 (AT_INIT): Forbid `^_?AT_'.
21118 And don't output such tokens.
21119 * tests/Makefile.am (CLEANFILES): Add `script', `script.s4g',
21120 `script.as', and `autom4te.cache'.
21121 Remove `empty' and `macro' which are no longer used.
21122 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): New.
21123 * tests/m4sugar.at: Use it.
21124 * lib/m4sugar/m4sugar.m4: Use `m4_len' not `len'.
21126 2001-08-07 Akim Demaille <akim@epita.fr>
21128 * bin/autoconf.in, bin/autoheader.in: --force, -f is a new option.
21130 2001-08-07 Alexandre Duret-Lutz <duret_g@epita.fr>
21132 * bin/autom4te.in (handle_output): Typo in quadrigraph substitution.
21134 2001-08-04 Akim Demaille <akim@epita.fr>
21136 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA, AC_FUNC_ERROR_AT_LINE)
21137 (AC_FUNC_FSEEKO, AC_FUNC_OBSTACK): Use AC_LANG_IFELSE, not
21139 * lib/autoconf/headers.m4 (AC_HEADER_MAJOR): Likewise.
21140 * lib/autoconf/fortran.m4 (_AC_LANG_PROGRAM_C_F77_HOOKS)
21141 (AC_F77_MAIN): Likewise.
21143 2001-08-04 Akim Demaille <akim@epita.fr>
21145 Don't rely on M4sugar outputting the patterns in files, since we
21146 might process the output _without_ running m4, hence without these
21149 * lib/m4sugar/m4sugar.m4 (m4_init): No need for `m4_tmpdir'.
21150 * bin/autom4te.in (@Request::includes): Remove, unused.
21151 (@Request::source): Rename as...
21152 (@Request::input): this.
21153 (@preselect): Add `m4_pattern_forbid' and `m4_pattern_allow'.
21154 (&handle_output): Fetch the patterns from the traces.
21155 `$forbidden' and `$allowed' are constant: use m//o.
21156 (&handle_m4): M4sugar no longer wants `m4_tmpdir'.
21157 (m4_pattern_forbid, m4_pattern_allow): Adjust for tracing only.
21159 2001-08-04 Akim Demaille <akim@epita.fr>
21161 `autoconf && autoheader' is sped up. Now, speed up `autoheader &&
21162 autoconf', i.e., in addition to caching traces, cache the output.
21164 * bin/autom4te.in (Request::cache): Rename as...
21165 (Request::id): this.
21166 ($cache, $icache, $tcache, $ocache): New.
21167 (&handle_m4): Save M4 output in the cache instead of $tmp.
21168 (&handle_output): Adjust.
21169 (&up_to_date_p): Check that the output cache is up to date too.
21170 (top level): Run `&handle_m4' iff force or the cache is invalid.
21171 Run `&handle_output' if the output cache is more recent.
21173 2001-08-04 Akim Demaille <akim@epita.fr>
21175 * bin/autom4te.in ($force): New.
21176 (&parse_args, &print_usage): -f, --force is a new option.
21177 (&handle_output): CPP directives might have spaces after `#'.
21178 (&parse_args): The first file only can be frozen.
21180 2001-08-04 Akim Demaille <akim@epita.fr>
21182 Don't let autom4te compute the `include' traces several times:
21183 first check that the trace cache file is up to date, and then
21184 compare its timestamp with that of the output.
21186 * bin/autom4te.in, bin/autoupdate.in, bin/autoscan.in: Normalize
21187 the preamble. Don't require 5.005 as Autom4te::General does it,
21188 and better yet (use `use', not `require'!).
21189 * lib/Autom4te/Struct.pm: Rename the last occurrences of
21190 Class::Struct as Autom4te::Struct.
21191 * lib/Autom4te/General.pm (File::stat): Use it.
21192 (&mtime): New, export it.
21193 * bin/autom4te.in: Use it.
21194 Declare `$req' is invalid if it is outdated.
21195 Don't declare it valid before saving it if something went wrong.
21197 2001-08-04 Akim Demaille <akim@epita.fr>
21199 Autom4te shall not encode Autoconf data, and preselecting traces
21200 must be proposed to the users.
21202 * bin/autom4te.in (@required_trace): Remove.
21204 (&parse_args, &print_usage): -p, --preselect is a new option.
21205 (&up_to_date_p): Adjust.
21206 * bin/autoconf.in: Preselect some Autoconf macros.
21208 2001-08-04 Akim Demaille <akim@epita.fr>
21210 * tests/tools.at (autoconf --trace: user macros): Check traces on
21211 macros invoked without arguments, and macros invoked with multiple
21214 2001-08-03 Alexandre Duret-Lutz <duret_g@epita.fr>
21216 * bin/autom4te.in (handle_traces): Fix rewriting of traces without
21219 2001-08-03 Akim Demaille <akim@epita.fr>
21221 * bin/autoconf.in ($@): Work around the usual sh bug.
21224 2001-08-03 Akim Demaille <akim@epita.fr>
21226 Clean up the handling of the M4 builtins tracing exception.
21228 * bin/autom4te.in (Request::request): Don't complete M4 builtins

21231 (@m4_builtin): this.
21232 (%m4_builtin_alternate_name): New.
21233 (&parse_args): Complete the trace requests with alternate names.

21245 (m4_divert_pop): Dump the whole diversion stack when a diversion
21247 * bin/autom4te.in (&handle_output): Remember of the first
21248 occurrence of a possibly undefined macro, not the last.
21249 Complain about the possibly undefined macros in the same order as
21250 the appear in the output.
21251 * lib/autoconf/Makefile.am (autoconf.m4f): List its dependencies.
21252 * tests/tools.at (autoconf: forbidden tokens, basic)
21253 (autoconf: forbidden tokens, exceptions): No longer sort
21254 autoconf's stderr, as it is now deterministic.
21255 Check that `dnl' is caught.
21257 2001-08-01 Akim Demaille <akim@epita.fr>
21259 * configure.ac: Bump to 2.52c.

21276 * bin/autoconf.in, bin/autom4te.in, bin/autoupdate.in: Remove your
21277 `END', as `Autom4te::General::END' will be triggered.
21278 * bin/autoupdate.in, bin/autoscan.in: Improve error messages accuracy.
21279 * bin/autoupdate.in (File::Compare, File::Copy): Use them instead of
21280 system to run `mv', `rm', and `cmp'.

21284 * lib/Autom4te/General.pm (&unique): New.
