5992 forks when sanitizing PATH. Always output machine information,
5993 not just when atconfig was located.
5995 Add 'testsuite -C dir'.
5996 * lib/autotest/general.m4 (_AT_ARG_OPTION): Move missing argument
5998 (AT_INIT) <PARSE_ARGS_END>: ...here, since -k always takes
6000 <DEFAULTS>: Delay computation of variables based on $at_dir...
6001 <PREPARE_TESTS>: ...to here, since -C can change $at_dir.
6002 <TESTS>: Re-invoke via absolute name, since -C may be in effect.
6003 <PARSE_ARGS>: Parse new option.
6004 <HELP_TUNING>: Document it.
6005 * tests/autotest.at (Choosing where testsuite is run): New test
6007 (Keywords and ranges): Add test for missing -k argument.
6008 * NEWS: Document this.

6018 2008-01-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6020 * doc/autoconf.texi (Particular Programs): Do not mention the
6021 Autoconf version in which the AC_PROG_INSTALL change was done.
6022 Suggested by Paul Eggert.
6024 2008-01-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6026 Fix --help=recursive with multiple AC_CONFIG_SUBDIRS.
6027 * lib/autoconf/general.m4 (_AC_INIT_HELP): If, for recursive help
6028 mode, we change to the source directory, also set $ac_pwd so we
6029 do not go back to the build tree for the next config subdir.
6030 * tests/torture.at (Deep Package): Extend test to contain two
6031 config subdirs on the top level.
6033 Fix parallel `maintainer-check'.
6034 * Makefile.am (maintainer-check-tests): Depend on `all'.
6035 Use `$(MAKE) $(AM_MAKEFLAGS)' instead of plain `make'.
6036 * tests/Makefile.am (maintainer-check-c++, maintainer-check-posix):
6038 (maintainer-check): Serialize the testsuite runs.

6062 2008-01-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6064 * tests/Makefile.am (noinst_SCRIPTS): Renamed from
6065 check_SCRIPTS. Building the wrappers for `all' allows help2man
6066 to use them for the manpages.
6067 Report by Benoit Sigoure.
6069 * bin/autoreconf.in: Discard stderr for $autoconf/$aclocal --help.
6071 2007-12-16 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6073 Fix some write failure cases in Autotest.

6080 2007-12-12 Eric Blake <ebb9@byu.net>
6082 Fix thinko in earlier patch - m4_join isn't defined yet.
6083 * lib/m4sugar/m4sugar.m4 (m4_expansion_stack_push, _m4_defun_pro)
6084 (_m4_defun_pro_outer, _m4_defun_epi, _m4_defun_epi_outer)
6085 (m4_require): Use m4_do, not m4_join.
6087 Fix some whitespace tests on cygwin.
6088 * tests/tools.at (autom4te and whitespace in file names): Restore
6089 font-lock. Create $TMPDIR before it might be used.
6091 Fix spurious testsuite failure with M4 1.4.11.
6092 * tests/local.at (AT_CHECK_M4): Cater to new m4 error message.
6094 Optimize AC_REQUIRE.
6095 * lib/m4sugar/m4sugar.m4 (m4_expansion_stack_push, _m4_defun_pro)
6096 (_m4_defun_pro_outer, _m4_defun_epi, _m4_defun_epi_outer)
6097 (m4_require): Avoid extra macro calls.
6099 2007-12-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6101 * tests/torture.at (srcdir): Fix quoting.
6103 Do not pass top_srcdir to configure scripts in testsuite.
6104 * tests/autotest.at (srcdir propagation): Copy install-sh to
6106 (my only test): Drop setting of `top_srcdir'.
6107 * tests/base.at (Input/Output): Likewise.
6108 * tests/local.at (AT_CONFIGURE_AC): Copy install-sh,
6109 config.guess, and config.sub to test source tree.
6110 Drop AC_CONFIG_AUX_DIR setting.
6111 (AT_CHECK_CONFIGURE): Drop setting of `top_srcdir'.
6112 * tests/torture.at (Substitute a 2000-byte string): Drop
6113 AC_CONFIG_AUX_DIR setting, copy install-sh to test source tree.
6114 (Substitute a newline, datarootdir workaround): Likewise.
6115 (Define a newline): Adjust for linenumber changes in configure.ac.
6116 * tests/foreign.at (Libtool): Adjust comment to reflect changes.
6118 * tests/semantics.at (AC_PATH_PROGS_FEATURE_CHECK): Skip test
6119 if `pwd` contains whitespace.
6121 Quote $abs_top_srcdir in tests.
6122 * tests/local.at (AT_CHECK_PERL_SYNTAX): Likewise.
6123 * tests/tools.at (Syntax of the shell scripts): Likewise.
6125 * tests/m4sh.at (LINENO): Quote $0.
6127 Fix testsuite program wrapper for whitespace in `pwd`.
6128 The problem here is that the usual mantra is that command
6129 variables can contain arguments, thus we cannot just escape
6130 $AUTOCONF, $AUTOM4TE etc. The compromise is to put the
6131 $top_builddir/tests directory early in $PATH, so that the
6132 wrappers are found by their plain name.
6133 * tests/wrapper.as: Put $testdir early in $PATH.
6134 (AUTOCONF, AUTOHEADER, AUTOM4TE): Set to plain command names.
6136 Proper config.status --file/--header and $srcdir escaping.
6137 * lib/autoconf/status.m4 (_AC_OUTPUT_MAIN_LOOP): Quote special
6138 characters in $ac_file_inputs.
6139 (_AC_OUTPUT_FILE, _AC_OUTPUT_HEADER): eval $ac_file_inputs
6141 * tests/torture.at (datarootdir workaround): Adjust.
6142 (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS): Extend test.
6144 Fix Autotest for whitespace in `pwd`.
6145 * lib/autotest/general.m4 (AT_INIT)
6146 <at_func_create_debugging_script, Driver Loop>:
6147 Quote $at_group_dir.
6148 * tests/autotest.at (whitespace in absolute testdir): New test.
6150 * lib/autom4te.in: Quote @datadir@.
6152 Proper file name escaping in Autoconf programs and Perl modules.
6153 This includes escaping of characters special to the shell
6154 as well as special to Perl, e.g., leading `<' or `>'.
6155 For example, when $file starts with `>', `open ">$file"'
6156 wrongly tries to append to a different file.
6157 * bin/autoconf.as: Fix quoting for autom4te options.
6158 * lib/Autom4te/General.pm (shell_quote): New function, taken
6159 from coreutils, written by Jim Meyering.
6161 * bin/autom4te.in (files_to_options, handle_m4): Use shell_quote
6163 * bin/autoreconf.in (parse_args): Likewise.
6164 * bin/autoscan.in (main): Likewise.
6165 * bin/autoupdate.in (main): Likewise.
6166 * bin/autoheader.in: Likewise, fixing old insufficient escaping.
6167 * bin/ifnames.in: Likewise, XFile usage fixes.
6168 * tests/tools.at (autom4te and whitespace in file names): Extend
6169 test. Test twice, with special characters allowed on w32, and the
6170 rest. Test leading and trailing whitespace, for `open_quote'.
6171 (autotools and whitespace in file names): New, analogous test.
6172 Reported by Paul Eggert and Benoit Sigoure, additional suggestions
6173 by Russ Allbery and Eric Blake.
6176 * lib/Autom4te/Channels.pm, lib/Autom4te/Configure_ac.pm,
6177 lib/Autom4te/Struct.pm, lib/Autom4te/XFile.pm: Likewise.
6178 * lib/Autom4te/FileUtils.pm (open_quote): New function.
6179 (update_file, contents): Use it.
6181 * Makefile.am (autom4te-update): Rewrite for git.
6183 2007-12-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6185 * doc/autoconf.texi (autom4te Invocation, Autom4te Cache): Fix typos.
6187 Fix copyright years.
6188 * Makefile.am, doc/install.texi, lib/autoconf/fortran.m4,
6189 lib/autoconf/lang.m4, lib/freeze.mk: Likewise.
6191 2007-12-04 Eric Blake <ebb9@byu.net>
6193 Manually resync with gnulib, since 'make cvs-update' no longer works.
6194 * build-aux/config.guess: New upstream version.
6195 * build-aux/config.sub: Likewise.
6197 When using older automake, don't downgrade build-aux/texinfo.tex.
6198 * configure.ac (AM_INIT_AUTOMAKE): Add no-texinfo.tex option.
6199 * doc/Makefile.am (TEXINFO_TEX): Add.
6201 2007-11-27 Paul Eggert <eggert@cs.ucla.edu>
6203 Fix AC_C_BIGENDIAN bug caused by new awk method of substitution.
6204 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Don't comment out the
6205 #undef as this runs afoul of our new way of creating config.h.
6206 Problem reported by Jim Meyering in
6207 <http://lists.gnu.org/archive/html/autoconf-patches/2007-11/msg00164.html>.
6209 2007-11-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6211 Fix autom4te for unusual characters in input file names.
6212 * bin/autom4te.in (files_to_options): Quote active characters
6214 * tests/tools.at (autom4te and white space in file names):
6217 * doc/autoconf.texi (Limitations of Usual Tools) <awk>:
6218 Document that Tru64 awk always splits $0.
6220 2007-11-24 Stepan Kasal <kasal@ucw.cz>
6222 * lib/autotest/general.m4 (AT_INIT): Do not extract the
6223 `#AT_STOP_...' line at the end of each test.
6225 2007-11-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6227 * lib/autotest/general.m4 (AT_INIT): For awk line number
6228 extraction script, ensure `$at_group' has a defined value
6229 even for the empty set, and properly quote its usage inside
6232 2007-11-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6234 * doc/autoconf.texi (Shell Functions): New chapter. Document
6235 IRIX sh $0 issue in functions, move content from ...
6236 (Portable Shell): ... here.
6237 (Shell Script Compiler): Note that shell functions are not
6238 totally unportable any more.
6240 2007-11-22 Stepan Kasal <kasal@ucw.cz>
6241 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6243 * lib/autotest/general.m4 (AT_INIT): Exit awk script after
6244 extracting the line numbers of the last needed test.
6246 2007-11-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6248 * lib/autotest/general.m4 (AT_INIT) <at_func_create_debugging_script>:
6251 2007-11-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6253 Fix IRIX testsuite debugging failures: $0 in functions.
6254 * lib/autotest/general.m4 (AT_INIT) <at_func_create_debugging_script>:
6255 Do not use $0 inside a function, as IRIX sh will set that to the
6256 function name rather than the script invocation name.
6258 2007-11-19 Paolo Bonzini <bonzini@gnu.org>
6259 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6261 * lib/autotest/general.m4 (at_func_test): Use cached line numbers
6262 to extract test scripts.
6263 (AT_INIT): Extract and cache test script line numbers.
6265 2007-11-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6267 * lib/autotest/general.m4: Revert 2007-11-15 patch and
6268 subsequent fixups; the awk -> here-document conversion trashes
6269 performance too much with AIX sh.
6271 2007-11-18 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6273 * tests/local.at: Do not test m4, perl with AT_TESTED.
6275 Diagnose and guard against write errors dealing with config.status.
6276 The general idea is this: all write failures from `configure'
6277 writing `config.status' are indicated by $ac_write_error, which
6278 is only checked at the end. This is safe because config.status
6279 code is not executed before the file is complete. Other write
6280 failures, be they inside config.status, or in sub shell/awk
6281 scripts spawned from configure or config.status, typically need
6282 earlier checking, as their results are used right afterwards.
6283 * lib/autoconf/status.m4 (AC_OUTPUT): Initialize `ac_write_fail'
6284 before writing config.status, check afterwards.
6285 (_AC_OUTPUT_FILES_PREPARE, _AC_OUTPUT_FILE)
6286 (_AC_OUTPUT_HEADERS_PREPARE,_AC_OUTPUT_CONFIG_STATUS):
6287 Set `ac_write_error' for write failures to config.status. Barf
6288 upon write failures to temporary files.
6289 Adjust note about closing and reopening the here-document.
6290 (_AC_OUTPUT_HEADER, _AC_OUTPUT_LINK, _AC_OUTPUT_COMMAND)
6291 (_AC_OUTPUT_MAIN_LOOP): Likewise, adjust note about closing and
6292 reopening the here-document.
6293 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
6294 Ensure `ac_write_error' does not escape into config.status.
6295 Also, add a couple of code paths not yet exercised in the test
6296 suite: a config file with input from stdin, and a config header
6298 Suggestion for catching write errors by Bruno Haible.
6300 2007-11-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6302 Avoid error with Tru64 awk and testsuite lines with many words.
6303 * lib/autotest/general.m4 (AT_INIT): In the awk script that
6304 reads the testsuite, set the field separator to an unusual value,
6305 in order to not run over the limit of 199 fields. Tru64 4.0D awk
6306 even splits the input if $i, i>0, was never accessed in the script.
6308 Revert 2007-10-17 change.
6309 * TODO: Multiline args in config files and headers mean something
6310 different and are not fixed, see
6311 <http://lists.gnu.org/archive/html/autoconf-patches/2007-05/msg00017.html>
6312 Report by Stepan Kasal.
6314 * doc/autoconf.texi (Generic Programs): Fix typo.
6316 2007-11-16 Stepan Kasal <kasal@ucw.cz>
6318 AC_*_TOOL does not canonicalize the prefix
6319 * doc/autoconf.texi (Generic Programs): Do not say that
6320 the *_TOOL macros canonicalize, they simply use the `host_alias'.
6322 2007-11-16 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6324 Diagnose write errors in config.status instantiations.
6325 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE)
6326 (_AC_OUTPUT_HEADER, _AC_OUTPUT_MAIN_LOOP): Bail out
6328 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
6329 Extend test to also check for some write error failures, using...
6330 <AT_CHECK_CONFIG_CREATION_NOWRITE>: ...this new macro.
6331 Report by Bruno Haible.
6334 * lib/autotest/general.m4 (AT_INIT) <at_func_log_failure>: Fix

6340 Add witness macro for @top_build_prefix@ substitution.
6341 * lib/autoconf/status.m4 (_AC_HAVE_TOP_BUILD_PREFIX): New macro.
6342 (_AC_OUTPUT_FILE): Mention it here.
6344 2007-11-15 Paolo Bonzini <bonzini@gnu.org>
6345 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6347 * lib/autotest/general.m4 (at_func_test): Remove.
6348 (AT_INIT): Pre-extract test groups into separate files.
6349 (AT_CLEANUP): Source pre-extracted file instead of calling at_func_test.
6350 Remove at-test-source files together with the $at_group_dir.
6351 * tests/autotest.at (Long test source lines): New test.
6353 2007-11-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6355 Shell functions and variables may share a namespace.
6356 * doc/autoconf.texi (Portable Shell): Mention Solaris sh
6359 2007-11-14 Paul Eggert <eggert@cs.ucla.edu>
6361 * lib/autoconf/types.m4 (_AC_TYPE_LONG_LONG_SNIPPET): Make comment match
6364 2007-11-14 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6366 * lib/autoconf/status.m4: Fix a couple of comment typos.
6368 * lib/m4sugar/m4sh.m4 (AS_TMPDIR): Use $as_me, not $me.
6370 2007-11-13 Jim Meyering <meyering@redhat.com>
6372 Clean up the rule to create "expr".
6373 * tests/Makefile.am (expr): Don't redirect directly to target.
6374 Redirect just once, not for each echo statement.
6375 Use $@, not literal "expr".
6377 2007-11-13 Paul Eggert <eggert@cs.ucla.edu>
6379 Don't worry about preprocessor when testing long long.
6380 See: http://lists.gnu.org/archive/html/bug-gnulib/2007-11/msg00075.html
6381 * doc/autoconf.texi (Preprocessor Arithmetic): New section.
6382 (AC_TYPE_LONG_LONG_INT, AC_TYPE_UNSIGNED_LONG_LONG_INT):
6383 These no longer check for preprocessor flaws.
6384 * lib/autoconf/types.m4 (_AC_TYPE_LONG_LONG_SNIPPET):
6385 Do not check for preprocessor flaws.
6387 2007-11-13 Jim Meyering <meyering@redhat.com>
6389 Adapt dependencies, now that a version change doesn't modify configure.ac
6390 * GNUmakefile: Remove "make clean" kludge.
6391 * lib/m4sugar/Makefile.am (version.m4): Depend on Makefile, not
6393 Don't redirect directly to target.
6394 Use $@, not literal "version.m4".
6396 2007-11-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6398 * doc/autoconf.texi (Making testsuite Scripts): Document
6399 ":;{" shorthand as in previous patch.
6401 2007-11-12 Paul Eggert <eggert@cs.ucla.edu>

6407 Use ":;{" shorthand.
6408 * tests/Makefile.am ($(srcdir)/package.m4): Likewise.
6410 2007-11-12 Jim Meyering <meyering@redhat.com>
6412 Add more non-srcdir build support.
6413 * GNUmakefile (dummy): Split a long line.
6414 Add -v option to autoreconf invocation.
6416 Remove the autoreconf-provided INSTALL, so that we regenerate it.
6417 * GNUmakefile (dummy): Remove INSTALL.
6419 Remove racy commands to build scripts in bin/ and tests/.
6420 * man/Makefile.am (.x.1): Now that scripts in bin/ and tests/
6421 are guaranteed to be built, remove the rules that tried to build
6422 them. Before, with a parallel build, these rules could lead to
6423 two processes writing tests/wrapper.in concurrently.
6425 Build in man/ only *after* building in bin/ and tests/.
6426 * Makefile.am (SUBDIRS): The man-page-creation process runs $(MAKE)
6427 in both bin/ and tests/.
6429 Accommodate non-srcdir build-from-checkout.
6430 * build-aux/git-version-gen: Require an additional parameter: $srcdir.
6431 Use git's --git-dir=$srcdir/.git option.
6432 Add quotes, in case tarball_version_file contains shell meta-characters.
6433 * GNUmakefile (_curr-ver): Pass $(srcdir) to git-version-gen.
6434 * configure.ac: Pass "." to git-version-gen.
6436 Avoid spurious test failures due to version skew.
6437 * GNUmakefile (dummy): Run $(MAKE) clean after autoreconf -i.

6469 writable again for the `stderr' file, and ignore errors due to
6470 the attempt to write configure.lineno.

6476 * tests/Makefile.am (package.m4): Adjust target.
6477 Don't redirect directly to $@.
6478 (CLEANFILES): Add package.m4.
6479 ($(TESTSUITE)): Depend on just-built package.m4, not the one
6481 When running $(AUTOTEST), search "." before searching $(srcdir).
6483 Avoid a race condition that would make parallel "distclean" fail.
6484 * tests/Makefile.am (distclean-generic): Replace the default,
6485 automake-provided rule with an identical one, but with an additional
6486 dependency on distclean-local. Simply adding the dependency would
6487 cause automake not to emit the rule at all.
6488 * BUGS: Building with -jN works, now.
6490 Distribute git-version-gen.
6491 * Makefile.am (EXTRA_DIST): Add build-aux/git-version-gen,
6492 since GNUmakefile is distributed, and requires it for dist* rules.
6494 Remove two more generated files from version control.
6495 * INSTALL: Remove generated file.
6496 * lib/autoscan/autoscan.list: Remove generated file.
6498 2007-11-09 Paul Eggert <eggert@cs.ucla.edu>
6500 * GNUmakefile (PATH): Remove stray apostrophes; they become
6501 part of PATH, which isn't wanted here.
6503 2007-11-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6505 New config files output variable `top_build_prefix'.
6506 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Substitute
6508 * doc/autoconf.texi (Preset Output Variables): Document it.
6510 Report by Bob Friesenhahn.
6512 Avoid expr for arithmetic evaluation if the shell accepts $((...)).
6513 * lib/autotest/general.m4 (AT_INIT) <at_func_arith>: New
6514 function, to parametrize arithmetic with expr vs. the shell.
6515 Use it where possible.
6516 Suggestion by Benoit Sigoure.
6518 2007-11-03 Benoit Sigoure <tsuna@lrde.epita.fr>
6520 Adjust the documentation of autotest WRT atlocal.
6521 * doc/autoconf.texi (Making testsuite Scripts): It is not necessary,
6522 when using Automake, to write a rule to produce atlocal, since it's
6523 an AC_CONFIG_FILES. Mention that atlocal.in needs to be
6524 distributed, not atconfig.in.
6526 2007-11-04 Eric Blake <ebb9@byu.net>
6528 Update list information.
6529 * README: Mention new autoconf-commit list.
6530 * doc/autoconf.texi (Introduction): Mention autoconf-commit list.
6532 2007-11-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6534 * lib/autoconf/functions.m4 (_AC_FUNC_MALLOC_IF): Fix comment typo.
6536 * lib/m4sugar/Makefile.am (version.m4): Another bash bug workaround.
6538 * build-aux/.gitignore: Ignore mkinstalldirs.
6540 * doc/autoconf.texi (autoreconf Invocation): Fix an underfull line.
6542 2007-11-03 Jim Meyering <meyering@redhat.com>
6544 s/-/./ in snapshot version string: 2.61a-256-8b556 -> 2.61a.256-8b556
6545 * build-aux/git-version-gen: This syncs from coreutils.
6547 Adjust the build procedure so "make check" works reliably.
6548 * README-hacking: Include an extra step between "make" and
6549 "make check" to ensure that the latter passes.
6551 Use just-built tools, when possible.
6552 * GNUmakefile (PATH): Set and export here, ...
6553 (dummy): ... rather than here.
6555 2007-11-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6556 and Andreas Schwab <schwab@suse.de>
6558 * tests/Makefile.am ($(srcdir)/package.m4): Work around bash
6561 2007-11-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6563 * configure.ac (AC_PREREQ): Require version 2.60, for
6564 AC_PROG_SED, AC_PROG_GREP.
6566 2007-11-02 Benoit Sigoure <tsuna@lrde.epita.fr>
6567 and Jim Meyering <meyering@redhat.com>
6568 and Andreas Schwab <schwab@suse.de>
6569 and Eric Blake <ebb9@byu.net>
6571 Document a bug in GNU Bash with compound commands and redirections.
6572 * doc/autoconf.texi (Limitations of Builtins): Mention that GNU
6573 Bash doesn't properly set $? when `{ ... } >/bad' fails, and give
6576 2007-11-03 Eric Blake <ebb9@byu.net>
6578 Support m4 1.4.5 in testsuite.
6579 * tests/torture.at (Define a newline): Exclude line numbers in
6581 Reported by Ralf Wildenhues.
6583 2007-11-03 Jim Meyering <meyering@redhat.com>
6585 Remove automake-provided files from version control.
6586 * build-aux/elisp-comp: Remove file.
6587 * build-aux/install-sh: Remove file.
6588 * build-aux/missing: Remove file.
6589 * build-aux/mdate-sh: Remove file.
6590 * build-aux/.gitignore: New file.
6591 Suggestion from Ralf Wildenhues.
6593 2007-11-03 Eric Blake <ebb9@byu.net>
6595 Adjust version comparison to account for git snapshot numbers.
6596 * lib/m4sugar/m4sugar.m4 (_m4_version_unletter): Also treat - as a
6597 component separator.
6598 * doc/autoconf.texi (Number processing Macros)
6599 <m4_version_compare>: Document this change.
6600 * tests/m4sugar.at (m4@&t@_version_compare): Test it.
6602 2007-10-30 Bruno Haible <bruno@clisp.org>
6604 * lib/autoconf/types.m4 (_AC_TYPE_LONG_LONG_SNIPPET): New macro,
6605 extracted from AC_TYPE_LONG_LONG_INT and AC_TYPE_UNSIGNED_LONG_LONG_INT.
6606 (AC_TYPE_LONG_LONG_INT, AC_TYPE_UNSIGNED_LONG_LONG_INT): Use it.
6607 Fixes problem with Sun C 5.[0-8] in 32-bit mode, reported in
6608 <http://lists.gnu.org/archive/html/autoconf-patches/2007-10/msg00210.html>
6609 Suggested by Paul Eggert.
6611 2007-10-28 Jim Meyering <meyering@redhat.com>
6613 * README-hacking: Autoconf, Automake, and Perl are required to build.
6614 List Gzip and Tar separately. Suggested by Ralf Wildenhues.
6616 2007-10-28 Jim Meyering <meyering@redhat.com>
6618 README-hacking: Recommend running autoreconf -vi.
6619 * GNUmakefile (dummy): Use autoreconf -i, with appropriate PATH,
6620 so that we use just-built tools when they're available.
6621 Suggestions from Ralf Wildenhues.
6623 2007-10-28 Jim Meyering <meyering@redhat.com>
6625 Make inter-release --version output more useful.
6627 Now, each unofficial build has a version "number" like 2.61a-19-58dd,
6628 which indicates that it is built using the 19th change set
6629 (in _some_ repository) following the "v2.61a" tag, and that 58dd
6630 is a prefix of the commit SHA1.
6631 * build-aux/git-version-gen: New file.
6632 * configure.ac: Run it to set the version.
6633 (AM_INIT_AUTOMAKE): Don't check NEWS here.
6634 * Makefile.am (dist-hook): Arrange so that .version appears only
6635 in distribution tarballs, never in a checked-out repository.
6636 * .gitignore: Add .version here, too. Just in case.
6637 * tests/Makefile.am ($(srcdir)/package.m4): Depend on Makefile,
6638 not configure.ac, now that the version number changes automatically.
6640 Ensure that $(VERSION) is up to date for dist-related targets.
6641 * GNUmakefile: Arrange to rerun autoconf, if the version reported by
6642 git-version-gen doesn't match $(VERSION), but only for dist targets.
6644 2007-10-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6646 Fix `Deep Package' failure with a configure script early in PATH
6647 * tests/torture.at (Deep Package): Add `.' early in PATH.
6648 Report by Jim Meyering.
6650 2007-10-27 Jim Meyering <meyering@redhat.com>

6672 2007-10-22 Paul Eggert <eggert@cs.ucla.edu>
6673 and Eric Blake <ebb9@byu.net>
6675 * lib/autoconf/c.m4 (AC_C_RESTRICT): Work around Sun C++ compatibility
6676 problem reported by Bruno Haible in
6677 <http://lists.gnu.org/archive/html/bug-autoconf/2007-10/msg00027.html>.
6679 2007-10-22 Eric Blake <ebb9@byu.net>
6681 * doc/autoconf.texi (Particular Types): Mention bug in HP-UX 11.00
6684 2007-10-22 Paul Eggert <eggert@cs.ucla.edu>
6686 Don't check for bug in HP-UX 11.00 cpp.
6687 * lib/autoconf/types.m4 (AC_TYPE_UNSIGNED_LONG_LONG_INT):
6688 Use -1ull rather than -1u, since that causes problems with gnulib; see
6689 <http://lists.gnu.org/archive/html/bug-gnulib/2007-10/msg00329.html>.

6707 escaping of backslash in here-documents.
6709 Fix `Deep Package' test failure on FreeBSD.
6710 * tests/torture.at (Deep Package): Do not add `.' to $PATH
6711 unnecessarily. Do not try running `/bin/sh configure' with a
6712 configure script to be found in $PATH, if the shell does not do
6713 this resolution. Fixes test failure on FreeBSD.
6715 Fix config header generation with AIX awk.
6716 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS_PREPARE): In awk
6717 script, use helper array D_is_set, as `" 0"' does not evaluate
6718 to true for AIX awk.

6759 array of banner text from a special diversion.
6760 <PARSE_ARGS_END>: No longer need awk to find banners.
6761 <TESTS>: Banners are no longer processed by main driver loop, so
6762 we no longer need case statement.

6861 use $as_myself, not $0.

7939 Document the restrictions on AC_CHECK_ALIGNOF's type argument.
7940 * lib/autoconf/types.m4 (_AC_CHECK_TYPE_NEW):
7941 For C, just try sizeof (TYPE) and sizeof ((TYPE)); if the former
7942 works but the latter doesn't, then it's a valid type.
7943 This lets people use function types and so forth.
7944 For C++ there doesn't seem to be a simple solution, so leave it alone.
7945 (AC_CHECK_SIZEOF): Allow argument to be a variable.
7946 (AC_CHECK_SIZEOF, AC_CHECK_ALIGNOF): Don't bother to invoke

8142 2007-01-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8144 * lib/autoconf/programs.m4 (AC_PROG_SED): When closing a pipe
8145 early on the reader side, drop stderr of the input to avoid
8146 `broken pipe' error output; this may happen even with shell
8147 builtin `echo' of some bash versions. Reports by Ian Macdonald
8148 <iamacdo@telkomsa.net> and Sam Sexton <Sam.Sexton@reuters.com>.
8150 2007-01-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

8163 http://lists.gnu.org/archive/html/autoconf-patches/2007-01/msg00077.html
8164 * doc/autoconf.texi (Signed Overflow Examples): Give more
8165 discussion about the allow_superuser_privileges example,
8166 and change it a bit to make things clearer.
8167 (Optimization and Wraparound): Clarify whether the compiler
8168 will generate an infinite loop for the example derived from
8169 Autoconf's mktime test.
8170 (Signed Overflow Advice): Say that -ftrapv is meant for debugging.
8171 Also, clarify unsigned multiplication overflow.
8173 2007-01-04 Eric Blake <ebb9@byu.net>
8175 * bin/Makefile.am (RELEASE_YEAR): New macro.
8176 (edit): Use it to supply correct copyright year to scripts.
8177 * bin/autoconf.as (version): Use it.
8178 * bin/autoheader.in ($version): Likewise.
8179 * bin/autom4te.in ($version): Likewise.
8180 * bin/autoreconf.in ($version): Likewise.

8185 2007-01-02 Paul Eggert <eggert@cs.ucla.edu>
8187 * doc/autoconf.texi (Integer Overflow): Revised based on today's
8188 feedback. The most important changes document what happens when
8189 you convert an out-of-range value to a signed integer type, and
8190 say that (sum < a) != (b < 0) reliably detects overflow when sum =
8193 * doc/autoconf.texi (Integer Overflow): Greatly expand and
8194 rewrite, taking notions from the recent discussion on the gcc and
8195 autoconf mailing lists; please see
8196 http://lists.gnu.org/archive/html/autoconf-patches/2006-12/msg00091.html
8197 and follow the many links.
8198 (Integer Overflow Basics, Signed Overflow Examples):
8199 (Optimization and Wraparound, Signed Overflow Advice):
8200 (Signed Integer Division): New sections.
8202 2006-12-28 Steven G. Johnson <stevenj@alum.mit.edu>
8204 * lib/autoconf/general.m4 (AC_DEFINE_TRACE): Don't include
8205 preprocessor macro arguments in traced name.
8206 * doc/autoconf.texi (Defining symbols): Document longstanding
8207 support for AC_DEFINE-ing macros with arguments, and document
8208 behavior when the same variable has multiple AC_DEFINEs.
8209 * lib/autoconf/fortran.m4 (_AC_FC_WRAPPERS): Revert to the
8210 old implementation which AC_DEFINEs the FC_FUNC and FC_FUNC_
8211 macros directly, giving much shorter and simpler code.
8213 2006-12-28 Malcolm Purvis <malcolmp@xemacs.org> (trivial change)
8215 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Insert a
8216 space before "$ac_configure_args" to prevent a 'config.status
8217 --recheck' failure if ac_configure_args doesn't contain a leading
8218 space. This works around a problem with the XEmacs configure.ac,
8219 which uses the (undocumented) ac_configure_args variable
8220 inconsistently with Autoconf.
8222 2006-12-22 Paul Eggert <eggert@cs.ucla.edu>
8224 * lib/autoconf/functions.m4 (AC_FUNC_MKTIME):
8225 Include <limits.h>, and use its INT_MAX to rewrite the
8226 j loop so that it does not overflow 'int'. Problem reported by
8228 <http://lists.gnu.org/archive/html/bug-gnulib/2006-12/msg00084.html>.
8229 Play it safe by shifting left by 1 rather than multiplying by 2,
8230 as GCC is less likely to optimize this away when the value
8231 is signed (when it assumes overflow leads to undefined behavior).
8232 Also, don't assume time_t uses two's complement.
8234 2006-12-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8236 * tests/torture.at (Substitute a 2000-byte string): Avoid using
8237 a 10kB long (multi-line) string literal, OpenServer 5.0.7 ksh
8238 dumps core on it. Report by Tim Rice.
8240 2006-12-18 Steven G. Johnson <stevenj@alum.mit.edu>
8242 * lib/autoconf/general.m4 (AC_ARG_ENABLE): Print help about
8243 --disable-option-checking to --help output even when
8244 AC_PRESERVE_HELP_ORDER is not used.
8245 (_AC_INIT_PARSE_ENABLE2): Print warnings using actual --enable or
8246 --with argument, rather than argument with [-.] replaced by
8248 * NEWS: Fix typo in previous change; the news was in the
8251 2006-12-18 Paul Eggert <eggert@cs.ucla.edu>
8253 * NEWS: Warnings are now generated by default for unknown
8254 --enable-* and --with-* options.
8255 * doc/autoconf.texi (Option Checking): Renamed from
8256 (Configure Option Checking). Tighten up the wording a bit.
8257 (External Software, Package Options): Cross-reference to Option
8258 Checking, and use this to shorten our section.
8259 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Prefer test -n
8260 "$x" to test "x$foo" != x.
8261 * lib/autoconf/status.m4 (AC_OUTPUT): Likewise.
8262 Don't warn if $enable_option_checking is "no".
8263 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Initialize
8264 ac_unrecognized_opts to the empty string.
8265 Don't echo the unrecognized opts, as this might mishandle
8266 backslashes or leading -.
8267 (AC_PRESERVE_HELP_ORDER): Put the --disable-option-checking
8268 usage next to the other --disable-FEATURE options in the
8271 2006-12-18 Steven G. Johnson <stevenj@alum.mit.edu>
8273 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS, _AC_INIT_PARSE_ARGS):
8274 (_AC_INIT_PARSE_ENABLE2, _AC_INIT_HELP, _AC_ENABLE_IF):
8275 Print warning for unrecognized --with and --enable options
8276 (AC_DISABLE_OPTION_CHECKING): New macro to disable warnings.
8277 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS, _AC_OUTPUT_SUBDIRS):
8278 Disable option checking when subdirs are configured.
8279 (AC_OUTPUT): If warnings are enabled, print warning about
8280 unrecognized --with and --enable options at the end of
8281 the configure output (as well as at the beginning).
8282 * doc/autoconf.texi (Option Checking): New node.
8283 Document new option warning functionality.
8285 2006-12-16 Eric Blake <ebb9@byu.net>
8287 * configure.ac (AC_INIT): Bump version, since 2.61a is released.
8288 * NEWS: Start news for current version.
8290 2006-12-15 Paul Eggert <eggert@cs.ucla.edu>
8292 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT):
8293 Define HAVE_GETMNTENT to 1, not to the empty string.
8294 Problem originally reported by Jochen Friedrich in
8295 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=403243>.
8297 This change prompted by a problem report by Andrey Simonenko in
8298 <http://lists.gnu.org/archive/html/bug-autoconf/2006-12/msg00026.html>.
8299 * doc/autoconf.texi (Defining Symbols): AC_DEFINE works for
8300 object-like macros only, in the traditional portable character
8302 * lib/autoconf/general.m4 (AC_DEFINE_TRACE_LITERAL):
8303 Warn about attempts to define things that are not identifiers.
8304 * lib/autoconf/fortran.m4 (_AC_FC_WRAPPERS): Rewrite to avoid
8305 awful hack that AC_DEFINEd macro names containing parentheses.
8307 2006-12-12 Paul Eggert <eggert@cs.ucla.edu>
8309 * doc/autoconf.texi: Undo some of the 2006-12-10 change. It was
8310 too drastic, even if Texinfo in theory requires it for info mode.
8312 (config.status Invocation): Renamed back from Recreating a
8314 (Obsolete config.status Use): Renamed back from Obsolete Recreation.
8315 (Autoconf 2.13): Renamed back from 20th-century Autoconf 2.
8317 2006-12-11 Paul Eggert <eggert@cs.ucla.edu>
8319 * NEWS: Version 2.61a.
8321 2006-12-11 Paul Eggert <eggert@cs.ucla.edu>
8322 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8324 * NEWS: Document changes with echo and printf, and the lack
8325 of limits on the total size of multi-line values of substituted
8326 variables, and the AC_FUNC_FSEEKO fix.
8328 2006-12-10 Paul Eggert <eggert@cs.ucla.edu>
8330 * doc/autoconf.texi (Writing Autoconf Input): Renamed from
8331 Writing configure.ac.
8332 (Autoconf Input Layout): Renamed from configure.ac Layout.
8333 (Recreating a Configuration): Renamed from config.status Invocation.
8334 (Obsolete Recreation): Renamed from Obsolete config.status Use.
8335 (acconfig Header): Renamed from acconfig.h.
8336 (20th-century Autoconf 2): Renamed from Autoconf 2.13.
8337 (Writing Testsuites): Renamed from Writing testsuite.at.
8338 (Autom4te Cache): Renamed from autom4te.cache.
8340 * BUGS: Remove mention of VPATH problem, since it's now documented
8341 not to be a bug in the Autoconf build procedure itself, but rather
8342 a problem with the proprietary `make' programs.
8344 * doc/autoconf.texi (Build Directories): Add a cross reference
8347 * build-aux/config.guess, build-aux/config.sub, build-aux/texinfo.tex:
8348 * doc/standards.texi: Sync from gnulib.
8350 * man/autoconf.1, man/autoheader.1, man/autom4te.1, man/autoreconf.1:
8351 * man/autoscan.1, man/autoupdate.1, man/config.guess.1:
8352 * man/config.sub.1, man/ifnames.1: Remove from CVS, since they're
8353 generated automatically.
8355 2006-12-06 Paul Eggert <eggert@cs.ucla.edu>
8357 * lib/autoconf/c.m4 (_AC_PROG_CC_C89): Also try -xc99=all, for Sun
8358 C 5.8 on Solaris 10. Using -xc99=all rather than -xc99 bypasses
8359 the buggy -xc99 option of Forte Developer 7 C on Solaris 9.
8361 2006-12-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8363 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Drop the
8364 `CEOF$ac_eof' special marker, the awk script cannot contain a
8365 line matching `^CEOF', so this is not needed any more.
8366 * tests/torture.at (Substitute a newline): Expose the `%!_!# '
8367 special marker in the test.
8369 2006-12-06 Stepan Kasal <kasal@ucw.cz>
8371 * tests/tools.at (autom4te preselections): Use `find -newer';
8372 remove one of the sleeps.
8374 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE): Make it
8375 more readable, using ...
8376 (_AC_INIT_PARSE_ENABLE2): ... this new helper macro.
8378 * doc/autoconf.texi (autoheader Invocation): Do not double-
8379 quote the parameter of `AH_BOTTOM' in the example.
8381 2006-12-05 Stepan Kasal <kasal@ucw.cz>
8383 * doc/autoconf.texi (Configuration Headers): Remove the
8384 example with multiple input files.
8385 (autoheader Invocation): Encourage `AH_BOTTOM', discouraging
8386 multiple input files.
8388 2006-12-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8390 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): When
8391 creating the awk substitution script, handle one input line at a
8392 time, so that the maximum length of a substituted (multi-line)
8393 value is not limited by the size of the sed pattern space.
8394 The trade-off is a slightly repetitive sed script.
8395 * doc/autoconf.texi (Limitations of Usual Tools): Branch labels
8396 can only have up to 7 characters, due to Solaris 10 /bin/sed.
8397 * tests/torture.at (Substitute a 2000-byte string): Increase the
8398 test with several long lines, they should not be caught by sed
8401 * tests/tools.at (autom4te preselections): New test, to flag
8402 entries missing from autom4te.cfg.
8403 Report by David Byron <dbyron@hheld.com>.
8405 * tests/torture.at (Substitute a 2000-byte string): Actually use
8406 AC_PROG_AWK, so the last change works as intended.
8407 (Substitute and define special characters): Likewise.
8408 (Substitute a newline): Likewise.
8410 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Use `$AWK'
8411 instead of `awk' consistently.
8412 (_AC_OUTPUT_CONFIG_STATUS): Initialize $AWK.
8413 * tests/torture.at (Torturing config.status): Test both the
8414 result of AC_PROG_AWK and plain awk.
8415 (Substitute a 2000-byte string): Likewise.
8416 (Substitute and define special characters): Likewise.
8417 (Substitute a newline): Likewise.
8419 2006-12-04 Paul Eggert <eggert@cs.ucla.edu>
8421 * lib/autoconf/functions.m4 (AC_FUNC_FSEEKO): Check that fseeko
8422 can be assigned to a function pointer. Problem reported by
8423 Peter Palfrader in <http://bugs.debian.org/401377>. Based on
8424 part of a patch by Ralf Wildenhues in that same bug report.
8426 2006-12-01 Paul Eggert <eggert@cs.ucla.edu>
8428 * tests/mktests.sh (ac_exclude_list): Exclude AC_FUNC_SETVBUF_REVERSED.
8429 * tests/semantics.at (AC_FUNC_SETVBUF_REVERSED): New test.
8431 2006-12-01 Eric Blake <ebb9@byu.net>
8433 * lib/autoconf/c.m4 (AC_LANG_INT_SAVE): Avoid newline, to aid in
8434 cross-compiling from cygwin to mingw.
8435 Reported by Bob Rossi. This resurrects the 2000-11-30 patch to
8436 aclang.m4, which was mistakenly removed in the 2001-09-17 patch
8437 to lib/autoconf/c.m4.
8439 2006-12-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8441 * lib/m4sugar/m4sh.m4 (_AS_ECHO_PREPARE): Use a longer test
8442 string for more reliable failure. Wrap the entire test that
8443 causes the broken Solaris printf to dump core, in a subshell,
8444 so the segmentation fault message is reliably suppressed.
8445 Fix shell expansion errors by using /usr/ucb/echo always;
8446 avoid an error on systems without it by another subshell.
8447 Avoid m4 expansion of `$1'. Set the zeroth argument of the
8448 subshell-$as_echo to `as_echo', for better error message.
8450 2006-11-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8452 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): If `BASH_ARGV' or
8453 `BASH_SOURCE' contain a newline, set them to empty, as they may
8456 2006-11-27 Paul Eggert <eggert@cs.ucla.edu>
8458 Turn AC_FUNC_SETVBUF_REVERSED into a noop. It's been obsolete for
8459 years and is too hard to maintain now. The last straw was
8460 reported by Jerker Baeck in
8461 <http://lists.gnu.org/archive/html/autoconf/2006-11/msg00102.html>.
8462 * NEWS: AC_FUNC_SETVBUF_REVERSED is now obsolete.
8463 * doc/autoconf.texi (Particular Functions): Move
8464 AC_FUNC_SETVBUF_REVERSED from here...
8465 (Obsolete Macros): ... to here. Say that it does nothing now.
8466 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
8467 Turn into (almost) a no-op.
8469 * lib/autoconf/c.m4 (AC_PROG_GCC_TRADITIONAL, AC_C_CONST):
8471 Do not recommend via AN_FUNCTION, AN_IDENTIFIER, or AN_HEADER.
8472 These macros are obsolescent and new applications shouldn't need them.

8483 @VAR1@VAR2 has unspecified behavior. Problem reported by
8485 * NEWS: Mention this.
8487 * Makefile.am: Put only a single '#' into the copyright notice,
8488 so that it's also present in the output file. Standardize wording
8489 in makefile copyright notices to match GNU coding standards.

8503 2006-11-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8505 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Fix error
8506 in the sed script that mangles the awk script: delete up to the
8507 first exclamation mark only.
8508 * tests/torture.at (Substitute and define special characters):
8511 2006-11-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8513 Rewrite config files generation: avoid quadratic growth in
8514 the number of substituted variables by using awk instead of sed
8515 for the bulk of the substitutions.
8516 * NEWS: Mention this.
8517 * doc/autoconf.texi (Setting Output Variables): `|#_!!_#|' is also
8518 forbidden in the output (and thus input) file.
8519 * lib/autoconf/status.m4 (_AC_AWK_LITERAL_LIMIT): New macro.
8520 (_AC_OUTPUT_FILES_PREPARE): Instead of several sed scripts,
8521 generate just one large awk script for substitutions,
8522 eliminating much of the earlier complexity, while adding some
8523 new complexity. Only expand the substitution templates at
8524 configure time, for smaller configure script size. If
8525 _AC_SUBST_FILES are used, test 'awk' for working getline support
8526 at config.status time. If absent, interpolate through the
8527 shell. The awk script was written with much help
8528 from Paolo Bonzini and Paul Eggert.
8529 (_AC_SED_CMD_NUM, _AC_SED_DELIM_NUM, _AC_SED_FRAG): Removed.
8530 (_AC_SED_FRAG_NUM): Likewise.

8533 (_AC_OUTPUT_FILE): Use _AC_SUBST_CMDS.
8534 * tests/torture.at (Substitute a 2000-byte string): Also
8535 substitute a line with 1000 words, and a variable with several
8537 (Substitute and define special characters): Test awk special
8538 characters, and put substitution input strings `@foo@' in the
8539 output, to test that no recursion happens; test several other
8540 combinations from Paolo Bonzini.
8542 2006-11-25 Paul Eggert <eggert@cs.ucla.edu>
8544 * lib/autotest/general.m4 (AT_INIT): Undo recent changes
8545 that replaced echo with AS_ECHO where this wasn't necessary.
8546 Problem reportd by Ralf Wildenhues.
8547 * lib/m4sugar/m4sh.m4 (_AS_ECHO_PREPARE): Port to Solaris 7,
8548 where "/usr/bin/printf '%s\n' S" dumps core if S is long.
8549 This is Sun bug 4206210. Problem reportd by Ralf Wildenhues.
8551 2006-11-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8553 * lib/freeze.mk (GREP): Removed, no need to initialize this.
8555 2006-11-21 Paul Eggert <eggert@cs.ucla.edu>
8557 * doc/autoconf.texi (Limitations of Usual Tools): Don't claim
8558 that traditional Awk lacks 3-arg "split". It has it.
8559 Mention that FS must be a single character, and a few other
8560 99-byte limits of traditional Awk.
8561 Mention that if (i in a) doesn't work with traditional Awk.

8567 (Newline-CODE-BS-newline in command):
8568 (Single-quote-BS-newline in command):
8569 (Single-quote-newline-BS-newline in command):
8570 Use printf '%s\n' instead of echo, for portability to hosts
8571 where echo interprets backslashes. This will break on hosts
8572 that lack printf, but for now let's assume all such hosts
8573 are dead (if not, we should get reports of test failures).
8575 2006-11-17 Paul Eggert <eggert@cs.ucla.edu>
8577 'echo' has some portability problems, when given a first argument
8578 with a leading '-', or when given any argument containing '\'.
8579 Avoid using 'echo' in these cases.
8580 * bin/Makefile.am $(bin_SCRIPTS): Rewrite to avoid 'echo' entirely.

8608 * lib/autoconf/general.m4 (AC_MSG_RESULT, AC_MSG_RESULT_UNQUOTED):
8609 Don't use ECHO_T, since ECHO_N is now reliable.
8610 * lib/autotest/general.m4 (AT_INIT): Likewise.
8611 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Use sed "$script"
8612 rather than using a here-document to put the script into a file.
8613 (_AC_DO_ECHO): Hoist the eval out of the echo, so that we can
8615 * lib/m4sugar/m4sh.m4 (AS_VAR_GET): Likewise.
8616 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Use
8617 AS_ECHO_N rather than ECHO_N and ECHO_C. This doesn't fix any
8618 bug, but we might as well stop using ECHO_N and ECHO_C internally.

8621 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):

8623 operand, as AS_ECHO requires. Avoid double file name expansion.
8624 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Invoke _AS_ECHO_PREPARE.
8625 Don't set as_nl, since _AS_ECHO_PREPARE does that now.
8626 (_AS_PREPARE): Comment that _AS_ECHO_N_PREPARE is just for user code.
8627 (AS_ECHO, AS_ECHO_N, _AS_ECHO_PREPARE): New macros.
8628 * tests/c.at (AC_PROG_CPP without warnings, AC_PROG_CPP via CC):
8629 Double-quote strings that would otherwise contain M4 comments.
8630 * tests/m4sh.at (AS_ECHO and AS_ECHO_N): New test.
8632 * configure.ac (AC_INIT): Bump to 2.61a.
8635 2006-11-17 Paul Eggert <eggert@cs.ucla.edu>
8639 * configure.ac (AC_INIT): Bump to 2.61.
8642 * tests/autotest.at (Macro with backslash in a test title):
8643 Comment out for now, as this tests neither fails nor passes
8644 reliably. Problem reported by Ralf Wildenhues.
8646 2006-11-16 Paul Eggert <eggert@cs.ucla.edu>
8648 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE): Fix some typos
8649 in previous change, which caused test failures.

8722 * tests/mktests.sh (ac_exclude_list): Exclude AC_PROG_CXX_C_O, for
8723 benefit of platforms like Solaris+GCC where it is common to have a
8724 non-working g++ installation.

8738 Imported from a similar patch to gnulib by Bruno Haible.
8740 2006-11-08 Paul Eggert <eggert@cs.ucla.edu>

8759 and Stepan Kasal <kasal@ucw.cz>
8761 Handle special characters in test case titles correctly.
8762 * lib/autotest/general.m4 (AT_INIT): M4-quote and AS_ESCAPE AT_help_all
8764 (AT_SETUP): M4-quote and AS_ESCAPE the title properly everywhere.
8765 * tests/autotest.at (AT_CHECK_AT_TITLE): Add EXPANDED-TITLE-TO-TEST
8766 argument. Extend to check titles printed by ./micro-suite and
8767 ./micro-suite -l and the title in micro-suite.log.
8768 (Backquote in a test title,
8769 Single-quote in a test title,
8770 Double-quote in a test title): Don't expect failure anymore.
8771 (Backslash in a test title): Put a non-whitespace character after the
8772 backslash so that Bourne shells might actually see it as an escape
8774 (Brackets in a test title,
8775 Pound in a test title,
8776 Comma in a test title,

8792 2006-10-26 Paul Eggert <eggert@cs.ucla.edu>
8794 * tests/base.at (AC_COMPUTE_INT): Test **0** rather than 1 / 0,
8795 since powerpc-apple-darwin8-gcc-4.0.1 (Apple Computer, Inc. build
8796 5363) simply issues a warning when dividing by zero at compile
8797 time. Problem reported by Elias Pipping.
8799 2006-10-26 Eric Blake <ebb9@byu.net>
8802 * doc/autoconf.texi (Evaluation Macros): Improve the example to
8803 show effect on macros that expand with commas.

8830 * lib/autoconf/specific.m4 (_AC_SYS_LARGEFILE_MACRO_VALUE):
8831 If FUNCTION-BODY is nonempty, use AC_LINK_IFELSE rather than
8832 AC_COMPILE_IFELSE, to work around problem with OSF/1 4.0F fseeko
8833 reported by Nelson H. F. Beebe for Coreutils 6.4.
8835 * tests/tools.at (autoconf --trace: user macros): Remove test
8836 for tracing multiline macros, since m4 1.4.7a uses a different
8837 way to number lines. Problem reported by Ralf Wildenhues.
8839 2006-10-24 Stepan Kasal <kasal@ucw.cz>

8915 (Imported from Automake.)
8916 * build-aux/install-sh (posix_mkdir): Reject FreeBSD 6.1 mkdir -p -m,
8917 which incorrectly sets the mode of an existing destination
8918 directory. In some cases the unpatched install-sh could do the
8919 equivalent of "chmod 777 /" or "chmod 0 /" on a buggy FreeBSD
8920 system. We hope this is rare in practice, but it's clearly worth
8921 fixing. Problem reported by Alex Unleashed in
8922 <http://lists.gnu.org/archive/html/bug-autoconf/2006-10/msg00012.html>.
8923 Also, don't bother to check for -m bugs unless we're using -m;
8924 suggested by Stepan Kasal.

8933 Report from Bruno Haible.
8935 2006-03-10 Alexandre Duret-Lutz <adl@gnu.org>

8975 2006-10-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8977 * lib/autoconf/functions.m4 (AC_FUNC_OBSTACK): In the test,
8978 include the default headers, and redefine obstack_chunk_alloc
8979 and obstack_chunk_free. Fixes false failure with glibc.

9000 * lib/m4sugar/m4sh.m4 (AS_TEST_X): New macro.
9001 (AS_EXECUTABLE_P): Use as_test_x rather than as_executable_p.
9002 (_AS_TEST_PREPARE): Set as_test_x rather than as_executable_p.
9003 Use a better substitute, by inspecting the output of "ls"
9004 rather than just using ":".
9005 * lib/autoconf/general.m4 (_AC_LINK_IFELSE): Use AS_TEST_X
9006 rather than AS_EXECUTABLE_P, since we needn't worry about
9007 non-regular files here.
9009 * NEWS: Autoconf-generated shell scripts no longer export BIN_SH,
9010 due to configuration hassles with this. See Tonya Underwood's report

9022 * lib/m4sugar/m4sh.m4 (AS_BOURNE_COMPATIBLE): Move the
9023 initialization which is not inherited through the environment
9024 (_AS_BOURNE_COMPATIBLE): ... to this new macro.
9025 (_AS_RUN): Call _AS_BOURNE_COMPATIBLE, not AS_BOURNE_COMPATIBLE.

9032 2006-10-06 Paul Eggert <eggert@cs.ucla.edu>
9034 * lib/autoconf/c.m4 (_AC_PROG_PREPROC_WORKS_IFELSE): Remove
9035 comment about ac_cpp_err; it was incorrect, and anyway
9036 ac_cpp_err is being removed below.
9037 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE): Don't
9038 set ac_cpp_err to 'yesyes' if preproc_warn_flag and werror_flag
9039 are both 'yes'. In fact, don't bother setting ac_cpp_err at all;
9041 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't log our funky tests
9042 with werror_flag and conftest.err and so forth. This is more
9043 compatible with how _AC_PROG_PREPROC_WORKS_IFELSE behaves,
9044 and anyway the user shouldn't normally want to see this gorp logged.
9045 Problem reported by Ralf Wildenhues.
9046 * lib/autoconf/lang.m4 (AC_LANG_WERROR): werror_flag's default is
9047 empty, not 'no', since the rest of the code uses 'test -z'.
9049 2006-10-04 Paul Eggert <eggert@cs.ucla.edu>
9051 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE):
9052 Use a single call to AC_DO_TOKENS rather than multiple, for
9054 (_AC_LINK_IFELSE): Test that resulting file is executable.
9055 Problem reported by mwoehlke in
9056 <http://lists.gnu.org/archive/html/bug-coreutils/2006-10/msg00048.html>.
9058 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Use "test -x /" rather
9059 than creating a file to use with test -x; this is much faster.
9061 2006-10-02 Bruno Haible <bruno@clisp.org>
9063 * lib/autom4te.in (Automake-preselections): Add
9064 AM_GNU_GETTEXT_INTL_SUBDIR, for automake 1.10.
9066 2006-09-27 Stepan Kasal <kasal@ucw.cz>
9068 * doc/autoconf.texi (Writing testsuite.at): Fix a typo: for
9069 standard error, `experr' should be used, not `expout'.

9073 * lib/autoconf/functions.m4 (AC_FUNC_FSEEKO): Don't compile the
9074 fseeko testing program twice; just use the earlier result.
9075 * lib/autoconf/specific.m4 (_AC_SYS_LARGEFILE_MACRO_VALUE):
9076 Set cache var to 'unknown' (not 'no') if leaving the macro unset
9077 still doesn't let the program compile.
9078 (AC_SYS_LARGEFILE): Test for _LARGE_FILES only if earlier tests
9081 * lib/autoconf/functions.m4: Fix problems reported by Ralf Wildenhues.
9082 (AC_FUNC_ERROR_AT_LINE): Don't bother to check for error.h. Just
9083 include it, without including anything else.
9084 (AC_FUNC_FSEEKO): Avoid gcc -Wall warnings about constant
9086 (AC_FUNC_STRNLEN): Require AC_USE_SYSTEM_EXTENSIONS.

9090 * lib/autoconf/functions.m4 (AC_FUNC_ERROR_AT_LINE): Check for
9091 `error.h', and include it, for a `error_at_line' prototype.
9092 Use a nonempty format string in the link test.
9093 * lib/autoconf/functions.m4 (AC_FUNC_WAIT3): Include <sys/wait.h>,
9094 for a declaration of wait3.

9099 * doc/autoconf.texi (Generic Declarations): Clarify that AC_CHECK_DECL
9100 can apply to constants too, and that it checks for macro defns.
9101 * lib/autoconf/general.m4 (AC_CHECK_DECL): Assume C89 or better,

9103 values. Problem reported by Ralf Wildenhues.

9318 broken lex libraries like native ia64-hp-hpux11.22; see
9319 <http://sources.redhat.com/ml/binutils/2003-12/msg00337.html>, and

9448 rather than "#if HAVE_STDLIB_H", so that it now works with "gcc
9449 -Wundef -Werror". Problem reported by David Fang in
9450 <http://lists.gnu.org/archive/html/autoconf/2006-08/msg00045.html>.

9473 problems with arg script text that doesn't end in newline, and

9476 2006-08-12 Alexandre Julliard <julliard@winehq.org> (tiny change)
9478 * lib/autoconf/libs.m4 (AC_PATH_X_DIRECT): Replace another

9510 less skeptical about "volatile", after discussion with
9511 Bruno Haible on bug-gnulib.

9517 * lib/autoconf/libs.m4 (AC_PATH_XTRA): Don't use -R if the
9518 compiler complains about it, even if things works after the
9519 complaint. Problem reported by Peter O'Gorman.

9522 CPPFLAGS, and LDFLAGS better. Problem reported by Bruno Haible.

9525 2006-07-17 Paul Eggert <eggert@cs.ucla.edu>
9527 * lib/autoconf/libs.m4 (AC_PATH_XTRA): Do the check for space
9528 after -R regardless of host. Patrick Welche reports that this

9540 under AC_C_VOLATILE.
9541 (Volatile Objects): Be a little less skeptical about what
9542 "volatile" means. Derived from thoughts by Ben Pfaff in
9543 <http://lists.gnu.org/archive/html/bug-gnulib/2006-07/msg00092.html>.
9545 2006-07-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

9549 2006-07-07 Paul Eggert <eggert@cs.ucla.edu>
9551 * tests/torture.at (Configuring subdirectories): Set CONFIG_SITE
9552 more globally, since the 2006-06-30 patch didn't suffice. Problem
9553 reported by Keith Marshall. Also, don't bother with builddir2,
9554 since it shouldn't be needed any more.
9556 2006-07-07 Paolo Bonzini <bonzini@gnu.org>

9575 2006-07-02 Paul Eggert <eggert@cs.ucla.edu>
9577 * lib/autoconf/types.m4 (AC_TYPE_LONG_LONG_INT):
9578 Require that long long int be at least 64 bits wide. C99 requires
9579 this and enough programs depend on it so we should check for it.
9580 Bruno Haible reports in
9581 <http://lists.gnu.org/archive/html/bug-gnulib/2006-06/msg00286.html>
9582 that long long int is 32 bits wide with some nonstandard compilers.

9585 2006-06-30 Paul Eggert <eggert@cs.ucla.edu>
9587 * tests/torture.at (Configuring subdirectories): Set CONFIG_SITE
9588 to a nonexistent file, so that we don't have to worry about
9589 a local site configuration that doesn't use /usr/local.
9590 Problem reported by Keith Marshall in
9591 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00133.html>.
9593 2006-06-28 Paul Eggert <eggert@cs.ucla.edu>
9595 * doc/autoconf.texi: Be more consistent about using @acronym with
9596 "HP" and "HP-UX". Remove mention of OSF; the old version wasn't
9597 quite right (it talked about "OSF/Tru64", even though the
9598 operating systems were called OSF/1, Digital UNIX, and Tru64 UNIX,
9599 and it even mentioned "OSF 4"!) and at this point there's little
9600 reason to talk about OSF any more, since it died in 1994.
9601 (Specific Compiler Characteristics): Simplify example of
9602 negative-size array.
9603 (File Descriptors): Reorder to make the text flow better.
9604 Remove joke about "appreciate the various levels"; I didn't get it.
9605 Add remark about HP-UX sh -x bug with stderr noted by Bob Proulx in
9606 <http://lists.gnu.org/archive/html/bug-coreutils/2006-06/msg00225.html>.
9607 (File Descriptors, Limitations of Usual Tools):
9608 Tone down the advice against renaming or removing open files.
9609 (Limitations of Usual Tools): Add a new section, on 'rm'.
9611 2006-06-26 Stepan Kasal <kasal@ucw.cz>
9613 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Use -lX11, not
9614 -lXt in LIBS, idea from Karsten Hopp; this was due since
9617 2005-09-18 Paul Eggert <eggert@cs.ucla.edu>
9618 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Look for X11/Xlib.h
9619 and XrmInitialize rather than X11/Intrinsic.h and XtMalloc
9620 (which belong to Xt, not X itself). See Debian bug 327655.
9622 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9624 * configure.ac (AC_INIT): Bump to 2.60a.

9644 datarootdir-related errors only if AC_DATAROOTDIR_CHECKED is
9646 * doc/autoconf.texi (Changed Directory Variables): New node,
9647 to document the whole `datarootdir' business a bit better.
9649 * tests/torture.at (datarootdir workaround): Extend test.
9650 Prompted by report by Alexandre Julliard.
9652 2006-06-22 Paul Eggert <eggert@cs.ucla.edu>
9654 * lib/autoconf/c.m4 (_AC_PROG_CC_C89): Check for C89 incompatibility
9655 when using default mode of IBM C 6 for AIX. Problem and two-line
9656 fix reported by Larry Jones.
9658 2006-06-22 Alexandre Julliard <julliard@winehq.org>
9660 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Avoid warning
9661 about literal '${datarootdir}' if a definition is found in the
9664 2006-06-20 Paul Eggert <eggert@cs.ucla.edu>
9666 * NEWS: Use "M4" rather than "m4" when appropriate.
9667 Problem reported by Eric Blake.
9668 * doc/autoconf.texi: Likewise.
9669 Use @acronym around BSD, GCC, and GNU when appropriate.
9670 (Why GNU M4): Renamed from "Why GNU m4".
9671 (Redefined M4 Macros): Mention that Posix
9672 m4wrap takes only 1 argument, but GNU M4 1.4.x takes more.
9673 (Buffer Overruns): Mention size_t and ptrdiff_t as alternatives
9676 2006-06-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9678 * bin/autom4te.in (handle_output): Do not forbid the empty
9680 * tests/tools.at (autoconf: the empty token): New test.
9682 2006-06-20 Stepan Kasal <kasal@ucw.cz>
9684 * lib/m4sugar/m4sugar.m4 (m4_init): Merge the two m4_wrap
9685 calls, so that we do not care whether they are LIFO or FIFO;
9686 in the m4_wrap, do not check which diversion is the topmost
9687 one, just check that the stack is balanced at the end.
9688 * lib/m4sugar/m4sh.m4 (AS_INIT): We are going to change the
9689 base diversion forever--pop the previous diversion before
9690 opening the new one; consequently, remove the m4_wrap call.
9691 * lib/autotest/general.m4 (AT_INIT): Likewise.
9692 * tests/m4sugar.at: Do not use
9693 m4_wrap([m4_diversion_pop([..])]), for educational purposes.

9696 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9698 * NEWS: Document that m4wrap/m4_wrap might not be LIFO.
9699 * doc/autoconf.texi (Redefined M4 Macros): Likewise.
9700 Rework example of m4wrap token-pasting trouble so that it doesn't
9701 care whether it's LIFO or FIFO.
9702 Fix some "contrary to"s that are awkward in English.
9704 2006-06-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9706 * lib/autoconf/types.m4 (_AC_TYPE_INT): Set `$ac_cv_c_int$1_t'
9707 to `yes' instead of `int$1_t' if the type is found, for more
9708 consistent configure output (where $1 is the number of bits).
9709 (_AC_TYPE_UINT): Likewise for `uint$1_t'.
9710 Suggested by Bruno Haible.
9712 * lib/autoconf/types.m4 (_AC_TYPE_UNSIGNED_INT): Solaris 2.5.1
9713 needs _UINT8_T and _UINT64_T defines as well, to avoid clashes
9714 with system headers. Report by Bruno Haible.
9716 2006-06-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9718 * config/config.guess, config/config.sub: Sync from upstream.
9720 * bin/Makefile.am (autoconf.in): Use `--melt' for autom4te,
9721 in order to avoid picking up an older installed frozen m4sh.m4f.
9722 Besides an outdated shell startup, this could have been created
9723 by an earlier M4 version with incompatible frozen file format.
9725 2006-06-16 Paul Eggert <eggert@cs.ucla.edu>
9727 * README: Recommend m4 1.4.4 instead of 1.4.3..
9728 * doc/autoconf.texi: Likewise.
9729 (Special Chars in Names): Say that $(.FOO) is portable, as
9730 suggested by Stepan Kasal.
9731 (Installation Directory Variables, Build Directories):
9732 (Automatic Remaking, Subdirectories, Fortran Compiler):
9733 (Making testsuite Scripts, Defining Directories):
9734 Quote variable usages better.
9735 (Making testsuite Scripts): Add clean-local rule to makefile
9736 snippet, by Eric Blake.
9737 (Installation Directory Variables): Fix table item font.
9738 Reword slightly to clarify. Generalize advice about
9739 not using special characters to include all file-related
9740 vars, not just VPATH.
9741 (Special Chars in Variables): Warn about special characters in
9743 (Assignments): Clarify default-value example as suggested by
9745 <http://lists.gnu.org/archive/html/autoconf-patches/2006-06/msg00072.html>.
9746 (Special Shell Variables): Note leading ./ or ../, as suggested
9748 (Limitations of Builtins): Under cd, warn about CDPATH.
9749 (The Make Macro MAKEFLAGS): Untabify. Problem reported by
9752 2006-06-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9754 * doc/autoconf.texi (Configuration Actions): Remove duplicate
9755 `@var', for texi2html.
9756 (Systemology): Some more word wrapping, for DVI output.
9757 (autom4te Invocation): The short option for `--melt' is `-M',
9760 2006-06-15 Paul Eggert <eggert@cs.ucla.edu>
9762 * doc/autoconf.texi: More formatting and English tweaks,
9763 many suggested by Ralf Wildenhues.
9764 Reword to avoid "@code{...}'s" and the like, since it's ugly
9765 with Emacs info mode. discontents -> woes.
9766 Put a few "will"s back. time stamp -> timestamp.
9767 side-effect -> side effect.
9769 2006-06-14 Paul Eggert <eggert@cs.ucla.edu>
9771 * doc/autoconf.texi (Initializing configure, Shell Substitutions):
9772 Warn about $@ not persisting. Problem reported by Julien Danjou in
9773 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=372179>.
9774 (Special Chars in Names): Renamed from Leading _ in Macro Names.
9775 Mention other special chars, too.
9777 2006-06-14 Eric Blake <ebb9@byu.net>
9779 * doc/autoconf.texi (The Make Macro MAKEFLAGS): New node.
9781 2006-06-13 Paul Eggert <eggert@cs.ucla.edu>
9783 * doc/autoconf.texi: Some systematic minor improvements, as
9784 follows. Use "makefile" when talking about makefiles
9785 generally (which might be named "makefile" or "Makefile" or even
9786 "foo.mk"), "Makefile" when talking about a specific makefile
9787 called "Makefile". This unclutters the text from weird quotes
9788 (e.g., "`Makefile's" in info mode). Similarly, use "@var{foo}
9789 values" rather than "@var{foo}s" and similar constructs containing
9790 "}s". Use "Make rules" rather than "Makefile rules". Minor
9791 English-language improvements. Change the prefix "sub-" to "sub"
9793 Put blank lines around examples more consistently.
9794 Avoid "rather" and "very" as intensifiers.
9795 Avoid "will" as an auxiliary.
9796 (Limitations of Make): Split this node into....
9797 (Portable Make, $< in Ordinary Make Rules, Failure in Make Rules):
9798 (Leading _ in Macro Names, Backslash-Newline-Newline):
9799 (Backslash-Newline Comments, Long Lines in Makefiles):
9800 (Macros and Submakes, The Make Macro SHELL, Comments in Make Rules):
9801 (obj/ and Make, make -k Status, VPATH and Make):
9802 (VPATH and Double-colon, $< in Explicit Rules):
9803 (Automatic Rule Rewriting, OSF/Tru64 Directory Magic):
9804 (Make Target Lookup, Single Suffix Rules, Timestamps and Make):
9805 New nodes, resulting from splitup of Limitations of Make.
9806 All cross-references changed. Raise the top node from
9807 a section to a chapter, and all subnodes accordingly.
9808 Redo the introductory wording to match the new organization.
9809 (Installation Directory Variables): Use an example that is
9810 closer to what Autoconf actually does. Mention that VPATH's
9811 value should not contain metacharacters or white space.
9812 (Fortran Compiler): Fix a VPATH bug in an example.
9813 (Leading _ in Macro Names): Mention that this problem is no longer
9814 of practical concern.
9815 (VPATH and Make): Reword the advice to make it clearer
9816 that Autoconf and Automake support VPATH in non-GNU make, but
9817 many packages have bugs in this area.
9818 ($< in Explicit Rules): Refer to Build Directories rather
9819 than using a (non-VPATH-safe) example.
9820 (Automatic Rule Rewriting): Mention the sort of disaster that
9821 can ensue with Solaris-style rule rewriting with VPATH.
9823 2006-06-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9825 * doc/install.texi (Compilers and Options): Weaken the
9826 suggestion to use GNU make for VPATH builds.
9828 * lib/autom4te.in (Automake-preselections): Add AM_PROG_CXX_C_O,
9829 AM_PROG_F77_C_O, AM_PROG_FC_C_O, AC_FC_SRCEXT, AC_FC_FREEFORM.

9836 * doc/autoconf.texi (Installation Directory Variables):
9837 Drop extra @samp from `@table @samp' item.
9838 (Limitations of Usual Tools): Comment fix.
9839 Do not nest @samp just to point to other table items.
9840 (Writing testsuite.at) <AT_CHECK>: The second argument to
9841 `@dvar' is already @samp'ed.
9842 (Making testsuite Scripts) <AC_CONFIG_TESTDIR>: Likewise,
9843 do not use @var in the second argument.
9845 2006-06-07 Paul Eggert <eggert@cs.ucla.edu>
9847 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Look for
9848 $as_shell.exe too. Problem reported by Andreas Buening in
9849 <http://lists.gnu.org/archive/html/autoconf/2006-06/msg00038.html>.
9851 2006-06-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9853 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA): Work around
9854 `unused variable' compiler warning, for `-Wall -Werror'.
9855 Reported by Jaap Haitsma in
9856 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00012.html>.
9858 2006-06-06 Paul Eggert <eggert@cs.ucla.edu>
9860 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Remove core file, in
9861 case the compiler dumps core. Problem reported for
9862 OpenServer 5.0.7 by Tim Rice in
9863 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00019.html>.

9867 2006-06-06 Tim Rice <tim@multitalents.net>.
9869 * lib/freeze.mk: Quiet check-forbidden-patterns so the string
9870 "ERROR" only shows up in "make check" output if there is an

9894 * config/texinfo.tex: Sync from upstream.
9896 * bin/autoreconf.in: Trace `LT_CONFIG_LTDL_DIR'; if it has been
9897 seen, invoke libtoolize with `--ltdl' argument.
9898 * lib/autom4te.in (Autoreconf-preselections): Adjust.
9900 Suggested by Eric Blake.
9902 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
9904 * NEWS: Whoops! AC_FUNC_STRNLEN isn't obsolescent. Problem

9914 * doc/autoconf.texi: Modernize some of the references to Solaris.
9916 2006-06-05 Stepan Kasal <kasal@ucw.cz>
9918 * lib/m4sugar/m4sugar.m4 (m4_require): Modify the error
9919 message issued by AC_REQUIRE.
9920 * tests/m4sugar.at: Check m4_require's error message.
9921 * tests/base.at: Check AC_REQUIRE's error message.
9922 * tests/local.at (AT_CHECK_M4): New macro, almost identical
9924 (AT_CHECK_AUTOM4TE): ... which is now a thin wrapper around
9926 (AT_CHECK_AUTOCONF): Use AT_CHECK_M4; no longer support
9927 `expout' as the last parameter.
9928 * tests/tools.at: Adapt to the above change.
9930 2006-06-04 Stepan Kasal <kasal@ucw.cz>
9932 * doc/autoconf.texi (Limitations of Usual Tools): Correct
9933 information about race-free implementations of mkdir.
9935 2006-06-04 Eric Blake <ebb9@byu.net>

9942 2006-06-04 Paul Eggert <eggert@cs.ucla.edu>
9944 * NEWS: GNU make now recommended for VPATH builds.
9945 Mention that some macros are now documented to be obsolescent.
9946 * doc/autoconf.texi:
9947 Prefer "current" to "modern" to describe
9948 currently-used (albeit perhaps old-fashioned) hosts.
9949 Mention which ancient features no longer need to be worried about.
9950 setgid -> set-group-ID
9951 setuid -> set-user-ID (these are the Posix terms)
9952 Fix some misuses of "only".
9953 (AC_C_BACKSLASH_A, AC_C_CONST, AC_C_PROTOTYPES):
9954 (AC_C_STRINGIZE, AC_C_VOLATILE, AC_FUNC_CLOSEDIR_VOID):
9955 (AC_FUNC_GETPGRP, AC_FUNC_LSTAT, AC_FUNC_MEMCMP):

9962 Mention that these macros are obsolescent.
9963 (Installation Directory Variables): shall -> should
9964 (File Descriptors): Mention that 0, 1, 2 might get reopened.
9965 Mention that it's now safe to use 3 and 4.
9966 (Limitations of Usual Tools): cp -r is now specified by Posix.
9967 Omit longwinded and obsolescent discussion of cp -f.
9968 Modernize discussion of expr, ls.
9969 (Limitations of Make): Modernize discussion of VPATH builds.
9970 Mention $? as a workaround in some cases.
9971 * doc/install.texi (Basic Installation):
9972 Mention "./configure; make; make install" first. Be more
9973 specific about why this file is generic. Remove unnecessary
9974 parens. Remove misleading "only". Remove obsolete advice
9975 about csh. Don't say "configure" takes awhile; say it
9976 might take a while. Suggest CFLAGS=-g rather than CFLAGS=-O2,
9977 and CC=c99 rather than CC=c89, as these are blessed by current
9978 Posix. Recommend GNU make if doing a VPATH build.
9980 2006-06-03 Paul Eggert <eggert@cs.ucla.edu>
9982 * doc/autoconf.texi: Use a consistent style "$ @kbd{...}" for
9983 examples involving shell prompts.
9985 2006-06-02 Stepan Kasal <kasal@ucw.cz>
9986 and Paul Eggert <eggert@cs.ucla.edu>
9988 * doc/autoconf.texi (Here-Documents): Add details about the
9989 pre-ksh93g bug. Reword slightly to make it clearer. Consistently
9990 use "here-documents" instead of "here documents".
9992 2006-06-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9994 * config/texinfo.tex, doc/standards.texi: Sync from upstream.

10001 2006-05-31 Paul Eggert <eggert@cs.ucla.edu>
10003 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be even more conservative
10004 about quoting the case statement, just in case.
10005 * doc/autoconf.texi (Here-Documents): Mention that the ksh bug
10006 was fixed in ksh93g; reported by Ralf Wildenhues.
10008 2006-05-31 Stepan Kasal <kasal@ucw.cz>
10010 * doc/autoconf.texi (System Services): Do not document

10017 2006-05-31 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10019 * lib/m4sugar/m4sh.m4 (_AS_DIRNAME_PREPARE): Guard against test
10020 argument with leading hyphen. Problem reported by Paul Eggert.
10022 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
10024 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be more conservative
10025 about quoting ac_try: quote all of it, if any of it seems suspicious.
10026 This means we don't have to worry about ${ or sed any more.
10027 Also, double-quote the case statement, to work around misuses via
10028 underquoting as reported by Ralf Wildenhues in
10029 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00169.html>.
10030 (_AC_EVAL_STDERR): Revert, since evidently some packages rely on this
10031 undocumented and dangerous macro.

10043 * lib/autoconf/general.m4: Revert AC_TRY_EVAL and AC_TRY_COMMAND,
10044 since evidently some packages rely on the old, broken behavior.
10045 Problem reported by Ralf Wildenhues in
10046 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00160.html>.
10047 (AC_TRY_EVAL, AC_TRY_COMMAND, _AC_EVAL): Go back to the
10048 pre-2006-05-26 definitions, but leave in the comments that
10049 these macros are dangerous and should not be used.
10050 (_AC_DO_ECHO): Renamed from _AC_EVAL_ECHO. All callers changed.
10051 (_AC_DO): Renamed from _AC_EVAL. All callers changed.
10052 (_AC_DO_STDERR): Renamed from _AC_EVAL_STDERR. All callers changed.
10053 (_AC_DO_VAR): Renamed from AC_TRY_EVAL.

10056 2006-05-29 Paul Eggert <eggert@cs.ucla.edu>
10058 * lib/autoconf/status.m4 (AC_OUTPUT_MAKE_DEFS): Rewrite to avoid
10059 the use of 'tr', since this is our only use of 'tr'.

10062 and Paul Eggert <eggert@cs.ucla.edu>
10064 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE):
10065 Don't assume 'grep' works on long lines, since AIX grep doesn't.
10067 2005-05-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10069 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Do not use `grep' on
10070 the output file in the `${datarootdir}' test.
10072 2005-05-28 Stepan Kasal <kasal@ucw.cz>
10073 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10075 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If we have not seen
10076 mention of `datarootdir' in the input file(s), but literal
10077 `${datarootdir}' in the output file, and we haven't warned yet,
10078 then warn as well: the user may have (erroneously) used
10079 `AC_SUBST([mydatadir], [$datadir/my])' instead of the correct
10080 `AC_SUBST([mydatadir], ['${datadir}/my'])'.
10081 * tests/torture.at (datarootdir workaround): Extend this test.

10085 and Paul Eggert <eggert@cs.ucla.edu>
10087 * doc/autoconf.texi (autoheader Invocation): The first argument to
10088 `AC_DEFINE_UNQUOTED' need not be a literal. Mention the
10089 alternatives and clear up the language a bit.
10091 2006-05-27 Paul Eggert <eggert@cs.ucla.edu>
10093 * NEWS: Reword notice for AC_TRY_COMMAND, AC_TRY_EVAL,
10094 ac_config_guess, ac_config_sub, ac_configure.
10095 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
10096 Fix typo that prevented an unnecessary space from being removed.
10097 Problems reported by Ralf Wildenhues in:
10098 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00143.html
10100 2006-05-26 Paul Eggert <eggert@cs.ucla.edu>
10102 * doc/autoconf.texi (Particular Programs, Limitations of Usual Tools):
10103 Use better wording to talk about AC_PROG_MKDIR_P's thread-safety.
10104 Don't use the term "thread-safe" to talk about mkdir race
10105 conditions, since the problem is more a process than a thread
10106 issue. Problem reported by Stepan Kasal in:
10107 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00088.html
10108 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Use code that mimics
10109 the test for 'install' more closely. Look at MKDIR_P first.
10110 Look in the PATH, and at /opt/sfw/bin.
10111 Look for a 'gmkdir' program as well (Solaris 10 /opt/sfw/bin/gmkdir).
10112 Don't bother to try mkdir -p, since we already check mkdir --version;
10113 just look at the version number. (There's no easy way to check
10114 for race-free implementations.)
10115 * tests/tools.at (autoconf: subdirectories): Adjust to above
10116 changes, since MKDIR_P now might end in "/mkdir -p".
10118 * doc/autoconf.texi (autoheader Invocation): Mention that the
10119 first arg of AC_DEFINE_UNQUOTED must be a literal.
10120 Problem reported by Ben Pfaff in
10121 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00090.html>.
10123 * NEWS: Mention that AC_TRY_COMMAND and AC_TRY_EVAL may be removed.
10124 * doc/autoconf.texi (Special Chars in Variables): New section.
10125 (Preset Output Variables): Warn about special chars in CPPFLAGS.
10126 (Installation Directory Variables): Quote $(datadir) better.
10127 (Limitations of Builtins): Describe some of eval's trickiness.
10129 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Simplify quoting.
10130 * lib/autoconf/fortram.m4 (_AC_PROG_FC_V_OUTPUT): Likewise.
10131 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Put leading space
10132 in front of every arg, not just trailing args. Quote apostrophes.
10133 (_AC_EVAL_ECHO): New macro.
10134 (_AC_EVAL, AC_EVAL_STDERR): Use it. Quote arg of eval.
10135 (AC_TRY_EVAL, AC_TRY_COMMAND): Mention that these macros might get
10137 (_AC_LINK_IFELSE): Use proper rule for shell continuation lines,
10138 exposed by quoting of eval argument. Put the command on line line
10140 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): Use eval more safely.
10141 (_AC_PATH_X, AC_PATH_X): Quote more safely.
10142 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Use eval more safely.
10143 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Don't use eval.
10144 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Minor style change.
10145 Handle special chars in prefix, ac_srcdir, ac_aux_dir.
10146 Use eval more safely.
10147 (_AC_OUTPUT_CONFIG_STATUS): Adjust to above changes.
10148 * lib/m4sugar/m4sh.m4 (AS_VAR_GET): Note that this API needs
10150 * tests/base.at (AC_TRY_COMMAND): Use proper rule for shell continuation
10151 lines, exposed by quoting of eval argument.

10154 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10156 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Drop the
10157 initialization of `ac_cv_exeext', do not override it if it was
10158 already set, unless it was set to `no', for compatibility with
10159 Autoconf-2.13, and comment this.
10160 Do not export `ac_cv_exeext', Libtool hasn't needed this for years.
10161 (_AC_COMPILER_EXEEXT_DEFAULT): Likewise, do not export it.
10162 (_AC_COMPILER_EXEEXT_WORKS, _AC_COMPILER_EXEEXT_CROSS): Typos.
10163 * doc/autoconf.texi (Compilers and Preprocessors) <EXEEXT>:
10164 Document that this test may be overridden by setting
10167 2006-05-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10169 Revert these two patches:
10171 2006-04-06 Eric Blake <ebb9@byu.net>
10172 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_O): Inside cache
10173 check, s/ac_exeext/ac_cv_exeext/. Fixes regression introduced
10176 2006-04-01 Stepan Kasal <kasal@ucw.cz>
10177 Clean up _AC_COMPILER_EXEEXT* macros.
10178 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't try to
10179 detect exeext, it will be done by _AC_COMPILER_EXEEXT_O; just set
10180 ac_file to the name of the default output file and call
10181 _AC_COMPILER_EXEEXT_WORKS. Move the definition of ac_files and the
10182 initial `rm' of the candidate files...
10183 (_AC_COMPILER_EXEEXT): ... here and simplify them. Moreover, use
10184 the same list in subsequent `rm' calls, and for the temporary
10185 redefinition of ac_clean_files; call _AC_COMPILER_OBJEXT at the end,
10186 and don't call the other _AC_COMPILER_EXEEXT_* macros directly, use...
10187 (_AC_COMPILER_EXEEXT_TESTS): ... this new macro.
10188 (_AC_COMPILER_EXEEXT_O): Don't export ac_cv_exeext, it's not needed (or
10189 no longer needed) by libtool. Make it a cache check.
10190 (_AC_COMPILER_EXEEXT_CROSS): Remove the comment, it was obviously
10191 copied here by mistake.
10192 (AC_NO_EXECUTABLES): Redefine _AC_COMPILER_EXEEXT_TESTS, not
10193 _AC_COMPILER_EXEEXT.
10194 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX, AC_PROG_OBJC): Do not call
10195 _AC_COMPILER_OBJEXT directly.
10196 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
10198 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10200 * doc/autoconf.texi (Limitations of Usual Tools) < sed (`t')>:
10201 Fix description of how the buggy `sed' works.
10203 2006-05-25 Noah Misch <noah@cs.caltech.edu>
10205 Sync from Automake:
10207 * lib/Autom4te/XFile.pm (lock): Allow EOPNOTSUPP, besides
10208 ENOLCK. Only mention `make -j' when applicable. Only raise
10209 fatal errors when `make -j' is involved. Improve error message.
10211 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10213 * doc/autoconf.texi (Here-Documents): We now know more about
10214 the variable expansion in here documents bug.
10215 Thanks to Tim Rice and Stepan Kasal.
10217 * doc/autoconf.texi (Making testsuite Scripts): Add an example
10218 how to use TESTSUITEFLAGS. Suggested by Eric Blake.
10220 2006-05-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10222 * tests/autotest.at (Multiline command from M4 expansion):
10223 No failure to be expected if the shell quotes newlines in
10224 commands in the `set -x' output. Report by Tim Rice.
10227 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
10229 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Don't use shell
10230 expansion in the here-documents used by config.status, as that
10231 runs afoul of the Korn shell version M-12/28/93d bug described in
10232 the Autoconf manual, and this in turn causes a Coreutils 5.95 build to
10233 fail as described by Tim Rice and diagnosed by Ralf Wildenhues in
10234 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00082.html>.
10236 2006-05-23 Jim Meyering <jim@meyering.net>
10238 * lib/autoconf/functions.m4 (AC_FUNC_LSTAT_FOLLOWS_SLASHED_SYMLINK):
10239 Fix typo introduced with 2006-04-02 change. It reversed the sense
10242 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
10244 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Simplify ac_dA and
10245 ac_dB slightly, to save bytes in the script.
10246 Max out at 50 lines, rather than 96; this is more likely
10247 (though not guaranteed) to avoid obscure 'sed' failures.
10249 2006-05-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10251 * lib/autotest/general.m4 (AT_INIT): UnixWare `tr' may interpret
10252 `tr -d -' as bad option argument. Work around this by deleting
10253 an unrelated character.
10254 Report by Tim Rice <tim@multitalents.net>.
10256 2006-05-22 Paul Eggert <eggert@cs.ucla.edu>,
10257 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
10258 Stepan Kasal <kasal@ucw.cz>
10260 * doc/autoconf.texi (Particular Programs): Do not promise that
10261 we always prefer the GNU version of the program, and that we
10262 search according to PATH; both rules can have exceptions.
10263 Update description of AC_PROG_GREP, AC_PROG_EGREP, AC_PROG_FGREP,
10264 AC_PROG_SED. Move descriptions of limitations
10265 to the Limitations of Usual Tools section.
10266 (Limitations of Usual Tools) <sed>: Mention script length
10267 limitations with Solaris /usr/ucb/sed.
10268 <grep>: Fix wording for empty alternative. Mention that -c and
10269 -l should not be combined, and that -E and -F should not be
10272 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
10273 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10275 * lib/autoconf/programs.m4 (AC_PROG_SED): Catch script length
10276 limits in Solaris 8 /usr/ucb/sed by testing a long script.
10278 2006-05-22 Stepan Kasal <kasal@ucw.cz>
10280 * doc/autoconf.texi (Defining Symbols): Literal parameter of
10281 AC_DEFINE is now passed to m4_pattern_allow.
10282 * NEWS: Mention that; likewise for AC_SUBST.
10283 * lib/autoconf/general.m4 (AC_DEFINE_TRACE_LITERAL): Pass
10284 the parameter to m4_pattern_allow.
10285 * tests/tools.at: Add a check for that.
10287 2006-05-22 Stepan Kasal <kasal@ucw.cz>
10289 * lib/autoconf/status.m4: Fix typos.
10291 2006-05-21 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10293 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Remove
10294 only the files that this macro generates.
10296 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
10298 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: For
10299 the HP-UX sed limitation of 99 commands, labels do not count.
10300 * lib/autoconf/status.m4 (_AC_SED_CMD_LIMIT): Mention that
10302 (_AC_OUTPUT_HEADER): Revert the change from 2006-05-19.
10304 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
10306 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT):
10307 Import the following fix from coreutils:
10309 2006-01-13 Jim Meyering <jim@meyering.net>
10311 Invoke AC_CHECK_FUNCS(getmntent) unconditionally so that tests of
10312 $ac_cv_func_getmntent (e.g., in gl_LIST_MOUNTED_FILE_SYSTEMS) need
10313 not double-quote uses of that variable, to accommodate the rare
10314 case in which getmntent is available in none of the libraries
10315 checked. This happens at least on FreeBSD 5.0.
10317 2006-05-20 Paul Eggert <eggert@cs.ucla.edu>
10319 * lib/autoconf/general.m4 (AC_CONFIG_AUX_DIRS): Bring back
10320 ac_config_guess, ac_config_sub, and ac_configure, since evidently
10321 some other programs unwisely rely on these undocumented vars.
10322 But put in warning comments about them.
10323 Problem reported by Ralf Wildenhues in
10324 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00068.html>.
10325 * NEWS: Document that these variables are intended to go away.
10327 2006-05-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10329 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): Require AC_PROG_CXX,
10330 and set the language to C++ (analogous to the equivalent Fortran
10333 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): New macro.
10334 * doc/autoconf.texi (C++ Compiler): Document it.
10335 * lib/autoconf/fortran.m4 (_AC_PROG_FC_C_O): Adjust comment.
10338 2006-05-19 Paul Eggert <eggert@cs.ucla.edu>
10340 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Fix off-by-one bug
10341 that caused config.status to generate 100-command sed scripts; the
10342 portable limit is 99.
10344 2006-05-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10346 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Name temporary
10347 variable `ac_d' instead of `d' to avoid infringing namespace.
10348 Report by Ralf Menzel.
10350 2006-05-18 Paul Eggert <eggert@cs.ucla.edu>
10352 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Don't prepend
10353 $ac_top_build_prefix to $MKDIR_P if it's just 'mkdir -p'.
10354 * tests/tools.at (autoconf: subdirectories): New test, taken from
10355 the corresponding problem report by Ralf Wildenhues in:
10356 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00053.html
10358 * lib/autoconf/functions.m4 (AC_REPLACE_FNMATCH, AC_FUNC_FNMATCH_GNU):
10359 Quote some uses of shell variables if they might suffer unexpected
10360 globbing. This doesn't fix all instances of quoting problems that
10361 I found, just the easy ones that look safe.
10362 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR, _AC_INIT_HELP):
10363 (AC_CONFIG_AUX_DIR, AC_CONFIG_AUX_DIR_DEFAULT, AC_CONFIG_AUX_DIRS):
10364 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST, AC_CANONICAL_TARGET):
10365 (AC_CACHE_LOAD, AC_CACHE_SAVE): Likewise.
10366 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF, _AC_PATH_X_DIRECT): Likewise.
10367 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Likewise.

10373 2006-05-18 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10375 * bin/autoreconf.in ($help): Reword according to the manual.
10376 Suggested by Olly Betts.
10378 2006-05-17 Olly Betts <olly@survex.com> (tiny change)
10379 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10381 * bin/autoreconf.in: Pass the directory argument to
10382 `require_configure_ac'. Fix comment.
10383 * tests/torture.at (Configuring subdirectories): Expose this.
10384 Reported by Olly Betts.
10386 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10388 * lib/Automake/Configure_ac.pm, lib/Automake/Channels.pm,
10389 lib/Automake/FileUtils.pm, lib/Automake/Struct.pm: Sync from
10390 Automake as follows:
10392 * lib/Autom4te/Configure_ac.pm (find_configure_ac): Use
10393 `$configure_in' instead of `configure.in', to preserve
10394 directory component.
10396 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10398 * config/config.guess, config/config.sub, config/texinfo.tex,
10399 doc/make-stds.texi, doc/standards.texi: Sync from upstream.

10403 * lib/autoconf/headers.m4 (AC_HEADER_STDBOOL): Fix overly-picky
10404 test for C99 conformance; (bool) 0.5 is an integer constant
10405 expression, but (bool) -0.5 is not. Problem reported by Fedor
10406 Sergeev in <http://forum.sun.com/jive/thread.jspa?threadID=96202>.
10408 2006-05-13 Paul Eggert <eggert@cs.ucla.edu>
10410 * doc/autoconf.texi (Particular Programs): AC_PROG_MKDIR_P now
10411 sets MKDIR_P, not mkdir_p, to avoid collisions with Automake.
10412 Warn about obsolete install-sh files. Remove stray sentence
10413 fragment and fix cross reference.
10414 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Don't insist on
10415 install -d; this undoes the 2006-05-10 change.
10416 (MKDIR_P): Mark with AN_MAKEVAR.
10417 (AC_PROG_MKDIR_P): Fall back on $ac_install_sh, not $INSTALL, so
10418 that we don't require $INSTALL to be thread-safe. Move comments
10419 out of generated code. Require AC_CONFIG_AUX_DIR_DEFAULT instead
10420 of AC_PROG_INSTALL. Output a message saying that we're checking
10421 mkdir -p. Set MKDIR_P rather than mkdir_p. Do special magic for
10422 MKDIR_P instead of AC_SUBST.
10423 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE, _AC_OUTPUT_CONFIG_STATUS):
10424 Special magic for MKDIR_P, too.
10425 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Remove comment that defeated
10427 * tests/local.at (AT_CHECK_ENV): mkdir_p -> MKDIR_P.
10429 2006-05-11 Paul Eggert <eggert@cs.ucla.edu>
10431 Sync from Automake, as follows:
10433 2006-05-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10434 * config/install-sh: Initialize IFS, so field splitting isn't
10436 * config/mkinstalldirs: Likewise.
10437 * config/missing: Remove superfluous quotes. Replace all uses of
10438 `[' by `test', for consistency, and for..
10439 * config/missing (sed_minuso, sed_output): New variables.
10440 (autom4te, help2man, makeinfo): Use them. Unifies detection of
10441 `-o FILE', `--output FILE', `--output=FILE', stricter regex.
10442 Fixes `missing' to detect `--output' for help2man. Fixes
10443 PR automake/483. Report by Dennis J. Linse.
10444 (autom4te): Document in `missing --help'.
10446 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
10448 * NEWS: New macro AC_PROG_MKDIR_P. AS_MKDIR_P is now more robust.
10449 * config/install-sh: Don't use 'path' to talk about file names,
10450 as per GNU coding standards. Close a race condition reported by Ralf
10451 Wildenhues and Stepan Kasal. There is still a race condition
10452 on hosts that predate Posix 1003.1-1992, but we can't help this.
10453 Don't mishandle weird characters like space on pre-Posix hosts.
10454 Invoke mkdir at most once per dir arg on pre-Posix hosts.
10455 * doc/autoconf.texi (Programming in M4sh): Cross-reference to
10456 AC_PROG_MKDIR_P from AS_MKDIR_P.
10457 (Limitations of Usual Tools): Cross-reference to AC_PROG_MKDIR_P
10458 from mkdir. Mention that Autoconf 2.60 install-sh is safe but
10459 earlier editions are not (including Automake 1.8.3).
10460 Do not suggest mkinstalldirs for thread-safety.
10461 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Insist on an 'install'
10462 that understands -d, so that AC_PROG_MKDIR_P can fall back on $INSTALL.
10463 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Make it more robust in the
10464 presence of special characters and race conditions.
10465 * tests/local.at (AT_CHECK_ENV): Add mkdir_p to the list of variables
10466 in Autoconf's name space.
10468 2006-05-10 Bruno Haible <bruno@clisp.org>
10469 and Paul Eggert <eggert@cs.ucla.edu>

10472 from Automake with minor changes.
10473 * doc/autoconf.texi (Particular Programs): Document AC_PROG_MKDIR_P.
10475 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
10477 * config/install-sh: Update to Automake CVS version, as follows:
10478 2006-04-25 Stepan Kasal <kasal@ucw.cz>
10479 * lib/install-sh: Simplify the expr implementation of dirname.
10480 2006-04-24 Paul Eggert <eggert@cs.ucla.edu>
10481 * lib/install-sh: Handle --, and diagnose unknown options.
10483 2006-05-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10485 * tests/Makefile.am (AUTOTEST): Use `$(MY_AUTOM4TE)' instead of
10486 `./autom4te' to create `./testsuite', since the `all' target
10487 will ensure its presence, but `installcheck' should not create
10488 the uninstalled wrappers.
10490 * tests/torture.at (Unusual Automake input files): Skip if we
10491 detect automake < 1.8.
10493 2006-05-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10495 * lib/autoconf/c.m4 (AC_PROG_CC_STDC): If ac_cv_prog_cc_stdc
10496 is set to `no', then that overrides and sets ac_cv_prog_cc_c89
10497 and ac_cv_prog_cc_c99 to `no', for backward compatibility.
10500 2006-05-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10502 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Take care not to
10503 munge (multiple) white space and other oddities.
10504 * tests/torture.at (AT_CHECK_AC_ARG_VAR): Make sure to M4-escape
10505 single quotes in variable assignment.
10506 (AC_ARG_VAR, configure invocation): Adjust tests to expose this
10507 and similar failures by adding multiple spaces, tabs, and other
10508 special characters.
10509 Report and different test suggested by Francesco Romani
10510 <fromani@gmail.com> and Andrew Church <achurch@achurch.org>.
10512 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): When we escape
10513 single quotes, we only need to search for single quotes; this
10514 both simplifies the search pattern, and makes us less
10515 susceptible to `echo' variations for arguments not containing
10517 (_AC_ARG_VAR_VALIDATE): Likewise.
10519 2006-05-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10521 * doc/autoconf.texi (Special Shell Variables) <IFS>: Document
10522 `$*' and IFS concatenation issue with traditional shells and
10523 bash-2.04. Report by Seanster@Seanster.com.
10525 2006-05-03 Bruno Haible <bruno@clisp.org>
10527 * doc/autoconf.texi (Limitations of Usual Tools): Identify more
10528 precisely which Mac OS X versions have the od problem.
10530 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
10532 * doc/autoconf.texi: Use @option systematically.
10534 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
10535 and Bruno Haible <bruno@clisp.org>
10537 * doc/autoconf.texi (Limitations of Usual Tools): Add a paragraph
10539 (Integer Overflow): Mention the special case of integer division
10542 2006-05-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10544 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Cater for
10545 traditional shells like the Solaris one that do not use the
10546 first IFS character for assembling `$*'.
10547 Prompted by a related report from autoconf_bug@nro.ca.
10549 2006-05-01 Paul Eggert <eggert@cs.ucla.edu>
10550 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10552 * doc/autoconf.texi (Limitations of Builtins, Limitations of Make):
10553 Mention more problems with the -e option.
10555 2006-04-30 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10558 * doc/autoconf.texi (Systemology): Mention the Heirloom Project.
10560 * doc/autoconf.texi (Introduction, Pointers): Use `@/' liberally
10561 in URLs to improve DVI formatted output (requires texinfo 4.6).
10562 (System Services, Systemology, Shellology): Likewise.
10563 (Limitations of Usual Tools): Rewrite Mac OS X example for nicer
10566 * doc/autoconf.texi (Fortran Compiler): Do not use `@ovar' in
10568 (Runtime): Fix macro argument names to match description:
10569 `action-if-found' -> `action-if-true' and similarly.
10570 (Obsolete Macros): Likewise.
10571 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE): Likewise.
10572 (AC_COMPILE_IFELSE, AC_TRY_COMPILE, _AC_LINK_IFELSE)
10573 (AC_LINK_IFELSE, AC_TRY_LINK, AC_COMPILE_CHECK): Likewise.
10575 2006-04-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10577 * doc/autoconf.texi (Limitations of Make): Clean up markup.
10580 * doc/autoconf.texi (Portable Shell): Allow wrapped URLs, for

10593 (Integer Overflow, Null Pointers, Buffer Overruns):
10594 (Floating Point Portability, Exiting Portably): New sections.

10603 * bin/autoconf.as (me): Replace by as_me.
10605 2006-04-25 Paul Eggert <eggert@cs.ucla.edu>
10607 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Don't use AS_ERROR,
10608 since as_me isn't set yet.
10610 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
10612 Prepare for deprecation of AS_BASENAME and AS_DIRNAME, and fix
10613 a few minor bugs in this area.
10615 * doc/autoconf.texi (Programming in M4sh): Comment out the
10616 documentation of AS_BASENAME, for now.
10617 (Shell Substitutions): Do not use AS_DIRNAME in an example.

10620 * bin/autoconf.as (me): Don't use AS_BASENAME.
10621 (dir): Remove the unused variable.
10622 * lib/m4sugar/m4sh.m4 (_AS_DETECT_REQUIRED): Renamed from
10623 AS_DETECT_REQUIRED. All uses changed.
10624 (_AS_DETECT_SUGGESTED): Renamed from AS_DETECT_SUGGESTED.
10626 (_AS_DETECT_BETTER_SHELL): Put ;; at the end of a case.

10650 * doc/autoconf.texi (Introduction): The GNU Autoconf Macro
10651 Archive is not officially `GNU' any more. Update URL.
10652 (Defining Directories): Likewise
10653 * lib/autoconf/c.m4 (AC_C_RESTRICT): Update URL.
10655 2006-04-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10657 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Remove the leading
10658 newline from the `trap' code to finish `config.log'; the NetBSD
10659 /bin/sh resets the exit status after an empty command, as
10660 documented in doc/autoconf.texi.
10661 Reported by Dalibor Topic <robilad@kaffe.org>.
10663 2006-04-19 Paul Eggert <eggert@cs.ucla.edu>
10665 * doc/autoconf.texi (C Compiler): Clarify AC_C_TYPEOF.
10666 Suggested by Bruno Haible.
10668 2006-04-18 Paul Eggert <eggert@cs.ucla.edu>
10670 * configure.ac (ac_cv_sh_n_works): Don't try to test for it, since
10671 some shells (e.g., Solaris 8 /bin/sh) implement it verrrry slowly.
10672 Instead, just list the shells that we know work.
10673 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Remove 2nd arg. All uses
10674 changed. Be more cautious about the _cv_ variable.
10675 * tests/tools.at (Syntax of the shell scripts): Check the
10676 _cv_ variable once, at first, to avoid an internal autoconf error
10677 when sh -n does not work.
10679 2006-04-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10681 * lib/Autom4te/FileUtils.pm: Sync from Automake.
10683 2006-04-16 Paul Eggert <eggert@cs.ucla.edu>
10685 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Don't
10686 use ">&-" since we're only 99.999% sure that this is portable,
10687 and since the MinGW bug is fixed in a different way.
10688 * lib/autotest/general.m4 (AT_INIT): Likewise.
10690 2006-04-16 Stepan Kasal <kasal@ucw.cz>
10692 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Handle --recheck
10693 before opening config.log, to avoid hitting a bug on MinGW.
10695 2006-04-14 Paul Eggert <eggert@cs.ucla.edu>
10697 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Close
10698 AS_MESSAGE_LOG_FD before reopening it onto the log file.
10699 This works around a MinGW bug reported by Eric Paire.
10700 Make sure that all writes to the log file append to it,
10701 rather than possibly losing data.
10702 * lib/autotest/general.m4 (AT_INIT): Likewise.
10704 2006-04-14 Stepan Kasal <kasal@ucw.cz>
10706 * lib/Autom4te/FileUtils.pm (find_file): Fix a typo in the
10709 2006-04-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10713 * configure.ac (AC_INIT): Bump to 2.59d.
10715 2006-04-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10719 * Makefile.maint (news-date-check): Do not require a leading `*'
10720 before the release date in NEWS.
10722 2006-04-12 Stepan Kasal <kasal@ucw.cz>
10723 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10725 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If the templates for
10726 the instantiated file do not contain the string 'datarootdir'
10727 but contain @datadir@, @docdir@, @infodir@, @localedir@, or
10728 @mandir@, replace the reference '${datarootdir}' by the value.
10729 * tests/torture.at (datarootdir workaround): New test.
10730 * NEWS: Advertise this temporary fixup.
10731 Based on a patch by Bruno Haible, reported and analyzed by
10732 Paul Eggert and Noah Misch.
10734 2006-04-12 Eric Blake <ebb9@byu.net>
10736 * tests/autotest.at (Debugging a failed test): Fix comment.
10738 2006-04-12 Stepan Kasal <kasal@ucw.cz>
10740 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): Simplify the summary of
10741 all the changes since 2006-04-07.
10743 2006-04-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10745 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): If `ln -s file1 file2'
10746 succeeded, but `ln -s file dir' failed, take care to remove the
10747 leftover target before the next test, to prevent its spurious
10748 failure; also make sure `ln file dir' works before selecting it.
10749 Thanks to Keith Marshall for pointing this out.
10752 * lib/autotest/general.m4 (AT_INIT): Store quoted variable
10753 assignments in `at_debug_args', so that we put them correctly
10754 in the `run' script.
10755 * tests/autotest.at (Debugging a failed test): Unmark XFAIL.
10756 Reported by Eric Blake.
10758 2006-04-11 Eric Blake <ebb9@byu.net>
10760 * tests/autotest.at (AT_CHECK_AT): Add new argument, to allow
10761 top-level tests after micro-suite has been run. Used in...
10762 (Debugging a successful test, Debugging script and environment),
10763 (Debugging a failed test): ...these new tests. The first of these
10765 * lib/autotest/general.m4 (_AT_CREATE_DEBUGGING_SCRIPT): New
10766 macro, split out from...
10767 (AT_INIT): ...here, so that using -d also generates a run script.
10768 Document that -d inhibits top-level logging.
10769 * doc/autoconf.texi (testsuite Invocation): Document that -d only
10770 inhibits top-level logging; debug scripts are created.
10772 * lib/autotest/general.m4 (_AT_CHECK): Avoid syntax error on empty
10774 * tests/autotest.at (Empty test, Empty check): New test to check it.
10776 * lib/autoconf/c.m4 (AC_C_CONST, AC_C_VOLATILE): Avoid warnings
10779 2006-04-10 Stepan Kasal <kasal@ucw.cz>
10781 * tests/mktests.sh: Use "trap '' 0", not "trap 0". Do not touch
10782 the files if a problem appears. Make the empty *.at files
10783 read-only, too. Proposed by Ralf Wildenhues.
10785 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10787 * config/Makefile.am: Add comment to force updated Makefile.in.
10789 * lib/freeze.mk: Fix typo in comment. Unlike the last, white
10790 space only patch to this file, this patch causes the Makefile.in
10791 files that include freeze.mk to be updated, and thus have a
10792 newer time stamp again, which in turn makes a pristine CVS
10793 checkout have correct time stamps.
10795 * Makefile.maint (cvs-sv): New macro, to be used..
10796 (config.guess-url_prefix, config.sub-url_prefix)
10797 (texinfo.tex-url_prefix, standards.texi-url_prefix): ..here;
10798 point to CVS text checkout of Gnulib files.
10799 (copyright-check): Bump current year.
10800 (announcement): Do not hard-wire `./announce-gen'.
10801 (cvs-update): Propagate failures of `cvs' and `move-if-change'
10803 * Makefile.cfg (executable-update): Use `chmod a+x' instead of
10805 (wget_files): Update config.guess, config.sub, texinfo.tex by
10806 `wget-update', now that their URLs work again.
10808 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
10810 * doc/autoconf.texi (Particular Types): Don't use AC_CHECK_TYPE.
10811 Problem noted by Paul D. Smith.
10813 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10815 * doc/autoconf.texi: Remove unused words from word list.
10816 * .x-sc_prohibit_atoi_atof, .x-sc_space_tab, .x-sc_sun_os_names,
10817 .x-sc_trailing_space: New files.
10819 * doc/standards.texi: Sync from gnulib.
10821 * NEWS, doc/autoconf.texi (AC_LIBOBJ vs LIBOBJS): Mark
10822 `LIBOBJDIR' as experimental.
10824 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): MSYS `ln -s' fails
10825 with a target directory; it's internally implemented as `cp'
10826 anyway, but since Autoconf advertises the possibility to use
10827 a target directory when LN_S is `ln -s', we need to find out.
10828 Reported by Rolf Ebert <rolf.ebert.gcc@gmx.de> against MSYS,
10829 analyzed by Keith Marshall <keith.marshall@total.com>.
10833 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
10835 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Just output
10836 confdefs.h as-is. In general, if it has backslash-newline or the
10837 like, then it doesn't work either to sort or to remove empty
10840 2006-04-09 Stepan Kasal <kasal@ucw.cz>
10842 * tests/Makefile.am (AUTOCONF_FILES): Fix typo in the comment.
10844 2006-04-09 Alexandre Duret-Lutz <adl@gnu.org>
10846 * lib/autom4te.in (Automake-preselections): Preselect
10849 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>
10851 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Use '\'' for an
10852 apostrophe within a single-quoted string, as this is the usual
10853 tradition and is easier to read than '"'"'. Don't rely on the
10854 shell treating "$/" like '$/'. Use a more-consistent indenting
10855 style for the trap.
10857 2006-04-09 Eric Blake <ebb9@byu.net>
10859 * tests/autotest.at (Backquote command substitution),
10860 (Multiline backquote command substitution): Remove mistaken
10861 AT_NO_CMDSUBST from the 2006-03-14 patch, which was meant to be
10863 (Parenthetical command substitution, Multiline parenthetical
10864 command substitution): here.
10866 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>
10868 Import macros from gnulib (often changing their name).
10870 * NEWS: AC_C_TYPE_LONG_DOUBLE is now obsolete.

10889 (Generic Headers): Add AC_CHECK_HEADERS_ONCE.
10890 (Generic Declarations): Add AC_CHECK_DECLS_ONCE.
10891 (Particular Structures): Add AC_STRUCT_DIRENT_D_INO,

10895 Add AC_TYPE_INT8_T, AC_TYPE_INT16_T, AC_TYPE_INT32_T, AC_TYPE_INT64_T,
10896 AC_TYPE_INTMAX_T, AC_TYPE_INTPTR_T, AC_TYPE_LONG_DOUBLE,
10897 AC_TYPE_LONG_DOUBLE_WIDER, AC_TYPE_LONG_LONG_INT, AC_TYPE_UINT8_T,
10898 AC_TYPE_UINT16_T, AC_TYPE_UINT32_T, AC_TYPE_UINT64_T,
10899 AC_TYPE_UINTMAX_T, AC_TYPE_UINTPTR_T, AC_TYPE_UNSIGNED_LONG_LONG_INT.
10900 (C Compiler): Move AC_C_LONG_DOUBLE to ...
10901 (Obsolete Macros): here. Under AC_LONG_DOUBLE, mention
10902 AC_TYPE_LONG_DOUBLE or AC_TYPE_LONG_DOUBLE_WIDER instead.
10903 (Posix Variants): Add AC_USE_SYSTEM_EXTENSIONS.
10904 (Coding Style). Don't mention m4_expand_once.
10905 * lib/autoconf/c.m4 (AC_C_LONG_DOUBLE): Implement via

10913 (AC_HEADER_ASSERT): New macro.
10914 (AC_HEADER_STDBOOL): Don't assume "#error" works.
10915 Catch a bug in IBM AIX xlc compiler version 6.0.0.0.
10916 Catch a bug in an HP-UX C compiler.
10917 * lib/autoconf/specific.m4 (AC_USE_SYSTEM_EXTENSIONS): New macro.
10918 * lib/autoconf/types.m4 (AC_TYPE_INTMAX_T. AC_TYPE_UINTMAX_T):

10925 * tests/mktests.sh (ac_exclude_list, au_exclude_list): Do not
10926 use /^foo|bar$/, it does not mean /^(foo|bar)$/.
10928 2006-04-08 Stepan Kasal <kasal@ucw.cz>
10930 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Fix the wording
10931 of the warning introduced by the 2001-08-28 change.
10933 2006-04-08 Stepan Kasal <kasal@ucw.cz>,
10934 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10936 * lib/autoconf/general.m4 (AC_CACHE_SAVE): All `ac_cv_env_foo'
10937 variables shall be overriden by the cache.
10938 * tests/torture.at (AC_ARG_VAR): Test also with a first value
10939 that contains braces.
10941 2006-04-07 Stepan Kasal <kasal@ucw.cz>
10943 Revert the patch from 2006-04-01 and only improve
10944 _AS_DETECT_BETTER_SHELL:
10946 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Do not optimize; do not
10947 skip nonexistent directories.
10948 (_AS_DETECT_BETTER_SHELL): The optimization is moved here--try
10949 only shell candidates which exist.
10950 (AS_UNAME): No need to give three parameters to _AS_PATH_WALK.
10951 * lib/autotest/general.m4 (AT_INIT): No need to give three
10952 parameters to _AS_PATH_WALK.
10954 2006-04-07 Stepan Kasal <kasal@ucw.cz>,
10955 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10957 * bin/autoupdate.in (handle_autoconf_patches): Change the way we
10958 distinguish m4sugar macros.
10959 * tests/tools.at (autoupdating with aclocal and m4_include):
10960 New test. Bug reported by Gary V. Vaughan <gary@gnu.org>,
10961 test case by Noah Misch <noah@cs.caltech.edu>.
10963 2006-04-07 Stepan Kasal <kasal@ucw.cz>
10965 Revert my change from 2006-03-17, in other words:
10966 * lib/m4sugar/m4sh.m4 (AS_BOURNE_COMPATIBLE): Insert BIN_SH=xpg4
10968 (AS_SHELL_SANITIZE): Remove DUALCASE=1.
10969 * doc/autoconf.texi (Special Shell Variables) <BIN_SH>: Say that
10972 2006-04-07 Eric Blake <ebb9@byu.net>
10974 * doc/autoconf.texi (Programming in M4sh): Document that
10975 AS_MKDIR_P exits the script on failure.
10976 * lib/autotest/general.m4: Remove redundant AS_ERROR.
10978 2006-04-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10980 * config/elisp-comp, config/install-sh, config/mdate-sh,
10981 config/missing, config/mkinstalldirs: Sync from Automake.
10983 * lib/Autom4te/FileUtils.pm, lib/Autom4te/Struct.pm: Sync
10986 * doc/make-stds.texi: Sync from gnulib.
10988 2006-04-06 Eric Blake <ebb9@byu.net>
10990 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_O): Inside cache
10991 check, s/ac_exeext/ac_cv_exeext/. Fixes regression introduced
10994 2006-04-06 Stepan Kasal <kasal@ucw.cz>,
10995 Eric Blake <ebb9@byu.net>,
10996 Paul Eggert <eggert@cs.ucla.edu>,
10997 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10999 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): Fix the detection of
11000 whether `set' quotes correctly: redirect stderr of the tested
11001 `set', and use a subshell, for Ultrix; use `sed' instead of
11002 `grep' for zsh `set' which may write binary output; match only
11003 at the beginning of a line, to avoid false positives.
11004 In order to avoid false positives by unrelated variables with
11005 multiline content, put the dump algorithm in a subshell and
11006 unset all variables containing newlines (except some which are
11007 special to the shell). Warn about cache variables that are
11010 2006-04-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11012 * config/config.guess, config/config.sub, config/texinfo.tex:
11013 Sync from upstream.
11015 * tests/mktests.sh: Reword comments.
11017 * tests/mktests.sh: Only skip internal macros starting with
11018 `_AC_' or `__AC_'. Noted by Stepan Kasal.
11019 Update exclusion lists for the test suite to this end:
11020 (AC_ARG_VAR): Do test this now.
11021 (AC_SEARCH_LIBS, AC_REPLACE_FUNCS): Need an argument.
11022 (AC_LINKER_OPTION): Remove (renamed to _AC_LINKER_OPTION).
11023 (AC_LIST_MEMBER_OF): Likewise (renamed to _AC_LIST_MEMBER_IF).
11024 (AC_LINK_FILES): Obsoleted since (and thus AU_DEFUN'ed).
11026 * doc/autoconf.texi (Shell Substitutions): Mention the MSYS
11027 shell issue with double-quoted command substitutions of native
11029 Reported to MSYS by Mark Cave-Ayland, to Autoconf by Keith
11032 * Makefile.maint (sc_cast_of_argument_to_free): Do not fail when

11040 (sc_tight_scope): Do not fail for non-existing `src' directory.
11041 (sc_changelog): Skip the Copyright footer.
11042 * lib/autoconf/lang.m4: Remove trailing space.
11044 * lib/autoconf/status.m4: More replacements to
11045 <tab><space> where this makes sense.
11047 2006-04-06 Stepan Kasal <kasal@ucw.cz>
11049 * tests/Makefile.am (maintainer-check-posix):
11050 s/POSIXLY_CORRECTLY/POSIXLY_CORRECT/
11052 * lib/autoconf/status.m4 (_AC_CONFIG_FOOS): Append TAGS to
11053 ac_config_<foo>s again, sometimes normalized, sometimes not.
11054 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_LINKS):
11055 (AC_CONFIG_COMMANDS): Do not do so here.
11056 (_AC_CONFIG_REGISTER_DEST): Double quote the tags in macros _AC_LIST_TAGS
11057 and_AC_LIST_TAG_COMMANDS; fixes another regression introduced by the
11058 2005-07-25 rewrite. Noticed by Noah Misch.
11060 * lib/autoconf/general.m4 (AC_PRESERVE_HELP_ORDER): Do not define
11061 _AC_PRESERVE_HELP_ORDER, ...
11062 (AC_ARG_ENABLE, AC_ARG_WITH): ... use AC_PROVIDE_IFELSE insetad.
11064 * lib/autoconf/general.m4 (AC_ARG_VAR): Do not use m4_divert_once
11065 inside m4_expand_once; it is redundant.
11067 * lib/autoconf/general.m4 (_AC_INIT_HELP): Remove the broken support
11068 for --help from Cygnus `configure.'
11070 2006-04-06 Paul Eggert <eggert@cs.ucla.edu>
11072 * doc/autoconf.texi (C Compiler): Warn about #error. Follows up
11073 on a patch proposed by Ralf Wildenhues.
11075 2006-04-05 Paul Eggert <eggert@cs.ucla.edu>
11077 * lib/autoconf/status.m4: Replace <space>''<tab> with
11078 <tab><space> where this makes sense.
11080 2006-04-05 Howard Chu <hyc@highlandsun.com> (trivial change)
11081 Noah Misch <noah@cs.caltech.edu>
11083 * lib/autoconf/general.m4 (AC_PRESERVE_HELP_ORDER): New macro.
11084 (AC_ARG_ENABLE, AC_ARG_WITH): Adjust.
11085 * doc/autoconf.texi (Help Formatting): New node.
11086 * NEWS: Announce AC_PRESERVE_HELP_ORDER.
11088 2006-04-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11090 * TODO, config/Makefile.am, lib/freeze.mk, lib/autoconf/c.m4,
11091 lib/autoconf/specific.m4, lib/autoconf/status.m4,
11092 lib/autoconf/types.m4, lib/autotest/general.m4,
11093 tests/mktests.sh, tests/torture.at: White space cleanup:
11094 remove some SPACE before TAB, or add quoting ('' or @&t@).
11096 * NEWS, TODO, bin/autoreconf.in: `filesystem' -> `file system'.
11098 * doc/autoconf.texi (Shell Substitutions): Document `^' vs. `|'.
11100 2006-04-05 Eric Blake <ebb9@byu.net>
11102 * lib/autotest/general.m4 (AT_INIT): Prep AT_*_all, so that an
11103 empty test suite works.
11104 * tests/autotest.at (Empty test suite): Remove xfail.
11106 2006-04-05 Noah Misch <noah@cs.caltech.edu>
11108 * lib/autoconf/status.m4 (_AC_CONFIG_FOOS): Do not append normalized
11109 TAGS to ac_config_<foo>s.
11110 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_LINKS): Do so here.
11111 (AC_CONFIG_COMMANDS): Append NAME to ac_config_commands without
11112 normalizing it, consistent it with previous releases.
11113 * tests/torture.at (Macro calls in AC_CONFIG_COMMANDS tags): New test.
11115 2006-04-05 Paul Eggert <eggert@cs.ucla.edu>
11117 * lib/m4sugar/m4sh.m4 (AS_BASENAME_EXPR, AS_DIRNAME_EXPR):
11118 Use simplified args that Eric Blake originally suggested.
11120 2006-04-04 Paul Eggert <eggert@cs.ucla.edu>
11122 * tests/mktests.sh: Don't use 'cat'; just read the files directly.
11123 Prefer 'sort -u' to 'sort | uniq'. Filter data before sorting it.
11124 Use 'comm' rather than N instances of grep; this also fixes a bug
11125 whereby substrings were incorrectly matched, causing us to not

11127 (exclude_list): Exclude empty macros.
11128 (ac_exclude_list): Exclude AC_INCLUDES_DEFAULT.

11133 Switch from grep to awk syntax.
11134 (ac_exclude_script): Renamed from ac_exclude_egrep.

11561 newline for portability.
11562 * tests/torture.at (Torturing config.status): Also test 100

12034 in case the computer is too quick. Double quote the configure.ac
12037 * tests/local.at (AT_CHECK_AUTOCONF): Always pass --force to prevent
12038 problems if the testsuite were running too fast.
12040 2005-09-18 Paul Eggert <eggert@cs.ucla.edu>
12042 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Look for X11/Xlib.h
12043 and XrmInitialize rather than X11/Intrinsic.h and XtMalloc
12044 (which belong to Xt, not X itself). See Debian bug 327655.
12045 * NEWS: Mention this.
12047 2005-09-07 Stepan Kasal <kasal@ucw.cz>
12049 * lib/autoconf/c.m4 (AC_LANG_SOURCE(C)): Remove an incorrect comment.
12051 2005-09-06 Paul Eggert <eggert@cs.ucla.edu>
12053 * config/move-if-change: Don't output "$2 is unchanged";
12054 suggested by Ben Elliston. Handle weird characters correctly.
12056 2005-09-06 Stepan Kasal <kasal@ucw.cz>
12058 * lib/autoconf/libs.m4 (AC_SEARCH_LIBS): Merge the two AC_LINK_IFELSE
12059 calls, so that the final expansion of this macro is shorter.
12060 Create the conftest.$ac_ext outside the `for' loop, to speed the run.
12061 Do not use `break' in the argument to AC_LINK_IFELSE, it would skip
12062 the cleanup there. Use AS_VAR_* macros, to be more general.
12063 * tests/semantics.at (AC_SEARCH_LIBS): Check for the cleanup.
12065 * lib/autoconf/general.m4: Use AS_IF where appropriate.
12067 * lib/m4sugar/m4sh.m4 (AS_IF): Use m4_default.
12069 2005-09-01 Stepan Kasal <kasal@ucw.cz>
12071 * doc/autoconf.texi (Configuration Headers): Add an index entry
12074 2005-08-26 Pavel Roskin <proski@gnu.org>
12076 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): Use shell variable
12077 XMKMF to locate xmkmf. Make XMKMF precious. Export CC when
12080 2005-08-26 Paul Eggert <eggert@cs.ucla.edu>
12082 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE):
12083 The previous patch didn't work, so try a better one.
12085 2005-08-26 Stepan Kasal <kasal@ucw.cz>
12087 * doc/autoconf.texi (Programming in M4sh) <AS_TR_CPP>: Fix m4 quoting
12088 in the example. Reported by Bruno Haible.
12089 <AS_TR_SH>: Likewise. Also modify the example to be more convincing:
12090 "if $undefined_var;" succeeds with my shell.
12092 * lib/autoconf/general.m4 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST,
12093 AC_CANONICAL_TARGET): Define by AC_DEFUN, no need to use AC_DEFUN_ONCE;
12094 but change the m4_divert_text to m4_divert_once.
12096 2005-08-25 Paul Eggert <eggert@cs.ucla.edu>
12098 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE):
12099 Work around bug in Solaris /usr/xpg4/bin/awk.
12100 The bug is present in at least Solaris 8 through 10.
12102 2005-08-24 Stepan Kasal <kasal@ucw.cz>
12104 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Simplify; rejecting
12105 some evil values and relying on the fact that $* concatenates the
12106 parameters by the first character from IFS.
12108 2005-08-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
12109 Stepan Kasal <kasal@ucw.cz>
12111 * lib/autoconf/status.m4 (_AC_CONFIG_REGISTER_DEST): When the
12112 first header appears, define AH_HEADER.
12113 * doc/autoconf.texi (Configuration Headers): Document AH_HEADER.
12114 Update limitations about when to call AC_CONFIG_HEADERS.
12115 (Configuration Commands): Document that AC_CONFIG_COMMANDS_PRE
12116 parameter can call AC_SUBST, AC_DEFINE, or AC_CONFIG_FOOS; explain
12117 that AC_CONFIG_COMMANDS_PRE and AC_CONFIG_COMMANDS_POST are not
12118 ``Configuration Actions''; fix their index entries.
12120 * lib/autotest/general.m4 (AT_INIT): Process multiple keywords
12121 options correctly. Process N-M as M-N if M is smaller than N.
12122 Process ranges correctly so that N-N will run only N.
12123 Sort and uniquify the tests that will be run. If there is more
12124 than one test, reinsert the banners for the tests.
12125 * tests/autotest.at (Keywords): Unmark XFAIL.
12127 2005-08-23 Stepan Kasal <kasal@ucw.cz>
12129 * lib/autoconf/general.m4 (_AC_DEFINE_Q): Strip the parameter list
12130 before passing the macro name to AH_TEMPLATE.
12132 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): config.status
12133 now opens log after option processing; in particular, --version
12134 and --help do not touch config.log.
12136 * Makefile.maint: Revert the change from 2005-08-12.
12138 2005-08-22 Stepan Kasal <kasal@ucw.cz>
12140 * lib/autoconf/general.m4 (AC_ARG_ENABLE, AC_ARG_WITH): Factor out
12142 (_AC_ENABLE_IF, _AC_ENABLE_IF_ACTION): ... these new macros.

12146 * doc/autoconf.texi (Using Autotest, testsuite Scripts)
12147 (Autotest Logs, Writing testsuite.at, testsuite Invocation):
12150 * doc/autoconf.texi (Defining Symbols, Changed Results):
12151 Prepend to LIBS, not append, in examples.
12153 2005-08-16 Stepan Kasal <kasal@ucw.cz>
12155 When building in place, set srcdir="."; suggested by Tim Van Holder.
12157 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Do this; to recognize
12158 build in place, we need ac_pwd, and thus have to AC_REQUIRE ...
12159 (_AC_INIT_DIRCHECK): ... this macro and AC_DEFUN both of them.
12160 * lib/autoconf/status.m4 (_AC_SRCDIRS): Fix a comment: srcdir="."
12161 does not mean "no --srcdir option".
12163 2005-08-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
12165 * tests/autoscan.at (autoscan): New file.
12166 * tests/suite.at: Use it.
12167 * tests/Makefile.am (TESTSUITE_HAND_AT): Add it.
12168 Reported against Libtool by Gideon Go <gideon.go@gmail.com>.
12170 * tests/autotest.at (Keywords): Test keywords combinations.
12172 2005-08-12 Stepan Kasal <kasal@ucw.cz>
12174 * Makefile.maint (GZIP_ENV): When checking the help text of gzip,
12175 add "2>&1"; gzip 1.2.4 prints help on stderr.
12177 2005-07-27 Stepan Kasal <kasal@ucw.cz>
12179 * lib/autotest/general.m4 (_AT_DECIDE_TRACEABLE): The symbol at_reason
12180 was pushdef'ed twice while popped only once. Push it only once.
12181 (_AT_CHECK): Cosmetic changes to the "case $at_status" command.
12183 2005-07-26 Stepan Kasal <kasal@ucw.cz>
12185 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): The message is now

12188 2005-07-25 Paul Eggert <eggert@cs.ucla.edu>
12190 * Makefile.maint: Update from Bison.
12192 * lib/m4sugar/m4sugar.m4 (m4_strip): Comment fix---change tab to
12193 "<tab>" in comment, so that the point is understandable.
12195 2005-07-25 Stepan Kasal <kasal@ucw.cz>
12197 Rewrite substantial part of lib/autoconf/status.m4.
12198 The main change is that CONFIG_FILES, CONFIG_HEADERS, CONFIG_LINKS,
12199 and CONFIG_COMMANDS are not processed in four separate loops.
12200 Instead, there is one main loop. This alows that the common code
12201 is expanded only once, thus config.status (and configure) is smaller.
12203 The registration mechnism in AC_CONFIG_FILES and cousins also changed;
12204 the AC_LIST_FILES and cousins macros are no longer used.
12206 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES, _AC_OUTPUT_HEADERS,
12207 _AC_OUTPUT_LINKS, _AC_OUTPUT_COMMANDS): Renamed to ...
12208 (_AC_OUTPUT_FILE, _AC_OUTPUT_HEADER, _AC_OUTPUT_LINK,
12209 _AC_OUTPUT_COMMAND): ..., respectively. These macros no longer
12210 contain the initialization, nor the for loop, nor the associated
12211 commands; all these go to ...
12212 (_AC_OUTPUT_MAIN_LOOP): ... this new macro, called from
12213 _AC_OUTPUT_CONFIG_STATUS.
12214 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST, _AC_CONFIG_SPLIT_FILE_IN):
12215 Nuked; the code was merged into _AC_OUTPUT_MAIN_LOOP.
12216 (_AC_OUTPUT_FILE): The creation of the sed script ...
12217 (AC_OUTPUT): ... and the setup of ac_vpsub goes to ...
12218 (_AC_OUTPUT_FILES_PREPARE): ... a new macro, also called from
12219 _AC_OUTPUT_MAIN_LOOP.
12220 (_AC_CONFIG_FILES, _AC_CONFIG_HEADERS, _AC_CONFIG_LINKS,
12221 _AC_CONFIG_COMMANDS): Use ...
12222 (_AC_CONFIG_FOOS): ... this new macro, which uses these ...
12223 (_AC_CONFIG_REGISTER, _AC_CONFIG_REGISTER_DEST): ... new macros.
12224 (_AC_CONFIG_FILE, _AC_CONFIG_HEADER, _AC_CONFIG_LINK,
12225 _AC_CONFIG_COMMAND, _AC_CONFIG_DEPENDENCIES): No longer needed.
12226 (_AC_CONFIG_DEPENDENCY): Update, it uses these ...
12227 (_AC_CONFIG_DEPENDENCY_DEFAULT, _AC_FILE_DEPENDENCY_TRACE_COLON):
12229 (_AC_CONFIG_UNIQUE): Update.
12230 (AC_LIST_FILES, AC_LIST_HEADERS, AC_LIST_LINKS, AC_LIST_COMMANDS):
12231 Replaced by this ...
12232 (_AC_LIST_TAGS): ... new common macro.
12233 (AC_LIST_FILE_COMMANDS, AC_LIST_HEADER_COMMANDS, AC_LIST_LINK_COMMANDS,
12234 AC_LIST_COMMAND_COMMANDS): Replaced by this ...
12235 (_AC_LIST_TAG_COMMANDS): ... new common macro.
12236 (_AC_CONFIG_COMMANDS_INIT): Moved top to the `registration' section;
12237 this didn't belong to the `config commands' section.
12238 (_AC_OUTPUT_COMMANDS_INIT): Don't initialize, m4_ifdef is our friend.
12239 (AC_CONFIG_COMMANDS_PRE, AC_OUTPUT_COMMANDS_PRE,
12240 AC_CONFIG_COMMANDS_POST): Moved to a new section, these didn't belong
12241 to the `config commands' section either.
12242 (AC_CONFIG_SUBDIRS): Don't touch diversion DEFAULTS.
12243 (_AC_LIST_SUBDIRS): Don't initialize, m4_ifdef is our friend.
12245 ... and many changes to the comments nearby.
12247 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): At the end of the day,
12248 set ac_subdirs_all='_AC_LIST_SUBDIRS'.
12249 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
12250 AC_CONFIG_COMMANDS(command:input,...) is no longer allowed.
12251 (#define header templates): The comment at the top of the generated
12252 header now includes the name(s) of the source file(s).
12254 Several unrelated small changes:
12256 * lib/autoconf/general.m4 (AC_CACHE_VAL): Be didactic, quote the first
12257 parameter to AC_DIAGNOSE.
12258 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS): Likewise.
12259 (_AC_LINK_FILES_CNT): Don't AU_DEFUN this; it causes confusing messages
12260 with autoupdate; use m4_define_default inside AU_DEFUNed AC_LINK_FILES.
12261 (AC_OUTPUT): In the compatibility code, use m4_ifvaln, to be consistent
12262 with AU::AC_OUTPUT.
12263 (AU::AC_OUTPUT): Don't double-quote $2 and $3, the compatibility code
12264 in AC_OUTPUT doesn't double-quote it either.
12265 * tests/tools.at (autoupdate): AU::AC_OUTPUT no longer double-quotes the
12268 2005-07-10 Stepan Kasal <kasal@ucw.cz>
12270 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Document which
12271 versions of Portland Group compiler produce single- and double-quoted
12272 -cmdline argument. Reported by Steven G. Johnson <stevenj@fftw.org>
12273 and Ole Holm Nielsen <Ole.H.Nielsen@fysik.dtu.dk>.
12275 2005-07-07 Paul Eggert <eggert@cs.ucla.edu>
12277 * tests/local.at (AT_CONFIG_CMP): Ignore lines like "LIBS=''" too.
12278 This is a corrected version of yesterday's patch.
12280 2005-07-07 Stepan Kasal <kasal@ucw.cz>
12282 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Report the full
12283 path, too; insert a "===" to emphasize the line.
12285 * lib/autoconf/general.m4 (AC_CANONICAL_BUILD): Rename
12286 ac_cv_build_alias to ac_build_alias.
12287 (AC_CANONICAL_HOST, AC_CANONICAL_TARGET): Simplify.
12289 On 2005-02-24, an unintentional AC_SUBST([CC]) was introduced; this
12290 change eliminates it. Problem reported by Alexandre Duret-Lutz.
12291 * lib/autoconf/general.m4 (_AC_ARG_VAR_PRECIOUS): Move the AC_SUBST ...
12292 (AC_ARG_VAR): ... here.
12293 (_AC_INIT_PREPARE): Call AC_SUBST for build_alias, host_alias and
12296 Keep a list of all precious variables and process them with one simple
12297 for loop, instead of expanding all commands, or, OTOH, complicated
12298 processing of output of "set".
12299 * lib/autoconf/general.m4 (_AC_ARG_VAR_PRECIOUS): Acumulate the
12300 variable names in new macro...
12301 (_AC_PRECIOUS_VARS): ... which will be assigned to ac_precious_vars.
12302 (_AC_ARG_VAR_STORE): New macro which writes to diversion PARSE_ARGS
12303 a loop to assign all ac_env_* and ac_cv_env_* variables.
12304 (_AC_ARG_VAR_VALIDATE): Use shell variable ac_precious_vars, divert
12306 (_AC_INIT_DEFAULTS): At the end, if _AC_PRECIOUS_VARS is set, assign
12307 its value to shell variable ac_precious_vars and call
12308 _AC_ARG_VAR_STORE and _AC_ARG_VAR_VALIDATE.
12309 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Don't call
12310 _AC_ARG_VAR_VALIDATE.
12312 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Move AC_LANG_PUSH(C)
12313 and the AC_SUBSTs ...

12317 the ac_subst_files section in config.log.

12321 2005-07-06 Paul Eggert <eggert@cs.ucla.edu>
12323 * NEWS: New macro AC_C_TYPEOF.
12324 * doc/autoconf.texi (C Compiler): Document AC_C_TYPEOF.
12325 * lib/autoconf/c.m4 (AC_C_TYPEOF): New macro.
12326 * tests/c.at (C keywords): Test AC_C_TYPEOF.
12328 Fix problems reported by Nicolas Joly.

12331 They are generated by the Tru64 v5.1B shell.
12333 2005-07-05 Stepan Kasal <kasal@ucw.cz>
12335 Fix my changes from 2005-07-01; reported by Noah Misch.
12336 * lib/autoconf/status.m4 (_AC_CONFIG_DEPENDENCIES): Fix the
12337 description, the macro now accepts only a single tag.
12338 (_AC_CONFIG_UNIQUE): Likewise; s/AC_File/[$1]/
12340 Fix cases when the varsions of Autoconf and Autotest don't match.
12341 Reported by Noah Misch.
12342 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Set also
12343 at_top_builddir, for compatibility with older autotest.
12344 * lib/autotest/general.m4 (AT_INIT): If at_top_build_prefix
12345 is not set, use at_top_builddir, for compatibility with older
12346 versions of autoconf.
12348 2005-07-04 Paul Eggert <eggert@cs.ucla.edu>
12350 * bin/autom4te.in ($m4): Catch usages like --nesting-limit=2048.
12351 Problem reported by Patrick Welche.
12353 2005-07-03 Paul Eggert <eggert@cs.ucla.edu>
12355 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Use &, not |, in
12356 sed substitution command, so that we allow | in program prefixes
12357 and program suffixes. (& is a problem anyway; we're not fixing
12359 * lib/autoconf/status.m4 (AC_CONFIG_FILES): Likewise, for
12360 configure_input, top_builddir, srcdir, etc.
12361 * lib/autotest/general.m4 (AT_INIT): Likewise, for
12362 PATH_SEPARATOR in AUTOTEST_PATH.
12364 2005-07-02 Alexandre Duret-Lutz <adl@gnu.org>
12366 * lib/autoconf/general.m4 (AC_SITE_LOAD): Rewrite the
12367 for loop over config.site files using `set', to allow
12368 directory names containing IFS characters.
12370 2005-07-01 Paul Eggert <eggert@cs.ucla.edu>
12372 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Remove the tests for
12373 directories with weird names. Apparently some people like living
12374 on the edge. However, improve the test that "pwd" actually does
12375 report a name for the working directory.
12376 * NEWS: Remove the claim that we test for funny chars in dir names.
12378 2005-07-01 Stepan Kasal <kasal@ucw.cz>
12380 * lib/autoconf/general.m4 (AC_FOREACH): Make obsolete; it's
12382 * lib/m4sugar/m4sugar.m4 (m4_foreach_w): ... by this new macro.
12383 * lib/autoconf/status.m4 (_AC_CONFIG_DEPENDENCIES, _AC_CONFIG_UNIQUE):

12390 about #include <config.h>.
12391 (Generic Functions): Mention the Gnulib project.
12392 (Limitations of Usual Tools) <sed>: Another minor rephrasing.
12394 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Use a here
12395 document to output the default config_* lists to config.status.
12396 Don't recognize option --file, if the functionality is not there.
12397 Likewise for --header; moreover, recognize --he and --h as shortcuts
12398 for --help in that case.
12400 * lib/autoconf/status.m4: Fix the order of the "sections", so that it
12401 matches the order of execution. No code changed.
12403 2005-06-30 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
12405 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Fix also for
12406 single-quoted -cmdline argument in Portland Group compiler.
12407 Reported against LAM by Ole Holm Nielsen <Ole.H.Nielsen@fysik.dtu.dk>.
12409 2005-06-30 Alexandre Duret-Lutz <adl@gnu.org>
12411 * lib/autom4te.in (Automake-preselections): Preselect AC_SUBST_TRACE.
12413 2005-06-29 Stepan Kasal <kasal@ucw.cz>
12415 * doc/autoconf.texi (File Descriptors): ksh doesn't pass open file
12416 descriptors to child processes; reported by Norman Gray.
12418 2005-06-29 Stepan Kasal <kasal@ucw.cz>
12420 * lib/autoconf/general.m4 (AC_ARG_VAR): Move next to _AC_ARG_PRECIOUS.
12422 * lib/autoconf/general.m4 (AC_SUBST_TRACE): New macro, to be traced
12423 instead of AC_SUBST; proposed by Alexandre Duret-Lutz.
12424 (AC_SUBST): Call it.
12425 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Call AC_SUBST_TRACE for
12426 the directory specific variables; but don't call it for configure_input.
12428 2005-06-28 Derek Price <derek@ximbiot.com>
12430 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: Reword recent
12433 2005-06-23 Paul Eggert <eggert@cs.ucla.edu>
12435 * NEWS: Don't worry about spaces in bindir etc. Only srcdir and working
12436 directory have inherent problems with special characters like spaces,
12437 due to limitations in Make syntax. Problem reported by Alexandre
12439 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Implement the above.
12440 Also, fix Tru64 porting problem with shell patterns,
12441 reported by Ralf Wildenhues.

12451 Fix some more shell quoting problems. Prompted by a bug report
12452 from Justace Clutter.
12453 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Put name of invalid
12454 variable into diagnostic. Make the diagnostic an error, not a warning,
12455 because we really don't support spaces and suchlike in dir names.
12456 (_AC_INIT_SRCDIR): Allow special characters in $ac_unique_file.
12457 Don't worry about backslashes in srcdir; it can't happen now.
12458 (_AC_INIT_PARSE_ARGS): Allow weird characters in ac_optarg.
12459 Simplify ac_optarg handling.
12460 (_AC_ARG_VAR_VALIDATE): Remove unnecessary and inconsistent quotes.

12468 (AT_CONFIG_CMP): Use sed instead of grep plumbing.
12470 * doc/autoconf.texi (Limitations of Usual Tools) <grep>: Mention
12471 that '\|' is not allowed in BREs; recommend using newline separated
12472 list of patterns instead of multiple -e options.

12480 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Fix typo.
12482 2005-06-21 Stepan Kasal <kasal@ucw.cz>
12484 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: Document that
12485 b, t, r, w commands require single space, while : cannot have any.
12486 (Special Shell Variables): Fix sed code this in the example.
12487 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Likewise; and fix a typo.
12488 * lib/autotest/general.m4 (AT_ARG_OPTION): Fix typo in the description.
12490 * lib/m4sugar/m4sugar.m4 (m4_split): If the parameter is empty,
12491 expand to the empty list. Don't use two pairs of m4_changequote,
12492 it's not necessary.
12494 2005-06-20 Derek Price <derek@ximbiot.com>
12496 * lib/m4/programs.m4 (AC_PROG_YACC): Declare YACC & YFLAGS precious.
12498 2005-06-17 Paul Eggert <eggert@cs.ucla.edu>
12500 * lib/m4sugar/m4sh.m4 (as_awk_strverscmp): Port to Solaris /bin/awk.
12501 * doc/autoconf.texi:
12502 Don't mention Solaris versions so much, if a
12503 problem is common to all extant versions of Solaris. Say "SunOS
12504 4" instead of "SunOS" for SunOS 4.
12505 (awk): Mention more of the limitations of traditional Awk.
12506 (cat): Don't talk about cat -v.
12508 2005-06-16 Paul Eggert <eggert@cs.ucla.edu>
12510 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE): New macro.
12511 (AS_VERSION_COMPARE): New macro. The API is taken from CVS,
12512 but the implementation is entirely different and is designed
12513 to be compatible with glibc strverscmp.
12514 * tests/m4sh.at (AS_VERSION_COMPARE): New test.
12516 * doc/autoconf.texi (Limitations of Usual Tools): Mention expr bug
12517 on Mac OS X 10.4 reported by Peter O'Gorman in:
12518 http://lists.gnu.org/archive/html/autoconf-patches/2005-06/msg00041.html
12519 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT):
12520 Use shell builtins rather than 'expr', to work around expr bug.
12522 2005-06-10 Paul Eggert <eggert@cs.ucla.edu>
12524 * doc/autoconf.texi: "filesystem" -> "file system".
12525 "behaviour" -> "behavior".

12527 * lib/autoconf/general.m4: Omit blank after ":" sed command,
12529 * lib/m4sugar/m4sh.m4: Likewise.
12530 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Work around problem
12531 with Solaris sed. Fix by Ralf Menzel and Stepan Kasal.
12533 * man/Makefile.am (MOSTLYCLEANFILES): Add $(srcdir)/*.t.
12534 (.x.1): Ignore the time stamp in the .TH line when deciding whether
12535 to update the man page. That way, we don't have to check in new
12536 man pages every month.
12538 * lib/m4sugar/m4sh.m4 (AS_VAR_TEST_SET): Work even if $1 contains
12539 quotes and backslashes. Patch from Derek Price.

12548 * lib/autotest/general.m4 (AT_INIT): Don't accept Solaris 9's diff
12549 -u, since it outputs chatter if the input files are the same.
12550 Problem reported by Ralf Menzel.
12552 2005-06-08 Derek Price <derek@ximbiot.com>
12554 * lib/m4sugar/m4sugar.m4: Undefine include & sinclude rather than
12555 renaming them since they are about to be redefined anyhow.
12557 2005-06-08 Derek Price <derek@ximbiot.com>
12559 * doc/autoconf.texi (Redefined M4 Macros): Add index entries for most
12560 redefined M4 macros to this node. Document m4_include & m4_sinclude.
12561 Move m4_undefine to alphabetical order.
12563 2005-06-07 Paul Eggert <eggert@cs.ucla.edu>
12565 * README: Recommend GNU M4 1.4.3 or later.
12566 * doc/autoconf.texi (Introduction): Likewise.
12567 Reword to avoid some formatting glitches.
12568 Use "#!/bin/sh", not "#! /bin/sh"; the space isn't needed these days.
12569 Clarify explanation of HP compiler bug.
12570 Redo example output tp match current CVS snapshot.
12571 Use @example.org in email addresses when the examples
12572 might get inadvertently cut-and-pasted into user code.
12573 Remove example of autom4te usage that doesn't seem to work now.
12574 Use modern AC_INIT (except when the example is meant to be
12575 shown with Autoconf 2.13).
12576 Update ksh info for Solaris 9 and later.
12578 Modernize description of Automake versions a bit.
12579 Don't claim a future version of Autoconf is near.
12580 * doc/install.texi: Reword to avoid some formatting glitches.
12582 2005-06-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
12584 * doc/autoconf.texi: Add [] to examples, so that the manual
12585 follows its own advice about quoting better.
12586 Reword to avoid some formatting glitches.
12587 * doc/installt.exi: Reword to avoid some formatting glitches.
12589 * doc/autoconf.texi (Limitations of Builtins) <case>: Mention
12590 Tru64 ksh pattern matching bug. Reported against Libtool by
12591 Albert Chin <libtool@mlists.thewrittenword.com> and
12592 Nicolas Joly <njoly@pasteur.fr>.
12594 2005-06-06 Stepan Kasal <kasal@ucw.cz>
12596 m4_cdr of one-member list was [[]] (one-member list containing an
12597 empty string) instead of [] (an empty list. Callers were skewed to
12598 match this misbehaviour. As a consequence of this:
12599 - m4_foreach([x], [], [foo]) expanded to `foo', while
12600 - the expansion of m4_foreach([x], [[]], [foo]) was empty.
12601 This bug has been fixed:
12603 * lib/m4sugar/m4sugar.m4 (m4_cdr): If only one argument is given,
12604 expand to an empty string; print error msg if called without
12606 (m4_foreach, m4_map, m4_map_sep): Don't expect the previous
12607 misbehaviour; handle [] and [[]] correctly.
12609 2005-06-06 Stepan Kasal <kasal@ucw.cz>
12611 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Nuke ac_max_here_lines.
12612 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Simplify the sed
12613 scripts created and the loop applying them, use _AC_SED_CMD_LIMIT.
12615 2005-06-06 Ralf Menzel <menzel@ls6.cs.uni-dortmund.de> (trivial change)
12617 * doc/autoconf.texi (Limitations of Usual Tools): Solaris' awk cannot
12618 swallow records with more than 99 fields.
12619 * lib/autotest/general.m4 (AT_INIT): Use the awk builtin `split' to
12620 parse the long line.
12622 2005-06-04 Stepan Kasal <kasal@ucw.cz>
12624 * doc/autoconf.texi (Limitations of Usual Tools): AIX awk cannot
12625 swallow literals longer than 399. Reported by Ralf Wildenhues.
12626 * lib/autotest/general.m4 (AT_INIT): Pass $at_groups though stdin,
12627 to workaround this limitation.
12629 2005-06-03 Steven G. Johnson <stevenj@alum.mit.edu>
12631 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Find g95 in addition
12632 to gfortran, and make these the first two compiler names
12633 checked (following the general autoconf preference for gcc).
12635 2005-06-03 Stepan Kasal <kasal@ucw.cz>
12637 * tests/Makefile.am (check_SCRIPTS): Set to $(wrappers).
12638 (DISTCLEANFILES): Remove $(check_SCRIPTS).
12639 (testsuite): Make sure autotest.m4f is up-to-date before using it.
12641 2005-06-02 Paul Eggert <eggert@cs.ucla.edu>
12643 * lib/autotest/general.m4 (AT_INIT): Don't create a regular
12644 expression of unbounded size when processing the --list
12645 option. This runs afoul of a limit of 399 bytes per regular
12646 expression on AIX. Problem reported by Ralf Wildenhues.
12648 2005-06-01 Paul Eggert <eggert@cs.ucla.edu>
12650 * NEWS: Note yesterday's changes to AC_SUBST and AC_SUBST_FILE.
12651 * doc/autoconf.texi (Particular Headers): Reword example
12652 for multiline stdbool replacement.
12653 (Setting Output Variables): Reword text a bit. Don't
12654 give all the details about |#_!!_#|.
12655 Reword description of line replacement.
12657 2005-05-31 Dan Manthey <dan_manthey@partech.com>
12659 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Output variables may
12660 now contain newlines, and substituted files must be referenced on
12661 a line alone; the sed scripts to substitute them are now very
12663 (_AC_SED_CMD_LIMIT): Added; single place to store limit on how many
12664 commands can be put in a sed script portably.
12665 * doc/autoconf.texi (Setting Output Variables): Document above
12666 changes. (Particular Header Checks) <AC_HEADER_STDBOOL>: Give exaple
12667 use of multiline substitution.
12668 * tests/torture.at: No longer expect substitution of newline to fail.

12677 * tests/local.at: Don't attempt to check for negated character
12678 classes in shell scripts. The test was too brittle.
12680 2005-05-25 Stepan Kasal <kasal@ucw.cz>
12682 * bin/autoconf.as: Don't use "shift 2"; it's not portable enough.
12683 * doc/autoconf.texi (Limitations of Builtins): Document this
12686 2005-05-24 Stepan Kasal <kasal@ucw.cz>
12688 * lib/m4sugar/m4sh.m4 (_AS_ECHO_LOG): New macro to factor out
12689 common code; used in many places in the tree.
12690 (AS_ESCAPE): Make the pattern a bit simpler; use \& insetad of \1.
12691 (_AS_ECHO_UNQUOTED): Move the macro lower; no code change.
12693 * lib/m4sugar/m4sugar.m4 (m4_ifset): Use m4_ifval.
12695 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Merge the two error
12696 messages when ac_unique_file is not found.
12697 (AC_CONFIG_MACRO_DIR): Simplify the `if' at the end.
12698 (AC_MSG_CHECKING, AC_MSG_RESULT): Put braces around the two echo
12699 commands, for consistency with AC_MSG_ERROR and such.
12701 * bin/autoconf.as: Make more use of "shift 2" in option processing.
12703 * bin/Makefile.am: Merge the two rules for creating scripts.

12711 2005-05-20 Stepan Kasal <kasal@ucw.cz>
12713 * NEWS: @top_builddir@ is now a dirname, ac_top_builddir will follow.
12714 * lib/autoconf/status.m4 (_AC_SRCDIRS): Rename ...
12715 (ac_top_builddir): ... this ...
12716 (ac_top_build_prefix): ... to this; the old name is also kept, for
12717 backward compatibility.
12718 (ac_top_builddir_sub): New variable, without the trailing slash,
12720 (_AC_OUTPUT_FILES): s/@top_builddir@/$ac_top_builddir_sub/
12721 * doc/autoconf.texi (Configuration Actions): Rename
12722 ac_top_builddir to ac_top_build_prefix.
12723 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Rename

12732 2005-05-17 Stepan Kasal <kasal@ucw.cz>
12734 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Don't m4_quote the second
12735 argument to m4_foreach. I guess it was necessary in the past,
12736 but I think it's a no-op now.
12738 2005-05-17 Stepan Kasal <kasal@ucw.cz>
12740 * lib/autoconf/general.m4 (_AC_INIT_HELP): Merge two consecutive
12741 ``cat <<_ACEOF'' commands to one.
12742 (_AC_CANONICAL_SPLIT): Use expr, not ``echo|sed.''
12743 * lib/autoconf/status.m4: On various places, use expr instead of
12745 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST):
12746 (_AC_CONFIG_SPLIT_FILE_IN): New macros, to factor out common code.
12747 * lib/autotest/general.m4 (AT_INIT): Use expr to get the numbers from
12749 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Use awk to search for
12750 the wrong patterns between ``case'' and ``esac.'' The previous
12751 code had false positives.
12753 2005-05-14 Alexandre Duret-Lutz <adl@gnu.org>
12755 * lib/autoconf/functions.m4 (_AC_LIBOBJ_ALLOCA): Prepend ${LIBOBJDIR},

12820 quoting rules. Problems noted by Stepan Kasal.
12821 Also, throughout this document, be more careful about white space.
12822 "blank", "white space", and "space" all have different meanings
12823 and we should be careful to say what we mean.
12825 2005-05-05 Paul Eggert <eggert@cs.ucla.edu>
12827 Fix C++ related problems reported by Werner Lemberg.
12828 * doc/autoconf.texi (C++ Compiler): Mention .cpp extension.

12862 * doc/autoconf.texi (External Software): Replace AC_DEFINE_UNQUOTED
12863 by AC_DEFINE; it was a mistake.

12866 2005-04-25 Stepan Kasal <kasal@ucw.cz>
12868 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): A tiny optimization.
12870 2005-04-22 Stepan Kasal <kasal@ucw.cz>
12872 * doc/autoconf.texi (External Software): Quadrigraphs are not
12873 processed correctly in AS_HELP_STRING; avoid this in the examples.
12874 * lib/m4sugar/m4sh.m4 (AS_HELP_STRING): Add a FIXME about quadrigraphs.
12875 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Likewise; and rephrase the
12876 comment and reduce m4_default([foo], []) to [foo].
12877 (m4_strip): Update the explanation.
12879 2005-04-19 Paul Eggert <eggert@cs.ucla.edu>
12881 * lib/autoconf/general.m4 (_AC_INIT_PREPARE, _AC_RUN_IFELSE):
12882 Remove core.conftest.* too; it's generated by Tru64 5.1.
12883 Problem reported by Jennis Pruett.
12884 * lib/autoconf/functions.m4
12885 (AC_FUNC_SETVBUF_REVERSED, AC_FUNC_UTIME_NULL):
12886 Don't bother to remove core files; AC_RUN_IFELSE should do that

12891 * lib/m4sugar/m4sugar.m4 (m4_bpatsubsts): Add the b- to comment, too.

12933 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS):
12934 Merge `-z option' as well for the benefit of Solaris link flags. Pass
12935 whole-archive (-zallextract, -zdefaultextract) options in the hope of
12936 unique libraries, for the Sun Fortran 95 8.0 compiler. Bug reported
12937 against Libtool by Yury Puhalsky <pooh@cryptopro.ru>.

12941 * NEWS: The configure command now warns you if you attempt to use
12942 a directory whose name contains a special character like space,
12944 * doc/autoconf.texi (Installation Directory Variables): Allow

12959 ac_pwd, and quote srcdir.
12960 * lib/autotest/general.m4 (AT_INIT): Quote file name args.
12962 * doc/autoconf.texi: Fix some systematic formatting problems.
12963 ".)" needs a following @: if not at the end of a sentence, and
12964 similarly for "!)". "etc." should be preceded by a comma.
12965 "n-th" -> "@var{n}th". pdksh is still buggy, so update its date.
12967 2005-03-22 Bruno Haible <bruno@clisp.org>
12969 * doc/autoconf.texi (Input): Mention that AC_CONFIG_AUX_DIR's

12972 2005-03-07 Stepan Kasal <kasal@ucw.cz>
12974 * doc/autoconf.texi (Quotation Rule Of Thumb): Mention that the

12979 2005-02-24 Stepan Kasal <kasal@ucw.cz>
12981 * lib/autoconf/c.m4 (AC_PROG_CC): Be more careful to skip
12982 `/usr/ucb/cc'; use `cl.exe' to distinguish the MS compiler
12983 from a Common Lisp's `cl'.
12984 (AC_PROG_CXX): Behave according to the documentation: don't
12985 search for $ac_tool_prefix$CCC and $CCC, just set CXX=$CCC;
12986 make the variable CCC precious; use `cl.exe', not `cl'.

12989 Alexandre Duret-Lutz <adl@gnu.org>
12991 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin from
12992 /dev/null, as "configure" shouldn't read stdin, and this insulates
12993 us from problems (e.g., when testing for "cl"). Also, do this
12994 redirection before invoking "hostname" or "uname", and keep the
12995 original input stream available via...
12996 (AS_ORIGINAL_STDIN_FD): ... this new macro.
12997 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't

13009 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N_PREPARE): Don't set ECHO_C to
13010 newline if neither \c nor -n work, as that would output two
13011 newlines. Prefer -n to \c. Reported by Stepan Kasal.
13013 2005-02-12 Stepan Kasal <kasal@ucw.cz>
13015 * lib/m4sugar/m4sh.m4 (AS_IF): Define by m4_defun, not m4_define.

13019 2005-02-12 Paul Eggert <eggert@cs.ucla.edu>
13021 Undo previous change, except keep the change to
13022 lib/autoconf/programs.m4 that replaced grep with shell
13023 pattern-matching. This is because net-snmp configure reads stdin.
13024 Reported by Noah Misch.

13028 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin
13029 from /dev/null, as "configure" shouldn't read stdin, and this
13030 insulates us from problems (e.g., when testing for "cl").
13031 Suggested by Alexandre Duret-Lutz. Also, do this redirection
13032 before invoking "hostname" or "uname".
13033 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
13034 _AC_LINK_IFELSE): Undo previous change, as it's no longer needed.
13035 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Don't bother with
13036 "</dev/null" since it's now done at the top of 'configure'.

13038 * lib/autoconf/programs.m4 (_AC_PATH_PROG_FLAVOR_GNU): Likewise.
13039 Also, replace grep with shell pattern-matching, to save a process.

13043 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
13044 _AC_LINK_IFELSE): Redirect stdin to /dev/null, in an attempt to
13045 avoid thinking that Allegro Common Lisp's "cl" command is a C++

13062 Fix some @code's that should have been @env's, and vice versa.
13063 Sort environment variable names.
13064 Mention that shells no longer inherit IFS.
13065 Don't recommend PATH_SEPARATOR=';' so strongly.
13066 Mention that $RANDOM might expand to the empty string.
13067 "symlink" and "soft link" -> "symbolic link".

13207 Simplify the implementation of m4_require (a.k.a. AC_REQUIRE).
13208 Update the long comment explaining it.
13210 m4_require no longer writes an ``is required by'' line to the
13211 execution stack. It contains only one bit of non-redundant
13212 information: that the macro was required, not called. And even
13213 this bit is useless in most situations: have you ever met a macro
13214 which both calls and requires the same macro?
13216 * lib/m4sugar/m4sugar.m4 (_m4_defun_pro): Don't push a diversion...
13217 (_m4_defun_pro_outer): ... only via this macro, for the outermost

13264 * doc/autoconf.texi (Shell Substitutions): Fix typo in case statement.
13265 Warn about newline stripping in `` and $(). Update Solaris
13267 (Limitations of Builtins): Use expr "X...", not expr "x...", as

13318 (_m4_divert_n_stack): New macro; the expansion is
13319 <newline>m4_divert_stack, if m4_divert_stack is defined, and void
13321 (m4_divert, m4_divert_push, m4_divert_pop, m4_init): Use it.
13322 (m4_divert_push, m4_divert_pop, _m4_defun_epi): Don't expand the word
13323 stored in _m4_divert_diversion or _m4_divert_dump.
13324 (m4_divert_pop): When the parameter is given, compare the symbolic
13325 name with the last diversion pushed on the stack. Previously, the
13326 current diversion was compared with the numeric value of the
13327 diversion given as the parameter.
13328 (m4_require): If the macro hasn't been expanded yet, call ...

13636 * lib/autoconf/functions.m4 (AC_FUNC_MEMCMP): Use
13637 "char c = '\200';" rather than "char c = 0x80;" as the

13816 2004-08-19 Paul Eggert <eggert@cs.ucla.edu>
13818 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C),
13819 AC_C_LONG_DOUBLE): Undo 2004-06-04 change, as it didn't work with
13820 HP-UX 11.23 cc/aCC or Tru64 4.0 cc. Problem reported by Noah Misch in
13821 <http://lists.gnu.org/archive/html/autoconf/2004-07/msg00004.html>.
13823 More fixes to support spaces in the name of the build directory.
13824 This isn't a complete fix but it's an improvement.
13826 * bin/autoconf.as (autom4te_options): New var.
13827 Use it instead of appending to AUTOM4TE, so that we can allow
13828 spaces in the build directory's absolute name.
13829 * bin/autoheader.in ($autoconf): Allow spaces in file names.

13880 with pdksh, too. Problem reported by Patrick Welche via

13883 useful for pkdsh, too.
13885 2004-06-24 Paul Eggert <eggert@cs.ucla.edu>
13887 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Require
13888 _AS_UNSET_PREPARE, so that we can use $as_unset directly.
13889 Don't fail if ENV or BASH_ENV is readonly.
13890 (AS_SHELL_SANITIZE): Don't fail if ENV, MAIL, MAILPATH, LC_ALL,
13891 etc. are read only. Problem reported by Ludovic Courtes.
13893 2004-06-23 Noah Misch <noah@cs.caltech.edu>

13901 * doc/autoconf.texi (File System Conventions): Warn about
13902 names like "aux". Problem reported by Eric Blake.
13904 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY (C)): Use division
13905 by zero instead of array size, so that we can use any arithmetic
13906 constant expression (instead of requiring an integer constant
13907 expression). This allows us to test expressions like DBL_MAX <
13908 LDBL_MAX, which didn't conform to the C standard using the old
13910 (AC_C_LONG_DOUBLE): Put back in the tests for LDBL_MAX and LDBL_EPSILON,
13911 now that we can do floating-point tests at compile time.
13913 2004-06-02 Paul Eggert <eggert@cs.ucla.edu>
13915 * lib/autoconf/c.m4 (AC_C_LONG_DOUBLE): Don't check LDBL_MAX
13916 and LDBL_EPSILON, as the resulting expression isn't an
13917 integer constant expression and violates the C standard.
13918 Problem reported by Nelson H. F. Beebe. Also, check
13919 for "L" suffix, and check that long double doesn't have
13920 worse range or precision than double, that mixed-mode
13921 arithmetic doesn't generate a diagnostic, that double
13922 constants fit in long double.
13924 2004-06-03 Kevin Ryde <user42@zip.com.au>

13951 change). Patch reported by Ralf Wildenhues in
13952 <http://mail.gnu.org/archive/html/bug-autoconf/2004-05/msg00092.html>.
13954 * lib/autoconf/functions.m4 (AC_FUNC_MBRTOWC): Don't assume that a
13955 function F exists if the compiler and linker let you compile an
13956 expression like (F != 0). Recent versions of GCC optimize away
13957 the reference to F in that case, since every function address must
13958 be nonzero, so the link succeeds even if F does not exist.
13959 Problem reported by Manu in
13960 <http://mail.gnu.org/archive/html/bug-gnu-utils/2004-05/msg00060.html>.

13974 * doc/autoconf.texi (Function Portability): Add strerror_r, cross
13975 referencing AC_FUNC_STRERROR_R.
13977 * doc/autoconf.texi (Particular Functions): In AC_FUNC_CLOSEDIR_VOID,
13978 note pessimistic assumption when cross compiling.
13980 2004-05-16 Paul Eggert <eggert@cs.ucla.edu>
13982 * doc/autoconf.texi (Limitations of Make): Note that BSD make
13983 (until 2004) invoked subcommands with sh -e, contra POSIX.
13984 Reported by Kevin Ryde.
13986 2004-05-10 Eric Sunshine <sunshine@sunshineco.com>
13988 * programs.m4 (_AC_PROG_GREP): Fixed bug where PATH argument handed to
13989 _AC_PATH_PROG_FEATURE_CHECK contained leading whitespace (i.e.
13990 " $PATH:/usr/xpg4/bin"). This resulted in bogus tests, such as
13991 `test -f " /usr/bin/grep"', which _always_ failed.
13992 (AC_PROG_SED): Ditto bogus PATH fix.
13993 * autoconf.texi (AC_PROG_GREP): Properly document that this macro
13994 requires that grep correctly supports _multiple_ `-e' options, rather
13995 than stating only that grep should accept `-e'.
13997 2004-05-03 Paul Eggert <eggert@cs.ucla.edu>
13999 Port to C99, which requires that 'exit' be declared.
14001 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Use AC_INCLUDES_DEFAULT
14002 to ensure that stdlib.h is included.
14003 * lib/autoconf/functions.m4 (_AC_LIBOBJ_ALLOCA, AC_FUNC_SETPGRP,
14004 AC_FUNC_STRTOD, AC_FUNC_SETVBUF_REVERSED, AC_FUNC_FORK, _AC_FUNC_FORK,
14005 _AC_FUNC_VFORK, AC_FUNC_WAIT3): Likewise.
14006 * lib/autoconf/specific.m4 (AC_SYS_RESTARTABLE_SYSCALLS): Likewise.
14007 * lib/autoconf/types.m4 (AC_TYPE_GETGROUPS): Likewise.
14008 * lib/autoconf/headers.m4 (AC_HEADER_STDC): Include <stdlib.h>
14009 when using 'exit' in a test; C99 requires that 'exit' be declared.
14011 2004-05-02 Paul Eggert <eggert@cs.ucla.edu>
14013 * doc/autoconf.texi (Particular Programs): AC_PROG_GREP
14014 now prefers 'grep' implementations that accept -e.
14015 (Limitations of Usual Tools): Describe problems of traditional
14016 egrep and fgrep with long input lines, and of traditional grep
14018 * lib/autoconf/programs.m4 (AC_PROG_GREP): Check for -e, too.
14019 (_AC_PROG_GREP): Assume 3rd arg is properly quoted for the shell.
14020 All callers changed. Append /usr/xpg4/bin to the PATH, for
14022 (_AC_FEATURE_CHECK_LENGTH): Discard stderr, so we don't bother
14023 the user with complaints about multiple -e options.
14024 * tests/local.at (AC_STATE_SAVE): Use $GREP, not grep.
14025 Define it with AC_PROG_GREP.
14026 * configure.ac (AC_PROG_GREP): Add.
14027 * lib/freeze.mk (GREP): New macro.
14029 2004-05-02 Eric Sunshine <sunshine@sunshineco.com>
14031 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Consult $SHELL as
14032 a possible candidate only after all others fail, rather than
14033 consulting it first. This improves backward compatibility by
14034 better reflecting the way shell selection occurred in previous
14035 versions of Autoconf, and should help to avoid triggering latent
14036 problems in other packages, such as the one in Automake where zsh
14037 is not handled robustly:
14038 http://mail.gnu.org/archive/html/automake/2004-04/msg00095.html
14039 Although it is not Autoconf's responsibility to work around
14040 problems in Automake, it nevertheless makes sense to avoid
14041 introducing unnecessary incompatibilites.
14043 2004-04-22 Albert Chin-A-Young <china@thewrittenword.com>,
14044 Gary V. Vaughan <gary@gnu.org>
14046 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Don't guess
14047 how deeply nested we are when a suitable tool is found, set the
14048 ac_path_TOOL_found flag.
14049 (_AC_PATH_PROG_FEATURE_CHECK): Encapsulate knowledge of how deeply
14050 nested we are in this macro. Break out of all 3 nested loops if
14051 ac_path_TOOL_found is set.
14053 2004-04-21 Gary V. Vaughan <gary@gnu.org>
14055 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Break out
14056 of the _AS_PATH_WALK loop too if GNU flavor is found.
14058 2004-04-21 Alexandre Duret-Lutz <adl@gnu.org>
14060 * doc/autoconf.texi (Limitations of Make): Update documentation
14061 for `$<'. New entry `Long lines', based on a report from Simon
14062 Josefsson. Augment the documentation for SHELL = @SHELL@ with a
14063 paragraph about DJGPP, based on a mail from Richard Dawe.
14065 2004-04-20 Paul Eggert <eggert@twinsun.com>
14067 * tests/c.at (C keywords): Don't assume that GCC supports
14068 "restrict" and "inline", as sufficiently-old GCC versions do not
14069 (also, GCC configured to be in pedantic C89 mode does not).
14070 Problem reported by Sumit Pandya in:
14071 http://mail.gnu.org/archive/html/autoconf/2004-04/msg00092.html
14073 * lib/autoconf/c.m4 (_AC_PROG_CC_G, _AC_PROG_CXX_G): Don't
14074 consider -g to work if it generates warnings when plain compiles
14075 don't. Problem reported by Braden McDaniel in:
14076 http://mail.gnu.org/archive/html/autoconf-patches/2003-07/msg00014.html

14079 reported by Jim Meyering in:
14080 http://mail.gnu.org/archive/html/bug-coreutils/2004-02/msg00060.html
14082 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Remove potential
14083 linker output files before linking, to work around IRIX 6 linker bug.
14084 Problem reported by Rainer Orth in:

14087 2004-04-20 Gary V. Vaughan <gary@gnu.org>
14089 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Make the
14090 best tool so far counter rely on the tool path variable name to
14091 avoid checks for one tool being affected by the results of running
14092 the length check on a previous tool.
14094 * lib/autoconf/programs.m4 (_AC_PROG_GREP): Take an additional
14095 match expression argument, as different greps have different
14096 regular expression flavours.
14097 (AC_PROG_FGREP): Pass 'FGREP'. fgrep treats all match chars as
14099 (AC_PROG_EGREP): Pass 'EGREP$'.
14100 (AC_PROG_GREP): Pass 'GREP$'.
14102 2004-04-20 Albert Chin-A-Young <china@thewrittenword.com>
14104 * lib/autoconf/programs.m4 (AC_PROG_GREP): Cache variable
14105 is `ac_cv_path_GREP', not `oc_cv_path_GREP'.
14107 2004-03-29 Paul Eggert <eggert@twinsun.com>
14109 * doc/autoconf.texi (Particular Headers, Particular Types, Generic
14110 Types, Specific Compiler Characteristics, System Services,
14111 Obsolete Macros): Use 'long int', 'short int', 'unsigned int'
14112 etc. consistently instead of 'long', 'short', 'unsigned' etc.
14113 * lib/autoconf/c.m4 (AC_LANG_INT_SAVE(C), AC_C_BIGENDIAN): Likewise.

14127 * doc/autoconf.texi (Particular Structures): AC_STRUCT_TIMEZONE
14128 now defines HAVE_DECL_TZNAME if it is declared, when
14129 HAVE_STRUCT_TM_TM_ZONE is not defined.
14130 * lib/autoconf/types.m4 (AC_STRUCT_TIMEZONE): Implement this.
14131 Do not assume atoi. Rely on HAVE_DECL_TZNAME when testing
14134 2004-03-28 Steven G. Johnson <stevenj@fftw.org>
14136 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Corrected
14137 superfluous backslashing of quotes (") in sed expressions;
14138 thanks to Paul Eggert.
14140 2004-03-26 Steven G. Johnson <stevenj@alum.mit.edu>
14142 * lib/autoconf/fortran.m4 (_AC_PROG_FC): new name of Intel
14143 Fortran compiler is ifort, also added pghpf; thanks to Nelson
14144 H. F. Beebe for the bug report.
14146 2004-03-26 Steven G. Johnson <stevenj@fftw.org>

14189 * doc/autoconf.texi (Generic Compiler Characteristics): Document it.
14190 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Use long int rather than
14191 int; avoid "a `$1'" since this isn't grammatical if $1 begins with a
14193 (AC_CHECK_ALIGNOF): New macro.
14194 * tests/mktests.sh (ac_exclude_list): Exclude AC_CHECK_ALIGNOF.

14198 2004-03-03 Paul Eggert <eggert@twinsun.com>
14200 * bin/Makefile.am (edit): Don't use $< in a context where
14201 POSIX doesn't require support for it. Use $@.in instead.
14202 Problem reported by Anthony N. Frasso in
14203 <http://mail.gnu.org/archive/html/autoconf/2004-03/msg00008.html>.

14232 AC_SUBST provides no portable way to escape literal newlines.
14234 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS): Ignore all
14235 flags of the form -lcrt*.o, not just -lcrt[01].o and -lcrtbegin.o.
14236 Darwin uses -lcrt2.o and there's little point to cataloging all

14262 Eric Sunshine <sunshine@sunshineco.com>
14263 Paul Eggert <eggert@twinsun.com>
14265 * lib/m4sugar/m4sh.m4 (M4SH-SANITIZE): New diversion.
14266 (AS_INIT): Output shell initialization there. Removed optional
14267 parameter. Expand _AS_SHELL_FN_SPY.
14268 (AS_INIT_WITH_SHELL_FN): Removed.
14269 (_AS_SHELL_FN_SPY): New macro.

14276 (_AS_RUN): Move it here, support testing with eval.
14277 (AS_REQUIRE_SHELL_FN): Require shell functions when
14279 (_AS_LINENO_WORKS): Put around braces, we do not

14282 use AS_INIT_WITH_SHELL_FN.

14292 macros with AU_DEFINE.
14293 * lib/autoconf/headers.m4 (AC_USG, AC_MEMORY_H,
14294 AC_DIR_HEADER): Use AU_DEFUN's third parameter.

14297 * lib/autoconf/specific.m4 (AC_HAVE_POUNDBANG,

14313 * lib/autoconf/general.m4 (_AC_INIT_COPYRIGHT): Add 1992 thorugh

14315 the 2003-05-22 change, which removed the older years from the list.
14316 * lib/autoconf/status.m4 (AC_OUTPUT): Update copyright date to 2004.
14318 2004-01-27 Gary V. Vaughan <gary@gnu.org>

14327 egrep and fgrep respectively if $GREP -E/-F don't work.
14328 (_AC_PATH_PROG_FEATURE_CHECK): Factor out the common core of
14329 _AC_PROG_GREP, and AC_PROG_SED.
14330 (_AC_FEATURE_CHECK_LENGTH): New helper macro for finding the
14331 longest input length accepted by a command.

14333 * doc/autoconf.texi (Particular Programs): Document the changes.
14336 2004-01-27 Paul Eggert <eggert@twinsun.com>
14338 * bin/autoconf.as ($version): Update copyright from 2003 to 2004.
14339 * bin/autoheader.in, bin/autom4te.in, bin/autoreconf.in,
14340 bin/autoscan.in, bin/autoupdate.in, bin/ifnames.in: Likewise.
14341 * lib/autoconf/general.m4 (_AC_INIT_COPYRIGHT): Likewise.
14343 * Makefile.in, aclocal.m4, configure, bin/Makefile.in,
14344 bin/autoconf.in, config/Makefile.in, config/config.guess,
14345 config/config.sub, config/install-sh, config/mdate-sh,

14362 * doc/autoconf.texi (Default Includes): Include <stdint.h> even if
14363 HAVE_INTTYPES_H is defined. This is needed on Tru64 5.1b with
14364 Compac C V6.5-207 (dtk), which defines uintmax_t in <stdint.h> but
14365 not <inttypes.h>. Problem reported by Tim Mooney in
14366 <http://mail.gnu.org/archive/html/bug-coreutils/2004-01/msg00147.html>.
14367 * lib/autoconf/headers.m4 (_AC_INCLUDES_DEFAULT_REQUIREMENTS):
14370 * lib/autoconf/programs.m4 (AC_PROG_SED): Use diff, not sed;
14371 otherwise "make check" fails because it forbids cmp (I guess
14372 because cmp treats files as binary on DOS-like systems).
14374 * tests/mktests.sh: Update copyright date to 2004, since some tests
14375 have changed in 2004.
14377 2004-01-23 Gary V. Vaughan <gary@gnu.org>
14379 * lib/autoconf/programs.m4 (AC_PROG_SED): New macro to test for a
14380 non-truncating sed or gsed program in PATH.
14381 * tests/acprograms.at: Add it.
14382 * doc/autoconf.texi (Particular Programs): Document it.
14385 2004-01-15 Paul Eggert <eggert@twinsun.com>
14387 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Try -std, not -std1, since
14388 -std1 disables some useful extensions on Tru64. Problem reported
14389 by N. Lichtmaier in
14390 <http://mail.gnu.org/archive/html/autoconf/2004-01/msg00100.html>.
14392 2004-01-14 Paul Eggert <eggert@twinsun.com>
14394 * doc/autoconf.texi (Programming in M4sh): Document that
14395 AS_MKDIR_P succeeds if the destination is a symbolic link
14396 to an existing directory.
14397 (Limitations of Usual Tools): Note that mkdir -p might not
14398 succeed on symlinks to directories.
14400 2004-01-13 Paul Hilfinger <hilfinger@CS.Berkeley.EDU>
14402 * lib/autoconf/autoupdate.m4 (AU_DEFUN): Grammar fix in comment.
14403 * bin/autoheader.in: Grammar fix in message.
14404 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P):
14405 Test for dir before calling mkdir -p. (trivial changes)
14407 2004-01-13 Eric Blake <ebb9@byu.net>
14409 * doc/autoconf.texi (Obsolete Macros): In AC_TRY_COMPILE and
14410 AC_TRY_LINK, s/AC_LANG_SOURCE/AC_LANG_PROGRAM/. (trivial change)
14412 2004-01-10 Jim Meyering <jim@meyering.net>
14414 * doc/autoconf.texi (Running the Preprocessor): Correct grammar.
14416 2004-01-09 Paul Eggert <eggert@twinsun.com>
14418 * lib/autoconf/general.m4: Fix bug: AC_CHECK_SIZEOF evokes a warning
14419 with `autoconf -Wall,error'. Bug reported by Eric Blake in:
14420 http://mail.gnu.org/archive/html/autoconf-patches/2004-01/msg00000.html
14421 (_AC_COMPUTE_INT_COMPILE): Invoke _AC_COMPILE_IFELSE, not
14422 AC_COMPILE_IFELSE, since we now assume our caller invokes
14423 AC_LANG_COMPILER_REQUIRE, for symmetry with _AC_COMPUTE_INT_RUN.
14424 (_AC_COMPUTE_INT_RUN): Likewise, for _AC_RUN_IFELSE instead
14425 of AC_RUN_IFELSE; this avoids the warning mentioned above.
14426 (_AC_COMPUTE_INT): Invoke AC_LANG_COMPILER_REQUIRE.
14428 2004-01-07 Paul Eggert <eggert@twinsun.com>
14430 * lib/autoconf/general.m4 (_AC_LIBOBJS_NORMALIZE): Avoid \$ inside
14431 `"'...'"`, as it's confusing (and I suspect it may not work on
14432 some platforms). The code was incorrect anyway, as it assumed
14433 that \$ evaluated to itself in that context. Reported by
14434 Alexandre Duret-Lutz.
14436 2004-01-07 Alexandre Duret-Lutz <adl@gnu.org>
14438 * lib/autom4te.in (Automake-preselections): Preselect AC_LIBTOOL_TAGS
14439 and _LT_AC_TAGCONFIG.

14444 example, and add more examples. Reported by Eric Sunshine.

14448 * doc/autoconf.texi (Limitations of Usual Tools):
14449 Remove warning against "rm -fr" introduced yesterday; it
14452 * bin/Makefile.am (autoconf, autoheader, autom4te, autoreconf,
14453 autoscan, autoupdate, ifnames): Don't use chmod -w.
14454 * lib/Makefile.am (autom4te.cfg): Likewise.
14455 * doc/autoconf.texi (Limitations of Usual Tools): Warn against

14461 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Speed up sed scripts
14462 by doing lineno substitution only on lines containing "$LINENO".

14466 * lib/autoconf/general.m4 (AC_ARG_PROGRAM):
14467 Use "rm -f" to remove conftest.sed, not plain "rm".
14468 Bug reported by David Relson in
14469 <http://mail.gnu.org/archive/html/autoconf/2004-01/msg00011.html>.
14471 * Makefile.am (autom4te-update):
14472 Replace "rm -rf" and "rm -fr" with "rm -f -r", as POSIX requires.
14473 * Makefile.maint (my-distcheck, do-po-update): Likewise.
14474 * doc/autoconf.texi (Guidelines): Likewise.

14481 * tests/tortue.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS,
14483 * doc/autoconf.texi (Limitations of Usual Tools):

14488 * doc/autoconf.texi (Limitations of Usual Tools): Mention that cc
14489 -c -o might not work. From a suggestion by Kevin Ryde.
14490 (C Compiler, Generating Sources, Limitations
14491 of Usual Tools, Limitations of Make, Making testsuite Scripts):
14492 Don't put '-o' after non-options, as POSIX doesn't allow this.
14493 Mention that cc's name might be gcc or c89 or whatever.
14495 2004-01-04 Kevin Ryde <user42@zip.com.au>
14497 * doc/autoconf.texi: Add various further index entries.
14499 2003-12-29 Paul Eggert <eggert@twinsun.com>
14501 * bin/autoreconf.in (autoreconf_current_directory):
14502 Fix typo: mkdir without umask arg.
14504 2003-12-27 Alexandre Duret-Lutz <adl@gnu.org>
14506 * doc/autoconf.texi (Limitations of Make) <Automatic rule rewriting>:
14507 Documents OSF1/Tru64 make behavior. Replace `VPATH = ../src' by
14508 `VPATH = ../pkg/src' in examples to make the OSF1/Tru64 make
14509 explanation clearer.
14511 2003-12-24 Andreas Schwab <schwab@suse.de>
14513 * doc/autoconf.texi (Default Includes): Fix misspelling of

14520 * tests/atlocal.in: Store the result here.
14521 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Extracted from

14523 of explicitly testing.
14524 (AT_CHECK_PERL_SYNTAX): Moved from tools.at.
14525 (AT_CHECK_AUTOCONF): Test for the configure script syntax.
14526 * tests/tools.at (Syntax of the shell scripts): Simplify

14545 _AS_LINENO_WORKS, use it to find out if shell
14547 (_AS_LINENO_WORKS): Don't find another shell if $LINENO

14596 parameter of AU_DEFUN.

14600 * lib/autoconf/status.m4 (AC_LINK_FILES): Move the message into
14601 the expanded body, consistently with other macros such as AC_USG.
14603 2003-11-17 Paul Eggert <eggert@twinsun.com>
14605 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Put at least 14 bytes
14606 into the initial confdefs.h, to work around a bug in NextStep 3.3
14607 patch 3 reported by Eric Sunshine.
14609 2003-11-15 Kevin Ryde <user42@zip.com.au>
14611 * doc/autoconf.texi (Using System Type): Revise, showing $host rather
14612 than $target since the latter is not usual, add guidelines on when to
14613 use or not use the system type.

14617 * doc/autoconf.texi (Limitations of Usual Tools): Fix what looks like a
14618 typo misrepaired by an auto-spellcheck.

14790 Problems reported by Eric Sunshine.
14792 2003-10-08 Steven G. Johnson <stevenj@alum.mit.edu>
14794 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Omit quoted
14795 -mGLOB_options_string stuff for Intel ifc, which can cause

14801 * doc/autoconf.texi: Document new FC Fortran macros.
14803 2003-10-08 Gary V. Vaughan <gary@gnu.org>
14805 * lib/autoconf/general.m4 (AC_CONFIG_MACRO_DIR): Stub out a macro

14819 * lib/autoconf/fortran.m4 (_AC_PROG_FC_G): Use language-specific
14820 cache variable instead of $G77 to decide whether to include -O2,
14821 since $G77 is specific to Fortran 77.
14823 2003-10-03 Steven G. Johnson <stevenj@alum.mit.edu>
14825 * lib/autoconf/fortran.m4 (AC_FC_FREEFORM): Support Absoft "-f
14826 free" flag. Re-order flags tested into rough order of popularity.
14828 2003-10-03 Steven G. Johnson <stevenj@alum.mit.edu>
14830 * lib/autoconf/fortran.m4 (AC_PROG_FC): Reverse the order of the
14831 arguments so that it can be used with syntax identical to
14832 AC_PROG_F77, and so that we can more easily decide to
14833 remove/deprecate the DIALECT optional argument in the future if it
14834 proves troublesome.
14835 (AC_FC_FREEFORM): Exit 77 upon failure to fix test suite for
14836 non-freeform-supporting compilers. Document freeform flags.
14838 2003-10-03 Akim Demaille <akim@epita.fr>

14900 <http://mail.gnu.org/archive/html/autoconf/2003-07/msg00042.html>.
14901 (_AS_MKDIR_P_PREPARE): Change "rm -fr ./-p" to the more-conservative
14902 "test -d ./-p && rmdir ./-p". Suggested by Andreas Schwab in:
14903 http://mail.gnu.org/archive/html/autoconf-patches/2003-09/msg00039.html
14905 2003-09-26 Akim Demaille <akim@epita.fr>
14907 * lib/autoconf/status.m4 (_AC_OUTPUT_COMMANDS): Make sure the
14908 directory for AC_CONFIG_COMMANDS' first argument exists.
14909 This makes valid the invocation of _AC_SRCPATH that follows.
14910 Reported by Eric Sunshine.
14911 * doc/autoconf.texi (Configuration Commands): Adjust.
14913 2003-09-26 Akim Demaille <akim@epita.fr>

14934 The test suite are sometimes assigning timings incorrectly.
14935 Reported by Henk Krus.
14936 Diagnosed by Nicolas Joly.
14938 * lib/autotest/general.m4 (AT_CLEANUP): Rename AT_help as
14940 Instead of making AT_help a sequence of assignments to grow
14941 $at_help_all, just make AT_help_all be the growing contents of
14942 $at_help_all, and make a single assignment in...
14944 (at_times_skip): Flip the meaning and rename as...
14945 (at_times_p): this.
14946 (AT_INIT): When summarizing the test that ran, remove

14956 (ifnames): chmod -w.
14957 * tests/wrapper.as (AUTOCONF, AUTOM4TE, ): Point to tests/
14958 executables, not bin/ executables! Otherwise all the magic needed
14959 to find non installed files is turned off. This caused a failure
14960 of test 40 and 41 that ran aclocal 1.8 which in turn ran autom4te
14961 as found in its environment (sent by tests/autoreconf): pointing
14962 to bin/autom4te that could not find its files.
14963 * tests/mktests.sh: Force the replacement of generated files, for
14964 the sake of "mv" program that are interactive when overwriting a
14966 * config/install-sh: Upgrade from CVS Automake.

14973 2003-09-23 Daniel Jacobowitz <drow@mvista.com> and
14974 Paul Eggert <eggert@twinsun.com>
14976 Trivial change to support GCC's configuration procedure.

15012 willing to edit the output files.
15014 2003-09-10 Akim Demaille <akim@epita.fr>
15016 * tests/fortran.at (GNU Fortran 77): Also exercise AC_FC_SRCEXT
15017 and AC_FC_FREEFORM.
15018 * tests/mktests.sh: Skip AC_FC_SRCEXT.
15019 * lib/autoconf/fortran.m4 (AC_FC_SRCEXT, AC_FC_FREEFORM): Likewise.

15059 2003-09-02 Steven G. Johnson <stevenj@alum.mit.edu>
15061 Add support for newer Fortran dialects. The F77 interface is
15062 unchanged, and continues to support Fortran 77. New FC macros
15063 correspond to all the old F77 macros, with output variables FC,
15064 FCFLAGS, and FCLIBS. AC_PROG_FC defaults to picking the newest
15065 available dialect, but older dialects can be specified. There are
15066 new macros AC_FC_SRCEXT to set the source extension, and
15067 AC_FC_FREEFORM to accept free-form source files.
15069 * lib/autoconf/c.m4 (_AC_LANG_PREFIX(C), _AC_LANG_PREFIX(C++)):

15106 are defaulted by AT_CHECK anyway.
15107 Use AT_CHECK_AUTOM4TE.

15172 * lib/Autom4te/Request.pm, lib/Autom4te/C4che.pm: New.
15173 * bin/autom4te.in: Adjust.
15175 2003-08-21 Akim Demaille <akim@epita.fr>
15177 * lib/Autom4te/General.pm (&file_name_is_absolute): Remove.
15178 (&verbose): Remove.
15179 (&getopt): Adjust the note and verb channels, depending upon
15181 * bin/autoheader.in, bin/autom4te.in, bin/autoscan.in,
15182 * bin/autoupdate.in: Adjust.
15183 Use &verb, not &verbose.
15185 2003-08-21 Akim Demaille <akim@epita.fr>
15187 * bin/autoheader.in (&parse_args): Use &parse_warnings and
15189 ($help): Use Autom4te::ChannelDefs::usage.
15190 * bin/autoscan.in: Use Autom4te::ChannelDefs.
15191 * lib/Autom4te/General.pm: Don't export error: you don't own it.
15193 2003-08-21 Akim Demaille <akim@epita.fr>
15195 First stab at preserving warnings between calls to autom4te,
15196 including when the cache is used.
15198 There are still several issues: (i) there are too many runs of m4
15199 (one for include, one for warnings, and some more), (ii) warnings
15200 spreading on several lines are not handled gracefully, (iii) the
15201 code meant to have the call stack display for errors does not work
15202 (its handling should move from m4 to autom4te).
15204 * bin/autom4te.in Autom4te::Channels, Autom4te::ChannelDefs):
15206 (@preselect): Add m4_warn.
15207 ($exit_status): Remove, use $exit_code.
15208 ($help): Use Autom4te::ChannelDefs::usage.
15209 (&handle_m4): No longer define the m4_warnings.
15210 At each run, extract and report the warnings.
15211 Always cache the result, including if the exit status is on
15212 failure, since if nothing changes, we should result in the same
15213 failure, hence we can use the cache.
15214 * lib/m4sugar/m4sugar.m4 (m4_warning_ifelse, _m4_warning_ifelse)
15215 (_m4_warning_error_ifelse, __m4_warning_error_ifelse, _m4_warn):
15217 (m4_warn): Redefine as a do-nothing: it is its invocation that
15218 matters, as warnings are now reported via traces.
15219 * lib/autoconf/general.m4 (AC_DIAGNOSE): Don't make it a copy of
15220 the contents of m4_warn: make it _call_ m4_warn, so that tracing
15221 the latter reveals calls to the former.
15225 * tests/m4sugar.at (m4@&t@_warn): Use existing warning categories.
15227 2003-08-21 Akim Demaille <akim@epita.fr>
15229 * bin/autoreconf.pm (Autom4te::Channels, Autom4te::ChannelDefs):

15237 (&parse_warnings): Accept a list of warning requests.
15238 (&usage): Return a string, not a side effect.
15239 (cross): New warning category.
15241 2003-08-21 Akim Demaille <akim@epita.fr>
15243 * lib/Autom4te/Configure_ac.pm (&find_configure_ac)
15244 (&require_configure_ac): Accept an optional directory argument.
15245 ($configure_ac): Remove.
15246 * lib/Autom4te/General.pm (&find_configure_ac, &canonfile)
15247 (&catfile): Remove.
15248 * bin/autoheader.in, bin/autoreconf.in, bin/autoupdate.in,
15249 * bin/autoscan.in: Adjust.
15251 2003-08-20 Akim Demaille <akim@epita.fr>
15253 * bin/autoheader.in: Remove duplicate 'use Autom4te::FileUtils'.
15254 Reported by Alexandre Duret-Lutz.
15256 2003-08-20 Akim Demaille <akim@epita.fr>
15258 * bin/autoupdate.in, bin/autoheader.in, bin/autoreconf.in,
15259 * bin/autom4te: Adjust.
15260 In particular, be Autoconf tools are really silent when properly
15261 working, bind the verbosity of the 'note' channel to $verbose.
15262 * lib/Autom4te/General.pm (&find_file, &mtime, &update_file)
15263 (&xsystem, &contents): Remove, since they are exported by...
15264 * lib/Autom4te/FileUtils.pm: this.
15266 * lib/Autom4te/General.pm (&up_to_date_p): Move to...
15267 * lib/Autom4te/FileUtils.pm: here.
15269 2003-08-20 Akim Demaille <akim@epita.fr>
15271 * lib/Autom4te/Channels.pm, lib/Autom4te/ChannelDefs.pm
15272 * lib/Autom4te/Configure_ac.pm, lib/Autom4te/FileUtils.pm: New,

15325 DESCRIPTION rather than FILE and LINE. Shorten result to fit in new,
15326 shorter column three. Add DESCRIPTION to log file content.
15328 2003-08-13 Derek Price <derek@ximbiot.com>
15330 * lib/autotest/general.m4 (AT_INIT): Correct typo in final status
15333 2003-08-12 Derek Price <derek@ximbiot.com>
15335 * lib/autotest/general.m4 (AT_CHECK): Use new _AT_CHECK API.

15353 -lcrt1.o, for OS X. (trivial change)
15355 2003-07-07 Paul Eggert <eggert@twinsun.com>
15357 * lib/autoconf/c.m4 (AC_C_INLINE): Wrap the '#define inline ...'
15358 inside '#ifndef __cplusplus'. Problem reported by
15361 2003-07-06 Bill Clarke <llib@computer.org>
15363 * lib/autoconf/functions.m4 (AC_FUNC_MMAP): Cast pointer to
15364 'long', not 'int', for benefit of Sun's recent C++ compilers
15365 (trivial change). See:

15381 * doc/autoconf.texi (Header Portability): sys/mount.h.
15382 From Gareth McCaughan.
15384 2003-06-23 Akim Demaille <akim@epita.fr>
15386 * lib/autotest/general.m4 (AT_INIT): Report a single config.log,
15387 not all of them. This fixes 1. the fact that when testing
15388 Autoconf there are many many config.log, 2. the incorrect use of
15389 top_srcdir to find config.log.
15390 Don't mix the detailed output of failed test with the summary of
15391 failures. Rather, append detailed log afterwards.
15393 2003-06-23 Akim Demaille <akim@epita.fr>
15395 * tests/local.at (AT_CHECK_CONFIGURE): Adjust to the verbose being
15396 always run: output config.log on $at_group_log.
15398 2003-06-23 Akim Demaille <akim@epita.fr>
15400 * tests/torture.at (#define header templates): Don't use quotes in

15417 error from OSF 4.0 Compaq cc in its default almost-ANSI mode, thereby
15418 ensuring we add -std1 for full-ANSI.
15420 * doc/autoconf.texi (hdrindex): New macro.
15421 Add index entries for portability of various standard header files.

15453 (AT_CLEANUP): ...to here. Undivert TEST_SCRIPT.
15454 (AT_INIT): Support for expected failures.
15456 2003-06-02 Akim Demaille <akim@epita.fr>
15458 * bin/autom4te.in, bin/autoscan.in, bin/autoheader.in: White space

15469 is the inverse of localtime.
15471 2003-05-25 Alexandre Duret-Lutz <adl@gnu.org>
15473 * lib/Autom4te/General.pm (END): Print diagnostics to STDERR.
15474 (handle_exec_errors): New function. Work around $! being
15475 altered by WEXITSTATUS.
15476 (xqx, xsystem): Use handle_exec_errors.
15478 2003-05-23 Alexandre Duret-Lutz <adl@gnu.org>
15480 * lib/Autom4te/General.pm (END): Rewrite exit code processing.
15481 Do not call `_exit()', simply modify `$?'.
15482 (xsystem): Reset $! before running system, and check it afterward.
15483 * tests/tools.at (autoupdating AC_PREREQ): Expect exit status
15484 63 for version mismatches.
15486 2003-05-23 Akim Demaille <akim@epita.fr>
15488 * lib/autoconf/status.m4: Prefer "TAB-SP" to "SP-TAB", because of
15489 Emacs' dangerous whitespace.el behavior (smashing "useless" spaces in
15490 the middle of a line).
15491 * lib/m4sugar/m4sugar.m4: Likewise.
15492 Remove useless spaces in comments.
15494 2003-05-23 Akim Demaille <akim@epita.fr>
15496 * lib/m4sugar/m4sugar.m4 (m4_version_prereq): Failure causes an
15497 exit 63, so that we (or Automake's "missing") can tell the
15498 difference with a plain failure.
15499 * doc/autoconf.texi (Notices): Adjust.

15508 Paul Eggert <eggert@twinsun.com>
15510 * lib/autoconf/c.m4 (_AC_PROG_CXX_EXIT_DECLARATION):
15511 Remove `#include <stdlib.h>' from the list; we should never
15512 make confdefs.h include <stdlib.h> or <cstdlib>, because the
15513 resulting namespace pollution would cause other tests to fail.
15514 Configure scripts run with some older versions of g++ and HP's
15515 aCC would fail due to such an #include. Problems reported by
15516 Matthew Mueller in <http://bugs.debian.org/120704> and by
15518 <http://mail.gnu.org/archive/html/autoconf/2003-05/msg00063.html>.
15519 In the test, use the test declaration before including <stdlib.h>,
15520 as that's closer to how it'll be used.
15522 2003-05-23 Akim Demaille <akim@epita.fr>
15524 * doc/autoconf.texi (Header Portability): ucred.h.
15527 2003-05-22 Paolo Bonzini <bonzini@gnu.org>
15529 Overhaul Autotest's logging: generate separate log files
15530 in testsuite.dir/NNN/testsuite.log, and append them to
15531 testsuite.log instead of re-running the test verbosely.
15533 * lib/autotest/general.m4 (AT_INIT): Use a single redirected
15534 file descriptor, write 0 to at_status_file instead of setting
15535 at_status=0, initialize some new variables (at_status_file,
15536 at_group_log, at_suite_log, at_tee_pipe). Remove the cruft
15537 to rerun the tests, instead append the at_group_log to the
15538 at_suite_log when a test fails.
15539 (AT_SETUP): pipe the test case's output into at_tee_pipe,
15540 with the AS_MESSAGE_LOG_FD redirected to stdout.
15541 (AT_CLEANUP): save the output status in $at_status_file
15542 and restore it, redirect the AS_MESSAGE_LOG_FD back to
15543 its original place.
15544 (AT_CHECK): since tests are run with a redirected stdout,
15545 and used to be re-run in verbose mode, turn some $at_verbose
15546 into echo, and don't redirect the output of testing stdout
15549 * lib/autotest/autoconf.texi (testsuite Scripts): Update
15550 the name of the debugging directory and information about

15670 2003-05-06 Akim Demaille <akim@epita.fr>
15672 Don't try to be smart with aclocal 1.8+ because (i) aclocal no
15673 longer updates aclocal.m4 if useless, (ii) if a file m4_included
15674 by aclocal.m4 is changed it might require the importing of another
15675 m4 extension file, i.e., aclocal must be run.
15677 * bin/autoreconf.in (&run_aclocal, $aclocal_supports_force): New.
15678 (&parse_args): Use --force with aclocal if required and supported.

15690 (&freeze): Lock the $icache_file.
15692 2003-04-29 Derek Price <derek@ximbiot.com>
15694 * lib/autotest/general.m4 (AT_KEYWORDS): Don't use a comma as the
15695 seperator with m4_append_uniq(). It doesn't work.
15696 (AT_CLEANUP): Add `;' to end of at_help_all.
15697 (AT_INIT): Allow --keywords to be specified more than once. When
15698 grepping $at_help_all for keywords, use the field and keyword

15704 * doc/autoconf.texi: Make the dir entries in the autoconf manual
15705 align better with others. I also made some of the individual
15706 entries on one line, for brevity and to make it easier for me to
15707 sort my dir-example file in the Texinfo distribution :).

15774 header causes problems.
15776 2003-03-28 Akim Demaille <akim@epita.fr>
15778 * tests/torture.at (Configuring subdirectories): Require aclocal
15779 1.4, otherwise the test fails, as it does support configure.ac.
15780 This fixes the "test 40 failed" bug reports.

15802 * lib/autoconf/general.m4 (AC_ARG_VAR): Use AS_HELP_STRING instead of
15803 obsolete AC_HELP_STRING.
15804 (AC_HELP_STRING): AU_DEFUN to...

15810 2003-03-26 Derek Price <derek@ximbiot.com>
15812 * lib/autotest/general.m4: s/DEFAULT/DEFAULTS/ since it makes more
15813 sense. Verbosify the diversion definitions comment.

15853 (Automake): Automake 1.5+ no longer requires special tools to be
15854 present on the developer's host.

15858 * bin/autoheader.in (BEGIN): For DJGPP SHELL may not be set
15859 to a shell that can handle redirection or quoting correctly.

15868 * bin/ifnames.in: Add final newline to help and version messages.
15870 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Translate colons,
15871 to cope with DOS-style absolute paths, when constructing
15874 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS, _AC_OUTPUT_FILES):
15875 When constructing paths with IFS=:, quote the path. If we're
15876 constructing a DOS-style absolute path, we don't want to split it
15879 * tests/atspecific.m4 (AT_CHECK_CONFIGURE): Fix typo
15882 2003-02-25 Pavel Roskin <proski@gnu.org>

15890 2002-09-01 patch by replacing "test -n" with "test -z".
15891 This fixes a bug found by Jeff Painter and reported by Tom Epperly in
15892 <http://mail.gnu.org/archive/html/autoconf/2003-02/msg00139.html>.
15894 * doc/autoconf.texi (Shell Substitutions): test -n -> test -z,
15895 to fix a mismatch between example and discussion.

15899 * doc/autoconf.texi (Limitations of Builtins): Add notes on printf
15900 format starting with "-".
15902 2003-02-20 Alexandre Duret-Lutz <adl@gnu.org>
15904 * doc/autoconf.texi (Limitations of Make): `foo=bar make -e'
15905 is not portable inside Makefile.
15907 2003-02-20 Akim Demaille <akim@epita.fr>
15909 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): When
15910 compiler says yeah, but preproc says nope, compiler is right.
15911 Conversely, prompt the reader to send a bug report to the
15912 maintainers of the package, not of Autoconf.

15916 * bin/autoreconf.in (autoreconf_current_directory): Properly
15917 handle an empty aclocal.m4.

15922 $ac_prefix_program.
15925 2002-12-23 Paul Eggert <eggert@twinsun.com>
15927 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Define $1 to an
15928 innocuous variant befor including <limits.h> or <assert.h>. This
15929 works around a bug reported by Albert Chin: HP-UX 11i
15930 (and earlier versions) have a <limits.h> that declares
15931 gettimeofday and many other functions.
15933 2002-12-03 Paul Eggert <eggert@twinsun.com>
15937 * NEWS, configure.ac: Update version.
15939 * doc/fdl.texi: Upgrade to FDL version 1.2.
15941 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Use the function f
15942 nontrivially in main's body, so that f's external declaration is
15943 not optimized away in AIX. This should fix the bug reported by
15945 <http://mail.gnu.org/pipermail/autoconf/2002-November/014508.html>.
15947 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C),
15948 _AC_PROG_PREPROC_WORKS_IFELSE): Use <limits.h> if __STDC__ is
15949 defined, to support freestanding compilers. This should fix the
15950 bug reported by Momchil Velkov in
15951 <http://mail.gnu.org/pipermail/autoconf/2002-November/014490.html>.
15953 * doc/autoconf.texi (Obsolete Macros): Fix typos (insert empty
15954 arg, AC_DEFINE -> AC_DEFINE_UNQUOTED) in documentation for
15955 obsolete AC_CHECK_TYPE. The missing empty arg was reported

15959 * Makefile.maint (www-gnu): New macro.
15960 (standards.texi-url_prefix, make-stds.texi-url_prefix): Use it, as
15961 the location has moved.

15965 * bin/autom4te.in (at_flatten): rewritten to avoid M4 problem when
15966 \(.*\) match is too long and there is something more to be checked.
15967 <http://mail.gnu.org/pipermail/autoconf/2002-November/014524.html>
15969 2002-11-15 Akim Demaille <akim@epita.fr>

15985 Update from masters.
15987 2002-11-14 Akim Demaille <akim@epita.fr>
15989 * Makefile.maint: Sync with Bison, i.e.:
15990 (po-check): Scan .l and .y files instead of the
15991 .c and the .h files that they generate. This fixes the bug
15992 reported by Tim Van Holder in:
15993 <http://mail.gnu.org/pipermail/bison-patches/2002-November/001352.html>
15994 Look for N_ as well as for _. Try to avoid matching #define for
15998 2002-11-14 Akim Demaille <akim@epita.fr>
16000 * doc/autoconf.texi (C Compiler): Compiling several files at once.
16001 From Paul Eggert and Albert Chin-A-Young.
16003 2002-11-14 Akim Demaille <akim@epita.fr>
16005 * doc/autoconf.texi (C Compiler): Solitary backslashes.
16006 From Paul Eggert and Albert Chin-A-Young.
16008 2002-11-14 Kevin Ryde <user42@zip.com.au>
16010 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Initialize f=$1 rather
16011 than assigning in main, to avoid HP cc +O3 optimizing it away.
16013 2002-11-12 Peter Eisentraut <peter_e@gmx.net>
16015 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Add -q
16016 option. Process --recheck after parsing all options. Pass -q
16017 option to configure on --recheck.
16018 (AC_OUTPUT): Pass -q from configure to config.status.
16019 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Strip -q from
16020 arguments to record.
16021 * doc/autoconf.texi (config.status Invocation): Document
16022 config.status -q option.
16024 2002-11-07 Alexandre Duret-Lutz <adl@gnu.org>
16026 * bin/autoscan.in (scan_file): Scan Makefile.am too. Ignore
16027 Makefile.in if Makefile.am exists.
16028 (output): Strip `.am' from Makefiles. Don't
16029 output AC_CONFIG_FILES if no Makefiles were found.
16031 2002-11-07 Akim Demaille <akim@epita.fr>
16033 * Makefile.am (cvs_files): Add elisp-comp, mdate-sh.
16034 (local_updates): New.

16036 (local_updates): New.
16038 2002-11-06 Akim Demaille <akim@epita.fr>
16040 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY): Wrap the `f'
16041 declaration in extern "C" too.

16049 Reported by Ezra Peisach.
16051 2002-11-05 Akim Demaille <akim@epita.fr>
16053 * lib/autoconf/autoheader.m4 (_AH_TEMPLATE_OLD, _AH_VERBATIM_OLD):
16055 We _have_ to stop using the old compatibility scheme that tried to
16056 avoid useless backslashes because Libtool 1.4.3 contains a
16057 AC_DEFINE([error_t], [int],
16058 [Define to a type to use for \`error_t' if it is not
16059 otherwise available.])
16060 We _have_ to quote the single quote and backslashes with \. The
16061 old compatibility scheme saw that ` was backslashed, and therefore
16062 did not quote the single quote. Hence before this patch, Autoconf
16063 was not compatible with Libtool.
16065 2002-11-04 Paul Eggert <eggert@twinsun.com>
16067 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Set the following variables,

16084 (&autoreconf): here.
16085 ($help, $make, &parse_args, &autoreconf_current_directory):
16087 * doc/autoconf.texi (autoreconf Invocation): Adjust.
16089 2002-10-31 Bruno Haible <bruno@clisp.org>

16103 (AT_CHECK_ENV): Make sure the `state-ls.before file exists.
16105 2002-10-31 Akim Demaille <akim@epita.fr>
16107 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Use and display
16108 `$(MAKE)' instead of '${MAKE}' to emphasize that we refer to the
16109 Make variable, not a shell variable.
16110 Suggested by Bruno Haible.
16112 2002-10-31 Akim Demaille <akim@epita.fr>
16114 * bin/autom4te.in (load_configuration): Reject #args out of any
16117 2002-10-31 Akim Demaille <akim@epita.fr>
16119 * lib/autoconf/general.m4 (_AC_MSG_LOG_CONFTEST): New.
16120 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE, _AC_LINK_IFELSE)
16121 (_AC_RUN_IFELSE): Use it.
16122 * lib/autoconf/lang.m4 (_AC_COMPILER_OBJEXT):

16130 * doc/autoconf.texi (autom4te Invocation): Adjust.
16131 Suggested by Tim van Holder.
16133 2002-10-29 Paul Eggert <eggert@twinsun.com>
16135 * doc/autoconf.texi (Particular Functions): AC_FUNC_MALLOC and
16136 AC_FUNC_REALLOC check for compatibility with glibc, not POSIX.
16137 Problem reported by Bruno Haible.
16139 2002-10-29 Akim Demaille <akim@epita.fr>
16141 * doc/autoconf.texi (Header Templates): Put also in words what the
16142 pictures says to assist free style readers.

16454 Reported by Alexandre Duret-Lutz.
16456 * bin/autom4te.in (&parse_args): Do not prepend `--reload-state'

16461 (&up_to_date): If a file that was included according to the cache

16476 * lib/Autom4te/General.pm (&update_file): Use `verbose' to report
16477 if some file was changed instead of `print'.
16478 * bin/autoheader.in: Suggest AC_DEFINE with 3 args when needed.

16512 file name to enable parallel executions.
16513 From Sam Varshavchik.
16515 2002-10-08 Akim Demaille <akim@epita.fr>
16517 * bin/autoreconf.in (&autoreconf): Run autopoint before the first
16518 aclocal invocation, as Gettext macros might not be visible to
16520 Instead of blindly running autopoint, scan configure.ac (not the
16521 traces) for AM_GNU_GETTEXT_VERSION uses, as autopoint does.
16522 Reported by Paul D. Smith.
16524 2002-10-08 Paul Eggert <eggert@twinsun.com>
16526 Work around problems found when POSIXLY_CORRECT=1 is set.
16527 None of this seems to have anything to do with POSIX, really,
16528 but it's how Perl getopt works.
16529 * bin/autom4te.in (parse_args): Configure GetOpt with
16531 * doc/autoconf.texi (Invoking autom4te):
16532 --warning -> --warnings.

16554 * tests/torture.at (Configuring subdirectories): Be robust to
16555 users who use config.site to require for a cache: in this case,
16556 the two last configure runs, using two different sets of
16557 arguments, trigger a legitimate error.
16559 2002-09-28 Akim Demaille <akim@epita.fr>

16594 tests/autom4te itself.
16595 * lib/autoscan/Makefile.am: Include freeze.mk.
16596 (autoscan.list): New target --this file is no longer a source.

16601 * bin/autoscan.in (@kinds): Make them singular.
16603 (&init_tables): When --debug, report the list of rules to ease
16604 tracking changes in autoscan.list.
16605 * lib/autoscan/autoscan.list (function): Strip comments, sort.
16607 2002-09-28 Akim Demaille <akim@epita.fr>

16621 * bin/autoscan.in (&init_tables): Adjust.
16623 2002-09-28 Akim Demaille <akim@epita.fr>
16625 From now on, autoscan files must always map a macro name to a
16626 word: there is no `default' macro for autoscan.
16628 * bin/autoscan.in (&init_tables): Reject entries with no macro at
16630 * lib/autoscan/functions, lib/autoscan/headers: Make the macro

16653 the tmpdir must be created.
16654 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Have the tmp
16655 dir be in the build tree, instead of $TMPDIR.
16657 2002-09-27 Akim Demaille <akim@epita.fr>
16659 * bin/autoscan.in: Improve the comments.

16681 2002-09-25 Paul Eggert <eggert@twinsun.com>
16683 * BUGS (Interoperability bugs): New section. Mention libtool
16684 1.4.2, configure.ac, and AC_CONFIG_AUX_DIR interoperability bug.
16686 2002-09-24 Paul Eggert <eggert@twinsun.com>
16688 Fix a portability bug reported by Alexandre Duret-Lutz: Solaris 8
16689 make handles suffix-rules differently from GNU make.
16691 * bin/Makefile.am (SUFFIXES, .in): Remove.
16692 (autoconf autoheader autoreconf autoupdate ifnames autoscan autom4te):
16693 Move the body of the old .in rule here.
16695 2002-09-16 Akim Demaille <akim@epita.fr>
16697 i960 compilers create `b.out' files by default.
16698 Reported by Ralf Corsepius.
16700 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT): Remove b.out files.
16701 (_AC_COMPILER_EXEEXT_DEFAULT): Adjust to b.out.
16703 2002-09-13 Paul Eggert <eggert@twinsun.com>
16705 * doc/autoconf.texi (Particular Headers): Remove obsolete
16706 reference to `struct timezone' in the description of

16717 2002-09-13 Akim Demaille <akim@epita.fr>
16719 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Suggest
16720 reading config.log when the compiler is rejected.
16721 Suggested by Guido Draheim.
16723 2002-09-13 Akim Demaille <akim@epita.fr>
16725 * bin/autoreconf.in: Don't use Cwd::chdir, since in its internals
16726 (chdir_init) might hang when stat'ing mounted directories.
16727 Reported by Vance Shipley.
16729 2002-09-12 Akim Demaille <akim@epita.fr>
16731 * bin/autoscan.in (&parse_args): Pass a reference to the lists, not
16734 2002-09-12 Akim Demaille <akim@epita.fr>
16736 * doc/autoconf.texi (Defining Symbols): Present two different
16737 prototypes for AC_DEFINE and AC_DEFINE_UNQUOTED to emphasize the
16738 difference between 1 argument calls, and 2-3 argument calls.
16740 2002-09-12 Peter Eisentraut <peter_e@gmx.net>
16742 * doc/autoconf.texi: Review grammar and punctuation.
16744 2002-09-11 Paul Eggert <eggert@twinsun.com>
16746 * doc/autoconf.texi: Fix minor formatting, spelling, and
16748 (Defining Symbols): Explain that AC_DEFINE(var) defaults to 1, but
16749 AC_DEFINE(var,,description) does not; and the AC_DEFINE(var) case
16752 2002-09-11 Akim Demaille <akim@epita.fr>
16754 * doc/autoconf.texi (Questions): Rename as...
16756 (Defining Directories): New.
16758 2002-09-09 Akim Demaille <akim@epita.fr>
16760 * doc/autoconf.texi (Making testsuite Scripts): Update.
16761 Suggested by Nishio Futoshi.
16763 2002-09-09 Koji Arai <JCA02266@nifty.ne.jp>
16765 * doc/autoconf.texi (Making testsuite Scripts): Use `@@' where a
16766 plain `@' is wanted.
16768 2002-09-09 Akim Demaille <akim@epita.fr>
16770 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Keep the
16771 `duplicates', since the algorithm was too naive and could keep
16772 `--prefix=1 --prefix=2 --prefix=1' as `--prefix=1 --prefix=2', and
16773 keep `--prefix foo --prefix bar' as `--prefix foo bar'.
16774 Reported by Ralf Corsepius.
16775 * tests/torture.at (Configuring subdirectories): Exercise these
16778 2002-09-09 Akim Demaille <akim@epita.fr>
16780 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Use $srcdir when
16781 looking for a replacement file.
16782 * lib/autoconf/general.m4 (AC_CHECK_DECLS): Check that the
16783 directory is relative.
16784 * doc/autoconf.texi (Generic Functions): Clarify the replacement
16785 directory definition.
16786 Reported by Andreas Schwab and Jim Meyering.
16788 2002-09-06 Akim Demaille <akim@epita.fr>
16790 * doc/autoconf.texi (Setting Output Variables): Clarify what
16791 precious variables are.
16792 Suggested by Pontus Skoeld.
16794 2002-09-05 Akim Demaille <akim@epita.fr>
16796 * bin/Makefile.am (autoconf, autoheader, autoreconf, autoupdate)
16797 (ifnames, autoscan, autom4te): Since we don't only depend on
16798 configure.ac variables (such as VERSION etc.), but also on prefix
16799 and so forth, depend on Makefile, not configure.ac.
16800 Reported by Alexandre Duret-Lutz.
16801 * doc/autoconf.texi (Installation Directory Variables): Adjust.
16803 2002-09-05 Kevin Ryde <user42@zip.com.au>
16805 * doc/autoconf.texi (Limitations of Make): HP-UX trailing backslashes
16806 doesn't seem to be confined to ia64, just say "some versions".
16808 2002-09-04 Akim Demaille <akim@epita.fr>
16810 * Makefile.am, doc/Makefile.am: Remove pdf targets, handled by
16812 * Makefile.am (maintainer-clean-local): Remove.

16815 2002-09-03 Paul Eggert <eggert@twinsun.com>

16818 example for AC_CONFIG_COMMANDS_PRE. Problem reported by Marcus
16821 2002-09-03 Akim Demaille <akim@epita.fr>
16823 * configure.ac: Bump to 2.53d.
16824 * Makefile.am (AUTOMAKE_OPTIONS): Require 1.6c, i.e., CVS Automake
16825 as of today, on Automake's team suggestion.
16827 2002-09-03 Akim Demaille <akim@epita.fr>
16831 2002-09-02 Akim Demaille <akim@epita.fr>
16833 * bin/autom4te.in (parse_args): Don't honor AUTOM4TE_PATH and
16835 * configure.ac: Disable SITE_MACRO_DIR.
16837 2002-09-02 Jim Meyering <meyering@lucent.com>
16839 * doc/autoconf.texi (AC_SYS_POSIX_TERMIOS): Reflect renaming: s/am/ac/,
16840 i.e., change am_cv_sys_posix_termios to ac_cv_sys_posix_termios.
16841 Also, tweak grammar: s/make sure to/be sure to/.
16843 2002-09-02 Paul Eggert <eggert@twinsun.com>
16845 * doc/autoconf.texi (Limitations of Builtins): Explain why logical
16846 directory names are generally preferable to physical names.
16848 2002-09-02 Akim Demaille <akim@epita.fr>
16850 * lib/Autom4te/General.pm (&update_file): s/die/error/.
16851 Reported by Raja R. Harinath.
16852 * bin/autoheader.in, bin/autoreconf.in, bin/autoscan.in,
16853 * bin/autoupdate.in: Use error instead of die.
16855 2002-09-01 Paul Eggert <eggert@twinsun.com>
16857 * tests/mktests.sh (ac_exclude_egrep, au_exclude_egrep): Use
16858 ordinary shell concatenation rather than echo+tr+sed command that
16859 runs afoul of a long-line-related sed bug in Solaris 8.
16861 * bin/autoheader.in (parse_args): --warning -> --warnings.
16863 * bin/autoconf.as: Work even if "ls" outputs "FOO not found" to
16864 stdout, as traditional "ls" does.
16865 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT,
16866 _AC_COMPILER_EXEEXT_O): Likewise.
16867 * doc/autoconf.texi (Limitations of Usual Tools): Add "ls".
16869 * bin/autoconf.as: Add --prepend-include option. This patch was
16870 applied to bin/autoconf.in in the 2002-07-17 patch by Mark D. Roth,
16871 but bin/autoconf.in is generated automatically from bin/autoconf.as.
16873 * bin/autoconf.in, configure: Regenerate.
16875 * doc/autoconf.texi (Special Shell Variables): Mention
16876 ENV, MAIL, MAILPATH, PS1, PS2, PS4. Index PWD.
16878 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Unset ENV, MAIL,
16879 MAILPATH and set PS1, PS2, PS4 to default values, to work
16880 around bug in pre-3.0 UWIN ksh reported by Bruce Lilly.
16881 For LC_ALL etc, first try to set to "C" as POSIX requires and as
16882 the Autoconf documentation specifies; fall back to "unset" only if
16883 this fails. Use a shell for-loop for this rather than an m4 loop,
16884 to shorten the output script.
16886 2002-08-30 Paul Eggert <eggert@twinsun.com>
16888 * doc/autoconf.texi (Special Shell Variables): Mention POSIX
16889 1003.1-2001's requirements for CDPATH. Give a simpler workaround
16890 for the CDPATH problem. Document PWD.
16891 (Limitations of Builtins): Document the problem that "cd $foo" and
16892 "ls $foo" may refer to different directories in shells conforming
16893 to POSIX 1003.1-2001. Use PS1 rather than CDPATH for "unset"
16894 example, since the old example is now out of date.
16896 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Reject FOO if "cd
16897 FOO" and "ls FOO" talk about different directories; this catches
16898 problems when POSIX 1003.1-2001 "cd" fails due to symlink
16901 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Use AS_UNSET instead
16902 of rolling our own unset.
16903 (_AS_PREPARE): $as_unset CDPATH instead of AS_UNSETting it, since
16904 in practice we needn't worry about CDPATH if unset doesn't work.
16906 * Makefile.in, aclocal.m4, bin/Makefile.in,
16907 config/Makefile.in, doc/Makefile.in, lib/Makefile.in,
16908 lib/Autom4te/Makefile.in, lib/autoconf/Makefile.in,

16910 lib/emacs/Makefile.in, lib/m4sugar/Makefile.in, man/Makefile.in,
16911 tests/Makefile.in: Regenerate with Automake 1.6.3.
16913 * config/config.guess, config/config.sub, config/mkinstalldirs:
16916 * configure: Regenerate with self.
16918 2002-08-30 Kevin Ryde <user42@zip.com.au>

16928 2002-08-29 Akim Demaille <akim@epita.fr>
16930 * lib/Autom4te/General.pm (&xqx): New.
16931 (&xsystem): Use WIFEXITED and WEXITSTATUS instead of decoding $? by
16932 hand, which is not portable.
16934 * bin/autom4te.in: Use them.
16935 Use &error instead of die.
16936 * tests/m4sugar.at (m4_warn, m4_require: circular dependencies):
16939 2002-08-17 Paul Eggert <eggert@twinsun.com>
16941 * lib/autoconf/fortran.m4 (AC_PROG_F77): Remove fc from the
16942 default list of compilers to try, since it was long ago superseded
16943 by the ksh fc builtin. Suggested by Steven G. Johnson.
16945 2002-07-31 Alexandre Duret-Lutz <duret_g@epita.fr>
16947 * doc/autoconf.texi (Invoking autom4te): End the option table,
16948 fixing a bug introduced by the previous patch.
16949 (Limitations of Make): Add a 'target lookup' subentry in the
16950 'VPATH' entry. Rewrite all `make' occurences as `@command{make}'.
16952 2002-07-29 Mark D. Roth <roth@feep.net>
16954 * bin/autom4te.in: Remove --include-envvar and --site-macro-subdir
16955 options and use $AUTOM4TE_PATH.
16956 * doc/autoconf.texi: Remove documentation of autom4te
16957 --include-envvar and --site-macro-subdir options and document
16958 use of $AUTOM4TE_PATH.
16959 * lib/autom4te.in: Remove --include-envvar and --site-macro-subdir
16960 arguments from each language section.
16962 2002-07-29 Paul Eggert <eggert@twinsun.com>
16964 * doc/install.texi: Include copyright symbol in copyright notice.
16966 * Makefile.am (MAKEINFO): Remove; it's a user-specified macro.
16968 (AM_MAKEINFOFLAGS): New macro.
16969 * doc/Makefile.am (MAKEINFO, AM_MAKEINFOFLAGS): Likewise.
16970 * Makefile.am (INSTALL): Use the new macros.
16971 Use -o rather than --output, since "missing" does not grok --output.
16973 2002-07-25 Alexandre Duret-Lutz <duret_g@epita.fr>
16975 * doc/autoconf.texi (Limitations of Make): Escaped newlines in
16976 comments do not always work. Never trust the exit status of
16979 2002-07-24 Kevin Ryde <user42@zip.com.au>
16981 * doc/autoconf.texi (Limitations of Make, Making testsuite Scripts):
16982 Untabify, since tabs are not enjoyed by texi2dvi and makeinfo.
16984 2002-07-23 Paul Eggert <eggert@twinsun.com>
16986 * lib/m4sugar/m4sh.m4 (_AS_PATH_SEPARATOR_PREPARE):
16987 Use PATH="/nonexistent;.", not PATH=".;.", as FreeBSD ksh2002
16988 apparently treats PATH="nonexistent" as if it contained ".".
16989 Bug reported by Stefan `Sec' Zehl.
16991 2002-07-22 Alexandre Duret-Lutz <duret_g@epita.fr>
16993 * doc/autoconf.texi (Limitations of Make): Mention the special
16994 handling of the obj/ directory by BSD make.

17040 * lib/autoconf/functions.m4 (AC_FUNC_FORK): Don't set
17041 ac_cv_func_fork_works before running _AC_FUNC_FORK, do it if the
17042 latter was not run.

17259 This improves on an earlier suggestion by H. Peter Anvin.
17261 2002-05-16 Paul Eggert <eggert@twinsun.com>
17263 AC_FUNC_FNMATCH now tests only for POSIX compatibility.
17264 AC_FUNC_FNMATCH_GNU also tests for GNU extensions.
17265 Both macros now accept an optional source-dir arg.
17266 New macro AC_GNU_SOURCE to define _GNU_SOURCE.
17268 * NEWS: Document this.
17269 * doc/autoconf.texi (Particular Functions, UNIX Variants): Likewise.
17271 * lib/autoconf/functions.m4 (_AC_FUNC_FNMATCH): New macro.
17272 (AC_FUNC_FNMATCH): Use it. Test only for POSIX conformance,
17273 not for GNU extensions; this undoes part of the 2000-11-03 change,
17274 reverting to 2.13-compatible behavior.

17282 * lib/autoconf/headers.m4 (AC_HEADER_TIOCGWINSZ):
17283 Don't require AC_SYS_POSIX_TERMIOS. The test is unnecessary,
17284 and it causes a 'test' syntax error if it fails.
17285 Bug reported by Stephen Gildea.
17287 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
17288 If prototypes are supported, use them to check this at compile-time,
17289 instead of trying to check it at run-time. If we must do a run-time
17290 check, assume that setvbuf is standard when cross-compiling, as
17291 nonstandard setvbuf occurs only on ancient and unlikely hosts.
17292 Bug reported by Paul D. Smith.
17294 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Add optional
17295 argument specifying location of getloadavg.c. This removes a
17296 FIXME. This idea was taken from Jim Meyering's implementation in
17298 * doc/autoconf.texi (Particular Functions): Document this.
17299 Also, mention HAVE_NLIST_H rather than NLIST_STRUCT, since
17300 that's what the code does; this fixes a bug reported by
17303 2002-05-03 Akim Demaille <akim@epita.fr>
17305 * bin/autoreconf.in (autoreconf): Rewrite to use Gettext's
17306 autopoint instead of gettextize.
17307 ($uses_alocal): Rename as...
17308 ($uses_aclocal): this.
17309 * doc/autoconf.texi (autoreconf Invocation): Adjust.
17310 Suggested by Bruno Haible.

17314 * lib/m4sugar/m4sugar.m4 (m4_map_sep): New.
17316 2002-04-29 Paul Eggert <eggert@twinsun.com>
17318 * bin/autoreconf.in (autoreconf): Don't age aclocal.m4's input
17319 files to be 1 second older; just set them to be the same time.
17320 Also, sleep 1 second after the first aclocal, to work around
17321 problems with sub-second time stamps on the input files.
17323 2002-04-29 Thien-Thi Nguyen <ttn@gnu.org>
17325 * doc/autoconf.texi: Mention "set -e -x" lossage
17326 under node "Limitations of Builtins".

17332 From Christian Cornelssen.
17334 2002-04-29 Akim Demaille <akim@epita.fr>
17336 * tests/m4sh.at (LINENO): If testsuite itself is rewritten because
17337 of lack of $LINENO support, then the test will compare the $LINENO
17338 in testsuite vs. the lineno in the test file. This is wrong, of
17340 Be sure to protect it.
17341 Reported by Patrick Welche.
17343 2002-04-25 Akim Demaille <akim@epita.fr>
17345 * doc/autoconf.texi (Obsolete Macros): Typo.
17346 Reported by Vladimir Volovich.
17348 2002-04-25 Akim Demaille <akim@epita.fr>
17350 * bin/autoreconf.in (autoreconf): Don't let aclocal.m4 be older
17351 than some of the input files, hence, on the second run of aclocal,
17352 if some of its input are younger, make them older.
17353 Suggested by Paul Eggert.
17355 2002-04-25 Akim Demaille <akim@epita.fr>
17357 * doc/autoconf.texi (Limitations of Usual Tools): sed and `!'.

17363 and ac_subst_vars be sh variables containing the list of
17364 AC_SUBST_FILES'ed and AC_SUBST'ed identifiers. Output them in the
17366 (_AC_INIT_PREPARE): Use them to log them.
17367 (_AC_SUBST, _AC_SUBST_SED_PROGRAM): Remove.
17368 (AC_SUBST, AC_SUBST_FILE): Instead of buliding the
17369 _AC_SUBST_SED_PROGRAM, store the list of output files/variables in
17370 _AC_SUBST_FILES and _AC_SUBST_VARS.
17371 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Adjust.
17373 2002-04-24 Akim Demaille <akim@epita.fr>
17375 * bin/autoreconf.in (autoreconf): Run automake after autoconf and
17376 autoheader, so that automake does not complain about a missing

17435 importantly, this makes sure that the copyright notices appear in

17612 * doc/autoconf.texi (Assignments): Document the problem.
17614 2002-03-25 Alexandre Duret-Lutz <duret_g@epita.fr>
17616 * doc/autoconf.texi (Limitations of Make): Mention more issue
17617 about VPATH, overriding of macros in sub-makes, and handling of
17620 2002-03-21 Paul Eggert <eggert@twinsun.com>
17622 * doc/autoconf.texi (Here-Documents): Mention Solaris 8 dtksh
17623 problem with here-document buffer boundaries.
17625 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Unset ENV and BASH_ENV
17626 when reinvoking the shell, to work around problems with installers
17627 who put strange things like "cd" commands in their environments.
17629 2002-03-19 Akim Demaille <akim@epita.fr>
17631 * tests/semantics.at (AC_C_BIGENDIAN): s/unknow/unknown/.
17634 2002-03-19 Akim Demaille <akim@epita.fr>
17636 * bin/autoscan.in (scan_file): Specify the location in `&used'
17640 2002-03-19 Akim Demaille <akim@epita.fr>

17643 From Nishio Futoshi.
17645 2002-03-19 Akim Demaille <akim@epita.fr>
17647 * lib/m4sugar/m4sugar.m4 (m4_define_default, m4_fst, m4_map): New.
17649 2002-03-18 Paul Eggert <eggert@twinsun.com>
17651 * doc/autoconf.texi (Programming in M4sh): Add AS_MKDIR_P.
17652 (Limitations of Usual Tools): Add mkdir section.
17654 * lib/m4sugar/m4sh.m4 (_AS_MKDIR_P_PREPARE): New macro.
17655 (AS_MKDIR_P): Require it. Use mkdir -p if available, falling
17656 back on AS_DIRNAME to compute prefixes otherwise; this is
17657 roughly what mkinstalldirs does. That way, we need not have
17658 our own filename disassembler. The old disassembler did not
17659 work with Solaris 8 dtksh, which is ksh Version M-12/28/93d.
17661 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP):
17662 Create at_test_all by a series of assignments,
17663 not by a single assignment of a long string. The latter causes ksh
17664 version 11/16/88g to silently misbehave on OpenServer 5.0.6a,
17665 presumably because of a buffer overrun.
17667 2002-03-14 Paul Eggert <eggert@twinsun.com>
17669 * lib/autotest/general.m4 (at_times_skip):
17670 Renamed from at_times. Now a boolean.
17671 ksh93 Version M-12/28/93d doesn't like 'x=times; $x'; it
17672 says 'times: not found'.
17674 2002-03-14 Akim Demaille <akim@epita.fr>
17676 * bin/autoreconf.in (&study_gettextize): New.
17677 (&autoreconf): Handle newest gettextize.

17701 2002-03-11 Andreas Schwab <schwab@suse.de>

17704 does not do it if --with-lispdir is given.

17713 subdirectory should exist.
17715 2002-03-08 Akim Demaille <akim@epita.fr>
17717 * Makefile.am (AUTOMAKE_OPTIONS): 1.6.
17719 2002-03-08 Akim Demaille <akim@epita.fr>
17721 * bin/autom4te.in (&handle_m4): Do not foreach with `$_' as it
17722 aliases the actual variables, and modifications of the former
17725 2002-03-08 Akim Demaille <akim@epita.fr>
17727 * bin/autom4te.in (&handle_m4): Protect us from corrupted file
17728 because of C-c: have m4 output in tmp files, then mv them.
17730 2002-03-08 Akim Demaille <akim@epita.fr>

17751 * doc/autoconf.texi (AC_LIBOBJ vs. LIBOBJS): New.
17752 * lib/autoconf/general.m4 (AC_INIT): More informative error
17753 message for LIBOBJ.
17755 2002-03-04 Akim Demaille <akim@epita.fr>

17760 2002-03-04 Akim Demaille <akim@epita.fr>
17762 * doc/autoconf.texi (Transforming Names): Equality between target
17763 and host is irrelevant.
17764 (Specifying Names, Canonicalizing): Remove all references to the
17765 backward compatibility hooks. Rather, collect them all into...
17766 (Hosts and Cross-Compilation): this new section.
17767 * doc/install.texi (System Type): Ditto.
17768 * lib/autoconf/general.m4 (AC_CANONICAL_HOST): Explicitly state
17769 that `--host' implies cross-compilation.
17771 2002-03-04 Akim Demaille <akim@epita.fr>
17773 * doc/autoconf.texi (Evaluation Macros): New.
17774 * lib/m4sugar/m4sugar.m4 (m4_lquote): Remove, it is totally
17776 (_m4_foreach): Define the variant with immediate evaluation so
17777 that it contains exactly the items, not an expression which
17778 evaluation is the current item.
17779 (m4_re_string, m4_re_word): Don't over quote them.
17781 2002-03-04 Akim Demaille <akim@epita.fr>
17783 Instead of having stacking `shift's evaluated at the end, let
17784 `foreach' loops immediately evaluate them.
17786 * lib/m4sugar/m4sugar.m4 (m4_quote, m4_dquote): Use $@ rather than
17787 $*. This is the n-th time I change my mind, but hopefully this is
17790 (m4_text_wrap): Use m4_foreach, which is finally correct _and_
17792 (m4_foreach_quoted, m4_car_quoted, _m4_foreach_quoted): Remove, as
17793 it was only a hack for m4_text_wrap.
17794 (m4_car2): Remove, replaced by...
17796 (_m4_foreach): Adjust.
17797 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Adjust, and use
17798 m4_bpatsubst for clarification.

17849 Fix Autoconf PR/207:
17850 AC_PREFIX_PROGRAM fails with dashed program names
17852 * lib/autoconf/general.m4 (AC_PREFIX_PROGRAM): Just use a fresh

17889 2002-02-05 Akim Demaille <akim@epita.fr>
17891 * tests/Makefile.am (check_SCRIPTS): Use it, instead of WRAPPERS,

17913 * bin/autom4te.in (&parse_args): Implement `frozen files are
17914 optional are the sum of the previous files on the command line'.
17915 Also, pass `--reload-state=' on them, so...
17916 (handle_m4): don't.
17917 * lib/autom4te.in (Autotest, Autoconf): Rely on M4sh.
17918 (M4sh): Rely on M4sugar.

17949 Reported by Alexandre Duret-Lutz and Larry Schmitt.
17951 2002-01-28 Akim Demaille <akim@epita.fr>

17956 2002-01-28 Akim Demaille <akim@epita.fr>
17958 * lib/autotest/general.m4 (AT_INIT): Don't be ridiculous: adjust
17959 AUTOTEST_PATH *after* it was set.
17960 Don't put `.' in the PATH: the user should be precise and `./' if
17961 needed. In addition, given that the test suite does some `cd', if
17962 `.' is in the path, the `tested programs' sections will report
17963 programs found in the test suite's directory, while during the
17964 tests (performed in their own directory), these programs are no
17965 longer visible. In other words, the results is confusing and
17967 * tests/m4sh.at: Adjust: don't rely on `.' being in the PATH.

18013 * bin/autom4te.in (parse_args): Don't use
18014 Autoconf::General::getopt with non valid options.

18018 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Initialize

18036 * tests/Makefile.am (package.m4): New.
18037 EXTRA_DIST it since its a source.
18039 2002-01-06 Akim Demaille <akim@epita.fr>
18041 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Move the AC_SUBST
18042 of PACKAGE_NAME, PACKAGE_TARNAME, PACKAGE_VERSION, PACKAGE_STRING,
18043 and PACKAGE_BUGREPORT from here...
18044 (_AC_INIT_DEFAULTS): to here, since it is unrelated to the
18046 (_AC_INIT_PREPARE): AC_DEFINE these symbols.
18047 * lib/autotest/general.m4: Use AT_PACKAGE_*, not PACKAGE_*.
18048 (AT_INIT): No longer catch `^PACKAGE_(BUGREPORT|STRING)$'.
18049 * tests/tools.at (autoheader): Adjust.

18071 2001-12-14 Akim Demaille <akim@epita.fr>
18073 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): We cleaning up the
18074 trailing files, don't apply `-rf' to files which might not be
18075 created by configure (core, core.*, and *.core), but just `rm -f'.
18076 Suggested by Jonathan Kamens.
18078 2001-12-14 Aaron M. Ucko <amu@alum.mit.edu>

18118 Split the input line on spaces and then look for tokens.
18119 Now autoscan ceases to ask for AC_PROG_LEX for the package Bison

18126 * tests/autoreconf.in, tests/autom4te.in, tests/autoupdate.in:
18127 Remove, replaced by...
18128 * tests/wrappl.in: Be common for all the Perl executables.
18129 In particular autoscan and autoheader want -I.
18130 * configure.ac: Adjust.
18131 * lib/autoscan/headers: errno.h is portable.
18133 2001-11-26 Akim Demaille <akim@epita.fr>
18135 * bin/autoscan.in (used): New.
18138 2001-11-26 Akim Demaille <akim@epita.fr>
18140 * bin/autoscan.in (&scan_c_file): Better parsing of CPP
18142 (&scan_sh_file): Remove a duplicate pattern.
18143 (&check_configure_ac): Use long options.
18144 * lib/autoscan/headers (alloca.h): Check with AC_FUNC_ALLOCA.
18146 2001-11-26 Akim Demaille <akim@epita.fr>
18148 * bin/autoscan.in (scan_c_file): Fix the handling of C comments.
18149 Before, having a line containing the opening of a multi line
18150 comment made the whole line be ignored.
18152 2001-11-26 Akim Demaille <akim@epita.fr>
18154 * doc/autoconf.texi (Using an Autotest Test Suite): New.
18155 (testsuite Scripts): Be one of its subsection.
18156 (Autotest Logs): New.
18158 2001-11-26 Akim Demaille <akim@epita.fr>
18160 Test groups are now run two directories deeper.
18162 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Replace srcdir,
18163 top_srcdir and top_builddir with at_srcdir, at_top_srcdir and
18165 * lib/autotest/general.m4 (AT_INIT): Compute srcdir,
18166 top_srcdir, builddir and top_builddir.
18167 Use `at_*dir' relatively to the directory containing the
18168 suite, use `*dir' when relatively to the current group dir.
18170 2001-11-25 Joseph S. Myers <jsm28@cam.ac.uk>
18172 * doc/autoconf.texi, TODO, lib/autoconf/fortran.m4,
18173 lib/autoconf/functions.m4, lib/autoconf/headers.m4,
18174 tests/atgeneral.m4, tests/tools.at, tests/atspecific.m4: Fix
18177 2001-11-22 Alexandre Duret-Lutz <duret_g@epita.fr>
18179 * doc/autoconf.texi (Using System Type): Add an example of `case
18180 $host' usage so people quit using `case $target' everywhere.
18182 2001-11-22 Akim Demaille <akim@epita.fr>
18184 * doc/autoconf.texi (Installation Directory Variables): Englishoes
18185 spotted by Jim Meyering.
18187 2001-11-16 Paul Eggert <eggert@twinsun.com>
18189 This patch implements a `long double' suggestion by Oliver Kiddle.
18191 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C)): Make the array
18192 static, to catch errors if the value isn't known at compile-time
18193 and the compiler supports dynamic arrays. Change its name from
18194 `_array_' to `test_array' to avoid potential name clashes.
18195 (AC_C_LONG_DOUBLE): Make it a compile-time test, not a run-time
18196 test. Do not define HAVE_LONG_DOUBLE if `long double' is no
18197 better than double. Catch a bug in GCC 2.95.2 x86.
18198 * doc/autoconf.texi (C Compiler): Document the above.
18201 2001-11-13 Akim Demaille <akim@epita.fr>
18203 * tests/m4sh.at (LINENO): Protect from autom4te's substitution by
18205 * tests/tools.at: Don't protect dnl, AT_DATA_M4SH does.
18207 2001-11-13 Akim Demaille <akim@epita.fr>
18209 * lib/autotest/general.m4 (AT_INIT): After having run the test
18210 group, go back to the initial directory, not to at_suite_dir.
18212 2001-11-13 Akim Demaille <akim@epita.fr>
18214 * tests/atspecific.m4 (AT_DATA_M4SUGAR, AT_DATA_M4SH)
18215 (AT_DATA_AUTOCONF): Also protect @&t@ from autom4te.
18216 (AT_CHECK_AUTOCONF, AT_CHECK_AUTOHEADER): Pass no --include
18218 (AT_CHECK_CONFIGURE): Use absolute paths.
18219 (_AT_CHECK_AC_MACRO): Create aclocal.m4 with AC_STATE_SAVE in it.
18220 The problem is still the old one: there is no means in M4 (that I
18221 know about) to create a defining macro, because there is no means
18222 to create `$1' etc., therefore, the defining macro ``swallows''
18223 all the arguments meant to the defined macro.
18225 2001-11-13 Akim Demaille <akim@epita.fr>
18227 * tests/atspecific.m4 (AT_DATA_AUTOCONF): New.
18228 (AT_CONFIGURE_AC): Output the definition of AC_STATE_SAVE in
18230 * tests/aclocal.m4: Remove, as it is no longer used.
18232 2001-11-13 Akim Demaille <akim@epita.fr>
18234 * lib/autotest/general.m4: Change `tests?' into `groups?' in
18235 variable names when referring to a single test group, or to
18236 `suite' when referring to the whole test suite.
18237 `at_last_test' is removed: m4 compute at_format itself.
18238 (at_stdout, at_stder1, at_stderr): New variables.
18239 (AT_CHECK): Use them.
18241 2001-11-13 Akim Demaille <akim@epita.fr>
18243 * lib/autotest/general.m4 (AT_INIT): Be sure to put `.', relative,
18245 Create `testsuite.dir/003/run' instead of `testsuite.003'.
18246 Do it as soon as a test fails, don't wait till the end of the test
18248 Don't remove $as_me.[0-9]*, since these files no longer exist.
18250 2001-11-13 Akim Demaille <akim@epita.fr>
18252 * tests/tools.at: Use absolute paths, since we are no longer run
18255 2001-11-13 Akim Demaille <akim@epita.fr>
18257 Now that tests are running in their own private dir, there is no
18258 need to list the files to remove at the end of tests groups.
18260 * lib/autotest/general.m4 (_AT_CLEANUP_FILE, AT_CLEANUP_FILES):
18261 (AT_data_files, at_data_files): Remove.
18262 (AT_CLEANUP, AT_DATA): Simplify.
18264 Remove the group dir if !debug && !failed.
18265 * tests/atspecific.m4: Adjust.
18267 2001-11-13 Akim Demaille <akim@epita.fr>
18269 Start a new layout for Autotest: `testsuite' creates
18270 `testsuite.dir' in which the at-check-line etc. files are to be
18271 found, and `testsuite.dir/003' where the test group 3 is run.
18273 * lib/autotest/general.m4 (AT_INIT): at_tests_dir,
18274 at_check_line_file, at_format, at_test_normalized, at_group_dir
18276 Create the directories.
18277 Use absolute paths for at- files.
18278 (AT_CHECK): Adjust.
18280 2001-11-11 Michael Matz <matz@kde.org>
18282 * m4sugar.m4 (_m4_foreach): Make it linear instead quadratic.
18284 (m4_car): Properly quote arguments.
18286 2001-11-13 Akim Demaille <akim@epita.fr>
18288 * tests/aclocal.m4 (AC_STATE_SAVE): s/LIBOBJS/LIB@&t@OBJS/ to cope
18289 with stricter rules on LIBOBJS.
18291 2001-11-12 Paul Eggert <eggert@twinsun.com>
18293 * lib/autoconf/c.m4 (AC_C_PROTOTYPES): Define __PROTOTYPES too.
18294 * doc/autoconf.texi (C Compiler): AC_C_PROTOTYPES now defines
18297 2001-11-12 Akim Demaille <akim@epita.fr>
18299 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT): Use AC_CHECK_FUNCS.
18301 2001-11-12 Akim Demaille <akim@epita.fr>
18303 * lib/autoconf/c.m4, lib/autoconf/fortran.m4,
18304 * lib/autoconf/functions.m4, lib/autoconf/general.m4,
18305 * lib/autoconf/headers.m4, lib/autoconf/libs.m4,
18306 * lib/autoconf/programs.m4, lib/autoconf/specific.m4,
18307 * lib/autoconf/types.m4: When invoking AC_DEFINE and friends,
18308 specify to what the macro should be defined (typically to 1).
18310 2001-11-12 Akim Demaille <akim@epita.fr>
18312 * lib/autoconf/functions.m4 (AC_FUNC_STRTOD): AC_SUBST POW_LIB.
18315 2001-11-12 Akim Demaille <akim@epita.fr>
18317 * lib/autoconf/programs.m4 (_AC_PROG_LEX_YYTEXT_DECL): Use
18318 AC_TRY_EVAL to run $LEX, not AC_TRY_COMMAND. This validates the
18319 definition used by Automake where LEX is +/- "${missing} lex" and
18320 `missing' itself contains variables.
18322 2001-11-12 Akim Demaille <akim@epita.fr>
18324 * lib/autotest/general.m4 (AT_INIT): Push KILL at the end.
18325 Now that M4sh pushes BODY, the comments were output at the end of
18328 2001-11-08 Akim Demaille <akim@epita.fr>
18330 * bin/autoreconf.in (&autoreconf): Run aclocal before tracing, so
18331 that we can trace macros from aclocal.m4.
18332 Trace AC_PROG_LIBTOOL, not AM_PROG_LIBTOOL, since the latter is
18333 obsoleted, and redirect to the former anyway.
18334 Reported by Ralf Corsepius.
18336 2001-11-08 Akim Demaille <akim@epita.fr>
18338 * bin/autoreconf.in (&autoreconf): AC_CONFIG_SUBIDRS are to be
18339 processed only if present.
18340 * tests/torture.at (Configuring subdirectories): Use autoreconf
18341 instead of successive calls to autoconf.
18342 Add a nonexistent subdirectory to exercise the patch above.
18343 Reported by Ralf Corsepius.
18345 2001-11-08 Kevin Ryde <user42@zip.com.au>
18347 * doc/autoconf.texi (Limitations of Usual Tools): Note HP-UX cc
18348 doesn't accept .S files.
18350 2001-11-07 Akim Demaille <akim@epita.fr>
18352 * lib/m4sugar/m4sugar.m4 (m4_pattern_forbid): Accepts $2.
18353 * lib/autoconf/general.m4 (AC_INTI): Forbid LIBOBJS.
18354 (_AC_LIBOBJ): s/LIBOBJS/LIB@&t@OBJS/.
18355 * bin/autom4te.in (warn_forbidden): New.
18356 (handle_output): Use it.
18357 Read m4_pattern_forbid with messages.
18359 2001-11-05 Akim Demaille <akim@epita.fr>
18361 * bin/autom4te.in (--normalize): Remove.
18362 * lib/autom4te.in: Adjust.
18364 2001-11-05 Akim Demaille <akim@epita.fr>
18366 * tests/Makefile.am (testsuite): Rename this target as...
18367 ($(TESTSUITE)): this.
18370 2001-11-05 Alexandre Duret-Lutz <duret_g@epita.fr>
18372 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): When removing
18373 the --prefix option, also remove it's argument.
18375 2001-11-05 Akim Demaille <akim@epita.fr>
18377 * doc/autoconf.texi (testsuite Invocation): Update.
18378 (Writing testsuite.at): Update.
18380 2001-11-03 Akim Demaille <akim@epita.fr>
18382 * doc/autoconf.texi: s/@code/@command/ where appropriate.
18384 2001-11-03 Akim Demaille <akim@epita.fr>
18386 * lib/Autom4te/General.pm: (&catfile, &canonfile)
18387 (&file_name_is_absolute): New, wrappers around routines from
18389 Use and export them.
18390 (&find_configure_ac): Optionally take a directory where to look at.
18391 * bin/autoreconf.in (&parse_args): Trim the configure.ac part of
18393 Default @ARGV to `.', not find_configure_ac.
18394 (&autoreconf): Argument is a directory.
18395 Trace AC_CONFIG_SUBDIRS and schedule the subdirs for autoreconf'ing.
18396 * doc/autoconf.texi (autoreconf Invocation): Update.
18398 2001-11-03 Akim Demaille <akim@epita.fr>
18400 * lib/Autom4te/General.pm (@export_vars, @export_subs)
18401 (@export_forward_subs): New.
18402 Add basename, dirname, and fileparse.
18404 * bin/autoreconf.in (&autoreconf): Fix call to fileparse.
18405 Don't look for aclocal flags if we already know aclocal is not
18407 Move aclocal.m4t only if it exists.
18408 Reported by Ezra Peisach.
18410 2001-11-03 Akim Demaille <akim@epita.fr>
18412 * bin/autoreconf.in (&parse_args): Work only on the configure.ac
18413 passed on command line, defaulting to ./configure.ac if present.
18414 (&maybe_autoreconf, File::Find): Remove, unused.
18415 (&autoreconf): If autoconf is not used, don't try to trace.
18417 2001-11-02 Akim Demaille <akim@epita.fr>
18419 * configure.ac: Bump to 2.52g.
18421 2001-11-02 Akim Demaille <akim@epita.fr>
18425 2001-11-02 Akim Demaille <akim@epita.fr>
18427 * config/config.guess, config/config.sub, doc/standards.texi:
18428 * config/lispdir.m4: Update from masters.
18429 * configure.ac: Bump to 2.52f.
18431 2001-11-02 Akim Demaille <akim@epita.fr>
18433 * bin/autoreconf.in (&autoreconf): Set `$aclocal_flags' to ''.
18434 Don't run aclocal when aclocal.m4 is not from aclocal.
18436 Don't run libtoolize and gettextize if --install is not given.
18438 2001-11-01 Paul Eggert <eggert@twinsun.com>
18440 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): _AS_CR_PREPARE needs to
18441 be invoked before _AS_LINENO_PREPARE.
18442 (_AS_LINENO_PREPARE): Use as_cr_digits and as_cr_alnum rather
18443 than character ranges.
18445 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Fix NLS before
18446 invoking AS_BASENAME. Set the locale variables to 'C' if
18447 possible, as POSIX requires this to get the traditional
18449 * doc/autoconf.texi (Special Shell Variables): Describe the above.
18451 2001-10-31 Paul Eggert <eggert@twinsun.com>
18453 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): Do not surround body
18454 with {}, as that triggers a bug in Bash 2.05.
18456 (_AS_LINENO_PREPARE): Use Sed rather than
18457 Awk. Fix the sed prepass to work even if there are multiple
18458 instances of $LINENO on the same line. Do not substitute for
18459 other variables like $LINENOT. Do not check file dates; such a
18460 check is unreliable on sufficiently fast machines, and removing
18461 the check makes the code simpler and more reliable. Check for
18462 output and chmod failures.
18464 * doc/autoconf.texi (Special Shell Variables): Document
18467 2001-10-31 Akim Demaille <akim@epita.fr>
18469 * tests/Makefile.am (atconfig): Remove this target, Automake
18472 2001-10-31 Akim Demaille <akim@epita.fr>
18474 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Do not
18475 AC_CONFIG_FILES(atlocal) as it means a file atlocal.in *must* be
18476 provided, while it is optional.
18477 * configure.ac: Adjust.
18479 2001-10-26 Paul Eggert <eggert@twinsun.com>
18481 * NEWS, README, configure.ac, lib/Autom4te/General.pm,
18482 lib/Autom4te/Struct.pm:
18483 Require Perl 5.005_03 instead of just 5.005, as some tests fail
18486 * doc/autoconf.texi (Special Shell Variables): Document some
18487 more LINENO gotchas, particularly with respect to the Awk+Sed hack.
18489 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): New macro.
18490 (_AS_LINENO_PREPARE): Use it instead of shell eval, since
18491 eval $LINENO is not portable in practice.
18493 2001-10-24 Akim Demaille <akim@epita.fr>
18495 * lib/Autom4te/General.pm (backname): New.
18497 2001-10-24 Akim Demaille <akim@epita.fr>
18499 * m4/: Remove, merged into...
18502 2001-10-23 Tim Van Holder <tim.van.holder@pandora.be>
18504 * doc/autoconf.texi (Shellology): Mention the problems with bash
18505 2.05's use of ANSI quoting in its `set' builtin.
18507 2001-10-22 Paul Eggert <eggert@twinsun.com>
18509 * lib/autoconf/functions.m4 (AC_FUNC_STRERROR_R):
18510 Rename ac_cv_func_strerror_r_works to ac_cv_func_strerror_r_char_p,
18511 and rename HAVE_WORKING_STRERROR_R to STRERROR_R_CHAR_P, since
18512 POSIX decided to standardize on the int flavor of strerror_r.
18513 Always do char* test, as there's no reason not to.
18514 Assign to a char* var, to catch strerror_r that returns int*.
18516 * doc/autoconf.texi (Particular Functions):
18517 Document the above changes. Also, document the fact that
18518 AC_FUNC_STRERROR_R defines HAVE_DECL_STRERROR_R.
18520 * NEWS: Mention HAVE_WORKING_STRERROR_R -> STRERROR_R_CHAR_P.
18522 2001-10-20 Akim Demaille <akim@epita.fr>
18524 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): The name of
18525 the executable was missing from the log.
18527 2001-10-20 Akim Demaille <akim@epita.fr>
18529 * lib/Autom4te/General.pm (&update_file): If destination is
18530 unchanged, remove the source.
18531 (&up_to_date_p): Don't be verbose, be debug.
18532 * bin/autoreconf.in: No longer support --m4dir.
18533 (&autoreconf): Display the full path of the configure.ac we are
18535 Trace it only once.
18536 Be sure to honor --force with gettextize.
18537 Always run aclocal.
18538 * doc/autoconf.texi: Adjust.
18540 2001-10-20 Akim Demaille <akim@epita.fr>
18542 * bin/autoheader.in ($localdir, $m4, $SIMPLE_BACKUP_SUFFIX):
18544 * bin/autoreconf.in (&autoreconf): Do not run gettextize when
18545 `intl' is already present, as it refuses unless --force.
18546 (&parse_args): Use -I, --include instead of the old Autoconf
18548 ($localdir, $autoconf_dir): Remove.
18550 (&maybe_autoreconf): New, to preserve $_ for File::Find.
18552 2001-10-19 Jens Petersen <petersen@redhat.com>
18554 * lib/autoconf/programs.m4 (AC_PROG_AWK): Prefer gawk to mawk.
18555 * doc/autoconf.texi (Particular Programs): Likewise.
18557 2001-10-19 Akim Demaille <akim@epita.fr>
18559 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Name the generated
18560 file in @configure_input@.
18561 Don't mention `automatically' in addition to `generated'.
18562 * tests/torture.at (#define header templates): Adjust.
18564 2001-10-19 Akim Demaille <akim@epita.fr>
18566 * lib/emacs/autoconf-mode.el, lib/emacs/autotest-mode.el: In a
18567 comment, explain how to install automatic mode selection.
18570 2001-10-19 Ezra Peisach <epeisach@zif.mit.edu>
18572 * bin/autoreconf.in (autoreconf): Display the path to the
18573 configure.ac being studied.
18575 2001-10-18 Paul Eggert <eggert@twinsun.com>
18577 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Cast sizeof to unsigned
18578 long, to work around a bug in the HP C compiler version HP92453-01
18581 * lib/m4sugar/m4sh.m4 (AS_DIRNAME): Use 'dirname' if that works.
18582 (AS_BASENAME_EXPR): New macro.
18583 (AS_BASENAME_SED): Do not assume GNU sed semantics.
18584 (AS_BASENAME): Use 'basename' if that works; then try 'expr';
18585 and fall back on 'sed' only if the other two fail. This makes
18586 AS_BASENAME act more like AS_DIRNAME.
18587 (as_me): Shell-quote the argument of AS_BASENAME, in case $0
18588 contains white space.
18589 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR):
18590 Use AS_DIRNAME, since I think it's now DOS-friendly.
18591 * tests/m4sh.at (DIRNAME_TEST): New arg $3.
18592 Allow "dirname //FOO" to return either / or //, as POSIX allows
18595 2001-10-10 Akim Demaille <akim@epita.fr>
18597 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Recognize
18598 `a_out.exe' for OpenVMS 7.1, DEC C 5.5 compiler, via GNV.
18601 2001-10-10 Akim Demaille <akim@epita.fr>
18603 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N_PREPARE): m4_defun, not
18604 m4_define, since...
18605 (_AS_ECHO_N): AS_REQUIREs it.
18607 2001-10-10 Akim Demaille <akim@epita.fr>
18609 * lib/autoconf/general.m4 (_AC_INCLUDES_DEFAULT_REQUIREMENTS)
18610 (AC_INCLUDES_DEFAULT): Move to...
18611 * lib/autoconf/headers.m4: here.
18612 * lib/autoconf/types.m4: Comment changes.
18613 * doc/autoconf.texi: Specify where the default includes are used
18614 in the macro prototypes.

19081 * tests/m4sh.at: Ensure that AS_DIRNAME handles '/', '//' and '///'
19083 Add test for AS_BASENAME.
19084 * lib/m4sugar/m4sh.m4: Fix AS_BASENAME so that it passes the previous
19085 added test. It now correctly handles /1/2/3/, returning '3' not ''.
19086 Added AS_BASENAME_SED to make the interface the same as AS_DIRNAME.
19087 * tests/base.at: Fixed the expected responses. The old ones were
19089 * lib/autoconf/general.m4: Fixed AC_PREFIX_PROGRAM, it now behaves as
19090 the documentation claims it should (and how it behaved in 2.13).
19092 2001-09-18 Akim Demaille <akim@epita.fr>
19094 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): No INIT-CMDS in
19095 the AC_CONFIG_COMMANDS invocation.
19096 This also solves the name clash problems.
19097 Don't set the package's ID.
19098 * lib/m4sugar/Makefile.am (version.m4): Revamp.
19099 No longer to be shipped.
19100 (version.in): Remove.
19101 * lib/m4sugar/m4sugar.m4, lib/autoconf/general.m4,
19102 * lib/autoconf/status.m4: Adjust.
19103 Use `m4_PACKAGE_STRING'.
19104 * lib/autotest/general.m4 (AT_INIT): N-th signature change: now
19105 the only optional argument is the name of the test suite.
19106 Expect `package.m4' to define the package signature.
19107 * lib/autom4te.in (Autotest): Add `package.m4?'.
19108 * tests/Makefile.am (package.m4): New.
19109 * tests/suite.at: ifnames is a victim.
19111 2001-09-18 Akim Demaille <akim@epita.fr>
19113 * lib/autom4te.in (Autoconf): Preselect AM_CONDITIONAL,
19114 AC_LIBSOURCE, AC_CONFIG_FILES.

19122 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):
19123 Allow expression to return any value that can fit into unsigned long
19124 (not int, as before). Check for output errors.
19126 2001-09-17 Bruno Haible <haible@ilog.fr>
19128 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):
19129 Always include <stdio.h> and <stdlib.h>. Evaluate
19130 the expression in an extra function before these includes. Call
19131 fprintf "%d" only after ensuring the argument is of type 'int'.
19132 Reported by Wayne Chapeskie <waynec@spinnaker.com>.
19134 2001-09-17 Paul Eggert <eggert@twinsun.com>
19136 Fix bug reported by Paul Townsend on AIX 4.3.3.0 with CFLAGS=-O4
19137 or CFLAGS=-O5. In that case, the linker has a relaxed view of
19138 fatal errors, and AC_CHECK_LIB causes it to include libraries even
19139 when they don't exist.
19141 * lib/autoconf/headers.m4 (AC_HEADER_DIRENT): Use AC_SEARCH_LIBS,
19142 not AC_CHECK_LIB, so that we don't use -ldir or -lx if we don't
19145 * lib/autoconf/specific.m4 (AC_ISC_POSIX): Replace the old, crufty
19146 version with the version used by fileutils 4.1, except use
19147 AC_SEARCH_LIBS, not AC_CHECK_LIB, so that we don't use -lcposix if

19152 2001-09-13 Akim Demaille <akim@epita.fr>

19192 * lib/autotest/general.m4 (AT_INIT): Create and remove
19193 `$as_me.[0-9]+' instead of `debug-[0-9]+.sh', so that multiple
19194 test suites can cohabit.
19196 2001-09-13 Akim Demaille <akim@epita.fr>
19198 * tests/mktests.sh: Don't output banners for empty test files.

19250 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Don't pass

19253 * lib/autoconf/programs.m4 (AC_SHELL_PATH_WALK): Use PATH_SEPARATOR.

19297 to avoid GCC warnings.
19300 2001-09-05 Akim Demaille <akim@epita.fr>
19302 * bin/autom4te.in: --language is -l, not -s.
19304 2001-09-05 Akim Demaille <akim@epita.fr>
19306 Be ready to handle filenames as stupid as `dnl.at', for if even
19307 the maintainer is dumb enough to do that...
19309 * lib/autotest/general.m4 (AT_SETUP, AT_LINE): Demonstrates your
19310 excellence in M4 quotation: consider `__file__' is active.
19312 And BTW, when invoking m4, pass the --include in the right order:
19315 * bin/autom4te.in, bin/autoupdate.in: Use reverse when kingtal to

19343 New, extracted from main.
19344 Use IO::File wherever possible.
19345 (input.m4): Be constant, use -I instead of hard coding $tmp.
19346 Therefore be a quoted heredoc.
19347 Don't invoke `_au_disable', since ac was not loaded, but just

19375 2001-08-31 Akim Demaille <akim@epita.fr>
19377 * doc/autoconf.texi (Quadrigraphs): Document `@&t@'.
19378 (testsuite Scripts): There is no such thing as `atconfig.in'.
19379 And actually one diagram is missing: test suite runtime.
19381 2001-08-31 Akim Demaille <akim@epita.fr>
19383 * lib/Autom4te/General.pm (&find_file): Browse the includes in the
19386 2001-08-31 Akim Demaille <akim@epita.fr>
19388 * bin/autoupdate.in (@include): `installcheck' revealed the path
19389 to m4sugar was lacking!
19391 2001-08-31 Akim Demaille <akim@epita.fr>
19393 * man/Makefile.am (.x.1): We really have to pass
19394 autom4te_perllibdir.

19404 * bin/autom4te.in (&parse_args): Strip `.' from `@include'.
19405 * bin/autoupdate.in: Use --include, -I, and --force, -f, too.
19406 Use directly autom4te, not autoconf.

19448 Drop AC_MACRODIR dead for real.
19449 * tests/atspecific.m4 (AT_CHECK_AUTOHEADER): Now autoheader says
19450 `autoheader: `config.hin' is created'.
19451 * tests/tools.at (Syntax of the Perl scripts): Check autoheader.
19453 2001-08-31 Akim Demaille <akim@epita.fr>
19455 * bin/autoheader.in: Rewrite in Perl.

19458 2001-08-31 Akim Demaille <akim@epita.fr>
19460 * bin/autoconf.in (--include, -I): New option.
19461 Map --localdir, --autoconf-dir onto it.
19462 Forward autom4te's options instead of interpreting them.
19463 * bin/autoconf.in, bin/autoheader.in (AC_MACRODIR, autoconf_dir):
19464 There is no such envvar since the inception of autom4te.cfg.
19465 * bin/autom4te.in (&parse_args): Uniquify `@include'.
19466 * bin/autoupdate.in: Adjust, and perform more control.

19468 * tests/autoconf: Dittowise.
19470 2001-08-31 Akim Demaille <akim@epita.fr>

19485 Pass `autoconf_dir' via options, not via invisible envvars.
19486 * lib/Autom4te/General.pm (&find_peer): Remove.
19487 * lib/autotest/general.m4 (AT_INIT): `AUTOTEST_PATH=a:b' gives
19488 `abuild:asrc:bbuild:bsrc', not `abuild:bbuild:asrc:bsrc'.
19489 * man/Makefile.am: Let help2man rely on PATH instead of trying to
19490 find the executables for it.
19491 * tests/Makefile.am: Major cleanup. Too lazy to document...
19492 * tests/atlocal.in: Remove all the obscure envvar manipulations.
19494 * tests/atspecific.m4, tests/tools.at: Passing --localdir is
19495 indeed related to running the test suite, while passing
19496 --autoconf-dir and others is related to running non installed
19497 Autoconf executables. So don't do that, leave it to...
19498 * tests/autoconf, tests/autoheader, tests/autom4te, tests/autoupdate,
19499 * tests/autoscan: New.
19500 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): Don't

19516 * bin/autom4te.in (&handle_output): s/@__@/@&t@/.
19517 Suggested by Paul Eggert.
19519 2001-08-29 Akim Demaille <akim@epita.fr>
19521 * Makefile.maint (do-po-update): Wget refuses to overwrite files:
19522 download in a tmp dir.
19524 2001-08-29 Akim Demaille <akim@epita.fr>
19526 * lib/autotest/general.m4: s/AT-devnull/devnull/ since there are

19538 * bin/autoconf.in: Simplify and adjust.
19539 * tests/Makefile.am (AUTOMAKE): Use --set.
19540 * tests/atlocal.in: Adjust.

20063 2001-08-11 Alexandre Duret-Lutz <duret_g@epita.fr>
20065 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Handle ACTION-IF-TRUE,
20066 ACTION-IF-FALSE, and ACTION-IF-UNKNOWN.
20067 * doc/autoconf.texi (C Compiler Characteristics): Update
20068 documentation for AC_C_BIGENDIAN.
20070 2001-08-11 Alexandre Duret-Lutz <duret_g@epita.fr>
20072 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Guess endianness by grep'ing
20073 magic values from an object file when cross-compiling.
20074 Based on code by Guido Draheim <Guido.Draheim@gmx.de>.
20076 2001-08-10 Akim Demaille <akim@epita.fr>
20078 * bin/autom4te.in (&handle_output): Don't use `grep' with side
20080 Suggested by Russ Allbery.
20082 2001-08-10 Ralf Corsepius <corsepiu@faw.uni-ulm.de>
20084 * lib/autoconf/general.m4 (_AC_OUTPUT_SUBDIRS): Propagate the
20085 current $prefix to the sub-configures.
20087 2001-08-09 Tim Van Holder <tim.van.holder@pandora.be>
20089 * lib/autoconf/lang.m4: Ignore *.xSYM when looking for an executable
20090 extension (needed on BeOS). Reported by Guido van Rossum.
20092 2001-08-09 Akim Demaille <akim@epita.fr>
20094 * bin/autom4te.in ($icache): Load it only if older than autom4te.
20096 2001-08-07 Akim Demaille <akim@epita.fr>
20098 * lib/autotest/general.m4 (AT_INIT): All the `at-*' are to be
20100 (at-setup-line): Huh? Be a variable `at_setup_line', not a file.
20101 No need to remove the files before and after the each test, before
20102 each test and at the end of the suite is enough.
20103 Display only the children `times', not the shell's.
20104 If the test failed or was skipped, at-times is not available.
20106 2001-08-07 Akim Demaille <akim@epita.fr>
20108 Always produce testsuite.log, including when there are no
20109 failures. This helps getting information on skipped tests, and
20110 duration of the tests. Err, implement the latter btw.
20112 * lib/autotest/general.m4 (AT_INIT): Set up fd 6 for the log.
20113 Dump information on the first run of each test.
20114 (AT_CLEANUP): Create `at-times' containing the duration of the
20117 2001-08-07 Akim Demaille <akim@epita.fr>
20119 The use of `dumpstat' revealed that `len' was used although it
20120 should not. m4_text_wrap was using it, but in the Autoconf world
20121 where it is legal. Hence (i) test M4sh in its own world, not
20122 Autoconf's, and (ii), ahem, fix the bug :)
20124 * lib/autotest/general.m4: Be sure the set good quotes, as tracing
20125 does not like `' instead of [].
20126 (AT_INIT): Forbid `^_?AT_'.
20127 And don't output such tokens.
20128 * tests/Makefile.am (CLEANFILES): Add `script', `script.s4g',
20129 `script.as', and `autom4te.cache'.
20130 Remove `empty' and `macro' which are no longer used.
20131 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): New.
20132 * tests/m4sugar.at: Use it.
20133 * lib/m4sugar/m4sugar.m4: Use `m4_len' not `len'.
20135 2001-08-07 Akim Demaille <akim@epita.fr>
20137 * bin/autoconf.in, bin/autoheader.in: --force, -f is a new option.
20139 2001-08-07 Alexandre Duret-Lutz <duret_g@epita.fr>
20141 * bin/autom4te.in (handle_output): Typo in quadrigraph substitution.
20143 2001-08-04 Akim Demaille <akim@epita.fr>
20145 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA, AC_FUNC_ERROR_AT_LINE)
20146 (AC_FUNC_FSEEKO, AC_FUNC_OBSTACK): Use AC_LANG_IFELSE, not
20148 * lib/autoconf/headers.m4 (AC_HEADER_MAJOR): Likewise.
20149 * lib/autoconf/fortran.m4 (_AC_LANG_PROGRAM_C_F77_HOOKS)
20150 (AC_F77_MAIN): Likewise.
20152 2001-08-04 Akim Demaille <akim@epita.fr>
20154 Don't rely on M4sugar outputting the patterns in files, since we
20155 might process the output _without_ running m4, hence without these
20158 * lib/m4sugar/m4sugar.m4 (m4_init): No need for `m4_tmpdir'.
20159 * bin/autom4te.in (@Request::includes): Remove, unused.
20160 (@Request::source): Rename as...
20161 (@Request::input): this.
20162 (@preselect): Add `m4_pattern_forbid' and `m4_pattern_allow'.
20163 (&handle_output): Fetch the patterns from the traces.
20164 `$forbidden' and `$allowed' are constant: use m//o.
20165 (&handle_m4): M4sugar no longer wants `m4_tmpdir'.
20166 (m4_pattern_forbid, m4_pattern_allow): Adjust for tracing only.
20168 2001-08-04 Akim Demaille <akim@epita.fr>
20170 `autoconf && autoheader' is sped up. Now, speed up `autoheader &&
20171 autoconf', i.e., in addition to caching traces, cache the output.
20173 * bin/autom4te.in (Request::cache): Rename as...
20174 (Request::id): this.
20175 ($cache, $icache, $tcache, $ocache): New.
20176 (&handle_m4): Save M4 output in the cache instead of $tmp.
20177 (&handle_output): Adjust.
20178 (&up_to_date_p): Check that the output cache is up to date too.
20179 (top level): Run `&handle_m4' iff force or the cache is invalid.
20180 Run `&handle_output' if the output cache is more recent.
20182 2001-08-04 Akim Demaille <akim@epita.fr>
20184 * bin/autom4te.in ($force): New.
20185 (&parse_args, &print_usage): -f, --force is a new option.
20186 (&handle_output): CPP directives might have spaces after `#'.
20187 (&parse_args): The first file only can be frozen.
20189 2001-08-04 Akim Demaille <akim@epita.fr>
20191 Don't let autom4te compute the `include' traces several times:
20192 first check that the trace cache file is up to date, and then
20193 compare its timestamp with that of the output.
20195 * bin/autom4te.in, bin/autoupdate.in, bin/autoscan.in: Normalize
20196 the preamble. Don't require 5.005 as Autom4te::General does it,
20197 and better yet (use `use', not `require'!).
20198 * lib/Autom4te/Struct.pm: Rename the last occurrences of
20199 Class::Struct as Autom4te::Struct.
20200 * lib/Autom4te/General.pm (File::stat): Use it.
20201 (&mtime): New, export it.
20202 * bin/autom4te.in: Use it.
20203 Declare `$req' is invalid if it is outdated.
20204 Don't declare it valid before saving it if something went wrong.
20206 2001-08-04 Akim Demaille <akim@epita.fr>
20208 Autom4te shall not encode Autoconf data, and preselecting traces
20209 must be proposed to the users.
20211 * bin/autom4te.in (@required_trace): Remove.
20213 (&parse_args, &print_usage): -p, --preselect is a new option.
20214 (&up_to_date_p): Adjust.
20215 * bin/autoconf.in: Preselect some Autoconf macros.
20217 2001-08-04 Akim Demaille <akim@epita.fr>
20219 * tests/tools.at (autoconf --trace: user macros): Check traces on
20220 macros invoked without arguments, and macros invoked with multiple
20223 2001-08-03 Alexandre Duret-Lutz <duret_g@epita.fr>
20225 * bin/autom4te.in (handle_traces): Fix rewriting of traces without
20228 2001-08-03 Akim Demaille <akim@epita.fr>
20230 * bin/autoconf.in ($@): Work around the usual sh bug.
20233 2001-08-03 Akim Demaille <akim@epita.fr>
20235 Clean up the handling of the M4 builtins tracing exception.
20237 * bin/autom4te.in (Request::request): Don't complete M4 builtins

20240 (@m4_builtin): this.
20241 (%m4_builtin_alternate_name): New.
20242 (&parse_args): Complete the trace requests with alternate names.

20254 (m4_divert_pop): Dump the whole diversion stack when a diversion
20256 * bin/autom4te.in (&handle_output): Remember of the first
20257 occurrence of a possibly undefined macro, not the last.
20258 Complain about the possibly undefined macros in the same order as
20259 the appear in the output.
20260 * lib/autoconf/Makefile.am (autoconf.m4f): List its dependencies.
20261 * tests/tools.at (autoconf: forbidden tokens, basic)
20262 (autoconf: forbidden tokens, exceptions): No longer sort
20263 autoconf's stderr, as it is now deterministic.
20264 Check that `dnl' is caught.

20285 * bin/autoconf.in, bin/autom4te.in, bin/autoupdate.in: Remove your
20286 `END', as `Autom4te::General::END' will be triggered.
20287 * bin/autoupdate.in, bin/autoscan.in: Improve error messages accuracy.
20288 * bin/autoupdate.in (File::Compare, File::Copy): Use them instead of
20289 system to run `mv', `rm', and `cmp'.
