6076 (AT_INIT) <PARSE_ARGS_END>: ...here, since -k always takes
6078 <DEFAULTS>: Delay computation of variables based on $at_dir...
6079 <PREPARE_TESTS>: ...to here, since -C can change $at_dir.
6080 <TESTS>: Re-invoke via absolute name, since -C may be in effect.
6081 <PARSE_ARGS>: Parse new option.
6082 <HELP_TUNING>: Document it.
6083 * tests/autotest.at (Choosing where testsuite is run): New test

6091 * build-aux/config.guess, build-aux/config.sub,
6092 build-aux/texinfo.tex: Sync from gnulib.
6093 * doc/fdl.texi, doc/make-stds.texi, doc/standards.texi:

6098 * doc/autoconf.texi (Particular Programs): Do not mention the
6099 Autoconf version in which the AC_PROG_INSTALL change was done.
6100 Suggested by Paul Eggert.
6102 2008-01-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6104 Fix --help=recursive with multiple AC_CONFIG_SUBDIRS.
6105 * lib/autoconf/general.m4 (_AC_INIT_HELP): If, for recursive help
6106 mode, we change to the source directory, also set $ac_pwd so we
6107 do not go back to the build tree for the next config subdir.
6108 * tests/torture.at (Deep Package): Extend test to contain two
6109 config subdirs on the top level.
6111 Fix parallel `maintainer-check'.
6112 * Makefile.am (maintainer-check-tests): Depend on `all'.
6113 Use `$(MAKE) $(AM_MAKEFLAGS)' instead of plain `make'.

6163 (m4_require): Use m4_do, not m4_join.
6165 Fix some whitespace tests on cygwin.
6166 * tests/tools.at (autom4te and whitespace in file names): Restore
6167 font-lock. Create $TMPDIR before it might be used.
6169 Fix spurious testsuite failure with M4 1.4.11.
6170 * tests/local.at (AT_CHECK_M4): Cater to new m4 error message.
6172 Optimize AC_REQUIRE.
6173 * lib/m4sugar/m4sugar.m4 (m4_expansion_stack_push, _m4_defun_pro)
6174 (_m4_defun_pro_outer, _m4_defun_epi, _m4_defun_epi_outer)
6175 (m4_require): Avoid extra macro calls.
6177 2007-12-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6179 * tests/torture.at (srcdir): Fix quoting.
6181 Do not pass top_srcdir to configure scripts in testsuite.
6182 * tests/autotest.at (srcdir propagation): Copy install-sh to
6184 (my only test): Drop setting of `top_srcdir'.
6185 * tests/base.at (Input/Output): Likewise.
6186 * tests/local.at (AT_CONFIGURE_AC): Copy install-sh,
6187 config.guess, and config.sub to test source tree.
6188 Drop AC_CONFIG_AUX_DIR setting.
6189 (AT_CHECK_CONFIGURE): Drop setting of `top_srcdir'.
6190 * tests/torture.at (Substitute a 2000-byte string): Drop
6191 AC_CONFIG_AUX_DIR setting, copy install-sh to test source tree.
6192 (Substitute a newline, datarootdir workaround): Likewise.
6193 (Define a newline): Adjust for linenumber changes in configure.ac.
6194 * tests/foreign.at (Libtool): Adjust comment to reflect changes.
6196 * tests/semantics.at (AC_PATH_PROGS_FEATURE_CHECK): Skip test
6197 if `pwd` contains whitespace.
6199 Quote $abs_top_srcdir in tests.
6200 * tests/local.at (AT_CHECK_PERL_SYNTAX): Likewise.
6201 * tests/tools.at (Syntax of the shell scripts): Likewise.
6203 * tests/m4sh.at (LINENO): Quote $0.
6205 Fix testsuite program wrapper for whitespace in `pwd`.
6206 The problem here is that the usual mantra is that command
6207 variables can contain arguments, thus we cannot just escape
6208 $AUTOCONF, $AUTOM4TE etc. The compromise is to put the
6209 $top_builddir/tests directory early in $PATH, so that the
6210 wrappers are found by their plain name.
6211 * tests/wrapper.as: Put $testdir early in $PATH.
6212 (AUTOCONF, AUTOHEADER, AUTOM4TE): Set to plain command names.
6214 Proper config.status --file/--header and $srcdir escaping.

6216 characters in $ac_file_inputs.
6217 (_AC_OUTPUT_FILE, _AC_OUTPUT_HEADER): eval $ac_file_inputs
6219 * tests/torture.at (datarootdir workaround): Adjust.
6220 (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS): Extend test.
6222 Fix Autotest for whitespace in `pwd`.
6223 * lib/autotest/general.m4 (AT_INIT)
6224 <at_func_create_debugging_script, Driver Loop>:
6225 Quote $at_group_dir.
6226 * tests/autotest.at (whitespace in absolute testdir): New test.
6228 * lib/autom4te.in: Quote @datadir@.
6230 Proper file name escaping in Autoconf programs and Perl modules.
6231 This includes escaping of characters special to the shell
6232 as well as special to Perl, e.g., leading `<' or `>'.
6233 For example, when $file starts with `>', `open ">$file"'
6234 wrongly tries to append to a different file.
6235 * bin/autoconf.as: Fix quoting for autom4te options.
6236 * lib/Autom4te/General.pm (shell_quote): New function, taken
6237 from coreutils, written by Jim Meyering.
6239 * bin/autom4te.in (files_to_options, handle_m4): Use shell_quote
6241 * bin/autoreconf.in (parse_args): Likewise.
6242 * bin/autoscan.in (main): Likewise.
6243 * bin/autoupdate.in (main): Likewise.
6244 * bin/autoheader.in: Likewise, fixing old insufficient escaping.
6245 * bin/ifnames.in: Likewise, XFile usage fixes.
6246 * tests/tools.at (autom4te and whitespace in file names): Extend
6247 test. Test twice, with special characters allowed on w32, and the
6248 rest. Test leading and trailing whitespace, for `open_quote'.
6249 (autotools and whitespace in file names): New, analogous test.
6250 Reported by Paul Eggert and Benoit Sigoure, additional suggestions
6251 by Russ Allbery and Eric Blake.
6254 * lib/Autom4te/Channels.pm, lib/Autom4te/Configure_ac.pm,
6255 lib/Autom4te/Struct.pm, lib/Autom4te/XFile.pm: Likewise.
6256 * lib/Autom4te/FileUtils.pm (open_quote): New function.
6257 (update_file, contents): Use it.
6259 * Makefile.am (autom4te-update): Rewrite for git.
6261 2007-12-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6263 * doc/autoconf.texi (autom4te Invocation, Autom4te Cache): Fix typos.
6265 Fix copyright years.
6266 * Makefile.am, doc/install.texi, lib/autoconf/fortran.m4,
6267 lib/autoconf/lang.m4, lib/freeze.mk: Likewise.
6269 2007-12-04 Eric Blake <ebb9@byu.net>
6271 Manually resync with gnulib, since 'make cvs-update' no longer works.
6272 * build-aux/config.guess: New upstream version.
6273 * build-aux/config.sub: Likewise.
6275 When using older automake, don't downgrade build-aux/texinfo.tex.
6276 * configure.ac (AM_INIT_AUTOMAKE): Add no-texinfo.tex option.
6277 * doc/Makefile.am (TEXINFO_TEX): Add.
6279 2007-11-27 Paul Eggert <eggert@cs.ucla.edu>
6281 Fix AC_C_BIGENDIAN bug caused by new awk method of substitution.
6282 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Don't comment out the
6283 #undef as this runs afoul of our new way of creating config.h.
6284 Problem reported by Jim Meyering in
6285 <http://lists.gnu.org/archive/html/autoconf-patches/2007-11/msg00164.html>.
6287 2007-11-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6289 Fix autom4te for unusual characters in input file names.
6290 * bin/autom4te.in (files_to_options): Quote active characters
6292 * tests/tools.at (autom4te and white space in file names):
6295 * doc/autoconf.texi (Limitations of Usual Tools) <awk>:
6296 Document that Tru64 awk always splits $0.
6298 2007-11-24 Stepan Kasal <kasal@ucw.cz>
6300 * lib/autotest/general.m4 (AT_INIT): Do not extract the
6301 `#AT_STOP_...' line at the end of each test.
6303 2007-11-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6305 * lib/autotest/general.m4 (AT_INIT): For awk line number
6306 extraction script, ensure `$at_group' has a defined value
6307 even for the empty set, and properly quote its usage inside
6310 2007-11-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6312 * doc/autoconf.texi (Shell Functions): New chapter. Document
6313 IRIX sh $0 issue in functions, move content from ...
6314 (Portable Shell): ... here.
6315 (Shell Script Compiler): Note that shell functions are not
6316 totally unportable any more.
6318 2007-11-22 Stepan Kasal <kasal@ucw.cz>
6319 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6321 * lib/autotest/general.m4 (AT_INIT): Exit awk script after
6322 extracting the line numbers of the last needed test.
6324 2007-11-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6326 * lib/autotest/general.m4 (AT_INIT) <at_func_create_debugging_script>:
6329 2007-11-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6331 Fix IRIX testsuite debugging failures: $0 in functions.
6332 * lib/autotest/general.m4 (AT_INIT) <at_func_create_debugging_script>:
6333 Do not use $0 inside a function, as IRIX sh will set that to the
6334 function name rather than the script invocation name.
6336 2007-11-19 Paolo Bonzini <bonzini@gnu.org>
6337 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6339 * lib/autotest/general.m4 (at_func_test): Use cached line numbers
6340 to extract test scripts.
6341 (AT_INIT): Extract and cache test script line numbers.
6343 2007-11-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6345 * lib/autotest/general.m4: Revert 2007-11-15 patch and
6346 subsequent fixups; the awk -> here-document conversion trashes
6347 performance too much with AIX sh.
6349 2007-11-18 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6351 * tests/local.at: Do not test m4, perl with AT_TESTED.
6353 Diagnose and guard against write errors dealing with config.status.
6354 The general idea is this: all write failures from `configure'
6355 writing `config.status' are indicated by $ac_write_error, which
6356 is only checked at the end. This is safe because config.status
6357 code is not executed before the file is complete. Other write
6358 failures, be they inside config.status, or in sub shell/awk
6359 scripts spawned from configure or config.status, typically need
6360 earlier checking, as their results are used right afterwards.
6361 * lib/autoconf/status.m4 (AC_OUTPUT): Initialize `ac_write_fail'
6362 before writing config.status, check afterwards.
6363 (_AC_OUTPUT_FILES_PREPARE, _AC_OUTPUT_FILE)
6364 (_AC_OUTPUT_HEADERS_PREPARE,_AC_OUTPUT_CONFIG_STATUS):
6365 Set `ac_write_error' for write failures to config.status. Barf
6366 upon write failures to temporary files.
6367 Adjust note about closing and reopening the here-document.
6368 (_AC_OUTPUT_HEADER, _AC_OUTPUT_LINK, _AC_OUTPUT_COMMAND)
6369 (_AC_OUTPUT_MAIN_LOOP): Likewise, adjust note about closing and
6370 reopening the here-document.
6371 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
6372 Ensure `ac_write_error' does not escape into config.status.
6373 Also, add a couple of code paths not yet exercised in the test
6374 suite: a config file with input from stdin, and a config header
6376 Suggestion for catching write errors by Bruno Haible.
6378 2007-11-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6380 Avoid error with Tru64 awk and testsuite lines with many words.
6381 * lib/autotest/general.m4 (AT_INIT): In the awk script that
6382 reads the testsuite, set the field separator to an unusual value,
6383 in order to not run over the limit of 199 fields. Tru64 4.0D awk
6384 even splits the input if $i, i>0, was never accessed in the script.
6386 Revert 2007-10-17 change.
6387 * TODO: Multiline args in config files and headers mean something
6388 different and are not fixed, see

6394 2007-11-16 Stepan Kasal <kasal@ucw.cz>
6396 AC_*_TOOL does not canonicalize the prefix
6397 * doc/autoconf.texi (Generic Programs): Do not say that
6398 the *_TOOL macros canonicalize, they simply use the `host_alias'.
6400 2007-11-16 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6402 Diagnose write errors in config.status instantiations.
6403 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE)

6462 * lib/autoconf/types.m4 (_AC_TYPE_LONG_LONG_SNIPPET):
6463 Do not check for preprocessor flaws.
6465 2007-11-13 Jim Meyering <meyering@redhat.com>
6467 Adapt dependencies, now that a version change doesn't modify configure.ac
6468 * GNUmakefile: Remove "make clean" kludge.

6479 2007-11-12 Paul Eggert <eggert@cs.ucla.edu>
6481 * doc/autoconf.texi (Limitations of Builtins): Document problem
6482 with { ... } a bit more clearly. Suggest ":;{" as a shorthand
6484 * lib/m4sugar/Makefile.am (version.m4): Detect 'echo' failure.
6485 Use ":;{" shorthand.
6486 * tests/Makefile.am ($(srcdir)/package.m4): Likewise.
6488 2007-11-12 Jim Meyering <meyering@redhat.com>
6490 Add more non-srcdir build support.
6491 * GNUmakefile (dummy): Split a long line.
6492 Add -v option to autoreconf invocation.
6494 Remove the autoreconf-provided INSTALL, so that we regenerate it.
6495 * GNUmakefile (dummy): Remove INSTALL.
6497 Remove racy commands to build scripts in bin/ and tests/.
6498 * man/Makefile.am (.x.1): Now that scripts in bin/ and tests/
6499 are guaranteed to be built, remove the rules that tried to build
6500 them. Before, with a parallel build, these rules could lead to
6501 two processes writing tests/wrapper.in concurrently.
6503 Build in man/ only *after* building in bin/ and tests/.
6504 * Makefile.am (SUBDIRS): The man-page-creation process runs $(MAKE)
6505 in both bin/ and tests/.
6507 Accommodate non-srcdir build-from-checkout.
6508 * build-aux/git-version-gen: Require an additional parameter: $srcdir.
6509 Use git's --git-dir=$srcdir/.git option.
6510 Add quotes, in case tarball_version_file contains shell meta-characters.
6511 * GNUmakefile (_curr-ver): Pass $(srcdir) to git-version-gen.
6512 * configure.ac: Pass "." to git-version-gen.
6514 Avoid spurious test failures due to version skew.
6515 * GNUmakefile (dummy): Run $(MAKE) clean after autoreconf -i.
6517 2007-11-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6519 Avoid warnings about conftest.dSYM directories on Mac OS X Leopard.
6520 * lib/autoconf/general.m4 (_AC_LINK_IFELSE, _AC_RUN_IFELSE):
6521 Remove conftest.dSYM directory.
6522 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT)
6523 (_AC_LANG_PROGRAM_C_, _AC_FC_MAIN, __AC_FC_NAME_MANGLING):
6524 Remove `conftest.*' recursively.
6525 * lib/autoconf/lang.m4 (AC_LINK_IFELSE): Likewise.
6526 * lib/autoconf/specific.m4 (_AC_SYS_LARGEFILE_MACRO_VALUE):
6528 (_AC_COMPILER_OBJEXT_REJECT): Reject *.dSYM.
6530 Report and analysis by Jeff Squyres and Peter O'Gorman.
6532 2007-11-12 Benoit Sigoure <tsuna@lrde.epita.fr>
6534 Fix typos in variable names.
6535 * tests/semantics.at (test for AC_CHECK_LIB): s/at_m/ac_m/.
6537 2007-11-11 Benoit Sigoure <tsuna@lrde.epita.fr>
6539 Document that $((expression)) is not portable.
6540 * doc/autoconf.texi (Shell Substitutions): Here.
6542 2007-11-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6544 Ignore configure --help* errors due to LINENO-impaired shells.
6545 * tests/torture.at (Configuring subdirectories, Deep Package):
6546 In the --help* tests in read-only trees, make `.' temporarily
6547 writable again for the `stderr' file, and ignore errors due to
6548 the attempt to write configure.lineno.
6549 Report by Patrick Welche.
6551 2007-11-10 Jim Meyering <meyering@redhat.com>
6553 Generate package.m4 in build-dir, not srcdir.
6554 * tests/Makefile.am (package.m4): Adjust target.
6555 Don't redirect directly to $@.
6556 (CLEANFILES): Add package.m4.
6557 ($(TESTSUITE)): Depend on just-built package.m4, not the one
6559 When running $(AUTOTEST), search "." before searching $(srcdir).
6561 Avoid a race condition that would make parallel "distclean" fail.
6562 * tests/Makefile.am (distclean-generic): Replace the default,
6563 automake-provided rule with an identical one, but with an additional
6564 dependency on distclean-local. Simply adding the dependency would
6565 cause automake not to emit the rule at all.
6566 * BUGS: Building with -jN works, now.
6568 Distribute git-version-gen.
6569 * Makefile.am (EXTRA_DIST): Add build-aux/git-version-gen,
6570 since GNUmakefile is distributed, and requires it for dist* rules.
6572 Remove two more generated files from version control.
6573 * INSTALL: Remove generated file.
6574 * lib/autoscan/autoscan.list: Remove generated file.
6576 2007-11-09 Paul Eggert <eggert@cs.ucla.edu>
6578 * GNUmakefile (PATH): Remove stray apostrophes; they become
6579 part of PATH, which isn't wanted here.
6581 2007-11-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6583 New config files output variable `top_build_prefix'.
6584 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Substitute
6586 * doc/autoconf.texi (Preset Output Variables): Document it.
6588 Report by Bob Friesenhahn.
6590 Avoid expr for arithmetic evaluation if the shell accepts $((...)).
6591 * lib/autotest/general.m4 (AT_INIT) <at_func_arith>: New
6592 function, to parametrize arithmetic with expr vs. the shell.
6593 Use it where possible.
6594 Suggestion by Benoit Sigoure.
6596 2007-11-03 Benoit Sigoure <tsuna@lrde.epita.fr>
6598 Adjust the documentation of autotest WRT atlocal.
6599 * doc/autoconf.texi (Making testsuite Scripts): It is not necessary,
6600 when using Automake, to write a rule to produce atlocal, since it's
6601 an AC_CONFIG_FILES. Mention that atlocal.in needs to be
6602 distributed, not atconfig.in.
6604 2007-11-04 Eric Blake <ebb9@byu.net>
6606 Update list information.
6607 * README: Mention new autoconf-commit list.
6608 * doc/autoconf.texi (Introduction): Mention autoconf-commit list.
6610 2007-11-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6612 * lib/autoconf/functions.m4 (_AC_FUNC_MALLOC_IF): Fix comment typo.
6614 * lib/m4sugar/Makefile.am (version.m4): Another bash bug workaround.
6616 * build-aux/.gitignore: Ignore mkinstalldirs.
6618 * doc/autoconf.texi (autoreconf Invocation): Fix an underfull line.
6620 2007-11-03 Jim Meyering <meyering@redhat.com>
6622 s/-/./ in snapshot version string: 2.61a-256-8b556 -> 2.61a.256-8b556
6623 * build-aux/git-version-gen: This syncs from coreutils.
6625 Adjust the build procedure so "make check" works reliably.
6626 * README-hacking: Include an extra step between "make" and
6627 "make check" to ensure that the latter passes.
6629 Use just-built tools, when possible.
6630 * GNUmakefile (PATH): Set and export here, ...
6631 (dummy): ... rather than here.
6633 2007-11-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6634 and Andreas Schwab <schwab@suse.de>
6636 * tests/Makefile.am ($(srcdir)/package.m4): Work around bash
6639 2007-11-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6641 * configure.ac (AC_PREREQ): Require version 2.60, for
6642 AC_PROG_SED, AC_PROG_GREP.
6644 2007-11-02 Benoit Sigoure <tsuna@lrde.epita.fr>
6645 and Jim Meyering <meyering@redhat.com>
6646 and Andreas Schwab <schwab@suse.de>
6647 and Eric Blake <ebb9@byu.net>
6649 Document a bug in GNU Bash with compound commands and redirections.
6650 * doc/autoconf.texi (Limitations of Builtins): Mention that GNU
6651 Bash doesn't properly set $? when `{ ... } >/bad' fails, and give
6654 2007-11-03 Eric Blake <ebb9@byu.net>
6656 Support m4 1.4.5 in testsuite.
6657 * tests/torture.at (Define a newline): Exclude line numbers in
6659 Reported by Ralf Wildenhues.
6661 2007-11-03 Jim Meyering <meyering@redhat.com>
6663 Remove automake-provided files from version control.
6664 * build-aux/elisp-comp: Remove file.
6665 * build-aux/install-sh: Remove file.
6666 * build-aux/missing: Remove file.
6667 * build-aux/mdate-sh: Remove file.
6668 * build-aux/.gitignore: New file.
6669 Suggestion from Ralf Wildenhues.
6671 2007-11-03 Eric Blake <ebb9@byu.net>
6673 Adjust version comparison to account for git snapshot numbers.
6674 * lib/m4sugar/m4sugar.m4 (_m4_version_unletter): Also treat - as a
6675 component separator.

6677 <m4_version_compare>: Document this change.
6678 * tests/m4sugar.at (m4@&t@_version_compare): Test it.
6680 2007-10-30 Bruno Haible <bruno@clisp.org>
6682 * lib/autoconf/types.m4 (_AC_TYPE_LONG_LONG_SNIPPET): New macro,
6683 extracted from AC_TYPE_LONG_LONG_INT and AC_TYPE_UNSIGNED_LONG_LONG_INT.
6684 (AC_TYPE_LONG_LONG_INT, AC_TYPE_UNSIGNED_LONG_LONG_INT): Use it.
6685 Fixes problem with Sun C 5.[0-8] in 32-bit mode, reported in
6686 <http://lists.gnu.org/archive/html/autoconf-patches/2007-10/msg00210.html>
6687 Suggested by Paul Eggert.
6689 2007-10-28 Jim Meyering <meyering@redhat.com>
6691 * README-hacking: Autoconf, Automake, and Perl are required to build.
6692 List Gzip and Tar separately. Suggested by Ralf Wildenhues.
6694 2007-10-28 Jim Meyering <meyering@redhat.com>
6696 README-hacking: Recommend running autoreconf -vi.
6697 * GNUmakefile (dummy): Use autoreconf -i, with appropriate PATH,
6698 so that we use just-built tools when they're available.
6699 Suggestions from Ralf Wildenhues.
6701 2007-10-28 Jim Meyering <meyering@redhat.com>
6703 Make inter-release --version output more useful.
6705 Now, each unofficial build has a version "number" like 2.61a-19-58dd,
6706 which indicates that it is built using the 19th change set
6707 (in _some_ repository) following the "v2.61a" tag, and that 58dd
6708 is a prefix of the commit SHA1.
6709 * build-aux/git-version-gen: New file.
6710 * configure.ac: Run it to set the version.
6711 (AM_INIT_AUTOMAKE): Don't check NEWS here.
6712 * Makefile.am (dist-hook): Arrange so that .version appears only
6713 in distribution tarballs, never in a checked-out repository.
6714 * .gitignore: Add .version here, too. Just in case.
6715 * tests/Makefile.am ($(srcdir)/package.m4): Depend on Makefile,
6716 not configure.ac, now that the version number changes automatically.
6718 Ensure that $(VERSION) is up to date for dist-related targets.
6719 * GNUmakefile: Arrange to rerun autoconf, if the version reported by
6720 git-version-gen doesn't match $(VERSION), but only for dist targets.
6722 2007-10-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6724 Fix `Deep Package' failure with a configure script early in PATH
6725 * tests/torture.at (Deep Package): Add `.' early in PATH.

6733 * Makefile.in: Remove, along with all other Makefile.in in subdirs.
6734 * .gitignore: Add aclocal.m4, configure and Makefile.in. Sort.
6735 * README-hacking: New file: how to build from just-checked-out sources.
6737 2007-10-23 Eric Blake <ebb9@byu.net>
6739 Improve corner case of m4_expand.
6740 * lib/m4sugar/m4sugar.m4 (m4_expand, _m4_expand): Rewrite more

6743 * doc/autoconf.texi (Evaluation Macros) <m4_expand>: Update
6746 2007-10-23 Paul Eggert <eggert@cs.ucla.edu>
6748 * doc/make-stds.texi: Update from gnulib.
6750 2007-10-22 Paul Eggert <eggert@cs.ucla.edu>
6751 and Eric Blake <ebb9@byu.net>
6753 * lib/autoconf/c.m4 (AC_C_RESTRICT): Work around Sun C++ compatibility
6754 problem reported by Bruno Haible in
6755 <http://lists.gnu.org/archive/html/bug-autoconf/2007-10/msg00027.html>.
6757 2007-10-22 Eric Blake <ebb9@byu.net>
6759 * doc/autoconf.texi (Particular Types): Mention bug in HP-UX 11.00
6762 2007-10-22 Paul Eggert <eggert@cs.ucla.edu>
6764 Don't check for bug in HP-UX 11.00 cpp.
6765 * lib/autoconf/types.m4 (AC_TYPE_UNSIGNED_LONG_LONG_INT):
6766 Use -1ull rather than -1u, since that causes problems with gnulib; see
6767 <http://lists.gnu.org/archive/html/bug-gnulib/2007-10/msg00329.html>.
6769 2007-10-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

6774 (Multiline parenthetical command substitution): Fix typos in
6777 2007-10-21 Eric Blake <ebb9@byu.net>
6779 * configure: Regenerate.
6781 2007-10-21 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6783 Fix config status generation with Tru64 ksh.

6785 escaping of backslash in here-documents.
6787 Fix `Deep Package' test failure on FreeBSD.
6788 * tests/torture.at (Deep Package): Do not add `.' to $PATH
6789 unnecessarily. Do not try running `/bin/sh configure' with a
6790 configure script to be found in $PATH, if the shell does not do
6791 this resolution. Fixes test failure on FreeBSD.
6793 Fix config header generation with AIX awk.
6794 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS_PREPARE): In awk
6795 script, use helper array D_is_set, as `" 0"' does not evaluate
6796 to true for AIX awk.
6798 2007-10-21 Eric Blake <ebb9@byu.net>

6833 * lib/autotest/general.m4 (BANNERS): New named diversion.
6834 (TESTS_END): Diversion no longer used.
6835 (AT_INIT) <at_func_banner, BANNERS>: Factor all banners into a
6836 shell function, which prints only as needed, using an associative
6837 array of banner text from a special diversion.
6838 <PARSE_ARGS_END>: No longer need awk to find banners.
6839 <TESTS>: Banners are no longer processed by main driver loop, so
6840 we no longer need case statement.
6841 (AT_BANNER): Rewrite to populate new diversion.
6842 (AT_SETUP): Each test invokes its own banner. No output is needed
6843 to the TESTS diversion.
6844 * doc/autoconf.texi (Writing Testsuites): Document slight

6869 * lib/autotest/general.m4 (AT_TESTED, AT_KEYWORDS): Fix
6870 duplication bug by using new macro.
6871 (AT_INIT) <at_tested>: Restore newline separators. Invoke tested
6872 programs with stdin redirected, so programs that don't
6873 understand --version won't try to behave interactively.
6874 * tests/autotest.at (Tested programs): Catch this bug.
6875 * tests/m4sugar.at (m4@&t@_append): Test new macro.

6934 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): Avoid errors when `.'
6935 is not writable, use 'cp -p' in this case, in the hope that it
6936 will not actually be needed. Still try removing files, in case
6937 of other write errors.
6938 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): For ac_confdir,
6939 use $as_myself, not $0.
6940 (_AC_INIT_HELP): For --help=recursive, if the subdir does not
6941 exist, try again in the the source tree. This change assumes
6942 that the subpackage configure script is capable of running
6943 --help=recursive in the source tree.
6944 * tests/torture.at (Configuring subdirectories, Deep Package):
6945 Adjust tests to expose both issues, also try invocation as

6966 (m4_echo, m4_make_list): New documented macros.
6967 (_m4_quote, _m4_shift2): New helper macros.

7962 2007-04-30 Paul Eggert <eggert@cs.ucla.edu>
7964 * lib/m4sugar/m4sh.m4 (_AS_SHELL_FN_SPY): Don't imply that
7965 'configure' will fail if the shell lacks proper support for shell
7966 functions. Suggested by RMS.
7968 2007-04-29 Paul Eggert <eggert@cs.ucla.edu>
7970 * doc/autoconf.texi (Limitations of Builtins): Correct the warning
7971 about Solaris /bin/printf '%010000x' 123. Problem reported by
7974 2007-04-28 Paul Eggert <eggert@cs.ucla.edu>
7976 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't look
7977 for a.* when searching for executables, as this prevents users
7978 from having files like a.c. Problem reported by Ralf Wildenhues in:
7979 http://lists.gnu.org/archive/html/autoconf-patches/2007-04/msg00029.html
7980 This fixes a problem introduced on 2000-12-19.
7982 2007-04-26 Paul Eggert <eggert@cs.ucla.edu>
7984 * doc/autoconf.texi (Limitations of Builtins): Warn about Solaris
7985 /bin/printf '%010000x' 123. Problem reported by Arto C. Nirkko
7988 2007-04-12 Paul Eggert <eggert@cs.ucla.edu>
7990 * NEWS: Document recent changes to AC_CHECK_ALIGNOF, AC_CHECK_SIZEOF,
7991 AC_CHECK_TYPE, AC_CHECK_TYPES.
7992 * doc/autoconf.texi (Generic types): C types must be type-names
7993 (the C terminology), not type-ids (the C++ term). C++ types
7994 must not be anonymous.
7995 * lib/autoconf/types.m4 (_AC_CHECK_TYPE_NEW): Remove special case
7996 for C++; this drops support for anonymous struct and union types,
7997 which were problematic anyway.
7998 * tests/semantics.at (AC_CHECK_HEADERS_NEW): Adjust test to work even
8001 2007-04-12 Jim Meyering <jim@meyering.net>
8003 * doc/autoconf.texi (Libraries): Typo fix: insert missing "in".

8011 2007-04-11 Paul Eggert <eggert@cs.ucla.edu>
8013 * doc/autoconf.texi (Generic Types): Document the restrictions
8014 on types imposed by AC_CHECK_TYPE, AC_CHECK_TYPES.
8015 (Generic Compiler Characteristics): AC_CHECK_SIZEOF now works
8016 with objects too. Document the restrictions on its use.
8017 Document the restrictions on AC_CHECK_ALIGNOF's type argument.
8018 * lib/autoconf/types.m4 (_AC_CHECK_TYPE_NEW):
8019 For C, just try sizeof (TYPE) and sizeof ((TYPE)); if the former
8020 works but the latter doesn't, then it's a valid type.
8021 This lets people use function types and so forth.
8022 For C++ there doesn't seem to be a simple solution, so leave it alone.
8023 (AC_CHECK_SIZEOF): Allow argument to be a variable.
8024 (AC_CHECK_SIZEOF, AC_CHECK_ALIGNOF): Don't bother to invoke
8025 AC_CHECK_TYPE; that wasn't documented or necessary.
8027 2007-04-11 Stepan Kasal <kasal@ucw.cz>
8029 * lib/autoconf/general.m4 (_AC_LINK_IFELSE): Skip AS_TEST_X
8030 when cross-compiling.

8050 * doc/autoconf.texi (Here-Documents, Limitations of Builtins):
8051 (Limitations of Usual Tools): Don't say "older" if Solaris 10 by
8052 default still has the problem. Problem reported by Bruce Korb.

8067 command and case statements to make it a bit clearer and describe
8070 2007-03-23 Paul Eggert <eggert@cs.ucla.edu>
8072 * doc/autoconf.texi (C Compiler): Mention that AC_PROG_CC_C99 also
8073 checks for unsigned long long int.
8075 2007-03-19 Paul Eggert <eggert@cs.ucla.edu>
8077 * doc/autoconf.texi (Limitations of Usual Tools): Warn about other
8078 nonstandard grep R.E. escape sequences.
8080 2007-03-17 Jim Meyering <jim@meyering.net>
8082 * doc/autoconf.texi: Adjust grammar around use of "heuristics".
8083 (Limitations of Usual Tools): Also list \< and \>, and mention that
8084 HP-UX's grep, like the one from Solaris, does not support that syntax.
8086 2007-03-09 Stepan Kasal <kasal@ucw.cz>
8088 * doc/autoconf.texi (Specifying Names): `--host' does not
8089 change the build type.
8091 2007-03-05 Paul Eggert <eggert@cs.ucla.edu>
8093 * doc/autoconf.texi (C Compiler): Warn that AC_C_BIGENDIAN
8094 suggests AC_CONFIG_HEADERS.

8109 * NEWS: AC_C_BIGENDIAN now supports universal binaries a la Mac OS X.
8110 * doc/autoconf.texi (C Compiler): Document this. There is a new
8111 extra argument ACTION-IF-UNIVERSAL.
8112 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Implement this.
8113 Add support for Solaris-style _LITTLE_ENDIAN and _BIG_ENDIAN.
8114 Reindent for sanity's sake.
8116 2007-02-24 Eric Blake <ebb9@byu.net>

8126 * lib/autotest/general.m4 (AT_INIT): With --clean, return exit
8127 status of rm so we know when it failed.
8128 If cleaning of test dir failed before running the test, warn.
8129 Output the line separator in verbose mode before the warning
8130 to make clear the warning belongs to the following test.
8132 2007-02-08 Paul Eggert <eggert@cs.ucla.edu>

8157 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Redirect
8158 input from /dev/null in awk test, so even Solaris /usr/bin/awk

8195 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Also
8196 AC_SUBST([MKDIR_P]), so that Automake < 1.10 will pick up its
8197 trace, if a package uses AC_PROG_MKDIR_P explicitly. The actual
8198 substitution will still be done by the special code.
8199 Report by Jim Meyering.

8220 2007-01-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8222 * lib/autoconf/programs.m4 (AC_PROG_SED): When closing a pipe
8223 early on the reader side, drop stderr of the input to avoid
8224 `broken pipe' error output; this may happen even with shell
8225 builtin `echo' of some bash versions. Reports by Ian Macdonald
8226 <iamacdo@telkomsa.net> and Sam Sexton <Sam.Sexton@reuters.com>.
8228 2007-01-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

8241 http://lists.gnu.org/archive/html/autoconf-patches/2007-01/msg00077.html
8242 * doc/autoconf.texi (Signed Overflow Examples): Give more
8243 discussion about the allow_superuser_privileges example,
8244 and change it a bit to make things clearer.
8245 (Optimization and Wraparound): Clarify whether the compiler
8246 will generate an infinite loop for the example derived from
8247 Autoconf's mktime test.
8248 (Signed Overflow Advice): Say that -ftrapv is meant for debugging.
8249 Also, clarify unsigned multiplication overflow.
8251 2007-01-04 Eric Blake <ebb9@byu.net>
8253 * bin/Makefile.am (RELEASE_YEAR): New macro.
8254 (edit): Use it to supply correct copyright year to scripts.
8255 * bin/autoconf.as (version): Use it.
8256 * bin/autoheader.in ($version): Likewise.
8257 * bin/autom4te.in ($version): Likewise.
8258 * bin/autoreconf.in ($version): Likewise.
8259 * bin/autoscan.in ($version): Likewise.

8263 2007-01-02 Paul Eggert <eggert@cs.ucla.edu>
8265 * doc/autoconf.texi (Integer Overflow): Revised based on today's
8266 feedback. The most important changes document what happens when
8267 you convert an out-of-range value to a signed integer type, and
8268 say that (sum < a) != (b < 0) reliably detects overflow when sum =
8271 * doc/autoconf.texi (Integer Overflow): Greatly expand and
8272 rewrite, taking notions from the recent discussion on the gcc and
8273 autoconf mailing lists; please see
8274 http://lists.gnu.org/archive/html/autoconf-patches/2006-12/msg00091.html
8275 and follow the many links.
8276 (Integer Overflow Basics, Signed Overflow Examples):
8277 (Optimization and Wraparound, Signed Overflow Advice):
8278 (Signed Integer Division): New sections.
8280 2006-12-28 Steven G. Johnson <stevenj@alum.mit.edu>
8282 * lib/autoconf/general.m4 (AC_DEFINE_TRACE): Don't include
8283 preprocessor macro arguments in traced name.
8284 * doc/autoconf.texi (Defining symbols): Document longstanding
8285 support for AC_DEFINE-ing macros with arguments, and document
8286 behavior when the same variable has multiple AC_DEFINEs.
8287 * lib/autoconf/fortran.m4 (_AC_FC_WRAPPERS): Revert to the
8288 old implementation which AC_DEFINEs the FC_FUNC and FC_FUNC_
8289 macros directly, giving much shorter and simpler code.
8291 2006-12-28 Malcolm Purvis <malcolmp@xemacs.org> (trivial change)
8293 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Insert a
8294 space before "$ac_configure_args" to prevent a 'config.status
8295 --recheck' failure if ac_configure_args doesn't contain a leading
8296 space. This works around a problem with the XEmacs configure.ac,
8297 which uses the (undocumented) ac_configure_args variable
8298 inconsistently with Autoconf.
8300 2006-12-22 Paul Eggert <eggert@cs.ucla.edu>
8302 * lib/autoconf/functions.m4 (AC_FUNC_MKTIME):
8303 Include <limits.h>, and use its INT_MAX to rewrite the
8304 j loop so that it does not overflow 'int'. Problem reported by
8306 <http://lists.gnu.org/archive/html/bug-gnulib/2006-12/msg00084.html>.
8307 Play it safe by shifting left by 1 rather than multiplying by 2,
8308 as GCC is less likely to optimize this away when the value
8309 is signed (when it assumes overflow leads to undefined behavior).
8310 Also, don't assume time_t uses two's complement.
8312 2006-12-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8314 * tests/torture.at (Substitute a 2000-byte string): Avoid using
8315 a 10kB long (multi-line) string literal, OpenServer 5.0.7 ksh
8316 dumps core on it. Report by Tim Rice.
8318 2006-12-18 Steven G. Johnson <stevenj@alum.mit.edu>
8320 * lib/autoconf/general.m4 (AC_ARG_ENABLE): Print help about
8321 --disable-option-checking to --help output even when
8322 AC_PRESERVE_HELP_ORDER is not used.
8323 (_AC_INIT_PARSE_ENABLE2): Print warnings using actual --enable or
8324 --with argument, rather than argument with [-.] replaced by

8329 2006-12-18 Paul Eggert <eggert@cs.ucla.edu>
8331 * NEWS: Warnings are now generated by default for unknown
8332 --enable-* and --with-* options.
8333 * doc/autoconf.texi (Option Checking): Renamed from
8334 (Configure Option Checking). Tighten up the wording a bit.
8335 (External Software, Package Options): Cross-reference to Option
8336 Checking, and use this to shorten our section.
8337 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Prefer test -n
8338 "$x" to test "x$foo" != x.
8339 * lib/autoconf/status.m4 (AC_OUTPUT): Likewise.
8340 Don't warn if $enable_option_checking is "no".
8341 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Initialize
8342 ac_unrecognized_opts to the empty string.
8343 Don't echo the unrecognized opts, as this might mishandle
8344 backslashes or leading -.
8345 (AC_PRESERVE_HELP_ORDER): Put the --disable-option-checking
8346 usage next to the other --disable-FEATURE options in the
8349 2006-12-18 Steven G. Johnson <stevenj@alum.mit.edu>
8351 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS, _AC_INIT_PARSE_ARGS):
8352 (_AC_INIT_PARSE_ENABLE2, _AC_INIT_HELP, _AC_ENABLE_IF):
8353 Print warning for unrecognized --with and --enable options
8354 (AC_DISABLE_OPTION_CHECKING): New macro to disable warnings.
8355 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS, _AC_OUTPUT_SUBDIRS):
8356 Disable option checking when subdirs are configured.
8357 (AC_OUTPUT): If warnings are enabled, print warning about
8358 unrecognized --with and --enable options at the end of
8359 the configure output (as well as at the beginning).
8360 * doc/autoconf.texi (Option Checking): New node.
8361 Document new option warning functionality.
8363 2006-12-16 Eric Blake <ebb9@byu.net>
8365 * configure.ac (AC_INIT): Bump version, since 2.61a is released.
8366 * NEWS: Start news for current version.
8368 2006-12-15 Paul Eggert <eggert@cs.ucla.edu>
8370 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT):
8371 Define HAVE_GETMNTENT to 1, not to the empty string.
8372 Problem originally reported by Jochen Friedrich in
8373 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=403243>.
8375 This change prompted by a problem report by Andrey Simonenko in
8376 <http://lists.gnu.org/archive/html/bug-autoconf/2006-12/msg00026.html>.
8377 * doc/autoconf.texi (Defining Symbols): AC_DEFINE works for
8378 object-like macros only, in the traditional portable character
8380 * lib/autoconf/general.m4 (AC_DEFINE_TRACE_LITERAL):
8381 Warn about attempts to define things that are not identifiers.
8382 * lib/autoconf/fortran.m4 (_AC_FC_WRAPPERS): Rewrite to avoid
8383 awful hack that AC_DEFINEd macro names containing parentheses.
8385 2006-12-12 Paul Eggert <eggert@cs.ucla.edu>
8387 * doc/autoconf.texi: Undo some of the 2006-12-10 change. It was
8388 too drastic, even if Texinfo in theory requires it for info mode.
8390 (config.status Invocation): Renamed back from Recreating a
8392 (Obsolete config.status Use): Renamed back from Obsolete Recreation.
8393 (Autoconf 2.13): Renamed back from 20th-century Autoconf 2.
8395 2006-12-11 Paul Eggert <eggert@cs.ucla.edu>
8397 * NEWS: Version 2.61a.
8399 2006-12-11 Paul Eggert <eggert@cs.ucla.edu>
8400 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8402 * NEWS: Document changes with echo and printf, and the lack
8403 of limits on the total size of multi-line values of substituted
8404 variables, and the AC_FUNC_FSEEKO fix.
8406 2006-12-10 Paul Eggert <eggert@cs.ucla.edu>
8408 * doc/autoconf.texi (Writing Autoconf Input): Renamed from
8409 Writing configure.ac.
8410 (Autoconf Input Layout): Renamed from configure.ac Layout.
8411 (Recreating a Configuration): Renamed from config.status Invocation.

8415 (Writing Testsuites): Renamed from Writing testsuite.at.
8416 (Autom4te Cache): Renamed from autom4te.cache.
8418 * BUGS: Remove mention of VPATH problem, since it's now documented
8419 not to be a bug in the Autoconf build procedure itself, but rather
8420 a problem with the proprietary `make' programs.
8422 * doc/autoconf.texi (Build Directories): Add a cross reference
8425 * build-aux/config.guess, build-aux/config.sub, build-aux/texinfo.tex:

8435 * lib/autoconf/c.m4 (_AC_PROG_CC_C89): Also try -xc99=all, for Sun
8436 C 5.8 on Solaris 10. Using -xc99=all rather than -xc99 bypasses
8437 the buggy -xc99 option of Forte Developer 7 C on Solaris 9.
8439 2006-12-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8441 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Drop the
8442 `CEOF$ac_eof' special marker, the awk script cannot contain a
8443 line matching `^CEOF', so this is not needed any more.
8444 * tests/torture.at (Substitute a newline): Expose the `%!_!# '
8445 special marker in the test.
8447 2006-12-06 Stepan Kasal <kasal@ucw.cz>
8449 * tests/tools.at (autom4te preselections): Use `find -newer';
8450 remove one of the sleeps.
8452 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE): Make it
8453 more readable, using ...
8454 (_AC_INIT_PARSE_ENABLE2): ... this new helper macro.
8456 * doc/autoconf.texi (autoheader Invocation): Do not double-
8457 quote the parameter of `AH_BOTTOM' in the example.
8459 2006-12-05 Stepan Kasal <kasal@ucw.cz>
8461 * doc/autoconf.texi (Configuration Headers): Remove the
8462 example with multiple input files.
8463 (autoheader Invocation): Encourage `AH_BOTTOM', discouraging
8464 multiple input files.
8466 2006-12-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8468 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): When
8469 creating the awk substitution script, handle one input line at a
8470 time, so that the maximum length of a substituted (multi-line)
8471 value is not limited by the size of the sed pattern space.
8472 The trade-off is a slightly repetitive sed script.
8473 * doc/autoconf.texi (Limitations of Usual Tools): Branch labels
8474 can only have up to 7 characters, due to Solaris 10 /bin/sed.
8475 * tests/torture.at (Substitute a 2000-byte string): Increase the
8476 test with several long lines, they should not be caught by sed
8479 * tests/tools.at (autom4te preselections): New test, to flag
8480 entries missing from autom4te.cfg.
8481 Report by David Byron <dbyron@hheld.com>.
8483 * tests/torture.at (Substitute a 2000-byte string): Actually use
8484 AC_PROG_AWK, so the last change works as intended.
8485 (Substitute and define special characters): Likewise.
8486 (Substitute a newline): Likewise.
8488 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Use `$AWK'
8489 instead of `awk' consistently.
8490 (_AC_OUTPUT_CONFIG_STATUS): Initialize $AWK.
8491 * tests/torture.at (Torturing config.status): Test both the
8492 result of AC_PROG_AWK and plain awk.
8493 (Substitute a 2000-byte string): Likewise.
8494 (Substitute and define special characters): Likewise.
8495 (Substitute a newline): Likewise.
8497 2006-12-04 Paul Eggert <eggert@cs.ucla.edu>
8499 * lib/autoconf/functions.m4 (AC_FUNC_FSEEKO): Check that fseeko
8500 can be assigned to a function pointer. Problem reported by
8501 Peter Palfrader in <http://bugs.debian.org/401377>. Based on
8502 part of a patch by Ralf Wildenhues in that same bug report.
8504 2006-12-01 Paul Eggert <eggert@cs.ucla.edu>
8506 * tests/mktests.sh (ac_exclude_list): Exclude AC_FUNC_SETVBUF_REVERSED.
8507 * tests/semantics.at (AC_FUNC_SETVBUF_REVERSED): New test.
8509 2006-12-01 Eric Blake <ebb9@byu.net>
8511 * lib/autoconf/c.m4 (AC_LANG_INT_SAVE): Avoid newline, to aid in
8512 cross-compiling from cygwin to mingw.
8513 Reported by Bob Rossi. This resurrects the 2000-11-30 patch to
8514 aclang.m4, which was mistakenly removed in the 2001-09-17 patch
8515 to lib/autoconf/c.m4.
8517 2006-12-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8519 * lib/m4sugar/m4sh.m4 (_AS_ECHO_PREPARE): Use a longer test
8520 string for more reliable failure. Wrap the entire test that
8521 causes the broken Solaris printf to dump core, in a subshell,
8522 so the segmentation fault message is reliably suppressed.
8523 Fix shell expansion errors by using /usr/ucb/echo always;
8524 avoid an error on systems without it by another subshell.
8525 Avoid m4 expansion of `$1'. Set the zeroth argument of the
8526 subshell-$as_echo to `as_echo', for better error message.
8528 2006-11-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8530 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): If `BASH_ARGV' or
8531 `BASH_SOURCE' contain a newline, set them to empty, as they may
8534 2006-11-27 Paul Eggert <eggert@cs.ucla.edu>
8536 Turn AC_FUNC_SETVBUF_REVERSED into a noop. It's been obsolete for
8537 years and is too hard to maintain now. The last straw was
8538 reported by Jerker Baeck in
8539 <http://lists.gnu.org/archive/html/autoconf/2006-11/msg00102.html>.
8540 * NEWS: AC_FUNC_SETVBUF_REVERSED is now obsolete.
8541 * doc/autoconf.texi (Particular Functions): Move
8542 AC_FUNC_SETVBUF_REVERSED from here...
8543 (Obsolete Macros): ... to here. Say that it does nothing now.
8544 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
8545 Turn into (almost) a no-op.
8547 * lib/autoconf/c.m4 (AC_PROG_GCC_TRADITIONAL, AC_C_CONST):
8549 Do not recommend via AN_FUNCTION, AN_IDENTIFIER, or AN_HEADER.
8550 These macros are obsolescent and new applications shouldn't need them.
8551 * lib/autoconf/functions.m4 (AC_FUNC_CLOSEDIR_VOID, AC_REPLACE_FNMATCH):

8557 (AC_HEADER_STDC, AC_HEADER_SYS_WAIT, AC_HEADER_TIME): Likewise.
8558 * lib/autoconf/types.m4 (AC_STRUCT_TM): Likewise.
8560 * doc/autoconf.texi (Setting Output Variables): Mention that
8561 @VAR1@VAR2 has unspecified behavior. Problem reported by
8563 * NEWS: Mention this.
8565 * Makefile.am: Put only a single '#' into the copyright notice,
8566 so that it's also present in the output file. Standardize wording
8567 in makefile copyright notices to match GNU coding standards.
8568 * bin/Makefile.am: Likewise.

8581 2006-11-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8583 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Fix error
8584 in the sed script that mangles the awk script: delete up to the
8585 first exclamation mark only.
8586 * tests/torture.at (Substitute and define special characters):
8589 2006-11-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8591 Rewrite config files generation: avoid quadratic growth in
8592 the number of substituted variables by using awk instead of sed
8593 for the bulk of the substitutions.
8594 * NEWS: Mention this.
8595 * doc/autoconf.texi (Setting Output Variables): `|#_!!_#|' is also
8596 forbidden in the output (and thus input) file.
8597 * lib/autoconf/status.m4 (_AC_AWK_LITERAL_LIMIT): New macro.
8598 (_AC_OUTPUT_FILES_PREPARE): Instead of several sed scripts,
8599 generate just one large awk script for substitutions,
8600 eliminating much of the earlier complexity, while adding some
8601 new complexity. Only expand the substitution templates at
8602 configure time, for smaller configure script size. If
8603 _AC_SUBST_FILES are used, test 'awk' for working getline support
8604 at config.status time. If absent, interpolate through the
8605 shell. The awk script was written with much help
8606 from Paolo Bonzini and Paul Eggert.
8607 (_AC_SED_CMD_NUM, _AC_SED_DELIM_NUM, _AC_SED_FRAG): Removed.
8608 (_AC_SED_FRAG_NUM): Likewise.
8609 (_AC_SUBST_CMDS): Renamed from...
8610 (_AC_SED_CMDS): ...this.
8611 (_AC_OUTPUT_FILE): Use _AC_SUBST_CMDS.
8612 * tests/torture.at (Substitute a 2000-byte string): Also
8613 substitute a line with 1000 words, and a variable with several
8615 (Substitute and define special characters): Test awk special
8616 characters, and put substitution input strings `@foo@' in the
8617 output, to test that no recursion happens; test several other
8618 combinations from Paolo Bonzini.
8620 2006-11-25 Paul Eggert <eggert@cs.ucla.edu>
8622 * lib/autotest/general.m4 (AT_INIT): Undo recent changes
8623 that replaced echo with AS_ECHO where this wasn't necessary.
8624 Problem reportd by Ralf Wildenhues.
8625 * lib/m4sugar/m4sh.m4 (_AS_ECHO_PREPARE): Port to Solaris 7,
8626 where "/usr/bin/printf '%s\n' S" dumps core if S is long.
8627 This is Sun bug 4206210. Problem reportd by Ralf Wildenhues.
8629 2006-11-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8631 * lib/freeze.mk (GREP): Removed, no need to initialize this.
8633 2006-11-21 Paul Eggert <eggert@cs.ucla.edu>
8635 * doc/autoconf.texi (Limitations of Usual Tools): Don't claim
8636 that traditional Awk lacks 3-arg "split". It has it.
8637 Mention that FS must be a single character, and a few other
8638 99-byte limits of traditional Awk.
8639 Mention that if (i in a) doesn't work with traditional Awk.
8641 2006-11-18 Paul Eggert <eggert@cs.ucla.edu>
8643 * tests/autotest.at (BSx641-newline in command):
8644 (BS-BS-newline in command, BSx640-newline in command):
8645 (Newline-CODE-BS-newline in command):
8646 (Single-quote-BS-newline in command):
8647 (Single-quote-newline-BS-newline in command):
8648 Use printf '%s\n' instead of echo, for portability to hosts
8649 where echo interprets backslashes. This will break on hosts
8650 that lack printf, but for now let's assume all such hosts
8651 are dead (if not, we should get reports of test failures).
8653 2006-11-17 Paul Eggert <eggert@cs.ucla.edu>
8655 'echo' has some portability problems, when given a first argument
8656 with a leading '-', or when given any argument containing '\'.
8657 Avoid using 'echo' in these cases.
8658 * bin/Makefile.am $(bin_SCRIPTS): Rewrite to avoid 'echo' entirely.

8686 * lib/autoconf/general.m4 (AC_MSG_RESULT, AC_MSG_RESULT_UNQUOTED):
8687 Don't use ECHO_T, since ECHO_N is now reliable.
8688 * lib/autotest/general.m4 (AT_INIT): Likewise.
8689 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Use sed "$script"
8690 rather than using a here-document to put the script into a file.
8691 (_AC_DO_ECHO): Hoist the eval out of the echo, so that we can
8693 * lib/m4sugar/m4sh.m4 (AS_VAR_GET): Likewise.
8694 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Use
8695 AS_ECHO_N rather than ECHO_N and ECHO_C. This doesn't fix any
8696 bug, but we might as well stop using ECHO_N and ECHO_C internally.
8697 * lib/autotest/general.m4 (AT_SETUP): Likewise.

8699 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
8700 (_AC_OUTPUT_MAIN_LOOP): Rework echo so that it has just one
8701 operand, as AS_ECHO requires. Avoid double file name expansion.
8702 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Invoke _AS_ECHO_PREPARE.
8703 Don't set as_nl, since _AS_ECHO_PREPARE does that now.
8704 (_AS_PREPARE): Comment that _AS_ECHO_N_PREPARE is just for user code.
8705 (AS_ECHO, AS_ECHO_N, _AS_ECHO_PREPARE): New macros.
8706 * tests/c.at (AC_PROG_CPP without warnings, AC_PROG_CPP via CC):
8707 Double-quote strings that would otherwise contain M4 comments.
8708 * tests/m4sh.at (AS_ECHO and AS_ECHO_N): New test.
8710 * configure.ac (AC_INIT): Bump to 2.61a.
8713 2006-11-17 Paul Eggert <eggert@cs.ucla.edu>
8717 * configure.ac (AC_INIT): Bump to 2.61.
8720 * tests/autotest.at (Macro with backslash in a test title):
8721 Comment out for now, as this tests neither fails nor passes
8722 reliably. Problem reported by Ralf Wildenhues.
8724 2006-11-16 Paul Eggert <eggert@cs.ucla.edu>
8726 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE): Fix some typos
8727 in previous change, which caused test failures.

8732 code for --enable, --disable, --with, and --without to...
8733 (_AC_INIT_PARSE_ENABLE): ... a new macro.
8734 * doc/autoconf.texi (Package Options):

8739 Import these changes from config via gnulib:
8741 2006-11-15 Ben Elliston <bje@gnu.org>
8743 From Josselin Mouette <joss@debian.org>:

8796 first argument may also contain dots.
8798 2006-11-09 Paul Eggert <eggert@cs.ucla.edu>
8800 * tests/mktests.sh (ac_exclude_list): Exclude AC_PROG_CXX_C_O, for
8801 benefit of platforms like Solaris+GCC where it is common to have a
8802 non-working g++ installation.

8809 and non-portable sed scripts, and use $CONFIG_SHELL when invoking
8812 2006-11-08 Paul Eggert <eggert@cs.ucla.edu>
8814 * lib/autoconf/types.m4 (AC_TYPE_LONG_LONG_INT): Set
8815 ac_cv_type_long_long_int to 'yes' instead of 'cross-compiling'.
8816 Imported from a similar patch to gnulib by Bruno Haible.
8818 2006-11-08 Paul Eggert <eggert@cs.ucla.edu>
8820 * NEWS: New macros AC_C_FLEXIBLE_ARRAY_MEMBER, AC_C_VARARRAYS.
8821 * doc/autoconf.texi (C Compiler): Document them.
8822 * lib/autoconf/c.m4 (AC_C_FLEXIBLE_ARRAY_MEMBER, AC_C_VARARRAYS):
8823 New macros, taken from gnulib.
8825 2006-11-07 Paul Eggert <eggert@cs.ucla.edu>

8831 2006-10-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8833 * tests/torture.at (Configuring subdirectories): Do not skip
8834 Automake 1.10 nor future Automake 11.1 (sic).
8836 2006-10-26 Joel E. Denny <jdenny@ces.clemson.edu>
8837 and Stepan Kasal <kasal@ucw.cz>
8839 Handle special characters in test case titles correctly.
8840 * lib/autotest/general.m4 (AT_INIT): M4-quote and AS_ESCAPE AT_help_all
8842 (AT_SETUP): M4-quote and AS_ESCAPE the title properly everywhere.
8843 * tests/autotest.at (AT_CHECK_AT_TITLE): Add EXPANDED-TITLE-TO-TEST
8844 argument. Extend to check titles printed by ./micro-suite and
8845 ./micro-suite -l and the title in micro-suite.log.
8846 (Backquote in a test title,
8847 Single-quote in a test title,
8848 Double-quote in a test title): Don't expect failure anymore.
8849 (Backslash in a test title): Put a non-whitespace character after the
8850 backslash so that Bourne shells might actually see it as an escape
8852 (Brackets in a test title,
8853 Pound in a test title,
8854 Comma in a test title,
8855 Quoted Macro in a test title,

8858 (Macro with backquote in a test title,
8859 Macro with double-quote in a test title,
8860 Macro with backslash in a test title): New tests expected to fail.
8861 * tests/torture.at (#define header templates): M4-quote this title in
8862 AT_SETUP call so that no M4 code is commented inadvertently somewhere.
8863 The visible effect was a stray [] in the testsuite output.
8865 2006-10-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8867 * doc/autoconf.texi (Limitations of Builtins): Do not invoke
8868 `trap ... 0' inside a function, for AIX sh.
8870 2006-10-26 Paul Eggert <eggert@cs.ucla.edu>
8872 * tests/base.at (AC_COMPUTE_INT): Test **0** rather than 1 / 0,
8873 since powerpc-apple-darwin8-gcc-4.0.1 (Apple Computer, Inc. build
8874 5363) simply issues a warning when dividing by zero at compile
8875 time. Problem reported by Elias Pipping.
8877 2006-10-26 Eric Blake <ebb9@byu.net>
8880 * doc/autoconf.texi (Evaluation Macros): Improve the example to
8881 show effect on macros that expand with commas.

8906 2006-10-24 Paul Eggert <eggert@cs.ucla.edu>
8908 * lib/autoconf/specific.m4 (_AC_SYS_LARGEFILE_MACRO_VALUE):
8909 If FUNCTION-BODY is nonempty, use AC_LINK_IFELSE rather than
8910 AC_COMPILE_IFELSE, to work around problem with OSF/1 4.0F fseeko
8911 reported by Nelson H. F. Beebe for Coreutils 6.4.
8913 * tests/tools.at (autoconf --trace: user macros): Remove test
8914 for tracing multiline macros, since m4 1.4.7a uses a different
8915 way to number lines. Problem reported by Ralf Wildenhues.

8945 * lib/autoconf/types.m4: All uses of AC_CACHE_CHECK_INT changed.
8946 * tests/base.at (AC_COMPUTE_INT): Test this, not AC_CACHE_CHECK_INT.

8993 (Imported from Automake.)
8994 * build-aux/install-sh (posix_mkdir): Reject FreeBSD 6.1 mkdir -p -m,
8995 which incorrectly sets the mode of an existing destination
8996 directory. In some cases the unpatched install-sh could do the
8997 equivalent of "chmod 777 /" or "chmod 0 /" on a buggy FreeBSD
8998 system. We hope this is rare in practice, but it's clearly worth
8999 fixing. Problem reported by Alex Unleashed in
9000 <http://lists.gnu.org/archive/html/bug-autoconf/2006-10/msg00012.html>.
9001 Also, don't bother to check for -m bugs unless we're using -m;
9002 suggested by Stepan Kasal.

9051 added to the template can get mangled.
9053 2006-10-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9055 * lib/autoconf/functions.m4 (AC_FUNC_OBSTACK): In the test,
9056 include the default headers, and redefine obstack_chunk_alloc
9057 and obstack_chunk_free. Fixes false failure with glibc.
9059 2006-10-12 Paul Eggert <eggert@cs.ucla.edu>
9061 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Set as_executable_p,

9074 the NonStop platform.
9075 * doc/autoconf.texi (Posix Variants): Likewise.
9076 * lib/autoconf/specific.m4 (AC_USE_SYSTEM_EXTENSIONS): Likewise.
9078 * lib/m4sugar/m4sh.m4 (AS_TEST_X): New macro.
9079 (AS_EXECUTABLE_P): Use as_test_x rather than as_executable_p.
9080 (_AS_TEST_PREPARE): Set as_test_x rather than as_executable_p.
9081 Use a better substitute, by inspecting the output of "ls"
9082 rather than just using ":".
9083 * lib/autoconf/general.m4 (_AC_LINK_IFELSE): Use AS_TEST_X
9084 rather than AS_EXECUTABLE_P, since we needn't worry about
9085 non-regular files here.
9087 * NEWS: Autoconf-generated shell scripts no longer export BIN_SH,
9088 due to configuration hassles with this. See Tonya Underwood's report
9089 <http://lists.gnu.org/archive/html/bug-autoconf/2006-10/msg00003.html>.

9101 initialization which is not inherited through the environment
9102 (_AS_BOURNE_COMPATIBLE): ... to this new macro.
9103 (_AS_RUN): Call _AS_BOURNE_COMPATIBLE, not AS_BOURNE_COMPATIBLE.

9108 problems with mkdir -p -m.
9110 2006-10-06 Paul Eggert <eggert@cs.ucla.edu>
9112 * lib/autoconf/c.m4 (_AC_PROG_PREPROC_WORKS_IFELSE): Remove
9113 comment about ac_cpp_err; it was incorrect, and anyway
9114 ac_cpp_err is being removed below.
9115 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE): Don't
9116 set ac_cpp_err to 'yesyes' if preproc_warn_flag and werror_flag
9117 are both 'yes'. In fact, don't bother setting ac_cpp_err at all;
9119 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't log our funky tests
9120 with werror_flag and conftest.err and so forth. This is more
9121 compatible with how _AC_PROG_PREPROC_WORKS_IFELSE behaves,
9122 and anyway the user shouldn't normally want to see this gorp logged.
9123 Problem reported by Ralf Wildenhues.
9124 * lib/autoconf/lang.m4 (AC_LANG_WERROR): werror_flag's default is
9125 empty, not 'no', since the rest of the code uses 'test -z'.
9127 2006-10-04 Paul Eggert <eggert@cs.ucla.edu>
9129 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE):
9130 Use a single call to AC_DO_TOKENS rather than multiple, for
9132 (_AC_LINK_IFELSE): Test that resulting file is executable.
9133 Problem reported by mwoehlke in
9134 <http://lists.gnu.org/archive/html/bug-coreutils/2006-10/msg00048.html>.
9136 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Use "test -x /" rather
9137 than creating a file to use with test -x; this is much faster.
9139 2006-10-02 Bruno Haible <bruno@clisp.org>
9141 * lib/autom4te.in (Automake-preselections): Add
9142 AM_GNU_GETTEXT_INTL_SUBDIR, for automake 1.10.
9144 2006-09-27 Stepan Kasal <kasal@ucw.cz>
9146 * doc/autoconf.texi (Writing testsuite.at): Fix a typo: for
9147 standard error, `experr' should be used, not `expout'.

9151 * lib/autoconf/functions.m4 (AC_FUNC_FSEEKO): Don't compile the
9152 fseeko testing program twice; just use the earlier result.
9153 * lib/autoconf/specific.m4 (_AC_SYS_LARGEFILE_MACRO_VALUE):
9154 Set cache var to 'unknown' (not 'no') if leaving the macro unset
9155 still doesn't let the program compile.
9156 (AC_SYS_LARGEFILE): Test for _LARGE_FILES only if earlier tests
9159 * lib/autoconf/functions.m4: Fix problems reported by Ralf Wildenhues.
9160 (AC_FUNC_ERROR_AT_LINE): Don't bother to check for error.h. Just
9161 include it, without including anything else.
9162 (AC_FUNC_FSEEKO): Avoid gcc -Wall warnings about constant
9164 (AC_FUNC_STRNLEN): Require AC_USE_SYSTEM_EXTENSIONS.

9169 `error.h', and include it, for a `error_at_line' prototype.
9170 Use a nonempty format string in the link test.
9171 * lib/autoconf/functions.m4 (AC_FUNC_WAIT3): Include <sys/wait.h>,
9172 for a declaration of wait3.

9178 can apply to constants too, and that it checks for macro defns.
9179 * lib/autoconf/general.m4 (AC_CHECK_DECL): Assume C89 or better,

9181 values. Problem reported by Ralf Wildenhues.

9396 broken lex libraries like native ia64-hp-hpux11.22; see
9397 <http://sources.redhat.com/ml/binutils/2003-12/msg00337.html>, and

9526 rather than "#if HAVE_STDLIB_H", so that it now works with "gcc
9527 -Wundef -Werror". Problem reported by David Fang in
9528 <http://lists.gnu.org/archive/html/autoconf/2006-08/msg00045.html>.

9550 * doc/autoconf.texi (Limitations of Usual Tools): Document sed
9551 problems with arg script text that doesn't end in newline, and

9603 2006-07-17 Paul Eggert <eggert@cs.ucla.edu>
9605 * lib/autoconf/libs.m4 (AC_PATH_XTRA): Do the check for space
9606 after -R regardless of host. Patrick Welche reports that this

9617 * doc/autoconf.texi (C Compiler): Add a ref to Volatile Objects
9618 under AC_C_VOLATILE.
9619 (Volatile Objects): Be a little less skeptical about what
9620 "volatile" means. Derived from thoughts by Ben Pfaff in
9621 <http://lists.gnu.org/archive/html/bug-gnulib/2006-07/msg00092.html>.

9629 * tests/torture.at (Configuring subdirectories): Set CONFIG_SITE
9630 more globally, since the 2006-06-30 patch didn't suffice. Problem
9631 reported by Keith Marshall. Also, don't bother with builddir2,
9632 since it shouldn't be needed any more.
9634 2006-07-07 Paolo Bonzini <bonzini@gnu.org>
9636 * doc/autoconf.texi (Generic compiler characteristics):
9637 Document AC_COMPUTE_INT. Fix wrong statements on Default

9653 2006-07-02 Paul Eggert <eggert@cs.ucla.edu>
9655 * lib/autoconf/types.m4 (AC_TYPE_LONG_LONG_INT):
9656 Require that long long int be at least 64 bits wide. C99 requires
9657 this and enough programs depend on it so we should check for it.
9658 Bruno Haible reports in
9659 <http://lists.gnu.org/archive/html/bug-gnulib/2006-06/msg00286.html>
9660 that long long int is 32 bits wide with some nonstandard compilers.

9665 * tests/torture.at (Configuring subdirectories): Set CONFIG_SITE
9666 to a nonexistent file, so that we don't have to worry about
9667 a local site configuration that doesn't use /usr/local.
9668 Problem reported by Keith Marshall in
9669 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00133.html>.
9671 2006-06-28 Paul Eggert <eggert@cs.ucla.edu>
9673 * doc/autoconf.texi: Be more consistent about using @acronym with
9674 "HP" and "HP-UX". Remove mention of OSF; the old version wasn't
9675 quite right (it talked about "OSF/Tru64", even though the
9676 operating systems were called OSF/1, Digital UNIX, and Tru64 UNIX,
9677 and it even mentioned "OSF 4"!) and at this point there's little
9678 reason to talk about OSF any more, since it died in 1994.
9679 (Specific Compiler Characteristics): Simplify example of
9680 negative-size array.
9681 (File Descriptors): Reorder to make the text flow better.
9682 Remove joke about "appreciate the various levels"; I didn't get it.
9683 Add remark about HP-UX sh -x bug with stderr noted by Bob Proulx in
9684 <http://lists.gnu.org/archive/html/bug-coreutils/2006-06/msg00225.html>.
9685 (File Descriptors, Limitations of Usual Tools):
9686 Tone down the advice against renaming or removing open files.
9687 (Limitations of Usual Tools): Add a new section, on 'rm'.
9689 2006-06-26 Stepan Kasal <kasal@ucw.cz>
9691 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Use -lX11, not
9692 -lXt in LIBS, idea from Karsten Hopp; this was due since
9695 2005-09-18 Paul Eggert <eggert@cs.ucla.edu>
9696 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Look for X11/Xlib.h
9697 and XrmInitialize rather than X11/Intrinsic.h and XtMalloc
9698 (which belong to Xt, not X itself). See Debian bug 327655.
9700 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9702 * configure.ac (AC_INIT): Bump to 2.60a.

9722 datarootdir-related errors only if AC_DATAROOTDIR_CHECKED is
9724 * doc/autoconf.texi (Changed Directory Variables): New node,
9725 to document the whole `datarootdir' business a bit better.
9727 * tests/torture.at (datarootdir workaround): Extend test.
9728 Prompted by report by Alexandre Julliard.
9730 2006-06-22 Paul Eggert <eggert@cs.ucla.edu>
9732 * lib/autoconf/c.m4 (_AC_PROG_CC_C89): Check for C89 incompatibility
9733 when using default mode of IBM C 6 for AIX. Problem and two-line
9734 fix reported by Larry Jones.
9736 2006-06-22 Alexandre Julliard <julliard@winehq.org>
9738 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Avoid warning
9739 about literal '${datarootdir}' if a definition is found in the
9742 2006-06-20 Paul Eggert <eggert@cs.ucla.edu>
9744 * NEWS: Use "M4" rather than "m4" when appropriate.
9745 Problem reported by Eric Blake.
9746 * doc/autoconf.texi: Likewise.
9747 Use @acronym around BSD, GCC, and GNU when appropriate.
9748 (Why GNU M4): Renamed from "Why GNU m4".
9749 (Redefined M4 Macros): Mention that Posix
9750 m4wrap takes only 1 argument, but GNU M4 1.4.x takes more.
9751 (Buffer Overruns): Mention size_t and ptrdiff_t as alternatives
9754 2006-06-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9756 * bin/autom4te.in (handle_output): Do not forbid the empty
9758 * tests/tools.at (autoconf: the empty token): New test.
9760 2006-06-20 Stepan Kasal <kasal@ucw.cz>
9762 * lib/m4sugar/m4sugar.m4 (m4_init): Merge the two m4_wrap
9763 calls, so that we do not care whether they are LIFO or FIFO;
9764 in the m4_wrap, do not check which diversion is the topmost
9765 one, just check that the stack is balanced at the end.
9766 * lib/m4sugar/m4sh.m4 (AS_INIT): We are going to change the
9767 base diversion forever--pop the previous diversion before
9768 opening the new one; consequently, remove the m4_wrap call.
9769 * lib/autotest/general.m4 (AT_INIT): Likewise.
9770 * tests/m4sugar.at: Do not use
9771 m4_wrap([m4_diversion_pop([..])]), for educational purposes.

9774 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9776 * NEWS: Document that m4wrap/m4_wrap might not be LIFO.
9777 * doc/autoconf.texi (Redefined M4 Macros): Likewise.
9778 Rework example of m4wrap token-pasting trouble so that it doesn't
9779 care whether it's LIFO or FIFO.
9780 Fix some "contrary to"s that are awkward in English.
9782 2006-06-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9784 * lib/autoconf/types.m4 (_AC_TYPE_INT): Set `$ac_cv_c_int$1_t'
9785 to `yes' instead of `int$1_t' if the type is found, for more
9786 consistent configure output (where $1 is the number of bits).
9787 (_AC_TYPE_UINT): Likewise for `uint$1_t'.
9788 Suggested by Bruno Haible.
9790 * lib/autoconf/types.m4 (_AC_TYPE_UNSIGNED_INT): Solaris 2.5.1
9791 needs _UINT8_T and _UINT64_T defines as well, to avoid clashes
9792 with system headers. Report by Bruno Haible.
9794 2006-06-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9796 * config/config.guess, config/config.sub: Sync from upstream.
9798 * bin/Makefile.am (autoconf.in): Use `--melt' for autom4te,
9799 in order to avoid picking up an older installed frozen m4sh.m4f.
9800 Besides an outdated shell startup, this could have been created
9801 by an earlier M4 version with incompatible frozen file format.
9803 2006-06-16 Paul Eggert <eggert@cs.ucla.edu>
9805 * README: Recommend m4 1.4.4 instead of 1.4.3..
9806 * doc/autoconf.texi: Likewise.

9808 suggested by Stepan Kasal.
9809 (Installation Directory Variables, Build Directories):
9810 (Automatic Remaking, Subdirectories, Fortran Compiler):
9811 (Making testsuite Scripts, Defining Directories):
9812 Quote variable usages better.
9813 (Making testsuite Scripts): Add clean-local rule to makefile
9814 snippet, by Eric Blake.
9815 (Installation Directory Variables): Fix table item font.
9816 Reword slightly to clarify. Generalize advice about
9817 not using special characters to include all file-related
9818 vars, not just VPATH.
9819 (Special Chars in Variables): Warn about special characters in
9821 (Assignments): Clarify default-value example as suggested by
9823 <http://lists.gnu.org/archive/html/autoconf-patches/2006-06/msg00072.html>.
9824 (Special Shell Variables): Note leading ./ or ../, as suggested
9826 (Limitations of Builtins): Under cd, warn about CDPATH.
9827 (The Make Macro MAKEFLAGS): Untabify. Problem reported by
9830 2006-06-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9832 * doc/autoconf.texi (Configuration Actions): Remove duplicate
9833 `@var', for texi2html.
9834 (Systemology): Some more word wrapping, for DVI output.
9835 (autom4te Invocation): The short option for `--melt' is `-M',
9838 2006-06-15 Paul Eggert <eggert@cs.ucla.edu>
9840 * doc/autoconf.texi: More formatting and English tweaks,
9841 many suggested by Ralf Wildenhues.
9842 Reword to avoid "@code{...}'s" and the like, since it's ugly
9843 with Emacs info mode. discontents -> woes.
9844 Put a few "will"s back. time stamp -> timestamp.
9845 side-effect -> side effect.
9847 2006-06-14 Paul Eggert <eggert@cs.ucla.edu>
9849 * doc/autoconf.texi (Initializing configure, Shell Substitutions):
9850 Warn about $@ not persisting. Problem reported by Julien Danjou in
9851 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=372179>.
9852 (Special Chars in Names): Renamed from Leading _ in Macro Names.
9853 Mention other special chars, too.
9855 2006-06-14 Eric Blake <ebb9@byu.net>
9857 * doc/autoconf.texi (The Make Macro MAKEFLAGS): New node.
9859 2006-06-13 Paul Eggert <eggert@cs.ucla.edu>
9861 * doc/autoconf.texi: Some systematic minor improvements, as
9862 follows. Use "makefile" when talking about makefiles
9863 generally (which might be named "makefile" or "Makefile" or even
9864 "foo.mk"), "Makefile" when talking about a specific makefile
9865 called "Makefile". This unclutters the text from weird quotes
9866 (e.g., "`Makefile's" in info mode). Similarly, use "@var{foo}
9867 values" rather than "@var{foo}s" and similar constructs containing
9868 "}s". Use "Make rules" rather than "Makefile rules". Minor
9869 English-language improvements. Change the prefix "sub-" to "sub"
9871 Put blank lines around examples more consistently.
9872 Avoid "rather" and "very" as intensifiers.
9873 Avoid "will" as an auxiliary.
9874 (Limitations of Make): Split this node into....
9875 (Portable Make, $< in Ordinary Make Rules, Failure in Make Rules):
9876 (Leading _ in Macro Names, Backslash-Newline-Newline):
9877 (Backslash-Newline Comments, Long Lines in Makefiles):
9878 (Macros and Submakes, The Make Macro SHELL, Comments in Make Rules):
9879 (obj/ and Make, make -k Status, VPATH and Make):
9880 (VPATH and Double-colon, $< in Explicit Rules):
9881 (Automatic Rule Rewriting, OSF/Tru64 Directory Magic):
9882 (Make Target Lookup, Single Suffix Rules, Timestamps and Make):
9883 New nodes, resulting from splitup of Limitations of Make.
9884 All cross-references changed. Raise the top node from
9885 a section to a chapter, and all subnodes accordingly.
9886 Redo the introductory wording to match the new organization.
9887 (Installation Directory Variables): Use an example that is
9888 closer to what Autoconf actually does. Mention that VPATH's
9889 value should not contain metacharacters or white space.
9890 (Fortran Compiler): Fix a VPATH bug in an example.
9891 (Leading _ in Macro Names): Mention that this problem is no longer
9892 of practical concern.
9893 (VPATH and Make): Reword the advice to make it clearer
9894 that Autoconf and Automake support VPATH in non-GNU make, but
9895 many packages have bugs in this area.
9896 ($< in Explicit Rules): Refer to Build Directories rather
9897 than using a (non-VPATH-safe) example.
9898 (Automatic Rule Rewriting): Mention the sort of disaster that
9899 can ensue with Solaris-style rule rewriting with VPATH.
9901 2006-06-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9903 * doc/install.texi (Compilers and Options): Weaken the
9904 suggestion to use GNU make for VPATH builds.
9906 * lib/autom4te.in (Automake-preselections): Add AM_PROG_CXX_C_O,
9907 AM_PROG_F77_C_O, AM_PROG_FC_C_O, AC_FC_SRCEXT, AC_FC_FREEFORM.
9909 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Fix M4 quotation
9910 in regular expression.
9912 2006-06-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9914 * doc/autoconf.texi (Installation Directory Variables):
9915 Drop extra @samp from `@table @samp' item.
9916 (Limitations of Usual Tools): Comment fix.
9917 Do not nest @samp just to point to other table items.
9918 (Writing testsuite.at) <AT_CHECK>: The second argument to
9919 `@dvar' is already @samp'ed.
9920 (Making testsuite Scripts) <AC_CONFIG_TESTDIR>: Likewise,
9921 do not use @var in the second argument.
9923 2006-06-07 Paul Eggert <eggert@cs.ucla.edu>
9925 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Look for
9926 $as_shell.exe too. Problem reported by Andreas Buening in
9927 <http://lists.gnu.org/archive/html/autoconf/2006-06/msg00038.html>.
9929 2006-06-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9931 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA): Work around
9932 `unused variable' compiler warning, for `-Wall -Werror'.
9933 Reported by Jaap Haitsma in
9934 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00012.html>.
9936 2006-06-06 Paul Eggert <eggert@cs.ucla.edu>
9938 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Remove core file, in
9939 case the compiler dumps core. Problem reported for
9940 OpenServer 5.0.7 by Tim Rice in
9941 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00019.html>.
9942 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE):
9945 2006-06-06 Tim Rice <tim@multitalents.net>.
9947 * lib/freeze.mk: Quiet check-forbidden-patterns so the string
9948 "ERROR" only shows up in "make check" output if there is an
9951 2006-06-06 Eric Blake <ebb9@byu.net>
9953 * tests/tools.at (automatically allowed tokens): Fix typo.
9955 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
9957 * NEWS: Don't blame non-GNU VPATH compatibility issues on Automake.
9959 * doc/autoconf.texi (Integer Overflow): Mention that INT_MIN % -1
9960 typically overflows on x86 CPUs, even though the C standard
9963 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9965 * configure.ac (AC_INIT): Bump to 2.59e.
9968 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9972 * config/texinfo.tex: Sync from upstream.
9974 * bin/autoreconf.in: Trace `LT_CONFIG_LTDL_DIR'; if it has been
9975 seen, invoke libtoolize with `--ltdl' argument.
9976 * lib/autom4te.in (Autoreconf-preselections): Adjust.
9978 Suggested by Eric Blake.
9980 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
9982 * NEWS: Whoops! AC_FUNC_STRNLEN isn't obsolescent. Problem
9983 reported by Ralf Wildenhues.
9984 * doc/autoconf.texi (AC_FUNC_STRNLEN): Likewise.
9986 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9990 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
9992 * doc/autoconf.texi: Modernize some of the references to Solaris.
9994 2006-06-05 Stepan Kasal <kasal@ucw.cz>
9996 * lib/m4sugar/m4sugar.m4 (m4_require): Modify the error
9997 message issued by AC_REQUIRE.
9998 * tests/m4sugar.at: Check m4_require's error message.
9999 * tests/base.at: Check AC_REQUIRE's error message.
10000 * tests/local.at (AT_CHECK_M4): New macro, almost identical
10002 (AT_CHECK_AUTOM4TE): ... which is now a thin wrapper around
10004 (AT_CHECK_AUTOCONF): Use AT_CHECK_M4; no longer support
10005 `expout' as the last parameter.
10006 * tests/tools.at: Adapt to the above change.
10008 2006-06-04 Stepan Kasal <kasal@ucw.cz>
10010 * doc/autoconf.texi (Limitations of Usual Tools): Correct
10011 information about race-free implementations of mkdir.
10013 2006-06-04 Eric Blake <ebb9@byu.net>
10015 * bin/autoreconf.in (help): Document M4 environment variable.
10016 * bin/autoconf.as (Usage): Likewise.
10017 * bin/autom4te.in (help): Likewise.
10018 * doc/autoconf.texi (autom4te Invocation): Likewise.
10020 2006-06-04 Paul Eggert <eggert@cs.ucla.edu>
10022 * NEWS: GNU make now recommended for VPATH builds.
10023 Mention that some macros are now documented to be obsolescent.
10024 * doc/autoconf.texi:
10025 Prefer "current" to "modern" to describe
10026 currently-used (albeit perhaps old-fashioned) hosts.
10027 Mention which ancient features no longer need to be worried about.
10028 setgid -> set-group-ID
10029 setuid -> set-user-ID (these are the Posix terms)
10030 Fix some misuses of "only".
10031 (AC_C_BACKSLASH_A, AC_C_CONST, AC_C_PROTOTYPES):
10032 (AC_C_STRINGIZE, AC_C_VOLATILE, AC_FUNC_CLOSEDIR_VOID):
10033 (AC_FUNC_GETPGRP, AC_FUNC_LSTAT, AC_FUNC_MEMCMP):
10034 (AC_FUNC_SELECT_ARGTYPES, AC_FUNC_SETPGRP):
10035 (AC_FUNC_SETVBUF_REVERSED, AC_FUNC_STAT, AC_FUNC_STRFTIME):
10036 (AC_FUNC_STRNLEN, AC_FUNC_UTIME_NULL, AC_FUNC_VPRINTF):
10037 (AC_HEADER_DIRENT, AC_HEADER_STAT, AC_HEADER_STDC):
10038 (AC_HEADER_SYS_WAIT, AC_HEADER_TIME, AC_ISC_POSIX):
10039 (AC_PROG_GCC_TRADITIONAL, AC_STRUCT_TM):
10040 Mention that these macros are obsolescent.
10041 (Installation Directory Variables): shall -> should
10042 (File Descriptors): Mention that 0, 1, 2 might get reopened.
10043 Mention that it's now safe to use 3 and 4.
10044 (Limitations of Usual Tools): cp -r is now specified by Posix.
10045 Omit longwinded and obsolescent discussion of cp -f.
10046 Modernize discussion of expr, ls.
10047 (Limitations of Make): Modernize discussion of VPATH builds.
10048 Mention $? as a workaround in some cases.
10049 * doc/install.texi (Basic Installation):
10050 Mention "./configure; make; make install" first. Be more
10051 specific about why this file is generic. Remove unnecessary
10052 parens. Remove misleading "only". Remove obsolete advice
10053 about csh. Don't say "configure" takes awhile; say it
10054 might take a while. Suggest CFLAGS=-g rather than CFLAGS=-O2,
10055 and CC=c99 rather than CC=c89, as these are blessed by current
10056 Posix. Recommend GNU make if doing a VPATH build.
10058 2006-06-03 Paul Eggert <eggert@cs.ucla.edu>
10060 * doc/autoconf.texi: Use a consistent style "$ @kbd{...}" for
10061 examples involving shell prompts.
10063 2006-06-02 Stepan Kasal <kasal@ucw.cz>
10064 and Paul Eggert <eggert@cs.ucla.edu>
10066 * doc/autoconf.texi (Here-Documents): Add details about the
10067 pre-ksh93g bug. Reword slightly to make it clearer. Consistently
10068 use "here-documents" instead of "here documents".
10070 2006-06-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10072 * config/texinfo.tex, doc/standards.texi: Sync from upstream.
10074 2006-06-01 Paul Eggert <eggert@cs.ucla.edu>
10076 * doc/autoconf.texi (File System Conventions): Warn about ":"
10077 anywhere in directory names.
10079 2006-05-31 Paul Eggert <eggert@cs.ucla.edu>
10081 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be even more conservative
10082 about quoting the case statement, just in case.
10083 * doc/autoconf.texi (Here-Documents): Mention that the ksh bug
10084 was fixed in ksh93g; reported by Ralf Wildenhues.
10086 2006-05-31 Stepan Kasal <kasal@ucw.cz>
10088 * doc/autoconf.texi (System Services): Do not document
10089 overriding EXEEXT via ac_cv_exeext=ext.
10090 (Particular Programs) <AC_PROG_MKDIR_P>:
10091 Document that ${MKDIR_P} understands --.
10092 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Improve the
10095 2006-05-31 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10097 * lib/m4sugar/m4sh.m4 (_AS_DIRNAME_PREPARE): Guard against test
10098 argument with leading hyphen. Problem reported by Paul Eggert.
10100 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
10102 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be more conservative
10103 about quoting ac_try: quote all of it, if any of it seems suspicious.
10104 This means we don't have to worry about ${ or sed any more.
10105 Also, double-quote the case statement, to work around misuses via
10106 underquoting as reported by Ralf Wildenhues in
10107 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00169.html>.
10108 (_AC_EVAL_STDERR): Revert, since evidently some packages rely on this
10109 undocumented and dangerous macro.
10110 Problem reported by Ralf Wildenhues in
10111 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00168.html>.

10115 * lib/m4sugar/m4sh.m4 (_AS_DIRNAME_PREPARE): Check whether
10116 `dirname -- /' returns `/', for SunOS dirname scripts that escaped.
10117 Report by Sam Sirlin <sam@kalessin.jpl.nasa.gov>.
10119 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
10121 * lib/autoconf/general.m4: Revert AC_TRY_EVAL and AC_TRY_COMMAND,
10122 since evidently some packages rely on the old, broken behavior.
10123 Problem reported by Ralf Wildenhues in
10124 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00160.html>.
10125 (AC_TRY_EVAL, AC_TRY_COMMAND, _AC_EVAL): Go back to the
10126 pre-2006-05-26 definitions, but leave in the comments that
10127 these macros are dangerous and should not be used.
10128 (_AC_DO_ECHO): Renamed from _AC_EVAL_ECHO. All callers changed.
10129 (_AC_DO): Renamed from _AC_EVAL. All callers changed.
10130 (_AC_DO_STDERR): Renamed from _AC_EVAL_STDERR. All callers changed.
10131 (_AC_DO_VAR): Renamed from AC_TRY_EVAL.
10132 (_AC_DO_TOKENS): Renamed from AC_TRY_COMMAND.
10134 2006-05-29 Paul Eggert <eggert@cs.ucla.edu>
10136 * lib/autoconf/status.m4 (AC_OUTPUT_MAKE_DEFS): Rewrite to avoid
10137 the use of 'tr', since this is our only use of 'tr'.
10139 2006-05-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10140 and Paul Eggert <eggert@cs.ucla.edu>
10142 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE):
10143 Don't assume 'grep' works on long lines, since AIX grep doesn't.
10145 2005-05-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10147 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Do not use `grep' on
10148 the output file in the `${datarootdir}' test.
10150 2005-05-28 Stepan Kasal <kasal@ucw.cz>
10151 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10153 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If we have not seen
10154 mention of `datarootdir' in the input file(s), but literal
10155 `${datarootdir}' in the output file, and we haven't warned yet,
10156 then warn as well: the user may have (erroneously) used
10157 `AC_SUBST([mydatadir], [$datadir/my])' instead of the correct
10158 `AC_SUBST([mydatadir], ['${datadir}/my'])'.
10159 * tests/torture.at (datarootdir workaround): Extend this test.
10162 2006-05-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10163 and Paul Eggert <eggert@cs.ucla.edu>
10165 * doc/autoconf.texi (autoheader Invocation): The first argument to
10166 `AC_DEFINE_UNQUOTED' need not be a literal. Mention the
10167 alternatives and clear up the language a bit.
10169 2006-05-27 Paul Eggert <eggert@cs.ucla.edu>
10171 * NEWS: Reword notice for AC_TRY_COMMAND, AC_TRY_EVAL,
10172 ac_config_guess, ac_config_sub, ac_configure.
10173 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
10174 Fix typo that prevented an unnecessary space from being removed.
10175 Problems reported by Ralf Wildenhues in:
10176 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00143.html
10178 2006-05-26 Paul Eggert <eggert@cs.ucla.edu>
10180 * doc/autoconf.texi (Particular Programs, Limitations of Usual Tools):
10181 Use better wording to talk about AC_PROG_MKDIR_P's thread-safety.
10182 Don't use the term "thread-safe" to talk about mkdir race
10183 conditions, since the problem is more a process than a thread
10184 issue. Problem reported by Stepan Kasal in:
10185 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00088.html
10186 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Use code that mimics
10187 the test for 'install' more closely. Look at MKDIR_P first.
10188 Look in the PATH, and at /opt/sfw/bin.
10189 Look for a 'gmkdir' program as well (Solaris 10 /opt/sfw/bin/gmkdir).
10190 Don't bother to try mkdir -p, since we already check mkdir --version;
10191 just look at the version number. (There's no easy way to check
10192 for race-free implementations.)
10193 * tests/tools.at (autoconf: subdirectories): Adjust to above
10194 changes, since MKDIR_P now might end in "/mkdir -p".
10196 * doc/autoconf.texi (autoheader Invocation): Mention that the
10197 first arg of AC_DEFINE_UNQUOTED must be a literal.
10198 Problem reported by Ben Pfaff in
10199 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00090.html>.
10201 * NEWS: Mention that AC_TRY_COMMAND and AC_TRY_EVAL may be removed.
10202 * doc/autoconf.texi (Special Chars in Variables): New section.
10203 (Preset Output Variables): Warn about special chars in CPPFLAGS.
10204 (Installation Directory Variables): Quote $(datadir) better.
10205 (Limitations of Builtins): Describe some of eval's trickiness.
10207 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Simplify quoting.
10208 * lib/autoconf/fortram.m4 (_AC_PROG_FC_V_OUTPUT): Likewise.
10209 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Put leading space
10210 in front of every arg, not just trailing args. Quote apostrophes.
10211 (_AC_EVAL_ECHO): New macro.
10212 (_AC_EVAL, AC_EVAL_STDERR): Use it. Quote arg of eval.
10213 (AC_TRY_EVAL, AC_TRY_COMMAND): Mention that these macros might get
10215 (_AC_LINK_IFELSE): Use proper rule for shell continuation lines,
10216 exposed by quoting of eval argument. Put the command on line line
10218 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): Use eval more safely.
10219 (_AC_PATH_X, AC_PATH_X): Quote more safely.
10220 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Use eval more safely.
10221 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Don't use eval.
10222 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Minor style change.
10223 Handle special chars in prefix, ac_srcdir, ac_aux_dir.
10224 Use eval more safely.
10225 (_AC_OUTPUT_CONFIG_STATUS): Adjust to above changes.
10226 * lib/m4sugar/m4sh.m4 (AS_VAR_GET): Note that this API needs
10228 * tests/base.at (AC_TRY_COMMAND): Use proper rule for shell continuation
10229 lines, exposed by quoting of eval argument.

10232 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10234 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Drop the
10235 initialization of `ac_cv_exeext', do not override it if it was
10236 already set, unless it was set to `no', for compatibility with
10237 Autoconf-2.13, and comment this.
10238 Do not export `ac_cv_exeext', Libtool hasn't needed this for years.
10239 (_AC_COMPILER_EXEEXT_DEFAULT): Likewise, do not export it.
10240 (_AC_COMPILER_EXEEXT_WORKS, _AC_COMPILER_EXEEXT_CROSS): Typos.
10241 * doc/autoconf.texi (Compilers and Preprocessors) <EXEEXT>:

10255 Clean up _AC_COMPILER_EXEEXT* macros.
10256 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't try to
10257 detect exeext, it will be done by _AC_COMPILER_EXEEXT_O; just set
10258 ac_file to the name of the default output file and call
10259 _AC_COMPILER_EXEEXT_WORKS. Move the definition of ac_files and the
10260 initial `rm' of the candidate files...
10261 (_AC_COMPILER_EXEEXT): ... here and simplify them. Moreover, use
10262 the same list in subsequent `rm' calls, and for the temporary
10263 redefinition of ac_clean_files; call _AC_COMPILER_OBJEXT at the end,
10264 and don't call the other _AC_COMPILER_EXEEXT_* macros directly, use...
10265 (_AC_COMPILER_EXEEXT_TESTS): ... this new macro.
10266 (_AC_COMPILER_EXEEXT_O): Don't export ac_cv_exeext, it's not needed (or
10267 no longer needed) by libtool. Make it a cache check.
10268 (_AC_COMPILER_EXEEXT_CROSS): Remove the comment, it was obviously
10269 copied here by mistake.
10270 (AC_NO_EXECUTABLES): Redefine _AC_COMPILER_EXEEXT_TESTS, not
10271 _AC_COMPILER_EXEEXT.
10272 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX, AC_PROG_OBJC): Do not call
10273 _AC_COMPILER_OBJEXT directly.
10274 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
10276 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10278 * doc/autoconf.texi (Limitations of Usual Tools) < sed (`t')>:
10279 Fix description of how the buggy `sed' works.
10281 2006-05-25 Noah Misch <noah@cs.caltech.edu>
10283 Sync from Automake:
10285 * lib/Autom4te/XFile.pm (lock): Allow EOPNOTSUPP, besides
10286 ENOLCK. Only mention `make -j' when applicable. Only raise
10287 fatal errors when `make -j' is involved. Improve error message.
10289 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10291 * doc/autoconf.texi (Here-Documents): We now know more about
10292 the variable expansion in here documents bug.
10293 Thanks to Tim Rice and Stepan Kasal.
10295 * doc/autoconf.texi (Making testsuite Scripts): Add an example
10296 how to use TESTSUITEFLAGS. Suggested by Eric Blake.
10298 2006-05-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10300 * tests/autotest.at (Multiline command from M4 expansion):
10301 No failure to be expected if the shell quotes newlines in
10302 commands in the `set -x' output. Report by Tim Rice.
10305 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
10307 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Don't use shell
10308 expansion in the here-documents used by config.status, as that
10309 runs afoul of the Korn shell version M-12/28/93d bug described in
10310 the Autoconf manual, and this in turn causes a Coreutils 5.95 build to
10311 fail as described by Tim Rice and diagnosed by Ralf Wildenhues in
10312 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00082.html>.
10314 2006-05-23 Jim Meyering <jim@meyering.net>
10316 * lib/autoconf/functions.m4 (AC_FUNC_LSTAT_FOLLOWS_SLASHED_SYMLINK):
10317 Fix typo introduced with 2006-04-02 change. It reversed the sense
10320 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
10322 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Simplify ac_dA and
10323 ac_dB slightly, to save bytes in the script.
10324 Max out at 50 lines, rather than 96; this is more likely
10325 (though not guaranteed) to avoid obscure 'sed' failures.
10327 2006-05-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10329 * lib/autotest/general.m4 (AT_INIT): UnixWare `tr' may interpret
10330 `tr -d -' as bad option argument. Work around this by deleting
10331 an unrelated character.
10332 Report by Tim Rice <tim@multitalents.net>.
10334 2006-05-22 Paul Eggert <eggert@cs.ucla.edu>,
10335 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
10336 Stepan Kasal <kasal@ucw.cz>
10338 * doc/autoconf.texi (Particular Programs): Do not promise that
10339 we always prefer the GNU version of the program, and that we
10340 search according to PATH; both rules can have exceptions.
10341 Update description of AC_PROG_GREP, AC_PROG_EGREP, AC_PROG_FGREP,
10342 AC_PROG_SED. Move descriptions of limitations
10343 to the Limitations of Usual Tools section.
10344 (Limitations of Usual Tools) <sed>: Mention script length
10345 limitations with Solaris /usr/ucb/sed.
10346 <grep>: Fix wording for empty alternative. Mention that -c and
10347 -l should not be combined, and that -E and -F should not be
10350 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
10351 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10353 * lib/autoconf/programs.m4 (AC_PROG_SED): Catch script length
10354 limits in Solaris 8 /usr/ucb/sed by testing a long script.
10356 2006-05-22 Stepan Kasal <kasal@ucw.cz>
10358 * doc/autoconf.texi (Defining Symbols): Literal parameter of
10359 AC_DEFINE is now passed to m4_pattern_allow.
10360 * NEWS: Mention that; likewise for AC_SUBST.
10361 * lib/autoconf/general.m4 (AC_DEFINE_TRACE_LITERAL): Pass
10362 the parameter to m4_pattern_allow.
10363 * tests/tools.at: Add a check for that.
10365 2006-05-22 Stepan Kasal <kasal@ucw.cz>
10367 * lib/autoconf/status.m4: Fix typos.
10369 2006-05-21 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10371 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Remove
10372 only the files that this macro generates.
10374 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
10376 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: For
10377 the HP-UX sed limitation of 99 commands, labels do not count.
10378 * lib/autoconf/status.m4 (_AC_SED_CMD_LIMIT): Mention that
10380 (_AC_OUTPUT_HEADER): Revert the change from 2006-05-19.
10382 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
10384 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT):
10385 Import the following fix from coreutils:
10387 2006-01-13 Jim Meyering <jim@meyering.net>
10389 Invoke AC_CHECK_FUNCS(getmntent) unconditionally so that tests of
10390 $ac_cv_func_getmntent (e.g., in gl_LIST_MOUNTED_FILE_SYSTEMS) need
10391 not double-quote uses of that variable, to accommodate the rare
10392 case in which getmntent is available in none of the libraries
10393 checked. This happens at least on FreeBSD 5.0.
10395 2006-05-20 Paul Eggert <eggert@cs.ucla.edu>
10397 * lib/autoconf/general.m4 (AC_CONFIG_AUX_DIRS): Bring back
10398 ac_config_guess, ac_config_sub, and ac_configure, since evidently
10399 some other programs unwisely rely on these undocumented vars.
10400 But put in warning comments about them.
10401 Problem reported by Ralf Wildenhues in
10402 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00068.html>.
10403 * NEWS: Document that these variables are intended to go away.
10405 2006-05-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10407 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): Require AC_PROG_CXX,
10408 and set the language to C++ (analogous to the equivalent Fortran
10411 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): New macro.
10412 * doc/autoconf.texi (C++ Compiler): Document it.
10413 * lib/autoconf/fortran.m4 (_AC_PROG_FC_C_O): Adjust comment.
10416 2006-05-19 Paul Eggert <eggert@cs.ucla.edu>
10418 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Fix off-by-one bug
10419 that caused config.status to generate 100-command sed scripts; the
10420 portable limit is 99.
10422 2006-05-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10424 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Name temporary
10425 variable `ac_d' instead of `d' to avoid infringing namespace.
10426 Report by Ralf Menzel.
10428 2006-05-18 Paul Eggert <eggert@cs.ucla.edu>
10430 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Don't prepend
10431 $ac_top_build_prefix to $MKDIR_P if it's just 'mkdir -p'.
10432 * tests/tools.at (autoconf: subdirectories): New test, taken from
10433 the corresponding problem report by Ralf Wildenhues in:
10434 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00053.html
10436 * lib/autoconf/functions.m4 (AC_REPLACE_FNMATCH, AC_FUNC_FNMATCH_GNU):
10437 Quote some uses of shell variables if they might suffer unexpected
10438 globbing. This doesn't fix all instances of quoting problems that
10439 I found, just the easy ones that look safe.
10440 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR, _AC_INIT_HELP):
10441 (AC_CONFIG_AUX_DIR, AC_CONFIG_AUX_DIR_DEFAULT, AC_CONFIG_AUX_DIRS):
10442 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST, AC_CANONICAL_TARGET):
10443 (AC_CACHE_LOAD, AC_CACHE_SAVE): Likewise.
10444 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF, _AC_PATH_X_DIRECT): Likewise.
10445 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Likewise.
10446 * lib/autoconf/status.m4 (_AC_OUTPUT_LINK, _AC_OUTPUT_SUBDIRS):
10448 * lib/autotest/general.m4 (_AC_INIT_PARSE_ARGS): Likewise.
10449 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Likewise.
10451 2006-05-18 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10453 * bin/autoreconf.in ($help): Reword according to the manual.
10454 Suggested by Olly Betts.
10456 2006-05-17 Olly Betts <olly@survex.com> (tiny change)
10457 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10459 * bin/autoreconf.in: Pass the directory argument to
10460 `require_configure_ac'. Fix comment.
10461 * tests/torture.at (Configuring subdirectories): Expose this.
10462 Reported by Olly Betts.
10464 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10466 * lib/Automake/Configure_ac.pm, lib/Automake/Channels.pm,
10467 lib/Automake/FileUtils.pm, lib/Automake/Struct.pm: Sync from
10468 Automake as follows:
10470 * lib/Autom4te/Configure_ac.pm (find_configure_ac): Use
10471 `$configure_in' instead of `configure.in', to preserve
10472 directory component.
10474 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10476 * config/config.guess, config/config.sub, config/texinfo.tex,
10477 doc/make-stds.texi, doc/standards.texi: Sync from upstream.
10479 2006-05-14 Paul Eggert <eggert@cs.ucla.edu>
10481 * lib/autoconf/headers.m4 (AC_HEADER_STDBOOL): Fix overly-picky
10482 test for C99 conformance; (bool) 0.5 is an integer constant
10483 expression, but (bool) -0.5 is not. Problem reported by Fedor
10484 Sergeev in <http://forum.sun.com/jive/thread.jspa?threadID=96202>.
10486 2006-05-13 Paul Eggert <eggert@cs.ucla.edu>
10488 * doc/autoconf.texi (Particular Programs): AC_PROG_MKDIR_P now
10489 sets MKDIR_P, not mkdir_p, to avoid collisions with Automake.
10490 Warn about obsolete install-sh files. Remove stray sentence
10491 fragment and fix cross reference.
10492 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Don't insist on
10493 install -d; this undoes the 2006-05-10 change.
10494 (MKDIR_P): Mark with AN_MAKEVAR.
10495 (AC_PROG_MKDIR_P): Fall back on $ac_install_sh, not $INSTALL, so
10496 that we don't require $INSTALL to be thread-safe. Move comments
10497 out of generated code. Require AC_CONFIG_AUX_DIR_DEFAULT instead
10498 of AC_PROG_INSTALL. Output a message saying that we're checking
10499 mkdir -p. Set MKDIR_P rather than mkdir_p. Do special magic for
10500 MKDIR_P instead of AC_SUBST.
10501 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE, _AC_OUTPUT_CONFIG_STATUS):
10502 Special magic for MKDIR_P, too.
10503 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Remove comment that defeated
10505 * tests/local.at (AT_CHECK_ENV): mkdir_p -> MKDIR_P.
10507 2006-05-11 Paul Eggert <eggert@cs.ucla.edu>
10509 Sync from Automake, as follows:
10511 2006-05-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10512 * config/install-sh: Initialize IFS, so field splitting isn't
10514 * config/mkinstalldirs: Likewise.
10515 * config/missing: Remove superfluous quotes. Replace all uses of
10516 `[' by `test', for consistency, and for..
10517 * config/missing (sed_minuso, sed_output): New variables.
10518 (autom4te, help2man, makeinfo): Use them. Unifies detection of
10519 `-o FILE', `--output FILE', `--output=FILE', stricter regex.
10520 Fixes `missing' to detect `--output' for help2man. Fixes
10521 PR automake/483. Report by Dennis J. Linse.
10522 (autom4te): Document in `missing --help'.
10524 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
10526 * NEWS: New macro AC_PROG_MKDIR_P. AS_MKDIR_P is now more robust.
10527 * config/install-sh: Don't use 'path' to talk about file names,
10528 as per GNU coding standards. Close a race condition reported by Ralf
10529 Wildenhues and Stepan Kasal. There is still a race condition
10530 on hosts that predate Posix 1003.1-1992, but we can't help this.
10531 Don't mishandle weird characters like space on pre-Posix hosts.
10532 Invoke mkdir at most once per dir arg on pre-Posix hosts.
10533 * doc/autoconf.texi (Programming in M4sh): Cross-reference to
10534 AC_PROG_MKDIR_P from AS_MKDIR_P.
10535 (Limitations of Usual Tools): Cross-reference to AC_PROG_MKDIR_P
10536 from mkdir. Mention that Autoconf 2.60 install-sh is safe but
10537 earlier editions are not (including Automake 1.8.3).
10538 Do not suggest mkinstalldirs for thread-safety.
10539 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Insist on an 'install'
10540 that understands -d, so that AC_PROG_MKDIR_P can fall back on $INSTALL.
10541 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Make it more robust in the
10542 presence of special characters and race conditions.
10543 * tests/local.at (AT_CHECK_ENV): Add mkdir_p to the list of variables
10544 in Autoconf's name space.
10546 2006-05-10 Bruno Haible <bruno@clisp.org>
10547 and Paul Eggert <eggert@cs.ucla.edu>
10549 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): New macro, taken
10550 from Automake with minor changes.
10551 * doc/autoconf.texi (Particular Programs): Document AC_PROG_MKDIR_P.
10553 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
10555 * config/install-sh: Update to Automake CVS version, as follows:
10556 2006-04-25 Stepan Kasal <kasal@ucw.cz>
10557 * lib/install-sh: Simplify the expr implementation of dirname.
10558 2006-04-24 Paul Eggert <eggert@cs.ucla.edu>
10559 * lib/install-sh: Handle --, and diagnose unknown options.
10561 2006-05-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10563 * tests/Makefile.am (AUTOTEST): Use `$(MY_AUTOM4TE)' instead of
10564 `./autom4te' to create `./testsuite', since the `all' target
10565 will ensure its presence, but `installcheck' should not create
10566 the uninstalled wrappers.
10568 * tests/torture.at (Unusual Automake input files): Skip if we
10569 detect automake < 1.8.
10571 2006-05-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10573 * lib/autoconf/c.m4 (AC_PROG_CC_STDC): If ac_cv_prog_cc_stdc
10574 is set to `no', then that overrides and sets ac_cv_prog_cc_c89
10575 and ac_cv_prog_cc_c99 to `no', for backward compatibility.
10578 2006-05-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10580 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Take care not to
10581 munge (multiple) white space and other oddities.
10582 * tests/torture.at (AT_CHECK_AC_ARG_VAR): Make sure to M4-escape
10583 single quotes in variable assignment.
10584 (AC_ARG_VAR, configure invocation): Adjust tests to expose this
10585 and similar failures by adding multiple spaces, tabs, and other
10586 special characters.
10587 Report and different test suggested by Francesco Romani
10588 <fromani@gmail.com> and Andrew Church <achurch@achurch.org>.
10590 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): When we escape
10591 single quotes, we only need to search for single quotes; this
10592 both simplifies the search pattern, and makes us less
10593 susceptible to `echo' variations for arguments not containing
10595 (_AC_ARG_VAR_VALIDATE): Likewise.
10597 2006-05-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10599 * doc/autoconf.texi (Special Shell Variables) <IFS>: Document
10600 `$*' and IFS concatenation issue with traditional shells and
10601 bash-2.04. Report by Seanster@Seanster.com.
10603 2006-05-03 Bruno Haible <bruno@clisp.org>
10605 * doc/autoconf.texi (Limitations of Usual Tools): Identify more
10606 precisely which Mac OS X versions have the od problem.
10608 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
10610 * doc/autoconf.texi: Use @option systematically.
10612 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
10613 and Bruno Haible <bruno@clisp.org>
10615 * doc/autoconf.texi (Limitations of Usual Tools): Add a paragraph
10617 (Integer Overflow): Mention the special case of integer division
10620 2006-05-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10622 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Cater for
10623 traditional shells like the Solaris one that do not use the
10624 first IFS character for assembling `$*'.
10625 Prompted by a related report from autoconf_bug@nro.ca.
10627 2006-05-01 Paul Eggert <eggert@cs.ucla.edu>
10628 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10630 * doc/autoconf.texi (Limitations of Builtins, Limitations of Make):
10631 Mention more problems with the -e option.
10633 2006-04-30 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10636 * doc/autoconf.texi (Systemology): Mention the Heirloom Project.
10638 * doc/autoconf.texi (Introduction, Pointers): Use `@/' liberally
10639 in URLs to improve DVI formatted output (requires texinfo 4.6).
10640 (System Services, Systemology, Shellology): Likewise.
10641 (Limitations of Usual Tools): Rewrite Mac OS X example for nicer
10644 * doc/autoconf.texi (Fortran Compiler): Do not use `@ovar' in
10646 (Runtime): Fix macro argument names to match description:
10647 `action-if-found' -> `action-if-true' and similarly.
10648 (Obsolete Macros): Likewise.
10649 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE): Likewise.
10650 (AC_COMPILE_IFELSE, AC_TRY_COMPILE, _AC_LINK_IFELSE)
10651 (AC_LINK_IFELSE, AC_TRY_LINK, AC_COMPILE_CHECK): Likewise.
10653 2006-04-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10655 * doc/autoconf.texi (Limitations of Make): Clean up markup.
10658 * doc/autoconf.texi (Portable Shell): Allow wrapped URLs, for

10670 * doc/autoconf.texi (Portable C and C++, Varieties of Unportability):
10671 (Integer Overflow, Null Pointers, Buffer Overruns):
10672 (Floating Point Portability, Exiting Portably): New sections.
10673 (Writing Test Programs): Fix some langauge. Recommend exiting
10674 with status 1, not merely nonzero. Clarify exit declaration.

10683 2006-04-25 Paul Eggert <eggert@cs.ucla.edu>
10685 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Don't use AS_ERROR,
10686 since as_me isn't set yet.
10688 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
10690 Prepare for deprecation of AS_BASENAME and AS_DIRNAME, and fix
10691 a few minor bugs in this area.
10693 * doc/autoconf.texi (Programming in M4sh): Comment out the
10694 documentation of AS_BASENAME, for now.
10695 (Shell Substitutions): Do not use AS_DIRNAME in an example.
10696 (Limitations of Builtins) <basename>: Do not refer to
10698 * bin/autoconf.as (me): Don't use AS_BASENAME.
10699 (dir): Remove the unused variable.
10700 * lib/m4sugar/m4sh.m4 (_AS_DETECT_REQUIRED): Renamed from
10701 AS_DETECT_REQUIRED. All uses changed.
10702 (_AS_DETECT_SUGGESTED): Renamed from AS_DETECT_SUGGESTED.
10704 (_AS_DETECT_BETTER_SHELL): Put ;; at the end of a case.
10705 (AS_BASENAME): Use "basename --" to protect against leading "-".
10706 (_AS_BASENAME_EXPR): Renamed from AS_BASENAME_EXPR. All uses changed.
10707 (_AS_BASENAME_SED): Renamed from AS_BASENAME_SED. All uses changed.
10708 (_AS_BASENAME_PREPARE): Reject implementations that cannot handle "--".
10709 (_AS_DIRNAME_PREPARE): Likewise.
10710 (_AS_DIRNAME_EXPR): Renamed from AS_DIRNAME_EXPR. All uses changed.
10711 (_AS_DIRNAME_SED): Renamed from AS_DIRNAME_SED. All uses changed.
10712 (AS_DIRNAME): Use "dirname --".
10714 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
10716 * doc/autoconf.texi (Runtime): Renamed from "Run Time". All uses
10717 of "run time" and "run-time" changed to "runtime", for consistency.
10718 * lib/autoconf/fortran.m4: Likewise (in comment).
10719 * lib/autoconf/functions.m4: Likewise.
10720 * lib/autoconf/general.m4: Likewise.
10721 * lib/autoconf/headers.m4: Likewise.
10723 * doc/autoconf.texi (Run Time): Document the exit status situation
10724 with more accuracy and detail.
10726 2006-04-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10728 * doc/autoconf.texi (Introduction): The GNU Autoconf Macro
10729 Archive is not officially `GNU' any more. Update URL.
10730 (Defining Directories): Likewise
10731 * lib/autoconf/c.m4 (AC_C_RESTRICT): Update URL.
10733 2006-04-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10735 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Remove the leading
10736 newline from the `trap' code to finish `config.log'; the NetBSD
10737 /bin/sh resets the exit status after an empty command, as
10738 documented in doc/autoconf.texi.
10739 Reported by Dalibor Topic <robilad@kaffe.org>.
10741 2006-04-19 Paul Eggert <eggert@cs.ucla.edu>
10743 * doc/autoconf.texi (C Compiler): Clarify AC_C_TYPEOF.
10744 Suggested by Bruno Haible.
10746 2006-04-18 Paul Eggert <eggert@cs.ucla.edu>
10748 * configure.ac (ac_cv_sh_n_works): Don't try to test for it, since
10749 some shells (e.g., Solaris 8 /bin/sh) implement it verrrry slowly.
10750 Instead, just list the shells that we know work.
10751 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Remove 2nd arg. All uses
10752 changed. Be more cautious about the _cv_ variable.
10753 * tests/tools.at (Syntax of the shell scripts): Check the
10754 _cv_ variable once, at first, to avoid an internal autoconf error
10755 when sh -n does not work.
10757 2006-04-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10759 * lib/Autom4te/FileUtils.pm: Sync from Automake.
10761 2006-04-16 Paul Eggert <eggert@cs.ucla.edu>
10763 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Don't
10764 use ">&-" since we're only 99.999% sure that this is portable,
10765 and since the MinGW bug is fixed in a different way.
10766 * lib/autotest/general.m4 (AT_INIT): Likewise.
10768 2006-04-16 Stepan Kasal <kasal@ucw.cz>
10770 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Handle --recheck
10771 before opening config.log, to avoid hitting a bug on MinGW.
10773 2006-04-14 Paul Eggert <eggert@cs.ucla.edu>
10775 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Close
10776 AS_MESSAGE_LOG_FD before reopening it onto the log file.
10777 This works around a MinGW bug reported by Eric Paire.
10778 Make sure that all writes to the log file append to it,
10779 rather than possibly losing data.
10780 * lib/autotest/general.m4 (AT_INIT): Likewise.
10782 2006-04-14 Stepan Kasal <kasal@ucw.cz>
10784 * lib/Autom4te/FileUtils.pm (find_file): Fix a typo in the
10787 2006-04-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10791 * configure.ac (AC_INIT): Bump to 2.59d.
10793 2006-04-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10797 * Makefile.maint (news-date-check): Do not require a leading `*'
10798 before the release date in NEWS.
10800 2006-04-12 Stepan Kasal <kasal@ucw.cz>
10801 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10803 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If the templates for
10804 the instantiated file do not contain the string 'datarootdir'
10805 but contain @datadir@, @docdir@, @infodir@, @localedir@, or
10806 @mandir@, replace the reference '${datarootdir}' by the value.
10807 * tests/torture.at (datarootdir workaround): New test.
10808 * NEWS: Advertise this temporary fixup.
10809 Based on a patch by Bruno Haible, reported and analyzed by
10810 Paul Eggert and Noah Misch.
10812 2006-04-12 Eric Blake <ebb9@byu.net>
10814 * tests/autotest.at (Debugging a failed test): Fix comment.
10816 2006-04-12 Stepan Kasal <kasal@ucw.cz>
10818 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): Simplify the summary of
10819 all the changes since 2006-04-07.
10821 2006-04-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10823 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): If `ln -s file1 file2'
10824 succeeded, but `ln -s file dir' failed, take care to remove the
10825 leftover target before the next test, to prevent its spurious
10826 failure; also make sure `ln file dir' works before selecting it.
10827 Thanks to Keith Marshall for pointing this out.
10830 * lib/autotest/general.m4 (AT_INIT): Store quoted variable
10831 assignments in `at_debug_args', so that we put them correctly
10832 in the `run' script.
10833 * tests/autotest.at (Debugging a failed test): Unmark XFAIL.
10834 Reported by Eric Blake.
10836 2006-04-11 Eric Blake <ebb9@byu.net>
10838 * tests/autotest.at (AT_CHECK_AT): Add new argument, to allow
10839 top-level tests after micro-suite has been run. Used in...
10840 (Debugging a successful test, Debugging script and environment),
10841 (Debugging a failed test): ...these new tests. The first of these
10843 * lib/autotest/general.m4 (_AT_CREATE_DEBUGGING_SCRIPT): New
10844 macro, split out from...
10845 (AT_INIT): ...here, so that using -d also generates a run script.
10846 Document that -d inhibits top-level logging.
10847 * doc/autoconf.texi (testsuite Invocation): Document that -d only
10848 inhibits top-level logging; debug scripts are created.
10850 * lib/autotest/general.m4 (_AT_CHECK): Avoid syntax error on empty
10852 * tests/autotest.at (Empty test, Empty check): New test to check it.
10854 * lib/autoconf/c.m4 (AC_C_CONST, AC_C_VOLATILE): Avoid warnings
10857 2006-04-10 Stepan Kasal <kasal@ucw.cz>
10859 * tests/mktests.sh: Use "trap '' 0", not "trap 0". Do not touch
10860 the files if a problem appears. Make the empty *.at files
10861 read-only, too. Proposed by Ralf Wildenhues.
10863 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10865 * config/Makefile.am: Add comment to force updated Makefile.in.
10867 * lib/freeze.mk: Fix typo in comment. Unlike the last, white
10868 space only patch to this file, this patch causes the Makefile.in
10869 files that include freeze.mk to be updated, and thus have a
10870 newer time stamp again, which in turn makes a pristine CVS
10871 checkout have correct time stamps.
10873 * Makefile.maint (cvs-sv): New macro, to be used..
10874 (config.guess-url_prefix, config.sub-url_prefix)
10875 (texinfo.tex-url_prefix, standards.texi-url_prefix): ..here;
10876 point to CVS text checkout of Gnulib files.
10877 (copyright-check): Bump current year.
10878 (announcement): Do not hard-wire `./announce-gen'.
10879 (cvs-update): Propagate failures of `cvs' and `move-if-change'
10881 * Makefile.cfg (executable-update): Use `chmod a+x' instead of
10883 (wget_files): Update config.guess, config.sub, texinfo.tex by
10884 `wget-update', now that their URLs work again.
10886 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
10888 * doc/autoconf.texi (Particular Types): Don't use AC_CHECK_TYPE.
10889 Problem noted by Paul D. Smith.
10891 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10893 * doc/autoconf.texi: Remove unused words from word list.
10894 * .x-sc_prohibit_atoi_atof, .x-sc_space_tab, .x-sc_sun_os_names,
10895 .x-sc_trailing_space: New files.
10897 * doc/standards.texi: Sync from gnulib.
10899 * NEWS, doc/autoconf.texi (AC_LIBOBJ vs LIBOBJS): Mark
10900 `LIBOBJDIR' as experimental.
10902 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): MSYS `ln -s' fails
10903 with a target directory; it's internally implemented as `cp'
10904 anyway, but since Autoconf advertises the possibility to use
10905 a target directory when LN_S is `ln -s', we need to find out.
10906 Reported by Rolf Ebert <rolf.ebert.gcc@gmx.de> against MSYS,
10907 analyzed by Keith Marshall <keith.marshall@total.com>.
10911 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
10913 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Just output
10914 confdefs.h as-is. In general, if it has backslash-newline or the
10915 like, then it doesn't work either to sort or to remove empty
10918 2006-04-09 Stepan Kasal <kasal@ucw.cz>
10920 * tests/Makefile.am (AUTOCONF_FILES): Fix typo in the comment.
10922 2006-04-09 Alexandre Duret-Lutz <adl@gnu.org>
10924 * lib/autom4te.in (Automake-preselections): Preselect
10927 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>
10929 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Use '\'' for an
10930 apostrophe within a single-quoted string, as this is the usual
10931 tradition and is easier to read than '"'"'. Don't rely on the
10932 shell treating "$/" like '$/'. Use a more-consistent indenting
10933 style for the trap.
10935 2006-04-09 Eric Blake <ebb9@byu.net>
10937 * tests/autotest.at (Backquote command substitution),
10938 (Multiline backquote command substitution): Remove mistaken
10939 AT_NO_CMDSUBST from the 2006-03-14 patch, which was meant to be
10941 (Parenthetical command substitution, Multiline parenthetical
10942 command substitution): here.
10944 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>
10946 Import macros from gnulib (often changing their name).
10948 * NEWS: AC_C_TYPE_LONG_DOUBLE is now obsolete.
10949 New macros AC_CHECK_DECLS_ONCE, AC_CHECK_FUNCS_ONCE,
10950 AC_CHECK_HEADERS_ONCE, AC_FUNC_STRTOLD, AC_HEADER_ASSERT,

10960 (Pointers): Add Gnulib URL.
10961 (Particular Functions): Alphabetize. Add AC_FUNC_STRTOLD.
10962 (Generic Functions): Add AC_CHECK_FUNCS_ONCE. Refer to new
10964 (Particular Headers): Add AC_HEADER_ASSERT. For stdbool.h,
10965 suggest a #define rather than a typedef for _Bool, and mention
10966 Gnulib rather than trying to substitute stdbool code.
10967 (Generic Headers): Add AC_CHECK_HEADERS_ONCE.
10968 (Generic Declarations): Add AC_CHECK_DECLS_ONCE.
10969 (Particular Structures): Add AC_STRUCT_DIRENT_D_INO,
10970 AC_STRUCT_DIRENT_D_TYPE.

10973 Add AC_TYPE_INT8_T, AC_TYPE_INT16_T, AC_TYPE_INT32_T, AC_TYPE_INT64_T,
10974 AC_TYPE_INTMAX_T, AC_TYPE_INTPTR_T, AC_TYPE_LONG_DOUBLE,
10975 AC_TYPE_LONG_DOUBLE_WIDER, AC_TYPE_LONG_LONG_INT, AC_TYPE_UINT8_T,
10976 AC_TYPE_UINT16_T, AC_TYPE_UINT32_T, AC_TYPE_UINT64_T,
10977 AC_TYPE_UINTMAX_T, AC_TYPE_UINTPTR_T, AC_TYPE_UNSIGNED_LONG_LONG_INT.
10978 (C Compiler): Move AC_C_LONG_DOUBLE to ...
10979 (Obsolete Macros): here. Under AC_LONG_DOUBLE, mention
10980 AC_TYPE_LONG_DOUBLE or AC_TYPE_LONG_DOUBLE_WIDER instead.
10981 (Posix Variants): Add AC_USE_SYSTEM_EXTENSIONS.
10982 (Coding Style). Don't mention m4_expand_once.
10983 * lib/autoconf/c.m4 (AC_C_LONG_DOUBLE): Implement via
10984 AC_TYPE_LONG_DOUBLE_WIDER. Now obsolete.
10985 * lib/autoconf/functions.m4 (_AH_CHECK_FUNCS): New macro.
10986 (AC_CHECK_FUNCS): Use it.
10987 (AC_CHECK_FUNCS_ONCE, AC_FUNC_STRTOLD): New macros.
10988 (AC_FUNC_WAIT3): "the Open Group standards" -> "POSIX".
10989 * lib/autoconf/general.m4 (AC_CHECK_DECLS_ONCE): New macro.
10990 * lib/autoconf/headers.m4 (AC_CHECK_HEADERS_ONCE): New macro.
10991 (AC_HEADER_ASSERT): New macro.
10992 (AC_HEADER_STDBOOL): Don't assume "#error" works.
10993 Catch a bug in IBM AIX xlc compiler version 6.0.0.0.
10994 Catch a bug in an HP-UX C compiler.
10995 * lib/autoconf/specific.m4 (AC_USE_SYSTEM_EXTENSIONS): New macro.
10996 * lib/autoconf/types.m4 (AC_TYPE_INTMAX_T. AC_TYPE_UINTMAX_T):

11000 (_AC_STRUCT_DIRENT, AC_STRUCT_DIRENT_D_INO, AC_STRUCT_DIRENT_D_TYPE):
11003 * tests/mktests.sh (ac_exclude_list, au_exclude_list): Do not
11004 use /^foo|bar$/, it does not mean /^(foo|bar)$/.
11006 2006-04-08 Stepan Kasal <kasal@ucw.cz>
11008 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Fix the wording
11009 of the warning introduced by the 2001-08-28 change.
11011 2006-04-08 Stepan Kasal <kasal@ucw.cz>,
11012 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11014 * lib/autoconf/general.m4 (AC_CACHE_SAVE): All `ac_cv_env_foo'
11015 variables shall be overriden by the cache.
11016 * tests/torture.at (AC_ARG_VAR): Test also with a first value
11017 that contains braces.
11019 2006-04-07 Stepan Kasal <kasal@ucw.cz>
11021 Revert the patch from 2006-04-01 and only improve
11022 _AS_DETECT_BETTER_SHELL:
11024 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Do not optimize; do not
11025 skip nonexistent directories.
11026 (_AS_DETECT_BETTER_SHELL): The optimization is moved here--try
11027 only shell candidates which exist.
11028 (AS_UNAME): No need to give three parameters to _AS_PATH_WALK.
11029 * lib/autotest/general.m4 (AT_INIT): No need to give three
11030 parameters to _AS_PATH_WALK.
11032 2006-04-07 Stepan Kasal <kasal@ucw.cz>,
11033 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11035 * bin/autoupdate.in (handle_autoconf_patches): Change the way we
11036 distinguish m4sugar macros.
11037 * tests/tools.at (autoupdating with aclocal and m4_include):
11038 New test. Bug reported by Gary V. Vaughan <gary@gnu.org>,
11039 test case by Noah Misch <noah@cs.caltech.edu>.
11041 2006-04-07 Stepan Kasal <kasal@ucw.cz>
11043 Revert my change from 2006-03-17, in other words:
11044 * lib/m4sugar/m4sh.m4 (AS_BOURNE_COMPATIBLE): Insert BIN_SH=xpg4
11046 (AS_SHELL_SANITIZE): Remove DUALCASE=1.
11047 * doc/autoconf.texi (Special Shell Variables) <BIN_SH>: Say that
11050 2006-04-07 Eric Blake <ebb9@byu.net>
11052 * doc/autoconf.texi (Programming in M4sh): Document that
11053 AS_MKDIR_P exits the script on failure.
11054 * lib/autotest/general.m4: Remove redundant AS_ERROR.
11056 2006-04-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11058 * config/elisp-comp, config/install-sh, config/mdate-sh,
11059 config/missing, config/mkinstalldirs: Sync from Automake.
11061 * lib/Autom4te/FileUtils.pm, lib/Autom4te/Struct.pm: Sync
11064 * doc/make-stds.texi: Sync from gnulib.

11068 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_O): Inside cache
11069 check, s/ac_exeext/ac_cv_exeext/. Fixes regression introduced
11072 2006-04-06 Stepan Kasal <kasal@ucw.cz>,
11073 Eric Blake <ebb9@byu.net>,
11074 Paul Eggert <eggert@cs.ucla.edu>,
11075 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11077 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): Fix the detection of
11078 whether `set' quotes correctly: redirect stderr of the tested
11079 `set', and use a subshell, for Ultrix; use `sed' instead of
11080 `grep' for zsh `set' which may write binary output; match only
11081 at the beginning of a line, to avoid false positives.
11082 In order to avoid false positives by unrelated variables with
11083 multiline content, put the dump algorithm in a subshell and
11084 unset all variables containing newlines (except some which are
11085 special to the shell). Warn about cache variables that are
11088 2006-04-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11090 * config/config.guess, config/config.sub, config/texinfo.tex:
11091 Sync from upstream.
11093 * tests/mktests.sh: Reword comments.
11095 * tests/mktests.sh: Only skip internal macros starting with
11096 `_AC_' or `__AC_'. Noted by Stepan Kasal.
11097 Update exclusion lists for the test suite to this end:
11098 (AC_ARG_VAR): Do test this now.
11099 (AC_SEARCH_LIBS, AC_REPLACE_FUNCS): Need an argument.
11100 (AC_LINKER_OPTION): Remove (renamed to _AC_LINKER_OPTION).
11101 (AC_LIST_MEMBER_OF): Likewise (renamed to _AC_LIST_MEMBER_IF).
11102 (AC_LINK_FILES): Obsoleted since (and thus AU_DEFUN'ed).
11104 * doc/autoconf.texi (Shell Substitutions): Mention the MSYS
11105 shell issue with double-quoted command substitutions of native
11107 Reported to MSYS by Mark Cave-Ayland, to Autoconf by Keith
11110 * Makefile.maint (sc_cast_of_argument_to_free): Do not fail when
11111 no file matches the glob, discard the warning, set `nullglob'.
11112 (syntax-check): Likewise.
11113 (sc_cast_of_x_alloc_return_value): Likewise.
11114 (sc_cast_of_alloca_return_value, sc_error_exit_success)
11115 (sc_prohibit_jm_in_m4, .re-list, sc_unmarked_diagnostics)
11116 (m4-check): Likewise.
11117 (sc_system_h_headers): Do not print rule on execution.
11118 (sc_tight_scope): Do not fail for non-existing `src' directory.
11119 (sc_changelog): Skip the Copyright footer.
11120 * lib/autoconf/lang.m4: Remove trailing space.
11122 * lib/autoconf/status.m4: More replacements to
11123 <tab><space> where this makes sense.
11125 2006-04-06 Stepan Kasal <kasal@ucw.cz>
11127 * tests/Makefile.am (maintainer-check-posix):

11201 Prefer 'sort -u' to 'sort | uniq'. Filter data before sorting it.
11202 Use 'comm' rather than N instances of grep; this also fixes a bug

11298 (_AC_COMPILER_EXEEXT_TESTS): ... this new macro.
11299 (_AC_COMPILER_EXEEXT_O): Don't export ac_cv_exeext, it's not needed (or
11300 no longer needed) by libtool. Make it a cache check.

11302 copied here by mistake.

12037 2005-10-27 Stepan Kasal <kasal@ucw.cz>
12039 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): "conftst2" -> "conftest2"
12040 * lib/autoconf/fortran.m4 (_AC_PROG_FC_C_O): Likewise.
12042 2005-10-25 Stepan Kasal <kasal@ucw.cz>
12044 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): rm -f conftst2.*, not only
12045 conftst2.$ac_objext.
12046 * lib/autoconf/fortran.m4 (_AC_PROG_FC_C_O): Likewise.
12048 2005-10-24 Stepan Kasal <kasal@ucw.cz>
12050 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Use conftst2.o instead of
12051 conftest.o, to see whether the compiler really obeys; rm the object
12052 file before and after the test and register it with ac_clean_files.
12053 * lib/autoconf/fortran.m4 (_AC_PROG_FC_C_O): Likewise.
12055 2005-10-21 Stepan Kasal <kasal@ucw.cz>
12057 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): When determining,
12058 the delimiter CEOF$ac_eof: fix quoting of CEOF[0-9]* and modify the
12059 code so that the most common case requires less forks.
12061 2005-10-20 Stepan Kasal <kasal@ucw.cz>
12063 * doc/autoconf.texi (Shell Substitutions}: Document that ${10} is
12064 not portable; thanks to Paul Eggert and Alexandre.
12066 * NEWS: Fix an old typo.
12068 2005-10-20 Jim Meyering <jim@meyering.net>
12070 * doc/autoconf.texi: Typo: s/feature/features/ in ``the features of
12071 the latter'', in two places.
12073 2005-10-19 Paul Eggert <eggert@cs.ucla.edu>
12075 * doc/autoconf.texi (Generating Sources): AC_LANG_PROGRAMS ->
12076 AC_LANG_PROGRAM, fixing a typo. Don't give details about
12077 the inner workings of AC_LANG_FUNC_LINK_TRY.
12078 * lib/autoconf/c.m4 (AC_LANG_CALL(C)): Reformat to match
12079 AC_LANG_FUNC_LINK_TRY. This involves returning the value returned
12080 by the function rather than ignoring it.
12081 (AC_LANG_FUNC_LINK_TRY(C)): Call the function rather than simply
12082 comparing its address. Intel's interprocedural optimization was
12083 outsmarting the old heuristic. Problem reported by
12086 2005-10-19 Stepan Kasal <kasal@ucw.cz>
12088 * lib/autoconf/general.m4 (AC_SUBST): Remove an obsolete comment.
12090 2005-10-05 Paul Eggert <eggert@cs.ucla.edu>
12092 * lib/m4sugar/m4sugar.m4 (_m4_map): New macro.
12093 (m4_map, m4_map_sep): Use it. Handle the empty list correctly.
12095 2005-10-04 Stepan Kasal <kasal@ucw.cz>
12097 * lib/autotest/general.m4 (AT_INIT): Really make the subtree writable
12098 before removing it (chmod -R u+rwx); there are three instances of this.
12100 2005-10-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
12101 Stepan Kasal <kasal@ucw.cz>
12103 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Balance parentheses.
12104 * lib/autotest/general.m4 (AT_INIT): If the test dir already exists,
12105 make its content writable before removing it. Remove an errorneous
12106 comment from the end, where the logs of the failed tests are copied
12107 to the main log file.
12109 2005-09-27 Stepan Kasal <kasal@ucw.cz>
12111 * tests/semantics.at (AC_C_BIGENDIAN): Pass --force to autoheader,
12112 in case the computer is too quick. Double quote the configure.ac
12115 * tests/local.at (AT_CHECK_AUTOCONF): Always pass --force to prevent
12116 problems if the testsuite were running too fast.
12118 2005-09-18 Paul Eggert <eggert@cs.ucla.edu>
12120 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Look for X11/Xlib.h
12121 and XrmInitialize rather than X11/Intrinsic.h and XtMalloc
12122 (which belong to Xt, not X itself). See Debian bug 327655.
12123 * NEWS: Mention this.
12125 2005-09-07 Stepan Kasal <kasal@ucw.cz>
12127 * lib/autoconf/c.m4 (AC_LANG_SOURCE(C)): Remove an incorrect comment.
12129 2005-09-06 Paul Eggert <eggert@cs.ucla.edu>
12131 * config/move-if-change: Don't output "$2 is unchanged";
12132 suggested by Ben Elliston. Handle weird characters correctly.
12134 2005-09-06 Stepan Kasal <kasal@ucw.cz>
12136 * lib/autoconf/libs.m4 (AC_SEARCH_LIBS): Merge the two AC_LINK_IFELSE
12137 calls, so that the final expansion of this macro is shorter.
12138 Create the conftest.$ac_ext outside the `for' loop, to speed the run.
12139 Do not use `break' in the argument to AC_LINK_IFELSE, it would skip
12140 the cleanup there. Use AS_VAR_* macros, to be more general.
12141 * tests/semantics.at (AC_SEARCH_LIBS): Check for the cleanup.
12143 * lib/autoconf/general.m4: Use AS_IF where appropriate.
12145 * lib/m4sugar/m4sh.m4 (AS_IF): Use m4_default.
12147 2005-09-01 Stepan Kasal <kasal@ucw.cz>
12149 * doc/autoconf.texi (Configuration Headers): Add an index entry
12152 2005-08-26 Pavel Roskin <proski@gnu.org>
12154 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): Use shell variable
12155 XMKMF to locate xmkmf. Make XMKMF precious. Export CC when
12158 2005-08-26 Paul Eggert <eggert@cs.ucla.edu>
12160 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE):
12161 The previous patch didn't work, so try a better one.
12163 2005-08-26 Stepan Kasal <kasal@ucw.cz>
12165 * doc/autoconf.texi (Programming in M4sh) <AS_TR_CPP>: Fix m4 quoting
12166 in the example. Reported by Bruno Haible.
12167 <AS_TR_SH>: Likewise. Also modify the example to be more convincing:
12168 "if $undefined_var;" succeeds with my shell.
12170 * lib/autoconf/general.m4 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST,
12171 AC_CANONICAL_TARGET): Define by AC_DEFUN, no need to use AC_DEFUN_ONCE;
12172 but change the m4_divert_text to m4_divert_once.
12174 2005-08-25 Paul Eggert <eggert@cs.ucla.edu>
12176 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE):
12177 Work around bug in Solaris /usr/xpg4/bin/awk.
12178 The bug is present in at least Solaris 8 through 10.
12180 2005-08-24 Stepan Kasal <kasal@ucw.cz>
12182 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Simplify; rejecting
12183 some evil values and relying on the fact that $* concatenates the
12184 parameters by the first character from IFS.
12186 2005-08-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
12187 Stepan Kasal <kasal@ucw.cz>
12189 * lib/autoconf/status.m4 (_AC_CONFIG_REGISTER_DEST): When the
12190 first header appears, define AH_HEADER.
12191 * doc/autoconf.texi (Configuration Headers): Document AH_HEADER.
12192 Update limitations about when to call AC_CONFIG_HEADERS.
12193 (Configuration Commands): Document that AC_CONFIG_COMMANDS_PRE
12194 parameter can call AC_SUBST, AC_DEFINE, or AC_CONFIG_FOOS; explain
12195 that AC_CONFIG_COMMANDS_PRE and AC_CONFIG_COMMANDS_POST are not
12196 ``Configuration Actions''; fix their index entries.
12198 * lib/autotest/general.m4 (AT_INIT): Process multiple keywords
12199 options correctly. Process N-M as M-N if M is smaller than N.
12200 Process ranges correctly so that N-N will run only N.
12201 Sort and uniquify the tests that will be run. If there is more
12202 than one test, reinsert the banners for the tests.
12203 * tests/autotest.at (Keywords): Unmark XFAIL.
12205 2005-08-23 Stepan Kasal <kasal@ucw.cz>
12207 * lib/autoconf/general.m4 (_AC_DEFINE_Q): Strip the parameter list
12208 before passing the macro name to AH_TEMPLATE.
12210 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): config.status
12211 now opens log after option processing; in particular, --version
12212 and --help do not touch config.log.
12214 * Makefile.maint: Revert the change from 2005-08-12.
12216 2005-08-22 Stepan Kasal <kasal@ucw.cz>
12218 * lib/autoconf/general.m4 (AC_ARG_ENABLE, AC_ARG_WITH): Factor out
12220 (_AC_ENABLE_IF, _AC_ENABLE_IF_ACTION): ... these new macros.
12222 2005-08-21 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
12224 * doc/autoconf.texi (Using Autotest, testsuite Scripts)
12225 (Autotest Logs, Writing testsuite.at, testsuite Invocation):
12228 * doc/autoconf.texi (Defining Symbols, Changed Results):
12229 Prepend to LIBS, not append, in examples.
12231 2005-08-16 Stepan Kasal <kasal@ucw.cz>
12233 When building in place, set srcdir="."; suggested by Tim Van Holder.
12235 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Do this; to recognize
12236 build in place, we need ac_pwd, and thus have to AC_REQUIRE ...
12237 (_AC_INIT_DIRCHECK): ... this macro and AC_DEFUN both of them.
12238 * lib/autoconf/status.m4 (_AC_SRCDIRS): Fix a comment: srcdir="."
12239 does not mean "no --srcdir option".
12241 2005-08-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
12243 * tests/autoscan.at (autoscan): New file.
12244 * tests/suite.at: Use it.
12245 * tests/Makefile.am (TESTSUITE_HAND_AT): Add it.
12246 Reported against Libtool by Gideon Go <gideon.go@gmail.com>.
12248 * tests/autotest.at (Keywords): Test keywords combinations.
12250 2005-08-12 Stepan Kasal <kasal@ucw.cz>
12252 * Makefile.maint (GZIP_ENV): When checking the help text of gzip,
12253 add "2>&1"; gzip 1.2.4 prints help on stderr.
12255 2005-07-27 Stepan Kasal <kasal@ucw.cz>
12257 * lib/autotest/general.m4 (_AT_DECIDE_TRACEABLE): The symbol at_reason
12258 was pushdef'ed twice while popped only once. Push it only once.
12259 (_AT_CHECK): Cosmetic changes to the "case $at_status" command.
12261 2005-07-26 Stepan Kasal <kasal@ucw.cz>
12263 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): The message is now
12264 prefixed by mere "===", not "configure: === ".
12266 2005-07-25 Paul Eggert <eggert@cs.ucla.edu>
12268 * Makefile.maint: Update from Bison.
12270 * lib/m4sugar/m4sugar.m4 (m4_strip): Comment fix---change tab to
12271 "<tab>" in comment, so that the point is understandable.
12273 2005-07-25 Stepan Kasal <kasal@ucw.cz>
12275 Rewrite substantial part of lib/autoconf/status.m4.
12276 The main change is that CONFIG_FILES, CONFIG_HEADERS, CONFIG_LINKS,
12277 and CONFIG_COMMANDS are not processed in four separate loops.
12278 Instead, there is one main loop. This alows that the common code
12279 is expanded only once, thus config.status (and configure) is smaller.
12281 The registration mechnism in AC_CONFIG_FILES and cousins also changed;
12282 the AC_LIST_FILES and cousins macros are no longer used.
12284 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES, _AC_OUTPUT_HEADERS,
12285 _AC_OUTPUT_LINKS, _AC_OUTPUT_COMMANDS): Renamed to ...
12286 (_AC_OUTPUT_FILE, _AC_OUTPUT_HEADER, _AC_OUTPUT_LINK,
12287 _AC_OUTPUT_COMMAND): ..., respectively. These macros no longer
12288 contain the initialization, nor the for loop, nor the associated
12289 commands; all these go to ...
12290 (_AC_OUTPUT_MAIN_LOOP): ... this new macro, called from
12291 _AC_OUTPUT_CONFIG_STATUS.
12292 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST, _AC_CONFIG_SPLIT_FILE_IN):
12293 Nuked; the code was merged into _AC_OUTPUT_MAIN_LOOP.
12294 (_AC_OUTPUT_FILE): The creation of the sed script ...
12295 (AC_OUTPUT): ... and the setup of ac_vpsub goes to ...
12296 (_AC_OUTPUT_FILES_PREPARE): ... a new macro, also called from
12297 _AC_OUTPUT_MAIN_LOOP.
12298 (_AC_CONFIG_FILES, _AC_CONFIG_HEADERS, _AC_CONFIG_LINKS,
12299 _AC_CONFIG_COMMANDS): Use ...
12300 (_AC_CONFIG_FOOS): ... this new macro, which uses these ...
12301 (_AC_CONFIG_REGISTER, _AC_CONFIG_REGISTER_DEST): ... new macros.
12302 (_AC_CONFIG_FILE, _AC_CONFIG_HEADER, _AC_CONFIG_LINK,
12303 _AC_CONFIG_COMMAND, _AC_CONFIG_DEPENDENCIES): No longer needed.
12304 (_AC_CONFIG_DEPENDENCY): Update, it uses these ...
12305 (_AC_CONFIG_DEPENDENCY_DEFAULT, _AC_FILE_DEPENDENCY_TRACE_COLON):
12307 (_AC_CONFIG_UNIQUE): Update.
12308 (AC_LIST_FILES, AC_LIST_HEADERS, AC_LIST_LINKS, AC_LIST_COMMANDS):
12309 Replaced by this ...
12310 (_AC_LIST_TAGS): ... new common macro.
12311 (AC_LIST_FILE_COMMANDS, AC_LIST_HEADER_COMMANDS, AC_LIST_LINK_COMMANDS,
12312 AC_LIST_COMMAND_COMMANDS): Replaced by this ...
12313 (_AC_LIST_TAG_COMMANDS): ... new common macro.
12314 (_AC_CONFIG_COMMANDS_INIT): Moved top to the `registration' section;
12315 this didn't belong to the `config commands' section.
12316 (_AC_OUTPUT_COMMANDS_INIT): Don't initialize, m4_ifdef is our friend.
12317 (AC_CONFIG_COMMANDS_PRE, AC_OUTPUT_COMMANDS_PRE,
12318 AC_CONFIG_COMMANDS_POST): Moved to a new section, these didn't belong
12319 to the `config commands' section either.
12320 (AC_CONFIG_SUBDIRS): Don't touch diversion DEFAULTS.
12321 (_AC_LIST_SUBDIRS): Don't initialize, m4_ifdef is our friend.
12323 ... and many changes to the comments nearby.
12325 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): At the end of the day,
12326 set ac_subdirs_all='_AC_LIST_SUBDIRS'.
12327 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
12328 AC_CONFIG_COMMANDS(command:input,...) is no longer allowed.
12329 (#define header templates): The comment at the top of the generated
12330 header now includes the name(s) of the source file(s).
12332 Several unrelated small changes:
12334 * lib/autoconf/general.m4 (AC_CACHE_VAL): Be didactic, quote the first
12335 parameter to AC_DIAGNOSE.
12336 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS): Likewise.
12337 (_AC_LINK_FILES_CNT): Don't AU_DEFUN this; it causes confusing messages
12338 with autoupdate; use m4_define_default inside AU_DEFUNed AC_LINK_FILES.
12339 (AC_OUTPUT): In the compatibility code, use m4_ifvaln, to be consistent
12340 with AU::AC_OUTPUT.
12341 (AU::AC_OUTPUT): Don't double-quote $2 and $3, the compatibility code
12342 in AC_OUTPUT doesn't double-quote it either.
12343 * tests/tools.at (autoupdate): AU::AC_OUTPUT no longer double-quotes the
12346 2005-07-10 Stepan Kasal <kasal@ucw.cz>
12348 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Document which
12349 versions of Portland Group compiler produce single- and double-quoted
12350 -cmdline argument. Reported by Steven G. Johnson <stevenj@fftw.org>
12351 and Ole Holm Nielsen <Ole.H.Nielsen@fysik.dtu.dk>.
12353 2005-07-07 Paul Eggert <eggert@cs.ucla.edu>
12355 * tests/local.at (AT_CONFIG_CMP): Ignore lines like "LIBS=''" too.
12356 This is a corrected version of yesterday's patch.
12358 2005-07-07 Stepan Kasal <kasal@ucw.cz>
12360 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Report the full
12361 path, too; insert a "===" to emphasize the line.
12363 * lib/autoconf/general.m4 (AC_CANONICAL_BUILD): Rename
12364 ac_cv_build_alias to ac_build_alias.
12365 (AC_CANONICAL_HOST, AC_CANONICAL_TARGET): Simplify.
12367 On 2005-02-24, an unintentional AC_SUBST([CC]) was introduced; this
12368 change eliminates it. Problem reported by Alexandre Duret-Lutz.
12369 * lib/autoconf/general.m4 (_AC_ARG_VAR_PRECIOUS): Move the AC_SUBST ...
12370 (AC_ARG_VAR): ... here.
12371 (_AC_INIT_PREPARE): Call AC_SUBST for build_alias, host_alias and
12374 Keep a list of all precious variables and process them with one simple
12375 for loop, instead of expanding all commands, or, OTOH, complicated
12376 processing of output of "set".
12377 * lib/autoconf/general.m4 (_AC_ARG_VAR_PRECIOUS): Acumulate the
12378 variable names in new macro...
12379 (_AC_PRECIOUS_VARS): ... which will be assigned to ac_precious_vars.
12380 (_AC_ARG_VAR_STORE): New macro which writes to diversion PARSE_ARGS
12381 a loop to assign all ac_env_* and ac_cv_env_* variables.
12382 (_AC_ARG_VAR_VALIDATE): Use shell variable ac_precious_vars, divert
12384 (_AC_INIT_DEFAULTS): At the end, if _AC_PRECIOUS_VARS is set, assign
12385 its value to shell variable ac_precious_vars and call
12386 _AC_ARG_VAR_STORE and _AC_ARG_VAR_VALIDATE.
12387 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Don't call
12388 _AC_ARG_VAR_VALIDATE.
12390 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Move AC_LANG_PUSH(C)
12391 and the AC_SUBSTs ...
12392 (AC_INIT): ... here.
12394 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Changed the title of
12395 the ac_subst_files section in config.log.
12397 * tests/local.at (AT_CONFIG_CMP): Revert Paul's previous change.
12399 2005-07-06 Paul Eggert <eggert@cs.ucla.edu>
12401 * NEWS: New macro AC_C_TYPEOF.
12402 * doc/autoconf.texi (C Compiler): Document AC_C_TYPEOF.
12403 * lib/autoconf/c.m4 (AC_C_TYPEOF): New macro.
12404 * tests/c.at (C keywords): Test AC_C_TYPEOF.
12406 Fix problems reported by Nicolas Joly.
12407 * tests/base.at (Input/Output): Ignore 'loading site script' chatter.
12408 * tests/local.at (AT_CONFIG_CMP): Ignore lines like "LIBS=''" too.
12409 They are generated by the Tru64 v5.1B shell.
12411 2005-07-05 Stepan Kasal <kasal@ucw.cz>
12413 Fix my changes from 2005-07-01; reported by Noah Misch.
12414 * lib/autoconf/status.m4 (_AC_CONFIG_DEPENDENCIES): Fix the
12415 description, the macro now accepts only a single tag.
12416 (_AC_CONFIG_UNIQUE): Likewise; s/AC_File/[$1]/
12418 Fix cases when the varsions of Autoconf and Autotest don't match.
12419 Reported by Noah Misch.
12420 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Set also
12421 at_top_builddir, for compatibility with older autotest.
12422 * lib/autotest/general.m4 (AT_INIT): If at_top_build_prefix
12423 is not set, use at_top_builddir, for compatibility with older
12424 versions of autoconf.
12426 2005-07-04 Paul Eggert <eggert@cs.ucla.edu>
12428 * bin/autom4te.in ($m4): Catch usages like --nesting-limit=2048.
12429 Problem reported by Patrick Welche.
12431 2005-07-03 Paul Eggert <eggert@cs.ucla.edu>
12433 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Use &, not |, in
12434 sed substitution command, so that we allow | in program prefixes
12435 and program suffixes. (& is a problem anyway; we're not fixing
12437 * lib/autoconf/status.m4 (AC_CONFIG_FILES): Likewise, for
12438 configure_input, top_builddir, srcdir, etc.
12439 * lib/autotest/general.m4 (AT_INIT): Likewise, for
12440 PATH_SEPARATOR in AUTOTEST_PATH.
12442 2005-07-02 Alexandre Duret-Lutz <adl@gnu.org>
12444 * lib/autoconf/general.m4 (AC_SITE_LOAD): Rewrite the
12445 for loop over config.site files using `set', to allow
12446 directory names containing IFS characters.
12448 2005-07-01 Paul Eggert <eggert@cs.ucla.edu>
12450 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Remove the tests for
12451 directories with weird names. Apparently some people like living
12452 on the edge. However, improve the test that "pwd" actually does
12453 report a name for the working directory.
12454 * NEWS: Remove the claim that we test for funny chars in dir names.
12456 2005-07-01 Stepan Kasal <kasal@ucw.cz>
12458 * lib/autoconf/general.m4 (AC_FOREACH): Make obsolete; it's
12460 * lib/m4sugar/m4sugar.m4 (m4_foreach_w): ... by this new macro.
12461 * lib/autoconf/status.m4 (_AC_CONFIG_DEPENDENCIES, _AC_CONFIG_UNIQUE):
12462 Now accept a single tag, not whitespace separated list.
12463 (AC_CONFIG_SUBDIRS): Call _AC_CONFIG_UNIQUE in a m4_foreach_w loop.
12465 2005-06-30 Stepan Kasal <kasal@ucw.cz>
12467 * doc/autoconf.texi (Configuration Headers): Change the explanation
12468 about #include <config.h>.
12469 (Generic Functions): Mention the Gnulib project.
12470 (Limitations of Usual Tools) <sed>: Another minor rephrasing.
12472 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Use a here
12473 document to output the default config_* lists to config.status.
12474 Don't recognize option --file, if the functionality is not there.
12475 Likewise for --header; moreover, recognize --he and --h as shortcuts
12476 for --help in that case.
12478 * lib/autoconf/status.m4: Fix the order of the "sections", so that it
12479 matches the order of execution. No code changed.

12501 instead of AC_SUBST; proposed by Alexandre Duret-Lutz.
12502 (AC_SUBST): Call it.
12503 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Call AC_SUBST_TRACE for
12504 the directory specific variables; but don't call it for configure_input.
12506 2005-06-28 Derek Price <derek@ximbiot.com>
12508 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: Reword recent
12511 2005-06-23 Paul Eggert <eggert@cs.ucla.edu>
12513 * NEWS: Don't worry about spaces in bindir etc. Only srcdir and working
12514 directory have inherent problems with special characters like spaces,
12515 due to limitations in Make syntax. Problem reported by Alexandre
12517 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Implement the above.
12518 Also, fix Tru64 porting problem with shell patterns,

12529 Fix some more shell quoting problems. Prompted by a bug report
12530 from Justace Clutter.
12531 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Put name of invalid
12532 variable into diagnostic. Make the diagnostic an error, not a warning,
12533 because we really don't support spaces and suchlike in dir names.
12534 (_AC_INIT_SRCDIR): Allow special characters in $ac_unique_file.
12535 Don't worry about backslashes in srcdir; it can't happen now.

12546 (AT_CONFIG_CMP): Use sed instead of grep plumbing.
12548 * doc/autoconf.texi (Limitations of Usual Tools) <grep>: Mention
12549 that '\|' is not allowed in BREs; recommend using newline separated
12550 list of patterns instead of multiple -e options.

12560 2005-06-21 Stepan Kasal <kasal@ucw.cz>
12562 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: Document that
12563 b, t, r, w commands require single space, while : cannot have any.
12564 (Special Shell Variables): Fix sed code this in the example.
12565 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Likewise; and fix a typo.
12566 * lib/autotest/general.m4 (AT_ARG_OPTION): Fix typo in the description.
12568 * lib/m4sugar/m4sugar.m4 (m4_split): If the parameter is empty,
12569 expand to the empty list. Don't use two pairs of m4_changequote,
12570 it's not necessary.
12572 2005-06-20 Derek Price <derek@ximbiot.com>
12574 * lib/m4/programs.m4 (AC_PROG_YACC): Declare YACC & YFLAGS precious.
12576 2005-06-17 Paul Eggert <eggert@cs.ucla.edu>
12578 * lib/m4sugar/m4sh.m4 (as_awk_strverscmp): Port to Solaris /bin/awk.
12579 * doc/autoconf.texi:
12580 Don't mention Solaris versions so much, if a
12581 problem is common to all extant versions of Solaris. Say "SunOS
12582 4" instead of "SunOS" for SunOS 4.
12583 (awk): Mention more of the limitations of traditional Awk.
12584 (cat): Don't talk about cat -v.
12586 2005-06-16 Paul Eggert <eggert@cs.ucla.edu>
12588 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE): New macro.
12589 (AS_VERSION_COMPARE): New macro. The API is taken from CVS,

12591 to be compatible with glibc strverscmp.
12592 * tests/m4sh.at (AS_VERSION_COMPARE): New test.
12594 * doc/autoconf.texi (Limitations of Usual Tools): Mention expr bug

12597 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT):
12598 Use shell builtins rather than 'expr', to work around expr bug.
12600 2005-06-10 Paul Eggert <eggert@cs.ucla.edu>
12602 * doc/autoconf.texi: "filesystem" -> "file system".
12603 "behaviour" -> "behavior".
12604 Warn about \(...\)* in Solaris sed (written by Ralf Menzel).
12605 * lib/autoconf/general.m4: Omit blank after ":" sed command,
12607 * lib/m4sugar/m4sh.m4: Likewise.

12612 (.x.1): Ignore the time stamp in the .TH line when deciding whether
12613 to update the man page. That way, we don't have to check in new
12614 man pages every month.
12616 * lib/m4sugar/m4sh.m4 (AS_VAR_TEST_SET): Work even if $1 contains
12617 quotes and backslashes. Patch from Derek Price.

12626 * lib/autotest/general.m4 (AT_INIT): Don't accept Solaris 9's diff
12627 -u, since it outputs chatter if the input files are the same.
12628 Problem reported by Ralf Menzel.
12630 2005-06-08 Derek Price <derek@ximbiot.com>
12632 * lib/m4sugar/m4sugar.m4: Undefine include & sinclude rather than
12633 renaming them since they are about to be redefined anyhow.
12635 2005-06-08 Derek Price <derek@ximbiot.com>
12637 * doc/autoconf.texi (Redefined M4 Macros): Add index entries for most
12638 redefined M4 macros to this node. Document m4_include & m4_sinclude.
12639 Move m4_undefine to alphabetical order.
12641 2005-06-07 Paul Eggert <eggert@cs.ucla.edu>
12643 * README: Recommend GNU M4 1.4.3 or later.
12644 * doc/autoconf.texi (Introduction): Likewise.
12645 Reword to avoid some formatting glitches.
12646 Use "#!/bin/sh", not "#! /bin/sh"; the space isn't needed these days.
12647 Clarify explanation of HP compiler bug.
12648 Redo example output tp match current CVS snapshot.
12649 Use @example.org in email addresses when the examples
12650 might get inadvertently cut-and-pasted into user code.
12651 Remove example of autom4te usage that doesn't seem to work now.
12652 Use modern AC_INIT (except when the example is meant to be
12653 shown with Autoconf 2.13).
12654 Update ksh info for Solaris 9 and later.
12656 Modernize description of Automake versions a bit.
12657 Don't claim a future version of Autoconf is near.
12658 * doc/install.texi: Reword to avoid some formatting glitches.
12660 2005-06-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
12662 * doc/autoconf.texi: Add [] to examples, so that the manual
12663 follows its own advice about quoting better.
12664 Reword to avoid some formatting glitches.
12665 * doc/installt.exi: Reword to avoid some formatting glitches.
12667 * doc/autoconf.texi (Limitations of Builtins) <case>: Mention
12668 Tru64 ksh pattern matching bug. Reported against Libtool by
12669 Albert Chin <libtool@mlists.thewrittenword.com> and
12670 Nicolas Joly <njoly@pasteur.fr>.
12672 2005-06-06 Stepan Kasal <kasal@ucw.cz>
12674 m4_cdr of one-member list was [[]] (one-member list containing an
12675 empty string) instead of [] (an empty list. Callers were skewed to
12676 match this misbehaviour. As a consequence of this:
12677 - m4_foreach([x], [], [foo]) expanded to `foo', while
12678 - the expansion of m4_foreach([x], [[]], [foo]) was empty.
12679 This bug has been fixed:
12681 * lib/m4sugar/m4sugar.m4 (m4_cdr): If only one argument is given,
12682 expand to an empty string; print error msg if called without
12684 (m4_foreach, m4_map, m4_map_sep): Don't expect the previous
12685 misbehaviour; handle [] and [[]] correctly.
12687 2005-06-06 Stepan Kasal <kasal@ucw.cz>
12689 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Nuke ac_max_here_lines.
12690 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Simplify the sed
12691 scripts created and the loop applying them, use _AC_SED_CMD_LIMIT.
12693 2005-06-06 Ralf Menzel <menzel@ls6.cs.uni-dortmund.de> (trivial change)
12695 * doc/autoconf.texi (Limitations of Usual Tools): Solaris' awk cannot
12696 swallow records with more than 99 fields.
12697 * lib/autotest/general.m4 (AT_INIT): Use the awk builtin `split' to
12698 parse the long line.
12700 2005-06-04 Stepan Kasal <kasal@ucw.cz>
12702 * doc/autoconf.texi (Limitations of Usual Tools): AIX awk cannot
12703 swallow literals longer than 399. Reported by Ralf Wildenhues.
12704 * lib/autotest/general.m4 (AT_INIT): Pass $at_groups though stdin,
12705 to workaround this limitation.
12707 2005-06-03 Steven G. Johnson <stevenj@alum.mit.edu>
12709 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Find g95 in addition
12710 to gfortran, and make these the first two compiler names
12711 checked (following the general autoconf preference for gcc).
12713 2005-06-03 Stepan Kasal <kasal@ucw.cz>
12715 * tests/Makefile.am (check_SCRIPTS): Set to $(wrappers).
12716 (DISTCLEANFILES): Remove $(check_SCRIPTS).
12717 (testsuite): Make sure autotest.m4f is up-to-date before using it.
12719 2005-06-02 Paul Eggert <eggert@cs.ucla.edu>
12721 * lib/autotest/general.m4 (AT_INIT): Don't create a regular
12722 expression of unbounded size when processing the --list
12723 option. This runs afoul of a limit of 399 bytes per regular
12724 expression on AIX. Problem reported by Ralf Wildenhues.
12726 2005-06-01 Paul Eggert <eggert@cs.ucla.edu>

12729 * doc/autoconf.texi (Particular Headers): Reword example
12730 for multiline stdbool replacement.
12731 (Setting Output Variables): Reword text a bit. Don't
12732 give all the details about |#_!!_#|.
12733 Reword description of line replacement.
12735 2005-05-31 Dan Manthey <dan_manthey@partech.com>
12737 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Output variables may
12738 now contain newlines, and substituted files must be referenced on
12739 a line alone; the sed scripts to substitute them are now very
12741 (_AC_SED_CMD_LIMIT): Added; single place to store limit on how many
12742 commands can be put in a sed script portably.
12743 * doc/autoconf.texi (Setting Output Variables): Document above
12744 changes. (Particular Header Checks) <AC_HEADER_STDBOOL>: Give exaple
12745 use of multiline substitution.

12755 * tests/local.at: Don't attempt to check for negated character
12756 classes in shell scripts. The test was too brittle.
12758 2005-05-25 Stepan Kasal <kasal@ucw.cz>
12760 * bin/autoconf.as: Don't use "shift 2"; it's not portable enough.
12761 * doc/autoconf.texi (Limitations of Builtins): Document this
12764 2005-05-24 Stepan Kasal <kasal@ucw.cz>
12766 * lib/m4sugar/m4sh.m4 (_AS_ECHO_LOG): New macro to factor out
12767 common code; used in many places in the tree.

12771 * lib/m4sugar/m4sugar.m4 (m4_ifset): Use m4_ifval.
12773 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Merge the two error
12774 messages when ac_unique_file is not found.
12775 (AC_CONFIG_MACRO_DIR): Simplify the `if' at the end.
12776 (AC_MSG_CHECKING, AC_MSG_RESULT): Put braces around the two echo
12777 commands, for consistency with AC_MSG_ERROR and such.
12779 * bin/autoconf.as: Make more use of "shift 2" in option processing.
12781 * bin/Makefile.am: Merge the two rules for creating scripts.

12789 2005-05-20 Stepan Kasal <kasal@ucw.cz>
12791 * NEWS: @top_builddir@ is now a dirname, ac_top_builddir will follow.
12792 * lib/autoconf/status.m4 (_AC_SRCDIRS): Rename ...
12793 (ac_top_builddir): ... this ...
12794 (ac_top_build_prefix): ... to this; the old name is also kept, for
12795 backward compatibility.
12796 (ac_top_builddir_sub): New variable, without the trailing slash,
12798 (_AC_OUTPUT_FILES): s/@top_builddir@/$ac_top_builddir_sub/
12799 * doc/autoconf.texi (Configuration Actions): Rename
12800 ac_top_builddir to ac_top_build_prefix.

12812 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Don't m4_quote the second
12813 argument to m4_foreach. I guess it was necessary in the past,
12814 but I think it's a no-op now.
12816 2005-05-17 Stepan Kasal <kasal@ucw.cz>
12818 * lib/autoconf/general.m4 (_AC_INIT_HELP): Merge two consecutive
12819 ``cat <<_ACEOF'' commands to one.
12820 (_AC_CANONICAL_SPLIT): Use expr, not ``echo|sed.''
12821 * lib/autoconf/status.m4: On various places, use expr instead of
12823 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST):
12824 (_AC_CONFIG_SPLIT_FILE_IN): New macros, to factor out common code.
12825 * lib/autotest/general.m4 (AT_INIT): Use expr to get the numbers from
12827 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Use awk to search for
12828 the wrong patterns between ``case'' and ``esac.'' The previous
12829 code had false positives.

12897 * doc/autoconf.texi (Autoconf Language): Be more precise about
12898 quoting rules. Problems noted by Stepan Kasal.
12899 Also, throughout this document, be more careful about white space.
12900 "blank", "white space", and "space" all have different meanings
12901 and we should be careful to say what we mean.
12903 2005-05-05 Paul Eggert <eggert@cs.ucla.edu>
12905 Fix C++ related problems reported by Werner Lemberg.
12906 * doc/autoconf.texi (C++ Compiler): Mention .cpp extension.

12937 * lib/autotest/general.m4 (AT_KEYWORDS): Separate by space,
12940 * doc/autoconf.texi (External Software): Replace AC_DEFINE_UNQUOTED
12941 by AC_DEFINE; it was a mistake.
12942 From bug reported against libtool by Dalibor Topic <robilad@kaffe.org>.
12944 2005-04-25 Stepan Kasal <kasal@ucw.cz>

12948 2005-04-22 Stepan Kasal <kasal@ucw.cz>
12950 * doc/autoconf.texi (External Software): Quadrigraphs are not
12951 processed correctly in AS_HELP_STRING; avoid this in the examples.
12952 * lib/m4sugar/m4sh.m4 (AS_HELP_STRING): Add a FIXME about quadrigraphs.
12953 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Likewise; and rephrase the

12959 * lib/autoconf/general.m4 (_AC_INIT_PREPARE, _AC_RUN_IFELSE):
12960 Remove core.conftest.* too; it's generated by Tru64 5.1.
12961 Problem reported by Jennis Pruett.
12962 * lib/autoconf/functions.m4
12963 (AC_FUNC_SETVBUF_REVERSED, AC_FUNC_UTIME_NULL):

13011 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS):
13012 Merge `-z option' as well for the benefit of Solaris link flags. Pass

13014 unique libraries, for the Sun Fortran 95 8.0 compiler. Bug reported
13015 against Libtool by Yury Puhalsky <pooh@cryptopro.ru>.

13019 * NEWS: The configure command now warns you if you attempt to use
13020 a directory whose name contains a special character like space,
13022 * doc/autoconf.texi (Installation Directory Variables): Allow

13036 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Propagate
13037 ac_pwd, and quote srcdir.
13038 * lib/autotest/general.m4 (AT_INIT): Quote file name args.
13040 * doc/autoconf.texi: Fix some systematic formatting problems.
13041 ".)" needs a following @: if not at the end of a sentence, and
13042 similarly for "!)". "etc." should be preceded by a comma.
13043 "n-th" -> "@var{n}th". pdksh is still buggy, so update its date.
13045 2005-03-22 Bruno Haible <bruno@clisp.org>
13047 * doc/autoconf.texi (Input): Mention that AC_CONFIG_AUX_DIR's
13048 argument is often called 'build-aux'.
13050 2005-03-07 Stepan Kasal <kasal@ucw.cz>
13052 * doc/autoconf.texi (Quotation Rule Of Thumb): Mention that the
13053 macro AC_TRY_LINK is obsolete.

13057 2005-02-24 Stepan Kasal <kasal@ucw.cz>
13059 * lib/autoconf/c.m4 (AC_PROG_CC): Be more careful to skip
13060 `/usr/ucb/cc'; use `cl.exe' to distinguish the MS compiler
13061 from a Common Lisp's `cl'.
13062 (AC_PROG_CXX): Behave according to the documentation: don't
13063 search for $ac_tool_prefix$CCC and $CCC, just set CXX=$CCC;
13064 make the variable CCC precious; use `cl.exe', not `cl'.
13066 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
13067 Alexandre Duret-Lutz <adl@gnu.org>
13069 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin from
13070 /dev/null, as "configure" shouldn't read stdin, and this insulates
13071 us from problems (e.g., when testing for "cl"). Also, do this
13072 redirection before invoking "hostname" or "uname", and keep the
13073 original input stream available via...
13074 (AS_ORIGINAL_STDIN_FD): ... this new macro.
13075 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't

13085 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
13087 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N_PREPARE): Don't set ECHO_C to
13088 newline if neither \c nor -n work, as that would output two
13089 newlines. Prefer -n to \c. Reported by Stepan Kasal.
13091 2005-02-12 Stepan Kasal <kasal@ucw.cz>
13093 * lib/m4sugar/m4sh.m4 (AS_IF): Define by m4_defun, not m4_define.
13094 This causes that any required macros inside will get before the if.
13095 * doc/autoconf.texi (autom4te.cache): A typo.
13097 2005-02-12 Paul Eggert <eggert@cs.ucla.edu>
13099 Undo previous change, except keep the change to
13100 lib/autoconf/programs.m4 that replaced grep with shell
13101 pattern-matching. This is because net-snmp configure reads stdin.
13102 Reported by Noah Misch.
13104 2005-02-11 Paul Eggert <eggert@cs.ucla.edu>
13106 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin
13107 from /dev/null, as "configure" shouldn't read stdin, and this
13108 insulates us from problems (e.g., when testing for "cl").
13109 Suggested by Alexandre Duret-Lutz. Also, do this redirection
13110 before invoking "hostname" or "uname".
13111 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
13112 _AC_LINK_IFELSE): Undo previous change, as it's no longer needed.
13113 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Don't bother with
13114 "</dev/null" since it's now done at the top of 'configure'.
13115 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
13116 * lib/autoconf/programs.m4 (_AC_PATH_PROG_FLAVOR_GNU): Likewise.
13117 Also, replace grep with shell pattern-matching, to save a process.
13119 2005-02-10 Paul Eggert <eggert@cs.ucla.edu>
13121 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
13122 _AC_LINK_IFELSE): Redirect stdin to /dev/null, in an attempt to
13123 avoid thinking that Allegro Common Lisp's "cl" command is a C++
13126 2005-02-09 Paul Eggert <eggert@cs.ucla.edu>
13128 * doc/autoconf.texi (Limitations of Usual Tools): Document that
13129 grep -q isn't portable. Improve grep -s explanation.
13130 Problem reported by Dan Manthey.
13132 2005-02-08 Paul Eggert <eggert@cs.ucla.edu>
13134 * doc/autoconf.texi (Special Shell Variables): Clarify

13137 2005-02-07 Paul Eggert <eggert@cs.ucla.edu>
13139 * doc/autoconf.texi: Use @acronym for DJGPP.
13140 Fix some @code's that should have been @env's, and vice versa.
13141 Sort environment variable names.
13142 Mention that shells no longer inherit IFS.
13143 Don't recommend PATH_SEPARATOR=';' so strongly.
13144 Mention that $RANDOM might expand to the empty string.
13145 "symlink" and "soft link" -> "symbolic link".
13146 Improve mktemp description (reported by Bruno Haible).

13222 this fixes a bug tickled by the AT_CAPTURE_FILE change noted below.

13285 Simplify the implementation of m4_require (a.k.a. AC_REQUIRE).
13286 Update the long comment explaining it.
13288 m4_require no longer writes an ``is required by'' line to the
13289 execution stack. It contains only one bit of non-redundant
13290 information: that the macro was required, not called. And even
13291 this bit is useless in most situations: have you ever met a macro
13292 which both calls and requires the same macro?
13294 * lib/m4sugar/m4sugar.m4 (_m4_defun_pro): Don't push a diversion...
13295 (_m4_defun_pro_outer): ... only via this macro, for the outermost

13298 (m4_expansion_stack_pop): Remove the misplaced comment.
13299 (m4_require): Don't put the ``is required by'' line to the
13300 execution stack; slightly improve the out-of-a-defun error message.
13301 (_m4_divert_grow): New macro, counter for the temporary diversions.
13302 (_m4_require_call): Use it.
13303 * tests/m4sugar.at (m4_require): Expect output without the

13340 2005-01-20 Paul Eggert <eggert@cs.ucla.edu>
13342 * doc/autoconf.texi (Shell Substitutions): Fix typo in case statement.
13343 Warn about newline stripping in `` and $(). Update Solaris
13345 (Limitations of Builtins): Use expr "X...", not expr "x...", as

13714 * lib/autoconf/functions.m4 (AC_FUNC_MEMCMP): Use
13715 "char c = '\200';" rather than "char c = 0x80;" as the

13833 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): If xmkmf returns
13834 "/usr/include", clear ac_x_includes instead of leaving it as "no"
13835 (trivial change). Problem and patch reported by Andrew Church in:

13866 texinfo.tex for now (done by hand now).
13867 * Makefile.maint (wget_files, cvs_files):
13868 Remove ansi2knr.c; nobody uses it.
13869 (ansi2knr.c-url_prefix): Remove.
13870 (cvs-update): Fix test for failure. I don't know why it ever
13873 * doc/autoconf.texi: Update URLs, some of which went stale.
13874 Use @uref rather than @href.
13876 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Have configure
13877 handle "--" as per POSIX. Suggested by Paul Pogonyshev.
13879 * config/config.guess, config/config.sub, config/elisp-comp,
13880 config/install-sh, config/mkinstalldirs, config/texinfo.tex,
13881 doc/fdl.texi, doc/standards.texi: Sync with master copy.
13883 * NEWS, TODO, configure.ac, bin/autoscan.in,
13884 bin/autoupdate.in, bin/ifnames.in, doc/autoconf.texi,

13890 tests/tools.at, tests/torture.at:
13891 Use "file name" rather than "filename" or "path",
13892 to be consistent with the terminology of the GNU coding standards.
13894 2004-08-19 Paul Eggert <eggert@cs.ucla.edu>
13896 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C),
13897 AC_C_LONG_DOUBLE): Undo 2004-06-04 change, as it didn't work with
13898 HP-UX 11.23 cc/aCC or Tru64 4.0 cc. Problem reported by Noah Misch in
13899 <http://lists.gnu.org/archive/html/autoconf/2004-07/msg00004.html>.
13901 More fixes to support spaces in the name of the build directory.
13902 This isn't a complete fix but it's an improvement.
13904 * bin/autoconf.as (autom4te_options): New var.
13905 Use it instead of appending to AUTOM4TE, so that we can allow
13906 spaces in the build directory's absolute name.
13907 * bin/autoheader.in ($autoconf): Allow spaces in file names.
13908 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP, _AT_CHECK,
13909 AT_CHECK_NOESCAPE): Likewise.
13910 * tests/wrapper.as (testdir, AUTOM4TE_CFG, autom4te_perllibdir,

13921 * doc/autoconf.texi (Function Portability): Document isinf and
13922 and isnan. From a suggestion by Kevin Ryde.
13924 * lib/Autom4te/General.pm (END): Return correct exit status even
13925 if unlink succeeds and sets $?. Needed with Solaris 8's perl 5.00503.
13927 2004-08-09 Paul Eggert <eggert@cs.ucla.edu>
13929 * tests/torture.at (Deep Package): Use configure.in, not configure.ac,
13930 for compatibility with Automake 1.4. Reported by J C Fitzgerald in
13931 <http://lists.gnu.org/archive/html/bug-autoconf/2003-08/msg00051.html>.
13933 2004-08-04 Alexandre Duret-Lutz <adl@gnu.org>
13935 * lib/autoconf/general.m4 (AC_REQUIRE_AUX_FILE): New empty macro.
13936 (AC_CANONICAL_BUILD): Call it to require config.sub and config.guess.
13937 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Likewise for install-sh.
13938 * doc/autoconf.texi (Input): Document AC_REQUIRE_AUX_FILE.
13939 * lib/autom4te.in (Automake-preselections): Preselect
13940 AC_REQUIRE_AUX_FILE. Automake 1.10 will trace it.
13942 2004-08-02 Alexandre Duret-Lutz <adl@gnu.org>
13944 * lib/autom4te.in (Automake-preselections): Preselect
13945 AC_CANONICAL_BUILD and AC_CANONICAL_TARGET. Automake 1.9.1 will
13948 2004-07-29 Paul Eggert <eggert@cs.ucla.edu>
13950 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): Set BIN_SH, for
13952 * doc/autoconf.texi (Shellology): Mention BIN_SH.
13953 Document problem with "`""`" in pdksh POSIX mode.
13955 2004-07-27 Paul Eggert <eggert@cs.ucla.edu>
13957 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): Use "set -o posix"
13958 with pdksh, too. Problem reported by Patrick Welche via
13960 * doc/autoconf.texi (Shellology): Note that set -o posix is
13961 useful for pkdsh, too.
13963 2004-06-24 Paul Eggert <eggert@cs.ucla.edu>
13965 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Require
13966 _AS_UNSET_PREPARE, so that we can use $as_unset directly.
13967 Don't fail if ENV or BASH_ENV is readonly.
13968 (AS_SHELL_SANITIZE): Don't fail if ENV, MAIL, MAILPATH, LC_ALL,
13969 etc. are read only. Problem reported by Ludovic Courtes.
13971 2004-06-23 Noah Misch <noah@cs.caltech.edu>
13973 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): If the shell is
13974 zsh, disable GLOB_SUBST to avoid backslash handling problems.
13977 2004-06-04 Paul Eggert <eggert@cs.ucla.edu>
13979 * doc/autoconf.texi (File System Conventions): Warn about
13980 names like "aux". Problem reported by Eric Blake.
13982 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY (C)): Use division
13983 by zero instead of array size, so that we can use any arithmetic
13984 constant expression (instead of requiring an integer constant
13985 expression). This allows us to test expressions like DBL_MAX <
13986 LDBL_MAX, which didn't conform to the C standard using the old
13988 (AC_C_LONG_DOUBLE): Put back in the tests for LDBL_MAX and LDBL_EPSILON,
13989 now that we can do floating-point tests at compile time.
13991 2004-06-02 Paul Eggert <eggert@cs.ucla.edu>
13993 * lib/autoconf/c.m4 (AC_C_LONG_DOUBLE): Don't check LDBL_MAX
13994 and LDBL_EPSILON, as the resulting expression isn't an
13995 integer constant expression and violates the C standard.
13996 Problem reported by Nelson H. F. Beebe. Also, check
13997 for "L" suffix, and check that long double doesn't have
13998 worse range or precision than double, that mixed-mode
13999 arithmetic doesn't generate a diagnostic, that double
14000 constants fit in long double.
14002 2004-06-03 Kevin Ryde <user42@zip.com.au>
14004 * doc/autoconf.texi (Function Portability): Add notes on free(NULL),
14005 malloc(0) and realloc(NULL,size).
14007 * doc/autoconf.texi (Shell Substitutions): Spelling error reported by
14010 2004-05-31 Paul Eggert <eggert@cs.ucla.edu>
14012 * lib/autoconf/headers.m4 (HAVE_STDBOOL_H): Detect _Bool bug
14013 in HP aC++/ANSI C B3910B A.05.55 [Dec 04 2003]. Problem reported
14016 2004-05-26 Paul Eggert <eggert@cs.ucla.edu>
14018 * doc/autoconf.texi (Limitations of Builtins): Mention that ! COMMAND
14019 can be rewritten using if-then-else. Suggested by Bruno Haible.
14021 2004-05-25 Paul Eggert <eggert@cs.ucla.edu>
14023 * doc/autoconf.texi (testsuite Scripts): Fix typo.
14024 Problem reported by Stepan Kasal.
14026 2004-05-24 Paul Eggert <eggert@cs.ucla.edu>
14028 * tests/Makefile.am (autoconfdir): Fix to match comment (trivial
14029 change). Patch reported by Ralf Wildenhues in
14030 <http://mail.gnu.org/archive/html/bug-autoconf/2004-05/msg00092.html>.
14032 * lib/autoconf/functions.m4 (AC_FUNC_MBRTOWC): Don't assume that a
14033 function F exists if the compiler and linker let you compile an
14034 expression like (F != 0). Recent versions of GCC optimize away
14035 the reference to F in that case, since every function address must
14036 be nonzero, so the link succeeds even if F does not exist.
14037 Problem reported by Manu in
14038 <http://mail.gnu.org/archive/html/bug-gnu-utils/2004-05/msg00060.html>.
14040 * doc/autoconf.texi (Systemology): Standardize on the spelling of
14041 "Unix". Many uses changed.
14042 (Limitations of Builtins): Explain better why the ! command isn't
14045 2004-05-22 Alexandre Duret-Lutz <adl@gnu.org>
14047 * lib/autom4te.in (Automake-preselections): Preselect
14048 LT_SUPPORTED_TAG in lieu of AC_LIBTOOL_TAGS.
14050 2004-05-19 Kevin Ryde <user42@zip.com.au>
14052 * doc/autoconf.texi (Function Portability): Add strerror_r, cross
14053 referencing AC_FUNC_STRERROR_R.
14055 * doc/autoconf.texi (Particular Functions): In AC_FUNC_CLOSEDIR_VOID,
14056 note pessimistic assumption when cross compiling.
14058 2004-05-16 Paul Eggert <eggert@cs.ucla.edu>
14060 * doc/autoconf.texi (Limitations of Make): Note that BSD make
14061 (until 2004) invoked subcommands with sh -e, contra POSIX.
14062 Reported by Kevin Ryde.
14064 2004-05-10 Eric Sunshine <sunshine@sunshineco.com>
14066 * programs.m4 (_AC_PROG_GREP): Fixed bug where PATH argument handed to
14067 _AC_PATH_PROG_FEATURE_CHECK contained leading whitespace (i.e.
14068 " $PATH:/usr/xpg4/bin"). This resulted in bogus tests, such as
14069 `test -f " /usr/bin/grep"', which _always_ failed.
14070 (AC_PROG_SED): Ditto bogus PATH fix.
14071 * autoconf.texi (AC_PROG_GREP): Properly document that this macro
14072 requires that grep correctly supports _multiple_ `-e' options, rather
14073 than stating only that grep should accept `-e'.
14075 2004-05-03 Paul Eggert <eggert@cs.ucla.edu>
14077 Port to C99, which requires that 'exit' be declared.
14079 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Use AC_INCLUDES_DEFAULT
14080 to ensure that stdlib.h is included.
14081 * lib/autoconf/functions.m4 (_AC_LIBOBJ_ALLOCA, AC_FUNC_SETPGRP,
14082 AC_FUNC_STRTOD, AC_FUNC_SETVBUF_REVERSED, AC_FUNC_FORK, _AC_FUNC_FORK,
14083 _AC_FUNC_VFORK, AC_FUNC_WAIT3): Likewise.
14084 * lib/autoconf/specific.m4 (AC_SYS_RESTARTABLE_SYSCALLS): Likewise.
14085 * lib/autoconf/types.m4 (AC_TYPE_GETGROUPS): Likewise.
14086 * lib/autoconf/headers.m4 (AC_HEADER_STDC): Include <stdlib.h>
14087 when using 'exit' in a test; C99 requires that 'exit' be declared.
14089 2004-05-02 Paul Eggert <eggert@cs.ucla.edu>
14091 * doc/autoconf.texi (Particular Programs): AC_PROG_GREP
14092 now prefers 'grep' implementations that accept -e.
14093 (Limitations of Usual Tools): Describe problems of traditional
14094 egrep and fgrep with long input lines, and of traditional grep
14096 * lib/autoconf/programs.m4 (AC_PROG_GREP): Check for -e, too.
14097 (_AC_PROG_GREP): Assume 3rd arg is properly quoted for the shell.
14098 All callers changed. Append /usr/xpg4/bin to the PATH, for
14100 (_AC_FEATURE_CHECK_LENGTH): Discard stderr, so we don't bother
14101 the user with complaints about multiple -e options.
14102 * tests/local.at (AC_STATE_SAVE): Use $GREP, not grep.
14103 Define it with AC_PROG_GREP.
14104 * configure.ac (AC_PROG_GREP): Add.
14105 * lib/freeze.mk (GREP): New macro.
14107 2004-05-02 Eric Sunshine <sunshine@sunshineco.com>
14109 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Consult $SHELL as
14110 a possible candidate only after all others fail, rather than
14111 consulting it first. This improves backward compatibility by
14112 better reflecting the way shell selection occurred in previous
14113 versions of Autoconf, and should help to avoid triggering latent
14114 problems in other packages, such as the one in Automake where zsh
14115 is not handled robustly:
14116 http://mail.gnu.org/archive/html/automake/2004-04/msg00095.html
14117 Although it is not Autoconf's responsibility to work around
14118 problems in Automake, it nevertheless makes sense to avoid
14119 introducing unnecessary incompatibilites.
14121 2004-04-22 Albert Chin-A-Young <china@thewrittenword.com>,
14122 Gary V. Vaughan <gary@gnu.org>
14124 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Don't guess
14125 how deeply nested we are when a suitable tool is found, set the
14126 ac_path_TOOL_found flag.
14127 (_AC_PATH_PROG_FEATURE_CHECK): Encapsulate knowledge of how deeply
14128 nested we are in this macro. Break out of all 3 nested loops if
14129 ac_path_TOOL_found is set.
14131 2004-04-21 Gary V. Vaughan <gary@gnu.org>
14133 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Break out
14134 of the _AS_PATH_WALK loop too if GNU flavor is found.
14136 2004-04-21 Alexandre Duret-Lutz <adl@gnu.org>
14138 * doc/autoconf.texi (Limitations of Make): Update documentation
14139 for `$<'. New entry `Long lines', based on a report from Simon
14140 Josefsson. Augment the documentation for SHELL = @SHELL@ with a
14141 paragraph about DJGPP, based on a mail from Richard Dawe.
14143 2004-04-20 Paul Eggert <eggert@twinsun.com>
14145 * tests/c.at (C keywords): Don't assume that GCC supports
14146 "restrict" and "inline", as sufficiently-old GCC versions do not
14147 (also, GCC configured to be in pedantic C89 mode does not).
14148 Problem reported by Sumit Pandya in:
14149 http://mail.gnu.org/archive/html/autoconf/2004-04/msg00092.html
14151 * lib/autoconf/c.m4 (_AC_PROG_CC_G, _AC_PROG_CXX_G): Don't
14152 consider -g to work if it generates warnings when plain compiles
14153 don't. Problem reported by Braden McDaniel in:
14154 http://mail.gnu.org/archive/html/autoconf-patches/2003-07/msg00014.html
14156 * doc/autoconf.texi (Slashes): New section, to document a problem
14157 reported by Jim Meyering in:
14158 http://mail.gnu.org/archive/html/bug-coreutils/2004-02/msg00060.html
14160 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Remove potential
14161 linker output files before linking, to work around IRIX 6 linker bug.
14162 Problem reported by Rainer Orth in:
14163 http://mail.gnu.org/archive/html/autoconf-patches/2004-02/msg00007.html
14165 2004-04-20 Gary V. Vaughan <gary@gnu.org>
14167 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Make the
14168 best tool so far counter rely on the tool path variable name to
14169 avoid checks for one tool being affected by the results of running
14170 the length check on a previous tool.
14172 * lib/autoconf/programs.m4 (_AC_PROG_GREP): Take an additional
14173 match expression argument, as different greps have different
14174 regular expression flavours.
14175 (AC_PROG_FGREP): Pass 'FGREP'. fgrep treats all match chars as
14177 (AC_PROG_EGREP): Pass 'EGREP$'.
14178 (AC_PROG_GREP): Pass 'GREP$'.
14180 2004-04-20 Albert Chin-A-Young <china@thewrittenword.com>
14182 * lib/autoconf/programs.m4 (AC_PROG_GREP): Cache variable
14183 is `ac_cv_path_GREP', not `oc_cv_path_GREP'.
14185 2004-03-29 Paul Eggert <eggert@twinsun.com>
14187 * doc/autoconf.texi (Particular Headers, Particular Types, Generic
14188 Types, Specific Compiler Characteristics, System Services,
14189 Obsolete Macros): Use 'long int', 'short int', 'unsigned int'
14190 etc. consistently instead of 'long', 'short', 'unsigned' etc.
14191 * lib/autoconf/c.m4 (AC_LANG_INT_SAVE(C), AC_C_BIGENDIAN): Likewise.
14192 * lib/autoconf/functions.m4 (AC_FUNC_MMAP, AC_FUNC_SELECT_ARGTYPES):
14194 * lib/autoconf/headers.m4 (AC_HEADER_SYS_WAIT): Likewise.

14203 2004-03-28 Paul Eggert <eggert@twinsun.com>
14205 * doc/autoconf.texi (Particular Structures): AC_STRUCT_TIMEZONE
14206 now defines HAVE_DECL_TZNAME if it is declared, when
14207 HAVE_STRUCT_TM_TM_ZONE is not defined.
14208 * lib/autoconf/types.m4 (AC_STRUCT_TIMEZONE): Implement this.
14209 Do not assume atoi. Rely on HAVE_DECL_TZNAME when testing
14212 2004-03-28 Steven G. Johnson <stevenj@fftw.org>
14214 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Corrected
14215 superfluous backslashing of quotes (") in sed expressions;
14216 thanks to Paul Eggert.
14218 2004-03-26 Steven G. Johnson <stevenj@alum.mit.edu>
14220 * lib/autoconf/fortran.m4 (_AC_PROG_FC): new name of Intel
14221 Fortran compiler is ifort, also added pghpf; thanks to Nelson
14222 H. F. Beebe for the bug report.
14224 2004-03-26 Steven G. Johnson <stevenj@fftw.org>
14226 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): fix for
14227 quoted -cmdline argument in Portland Group compiler (bug
14228 reported by Jeffrey J. Barteet).

14235 2004-03-19 Alexandre Duret-Lutz <adl@gnu.org>
14237 * doc/autoconf.texi (autom4te Invocation): Language Autoconf
14238 inherits from language Autoconf-without-aclocal-m4.
14239 (Customizing autom4te): Adjust example; the cache must now be
14240 disabled for language Autoconf-without-aclocal-m4.

14259 * NEWS: Document these changes.
14261 * doc/autoconf.texi: Avoid macros with unbraced arguments,
14262 they make TeX hang up.

14278 * bin/Makefile.am (edit): Don't use $< in a context where
14279 POSIX doesn't require support for it. Use $@.in instead.
14280 Problem reported by Anthony N. Frasso in
14281 <http://mail.gnu.org/archive/html/autoconf/2004-03/msg00008.html>.

14298 problem on QNX reported by Stephen Rasku in

14301 * bin/Makefile.am ($(srcdir)/autoconf.in): Depend on

14310 AC_SUBST provides no portable way to escape literal newlines.
14312 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS): Ignore all
14313 flags of the form -lcrt*.o, not just -lcrt[01].o and -lcrtbegin.o.
14314 Darwin uses -lcrt2.o and there's little point to cataloging all
14315 the system variants. Partial fix reported by Andreas Waechter in:

14360 use AS_INIT_WITH_SHELL_FN.

14407 _AC_PROG_GREP, and AC_PROG_SED.

14440 * doc/autoconf.texi (Default Includes): Include <stdint.h> even if
14441 HAVE_INTTYPES_H is defined. This is needed on Tru64 5.1b with
14442 Compac C V6.5-207 (dtk), which defines uintmax_t in <stdint.h> but
14443 not <inttypes.h>. Problem reported by Tim Mooney in
14444 <http://mail.gnu.org/archive/html/bug-coreutils/2004-01/msg00147.html>.
14445 * lib/autoconf/headers.m4 (_AC_INCLUDES_DEFAULT_REQUIREMENTS):
14448 * lib/autoconf/programs.m4 (AC_PROG_SED): Use diff, not sed;
14449 otherwise "make check" fails because it forbids cmp (I guess
14450 because cmp treats files as binary on DOS-like systems).
14452 * tests/mktests.sh: Update copyright date to 2004, since some tests
14453 have changed in 2004.
14455 2004-01-23 Gary V. Vaughan <gary@gnu.org>

14463 2004-01-15 Paul Eggert <eggert@twinsun.com>
14465 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Try -std, not -std1, since
14466 -std1 disables some useful extensions on Tru64. Problem reported
14467 by N. Lichtmaier in

14472 * doc/autoconf.texi (Programming in M4sh): Document that
14473 AS_MKDIR_P succeeds if the destination is a symbolic link
14474 to an existing directory.
14475 (Limitations of Usual Tools): Note that mkdir -p might not
14476 succeed on symlinks to directories.
14478 2004-01-13 Paul Hilfinger <hilfinger@CS.Berkeley.EDU>
14480 * lib/autoconf/autoupdate.m4 (AU_DEFUN): Grammar fix in comment.

14494 2004-01-09 Paul Eggert <eggert@twinsun.com>
14496 * lib/autoconf/general.m4: Fix bug: AC_CHECK_SIZEOF evokes a warning
14497 with `autoconf -Wall,error'. Bug reported by Eric Blake in:
14498 http://mail.gnu.org/archive/html/autoconf-patches/2004-01/msg00000.html
14499 (_AC_COMPUTE_INT_COMPILE): Invoke _AC_COMPILE_IFELSE, not
14500 AC_COMPILE_IFELSE, since we now assume our caller invokes
14501 AC_LANG_COMPILER_REQUIRE, for symmetry with _AC_COMPUTE_INT_RUN.
14502 (_AC_COMPUTE_INT_RUN): Likewise, for _AC_RUN_IFELSE instead
14503 of AC_RUN_IFELSE; this avoids the warning mentioned above.
14504 (_AC_COMPUTE_INT): Invoke AC_LANG_COMPILER_REQUIRE.
14506 2004-01-07 Paul Eggert <eggert@twinsun.com>
14508 * lib/autoconf/general.m4 (_AC_LIBOBJS_NORMALIZE): Avoid \$ inside
14509 `"'...'"`, as it's confusing (and I suspect it may not work on
14510 some platforms). The code was incorrect anyway, as it assumed
14511 that \$ evaluated to itself in that context. Reported by
14512 Alexandre Duret-Lutz.
14514 2004-01-07 Alexandre Duret-Lutz <adl@gnu.org>
14516 * lib/autom4te.in (Automake-preselections): Preselect AC_LIBTOOL_TAGS

14544 * lib/autoconf/general.m4 (AC_ARG_PROGRAM):
14545 Use "rm -f" to remove conftest.sed, not plain "rm".
14546 Bug reported by David Relson in
14547 <http://mail.gnu.org/archive/html/autoconf/2004-01/msg00011.html>.
14549 * Makefile.am (autom4te-update):

14567 -c -o might not work. From a suggestion by Kevin Ryde.
14568 (C Compiler, Generating Sources, Limitations
14569 of Usual Tools, Limitations of Make, Making testsuite Scripts):
14570 Don't put '-o' after non-options, as POSIX doesn't allow this.
14571 Mention that cc's name might be gcc or c89 or whatever.
14573 2004-01-04 Kevin Ryde <user42@zip.com.au>
14575 * doc/autoconf.texi: Add various further index entries.

14584 * doc/autoconf.texi (Limitations of Make) <Automatic rule rewriting>:
14585 Documents OSF1/Tru64 make behavior. Replace `VPATH = ../src' by

14587 explanation clearer.

14598 * tests/atlocal.in: Store the result here.

14603 (AT_CHECK_AUTOCONF): Test for the configure script syntax.
14604 * tests/tools.at (Syntax of the shell scripts): Simplify

14678 * lib/autoconf/status.m4 (AC_LINK_FILES): Move the message into
14679 the expanded body, consistently with other macros such as AC_USG.
14681 2003-11-17 Paul Eggert <eggert@twinsun.com>
14683 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Put at least 14 bytes

14872 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Omit quoted
14873 -mGLOB_options_string stuff for Intel ifc, which can cause

14897 * lib/autoconf/fortran.m4 (_AC_PROG_FC_G): Use language-specific
14898 cache variable instead of $G77 to decide whether to include -O2,
14899 since $G77 is specific to Fortran 77.

14903 * lib/autoconf/fortran.m4 (AC_FC_FREEFORM): Support Absoft "-f
14904 free" flag. Re-order flags tested into rough order of popularity.
14906 2003-10-03 Steven G. Johnson <stevenj@alum.mit.edu>
14908 * lib/autoconf/fortran.m4 (AC_PROG_FC): Reverse the order of the
14909 arguments so that it can be used with syntax identical to
14910 AC_PROG_F77, and so that we can more easily decide to
14911 remove/deprecate the DIALECT optional argument in the future if it
14912 proves troublesome.
14913 (AC_FC_FREEFORM): Exit 77 upon failure to fix test suite for
14914 non-freeform-supporting compilers. Document freeform flags.
14916 2003-10-03 Akim Demaille <akim@epita.fr>

14978 <http://mail.gnu.org/archive/html/autoconf/2003-07/msg00042.html>.
14979 (_AS_MKDIR_P_PREPARE): Change "rm -fr ./-p" to the more-conservative
14980 "test -d ./-p && rmdir ./-p". Suggested by Andreas Schwab in:

14985 * lib/autoconf/status.m4 (_AC_OUTPUT_COMMANDS): Make sure the
14986 directory for AC_CONFIG_COMMANDS' first argument exists.
14987 This makes valid the invocation of _AC_SRCPATH that follows.
14988 Reported by Eric Sunshine.

15012 The test suite are sometimes assigning timings incorrectly.
15013 Reported by Henk Krus.
15014 Diagnosed by Nicolas Joly.
15016 * lib/autotest/general.m4 (AT_CLEANUP): Rename AT_help as
15018 Instead of making AT_help a sequence of assignments to grow
15019 $at_help_all, just make AT_help_all be the growing contents of
15020 $at_help_all, and make a single assignment in...
15022 (at_times_skip): Flip the meaning and rename as...
15023 (at_times_p): this.
15024 (AT_INIT): When summarizing the test that ran, remove

15034 (ifnames): chmod -w.
15035 * tests/wrapper.as (AUTOCONF, AUTOM4TE, ): Point to tests/
15036 executables, not bin/ executables! Otherwise all the magic needed
15037 to find non installed files is turned off. This caused a failure
15038 of test 40 and 41 that ran aclocal 1.8 which in turn ran autom4te
15039 as found in its environment (sent by tests/autoreconf): pointing
15040 to bin/autom4te that could not find its files.
15041 * tests/mktests.sh: Force the replacement of generated files, for
15042 the sake of "mv" program that are interactive when overwriting a

15051 2003-09-23 Daniel Jacobowitz <drow@mvista.com> and
15052 Paul Eggert <eggert@twinsun.com>
15054 Trivial change to support GCC's configuration procedure.

15090 willing to edit the output files.
15092 2003-09-10 Akim Demaille <akim@epita.fr>

15095 and AC_FC_FREEFORM.

15137 2003-09-02 Steven G. Johnson <stevenj@alum.mit.edu>
15139 Add support for newer Fortran dialects. The F77 interface is
15140 unchanged, and continues to support Fortran 77. New FC macros
15141 correspond to all the old F77 macros, with output variables FC,
15142 FCFLAGS, and FCLIBS. AC_PROG_FC defaults to picking the newest
15143 available dialect, but older dialects can be specified. There are
15144 new macros AC_FC_SRCEXT to set the source extension, and
15145 AC_FC_FREEFORM to accept free-form source files.
15147 * lib/autoconf/c.m4 (_AC_LANG_PREFIX(C), _AC_LANG_PREFIX(C++)):

15245 * bin/autom4te.in: Adjust to output the call stack.

15271 2003-08-21 Akim Demaille <akim@epita.fr>
15273 First stab at preserving warnings between calls to autom4te,
15274 including when the cache is used.
15276 There are still several issues: (i) there are too many runs of m4
15277 (one for include, one for warnings, and some more), (ii) warnings
15278 spreading on several lines are not handled gracefully, (iii) the
15279 code meant to have the call stack display for errors does not work
15280 (its handling should move from m4 to autom4te).
15282 * bin/autom4te.in Autom4te::Channels, Autom4te::ChannelDefs):
15284 (@preselect): Add m4_warn.
15285 ($exit_status): Remove, use $exit_code.
15286 ($help): Use Autom4te::ChannelDefs::usage.
15287 (&handle_m4): No longer define the m4_warnings.
15288 At each run, extract and report the warnings.
15289 Always cache the result, including if the exit status is on
15290 failure, since if nothing changes, we should result in the same
15291 failure, hence we can use the cache.
15292 * lib/m4sugar/m4sugar.m4 (m4_warning_ifelse, _m4_warning_ifelse)
15293 (_m4_warning_error_ifelse, __m4_warning_error_ifelse, _m4_warn):
15295 (m4_warn): Redefine as a do-nothing: it is its invocation that
15296 matters, as warnings are now reported via traces.
15297 * lib/autoconf/general.m4 (AC_DIAGNOSE): Don't make it a copy of
15298 the contents of m4_warn: make it _call_ m4_warn, so that tracing
15299 the latter reveals calls to the former.
15303 * tests/m4sugar.at (m4@&t@_warn): Use existing warning categories.

15325 (&catfile): Remove.
15326 * bin/autoheader.in, bin/autoreconf.in, bin/autoupdate.in,
15327 * bin/autoscan.in: Adjust.
15329 2003-08-20 Akim Demaille <akim@epita.fr>
15331 * bin/autoheader.in: Remove duplicate 'use Autom4te::FileUtils'.
15332 Reported by Alexandre Duret-Lutz.
15334 2003-08-20 Akim Demaille <akim@epita.fr>
15336 * bin/autoupdate.in, bin/autoheader.in, bin/autoreconf.in,
15337 * bin/autom4te: Adjust.
15338 In particular, be Autoconf tools are really silent when properly
15339 working, bind the verbosity of the 'note' channel to $verbose.
15340 * lib/Autom4te/General.pm (&find_file, &mtime, &update_file)
15341 (&xsystem, &contents): Remove, since they are exported by...
15342 * lib/Autom4te/FileUtils.pm: this.

15345 * lib/Autom4te/FileUtils.pm: here.

15404 shorter column three. Add DESCRIPTION to log file content.

15462 2003-06-23 Akim Demaille <akim@epita.fr>
15464 * lib/autotest/general.m4 (AT_INIT): Report a single config.log,
15465 not all of them. This fixes 1. the fact that when testing
15466 Autoconf there are many many config.log, 2. the incorrect use of
15467 top_srcdir to find config.log.
15468 Don't mix the detailed output of failed test with the summary of
15469 failures. Rather, append detailed log afterwards.
15471 2003-06-23 Akim Demaille <akim@epita.fr>
15473 * tests/local.at (AT_CHECK_CONFIGURE): Adjust to the verbose being

15556 2003-05-23 Alexandre Duret-Lutz <adl@gnu.org>
15558 * lib/Autom4te/General.pm (END): Rewrite exit code processing.
15559 Do not call `_exit()', simply modify `$?'.
15560 (xsystem): Reset $! before running system, and check it afterward.
15561 * tests/tools.at (autoupdating AC_PREREQ): Expect exit status
15562 63 for version mismatches.

15588 * lib/autoconf/c.m4 (_AC_PROG_CXX_EXIT_DECLARATION):
15589 Remove `#include <stdlib.h>' from the list; we should never
15590 make confdefs.h include <stdlib.h> or <cstdlib>, because the
15591 resulting namespace pollution would cause other tests to fail.
15592 Configure scripts run with some older versions of g++ and HP's
15593 aCC would fail due to such an #include. Problems reported by
15594 Matthew Mueller in <http://bugs.debian.org/120704> and by
15596 <http://mail.gnu.org/archive/html/autoconf/2003-05/msg00063.html>.
15597 In the test, use the test declaration before including <stdlib.h>,
15598 as that's closer to how it'll be used.

15602 * doc/autoconf.texi (Header Portability): ucred.h.
15605 2003-05-22 Paolo Bonzini <bonzini@gnu.org>
15607 Overhaul Autotest's logging: generate separate log files
15608 in testsuite.dir/NNN/testsuite.log, and append them to
15609 testsuite.log instead of re-running the test verbosely.
15611 * lib/autotest/general.m4 (AT_INIT): Use a single redirected
15612 file descriptor, write 0 to at_status_file instead of setting
15613 at_status=0, initialize some new variables (at_status_file,
15614 at_group_log, at_suite_log, at_tee_pipe). Remove the cruft
15615 to rerun the tests, instead append the at_group_log to the
15616 at_suite_log when a test fails.
15617 (AT_SETUP): pipe the test case's output into at_tee_pipe,
15618 with the AS_MESSAGE_LOG_FD redirected to stdout.
15619 (AT_CLEANUP): save the output status in $at_status_file
15620 and restore it, redirect the AS_MESSAGE_LOG_FD back to
15621 its original place.
15622 (AT_CHECK): since tests are run with a redirected stdout,
15623 and used to be re-run in verbose mode, turn some $at_verbose
15624 into echo, and don't redirect the output of testing stdout
15627 * lib/autotest/autoconf.texi (testsuite Scripts): Update

15748 2003-05-06 Akim Demaille <akim@epita.fr>
15750 Don't try to be smart with aclocal 1.8+ because (i) aclocal no
15751 longer updates aclocal.m4 if useless, (ii) if a file m4_included
15752 by aclocal.m4 is changed it might require the importing of another
15753 m4 extension file, i.e., aclocal must be run.
15755 * bin/autoreconf.in (&run_aclocal, $aclocal_supports_force): New.
15756 (&parse_args): Use --force with aclocal if required and supported.

15770 2003-04-29 Derek Price <derek@ximbiot.com>
15772 * lib/autotest/general.m4 (AT_KEYWORDS): Don't use a comma as the
15773 seperator with m4_append_uniq(). It doesn't work.
15774 (AT_CLEANUP): Add `;' to end of at_help_all.
15775 (AT_INIT): Allow --keywords to be specified more than once. When
15776 grepping $at_help_all for keywords, use the field and keyword

15856 * tests/torture.at (Configuring subdirectories): Require aclocal
15857 1.4, otherwise the test fails, as it does support configure.ac.

15948 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Translate colons,
15949 to cope with DOS-style absolute paths, when constructing
15952 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS, _AC_OUTPUT_FILES):
15953 When constructing paths with IFS=:, quote the path. If we're
15954 constructing a DOS-style absolute path, we don't want to split it

15978 format starting with "-".
15980 2003-02-20 Alexandre Duret-Lutz <adl@gnu.org>
15982 * doc/autoconf.texi (Limitations of Make): `foo=bar make -e'
15983 is not portable inside Makefile.
15985 2003-02-20 Akim Demaille <akim@epita.fr>
15987 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): When

16005 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Define $1 to an
16006 innocuous variant befor including <limits.h> or <assert.h>. This
16007 works around a bug reported by Albert Chin: HP-UX 11i
16008 (and earlier versions) have a <limits.h> that declares
16009 gettimeofday and many other functions.
16011 2002-12-03 Paul Eggert <eggert@twinsun.com>
16015 * NEWS, configure.ac: Update version.
16017 * doc/fdl.texi: Upgrade to FDL version 1.2.
16019 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Use the function f
16020 nontrivially in main's body, so that f's external declaration is
16021 not optimized away in AIX. This should fix the bug reported by
16023 <http://mail.gnu.org/pipermail/autoconf/2002-November/014508.html>.
16025 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C),
16026 _AC_PROG_PREPROC_WORKS_IFELSE): Use <limits.h> if __STDC__ is
16027 defined, to support freestanding compilers. This should fix the
16028 bug reported by Momchil Velkov in
16029 <http://mail.gnu.org/pipermail/autoconf/2002-November/014490.html>.
16031 * doc/autoconf.texi (Obsolete Macros): Fix typos (insert empty
16032 arg, AC_DEFINE -> AC_DEFINE_UNQUOTED) in documentation for

16043 * bin/autom4te.in (at_flatten): rewritten to avoid M4 problem when
16044 \(.*\) match is too long and there is something more to be checked.
16045 <http://mail.gnu.org/pipermail/autoconf/2002-November/014524.html>

16063 Update from masters.
16065 2002-11-14 Akim Demaille <akim@epita.fr>
16067 * Makefile.maint: Sync with Bison, i.e.:
16068 (po-check): Scan .l and .y files instead of the
16069 .c and the .h files that they generate. This fixes the bug
16070 reported by Tim Van Holder in:
16071 <http://mail.gnu.org/pipermail/bison-patches/2002-November/001352.html>
16072 Look for N_ as well as for _. Try to avoid matching #define for
16076 2002-11-14 Akim Demaille <akim@epita.fr>
16078 * doc/autoconf.texi (C Compiler): Compiling several files at once.

16084 From Paul Eggert and Albert Chin-A-Young.
16086 2002-11-14 Kevin Ryde <user42@zip.com.au>
16088 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Initialize f=$1 rather
16089 than assigning in main, to avoid HP cc +O3 optimizing it away.
16091 2002-11-12 Peter Eisentraut <peter_e@gmx.net>
16093 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Add -q
16094 option. Process --recheck after parsing all options. Pass -q
16095 option to configure on --recheck.
16096 (AC_OUTPUT): Pass -q from configure to config.status.
16097 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Strip -q from
16098 arguments to record.
16099 * doc/autoconf.texi (config.status Invocation): Document
16100 config.status -q option.
16102 2002-11-07 Alexandre Duret-Lutz <adl@gnu.org>
16104 * bin/autoscan.in (scan_file): Scan Makefile.am too. Ignore
16105 Makefile.in if Makefile.am exists.
16106 (output): Strip `.am' from Makefiles. Don't
16107 output AC_CONFIG_FILES if no Makefiles were found.

16114 (local_updates): New.
16116 2002-11-06 Akim Demaille <akim@epita.fr>
16118 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY): Wrap the `f'
16119 declaration in extern "C" too.
16120 Reported by Roberto Bagnara.
16122 2002-11-06 Akim Demaille <akim@epita.fr>
16124 * tests/torture.at (Configuring subdirectories): Don't use grep
16126 * doc/autoconf.texi (Limitations of Usual Tools): Grep -w.
16127 Reported by Ezra Peisach.
16129 2002-11-05 Akim Demaille <akim@epita.fr>
16131 * lib/autoconf/autoheader.m4 (_AH_TEMPLATE_OLD, _AH_VERBATIM_OLD):
16133 We _have_ to stop using the old compatibility scheme that tried to
16134 avoid useless backslashes because Libtool 1.4.3 contains a
16135 AC_DEFINE([error_t], [int],
16136 [Define to a type to use for \`error_t' if it is not
16137 otherwise available.])
16138 We _have_ to quote the single quote and backslashes with \. The
16139 old compatibility scheme saw that ` was backslashed, and therefore
16140 did not quote the single quote. Hence before this patch, Autoconf
16141 was not compatible with Libtool.

16532 Reported by Alexandre Duret-Lutz.
16534 * bin/autom4te.in (&parse_args): Do not prepend `--reload-state'

16539 (&up_to_date): If a file that was included according to the cache

16554 * lib/Autom4te/General.pm (&update_file): Use `verbose' to report
16555 if some file was changed instead of `print'.
16556 * bin/autoheader.in: Suggest AC_DEFINE with 3 args when needed.

16590 file name to enable parallel executions.
16591 From Sam Varshavchik.
16593 2002-10-08 Akim Demaille <akim@epita.fr>
16595 * bin/autoreconf.in (&autoreconf): Run autopoint before the first
16596 aclocal invocation, as Gettext macros might not be visible to
16598 Instead of blindly running autopoint, scan configure.ac (not the
16599 traces) for AM_GNU_GETTEXT_VERSION uses, as autopoint does.
16600 Reported by Paul D. Smith.
16602 2002-10-08 Paul Eggert <eggert@twinsun.com>
16604 Work around problems found when POSIXLY_CORRECT=1 is set.
16605 None of this seems to have anything to do with POSIX, really,
16606 but it's how Perl getopt works.
16607 * bin/autom4te.in (parse_args): Configure GetOpt with
16609 * doc/autoconf.texi (Invoking autom4te):
16610 --warning -> --warnings.

16632 * tests/torture.at (Configuring subdirectories): Be robust to
16633 users who use config.site to require for a cache: in this case,
16634 the two last configure runs, using two different sets of
16635 arguments, trigger a legitimate error.

16674 (autoscan.list): New target --this file is no longer a source.
16675 (autoscan.pre): New file.
16677 2002-09-28 Akim Demaille <akim@epita.fr>
16679 * bin/autoscan.in (@kinds): Make them singular.

16682 tracking changes in autoscan.list.
16683 * lib/autoscan/autoscan.list (function): Strip comments, sort.
16685 2002-09-28 Akim Demaille <akim@epita.fr>

16695 * lib/autoscan/functions, lib/autoscan/headers,
16696 * lib/autoscan/identifiers, lib/autoscan/makevars,
16697 * lib/autoscan/programs: Make the `kind' explicit, i.e., each
16698 `functions' line is now prefixed with `function:'.
16699 * bin/autoscan.in (&init_tables): Adjust.
16701 2002-09-28 Akim Demaille <akim@epita.fr>
16703 From now on, autoscan files must always map a macro name to a
16704 word: there is no `default' macro for autoscan.
16706 * bin/autoscan.in (&init_tables): Reject entries with no macro at
16708 * lib/autoscan/functions, lib/autoscan/headers: Make the macro
16711 2002-09-28 Akim Demaille <akim@epita.fr>
16713 * bin/autoscan.in (%c_keywords): Remove.

16729 Thanks to Bill Moseley and Paul Eggert.
16730 * lib/m4sugar/m4sh.m4 (AS_TMPDIR): $2 is the directory into which
16731 the tmpdir must be created.
16732 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Have the tmp
16733 dir be in the build tree, instead of $TMPDIR.

16737 * bin/autoscan.in: Improve the comments.

16746 Reported by Ralf Corsepius.
16747 * doc/autoconf.texi (autoreconf Invocation): Likewise.
16749 2002-09-26 Akim Demaille <akim@epita.fr>
16751 Single suffix rules and seperated dependencies are not portable.
16753 * doc/autoconf.texi (Installation Directory Variables): Update.
16754 (Limitations of Make): Some about `Single Suffix Rules and
16755 Separated Dependencies'.
16756 * bin/Makefile.am (autoconf, autoheader, autoreconf, autoupdate)
16757 (ifnames, autoscan, autom4te): Un-factor into several rules.
16759 2002-09-25 Paul Eggert <eggert@twinsun.com>
16761 * BUGS (Interoperability bugs): New section. Mention libtool
16762 1.4.2, configure.ac, and AC_CONFIG_AUX_DIR interoperability bug.
16764 2002-09-24 Paul Eggert <eggert@twinsun.com>
16766 Fix a portability bug reported by Alexandre Duret-Lutz: Solaris 8
16767 make handles suffix-rules differently from GNU make.
16769 * bin/Makefile.am (SUFFIXES, .in): Remove.
16770 (autoconf autoheader autoreconf autoupdate ifnames autoscan autom4te):
16771 Move the body of the old .in rule here.
16773 2002-09-16 Akim Demaille <akim@epita.fr>
16775 i960 compilers create `b.out' files by default.
16776 Reported by Ralf Corsepius.
16778 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT): Remove b.out files.
16779 (_AC_COMPILER_EXEEXT_DEFAULT): Adjust to b.out.
16781 2002-09-13 Paul Eggert <eggert@twinsun.com>
16783 * doc/autoconf.texi (Particular Headers): Remove obsolete
16784 reference to `struct timezone' in the description of

16795 2002-09-13 Akim Demaille <akim@epita.fr>
16797 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Suggest
16798 reading config.log when the compiler is rejected.
16799 Suggested by Guido Draheim.
16801 2002-09-13 Akim Demaille <akim@epita.fr>
16803 * bin/autoreconf.in: Don't use Cwd::chdir, since in its internals
16804 (chdir_init) might hang when stat'ing mounted directories.
16805 Reported by Vance Shipley.
16807 2002-09-12 Akim Demaille <akim@epita.fr>
16809 * bin/autoscan.in (&parse_args): Pass a reference to the lists, not
16812 2002-09-12 Akim Demaille <akim@epita.fr>
16814 * doc/autoconf.texi (Defining Symbols): Present two different
16815 prototypes for AC_DEFINE and AC_DEFINE_UNQUOTED to emphasize the
16816 difference between 1 argument calls, and 2-3 argument calls.
16818 2002-09-12 Peter Eisentraut <peter_e@gmx.net>
16820 * doc/autoconf.texi: Review grammar and punctuation.
16822 2002-09-11 Paul Eggert <eggert@twinsun.com>
16824 * doc/autoconf.texi: Fix minor formatting, spelling, and
16826 (Defining Symbols): Explain that AC_DEFINE(var) defaults to 1, but
16827 AC_DEFINE(var,,description) does not; and the AC_DEFINE(var) case
16830 2002-09-11 Akim Demaille <akim@epita.fr>
16832 * doc/autoconf.texi (Questions): Rename as...
16834 (Defining Directories): New.
16836 2002-09-09 Akim Demaille <akim@epita.fr>
16838 * doc/autoconf.texi (Making testsuite Scripts): Update.
16839 Suggested by Nishio Futoshi.
16841 2002-09-09 Koji Arai <JCA02266@nifty.ne.jp>
16843 * doc/autoconf.texi (Making testsuite Scripts): Use `@@' where a
16844 plain `@' is wanted.
16846 2002-09-09 Akim Demaille <akim@epita.fr>
16848 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Keep the
16849 `duplicates', since the algorithm was too naive and could keep
16850 `--prefix=1 --prefix=2 --prefix=1' as `--prefix=1 --prefix=2', and
16851 keep `--prefix foo --prefix bar' as `--prefix foo bar'.
16852 Reported by Ralf Corsepius.
16853 * tests/torture.at (Configuring subdirectories): Exercise these
16856 2002-09-09 Akim Demaille <akim@epita.fr>
16858 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Use $srcdir when
16859 looking for a replacement file.
16860 * lib/autoconf/general.m4 (AC_CHECK_DECLS): Check that the
16861 directory is relative.
16862 * doc/autoconf.texi (Generic Functions): Clarify the replacement
16863 directory definition.
16864 Reported by Andreas Schwab and Jim Meyering.
16866 2002-09-06 Akim Demaille <akim@epita.fr>
16868 * doc/autoconf.texi (Setting Output Variables): Clarify what
16869 precious variables are.
16870 Suggested by Pontus Skoeld.
16872 2002-09-05 Akim Demaille <akim@epita.fr>
16874 * bin/Makefile.am (autoconf, autoheader, autoreconf, autoupdate)
16875 (ifnames, autoscan, autom4te): Since we don't only depend on
16876 configure.ac variables (such as VERSION etc.), but also on prefix
16877 and so forth, depend on Makefile, not configure.ac.
16878 Reported by Alexandre Duret-Lutz.
16879 * doc/autoconf.texi (Installation Directory Variables): Adjust.
16881 2002-09-05 Kevin Ryde <user42@zip.com.au>
16883 * doc/autoconf.texi (Limitations of Make): HP-UX trailing backslashes
16884 doesn't seem to be confined to ia64, just say "some versions".
16886 2002-09-04 Akim Demaille <akim@epita.fr>
16888 * Makefile.am, doc/Makefile.am: Remove pdf targets, handled by
16890 * Makefile.am (maintainer-clean-local): Remove.
16891 (MAINTAINERCLEANFILES): Remove COPYING.
16893 2002-09-03 Paul Eggert <eggert@twinsun.com>
16895 * doc/autoconf.texi (Configuration Commands): Remove obsolete
16896 example for AC_CONFIG_COMMANDS_PRE. Problem reported by Marcus
16899 2002-09-03 Akim Demaille <akim@epita.fr>
16901 * configure.ac: Bump to 2.53d.
16902 * Makefile.am (AUTOMAKE_OPTIONS): Require 1.6c, i.e., CVS Automake
16903 as of today, on Automake's team suggestion.
16905 2002-09-03 Akim Demaille <akim@epita.fr>
16909 2002-09-02 Akim Demaille <akim@epita.fr>
16911 * bin/autom4te.in (parse_args): Don't honor AUTOM4TE_PATH and
16913 * configure.ac: Disable SITE_MACRO_DIR.
16915 2002-09-02 Jim Meyering <meyering@lucent.com>
16917 * doc/autoconf.texi (AC_SYS_POSIX_TERMIOS): Reflect renaming: s/am/ac/,
16918 i.e., change am_cv_sys_posix_termios to ac_cv_sys_posix_termios.
16919 Also, tweak grammar: s/make sure to/be sure to/.
16921 2002-09-02 Paul Eggert <eggert@twinsun.com>
16923 * doc/autoconf.texi (Limitations of Builtins): Explain why logical
16924 directory names are generally preferable to physical names.
16926 2002-09-02 Akim Demaille <akim@epita.fr>
16928 * lib/Autom4te/General.pm (&update_file): s/die/error/.
16929 Reported by Raja R. Harinath.
16930 * bin/autoheader.in, bin/autoreconf.in, bin/autoscan.in,
16931 * bin/autoupdate.in: Use error instead of die.
16933 2002-09-01 Paul Eggert <eggert@twinsun.com>
16935 * tests/mktests.sh (ac_exclude_egrep, au_exclude_egrep): Use
16936 ordinary shell concatenation rather than echo+tr+sed command that
16937 runs afoul of a long-line-related sed bug in Solaris 8.
16939 * bin/autoheader.in (parse_args): --warning -> --warnings.
16941 * bin/autoconf.as: Work even if "ls" outputs "FOO not found" to
16942 stdout, as traditional "ls" does.
16943 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT,
16944 _AC_COMPILER_EXEEXT_O): Likewise.
16945 * doc/autoconf.texi (Limitations of Usual Tools): Add "ls".
16947 * bin/autoconf.as: Add --prepend-include option. This patch was
16948 applied to bin/autoconf.in in the 2002-07-17 patch by Mark D. Roth,
16949 but bin/autoconf.in is generated automatically from bin/autoconf.as.
16951 * bin/autoconf.in, configure: Regenerate.
16953 * doc/autoconf.texi (Special Shell Variables): Mention
16954 ENV, MAIL, MAILPATH, PS1, PS2, PS4. Index PWD.
16956 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Unset ENV, MAIL,
16957 MAILPATH and set PS1, PS2, PS4 to default values, to work
16958 around bug in pre-3.0 UWIN ksh reported by Bruce Lilly.
16959 For LC_ALL etc, first try to set to "C" as POSIX requires and as
16960 the Autoconf documentation specifies; fall back to "unset" only if
16961 this fails. Use a shell for-loop for this rather than an m4 loop,
16962 to shorten the output script.
16964 2002-08-30 Paul Eggert <eggert@twinsun.com>
16966 * doc/autoconf.texi (Special Shell Variables): Mention POSIX
16967 1003.1-2001's requirements for CDPATH. Give a simpler workaround
16968 for the CDPATH problem. Document PWD.
16969 (Limitations of Builtins): Document the problem that "cd $foo" and
16970 "ls $foo" may refer to different directories in shells conforming
16971 to POSIX 1003.1-2001. Use PS1 rather than CDPATH for "unset"
16972 example, since the old example is now out of date.
16974 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Reject FOO if "cd
16975 FOO" and "ls FOO" talk about different directories; this catches
16976 problems when POSIX 1003.1-2001 "cd" fails due to symlink
16979 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Use AS_UNSET instead
16980 of rolling our own unset.
16981 (_AS_PREPARE): $as_unset CDPATH instead of AS_UNSETting it, since
16982 in practice we needn't worry about CDPATH if unset doesn't work.
16984 * Makefile.in, aclocal.m4, bin/Makefile.in,
16985 config/Makefile.in, doc/Makefile.in, lib/Makefile.in,
16986 lib/Autom4te/Makefile.in, lib/autoconf/Makefile.in,
16987 lib/autoscan/Makefile.in, lib/autotest/Makefile.in,
16988 lib/emacs/Makefile.in, lib/m4sugar/Makefile.in, man/Makefile.in,
16989 tests/Makefile.in: Regenerate with Automake 1.6.3.
16991 * config/config.guess, config/config.sub, config/mkinstalldirs:
16994 * configure: Regenerate with self.
16996 2002-08-30 Kevin Ryde <user42@zip.com.au>
16998 * doc/autoconf.texi (Limitations of Usual Tools): Notes on "cc"
17001 2002-08-29 Rainer Orth <ro@TechFak.Uni-Bielefeld.DE>
17003 * bin/autom4te.in (Request::load): Correctly test for "do" read
17006 2002-08-29 Akim Demaille <akim@epita.fr>
17008 * lib/Autom4te/General.pm (&xqx): New.
17009 (&xsystem): Use WIFEXITED and WEXITSTATUS instead of decoding $? by
17010 hand, which is not portable.
17012 * bin/autom4te.in: Use them.
17013 Use &error instead of die.
17014 * tests/m4sugar.at (m4_warn, m4_require: circular dependencies):
17017 2002-08-17 Paul Eggert <eggert@twinsun.com>
17019 * lib/autoconf/fortran.m4 (AC_PROG_F77): Remove fc from the
17020 default list of compilers to try, since it was long ago superseded
17021 by the ksh fc builtin. Suggested by Steven G. Johnson.
17023 2002-07-31 Alexandre Duret-Lutz <duret_g@epita.fr>
17025 * doc/autoconf.texi (Invoking autom4te): End the option table,
17026 fixing a bug introduced by the previous patch.
17027 (Limitations of Make): Add a 'target lookup' subentry in the
17028 'VPATH' entry. Rewrite all `make' occurences as `@command{make}'.
17030 2002-07-29 Mark D. Roth <roth@feep.net>
17032 * bin/autom4te.in: Remove --include-envvar and --site-macro-subdir
17033 options and use $AUTOM4TE_PATH.
17034 * doc/autoconf.texi: Remove documentation of autom4te
17035 --include-envvar and --site-macro-subdir options and document
17036 use of $AUTOM4TE_PATH.
17037 * lib/autom4te.in: Remove --include-envvar and --site-macro-subdir
17038 arguments from each language section.
17040 2002-07-29 Paul Eggert <eggert@twinsun.com>
17042 * doc/install.texi: Include copyright symbol in copyright notice.
17044 * Makefile.am (MAKEINFO): Remove; it's a user-specified macro.
17046 (AM_MAKEINFOFLAGS): New macro.
17047 * doc/Makefile.am (MAKEINFO, AM_MAKEINFOFLAGS): Likewise.
17048 * Makefile.am (INSTALL): Use the new macros.
17049 Use -o rather than --output, since "missing" does not grok --output.
17051 2002-07-25 Alexandre Duret-Lutz <duret_g@epita.fr>
17053 * doc/autoconf.texi (Limitations of Make): Escaped newlines in
17054 comments do not always work. Never trust the exit status of
17057 2002-07-24 Kevin Ryde <user42@zip.com.au>
17059 * doc/autoconf.texi (Limitations of Make, Making testsuite Scripts):
17060 Untabify, since tabs are not enjoyed by texi2dvi and makeinfo.
17062 2002-07-23 Paul Eggert <eggert@twinsun.com>
17064 * lib/m4sugar/m4sh.m4 (_AS_PATH_SEPARATOR_PREPARE):
17065 Use PATH="/nonexistent;.", not PATH=".;.", as FreeBSD ksh2002
17066 apparently treats PATH="nonexistent" as if it contained ".".
17067 Bug reported by Stefan `Sec' Zehl.
17069 2002-07-22 Alexandre Duret-Lutz <duret_g@epita.fr>
17071 * doc/autoconf.texi (Limitations of Make): Mention the special
17072 handling of the obj/ directory by BSD make.

17106 Alexandre Duret-Lutz <duret_g@epita.fr>
17108 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Install

17114 description of the tarname default.
17116 2002-07-17 Andreas Buening <andreas.buening@nexgo.de>
17118 * lib/autoconf/functions.m4 (AC_FUNC_FORK): Don't set
17119 ac_cv_func_fork_works before running _AC_FUNC_FORK, do it if the
17120 latter was not run.
17122 2002-07-17 Akim Demaille <akim@epita.fr>
17124 * lib/Autom4te/General.pm (find_file): Browse the directories in
17125 the order they are given.

17130 * tests/wrapper.as: this.
17131 * tests/Makefile.am, configure.ac: Adjust.
17133 2002-07-17 Mark D. Roth <roth@feep.net>
17135 * configure.ac: Add --enable-site-macro-dir option.

17341 AC_FUNC_FNMATCH now tests only for POSIX compatibility.
17342 AC_FUNC_FNMATCH_GNU also tests for GNU extensions.
17343 Both macros now accept an optional source-dir arg.
17344 New macro AC_GNU_SOURCE to define _GNU_SOURCE.
17346 * NEWS: Document this.
17347 * doc/autoconf.texi (Particular Functions, UNIX Variants): Likewise.
17349 * lib/autoconf/functions.m4 (_AC_FUNC_FNMATCH): New macro.
17350 (AC_FUNC_FNMATCH): Use it. Test only for POSIX conformance,
17351 not for GNU extensions; this undoes part of the 2000-11-03 change,
17352 reverting to 2.13-compatible behavior.

17360 * lib/autoconf/headers.m4 (AC_HEADER_TIOCGWINSZ):
17361 Don't require AC_SYS_POSIX_TERMIOS. The test is unnecessary,

17363 Bug reported by Stephen Gildea.
17365 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
17366 If prototypes are supported, use them to check this at compile-time,
17367 instead of trying to check it at run-time. If we must do a run-time
17368 check, assume that setvbuf is standard when cross-compiling, as
17369 nonstandard setvbuf occurs only on ancient and unlikely hosts.
17370 Bug reported by Paul D. Smith.
17372 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Add optional
17373 argument specifying location of getloadavg.c. This removes a
17374 FIXME. This idea was taken from Jim Meyering's implementation in
17376 * doc/autoconf.texi (Particular Functions): Document this.
17377 Also, mention HAVE_NLIST_H rather than NLIST_STRUCT, since
17378 that's what the code does; this fixes a bug reported by

17383 * bin/autoreconf.in (autoreconf): Rewrite to use Gettext's
17384 autopoint instead of gettextize.
17385 ($uses_alocal): Rename as...
17386 ($uses_aclocal): this.
17387 * doc/autoconf.texi (autoreconf Invocation): Adjust.
17388 Suggested by Bruno Haible.

17396 * bin/autoreconf.in (autoreconf): Don't age aclocal.m4's input
17397 files to be 1 second older; just set them to be the same time.
17398 Also, sleep 1 second after the first aclocal, to work around
17399 problems with sub-second time stamps on the input files.
17401 2002-04-29 Thien-Thi Nguyen <ttn@gnu.org>
17403 * doc/autoconf.texi: Mention "set -e -x" lossage

17412 2002-04-29 Akim Demaille <akim@epita.fr>
17414 * tests/m4sh.at (LINENO): If testsuite itself is rewritten because
17415 of lack of $LINENO support, then the test will compare the $LINENO
17416 in testsuite vs. the lineno in the test file. This is wrong, of
17418 Be sure to protect it.
17419 Reported by Patrick Welche.
17421 2002-04-25 Akim Demaille <akim@epita.fr>
17423 * doc/autoconf.texi (Obsolete Macros): Typo.
17424 Reported by Vladimir Volovich.
17426 2002-04-25 Akim Demaille <akim@epita.fr>
17428 * bin/autoreconf.in (autoreconf): Don't let aclocal.m4 be older
17429 than some of the input files, hence, on the second run of aclocal,
17430 if some of its input are younger, make them older.
17431 Suggested by Paul Eggert.
17433 2002-04-25 Akim Demaille <akim@epita.fr>
17435 * doc/autoconf.texi (Limitations of Usual Tools): sed and `!'.

17444 (_AC_INIT_PREPARE): Use them to log them.
17445 (_AC_SUBST, _AC_SUBST_SED_PROGRAM): Remove.
17446 (AC_SUBST, AC_SUBST_FILE): Instead of buliding the
17447 _AC_SUBST_SED_PROGRAM, store the list of output files/variables in
17448 _AC_SUBST_FILES and _AC_SUBST_VARS.
17449 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Adjust.
17451 2002-04-24 Akim Demaille <akim@epita.fr>
17453 * bin/autoreconf.in (autoreconf): Run automake after autoconf and
17454 autoheader, so that automake does not complain about a missing

17614 (_AC_CONFIG_COMMAND, _AC_CONFIG_LINK): New.
17615 Use dnl, not the KILL diversion.
17617 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_COMMANDS)
17618 (AC_CONFIG_LINKS): here.
17620 Don't use the KILL diversion, as it kills spurious output, which
17621 results in failures being hidden.
17622 Use m4_defn where appropriate.
17623 (AC_CONFIG_IF_MEMBER): Kill the real bug: a spurious parenthesis
17624 after the second argument.
17626 * lib/autom4te.in (Autoconf, Autotest, M4sh): Don't pass --warning
17627 syntax, as it is provided by M4sugar.
17628 * tests/torture.at (Multiple AC_CONFIG_FILES): New.
17630 2002-04-03 Andreas Schwab <schwab@suse.de>
17632 * lib/m4sugar/m4sugar.m4 (m4_bmatch): Make sure m4_bregexp is not
17633 expanded if $# <= 2.
17635 * bin/autoreconf.in (autoreconf): Run automake after rerunning
17638 2002-04-03 Akim Demaille <akim@epita.fr>
17640 * lib/autoconf/lang.m4 (_AC_COMPILER_OBJEXT_REJECT)

17643 (_AC_COMPILER_EXEEXT_DEFAULT, _AC_COMPILER_EXEEXT_O)
17644 (_AC_COMPILER_OBJEXT): Use them.
17645 Fixes Debian #138666.
17647 2002-04-02 Peter Eisentraut <peter_e@gmx.net>
17649 Integrate AC_PROG_CC_STDC into AC_PROG_CC.
17651 * lib/autoconf/c.m4 (AC_PROG_CC_STDC): Rename to _AC_PROG_CC_STDC.
17652 AU_DEFUN old name. Use _AC_COMPILE_IFELSE.
17653 (AC_PROG_CC): Call _AC_PROG_CC_STDC.
17654 (AC_C_INLINE): Do not require AC_PROG_CC_STDC.
17655 (AC_C_CONST): Same.
17656 (AC_C_INLINE): Same.
17657 (AC_C_PROTOTYPES): Same. Require AC_PROG_CC instead.
17658 * doc/autoconf.texi, NEWS: Document.

17667 2002-03-28 Kevin Ryde <user42@zip.com.au>
17669 * lib/autoconf/c.m4 (AC_C_INLINE): Test with a typedef return value,
17670 to avoid versions of HP C which don't allow that.
17672 2002-03-27 Paul Eggert <eggert@twinsun.com>
17674 * lib/m4sugar/m4sh.m4 (_AS_BASENAME_PREPARE): New macro.
17675 (AS_SHELL_SANITIZE): Invoke it.
17676 (AS_BASENAME): AS_REQUIRE it, and use $as_basename.

17680 * doc/autoconf.texi (Portable Shell): Add pointers to FAQs.
17682 2002-03-26 Akim Demaille <akim@epita.fr>
17684 * doc/autoconf.texi (Introduction): The GNATS base moved.
17686 2002-03-25 Paul Eggert <eggert@twinsun.com>
17688 * tests/m4sh.at: Don't rely on "PATH=test:$PATH test-1" working
17689 as POSIX requires, as it doesn't work with Zsh.
17690 * doc/autoconf.texi (Assignments): Document the problem.
17692 2002-03-25 Alexandre Duret-Lutz <duret_g@epita.fr>
17694 * doc/autoconf.texi (Limitations of Make): Mention more issue
17695 about VPATH, overriding of macros in sub-makes, and handling of
17698 2002-03-21 Paul Eggert <eggert@twinsun.com>
17700 * doc/autoconf.texi (Here-Documents): Mention Solaris 8 dtksh
17701 problem with here-document buffer boundaries.
17703 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Unset ENV and BASH_ENV
17704 when reinvoking the shell, to work around problems with installers
17705 who put strange things like "cd" commands in their environments.
17707 2002-03-19 Akim Demaille <akim@epita.fr>
17709 * tests/semantics.at (AC_C_BIGENDIAN): s/unknow/unknown/.

17718 2002-03-19 Akim Demaille <akim@epita.fr>

17721 From Nishio Futoshi.
17723 2002-03-19 Akim Demaille <akim@epita.fr>
17725 * lib/m4sugar/m4sugar.m4 (m4_define_default, m4_fst, m4_map): New.

17729 * doc/autoconf.texi (Programming in M4sh): Add AS_MKDIR_P.
17730 (Limitations of Usual Tools): Add mkdir section.
17732 * lib/m4sugar/m4sh.m4 (_AS_MKDIR_P_PREPARE): New macro.
17733 (AS_MKDIR_P): Require it. Use mkdir -p if available, falling
17734 back on AS_DIRNAME to compute prefixes otherwise; this is
17735 roughly what mkinstalldirs does. That way, we need not have
17736 our own filename disassembler. The old disassembler did not
17737 work with Solaris 8 dtksh, which is ksh Version M-12/28/93d.
17739 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP):
17740 Create at_test_all by a series of assignments,
17741 not by a single assignment of a long string. The latter causes ksh
17742 version 11/16/88g to silently misbehave on OpenServer 5.0.6a,
17743 presumably because of a buffer overrun.
17745 2002-03-14 Paul Eggert <eggert@twinsun.com>
17747 * lib/autotest/general.m4 (at_times_skip):
17748 Renamed from at_times. Now a boolean.
17749 ksh93 Version M-12/28/93d doesn't like 'x=times; $x'; it
17750 says 'times: not found'.
17752 2002-03-14 Akim Demaille <akim@epita.fr>
17754 * bin/autoreconf.in (&study_gettextize): New.
17755 (&autoreconf): Handle newest gettextize.
17756 Rerun aclocal if needed.
17757 Suggested by Andreas Schwab.
17759 2002-03-13 Akim Demaille <akim@epita.fr>

17765 * doc/autoconf.texi (Header Portability): New.
17766 Add information about stdint.h and inttypes.h from Paul Eggert.
17768 2002-03-13 Akim Demaille <akim@epita.fr>
17770 * doc/autoconf.texi (Limitations of Usual Tools): Some about `cp
17774 2002-03-12 Akim Demaille <akim@epita.fr>

17779 2002-03-11 Andreas Schwab <schwab@suse.de>
17781 * configure.ac: Explicitly check for EMACS since AM_PATH_LISPDIR
17782 does not do it if --with-lispdir is given.

17791 subdirectory should exist.
17793 2002-03-08 Akim Demaille <akim@epita.fr>
17795 * Makefile.am (AUTOMAKE_OPTIONS): 1.6.
17797 2002-03-08 Akim Demaille <akim@epita.fr>
17799 * bin/autom4te.in (&handle_m4): Do not foreach with `$_' as it
17800 aliases the actual variables, and modifications of the former
17803 2002-03-08 Akim Demaille <akim@epita.fr>
17805 * bin/autom4te.in (&handle_m4): Protect us from corrupted file
17806 because of C-c: have m4 output in tmp files, then mv them.
17808 2002-03-08 Akim Demaille <akim@epita.fr>

17827 2002-03-04 Akim Demaille <akim@epita.fr>
17829 * doc/autoconf.texi (AC_LIBOBJ vs. LIBOBJS): New.
17830 * lib/autoconf/general.m4 (AC_INIT): More informative error
17831 message for LIBOBJ.
17833 2002-03-04 Akim Demaille <akim@epita.fr>
17835 * lib/freeze.mk ($(build_libdir)/m4sugar/version.m4): New, for
17838 2002-03-04 Akim Demaille <akim@epita.fr>
17840 * doc/autoconf.texi (Transforming Names): Equality between target
17841 and host is irrelevant.
17842 (Specifying Names, Canonicalizing): Remove all references to the
17843 backward compatibility hooks. Rather, collect them all into...
17844 (Hosts and Cross-Compilation): this new section.
17845 * doc/install.texi (System Type): Ditto.
17846 * lib/autoconf/general.m4 (AC_CANONICAL_HOST): Explicitly state
17847 that `--host' implies cross-compilation.
17849 2002-03-04 Akim Demaille <akim@epita.fr>
17851 * doc/autoconf.texi (Evaluation Macros): New.
17852 * lib/m4sugar/m4sugar.m4 (m4_lquote): Remove, it is totally
17854 (_m4_foreach): Define the variant with immediate evaluation so
17855 that it contains exactly the items, not an expression which
17856 evaluation is the current item.
17857 (m4_re_string, m4_re_word): Don't over quote them.
17859 2002-03-04 Akim Demaille <akim@epita.fr>
17861 Instead of having stacking `shift's evaluated at the end, let
17862 `foreach' loops immediately evaluate them.
17864 * lib/m4sugar/m4sugar.m4 (m4_quote, m4_dquote): Use $@ rather than
17865 $*. This is the n-th time I change my mind, but hopefully this is
17868 (m4_text_wrap): Use m4_foreach, which is finally correct _and_
17870 (m4_foreach_quoted, m4_car_quoted, _m4_foreach_quoted): Remove, as
17871 it was only a hack for m4_text_wrap.
17872 (m4_car2): Remove, replaced by...
17874 (_m4_foreach): Adjust.
17875 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Adjust, and use
17876 m4_bpatsubst for clarification.

17928 AC_PREFIX_PROGRAM fails with dashed program names
17930 * lib/autoconf/general.m4 (AC_PREFIX_PROGRAM): Just use a fresh

17963 * tests/semantics.at (AC_CHECK_SIZEOF): Check non-GCC
17964 cross-compilers, too. This undoes some of the most recent change
17967 2002-02-05 Akim Demaille <akim@epita.fr>
17969 * tests/Makefile.am (check_SCRIPTS): Use it, instead of WRAPPERS,

17992 optional are the sum of the previous files on the command line'.
17993 Also, pass `--reload-state=' on them, so...
17994 (handle_m4): don't.
17995 * lib/autom4te.in (Autotest, Autoconf): Rely on M4sh.
17996 (M4sh): Rely on M4sugar.
17997 (Autotest, M4sh, M4sugar): Use frozen files.

18027 Reported by Alexandre Duret-Lutz and Larry Schmitt.
18029 2002-01-28 Akim Demaille <akim@epita.fr>
18031 * doc/autoconf.texi (Writing testsuite.at): AT_CLEANUP no longer
18034 2002-01-28 Akim Demaille <akim@epita.fr>
18036 * lib/autotest/general.m4 (AT_INIT): Don't be ridiculous: adjust
18037 AUTOTEST_PATH *after* it was set.
18038 Don't put `.' in the PATH: the user should be precise and `./' if
18039 needed. In addition, given that the test suite does some `cd', if
18040 `.' is in the path, the `tested programs' sections will report
18041 programs found in the test suite's directory, while during the
18042 tests (performed in their own directory), these programs are no
18043 longer visible. In other words, the results is confusing and
18045 * tests/m4sh.at: Adjust: don't rely on `.' being in the PATH.

18096 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Initialize

18115 EXTRA_DIST it since its a source.

18120 of PACKAGE_NAME, PACKAGE_TARNAME, PACKAGE_VERSION, PACKAGE_STRING,
18121 and PACKAGE_BUGREPORT from here...
18122 (_AC_INIT_DEFAULTS): to here, since it is unrelated to the

18126 (AT_INIT): No longer catch `^PACKAGE_(BUGREPORT|STRING)$'.
18127 * tests/tools.at (autoheader): Adjust.
18128 * tests/atspecific.m4 (AT_CHECK_DEFINES): Adjust.
18130 2002-01-06 Akim Demaille <akim@epita.fr>
18132 * bin/autoscan.in (scan_file): Use `&used'.
18134 2002-01-03 Akim Demaille <akim@epita.fr>
18136 * doc/autoconf.texi (Output): Improved wording regarding use of
18140 2001-12-18 Kevin Ryde <user42@zip.com.au>
18142 * doc/autoconf.texi (Function Portability): Add notes on sscanf
18143 sometimes needing writable input.
18145 2001-12-17 Jim Meyering <meyering@lucent.com>
18147 * doc/autoconf.texi (New Macros): Tweak wording.
18149 2001-12-14 Akim Demaille <akim@epita.fr>
18151 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): We cleaning up the
18152 trailing files, don't apply `-rf' to files which might not be
18153 created by configure (core, core.*, and *.core), but just `rm -f'.
18154 Suggested by Jonathan Kamens.
18156 2001-12-14 Aaron M. Ucko <amu@alum.mit.edu>
18158 * lib/autoconf/general.m4: Avoid duplicates in `$ac_configure_args'.
18160 2001-12-14 Akim Demaille <akim@epita.fr>
18162 * Makefile.am (MAINTAINERCLEANFILES): Remove configure.
18164 2001-12-13 Peter Eisentraut <peter_e@gmx.net>
18166 * lib/autoconf/status.m4 (_AC_SRCPATHS): Rename buildpath to
18167 abs_builddir, top_buildpath to abs_top_builddir, srcpath to
18168 abs_srcdir, top_srcpath to abs_top_srcdir.
18169 (_AC_OUTPUT_FILES): Adjust.
18170 * NEWS, doc/autoconf.texi, lib/autoconf/autotest.m4,
18171 * tests/atspecific.m4, tests/autoreconf.in, tests/tools.at,
18172 * tests/wrappl.in, tests/wrapsh.in: Adjust.
18174 2001-12-12 Steven G. Johnson <stevenj@alum.mit.edu>
18176 * lib/autoconf/fortran.m4 (_AC_PROG_F77_V_OUTPUT): Fix failed
18177 C/Fortran linking on HP/UX, by extracting the Fortran library
18178 search path from the LPATH line in the $F77 -v output.
18180 2001-12-12 Kevin Ryde <user42@zip.com.au>
18182 * doc/autoconf.texi (File Descriptors): Use a clearer layout for the
18183 forbidden file descriptors table.
18185 2001-11-26 Akim Demaille <akim@epita.fr>
18187 * bin/autoscan.in (%c_keywords): Build it at top level.
18188 Map to 1 in order to simplify its uses.
18190 2001-11-26 Akim Demaille <akim@epita.fr>
18192 * bin/autoscan.in (&scan_c_file, &scan_sh_file, &scan_makefile):
18193 Remove $filepath, useless.
18194 (&scan_makefile): Don't remove the $(FOO), ${FOO} and @FOO@
18195 variables, they are really part of the tokens.
18196 Split the input line on spaces and then look for tokens.
18197 Now autoscan ceases to ask for AC_PROG_LEX for the package Bison
18198 because of `lex$U.$(OBJEXT)'.
18199 (&scan_files): Use "@list" instead of join.
18200 * doc/Makefile.am (CLEANFILES): Add *.fns.
18202 2001-11-26 Akim Demaille <akim@epita.fr>
18204 * tests/autoreconf.in, tests/autom4te.in, tests/autoupdate.in:
18205 Remove, replaced by...
18206 * tests/wrappl.in: Be common for all the Perl executables.
18207 In particular autoscan and autoheader want -I.
18208 * configure.ac: Adjust.
18209 * lib/autoscan/headers: errno.h is portable.
18211 2001-11-26 Akim Demaille <akim@epita.fr>
18213 * bin/autoscan.in (used): New.
18216 2001-11-26 Akim Demaille <akim@epita.fr>
18218 * bin/autoscan.in (&scan_c_file): Better parsing of CPP
18220 (&scan_sh_file): Remove a duplicate pattern.
18221 (&check_configure_ac): Use long options.
18222 * lib/autoscan/headers (alloca.h): Check with AC_FUNC_ALLOCA.
18224 2001-11-26 Akim Demaille <akim@epita.fr>
18226 * bin/autoscan.in (scan_c_file): Fix the handling of C comments.
18227 Before, having a line containing the opening of a multi line
18228 comment made the whole line be ignored.
18230 2001-11-26 Akim Demaille <akim@epita.fr>
18232 * doc/autoconf.texi (Using an Autotest Test Suite): New.
18233 (testsuite Scripts): Be one of its subsection.
18234 (Autotest Logs): New.
18236 2001-11-26 Akim Demaille <akim@epita.fr>
18238 Test groups are now run two directories deeper.
18240 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Replace srcdir,
18241 top_srcdir and top_builddir with at_srcdir, at_top_srcdir and
18243 * lib/autotest/general.m4 (AT_INIT): Compute srcdir,
18244 top_srcdir, builddir and top_builddir.
18245 Use `at_*dir' relatively to the directory containing the
18246 suite, use `*dir' when relatively to the current group dir.
18248 2001-11-25 Joseph S. Myers <jsm28@cam.ac.uk>
18250 * doc/autoconf.texi, TODO, lib/autoconf/fortran.m4,
18251 lib/autoconf/functions.m4, lib/autoconf/headers.m4,
18252 tests/atgeneral.m4, tests/tools.at, tests/atspecific.m4: Fix
18255 2001-11-22 Alexandre Duret-Lutz <duret_g@epita.fr>
18257 * doc/autoconf.texi (Using System Type): Add an example of `case
18258 $host' usage so people quit using `case $target' everywhere.
18260 2001-11-22 Akim Demaille <akim@epita.fr>
18262 * doc/autoconf.texi (Installation Directory Variables): Englishoes
18263 spotted by Jim Meyering.
18265 2001-11-16 Paul Eggert <eggert@twinsun.com>
18267 This patch implements a `long double' suggestion by Oliver Kiddle.
18269 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C)): Make the array
18270 static, to catch errors if the value isn't known at compile-time
18271 and the compiler supports dynamic arrays. Change its name from
18272 `_array_' to `test_array' to avoid potential name clashes.
18273 (AC_C_LONG_DOUBLE): Make it a compile-time test, not a run-time
18274 test. Do not define HAVE_LONG_DOUBLE if `long double' is no
18275 better than double. Catch a bug in GCC 2.95.2 x86.
18276 * doc/autoconf.texi (C Compiler): Document the above.
18279 2001-11-13 Akim Demaille <akim@epita.fr>
18281 * tests/m4sh.at (LINENO): Protect from autom4te's substitution by
18283 * tests/tools.at: Don't protect dnl, AT_DATA_M4SH does.
18285 2001-11-13 Akim Demaille <akim@epita.fr>
18287 * lib/autotest/general.m4 (AT_INIT): After having run the test
18288 group, go back to the initial directory, not to at_suite_dir.
18290 2001-11-13 Akim Demaille <akim@epita.fr>
18292 * tests/atspecific.m4 (AT_DATA_M4SUGAR, AT_DATA_M4SH)
18293 (AT_DATA_AUTOCONF): Also protect @&t@ from autom4te.
18294 (AT_CHECK_AUTOCONF, AT_CHECK_AUTOHEADER): Pass no --include
18296 (AT_CHECK_CONFIGURE): Use absolute paths.
18297 (_AT_CHECK_AC_MACRO): Create aclocal.m4 with AC_STATE_SAVE in it.
18298 The problem is still the old one: there is no means in M4 (that I
18299 know about) to create a defining macro, because there is no means
18300 to create `$1' etc., therefore, the defining macro ``swallows''
18301 all the arguments meant to the defined macro.
18303 2001-11-13 Akim Demaille <akim@epita.fr>
18305 * tests/atspecific.m4 (AT_DATA_AUTOCONF): New.
18306 (AT_CONFIGURE_AC): Output the definition of AC_STATE_SAVE in
18308 * tests/aclocal.m4: Remove, as it is no longer used.
18310 2001-11-13 Akim Demaille <akim@epita.fr>
18312 * lib/autotest/general.m4: Change `tests?' into `groups?' in
18313 variable names when referring to a single test group, or to
18314 `suite' when referring to the whole test suite.
18315 `at_last_test' is removed: m4 compute at_format itself.
18316 (at_stdout, at_stder1, at_stderr): New variables.
18317 (AT_CHECK): Use them.
18319 2001-11-13 Akim Demaille <akim@epita.fr>
18321 * lib/autotest/general.m4 (AT_INIT): Be sure to put `.', relative,
18323 Create `testsuite.dir/003/run' instead of `testsuite.003'.
18324 Do it as soon as a test fails, don't wait till the end of the test
18326 Don't remove $as_me.[0-9]*, since these files no longer exist.
18328 2001-11-13 Akim Demaille <akim@epita.fr>
18330 * tests/tools.at: Use absolute paths, since we are no longer run
18333 2001-11-13 Akim Demaille <akim@epita.fr>
18335 Now that tests are running in their own private dir, there is no
18336 need to list the files to remove at the end of tests groups.
18338 * lib/autotest/general.m4 (_AT_CLEANUP_FILE, AT_CLEANUP_FILES):
18339 (AT_data_files, at_data_files): Remove.
18340 (AT_CLEANUP, AT_DATA): Simplify.
18342 Remove the group dir if !debug && !failed.
18343 * tests/atspecific.m4: Adjust.
18345 2001-11-13 Akim Demaille <akim@epita.fr>
18347 Start a new layout for Autotest: `testsuite' creates
18348 `testsuite.dir' in which the at-check-line etc. files are to be
18349 found, and `testsuite.dir/003' where the test group 3 is run.
18351 * lib/autotest/general.m4 (AT_INIT): at_tests_dir,
18352 at_check_line_file, at_format, at_test_normalized, at_group_dir
18354 Create the directories.
18355 Use absolute paths for at- files.
18356 (AT_CHECK): Adjust.
18358 2001-11-11 Michael Matz <matz@kde.org>
18360 * m4sugar.m4 (_m4_foreach): Make it linear instead quadratic.
18362 (m4_car): Properly quote arguments.
18364 2001-11-13 Akim Demaille <akim@epita.fr>
18366 * tests/aclocal.m4 (AC_STATE_SAVE): s/LIBOBJS/LIB@&t@OBJS/ to cope
18367 with stricter rules on LIBOBJS.
18369 2001-11-12 Paul Eggert <eggert@twinsun.com>
18371 * lib/autoconf/c.m4 (AC_C_PROTOTYPES): Define __PROTOTYPES too.
18372 * doc/autoconf.texi (C Compiler): AC_C_PROTOTYPES now defines
18375 2001-11-12 Akim Demaille <akim@epita.fr>
18377 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT): Use AC_CHECK_FUNCS.
18379 2001-11-12 Akim Demaille <akim@epita.fr>
18381 * lib/autoconf/c.m4, lib/autoconf/fortran.m4,
18382 * lib/autoconf/functions.m4, lib/autoconf/general.m4,
18383 * lib/autoconf/headers.m4, lib/autoconf/libs.m4,
18384 * lib/autoconf/programs.m4, lib/autoconf/specific.m4,
18385 * lib/autoconf/types.m4: When invoking AC_DEFINE and friends,
18386 specify to what the macro should be defined (typically to 1).
18388 2001-11-12 Akim Demaille <akim@epita.fr>
18390 * lib/autoconf/functions.m4 (AC_FUNC_STRTOD): AC_SUBST POW_LIB.
18393 2001-11-12 Akim Demaille <akim@epita.fr>
18395 * lib/autoconf/programs.m4 (_AC_PROG_LEX_YYTEXT_DECL): Use
18396 AC_TRY_EVAL to run $LEX, not AC_TRY_COMMAND. This validates the
18397 definition used by Automake where LEX is +/- "${missing} lex" and
18398 `missing' itself contains variables.
18400 2001-11-12 Akim Demaille <akim@epita.fr>
18402 * lib/autotest/general.m4 (AT_INIT): Push KILL at the end.
18403 Now that M4sh pushes BODY, the comments were output at the end of
18406 2001-11-08 Akim Demaille <akim@epita.fr>
18408 * bin/autoreconf.in (&autoreconf): Run aclocal before tracing, so
18409 that we can trace macros from aclocal.m4.
18410 Trace AC_PROG_LIBTOOL, not AM_PROG_LIBTOOL, since the latter is
18411 obsoleted, and redirect to the former anyway.
18412 Reported by Ralf Corsepius.
18414 2001-11-08 Akim Demaille <akim@epita.fr>
18416 * bin/autoreconf.in (&autoreconf): AC_CONFIG_SUBIDRS are to be
18417 processed only if present.
18418 * tests/torture.at (Configuring subdirectories): Use autoreconf
18419 instead of successive calls to autoconf.
18420 Add a nonexistent subdirectory to exercise the patch above.
18421 Reported by Ralf Corsepius.
18423 2001-11-08 Kevin Ryde <user42@zip.com.au>
18425 * doc/autoconf.texi (Limitations of Usual Tools): Note HP-UX cc
18426 doesn't accept .S files.
18428 2001-11-07 Akim Demaille <akim@epita.fr>
18430 * lib/m4sugar/m4sugar.m4 (m4_pattern_forbid): Accepts $2.
18431 * lib/autoconf/general.m4 (AC_INTI): Forbid LIBOBJS.
18432 (_AC_LIBOBJ): s/LIBOBJS/LIB@&t@OBJS/.
18433 * bin/autom4te.in (warn_forbidden): New.
18434 (handle_output): Use it.
18435 Read m4_pattern_forbid with messages.
18437 2001-11-05 Akim Demaille <akim@epita.fr>
18439 * bin/autom4te.in (--normalize): Remove.
18440 * lib/autom4te.in: Adjust.
18442 2001-11-05 Akim Demaille <akim@epita.fr>
18444 * tests/Makefile.am (testsuite): Rename this target as...
18445 ($(TESTSUITE)): this.
18448 2001-11-05 Alexandre Duret-Lutz <duret_g@epita.fr>
18450 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): When removing
18451 the --prefix option, also remove it's argument.
18453 2001-11-05 Akim Demaille <akim@epita.fr>
18455 * doc/autoconf.texi (testsuite Invocation): Update.
18456 (Writing testsuite.at): Update.
18458 2001-11-03 Akim Demaille <akim@epita.fr>
18460 * doc/autoconf.texi: s/@code/@command/ where appropriate.
18462 2001-11-03 Akim Demaille <akim@epita.fr>
18464 * lib/Autom4te/General.pm: (&catfile, &canonfile)
18465 (&file_name_is_absolute): New, wrappers around routines from
18467 Use and export them.
18468 (&find_configure_ac): Optionally take a directory where to look at.
18469 * bin/autoreconf.in (&parse_args): Trim the configure.ac part of
18471 Default @ARGV to `.', not find_configure_ac.
18472 (&autoreconf): Argument is a directory.
18473 Trace AC_CONFIG_SUBDIRS and schedule the subdirs for autoreconf'ing.
18474 * doc/autoconf.texi (autoreconf Invocation): Update.
18476 2001-11-03 Akim Demaille <akim@epita.fr>
18478 * lib/Autom4te/General.pm (@export_vars, @export_subs)
18479 (@export_forward_subs): New.
18480 Add basename, dirname, and fileparse.
18482 * bin/autoreconf.in (&autoreconf): Fix call to fileparse.
18483 Don't look for aclocal flags if we already know aclocal is not
18485 Move aclocal.m4t only if it exists.
18486 Reported by Ezra Peisach.
18488 2001-11-03 Akim Demaille <akim@epita.fr>
18490 * bin/autoreconf.in (&parse_args): Work only on the configure.ac
18491 passed on command line, defaulting to ./configure.ac if present.
18492 (&maybe_autoreconf, File::Find): Remove, unused.
18493 (&autoreconf): If autoconf is not used, don't try to trace.
18495 2001-11-02 Akim Demaille <akim@epita.fr>
18497 * configure.ac: Bump to 2.52g.
18499 2001-11-02 Akim Demaille <akim@epita.fr>
18503 2001-11-02 Akim Demaille <akim@epita.fr>
18505 * config/config.guess, config/config.sub, doc/standards.texi:
18506 * config/lispdir.m4: Update from masters.
18507 * configure.ac: Bump to 2.52f.
18509 2001-11-02 Akim Demaille <akim@epita.fr>
18511 * bin/autoreconf.in (&autoreconf): Set `$aclocal_flags' to ''.
18512 Don't run aclocal when aclocal.m4 is not from aclocal.
18514 Don't run libtoolize and gettextize if --install is not given.
18516 2001-11-01 Paul Eggert <eggert@twinsun.com>
18518 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): _AS_CR_PREPARE needs to
18519 be invoked before _AS_LINENO_PREPARE.
18520 (_AS_LINENO_PREPARE): Use as_cr_digits and as_cr_alnum rather
18521 than character ranges.
18523 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Fix NLS before
18524 invoking AS_BASENAME. Set the locale variables to 'C' if
18525 possible, as POSIX requires this to get the traditional
18527 * doc/autoconf.texi (Special Shell Variables): Describe the above.
18529 2001-10-31 Paul Eggert <eggert@twinsun.com>
18531 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): Do not surround body
18532 with {}, as that triggers a bug in Bash 2.05.
18534 (_AS_LINENO_PREPARE): Use Sed rather than
18535 Awk. Fix the sed prepass to work even if there are multiple
18536 instances of $LINENO on the same line. Do not substitute for
18537 other variables like $LINENOT. Do not check file dates; such a
18538 check is unreliable on sufficiently fast machines, and removing
18539 the check makes the code simpler and more reliable. Check for
18540 output and chmod failures.
18542 * doc/autoconf.texi (Special Shell Variables): Document
18545 2001-10-31 Akim Demaille <akim@epita.fr>
18547 * tests/Makefile.am (atconfig): Remove this target, Automake
18550 2001-10-31 Akim Demaille <akim@epita.fr>
18552 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Do not
18553 AC_CONFIG_FILES(atlocal) as it means a file atlocal.in *must* be
18554 provided, while it is optional.
18555 * configure.ac: Adjust.
18557 2001-10-26 Paul Eggert <eggert@twinsun.com>
18559 * NEWS, README, configure.ac, lib/Autom4te/General.pm,
18560 lib/Autom4te/Struct.pm:
18561 Require Perl 5.005_03 instead of just 5.005, as some tests fail
18564 * doc/autoconf.texi (Special Shell Variables): Document some
18565 more LINENO gotchas, particularly with respect to the Awk+Sed hack.
18567 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): New macro.
18568 (_AS_LINENO_PREPARE): Use it instead of shell eval, since
18569 eval $LINENO is not portable in practice.
18571 2001-10-24 Akim Demaille <akim@epita.fr>
18573 * lib/Autom4te/General.pm (backname): New.
18575 2001-10-24 Akim Demaille <akim@epita.fr>
18577 * m4/: Remove, merged into...
18580 2001-10-23 Tim Van Holder <tim.van.holder@pandora.be>
18582 * doc/autoconf.texi (Shellology): Mention the problems with bash
18583 2.05's use of ANSI quoting in its `set' builtin.
18585 2001-10-22 Paul Eggert <eggert@twinsun.com>
18587 * lib/autoconf/functions.m4 (AC_FUNC_STRERROR_R):
18588 Rename ac_cv_func_strerror_r_works to ac_cv_func_strerror_r_char_p,
18589 and rename HAVE_WORKING_STRERROR_R to STRERROR_R_CHAR_P, since
18590 POSIX decided to standardize on the int flavor of strerror_r.
18591 Always do char* test, as there's no reason not to.
18592 Assign to a char* var, to catch strerror_r that returns int*.
18594 * doc/autoconf.texi (Particular Functions):
18595 Document the above changes. Also, document the fact that
18596 AC_FUNC_STRERROR_R defines HAVE_DECL_STRERROR_R.
18598 * NEWS: Mention HAVE_WORKING_STRERROR_R -> STRERROR_R_CHAR_P.
18600 2001-10-20 Akim Demaille <akim@epita.fr>
18602 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): The name of
18603 the executable was missing from the log.
18605 2001-10-20 Akim Demaille <akim@epita.fr>
18607 * lib/Autom4te/General.pm (&update_file): If destination is
18608 unchanged, remove the source.
18609 (&up_to_date_p): Don't be verbose, be debug.
18610 * bin/autoreconf.in: No longer support --m4dir.
18611 (&autoreconf): Display the full path of the configure.ac we are
18613 Trace it only once.
18614 Be sure to honor --force with gettextize.
18615 Always run aclocal.
18616 * doc/autoconf.texi: Adjust.

19087 (Special Shell Variables[PATH_SEPARATOR]): Ditto.
19088 (Special Shell Variables[CDPATH]): Mention that $PATH_SEPRATOR should
19089 be used instead of ':'.
19090 * lib/autotest/general.m4: Replace occurrences of ':' in
19091 AUTOTEST_PATH with $PATH_SEPARATOR at test suite startup.
19093 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
19095 * tests/atgeneral.m4: Add basic support for test ranges (e.g. 7-34) as
19096 arguments. Fixed a typo.
19098 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
19100 * man/Makefile.am (.x.1): Use @PATH_SEPARATOR@, not ':' to set up
19101 $PATH. Also set AUTOM4TE_CFG, so we can process autom4te properly.
19103 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
19105 * bin/autoscan.in: Add 'exec-perl-if-not-run-by-perl'.

19112 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
19114 * lib/Autom4te/XFile.pm (open): Simplified the error message (we
19115 already have $file). Set output files to binary mode (helps avoid
19116 CR issues on DOSish systems).
19118 2001-09-19 Akim Demaille <akim@epita.fr>
19120 * lib/autotest/general.m4: Englishoes.
19121 From Tim Van Holder and Alexey Mahotkin.
19123 2001-09-18 Paul Eggert <eggert@twinsun.com>
19125 * doc/autoconf.texi (Common Shell Constructs): New node,
19126 documenting AS_DIRNAME.
19127 (Limitations of Usual Tools): Refer to it when discussing dirname.
19128 Also, update discussion of POSIX standard to reflect latest draft.
19130 * lib/autoconf/c.m4:
19131 (AC_LANG_INT_SAVE(C)): Also support negative values, down to LONG_MIN.
19133 * lib/autoconf/general.m4 (_AC_COMPUTE_INT_COMPILE):
19134 Do not pass a first argument with leading '-'
19135 to expr, by parenthesizing initial integers that might be negative.
19137 * doc/autoconf.texi (Particular Functions): AC_FUNC_GETPGRP
19138 now merely checks whether it is an error to pass an argument
19141 * lib/autoconf/functions.m4 (_AC_FUNC_GETPGRP_TEST): Remove.
19142 (AC_FUNC_GETPGRP): Don't bother with a runtime test. Just check
19143 whether it is a (compile-time) error to pass an argument to
19144 getpgrp. This simpler test supports the revised documentation,
19145 and is all that AC_FUNC_GETPGRP's users really need.
19147 2001-09-18 Akim Demaille <akim@epita.fr>
19149 * doc/autoconf.texi (Limitations of Make) <$<>: New.

19159 * tests/m4sh.at: Ensure that AS_DIRNAME handles '/', '//' and '///'
19161 Add test for AS_BASENAME.
19162 * lib/m4sugar/m4sh.m4: Fix AS_BASENAME so that it passes the previous
19163 added test. It now correctly handles /1/2/3/, returning '3' not ''.
19164 Added AS_BASENAME_SED to make the interface the same as AS_DIRNAME.
19165 * tests/base.at: Fixed the expected responses. The old ones were
19167 * lib/autoconf/general.m4: Fixed AC_PREFIX_PROGRAM, it now behaves as
19168 the documentation claims it should (and how it behaved in 2.13).
19170 2001-09-18 Akim Demaille <akim@epita.fr>
19172 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): No INIT-CMDS in
19173 the AC_CONFIG_COMMANDS invocation.
19174 This also solves the name clash problems.
19175 Don't set the package's ID.
19176 * lib/m4sugar/Makefile.am (version.m4): Revamp.
19177 No longer to be shipped.
19178 (version.in): Remove.

19181 Use `m4_PACKAGE_STRING'.
19182 * lib/autotest/general.m4 (AT_INIT): N-th signature change: now
19183 the only optional argument is the name of the test suite.
19184 Expect `package.m4' to define the package signature.
19185 * lib/autom4te.in (Autotest): Add `package.m4?'.
19186 * tests/Makefile.am (package.m4): New.
19187 * tests/suite.at: ifnames is a victim.
19189 2001-09-18 Akim Demaille <akim@epita.fr>
19191 * lib/autom4te.in (Autoconf): Preselect AM_CONDITIONAL,
19192 AC_LIBSOURCE, AC_CONFIG_FILES.
19193 * lib/autotest/general.m4 (AT_INIT): Don't abort when a tested
19194 program version string doesn't match the package's.
19195 * lib/autoconf/general.m4 (AC_CACHE_VAL): Reestablish the space

19206 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):
19207 Always include <stdio.h> and <stdlib.h>. Evaluate
19208 the expression in an extra function before these includes. Call
19209 fprintf "%d" only after ensuring the argument is of type 'int'.
19210 Reported by Wayne Chapeskie <waynec@spinnaker.com>.
19212 2001-09-17 Paul Eggert <eggert@twinsun.com>
19214 Fix bug reported by Paul Townsend on AIX 4.3.3.0 with CFLAGS=-O4
19215 or CFLAGS=-O5. In that case, the linker has a relaxed view of
19216 fatal errors, and AC_CHECK_LIB causes it to include libraries even
19217 when they don't exist.
19219 * lib/autoconf/headers.m4 (AC_HEADER_DIRENT): Use AC_SEARCH_LIBS,
19220 not AC_CHECK_LIB, so that we don't use -ldir or -lx if we don't
19223 * lib/autoconf/specific.m4 (AC_ISC_POSIX): Replace the old, crufty
19224 version with the version used by fileutils 4.1, except use
19225 AC_SEARCH_LIBS, not AC_CHECK_LIB, so that we don't use -lcposix if
19228 * doc/autoconf.texi (AC_ISC_POSIX): Describe new behavior.
19230 2001-09-13 Akim Demaille <akim@epita.fr>

19270 * lib/autotest/general.m4 (AT_INIT): Create and remove
19271 `$as_me.[0-9]+' instead of `debug-[0-9]+.sh', so that multiple
19272 test suites can cohabit.

19276 * tests/mktests.sh: Don't output banners for empty test files.

19385 the maintainer is dumb enough to do that...
19387 * lib/autotest/general.m4 (AT_SETUP, AT_LINE): Demonstrates your
19388 excellence in M4 quotation: consider `__file__' is active.

19555 * lib/autom4te.in (Autoconf): Add `acsite.m4?' and `aclocal.m4?'.

19565 * lib/autotest/general.m4 (AT_INIT): `AUTOTEST_PATH=a:b' gives

19567 * man/Makefile.am: Let help2man rely on PATH instead of trying to
19568 find the executables for it.

19570 * tests/atlocal.in: Remove all the obscure envvar manipulations.
19572 * tests/atspecific.m4, tests/tools.at: Passing --localdir is
19573 indeed related to running the test suite, while passing
19574 --autoconf-dir and others is related to running non installed
19575 Autoconf executables. So don't do that, leave it to...
19576 * tests/autoconf, tests/autoheader, tests/autom4te, tests/autoupdate,
19577 * tests/autoscan: New.
19578 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): Don't

20071 * tests/m4sugar.at (m4_warn): Pass `-f' to autom4te to ensure the

20150 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Guess endianness by grep'ing
20151 magic values from an object file when cross-compiling.
20152 Based on code by Guido Draheim <Guido.Draheim@gmx.de>.
20154 2001-08-10 Akim Demaille <akim@epita.fr>
20156 * bin/autom4te.in (&handle_output): Don't use `grep' with side
20158 Suggested by Russ Allbery.
20160 2001-08-10 Ralf Corsepius <corsepiu@faw.uni-ulm.de>
20162 * lib/autoconf/general.m4 (_AC_OUTPUT_SUBDIRS): Propagate the
20163 current $prefix to the sub-configures.
20165 2001-08-09 Tim Van Holder <tim.van.holder@pandora.be>
20167 * lib/autoconf/lang.m4: Ignore *.xSYM when looking for an executable
20168 extension (needed on BeOS). Reported by Guido van Rossum.
20170 2001-08-09 Akim Demaille <akim@epita.fr>
20172 * bin/autom4te.in ($icache): Load it only if older than autom4te.
20174 2001-08-07 Akim Demaille <akim@epita.fr>
20176 * lib/autotest/general.m4 (AT_INIT): All the `at-*' are to be
20178 (at-setup-line): Huh? Be a variable `at_setup_line', not a file.
20179 No need to remove the files before and after the each test, before
20180 each test and at the end of the suite is enough.
20181 Display only the children `times', not the shell's.
20182 If the test failed or was skipped, at-times is not available.
20184 2001-08-07 Akim Demaille <akim@epita.fr>
20186 Always produce testsuite.log, including when there are no
20187 failures. This helps getting information on skipped tests, and
20188 duration of the tests. Err, implement the latter btw.
20190 * lib/autotest/general.m4 (AT_INIT): Set up fd 6 for the log.
20191 Dump information on the first run of each test.
20192 (AT_CLEANUP): Create `at-times' containing the duration of the
20195 2001-08-07 Akim Demaille <akim@epita.fr>
20197 The use of `dumpstat' revealed that `len' was used although it
20198 should not. m4_text_wrap was using it, but in the Autoconf world
20199 where it is legal. Hence (i) test M4sh in its own world, not
20200 Autoconf's, and (ii), ahem, fix the bug :)
20202 * lib/autotest/general.m4: Be sure the set good quotes, as tracing
20203 does not like `' instead of [].
20204 (AT_INIT): Forbid `^_?AT_'.
20205 And don't output such tokens.
20206 * tests/Makefile.am (CLEANFILES): Add `script', `script.s4g',
20207 `script.as', and `autom4te.cache'.
20208 Remove `empty' and `macro' which are no longer used.
20209 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): New.
20210 * tests/m4sugar.at: Use it.
20211 * lib/m4sugar/m4sugar.m4: Use `m4_len' not `len'.
20213 2001-08-07 Akim Demaille <akim@epita.fr>
20215 * bin/autoconf.in, bin/autoheader.in: --force, -f is a new option.
20217 2001-08-07 Alexandre Duret-Lutz <duret_g@epita.fr>
20219 * bin/autom4te.in (handle_output): Typo in quadrigraph substitution.
20221 2001-08-04 Akim Demaille <akim@epita.fr>
20223 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA, AC_FUNC_ERROR_AT_LINE)
20224 (AC_FUNC_FSEEKO, AC_FUNC_OBSTACK): Use AC_LANG_IFELSE, not
20226 * lib/autoconf/headers.m4 (AC_HEADER_MAJOR): Likewise.
20227 * lib/autoconf/fortran.m4 (_AC_LANG_PROGRAM_C_F77_HOOKS)
20228 (AC_F77_MAIN): Likewise.
20230 2001-08-04 Akim Demaille <akim@epita.fr>
20232 Don't rely on M4sugar outputting the patterns in files, since we
20233 might process the output _without_ running m4, hence without these
20236 * lib/m4sugar/m4sugar.m4 (m4_init): No need for `m4_tmpdir'.
20237 * bin/autom4te.in (@Request::includes): Remove, unused.
20238 (@Request::source): Rename as...
20239 (@Request::input): this.
20240 (@preselect): Add `m4_pattern_forbid' and `m4_pattern_allow'.
20241 (&handle_output): Fetch the patterns from the traces.
20242 `$forbidden' and `$allowed' are constant: use m//o.
20243 (&handle_m4): M4sugar no longer wants `m4_tmpdir'.
20244 (m4_pattern_forbid, m4_pattern_allow): Adjust for tracing only.
20246 2001-08-04 Akim Demaille <akim@epita.fr>
20248 `autoconf && autoheader' is sped up. Now, speed up `autoheader &&
20249 autoconf', i.e., in addition to caching traces, cache the output.
20251 * bin/autom4te.in (Request::cache): Rename as...
20252 (Request::id): this.
20253 ($cache, $icache, $tcache, $ocache): New.
20254 (&handle_m4): Save M4 output in the cache instead of $tmp.
20255 (&handle_output): Adjust.
20256 (&up_to_date_p): Check that the output cache is up to date too.
20257 (top level): Run `&handle_m4' iff force or the cache is invalid.
20258 Run `&handle_output' if the output cache is more recent.
20260 2001-08-04 Akim Demaille <akim@epita.fr>
20262 * bin/autom4te.in ($force): New.
20263 (&parse_args, &print_usage): -f, --force is a new option.
20264 (&handle_output): CPP directives might have spaces after `#'.
20265 (&parse_args): The first file only can be frozen.
20267 2001-08-04 Akim Demaille <akim@epita.fr>
20269 Don't let autom4te compute the `include' traces several times:
20270 first check that the trace cache file is up to date, and then
20271 compare its timestamp with that of the output.
20273 * bin/autom4te.in, bin/autoupdate.in, bin/autoscan.in: Normalize
20274 the preamble. Don't require 5.005 as Autom4te::General does it,
20275 and better yet (use `use', not `require'!).
20276 * lib/Autom4te/Struct.pm: Rename the last occurrences of
20277 Class::Struct as Autom4te::Struct.
20278 * lib/Autom4te/General.pm (File::stat): Use it.
20279 (&mtime): New, export it.
20280 * bin/autom4te.in: Use it.
20281 Declare `$req' is invalid if it is outdated.
20282 Don't declare it valid before saving it if something went wrong.
20284 2001-08-04 Akim Demaille <akim@epita.fr>
20286 Autom4te shall not encode Autoconf data, and preselecting traces
20287 must be proposed to the users.
20289 * bin/autom4te.in (@required_trace): Remove.
20291 (&parse_args, &print_usage): -p, --preselect is a new option.
20292 (&up_to_date_p): Adjust.
20293 * bin/autoconf.in: Preselect some Autoconf macros.
20295 2001-08-04 Akim Demaille <akim@epita.fr>
20297 * tests/tools.at (autoconf --trace: user macros): Check traces on
20298 macros invoked without arguments, and macros invoked with multiple
20301 2001-08-03 Alexandre Duret-Lutz <duret_g@epita.fr>
20303 * bin/autom4te.in (handle_traces): Fix rewriting of traces without
20306 2001-08-03 Akim Demaille <akim@epita.fr>
20308 * bin/autoconf.in ($@): Work around the usual sh bug.
20311 2001-08-03 Akim Demaille <akim@epita.fr>
20313 Clean up the handling of the M4 builtins tracing exception.
20315 * bin/autom4te.in (Request::request): Don't complete M4 builtins
20317 (@m4_builtins): Rename as...
20318 (@m4_builtin): this.
20319 (%m4_builtin_alternate_name): New.
20320 (&parse_args): Complete the trace requests with alternate names.
20321 (&handle_traces): Hence no longer do it here.
20322 (&trace_requests): Remove, unused.

20326 * doc/autoconf.texi (Redefined M4 Macros): Document m4_exit,
20327 m4_if, and m4_wrap.
20329 2001-08-03 Akim Demaille <akim@epita.fr>
20331 * lib/m4sugar/m4sugar.m4 (m4_init): Also forbid `_m4_*' tokens.
20332 (m4_divert_pop): Dump the whole diversion stack when a diversion
20334 * bin/autom4te.in (&handle_output): Remember of the first
20335 occurrence of a possibly undefined macro, not the last.
20336 Complain about the possibly undefined macros in the same order as
20337 the appear in the output.
20338 * lib/autoconf/Makefile.am (autoconf.m4f): List its dependencies.
20339 * tests/tools.at (autoconf: forbidden tokens, basic)
20340 (autoconf: forbidden tokens, exceptions): No longer sort
20341 autoconf's stderr, as it is now deterministic.
20342 Check that `dnl' is caught.
20344 2001-08-01 Akim Demaille <akim@epita.fr>
20346 * configure.ac: Bump to 2.52c.

20363 * bin/autoconf.in, bin/autom4te.in, bin/autoupdate.in: Remove your
20364 `END', as `Autom4te::General::END' will be triggered.
20365 * bin/autoupdate.in, bin/autoscan.in: Improve error messages accuracy.
20366 * bin/autoupdate.in (File::Compare, File::Copy): Use them instead of
20367 system to run `mv', `rm', and `cmp'.
