973 The test suite did not cover this bug because the code was not

976 /dev/null so we couldn't see its error message).

1102 for this feature.
1103 (Keywords and ranges): Add test for missing -k argument.
1104 * NEWS: Document this.
1105 * doc/autoconf.texi (testsuite Invocation): Likewise.

1120 2008-01-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1122 Fix --help=recursive with multiple AC_CONFIG_SUBDIRS.
1123 * lib/autoconf/general.m4 (_AC_INIT_HELP): If, for recursive help
1124 mode, we change to the source directory, also set $ac_pwd so we
1125 do not go back to the build tree for the next config subdir.

1127 config subdirs on the top level.
1129 Fix parallel `maintainer-check'.

1188 * tests/local.at (AT_CHECK_M4): Cater to new m4 error message.
1190 Optimize AC_REQUIRE.
1191 * lib/m4sugar/m4sugar.m4 (m4_expansion_stack_push, _m4_defun_pro)
1192 (_m4_defun_pro_outer, _m4_defun_epi, _m4_defun_epi_outer)
1193 (m4_require): Avoid extra macro calls.
1195 2007-12-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1197 * tests/torture.at (srcdir): Fix quoting.
1199 Do not pass top_srcdir to configure scripts in testsuite.
1200 * tests/autotest.at (srcdir propagation): Copy install-sh to
1201 source tree.
1202 (my only test): Drop setting of `top_srcdir'.
1203 * tests/base.at (Input/Output): Likewise.
1204 * tests/local.at (AT_CONFIGURE_AC): Copy install-sh,
1205 config.guess, and config.sub to test source tree.

1215 if `pwd` contains whitespace.
1217 Quote $abs_top_srcdir in tests.
1218 * tests/local.at (AT_CHECK_PERL_SYNTAX): Likewise.
1219 * tests/tools.at (Syntax of the shell scripts): Likewise.
1221 * tests/m4sh.at (LINENO): Quote $0.
1223 Fix testsuite program wrapper for whitespace in `pwd`.
1224 The problem here is that the usual mantra is that command
1225 variables can contain arguments, thus we cannot just escape
1226 $AUTOCONF, $AUTOM4TE etc. The compromise is to put the
1227 $top_builddir/tests directory early in $PATH, so that the
1228 wrappers are found by their plain name.
1229 * tests/wrapper.as: Put $testdir early in $PATH.
1230 (AUTOCONF, AUTOHEADER, AUTOM4TE): Set to plain command names.
1232 Proper config.status --file/--header and $srcdir escaping.
1233 * lib/autoconf/status.m4 (_AC_OUTPUT_MAIN_LOOP): Quote special
1234 characters in $ac_file_inputs.

1240 Fix Autotest for whitespace in `pwd`.

1243 Quote $at_group_dir.
1244 * tests/autotest.at (whitespace in absolute testdir): New test.
1246 * lib/autom4te.in: Quote @datadir@.
1248 Proper file name escaping in Autoconf programs and Perl modules.
1249 This includes escaping of characters special to the shell
1250 as well as special to Perl, e.g., leading `<' or `>'.
1251 For example, when $file starts with `>', `open ">$file"'
1252 wrongly tries to append to a different file.
1253 * bin/autoconf.as: Fix quoting for autom4te options.
1254 * lib/Autom4te/General.pm (shell_quote): New function, taken
1255 from coreutils, written by Jim Meyering.
1256 (mktmpdir): Use it.
1257 * bin/autom4te.in (files_to_options, handle_m4): Use shell_quote
1258 and open_quote.
1259 * bin/autoreconf.in (parse_args): Likewise.
1260 * bin/autoscan.in (main): Likewise.
1261 * bin/autoupdate.in (main): Likewise.
1262 * bin/autoheader.in: Likewise, fixing old insufficient escaping.
1263 * bin/ifnames.in: Likewise, XFile usage fixes.
1264 * tests/tools.at (autom4te and whitespace in file names): Extend
1265 test. Test twice, with special characters allowed on w32, and the
1266 rest. Test leading and trailing whitespace, for `open_quote'.
1267 (autotools and whitespace in file names): New, analogous test.
1268 Reported by Paul Eggert and Benoit Sigoure, additional suggestions
1269 by Russ Allbery and Eric Blake.
1271 Sync from Automake.
1272 * lib/Autom4te/Channels.pm, lib/Autom4te/Configure_ac.pm,

1274 * lib/Autom4te/FileUtils.pm (open_quote): New function.
1275 (update_file, contents): Use it.
1277 * Makefile.am (autom4te-update): Rewrite for git.
1279 2007-12-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1281 * doc/autoconf.texi (autom4te Invocation, Autom4te Cache): Fix typos.
1283 Fix copyright years.

1293 When using older automake, don't downgrade build-aux/texinfo.tex.
1294 * configure.ac (AM_INIT_AUTOMAKE): Add no-texinfo.tex option.
1295 * doc/Makefile.am (TEXINFO_TEX): Add.
1297 2007-11-27 Paul Eggert <eggert@cs.ucla.edu>
1299 Fix AC_C_BIGENDIAN bug caused by new awk method of substitution.
1300 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Don't comment out the
1301 #undef as this runs afoul of our new way of creating config.h.
1302 Problem reported by Jim Meyering in
1303 <http://lists.gnu.org/archive/html/autoconf-patches/2007-11/msg00164.html>.
1305 2007-11-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1307 Fix autom4te for unusual characters in input file names.
1308 * bin/autom4te.in (files_to_options): Quote active characters
1309 for the shell.
1310 * tests/tools.at (autom4te and white space in file names):
1311 New test.
1313 * doc/autoconf.texi (Limitations of Usual Tools) <awk>:
1314 Document that Tru64 awk always splits $0.
1316 2007-11-24 Stepan Kasal <kasal@ucw.cz>
1318 * lib/autotest/general.m4 (AT_INIT): Do not extract the
1319 `#AT_STOP_...' line at the end of each test.
1321 2007-11-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1323 * lib/autotest/general.m4 (AT_INIT): For awk line number
1324 extraction script, ensure `$at_group' has a defined value
1325 even for the empty set, and properly quote its usage inside
1326 the awk script.
1328 2007-11-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1330 * doc/autoconf.texi (Shell Functions): New chapter. Document
1331 IRIX sh $0 issue in functions, move content from ...
1332 (Portable Shell): ... here.
1333 (Shell Script Compiler): Note that shell functions are not
1334 totally unportable any more.
1336 2007-11-22 Stepan Kasal <kasal@ucw.cz>
1337 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

1345 Fix quoting.
1347 2007-11-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1349 Fix IRIX testsuite debugging failures: $0 in functions.
1350 * lib/autotest/general.m4 (AT_INIT) <at_func_create_debugging_script>:
1351 Do not use $0 inside a function, as IRIX sh will set that to the
1352 function name rather than the script invocation name.
1354 2007-11-19 Paolo Bonzini <bonzini@gnu.org>
1355 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1357 * lib/autotest/general.m4 (at_func_test): Use cached line numbers
1358 to extract test scripts.
1359 (AT_INIT): Extract and cache test script line numbers.
1361 2007-11-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1363 * lib/autotest/general.m4: Revert 2007-11-15 patch and
1364 subsequent fixups; the awk -> here-document conversion trashes
1365 performance too much with AIX sh.
1367 2007-11-18 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1369 * tests/local.at: Do not test m4, perl with AT_TESTED.
1371 Diagnose and guard against write errors dealing with config.status.
1372 The general idea is this: all write failures from `configure'
1373 writing `config.status' are indicated by $ac_write_error, which
1374 is only checked at the end. This is safe because config.status
1375 code is not executed before the file is complete. Other write
1376 failures, be they inside config.status, or in sub shell/awk
1377 scripts spawned from configure or config.status, typically need
1378 earlier checking, as their results are used right afterwards.
1379 * lib/autoconf/status.m4 (AC_OUTPUT): Initialize `ac_write_fail'
1380 before writing config.status, check afterwards.
1381 (_AC_OUTPUT_FILES_PREPARE, _AC_OUTPUT_FILE)
1382 (_AC_OUTPUT_HEADERS_PREPARE,_AC_OUTPUT_CONFIG_STATUS):
1383 Set `ac_write_error' for write failures to config.status. Barf
1384 upon write failures to temporary files.
1385 Adjust note about closing and reopening the here-document.
1386 (_AC_OUTPUT_HEADER, _AC_OUTPUT_LINK, _AC_OUTPUT_COMMAND)
1387 (_AC_OUTPUT_MAIN_LOOP): Likewise, adjust note about closing and
1388 reopening the here-document.
1389 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
1390 Ensure `ac_write_error' does not escape into config.status.
1391 Also, add a couple of code paths not yet exercised in the test
1392 suite: a config file with input from stdin, and a config header
1393 output to stdout.
1394 Suggestion for catching write errors by Bruno Haible.
1396 2007-11-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1398 Avoid error with Tru64 awk and testsuite lines with many words.
1399 * lib/autotest/general.m4 (AT_INIT): In the awk script that
1400 reads the testsuite, set the field separator to an unusual value,
1401 in order to not run over the limit of 199 fields. Tru64 4.0D awk
1402 even splits the input if $i, i>0, was never accessed in the script.
1404 Revert 2007-10-17 change.
1405 * TODO: Multiline args in config files and headers mean something
1406 different and are not fixed, see

1412 2007-11-16 Stepan Kasal <kasal@ucw.cz>
1414 AC_*_TOOL does not canonicalize the prefix
1415 * doc/autoconf.texi (Generic Programs): Do not say that

1470 Redirect just once, not for each echo statement.
1471 Use $@, not literal "expr".
1473 2007-11-13 Paul Eggert <eggert@cs.ucla.edu>
1475 Don't worry about preprocessor when testing long long.
1476 See: http://lists.gnu.org/archive/html/bug-gnulib/2007-11/msg00075.html
1477 * doc/autoconf.texi (Preprocessor Arithmetic): New section.
1478 (AC_TYPE_LONG_LONG_INT, AC_TYPE_UNSIGNED_LONG_LONG_INT):
1479 These no longer check for preprocessor flaws.
1480 * lib/autoconf/types.m4 (_AC_TYPE_LONG_LONG_SNIPPET):
1481 Do not check for preprocessor flaws.
1483 2007-11-13 Jim Meyering <meyering@redhat.com>
1485 Adapt dependencies, now that a version change doesn't modify configure.ac
1486 * GNUmakefile: Remove "make clean" kludge.
1487 * lib/m4sugar/Makefile.am (version.m4): Depend on Makefile, not
1488 configure.ac.
1489 Don't redirect directly to target.
1490 Use $@, not literal "version.m4".
1492 2007-11-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1494 * doc/autoconf.texi (Making testsuite Scripts): Document
1495 ":;{" shorthand as in previous patch.
1497 2007-11-12 Paul Eggert <eggert@cs.ucla.edu>
1499 * doc/autoconf.texi (Limitations of Builtins): Document problem
1500 with { ... } a bit more clearly. Suggest ":;{" as a shorthand
1501 for the workaround.
1502 * lib/m4sugar/Makefile.am (version.m4): Detect 'echo' failure.
1503 Use ":;{" shorthand.
1504 * tests/Makefile.am ($(srcdir)/package.m4): Likewise.
1506 2007-11-12 Jim Meyering <meyering@redhat.com>
1508 Add more non-srcdir build support.
1509 * GNUmakefile (dummy): Split a long line.
1510 Add -v option to autoreconf invocation.
1512 Remove the autoreconf-provided INSTALL, so that we regenerate it.
1513 * GNUmakefile (dummy): Remove INSTALL.
1515 Remove racy commands to build scripts in bin/ and tests/.
1516 * man/Makefile.am (.x.1): Now that scripts in bin/ and tests/
1517 are guaranteed to be built, remove the rules that tried to build
1518 them. Before, with a parallel build, these rules could lead to
1519 two processes writing tests/wrapper.in concurrently.
1521 Build in man/ only *after* building in bin/ and tests/.
1522 * Makefile.am (SUBDIRS): The man-page-creation process runs $(MAKE)
1523 in both bin/ and tests/.
1525 Accommodate non-srcdir build-from-checkout.
1526 * build-aux/git-version-gen: Require an additional parameter: $srcdir.
1527 Use git's --git-dir=$srcdir/.git option.
1528 Add quotes, in case tarball_version_file contains shell meta-characters.
1529 * GNUmakefile (_curr-ver): Pass $(srcdir) to git-version-gen.
1530 * configure.ac: Pass "." to git-version-gen.
1532 Avoid spurious test failures due to version skew.
1533 * GNUmakefile (dummy): Run $(MAKE) clean after autoreconf -i.
1535 2007-11-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1537 Avoid warnings about conftest.dSYM directories on Mac OS X Leopard.
1538 * lib/autoconf/general.m4 (_AC_LINK_IFELSE, _AC_RUN_IFELSE):
1539 Remove conftest.dSYM directory.
1540 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT)
1541 (_AC_LANG_PROGRAM_C_, _AC_FC_MAIN, __AC_FC_NAME_MANGLING):
1542 Remove `conftest.*' recursively.
1543 * lib/autoconf/lang.m4 (AC_LINK_IFELSE): Likewise.
1544 * lib/autoconf/specific.m4 (_AC_SYS_LARGEFILE_MACRO_VALUE):
1545 Likewise.
1546 (_AC_COMPILER_OBJEXT_REJECT): Reject *.dSYM.
1547 * THANKS: Update.
1548 Report and analysis by Jeff Squyres and Peter O'Gorman.
1550 2007-11-12 Benoit Sigoure <tsuna@lrde.epita.fr>
1552 Fix typos in variable names.
1553 * tests/semantics.at (test for AC_CHECK_LIB): s/at_m/ac_m/.
1555 2007-11-11 Benoit Sigoure <tsuna@lrde.epita.fr>
1557 Document that $((expression)) is not portable.
1558 * doc/autoconf.texi (Shell Substitutions): Here.
1560 2007-11-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1562 Ignore configure --help* errors due to LINENO-impaired shells.
1563 * tests/torture.at (Configuring subdirectories, Deep Package):
1564 In the --help* tests in read-only trees, make `.' temporarily
1565 writable again for the `stderr' file, and ignore errors due to
1566 the attempt to write configure.lineno.
1567 Report by Patrick Welche.
1569 2007-11-10 Jim Meyering <meyering@redhat.com>
1571 Generate package.m4 in build-dir, not srcdir.
1572 * tests/Makefile.am (package.m4): Adjust target.
1573 Don't redirect directly to $@.
1574 (CLEANFILES): Add package.m4.
1575 ($(TESTSUITE)): Depend on just-built package.m4, not the one
1576 in $(srcdir).
1577 When running $(AUTOTEST), search "." before searching $(srcdir).
1579 Avoid a race condition that would make parallel "distclean" fail.
1580 * tests/Makefile.am (distclean-generic): Replace the default,
1581 automake-provided rule with an identical one, but with an additional
1582 dependency on distclean-local. Simply adding the dependency would
1583 cause automake not to emit the rule at all.
1584 * BUGS: Building with -jN works, now.
1586 Distribute git-version-gen.
1587 * Makefile.am (EXTRA_DIST): Add build-aux/git-version-gen,
1588 since GNUmakefile is distributed, and requires it for dist* rules.
1590 Remove two more generated files from version control.
1591 * INSTALL: Remove generated file.
1592 * lib/autoscan/autoscan.list: Remove generated file.
1594 2007-11-09 Paul Eggert <eggert@cs.ucla.edu>
1596 * GNUmakefile (PATH): Remove stray apostrophes; they become
1597 part of PATH, which isn't wanted here.
1599 2007-11-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1601 New config files output variable `top_build_prefix'.
1602 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Substitute
1603 `top_build_prefix'.
1604 * doc/autoconf.texi (Preset Output Variables): Document it.
1605 * NEWS: Update.
1606 Report by Bob Friesenhahn.
1608 Avoid expr for arithmetic evaluation if the shell accepts $((...)).
1609 * lib/autotest/general.m4 (AT_INIT) <at_func_arith>: New
1610 function, to parametrize arithmetic with expr vs. the shell.
1611 Use it where possible.
1612 Suggestion by Benoit Sigoure.
1614 2007-11-03 Benoit Sigoure <tsuna@lrde.epita.fr>
1616 Adjust the documentation of autotest WRT atlocal.
1617 * doc/autoconf.texi (Making testsuite Scripts): It is not necessary,
1618 when using Automake, to write a rule to produce atlocal, since it's
1619 an AC_CONFIG_FILES. Mention that atlocal.in needs to be
1620 distributed, not atconfig.in.
1622 2007-11-04 Eric Blake <ebb9@byu.net>
1624 Update list information.
1625 * README: Mention new autoconf-commit list.
1626 * doc/autoconf.texi (Introduction): Mention autoconf-commit list.
1628 2007-11-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1630 * lib/autoconf/functions.m4 (_AC_FUNC_MALLOC_IF): Fix comment typo.
1632 * lib/m4sugar/Makefile.am (version.m4): Another bash bug workaround.
1634 * build-aux/.gitignore: Ignore mkinstalldirs.
1636 * doc/autoconf.texi (autoreconf Invocation): Fix an underfull line.
1638 2007-11-03 Jim Meyering <meyering@redhat.com>
1640 s/-/./ in snapshot version string: 2.61a-256-8b556 -> 2.61a.256-8b556
1641 * build-aux/git-version-gen: This syncs from coreutils.
1643 Adjust the build procedure so "make check" works reliably.
1644 * README-hacking: Include an extra step between "make" and
1645 "make check" to ensure that the latter passes.
1647 Use just-built tools, when possible.
1648 * GNUmakefile (PATH): Set and export here, ...
1649 (dummy): ... rather than here.
1651 2007-11-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1652 and Andreas Schwab <schwab@suse.de>
1654 * tests/Makefile.am ($(srcdir)/package.m4): Work around bash
1655 exit status bug.
1657 2007-11-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1659 * configure.ac (AC_PREREQ): Require version 2.60, for
1660 AC_PROG_SED, AC_PROG_GREP.
1662 2007-11-02 Benoit Sigoure <tsuna@lrde.epita.fr>
1663 and Jim Meyering <meyering@redhat.com>
1664 and Andreas Schwab <schwab@suse.de>
1665 and Eric Blake <ebb9@byu.net>
1667 Document a bug in GNU Bash with compound commands and redirections.
1668 * doc/autoconf.texi (Limitations of Builtins): Mention that GNU
1669 Bash doesn't properly set $? when `{ ... } >/bad' fails, and give
1670 workaround.
1672 2007-11-03 Eric Blake <ebb9@byu.net>
1674 Support m4 1.4.5 in testsuite.
1675 * tests/torture.at (Define a newline): Exclude line numbers in
1676 error message.
1677 Reported by Ralf Wildenhues.
1679 2007-11-03 Jim Meyering <meyering@redhat.com>
1681 Remove automake-provided files from version control.

1683 * build-aux/install-sh: Remove file.
1684 * build-aux/missing: Remove file.
1685 * build-aux/mdate-sh: Remove file.
1686 * build-aux/.gitignore: New file.
1687 Suggestion from Ralf Wildenhues.
1689 2007-11-03 Eric Blake <ebb9@byu.net>
1691 Adjust version comparison to account for git snapshot numbers.
1692 * lib/m4sugar/m4sugar.m4 (_m4_version_unletter): Also treat - as a
1693 component separator.
1694 * doc/autoconf.texi (Number processing Macros)
1695 <m4_version_compare>: Document this change.
1696 * tests/m4sugar.at (m4@&t@_version_compare): Test it.
1698 2007-10-30 Bruno Haible <bruno@clisp.org>
1700 * lib/autoconf/types.m4 (_AC_TYPE_LONG_LONG_SNIPPET): New macro,
1701 extracted from AC_TYPE_LONG_LONG_INT and AC_TYPE_UNSIGNED_LONG_LONG_INT.
1702 (AC_TYPE_LONG_LONG_INT, AC_TYPE_UNSIGNED_LONG_LONG_INT): Use it.
1703 Fixes problem with Sun C 5.[0-8] in 32-bit mode, reported in
1704 <http://lists.gnu.org/archive/html/autoconf-patches/2007-10/msg00210.html>
1705 Suggested by Paul Eggert.
1707 2007-10-28 Jim Meyering <meyering@redhat.com>
1709 * README-hacking: Autoconf, Automake, and Perl are required to build.
1710 List Gzip and Tar separately. Suggested by Ralf Wildenhues.
1712 2007-10-28 Jim Meyering <meyering@redhat.com>
1714 README-hacking: Recommend running autoreconf -vi.
1715 * GNUmakefile (dummy): Use autoreconf -i, with appropriate PATH,
1716 so that we use just-built tools when they're available.
1717 Suggestions from Ralf Wildenhues.
1719 2007-10-28 Jim Meyering <meyering@redhat.com>
1721 Make inter-release --version output more useful.
1723 Now, each unofficial build has a version "number" like 2.61a-19-58dd,
1724 which indicates that it is built using the 19th change set
1725 (in _some_ repository) following the "v2.61a" tag, and that 58dd
1726 is a prefix of the commit SHA1.
1727 * build-aux/git-version-gen: New file.
1728 * configure.ac: Run it to set the version.
1729 (AM_INIT_AUTOMAKE): Don't check NEWS here.
1730 * Makefile.am (dist-hook): Arrange so that .version appears only
1731 in distribution tarballs, never in a checked-out repository.
1732 * .gitignore: Add .version here, too. Just in case.
1733 * tests/Makefile.am ($(srcdir)/package.m4): Depend on Makefile,
1734 not configure.ac, now that the version number changes automatically.
1736 Ensure that $(VERSION) is up to date for dist-related targets.
1737 * GNUmakefile: Arrange to rerun autoconf, if the version reported by
1738 git-version-gen doesn't match $(VERSION), but only for dist targets.
1740 2007-10-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1742 Fix `Deep Package' failure with a configure script early in PATH
1743 * tests/torture.at (Deep Package): Add `.' early in PATH.

1759 efficiently.
1760 * tests/m4sh.at (AS@&t@_HELP_STRING): Test overquoted comma.
1761 * doc/autoconf.texi (Evaluation Macros) <m4_expand>: Update
1762 documentation.
1764 2007-10-23 Paul Eggert <eggert@cs.ucla.edu>

1771 * lib/autoconf/c.m4 (AC_C_RESTRICT): Work around Sun C++ compatibility
1772 problem reported by Bruno Haible in
1773 <http://lists.gnu.org/archive/html/bug-autoconf/2007-10/msg00027.html>.
1775 2007-10-22 Eric Blake <ebb9@byu.net>
1777 * doc/autoconf.texi (Particular Types): Mention bug in HP-UX 11.00
1778 preprocessor.
1780 2007-10-22 Paul Eggert <eggert@cs.ucla.edu>
1782 Don't check for bug in HP-UX 11.00 cpp.
1783 * lib/autoconf/types.m4 (AC_TYPE_UNSIGNED_LONG_LONG_INT):
1784 Use -1ull rather than -1u, since that causes problems with gnulib; see
1785 <http://lists.gnu.org/archive/html/bug-gnulib/2007-10/msg00329.html>.
1787 2007-10-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

1803 escaping of backslash in here-documents.
1805 Fix `Deep Package' test failure on FreeBSD.
1806 * tests/torture.at (Deep Package): Do not add `.' to $PATH
1807 unnecessarily. Do not try running `/bin/sh configure' with a
1808 configure script to be found in $PATH, if the shell does not do
1809 this resolution. Fixes test failure on FreeBSD.
1811 Fix config header generation with AIX awk.
1812 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS_PREPARE): In awk
1813 script, use helper array D_is_set, as `" 0"' does not evaluate

1848 m4_expand.
1850 Improve AT_BANNER handling.
1851 * lib/autotest/general.m4 (BANNERS): New named diversion.
1852 (TESTS_END): Diversion no longer used.
1853 (AT_INIT) <at_func_banner, BANNERS>: Factor all banners into a
1854 shell function, which prints only as needed, using an associative
1855 array of banner text from a special diversion.
1856 <PARSE_ARGS_END>: No longer need awk to find banners.
1857 <TESTS>: Banners are no longer processed by main driver loop, so
1858 we no longer need case statement.
1859 (AT_BANNER): Rewrite to populate new diversion.
1860 (AT_SETUP): Each test invokes its own banner. No output is needed
1861 to the TESTS diversion.
1862 * doc/autoconf.texi (Writing Testsuites): Document slight
1863 semantics change.
1864 * tests/autotest.at (AT_BANNERS): Enhance test.

1888 duplication bug by using new macro.

1890 programs with stdin redirected, so programs that don't
1891 understand --version won't try to behave interactively.

1908 columns.
1909 (TEST_FUNCTIONS): Based on recent changes, rename...
1910 (TEST_GROUPS): ...to this.
1912 Reject FreeBSD m4.

2889 * lib/autoconf/c.m4 (AC_OPENMP): Don't echo --enable-openmp
2890 choice, since that's what we do with --enable-largefile etc.
2891 Redo indenting and assignments to simplify things a bit, and make
2892 the parens work with Emacs.
2894 * doc/autoconf.texi (Generic Compiler Characteristics): Fix typo
2895 in my previous change: AC_C_OPENMP -> AC_OPENMP. Reported by Bruno
2896 Haible.
2898 2007-05-21 Noah Misch <noah@cs.caltech.edu>

2917 * NEWS: Mention AC_C_OPENMP.
2918 * lib/autoconf/c.m4 (AC_C_OPENMP): New macro.
2919 * doc/autoconf.texi (C Compiler): Document AC_C_OPENMP.
2920 Based in part on Steven G. Johnson's investigations for the AX_OPENMP
2921 macro in the Autoconf macro archive.
2923 2007-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

2973 section titles and other comments; no code change.
2975 2007-05-01 Kevin Ryde <user42@zip.com.au>
2977 * doc/autoconf.texi (Particular Programs): Typo
2978 @acindex{AC_PROG_MKDIR_P} shouldn't have "AC" in that call.
2980 2007-04-30 Paul Eggert <eggert@cs.ucla.edu>
2982 * lib/m4sugar/m4sh.m4 (_AS_SHELL_FN_SPY): Don't imply that
2983 'configure' will fail if the shell lacks proper support for shell
2984 functions. Suggested by RMS.
2986 2007-04-29 Paul Eggert <eggert@cs.ucla.edu>
2988 * doc/autoconf.texi (Limitations of Builtins): Correct the warning
2989 about Solaris /bin/printf '%010000x' 123. Problem reported by
2990 Bruno Haible.
2992 2007-04-28 Paul Eggert <eggert@cs.ucla.edu>
2994 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't look
2995 for a.* when searching for executables, as this prevents users
2996 from having files like a.c. Problem reported by Ralf Wildenhues in:
2997 http://lists.gnu.org/archive/html/autoconf-patches/2007-04/msg00029.html
2998 This fixes a problem introduced on 2000-12-19.

3002 * doc/autoconf.texi (Limitations of Builtins): Warn about Solaris
3003 /bin/printf '%010000x' 123. Problem reported by Arto C. Nirkko
3004 via Bruno Haible.

3008 * NEWS: Document recent changes to AC_CHECK_ALIGNOF, AC_CHECK_SIZEOF,
3009 AC_CHECK_TYPE, AC_CHECK_TYPES.
3010 * doc/autoconf.texi (Generic types): C types must be type-names
3011 (the C terminology), not type-ids (the C++ term). C++ types
3012 must not be anonymous.
3013 * lib/autoconf/types.m4 (_AC_CHECK_TYPE_NEW): Remove special case
3014 for C++; this drops support for anonymous struct and union types,
3015 which were problematic anyway.
3016 * tests/semantics.at (AC_CHECK_HEADERS_NEW): Adjust test to work even
3017 for C++.
3019 2007-04-12 Jim Meyering <jim@meyering.net>

3032 on types imposed by AC_CHECK_TYPE, AC_CHECK_TYPES.
3033 (Generic Compiler Characteristics): AC_CHECK_SIZEOF now works
3034 with objects too. Document the restrictions on its use.
3035 Document the restrictions on AC_CHECK_ALIGNOF's type argument.
3036 * lib/autoconf/types.m4 (_AC_CHECK_TYPE_NEW):
3037 For C, just try sizeof (TYPE) and sizeof ((TYPE)); if the former
3038 works but the latter doesn't, then it's a valid type.
3039 This lets people use function types and so forth.
3040 For C++ there doesn't seem to be a simple solution, so leave it alone.
3041 (AC_CHECK_SIZEOF): Allow argument to be a variable.
3042 (AC_CHECK_SIZEOF, AC_CHECK_ALIGNOF): Don't bother to invoke
3043 AC_CHECK_TYPE; that wasn't documented or necessary.
3045 2007-04-11 Stepan Kasal <kasal@ucw.cz>
3047 * lib/autoconf/general.m4 (_AC_LINK_IFELSE): Skip AS_TEST_X

3063 obsolescent. Suggested by Bruno Haible.
3064 * NEWS: Document this.
3066 2007-03-29 Paul Eggert <eggert@cs.ucla.edu>
3068 * doc/autoconf.texi (Here-Documents, Limitations of Builtins):
3069 (Limitations of Usual Tools): Don't say "older" if Solaris 10 by
3070 default still has the problem. Problem reported by Bruce Korb.

3090 * doc/autoconf.texi (C Compiler): Mention that AC_PROG_CC_C99 also
3091 checks for unsigned long long int.
3093 2007-03-19 Paul Eggert <eggert@cs.ucla.edu>
3095 * doc/autoconf.texi (Limitations of Usual Tools): Warn about other
3096 nonstandard grep R.E. escape sequences.
3098 2007-03-17 Jim Meyering <jim@meyering.net>
3100 * doc/autoconf.texi: Adjust grammar around use of "heuristics".
3101 (Limitations of Usual Tools): Also list \< and \>, and mention that
3102 HP-UX's grep, like the one from Solaris, does not support that syntax.
3104 2007-03-09 Stepan Kasal <kasal@ucw.cz>
3106 * doc/autoconf.texi (Specifying Names): `--host' does not
3107 change the build type.
3109 2007-03-05 Paul Eggert <eggert@cs.ucla.edu>
3111 * doc/autoconf.texi (C Compiler): Warn that AC_C_BIGENDIAN
3112 suggests AC_CONFIG_HEADERS.

3119 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Fix typo "__LITLE_ENDIAN__".
3120 Problem reported by Paolo Bonzini in:
3121 http://lists.gnu.org/archive/html/autoconf-patches/2007-02/msg00024.html
3122 * tests/semantics.at (AC_C_BIGENDIAN): Don't reject hosts that have
3123 universal binaries. Problem reported by Elias Pipping.
3125 2007-02-27 Paul Eggert <eggert@cs.ucla.edu>
3127 * NEWS: AC_C_BIGENDIAN now supports universal binaries a la Mac OS X.
3128 * doc/autoconf.texi (C Compiler): Document this. There is a new
3129 extra argument ACTION-IF-UNIVERSAL.
3130 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Implement this.
3131 Add support for Solaris-style _LITTLE_ENDIAN and _BIG_ENDIAN.
3132 Reindent for sanity's sake.
3134 2007-02-24 Eric Blake <ebb9@byu.net>
3136 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Update
3137 copyright.

3142 2007-02-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3144 * lib/autotest/general.m4 (AT_INIT): With --clean, return exit
3145 status of rm so we know when it failed.
3146 If cleaning of test dir failed before running the test, warn.
3147 Output the line separator in verbose mode before the warning
3148 to make clear the warning belongs to the following test.
3150 2007-02-08 Paul Eggert <eggert@cs.ucla.edu>
3152 * doc/autoconf.texi (Parentheses): Mention problem with (( in
3153 shells.

3159 errors introduced in last change.
3161 2007-02-07 Paul Eggert <eggert@cs.ucla.edu>
3163 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Prefer \r to

3165 carriage return.
3166 * doc/autoconf.texi (Limitations of Usual Tools): Document problem
3167 with traditional Awk and begin.
3168 * tests/torture.at (Limitations of Builtins): Document the problem
3169 with Bash 2.03 printf.

3173 2007-02-06 Ralf Menzel <menzel@ls6.cs.uni-dortmund.de> (tiny change)
3175 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Redirect
3176 input from /dev/null in awk test, so even Solaris /usr/bin/awk
3177 will not wait for input with a script containing only a BEGIN
3178 rule.
3180 2007-02-03 Paul Eggert <eggert@cs.ucla.edu>
3182 * doc/autoconf.texi (Introduction, Why GNU M4): Clarify M4 version

3202 2007-01-28 Paul Eggert <eggert@cs.ucla.edu>
3204 * doc/autoconf.texi (Shellology): pdksh 5.2.14 is still the
3205 latest version.
3206 (Shell Substitutions): Note problems with @{var:=value} etc.
3207 Add a new section for problems with @{#var} etc. Problem noted
3208 by Ralf Wildenhues. See:

3211 2007-01-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3213 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Also
3214 AC_SUBST([MKDIR_P]), so that Automake < 1.10 will pick up its
3215 trace, if a package uses AC_PROG_MKDIR_P explicitly. The actual
3216 substitution will still be done by the special code.
3217 Report by Jim Meyering.
3219 * doc/autoconf.texi (File System Conventions): Mention that
3220 $PATH_SEPARATOR is for the build system only.
3221 Report by Keith Marshall.

3231 Test all 8 bit non-NUL characters.
3232 Report against Automake by Patrick Welche.
3234 2007-01-15 Stepan Kasal <kasal@ucw.cz>
3236 * doc/autoconf.texi: Direntry for "autoconf Invocation" renamed.
3238 2007-01-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3240 * lib/autoconf/programs.m4 (AC_PROG_SED): When closing a pipe
3241 early on the reader side, drop stderr of the input to avoid
3242 `broken pipe' error output; this may happen even with shell
3243 builtin `echo' of some bash versions. Reports by Ian Macdonald
3244 <iamacdo@telkomsa.net> and Sam Sexton <Sam.Sexton@reuters.com>.
3246 2007-01-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3248 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Use newlines to

3258 Fix some wording problems noted by Paolo Bonzini in:
3259 http://lists.gnu.org/archive/html/autoconf-patches/2007-01/msg00077.html
3260 * doc/autoconf.texi (Signed Overflow Examples): Give more
3261 discussion about the allow_superuser_privileges example,
3262 and change it a bit to make things clearer.
3263 (Optimization and Wraparound): Clarify whether the compiler
3264 will generate an infinite loop for the example derived from
3265 Autoconf's mktime test.
3266 (Signed Overflow Advice): Say that -ftrapv is meant for debugging.
3267 Also, clarify unsigned multiplication overflow.
3269 2007-01-04 Eric Blake <ebb9@byu.net>
3271 * bin/Makefile.am (RELEASE_YEAR): New macro.
3272 (edit): Use it to supply correct copyright year to scripts.
3273 * bin/autoconf.as (version): Use it.
3274 * bin/autoheader.in ($version): Likewise.
3275 * bin/autom4te.in ($version): Likewise.
3276 * bin/autoreconf.in ($version): Likewise.
3277 * bin/autoscan.in ($version): Likewise.
3278 * bin/autoupdate.in ($version): Likewise.
3279 * bin/ifnames.in ($version): Likewise.
3281 2007-01-02 Paul Eggert <eggert@cs.ucla.edu>
3283 * doc/autoconf.texi (Integer Overflow): Revised based on today's
3284 feedback. The most important changes document what happens when
3285 you convert an out-of-range value to a signed integer type, and
3286 say that (sum < a) != (b < 0) reliably detects overflow when sum =
3287 a + b.
3289 * doc/autoconf.texi (Integer Overflow): Greatly expand and
3290 rewrite, taking notions from the recent discussion on the gcc and
3291 autoconf mailing lists; please see
3292 http://lists.gnu.org/archive/html/autoconf-patches/2006-12/msg00091.html
3293 and follow the many links.
3294 (Integer Overflow Basics, Signed Overflow Examples):
3295 (Optimization and Wraparound, Signed Overflow Advice):
3296 (Signed Integer Division): New sections.
3298 2006-12-28 Steven G. Johnson <stevenj@alum.mit.edu>
3300 * lib/autoconf/general.m4 (AC_DEFINE_TRACE): Don't include
3301 preprocessor macro arguments in traced name.
3302 * doc/autoconf.texi (Defining symbols): Document longstanding
3303 support for AC_DEFINE-ing macros with arguments, and document
3304 behavior when the same variable has multiple AC_DEFINEs.
3305 * lib/autoconf/fortran.m4 (_AC_FC_WRAPPERS): Revert to the
3306 old implementation which AC_DEFINEs the FC_FUNC and FC_FUNC_
3307 macros directly, giving much shorter and simpler code.
3309 2006-12-28 Malcolm Purvis <malcolmp@xemacs.org> (trivial change)
3311 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Insert a
3312 space before "$ac_configure_args" to prevent a 'config.status
3313 --recheck' failure if ac_configure_args doesn't contain a leading
3314 space. This works around a problem with the XEmacs configure.ac,
3315 which uses the (undocumented) ac_configure_args variable
3316 inconsistently with Autoconf.
3318 2006-12-22 Paul Eggert <eggert@cs.ucla.edu>
3320 * lib/autoconf/functions.m4 (AC_FUNC_MKTIME):
3321 Include <limits.h>, and use its INT_MAX to rewrite the
3322 j loop so that it does not overflow 'int'. Problem reported by
3323 Ralf Wildenhues in
3324 <http://lists.gnu.org/archive/html/bug-gnulib/2006-12/msg00084.html>.
3325 Play it safe by shifting left by 1 rather than multiplying by 2,
3326 as GCC is less likely to optimize this away when the value
3327 is signed (when it assumes overflow leads to undefined behavior).
3328 Also, don't assume time_t uses two's complement.
3330 2006-12-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3332 * tests/torture.at (Substitute a 2000-byte string): Avoid using
3333 a 10kB long (multi-line) string literal, OpenServer 5.0.7 ksh
3334 dumps core on it. Report by Tim Rice.
3336 2006-12-18 Steven G. Johnson <stevenj@alum.mit.edu>
3338 * lib/autoconf/general.m4 (AC_ARG_ENABLE): Print help about
3339 --disable-option-checking to --help output even when
3340 AC_PRESERVE_HELP_ORDER is not used.
3341 (_AC_INIT_PARSE_ENABLE2): Print warnings using actual --enable or
3342 --with argument, rather than argument with [-.] replaced by
3343 underscores.
3344 * NEWS: Fix typo in previous change; the news was in the
3345 wrong section.
3347 2006-12-18 Paul Eggert <eggert@cs.ucla.edu>
3349 * NEWS: Warnings are now generated by default for unknown
3350 --enable-* and --with-* options.
3351 * doc/autoconf.texi (Option Checking): Renamed from
3352 (Configure Option Checking). Tighten up the wording a bit.
3353 (External Software, Package Options): Cross-reference to Option
3354 Checking, and use this to shorten our section.
3355 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Prefer test -n
3356 "$x" to test "x$foo" != x.
3357 * lib/autoconf/status.m4 (AC_OUTPUT): Likewise.
3358 Don't warn if $enable_option_checking is "no".
3359 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Initialize
3360 ac_unrecognized_opts to the empty string.
3361 Don't echo the unrecognized opts, as this might mishandle
3362 backslashes or leading -.
3363 (AC_PRESERVE_HELP_ORDER): Put the --disable-option-checking
3364 usage next to the other --disable-FEATURE options in the
3365 help string.
3367 2006-12-18 Steven G. Johnson <stevenj@alum.mit.edu>
3369 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS, _AC_INIT_PARSE_ARGS):
3370 (_AC_INIT_PARSE_ENABLE2, _AC_INIT_HELP, _AC_ENABLE_IF):
3371 Print warning for unrecognized --with and --enable options
3372 (AC_DISABLE_OPTION_CHECKING): New macro to disable warnings.
3373 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS, _AC_OUTPUT_SUBDIRS):
3374 Disable option checking when subdirs are configured.
3375 (AC_OUTPUT): If warnings are enabled, print warning about
3376 unrecognized --with and --enable options at the end of
3377 the configure output (as well as at the beginning).
3378 * doc/autoconf.texi (Option Checking): New node.
3379 Document new option warning functionality.
3381 2006-12-16 Eric Blake <ebb9@byu.net>
3383 * configure.ac (AC_INIT): Bump version, since 2.61a is released.
3384 * NEWS: Start news for current version.
3386 2006-12-15 Paul Eggert <eggert@cs.ucla.edu>
3388 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT):
3389 Define HAVE_GETMNTENT to 1, not to the empty string.
3390 Problem originally reported by Jochen Friedrich in
3391 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=403243>.
3393 This change prompted by a problem report by Andrey Simonenko in
3394 <http://lists.gnu.org/archive/html/bug-autoconf/2006-12/msg00026.html>.
3395 * doc/autoconf.texi (Defining Symbols): AC_DEFINE works for
3396 object-like macros only, in the traditional portable character
3397 set.
3398 * lib/autoconf/general.m4 (AC_DEFINE_TRACE_LITERAL):
3399 Warn about attempts to define things that are not identifiers.
3400 * lib/autoconf/fortran.m4 (_AC_FC_WRAPPERS): Rewrite to avoid
3401 awful hack that AC_DEFINEd macro names containing parentheses.
3403 2006-12-12 Paul Eggert <eggert@cs.ucla.edu>
3405 * doc/autoconf.texi: Undo some of the 2006-12-10 change. It was
3406 too drastic, even if Texinfo in theory requires it for info mode.
3408 (config.status Invocation): Renamed back from Recreating a
3409 Configuration).
3410 (Obsolete config.status Use): Renamed back from Obsolete Recreation.
3411 (Autoconf 2.13): Renamed back from 20th-century Autoconf 2.
3413 2006-12-11 Paul Eggert <eggert@cs.ucla.edu>
3415 * NEWS: Version 2.61a.
3417 2006-12-11 Paul Eggert <eggert@cs.ucla.edu>
3418 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3420 * NEWS: Document changes with echo and printf, and the lack
3421 of limits on the total size of multi-line values of substituted
3422 variables, and the AC_FUNC_FSEEKO fix.
3424 2006-12-10 Paul Eggert <eggert@cs.ucla.edu>
3426 * doc/autoconf.texi (Writing Autoconf Input): Renamed from
3427 Writing configure.ac.
3428 (Autoconf Input Layout): Renamed from configure.ac Layout.
3429 (Recreating a Configuration): Renamed from config.status Invocation.
3430 (Obsolete Recreation): Renamed from Obsolete config.status Use.
3431 (acconfig Header): Renamed from acconfig.h.
3432 (20th-century Autoconf 2): Renamed from Autoconf 2.13.
3433 (Writing Testsuites): Renamed from Writing testsuite.at.
3434 (Autom4te Cache): Renamed from autom4te.cache.
3436 * BUGS: Remove mention of VPATH problem, since it's now documented
3437 not to be a bug in the Autoconf build procedure itself, but rather
3438 a problem with the proprietary `make' programs.
3440 * doc/autoconf.texi (Build Directories): Add a cross reference
3441 to VPATH and Make.
3443 * build-aux/config.guess, build-aux/config.sub, build-aux/texinfo.tex:
3444 * doc/standards.texi: Sync from gnulib.
3446 * man/autoconf.1, man/autoheader.1, man/autom4te.1, man/autoreconf.1:
3447 * man/autoscan.1, man/autoupdate.1, man/config.guess.1:
3448 * man/config.sub.1, man/ifnames.1: Remove from CVS, since they're
3449 generated automatically.
3451 2006-12-06 Paul Eggert <eggert@cs.ucla.edu>
3453 * lib/autoconf/c.m4 (_AC_PROG_CC_C89): Also try -xc99=all, for Sun
3454 C 5.8 on Solaris 10. Using -xc99=all rather than -xc99 bypasses
3455 the buggy -xc99 option of Forte Developer 7 C on Solaris 9.
3457 2006-12-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3459 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Drop the
3460 `CEOF$ac_eof' special marker, the awk script cannot contain a
3461 line matching `^CEOF', so this is not needed any more.
3462 * tests/torture.at (Substitute a newline): Expose the `%!_!# '
3463 special marker in the test.
3465 2006-12-06 Stepan Kasal <kasal@ucw.cz>
3467 * tests/tools.at (autom4te preselections): Use `find -newer';
3468 remove one of the sleeps.
3470 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE): Make it
3471 more readable, using ...
3472 (_AC_INIT_PARSE_ENABLE2): ... this new helper macro.
3474 * doc/autoconf.texi (autoheader Invocation): Do not double-
3475 quote the parameter of `AH_BOTTOM' in the example.
3477 2006-12-05 Stepan Kasal <kasal@ucw.cz>
3479 * doc/autoconf.texi (Configuration Headers): Remove the
3480 example with multiple input files.
3481 (autoheader Invocation): Encourage `AH_BOTTOM', discouraging
3482 multiple input files.
3484 2006-12-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3486 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): When
3487 creating the awk substitution script, handle one input line at a
3488 time, so that the maximum length of a substituted (multi-line)
3489 value is not limited by the size of the sed pattern space.
3490 The trade-off is a slightly repetitive sed script.
3491 * doc/autoconf.texi (Limitations of Usual Tools): Branch labels
3492 can only have up to 7 characters, due to Solaris 10 /bin/sed.
3493 * tests/torture.at (Substitute a 2000-byte string): Increase the
3494 test with several long lines, they should not be caught by sed
3495 limits any more.
3497 * tests/tools.at (autom4te preselections): New test, to flag
3498 entries missing from autom4te.cfg.
3499 Report by David Byron <dbyron@hheld.com>.
3501 * tests/torture.at (Substitute a 2000-byte string): Actually use
3502 AC_PROG_AWK, so the last change works as intended.
3503 (Substitute and define special characters): Likewise.
3504 (Substitute a newline): Likewise.
3506 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Use `$AWK'
3507 instead of `awk' consistently.
3508 (_AC_OUTPUT_CONFIG_STATUS): Initialize $AWK.
3509 * tests/torture.at (Torturing config.status): Test both the
3510 result of AC_PROG_AWK and plain awk.
3511 (Substitute a 2000-byte string): Likewise.
3512 (Substitute and define special characters): Likewise.
3513 (Substitute a newline): Likewise.
3515 2006-12-04 Paul Eggert <eggert@cs.ucla.edu>
3517 * lib/autoconf/functions.m4 (AC_FUNC_FSEEKO): Check that fseeko
3518 can be assigned to a function pointer. Problem reported by
3519 Peter Palfrader in <http://bugs.debian.org/401377>. Based on
3520 part of a patch by Ralf Wildenhues in that same bug report.
3522 2006-12-01 Paul Eggert <eggert@cs.ucla.edu>
3524 * tests/mktests.sh (ac_exclude_list): Exclude AC_FUNC_SETVBUF_REVERSED.
3525 * tests/semantics.at (AC_FUNC_SETVBUF_REVERSED): New test.
3527 2006-12-01 Eric Blake <ebb9@byu.net>
3529 * lib/autoconf/c.m4 (AC_LANG_INT_SAVE): Avoid newline, to aid in
3530 cross-compiling from cygwin to mingw.
3531 Reported by Bob Rossi. This resurrects the 2000-11-30 patch to
3532 aclang.m4, which was mistakenly removed in the 2001-09-17 patch
3533 to lib/autoconf/c.m4.
3535 2006-12-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3537 * lib/m4sugar/m4sh.m4 (_AS_ECHO_PREPARE): Use a longer test
3538 string for more reliable failure. Wrap the entire test that
3539 causes the broken Solaris printf to dump core, in a subshell,
3540 so the segmentation fault message is reliably suppressed.
3541 Fix shell expansion errors by using /usr/ucb/echo always;
3542 avoid an error on systems without it by another subshell.
3543 Avoid m4 expansion of `$1'. Set the zeroth argument of the
3544 subshell-$as_echo to `as_echo', for better error message.
3546 2006-11-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3548 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): If `BASH_ARGV' or
3549 `BASH_SOURCE' contain a newline, set them to empty, as they may
3550 not be unset.
3552 2006-11-27 Paul Eggert <eggert@cs.ucla.edu>
3554 Turn AC_FUNC_SETVBUF_REVERSED into a noop. It's been obsolete for
3555 years and is too hard to maintain now. The last straw was
3556 reported by Jerker Baeck in
3557 <http://lists.gnu.org/archive/html/autoconf/2006-11/msg00102.html>.
3558 * NEWS: AC_FUNC_SETVBUF_REVERSED is now obsolete.
3559 * doc/autoconf.texi (Particular Functions): Move
3560 AC_FUNC_SETVBUF_REVERSED from here...
3561 (Obsolete Macros): ... to here. Say that it does nothing now.
3562 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
3563 Turn into (almost) a no-op.
3565 * lib/autoconf/c.m4 (AC_PROG_GCC_TRADITIONAL, AC_C_CONST):
3566 (AC_C_VOLATILE):
3567 Do not recommend via AN_FUNCTION, AN_IDENTIFIER, or AN_HEADER.
3568 These macros are obsolescent and new applications shouldn't need them.
3569 * lib/autoconf/functions.m4 (AC_FUNC_CLOSEDIR_VOID, AC_REPLACE_FNMATCH):
3570 (AC_FUNC_GETLOADAVG, AC_FUNC_GETPGRP, AC_FUNC_MEMCMP):
3571 (AC_FUNC_SELECT_ARGTYPES, AC_FUNC_SETPGRP, AC_FUNC_STAT, AC_FUNC_LSTAT):
3572 (AC_FUNC_STRFTIME, AC_FUNC_SETVBUF_REVERSED, AC_FUNC_UTIME_NULL):
3573 (AC_FUNC_VPRINTF): Likewise.
3574 * lib/autoconf/headers.m4 (AC_HEADER_DIRENT, AC_HEADER_STAT):
3575 (AC_HEADER_STDC, AC_HEADER_SYS_WAIT, AC_HEADER_TIME): Likewise.
3576 * lib/autoconf/types.m4 (AC_STRUCT_TM): Likewise.
3578 * doc/autoconf.texi (Setting Output Variables): Mention that
3579 @VAR1@VAR2 has unspecified behavior. Problem reported by
3580 Ralf Wildenhues.
3581 * NEWS: Mention this.
3583 * Makefile.am: Put only a single '#' into the copyright notice,
3584 so that it's also present in the output file. Standardize wording
3585 in makefile copyright notices to match GNU coding standards.
3586 * bin/Makefile.am: Likewise.
3587 * doc/Makefile.am: Likewise.
3588 * lib/Makefile.am: Likewise.
3589 * lib/freeze.mk: Likewise.
3590 * lib/autoconf/Makefile.am: Likewise.
3591 * lib/autoscan/Makefile.am: Likewise.
3592 * lib/autotest/Makefile.am: Likewise.
3593 * lib/m4sugar/Makefile.am: Likewise.
3594 * man/Makefile.am: Likewise.
3595 * tests/Makefile.am: Likewise.
3596 * lib/emacs/Makefile.am: Remove copyright notice; it's just a
3597 one-line file.
3599 2006-11-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3601 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Fix error
3602 in the sed script that mangles the awk script: delete up to the
3603 first exclamation mark only.
3604 * tests/torture.at (Substitute and define special characters):
3605 Test '!' too.
3607 2006-11-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3609 Rewrite config files generation: avoid quadratic growth in
3610 the number of substituted variables by using awk instead of sed
3611 for the bulk of the substitutions.
3612 * NEWS: Mention this.
3613 * doc/autoconf.texi (Setting Output Variables): `|#_!!_#|' is also
3614 forbidden in the output (and thus input) file.
3615 * lib/autoconf/status.m4 (_AC_AWK_LITERAL_LIMIT): New macro.
3616 (_AC_OUTPUT_FILES_PREPARE): Instead of several sed scripts,
3617 generate just one large awk script for substitutions,
3618 eliminating much of the earlier complexity, while adding some
3619 new complexity. Only expand the substitution templates at
3620 configure time, for smaller configure script size. If
3621 _AC_SUBST_FILES are used, test 'awk' for working getline support
3622 at config.status time. If absent, interpolate through the
3623 shell. The awk script was written with much help
3624 from Paolo Bonzini and Paul Eggert.
3625 (_AC_SED_CMD_NUM, _AC_SED_DELIM_NUM, _AC_SED_FRAG): Removed.
3626 (_AC_SED_FRAG_NUM): Likewise.
3627 (_AC_SUBST_CMDS): Renamed from...
3628 (_AC_SED_CMDS): ...this.
3629 (_AC_OUTPUT_FILE): Use _AC_SUBST_CMDS.
3630 * tests/torture.at (Substitute a 2000-byte string): Also
3631 substitute a line with 1000 words, and a variable with several
3632 long lines.
3633 (Substitute and define special characters): Test awk special
3634 characters, and put substitution input strings `@foo@' in the
3635 output, to test that no recursion happens; test several other
3636 combinations from Paolo Bonzini.
3638 2006-11-25 Paul Eggert <eggert@cs.ucla.edu>
3640 * lib/autotest/general.m4 (AT_INIT): Undo recent changes
3641 that replaced echo with AS_ECHO where this wasn't necessary.
3642 Problem reportd by Ralf Wildenhues.
3643 * lib/m4sugar/m4sh.m4 (_AS_ECHO_PREPARE): Port to Solaris 7,
3644 where "/usr/bin/printf '%s\n' S" dumps core if S is long.
3645 This is Sun bug 4206210. Problem reportd by Ralf Wildenhues.
3647 2006-11-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3649 * lib/freeze.mk (GREP): Removed, no need to initialize this.
3651 2006-11-21 Paul Eggert <eggert@cs.ucla.edu>
3653 * doc/autoconf.texi (Limitations of Usual Tools): Don't claim
3654 that traditional Awk lacks 3-arg "split". It has it.
3655 Mention that FS must be a single character, and a few other
3656 99-byte limits of traditional Awk.
3657 Mention that if (i in a) doesn't work with traditional Awk.
3659 2006-11-18 Paul Eggert <eggert@cs.ucla.edu>
3661 * tests/autotest.at (BSx641-newline in command):
3662 (BS-BS-newline in command, BSx640-newline in command):
3663 (Newline-CODE-BS-newline in command):
3664 (Single-quote-BS-newline in command):
3665 (Single-quote-newline-BS-newline in command):
3666 Use printf '%s\n' instead of echo, for portability to hosts
3667 where echo interprets backslashes. This will break on hosts
3668 that lack printf, but for now let's assume all such hosts
3669 are dead (if not, we should get reports of test failures).
3671 2006-11-17 Paul Eggert <eggert@cs.ucla.edu>
3673 'echo' has some portability problems, when given a first argument
3674 with a leading '-', or when given any argument containing '\'.
3675 Avoid using 'echo' in these cases.
3676 * bin/Makefile.am $(bin_SCRIPTS): Rewrite to avoid 'echo' entirely.
3677 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX, AC_PROG_OBJC): Likewise.
3678 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
3679 * lib/autotest/general.m4 (AT_INIT): Likewise.
3680 * bin/autoconf.as: Use AS_ECHO rather than plain echo, when the
3681 argument might be unportable.
3682 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Likewise.
3683 * lib/autoconf/erlang.m4 (AC_LANG(Erlang)): Likewise.
3684 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT):
3685 (_AC_FC_LIBRARY_LDFLAGS): Likewise.
3686 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Likewise.
3687 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE, _AC_INIT_PREPARE):
3688 (_AC_ARG_VAR_VALIDATE, AC_ARG_PROGRAM, _AC_MSG_LOG_CONFTEST):
3689 (AC_RUN_LOG, _AC_RUN_IFELSE, _AC_LIBOBJS_NORMALIZE): Likewise.
3690 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Likewise.

3696 * lib/autotest/general.m4 (_AT_CREATE_DEBUGGING_SCRIPT, AT_INIT):
3697 (AT_CLEANUP, _AT_DECIDE_TRACEABLE, _AT_CHECK): Likewise.

3699 (_AS_BASENAME_SED, _AS_DIRNAME_SED, AS_MKDIR_P, AS_TMPDIR, AS_UNAME):
3700 (AS_TR_SH, AS_TR_CPP, AS_VAR_GET): Likewise.
3701 * bin/autoconf.as: Redo verbose flag implementation, as the old
3702 scheme wouldn't work with AS_ECHO.
3703 * lib/autotest/general.m4 (AT_INIT): Likewise.
3704 * lib/autoconf/general.m4 (AC_MSG_RESULT, AC_MSG_RESULT_UNQUOTED):
3705 Don't use ECHO_T, since ECHO_N is now reliable.
3706 * lib/autotest/general.m4 (AT_INIT): Likewise.
3707 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Use sed "$script"
3708 rather than using a here-document to put the script into a file.
3709 (_AC_DO_ECHO): Hoist the eval out of the echo, so that we can
3710 use AS_ECHO.
3711 * lib/m4sugar/m4sh.m4 (AS_VAR_GET): Likewise.
3712 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Use
3713 AS_ECHO_N rather than ECHO_N and ECHO_C. This doesn't fix any
3714 bug, but we might as well stop using ECHO_N and ECHO_C internally.
3715 * lib/autotest/general.m4 (AT_SETUP): Likewise.
3716 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N): Likewise.
3717 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
3718 (_AC_OUTPUT_MAIN_LOOP): Rework echo so that it has just one
3719 operand, as AS_ECHO requires. Avoid double file name expansion.
3720 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Invoke _AS_ECHO_PREPARE.
3721 Don't set as_nl, since _AS_ECHO_PREPARE does that now.
3722 (_AS_PREPARE): Comment that _AS_ECHO_N_PREPARE is just for user code.
3723 (AS_ECHO, AS_ECHO_N, _AS_ECHO_PREPARE): New macros.
3724 * tests/c.at (AC_PROG_CPP without warnings, AC_PROG_CPP via CC):
3725 Double-quote strings that would otherwise contain M4 comments.
3726 * tests/m4sh.at (AS_ECHO and AS_ECHO_N): New test.
3728 * configure.ac (AC_INIT): Bump to 2.61a.
3729 * NEWS: Likewise.
3731 2006-11-17 Paul Eggert <eggert@cs.ucla.edu>
3733 Version 2.61.
3735 * configure.ac (AC_INIT): Bump to 2.61.
3736 * NEWS: Likewise.
3738 * tests/autotest.at (Macro with backslash in a test title):
3739 Comment out for now, as this tests neither fails nor passes
3740 reliably. Problem reported by Ralf Wildenhues.
3742 2006-11-16 Paul Eggert <eggert@cs.ucla.edu>
3744 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE): Fix some typos
3745 in previous change, which caused test failures.
3747 2006-11-16 Stepan Kasal <kasal@ucw.cz>
3749 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Factor out
3750 code for --enable, --disable, --with, and --without to...
3751 (_AC_INIT_PARSE_ENABLE): ... a new macro.
3752 * doc/autoconf.texi (Package Options):
3753 * NEWS: Document that AC_ARG_ENABLE allows dots, too.
3755 2006-11-16 Paul Eggert <eggert@cs.ucla.edu>

3813 * doc/autoconf.texi (External Software): Document that AC_ARG_WITH's
3814 first argument may also contain dots.
3816 2006-11-09 Paul Eggert <eggert@cs.ucla.edu>
3818 * tests/mktests.sh (ac_exclude_list): Exclude AC_PROG_CXX_C_O, for

3820 non-working g++ installation.
3822 2006-11-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3823 and Joel E. Denny <jdenny@ces.clemson.edu>
3824 and Paul Eggert <eggert@cs.ucla.edu>

3832 * lib/autoconf/types.m4 (AC_TYPE_LONG_LONG_INT): Set

3834 Imported from a similar patch to gnulib by Bruno Haible.
3836 2006-11-08 Paul Eggert <eggert@cs.ucla.edu>
3838 * NEWS: New macros AC_C_FLEXIBLE_ARRAY_MEMBER, AC_C_VARARRAYS.
3839 * doc/autoconf.texi (C Compiler): Document them.
3840 * lib/autoconf/c.m4 (AC_C_FLEXIBLE_ARRAY_MEMBER, AC_C_VARARRAYS):

3863 ./micro-suite -l and the title in micro-suite.log.
3864 (Backquote in a test title,
3865 Single-quote in a test title,
3866 Double-quote in a test title): Don't expect failure anymore.
3867 (Backslash in a test title): Put a non-whitespace character after the
3868 backslash so that Bourne shells might actually see it as an escape
3869 sequence.
3870 (Brackets in a test title,
3871 Pound in a test title,
3872 Comma in a test title,
3873 Quoted Macro in a test title,

3880 AT_SETUP call so that no M4 code is commented inadvertently somewhere.
3881 The visible effect was a stray [] in the testsuite output.
3883 2006-10-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3885 * doc/autoconf.texi (Limitations of Builtins): Do not invoke
3886 `trap ... 0' inside a function, for AIX sh.
3888 2006-10-26 Paul Eggert <eggert@cs.ucla.edu>
3890 * tests/base.at (AC_COMPUTE_INT): Test **0** rather than 1 / 0,
3891 since powerpc-apple-darwin8-gcc-4.0.1 (Apple Computer, Inc. build
3892 5363) simply issues a warning when dividing by zero at compile
3893 time. Problem reported by Elias Pipping.
3895 2006-10-26 Eric Blake <ebb9@byu.net>
3897 * THANKS: Update.
3898 * doc/autoconf.texi (Evaluation Macros): Improve the example to
3899 show effect on macros that expand with commas.
3900 Reported by Joel E. Denny.
3902 * tests/m4sugar.at (m4_warn, m4_require: circular dependencies):
3903 Also work with M4 1.4.8.

3924 2006-10-24 Paul Eggert <eggert@cs.ucla.edu>
3926 * lib/autoconf/specific.m4 (_AC_SYS_LARGEFILE_MACRO_VALUE):
3927 If FUNCTION-BODY is nonempty, use AC_LINK_IFELSE rather than
3928 AC_COMPILE_IFELSE, to work around problem with OSF/1 4.0F fseeko
3929 reported by Nelson H. F. Beebe for Coreutils 6.4.
3931 * tests/tools.at (autoconf --trace: user macros): Remove test
3932 for tracing multiline macros, since m4 1.4.7a uses a different
3933 way to number lines. Problem reported by Ralf Wildenhues.
3935 2006-10-24 Stepan Kasal <kasal@ucw.cz>
3937 * bin/autom4te.in (handle_m4): Do not redirect stdin to
3938 /dev/null since the heuristics for interactive behaviour was
3939 fixed in CVS m4.
3941 * bin/autom4te.in: With --force, always refresh the output
3942 file. Problem reported by Greg Schafer <gschafer@zip.com.au>.
3944 * bin/autoconf.as: Fix the verbose message at the end.
3946 2006-10-23 Paul Eggert <eggert@cs.ucla.edu>

3963 * lib/autoconf/types.m4: All uses of AC_CACHE_CHECK_INT changed.
3964 * tests/base.at (AC_COMPUTE_INT): Test this, not AC_CACHE_CHECK_INT.
3966 2006-10-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3968 * doc/autoconf.texi (Limitations of Usual Tools): Fix two typos.
3970 2006-10-19 Eric Blake <ebb9@byu.net>

3975 m4_mkstemp.
3976 * doc/autoconf.texi (Redefined M4 Macros): Document m4_mkstemp.

3992 2006-10-14 Stepan Kasal <kasal@ucw.cz>
3994 * lib/m4sugar/m4sh.m4 (AS_LITERAL_IF): Expand $1 before
3995 looking for special shell characters.
3996 * lib/autoconf/functions.m4 (AC_CHECK_FUNC): Do not expand the
3997 macro defined by AS_VAR_PUSHDEF before passing it as a
3998 parameter.
3999 * lib/autoconf/general.m4 (AC_CHECK_FILE, AC_CHECK_DECL):
4000 * lib/autoconf/libs.m4 (AC_SEARCH_LIBS, AC_CHECK_LIB):

4009 2006-10-14 Paul Eggert <eggert@cs.ucla.edu>
4011 (Imported from Automake.)
4012 * build-aux/install-sh (posix_mkdir): Reject FreeBSD 6.1 mkdir -p -m,
4013 which incorrectly sets the mode of an existing destination
4014 directory. In some cases the unpatched install-sh could do the
4015 equivalent of "chmod 777 /" or "chmod 0 /" on a buggy FreeBSD
4016 system. We hope this is rare in practice, but it's clearly worth
4017 fixing. Problem reported by Alex Unleashed in
4018 <http://lists.gnu.org/archive/html/bug-autoconf/2006-10/msg00012.html>.
4019 Also, don't bother to check for -m bugs unless we're using -m;
4020 suggested by Stepan Kasal.
4022 2006-10-14 Paul Eggert <eggert@cs.ucla.edu>
4024 Import this change from Automake:
4026 2006-08-23 Alexandre Duret-Lutz <adl@gnu.org>
4027 * lib/Autom4te/ChannelDefs.pm (usage): Mention that -Wportability
4028 is enabled by default with gnu and gnits strictness.
4029 Report from Bruno Haible.
4031 2006-03-10 Alexandre Duret-Lutz <adl@gnu.org>
4032 * lib/Autom4te/ChannelDefs.pm: Make -Wportability the default in
4033 gnu and gnits modes.
4035 Import this change from Config:
4037 2006-09-20 Ben Elliston <bje@gnu.org>
4038 * build-aux/config.sub (score, score-*): New.
4040 Import this change from Gnulib:
4042 2006-09-16 Karl Berry <karl@gnu.org>
4043 * doc/fdl.texi (ADDENDUM): switch to @heading from @appendixsubsec,
4044 to avoid sectioning errors.
4046 Import these changes from Texinfo:
4048 2006-10-04 Karl Berry <karl@gnu.org>
4049 * build-aux/texinfo.tex (\singlequotechar): rename to \codequoteright.
4050 (\quoteexpand): rename to \rquoteexpand.
4051 (\codequoteleft): new def, to look for @set codequotebacktick.
4052 (\lquoteexpand, \quoteexpand): new defs.
4053 (\lquoteChar, \rquoteChar, \dashChar, \underChar: new \chardef's.
4054 (\code): must use new \...Char values, since now ` is active.
4056 2006-08-26 Karl Berry <karl@gnu.org>
4057 * build-aux/texinfo.tex (\textdegree): New command.
4059 2006-08-12 Karl Berry <karl@gnu.org>
4060 * build-aux/texinfo.tex (error \box0): smaller font.
4062 2006-10-14 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4064 * doc/autoconf.texi (Autoheader Macros): Fix syntax error.
4066 2006-10-13 Stepan Kasal <kasal@ucw.cz>
4068 * doc/autoconf.texi (Autoheader Macros): Warn that the text
4069 added to the template can get mangled.
4071 2006-10-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4073 * lib/autoconf/functions.m4 (AC_FUNC_OBSTACK): In the test,
4074 include the default headers, and redefine obstack_chunk_alloc
4075 and obstack_chunk_free. Fixes false failure with glibc.
4077 2006-10-12 Paul Eggert <eggert@cs.ucla.edu>
4079 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Set as_executable_p,
4080 for backward compatibility with Libtool 1.5.22. Problem reported
4081 by Ralf Wildenhues.
4083 2006-10-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4085 * lib/autoconf/c.m4 (AC_PROG_GCC_TRADITIONAL): Require
4086 AC_PROG_CC.
4087 Report by IOhannes m zmoelnig <zmoelnig@iem.at>.
4089 2006-10-11 Paul Eggert <eggert@cs.ucla.edu>
4091 * NEWS: AC_USE_SYSTEM_EXTENSIONS now defines _TANDEM_SOURCE for
4092 the NonStop platform.
4093 * doc/autoconf.texi (Posix Variants): Likewise.
4094 * lib/autoconf/specific.m4 (AC_USE_SYSTEM_EXTENSIONS): Likewise.
4096 * lib/m4sugar/m4sh.m4 (AS_TEST_X): New macro.
4097 (AS_EXECUTABLE_P): Use as_test_x rather than as_executable_p.
4098 (_AS_TEST_PREPARE): Set as_test_x rather than as_executable_p.
4099 Use a better substitute, by inspecting the output of "ls"
4100 rather than just using ":".
4101 * lib/autoconf/general.m4 (_AC_LINK_IFELSE): Use AS_TEST_X
4102 rather than AS_EXECUTABLE_P, since we needn't worry about
4103 non-regular files here.
4105 * NEWS: Autoconf-generated shell scripts no longer export BIN_SH,
4106 due to configuration hassles with this. See Tonya Underwood's report
4107 <http://lists.gnu.org/archive/html/bug-autoconf/2006-10/msg00003.html>.
4108 * doc/autoconf.texi (Special Shell Variables): Likewise.
4110 2006-10-11 Paul Eggert <eggert@cs.ucla.edu>
4111 Stepan Kasal <kasal@ucw.cz>
4113 * lib/m4sugar/m4sh.m4 (AS_BOURNE_COMPATIBLE): Don't set BIN_SH.
4114 (_AS_DETECT_BETTER_SHELL): Don't look in /usr/bin/posix.
4116 2006-10-11 Stepan Kasal <kasal@ucw.cz>
4118 * lib/m4sugar/m4sh.m4 (AS_BOURNE_COMPATIBLE): Move the
4119 initialization which is not inherited through the environment
4120 (_AS_BOURNE_COMPATIBLE): ... to this new macro.
4121 (_AS_RUN): Call _AS_BOURNE_COMPATIBLE, not AS_BOURNE_COMPATIBLE.
4123 2006-10-09 Paul Eggert <eggert@cs.ucla.edu>
4125 * doc/autoconf.texi (Limitations of Usual Tools): Describe
4126 problems with mkdir -p -m.
4128 2006-10-06 Paul Eggert <eggert@cs.ucla.edu>
4130 * lib/autoconf/c.m4 (_AC_PROG_PREPROC_WORKS_IFELSE): Remove
4131 comment about ac_cpp_err; it was incorrect, and anyway
4132 ac_cpp_err is being removed below.
4133 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE): Don't
4134 set ac_cpp_err to 'yesyes' if preproc_warn_flag and werror_flag
4135 are both 'yes'. In fact, don't bother setting ac_cpp_err at all;
4136 nobody uses it.
4137 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't log our funky tests
4138 with werror_flag and conftest.err and so forth. This is more
4139 compatible with how _AC_PROG_PREPROC_WORKS_IFELSE behaves,
4140 and anyway the user shouldn't normally want to see this gorp logged.
4141 Problem reported by Ralf Wildenhues.
4142 * lib/autoconf/lang.m4 (AC_LANG_WERROR): werror_flag's default is
4143 empty, not 'no', since the rest of the code uses 'test -z'.
4145 2006-10-04 Paul Eggert <eggert@cs.ucla.edu>
4147 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE):
4148 Use a single call to AC_DO_TOKENS rather than multiple, for
4149 efficiency.
4150 (_AC_LINK_IFELSE): Test that resulting file is executable.
4151 Problem reported by mwoehlke in
4152 <http://lists.gnu.org/archive/html/bug-coreutils/2006-10/msg00048.html>.
4154 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Use "test -x /" rather
4155 than creating a file to use with test -x; this is much faster.
4157 2006-10-02 Bruno Haible <bruno@clisp.org>
4159 * lib/autom4te.in (Automake-preselections): Add
4160 AM_GNU_GETTEXT_INTL_SUBDIR, for automake 1.10.
4162 2006-09-27 Stepan Kasal <kasal@ucw.cz>
4164 * doc/autoconf.texi (Writing testsuite.at): Fix a typo: for
4165 standard error, `experr' should be used, not `expout'.
4167 2006-09-26 Paul Eggert <eggert@cs.ucla.edu>
4169 * lib/autoconf/functions.m4 (AC_FUNC_FSEEKO): Don't compile the
4170 fseeko testing program twice; just use the earlier result.
4171 * lib/autoconf/specific.m4 (_AC_SYS_LARGEFILE_MACRO_VALUE):
4172 Set cache var to 'unknown' (not 'no') if leaving the macro unset
4173 still doesn't let the program compile.
4174 (AC_SYS_LARGEFILE): Test for _LARGE_FILES only if earlier tests
4175 failed.
4177 * lib/autoconf/functions.m4: Fix problems reported by Ralf Wildenhues.
4178 (AC_FUNC_ERROR_AT_LINE): Don't bother to check for error.h. Just
4179 include it, without including anything else.
4180 (AC_FUNC_FSEEKO): Avoid gcc -Wall warnings about constant
4181 expressions.
4182 (AC_FUNC_STRNLEN): Require AC_USE_SYSTEM_EXTENSIONS.
4184 2006-09-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4186 * lib/autoconf/functions.m4 (AC_FUNC_ERROR_AT_LINE): Check for
4187 `error.h', and include it, for a `error_at_line' prototype.
4188 Use a nonempty format string in the link test.
4189 * lib/autoconf/functions.m4 (AC_FUNC_WAIT3): Include <sys/wait.h>,
4190 for a declaration of wait3.
4192 2006-09-26 Paul Eggert <eggert@cs.ucla.edu>
4194 * NEWS: AC_CHECK_DECL now also works with aggregate objects.
4195 * doc/autoconf.texi (Generic Declarations): Clarify that AC_CHECK_DECL
4196 can apply to constants too, and that it checks for macro defns.
4197 * lib/autoconf/general.m4 (AC_CHECK_DECL): Assume C89 or better,
4198 and simply cast the identifier to void. This handles structure
4199 values. Problem reported by Ralf Wildenhues.
4200 * tests/semantics.at (AC_CHECK_DECLS): Also check enums.
4202 2006-09-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

4205 structure, and function symbols.
4207 2006-09-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4209 * tests/semantics.at (AC_CHECK_MEMBERS): Also test with a struct
4210 member.

4224 present.

4294 7.1.4 /usr/bin/posix/sh described by Tim Rice in
4295 <http://lists.gnu.org/archive/html/bug-autoconf/2006-09/msg00017.html>.
4297 2006-09-11 Stepan Kasal <kasal@ucw.cz>
4299 * tests/local.at (AT_CHECK_M4): Fix this so that the testsuite
4300 works with GNU M4 1.4.3 again; make the normalized form
4301 match the current m4 message; fix the description.

4307 to catch glibc bug 2821
4308 <http://sourceware.org/bugzilla/show_bug.cgi?id=2821>.
4310 Merge from gnulib as follows: Use AC_CHECK_HEADERS_ONCE instead of
4311 AC_CHECK_HEADERS, and likewise for AC_CHECK_FUNCS_ONCE and
4312 AC_CHECK_FUNCS. Don't check for stdlib.h, since we now
4313 assume C89.

4331 by Dries Kimpe.
4333 2006-09-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4335 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Prefer xlf90/xlf95 over
4336 f90/f95 because the latter drivers of AIX Fortran 9.1 do not
4337 accept files with extension `.f'. For consistency, also prefer
4338 xlf over f77.
4339 * doc/autoconf.texi (Fortran Compiler): Remove mention of bug
4340 from last patch.

4411 deal with LEXLIB.
4412 (_AC_PROG_LEX_YYTEXT_DECL): Handle caching correctly; the old code
4413 didn't work if some values were cached but not others. Test for
4414 broken lex libraries like native ia64-hp-hpux11.22; see
4415 <http://sources.redhat.com/ml/binutils/2003-12/msg00337.html>, and
4416 work around the problem by preferring an empty LEXLIB to -lfl or
4417 -ll. Let the user set LEXLIB='' to indicate no library needed.
4419 * NEWS: Recommend M4 1.4.6 instead of 1.4.5.
4420 * README: Likewise.
4421 * doc/autoconf.texi (Introduction, Why GNU M4): Likewise.

4649 reported by Keith Marshall. Also, don't bother with builddir2,
4650 since it shouldn't be needed any more.
4652 2006-07-07 Paolo Bonzini <bonzini@gnu.org>

4676 Bruno Haible reports in
4677 <http://lists.gnu.org/archive/html/bug-gnulib/2006-06/msg00286.html>
4678 that long long int is 32 bits wide with some nonstandard compilers.

4681 2006-06-30 Paul Eggert <eggert@cs.ucla.edu>
4683 * tests/torture.at (Configuring subdirectories): Set CONFIG_SITE
4684 to a nonexistent file, so that we don't have to worry about
4685 a local site configuration that doesn't use /usr/local.

4691 * doc/autoconf.texi: Be more consistent about using @acronym with
4692 "HP" and "HP-UX". Remove mention of OSF; the old version wasn't
4693 quite right (it talked about "OSF/Tru64", even though the
4694 operating systems were called OSF/1, Digital UNIX, and Tru64 UNIX,
4695 and it even mentioned "OSF 4"!) and at this point there's little
4696 reason to talk about OSF any more, since it died in 1994.
4697 (Specific Compiler Characteristics): Simplify example of
4698 negative-size array.
4699 (File Descriptors): Reorder to make the text flow better.
4700 Remove joke about "appreciate the various levels"; I didn't get it.
4701 Add remark about HP-UX sh -x bug with stderr noted by Bob Proulx in
4702 <http://lists.gnu.org/archive/html/bug-coreutils/2006-06/msg00225.html>.
4703 (File Descriptors, Limitations of Usual Tools):
4704 Tone down the advice against renaming or removing open files.
4705 (Limitations of Usual Tools): Add a new section, on 'rm'.
4707 2006-06-26 Stepan Kasal <kasal@ucw.cz>
4709 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Use -lX11, not
4710 -lXt in LIBS, idea from Karsten Hopp; this was due since
4711 this change:
4713 2005-09-18 Paul Eggert <eggert@cs.ucla.edu>
4714 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Look for X11/Xlib.h
4715 and XrmInitialize rather than X11/Intrinsic.h and XtMalloc
4716 (which belong to Xt, not X itself). See Debian bug 327655.
4718 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4720 * configure.ac (AC_INIT): Bump to 2.60a.
4721 * NEWS: Update.
4723 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4725 Version 2.60.
4727 * configure.ac, NEWS: Update.
4729 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4731 * config/texinfo.tex: Sync from upstream.
4733 * bin/autom4te.in (handle_traces): Transform the `@S|@'
4734 quadrigraph correctly in traces.
4736 * NEWS, lib/Autom4te/C4che.pm, lib/autoconf/functions.m4:
4737 Fix typos.
4739 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Expand tests for
4740 datarootdir-related errors only if AC_DATAROOTDIR_CHECKED is
4741 not defined.
4742 * doc/autoconf.texi (Changed Directory Variables): New node,
4743 to document the whole `datarootdir' business a bit better.
4744 * NEWS: Update.
4745 * tests/torture.at (datarootdir workaround): Extend test.
4746 Prompted by report by Alexandre Julliard.
4748 2006-06-22 Paul Eggert <eggert@cs.ucla.edu>
4750 * lib/autoconf/c.m4 (_AC_PROG_CC_C89): Check for C89 incompatibility
4751 when using default mode of IBM C 6 for AIX. Problem and two-line
4752 fix reported by Larry Jones.
4754 2006-06-22 Alexandre Julliard <julliard@winehq.org>
4756 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Avoid warning
4757 about literal '${datarootdir}' if a definition is found in the
4758 output file.
4760 2006-06-20 Paul Eggert <eggert@cs.ucla.edu>
4762 * NEWS: Use "M4" rather than "m4" when appropriate.
4763 Problem reported by Eric Blake.
4764 * doc/autoconf.texi: Likewise.
4765 Use @acronym around BSD, GCC, and GNU when appropriate.
4766 (Why GNU M4): Renamed from "Why GNU m4".
4767 (Redefined M4 Macros): Mention that Posix
4768 m4wrap takes only 1 argument, but GNU M4 1.4.x takes more.
4769 (Buffer Overruns): Mention size_t and ptrdiff_t as alternatives
4770 to int.
4772 2006-06-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4774 * bin/autom4te.in (handle_output): Do not forbid the empty
4775 pattern.
4776 * tests/tools.at (autoconf: the empty token): New test.
4778 2006-06-20 Stepan Kasal <kasal@ucw.cz>
4780 * lib/m4sugar/m4sugar.m4 (m4_init): Merge the two m4_wrap
4781 calls, so that we do not care whether they are LIFO or FIFO;
4782 in the m4_wrap, do not check which diversion is the topmost
4783 one, just check that the stack is balanced at the end.
4784 * lib/m4sugar/m4sh.m4 (AS_INIT): We are going to change the
4785 base diversion forever--pop the previous diversion before
4786 opening the new one; consequently, remove the m4_wrap call.
4787 * lib/autotest/general.m4 (AT_INIT): Likewise.
4788 * tests/m4sugar.at: Do not use
4789 m4_wrap([m4_diversion_pop([..])]), for educational purposes.
4791 2006-06-19 Paul Eggert <eggert@cs.ucla.edu>
4792 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4794 * NEWS: Document that m4wrap/m4_wrap might not be LIFO.
4795 * doc/autoconf.texi (Redefined M4 Macros): Likewise.
4796 Rework example of m4wrap token-pasting trouble so that it doesn't
4797 care whether it's LIFO or FIFO.
4798 Fix some "contrary to"s that are awkward in English.
4800 2006-06-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4802 * lib/autoconf/types.m4 (_AC_TYPE_INT): Set `$ac_cv_c_int$1_t'
4803 to `yes' instead of `int$1_t' if the type is found, for more
4804 consistent configure output (where $1 is the number of bits).
4805 (_AC_TYPE_UINT): Likewise for `uint$1_t'.
4806 Suggested by Bruno Haible.
4808 * lib/autoconf/types.m4 (_AC_TYPE_UNSIGNED_INT): Solaris 2.5.1
4809 needs _UINT8_T and _UINT64_T defines as well, to avoid clashes
4810 with system headers. Report by Bruno Haible.
4812 2006-06-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4814 * config/config.guess, config/config.sub: Sync from upstream.
4816 * bin/Makefile.am (autoconf.in): Use `--melt' for autom4te,
4817 in order to avoid picking up an older installed frozen m4sh.m4f.
4818 Besides an outdated shell startup, this could have been created
4819 by an earlier M4 version with incompatible frozen file format.
4821 2006-06-16 Paul Eggert <eggert@cs.ucla.edu>
4823 * README: Recommend m4 1.4.4 instead of 1.4.3..
4824 * doc/autoconf.texi: Likewise.
4825 (Special Chars in Names): Say that $(.FOO) is portable, as
4826 suggested by Stepan Kasal.
4827 (Installation Directory Variables, Build Directories):
4828 (Automatic Remaking, Subdirectories, Fortran Compiler):
4829 (Making testsuite Scripts, Defining Directories):
4830 Quote variable usages better.
4831 (Making testsuite Scripts): Add clean-local rule to makefile
4832 snippet, by Eric Blake.
4833 (Installation Directory Variables): Fix table item font.
4834 Reword slightly to clarify. Generalize advice about
4835 not using special characters to include all file-related
4836 vars, not just VPATH.
4837 (Special Chars in Variables): Warn about special characters in
4838 $(srcdir) too.
4839 (Assignments): Clarify default-value example as suggested by
4840 Ralf Wildenhues in
4841 <http://lists.gnu.org/archive/html/autoconf-patches/2006-06/msg00072.html>.
4842 (Special Shell Variables): Note leading ./ or ../, as suggested
4843 by Eric Blake.
4844 (Limitations of Builtins): Under cd, warn about CDPATH.
4845 (The Make Macro MAKEFLAGS): Untabify. Problem reported by
4846 Ralf Wildenhues.
4848 2006-06-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4850 * doc/autoconf.texi (Configuration Actions): Remove duplicate
4851 `@var', for texi2html.
4852 (Systemology): Some more word wrapping, for DVI output.
4853 (autom4te Invocation): The short option for `--melt' is `-M',
4854 not `-m'.
4856 2006-06-15 Paul Eggert <eggert@cs.ucla.edu>
4858 * doc/autoconf.texi: More formatting and English tweaks,
4859 many suggested by Ralf Wildenhues.
4860 Reword to avoid "@code{...}'s" and the like, since it's ugly
4861 with Emacs info mode. discontents -> woes.
4862 Put a few "will"s back. time stamp -> timestamp.
4863 side-effect -> side effect.
4865 2006-06-14 Paul Eggert <eggert@cs.ucla.edu>
4867 * doc/autoconf.texi (Initializing configure, Shell Substitutions):
4868 Warn about $@ not persisting. Problem reported by Julien Danjou in
4869 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=372179>.
4870 (Special Chars in Names): Renamed from Leading _ in Macro Names.
4871 Mention other special chars, too.
4873 2006-06-14 Eric Blake <ebb9@byu.net>
4875 * doc/autoconf.texi (The Make Macro MAKEFLAGS): New node.
4877 2006-06-13 Paul Eggert <eggert@cs.ucla.edu>
4879 * doc/autoconf.texi: Some systematic minor improvements, as
4880 follows. Use "makefile" when talking about makefiles
4881 generally (which might be named "makefile" or "Makefile" or even
4882 "foo.mk"), "Makefile" when talking about a specific makefile
4883 called "Makefile". This unclutters the text from weird quotes
4884 (e.g., "`Makefile's" in info mode). Similarly, use "@var{foo}
4885 values" rather than "@var{foo}s" and similar constructs containing
4886 "}s". Use "Make rules" rather than "Makefile rules". Minor
4887 English-language improvements. Change the prefix "sub-" to "sub"
4888 and "re-" to "re".
4889 Put blank lines around examples more consistently.
4890 Avoid "rather" and "very" as intensifiers.
4891 Avoid "will" as an auxiliary.
4892 (Limitations of Make): Split this node into....
4893 (Portable Make, $< in Ordinary Make Rules, Failure in Make Rules):
4894 (Leading _ in Macro Names, Backslash-Newline-Newline):
4895 (Backslash-Newline Comments, Long Lines in Makefiles):
4896 (Macros and Submakes, The Make Macro SHELL, Comments in Make Rules):
4897 (obj/ and Make, make -k Status, VPATH and Make):
4898 (VPATH and Double-colon, $< in Explicit Rules):
4899 (Automatic Rule Rewriting, OSF/Tru64 Directory Magic):
4900 (Make Target Lookup, Single Suffix Rules, Timestamps and Make):
4901 New nodes, resulting from splitup of Limitations of Make.
4902 All cross-references changed. Raise the top node from
4903 a section to a chapter, and all subnodes accordingly.
4904 Redo the introductory wording to match the new organization.
4905 (Installation Directory Variables): Use an example that is
4906 closer to what Autoconf actually does. Mention that VPATH's
4907 value should not contain metacharacters or white space.
4908 (Fortran Compiler): Fix a VPATH bug in an example.
4909 (Leading _ in Macro Names): Mention that this problem is no longer
4910 of practical concern.
4911 (VPATH and Make): Reword the advice to make it clearer
4912 that Autoconf and Automake support VPATH in non-GNU make, but
4913 many packages have bugs in this area.
4914 ($< in Explicit Rules): Refer to Build Directories rather
4915 than using a (non-VPATH-safe) example.
4916 (Automatic Rule Rewriting): Mention the sort of disaster that
4917 can ensue with Solaris-style rule rewriting with VPATH.
4919 2006-06-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4921 * doc/install.texi (Compilers and Options): Weaken the
4922 suggestion to use GNU make for VPATH builds.
4924 * lib/autom4te.in (Automake-preselections): Add AM_PROG_CXX_C_O,
4925 AM_PROG_F77_C_O, AM_PROG_FC_C_O, AC_FC_SRCEXT, AC_FC_FREEFORM.
4927 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Fix M4 quotation
4928 in regular expression.
4930 2006-06-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4932 * doc/autoconf.texi (Installation Directory Variables):
4933 Drop extra @samp from `@table @samp' item.
4934 (Limitations of Usual Tools): Comment fix.
4935 Do not nest @samp just to point to other table items.
4936 (Writing testsuite.at) <AT_CHECK>: The second argument to
4937 `@dvar' is already @samp'ed.
4938 (Making testsuite Scripts) <AC_CONFIG_TESTDIR>: Likewise,
4939 do not use @var in the second argument.
4941 2006-06-07 Paul Eggert <eggert@cs.ucla.edu>
4943 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Look for
4944 $as_shell.exe too. Problem reported by Andreas Buening in
4945 <http://lists.gnu.org/archive/html/autoconf/2006-06/msg00038.html>.
4947 2006-06-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4949 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA): Work around
4950 `unused variable' compiler warning, for `-Wall -Werror'.
4951 Reported by Jaap Haitsma in
4952 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00012.html>.
4954 2006-06-06 Paul Eggert <eggert@cs.ucla.edu>
4956 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Remove core file, in
4957 case the compiler dumps core. Problem reported for
4958 OpenServer 5.0.7 by Tim Rice in
4959 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00019.html>.
4960 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE):
4961 Likewise.
4963 2006-06-06 Tim Rice <tim@multitalents.net>.
4965 * lib/freeze.mk: Quiet check-forbidden-patterns so the string
4966 "ERROR" only shows up in "make check" output if there is an
4967 error.
4969 2006-06-06 Eric Blake <ebb9@byu.net>
4971 * tests/tools.at (automatically allowed tokens): Fix typo.
4973 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
4975 * NEWS: Don't blame non-GNU VPATH compatibility issues on Automake.
4977 * doc/autoconf.texi (Integer Overflow): Mention that INT_MIN % -1
4978 typically overflows on x86 CPUs, even though the C standard
4979 requires otherwise.
4981 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4983 * configure.ac (AC_INIT): Bump to 2.59e.
4984 * NEWS: Update.
4986 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4988 Version 2.59d.
4990 * config/texinfo.tex: Sync from upstream.
4992 * bin/autoreconf.in: Trace `LT_CONFIG_LTDL_DIR'; if it has been
4993 seen, invoke libtoolize with `--ltdl' argument.
4994 * lib/autom4te.in (Autoreconf-preselections): Adjust.
4995 * NEWS: Update.
4996 Suggested by Eric Blake.
4998 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
5000 * NEWS: Whoops! AC_FUNC_STRNLEN isn't obsolescent. Problem
5001 reported by Ralf Wildenhues.
5002 * doc/autoconf.texi (AC_FUNC_STRNLEN): Likewise.
5004 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5006 * THANKS: Update.
5008 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
5010 * doc/autoconf.texi: Modernize some of the references to Solaris.
5012 2006-06-05 Stepan Kasal <kasal@ucw.cz>
5014 * lib/m4sugar/m4sugar.m4 (m4_require): Modify the error
5015 message issued by AC_REQUIRE.
5016 * tests/m4sugar.at: Check m4_require's error message.
5017 * tests/base.at: Check AC_REQUIRE's error message.
5018 * tests/local.at (AT_CHECK_M4): New macro, almost identical
5019 to...
5020 (AT_CHECK_AUTOM4TE): ... which is now a thin wrapper around
5021 AT_CHECK_M4.
5022 (AT_CHECK_AUTOCONF): Use AT_CHECK_M4; no longer support
5023 `expout' as the last parameter.
5024 * tests/tools.at: Adapt to the above change.
5026 2006-06-04 Stepan Kasal <kasal@ucw.cz>
5028 * doc/autoconf.texi (Limitations of Usual Tools): Correct
5029 information about race-free implementations of mkdir.
5031 2006-06-04 Eric Blake <ebb9@byu.net>
5033 * bin/autoreconf.in (help): Document M4 environment variable.
5034 * bin/autoconf.as (Usage): Likewise.
5035 * bin/autom4te.in (help): Likewise.
5036 * doc/autoconf.texi (autom4te Invocation): Likewise.
5038 2006-06-04 Paul Eggert <eggert@cs.ucla.edu>
5040 * NEWS: GNU make now recommended for VPATH builds.
5041 Mention that some macros are now documented to be obsolescent.
5042 * doc/autoconf.texi:
5043 Prefer "current" to "modern" to describe
5044 currently-used (albeit perhaps old-fashioned) hosts.
5045 Mention which ancient features no longer need to be worried about.
5046 setgid -> set-group-ID
5047 setuid -> set-user-ID (these are the Posix terms)
5048 Fix some misuses of "only".
5049 (AC_C_BACKSLASH_A, AC_C_CONST, AC_C_PROTOTYPES):
5050 (AC_C_STRINGIZE, AC_C_VOLATILE, AC_FUNC_CLOSEDIR_VOID):
5051 (AC_FUNC_GETPGRP, AC_FUNC_LSTAT, AC_FUNC_MEMCMP):
5052 (AC_FUNC_SELECT_ARGTYPES, AC_FUNC_SETPGRP):
5053 (AC_FUNC_SETVBUF_REVERSED, AC_FUNC_STAT, AC_FUNC_STRFTIME):
5054 (AC_FUNC_STRNLEN, AC_FUNC_UTIME_NULL, AC_FUNC_VPRINTF):
5055 (AC_HEADER_DIRENT, AC_HEADER_STAT, AC_HEADER_STDC):
5056 (AC_HEADER_SYS_WAIT, AC_HEADER_TIME, AC_ISC_POSIX):
5057 (AC_PROG_GCC_TRADITIONAL, AC_STRUCT_TM):
5058 Mention that these macros are obsolescent.
5059 (Installation Directory Variables): shall -> should
5060 (File Descriptors): Mention that 0, 1, 2 might get reopened.
5061 Mention that it's now safe to use 3 and 4.
5062 (Limitations of Usual Tools): cp -r is now specified by Posix.
5063 Omit longwinded and obsolescent discussion of cp -f.
5064 Modernize discussion of expr, ls.
5065 (Limitations of Make): Modernize discussion of VPATH builds.
5066 Mention $? as a workaround in some cases.
5067 * doc/install.texi (Basic Installation):
5068 Mention "./configure; make; make install" first. Be more
5069 specific about why this file is generic. Remove unnecessary
5070 parens. Remove misleading "only". Remove obsolete advice
5071 about csh. Don't say "configure" takes awhile; say it
5072 might take a while. Suggest CFLAGS=-g rather than CFLAGS=-O2,
5073 and CC=c99 rather than CC=c89, as these are blessed by current
5074 Posix. Recommend GNU make if doing a VPATH build.
5076 2006-06-03 Paul Eggert <eggert@cs.ucla.edu>
5078 * doc/autoconf.texi: Use a consistent style "$ @kbd{...}" for
5079 examples involving shell prompts.
5081 2006-06-02 Stepan Kasal <kasal@ucw.cz>
5082 and Paul Eggert <eggert@cs.ucla.edu>
5084 * doc/autoconf.texi (Here-Documents): Add details about the
5085 pre-ksh93g bug. Reword slightly to make it clearer. Consistently
5086 use "here-documents" instead of "here documents".
5088 2006-06-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5090 * config/texinfo.tex, doc/standards.texi: Sync from upstream.
5092 2006-06-01 Paul Eggert <eggert@cs.ucla.edu>
5094 * doc/autoconf.texi (File System Conventions): Warn about ":"
5095 anywhere in directory names.
5097 2006-05-31 Paul Eggert <eggert@cs.ucla.edu>
5099 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be even more conservative
5100 about quoting the case statement, just in case.
5101 * doc/autoconf.texi (Here-Documents): Mention that the ksh bug
5102 was fixed in ksh93g; reported by Ralf Wildenhues.
5104 2006-05-31 Stepan Kasal <kasal@ucw.cz>
5106 * doc/autoconf.texi (System Services): Do not document
5107 overriding EXEEXT via ac_cv_exeext=ext.
5108 (Particular Programs) <AC_PROG_MKDIR_P>:
5109 Document that ${MKDIR_P} understands --.
5110 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Improve the
5111 comment.
5113 2006-05-31 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5115 * lib/m4sugar/m4sh.m4 (_AS_DIRNAME_PREPARE): Guard against test
5116 argument with leading hyphen. Problem reported by Paul Eggert.
5118 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
5120 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be more conservative
5121 about quoting ac_try: quote all of it, if any of it seems suspicious.
5122 This means we don't have to worry about ${ or sed any more.
5123 Also, double-quote the case statement, to work around misuses via
5124 underquoting as reported by Ralf Wildenhues in
5125 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00169.html>.
5126 (_AC_EVAL_STDERR): Revert, since evidently some packages rely on this
5127 undocumented and dangerous macro.
5128 Problem reported by Ralf Wildenhues in
5129 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00168.html>.
5131 2006-05-31 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5133 * lib/m4sugar/m4sh.m4 (_AS_DIRNAME_PREPARE): Check whether
5134 `dirname -- /' returns `/', for SunOS dirname scripts that escaped.
5135 Report by Sam Sirlin <sam@kalessin.jpl.nasa.gov>.
5137 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
5139 * lib/autoconf/general.m4: Revert AC_TRY_EVAL and AC_TRY_COMMAND,
5140 since evidently some packages rely on the old, broken behavior.
5141 Problem reported by Ralf Wildenhues in
5142 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00160.html>.
5143 (AC_TRY_EVAL, AC_TRY_COMMAND, _AC_EVAL): Go back to the
5144 pre-2006-05-26 definitions, but leave in the comments that
5145 these macros are dangerous and should not be used.
5146 (_AC_DO_ECHO): Renamed from _AC_EVAL_ECHO. All callers changed.
5147 (_AC_DO): Renamed from _AC_EVAL. All callers changed.
5148 (_AC_DO_STDERR): Renamed from _AC_EVAL_STDERR. All callers changed.
5149 (_AC_DO_VAR): Renamed from AC_TRY_EVAL.
5150 (_AC_DO_TOKENS): Renamed from AC_TRY_COMMAND.
5152 2006-05-29 Paul Eggert <eggert@cs.ucla.edu>
5154 * lib/autoconf/status.m4 (AC_OUTPUT_MAKE_DEFS): Rewrite to avoid
5155 the use of 'tr', since this is our only use of 'tr'.
5157 2006-05-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5158 and Paul Eggert <eggert@cs.ucla.edu>
5160 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE):
5161 Don't assume 'grep' works on long lines, since AIX grep doesn't.
5163 2005-05-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5165 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Do not use `grep' on
5166 the output file in the `${datarootdir}' test.
5168 2005-05-28 Stepan Kasal <kasal@ucw.cz>
5169 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5171 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If we have not seen
5172 mention of `datarootdir' in the input file(s), but literal
5173 `${datarootdir}' in the output file, and we haven't warned yet,
5174 then warn as well: the user may have (erroneously) used
5175 `AC_SUBST([mydatadir], [$datadir/my])' instead of the correct
5176 `AC_SUBST([mydatadir], ['${datadir}/my'])'.
5177 * tests/torture.at (datarootdir workaround): Extend this test.
5178 * NEWS: Update.
5180 2006-05-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5181 and Paul Eggert <eggert@cs.ucla.edu>
5183 * doc/autoconf.texi (autoheader Invocation): The first argument to
5184 `AC_DEFINE_UNQUOTED' need not be a literal. Mention the
5185 alternatives and clear up the language a bit.
5187 2006-05-27 Paul Eggert <eggert@cs.ucla.edu>
5189 * NEWS: Reword notice for AC_TRY_COMMAND, AC_TRY_EVAL,
5190 ac_config_guess, ac_config_sub, ac_configure.
5191 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
5192 Fix typo that prevented an unnecessary space from being removed.
5193 Problems reported by Ralf Wildenhues in:
5194 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00143.html
5196 2006-05-26 Paul Eggert <eggert@cs.ucla.edu>
5198 * doc/autoconf.texi (Particular Programs, Limitations of Usual Tools):
5199 Use better wording to talk about AC_PROG_MKDIR_P's thread-safety.
5200 Don't use the term "thread-safe" to talk about mkdir race
5201 conditions, since the problem is more a process than a thread
5202 issue. Problem reported by Stepan Kasal in:
5203 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00088.html
5204 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Use code that mimics
5205 the test for 'install' more closely. Look at MKDIR_P first.
5206 Look in the PATH, and at /opt/sfw/bin.
5207 Look for a 'gmkdir' program as well (Solaris 10 /opt/sfw/bin/gmkdir).
5208 Don't bother to try mkdir -p, since we already check mkdir --version;
5209 just look at the version number. (There's no easy way to check
5210 for race-free implementations.)
5211 * tests/tools.at (autoconf: subdirectories): Adjust to above
5212 changes, since MKDIR_P now might end in "/mkdir -p".
5214 * doc/autoconf.texi (autoheader Invocation): Mention that the
5215 first arg of AC_DEFINE_UNQUOTED must be a literal.
5216 Problem reported by Ben Pfaff in
5217 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00090.html>.
5219 * NEWS: Mention that AC_TRY_COMMAND and AC_TRY_EVAL may be removed.
5220 * doc/autoconf.texi (Special Chars in Variables): New section.
5221 (Preset Output Variables): Warn about special chars in CPPFLAGS.
5222 (Installation Directory Variables): Quote $(datadir) better.
5223 (Limitations of Builtins): Describe some of eval's trickiness.
5225 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Simplify quoting.
5226 * lib/autoconf/fortram.m4 (_AC_PROG_FC_V_OUTPUT): Likewise.
5227 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Put leading space
5228 in front of every arg, not just trailing args. Quote apostrophes.
5229 (_AC_EVAL_ECHO): New macro.
5230 (_AC_EVAL, AC_EVAL_STDERR): Use it. Quote arg of eval.
5231 (AC_TRY_EVAL, AC_TRY_COMMAND): Mention that these macros might get
5232 removed.
5233 (_AC_LINK_IFELSE): Use proper rule for shell continuation lines,
5234 exposed by quoting of eval argument. Put the command on line line
5235 so it logs better.
5236 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): Use eval more safely.
5237 (_AC_PATH_X, AC_PATH_X): Quote more safely.
5238 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Use eval more safely.
5239 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Don't use eval.
5240 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Minor style change.
5241 Handle special chars in prefix, ac_srcdir, ac_aux_dir.
5242 Use eval more safely.
5243 (_AC_OUTPUT_CONFIG_STATUS): Adjust to above changes.
5244 * lib/m4sugar/m4sh.m4 (AS_VAR_GET): Note that this API needs
5245 to be replaced.
5246 * tests/base.at (AC_TRY_COMMAND): Use proper rule for shell continuation
5247 lines, exposed by quoting of eval argument.
5249 2006-05-26 Stepan Kasal <kasal@ucw.cz>
5250 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5252 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Drop the
5253 initialization of `ac_cv_exeext', do not override it if it was
5254 already set, unless it was set to `no', for compatibility with
5255 Autoconf-2.13, and comment this.
5256 Do not export `ac_cv_exeext', Libtool hasn't needed this for years.
5257 (_AC_COMPILER_EXEEXT_DEFAULT): Likewise, do not export it.
5258 (_AC_COMPILER_EXEEXT_WORKS, _AC_COMPILER_EXEEXT_CROSS): Typos.
5259 * doc/autoconf.texi (Compilers and Preprocessors) <EXEEXT>:
5260 Document that this test may be overridden by setting
5261 `ac_cv_exeext'.
5263 2006-05-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5265 Revert these two patches:
5267 2006-04-06 Eric Blake <ebb9@byu.net>
5268 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_O): Inside cache
5269 check, s/ac_exeext/ac_cv_exeext/. Fixes regression introduced
5270 2006-04-01.
5272 2006-04-01 Stepan Kasal <kasal@ucw.cz>
5273 Clean up _AC_COMPILER_EXEEXT* macros.
5274 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't try to
5275 detect exeext, it will be done by _AC_COMPILER_EXEEXT_O; just set
5276 ac_file to the name of the default output file and call
5277 _AC_COMPILER_EXEEXT_WORKS. Move the definition of ac_files and the
5278 initial `rm' of the candidate files...
5279 (_AC_COMPILER_EXEEXT): ... here and simplify them. Moreover, use
5280 the same list in subsequent `rm' calls, and for the temporary
5281 redefinition of ac_clean_files; call _AC_COMPILER_OBJEXT at the end,
5282 and don't call the other _AC_COMPILER_EXEEXT_* macros directly, use...
5283 (_AC_COMPILER_EXEEXT_TESTS): ... this new macro.
5284 (_AC_COMPILER_EXEEXT_O): Don't export ac_cv_exeext, it's not needed (or
5285 no longer needed) by libtool. Make it a cache check.
5286 (_AC_COMPILER_EXEEXT_CROSS): Remove the comment, it was obviously
5287 copied here by mistake.
5288 (AC_NO_EXECUTABLES): Redefine _AC_COMPILER_EXEEXT_TESTS, not
5289 _AC_COMPILER_EXEEXT.
5290 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX, AC_PROG_OBJC): Do not call
5291 _AC_COMPILER_OBJEXT directly.
5292 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
5294 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5296 * doc/autoconf.texi (Limitations of Usual Tools) < sed (`t')>:
5297 Fix description of how the buggy `sed' works.
5299 2006-05-25 Noah Misch <noah@cs.caltech.edu>
5301 Sync from Automake:
5303 * lib/Autom4te/XFile.pm (lock): Allow EOPNOTSUPP, besides
5304 ENOLCK. Only mention `make -j' when applicable. Only raise
5305 fatal errors when `make -j' is involved. Improve error message.
5307 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5309 * doc/autoconf.texi (Here-Documents): We now know more about
5310 the variable expansion in here documents bug.
5311 Thanks to Tim Rice and Stepan Kasal.
5313 * doc/autoconf.texi (Making testsuite Scripts): Add an example
5314 how to use TESTSUITEFLAGS. Suggested by Eric Blake.
5316 2006-05-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5318 * tests/autotest.at (Multiline command from M4 expansion):
5319 No failure to be expected if the shell quotes newlines in
5320 commands in the `set -x' output. Report by Tim Rice.
5321 * THANKS: Update.
5323 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
5325 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Don't use shell
5326 expansion in the here-documents used by config.status, as that
5327 runs afoul of the Korn shell version M-12/28/93d bug described in
5328 the Autoconf manual, and this in turn causes a Coreutils 5.95 build to
5329 fail as described by Tim Rice and diagnosed by Ralf Wildenhues in
5330 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00082.html>.
5332 2006-05-23 Jim Meyering <jim@meyering.net>
5334 * lib/autoconf/functions.m4 (AC_FUNC_LSTAT_FOLLOWS_SLASHED_SYMLINK):
5335 Fix typo introduced with 2006-04-02 change. It reversed the sense
5336 of the test.
5338 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
5340 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Simplify ac_dA and
5341 ac_dB slightly, to save bytes in the script.
5342 Max out at 50 lines, rather than 96; this is more likely
5343 (though not guaranteed) to avoid obscure 'sed' failures.
5345 2006-05-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5347 * lib/autotest/general.m4 (AT_INIT): UnixWare `tr' may interpret
5348 `tr -d -' as bad option argument. Work around this by deleting
5349 an unrelated character.
5350 Report by Tim Rice <tim@multitalents.net>.
5352 2006-05-22 Paul Eggert <eggert@cs.ucla.edu>,
5353 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
5354 Stepan Kasal <kasal@ucw.cz>
5356 * doc/autoconf.texi (Particular Programs): Do not promise that
5357 we always prefer the GNU version of the program, and that we
5358 search according to PATH; both rules can have exceptions.
5359 Update description of AC_PROG_GREP, AC_PROG_EGREP, AC_PROG_FGREP,
5360 AC_PROG_SED. Move descriptions of limitations
5361 to the Limitations of Usual Tools section.
5362 (Limitations of Usual Tools) <sed>: Mention script length
5363 limitations with Solaris /usr/ucb/sed.
5364 <grep>: Fix wording for empty alternative. Mention that -c and
5365 -l should not be combined, and that -E and -F should not be
5366 combined.
5368 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
5369 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5371 * lib/autoconf/programs.m4 (AC_PROG_SED): Catch script length
5372 limits in Solaris 8 /usr/ucb/sed by testing a long script.
5374 2006-05-22 Stepan Kasal <kasal@ucw.cz>
5376 * doc/autoconf.texi (Defining Symbols): Literal parameter of
5377 AC_DEFINE is now passed to m4_pattern_allow.
5378 * NEWS: Mention that; likewise for AC_SUBST.
5379 * lib/autoconf/general.m4 (AC_DEFINE_TRACE_LITERAL): Pass
5380 the parameter to m4_pattern_allow.
5381 * tests/tools.at: Add a check for that.
5383 2006-05-22 Stepan Kasal <kasal@ucw.cz>
5385 * lib/autoconf/status.m4: Fix typos.
5387 2006-05-21 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5389 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Remove
5390 only the files that this macro generates.
5392 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
5394 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: For
5395 the HP-UX sed limitation of 99 commands, labels do not count.
5396 * lib/autoconf/status.m4 (_AC_SED_CMD_LIMIT): Mention that
5397 in the comment.
5398 (_AC_OUTPUT_HEADER): Revert the change from 2006-05-19.
5400 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
5402 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT):
5403 Import the following fix from coreutils:
5405 2006-01-13 Jim Meyering <jim@meyering.net>
5407 Invoke AC_CHECK_FUNCS(getmntent) unconditionally so that tests of
5408 $ac_cv_func_getmntent (e.g., in gl_LIST_MOUNTED_FILE_SYSTEMS) need
5409 not double-quote uses of that variable, to accommodate the rare
5410 case in which getmntent is available in none of the libraries
5411 checked. This happens at least on FreeBSD 5.0.
5413 2006-05-20 Paul Eggert <eggert@cs.ucla.edu>
5415 * lib/autoconf/general.m4 (AC_CONFIG_AUX_DIRS): Bring back
5416 ac_config_guess, ac_config_sub, and ac_configure, since evidently
5417 some other programs unwisely rely on these undocumented vars.
5418 But put in warning comments about them.
5419 Problem reported by Ralf Wildenhues in
5420 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00068.html>.
5421 * NEWS: Document that these variables are intended to go away.
5423 2006-05-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5425 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): Require AC_PROG_CXX,
5426 and set the language to C++ (analogous to the equivalent Fortran
5427 tests).
5429 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): New macro.
5430 * doc/autoconf.texi (C++ Compiler): Document it.
5431 * lib/autoconf/fortran.m4 (_AC_PROG_FC_C_O): Adjust comment.
5432 * NEWS: Update.
5434 2006-05-19 Paul Eggert <eggert@cs.ucla.edu>
5436 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Fix off-by-one bug
5437 that caused config.status to generate 100-command sed scripts; the
5438 portable limit is 99.
5440 2006-05-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5442 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Name temporary
5443 variable `ac_d' instead of `d' to avoid infringing namespace.
5444 Report by Ralf Menzel.
5446 2006-05-18 Paul Eggert <eggert@cs.ucla.edu>
5448 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Don't prepend
5449 $ac_top_build_prefix to $MKDIR_P if it's just 'mkdir -p'.
5450 * tests/tools.at (autoconf: subdirectories): New test, taken from
5451 the corresponding problem report by Ralf Wildenhues in:
5452 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00053.html
5454 * lib/autoconf/functions.m4 (AC_REPLACE_FNMATCH, AC_FUNC_FNMATCH_GNU):
5455 Quote some uses of shell variables if they might suffer unexpected
5456 globbing. This doesn't fix all instances of quoting problems that
5457 I found, just the easy ones that look safe.
5458 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR, _AC_INIT_HELP):
5459 (AC_CONFIG_AUX_DIR, AC_CONFIG_AUX_DIR_DEFAULT, AC_CONFIG_AUX_DIRS):
5460 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST, AC_CANONICAL_TARGET):
5461 (AC_CACHE_LOAD, AC_CACHE_SAVE): Likewise.
5462 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF, _AC_PATH_X_DIRECT): Likewise.
5463 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Likewise.
5464 * lib/autoconf/status.m4 (_AC_OUTPUT_LINK, _AC_OUTPUT_SUBDIRS):
5465 Likewise.
5466 * lib/autotest/general.m4 (_AC_INIT_PARSE_ARGS): Likewise.
5467 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Likewise.
5469 2006-05-18 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5471 * bin/autoreconf.in ($help): Reword according to the manual.
5472 Suggested by Olly Betts.
5474 2006-05-17 Olly Betts <olly@survex.com> (tiny change)
5475 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5477 * bin/autoreconf.in: Pass the directory argument to
5478 `require_configure_ac'. Fix comment.
5479 * tests/torture.at (Configuring subdirectories): Expose this.
5480 Reported by Olly Betts.
5482 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5484 * lib/Automake/Configure_ac.pm, lib/Automake/Channels.pm,
5485 lib/Automake/FileUtils.pm, lib/Automake/Struct.pm: Sync from
5486 Automake as follows:
5488 * lib/Autom4te/Configure_ac.pm (find_configure_ac): Use
5489 `$configure_in' instead of `configure.in', to preserve
5490 directory component.
5492 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5494 * config/config.guess, config/config.sub, config/texinfo.tex,
5495 doc/make-stds.texi, doc/standards.texi: Sync from upstream.
5497 2006-05-14 Paul Eggert <eggert@cs.ucla.edu>
5499 * lib/autoconf/headers.m4 (AC_HEADER_STDBOOL): Fix overly-picky
5500 test for C99 conformance; (bool) 0.5 is an integer constant
5501 expression, but (bool) -0.5 is not. Problem reported by Fedor
5502 Sergeev in <http://forum.sun.com/jive/thread.jspa?threadID=96202>.
5504 2006-05-13 Paul Eggert <eggert@cs.ucla.edu>
5506 * doc/autoconf.texi (Particular Programs): AC_PROG_MKDIR_P now
5507 sets MKDIR_P, not mkdir_p, to avoid collisions with Automake.
5508 Warn about obsolete install-sh files. Remove stray sentence
5509 fragment and fix cross reference.
5510 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Don't insist on
5511 install -d; this undoes the 2006-05-10 change.
5512 (MKDIR_P): Mark with AN_MAKEVAR.
5513 (AC_PROG_MKDIR_P): Fall back on $ac_install_sh, not $INSTALL, so
5514 that we don't require $INSTALL to be thread-safe. Move comments
5515 out of generated code. Require AC_CONFIG_AUX_DIR_DEFAULT instead
5516 of AC_PROG_INSTALL. Output a message saying that we're checking
5517 mkdir -p. Set MKDIR_P rather than mkdir_p. Do special magic for
5518 MKDIR_P instead of AC_SUBST.
5519 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE, _AC_OUTPUT_CONFIG_STATUS):
5520 Special magic for MKDIR_P, too.
5521 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Remove comment that defeated
5522 a dnl.
5523 * tests/local.at (AT_CHECK_ENV): mkdir_p -> MKDIR_P.
5525 2006-05-11 Paul Eggert <eggert@cs.ucla.edu>
5527 Sync from Automake, as follows:
5529 2006-05-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5530 * config/install-sh: Initialize IFS, so field splitting isn't
5531 turned off later.
5532 * config/mkinstalldirs: Likewise.
5533 * config/missing: Remove superfluous quotes. Replace all uses of
5534 `[' by `test', for consistency, and for..
5535 * config/missing (sed_minuso, sed_output): New variables.
5536 (autom4te, help2man, makeinfo): Use them. Unifies detection of
5537 `-o FILE', `--output FILE', `--output=FILE', stricter regex.
5538 Fixes `missing' to detect `--output' for help2man. Fixes
5539 PR automake/483. Report by Dennis J. Linse.
5540 (autom4te): Document in `missing --help'.
5542 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
5544 * NEWS: New macro AC_PROG_MKDIR_P. AS_MKDIR_P is now more robust.
5545 * config/install-sh: Don't use 'path' to talk about file names,
5546 as per GNU coding standards. Close a race condition reported by Ralf
5547 Wildenhues and Stepan Kasal. There is still a race condition
5548 on hosts that predate Posix 1003.1-1992, but we can't help this.
5549 Don't mishandle weird characters like space on pre-Posix hosts.
5550 Invoke mkdir at most once per dir arg on pre-Posix hosts.
5551 * doc/autoconf.texi (Programming in M4sh): Cross-reference to
5552 AC_PROG_MKDIR_P from AS_MKDIR_P.
5553 (Limitations of Usual Tools): Cross-reference to AC_PROG_MKDIR_P
5554 from mkdir. Mention that Autoconf 2.60 install-sh is safe but
5555 earlier editions are not (including Automake 1.8.3).
5556 Do not suggest mkinstalldirs for thread-safety.
5557 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Insist on an 'install'
5558 that understands -d, so that AC_PROG_MKDIR_P can fall back on $INSTALL.
5559 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Make it more robust in the
5560 presence of special characters and race conditions.
5561 * tests/local.at (AT_CHECK_ENV): Add mkdir_p to the list of variables
5562 in Autoconf's name space.
5564 2006-05-10 Bruno Haible <bruno@clisp.org>
5565 and Paul Eggert <eggert@cs.ucla.edu>
5567 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): New macro, taken
5568 from Automake with minor changes.
5569 * doc/autoconf.texi (Particular Programs): Document AC_PROG_MKDIR_P.
5571 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
5573 * config/install-sh: Update to Automake CVS version, as follows:
5574 2006-04-25 Stepan Kasal <kasal@ucw.cz>
5575 * lib/install-sh: Simplify the expr implementation of dirname.
5576 2006-04-24 Paul Eggert <eggert@cs.ucla.edu>
5577 * lib/install-sh: Handle --, and diagnose unknown options.
5579 2006-05-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5581 * tests/Makefile.am (AUTOTEST): Use `$(MY_AUTOM4TE)' instead of
5582 `./autom4te' to create `./testsuite', since the `all' target
5583 will ensure its presence, but `installcheck' should not create
5584 the uninstalled wrappers.
5586 * tests/torture.at (Unusual Automake input files): Skip if we
5587 detect automake < 1.8.
5589 2006-05-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5591 * lib/autoconf/c.m4 (AC_PROG_CC_STDC): If ac_cv_prog_cc_stdc
5592 is set to `no', then that overrides and sets ac_cv_prog_cc_c89
5593 and ac_cv_prog_cc_c99 to `no', for backward compatibility.
5594 * NEWS: Update.
5596 2006-05-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5598 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Take care not to
5599 munge (multiple) white space and other oddities.
5600 * tests/torture.at (AT_CHECK_AC_ARG_VAR): Make sure to M4-escape
5601 single quotes in variable assignment.
5602 (AC_ARG_VAR, configure invocation): Adjust tests to expose this
5603 and similar failures by adding multiple spaces, tabs, and other
5604 special characters.
5605 Report and different test suggested by Francesco Romani
5606 <fromani@gmail.com> and Andrew Church <achurch@achurch.org>.
5608 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): When we escape
5609 single quotes, we only need to search for single quotes; this
5610 both simplifies the search pattern, and makes us less
5611 susceptible to `echo' variations for arguments not containing
5612 single quotes.
5613 (_AC_ARG_VAR_VALIDATE): Likewise.
5615 2006-05-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5617 * doc/autoconf.texi (Special Shell Variables) <IFS>: Document
5618 `$*' and IFS concatenation issue with traditional shells and
5619 bash-2.04. Report by Seanster@Seanster.com.
5621 2006-05-03 Bruno Haible <bruno@clisp.org>
5623 * doc/autoconf.texi (Limitations of Usual Tools): Identify more
5624 precisely which Mac OS X versions have the od problem.
5626 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
5628 * doc/autoconf.texi: Use @option systematically.
5630 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
5631 and Bruno Haible <bruno@clisp.org>
5633 * doc/autoconf.texi (Limitations of Usual Tools): Add a paragraph
5634 about 'od'.
5635 (Integer Overflow): Mention the special case of integer division
5636 overflow.
5638 2006-05-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5640 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Cater for
5641 traditional shells like the Solaris one that do not use the
5642 first IFS character for assembling `$*'.
5643 Prompted by a related report from autoconf_bug@nro.ca.
5645 2006-05-01 Paul Eggert <eggert@cs.ucla.edu>
5646 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5648 * doc/autoconf.texi (Limitations of Builtins, Limitations of Make):
5649 Mention more problems with the -e option.
5651 2006-04-30 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5653 * NEWS: Typo.
5654 * doc/autoconf.texi (Systemology): Mention the Heirloom Project.
5656 * doc/autoconf.texi (Introduction, Pointers): Use `@/' liberally
5657 in URLs to improve DVI formatted output (requires texinfo 4.6).
5658 (System Services, Systemology, Shellology): Likewise.
5659 (Limitations of Usual Tools): Rewrite Mac OS X example for nicer
5660 output.
5662 * doc/autoconf.texi (Fortran Compiler): Do not use `@ovar' in
5663 continuous text.
5664 (Runtime): Fix macro argument names to match description:
5665 `action-if-found' -> `action-if-true' and similarly.
5666 (Obsolete Macros): Likewise.
5667 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE): Likewise.
5668 (AC_COMPILE_IFELSE, AC_TRY_COMPILE, _AC_LINK_IFELSE)
5669 (AC_LINK_IFELSE, AC_TRY_LINK, AC_COMPILE_CHECK): Likewise.
5671 2006-04-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5673 * doc/autoconf.texi (Limitations of Make): Clean up markup.
5675 * ChangeLog: Typo.
5676 * doc/autoconf.texi (Portable Shell): Allow wrapped URLs, for
5677 DVI output.
5679 2006-04-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

5682 /bin/sh set unsorted output.
5683 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): Adjust.
5684 * tests/local.at: Likewise.
5686 2006-04-26 Paul Eggert <eggert@cs.ucla.edu>
5688 * doc/autoconf.texi (Portable C and C++, Varieties of Unportability):
5689 (Integer Overflow, Null Pointers, Buffer Overruns):
5690 (Floating Point Portability, Exiting Portably): New sections.
5691 (Writing Test Programs): Fix some langauge. Recommend exiting
5692 with status 1, not merely nonzero. Clarify exit declaration.
5693 (Run Time): Move C exit status stuff to new Exiting Portably section.
5694 (Systemology): Mention Posix and levenez. Update v7 reference.
5695 (Portable Shell): Mention the Posix shell.
5697 2006-04-25 Stepan Kasal <kasal@ucw.cz>
5699 * bin/autoconf.as (me): Replace by as_me.
5701 2006-04-25 Paul Eggert <eggert@cs.ucla.edu>
5703 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Don't use AS_ERROR,
5704 since as_me isn't set yet.
5706 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
5708 Prepare for deprecation of AS_BASENAME and AS_DIRNAME, and fix
5709 a few minor bugs in this area.
5711 * doc/autoconf.texi (Programming in M4sh): Comment out the
5712 documentation of AS_BASENAME, for now.
5713 (Shell Substitutions): Do not use AS_DIRNAME in an example.
5714 (Limitations of Builtins) <basename>: Do not refer to
5715 AS_BASENAME.
5716 * bin/autoconf.as (me): Don't use AS_BASENAME.
5717 (dir): Remove the unused variable.
5718 * lib/m4sugar/m4sh.m4 (_AS_DETECT_REQUIRED): Renamed from
5719 AS_DETECT_REQUIRED. All uses changed.
5720 (_AS_DETECT_SUGGESTED): Renamed from AS_DETECT_SUGGESTED.
5721 All uses changed.
5722 (_AS_DETECT_BETTER_SHELL): Put ;; at the end of a case.
5723 (AS_BASENAME): Use "basename --" to protect against leading "-".
5724 (_AS_BASENAME_EXPR): Renamed from AS_BASENAME_EXPR. All uses changed.
5725 (_AS_BASENAME_SED): Renamed from AS_BASENAME_SED. All uses changed.
5726 (_AS_BASENAME_PREPARE): Reject implementations that cannot handle "--".
5727 (_AS_DIRNAME_PREPARE): Likewise.
5728 (_AS_DIRNAME_EXPR): Renamed from AS_DIRNAME_EXPR. All uses changed.
5729 (_AS_DIRNAME_SED): Renamed from AS_DIRNAME_SED. All uses changed.
5730 (AS_DIRNAME): Use "dirname --".
5732 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
5734 * doc/autoconf.texi (Runtime): Renamed from "Run Time". All uses
5735 of "run time" and "run-time" changed to "runtime", for consistency.
5736 * lib/autoconf/fortran.m4: Likewise (in comment).
5737 * lib/autoconf/functions.m4: Likewise.
5738 * lib/autoconf/general.m4: Likewise.
5739 * lib/autoconf/headers.m4: Likewise.
5741 * doc/autoconf.texi (Run Time): Document the exit status situation
5742 with more accuracy and detail.
5744 2006-04-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5746 * doc/autoconf.texi (Introduction): The GNU Autoconf Macro
5747 Archive is not officially `GNU' any more. Update URL.
5748 (Defining Directories): Likewise
5749 * lib/autoconf/c.m4 (AC_C_RESTRICT): Update URL.
5751 2006-04-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5753 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Remove the leading
5754 newline from the `trap' code to finish `config.log'; the NetBSD
5755 /bin/sh resets the exit status after an empty command, as
5756 documented in doc/autoconf.texi.
5757 Reported by Dalibor Topic <robilad@kaffe.org>.
5759 2006-04-19 Paul Eggert <eggert@cs.ucla.edu>
5761 * doc/autoconf.texi (C Compiler): Clarify AC_C_TYPEOF.
5762 Suggested by Bruno Haible.
5764 2006-04-18 Paul Eggert <eggert@cs.ucla.edu>
5766 * configure.ac (ac_cv_sh_n_works): Don't try to test for it, since
5767 some shells (e.g., Solaris 8 /bin/sh) implement it verrrry slowly.
5768 Instead, just list the shells that we know work.
5769 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Remove 2nd arg. All uses
5770 changed. Be more cautious about the _cv_ variable.
5771 * tests/tools.at (Syntax of the shell scripts): Check the
5772 _cv_ variable once, at first, to avoid an internal autoconf error
5773 when sh -n does not work.
5775 2006-04-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5777 * lib/Autom4te/FileUtils.pm: Sync from Automake.
5779 2006-04-16 Paul Eggert <eggert@cs.ucla.edu>
5781 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Don't
5782 use ">&-" since we're only 99.999% sure that this is portable,
5783 and since the MinGW bug is fixed in a different way.
5784 * lib/autotest/general.m4 (AT_INIT): Likewise.
5786 2006-04-16 Stepan Kasal <kasal@ucw.cz>
5788 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Handle --recheck
5789 before opening config.log, to avoid hitting a bug on MinGW.
5791 2006-04-14 Paul Eggert <eggert@cs.ucla.edu>
5793 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Close
5794 AS_MESSAGE_LOG_FD before reopening it onto the log file.
5795 This works around a MinGW bug reported by Eric Paire.
5796 Make sure that all writes to the log file append to it,
5797 rather than possibly losing data.
5798 * lib/autotest/general.m4 (AT_INIT): Likewise.
5800 2006-04-14 Stepan Kasal <kasal@ucw.cz>
5802 * lib/Autom4te/FileUtils.pm (find_file): Fix a typo in the
5803 description.
5805 2006-04-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5807 * NEWS: Update.
5809 * configure.ac (AC_INIT): Bump to 2.59d.
5811 2006-04-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5813 Version 2.59c.
5815 * Makefile.maint (news-date-check): Do not require a leading `*'
5816 before the release date in NEWS.
5818 2006-04-12 Stepan Kasal <kasal@ucw.cz>
5819 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5821 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If the templates for
5822 the instantiated file do not contain the string 'datarootdir'
5823 but contain @datadir@, @docdir@, @infodir@, @localedir@, or
5824 @mandir@, replace the reference '${datarootdir}' by the value.
5825 * tests/torture.at (datarootdir workaround): New test.
5826 * NEWS: Advertise this temporary fixup.
5827 Based on a patch by Bruno Haible, reported and analyzed by
5828 Paul Eggert and Noah Misch.
5830 2006-04-12 Eric Blake <ebb9@byu.net>
5832 * tests/autotest.at (Debugging a failed test): Fix comment.
5834 2006-04-12 Stepan Kasal <kasal@ucw.cz>
5836 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): Simplify the summary of
5837 all the changes since 2006-04-07.
5839 2006-04-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5841 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): If `ln -s file1 file2'
5842 succeeded, but `ln -s file dir' failed, take care to remove the
5843 leftover target before the next test, to prevent its spurious
5844 failure; also make sure `ln file dir' works before selecting it.
5845 Thanks to Keith Marshall for pointing this out.
5846 * THANKS: Update.
5848 * lib/autotest/general.m4 (AT_INIT): Store quoted variable
5849 assignments in `at_debug_args', so that we put them correctly
5850 in the `run' script.
5851 * tests/autotest.at (Debugging a failed test): Unmark XFAIL.
5852 Reported by Eric Blake.
5854 2006-04-11 Eric Blake <ebb9@byu.net>
5856 * tests/autotest.at (AT_CHECK_AT): Add new argument, to allow
5857 top-level tests after micro-suite has been run. Used in...
5858 (Debugging a successful test, Debugging script and environment),
5859 (Debugging a failed test): ...these new tests. The first of these
5860 is fixed by...
5861 * lib/autotest/general.m4 (_AT_CREATE_DEBUGGING_SCRIPT): New
5862 macro, split out from...
5863 (AT_INIT): ...here, so that using -d also generates a run script.
5864 Document that -d inhibits top-level logging.
5865 * doc/autoconf.texi (testsuite Invocation): Document that -d only
5866 inhibits top-level logging; debug scripts are created.
5868 * lib/autotest/general.m4 (_AT_CHECK): Avoid syntax error on empty
5869 check.
5870 * tests/autotest.at (Empty test, Empty check): New test to check it.
5872 * lib/autoconf/c.m4 (AC_C_CONST, AC_C_VOLATILE): Avoid warnings
5873 from gcc.
5875 2006-04-10 Stepan Kasal <kasal@ucw.cz>
5877 * tests/mktests.sh: Use "trap '' 0", not "trap 0". Do not touch
5878 the files if a problem appears. Make the empty *.at files
5879 read-only, too. Proposed by Ralf Wildenhues.
5881 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5883 * config/Makefile.am: Add comment to force updated Makefile.in.
5885 * lib/freeze.mk: Fix typo in comment. Unlike the last, white
5886 space only patch to this file, this patch causes the Makefile.in
5887 files that include freeze.mk to be updated, and thus have a
5888 newer time stamp again, which in turn makes a pristine CVS
5889 checkout have correct time stamps.
5891 * Makefile.maint (cvs-sv): New macro, to be used..
5892 (config.guess-url_prefix, config.sub-url_prefix)
5893 (texinfo.tex-url_prefix, standards.texi-url_prefix): ..here;
5894 point to CVS text checkout of Gnulib files.
5895 (copyright-check): Bump current year.
5896 (announcement): Do not hard-wire `./announce-gen'.
5897 (cvs-update): Propagate failures of `cvs' and `move-if-change'
5898 correctly.
5899 * Makefile.cfg (executable-update): Use `chmod a+x' instead of
5900 `chmod +x'.
5901 (wget_files): Update config.guess, config.sub, texinfo.tex by
5902 `wget-update', now that their URLs work again.
5904 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
5906 * doc/autoconf.texi (Particular Types): Don't use AC_CHECK_TYPE.
5907 Problem noted by Paul D. Smith.
5909 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5911 * doc/autoconf.texi: Remove unused words from word list.
5912 * .x-sc_prohibit_atoi_atof, .x-sc_space_tab, .x-sc_sun_os_names,
5913 .x-sc_trailing_space: New files.
5915 * doc/standards.texi: Sync from gnulib.
5917 * NEWS, doc/autoconf.texi (AC_LIBOBJ vs LIBOBJS): Mark
5918 `LIBOBJDIR' as experimental.
5920 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): MSYS `ln -s' fails
5921 with a target directory; it's internally implemented as `cp'
5922 anyway, but since Autoconf advertises the possibility to use
5923 a target directory when LN_S is `ln -s', we need to find out.
5924 Reported by Rolf Ebert <rolf.ebert.gcc@gmx.de> against MSYS,
5925 analyzed by Keith Marshall <keith.marshall@total.com>.
5927 * THANKS: Update.
5929 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
5931 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Just output
5932 confdefs.h as-is. In general, if it has backslash-newline or the
5933 like, then it doesn't work either to sort or to remove empty
5934 lines.
5936 2006-04-09 Stepan Kasal <kasal@ucw.cz>
5938 * tests/Makefile.am (AUTOCONF_FILES): Fix typo in the comment.
5940 2006-04-09 Alexandre Duret-Lutz <adl@gnu.org>
5942 * lib/autom4te.in (Automake-preselections): Preselect
5943 _AM_SUBST_NOTMAKE.
5945 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>
5947 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Use '\'' for an
5948 apostrophe within a single-quoted string, as this is the usual
5949 tradition and is easier to read than '"'"'. Don't rely on the
5950 shell treating "$/" like '$/'. Use a more-consistent indenting
5951 style for the trap.
5953 2006-04-09 Eric Blake <ebb9@byu.net>
5955 * tests/autotest.at (Backquote command substitution),
5956 (Multiline backquote command substitution): Remove mistaken
5957 AT_NO_CMDSUBST from the 2006-03-14 patch, which was meant to be
5958 applied...
5959 (Parenthetical command substitution, Multiline parenthetical
5960 command substitution): here.
5962 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>
5964 Import macros from gnulib (often changing their name).
5966 * NEWS: AC_C_TYPE_LONG_DOUBLE is now obsolete.
5967 New macros AC_CHECK_DECLS_ONCE, AC_CHECK_FUNCS_ONCE,
5968 AC_CHECK_HEADERS_ONCE, AC_FUNC_STRTOLD, AC_HEADER_ASSERT,
5969 AC_STRUCT_DIRENT_D_INO, AC_STRUCT_DIRENT_D_TYPE,
5970 AC_TYPE_LONG_DOUBLE, AC_TYPE_LONG_DOUBLE_WIDER, AC_TYPE_INT8_T,
5971 AC_TYPE_INT16_T, AC_TYPE_INT32_T, AC_TYPE_INT64_T,
5972 AC_TYPE_INTMAX_T, AC_TYPE_INTPTR_T, AC_TYPE_LONG_LONG_INT,
5973 AC_TYPE_UINT8_T, AC_TYPE_UINT16_T, AC_TYPE_UINT32_T,
5974 AC_TYPE_UINT64_T, AC_TYPE_UINTMAX_T, AC_TYPE_UINTPTR_T,
5975 AC_TYPE_UNSIGNED_LONG_LONG_INT, AC_USE_SYSTEM_EXTENSIONS.
5976 The manual mentions Gnulib more prominently.
5977 * doc/autoconf.texi (Gnulib): New node.
5978 (Pointers): Add Gnulib URL.
5979 (Particular Functions): Alphabetize. Add AC_FUNC_STRTOLD.
5980 (Generic Functions): Add AC_CHECK_FUNCS_ONCE. Refer to new
5981 Gnulib section.
5982 (Particular Headers): Add AC_HEADER_ASSERT. For stdbool.h,
5983 suggest a #define rather than a typedef for _Bool, and mention
5984 Gnulib rather than trying to substitute stdbool code.
5985 (Generic Headers): Add AC_CHECK_HEADERS_ONCE.
5986 (Generic Declarations): Add AC_CHECK_DECLS_ONCE.
5987 (Particular Structures): Add AC_STRUCT_DIRENT_D_INO,
5988 AC_STRUCT_DIRENT_D_TYPE.
5989 (Particular Types): Mention stdint.h and inttypes.h as standard
5990 headers too.
5991 Add AC_TYPE_INT8_T, AC_TYPE_INT16_T, AC_TYPE_INT32_T, AC_TYPE_INT64_T,
5992 AC_TYPE_INTMAX_T, AC_TYPE_INTPTR_T, AC_TYPE_LONG_DOUBLE,
5993 AC_TYPE_LONG_DOUBLE_WIDER, AC_TYPE_LONG_LONG_INT, AC_TYPE_UINT8_T,
5994 AC_TYPE_UINT16_T, AC_TYPE_UINT32_T, AC_TYPE_UINT64_T,
5995 AC_TYPE_UINTMAX_T, AC_TYPE_UINTPTR_T, AC_TYPE_UNSIGNED_LONG_LONG_INT.
5996 (C Compiler): Move AC_C_LONG_DOUBLE to ...
5997 (Obsolete Macros): here. Under AC_LONG_DOUBLE, mention
5998 AC_TYPE_LONG_DOUBLE or AC_TYPE_LONG_DOUBLE_WIDER instead.
5999 (Posix Variants): Add AC_USE_SYSTEM_EXTENSIONS.
6000 (Coding Style). Don't mention m4_expand_once.
6001 * lib/autoconf/c.m4 (AC_C_LONG_DOUBLE): Implement via
6002 AC_TYPE_LONG_DOUBLE_WIDER. Now obsolete.
6003 * lib/autoconf/functions.m4 (_AH_CHECK_FUNCS): New macro.
6004 (AC_CHECK_FUNCS): Use it.
6005 (AC_CHECK_FUNCS_ONCE, AC_FUNC_STRTOLD): New macros.
6006 (AC_FUNC_WAIT3): "the Open Group standards" -> "POSIX".
6007 * lib/autoconf/general.m4 (AC_CHECK_DECLS_ONCE): New macro.
6008 * lib/autoconf/headers.m4 (AC_CHECK_HEADERS_ONCE): New macro.

6040 _AS_DETECT_BETTER_SHELL:
6042 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Do not optimize; do not
6043 skip nonexistent directories.
6044 (_AS_DETECT_BETTER_SHELL): The optimization is moved here--try
6045 only shell candidates which exist.
6046 (AS_UNAME): No need to give three parameters to _AS_PATH_WALK.
6047 * lib/autotest/general.m4 (AT_INIT): No need to give three
6048 parameters to _AS_PATH_WALK.
6050 2006-04-07 Stepan Kasal <kasal@ucw.cz>,
6051 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6053 * bin/autoupdate.in (handle_autoconf_patches): Change the way we
6054 distinguish m4sugar macros.
6055 * tests/tools.at (autoupdating with aclocal and m4_include):
6056 New test. Bug reported by Gary V. Vaughan <gary@gnu.org>,
6057 test case by Noah Misch <noah@cs.caltech.edu>.
6059 2006-04-07 Stepan Kasal <kasal@ucw.cz>
6061 Revert my change from 2006-03-17, in other words:
6062 * lib/m4sugar/m4sh.m4 (AS_BOURNE_COMPATIBLE): Insert BIN_SH=xpg4
6063 and DUALCASE=1.
6064 (AS_SHELL_SANITIZE): Remove DUALCASE=1.
6065 * doc/autoconf.texi (Special Shell Variables) <BIN_SH>: Say that
6066 it is set.
6068 2006-04-07 Eric Blake <ebb9@byu.net>
6070 * doc/autoconf.texi (Programming in M4sh): Document that
6071 AS_MKDIR_P exits the script on failure.
6072 * lib/autotest/general.m4: Remove redundant AS_ERROR.
6074 2006-04-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6076 * config/elisp-comp, config/install-sh, config/mdate-sh,
6077 config/missing, config/mkinstalldirs: Sync from Automake.
6079 * lib/Autom4te/FileUtils.pm, lib/Autom4te/Struct.pm: Sync
6080 from Automake.
6082 * doc/make-stds.texi: Sync from gnulib.
6084 2006-04-06 Eric Blake <ebb9@byu.net>
6086 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_O): Inside cache
6087 check, s/ac_exeext/ac_cv_exeext/. Fixes regression introduced

6091 Eric Blake <ebb9@byu.net>,
6092 Paul Eggert <eggert@cs.ucla.edu>,
6093 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6095 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): Fix the detection of
6096 whether `set' quotes correctly: redirect stderr of the tested
6097 `set', and use a subshell, for Ultrix; use `sed' instead of
6098 `grep' for zsh `set' which may write binary output; match only
6099 at the beginning of a line, to avoid false positives.
6100 In order to avoid false positives by unrelated variables with
6101 multiline content, put the dump algorithm in a subshell and
6102 unset all variables containing newlines (except some which are
6103 special to the shell). Warn about cache variables that are
6104 unset.
6106 2006-04-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6108 * config/config.guess, config/config.sub, config/texinfo.tex:

6116 (AC_ARG_VAR): Do test this now.
6117 (AC_SEARCH_LIBS, AC_REPLACE_FUNCS): Need an argument.
6118 (AC_LINKER_OPTION): Remove (renamed to _AC_LINKER_OPTION).
6119 (AC_LIST_MEMBER_OF): Likewise (renamed to _AC_LIST_MEMBER_IF).
6120 (AC_LINK_FILES): Obsoleted since (and thus AU_DEFUN'ed).
6122 * doc/autoconf.texi (Shell Substitutions): Mention the MSYS
6123 shell issue with double-quoted command substitutions of native
6124 commands.

6143 2006-04-06 Stepan Kasal <kasal@ucw.cz>
6145 * tests/Makefile.am (maintainer-check-posix):
6146 s/POSIXLY_CORRECTLY/POSIXLY_CORRECT/
6148 * lib/autoconf/status.m4 (_AC_CONFIG_FOOS): Append TAGS to
6149 ac_config_<foo>s again, sometimes normalized, sometimes not.
6150 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_LINKS):
6151 (AC_CONFIG_COMMANDS): Do not do so here.
6152 (_AC_CONFIG_REGISTER_DEST): Double quote the tags in macros _AC_LIST_TAGS
6153 and_AC_LIST_TAG_COMMANDS; fixes another regression introduced by the
6154 2005-07-25 rewrite. Noticed by Noah Misch.
6156 * lib/autoconf/general.m4 (AC_PRESERVE_HELP_ORDER): Do not define
6157 _AC_PRESERVE_HELP_ORDER, ...
6158 (AC_ARG_ENABLE, AC_ARG_WITH): ... use AC_PROVIDE_IFELSE insetad.
6160 * lib/autoconf/general.m4 (AC_ARG_VAR): Do not use m4_divert_once
6161 inside m4_expand_once; it is redundant.
6163 * lib/autoconf/general.m4 (_AC_INIT_HELP): Remove the broken support
6164 for --help from Cygnus `configure.'
6166 2006-04-06 Paul Eggert <eggert@cs.ucla.edu>

6176 2006-04-05 Howard Chu <hyc@highlandsun.com> (trivial change)
6177 Noah Misch <noah@cs.caltech.edu>
6179 * lib/autoconf/general.m4 (AC_PRESERVE_HELP_ORDER): New macro.
6180 (AC_ARG_ENABLE, AC_ARG_WITH): Adjust.
6181 * doc/autoconf.texi (Help Formatting): New node.
6182 * NEWS: Announce AC_PRESERVE_HELP_ORDER.
6184 2006-04-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6186 * TODO, config/Makefile.am, lib/freeze.mk, lib/autoconf/c.m4,
6187 lib/autoconf/specific.m4, lib/autoconf/status.m4,
6188 lib/autoconf/types.m4, lib/autotest/general.m4,
6189 tests/mktests.sh, tests/torture.at: White space cleanup:

6192 * NEWS, TODO, bin/autoreconf.in: `filesystem' -> `file system'.
6194 * doc/autoconf.texi (Shell Substitutions): Document `^' vs. `|'.
6196 2006-04-05 Eric Blake <ebb9@byu.net>
6198 * lib/autotest/general.m4 (AT_INIT): Prep AT_*_all, so that an
6199 empty test suite works.
6200 * tests/autotest.at (Empty test suite): Remove xfail.
6202 2006-04-05 Noah Misch <noah@cs.caltech.edu>

6205 TAGS to ac_config_<foo>s.
6206 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_LINKS): Do so here.
6207 (AC_CONFIG_COMMANDS): Append NAME to ac_config_commands without
6208 normalizing it, consistent it with previous releases.
6209 * tests/torture.at (Macro calls in AC_CONFIG_COMMANDS tags): New test.
6211 2006-04-05 Paul Eggert <eggert@cs.ucla.edu>
6213 * lib/m4sugar/m4sh.m4 (AS_BASENAME_EXPR, AS_DIRNAME_EXPR):
6214 Use simplified args that Eric Blake originally suggested.
6216 2006-04-04 Paul Eggert <eggert@cs.ucla.edu>
6218 * tests/mktests.sh: Don't use 'cat'; just read the files directly.
6219 Prefer 'sort -u' to 'sort | uniq'. Filter data before sorting it.
6220 Use 'comm' rather than N instances of grep; this also fixes a bug
6221 whereby substrings were incorrectly matched, causing us to not
6222 generate tests for AC_F77_NAME_MANGLING and AC_FUNC_LSTAT.
6223 (exclude_list): Exclude empty macros.
6224 (ac_exclude_list): Exclude AC_INCLUDES_DEFAULT.
6226 Use awk rather than grep -E or egrep, to avoid
6227 portability problems with regular expressions containing newlines.

6229 Switch from grep to awk syntax.
6230 (ac_exclude_script): Renamed from ac_exclude_egrep.
6231 (au_exclude_script): Renamed from au_exclude_egrep.
6233 2006-04-04 Noah Misch <noah@cs.caltech.edu>
6235 * lib/autoconf/general.m4 (_AC_INIT_HELP): Only `configure.in' evidences
6236 a subdirectory subject to Cygnus `configure'.
6237 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Likewise.
6239 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): Omit the bug
6240 report request when we have no AC_PACKAGE_BUGREPORT.
6242 2006-04-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6244 * THANKS: Update.

6247 generated files.
6249 * lib/autoconf/c.m4 (AC_C_INLINE): Do not skip cleanup code.
6250 (AC_C_RESTRICT): Likewise. Furthermore, add a function with a
6251 typedef'ed restricted pointer, to catch a compiler bug on
6252 HP-UX 11.x, and fix warnings so it passes with -Werror.
6253 (_AC_PROG_CC_C99): Likewise.
6254 Reported by Albert Chin <china@thewrittenword.com>.
6255 * tests/mktests.sh: Do not skip AC_C_INLINE, AC_C_RESTRICT.

6270 * THANKS: Add myself.
6272 2006-04-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6274 * lib/autotest/general.m4 (AT_INIT): Add `at_testdir' to pointer
6275 to log, point to testsuite output tree.
6277 2006-04-02 Paul Eggert <eggert@cs.ucla.edu>
6279 * NEWS: AC_PROG_CC and AC_PROG_CXX no longer declare 'exit'.

6284 Remove; all uses removed.
6285 (AC_LANG_INT_SAVE(C), AC_C_BIGENDIAN):

6305 Clean up _AC_COMPILER_EXEEXT* macros.
6307 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't try to
6308 detect exeext, it will be done by _AC_COMPILER_EXEEXT_O; just set
6309 ac_file to the name of the default output file and call
6310 _AC_COMPILER_EXEEXT_WORKS. Move the definition of ac_files and the
6311 initial `rm' of the candidate files...
6312 (_AC_COMPILER_EXEEXT): ... here and simplify them. Moreover, use
6313 the same list in subsequent `rm' calls, and for the temporary
6314 redefinition of ac_clean_files; call _AC_COMPILER_OBJEXT at the end,
6315 and don't call the other _AC_COMPILER_EXEEXT_* macros directly, use...
6316 (_AC_COMPILER_EXEEXT_TESTS): ... this new macro.
6317 (_AC_COMPILER_EXEEXT_O): Don't export ac_cv_exeext, it's not needed (or
6318 no longer needed) by libtool. Make it a cache check.
6319 (_AC_COMPILER_EXEEXT_CROSS): Remove the comment, it was obviously
6320 copied here by mistake.
6321 (AC_NO_EXECUTABLES): Redefine _AC_COMPILER_EXEEXT_TESTS, not
6322 _AC_COMPILER_EXEEXT.
6323 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX, AC_PROG_OBJC): Do not call
6324 _AC_COMPILER_OBJEXT directly.

6355 * lib/autoconf/general.m4 (_AC_INIT_VERSION): Emit script name and
6356 Autoconf version number despite a zero- or one-argument AC_INIT.
6358 * bin/autoreconf.in (parse_args): Multiple -v send --verbose to
6359 subordinate tools.
6360 * lib/Autom4te/General.pm (getopt): Make -v and -d incremental.
6361 * doc/autoconf.texi (autoreconf Invocation): Document it.
6363 * doc/autoconf.texi: Use `Cygwin', `MinGW', and `license' consistently.
6364 Append LocalWords so ispell-buffer passes cleanly. Spelling fixes.

6370 rm failed to remove it.
6372 2006-04-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6374 * bin/autoupdate.in: Redefine m4_location so that warnings print
6375 the correct lines of the input file by subtracting..
6376 (_au__first_line): ..this new definition.
6378 * lib/autoconf/general.m4 (AC_COMPILE_CHECK): Prefer
6379 AC_MSG_CHECKING over obsolete AC_CHECKING in autoupdated code.
6380 Remove stray newline in output.
6381 (AC_FOREACH): AU_DEFUN this as literal for autoupdate, and also
6382 AC_DEFUN this for autoconf, including the obsoletion diagnose.
6383 Fixes autoupdating of code where the replacement output contains
6384 m4sugar macros.
6385 * lib/autoconf/lang.m4 (AC_LANG_SAVE): Likewise.
6386 * tests/mktests.sh (ac_exclude_list): Add AC_FOREACH.

6388 * tests/tools.at: Several new tests for all of this.
6389 * doc/autoconf.texi (Obsoleting Macros): Give a hint about the
6390 hairy details.
6391 The AC_LANG_SAVE issue was reported against Libtool by
6392 Dalibor Topic <robilad@kaffe.org>, and against Autoconf 2.57 by
6393 Kristian Kvilekval <kris@cs.ucsb.edu>.
6395 2006-04-01 Stepan Kasal <kasal@ucw.cz>
6397 * bin/autoupdate.in: Handle m4 builtins and m4sugar macros together--
6398 switch all of them on and of when necessary. Fixes the bug when
6399 m4sugar macros (e.g., m4_define) were expanded after the first
6400 automatic update (e.g., after AC_PREREQ or AC_INIT).
6402 2006-03-31 Paul Eggert <eggert@cs.ucla.edu>

6420 in texinfo files outside of verbatim environments.
6421 (syntax-check-rules): Update.

6424 2006-03-30 Chris Pickett <cpicke@cs.mcgill.ca> (tiny change)
6426 * doc/autoconf.texi (autoreconf Invocation): Mention that -I for
6427 aclocal cannot be given on the command line.
6429 2006-03-29 Paul Eggert <eggert@cs.ucla.edu>
6431 * doc/autoconf.texi (Programming in M4sh): Mention AS_BASENAME.
6432 Give an example for AS_DIRNAME instead of referring to Posix..
6433 (File System Conventions): Put discussion of // versus / here, and
6434 modernize it a bit.
6435 (Limitations of Usual Tools): Add basename. Remove verbiage
6436 after dirname, since it got moved to the above sections.
6437 All this was inspired by a patch proposed earlier by Eric Blake.
6439 2006-03-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6441 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Quote

6445 `$0', $as_me.
6447 2006-03-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6449 * bin/autoscan.in: The value of find_configure_ac should be
6450 checked for existence, so we don't barf over a nonexisting
6451 configure.ac. Reported by Laurence Darby <ldarby@tuffmail.com>.
6453 2006-03-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

7039 Factor functionality to..
7040 (_AC_CHECK_PROG, _AC_PATH_PROG): these new macros, but only
7041 `AC_SUBST($1)' in the public version.
7042 (AC_CHECK_TOOL, AC_PATH_TOOL, AC_PATH_TARGET_TOOL)
7043 (AC_CHECK_TARGET_TOOL): Use internal versions for ac_ct_* and
7044 ac_pt_* variables.

7066 2005-10-24 Stepan Kasal <kasal@ucw.cz>
7068 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Use conftst2.o instead of
7069 conftest.o, to see whether the compiler really obeys; rm the object
7070 file before and after the test and register it with ac_clean_files.
7071 * lib/autoconf/fortran.m4 (_AC_PROG_FC_C_O): Likewise.
7073 2005-10-21 Stepan Kasal <kasal@ucw.cz>

7091 2005-10-19 Paul Eggert <eggert@cs.ucla.edu>
7093 * doc/autoconf.texi (Generating Sources): AC_LANG_PROGRAMS ->
7094 AC_LANG_PROGRAM, fixing a typo. Don't give details about
7095 the inner workings of AC_LANG_FUNC_LINK_TRY.
7096 * lib/autoconf/c.m4 (AC_LANG_CALL(C)): Reformat to match
7097 AC_LANG_FUNC_LINK_TRY. This involves returning the value returned
7098 by the function rather than ignoring it.
7099 (AC_LANG_FUNC_LINK_TRY(C)): Call the function rather than simply
7100 comparing its address. Intel's interprocedural optimization was
7101 outsmarting the old heuristic. Problem reported by
7102 Mikulas Patocka.
7104 2005-10-19 Stepan Kasal <kasal@ucw.cz>
7106 * lib/autoconf/general.m4 (AC_SUBST): Remove an obsolete comment.

7110 * lib/m4sugar/m4sugar.m4 (_m4_map): New macro.
7111 (m4_map, m4_map_sep): Use it. Handle the empty list correctly.
7113 2005-10-04 Stepan Kasal <kasal@ucw.cz>
7115 * lib/autotest/general.m4 (AT_INIT): Really make the subtree writable
7116 before removing it (chmod -R u+rwx); there are three instances of this.
7118 2005-10-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7119 Stepan Kasal <kasal@ucw.cz>
7121 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Balance parentheses.
7122 * lib/autotest/general.m4 (AT_INIT): If the test dir already exists,
7123 make its content writable before removing it. Remove an errorneous
7124 comment from the end, where the logs of the failed tests are copied
7125 to the main log file.
7127 2005-09-27 Stepan Kasal <kasal@ucw.cz>
7129 * tests/semantics.at (AC_C_BIGENDIAN): Pass --force to autoheader,
7130 in case the computer is too quick. Double quote the configure.ac
7131 snippets.
7133 * tests/local.at (AT_CHECK_AUTOCONF): Always pass --force to prevent
7134 problems if the testsuite were running too fast.
7136 2005-09-18 Paul Eggert <eggert@cs.ucla.edu>
7138 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Look for X11/Xlib.h
7139 and XrmInitialize rather than X11/Intrinsic.h and XtMalloc
7140 (which belong to Xt, not X itself). See Debian bug 327655.
7141 * NEWS: Mention this.
7143 2005-09-07 Stepan Kasal <kasal@ucw.cz>
7145 * lib/autoconf/c.m4 (AC_LANG_SOURCE(C)): Remove an incorrect comment.
7147 2005-09-06 Paul Eggert <eggert@cs.ucla.edu>
7149 * config/move-if-change: Don't output "$2 is unchanged";
7150 suggested by Ben Elliston. Handle weird characters correctly.
7152 2005-09-06 Stepan Kasal <kasal@ucw.cz>
7154 * lib/autoconf/libs.m4 (AC_SEARCH_LIBS): Merge the two AC_LINK_IFELSE
7155 calls, so that the final expansion of this macro is shorter.
7156 Create the conftest.$ac_ext outside the `for' loop, to speed the run.
7157 Do not use `break' in the argument to AC_LINK_IFELSE, it would skip
7158 the cleanup there. Use AS_VAR_* macros, to be more general.
7159 * tests/semantics.at (AC_SEARCH_LIBS): Check for the cleanup.
7161 * lib/autoconf/general.m4: Use AS_IF where appropriate.
7163 * lib/m4sugar/m4sh.m4 (AS_IF): Use m4_default.
7165 2005-09-01 Stepan Kasal <kasal@ucw.cz>
7167 * doc/autoconf.texi (Configuration Headers): Add an index entry
7168 for AH_HEADER.
7170 2005-08-26 Pavel Roskin <proski@gnu.org>
7172 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): Use shell variable
7173 XMKMF to locate xmkmf. Make XMKMF precious. Export CC when
7174 running xmkmf.
7176 2005-08-26 Paul Eggert <eggert@cs.ucla.edu>
7178 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE):
7179 The previous patch didn't work, so try a better one.
7181 2005-08-26 Stepan Kasal <kasal@ucw.cz>
7183 * doc/autoconf.texi (Programming in M4sh) <AS_TR_CPP>: Fix m4 quoting
7184 in the example. Reported by Bruno Haible.
7185 <AS_TR_SH>: Likewise. Also modify the example to be more convincing:
7186 "if $undefined_var;" succeeds with my shell.
7188 * lib/autoconf/general.m4 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST,
7189 AC_CANONICAL_TARGET): Define by AC_DEFUN, no need to use AC_DEFUN_ONCE;
7190 but change the m4_divert_text to m4_divert_once.
7192 2005-08-25 Paul Eggert <eggert@cs.ucla.edu>
7194 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE):
7195 Work around bug in Solaris /usr/xpg4/bin/awk.
7196 The bug is present in at least Solaris 8 through 10.
7198 2005-08-24 Stepan Kasal <kasal@ucw.cz>
7200 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Simplify; rejecting
7201 some evil values and relying on the fact that $* concatenates the
7202 parameters by the first character from IFS.
7204 2005-08-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
7205 Stepan Kasal <kasal@ucw.cz>
7207 * lib/autoconf/status.m4 (_AC_CONFIG_REGISTER_DEST): When the
7208 first header appears, define AH_HEADER.
7209 * doc/autoconf.texi (Configuration Headers): Document AH_HEADER.
7210 Update limitations about when to call AC_CONFIG_HEADERS.
7211 (Configuration Commands): Document that AC_CONFIG_COMMANDS_PRE
7212 parameter can call AC_SUBST, AC_DEFINE, or AC_CONFIG_FOOS; explain
7213 that AC_CONFIG_COMMANDS_PRE and AC_CONFIG_COMMANDS_POST are not
7214 ``Configuration Actions''; fix their index entries.
7216 * lib/autotest/general.m4 (AT_INIT): Process multiple keywords
7217 options correctly. Process N-M as M-N if M is smaller than N.
7218 Process ranges correctly so that N-N will run only N.
7219 Sort and uniquify the tests that will be run. If there is more
7220 than one test, reinsert the banners for the tests.
7221 * tests/autotest.at (Keywords): Unmark XFAIL.
7223 2005-08-23 Stepan Kasal <kasal@ucw.cz>
7225 * lib/autoconf/general.m4 (_AC_DEFINE_Q): Strip the parameter list
7226 before passing the macro name to AH_TEMPLATE.
7228 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): config.status
7229 now opens log after option processing; in particular, --version
7230 and --help do not touch config.log.
7232 * Makefile.maint: Revert the change from 2005-08-12.
7234 2005-08-22 Stepan Kasal <kasal@ucw.cz>
7236 * lib/autoconf/general.m4 (AC_ARG_ENABLE, AC_ARG_WITH): Factor out
7237 common code to...
7238 (_AC_ENABLE_IF, _AC_ENABLE_IF_ACTION): ... these new macros.
7240 2005-08-21 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7242 * doc/autoconf.texi (Using Autotest, testsuite Scripts)
7243 (Autotest Logs, Writing testsuite.at, testsuite Invocation):
7244 Language cleanup.
7246 * doc/autoconf.texi (Defining Symbols, Changed Results):
7247 Prepend to LIBS, not append, in examples.
7249 2005-08-16 Stepan Kasal <kasal@ucw.cz>
7251 When building in place, set srcdir="."; suggested by Tim Van Holder.
7253 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Do this; to recognize
7254 build in place, we need ac_pwd, and thus have to AC_REQUIRE ...
7255 (_AC_INIT_DIRCHECK): ... this macro and AC_DEFUN both of them.
7256 * lib/autoconf/status.m4 (_AC_SRCDIRS): Fix a comment: srcdir="."
7257 does not mean "no --srcdir option".
7259 2005-08-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7261 * tests/autoscan.at (autoscan): New file.
7262 * tests/suite.at: Use it.
7263 * tests/Makefile.am (TESTSUITE_HAND_AT): Add it.
7264 Reported against Libtool by Gideon Go <gideon.go@gmail.com>.
7266 * tests/autotest.at (Keywords): Test keywords combinations.
7268 2005-08-12 Stepan Kasal <kasal@ucw.cz>
7270 * Makefile.maint (GZIP_ENV): When checking the help text of gzip,
7271 add "2>&1"; gzip 1.2.4 prints help on stderr.
7273 2005-07-27 Stepan Kasal <kasal@ucw.cz>
7275 * lib/autotest/general.m4 (_AT_DECIDE_TRACEABLE): The symbol at_reason
7276 was pushdef'ed twice while popped only once. Push it only once.
7277 (_AT_CHECK): Cosmetic changes to the "case $at_status" command.
7279 2005-07-26 Stepan Kasal <kasal@ucw.cz>
7281 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): The message is now
7282 prefixed by mere "===", not "configure: === ".
7284 2005-07-25 Paul Eggert <eggert@cs.ucla.edu>
7286 * Makefile.maint: Update from Bison.
7288 * lib/m4sugar/m4sugar.m4 (m4_strip): Comment fix---change tab to
7289 "<tab>" in comment, so that the point is understandable.
7291 2005-07-25 Stepan Kasal <kasal@ucw.cz>
7293 Rewrite substantial part of lib/autoconf/status.m4.
7294 The main change is that CONFIG_FILES, CONFIG_HEADERS, CONFIG_LINKS,
7295 and CONFIG_COMMANDS are not processed in four separate loops.
7296 Instead, there is one main loop. This alows that the common code
7297 is expanded only once, thus config.status (and configure) is smaller.
7299 The registration mechnism in AC_CONFIG_FILES and cousins also changed;
7300 the AC_LIST_FILES and cousins macros are no longer used.
7302 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES, _AC_OUTPUT_HEADERS,
7303 _AC_OUTPUT_LINKS, _AC_OUTPUT_COMMANDS): Renamed to ...
7304 (_AC_OUTPUT_FILE, _AC_OUTPUT_HEADER, _AC_OUTPUT_LINK,
7305 _AC_OUTPUT_COMMAND): ..., respectively. These macros no longer
7306 contain the initialization, nor the for loop, nor the associated
7307 commands; all these go to ...
7308 (_AC_OUTPUT_MAIN_LOOP): ... this new macro, called from
7309 _AC_OUTPUT_CONFIG_STATUS.
7310 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST, _AC_CONFIG_SPLIT_FILE_IN):
7311 Nuked; the code was merged into _AC_OUTPUT_MAIN_LOOP.
7312 (_AC_OUTPUT_FILE): The creation of the sed script ...
7313 (AC_OUTPUT): ... and the setup of ac_vpsub goes to ...
7314 (_AC_OUTPUT_FILES_PREPARE): ... a new macro, also called from
7315 _AC_OUTPUT_MAIN_LOOP.
7316 (_AC_CONFIG_FILES, _AC_CONFIG_HEADERS, _AC_CONFIG_LINKS,
7317 _AC_CONFIG_COMMANDS): Use ...
7318 (_AC_CONFIG_FOOS): ... this new macro, which uses these ...
7319 (_AC_CONFIG_REGISTER, _AC_CONFIG_REGISTER_DEST): ... new macros.
7320 (_AC_CONFIG_FILE, _AC_CONFIG_HEADER, _AC_CONFIG_LINK,
7321 _AC_CONFIG_COMMAND, _AC_CONFIG_DEPENDENCIES): No longer needed.
7322 (_AC_CONFIG_DEPENDENCY): Update, it uses these ...
7323 (_AC_CONFIG_DEPENDENCY_DEFAULT, _AC_FILE_DEPENDENCY_TRACE_COLON):
7324 ... new macros.
7325 (_AC_CONFIG_UNIQUE): Update.
7326 (AC_LIST_FILES, AC_LIST_HEADERS, AC_LIST_LINKS, AC_LIST_COMMANDS):
7327 Replaced by this ...
7328 (_AC_LIST_TAGS): ... new common macro.
7329 (AC_LIST_FILE_COMMANDS, AC_LIST_HEADER_COMMANDS, AC_LIST_LINK_COMMANDS,
7330 AC_LIST_COMMAND_COMMANDS): Replaced by this ...
7331 (_AC_LIST_TAG_COMMANDS): ... new common macro.
7332 (_AC_CONFIG_COMMANDS_INIT): Moved top to the `registration' section;
7333 this didn't belong to the `config commands' section.
7334 (_AC_OUTPUT_COMMANDS_INIT): Don't initialize, m4_ifdef is our friend.
7335 (AC_CONFIG_COMMANDS_PRE, AC_OUTPUT_COMMANDS_PRE,
7336 AC_CONFIG_COMMANDS_POST): Moved to a new section, these didn't belong
7337 to the `config commands' section either.
7338 (AC_CONFIG_SUBDIRS): Don't touch diversion DEFAULTS.
7339 (_AC_LIST_SUBDIRS): Don't initialize, m4_ifdef is our friend.
7341 ... and many changes to the comments nearby.
7343 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): At the end of the day,
7344 set ac_subdirs_all='_AC_LIST_SUBDIRS'.
7345 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
7346 AC_CONFIG_COMMANDS(command:input,...) is no longer allowed.
7347 (#define header templates): The comment at the top of the generated
7348 header now includes the name(s) of the source file(s).
7350 Several unrelated small changes:
7352 * lib/autoconf/general.m4 (AC_CACHE_VAL): Be didactic, quote the first
7353 parameter to AC_DIAGNOSE.
7354 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS): Likewise.
7355 (_AC_LINK_FILES_CNT): Don't AU_DEFUN this; it causes confusing messages
7356 with autoupdate; use m4_define_default inside AU_DEFUNed AC_LINK_FILES.
7357 (AC_OUTPUT): In the compatibility code, use m4_ifvaln, to be consistent
7358 with AU::AC_OUTPUT.
7359 (AU::AC_OUTPUT): Don't double-quote $2 and $3, the compatibility code
7360 in AC_OUTPUT doesn't double-quote it either.
7361 * tests/tools.at (autoupdate): AU::AC_OUTPUT no longer double-quotes the
7362 parameters.
7364 2005-07-10 Stepan Kasal <kasal@ucw.cz>
7366 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Document which
7367 versions of Portland Group compiler produce single- and double-quoted
7368 -cmdline argument. Reported by Steven G. Johnson <stevenj@fftw.org>
7369 and Ole Holm Nielsen <Ole.H.Nielsen@fysik.dtu.dk>.
7371 2005-07-07 Paul Eggert <eggert@cs.ucla.edu>
7373 * tests/local.at (AT_CONFIG_CMP): Ignore lines like "LIBS=''" too.
7374 This is a corrected version of yesterday's patch.

7383 (AC_CANONICAL_HOST, AC_CANONICAL_TARGET): Simplify.
7385 On 2005-02-24, an unintentional AC_SUBST([CC]) was introduced; this
7386 change eliminates it. Problem reported by Alexandre Duret-Lutz.
7387 * lib/autoconf/general.m4 (_AC_ARG_VAR_PRECIOUS): Move the AC_SUBST ...
7388 (AC_ARG_VAR): ... here.
7389 (_AC_INIT_PREPARE): Call AC_SUBST for build_alias, host_alias and
7390 target_alias.
7392 Keep a list of all precious variables and process them with one simple
7393 for loop, instead of expanding all commands, or, OTOH, complicated
7394 processing of output of "set".
7395 * lib/autoconf/general.m4 (_AC_ARG_VAR_PRECIOUS): Acumulate the
7396 variable names in new macro...

7399 a loop to assign all ac_env_* and ac_cv_env_* variables.
7400 (_AC_ARG_VAR_VALIDATE): Use shell variable ac_precious_vars, divert
7401 to INIT_PREPARE.
7402 (_AC_INIT_DEFAULTS): At the end, if _AC_PRECIOUS_VARS is set, assign
7403 its value to shell variable ac_precious_vars and call
7404 _AC_ARG_VAR_STORE and _AC_ARG_VAR_VALIDATE.

7446 * bin/autom4te.in ($m4): Catch usages like --nesting-limit=2048.

7451 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Use &, not |, in
7452 sed substitution command, so that we allow | in program prefixes
7453 and program suffixes. (& is a problem anyway; we're not fixing

7455 * lib/autoconf/status.m4 (AC_CONFIG_FILES): Likewise, for
7456 configure_input, top_builddir, srcdir, etc.
7457 * lib/autotest/general.m4 (AT_INIT): Likewise, for
7458 PATH_SEPARATOR in AUTOTEST_PATH.
7460 2005-07-02 Alexandre Duret-Lutz <adl@gnu.org>
7462 * lib/autoconf/general.m4 (AC_SITE_LOAD): Rewrite the

7468 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Remove the tests for

7491 document to output the default config_* lists to config.status.
7492 Don't recognize option --file, if the functionality is not there.
7493 Likewise for --header; moreover, recognize --he and --h as shortcuts
7494 for --help in that case.
7496 * lib/autoconf/status.m4: Fix the order of the "sections", so that it
7497 matches the order of execution. No code changed.

7519 instead of AC_SUBST; proposed by Alexandre Duret-Lutz.
7520 (AC_SUBST): Call it.
7521 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Call AC_SUBST_TRACE for
7522 the directory specific variables; but don't call it for configure_input.
7524 2005-06-28 Derek Price <derek@ximbiot.com>
7526 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: Reword recent
7527 addition.
7529 2005-06-23 Paul Eggert <eggert@cs.ucla.edu>

7532 directory have inherent problems with special characters like spaces,
7533 due to limitations in Make syntax. Problem reported by Alexandre
7534 Duret-Lutz.
7535 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Implement the above.

7548 from Justace Clutter.
7549 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Put name of invalid
7550 variable into diagnostic. Make the diagnostic an error, not a warning,
7551 because we really don't support spaces and suchlike in dir names.
7552 (_AC_INIT_SRCDIR): Allow special characters in $ac_unique_file.
7553 Don't worry about backslashes in srcdir; it can't happen now.

7580 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: Document that
7581 b, t, r, w commands require single space, while : cannot have any.
7582 (Special Shell Variables): Fix sed code this in the example.
7583 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Likewise; and fix a typo.
7584 * lib/autotest/general.m4 (AT_ARG_OPTION): Fix typo in the description.
7586 * lib/m4sugar/m4sugar.m4 (m4_split): If the parameter is empty,
7587 expand to the empty list. Don't use two pairs of m4_changequote,
7588 it's not necessary.

7596 * lib/m4sugar/m4sh.m4 (as_awk_strverscmp): Port to Solaris /bin/awk.
7597 * doc/autoconf.texi:
7598 Don't mention Solaris versions so much, if a
7599 problem is common to all extant versions of Solaris. Say "SunOS
7600 4" instead of "SunOS" for SunOS 4.
7601 (awk): Mention more of the limitations of traditional Awk.
7602 (cat): Don't talk about cat -v.
7604 2005-06-16 Paul Eggert <eggert@cs.ucla.edu>

7609 to be compatible with glibc strverscmp.
7610 * tests/m4sh.at (AS_VERSION_COMPARE): New test.
7612 * doc/autoconf.texi (Limitations of Usual Tools): Mention expr bug
7613 on Mac OS X 10.4 reported by Peter O'Gorman in:

7618 2005-06-10 Paul Eggert <eggert@cs.ucla.edu>
7620 * doc/autoconf.texi: "filesystem" -> "file system".
7621 "behaviour" -> "behavior".

7624 as per POSIX.
7625 * lib/m4sugar/m4sh.m4: Likewise.

7642 2005-06-08 Paul Eggert <eggert@cs.ucla.edu>
7644 * lib/autotest/general.m4 (AT_INIT): Don't accept Solaris 9's diff
7645 -u, since it outputs chatter if the input files are the same.
7646 Problem reported by Ralf Menzel.
7648 2005-06-08 Derek Price <derek@ximbiot.com>
7650 * lib/m4sugar/m4sugar.m4: Undefine include & sinclude rather than
7651 renaming them since they are about to be redefined anyhow.
7653 2005-06-08 Derek Price <derek@ximbiot.com>
7655 * doc/autoconf.texi (Redefined M4 Macros): Add index entries for most
7656 redefined M4 macros to this node. Document m4_include & m4_sinclude.
7657 Move m4_undefine to alphabetical order.
7659 2005-06-07 Paul Eggert <eggert@cs.ucla.edu>
7661 * README: Recommend GNU M4 1.4.3 or later.
7662 * doc/autoconf.texi (Introduction): Likewise.
7663 Reword to avoid some formatting glitches.
7664 Use "#!/bin/sh", not "#! /bin/sh"; the space isn't needed these days.
7665 Clarify explanation of HP compiler bug.
7666 Redo example output tp match current CVS snapshot.
7667 Use @example.org in email addresses when the examples
7668 might get inadvertently cut-and-pasted into user code.
7669 Remove example of autom4te usage that doesn't seem to work now.
7670 Use modern AC_INIT (except when the example is meant to be
7671 shown with Autoconf 2.13).
7672 Update ksh info for Solaris 9 and later.
7673 KB -> kB.
7674 Modernize description of Automake versions a bit.
7675 Don't claim a future version of Autoconf is near.

7682 Reword to avoid some formatting glitches.
7683 * doc/installt.exi: Reword to avoid some formatting glitches.
7685 * doc/autoconf.texi (Limitations of Builtins) <case>: Mention
7686 Tru64 ksh pattern matching bug. Reported against Libtool by
7687 Albert Chin <libtool@mlists.thewrittenword.com> and
7688 Nicolas Joly <njoly@pasteur.fr>.
7690 2005-06-06 Stepan Kasal <kasal@ucw.cz>
7692 m4_cdr of one-member list was [[]] (one-member list containing an
7693 empty string) instead of [] (an empty list. Callers were skewed to
7694 match this misbehaviour. As a consequence of this:
7695 - m4_foreach([x], [], [foo]) expanded to `foo', while
7696 - the expansion of m4_foreach([x], [[]], [foo]) was empty.
7697 This bug has been fixed:
7699 * lib/m4sugar/m4sugar.m4 (m4_cdr): If only one argument is given,
7700 expand to an empty string; print error msg if called without
7701 an argument list.
7702 (m4_foreach, m4_map, m4_map_sep): Don't expect the previous
7703 misbehaviour; handle [] and [[]] correctly.

7711 2005-06-06 Ralf Menzel <menzel@ls6.cs.uni-dortmund.de> (trivial change)
7713 * doc/autoconf.texi (Limitations of Usual Tools): Solaris' awk cannot
7714 swallow records with more than 99 fields.
7715 * lib/autotest/general.m4 (AT_INIT): Use the awk builtin `split' to
7716 parse the long line.
7718 2005-06-04 Stepan Kasal <kasal@ucw.cz>
7720 * doc/autoconf.texi (Limitations of Usual Tools): AIX awk cannot
7721 swallow literals longer than 399. Reported by Ralf Wildenhues.

7727 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Find g95 in addition
7728 to gfortran, and make these the first two compiler names
7729 checked (following the general autoconf preference for gcc).
7731 2005-06-03 Stepan Kasal <kasal@ucw.cz>
7733 * tests/Makefile.am (check_SCRIPTS): Set to $(wrappers).
7734 (DISTCLEANFILES): Remove $(check_SCRIPTS).
7735 (testsuite): Make sure autotest.m4f is up-to-date before using it.

7739 * lib/autotest/general.m4 (AT_INIT): Don't create a regular
7740 expression of unbounded size when processing the --list
7741 option. This runs afoul of a limit of 399 bytes per regular
7742 expression on AIX. Problem reported by Ralf Wildenhues.

7751 Reword description of line replacement.
7753 2005-05-31 Dan Manthey <dan_manthey@partech.com>
7755 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Output variables may
7756 now contain newlines, and substituted files must be referenced on
7757 a line alone; the sed scripts to substitute them are now very
7758 different.
7759 (_AC_SED_CMD_LIMIT): Added; single place to store limit on how many
7760 commands can be put in a sed script portably.
7761 * doc/autoconf.texi (Setting Output Variables): Document above

7773 * tests/local.at: Don't attempt to check for negated character
7774 classes in shell scripts. The test was too brittle.
7776 2005-05-25 Stepan Kasal <kasal@ucw.cz>
7778 * bin/autoconf.as: Don't use "shift 2"; it's not portable enough.
7779 * doc/autoconf.texi (Limitations of Builtins): Document this
7780 limitation.
7782 2005-05-24 Stepan Kasal <kasal@ucw.cz>

7792 messages when ac_unique_file is not found.
7793 (AC_CONFIG_MACRO_DIR): Simplify the `if' at the end.
7794 (AC_MSG_CHECKING, AC_MSG_RESULT): Put braces around the two echo

7810 * lib/autoconf/status.m4 (_AC_SRCDIRS): Rename ...
7811 (ac_top_builddir): ... this ...
7812 (ac_top_build_prefix): ... to this; the old name is also kept, for
7813 backward compatibility.
7814 (ac_top_builddir_sub): New variable, without the trailing slash,
7815 always nonempty.
7816 (_AC_OUTPUT_FILES): s/@top_builddir@/$ac_top_builddir_sub/

7830 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Don't m4_quote the second
7831 argument to m4_foreach. I guess it was necessary in the past,
7832 but I think it's a no-op now.
7834 2005-05-17 Stepan Kasal <kasal@ucw.cz>
7836 * lib/autoconf/general.m4 (_AC_INIT_HELP): Merge two consecutive
7837 ``cat <<_ACEOF'' commands to one.
7838 (_AC_CANONICAL_SPLIT): Use expr, not ``echo|sed.''
7839 * lib/autoconf/status.m4: On various places, use expr instead of
7840 ``echo|sed.''
7841 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST):
7842 (_AC_CONFIG_SPLIT_FILE_IN): New macros, to factor out common code.
7843 * lib/autotest/general.m4 (AT_INIT): Use expr to get the numbers from
7844 a range.
7845 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Use awk to search for
7846 the wrong patterns between ``case'' and ``esac.'' The previous
7847 code had false positives.
7849 2005-05-14 Alexandre Duret-Lutz <adl@gnu.org>
7851 * lib/autoconf/functions.m4 (_AC_LIBOBJ_ALLOCA): Prepend ${LIBOBJDIR},
7852 as on 2005-05-02.
7853 * doc/autoconf.texi (Particular Functions) <AC_FUNC_ALLOCA>:
7854 Mention LIBOBJDIR.

7897 check.
7898 * lib/m4sugar/m4sugar.m4 (m4_bmatch): Halt with error if we don't get
7899 enough arguments, similarly as in m4_bpatsubsts.
7901 2005-05-12 Stepan Kasal <kasal@ucw.cz>
7903 * lib/autoconf/status.m4 (_AC_SRCDIRS): Simplify the computation

7906 2005-05-11 Stepan Kasal <kasal@ucw.cz>
7908 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Make the check
7909 for absolute directory names in one loop.
7910 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Handle
7911 abbreviations of --version and --debug.
7913 2005-05-10 Paul Eggert <eggert@cs.ucla.edu>
7915 * doc/autoconf.texi (Autoconf Language): Be more precise about
7916 quoting rules. Problems noted by Stepan Kasal.
7917 Also, throughout this document, be more careful about white space.
7918 "blank", "white space", and "space" all have different meanings
7919 and we should be careful to say what we mean.
7921 2005-05-05 Paul Eggert <eggert@cs.ucla.edu>
7923 Fix C++ related problems reported by Werner Lemberg.
7924 * doc/autoconf.texi (C++ Compiler): Mention .cpp extension.
7925 * lib/autoconf/c.m4 (AC_LANG(C++)): Set ac_ext to .cpp, not .cc.
7926 * lib/autoconf/types.m4 (AC_TYPE_SIGNAL): Simplify test, to
7927 avoid problems with C++ and throw.
7928 * tests/compile.at: .cpp, not .cc.
7930 * tests/semantics.at: Prepend LIBOBJDIR, as per 2005-05-02 change.
7932 2005-05-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7934 * doc/autoconf.texi (Generic Functions): Typos.
7936 2005-05-02 Gary V. Vaughan <gary@gnu.org>
7938 * lib/autoconf/general.m4 (_AC_LIBOBJS_NORMALIZE): Prepend each
7939 object named in LIBOBJS and LTLIBOBJS with the ${LIBOBJDIR}, as
7940 set by latest automake.
7942 2005-05-01 Paul Eggert <eggert@cs.ucla.edu>
7944 * doc/autoconf.texi (Limitations of Usual Tools): "expr '' \| ''"
7945 outputs 0 on GNU/Linux these days.
7947 2005-04-29 Paul Eggert <eggert@cs.ucla.edu>
7949 * doc/autoconf.texi (Autoconf Language): Add more description
7950 about quoting heuristics.
7951 (Limitations of Builtins): Describe "set -" problems.
7953 2005-04-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7955 * lib/autotest/general.m4 (AT_KEYWORDS): Separate by space,
7956 not newline.
7958 * doc/autoconf.texi (External Software): Replace AC_DEFINE_UNQUOTED
7959 by AC_DEFINE; it was a mistake.
7960 From bug reported against libtool by Dalibor Topic <robilad@kaffe.org>.
7962 2005-04-25 Stepan Kasal <kasal@ucw.cz>
7964 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): A tiny optimization.
7966 2005-04-22 Stepan Kasal <kasal@ucw.cz>
7968 * doc/autoconf.texi (External Software): Quadrigraphs are not
7969 processed correctly in AS_HELP_STRING; avoid this in the examples.
7970 * lib/m4sugar/m4sh.m4 (AS_HELP_STRING): Add a FIXME about quadrigraphs.
7971 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Likewise; and rephrase the
7972 comment and reduce m4_default([foo], []) to [foo].
7973 (m4_strip): Update the explanation.
7975 2005-04-19 Paul Eggert <eggert@cs.ucla.edu>
7977 * lib/autoconf/general.m4 (_AC_INIT_PREPARE, _AC_RUN_IFELSE):
7978 Remove core.conftest.* too; it's generated by Tru64 5.1.
7979 Problem reported by Jennis Pruett.
7980 * lib/autoconf/functions.m4
7981 (AC_FUNC_SETVBUF_REVERSED, AC_FUNC_UTIME_NULL):
7982 Don't bother to remove core files; AC_RUN_IFELSE should do that
7983 for you.
7985 2005-04-19 Stepan Kasal <kasal@ucw.cz>
7987 * lib/m4sugar/m4sugar.m4 (m4_bpatsubsts): Add the b- to comment, too.

7997 the comment.
7999 2005-04-14 Gregorio Guidi <greg_g@gentoo.org>
8001 * doc/autoconf.texi (External Software, Package Options): Add
8002 examples showing how to implement --with-* and --enable-* options.
8004 2005-04-13 Paul Eggert <eggert@cs.ucla.edu>
8006 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Look for configure.ac
8007 as well as configure.in. Problem reported by Gregorio Guidi.
8009 2005-04-10 Paul Eggert <eggert@cs.ucla.edu>
8011 * doc/autoconf.texi (Particular Functions): Use gnulib's current
8012 pattern for alloca snippet.
8014 2005-04-04 Stepan Kasal <kasal@ucw.cz>
8016 * lib/autotest/general.m4 (_AT_DECIDE_TRACEABLE): Fix a typo.
8018 2005-04-01 Stepan Kasal <kasal@ucw.cz>
8020 * doc/autoconf.texi (Generic Programs): Fix a typo.
8022 2005-04-01 Paul Eggert <eggert@cs.ucla.edu>
8024 * lib/autotest/general.m4 (AT_INIT): Don't assume that "date +%s"
8025 fails if %s isn't supported. Problem reported by Ralf Wildenhues.
8027 2005-03-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8029 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS):
8030 Merge `-z option' as well for the benefit of Solaris link flags. Pass
8031 whole-archive (-zallextract, -zdefaultextract) options in the hope of
8032 unique libraries, for the Sun Fortran 95 8.0 compiler. Bug reported
8033 against Libtool by Yury Puhalsky <pooh@cryptopro.ru>.
8035 2005-03-22 Paul Eggert <eggert@cs.ucla.edu>
8037 * NEWS: The configure command now warns you if you attempt to use
8038 a directory whose name contains a special character like space,
8039 newline, or "\".
8040 * doc/autoconf.texi (Installation Directory Variables): Allow
8041 "," in file names. Do not use \@; it's not a portable regexp.
8042 * bin/Makefile.am (edit): Likewise.
8043 * lib/Makefile.am (edit): Likewise.
8044 * tests/Makefile.am (edit): Likewise.
8045 * tests/semantics.at: Likewise.
8046 * tests/torture.at: Likewise.
8047 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Likewise.
8048 * lib/autoconf/status.m4 (_AC_SRCDIRS): Likewise.
8049 * doc/autoconf.texi (File System Conventions): Warn about
8050 unportable file names.
8051 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): New macro.
8052 (AC_INIT): Use it.
8053 (_AC_INIT_SRCDIR): Use ac_pwd rather than invoking pwd.
8054 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Propagate
8055 ac_pwd, and quote srcdir.
8056 * lib/autotest/general.m4 (AT_INIT): Quote file name args.
8058 * doc/autoconf.texi: Fix some systematic formatting problems.
8059 ".)" needs a following @: if not at the end of a sentence, and
8060 similarly for "!)". "etc." should be preceded by a comma.
8061 "n-th" -> "@var{n}th". pdksh is still buggy, so update its date.
8063 2005-03-22 Bruno Haible <bruno@clisp.org>
8065 * doc/autoconf.texi (Input): Mention that AC_CONFIG_AUX_DIR's
8066 argument is often called 'build-aux'.
8068 2005-03-07 Stepan Kasal <kasal@ucw.cz>
8070 * doc/autoconf.texi (Quotation Rule Of Thumb): Mention that the
8071 macro AC_TRY_LINK is obsolete.
8072 (Installation Directory Variables): Change `AC_OUTPUT_FILES' to
8073 `AC_CONFIG_FILES'.
8075 2005-02-24 Stepan Kasal <kasal@ucw.cz>
8077 * lib/autoconf/c.m4 (AC_PROG_CC): Be more careful to skip
8078 `/usr/ucb/cc'; use `cl.exe' to distinguish the MS compiler
8079 from a Common Lisp's `cl'.
8080 (AC_PROG_CXX): Behave according to the documentation: don't
8081 search for $ac_tool_prefix$CCC and $CCC, just set CXX=$CCC;
8082 make the variable CCC precious; use `cl.exe', not `cl'.
8084 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
8085 Alexandre Duret-Lutz <adl@gnu.org>
8087 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin from
8088 /dev/null, as "configure" shouldn't read stdin, and this insulates
8089 us from problems (e.g., when testing for "cl"). Also, do this
8090 redirection before invoking "hostname" or "uname", and keep the
8091 original input stream available via...
8092 (AS_ORIGINAL_STDIN_FD): ... this new macro.
8093 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't
8094 bother with "</dev/null" since it's now done at the top of
8095 'configure'.
8096 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Likewise.
8097 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
8098 * lib/autoconf/programs.m4 (_AC_PATH_PROG_FLAVOR_GNU): Likewise.
8099 * doc/autoconf.texi (File Descriptor Macros): New section.
8100 (Printing Messages): Mention it.
8101 * tests/base.at (Input/Output): New test.
8103 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
8105 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N_PREPARE): Don't set ECHO_C to
8106 newline if neither \c nor -n work, as that would output two
8107 newlines. Prefer -n to \c. Reported by Stepan Kasal.
8109 2005-02-12 Stepan Kasal <kasal@ucw.cz>
8111 * lib/m4sugar/m4sh.m4 (AS_IF): Define by m4_defun, not m4_define.
8112 This causes that any required macros inside will get before the if.
8113 * doc/autoconf.texi (autom4te.cache): A typo.
8115 2005-02-12 Paul Eggert <eggert@cs.ucla.edu>
8117 Undo previous change, except keep the change to
8118 lib/autoconf/programs.m4 that replaced grep with shell
8119 pattern-matching. This is because net-snmp configure reads stdin.
8120 Reported by Noah Misch.
8122 2005-02-11 Paul Eggert <eggert@cs.ucla.edu>
8124 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin
8125 from /dev/null, as "configure" shouldn't read stdin, and this
8126 insulates us from problems (e.g., when testing for "cl").
8127 Suggested by Alexandre Duret-Lutz. Also, do this redirection
8128 before invoking "hostname" or "uname".
8129 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
8130 _AC_LINK_IFELSE): Undo previous change, as it's no longer needed.
8131 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Don't bother with
8132 "</dev/null" since it's now done at the top of 'configure'.
8133 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
8134 * lib/autoconf/programs.m4 (_AC_PATH_PROG_FLAVOR_GNU): Likewise.
8135 Also, replace grep with shell pattern-matching, to save a process.
8137 2005-02-10 Paul Eggert <eggert@cs.ucla.edu>
8139 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
8140 _AC_LINK_IFELSE): Redirect stdin to /dev/null, in an attempt to
8141 avoid thinking that Allegro Common Lisp's "cl" command is a C++
8142 compiler.
8144 2005-02-09 Paul Eggert <eggert@cs.ucla.edu>
8146 * doc/autoconf.texi (Limitations of Usual Tools): Document that
8147 grep -q isn't portable. Improve grep -s explanation.
8148 Problem reported by Dan Manthey.
8150 2005-02-08 Paul Eggert <eggert@cs.ucla.edu>
8152 * doc/autoconf.texi (Special Shell Variables): Clarify
8153 PATH_SEPARATOR wording; fix typo in IFS. Reported by Gary V. Vaughan.
8155 2005-02-07 Paul Eggert <eggert@cs.ucla.edu>
8157 * doc/autoconf.texi: Use @acronym for DJGPP.
8158 Fix some @code's that should have been @env's, and vice versa.
8159 Sort environment variable names.
8160 Mention that shells no longer inherit IFS.
8161 Don't recommend PATH_SEPARATOR=';' so strongly.
8162 Mention that $RANDOM might expand to the empty string.
8163 "symlink" and "soft link" -> "symbolic link".
8164 Improve mktemp description (reported by Bruno Haible).
8166 2005-02-05 Paul Eggert <eggert@cs.ucla.edu>
8168 * tests/foreign.at (Libtool): Don't overquote AT_SETUP arg.
8169 * tests/m4sh.at (AS_DIRNAME, AS_BASENAME, AS_MKDIR_P, AS_HELP_STRING):
8170 Likewise.
8171 * tests/semantics.at (AC_C_BIGENDIAN, AC_PATH_PROG & AC_PATH_PROGS):
8172 Likewise.
8174 2005-02-04 Paul Eggert <eggert@cs.ucla.edu>
8176 * NEWS: Mention AT_COPYRIGHT.
8178 * tests/local.at (AT_CMP): Use diff directly on input files rather
8179 than copying them.
8181 * lib/autoconf/programs.m4 (AC_PROG_SED): Don't look in
8182 /usr/xpg4/bin since that sed dumps core (at least on Solaris 8).
8184 2005-02-04 Noah Misch <noah@cs.caltech.edu>
8185 and Paul Eggert <eggert@cs.ucla.edu>
8187 * tests/autotest.at (Empty test suite): New test.
8188 * tests/torture.at (Substitute and define special characters)
8189 (Substitute a 2000-byte string, Define to a 2000-byte string)
8190 (Substitute a newline, Define a newline): New tests.
8192 2005-02-04 Noah Misch <noah@cs.caltech.edu>
8194 * lib/m4sugar/m4sugar.m4 (m4_re_string, m4_re_word): Revert 2002-03-04.
8195 * tests/local.at (AT_CHECK_M4SUGAR): Add `m4sugar' to keywords.
8196 (AT_CHECK_ENV): Ignore LTLIBOBJS, FC variables, EGREP, FGREP, and SED.
8197 * tests/m4sugar.at (AT_CHECK_M4SUGAR_TEXT, AT_CHECK_M4RE): New macros.
8198 (Standard regular expressions): New test.
8199 (m4_warn, m4_require: circular dependencies, m4_text_wrap): Strip
8200 excess test name quoting.
8201 * tests/semantics.at (AC_CHECK_HEADERS_OLD, AC_CHECK_HEADERS_NEW): Pass
8202 CPPFLAGS to `configure' instead of setting it in `configure'.
8204 * lib/m4sugar/m4sh.m4 (AS_UNAME): Try only /usr/bin/hostinfo, not
8205 any `hostinfo' in $PATH, since hostinfo.exe is a popular file name
8206 on some platforms.
8208 * lib/autoconf/fortran.m4 (AC_LANG(Fortran), AC_FC_SRCEXT):
8209 s/FC_SRCEXT/ac_fc_srcext/; s/FCFLAGS_SRCEXT/ac_fcflags_srcext/.
8211 * tests/local.at (AT_CMP): New macro.
8212 (AT_DATA_AUTOCONF): Do not call AC_PROG_GREP.
8213 (AC_SAVE_STATE): Move environment grep...
8214 (AT_CHECK_ENV): to here. Filter out `'$''. Use AT_CMP.
8215 (AT_CONFIG_CMP): New macro.
8216 (AT_CHECK_MACRO): Run `configure' twice with cache and compare results.
8217 * tests/c.at (Extensions): Do not exit early.
8218 * tests/atlocal.in: Inherit $GREP.
8220 * lib/autoconf/c.m4 (_AC_C_STD_TRY): New macro.
8221 (_AC_PROG_CC_C89, _AC_PROG_CC_C99): Use it.
8223 * lib/autoconf/general.m4 (_AC_INIT_COPYRIGHT): Update for 2005.
8224 (AC_COPYRIGHT): Factor header comment portion out and move into...
8225 * lib/m4sugar/m4sh.m4 (AS_COPYRIGHT): This.
8226 * lib/autotest/general.at (AT_COPYRIGHT): New macro.
8227 (AT_INIT): Add Autotest copyright notice. Display copyright notices in
8228 --version output.
8229 * tests/local.at: Add Autoconf test suite copyright notice.
8230 * doc/autoconf.texi (Writing testsuite.at): Document AT_COPYRIGHT.
8232 2005-02-04 Bruno Haible <bruno@clisp.org>
8233 and Paul Eggert <eggert@cs.ucla.edu>
8235 * doc/autoconf.texi (Limitations of Usual Tools): New mkstemp entry.
8237 2005-02-03 Paul Eggert <eggert@cs.ucla.edu>
8239 * lib/m4sugar/m4sugar.m4 (m4_re_escape): Escape ?, ^, \, $ too;
8240 this fixes a bug tickled by the AT_CAPTURE_FILE change noted below.
8242 Try not to generated lines of unlimited length, as POSIX places a
8243 2047-byte limit on line length of portable text files.
8244 * lib/autoconf/general.m4 (AC_SUBST, AC_SUBST_FILE):
8245 Use newline as a separator, not space.
8246 * lib/autotest/general.m4 (AT_TESTED, AT_KEYWORDS): Likewise.
8247 (AT_CAPTURE_FILE): Use space-backslash-newline as a separator, not
8248 space.
8250 2005-02-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8252 * lib/m4sugar/m4sh.m4 (_AS_SHELL_FN_WORK): Move func_* to
8253 as_func_*. Add test to check whether positional parameters
8254 are restored after function return.
8256 2005-02-02 Paul Eggert <eggert@cs.ucla.edu>
8258 * doc/autoconf.texi (Special Shell Variables): Mention _,
8259 BIN_SH, DUALCASE. Say that variables other than "status" are safe
8260 if they contain a lower-case letter. The DUALCASE problem was
8261 reported by Ralf Wildenhues.
8263 * bin/autoconf.as: Don't exit with status 0 after write failure
8264 with --help or --version.
8265 * lib/autoconf/general.m4 (_AC_INIT_HELP, _AC_INIT_VERSION): Likewise.

8303 Simplify the implementation of m4_require (a.k.a. AC_REQUIRE).
8304 Update the long comment explaining it.
8306 m4_require no longer writes an ``is required by'' line to the
8307 execution stack. It contains only one bit of non-redundant
8308 information: that the macro was required, not called. And even
8309 this bit is useless in most situations: have you ever met a macro
8310 which both calls and requires the same macro?
8312 * lib/m4sugar/m4sugar.m4 (_m4_defun_pro): Don't push a diversion...
8313 (_m4_defun_pro_outer): ... only via this macro, for the outermost

8321 * tests/m4sugar.at (m4_require): Expect output without the
8322 ``is required by'' messages.
8324 2005-01-28 Paul Eggert <eggert@cs.ucla.edu>
8326 * doc/autoconf.texi (Limitations of Usual Tools): Recommend X
8327 rather than x for expr.
8329 * lib/autoconf/lang.m4 (_AC_COMPILER_OBJEXT): Avoid subshells when
8330 this is safe.
8331 * lib/autoconf/programs.m4 (AC_PROG_EGREP, AC_PROG_FGREP): Likewise.
8332 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Likewise.

8345 support.
8346 * bin/autoheader.in: Pass $force to update_file so that
8347 config.h.in is always recreated when --force.

8351 * doc/autoconf.texi (Introduction): Update Peter Simons' address.
8353 2005-01-21 Paul Eggert <eggert@cs.ucla.edu>
8355 * doc/autoconf.texi (Limitations of Builtins): Clarify that

8358 2005-01-20 Paul Eggert <eggert@cs.ucla.edu>
8360 * doc/autoconf.texi (Shell Substitutions): Fix typo in case statement.
8361 Warn about newline stripping in `` and $(). Update Solaris
8362 version to 9.

8364 X insulates us from future changes to Posix.
8365 (Limitations of Usual Tools): For AS_DIRNAME, warn about newline
8366 stripping.
8368 2005-01-19 Stepan Kasal <kasal@ucw.cz>

8388 <https://bugzilla.redhat.com/beta/show_bug.cgi?id=143852>.
8390 2005-01-05 Alexandre Duret-Lutz <adl@gnu.org>
8392 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Define datarootdir,

8414 (_m4_divert_n_stack): New macro; the expansion is
8415 <newline>m4_divert_stack, if m4_divert_stack is defined, and void
8416 otherwise.
8417 (m4_divert, m4_divert_push, m4_divert_pop, m4_init): Use it.
8418 (m4_divert_push, m4_divert_pop, _m4_defun_epi): Don't expand the word
8419 stored in _m4_divert_diversion or _m4_divert_dump.
8420 (m4_divert_pop): When the parameter is given, compare the symbolic
8421 name with the last diversion pushed on the stack. Previously, the
8422 current diversion was compared with the numeric value of the
8423 diversion given as the parameter.
8424 (m4_require): If the macro hasn't been expanded yet, call ...
8425 (_m4_require_call): this new macro.

8458 * bin/autoreconf.in (autoreconf_current_directory): AM_INIT_AUTOMAKE

8460 not essential. Reported by Magnus Therning.
8461 * tests/torture.at (autoreconf.): New banner.
8462 (autoreconf and non-AC configure): Rename to `Non-Autoconf
8463 AC_CONFIG_SUBDIRS'.

8511 * lib/autoconf/status.m4: Quote ``$tmp'' in many places.
8512 * lib/m4sugar/m4sh.m4 (AS_TMPDIR): Fix the comment, as traps are

8639 autoscan.1, autoupdate.1, ifnames.1, config.guess.1, config.sub.1):

8726 (_AC_DEFINE_Q): ... a new macro; simplify the condition about the
8727 value of the #define--default to 1, iff the macro was called
8728 with exactly one parameter.
8730 2004-12-02 Paul Eggert <eggert@cs.ucla.edu>
8732 * lib/autoconf/functions.m4 (AC_FUNC_MEMCMP): Use
8733 "char c = '\200';" rather than "char c = 0x80;" as the
8734 latter doesn't conform to the strict C standard due to
8735 overflow on signed char hosts.
8737 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Prefer -qlanglvl=extc89
8738 to -qlanglvl=ansi. We don't want to disable extensions.
8740 2004-11-29 Paul Eggert <eggert@cs.ucla.edu>
8742 * doc/autoconf.texi (Particular Programs): @code{$PATH} -> @env{PATH}.
8743 (Using Autotest, testsuite Scripts, Writing testsuite.at):
8744 Reword slightly to avoid some English-language problems noted

8794 simplify the examples and improve their quoting.
8796 2004-11-13 Stepan Kasal <kasal@ucw.cz>
8798 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Don't check
8799 the $1_found variable, don't test whether the file is executable;
8800 Both things are checked ...
8801 (_AC_PATH_PROG_FEATURE_CHECK): ... here; AS_EXECUTABLE_P replaces
8802 the former ``test -f''.
8803 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Fix a typo.
8805 2004-11-10 Paul Eggert <eggert@cs.ucla.edu>

8808 use cp -R instead.
8810 2004-11-10 Derek R. Price <derek@ximbiot.com>
8812 * doc/autoconf.texi (Limitations of Usual Tools): Note `cp -r'
8813 limitations. Reorder paragraphs for clarity.
8815 2004-10-11 Paul Eggert <eggert@cs.ucla.edu>
8817 * doc/autoconf.texi: Standardize spelling of "Posix" (as opposed
8818 to "POSIX" or "@acronym{POSIX}"), and similarly for "DOS
8819 variants", "Unix", and some related minor wording fixups.
8821 (Shellology, Special Shell Variables): Document that the Zsh
8822 problem with NULLCMD was fixed in zsh 3.1.6-dev-18. Thanks

8834 2004-09-22 Paul Eggert <eggert@cs.ucla.edu>
8836 * doc/autoconf.texi (auindex): New macro.
8837 (AU_DEFUN): Use it to fix the bug when the index contained AC_AU_DEFUN.
8838 Problem reported by Stepan Kasal.
8840 2004-09-05 Paul Eggert <eggert@cs.ucla.edu>
8842 Fix problems reported by Andreas Buening in:
8843 http://lists.gnu.org/archive/html/autoconf-patches/2004-04/msg00004.html
8844 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Set SHELL=/bin/sh
8845 in test makefile.
8846 * lib/autotest/general.m4 (AT_INIT): Don't assume /dev/null is
8847 readable; it's not true in OS/2-emx.
8849 2004-09-04 Paul Eggert <eggert@cs.ucla.edu>
8851 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): If xmkmf returns
8852 "/usr/include", clear ac_x_includes instead of leaving it as "no"
8853 (trivial change). Problem and patch reported by Andrew Church in:
8854 http://lists.gnu.org/archive/html/bug-autoconf/2004-04/msg00016.html
8856 2004-09-03 Paul Eggert <eggert@cs.ucla.edu>

8861 Also, fix some minor spacing and punctuation bugs.
8863 2004-09-02 Akim Demaille <akim@epita.fr>
8865 * doc/autoconf.texi (Limitations of Builtins): Swap "cd" and

8883 * Makefile.cfg (wget_files): Remove config.guess, config.sub,
8884 texinfo.tex for now (done by hand now).
8885 * Makefile.maint (wget_files, cvs_files):
8886 Remove ansi2knr.c; nobody uses it.
8887 (ansi2knr.c-url_prefix): Remove.
8888 (cvs-update): Fix test for failure. I don't know why it ever
8889 worked...
8891 * doc/autoconf.texi: Update URLs, some of which went stale.
8892 Use @uref rather than @href.
8894 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Have configure
8895 handle "--" as per POSIX. Suggested by Paul Pogonyshev.
8897 * config/config.guess, config/config.sub, config/elisp-comp,
8898 config/install-sh, config/mkinstalldirs, config/texinfo.tex,
8899 doc/fdl.texi, doc/standards.texi: Sync with master copy.
8901 * NEWS, TODO, configure.ac, bin/autoscan.in,
8902 bin/autoupdate.in, bin/ifnames.in, doc/autoconf.texi,
8903 doc/install.texi, lib/Autom4te/Configure_ac.pm,

8907 lib/m4sugar/m4sugar.m4, tests/local.at, tests/m4sh.at,
8908 tests/tools.at, tests/torture.at:
8909 Use "file name" rather than "filename" or "path",
8910 to be consistent with the terminology of the GNU coding standards.
8912 2004-08-19 Paul Eggert <eggert@cs.ucla.edu>
8914 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C),
8915 AC_C_LONG_DOUBLE): Undo 2004-06-04 change, as it didn't work with
8916 HP-UX 11.23 cc/aCC or Tru64 4.0 cc. Problem reported by Noah Misch in
8917 <http://lists.gnu.org/archive/html/autoconf/2004-07/msg00004.html>.
8919 More fixes to support spaces in the name of the build directory.
8920 This isn't a complete fix but it's an improvement.
8922 * bin/autoconf.as (autom4te_options): New var.
8923 Use it instead of appending to AUTOM4TE, so that we can allow
8924 spaces in the build directory's absolute name.
8925 * bin/autoheader.in ($autoconf): Allow spaces in file names.
8926 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP, _AT_CHECK,
8927 AT_CHECK_NOESCAPE): Likewise.
8928 * tests/wrapper.as (testdir, AUTOM4TE_CFG, autom4te_perllibdir,
8929 main program): Likewise.
8931 2004-08-18 Paul Eggert <eggert@cs.ucla.edu>
8933 * lib/autoconf/general.m4 (_AC_INIT_HELP): Quote $ac_popdir uses.
8934 From Ralf Corsepius in:

8937 2004-08-12 Paul Eggert <eggert@cs.ucla.edu>
8939 * doc/autoconf.texi (Function Portability): Document isinf and
8940 and isnan. From a suggestion by Kevin Ryde.
8942 * lib/Autom4te/General.pm (END): Return correct exit status even
8943 if unlink succeeds and sets $?. Needed with Solaris 8's perl 5.00503.
8945 2004-08-09 Paul Eggert <eggert@cs.ucla.edu>
8947 * tests/torture.at (Deep Package): Use configure.in, not configure.ac,
8948 for compatibility with Automake 1.4. Reported by J C Fitzgerald in
8949 <http://lists.gnu.org/archive/html/bug-autoconf/2003-08/msg00051.html>.
8951 2004-08-04 Alexandre Duret-Lutz <adl@gnu.org>
8953 * lib/autoconf/general.m4 (AC_REQUIRE_AUX_FILE): New empty macro.
8954 (AC_CANONICAL_BUILD): Call it to require config.sub and config.guess.
8955 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Likewise for install-sh.
8956 * doc/autoconf.texi (Input): Document AC_REQUIRE_AUX_FILE.
8957 * lib/autom4te.in (Automake-preselections): Preselect
8958 AC_REQUIRE_AUX_FILE. Automake 1.10 will trace it.
8960 2004-08-02 Alexandre Duret-Lutz <adl@gnu.org>
8962 * lib/autom4te.in (Automake-preselections): Preselect
8963 AC_CANONICAL_BUILD and AC_CANONICAL_TARGET. Automake 1.9.1 will
8964 trace them.
8966 2004-07-29 Paul Eggert <eggert@cs.ucla.edu>
8968 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): Set BIN_SH, for
8969 Tru64.
8970 * doc/autoconf.texi (Shellology): Mention BIN_SH.
8971 Document problem with "`""`" in pdksh POSIX mode.
8973 2004-07-27 Paul Eggert <eggert@cs.ucla.edu>
8975 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): Use "set -o posix"
8976 with pdksh, too. Problem reported by Patrick Welche via
8977 Gary V. Vaughan.
8978 * doc/autoconf.texi (Shellology): Note that set -o posix is
8979 useful for pkdsh, too.
8981 2004-06-24 Paul Eggert <eggert@cs.ucla.edu>
8983 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Require
8984 _AS_UNSET_PREPARE, so that we can use $as_unset directly.
8985 Don't fail if ENV or BASH_ENV is readonly.
8986 (AS_SHELL_SANITIZE): Don't fail if ENV, MAIL, MAILPATH, LC_ALL,
8987 etc. are read only. Problem reported by Ludovic Courtes.
8989 2004-06-23 Noah Misch <noah@cs.caltech.edu>
8991 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): If the shell is
8992 zsh, disable GLOB_SUBST to avoid backslash handling problems.
8993 (trivial change)
8995 2004-06-04 Paul Eggert <eggert@cs.ucla.edu>
8997 * doc/autoconf.texi (File System Conventions): Warn about
8998 names like "aux". Problem reported by Eric Blake.
9000 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY (C)): Use division
9001 by zero instead of array size, so that we can use any arithmetic
9002 constant expression (instead of requiring an integer constant
9003 expression). This allows us to test expressions like DBL_MAX <
9004 LDBL_MAX, which didn't conform to the C standard using the old
9005 method.
9006 (AC_C_LONG_DOUBLE): Put back in the tests for LDBL_MAX and LDBL_EPSILON,
9007 now that we can do floating-point tests at compile time.
9009 2004-06-02 Paul Eggert <eggert@cs.ucla.edu>
9011 * lib/autoconf/c.m4 (AC_C_LONG_DOUBLE): Don't check LDBL_MAX
9012 and LDBL_EPSILON, as the resulting expression isn't an
9013 integer constant expression and violates the C standard.
9014 Problem reported by Nelson H. F. Beebe. Also, check
9015 for "L" suffix, and check that long double doesn't have
9016 worse range or precision than double, that mixed-mode
9017 arithmetic doesn't generate a diagnostic, that double
9018 constants fit in long double.
9020 2004-06-03 Kevin Ryde <user42@zip.com.au>
9022 * doc/autoconf.texi (Function Portability): Add notes on free(NULL),
9023 malloc(0) and realloc(NULL,size).
9025 * doc/autoconf.texi (Shell Substitutions): Spelling error reported by
9026 Bob Proulx.
9028 2004-05-31 Paul Eggert <eggert@cs.ucla.edu>
9030 * lib/autoconf/headers.m4 (HAVE_STDBOOL_H): Detect _Bool bug
9031 in HP aC++/ANSI C B3910B A.05.55 [Dec 04 2003]. Problem reported
9032 by Jim Meyering.
9034 2004-05-26 Paul Eggert <eggert@cs.ucla.edu>
9036 * doc/autoconf.texi (Limitations of Builtins): Mention that ! COMMAND
9037 can be rewritten using if-then-else. Suggested by Bruno Haible.
9039 2004-05-25 Paul Eggert <eggert@cs.ucla.edu>
9041 * doc/autoconf.texi (testsuite Scripts): Fix typo.
9042 Problem reported by Stepan Kasal.
9044 2004-05-24 Paul Eggert <eggert@cs.ucla.edu>
9046 * tests/Makefile.am (autoconfdir): Fix to match comment (trivial
9047 change). Patch reported by Ralf Wildenhues in
9048 <http://mail.gnu.org/archive/html/bug-autoconf/2004-05/msg00092.html>.
9050 * lib/autoconf/functions.m4 (AC_FUNC_MBRTOWC): Don't assume that a
9051 function F exists if the compiler and linker let you compile an
9052 expression like (F != 0). Recent versions of GCC optimize away
9053 the reference to F in that case, since every function address must
9054 be nonzero, so the link succeeds even if F does not exist.
9055 Problem reported by Manu in
9056 <http://mail.gnu.org/archive/html/bug-gnu-utils/2004-05/msg00060.html>.
9058 * doc/autoconf.texi (Systemology): Standardize on the spelling of
9059 "Unix". Many uses changed.
9060 (Limitations of Builtins): Explain better why the ! command isn't
9061 portable.
9063 2004-05-22 Alexandre Duret-Lutz <adl@gnu.org>
9065 * lib/autom4te.in (Automake-preselections): Preselect
9066 LT_SUPPORTED_TAG in lieu of AC_LIBTOOL_TAGS.
9068 2004-05-19 Kevin Ryde <user42@zip.com.au>
9070 * doc/autoconf.texi (Function Portability): Add strerror_r, cross
9071 referencing AC_FUNC_STRERROR_R.
9073 * doc/autoconf.texi (Particular Functions): In AC_FUNC_CLOSEDIR_VOID,
9074 note pessimistic assumption when cross compiling.
9076 2004-05-16 Paul Eggert <eggert@cs.ucla.edu>
9078 * doc/autoconf.texi (Limitations of Make): Note that BSD make
9079 (until 2004) invoked subcommands with sh -e, contra POSIX.
9080 Reported by Kevin Ryde.
9082 2004-05-10 Eric Sunshine <sunshine@sunshineco.com>
9084 * programs.m4 (_AC_PROG_GREP): Fixed bug where PATH argument handed to
9085 _AC_PATH_PROG_FEATURE_CHECK contained leading whitespace (i.e.
9086 " $PATH:/usr/xpg4/bin"). This resulted in bogus tests, such as
9087 `test -f " /usr/bin/grep"', which _always_ failed.
9088 (AC_PROG_SED): Ditto bogus PATH fix.
9089 * autoconf.texi (AC_PROG_GREP): Properly document that this macro
9090 requires that grep correctly supports _multiple_ `-e' options, rather
9091 than stating only that grep should accept `-e'.
9093 2004-05-03 Paul Eggert <eggert@cs.ucla.edu>
9095 Port to C99, which requires that 'exit' be declared.
9097 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Use AC_INCLUDES_DEFAULT
9098 to ensure that stdlib.h is included.
9099 * lib/autoconf/functions.m4 (_AC_LIBOBJ_ALLOCA, AC_FUNC_SETPGRP,
9100 AC_FUNC_STRTOD, AC_FUNC_SETVBUF_REVERSED, AC_FUNC_FORK, _AC_FUNC_FORK,
9101 _AC_FUNC_VFORK, AC_FUNC_WAIT3): Likewise.
9102 * lib/autoconf/specific.m4 (AC_SYS_RESTARTABLE_SYSCALLS): Likewise.
9103 * lib/autoconf/types.m4 (AC_TYPE_GETGROUPS): Likewise.
9104 * lib/autoconf/headers.m4 (AC_HEADER_STDC): Include <stdlib.h>
9105 when using 'exit' in a test; C99 requires that 'exit' be declared.
9107 2004-05-02 Paul Eggert <eggert@cs.ucla.edu>
9109 * doc/autoconf.texi (Particular Programs): AC_PROG_GREP
9110 now prefers 'grep' implementations that accept -e.
9111 (Limitations of Usual Tools): Describe problems of traditional
9112 egrep and fgrep with long input lines, and of traditional grep
9113 with -e.
9114 * lib/autoconf/programs.m4 (AC_PROG_GREP): Check for -e, too.
9115 (_AC_PROG_GREP): Assume 3rd arg is properly quoted for the shell.
9116 All callers changed. Append /usr/xpg4/bin to the PATH, for
9117 Solaris.
9118 (_AC_FEATURE_CHECK_LENGTH): Discard stderr, so we don't bother
9119 the user with complaints about multiple -e options.
9120 * tests/local.at (AC_STATE_SAVE): Use $GREP, not grep.
9121 Define it with AC_PROG_GREP.
9122 * configure.ac (AC_PROG_GREP): Add.
9123 * lib/freeze.mk (GREP): New macro.
9125 2004-05-02 Eric Sunshine <sunshine@sunshineco.com>
9127 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Consult $SHELL as
9128 a possible candidate only after all others fail, rather than
9129 consulting it first. This improves backward compatibility by
9130 better reflecting the way shell selection occurred in previous
9131 versions of Autoconf, and should help to avoid triggering latent
9132 problems in other packages, such as the one in Automake where zsh
9133 is not handled robustly:
9134 http://mail.gnu.org/archive/html/automake/2004-04/msg00095.html
9135 Although it is not Autoconf's responsibility to work around
9136 problems in Automake, it nevertheless makes sense to avoid
9137 introducing unnecessary incompatibilites.
9139 2004-04-22 Albert Chin-A-Young <china@thewrittenword.com>,
9140 Gary V. Vaughan <gary@gnu.org>
9142 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Don't guess
9143 how deeply nested we are when a suitable tool is found, set the
9144 ac_path_TOOL_found flag.
9145 (_AC_PATH_PROG_FEATURE_CHECK): Encapsulate knowledge of how deeply
9146 nested we are in this macro. Break out of all 3 nested loops if
9147 ac_path_TOOL_found is set.
9149 2004-04-21 Gary V. Vaughan <gary@gnu.org>
9151 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Break out
9152 of the _AS_PATH_WALK loop too if GNU flavor is found.
9154 2004-04-21 Alexandre Duret-Lutz <adl@gnu.org>
9156 * doc/autoconf.texi (Limitations of Make): Update documentation
9157 for `$<'. New entry `Long lines', based on a report from Simon
9158 Josefsson. Augment the documentation for SHELL = @SHELL@ with a
9159 paragraph about DJGPP, based on a mail from Richard Dawe.
9161 2004-04-20 Paul Eggert <eggert@twinsun.com>
9163 * tests/c.at (C keywords): Don't assume that GCC supports
9164 "restrict" and "inline", as sufficiently-old GCC versions do not
9165 (also, GCC configured to be in pedantic C89 mode does not).
9166 Problem reported by Sumit Pandya in:
9167 http://mail.gnu.org/archive/html/autoconf/2004-04/msg00092.html
9169 * lib/autoconf/c.m4 (_AC_PROG_CC_G, _AC_PROG_CXX_G): Don't
9170 consider -g to work if it generates warnings when plain compiles
9171 don't. Problem reported by Braden McDaniel in:
9172 http://mail.gnu.org/archive/html/autoconf-patches/2003-07/msg00014.html
9174 * doc/autoconf.texi (Slashes): New section, to document a problem

9185 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Make the
9186 best tool so far counter rely on the tool path variable name to
9187 avoid checks for one tool being affected by the results of running
9188 the length check on a previous tool.
9190 * lib/autoconf/programs.m4 (_AC_PROG_GREP): Take an additional
9191 match expression argument, as different greps have different
9192 regular expression flavours.
9193 (AC_PROG_FGREP): Pass 'FGREP'. fgrep treats all match chars as
9194 literals.
9195 (AC_PROG_EGREP): Pass 'EGREP$'.

9205 * doc/autoconf.texi (Particular Headers, Particular Types, Generic
9206 Types, Specific Compiler Characteristics, System Services,
9207 Obsolete Macros): Use 'long int', 'short int', 'unsigned int'
9208 etc. consistently instead of 'long', 'short', 'unsigned' etc.
9209 * lib/autoconf/c.m4 (AC_LANG_INT_SAVE(C), AC_C_BIGENDIAN): Likewise.
9210 * lib/autoconf/functions.m4 (AC_FUNC_MMAP, AC_FUNC_SELECT_ARGTYPES):

9223 * doc/autoconf.texi (Particular Structures): AC_STRUCT_TIMEZONE
9224 now defines HAVE_DECL_TZNAME if it is declared, when
9225 HAVE_STRUCT_TM_TM_ZONE is not defined.
9226 * lib/autoconf/types.m4 (AC_STRUCT_TIMEZONE): Implement this.
9227 Do not assume atoi. Rely on HAVE_DECL_TZNAME when testing
9228 for HAVE_TZNAME.

9244 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): fix for
9245 quoted -cmdline argument in Portland Group compiler (bug
9246 reported by Jeffrey J. Barteet).

9276 new macros.
9277 * NEWS: Document these changes.
9279 * doc/autoconf.texi: Avoid macros with unbraced arguments,
9280 they make TeX hang up.

9285 * doc/autoconf.texi (Generic Compiler Characteristics): Document it.
9286 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Use long int rather than
9287 int; avoid "a `$1'" since this isn't grammatical if $1 begins with a
9288 vowel.

9308 2004-02-20 Alexandre Duret-Lutz <adl@gnu.org>
9310 * doc/autoconf.texi (Limitations of Usual Tools) <mkdir>: `mkdir -p'

9313 2004-02-18 Paul Eggert <eggert@twinsun.com>
9315 Fix a dependencies problem, stemming from a Autoconf 2.59 build
9316 problem on QNX reported by Stephen Rasku in
9317 <http://mail.gnu.org/archive/html/bug-autoconf/2004-02/msg00066.html>.
9319 * bin/Makefile.am ($(srcdir)/autoconf.in): Depend on
9320 $(m4sh_m4f_dependencies); this removes a FIXME.
9321 * tests/Makefile.am ($(srcdir)/wrapper.in): Likewise.
9322 (MAINTAINERCLEANFILES): Split into pieces,
9323 one per related section. Add $(srcdir)/wrapper.in.
9325 2004-02-09 Paul Eggert <eggert@twinsun.com>
9327 * doc/autoconf.texi (Setting Output Variables): Emphasize that
9328 AC_SUBST provides no portable way to escape literal newlines.
9330 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS): Ignore all
9331 flags of the form -lcrt*.o, not just -lcrt[01].o and -lcrtbegin.o.
9332 Darwin uses -lcrt2.o and there's little point to cataloging all
9333 the system variants. Partial fix reported by Andreas Waechter in:
9334 http://mail.gnu.org/archive/html/autoconf-patches/2004-02/msg00006.html

9350 the behavior of the third argument.
9351 * lib/autoconf/autoupdate.m4 (AU_DEFUN): Describe more
9352 correctly the behavior of the third argument. Document

9358 Eric Sunshine <sunshine@sunshineco.com>
9359 Paul Eggert <eggert@twinsun.com>
9361 * lib/m4sugar/m4sh.m4 (M4SH-SANITIZE): New diversion.

9363 parameter. Expand _AS_SHELL_FN_SPY.
9364 (AS_INIT_WITH_SHELL_FN): Removed.
9365 (_AS_SHELL_FN_SPY): New macro.
9366 (AS_DETECT_REQUIRED, AS_DETECT_SUGGESTED): New
9367 macros.
9368 (AS_SHELL_SANITIZE): Remove loop to find better shell
9369 and documentation for the parameter.

9373 (AS_REQUIRE_SHELL_FN): Require shell functions when
9374 it is used.
9375 (_AS_LINENO_WORKS): Put around braces, we do not
9376 trigger the bash bug anymore.
9377 * lib/autotest/general.m4: Document M4SH-SANITIZE, do not
9378 use AS_INIT_WITH_SHELL_FN.
9379 * bin/autoconf.in, tests/wrapper.in: Regenerated.
9381 2004-01-30 Paolo Bonzini <bonzini@gnu.org>

9387 (AU_DEFUN): Honor the third parameter, create autoupdate
9388 macros with AU_DEFINE.
9389 * lib/autoconf/headers.m4 (AC_USG, AC_MEMORY_H,

9409 * lib/autoconf/general.m4 (_AC_INIT_COPYRIGHT): Add 1992 thorugh
9410 2003 (except 1997) to the list of copyright years. This undoes
9411 the 2003-05-22 change, which removed the older years from the list.
9412 * lib/autoconf/status.m4 (AC_OUTPUT): Update copyright date to 2004.
9414 2004-01-27 Gary V. Vaughan <gary@gnu.org>

9425 _AC_PROG_GREP, and AC_PROG_SED.
9426 (_AC_FEATURE_CHECK_LENGTH): New helper macro for finding the
9427 longest input length accepted by a command.
9428 (AC_PROG_SED): Use it.
9429 * doc/autoconf.texi (Particular Programs): Document the changes.
9430 * NEWS: Updated.
9432 2004-01-27 Paul Eggert <eggert@twinsun.com>

9454 sources.
9456 2004-01-26 Paul Eggert <eggert@twinsun.com>
9458 * doc/autoconf.texi (Default Includes): Include <stdint.h> even if
9459 HAVE_INTTYPES_H is defined. This is needed on Tru64 5.1b with
9460 Compac C V6.5-207 (dtk), which defines uintmax_t in <stdint.h> but
9461 not <inttypes.h>. Problem reported by Tim Mooney in
9462 <http://mail.gnu.org/archive/html/bug-coreutils/2004-01/msg00147.html>.
9463 * lib/autoconf/headers.m4 (_AC_INCLUDES_DEFAULT_REQUIREMENTS):
9464 Likewise.
9466 * lib/autoconf/programs.m4 (AC_PROG_SED): Use diff, not sed;
9467 otherwise "make check" fails because it forbids cmp (I guess
9468 because cmp treats files as binary on DOS-like systems).
9470 * tests/mktests.sh: Update copyright date to 2004, since some tests
9471 have changed in 2004.
9473 2004-01-23 Gary V. Vaughan <gary@gnu.org>

9479 * NEWS: Updated.
9481 2004-01-15 Paul Eggert <eggert@twinsun.com>
9483 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Try -std, not -std1, since
9484 -std1 disables some useful extensions on Tru64. Problem reported
9485 by N. Lichtmaier in
9486 <http://mail.gnu.org/archive/html/autoconf/2004-01/msg00100.html>.
9488 2004-01-14 Paul Eggert <eggert@twinsun.com>
9490 * doc/autoconf.texi (Programming in M4sh): Document that
9491 AS_MKDIR_P succeeds if the destination is a symbolic link
9492 to an existing directory.
9493 (Limitations of Usual Tools): Note that mkdir -p might not
9494 succeed on symlinks to directories.
9496 2004-01-13 Paul Hilfinger <hilfinger@CS.Berkeley.EDU>
9498 * lib/autoconf/autoupdate.m4 (AU_DEFUN): Grammar fix in comment.
9499 * bin/autoheader.in: Grammar fix in message.
9500 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P):
9501 Test for dir before calling mkdir -p. (trivial changes)

9508 2004-01-10 Jim Meyering <jim@meyering.net>
9510 * doc/autoconf.texi (Running the Preprocessor): Correct grammar.
9512 2004-01-09 Paul Eggert <eggert@twinsun.com>
9514 * lib/autoconf/general.m4: Fix bug: AC_CHECK_SIZEOF evokes a warning
9515 with `autoconf -Wall,error'. Bug reported by Eric Blake in:
9516 http://mail.gnu.org/archive/html/autoconf-patches/2004-01/msg00000.html
9517 (_AC_COMPUTE_INT_COMPILE): Invoke _AC_COMPILE_IFELSE, not
9518 AC_COMPILE_IFELSE, since we now assume our caller invokes
9519 AC_LANG_COMPILER_REQUIRE, for symmetry with _AC_COMPUTE_INT_RUN.
9520 (_AC_COMPUTE_INT_RUN): Likewise, for _AC_RUN_IFELSE instead
9521 of AC_RUN_IFELSE; this avoids the warning mentioned above.
9522 (_AC_COMPUTE_INT): Invoke AC_LANG_COMPILER_REQUIRE.
9524 2004-01-07 Paul Eggert <eggert@twinsun.com>
9526 * lib/autoconf/general.m4 (_AC_LIBOBJS_NORMALIZE): Avoid \$ inside
9527 `"'...'"`, as it's confusing (and I suspect it may not work on
9528 some platforms). The code was incorrect anyway, as it assumed
9529 that \$ evaluated to itself in that context. Reported by
9530 Alexandre Duret-Lutz.
9532 2004-01-07 Alexandre Duret-Lutz <adl@gnu.org>
9534 * lib/autom4te.in (Automake-preselections): Preselect AC_LIBTOOL_TAGS
9535 and _LT_AC_TAGCONFIG.
9537 2004-01-06 Paul Eggert <eggert@twinsun.com>
9539 * doc/autoconf.texi (One Macro Call): Fix an incorrect
9540 example, and add more examples. Reported by Eric Sunshine.
9542 2004-01-05 Paul Eggert <eggert@twinsun.com>
9544 * doc/autoconf.texi (Limitations of Usual Tools):
9545 Remove warning against "rm -fr" introduced yesterday; it
9546 was a false alarm.
9548 * bin/Makefile.am (autoconf, autoheader, autom4te, autoreconf,
9549 autoscan, autoupdate, ifnames): Don't use chmod -w.
9550 * lib/Makefile.am (autom4te.cfg): Likewise.
9551 * doc/autoconf.texi (Limitations of Usual Tools): Warn against
9552 "chmod -w".

9555 Paolo Bonzini <bonzini@gnu.org>
9557 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Speed up sed scripts
9558 by doing lineno substitution only on lines containing "$LINENO".
9560 2004-01-04 Paul Eggert <eggert@twinsun.com>
9562 * lib/autoconf/general.m4 (AC_ARG_PROGRAM):
9563 Use "rm -f" to remove conftest.sed, not plain "rm".
9564 Bug reported by David Relson in
9565 <http://mail.gnu.org/archive/html/autoconf/2004-01/msg00011.html>.
9567 * Makefile.am (autom4te-update):
9568 Replace "rm -rf" and "rm -fr" with "rm -f -r", as POSIX requires.
9569 * Makefile.maint (my-distcheck, do-po-update): Likewise.
9570 * doc/autoconf.texi (Guidelines): Likewise.

9580 Warn against "rm -fr".
9582 2004-01-03 Paul Eggert <eggert@twinsun.com>
9584 * doc/autoconf.texi (Limitations of Usual Tools): Mention that cc
9585 -c -o might not work. From a suggestion by Kevin Ryde.
9586 (C Compiler, Generating Sources, Limitations
9587 of Usual Tools, Limitations of Make, Making testsuite Scripts):
9588 Don't put '-o' after non-options, as POSIX doesn't allow this.
9589 Mention that cc's name might be gcc or c89 or whatever.
9591 2004-01-04 Kevin Ryde <user42@zip.com.au>
9593 * doc/autoconf.texi: Add various further index entries.
9595 2003-12-29 Paul Eggert <eggert@twinsun.com>
9597 * bin/autoreconf.in (autoreconf_current_directory):
9598 Fix typo: mkdir without umask arg.
9600 2003-12-27 Alexandre Duret-Lutz <adl@gnu.org>
9602 * doc/autoconf.texi (Limitations of Make) <Automatic rule rewriting>:
9603 Documents OSF1/Tru64 make behavior. Replace `VPATH = ../src' by
9604 `VPATH = ../pkg/src' in examples to make the OSF1/Tru64 make
9605 explanation clearer.
9607 2003-12-24 Andreas Schwab <schwab@suse.de>
9609 * doc/autoconf.texi (Default Includes): Fix misspelling of
9610 AC_INCLUDES_DEFAULT.

9657 (&sizes): New.
9658 Use them.
9659 No longer rely on Gnus to inline the list of signatures: compute
9660 them on the fly.
9662 2003-11-24 Akim Demaille <akim@epita.fr>
9664 * doc/autoconf.texi (Particular Programs): AC_PROG_LEX can

9733 * lib/autoconf/status.m4 (_AC_SRCPATHS): Fix use of AS_SET_CATFILE

9868 * lib/autoconf/functions.m4 (AC_FUNC_FORK): Trivial fix for vfork
9869 cross test.
9871 2003-10-11 Steven G. Johnson <stevenj@alum.mit.edu>
9873 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Use the new official
9874 name for the GNU Fortran 95+ compiler, 'gfortran', not 'g95'.

9886 Problems reported by Eric Sunshine.
9888 2003-10-08 Steven G. Johnson <stevenj@alum.mit.edu>
9890 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Omit quoted
9891 -mGLOB_options_string stuff for Intel ifc, which can cause
9892 _AC_FC_LIBRARY_LDFLAGS to fail. Use (faster) case for

9915 * lib/autoconf/fortran.m4 (_AC_PROG_FC_G): Use language-specific
9916 cache variable instead of $G77 to decide whether to include -O2,
9917 since $G77 is specific to Fortran 77.

9921 * lib/autoconf/fortran.m4 (AC_FC_FREEFORM): Support Absoft "-f

9924 2003-10-03 Steven G. Johnson <stevenj@alum.mit.edu>
9926 * lib/autoconf/fortran.m4 (AC_PROG_FC): Reverse the order of the
9927 arguments so that it can be used with syntax identical to
9928 AC_PROG_F77, and so that we can more easily decide to
9929 remove/deprecate the DIALECT optional argument in the future if it
9930 proves troublesome.
9931 (AC_FC_FREEFORM): Exit 77 upon failure to fix test suite for
9932 non-freeform-supporting compilers. Document freeform flags.
9934 2003-10-03 Akim Demaille <akim@epita.fr>
9936 * configure.ac: Look for emacs, not macs.

9939 2003-10-03 Akim Demaille <akim@epita.fr>
9941 * lib/autom4te.in (Autoreconf-preselections): Trace AC_CONFIG_AUX_DIR.
9942 * bin/autoreconf.in (autoreconf_current_directory): Create the

9946 2003-10-03 Akim Demaille <akim@epita.fr>
9948 * configure.ac: Quotation and formatting changes.

9971 <http://mail.gnu.org/archive/html/bug-autoconf/2003-09/msg00141.html>.

9997 (_AS_MKDIR_P_PREPARE): Change "rm -fr ./-p" to the more-conservative
9998 "test -d ./-p && rmdir ./-p". Suggested by Andreas Schwab in:
9999 http://mail.gnu.org/archive/html/autoconf-patches/2003-09/msg00039.html
10001 2003-09-26 Akim Demaille <akim@epita.fr>
10003 * lib/autoconf/status.m4 (_AC_OUTPUT_COMMANDS): Make sure the
10004 directory for AC_CONFIG_COMMANDS' first argument exists.
10005 This makes valid the invocation of _AC_SRCPATH that follows.
10006 Reported by Eric Sunshine.
10007 * doc/autoconf.texi (Configuration Commands): Adjust.
10009 2003-09-26 Akim Demaille <akim@epita.fr>
10011 * bin/autoscan.in (Autom4te::FileUtils): Use it for find_file.
10012 Reported by Ralf Corsepius.
10014 2003-09-26 Akim Demaille <akim@epita.fr>
10016 * lib/autoconf/general.m4 (AC_HELP_STRING): Don't overquote the
10017 arguments.

10030 The test suite are sometimes assigning timings incorrectly.
10031 Reported by Henk Krus.
10032 Diagnosed by Nicolas Joly.
10034 * lib/autotest/general.m4 (AT_CLEANUP): Rename AT_help as
10035 AT_help_all.
10036 Instead of making AT_help a sequence of assignments to grow
10037 $at_help_all, just make AT_help_all be the growing contents of
10038 $at_help_all, and make a single assignment in...
10039 (AT_INIT): here.
10040 (at_times_skip): Flip the meaning and rename as...
10041 (at_times_p): this.
10042 (AT_INIT): When summarizing the test that ran, remove
10043 $at_times_file after use, and check it is present before trying to
10044 use it.

10052 (ifnames): chmod -w.
10053 * tests/wrapper.as (AUTOCONF, AUTOM4TE, ): Point to tests/
10054 executables, not bin/ executables! Otherwise all the magic needed
10055 to find non installed files is turned off. This caused a failure
10056 of test 40 and 41 that ran aclocal 1.8 which in turn ran autom4te
10057 as found in its environment (sent by tests/autoreconf): pointing
10058 to bin/autom4te that could not find its files.
10059 * tests/mktests.sh: Force the replacement of generated files, for
10060 the sake of "mv" program that are interactive when overwriting a
10061 -w file.

10072 Trivial change to support GCC's configuration procedure.
10073 * lib/autoconf/c.m4 (AC_PROG_CPP_WERROR): New macro.
10074 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): Don't warn
10075 about inconsistency if the preprocessor is set to give errors for
10076 any warning.

10132 From a suggestion by Ian Lance Taylor in
10133 <http://mail.gnu.org/archive/html/autoconf/2003-09/msg00044.html>.
10135 2003-09-05 Paul Eggert <eggert@twinsun.com>
10137 * lib/autoconf/fortran.m4 (AC_FC_FREEFORM): Try -ffree-form too,

10153 * tests/mktests.sh (ac_exclude_list): Add AC_FC_FUNC.
10155 2003-09-02 Steven G. Johnson <stevenj@alum.mit.edu>
10157 Add support for newer Fortran dialects. The F77 interface is
10158 unchanged, and continues to support Fortran 77. New FC macros
10159 correspond to all the old F77 macros, with output variables FC,
10160 FCFLAGS, and FCLIBS. AC_PROG_FC defaults to picking the newest
10161 available dialect, but older dialects can be specified. There are
10162 new macros AC_FC_SRCEXT to set the source extension, and
10163 AC_FC_FREEFORM to accept free-form source files.

10194 'touch -r' have.
10196 2003-08-27 Akim Demaille <akim@epita.fr>
10198 * tests/m4sugar.at (cross_warning): Make sure to enable the
10199 output, so that we can track spurious m4sugar output.
10200 * tests/local.at: Require 2.57.
10201 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): Don't m4_default the arguments that

10258 Output stack traces in warnings.
10260 * lib/m4sugar/m4sugar.m4 (_m4_warn): New.
10261 Replace the former...
10262 (m4_warn): Pass the call stack to _m4_warn.
10263 * bin/autom4te.in: Adjust to output the call stack.
10264 * tests/m4sugar.at (m4@&t@_warn): Adjust.
10266 2003-08-22 Akim Demaille <akim@epita.fr>

10273 * lib/Autom4te/General.pm (&file_name_is_absolute): Remove.
10274 (&verbose): Remove.
10275 (&getopt): Adjust the note and verb channels, depending upon

10279 Use &verb, not &verbose.
10281 2003-08-21 Akim Demaille <akim@epita.fr>
10283 * bin/autoheader.in (&parse_args): Use &parse_warnings and
10284 &parse_WARNINGS.
10285 ($help): Use Autom4te::ChannelDefs::usage.
10286 * bin/autoscan.in: Use Autom4te::ChannelDefs.
10287 * lib/Autom4te/General.pm: Don't export error: you don't own it.
10289 2003-08-21 Akim Demaille <akim@epita.fr>
10291 First stab at preserving warnings between calls to autom4te,
10292 including when the cache is used.
10294 There are still several issues: (i) there are too many runs of m4
10295 (one for include, one for warnings, and some more), (ii) warnings
10296 spreading on several lines are not handled gracefully, (iii) the
10297 code meant to have the call stack display for errors does not work
10298 (its handling should move from m4 to autom4te).
10300 * bin/autom4te.in Autom4te::Channels, Autom4te::ChannelDefs):
10301 Use them.
10302 (@preselect): Add m4_warn.
10303 ($exit_status): Remove, use $exit_code.
10304 ($help): Use Autom4te::ChannelDefs::usage.
10305 (&handle_m4): No longer define the m4_warnings.
10306 At each run, extract and report the warnings.
10307 Always cache the result, including if the exit status is on
10308 failure, since if nothing changes, we should result in the same
10309 failure, hence we can use the cache.
10310 * lib/m4sugar/m4sugar.m4 (m4_warning_ifelse, _m4_warning_ifelse)
10311 (_m4_warning_error_ifelse, __m4_warning_error_ifelse, _m4_warn):
10312 Remove.
10313 (m4_warn): Redefine as a do-nothing: it is its invocation that
10314 matters, as warnings are now reported via traces.
10315 * lib/autoconf/general.m4 (AC_DIAGNOSE): Don't make it a copy of
10316 the contents of m4_warn: make it _call_ m4_warn, so that tracing
10317 the latter reveals calls to the former.
10319 Adjust the tests.
10321 * tests/m4sugar.at (m4@&t@_warn): Use existing warning categories.
10323 2003-08-21 Akim Demaille <akim@epita.fr>
10325 * bin/autoreconf.pm (Autom4te::Channels, Autom4te::ChannelDefs):
10326 Use them.
10328 2003-08-21 Akim Demaille <akim@epita.fr>
10330 * lib/Autom4te/FileUtils.pm (&find_file): Walk the @include in
10331 forward order.
10332 * lib/Autom4te/ChannelDefs.pm: Doc typos.
10333 (&parse_warnings): Accept a list of warning requests.
10334 (&usage): Return a string, not a side effect.
10335 (cross): New warning category.
10337 2003-08-21 Akim Demaille <akim@epita.fr>
10339 * lib/Autom4te/Configure_ac.pm (&find_configure_ac)
10340 (&require_configure_ac): Accept an optional directory argument.
10341 ($configure_ac): Remove.
10342 * lib/Autom4te/General.pm (&find_configure_ac, &canonfile)
10343 (&catfile): Remove.
10344 * bin/autoheader.in, bin/autoreconf.in, bin/autoupdate.in,
10345 * bin/autoscan.in: Adjust.
10347 2003-08-20 Akim Demaille <akim@epita.fr>
10349 * bin/autoheader.in: Remove duplicate 'use Autom4te::FileUtils'.
10350 Reported by Alexandre Duret-Lutz.
10352 2003-08-20 Akim Demaille <akim@epita.fr>
10354 * bin/autoupdate.in, bin/autoheader.in, bin/autoreconf.in,
10355 * bin/autom4te: Adjust.
10356 In particular, be Autoconf tools are really silent when properly
10357 working, bind the verbosity of the 'note' channel to $verbose.
10358 * lib/Autom4te/General.pm (&find_file, &mtime, &update_file)
10359 (&xsystem, &contents): Remove, since they are exported by...
10360 * lib/Autom4te/FileUtils.pm: this.
10361 More perldoc.
10362 * lib/Autom4te/General.pm (&up_to_date_p): Move to...
10363 * lib/Autom4te/FileUtils.pm: here.
10365 2003-08-20 Akim Demaille <akim@epita.fr>
10367 * lib/Autom4te/Channels.pm, lib/Autom4te/ChannelDefs.pm
10368 * lib/Autom4te/Configure_ac.pm, lib/Autom4te/FileUtils.pm: New,
10369 from CVS Automake.
10371 2003-08-20 Akim Demaille <akim@epita.fr>
10373 * Makefile.am (automake_cvsweb, automake_cvsargs, autom4te_files)
10374 (autom4te-update): New.
10375 * Makefile.cfg (update): Bind autom4te-update.
10377 2003-08-19 Derek Price <derek@ximbiot.com>
10379 * lib/autotest/general.m4: Comment various HELP_* diversions.

10383 package specific options and associated help.
10385 2003-08-19 Akim Demaille <akim@epita.fr>
10387 * config/announce-gen, Makefile.cfg: New.

10391 2003-08-19 Alexandre Duret-Lutz <adl@gnu.org>
10393 * lib/autom4te.in (Automake-preselections): Preselect
10394 AC_CONFIG_LIBOBJ_DIR, AC_CONFIG_LINKS, m4_include,

10401 * doc/autoconf.texi (autom4te Invocation): Mention
10402 Autoconf-without-aclocal-m4.
10404 2003-08-18 Derek Price <derek@ximbiot.com>
10406 * doc/autoconf.texi (Writing testsuite.at): Document RUN-IF-FAIL &
10407 RUN-IF-PASS optional arguments.

10418 2003-08-14 Derek Price <derek@ximbiot.com>
10420 * lib/autotestgeneral.m4 (AT_INIT): Reformat test summary line to print
10421 DESCRIPTION rather than FILE and LINE. Shorten result to fit in new,
10422 shorter column three. Add DESCRIPTION to log file content.
10424 2003-08-13 Derek Price <derek@ximbiot.com>
10426 * lib/autotest/general.m4 (AT_INIT): Correct typo in final status
10427 output.

10431 * lib/autotest/general.m4 (AT_CHECK): Use new _AT_CHECK API.
10432 (AT_CHECK_NOESCAPE): Move core functionality to...
10433 (_AT_CHECK): ...this new macro.
10435 2003-08-07 Derek Price <derek@ximbiot.com>
10437 * lib/autotest/general.m4 (AT_CHECK): Move core functionality...
10438 (AT_CHECK_NOESCAPE): ...to this new macro.
10440 2003-07-31 Paul Eggert <eggert@twinsun.com>
10442 * lib/m4sugar/m4sh.m4 (_AS_UNSET_PREPARE): Work around a bug
10443 in Bash 2.01. Problem reported by Brian Gough in
10444 <http://mail.gnu.org/archive/html/bug-autoconf/2003-07/msg00106.html>.

10451 2003-07-07 Paul Eggert <eggert@twinsun.com>
10453 * lib/autoconf/c.m4 (AC_C_INLINE): Wrap the '#define inline ...'
10454 inside '#ifndef __cplusplus'. Problem reported by
10455 Bob Friesenhahn.
10457 2003-07-06 Bill Clarke <llib@computer.org>
10459 * lib/autoconf/functions.m4 (AC_FUNC_MMAP): Cast pointer to
10460 'long', not 'int', for benefit of Sun's recent C++ compilers
10461 (trivial change). See:
10462 http://mail.gnu.org/archive/html/autoconf-patches/2003-07/msg00007.html
10463 (This really should be 'intptr_t', not 'long', but that would
10464 take more work.)
10466 2003-06-25 Akim Demaille <akim@epita.fr>
10468 * lib/Makefile.am (autom4te.cfg): Make it read only.
10469 Depend on Makefile since it contains substitutions.
10470 From Paolo Bonzini.
10471 * lib/autom4te.in (args): Add local.at? for Autotest args.
10472 This change was made on autom4te.cfg which is generated.

10478 From Gareth McCaughan.
10480 2003-06-23 Akim Demaille <akim@epita.fr>
10482 * lib/autotest/general.m4 (AT_INIT): Report a single config.log,
10483 not all of them. This fixes 1. the fact that when testing
10484 Autoconf there are many many config.log, 2. the incorrect use of
10485 top_srcdir to find config.log.
10486 Don't mix the detailed output of failed test with the summary of
10487 failures. Rather, append detailed log afterwards.
10489 2003-06-23 Akim Demaille <akim@epita.fr>
10491 * tests/local.at (AT_CHECK_CONFIGURE): Adjust to the verbose being

10512 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Extend test program to get an
10513 error from OSF 4.0 Compaq cc in its default almost-ANSI mode, thereby
10514 ensuring we add -std1 for full-ANSI.
10516 * doc/autoconf.texi (hdrindex): New macro.
10517 Add index entries for portability of various standard header files.
10519 2003-06-20 Akim Demaille <akim@epita.fr>

10563 * NEWS, doc/autoconf.texi (Particular Functions),
10564 lib/autoconf/functions.m4 (AC_FUNC_MKTIME): Check that mktime
10565 is the inverse of localtime.
10567 2003-05-25 Alexandre Duret-Lutz <adl@gnu.org>
10569 * lib/Autom4te/General.pm (END): Print diagnostics to STDERR.
10570 (handle_exec_errors): New function. Work around $! being
10571 altered by WEXITSTATUS.
10572 (xqx, xsystem): Use handle_exec_errors.
10574 2003-05-23 Alexandre Duret-Lutz <adl@gnu.org>
10576 * lib/Autom4te/General.pm (END): Rewrite exit code processing.
10577 Do not call `_exit()', simply modify `$?'.
10578 (xsystem): Reset $! before running system, and check it afterward.
10579 * tests/tools.at (autoupdating AC_PREREQ): Expect exit status
10580 63 for version mismatches.
10582 2003-05-23 Akim Demaille <akim@epita.fr>
10584 * lib/autoconf/status.m4: Prefer "TAB-SP" to "SP-TAB", because of
10585 Emacs' dangerous whitespace.el behavior (smashing "useless" spaces in
10586 the middle of a line).
10587 * lib/m4sugar/m4sugar.m4: Likewise.
10588 Remove useless spaces in comments.
10590 2003-05-23 Akim Demaille <akim@epita.fr>
10592 * lib/m4sugar/m4sugar.m4 (m4_version_prereq): Failure causes an
10593 exit 63, so that we (or Automake's "missing") can tell the
10594 difference with a plain failure.
10595 * doc/autoconf.texi (Notices): Adjust.
10597 2003-05-23 Akim Demaille <akim@epita.fr>
10599 * Makefile.am, bin/Makefile.am, config/Makefile.am,
10600 * doc/Makefile.am, lib/autoconf/Makefile.am, tests/Makefile.am:
10601 White spaces cleanup.
10603 2003-05-22 Jim Meyering <jim@meyering.net>
10604 Paul Eggert <eggert@twinsun.com>
10606 * lib/autoconf/c.m4 (_AC_PROG_CXX_EXIT_DECLARATION):
10607 Remove `#include <stdlib.h>' from the list; we should never
10608 make confdefs.h include <stdlib.h> or <cstdlib>, because the
10609 resulting namespace pollution would cause other tests to fail.
10610 Configure scripts run with some older versions of g++ and HP's
10611 aCC would fail due to such an #include. Problems reported by
10612 Matthew Mueller in <http://bugs.debian.org/120704> and by
10613 Keith Bostic in
10614 <http://mail.gnu.org/archive/html/autoconf/2003-05/msg00063.html>.
10615 In the test, use the test declaration before including <stdlib.h>,
10616 as that's closer to how it'll be used.
10618 2003-05-23 Akim Demaille <akim@epita.fr>
10620 * doc/autoconf.texi (Header Portability): ucred.h.
10621 From Ian Redfern.
10623 2003-05-22 Paolo Bonzini <bonzini@gnu.org>
10625 Overhaul Autotest's logging: generate separate log files
10626 in testsuite.dir/NNN/testsuite.log, and append them to
10627 testsuite.log instead of re-running the test verbosely.
10629 * lib/autotest/general.m4 (AT_INIT): Use a single redirected
10630 file descriptor, write 0 to at_status_file instead of setting
10631 at_status=0, initialize some new variables (at_status_file,
10632 at_group_log, at_suite_log, at_tee_pipe). Remove the cruft
10633 to rerun the tests, instead append the at_group_log to the
10634 at_suite_log when a test fails.
10635 (AT_SETUP): pipe the test case's output into at_tee_pipe,
10636 with the AS_MESSAGE_LOG_FD redirected to stdout.
10637 (AT_CLEANUP): save the output status in $at_status_file
10638 and restore it, redirect the AS_MESSAGE_LOG_FD back to
10639 its original place.
10640 (AT_CHECK): since tests are run with a redirected stdout,
10641 and used to be re-run in verbose mode, turn some $at_verbose
10642 into echo, and don't redirect the output of testing stdout
10643 and stderr.
10645 * lib/autotest/autoconf.texi (testsuite Scripts): Update
10646 the name of the debugging directory and information about
10647 its contents.
10649 2003-05-22 Paolo Bonzini <bonzini@gnu.org>
10651 * lib/m4sugar/m4sh.m4 (AS_REQUIRE): Actually use the 2nd
10652 parameter.

10675 Suggested by Jim Meyering.
10677 2003-05-22 Akim Demaille <akim@epita.fr>
10679 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Restore smashed
10680 ' \t' as '\t ' so that Emacs' whitespace.el keep it.
10681 Reported by Jim Meyering.
10683 2003-05-22 Akim Demaille <akim@epita.fr>
10685 * doc/autoconf.texi: Replace AC_HELP_STRING AS_HELP_STRING.

10718 2003-05-17 Akim Demaille <akim@epita.fr>
10720 * lib/autoconf/functions.m4: Use the default includes so that
10721 memcmp be declared before being tested.
10722 Reported by Sander Niemeijer.

10743 them uniform, and more robust to Perl special characters.
10744 Reported by Martin Mokrejs.
10746 2003-05-14 Akim Demaille <akim@epita.fr>

10766 2003-05-06 Akim Demaille <akim@epita.fr>
10768 Don't try to be smart with aclocal 1.8+ because (i) aclocal no
10769 longer updates aclocal.m4 if useless, (ii) if a file m4_included
10770 by aclocal.m4 is changed it might require the importing of another
10771 m4 extension file, i.e., aclocal must be run.
10773 * bin/autoreconf.in (&run_aclocal, $aclocal_supports_force): New.
10774 (&parse_args): Use --force with aclocal if required and supported.
10775 (&autoreconf_current_directory): Use &run_aclocal.
10777 2003-05-06 Akim Demaille <akim@epita.fr>

10782 * bin/autom4te.in (&Request::save, &Request::load): Use an IO::File
10783 argument instead of a file name, so that the request file remains
10784 open during the whole autom4te run.
10785 ($icache_file): New.
10786 (&freeze): Lock the $icache_file.
10788 2003-04-29 Derek Price <derek@ximbiot.com>
10790 * lib/autotest/general.m4 (AT_KEYWORDS): Don't use a comma as the
10791 seperator with m4_append_uniq(). It doesn't work.
10792 (AT_CLEANUP): Add `;' to end of at_help_all.
10793 (AT_INIT): Allow --keywords to be specified more than once. When
10794 grepping $at_help_all for keywords, use the field and keyword
10795 seperators to ensure a complete keyword match. Alter at_prev handling
10796 to support the new --keywords behavior.
10798 2003-04-27 Karl Berry <karl@freefriends.org>
10800 * doc/autoconf.texi: Make the dir entries in the autoconf manual
10801 align better with others. I also made some of the individual
10802 entries on one line, for brevity and to make it easier for me to
10803 sort my dir-example file in the Texinfo distribution :).
10805 2003-04-12 Jim Meyering <jim@meyering.net>

10843 New.
10844 Use them.
10845 * doc/Makefile.am (CLEANFILES): Adjust.
10846 (TEXI2DVI): Make it --batch.
10848 2003-03-31 Derek Price <derek@ximbiot.com>
10850 * lib/autotest/general.m4: Revert the checkin from 2003-03-27
10851 which removed the main loop.
10852 Thanks to Akim Demaille.
10854 2003-03-29 Akim Demaille <akim@epita.fr>

10860 2003-03-29 Akim Demaille <akim@epita.fr>
10862 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): The

10869 reading the section "Present But Cannot Be Compiled" when the
10870 header causes problems.
10872 2003-03-28 Akim Demaille <akim@epita.fr>
10874 * tests/torture.at (Configuring subdirectories): Require aclocal
10875 1.4, otherwise the test fails, as it does support configure.ac.
10876 This fixes the "test 40 failed" bug reports.
10878 2003-03-28 Akim Demaille <akim@epita.fr>
10880 * doc/autoconf.texi (C Compiler): `#line' portability.

10908 * lib/autotest/general.m4: s/DEFAULT/DEFAULTS/ since it makes more
10909 sense. Verbosify the diversion definitions comment.
10911 2003-03-26 Derek Price <derek@ximbiot.com>
10913 * lib/autotest/general.m4 (AT_INIT): Remove redundant call to

10945 * doc/autoconf.texi (Limitations of Make): Remove the section
10946 about `$<' in inference rules, it was a bogus interpretation of
10947 an old Automake change. Discuss NetBSD, FreeBSD, OpenBSD, and
10948 Tru64 make in the "target lookup" section.
10949 (Automake): Automake 1.5+ no longer requires special tools to be
10950 present on the developer's host.
10952 2003-02-26 Richard Dawe <rich@phekda.freeserve.co.uk>
10954 * bin/autoheader.in (BEGIN): For DJGPP SHELL may not be set

10968 ${ac_make}.
10970 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS, _AC_OUTPUT_FILES):
10971 When constructing paths with IFS=:, quote the path. If we're
10972 constructing a DOS-style absolute path, we don't want to split it
10973 on the colon.
10975 * tests/atspecific.m4 (AT_CHECK_CONFIGURE): Fix typo
10976 in description.
10978 2003-02-25 Pavel Roskin <proski@gnu.org>

10988 <http://mail.gnu.org/archive/html/autoconf/2003-02/msg00139.html>.
10990 * doc/autoconf.texi (Shell Substitutions): test -n -> test -z,
10991 to fix a mismatch between example and discussion.
10993 2003-02-24 Kevin Ryde <user42@zip.com.au>
10995 * doc/autoconf.texi (Limitations of Builtins): Add notes on printf
10996 format starting with "-".
10998 2003-02-20 Alexandre Duret-Lutz <adl@gnu.org>

11001 is not portable inside Makefile.
11003 2003-02-20 Akim Demaille <akim@epita.fr>
11005 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): When
11006 compiler says yeah, but preproc says nope, compiler is right.
11007 Conversely, prompt the reader to send a bug report to the
11008 maintainers of the package, not of Autoconf.
11010 2003-02-20 Klee Dienes <kdienes@apple.com>
11012 * bin/autoreconf.in (autoreconf_current_directory): Properly
11013 handle an empty aclocal.m4.

11019 From Larry Jones.
11021 2002-12-23 Paul Eggert <eggert@twinsun.com>
11023 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Define $1 to an
11024 innocuous variant befor including <limits.h> or <assert.h>. This
11025 works around a bug reported by Albert Chin: HP-UX 11i
11026 (and earlier versions) have a <limits.h> that declares
11027 gettimeofday and many other functions.
11029 2002-12-03 Paul Eggert <eggert@twinsun.com>
11031 Version 2.57.
11033 * NEWS, configure.ac: Update version.
11035 * doc/fdl.texi: Upgrade to FDL version 1.2.
11037 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Use the function f
11038 nontrivially in main's body, so that f's external declaration is
11039 not optimized away in AIX. This should fix the bug reported by
11040 Martin Frydl in
11041 <http://mail.gnu.org/pipermail/autoconf/2002-November/014508.html>.
11043 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C),
11044 _AC_PROG_PREPROC_WORKS_IFELSE): Use <limits.h> if __STDC__ is
11045 defined, to support freestanding compilers. This should fix the
11046 bug reported by Momchil Velkov in
11047 <http://mail.gnu.org/pipermail/autoconf/2002-November/014490.html>.
11049 * doc/autoconf.texi (Obsolete Macros): Fix typos (insert empty
11050 arg, AC_DEFINE -> AC_DEFINE_UNQUOTED) in documentation for
11051 obsolete AC_CHECK_TYPE. The missing empty arg was reported
11052 by Simon Josefsson in
11053 <http://mail.gnu.org/pipermail/autoconf-patches/2002-December/008830.html>.
11055 * Makefile.maint (www-gnu): New macro.
11056 (standards.texi-url_prefix, make-stds.texi-url_prefix): Use it, as
11057 the location has moved.
11059 2002-12-02 Martin Frydl <martin@systinet.com>
11061 * bin/autom4te.in (at_flatten): rewritten to avoid M4 problem when
11062 \(.*\) match is too long and there is something more to be checked.
11063 <http://mail.gnu.org/pipermail/autoconf/2002-November/014524.html>
11065 2002-11-15 Akim Demaille <akim@epita.fr>
11067 Version 2.56.
11069 * config/install-sh: chmod +x.

11073 * configure.ac (AM_INIT_AUTOMAKE): here.
11074 Require 1.7.1.
11076 2002-11-14 Akim Demaille <akim@epita.fr>

11081 Update from masters.
11083 2002-11-14 Akim Demaille <akim@epita.fr>
11085 * Makefile.maint: Sync with Bison, i.e.:
11086 (po-check): Scan .l and .y files instead of the
11087 .c and the .h files that they generate. This fixes the bug
11088 reported by Tim Van Holder in:
11089 <http://mail.gnu.org/pipermail/bison-patches/2002-November/001352.html>
11090 Look for N_ as well as for _. Try to avoid matching #define for
11091 N_ and _.
11092 From Paul Eggert.
11094 2002-11-14 Akim Demaille <akim@epita.fr>
11096 * doc/autoconf.texi (C Compiler): Compiling several files at once.
11097 From Paul Eggert and Albert Chin-A-Young.
11099 2002-11-14 Akim Demaille <akim@epita.fr>
11101 * doc/autoconf.texi (C Compiler): Solitary backslashes.
11102 From Paul Eggert and Albert Chin-A-Young.
11104 2002-11-14 Kevin Ryde <user42@zip.com.au>
11106 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Initialize f=$1 rather
11107 than assigning in main, to avoid HP cc +O3 optimizing it away.
11109 2002-11-12 Peter Eisentraut <peter_e@gmx.net>
11111 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Add -q
11112 option. Process --recheck after parsing all options. Pass -q
11113 option to configure on --recheck.
11114 (AC_OUTPUT): Pass -q from configure to config.status.
11115 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Strip -q from
11116 arguments to record.
11117 * doc/autoconf.texi (config.status Invocation): Document
11118 config.status -q option.
11120 2002-11-07 Alexandre Duret-Lutz <adl@gnu.org>
11122 * bin/autoscan.in (scan_file): Scan Makefile.am too. Ignore
11123 Makefile.in if Makefile.am exists.
11124 (output): Strip `.am' from Makefiles. Don't
11125 output AC_CONFIG_FILES if no Makefiles were found.

11136 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY): Wrap the `f'
11137 declaration in extern "C" too.
11138 Reported by Roberto Bagnara.
11140 2002-11-06 Akim Demaille <akim@epita.fr>
11142 * tests/torture.at (Configuring subdirectories): Don't use grep

11145 Reported by Ezra Peisach.
11147 2002-11-05 Akim Demaille <akim@epita.fr>
11149 * lib/autoconf/autoheader.m4 (_AH_TEMPLATE_OLD, _AH_VERBATIM_OLD):
11150 Remove.
11151 We _have_ to stop using the old compatibility scheme that tried to
11152 avoid useless backslashes because Libtool 1.4.3 contains a
11153 AC_DEFINE([error_t], [int],
11154 [Define to a type to use for \`error_t' if it is not
11155 otherwise available.])
11156 We _have_ to quote the single quote and backslashes with \. The
11157 old compatibility scheme saw that ` was backslashed, and therefore
11158 did not quote the single quote. Hence before this patch, Autoconf
11159 was not compatible with Libtool.
11161 2002-11-04 Paul Eggert <eggert@twinsun.com>
11163 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Set the following variables,
11164 too: LC_ADDRESS, LC_IDENTIFICATION, LC_MEASUREMENT, LC_MONETARY,
11165 LC_NAME, LC_PAPER, LC_TELEPHONE.

11168 2002-11-04 Akim Demaille <akim@epita.fr>
11170 Version 2.54c.

11173 New.
11174 * config/texinfo.tex: Update.

11179 from...
11180 (&autoreconf): here.
11181 ($help, $make, &parse_args, &autoreconf_current_directory):
11182 Support -m/--make.

11199 (AT_CHECK_ENV): Make sure the `state-ls.before file exists.
11201 2002-10-31 Akim Demaille <akim@epita.fr>
11203 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Use and display
11204 `$(MAKE)' instead of '${MAKE}' to emphasize that we refer to the
11205 Make variable, not a shell variable.
11206 Suggested by Bruno Haible.
11208 2002-10-31 Akim Demaille <akim@epita.fr>
11210 * bin/autom4te.in (load_configuration): Reject #args out of any
11211 language.
11213 2002-10-31 Akim Demaille <akim@epita.fr>

11231 * doc/autoconf.texi (Particular Functions): AC_FUNC_MALLOC and
11232 AC_FUNC_REALLOC check for compatibility with glibc, not POSIX.
11233 Problem reported by Bruno Haible.
11235 2002-10-29 Akim Demaille <akim@epita.fr>
11237 * doc/autoconf.texi (Header Templates): Put also in words what the

11506 Quote for Perl, not sh.
11507 * bin/autoheader.in: When $debug, report the file which is
11508 `do'ne.
11509 * tests/tools.at (autom4te, autoheader): Exercise @bar, not merely
11510 `@', to tickle Perl's lists.
11511 Reported by Carlos Velasco.
11513 2002-10-18 Akim Demaille <akim@epita.fr>
11515 * bin/autom4te.in (handle_m4): Pass --fatal-warning to m4, so that
11516 missing included files _are_ errors.
11517 Thanks to Alexandre Duret-Lutz.
11518 * tests/tools.at (autom4te cache): Adjust.
11519 * tests/atspecific.m4 (AT_CHECK_AUTOM4TE): New.
11520 (AT_CHECK_M4SUGAR): Use it.
11521 * tests/m4sugar.at (m4_warn, m4_require: circular dependencies):
11522 Adjust.
11523 * tests/tools.at (autom4te): Now it does exit 1.
11525 2002-10-17 Akim Demaille <akim@epita.fr>
11527 * lib/autoconf/general.m4 (AC_CACHE_SAVE): Don't use cmp.
11528 Fixes the `AC_ARG_VAR' test failures.
11529 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Don't use cmp.
11530 * lib/freeze.mk (check-forbidden-patterns): New.
11531 * lib/autoconf/Makefile.am, lib/autotest/Makefile.am
11532 * lib/m4sugar/Makefile.am (check-local): Use it to catch `cmp'.
11533 * doc/autoconf.texi (Limitations of Usual Tools): HP-UX' cmp and
11534 /dev/null.
11535 Reported months ago by H. Merijn Brand.
11537 2002-10-17 Akim Demaille <akim@epita.fr>
11539 * tests/tools.at (autoheader): Put randoms `@' to stress Perl.
11541 2002-10-16 Paul Eggert <eggert@twinsun.com>
11543 * Makefile.maint (wget_files): Remove ansi2knr.c.
11544 (ansi2knr.c-url_prefix): Remove.
11546 2002-10-16 Akim Demaille <akim@epita.fr>
11548 Because of caching, some files that no longer exist and are no
11549 longer required can still cause errors.
11550 Reported by Alexandre Duret-Lutz.
11552 * bin/autom4te.in (&parse_args): Do not prepend `--reload-state'
11553 to frozen files in @ARGV, as @ARGV must remain being a list of
11554 files. Rather, at M4 call sites, use this...
11555 (&files_to_options): New function.
11556 (&freeze): Use &error.
11557 (&up_to_date): If a file that was included according to the cache
11558 is no longer there, then the output is out dated.
11559 (&main): Don't even check whether a file is up to date is anyway
11560 --force is given.
11561 * tests/tools.at (autom4te cache): New.
11563 2002-10-16 Akim Demaille <akim@epita.fr>
11565 * bin/autoconf.as: Kill dead options.
11566 * bin/autoupdate.in (&parse_args): Kill old options.
11567 * bin/autoreconf.in (&parse_args): Remove dead options.
11568 Factor some code.
11569 (&autoreconf): Report the directories we enter *and leave*, so
11570 that error messages can be easily located, and use GNU Make
11571 format, so that Emacs' compile mode understands us.
11572 * lib/Autom4te/General.pm (&update_file): Use `verbose' to report
11573 if some file was changed instead of `print'.
11574 * bin/autoheader.in: Suggest AC_DEFINE with 3 args when needed.
11575 (&parse_args): Remove the dead options.
11576 * tests/atspecific.m4 (AT_CHECK_AUTOHEADER): Adjust to the new
11577 autoheader's quiet mode.
11578 (AT_CHECK_AUTOUPDATE): Likewise.
11579 * tests/tools.at (autoupdate): Adjust.
11580 * tests/semantics.at (AC_C_BIGENDIAN): Likewise.
11582 2002-10-11 Akim Demaille <akim@epita.fr>
11584 No longer use CPP to check for the existing of headers: use CC to
11585 check for compilability.
11587 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL)
11588 (AC_CHECK_HEADER, _AC_CHECK_HEADER_OLD): Remove.
11589 (_AC_CHECK_HEADER_NEW): Rename as...
11590 (AC_CHECK_HEADER): this.
11592 * lib/autotest/general.m4 (AT_INIT): Include the failed test
11593 numbers in the Subject suggestion.
11595 2002-10-11 Akim Demaille <akim@epita.fr>
11597 * lib/autoconf/specific.m4 (AC_DECL_SYS_SIGLIST): Obsolete.
11598 Suggest using AC_CHECK_DECLS instead.
11600 2002-10-11 Akim Demaille <akim@epita.fr>
11602 * tests/torture.at (AC_ARG_VAR): Have configure report the value
11603 of `precious'.
11605 2002-10-11 Akim Demaille <akim@epita.fr>
11607 * lib/m4sugar/m4sh.m4 (_AS_PATH_SEPARATOR_PREPARE): Use $$ in the
11608 file name to enable parallel executions.
11609 From Sam Varshavchik.
11611 2002-10-08 Akim Demaille <akim@epita.fr>
11613 * bin/autoreconf.in (&autoreconf): Run autopoint before the first
11614 aclocal invocation, as Gettext macros might not be visible to
11615 aclocal.
11616 Instead of blindly running autopoint, scan configure.ac (not the
11617 traces) for AM_GNU_GETTEXT_VERSION uses, as autopoint does.
11618 Reported by Paul D. Smith.
11620 2002-10-08 Paul Eggert <eggert@twinsun.com>
11622 Work around problems found when POSIXLY_CORRECT=1 is set.
11623 None of this seems to have anything to do with POSIX, really,
11624 but it's how Perl getopt works.
11625 * bin/autom4te.in (parse_args): Configure GetOpt with
11626 "permute", too.
11627 * doc/autoconf.texi (Invoking autom4te):
11628 --warning -> --warnings.
11629 * lib/autom4te.in: --warning -> --warnings.
11631 2002-09-28 Akim Demaille <akim@epita.fr>
11633 * doc/autoconf.texi (autom4te.cache): New section.
11635 2002-09-28 Akim Demaille <akim@epita.fr>

11645 * lib/autoconf/headers.m4, lib/autoconf/libs.m4,
11646 * lib/autoconf/specific.m4, lib/autoconf/types.m4: here.
11648 2002-09-28 Akim Demaille <akim@epita.fr>
11650 * tests/torture.at (Configuring subdirectories): Be robust to
11651 users who use config.site to require for a cache: in this case,
11652 the two last configure runs, using two different sets of
11653 arguments, trigger a legitimate error.
11655 2002-09-28 Akim Demaille <akim@epita.fr>
11657 * tests/m4sh.at (Functions Support, Functions and return Support):
11658 New.

11662 * bin/Makefile.am (ETAGS_SH, ETAGS_PERL): Update: ifnames and
11663 autoheader are Perl programs.
11664 (autoconf, autoheader, autoreconf, autoupdate, ifnames, autoscan)
11665 (autom4te): Specify that the sources are in the $srcdir.
11666 * doc/autoconf.texi (Installation Directory Variables): Adjust.
11668 2002-09-28 Akim Demaille <akim@epita.fr>
11670 * lib/autoscan/autoscan.pre (st_blksize, st_blocks, st_rdev)
11671 (tm_zone): Move their rules to...
11672 * lib/autoconf/types.m4: here, using AN_ macros.
11673 * lib/autoscan/autoscan.pre (AWK, BISON, INSTALL, LEX, LN, MAKE)
11674 (RANLIB, YACC, awk, bison, byacc, flex, gawk, install, lex, ln)
11675 (make, mawk, nawk, ranlib, yacc): Similarly, move to...
11676 * lib/autoconf/programs.m4: here.
11677 * lib/freeze.mk (ETAGS_FOR_M4, ETAGS_FOR_M4SUGAR)

11679 Use it.

11683 * lib/autoconf/autoscan.m4: New file.
11684 * lib/autoconf/autoconf.m4: Include it.
11685 * lib/autoconf/functions.m4: Use AN_FUNCTION for all the functions
11686 that were listed in the original autoscan.list.
11687 * lib/autoconf/headers.m4: Similarly with headers.
11688 * lib/freeze.mk (autoconf_m4f_dependencies): Add autoscan.m4.
11689 (.m4.m4f): Don't pass --prepend-include, since that's done by
11690 tests/autom4te itself.
11691 * lib/autoscan/Makefile.am: Include freeze.mk.
11692 (autoscan.list): New target --this file is no longer a source.
11693 (autoscan.pre): New file.
11695 2002-09-28 Akim Demaille <akim@epita.fr>
11697 * bin/autoscan.in (@kinds): Make them singular.
11698 Adjust all uses.
11699 (&init_tables): When --debug, report the list of rules to ease
11700 tracking changes in autoscan.list.
11701 * lib/autoscan/autoscan.list (function): Strip comments, sort.
11703 2002-09-28 Akim Demaille <akim@epita.fr>
11705 * lib/autoscan/functions, lib/autoscan/headers,
11706 * lib/autoscan/identifiers, lib/autoscan/makevars,
11707 * lib/autoscan/programs: Merge into...
11708 * lib/autoscan/autoscan.list: this.
11709 * bin/autoscan.in (&init_tables): Adjust.
11711 2002-09-28 Akim Demaille <akim@epita.fr>
11713 * lib/autoscan/functions, lib/autoscan/headers,
11714 * lib/autoscan/identifiers, lib/autoscan/makevars,
11715 * lib/autoscan/programs: Make the `kind' explicit, i.e., each
11716 `functions' line is now prefixed with `function:'.
11717 * bin/autoscan.in (&init_tables): Adjust.
11719 2002-09-28 Akim Demaille <akim@epita.fr>
11721 From now on, autoscan files must always map a macro name to a
11722 word: there is no `default' macro for autoscan.
11724 * bin/autoscan.in (&init_tables): Reject entries with no macro at
11725 all.
11726 * lib/autoscan/functions, lib/autoscan/headers: Make the macro
11727 explicit.
11729 2002-09-28 Akim Demaille <akim@epita.fr>
11731 * bin/autoscan.in (%c_keywords): Remove.
11732 (&used): Keep only track of the words we might be interested in.
11733 (&output_kind): It is no longer needed to look for non active
11734 checks.
11736 2002-09-27 Akim Demaille <akim@epita.fr>
11738 * lib/autoconf/functions.m4 (AC_FUNC_MBRTOWC): New, stolen from

11756 (&parse_args): Drop obsolete undocumented options.
11757 (&output_kind): Output warnings.
11758 * lib/autoscan/functions: (dcgettext): Now trigger AM_GNU_GETTEXT.
11759 (getwd): Trigger a warning.
11761 2002-09-26 Akim Demaille <akim@epita.fr>
11763 * bin/autoreconf.in: Clarify that -s is meaningless without -i.
11764 Reported by Ralf Corsepius.
11765 * doc/autoconf.texi (autoreconf Invocation): Likewise.
11767 2002-09-26 Akim Demaille <akim@epita.fr>
11769 Single suffix rules and seperated dependencies are not portable.

11773 Separated Dependencies'.
11774 * bin/Makefile.am (autoconf, autoheader, autoreconf, autoupdate)
11775 (ifnames, autoscan, autom4te): Un-factor into several rules.
11777 2002-09-25 Paul Eggert <eggert@twinsun.com>
11779 * BUGS (Interoperability bugs): New section. Mention libtool
11780 1.4.2, configure.ac, and AC_CONFIG_AUX_DIR interoperability bug.
11782 2002-09-24 Paul Eggert <eggert@twinsun.com>
11784 Fix a portability bug reported by Alexandre Duret-Lutz: Solaris 8
11785 make handles suffix-rules differently from GNU make.
11787 * bin/Makefile.am (SUFFIXES, .in): Remove.
11788 (autoconf autoheader autoreconf autoupdate ifnames autoscan autom4te):

11794 Reported by Ralf Corsepius.
11796 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT): Remove b.out files.
11797 (_AC_COMPILER_EXEEXT_DEFAULT): Adjust to b.out.
11799 2002-09-13 Paul Eggert <eggert@twinsun.com>
11801 * doc/autoconf.texi (Particular Headers): Remove obsolete
11802 reference to `struct timezone' in the description of
11803 AC_HEADER_TIME.
11805 2002-09-13 Akim Demaille <akim@epita.fr>
11807 Version 2.54.

11813 2002-09-13 Akim Demaille <akim@epita.fr>
11815 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Suggest
11816 reading config.log when the compiler is rejected.
11817 Suggested by Guido Draheim.
11819 2002-09-13 Akim Demaille <akim@epita.fr>
11821 * bin/autoreconf.in: Don't use Cwd::chdir, since in its internals
11822 (chdir_init) might hang when stat'ing mounted directories.
11823 Reported by Vance Shipley.
11825 2002-09-12 Akim Demaille <akim@epita.fr>
11827 * bin/autoscan.in (&parse_args): Pass a reference to the lists, not
11828 the lists.
11830 2002-09-12 Akim Demaille <akim@epita.fr>
11832 * doc/autoconf.texi (Defining Symbols): Present two different
11833 prototypes for AC_DEFINE and AC_DEFINE_UNQUOTED to emphasize the
11834 difference between 1 argument calls, and 2-3 argument calls.
11836 2002-09-12 Peter Eisentraut <peter_e@gmx.net>
11838 * doc/autoconf.texi: Review grammar and punctuation.

11842 * doc/autoconf.texi: Fix minor formatting, spelling, and
11843 grammatical typos.
11844 (Defining Symbols): Explain that AC_DEFINE(var) defaults to 1, but
11845 AC_DEFINE(var,,description) does not; and the AC_DEFINE(var) case
11846 is obsolescent.
11848 2002-09-11 Akim Demaille <akim@epita.fr>
11850 * doc/autoconf.texi (Questions): Rename as...
11851 (FAQ): this.

11864 2002-09-09 Akim Demaille <akim@epita.fr>
11866 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Keep the
11867 `duplicates', since the algorithm was too naive and could keep
11868 `--prefix=1 --prefix=2 --prefix=1' as `--prefix=1 --prefix=2', and
11869 keep `--prefix foo --prefix bar' as `--prefix foo bar'.
11870 Reported by Ralf Corsepius.
11871 * tests/torture.at (Configuring subdirectories): Exercise these
11872 cases.
11874 2002-09-09 Akim Demaille <akim@epita.fr>
11876 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Use $srcdir when
11877 looking for a replacement file.
11878 * lib/autoconf/general.m4 (AC_CHECK_DECLS): Check that the
11879 directory is relative.
11880 * doc/autoconf.texi (Generic Functions): Clarify the replacement

11892 * bin/Makefile.am (autoconf, autoheader, autoreconf, autoupdate)
11893 (ifnames, autoscan, autom4te): Since we don't only depend on
11894 configure.ac variables (such as VERSION etc.), but also on prefix
11895 and so forth, depend on Makefile, not configure.ac.
11896 Reported by Alexandre Duret-Lutz.
11897 * doc/autoconf.texi (Installation Directory Variables): Adjust.
11899 2002-09-05 Kevin Ryde <user42@zip.com.au>
11901 * doc/autoconf.texi (Limitations of Make): HP-UX trailing backslashes
11902 doesn't seem to be confined to ia64, just say "some versions".
11904 2002-09-04 Akim Demaille <akim@epita.fr>
11906 * Makefile.am, doc/Makefile.am: Remove pdf targets, handled by
11907 Automake 1.6c.
11908 * Makefile.am (maintainer-clean-local): Remove.
11909 (MAINTAINERCLEANFILES): Remove COPYING.
11911 2002-09-03 Paul Eggert <eggert@twinsun.com>

11915 Brinkmann.
11917 2002-09-03 Akim Demaille <akim@epita.fr>
11919 * configure.ac: Bump to 2.53d.
11920 * Makefile.am (AUTOMAKE_OPTIONS): Require 1.6c, i.e., CVS Automake
11921 as of today, on Automake's team suggestion.
11923 2002-09-03 Akim Demaille <akim@epita.fr>
11925 Version 2.53c.
11927 2002-09-02 Akim Demaille <akim@epita.fr>

11933 2002-09-02 Jim Meyering <meyering@lucent.com>
11935 * doc/autoconf.texi (AC_SYS_POSIX_TERMIOS): Reflect renaming: s/am/ac/,
11936 i.e., change am_cv_sys_posix_termios to ac_cv_sys_posix_termios.
11937 Also, tweak grammar: s/make sure to/be sure to/.
11939 2002-09-02 Paul Eggert <eggert@twinsun.com>
11941 * doc/autoconf.texi (Limitations of Builtins): Explain why logical
11942 directory names are generally preferable to physical names.
11944 2002-09-02 Akim Demaille <akim@epita.fr>
11946 * lib/Autom4te/General.pm (&update_file): s/die/error/.
11947 Reported by Raja R. Harinath.
11948 * bin/autoheader.in, bin/autoreconf.in, bin/autoscan.in,
11949 * bin/autoupdate.in: Use error instead of die.
11951 2002-09-01 Paul Eggert <eggert@twinsun.com>
11953 * tests/mktests.sh (ac_exclude_egrep, au_exclude_egrep): Use
11954 ordinary shell concatenation rather than echo+tr+sed command that
11955 runs afoul of a long-line-related sed bug in Solaris 8.
11957 * bin/autoheader.in (parse_args): --warning -> --warnings.
11959 * bin/autoconf.as: Work even if "ls" outputs "FOO not found" to
11960 stdout, as traditional "ls" does.
11961 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT,
11962 _AC_COMPILER_EXEEXT_O): Likewise.
11963 * doc/autoconf.texi (Limitations of Usual Tools): Add "ls".
11965 * bin/autoconf.as: Add --prepend-include option. This patch was
11966 applied to bin/autoconf.in in the 2002-07-17 patch by Mark D. Roth,
11967 but bin/autoconf.in is generated automatically from bin/autoconf.as.
11969 * bin/autoconf.in, configure: Regenerate.
11971 * doc/autoconf.texi (Special Shell Variables): Mention
11972 ENV, MAIL, MAILPATH, PS1, PS2, PS4. Index PWD.
11974 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Unset ENV, MAIL,
11975 MAILPATH and set PS1, PS2, PS4 to default values, to work
11976 around bug in pre-3.0 UWIN ksh reported by Bruce Lilly.
11977 For LC_ALL etc, first try to set to "C" as POSIX requires and as
11978 the Autoconf documentation specifies; fall back to "unset" only if
11979 this fails. Use a shell for-loop for this rather than an m4 loop,
11980 to shorten the output script.
11982 2002-08-30 Paul Eggert <eggert@twinsun.com>
11984 * doc/autoconf.texi (Special Shell Variables): Mention POSIX
11985 1003.1-2001's requirements for CDPATH. Give a simpler workaround
11986 for the CDPATH problem. Document PWD.
11987 (Limitations of Builtins): Document the problem that "cd $foo" and
11988 "ls $foo" may refer to different directories in shells conforming
11989 to POSIX 1003.1-2001. Use PS1 rather than CDPATH for "unset"
11990 example, since the old example is now out of date.
11992 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Reject FOO if "cd
11993 FOO" and "ls FOO" talk about different directories; this catches
11994 problems when POSIX 1003.1-2001 "cd" fails due to symlink
11995 spaghetti.
11997 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Use AS_UNSET instead
11998 of rolling our own unset.
11999 (_AS_PREPARE): $as_unset CDPATH instead of AS_UNSETting it, since
12000 in practice we needn't worry about CDPATH if unset doesn't work.
12002 * Makefile.in, aclocal.m4, bin/Makefile.in,
12003 config/Makefile.in, doc/Makefile.in, lib/Makefile.in,
12004 lib/Autom4te/Makefile.in, lib/autoconf/Makefile.in,
12005 lib/autoscan/Makefile.in, lib/autotest/Makefile.in,
12006 lib/emacs/Makefile.in, lib/m4sugar/Makefile.in, man/Makefile.in,
12007 tests/Makefile.in: Regenerate with Automake 1.6.3.
12009 * config/config.guess, config/config.sub, config/mkinstalldirs:
12010 Update.
12012 * configure: Regenerate with self.
12014 2002-08-30 Kevin Ryde <user42@zip.com.au>
12016 * doc/autoconf.texi (Limitations of Usual Tools): Notes on "cc"
12017 default output.
12019 2002-08-29 Rainer Orth <ro@TechFak.Uni-Bielefeld.DE>

12022 failure.
12024 2002-08-29 Akim Demaille <akim@epita.fr>
12026 * lib/Autom4te/General.pm (&xqx): New.
12027 (&xsystem): Use WIFEXITED and WEXITSTATUS instead of decoding $? by
12028 hand, which is not portable.
12029 (&error): New.
12030 * bin/autom4te.in: Use them.
12031 Use &error instead of die.
12032 * tests/m4sugar.at (m4_warn, m4_require: circular dependencies):
12033 Adjust.
12035 2002-08-17 Paul Eggert <eggert@twinsun.com>
12037 * lib/autoconf/fortran.m4 (AC_PROG_F77): Remove fc from the
12038 default list of compilers to try, since it was long ago superseded
12039 by the ksh fc builtin. Suggested by Steven G. Johnson.
12041 2002-07-31 Alexandre Duret-Lutz <duret_g@epita.fr>
12043 * doc/autoconf.texi (Invoking autom4te): End the option table,
12044 fixing a bug introduced by the previous patch.
12045 (Limitations of Make): Add a 'target lookup' subentry in the
12046 'VPATH' entry. Rewrite all `make' occurences as `@command{make}'.
12048 2002-07-29 Mark D. Roth <roth@feep.net>
12050 * bin/autom4te.in: Remove --include-envvar and --site-macro-subdir
12051 options and use $AUTOM4TE_PATH.
12052 * doc/autoconf.texi: Remove documentation of autom4te
12053 --include-envvar and --site-macro-subdir options and document
12054 use of $AUTOM4TE_PATH.
12055 * lib/autom4te.in: Remove --include-envvar and --site-macro-subdir
12056 arguments from each language section.
12058 2002-07-29 Paul Eggert <eggert@twinsun.com>
12060 * doc/install.texi: Include copyright symbol in copyright notice.
12062 * Makefile.am (MAKEINFO): Remove; it's a user-specified macro.
12063 Replace with:
12064 (AM_MAKEINFOFLAGS): New macro.
12065 * doc/Makefile.am (MAKEINFO, AM_MAKEINFOFLAGS): Likewise.
12066 * Makefile.am (INSTALL): Use the new macros.
12067 Use -o rather than --output, since "missing" does not grok --output.
12069 2002-07-25 Alexandre Duret-Lutz <duret_g@epita.fr>
12071 * doc/autoconf.texi (Limitations of Make): Escaped newlines in
12072 comments do not always work. Never trust the exit status of
12073 `make -k'.
12075 2002-07-24 Kevin Ryde <user42@zip.com.au>
12077 * doc/autoconf.texi (Limitations of Make, Making testsuite Scripts):
12078 Untabify, since tabs are not enjoyed by texi2dvi and makeinfo.
12080 2002-07-23 Paul Eggert <eggert@twinsun.com>
12082 * lib/m4sugar/m4sh.m4 (_AS_PATH_SEPARATOR_PREPARE):
12083 Use PATH="/nonexistent;.", not PATH=".;.", as FreeBSD ksh2002
12084 apparently treats PATH="nonexistent" as if it contained ".".
12085 Bug reported by Stefan `Sec' Zehl.
12087 2002-07-22 Alexandre Duret-Lutz <duret_g@epita.fr>
12089 * doc/autoconf.texi (Limitations of Make): Mention the special

12142 * lib/Autom4te/General.pm (find_file): Browse the directories in

12204 2002-07-02 Alexandre Duret-Lutz <duret_g@epita.fr>
12206 * bin/autoheader.in, bin/autom4te.in, bin/autoreconf.in,
12207 bin/autoupdate.in, bin/ifnames.in, lib/Autom4te/General.pm,

12209 so that Emacs setups GNU style for perl-mode and cperl-mode.
12211 2002-06-27 Paul Eggert <eggert@twinsun.com>
12213 * config/install-sh: Quote $src. Prefer || to test's -o option,
12214 as per "Limitations of Builtins".
12215 * tests/atspecific.m4 (AT_CHECK_ENV): Likewise, for && vs test -a.
12216 * tests/semantics.at (AC_C_BIGENDIAN): Likewise.
12218 * tests/mktests.sh: Use grep instead of fgrep, as per
12219 "Limitations of Builtins".
12221 2002-06-15 Paul Eggert <eggert@twinsun.com>
12223 * tests/wrapsh.as (AUTOCONF, AUTOHEADER, AUTOM4TE, AUTOM4TE_CFG,
12224 autom4te_perllibdir): Set to top build dir or src dir as appropriate,
12225 so that we consistently test the just-built programs.
12226 * tests/wrappl.as: Likewise.
12228 2002-06-12 Paul Eggert <eggert@twinsun.com>
12230 * bin/autoconf.as (AUTOM4TE): Default to a fully qualified path
12231 name, so that symlinks to 'autoconf' work properly. Bug reported
12232 by Bruno Haible.
12233 * bin/autoheader.in (AUTOM4TE): Likewise.
12234 * bin/autoreconf.in (autoconf, autoheader): Likewise.
12235 * bin/autoscan.in (autom4te): Likewise.
12236 * bin/autoupdate.in (autom4te): Likewise.
12238 * lib/autoconf/functions.m4 (_AC_LIBOBJ_FNMATCH): Also check for
12239 btowc, to fix a portability bug with diffutils-2.8.2/lib/fnmatch.c
12240 on Solaris 2.5.1.
12242 2002-06-11 Andreas Schwab <schwab@suse.de>
12244 * doc/autoconf.texi: Add more dir entries.
12246 2002-06-10 Alexandre Duret-Lutz <duret_g@epita.fr>
12248 * bin/autom4te.in ($cache): Don't define using `$me', the name
12249 of the cache should not depend on the name under which autom4te
12250 was installed.
12252 2002-06-07 Akim Demaille <akim@epita.fr>
12254 * tests/tools.at (autoconf: forbidden tokens, basic)
12255 (autoconf: forbidden tokens, exceptions): Adjust to the change of
12256 words in autom4te.in.
12258 2002-06-07 Peter Eisentraut <peter_e@gmx.net>

12266 rename as...
12267 (AC_REPLACE_FNMATCH): this.
12268 * tests/mktests.sh (exclude_list): Exclude AC_REPLACE_FNMATCH,
12269 AC_FUNC_FNMATCH_GNU.
12271 2002-06-07 Akim Demaille <akim@epita.fr>
12273 * doc/autoconf.texi (Systemology): Point to Tru64 docs, and the
12274 Rosetta Stone for Unix.
12276 2002-06-07 Akim Demaille <akim@epita.fr>
12278 * bin/autom4te.in (warn_forbidden): When rejecting a token,
12279 suggest m4_pattern_allow.
12280 Suggested by Adam J. Richter.
12282 2002-06-07 Akim Demaille <akim@epita.fr>
12284 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Initialize
12285 ac_config_libobj_dir.
12286 (AC_CONFIG_LIBOBJ_DIR): New.
12287 * lib/autoconf/functions.m4 (_AC_FUNC_FNMATCH): Split into...
12288 (_AC_FUNC_FNMATCH_IF, _AC_LIBOBJ_FNMATCH): these.
12289 Use ac_config_libobj_dir to find the replacement files.
12290 (AC_FUNC_FNMATCH, AC_FUNC_FNMATCH_GNU): Split into...
12291 (AC_FUNC_FNMATCH, AC_FUNC_FNMATCH_GNU, AC_REPLACE_FNMATCH)
12292 (AC_REPLACE_FNMATCH_GNU): these.

12295 * tests/mktests.sh (ac_exclude_list): Don't check

12298 2002-06-06 Paul Eggert <eggert@twinsun.com>
12300 * lib/autoconf/status.m4 (_AC_OUTPUT_LINKS): Fall back on cp
12301 if ln doesn't work.
12302 * NEWS: Likewise.
12303 * doc/autoconf.texi (Configuration Links): Likewise.
12304 (Limitations of Usual Tools): Prefer $(LN_S) to ln -s || ln.
12306 2002-06-05 Paul Eggert <eggert@twinsun.com>
12308 * config/config.guess, config/config.sub, config/texinfo.tex:
12309 Update from masters.
12311 2002-05-29 Paul Eggert <eggert@twinsun.com>

12326 * lib/autoconf/programs.m4 (AC_PROG_EGREP, AC_PROG_FGREP): New macros.
12327 * doc/autoconf.texi (Particular Programs): Document them.
12328 (Limitations of Usual Tools): Warn that egrep and fgrep may not exist.
12329 * NEWS: Likewise.
12331 2002-05-27 Paul Eggert <eggert@twinsun.com>
12333 * lib/autoconf/types.m4 (AC_TYPE_MBSTATE_T): New macro.
12334 * NEWS, doc/autoconf.texi (Particular Types): Document it.
12335 * lib/autoconf/functions.m4 (_AC_FUNC_FNMATCH): Require it
12336 instead of AC_MBSTATE_T, which never existed.
12338 2002-05-23 Akim Demaille <akim@epita.fr>
12340 * doc/autoconf.texi (Hosts and Cross-Compilation): Specify the
12341 version of Autoconf that is discussed.
12343 2002-05-22 Paul Eggert <eggert@twinsun.com>
12345 * lib/autoconf/fortran.m4 (AC_PROG_F77): Remove cf77 and cft77
12346 from the default list of compilers to try. Suggested by
12347 Kate Hedstrom.
12348 * NEWS: Document the above.
12349 * doc/autoconf.texi (Fortran 77 Compiler): Don't suggest cf77.
12351 2002-05-17 Paul Eggert <eggert@twinsun.com>
12353 * lib/autoconf/types.m4 (AC_CHECK_MEMBER): Work correctly even if
12354 the member is itself an aggregate. Bug reported by Sergey Poznyakoff.
12355 This improves on an earlier suggestion by H. Peter Anvin.
12357 2002-05-16 Paul Eggert <eggert@twinsun.com>
12359 AC_FUNC_FNMATCH now tests only for POSIX compatibility.
12360 AC_FUNC_FNMATCH_GNU also tests for GNU extensions.
12361 Both macros now accept an optional source-dir arg.
12362 New macro AC_GNU_SOURCE to define _GNU_SOURCE.
12364 * NEWS: Document this.
12365 * doc/autoconf.texi (Particular Functions, UNIX Variants): Likewise.
12367 * lib/autoconf/functions.m4 (_AC_FUNC_FNMATCH): New macro.
12368 (AC_FUNC_FNMATCH): Use it. Test only for POSIX conformance,
12369 not for GNU extensions; this undoes part of the 2000-11-03 change,
12370 reverting to 2.13-compatible behavior.
12371 Add new optional argument DIR.
12372 (AC_FUNC_FNMATCH_GNU): New macro.
12374 * lib/autoconf/specific.m4 (AC_GNU_SOURCE): New macro.
12376 2002-05-08 Paul Eggert <eggert@twinsun.com>
12378 * lib/autoconf/headers.m4 (AC_HEADER_TIOCGWINSZ):
12379 Don't require AC_SYS_POSIX_TERMIOS. The test is unnecessary,
12380 and it causes a 'test' syntax error if it fails.
12381 Bug reported by Stephen Gildea.
12383 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
12384 If prototypes are supported, use them to check this at compile-time,
12385 instead of trying to check it at run-time. If we must do a run-time
12386 check, assume that setvbuf is standard when cross-compiling, as
12387 nonstandard setvbuf occurs only on ancient and unlikely hosts.
12388 Bug reported by Paul D. Smith.
12390 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Add optional
12391 argument specifying location of getloadavg.c. This removes a
12392 FIXME. This idea was taken from Jim Meyering's implementation in
12393 textutils.
12394 * doc/autoconf.texi (Particular Functions): Document this.
12395 Also, mention HAVE_NLIST_H rather than NLIST_STRUCT, since
12396 that's what the code does; this fixes a bug reported by
12397 Paul D. Smith.
12399 2002-05-03 Akim Demaille <akim@epita.fr>
12401 * bin/autoreconf.in (autoreconf): Rewrite to use Gettext's
12402 autopoint instead of gettextize.
12403 ($uses_alocal): Rename as...
12404 ($uses_aclocal): this.
12405 * doc/autoconf.texi (autoreconf Invocation): Adjust.
12406 Suggested by Bruno Haible.
12408 2002-05-03 Akim Demaille <akim@epita.fr>
12410 * lib/m4sugar/m4sugar.m4 (m4_map_sep): New.
12412 2002-04-29 Paul Eggert <eggert@twinsun.com>
12414 * bin/autoreconf.in (autoreconf): Don't age aclocal.m4's input
12415 files to be 1 second older; just set them to be the same time.
12416 Also, sleep 1 second after the first aclocal, to work around
12417 problems with sub-second time stamps on the input files.
12419 2002-04-29 Thien-Thi Nguyen <ttn@gnu.org>
12421 * doc/autoconf.texi: Mention "set -e -x" lossage
12422 under node "Limitations of Builtins".
12424 2002-04-29 Akim Demaille <akim@epita.fr>
12426 * doc/install.texi: Better wording for setting variables when
12427 running configure.
12428 From Christian Cornelssen.
12430 2002-04-29 Akim Demaille <akim@epita.fr>
12432 * tests/m4sh.at (LINENO): If testsuite itself is rewritten because
12433 of lack of $LINENO support, then the test will compare the $LINENO
12434 in testsuite vs. the lineno in the test file. This is wrong, of
12435 course.
12436 Be sure to protect it.
12437 Reported by Patrick Welche.
12439 2002-04-25 Akim Demaille <akim@epita.fr>
12441 * doc/autoconf.texi (Obsolete Macros): Typo.
12442 Reported by Vladimir Volovich.
12444 2002-04-25 Akim Demaille <akim@epita.fr>
12446 * bin/autoreconf.in (autoreconf): Don't let aclocal.m4 be older
12447 than some of the input files, hence, on the second run of aclocal,
12448 if some of its input are younger, make them older.
12449 Suggested by Paul Eggert.
12451 2002-04-25 Akim Demaille <akim@epita.fr>
12453 * doc/autoconf.texi (Limitations of Usual Tools): sed and `!'.
12454 Thanks to Paul Eggert.
12456 2002-04-25 Akim Demaille <akim@epita.fr>
12458 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Let ac_subst_files
12459 and ac_subst_vars be sh variables containing the list of
12460 AC_SUBST_FILES'ed and AC_SUBST'ed identifiers. Output them in the
12461 DEFAULT diversion.
12462 (_AC_INIT_PREPARE): Use them to log them.
12463 (_AC_SUBST, _AC_SUBST_SED_PROGRAM): Remove.
12464 (AC_SUBST, AC_SUBST_FILE): Instead of buliding the
12465 _AC_SUBST_SED_PROGRAM, store the list of output files/variables in
12466 _AC_SUBST_FILES and _AC_SUBST_VARS.
12467 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Adjust.
12469 2002-04-24 Akim Demaille <akim@epita.fr>
12471 * bin/autoreconf.in (autoreconf): Run automake after autoconf and
12472 autoheader, so that automake does not complain about a missing
12473 config.h.in that was to be created.
12475 2002-04-23 Akim Demaille <akim@epita.fr>
12477 * bin/autoheader.in (parse_args): --warning takes an argument.

12493 2002-04-22 Akim Demaille <akim@epita.fr>
12495 * doc/autoconf.texi (Pretty Help Strings): Remove a spurious
12496 comma.
12497 Reported by Gregory Giannoni.
12499 2002-04-22 Akim Demaille <akim@epita.fr>
12501 * tests/m4sh.at (LINENO): Skip the test if LINENO cannot be unset.
12502 Fixes false failures on Darwin.

12527 Minor spelling and grammar fixes.
12529 * doc/autoconf.texi: Follow the outline suggested in the GNU
12530 Sample Texts sections of the Texinfo 4.2 manual. Most
12531 importantly, this makes sure that the copyright notices appear in
12532 all output formats. You probably need Texinfo 4.2 to generate
12533 the manual now.
12535 Fix some bugs when using "$@" when there might be zero positional
12536 arguments in cases where this matters.

12557 that is not portable to Zsh.
12559 2002-04-19 Alexandre Duret-Lutz <duret_g@epita.fr>
12561 * bin/autoupdate.in (handle_autoconf_macros): Honor AU_DEFUNs

12570 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Install the Zsh
12571 workaround for ${1+"$@"}.
12572 * doc/autoconf.texi (Shell Substitutions): Explain it.
12573 From Oliver Kiddle and Peter Stephenson.
12575 Have M4sh perform minimal shell sanitizing.
12577 * lib/m4sugar/m4sh.at (AS_SHELL_SANITIZE): Split the `_AS_PREPARE_*'
12578 part into...
12579 (_AS_PREPARE): this new macro.
12580 (AS_PREPARE): New.
12581 (AS_INIT): Invoke AS_SHELL_SANITIZE.
12582 * tests/m4sh.at (AT_DATA_LINENO): Use _AS_PREPARE.
12584 Adjust Autoconf and Autotest.
12586 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Don't invoke
12587 AS_SHELL_SANITIZE, AS_INIT did it, but invoke AS_PREPARE.
12588 * lib/autotest/general.m4 (AT_INIT): Likewise.
12589 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
12590 Invoke _AS_PREPARE (not AS_PREPARE) in addition to
12591 AS_SHELL_SANITIZE.
12593 Use this M4sh to generate Autoconf's shell scripts.
12595 * tests/wrapsh.as: New, precursor of wrapsh.in.
12596 * tests/Makefile.am: Include lib/freeze.mk to get the dependencies
12597 on Autotest and M4sh.
12598 ($(TESTSUITE)): Use $(autotest_m4f_dependencies).
12599 (wrapsh.in): New target.
12600 * bin/autoconf.as: New, precursor of autoconf.in.
12601 (autoconf.in): New target.
12603 2002-04-09 Alexandre Duret-Lutz <duret_g@epita.fr>

12606 with indented comments in rules.
12608 2002-04-09 Andreas Schwab <schwab@suse.de>
12610 * lib/autoconf/status.m4 (_AC_SRCPATHS): Handle empty
12611 ac_top_builddir when setting ac_abs_top_builddir.
12613 2002-04-06 Kevin Ryde <user42@zip.com.au>
12615 * doc/autoconf.texi (Systemology): Add link to Unix V7 online docs.
12616 (Portable Shell): Cross reference to Systemology.
12618 2002-04-05 Akim Demaille <akim@epita.fr>
12620 * bin/autoreconf.in (autoreconf): Be sure to accumulate the
12621 directories when descending in a SUBDIRS.
12622 Reported by Ezra Peisach.
12624 2002-04-04 Andreas Schwab <schwab@suse.de>
12626 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Only simplify if path
12627 contains no literal separators.
12629 2002-04-03 Akim Demaille <akim@epita.fr>
12631 * lib/autoconf/status.m4 (_AC_CONFIG_FILE, _AC_CONFIG_HEADER)
12632 (_AC_CONFIG_COMMAND, _AC_CONFIG_LINK): New.
12633 Use dnl, not the KILL diversion.
12634 Extracted from...
12635 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_COMMANDS)
12636 (AC_CONFIG_LINKS): here.
12637 Adjust.
12638 Don't use the KILL diversion, as it kills spurious output, which
12639 results in failures being hidden.
12640 Use m4_defn where appropriate.
12641 (AC_CONFIG_IF_MEMBER): Kill the real bug: a spurious parenthesis
12642 after the second argument.
12643 Use m4_defn.
12644 * lib/autom4te.in (Autoconf, Autotest, M4sh): Don't pass --warning
12645 syntax, as it is provided by M4sugar.
12646 * tests/torture.at (Multiple AC_CONFIG_FILES): New.
12648 2002-04-03 Andreas Schwab <schwab@suse.de>
12650 * lib/m4sugar/m4sugar.m4 (m4_bmatch): Make sure m4_bregexp is not
12651 expanded if $# <= 2.
12653 * bin/autoreconf.in (autoreconf): Run automake after rerunning
12654 aclocal.

12661 (_AC_COMPILER_EXEEXT_DEFAULT, _AC_COMPILER_EXEEXT_O)
12662 (_AC_COMPILER_OBJEXT): Use them.
12663 Fixes Debian #138666.
12665 2002-04-02 Peter Eisentraut <peter_e@gmx.net>
12667 Integrate AC_PROG_CC_STDC into AC_PROG_CC.
12669 * lib/autoconf/c.m4 (AC_PROG_CC_STDC): Rename to _AC_PROG_CC_STDC.
12670 AU_DEFUN old name. Use _AC_COMPILE_IFELSE.
12671 (AC_PROG_CC): Call _AC_PROG_CC_STDC.
12672 (AC_C_INLINE): Do not require AC_PROG_CC_STDC.
12673 (AC_C_CONST): Same.
12674 (AC_C_INLINE): Same.
12675 (AC_C_PROTOTYPES): Same. Require AC_PROG_CC instead.
12676 * doc/autoconf.texi, NEWS: Document.
12677 * tests/mktests.sh (au_exclude_list): Add AC_PROG_CC_STDC and
12678 AC_C_CROSS.
12680 2002-04-02 Akim Demaille <akim@epita.fr>

12683 _AS_MKDIR_P_PREPARE.
12685 2002-03-28 Kevin Ryde <user42@zip.com.au>
12687 * lib/autoconf/c.m4 (AC_C_INLINE): Test with a typedef return value,
12688 to avoid versions of HP C which don't allow that.
12690 2002-03-27 Paul Eggert <eggert@twinsun.com>
12692 * lib/m4sugar/m4sh.m4 (_AS_BASENAME_PREPARE): New macro.
12693 (AS_SHELL_SANITIZE): Invoke it.
12694 (AS_BASENAME): AS_REQUIRE it, and use $as_basename.
12696 2002-03-26 Akim Demaille <akim@epita.fr>
12698 * doc/autoconf.texi (Portable Shell): Add pointers to FAQs.
12700 2002-03-26 Akim Demaille <akim@epita.fr>
12702 * doc/autoconf.texi (Introduction): The GNATS base moved.
12704 2002-03-25 Paul Eggert <eggert@twinsun.com>
12706 * tests/m4sh.at: Don't rely on "PATH=test:$PATH test-1" working
12707 as POSIX requires, as it doesn't work with Zsh.
12708 * doc/autoconf.texi (Assignments): Document the problem.
12710 2002-03-25 Alexandre Duret-Lutz <duret_g@epita.fr>
12712 * doc/autoconf.texi (Limitations of Make): Mention more issue
12713 about VPATH, overriding of macros in sub-makes, and handling of
12714 SHELL.
12716 2002-03-21 Paul Eggert <eggert@twinsun.com>
12718 * doc/autoconf.texi (Here-Documents): Mention Solaris 8 dtksh
12719 problem with here-document buffer boundaries.
12721 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Unset ENV and BASH_ENV
12722 when reinvoking the shell, to work around problems with installers
12723 who put strange things like "cd" commands in their environments.
12725 2002-03-19 Akim Demaille <akim@epita.fr>
12727 * tests/semantics.at (AC_C_BIGENDIAN): s/unknow/unknown/.
12728 From Aaron Ucko.
12730 2002-03-19 Akim Demaille <akim@epita.fr>
12732 * bin/autoscan.in (scan_file): Specify the location in `&used'
12733 invocations.
12734 From Nicolas Joly.
12736 2002-03-19 Akim Demaille <akim@epita.fr>
12738 * doc/autoconf.texi: Adjust @code/@command, @xref/@ref usage.
12739 From Nishio Futoshi.
12741 2002-03-19 Akim Demaille <akim@epita.fr>
12743 * lib/m4sugar/m4sugar.m4 (m4_define_default, m4_fst, m4_map): New.
12745 2002-03-18 Paul Eggert <eggert@twinsun.com>
12747 * doc/autoconf.texi (Programming in M4sh): Add AS_MKDIR_P.
12748 (Limitations of Usual Tools): Add mkdir section.
12750 * lib/m4sugar/m4sh.m4 (_AS_MKDIR_P_PREPARE): New macro.
12751 (AS_MKDIR_P): Require it. Use mkdir -p if available, falling
12752 back on AS_DIRNAME to compute prefixes otherwise; this is
12753 roughly what mkinstalldirs does. That way, we need not have
12754 our own filename disassembler. The old disassembler did not
12755 work with Solaris 8 dtksh, which is ksh Version M-12/28/93d.
12757 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP):
12758 Create at_test_all by a series of assignments,
12759 not by a single assignment of a long string. The latter causes ksh
12760 version 11/16/88g to silently misbehave on OpenServer 5.0.6a,
12761 presumably because of a buffer overrun.
12763 2002-03-14 Paul Eggert <eggert@twinsun.com>
12765 * lib/autotest/general.m4 (at_times_skip):
12766 Renamed from at_times. Now a boolean.
12767 ksh93 Version M-12/28/93d doesn't like 'x=times; $x'; it
12768 says 'times: not found'.
12770 2002-03-14 Akim Demaille <akim@epita.fr>
12772 * bin/autoreconf.in (&study_gettextize): New.
12773 (&autoreconf): Handle newest gettextize.
12774 Rerun aclocal if needed.
12775 Suggested by Andreas Schwab.
12777 2002-03-13 Akim Demaille <akim@epita.fr>
12779 * doc/autoconf.texi (Special Shell Variables): More about IFS.

12784 Add information about stdint.h and inttypes.h from Paul Eggert.
12786 2002-03-13 Akim Demaille <akim@epita.fr>
12788 * doc/autoconf.texi (Limitations of Usual Tools): Some about `cp
12789 -p'.
12790 From Bob Proulx.
12792 2002-03-12 Akim Demaille <akim@epita.fr>
12794 * lib/m4sugar/m4sh.m4 (AS_BASENAME_EXPR): AS_REQUIRE, not
12795 m4_require.
12797 2002-03-11 Andreas Schwab <schwab@suse.de>
12799 * configure.ac: Explicitly check for EMACS since AM_PATH_LISPDIR
12800 does not do it if --with-lispdir is given.
12802 2002-03-08 Akim Demaille <akim@epita.fr>
12804 Version 2.53.
12806 2002-03-08 Akim Demaille <akim@epita.fr>
12808 * doc/autoconf.texi (Subdirectories): Clarify that the
12809 subdirectory should exist.
12811 2002-03-08 Akim Demaille <akim@epita.fr>
12813 * Makefile.am (AUTOMAKE_OPTIONS): 1.6.
12815 2002-03-08 Akim Demaille <akim@epita.fr>
12817 * bin/autom4te.in (&handle_m4): Do not foreach with `$_' as it
12818 aliases the actual variables, and modifications of the former
12819 affect the latter.
12821 2002-03-08 Akim Demaille <akim@epita.fr>
12823 * bin/autom4te.in (&handle_m4): Protect us from corrupted file
12824 because of C-c: have m4 output in tmp files, then mv them.
12826 2002-03-08 Akim Demaille <akim@epita.fr>
12828 * bin/autoconf.in, bin/autoheader.in, bin/autom4te.in,

12836 2002-03-05 Akim Demaille <akim@epita.fr>
12838 * doc/autoconf.texi (Specifying Names): Clarification suggested by
12839 Kevin Ryde.
12841 2002-03-05 Akim Demaille <akim@epita.fr>
12843 Version 2.52i.
12845 2002-03-04 Akim Demaille <akim@epita.fr>
12847 * doc/autoconf.texi (AC_LIBOBJ vs. LIBOBJS): New.
12848 * lib/autoconf/general.m4 (AC_INIT): More informative error
12849 message for LIBOBJ.
12851 2002-03-04 Akim Demaille <akim@epita.fr>
12853 * lib/freeze.mk ($(build_libdir)/m4sugar/version.m4): New, for
12854 parallel builds.
12856 2002-03-04 Akim Demaille <akim@epita.fr>
12858 * doc/autoconf.texi (Transforming Names): Equality between target
12859 and host is irrelevant.
12860 (Specifying Names, Canonicalizing): Remove all references to the
12861 backward compatibility hooks. Rather, collect them all into...
12862 (Hosts and Cross-Compilation): this new section.
12863 * doc/install.texi (System Type): Ditto.
12864 * lib/autoconf/general.m4 (AC_CANONICAL_HOST): Explicitly state
12865 that `--host' implies cross-compilation.
12867 2002-03-04 Akim Demaille <akim@epita.fr>
12869 * doc/autoconf.texi (Evaluation Macros): New.
12870 * lib/m4sugar/m4sugar.m4 (m4_lquote): Remove, it is totally
12871 useless.
12872 (_m4_foreach): Define the variant with immediate evaluation so
12873 that it contains exactly the items, not an expression which
12874 evaluation is the current item.
12875 (m4_re_string, m4_re_word): Don't over quote them.
12877 2002-03-04 Akim Demaille <akim@epita.fr>
12879 Instead of having stacking `shift's evaluated at the end, let
12880 `foreach' loops immediately evaluate them.
12882 * lib/m4sugar/m4sugar.m4 (m4_quote, m4_dquote): Use $@ rather than
12883 $*. This is the n-th time I change my mind, but hopefully this is
12884 the last...
12885 (m4_lquote): New.
12886 (m4_text_wrap): Use m4_foreach, which is finally correct _and_
12887 efficient.
12888 (m4_foreach_quoted, m4_car_quoted, _m4_foreach_quoted): Remove, as
12889 it was only a hack for m4_text_wrap.
12890 (m4_car2): Remove, replaced by...
12891 (m4_cdr): New.
12892 (_m4_foreach): Adjust.
12893 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Adjust, and use
12894 m4_bpatsubst for clarification.
12896 2002-03-04 Akim Demaille <akim@epita.fr>
12898 * doc/autoconf.texi (Changequote is Evil): New.

12902 * doc/autoconf.texi (Portable Shell): Mention 32-byte #! length limit

12925 From Akinori Musha.
12927 2002-02-13 Alexandre Duret-Lutz <duret_g@epita.fr>
12929 * lib/Autom4te/XFile.pm (getline, getlines): New functions,
12930 translate \r\n to \n.
12932 2002-02-07 Akim Demaille <akim@epita.fr>
12934 Version 2.52h.
12936 2002-02-07 Akim Demaille <akim@epita.fr>

12943 2002-02-07 Akim Demaille <akim@epita.fr>
12945 Fix Autoconf PR/207:
12946 AC_PREFIX_PROGRAM fails with dashed program names
12948 * lib/autoconf/general.m4 (AC_PREFIX_PROGRAM): Just use a fresh
12949 variable when looking for the prefix program.
12950 Now it also works for shell variables.
12952 2002-02-07 Akim Demaille <akim@epita.fr>
12954 * doc/autoconf.texi (Limitations of Builtins): More about
12955 case/esac.
12957 2002-02-06 Akim Demaille <akim@epita.fr>
12959 * lib/autoconf/status.m4 (_AC_OUTPUT_COMMANDS): Don't output empty
12960 case/esac, some shells don't support it.
12961 Reported by Zack Weinberg.
12962 * tests/torture.at (AC_CONFIG_COMMANDS with empty commands): New.
12964 2002-02-06 Akim Demaille <akim@epita.fr>
12966 * lib/autotest/general.m4 (AT_INIT): When handling --keywords, be
12967 sure not to introduce newlines in at_groups.
12968 * lib/autotest/Makefile.am (autotest.m4f): Typo.
12970 2002-02-06 Akim Demaille <akim@epita.fr>
12972 * tests/torture.at (Configuring subdirectories): Skip if aclocal
12973 is not available.
12975 2002-02-05 Paul Eggert <eggert@twinsun.com>
12977 * doc/autoconf.texi (Specific Compiler Characteristics):
12978 Describe HP-UX cc bug workaround more accurately.
12979 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Cast to long,
12980 not unsigned long.
12981 * tests/semantics.at (AC_CHECK_SIZEOF): Check non-GCC
12982 cross-compilers, too. This undoes some of the most recent change
12983 to this file.
12985 2002-02-05 Akim Demaille <akim@epita.fr>
12987 * tests/Makefile.am (check_SCRIPTS): Use it, instead of WRAPPERS,
12988 to make sure they are up to date when `check' is run.
12990 2002-02-05 Akim Demaille <akim@epita.fr>
12992 * doc/autoconf.texi (Making testsuite Scripts): Document
12993 package.m4.
12995 2002-02-05 Akim Demaille <akim@epita.fr>
12997 * lib/freeze.mk: New.
12999 2002-02-05 Akim Demaille <akim@epita.fr>
13001 Implement `autom4te --freeze'.
13003 * bin/autom4te.in (&freeze): New.
13004 * lib/autoconf/autoconf.m4, lib/autotest/general.m4,
13005 * lib/m4sugar/m4sh.m4: Don't include files given by autom4te.
13007 2002-02-05 Akim Demaille <akim@epita.fr>
13009 * bin/autom4te.in (&parse_args): Implement `frozen files are
13010 optional are the sum of the previous files on the command line'.
13011 Also, pass `--reload-state=' on them, so...
13012 (handle_m4): don't.
13013 * lib/autom4te.in (Autotest, Autoconf): Rely on M4sh.
13014 (M4sh): Rely on M4sugar.
13015 (Autotest, M4sh, M4sugar): Use frozen files.
13017 2002-01-31 Akim Demaille <akim@epita.fr>
13019 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Accept $4.
13020 * doc/autoconf.texi (Initializing configure): Adjust.
13022 2002-01-30 Akim Demaille <akim@epita.fr>
13024 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Map non
13025 alphanumeric to `-' instead of `_'.
13027 2002-01-30 Akim Demaille <akim@epita.fr>
13029 * tests/semantics.at (AC_CHECK_SIZEOF): Split into two tests: one
13030 for plain code, the other for cross-compilation code. The latter
13031 is now run with GCC only.
13032 * doc/autoconf.texi (Compilers and Preprocessors): New.
13034 2002-01-30 Akim Demaille <akim@epita.fr>
13036 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Support pre-defined
13037 values.
13038 * doc/autoconf.texi (Initializing configure): Explain how to
13039 change AC_INIT default values.
13041 2002-01-29 Akim Demaille <akim@epita.fr>
13043 * tests/torture.at (Configuring subdirectories): Use configure.in,
13044 so that aclocal 1.4 works.
13045 Reported by Alexandre Duret-Lutz and Larry Schmitt.
13047 2002-01-28 Akim Demaille <akim@epita.fr>
13049 * doc/autoconf.texi (Writing testsuite.at): AT_CLEANUP no longer
13050 needs an argument.
13052 2002-01-28 Akim Demaille <akim@epita.fr>
13054 * lib/autotest/general.m4 (AT_INIT): Don't be ridiculous: adjust
13055 AUTOTEST_PATH *after* it was set.
13056 Don't put `.' in the PATH: the user should be precise and `./' if
13057 needed. In addition, given that the test suite does some `cd', if
13058 `.' is in the path, the `tested programs' sections will report
13059 programs found in the test suite's directory, while during the
13060 tests (performed in their own directory), these programs are no
13061 longer visible. In other words, the results is confusing and
13062 useless.
13063 * tests/m4sh.at: Adjust: don't rely on `.' being in the PATH.
13065 2002-01-24 Akim Demaille <akim@epita.fr>
13067 Version 2.52g.
13069 2002-01-24 Akim Demaille <akim@epita.fr>
13071 * bin/autoheader.in, bin/autoconf.in, bin/autoscan.in,
13072 * doc/autoconf.texi: Finally add Akim as an author.
13074 2002-01-24 Akim Demaille <akim@epita.fr>
13076 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Use PATH_SEPARATOR.
13077 (_AS_PATH_SEPARATOR_PREPARE): Don't expect $SHELL to be
13078 Bourne. Use /bin/sh.
13079 From Andreas Buening.
13081 2002-01-24 Akim Demaille <akim@epita.fr>
13083 * config/config.guess, config/config.sub, config/texinfo.tex:
13084 Update from masters.
13086 2002-01-24 Akim Demaille <akim@epita.fr>

13090 * config/init.m4, config/install-sh.m4, config/lispdir.m4,
13091 * config/missing.m4, config/sanity.m4, config/select.m4,
13092 * config/strip.m4: Remove, to ease sync'ing with any version of
13093 Automake.
13095 2002-01-24 Akim Demaille <akim@epita.fr>
13097 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS)
13098 (_AC_INIT_PREPARE): Support -n as --no-create, as documented.
13099 Reported by Geir Ove Myhr.
13101 2002-01-21 Akim Demaille <akim@epita.fr>
13103 * lib/autoconf/functions.m4 (AC_FUNC_MMAP): #Undef malloc.
13105 2002-01-21 Akim Demaille <akim@epita.fr>
13107 * lib/Autom4te/General.pm (getopt): Use a more GNUish error
13108 message on invalid options.
13109 * bin/autom4te.in (parse_args): Don't use
13110 Autoconf::General::getopt with non valid options.
13112 2002-01-17 Jim Meyering <meyering@lucent.com>
13114 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Initialize
13115 $ac_cv_exeext so we don't use an old, invalid, cached value.
13117 2002-01-11 Akim Demaille <akim@epita.fr>
13119 * lib/autoconf/functions.m4 (AC_FUNC_STRNLEN): New, from Jim
13120 Meyering.
13121 * doc/autoconf.texi (Function Portability): Document the strnlen
13122 limitation.
13123 (Particular Functions): Document AC_FUNC_STRNLEN.

13126 2002-01-06 Akim Demaille <akim@epita.fr>
13128 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Don't create
13129 package.m4, since is really depends upon configure.ac, not
13130 configure.
13131 * doc/autoconf.texi (testsuite Scripts): Adjust.
13132 * tests/Makefile.am (package.m4): New.
13133 EXTRA_DIST it since its a source.
13135 2002-01-06 Akim Demaille <akim@epita.fr>
13137 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Move the AC_SUBST
13138 of PACKAGE_NAME, PACKAGE_TARNAME, PACKAGE_VERSION, PACKAGE_STRING,
13139 and PACKAGE_BUGREPORT from here...
13140 (_AC_INIT_DEFAULTS): to here, since it is unrelated to the
13141 arguments.
13142 (_AC_INIT_PREPARE): AC_DEFINE these symbols.
13143 * lib/autotest/general.m4: Use AT_PACKAGE_*, not PACKAGE_*.
13144 (AT_INIT): No longer catch `^PACKAGE_(BUGREPORT|STRING)$'.
13145 * tests/tools.at (autoheader): Adjust.
13146 * tests/atspecific.m4 (AT_CHECK_DEFINES): Adjust.
13148 2002-01-06 Akim Demaille <akim@epita.fr>

13152 2002-01-03 Akim Demaille <akim@epita.fr>
13154 * doc/autoconf.texi (Output): Improved wording regarding use of
13155 AC_OUTPUT.
13156 From Olly Betts.
13158 2001-12-18 Kevin Ryde <user42@zip.com.au>
13160 * doc/autoconf.texi (Function Portability): Add notes on sscanf
13161 sometimes needing writable input.
13163 2001-12-17 Jim Meyering <meyering@lucent.com>
13165 * doc/autoconf.texi (New Macros): Tweak wording.
13167 2001-12-14 Akim Demaille <akim@epita.fr>
13169 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): We cleaning up the
13170 trailing files, don't apply `-rf' to files which might not be
13171 created by configure (core, core.*, and *.core), but just `rm -f'.
13172 Suggested by Jonathan Kamens.
13174 2001-12-14 Aaron M. Ucko <amu@alum.mit.edu>
13176 * lib/autoconf/general.m4: Avoid duplicates in `$ac_configure_args'.
13178 2001-12-14 Akim Demaille <akim@epita.fr>
13180 * Makefile.am (MAINTAINERCLEANFILES): Remove configure.
13182 2001-12-13 Peter Eisentraut <peter_e@gmx.net>
13184 * lib/autoconf/status.m4 (_AC_SRCPATHS): Rename buildpath to
13185 abs_builddir, top_buildpath to abs_top_builddir, srcpath to
13186 abs_srcdir, top_srcpath to abs_top_srcdir.
13187 (_AC_OUTPUT_FILES): Adjust.
13188 * NEWS, doc/autoconf.texi, lib/autoconf/autotest.m4,
13189 * tests/atspecific.m4, tests/autoreconf.in, tests/tools.at,
13190 * tests/wrappl.in, tests/wrapsh.in: Adjust.
13192 2001-12-12 Steven G. Johnson <stevenj@alum.mit.edu>
13194 * lib/autoconf/fortran.m4 (_AC_PROG_F77_V_OUTPUT): Fix failed
13195 C/Fortran linking on HP/UX, by extracting the Fortran library
13196 search path from the LPATH line in the $F77 -v output.
13198 2001-12-12 Kevin Ryde <user42@zip.com.au>
13200 * doc/autoconf.texi (File Descriptors): Use a clearer layout for the
13201 forbidden file descriptors table.
13203 2001-11-26 Akim Demaille <akim@epita.fr>
13205 * bin/autoscan.in (%c_keywords): Build it at top level.
13206 Map to 1 in order to simplify its uses.
13208 2001-11-26 Akim Demaille <akim@epita.fr>
13210 * bin/autoscan.in (&scan_c_file, &scan_sh_file, &scan_makefile):
13211 Remove $filepath, useless.
13212 (&scan_makefile): Don't remove the $(FOO), ${FOO} and @FOO@
13213 variables, they are really part of the tokens.
13214 Split the input line on spaces and then look for tokens.
13215 Now autoscan ceases to ask for AC_PROG_LEX for the package Bison
13216 because of `lex$U.$(OBJEXT)'.
13217 (&scan_files): Use "@list" instead of join.
13218 * doc/Makefile.am (CLEANFILES): Add *.fns.
13220 2001-11-26 Akim Demaille <akim@epita.fr>
13222 * tests/autoreconf.in, tests/autom4te.in, tests/autoupdate.in:
13223 Remove, replaced by...
13224 * tests/wrappl.in: Be common for all the Perl executables.
13225 In particular autoscan and autoheader want -I.
13226 * configure.ac: Adjust.
13227 * lib/autoscan/headers: errno.h is portable.
13229 2001-11-26 Akim Demaille <akim@epita.fr>
13231 * bin/autoscan.in (used): New.
13232 Use it.
13234 2001-11-26 Akim Demaille <akim@epita.fr>
13236 * bin/autoscan.in (&scan_c_file): Better parsing of CPP
13237 directives.
13238 (&scan_sh_file): Remove a duplicate pattern.
13239 (&check_configure_ac): Use long options.
13240 * lib/autoscan/headers (alloca.h): Check with AC_FUNC_ALLOCA.
13242 2001-11-26 Akim Demaille <akim@epita.fr>
13244 * bin/autoscan.in (scan_c_file): Fix the handling of C comments.
13245 Before, having a line containing the opening of a multi line
13246 comment made the whole line be ignored.
13248 2001-11-26 Akim Demaille <akim@epita.fr>
13250 * doc/autoconf.texi (Using an Autotest Test Suite): New.
13251 (testsuite Scripts): Be one of its subsection.
13252 (Autotest Logs): New.
13254 2001-11-26 Akim Demaille <akim@epita.fr>
13256 Test groups are now run two directories deeper.
13258 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Replace srcdir,
13259 top_srcdir and top_builddir with at_srcdir, at_top_srcdir and
13260 at_top_builddir.
13261 * lib/autotest/general.m4 (AT_INIT): Compute srcdir,
13262 top_srcdir, builddir and top_builddir.
13263 Use `at_*dir' relatively to the directory containing the
13264 suite, use `*dir' when relatively to the current group dir.
13266 2001-11-25 Joseph S. Myers <jsm28@cam.ac.uk>
13268 * doc/autoconf.texi, TODO, lib/autoconf/fortran.m4,
13269 lib/autoconf/functions.m4, lib/autoconf/headers.m4,
13270 tests/atgeneral.m4, tests/tools.at, tests/atspecific.m4: Fix
13271 spelling errors.
13273 2001-11-22 Alexandre Duret-Lutz <duret_g@epita.fr>
13275 * doc/autoconf.texi (Using System Type): Add an example of `case
13276 $host' usage so people quit using `case $target' everywhere.
13278 2001-11-22 Akim Demaille <akim@epita.fr>
13280 * doc/autoconf.texi (Installation Directory Variables): Englishoes
13281 spotted by Jim Meyering.
13283 2001-11-16 Paul Eggert <eggert@twinsun.com>
13285 This patch implements a `long double' suggestion by Oliver Kiddle.
13287 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C)): Make the array
13288 static, to catch errors if the value isn't known at compile-time
13289 and the compiler supports dynamic arrays. Change its name from
13290 `_array_' to `test_array' to avoid potential name clashes.
13291 (AC_C_LONG_DOUBLE): Make it a compile-time test, not a run-time
13292 test. Do not define HAVE_LONG_DOUBLE if `long double' is no
13293 better than double. Catch a bug in GCC 2.95.2 x86.
13294 * doc/autoconf.texi (C Compiler): Document the above.
13295 * NEWS: Likewise.
13297 2001-11-13 Akim Demaille <akim@epita.fr>
13299 * tests/m4sh.at (LINENO): Protect from autom4te's substitution by
13300 hand.
13301 * tests/tools.at: Don't protect dnl, AT_DATA_M4SH does.
13303 2001-11-13 Akim Demaille <akim@epita.fr>
13305 * lib/autotest/general.m4 (AT_INIT): After having run the test
13306 group, go back to the initial directory, not to at_suite_dir.
13308 2001-11-13 Akim Demaille <akim@epita.fr>
13310 * tests/atspecific.m4 (AT_DATA_M4SUGAR, AT_DATA_M4SH)
13311 (AT_DATA_AUTOCONF): Also protect @&t@ from autom4te.
13312 (AT_CHECK_AUTOCONF, AT_CHECK_AUTOHEADER): Pass no --include
13313 option.
13314 (AT_CHECK_CONFIGURE): Use absolute paths.
13315 (_AT_CHECK_AC_MACRO): Create aclocal.m4 with AC_STATE_SAVE in it.
13316 The problem is still the old one: there is no means in M4 (that I
13317 know about) to create a defining macro, because there is no means
13318 to create `$1' etc., therefore, the defining macro ``swallows''
13319 all the arguments meant to the defined macro.
13321 2001-11-13 Akim Demaille <akim@epita.fr>
13323 * tests/atspecific.m4 (AT_DATA_AUTOCONF): New.
13324 (AT_CONFIGURE_AC): Output the definition of AC_STATE_SAVE in
13325 configure.ac.
13326 * tests/aclocal.m4: Remove, as it is no longer used.
13328 2001-11-13 Akim Demaille <akim@epita.fr>
13330 * lib/autotest/general.m4: Change `tests?' into `groups?' in
13331 variable names when referring to a single test group, or to
13332 `suite' when referring to the whole test suite.
13333 `at_last_test' is removed: m4 compute at_format itself.
13334 (at_stdout, at_stder1, at_stderr): New variables.
13335 (AT_CHECK): Use them.
13337 2001-11-13 Akim Demaille <akim@epita.fr>
13339 * lib/autotest/general.m4 (AT_INIT): Be sure to put `.', relative,
13340 in PATH.
13341 Create `testsuite.dir/003/run' instead of `testsuite.003'.
13342 Do it as soon as a test fails, don't wait till the end of the test
13343 suite.
13344 Don't remove $as_me.[0-9]*, since these files no longer exist.
13346 2001-11-13 Akim Demaille <akim@epita.fr>
13348 * tests/tools.at: Use absolute paths, since we are no longer run
13349 in place.
13351 2001-11-13 Akim Demaille <akim@epita.fr>
13353 Now that tests are running in their own private dir, there is no
13354 need to list the files to remove at the end of tests groups.
13356 * lib/autotest/general.m4 (_AT_CLEANUP_FILE, AT_CLEANUP_FILES):
13357 (AT_data_files, at_data_files): Remove.
13358 (AT_CLEANUP, AT_DATA): Simplify.
13359 (AT_INIT): Adjust.
13360 Remove the group dir if !debug && !failed.
13361 * tests/atspecific.m4: Adjust.
13363 2001-11-13 Akim Demaille <akim@epita.fr>
13365 Start a new layout for Autotest: `testsuite' creates
13366 `testsuite.dir' in which the at-check-line etc. files are to be
13367 found, and `testsuite.dir/003' where the test group 3 is run.
13369 * lib/autotest/general.m4 (AT_INIT): at_tests_dir,
13370 at_check_line_file, at_format, at_test_normalized, at_group_dir
13371 are new variables.
13372 Create the directories.
13373 Use absolute paths for at- files.
13374 (AT_CHECK): Adjust.
13376 2001-11-11 Michael Matz <matz@kde.org>
13378 * m4sugar.m4 (_m4_foreach): Make it linear instead quadratic.
13379 (m4_car2): New.
13380 (m4_car): Properly quote arguments.
13382 2001-11-13 Akim Demaille <akim@epita.fr>
13384 * tests/aclocal.m4 (AC_STATE_SAVE): s/LIBOBJS/LIB@&t@OBJS/ to cope
13385 with stricter rules on LIBOBJS.
13387 2001-11-12 Paul Eggert <eggert@twinsun.com>
13389 * lib/autoconf/c.m4 (AC_C_PROTOTYPES): Define __PROTOTYPES too.
13390 * doc/autoconf.texi (C Compiler): AC_C_PROTOTYPES now defines
13391 __PROTOTYPES too.
13393 2001-11-12 Akim Demaille <akim@epita.fr>
13395 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT): Use AC_CHECK_FUNCS.
13397 2001-11-12 Akim Demaille <akim@epita.fr>
13399 * lib/autoconf/c.m4, lib/autoconf/fortran.m4,
13400 * lib/autoconf/functions.m4, lib/autoconf/general.m4,
13401 * lib/autoconf/headers.m4, lib/autoconf/libs.m4,
13402 * lib/autoconf/programs.m4, lib/autoconf/specific.m4,
13403 * lib/autoconf/types.m4: When invoking AC_DEFINE and friends,
13404 specify to what the macro should be defined (typically to 1).
13406 2001-11-12 Akim Demaille <akim@epita.fr>
13408 * lib/autoconf/functions.m4 (AC_FUNC_STRTOD): AC_SUBST POW_LIB.
13409 From Jim Meyering.
13411 2001-11-12 Akim Demaille <akim@epita.fr>
13413 * lib/autoconf/programs.m4 (_AC_PROG_LEX_YYTEXT_DECL): Use
13414 AC_TRY_EVAL to run $LEX, not AC_TRY_COMMAND. This validates the
13415 definition used by Automake where LEX is +/- "${missing} lex" and
13416 `missing' itself contains variables.
13418 2001-11-12 Akim Demaille <akim@epita.fr>
13420 * lib/autotest/general.m4 (AT_INIT): Push KILL at the end.
13421 Now that M4sh pushes BODY, the comments were output at the end of
13422 the test suites.
13424 2001-11-08 Akim Demaille <akim@epita.fr>
13426 * bin/autoreconf.in (&autoreconf): Run aclocal before tracing, so
13427 that we can trace macros from aclocal.m4.
13428 Trace AC_PROG_LIBTOOL, not AM_PROG_LIBTOOL, since the latter is
13429 obsoleted, and redirect to the former anyway.
13430 Reported by Ralf Corsepius.
13432 2001-11-08 Akim Demaille <akim@epita.fr>
13434 * bin/autoreconf.in (&autoreconf): AC_CONFIG_SUBIDRS are to be
13435 processed only if present.
13436 * tests/torture.at (Configuring subdirectories): Use autoreconf
13437 instead of successive calls to autoconf.
13438 Add a nonexistent subdirectory to exercise the patch above.
13439 Reported by Ralf Corsepius.
13441 2001-11-08 Kevin Ryde <user42@zip.com.au>
13443 * doc/autoconf.texi (Limitations of Usual Tools): Note HP-UX cc
13444 doesn't accept .S files.

13452 (handle_output): Use it.
13453 Read m4_pattern_forbid with messages.
13455 2001-11-05 Akim Demaille <akim@epita.fr>
13457 * bin/autom4te.in (--normalize): Remove.
13458 * lib/autom4te.in: Adjust.
13460 2001-11-05 Akim Demaille <akim@epita.fr>
13462 * tests/Makefile.am (testsuite): Rename this target as...
13463 ($(TESTSUITE)): this.
13464 From Nicolas Joly.
13466 2001-11-05 Alexandre Duret-Lutz <duret_g@epita.fr>
13468 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): When removing
13469 the --prefix option, also remove it's argument.
13471 2001-11-05 Akim Demaille <akim@epita.fr>
13473 * doc/autoconf.texi (testsuite Invocation): Update.
13474 (Writing testsuite.at): Update.

13482 * lib/Autom4te/General.pm: (&catfile, &canonfile)
13483 (&file_name_is_absolute): New, wrappers around routines from
13484 File::Spec.
13485 Use and export them.
13486 (&find_configure_ac): Optionally take a directory where to look at.
13487 * bin/autoreconf.in (&parse_args): Trim the configure.ac part of
13488 the arguments.
13489 Default @ARGV to `.', not find_configure_ac.
13490 (&autoreconf): Argument is a directory.
13491 Trace AC_CONFIG_SUBDIRS and schedule the subdirs for autoreconf'ing.
13492 * doc/autoconf.texi (autoreconf Invocation): Update.
13494 2001-11-03 Akim Demaille <akim@epita.fr>
13496 * lib/Autom4te/General.pm (@export_vars, @export_subs)
13497 (@export_forward_subs): New.
13498 Add basename, dirname, and fileparse.
13499 (@EXPORT): Adjust.
13500 * bin/autoreconf.in (&autoreconf): Fix call to fileparse.
13501 Don't look for aclocal flags if we already know aclocal is not
13502 used.
13503 Move aclocal.m4t only if it exists.
13504 Reported by Ezra Peisach.
13506 2001-11-03 Akim Demaille <akim@epita.fr>
13508 * bin/autoreconf.in (&parse_args): Work only on the configure.ac
13509 passed on command line, defaulting to ./configure.ac if present.
13510 (&maybe_autoreconf, File::Find): Remove, unused.
13511 (&autoreconf): If autoconf is not used, don't try to trace.
13513 2001-11-02 Akim Demaille <akim@epita.fr>
13515 * configure.ac: Bump to 2.52g.
13517 2001-11-02 Akim Demaille <akim@epita.fr>
13519 Version 2.52f.
13521 2001-11-02 Akim Demaille <akim@epita.fr>
13523 * config/config.guess, config/config.sub, doc/standards.texi:
13524 * config/lispdir.m4: Update from masters.
13525 * configure.ac: Bump to 2.52f.
13527 2001-11-02 Akim Demaille <akim@epita.fr>
13529 * bin/autoreconf.in (&autoreconf): Set `$aclocal_flags' to ''.
13530 Don't run aclocal when aclocal.m4 is not from aclocal.
13531 From Ezra Peisach.
13532 Don't run libtoolize and gettextize if --install is not given.
13534 2001-11-01 Paul Eggert <eggert@twinsun.com>
13536 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): _AS_CR_PREPARE needs to
13537 be invoked before _AS_LINENO_PREPARE.
13538 (_AS_LINENO_PREPARE): Use as_cr_digits and as_cr_alnum rather
13539 than character ranges.
13541 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Fix NLS before
13542 invoking AS_BASENAME. Set the locale variables to 'C' if
13543 possible, as POSIX requires this to get the traditional
13544 behavior.
13545 * doc/autoconf.texi (Special Shell Variables): Describe the above.
13547 2001-10-31 Paul Eggert <eggert@twinsun.com>
13549 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): Do not surround body
13550 with {}, as that triggers a bug in Bash 2.05.
13552 (_AS_LINENO_PREPARE): Use Sed rather than
13553 Awk. Fix the sed prepass to work even if there are multiple
13554 instances of $LINENO on the same line. Do not substitute for
13555 other variables like $LINENOT. Do not check file dates; such a
13556 check is unreliable on sufficiently fast machines, and removing
13557 the check makes the code simpler and more reliable. Check for
13558 output and chmod failures.
13560 * doc/autoconf.texi (Special Shell Variables): Document
13561 the above.
13563 2001-10-31 Akim Demaille <akim@epita.fr>
13565 * tests/Makefile.am (atconfig): Remove this target, Automake
13566 handles it now.
13568 2001-10-31 Akim Demaille <akim@epita.fr>
13570 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Do not
13571 AC_CONFIG_FILES(atlocal) as it means a file atlocal.in *must* be
13572 provided, while it is optional.
13573 * configure.ac: Adjust.
13575 2001-10-26 Paul Eggert <eggert@twinsun.com>
13577 * NEWS, README, configure.ac, lib/Autom4te/General.pm,
13578 lib/Autom4te/Struct.pm:
13579 Require Perl 5.005_03 instead of just 5.005, as some tests fail
13580 with 5.005_02.
13582 * doc/autoconf.texi (Special Shell Variables): Document some
13583 more LINENO gotchas, particularly with respect to the Awk+Sed hack.
13585 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): New macro.
13586 (_AS_LINENO_PREPARE): Use it instead of shell eval, since
13587 eval $LINENO is not portable in practice.
13589 2001-10-24 Akim Demaille <akim@epita.fr>
13591 * lib/Autom4te/General.pm (backname): New.
13593 2001-10-24 Akim Demaille <akim@epita.fr>
13595 * m4/: Remove, merged into...
13596 * config/: here.
13598 2001-10-23 Tim Van Holder <tim.van.holder@pandora.be>
13600 * doc/autoconf.texi (Shellology): Mention the problems with bash
13601 2.05's use of ANSI quoting in its `set' builtin.
13603 2001-10-22 Paul Eggert <eggert@twinsun.com>
13605 * lib/autoconf/functions.m4 (AC_FUNC_STRERROR_R):
13606 Rename ac_cv_func_strerror_r_works to ac_cv_func_strerror_r_char_p,
13607 and rename HAVE_WORKING_STRERROR_R to STRERROR_R_CHAR_P, since
13608 POSIX decided to standardize on the int flavor of strerror_r.
13609 Always do char* test, as there's no reason not to.
13610 Assign to a char* var, to catch strerror_r that returns int*.
13612 * doc/autoconf.texi (Particular Functions):
13613 Document the above changes. Also, document the fact that
13614 AC_FUNC_STRERROR_R defines HAVE_DECL_STRERROR_R.
13616 * NEWS: Mention HAVE_WORKING_STRERROR_R -> STRERROR_R_CHAR_P.
13618 2001-10-20 Akim Demaille <akim@epita.fr>
13620 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): The name of
13621 the executable was missing from the log.

13625 * lib/Autom4te/General.pm (&update_file): If destination is
13626 unchanged, remove the source.
13627 (&up_to_date_p): Don't be verbose, be debug.
13628 * bin/autoreconf.in: No longer support --m4dir.
13629 (&autoreconf): Display the full path of the configure.ac we are
13630 studying.
13631 Trace it only once.
13632 Be sure to honor --force with gettextize.
13633 Always run aclocal.
13634 * doc/autoconf.texi: Adjust.
13636 2001-10-20 Akim Demaille <akim@epita.fr>
13638 * bin/autoheader.in ($localdir, $m4, $SIMPLE_BACKUP_SUFFIX):
13639 Remove, dead.
13640 * bin/autoreconf.in (&autoreconf): Do not run gettextize when
13641 `intl' is already present, as it refuses unless --force.
13642 (&parse_args): Use -I, --include instead of the old Autoconf
13643 options.
13644 ($localdir, $autoconf_dir): Remove.
13645 (@include): New.
13646 (&maybe_autoreconf): New, to preserve $_ for File::Find.
13648 2001-10-19 Jens Petersen <petersen@redhat.com>

13656 file in @configure_input@.
13657 Don't mention `automatically' in addition to `generated'.
13658 * tests/torture.at (#define header templates): Adjust.
13660 2001-10-19 Akim Demaille <akim@epita.fr>
13662 * lib/emacs/autoconf-mode.el, lib/emacs/autotest-mode.el: In a
13663 comment, explain how to install automatic mode selection.
13664 From Russ Allbery.
13666 2001-10-19 Ezra Peisach <epeisach@zif.mit.edu>
13668 * bin/autoreconf.in (autoreconf): Display the path to the
13669 configure.ac being studied.
13671 2001-10-18 Paul Eggert <eggert@twinsun.com>
13673 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Cast sizeof to unsigned
13674 long, to work around a bug in the HP C compiler version HP92453-01
13675 B.11.11.23709.GP.
13677 * lib/m4sugar/m4sh.m4 (AS_DIRNAME): Use 'dirname' if that works.
13678 (AS_BASENAME_EXPR): New macro.
13679 (AS_BASENAME_SED): Do not assume GNU sed semantics.
13680 (AS_BASENAME): Use 'basename' if that works; then try 'expr';
13681 and fall back on 'sed' only if the other two fail. This makes
13682 AS_BASENAME act more like AS_DIRNAME.
13683 (as_me): Shell-quote the argument of AS_BASENAME, in case $0
13684 contains white space.
13685 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR):
13686 Use AS_DIRNAME, since I think it's now DOS-friendly.
13687 * tests/m4sh.at (DIRNAME_TEST): New arg $3.
13688 Allow "dirname //FOO" to return either / or //, as POSIX allows
13689 either behavior.

13693 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Recognize
13694 `a_out.exe' for OpenVMS 7.1, DEC C 5.5 compiler, via GNV.
13695 From Eric Sharkey.

13699 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N_PREPARE): m4_defun, not
13700 m4_define, since...

13739 bother with $force since...

13794 2001-10-08 Akim Demaille <akim@epita.fr>
13796 Use `add-log-current-defun-function' for ChangeLog creation.
13797 Suggested by Tom Tromey.

13817 * tests/base.at: Adjust the tests to use AS_INIT.
13818 * tests/tools.at (AT_DATA_FORBIDDEN): New.

13824 * doc/autoconf.texi (config.status Invocation):
13825 CONFIG_SHELL defaults to a shell that supports LINENO if available.
13827 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): If the current

13829 empty, and if we can find a shell that does support LINENO,
13830 then set CONFIG_SHELL to that shell and then re-execute
13831 ourselves with CONFIG_SHELL.
13833 2001-10-05 Paul Eggert <eggert@twinsun.com>
13835 * tests/Makefile.am (clean-local): Don't invoke $(TESTSUITE) if it
13836 doesn't exist. Remove *.tmp, as a .tmp file is created during the
13837 build of $(TESTSUITE).
13839 2001-10-05 Akim Demaille <akim@epita.fr>

13850 Fix the absolute path case/esac pattern.
13851 Provide $0 as fallback for as_myself.

13862 (AS_SHELL_SANITIZE): here. Use it.
13863 (_AS_LINENO_PREPARE): Preserve the exit status of $0.lineno.
13864 From Paul Eggert.
13866 2001-10-04 Akim Demaille <akim@epita.fr>
13868 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Use a portable
13869 combination of Awk and sed to replace $LINENO.
13871 2001-10-02 Paul Eggert <eggert@twinsun.com>
13873 * doc/autoconf.texi (Limitations of Builtins): You can't use
13874 "source"; it's not portable. Remove confusing and
13875 somewhat-incorrect example involving "." and "/".
13877 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): "source" -> ".", for
13878 compatibility with POSIX shells.
13880 2001-10-02 Akim Demaille <akim@epita.fr>
13882 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Just source 40.lineno
13883 instead of exec'ing to preserve $0 and $@.
13885 2001-10-01 Akim Demaille <akim@epita.fr>
13887 * tests/testsuite (AT_INIT) <at_pass_list>: New.
13888 Don't run twice the same test.

13906 * lib/autoconf/status.m4 (AC_OUTPUT_MAKE_DEFS):
13907 Don't use nested parenthesization. This patch was originally
13908 suggested to bug-autoconf by Philippe De Muyter on 2000-05-28,
13909 but somehow it didn't get incorporated then.
13910 * doc/autoconf.texi (Limitations of Usual Tools):
13911 Clarify remark about sed and nested parenthesization.
13913 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF):

13915 the type exists.
13916 * lib/autoconf/general.m4 (_AC_COMPUTE_INT_COMPILE):
13917 Check for `expr' arithmetic overflow, and for compilation failure,
13918 and invoke a new argument $4 if either is discovered.
13919 This makes _AC_COMPUTE_INT_COMPILE more like _AC_COMPUTE_INT_RUN.
13920 (_AC_COMPUTE_INT): Pass IF-FAILS arg to _AC_COMPUTE_INT_COMPILE.
13922 2001-09-28 Akim Demaille <akim@epita.fr>

13930 * lib/autotest/general.m4 (AT_VICTIMS): Rename as...
13931 (AT_TESTED): this.
13932 (AT_INIT): More the wrapped section to where it will be expanded.
13933 Output `AT_tested' only when existing.
13934 Catch unexpanded PACKAGE_STRING and PACKAGE_BUGREPORT.
13936 2001-09-27 Akim Demaille <akim@epita.fr>
13938 Fix the passing of $? to ACTION-IF-FAILED in AC_TRY_RUN, that
13939 generates too many bug reports.
13941 * lib/autoconf/general.m4 (_AC_RUN_IFELSE): Pass the right exit
13942 status when executing the ACTION-IF-FALSE.
13943 * tests/base.at (AC_TRY_*): Rename as...

13950 * tests/c.at (Extensions, C keywords)
13951 (Broken/missing compilers, AC_PROG_CPP with warnings)
13952 (AC_PROG_CPP without warnings, AC_PROG_CPP via CC)
13953 (AC_PROG_CPP requires AC_PROG_CC): here and...
13954 * tests/fortran.at (GNU Fortran 77): there.
13955 * doc/autoconf.texi (autoconf Invocation): Fix the example:
13956 AC_TRY_RUN is about compilation, not shell commands.
13957 (Test Programs): AC_TRY_RUN works as used to be advertised.
13959 2001-09-27 Akim Demaille <akim@epita.fr>
13961 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Fix bugs spotted by
13962 Raja R Harinath:
13963 Be sure to detect when $LINENO always returns the same value.
13964 Look for the original script, basename($0) is certainly not
13965 enough.
13966 Pass the CLI arguments to `$as_me.lineno'.
13968 2001-09-25 Akim Demaille <akim@epita.fr>
13970 * lib/autotest/general.m4 (AT_INIT): Dump the whole config.log.

13978 of --language now.
13980 2001-09-23 Akim Demaille <akim@epita.fr>
13982 * doc/autoconf.texi (Top): Wrap in @ifnottex.
13984 2001-09-23 Akim Demaille <akim@epita.fr>
13986 * lib/autoconf/status.m4 (_AC_SRCPATHS): Compute and provide
13987 ac_buildpath, ac_top_buildpath, ac_srcpath, and ac_top_srcpath.
13988 (_AC_OUTPUT_FILES): Also substitute srcpath, top_srcpath,
13989 builddir, buildpath, top_builddir, and top_buildpath.
13990 (_AC_OUTPUT_SUBDIRS): Compute the dir variables *before* changing
13991 the current directory.
13992 * lib/autoconf/general.m4 (_AC_INIT_HELP): Compute the dir
13993 variables *before* changing the current directory.

13996 variables.
13998 * lib/autotest/general.m4: Do not reset AT_victims.
13999 Don't compute at_srcdir nor at_top_srcdir.
14001 * tests/tools.at: Hence use top_srcdir.
14003 * tests/Makefile.am, tests/autoconf, tests/autoheader,
14004 * tests/autom4te, tests/autoreconf, tests/autoupdate, tests/ifnames:
14005 Remove.

14008 * tests/Makefile.am (DISTCLEANFILES, EXTRA_DIST): Adjust.
14009 * configure.ac: Build the position independent wrappers.
14011 * man/Makefile.am: Now that test wrappers are position
14012 independent, use them and drop dark envvar magic.
14014 2001-09-23 Akim Demaille <akim@epita.fr>
14016 * doc/autoconf.texi (Common Shell Constructs): Rename as...
14017 (Programming in M4sh): this.
14018 Promote to @section.

14047 2001-09-23 Tim Van Holder <tim.van.holder@pandora.be>
14049 * m4/auxdir.m4, m4/cond.m4, m4/depend.m4, m4/init.m4,

14061 * tests/Makefile.am (package.m4): Remove.
14063 2001-09-22 Akim Demaille <akim@epita.fr>
14065 Rely on `$LINENO' when possible instead of `__oline__'.
14067 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Provide some form of
14068 `$LINENO' support replacement when not supported.
14069 (_AS_CR_PREPARE, _AS_TR_CPP_PREPARE, _AS_TR_SH_PREPARE): Invoke
14070 them explicitly to be sure they are not output before this section
14071 (via m4_require). Cosmetic only.
14072 * lib/autoconf/c.m4, lib/autoconf/general.m4,
14073 * lib/autoconf/programs.m4: Replace all the occurrences of
14074 `__oline__' with `$LINENO'.

14077 2001-09-21 Tim Van Holder <tim.van.holder@pandora.be>
14079 * lib/autoconf/functions.m4 (_AC_FUNC_FORK): Replaceded an 8-bit
14080 character (u: -> ue) in a code comment.
14081 (AC_FUNC_LSTAT_FOLLOWS_SLASHED_SYMLINK): Only run 'ln -s' if we know
14082 it works.
14084 2001-09-21 Akim Demaille <akim@epita.fr>
14086 * Makefile.maint (AUTOM4TE): Neutralize autom4te.
14087 Suggested by Jim Meyering.
14089 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
14091 * lib/autoconf/programs.m4: Use extensions listed in
14092 $ac_executable_extensions when looking for programs.
14094 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
14096 * lib/autoconf/general.m4: Fix a small Englisho.
14097 * lib/autoconf/status.m4: Fix a small typo. Handle DOS paths when
14098 setting up ac_dir_suffix and ac_top_builddir.
14099 * lib/m4sugar/m4sh.m4: Default CDPATH to $PATH_SEPARATOR, not ':'.
14101 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
14103 * doc/autoconf.texi (File System Conventions): Clarify the use of
14104 PATH_SEPARATOR.
14105 (Special Shell Variables[PATH_SEPARATOR]): Ditto.
14106 (Special Shell Variables[CDPATH]): Mention that $PATH_SEPRATOR should
14107 be used instead of ':'.
14108 * lib/autotest/general.m4: Replace occurrences of ':' in
14109 AUTOTEST_PATH with $PATH_SEPARATOR at test suite startup.
14111 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
14113 * tests/atgeneral.m4: Add basic support for test ranges (e.g. 7-34) as
14114 arguments. Fixed a typo.
14116 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
14118 * man/Makefile.am (.x.1): Use @PATH_SEPARATOR@, not ':' to set up
14119 $PATH. Also set AUTOM4TE_CFG, so we can process autom4te properly.
14121 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
14123 * bin/autoscan.in: Add 'exec-perl-if-not-run-by-perl'.
14124 * bin/autoupdate.in: Ditto.
14125 * bin/autoheader.in: Reworded a few comments.
14126 * bin/autoconf.in: Reworded help text for a few options.
14127 * bin/autoheader.in, bin/autom4te.in, bin/autoreconf.in,
14128 * bin/autoscan.in, bin/autoupdate.in: Ditto.
14130 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
14132 * lib/Autom4te/XFile.pm (open): Simplified the error message (we
14133 already have $file). Set output files to binary mode (helps avoid
14134 CR issues on DOSish systems).
14136 2001-09-19 Akim Demaille <akim@epita.fr>
14138 * lib/autotest/general.m4: Englishoes.
14139 From Tim Van Holder and Alexey Mahotkin.
14141 2001-09-18 Paul Eggert <eggert@twinsun.com>
14143 * doc/autoconf.texi (Common Shell Constructs): New node,
14144 documenting AS_DIRNAME.
14145 (Limitations of Usual Tools): Refer to it when discussing dirname.
14146 Also, update discussion of POSIX standard to reflect latest draft.
14148 * lib/autoconf/c.m4:
14149 (AC_LANG_INT_SAVE(C)): Also support negative values, down to LONG_MIN.
14151 * lib/autoconf/general.m4 (_AC_COMPUTE_INT_COMPILE):
14152 Do not pass a first argument with leading '-'
14153 to expr, by parenthesizing initial integers that might be negative.
14155 * doc/autoconf.texi (Particular Functions): AC_FUNC_GETPGRP
14156 now merely checks whether it is an error to pass an argument
14157 to getpgrp.
14159 * lib/autoconf/functions.m4 (_AC_FUNC_GETPGRP_TEST): Remove.
14160 (AC_FUNC_GETPGRP): Don't bother with a runtime test. Just check
14161 whether it is a (compile-time) error to pass an argument to
14162 getpgrp. This simpler test supports the revised documentation,
14163 and is all that AC_FUNC_GETPGRP's users really need.
14165 2001-09-18 Akim Demaille <akim@epita.fr>
14167 * doc/autoconf.texi (Limitations of Make) <$<>: New.
14169 2001-09-18 Akim Demaille <akim@epita.fr>

14175 2001-09-18 Paul Wagland <paul@wagland.net>
14177 * tests/m4sh.at: Ensure that AS_DIRNAME handles '/', '//' and '///'
14178 correctly.
14179 Add test for AS_BASENAME.
14180 * lib/m4sugar/m4sh.m4: Fix AS_BASENAME so that it passes the previous
14181 added test. It now correctly handles /1/2/3/, returning '3' not ''.
14182 Added AS_BASENAME_SED to make the interface the same as AS_DIRNAME.
14183 * tests/base.at: Fixed the expected responses. The old ones were
14184 one line out...
14185 * lib/autoconf/general.m4: Fixed AC_PREFIX_PROGRAM, it now behaves as
14186 the documentation claims it should (and how it behaved in 2.13).
14188 2001-09-18 Akim Demaille <akim@epita.fr>
14190 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): No INIT-CMDS in
14191 the AC_CONFIG_COMMANDS invocation.
14192 This also solves the name clash problems.
14193 Don't set the package's ID.
14194 * lib/m4sugar/Makefile.am (version.m4): Revamp.
14195 No longer to be shipped.
14196 (version.in): Remove.
14197 * lib/m4sugar/m4sugar.m4, lib/autoconf/general.m4,
14198 * lib/autoconf/status.m4: Adjust.
14199 Use `m4_PACKAGE_STRING'.
14200 * lib/autotest/general.m4 (AT_INIT): N-th signature change: now
14201 the only optional argument is the name of the test suite.
14202 Expect `package.m4' to define the package signature.
14203 * lib/autom4te.in (Autotest): Add `package.m4?'.
14204 * tests/Makefile.am (package.m4): New.
14205 * tests/suite.at: ifnames is a victim.
14207 2001-09-18 Akim Demaille <akim@epita.fr>
14209 * lib/autom4te.in (Autoconf): Preselect AM_CONDITIONAL,
14210 AC_LIBSOURCE, AC_CONFIG_FILES.
14211 * lib/autotest/general.m4 (AT_INIT): Don't abort when a tested
14212 program version string doesn't match the package's.
14213 * lib/autoconf/general.m4 (AC_CACHE_VAL): Reestablish the space
14214 after `(cached)'.
14216 2001-09-17 Paul Eggert <eggert@twinsun.com>
14218 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):
14219 Allow expression to return any value that can fit into unsigned long
14220 (not int, as before). Check for output errors.
14222 2001-09-17 Bruno Haible <haible@ilog.fr>
14224 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):
14225 Always include <stdio.h> and <stdlib.h>. Evaluate
14226 the expression in an extra function before these includes. Call
14227 fprintf "%d" only after ensuring the argument is of type 'int'.
14228 Reported by Wayne Chapeskie <waynec@spinnaker.com>.
14230 2001-09-17 Paul Eggert <eggert@twinsun.com>
14232 Fix bug reported by Paul Townsend on AIX 4.3.3.0 with CFLAGS=-O4
14233 or CFLAGS=-O5. In that case, the linker has a relaxed view of
14234 fatal errors, and AC_CHECK_LIB causes it to include libraries even
14235 when they don't exist.
14237 * lib/autoconf/headers.m4 (AC_HEADER_DIRENT): Use AC_SEARCH_LIBS,
14238 not AC_CHECK_LIB, so that we don't use -ldir or -lx if we don't
14239 need it.
14241 * lib/autoconf/specific.m4 (AC_ISC_POSIX): Replace the old, crufty
14242 version with the version used by fileutils 4.1, except use
14243 AC_SEARCH_LIBS, not AC_CHECK_LIB, so that we don't use -lcposix if
14244 we don't need it.
14246 * doc/autoconf.texi (AC_ISC_POSIX): Describe new behavior.
14248 2001-09-13 Akim Demaille <akim@epita.fr>
14250 * tests/base.at, tests/m4sh.at: Be sure to issue the bangshe line
14251 _first_.
14252 Reported by Gerrit P. Haase.
14254 2001-09-13 Akim Demaille <akim@epita.fr>
14256 * lib/autotest/general.m4 (AT_INIT): Reset `AT_victims' so that
14257 m4_defn'ing is valid.
14259 2001-09-13 Akim Demaille <akim@epita.fr>
14261 * lib/m4sugar/m4sugar.m4 (m4_append_uniq): New.
14262 * lib/autotest/general.m4 (AT_VICTIMS, AT_KEYWORDS, _AT_CLEANUP_FILE):
14263 Use it.
14265 2001-09-13 Akim Demaille <akim@epita.fr>
14267 * lib/m4sugar/m4sugar.m4 (_AS_QUOTE_IFELSE, _AS_BOX_INDIR): Use
14268 m4_match.
14269 (m4_re_escape): New.
14270 * lib/autoconf/status.m4 (AC_CONFIG_IF_MEMBER): Use it.
14271 * lib/autoconf/general.m4 (AC_CACHE_SAVE): Use m4_match.
14272 * lib/autoconf/status.m4 (AC_CONFIG_IF_MEMBER, AC_CONFIG_LINKS):
14273 Likewise.
14274 * lib/autoconf/types.m4 (_AC_CHECK_TYPE_REPLACEMENT_TYPE_P)
14275 (_AC_CHECK_TYPE_MAYBE_TYPE_P, AC_CHECK_MEMBER): Likewise.
14276 * lib/autotest/general.m4 (AT_INIT): Rename AT_TESTS_ALL as
14277 AT_tests_all for consistency.
14278 Set at_victims.
14279 (AT_VICTIMS): Similar to AT_KEYWORDS.
14280 (_AT_CLEANUP_FILE_IF): Use m4_match and m4_re_escape.
14282 2001-09-13 Akim Demaille <akim@epita.fr>
14284 * lib/autotest/general.m4 (AT_INIT): Fix stupid bugs.
14286 2001-09-13 Akim Demaille <akim@epita.fr>
14288 * lib/autotest/general.m4 (AT_INIT): Create and remove
14289 `$as_me.[0-9]+' instead of `debug-[0-9]+.sh', so that multiple
14290 test suites can cohabit.

14400 2001-09-05 Akim Demaille <akim@epita.fr>
14402 Be ready to handle filenames as stupid as `dnl.at', for if even
14403 the maintainer is dumb enough to do that...
14405 * lib/autotest/general.m4 (AT_SETUP, AT_LINE): Demonstrates your
14406 excellence in M4 quotation: consider `__file__' is active.
14408 And BTW, when invoking m4, pass the --include in the right order:
14409 the wrong one.
14411 * bin/autom4te.in, bin/autoupdate.in: Use reverse when kingtal to
14412 4m.

14439 New, extracted from main.
14440 Use IO::File wherever possible.
14441 (input.m4): Be constant, use -I instead of hard coding $tmp.
14442 Therefore be a quoted heredoc.
14443 Don't invoke `_au_disable', since ac was not loaded, but just
14444 `unm4.m4'.
14446 2001-08-31 Akim Demaille <akim@epita.fr>
14448 Version 2.52d.

14471 2001-08-31 Akim Demaille <akim@epita.fr>
14473 * doc/autoconf.texi (Quadrigraphs): Document `@&t@'.
14474 (testsuite Scripts): There is no such thing as `atconfig.in'.
14475 And actually one diagram is missing: test suite runtime.
14477 2001-08-31 Akim Demaille <akim@epita.fr>
14479 * lib/Autom4te/General.pm (&find_file): Browse the includes in the
14480 inverse order.
14482 2001-08-31 Akim Demaille <akim@epita.fr>
14484 * bin/autoupdate.in (@include): `installcheck' revealed the path
14485 to m4sugar was lacking!
14487 2001-08-31 Akim Demaille <akim@epita.fr>
14489 * man/Makefile.am (.x.1): We really have to pass
14490 autom4te_perllibdir.
14492 2001-08-31 Akim Demaille <akim@epita.fr>
14494 * lib/autotest/general.m4 (AT_INIT): Don't pass all the args to
14495 debug scripts, in particular passing explicitly listed tests to
14496 run is stupid.
14498 2001-08-31 Akim Demaille <akim@epita.fr>
14500 * bin/autom4te.in (&parse_args): Strip `.' from `@include'.
14501 * bin/autoupdate.in: Use --include, -I, and --force, -f, too.
14502 Use directly autom4te, not autoconf.

14505 2001-08-31 Akim Demaille <akim@epita.fr>
14507 * tests/semantics.at (AC_C_BIGENDIAN): Missing eol.

14517 * bin/autoheader.in: Run directly autom4te --mode=autoconf, no
14518 need for autoconf.
14519 Promote --include over --macrodir and other obsolete options.
14521 2001-08-31 Akim Demaille <akim@epita.fr>
14523 * lib/Autom4te/General.pm ($version, $help, &getopt): New.

14525 * bin/autom4te.in ($autoconf): Pass --force.
14526 `print $out' doesn't print `$_' but `$out'.
14527 * tests/tools.at (Syntax of the Perl scripts): Pass the lib dir.
14528 (autoheader): Pass --force since the test suite goes too fast for
14529 the time stamps.
14530 Adjust to the new autoheader messages.
14532 2001-08-31 Akim Demaille <akim@epita.fr>
14534 * bin/autoheader.in: Handle the acconfig.h etc. junk files.
14535 Check the completeness of the #template.

14544 Drop AC_MACRODIR dead for real.
14545 * tests/atspecific.m4 (AT_CHECK_AUTOHEADER): Now autoheader says
14546 `autoheader: `config.hin' is created'.
14547 * tests/tools.at (Syntax of the Perl scripts): Check autoheader.
14549 2001-08-31 Akim Demaille <akim@epita.fr>
14551 * bin/autoheader.in: Rewrite in Perl.
14552 * tests/autoheader: Adjust.
14554 2001-08-31 Akim Demaille <akim@epita.fr>
14556 * bin/autoconf.in (--include, -I): New option.
14557 Map --localdir, --autoconf-dir onto it.
14558 Forward autom4te's options instead of interpreting them.
14559 * bin/autoconf.in, bin/autoheader.in (AC_MACRODIR, autoconf_dir):
14560 There is no such envvar since the inception of autom4te.cfg.
14561 * bin/autom4te.in (&parse_args): Uniquify `@include'.
14562 * bin/autoupdate.in: Adjust, and perform more control.

14566 2001-08-31 Akim Demaille <akim@epita.fr>
14568 * bin/autoconf.in: Don't bother with `acsite.m4' and `aclocal.m4'.
14569 * bin/autom4te.in (&find_file): Support `FILE?' standing for
14570 optionally `FILE'.
14571 Use -e, not -f, since /dev/null for instance is OK.
14572 (&parse_args): Adjust.
14573 * lib/autom4te.in (Autoconf): Add `acsite.m4?' and `aclocal.m4?'.
14575 2001-08-31 Akim Demaille <akim@epita.fr>
14577 * configure.ac: Also find tested executables in bin.
14578 * bin/autoconf.in, bin/autoheader.in, bin/autoreconf.in,
14579 * bin/autoscan.in, autoupdate.in: Use exclusively the name of the
14580 installed peer executables, only PATH is allowed to resolve it.
14581 Pass `autoconf_dir' via options, not via invisible envvars.
14582 * lib/Autom4te/General.pm (&find_peer): Remove.
14583 * lib/autotest/general.m4 (AT_INIT): `AUTOTEST_PATH=a:b' gives
14584 `abuild:asrc:bbuild:bsrc', not `abuild:bbuild:asrc:bsrc'.
14585 * man/Makefile.am: Let help2man rely on PATH instead of trying to
14586 find the executables for it.
14587 * tests/Makefile.am: Major cleanup. Too lazy to document...
14588 * tests/atlocal.in: Remove all the obscure envvar manipulations.
14589 We only need PERL.
14590 * tests/atspecific.m4, tests/tools.at: Passing --localdir is
14591 indeed related to running the test suite, while passing
14592 --autoconf-dir and others is related to running non installed
14593 Autoconf executables. So don't do that, leave it to...
14594 * tests/autoconf, tests/autoheader, tests/autom4te, tests/autoupdate,
14595 * tests/autoscan: New.
14596 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): Don't
14597 refer to library files: rely on --language.

14601 * bin/autom4te.in, lib/autom4te.in, bin/autoconf.in:

14610 2001-08-29 Akim Demaille <akim@epita.fr>
14612 * bin/autom4te.in (&handle_output): s/@__@/@&t@/.
14613 Suggested by Paul Eggert.
14615 2001-08-29 Akim Demaille <akim@epita.fr>
14617 * Makefile.maint (do-po-update): Wget refuses to overwrite files:
14618 download in a tmp dir.
14620 2001-08-29 Akim Demaille <akim@epita.fr>
14622 * lib/autotest/general.m4: s/AT-devnull/devnull/ since there are

14634 * bin/autoconf.in: Simplify and adjust.
14635 * tests/Makefile.am (AUTOMAKE): Use --set.
14636 * tests/atlocal.in: Adjust.
14637 * BUGS: distcheck and check are weak.
14639 2001-08-29 Akim Demaille <akim@epita.fr>
14641 * lib/autotest/general.m4: Use
14642 foo=`(command) 2>/dev/null`
14643 not
14644 foo=`command` 2>/dev/null
14645 (at-devnull): Rename as...
14646 (AT-devnull): this.
14647 (--clean): Remove AT-* files too.
14648 * doc/autoconf.texi (Limitations of Usual Tools): Document `date'.
14649 Reported by Nicolas Joly.

14683 * lib/autotest/general.m4 (AT_INIT): Log the command line.
14684 Support `VAR=VAL' as arguments.

14704 * lib/autoconf/status.m4 (_AC_SRCPATHS): Rename `ac_dots' as

14706 readable.

14708 * doc/autoconf.texi (Configuration Actions): Document the vars
14709 available in commands.
14710 Emphasize the risks of collisions in init-cmds.

15192 2001-08-07 Akim Demaille <akim@epita.fr>
15194 * lib/autotest/general.m4 (AT_INIT): All the `at-*' are to be
15195 removed.
15196 (at-setup-line): Huh? Be a variable `at_setup_line', not a file.
15197 No need to remove the files before and after the each test, before
15198 each test and at the end of the suite is enough.
15199 Display only the children `times', not the shell's.
15200 If the test failed or was skipped, at-times is not available.
15202 2001-08-07 Akim Demaille <akim@epita.fr>
15204 Always produce testsuite.log, including when there are no
15205 failures. This helps getting information on skipped tests, and
15206 duration of the tests. Err, implement the latter btw.
15208 * lib/autotest/general.m4 (AT_INIT): Set up fd 6 for the log.
15209 Dump information on the first run of each test.
15210 (AT_CLEANUP): Create `at-times' containing the duration of the
15211 test group.
15213 2001-08-07 Akim Demaille <akim@epita.fr>
15215 The use of `dumpstat' revealed that `len' was used although it
15216 should not. m4_text_wrap was using it, but in the Autoconf world
15217 where it is legal. Hence (i) test M4sh in its own world, not
15218 Autoconf's, and (ii), ahem, fix the bug :)
15220 * lib/autotest/general.m4: Be sure the set good quotes, as tracing
15221 does not like `' instead of [].
15222 (AT_INIT): Forbid `^_?AT_'.
15223 And don't output such tokens.
15224 * tests/Makefile.am (CLEANFILES): Add `script', `script.s4g',
15225 `script.as', and `autom4te.cache'.
15226 Remove `empty' and `macro' which are no longer used.
15227 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): New.
15228 * tests/m4sugar.at: Use it.
15229 * lib/m4sugar/m4sugar.m4: Use `m4_len' not `len'.
15231 2001-08-07 Akim Demaille <akim@epita.fr>
15233 * bin/autoconf.in, bin/autoheader.in: --force, -f is a new option.

15237 * bin/autom4te.in (handle_output): Typo in quadrigraph substitution.
15239 2001-08-04 Akim Demaille <akim@epita.fr>
15241 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA, AC_FUNC_ERROR_AT_LINE)
15242 (AC_FUNC_FSEEKO, AC_FUNC_OBSTACK): Use AC_LANG_IFELSE, not
15243 AC_TRY_LINK.
15244 * lib/autoconf/headers.m4 (AC_HEADER_MAJOR): Likewise.
15245 * lib/autoconf/fortran.m4 (_AC_LANG_PROGRAM_C_F77_HOOKS)
15246 (AC_F77_MAIN): Likewise.
15248 2001-08-04 Akim Demaille <akim@epita.fr>
15250 Don't rely on M4sugar outputting the patterns in files, since we
15251 might process the output _without_ running m4, hence without these
15252 files.
15254 * lib/m4sugar/m4sugar.m4 (m4_init): No need for `m4_tmpdir'.
15255 * bin/autom4te.in (@Request::includes): Remove, unused.
15256 (@Request::source): Rename as...
15257 (@Request::input): this.
15258 (@preselect): Add `m4_pattern_forbid' and `m4_pattern_allow'.
15259 (&handle_output): Fetch the patterns from the traces.
15260 `$forbidden' and `$allowed' are constant: use m//o.
15261 (&handle_m4): M4sugar no longer wants `m4_tmpdir'.
15262 (m4_pattern_forbid, m4_pattern_allow): Adjust for tracing only.
15264 2001-08-04 Akim Demaille <akim@epita.fr>
15266 `autoconf && autoheader' is sped up. Now, speed up `autoheader &&
15267 autoconf', i.e., in addition to caching traces, cache the output.
15269 * bin/autom4te.in (Request::cache): Rename as...
15270 (Request::id): this.
15271 ($cache, $icache, $tcache, $ocache): New.
15272 (&handle_m4): Save M4 output in the cache instead of $tmp.
15273 (&handle_output): Adjust.
15274 (&up_to_date_p): Check that the output cache is up to date too.
15275 (top level): Run `&handle_m4' iff force or the cache is invalid.
15276 Run `&handle_output' if the output cache is more recent.
15278 2001-08-04 Akim Demaille <akim@epita.fr>
15280 * bin/autom4te.in ($force): New.
15281 (&parse_args, &print_usage): -f, --force is a new option.
15282 (&handle_output): CPP directives might have spaces after `#'.
15283 (&parse_args): The first file only can be frozen.
15285 2001-08-04 Akim Demaille <akim@epita.fr>
15287 Don't let autom4te compute the `include' traces several times:
15288 first check that the trace cache file is up to date, and then
15289 compare its timestamp with that of the output.
15291 * bin/autom4te.in, bin/autoupdate.in, bin/autoscan.in: Normalize
15292 the preamble. Don't require 5.005 as Autom4te::General does it,
15293 and better yet (use `use', not `require'!).
15294 * lib/Autom4te/Struct.pm: Rename the last occurrences of
15295 Class::Struct as Autom4te::Struct.
15296 * lib/Autom4te/General.pm (File::stat): Use it.
15297 (&mtime): New, export it.
15298 * bin/autom4te.in: Use it.
15299 Declare `$req' is invalid if it is outdated.
15300 Don't declare it valid before saving it if something went wrong.
15302 2001-08-04 Akim Demaille <akim@epita.fr>
15304 Autom4te shall not encode Autoconf data, and preselecting traces
15305 must be proposed to the users.
15307 * bin/autom4te.in (@required_trace): Remove.
15308 (@preselect): New.
15309 (&parse_args, &print_usage): -p, --preselect is a new option.
15310 (&up_to_date_p): Adjust.
15311 * bin/autoconf.in: Preselect some Autoconf macros.
15313 2001-08-04 Akim Demaille <akim@epita.fr>
15315 * tests/tools.at (autoconf --trace: user macros): Check traces on
15316 macros invoked without arguments, and macros invoked with multiple
15317 lines arguments.
15319 2001-08-03 Alexandre Duret-Lutz <duret_g@epita.fr>
15321 * bin/autom4te.in (handle_traces): Fix rewriting of traces without
15322 arguments.
15324 2001-08-03 Akim Demaille <akim@epita.fr>
15326 * bin/autoconf.in ($@): Work around the usual sh bug.
15327 From Nicolas Joly.
15329 2001-08-03 Akim Demaille <akim@epita.fr>
15331 Clean up the handling of the M4 builtins tracing exception.
15333 * bin/autom4te.in (Request::request): Don't complete M4 builtins
15334 trace requests.

15336 (@m4_builtin): this.
15337 (%m4_builtin_alternate_name): New.

15344 * doc/autoconf.texi (Redefined M4 Macros): Document m4_exit,
15345 m4_if, and m4_wrap.

15349 * lib/m4sugar/m4sugar.m4 (m4_init): Also forbid `_m4_*' tokens.
15350 (m4_divert_pop): Dump the whole diversion stack when a diversion
15351 mismatch happens.
15352 * bin/autom4te.in (&handle_output): Remember of the first
15353 occurrence of a possibly undefined macro, not the last.
15354 Complain about the possibly undefined macros in the same order as
15355 the appear in the output.
15356 * lib/autoconf/Makefile.am (autoconf.m4f): List its dependencies.
15357 * tests/tools.at (autoconf: forbidden tokens, basic)

15359 autoconf's stderr, as it is now deterministic.
15360 Check that `dnl' is caught.
15362 2001-08-01 Akim Demaille <akim@epita.fr>
15364 * configure.ac: Bump to 2.52c.

15696 For some AWK, such as on HPUX 11, `xfoo' does not match `foo|^bar'.
15697 Reported by Michael Elizabeth Chastain.
15699 * autoconf.in: Refuse such AWK.
15700 * configure.in: Likewise.
15701 * Makefile.am (acversion.m4): Do not use move-if-change this file

15779 the right thing.
15780 * Makefile.am (.m4.m4f): Emphasize M4 error messages and fail
15781 earlier if there are.
15783 2001-07-03 Akim Demaille <akim@epita.fr>

15812 * aclang.m4 (AC_F77_DUMMY_MAIN): New macro to detect whether a
15813 dummy alternate main is required even if the user provides her own
15814 'main'.
15815 (AC_F77_MAIN): New macro to detect whether it is possible to
15816 provide an alternate 'main' function name, using the 'main' from
15817 the Fortran libraries.
15818 (AC_LANG_PROGRAM(C)): Use F77_DUMMY_MAIN, if it is defined, so that
15819 cross-language link tests can be performed successfully.
15820 (_AC_F77_NAME_MANGLING): Require AC_F77_DUMMY_MAIN. Also put $FLIBS
15821 after $LIBS, for consistency; this should be the general rule since
15822 the user may want to link to Fortran libraries that require $FLIBS.
15823 * doc/autoconf.texi: Document AC_F77_DUMMY_MAIN and AC_F77_MAIN.
15825 2001-06-29 Pavel Roskin <proski@gnu.org>
15827 * atgeneral.m4 (AT_CHECK): Add a newline to the end of
15828 at-stdout and at-stderr instead of removing the newline
15829 from the echo output, which is not guaranteed to work.

15861 2001-06-25 Akim Demaille <akim@epita.fr>
15863 * autoscan.in (%macro): Now maps from word to list of macros.
15864 (&init_tables): Die when a word which is already handled by
15865 explicit macros is mapped to the default macro.
15866 (&print_unique): Remove, inlined in...
15867 (&output_kind): here.
15868 (File::Basename): Use it.

15899 2001-06-23 Akim Demaille <akim@epita.fr>
15901 * acgeneral.m4 (_AC_INCLUDES_DEFAULT_REQUIREMENTS): Consider
