1123 (autotools and whitespace in file names): Use them.
1124 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
1125 Cover more potentially problemtic file names. Use the new
1128 Properly handle funny file names for headers in config.status.
1129 The test suite did not cover this bug because the code was not
1130 quoting properly the arguments of `rm -f' (which "fails" silently)
1131 as well as the arguments of `diff' (whose output was redirected to
1132 /dev/null so we couldn't see its error message).
1133 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Properly quote the
1134 file names passed to `rm' and `diff'.
1135 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):

1247 Add 'testsuite -C dir'.
1248 * lib/autotest/general.m4 (_AT_ARG_OPTION): Move missing argument
1250 (AT_INIT) <PARSE_ARGS_END>: ...here, since -k always takes
1252 <DEFAULTS>: Delay computation of variables based on $at_dir...
1253 <PREPARE_TESTS>: ...to here, since -C can change $at_dir.
1254 <TESTS>: Re-invoke via absolute name, since -C may be in effect.
1255 <PARSE_ARGS>: Parse new option.
1256 <HELP_TUNING>: Document it.
1257 * tests/autotest.at (Choosing where testsuite is run): New test
1259 (Keywords and ranges): Add test for missing -k argument.
1260 * NEWS: Document this.

1272 * doc/autoconf.texi (Particular Programs): Do not mention the
1273 Autoconf version in which the AC_PROG_INSTALL change was done.
1274 Suggested by Paul Eggert.
1276 2008-01-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1278 Fix --help=recursive with multiple AC_CONFIG_SUBDIRS.
1279 * lib/autoconf/general.m4 (_AC_INIT_HELP): If, for recursive help
1280 mode, we change to the source directory, also set $ac_pwd so we
1281 do not go back to the build tree for the next config subdir.
1282 * tests/torture.at (Deep Package): Extend test to contain two
1283 config subdirs on the top level.
1285 Fix parallel `maintainer-check'.
1286 * Makefile.am (maintainer-check-tests): Depend on `all'.
1287 Use `$(MAKE) $(AM_MAKEFLAGS)' instead of plain `make'.

1337 (m4_require): Use m4_do, not m4_join.
1339 Fix some whitespace tests on cygwin.
1340 * tests/tools.at (autom4te and whitespace in file names): Restore
1341 font-lock. Create $TMPDIR before it might be used.

1344 * tests/local.at (AT_CHECK_M4): Cater to new m4 error message.
1346 Optimize AC_REQUIRE.
1347 * lib/m4sugar/m4sugar.m4 (m4_expansion_stack_push, _m4_defun_pro)
1348 (_m4_defun_pro_outer, _m4_defun_epi, _m4_defun_epi_outer)
1349 (m4_require): Avoid extra macro calls.
1351 2007-12-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1353 * tests/torture.at (srcdir): Fix quoting.
1355 Do not pass top_srcdir to configure scripts in testsuite.
1356 * tests/autotest.at (srcdir propagation): Copy install-sh to
1358 (my only test): Drop setting of `top_srcdir'.
1359 * tests/base.at (Input/Output): Likewise.
1360 * tests/local.at (AT_CONFIGURE_AC): Copy install-sh,
1361 config.guess, and config.sub to test source tree.
1362 Drop AC_CONFIG_AUX_DIR setting.
1363 (AT_CHECK_CONFIGURE): Drop setting of `top_srcdir'.
1364 * tests/torture.at (Substitute a 2000-byte string): Drop
1365 AC_CONFIG_AUX_DIR setting, copy install-sh to test source tree.
1366 (Substitute a newline, datarootdir workaround): Likewise.
1367 (Define a newline): Adjust for linenumber changes in configure.ac.
1368 * tests/foreign.at (Libtool): Adjust comment to reflect changes.
1370 * tests/semantics.at (AC_PATH_PROGS_FEATURE_CHECK): Skip test
1371 if `pwd` contains whitespace.

1375 * tests/tools.at (Syntax of the shell scripts): Likewise.
1377 * tests/m4sh.at (LINENO): Quote $0.
1379 Fix testsuite program wrapper for whitespace in `pwd`.
1380 The problem here is that the usual mantra is that command
1381 variables can contain arguments, thus we cannot just escape
1382 $AUTOCONF, $AUTOM4TE etc. The compromise is to put the
1383 $top_builddir/tests directory early in $PATH, so that the
1384 wrappers are found by their plain name.
1385 * tests/wrapper.as: Put $testdir early in $PATH.
1386 (AUTOCONF, AUTOHEADER, AUTOM4TE): Set to plain command names.
1388 Proper config.status --file/--header and $srcdir escaping.

1398 <at_func_create_debugging_script, Driver Loop>:
1399 Quote $at_group_dir.
1400 * tests/autotest.at (whitespace in absolute testdir): New test.
1402 * lib/autom4te.in: Quote @datadir@.
1404 Proper file name escaping in Autoconf programs and Perl modules.
1405 This includes escaping of characters special to the shell
1406 as well as special to Perl, e.g., leading `<' or `>'.
1407 For example, when $file starts with `>', `open ">$file"'
1408 wrongly tries to append to a different file.
1409 * bin/autoconf.as: Fix quoting for autom4te options.
1410 * lib/Autom4te/General.pm (shell_quote): New function, taken
1411 from coreutils, written by Jim Meyering.
1413 * bin/autom4te.in (files_to_options, handle_m4): Use shell_quote
1415 * bin/autoreconf.in (parse_args): Likewise.
1416 * bin/autoscan.in (main): Likewise.

1418 * bin/autoheader.in: Likewise, fixing old insufficient escaping.
1419 * bin/ifnames.in: Likewise, XFile usage fixes.
1420 * tests/tools.at (autom4te and whitespace in file names): Extend
1421 test. Test twice, with special characters allowed on w32, and the
1422 rest. Test leading and trailing whitespace, for `open_quote'.
1423 (autotools and whitespace in file names): New, analogous test.
1424 Reported by Paul Eggert and Benoit Sigoure, additional suggestions
1425 by Russ Allbery and Eric Blake.

1429 lib/Autom4te/Struct.pm, lib/Autom4te/XFile.pm: Likewise.
1430 * lib/Autom4te/FileUtils.pm (open_quote): New function.
1431 (update_file, contents): Use it.
1433 * Makefile.am (autom4te-update): Rewrite for git.
1435 2007-12-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1437 * doc/autoconf.texi (autom4te Invocation, Autom4te Cache): Fix typos.
1439 Fix copyright years.
1440 * Makefile.am, doc/install.texi, lib/autoconf/fortran.m4,
1441 lib/autoconf/lang.m4, lib/freeze.mk: Likewise.
1443 2007-12-04 Eric Blake <ebb9@byu.net>
1445 Manually resync with gnulib, since 'make cvs-update' no longer works.

1449 When using older automake, don't downgrade build-aux/texinfo.tex.
1450 * configure.ac (AM_INIT_AUTOMAKE): Add no-texinfo.tex option.
1451 * doc/Makefile.am (TEXINFO_TEX): Add.
1453 2007-11-27 Paul Eggert <eggert@cs.ucla.edu>
1455 Fix AC_C_BIGENDIAN bug caused by new awk method of substitution.
1456 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Don't comment out the
1457 #undef as this runs afoul of our new way of creating config.h.
1458 Problem reported by Jim Meyering in
1459 <http://lists.gnu.org/archive/html/autoconf-patches/2007-11/msg00164.html>.
1461 2007-11-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1463 Fix autom4te for unusual characters in input file names.
1464 * bin/autom4te.in (files_to_options): Quote active characters
1466 * tests/tools.at (autom4te and white space in file names):
1469 * doc/autoconf.texi (Limitations of Usual Tools) <awk>:
1470 Document that Tru64 awk always splits $0.
1472 2007-11-24 Stepan Kasal <kasal@ucw.cz>
1474 * lib/autotest/general.m4 (AT_INIT): Do not extract the
1475 `#AT_STOP_...' line at the end of each test.
1477 2007-11-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1479 * lib/autotest/general.m4 (AT_INIT): For awk line number
1480 extraction script, ensure `$at_group' has a defined value
1481 even for the empty set, and properly quote its usage inside
1484 2007-11-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1486 * doc/autoconf.texi (Shell Functions): New chapter. Document
1487 IRIX sh $0 issue in functions, move content from ...
1488 (Portable Shell): ... here.
1489 (Shell Script Compiler): Note that shell functions are not
1490 totally unportable any more.
1492 2007-11-22 Stepan Kasal <kasal@ucw.cz>
1493 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1495 * lib/autotest/general.m4 (AT_INIT): Exit awk script after
1496 extracting the line numbers of the last needed test.
1498 2007-11-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1500 * lib/autotest/general.m4 (AT_INIT) <at_func_create_debugging_script>:
1503 2007-11-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1505 Fix IRIX testsuite debugging failures: $0 in functions.
1506 * lib/autotest/general.m4 (AT_INIT) <at_func_create_debugging_script>:
1507 Do not use $0 inside a function, as IRIX sh will set that to the
1508 function name rather than the script invocation name.
1510 2007-11-19 Paolo Bonzini <bonzini@gnu.org>
1511 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1513 * lib/autotest/general.m4 (at_func_test): Use cached line numbers
1514 to extract test scripts.
1515 (AT_INIT): Extract and cache test script line numbers.
1517 2007-11-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1519 * lib/autotest/general.m4: Revert 2007-11-15 patch and
1520 subsequent fixups; the awk -> here-document conversion trashes
1521 performance too much with AIX sh.
1523 2007-11-18 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1525 * tests/local.at: Do not test m4, perl with AT_TESTED.
1527 Diagnose and guard against write errors dealing with config.status.
1528 The general idea is this: all write failures from `configure'
1529 writing `config.status' are indicated by $ac_write_error, which
1530 is only checked at the end. This is safe because config.status
1531 code is not executed before the file is complete. Other write
1532 failures, be they inside config.status, or in sub shell/awk
1533 scripts spawned from configure or config.status, typically need
1534 earlier checking, as their results are used right afterwards.
1535 * lib/autoconf/status.m4 (AC_OUTPUT): Initialize `ac_write_fail'
1536 before writing config.status, check afterwards.
1537 (_AC_OUTPUT_FILES_PREPARE, _AC_OUTPUT_FILE)
1538 (_AC_OUTPUT_HEADERS_PREPARE,_AC_OUTPUT_CONFIG_STATUS):
1539 Set `ac_write_error' for write failures to config.status. Barf
1540 upon write failures to temporary files.
1541 Adjust note about closing and reopening the here-document.
1542 (_AC_OUTPUT_HEADER, _AC_OUTPUT_LINK, _AC_OUTPUT_COMMAND)
1543 (_AC_OUTPUT_MAIN_LOOP): Likewise, adjust note about closing and
1544 reopening the here-document.
1545 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
1546 Ensure `ac_write_error' does not escape into config.status.
1547 Also, add a couple of code paths not yet exercised in the test
1548 suite: a config file with input from stdin, and a config header

1552 2007-11-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1554 Avoid error with Tru64 awk and testsuite lines with many words.
1555 * lib/autotest/general.m4 (AT_INIT): In the awk script that
1556 reads the testsuite, set the field separator to an unusual value,
1557 in order to not run over the limit of 199 fields. Tru64 4.0D awk
1558 even splits the input if $i, i>0, was never accessed in the script.
1560 Revert 2007-10-17 change.
1561 * TODO: Multiline args in config files and headers mean something
1562 different and are not fixed, see

1570 AC_*_TOOL does not canonicalize the prefix
1571 * doc/autoconf.texi (Generic Programs): Do not say that
1572 the *_TOOL macros canonicalize, they simply use the `host_alias'.

1576 Diagnose write errors in config.status instantiations.
1577 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE)

1580 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):

1596 2007-11-15 Paolo Bonzini <bonzini@gnu.org>
1597 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1599 * lib/autotest/general.m4 (at_func_test): Remove.
1600 (AT_INIT): Pre-extract test groups into separate files.
1601 (AT_CLEANUP): Source pre-extracted file instead of calling at_func_test.

1618 * lib/autoconf/status.m4: Fix a couple of comment typos.
1620 * lib/m4sugar/m4sh.m4 (AS_TMPDIR): Use $as_me, not $me.
1622 2007-11-13 Jim Meyering <meyering@redhat.com>
1624 Clean up the rule to create "expr".
1625 * tests/Makefile.am (expr): Don't redirect directly to target.
1626 Redirect just once, not for each echo statement.
1627 Use $@, not literal "expr".
1629 2007-11-13 Paul Eggert <eggert@cs.ucla.edu>

1632 See: http://lists.gnu.org/archive/html/bug-gnulib/2007-11/msg00075.html
1633 * doc/autoconf.texi (Preprocessor Arithmetic): New section.
1634 (AC_TYPE_LONG_LONG_INT, AC_TYPE_UNSIGNED_LONG_LONG_INT):
1635 These no longer check for preprocessor flaws.
1636 * lib/autoconf/types.m4 (_AC_TYPE_LONG_LONG_SNIPPET):
1637 Do not check for preprocessor flaws.
1639 2007-11-13 Jim Meyering <meyering@redhat.com>
1641 Adapt dependencies, now that a version change doesn't modify configure.ac
1642 * GNUmakefile: Remove "make clean" kludge.
1643 * lib/m4sugar/Makefile.am (version.m4): Depend on Makefile, not
1645 Don't redirect directly to target.

1660 * tests/Makefile.am ($(srcdir)/package.m4): Likewise.
1662 2007-11-12 Jim Meyering <meyering@redhat.com>
1664 Add more non-srcdir build support.
1665 * GNUmakefile (dummy): Split a long line.
1666 Add -v option to autoreconf invocation.
1668 Remove the autoreconf-provided INSTALL, so that we regenerate it.
1669 * GNUmakefile (dummy): Remove INSTALL.
1671 Remove racy commands to build scripts in bin/ and tests/.
1672 * man/Makefile.am (.x.1): Now that scripts in bin/ and tests/
1673 are guaranteed to be built, remove the rules that tried to build
1674 them. Before, with a parallel build, these rules could lead to
1675 two processes writing tests/wrapper.in concurrently.
1677 Build in man/ only *after* building in bin/ and tests/.
1678 * Makefile.am (SUBDIRS): The man-page-creation process runs $(MAKE)
1679 in both bin/ and tests/.
1681 Accommodate non-srcdir build-from-checkout.
1682 * build-aux/git-version-gen: Require an additional parameter: $srcdir.
1683 Use git's --git-dir=$srcdir/.git option.
1684 Add quotes, in case tarball_version_file contains shell meta-characters.
1685 * GNUmakefile (_curr-ver): Pass $(srcdir) to git-version-gen.
1686 * configure.ac: Pass "." to git-version-gen.
1688 Avoid spurious test failures due to version skew.
1689 * GNUmakefile (dummy): Run $(MAKE) clean after autoreconf -i.

1711 2007-11-11 Benoit Sigoure <tsuna@lrde.epita.fr>
1713 Document that $((expression)) is not portable.
1714 * doc/autoconf.texi (Shell Substitutions): Here.
1716 2007-11-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1718 Ignore configure --help* errors due to LINENO-impaired shells.
1719 * tests/torture.at (Configuring subdirectories, Deep Package):
1720 In the --help* tests in read-only trees, make `.' temporarily
1721 writable again for the `stderr' file, and ignore errors due to
1722 the attempt to write configure.lineno.
1723 Report by Patrick Welche.
1725 2007-11-10 Jim Meyering <meyering@redhat.com>
1727 Generate package.m4 in build-dir, not srcdir.
1728 * tests/Makefile.am (package.m4): Adjust target.
1729 Don't redirect directly to $@.
1730 (CLEANFILES): Add package.m4.
1731 ($(TESTSUITE)): Depend on just-built package.m4, not the one
1733 When running $(AUTOTEST), search "." before searching $(srcdir).
1735 Avoid a race condition that would make parallel "distclean" fail.
1736 * tests/Makefile.am (distclean-generic): Replace the default,
1737 automake-provided rule with an identical one, but with an additional
1738 dependency on distclean-local. Simply adding the dependency would
1739 cause automake not to emit the rule at all.
1740 * BUGS: Building with -jN works, now.
1742 Distribute git-version-gen.
1743 * Makefile.am (EXTRA_DIST): Add build-aux/git-version-gen,
1744 since GNUmakefile is distributed, and requires it for dist* rules.
1746 Remove two more generated files from version control.
1747 * INSTALL: Remove generated file.
1748 * lib/autoscan/autoscan.list: Remove generated file.
1750 2007-11-09 Paul Eggert <eggert@cs.ucla.edu>
1752 * GNUmakefile (PATH): Remove stray apostrophes; they become
1753 part of PATH, which isn't wanted here.
1755 2007-11-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1757 New config files output variable `top_build_prefix'.
1758 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Substitute
1760 * doc/autoconf.texi (Preset Output Variables): Document it.
1762 Report by Bob Friesenhahn.
1764 Avoid expr for arithmetic evaluation if the shell accepts $((...)).
1765 * lib/autotest/general.m4 (AT_INIT) <at_func_arith>: New
1766 function, to parametrize arithmetic with expr vs. the shell.
1767 Use it where possible.
1768 Suggestion by Benoit Sigoure.
1770 2007-11-03 Benoit Sigoure <tsuna@lrde.epita.fr>
1772 Adjust the documentation of autotest WRT atlocal.
1773 * doc/autoconf.texi (Making testsuite Scripts): It is not necessary,
1774 when using Automake, to write a rule to produce atlocal, since it's
1775 an AC_CONFIG_FILES. Mention that atlocal.in needs to be
1776 distributed, not atconfig.in.
1778 2007-11-04 Eric Blake <ebb9@byu.net>
1780 Update list information.
1781 * README: Mention new autoconf-commit list.

1788 * lib/m4sugar/Makefile.am (version.m4): Another bash bug workaround.
1790 * build-aux/.gitignore: Ignore mkinstalldirs.
1792 * doc/autoconf.texi (autoreconf Invocation): Fix an underfull line.

1796 s/-/./ in snapshot version string: 2.61a-256-8b556 -> 2.61a.256-8b556
1797 * build-aux/git-version-gen: This syncs from coreutils.
1799 Adjust the build procedure so "make check" works reliably.
1800 * README-hacking: Include an extra step between "make" and
1801 "make check" to ensure that the latter passes.
1803 Use just-built tools, when possible.
1804 * GNUmakefile (PATH): Set and export here, ...
1805 (dummy): ... rather than here.

1854 2007-10-30 Bruno Haible <bruno@clisp.org>
1856 * lib/autoconf/types.m4 (_AC_TYPE_LONG_LONG_SNIPPET): New macro,
1857 extracted from AC_TYPE_LONG_LONG_INT and AC_TYPE_UNSIGNED_LONG_LONG_INT.
1858 (AC_TYPE_LONG_LONG_INT, AC_TYPE_UNSIGNED_LONG_LONG_INT): Use it.
1859 Fixes problem with Sun C 5.[0-8] in 32-bit mode, reported in
1860 <http://lists.gnu.org/archive/html/autoconf-patches/2007-10/msg00210.html>
1861 Suggested by Paul Eggert.
1863 2007-10-28 Jim Meyering <meyering@redhat.com>
1865 * README-hacking: Autoconf, Automake, and Perl are required to build.
1866 List Gzip and Tar separately. Suggested by Ralf Wildenhues.
1868 2007-10-28 Jim Meyering <meyering@redhat.com>
1870 README-hacking: Recommend running autoreconf -vi.
1871 * GNUmakefile (dummy): Use autoreconf -i, with appropriate PATH,
1872 so that we use just-built tools when they're available.
1873 Suggestions from Ralf Wildenhues.
1875 2007-10-28 Jim Meyering <meyering@redhat.com>
1877 Make inter-release --version output more useful.
1879 Now, each unofficial build has a version "number" like 2.61a-19-58dd,
1880 which indicates that it is built using the 19th change set
1881 (in _some_ repository) following the "v2.61a" tag, and that 58dd
1882 is a prefix of the commit SHA1.
1883 * build-aux/git-version-gen: New file.
1884 * configure.ac: Run it to set the version.
1885 (AM_INIT_AUTOMAKE): Don't check NEWS here.
1886 * Makefile.am (dist-hook): Arrange so that .version appears only
1887 in distribution tarballs, never in a checked-out repository.
1888 * .gitignore: Add .version here, too. Just in case.
1889 * tests/Makefile.am ($(srcdir)/package.m4): Depend on Makefile,
1890 not configure.ac, now that the version number changes automatically.
1892 Ensure that $(VERSION) is up to date for dist-related targets.
1893 * GNUmakefile: Arrange to rerun autoconf, if the version reported by
1894 git-version-gen doesn't match $(VERSION), but only for dist targets.

3165 AC_CHECK_TYPE, AC_CHECK_TYPES.
3166 * doc/autoconf.texi (Generic types): C types must be type-names
3167 (the C terminology), not type-ids (the C++ term). C++ types
3168 must not be anonymous.
3169 * lib/autoconf/types.m4 (_AC_CHECK_TYPE_NEW): Remove special case
3170 for C++; this drops support for anonymous struct and union types,
3171 which were problematic anyway.

3190 with objects too. Document the restrictions on its use.
3191 Document the restrictions on AC_CHECK_ALIGNOF's type argument.
3192 * lib/autoconf/types.m4 (_AC_CHECK_TYPE_NEW):
3193 For C, just try sizeof (TYPE) and sizeof ((TYPE)); if the former
3194 works but the latter doesn't, then it's a valid type.
3195 This lets people use function types and so forth.
3196 For C++ there doesn't seem to be a simple solution, so leave it alone.
3197 (AC_CHECK_SIZEOF): Allow argument to be a variable.
3198 (AC_CHECK_SIZEOF, AC_CHECK_ALIGNOF): Don't bother to invoke
3199 AC_CHECK_TYPE; that wasn't documented or necessary.
3201 2007-04-11 Stepan Kasal <kasal@ucw.cz>
3203 * lib/autoconf/general.m4 (_AC_LINK_IFELSE): Skip AS_TEST_X

3256 * doc/autoconf.texi: Adjust grammar around use of "heuristics".
3257 (Limitations of Usual Tools): Also list \< and \>, and mention that

3369 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Also
3370 AC_SUBST([MKDIR_P]), so that Automake < 1.10 will pick up its
3371 trace, if a package uses AC_PROG_MKDIR_P explicitly. The actual
3372 substitution will still be done by the special code.

3396 * lib/autoconf/programs.m4 (AC_PROG_SED): When closing a pipe
3397 early on the reader side, drop stderr of the input to avoid

3416 * doc/autoconf.texi (Signed Overflow Examples): Give more
3417 discussion about the allow_superuser_privileges example,
3418 and change it a bit to make things clearer.
3419 (Optimization and Wraparound): Clarify whether the compiler
3420 will generate an infinite loop for the example derived from
3421 Autoconf's mktime test.
3422 (Signed Overflow Advice): Say that -ftrapv is meant for debugging.
3423 Also, clarify unsigned multiplication overflow.
3425 2007-01-04 Eric Blake <ebb9@byu.net>
3427 * bin/Makefile.am (RELEASE_YEAR): New macro.

3437 2007-01-02 Paul Eggert <eggert@cs.ucla.edu>
3439 * doc/autoconf.texi (Integer Overflow): Revised based on today's
3440 feedback. The most important changes document what happens when
3441 you convert an out-of-range value to a signed integer type, and
3442 say that (sum < a) != (b < 0) reliably detects overflow when sum =
3445 * doc/autoconf.texi (Integer Overflow): Greatly expand and
3446 rewrite, taking notions from the recent discussion on the gcc and
3447 autoconf mailing lists; please see
3448 http://lists.gnu.org/archive/html/autoconf-patches/2006-12/msg00091.html
3449 and follow the many links.
3450 (Integer Overflow Basics, Signed Overflow Examples):

3452 (Signed Integer Division): New sections.
3454 2006-12-28 Steven G. Johnson <stevenj@alum.mit.edu>
3456 * lib/autoconf/general.m4 (AC_DEFINE_TRACE): Don't include
3457 preprocessor macro arguments in traced name.
3458 * doc/autoconf.texi (Defining symbols): Document longstanding
3459 support for AC_DEFINE-ing macros with arguments, and document
3460 behavior when the same variable has multiple AC_DEFINEs.
3461 * lib/autoconf/fortran.m4 (_AC_FC_WRAPPERS): Revert to the
3462 old implementation which AC_DEFINEs the FC_FUNC and FC_FUNC_
3463 macros directly, giving much shorter and simpler code.
3465 2006-12-28 Malcolm Purvis <malcolmp@xemacs.org> (trivial change)
3467 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Insert a
3468 space before "$ac_configure_args" to prevent a 'config.status
3469 --recheck' failure if ac_configure_args doesn't contain a leading
3470 space. This works around a problem with the XEmacs configure.ac,
3471 which uses the (undocumented) ac_configure_args variable
3472 inconsistently with Autoconf.
3474 2006-12-22 Paul Eggert <eggert@cs.ucla.edu>
3476 * lib/autoconf/functions.m4 (AC_FUNC_MKTIME):
3477 Include <limits.h>, and use its INT_MAX to rewrite the
3478 j loop so that it does not overflow 'int'. Problem reported by
3480 <http://lists.gnu.org/archive/html/bug-gnulib/2006-12/msg00084.html>.
3481 Play it safe by shifting left by 1 rather than multiplying by 2,
3482 as GCC is less likely to optimize this away when the value
3483 is signed (when it assumes overflow leads to undefined behavior).
3484 Also, don't assume time_t uses two's complement.
3486 2006-12-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3488 * tests/torture.at (Substitute a 2000-byte string): Avoid using
3489 a 10kB long (multi-line) string literal, OpenServer 5.0.7 ksh
3490 dumps core on it. Report by Tim Rice.

3494 * lib/autoconf/general.m4 (AC_ARG_ENABLE): Print help about
3495 --disable-option-checking to --help output even when
3496 AC_PRESERVE_HELP_ORDER is not used.
3497 (_AC_INIT_PARSE_ENABLE2): Print warnings using actual --enable or
3498 --with argument, rather than argument with [-.] replaced by
3500 * NEWS: Fix typo in previous change; the news was in the
3503 2006-12-18 Paul Eggert <eggert@cs.ucla.edu>
3505 * NEWS: Warnings are now generated by default for unknown
3506 --enable-* and --with-* options.
3507 * doc/autoconf.texi (Option Checking): Renamed from
3508 (Configure Option Checking). Tighten up the wording a bit.
3509 (External Software, Package Options): Cross-reference to Option
3510 Checking, and use this to shorten our section.
3511 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Prefer test -n
3512 "$x" to test "x$foo" != x.
3513 * lib/autoconf/status.m4 (AC_OUTPUT): Likewise.
3514 Don't warn if $enable_option_checking is "no".
3515 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Initialize
3516 ac_unrecognized_opts to the empty string.
3517 Don't echo the unrecognized opts, as this might mishandle
3518 backslashes or leading -.
3519 (AC_PRESERVE_HELP_ORDER): Put the --disable-option-checking
3520 usage next to the other --disable-FEATURE options in the
3523 2006-12-18 Steven G. Johnson <stevenj@alum.mit.edu>
3525 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS, _AC_INIT_PARSE_ARGS):
3526 (_AC_INIT_PARSE_ENABLE2, _AC_INIT_HELP, _AC_ENABLE_IF):
3527 Print warning for unrecognized --with and --enable options
3528 (AC_DISABLE_OPTION_CHECKING): New macro to disable warnings.
3529 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS, _AC_OUTPUT_SUBDIRS):
3530 Disable option checking when subdirs are configured.
3531 (AC_OUTPUT): If warnings are enabled, print warning about
3532 unrecognized --with and --enable options at the end of
3533 the configure output (as well as at the beginning).
3534 * doc/autoconf.texi (Option Checking): New node.
3535 Document new option warning functionality.
3537 2006-12-16 Eric Blake <ebb9@byu.net>
3539 * configure.ac (AC_INIT): Bump version, since 2.61a is released.
3540 * NEWS: Start news for current version.
3542 2006-12-15 Paul Eggert <eggert@cs.ucla.edu>
3544 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT):
3545 Define HAVE_GETMNTENT to 1, not to the empty string.
3546 Problem originally reported by Jochen Friedrich in
3547 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=403243>.
3549 This change prompted by a problem report by Andrey Simonenko in
3550 <http://lists.gnu.org/archive/html/bug-autoconf/2006-12/msg00026.html>.
3551 * doc/autoconf.texi (Defining Symbols): AC_DEFINE works for
3552 object-like macros only, in the traditional portable character
3554 * lib/autoconf/general.m4 (AC_DEFINE_TRACE_LITERAL):
3555 Warn about attempts to define things that are not identifiers.
3556 * lib/autoconf/fortran.m4 (_AC_FC_WRAPPERS): Rewrite to avoid
3557 awful hack that AC_DEFINEd macro names containing parentheses.
3559 2006-12-12 Paul Eggert <eggert@cs.ucla.edu>
3561 * doc/autoconf.texi: Undo some of the 2006-12-10 change. It was
3562 too drastic, even if Texinfo in theory requires it for info mode.
3564 (config.status Invocation): Renamed back from Recreating a
3566 (Obsolete config.status Use): Renamed back from Obsolete Recreation.
3567 (Autoconf 2.13): Renamed back from 20th-century Autoconf 2.
3569 2006-12-11 Paul Eggert <eggert@cs.ucla.edu>
3571 * NEWS: Version 2.61a.
3573 2006-12-11 Paul Eggert <eggert@cs.ucla.edu>
3574 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3576 * NEWS: Document changes with echo and printf, and the lack
3577 of limits on the total size of multi-line values of substituted
3578 variables, and the AC_FUNC_FSEEKO fix.
3580 2006-12-10 Paul Eggert <eggert@cs.ucla.edu>
3582 * doc/autoconf.texi (Writing Autoconf Input): Renamed from
3583 Writing configure.ac.
3584 (Autoconf Input Layout): Renamed from configure.ac Layout.
3585 (Recreating a Configuration): Renamed from config.status Invocation.
3586 (Obsolete Recreation): Renamed from Obsolete config.status Use.
3587 (acconfig Header): Renamed from acconfig.h.
3588 (20th-century Autoconf 2): Renamed from Autoconf 2.13.
3589 (Writing Testsuites): Renamed from Writing testsuite.at.
3590 (Autom4te Cache): Renamed from autom4te.cache.
3592 * BUGS: Remove mention of VPATH problem, since it's now documented
3593 not to be a bug in the Autoconf build procedure itself, but rather
3594 a problem with the proprietary `make' programs.
3596 * doc/autoconf.texi (Build Directories): Add a cross reference
3599 * build-aux/config.guess, build-aux/config.sub, build-aux/texinfo.tex:
3600 * doc/standards.texi: Sync from gnulib.
3602 * man/autoconf.1, man/autoheader.1, man/autom4te.1, man/autoreconf.1:
3603 * man/autoscan.1, man/autoupdate.1, man/config.guess.1:
3604 * man/config.sub.1, man/ifnames.1: Remove from CVS, since they're
3605 generated automatically.
3607 2006-12-06 Paul Eggert <eggert@cs.ucla.edu>
3609 * lib/autoconf/c.m4 (_AC_PROG_CC_C89): Also try -xc99=all, for Sun
3610 C 5.8 on Solaris 10. Using -xc99=all rather than -xc99 bypasses
3611 the buggy -xc99 option of Forte Developer 7 C on Solaris 9.
3613 2006-12-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3615 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Drop the
3616 `CEOF$ac_eof' special marker, the awk script cannot contain a
3617 line matching `^CEOF', so this is not needed any more.
3618 * tests/torture.at (Substitute a newline): Expose the `%!_!# '
3619 special marker in the test.
3621 2006-12-06 Stepan Kasal <kasal@ucw.cz>
3623 * tests/tools.at (autom4te preselections): Use `find -newer';
3624 remove one of the sleeps.
3626 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE): Make it
3627 more readable, using ...
3628 (_AC_INIT_PARSE_ENABLE2): ... this new helper macro.
3630 * doc/autoconf.texi (autoheader Invocation): Do not double-
3631 quote the parameter of `AH_BOTTOM' in the example.
3633 2006-12-05 Stepan Kasal <kasal@ucw.cz>
3635 * doc/autoconf.texi (Configuration Headers): Remove the
3636 example with multiple input files.
3637 (autoheader Invocation): Encourage `AH_BOTTOM', discouraging
3638 multiple input files.
3640 2006-12-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3642 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): When
3643 creating the awk substitution script, handle one input line at a
3644 time, so that the maximum length of a substituted (multi-line)
3645 value is not limited by the size of the sed pattern space.
3646 The trade-off is a slightly repetitive sed script.
3647 * doc/autoconf.texi (Limitations of Usual Tools): Branch labels
3648 can only have up to 7 characters, due to Solaris 10 /bin/sed.
3649 * tests/torture.at (Substitute a 2000-byte string): Increase the
3650 test with several long lines, they should not be caught by sed
3653 * tests/tools.at (autom4te preselections): New test, to flag
3654 entries missing from autom4te.cfg.
3655 Report by David Byron <dbyron@hheld.com>.
3657 * tests/torture.at (Substitute a 2000-byte string): Actually use
3658 AC_PROG_AWK, so the last change works as intended.
3659 (Substitute and define special characters): Likewise.
3660 (Substitute a newline): Likewise.
3662 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Use `$AWK'
3663 instead of `awk' consistently.
3664 (_AC_OUTPUT_CONFIG_STATUS): Initialize $AWK.
3665 * tests/torture.at (Torturing config.status): Test both the
3666 result of AC_PROG_AWK and plain awk.
3667 (Substitute a 2000-byte string): Likewise.
3668 (Substitute and define special characters): Likewise.
3669 (Substitute a newline): Likewise.
3671 2006-12-04 Paul Eggert <eggert@cs.ucla.edu>
3673 * lib/autoconf/functions.m4 (AC_FUNC_FSEEKO): Check that fseeko
3674 can be assigned to a function pointer. Problem reported by
3675 Peter Palfrader in <http://bugs.debian.org/401377>. Based on
3676 part of a patch by Ralf Wildenhues in that same bug report.
3678 2006-12-01 Paul Eggert <eggert@cs.ucla.edu>
3680 * tests/mktests.sh (ac_exclude_list): Exclude AC_FUNC_SETVBUF_REVERSED.
3681 * tests/semantics.at (AC_FUNC_SETVBUF_REVERSED): New test.
3683 2006-12-01 Eric Blake <ebb9@byu.net>
3685 * lib/autoconf/c.m4 (AC_LANG_INT_SAVE): Avoid newline, to aid in
3686 cross-compiling from cygwin to mingw.
3687 Reported by Bob Rossi. This resurrects the 2000-11-30 patch to
3688 aclang.m4, which was mistakenly removed in the 2001-09-17 patch
3689 to lib/autoconf/c.m4.
3691 2006-12-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3693 * lib/m4sugar/m4sh.m4 (_AS_ECHO_PREPARE): Use a longer test
3694 string for more reliable failure. Wrap the entire test that
3695 causes the broken Solaris printf to dump core, in a subshell,
3696 so the segmentation fault message is reliably suppressed.
3697 Fix shell expansion errors by using /usr/ucb/echo always;
3698 avoid an error on systems without it by another subshell.
3699 Avoid m4 expansion of `$1'. Set the zeroth argument of the
3700 subshell-$as_echo to `as_echo', for better error message.
3702 2006-11-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3704 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): If `BASH_ARGV' or
3705 `BASH_SOURCE' contain a newline, set them to empty, as they may
3708 2006-11-27 Paul Eggert <eggert@cs.ucla.edu>
3710 Turn AC_FUNC_SETVBUF_REVERSED into a noop. It's been obsolete for
3711 years and is too hard to maintain now. The last straw was
3712 reported by Jerker Baeck in
3713 <http://lists.gnu.org/archive/html/autoconf/2006-11/msg00102.html>.
3714 * NEWS: AC_FUNC_SETVBUF_REVERSED is now obsolete.
3715 * doc/autoconf.texi (Particular Functions): Move
3716 AC_FUNC_SETVBUF_REVERSED from here...
3717 (Obsolete Macros): ... to here. Say that it does nothing now.
3718 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
3719 Turn into (almost) a no-op.
3721 * lib/autoconf/c.m4 (AC_PROG_GCC_TRADITIONAL, AC_C_CONST):
3723 Do not recommend via AN_FUNCTION, AN_IDENTIFIER, or AN_HEADER.
3724 These macros are obsolescent and new applications shouldn't need them.
3725 * lib/autoconf/functions.m4 (AC_FUNC_CLOSEDIR_VOID, AC_REPLACE_FNMATCH):
3726 (AC_FUNC_GETLOADAVG, AC_FUNC_GETPGRP, AC_FUNC_MEMCMP):

3730 * lib/autoconf/headers.m4 (AC_HEADER_DIRENT, AC_HEADER_STAT):
3731 (AC_HEADER_STDC, AC_HEADER_SYS_WAIT, AC_HEADER_TIME): Likewise.
3732 * lib/autoconf/types.m4 (AC_STRUCT_TM): Likewise.
3734 * doc/autoconf.texi (Setting Output Variables): Mention that
3735 @VAR1@VAR2 has unspecified behavior. Problem reported by
3737 * NEWS: Mention this.
3739 * Makefile.am: Put only a single '#' into the copyright notice,
3740 so that it's also present in the output file. Standardize wording
3741 in makefile copyright notices to match GNU coding standards.
3742 * bin/Makefile.am: Likewise.

3755 2006-11-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3757 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Fix error
3758 in the sed script that mangles the awk script: delete up to the
3759 first exclamation mark only.
3760 * tests/torture.at (Substitute and define special characters):
3763 2006-11-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3765 Rewrite config files generation: avoid quadratic growth in
3766 the number of substituted variables by using awk instead of sed
3767 for the bulk of the substitutions.
3768 * NEWS: Mention this.
3769 * doc/autoconf.texi (Setting Output Variables): `|#_!!_#|' is also
3770 forbidden in the output (and thus input) file.
3771 * lib/autoconf/status.m4 (_AC_AWK_LITERAL_LIMIT): New macro.
3772 (_AC_OUTPUT_FILES_PREPARE): Instead of several sed scripts,
3773 generate just one large awk script for substitutions,
3774 eliminating much of the earlier complexity, while adding some
3775 new complexity. Only expand the substitution templates at
3776 configure time, for smaller configure script size. If
3777 _AC_SUBST_FILES are used, test 'awk' for working getline support
3778 at config.status time. If absent, interpolate through the
3779 shell. The awk script was written with much help
3780 from Paolo Bonzini and Paul Eggert.
3781 (_AC_SED_CMD_NUM, _AC_SED_DELIM_NUM, _AC_SED_FRAG): Removed.
3782 (_AC_SED_FRAG_NUM): Likewise.
3783 (_AC_SUBST_CMDS): Renamed from...
3784 (_AC_SED_CMDS): ...this.
3785 (_AC_OUTPUT_FILE): Use _AC_SUBST_CMDS.
3786 * tests/torture.at (Substitute a 2000-byte string): Also
3787 substitute a line with 1000 words, and a variable with several
3789 (Substitute and define special characters): Test awk special
3790 characters, and put substitution input strings `@foo@' in the
3791 output, to test that no recursion happens; test several other
3792 combinations from Paolo Bonzini.
3794 2006-11-25 Paul Eggert <eggert@cs.ucla.edu>
3796 * lib/autotest/general.m4 (AT_INIT): Undo recent changes
3797 that replaced echo with AS_ECHO where this wasn't necessary.
3798 Problem reportd by Ralf Wildenhues.
3799 * lib/m4sugar/m4sh.m4 (_AS_ECHO_PREPARE): Port to Solaris 7,
3800 where "/usr/bin/printf '%s\n' S" dumps core if S is long.
3801 This is Sun bug 4206210. Problem reportd by Ralf Wildenhues.
3803 2006-11-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3805 * lib/freeze.mk (GREP): Removed, no need to initialize this.
3807 2006-11-21 Paul Eggert <eggert@cs.ucla.edu>
3809 * doc/autoconf.texi (Limitations of Usual Tools): Don't claim
3810 that traditional Awk lacks 3-arg "split". It has it.
3811 Mention that FS must be a single character, and a few other
3812 99-byte limits of traditional Awk.
3813 Mention that if (i in a) doesn't work with traditional Awk.
3815 2006-11-18 Paul Eggert <eggert@cs.ucla.edu>
3817 * tests/autotest.at (BSx641-newline in command):
3818 (BS-BS-newline in command, BSx640-newline in command):
3819 (Newline-CODE-BS-newline in command):
3820 (Single-quote-BS-newline in command):
3821 (Single-quote-newline-BS-newline in command):
3822 Use printf '%s\n' instead of echo, for portability to hosts
3823 where echo interprets backslashes. This will break on hosts
3824 that lack printf, but for now let's assume all such hosts
3825 are dead (if not, we should get reports of test failures).
3827 2006-11-17 Paul Eggert <eggert@cs.ucla.edu>
3829 'echo' has some portability problems, when given a first argument
3830 with a leading '-', or when given any argument containing '\'.
3831 Avoid using 'echo' in these cases.
3832 * bin/Makefile.am $(bin_SCRIPTS): Rewrite to avoid 'echo' entirely.

3834 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
3835 * lib/autotest/general.m4 (AT_INIT): Likewise.
3836 * bin/autoconf.as: Use AS_ECHO rather than plain echo, when the
3837 argument might be unportable.

3856 (AS_TR_SH, AS_TR_CPP, AS_VAR_GET): Likewise.
3857 * bin/autoconf.as: Redo verbose flag implementation, as the old
3858 scheme wouldn't work with AS_ECHO.
3859 * lib/autotest/general.m4 (AT_INIT): Likewise.
3860 * lib/autoconf/general.m4 (AC_MSG_RESULT, AC_MSG_RESULT_UNQUOTED):
3861 Don't use ECHO_T, since ECHO_N is now reliable.
3862 * lib/autotest/general.m4 (AT_INIT): Likewise.
3863 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Use sed "$script"
3864 rather than using a here-document to put the script into a file.
3865 (_AC_DO_ECHO): Hoist the eval out of the echo, so that we can
3867 * lib/m4sugar/m4sh.m4 (AS_VAR_GET): Likewise.
3868 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Use
3869 AS_ECHO_N rather than ECHO_N and ECHO_C. This doesn't fix any
3870 bug, but we might as well stop using ECHO_N and ECHO_C internally.
3871 * lib/autotest/general.m4 (AT_SETUP): Likewise.

3873 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
3874 (_AC_OUTPUT_MAIN_LOOP): Rework echo so that it has just one
3875 operand, as AS_ECHO requires. Avoid double file name expansion.
3876 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Invoke _AS_ECHO_PREPARE.
3877 Don't set as_nl, since _AS_ECHO_PREPARE does that now.
3878 (_AS_PREPARE): Comment that _AS_ECHO_N_PREPARE is just for user code.
3879 (AS_ECHO, AS_ECHO_N, _AS_ECHO_PREPARE): New macros.
3880 * tests/c.at (AC_PROG_CPP without warnings, AC_PROG_CPP via CC):
3881 Double-quote strings that would otherwise contain M4 comments.
3882 * tests/m4sh.at (AS_ECHO and AS_ECHO_N): New test.
3884 * configure.ac (AC_INIT): Bump to 2.61a.
3887 2006-11-17 Paul Eggert <eggert@cs.ucla.edu>
3891 * configure.ac (AC_INIT): Bump to 2.61.
3894 * tests/autotest.at (Macro with backslash in a test title):
3895 Comment out for now, as this tests neither fails nor passes
3896 reliably. Problem reported by Ralf Wildenhues.
3898 2006-11-16 Paul Eggert <eggert@cs.ucla.edu>
3900 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE): Fix some typos
3901 in previous change, which caused test failures.
3903 2006-11-16 Stepan Kasal <kasal@ucw.cz>
3905 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Factor out
3906 code for --enable, --disable, --with, and --without to...
3907 (_AC_INIT_PARSE_ENABLE): ... a new macro.

3983 and non-portable sed scripts, and use $CONFIG_SHELL when invoking
3986 2006-11-08 Paul Eggert <eggert@cs.ucla.edu>
3988 * lib/autoconf/types.m4 (AC_TYPE_LONG_LONG_INT): Set
3989 ac_cv_type_long_long_int to 'yes' instead of 'cross-compiling'.
3990 Imported from a similar patch to gnulib by Bruno Haible.

4011 and Stepan Kasal <kasal@ucw.cz>
4013 Handle special characters in test case titles correctly.

4016 (AT_SETUP): M4-quote and AS_ESCAPE the title properly everywhere.
4017 * tests/autotest.at (AT_CHECK_AT_TITLE): Add EXPANDED-TITLE-TO-TEST
4018 argument. Extend to check titles printed by ./micro-suite and

4021 Single-quote in a test title,
4022 Double-quote in a test title): Don't expect failure anymore.
4023 (Backslash in a test title): Put a non-whitespace character after the
4024 backslash so that Bourne shells might actually see it as an escape
4026 (Brackets in a test title,
4027 Pound in a test title,
4028 Comma in a test title,
4029 Quoted Macro in a test title,

4033 Macro with double-quote in a test title,
4034 Macro with backslash in a test title): New tests expected to fail.
4035 * tests/torture.at (#define header templates): M4-quote this title in
4036 AT_SETUP call so that no M4 code is commented inadvertently somewhere.
4037 The visible effect was a stray [] in the testsuite output.
4039 2006-10-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4041 * doc/autoconf.texi (Limitations of Builtins): Do not invoke
4042 `trap ... 0' inside a function, for AIX sh.
4044 2006-10-26 Paul Eggert <eggert@cs.ucla.edu>
4046 * tests/base.at (AC_COMPUTE_INT): Test **0** rather than 1 / 0,
4047 since powerpc-apple-darwin8-gcc-4.0.1 (Apple Computer, Inc. build
4048 5363) simply issues a warning when dividing by zero at compile
4049 time. Problem reported by Elias Pipping.
4051 2006-10-26 Eric Blake <ebb9@byu.net>
4054 * doc/autoconf.texi (Evaluation Macros): Improve the example to
4055 show effect on macros that expand with commas.

4083 If FUNCTION-BODY is nonempty, use AC_LINK_IFELSE rather than
4084 AC_COMPILE_IFELSE, to work around problem with OSF/1 4.0F fseeko
4085 reported by Nelson H. F. Beebe for Coreutils 6.4.
4087 * tests/tools.at (autoconf --trace: user macros): Remove test
4088 for tracing multiline macros, since m4 1.4.7a uses a different
4089 way to number lines. Problem reported by Ralf Wildenhues.

4116 * doc/autoconf.texi (Caching Results): Likewise.
4117 * lib/autoconf/general.m4 (_AC_CACHE_CHECK_INT): Renamed from
4118 AC_CACHE_CHECK_INT, since it's no longer public.
4119 * lib/autoconf/types.m4: All uses of AC_CACHE_CHECK_INT changed.
4120 * tests/base.at (AC_COMPUTE_INT): Test this, not AC_CACHE_CHECK_INT.

4165 2006-10-14 Paul Eggert <eggert@cs.ucla.edu>
4167 (Imported from Automake.)
4168 * build-aux/install-sh (posix_mkdir): Reject FreeBSD 6.1 mkdir -p -m,
4169 which incorrectly sets the mode of an existing destination
4170 directory. In some cases the unpatched install-sh could do the
4171 equivalent of "chmod 777 /" or "chmod 0 /" on a buggy FreeBSD
4172 system. We hope this is rare in practice, but it's clearly worth
4173 fixing. Problem reported by Alex Unleashed in
4174 <http://lists.gnu.org/archive/html/bug-autoconf/2006-10/msg00012.html>.
4175 Also, don't bother to check for -m bugs unless we're using -m;
4176 suggested by Stepan Kasal.

4222 2006-10-13 Stepan Kasal <kasal@ucw.cz>
4224 * doc/autoconf.texi (Autoheader Macros): Warn that the text
4225 added to the template can get mangled.
4227 2006-10-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4229 * lib/autoconf/functions.m4 (AC_FUNC_OBSTACK): In the test,
4230 include the default headers, and redefine obstack_chunk_alloc
4231 and obstack_chunk_free. Fixes false failure with glibc.

4250 * lib/autoconf/specific.m4 (AC_USE_SYSTEM_EXTENSIONS): Likewise.
4252 * lib/m4sugar/m4sh.m4 (AS_TEST_X): New macro.
4253 (AS_EXECUTABLE_P): Use as_test_x rather than as_executable_p.
4254 (_AS_TEST_PREPARE): Set as_test_x rather than as_executable_p.
4255 Use a better substitute, by inspecting the output of "ls"
4256 rather than just using ":".
4257 * lib/autoconf/general.m4 (_AC_LINK_IFELSE): Use AS_TEST_X
4258 rather than AS_EXECUTABLE_P, since we needn't worry about
4259 non-regular files here.
4261 * NEWS: Autoconf-generated shell scripts no longer export BIN_SH,
4262 due to configuration hassles with this. See Tonya Underwood's report
4263 <http://lists.gnu.org/archive/html/bug-autoconf/2006-10/msg00003.html>.

4274 * lib/m4sugar/m4sh.m4 (AS_BOURNE_COMPATIBLE): Move the
4275 initialization which is not inherited through the environment
4276 (_AS_BOURNE_COMPATIBLE): ... to this new macro.
4277 (_AS_RUN): Call _AS_BOURNE_COMPATIBLE, not AS_BOURNE_COMPATIBLE.

4286 * lib/autoconf/c.m4 (_AC_PROG_PREPROC_WORKS_IFELSE): Remove
4287 comment about ac_cpp_err; it was incorrect, and anyway
4288 ac_cpp_err is being removed below.
4289 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE): Don't
4290 set ac_cpp_err to 'yesyes' if preproc_warn_flag and werror_flag
4291 are both 'yes'. In fact, don't bother setting ac_cpp_err at all;
4293 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't log our funky tests
4294 with werror_flag and conftest.err and so forth. This is more
4295 compatible with how _AC_PROG_PREPROC_WORKS_IFELSE behaves,
4296 and anyway the user shouldn't normally want to see this gorp logged.
4297 Problem reported by Ralf Wildenhues.
4298 * lib/autoconf/lang.m4 (AC_LANG_WERROR): werror_flag's default is
4299 empty, not 'no', since the rest of the code uses 'test -z'.

4303 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE):
4304 Use a single call to AC_DO_TOKENS rather than multiple, for
4306 (_AC_LINK_IFELSE): Test that resulting file is executable.
4307 Problem reported by mwoehlke in
4308 <http://lists.gnu.org/archive/html/bug-coreutils/2006-10/msg00048.html>.
4310 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Use "test -x /" rather
4311 than creating a file to use with test -x; this is much faster.
4313 2006-10-02 Bruno Haible <bruno@clisp.org>
4315 * lib/autom4te.in (Automake-preselections): Add
4316 AM_GNU_GETTEXT_INTL_SUBDIR, for automake 1.10.
4318 2006-09-27 Stepan Kasal <kasal@ucw.cz>
4320 * doc/autoconf.texi (Writing testsuite.at): Fix a typo: for
4321 standard error, `experr' should be used, not `expout'.

4325 * lib/autoconf/functions.m4 (AC_FUNC_FSEEKO): Don't compile the

4327 * lib/autoconf/specific.m4 (_AC_SYS_LARGEFILE_MACRO_VALUE):
4328 Set cache var to 'unknown' (not 'no') if leaving the macro unset
4329 still doesn't let the program compile.
4330 (AC_SYS_LARGEFILE): Test for _LARGE_FILES only if earlier tests
4333 * lib/autoconf/functions.m4: Fix problems reported by Ralf Wildenhues.
4334 (AC_FUNC_ERROR_AT_LINE): Don't bother to check for error.h. Just
4335 include it, without including anything else.
4336 (AC_FUNC_FSEEKO): Avoid gcc -Wall warnings about constant
4338 (AC_FUNC_STRNLEN): Require AC_USE_SYSTEM_EXTENSIONS.

4343 `error.h', and include it, for a `error_at_line' prototype.
4344 Use a nonempty format string in the link test.
4345 * lib/autoconf/functions.m4 (AC_FUNC_WAIT3): Include <sys/wait.h>,

4355 values. Problem reported by Ralf Wildenhues.

4517 except the first two arguments are reversed.
4518 * doc/autoconf.texi (Caching Results): New macro AC_CACHE_CHECK_INT.

4568 (_AC_PROG_LEX_YYTEXT_DECL): Handle caching correctly; the old code
4569 didn't work if some values were cached but not others. Test for
4570 broken lex libraries like native ia64-hp-hpux11.22; see
4571 <http://sources.redhat.com/ml/binutils/2003-12/msg00337.html>, and
4572 work around the problem by preferring an empty LEXLIB to -lfl or
4573 -ll. Let the user set LEXLIB='' to indicate no library needed.

4725 problems with arg script text that doesn't end in newline, and

4803 * tests/torture.at (Configuring subdirectories): Set CONFIG_SITE
4804 more globally, since the 2006-06-30 patch didn't suffice. Problem
4805 reported by Keith Marshall. Also, don't bother with builddir2,
4806 since it shouldn't be needed any more.
4808 2006-07-07 Paolo Bonzini <bonzini@gnu.org>

4827 2006-07-02 Paul Eggert <eggert@cs.ucla.edu>
4829 * lib/autoconf/types.m4 (AC_TYPE_LONG_LONG_INT):
4830 Require that long long int be at least 64 bits wide. C99 requires
4831 this and enough programs depend on it so we should check for it.
4832 Bruno Haible reports in
4833 <http://lists.gnu.org/archive/html/bug-gnulib/2006-06/msg00286.html>

4845 2006-06-28 Paul Eggert <eggert@cs.ucla.edu>
4847 * doc/autoconf.texi: Be more consistent about using @acronym with
4848 "HP" and "HP-UX". Remove mention of OSF; the old version wasn't
4849 quite right (it talked about "OSF/Tru64", even though the
4850 operating systems were called OSF/1, Digital UNIX, and Tru64 UNIX,
4851 and it even mentioned "OSF 4"!) and at this point there's little
4852 reason to talk about OSF any more, since it died in 1994.
4853 (Specific Compiler Characteristics): Simplify example of
4854 negative-size array.
4855 (File Descriptors): Reorder to make the text flow better.
4856 Remove joke about "appreciate the various levels"; I didn't get it.

4865 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Use -lX11, not
4866 -lXt in LIBS, idea from Karsten Hopp; this was due since
4869 2005-09-18 Paul Eggert <eggert@cs.ucla.edu>
4870 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Look for X11/Xlib.h
4871 and XrmInitialize rather than X11/Intrinsic.h and XtMalloc
4872 (which belong to Xt, not X itself). See Debian bug 327655.
4874 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4876 * configure.ac (AC_INIT): Bump to 2.60a.
4879 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4883 * configure.ac, NEWS: Update.
4885 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4887 * config/texinfo.tex: Sync from upstream.
4889 * bin/autom4te.in (handle_traces): Transform the `@S|@'
4890 quadrigraph correctly in traces.
4892 * NEWS, lib/Autom4te/C4che.pm, lib/autoconf/functions.m4:
4895 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Expand tests for
4896 datarootdir-related errors only if AC_DATAROOTDIR_CHECKED is
4898 * doc/autoconf.texi (Changed Directory Variables): New node,
4899 to document the whole `datarootdir' business a bit better.
4901 * tests/torture.at (datarootdir workaround): Extend test.
4902 Prompted by report by Alexandre Julliard.
4904 2006-06-22 Paul Eggert <eggert@cs.ucla.edu>
4906 * lib/autoconf/c.m4 (_AC_PROG_CC_C89): Check for C89 incompatibility
4907 when using default mode of IBM C 6 for AIX. Problem and two-line
4908 fix reported by Larry Jones.
4910 2006-06-22 Alexandre Julliard <julliard@winehq.org>
4912 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Avoid warning
4913 about literal '${datarootdir}' if a definition is found in the
4916 2006-06-20 Paul Eggert <eggert@cs.ucla.edu>
4918 * NEWS: Use "M4" rather than "m4" when appropriate.
4919 Problem reported by Eric Blake.
4920 * doc/autoconf.texi: Likewise.
4921 Use @acronym around BSD, GCC, and GNU when appropriate.
4922 (Why GNU M4): Renamed from "Why GNU m4".
4923 (Redefined M4 Macros): Mention that Posix
4924 m4wrap takes only 1 argument, but GNU M4 1.4.x takes more.
4925 (Buffer Overruns): Mention size_t and ptrdiff_t as alternatives
4928 2006-06-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4930 * bin/autom4te.in (handle_output): Do not forbid the empty
4932 * tests/tools.at (autoconf: the empty token): New test.
4934 2006-06-20 Stepan Kasal <kasal@ucw.cz>
4936 * lib/m4sugar/m4sugar.m4 (m4_init): Merge the two m4_wrap
4937 calls, so that we do not care whether they are LIFO or FIFO;
4938 in the m4_wrap, do not check which diversion is the topmost
4939 one, just check that the stack is balanced at the end.
4940 * lib/m4sugar/m4sh.m4 (AS_INIT): We are going to change the
4941 base diversion forever--pop the previous diversion before
4942 opening the new one; consequently, remove the m4_wrap call.
4943 * lib/autotest/general.m4 (AT_INIT): Likewise.
4944 * tests/m4sugar.at: Do not use
4945 m4_wrap([m4_diversion_pop([..])]), for educational purposes.
4947 2006-06-19 Paul Eggert <eggert@cs.ucla.edu>
4948 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4950 * NEWS: Document that m4wrap/m4_wrap might not be LIFO.
4951 * doc/autoconf.texi (Redefined M4 Macros): Likewise.
4952 Rework example of m4wrap token-pasting trouble so that it doesn't
4953 care whether it's LIFO or FIFO.
4954 Fix some "contrary to"s that are awkward in English.
4956 2006-06-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4958 * lib/autoconf/types.m4 (_AC_TYPE_INT): Set `$ac_cv_c_int$1_t'
4959 to `yes' instead of `int$1_t' if the type is found, for more
4960 consistent configure output (where $1 is the number of bits).
4961 (_AC_TYPE_UINT): Likewise for `uint$1_t'.
4962 Suggested by Bruno Haible.
4964 * lib/autoconf/types.m4 (_AC_TYPE_UNSIGNED_INT): Solaris 2.5.1
4965 needs _UINT8_T and _UINT64_T defines as well, to avoid clashes
4966 with system headers. Report by Bruno Haible.
4968 2006-06-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4970 * config/config.guess, config/config.sub: Sync from upstream.
4972 * bin/Makefile.am (autoconf.in): Use `--melt' for autom4te,
4973 in order to avoid picking up an older installed frozen m4sh.m4f.
4974 Besides an outdated shell startup, this could have been created
4975 by an earlier M4 version with incompatible frozen file format.
4977 2006-06-16 Paul Eggert <eggert@cs.ucla.edu>
4979 * README: Recommend m4 1.4.4 instead of 1.4.3..
4980 * doc/autoconf.texi: Likewise.
4981 (Special Chars in Names): Say that $(.FOO) is portable, as
4982 suggested by Stepan Kasal.
4983 (Installation Directory Variables, Build Directories):
4984 (Automatic Remaking, Subdirectories, Fortran Compiler):
4985 (Making testsuite Scripts, Defining Directories):
4986 Quote variable usages better.
4987 (Making testsuite Scripts): Add clean-local rule to makefile
4988 snippet, by Eric Blake.
4989 (Installation Directory Variables): Fix table item font.
4990 Reword slightly to clarify. Generalize advice about
4991 not using special characters to include all file-related
4992 vars, not just VPATH.
4993 (Special Chars in Variables): Warn about special characters in
4995 (Assignments): Clarify default-value example as suggested by
4997 <http://lists.gnu.org/archive/html/autoconf-patches/2006-06/msg00072.html>.
4998 (Special Shell Variables): Note leading ./ or ../, as suggested
5000 (Limitations of Builtins): Under cd, warn about CDPATH.
5001 (The Make Macro MAKEFLAGS): Untabify. Problem reported by
5004 2006-06-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5006 * doc/autoconf.texi (Configuration Actions): Remove duplicate
5007 `@var', for texi2html.
5008 (Systemology): Some more word wrapping, for DVI output.
5009 (autom4te Invocation): The short option for `--melt' is `-M',
5012 2006-06-15 Paul Eggert <eggert@cs.ucla.edu>
5014 * doc/autoconf.texi: More formatting and English tweaks,
5015 many suggested by Ralf Wildenhues.
5016 Reword to avoid "@code{...}'s" and the like, since it's ugly
5017 with Emacs info mode. discontents -> woes.
5018 Put a few "will"s back. time stamp -> timestamp.
5019 side-effect -> side effect.
5021 2006-06-14 Paul Eggert <eggert@cs.ucla.edu>
5023 * doc/autoconf.texi (Initializing configure, Shell Substitutions):
5024 Warn about $@ not persisting. Problem reported by Julien Danjou in
5025 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=372179>.
5026 (Special Chars in Names): Renamed from Leading _ in Macro Names.
5027 Mention other special chars, too.
5029 2006-06-14 Eric Blake <ebb9@byu.net>
5031 * doc/autoconf.texi (The Make Macro MAKEFLAGS): New node.
5033 2006-06-13 Paul Eggert <eggert@cs.ucla.edu>
5035 * doc/autoconf.texi: Some systematic minor improvements, as
5036 follows. Use "makefile" when talking about makefiles
5037 generally (which might be named "makefile" or "Makefile" or even
5038 "foo.mk"), "Makefile" when talking about a specific makefile
5039 called "Makefile". This unclutters the text from weird quotes
5040 (e.g., "`Makefile's" in info mode). Similarly, use "@var{foo}
5041 values" rather than "@var{foo}s" and similar constructs containing
5042 "}s". Use "Make rules" rather than "Makefile rules". Minor
5043 English-language improvements. Change the prefix "sub-" to "sub"
5045 Put blank lines around examples more consistently.
5046 Avoid "rather" and "very" as intensifiers.
5047 Avoid "will" as an auxiliary.
5048 (Limitations of Make): Split this node into....
5049 (Portable Make, $< in Ordinary Make Rules, Failure in Make Rules):
5050 (Leading _ in Macro Names, Backslash-Newline-Newline):
5051 (Backslash-Newline Comments, Long Lines in Makefiles):
5052 (Macros and Submakes, The Make Macro SHELL, Comments in Make Rules):
5053 (obj/ and Make, make -k Status, VPATH and Make):
5054 (VPATH and Double-colon, $< in Explicit Rules):
5055 (Automatic Rule Rewriting, OSF/Tru64 Directory Magic):
5056 (Make Target Lookup, Single Suffix Rules, Timestamps and Make):
5057 New nodes, resulting from splitup of Limitations of Make.
5058 All cross-references changed. Raise the top node from
5059 a section to a chapter, and all subnodes accordingly.
5060 Redo the introductory wording to match the new organization.
5061 (Installation Directory Variables): Use an example that is
5062 closer to what Autoconf actually does. Mention that VPATH's
5063 value should not contain metacharacters or white space.
5064 (Fortran Compiler): Fix a VPATH bug in an example.
5065 (Leading _ in Macro Names): Mention that this problem is no longer
5066 of practical concern.
5067 (VPATH and Make): Reword the advice to make it clearer
5068 that Autoconf and Automake support VPATH in non-GNU make, but
5069 many packages have bugs in this area.
5070 ($< in Explicit Rules): Refer to Build Directories rather
5071 than using a (non-VPATH-safe) example.
5072 (Automatic Rule Rewriting): Mention the sort of disaster that
5073 can ensue with Solaris-style rule rewriting with VPATH.
5075 2006-06-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5077 * doc/install.texi (Compilers and Options): Weaken the
5078 suggestion to use GNU make for VPATH builds.
5080 * lib/autom4te.in (Automake-preselections): Add AM_PROG_CXX_C_O,
5081 AM_PROG_F77_C_O, AM_PROG_FC_C_O, AC_FC_SRCEXT, AC_FC_FREEFORM.
5083 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Fix M4 quotation
5084 in regular expression.
5086 2006-06-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5088 * doc/autoconf.texi (Installation Directory Variables):
5089 Drop extra @samp from `@table @samp' item.
5090 (Limitations of Usual Tools): Comment fix.
5091 Do not nest @samp just to point to other table items.
5092 (Writing testsuite.at) <AT_CHECK>: The second argument to
5093 `@dvar' is already @samp'ed.
5094 (Making testsuite Scripts) <AC_CONFIG_TESTDIR>: Likewise,
5095 do not use @var in the second argument.
5097 2006-06-07 Paul Eggert <eggert@cs.ucla.edu>
5099 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Look for
5100 $as_shell.exe too. Problem reported by Andreas Buening in
5101 <http://lists.gnu.org/archive/html/autoconf/2006-06/msg00038.html>.
5103 2006-06-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5105 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA): Work around
5106 `unused variable' compiler warning, for `-Wall -Werror'.
5107 Reported by Jaap Haitsma in
5108 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00012.html>.
5110 2006-06-06 Paul Eggert <eggert@cs.ucla.edu>
5112 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Remove core file, in
5113 case the compiler dumps core. Problem reported for
5114 OpenServer 5.0.7 by Tim Rice in
5115 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00019.html>.
5116 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE):
5119 2006-06-06 Tim Rice <tim@multitalents.net>.
5121 * lib/freeze.mk: Quiet check-forbidden-patterns so the string
5122 "ERROR" only shows up in "make check" output if there is an
5125 2006-06-06 Eric Blake <ebb9@byu.net>
5127 * tests/tools.at (automatically allowed tokens): Fix typo.
5129 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
5131 * NEWS: Don't blame non-GNU VPATH compatibility issues on Automake.
5133 * doc/autoconf.texi (Integer Overflow): Mention that INT_MIN % -1
5134 typically overflows on x86 CPUs, even though the C standard
5137 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5139 * configure.ac (AC_INIT): Bump to 2.59e.
5142 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5146 * config/texinfo.tex: Sync from upstream.
5148 * bin/autoreconf.in: Trace `LT_CONFIG_LTDL_DIR'; if it has been
5149 seen, invoke libtoolize with `--ltdl' argument.
5150 * lib/autom4te.in (Autoreconf-preselections): Adjust.
5152 Suggested by Eric Blake.
5154 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
5156 * NEWS: Whoops! AC_FUNC_STRNLEN isn't obsolescent. Problem
5157 reported by Ralf Wildenhues.

5160 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5164 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
5166 * doc/autoconf.texi: Modernize some of the references to Solaris.
5168 2006-06-05 Stepan Kasal <kasal@ucw.cz>
5170 * lib/m4sugar/m4sugar.m4 (m4_require): Modify the error
5171 message issued by AC_REQUIRE.
5172 * tests/m4sugar.at: Check m4_require's error message.
5173 * tests/base.at: Check AC_REQUIRE's error message.
5174 * tests/local.at (AT_CHECK_M4): New macro, almost identical
5176 (AT_CHECK_AUTOM4TE): ... which is now a thin wrapper around
5178 (AT_CHECK_AUTOCONF): Use AT_CHECK_M4; no longer support
5179 `expout' as the last parameter.
5180 * tests/tools.at: Adapt to the above change.
5182 2006-06-04 Stepan Kasal <kasal@ucw.cz>
5184 * doc/autoconf.texi (Limitations of Usual Tools): Correct
5185 information about race-free implementations of mkdir.
5187 2006-06-04 Eric Blake <ebb9@byu.net>
5189 * bin/autoreconf.in (help): Document M4 environment variable.

5192 * doc/autoconf.texi (autom4te Invocation): Likewise.
5194 2006-06-04 Paul Eggert <eggert@cs.ucla.edu>
5196 * NEWS: GNU make now recommended for VPATH builds.
5197 Mention that some macros are now documented to be obsolescent.
5198 * doc/autoconf.texi:
5199 Prefer "current" to "modern" to describe
5200 currently-used (albeit perhaps old-fashioned) hosts.
5201 Mention which ancient features no longer need to be worried about.
5202 setgid -> set-group-ID
5203 setuid -> set-user-ID (these are the Posix terms)
5204 Fix some misuses of "only".
5205 (AC_C_BACKSLASH_A, AC_C_CONST, AC_C_PROTOTYPES):
5206 (AC_C_STRINGIZE, AC_C_VOLATILE, AC_FUNC_CLOSEDIR_VOID):
5207 (AC_FUNC_GETPGRP, AC_FUNC_LSTAT, AC_FUNC_MEMCMP):
5208 (AC_FUNC_SELECT_ARGTYPES, AC_FUNC_SETPGRP):

5215 (Installation Directory Variables): shall -> should
5216 (File Descriptors): Mention that 0, 1, 2 might get reopened.
5217 Mention that it's now safe to use 3 and 4.
5218 (Limitations of Usual Tools): cp -r is now specified by Posix.
5219 Omit longwinded and obsolescent discussion of cp -f.
5220 Modernize discussion of expr, ls.
5221 (Limitations of Make): Modernize discussion of VPATH builds.
5222 Mention $? as a workaround in some cases.
5223 * doc/install.texi (Basic Installation):
5224 Mention "./configure; make; make install" first. Be more
5225 specific about why this file is generic. Remove unnecessary
5226 parens. Remove misleading "only". Remove obsolete advice
5227 about csh. Don't say "configure" takes awhile; say it
5228 might take a while. Suggest CFLAGS=-g rather than CFLAGS=-O2,
5229 and CC=c99 rather than CC=c89, as these are blessed by current
5230 Posix. Recommend GNU make if doing a VPATH build.
5232 2006-06-03 Paul Eggert <eggert@cs.ucla.edu>
5234 * doc/autoconf.texi: Use a consistent style "$ @kbd{...}" for
5235 examples involving shell prompts.

5238 and Paul Eggert <eggert@cs.ucla.edu>
5240 * doc/autoconf.texi (Here-Documents): Add details about the
5241 pre-ksh93g bug. Reword slightly to make it clearer. Consistently
5242 use "here-documents" instead of "here documents".
5244 2006-06-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

5250 * doc/autoconf.texi (File System Conventions): Warn about ":"
5251 anywhere in directory names.
5253 2006-05-31 Paul Eggert <eggert@cs.ucla.edu>
5255 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be even more conservative
5256 about quoting the case statement, just in case.

5272 argument with leading hyphen. Problem reported by Paul Eggert.
5274 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
5276 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be more conservative
5277 about quoting ac_try: quote all of it, if any of it seems suspicious.
5278 This means we don't have to worry about ${ or sed any more.
5279 Also, double-quote the case statement, to work around misuses via
5280 underquoting as reported by Ralf Wildenhues in
5281 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00169.html>.
5282 (_AC_EVAL_STDERR): Revert, since evidently some packages rely on this
5283 undocumented and dangerous macro.
5284 Problem reported by Ralf Wildenhues in
5285 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00168.html>.
5287 2006-05-31 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5289 * lib/m4sugar/m4sh.m4 (_AS_DIRNAME_PREPARE): Check whether
5290 `dirname -- /' returns `/', for SunOS dirname scripts that escaped.

5293 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
5295 * lib/autoconf/general.m4: Revert AC_TRY_EVAL and AC_TRY_COMMAND,
5296 since evidently some packages rely on the old, broken behavior.
5297 Problem reported by Ralf Wildenhues in
5298 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00160.html>.
5299 (AC_TRY_EVAL, AC_TRY_COMMAND, _AC_EVAL): Go back to the
5300 pre-2006-05-26 definitions, but leave in the comments that
5301 these macros are dangerous and should not be used.
5302 (_AC_DO_ECHO): Renamed from _AC_EVAL_ECHO. All callers changed.
5303 (_AC_DO): Renamed from _AC_EVAL. All callers changed.
5304 (_AC_DO_STDERR): Renamed from _AC_EVAL_STDERR. All callers changed.
5305 (_AC_DO_VAR): Renamed from AC_TRY_EVAL.
5306 (_AC_DO_TOKENS): Renamed from AC_TRY_COMMAND.
5308 2006-05-29 Paul Eggert <eggert@cs.ucla.edu>
5310 * lib/autoconf/status.m4 (AC_OUTPUT_MAKE_DEFS): Rewrite to avoid
5311 the use of 'tr', since this is our only use of 'tr'.
5313 2006-05-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5314 and Paul Eggert <eggert@cs.ucla.edu>
5316 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE):
5317 Don't assume 'grep' works on long lines, since AIX grep doesn't.
5319 2005-05-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5321 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Do not use `grep' on
5322 the output file in the `${datarootdir}' test.
5324 2005-05-28 Stepan Kasal <kasal@ucw.cz>
5325 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5327 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If we have not seen
5328 mention of `datarootdir' in the input file(s), but literal
5329 `${datarootdir}' in the output file, and we haven't warned yet,
5330 then warn as well: the user may have (erroneously) used
5331 `AC_SUBST([mydatadir], [$datadir/my])' instead of the correct
5332 `AC_SUBST([mydatadir], ['${datadir}/my'])'.
5333 * tests/torture.at (datarootdir workaround): Extend this test.
5336 2006-05-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5337 and Paul Eggert <eggert@cs.ucla.edu>
5339 * doc/autoconf.texi (autoheader Invocation): The first argument to
5340 `AC_DEFINE_UNQUOTED' need not be a literal. Mention the
5341 alternatives and clear up the language a bit.
5343 2006-05-27 Paul Eggert <eggert@cs.ucla.edu>
5345 * NEWS: Reword notice for AC_TRY_COMMAND, AC_TRY_EVAL,
5346 ac_config_guess, ac_config_sub, ac_configure.
5347 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
5348 Fix typo that prevented an unnecessary space from being removed.
5349 Problems reported by Ralf Wildenhues in:
5350 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00143.html
5352 2006-05-26 Paul Eggert <eggert@cs.ucla.edu>
5354 * doc/autoconf.texi (Particular Programs, Limitations of Usual Tools):
5355 Use better wording to talk about AC_PROG_MKDIR_P's thread-safety.
5356 Don't use the term "thread-safe" to talk about mkdir race
5357 conditions, since the problem is more a process than a thread
5358 issue. Problem reported by Stepan Kasal in:
5359 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00088.html
5360 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Use code that mimics
5361 the test for 'install' more closely. Look at MKDIR_P first.
5362 Look in the PATH, and at /opt/sfw/bin.
5363 Look for a 'gmkdir' program as well (Solaris 10 /opt/sfw/bin/gmkdir).
5364 Don't bother to try mkdir -p, since we already check mkdir --version;
5365 just look at the version number. (There's no easy way to check
5366 for race-free implementations.)
5367 * tests/tools.at (autoconf: subdirectories): Adjust to above
5368 changes, since MKDIR_P now might end in "/mkdir -p".
5370 * doc/autoconf.texi (autoheader Invocation): Mention that the
5371 first arg of AC_DEFINE_UNQUOTED must be a literal.
5372 Problem reported by Ben Pfaff in
5373 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00090.html>.
5375 * NEWS: Mention that AC_TRY_COMMAND and AC_TRY_EVAL may be removed.
5376 * doc/autoconf.texi (Special Chars in Variables): New section.
5377 (Preset Output Variables): Warn about special chars in CPPFLAGS.
5378 (Installation Directory Variables): Quote $(datadir) better.
5379 (Limitations of Builtins): Describe some of eval's trickiness.
5381 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Simplify quoting.
5382 * lib/autoconf/fortram.m4 (_AC_PROG_FC_V_OUTPUT): Likewise.
5383 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Put leading space
5384 in front of every arg, not just trailing args. Quote apostrophes.
5385 (_AC_EVAL_ECHO): New macro.
5386 (_AC_EVAL, AC_EVAL_STDERR): Use it. Quote arg of eval.
5387 (AC_TRY_EVAL, AC_TRY_COMMAND): Mention that these macros might get
5389 (_AC_LINK_IFELSE): Use proper rule for shell continuation lines,
5390 exposed by quoting of eval argument. Put the command on line line
5392 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): Use eval more safely.
5393 (_AC_PATH_X, AC_PATH_X): Quote more safely.
5394 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Use eval more safely.
5395 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Don't use eval.
5396 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Minor style change.
5397 Handle special chars in prefix, ac_srcdir, ac_aux_dir.
5398 Use eval more safely.
5399 (_AC_OUTPUT_CONFIG_STATUS): Adjust to above changes.
5400 * lib/m4sugar/m4sh.m4 (AS_VAR_GET): Note that this API needs
5402 * tests/base.at (AC_TRY_COMMAND): Use proper rule for shell continuation
5403 lines, exposed by quoting of eval argument.
5405 2006-05-26 Stepan Kasal <kasal@ucw.cz>
5406 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5408 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Drop the
5409 initialization of `ac_cv_exeext', do not override it if it was
5410 already set, unless it was set to `no', for compatibility with
5411 Autoconf-2.13, and comment this.
5412 Do not export `ac_cv_exeext', Libtool hasn't needed this for years.
5413 (_AC_COMPILER_EXEEXT_DEFAULT): Likewise, do not export it.
5414 (_AC_COMPILER_EXEEXT_WORKS, _AC_COMPILER_EXEEXT_CROSS): Typos.
5415 * doc/autoconf.texi (Compilers and Preprocessors) <EXEEXT>:
5416 Document that this test may be overridden by setting
5419 2006-05-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5421 Revert these two patches:
5423 2006-04-06 Eric Blake <ebb9@byu.net>
5424 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_O): Inside cache
5425 check, s/ac_exeext/ac_cv_exeext/. Fixes regression introduced
5428 2006-04-01 Stepan Kasal <kasal@ucw.cz>
5429 Clean up _AC_COMPILER_EXEEXT* macros.
5430 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't try to
5431 detect exeext, it will be done by _AC_COMPILER_EXEEXT_O; just set
5432 ac_file to the name of the default output file and call
5433 _AC_COMPILER_EXEEXT_WORKS. Move the definition of ac_files and the
5434 initial `rm' of the candidate files...
5435 (_AC_COMPILER_EXEEXT): ... here and simplify them. Moreover, use
5436 the same list in subsequent `rm' calls, and for the temporary
5437 redefinition of ac_clean_files; call _AC_COMPILER_OBJEXT at the end,
5438 and don't call the other _AC_COMPILER_EXEEXT_* macros directly, use...
5439 (_AC_COMPILER_EXEEXT_TESTS): ... this new macro.
5440 (_AC_COMPILER_EXEEXT_O): Don't export ac_cv_exeext, it's not needed (or
5441 no longer needed) by libtool. Make it a cache check.
5442 (_AC_COMPILER_EXEEXT_CROSS): Remove the comment, it was obviously
5443 copied here by mistake.
5444 (AC_NO_EXECUTABLES): Redefine _AC_COMPILER_EXEEXT_TESTS, not
5445 _AC_COMPILER_EXEEXT.
5446 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX, AC_PROG_OBJC): Do not call
5447 _AC_COMPILER_OBJEXT directly.
5448 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
5450 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5452 * doc/autoconf.texi (Limitations of Usual Tools) < sed (`t')>:
5453 Fix description of how the buggy `sed' works.
5455 2006-05-25 Noah Misch <noah@cs.caltech.edu>
5459 * lib/Autom4te/XFile.pm (lock): Allow EOPNOTSUPP, besides
5460 ENOLCK. Only mention `make -j' when applicable. Only raise
5461 fatal errors when `make -j' is involved. Improve error message.
5463 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5465 * doc/autoconf.texi (Here-Documents): We now know more about
5466 the variable expansion in here documents bug.
5467 Thanks to Tim Rice and Stepan Kasal.
5469 * doc/autoconf.texi (Making testsuite Scripts): Add an example
5470 how to use TESTSUITEFLAGS. Suggested by Eric Blake.
5472 2006-05-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5474 * tests/autotest.at (Multiline command from M4 expansion):
5475 No failure to be expected if the shell quotes newlines in
5476 commands in the `set -x' output. Report by Tim Rice.
5479 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
5481 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Don't use shell
5482 expansion in the here-documents used by config.status, as that
5483 runs afoul of the Korn shell version M-12/28/93d bug described in
5484 the Autoconf manual, and this in turn causes a Coreutils 5.95 build to
5485 fail as described by Tim Rice and diagnosed by Ralf Wildenhues in
5486 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00082.html>.
5488 2006-05-23 Jim Meyering <jim@meyering.net>
5490 * lib/autoconf/functions.m4 (AC_FUNC_LSTAT_FOLLOWS_SLASHED_SYMLINK):
5491 Fix typo introduced with 2006-04-02 change. It reversed the sense
5494 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
5496 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Simplify ac_dA and
5497 ac_dB slightly, to save bytes in the script.
5498 Max out at 50 lines, rather than 96; this is more likely
5499 (though not guaranteed) to avoid obscure 'sed' failures.
5501 2006-05-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5503 * lib/autotest/general.m4 (AT_INIT): UnixWare `tr' may interpret
5504 `tr -d -' as bad option argument. Work around this by deleting
5505 an unrelated character.
5506 Report by Tim Rice <tim@multitalents.net>.
5508 2006-05-22 Paul Eggert <eggert@cs.ucla.edu>,
5509 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
5510 Stepan Kasal <kasal@ucw.cz>
5512 * doc/autoconf.texi (Particular Programs): Do not promise that
5513 we always prefer the GNU version of the program, and that we
5514 search according to PATH; both rules can have exceptions.
5515 Update description of AC_PROG_GREP, AC_PROG_EGREP, AC_PROG_FGREP,
5516 AC_PROG_SED. Move descriptions of limitations
5517 to the Limitations of Usual Tools section.
5518 (Limitations of Usual Tools) <sed>: Mention script length
5519 limitations with Solaris /usr/ucb/sed.
5520 <grep>: Fix wording for empty alternative. Mention that -c and
5521 -l should not be combined, and that -E and -F should not be
5524 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
5525 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5527 * lib/autoconf/programs.m4 (AC_PROG_SED): Catch script length
5528 limits in Solaris 8 /usr/ucb/sed by testing a long script.
5530 2006-05-22 Stepan Kasal <kasal@ucw.cz>
5532 * doc/autoconf.texi (Defining Symbols): Literal parameter of
5533 AC_DEFINE is now passed to m4_pattern_allow.
5534 * NEWS: Mention that; likewise for AC_SUBST.
5535 * lib/autoconf/general.m4 (AC_DEFINE_TRACE_LITERAL): Pass
5536 the parameter to m4_pattern_allow.
5537 * tests/tools.at: Add a check for that.
5539 2006-05-22 Stepan Kasal <kasal@ucw.cz>
5541 * lib/autoconf/status.m4: Fix typos.
5543 2006-05-21 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5545 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Remove
5546 only the files that this macro generates.
5548 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
5550 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: For
5551 the HP-UX sed limitation of 99 commands, labels do not count.
5552 * lib/autoconf/status.m4 (_AC_SED_CMD_LIMIT): Mention that
5554 (_AC_OUTPUT_HEADER): Revert the change from 2006-05-19.
5556 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
5558 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT):
5559 Import the following fix from coreutils:
5561 2006-01-13 Jim Meyering <jim@meyering.net>
5563 Invoke AC_CHECK_FUNCS(getmntent) unconditionally so that tests of
5564 $ac_cv_func_getmntent (e.g., in gl_LIST_MOUNTED_FILE_SYSTEMS) need
5565 not double-quote uses of that variable, to accommodate the rare
5566 case in which getmntent is available in none of the libraries
5567 checked. This happens at least on FreeBSD 5.0.
5569 2006-05-20 Paul Eggert <eggert@cs.ucla.edu>
5571 * lib/autoconf/general.m4 (AC_CONFIG_AUX_DIRS): Bring back
5572 ac_config_guess, ac_config_sub, and ac_configure, since evidently
5573 some other programs unwisely rely on these undocumented vars.
5574 But put in warning comments about them.
5575 Problem reported by Ralf Wildenhues in
5576 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00068.html>.
5577 * NEWS: Document that these variables are intended to go away.
5579 2006-05-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5581 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): Require AC_PROG_CXX,
5582 and set the language to C++ (analogous to the equivalent Fortran
5585 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): New macro.
5586 * doc/autoconf.texi (C++ Compiler): Document it.
5587 * lib/autoconf/fortran.m4 (_AC_PROG_FC_C_O): Adjust comment.
5590 2006-05-19 Paul Eggert <eggert@cs.ucla.edu>
5592 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Fix off-by-one bug
5593 that caused config.status to generate 100-command sed scripts; the
5594 portable limit is 99.
5596 2006-05-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5598 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Name temporary
5599 variable `ac_d' instead of `d' to avoid infringing namespace.
5600 Report by Ralf Menzel.
5602 2006-05-18 Paul Eggert <eggert@cs.ucla.edu>
5604 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Don't prepend
5605 $ac_top_build_prefix to $MKDIR_P if it's just 'mkdir -p'.
5606 * tests/tools.at (autoconf: subdirectories): New test, taken from
5607 the corresponding problem report by Ralf Wildenhues in:
5608 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00053.html
5610 * lib/autoconf/functions.m4 (AC_REPLACE_FNMATCH, AC_FUNC_FNMATCH_GNU):
5611 Quote some uses of shell variables if they might suffer unexpected
5612 globbing. This doesn't fix all instances of quoting problems that
5613 I found, just the easy ones that look safe.
5614 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR, _AC_INIT_HELP):
5615 (AC_CONFIG_AUX_DIR, AC_CONFIG_AUX_DIR_DEFAULT, AC_CONFIG_AUX_DIRS):
5616 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST, AC_CANONICAL_TARGET):
5617 (AC_CACHE_LOAD, AC_CACHE_SAVE): Likewise.
5618 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF, _AC_PATH_X_DIRECT): Likewise.
5619 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Likewise.
5620 * lib/autoconf/status.m4 (_AC_OUTPUT_LINK, _AC_OUTPUT_SUBDIRS):
5622 * lib/autotest/general.m4 (_AC_INIT_PARSE_ARGS): Likewise.
5623 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Likewise.
5625 2006-05-18 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5627 * bin/autoreconf.in ($help): Reword according to the manual.
5628 Suggested by Olly Betts.
5630 2006-05-17 Olly Betts <olly@survex.com> (tiny change)
5631 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5633 * bin/autoreconf.in: Pass the directory argument to
5634 `require_configure_ac'. Fix comment.
5635 * tests/torture.at (Configuring subdirectories): Expose this.
5636 Reported by Olly Betts.
5638 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5640 * lib/Automake/Configure_ac.pm, lib/Automake/Channels.pm,
5641 lib/Automake/FileUtils.pm, lib/Automake/Struct.pm: Sync from
5642 Automake as follows:
5644 * lib/Autom4te/Configure_ac.pm (find_configure_ac): Use
5645 `$configure_in' instead of `configure.in', to preserve
5646 directory component.
5648 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5650 * config/config.guess, config/config.sub, config/texinfo.tex,
5651 doc/make-stds.texi, doc/standards.texi: Sync from upstream.
5653 2006-05-14 Paul Eggert <eggert@cs.ucla.edu>
5655 * lib/autoconf/headers.m4 (AC_HEADER_STDBOOL): Fix overly-picky
5656 test for C99 conformance; (bool) 0.5 is an integer constant
5657 expression, but (bool) -0.5 is not. Problem reported by Fedor
5658 Sergeev in <http://forum.sun.com/jive/thread.jspa?threadID=96202>.
5660 2006-05-13 Paul Eggert <eggert@cs.ucla.edu>
5662 * doc/autoconf.texi (Particular Programs): AC_PROG_MKDIR_P now
5663 sets MKDIR_P, not mkdir_p, to avoid collisions with Automake.
5664 Warn about obsolete install-sh files. Remove stray sentence
5665 fragment and fix cross reference.
5666 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Don't insist on
5667 install -d; this undoes the 2006-05-10 change.
5668 (MKDIR_P): Mark with AN_MAKEVAR.
5669 (AC_PROG_MKDIR_P): Fall back on $ac_install_sh, not $INSTALL, so
5670 that we don't require $INSTALL to be thread-safe. Move comments
5671 out of generated code. Require AC_CONFIG_AUX_DIR_DEFAULT instead
5672 of AC_PROG_INSTALL. Output a message saying that we're checking
5673 mkdir -p. Set MKDIR_P rather than mkdir_p. Do special magic for
5674 MKDIR_P instead of AC_SUBST.
5675 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE, _AC_OUTPUT_CONFIG_STATUS):
5676 Special magic for MKDIR_P, too.
5677 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Remove comment that defeated
5679 * tests/local.at (AT_CHECK_ENV): mkdir_p -> MKDIR_P.
5681 2006-05-11 Paul Eggert <eggert@cs.ucla.edu>
5683 Sync from Automake, as follows:
5685 2006-05-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5686 * config/install-sh: Initialize IFS, so field splitting isn't
5688 * config/mkinstalldirs: Likewise.
5689 * config/missing: Remove superfluous quotes. Replace all uses of
5690 `[' by `test', for consistency, and for..
5691 * config/missing (sed_minuso, sed_output): New variables.
5692 (autom4te, help2man, makeinfo): Use them. Unifies detection of
5693 `-o FILE', `--output FILE', `--output=FILE', stricter regex.
5694 Fixes `missing' to detect `--output' for help2man. Fixes
5695 PR automake/483. Report by Dennis J. Linse.
5696 (autom4te): Document in `missing --help'.
5698 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
5700 * NEWS: New macro AC_PROG_MKDIR_P. AS_MKDIR_P is now more robust.
5701 * config/install-sh: Don't use 'path' to talk about file names,
5702 as per GNU coding standards. Close a race condition reported by Ralf
5703 Wildenhues and Stepan Kasal. There is still a race condition
5704 on hosts that predate Posix 1003.1-1992, but we can't help this.
5705 Don't mishandle weird characters like space on pre-Posix hosts.
5706 Invoke mkdir at most once per dir arg on pre-Posix hosts.
5707 * doc/autoconf.texi (Programming in M4sh): Cross-reference to
5708 AC_PROG_MKDIR_P from AS_MKDIR_P.
5709 (Limitations of Usual Tools): Cross-reference to AC_PROG_MKDIR_P
5710 from mkdir. Mention that Autoconf 2.60 install-sh is safe but
5711 earlier editions are not (including Automake 1.8.3).
5712 Do not suggest mkinstalldirs for thread-safety.
5713 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Insist on an 'install'
5714 that understands -d, so that AC_PROG_MKDIR_P can fall back on $INSTALL.
5715 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Make it more robust in the
5716 presence of special characters and race conditions.
5717 * tests/local.at (AT_CHECK_ENV): Add mkdir_p to the list of variables
5718 in Autoconf's name space.
5720 2006-05-10 Bruno Haible <bruno@clisp.org>
5721 and Paul Eggert <eggert@cs.ucla.edu>
5723 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): New macro, taken
5724 from Automake with minor changes.
5725 * doc/autoconf.texi (Particular Programs): Document AC_PROG_MKDIR_P.
5727 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
5729 * config/install-sh: Update to Automake CVS version, as follows:
5730 2006-04-25 Stepan Kasal <kasal@ucw.cz>
5731 * lib/install-sh: Simplify the expr implementation of dirname.
5732 2006-04-24 Paul Eggert <eggert@cs.ucla.edu>
5733 * lib/install-sh: Handle --, and diagnose unknown options.
5735 2006-05-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5737 * tests/Makefile.am (AUTOTEST): Use `$(MY_AUTOM4TE)' instead of
5738 `./autom4te' to create `./testsuite', since the `all' target
5739 will ensure its presence, but `installcheck' should not create
5740 the uninstalled wrappers.
5742 * tests/torture.at (Unusual Automake input files): Skip if we
5743 detect automake < 1.8.
5745 2006-05-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5747 * lib/autoconf/c.m4 (AC_PROG_CC_STDC): If ac_cv_prog_cc_stdc
5748 is set to `no', then that overrides and sets ac_cv_prog_cc_c89
5749 and ac_cv_prog_cc_c99 to `no', for backward compatibility.
5752 2006-05-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5754 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Take care not to
5755 munge (multiple) white space and other oddities.
5756 * tests/torture.at (AT_CHECK_AC_ARG_VAR): Make sure to M4-escape
5757 single quotes in variable assignment.
5758 (AC_ARG_VAR, configure invocation): Adjust tests to expose this
5759 and similar failures by adding multiple spaces, tabs, and other
5761 Report and different test suggested by Francesco Romani
5762 <fromani@gmail.com> and Andrew Church <achurch@achurch.org>.
5764 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): When we escape
5765 single quotes, we only need to search for single quotes; this
5766 both simplifies the search pattern, and makes us less
5767 susceptible to `echo' variations for arguments not containing
5769 (_AC_ARG_VAR_VALIDATE): Likewise.

5857 2006-04-25 Paul Eggert <eggert@cs.ucla.edu>
5859 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Don't use AS_ERROR,
5860 since as_me isn't set yet.
5862 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
5864 Prepare for deprecation of AS_BASENAME and AS_DIRNAME, and fix
5865 a few minor bugs in this area.
5867 * doc/autoconf.texi (Programming in M4sh): Comment out the
5868 documentation of AS_BASENAME, for now.
5869 (Shell Substitutions): Do not use AS_DIRNAME in an example.
5870 (Limitations of Builtins) <basename>: Do not refer to

5898 with more accuracy and detail.
5900 2006-04-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5902 * doc/autoconf.texi (Introduction): The GNU Autoconf Macro
5903 Archive is not officially `GNU' any more. Update URL.
5904 (Defining Directories): Likewise
5905 * lib/autoconf/c.m4 (AC_C_RESTRICT): Update URL.
5907 2006-04-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5909 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Remove the leading
5910 newline from the `trap' code to finish `config.log'; the NetBSD
5911 /bin/sh resets the exit status after an empty command, as
5912 documented in doc/autoconf.texi.
5913 Reported by Dalibor Topic <robilad@kaffe.org>.
5915 2006-04-19 Paul Eggert <eggert@cs.ucla.edu>
5917 * doc/autoconf.texi (C Compiler): Clarify AC_C_TYPEOF.
5918 Suggested by Bruno Haible.
5920 2006-04-18 Paul Eggert <eggert@cs.ucla.edu>
5922 * configure.ac (ac_cv_sh_n_works): Don't try to test for it, since
5923 some shells (e.g., Solaris 8 /bin/sh) implement it verrrry slowly.
5924 Instead, just list the shells that we know work.
5925 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Remove 2nd arg. All uses
5926 changed. Be more cautious about the _cv_ variable.
5927 * tests/tools.at (Syntax of the shell scripts): Check the
5928 _cv_ variable once, at first, to avoid an internal autoconf error
5929 when sh -n does not work.
5931 2006-04-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5933 * lib/Autom4te/FileUtils.pm: Sync from Automake.
5935 2006-04-16 Paul Eggert <eggert@cs.ucla.edu>
5937 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Don't
5938 use ">&-" since we're only 99.999% sure that this is portable,
5939 and since the MinGW bug is fixed in a different way.
5940 * lib/autotest/general.m4 (AT_INIT): Likewise.
5942 2006-04-16 Stepan Kasal <kasal@ucw.cz>
5944 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Handle --recheck
5945 before opening config.log, to avoid hitting a bug on MinGW.
5947 2006-04-14 Paul Eggert <eggert@cs.ucla.edu>
5949 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Close
5950 AS_MESSAGE_LOG_FD before reopening it onto the log file.
5951 This works around a MinGW bug reported by Eric Paire.
5952 Make sure that all writes to the log file append to it,
5953 rather than possibly losing data.
5954 * lib/autotest/general.m4 (AT_INIT): Likewise.
5956 2006-04-14 Stepan Kasal <kasal@ucw.cz>
5958 * lib/Autom4te/FileUtils.pm (find_file): Fix a typo in the
5961 2006-04-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5965 * configure.ac (AC_INIT): Bump to 2.59d.
5967 2006-04-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5971 * Makefile.maint (news-date-check): Do not require a leading `*'
5972 before the release date in NEWS.
5974 2006-04-12 Stepan Kasal <kasal@ucw.cz>
5975 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5977 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If the templates for
5978 the instantiated file do not contain the string 'datarootdir'
5979 but contain @datadir@, @docdir@, @infodir@, @localedir@, or
5980 @mandir@, replace the reference '${datarootdir}' by the value.
5981 * tests/torture.at (datarootdir workaround): New test.
5982 * NEWS: Advertise this temporary fixup.
5983 Based on a patch by Bruno Haible, reported and analyzed by
5984 Paul Eggert and Noah Misch.
5986 2006-04-12 Eric Blake <ebb9@byu.net>
5988 * tests/autotest.at (Debugging a failed test): Fix comment.
5990 2006-04-12 Stepan Kasal <kasal@ucw.cz>
5992 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): Simplify the summary of
5993 all the changes since 2006-04-07.
5995 2006-04-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5997 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): If `ln -s file1 file2'
5998 succeeded, but `ln -s file dir' failed, take care to remove the
5999 leftover target before the next test, to prevent its spurious
6000 failure; also make sure `ln file dir' works before selecting it.
6001 Thanks to Keith Marshall for pointing this out.
6004 * lib/autotest/general.m4 (AT_INIT): Store quoted variable
6005 assignments in `at_debug_args', so that we put them correctly
6006 in the `run' script.
6007 * tests/autotest.at (Debugging a failed test): Unmark XFAIL.
6008 Reported by Eric Blake.
6010 2006-04-11 Eric Blake <ebb9@byu.net>
6012 * tests/autotest.at (AT_CHECK_AT): Add new argument, to allow
6013 top-level tests after micro-suite has been run. Used in...
6014 (Debugging a successful test, Debugging script and environment),
6015 (Debugging a failed test): ...these new tests. The first of these
6017 * lib/autotest/general.m4 (_AT_CREATE_DEBUGGING_SCRIPT): New
6018 macro, split out from...
6019 (AT_INIT): ...here, so that using -d also generates a run script.
6020 Document that -d inhibits top-level logging.
6021 * doc/autoconf.texi (testsuite Invocation): Document that -d only
6022 inhibits top-level logging; debug scripts are created.
6024 * lib/autotest/general.m4 (_AT_CHECK): Avoid syntax error on empty
6026 * tests/autotest.at (Empty test, Empty check): New test to check it.
6028 * lib/autoconf/c.m4 (AC_C_CONST, AC_C_VOLATILE): Avoid warnings
6031 2006-04-10 Stepan Kasal <kasal@ucw.cz>
6033 * tests/mktests.sh: Use "trap '' 0", not "trap 0". Do not touch
6034 the files if a problem appears. Make the empty *.at files
6035 read-only, too. Proposed by Ralf Wildenhues.
6037 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6039 * config/Makefile.am: Add comment to force updated Makefile.in.
6041 * lib/freeze.mk: Fix typo in comment. Unlike the last, white
6042 space only patch to this file, this patch causes the Makefile.in
6043 files that include freeze.mk to be updated, and thus have a
6044 newer time stamp again, which in turn makes a pristine CVS
6045 checkout have correct time stamps.
6047 * Makefile.maint (cvs-sv): New macro, to be used..
6048 (config.guess-url_prefix, config.sub-url_prefix)
6049 (texinfo.tex-url_prefix, standards.texi-url_prefix): ..here;
6050 point to CVS text checkout of Gnulib files.
6051 (copyright-check): Bump current year.
6052 (announcement): Do not hard-wire `./announce-gen'.
6053 (cvs-update): Propagate failures of `cvs' and `move-if-change'
6055 * Makefile.cfg (executable-update): Use `chmod a+x' instead of
6057 (wget_files): Update config.guess, config.sub, texinfo.tex by
6058 `wget-update', now that their URLs work again.
6060 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
6062 * doc/autoconf.texi (Particular Types): Don't use AC_CHECK_TYPE.
6063 Problem noted by Paul D. Smith.
6065 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6067 * doc/autoconf.texi: Remove unused words from word list.
6068 * .x-sc_prohibit_atoi_atof, .x-sc_space_tab, .x-sc_sun_os_names,
6069 .x-sc_trailing_space: New files.
6071 * doc/standards.texi: Sync from gnulib.
6073 * NEWS, doc/autoconf.texi (AC_LIBOBJ vs LIBOBJS): Mark
6074 `LIBOBJDIR' as experimental.
6076 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): MSYS `ln -s' fails
6077 with a target directory; it's internally implemented as `cp'
6078 anyway, but since Autoconf advertises the possibility to use
6079 a target directory when LN_S is `ln -s', we need to find out.
6080 Reported by Rolf Ebert <rolf.ebert.gcc@gmx.de> against MSYS,
6081 analyzed by Keith Marshall <keith.marshall@total.com>.
6085 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
6087 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Just output
6088 confdefs.h as-is. In general, if it has backslash-newline or the
6089 like, then it doesn't work either to sort or to remove empty
6092 2006-04-09 Stepan Kasal <kasal@ucw.cz>
6094 * tests/Makefile.am (AUTOCONF_FILES): Fix typo in the comment.
6096 2006-04-09 Alexandre Duret-Lutz <adl@gnu.org>
6098 * lib/autom4te.in (Automake-preselections): Preselect
6101 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>
6103 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Use '\'' for an
6104 apostrophe within a single-quoted string, as this is the usual
6105 tradition and is easier to read than '"'"'. Don't rely on the
6106 shell treating "$/" like '$/'. Use a more-consistent indenting
6109 2006-04-09 Eric Blake <ebb9@byu.net>
6111 * tests/autotest.at (Backquote command substitution),
6112 (Multiline backquote command substitution): Remove mistaken
6113 AT_NO_CMDSUBST from the 2006-03-14 patch, which was meant to be
6115 (Parenthetical command substitution, Multiline parenthetical
6116 command substitution): here.
6118 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>

6151 AC_TYPE_UINTMAX_T, AC_TYPE_UINTPTR_T, AC_TYPE_UNSIGNED_LONG_LONG_INT.
6152 (C Compiler): Move AC_C_LONG_DOUBLE to ...
6153 (Obsolete Macros): here. Under AC_LONG_DOUBLE, mention

6193 2006-04-07 Stepan Kasal <kasal@ucw.cz>
6195 Revert the patch from 2006-04-01 and only improve
6196 _AS_DETECT_BETTER_SHELL:
6198 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Do not optimize; do not
6199 skip nonexistent directories.
6200 (_AS_DETECT_BETTER_SHELL): The optimization is moved here--try
6201 only shell candidates which exist.
6202 (AS_UNAME): No need to give three parameters to _AS_PATH_WALK.
6203 * lib/autotest/general.m4 (AT_INIT): No need to give three

6249 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6251 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): Fix the detection of
6252 whether `set' quotes correctly: redirect stderr of the tested
6253 `set', and use a subshell, for Ultrix; use `sed' instead of
6254 `grep' for zsh `set' which may write binary output; match only
6255 at the beginning of a line, to avoid false positives.
6256 In order to avoid false positives by unrelated variables with
6257 multiline content, put the dump algorithm in a subshell and
6258 unset all variables containing newlines (except some which are
6259 special to the shell). Warn about cache variables that are

6308 (_AC_CONFIG_REGISTER_DEST): Double quote the tags in macros _AC_LIST_TAGS
6309 and_AC_LIST_TAG_COMMANDS; fixes another regression introduced by the

6320 for --help from Cygnus `configure.'
6322 2006-04-06 Paul Eggert <eggert@cs.ucla.edu>

6379 (exclude_list): Exclude empty macros.
6380 (ac_exclude_list): Exclude AC_INCLUDES_DEFAULT.

7173 Suggest passing CONFIG_SHELL absolute, and in the environment
7174 rather than as option.
7176 2005-11-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7178 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE):
7179 Fix quoting of output line (triggered for many AC_SUBST_FILEs).
7180 Fix macro quoting. Fix output for n * 98 substituted variables.
7182 2005-11-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7184 * lib/autoconf/status.m4 (_AC_OUTPUT_MAIN_LOOP): Initialize

7187 2005-11-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7189 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Initialize
7190 ac_clean_files and LIBOBJS.
7192 2005-11-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7194 * lib/autoconf/programs.m4 (AC_CHECK_PROG, AC_PATH_PROG):
7195 Factor functionality to..
7196 (_AC_CHECK_PROG, _AC_PATH_PROG): these new macros, but only
7197 `AC_SUBST($1)' in the public version.
7198 (AC_CHECK_TOOL, AC_PATH_TOOL, AC_PATH_TARGET_TOOL)
7199 (AC_CHECK_TARGET_TOOL): Use internal versions for ac_ct_* and
7202 2005-11-01 Stepan Kasal <kasal@ucw.cz>
7204 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Remove the comment about 8+3
7207 2005-11-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7209 * NEWS: Move AH_HEADER mention to right place.
7211 2005-10-27 Stepan Kasal <kasal@ucw.cz>
7213 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): "conftst2" -> "conftest2"
7214 * lib/autoconf/fortran.m4 (_AC_PROG_FC_C_O): Likewise.
7216 2005-10-25 Stepan Kasal <kasal@ucw.cz>
7218 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): rm -f conftst2.*, not only
7219 conftst2.$ac_objext.
7220 * lib/autoconf/fortran.m4 (_AC_PROG_FC_C_O): Likewise.
7222 2005-10-24 Stepan Kasal <kasal@ucw.cz>
7224 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Use conftst2.o instead of
7225 conftest.o, to see whether the compiler really obeys; rm the object
7226 file before and after the test and register it with ac_clean_files.
7227 * lib/autoconf/fortran.m4 (_AC_PROG_FC_C_O): Likewise.
7229 2005-10-21 Stepan Kasal <kasal@ucw.cz>
7231 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): When determining,
7232 the delimiter CEOF$ac_eof: fix quoting of CEOF[0-9]* and modify the
7233 code so that the most common case requires less forks.
7235 2005-10-20 Stepan Kasal <kasal@ucw.cz>
7237 * doc/autoconf.texi (Shell Substitutions}: Document that ${10} is
7238 not portable; thanks to Paul Eggert and Alexandre.
7240 * NEWS: Fix an old typo.
7242 2005-10-20 Jim Meyering <jim@meyering.net>
7244 * doc/autoconf.texi: Typo: s/feature/features/ in ``the features of
7245 the latter'', in two places.
7247 2005-10-19 Paul Eggert <eggert@cs.ucla.edu>
7249 * doc/autoconf.texi (Generating Sources): AC_LANG_PROGRAMS ->
7250 AC_LANG_PROGRAM, fixing a typo. Don't give details about
7251 the inner workings of AC_LANG_FUNC_LINK_TRY.
7252 * lib/autoconf/c.m4 (AC_LANG_CALL(C)): Reformat to match
7253 AC_LANG_FUNC_LINK_TRY. This involves returning the value returned
7254 by the function rather than ignoring it.
7255 (AC_LANG_FUNC_LINK_TRY(C)): Call the function rather than simply
7256 comparing its address. Intel's interprocedural optimization was
7257 outsmarting the old heuristic. Problem reported by
7260 2005-10-19 Stepan Kasal <kasal@ucw.cz>
7262 * lib/autoconf/general.m4 (AC_SUBST): Remove an obsolete comment.
7264 2005-10-05 Paul Eggert <eggert@cs.ucla.edu>
7266 * lib/m4sugar/m4sugar.m4 (_m4_map): New macro.
7267 (m4_map, m4_map_sep): Use it. Handle the empty list correctly.
7269 2005-10-04 Stepan Kasal <kasal@ucw.cz>
7271 * lib/autotest/general.m4 (AT_INIT): Really make the subtree writable
7272 before removing it (chmod -R u+rwx); there are three instances of this.
7274 2005-10-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7275 Stepan Kasal <kasal@ucw.cz>
7277 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Balance parentheses.
7278 * lib/autotest/general.m4 (AT_INIT): If the test dir already exists,
7279 make its content writable before removing it. Remove an errorneous
7280 comment from the end, where the logs of the failed tests are copied
7281 to the main log file.
7283 2005-09-27 Stepan Kasal <kasal@ucw.cz>
7285 * tests/semantics.at (AC_C_BIGENDIAN): Pass --force to autoheader,
7286 in case the computer is too quick. Double quote the configure.ac
7289 * tests/local.at (AT_CHECK_AUTOCONF): Always pass --force to prevent
7290 problems if the testsuite were running too fast.
7292 2005-09-18 Paul Eggert <eggert@cs.ucla.edu>
7294 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Look for X11/Xlib.h
7295 and XrmInitialize rather than X11/Intrinsic.h and XtMalloc
7296 (which belong to Xt, not X itself). See Debian bug 327655.
7297 * NEWS: Mention this.
7299 2005-09-07 Stepan Kasal <kasal@ucw.cz>
7301 * lib/autoconf/c.m4 (AC_LANG_SOURCE(C)): Remove an incorrect comment.
7303 2005-09-06 Paul Eggert <eggert@cs.ucla.edu>
7305 * config/move-if-change: Don't output "$2 is unchanged";
7306 suggested by Ben Elliston. Handle weird characters correctly.
7308 2005-09-06 Stepan Kasal <kasal@ucw.cz>
7310 * lib/autoconf/libs.m4 (AC_SEARCH_LIBS): Merge the two AC_LINK_IFELSE
7311 calls, so that the final expansion of this macro is shorter.
7312 Create the conftest.$ac_ext outside the `for' loop, to speed the run.
7313 Do not use `break' in the argument to AC_LINK_IFELSE, it would skip
7314 the cleanup there. Use AS_VAR_* macros, to be more general.
7315 * tests/semantics.at (AC_SEARCH_LIBS): Check for the cleanup.
7317 * lib/autoconf/general.m4: Use AS_IF where appropriate.
7319 * lib/m4sugar/m4sh.m4 (AS_IF): Use m4_default.
7321 2005-09-01 Stepan Kasal <kasal@ucw.cz>
7323 * doc/autoconf.texi (Configuration Headers): Add an index entry
7326 2005-08-26 Pavel Roskin <proski@gnu.org>
7328 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): Use shell variable
7329 XMKMF to locate xmkmf. Make XMKMF precious. Export CC when
7332 2005-08-26 Paul Eggert <eggert@cs.ucla.edu>
7334 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE):
7335 The previous patch didn't work, so try a better one.
7337 2005-08-26 Stepan Kasal <kasal@ucw.cz>
7339 * doc/autoconf.texi (Programming in M4sh) <AS_TR_CPP>: Fix m4 quoting
7340 in the example. Reported by Bruno Haible.
7341 <AS_TR_SH>: Likewise. Also modify the example to be more convincing:
7342 "if $undefined_var;" succeeds with my shell.
7344 * lib/autoconf/general.m4 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST,
7345 AC_CANONICAL_TARGET): Define by AC_DEFUN, no need to use AC_DEFUN_ONCE;
7346 but change the m4_divert_text to m4_divert_once.
7348 2005-08-25 Paul Eggert <eggert@cs.ucla.edu>
7350 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE):
7351 Work around bug in Solaris /usr/xpg4/bin/awk.
7352 The bug is present in at least Solaris 8 through 10.
7354 2005-08-24 Stepan Kasal <kasal@ucw.cz>
7356 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Simplify; rejecting
7357 some evil values and relying on the fact that $* concatenates the
7358 parameters by the first character from IFS.
7360 2005-08-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
7361 Stepan Kasal <kasal@ucw.cz>
7363 * lib/autoconf/status.m4 (_AC_CONFIG_REGISTER_DEST): When the
7364 first header appears, define AH_HEADER.
7365 * doc/autoconf.texi (Configuration Headers): Document AH_HEADER.
7366 Update limitations about when to call AC_CONFIG_HEADERS.
7367 (Configuration Commands): Document that AC_CONFIG_COMMANDS_PRE
7368 parameter can call AC_SUBST, AC_DEFINE, or AC_CONFIG_FOOS; explain
7369 that AC_CONFIG_COMMANDS_PRE and AC_CONFIG_COMMANDS_POST are not
7370 ``Configuration Actions''; fix their index entries.
7372 * lib/autotest/general.m4 (AT_INIT): Process multiple keywords
7373 options correctly. Process N-M as M-N if M is smaller than N.
7374 Process ranges correctly so that N-N will run only N.
7375 Sort and uniquify the tests that will be run. If there is more
7376 than one test, reinsert the banners for the tests.
7377 * tests/autotest.at (Keywords): Unmark XFAIL.
7379 2005-08-23 Stepan Kasal <kasal@ucw.cz>
7381 * lib/autoconf/general.m4 (_AC_DEFINE_Q): Strip the parameter list
7382 before passing the macro name to AH_TEMPLATE.
7384 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): config.status
7385 now opens log after option processing; in particular, --version
7386 and --help do not touch config.log.
7388 * Makefile.maint: Revert the change from 2005-08-12.
7390 2005-08-22 Stepan Kasal <kasal@ucw.cz>
7392 * lib/autoconf/general.m4 (AC_ARG_ENABLE, AC_ARG_WITH): Factor out

7398 * doc/autoconf.texi (Using Autotest, testsuite Scripts)
7399 (Autotest Logs, Writing testsuite.at, testsuite Invocation):
7402 * doc/autoconf.texi (Defining Symbols, Changed Results):
7403 Prepend to LIBS, not append, in examples.
7405 2005-08-16 Stepan Kasal <kasal@ucw.cz>
7407 When building in place, set srcdir="."; suggested by Tim Van Holder.
7409 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Do this; to recognize
7410 build in place, we need ac_pwd, and thus have to AC_REQUIRE ...
7411 (_AC_INIT_DIRCHECK): ... this macro and AC_DEFUN both of them.
7412 * lib/autoconf/status.m4 (_AC_SRCDIRS): Fix a comment: srcdir="."
7413 does not mean "no --srcdir option".
7415 2005-08-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7417 * tests/autoscan.at (autoscan): New file.
7418 * tests/suite.at: Use it.
7419 * tests/Makefile.am (TESTSUITE_HAND_AT): Add it.
7420 Reported against Libtool by Gideon Go <gideon.go@gmail.com>.
7422 * tests/autotest.at (Keywords): Test keywords combinations.
7424 2005-08-12 Stepan Kasal <kasal@ucw.cz>
7426 * Makefile.maint (GZIP_ENV): When checking the help text of gzip,
7427 add "2>&1"; gzip 1.2.4 prints help on stderr.
7429 2005-07-27 Stepan Kasal <kasal@ucw.cz>
7431 * lib/autotest/general.m4 (_AT_DECIDE_TRACEABLE): The symbol at_reason
7432 was pushdef'ed twice while popped only once. Push it only once.
7433 (_AT_CHECK): Cosmetic changes to the "case $at_status" command.
7435 2005-07-26 Stepan Kasal <kasal@ucw.cz>
7437 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): The message is now
7438 prefixed by mere "===", not "configure: === ".

7442 * Makefile.maint: Update from Bison.
7444 * lib/m4sugar/m4sugar.m4 (m4_strip): Comment fix---change tab to
7445 "<tab>" in comment, so that the point is understandable.
7447 2005-07-25 Stepan Kasal <kasal@ucw.cz>
7449 Rewrite substantial part of lib/autoconf/status.m4.
7450 The main change is that CONFIG_FILES, CONFIG_HEADERS, CONFIG_LINKS,
7451 and CONFIG_COMMANDS are not processed in four separate loops.
7452 Instead, there is one main loop. This alows that the common code
7453 is expanded only once, thus config.status (and configure) is smaller.
7455 The registration mechnism in AC_CONFIG_FILES and cousins also changed;
7456 the AC_LIST_FILES and cousins macros are no longer used.
7458 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES, _AC_OUTPUT_HEADERS,
7459 _AC_OUTPUT_LINKS, _AC_OUTPUT_COMMANDS): Renamed to ...
7460 (_AC_OUTPUT_FILE, _AC_OUTPUT_HEADER, _AC_OUTPUT_LINK,
7461 _AC_OUTPUT_COMMAND): ..., respectively. These macros no longer
7462 contain the initialization, nor the for loop, nor the associated
7463 commands; all these go to ...
7464 (_AC_OUTPUT_MAIN_LOOP): ... this new macro, called from
7465 _AC_OUTPUT_CONFIG_STATUS.
7466 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST, _AC_CONFIG_SPLIT_FILE_IN):
7467 Nuked; the code was merged into _AC_OUTPUT_MAIN_LOOP.
7468 (_AC_OUTPUT_FILE): The creation of the sed script ...
7469 (AC_OUTPUT): ... and the setup of ac_vpsub goes to ...
7470 (_AC_OUTPUT_FILES_PREPARE): ... a new macro, also called from
7471 _AC_OUTPUT_MAIN_LOOP.
7472 (_AC_CONFIG_FILES, _AC_CONFIG_HEADERS, _AC_CONFIG_LINKS,
7473 _AC_CONFIG_COMMANDS): Use ...
7474 (_AC_CONFIG_FOOS): ... this new macro, which uses these ...
7475 (_AC_CONFIG_REGISTER, _AC_CONFIG_REGISTER_DEST): ... new macros.
7476 (_AC_CONFIG_FILE, _AC_CONFIG_HEADER, _AC_CONFIG_LINK,
7477 _AC_CONFIG_COMMAND, _AC_CONFIG_DEPENDENCIES): No longer needed.
7478 (_AC_CONFIG_DEPENDENCY): Update, it uses these ...
7479 (_AC_CONFIG_DEPENDENCY_DEFAULT, _AC_FILE_DEPENDENCY_TRACE_COLON):
7481 (_AC_CONFIG_UNIQUE): Update.
7482 (AC_LIST_FILES, AC_LIST_HEADERS, AC_LIST_LINKS, AC_LIST_COMMANDS):
7483 Replaced by this ...
7484 (_AC_LIST_TAGS): ... new common macro.
7485 (AC_LIST_FILE_COMMANDS, AC_LIST_HEADER_COMMANDS, AC_LIST_LINK_COMMANDS,
7486 AC_LIST_COMMAND_COMMANDS): Replaced by this ...
7487 (_AC_LIST_TAG_COMMANDS): ... new common macro.
7488 (_AC_CONFIG_COMMANDS_INIT): Moved top to the `registration' section;
7489 this didn't belong to the `config commands' section.
7490 (_AC_OUTPUT_COMMANDS_INIT): Don't initialize, m4_ifdef is our friend.
7491 (AC_CONFIG_COMMANDS_PRE, AC_OUTPUT_COMMANDS_PRE,
7492 AC_CONFIG_COMMANDS_POST): Moved to a new section, these didn't belong
7493 to the `config commands' section either.
7494 (AC_CONFIG_SUBDIRS): Don't touch diversion DEFAULTS.
7495 (_AC_LIST_SUBDIRS): Don't initialize, m4_ifdef is our friend.
7497 ... and many changes to the comments nearby.
7499 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): At the end of the day,
7500 set ac_subdirs_all='_AC_LIST_SUBDIRS'.
7501 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
7502 AC_CONFIG_COMMANDS(command:input,...) is no longer allowed.
7503 (#define header templates): The comment at the top of the generated
7504 header now includes the name(s) of the source file(s).
7506 Several unrelated small changes:
7508 * lib/autoconf/general.m4 (AC_CACHE_VAL): Be didactic, quote the first
7509 parameter to AC_DIAGNOSE.
7510 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS): Likewise.
7511 (_AC_LINK_FILES_CNT): Don't AU_DEFUN this; it causes confusing messages
7512 with autoupdate; use m4_define_default inside AU_DEFUNed AC_LINK_FILES.
7513 (AC_OUTPUT): In the compatibility code, use m4_ifvaln, to be consistent
7515 (AU::AC_OUTPUT): Don't double-quote $2 and $3, the compatibility code
7516 in AC_OUTPUT doesn't double-quote it either.
7517 * tests/tools.at (autoupdate): AU::AC_OUTPUT no longer double-quotes the
7520 2005-07-10 Stepan Kasal <kasal@ucw.cz>
7522 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Document which
7523 versions of Portland Group compiler produce single- and double-quoted
7524 -cmdline argument. Reported by Steven G. Johnson <stevenj@fftw.org>
7525 and Ole Holm Nielsen <Ole.H.Nielsen@fysik.dtu.dk>.
7527 2005-07-07 Paul Eggert <eggert@cs.ucla.edu>
7529 * tests/local.at (AT_CONFIG_CMP): Ignore lines like "LIBS=''" too.
7530 This is a corrected version of yesterday's patch.
7532 2005-07-07 Stepan Kasal <kasal@ucw.cz>
7534 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Report the full
7535 path, too; insert a "===" to emphasize the line.
7537 * lib/autoconf/general.m4 (AC_CANONICAL_BUILD): Rename
7538 ac_cv_build_alias to ac_build_alias.
7539 (AC_CANONICAL_HOST, AC_CANONICAL_TARGET): Simplify.
7541 On 2005-02-24, an unintentional AC_SUBST([CC]) was introduced; this
7542 change eliminates it. Problem reported by Alexandre Duret-Lutz.
7543 * lib/autoconf/general.m4 (_AC_ARG_VAR_PRECIOUS): Move the AC_SUBST ...
7544 (AC_ARG_VAR): ... here.
7545 (_AC_INIT_PREPARE): Call AC_SUBST for build_alias, host_alias and
7548 Keep a list of all precious variables and process them with one simple
7549 for loop, instead of expanding all commands, or, OTOH, complicated
7550 processing of output of "set".
7551 * lib/autoconf/general.m4 (_AC_ARG_VAR_PRECIOUS): Acumulate the
7552 variable names in new macro...
7553 (_AC_PRECIOUS_VARS): ... which will be assigned to ac_precious_vars.
7554 (_AC_ARG_VAR_STORE): New macro which writes to diversion PARSE_ARGS
7555 a loop to assign all ac_env_* and ac_cv_env_* variables.
7556 (_AC_ARG_VAR_VALIDATE): Use shell variable ac_precious_vars, divert
7558 (_AC_INIT_DEFAULTS): At the end, if _AC_PRECIOUS_VARS is set, assign
7559 its value to shell variable ac_precious_vars and call
7560 _AC_ARG_VAR_STORE and _AC_ARG_VAR_VALIDATE.
7561 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Don't call
7562 _AC_ARG_VAR_VALIDATE.
7564 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Move AC_LANG_PUSH(C)
7565 and the AC_SUBSTs ...

7569 the ac_subst_files section in config.log.

7583 They are generated by the Tru64 v5.1B shell.
7585 2005-07-05 Stepan Kasal <kasal@ucw.cz>
7587 Fix my changes from 2005-07-01; reported by Noah Misch.
7588 * lib/autoconf/status.m4 (_AC_CONFIG_DEPENDENCIES): Fix the
7589 description, the macro now accepts only a single tag.
7590 (_AC_CONFIG_UNIQUE): Likewise; s/AC_File/[$1]/
7592 Fix cases when the varsions of Autoconf and Autotest don't match.
7593 Reported by Noah Misch.
7594 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Set also
7595 at_top_builddir, for compatibility with older autotest.
7596 * lib/autotest/general.m4 (AT_INIT): If at_top_build_prefix
7597 is not set, use at_top_builddir, for compatibility with older
7598 versions of autoconf.
7600 2005-07-04 Paul Eggert <eggert@cs.ucla.edu>
7602 * bin/autom4te.in ($m4): Catch usages like --nesting-limit=2048.
7603 Problem reported by Patrick Welche.
7605 2005-07-03 Paul Eggert <eggert@cs.ucla.edu>
7607 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Use &, not |, in
7608 sed substitution command, so that we allow | in program prefixes
7609 and program suffixes. (& is a problem anyway; we're not fixing
7611 * lib/autoconf/status.m4 (AC_CONFIG_FILES): Likewise, for
7612 configure_input, top_builddir, srcdir, etc.
7613 * lib/autotest/general.m4 (AT_INIT): Likewise, for
7614 PATH_SEPARATOR in AUTOTEST_PATH.
7616 2005-07-02 Alexandre Duret-Lutz <adl@gnu.org>
7618 * lib/autoconf/general.m4 (AC_SITE_LOAD): Rewrite the
7619 for loop over config.site files using `set', to allow
7620 directory names containing IFS characters.
7622 2005-07-01 Paul Eggert <eggert@cs.ucla.edu>
7624 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Remove the tests for
7625 directories with weird names. Apparently some people like living
7626 on the edge. However, improve the test that "pwd" actually does
7627 report a name for the working directory.
7628 * NEWS: Remove the claim that we test for funny chars in dir names.
7630 2005-07-01 Stepan Kasal <kasal@ucw.cz>
7632 * lib/autoconf/general.m4 (AC_FOREACH): Make obsolete; it's

7672 * lib/autoconf/general.m4 (AC_ARG_VAR): Move next to _AC_ARG_PRECIOUS.
7674 * lib/autoconf/general.m4 (AC_SUBST_TRACE): New macro, to be traced
7675 instead of AC_SUBST; proposed by Alexandre Duret-Lutz.
7676 (AC_SUBST): Call it.
7677 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Call AC_SUBST_TRACE for
7678 the directory specific variables; but don't call it for configure_input.
7680 2005-06-28 Derek Price <derek@ximbiot.com>
7682 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: Reword recent
7685 2005-06-23 Paul Eggert <eggert@cs.ucla.edu>
7687 * NEWS: Don't worry about spaces in bindir etc. Only srcdir and working

7704 from Justace Clutter.
7705 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Put name of invalid
7706 variable into diagnostic. Make the diagnostic an error, not a warning,
7707 because we really don't support spaces and suchlike in dir names.
7708 (_AC_INIT_SRCDIR): Allow special characters in $ac_unique_file.
7709 Don't worry about backslashes in srcdir; it can't happen now.
7710 (_AC_INIT_PARSE_ARGS): Allow weird characters in ac_optarg.
7711 Simplify ac_optarg handling.

7720 (AT_CONFIG_CMP): Use sed instead of grep plumbing.
7722 * doc/autoconf.texi (Limitations of Usual Tools) <grep>: Mention
7723 that '\|' is not allowed in BREs; recommend using newline separated
7724 list of patterns instead of multiple -e options.
7726 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Remove an old comment.
7728 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Use AC_SUBST/2.

7736 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: Document that
7737 b, t, r, w commands require single space, while : cannot have any.
7738 (Special Shell Variables): Fix sed code this in the example.
7739 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Likewise; and fix a typo.
7740 * lib/autotest/general.m4 (AT_ARG_OPTION): Fix typo in the description.
7742 * lib/m4sugar/m4sugar.m4 (m4_split): If the parameter is empty,

7748 * lib/m4/programs.m4 (AC_PROG_YACC): Declare YACC & YFLAGS precious.
7750 2005-06-17 Paul Eggert <eggert@cs.ucla.edu>
7752 * lib/m4sugar/m4sh.m4 (as_awk_strverscmp): Port to Solaris /bin/awk.
7753 * doc/autoconf.texi:
7754 Don't mention Solaris versions so much, if a
7755 problem is common to all extant versions of Solaris. Say "SunOS
7756 4" instead of "SunOS" for SunOS 4.
7757 (awk): Mention more of the limitations of traditional Awk.
7758 (cat): Don't talk about cat -v.

7768 * doc/autoconf.texi (Limitations of Usual Tools): Mention expr bug
7769 on Mac OS X 10.4 reported by Peter O'Gorman in:

7774 2005-06-10 Paul Eggert <eggert@cs.ucla.edu>
7776 * doc/autoconf.texi: "filesystem" -> "file system".
7777 "behaviour" -> "behavior".
7778 Warn about \(...\)* in Solaris sed (written by Ralf Menzel).
7779 * lib/autoconf/general.m4: Omit blank after ":" sed command,
7781 * lib/m4sugar/m4sh.m4: Likewise.
7782 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Work around problem
7783 with Solaris sed. Fix by Ralf Menzel and Stepan Kasal.
7785 * man/Makefile.am (MOSTLYCLEANFILES): Add $(srcdir)/*.t.
7786 (.x.1): Ignore the time stamp in the .TH line when deciding whether

7798 2005-06-08 Paul Eggert <eggert@cs.ucla.edu>
7800 * lib/autotest/general.m4 (AT_INIT): Don't accept Solaris 9's diff
7801 -u, since it outputs chatter if the input files are the same.
7802 Problem reported by Ralf Menzel.
7804 2005-06-08 Derek Price <derek@ximbiot.com>
7806 * lib/m4sugar/m4sugar.m4: Undefine include & sinclude rather than
7807 renaming them since they are about to be redefined anyhow.
7809 2005-06-08 Derek Price <derek@ximbiot.com>
7811 * doc/autoconf.texi (Redefined M4 Macros): Add index entries for most
7812 redefined M4 macros to this node. Document m4_include & m4_sinclude.
7813 Move m4_undefine to alphabetical order.
7815 2005-06-07 Paul Eggert <eggert@cs.ucla.edu>
7817 * README: Recommend GNU M4 1.4.3 or later.
7818 * doc/autoconf.texi (Introduction): Likewise.
7819 Reword to avoid some formatting glitches.
7820 Use "#!/bin/sh", not "#! /bin/sh"; the space isn't needed these days.
7821 Clarify explanation of HP compiler bug.
7822 Redo example output tp match current CVS snapshot.
7823 Use @example.org in email addresses when the examples
7824 might get inadvertently cut-and-pasted into user code.
7825 Remove example of autom4te usage that doesn't seem to work now.
7826 Use modern AC_INIT (except when the example is meant to be
7827 shown with Autoconf 2.13).
7828 Update ksh info for Solaris 9 and later.
7830 Modernize description of Automake versions a bit.
7831 Don't claim a future version of Autoconf is near.

7837 follows its own advice about quoting better.
7838 Reword to avoid some formatting glitches.
7839 * doc/installt.exi: Reword to avoid some formatting glitches.
7841 * doc/autoconf.texi (Limitations of Builtins) <case>: Mention
7842 Tru64 ksh pattern matching bug. Reported against Libtool by
7843 Albert Chin <libtool@mlists.thewrittenword.com> and
7844 Nicolas Joly <njoly@pasteur.fr>.
7846 2005-06-06 Stepan Kasal <kasal@ucw.cz>
7848 m4_cdr of one-member list was [[]] (one-member list containing an
7849 empty string) instead of [] (an empty list. Callers were skewed to
7850 match this misbehaviour. As a consequence of this:
7851 - m4_foreach([x], [], [foo]) expanded to `foo', while
7852 - the expansion of m4_foreach([x], [[]], [foo]) was empty.
7853 This bug has been fixed:
7855 * lib/m4sugar/m4sugar.m4 (m4_cdr): If only one argument is given,
7856 expand to an empty string; print error msg if called without
7858 (m4_foreach, m4_map, m4_map_sep): Don't expect the previous
7859 misbehaviour; handle [] and [[]] correctly.

7865 scripts created and the loop applying them, use _AC_SED_CMD_LIMIT.
7867 2005-06-06 Ralf Menzel <menzel@ls6.cs.uni-dortmund.de> (trivial change)
7869 * doc/autoconf.texi (Limitations of Usual Tools): Solaris' awk cannot
7870 swallow records with more than 99 fields.
7871 * lib/autotest/general.m4 (AT_INIT): Use the awk builtin `split' to
7872 parse the long line.
7874 2005-06-04 Stepan Kasal <kasal@ucw.cz>
7876 * doc/autoconf.texi (Limitations of Usual Tools): AIX awk cannot
7877 swallow literals longer than 399. Reported by Ralf Wildenhues.
7878 * lib/autotest/general.m4 (AT_INIT): Pass $at_groups though stdin,
7879 to workaround this limitation.
7881 2005-06-03 Steven G. Johnson <stevenj@alum.mit.edu>
7883 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Find g95 in addition
7884 to gfortran, and make these the first two compiler names
7885 checked (following the general autoconf preference for gcc).

7889 * tests/Makefile.am (check_SCRIPTS): Set to $(wrappers).
7890 (DISTCLEANFILES): Remove $(check_SCRIPTS).

7895 * lib/autotest/general.m4 (AT_INIT): Don't create a regular
7896 expression of unbounded size when processing the --list
7897 option. This runs afoul of a limit of 399 bytes per regular
7898 expression on AIX. Problem reported by Ralf Wildenhues.
7900 2005-06-01 Paul Eggert <eggert@cs.ucla.edu>

7903 * doc/autoconf.texi (Particular Headers): Reword example
7904 for multiline stdbool replacement.
7905 (Setting Output Variables): Reword text a bit. Don't
7906 give all the details about |#_!!_#|.
7907 Reword description of line replacement.
7909 2005-05-31 Dan Manthey <dan_manthey@partech.com>
7911 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Output variables may
7912 now contain newlines, and substituted files must be referenced on
7913 a line alone; the sed scripts to substitute them are now very
7915 (_AC_SED_CMD_LIMIT): Added; single place to store limit on how many
7916 commands can be put in a sed script portably.
7917 * doc/autoconf.texi (Setting Output Variables): Document above
7918 changes. (Particular Header Checks) <AC_HEADER_STDBOOL>: Give exaple
7919 use of multiline substitution.

7929 * tests/local.at: Don't attempt to check for negated character
7930 classes in shell scripts. The test was too brittle.
7932 2005-05-25 Stepan Kasal <kasal@ucw.cz>
7934 * bin/autoconf.as: Don't use "shift 2"; it's not portable enough.
7935 * doc/autoconf.texi (Limitations of Builtins): Document this
7938 2005-05-24 Stepan Kasal <kasal@ucw.cz>
7940 * lib/m4sugar/m4sh.m4 (_AS_ECHO_LOG): New macro to factor out
7941 common code; used in many places in the tree.
7942 (AS_ESCAPE): Make the pattern a bit simpler; use \& insetad of \1.
7943 (_AS_ECHO_UNQUOTED): Move the macro lower; no code change.
7945 * lib/m4sugar/m4sugar.m4 (m4_ifset): Use m4_ifval.

7948 messages when ac_unique_file is not found.
7949 (AC_CONFIG_MACRO_DIR): Simplify the `if' at the end.
7950 (AC_MSG_CHECKING, AC_MSG_RESULT): Put braces around the two echo
7951 commands, for consistency with AC_MSG_ERROR and such.
7953 * bin/autoconf.as: Make more use of "shift 2" in option processing.

7966 * lib/autoconf/status.m4 (_AC_SRCDIRS): Rename ...
7967 (ac_top_builddir): ... this ...
7968 (ac_top_build_prefix): ... to this; the old name is also kept, for
7969 backward compatibility.
7970 (ac_top_builddir_sub): New variable, without the trailing slash,
7972 (_AC_OUTPUT_FILES): s/@top_builddir@/$ac_top_builddir_sub/
7973 * doc/autoconf.texi (Configuration Actions): Rename
7974 ac_top_builddir to ac_top_build_prefix.

7986 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Don't m4_quote the second
7987 argument to m4_foreach. I guess it was necessary in the past,
7988 but I think it's a no-op now.

7992 * lib/autoconf/general.m4 (_AC_INIT_HELP): Merge two consecutive
7993 ``cat <<_ACEOF'' commands to one.

7999 * lib/autotest/general.m4 (AT_INIT): Use expr to get the numbers from
8001 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Use awk to search for
8002 the wrong patterns between ``case'' and ``esac.'' The previous

8072 quoting rules. Problems noted by Stepan Kasal.
8073 Also, throughout this document, be more careful about white space.
8074 "blank", "white space", and "space" all have different meanings
8075 and we should be careful to say what we mean.

8114 * doc/autoconf.texi (External Software): Replace AC_DEFINE_UNQUOTED
8115 by AC_DEFINE; it was a mistake.
8116 From bug reported against libtool by Dalibor Topic <robilad@kaffe.org>.
8118 2005-04-25 Stepan Kasal <kasal@ucw.cz>
8120 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): A tiny optimization.
8122 2005-04-22 Stepan Kasal <kasal@ucw.cz>

8194 a directory whose name contains a special character like space,

8209 (_AC_INIT_SRCDIR): Use ac_pwd rather than invoking pwd.
8210 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Propagate
8211 ac_pwd, and quote srcdir.
8212 * lib/autotest/general.m4 (AT_INIT): Quote file name args.
8214 * doc/autoconf.texi: Fix some systematic formatting problems.
8215 ".)" needs a following @: if not at the end of a sentence, and
8216 similarly for "!)". "etc." should be preceded by a comma.
8217 "n-th" -> "@var{n}th". pdksh is still buggy, so update its date.
8219 2005-03-22 Bruno Haible <bruno@clisp.org>
8221 * doc/autoconf.texi (Input): Mention that AC_CONFIG_AUX_DIR's

8233 * lib/autoconf/c.m4 (AC_PROG_CC): Be more careful to skip
8234 `/usr/ucb/cc'; use `cl.exe' to distinguish the MS compiler
8235 from a Common Lisp's `cl'.
8236 (AC_PROG_CXX): Behave according to the documentation: don't
8237 search for $ac_tool_prefix$CCC and $CCC, just set CXX=$CCC;
8238 make the variable CCC precious; use `cl.exe', not `cl'.

8241 Alexandre Duret-Lutz <adl@gnu.org>
8243 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin from
8244 /dev/null, as "configure" shouldn't read stdin, and this insulates
8245 us from problems (e.g., when testing for "cl"). Also, do this
8246 redirection before invoking "hostname" or "uname", and keep the
8247 original input stream available via...
8248 (AS_ORIGINAL_STDIN_FD): ... this new macro.
8249 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't

8261 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N_PREPARE): Don't set ECHO_C to
8262 newline if neither \c nor -n work, as that would output two
8263 newlines. Prefer -n to \c. Reported by Stepan Kasal.

8267 * lib/m4sugar/m4sh.m4 (AS_IF): Define by m4_defun, not m4_define.
8268 This causes that any required macros inside will get before the if.

8271 2005-02-12 Paul Eggert <eggert@cs.ucla.edu>
8273 Undo previous change, except keep the change to
8274 lib/autoconf/programs.m4 that replaced grep with shell
8275 pattern-matching. This is because net-snmp configure reads stdin.
8276 Reported by Noah Misch.

8280 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin
8281 from /dev/null, as "configure" shouldn't read stdin, and this
8282 insulates us from problems (e.g., when testing for "cl").
8283 Suggested by Alexandre Duret-Lutz. Also, do this redirection
8284 before invoking "hostname" or "uname".
8285 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
8286 _AC_LINK_IFELSE): Undo previous change, as it's no longer needed.
8287 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Don't bother with
8288 "</dev/null" since it's now done at the top of 'configure'.
8289 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
8290 * lib/autoconf/programs.m4 (_AC_PATH_PROG_FLAVOR_GNU): Likewise.
8291 Also, replace grep with shell pattern-matching, to save a process.

8295 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
8296 _AC_LINK_IFELSE): Redirect stdin to /dev/null, in an attempt to
8297 avoid thinking that Allegro Common Lisp's "cl" command is a C++
8300 2005-02-09 Paul Eggert <eggert@cs.ucla.edu>

8311 2005-02-07 Paul Eggert <eggert@cs.ucla.edu>
8313 * doc/autoconf.texi: Use @acronym for DJGPP.
8314 Fix some @code's that should have been @env's, and vice versa.
8315 Sort environment variable names.
8316 Mention that shells no longer inherit IFS.
8317 Don't recommend PATH_SEPARATOR=';' so strongly.
8318 Mention that $RANDOM might expand to the empty string.
8319 "symlink" and "soft link" -> "symbolic link".
8320 Improve mktemp description (reported by Bruno Haible).

8396 this fixes a bug tickled by the AT_CAPTURE_FILE change noted below.

8459 Simplify the implementation of m4_require (a.k.a. AC_REQUIRE).
8460 Update the long comment explaining it.
8462 m4_require no longer writes an ``is required by'' line to the
8463 execution stack. It contains only one bit of non-redundant
8464 information: that the macro was required, not called. And even
8465 this bit is useless in most situations: have you ever met a macro
8466 which both calls and requires the same macro?
8468 * lib/m4sugar/m4sugar.m4 (_m4_defun_pro): Don't push a diversion...
8469 (_m4_defun_pro_outer): ... only via this macro, for the outermost

8472 (m4_expansion_stack_pop): Remove the misplaced comment.

8474 execution stack; slightly improve the out-of-a-defun error message.
8475 (_m4_divert_grow): New macro, counter for the temporary diversions.
8476 (_m4_require_call): Use it.
8477 * tests/m4sugar.at (m4_require): Expect output without the

8517 Warn about newline stripping in `` and $(). Update Solaris
8519 (Limitations of Builtins): Use expr "X...", not expr "x...", as
8520 X insulates us from future changes to Posix.

9039 * Makefile.cfg (wget_files): Remove config.guess, config.sub,
9040 texinfo.tex for now (done by hand now).
9041 * Makefile.maint (wget_files, cvs_files):
9042 Remove ansi2knr.c; nobody uses it.
9043 (ansi2knr.c-url_prefix): Remove.
9044 (cvs-update): Fix test for failure. I don't know why it ever
9047 * doc/autoconf.texi: Update URLs, some of which went stale.
9048 Use @uref rather than @href.
9050 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Have configure
9051 handle "--" as per POSIX. Suggested by Paul Pogonyshev.
9053 * config/config.guess, config/config.sub, config/elisp-comp,
9054 config/install-sh, config/mkinstalldirs, config/texinfo.tex,
9055 doc/fdl.texi, doc/standards.texi: Sync with master copy.
9057 * NEWS, TODO, configure.ac, bin/autoscan.in,
9058 bin/autoupdate.in, bin/ifnames.in, doc/autoconf.texi,
9059 doc/install.texi, lib/Autom4te/Configure_ac.pm,

9063 lib/m4sugar/m4sugar.m4, tests/local.at, tests/m4sh.at,
9064 tests/tools.at, tests/torture.at:
9065 Use "file name" rather than "filename" or "path",
9066 to be consistent with the terminology of the GNU coding standards.
9068 2004-08-19 Paul Eggert <eggert@cs.ucla.edu>
9070 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C),
9071 AC_C_LONG_DOUBLE): Undo 2004-06-04 change, as it didn't work with
9072 HP-UX 11.23 cc/aCC or Tru64 4.0 cc. Problem reported by Noah Misch in
9073 <http://lists.gnu.org/archive/html/autoconf/2004-07/msg00004.html>.
9075 More fixes to support spaces in the name of the build directory.
9076 This isn't a complete fix but it's an improvement.
9078 * bin/autoconf.as (autom4te_options): New var.
9079 Use it instead of appending to AUTOM4TE, so that we can allow
9080 spaces in the build directory's absolute name.
9081 * bin/autoheader.in ($autoconf): Allow spaces in file names.
9082 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP, _AT_CHECK,
9083 AT_CHECK_NOESCAPE): Likewise.
9084 * tests/wrapper.as (testdir, AUTOM4TE_CFG, autom4te_perllibdir,
9085 main program): Likewise.
9087 2004-08-18 Paul Eggert <eggert@cs.ucla.edu>
9089 * lib/autoconf/general.m4 (_AC_INIT_HELP): Quote $ac_popdir uses.
9090 From Ralf Corsepius in:
9091 http://lists.gnu.org/archive/html/autoconf-patches/2004-08/msg00014.html
9093 2004-08-12 Paul Eggert <eggert@cs.ucla.edu>
9095 * doc/autoconf.texi (Function Portability): Document isinf and
9096 and isnan. From a suggestion by Kevin Ryde.
9098 * lib/Autom4te/General.pm (END): Return correct exit status even
9099 if unlink succeeds and sets $?. Needed with Solaris 8's perl 5.00503.
9101 2004-08-09 Paul Eggert <eggert@cs.ucla.edu>
9103 * tests/torture.at (Deep Package): Use configure.in, not configure.ac,
9104 for compatibility with Automake 1.4. Reported by J C Fitzgerald in
9105 <http://lists.gnu.org/archive/html/bug-autoconf/2003-08/msg00051.html>.
9107 2004-08-04 Alexandre Duret-Lutz <adl@gnu.org>
9109 * lib/autoconf/general.m4 (AC_REQUIRE_AUX_FILE): New empty macro.
9110 (AC_CANONICAL_BUILD): Call it to require config.sub and config.guess.
9111 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Likewise for install-sh.
9112 * doc/autoconf.texi (Input): Document AC_REQUIRE_AUX_FILE.
9113 * lib/autom4te.in (Automake-preselections): Preselect
9114 AC_REQUIRE_AUX_FILE. Automake 1.10 will trace it.
9116 2004-08-02 Alexandre Duret-Lutz <adl@gnu.org>
9118 * lib/autom4te.in (Automake-preselections): Preselect
9119 AC_CANONICAL_BUILD and AC_CANONICAL_TARGET. Automake 1.9.1 will
9122 2004-07-29 Paul Eggert <eggert@cs.ucla.edu>
9124 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): Set BIN_SH, for
9126 * doc/autoconf.texi (Shellology): Mention BIN_SH.
9127 Document problem with "`""`" in pdksh POSIX mode.
9129 2004-07-27 Paul Eggert <eggert@cs.ucla.edu>
9131 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): Use "set -o posix"
9132 with pdksh, too. Problem reported by Patrick Welche via
9134 * doc/autoconf.texi (Shellology): Note that set -o posix is
9135 useful for pkdsh, too.
9137 2004-06-24 Paul Eggert <eggert@cs.ucla.edu>
9139 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Require
9140 _AS_UNSET_PREPARE, so that we can use $as_unset directly.
9141 Don't fail if ENV or BASH_ENV is readonly.
9142 (AS_SHELL_SANITIZE): Don't fail if ENV, MAIL, MAILPATH, LC_ALL,
9143 etc. are read only. Problem reported by Ludovic Courtes.
9145 2004-06-23 Noah Misch <noah@cs.caltech.edu>
9147 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): If the shell is
9148 zsh, disable GLOB_SUBST to avoid backslash handling problems.
9151 2004-06-04 Paul Eggert <eggert@cs.ucla.edu>
9153 * doc/autoconf.texi (File System Conventions): Warn about
9154 names like "aux". Problem reported by Eric Blake.
9156 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY (C)): Use division
9157 by zero instead of array size, so that we can use any arithmetic
9158 constant expression (instead of requiring an integer constant
9159 expression). This allows us to test expressions like DBL_MAX <
9160 LDBL_MAX, which didn't conform to the C standard using the old
9162 (AC_C_LONG_DOUBLE): Put back in the tests for LDBL_MAX and LDBL_EPSILON,
9163 now that we can do floating-point tests at compile time.
9165 2004-06-02 Paul Eggert <eggert@cs.ucla.edu>
9167 * lib/autoconf/c.m4 (AC_C_LONG_DOUBLE): Don't check LDBL_MAX
9168 and LDBL_EPSILON, as the resulting expression isn't an
9169 integer constant expression and violates the C standard.
9170 Problem reported by Nelson H. F. Beebe. Also, check
9171 for "L" suffix, and check that long double doesn't have
9172 worse range or precision than double, that mixed-mode
9173 arithmetic doesn't generate a diagnostic, that double
9174 constants fit in long double.
9176 2004-06-03 Kevin Ryde <user42@zip.com.au>
9178 * doc/autoconf.texi (Function Portability): Add notes on free(NULL),
9179 malloc(0) and realloc(NULL,size).
9181 * doc/autoconf.texi (Shell Substitutions): Spelling error reported by
9184 2004-05-31 Paul Eggert <eggert@cs.ucla.edu>
9186 * lib/autoconf/headers.m4 (HAVE_STDBOOL_H): Detect _Bool bug
9187 in HP aC++/ANSI C B3910B A.05.55 [Dec 04 2003]. Problem reported
9190 2004-05-26 Paul Eggert <eggert@cs.ucla.edu>
9192 * doc/autoconf.texi (Limitations of Builtins): Mention that ! COMMAND
9193 can be rewritten using if-then-else. Suggested by Bruno Haible.
9195 2004-05-25 Paul Eggert <eggert@cs.ucla.edu>
9197 * doc/autoconf.texi (testsuite Scripts): Fix typo.
9198 Problem reported by Stepan Kasal.
9200 2004-05-24 Paul Eggert <eggert@cs.ucla.edu>
9202 * tests/Makefile.am (autoconfdir): Fix to match comment (trivial
9203 change). Patch reported by Ralf Wildenhues in
9204 <http://mail.gnu.org/archive/html/bug-autoconf/2004-05/msg00092.html>.
9206 * lib/autoconf/functions.m4 (AC_FUNC_MBRTOWC): Don't assume that a
9207 function F exists if the compiler and linker let you compile an
9208 expression like (F != 0). Recent versions of GCC optimize away
9209 the reference to F in that case, since every function address must
9210 be nonzero, so the link succeeds even if F does not exist.
9211 Problem reported by Manu in
9212 <http://mail.gnu.org/archive/html/bug-gnu-utils/2004-05/msg00060.html>.
9214 * doc/autoconf.texi (Systemology): Standardize on the spelling of
9215 "Unix". Many uses changed.
9216 (Limitations of Builtins): Explain better why the ! command isn't
9219 2004-05-22 Alexandre Duret-Lutz <adl@gnu.org>
9221 * lib/autom4te.in (Automake-preselections): Preselect
9222 LT_SUPPORTED_TAG in lieu of AC_LIBTOOL_TAGS.
9224 2004-05-19 Kevin Ryde <user42@zip.com.au>
9226 * doc/autoconf.texi (Function Portability): Add strerror_r, cross
9227 referencing AC_FUNC_STRERROR_R.
9229 * doc/autoconf.texi (Particular Functions): In AC_FUNC_CLOSEDIR_VOID,
9230 note pessimistic assumption when cross compiling.
9232 2004-05-16 Paul Eggert <eggert@cs.ucla.edu>
9234 * doc/autoconf.texi (Limitations of Make): Note that BSD make
9235 (until 2004) invoked subcommands with sh -e, contra POSIX.
9236 Reported by Kevin Ryde.
9238 2004-05-10 Eric Sunshine <sunshine@sunshineco.com>
9240 * programs.m4 (_AC_PROG_GREP): Fixed bug where PATH argument handed to
9241 _AC_PATH_PROG_FEATURE_CHECK contained leading whitespace (i.e.
9242 " $PATH:/usr/xpg4/bin"). This resulted in bogus tests, such as
9243 `test -f " /usr/bin/grep"', which _always_ failed.
9244 (AC_PROG_SED): Ditto bogus PATH fix.
9245 * autoconf.texi (AC_PROG_GREP): Properly document that this macro
9246 requires that grep correctly supports _multiple_ `-e' options, rather
9247 than stating only that grep should accept `-e'.
9249 2004-05-03 Paul Eggert <eggert@cs.ucla.edu>
9251 Port to C99, which requires that 'exit' be declared.
9253 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Use AC_INCLUDES_DEFAULT
9254 to ensure that stdlib.h is included.
9255 * lib/autoconf/functions.m4 (_AC_LIBOBJ_ALLOCA, AC_FUNC_SETPGRP,
9256 AC_FUNC_STRTOD, AC_FUNC_SETVBUF_REVERSED, AC_FUNC_FORK, _AC_FUNC_FORK,
9257 _AC_FUNC_VFORK, AC_FUNC_WAIT3): Likewise.
9258 * lib/autoconf/specific.m4 (AC_SYS_RESTARTABLE_SYSCALLS): Likewise.
9259 * lib/autoconf/types.m4 (AC_TYPE_GETGROUPS): Likewise.
9260 * lib/autoconf/headers.m4 (AC_HEADER_STDC): Include <stdlib.h>
9261 when using 'exit' in a test; C99 requires that 'exit' be declared.
9263 2004-05-02 Paul Eggert <eggert@cs.ucla.edu>
9265 * doc/autoconf.texi (Particular Programs): AC_PROG_GREP
9266 now prefers 'grep' implementations that accept -e.
9267 (Limitations of Usual Tools): Describe problems of traditional
9268 egrep and fgrep with long input lines, and of traditional grep
9270 * lib/autoconf/programs.m4 (AC_PROG_GREP): Check for -e, too.
9271 (_AC_PROG_GREP): Assume 3rd arg is properly quoted for the shell.
9272 All callers changed. Append /usr/xpg4/bin to the PATH, for
9274 (_AC_FEATURE_CHECK_LENGTH): Discard stderr, so we don't bother
9275 the user with complaints about multiple -e options.
9276 * tests/local.at (AC_STATE_SAVE): Use $GREP, not grep.
9277 Define it with AC_PROG_GREP.
9278 * configure.ac (AC_PROG_GREP): Add.
9279 * lib/freeze.mk (GREP): New macro.
9281 2004-05-02 Eric Sunshine <sunshine@sunshineco.com>
9283 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Consult $SHELL as
9284 a possible candidate only after all others fail, rather than
9285 consulting it first. This improves backward compatibility by
9286 better reflecting the way shell selection occurred in previous
9287 versions of Autoconf, and should help to avoid triggering latent
9288 problems in other packages, such as the one in Automake where zsh
9289 is not handled robustly:
9290 http://mail.gnu.org/archive/html/automake/2004-04/msg00095.html
9291 Although it is not Autoconf's responsibility to work around
9292 problems in Automake, it nevertheless makes sense to avoid
9293 introducing unnecessary incompatibilites.
9295 2004-04-22 Albert Chin-A-Young <china@thewrittenword.com>,
9296 Gary V. Vaughan <gary@gnu.org>
9298 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Don't guess
9299 how deeply nested we are when a suitable tool is found, set the
9300 ac_path_TOOL_found flag.
9301 (_AC_PATH_PROG_FEATURE_CHECK): Encapsulate knowledge of how deeply
9302 nested we are in this macro. Break out of all 3 nested loops if
9303 ac_path_TOOL_found is set.
9305 2004-04-21 Gary V. Vaughan <gary@gnu.org>
9307 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Break out
9308 of the _AS_PATH_WALK loop too if GNU flavor is found.
9310 2004-04-21 Alexandre Duret-Lutz <adl@gnu.org>
9312 * doc/autoconf.texi (Limitations of Make): Update documentation
9313 for `$<'. New entry `Long lines', based on a report from Simon
9314 Josefsson. Augment the documentation for SHELL = @SHELL@ with a
9315 paragraph about DJGPP, based on a mail from Richard Dawe.
9317 2004-04-20 Paul Eggert <eggert@twinsun.com>
9319 * tests/c.at (C keywords): Don't assume that GCC supports
9320 "restrict" and "inline", as sufficiently-old GCC versions do not
9321 (also, GCC configured to be in pedantic C89 mode does not).
9322 Problem reported by Sumit Pandya in:
9323 http://mail.gnu.org/archive/html/autoconf/2004-04/msg00092.html
9325 * lib/autoconf/c.m4 (_AC_PROG_CC_G, _AC_PROG_CXX_G): Don't
9326 consider -g to work if it generates warnings when plain compiles
9327 don't. Problem reported by Braden McDaniel in:
9328 http://mail.gnu.org/archive/html/autoconf-patches/2003-07/msg00014.html
9330 * doc/autoconf.texi (Slashes): New section, to document a problem
9331 reported by Jim Meyering in:
9332 http://mail.gnu.org/archive/html/bug-coreutils/2004-02/msg00060.html
9334 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Remove potential
9335 linker output files before linking, to work around IRIX 6 linker bug.
9336 Problem reported by Rainer Orth in:
9337 http://mail.gnu.org/archive/html/autoconf-patches/2004-02/msg00007.html
9339 2004-04-20 Gary V. Vaughan <gary@gnu.org>
9341 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Make the
9342 best tool so far counter rely on the tool path variable name to
9343 avoid checks for one tool being affected by the results of running
9344 the length check on a previous tool.
9346 * lib/autoconf/programs.m4 (_AC_PROG_GREP): Take an additional
9347 match expression argument, as different greps have different
9348 regular expression flavours.
9349 (AC_PROG_FGREP): Pass 'FGREP'. fgrep treats all match chars as
9351 (AC_PROG_EGREP): Pass 'EGREP$'.
9352 (AC_PROG_GREP): Pass 'GREP$'.
9354 2004-04-20 Albert Chin-A-Young <china@thewrittenword.com>
9356 * lib/autoconf/programs.m4 (AC_PROG_GREP): Cache variable
9357 is `ac_cv_path_GREP', not `oc_cv_path_GREP'.
9359 2004-03-29 Paul Eggert <eggert@twinsun.com>
9361 * doc/autoconf.texi (Particular Headers, Particular Types, Generic
9362 Types, Specific Compiler Characteristics, System Services,
9363 Obsolete Macros): Use 'long int', 'short int', 'unsigned int'
9364 etc. consistently instead of 'long', 'short', 'unsigned' etc.
9365 * lib/autoconf/c.m4 (AC_LANG_INT_SAVE(C), AC_C_BIGENDIAN): Likewise.
9366 * lib/autoconf/functions.m4 (AC_FUNC_MMAP, AC_FUNC_SELECT_ARGTYPES):
9368 * lib/autoconf/headers.m4 (AC_HEADER_SYS_WAIT): Likewise.
9369 * lib/autoconf/types.m4 (AC_TYPE_GETGROUPS, AC_TYPE_SIZE_T,
9370 AC_TYPE_OFF_T): Likewise.
9371 * tests/semantics.at (AC_CHECK_TYPES: backward compatibility):
9374 * tests/foreign.at (Libtool): Create an empty aclocal.m4, to
9375 pacify libtool 1.5.2. Fix quoting problems in sed command.
9377 2004-03-28 Paul Eggert <eggert@twinsun.com>
9379 * doc/autoconf.texi (Particular Structures): AC_STRUCT_TIMEZONE
9380 now defines HAVE_DECL_TZNAME if it is declared, when
9381 HAVE_STRUCT_TM_TM_ZONE is not defined.
9382 * lib/autoconf/types.m4 (AC_STRUCT_TIMEZONE): Implement this.
9383 Do not assume atoi. Rely on HAVE_DECL_TZNAME when testing
9386 2004-03-28 Steven G. Johnson <stevenj@fftw.org>
9388 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Corrected
9389 superfluous backslashing of quotes (") in sed expressions;
9390 thanks to Paul Eggert.
9392 2004-03-26 Steven G. Johnson <stevenj@alum.mit.edu>
9394 * lib/autoconf/fortran.m4 (_AC_PROG_FC): new name of Intel
9395 Fortran compiler is ifort, also added pghpf; thanks to Nelson
9396 H. F. Beebe for the bug report.
9398 2004-03-26 Steven G. Johnson <stevenj@fftw.org>
9400 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): fix for
9401 quoted -cmdline argument in Portland Group compiler (bug
9402 reported by Jeffrey J. Barteet).
9404 2004-03-25 Kevin Ryde <user42@zip.com.au>
9406 * doc/autoconf.texi (Specifying Names): Move cross_compiling ovindex to
9407 (Run Time): ... here, where it's now mentioned.
9409 2004-03-19 Alexandre Duret-Lutz <adl@gnu.org>
9411 * doc/autoconf.texi (autom4te Invocation): Language Autoconf
9412 inherits from language Autoconf-without-aclocal-m4.
9413 (Customizing autom4te): Adjust example; the cache must now be
9414 disabled for language Autoconf-without-aclocal-m4.
9416 2004-03-16 Paolo Bonzini <bonzini@gnu.org>
9417 Nathanael Nerode <neroden@twcny.rr.com>

9426 AC_CHECK_TARGET_TOOLS, and warn for future changes
9427 in the behavior of AC_PATH_TOOL, AC_CHECK_TOOL and

9431 * tests/mktests.sh: Do not generate tests for the
9433 * NEWS: Document these changes.
9435 * doc/autoconf.texi: Avoid macros with unbraced arguments,
9436 they make TeX hang up.

9440 * NEWS: New macro AC_CHECK_ALIGNOF.
9441 * doc/autoconf.texi (Generic Compiler Characteristics): Document it.
9442 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Use long int rather than
9443 int; avoid "a `$1'" since this isn't grammatical if $1 begins with a
9445 (AC_CHECK_ALIGNOF): New macro.
9446 * tests/mktests.sh (ac_exclude_list): Exclude AC_CHECK_ALIGNOF.
9447 * tests/semantics.at (AC_CHECK_ALIGNOF): Add tests similar to
9450 2004-03-03 Paul Eggert <eggert@twinsun.com>
9452 * bin/Makefile.am (edit): Don't use $< in a context where
9453 POSIX doesn't require support for it. Use $@.in instead.
9454 Problem reported by Anthony N. Frasso in
9455 <http://mail.gnu.org/archive/html/autoconf/2004-03/msg00008.html>.
9456 * bin/autoscan.in, bin/autoupdate.in: Add @configure_input@ comment.
9458 2004-02-23 Gary V. Vaughan <gary@gnu.org>
9460 * bin/autoreconf.in (autoreconf_current_directory): Recognize LT_INIT
9461 from the next generation of Libtool.
9462 * lib/autom4te.in (Autoreconf-preselections): Ditto.
9464 2004-02-20 Alexandre Duret-Lutz <adl@gnu.org>
9466 * doc/autoconf.texi (Limitations of Usual Tools) <mkdir>: `mkdir -p'
9467 is not always thread-safe. Report from Nathanael Nerode.
9469 2004-02-18 Paul Eggert <eggert@twinsun.com>
9471 Fix a dependencies problem, stemming from a Autoconf 2.59 build
9472 problem on QNX reported by Stephen Rasku in
9473 <http://mail.gnu.org/archive/html/bug-autoconf/2004-02/msg00066.html>.
9475 * bin/Makefile.am ($(srcdir)/autoconf.in): Depend on
9476 $(m4sh_m4f_dependencies); this removes a FIXME.

9481 2004-02-09 Paul Eggert <eggert@twinsun.com>
9483 * doc/autoconf.texi (Setting Output Variables): Emphasize that
9484 AC_SUBST provides no portable way to escape literal newlines.
9486 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS): Ignore all
9487 flags of the form -lcrt*.o, not just -lcrt[01].o and -lcrtbegin.o.
9488 Darwin uses -lcrt2.o and there's little point to cataloging all
9489 the system variants. Partial fix reported by Andreas Waechter in:

9508 correctly the behavior of the third argument. Document
9509 what the three macros that AU_DEFUN defines do. Fix
9510 warning message when the third argument includes $0
9511 (reported by Alexandre Duret-Lutz).

9514 Eric Sunshine <sunshine@sunshineco.com>
9515 Paul Eggert <eggert@twinsun.com>
9517 * lib/m4sugar/m4sh.m4 (M4SH-SANITIZE): New diversion.

9534 use AS_INIT_WITH_SHELL_FN.
9535 * bin/autoconf.in, tests/wrapper.in: Regenerated.
9537 2004-01-30 Paolo Bonzini <bonzini@gnu.org>

9565 * lib/autoconf/general.m4 (_AC_INIT_COPYRIGHT): Add 1992 thorugh
9566 2003 (except 1997) to the list of copyright years. This undoes
9567 the 2003-05-22 change, which removed the older years from the list.
9568 * lib/autoconf/status.m4 (AC_OUTPUT): Update copyright date to 2004.

9579 egrep and fgrep respectively if $GREP -E/-F don't work.
9580 (_AC_PATH_PROG_FEATURE_CHECK): Factor out the common core of
9581 _AC_PROG_GREP, and AC_PROG_SED.
9582 (_AC_FEATURE_CHECK_LENGTH): New helper macro for finding the

9614 * doc/autoconf.texi (Default Includes): Include <stdint.h> even if
9615 HAVE_INTTYPES_H is defined. This is needed on Tru64 5.1b with
9616 Compac C V6.5-207 (dtk), which defines uintmax_t in <stdint.h> but
9617 not <inttypes.h>. Problem reported by Tim Mooney in
9618 <http://mail.gnu.org/archive/html/bug-coreutils/2004-01/msg00147.html>.
9619 * lib/autoconf/headers.m4 (_AC_INCLUDES_DEFAULT_REQUIREMENTS):
9622 * lib/autoconf/programs.m4 (AC_PROG_SED): Use diff, not sed;
9623 otherwise "make check" fails because it forbids cmp (I guess
9624 because cmp treats files as binary on DOS-like systems).
9626 * tests/mktests.sh: Update copyright date to 2004, since some tests
9627 have changed in 2004.
9629 2004-01-23 Gary V. Vaughan <gary@gnu.org>

9632 non-truncating sed or gsed program in PATH.

9637 2004-01-15 Paul Eggert <eggert@twinsun.com>
9639 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Try -std, not -std1, since
9640 -std1 disables some useful extensions on Tru64. Problem reported
9642 <http://mail.gnu.org/archive/html/autoconf/2004-01/msg00100.html>.
9644 2004-01-14 Paul Eggert <eggert@twinsun.com>
9646 * doc/autoconf.texi (Programming in M4sh): Document that
9647 AS_MKDIR_P succeeds if the destination is a symbolic link
9648 to an existing directory.
9649 (Limitations of Usual Tools): Note that mkdir -p might not
9650 succeed on symlinks to directories.
9652 2004-01-13 Paul Hilfinger <hilfinger@CS.Berkeley.EDU>
9654 * lib/autoconf/autoupdate.m4 (AU_DEFUN): Grammar fix in comment.

9664 2004-01-10 Jim Meyering <jim@meyering.net>
9666 * doc/autoconf.texi (Running the Preprocessor): Correct grammar.
9668 2004-01-09 Paul Eggert <eggert@twinsun.com>
9670 * lib/autoconf/general.m4: Fix bug: AC_CHECK_SIZEOF evokes a warning
9671 with `autoconf -Wall,error'. Bug reported by Eric Blake in:
9672 http://mail.gnu.org/archive/html/autoconf-patches/2004-01/msg00000.html
9673 (_AC_COMPUTE_INT_COMPILE): Invoke _AC_COMPILE_IFELSE, not
9674 AC_COMPILE_IFELSE, since we now assume our caller invokes
9675 AC_LANG_COMPILER_REQUIRE, for symmetry with _AC_COMPUTE_INT_RUN.
9676 (_AC_COMPUTE_INT_RUN): Likewise, for _AC_RUN_IFELSE instead
9677 of AC_RUN_IFELSE; this avoids the warning mentioned above.
9678 (_AC_COMPUTE_INT): Invoke AC_LANG_COMPILER_REQUIRE.
9680 2004-01-07 Paul Eggert <eggert@twinsun.com>
9682 * lib/autoconf/general.m4 (_AC_LIBOBJS_NORMALIZE): Avoid \$ inside
9683 `"'...'"`, as it's confusing (and I suspect it may not work on
9684 some platforms). The code was incorrect anyway, as it assumed
9685 that \$ evaluated to itself in that context. Reported by
9686 Alexandre Duret-Lutz.
9688 2004-01-07 Alexandre Duret-Lutz <adl@gnu.org>
9690 * lib/autom4te.in (Automake-preselections): Preselect AC_LIBTOOL_TAGS

9719 Use "rm -f" to remove conftest.sed, not plain "rm".
9720 Bug reported by David Relson in
9721 <http://mail.gnu.org/archive/html/autoconf/2004-01/msg00011.html>.
9723 * Makefile.am (autom4te-update):
9724 Replace "rm -rf" and "rm -fr" with "rm -f -r", as POSIX requires.

9740 * doc/autoconf.texi (Limitations of Usual Tools): Mention that cc
9741 -c -o might not work. From a suggestion by Kevin Ryde.
9742 (C Compiler, Generating Sources, Limitations
9743 of Usual Tools, Limitations of Make, Making testsuite Scripts):
9744 Don't put '-o' after non-options, as POSIX doesn't allow this.
9745 Mention that cc's name might be gcc or c89 or whatever.
9747 2004-01-04 Kevin Ryde <user42@zip.com.au>

9753 * bin/autoreconf.in (autoreconf_current_directory):
9754 Fix typo: mkdir without umask arg.
9756 2003-12-27 Alexandre Duret-Lutz <adl@gnu.org>
9758 * doc/autoconf.texi (Limitations of Make) <Automatic rule rewriting>:
9759 Documents OSF1/Tru64 make behavior. Replace `VPATH = ../src' by
9760 `VPATH = ../pkg/src' in examples to make the OSF1/Tru64 make
9761 explanation clearer.

9771 * configure: Regenerate.
9772 * tests/atlocal.in: Store the result here.
9773 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Extracted from

9775 of explicitly testing.

10046 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Omit quoted

10071 * lib/autoconf/fortran.m4 (_AC_PROG_FC_G): Use language-specific
10072 cache variable instead of $G77 to decide whether to include -O2,
10073 since $G77 is specific to Fortran 77.

10083 arguments so that it can be used with syntax identical to
10084 AC_PROG_F77, and so that we can more easily decide to
10085 remove/deprecate the DIALECT optional argument in the future if it
10086 proves troublesome.
10087 (AC_FC_FREEFORM): Exit 77 upon failure to fix test suite for
10088 non-freeform-supporting compilers. Document freeform flags.

10159 * lib/autoconf/status.m4 (_AC_OUTPUT_COMMANDS): Make sure the
10160 directory for AC_CONFIG_COMMANDS' first argument exists.
10161 This makes valid the invocation of _AC_SRCPATH that follows.

10186 The test suite are sometimes assigning timings incorrectly.
10187 Reported by Henk Krus.
10188 Diagnosed by Nicolas Joly.
10190 * lib/autotest/general.m4 (AT_CLEANUP): Rename AT_help as
10192 Instead of making AT_help a sequence of assignments to grow
10193 $at_help_all, just make AT_help_all be the growing contents of
10194 $at_help_all, and make a single assignment in...
10196 (at_times_skip): Flip the meaning and rename as...

10208 (ifnames): chmod -w.
10209 * tests/wrapper.as (AUTOCONF, AUTOM4TE, ): Point to tests/
10210 executables, not bin/ executables! Otherwise all the magic needed
10211 to find non installed files is turned off. This caused a failure
10212 of test 40 and 41 that ran aclocal 1.8 which in turn ran autom4te
10213 as found in its environment (sent by tests/autoreconf): pointing
10214 to bin/autom4te that could not find its files.
10215 * tests/mktests.sh: Force the replacement of generated files, for
10216 the sake of "mv" program that are interactive when overwriting a

10268 * tests/fortran.at (GNU Fortran 77): Also exercise AC_FC_SRCEXT
10269 and AC_FC_FREEFORM.

10313 Add support for newer Fortran dialects. The F77 interface is
10314 unchanged, and continues to support Fortran 77. New FC macros
10315 correspond to all the old F77 macros, with output variables FC,
10316 FCFLAGS, and FCLIBS. AC_PROG_FC defaults to picking the newest
10317 available dialect, but older dialects can be specified. There are
10318 new macros AC_FC_SRCEXT to set the source extension, and
10319 AC_FC_FREEFORM to accept free-form source files.
10321 * lib/autoconf/c.m4 (_AC_LANG_PREFIX(C), _AC_LANG_PREFIX(C++)):

10434 * bin/autoupdate.in: Adjust.
10435 Use &verb, not &verbose.
10437 2003-08-21 Akim Demaille <akim@epita.fr>
10439 * bin/autoheader.in (&parse_args): Use &parse_warnings and
10441 ($help): Use Autom4te::ChannelDefs::usage.
10442 * bin/autoscan.in: Use Autom4te::ChannelDefs.
10443 * lib/Autom4te/General.pm: Don't export error: you don't own it.
10445 2003-08-21 Akim Demaille <akim@epita.fr>
10447 First stab at preserving warnings between calls to autom4te,
10448 including when the cache is used.
10450 There are still several issues: (i) there are too many runs of m4
10451 (one for include, one for warnings, and some more), (ii) warnings
10452 spreading on several lines are not handled gracefully, (iii) the
10453 code meant to have the call stack display for errors does not work
10454 (its handling should move from m4 to autom4te).
10456 * bin/autom4te.in Autom4te::Channels, Autom4te::ChannelDefs):
10458 (@preselect): Add m4_warn.
10459 ($exit_status): Remove, use $exit_code.
10460 ($help): Use Autom4te::ChannelDefs::usage.
10461 (&handle_m4): No longer define the m4_warnings.
10462 At each run, extract and report the warnings.
10463 Always cache the result, including if the exit status is on
10464 failure, since if nothing changes, we should result in the same
10465 failure, hence we can use the cache.
10466 * lib/m4sugar/m4sugar.m4 (m4_warning_ifelse, _m4_warning_ifelse)
10467 (_m4_warning_error_ifelse, __m4_warning_error_ifelse, _m4_warn):
10469 (m4_warn): Redefine as a do-nothing: it is its invocation that
10470 matters, as warnings are now reported via traces.
10471 * lib/autoconf/general.m4 (AC_DIAGNOSE): Don't make it a copy of
10472 the contents of m4_warn: make it _call_ m4_warn, so that tracing
10473 the latter reveals calls to the former.
10477 * tests/m4sugar.at (m4@&t@_warn): Use existing warning categories.
10479 2003-08-21 Akim Demaille <akim@epita.fr>
10481 * bin/autoreconf.pm (Autom4te::Channels, Autom4te::ChannelDefs):

10486 * lib/Autom4te/FileUtils.pm (&find_file): Walk the @include in
10488 * lib/Autom4te/ChannelDefs.pm: Doc typos.
10489 (&parse_warnings): Accept a list of warning requests.
10490 (&usage): Return a string, not a side effect.
10491 (cross): New warning category.

10495 * lib/Autom4te/Configure_ac.pm (&find_configure_ac)
10496 (&require_configure_ac): Accept an optional directory argument.
10497 ($configure_ac): Remove.
10498 * lib/Autom4te/General.pm (&find_configure_ac, &canonfile)
10499 (&catfile): Remove.
10500 * bin/autoheader.in, bin/autoreconf.in, bin/autoupdate.in,

10510 * bin/autoupdate.in, bin/autoheader.in, bin/autoreconf.in,
10511 * bin/autom4te: Adjust.
10512 In particular, be Autoconf tools are really silent when properly
10513 working, bind the verbosity of the 'note' channel to $verbose.
10514 * lib/Autom4te/General.pm (&find_file, &mtime, &update_file)
10515 (&xsystem, &contents): Remove, since they are exported by...
10516 * lib/Autom4te/FileUtils.pm: this.
10518 * lib/Autom4te/General.pm (&up_to_date_p): Move to...
10519 * lib/Autom4te/FileUtils.pm: here.

10634 From Gareth McCaughan.
10636 2003-06-23 Akim Demaille <akim@epita.fr>
10638 * lib/autotest/general.m4 (AT_INIT): Report a single config.log,
10639 not all of them. This fixes 1. the fact that when testing
10640 Autoconf there are many many config.log, 2. the incorrect use of
10641 top_srcdir to find config.log.
10642 Don't mix the detailed output of failed test with the summary of
10643 failures. Rather, append detailed log afterwards.
10645 2003-06-23 Akim Demaille <akim@epita.fr>
10647 * tests/local.at (AT_CHECK_CONFIGURE): Adjust to the verbose being
10648 always run: output config.log on $at_group_log.

10736 63 for version mismatches.

10760 Paul Eggert <eggert@twinsun.com>
10762 * lib/autoconf/c.m4 (_AC_PROG_CXX_EXIT_DECLARATION):
10763 Remove `#include <stdlib.h>' from the list; we should never
10764 make confdefs.h include <stdlib.h> or <cstdlib>, because the
10765 resulting namespace pollution would cause other tests to fail.
10766 Configure scripts run with some older versions of g++ and HP's
10767 aCC would fail due to such an #include. Problems reported by
10768 Matthew Mueller in <http://bugs.debian.org/120704> and by
10770 <http://mail.gnu.org/archive/html/autoconf/2003-05/msg00063.html>.
10771 In the test, use the test declaration before including <stdlib.h>,
10772 as that's closer to how it'll be used.

10776 * doc/autoconf.texi (Header Portability): ucred.h.
10779 2003-05-22 Paolo Bonzini <bonzini@gnu.org>
10781 Overhaul Autotest's logging: generate separate log files
10782 in testsuite.dir/NNN/testsuite.log, and append them to
10783 testsuite.log instead of re-running the test verbosely.
10785 * lib/autotest/general.m4 (AT_INIT): Use a single redirected
10786 file descriptor, write 0 to at_status_file instead of setting
10787 at_status=0, initialize some new variables (at_status_file,
10788 at_group_log, at_suite_log, at_tee_pipe). Remove the cruft
10789 to rerun the tests, instead append the at_group_log to the
10790 at_suite_log when a test fails.
10791 (AT_SETUP): pipe the test case's output into at_tee_pipe,
10792 with the AS_MESSAGE_LOG_FD redirected to stdout.
10793 (AT_CLEANUP): save the output status in $at_status_file
10794 and restore it, redirect the AS_MESSAGE_LOG_FD back to
10795 its original place.
10796 (AT_CHECK): since tests are run with a redirected stdout,
10797 and used to be re-run in verbose mode, turn some $at_verbose
10798 into echo, and don't redirect the output of testing stdout
10801 * lib/autotest/autoconf.texi (testsuite Scripts): Update

10919 * lib/Autom4te/XFile.pm (lock, truncate): Do not pass @_ to flock
10922 2003-05-06 Akim Demaille <akim@epita.fr>
10924 Don't try to be smart with aclocal 1.8+ because (i) aclocal no
10925 longer updates aclocal.m4 if useless, (ii) if a file m4_included
10926 by aclocal.m4 is changed it might require the importing of another
10927 m4 extension file, i.e., aclocal must be run.
10929 * bin/autoreconf.in (&run_aclocal, $aclocal_supports_force): New.
10930 (&parse_args): Use --force with aclocal if required and supported.
10931 (&autoreconf_current_directory): Use &run_aclocal.
10933 2003-05-06 Akim Demaille <akim@epita.fr>
10935 Lock autom4te's cache.
10937 * lib/Autom4te/XFile.pm ($me, &name, &lock, &truncate, &seek): New.
10938 * bin/autom4te.in (&Request::save, &Request::load): Use an IO::File
10939 argument instead of a file name, so that the request file remains
10940 open during the whole autom4te run.
10941 ($icache_file): New.
10942 (&freeze): Lock the $icache_file.
10944 2003-04-29 Derek Price <derek@ximbiot.com>
10946 * lib/autotest/general.m4 (AT_KEYWORDS): Don't use a comma as the
10947 seperator with m4_append_uniq(). It doesn't work.
10948 (AT_CLEANUP): Add `;' to end of at_help_all.
10949 (AT_INIT): Allow --keywords to be specified more than once. When
10950 grepping $at_help_all for keywords, use the field and keyword
10951 seperators to ensure a complete keyword match. Alter at_prev handling
10952 to support the new --keywords behavior.
10954 2003-04-27 Karl Berry <karl@freefriends.org>
10956 * doc/autoconf.texi: Make the dir entries in the autoconf manual
10957 align better with others. I also made some of the individual
10958 entries on one line, for brevity and to make it easier for me to
10959 sort my dir-example file in the Texinfo distribution :).

11026 header causes problems.
11028 2003-03-28 Akim Demaille <akim@epita.fr>
11030 * tests/torture.at (Configuring subdirectories): Require aclocal
11031 1.4, otherwise the test fails, as it does support configure.ac.
11032 This fixes the "test 40 failed" bug reports.
11034 2003-03-28 Akim Demaille <akim@epita.fr>
11036 * doc/autoconf.texi (C Compiler): `#line' portability.

11054 * lib/autoconf/general.m4 (AC_ARG_VAR): Use AS_HELP_STRING instead of
11055 obsolete AC_HELP_STRING.
11056 (AC_HELP_STRING): AU_DEFUN to...
11057 * lib/m4sugar/m4sh.m4 (AS_HELP_STRING): ...here.
11058 * tests/m4sh.at (AS_HELP_STRING): New test.

11062 2003-03-26 Derek Price <derek@ximbiot.com>
11064 * lib/autotest/general.m4: s/DEFAULT/DEFAULTS/ since it makes more
11065 sense. Verbosify the diversion definitions comment.

11103 an old Automake change. Discuss NetBSD, FreeBSD, OpenBSD, and
11104 Tru64 make in the "target lookup" section.
11105 (Automake): Automake 1.5+ no longer requires special tools to be
11106 present on the developer's host.
11108 2003-02-26 Richard Dawe <rich@phekda.freeserve.co.uk>
11110 * bin/autoheader.in (BEGIN): For DJGPP SHELL may not be set
11111 to a shell that can handle redirection or quoting correctly.

11117 * bin/autoupdate.in (BEGIN): Likewise.
11118 * bin/ifnames.in (BEGIN): Likewise.
11120 * bin/ifnames.in: Add final newline to help and version messages.
11122 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Translate colons,
11123 to cope with DOS-style absolute paths, when constructing
11126 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS, _AC_OUTPUT_FILES):
11127 When constructing paths with IFS=:, quote the path. If we're
11128 constructing a DOS-style absolute path, we don't want to split it
11131 * tests/atspecific.m4 (AT_CHECK_CONFIGURE): Fix typo
11134 2003-02-25 Pavel Roskin <proski@gnu.org>

11142 2002-09-01 patch by replacing "test -n" with "test -z".
11143 This fixes a bug found by Jeff Painter and reported by Tom Epperly in
11144 <http://mail.gnu.org/archive/html/autoconf/2003-02/msg00139.html>.
11146 * doc/autoconf.texi (Shell Substitutions): test -n -> test -z,
11147 to fix a mismatch between example and discussion.

11151 * doc/autoconf.texi (Limitations of Builtins): Add notes on printf
11152 format starting with "-".
11154 2003-02-20 Alexandre Duret-Lutz <adl@gnu.org>
11156 * doc/autoconf.texi (Limitations of Make): `foo=bar make -e'
11157 is not portable inside Makefile.
11159 2003-02-20 Akim Demaille <akim@epita.fr>
11161 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): When
11162 compiler says yeah, but preproc says nope, compiler is right.
11163 Conversely, prompt the reader to send a bug report to the
11164 maintainers of the package, not of Autoconf.
11166 2003-02-20 Klee Dienes <kdienes@apple.com>
11168 * bin/autoreconf.in (autoreconf_current_directory): Properly
11169 handle an empty aclocal.m4.

11174 $ac_prefix_program.
11177 2002-12-23 Paul Eggert <eggert@twinsun.com>
11179 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Define $1 to an
11180 innocuous variant befor including <limits.h> or <assert.h>. This
11181 works around a bug reported by Albert Chin: HP-UX 11i
11182 (and earlier versions) have a <limits.h> that declares
11183 gettimeofday and many other functions.
11185 2002-12-03 Paul Eggert <eggert@twinsun.com>
11189 * NEWS, configure.ac: Update version.
11191 * doc/fdl.texi: Upgrade to FDL version 1.2.
11193 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Use the function f
11194 nontrivially in main's body, so that f's external declaration is
11195 not optimized away in AIX. This should fix the bug reported by
11197 <http://mail.gnu.org/pipermail/autoconf/2002-November/014508.html>.
11199 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C),
11200 _AC_PROG_PREPROC_WORKS_IFELSE): Use <limits.h> if __STDC__ is
11201 defined, to support freestanding compilers. This should fix the
11202 bug reported by Momchil Velkov in
11203 <http://mail.gnu.org/pipermail/autoconf/2002-November/014490.html>.
11205 * doc/autoconf.texi (Obsolete Macros): Fix typos (insert empty
11206 arg, AC_DEFINE -> AC_DEFINE_UNQUOTED) in documentation for

11218 \(.*\) match is too long and there is something more to be checked.
11219 <http://mail.gnu.org/pipermail/autoconf/2002-November/014524.html>
11221 2002-11-15 Akim Demaille <akim@epita.fr>

11237 Update from masters.
11239 2002-11-14 Akim Demaille <akim@epita.fr>
11241 * Makefile.maint: Sync with Bison, i.e.:
11242 (po-check): Scan .l and .y files instead of the
11243 .c and the .h files that they generate. This fixes the bug
11244 reported by Tim Van Holder in:
11245 <http://mail.gnu.org/pipermail/bison-patches/2002-November/001352.html>
11246 Look for N_ as well as for _. Try to avoid matching #define for
11250 2002-11-14 Akim Demaille <akim@epita.fr>
11252 * doc/autoconf.texi (C Compiler): Compiling several files at once.
11253 From Paul Eggert and Albert Chin-A-Young.
11255 2002-11-14 Akim Demaille <akim@epita.fr>
11257 * doc/autoconf.texi (C Compiler): Solitary backslashes.
11258 From Paul Eggert and Albert Chin-A-Young.
11260 2002-11-14 Kevin Ryde <user42@zip.com.au>
11262 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Initialize f=$1 rather
11263 than assigning in main, to avoid HP cc +O3 optimizing it away.
11265 2002-11-12 Peter Eisentraut <peter_e@gmx.net>
11267 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Add -q
11268 option. Process --recheck after parsing all options. Pass -q
11269 option to configure on --recheck.
11270 (AC_OUTPUT): Pass -q from configure to config.status.
11271 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Strip -q from
11272 arguments to record.
11273 * doc/autoconf.texi (config.status Invocation): Document
11274 config.status -q option.
11276 2002-11-07 Alexandre Duret-Lutz <adl@gnu.org>
11278 * bin/autoscan.in (scan_file): Scan Makefile.am too. Ignore
11279 Makefile.in if Makefile.am exists.
11280 (output): Strip `.am' from Makefiles. Don't
11281 output AC_CONFIG_FILES if no Makefiles were found.
11283 2002-11-07 Akim Demaille <akim@epita.fr>
11285 * Makefile.am (cvs_files): Add elisp-comp, mdate-sh.
11286 (local_updates): New.

11288 (local_updates): New.
11290 2002-11-06 Akim Demaille <akim@epita.fr>
11292 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY): Wrap the `f'
11293 declaration in extern "C" too.

11301 Reported by Ezra Peisach.
11303 2002-11-05 Akim Demaille <akim@epita.fr>
11305 * lib/autoconf/autoheader.m4 (_AH_TEMPLATE_OLD, _AH_VERBATIM_OLD):
11307 We _have_ to stop using the old compatibility scheme that tried to
11308 avoid useless backslashes because Libtool 1.4.3 contains a
11309 AC_DEFINE([error_t], [int],
11310 [Define to a type to use for \`error_t' if it is not
11311 otherwise available.])
11312 We _have_ to quote the single quote and backslashes with \. The
11313 old compatibility scheme saw that ` was backslashed, and therefore
11314 did not quote the single quote. Hence before this patch, Autoconf
11315 was not compatible with Libtool.
11317 2002-11-04 Paul Eggert <eggert@twinsun.com>
11319 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Set the following variables,

11336 (&autoreconf): here.
11337 ($help, $make, &parse_args, &autoreconf_current_directory):
11339 * doc/autoconf.texi (autoreconf Invocation): Adjust.
11341 2002-10-31 Bruno Haible <bruno@clisp.org>

11355 (AT_CHECK_ENV): Make sure the `state-ls.before file exists.
11357 2002-10-31 Akim Demaille <akim@epita.fr>
11359 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Use and display
11360 `$(MAKE)' instead of '${MAKE}' to emphasize that we refer to the
11361 Make variable, not a shell variable.
11362 Suggested by Bruno Haible.
11364 2002-10-31 Akim Demaille <akim@epita.fr>
11366 * bin/autom4te.in (load_configuration): Reject #args out of any
11369 2002-10-31 Akim Demaille <akim@epita.fr>
11371 * lib/autoconf/general.m4 (_AC_MSG_LOG_CONFTEST): New.
11372 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE, _AC_LINK_IFELSE)
11373 (_AC_RUN_IFELSE): Use it.
11374 * lib/autoconf/lang.m4 (_AC_COMPILER_OBJEXT):

11382 * doc/autoconf.texi (autom4te Invocation): Adjust.
11383 Suggested by Tim van Holder.
11385 2002-10-29 Paul Eggert <eggert@twinsun.com>
11387 * doc/autoconf.texi (Particular Functions): AC_FUNC_MALLOC and
11388 AC_FUNC_REALLOC check for compatibility with glibc, not POSIX.
11389 Problem reported by Bruno Haible.
11391 2002-10-29 Akim Demaille <akim@epita.fr>
11393 * doc/autoconf.texi (Header Templates): Put also in words what the
11394 pictures says to assist free style readers.
11395 (Customizing autom4te): s/--cache=/--cache /.
11397 2002-10-29 Akim Demaille <akim@epita.fr>
11399 * lib/autoconf/functions.m4 (_AC_FUNC_VFORK): Include stdlib.h and
11401 sparc_address_test returns void.
11402 Use it with an argument, as prototyped.
11405 2002-10-29 Akim Demaille <akim@epita.fr>
11407 * doc/autoconf.texi (Subdirectories): Cygnus dirs have

11706 Reported by Alexandre Duret-Lutz.
11708 * bin/autom4te.in (&parse_args): Do not prepend `--reload-state'

11713 (&up_to_date): If a file that was included according to the cache

11728 * lib/Autom4te/General.pm (&update_file): Use `verbose' to report
11729 if some file was changed instead of `print'.
11730 * bin/autoheader.in: Suggest AC_DEFINE with 3 args when needed.

11764 file name to enable parallel executions.
11765 From Sam Varshavchik.
11767 2002-10-08 Akim Demaille <akim@epita.fr>
11769 * bin/autoreconf.in (&autoreconf): Run autopoint before the first
11770 aclocal invocation, as Gettext macros might not be visible to
11772 Instead of blindly running autopoint, scan configure.ac (not the
11773 traces) for AM_GNU_GETTEXT_VERSION uses, as autopoint does.
11774 Reported by Paul D. Smith.
11776 2002-10-08 Paul Eggert <eggert@twinsun.com>
11778 Work around problems found when POSIXLY_CORRECT=1 is set.

11780 but it's how Perl getopt works.
11781 * bin/autom4te.in (parse_args): Configure GetOpt with
11783 * doc/autoconf.texi (Invoking autom4te):
11784 --warning -> --warnings.

11806 * tests/torture.at (Configuring subdirectories): Be robust to
11807 users who use config.site to require for a cache: in this case,
11808 the two last configure runs, using two different sets of
11809 arguments, trigger a legitimate error.

11848 (autoscan.list): New target --this file is no longer a source.

11856 tracking changes in autoscan.list.
11857 * lib/autoscan/autoscan.list (function): Strip comments, sort.

11875 2002-09-28 Akim Demaille <akim@epita.fr>
11877 From now on, autoscan files must always map a macro name to a

11880 * bin/autoscan.in (&init_tables): Reject entries with no macro at

11904 * lib/m4sugar/m4sh.m4 (AS_TMPDIR): $2 is the directory into which
11905 the tmpdir must be created.
11906 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Have the tmp
11907 dir be in the build tree, instead of $TMPDIR.
11909 2002-09-27 Akim Demaille <akim@epita.fr>
11911 * bin/autoscan.in: Improve the comments.
11912 (&parse_args): Drop obsolete undocumented options.
11913 (&output_kind): Output warnings.
11914 * lib/autoscan/functions: (dcgettext): Now trigger AM_GNU_GETTEXT.

11921 * doc/autoconf.texi (autoreconf Invocation): Likewise.
11923 2002-09-26 Akim Demaille <akim@epita.fr>
11925 Single suffix rules and seperated dependencies are not portable.
11927 * doc/autoconf.texi (Installation Directory Variables): Update.

11931 (ifnames, autoscan, autom4te): Un-factor into several rules.
11933 2002-09-25 Paul Eggert <eggert@twinsun.com>
11935 * BUGS (Interoperability bugs): New section. Mention libtool
11936 1.4.2, configure.ac, and AC_CONFIG_AUX_DIR interoperability bug.
11938 2002-09-24 Paul Eggert <eggert@twinsun.com>
11940 Fix a portability bug reported by Alexandre Duret-Lutz: Solaris 8
11941 make handles suffix-rules differently from GNU make.
11943 * bin/Makefile.am (SUFFIXES, .in): Remove.
11944 (autoconf autoheader autoreconf autoupdate ifnames autoscan autom4te):
11945 Move the body of the old .in rule here.
11947 2002-09-16 Akim Demaille <akim@epita.fr>
11949 i960 compilers create `b.out' files by default.
11950 Reported by Ralf Corsepius.
11952 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT): Remove b.out files.
11953 (_AC_COMPILER_EXEEXT_DEFAULT): Adjust to b.out.
11955 2002-09-13 Paul Eggert <eggert@twinsun.com>
11957 * doc/autoconf.texi (Particular Headers): Remove obsolete
11958 reference to `struct timezone' in the description of

11969 2002-09-13 Akim Demaille <akim@epita.fr>
11971 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Suggest
11972 reading config.log when the compiler is rejected.
11973 Suggested by Guido Draheim.
11975 2002-09-13 Akim Demaille <akim@epita.fr>
11977 * bin/autoreconf.in: Don't use Cwd::chdir, since in its internals
11978 (chdir_init) might hang when stat'ing mounted directories.
11979 Reported by Vance Shipley.
11981 2002-09-12 Akim Demaille <akim@epita.fr>
11983 * bin/autoscan.in (&parse_args): Pass a reference to the lists, not
11986 2002-09-12 Akim Demaille <akim@epita.fr>
11988 * doc/autoconf.texi (Defining Symbols): Present two different
11989 prototypes for AC_DEFINE and AC_DEFINE_UNQUOTED to emphasize the
11990 difference between 1 argument calls, and 2-3 argument calls.
11992 2002-09-12 Peter Eisentraut <peter_e@gmx.net>
11994 * doc/autoconf.texi: Review grammar and punctuation.
11996 2002-09-11 Paul Eggert <eggert@twinsun.com>

12000 (Defining Symbols): Explain that AC_DEFINE(var) defaults to 1, but
12001 AC_DEFINE(var,,description) does not; and the AC_DEFINE(var) case
12004 2002-09-11 Akim Demaille <akim@epita.fr>
12006 * doc/autoconf.texi (Questions): Rename as...
12008 (Defining Directories): New.
12010 2002-09-09 Akim Demaille <akim@epita.fr>
12012 * doc/autoconf.texi (Making testsuite Scripts): Update.
12013 Suggested by Nishio Futoshi.
12015 2002-09-09 Koji Arai <JCA02266@nifty.ne.jp>
12017 * doc/autoconf.texi (Making testsuite Scripts): Use `@@' where a
12018 plain `@' is wanted.
12020 2002-09-09 Akim Demaille <akim@epita.fr>
12022 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Keep the
12023 `duplicates', since the algorithm was too naive and could keep
12024 `--prefix=1 --prefix=2 --prefix=1' as `--prefix=1 --prefix=2', and
12025 keep `--prefix foo --prefix bar' as `--prefix foo bar'.
12026 Reported by Ralf Corsepius.
12027 * tests/torture.at (Configuring subdirectories): Exercise these
12030 2002-09-09 Akim Demaille <akim@epita.fr>
12032 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Use $srcdir when
12033 looking for a replacement file.
12034 * lib/autoconf/general.m4 (AC_CHECK_DECLS): Check that the
12035 directory is relative.
12036 * doc/autoconf.texi (Generic Functions): Clarify the replacement
12037 directory definition.
12038 Reported by Andreas Schwab and Jim Meyering.
12040 2002-09-06 Akim Demaille <akim@epita.fr>
12042 * doc/autoconf.texi (Setting Output Variables): Clarify what
12043 precious variables are.
12044 Suggested by Pontus Skoeld.
12046 2002-09-05 Akim Demaille <akim@epita.fr>
12048 * bin/Makefile.am (autoconf, autoheader, autoreconf, autoupdate)
12049 (ifnames, autoscan, autom4te): Since we don't only depend on
12050 configure.ac variables (such as VERSION etc.), but also on prefix
12051 and so forth, depend on Makefile, not configure.ac.
12052 Reported by Alexandre Duret-Lutz.
12053 * doc/autoconf.texi (Installation Directory Variables): Adjust.
12055 2002-09-05 Kevin Ryde <user42@zip.com.au>
12057 * doc/autoconf.texi (Limitations of Make): HP-UX trailing backslashes
12058 doesn't seem to be confined to ia64, just say "some versions".
12060 2002-09-04 Akim Demaille <akim@epita.fr>
12062 * Makefile.am, doc/Makefile.am: Remove pdf targets, handled by
12064 * Makefile.am (maintainer-clean-local): Remove.

12067 2002-09-03 Paul Eggert <eggert@twinsun.com>

12070 example for AC_CONFIG_COMMANDS_PRE. Problem reported by Marcus
12073 2002-09-03 Akim Demaille <akim@epita.fr>
12075 * configure.ac: Bump to 2.53d.
12076 * Makefile.am (AUTOMAKE_OPTIONS): Require 1.6c, i.e., CVS Automake
12077 as of today, on Automake's team suggestion.
12079 2002-09-03 Akim Demaille <akim@epita.fr>
12083 2002-09-02 Akim Demaille <akim@epita.fr>
12085 * bin/autom4te.in (parse_args): Don't honor AUTOM4TE_PATH and
12087 * configure.ac: Disable SITE_MACRO_DIR.
12089 2002-09-02 Jim Meyering <meyering@lucent.com>
12091 * doc/autoconf.texi (AC_SYS_POSIX_TERMIOS): Reflect renaming: s/am/ac/,
12092 i.e., change am_cv_sys_posix_termios to ac_cv_sys_posix_termios.
12093 Also, tweak grammar: s/make sure to/be sure to/.
12095 2002-09-02 Paul Eggert <eggert@twinsun.com>
12097 * doc/autoconf.texi (Limitations of Builtins): Explain why logical
12098 directory names are generally preferable to physical names.
12100 2002-09-02 Akim Demaille <akim@epita.fr>
12102 * lib/Autom4te/General.pm (&update_file): s/die/error/.
12103 Reported by Raja R. Harinath.
12104 * bin/autoheader.in, bin/autoreconf.in, bin/autoscan.in,
12105 * bin/autoupdate.in: Use error instead of die.
12107 2002-09-01 Paul Eggert <eggert@twinsun.com>
12109 * tests/mktests.sh (ac_exclude_egrep, au_exclude_egrep): Use
12110 ordinary shell concatenation rather than echo+tr+sed command that
12111 runs afoul of a long-line-related sed bug in Solaris 8.
12113 * bin/autoheader.in (parse_args): --warning -> --warnings.
12115 * bin/autoconf.as: Work even if "ls" outputs "FOO not found" to
12116 stdout, as traditional "ls" does.
12117 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT,
12118 _AC_COMPILER_EXEEXT_O): Likewise.
12119 * doc/autoconf.texi (Limitations of Usual Tools): Add "ls".
12121 * bin/autoconf.as: Add --prepend-include option. This patch was
12122 applied to bin/autoconf.in in the 2002-07-17 patch by Mark D. Roth,
12123 but bin/autoconf.in is generated automatically from bin/autoconf.as.
12125 * bin/autoconf.in, configure: Regenerate.
12127 * doc/autoconf.texi (Special Shell Variables): Mention
12128 ENV, MAIL, MAILPATH, PS1, PS2, PS4. Index PWD.
12130 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Unset ENV, MAIL,
12131 MAILPATH and set PS1, PS2, PS4 to default values, to work
12132 around bug in pre-3.0 UWIN ksh reported by Bruce Lilly.
12133 For LC_ALL etc, first try to set to "C" as POSIX requires and as
12134 the Autoconf documentation specifies; fall back to "unset" only if
12135 this fails. Use a shell for-loop for this rather than an m4 loop,
12136 to shorten the output script.
12138 2002-08-30 Paul Eggert <eggert@twinsun.com>
12140 * doc/autoconf.texi (Special Shell Variables): Mention POSIX
12141 1003.1-2001's requirements for CDPATH. Give a simpler workaround
12142 for the CDPATH problem. Document PWD.
12143 (Limitations of Builtins): Document the problem that "cd $foo" and
12144 "ls $foo" may refer to different directories in shells conforming
12145 to POSIX 1003.1-2001. Use PS1 rather than CDPATH for "unset"
12146 example, since the old example is now out of date.
12148 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Reject FOO if "cd
12149 FOO" and "ls FOO" talk about different directories; this catches
12150 problems when POSIX 1003.1-2001 "cd" fails due to symlink
12153 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Use AS_UNSET instead
12154 of rolling our own unset.
12155 (_AS_PREPARE): $as_unset CDPATH instead of AS_UNSETting it, since
12156 in practice we needn't worry about CDPATH if unset doesn't work.
12158 * Makefile.in, aclocal.m4, bin/Makefile.in,
12159 config/Makefile.in, doc/Makefile.in, lib/Makefile.in,
12160 lib/Autom4te/Makefile.in, lib/autoconf/Makefile.in,
12161 lib/autoscan/Makefile.in, lib/autotest/Makefile.in,
12162 lib/emacs/Makefile.in, lib/m4sugar/Makefile.in, man/Makefile.in,
12163 tests/Makefile.in: Regenerate with Automake 1.6.3.
12165 * config/config.guess, config/config.sub, config/mkinstalldirs:
12168 * configure: Regenerate with self.
12170 2002-08-30 Kevin Ryde <user42@zip.com.au>

12180 2002-08-29 Akim Demaille <akim@epita.fr>
12182 * lib/Autom4te/General.pm (&xqx): New.
12183 (&xsystem): Use WIFEXITED and WEXITSTATUS instead of decoding $? by
12184 hand, which is not portable.
12186 * bin/autom4te.in: Use them.
12187 Use &error instead of die.
12188 * tests/m4sugar.at (m4_warn, m4_require: circular dependencies):
12191 2002-08-17 Paul Eggert <eggert@twinsun.com>
12193 * lib/autoconf/fortran.m4 (AC_PROG_F77): Remove fc from the
12194 default list of compilers to try, since it was long ago superseded
12195 by the ksh fc builtin. Suggested by Steven G. Johnson.
12197 2002-07-31 Alexandre Duret-Lutz <duret_g@epita.fr>
12199 * doc/autoconf.texi (Invoking autom4te): End the option table,
12200 fixing a bug introduced by the previous patch.
12201 (Limitations of Make): Add a 'target lookup' subentry in the
12202 'VPATH' entry. Rewrite all `make' occurences as `@command{make}'.
12204 2002-07-29 Mark D. Roth <roth@feep.net>
12206 * bin/autom4te.in: Remove --include-envvar and --site-macro-subdir
12207 options and use $AUTOM4TE_PATH.
12208 * doc/autoconf.texi: Remove documentation of autom4te
12209 --include-envvar and --site-macro-subdir options and document
12210 use of $AUTOM4TE_PATH.
12211 * lib/autom4te.in: Remove --include-envvar and --site-macro-subdir
12212 arguments from each language section.
12214 2002-07-29 Paul Eggert <eggert@twinsun.com>
12216 * doc/install.texi: Include copyright symbol in copyright notice.
12218 * Makefile.am (MAKEINFO): Remove; it's a user-specified macro.
12220 (AM_MAKEINFOFLAGS): New macro.
12221 * doc/Makefile.am (MAKEINFO, AM_MAKEINFOFLAGS): Likewise.
12222 * Makefile.am (INSTALL): Use the new macros.
12223 Use -o rather than --output, since "missing" does not grok --output.
12225 2002-07-25 Alexandre Duret-Lutz <duret_g@epita.fr>
12227 * doc/autoconf.texi (Limitations of Make): Escaped newlines in
12228 comments do not always work. Never trust the exit status of
12231 2002-07-24 Kevin Ryde <user42@zip.com.au>
12233 * doc/autoconf.texi (Limitations of Make, Making testsuite Scripts):
12234 Untabify, since tabs are not enjoyed by texi2dvi and makeinfo.
12236 2002-07-23 Paul Eggert <eggert@twinsun.com>
12238 * lib/m4sugar/m4sh.m4 (_AS_PATH_SEPARATOR_PREPARE):
12239 Use PATH="/nonexistent;.", not PATH=".;.", as FreeBSD ksh2002
12240 apparently treats PATH="nonexistent" as if it contained ".".
12241 Bug reported by Stefan `Sec' Zehl.
12243 2002-07-22 Alexandre Duret-Lutz <duret_g@epita.fr>
12245 * doc/autoconf.texi (Limitations of Make): Mention the special
12246 handling of the obj/ directory by BSD make.

12292 * lib/autoconf/functions.m4 (AC_FUNC_FORK): Don't set
12293 ac_cv_func_fork_works before running _AC_FUNC_FORK, do it if the
12294 latter was not run.
12296 2002-07-17 Akim Demaille <akim@epita.fr>
12298 * lib/Autom4te/General.pm (find_file): Browse the directories in

12513 2002-05-16 Paul Eggert <eggert@twinsun.com>
12515 AC_FUNC_FNMATCH now tests only for POSIX compatibility.
12516 AC_FUNC_FNMATCH_GNU also tests for GNU extensions.
12517 Both macros now accept an optional source-dir arg.
12518 New macro AC_GNU_SOURCE to define _GNU_SOURCE.
12520 * NEWS: Document this.
12521 * doc/autoconf.texi (Particular Functions, UNIX Variants): Likewise.
12523 * lib/autoconf/functions.m4 (_AC_FUNC_FNMATCH): New macro.
12524 (AC_FUNC_FNMATCH): Use it. Test only for POSIX conformance,
12525 not for GNU extensions; this undoes part of the 2000-11-03 change,
12526 reverting to 2.13-compatible behavior.

12534 * lib/autoconf/headers.m4 (AC_HEADER_TIOCGWINSZ):
12535 Don't require AC_SYS_POSIX_TERMIOS. The test is unnecessary,

12537 Bug reported by Stephen Gildea.
12539 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
12540 If prototypes are supported, use them to check this at compile-time,
12541 instead of trying to check it at run-time. If we must do a run-time
12542 check, assume that setvbuf is standard when cross-compiling, as
12543 nonstandard setvbuf occurs only on ancient and unlikely hosts.
12544 Bug reported by Paul D. Smith.
12546 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Add optional
12547 argument specifying location of getloadavg.c. This removes a
12548 FIXME. This idea was taken from Jim Meyering's implementation in
12550 * doc/autoconf.texi (Particular Functions): Document this.
12551 Also, mention HAVE_NLIST_H rather than NLIST_STRUCT, since
12552 that's what the code does; this fixes a bug reported by

12558 autopoint instead of gettextize.
12559 ($uses_alocal): Rename as...

12568 2002-04-29 Paul Eggert <eggert@twinsun.com>
12570 * bin/autoreconf.in (autoreconf): Don't age aclocal.m4's input
12571 files to be 1 second older; just set them to be the same time.
12572 Also, sleep 1 second after the first aclocal, to work around
12573 problems with sub-second time stamps on the input files.
12575 2002-04-29 Thien-Thi Nguyen <ttn@gnu.org>
12577 * doc/autoconf.texi: Mention "set -e -x" lossage

12586 2002-04-29 Akim Demaille <akim@epita.fr>
12588 * tests/m4sh.at (LINENO): If testsuite itself is rewritten because
12589 of lack of $LINENO support, then the test will compare the $LINENO
12590 in testsuite vs. the lineno in the test file. This is wrong, of
12592 Be sure to protect it.
12593 Reported by Patrick Welche.
12595 2002-04-25 Akim Demaille <akim@epita.fr>
12597 * doc/autoconf.texi (Obsolete Macros): Typo.
12598 Reported by Vladimir Volovich.
12600 2002-04-25 Akim Demaille <akim@epita.fr>
12602 * bin/autoreconf.in (autoreconf): Don't let aclocal.m4 be older
12603 than some of the input files, hence, on the second run of aclocal,
12604 if some of its input are younger, make them older.
12605 Suggested by Paul Eggert.
12607 2002-04-25 Akim Demaille <akim@epita.fr>
12609 * doc/autoconf.texi (Limitations of Usual Tools): sed and `!'.

12618 (_AC_INIT_PREPARE): Use them to log them.
12619 (_AC_SUBST, _AC_SUBST_SED_PROGRAM): Remove.
12620 (AC_SUBST, AC_SUBST_FILE): Instead of buliding the
12621 _AC_SUBST_SED_PROGRAM, store the list of output files/variables in
12622 _AC_SUBST_FILES and _AC_SUBST_VARS.
12623 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Adjust.
12625 2002-04-24 Akim Demaille <akim@epita.fr>
12627 * bin/autoreconf.in (autoreconf): Run automake after autoconf and
12628 autoheader, so that automake does not complain about a missing

12877 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Unset ENV and BASH_ENV
12878 when reinvoking the shell, to work around problems with installers
12879 who put strange things like "cd" commands in their environments.
12881 2002-03-19 Akim Demaille <akim@epita.fr>
12883 * tests/semantics.at (AC_C_BIGENDIAN): s/unknow/unknown/.
12886 2002-03-19 Akim Demaille <akim@epita.fr>
12888 * bin/autoscan.in (scan_file): Specify the location in `&used'
12892 2002-03-19 Akim Demaille <akim@epita.fr>

12895 From Nishio Futoshi.
12897 2002-03-19 Akim Demaille <akim@epita.fr>
12899 * lib/m4sugar/m4sugar.m4 (m4_define_default, m4_fst, m4_map): New.
12901 2002-03-18 Paul Eggert <eggert@twinsun.com>
12903 * doc/autoconf.texi (Programming in M4sh): Add AS_MKDIR_P.
12904 (Limitations of Usual Tools): Add mkdir section.
12906 * lib/m4sugar/m4sh.m4 (_AS_MKDIR_P_PREPARE): New macro.
12907 (AS_MKDIR_P): Require it. Use mkdir -p if available, falling
12908 back on AS_DIRNAME to compute prefixes otherwise; this is
12909 roughly what mkinstalldirs does. That way, we need not have
12910 our own filename disassembler. The old disassembler did not
12911 work with Solaris 8 dtksh, which is ksh Version M-12/28/93d.
12913 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP):
12914 Create at_test_all by a series of assignments,
12915 not by a single assignment of a long string. The latter causes ksh
12916 version 11/16/88g to silently misbehave on OpenServer 5.0.6a,
12917 presumably because of a buffer overrun.
12919 2002-03-14 Paul Eggert <eggert@twinsun.com>
12921 * lib/autotest/general.m4 (at_times_skip):
12922 Renamed from at_times. Now a boolean.
12923 ksh93 Version M-12/28/93d doesn't like 'x=times; $x'; it
12924 says 'times: not found'.
12926 2002-03-14 Akim Demaille <akim@epita.fr>
12928 * bin/autoreconf.in (&study_gettextize): New.
12929 (&autoreconf): Handle newest gettextize.

12953 2002-03-11 Andreas Schwab <schwab@suse.de>

12967 2002-03-08 Akim Demaille <akim@epita.fr>
12969 * Makefile.am (AUTOMAKE_OPTIONS): 1.6.
12971 2002-03-08 Akim Demaille <akim@epita.fr>
12973 * bin/autom4te.in (&handle_m4): Do not foreach with `$_' as it
12974 aliases the actual variables, and modifications of the former
12977 2002-03-08 Akim Demaille <akim@epita.fr>
12979 * bin/autom4te.in (&handle_m4): Protect us from corrupted file
12980 because of C-c: have m4 output in tmp files, then mv them.

13003 * doc/autoconf.texi (AC_LIBOBJ vs. LIBOBJS): New.
13004 * lib/autoconf/general.m4 (AC_INIT): More informative error
13005 message for LIBOBJ.
13007 2002-03-04 Akim Demaille <akim@epita.fr>

13012 2002-03-04 Akim Demaille <akim@epita.fr>
13014 * doc/autoconf.texi (Transforming Names): Equality between target
13015 and host is irrelevant.
13016 (Specifying Names, Canonicalizing): Remove all references to the
13017 backward compatibility hooks. Rather, collect them all into...
13018 (Hosts and Cross-Compilation): this new section.
13019 * doc/install.texi (System Type): Ditto.
13020 * lib/autoconf/general.m4 (AC_CANONICAL_HOST): Explicitly state
13021 that `--host' implies cross-compilation.
13023 2002-03-04 Akim Demaille <akim@epita.fr>
13025 * doc/autoconf.texi (Evaluation Macros): New.
13026 * lib/m4sugar/m4sugar.m4 (m4_lquote): Remove, it is totally
13028 (_m4_foreach): Define the variant with immediate evaluation so
13029 that it contains exactly the items, not an expression which
13030 evaluation is the current item.
13031 (m4_re_string, m4_re_word): Don't over quote them.
13033 2002-03-04 Akim Demaille <akim@epita.fr>
13035 Instead of having stacking `shift's evaluated at the end, let
13036 `foreach' loops immediately evaluate them.
13038 * lib/m4sugar/m4sugar.m4 (m4_quote, m4_dquote): Use $@ rather than
13039 $*. This is the n-th time I change my mind, but hopefully this is
13042 (m4_text_wrap): Use m4_foreach, which is finally correct _and_
13044 (m4_foreach_quoted, m4_car_quoted, _m4_foreach_quoted): Remove, as
13045 it was only a hack for m4_text_wrap.
13046 (m4_car2): Remove, replaced by...
13048 (_m4_foreach): Adjust.
13049 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Adjust, and use
13050 m4_bpatsubst for clarification.

13101 Fix Autoconf PR/207:
13102 AC_PREFIX_PROGRAM fails with dashed program names
13104 * lib/autoconf/general.m4 (AC_PREFIX_PROGRAM): Just use a fresh

13141 2002-02-05 Akim Demaille <akim@epita.fr>
13143 * tests/Makefile.am (check_SCRIPTS): Use it, instead of WRAPPERS,

13166 optional are the sum of the previous files on the command line'.
13167 Also, pass `--reload-state=' on them, so...
13168 (handle_m4): don't.

13170 (M4sh): Rely on M4sugar.

13208 2002-01-28 Akim Demaille <akim@epita.fr>
13210 * lib/autotest/general.m4 (AT_INIT): Don't be ridiculous: adjust
13211 AUTOTEST_PATH *after* it was set.
13212 Don't put `.' in the PATH: the user should be precise and `./' if
13213 needed. In addition, given that the test suite does some `cd', if
13214 `.' is in the path, the `tested programs' sections will report
13215 programs found in the test suite's directory, while during the
13216 tests (performed in their own directory), these programs are no
13217 longer visible. In other words, the results is confusing and
13219 * tests/m4sh.at: Adjust: don't rely on `.' being in the PATH.

13265 * bin/autom4te.in (parse_args): Don't use
13266 Autoconf::General::getopt with non valid options.

13270 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Initialize

13288 * tests/Makefile.am (package.m4): New.
13289 EXTRA_DIST it since its a source.
13291 2002-01-06 Akim Demaille <akim@epita.fr>

13294 of PACKAGE_NAME, PACKAGE_TARNAME, PACKAGE_VERSION, PACKAGE_STRING,
13295 and PACKAGE_BUGREPORT from here...
13296 (_AC_INIT_DEFAULTS): to here, since it is unrelated to the
13298 (_AC_INIT_PREPARE): AC_DEFINE these symbols.
13299 * lib/autotest/general.m4: Use AT_PACKAGE_*, not PACKAGE_*.
13300 (AT_INIT): No longer catch `^PACKAGE_(BUGREPORT|STRING)$'.
13301 * tests/tools.at (autoheader): Adjust.

13323 2001-12-14 Akim Demaille <akim@epita.fr>
13325 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): We cleaning up the
13326 trailing files, don't apply `-rf' to files which might not be
13327 created by configure (core, core.*, and *.core), but just `rm -f'.
13328 Suggested by Jonathan Kamens.
13330 2001-12-14 Aaron M. Ucko <amu@alum.mit.edu>

13367 Remove $filepath, useless.

13369 variables, they are really part of the tokens.
13370 Split the input line on spaces and then look for tokens.
13371 Now autoscan ceases to ask for AC_PROG_LEX for the package Bison
13372 because of `lex$U.$(OBJEXT)'.

13390 2001-11-26 Akim Demaille <akim@epita.fr>
13392 * bin/autoscan.in (&scan_c_file): Better parsing of CPP
13394 (&scan_sh_file): Remove a duplicate pattern.
13395 (&check_configure_ac): Use long options.
13396 * lib/autoscan/headers (alloca.h): Check with AC_FUNC_ALLOCA.
13398 2001-11-26 Akim Demaille <akim@epita.fr>
13400 * bin/autoscan.in (scan_c_file): Fix the handling of C comments.
13401 Before, having a line containing the opening of a multi line
13402 comment made the whole line be ignored.
13404 2001-11-26 Akim Demaille <akim@epita.fr>
13406 * doc/autoconf.texi (Using an Autotest Test Suite): New.
13407 (testsuite Scripts): Be one of its subsection.
13408 (Autotest Logs): New.
13410 2001-11-26 Akim Demaille <akim@epita.fr>
13412 Test groups are now run two directories deeper.
13414 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Replace srcdir,
13415 top_srcdir and top_builddir with at_srcdir, at_top_srcdir and
13417 * lib/autotest/general.m4 (AT_INIT): Compute srcdir,
13418 top_srcdir, builddir and top_builddir.
13419 Use `at_*dir' relatively to the directory containing the
13420 suite, use `*dir' when relatively to the current group dir.
13422 2001-11-25 Joseph S. Myers <jsm28@cam.ac.uk>
13424 * doc/autoconf.texi, TODO, lib/autoconf/fortran.m4,
13425 lib/autoconf/functions.m4, lib/autoconf/headers.m4,
13426 tests/atgeneral.m4, tests/tools.at, tests/atspecific.m4: Fix
13429 2001-11-22 Alexandre Duret-Lutz <duret_g@epita.fr>
13431 * doc/autoconf.texi (Using System Type): Add an example of `case
13432 $host' usage so people quit using `case $target' everywhere.
13434 2001-11-22 Akim Demaille <akim@epita.fr>
13436 * doc/autoconf.texi (Installation Directory Variables): Englishoes
13437 spotted by Jim Meyering.
13439 2001-11-16 Paul Eggert <eggert@twinsun.com>
13441 This patch implements a `long double' suggestion by Oliver Kiddle.
13443 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C)): Make the array
13444 static, to catch errors if the value isn't known at compile-time
13445 and the compiler supports dynamic arrays. Change its name from
13446 `_array_' to `test_array' to avoid potential name clashes.
13447 (AC_C_LONG_DOUBLE): Make it a compile-time test, not a run-time
13448 test. Do not define HAVE_LONG_DOUBLE if `long double' is no
13449 better than double. Catch a bug in GCC 2.95.2 x86.
13450 * doc/autoconf.texi (C Compiler): Document the above.
13453 2001-11-13 Akim Demaille <akim@epita.fr>
13455 * tests/m4sh.at (LINENO): Protect from autom4te's substitution by
13457 * tests/tools.at: Don't protect dnl, AT_DATA_M4SH does.
13459 2001-11-13 Akim Demaille <akim@epita.fr>
13461 * lib/autotest/general.m4 (AT_INIT): After having run the test
13462 group, go back to the initial directory, not to at_suite_dir.
13464 2001-11-13 Akim Demaille <akim@epita.fr>
13466 * tests/atspecific.m4 (AT_DATA_M4SUGAR, AT_DATA_M4SH)
13467 (AT_DATA_AUTOCONF): Also protect @&t@ from autom4te.
13468 (AT_CHECK_AUTOCONF, AT_CHECK_AUTOHEADER): Pass no --include
13470 (AT_CHECK_CONFIGURE): Use absolute paths.
13471 (_AT_CHECK_AC_MACRO): Create aclocal.m4 with AC_STATE_SAVE in it.
13472 The problem is still the old one: there is no means in M4 (that I
13473 know about) to create a defining macro, because there is no means
13474 to create `$1' etc., therefore, the defining macro ``swallows''
13475 all the arguments meant to the defined macro.
13477 2001-11-13 Akim Demaille <akim@epita.fr>
13479 * tests/atspecific.m4 (AT_DATA_AUTOCONF): New.
13480 (AT_CONFIGURE_AC): Output the definition of AC_STATE_SAVE in
13482 * tests/aclocal.m4: Remove, as it is no longer used.
13484 2001-11-13 Akim Demaille <akim@epita.fr>
13486 * lib/autotest/general.m4: Change `tests?' into `groups?' in
13487 variable names when referring to a single test group, or to
13488 `suite' when referring to the whole test suite.
13489 `at_last_test' is removed: m4 compute at_format itself.
13490 (at_stdout, at_stder1, at_stderr): New variables.
13491 (AT_CHECK): Use them.
13493 2001-11-13 Akim Demaille <akim@epita.fr>
13495 * lib/autotest/general.m4 (AT_INIT): Be sure to put `.', relative,
13497 Create `testsuite.dir/003/run' instead of `testsuite.003'.
13498 Do it as soon as a test fails, don't wait till the end of the test
13500 Don't remove $as_me.[0-9]*, since these files no longer exist.
13502 2001-11-13 Akim Demaille <akim@epita.fr>
13504 * tests/tools.at: Use absolute paths, since we are no longer run
13507 2001-11-13 Akim Demaille <akim@epita.fr>
13509 Now that tests are running in their own private dir, there is no
13510 need to list the files to remove at the end of tests groups.
13512 * lib/autotest/general.m4 (_AT_CLEANUP_FILE, AT_CLEANUP_FILES):
13513 (AT_data_files, at_data_files): Remove.
13514 (AT_CLEANUP, AT_DATA): Simplify.
13516 Remove the group dir if !debug && !failed.
13517 * tests/atspecific.m4: Adjust.
13519 2001-11-13 Akim Demaille <akim@epita.fr>
13521 Start a new layout for Autotest: `testsuite' creates
13522 `testsuite.dir' in which the at-check-line etc. files are to be
13523 found, and `testsuite.dir/003' where the test group 3 is run.
13525 * lib/autotest/general.m4 (AT_INIT): at_tests_dir,
13526 at_check_line_file, at_format, at_test_normalized, at_group_dir
13528 Create the directories.
13529 Use absolute paths for at- files.
13530 (AT_CHECK): Adjust.
13532 2001-11-11 Michael Matz <matz@kde.org>
13534 * m4sugar.m4 (_m4_foreach): Make it linear instead quadratic.
13536 (m4_car): Properly quote arguments.
13538 2001-11-13 Akim Demaille <akim@epita.fr>
13540 * tests/aclocal.m4 (AC_STATE_SAVE): s/LIBOBJS/LIB@&t@OBJS/ to cope
13541 with stricter rules on LIBOBJS.
13543 2001-11-12 Paul Eggert <eggert@twinsun.com>
13545 * lib/autoconf/c.m4 (AC_C_PROTOTYPES): Define __PROTOTYPES too.
13546 * doc/autoconf.texi (C Compiler): AC_C_PROTOTYPES now defines
13549 2001-11-12 Akim Demaille <akim@epita.fr>
13551 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT): Use AC_CHECK_FUNCS.
13553 2001-11-12 Akim Demaille <akim@epita.fr>
13555 * lib/autoconf/c.m4, lib/autoconf/fortran.m4,
13556 * lib/autoconf/functions.m4, lib/autoconf/general.m4,
13557 * lib/autoconf/headers.m4, lib/autoconf/libs.m4,
13558 * lib/autoconf/programs.m4, lib/autoconf/specific.m4,
13559 * lib/autoconf/types.m4: When invoking AC_DEFINE and friends,
13560 specify to what the macro should be defined (typically to 1).
13562 2001-11-12 Akim Demaille <akim@epita.fr>
13564 * lib/autoconf/functions.m4 (AC_FUNC_STRTOD): AC_SUBST POW_LIB.
13567 2001-11-12 Akim Demaille <akim@epita.fr>
13569 * lib/autoconf/programs.m4 (_AC_PROG_LEX_YYTEXT_DECL): Use
13570 AC_TRY_EVAL to run $LEX, not AC_TRY_COMMAND. This validates the
13571 definition used by Automake where LEX is +/- "${missing} lex" and
13572 `missing' itself contains variables.
13574 2001-11-12 Akim Demaille <akim@epita.fr>
13576 * lib/autotest/general.m4 (AT_INIT): Push KILL at the end.
13577 Now that M4sh pushes BODY, the comments were output at the end of
13580 2001-11-08 Akim Demaille <akim@epita.fr>
13582 * bin/autoreconf.in (&autoreconf): Run aclocal before tracing, so
13583 that we can trace macros from aclocal.m4.
13584 Trace AC_PROG_LIBTOOL, not AM_PROG_LIBTOOL, since the latter is
13585 obsoleted, and redirect to the former anyway.
13586 Reported by Ralf Corsepius.
13588 2001-11-08 Akim Demaille <akim@epita.fr>
13590 * bin/autoreconf.in (&autoreconf): AC_CONFIG_SUBIDRS are to be
13591 processed only if present.
13592 * tests/torture.at (Configuring subdirectories): Use autoreconf
13593 instead of successive calls to autoconf.
13594 Add a nonexistent subdirectory to exercise the patch above.
13595 Reported by Ralf Corsepius.
13597 2001-11-08 Kevin Ryde <user42@zip.com.au>
13599 * doc/autoconf.texi (Limitations of Usual Tools): Note HP-UX cc
13600 doesn't accept .S files.
13602 2001-11-07 Akim Demaille <akim@epita.fr>
13604 * lib/m4sugar/m4sugar.m4 (m4_pattern_forbid): Accepts $2.
13605 * lib/autoconf/general.m4 (AC_INTI): Forbid LIBOBJS.
13606 (_AC_LIBOBJ): s/LIBOBJS/LIB@&t@OBJS/.
13607 * bin/autom4te.in (warn_forbidden): New.
13608 (handle_output): Use it.
13609 Read m4_pattern_forbid with messages.
13611 2001-11-05 Akim Demaille <akim@epita.fr>
13613 * bin/autom4te.in (--normalize): Remove.
13614 * lib/autom4te.in: Adjust.
13616 2001-11-05 Akim Demaille <akim@epita.fr>
13618 * tests/Makefile.am (testsuite): Rename this target as...
13619 ($(TESTSUITE)): this.
13622 2001-11-05 Alexandre Duret-Lutz <duret_g@epita.fr>
13624 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): When removing
13625 the --prefix option, also remove it's argument.
13627 2001-11-05 Akim Demaille <akim@epita.fr>
13629 * doc/autoconf.texi (testsuite Invocation): Update.
13630 (Writing testsuite.at): Update.
13632 2001-11-03 Akim Demaille <akim@epita.fr>
13634 * doc/autoconf.texi: s/@code/@command/ where appropriate.
13636 2001-11-03 Akim Demaille <akim@epita.fr>
13638 * lib/Autom4te/General.pm: (&catfile, &canonfile)
13639 (&file_name_is_absolute): New, wrappers around routines from
13641 Use and export them.
13642 (&find_configure_ac): Optionally take a directory where to look at.
13643 * bin/autoreconf.in (&parse_args): Trim the configure.ac part of
13645 Default @ARGV to `.', not find_configure_ac.
13646 (&autoreconf): Argument is a directory.
13647 Trace AC_CONFIG_SUBDIRS and schedule the subdirs for autoreconf'ing.
13648 * doc/autoconf.texi (autoreconf Invocation): Update.
13650 2001-11-03 Akim Demaille <akim@epita.fr>
13652 * lib/Autom4te/General.pm (@export_vars, @export_subs)
13653 (@export_forward_subs): New.
13654 Add basename, dirname, and fileparse.
13656 * bin/autoreconf.in (&autoreconf): Fix call to fileparse.
13657 Don't look for aclocal flags if we already know aclocal is not
13659 Move aclocal.m4t only if it exists.
13660 Reported by Ezra Peisach.
13662 2001-11-03 Akim Demaille <akim@epita.fr>
13664 * bin/autoreconf.in (&parse_args): Work only on the configure.ac
13665 passed on command line, defaulting to ./configure.ac if present.
13666 (&maybe_autoreconf, File::Find): Remove, unused.
13667 (&autoreconf): If autoconf is not used, don't try to trace.
13669 2001-11-02 Akim Demaille <akim@epita.fr>
13671 * configure.ac: Bump to 2.52g.
13673 2001-11-02 Akim Demaille <akim@epita.fr>
13677 2001-11-02 Akim Demaille <akim@epita.fr>
13679 * config/config.guess, config/config.sub, doc/standards.texi:
13680 * config/lispdir.m4: Update from masters.
13681 * configure.ac: Bump to 2.52f.
13683 2001-11-02 Akim Demaille <akim@epita.fr>
13685 * bin/autoreconf.in (&autoreconf): Set `$aclocal_flags' to ''.
13686 Don't run aclocal when aclocal.m4 is not from aclocal.
13688 Don't run libtoolize and gettextize if --install is not given.
13690 2001-11-01 Paul Eggert <eggert@twinsun.com>
13692 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): _AS_CR_PREPARE needs to
13693 be invoked before _AS_LINENO_PREPARE.
13694 (_AS_LINENO_PREPARE): Use as_cr_digits and as_cr_alnum rather
13695 than character ranges.
13697 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Fix NLS before
13698 invoking AS_BASENAME. Set the locale variables to 'C' if
13699 possible, as POSIX requires this to get the traditional
13701 * doc/autoconf.texi (Special Shell Variables): Describe the above.
13703 2001-10-31 Paul Eggert <eggert@twinsun.com>
13705 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): Do not surround body
13706 with {}, as that triggers a bug in Bash 2.05.
13708 (_AS_LINENO_PREPARE): Use Sed rather than
13709 Awk. Fix the sed prepass to work even if there are multiple
13710 instances of $LINENO on the same line. Do not substitute for
13711 other variables like $LINENOT. Do not check file dates; such a
13712 check is unreliable on sufficiently fast machines, and removing
13713 the check makes the code simpler and more reliable. Check for
13714 output and chmod failures.
13716 * doc/autoconf.texi (Special Shell Variables): Document
13719 2001-10-31 Akim Demaille <akim@epita.fr>
13721 * tests/Makefile.am (atconfig): Remove this target, Automake
13724 2001-10-31 Akim Demaille <akim@epita.fr>
13726 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Do not
13727 AC_CONFIG_FILES(atlocal) as it means a file atlocal.in *must* be
13728 provided, while it is optional.
13729 * configure.ac: Adjust.
13731 2001-10-26 Paul Eggert <eggert@twinsun.com>
13733 * NEWS, README, configure.ac, lib/Autom4te/General.pm,
13734 lib/Autom4te/Struct.pm:
13735 Require Perl 5.005_03 instead of just 5.005, as some tests fail
13738 * doc/autoconf.texi (Special Shell Variables): Document some
13739 more LINENO gotchas, particularly with respect to the Awk+Sed hack.
13741 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): New macro.
13742 (_AS_LINENO_PREPARE): Use it instead of shell eval, since
13743 eval $LINENO is not portable in practice.
13745 2001-10-24 Akim Demaille <akim@epita.fr>
13747 * lib/Autom4te/General.pm (backname): New.
13749 2001-10-24 Akim Demaille <akim@epita.fr>
13751 * m4/: Remove, merged into...
13754 2001-10-23 Tim Van Holder <tim.van.holder@pandora.be>
13756 * doc/autoconf.texi (Shellology): Mention the problems with bash
13757 2.05's use of ANSI quoting in its `set' builtin.
13759 2001-10-22 Paul Eggert <eggert@twinsun.com>
13761 * lib/autoconf/functions.m4 (AC_FUNC_STRERROR_R):
13762 Rename ac_cv_func_strerror_r_works to ac_cv_func_strerror_r_char_p,
13763 and rename HAVE_WORKING_STRERROR_R to STRERROR_R_CHAR_P, since
13764 POSIX decided to standardize on the int flavor of strerror_r.
13765 Always do char* test, as there's no reason not to.
13766 Assign to a char* var, to catch strerror_r that returns int*.
13768 * doc/autoconf.texi (Particular Functions):
13769 Document the above changes. Also, document the fact that
13770 AC_FUNC_STRERROR_R defines HAVE_DECL_STRERROR_R.
13772 * NEWS: Mention HAVE_WORKING_STRERROR_R -> STRERROR_R_CHAR_P.
13774 2001-10-20 Akim Demaille <akim@epita.fr>
13776 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): The name of
13777 the executable was missing from the log.
13779 2001-10-20 Akim Demaille <akim@epita.fr>
13781 * lib/Autom4te/General.pm (&update_file): If destination is
13782 unchanged, remove the source.
13783 (&up_to_date_p): Don't be verbose, be debug.
13784 * bin/autoreconf.in: No longer support --m4dir.
13785 (&autoreconf): Display the full path of the configure.ac we are
13787 Trace it only once.
13788 Be sure to honor --force with gettextize.
13789 Always run aclocal.
13790 * doc/autoconf.texi: Adjust.
13792 2001-10-20 Akim Demaille <akim@epita.fr>
13794 * bin/autoheader.in ($localdir, $m4, $SIMPLE_BACKUP_SUFFIX):
13796 * bin/autoreconf.in (&autoreconf): Do not run gettextize when
13797 `intl' is already present, as it refuses unless --force.
13798 (&parse_args): Use -I, --include instead of the old Autoconf
13800 ($localdir, $autoconf_dir): Remove.
13802 (&maybe_autoreconf): New, to preserve $_ for File::Find.
13804 2001-10-19 Jens Petersen <petersen@redhat.com>
13806 * lib/autoconf/programs.m4 (AC_PROG_AWK): Prefer gawk to mawk.
13807 * doc/autoconf.texi (Particular Programs): Likewise.
13809 2001-10-19 Akim Demaille <akim@epita.fr>
13811 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Name the generated
13812 file in @configure_input@.
13813 Don't mention `automatically' in addition to `generated'.
13814 * tests/torture.at (#define header templates): Adjust.
13816 2001-10-19 Akim Demaille <akim@epita.fr>
13818 * lib/emacs/autoconf-mode.el, lib/emacs/autotest-mode.el: In a
13819 comment, explain how to install automatic mode selection.
13822 2001-10-19 Ezra Peisach <epeisach@zif.mit.edu>
13824 * bin/autoreconf.in (autoreconf): Display the path to the
13825 configure.ac being studied.
13827 2001-10-18 Paul Eggert <eggert@twinsun.com>
13829 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Cast sizeof to unsigned
13830 long, to work around a bug in the HP C compiler version HP92453-01
13833 * lib/m4sugar/m4sh.m4 (AS_DIRNAME): Use 'dirname' if that works.
13834 (AS_BASENAME_EXPR): New macro.
13835 (AS_BASENAME_SED): Do not assume GNU sed semantics.
13836 (AS_BASENAME): Use 'basename' if that works; then try 'expr';
13837 and fall back on 'sed' only if the other two fail. This makes
13838 AS_BASENAME act more like AS_DIRNAME.
13839 (as_me): Shell-quote the argument of AS_BASENAME, in case $0
13840 contains white space.
13841 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR):
13842 Use AS_DIRNAME, since I think it's now DOS-friendly.
13843 * tests/m4sh.at (DIRNAME_TEST): New arg $3.
13844 Allow "dirname //FOO" to return either / or //, as POSIX allows
13847 2001-10-10 Akim Demaille <akim@epita.fr>
13849 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Recognize
13850 `a_out.exe' for OpenVMS 7.1, DEC C 5.5 compiler, via GNV.
13853 2001-10-10 Akim Demaille <akim@epita.fr>
13855 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N_PREPARE): m4_defun, not
13856 m4_define, since...
13857 (_AS_ECHO_N): AS_REQUIREs it.
13859 2001-10-10 Akim Demaille <akim@epita.fr>
13861 * lib/autoconf/general.m4 (_AC_INCLUDES_DEFAULT_REQUIREMENTS)
13862 (AC_INCLUDES_DEFAULT): Move to...
13863 * lib/autoconf/headers.m4: here.
13864 * lib/autoconf/types.m4: Comment changes.
13865 * doc/autoconf.texi: Specify where the default includes are used
13866 in the macro prototypes.

13877 --debug, not when --verbose.
13878 * lib/autom4te.in (Autoreconf-preselections): New.
13879 (Autoconf): Use it.

14294 * lib/autotest/general.m4: Englishoes.

14299 * doc/autoconf.texi (Common Shell Constructs): New node,

14309 to expr, by parenthesizing initial integers that might be negative.
14311 * doc/autoconf.texi (Particular Functions): AC_FUNC_GETPGRP
14312 now merely checks whether it is an error to pass an argument
14315 * lib/autoconf/functions.m4 (_AC_FUNC_GETPGRP_TEST): Remove.
14316 (AC_FUNC_GETPGRP): Don't bother with a runtime test. Just check
14317 whether it is a (compile-time) error to pass an argument to
14318 getpgrp. This simpler test supports the revised documentation,
14319 and is all that AC_FUNC_GETPGRP's users really need.

14335 Add test for AS_BASENAME.
14336 * lib/m4sugar/m4sh.m4: Fix AS_BASENAME so that it passes the previous
14337 added test. It now correctly handles /1/2/3/, returning '3' not ''.
14338 Added AS_BASENAME_SED to make the interface the same as AS_DIRNAME.
14339 * tests/base.at: Fixed the expected responses. The old ones were
14341 * lib/autoconf/general.m4: Fixed AC_PREFIX_PROGRAM, it now behaves as
14342 the documentation claims it should (and how it behaved in 2.13).
14344 2001-09-18 Akim Demaille <akim@epita.fr>
14346 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): No INIT-CMDS in
14347 the AC_CONFIG_COMMANDS invocation.
14348 This also solves the name clash problems.
14349 Don't set the package's ID.
14350 * lib/m4sugar/Makefile.am (version.m4): Revamp.
14351 No longer to be shipped.

14355 Use `m4_PACKAGE_STRING'.
14356 * lib/autotest/general.m4 (AT_INIT): N-th signature change: now
14357 the only optional argument is the name of the test suite.
14358 Expect `package.m4' to define the package signature.
14359 * lib/autom4te.in (Autotest): Add `package.m4?'.
14360 * tests/Makefile.am (package.m4): New.
14361 * tests/suite.at: ifnames is a victim.

14375 Allow expression to return any value that can fit into unsigned long
14376 (not int, as before). Check for output errors.

14380 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):
14381 Always include <stdio.h> and <stdlib.h>. Evaluate

14383 fprintf "%d" only after ensuring the argument is of type 'int'.
14384 Reported by Wayne Chapeskie <waynec@spinnaker.com>.
14386 2001-09-17 Paul Eggert <eggert@twinsun.com>
14388 Fix bug reported by Paul Townsend on AIX 4.3.3.0 with CFLAGS=-O4
14389 or CFLAGS=-O5. In that case, the linker has a relaxed view of
14390 fatal errors, and AC_CHECK_LIB causes it to include libraries even
14391 when they don't exist.
14393 * lib/autoconf/headers.m4 (AC_HEADER_DIRENT): Use AC_SEARCH_LIBS,
14394 not AC_CHECK_LIB, so that we don't use -ldir or -lx if we don't
14397 * lib/autoconf/specific.m4 (AC_ISC_POSIX): Replace the old, crufty
14398 version with the version used by fileutils 4.1, except use
14399 AC_SEARCH_LIBS, not AC_CHECK_LIB, so that we don't use -lcposix if

14444 * lib/autotest/general.m4 (AT_INIT): Create and remove
14445 `$as_me.[0-9]+' instead of `debug-[0-9]+.sh', so that multiple

14450 * tests/mktests.sh: Don't output banners for empty test files.

14549 to avoid GCC warnings.
14552 2001-09-05 Akim Demaille <akim@epita.fr>

14556 2001-09-05 Akim Demaille <akim@epita.fr>
14558 Be ready to handle filenames as stupid as `dnl.at', for if even
14559 the maintainer is dumb enough to do that...
14561 * lib/autotest/general.m4 (AT_SETUP, AT_LINE): Demonstrates your
14562 excellence in M4 quotation: consider `__file__' is active.
14564 And BTW, when invoking m4, pass the --include in the right order:
14567 * bin/autom4te.in, bin/autoupdate.in: Use reverse when kingtal to

14595 New, extracted from main.
14596 Use IO::File wherever possible.

14629 * doc/autoconf.texi (Quadrigraphs): Document `@&t@'.
14630 (testsuite Scripts): There is no such thing as `atconfig.in'.

14635 * lib/Autom4te/General.pm (&find_file): Browse the includes in the
14638 2001-08-31 Akim Demaille <akim@epita.fr>

14713 Map --localdir, --autoconf-dir onto it.
14714 Forward autom4te's options instead of interpreting them.
14715 * bin/autoconf.in, bin/autoheader.in (AC_MACRODIR, autoconf_dir):
14716 There is no such envvar since the inception of autom4te.cfg.
14717 * bin/autom4te.in (&parse_args): Uniquify `@include'.

14738 * lib/Autom4te/General.pm (&find_peer): Remove.
14739 * lib/autotest/general.m4 (AT_INIT): `AUTOTEST_PATH=a:b' gives
14740 `abuild:asrc:bbuild:bsrc', not `abuild:bbuild:asrc:bsrc'.
14741 * man/Makefile.am: Let help2man rely on PATH instead of trying to
14742 find the executables for it.
14743 * tests/Makefile.am: Major cleanup. Too lazy to document...
14744 * tests/atlocal.in: Remove all the obscure envvar manipulations.
14746 * tests/atspecific.m4, tests/tools.at: Passing --localdir is
14747 indeed related to running the test suite, while passing
14748 --autoconf-dir and others is related to running non installed
14749 Autoconf executables. So don't do that, leave it to...

14751 * tests/autoscan: New.
14752 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): Don't

14768 * bin/autom4te.in (&handle_output): s/@__@/@&t@/.
14769 Suggested by Paul Eggert.
14771 2001-08-29 Akim Demaille <akim@epita.fr>
14773 * Makefile.maint (do-po-update): Wget refuses to overwrite files:
14774 download in a tmp dir.
14776 2001-08-29 Akim Demaille <akim@epita.fr>
14778 * lib/autotest/general.m4: s/AT-devnull/devnull/ since there are

14797 * lib/autotest/general.m4: Use
14798 foo=`(command) 2>/dev/null`
14800 foo=`command` 2>/dev/null
14801 (at-devnull): Rename as...
14802 (AT-devnull): this.
14803 (--clean): Remove AT-* files too.

15315 2001-08-11 Alexandre Duret-Lutz <duret_g@epita.fr>
15317 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Handle ACTION-IF-TRUE,
15318 ACTION-IF-FALSE, and ACTION-IF-UNKNOWN.
15319 * doc/autoconf.texi (C Compiler Characteristics): Update
15320 documentation for AC_C_BIGENDIAN.
15322 2001-08-11 Alexandre Duret-Lutz <duret_g@epita.fr>
15324 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Guess endianness by grep'ing
15325 magic values from an object file when cross-compiling.
15326 Based on code by Guido Draheim <Guido.Draheim@gmx.de>.
15328 2001-08-10 Akim Demaille <akim@epita.fr>
15330 * bin/autom4te.in (&handle_output): Don't use `grep' with side
15332 Suggested by Russ Allbery.
15334 2001-08-10 Ralf Corsepius <corsepiu@faw.uni-ulm.de>
15336 * lib/autoconf/general.m4 (_AC_OUTPUT_SUBDIRS): Propagate the
15337 current $prefix to the sub-configures.
15339 2001-08-09 Tim Van Holder <tim.van.holder@pandora.be>
15341 * lib/autoconf/lang.m4: Ignore *.xSYM when looking for an executable
15342 extension (needed on BeOS). Reported by Guido van Rossum.
15344 2001-08-09 Akim Demaille <akim@epita.fr>
15346 * bin/autom4te.in ($icache): Load it only if older than autom4te.
15348 2001-08-07 Akim Demaille <akim@epita.fr>
15350 * lib/autotest/general.m4 (AT_INIT): All the `at-*' are to be
15352 (at-setup-line): Huh? Be a variable `at_setup_line', not a file.
15353 No need to remove the files before and after the each test, before
15354 each test and at the end of the suite is enough.
15355 Display only the children `times', not the shell's.
15356 If the test failed or was skipped, at-times is not available.
15358 2001-08-07 Akim Demaille <akim@epita.fr>
15360 Always produce testsuite.log, including when there are no
15361 failures. This helps getting information on skipped tests, and
15362 duration of the tests. Err, implement the latter btw.
15364 * lib/autotest/general.m4 (AT_INIT): Set up fd 6 for the log.
15365 Dump information on the first run of each test.
15366 (AT_CLEANUP): Create `at-times' containing the duration of the
15369 2001-08-07 Akim Demaille <akim@epita.fr>
15371 The use of `dumpstat' revealed that `len' was used although it
15372 should not. m4_text_wrap was using it, but in the Autoconf world
15373 where it is legal. Hence (i) test M4sh in its own world, not
15374 Autoconf's, and (ii), ahem, fix the bug :)
15376 * lib/autotest/general.m4: Be sure the set good quotes, as tracing
15377 does not like `' instead of [].
15378 (AT_INIT): Forbid `^_?AT_'.
15379 And don't output such tokens.
15380 * tests/Makefile.am (CLEANFILES): Add `script', `script.s4g',
15381 `script.as', and `autom4te.cache'.
15382 Remove `empty' and `macro' which are no longer used.
15383 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): New.
15384 * tests/m4sugar.at: Use it.
15385 * lib/m4sugar/m4sugar.m4: Use `m4_len' not `len'.
15387 2001-08-07 Akim Demaille <akim@epita.fr>
15389 * bin/autoconf.in, bin/autoheader.in: --force, -f is a new option.
15391 2001-08-07 Alexandre Duret-Lutz <duret_g@epita.fr>
15393 * bin/autom4te.in (handle_output): Typo in quadrigraph substitution.
15395 2001-08-04 Akim Demaille <akim@epita.fr>
15397 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA, AC_FUNC_ERROR_AT_LINE)
15398 (AC_FUNC_FSEEKO, AC_FUNC_OBSTACK): Use AC_LANG_IFELSE, not
15400 * lib/autoconf/headers.m4 (AC_HEADER_MAJOR): Likewise.
15401 * lib/autoconf/fortran.m4 (_AC_LANG_PROGRAM_C_F77_HOOKS)
15402 (AC_F77_MAIN): Likewise.
15404 2001-08-04 Akim Demaille <akim@epita.fr>
15406 Don't rely on M4sugar outputting the patterns in files, since we
15407 might process the output _without_ running m4, hence without these
15410 * lib/m4sugar/m4sugar.m4 (m4_init): No need for `m4_tmpdir'.
15411 * bin/autom4te.in (@Request::includes): Remove, unused.
15412 (@Request::source): Rename as...
15413 (@Request::input): this.
15414 (@preselect): Add `m4_pattern_forbid' and `m4_pattern_allow'.
15415 (&handle_output): Fetch the patterns from the traces.
15416 `$forbidden' and `$allowed' are constant: use m//o.
15417 (&handle_m4): M4sugar no longer wants `m4_tmpdir'.
15418 (m4_pattern_forbid, m4_pattern_allow): Adjust for tracing only.
15420 2001-08-04 Akim Demaille <akim@epita.fr>
15422 `autoconf && autoheader' is sped up. Now, speed up `autoheader &&
15423 autoconf', i.e., in addition to caching traces, cache the output.
15425 * bin/autom4te.in (Request::cache): Rename as...
15426 (Request::id): this.
15427 ($cache, $icache, $tcache, $ocache): New.
15428 (&handle_m4): Save M4 output in the cache instead of $tmp.
15429 (&handle_output): Adjust.
15430 (&up_to_date_p): Check that the output cache is up to date too.
15431 (top level): Run `&handle_m4' iff force or the cache is invalid.
15432 Run `&handle_output' if the output cache is more recent.
15434 2001-08-04 Akim Demaille <akim@epita.fr>
15436 * bin/autom4te.in ($force): New.
15437 (&parse_args, &print_usage): -f, --force is a new option.
15438 (&handle_output): CPP directives might have spaces after `#'.
15439 (&parse_args): The first file only can be frozen.
15441 2001-08-04 Akim Demaille <akim@epita.fr>
15443 Don't let autom4te compute the `include' traces several times:
15444 first check that the trace cache file is up to date, and then
15445 compare its timestamp with that of the output.
15447 * bin/autom4te.in, bin/autoupdate.in, bin/autoscan.in: Normalize
15448 the preamble. Don't require 5.005 as Autom4te::General does it,
15449 and better yet (use `use', not `require'!).
15450 * lib/Autom4te/Struct.pm: Rename the last occurrences of
15451 Class::Struct as Autom4te::Struct.
15452 * lib/Autom4te/General.pm (File::stat): Use it.
15453 (&mtime): New, export it.
15454 * bin/autom4te.in: Use it.
15455 Declare `$req' is invalid if it is outdated.
15456 Don't declare it valid before saving it if something went wrong.
15458 2001-08-04 Akim Demaille <akim@epita.fr>
15460 Autom4te shall not encode Autoconf data, and preselecting traces
15461 must be proposed to the users.
15463 * bin/autom4te.in (@required_trace): Remove.
15465 (&parse_args, &print_usage): -p, --preselect is a new option.
15466 (&up_to_date_p): Adjust.

15469 2001-08-04 Akim Demaille <akim@epita.fr>
15471 * tests/tools.at (autoconf --trace: user macros): Check traces on
15472 macros invoked without arguments, and macros invoked with multiple
15475 2001-08-03 Alexandre Duret-Lutz <duret_g@epita.fr>
15477 * bin/autom4te.in (handle_traces): Fix rewriting of traces without
15480 2001-08-03 Akim Demaille <akim@epita.fr>
15482 * bin/autoconf.in ($@): Work around the usual sh bug.
15485 2001-08-03 Akim Demaille <akim@epita.fr>
15487 Clean up the handling of the M4 builtins tracing exception.
15489 * bin/autom4te.in (Request::request): Don't complete M4 builtins
15491 (@m4_builtins): Rename as...
15492 (@m4_builtin): this.
15493 (%m4_builtin_alternate_name): New.
15494 (&parse_args): Complete the trace requests with alternate names.
15495 (&handle_traces): Hence no longer do it here.

15500 * doc/autoconf.texi (Redefined M4 Macros): Document m4_exit,
15501 m4_if, and m4_wrap.

15505 * lib/m4sugar/m4sugar.m4 (m4_init): Also forbid `_m4_*' tokens.
15506 (m4_divert_pop): Dump the whole diversion stack when a diversion
15508 * bin/autom4te.in (&handle_output): Remember of the first
15509 occurrence of a possibly undefined macro, not the last.
15510 Complain about the possibly undefined macros in the same order as
15511 the appear in the output.
15512 * lib/autoconf/Makefile.am (autoconf.m4f): List its dependencies.
15513 * tests/tools.at (autoconf: forbidden tokens, basic)
15514 (autoconf: forbidden tokens, exceptions): No longer sort
15515 autoconf's stderr, as it is now deterministic.
15516 Check that `dnl' is caught.
15518 2001-08-01 Akim Demaille <akim@epita.fr>
15520 * configure.ac: Bump to 2.52c.

15537 * bin/autoconf.in, bin/autom4te.in, bin/autoupdate.in: Remove your
15538 `END', as `Autom4te::General::END' will be triggered.
15539 * bin/autoupdate.in, bin/autoscan.in: Improve error messages accuracy.
15540 * bin/autoupdate.in (File::Compare, File::Copy): Use them instead of
15541 system to run `mv', `rm', and `cmp'.

15545 * lib/Autom4te/General.pm (&unique): New.
