1080 On MinGW, substitution of CR and 0xFF fails.
1081 * tests/torture.at (Substitute and define special characters):
1082 MinGW awk cannot handle 0xFF, and on MinGW, the test does the
1083 wrong thing for CR.
1085 2008-03-04 Eric Blake <ebb9@byu.net>
1087 Pull in recent maintainer improvements from coreutils.

1167 Cover more potentially problemtic file names. Use the new
1168 functions.
1170 Properly handle funny file names for headers in config.status.
1171 The test suite did not cover this bug because the code was not
1172 quoting properly the arguments of `rm -f' (which "fails" silently)
1173 as well as the arguments of `diff' (whose output was redirected to
1174 /dev/null so we couldn't see its error message).
1175 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Properly quote the
1176 file names passed to `rm' and `diff'.
1177 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):

1243 Fix more autotest regressions.
1244 * lib/autotest/general.m4 (AT_LINE): Fix regression from

1262 bug.
1264 * doc/autoconf.texi (Limitations of Builtins) <.>: Mention bash
1265 bug.
1267 2008-01-28 Eric Blake <ebb9@byu.net>
1269 Fix regression in handling VAR=VALUE arguments to testsuite.
1270 * lib/autotest/general.m4 (AT_INIT) <PARSE_ARGS_END>: Detect
1271 leading = as invalid. Defer use of command-line variable
1272 assignments...
1273 <PREPARE_TESTS>: ...here, after atconfig has been sourced. Fix
1274 regression in sourcing files.
1275 * tests/autotest.at (Using atlocal): New test to catch this.
1276 (Debugging a successful test, Choosing where testsuite is run):
1277 Use correct shell.

1281 * doc/autoconf.texi (Limitations of Usual Tools) <grep>: Document
1282 BSD behavior on binary input.
1284 Minor testsuite improvements.

1286 forks when sanitizing PATH. Always output machine information,
1287 not just when atconfig was located.
1289 Add 'testsuite -C dir'.
1290 * lib/autotest/general.m4 (_AT_ARG_OPTION): Move missing argument
1291 detection...
1292 (AT_INIT) <PARSE_ARGS_END>: ...here, since -k always takes
1293 argument.
1294 <DEFAULTS>: Delay computation of variables based on $at_dir...
1295 <PREPARE_TESTS>: ...to here, since -C can change $at_dir.
1296 <TESTS>: Re-invoke via absolute name, since -C may be in effect.
1297 <PARSE_ARGS>: Parse new option.
1298 <HELP_TUNING>: Document it.
1299 * tests/autotest.at (Choosing where testsuite is run): New test
1300 for this feature.
1301 (Keywords and ranges): Add test for missing -k argument.
1302 * NEWS: Document this.
1303 * doc/autoconf.texi (testsuite Invocation): Likewise.
1305 2008-01-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1307 * build-aux/config.guess, build-aux/config.sub,
1308 build-aux/texinfo.tex: Sync from gnulib.
1309 * doc/fdl.texi, doc/make-stds.texi, doc/standards.texi:
1310 Likewise.
1312 2008-01-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1314 * doc/autoconf.texi (Particular Programs): Do not mention the
1315 Autoconf version in which the AC_PROG_INSTALL change was done.
1316 Suggested by Paul Eggert.
1318 2008-01-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1320 Fix --help=recursive with multiple AC_CONFIG_SUBDIRS.
1321 * lib/autoconf/general.m4 (_AC_INIT_HELP): If, for recursive help
1322 mode, we change to the source directory, also set $ac_pwd so we
1323 do not go back to the build tree for the next config subdir.
1324 * tests/torture.at (Deep Package): Extend test to contain two
1325 config subdirs on the top level.
1327 Fix parallel `maintainer-check'.
1328 * Makefile.am (maintainer-check-tests): Depend on `all'.
1329 Use `$(MAKE) $(AM_MAKEFLAGS)' instead of plain `make'.
1330 * tests/Makefile.am (maintainer-check-c++, maintainer-check-posix):
1331 Likewise.
1332 (maintainer-check): Serialize the testsuite runs.
1334 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE2): Accept `+'

1339 `install -c file1 file2 dir' works.
1340 * doc/autoconf.texi (Particular Programs): Document this.

1350 Reported by Reuben Thomas.
1352 2008-01-15 Eric Blake <ebb9@byu.net>

1356 2008-01-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1358 * tests/Makefile.am (noinst_SCRIPTS): Renamed from
1359 check_SCRIPTS. Building the wrappers for `all' allows help2man
1360 to use them for the manpages.
1361 Report by Benoit Sigoure.
1363 * bin/autoreconf.in: Discard stderr for $autoconf/$aclocal --help.
1365 2007-12-16 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1367 Fix some write failure cases in Autotest.

1377 * lib/m4sugar/m4sugar.m4 (m4_expansion_stack_push, _m4_defun_pro)
1378 (_m4_defun_pro_outer, _m4_defun_epi, _m4_defun_epi_outer)
1379 (m4_require): Use m4_do, not m4_join.
1381 Fix some whitespace tests on cygwin.
1382 * tests/tools.at (autom4te and whitespace in file names): Restore
1383 font-lock. Create $TMPDIR before it might be used.
1385 Fix spurious testsuite failure with M4 1.4.11.
1386 * tests/local.at (AT_CHECK_M4): Cater to new m4 error message.
1388 Optimize AC_REQUIRE.
1389 * lib/m4sugar/m4sugar.m4 (m4_expansion_stack_push, _m4_defun_pro)

1391 (m4_require): Avoid extra macro calls.
1393 2007-12-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1395 * tests/torture.at (srcdir): Fix quoting.
1397 Do not pass top_srcdir to configure scripts in testsuite.
1398 * tests/autotest.at (srcdir propagation): Copy install-sh to
1399 source tree.
1400 (my only test): Drop setting of `top_srcdir'.
1401 * tests/base.at (Input/Output): Likewise.
1402 * tests/local.at (AT_CONFIGURE_AC): Copy install-sh,
1403 config.guess, and config.sub to test source tree.
1404 Drop AC_CONFIG_AUX_DIR setting.
1405 (AT_CHECK_CONFIGURE): Drop setting of `top_srcdir'.
1406 * tests/torture.at (Substitute a 2000-byte string): Drop
1407 AC_CONFIG_AUX_DIR setting, copy install-sh to test source tree.
1408 (Substitute a newline, datarootdir workaround): Likewise.
1409 (Define a newline): Adjust for linenumber changes in configure.ac.
1410 * tests/foreign.at (Libtool): Adjust comment to reflect changes.
1412 * tests/semantics.at (AC_PATH_PROGS_FEATURE_CHECK): Skip test
1413 if `pwd` contains whitespace.
1415 Quote $abs_top_srcdir in tests.

1417 * tests/tools.at (Syntax of the shell scripts): Likewise.
1419 * tests/m4sh.at (LINENO): Quote $0.
1421 Fix testsuite program wrapper for whitespace in `pwd`.
1422 The problem here is that the usual mantra is that command
1423 variables can contain arguments, thus we cannot just escape
1424 $AUTOCONF, $AUTOM4TE etc. The compromise is to put the
1425 $top_builddir/tests directory early in $PATH, so that the
1426 wrappers are found by their plain name.
1427 * tests/wrapper.as: Put $testdir early in $PATH.
1428 (AUTOCONF, AUTOHEADER, AUTOM4TE): Set to plain command names.
1430 Proper config.status --file/--header and $srcdir escaping.
1431 * lib/autoconf/status.m4 (_AC_OUTPUT_MAIN_LOOP): Quote special
1432 characters in $ac_file_inputs.
1433 (_AC_OUTPUT_FILE, _AC_OUTPUT_HEADER): eval $ac_file_inputs
1434 accordingly.

1436 (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS): Extend test.
1438 Fix Autotest for whitespace in `pwd`.
1439 * lib/autotest/general.m4 (AT_INIT)
1440 <at_func_create_debugging_script, Driver Loop>:
1441 Quote $at_group_dir.
1442 * tests/autotest.at (whitespace in absolute testdir): New test.
1444 * lib/autom4te.in: Quote @datadir@.
1446 Proper file name escaping in Autoconf programs and Perl modules.
1447 This includes escaping of characters special to the shell
1448 as well as special to Perl, e.g., leading `<' or `>'.
1449 For example, when $file starts with `>', `open ">$file"'
1450 wrongly tries to append to a different file.
1451 * bin/autoconf.as: Fix quoting for autom4te options.
1452 * lib/Autom4te/General.pm (shell_quote): New function, taken
1453 from coreutils, written by Jim Meyering.
1454 (mktmpdir): Use it.
1455 * bin/autom4te.in (files_to_options, handle_m4): Use shell_quote
1456 and open_quote.
1457 * bin/autoreconf.in (parse_args): Likewise.
1458 * bin/autoscan.in (main): Likewise.
1459 * bin/autoupdate.in (main): Likewise.
1460 * bin/autoheader.in: Likewise, fixing old insufficient escaping.
1461 * bin/ifnames.in: Likewise, XFile usage fixes.
1462 * tests/tools.at (autom4te and whitespace in file names): Extend
1463 test. Test twice, with special characters allowed on w32, and the
1464 rest. Test leading and trailing whitespace, for `open_quote'.
1465 (autotools and whitespace in file names): New, analogous test.
1466 Reported by Paul Eggert and Benoit Sigoure, additional suggestions
1467 by Russ Allbery and Eric Blake.
1469 Sync from Automake.
1470 * lib/Autom4te/Channels.pm, lib/Autom4te/Configure_ac.pm,
1471 lib/Autom4te/Struct.pm, lib/Autom4te/XFile.pm: Likewise.
1472 * lib/Autom4te/FileUtils.pm (open_quote): New function.
1473 (update_file, contents): Use it.
1475 * Makefile.am (autom4te-update): Rewrite for git.
1477 2007-12-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1479 * doc/autoconf.texi (autom4te Invocation, Autom4te Cache): Fix typos.
1481 Fix copyright years.
1482 * Makefile.am, doc/install.texi, lib/autoconf/fortran.m4,

1485 2007-12-04 Eric Blake <ebb9@byu.net>
1487 Manually resync with gnulib, since 'make cvs-update' no longer works.
1488 * build-aux/config.guess: New upstream version.
1489 * build-aux/config.sub: Likewise.
1491 When using older automake, don't downgrade build-aux/texinfo.tex.
1492 * configure.ac (AM_INIT_AUTOMAKE): Add no-texinfo.tex option.
1493 * doc/Makefile.am (TEXINFO_TEX): Add.
1495 2007-11-27 Paul Eggert <eggert@cs.ucla.edu>
1497 Fix AC_C_BIGENDIAN bug caused by new awk method of substitution.
1498 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Don't comment out the
1499 #undef as this runs afoul of our new way of creating config.h.
1500 Problem reported by Jim Meyering in
1501 <http://lists.gnu.org/archive/html/autoconf-patches/2007-11/msg00164.html>.

1505 Fix autom4te for unusual characters in input file names.
1506 * bin/autom4te.in (files_to_options): Quote active characters
1507 for the shell.
1508 * tests/tools.at (autom4te and white space in file names):
1509 New test.
1511 * doc/autoconf.texi (Limitations of Usual Tools) <awk>:
1512 Document that Tru64 awk always splits $0.
1514 2007-11-24 Stepan Kasal <kasal@ucw.cz>
1516 * lib/autotest/general.m4 (AT_INIT): Do not extract the
1517 `#AT_STOP_...' line at the end of each test.
1519 2007-11-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1521 * lib/autotest/general.m4 (AT_INIT): For awk line number
1522 extraction script, ensure `$at_group' has a defined value
1523 even for the empty set, and properly quote its usage inside
1524 the awk script.
1526 2007-11-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1528 * doc/autoconf.texi (Shell Functions): New chapter. Document
1529 IRIX sh $0 issue in functions, move content from ...
1530 (Portable Shell): ... here.
1531 (Shell Script Compiler): Note that shell functions are not
1532 totally unportable any more.
1534 2007-11-22 Stepan Kasal <kasal@ucw.cz>
1535 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1537 * lib/autotest/general.m4 (AT_INIT): Exit awk script after
1538 extracting the line numbers of the last needed test.
1540 2007-11-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1542 * lib/autotest/general.m4 (AT_INIT) <at_func_create_debugging_script>:
1543 Fix quoting.
1545 2007-11-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1547 Fix IRIX testsuite debugging failures: $0 in functions.
1548 * lib/autotest/general.m4 (AT_INIT) <at_func_create_debugging_script>:
1549 Do not use $0 inside a function, as IRIX sh will set that to the
1550 function name rather than the script invocation name.
1552 2007-11-19 Paolo Bonzini <bonzini@gnu.org>
1553 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1555 * lib/autotest/general.m4 (at_func_test): Use cached line numbers
1556 to extract test scripts.
1557 (AT_INIT): Extract and cache test script line numbers.
1559 2007-11-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1561 * lib/autotest/general.m4: Revert 2007-11-15 patch and
1562 subsequent fixups; the awk -> here-document conversion trashes
1563 performance too much with AIX sh.
1565 2007-11-18 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1567 * tests/local.at: Do not test m4, perl with AT_TESTED.
1569 Diagnose and guard against write errors dealing with config.status.
1570 The general idea is this: all write failures from `configure'
1571 writing `config.status' are indicated by $ac_write_error, which
1572 is only checked at the end. This is safe because config.status
1573 code is not executed before the file is complete. Other write
1574 failures, be they inside config.status, or in sub shell/awk
1575 scripts spawned from configure or config.status, typically need
1576 earlier checking, as their results are used right afterwards.
1577 * lib/autoconf/status.m4 (AC_OUTPUT): Initialize `ac_write_fail'
1578 before writing config.status, check afterwards.
1579 (_AC_OUTPUT_FILES_PREPARE, _AC_OUTPUT_FILE)
1580 (_AC_OUTPUT_HEADERS_PREPARE,_AC_OUTPUT_CONFIG_STATUS):
1581 Set `ac_write_error' for write failures to config.status. Barf
1582 upon write failures to temporary files.
1583 Adjust note about closing and reopening the here-document.
1584 (_AC_OUTPUT_HEADER, _AC_OUTPUT_LINK, _AC_OUTPUT_COMMAND)
1585 (_AC_OUTPUT_MAIN_LOOP): Likewise, adjust note about closing and
1586 reopening the here-document.
1587 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
1588 Ensure `ac_write_error' does not escape into config.status.
1589 Also, add a couple of code paths not yet exercised in the test
1590 suite: a config file with input from stdin, and a config header
1591 output to stdout.
1592 Suggestion for catching write errors by Bruno Haible.
1594 2007-11-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1596 Avoid error with Tru64 awk and testsuite lines with many words.
1597 * lib/autotest/general.m4 (AT_INIT): In the awk script that
1598 reads the testsuite, set the field separator to an unusual value,
1599 in order to not run over the limit of 199 fields. Tru64 4.0D awk
1600 even splits the input if $i, i>0, was never accessed in the script.
1602 Revert 2007-10-17 change.
1603 * TODO: Multiline args in config files and headers mean something
1604 different and are not fixed, see
1605 <http://lists.gnu.org/archive/html/autoconf-patches/2007-05/msg00017.html>
1606 Report by Stepan Kasal.
1608 * doc/autoconf.texi (Generic Programs): Fix typo.
1610 2007-11-16 Stepan Kasal <kasal@ucw.cz>
1612 AC_*_TOOL does not canonicalize the prefix
1613 * doc/autoconf.texi (Generic Programs): Do not say that
1614 the *_TOOL macros canonicalize, they simply use the `host_alias'.
1616 2007-11-16 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1618 Diagnose write errors in config.status instantiations.
1619 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE)
1620 (_AC_OUTPUT_HEADER, _AC_OUTPUT_MAIN_LOOP): Bail out
1621 on write errors.
1622 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
1623 Extend test to also check for some write error failures, using...
1624 <AT_CHECK_CONFIG_CREATION_NOWRITE>: ...this new macro.
1625 Report by Bruno Haible.
1627 Indentation fixups.
1628 * lib/autotest/general.m4 (AT_INIT) <at_func_log_failure>: Fix
1629 indentation.
1630 (_AT_CHECK): Use less indentation, to save space.
1632 2007-11-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1634 Add witness macro for @top_build_prefix@ substitution.
1635 * lib/autoconf/status.m4 (_AC_HAVE_TOP_BUILD_PREFIX): New macro.
1636 (_AC_OUTPUT_FILE): Mention it here.
1638 2007-11-15 Paolo Bonzini <bonzini@gnu.org>
1639 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1641 * lib/autotest/general.m4 (at_func_test): Remove.
1642 (AT_INIT): Pre-extract test groups into separate files.
1643 (AT_CLEANUP): Source pre-extracted file instead of calling at_func_test.
1644 Remove at-test-source files together with the $at_group_dir.
1645 * tests/autotest.at (Long test source lines): New test.
1647 2007-11-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1649 Shell functions and variables may share a namespace.
1650 * doc/autoconf.texi (Portable Shell): Mention Solaris sh
1651 limitation.
1653 2007-11-14 Paul Eggert <eggert@cs.ucla.edu>
1655 * lib/autoconf/types.m4 (_AC_TYPE_LONG_LONG_SNIPPET): Make comment match
1656 gnulib.
1658 2007-11-14 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1660 * lib/autoconf/status.m4: Fix a couple of comment typos.
1662 * lib/m4sugar/m4sh.m4 (AS_TMPDIR): Use $as_me, not $me.
1664 2007-11-13 Jim Meyering <meyering@redhat.com>
1666 Clean up the rule to create "expr".
1667 * tests/Makefile.am (expr): Don't redirect directly to target.
1668 Redirect just once, not for each echo statement.
1669 Use $@, not literal "expr".
1671 2007-11-13 Paul Eggert <eggert@cs.ucla.edu>
1673 Don't worry about preprocessor when testing long long.
1674 See: http://lists.gnu.org/archive/html/bug-gnulib/2007-11/msg00075.html
1675 * doc/autoconf.texi (Preprocessor Arithmetic): New section.
1676 (AC_TYPE_LONG_LONG_INT, AC_TYPE_UNSIGNED_LONG_LONG_INT):
1677 These no longer check for preprocessor flaws.
1678 * lib/autoconf/types.m4 (_AC_TYPE_LONG_LONG_SNIPPET):
1679 Do not check for preprocessor flaws.
1681 2007-11-13 Jim Meyering <meyering@redhat.com>
1683 Adapt dependencies, now that a version change doesn't modify configure.ac
1684 * GNUmakefile: Remove "make clean" kludge.
1685 * lib/m4sugar/Makefile.am (version.m4): Depend on Makefile, not
1686 configure.ac.
1687 Don't redirect directly to target.
1688 Use $@, not literal "version.m4".
1690 2007-11-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1692 * doc/autoconf.texi (Making testsuite Scripts): Document
1693 ":;{" shorthand as in previous patch.
1695 2007-11-12 Paul Eggert <eggert@cs.ucla.edu>
1697 * doc/autoconf.texi (Limitations of Builtins): Document problem
1698 with { ... } a bit more clearly. Suggest ":;{" as a shorthand
1699 for the workaround.
1700 * lib/m4sugar/Makefile.am (version.m4): Detect 'echo' failure.
1701 Use ":;{" shorthand.
1702 * tests/Makefile.am ($(srcdir)/package.m4): Likewise.
1704 2007-11-12 Jim Meyering <meyering@redhat.com>
1706 Add more non-srcdir build support.
1707 * GNUmakefile (dummy): Split a long line.
1708 Add -v option to autoreconf invocation.
1710 Remove the autoreconf-provided INSTALL, so that we regenerate it.
1711 * GNUmakefile (dummy): Remove INSTALL.
1713 Remove racy commands to build scripts in bin/ and tests/.
1714 * man/Makefile.am (.x.1): Now that scripts in bin/ and tests/
1715 are guaranteed to be built, remove the rules that tried to build
1716 them. Before, with a parallel build, these rules could lead to
1717 two processes writing tests/wrapper.in concurrently.
1719 Build in man/ only *after* building in bin/ and tests/.
1720 * Makefile.am (SUBDIRS): The man-page-creation process runs $(MAKE)
1721 in both bin/ and tests/.
1723 Accommodate non-srcdir build-from-checkout.
1724 * build-aux/git-version-gen: Require an additional parameter: $srcdir.
1725 Use git's --git-dir=$srcdir/.git option.
1726 Add quotes, in case tarball_version_file contains shell meta-characters.
1727 * GNUmakefile (_curr-ver): Pass $(srcdir) to git-version-gen.
1728 * configure.ac: Pass "." to git-version-gen.
1730 Avoid spurious test failures due to version skew.
1731 * GNUmakefile (dummy): Run $(MAKE) clean after autoreconf -i.
1733 2007-11-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1735 Avoid warnings about conftest.dSYM directories on Mac OS X Leopard.
1736 * lib/autoconf/general.m4 (_AC_LINK_IFELSE, _AC_RUN_IFELSE):
1737 Remove conftest.dSYM directory.
1738 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT)
1739 (_AC_LANG_PROGRAM_C_, _AC_FC_MAIN, __AC_FC_NAME_MANGLING):
1740 Remove `conftest.*' recursively.
1741 * lib/autoconf/lang.m4 (AC_LINK_IFELSE): Likewise.
1742 * lib/autoconf/specific.m4 (_AC_SYS_LARGEFILE_MACRO_VALUE):
1743 Likewise.
1744 (_AC_COMPILER_OBJEXT_REJECT): Reject *.dSYM.
1745 * THANKS: Update.

1755 Document that $((expression)) is not portable.
1756 * doc/autoconf.texi (Shell Substitutions): Here.
1758 2007-11-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1760 Ignore configure --help* errors due to LINENO-impaired shells.
1761 * tests/torture.at (Configuring subdirectories, Deep Package):
1762 In the --help* tests in read-only trees, make `.' temporarily
1763 writable again for the `stderr' file, and ignore errors due to
1764 the attempt to write configure.lineno.
1765 Report by Patrick Welche.
1767 2007-11-10 Jim Meyering <meyering@redhat.com>
1769 Generate package.m4 in build-dir, not srcdir.
1770 * tests/Makefile.am (package.m4): Adjust target.
1771 Don't redirect directly to $@.
1772 (CLEANFILES): Add package.m4.
1773 ($(TESTSUITE)): Depend on just-built package.m4, not the one
1774 in $(srcdir).
1775 When running $(AUTOTEST), search "." before searching $(srcdir).
1777 Avoid a race condition that would make parallel "distclean" fail.
1778 * tests/Makefile.am (distclean-generic): Replace the default,
1779 automake-provided rule with an identical one, but with an additional
1780 dependency on distclean-local. Simply adding the dependency would
1781 cause automake not to emit the rule at all.
1782 * BUGS: Building with -jN works, now.
1784 Distribute git-version-gen.
1785 * Makefile.am (EXTRA_DIST): Add build-aux/git-version-gen,
1786 since GNUmakefile is distributed, and requires it for dist* rules.
1788 Remove two more generated files from version control.
1789 * INSTALL: Remove generated file.
1790 * lib/autoscan/autoscan.list: Remove generated file.
1792 2007-11-09 Paul Eggert <eggert@cs.ucla.edu>
1794 * GNUmakefile (PATH): Remove stray apostrophes; they become
1795 part of PATH, which isn't wanted here.
1797 2007-11-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1799 New config files output variable `top_build_prefix'.
1800 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Substitute
1801 `top_build_prefix'.
1802 * doc/autoconf.texi (Preset Output Variables): Document it.
1803 * NEWS: Update.
1804 Report by Bob Friesenhahn.
1806 Avoid expr for arithmetic evaluation if the shell accepts $((...)).
1807 * lib/autotest/general.m4 (AT_INIT) <at_func_arith>: New
1808 function, to parametrize arithmetic with expr vs. the shell.
1809 Use it where possible.
1810 Suggestion by Benoit Sigoure.
1812 2007-11-03 Benoit Sigoure <tsuna@lrde.epita.fr>
1814 Adjust the documentation of autotest WRT atlocal.
1815 * doc/autoconf.texi (Making testsuite Scripts): It is not necessary,
1816 when using Automake, to write a rule to produce atlocal, since it's
1817 an AC_CONFIG_FILES. Mention that atlocal.in needs to be
1818 distributed, not atconfig.in.
1820 2007-11-04 Eric Blake <ebb9@byu.net>
1822 Update list information.
1823 * README: Mention new autoconf-commit list.
1824 * doc/autoconf.texi (Introduction): Mention autoconf-commit list.
1826 2007-11-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

1830 * lib/m4sugar/Makefile.am (version.m4): Another bash bug workaround.
1832 * build-aux/.gitignore: Ignore mkinstalldirs.
1834 * doc/autoconf.texi (autoreconf Invocation): Fix an underfull line.
1836 2007-11-03 Jim Meyering <meyering@redhat.com>
1838 s/-/./ in snapshot version string: 2.61a-256-8b556 -> 2.61a.256-8b556
1839 * build-aux/git-version-gen: This syncs from coreutils.
1841 Adjust the build procedure so "make check" works reliably.
1842 * README-hacking: Include an extra step between "make" and
1843 "make check" to ensure that the latter passes.
1845 Use just-built tools, when possible.
1846 * GNUmakefile (PATH): Set and export here, ...
1847 (dummy): ... rather than here.
1849 2007-11-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1850 and Andreas Schwab <schwab@suse.de>

1853 exit status bug.
1855 2007-11-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1857 * configure.ac (AC_PREREQ): Require version 2.60, for
1858 AC_PROG_SED, AC_PROG_GREP.
1860 2007-11-02 Benoit Sigoure <tsuna@lrde.epita.fr>

1868 workaround.
1870 2007-11-03 Eric Blake <ebb9@byu.net>
1872 Support m4 1.4.5 in testsuite.
1873 * tests/torture.at (Define a newline): Exclude line numbers in

1875 Reported by Ralf Wildenhues.
1877 2007-11-03 Jim Meyering <meyering@redhat.com>
1879 Remove automake-provided files from version control.

1890 * lib/m4sugar/m4sugar.m4 (_m4_version_unletter): Also treat - as a
1891 component separator.
1892 * doc/autoconf.texi (Number processing Macros)
1893 <m4_version_compare>: Document this change.
1894 * tests/m4sugar.at (m4@&t@_version_compare): Test it.
1896 2007-10-30 Bruno Haible <bruno@clisp.org>
1898 * lib/autoconf/types.m4 (_AC_TYPE_LONG_LONG_SNIPPET): New macro,
1899 extracted from AC_TYPE_LONG_LONG_INT and AC_TYPE_UNSIGNED_LONG_LONG_INT.
1900 (AC_TYPE_LONG_LONG_INT, AC_TYPE_UNSIGNED_LONG_LONG_INT): Use it.
1901 Fixes problem with Sun C 5.[0-8] in 32-bit mode, reported in
1902 <http://lists.gnu.org/archive/html/autoconf-patches/2007-10/msg00210.html>
1903 Suggested by Paul Eggert.
1905 2007-10-28 Jim Meyering <meyering@redhat.com>
1907 * README-hacking: Autoconf, Automake, and Perl are required to build.
1908 List Gzip and Tar separately. Suggested by Ralf Wildenhues.
1910 2007-10-28 Jim Meyering <meyering@redhat.com>
1912 README-hacking: Recommend running autoreconf -vi.
1913 * GNUmakefile (dummy): Use autoreconf -i, with appropriate PATH,
1914 so that we use just-built tools when they're available.
1915 Suggestions from Ralf Wildenhues.
1917 2007-10-28 Jim Meyering <meyering@redhat.com>
1919 Make inter-release --version output more useful.
1921 Now, each unofficial build has a version "number" like 2.61a-19-58dd,
1922 which indicates that it is built using the 19th change set
1923 (in _some_ repository) following the "v2.61a" tag, and that 58dd
1924 is a prefix of the commit SHA1.
1925 * build-aux/git-version-gen: New file.
1926 * configure.ac: Run it to set the version.
1927 (AM_INIT_AUTOMAKE): Don't check NEWS here.
1928 * Makefile.am (dist-hook): Arrange so that .version appears only
1929 in distribution tarballs, never in a checked-out repository.
1930 * .gitignore: Add .version here, too. Just in case.
1931 * tests/Makefile.am ($(srcdir)/package.m4): Depend on Makefile,
1932 not configure.ac, now that the version number changes automatically.
1934 Ensure that $(VERSION) is up to date for dist-related targets.
1935 * GNUmakefile: Arrange to rerun autoconf, if the version reported by
1936 git-version-gen doesn't match $(VERSION), but only for dist targets.
1938 2007-10-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1940 Fix `Deep Package' failure with a configure script early in PATH
1941 * tests/torture.at (Deep Package): Add `.' early in PATH.
1942 Report by Jim Meyering.
1944 2007-10-27 Jim Meyering <meyering@redhat.com>
1946 Remove all generated files from version control.

3192 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't look

3233 Document the restrictions on AC_CHECK_ALIGNOF's type argument.
3234 * lib/autoconf/types.m4 (_AC_CHECK_TYPE_NEW):
3235 For C, just try sizeof (TYPE) and sizeof ((TYPE)); if the former
3236 works but the latter doesn't, then it's a valid type.
3237 This lets people use function types and so forth.
3238 For C++ there doesn't seem to be a simple solution, so leave it alone.
3239 (AC_CHECK_SIZEOF): Allow argument to be a variable.
3240 (AC_CHECK_SIZEOF, AC_CHECK_ALIGNOF): Don't bother to invoke
3241 AC_CHECK_TYPE; that wasn't documented or necessary.

3363 carriage return.
3364 * doc/autoconf.texi (Limitations of Usual Tools): Document problem
3365 with traditional Awk and begin.
3366 * tests/torture.at (Limitations of Builtins): Document the problem
3367 with Bash 2.03 printf.
3368 (Substitute and define special characters):
3369 Remove trailing white space. Work around a bug in Solaris 8 /bin/bash.
3371 2007-02-06 Ralf Menzel <menzel@ls6.cs.uni-dortmund.de> (tiny change)
3373 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Redirect
3374 input from /dev/null in awk test, so even Solaris /usr/bin/awk
3375 will not wait for input with a script containing only a BEGIN
3376 rule.
3378 2007-02-03 Paul Eggert <eggert@cs.ucla.edu>
3380 * doc/autoconf.texi (Introduction, Why GNU M4): Clarify M4 version
3381 requirements.
3382 * README: Likewise.
3384 2007-02-02 Eric Blake <ebb9@byu.net>
3386 * NEWS: Update copyright.
3388 * m4/m4.m4 (AC_PROG_GNU_M4): Reject M4 1.4 through 1.4.4 as
3389 broken.
3390 * configure.ac: Update error message.
3391 * NEWS: Note that M4 1.4.5 or later is now a hard dependency.

3396 2007-01-31 Eric Blake <ebb9@byu.net>
3398 * THANKS (people): Update.
3400 2007-01-28 Paul Eggert <eggert@cs.ucla.edu>
3402 * doc/autoconf.texi (Shellology): pdksh 5.2.14 is still the
3403 latest version.
3404 (Shell Substitutions): Note problems with @{var:=value} etc.
3405 Add a new section for problems with @{#var} etc. Problem noted
3406 by Ralf Wildenhues. See:

3409 2007-01-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3411 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Also
3412 AC_SUBST([MKDIR_P]), so that Automake < 1.10 will pick up its
3413 trace, if a package uses AC_PROG_MKDIR_P explicitly. The actual
3414 substitution will still be done by the special code.
3415 Report by Jim Meyering.
3417 * doc/autoconf.texi (File System Conventions): Mention that
3418 $PATH_SEPARATOR is for the build system only.
3419 Report by Keith Marshall.
3421 2007-01-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

3424 all non-NUL characters are ok in substituted values.
3425 * lib/autoconf/status.m4 (_AC_SED_CMD_LIMIT): Fix comment typo.
3426 (_AC_OUTPUT_FILES_PREPARE): Test and use backslash escaping of
3427 carriage return for $AWK, needed for BSD awk.
3428 * tests/torture.at (Substitute and define special characters):
3429 Test all 8 bit non-NUL characters.
3430 Report against Automake by Patrick Welche.
3432 2007-01-15 Stepan Kasal <kasal@ucw.cz>
3434 * doc/autoconf.texi: Direntry for "autoconf Invocation" renamed.
3436 2007-01-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3438 * lib/autoconf/programs.m4 (AC_PROG_SED): When closing a pipe
3439 early on the reader side, drop stderr of the input to avoid
3440 `broken pipe' error output; this may happen even with shell
3441 builtin `echo' of some bash versions. Reports by Ian Macdonald
3442 <iamacdo@telkomsa.net> and Sam Sexton <Sam.Sexton@reuters.com>.
3444 2007-01-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3446 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Use newlines to
3447 separate items of `ac_user_opts', to avoid long lines.
3448 (_AC_INIT_PARSE_ENABLE2, _AC_ENABLE_IF_ACTION): Adjust.
3450 2007-01-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3452 * doc/autoconf.texi: Fix some typos.
3454 2007-01-05 Paul Eggert <eggert@cs.ucla.edu>
3456 Fix some wording problems noted by Paolo Bonzini in:
3457 http://lists.gnu.org/archive/html/autoconf-patches/2007-01/msg00077.html
3458 * doc/autoconf.texi (Signed Overflow Examples): Give more
3459 discussion about the allow_superuser_privileges example,
3460 and change it a bit to make things clearer.
3461 (Optimization and Wraparound): Clarify whether the compiler
3462 will generate an infinite loop for the example derived from
3463 Autoconf's mktime test.
3464 (Signed Overflow Advice): Say that -ftrapv is meant for debugging.
3465 Also, clarify unsigned multiplication overflow.
3467 2007-01-04 Eric Blake <ebb9@byu.net>
3469 * bin/Makefile.am (RELEASE_YEAR): New macro.
3470 (edit): Use it to supply correct copyright year to scripts.
3471 * bin/autoconf.as (version): Use it.
3472 * bin/autoheader.in ($version): Likewise.
3473 * bin/autom4te.in ($version): Likewise.
3474 * bin/autoreconf.in ($version): Likewise.
3475 * bin/autoscan.in ($version): Likewise.
3476 * bin/autoupdate.in ($version): Likewise.
3477 * bin/ifnames.in ($version): Likewise.
3479 2007-01-02 Paul Eggert <eggert@cs.ucla.edu>
3481 * doc/autoconf.texi (Integer Overflow): Revised based on today's
3482 feedback. The most important changes document what happens when
3483 you convert an out-of-range value to a signed integer type, and
3484 say that (sum < a) != (b < 0) reliably detects overflow when sum =
3485 a + b.
3487 * doc/autoconf.texi (Integer Overflow): Greatly expand and
3488 rewrite, taking notions from the recent discussion on the gcc and
3489 autoconf mailing lists; please see
3490 http://lists.gnu.org/archive/html/autoconf-patches/2006-12/msg00091.html
3491 and follow the many links.
3492 (Integer Overflow Basics, Signed Overflow Examples):
3493 (Optimization and Wraparound, Signed Overflow Advice):
3494 (Signed Integer Division): New sections.
3496 2006-12-28 Steven G. Johnson <stevenj@alum.mit.edu>
3498 * lib/autoconf/general.m4 (AC_DEFINE_TRACE): Don't include
3499 preprocessor macro arguments in traced name.
3500 * doc/autoconf.texi (Defining symbols): Document longstanding
3501 support for AC_DEFINE-ing macros with arguments, and document
3502 behavior when the same variable has multiple AC_DEFINEs.
3503 * lib/autoconf/fortran.m4 (_AC_FC_WRAPPERS): Revert to the
3504 old implementation which AC_DEFINEs the FC_FUNC and FC_FUNC_
3505 macros directly, giving much shorter and simpler code.
3507 2006-12-28 Malcolm Purvis <malcolmp@xemacs.org> (trivial change)
3509 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Insert a
3510 space before "$ac_configure_args" to prevent a 'config.status
3511 --recheck' failure if ac_configure_args doesn't contain a leading
3512 space. This works around a problem with the XEmacs configure.ac,
3513 which uses the (undocumented) ac_configure_args variable
3514 inconsistently with Autoconf.
3516 2006-12-22 Paul Eggert <eggert@cs.ucla.edu>
3518 * lib/autoconf/functions.m4 (AC_FUNC_MKTIME):
3519 Include <limits.h>, and use its INT_MAX to rewrite the
3520 j loop so that it does not overflow 'int'. Problem reported by
3521 Ralf Wildenhues in
3522 <http://lists.gnu.org/archive/html/bug-gnulib/2006-12/msg00084.html>.
3523 Play it safe by shifting left by 1 rather than multiplying by 2,
3524 as GCC is less likely to optimize this away when the value
3525 is signed (when it assumes overflow leads to undefined behavior).
3526 Also, don't assume time_t uses two's complement.
3528 2006-12-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3530 * tests/torture.at (Substitute a 2000-byte string): Avoid using
3531 a 10kB long (multi-line) string literal, OpenServer 5.0.7 ksh
3532 dumps core on it. Report by Tim Rice.
3534 2006-12-18 Steven G. Johnson <stevenj@alum.mit.edu>
3536 * lib/autoconf/general.m4 (AC_ARG_ENABLE): Print help about
3537 --disable-option-checking to --help output even when
3538 AC_PRESERVE_HELP_ORDER is not used.
3539 (_AC_INIT_PARSE_ENABLE2): Print warnings using actual --enable or
3540 --with argument, rather than argument with [-.] replaced by
3541 underscores.
3542 * NEWS: Fix typo in previous change; the news was in the
3543 wrong section.
3545 2006-12-18 Paul Eggert <eggert@cs.ucla.edu>
3547 * NEWS: Warnings are now generated by default for unknown
3548 --enable-* and --with-* options.
3549 * doc/autoconf.texi (Option Checking): Renamed from
3550 (Configure Option Checking). Tighten up the wording a bit.
3551 (External Software, Package Options): Cross-reference to Option
3552 Checking, and use this to shorten our section.
3553 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Prefer test -n
3554 "$x" to test "x$foo" != x.
3555 * lib/autoconf/status.m4 (AC_OUTPUT): Likewise.
3556 Don't warn if $enable_option_checking is "no".
3557 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Initialize
3558 ac_unrecognized_opts to the empty string.
3559 Don't echo the unrecognized opts, as this might mishandle
3560 backslashes or leading -.
3561 (AC_PRESERVE_HELP_ORDER): Put the --disable-option-checking
3562 usage next to the other --disable-FEATURE options in the
3563 help string.
3565 2006-12-18 Steven G. Johnson <stevenj@alum.mit.edu>
3567 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS, _AC_INIT_PARSE_ARGS):
3568 (_AC_INIT_PARSE_ENABLE2, _AC_INIT_HELP, _AC_ENABLE_IF):
3569 Print warning for unrecognized --with and --enable options
3570 (AC_DISABLE_OPTION_CHECKING): New macro to disable warnings.
3571 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS, _AC_OUTPUT_SUBDIRS):
3572 Disable option checking when subdirs are configured.
3573 (AC_OUTPUT): If warnings are enabled, print warning about
3574 unrecognized --with and --enable options at the end of
3575 the configure output (as well as at the beginning).
3576 * doc/autoconf.texi (Option Checking): New node.
3577 Document new option warning functionality.
3579 2006-12-16 Eric Blake <ebb9@byu.net>
3581 * configure.ac (AC_INIT): Bump version, since 2.61a is released.
3582 * NEWS: Start news for current version.
3584 2006-12-15 Paul Eggert <eggert@cs.ucla.edu>
3586 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT):
3587 Define HAVE_GETMNTENT to 1, not to the empty string.
3588 Problem originally reported by Jochen Friedrich in
3589 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=403243>.
3591 This change prompted by a problem report by Andrey Simonenko in
3592 <http://lists.gnu.org/archive/html/bug-autoconf/2006-12/msg00026.html>.
3593 * doc/autoconf.texi (Defining Symbols): AC_DEFINE works for
3594 object-like macros only, in the traditional portable character
3595 set.
3596 * lib/autoconf/general.m4 (AC_DEFINE_TRACE_LITERAL):
3597 Warn about attempts to define things that are not identifiers.
3598 * lib/autoconf/fortran.m4 (_AC_FC_WRAPPERS): Rewrite to avoid
3599 awful hack that AC_DEFINEd macro names containing parentheses.
3601 2006-12-12 Paul Eggert <eggert@cs.ucla.edu>
3603 * doc/autoconf.texi: Undo some of the 2006-12-10 change. It was
3604 too drastic, even if Texinfo in theory requires it for info mode.
3606 (config.status Invocation): Renamed back from Recreating a
3607 Configuration).
3608 (Obsolete config.status Use): Renamed back from Obsolete Recreation.
3609 (Autoconf 2.13): Renamed back from 20th-century Autoconf 2.
3611 2006-12-11 Paul Eggert <eggert@cs.ucla.edu>
3613 * NEWS: Version 2.61a.
3615 2006-12-11 Paul Eggert <eggert@cs.ucla.edu>
3616 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3618 * NEWS: Document changes with echo and printf, and the lack
3619 of limits on the total size of multi-line values of substituted
3620 variables, and the AC_FUNC_FSEEKO fix.
3622 2006-12-10 Paul Eggert <eggert@cs.ucla.edu>
3624 * doc/autoconf.texi (Writing Autoconf Input): Renamed from
3625 Writing configure.ac.
3626 (Autoconf Input Layout): Renamed from configure.ac Layout.
3627 (Recreating a Configuration): Renamed from config.status Invocation.
3628 (Obsolete Recreation): Renamed from Obsolete config.status Use.
3629 (acconfig Header): Renamed from acconfig.h.
3630 (20th-century Autoconf 2): Renamed from Autoconf 2.13.
3631 (Writing Testsuites): Renamed from Writing testsuite.at.
3632 (Autom4te Cache): Renamed from autom4te.cache.
3634 * BUGS: Remove mention of VPATH problem, since it's now documented
3635 not to be a bug in the Autoconf build procedure itself, but rather
3636 a problem with the proprietary `make' programs.
3638 * doc/autoconf.texi (Build Directories): Add a cross reference
3639 to VPATH and Make.
3641 * build-aux/config.guess, build-aux/config.sub, build-aux/texinfo.tex:
3642 * doc/standards.texi: Sync from gnulib.
3644 * man/autoconf.1, man/autoheader.1, man/autom4te.1, man/autoreconf.1:
3645 * man/autoscan.1, man/autoupdate.1, man/config.guess.1:
3646 * man/config.sub.1, man/ifnames.1: Remove from CVS, since they're
3647 generated automatically.
3649 2006-12-06 Paul Eggert <eggert@cs.ucla.edu>
3651 * lib/autoconf/c.m4 (_AC_PROG_CC_C89): Also try -xc99=all, for Sun
3652 C 5.8 on Solaris 10. Using -xc99=all rather than -xc99 bypasses
3653 the buggy -xc99 option of Forte Developer 7 C on Solaris 9.
3655 2006-12-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3657 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Drop the
3658 `CEOF$ac_eof' special marker, the awk script cannot contain a
3659 line matching `^CEOF', so this is not needed any more.
3660 * tests/torture.at (Substitute a newline): Expose the `%!_!# '
3661 special marker in the test.
3663 2006-12-06 Stepan Kasal <kasal@ucw.cz>
3665 * tests/tools.at (autom4te preselections): Use `find -newer';
3666 remove one of the sleeps.
3668 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE): Make it
3669 more readable, using ...
3670 (_AC_INIT_PARSE_ENABLE2): ... this new helper macro.
3672 * doc/autoconf.texi (autoheader Invocation): Do not double-
3673 quote the parameter of `AH_BOTTOM' in the example.
3675 2006-12-05 Stepan Kasal <kasal@ucw.cz>
3677 * doc/autoconf.texi (Configuration Headers): Remove the
3678 example with multiple input files.
3679 (autoheader Invocation): Encourage `AH_BOTTOM', discouraging
3680 multiple input files.
3682 2006-12-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3684 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): When
3685 creating the awk substitution script, handle one input line at a
3686 time, so that the maximum length of a substituted (multi-line)
3687 value is not limited by the size of the sed pattern space.
3688 The trade-off is a slightly repetitive sed script.
3689 * doc/autoconf.texi (Limitations of Usual Tools): Branch labels
3690 can only have up to 7 characters, due to Solaris 10 /bin/sed.
3691 * tests/torture.at (Substitute a 2000-byte string): Increase the
3692 test with several long lines, they should not be caught by sed
3693 limits any more.
3695 * tests/tools.at (autom4te preselections): New test, to flag
3696 entries missing from autom4te.cfg.
3697 Report by David Byron <dbyron@hheld.com>.
3699 * tests/torture.at (Substitute a 2000-byte string): Actually use
3700 AC_PROG_AWK, so the last change works as intended.
3701 (Substitute and define special characters): Likewise.
3702 (Substitute a newline): Likewise.
3704 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Use `$AWK'
3705 instead of `awk' consistently.
3706 (_AC_OUTPUT_CONFIG_STATUS): Initialize $AWK.
3707 * tests/torture.at (Torturing config.status): Test both the
3708 result of AC_PROG_AWK and plain awk.
3709 (Substitute a 2000-byte string): Likewise.
3710 (Substitute and define special characters): Likewise.
3711 (Substitute a newline): Likewise.
3713 2006-12-04 Paul Eggert <eggert@cs.ucla.edu>
3715 * lib/autoconf/functions.m4 (AC_FUNC_FSEEKO): Check that fseeko
3716 can be assigned to a function pointer. Problem reported by
3717 Peter Palfrader in <http://bugs.debian.org/401377>. Based on
3718 part of a patch by Ralf Wildenhues in that same bug report.
3720 2006-12-01 Paul Eggert <eggert@cs.ucla.edu>
3722 * tests/mktests.sh (ac_exclude_list): Exclude AC_FUNC_SETVBUF_REVERSED.
3723 * tests/semantics.at (AC_FUNC_SETVBUF_REVERSED): New test.
3725 2006-12-01 Eric Blake <ebb9@byu.net>
3727 * lib/autoconf/c.m4 (AC_LANG_INT_SAVE): Avoid newline, to aid in
3728 cross-compiling from cygwin to mingw.
3729 Reported by Bob Rossi. This resurrects the 2000-11-30 patch to
3730 aclang.m4, which was mistakenly removed in the 2001-09-17 patch
3731 to lib/autoconf/c.m4.
3733 2006-12-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3735 * lib/m4sugar/m4sh.m4 (_AS_ECHO_PREPARE): Use a longer test
3736 string for more reliable failure. Wrap the entire test that
3737 causes the broken Solaris printf to dump core, in a subshell,
3738 so the segmentation fault message is reliably suppressed.
3739 Fix shell expansion errors by using /usr/ucb/echo always;
3740 avoid an error on systems without it by another subshell.
3741 Avoid m4 expansion of `$1'. Set the zeroth argument of the
3742 subshell-$as_echo to `as_echo', for better error message.
3744 2006-11-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3746 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): If `BASH_ARGV' or
3747 `BASH_SOURCE' contain a newline, set them to empty, as they may
3748 not be unset.
3750 2006-11-27 Paul Eggert <eggert@cs.ucla.edu>
3752 Turn AC_FUNC_SETVBUF_REVERSED into a noop. It's been obsolete for
3753 years and is too hard to maintain now. The last straw was
3754 reported by Jerker Baeck in
3755 <http://lists.gnu.org/archive/html/autoconf/2006-11/msg00102.html>.
3756 * NEWS: AC_FUNC_SETVBUF_REVERSED is now obsolete.
3757 * doc/autoconf.texi (Particular Functions): Move
3758 AC_FUNC_SETVBUF_REVERSED from here...
3759 (Obsolete Macros): ... to here. Say that it does nothing now.
3760 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
3761 Turn into (almost) a no-op.
3763 * lib/autoconf/c.m4 (AC_PROG_GCC_TRADITIONAL, AC_C_CONST):
3764 (AC_C_VOLATILE):
3765 Do not recommend via AN_FUNCTION, AN_IDENTIFIER, or AN_HEADER.
3766 These macros are obsolescent and new applications shouldn't need them.
3767 * lib/autoconf/functions.m4 (AC_FUNC_CLOSEDIR_VOID, AC_REPLACE_FNMATCH):
3768 (AC_FUNC_GETLOADAVG, AC_FUNC_GETPGRP, AC_FUNC_MEMCMP):
3769 (AC_FUNC_SELECT_ARGTYPES, AC_FUNC_SETPGRP, AC_FUNC_STAT, AC_FUNC_LSTAT):
3770 (AC_FUNC_STRFTIME, AC_FUNC_SETVBUF_REVERSED, AC_FUNC_UTIME_NULL):
3771 (AC_FUNC_VPRINTF): Likewise.
3772 * lib/autoconf/headers.m4 (AC_HEADER_DIRENT, AC_HEADER_STAT):
3773 (AC_HEADER_STDC, AC_HEADER_SYS_WAIT, AC_HEADER_TIME): Likewise.
3774 * lib/autoconf/types.m4 (AC_STRUCT_TM): Likewise.
3776 * doc/autoconf.texi (Setting Output Variables): Mention that
3777 @VAR1@VAR2 has unspecified behavior. Problem reported by
3778 Ralf Wildenhues.
3779 * NEWS: Mention this.
3781 * Makefile.am: Put only a single '#' into the copyright notice,
3782 so that it's also present in the output file. Standardize wording
3783 in makefile copyright notices to match GNU coding standards.
3784 * bin/Makefile.am: Likewise.
3785 * doc/Makefile.am: Likewise.
3786 * lib/Makefile.am: Likewise.
3787 * lib/freeze.mk: Likewise.
3788 * lib/autoconf/Makefile.am: Likewise.
3789 * lib/autoscan/Makefile.am: Likewise.
3790 * lib/autotest/Makefile.am: Likewise.
3791 * lib/m4sugar/Makefile.am: Likewise.
3792 * man/Makefile.am: Likewise.
3793 * tests/Makefile.am: Likewise.
3794 * lib/emacs/Makefile.am: Remove copyright notice; it's just a
3795 one-line file.
3797 2006-11-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3799 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Fix error
3800 in the sed script that mangles the awk script: delete up to the
3801 first exclamation mark only.
3802 * tests/torture.at (Substitute and define special characters):
3803 Test '!' too.
3805 2006-11-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3807 Rewrite config files generation: avoid quadratic growth in
3808 the number of substituted variables by using awk instead of sed
3809 for the bulk of the substitutions.
3810 * NEWS: Mention this.
3811 * doc/autoconf.texi (Setting Output Variables): `|#_!!_#|' is also
3812 forbidden in the output (and thus input) file.
3813 * lib/autoconf/status.m4 (_AC_AWK_LITERAL_LIMIT): New macro.
3814 (_AC_OUTPUT_FILES_PREPARE): Instead of several sed scripts,
3815 generate just one large awk script for substitutions,
3816 eliminating much of the earlier complexity, while adding some
3817 new complexity. Only expand the substitution templates at
3818 configure time, for smaller configure script size. If
3819 _AC_SUBST_FILES are used, test 'awk' for working getline support
3820 at config.status time. If absent, interpolate through the
3821 shell. The awk script was written with much help
3822 from Paolo Bonzini and Paul Eggert.
3823 (_AC_SED_CMD_NUM, _AC_SED_DELIM_NUM, _AC_SED_FRAG): Removed.
3824 (_AC_SED_FRAG_NUM): Likewise.
3825 (_AC_SUBST_CMDS): Renamed from...
3826 (_AC_SED_CMDS): ...this.
3827 (_AC_OUTPUT_FILE): Use _AC_SUBST_CMDS.
3828 * tests/torture.at (Substitute a 2000-byte string): Also
3829 substitute a line with 1000 words, and a variable with several
3830 long lines.
3831 (Substitute and define special characters): Test awk special
3832 characters, and put substitution input strings `@foo@' in the
3833 output, to test that no recursion happens; test several other
3834 combinations from Paolo Bonzini.
3836 2006-11-25 Paul Eggert <eggert@cs.ucla.edu>
3838 * lib/autotest/general.m4 (AT_INIT): Undo recent changes
3839 that replaced echo with AS_ECHO where this wasn't necessary.
3840 Problem reportd by Ralf Wildenhues.
3841 * lib/m4sugar/m4sh.m4 (_AS_ECHO_PREPARE): Port to Solaris 7,
3842 where "/usr/bin/printf '%s\n' S" dumps core if S is long.
3843 This is Sun bug 4206210. Problem reportd by Ralf Wildenhues.
3845 2006-11-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3847 * lib/freeze.mk (GREP): Removed, no need to initialize this.
3849 2006-11-21 Paul Eggert <eggert@cs.ucla.edu>
3851 * doc/autoconf.texi (Limitations of Usual Tools): Don't claim
3852 that traditional Awk lacks 3-arg "split". It has it.
3853 Mention that FS must be a single character, and a few other
3854 99-byte limits of traditional Awk.
3855 Mention that if (i in a) doesn't work with traditional Awk.
3857 2006-11-18 Paul Eggert <eggert@cs.ucla.edu>
3859 * tests/autotest.at (BSx641-newline in command):
3860 (BS-BS-newline in command, BSx640-newline in command):
3861 (Newline-CODE-BS-newline in command):
3862 (Single-quote-BS-newline in command):
3863 (Single-quote-newline-BS-newline in command):
3864 Use printf '%s\n' instead of echo, for portability to hosts
3865 where echo interprets backslashes. This will break on hosts
3866 that lack printf, but for now let's assume all such hosts
3867 are dead (if not, we should get reports of test failures).
3869 2006-11-17 Paul Eggert <eggert@cs.ucla.edu>
3871 'echo' has some portability problems, when given a first argument
3872 with a leading '-', or when given any argument containing '\'.
3873 Avoid using 'echo' in these cases.
3874 * bin/Makefile.am $(bin_SCRIPTS): Rewrite to avoid 'echo' entirely.
3875 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX, AC_PROG_OBJC): Likewise.

3897 (_AS_BASENAME_SED, _AS_DIRNAME_SED, AS_MKDIR_P, AS_TMPDIR, AS_UNAME):
3898 (AS_TR_SH, AS_TR_CPP, AS_VAR_GET): Likewise.
3899 * bin/autoconf.as: Redo verbose flag implementation, as the old
3900 scheme wouldn't work with AS_ECHO.
3901 * lib/autotest/general.m4 (AT_INIT): Likewise.
3902 * lib/autoconf/general.m4 (AC_MSG_RESULT, AC_MSG_RESULT_UNQUOTED):
3903 Don't use ECHO_T, since ECHO_N is now reliable.
3904 * lib/autotest/general.m4 (AT_INIT): Likewise.
3905 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Use sed "$script"
3906 rather than using a here-document to put the script into a file.
3907 (_AC_DO_ECHO): Hoist the eval out of the echo, so that we can
3908 use AS_ECHO.
3909 * lib/m4sugar/m4sh.m4 (AS_VAR_GET): Likewise.
3910 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Use
3911 AS_ECHO_N rather than ECHO_N and ECHO_C. This doesn't fix any
3912 bug, but we might as well stop using ECHO_N and ECHO_C internally.
3913 * lib/autotest/general.m4 (AT_SETUP): Likewise.
3914 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N): Likewise.
3915 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
3916 (_AC_OUTPUT_MAIN_LOOP): Rework echo so that it has just one
3917 operand, as AS_ECHO requires. Avoid double file name expansion.
3918 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Invoke _AS_ECHO_PREPARE.
3919 Don't set as_nl, since _AS_ECHO_PREPARE does that now.
3920 (_AS_PREPARE): Comment that _AS_ECHO_N_PREPARE is just for user code.
3921 (AS_ECHO, AS_ECHO_N, _AS_ECHO_PREPARE): New macros.
3922 * tests/c.at (AC_PROG_CPP without warnings, AC_PROG_CPP via CC):
3923 Double-quote strings that would otherwise contain M4 comments.
3924 * tests/m4sh.at (AS_ECHO and AS_ECHO_N): New test.
3926 * configure.ac (AC_INIT): Bump to 2.61a.
3927 * NEWS: Likewise.
3929 2006-11-17 Paul Eggert <eggert@cs.ucla.edu>

3933 * configure.ac (AC_INIT): Bump to 2.61.
3934 * NEWS: Likewise.
3936 * tests/autotest.at (Macro with backslash in a test title):
3937 Comment out for now, as this tests neither fails nor passes
3938 reliably. Problem reported by Ralf Wildenhues.
3940 2006-11-16 Paul Eggert <eggert@cs.ucla.edu>
3942 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE): Fix some typos
3943 in previous change, which caused test failures.
3945 2006-11-16 Stepan Kasal <kasal@ucw.cz>
3947 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Factor out
3948 code for --enable, --disable, --with, and --without to...
3949 (_AC_INIT_PARSE_ENABLE): ... a new macro.

4016 * tests/mktests.sh (ac_exclude_list): Exclude AC_PROG_CXX_C_O, for
4017 benefit of platforms like Solaris+GCC where it is common to have a
4018 non-working g++ installation.

4030 * lib/autoconf/types.m4 (AC_TYPE_LONG_LONG_INT): Set
4031 ac_cv_type_long_long_int to 'yes' instead of 'cross-compiling'.
4032 Imported from a similar patch to gnulib by Bruno Haible.
4034 2006-11-08 Paul Eggert <eggert@cs.ucla.edu>
4036 * NEWS: New macros AC_C_FLEXIBLE_ARRAY_MEMBER, AC_C_VARARRAYS.

4045 Matthew Woehlke.
4047 2006-10-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4049 * tests/torture.at (Configuring subdirectories): Do not skip
4050 Automake 1.10 nor future Automake 11.1 (sic).
4052 2006-10-26 Joel E. Denny <jdenny@ces.clemson.edu>
4053 and Stepan Kasal <kasal@ucw.cz>
4055 Handle special characters in test case titles correctly.
4056 * lib/autotest/general.m4 (AT_INIT): M4-quote and AS_ESCAPE AT_help_all
4057 properly.
4058 (AT_SETUP): M4-quote and AS_ESCAPE the title properly everywhere.
4059 * tests/autotest.at (AT_CHECK_AT_TITLE): Add EXPANDED-TITLE-TO-TEST
4060 argument. Extend to check titles printed by ./micro-suite and
4061 ./micro-suite -l and the title in micro-suite.log.
4062 (Backquote in a test title,
4063 Single-quote in a test title,
4064 Double-quote in a test title): Don't expect failure anymore.
4065 (Backslash in a test title): Put a non-whitespace character after the
4066 backslash so that Bourne shells might actually see it as an escape
4067 sequence.
4068 (Brackets in a test title,
4069 Pound in a test title,
4070 Comma in a test title,
4071 Quoted Macro in a test title,
4072 Macro in a test title,

4078 AT_SETUP call so that no M4 code is commented inadvertently somewhere.
4079 The visible effect was a stray [] in the testsuite output.
4081 2006-10-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4083 * doc/autoconf.texi (Limitations of Builtins): Do not invoke
4084 `trap ... 0' inside a function, for AIX sh.
4086 2006-10-26 Paul Eggert <eggert@cs.ucla.edu>
4088 * tests/base.at (AC_COMPUTE_INT): Test **0** rather than 1 / 0,
4089 since powerpc-apple-darwin8-gcc-4.0.1 (Apple Computer, Inc. build
4090 5363) simply issues a warning when dividing by zero at compile
4091 time. Problem reported by Elias Pipping.
4093 2006-10-26 Eric Blake <ebb9@byu.net>
4095 * THANKS: Update.
4096 * doc/autoconf.texi (Evaluation Macros): Improve the example to
4097 show effect on macros that expand with commas.
4098 Reported by Joel E. Denny.
4100 * tests/m4sugar.at (m4_warn, m4_require: circular dependencies):
4101 Also work with M4 1.4.8.

4111 `--force' always rewrites the output file.
4113 2006-10-24 Paul Eggert <eggert@cs.ucla.edu>
4115 * doc/autoconf.texi (Limitations of Usual Tools): Document that rm

4125 If FUNCTION-BODY is nonempty, use AC_LINK_IFELSE rather than
4126 AC_COMPILE_IFELSE, to work around problem with OSF/1 4.0F fseeko
4127 reported by Nelson H. F. Beebe for Coreutils 6.4.
4129 * tests/tools.at (autoconf --trace: user macros): Remove test
4130 for tracing multiline macros, since m4 1.4.7a uses a different
4131 way to number lines. Problem reported by Ralf Wildenhues.
4133 2006-10-24 Stepan Kasal <kasal@ucw.cz>
4135 * bin/autom4te.in (handle_m4): Do not redirect stdin to
4136 /dev/null since the heuristics for interactive behaviour was
4137 fixed in CVS m4.
4139 * bin/autom4te.in: With --force, always refresh the output
4140 file. Problem reported by Greg Schafer <gschafer@zip.com.au>.
4142 * bin/autoconf.as: Fix the verbose message at the end.
4144 2006-10-23 Paul Eggert <eggert@cs.ucla.edu>

4161 * lib/autoconf/types.m4: All uses of AC_CACHE_CHECK_INT changed.
4162 * tests/base.at (AC_COMPUTE_INT): Test this, not AC_CACHE_CHECK_INT.
4164 2006-10-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4166 * doc/autoconf.texi (Limitations of Usual Tools): Fix two typos.
4168 2006-10-19 Eric Blake <ebb9@byu.net>

4192 * lib/m4sugar/m4sh.m4 (AS_LITERAL_IF): Expand $1 before
4193 looking for special shell characters.
4194 * lib/autoconf/functions.m4 (AC_CHECK_FUNC): Do not expand the
4195 macro defined by AS_VAR_PUSHDEF before passing it as a
4196 parameter.

4207 2006-10-14 Paul Eggert <eggert@cs.ucla.edu>
4209 (Imported from Automake.)
4210 * build-aux/install-sh (posix_mkdir): Reject FreeBSD 6.1 mkdir -p -m,
4211 which incorrectly sets the mode of an existing destination
4212 directory. In some cases the unpatched install-sh could do the
4213 equivalent of "chmod 777 /" or "chmod 0 /" on a buggy FreeBSD
4214 system. We hope this is rare in practice, but it's clearly worth
4215 fixing. Problem reported by Alex Unleashed in
4216 <http://lists.gnu.org/archive/html/bug-autoconf/2006-10/msg00012.html>.
4217 Also, don't bother to check for -m bugs unless we're using -m;
4218 suggested by Stepan Kasal.

4233 Import this change from Config:
4235 2006-09-20 Ben Elliston <bje@gnu.org>

4238 Import this change from Gnulib:
4240 2006-09-16 Karl Berry <karl@gnu.org>

4249 (\codequoteleft): new def, to look for @set codequotebacktick.
4250 (\lquoteexpand, \quoteexpand): new defs.
4251 (\lquoteChar, \rquoteChar, \dashChar, \underChar: new \chardef's.
4252 (\code): must use new \...Char values, since now ` is active.

4262 * doc/autoconf.texi (Autoheader Macros): Fix syntax error.
4264 2006-10-13 Stepan Kasal <kasal@ucw.cz>
4266 * doc/autoconf.texi (Autoheader Macros): Warn that the text
4267 added to the template can get mangled.
4269 2006-10-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4271 * lib/autoconf/functions.m4 (AC_FUNC_OBSTACK): In the test,
4272 include the default headers, and redefine obstack_chunk_alloc
4273 and obstack_chunk_free. Fixes false failure with glibc.
4275 2006-10-12 Paul Eggert <eggert@cs.ucla.edu>
4277 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Set as_executable_p,
4278 for backward compatibility with Libtool 1.5.22. Problem reported
4279 by Ralf Wildenhues.
4281 2006-10-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4283 * lib/autoconf/c.m4 (AC_PROG_GCC_TRADITIONAL): Require
4284 AC_PROG_CC.

4287 2006-10-11 Paul Eggert <eggert@cs.ucla.edu>
4289 * NEWS: AC_USE_SYSTEM_EXTENSIONS now defines _TANDEM_SOURCE for
4290 the NonStop platform.
4291 * doc/autoconf.texi (Posix Variants): Likewise.
4292 * lib/autoconf/specific.m4 (AC_USE_SYSTEM_EXTENSIONS): Likewise.
4294 * lib/m4sugar/m4sh.m4 (AS_TEST_X): New macro.
4295 (AS_EXECUTABLE_P): Use as_test_x rather than as_executable_p.
4296 (_AS_TEST_PREPARE): Set as_test_x rather than as_executable_p.
4297 Use a better substitute, by inspecting the output of "ls"
4298 rather than just using ":".
4299 * lib/autoconf/general.m4 (_AC_LINK_IFELSE): Use AS_TEST_X
4300 rather than AS_EXECUTABLE_P, since we needn't worry about
4301 non-regular files here.
4303 * NEWS: Autoconf-generated shell scripts no longer export BIN_SH,
4304 due to configuration hassles with this. See Tonya Underwood's report
4305 <http://lists.gnu.org/archive/html/bug-autoconf/2006-10/msg00003.html>.
4306 * doc/autoconf.texi (Special Shell Variables): Likewise.
4308 2006-10-11 Paul Eggert <eggert@cs.ucla.edu>
4309 Stepan Kasal <kasal@ucw.cz>
4311 * lib/m4sugar/m4sh.m4 (AS_BOURNE_COMPATIBLE): Don't set BIN_SH.
4312 (_AS_DETECT_BETTER_SHELL): Don't look in /usr/bin/posix.
4314 2006-10-11 Stepan Kasal <kasal@ucw.cz>
4316 * lib/m4sugar/m4sh.m4 (AS_BOURNE_COMPATIBLE): Move the
4317 initialization which is not inherited through the environment
4318 (_AS_BOURNE_COMPATIBLE): ... to this new macro.
4319 (_AS_RUN): Call _AS_BOURNE_COMPATIBLE, not AS_BOURNE_COMPATIBLE.
4321 2006-10-09 Paul Eggert <eggert@cs.ucla.edu>
4323 * doc/autoconf.texi (Limitations of Usual Tools): Describe
4324 problems with mkdir -p -m.
4326 2006-10-06 Paul Eggert <eggert@cs.ucla.edu>
4328 * lib/autoconf/c.m4 (_AC_PROG_PREPROC_WORKS_IFELSE): Remove
4329 comment about ac_cpp_err; it was incorrect, and anyway
4330 ac_cpp_err is being removed below.
4331 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE): Don't
4332 set ac_cpp_err to 'yesyes' if preproc_warn_flag and werror_flag
4333 are both 'yes'. In fact, don't bother setting ac_cpp_err at all;
4334 nobody uses it.
4335 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't log our funky tests
4336 with werror_flag and conftest.err and so forth. This is more
4337 compatible with how _AC_PROG_PREPROC_WORKS_IFELSE behaves,
4338 and anyway the user shouldn't normally want to see this gorp logged.
4339 Problem reported by Ralf Wildenhues.
4340 * lib/autoconf/lang.m4 (AC_LANG_WERROR): werror_flag's default is
4341 empty, not 'no', since the rest of the code uses 'test -z'.
4343 2006-10-04 Paul Eggert <eggert@cs.ucla.edu>
4345 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE):
4346 Use a single call to AC_DO_TOKENS rather than multiple, for
4347 efficiency.
4348 (_AC_LINK_IFELSE): Test that resulting file is executable.
4349 Problem reported by mwoehlke in
4350 <http://lists.gnu.org/archive/html/bug-coreutils/2006-10/msg00048.html>.
4352 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Use "test -x /" rather
4353 than creating a file to use with test -x; this is much faster.
4355 2006-10-02 Bruno Haible <bruno@clisp.org>
4357 * lib/autom4te.in (Automake-preselections): Add
4358 AM_GNU_GETTEXT_INTL_SUBDIR, for automake 1.10.
4360 2006-09-27 Stepan Kasal <kasal@ucw.cz>
4362 * doc/autoconf.texi (Writing testsuite.at): Fix a typo: for
4363 standard error, `experr' should be used, not `expout'.
4365 2006-09-26 Paul Eggert <eggert@cs.ucla.edu>
4367 * lib/autoconf/functions.m4 (AC_FUNC_FSEEKO): Don't compile the
4368 fseeko testing program twice; just use the earlier result.
4369 * lib/autoconf/specific.m4 (_AC_SYS_LARGEFILE_MACRO_VALUE):
4370 Set cache var to 'unknown' (not 'no') if leaving the macro unset
4371 still doesn't let the program compile.
4372 (AC_SYS_LARGEFILE): Test for _LARGE_FILES only if earlier tests
4373 failed.
4375 * lib/autoconf/functions.m4: Fix problems reported by Ralf Wildenhues.
4376 (AC_FUNC_ERROR_AT_LINE): Don't bother to check for error.h. Just
4377 include it, without including anything else.
4378 (AC_FUNC_FSEEKO): Avoid gcc -Wall warnings about constant
4379 expressions.
4380 (AC_FUNC_STRNLEN): Require AC_USE_SYSTEM_EXTENSIONS.
4382 2006-09-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4384 * lib/autoconf/functions.m4 (AC_FUNC_ERROR_AT_LINE): Check for
4385 `error.h', and include it, for a `error_at_line' prototype.
4386 Use a nonempty format string in the link test.
4387 * lib/autoconf/functions.m4 (AC_FUNC_WAIT3): Include <sys/wait.h>,
4388 for a declaration of wait3.
4390 2006-09-26 Paul Eggert <eggert@cs.ucla.edu>
4392 * NEWS: AC_CHECK_DECL now also works with aggregate objects.
4393 * doc/autoconf.texi (Generic Declarations): Clarify that AC_CHECK_DECL
4394 can apply to constants too, and that it checks for macro defns.
4395 * lib/autoconf/general.m4 (AC_CHECK_DECL): Assume C89 or better,
4396 and simply cast the identifier to void. This handles structure
4397 values. Problem reported by Ralf Wildenhues.
4398 * tests/semantics.at (AC_CHECK_DECLS): Also check enums.
4400 2006-09-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4402 * tests/semantics.at (AC_CHECK_DECLS): Also check macros,
4403 structure, and function symbols.
4405 2006-09-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

4432 * lib/autoconf/fortran.m4 (AC_PROG_F77, AC_PROG_FC): Likewise.
4433 Report by Olly Betts.
4435 2006-09-19 Eric Blake <ebb9@byu.net>

4453 * bin/Makefile.am (edit): Substitute M4_DEBUGFILE.
4454 * bin/autom4te.in (handle_m4): Favor --debugfile over misnamed
4455 --error-output, to avoid warnings with M4 2.0.
4457 2006-09-19 Stepan Kasal <kasal@ucw.cz>
4459 * lib/autoconf/libs.m4 (AH_CHECK_LIB): Fix quoting, to be
4460 consistent with _AH_CHECK_FUNCS and _AH_CHECK_HEADERS.
4461 * lib/autoconf/headers.m4 (AH_CHECK_HEADERS_DIRENT): Likewise.
4463 2006-09-15 Stepan Kasal <kasal@ucw.cz>

4466 expansion of AC_CHECK_FUNCS.
4468 2006-09-14 Stepan Kasal <kasal@ucw.cz>
4470 * lib/autoconf/general.m4 (AC_CONFIG_MACRO_DIR): Remove a
4471 mistaken comment: the path has to be relative; do not use
4472 the path at runtime.
4474 2006-09-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4476 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Quote the

4480 for both changes.
4481 * doc/autoconf.texi (Setting Output Variables): Fix example to
4482 not show `--silent' being passed to a `configure' re-run.
4484 2006-09-12 Paul Eggert <eggert@cs.ucla.edu>
4486 * doc/autoconf.texi (Input): Clarify role of AC_CONFIG_MACRO_DIR.
4487 * lib/autoconf/general.m4 (AC_CONFIG_MACRO_DIR): Do not check
4488 for the existence of the directory at configure-time. That's
4489 too late, anyway. Problem reported by Stefan Seefeld.
4491 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Avoid bug in UnixWare
4492 7.1.4 /usr/bin/posix/sh described by Tim Rice in
4493 <http://lists.gnu.org/archive/html/bug-autoconf/2006-09/msg00017.html>.
4495 2006-09-11 Stepan Kasal <kasal@ucw.cz>
4497 * tests/local.at (AT_CHECK_M4): Fix this so that the testsuite
4498 works with GNU M4 1.4.3 again; make the normalized form
4499 match the current m4 message; fix the description.
4500 * test/tools.at (autom4te cache): Adapt to the change.
4502 2006-09-08 Paul Eggert <eggert@cs.ucla.edu>
4504 * lib/autoconf/functions.m4 (AC_FUNC_MKTIME): Add year_2050_test
4505 to catch glibc bug 2821
4506 <http://sourceware.org/bugzilla/show_bug.cgi?id=2821>.
4508 Merge from gnulib as follows: Use AC_CHECK_HEADERS_ONCE instead of
4509 AC_CHECK_HEADERS, and likewise for AC_CHECK_FUNCS_ONCE and
4510 AC_CHECK_FUNCS. Don't check for stdlib.h, since we now
4511 assume C89.

4529 by Dries Kimpe.
4531 2006-09-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4533 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Prefer xlf90/xlf95 over
4534 f90/f95 because the latter drivers of AIX Fortran 9.1 do not
4535 accept files with extension `.f'. For consistency, also prefer
4536 xlf over f77.
4537 * doc/autoconf.texi (Fortran Compiler): Remove mention of bug
4538 from last patch.

4559 except the first two arguments are reversed.
4560 * doc/autoconf.texi (Caching Results): New macro AC_CACHE_CHECK_INT.
4561 (Generic Compiler Characteristics): AC_COMPUTE_INT no longer
4562 caches nor outputs a diagnostic. Suggested by Bruno Haible.

4564 equivalent to the old AC_COMPUTE_INT.
4565 (AC_COMPUTE_INT): No longer caches or reports. New signature.

4572 * NEWS: AC_FUNC_FNMATCH, AC_FUNC_FNMATCH_GNU, AC_FUNC_GETLOADVG,
4573 and AC_REPLACE_FNMATCH are now obsolescent in Autoconf. New
4574 programs should use their Gnulib counterparts.
4575 * doc/autoconf.texi (Particular Functions): Likewise.

4577 obsolete macros with uses of non-obsolete macros.

4607 for the default, which the user can override.
4608 * lib/autoconf/programs.m4 (AC_PROG_LEX): Let _AC_PROG_LEX_YYTEXT_DECL
4609 deal with LEXLIB.
4610 (_AC_PROG_LEX_YYTEXT_DECL): Handle caching correctly; the old code
4611 didn't work if some values were cached but not others. Test for
4612 broken lex libraries like native ia64-hp-hpux11.22; see
4613 <http://sources.redhat.com/ml/binutils/2003-12/msg00337.html>, and
4614 work around the problem by preferring an empty LEXLIB to -lfl or
4615 -ll. Let the user set LEXLIB='' to indicate no library needed.
4617 * NEWS: Recommend M4 1.4.6 instead of 1.4.5.
4618 * README: Likewise.
4619 * doc/autoconf.texi (Introduction, Why GNU M4): Likewise.

4714 * lib/autoconf/c.m4 (_AC_PROG_CC_C99): Test varargs macros and
4715 64-bit preprocessor ints. Check for static initialization of
4716 long long. Remove unnecessary casts.
4718 2006-08-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4720 * doc/autoconf.texi (Particular Programs): Mention that
4721 @INSTALL@ and @MKDIR_P@ may vary for different output files.
4722 Reported by Alexandre Duret-Lutz.
4724 2006-08-24 Paul Eggert <eggert@cs.ucla.edu>
4726 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS): Also ignore
4727 -lgcc?* and -lSystem, for Darwin/MacOS X. Problem reported by
4728 Bill Northcott in
4729 <http://lists.gnu.org/archive/html/autoconf/2006-08/msg00083.html>.
4731 2006-08-22 Paul Eggert <eggert@cs.ucla.edu>
4733 * lib/autoconf/c.m4 (AC_C_CONST): Don't used shadowed vars, to
4734 pacify insanely picky compilers. Problem reported by Eric Blake.
4736 * doc/autoconf.texi (Posix Variants): INTERACTIVE Unix is no
4737 longer supported by Sun.
4739 2006-08-15 Paul Eggert <eggert@cs.ucla.edu>
4741 * NEWS: Autoconf now uses constructs like "#ifdef HAVE_STDLIB_H"
4742 rather than "#if HAVE_STDLIB_H", so that it now works with "gcc
4743 -Wundef -Werror". Problem reported by David Fang in
4744 <http://lists.gnu.org/archive/html/autoconf/2006-08/msg00045.html>.
4745 * doc/autoconf.texi (Header Templates, Default Includes):
4746 (Particular Functions, Generic Functions, Header Portability):
4747 (Particular Headers, Generic Headers, Generic Declarations, Guidelines):
4748 (Obsolete Macros, AC_FOO_IFELSE vs AC_TRY_FOO):
4749 (Present But Cannot Be Compiled, Preprocessor Symbol Index):
4750 Prefer #ifdef to #if.
4751 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Prefer #ifdef to #if.
4752 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA, _AC_FUNC_MALLOC_IF):
4753 (AC_FUNC_MKTIME, AC_FUNC_MMAP, _AC_FUNC_REALLOC_IF):
4754 (AC_FUNC_SELECT_ARGTYPES, AC_FUNC_SETVBUF_REVERSED, _AC_FUNC_VFORK):
4755 Likewise.
4756 * lib/autoconf/headers.m4 (_AC_INCLUDES_DEFAULT_REQUIREMENTS):

4758 * lib/autoconf/specific.m4 (AC_DECL_SYS_SYGLIST):
4759 (AC_SYS_RESTARTABLE_SYSCALLS): Likewise.
4760 * lib/autoconf/headers.m4 (AC_HEADER_STAT): Don't assume that
4761 S_ISDIR etc. are valid for use in #if; POSIX doesn't guarantee
4762 this.
4764 2006-08-14 Paul Eggert <eggert@cs.ucla.edu>
4766 * doc/autoconf.texi (Limitations of Usual Tools): Document sed
4767 problems with arg script text that doesn't end in newline, and
4768 with '-e a...'. Problems reported by Ralf Wildenhues.
4770 2006-08-12 Alexandre Julliard <julliard@winehq.org> (tiny change)
4772 * lib/autoconf/libs.m4 (AC_PATH_X_DIRECT): Replace another
4773 check for libXt by a check for libX11.
4775 2006-08-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4777 * doc/autoconf.texi (config.status Invocation): Adjust according
4778 to last change.
4780 2006-08-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4782 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): `config.status
4783 --help' should mention that `--version' outputs configuration
4784 settings. Report by Bruno Haible.
4786 2006-08-06 Paul Eggert <eggert@cs.ucla.edu>
4788 Fix test suite failures reported by Pierre in
4789 <http://lists.gnu.org/archive/html/bug-autoconf/2006-08/msg00005.html>.
4790 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't claim
4791 the compiler created a file "b.out" when it didn't create anything
4792 at all.
4793 * lib/autoconf/specific.m4 (AC_SYS_INTERPRETER):
4794 Discard stderr too, when invoking the test script.
4796 2006-08-05 Alexandre Julliard <julliard@winehq.org> (tiny change)
4798 * lib/autoconf/libs.m4 (AC_PATH_XTRA): Fixed a typo
4799 in the restoring of the werror flag.
4801 2006-07-24 Paul Eggert <eggert@cs.ucla.edu>
4803 * doc/autoconf.texi (Volatile Objects): Be even a little
4804 less skeptical about "volatile", after discussion with
4805 Bruno Haible on bug-gnulib.
4806 (Limitations of Usual Tools): Warn about sed stripping
4807 leading white space from text. From Bruno Haible.
4809 2006-07-20 Paul Eggert <eggert@cs.ucla.edu>
4811 * lib/autoconf/libs.m4 (AC_PATH_XTRA): Don't use -R if the
4812 compiler complains about it, even if things works after the
4813 complaint. Problem reported by Peter O'Gorman.
4815 * doc/autoconf.texi (Preset Output Variables): Document CFLAGS,
4816 CPPFLAGS, and LDFLAGS better. Problem reported by Bruno Haible.
4817 Similarly for CXXFLAGS, OBJCFLAGS, ERLCFLAGS.
4819 2006-07-17 Paul Eggert <eggert@cs.ucla.edu>
4821 * lib/autoconf/libs.m4 (AC_PATH_XTRA): Do the check for space
4822 after -R regardless of host. Patrick Welche reports that this
4823 fixes things on NetBSD 3.99.
4825 * NEWS: Recommend M4 1.4.5.
4826 * README: Likewise.
4827 * doc/autoconf.texi (Introduction, Why GNU M4): Likewise.
4828 * tests/tools.at (autom4te cache): Update wording of diagnostic
4829 to match M4 1.4.5.
4831 2006-07-07 Paul Eggert <eggert@cs.ucla.edu>
4833 * doc/autoconf.texi (C Compiler): Add a ref to Volatile Objects
4834 under AC_C_VOLATILE.
4835 (Volatile Objects): Be a little less skeptical about what
4836 "volatile" means. Derived from thoughts by Ben Pfaff in
4837 <http://lists.gnu.org/archive/html/bug-gnulib/2006-07/msg00092.html>.
4839 2006-07-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4841 * doc/autoconf.texi: Fix some typos.
4843 2006-07-07 Paul Eggert <eggert@cs.ucla.edu>
4845 * tests/torture.at (Configuring subdirectories): Set CONFIG_SITE
4846 more globally, since the 2006-06-30 patch didn't suffice. Problem
4847 reported by Keith Marshall. Also, don't bother with builddir2,
4848 since it shouldn't be needed any more.
4850 2006-07-07 Paolo Bonzini <bonzini@gnu.org>
4852 * doc/autoconf.texi (Generic compiler characteristics):
4853 Document AC_COMPUTE_INT. Fix wrong statements on Default
4854 Includes for AC_CHECK_SIZEOF and AC_CHECK_ALIGNOF.
4856 * lib/autoconf/general.m4 (AC_COMPUTE_INT): New.
4857 (_AC_COMPUTE_INT): Add obsoletion warnings.
4858 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF, AC_CHECK_ALIGNOF): Use
4859 AC_COMPUTE_INT.
4861 * NEWS: Document change.
4863 2006-07-05 Paul Eggert <eggert@cs.ucla.edu>
4865 * doc/autoconf.texi (Volatile Objects): New section.
4867 * NEWS: Document previous change.
4869 2006-07-02 Paul Eggert <eggert@cs.ucla.edu>
4871 * lib/autoconf/types.m4 (AC_TYPE_LONG_LONG_INT):
4872 Require that long long int be at least 64 bits wide. C99 requires
4873 this and enough programs depend on it so we should check for it.
4874 Bruno Haible reports in
4875 <http://lists.gnu.org/archive/html/bug-gnulib/2006-06/msg00286.html>
4876 that long long int is 32 bits wide with some nonstandard compilers.
4877 (AC_TYPE_UNSIGNED_LONG_LONG_INT): Likewise.
4879 2006-06-30 Paul Eggert <eggert@cs.ucla.edu>
4881 * tests/torture.at (Configuring subdirectories): Set CONFIG_SITE
4882 to a nonexistent file, so that we don't have to worry about
4883 a local site configuration that doesn't use /usr/local.
4884 Problem reported by Keith Marshall in
4885 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00133.html>.
4887 2006-06-28 Paul Eggert <eggert@cs.ucla.edu>
4889 * doc/autoconf.texi: Be more consistent about using @acronym with
4890 "HP" and "HP-UX". Remove mention of OSF; the old version wasn't
4891 quite right (it talked about "OSF/Tru64", even though the
4892 operating systems were called OSF/1, Digital UNIX, and Tru64 UNIX,
4893 and it even mentioned "OSF 4"!) and at this point there's little
4894 reason to talk about OSF any more, since it died in 1994.
4895 (Specific Compiler Characteristics): Simplify example of
4896 negative-size array.
4897 (File Descriptors): Reorder to make the text flow better.
4898 Remove joke about "appreciate the various levels"; I didn't get it.
4899 Add remark about HP-UX sh -x bug with stderr noted by Bob Proulx in
4900 <http://lists.gnu.org/archive/html/bug-coreutils/2006-06/msg00225.html>.
4901 (File Descriptors, Limitations of Usual Tools):
4902 Tone down the advice against renaming or removing open files.
4903 (Limitations of Usual Tools): Add a new section, on 'rm'.
4905 2006-06-26 Stepan Kasal <kasal@ucw.cz>
4907 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Use -lX11, not
4908 -lXt in LIBS, idea from Karsten Hopp; this was due since
4909 this change:
4911 2005-09-18 Paul Eggert <eggert@cs.ucla.edu>
4912 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Look for X11/Xlib.h
4913 and XrmInitialize rather than X11/Intrinsic.h and XtMalloc
4914 (which belong to Xt, not X itself). See Debian bug 327655.
4916 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4918 * configure.ac (AC_INIT): Bump to 2.60a.
4919 * NEWS: Update.
4921 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4923 Version 2.60.
4925 * configure.ac, NEWS: Update.
4927 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4929 * config/texinfo.tex: Sync from upstream.
4931 * bin/autom4te.in (handle_traces): Transform the `@S|@'
4932 quadrigraph correctly in traces.
4934 * NEWS, lib/Autom4te/C4che.pm, lib/autoconf/functions.m4:
4935 Fix typos.
4937 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Expand tests for
4938 datarootdir-related errors only if AC_DATAROOTDIR_CHECKED is
4939 not defined.
4940 * doc/autoconf.texi (Changed Directory Variables): New node,
4941 to document the whole `datarootdir' business a bit better.
4942 * NEWS: Update.
4943 * tests/torture.at (datarootdir workaround): Extend test.
4944 Prompted by report by Alexandre Julliard.
4946 2006-06-22 Paul Eggert <eggert@cs.ucla.edu>
4948 * lib/autoconf/c.m4 (_AC_PROG_CC_C89): Check for C89 incompatibility
4949 when using default mode of IBM C 6 for AIX. Problem and two-line
4950 fix reported by Larry Jones.
4952 2006-06-22 Alexandre Julliard <julliard@winehq.org>
4954 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Avoid warning
4955 about literal '${datarootdir}' if a definition is found in the
4956 output file.
4958 2006-06-20 Paul Eggert <eggert@cs.ucla.edu>
4960 * NEWS: Use "M4" rather than "m4" when appropriate.
4961 Problem reported by Eric Blake.
4962 * doc/autoconf.texi: Likewise.
4963 Use @acronym around BSD, GCC, and GNU when appropriate.
4964 (Why GNU M4): Renamed from "Why GNU m4".
4965 (Redefined M4 Macros): Mention that Posix
4966 m4wrap takes only 1 argument, but GNU M4 1.4.x takes more.
4967 (Buffer Overruns): Mention size_t and ptrdiff_t as alternatives
4968 to int.
4970 2006-06-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4972 * bin/autom4te.in (handle_output): Do not forbid the empty
4973 pattern.
4974 * tests/tools.at (autoconf: the empty token): New test.
4976 2006-06-20 Stepan Kasal <kasal@ucw.cz>
4978 * lib/m4sugar/m4sugar.m4 (m4_init): Merge the two m4_wrap
4979 calls, so that we do not care whether they are LIFO or FIFO;
4980 in the m4_wrap, do not check which diversion is the topmost
4981 one, just check that the stack is balanced at the end.
4982 * lib/m4sugar/m4sh.m4 (AS_INIT): We are going to change the
4983 base diversion forever--pop the previous diversion before
4984 opening the new one; consequently, remove the m4_wrap call.
4985 * lib/autotest/general.m4 (AT_INIT): Likewise.
4986 * tests/m4sugar.at: Do not use
4987 m4_wrap([m4_diversion_pop([..])]), for educational purposes.
4989 2006-06-19 Paul Eggert <eggert@cs.ucla.edu>
4990 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4992 * NEWS: Document that m4wrap/m4_wrap might not be LIFO.
4993 * doc/autoconf.texi (Redefined M4 Macros): Likewise.
4994 Rework example of m4wrap token-pasting trouble so that it doesn't
4995 care whether it's LIFO or FIFO.
4996 Fix some "contrary to"s that are awkward in English.
4998 2006-06-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5000 * lib/autoconf/types.m4 (_AC_TYPE_INT): Set `$ac_cv_c_int$1_t'
5001 to `yes' instead of `int$1_t' if the type is found, for more
5002 consistent configure output (where $1 is the number of bits).
5003 (_AC_TYPE_UINT): Likewise for `uint$1_t'.
5004 Suggested by Bruno Haible.
5006 * lib/autoconf/types.m4 (_AC_TYPE_UNSIGNED_INT): Solaris 2.5.1
5007 needs _UINT8_T and _UINT64_T defines as well, to avoid clashes
5008 with system headers. Report by Bruno Haible.
5010 2006-06-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5012 * config/config.guess, config/config.sub: Sync from upstream.
5014 * bin/Makefile.am (autoconf.in): Use `--melt' for autom4te,
5015 in order to avoid picking up an older installed frozen m4sh.m4f.
5016 Besides an outdated shell startup, this could have been created
5017 by an earlier M4 version with incompatible frozen file format.
5019 2006-06-16 Paul Eggert <eggert@cs.ucla.edu>
5021 * README: Recommend m4 1.4.4 instead of 1.4.3..
5022 * doc/autoconf.texi: Likewise.
5023 (Special Chars in Names): Say that $(.FOO) is portable, as
5024 suggested by Stepan Kasal.
5025 (Installation Directory Variables, Build Directories):
5026 (Automatic Remaking, Subdirectories, Fortran Compiler):
5027 (Making testsuite Scripts, Defining Directories):
5028 Quote variable usages better.
5029 (Making testsuite Scripts): Add clean-local rule to makefile
5030 snippet, by Eric Blake.
5031 (Installation Directory Variables): Fix table item font.
5032 Reword slightly to clarify. Generalize advice about
5033 not using special characters to include all file-related
5034 vars, not just VPATH.
5035 (Special Chars in Variables): Warn about special characters in
5036 $(srcdir) too.
5037 (Assignments): Clarify default-value example as suggested by
5038 Ralf Wildenhues in
5039 <http://lists.gnu.org/archive/html/autoconf-patches/2006-06/msg00072.html>.
5040 (Special Shell Variables): Note leading ./ or ../, as suggested
5041 by Eric Blake.
5042 (Limitations of Builtins): Under cd, warn about CDPATH.
5043 (The Make Macro MAKEFLAGS): Untabify. Problem reported by
5044 Ralf Wildenhues.
5046 2006-06-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5048 * doc/autoconf.texi (Configuration Actions): Remove duplicate
5049 `@var', for texi2html.
5050 (Systemology): Some more word wrapping, for DVI output.
5051 (autom4te Invocation): The short option for `--melt' is `-M',
5052 not `-m'.
5054 2006-06-15 Paul Eggert <eggert@cs.ucla.edu>
5056 * doc/autoconf.texi: More formatting and English tweaks,
5057 many suggested by Ralf Wildenhues.
5058 Reword to avoid "@code{...}'s" and the like, since it's ugly
5059 with Emacs info mode. discontents -> woes.
5060 Put a few "will"s back. time stamp -> timestamp.
5061 side-effect -> side effect.
5063 2006-06-14 Paul Eggert <eggert@cs.ucla.edu>
5065 * doc/autoconf.texi (Initializing configure, Shell Substitutions):
5066 Warn about $@ not persisting. Problem reported by Julien Danjou in
5067 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=372179>.
5068 (Special Chars in Names): Renamed from Leading _ in Macro Names.
5069 Mention other special chars, too.
5071 2006-06-14 Eric Blake <ebb9@byu.net>
5073 * doc/autoconf.texi (The Make Macro MAKEFLAGS): New node.
5075 2006-06-13 Paul Eggert <eggert@cs.ucla.edu>
5077 * doc/autoconf.texi: Some systematic minor improvements, as
5078 follows. Use "makefile" when talking about makefiles
5079 generally (which might be named "makefile" or "Makefile" or even
5080 "foo.mk"), "Makefile" when talking about a specific makefile
5081 called "Makefile". This unclutters the text from weird quotes
5082 (e.g., "`Makefile's" in info mode). Similarly, use "@var{foo}
5083 values" rather than "@var{foo}s" and similar constructs containing
5084 "}s". Use "Make rules" rather than "Makefile rules". Minor
5085 English-language improvements. Change the prefix "sub-" to "sub"
5086 and "re-" to "re".
5087 Put blank lines around examples more consistently.
5088 Avoid "rather" and "very" as intensifiers.
5089 Avoid "will" as an auxiliary.
5090 (Limitations of Make): Split this node into....
5091 (Portable Make, $< in Ordinary Make Rules, Failure in Make Rules):
5092 (Leading _ in Macro Names, Backslash-Newline-Newline):
5093 (Backslash-Newline Comments, Long Lines in Makefiles):
5094 (Macros and Submakes, The Make Macro SHELL, Comments in Make Rules):
5095 (obj/ and Make, make -k Status, VPATH and Make):
5096 (VPATH and Double-colon, $< in Explicit Rules):
5097 (Automatic Rule Rewriting, OSF/Tru64 Directory Magic):
5098 (Make Target Lookup, Single Suffix Rules, Timestamps and Make):
5099 New nodes, resulting from splitup of Limitations of Make.
5100 All cross-references changed. Raise the top node from
5101 a section to a chapter, and all subnodes accordingly.
5102 Redo the introductory wording to match the new organization.
5103 (Installation Directory Variables): Use an example that is
5104 closer to what Autoconf actually does. Mention that VPATH's
5105 value should not contain metacharacters or white space.
5106 (Fortran Compiler): Fix a VPATH bug in an example.
5107 (Leading _ in Macro Names): Mention that this problem is no longer
5108 of practical concern.
5109 (VPATH and Make): Reword the advice to make it clearer
5110 that Autoconf and Automake support VPATH in non-GNU make, but
5111 many packages have bugs in this area.
5112 ($< in Explicit Rules): Refer to Build Directories rather
5113 than using a (non-VPATH-safe) example.
5114 (Automatic Rule Rewriting): Mention the sort of disaster that
5115 can ensue with Solaris-style rule rewriting with VPATH.
5117 2006-06-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5119 * doc/install.texi (Compilers and Options): Weaken the
5120 suggestion to use GNU make for VPATH builds.
5122 * lib/autom4te.in (Automake-preselections): Add AM_PROG_CXX_C_O,
5123 AM_PROG_F77_C_O, AM_PROG_FC_C_O, AC_FC_SRCEXT, AC_FC_FREEFORM.
5125 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Fix M4 quotation
5126 in regular expression.
5128 2006-06-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5130 * doc/autoconf.texi (Installation Directory Variables):
5131 Drop extra @samp from `@table @samp' item.
5132 (Limitations of Usual Tools): Comment fix.
5133 Do not nest @samp just to point to other table items.
5134 (Writing testsuite.at) <AT_CHECK>: The second argument to
5135 `@dvar' is already @samp'ed.
5136 (Making testsuite Scripts) <AC_CONFIG_TESTDIR>: Likewise,
5137 do not use @var in the second argument.
5139 2006-06-07 Paul Eggert <eggert@cs.ucla.edu>
5141 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Look for
5142 $as_shell.exe too. Problem reported by Andreas Buening in
5143 <http://lists.gnu.org/archive/html/autoconf/2006-06/msg00038.html>.
5145 2006-06-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5147 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA): Work around
5148 `unused variable' compiler warning, for `-Wall -Werror'.

5152 2006-06-06 Paul Eggert <eggert@cs.ucla.edu>
5154 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Remove core file, in
5155 case the compiler dumps core. Problem reported for
5156 OpenServer 5.0.7 by Tim Rice in
5157 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00019.html>.
5158 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE):
5159 Likewise.
5161 2006-06-06 Tim Rice <tim@multitalents.net>.
5163 * lib/freeze.mk: Quiet check-forbidden-patterns so the string
5164 "ERROR" only shows up in "make check" output if there is an
5165 error.
5167 2006-06-06 Eric Blake <ebb9@byu.net>
5169 * tests/tools.at (automatically allowed tokens): Fix typo.
5171 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
5173 * NEWS: Don't blame non-GNU VPATH compatibility issues on Automake.
5175 * doc/autoconf.texi (Integer Overflow): Mention that INT_MIN % -1
5176 typically overflows on x86 CPUs, even though the C standard
5177 requires otherwise.
5179 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5181 * configure.ac (AC_INIT): Bump to 2.59e.
5182 * NEWS: Update.
5184 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5186 Version 2.59d.
5188 * config/texinfo.tex: Sync from upstream.
5190 * bin/autoreconf.in: Trace `LT_CONFIG_LTDL_DIR'; if it has been
5191 seen, invoke libtoolize with `--ltdl' argument.
5192 * lib/autom4te.in (Autoreconf-preselections): Adjust.
5193 * NEWS: Update.
5194 Suggested by Eric Blake.
5196 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
5198 * NEWS: Whoops! AC_FUNC_STRNLEN isn't obsolescent. Problem
5199 reported by Ralf Wildenhues.
5200 * doc/autoconf.texi (AC_FUNC_STRNLEN): Likewise.
5202 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5204 * THANKS: Update.
5206 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
5208 * doc/autoconf.texi: Modernize some of the references to Solaris.
5210 2006-06-05 Stepan Kasal <kasal@ucw.cz>
5212 * lib/m4sugar/m4sugar.m4 (m4_require): Modify the error
5213 message issued by AC_REQUIRE.
5214 * tests/m4sugar.at: Check m4_require's error message.
5215 * tests/base.at: Check AC_REQUIRE's error message.
5216 * tests/local.at (AT_CHECK_M4): New macro, almost identical
5217 to...
5218 (AT_CHECK_AUTOM4TE): ... which is now a thin wrapper around
5219 AT_CHECK_M4.
5220 (AT_CHECK_AUTOCONF): Use AT_CHECK_M4; no longer support
5221 `expout' as the last parameter.
5222 * tests/tools.at: Adapt to the above change.
5224 2006-06-04 Stepan Kasal <kasal@ucw.cz>
5226 * doc/autoconf.texi (Limitations of Usual Tools): Correct
5227 information about race-free implementations of mkdir.
5229 2006-06-04 Eric Blake <ebb9@byu.net>
5231 * bin/autoreconf.in (help): Document M4 environment variable.
5232 * bin/autoconf.as (Usage): Likewise.
5233 * bin/autom4te.in (help): Likewise.
5234 * doc/autoconf.texi (autom4te Invocation): Likewise.
5236 2006-06-04 Paul Eggert <eggert@cs.ucla.edu>
5238 * NEWS: GNU make now recommended for VPATH builds.
5239 Mention that some macros are now documented to be obsolescent.
5240 * doc/autoconf.texi:
5241 Prefer "current" to "modern" to describe
5242 currently-used (albeit perhaps old-fashioned) hosts.
5243 Mention which ancient features no longer need to be worried about.
5244 setgid -> set-group-ID
5245 setuid -> set-user-ID (these are the Posix terms)
5246 Fix some misuses of "only".
5247 (AC_C_BACKSLASH_A, AC_C_CONST, AC_C_PROTOTYPES):
5248 (AC_C_STRINGIZE, AC_C_VOLATILE, AC_FUNC_CLOSEDIR_VOID):
5249 (AC_FUNC_GETPGRP, AC_FUNC_LSTAT, AC_FUNC_MEMCMP):
5250 (AC_FUNC_SELECT_ARGTYPES, AC_FUNC_SETPGRP):
5251 (AC_FUNC_SETVBUF_REVERSED, AC_FUNC_STAT, AC_FUNC_STRFTIME):
5252 (AC_FUNC_STRNLEN, AC_FUNC_UTIME_NULL, AC_FUNC_VPRINTF):
5253 (AC_HEADER_DIRENT, AC_HEADER_STAT, AC_HEADER_STDC):
5254 (AC_HEADER_SYS_WAIT, AC_HEADER_TIME, AC_ISC_POSIX):
5255 (AC_PROG_GCC_TRADITIONAL, AC_STRUCT_TM):
5256 Mention that these macros are obsolescent.
5257 (Installation Directory Variables): shall -> should
5258 (File Descriptors): Mention that 0, 1, 2 might get reopened.
5259 Mention that it's now safe to use 3 and 4.
5260 (Limitations of Usual Tools): cp -r is now specified by Posix.
5261 Omit longwinded and obsolescent discussion of cp -f.
5262 Modernize discussion of expr, ls.
5263 (Limitations of Make): Modernize discussion of VPATH builds.
5264 Mention $? as a workaround in some cases.
5265 * doc/install.texi (Basic Installation):
5266 Mention "./configure; make; make install" first. Be more
5267 specific about why this file is generic. Remove unnecessary
5268 parens. Remove misleading "only". Remove obsolete advice
5269 about csh. Don't say "configure" takes awhile; say it
5270 might take a while. Suggest CFLAGS=-g rather than CFLAGS=-O2,
5271 and CC=c99 rather than CC=c89, as these are blessed by current
5272 Posix. Recommend GNU make if doing a VPATH build.
5274 2006-06-03 Paul Eggert <eggert@cs.ucla.edu>
5276 * doc/autoconf.texi: Use a consistent style "$ @kbd{...}" for
5277 examples involving shell prompts.
5279 2006-06-02 Stepan Kasal <kasal@ucw.cz>
5280 and Paul Eggert <eggert@cs.ucla.edu>
5282 * doc/autoconf.texi (Here-Documents): Add details about the
5283 pre-ksh93g bug. Reword slightly to make it clearer. Consistently
5284 use "here-documents" instead of "here documents".
5286 2006-06-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5288 * config/texinfo.tex, doc/standards.texi: Sync from upstream.
5290 2006-06-01 Paul Eggert <eggert@cs.ucla.edu>
5292 * doc/autoconf.texi (File System Conventions): Warn about ":"
5293 anywhere in directory names.
5295 2006-05-31 Paul Eggert <eggert@cs.ucla.edu>
5297 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be even more conservative
5298 about quoting the case statement, just in case.
5299 * doc/autoconf.texi (Here-Documents): Mention that the ksh bug
5300 was fixed in ksh93g; reported by Ralf Wildenhues.
5302 2006-05-31 Stepan Kasal <kasal@ucw.cz>
5304 * doc/autoconf.texi (System Services): Do not document
5305 overriding EXEEXT via ac_cv_exeext=ext.
5306 (Particular Programs) <AC_PROG_MKDIR_P>:
5307 Document that ${MKDIR_P} understands --.
5308 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Improve the
5309 comment.
5311 2006-05-31 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5313 * lib/m4sugar/m4sh.m4 (_AS_DIRNAME_PREPARE): Guard against test
5314 argument with leading hyphen. Problem reported by Paul Eggert.
5316 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
5318 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be more conservative
5319 about quoting ac_try: quote all of it, if any of it seems suspicious.
5320 This means we don't have to worry about ${ or sed any more.
5321 Also, double-quote the case statement, to work around misuses via
5322 underquoting as reported by Ralf Wildenhues in
5323 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00169.html>.
5324 (_AC_EVAL_STDERR): Revert, since evidently some packages rely on this
5325 undocumented and dangerous macro.
5326 Problem reported by Ralf Wildenhues in
5327 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00168.html>.
5329 2006-05-31 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5331 * lib/m4sugar/m4sh.m4 (_AS_DIRNAME_PREPARE): Check whether
5332 `dirname -- /' returns `/', for SunOS dirname scripts that escaped.
5333 Report by Sam Sirlin <sam@kalessin.jpl.nasa.gov>.
5335 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
5337 * lib/autoconf/general.m4: Revert AC_TRY_EVAL and AC_TRY_COMMAND,
5338 since evidently some packages rely on the old, broken behavior.
5339 Problem reported by Ralf Wildenhues in
5340 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00160.html>.
5341 (AC_TRY_EVAL, AC_TRY_COMMAND, _AC_EVAL): Go back to the
5342 pre-2006-05-26 definitions, but leave in the comments that
5343 these macros are dangerous and should not be used.
5344 (_AC_DO_ECHO): Renamed from _AC_EVAL_ECHO. All callers changed.
5345 (_AC_DO): Renamed from _AC_EVAL. All callers changed.
5346 (_AC_DO_STDERR): Renamed from _AC_EVAL_STDERR. All callers changed.
5347 (_AC_DO_VAR): Renamed from AC_TRY_EVAL.
5348 (_AC_DO_TOKENS): Renamed from AC_TRY_COMMAND.
5350 2006-05-29 Paul Eggert <eggert@cs.ucla.edu>
5352 * lib/autoconf/status.m4 (AC_OUTPUT_MAKE_DEFS): Rewrite to avoid
5353 the use of 'tr', since this is our only use of 'tr'.
5355 2006-05-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5356 and Paul Eggert <eggert@cs.ucla.edu>
5358 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE):
5359 Don't assume 'grep' works on long lines, since AIX grep doesn't.
5361 2005-05-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5363 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Do not use `grep' on
5364 the output file in the `${datarootdir}' test.
5366 2005-05-28 Stepan Kasal <kasal@ucw.cz>
5367 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5369 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If we have not seen
5370 mention of `datarootdir' in the input file(s), but literal
5371 `${datarootdir}' in the output file, and we haven't warned yet,
5372 then warn as well: the user may have (erroneously) used
5373 `AC_SUBST([mydatadir], [$datadir/my])' instead of the correct
5374 `AC_SUBST([mydatadir], ['${datadir}/my'])'.
5375 * tests/torture.at (datarootdir workaround): Extend this test.
5376 * NEWS: Update.
5378 2006-05-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5379 and Paul Eggert <eggert@cs.ucla.edu>
5381 * doc/autoconf.texi (autoheader Invocation): The first argument to
5382 `AC_DEFINE_UNQUOTED' need not be a literal. Mention the
5383 alternatives and clear up the language a bit.
5385 2006-05-27 Paul Eggert <eggert@cs.ucla.edu>
5387 * NEWS: Reword notice for AC_TRY_COMMAND, AC_TRY_EVAL,
5388 ac_config_guess, ac_config_sub, ac_configure.
5389 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
5390 Fix typo that prevented an unnecessary space from being removed.
5391 Problems reported by Ralf Wildenhues in:
5392 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00143.html
5394 2006-05-26 Paul Eggert <eggert@cs.ucla.edu>
5396 * doc/autoconf.texi (Particular Programs, Limitations of Usual Tools):
5397 Use better wording to talk about AC_PROG_MKDIR_P's thread-safety.
5398 Don't use the term "thread-safe" to talk about mkdir race
5399 conditions, since the problem is more a process than a thread
5400 issue. Problem reported by Stepan Kasal in:
5401 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00088.html
5402 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Use code that mimics
5403 the test for 'install' more closely. Look at MKDIR_P first.
5404 Look in the PATH, and at /opt/sfw/bin.
5405 Look for a 'gmkdir' program as well (Solaris 10 /opt/sfw/bin/gmkdir).
5406 Don't bother to try mkdir -p, since we already check mkdir --version;
5407 just look at the version number. (There's no easy way to check
5408 for race-free implementations.)
5409 * tests/tools.at (autoconf: subdirectories): Adjust to above
5410 changes, since MKDIR_P now might end in "/mkdir -p".
5412 * doc/autoconf.texi (autoheader Invocation): Mention that the
5413 first arg of AC_DEFINE_UNQUOTED must be a literal.
5414 Problem reported by Ben Pfaff in
5415 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00090.html>.
5417 * NEWS: Mention that AC_TRY_COMMAND and AC_TRY_EVAL may be removed.
5418 * doc/autoconf.texi (Special Chars in Variables): New section.
5419 (Preset Output Variables): Warn about special chars in CPPFLAGS.
5420 (Installation Directory Variables): Quote $(datadir) better.
5421 (Limitations of Builtins): Describe some of eval's trickiness.
5423 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Simplify quoting.
5424 * lib/autoconf/fortram.m4 (_AC_PROG_FC_V_OUTPUT): Likewise.
5425 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Put leading space
5426 in front of every arg, not just trailing args. Quote apostrophes.
5427 (_AC_EVAL_ECHO): New macro.
5428 (_AC_EVAL, AC_EVAL_STDERR): Use it. Quote arg of eval.
5429 (AC_TRY_EVAL, AC_TRY_COMMAND): Mention that these macros might get
5430 removed.
5431 (_AC_LINK_IFELSE): Use proper rule for shell continuation lines,
5432 exposed by quoting of eval argument. Put the command on line line
5433 so it logs better.
5434 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): Use eval more safely.
5435 (_AC_PATH_X, AC_PATH_X): Quote more safely.
5436 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Use eval more safely.
5437 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Don't use eval.
5438 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Minor style change.
5439 Handle special chars in prefix, ac_srcdir, ac_aux_dir.
5440 Use eval more safely.
5441 (_AC_OUTPUT_CONFIG_STATUS): Adjust to above changes.
5442 * lib/m4sugar/m4sh.m4 (AS_VAR_GET): Note that this API needs
5443 to be replaced.
5444 * tests/base.at (AC_TRY_COMMAND): Use proper rule for shell continuation
5445 lines, exposed by quoting of eval argument.
5447 2006-05-26 Stepan Kasal <kasal@ucw.cz>
5448 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5450 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Drop the
5451 initialization of `ac_cv_exeext', do not override it if it was
5452 already set, unless it was set to `no', for compatibility with
5453 Autoconf-2.13, and comment this.
5454 Do not export `ac_cv_exeext', Libtool hasn't needed this for years.
5455 (_AC_COMPILER_EXEEXT_DEFAULT): Likewise, do not export it.
5456 (_AC_COMPILER_EXEEXT_WORKS, _AC_COMPILER_EXEEXT_CROSS): Typos.
5457 * doc/autoconf.texi (Compilers and Preprocessors) <EXEEXT>:
5458 Document that this test may be overridden by setting
5459 `ac_cv_exeext'.
5461 2006-05-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5463 Revert these two patches:
5465 2006-04-06 Eric Blake <ebb9@byu.net>
5466 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_O): Inside cache
5467 check, s/ac_exeext/ac_cv_exeext/. Fixes regression introduced
5468 2006-04-01.
5470 2006-04-01 Stepan Kasal <kasal@ucw.cz>
5471 Clean up _AC_COMPILER_EXEEXT* macros.
5472 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't try to
5473 detect exeext, it will be done by _AC_COMPILER_EXEEXT_O; just set
5474 ac_file to the name of the default output file and call
5475 _AC_COMPILER_EXEEXT_WORKS. Move the definition of ac_files and the
5476 initial `rm' of the candidate files...
5477 (_AC_COMPILER_EXEEXT): ... here and simplify them. Moreover, use
5478 the same list in subsequent `rm' calls, and for the temporary
5479 redefinition of ac_clean_files; call _AC_COMPILER_OBJEXT at the end,
5480 and don't call the other _AC_COMPILER_EXEEXT_* macros directly, use...
5481 (_AC_COMPILER_EXEEXT_TESTS): ... this new macro.
5482 (_AC_COMPILER_EXEEXT_O): Don't export ac_cv_exeext, it's not needed (or
5483 no longer needed) by libtool. Make it a cache check.
5484 (_AC_COMPILER_EXEEXT_CROSS): Remove the comment, it was obviously
5485 copied here by mistake.
5486 (AC_NO_EXECUTABLES): Redefine _AC_COMPILER_EXEEXT_TESTS, not
5487 _AC_COMPILER_EXEEXT.
5488 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX, AC_PROG_OBJC): Do not call
5489 _AC_COMPILER_OBJEXT directly.
5490 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
5492 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5494 * doc/autoconf.texi (Limitations of Usual Tools) < sed (`t')>:
5495 Fix description of how the buggy `sed' works.
5497 2006-05-25 Noah Misch <noah@cs.caltech.edu>
5499 Sync from Automake:
5501 * lib/Autom4te/XFile.pm (lock): Allow EOPNOTSUPP, besides
5502 ENOLCK. Only mention `make -j' when applicable. Only raise
5503 fatal errors when `make -j' is involved. Improve error message.
5505 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5507 * doc/autoconf.texi (Here-Documents): We now know more about
5508 the variable expansion in here documents bug.
5509 Thanks to Tim Rice and Stepan Kasal.
5511 * doc/autoconf.texi (Making testsuite Scripts): Add an example
5512 how to use TESTSUITEFLAGS. Suggested by Eric Blake.
5514 2006-05-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5516 * tests/autotest.at (Multiline command from M4 expansion):
5517 No failure to be expected if the shell quotes newlines in
5518 commands in the `set -x' output. Report by Tim Rice.
5519 * THANKS: Update.
5521 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
5523 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Don't use shell
5524 expansion in the here-documents used by config.status, as that
5525 runs afoul of the Korn shell version M-12/28/93d bug described in
5526 the Autoconf manual, and this in turn causes a Coreutils 5.95 build to
5527 fail as described by Tim Rice and diagnosed by Ralf Wildenhues in
5528 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00082.html>.
5530 2006-05-23 Jim Meyering <jim@meyering.net>
5532 * lib/autoconf/functions.m4 (AC_FUNC_LSTAT_FOLLOWS_SLASHED_SYMLINK):
5533 Fix typo introduced with 2006-04-02 change. It reversed the sense
5534 of the test.
5536 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
5538 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Simplify ac_dA and
5539 ac_dB slightly, to save bytes in the script.
5540 Max out at 50 lines, rather than 96; this is more likely
5541 (though not guaranteed) to avoid obscure 'sed' failures.
5543 2006-05-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5545 * lib/autotest/general.m4 (AT_INIT): UnixWare `tr' may interpret
5546 `tr -d -' as bad option argument. Work around this by deleting
5547 an unrelated character.
5548 Report by Tim Rice <tim@multitalents.net>.
5550 2006-05-22 Paul Eggert <eggert@cs.ucla.edu>,
5551 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
5552 Stepan Kasal <kasal@ucw.cz>
5554 * doc/autoconf.texi (Particular Programs): Do not promise that
5555 we always prefer the GNU version of the program, and that we
5556 search according to PATH; both rules can have exceptions.
5557 Update description of AC_PROG_GREP, AC_PROG_EGREP, AC_PROG_FGREP,
5558 AC_PROG_SED. Move descriptions of limitations
5559 to the Limitations of Usual Tools section.
5560 (Limitations of Usual Tools) <sed>: Mention script length
5561 limitations with Solaris /usr/ucb/sed.
5562 <grep>: Fix wording for empty alternative. Mention that -c and
5563 -l should not be combined, and that -E and -F should not be
5564 combined.
5566 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
5567 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5569 * lib/autoconf/programs.m4 (AC_PROG_SED): Catch script length
5570 limits in Solaris 8 /usr/ucb/sed by testing a long script.
5572 2006-05-22 Stepan Kasal <kasal@ucw.cz>
5574 * doc/autoconf.texi (Defining Symbols): Literal parameter of
5575 AC_DEFINE is now passed to m4_pattern_allow.
5576 * NEWS: Mention that; likewise for AC_SUBST.
5577 * lib/autoconf/general.m4 (AC_DEFINE_TRACE_LITERAL): Pass
5578 the parameter to m4_pattern_allow.
5579 * tests/tools.at: Add a check for that.
5581 2006-05-22 Stepan Kasal <kasal@ucw.cz>
5583 * lib/autoconf/status.m4: Fix typos.
5585 2006-05-21 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5587 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Remove
5588 only the files that this macro generates.
5590 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
5592 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: For
5593 the HP-UX sed limitation of 99 commands, labels do not count.
5594 * lib/autoconf/status.m4 (_AC_SED_CMD_LIMIT): Mention that
5595 in the comment.
5596 (_AC_OUTPUT_HEADER): Revert the change from 2006-05-19.
5598 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
5600 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT):
5601 Import the following fix from coreutils:
5603 2006-01-13 Jim Meyering <jim@meyering.net>
5605 Invoke AC_CHECK_FUNCS(getmntent) unconditionally so that tests of
5606 $ac_cv_func_getmntent (e.g., in gl_LIST_MOUNTED_FILE_SYSTEMS) need
5607 not double-quote uses of that variable, to accommodate the rare
5608 case in which getmntent is available in none of the libraries
5609 checked. This happens at least on FreeBSD 5.0.
5611 2006-05-20 Paul Eggert <eggert@cs.ucla.edu>
5613 * lib/autoconf/general.m4 (AC_CONFIG_AUX_DIRS): Bring back
5614 ac_config_guess, ac_config_sub, and ac_configure, since evidently
5615 some other programs unwisely rely on these undocumented vars.
5616 But put in warning comments about them.
5617 Problem reported by Ralf Wildenhues in
5618 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00068.html>.
5619 * NEWS: Document that these variables are intended to go away.
5621 2006-05-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5623 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): Require AC_PROG_CXX,
5624 and set the language to C++ (analogous to the equivalent Fortran
5625 tests).
5627 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): New macro.
5628 * doc/autoconf.texi (C++ Compiler): Document it.
5629 * lib/autoconf/fortran.m4 (_AC_PROG_FC_C_O): Adjust comment.
5630 * NEWS: Update.
5632 2006-05-19 Paul Eggert <eggert@cs.ucla.edu>
5634 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Fix off-by-one bug
5635 that caused config.status to generate 100-command sed scripts; the
5636 portable limit is 99.
5638 2006-05-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5640 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Name temporary
5641 variable `ac_d' instead of `d' to avoid infringing namespace.
5642 Report by Ralf Menzel.
5644 2006-05-18 Paul Eggert <eggert@cs.ucla.edu>
5646 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Don't prepend
5647 $ac_top_build_prefix to $MKDIR_P if it's just 'mkdir -p'.
5648 * tests/tools.at (autoconf: subdirectories): New test, taken from
5649 the corresponding problem report by Ralf Wildenhues in:
5650 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00053.html
5652 * lib/autoconf/functions.m4 (AC_REPLACE_FNMATCH, AC_FUNC_FNMATCH_GNU):
5653 Quote some uses of shell variables if they might suffer unexpected
5654 globbing. This doesn't fix all instances of quoting problems that
5655 I found, just the easy ones that look safe.
5656 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR, _AC_INIT_HELP):
5657 (AC_CONFIG_AUX_DIR, AC_CONFIG_AUX_DIR_DEFAULT, AC_CONFIG_AUX_DIRS):
5658 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST, AC_CANONICAL_TARGET):
5659 (AC_CACHE_LOAD, AC_CACHE_SAVE): Likewise.
5660 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF, _AC_PATH_X_DIRECT): Likewise.
5661 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Likewise.
5662 * lib/autoconf/status.m4 (_AC_OUTPUT_LINK, _AC_OUTPUT_SUBDIRS):
5663 Likewise.
5664 * lib/autotest/general.m4 (_AC_INIT_PARSE_ARGS): Likewise.
5665 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Likewise.
5667 2006-05-18 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5669 * bin/autoreconf.in ($help): Reword according to the manual.
5670 Suggested by Olly Betts.
5672 2006-05-17 Olly Betts <olly@survex.com> (tiny change)
5673 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5675 * bin/autoreconf.in: Pass the directory argument to
5676 `require_configure_ac'. Fix comment.
5677 * tests/torture.at (Configuring subdirectories): Expose this.
5678 Reported by Olly Betts.
5680 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5682 * lib/Automake/Configure_ac.pm, lib/Automake/Channels.pm,
5683 lib/Automake/FileUtils.pm, lib/Automake/Struct.pm: Sync from
5684 Automake as follows:
5686 * lib/Autom4te/Configure_ac.pm (find_configure_ac): Use
5687 `$configure_in' instead of `configure.in', to preserve
5688 directory component.
5690 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5692 * config/config.guess, config/config.sub, config/texinfo.tex,
5693 doc/make-stds.texi, doc/standards.texi: Sync from upstream.
5695 2006-05-14 Paul Eggert <eggert@cs.ucla.edu>
5697 * lib/autoconf/headers.m4 (AC_HEADER_STDBOOL): Fix overly-picky
5698 test for C99 conformance; (bool) 0.5 is an integer constant
5699 expression, but (bool) -0.5 is not. Problem reported by Fedor
5700 Sergeev in <http://forum.sun.com/jive/thread.jspa?threadID=96202>.
5702 2006-05-13 Paul Eggert <eggert@cs.ucla.edu>
5704 * doc/autoconf.texi (Particular Programs): AC_PROG_MKDIR_P now
5705 sets MKDIR_P, not mkdir_p, to avoid collisions with Automake.
5706 Warn about obsolete install-sh files. Remove stray sentence
5707 fragment and fix cross reference.
5708 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Don't insist on
5709 install -d; this undoes the 2006-05-10 change.
5710 (MKDIR_P): Mark with AN_MAKEVAR.
5711 (AC_PROG_MKDIR_P): Fall back on $ac_install_sh, not $INSTALL, so
5712 that we don't require $INSTALL to be thread-safe. Move comments
5713 out of generated code. Require AC_CONFIG_AUX_DIR_DEFAULT instead
5714 of AC_PROG_INSTALL. Output a message saying that we're checking
5715 mkdir -p. Set MKDIR_P rather than mkdir_p. Do special magic for
5716 MKDIR_P instead of AC_SUBST.
5717 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE, _AC_OUTPUT_CONFIG_STATUS):
5718 Special magic for MKDIR_P, too.
5719 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Remove comment that defeated
5720 a dnl.
5721 * tests/local.at (AT_CHECK_ENV): mkdir_p -> MKDIR_P.
5723 2006-05-11 Paul Eggert <eggert@cs.ucla.edu>
5725 Sync from Automake, as follows:
5727 2006-05-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5728 * config/install-sh: Initialize IFS, so field splitting isn't
5729 turned off later.
5730 * config/mkinstalldirs: Likewise.
5731 * config/missing: Remove superfluous quotes. Replace all uses of
5732 `[' by `test', for consistency, and for..
5733 * config/missing (sed_minuso, sed_output): New variables.
5734 (autom4te, help2man, makeinfo): Use them. Unifies detection of
5735 `-o FILE', `--output FILE', `--output=FILE', stricter regex.
5736 Fixes `missing' to detect `--output' for help2man. Fixes
5737 PR automake/483. Report by Dennis J. Linse.
5738 (autom4te): Document in `missing --help'.
5740 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
5742 * NEWS: New macro AC_PROG_MKDIR_P. AS_MKDIR_P is now more robust.
5743 * config/install-sh: Don't use 'path' to talk about file names,
5744 as per GNU coding standards. Close a race condition reported by Ralf
5745 Wildenhues and Stepan Kasal. There is still a race condition
5746 on hosts that predate Posix 1003.1-1992, but we can't help this.
5747 Don't mishandle weird characters like space on pre-Posix hosts.
5748 Invoke mkdir at most once per dir arg on pre-Posix hosts.
5749 * doc/autoconf.texi (Programming in M4sh): Cross-reference to
5750 AC_PROG_MKDIR_P from AS_MKDIR_P.
5751 (Limitations of Usual Tools): Cross-reference to AC_PROG_MKDIR_P
5752 from mkdir. Mention that Autoconf 2.60 install-sh is safe but
5753 earlier editions are not (including Automake 1.8.3).
5754 Do not suggest mkinstalldirs for thread-safety.
5755 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Insist on an 'install'
5756 that understands -d, so that AC_PROG_MKDIR_P can fall back on $INSTALL.
5757 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Make it more robust in the
5758 presence of special characters and race conditions.
5759 * tests/local.at (AT_CHECK_ENV): Add mkdir_p to the list of variables
5760 in Autoconf's name space.
5762 2006-05-10 Bruno Haible <bruno@clisp.org>
5763 and Paul Eggert <eggert@cs.ucla.edu>
5765 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): New macro, taken
5766 from Automake with minor changes.
5767 * doc/autoconf.texi (Particular Programs): Document AC_PROG_MKDIR_P.
5769 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
5771 * config/install-sh: Update to Automake CVS version, as follows:
5772 2006-04-25 Stepan Kasal <kasal@ucw.cz>
5773 * lib/install-sh: Simplify the expr implementation of dirname.
5774 2006-04-24 Paul Eggert <eggert@cs.ucla.edu>
5775 * lib/install-sh: Handle --, and diagnose unknown options.
5777 2006-05-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5779 * tests/Makefile.am (AUTOTEST): Use `$(MY_AUTOM4TE)' instead of
5780 `./autom4te' to create `./testsuite', since the `all' target
5781 will ensure its presence, but `installcheck' should not create
5782 the uninstalled wrappers.
5784 * tests/torture.at (Unusual Automake input files): Skip if we
5785 detect automake < 1.8.
5787 2006-05-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5789 * lib/autoconf/c.m4 (AC_PROG_CC_STDC): If ac_cv_prog_cc_stdc
5790 is set to `no', then that overrides and sets ac_cv_prog_cc_c89
5791 and ac_cv_prog_cc_c99 to `no', for backward compatibility.
5792 * NEWS: Update.
5794 2006-05-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5796 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Take care not to
5797 munge (multiple) white space and other oddities.
5798 * tests/torture.at (AT_CHECK_AC_ARG_VAR): Make sure to M4-escape
5799 single quotes in variable assignment.
5800 (AC_ARG_VAR, configure invocation): Adjust tests to expose this
5801 and similar failures by adding multiple spaces, tabs, and other
5802 special characters.
5803 Report and different test suggested by Francesco Romani
5804 <fromani@gmail.com> and Andrew Church <achurch@achurch.org>.
5806 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): When we escape
5807 single quotes, we only need to search for single quotes; this
5808 both simplifies the search pattern, and makes us less
5809 susceptible to `echo' variations for arguments not containing
5810 single quotes.
5811 (_AC_ARG_VAR_VALIDATE): Likewise.
5813 2006-05-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5815 * doc/autoconf.texi (Special Shell Variables) <IFS>: Document
5816 `$*' and IFS concatenation issue with traditional shells and
5817 bash-2.04. Report by Seanster@Seanster.com.
5819 2006-05-03 Bruno Haible <bruno@clisp.org>
5821 * doc/autoconf.texi (Limitations of Usual Tools): Identify more
5822 precisely which Mac OS X versions have the od problem.
5824 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
5826 * doc/autoconf.texi: Use @option systematically.
5828 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
5829 and Bruno Haible <bruno@clisp.org>
5831 * doc/autoconf.texi (Limitations of Usual Tools): Add a paragraph
5832 about 'od'.
5833 (Integer Overflow): Mention the special case of integer division
5834 overflow.
5836 2006-05-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5838 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Cater for
5839 traditional shells like the Solaris one that do not use the
5840 first IFS character for assembling `$*'.
5841 Prompted by a related report from autoconf_bug@nro.ca.
5843 2006-05-01 Paul Eggert <eggert@cs.ucla.edu>
5844 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5846 * doc/autoconf.texi (Limitations of Builtins, Limitations of Make):
5847 Mention more problems with the -e option.
5849 2006-04-30 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5851 * NEWS: Typo.
5852 * doc/autoconf.texi (Systemology): Mention the Heirloom Project.
5854 * doc/autoconf.texi (Introduction, Pointers): Use `@/' liberally
5855 in URLs to improve DVI formatted output (requires texinfo 4.6).
5856 (System Services, Systemology, Shellology): Likewise.
5857 (Limitations of Usual Tools): Rewrite Mac OS X example for nicer
5858 output.
5860 * doc/autoconf.texi (Fortran Compiler): Do not use `@ovar' in
5861 continuous text.
5862 (Runtime): Fix macro argument names to match description:
5863 `action-if-found' -> `action-if-true' and similarly.
5864 (Obsolete Macros): Likewise.
5865 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE): Likewise.
5866 (AC_COMPILE_IFELSE, AC_TRY_COMPILE, _AC_LINK_IFELSE)
5867 (AC_LINK_IFELSE, AC_TRY_LINK, AC_COMPILE_CHECK): Likewise.
5869 2006-04-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5871 * doc/autoconf.texi (Limitations of Make): Clean up markup.
5873 * ChangeLog: Typo.
5874 * doc/autoconf.texi (Portable Shell): Allow wrapped URLs, for
5875 DVI output.
5877 2006-04-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5879 * doc/autoconf.texi (Limitations of Builtins): Document FreeBSD
5880 /bin/sh set unsorted output.
5881 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): Adjust.
5882 * tests/local.at: Likewise.
5884 2006-04-26 Paul Eggert <eggert@cs.ucla.edu>
5886 * doc/autoconf.texi (Portable C and C++, Varieties of Unportability):
5887 (Integer Overflow, Null Pointers, Buffer Overruns):
5888 (Floating Point Portability, Exiting Portably): New sections.
5889 (Writing Test Programs): Fix some langauge. Recommend exiting
5890 with status 1, not merely nonzero. Clarify exit declaration.
5891 (Run Time): Move C exit status stuff to new Exiting Portably section.
5892 (Systemology): Mention Posix and levenez. Update v7 reference.
5893 (Portable Shell): Mention the Posix shell.
5895 2006-04-25 Stepan Kasal <kasal@ucw.cz>
5897 * bin/autoconf.as (me): Replace by as_me.
5899 2006-04-25 Paul Eggert <eggert@cs.ucla.edu>
5901 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Don't use AS_ERROR,
5902 since as_me isn't set yet.
5904 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
5906 Prepare for deprecation of AS_BASENAME and AS_DIRNAME, and fix
5907 a few minor bugs in this area.
5909 * doc/autoconf.texi (Programming in M4sh): Comment out the
5910 documentation of AS_BASENAME, for now.
5911 (Shell Substitutions): Do not use AS_DIRNAME in an example.
5912 (Limitations of Builtins) <basename>: Do not refer to
5913 AS_BASENAME.
5914 * bin/autoconf.as (me): Don't use AS_BASENAME.
5915 (dir): Remove the unused variable.
5916 * lib/m4sugar/m4sh.m4 (_AS_DETECT_REQUIRED): Renamed from
5917 AS_DETECT_REQUIRED. All uses changed.
5918 (_AS_DETECT_SUGGESTED): Renamed from AS_DETECT_SUGGESTED.
5919 All uses changed.
5920 (_AS_DETECT_BETTER_SHELL): Put ;; at the end of a case.
5921 (AS_BASENAME): Use "basename --" to protect against leading "-".
5922 (_AS_BASENAME_EXPR): Renamed from AS_BASENAME_EXPR. All uses changed.
5923 (_AS_BASENAME_SED): Renamed from AS_BASENAME_SED. All uses changed.
5924 (_AS_BASENAME_PREPARE): Reject implementations that cannot handle "--".
5925 (_AS_DIRNAME_PREPARE): Likewise.
5926 (_AS_DIRNAME_EXPR): Renamed from AS_DIRNAME_EXPR. All uses changed.
5927 (_AS_DIRNAME_SED): Renamed from AS_DIRNAME_SED. All uses changed.
5928 (AS_DIRNAME): Use "dirname --".
5930 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
5932 * doc/autoconf.texi (Runtime): Renamed from "Run Time". All uses
5933 of "run time" and "run-time" changed to "runtime", for consistency.
5934 * lib/autoconf/fortran.m4: Likewise (in comment).

5936 * lib/autoconf/general.m4: Likewise.
5937 * lib/autoconf/headers.m4: Likewise.
5939 * doc/autoconf.texi (Run Time): Document the exit status situation
5940 with more accuracy and detail.
5942 2006-04-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5944 * doc/autoconf.texi (Introduction): The GNU Autoconf Macro
5945 Archive is not officially `GNU' any more. Update URL.
5946 (Defining Directories): Likewise
5947 * lib/autoconf/c.m4 (AC_C_RESTRICT): Update URL.
5949 2006-04-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5951 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Remove the leading
5952 newline from the `trap' code to finish `config.log'; the NetBSD
5953 /bin/sh resets the exit status after an empty command, as
5954 documented in doc/autoconf.texi.
5955 Reported by Dalibor Topic <robilad@kaffe.org>.
5957 2006-04-19 Paul Eggert <eggert@cs.ucla.edu>
5959 * doc/autoconf.texi (C Compiler): Clarify AC_C_TYPEOF.
5960 Suggested by Bruno Haible.
5962 2006-04-18 Paul Eggert <eggert@cs.ucla.edu>
5964 * configure.ac (ac_cv_sh_n_works): Don't try to test for it, since
5965 some shells (e.g., Solaris 8 /bin/sh) implement it verrrry slowly.
5966 Instead, just list the shells that we know work.
5967 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Remove 2nd arg. All uses
5968 changed. Be more cautious about the _cv_ variable.
5969 * tests/tools.at (Syntax of the shell scripts): Check the
5970 _cv_ variable once, at first, to avoid an internal autoconf error
5971 when sh -n does not work.
5973 2006-04-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5975 * lib/Autom4te/FileUtils.pm: Sync from Automake.
5977 2006-04-16 Paul Eggert <eggert@cs.ucla.edu>
5979 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Don't
5980 use ">&-" since we're only 99.999% sure that this is portable,
5981 and since the MinGW bug is fixed in a different way.
5982 * lib/autotest/general.m4 (AT_INIT): Likewise.
5984 2006-04-16 Stepan Kasal <kasal@ucw.cz>
5986 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Handle --recheck
5987 before opening config.log, to avoid hitting a bug on MinGW.
5989 2006-04-14 Paul Eggert <eggert@cs.ucla.edu>
5991 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Close
5992 AS_MESSAGE_LOG_FD before reopening it onto the log file.
5993 This works around a MinGW bug reported by Eric Paire.
5994 Make sure that all writes to the log file append to it,
5995 rather than possibly losing data.
5996 * lib/autotest/general.m4 (AT_INIT): Likewise.
5998 2006-04-14 Stepan Kasal <kasal@ucw.cz>
6000 * lib/Autom4te/FileUtils.pm (find_file): Fix a typo in the
6001 description.
6003 2006-04-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6005 * NEWS: Update.
6007 * configure.ac (AC_INIT): Bump to 2.59d.
6009 2006-04-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6011 Version 2.59c.
6013 * Makefile.maint (news-date-check): Do not require a leading `*'
6014 before the release date in NEWS.
6016 2006-04-12 Stepan Kasal <kasal@ucw.cz>
6017 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6019 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If the templates for
6020 the instantiated file do not contain the string 'datarootdir'
6021 but contain @datadir@, @docdir@, @infodir@, @localedir@, or
6022 @mandir@, replace the reference '${datarootdir}' by the value.
6023 * tests/torture.at (datarootdir workaround): New test.
6024 * NEWS: Advertise this temporary fixup.
6025 Based on a patch by Bruno Haible, reported and analyzed by
6026 Paul Eggert and Noah Misch.
6028 2006-04-12 Eric Blake <ebb9@byu.net>
6030 * tests/autotest.at (Debugging a failed test): Fix comment.
6032 2006-04-12 Stepan Kasal <kasal@ucw.cz>
6034 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): Simplify the summary of
6035 all the changes since 2006-04-07.
6037 2006-04-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6039 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): If `ln -s file1 file2'
6040 succeeded, but `ln -s file dir' failed, take care to remove the
6041 leftover target before the next test, to prevent its spurious
6042 failure; also make sure `ln file dir' works before selecting it.
6043 Thanks to Keith Marshall for pointing this out.
6044 * THANKS: Update.
6046 * lib/autotest/general.m4 (AT_INIT): Store quoted variable
6047 assignments in `at_debug_args', so that we put them correctly
6048 in the `run' script.
6049 * tests/autotest.at (Debugging a failed test): Unmark XFAIL.
6050 Reported by Eric Blake.
6052 2006-04-11 Eric Blake <ebb9@byu.net>
6054 * tests/autotest.at (AT_CHECK_AT): Add new argument, to allow
6055 top-level tests after micro-suite has been run. Used in...
6056 (Debugging a successful test, Debugging script and environment),
6057 (Debugging a failed test): ...these new tests. The first of these
6058 is fixed by...
6059 * lib/autotest/general.m4 (_AT_CREATE_DEBUGGING_SCRIPT): New
6060 macro, split out from...
6061 (AT_INIT): ...here, so that using -d also generates a run script.
6062 Document that -d inhibits top-level logging.
6063 * doc/autoconf.texi (testsuite Invocation): Document that -d only
6064 inhibits top-level logging; debug scripts are created.
6066 * lib/autotest/general.m4 (_AT_CHECK): Avoid syntax error on empty
6067 check.
6068 * tests/autotest.at (Empty test, Empty check): New test to check it.
6070 * lib/autoconf/c.m4 (AC_C_CONST, AC_C_VOLATILE): Avoid warnings
6071 from gcc.
6073 2006-04-10 Stepan Kasal <kasal@ucw.cz>
6075 * tests/mktests.sh: Use "trap '' 0", not "trap 0". Do not touch
6076 the files if a problem appears. Make the empty *.at files
6077 read-only, too. Proposed by Ralf Wildenhues.
6079 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6081 * config/Makefile.am: Add comment to force updated Makefile.in.
6083 * lib/freeze.mk: Fix typo in comment. Unlike the last, white
6084 space only patch to this file, this patch causes the Makefile.in
6085 files that include freeze.mk to be updated, and thus have a
6086 newer time stamp again, which in turn makes a pristine CVS
6087 checkout have correct time stamps.
6089 * Makefile.maint (cvs-sv): New macro, to be used..
6090 (config.guess-url_prefix, config.sub-url_prefix)
6091 (texinfo.tex-url_prefix, standards.texi-url_prefix): ..here;
6092 point to CVS text checkout of Gnulib files.
6093 (copyright-check): Bump current year.
6094 (announcement): Do not hard-wire `./announce-gen'.
6095 (cvs-update): Propagate failures of `cvs' and `move-if-change'
6096 correctly.
6097 * Makefile.cfg (executable-update): Use `chmod a+x' instead of
6098 `chmod +x'.
6099 (wget_files): Update config.guess, config.sub, texinfo.tex by
6100 `wget-update', now that their URLs work again.
6102 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
6104 * doc/autoconf.texi (Particular Types): Don't use AC_CHECK_TYPE.
6105 Problem noted by Paul D. Smith.
6107 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6109 * doc/autoconf.texi: Remove unused words from word list.
6110 * .x-sc_prohibit_atoi_atof, .x-sc_space_tab, .x-sc_sun_os_names,
6111 .x-sc_trailing_space: New files.
6113 * doc/standards.texi: Sync from gnulib.
6115 * NEWS, doc/autoconf.texi (AC_LIBOBJ vs LIBOBJS): Mark
6116 `LIBOBJDIR' as experimental.
6118 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): MSYS `ln -s' fails
6119 with a target directory; it's internally implemented as `cp'
6120 anyway, but since Autoconf advertises the possibility to use
6121 a target directory when LN_S is `ln -s', we need to find out.
6122 Reported by Rolf Ebert <rolf.ebert.gcc@gmx.de> against MSYS,
6123 analyzed by Keith Marshall <keith.marshall@total.com>.
6125 * THANKS: Update.
6127 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
6129 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Just output
6130 confdefs.h as-is. In general, if it has backslash-newline or the
6131 like, then it doesn't work either to sort or to remove empty
6132 lines.
6134 2006-04-09 Stepan Kasal <kasal@ucw.cz>
6136 * tests/Makefile.am (AUTOCONF_FILES): Fix typo in the comment.
6138 2006-04-09 Alexandre Duret-Lutz <adl@gnu.org>
6140 * lib/autom4te.in (Automake-preselections): Preselect
6141 _AM_SUBST_NOTMAKE.
6143 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>
6145 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Use '\'' for an
6146 apostrophe within a single-quoted string, as this is the usual
6147 tradition and is easier to read than '"'"'. Don't rely on the
6148 shell treating "$/" like '$/'. Use a more-consistent indenting
6149 style for the trap.
6151 2006-04-09 Eric Blake <ebb9@byu.net>
6153 * tests/autotest.at (Backquote command substitution),
6154 (Multiline backquote command substitution): Remove mistaken
6155 AT_NO_CMDSUBST from the 2006-03-14 patch, which was meant to be
6156 applied...
6157 (Parenthetical command substitution, Multiline parenthetical
6158 command substitution): here.
6160 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>

6178 (Generic Functions): Add AC_CHECK_FUNCS_ONCE. Refer to new
6179 Gnulib section.
6180 (Particular Headers): Add AC_HEADER_ASSERT. For stdbool.h,

6190 AC_TYPE_INTMAX_T, AC_TYPE_INTPTR_T, AC_TYPE_LONG_DOUBLE,
6191 AC_TYPE_LONG_DOUBLE_WIDER, AC_TYPE_LONG_LONG_INT, AC_TYPE_UINT8_T,
6192 AC_TYPE_UINT16_T, AC_TYPE_UINT32_T, AC_TYPE_UINT64_T,
6193 AC_TYPE_UINTMAX_T, AC_TYPE_UINTPTR_T, AC_TYPE_UNSIGNED_LONG_LONG_INT.
6194 (C Compiler): Move AC_C_LONG_DOUBLE to ...
6195 (Obsolete Macros): here. Under AC_LONG_DOUBLE, mention
6196 AC_TYPE_LONG_DOUBLE or AC_TYPE_LONG_DOUBLE_WIDER instead.
6197 (Posix Variants): Add AC_USE_SYSTEM_EXTENSIONS.
6198 (Coding Style). Don't mention m4_expand_once.
6199 * lib/autoconf/c.m4 (AC_C_LONG_DOUBLE): Implement via
6200 AC_TYPE_LONG_DOUBLE_WIDER. Now obsolete.
6201 * lib/autoconf/functions.m4 (_AH_CHECK_FUNCS): New macro.

6209 Catch a bug in IBM AIX xlc compiler version 6.0.0.0.
6210 Catch a bug in an HP-UX C compiler.
6211 * lib/autoconf/specific.m4 (AC_USE_SYSTEM_EXTENSIONS): New macro.

6216 (_AC_STRUCT_DIRENT, AC_STRUCT_DIRENT_D_INO, AC_STRUCT_DIRENT_D_TYPE):
6217 New macros.
6219 * tests/mktests.sh (ac_exclude_list, au_exclude_list): Do not
6220 use /^foo|bar$/, it does not mean /^(foo|bar)$/.
6222 2006-04-08 Stepan Kasal <kasal@ucw.cz>
6224 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Fix the wording
6225 of the warning introduced by the 2001-08-28 change.
6227 2006-04-08 Stepan Kasal <kasal@ucw.cz>,

6230 * lib/autoconf/general.m4 (AC_CACHE_SAVE): All `ac_cv_env_foo'
6231 variables shall be overriden by the cache.

6233 that contains braces.
6235 2006-04-07 Stepan Kasal <kasal@ucw.cz>
6237 Revert the patch from 2006-04-01 and only improve
6238 _AS_DETECT_BETTER_SHELL:
6240 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Do not optimize; do not
6241 skip nonexistent directories.
6242 (_AS_DETECT_BETTER_SHELL): The optimization is moved here--try
6243 only shell candidates which exist.
6244 (AS_UNAME): No need to give three parameters to _AS_PATH_WALK.
6245 * lib/autotest/general.m4 (AT_INIT): No need to give three
6246 parameters to _AS_PATH_WALK.
6248 2006-04-07 Stepan Kasal <kasal@ucw.cz>,
6249 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6251 * bin/autoupdate.in (handle_autoconf_patches): Change the way we
6252 distinguish m4sugar macros.
6253 * tests/tools.at (autoupdating with aclocal and m4_include):
6254 New test. Bug reported by Gary V. Vaughan <gary@gnu.org>,
6255 test case by Noah Misch <noah@cs.caltech.edu>.
6257 2006-04-07 Stepan Kasal <kasal@ucw.cz>
6259 Revert my change from 2006-03-17, in other words:
6260 * lib/m4sugar/m4sh.m4 (AS_BOURNE_COMPATIBLE): Insert BIN_SH=xpg4
6261 and DUALCASE=1.
6262 (AS_SHELL_SANITIZE): Remove DUALCASE=1.
6263 * doc/autoconf.texi (Special Shell Variables) <BIN_SH>: Say that
6264 it is set.
6266 2006-04-07 Eric Blake <ebb9@byu.net>
6268 * doc/autoconf.texi (Programming in M4sh): Document that
6269 AS_MKDIR_P exits the script on failure.
6270 * lib/autotest/general.m4: Remove redundant AS_ERROR.
6272 2006-04-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6274 * config/elisp-comp, config/install-sh, config/mdate-sh,
6275 config/missing, config/mkinstalldirs: Sync from Automake.
6277 * lib/Autom4te/FileUtils.pm, lib/Autom4te/Struct.pm: Sync
6278 from Automake.
6280 * doc/make-stds.texi: Sync from gnulib.

6284 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_O): Inside cache
6285 check, s/ac_exeext/ac_cv_exeext/. Fixes regression introduced

6288 2006-04-06 Stepan Kasal <kasal@ucw.cz>,
6289 Eric Blake <ebb9@byu.net>,
6290 Paul Eggert <eggert@cs.ucla.edu>,
6291 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6293 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): Fix the detection of
6294 whether `set' quotes correctly: redirect stderr of the tested
6295 `set', and use a subshell, for Ultrix; use `sed' instead of
6296 `grep' for zsh `set' which may write binary output; match only
6297 at the beginning of a line, to avoid false positives.
6298 In order to avoid false positives by unrelated variables with
6299 multiline content, put the dump algorithm in a subshell and
6300 unset all variables containing newlines (except some which are
6301 special to the shell). Warn about cache variables that are
6302 unset.
6304 2006-04-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6306 * config/config.guess, config/config.sub, config/texinfo.tex:
6307 Sync from upstream.
6309 * tests/mktests.sh: Reword comments.
6311 * tests/mktests.sh: Only skip internal macros starting with
6312 `_AC_' or `__AC_'. Noted by Stepan Kasal.
6313 Update exclusion lists for the test suite to this end:
6314 (AC_ARG_VAR): Do test this now.
6315 (AC_SEARCH_LIBS, AC_REPLACE_FUNCS): Need an argument.
6316 (AC_LINKER_OPTION): Remove (renamed to _AC_LINKER_OPTION).
6317 (AC_LIST_MEMBER_OF): Likewise (renamed to _AC_LIST_MEMBER_IF).
6318 (AC_LINK_FILES): Obsoleted since (and thus AU_DEFUN'ed).
6320 * doc/autoconf.texi (Shell Substitutions): Mention the MSYS
6321 shell issue with double-quoted command substitutions of native
6322 commands.
6323 Reported to MSYS by Mark Cave-Ayland, to Autoconf by Keith
6324 Marshall.
6326 * Makefile.maint (sc_cast_of_argument_to_free): Do not fail when

6332 (m4-check): Likewise.
6333 (sc_system_h_headers): Do not print rule on execution.
6334 (sc_tight_scope): Do not fail for non-existing `src' directory.
6335 (sc_changelog): Skip the Copyright footer.
6336 * lib/autoconf/lang.m4: Remove trailing space.
6338 * lib/autoconf/status.m4: More replacements to
6339 <tab><space> where this makes sense.
6341 2006-04-06 Stepan Kasal <kasal@ucw.cz>
6343 * tests/Makefile.am (maintainer-check-posix):
6344 s/POSIXLY_CORRECTLY/POSIXLY_CORRECT/
6346 * lib/autoconf/status.m4 (_AC_CONFIG_FOOS): Append TAGS to
6347 ac_config_<foo>s again, sometimes normalized, sometimes not.
6348 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_LINKS):
6349 (AC_CONFIG_COMMANDS): Do not do so here.
6350 (_AC_CONFIG_REGISTER_DEST): Double quote the tags in macros _AC_LIST_TAGS
6351 and_AC_LIST_TAG_COMMANDS; fixes another regression introduced by the
6352 2005-07-25 rewrite. Noticed by Noah Misch.
6354 * lib/autoconf/general.m4 (AC_PRESERVE_HELP_ORDER): Do not define
6355 _AC_PRESERVE_HELP_ORDER, ...
6356 (AC_ARG_ENABLE, AC_ARG_WITH): ... use AC_PROVIDE_IFELSE insetad.
6358 * lib/autoconf/general.m4 (AC_ARG_VAR): Do not use m4_divert_once
6359 inside m4_expand_once; it is redundant.
6361 * lib/autoconf/general.m4 (_AC_INIT_HELP): Remove the broken support
6362 for --help from Cygnus `configure.'
6364 2006-04-06 Paul Eggert <eggert@cs.ucla.edu>
6366 * doc/autoconf.texi (C Compiler): Warn about #error. Follows up
6367 on a patch proposed by Ralf Wildenhues.
6369 2006-04-05 Paul Eggert <eggert@cs.ucla.edu>
6371 * lib/autoconf/status.m4: Replace <space>''<tab> with
6372 <tab><space> where this makes sense.
6374 2006-04-05 Howard Chu <hyc@highlandsun.com> (trivial change)
6375 Noah Misch <noah@cs.caltech.edu>
6377 * lib/autoconf/general.m4 (AC_PRESERVE_HELP_ORDER): New macro.
6378 (AC_ARG_ENABLE, AC_ARG_WITH): Adjust.
6379 * doc/autoconf.texi (Help Formatting): New node.
6380 * NEWS: Announce AC_PRESERVE_HELP_ORDER.
6382 2006-04-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6384 * TODO, config/Makefile.am, lib/freeze.mk, lib/autoconf/c.m4,
6385 lib/autoconf/specific.m4, lib/autoconf/status.m4,
6386 lib/autoconf/types.m4, lib/autotest/general.m4,
6387 tests/mktests.sh, tests/torture.at: White space cleanup:
6388 remove some SPACE before TAB, or add quoting ('' or @&t@).
6390 * NEWS, TODO, bin/autoreconf.in: `filesystem' -> `file system'.
6392 * doc/autoconf.texi (Shell Substitutions): Document `^' vs. `|'.
6394 2006-04-05 Eric Blake <ebb9@byu.net>
6396 * lib/autotest/general.m4 (AT_INIT): Prep AT_*_all, so that an
6397 empty test suite works.
6398 * tests/autotest.at (Empty test suite): Remove xfail.
6400 2006-04-05 Noah Misch <noah@cs.caltech.edu>
6402 * lib/autoconf/status.m4 (_AC_CONFIG_FOOS): Do not append normalized
6403 TAGS to ac_config_<foo>s.
6404 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_LINKS): Do so here.
6405 (AC_CONFIG_COMMANDS): Append NAME to ac_config_commands without
6406 normalizing it, consistent it with previous releases.
6407 * tests/torture.at (Macro calls in AC_CONFIG_COMMANDS tags): New test.
6409 2006-04-05 Paul Eggert <eggert@cs.ucla.edu>
6411 * lib/m4sugar/m4sh.m4 (AS_BASENAME_EXPR, AS_DIRNAME_EXPR):
6412 Use simplified args that Eric Blake originally suggested.
6414 2006-04-04 Paul Eggert <eggert@cs.ucla.edu>
6416 * tests/mktests.sh: Don't use 'cat'; just read the files directly.
6417 Prefer 'sort -u' to 'sort | uniq'. Filter data before sorting it.
6418 Use 'comm' rather than N instances of grep; this also fixes a bug
6419 whereby substrings were incorrectly matched, causing us to not
6420 generate tests for AC_F77_NAME_MANGLING and AC_FUNC_LSTAT.
6421 (exclude_list): Exclude empty macros.
6422 (ac_exclude_list): Exclude AC_INCLUDES_DEFAULT.
6424 Use awk rather than grep -E or egrep, to avoid
6425 portability problems with regular expressions containing newlines.
6426 (exclude_list, ac_exclude_list, au_exclude_list, ac_exclude_script):
6427 Switch from grep to awk syntax.
6428 (ac_exclude_script): Renamed from ac_exclude_egrep.
6429 (au_exclude_script): Renamed from au_exclude_egrep.
6431 2006-04-04 Noah Misch <noah@cs.caltech.edu>
6433 * lib/autoconf/general.m4 (_AC_INIT_HELP): Only `configure.in' evidences
6434 a subdirectory subject to Cygnus `configure'.
6435 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Likewise.
6437 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): Omit the bug
6438 report request when we have no AC_PACKAGE_BUGREPORT.
6440 2006-04-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6442 * THANKS: Update.
6444 * tests/mktests.sh: Update copyright year in the header of the
6445 generated files.
6447 * lib/autoconf/c.m4 (AC_C_INLINE): Do not skip cleanup code.
6448 (AC_C_RESTRICT): Likewise. Furthermore, add a function with a
6449 typedef'ed restricted pointer, to catch a compiler bug on
6450 HP-UX 11.x, and fix warnings so it passes with -Werror.
6451 (_AC_PROG_CC_C99): Likewise.
6452 Reported by Albert Chin <china@thewrittenword.com>.
6453 * tests/mktests.sh: Do not skip AC_C_INLINE, AC_C_RESTRICT.
6455 2006-04-03 Noah Misch <noah@cs.caltech.edu>
6457 * bin/autoscan.in (subdirs): New global.
6458 (scan_file): Prune directories with configure{,.{ac,in,gnu}}.
6459 (output): Emit AC_CONFIG_SUBDIRS as needed.
6460 * tests/autoscan.at (autoscan): Remove XFAIL.
6462 2006-04-03 Noah Misch <noah@cs.caltech.edu>
6464 * lib/autoconf/general.m4 (AC_CACHE_SAVE): Use AC_MSG_NOTICE.
6466 2006-04-03 Eric Blake <ebb9@byu.net>
6468 * THANKS: Add myself.
6470 2006-04-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

6508 _AC_COMPILER_EXEEXT_WORKS. Move the definition of ac_files and the
6509 initial `rm' of the candidate files...
6510 (_AC_COMPILER_EXEEXT): ... here and simplify them. Moreover, use
6511 the same list in subsequent `rm' calls, and for the temporary
6512 redefinition of ac_clean_files; call _AC_COMPILER_OBJEXT at the end,
6513 and don't call the other _AC_COMPILER_EXEEXT_* macros directly, use...
6514 (_AC_COMPILER_EXEEXT_TESTS): ... this new macro.
6515 (_AC_COMPILER_EXEEXT_O): Don't export ac_cv_exeext, it's not needed (or

6596 switch all of them on and of when necessary. Fixes the bug when
6597 m4sugar macros (e.g., m4_define) were expanded after the first
6598 automatic update (e.g., after AC_PREREQ or AC_INIT).
6600 2006-03-31 Paul Eggert <eggert@cs.ucla.edu>

6854 _AC_SUBST_FILES fragment. Separate `{' and `r' commands by
6855 newline for portability.
6856 * tests/torture.at (Torturing config.status): Also test 100

7297 (AC_LANG_FUNC_LINK_TRY(C)): Call the function rather than simply
7298 comparing its address. Intel's interprocedural optimization was

7316 2005-10-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7317 Stepan Kasal <kasal@ucw.cz>
7319 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Balance parentheses.
7320 * lib/autotest/general.m4 (AT_INIT): If the test dir already exists,
7321 make its content writable before removing it. Remove an errorneous
7322 comment from the end, where the logs of the failed tests are copied
7323 to the main log file.
7325 2005-09-27 Stepan Kasal <kasal@ucw.cz>

7332 problems if the testsuite were running too fast.
7334 2005-09-18 Paul Eggert <eggert@cs.ucla.edu>

7348 suggested by Ben Elliston. Handle weird characters correctly.
7350 2005-09-06 Stepan Kasal <kasal@ucw.cz>
7352 * lib/autoconf/libs.m4 (AC_SEARCH_LIBS): Merge the two AC_LINK_IFELSE
7353 calls, so that the final expansion of this macro is shorter.
7354 Create the conftest.$ac_ext outside the `for' loop, to speed the run.
7355 Do not use `break' in the argument to AC_LINK_IFELSE, it would skip
7356 the cleanup there. Use AS_VAR_* macros, to be more general.
7357 * tests/semantics.at (AC_SEARCH_LIBS): Check for the cleanup.
7359 * lib/autoconf/general.m4: Use AS_IF where appropriate.
7361 * lib/m4sugar/m4sh.m4 (AS_IF): Use m4_default.

7379 2005-08-26 Stepan Kasal <kasal@ucw.cz>
7381 * doc/autoconf.texi (Programming in M4sh) <AS_TR_CPP>: Fix m4 quoting
7382 in the example. Reported by Bruno Haible.
7383 <AS_TR_SH>: Likewise. Also modify the example to be more convincing:
7384 "if $undefined_var;" succeeds with my shell.
7386 * lib/autoconf/general.m4 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST,
7387 AC_CANONICAL_TARGET): Define by AC_DEFUN, no need to use AC_DEFUN_ONCE;
7388 but change the m4_divert_text to m4_divert_once.

7393 Work around bug in Solaris /usr/xpg4/bin/awk.
7394 The bug is present in at least Solaris 8 through 10.
7396 2005-08-24 Stepan Kasal <kasal@ucw.cz>
7398 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Simplify; rejecting
7399 some evil values and relying on the fact that $* concatenates the
7400 parameters by the first character from IFS.
7402 2005-08-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
7403 Stepan Kasal <kasal@ucw.cz>

7408 Update limitations about when to call AC_CONFIG_HEADERS.
7409 (Configuration Commands): Document that AC_CONFIG_COMMANDS_PRE
7410 parameter can call AC_SUBST, AC_DEFINE, or AC_CONFIG_FOOS; explain
7411 that AC_CONFIG_COMMANDS_PRE and AC_CONFIG_COMMANDS_POST are not
7412 ``Configuration Actions''; fix their index entries.
7414 * lib/autotest/general.m4 (AT_INIT): Process multiple keywords
7415 options correctly. Process N-M as M-N if M is smaller than N.
7416 Process ranges correctly so that N-N will run only N.
7417 Sort and uniquify the tests that will be run. If there is more
7418 than one test, reinsert the banners for the tests.
7419 * tests/autotest.at (Keywords): Unmark XFAIL.
7421 2005-08-23 Stepan Kasal <kasal@ucw.cz>
7423 * lib/autoconf/general.m4 (_AC_DEFINE_Q): Strip the parameter list
7424 before passing the macro name to AH_TEMPLATE.
7426 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): config.status
7427 now opens log after option processing; in particular, --version
7428 and --help do not touch config.log.
7430 * Makefile.maint: Revert the change from 2005-08-12.
7432 2005-08-22 Stepan Kasal <kasal@ucw.cz>

7445 Prepend to LIBS, not append, in examples.
7447 2005-08-16 Stepan Kasal <kasal@ucw.cz>
7449 When building in place, set srcdir="."; suggested by Tim Van Holder.
7451 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Do this; to recognize
7452 build in place, we need ac_pwd, and thus have to AC_REQUIRE ...
7453 (_AC_INIT_DIRCHECK): ... this macro and AC_DEFUN both of them.
7454 * lib/autoconf/status.m4 (_AC_SRCDIRS): Fix a comment: srcdir="."

7468 * Makefile.maint (GZIP_ENV): When checking the help text of gzip,
7469 add "2>&1"; gzip 1.2.4 prints help on stderr.
7471 2005-07-27 Stepan Kasal <kasal@ucw.cz>
7473 * lib/autotest/general.m4 (_AT_DECIDE_TRACEABLE): The symbol at_reason
7474 was pushdef'ed twice while popped only once. Push it only once.

7486 * lib/m4sugar/m4sugar.m4 (m4_strip): Comment fix---change tab to
7487 "<tab>" in comment, so that the point is understandable.
7489 2005-07-25 Stepan Kasal <kasal@ucw.cz>
7491 Rewrite substantial part of lib/autoconf/status.m4.
7492 The main change is that CONFIG_FILES, CONFIG_HEADERS, CONFIG_LINKS,
7493 and CONFIG_COMMANDS are not processed in four separate loops.
7494 Instead, there is one main loop. This alows that the common code
7495 is expanded only once, thus config.status (and configure) is smaller.
7497 The registration mechnism in AC_CONFIG_FILES and cousins also changed;
7498 the AC_LIST_FILES and cousins macros are no longer used.
7500 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES, _AC_OUTPUT_HEADERS,
7501 _AC_OUTPUT_LINKS, _AC_OUTPUT_COMMANDS): Renamed to ...
7502 (_AC_OUTPUT_FILE, _AC_OUTPUT_HEADER, _AC_OUTPUT_LINK,
7503 _AC_OUTPUT_COMMAND): ..., respectively. These macros no longer
7504 contain the initialization, nor the for loop, nor the associated
7505 commands; all these go to ...
7506 (_AC_OUTPUT_MAIN_LOOP): ... this new macro, called from
7507 _AC_OUTPUT_CONFIG_STATUS.
7508 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST, _AC_CONFIG_SPLIT_FILE_IN):
7509 Nuked; the code was merged into _AC_OUTPUT_MAIN_LOOP.
7510 (_AC_OUTPUT_FILE): The creation of the sed script ...
7511 (AC_OUTPUT): ... and the setup of ac_vpsub goes to ...
7512 (_AC_OUTPUT_FILES_PREPARE): ... a new macro, also called from
7513 _AC_OUTPUT_MAIN_LOOP.
7514 (_AC_CONFIG_FILES, _AC_CONFIG_HEADERS, _AC_CONFIG_LINKS,
7515 _AC_CONFIG_COMMANDS): Use ...
7516 (_AC_CONFIG_FOOS): ... this new macro, which uses these ...
7517 (_AC_CONFIG_REGISTER, _AC_CONFIG_REGISTER_DEST): ... new macros.
7518 (_AC_CONFIG_FILE, _AC_CONFIG_HEADER, _AC_CONFIG_LINK,
7519 _AC_CONFIG_COMMAND, _AC_CONFIG_DEPENDENCIES): No longer needed.
7520 (_AC_CONFIG_DEPENDENCY): Update, it uses these ...
7521 (_AC_CONFIG_DEPENDENCY_DEFAULT, _AC_FILE_DEPENDENCY_TRACE_COLON):
7522 ... new macros.
7523 (_AC_CONFIG_UNIQUE): Update.
7524 (AC_LIST_FILES, AC_LIST_HEADERS, AC_LIST_LINKS, AC_LIST_COMMANDS):
7525 Replaced by this ...
7526 (_AC_LIST_TAGS): ... new common macro.
7527 (AC_LIST_FILE_COMMANDS, AC_LIST_HEADER_COMMANDS, AC_LIST_LINK_COMMANDS,
7528 AC_LIST_COMMAND_COMMANDS): Replaced by this ...
7529 (_AC_LIST_TAG_COMMANDS): ... new common macro.
7530 (_AC_CONFIG_COMMANDS_INIT): Moved top to the `registration' section;
7531 this didn't belong to the `config commands' section.
7532 (_AC_OUTPUT_COMMANDS_INIT): Don't initialize, m4_ifdef is our friend.
7533 (AC_CONFIG_COMMANDS_PRE, AC_OUTPUT_COMMANDS_PRE,
7534 AC_CONFIG_COMMANDS_POST): Moved to a new section, these didn't belong
7535 to the `config commands' section either.
7536 (AC_CONFIG_SUBDIRS): Don't touch diversion DEFAULTS.
7537 (_AC_LIST_SUBDIRS): Don't initialize, m4_ifdef is our friend.
7539 ... and many changes to the comments nearby.
7541 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): At the end of the day,
7542 set ac_subdirs_all='_AC_LIST_SUBDIRS'.
7543 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
7544 AC_CONFIG_COMMANDS(command:input,...) is no longer allowed.
7545 (#define header templates): The comment at the top of the generated
7546 header now includes the name(s) of the source file(s).
7548 Several unrelated small changes:
7550 * lib/autoconf/general.m4 (AC_CACHE_VAL): Be didactic, quote the first
7551 parameter to AC_DIAGNOSE.
7552 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS): Likewise.
7553 (_AC_LINK_FILES_CNT): Don't AU_DEFUN this; it causes confusing messages
7554 with autoupdate; use m4_define_default inside AU_DEFUNed AC_LINK_FILES.
7555 (AC_OUTPUT): In the compatibility code, use m4_ifvaln, to be consistent
7556 with AU::AC_OUTPUT.
7557 (AU::AC_OUTPUT): Don't double-quote $2 and $3, the compatibility code
7558 in AC_OUTPUT doesn't double-quote it either.
7559 * tests/tools.at (autoupdate): AU::AC_OUTPUT no longer double-quotes the
7560 parameters.
7562 2005-07-10 Stepan Kasal <kasal@ucw.cz>
7564 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Document which
7565 versions of Portland Group compiler produce single- and double-quoted
7566 -cmdline argument. Reported by Steven G. Johnson <stevenj@fftw.org>
7567 and Ole Holm Nielsen <Ole.H.Nielsen@fysik.dtu.dk>.
7569 2005-07-07 Paul Eggert <eggert@cs.ucla.edu>
7571 * tests/local.at (AT_CONFIG_CMP): Ignore lines like "LIBS=''" too.
7572 This is a corrected version of yesterday's patch.
7574 2005-07-07 Stepan Kasal <kasal@ucw.cz>
7576 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Report the full
7577 path, too; insert a "===" to emphasize the line.
7579 * lib/autoconf/general.m4 (AC_CANONICAL_BUILD): Rename
7580 ac_cv_build_alias to ac_build_alias.
7581 (AC_CANONICAL_HOST, AC_CANONICAL_TARGET): Simplify.
7583 On 2005-02-24, an unintentional AC_SUBST([CC]) was introduced; this
7584 change eliminates it. Problem reported by Alexandre Duret-Lutz.
7585 * lib/autoconf/general.m4 (_AC_ARG_VAR_PRECIOUS): Move the AC_SUBST ...
7586 (AC_ARG_VAR): ... here.
7587 (_AC_INIT_PREPARE): Call AC_SUBST for build_alias, host_alias and
7588 target_alias.
7590 Keep a list of all precious variables and process them with one simple
7591 for loop, instead of expanding all commands, or, OTOH, complicated
7592 processing of output of "set".
7593 * lib/autoconf/general.m4 (_AC_ARG_VAR_PRECIOUS): Acumulate the
7594 variable names in new macro...
7595 (_AC_PRECIOUS_VARS): ... which will be assigned to ac_precious_vars.
7596 (_AC_ARG_VAR_STORE): New macro which writes to diversion PARSE_ARGS
7597 a loop to assign all ac_env_* and ac_cv_env_* variables.
7598 (_AC_ARG_VAR_VALIDATE): Use shell variable ac_precious_vars, divert
7599 to INIT_PREPARE.
7600 (_AC_INIT_DEFAULTS): At the end, if _AC_PRECIOUS_VARS is set, assign
7601 its value to shell variable ac_precious_vars and call
7602 _AC_ARG_VAR_STORE and _AC_ARG_VAR_VALIDATE.
7603 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Don't call
7604 _AC_ARG_VAR_VALIDATE.
7606 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Move AC_LANG_PUSH(C)
7607 and the AC_SUBSTs ...
7608 (AC_INIT): ... here.
7610 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Changed the title of
7611 the ac_subst_files section in config.log.
7613 * tests/local.at (AT_CONFIG_CMP): Revert Paul's previous change.

7622 Fix problems reported by Nicolas Joly.
7623 * tests/base.at (Input/Output): Ignore 'loading site script' chatter.
7624 * tests/local.at (AT_CONFIG_CMP): Ignore lines like "LIBS=''" too.
7625 They are generated by the Tru64 v5.1B shell.
7627 2005-07-05 Stepan Kasal <kasal@ucw.cz>
7629 Fix my changes from 2005-07-01; reported by Noah Misch.
7630 * lib/autoconf/status.m4 (_AC_CONFIG_DEPENDENCIES): Fix the
7631 description, the macro now accepts only a single tag.
7632 (_AC_CONFIG_UNIQUE): Likewise; s/AC_File/[$1]/
7634 Fix cases when the varsions of Autoconf and Autotest don't match.
7635 Reported by Noah Misch.
7636 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Set also
7637 at_top_builddir, for compatibility with older autotest.
7638 * lib/autotest/general.m4 (AT_INIT): If at_top_build_prefix
7639 is not set, use at_top_builddir, for compatibility with older
7640 versions of autoconf.
7642 2005-07-04 Paul Eggert <eggert@cs.ucla.edu>
7644 * bin/autom4te.in ($m4): Catch usages like --nesting-limit=2048.
7645 Problem reported by Patrick Welche.
7647 2005-07-03 Paul Eggert <eggert@cs.ucla.edu>
7649 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Use &, not |, in
7650 sed substitution command, so that we allow | in program prefixes
7651 and program suffixes. (& is a problem anyway; we're not fixing
7652 that here.)
7653 * lib/autoconf/status.m4 (AC_CONFIG_FILES): Likewise, for
7654 configure_input, top_builddir, srcdir, etc.
7655 * lib/autotest/general.m4 (AT_INIT): Likewise, for
7656 PATH_SEPARATOR in AUTOTEST_PATH.
7658 2005-07-02 Alexandre Duret-Lutz <adl@gnu.org>
7660 * lib/autoconf/general.m4 (AC_SITE_LOAD): Rewrite the
7661 for loop over config.site files using `set', to allow
7662 directory names containing IFS characters.
7664 2005-07-01 Paul Eggert <eggert@cs.ucla.edu>
7666 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Remove the tests for
7667 directories with weird names. Apparently some people like living
7668 on the edge. However, improve the test that "pwd" actually does
7669 report a name for the working directory.
7670 * NEWS: Remove the claim that we test for funny chars in dir names.
7672 2005-07-01 Stepan Kasal <kasal@ucw.cz>

7685 (Generic Functions): Mention the Gnulib project.
7686 (Limitations of Usual Tools) <sed>: Another minor rephrasing.
7688 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Use a here
7689 document to output the default config_* lists to config.status.
7690 Don't recognize option --file, if the functionality is not there.
7691 Likewise for --header; moreover, recognize --he and --h as shortcuts
7692 for --help in that case.
7694 * lib/autoconf/status.m4: Fix the order of the "sections", so that it
7695 matches the order of execution. No code changed.

7716 * lib/autoconf/general.m4 (AC_SUBST_TRACE): New macro, to be traced
7717 instead of AC_SUBST; proposed by Alexandre Duret-Lutz.
7718 (AC_SUBST): Call it.
7719 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Call AC_SUBST_TRACE for
7720 the directory specific variables; but don't call it for configure_input.
7722 2005-06-28 Derek Price <derek@ximbiot.com>
7724 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: Reword recent
7725 addition.
7727 2005-06-23 Paul Eggert <eggert@cs.ucla.edu>
7729 * NEWS: Don't worry about spaces in bindir etc. Only srcdir and working
7730 directory have inherent problems with special characters like spaces,
7731 due to limitations in Make syntax. Problem reported by Alexandre
7732 Duret-Lutz.
7733 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Implement the above.
7734 Also, fix Tru64 porting problem with shell patterns,

7746 from Justace Clutter.
7747 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Put name of invalid
7748 variable into diagnostic. Make the diagnostic an error, not a warning,
7749 because we really don't support spaces and suchlike in dir names.
7750 (_AC_INIT_SRCDIR): Allow special characters in $ac_unique_file.
7751 Don't worry about backslashes in srcdir; it can't happen now.

7753 Simplify ac_optarg handling.
7754 (_AC_ARG_VAR_VALIDATE): Remove unnecessary and inconsistent quotes.

7762 (AT_CONFIG_CMP): Use sed instead of grep plumbing.
7764 * doc/autoconf.texi (Limitations of Usual Tools) <grep>: Mention
7765 that '\|' is not allowed in BREs; recommend using newline separated
7766 list of patterns instead of multiple -e options.
7768 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Remove an old comment.
7770 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Use AC_SUBST/2.

7778 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: Document that
7779 b, t, r, w commands require single space, while : cannot have any.
7780 (Special Shell Variables): Fix sed code this in the example.
7781 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Likewise; and fix a typo.
7782 * lib/autotest/general.m4 (AT_ARG_OPTION): Fix typo in the description.
7784 * lib/m4sugar/m4sugar.m4 (m4_split): If the parameter is empty,
7785 expand to the empty list. Don't use two pairs of m4_changequote,
7786 it's not necessary.
7788 2005-06-20 Derek Price <derek@ximbiot.com>
7790 * lib/m4/programs.m4 (AC_PROG_YACC): Declare YACC & YFLAGS precious.
7792 2005-06-17 Paul Eggert <eggert@cs.ucla.edu>
7794 * lib/m4sugar/m4sh.m4 (as_awk_strverscmp): Port to Solaris /bin/awk.
7795 * doc/autoconf.texi:
7796 Don't mention Solaris versions so much, if a
7797 problem is common to all extant versions of Solaris. Say "SunOS
7798 4" instead of "SunOS" for SunOS 4.
7799 (awk): Mention more of the limitations of traditional Awk.
7800 (cat): Don't talk about cat -v.
7802 2005-06-16 Paul Eggert <eggert@cs.ucla.edu>
7804 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE): New macro.
7805 (AS_VERSION_COMPARE): New macro. The API is taken from CVS,

7807 to be compatible with glibc strverscmp.
7808 * tests/m4sh.at (AS_VERSION_COMPARE): New test.
7810 * doc/autoconf.texi (Limitations of Usual Tools): Mention expr bug
7811 on Mac OS X 10.4 reported by Peter O'Gorman in:
7812 http://lists.gnu.org/archive/html/autoconf-patches/2005-06/msg00041.html
7813 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT):
7814 Use shell builtins rather than 'expr', to work around expr bug.
7816 2005-06-10 Paul Eggert <eggert@cs.ucla.edu>
7818 * doc/autoconf.texi: "filesystem" -> "file system".
7819 "behaviour" -> "behavior".
7820 Warn about \(...\)* in Solaris sed (written by Ralf Menzel).
7821 * lib/autoconf/general.m4: Omit blank after ":" sed command,
7822 as per POSIX.

7832 * lib/m4sugar/m4sh.m4 (AS_VAR_TEST_SET): Work even if $1 contains
7833 quotes and backslashes. Patch from Derek Price.

7842 * lib/autotest/general.m4 (AT_INIT): Don't accept Solaris 9's diff
7843 -u, since it outputs chatter if the input files are the same.
7844 Problem reported by Ralf Menzel.
7846 2005-06-08 Derek Price <derek@ximbiot.com>
7848 * lib/m4sugar/m4sugar.m4: Undefine include & sinclude rather than
7849 renaming them since they are about to be redefined anyhow.
7851 2005-06-08 Derek Price <derek@ximbiot.com>
7853 * doc/autoconf.texi (Redefined M4 Macros): Add index entries for most
7854 redefined M4 macros to this node. Document m4_include & m4_sinclude.
7855 Move m4_undefine to alphabetical order.
7857 2005-06-07 Paul Eggert <eggert@cs.ucla.edu>
7859 * README: Recommend GNU M4 1.4.3 or later.
7860 * doc/autoconf.texi (Introduction): Likewise.
7861 Reword to avoid some formatting glitches.
7862 Use "#!/bin/sh", not "#! /bin/sh"; the space isn't needed these days.
7863 Clarify explanation of HP compiler bug.
7864 Redo example output tp match current CVS snapshot.
7865 Use @example.org in email addresses when the examples
7866 might get inadvertently cut-and-pasted into user code.
7867 Remove example of autom4te usage that doesn't seem to work now.
7868 Use modern AC_INIT (except when the example is meant to be
7869 shown with Autoconf 2.13).
7870 Update ksh info for Solaris 9 and later.
7871 KB -> kB.
7872 Modernize description of Automake versions a bit.
7873 Don't claim a future version of Autoconf is near.
7874 * doc/install.texi: Reword to avoid some formatting glitches.
7876 2005-06-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7878 * doc/autoconf.texi: Add [] to examples, so that the manual
7879 follows its own advice about quoting better.
7880 Reword to avoid some formatting glitches.
7881 * doc/installt.exi: Reword to avoid some formatting glitches.
7883 * doc/autoconf.texi (Limitations of Builtins) <case>: Mention
7884 Tru64 ksh pattern matching bug. Reported against Libtool by
7885 Albert Chin <libtool@mlists.thewrittenword.com> and
7886 Nicolas Joly <njoly@pasteur.fr>.
7888 2005-06-06 Stepan Kasal <kasal@ucw.cz>
7890 m4_cdr of one-member list was [[]] (one-member list containing an
7891 empty string) instead of [] (an empty list. Callers were skewed to
7892 match this misbehaviour. As a consequence of this:
7893 - m4_foreach([x], [], [foo]) expanded to `foo', while
7894 - the expansion of m4_foreach([x], [[]], [foo]) was empty.
7895 This bug has been fixed:
7897 * lib/m4sugar/m4sugar.m4 (m4_cdr): If only one argument is given,
7898 expand to an empty string; print error msg if called without
7899 an argument list.
7900 (m4_foreach, m4_map, m4_map_sep): Don't expect the previous
7901 misbehaviour; handle [] and [[]] correctly.
7903 2005-06-06 Stepan Kasal <kasal@ucw.cz>
7905 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Nuke ac_max_here_lines.
7906 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Simplify the sed
7907 scripts created and the loop applying them, use _AC_SED_CMD_LIMIT.
7909 2005-06-06 Ralf Menzel <menzel@ls6.cs.uni-dortmund.de> (trivial change)
7911 * doc/autoconf.texi (Limitations of Usual Tools): Solaris' awk cannot
7912 swallow records with more than 99 fields.
7913 * lib/autotest/general.m4 (AT_INIT): Use the awk builtin `split' to
7914 parse the long line.
7916 2005-06-04 Stepan Kasal <kasal@ucw.cz>
7918 * doc/autoconf.texi (Limitations of Usual Tools): AIX awk cannot
7919 swallow literals longer than 399. Reported by Ralf Wildenhues.
7920 * lib/autotest/general.m4 (AT_INIT): Pass $at_groups though stdin,
7921 to workaround this limitation.
7923 2005-06-03 Steven G. Johnson <stevenj@alum.mit.edu>
7925 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Find g95 in addition
7926 to gfortran, and make these the first two compiler names
7927 checked (following the general autoconf preference for gcc).
7929 2005-06-03 Stepan Kasal <kasal@ucw.cz>
7931 * tests/Makefile.am (check_SCRIPTS): Set to $(wrappers).
7932 (DISTCLEANFILES): Remove $(check_SCRIPTS).
7933 (testsuite): Make sure autotest.m4f is up-to-date before using it.
7935 2005-06-02 Paul Eggert <eggert@cs.ucla.edu>
7937 * lib/autotest/general.m4 (AT_INIT): Don't create a regular
7938 expression of unbounded size when processing the --list
7939 option. This runs afoul of a limit of 399 bytes per regular
7940 expression on AIX. Problem reported by Ralf Wildenhues.
7942 2005-06-01 Paul Eggert <eggert@cs.ucla.edu>
7944 * NEWS: Note yesterday's changes to AC_SUBST and AC_SUBST_FILE.
7945 * doc/autoconf.texi (Particular Headers): Reword example
7946 for multiline stdbool replacement.
7947 (Setting Output Variables): Reword text a bit. Don't
7948 give all the details about |#_!!_#|.
7949 Reword description of line replacement.
7951 2005-05-31 Dan Manthey <dan_manthey@partech.com>
7953 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Output variables may
7954 now contain newlines, and substituted files must be referenced on
7955 a line alone; the sed scripts to substitute them are now very
7956 different.
7957 (_AC_SED_CMD_LIMIT): Added; single place to store limit on how many
7958 commands can be put in a sed script portably.
7959 * doc/autoconf.texi (Setting Output Variables): Document above
7960 changes. (Particular Header Checks) <AC_HEADER_STDBOOL>: Give exaple
7961 use of multiline substitution.
7962 * tests/torture.at: No longer expect substitution of newline to fail.
7964 2005-05-27 Paul Eggert <eggert@cs.ucla.edu>
7966 * lib/m4sugar/m4sh.m4 (_AS_SHELL_FN_WORK): Fix diagnostics.
7967 From Ralf Menzel (trivial change).
7969 2005-05-25 Paul Eggert <eggert@cs.ucla.edu>
7971 * tests/local.at: Don't attempt to check for negated character
7972 classes in shell scripts. The test was too brittle.
7974 2005-05-25 Stepan Kasal <kasal@ucw.cz>
7976 * bin/autoconf.as: Don't use "shift 2"; it's not portable enough.
7977 * doc/autoconf.texi (Limitations of Builtins): Document this
7978 limitation.
7980 2005-05-24 Stepan Kasal <kasal@ucw.cz>
7982 * lib/m4sugar/m4sh.m4 (_AS_ECHO_LOG): New macro to factor out
7983 common code; used in many places in the tree.
7984 (AS_ESCAPE): Make the pattern a bit simpler; use \& insetad of \1.
7985 (_AS_ECHO_UNQUOTED): Move the macro lower; no code change.
7987 * lib/m4sugar/m4sugar.m4 (m4_ifset): Use m4_ifval.
7989 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Merge the two error
7990 messages when ac_unique_file is not found.
7991 (AC_CONFIG_MACRO_DIR): Simplify the `if' at the end.
7992 (AC_MSG_CHECKING, AC_MSG_RESULT): Put braces around the two echo
7993 commands, for consistency with AC_MSG_ERROR and such.
7995 * bin/autoconf.as: Make more use of "shift 2" in option processing.
7997 * bin/Makefile.am: Merge the two rules for creating scripts.
7999 2005-05-23 Stepan Kasal <kasal@ucw.cz>
8001 * lib/autoconf/general.m4 (AC_MSG_RESULT_UNQUOTED): Make
8002 obsolete; it was never documented.
8003 (AC_CACHE_CHECK): Use AC_MSG_RESULT instead.
8005 2005-05-20 Stepan Kasal <kasal@ucw.cz>
8007 * NEWS: @top_builddir@ is now a dirname, ac_top_builddir will follow.
8008 * lib/autoconf/status.m4 (_AC_SRCDIRS): Rename ...
8009 (ac_top_builddir): ... this ...
8010 (ac_top_build_prefix): ... to this; the old name is also kept, for
8011 backward compatibility.
8012 (ac_top_builddir_sub): New variable, without the trailing slash,
8013 always nonempty.
8014 (_AC_OUTPUT_FILES): s/@top_builddir@/$ac_top_builddir_sub/
8015 * doc/autoconf.texi (Configuration Actions): Rename
8016 ac_top_builddir to ac_top_build_prefix.
8017 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Rename
8018 at_top_builddir to at_top_build_prefix.
8019 * lib/autotest/general.m4 (AT_INIT): Likewise.
8021 2005-05-20 Stepan Kasal <kasal@ucw.cz>
8023 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Simplify the init
8024 of confdefs.h .
8026 2005-05-17 Stepan Kasal <kasal@ucw.cz>
8028 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Don't m4_quote the second
8029 argument to m4_foreach. I guess it was necessary in the past,
8030 but I think it's a no-op now.
8032 2005-05-17 Stepan Kasal <kasal@ucw.cz>
8034 * lib/autoconf/general.m4 (_AC_INIT_HELP): Merge two consecutive
8035 ``cat <<_ACEOF'' commands to one.
8036 (_AC_CANONICAL_SPLIT): Use expr, not ``echo|sed.''
8037 * lib/autoconf/status.m4: On various places, use expr instead of
8038 ``echo|sed.''
8039 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST):
8040 (_AC_CONFIG_SPLIT_FILE_IN): New macros, to factor out common code.
8041 * lib/autotest/general.m4 (AT_INIT): Use expr to get the numbers from
8042 a range.
8043 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Use awk to search for
8044 the wrong patterns between ``case'' and ``esac.'' The previous
8045 code had false positives.
8047 2005-05-14 Alexandre Duret-Lutz <adl@gnu.org>
8049 * lib/autoconf/functions.m4 (_AC_LIBOBJ_ALLOCA): Prepend ${LIBOBJDIR},
8050 as on 2005-05-02.
8051 * doc/autoconf.texi (Particular Functions) <AC_FUNC_ALLOCA>:
8052 Mention LIBOBJDIR.

8092 2005-05-13 Stepan Kasal <kasal@ucw.cz>
8094 * lib/autoconf/general.m4 (AC_CONFIG_LIBOBJ_DIR): Remove the broken
8095 check.
8096 * lib/m4sugar/m4sugar.m4 (m4_bmatch): Halt with error if we don't get
8097 enough arguments, similarly as in m4_bpatsubsts.
8099 2005-05-12 Stepan Kasal <kasal@ucw.cz>
8101 * lib/autoconf/status.m4 (_AC_SRCDIRS): Simplify the computation

8104 2005-05-11 Stepan Kasal <kasal@ucw.cz>
8106 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Make the check
8107 for absolute directory names in one loop.
8108 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Handle
8109 abbreviations of --version and --debug.
8111 2005-05-10 Paul Eggert <eggert@cs.ucla.edu>
8113 * doc/autoconf.texi (Autoconf Language): Be more precise about
8114 quoting rules. Problems noted by Stepan Kasal.
8115 Also, throughout this document, be more careful about white space.
8116 "blank", "white space", and "space" all have different meanings
8117 and we should be careful to say what we mean.
8119 2005-05-05 Paul Eggert <eggert@cs.ucla.edu>
8121 Fix C++ related problems reported by Werner Lemberg.
8122 * doc/autoconf.texi (C++ Compiler): Mention .cpp extension.
8123 * lib/autoconf/c.m4 (AC_LANG(C++)): Set ac_ext to .cpp, not .cc.
8124 * lib/autoconf/types.m4 (AC_TYPE_SIGNAL): Simplify test, to
8125 avoid problems with C++ and throw.
8126 * tests/compile.at: .cpp, not .cc.
8128 * tests/semantics.at: Prepend LIBOBJDIR, as per 2005-05-02 change.
8130 2005-05-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8132 * doc/autoconf.texi (Generic Functions): Typos.
8134 2005-05-02 Gary V. Vaughan <gary@gnu.org>
8136 * lib/autoconf/general.m4 (_AC_LIBOBJS_NORMALIZE): Prepend each
8137 object named in LIBOBJS and LTLIBOBJS with the ${LIBOBJDIR}, as
8138 set by latest automake.
8140 2005-05-01 Paul Eggert <eggert@cs.ucla.edu>
8142 * doc/autoconf.texi (Limitations of Usual Tools): "expr '' \| ''"
8143 outputs 0 on GNU/Linux these days.
8145 2005-04-29 Paul Eggert <eggert@cs.ucla.edu>
8147 * doc/autoconf.texi (Autoconf Language): Add more description
8148 about quoting heuristics.
8149 (Limitations of Builtins): Describe "set -" problems.
8151 2005-04-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8153 * lib/autotest/general.m4 (AT_KEYWORDS): Separate by space,
8154 not newline.
8156 * doc/autoconf.texi (External Software): Replace AC_DEFINE_UNQUOTED
8157 by AC_DEFINE; it was a mistake.
8158 From bug reported against libtool by Dalibor Topic <robilad@kaffe.org>.
8160 2005-04-25 Stepan Kasal <kasal@ucw.cz>
8162 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): A tiny optimization.
8164 2005-04-22 Stepan Kasal <kasal@ucw.cz>
8166 * doc/autoconf.texi (External Software): Quadrigraphs are not
8167 processed correctly in AS_HELP_STRING; avoid this in the examples.
8168 * lib/m4sugar/m4sh.m4 (AS_HELP_STRING): Add a FIXME about quadrigraphs.
8169 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Likewise; and rephrase the
8170 comment and reduce m4_default([foo], []) to [foo].
8171 (m4_strip): Update the explanation.
8173 2005-04-19 Paul Eggert <eggert@cs.ucla.edu>
8175 * lib/autoconf/general.m4 (_AC_INIT_PREPARE, _AC_RUN_IFELSE):
8176 Remove core.conftest.* too; it's generated by Tru64 5.1.
8177 Problem reported by Jennis Pruett.
8178 * lib/autoconf/functions.m4
8179 (AC_FUNC_SETVBUF_REVERSED, AC_FUNC_UTIME_NULL):
8180 Don't bother to remove core files; AC_RUN_IFELSE should do that
8181 for you.
8183 2005-04-19 Stepan Kasal <kasal@ucw.cz>
8185 * lib/m4sugar/m4sugar.m4 (m4_bpatsubsts): Add the b- to comment, too.
8187 2005-04-19 Alexandre Duret-Lutz <adl@gnu.org>
8189 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Handle --docdir.

8202 2005-04-13 Paul Eggert <eggert@cs.ucla.edu>
8204 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Look for configure.ac
8205 as well as configure.in. Problem reported by Gregorio Guidi.
8207 2005-04-10 Paul Eggert <eggert@cs.ucla.edu>
8209 * doc/autoconf.texi (Particular Functions): Use gnulib's current

8223 fails if %s isn't supported. Problem reported by Ralf Wildenhues.
8225 2005-03-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8227 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS):
8228 Merge `-z option' as well for the benefit of Solaris link flags. Pass
8229 whole-archive (-zallextract, -zdefaultextract) options in the hope of
8230 unique libraries, for the Sun Fortran 95 8.0 compiler. Bug reported
8231 against Libtool by Yury Puhalsky <pooh@cryptopro.ru>.
8233 2005-03-22 Paul Eggert <eggert@cs.ucla.edu>
8235 * NEWS: The configure command now warns you if you attempt to use
8236 a directory whose name contains a special character like space,
8237 newline, or "\".
8238 * doc/autoconf.texi (Installation Directory Variables): Allow
8239 "," in file names. Do not use \@; it's not a portable regexp.
8240 * bin/Makefile.am (edit): Likewise.
8241 * lib/Makefile.am (edit): Likewise.
8242 * tests/Makefile.am (edit): Likewise.
8243 * tests/semantics.at: Likewise.
8244 * tests/torture.at: Likewise.
8245 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Likewise.
8246 * lib/autoconf/status.m4 (_AC_SRCDIRS): Likewise.
8247 * doc/autoconf.texi (File System Conventions): Warn about
8248 unportable file names.
8249 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): New macro.
8250 (AC_INIT): Use it.
8251 (_AC_INIT_SRCDIR): Use ac_pwd rather than invoking pwd.
8252 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Propagate
8253 ac_pwd, and quote srcdir.
8254 * lib/autotest/general.m4 (AT_INIT): Quote file name args.
8256 * doc/autoconf.texi: Fix some systematic formatting problems.
8257 ".)" needs a following @: if not at the end of a sentence, and
8258 similarly for "!)". "etc." should be preceded by a comma.
8259 "n-th" -> "@var{n}th". pdksh is still buggy, so update its date.
8261 2005-03-22 Bruno Haible <bruno@clisp.org>
8263 * doc/autoconf.texi (Input): Mention that AC_CONFIG_AUX_DIR's
8264 argument is often called 'build-aux'.
8266 2005-03-07 Stepan Kasal <kasal@ucw.cz>
8268 * doc/autoconf.texi (Quotation Rule Of Thumb): Mention that the
8269 macro AC_TRY_LINK is obsolete.
8270 (Installation Directory Variables): Change `AC_OUTPUT_FILES' to
8271 `AC_CONFIG_FILES'.
8273 2005-02-24 Stepan Kasal <kasal@ucw.cz>
8275 * lib/autoconf/c.m4 (AC_PROG_CC): Be more careful to skip
8276 `/usr/ucb/cc'; use `cl.exe' to distinguish the MS compiler
8277 from a Common Lisp's `cl'.
8278 (AC_PROG_CXX): Behave according to the documentation: don't
8279 search for $ac_tool_prefix$CCC and $CCC, just set CXX=$CCC;
8280 make the variable CCC precious; use `cl.exe', not `cl'.
8282 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
8283 Alexandre Duret-Lutz <adl@gnu.org>
8285 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin from
8286 /dev/null, as "configure" shouldn't read stdin, and this insulates
8287 us from problems (e.g., when testing for "cl"). Also, do this
8288 redirection before invoking "hostname" or "uname", and keep the
8289 original input stream available via...
8290 (AS_ORIGINAL_STDIN_FD): ... this new macro.
8291 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't
8292 bother with "</dev/null" since it's now done at the top of
8293 'configure'.
8294 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Likewise.
8295 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
8296 * lib/autoconf/programs.m4 (_AC_PATH_PROG_FLAVOR_GNU): Likewise.

8301 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
8303 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N_PREPARE): Don't set ECHO_C to
8304 newline if neither \c nor -n work, as that would output two
8305 newlines. Prefer -n to \c. Reported by Stepan Kasal.
8307 2005-02-12 Stepan Kasal <kasal@ucw.cz>
8309 * lib/m4sugar/m4sh.m4 (AS_IF): Define by m4_defun, not m4_define.
8310 This causes that any required macros inside will get before the if.
8311 * doc/autoconf.texi (autom4te.cache): A typo.
8313 2005-02-12 Paul Eggert <eggert@cs.ucla.edu>
8315 Undo previous change, except keep the change to
8316 lib/autoconf/programs.m4 that replaced grep with shell
8317 pattern-matching. This is because net-snmp configure reads stdin.
8318 Reported by Noah Misch.
8320 2005-02-11 Paul Eggert <eggert@cs.ucla.edu>
8322 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin
8323 from /dev/null, as "configure" shouldn't read stdin, and this
8324 insulates us from problems (e.g., when testing for "cl").
8325 Suggested by Alexandre Duret-Lutz. Also, do this redirection
8326 before invoking "hostname" or "uname".
8327 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
8328 _AC_LINK_IFELSE): Undo previous change, as it's no longer needed.
8329 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Don't bother with
8330 "</dev/null" since it's now done at the top of 'configure'.
8331 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
8332 * lib/autoconf/programs.m4 (_AC_PATH_PROG_FLAVOR_GNU): Likewise.
8333 Also, replace grep with shell pattern-matching, to save a process.
8335 2005-02-10 Paul Eggert <eggert@cs.ucla.edu>
8337 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
8338 _AC_LINK_IFELSE): Redirect stdin to /dev/null, in an attempt to
8339 avoid thinking that Allegro Common Lisp's "cl" command is a C++
8340 compiler.
8342 2005-02-09 Paul Eggert <eggert@cs.ucla.edu>
8344 * doc/autoconf.texi (Limitations of Usual Tools): Document that

8346 Problem reported by Dan Manthey.
8348 2005-02-08 Paul Eggert <eggert@cs.ucla.edu>
8350 * doc/autoconf.texi (Special Shell Variables): Clarify
8351 PATH_SEPARATOR wording; fix typo in IFS. Reported by Gary V. Vaughan.
8353 2005-02-07 Paul Eggert <eggert@cs.ucla.edu>
8355 * doc/autoconf.texi: Use @acronym for DJGPP.
8356 Fix some @code's that should have been @env's, and vice versa.
8357 Sort environment variable names.
8358 Mention that shells no longer inherit IFS.
8359 Don't recommend PATH_SEPARATOR=';' so strongly.
8360 Mention that $RANDOM might expand to the empty string.
8361 "symlink" and "soft link" -> "symbolic link".
8362 Improve mktemp description (reported by Bruno Haible).
8364 2005-02-05 Paul Eggert <eggert@cs.ucla.edu>

8374 * NEWS: Mention AT_COPYRIGHT.
8376 * tests/local.at (AT_CMP): Use diff directly on input files rather
8377 than copying them.
8379 * lib/autoconf/programs.m4 (AC_PROG_SED): Don't look in
8380 /usr/xpg4/bin since that sed dumps core (at least on Solaris 8).

8398 excess test name quoting.
8399 * tests/semantics.at (AC_CHECK_HEADERS_OLD, AC_CHECK_HEADERS_NEW): Pass
8400 CPPFLAGS to `configure' instead of setting it in `configure'.
8402 * lib/m4sugar/m4sh.m4 (AS_UNAME): Try only /usr/bin/hostinfo, not
8403 any `hostinfo' in $PATH, since hostinfo.exe is a popular file name
8404 on some platforms.

8435 2005-02-03 Paul Eggert <eggert@cs.ucla.edu>
8437 * lib/m4sugar/m4sugar.m4 (m4_re_escape): Escape ?, ^, \, $ too;
8438 this fixes a bug tickled by the AT_CAPTURE_FILE change noted below.
8440 Try not to generated lines of unlimited length, as POSIX places a
8441 2047-byte limit on line length of portable text files.
8442 * lib/autoconf/general.m4 (AC_SUBST, AC_SUBST_FILE):
8443 Use newline as a separator, not space.

8446 space.
8448 2005-02-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8450 * lib/m4sugar/m4sh.m4 (_AS_SHELL_FN_WORK): Move func_* to
8451 as_func_*. Add test to check whether positional parameters
8452 are restored after function return.
8454 2005-02-02 Paul Eggert <eggert@cs.ucla.edu>
8456 * doc/autoconf.texi (Special Shell Variables): Mention _,
8457 BIN_SH, DUALCASE. Say that variables other than "status" are safe
8458 if they contain a lower-case letter. The DUALCASE problem was
8459 reported by Ralf Wildenhues.
8461 * bin/autoconf.as: Don't exit with status 0 after write failure
8462 with --help or --version.

8476 * man/Makefile.am (.x.1): Go back to the simple solution, but take
8477 care to echo the commands, so the user knows what's going on.
8478 Modified from a suggestion by Stepan Kasal.
8480 * doc/autoconf.texi (autoreconf Invocation): Mention autopoint,

8501 Simplify the implementation of m4_require (a.k.a. AC_REQUIRE).
8502 Update the long comment explaining it.
8504 m4_require no longer writes an ``is required by'' line to the
8505 execution stack. It contains only one bit of non-redundant
8506 information: that the macro was required, not called. And even
8507 this bit is useless in most situations: have you ever met a macro
8508 which both calls and requires the same macro?
8510 * lib/m4sugar/m4sugar.m4 (_m4_defun_pro): Don't push a diversion...
8511 (_m4_defun_pro_outer): ... only via this macro, for the outermost
8512 macro.

8514 (m4_expansion_stack_pop): Remove the misplaced comment.
8515 (m4_require): Don't put the ``is required by'' line to the
8516 execution stack; slightly improve the out-of-a-defun error message.
8517 (_m4_divert_grow): New macro, counter for the temporary diversions.
8518 (_m4_require_call): Use it.
8519 * tests/m4sugar.at (m4_require): Expect output without the
8520 ``is required by'' messages.
8522 2005-01-28 Paul Eggert <eggert@cs.ucla.edu>
8524 * doc/autoconf.texi (Limitations of Usual Tools): Recommend X
8525 rather than x for expr.
8527 * lib/autoconf/lang.m4 (_AC_COMPILER_OBJEXT): Avoid subshells when
8528 this is safe.
8529 * lib/autoconf/programs.m4 (AC_PROG_EGREP, AC_PROG_FGREP): Likewise.
8530 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Likewise.

8540 * lib/Autom4te/Channels.pm, lib/Autom4te/Configure_ac.pm
8541 * lib/Autom4te/FileUtils.pm, lib/Autom4te/XFile.pm: Update
8542 from masters, so that FileUtils.pm's update_file provide --force
8543 support.
8544 * bin/autoheader.in: Pass $force to update_file so that
8545 config.h.in is always recreated when --force.
8547 2005-01-24 Stepan Kasal <kasal@ucw.cz>
8549 * doc/autoconf.texi (Introduction): Update Peter Simons' address.
8551 2005-01-21 Paul Eggert <eggert@cs.ucla.edu>
8553 * doc/autoconf.texi (Limitations of Builtins): Clarify that
8554 "if test ! -d foo; ..." is portable. Suggested by Stepan Kasal.
8556 2005-01-20 Paul Eggert <eggert@cs.ucla.edu>
8558 * doc/autoconf.texi (Shell Substitutions): Fix typo in case statement.
8559 Warn about newline stripping in `` and $(). Update Solaris
8560 version to 9.
8561 (Limitations of Builtins): Use expr "X...", not expr "x...", as
8562 X insulates us from future changes to Posix.
8563 (Limitations of Usual Tools): For AS_DIRNAME, warn about newline
8564 stripping.
8566 2005-01-19 Stepan Kasal <kasal@ucw.cz>
8568 * doc/autoconf.texi (Defining Symbols): Delete the false comment that
8569 you cannot use AC_DEFINE to define macros containing `[' or `]'.
8571 2005-01-13 Paul Eggert <eggert@cs.ucla.edu>
8573 * doc/autoconf.texi (Limitations of Usual Tools): Document bug

8584 ulongval to be static, to avoid unwanted GCC warning. Problem
8585 reported by Michael Jennings via Daniel Reed; see
8586 <https://bugzilla.redhat.com/beta/show_bug.cgi?id=143852>.
8588 2005-01-05 Alexandre Duret-Lutz <adl@gnu.org>
8590 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Define datarootdir,

8595 new variables.
8597 2005-01-04 Noah Misch <noah@cs.caltech.edu>
8599 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): If the Make program does
8600 not seem to work, assume it does set $(MAKE).

8612 (_m4_divert_n_stack): New macro; the expansion is
8613 <newline>m4_divert_stack, if m4_divert_stack is defined, and void
8614 otherwise.
8615 (m4_divert, m4_divert_push, m4_divert_pop, m4_init): Use it.
8616 (m4_divert_push, m4_divert_pop, _m4_defun_epi): Don't expand the word
8617 stored in _m4_divert_diversion or _m4_divert_dump.
8618 (m4_divert_pop): When the parameter is given, compare the symbolic
8619 name with the last diversion pushed on the stack. Previously, the
8620 current diversion was compared with the numeric value of the
8621 diversion given as the parameter.
8622 (m4_require): If the macro hasn't been expanded yet, call ...
8623 (_m4_require_call): this new macro.

8654 2004-12-30 Noah Misch <noah@cs.caltech.edu>
8656 * bin/autoreconf.in (autoreconf_current_directory): AM_INIT_AUTOMAKE
8657 signals that the package uses Automake; a `Makefile.am' is typical but
8658 not essential. Reported by Magnus Therning.
8659 * tests/torture.at (autoreconf.): New banner.
8660 (autoreconf and non-AC configure): Rename to `Non-Autoconf
8661 AC_CONFIG_SUBDIRS'.

8705 AT_LINE is used for log files.
8707 2004-12-21 Stepan Kasal <kasal@ucw.cz>
8709 * lib/autoconf/status.m4: Quote ``$tmp'' in many places.
8710 * lib/m4sugar/m4sh.m4 (AS_TMPDIR): Fix the comment, as traps are
8711 no longer part of the macro, quote the occurrence of ``$tmp''.

8930 * lib/autoconf/functions.m4 (AC_FUNC_MEMCMP): Use
8931 "char c = '\200';" rather than "char c = 0x80;" as the

8933 overflow on signed char hosts.
8935 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Prefer -qlanglvl=extc89
8936 to -qlanglvl=ansi. We don't want to disable extensions.

9049 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): If xmkmf returns

9190 zsh, disable GLOB_SUBST to avoid backslash handling problems.
9191 (trivial change)
9193 2004-06-04 Paul Eggert <eggert@cs.ucla.edu>
9195 * doc/autoconf.texi (File System Conventions): Warn about
9196 names like "aux". Problem reported by Eric Blake.
9198 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY (C)): Use division
9199 by zero instead of array size, so that we can use any arithmetic
9200 constant expression (instead of requiring an integer constant
9201 expression). This allows us to test expressions like DBL_MAX <
9202 LDBL_MAX, which didn't conform to the C standard using the old
9203 method.
9204 (AC_C_LONG_DOUBLE): Put back in the tests for LDBL_MAX and LDBL_EPSILON,
9205 now that we can do floating-point tests at compile time.
9207 2004-06-02 Paul Eggert <eggert@cs.ucla.edu>
9209 * lib/autoconf/c.m4 (AC_C_LONG_DOUBLE): Don't check LDBL_MAX
9210 and LDBL_EPSILON, as the resulting expression isn't an
9211 integer constant expression and violates the C standard.
9212 Problem reported by Nelson H. F. Beebe. Also, check
9213 for "L" suffix, and check that long double doesn't have
9214 worse range or precision than double, that mixed-mode
9215 arithmetic doesn't generate a diagnostic, that double
9216 constants fit in long double.
9218 2004-06-03 Kevin Ryde <user42@zip.com.au>
9220 * doc/autoconf.texi (Function Portability): Add notes on free(NULL),
9221 malloc(0) and realloc(NULL,size).
9223 * doc/autoconf.texi (Shell Substitutions): Spelling error reported by
9224 Bob Proulx.
9226 2004-05-31 Paul Eggert <eggert@cs.ucla.edu>
9228 * lib/autoconf/headers.m4 (HAVE_STDBOOL_H): Detect _Bool bug
9229 in HP aC++/ANSI C B3910B A.05.55 [Dec 04 2003]. Problem reported
9230 by Jim Meyering.
9232 2004-05-26 Paul Eggert <eggert@cs.ucla.edu>
9234 * doc/autoconf.texi (Limitations of Builtins): Mention that ! COMMAND
9235 can be rewritten using if-then-else. Suggested by Bruno Haible.
9237 2004-05-25 Paul Eggert <eggert@cs.ucla.edu>
9239 * doc/autoconf.texi (testsuite Scripts): Fix typo.
9240 Problem reported by Stepan Kasal.
9242 2004-05-24 Paul Eggert <eggert@cs.ucla.edu>
9244 * tests/Makefile.am (autoconfdir): Fix to match comment (trivial
9245 change). Patch reported by Ralf Wildenhues in
9246 <http://mail.gnu.org/archive/html/bug-autoconf/2004-05/msg00092.html>.
9248 * lib/autoconf/functions.m4 (AC_FUNC_MBRTOWC): Don't assume that a
9249 function F exists if the compiler and linker let you compile an
9250 expression like (F != 0). Recent versions of GCC optimize away
9251 the reference to F in that case, since every function address must
9252 be nonzero, so the link succeeds even if F does not exist.
9253 Problem reported by Manu in
9254 <http://mail.gnu.org/archive/html/bug-gnu-utils/2004-05/msg00060.html>.
9256 * doc/autoconf.texi (Systemology): Standardize on the spelling of
9257 "Unix". Many uses changed.
9258 (Limitations of Builtins): Explain better why the ! command isn't
9259 portable.
9261 2004-05-22 Alexandre Duret-Lutz <adl@gnu.org>
9263 * lib/autom4te.in (Automake-preselections): Preselect
9264 LT_SUPPORTED_TAG in lieu of AC_LIBTOOL_TAGS.
9266 2004-05-19 Kevin Ryde <user42@zip.com.au>
9268 * doc/autoconf.texi (Function Portability): Add strerror_r, cross
9269 referencing AC_FUNC_STRERROR_R.
9271 * doc/autoconf.texi (Particular Functions): In AC_FUNC_CLOSEDIR_VOID,
9272 note pessimistic assumption when cross compiling.
9274 2004-05-16 Paul Eggert <eggert@cs.ucla.edu>
9276 * doc/autoconf.texi (Limitations of Make): Note that BSD make
9277 (until 2004) invoked subcommands with sh -e, contra POSIX.
9278 Reported by Kevin Ryde.
9280 2004-05-10 Eric Sunshine <sunshine@sunshineco.com>
9282 * programs.m4 (_AC_PROG_GREP): Fixed bug where PATH argument handed to
9283 _AC_PATH_PROG_FEATURE_CHECK contained leading whitespace (i.e.
9284 " $PATH:/usr/xpg4/bin"). This resulted in bogus tests, such as
9285 `test -f " /usr/bin/grep"', which _always_ failed.
9286 (AC_PROG_SED): Ditto bogus PATH fix.
9287 * autoconf.texi (AC_PROG_GREP): Properly document that this macro
9288 requires that grep correctly supports _multiple_ `-e' options, rather
9289 than stating only that grep should accept `-e'.
9291 2004-05-03 Paul Eggert <eggert@cs.ucla.edu>
9293 Port to C99, which requires that 'exit' be declared.
9295 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Use AC_INCLUDES_DEFAULT
9296 to ensure that stdlib.h is included.
9297 * lib/autoconf/functions.m4 (_AC_LIBOBJ_ALLOCA, AC_FUNC_SETPGRP,
9298 AC_FUNC_STRTOD, AC_FUNC_SETVBUF_REVERSED, AC_FUNC_FORK, _AC_FUNC_FORK,
9299 _AC_FUNC_VFORK, AC_FUNC_WAIT3): Likewise.
9300 * lib/autoconf/specific.m4 (AC_SYS_RESTARTABLE_SYSCALLS): Likewise.
9301 * lib/autoconf/types.m4 (AC_TYPE_GETGROUPS): Likewise.
9302 * lib/autoconf/headers.m4 (AC_HEADER_STDC): Include <stdlib.h>
9303 when using 'exit' in a test; C99 requires that 'exit' be declared.
9305 2004-05-02 Paul Eggert <eggert@cs.ucla.edu>
9307 * doc/autoconf.texi (Particular Programs): AC_PROG_GREP
9308 now prefers 'grep' implementations that accept -e.
9309 (Limitations of Usual Tools): Describe problems of traditional
9310 egrep and fgrep with long input lines, and of traditional grep
9311 with -e.
9312 * lib/autoconf/programs.m4 (AC_PROG_GREP): Check for -e, too.
9313 (_AC_PROG_GREP): Assume 3rd arg is properly quoted for the shell.
9314 All callers changed. Append /usr/xpg4/bin to the PATH, for
9315 Solaris.
9316 (_AC_FEATURE_CHECK_LENGTH): Discard stderr, so we don't bother
9317 the user with complaints about multiple -e options.
9318 * tests/local.at (AC_STATE_SAVE): Use $GREP, not grep.
9319 Define it with AC_PROG_GREP.
9320 * configure.ac (AC_PROG_GREP): Add.
9321 * lib/freeze.mk (GREP): New macro.
9323 2004-05-02 Eric Sunshine <sunshine@sunshineco.com>
9325 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Consult $SHELL as
9326 a possible candidate only after all others fail, rather than
9327 consulting it first. This improves backward compatibility by
9328 better reflecting the way shell selection occurred in previous
9329 versions of Autoconf, and should help to avoid triggering latent
9330 problems in other packages, such as the one in Automake where zsh
9331 is not handled robustly:
9332 http://mail.gnu.org/archive/html/automake/2004-04/msg00095.html
9333 Although it is not Autoconf's responsibility to work around
9334 problems in Automake, it nevertheless makes sense to avoid
9335 introducing unnecessary incompatibilites.
9337 2004-04-22 Albert Chin-A-Young <china@thewrittenword.com>,
9338 Gary V. Vaughan <gary@gnu.org>
9340 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Don't guess
9341 how deeply nested we are when a suitable tool is found, set the
9342 ac_path_TOOL_found flag.
9343 (_AC_PATH_PROG_FEATURE_CHECK): Encapsulate knowledge of how deeply
9344 nested we are in this macro. Break out of all 3 nested loops if
9345 ac_path_TOOL_found is set.
9347 2004-04-21 Gary V. Vaughan <gary@gnu.org>
9349 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Break out
9350 of the _AS_PATH_WALK loop too if GNU flavor is found.
9352 2004-04-21 Alexandre Duret-Lutz <adl@gnu.org>
9354 * doc/autoconf.texi (Limitations of Make): Update documentation
9355 for `$<'. New entry `Long lines', based on a report from Simon
9356 Josefsson. Augment the documentation for SHELL = @SHELL@ with a
9357 paragraph about DJGPP, based on a mail from Richard Dawe.
9359 2004-04-20 Paul Eggert <eggert@twinsun.com>
9361 * tests/c.at (C keywords): Don't assume that GCC supports
9362 "restrict" and "inline", as sufficiently-old GCC versions do not
9363 (also, GCC configured to be in pedantic C89 mode does not).
9364 Problem reported by Sumit Pandya in:
9365 http://mail.gnu.org/archive/html/autoconf/2004-04/msg00092.html
9367 * lib/autoconf/c.m4 (_AC_PROG_CC_G, _AC_PROG_CXX_G): Don't
9368 consider -g to work if it generates warnings when plain compiles
9369 don't. Problem reported by Braden McDaniel in:
9370 http://mail.gnu.org/archive/html/autoconf-patches/2003-07/msg00014.html
9372 * doc/autoconf.texi (Slashes): New section, to document a problem
9373 reported by Jim Meyering in:
9374 http://mail.gnu.org/archive/html/bug-coreutils/2004-02/msg00060.html
9376 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Remove potential
9377 linker output files before linking, to work around IRIX 6 linker bug.
9378 Problem reported by Rainer Orth in:
9379 http://mail.gnu.org/archive/html/autoconf-patches/2004-02/msg00007.html
9381 2004-04-20 Gary V. Vaughan <gary@gnu.org>
9383 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Make the
9384 best tool so far counter rely on the tool path variable name to
9385 avoid checks for one tool being affected by the results of running
9386 the length check on a previous tool.
9388 * lib/autoconf/programs.m4 (_AC_PROG_GREP): Take an additional
9389 match expression argument, as different greps have different
9390 regular expression flavours.
9391 (AC_PROG_FGREP): Pass 'FGREP'. fgrep treats all match chars as
9392 literals.
9393 (AC_PROG_EGREP): Pass 'EGREP$'.
9394 (AC_PROG_GREP): Pass 'GREP$'.
9396 2004-04-20 Albert Chin-A-Young <china@thewrittenword.com>
9398 * lib/autoconf/programs.m4 (AC_PROG_GREP): Cache variable
9399 is `ac_cv_path_GREP', not `oc_cv_path_GREP'.
9401 2004-03-29 Paul Eggert <eggert@twinsun.com>
9403 * doc/autoconf.texi (Particular Headers, Particular Types, Generic
9404 Types, Specific Compiler Characteristics, System Services,
9405 Obsolete Macros): Use 'long int', 'short int', 'unsigned int'
9406 etc. consistently instead of 'long', 'short', 'unsigned' etc.
9407 * lib/autoconf/c.m4 (AC_LANG_INT_SAVE(C), AC_C_BIGENDIAN): Likewise.
9408 * lib/autoconf/functions.m4 (AC_FUNC_MMAP, AC_FUNC_SELECT_ARGTYPES):
9409 Likewise.
9410 * lib/autoconf/headers.m4 (AC_HEADER_SYS_WAIT): Likewise.
9411 * lib/autoconf/types.m4 (AC_TYPE_GETGROUPS, AC_TYPE_SIZE_T,
9412 AC_TYPE_OFF_T): Likewise.
9413 * tests/semantics.at (AC_CHECK_TYPES: backward compatibility):
9414 Likewise.
9416 * tests/foreign.at (Libtool): Create an empty aclocal.m4, to
9417 pacify libtool 1.5.2. Fix quoting problems in sed command.
9419 2004-03-28 Paul Eggert <eggert@twinsun.com>
9421 * doc/autoconf.texi (Particular Structures): AC_STRUCT_TIMEZONE
9422 now defines HAVE_DECL_TZNAME if it is declared, when
9423 HAVE_STRUCT_TM_TM_ZONE is not defined.
9424 * lib/autoconf/types.m4 (AC_STRUCT_TIMEZONE): Implement this.
9425 Do not assume atoi. Rely on HAVE_DECL_TZNAME when testing
9426 for HAVE_TZNAME.
9428 2004-03-28 Steven G. Johnson <stevenj@fftw.org>
9430 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Corrected
9431 superfluous backslashing of quotes (") in sed expressions;
9432 thanks to Paul Eggert.
9434 2004-03-26 Steven G. Johnson <stevenj@alum.mit.edu>
9436 * lib/autoconf/fortran.m4 (_AC_PROG_FC): new name of Intel
9437 Fortran compiler is ifort, also added pghpf; thanks to Nelson
9438 H. F. Beebe for the bug report.
9440 2004-03-26 Steven G. Johnson <stevenj@fftw.org>
9442 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): fix for
9443 quoted -cmdline argument in Portland Group compiler (bug
9444 reported by Jeffrey J. Barteet).
9446 2004-03-25 Kevin Ryde <user42@zip.com.au>
9448 * doc/autoconf.texi (Specifying Names): Move cross_compiling ovindex to
9449 (Run Time): ... here, where it's now mentioned.

9470 AC_CHECK_TOOLS.
9471 (Specifying Names): Document the reason for these future
9472 behavioral changes.
9473 * tests/mktests.sh: Do not generate tests for the
9474 new macros.
9475 * NEWS: Document these changes.
9477 * doc/autoconf.texi: Avoid macros with unbraced arguments,
9478 they make TeX hang up.

9483 * doc/autoconf.texi (Generic Compiler Characteristics): Document it.
9484 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Use long int rather than
9485 int; avoid "a `$1'" since this isn't grammatical if $1 begins with a
9486 vowel.
9487 (AC_CHECK_ALIGNOF): New macro.
9488 * tests/mktests.sh (ac_exclude_list): Exclude AC_CHECK_ALIGNOF.
9489 * tests/semantics.at (AC_CHECK_ALIGNOF): Add tests similar to
9490 those for sizeof.
9492 2004-03-03 Paul Eggert <eggert@twinsun.com>
9494 * bin/Makefile.am (edit): Don't use $< in a context where
9495 POSIX doesn't require support for it. Use $@.in instead.
9496 Problem reported by Anthony N. Frasso in
9497 <http://mail.gnu.org/archive/html/autoconf/2004-03/msg00008.html>.
9498 * bin/autoscan.in, bin/autoupdate.in: Add @configure_input@ comment.
9500 2004-02-23 Gary V. Vaughan <gary@gnu.org>
9502 * bin/autoreconf.in (autoreconf_current_directory): Recognize LT_INIT
9503 from the next generation of Libtool.

9526 AC_SUBST provides no portable way to escape literal newlines.
9528 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS): Ignore all
9529 flags of the form -lcrt*.o, not just -lcrt[01].o and -lcrtbegin.o.
9530 Darwin uses -lcrt2.o and there's little point to cataloging all
9531 the system variants. Partial fix reported by Andreas Waechter in:
9532 http://mail.gnu.org/archive/html/autoconf-patches/2004-02/msg00006.html
9533 for bug reported by Nelson H. F. Beebe in:

9546 refer to the correct file.
9547 * doc/autoconf.texi (AU_DEFUN): Describe more correctly
9548 the behavior of the third argument.
9549 * lib/autoconf/autoupdate.m4 (AU_DEFUN): Describe more
9550 correctly the behavior of the third argument. Document
9551 what the three macros that AU_DEFUN defines do. Fix

9556 Eric Sunshine <sunshine@sunshineco.com>
9557 Paul Eggert <eggert@twinsun.com>
9559 * lib/m4sugar/m4sh.m4 (M4SH-SANITIZE): New diversion.

9561 parameter. Expand _AS_SHELL_FN_SPY.
9562 (AS_INIT_WITH_SHELL_FN): Removed.
9563 (_AS_SHELL_FN_SPY): New macro.
9564 (AS_DETECT_REQUIRED, AS_DETECT_SUGGESTED): New

9607 * lib/autoconf/general.m4 (_AC_INIT_COPYRIGHT): Add 1992 thorugh
9608 2003 (except 1997) to the list of copyright years. This undoes

9622 (_AC_PATH_PROG_FEATURE_CHECK): Factor out the common core of
9623 _AC_PROG_GREP, and AC_PROG_SED.
9624 (_AC_FEATURE_CHECK_LENGTH): New helper macro for finding the
9625 longest input length accepted by a command.
9626 (AC_PROG_SED): Use it.
9627 * doc/autoconf.texi (Particular Programs): Document the changes.
9628 * NEWS: Updated.
9630 2004-01-27 Paul Eggert <eggert@twinsun.com>
9632 * bin/autoconf.as ($version): Update copyright from 2003 to 2004.
9633 * bin/autoheader.in, bin/autom4te.in, bin/autoreconf.in,
9634 bin/autoscan.in, bin/autoupdate.in, bin/ifnames.in: Likewise.
9635 * lib/autoconf/general.m4 (_AC_INIT_COPYRIGHT): Likewise.
9637 * Makefile.in, aclocal.m4, configure, bin/Makefile.in,
9638 bin/autoconf.in, config/Makefile.in, config/config.guess,
9639 config/config.sub, config/install-sh, config/mdate-sh,
9640 config/mkinstalldirs, config/texinfo.tex, doc/Makefile.in,

9650 tests/aclibs.at, tests/acspecific.at, tests/acstatus.at,
9651 tests/actypes.at: Regenerate and/or sync with original
9652 sources.
9654 2004-01-26 Paul Eggert <eggert@twinsun.com>
9656 * doc/autoconf.texi (Default Includes): Include <stdint.h> even if
9657 HAVE_INTTYPES_H is defined. This is needed on Tru64 5.1b with
9658 Compac C V6.5-207 (dtk), which defines uintmax_t in <stdint.h> but
9659 not <inttypes.h>. Problem reported by Tim Mooney in
9660 <http://mail.gnu.org/archive/html/bug-coreutils/2004-01/msg00147.html>.
9661 * lib/autoconf/headers.m4 (_AC_INCLUDES_DEFAULT_REQUIREMENTS):
9662 Likewise.
9664 * lib/autoconf/programs.m4 (AC_PROG_SED): Use diff, not sed;
9665 otherwise "make check" fails because it forbids cmp (I guess
9666 because cmp treats files as binary on DOS-like systems).
9668 * tests/mktests.sh: Update copyright date to 2004, since some tests
9669 have changed in 2004.
9671 2004-01-23 Gary V. Vaughan <gary@gnu.org>
9673 * lib/autoconf/programs.m4 (AC_PROG_SED): New macro to test for a
9674 non-truncating sed or gsed program in PATH.
9675 * tests/acprograms.at: Add it.
9676 * doc/autoconf.texi (Particular Programs): Document it.
9677 * NEWS: Updated.
9679 2004-01-15 Paul Eggert <eggert@twinsun.com>
9681 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Try -std, not -std1, since
9682 -std1 disables some useful extensions on Tru64. Problem reported
9683 by N. Lichtmaier in
9684 <http://mail.gnu.org/archive/html/autoconf/2004-01/msg00100.html>.
9686 2004-01-14 Paul Eggert <eggert@twinsun.com>
9688 * doc/autoconf.texi (Programming in M4sh): Document that
9689 AS_MKDIR_P succeeds if the destination is a symbolic link
9690 to an existing directory.
9691 (Limitations of Usual Tools): Note that mkdir -p might not
9692 succeed on symlinks to directories.
9694 2004-01-13 Paul Hilfinger <hilfinger@CS.Berkeley.EDU>
9696 * lib/autoconf/autoupdate.m4 (AU_DEFUN): Grammar fix in comment.
9697 * bin/autoheader.in: Grammar fix in message.
9698 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P):
9699 Test for dir before calling mkdir -p. (trivial changes)
9701 2004-01-13 Eric Blake <ebb9@byu.net>
9703 * doc/autoconf.texi (Obsolete Macros): In AC_TRY_COMPILE and
9704 AC_TRY_LINK, s/AC_LANG_SOURCE/AC_LANG_PROGRAM/. (trivial change)
9706 2004-01-10 Jim Meyering <jim@meyering.net>
9708 * doc/autoconf.texi (Running the Preprocessor): Correct grammar.
9710 2004-01-09 Paul Eggert <eggert@twinsun.com>
9712 * lib/autoconf/general.m4: Fix bug: AC_CHECK_SIZEOF evokes a warning
9713 with `autoconf -Wall,error'. Bug reported by Eric Blake in:
9714 http://mail.gnu.org/archive/html/autoconf-patches/2004-01/msg00000.html
9715 (_AC_COMPUTE_INT_COMPILE): Invoke _AC_COMPILE_IFELSE, not
9716 AC_COMPILE_IFELSE, since we now assume our caller invokes
9717 AC_LANG_COMPILER_REQUIRE, for symmetry with _AC_COMPUTE_INT_RUN.
9718 (_AC_COMPUTE_INT_RUN): Likewise, for _AC_RUN_IFELSE instead
9719 of AC_RUN_IFELSE; this avoids the warning mentioned above.
9720 (_AC_COMPUTE_INT): Invoke AC_LANG_COMPILER_REQUIRE.
9722 2004-01-07 Paul Eggert <eggert@twinsun.com>
9724 * lib/autoconf/general.m4 (_AC_LIBOBJS_NORMALIZE): Avoid \$ inside
9725 `"'...'"`, as it's confusing (and I suspect it may not work on
9726 some platforms). The code was incorrect anyway, as it assumed
9727 that \$ evaluated to itself in that context. Reported by
9728 Alexandre Duret-Lutz.
9730 2004-01-07 Alexandre Duret-Lutz <adl@gnu.org>
9732 * lib/autom4te.in (Automake-preselections): Preselect AC_LIBTOOL_TAGS
9733 and _LT_AC_TAGCONFIG.
9735 2004-01-06 Paul Eggert <eggert@twinsun.com>
9737 * doc/autoconf.texi (One Macro Call): Fix an incorrect
9738 example, and add more examples. Reported by Eric Sunshine.
9740 2004-01-05 Paul Eggert <eggert@twinsun.com>
9742 * doc/autoconf.texi (Limitations of Usual Tools):
9743 Remove warning against "rm -fr" introduced yesterday; it
9744 was a false alarm.
9746 * bin/Makefile.am (autoconf, autoheader, autom4te, autoreconf,
9747 autoscan, autoupdate, ifnames): Don't use chmod -w.
9748 * lib/Makefile.am (autom4te.cfg): Likewise.
9749 * doc/autoconf.texi (Limitations of Usual Tools): Warn against
9750 "chmod -w".
9752 2004-01-04 Paul Eggert <eggert@twinsun.com>
9753 Paolo Bonzini <bonzini@gnu.org>
9755 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Speed up sed scripts
9756 by doing lineno substitution only on lines containing "$LINENO".
9758 2004-01-04 Paul Eggert <eggert@twinsun.com>
9760 * lib/autoconf/general.m4 (AC_ARG_PROGRAM):
9761 Use "rm -f" to remove conftest.sed, not plain "rm".
9762 Bug reported by David Relson in
9763 <http://mail.gnu.org/archive/html/autoconf/2004-01/msg00011.html>.
9765 * Makefile.am (autom4te-update):
9766 Replace "rm -rf" and "rm -fr" with "rm -f -r", as POSIX requires.
9767 * Makefile.maint (my-distcheck, do-po-update): Likewise.
9768 * doc/autoconf.texi (Guidelines): Likewise.
9769 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Likewise.
9770 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): Likewise.
9771 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Likewise.
9772 * lib/autotest/general.m4 (AT_INIT): Likewise.
9773 * lib/m4sugar/m4sh.m4 (AS_TMPDIR): Likewise.
9774 * tests/Makefile.am (clean-local): Likewise.
9775 * tests/tortue.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS,
9776 srcdir): Likewise.
9777 * doc/autoconf.texi (Limitations of Usual Tools):
9778 Warn against "rm -fr".
9780 2004-01-03 Paul Eggert <eggert@twinsun.com>
9782 * doc/autoconf.texi (Limitations of Usual Tools): Mention that cc
9783 -c -o might not work. From a suggestion by Kevin Ryde.
9784 (C Compiler, Generating Sources, Limitations
9785 of Usual Tools, Limitations of Make, Making testsuite Scripts):
9786 Don't put '-o' after non-options, as POSIX doesn't allow this.
9787 Mention that cc's name might be gcc or c89 or whatever.
9789 2004-01-04 Kevin Ryde <user42@zip.com.au>
9791 * doc/autoconf.texi: Add various further index entries.
9793 2003-12-29 Paul Eggert <eggert@twinsun.com>
9795 * bin/autoreconf.in (autoreconf_current_directory):
9796 Fix typo: mkdir without umask arg.
9798 2003-12-27 Alexandre Duret-Lutz <adl@gnu.org>
9800 * doc/autoconf.texi (Limitations of Make) <Automatic rule rewriting>:
9801 Documents OSF1/Tru64 make behavior. Replace `VPATH = ../src' by
9802 `VPATH = ../pkg/src' in examples to make the OSF1/Tru64 make
9803 explanation clearer.
9805 2003-12-24 Andreas Schwab <schwab@suse.de>
9807 * doc/autoconf.texi (Default Includes): Fix misspelling of

9812 * configure.ac: Test if sh -n works.
9813 * configure: Regenerate.
9814 * tests/atlocal.in: Store the result here.
9815 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Extracted from
9816 tools.at, looking in atlocal's ac_cv_sh_n_works instead
9817 of explicitly testing.
9818 (AT_CHECK_PERL_SYNTAX): Moved from tools.at.
9819 (AT_CHECK_AUTOCONF): Test for the configure script syntax.
9820 * tests/tools.at (Syntax of the shell scripts): Simplify
9821 using AT_CHECK_SHELL_SYNTAX.

9834 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE):
9835 Extracted from AS_SHELL_SANITIZE.
9836 (_AS_SHELL_FN_WORK, AS_INIT_WITH_SHELL_FN): New
9837 macros.
9838 (AS_SHELL_SANITIZE): Move reinvocation code from
9839 _AS_LINENO_WORKS, use it to find out if shell
9840 functions work.
9841 (_AS_LINENO_WORKS): Don't find another shell if $LINENO
9842 does not work.
9843 (AS_INIT): Pass parameter down to AS_SHELL_SANITIZE.
9844 (AS_REQUIRE_SHELL_FN): Test that AS_INIT_WITH_SHELL_FN

9858 them on the fly.
9860 2003-11-24 Akim Demaille <akim@epita.fr>
9862 * doc/autoconf.texi (Particular Programs): AC_PROG_LEX can

9905 * doc/autoconf.texi (Using System Type): Revise, showing $host rather
9906 than $target since the latter is not usual, add guidelines on when to
9907 use or not use the system type.
9909 2003-11-12 Derek Price <derek@ximbiot.com>
9911 * doc/autoconf.texi (Limitations of Usual Tools): Fix what looks like a

9931 * lib/autoconf/status.m4 (_AC_SRCPATHS): Fix use of AS_SET_CATFILE

9940 2003-11-05 Kevin Ryde <user42@zip.com.au>

10097 2003-10-08 Gary V. Vaughan <gary@gnu.org>
10099 * lib/autoconf/general.m4 (AC_CONFIG_MACRO_DIR): Stub out a macro
10100 that future autopoint/aclocal/automake/autoreconf will be able
10101 to trace to find where to install local m4 macros.
10102 * doc/autoconf.texi (Input): Document it.
10103 * NEWS: Updated.
10105 2003-10-06 Gary V. Vaughan <gary@gnu.org>
10107 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS): Add
10108 -lcrtbegin.o to list of ignored flags and fix underquoting of
10109 -lcrt[01].o.
10111 2003-10-04 Steven G. Johnson <stevenj@ab-initio.mit.edu>
10113 * lib/autoconf/fortran.m4 (_AC_PROG_FC_G): Use language-specific
10114 cache variable instead of $G77 to decide whether to include -O2,
10115 since $G77 is specific to Fortran 77.
10117 2003-10-03 Steven G. Johnson <stevenj@alum.mit.edu>
10119 * lib/autoconf/fortran.m4 (AC_FC_FREEFORM): Support Absoft "-f
10120 free" flag. Re-order flags tested into rough order of popularity.
10122 2003-10-03 Steven G. Johnson <stevenj@alum.mit.edu>
10124 * lib/autoconf/fortran.m4 (AC_PROG_FC): Reverse the order of the
10125 arguments so that it can be used with syntax identical to
10126 AC_PROG_F77, and so that we can more easily decide to
10127 remove/deprecate the DIALECT optional argument in the future if it
10128 proves troublesome.
10129 (AC_FC_FREEFORM): Exit 77 upon failure to fix test suite for
10130 non-freeform-supporting compilers. Document freeform flags.
10132 2003-10-03 Akim Demaille <akim@epita.fr>
10134 * configure.ac: Look for emacs, not macs.
10135 Reported by Eric Sunshine.
10137 2003-10-03 Akim Demaille <akim@epita.fr>
10139 * lib/autom4te.in (Autoreconf-preselections): Trace AC_CONFIG_AUX_DIR.
10140 * bin/autoreconf.in (autoreconf_current_directory): Create the
10141 AUX_DIR if needed, for sake of automake --add-missing etc.
10142 Suggested by Alexandre Duret-Lutz.
10144 2003-10-03 Akim Demaille <akim@epita.fr>
10146 * configure.ac: Quotation and formatting changes.
10147 (EMACS): Don't set it if it is not recent enough to support
10148 autoconf-mode.el.
10149 From Eric Sunshine.
10151 2003-10-02 Akim Demaille <akim@epita.fr>

10167 * lib/Autom4te/XFile.pm: Use Errno.
10168 (lock): Ignore ENOLCK errors. Problem reported Andreas Schwab in
10169 <http://mail.gnu.org/archive/html/bug-autoconf/2003-09/msg00141.html>.
10171 2003-09-30 Akim Demaille <akim@epita.fr>
10173 * config/announce-gen (&print_news_deltas): Extracted from...
10174 (&print_changelog_deltas): here.
10175 (&news_file): Rename as...
10176 (@news_file): this.
10178 2003-09-30 Nicolas Joly <njoly@pasteur.fr>
10180 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Remove files which might
10181 have been created when invoking the compiler.
10182 * tests/fortran.at (GNU Fortran 77): Quote $G77.
10184 2003-09-29 Akim Demaille <akim@epita.fr>
10186 Version 2.57e.
10188 * config/mkinstalldirs: Upgrade.

10192 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Set DUALCASE=1, for MKS sh.
10193 Problem reported by Lars J. Aas in
10194 <http://mail.gnu.org/archive/html/autoconf/2003-07/msg00042.html>.
10195 (_AS_MKDIR_P_PREPARE): Change "rm -fr ./-p" to the more-conservative
10196 "test -d ./-p && rmdir ./-p". Suggested by Andreas Schwab in:
10197 http://mail.gnu.org/archive/html/autoconf-patches/2003-09/msg00039.html
10199 2003-09-26 Akim Demaille <akim@epita.fr>
10201 * lib/autoconf/status.m4 (_AC_OUTPUT_COMMANDS): Make sure the
10202 directory for AC_CONFIG_COMMANDS' first argument exists.
10203 This makes valid the invocation of _AC_SRCPATH that follows.
10204 Reported by Eric Sunshine.
10205 * doc/autoconf.texi (Configuration Commands): Adjust.
10207 2003-09-26 Akim Demaille <akim@epita.fr>
10209 * bin/autoscan.in (Autom4te::FileUtils): Use it for find_file.
10210 Reported by Ralf Corsepius.
10212 2003-09-26 Akim Demaille <akim@epita.fr>
10214 * lib/autoconf/general.m4 (AC_HELP_STRING): Don't overquote the
10215 arguments.
10216 Actually, use AU_ALIAS.
10217 From Bruno Haible.
10219 2003-09-26 Paul Eggert <eggert@twinsun.com>
10221 * lib/m4sugar/m4sh.m4 (_AS_MKDIR_P_PREPARE): If mkdir -p . fails,
10222 rm -fr ./-p to remove junk left behind on NextStep and OpenStep.
10223 Problem reported by Eric Sunshine in:
10224 http://mail.gnu.org/archive/html/autoconf-patches/2002-12/msg00014.html
10226 2003-09-26 Akim Demaille <akim@epita.fr>
10228 The test suite are sometimes assigning timings incorrectly.
10229 Reported by Henk Krus.
10230 Diagnosed by Nicolas Joly.
10232 * lib/autotest/general.m4 (AT_CLEANUP): Rename AT_help as
10233 AT_help_all.
10234 Instead of making AT_help a sequence of assignments to grow
10235 $at_help_all, just make AT_help_all be the growing contents of
10236 $at_help_all, and make a single assignment in...
10237 (AT_INIT): here.
10238 (at_times_skip): Flip the meaning and rename as...
10239 (at_times_p): this.
10240 (AT_INIT): When summarizing the test that ran, remove
10241 $at_times_file after use, and check it is present before trying to
10242 use it.
10244 2003-09-25 Akim Demaille <akim@epita.fr>
10246 Version 2.57d.
10248 * bin/Makefile.am (edit): Handle '@configure_input@'.
10249 (autoconf, autoheader, autom4te, autoreconf, autoscan, autoupdate)
10250 (ifnames): chmod -w.
10251 * tests/wrapper.as (AUTOCONF, AUTOM4TE, ): Point to tests/
10252 executables, not bin/ executables! Otherwise all the magic needed
10253 to find non installed files is turned off. This caused a failure
10254 of test 40 and 41 that ran aclocal 1.8 which in turn ran autom4te
10255 as found in its environment (sent by tests/autoreconf): pointing
10256 to bin/autom4te that could not find its files.
10257 * tests/mktests.sh: Force the replacement of generated files, for
10258 the sake of "mv" program that are interactive when overwriting a
10259 -w file.
10260 * config/install-sh: Upgrade from CVS Automake.
10262 2003-09-23 Paul Eggert <eggert@twinsun.com>

10265 versus test -L issues.
10267 2003-09-23 Daniel Jacobowitz <drow@mvista.com> and
10268 Paul Eggert <eggert@twinsun.com>
10270 Trivial change to support GCC's configuration procedure.
10271 * lib/autoconf/c.m4 (AC_PROG_CPP_WERROR): New macro.
10272 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): Don't warn
10273 about inconsistency if the preprocessor is set to give errors for
10274 any warning.
10275 * doc/autoconf.texi (C Compiler Characteristics): Document this.
10277 2003-09-13 Alexandre Duret-Lutz <adl@gnu.org>
10279 * Makefile.am (autom4te-update, autom4te_files): Fetch Struct.pm
10280 and XFile.pm from Automake.

10290 * lib/Autom4te/Channels.pm, lib/Autom4te/Configure_ac.pm: Update
10291 from masters.
10293 2003-09-12 Akim Demaille <akim@epita.fr>
10295 * doc/autoconf.texi (Header Portability): Promote linux/types.h,
10296 not asm/types.h.
10298 2003-09-11 Akim Demaille <akim@epita.fr>
10300 * doc/autoconf.texi (Header Portability): linux/random.h.
10301 From Peter Hendrickson.
10303 2003-09-10 Akim Demaille <akim@epita.fr>
10305 * tests/mktests.sh (au_exclude_egrep): Make it harder to be
10306 willing to edit the output files.
10308 2003-09-10 Akim Demaille <akim@epita.fr>
10310 * tests/fortran.at (GNU Fortran 77): Also exercise AC_FC_SRCEXT
10311 and AC_FC_FREEFORM.
10312 * tests/mktests.sh: Skip AC_FC_SRCEXT.
10313 * lib/autoconf/fortran.m4 (AC_FC_SRCEXT, AC_FC_FREEFORM): Likewise.
10315 2003-09-09 Akim Demaille <akim@epita.fr>

10324 trailing files.
10326 2003-09-07 Paul Eggert <eggert@twinsun.com>
10328 * lib/autoconf/specific.m4 (AC_SYS_RESTARTABLE_SYSCALLS):
10329 Improve the accuracy of the wording about obsolescence.
10330 From a suggestion by Ian Lance Taylor in
10331 <http://mail.gnu.org/archive/html/autoconf/2003-09/msg00044.html>.
10333 2003-09-05 Paul Eggert <eggert@twinsun.com>
10335 * lib/autoconf/fortran.m4 (AC_FC_FREEFORM): Try -ffree-form too,
10336 for the benefit of g77 3.2. Fix suggested by Steven G. Johnson.
10338 2003-09-04 Akim Demaille <akim@epita.fr>
10340 * tests/mktests.sh (ac_exclude_list): Fix the filtering of
10341 AC_FUNC_WAIT3.
10343 2003-09-04 Akim Demaille <akim@epita.fr>
10345 * bin/autom4te.in: Use &fatal where more appropriate than &error.
10346 (freeze): When exiting, use $exit_code.
10347 * lib/autoconf/fortran.m4: Comment changes.
10349 2003-09-04 Akim Demaille <akim@epita.fr>
10351 * tests/mktests.sh (ac_exclude_list): Add AC_FC_FUNC.
10353 2003-09-02 Steven G. Johnson <stevenj@alum.mit.edu>
10355 Add support for newer Fortran dialects. The F77 interface is
10356 unchanged, and continues to support Fortran 77. New FC macros
10357 correspond to all the old F77 macros, with output variables FC,
10358 FCFLAGS, and FCLIBS. AC_PROG_FC defaults to picking the newest
10359 available dialect, but older dialects can be specified. There are
10360 new macros AC_FC_SRCEXT to set the source extension, and
10361 AC_FC_FREEFORM to accept free-form source files.
10363 * lib/autoconf/c.m4 (_AC_LANG_PREFIX(C), _AC_LANG_PREFIX(C++)):
10364 New macros.
10365 (AC_LANG_PROGRAM(C)): Invoke _AC_LANG_PROGRAM_C_FC_HOOKS if defined.
10366 * lib/autoconf/fortran.m4 (AC_LANG(Fortran), _AC_FORTRAN_ASSERT,
10367 _AC_LANG_ABBREV(Fortran), _AC_LANG_PREFIX(Fortran 77),
10368 _AC_LANG_PREFIX(Fortran), _AC_FC, AC_LANG_SOURCE(Fortran),

10376 _AC_FC_WRAPPERS, AC_FC_WRAPPERS, _AC_FC_FUNC, AC_FC_FUNC,
10377 AC_FC_SRCEXT, AC_FC_FREEFORM):
10378 New macros.
10379 (AC_PROG_F77, AC_PROG_F77_C_O, AC_F77_LIBRARY_LDFLAGS,
10380 AC_F77_DUMMY_MAIN, AC_F77_MAIN, _AC_F77_NAME_MANGLING,
10381 AC_F77_NAME_MANGLING, AC_F77_WRAPPERS, AC_F77_FUNC):
10382 Rewrite in terms of the above.
10383 (_AC_PROG_F77_G, _AC_PROG_F77_V_OUTPUT, _AC_PROG_F77_V): Remove.
10384 * lib/autoconf/lang.m4 (_AC_LANG_PREFIX): New macro.
10385 * tests/acfortran.at: Test AC_FC_FREEFORM, AC_FC_FUNC,
10386 AC_FC_MAIN, AC_FC_SRCEXT, AC_FC_WRAPPERS, AC_PROG_FC_C_O.
10388 2003-09-02 Paul Eggert <eggert@twinsun.com>
10390 * doc/autoconf.texi (Limitations of Usual Tools, Limitations of Make):
10391 Document problems with timestamp resolution that 'make', 'cp -p', and
10392 'touch -r' have.
10394 2003-08-27 Akim Demaille <akim@epita.fr>
10396 * tests/m4sugar.at (cross_warning): Make sure to enable the
10397 output, so that we can track spurious m4sugar output.
10398 * tests/local.at: Require 2.57.
10399 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): Don't m4_default the arguments that
10400 are defaulted by AT_CHECK anyway.
10401 Use AT_CHECK_AUTOM4TE.
10402 * lib/m4sugar/m4sugar.m4: There should be no output at all: add a
10403 missing dnl.
10405 2003-08-27 Akim Demaille <akim@epita.fr>
10407 * bin/autoheader.in: Issue the "Using auxiliary..." message only
10408 when -Wobsolete is set.
10409 Set it on by default.
10410 Suggested by Klee Dienes.
10412 2003-08-27 Akim Demaille <akim@epita.fr>
10414 * doc/autoconf.texi (AC_FUNC_FSEEKO, AC_SYS_LARGEFILE): More

10421 after AC_OUTPUT.
10423 2003-08-25 Akim Demaille <akim@epita.fr>
10425 * config/announce-gen, GNUmakefile, Makefile.maint: Update from

10454 2003-08-22 Akim Demaille <akim@epita.fr>
10456 Output stack traces in warnings.
10458 * lib/m4sugar/m4sugar.m4 (_m4_warn): New.
10459 Replace the former...
10460 (m4_warn): Pass the call stack to _m4_warn.
10461 * bin/autom4te.in: Adjust to output the call stack.
10462 * tests/m4sugar.at (m4@&t@_warn): Adjust.
10464 2003-08-22 Akim Demaille <akim@epita.fr>
10466 * lib/Autom4te/Request.pm, lib/Autom4te/C4che.pm: New.
10467 * bin/autom4te.in: Adjust.
10469 2003-08-21 Akim Demaille <akim@epita.fr>
10471 * lib/Autom4te/General.pm (&file_name_is_absolute): Remove.
10472 (&verbose): Remove.
10473 (&getopt): Adjust the note and verb channels, depending upon
10474 --verbose.
10475 * bin/autoheader.in, bin/autom4te.in, bin/autoscan.in,
10476 * bin/autoupdate.in: Adjust.
10477 Use &verb, not &verbose.
10479 2003-08-21 Akim Demaille <akim@epita.fr>
10481 * bin/autoheader.in (&parse_args): Use &parse_warnings and
10482 &parse_WARNINGS.
10483 ($help): Use Autom4te::ChannelDefs::usage.
10484 * bin/autoscan.in: Use Autom4te::ChannelDefs.
10485 * lib/Autom4te/General.pm: Don't export error: you don't own it.
10487 2003-08-21 Akim Demaille <akim@epita.fr>
10489 First stab at preserving warnings between calls to autom4te,
10490 including when the cache is used.
10492 There are still several issues: (i) there are too many runs of m4
10493 (one for include, one for warnings, and some more), (ii) warnings
10494 spreading on several lines are not handled gracefully, (iii) the
10495 code meant to have the call stack display for errors does not work
10496 (its handling should move from m4 to autom4te).
10498 * bin/autom4te.in Autom4te::Channels, Autom4te::ChannelDefs):
10499 Use them.
10500 (@preselect): Add m4_warn.
10501 ($exit_status): Remove, use $exit_code.
10502 ($help): Use Autom4te::ChannelDefs::usage.
10503 (&handle_m4): No longer define the m4_warnings.
10504 At each run, extract and report the warnings.
10505 Always cache the result, including if the exit status is on
10506 failure, since if nothing changes, we should result in the same
10507 failure, hence we can use the cache.
10508 * lib/m4sugar/m4sugar.m4 (m4_warning_ifelse, _m4_warning_ifelse)
10509 (_m4_warning_error_ifelse, __m4_warning_error_ifelse, _m4_warn):
10510 Remove.
10511 (m4_warn): Redefine as a do-nothing: it is its invocation that
10512 matters, as warnings are now reported via traces.
10513 * lib/autoconf/general.m4 (AC_DIAGNOSE): Don't make it a copy of
10514 the contents of m4_warn: make it _call_ m4_warn, so that tracing
10515 the latter reveals calls to the former.
10517 Adjust the tests.
10519 * tests/m4sugar.at (m4@&t@_warn): Use existing warning categories.
10521 2003-08-21 Akim Demaille <akim@epita.fr>
10523 * bin/autoreconf.pm (Autom4te::Channels, Autom4te::ChannelDefs):
10524 Use them.
10526 2003-08-21 Akim Demaille <akim@epita.fr>
10528 * lib/Autom4te/FileUtils.pm (&find_file): Walk the @include in
10529 forward order.
10530 * lib/Autom4te/ChannelDefs.pm: Doc typos.
10531 (&parse_warnings): Accept a list of warning requests.
10532 (&usage): Return a string, not a side effect.
10533 (cross): New warning category.
10535 2003-08-21 Akim Demaille <akim@epita.fr>
10537 * lib/Autom4te/Configure_ac.pm (&find_configure_ac)
10538 (&require_configure_ac): Accept an optional directory argument.
10539 ($configure_ac): Remove.
10540 * lib/Autom4te/General.pm (&find_configure_ac, &canonfile)
10541 (&catfile): Remove.
10542 * bin/autoheader.in, bin/autoreconf.in, bin/autoupdate.in,
10543 * bin/autoscan.in: Adjust.
10545 2003-08-20 Akim Demaille <akim@epita.fr>
10547 * bin/autoheader.in: Remove duplicate 'use Autom4te::FileUtils'.
10548 Reported by Alexandre Duret-Lutz.
10550 2003-08-20 Akim Demaille <akim@epita.fr>
10552 * bin/autoupdate.in, bin/autoheader.in, bin/autoreconf.in,
10553 * bin/autom4te: Adjust.
10554 In particular, be Autoconf tools are really silent when properly
10555 working, bind the verbosity of the 'note' channel to $verbose.
10556 * lib/Autom4te/General.pm (&find_file, &mtime, &update_file)
10557 (&xsystem, &contents): Remove, since they are exported by...

10559 More perldoc.
10560 * lib/Autom4te/General.pm (&up_to_date_p): Move to...
10561 * lib/Autom4te/FileUtils.pm: here.
10563 2003-08-20 Akim Demaille <akim@epita.fr>
10565 * lib/Autom4te/Channels.pm, lib/Autom4te/ChannelDefs.pm
10566 * lib/Autom4te/Configure_ac.pm, lib/Autom4te/FileUtils.pm: New,

10627 2003-08-12 Derek Price <derek@ximbiot.com>
10629 * lib/autotest/general.m4 (AT_CHECK): Use new _AT_CHECK API.
10630 (AT_CHECK_NOESCAPE): Move core functionality to...
10631 (_AT_CHECK): ...this new macro.
10633 2003-08-07 Derek Price <derek@ximbiot.com>
10635 * lib/autotest/general.m4 (AT_CHECK): Move core functionality...
10636 (AT_CHECK_NOESCAPE): ...to this new macro.
10638 2003-07-31 Paul Eggert <eggert@twinsun.com>
10640 * lib/m4sugar/m4sh.m4 (_AS_UNSET_PREPARE): Work around a bug
10641 in Bash 2.01. Problem reported by Brian Gough in
10642 <http://mail.gnu.org/archive/html/bug-autoconf/2003-07/msg00106.html>.
10644 2003-07-25 John W. Eaton <jwe@bevo.che.wisc.edu>
10646 * lib/autoconf/fortran.m4 (AC_F77_LIBRARY_LDFLAGS): Also ignore
10647 -lcrt1.o, for OS X. (trivial change)
10649 2003-07-07 Paul Eggert <eggert@twinsun.com>
10651 * lib/autoconf/c.m4 (AC_C_INLINE): Wrap the '#define inline ...'
10652 inside '#ifndef __cplusplus'. Problem reported by
10653 Bob Friesenhahn.
10655 2003-07-06 Bill Clarke <llib@computer.org>
10657 * lib/autoconf/functions.m4 (AC_FUNC_MMAP): Cast pointer to
10658 'long', not 'int', for benefit of Sun's recent C++ compilers
10659 (trivial change). See:
10660 http://mail.gnu.org/archive/html/autoconf-patches/2003-07/msg00007.html
10661 (This really should be 'intptr_t', not 'long', but that would
10662 take more work.)
10664 2003-06-25 Akim Demaille <akim@epita.fr>
10666 * lib/Makefile.am (autom4te.cfg): Make it read only.
10667 Depend on Makefile since it contains substitutions.
10668 From Paolo Bonzini.
10669 * lib/autom4te.in (args): Add local.at? for Autotest args.
10670 This change was made on autom4te.cfg which is generated.
10671 Reported by Raja R. Harinath.
10673 2003-06-25 Akim Demaille <akim@epita.fr>
10675 * doc/autoconf.texi (Header Portability): sys/mount.h.
10676 From Gareth McCaughan.
10678 2003-06-23 Akim Demaille <akim@epita.fr>
10680 * lib/autotest/general.m4 (AT_INIT): Report a single config.log,
10681 not all of them. This fixes 1. the fact that when testing
10682 Autoconf there are many many config.log, 2. the incorrect use of
10683 top_srcdir to find config.log.
10684 Don't mix the detailed output of failed test with the summary of
10685 failures. Rather, append detailed log afterwards.
10687 2003-06-23 Akim Demaille <akim@epita.fr>
10689 * tests/local.at (AT_CHECK_CONFIGURE): Adjust to the verbose being
10690 always run: output config.log on $at_group_log.
10692 2003-06-23 Akim Demaille <akim@epita.fr>
10694 * tests/torture.at (#define header templates): Don't use quotes in
10695 C++ comments as it puzzles Emacs' sh font-lock-mode.
10697 2003-06-23 Akim Demaille <akim@epita.fr>
10699 * tests/mktests.sh (au_exclude_egrep): Fix output copyright notice.
10700 * lib/autom4te.cfg (args): Add local.at? for Autotest args.
10701 * tests/atspecific.m4: Rename as...
10702 * tests/local.at: This.
10703 * tests/suite.at: Move the globals into...
10704 * tests/local.at: here.
10705 * tests/Makefile.am: Adjust.
10706 * doc/autoconf.texi (testsuite Scripts): Adjust.

10710 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Extend test program to get an
10711 error from OSF 4.0 Compaq cc in its default almost-ANSI mode, thereby
10712 ensuring we add -std1 for full-ANSI.
10714 * doc/autoconf.texi (hdrindex): New macro.
10715 Add index entries for portability of various standard header files.
10717 2003-06-20 Akim Demaille <akim@epita.fr>
10719 * configure.ac: Bump to 2.57b.
10721 2003-06-20 Akim Demaille <akim@epita.fr>
10723 Version 2.57a.
10725 2003-06-20 Akim Demaille <akim@epita.fr>
10727 * bin/autom4te.in: Don't rely on $HOME being defined.
10728 Reported by Marc Espie as PR/233.
10730 2003-06-20 Akim Demaille <akim@epita.fr>
10732 * lib/autotest/general.m4: Use at_times_file only if used.
10733 From Nicolas Joly.
10735 2003-06-20 Akim Demaille <akim@epita.fr>
10737 * config/config.guess, config/config.sub, config/elisp-comp,
10738 * config/install-sh, config/mkinstalldirs, doc/standards.texi:
10739 Update from masters.
10741 2003-06-11 Paolo Bonzini <bonzini@gnu.org>
10743 * doc/autoconf.texi (Writing testsuite.at): Document AT_XFAIL_IF
10744 * lib/autotest/general.m4 (AT_XFAIL_IF): New macro.
10745 (TEST_SCRIPT): New diversion.
10746 (AT_SETUP): Divert output to TEST_SCRIPT and move some code...
10747 (AT_CLEANUP): ...to here. Undivert TEST_SCRIPT.
10748 (AT_INIT): Support for expected failures.
10750 2003-06-02 Akim Demaille <akim@epita.fr>
10752 * bin/autom4te.in, bin/autoscan.in, bin/autoheader.in: White space
10753 changes.
10754 * lib/Autom4te/General.pm (&backname): Remove, no longer used by
10755 Autoconf nor Automake.
10756 (&contents): New, from Automake.
10757 PODify.
10759 2003-05-28 Paul Eggert <eggert@twinsun.com>
10761 * NEWS, doc/autoconf.texi (Particular Functions),
10762 lib/autoconf/functions.m4 (AC_FUNC_MKTIME): Check that mktime
10763 is the inverse of localtime.
10765 2003-05-25 Alexandre Duret-Lutz <adl@gnu.org>
10767 * lib/Autom4te/General.pm (END): Print diagnostics to STDERR.
10768 (handle_exec_errors): New function. Work around $! being
10769 altered by WEXITSTATUS.
10770 (xqx, xsystem): Use handle_exec_errors.
10772 2003-05-23 Alexandre Duret-Lutz <adl@gnu.org>
10774 * lib/Autom4te/General.pm (END): Rewrite exit code processing.
10775 Do not call `_exit()', simply modify `$?'.
10776 (xsystem): Reset $! before running system, and check it afterward.
10777 * tests/tools.at (autoupdating AC_PREREQ): Expect exit status
10778 63 for version mismatches.
10780 2003-05-23 Akim Demaille <akim@epita.fr>
10782 * lib/autoconf/status.m4: Prefer "TAB-SP" to "SP-TAB", because of
10783 Emacs' dangerous whitespace.el behavior (smashing "useless" spaces in
10784 the middle of a line).
10785 * lib/m4sugar/m4sugar.m4: Likewise.
10786 Remove useless spaces in comments.
10788 2003-05-23 Akim Demaille <akim@epita.fr>
10790 * lib/m4sugar/m4sugar.m4 (m4_version_prereq): Failure causes an
10791 exit 63, so that we (or Automake's "missing") can tell the
10792 difference with a plain failure.
10793 * doc/autoconf.texi (Notices): Adjust.
10795 2003-05-23 Akim Demaille <akim@epita.fr>
10797 * Makefile.am, bin/Makefile.am, config/Makefile.am,
10798 * doc/Makefile.am, lib/autoconf/Makefile.am, tests/Makefile.am:
10799 White spaces cleanup.
10801 2003-05-22 Jim Meyering <jim@meyering.net>
10802 Paul Eggert <eggert@twinsun.com>
10804 * lib/autoconf/c.m4 (_AC_PROG_CXX_EXIT_DECLARATION):
10805 Remove `#include <stdlib.h>' from the list; we should never
10806 make confdefs.h include <stdlib.h> or <cstdlib>, because the
10807 resulting namespace pollution would cause other tests to fail.
10808 Configure scripts run with some older versions of g++ and HP's
10809 aCC would fail due to such an #include. Problems reported by
10810 Matthew Mueller in <http://bugs.debian.org/120704> and by
10811 Keith Bostic in
10812 <http://mail.gnu.org/archive/html/autoconf/2003-05/msg00063.html>.
10813 In the test, use the test declaration before including <stdlib.h>,
10814 as that's closer to how it'll be used.
10816 2003-05-23 Akim Demaille <akim@epita.fr>
10818 * doc/autoconf.texi (Header Portability): ucred.h.
10819 From Ian Redfern.
10821 2003-05-22 Paolo Bonzini <bonzini@gnu.org>
10823 Overhaul Autotest's logging: generate separate log files
10824 in testsuite.dir/NNN/testsuite.log, and append them to
10825 testsuite.log instead of re-running the test verbosely.
10827 * lib/autotest/general.m4 (AT_INIT): Use a single redirected
10828 file descriptor, write 0 to at_status_file instead of setting
10829 at_status=0, initialize some new variables (at_status_file,
10830 at_group_log, at_suite_log, at_tee_pipe). Remove the cruft
10831 to rerun the tests, instead append the at_group_log to the
10832 at_suite_log when a test fails.
10833 (AT_SETUP): pipe the test case's output into at_tee_pipe,
10834 with the AS_MESSAGE_LOG_FD redirected to stdout.
10835 (AT_CLEANUP): save the output status in $at_status_file
10836 and restore it, redirect the AS_MESSAGE_LOG_FD back to
10837 its original place.
10838 (AT_CHECK): since tests are run with a redirected stdout,
10839 and used to be re-run in verbose mode, turn some $at_verbose
10840 into echo, and don't redirect the output of testing stdout
10841 and stderr.
10843 * lib/autotest/autoconf.texi (testsuite Scripts): Update
10844 the name of the debugging directory and information about
10845 its contents.
10847 2003-05-22 Paolo Bonzini <bonzini@gnu.org>
10849 * lib/m4sugar/m4sh.m4 (AS_REQUIRE): Actually use the 2nd
10850 parameter.
10852 2003-05-22 Akim Demaille <akim@epita.fr>
10854 * lib/autoconf/autotest.m4, lib/autoconf/autoupdate.m4
10855 * lib/autoconf/fortran.m4 lib/autoconf/general.m4
10856 * lib/autoconf/headers.m4 lib/autoconf/oldnames.m4

10872 Whitespace clean up.
10873 Suggested by Jim Meyering.
10875 2003-05-22 Akim Demaille <akim@epita.fr>
10877 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Restore smashed
10878 ' \t' as '\t ' so that Emacs' whitespace.el keep it.
10879 Reported by Jim Meyering.
10881 2003-05-22 Akim Demaille <akim@epita.fr>
10883 * doc/autoconf.texi: Replace AC_HELP_STRING AS_HELP_STRING.
10884 Add AC_HELP_STRING to the obsolete macros section.
10885 Typos.
10886 Use '@.' for sentences that ended in a capital letter.
10887 From Art Haas.

10905 2003-05-19 Paul Eggert <eggert@twinsun.com>
10907 * ChangeLog, ChangeLog.2, THANKS, lib/m4sugar/m4sugar.m4:
10908 Remove non-ASCII characters.
10910 2003-05-18 Paolo Bonzini <bonzini@gnu.org>
10912 * tests/semantics.at (AC_SEARCH_LIBS): New test.
10913 * tests/semantics.at (AC_CHECK_HEADERS_OLD,
10914 AC_CHECK_HEADERS_NEW): New tests.
10916 2003-05-17 Akim Demaille <akim@epita.fr>
10918 * lib/autoconf/functions.m4: Use the default includes so that
10919 memcmp be declared before being tested.
10920 Reported by Sander Niemeijer.
10921 (AC_FUNC_ERROR_AT_LINE, AC_FUNC_GETGROUPS, AC_FUNC_STRNLEN): Likewise.
10922 * doc/autoconf.texi (Default Includes): Document
10923 AC_INCLUDES_DEFAULT.
10925 2003-05-17 Akim Demaille <akim@epita.fr>
10927 * lib/autoconf/specific.m4: Include signal.h and unistd.h.
10928 * doc/autoconf.texi (Obsolete Macros): Adjust.
10929 Reported by Werner LEMBERG and Debian Bug 190886.
10931 2003-05-16 Akim Demaille <akim@epita.fr>
10933 * lib/m4sugar/m4sh.m4 (_AS_UNSET_PREPARE): s/FOO/as_foo/ to avoid
10934 user name space clashes.
10935 Reported by Bruno Haible.
10937 2003-05-16 Akim Demaille <akim@epita.fr>
10939 * bin/autoheader.in, bin/autom4te.in, bin/autoreconf.in,
10940 * bin/autoscan.in, bin/autoupdate.in, bin/ifnames.in (BEGIN): Make
10941 them uniform, and more robust to Perl special characters.
10942 Reported by Martin Mokrejs.
10944 2003-05-14 Akim Demaille <akim@epita.fr>
10946 * tests/foreign.at (Libtool): Skip all Libtools pre 1.4.

10961 * lib/Autom4te/XFile.pm (lock, truncate): Do not pass @_ to flock
10962 and truncate.
10964 2003-05-06 Akim Demaille <akim@epita.fr>
10966 Don't try to be smart with aclocal 1.8+ because (i) aclocal no
10967 longer updates aclocal.m4 if useless, (ii) if a file m4_included
10968 by aclocal.m4 is changed it might require the importing of another
10969 m4 extension file, i.e., aclocal must be run.
10971 * bin/autoreconf.in (&run_aclocal, $aclocal_supports_force): New.
10972 (&parse_args): Use --force with aclocal if required and supported.
10973 (&autoreconf_current_directory): Use &run_aclocal.
10975 2003-05-06 Akim Demaille <akim@epita.fr>
10977 Lock autom4te's cache.
10979 * lib/Autom4te/XFile.pm ($me, &name, &lock, &truncate, &seek): New.
10980 * bin/autom4te.in (&Request::save, &Request::load): Use an IO::File
10981 argument instead of a file name, so that the request file remains
10982 open during the whole autom4te run.
10983 ($icache_file): New.
10984 (&freeze): Lock the $icache_file.
10986 2003-04-29 Derek Price <derek@ximbiot.com>
10988 * lib/autotest/general.m4 (AT_KEYWORDS): Don't use a comma as the
10989 seperator with m4_append_uniq(). It doesn't work.
10990 (AT_CLEANUP): Add `;' to end of at_help_all.
10991 (AT_INIT): Allow --keywords to be specified more than once. When
10992 grepping $at_help_all for keywords, use the field and keyword
10993 seperators to ensure a complete keyword match. Alter at_prev handling
10994 to support the new --keywords behavior.
10996 2003-04-27 Karl Berry <karl@freefriends.org>
10998 * doc/autoconf.texi: Make the dir entries in the autoconf manual
10999 align better with others. I also made some of the individual
11000 entries on one line, for brevity and to make it easier for me to
11001 sort my dir-example file in the Texinfo distribution :).
11003 2003-04-12 Jim Meyering <jim@meyering.net>
11005 * NEWS: Mention the new macro.

11042 Use them.
11043 * doc/Makefile.am (CLEANFILES): Adjust.

11060 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): The
11061 documentation to read is Autoconf's.
11062 Suggested by Paul Eggert.
11064 2003-03-28 Akim Demaille <akim@epita.fr>
11066 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): Suggest

11072 * tests/torture.at (Configuring subdirectories): Require aclocal
11073 1.4, otherwise the test fails, as it does support configure.ac.
11074 This fixes the "test 40 failed" bug reports.
11076 2003-03-28 Akim Demaille <akim@epita.fr>
11078 * doc/autoconf.texi (C Compiler): `#line' portability.

11084 layout in order to allow scripting around test groups.
11086 2003-03-27 Derek Price <derek@ximbiot.com>
11088 * lib/autotest/general.m4 (PARSE_ARGS,PARSE_ARGS_END,HELP,HELP_MODES,
11089 HELP_TUNING,HELP_OTHER,HELP_END,PREPARE_TESTS,TESTS_END): Define and
11090 use new diversions in preparation for accepting new arguments and
11091 allowing scripting around tests.

11094 2003-03-26 Derek Price <derek@ximbiot.com>
11096 * lib/autoconf/general.m4 (AC_ARG_VAR): Use AS_HELP_STRING instead of
11097 obsolete AC_HELP_STRING.

11104 2003-03-26 Derek Price <derek@ximbiot.com>
11106 * lib/autotest/general.m4: s/DEFAULT/DEFAULTS/ since it makes more
11107 sense. Verbosify the diversion definitions comment.
11109 2003-03-26 Derek Price <derek@ximbiot.com>
11111 * lib/autotest/general.m4 (AT_INIT): Remove redundant call to
11112 AS_PREPARE.

11124 number overflows.
11125 * lib/autoconf/c.m4 (AC_LANG_SOURCE(C)): Do not generate

11133 file name for the m4 program, when it has an "exe" file extension.
11134 DJGPP's error messages include the error code in brackets -
11135 remove the error code during normalization.

11145 an old Automake change. Discuss NetBSD, FreeBSD, OpenBSD, and
11146 Tru64 make in the "target lookup" section.
11147 (Automake): Automake 1.5+ no longer requires special tools to be
11148 present on the developer's host.
11150 2003-02-26 Richard Dawe <rich@phekda.freeserve.co.uk>
11152 * bin/autoheader.in (BEGIN): For DJGPP SHELL may not be set
11153 to a shell that can handle redirection or quoting correctly.
11154 Override SHELL with the shell detected by configure.
11155 Use of $^O suggested by Tim van Holder.
11156 * bin/autom4te.in (BEGIN): Likewise.

11165 to cope with DOS-style absolute paths, when constructing
11166 ${ac_make}.
11168 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS, _AC_OUTPUT_FILES):
11169 When constructing paths with IFS=:, quote the path. If we're
11170 constructing a DOS-style absolute path, we don't want to split it
11171 on the colon.
11173 * tests/atspecific.m4 (AT_CHECK_CONFIGURE): Fix typo
11174 in description.
11176 2003-02-25 Pavel Roskin <proski@gnu.org>
11178 * bin/autoheader.in: Add missing newline when printing
11179 suggestion how change AC_DEFINE call.
11181 2003-02-24 Paul Eggert <eggert@twinsun.com>
11183 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Fix typo in
11184 2002-09-01 patch by replacing "test -n" with "test -z".
11185 This fixes a bug found by Jeff Painter and reported by Tom Epperly in
11186 <http://mail.gnu.org/archive/html/autoconf/2003-02/msg00139.html>.
11188 * doc/autoconf.texi (Shell Substitutions): test -n -> test -z,
11189 to fix a mismatch between example and discussion.
11191 2003-02-24 Kevin Ryde <user42@zip.com.au>
11193 * doc/autoconf.texi (Limitations of Builtins): Add notes on printf
11194 format starting with "-".
11196 2003-02-20 Alexandre Duret-Lutz <adl@gnu.org>
11198 * doc/autoconf.texi (Limitations of Make): `foo=bar make -e'
11199 is not portable inside Makefile.
11201 2003-02-20 Akim Demaille <akim@epita.fr>
11203 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): When
11204 compiler says yeah, but preproc says nope, compiler is right.
11205 Conversely, prompt the reader to send a bug report to the
11206 maintainers of the package, not of Autoconf.
11208 2003-02-20 Klee Dienes <kdienes@apple.com>
11210 * bin/autoreconf.in (autoreconf_current_directory): Properly
11211 handle an empty aclocal.m4.

11221 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Define $1 to an
11222 innocuous variant befor including <limits.h> or <assert.h>. This
11223 works around a bug reported by Albert Chin: HP-UX 11i
11224 (and earlier versions) have a <limits.h> that declares
11225 gettimeofday and many other functions.
11227 2002-12-03 Paul Eggert <eggert@twinsun.com>
11229 Version 2.57.
11231 * NEWS, configure.ac: Update version.
11233 * doc/fdl.texi: Upgrade to FDL version 1.2.
11235 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Use the function f
11236 nontrivially in main's body, so that f's external declaration is
11237 not optimized away in AIX. This should fix the bug reported by
11238 Martin Frydl in
11239 <http://mail.gnu.org/pipermail/autoconf/2002-November/014508.html>.
11241 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C),
11242 _AC_PROG_PREPROC_WORKS_IFELSE): Use <limits.h> if __STDC__ is
11243 defined, to support freestanding compilers. This should fix the
11244 bug reported by Momchil Velkov in
11245 <http://mail.gnu.org/pipermail/autoconf/2002-November/014490.html>.
11247 * doc/autoconf.texi (Obsolete Macros): Fix typos (insert empty
11248 arg, AC_DEFINE -> AC_DEFINE_UNQUOTED) in documentation for
11249 obsolete AC_CHECK_TYPE. The missing empty arg was reported
11250 by Simon Josefsson in
11251 <http://mail.gnu.org/pipermail/autoconf-patches/2002-December/008830.html>.
11253 * Makefile.maint (www-gnu): New macro.
11254 (standards.texi-url_prefix, make-stds.texi-url_prefix): Use it, as
11255 the location has moved.
11257 2002-12-02 Martin Frydl <martin@systinet.com>
11259 * bin/autom4te.in (at_flatten): rewritten to avoid M4 problem when
11260 \(.*\) match is too long and there is something more to be checked.
11261 <http://mail.gnu.org/pipermail/autoconf/2002-November/014524.html>
11263 2002-11-15 Akim Demaille <akim@epita.fr>
11265 Version 2.56.
11267 * config/install-sh: chmod +x.
11268 From Paul Eggert.
11269 * config/move-if-change: Indenting changes.
11270 * Makefile.am (AUTOMAKE_OPTIONS): Move to...
11271 * configure.ac (AM_INIT_AUTOMAKE): here.
11272 Require 1.7.1.
11274 2002-11-14 Akim Demaille <akim@epita.fr>
11276 Version 2.55.
11278 * config/config.guess, config/config.sub, config/install-sh:
11279 Update from masters.
11281 2002-11-14 Akim Demaille <akim@epita.fr>
11283 * Makefile.maint: Sync with Bison, i.e.:
11284 (po-check): Scan .l and .y files instead of the
11285 .c and the .h files that they generate. This fixes the bug
11286 reported by Tim Van Holder in:
11287 <http://mail.gnu.org/pipermail/bison-patches/2002-November/001352.html>
11288 Look for N_ as well as for _. Try to avoid matching #define for
11289 N_ and _.
11290 From Paul Eggert.
11292 2002-11-14 Akim Demaille <akim@epita.fr>
11294 * doc/autoconf.texi (C Compiler): Compiling several files at once.
11295 From Paul Eggert and Albert Chin-A-Young.
11297 2002-11-14 Akim Demaille <akim@epita.fr>
11299 * doc/autoconf.texi (C Compiler): Solitary backslashes.
11300 From Paul Eggert and Albert Chin-A-Young.
11302 2002-11-14 Kevin Ryde <user42@zip.com.au>
11304 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Initialize f=$1 rather
11305 than assigning in main, to avoid HP cc +O3 optimizing it away.
11307 2002-11-12 Peter Eisentraut <peter_e@gmx.net>
11309 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Add -q
11310 option. Process --recheck after parsing all options. Pass -q
11311 option to configure on --recheck.
11312 (AC_OUTPUT): Pass -q from configure to config.status.
11313 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Strip -q from
11314 arguments to record.
11315 * doc/autoconf.texi (config.status Invocation): Document
11316 config.status -q option.
11318 2002-11-07 Alexandre Duret-Lutz <adl@gnu.org>
11320 * bin/autoscan.in (scan_file): Scan Makefile.am too. Ignore
11321 Makefile.in if Makefile.am exists.
11322 (output): Strip `.am' from Makefiles. Don't
11323 output AC_CONFIG_FILES if no Makefiles were found.
11325 2002-11-07 Akim Demaille <akim@epita.fr>
11327 * Makefile.am (cvs_files): Add elisp-comp, mdate-sh.

11334 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY): Wrap the `f'
11335 declaration in extern "C" too.
11336 Reported by Roberto Bagnara.
11338 2002-11-06 Akim Demaille <akim@epita.fr>
11340 * tests/torture.at (Configuring subdirectories): Don't use grep
11341 -w.
11342 * doc/autoconf.texi (Limitations of Usual Tools): Grep -w.
11343 Reported by Ezra Peisach.
11345 2002-11-05 Akim Demaille <akim@epita.fr>
11347 * lib/autoconf/autoheader.m4 (_AH_TEMPLATE_OLD, _AH_VERBATIM_OLD):
11348 Remove.
11349 We _have_ to stop using the old compatibility scheme that tried to
11350 avoid useless backslashes because Libtool 1.4.3 contains a
11351 AC_DEFINE([error_t], [int],
11352 [Define to a type to use for \`error_t' if it is not
11353 otherwise available.])
11354 We _have_ to quote the single quote and backslashes with \. The
11355 old compatibility scheme saw that ` was backslashed, and therefore
11356 did not quote the single quote. Hence before this patch, Autoconf
11357 was not compatible with Libtool.
11359 2002-11-04 Paul Eggert <eggert@twinsun.com>
11361 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Set the following variables,
11362 too: LC_ADDRESS, LC_IDENTIFICATION, LC_MEASUREMENT, LC_MONETARY,
11363 LC_NAME, LC_PAPER, LC_TELEPHONE.

11366 2002-11-04 Akim Demaille <akim@epita.fr>
11368 Version 2.54c.
11370 * Makefile.maint (update, cvs-update, po-update, do-po-update):
11371 New.
11372 * config/texinfo.tex: Update.
11374 2002-11-03 Akim Demaille <akim@epita.fr>
11376 * bin/autoreconf.in (&autoreconf_current_directory): New, extracted
11377 from...
11378 (&autoreconf): here.
11379 ($help, $make, &parse_args, &autoreconf_current_directory):
11380 Support -m/--make.
11381 * doc/autoconf.texi (autoreconf Invocation): Adjust.
11383 2002-10-31 Bruno Haible <bruno@clisp.org>

11389 to ac_cv_func_realloc_0_nonnull.
11390 (AC_FUNC_REALLOC): Change description of HAVE_REALLOC macro.
11392 2002-10-31 Akim Demaille <akim@epita.fr>
11394 The test suite was no longer checking for trailing envvars and files.
11396 * tests/atspecific.m4 (AC_STATE_SAVE): Don't use quadrigraphs here.
11397 (AT_CHECK_ENV): Make sure the `state-ls.before file exists.
11399 2002-10-31 Akim Demaille <akim@epita.fr>
11401 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Use and display
11402 `$(MAKE)' instead of '${MAKE}' to emphasize that we refer to the
11403 Make variable, not a shell variable.
11404 Suggested by Bruno Haible.
11406 2002-10-31 Akim Demaille <akim@epita.fr>
11408 * bin/autom4te.in (load_configuration): Reject #args out of any
11409 language.
11411 2002-10-31 Akim Demaille <akim@epita.fr>
11413 * lib/autoconf/general.m4 (_AC_MSG_LOG_CONFTEST): New.
11414 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE, _AC_LINK_IFELSE)

11416 * lib/autoconf/lang.m4 (_AC_COMPILER_OBJEXT):
11417 (_AC_COMPILER_EXEEXT_DEFAULT): Likewise.
11418 * lib/autoconf/c.m4 (AC_LANG_SOURCE): Don't include confdefs.h,
11419 inline it.
11421 2002-10-30 Akim Demaille <akim@epita.fr>
11423 * bin/autom4te.in (&parse_args, $help): Support --no-cache.
11424 * doc/autoconf.texi (autom4te Invocation): Adjust.
11425 Suggested by Tim van Holder.
11427 2002-10-29 Paul Eggert <eggert@twinsun.com>
11429 * doc/autoconf.texi (Particular Functions): AC_FUNC_MALLOC and
11430 AC_FUNC_REALLOC check for compatibility with glibc, not POSIX.
11431 Problem reported by Bruno Haible.
11433 2002-10-29 Akim Demaille <akim@epita.fr>
11435 * doc/autoconf.texi (Header Templates): Put also in words what the
11436 pictures says to assist free style readers.
11437 (Customizing autom4te): s/--cache=/--cache /.
11439 2002-10-29 Akim Demaille <akim@epita.fr>
11441 * lib/autoconf/functions.m4 (_AC_FUNC_VFORK): Include stdlib.h and
11442 sys/wait.h.

11455 * tests/torture.at (Deep Package): New test.
11456 (Configuring subdirectories): Don't use a testSubDir as Autotest
11457 now does it itself.
11459 2002-10-29 Akim Demaille <akim@epita.fr>
11461 * bin/autoreconf.in (&parse_args, $help): Support --warnings.
11462 * doc/autoconf.texi (Invoking autom4te): Rename as...
11463 (autom4te Invocation): this, for consistency with the other nodes.
11465 2002-10-29 Akim Demaille <akim@epita.fr>
11467 * lib/autom4te.in (Autoconf): s/automate/autom4te/.
11468 Reported by Ralf Corsepius.
11470 2002-10-29 Akim Demaille <akim@epita.fr>
11472 * lib/m4sugar/m4sh.m4 (_AS_QUOTE): The warning about quoted
11473 characters is a back as an `obsolete' warning now.
11474 Reported by Ralf Corsepius.
11476 2002-10-28 Akim Demaille <akim@epita.fr>
11478 * configure.ac: Bump to 2.54c.

11689 2002-10-22 Akim Demaille <akim@epita.fr>

11703 * lib/autoconf/autoheader.m4 (AH_VERBATIM, _AH_VERBATIM_OLD):
11704 Quote for Perl, not sh.
11705 * bin/autoheader.in: When $debug, report the file which is

11744 2002-10-16 Akim Demaille <akim@epita.fr>
11746 Because of caching, some files that no longer exist and are no
11747 longer required can still cause errors.
11748 Reported by Alexandre Duret-Lutz.
11750 * bin/autom4te.in (&parse_args): Do not prepend `--reload-state'
11751 to frozen files in @ARGV, as @ARGV must remain being a list of

11754 (&freeze): Use &error.
11755 (&up_to_date): If a file that was included according to the cache
11756 is no longer there, then the output is out dated.

11758 --force is given.
11759 * tests/tools.at (autom4te cache): New.
11761 2002-10-16 Akim Demaille <akim@epita.fr>

11764 * bin/autoupdate.in (&parse_args): Kill old options.
11765 * bin/autoreconf.in (&parse_args): Remove dead options.
11766 Factor some code.
11767 (&autoreconf): Report the directories we enter *and leave*, so
11768 that error messages can be easily located, and use GNU Make
11769 format, so that Emacs' compile mode understands us.
11770 * lib/Autom4te/General.pm (&update_file): Use `verbose' to report
11771 if some file was changed instead of `print'.
11772 * bin/autoheader.in: Suggest AC_DEFINE with 3 args when needed.
11773 (&parse_args): Remove the dead options.

11786 (AC_CHECK_HEADER, _AC_CHECK_HEADER_OLD): Remove.

11803 2002-10-11 Akim Demaille <akim@epita.fr>
11805 * lib/m4sugar/m4sh.m4 (_AS_PATH_SEPARATOR_PREPARE): Use $$ in the
11806 file name to enable parallel executions.
11807 From Sam Varshavchik.
11809 2002-10-08 Akim Demaille <akim@epita.fr>
11811 * bin/autoreconf.in (&autoreconf): Run autopoint before the first
11812 aclocal invocation, as Gettext macros might not be visible to
11813 aclocal.
11814 Instead of blindly running autopoint, scan configure.ac (not the
11815 traces) for AM_GNU_GETTEXT_VERSION uses, as autopoint does.
11816 Reported by Paul D. Smith.
11818 2002-10-08 Paul Eggert <eggert@twinsun.com>
11820 Work around problems found when POSIXLY_CORRECT=1 is set.
11821 None of this seems to have anything to do with POSIX, really,
11822 but it's how Perl getopt works.
11823 * bin/autom4te.in (parse_args): Configure GetOpt with
11824 "permute", too.
11825 * doc/autoconf.texi (Invoking autom4te):

11848 * tests/torture.at (Configuring subdirectories): Be robust to
11849 users who use config.site to require for a cache: in this case,
11850 the two last configure runs, using two different sets of
11851 arguments, trigger a legitimate error.
11853 2002-09-28 Akim Demaille <akim@epita.fr>
11855 * tests/m4sh.at (Functions Support, Functions and return Support):
11856 New.

11863 (autom4te): Specify that the sources are in the $srcdir.
11864 * doc/autoconf.texi (Installation Directory Variables): Adjust.
11866 2002-09-28 Akim Demaille <akim@epita.fr>
11868 * lib/autoscan/autoscan.pre (st_blksize, st_blocks, st_rdev)
11869 (tm_zone): Move their rules to...
11870 * lib/autoconf/types.m4: here, using AN_ macros.
11871 * lib/autoscan/autoscan.pre (AWK, BISON, INSTALL, LEX, LN, MAKE)
11872 (RANLIB, YACC, awk, bison, byacc, flex, gawk, install, lex, ln)

11886 * lib/freeze.mk (autoconf_m4f_dependencies): Add autoscan.m4.
11887 (.m4.m4f): Don't pass --prepend-include, since that's done by
11888 tests/autom4te itself.
11889 * lib/autoscan/Makefile.am: Include freeze.mk.
11890 (autoscan.list): New target --this file is no longer a source.
11891 (autoscan.pre): New file.
11893 2002-09-28 Akim Demaille <akim@epita.fr>
11895 * bin/autoscan.in (@kinds): Make them singular.
11896 Adjust all uses.

11898 tracking changes in autoscan.list.

11915 * bin/autoscan.in (&init_tables): Adjust.
11917 2002-09-28 Akim Demaille <akim@epita.fr>
11919 From now on, autoscan files must always map a macro name to a
11920 word: there is no `default' macro for autoscan.
11922 * bin/autoscan.in (&init_tables): Reject entries with no macro at
11923 all.
11924 * lib/autoscan/functions, lib/autoscan/headers: Make the macro
11925 explicit.
11927 2002-09-28 Akim Demaille <akim@epita.fr>

11963 * doc/autoconf.texi (autoreconf Invocation): Likewise.
11965 2002-09-26 Akim Demaille <akim@epita.fr>

11971 Separated Dependencies'.
11972 * bin/Makefile.am (autoconf, autoheader, autoreconf, autoupdate)
11973 (ifnames, autoscan, autom4te): Un-factor into several rules.
11975 2002-09-25 Paul Eggert <eggert@twinsun.com>
11977 * BUGS (Interoperability bugs): New section. Mention libtool
11978 1.4.2, configure.ac, and AC_CONFIG_AUX_DIR interoperability bug.
11980 2002-09-24 Paul Eggert <eggert@twinsun.com>
11982 Fix a portability bug reported by Alexandre Duret-Lutz: Solaris 8
11983 make handles suffix-rules differently from GNU make.

11986 (autoconf autoheader autoreconf autoupdate ifnames autoscan autom4te):
11987 Move the body of the old .in rule here.
11989 2002-09-16 Akim Demaille <akim@epita.fr>
11991 i960 compilers create `b.out' files by default.
11992 Reported by Ralf Corsepius.
11994 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT): Remove b.out files.
11995 (_AC_COMPILER_EXEEXT_DEFAULT): Adjust to b.out.
11997 2002-09-13 Paul Eggert <eggert@twinsun.com>
11999 * doc/autoconf.texi (Particular Headers): Remove obsolete
12000 reference to `struct timezone' in the description of
12001 AC_HEADER_TIME.
12003 2002-09-13 Akim Demaille <akim@epita.fr>
12005 Version 2.54.
12007 * config/config.sub, config/config.guess: Update.
12008 * Makefile.maint: Update from bits of the Coreutils 4.5.1.
12009 * Makefile.am: Adjust.
12011 2002-09-13 Akim Demaille <akim@epita.fr>
12013 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Suggest
12014 reading config.log when the compiler is rejected.
12015 Suggested by Guido Draheim.
12017 2002-09-13 Akim Demaille <akim@epita.fr>
12019 * bin/autoreconf.in: Don't use Cwd::chdir, since in its internals
12020 (chdir_init) might hang when stat'ing mounted directories.
12021 Reported by Vance Shipley.
12023 2002-09-12 Akim Demaille <akim@epita.fr>
12025 * bin/autoscan.in (&parse_args): Pass a reference to the lists, not
12026 the lists.
12028 2002-09-12 Akim Demaille <akim@epita.fr>
12030 * doc/autoconf.texi (Defining Symbols): Present two different
12031 prototypes for AC_DEFINE and AC_DEFINE_UNQUOTED to emphasize the
12032 difference between 1 argument calls, and 2-3 argument calls.
12034 2002-09-12 Peter Eisentraut <peter_e@gmx.net>
12036 * doc/autoconf.texi: Review grammar and punctuation.
12038 2002-09-11 Paul Eggert <eggert@twinsun.com>
12040 * doc/autoconf.texi: Fix minor formatting, spelling, and
12041 grammatical typos.
12042 (Defining Symbols): Explain that AC_DEFINE(var) defaults to 1, but
12043 AC_DEFINE(var,,description) does not; and the AC_DEFINE(var) case
12044 is obsolescent.
12046 2002-09-11 Akim Demaille <akim@epita.fr>
12048 * doc/autoconf.texi (Questions): Rename as...
12049 (FAQ): this.
12050 (Defining Directories): New.
12052 2002-09-09 Akim Demaille <akim@epita.fr>
12054 * doc/autoconf.texi (Making testsuite Scripts): Update.
12055 Suggested by Nishio Futoshi.
12057 2002-09-09 Koji Arai <JCA02266@nifty.ne.jp>
12059 * doc/autoconf.texi (Making testsuite Scripts): Use `@@' where a
12060 plain `@' is wanted.
12062 2002-09-09 Akim Demaille <akim@epita.fr>
12064 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Keep the
12065 `duplicates', since the algorithm was too naive and could keep
12066 `--prefix=1 --prefix=2 --prefix=1' as `--prefix=1 --prefix=2', and
12067 keep `--prefix foo --prefix bar' as `--prefix foo bar'.
12068 Reported by Ralf Corsepius.
12069 * tests/torture.at (Configuring subdirectories): Exercise these
12070 cases.
12072 2002-09-09 Akim Demaille <akim@epita.fr>
12074 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Use $srcdir when
12075 looking for a replacement file.
12076 * lib/autoconf/general.m4 (AC_CHECK_DECLS): Check that the
12077 directory is relative.
12078 * doc/autoconf.texi (Generic Functions): Clarify the replacement
12079 directory definition.
12080 Reported by Andreas Schwab and Jim Meyering.
12082 2002-09-06 Akim Demaille <akim@epita.fr>
12084 * doc/autoconf.texi (Setting Output Variables): Clarify what
12085 precious variables are.
12086 Suggested by Pontus Skoeld.
12088 2002-09-05 Akim Demaille <akim@epita.fr>
12090 * bin/Makefile.am (autoconf, autoheader, autoreconf, autoupdate)
12091 (ifnames, autoscan, autom4te): Since we don't only depend on
12092 configure.ac variables (such as VERSION etc.), but also on prefix
12093 and so forth, depend on Makefile, not configure.ac.
12094 Reported by Alexandre Duret-Lutz.
12095 * doc/autoconf.texi (Installation Directory Variables): Adjust.
12097 2002-09-05 Kevin Ryde <user42@zip.com.au>
12099 * doc/autoconf.texi (Limitations of Make): HP-UX trailing backslashes
12100 doesn't seem to be confined to ia64, just say "some versions".
12102 2002-09-04 Akim Demaille <akim@epita.fr>
12104 * Makefile.am, doc/Makefile.am: Remove pdf targets, handled by
12105 Automake 1.6c.
12106 * Makefile.am (maintainer-clean-local): Remove.
12107 (MAINTAINERCLEANFILES): Remove COPYING.
12109 2002-09-03 Paul Eggert <eggert@twinsun.com>
12111 * doc/autoconf.texi (Configuration Commands): Remove obsolete
12112 example for AC_CONFIG_COMMANDS_PRE. Problem reported by Marcus
12113 Brinkmann.
12115 2002-09-03 Akim Demaille <akim@epita.fr>
12117 * configure.ac: Bump to 2.53d.
12118 * Makefile.am (AUTOMAKE_OPTIONS): Require 1.6c, i.e., CVS Automake
12119 as of today, on Automake's team suggestion.
12121 2002-09-03 Akim Demaille <akim@epita.fr>
12123 Version 2.53c.
12125 2002-09-02 Akim Demaille <akim@epita.fr>
12127 * bin/autom4te.in (parse_args): Don't honor AUTOM4TE_PATH and
12128 SITE_MACRO_DIR.
12129 * configure.ac: Disable SITE_MACRO_DIR.
12131 2002-09-02 Jim Meyering <meyering@lucent.com>
12133 * doc/autoconf.texi (AC_SYS_POSIX_TERMIOS): Reflect renaming: s/am/ac/,
12134 i.e., change am_cv_sys_posix_termios to ac_cv_sys_posix_termios.
12135 Also, tweak grammar: s/make sure to/be sure to/.
12137 2002-09-02 Paul Eggert <eggert@twinsun.com>
12139 * doc/autoconf.texi (Limitations of Builtins): Explain why logical
12140 directory names are generally preferable to physical names.
12142 2002-09-02 Akim Demaille <akim@epita.fr>
12144 * lib/Autom4te/General.pm (&update_file): s/die/error/.
12145 Reported by Raja R. Harinath.
12146 * bin/autoheader.in, bin/autoreconf.in, bin/autoscan.in,
12147 * bin/autoupdate.in: Use error instead of die.
12149 2002-09-01 Paul Eggert <eggert@twinsun.com>
12151 * tests/mktests.sh (ac_exclude_egrep, au_exclude_egrep): Use
12152 ordinary shell concatenation rather than echo+tr+sed command that
12153 runs afoul of a long-line-related sed bug in Solaris 8.
12155 * bin/autoheader.in (parse_args): --warning -> --warnings.
12157 * bin/autoconf.as: Work even if "ls" outputs "FOO not found" to
12158 stdout, as traditional "ls" does.
12159 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT,
12160 _AC_COMPILER_EXEEXT_O): Likewise.
12161 * doc/autoconf.texi (Limitations of Usual Tools): Add "ls".
12163 * bin/autoconf.as: Add --prepend-include option. This patch was
12164 applied to bin/autoconf.in in the 2002-07-17 patch by Mark D. Roth,
12165 but bin/autoconf.in is generated automatically from bin/autoconf.as.
12167 * bin/autoconf.in, configure: Regenerate.
12169 * doc/autoconf.texi (Special Shell Variables): Mention
12170 ENV, MAIL, MAILPATH, PS1, PS2, PS4. Index PWD.
12172 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Unset ENV, MAIL,
12173 MAILPATH and set PS1, PS2, PS4 to default values, to work
12174 around bug in pre-3.0 UWIN ksh reported by Bruce Lilly.
12175 For LC_ALL etc, first try to set to "C" as POSIX requires and as
12176 the Autoconf documentation specifies; fall back to "unset" only if
12177 this fails. Use a shell for-loop for this rather than an m4 loop,
12178 to shorten the output script.
12180 2002-08-30 Paul Eggert <eggert@twinsun.com>
12182 * doc/autoconf.texi (Special Shell Variables): Mention POSIX
12183 1003.1-2001's requirements for CDPATH. Give a simpler workaround
12184 for the CDPATH problem. Document PWD.
12185 (Limitations of Builtins): Document the problem that "cd $foo" and
12186 "ls $foo" may refer to different directories in shells conforming
12187 to POSIX 1003.1-2001. Use PS1 rather than CDPATH for "unset"
12188 example, since the old example is now out of date.
12190 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Reject FOO if "cd
12191 FOO" and "ls FOO" talk about different directories; this catches
12192 problems when POSIX 1003.1-2001 "cd" fails due to symlink
12193 spaghetti.
12195 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Use AS_UNSET instead
12196 of rolling our own unset.
12197 (_AS_PREPARE): $as_unset CDPATH instead of AS_UNSETting it, since
12198 in practice we needn't worry about CDPATH if unset doesn't work.
12200 * Makefile.in, aclocal.m4, bin/Makefile.in,
12201 config/Makefile.in, doc/Makefile.in, lib/Makefile.in,
12202 lib/Autom4te/Makefile.in, lib/autoconf/Makefile.in,
12203 lib/autoscan/Makefile.in, lib/autotest/Makefile.in,
12204 lib/emacs/Makefile.in, lib/m4sugar/Makefile.in, man/Makefile.in,
12205 tests/Makefile.in: Regenerate with Automake 1.6.3.
12207 * config/config.guess, config/config.sub, config/mkinstalldirs:
12208 Update.
12210 * configure: Regenerate with self.
12212 2002-08-30 Kevin Ryde <user42@zip.com.au>
12214 * doc/autoconf.texi (Limitations of Usual Tools): Notes on "cc"
12215 default output.
12217 2002-08-29 Rainer Orth <ro@TechFak.Uni-Bielefeld.DE>
12219 * bin/autom4te.in (Request::load): Correctly test for "do" read
12220 failure.
12222 2002-08-29 Akim Demaille <akim@epita.fr>
12224 * lib/Autom4te/General.pm (&xqx): New.
12225 (&xsystem): Use WIFEXITED and WEXITSTATUS instead of decoding $? by
12226 hand, which is not portable.
12227 (&error): New.
12228 * bin/autom4te.in: Use them.
12229 Use &error instead of die.
12230 * tests/m4sugar.at (m4_warn, m4_require: circular dependencies):
12231 Adjust.
12233 2002-08-17 Paul Eggert <eggert@twinsun.com>
12235 * lib/autoconf/fortran.m4 (AC_PROG_F77): Remove fc from the
12236 default list of compilers to try, since it was long ago superseded
12237 by the ksh fc builtin. Suggested by Steven G. Johnson.
12239 2002-07-31 Alexandre Duret-Lutz <duret_g@epita.fr>
12241 * doc/autoconf.texi (Invoking autom4te): End the option table,
12242 fixing a bug introduced by the previous patch.
12243 (Limitations of Make): Add a 'target lookup' subentry in the
12244 'VPATH' entry. Rewrite all `make' occurences as `@command{make}'.
12246 2002-07-29 Mark D. Roth <roth@feep.net>
12248 * bin/autom4te.in: Remove --include-envvar and --site-macro-subdir
12249 options and use $AUTOM4TE_PATH.
12250 * doc/autoconf.texi: Remove documentation of autom4te
12251 --include-envvar and --site-macro-subdir options and document
12252 use of $AUTOM4TE_PATH.
12253 * lib/autom4te.in: Remove --include-envvar and --site-macro-subdir
12254 arguments from each language section.
12256 2002-07-29 Paul Eggert <eggert@twinsun.com>
12258 * doc/install.texi: Include copyright symbol in copyright notice.
12260 * Makefile.am (MAKEINFO): Remove; it's a user-specified macro.
12261 Replace with:
12262 (AM_MAKEINFOFLAGS): New macro.
12263 * doc/Makefile.am (MAKEINFO, AM_MAKEINFOFLAGS): Likewise.
12264 * Makefile.am (INSTALL): Use the new macros.
12265 Use -o rather than --output, since "missing" does not grok --output.
12267 2002-07-25 Alexandre Duret-Lutz <duret_g@epita.fr>
12269 * doc/autoconf.texi (Limitations of Make): Escaped newlines in
12270 comments do not always work. Never trust the exit status of
12271 `make -k'.
12273 2002-07-24 Kevin Ryde <user42@zip.com.au>
12275 * doc/autoconf.texi (Limitations of Make, Making testsuite Scripts):
12276 Untabify, since tabs are not enjoyed by texi2dvi and makeinfo.
12278 2002-07-23 Paul Eggert <eggert@twinsun.com>
12280 * lib/m4sugar/m4sh.m4 (_AS_PATH_SEPARATOR_PREPARE):
12281 Use PATH="/nonexistent;.", not PATH=".;.", as FreeBSD ksh2002
12282 apparently treats PATH="nonexistent" as if it contained ".".
12283 Bug reported by Stefan `Sec' Zehl.
12285 2002-07-22 Alexandre Duret-Lutz <duret_g@epita.fr>
12287 * doc/autoconf.texi (Limitations of Make): Mention the special
12288 handling of the obj/ directory by BSD make.
12290 2002-07-20 Kevin Ryde <user42@zip.com.au>

12298 (Programming in M4sh): Ethymology of M4sh.
12300 2002-07-19 Akim Demaille <akim@epita.fr>
12302 * doc/autoconf.texi (AC_LIBOBJ vs LIBOBJS): More about $U.
12304 2002-07-18 Akim Demaille <akim@epita.fr>
12306 Version 2.53b.
12308 2002-07-18 Akim Demaille <akim@epita.fr>
12310 * config/config.guess, config/config.sub: Update.
12312 2002-07-18 Akim Demaille <akim@epita.fr>
12314 Handle LIBOBJS and LTLIBOBJS once for all, including Libtool's and
12315 Automake's parts.
12317 * lib/autoconf/general.m4 (_AC_LIBOBJS_NORMALIZE): New.
12318 * lib/autoconf/status.m4 (AC_OUTPUT_COMMANDS_PRE): Call it.
12319 * tests/semantics.at (AC_REPLACE_FUNCS): Adjust.

12325 _AC_AM_CONFIG_HEADER_HOOK for Automake 1.7.
12327 2002-07-17 Russ Allbery <rra@stanford.edu>

12334 * lib/autoconf/functions.m4 (AC_FUNC_FORK): Don't set
12335 ac_cv_func_fork_works before running _AC_FUNC_FORK, do it if the
12336 latter was not run.
12338 2002-07-17 Akim Demaille <akim@epita.fr>
12340 * lib/Autom4te/General.pm (find_file): Browse the directories in
12341 the order they are given.

12361 macro directory, remove note that include path directories are

12363 * lib/autom4te.in: Use --prepend-include instead of --include.
12364 * tests/wrapsh.in: Use --prepend-include instead of --include.
12366 2002-07-17 Akim Demaille <akim@epita.fr>

12407 so that Emacs setups GNU style for perl-mode and cperl-mode.
12409 2002-06-27 Paul Eggert <eggert@twinsun.com>
12411 * config/install-sh: Quote $src. Prefer || to test's -o option,
12412 as per "Limitations of Builtins".
12413 * tests/atspecific.m4 (AT_CHECK_ENV): Likewise, for && vs test -a.
12414 * tests/semantics.at (AC_C_BIGENDIAN): Likewise.
12416 * tests/mktests.sh: Use grep instead of fgrep, as per
12417 "Limitations of Builtins".

12421 * tests/wrapsh.as (AUTOCONF, AUTOHEADER, AUTOM4TE, AUTOM4TE_CFG,
12422 autom4te_perllibdir): Set to top build dir or src dir as appropriate,
12423 so that we consistently test the just-built programs.
12424 * tests/wrappl.as: Likewise.
12426 2002-06-12 Paul Eggert <eggert@twinsun.com>
12428 * bin/autoconf.as (AUTOM4TE): Default to a fully qualified path
12429 name, so that symlinks to 'autoconf' work properly. Bug reported
12430 by Bruno Haible.
12431 * bin/autoheader.in (AUTOM4TE): Likewise.
12432 * bin/autoreconf.in (autoconf, autoheader): Likewise.

12444 2002-06-10 Alexandre Duret-Lutz <duret_g@epita.fr>

12447 of the cache should not depend on the name under which autom4te
12448 was installed.

12474 2002-06-07 Akim Demaille <akim@epita.fr>
12476 * bin/autom4te.in (warn_forbidden): When rejecting a token,
12477 suggest m4_pattern_allow.
12478 Suggested by Adam J. Richter.
12480 2002-06-07 Akim Demaille <akim@epita.fr>
12482 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Initialize
12483 ac_config_libobj_dir.
12484 (AC_CONFIG_LIBOBJ_DIR): New.
12485 * lib/autoconf/functions.m4 (_AC_FUNC_FNMATCH): Split into...

12544 from the default list of compilers to try. Suggested by
12545 Kate Hedstrom.
12546 * NEWS: Document the above.

12549 2002-05-17 Paul Eggert <eggert@twinsun.com>
12551 * lib/autoconf/types.m4 (AC_CHECK_MEMBER): Work correctly even if
12552 the member is itself an aggregate. Bug reported by Sergey Poznyakoff.
12553 This improves on an earlier suggestion by H. Peter Anvin.
12555 2002-05-16 Paul Eggert <eggert@twinsun.com>
12557 AC_FUNC_FNMATCH now tests only for POSIX compatibility.
12558 AC_FUNC_FNMATCH_GNU also tests for GNU extensions.
12559 Both macros now accept an optional source-dir arg.
12560 New macro AC_GNU_SOURCE to define _GNU_SOURCE.
12562 * NEWS: Document this.
12563 * doc/autoconf.texi (Particular Functions, UNIX Variants): Likewise.
12565 * lib/autoconf/functions.m4 (_AC_FUNC_FNMATCH): New macro.
12566 (AC_FUNC_FNMATCH): Use it. Test only for POSIX conformance,
12567 not for GNU extensions; this undoes part of the 2000-11-03 change,
12568 reverting to 2.13-compatible behavior.
12569 Add new optional argument DIR.
12570 (AC_FUNC_FNMATCH_GNU): New macro.
12572 * lib/autoconf/specific.m4 (AC_GNU_SOURCE): New macro.
12574 2002-05-08 Paul Eggert <eggert@twinsun.com>
12576 * lib/autoconf/headers.m4 (AC_HEADER_TIOCGWINSZ):
12577 Don't require AC_SYS_POSIX_TERMIOS. The test is unnecessary,
12578 and it causes a 'test' syntax error if it fails.
12579 Bug reported by Stephen Gildea.
12581 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
12582 If prototypes are supported, use them to check this at compile-time,
12583 instead of trying to check it at run-time. If we must do a run-time
12584 check, assume that setvbuf is standard when cross-compiling, as
12585 nonstandard setvbuf occurs only on ancient and unlikely hosts.
12586 Bug reported by Paul D. Smith.
12588 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Add optional
12589 argument specifying location of getloadavg.c. This removes a
12590 FIXME. This idea was taken from Jim Meyering's implementation in
12591 textutils.
12592 * doc/autoconf.texi (Particular Functions): Document this.
12593 Also, mention HAVE_NLIST_H rather than NLIST_STRUCT, since
12594 that's what the code does; this fixes a bug reported by
12595 Paul D. Smith.
12597 2002-05-03 Akim Demaille <akim@epita.fr>
12599 * bin/autoreconf.in (autoreconf): Rewrite to use Gettext's
12600 autopoint instead of gettextize.
12601 ($uses_alocal): Rename as...
12602 ($uses_aclocal): this.
12603 * doc/autoconf.texi (autoreconf Invocation): Adjust.
12604 Suggested by Bruno Haible.
12606 2002-05-03 Akim Demaille <akim@epita.fr>
12608 * lib/m4sugar/m4sugar.m4 (m4_map_sep): New.
12610 2002-04-29 Paul Eggert <eggert@twinsun.com>
12612 * bin/autoreconf.in (autoreconf): Don't age aclocal.m4's input
12613 files to be 1 second older; just set them to be the same time.
12614 Also, sleep 1 second after the first aclocal, to work around
12615 problems with sub-second time stamps on the input files.
12617 2002-04-29 Thien-Thi Nguyen <ttn@gnu.org>
12619 * doc/autoconf.texi: Mention "set -e -x" lossage
12620 under node "Limitations of Builtins".
12622 2002-04-29 Akim Demaille <akim@epita.fr>
12624 * doc/install.texi: Better wording for setting variables when
12625 running configure.
12626 From Christian Cornelssen.
12628 2002-04-29 Akim Demaille <akim@epita.fr>
12630 * tests/m4sh.at (LINENO): If testsuite itself is rewritten because
12631 of lack of $LINENO support, then the test will compare the $LINENO
12632 in testsuite vs. the lineno in the test file. This is wrong, of
12633 course.
12634 Be sure to protect it.
12635 Reported by Patrick Welche.
12637 2002-04-25 Akim Demaille <akim@epita.fr>
12639 * doc/autoconf.texi (Obsolete Macros): Typo.
12640 Reported by Vladimir Volovich.
12642 2002-04-25 Akim Demaille <akim@epita.fr>
12644 * bin/autoreconf.in (autoreconf): Don't let aclocal.m4 be older
12645 than some of the input files, hence, on the second run of aclocal,
12646 if some of its input are younger, make them older.
12647 Suggested by Paul Eggert.
12649 2002-04-25 Akim Demaille <akim@epita.fr>
12651 * doc/autoconf.texi (Limitations of Usual Tools): sed and `!'.
12652 Thanks to Paul Eggert.
12654 2002-04-25 Akim Demaille <akim@epita.fr>
12656 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Let ac_subst_files
12657 and ac_subst_vars be sh variables containing the list of
12658 AC_SUBST_FILES'ed and AC_SUBST'ed identifiers. Output them in the
12659 DEFAULT diversion.
12660 (_AC_INIT_PREPARE): Use them to log them.
12661 (_AC_SUBST, _AC_SUBST_SED_PROGRAM): Remove.
12662 (AC_SUBST, AC_SUBST_FILE): Instead of buliding the
12663 _AC_SUBST_SED_PROGRAM, store the list of output files/variables in
12664 _AC_SUBST_FILES and _AC_SUBST_VARS.
12665 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Adjust.
12667 2002-04-24 Akim Demaille <akim@epita.fr>
12669 * bin/autoreconf.in (autoreconf): Run automake after autoconf and
12670 autoheader, so that automake does not complain about a missing
12671 config.h.in that was to be created.
12673 2002-04-23 Akim Demaille <akim@epita.fr>
12675 * bin/autoheader.in (parse_args): --warning takes an argument.
12676 Fixes PR/220.

12725 Minor spelling and grammar fixes.
12727 * doc/autoconf.texi: Follow the outline suggested in the GNU
12728 Sample Texts sections of the Texinfo 4.2 manual. Most
12729 importantly, this makes sure that the copyright notices appear in
12730 all output formats. You probably need Texinfo 4.2 to generate
12731 the manual now.
12733 Fix some bugs when using "$@" when there might be zero positional

12782 Adjust Autoconf and Autotest.
12784 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Don't invoke
12785 AS_SHELL_SANITIZE, AS_INIT did it, but invoke AS_PREPARE.
12786 * lib/autotest/general.m4 (AT_INIT): Likewise.
12787 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):

12834 (AC_CONFIG_LINKS): here.
12835 Adjust.
12836 Don't use the KILL diversion, as it kills spurious output, which
12837 results in failures being hidden.
12838 Use m4_defn where appropriate.

12840 after the second argument.
12841 Use m4_defn.

12898 2002-03-26 Akim Demaille <akim@epita.fr>
12900 * doc/autoconf.texi (Introduction): The GNATS base moved.
12902 2002-03-25 Paul Eggert <eggert@twinsun.com>
12904 * tests/m4sh.at: Don't rely on "PATH=test:$PATH test-1" working
12905 as POSIX requires, as it doesn't work with Zsh.
12906 * doc/autoconf.texi (Assignments): Document the problem.
12908 2002-03-25 Alexandre Duret-Lutz <duret_g@epita.fr>
12910 * doc/autoconf.texi (Limitations of Make): Mention more issue
12911 about VPATH, overriding of macros in sub-makes, and handling of
12912 SHELL.
12914 2002-03-21 Paul Eggert <eggert@twinsun.com>
12916 * doc/autoconf.texi (Here-Documents): Mention Solaris 8 dtksh
12917 problem with here-document buffer boundaries.
12919 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Unset ENV and BASH_ENV
12920 when reinvoking the shell, to work around problems with installers
12921 who put strange things like "cd" commands in their environments.
12923 2002-03-19 Akim Demaille <akim@epita.fr>
12925 * tests/semantics.at (AC_C_BIGENDIAN): s/unknow/unknown/.
12926 From Aaron Ucko.
12928 2002-03-19 Akim Demaille <akim@epita.fr>
12930 * bin/autoscan.in (scan_file): Specify the location in `&used'
12931 invocations.
12932 From Nicolas Joly.
12934 2002-03-19 Akim Demaille <akim@epita.fr>
12936 * doc/autoconf.texi: Adjust @code/@command, @xref/@ref usage.
12937 From Nishio Futoshi.
12939 2002-03-19 Akim Demaille <akim@epita.fr>
12941 * lib/m4sugar/m4sugar.m4 (m4_define_default, m4_fst, m4_map): New.
12943 2002-03-18 Paul Eggert <eggert@twinsun.com>
12945 * doc/autoconf.texi (Programming in M4sh): Add AS_MKDIR_P.
12946 (Limitations of Usual Tools): Add mkdir section.
12948 * lib/m4sugar/m4sh.m4 (_AS_MKDIR_P_PREPARE): New macro.
12949 (AS_MKDIR_P): Require it. Use mkdir -p if available, falling
12950 back on AS_DIRNAME to compute prefixes otherwise; this is
12951 roughly what mkinstalldirs does. That way, we need not have
12952 our own filename disassembler. The old disassembler did not
12953 work with Solaris 8 dtksh, which is ksh Version M-12/28/93d.
12955 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP):
12956 Create at_test_all by a series of assignments,
12957 not by a single assignment of a long string. The latter causes ksh
12958 version 11/16/88g to silently misbehave on OpenServer 5.0.6a,
12959 presumably because of a buffer overrun.
12961 2002-03-14 Paul Eggert <eggert@twinsun.com>
12963 * lib/autotest/general.m4 (at_times_skip):
12964 Renamed from at_times. Now a boolean.
12965 ksh93 Version M-12/28/93d doesn't like 'x=times; $x'; it
12966 says 'times: not found'.
12968 2002-03-14 Akim Demaille <akim@epita.fr>
12970 * bin/autoreconf.in (&study_gettextize): New.
12971 (&autoreconf): Handle newest gettextize.
12972 Rerun aclocal if needed.
12973 Suggested by Andreas Schwab.
12975 2002-03-13 Akim Demaille <akim@epita.fr>
12977 * doc/autoconf.texi (Special Shell Variables): More about IFS.
12979 2002-03-13 Akim Demaille <akim@epita.fr>
12981 * doc/autoconf.texi (Header Portability): New.
12982 Add information about stdint.h and inttypes.h from Paul Eggert.
12984 2002-03-13 Akim Demaille <akim@epita.fr>
12986 * doc/autoconf.texi (Limitations of Usual Tools): Some about `cp
12987 -p'.
12988 From Bob Proulx.
12990 2002-03-12 Akim Demaille <akim@epita.fr>
12992 * lib/m4sugar/m4sh.m4 (AS_BASENAME_EXPR): AS_REQUIRE, not
12993 m4_require.
12995 2002-03-11 Andreas Schwab <schwab@suse.de>
12997 * configure.ac: Explicitly check for EMACS since AM_PATH_LISPDIR
12998 does not do it if --with-lispdir is given.
13000 2002-03-08 Akim Demaille <akim@epita.fr>
13002 Version 2.53.
13004 2002-03-08 Akim Demaille <akim@epita.fr>
13006 * doc/autoconf.texi (Subdirectories): Clarify that the
13007 subdirectory should exist.
13009 2002-03-08 Akim Demaille <akim@epita.fr>
13011 * Makefile.am (AUTOMAKE_OPTIONS): 1.6.
13013 2002-03-08 Akim Demaille <akim@epita.fr>
13015 * bin/autom4te.in (&handle_m4): Do not foreach with `$_' as it
13016 aliases the actual variables, and modifications of the former
13017 affect the latter.
13019 2002-03-08 Akim Demaille <akim@epita.fr>
13021 * bin/autom4te.in (&handle_m4): Protect us from corrupted file
13022 because of C-c: have m4 output in tmp files, then mv them.
13024 2002-03-08 Akim Demaille <akim@epita.fr>
13026 * bin/autoconf.in, bin/autoheader.in, bin/autom4te.in,
13027 * bin/autoreconf.in, bin/autoscan.in, bin/autoupdate.in,
13028 * bin/ifnames.in: Copyright update.
13030 2002-03-08 Akim Demaille <akim@epita.fr>
13032 * doc/autoconf.texi (Invoking autom4te): New.
13034 2002-03-05 Akim Demaille <akim@epita.fr>
13036 * doc/autoconf.texi (Specifying Names): Clarification suggested by
13037 Kevin Ryde.
13039 2002-03-05 Akim Demaille <akim@epita.fr>
13041 Version 2.52i.
13043 2002-03-04 Akim Demaille <akim@epita.fr>
13045 * doc/autoconf.texi (AC_LIBOBJ vs. LIBOBJS): New.
13046 * lib/autoconf/general.m4 (AC_INIT): More informative error
13047 message for LIBOBJ.
13049 2002-03-04 Akim Demaille <akim@epita.fr>
13051 * lib/freeze.mk ($(build_libdir)/m4sugar/version.m4): New, for
13052 parallel builds.
13054 2002-03-04 Akim Demaille <akim@epita.fr>
13056 * doc/autoconf.texi (Transforming Names): Equality between target
13057 and host is irrelevant.
13058 (Specifying Names, Canonicalizing): Remove all references to the
13059 backward compatibility hooks. Rather, collect them all into...
13060 (Hosts and Cross-Compilation): this new section.
13061 * doc/install.texi (System Type): Ditto.
13062 * lib/autoconf/general.m4 (AC_CANONICAL_HOST): Explicitly state
13063 that `--host' implies cross-compilation.
13065 2002-03-04 Akim Demaille <akim@epita.fr>
13067 * doc/autoconf.texi (Evaluation Macros): New.
13068 * lib/m4sugar/m4sugar.m4 (m4_lquote): Remove, it is totally
13069 useless.
13070 (_m4_foreach): Define the variant with immediate evaluation so
13071 that it contains exactly the items, not an expression which
13072 evaluation is the current item.
13073 (m4_re_string, m4_re_word): Don't over quote them.
13075 2002-03-04 Akim Demaille <akim@epita.fr>
13077 Instead of having stacking `shift's evaluated at the end, let
13078 `foreach' loops immediately evaluate them.
13080 * lib/m4sugar/m4sugar.m4 (m4_quote, m4_dquote): Use $@ rather than
13081 $*. This is the n-th time I change my mind, but hopefully this is
13082 the last...
13083 (m4_lquote): New.
13084 (m4_text_wrap): Use m4_foreach, which is finally correct _and_
13085 efficient.
13086 (m4_foreach_quoted, m4_car_quoted, _m4_foreach_quoted): Remove, as
13087 it was only a hack for m4_text_wrap.
13088 (m4_car2): Remove, replaced by...
13089 (m4_cdr): New.
13090 (_m4_foreach): Adjust.
13091 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Adjust, and use
13092 m4_bpatsubst for clarification.
13094 2002-03-04 Akim Demaille <akim@epita.fr>
13096 * doc/autoconf.texi (Changequote is Evil): New.
13098 2002-03-03 Kevin Ryde <user42@zip.com.au>
13100 * doc/autoconf.texi (Portable Shell): Mention 32-byte #! length limit
13101 on old systems like SunOS.
13103 2002-03-01 Peter Eisentraut <peter_e@gmx.net>

13123 From Akinori Musha.
13125 2002-02-13 Alexandre Duret-Lutz <duret_g@epita.fr>
13127 * lib/Autom4te/XFile.pm (getline, getlines): New functions,
13128 translate \r\n to \n.
13130 2002-02-07 Akim Demaille <akim@epita.fr>
13132 Version 2.52h.
13134 2002-02-07 Akim Demaille <akim@epita.fr>
13136 Fix Autoconf PR/209.
13137 Also reported by Frank Denis.
13139 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Don't over quote.
13141 2002-02-07 Akim Demaille <akim@epita.fr>
13143 Fix Autoconf PR/207:
13144 AC_PREFIX_PROGRAM fails with dashed program names
13146 * lib/autoconf/general.m4 (AC_PREFIX_PROGRAM): Just use a fresh
13147 variable when looking for the prefix program.
13148 Now it also works for shell variables.
13150 2002-02-07 Akim Demaille <akim@epita.fr>
13152 * doc/autoconf.texi (Limitations of Builtins): More about
13153 case/esac.

13157 * lib/autoconf/status.m4 (_AC_OUTPUT_COMMANDS): Don't output empty
13158 case/esac, some shells don't support it.
13159 Reported by Zack Weinberg.
13160 * tests/torture.at (AC_CONFIG_COMMANDS with empty commands): New.
13162 2002-02-06 Akim Demaille <akim@epita.fr>
13164 * lib/autotest/general.m4 (AT_INIT): When handling --keywords, be
13165 sure not to introduce newlines in at_groups.
13166 * lib/autotest/Makefile.am (autotest.m4f): Typo.
13168 2002-02-06 Akim Demaille <akim@epita.fr>
13170 * tests/torture.at (Configuring subdirectories): Skip if aclocal
13171 is not available.
13173 2002-02-05 Paul Eggert <eggert@twinsun.com>
13175 * doc/autoconf.texi (Specific Compiler Characteristics):
13176 Describe HP-UX cc bug workaround more accurately.
13177 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Cast to long,
13178 not unsigned long.
13179 * tests/semantics.at (AC_CHECK_SIZEOF): Check non-GCC
13180 cross-compilers, too. This undoes some of the most recent change
13181 to this file.
13183 2002-02-05 Akim Demaille <akim@epita.fr>
13185 * tests/Makefile.am (check_SCRIPTS): Use it, instead of WRAPPERS,
13186 to make sure they are up to date when `check' is run.

13190 * doc/autoconf.texi (Making testsuite Scripts): Document

13195 * lib/freeze.mk: New.
13197 2002-02-05 Akim Demaille <akim@epita.fr>
13199 Implement `autom4te --freeze'.
13201 * bin/autom4te.in (&freeze): New.
13202 * lib/autoconf/autoconf.m4, lib/autotest/general.m4,
13203 * lib/m4sugar/m4sh.m4: Don't include files given by autom4te.
13205 2002-02-05 Akim Demaille <akim@epita.fr>
13207 * bin/autom4te.in (&parse_args): Implement `frozen files are
13208 optional are the sum of the previous files on the command line'.
13209 Also, pass `--reload-state=' on them, so...
13210 (handle_m4): don't.
13211 * lib/autom4te.in (Autotest, Autoconf): Rely on M4sh.
13212 (M4sh): Rely on M4sugar.
13213 (Autotest, M4sh, M4sugar): Use frozen files.
13215 2002-01-31 Akim Demaille <akim@epita.fr>
13217 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Accept $4.
13218 * doc/autoconf.texi (Initializing configure): Adjust.
13220 2002-01-30 Akim Demaille <akim@epita.fr>
13222 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Map non
13223 alphanumeric to `-' instead of `_'.
13225 2002-01-30 Akim Demaille <akim@epita.fr>
13227 * tests/semantics.at (AC_CHECK_SIZEOF): Split into two tests: one
13228 for plain code, the other for cross-compilation code. The latter
13229 is now run with GCC only.
13230 * doc/autoconf.texi (Compilers and Preprocessors): New.
13232 2002-01-30 Akim Demaille <akim@epita.fr>
13234 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Support pre-defined
13235 values.
13236 * doc/autoconf.texi (Initializing configure): Explain how to
13237 change AC_INIT default values.
13239 2002-01-29 Akim Demaille <akim@epita.fr>
13241 * tests/torture.at (Configuring subdirectories): Use configure.in,
13242 so that aclocal 1.4 works.
13243 Reported by Alexandre Duret-Lutz and Larry Schmitt.
13245 2002-01-28 Akim Demaille <akim@epita.fr>
13247 * doc/autoconf.texi (Writing testsuite.at): AT_CLEANUP no longer
13248 needs an argument.
13250 2002-01-28 Akim Demaille <akim@epita.fr>
13252 * lib/autotest/general.m4 (AT_INIT): Don't be ridiculous: adjust
13253 AUTOTEST_PATH *after* it was set.
13254 Don't put `.' in the PATH: the user should be precise and `./' if
13255 needed. In addition, given that the test suite does some `cd', if
13256 `.' is in the path, the `tested programs' sections will report
13257 programs found in the test suite's directory, while during the
13258 tests (performed in their own directory), these programs are no
13259 longer visible. In other words, the results is confusing and
13260 useless.
13261 * tests/m4sh.at: Adjust: don't rely on `.' being in the PATH.
13263 2002-01-24 Akim Demaille <akim@epita.fr>

13272 2002-01-24 Akim Demaille <akim@epita.fr>
13274 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Use PATH_SEPARATOR.
13275 (_AS_PATH_SEPARATOR_PREPARE): Don't expect $SHELL to be
13276 Bourne. Use /bin/sh.
13277 From Andreas Buening.
13279 2002-01-24 Akim Demaille <akim@epita.fr>
13281 * config/config.guess, config/config.sub, config/texinfo.tex:

13291 Automake.
13293 2002-01-24 Akim Demaille <akim@epita.fr>
13295 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS)
13296 (_AC_INIT_PREPARE): Support -n as --no-create, as documented.
13297 Reported by Geir Ove Myhr.
13299 2002-01-21 Akim Demaille <akim@epita.fr>

13303 2002-01-21 Akim Demaille <akim@epita.fr>
13305 * lib/Autom4te/General.pm (getopt): Use a more GNUish error
13306 message on invalid options.
13307 * bin/autom4te.in (parse_args): Don't use
13308 Autoconf::General::getopt with non valid options.
13310 2002-01-17 Jim Meyering <meyering@lucent.com>
13312 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Initialize
13313 $ac_cv_exeext so we don't use an old, invalid, cached value.
13315 2002-01-11 Akim Demaille <akim@epita.fr>
13317 * lib/autoconf/functions.m4 (AC_FUNC_STRNLEN): New, from Jim
13318 Meyering.

13320 limitation.

13324 2002-01-06 Akim Demaille <akim@epita.fr>
13326 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Don't create
13327 package.m4, since is really depends upon configure.ac, not
13328 configure.
13329 * doc/autoconf.texi (testsuite Scripts): Adjust.
13330 * tests/Makefile.am (package.m4): New.
13331 EXTRA_DIST it since its a source.
13333 2002-01-06 Akim Demaille <akim@epita.fr>
13335 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Move the AC_SUBST
13336 of PACKAGE_NAME, PACKAGE_TARNAME, PACKAGE_VERSION, PACKAGE_STRING,
13337 and PACKAGE_BUGREPORT from here...
13338 (_AC_INIT_DEFAULTS): to here, since it is unrelated to the
13339 arguments.
13340 (_AC_INIT_PREPARE): AC_DEFINE these symbols.
13341 * lib/autotest/general.m4: Use AT_PACKAGE_*, not PACKAGE_*.
13342 (AT_INIT): No longer catch `^PACKAGE_(BUGREPORT|STRING)$'.
13343 * tests/tools.at (autoheader): Adjust.
13344 * tests/atspecific.m4 (AT_CHECK_DEFINES): Adjust.

13359 sometimes needing writable input.
13361 2001-12-17 Jim Meyering <meyering@lucent.com>
13363 * doc/autoconf.texi (New Macros): Tweak wording.
13365 2001-12-14 Akim Demaille <akim@epita.fr>
13367 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): We cleaning up the
13368 trailing files, don't apply `-rf' to files which might not be
13369 created by configure (core, core.*, and *.core), but just `rm -f'.
13370 Suggested by Jonathan Kamens.
13372 2001-12-14 Aaron M. Ucko <amu@alum.mit.edu>
13374 * lib/autoconf/general.m4: Avoid duplicates in `$ac_configure_args'.

13387 * tests/atspecific.m4, tests/autoreconf.in, tests/tools.at,
13388 * tests/wrappl.in, tests/wrapsh.in: Adjust.
13390 2001-12-12 Steven G. Johnson <stevenj@alum.mit.edu>
13392 * lib/autoconf/fortran.m4 (_AC_PROG_F77_V_OUTPUT): Fix failed
13393 C/Fortran linking on HP/UX, by extracting the Fortran library
13394 search path from the LPATH line in the $F77 -v output.
13396 2001-12-12 Kevin Ryde <user42@zip.com.au>
13398 * doc/autoconf.texi (File Descriptors): Use a clearer layout for the
13399 forbidden file descriptors table.
13401 2001-11-26 Akim Demaille <akim@epita.fr>
13403 * bin/autoscan.in (%c_keywords): Build it at top level.
13404 Map to 1 in order to simplify its uses.
13406 2001-11-26 Akim Demaille <akim@epita.fr>
13408 * bin/autoscan.in (&scan_c_file, &scan_sh_file, &scan_makefile):
13409 Remove $filepath, useless.
13410 (&scan_makefile): Don't remove the $(FOO), ${FOO} and @FOO@
13411 variables, they are really part of the tokens.
13412 Split the input line on spaces and then look for tokens.
13413 Now autoscan ceases to ask for AC_PROG_LEX for the package Bison
13414 because of `lex$U.$(OBJEXT)'.
13415 (&scan_files): Use "@list" instead of join.
13416 * doc/Makefile.am (CLEANFILES): Add *.fns.
13418 2001-11-26 Akim Demaille <akim@epita.fr>
13420 * tests/autoreconf.in, tests/autom4te.in, tests/autoupdate.in:
13421 Remove, replaced by...
13422 * tests/wrappl.in: Be common for all the Perl executables.
13423 In particular autoscan and autoheader want -I.
13424 * configure.ac: Adjust.
13425 * lib/autoscan/headers: errno.h is portable.
13427 2001-11-26 Akim Demaille <akim@epita.fr>
13429 * bin/autoscan.in (used): New.
13430 Use it.
13432 2001-11-26 Akim Demaille <akim@epita.fr>
13434 * bin/autoscan.in (&scan_c_file): Better parsing of CPP
13435 directives.
13436 (&scan_sh_file): Remove a duplicate pattern.
13437 (&check_configure_ac): Use long options.
13438 * lib/autoscan/headers (alloca.h): Check with AC_FUNC_ALLOCA.
13440 2001-11-26 Akim Demaille <akim@epita.fr>
13442 * bin/autoscan.in (scan_c_file): Fix the handling of C comments.
13443 Before, having a line containing the opening of a multi line
13444 comment made the whole line be ignored.
13446 2001-11-26 Akim Demaille <akim@epita.fr>
13448 * doc/autoconf.texi (Using an Autotest Test Suite): New.
13449 (testsuite Scripts): Be one of its subsection.
13450 (Autotest Logs): New.
13452 2001-11-26 Akim Demaille <akim@epita.fr>
13454 Test groups are now run two directories deeper.
13456 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Replace srcdir,
13457 top_srcdir and top_builddir with at_srcdir, at_top_srcdir and
13458 at_top_builddir.
13459 * lib/autotest/general.m4 (AT_INIT): Compute srcdir,
13460 top_srcdir, builddir and top_builddir.
13461 Use `at_*dir' relatively to the directory containing the
13462 suite, use `*dir' when relatively to the current group dir.
13464 2001-11-25 Joseph S. Myers <jsm28@cam.ac.uk>
13466 * doc/autoconf.texi, TODO, lib/autoconf/fortran.m4,
13467 lib/autoconf/functions.m4, lib/autoconf/headers.m4,
13468 tests/atgeneral.m4, tests/tools.at, tests/atspecific.m4: Fix
13469 spelling errors.
13471 2001-11-22 Alexandre Duret-Lutz <duret_g@epita.fr>
13473 * doc/autoconf.texi (Using System Type): Add an example of `case
13474 $host' usage so people quit using `case $target' everywhere.
13476 2001-11-22 Akim Demaille <akim@epita.fr>
13478 * doc/autoconf.texi (Installation Directory Variables): Englishoes
13479 spotted by Jim Meyering.
13481 2001-11-16 Paul Eggert <eggert@twinsun.com>
13483 This patch implements a `long double' suggestion by Oliver Kiddle.
13485 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C)): Make the array
13486 static, to catch errors if the value isn't known at compile-time
13487 and the compiler supports dynamic arrays. Change its name from
13488 `_array_' to `test_array' to avoid potential name clashes.
13489 (AC_C_LONG_DOUBLE): Make it a compile-time test, not a run-time
13490 test. Do not define HAVE_LONG_DOUBLE if `long double' is no
13491 better than double. Catch a bug in GCC 2.95.2 x86.
13492 * doc/autoconf.texi (C Compiler): Document the above.
13493 * NEWS: Likewise.
13495 2001-11-13 Akim Demaille <akim@epita.fr>
13497 * tests/m4sh.at (LINENO): Protect from autom4te's substitution by
13498 hand.
13499 * tests/tools.at: Don't protect dnl, AT_DATA_M4SH does.
13501 2001-11-13 Akim Demaille <akim@epita.fr>
13503 * lib/autotest/general.m4 (AT_INIT): After having run the test
13504 group, go back to the initial directory, not to at_suite_dir.
13506 2001-11-13 Akim Demaille <akim@epita.fr>
13508 * tests/atspecific.m4 (AT_DATA_M4SUGAR, AT_DATA_M4SH)
13509 (AT_DATA_AUTOCONF): Also protect @&t@ from autom4te.
13510 (AT_CHECK_AUTOCONF, AT_CHECK_AUTOHEADER): Pass no --include
13511 option.
13512 (AT_CHECK_CONFIGURE): Use absolute paths.
13513 (_AT_CHECK_AC_MACRO): Create aclocal.m4 with AC_STATE_SAVE in it.
13514 The problem is still the old one: there is no means in M4 (that I
13515 know about) to create a defining macro, because there is no means
13516 to create `$1' etc., therefore, the defining macro ``swallows''
13517 all the arguments meant to the defined macro.
13519 2001-11-13 Akim Demaille <akim@epita.fr>
13521 * tests/atspecific.m4 (AT_DATA_AUTOCONF): New.
13522 (AT_CONFIGURE_AC): Output the definition of AC_STATE_SAVE in
13523 configure.ac.
13524 * tests/aclocal.m4: Remove, as it is no longer used.
13526 2001-11-13 Akim Demaille <akim@epita.fr>
13528 * lib/autotest/general.m4: Change `tests?' into `groups?' in
13529 variable names when referring to a single test group, or to
13530 `suite' when referring to the whole test suite.
13531 `at_last_test' is removed: m4 compute at_format itself.
13532 (at_stdout, at_stder1, at_stderr): New variables.
13533 (AT_CHECK): Use them.
13535 2001-11-13 Akim Demaille <akim@epita.fr>
13537 * lib/autotest/general.m4 (AT_INIT): Be sure to put `.', relative,
13538 in PATH.
13539 Create `testsuite.dir/003/run' instead of `testsuite.003'.
13540 Do it as soon as a test fails, don't wait till the end of the test
13541 suite.
13542 Don't remove $as_me.[0-9]*, since these files no longer exist.
13544 2001-11-13 Akim Demaille <akim@epita.fr>
13546 * tests/tools.at: Use absolute paths, since we are no longer run
13547 in place.
13549 2001-11-13 Akim Demaille <akim@epita.fr>
13551 Now that tests are running in their own private dir, there is no
13552 need to list the files to remove at the end of tests groups.
13554 * lib/autotest/general.m4 (_AT_CLEANUP_FILE, AT_CLEANUP_FILES):
13555 (AT_data_files, at_data_files): Remove.
13556 (AT_CLEANUP, AT_DATA): Simplify.
13557 (AT_INIT): Adjust.
13558 Remove the group dir if !debug && !failed.
13559 * tests/atspecific.m4: Adjust.
13561 2001-11-13 Akim Demaille <akim@epita.fr>
13563 Start a new layout for Autotest: `testsuite' creates
13564 `testsuite.dir' in which the at-check-line etc. files are to be
13565 found, and `testsuite.dir/003' where the test group 3 is run.
13567 * lib/autotest/general.m4 (AT_INIT): at_tests_dir,
13568 at_check_line_file, at_format, at_test_normalized, at_group_dir
13569 are new variables.
13570 Create the directories.
13571 Use absolute paths for at- files.
13572 (AT_CHECK): Adjust.
13574 2001-11-11 Michael Matz <matz@kde.org>
13576 * m4sugar.m4 (_m4_foreach): Make it linear instead quadratic.
13577 (m4_car2): New.
13578 (m4_car): Properly quote arguments.
13580 2001-11-13 Akim Demaille <akim@epita.fr>
13582 * tests/aclocal.m4 (AC_STATE_SAVE): s/LIBOBJS/LIB@&t@OBJS/ to cope
13583 with stricter rules on LIBOBJS.
13585 2001-11-12 Paul Eggert <eggert@twinsun.com>
13587 * lib/autoconf/c.m4 (AC_C_PROTOTYPES): Define __PROTOTYPES too.
13588 * doc/autoconf.texi (C Compiler): AC_C_PROTOTYPES now defines
13589 __PROTOTYPES too.
13591 2001-11-12 Akim Demaille <akim@epita.fr>
13593 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT): Use AC_CHECK_FUNCS.
13595 2001-11-12 Akim Demaille <akim@epita.fr>
13597 * lib/autoconf/c.m4, lib/autoconf/fortran.m4,
13598 * lib/autoconf/functions.m4, lib/autoconf/general.m4,
13599 * lib/autoconf/headers.m4, lib/autoconf/libs.m4,
13600 * lib/autoconf/programs.m4, lib/autoconf/specific.m4,
13601 * lib/autoconf/types.m4: When invoking AC_DEFINE and friends,
13602 specify to what the macro should be defined (typically to 1).
13604 2001-11-12 Akim Demaille <akim@epita.fr>
13606 * lib/autoconf/functions.m4 (AC_FUNC_STRTOD): AC_SUBST POW_LIB.
13607 From Jim Meyering.
13609 2001-11-12 Akim Demaille <akim@epita.fr>
13611 * lib/autoconf/programs.m4 (_AC_PROG_LEX_YYTEXT_DECL): Use
13612 AC_TRY_EVAL to run $LEX, not AC_TRY_COMMAND. This validates the
13613 definition used by Automake where LEX is +/- "${missing} lex" and
13614 `missing' itself contains variables.
13616 2001-11-12 Akim Demaille <akim@epita.fr>
13618 * lib/autotest/general.m4 (AT_INIT): Push KILL at the end.
13619 Now that M4sh pushes BODY, the comments were output at the end of
13620 the test suites.
13622 2001-11-08 Akim Demaille <akim@epita.fr>
13624 * bin/autoreconf.in (&autoreconf): Run aclocal before tracing, so
13625 that we can trace macros from aclocal.m4.
13626 Trace AC_PROG_LIBTOOL, not AM_PROG_LIBTOOL, since the latter is
13627 obsoleted, and redirect to the former anyway.
13628 Reported by Ralf Corsepius.
13630 2001-11-08 Akim Demaille <akim@epita.fr>
13632 * bin/autoreconf.in (&autoreconf): AC_CONFIG_SUBIDRS are to be
13633 processed only if present.
13634 * tests/torture.at (Configuring subdirectories): Use autoreconf
13635 instead of successive calls to autoconf.
13636 Add a nonexistent subdirectory to exercise the patch above.
13637 Reported by Ralf Corsepius.
13639 2001-11-08 Kevin Ryde <user42@zip.com.au>
13641 * doc/autoconf.texi (Limitations of Usual Tools): Note HP-UX cc
13642 doesn't accept .S files.
13644 2001-11-07 Akim Demaille <akim@epita.fr>
13646 * lib/m4sugar/m4sugar.m4 (m4_pattern_forbid): Accepts $2.
13647 * lib/autoconf/general.m4 (AC_INTI): Forbid LIBOBJS.
13648 (_AC_LIBOBJ): s/LIBOBJS/LIB@&t@OBJS/.
13649 * bin/autom4te.in (warn_forbidden): New.
13650 (handle_output): Use it.
13651 Read m4_pattern_forbid with messages.
13653 2001-11-05 Akim Demaille <akim@epita.fr>
13655 * bin/autom4te.in (--normalize): Remove.
13656 * lib/autom4te.in: Adjust.
13658 2001-11-05 Akim Demaille <akim@epita.fr>
13660 * tests/Makefile.am (testsuite): Rename this target as...
13661 ($(TESTSUITE)): this.
13662 From Nicolas Joly.
13664 2001-11-05 Alexandre Duret-Lutz <duret_g@epita.fr>
13666 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): When removing
13667 the --prefix option, also remove it's argument.
13669 2001-11-05 Akim Demaille <akim@epita.fr>
13671 * doc/autoconf.texi (testsuite Invocation): Update.
13672 (Writing testsuite.at): Update.
13674 2001-11-03 Akim Demaille <akim@epita.fr>
13676 * doc/autoconf.texi: s/@code/@command/ where appropriate.
13678 2001-11-03 Akim Demaille <akim@epita.fr>
13680 * lib/Autom4te/General.pm: (&catfile, &canonfile)
13681 (&file_name_is_absolute): New, wrappers around routines from
13682 File::Spec.
13683 Use and export them.
13684 (&find_configure_ac): Optionally take a directory where to look at.
13685 * bin/autoreconf.in (&parse_args): Trim the configure.ac part of
13686 the arguments.
13687 Default @ARGV to `.', not find_configure_ac.
13688 (&autoreconf): Argument is a directory.
13689 Trace AC_CONFIG_SUBDIRS and schedule the subdirs for autoreconf'ing.
13690 * doc/autoconf.texi (autoreconf Invocation): Update.
13692 2001-11-03 Akim Demaille <akim@epita.fr>
13694 * lib/Autom4te/General.pm (@export_vars, @export_subs)
13695 (@export_forward_subs): New.
13696 Add basename, dirname, and fileparse.
13697 (@EXPORT): Adjust.
13698 * bin/autoreconf.in (&autoreconf): Fix call to fileparse.
13699 Don't look for aclocal flags if we already know aclocal is not
13700 used.
13701 Move aclocal.m4t only if it exists.
13702 Reported by Ezra Peisach.
13704 2001-11-03 Akim Demaille <akim@epita.fr>
13706 * bin/autoreconf.in (&parse_args): Work only on the configure.ac
13707 passed on command line, defaulting to ./configure.ac if present.
13708 (&maybe_autoreconf, File::Find): Remove, unused.
13709 (&autoreconf): If autoconf is not used, don't try to trace.
13711 2001-11-02 Akim Demaille <akim@epita.fr>
13713 * configure.ac: Bump to 2.52g.
13715 2001-11-02 Akim Demaille <akim@epita.fr>
13717 Version 2.52f.
13719 2001-11-02 Akim Demaille <akim@epita.fr>
13721 * config/config.guess, config/config.sub, doc/standards.texi:
13722 * config/lispdir.m4: Update from masters.
13723 * configure.ac: Bump to 2.52f.
13725 2001-11-02 Akim Demaille <akim@epita.fr>
13727 * bin/autoreconf.in (&autoreconf): Set `$aclocal_flags' to ''.
13728 Don't run aclocal when aclocal.m4 is not from aclocal.
13729 From Ezra Peisach.
13730 Don't run libtoolize and gettextize if --install is not given.
13732 2001-11-01 Paul Eggert <eggert@twinsun.com>
13734 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): _AS_CR_PREPARE needs to
13735 be invoked before _AS_LINENO_PREPARE.
13736 (_AS_LINENO_PREPARE): Use as_cr_digits and as_cr_alnum rather
13737 than character ranges.
13739 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Fix NLS before
13740 invoking AS_BASENAME. Set the locale variables to 'C' if
13741 possible, as POSIX requires this to get the traditional
13742 behavior.
13743 * doc/autoconf.texi (Special Shell Variables): Describe the above.
13745 2001-10-31 Paul Eggert <eggert@twinsun.com>
13747 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): Do not surround body
13748 with {}, as that triggers a bug in Bash 2.05.
13750 (_AS_LINENO_PREPARE): Use Sed rather than
13751 Awk. Fix the sed prepass to work even if there are multiple
13752 instances of $LINENO on the same line. Do not substitute for
13753 other variables like $LINENOT. Do not check file dates; such a
13754 check is unreliable on sufficiently fast machines, and removing
13755 the check makes the code simpler and more reliable. Check for
13756 output and chmod failures.
13758 * doc/autoconf.texi (Special Shell Variables): Document
13759 the above.
13761 2001-10-31 Akim Demaille <akim@epita.fr>
13763 * tests/Makefile.am (atconfig): Remove this target, Automake
13764 handles it now.
13766 2001-10-31 Akim Demaille <akim@epita.fr>
13768 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Do not
13769 AC_CONFIG_FILES(atlocal) as it means a file atlocal.in *must* be
13770 provided, while it is optional.
13771 * configure.ac: Adjust.
13773 2001-10-26 Paul Eggert <eggert@twinsun.com>
13775 * NEWS, README, configure.ac, lib/Autom4te/General.pm,
13776 lib/Autom4te/Struct.pm:
13777 Require Perl 5.005_03 instead of just 5.005, as some tests fail
13778 with 5.005_02.
13780 * doc/autoconf.texi (Special Shell Variables): Document some
13781 more LINENO gotchas, particularly with respect to the Awk+Sed hack.
13783 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): New macro.
13784 (_AS_LINENO_PREPARE): Use it instead of shell eval, since
13785 eval $LINENO is not portable in practice.
13787 2001-10-24 Akim Demaille <akim@epita.fr>
13789 * lib/Autom4te/General.pm (backname): New.
13791 2001-10-24 Akim Demaille <akim@epita.fr>
13793 * m4/: Remove, merged into...
13794 * config/: here.
13796 2001-10-23 Tim Van Holder <tim.van.holder@pandora.be>
13798 * doc/autoconf.texi (Shellology): Mention the problems with bash
13799 2.05's use of ANSI quoting in its `set' builtin.
13801 2001-10-22 Paul Eggert <eggert@twinsun.com>
13803 * lib/autoconf/functions.m4 (AC_FUNC_STRERROR_R):
13804 Rename ac_cv_func_strerror_r_works to ac_cv_func_strerror_r_char_p,
13805 and rename HAVE_WORKING_STRERROR_R to STRERROR_R_CHAR_P, since
13806 POSIX decided to standardize on the int flavor of strerror_r.
13807 Always do char* test, as there's no reason not to.
13808 Assign to a char* var, to catch strerror_r that returns int*.
13810 * doc/autoconf.texi (Particular Functions):
13811 Document the above changes. Also, document the fact that
13812 AC_FUNC_STRERROR_R defines HAVE_DECL_STRERROR_R.
13814 * NEWS: Mention HAVE_WORKING_STRERROR_R -> STRERROR_R_CHAR_P.
13816 2001-10-20 Akim Demaille <akim@epita.fr>
13818 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): The name of
13819 the executable was missing from the log.
13821 2001-10-20 Akim Demaille <akim@epita.fr>
13823 * lib/Autom4te/General.pm (&update_file): If destination is
13824 unchanged, remove the source.
13825 (&up_to_date_p): Don't be verbose, be debug.
13826 * bin/autoreconf.in: No longer support --m4dir.
13827 (&autoreconf): Display the full path of the configure.ac we are
13828 studying.
13829 Trace it only once.
13830 Be sure to honor --force with gettextize.
13831 Always run aclocal.
13832 * doc/autoconf.texi: Adjust.
13834 2001-10-20 Akim Demaille <akim@epita.fr>
13836 * bin/autoheader.in ($localdir, $m4, $SIMPLE_BACKUP_SUFFIX):
13837 Remove, dead.
13838 * bin/autoreconf.in (&autoreconf): Do not run gettextize when
13839 `intl' is already present, as it refuses unless --force.
13840 (&parse_args): Use -I, --include instead of the old Autoconf
13841 options.
13842 ($localdir, $autoconf_dir): Remove.
13843 (@include): New.
13844 (&maybe_autoreconf): New, to preserve $_ for File::Find.
13846 2001-10-19 Jens Petersen <petersen@redhat.com>
13848 * lib/autoconf/programs.m4 (AC_PROG_AWK): Prefer gawk to mawk.
13849 * doc/autoconf.texi (Particular Programs): Likewise.
13851 2001-10-19 Akim Demaille <akim@epita.fr>
13853 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Name the generated

13876 (AS_BASENAME_EXPR): New macro.
13877 (AS_BASENAME_SED): Do not assume GNU sed semantics.
13878 (AS_BASENAME): Use 'basename' if that works; then try 'expr';
13879 and fall back on 'sed' only if the other two fail. This makes
13880 AS_BASENAME act more like AS_DIRNAME.
13881 (as_me): Shell-quote the argument of AS_BASENAME, in case $0
13882 contains white space.
13883 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR):

14033 * tests/Makefile.am (clean-local): Don't invoke $(TESTSUITE) if it

14118 (_AC_COMPUTE_INT): Pass IF-FAILS arg to _AC_COMPUTE_INT_COMPILE.

14163 enough.

14302 PATH_SEPARATOR.
14303 (Special Shell Variables[PATH_SEPARATOR]): Ditto.
14304 (Special Shell Variables[CDPATH]): Mention that $PATH_SEPRATOR should
14305 be used instead of ':'.
14306 * lib/autotest/general.m4: Replace occurrences of ':' in
14307 AUTOTEST_PATH with $PATH_SEPARATOR at test suite startup.
14309 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
14311 * tests/atgeneral.m4: Add basic support for test ranges (e.g. 7-34) as
14312 arguments. Fixed a typo.
14314 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
14316 * man/Makefile.am (.x.1): Use @PATH_SEPARATOR@, not ':' to set up
14317 $PATH. Also set AUTOM4TE_CFG, so we can process autom4te properly.
14319 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
14321 * bin/autoscan.in: Add 'exec-perl-if-not-run-by-perl'.
14322 * bin/autoupdate.in: Ditto.
14323 * bin/autoheader.in: Reworded a few comments.
14324 * bin/autoconf.in: Reworded help text for a few options.
14325 * bin/autoheader.in, bin/autom4te.in, bin/autoreconf.in,
14326 * bin/autoscan.in, bin/autoupdate.in: Ditto.
14328 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
14330 * lib/Autom4te/XFile.pm (open): Simplified the error message (we
14331 already have $file). Set output files to binary mode (helps avoid
14332 CR issues on DOSish systems).
14334 2001-09-19 Akim Demaille <akim@epita.fr>
14336 * lib/autotest/general.m4: Englishoes.
14337 From Tim Van Holder and Alexey Mahotkin.
14339 2001-09-18 Paul Eggert <eggert@twinsun.com>
14341 * doc/autoconf.texi (Common Shell Constructs): New node,
14342 documenting AS_DIRNAME.
14343 (Limitations of Usual Tools): Refer to it when discussing dirname.
14344 Also, update discussion of POSIX standard to reflect latest draft.
14346 * lib/autoconf/c.m4:
14347 (AC_LANG_INT_SAVE(C)): Also support negative values, down to LONG_MIN.
14349 * lib/autoconf/general.m4 (_AC_COMPUTE_INT_COMPILE):
14350 Do not pass a first argument with leading '-'
14351 to expr, by parenthesizing initial integers that might be negative.
14353 * doc/autoconf.texi (Particular Functions): AC_FUNC_GETPGRP
14354 now merely checks whether it is an error to pass an argument
14355 to getpgrp.
14357 * lib/autoconf/functions.m4 (_AC_FUNC_GETPGRP_TEST): Remove.
14358 (AC_FUNC_GETPGRP): Don't bother with a runtime test. Just check
14359 whether it is a (compile-time) error to pass an argument to
14360 getpgrp. This simpler test supports the revised documentation,
14361 and is all that AC_FUNC_GETPGRP's users really need.
14363 2001-09-18 Akim Demaille <akim@epita.fr>
14365 * doc/autoconf.texi (Limitations of Make) <$<>: New.
14367 2001-09-18 Akim Demaille <akim@epita.fr>
14369 * doc/autoconf.texi (Limitations of Usual Tools) <find>: More about
14370 `{}'.
14371 * lib/autotest/general.m4 (AT_INIT): Adjust.
14373 2001-09-18 Paul Wagland <paul@wagland.net>
14375 * tests/m4sh.at: Ensure that AS_DIRNAME handles '/', '//' and '///'
14376 correctly.
14377 Add test for AS_BASENAME.
14378 * lib/m4sugar/m4sh.m4: Fix AS_BASENAME so that it passes the previous
14379 added test. It now correctly handles /1/2/3/, returning '3' not ''.
14380 Added AS_BASENAME_SED to make the interface the same as AS_DIRNAME.
14381 * tests/base.at: Fixed the expected responses. The old ones were
14382 one line out...
14383 * lib/autoconf/general.m4: Fixed AC_PREFIX_PROGRAM, it now behaves as
14384 the documentation claims it should (and how it behaved in 2.13).
14386 2001-09-18 Akim Demaille <akim@epita.fr>
14388 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): No INIT-CMDS in
14389 the AC_CONFIG_COMMANDS invocation.
14390 This also solves the name clash problems.
14391 Don't set the package's ID.
14392 * lib/m4sugar/Makefile.am (version.m4): Revamp.
14393 No longer to be shipped.
14394 (version.in): Remove.
14395 * lib/m4sugar/m4sugar.m4, lib/autoconf/general.m4,
14396 * lib/autoconf/status.m4: Adjust.
14397 Use `m4_PACKAGE_STRING'.
14398 * lib/autotest/general.m4 (AT_INIT): N-th signature change: now
14399 the only optional argument is the name of the test suite.
14400 Expect `package.m4' to define the package signature.
14401 * lib/autom4te.in (Autotest): Add `package.m4?'.
14402 * tests/Makefile.am (package.m4): New.
14403 * tests/suite.at: ifnames is a victim.
14405 2001-09-18 Akim Demaille <akim@epita.fr>
14407 * lib/autom4te.in (Autoconf): Preselect AM_CONDITIONAL,
14408 AC_LIBSOURCE, AC_CONFIG_FILES.
14409 * lib/autotest/general.m4 (AT_INIT): Don't abort when a tested
14410 program version string doesn't match the package's.
14411 * lib/autoconf/general.m4 (AC_CACHE_VAL): Reestablish the space
14412 after `(cached)'.
14414 2001-09-17 Paul Eggert <eggert@twinsun.com>
14416 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):
14417 Allow expression to return any value that can fit into unsigned long
14418 (not int, as before). Check for output errors.
14420 2001-09-17 Bruno Haible <haible@ilog.fr>
14422 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):
14423 Always include <stdio.h> and <stdlib.h>. Evaluate
14424 the expression in an extra function before these includes. Call
14425 fprintf "%d" only after ensuring the argument is of type 'int'.
14426 Reported by Wayne Chapeskie <waynec@spinnaker.com>.
14428 2001-09-17 Paul Eggert <eggert@twinsun.com>
14430 Fix bug reported by Paul Townsend on AIX 4.3.3.0 with CFLAGS=-O4
14431 or CFLAGS=-O5. In that case, the linker has a relaxed view of
14432 fatal errors, and AC_CHECK_LIB causes it to include libraries even
14433 when they don't exist.
14435 * lib/autoconf/headers.m4 (AC_HEADER_DIRENT): Use AC_SEARCH_LIBS,
14436 not AC_CHECK_LIB, so that we don't use -ldir or -lx if we don't
14437 need it.
14439 * lib/autoconf/specific.m4 (AC_ISC_POSIX): Replace the old, crufty
14440 version with the version used by fileutils 4.1, except use
14441 AC_SEARCH_LIBS, not AC_CHECK_LIB, so that we don't use -lcposix if
14442 we don't need it.
14444 * doc/autoconf.texi (AC_ISC_POSIX): Describe new behavior.
14446 2001-09-13 Akim Demaille <akim@epita.fr>
14448 * tests/base.at, tests/m4sh.at: Be sure to issue the bangshe line
14449 _first_.
14450 Reported by Gerrit P. Haase.
14452 2001-09-13 Akim Demaille <akim@epita.fr>
14454 * lib/autotest/general.m4 (AT_INIT): Reset `AT_victims' so that
14455 m4_defn'ing is valid.

14461 Use it.

14474 * lib/autotest/general.m4 (AT_INIT): Rename AT_TESTS_ALL as
14475 AT_tests_all for consistency.
14476 Set at_victims.
14477 (AT_VICTIMS): Similar to AT_KEYWORDS.
14478 (_AT_CLEANUP_FILE_IF): Use m4_match and m4_re_escape.
14480 2001-09-13 Akim Demaille <akim@epita.fr>
14482 * lib/autotest/general.m4 (AT_INIT): Fix stupid bugs.
14484 2001-09-13 Akim Demaille <akim@epita.fr>
14486 * lib/autotest/general.m4 (AT_INIT): Create and remove
14487 `$as_me.[0-9]+' instead of `debug-[0-9]+.sh', so that multiple
14488 test suites can cohabit.
14490 2001-09-13 Akim Demaille <akim@epita.fr>
14492 * tests/mktests.sh: Don't output banners for empty test files.
14494 2001-09-13 Akim Demaille <akim@epita.fr>
14496 Test suites can be run independently of configure.

14542 2001-09-10 Akim Demaille <akim@epita.fr>
14544 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Don't pass

14598 2001-09-05 Akim Demaille <akim@epita.fr>

14601 the maintainer is dumb enough to do that...
14603 * lib/autotest/general.m4 (AT_SETUP, AT_LINE): Demonstrates your
14604 excellence in M4 quotation: consider `__file__' is active.

14637 New, extracted from main.
14638 Use IO::File wherever possible.
14639 (input.m4): Be constant, use -I instead of hard coding $tmp.

14641 Don't invoke `_au_disable', since ac was not loaded, but just
14642 `unm4.m4'.
14644 2001-08-31 Akim Demaille <akim@epita.fr>

14671 * doc/autoconf.texi (Quadrigraphs): Document `@&t@'.
14672 (testsuite Scripts): There is no such thing as `atconfig.in'.

14677 * lib/Autom4te/General.pm (&find_file): Browse the includes in the

14688 autom4te_perllibdir.
14690 2001-08-31 Akim Demaille <akim@epita.fr>
14692 * lib/autotest/general.m4 (AT_INIT): Don't pass all the args to

14698 * bin/autom4te.in (&parse_args): Strip `.' from `@include'.

14725 * tests/tools.at (Syntax of the Perl scripts): Pass the lib dir.
14726 (autoheader): Pass --force since the test suite goes too fast for
14727 the time stamps.

14755 Map --localdir, --autoconf-dir onto it.
14756 Forward autom4te's options instead of interpreting them.
14757 * bin/autoconf.in, bin/autoheader.in (AC_MACRODIR, autoconf_dir):
14758 There is no such envvar since the inception of autom4te.cfg.
14759 * bin/autom4te.in (&parse_args): Uniquify `@include'.
14760 * bin/autoupdate.in: Adjust, and perform more control.
14761 * tests/atspecific.m4 (AT_CHECK_AUTOCONF): Adjust.
14762 * tests/autoconf: Dittowise.
14764 2001-08-31 Akim Demaille <akim@epita.fr>
14766 * bin/autoconf.in: Don't bother with `acsite.m4' and `aclocal.m4'.
14767 * bin/autom4te.in (&find_file): Support `FILE?' standing for
14768 optionally `FILE'.
14769 Use -e, not -f, since /dev/null for instance is OK.
14770 (&parse_args): Adjust.
14771 * lib/autom4te.in (Autoconf): Add `acsite.m4?' and `aclocal.m4?'.
14773 2001-08-31 Akim Demaille <akim@epita.fr>
14775 * configure.ac: Also find tested executables in bin.
14776 * bin/autoconf.in, bin/autoheader.in, bin/autoreconf.in,
14777 * bin/autoscan.in, autoupdate.in: Use exclusively the name of the
14778 installed peer executables, only PATH is allowed to resolve it.
14779 Pass `autoconf_dir' via options, not via invisible envvars.
14780 * lib/Autom4te/General.pm (&find_peer): Remove.
14781 * lib/autotest/general.m4 (AT_INIT): `AUTOTEST_PATH=a:b' gives
14782 `abuild:asrc:bbuild:bsrc', not `abuild:bbuild:asrc:bsrc'.
14783 * man/Makefile.am: Let help2man rely on PATH instead of trying to
14784 find the executables for it.
14785 * tests/Makefile.am: Major cleanup. Too lazy to document...
14786 * tests/atlocal.in: Remove all the obscure envvar manipulations.
14787 We only need PERL.
14788 * tests/atspecific.m4, tests/tools.at: Passing --localdir is
14789 indeed related to running the test suite, while passing
14790 --autoconf-dir and others is related to running non installed
14791 Autoconf executables. So don't do that, leave it to...
14792 * tests/autoconf, tests/autoheader, tests/autom4te, tests/autoupdate,
14793 * tests/autoscan: New.
14794 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): Don't
14795 refer to library files: rely on --language.
14797 2001-08-29 Akim Demaille <akim@epita.fr>
14799 * bin/autom4te.in, lib/autom4te.in, bin/autoconf.in:
14800 s/--set/--language/.
14802 2001-08-29 Akim Demaille <akim@epita.fr>
14804 * doc/autoconf.texi: Strip the @nodes.
14805 Suggested by Paul Eggert.
14806 (Initializing configure): Typo.
14808 2001-08-29 Akim Demaille <akim@epita.fr>
14810 * bin/autom4te.in (&handle_output): s/@__@/@&t@/.
14811 Suggested by Paul Eggert.
14813 2001-08-29 Akim Demaille <akim@epita.fr>
14815 * Makefile.maint (do-po-update): Wget refuses to overwrite files:
14816 download in a tmp dir.
14818 2001-08-29 Akim Demaille <akim@epita.fr>
14820 * lib/autotest/general.m4: s/AT-devnull/devnull/ since there are
14821 case insensitive OSes out there :(
14822 From Tim Van Holder.
14824 2001-08-29 Akim Demaille <akim@epita.fr>
14826 * lib/autom4te.in: New.

14829 Rely on `AC_MACRODIR' in addition of `autom4te_perllibdir'.
14830 (&load_configuration): New. Use it.
14831 (&parse_args): Support --mode, --set, and --melt.
14832 * bin/autoconf.in: Simplify and adjust.
14833 * tests/Makefile.am (AUTOMAKE): Use --set.
14834 * tests/atlocal.in: Adjust.
14835 * BUGS: distcheck and check are weak.
14837 2001-08-29 Akim Demaille <akim@epita.fr>
14839 * lib/autotest/general.m4: Use
14840 foo=`(command) 2>/dev/null`
14841 not
14842 foo=`command` 2>/dev/null
14843 (at-devnull): Rename as...
14844 (AT-devnull): this.
14845 (--clean): Remove AT-* files too.
14846 * doc/autoconf.texi (Limitations of Usual Tools): Document `date'.
14847 Reported by Nicolas Joly.

14861 * lib/autotest/general.m4: Reword some messages.
14862 (AT_INIT): Check for the `times' builtin before using it.
14863 Support test ranges as arguments to the testsuite.
14864 Have -e imply -d as the help text suggested.
14866 2001-08-27 Akim Demaille <akim@epita.fr>
14868 * Makefile.maint: Formatting changes.
14869 (do-po-update, po-update, cvs-update, update): New targets.

14881 * lib/autotest/general.m4 (AT_INIT): Log the command line.
14882 Support `VAR=VAL' as arguments.
14883 Compute PATH _after_ the options processing, so that AUTOTEST_PATH
14884 may be set via the command line.
14886 2001-08-27 Akim Demaille <akim@epita.fr>
14888 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): $2 defaults to $1.
14889 * lib/autotest/autotest.m4 (AT_INIT): Expand AUTOTEST_PATH into
14890 first the build dirs, then the src dirs.

14893 2001-08-27 Akim Demaille <akim@epita.fr>
14895 * lib/autotest/general.m4 (AT_INIT): Output the definition of
14896 at_data_files earlier.
14897 (--clean, -c): New option.
14898 * tests/Makefile.am: Use this option.
14900 2001-08-27 Akim Demaille <akim@epita.fr>
14902 * lib/autoconf/status.m4 (_AC_SRCPATHS): Rename `ac_dots' as
14903 `ac_top_builddir' to mimic Automake's vocabulary, which much more
14904 readable.
14905 Adjust callers.
14906 * doc/autoconf.texi (Configuration Actions): Document the vars
14907 available in commands.
14908 Emphasize the risks of collisions in init-cmds.
14910 2001-08-27 Akim Demaille <akim@epita.fr>
14912 * doc/autoconf.texi (Input) <AC_INIT>: Move to..
14913 (Initializing configure): this new node.
14915 2001-08-27 Akim Demaille <akim@epita.fr>

14938 * lib/autoconf/status.m4 (_AC_SRCPATHS): New.
14939 (_AC_OUTPUT_LINKS, _AC_OUTPUT_FILES, _AC_OUTPUT_SUBDIRS): Use it.
14940 Standardize the var names (ac_sub_srcdir -> ac_srcdir, ac_subdir
14941 -> ac_dir).
14942 (_AC_OUTPUT_HEADERS): AS_DIRNAME always return a dir name.
14943 * lib/autoconf/general.m4 (_AC_INIT_HELP): Ditto.
14945 2001-08-27 Akim Demaille <akim@epita.fr>

14971 (AMTAR): Help automake define it.
14972 (INSTALL, install-data-hook): The INSTALL.txt trick is no longer
14973 needed, 1.5 can have a macro and a target with the same name.
14974 * m4/auxdir.m4, m4/cond.m4, m4/depend.m4, m4/install-sh.m4,
14975 * m4/strip.m4: New.

14988 * lib/m4sugar/m4sugar.m4 (m4_acversion, m4_version_prereq): New.
14989 Adjust callers.
14990 * bin/autoupdate.in: Distinguish M4sugar vs. Autoconf macros by
14991 the name of the directory they're in, instead of the filename,
14992 since version.m4 is now in m4sugar, but m4_acversion must not be
14993 classified as an Autoconf macro.
14994 ($input_m4): Don't qualify the path to m4sugar.
14995 Rather, pass autoconf_dir to m4.
14996 * tests/Makefile.am (testsuite): Remove -I top_srcdir, unneeded.

14999 2001-08-27 Akim Demaille <akim@epita.fr>

15011 of config.log on traps.
15012 (_AC_OUTPUT_CONFIG_STATUS): Use AS_BOX.
15013 Use consistently `_ACEOF' for configure's here docs, and `_CSEOF'
15014 for config.status'.
15015 Open the log as soon as possible.
15016 Use the same log introduction as configure's.
15018 2001-08-22 Paul Eggert <eggert@twinsun.com>
15020 * doc/autoconf.texi (Indices): New node.
15021 Move indices out of the top level menu and into this submenu.
15023 2001-08-22 Akim Demaille <akim@epita.fr>
15025 * lib/autoconf/programs.m4 (_AC_PROG_LEX_YYTEXT_DECL): Use
15026 AC_TRY_COMMAND.

15074 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Prepare the cross-compile
15075 program with AC_LANG_PROGRAM before feeding it to
15076 AC_COMPILE_IFELSE. Cleanup grep usage.
15078 2001-08-20 Akim Demaille <akim@epita.fr>
15080 * ChangeLog, ChangeLog.0, ChangeLog.1, ChangeLog.2, AUTHORS, BUGS,
15081 * NEWS, README, README-alpha, TODO, tests/README: This package is
15082 `Autoconf', not `autoconf' (the executable).
15084 2001-08-20 Akim Demaille <akim@epita.fr>
15086 Info readers seem to need `Index' in the index node title :(
15088 * doc/autoconf.texi: Reverse the 2001-08-15 change which
15089 simplified index node names.
15091 2001-08-20 Akim Demaille <akim@epita.fr>
15093 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Warn if the
15094 arguments are not literals.

15096 Specify the output variables, and macros defined.
15098 2001-08-20 Akim Demaille <akim@epita.fr>
15100 * doc/autoconf.texi (Examining Declarations) <AC_TRY_CPP>:
15101 (Examining Syntax) <AC_TRY_COMPILE>

15105 Reported by Werner Lemberg.
15107 2001-08-20 Akim Demaille <akim@epita.fr>

15133 2001-08-20 Akim Demaille <akim@epita.fr>
15135 Huh!?!?! There are still some user EOF tags used, which prevents
15136 their use in AC_CONFIG_COMMANDS for instance...
15138 * lib/autoconf/general.m4, lib/autoconf/specific.m4,
15139 * lib/autotest/general.m4: Rename the EOF tags as `_ACEOF',
15140 `_CSEOF', or `_ATEOF', as appropriate.
15141 * lib/m4sugar/Makefile.am, lib/autoconf/Makefile.am,
15142 * lib/autotest/Makefile.am (check-local): Enforce this constraint.

15202 * lib/autotest/general.m4 (AT_INIT): Refer to `$as_me.log', not

15220 * doc/autoconf.texi: Work around Texinfo buglets.

15267 value.

15275 (cvs-dist): depends upon it.
15277 2001-08-15 Tim Van Holder <tim.van.holder@pandora.be>
15279 * tests/Makefile.am: Use a clean-local rule to remove
15280 autom4te.cache (it's a directory, not a file.
15281 * Makefile.am: Ditto (but maintainer-clean-local).
15283 2001-08-15 Akim Demaille <akim@epita.fr>
15285 * bin/autom4te.in (@m4_warning): New.
15286 (&handle_m4): Use it.
15287 * tests/m4sugar.at (m4_warn): Pass `-f' to autom4te to ensure the
15288 warnings are issued at each run.
15289 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): M4sugar
15290 is in the src tree.
15292 2001-08-15 Akim Demaille <akim@epita.fr>
15294 * tests/atspecific.m4 (AT_CHECK_AUTOUPDATE): Perl is now required:
15295 don't waste time running `autoupdate --version' works.
15296 * tests/tools.at (autoupdating AC_PREREQ): Likewise.
15298 2001-08-13 Akim Demaille <akim@epita.fr>
15300 * doc/autoconf.texi (ma): Rename this index as...

15357 2001-08-11 Alexandre Duret-Lutz <duret_g@epita.fr>
15359 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Handle ACTION-IF-TRUE,
15360 ACTION-IF-FALSE, and ACTION-IF-UNKNOWN.
15361 * doc/autoconf.texi (C Compiler Characteristics): Update
15362 documentation for AC_C_BIGENDIAN.
15364 2001-08-11 Alexandre Duret-Lutz <duret_g@epita.fr>
15366 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Guess endianness by grep'ing
15367 magic values from an object file when cross-compiling.
15368 Based on code by Guido Draheim <Guido.Draheim@gmx.de>.
15370 2001-08-10 Akim Demaille <akim@epita.fr>
15372 * bin/autom4te.in (&handle_output): Don't use `grep' with side
15373 effects.
15374 Suggested by Russ Allbery.
15376 2001-08-10 Ralf Corsepius <corsepiu@faw.uni-ulm.de>
15378 * lib/autoconf/general.m4 (_AC_OUTPUT_SUBDIRS): Propagate the
15379 current $prefix to the sub-configures.
15381 2001-08-09 Tim Van Holder <tim.van.holder@pandora.be>
15383 * lib/autoconf/lang.m4: Ignore *.xSYM when looking for an executable
15384 extension (needed on BeOS). Reported by Guido van Rossum.
15386 2001-08-09 Akim Demaille <akim@epita.fr>
15388 * bin/autom4te.in ($icache): Load it only if older than autom4te.
15390 2001-08-07 Akim Demaille <akim@epita.fr>
15392 * lib/autotest/general.m4 (AT_INIT): All the `at-*' are to be
15393 removed.
15394 (at-setup-line): Huh? Be a variable `at_setup_line', not a file.
15395 No need to remove the files before and after the each test, before
15396 each test and at the end of the suite is enough.
15397 Display only the children `times', not the shell's.
15398 If the test failed or was skipped, at-times is not available.
15400 2001-08-07 Akim Demaille <akim@epita.fr>
15402 Always produce testsuite.log, including when there are no
15403 failures. This helps getting information on skipped tests, and
15404 duration of the tests. Err, implement the latter btw.
15406 * lib/autotest/general.m4 (AT_INIT): Set up fd 6 for the log.
15407 Dump information on the first run of each test.
15408 (AT_CLEANUP): Create `at-times' containing the duration of the
15409 test group.
15411 2001-08-07 Akim Demaille <akim@epita.fr>
15413 The use of `dumpstat' revealed that `len' was used although it
15414 should not. m4_text_wrap was using it, but in the Autoconf world
15415 where it is legal. Hence (i) test M4sh in its own world, not
15416 Autoconf's, and (ii), ahem, fix the bug :)
15418 * lib/autotest/general.m4: Be sure the set good quotes, as tracing
15419 does not like `' instead of [].
15420 (AT_INIT): Forbid `^_?AT_'.
15421 And don't output such tokens.
15422 * tests/Makefile.am (CLEANFILES): Add `script', `script.s4g',
15423 `script.as', and `autom4te.cache'.
15424 Remove `empty' and `macro' which are no longer used.
15425 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): New.
15426 * tests/m4sugar.at: Use it.
15427 * lib/m4sugar/m4sugar.m4: Use `m4_len' not `len'.
15429 2001-08-07 Akim Demaille <akim@epita.fr>
15431 * bin/autoconf.in, bin/autoheader.in: --force, -f is a new option.
15433 2001-08-07 Alexandre Duret-Lutz <duret_g@epita.fr>
15435 * bin/autom4te.in (handle_output): Typo in quadrigraph substitution.
15437 2001-08-04 Akim Demaille <akim@epita.fr>
15439 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA, AC_FUNC_ERROR_AT_LINE)
15440 (AC_FUNC_FSEEKO, AC_FUNC_OBSTACK): Use AC_LANG_IFELSE, not
15441 AC_TRY_LINK.
15442 * lib/autoconf/headers.m4 (AC_HEADER_MAJOR): Likewise.
15443 * lib/autoconf/fortran.m4 (_AC_LANG_PROGRAM_C_F77_HOOKS)
15444 (AC_F77_MAIN): Likewise.
15446 2001-08-04 Akim Demaille <akim@epita.fr>
15448 Don't rely on M4sugar outputting the patterns in files, since we
15449 might process the output _without_ running m4, hence without these
15450 files.
15452 * lib/m4sugar/m4sugar.m4 (m4_init): No need for `m4_tmpdir'.
15453 * bin/autom4te.in (@Request::includes): Remove, unused.
15454 (@Request::source): Rename as...
15455 (@Request::input): this.
15456 (@preselect): Add `m4_pattern_forbid' and `m4_pattern_allow'.
15457 (&handle_output): Fetch the patterns from the traces.
15458 `$forbidden' and `$allowed' are constant: use m//o.
15459 (&handle_m4): M4sugar no longer wants `m4_tmpdir'.
15460 (m4_pattern_forbid, m4_pattern_allow): Adjust for tracing only.
15462 2001-08-04 Akim Demaille <akim@epita.fr>
15464 `autoconf && autoheader' is sped up. Now, speed up `autoheader &&
15465 autoconf', i.e., in addition to caching traces, cache the output.
15467 * bin/autom4te.in (Request::cache): Rename as...
15468 (Request::id): this.
15469 ($cache, $icache, $tcache, $ocache): New.
15470 (&handle_m4): Save M4 output in the cache instead of $tmp.
15471 (&handle_output): Adjust.
15472 (&up_to_date_p): Check that the output cache is up to date too.
15473 (top level): Run `&handle_m4' iff force or the cache is invalid.
15474 Run `&handle_output' if the output cache is more recent.
15476 2001-08-04 Akim Demaille <akim@epita.fr>
15478 * bin/autom4te.in ($force): New.
15479 (&parse_args, &print_usage): -f, --force is a new option.
15480 (&handle_output): CPP directives might have spaces after `#'.
15481 (&parse_args): The first file only can be frozen.
15483 2001-08-04 Akim Demaille <akim@epita.fr>
15485 Don't let autom4te compute the `include' traces several times:
15486 first check that the trace cache file is up to date, and then
15487 compare its timestamp with that of the output.
15489 * bin/autom4te.in, bin/autoupdate.in, bin/autoscan.in: Normalize
15490 the preamble. Don't require 5.005 as Autom4te::General does it,
15491 and better yet (use `use', not `require'!).
15492 * lib/Autom4te/Struct.pm: Rename the last occurrences of
15493 Class::Struct as Autom4te::Struct.
15494 * lib/Autom4te/General.pm (File::stat): Use it.
15495 (&mtime): New, export it.
15496 * bin/autom4te.in: Use it.
15497 Declare `$req' is invalid if it is outdated.
15498 Don't declare it valid before saving it if something went wrong.
15500 2001-08-04 Akim Demaille <akim@epita.fr>
15502 Autom4te shall not encode Autoconf data, and preselecting traces
15503 must be proposed to the users.
15505 * bin/autom4te.in (@required_trace): Remove.
15506 (@preselect): New.
15507 (&parse_args, &print_usage): -p, --preselect is a new option.
15508 (&up_to_date_p): Adjust.
15509 * bin/autoconf.in: Preselect some Autoconf macros.
15511 2001-08-04 Akim Demaille <akim@epita.fr>
15513 * tests/tools.at (autoconf --trace: user macros): Check traces on
15514 macros invoked without arguments, and macros invoked with multiple
15515 lines arguments.
15517 2001-08-03 Alexandre Duret-Lutz <duret_g@epita.fr>
15519 * bin/autom4te.in (handle_traces): Fix rewriting of traces without
15520 arguments.
15522 2001-08-03 Akim Demaille <akim@epita.fr>
15524 * bin/autoconf.in ($@): Work around the usual sh bug.
15525 From Nicolas Joly.
15527 2001-08-03 Akim Demaille <akim@epita.fr>
15529 Clean up the handling of the M4 builtins tracing exception.
15531 * bin/autom4te.in (Request::request): Don't complete M4 builtins
15532 trace requests.
15533 (@m4_builtins): Rename as...
15534 (@m4_builtin): this.
15535 (%m4_builtin_alternate_name): New.
15536 (&parse_args): Complete the trace requests with alternate names.
15537 (&handle_traces): Hence no longer do it here.
15538 (&trace_requests): Remove, unused.
15540 2001-08-03 Akim Demaille <akim@epita.fr>
15542 * doc/autoconf.texi (Redefined M4 Macros): Document m4_exit,
15543 m4_if, and m4_wrap.
15545 2001-08-03 Akim Demaille <akim@epita.fr>
15547 * lib/m4sugar/m4sugar.m4 (m4_init): Also forbid `_m4_*' tokens.
15548 (m4_divert_pop): Dump the whole diversion stack when a diversion
15549 mismatch happens.
15550 * bin/autom4te.in (&handle_output): Remember of the first
15551 occurrence of a possibly undefined macro, not the last.
15552 Complain about the possibly undefined macros in the same order as
15553 the appear in the output.
15554 * lib/autoconf/Makefile.am (autoconf.m4f): List its dependencies.
15555 * tests/tools.at (autoconf: forbidden tokens, basic)
15556 (autoconf: forbidden tokens, exceptions): No longer sort
15557 autoconf's stderr, as it is now deterministic.
15558 Check that `dnl' is caught.
15560 2001-08-01 Akim Demaille <akim@epita.fr>
15562 * configure.ac: Bump to 2.52c.

15576 * lib/Autom4te/General.pm: Use `carp' and `croak', not `warn' and
15577 `die'.
15578 (&END): New.
15579 * bin/autoconf.in, bin/autom4te.in, bin/autoupdate.in: Remove your
15580 `END', as `Autom4te::General::END' will be triggered.
15581 * bin/autoupdate.in, bin/autoscan.in: Improve error messages accuracy.
15582 * bin/autoupdate.in (File::Compare, File::Copy): Use them instead of

15974 compiler, not the preprocessor.

16017 cross-language link tests can be performed successfully.
16018 (_AC_F77_NAME_MANGLING): Require AC_F77_DUMMY_MAIN. Also put $FLIBS
16019 after $LIBS, for consistency; this should be the general rule since

16021 * doc/autoconf.texi: Document AC_F77_DUMMY_MAIN and AC_F77_MAIN.
16023 2001-06-29 Pavel Roskin <proski@gnu.org>

16026 at-stdout and at-stderr instead of removing the newline
16027 from the echo output, which is not guaranteed to work.
16029 2001-06-28 Jens Petersen <petersen@redhat.com>
16031 * aclang.m4 (_AC_PROG_CXX_EXIT_DECLARATION): Only add declaration to

16093 2001-06-23 Akim Demaille <akim@epita.fr>
16095 * doc/autoconf.texi (Redefined M4 Macros): New.
16097 2001-06-23 Akim Demaille <akim@epita.fr>
16099 * acgeneral.m4 (_AC_INCLUDES_DEFAULT_REQUIREMENTS): Consider

16105 * acgeneral.m4 (_AC_OUTPUT_CONFIG_STATUS): Defer parsing of
