1215 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't look
1216 for a.* when searching for executables, as this prevents users

1233 must not be anonymous.
1234 * lib/autoconf/types.m4 (_AC_CHECK_TYPE_NEW): Remove special case
1235 for C++; this drops support for anonymous struct and union types,
1236 which were problematic anyway.
1237 * tests/semantics.at (AC_CHECK_HEADERS_NEW): Adjust test to work even

1255 with objects too. Document the restrictions on its use.
1256 Document the restrictions on AC_CHECK_ALIGNOF's type argument.
1257 * lib/autoconf/types.m4 (_AC_CHECK_TYPE_NEW):
1258 For C, just try sizeof (TYPE) and sizeof ((TYPE)); if the former
1259 works but the latter doesn't, then it's a valid type.
1260 This lets people use function types and so forth.
1261 For C++ there doesn't seem to be a simple solution, so leave it alone.
1262 (AC_CHECK_SIZEOF): Allow argument to be a variable.
1263 (AC_CHECK_SIZEOF, AC_CHECK_ALIGNOF): Don't bother to invoke
1264 AC_CHECK_TYPE; that wasn't documented or necessary.

1316 * doc/autoconf.texi (Limitations of Usual Tools): Warn about other

1325 2007-03-09 Stepan Kasal <kasal@ucw.cz>
1327 * doc/autoconf.texi (Specifying Names): `--host' does not

1434 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Also
1435 AC_SUBST([MKDIR_P]), so that Automake < 1.10 will pick up its
1436 trace, if a package uses AC_PROG_MKDIR_P explicitly. The actual

1465 <iamacdo@telkomsa.net> and Sam Sexton <Sam.Sexton@reuters.com>.
1467 2007-01-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1469 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Use newlines to
1470 separate items of `ac_user_opts', to avoid long lines.
1471 (_AC_INIT_PARSE_ENABLE2, _AC_ENABLE_IF_ACTION): Adjust.
1473 2007-01-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1475 * doc/autoconf.texi: Fix some typos.
1477 2007-01-05 Paul Eggert <eggert@cs.ucla.edu>
1479 Fix some wording problems noted by Paolo Bonzini in:
1480 http://lists.gnu.org/archive/html/autoconf-patches/2007-01/msg00077.html
1481 * doc/autoconf.texi (Signed Overflow Examples): Give more
1482 discussion about the allow_superuser_privileges example,
1483 and change it a bit to make things clearer.
1484 (Optimization and Wraparound): Clarify whether the compiler
1485 will generate an infinite loop for the example derived from
1486 Autoconf's mktime test.
1487 (Signed Overflow Advice): Say that -ftrapv is meant for debugging.
1488 Also, clarify unsigned multiplication overflow.
1490 2007-01-04 Eric Blake <ebb9@byu.net>
1492 * bin/Makefile.am (RELEASE_YEAR): New macro.
1493 (edit): Use it to supply correct copyright year to scripts.
1494 * bin/autoconf.as (version): Use it.
1495 * bin/autoheader.in ($version): Likewise.
1496 * bin/autom4te.in ($version): Likewise.
1497 * bin/autoreconf.in ($version): Likewise.
1498 * bin/autoscan.in ($version): Likewise.
1499 * bin/autoupdate.in ($version): Likewise.
1500 * bin/ifnames.in ($version): Likewise.
1502 2007-01-02 Paul Eggert <eggert@cs.ucla.edu>
1504 * doc/autoconf.texi (Integer Overflow): Revised based on today's
1505 feedback. The most important changes document what happens when
1506 you convert an out-of-range value to a signed integer type, and
1507 say that (sum < a) != (b < 0) reliably detects overflow when sum =
1508 a + b.
1510 * doc/autoconf.texi (Integer Overflow): Greatly expand and
1511 rewrite, taking notions from the recent discussion on the gcc and
1512 autoconf mailing lists; please see
1513 http://lists.gnu.org/archive/html/autoconf-patches/2006-12/msg00091.html
1514 and follow the many links.
1515 (Integer Overflow Basics, Signed Overflow Examples):
1516 (Optimization and Wraparound, Signed Overflow Advice):
1517 (Signed Integer Division): New sections.
1519 2006-12-28 Steven G. Johnson <stevenj@alum.mit.edu>
1521 * lib/autoconf/general.m4 (AC_DEFINE_TRACE): Don't include
1522 preprocessor macro arguments in traced name.
1523 * doc/autoconf.texi (Defining symbols): Document longstanding
1524 support for AC_DEFINE-ing macros with arguments, and document
1525 behavior when the same variable has multiple AC_DEFINEs.
1526 * lib/autoconf/fortran.m4 (_AC_FC_WRAPPERS): Revert to the
1527 old implementation which AC_DEFINEs the FC_FUNC and FC_FUNC_
1528 macros directly, giving much shorter and simpler code.
1530 2006-12-28 Malcolm Purvis <malcolmp@xemacs.org> (trivial change)
1532 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Insert a
1533 space before "$ac_configure_args" to prevent a 'config.status
1534 --recheck' failure if ac_configure_args doesn't contain a leading
1535 space. This works around a problem with the XEmacs configure.ac,
1536 which uses the (undocumented) ac_configure_args variable
1537 inconsistently with Autoconf.
1539 2006-12-22 Paul Eggert <eggert@cs.ucla.edu>
1541 * lib/autoconf/functions.m4 (AC_FUNC_MKTIME):
1542 Include <limits.h>, and use its INT_MAX to rewrite the
1543 j loop so that it does not overflow 'int'. Problem reported by
1544 Ralf Wildenhues in
1545 <http://lists.gnu.org/archive/html/bug-gnulib/2006-12/msg00084.html>.
1546 Play it safe by shifting left by 1 rather than multiplying by 2,
1547 as GCC is less likely to optimize this away when the value
1548 is signed (when it assumes overflow leads to undefined behavior).
1549 Also, don't assume time_t uses two's complement.
1551 2006-12-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1553 * tests/torture.at (Substitute a 2000-byte string): Avoid using
1554 a 10kB long (multi-line) string literal, OpenServer 5.0.7 ksh
1555 dumps core on it. Report by Tim Rice.
1557 2006-12-18 Steven G. Johnson <stevenj@alum.mit.edu>
1559 * lib/autoconf/general.m4 (AC_ARG_ENABLE): Print help about
1560 --disable-option-checking to --help output even when
1561 AC_PRESERVE_HELP_ORDER is not used.
1562 (_AC_INIT_PARSE_ENABLE2): Print warnings using actual --enable or
1563 --with argument, rather than argument with [-.] replaced by
1564 underscores.
1565 * NEWS: Fix typo in previous change; the news was in the
1566 wrong section.
1568 2006-12-18 Paul Eggert <eggert@cs.ucla.edu>
1570 * NEWS: Warnings are now generated by default for unknown
1571 --enable-* and --with-* options.
1572 * doc/autoconf.texi (Option Checking): Renamed from
1573 (Configure Option Checking). Tighten up the wording a bit.
1574 (External Software, Package Options): Cross-reference to Option
1575 Checking, and use this to shorten our section.
1576 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Prefer test -n
1577 "$x" to test "x$foo" != x.
1578 * lib/autoconf/status.m4 (AC_OUTPUT): Likewise.
1579 Don't warn if $enable_option_checking is "no".
1580 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Initialize
1581 ac_unrecognized_opts to the empty string.
1582 Don't echo the unrecognized opts, as this might mishandle
1583 backslashes or leading -.
1584 (AC_PRESERVE_HELP_ORDER): Put the --disable-option-checking
1585 usage next to the other --disable-FEATURE options in the
1586 help string.
1588 2006-12-18 Steven G. Johnson <stevenj@alum.mit.edu>
1590 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS, _AC_INIT_PARSE_ARGS):
1591 (_AC_INIT_PARSE_ENABLE2, _AC_INIT_HELP, _AC_ENABLE_IF):
1592 Print warning for unrecognized --with and --enable options
1593 (AC_DISABLE_OPTION_CHECKING): New macro to disable warnings.
1594 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS, _AC_OUTPUT_SUBDIRS):
1595 Disable option checking when subdirs are configured.
1596 (AC_OUTPUT): If warnings are enabled, print warning about
1597 unrecognized --with and --enable options at the end of
1598 the configure output (as well as at the beginning).
1599 * doc/autoconf.texi (Option Checking): New node.
1600 Document new option warning functionality.
1602 2006-12-16 Eric Blake <ebb9@byu.net>
1604 * configure.ac (AC_INIT): Bump version, since 2.61a is released.
1605 * NEWS: Start news for current version.
1607 2006-12-15 Paul Eggert <eggert@cs.ucla.edu>
1609 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT):
1610 Define HAVE_GETMNTENT to 1, not to the empty string.
1611 Problem originally reported by Jochen Friedrich in
1612 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=403243>.
1614 This change prompted by a problem report by Andrey Simonenko in
1615 <http://lists.gnu.org/archive/html/bug-autoconf/2006-12/msg00026.html>.
1616 * doc/autoconf.texi (Defining Symbols): AC_DEFINE works for
1617 object-like macros only, in the traditional portable character
1618 set.
1619 * lib/autoconf/general.m4 (AC_DEFINE_TRACE_LITERAL):
1620 Warn about attempts to define things that are not identifiers.
1621 * lib/autoconf/fortran.m4 (_AC_FC_WRAPPERS): Rewrite to avoid
1622 awful hack that AC_DEFINEd macro names containing parentheses.
1624 2006-12-12 Paul Eggert <eggert@cs.ucla.edu>
1626 * doc/autoconf.texi: Undo some of the 2006-12-10 change. It was
1627 too drastic, even if Texinfo in theory requires it for info mode.
1629 (config.status Invocation): Renamed back from Recreating a
1630 Configuration).
1631 (Obsolete config.status Use): Renamed back from Obsolete Recreation.
1632 (Autoconf 2.13): Renamed back from 20th-century Autoconf 2.
1634 2006-12-11 Paul Eggert <eggert@cs.ucla.edu>
1636 * NEWS: Version 2.61a.
1638 2006-12-11 Paul Eggert <eggert@cs.ucla.edu>
1639 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1641 * NEWS: Document changes with echo and printf, and the lack
1642 of limits on the total size of multi-line values of substituted
1643 variables, and the AC_FUNC_FSEEKO fix.
1645 2006-12-10 Paul Eggert <eggert@cs.ucla.edu>
1647 * doc/autoconf.texi (Writing Autoconf Input): Renamed from
1648 Writing configure.ac.
1649 (Autoconf Input Layout): Renamed from configure.ac Layout.
1650 (Recreating a Configuration): Renamed from config.status Invocation.
1651 (Obsolete Recreation): Renamed from Obsolete config.status Use.
1652 (acconfig Header): Renamed from acconfig.h.
1653 (20th-century Autoconf 2): Renamed from Autoconf 2.13.
1654 (Writing Testsuites): Renamed from Writing testsuite.at.
1655 (Autom4te Cache): Renamed from autom4te.cache.
1657 * BUGS: Remove mention of VPATH problem, since it's now documented
1658 not to be a bug in the Autoconf build procedure itself, but rather
1659 a problem with the proprietary `make' programs.
1661 * doc/autoconf.texi (Build Directories): Add a cross reference
1662 to VPATH and Make.
1664 * build-aux/config.guess, build-aux/config.sub, build-aux/texinfo.tex:
1665 * doc/standards.texi: Sync from gnulib.
1667 * man/autoconf.1, man/autoheader.1, man/autom4te.1, man/autoreconf.1:
1668 * man/autoscan.1, man/autoupdate.1, man/config.guess.1:
1669 * man/config.sub.1, man/ifnames.1: Remove from CVS, since they're
1670 generated automatically.
1672 2006-12-06 Paul Eggert <eggert@cs.ucla.edu>
1674 * lib/autoconf/c.m4 (_AC_PROG_CC_C89): Also try -xc99=all, for Sun
1675 C 5.8 on Solaris 10. Using -xc99=all rather than -xc99 bypasses
1676 the buggy -xc99 option of Forte Developer 7 C on Solaris 9.
1678 2006-12-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1680 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Drop the
1681 `CEOF$ac_eof' special marker, the awk script cannot contain a
1682 line matching `^CEOF', so this is not needed any more.
1683 * tests/torture.at (Substitute a newline): Expose the `%!_!# '
1684 special marker in the test.
1686 2006-12-06 Stepan Kasal <kasal@ucw.cz>
1688 * tests/tools.at (autom4te preselections): Use `find -newer';
1689 remove one of the sleeps.
1691 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE): Make it
1692 more readable, using ...
1693 (_AC_INIT_PARSE_ENABLE2): ... this new helper macro.
1695 * doc/autoconf.texi (autoheader Invocation): Do not double-
1696 quote the parameter of `AH_BOTTOM' in the example.
1698 2006-12-05 Stepan Kasal <kasal@ucw.cz>
1700 * doc/autoconf.texi (Configuration Headers): Remove the
1701 example with multiple input files.
1702 (autoheader Invocation): Encourage `AH_BOTTOM', discouraging
1703 multiple input files.
1705 2006-12-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1707 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): When
1708 creating the awk substitution script, handle one input line at a
1709 time, so that the maximum length of a substituted (multi-line)
1710 value is not limited by the size of the sed pattern space.
1711 The trade-off is a slightly repetitive sed script.
1712 * doc/autoconf.texi (Limitations of Usual Tools): Branch labels
1713 can only have up to 7 characters, due to Solaris 10 /bin/sed.
1714 * tests/torture.at (Substitute a 2000-byte string): Increase the
1715 test with several long lines, they should not be caught by sed
1716 limits any more.
1718 * tests/tools.at (autom4te preselections): New test, to flag
1719 entries missing from autom4te.cfg.
1720 Report by David Byron <dbyron@hheld.com>.
1722 * tests/torture.at (Substitute a 2000-byte string): Actually use
1723 AC_PROG_AWK, so the last change works as intended.
1724 (Substitute and define special characters): Likewise.
1725 (Substitute a newline): Likewise.
1727 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Use `$AWK'
1728 instead of `awk' consistently.
1729 (_AC_OUTPUT_CONFIG_STATUS): Initialize $AWK.
1730 * tests/torture.at (Torturing config.status): Test both the
1731 result of AC_PROG_AWK and plain awk.
1732 (Substitute a 2000-byte string): Likewise.
1733 (Substitute and define special characters): Likewise.
1734 (Substitute a newline): Likewise.
1736 2006-12-04 Paul Eggert <eggert@cs.ucla.edu>
1738 * lib/autoconf/functions.m4 (AC_FUNC_FSEEKO): Check that fseeko
1739 can be assigned to a function pointer. Problem reported by
1740 Peter Palfrader in <http://bugs.debian.org/401377>. Based on
1741 part of a patch by Ralf Wildenhues in that same bug report.
1743 2006-12-01 Paul Eggert <eggert@cs.ucla.edu>
1745 * tests/mktests.sh (ac_exclude_list): Exclude AC_FUNC_SETVBUF_REVERSED.
1746 * tests/semantics.at (AC_FUNC_SETVBUF_REVERSED): New test.
1748 2006-12-01 Eric Blake <ebb9@byu.net>
1750 * lib/autoconf/c.m4 (AC_LANG_INT_SAVE): Avoid newline, to aid in
1751 cross-compiling from cygwin to mingw.
1752 Reported by Bob Rossi. This resurrects the 2000-11-30 patch to
1753 aclang.m4, which was mistakenly removed in the 2001-09-17 patch
1754 to lib/autoconf/c.m4.
1756 2006-12-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1758 * lib/m4sugar/m4sh.m4 (_AS_ECHO_PREPARE): Use a longer test
1759 string for more reliable failure. Wrap the entire test that
1760 causes the broken Solaris printf to dump core, in a subshell,
1761 so the segmentation fault message is reliably suppressed.
1762 Fix shell expansion errors by using /usr/ucb/echo always;
1763 avoid an error on systems without it by another subshell.
1764 Avoid m4 expansion of `$1'. Set the zeroth argument of the
1765 subshell-$as_echo to `as_echo', for better error message.
1767 2006-11-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1769 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): If `BASH_ARGV' or
1770 `BASH_SOURCE' contain a newline, set them to empty, as they may
1771 not be unset.
1773 2006-11-27 Paul Eggert <eggert@cs.ucla.edu>
1775 Turn AC_FUNC_SETVBUF_REVERSED into a noop. It's been obsolete for
1776 years and is too hard to maintain now. The last straw was
1777 reported by Jerker Baeck in
1778 <http://lists.gnu.org/archive/html/autoconf/2006-11/msg00102.html>.
1779 * NEWS: AC_FUNC_SETVBUF_REVERSED is now obsolete.
1780 * doc/autoconf.texi (Particular Functions): Move
1781 AC_FUNC_SETVBUF_REVERSED from here...
1782 (Obsolete Macros): ... to here. Say that it does nothing now.
1783 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
1784 Turn into (almost) a no-op.
1786 * lib/autoconf/c.m4 (AC_PROG_GCC_TRADITIONAL, AC_C_CONST):
1787 (AC_C_VOLATILE):
1788 Do not recommend via AN_FUNCTION, AN_IDENTIFIER, or AN_HEADER.
1789 These macros are obsolescent and new applications shouldn't need them.
1790 * lib/autoconf/functions.m4 (AC_FUNC_CLOSEDIR_VOID, AC_REPLACE_FNMATCH):
1791 (AC_FUNC_GETLOADAVG, AC_FUNC_GETPGRP, AC_FUNC_MEMCMP):
1792 (AC_FUNC_SELECT_ARGTYPES, AC_FUNC_SETPGRP, AC_FUNC_STAT, AC_FUNC_LSTAT):
1793 (AC_FUNC_STRFTIME, AC_FUNC_SETVBUF_REVERSED, AC_FUNC_UTIME_NULL):
1794 (AC_FUNC_VPRINTF): Likewise.
1795 * lib/autoconf/headers.m4 (AC_HEADER_DIRENT, AC_HEADER_STAT):
1796 (AC_HEADER_STDC, AC_HEADER_SYS_WAIT, AC_HEADER_TIME): Likewise.
1797 * lib/autoconf/types.m4 (AC_STRUCT_TM): Likewise.
1799 * doc/autoconf.texi (Setting Output Variables): Mention that
1800 @VAR1@VAR2 has unspecified behavior. Problem reported by
1801 Ralf Wildenhues.
1802 * NEWS: Mention this.
1804 * Makefile.am: Put only a single '#' into the copyright notice,
1805 so that it's also present in the output file. Standardize wording
1806 in makefile copyright notices to match GNU coding standards.
1807 * bin/Makefile.am: Likewise.
1808 * doc/Makefile.am: Likewise.
1809 * lib/Makefile.am: Likewise.
1810 * lib/freeze.mk: Likewise.
1811 * lib/autoconf/Makefile.am: Likewise.
1812 * lib/autoscan/Makefile.am: Likewise.
1813 * lib/autotest/Makefile.am: Likewise.
1814 * lib/m4sugar/Makefile.am: Likewise.
1815 * man/Makefile.am: Likewise.
1816 * tests/Makefile.am: Likewise.
1817 * lib/emacs/Makefile.am: Remove copyright notice; it's just a
1818 one-line file.
1820 2006-11-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1822 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Fix error
1823 in the sed script that mangles the awk script: delete up to the
1824 first exclamation mark only.
1825 * tests/torture.at (Substitute and define special characters):
1826 Test '!' too.
1828 2006-11-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1830 Rewrite config files generation: avoid quadratic growth in
1831 the number of substituted variables by using awk instead of sed
1832 for the bulk of the substitutions.
1833 * NEWS: Mention this.
1834 * doc/autoconf.texi (Setting Output Variables): `|#_!!_#|' is also
1835 forbidden in the output (and thus input) file.
1836 * lib/autoconf/status.m4 (_AC_AWK_LITERAL_LIMIT): New macro.
1837 (_AC_OUTPUT_FILES_PREPARE): Instead of several sed scripts,
1838 generate just one large awk script for substitutions,
1839 eliminating much of the earlier complexity, while adding some
1840 new complexity. Only expand the substitution templates at
1841 configure time, for smaller configure script size. If
1842 _AC_SUBST_FILES are used, test 'awk' for working getline support
1843 at config.status time. If absent, interpolate through the
1844 shell. The awk script was written with much help
1845 from Paolo Bonzini and Paul Eggert.
1846 (_AC_SED_CMD_NUM, _AC_SED_DELIM_NUM, _AC_SED_FRAG): Removed.
1847 (_AC_SED_FRAG_NUM): Likewise.
1848 (_AC_SUBST_CMDS): Renamed from...
1849 (_AC_SED_CMDS): ...this.
1850 (_AC_OUTPUT_FILE): Use _AC_SUBST_CMDS.
1851 * tests/torture.at (Substitute a 2000-byte string): Also
1852 substitute a line with 1000 words, and a variable with several
1853 long lines.
1854 (Substitute and define special characters): Test awk special
1855 characters, and put substitution input strings `@foo@' in the
1856 output, to test that no recursion happens; test several other
1857 combinations from Paolo Bonzini.
1859 2006-11-25 Paul Eggert <eggert@cs.ucla.edu>
1861 * lib/autotest/general.m4 (AT_INIT): Undo recent changes
1862 that replaced echo with AS_ECHO where this wasn't necessary.
1863 Problem reportd by Ralf Wildenhues.
1864 * lib/m4sugar/m4sh.m4 (_AS_ECHO_PREPARE): Port to Solaris 7,
1865 where "/usr/bin/printf '%s\n' S" dumps core if S is long.
1866 This is Sun bug 4206210. Problem reportd by Ralf Wildenhues.
1868 2006-11-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1870 * lib/freeze.mk (GREP): Removed, no need to initialize this.
1872 2006-11-21 Paul Eggert <eggert@cs.ucla.edu>
1874 * doc/autoconf.texi (Limitations of Usual Tools): Don't claim
1875 that traditional Awk lacks 3-arg "split". It has it.
1876 Mention that FS must be a single character, and a few other
1877 99-byte limits of traditional Awk.
1878 Mention that if (i in a) doesn't work with traditional Awk.
1880 2006-11-18 Paul Eggert <eggert@cs.ucla.edu>
1882 * tests/autotest.at (BSx641-newline in command):
1883 (BS-BS-newline in command, BSx640-newline in command):
1884 (Newline-CODE-BS-newline in command):
1885 (Single-quote-BS-newline in command):
1886 (Single-quote-newline-BS-newline in command):
1887 Use printf '%s\n' instead of echo, for portability to hosts
1888 where echo interprets backslashes. This will break on hosts
1889 that lack printf, but for now let's assume all such hosts
1890 are dead (if not, we should get reports of test failures).
1892 2006-11-17 Paul Eggert <eggert@cs.ucla.edu>
1894 'echo' has some portability problems, when given a first argument
1895 with a leading '-', or when given any argument containing '\'.
1896 Avoid using 'echo' in these cases.
1897 * bin/Makefile.am $(bin_SCRIPTS): Rewrite to avoid 'echo' entirely.
1898 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX, AC_PROG_OBJC): Likewise.
1899 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
1900 * lib/autotest/general.m4 (AT_INIT): Likewise.
1901 * bin/autoconf.as: Use AS_ECHO rather than plain echo, when the
1902 argument might be unportable.
1903 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Likewise.

1921 (AS_TR_SH, AS_TR_CPP, AS_VAR_GET): Likewise.
1922 * bin/autoconf.as: Redo verbose flag implementation, as the old
1923 scheme wouldn't work with AS_ECHO.
1924 * lib/autotest/general.m4 (AT_INIT): Likewise.
1925 * lib/autoconf/general.m4 (AC_MSG_RESULT, AC_MSG_RESULT_UNQUOTED):

1965 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE): Fix some typos

2084 ./micro-suite -l and the title in micro-suite.log.
2085 (Backquote in a test title,
2086 Single-quote in a test title,
2087 Double-quote in a test title): Don't expect failure anymore.
2088 (Backslash in a test title): Put a non-whitespace character after the
2089 backslash so that Bourne shells might actually see it as an escape
2090 sequence.
2091 (Brackets in a test title,
2092 Pound in a test title,
2093 Comma in a test title,
2094 Quoted Macro in a test title,

2101 AT_SETUP call so that no M4 code is commented inadvertently somewhere.
2102 The visible effect was a stray [] in the testsuite output.
2104 2006-10-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2106 * doc/autoconf.texi (Limitations of Builtins): Do not invoke
2107 `trap ... 0' inside a function, for AIX sh.
2109 2006-10-26 Paul Eggert <eggert@cs.ucla.edu>
2111 * tests/base.at (AC_COMPUTE_INT): Test **0** rather than 1 / 0,
2112 since powerpc-apple-darwin8-gcc-4.0.1 (Apple Computer, Inc. build
2113 5363) simply issues a warning when dividing by zero at compile
2114 time. Problem reported by Elias Pipping.
2116 2006-10-26 Eric Blake <ebb9@byu.net>
2118 * THANKS: Update.
2119 * doc/autoconf.texi (Evaluation Macros): Improve the example to
2120 show effect on macros that expand with commas.
2121 Reported by Joel E. Denny.
2123 * tests/m4sugar.at (m4_warn, m4_require: circular dependencies):

2148 If FUNCTION-BODY is nonempty, use AC_LINK_IFELSE rather than
2149 AC_COMPILE_IFELSE, to work around problem with OSF/1 4.0F fseeko
2150 reported by Nelson H. F. Beebe for Coreutils 6.4.
2152 * tests/tools.at (autoconf --trace: user macros): Remove test
2153 for tracing multiline macros, since m4 1.4.7a uses a different
2154 way to number lines. Problem reported by Ralf Wildenhues.
2156 2006-10-24 Stepan Kasal <kasal@ucw.cz>
2158 * bin/autom4te.in (handle_m4): Do not redirect stdin to
2159 /dev/null since the heuristics for interactive behaviour was
2160 fixed in CVS m4.
2162 * bin/autom4te.in: With --force, always refresh the output
2163 file. Problem reported by Greg Schafer <gschafer@zip.com.au>.

2167 2006-10-23 Paul Eggert <eggert@cs.ucla.edu>

2184 * lib/autoconf/types.m4: All uses of AC_CACHE_CHECK_INT changed.
2185 * tests/base.at (AC_COMPUTE_INT): Test this, not AC_CACHE_CHECK_INT.
2187 2006-10-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2189 * doc/autoconf.texi (Limitations of Usual Tools): Fix two typos.
2191 2006-10-19 Eric Blake <ebb9@byu.net>
2193 * lib/m4sugar/m4sugar.m4 (m4_mkstemp): New macro.

2213 2006-10-14 Stepan Kasal <kasal@ucw.cz>
2215 * lib/m4sugar/m4sh.m4 (AS_LITERAL_IF): Expand $1 before
2216 looking for special shell characters.
2217 * lib/autoconf/functions.m4 (AC_CHECK_FUNC): Do not expand the
2218 macro defined by AS_VAR_PUSHDEF before passing it as a
2219 parameter.
2220 * lib/autoconf/general.m4 (AC_CHECK_FILE, AC_CHECK_DECL):
2221 * lib/autoconf/libs.m4 (AC_SEARCH_LIBS, AC_CHECK_LIB):

2230 2006-10-14 Paul Eggert <eggert@cs.ucla.edu>
2232 (Imported from Automake.)
2233 * build-aux/install-sh (posix_mkdir): Reject FreeBSD 6.1 mkdir -p -m,
2234 which incorrectly sets the mode of an existing destination
2235 directory. In some cases the unpatched install-sh could do the
2236 equivalent of "chmod 777 /" or "chmod 0 /" on a buggy FreeBSD
2237 system. We hope this is rare in practice, but it's clearly worth
2238 fixing. Problem reported by Alex Unleashed in
2239 <http://lists.gnu.org/archive/html/bug-autoconf/2006-10/msg00012.html>.
2240 Also, don't bother to check for -m bugs unless we're using -m;
2241 suggested by Stepan Kasal.
2243 2006-10-14 Paul Eggert <eggert@cs.ucla.edu>

2250 Report from Bruno Haible.
2252 2006-03-10 Alexandre Duret-Lutz <adl@gnu.org>
2253 * lib/Autom4te/ChannelDefs.pm: Make -Wportability the default in
2254 gnu and gnits modes.
2256 Import this change from Config:
2258 2006-09-20 Ben Elliston <bje@gnu.org>

2261 Import this change from Gnulib:
2263 2006-09-16 Karl Berry <karl@gnu.org>

2270 * build-aux/texinfo.tex (\singlequotechar): rename to \codequoteright.
2271 (\quoteexpand): rename to \rquoteexpand.
2272 (\codequoteleft): new def, to look for @set codequotebacktick.
2273 (\lquoteexpand, \quoteexpand): new defs.
2274 (\lquoteChar, \rquoteChar, \dashChar, \underChar: new \chardef's.
2275 (\code): must use new \...Char values, since now ` is active.
2277 2006-08-26 Karl Berry <karl@gnu.org>
2278 * build-aux/texinfo.tex (\textdegree): New command.
2280 2006-08-12 Karl Berry <karl@gnu.org>
2281 * build-aux/texinfo.tex (error \box0): smaller font.
2283 2006-10-14 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2285 * doc/autoconf.texi (Autoheader Macros): Fix syntax error.
2287 2006-10-13 Stepan Kasal <kasal@ucw.cz>
2289 * doc/autoconf.texi (Autoheader Macros): Warn that the text
2290 added to the template can get mangled.
2292 2006-10-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2294 * lib/autoconf/functions.m4 (AC_FUNC_OBSTACK): In the test,
2295 include the default headers, and redefine obstack_chunk_alloc
2296 and obstack_chunk_free. Fixes false failure with glibc.
2298 2006-10-12 Paul Eggert <eggert@cs.ucla.edu>
2300 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Set as_executable_p,
2301 for backward compatibility with Libtool 1.5.22. Problem reported
2302 by Ralf Wildenhues.
2304 2006-10-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2306 * lib/autoconf/c.m4 (AC_PROG_GCC_TRADITIONAL): Require
2307 AC_PROG_CC.
2308 Report by IOhannes m zmoelnig <zmoelnig@iem.at>.
2310 2006-10-11 Paul Eggert <eggert@cs.ucla.edu>
2312 * NEWS: AC_USE_SYSTEM_EXTENSIONS now defines _TANDEM_SOURCE for
2313 the NonStop platform.
2314 * doc/autoconf.texi (Posix Variants): Likewise.
2315 * lib/autoconf/specific.m4 (AC_USE_SYSTEM_EXTENSIONS): Likewise.
2317 * lib/m4sugar/m4sh.m4 (AS_TEST_X): New macro.
2318 (AS_EXECUTABLE_P): Use as_test_x rather than as_executable_p.
2319 (_AS_TEST_PREPARE): Set as_test_x rather than as_executable_p.
2320 Use a better substitute, by inspecting the output of "ls"
2321 rather than just using ":".
2322 * lib/autoconf/general.m4 (_AC_LINK_IFELSE): Use AS_TEST_X
2323 rather than AS_EXECUTABLE_P, since we needn't worry about
2324 non-regular files here.
2326 * NEWS: Autoconf-generated shell scripts no longer export BIN_SH,
2327 due to configuration hassles with this. See Tonya Underwood's report
2328 <http://lists.gnu.org/archive/html/bug-autoconf/2006-10/msg00003.html>.
2329 * doc/autoconf.texi (Special Shell Variables): Likewise.

2337 2006-10-11 Stepan Kasal <kasal@ucw.cz>
2339 * lib/m4sugar/m4sh.m4 (AS_BOURNE_COMPATIBLE): Move the
2340 initialization which is not inherited through the environment
2341 (_AS_BOURNE_COMPATIBLE): ... to this new macro.
2342 (_AS_RUN): Call _AS_BOURNE_COMPATIBLE, not AS_BOURNE_COMPATIBLE.
2344 2006-10-09 Paul Eggert <eggert@cs.ucla.edu>

2347 problems with mkdir -p -m.
2349 2006-10-06 Paul Eggert <eggert@cs.ucla.edu>
2351 * lib/autoconf/c.m4 (_AC_PROG_PREPROC_WORKS_IFELSE): Remove
2352 comment about ac_cpp_err; it was incorrect, and anyway
2353 ac_cpp_err is being removed below.
2354 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE): Don't
2355 set ac_cpp_err to 'yesyes' if preproc_warn_flag and werror_flag
2356 are both 'yes'. In fact, don't bother setting ac_cpp_err at all;
2357 nobody uses it.
2358 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't log our funky tests
2359 with werror_flag and conftest.err and so forth. This is more
2360 compatible with how _AC_PROG_PREPROC_WORKS_IFELSE behaves,
2361 and anyway the user shouldn't normally want to see this gorp logged.
2362 Problem reported by Ralf Wildenhues.
2363 * lib/autoconf/lang.m4 (AC_LANG_WERROR): werror_flag's default is
2364 empty, not 'no', since the rest of the code uses 'test -z'.
2366 2006-10-04 Paul Eggert <eggert@cs.ucla.edu>
2368 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE):
2369 Use a single call to AC_DO_TOKENS rather than multiple, for
2370 efficiency.

2372 Problem reported by mwoehlke in
2373 <http://lists.gnu.org/archive/html/bug-coreutils/2006-10/msg00048.html>.
2375 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Use "test -x /" rather
2376 than creating a file to use with test -x; this is much faster.
2378 2006-10-02 Bruno Haible <bruno@clisp.org>
2380 * lib/autom4te.in (Automake-preselections): Add
2381 AM_GNU_GETTEXT_INTL_SUBDIR, for automake 1.10.
2383 2006-09-27 Stepan Kasal <kasal@ucw.cz>
2385 * doc/autoconf.texi (Writing testsuite.at): Fix a typo: for
2386 standard error, `experr' should be used, not `expout'.
2388 2006-09-26 Paul Eggert <eggert@cs.ucla.edu>
2390 * lib/autoconf/functions.m4 (AC_FUNC_FSEEKO): Don't compile the
2391 fseeko testing program twice; just use the earlier result.
2392 * lib/autoconf/specific.m4 (_AC_SYS_LARGEFILE_MACRO_VALUE):
2393 Set cache var to 'unknown' (not 'no') if leaving the macro unset
2394 still doesn't let the program compile.

2396 failed.
2398 * lib/autoconf/functions.m4: Fix problems reported by Ralf Wildenhues.

2402 expressions.

2411 for a declaration of wait3.
2413 2006-09-26 Paul Eggert <eggert@cs.ucla.edu>

2416 * doc/autoconf.texi (Generic Declarations): Clarify that AC_CHECK_DECL
2417 can apply to constants too, and that it checks for macro defns.
2418 * lib/autoconf/general.m4 (AC_CHECK_DECL): Assume C89 or better,
2419 and simply cast the identifier to void. This handles structure
2420 values. Problem reported by Ralf Wildenhues.

2493 * lib/autoconf/general.m4 (AC_CONFIG_MACRO_DIR): Remove a
2494 mistaken comment: the path has to be relative; do not use
2495 the path at runtime.
2497 2006-09-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2499 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Quote the

2509 * doc/autoconf.texi (Input): Clarify role of AC_CONFIG_MACRO_DIR.
2510 * lib/autoconf/general.m4 (AC_CONFIG_MACRO_DIR): Do not check
2511 for the existence of the directory at configure-time. That's
2512 too late, anyway. Problem reported by Stefan Seefeld.
2514 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Avoid bug in UnixWare
2515 7.1.4 /usr/bin/posix/sh described by Tim Rice in
2516 <http://lists.gnu.org/archive/html/bug-autoconf/2006-09/msg00017.html>.
2518 2006-09-11 Stepan Kasal <kasal@ucw.cz>
2520 * tests/local.at (AT_CHECK_M4): Fix this so that the testsuite
2521 works with GNU M4 1.4.3 again; make the normalized form
2522 match the current m4 message; fix the description.
2523 * test/tools.at (autom4te cache): Adapt to the change.
2525 2006-09-08 Paul Eggert <eggert@cs.ucla.edu>
2527 * lib/autoconf/functions.m4 (AC_FUNC_MKTIME): Add year_2050_test
2528 to catch glibc bug 2821
2529 <http://sourceware.org/bugzilla/show_bug.cgi?id=2821>.
2531 Merge from gnulib as follows: Use AC_CHECK_HEADERS_ONCE instead of
2532 AC_CHECK_HEADERS, and likewise for AC_CHECK_FUNCS_ONCE and
2533 AC_CHECK_FUNCS. Don't check for stdlib.h, since we now
2534 assume C89.

2556 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Prefer xlf90/xlf95 over
2557 f90/f95 because the latter drivers of AIX Fortran 9.1 do not
2558 accept files with extension `.f'. For consistency, also prefer
2559 xlf over f77.
2560 * doc/autoconf.texi (Fortran Compiler): Remove mention of bug
2561 from last patch.

2582 except the first two arguments are reversed.
2583 * doc/autoconf.texi (Caching Results): New macro AC_CACHE_CHECK_INT.
2584 (Generic Compiler Characteristics): AC_COMPUTE_INT no longer
2585 caches nor outputs a diagnostic. Suggested by Bruno Haible.

2631 * lib/autoconf/programs.m4 (AC_PROG_LEX): Let _AC_PROG_LEX_YYTEXT_DECL
2632 deal with LEXLIB.
2633 (_AC_PROG_LEX_YYTEXT_DECL): Handle caching correctly; the old code
2634 didn't work if some values were cached but not others. Test for
2635 broken lex libraries like native ia64-hp-hpux11.22; see
2636 <http://sources.redhat.com/ml/binutils/2003-12/msg00337.html>, and
2637 work around the problem by preferring an empty LEXLIB to -lfl or
2638 -ll. Let the user set LEXLIB='' to indicate no library needed.
2640 * NEWS: Recommend M4 1.4.6 instead of 1.4.5.
2641 * README: Likewise.

2791 with '-e a...'. Problems reported by Ralf Wildenhues.
2793 2006-08-12 Alexandre Julliard <julliard@winehq.org> (tiny change)
2795 * lib/autoconf/libs.m4 (AC_PATH_X_DIRECT): Replace another
2796 check for libXt by a check for libX11.
2798 2006-08-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2800 * doc/autoconf.texi (config.status Invocation): Adjust according
2801 to last change.
2803 2006-08-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2805 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): `config.status
2806 --help' should mention that `--version' outputs configuration
2807 settings. Report by Bruno Haible.
2809 2006-08-06 Paul Eggert <eggert@cs.ucla.edu>
2811 Fix test suite failures reported by Pierre in
2812 <http://lists.gnu.org/archive/html/bug-autoconf/2006-08/msg00005.html>.
2813 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't claim
2814 the compiler created a file "b.out" when it didn't create anything
2815 at all.
2816 * lib/autoconf/specific.m4 (AC_SYS_INTERPRETER):
2817 Discard stderr too, when invoking the test script.
2819 2006-08-05 Alexandre Julliard <julliard@winehq.org> (tiny change)
2821 * lib/autoconf/libs.m4 (AC_PATH_XTRA): Fixed a typo
2822 in the restoring of the werror flag.
2824 2006-07-24 Paul Eggert <eggert@cs.ucla.edu>
2826 * doc/autoconf.texi (Volatile Objects): Be even a little
2827 less skeptical about "volatile", after discussion with
2828 Bruno Haible on bug-gnulib.
2829 (Limitations of Usual Tools): Warn about sed stripping
2830 leading white space from text. From Bruno Haible.
2832 2006-07-20 Paul Eggert <eggert@cs.ucla.edu>
2834 * lib/autoconf/libs.m4 (AC_PATH_XTRA): Don't use -R if the
2835 compiler complains about it, even if things works after the
2836 complaint. Problem reported by Peter O'Gorman.
2838 * doc/autoconf.texi (Preset Output Variables): Document CFLAGS,
2839 CPPFLAGS, and LDFLAGS better. Problem reported by Bruno Haible.
2840 Similarly for CXXFLAGS, OBJCFLAGS, ERLCFLAGS.
2842 2006-07-17 Paul Eggert <eggert@cs.ucla.edu>
2844 * lib/autoconf/libs.m4 (AC_PATH_XTRA): Do the check for space
2845 after -R regardless of host. Patrick Welche reports that this
2846 fixes things on NetBSD 3.99.
2848 * NEWS: Recommend M4 1.4.5.
2849 * README: Likewise.
2850 * doc/autoconf.texi (Introduction, Why GNU M4): Likewise.
2851 * tests/tools.at (autom4te cache): Update wording of diagnostic
2852 to match M4 1.4.5.
2854 2006-07-07 Paul Eggert <eggert@cs.ucla.edu>
2856 * doc/autoconf.texi (C Compiler): Add a ref to Volatile Objects
2857 under AC_C_VOLATILE.
2858 (Volatile Objects): Be a little less skeptical about what
2859 "volatile" means. Derived from thoughts by Ben Pfaff in
2860 <http://lists.gnu.org/archive/html/bug-gnulib/2006-07/msg00092.html>.
2862 2006-07-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2864 * doc/autoconf.texi: Fix some typos.
2866 2006-07-07 Paul Eggert <eggert@cs.ucla.edu>
2868 * tests/torture.at (Configuring subdirectories): Set CONFIG_SITE
2869 more globally, since the 2006-06-30 patch didn't suffice. Problem
2870 reported by Keith Marshall. Also, don't bother with builddir2,
2871 since it shouldn't be needed any more.
2873 2006-07-07 Paolo Bonzini <bonzini@gnu.org>
2875 * doc/autoconf.texi (Generic compiler characteristics):
2876 Document AC_COMPUTE_INT. Fix wrong statements on Default
2877 Includes for AC_CHECK_SIZEOF and AC_CHECK_ALIGNOF.
2879 * lib/autoconf/general.m4 (AC_COMPUTE_INT): New.
2880 (_AC_COMPUTE_INT): Add obsoletion warnings.
2881 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF, AC_CHECK_ALIGNOF): Use
2882 AC_COMPUTE_INT.
2884 * NEWS: Document change.
2886 2006-07-05 Paul Eggert <eggert@cs.ucla.edu>
2888 * doc/autoconf.texi (Volatile Objects): New section.
2890 * NEWS: Document previous change.
2892 2006-07-02 Paul Eggert <eggert@cs.ucla.edu>
2894 * lib/autoconf/types.m4 (AC_TYPE_LONG_LONG_INT):
2895 Require that long long int be at least 64 bits wide. C99 requires
2896 this and enough programs depend on it so we should check for it.
2897 Bruno Haible reports in
2898 <http://lists.gnu.org/archive/html/bug-gnulib/2006-06/msg00286.html>
2899 that long long int is 32 bits wide with some nonstandard compilers.
2900 (AC_TYPE_UNSIGNED_LONG_LONG_INT): Likewise.
2902 2006-06-30 Paul Eggert <eggert@cs.ucla.edu>
2904 * tests/torture.at (Configuring subdirectories): Set CONFIG_SITE
2905 to a nonexistent file, so that we don't have to worry about
2906 a local site configuration that doesn't use /usr/local.
2907 Problem reported by Keith Marshall in
2908 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00133.html>.
2910 2006-06-28 Paul Eggert <eggert@cs.ucla.edu>
2912 * doc/autoconf.texi: Be more consistent about using @acronym with
2913 "HP" and "HP-UX". Remove mention of OSF; the old version wasn't
2914 quite right (it talked about "OSF/Tru64", even though the
2915 operating systems were called OSF/1, Digital UNIX, and Tru64 UNIX,
2916 and it even mentioned "OSF 4"!) and at this point there's little
2917 reason to talk about OSF any more, since it died in 1994.
2918 (Specific Compiler Characteristics): Simplify example of
2919 negative-size array.
2920 (File Descriptors): Reorder to make the text flow better.
2921 Remove joke about "appreciate the various levels"; I didn't get it.
2922 Add remark about HP-UX sh -x bug with stderr noted by Bob Proulx in
2923 <http://lists.gnu.org/archive/html/bug-coreutils/2006-06/msg00225.html>.
2924 (File Descriptors, Limitations of Usual Tools):
2925 Tone down the advice against renaming or removing open files.
2926 (Limitations of Usual Tools): Add a new section, on 'rm'.
2928 2006-06-26 Stepan Kasal <kasal@ucw.cz>
2930 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Use -lX11, not
2931 -lXt in LIBS, idea from Karsten Hopp; this was due since
2932 this change:
2934 2005-09-18 Paul Eggert <eggert@cs.ucla.edu>
2935 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Look for X11/Xlib.h
2936 and XrmInitialize rather than X11/Intrinsic.h and XtMalloc
2937 (which belong to Xt, not X itself). See Debian bug 327655.
2939 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2941 * configure.ac (AC_INIT): Bump to 2.60a.
2942 * NEWS: Update.
2944 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2946 Version 2.60.
2948 * configure.ac, NEWS: Update.
2950 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2952 * config/texinfo.tex: Sync from upstream.
2954 * bin/autom4te.in (handle_traces): Transform the `@S|@'
2955 quadrigraph correctly in traces.
2957 * NEWS, lib/Autom4te/C4che.pm, lib/autoconf/functions.m4:
2958 Fix typos.
2960 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Expand tests for
2961 datarootdir-related errors only if AC_DATAROOTDIR_CHECKED is
2962 not defined.
2963 * doc/autoconf.texi (Changed Directory Variables): New node,
2964 to document the whole `datarootdir' business a bit better.
2965 * NEWS: Update.
2966 * tests/torture.at (datarootdir workaround): Extend test.
2967 Prompted by report by Alexandre Julliard.
2969 2006-06-22 Paul Eggert <eggert@cs.ucla.edu>
2971 * lib/autoconf/c.m4 (_AC_PROG_CC_C89): Check for C89 incompatibility
2972 when using default mode of IBM C 6 for AIX. Problem and two-line
2973 fix reported by Larry Jones.
2975 2006-06-22 Alexandre Julliard <julliard@winehq.org>
2977 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Avoid warning
2978 about literal '${datarootdir}' if a definition is found in the
2979 output file.
2981 2006-06-20 Paul Eggert <eggert@cs.ucla.edu>
2983 * NEWS: Use "M4" rather than "m4" when appropriate.
2984 Problem reported by Eric Blake.
2985 * doc/autoconf.texi: Likewise.
2986 Use @acronym around BSD, GCC, and GNU when appropriate.
2987 (Why GNU M4): Renamed from "Why GNU m4".
2988 (Redefined M4 Macros): Mention that Posix
2989 m4wrap takes only 1 argument, but GNU M4 1.4.x takes more.
2990 (Buffer Overruns): Mention size_t and ptrdiff_t as alternatives
2991 to int.
2993 2006-06-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2995 * bin/autom4te.in (handle_output): Do not forbid the empty
2996 pattern.
2997 * tests/tools.at (autoconf: the empty token): New test.
2999 2006-06-20 Stepan Kasal <kasal@ucw.cz>
3001 * lib/m4sugar/m4sugar.m4 (m4_init): Merge the two m4_wrap
3002 calls, so that we do not care whether they are LIFO or FIFO;
3003 in the m4_wrap, do not check which diversion is the topmost
3004 one, just check that the stack is balanced at the end.
3005 * lib/m4sugar/m4sh.m4 (AS_INIT): We are going to change the
3006 base diversion forever--pop the previous diversion before
3007 opening the new one; consequently, remove the m4_wrap call.
3008 * lib/autotest/general.m4 (AT_INIT): Likewise.
3009 * tests/m4sugar.at: Do not use
3010 m4_wrap([m4_diversion_pop([..])]), for educational purposes.
3012 2006-06-19 Paul Eggert <eggert@cs.ucla.edu>
3013 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3015 * NEWS: Document that m4wrap/m4_wrap might not be LIFO.
3016 * doc/autoconf.texi (Redefined M4 Macros): Likewise.
3017 Rework example of m4wrap token-pasting trouble so that it doesn't
3018 care whether it's LIFO or FIFO.
3019 Fix some "contrary to"s that are awkward in English.
3021 2006-06-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3023 * lib/autoconf/types.m4 (_AC_TYPE_INT): Set `$ac_cv_c_int$1_t'
3024 to `yes' instead of `int$1_t' if the type is found, for more
3025 consistent configure output (where $1 is the number of bits).
3026 (_AC_TYPE_UINT): Likewise for `uint$1_t'.
3027 Suggested by Bruno Haible.
3029 * lib/autoconf/types.m4 (_AC_TYPE_UNSIGNED_INT): Solaris 2.5.1
3030 needs _UINT8_T and _UINT64_T defines as well, to avoid clashes
3031 with system headers. Report by Bruno Haible.
3033 2006-06-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3035 * config/config.guess, config/config.sub: Sync from upstream.
3037 * bin/Makefile.am (autoconf.in): Use `--melt' for autom4te,
3038 in order to avoid picking up an older installed frozen m4sh.m4f.
3039 Besides an outdated shell startup, this could have been created
3040 by an earlier M4 version with incompatible frozen file format.
3042 2006-06-16 Paul Eggert <eggert@cs.ucla.edu>
3044 * README: Recommend m4 1.4.4 instead of 1.4.3..
3045 * doc/autoconf.texi: Likewise.
3046 (Special Chars in Names): Say that $(.FOO) is portable, as
3047 suggested by Stepan Kasal.
3048 (Installation Directory Variables, Build Directories):
3049 (Automatic Remaking, Subdirectories, Fortran Compiler):
3050 (Making testsuite Scripts, Defining Directories):
3051 Quote variable usages better.
3052 (Making testsuite Scripts): Add clean-local rule to makefile
3053 snippet, by Eric Blake.
3054 (Installation Directory Variables): Fix table item font.
3055 Reword slightly to clarify. Generalize advice about
3056 not using special characters to include all file-related
3057 vars, not just VPATH.
3058 (Special Chars in Variables): Warn about special characters in
3059 $(srcdir) too.
3060 (Assignments): Clarify default-value example as suggested by
3061 Ralf Wildenhues in
3062 <http://lists.gnu.org/archive/html/autoconf-patches/2006-06/msg00072.html>.
3063 (Special Shell Variables): Note leading ./ or ../, as suggested
3064 by Eric Blake.
3065 (Limitations of Builtins): Under cd, warn about CDPATH.
3066 (The Make Macro MAKEFLAGS): Untabify. Problem reported by
3067 Ralf Wildenhues.
3069 2006-06-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3071 * doc/autoconf.texi (Configuration Actions): Remove duplicate
3072 `@var', for texi2html.
3073 (Systemology): Some more word wrapping, for DVI output.
3074 (autom4te Invocation): The short option for `--melt' is `-M',
3075 not `-m'.
3077 2006-06-15 Paul Eggert <eggert@cs.ucla.edu>
3079 * doc/autoconf.texi: More formatting and English tweaks,
3080 many suggested by Ralf Wildenhues.
3081 Reword to avoid "@code{...}'s" and the like, since it's ugly
3082 with Emacs info mode. discontents -> woes.
3083 Put a few "will"s back. time stamp -> timestamp.
3084 side-effect -> side effect.
3086 2006-06-14 Paul Eggert <eggert@cs.ucla.edu>
3088 * doc/autoconf.texi (Initializing configure, Shell Substitutions):
3089 Warn about $@ not persisting. Problem reported by Julien Danjou in
3090 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=372179>.
3091 (Special Chars in Names): Renamed from Leading _ in Macro Names.
3092 Mention other special chars, too.
3094 2006-06-14 Eric Blake <ebb9@byu.net>
3096 * doc/autoconf.texi (The Make Macro MAKEFLAGS): New node.
3098 2006-06-13 Paul Eggert <eggert@cs.ucla.edu>
3100 * doc/autoconf.texi: Some systematic minor improvements, as
3101 follows. Use "makefile" when talking about makefiles
3102 generally (which might be named "makefile" or "Makefile" or even
3103 "foo.mk"), "Makefile" when talking about a specific makefile
3104 called "Makefile". This unclutters the text from weird quotes
3105 (e.g., "`Makefile's" in info mode). Similarly, use "@var{foo}
3106 values" rather than "@var{foo}s" and similar constructs containing
3107 "}s". Use "Make rules" rather than "Makefile rules". Minor
3108 English-language improvements. Change the prefix "sub-" to "sub"
3109 and "re-" to "re".
3110 Put blank lines around examples more consistently.
3111 Avoid "rather" and "very" as intensifiers.
3112 Avoid "will" as an auxiliary.
3113 (Limitations of Make): Split this node into....
3114 (Portable Make, $< in Ordinary Make Rules, Failure in Make Rules):
3115 (Leading _ in Macro Names, Backslash-Newline-Newline):
3116 (Backslash-Newline Comments, Long Lines in Makefiles):
3117 (Macros and Submakes, The Make Macro SHELL, Comments in Make Rules):
3118 (obj/ and Make, make -k Status, VPATH and Make):
3119 (VPATH and Double-colon, $< in Explicit Rules):
3120 (Automatic Rule Rewriting, OSF/Tru64 Directory Magic):
3121 (Make Target Lookup, Single Suffix Rules, Timestamps and Make):
3122 New nodes, resulting from splitup of Limitations of Make.
3123 All cross-references changed. Raise the top node from
3124 a section to a chapter, and all subnodes accordingly.
3125 Redo the introductory wording to match the new organization.
3126 (Installation Directory Variables): Use an example that is
3127 closer to what Autoconf actually does. Mention that VPATH's
3128 value should not contain metacharacters or white space.
3129 (Fortran Compiler): Fix a VPATH bug in an example.
3130 (Leading _ in Macro Names): Mention that this problem is no longer
3131 of practical concern.
3132 (VPATH and Make): Reword the advice to make it clearer
3133 that Autoconf and Automake support VPATH in non-GNU make, but
3134 many packages have bugs in this area.
3135 ($< in Explicit Rules): Refer to Build Directories rather
3136 than using a (non-VPATH-safe) example.
3137 (Automatic Rule Rewriting): Mention the sort of disaster that
3138 can ensue with Solaris-style rule rewriting with VPATH.
3140 2006-06-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3142 * doc/install.texi (Compilers and Options): Weaken the
3143 suggestion to use GNU make for VPATH builds.
3145 * lib/autom4te.in (Automake-preselections): Add AM_PROG_CXX_C_O,
3146 AM_PROG_F77_C_O, AM_PROG_FC_C_O, AC_FC_SRCEXT, AC_FC_FREEFORM.
3148 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Fix M4 quotation
3149 in regular expression.
3151 2006-06-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3153 * doc/autoconf.texi (Installation Directory Variables):
3154 Drop extra @samp from `@table @samp' item.
3155 (Limitations of Usual Tools): Comment fix.
3156 Do not nest @samp just to point to other table items.
3157 (Writing testsuite.at) <AT_CHECK>: The second argument to
3158 `@dvar' is already @samp'ed.
3159 (Making testsuite Scripts) <AC_CONFIG_TESTDIR>: Likewise,
3160 do not use @var in the second argument.
3162 2006-06-07 Paul Eggert <eggert@cs.ucla.edu>
3164 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Look for
3165 $as_shell.exe too. Problem reported by Andreas Buening in
3166 <http://lists.gnu.org/archive/html/autoconf/2006-06/msg00038.html>.
3168 2006-06-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3170 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA): Work around
3171 `unused variable' compiler warning, for `-Wall -Werror'.
3172 Reported by Jaap Haitsma in
3173 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00012.html>.
3175 2006-06-06 Paul Eggert <eggert@cs.ucla.edu>
3177 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Remove core file, in
3178 case the compiler dumps core. Problem reported for
3179 OpenServer 5.0.7 by Tim Rice in
3180 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00019.html>.
3181 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE):
3182 Likewise.
3184 2006-06-06 Tim Rice <tim@multitalents.net>.
3186 * lib/freeze.mk: Quiet check-forbidden-patterns so the string
3187 "ERROR" only shows up in "make check" output if there is an
3188 error.
3190 2006-06-06 Eric Blake <ebb9@byu.net>
3192 * tests/tools.at (automatically allowed tokens): Fix typo.
3194 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
3196 * NEWS: Don't blame non-GNU VPATH compatibility issues on Automake.
3198 * doc/autoconf.texi (Integer Overflow): Mention that INT_MIN % -1
3199 typically overflows on x86 CPUs, even though the C standard
3200 requires otherwise.
3202 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3204 * configure.ac (AC_INIT): Bump to 2.59e.
3205 * NEWS: Update.
3207 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3209 Version 2.59d.
3211 * config/texinfo.tex: Sync from upstream.
3213 * bin/autoreconf.in: Trace `LT_CONFIG_LTDL_DIR'; if it has been
3214 seen, invoke libtoolize with `--ltdl' argument.
3215 * lib/autom4te.in (Autoreconf-preselections): Adjust.
3216 * NEWS: Update.
3217 Suggested by Eric Blake.
3219 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
3221 * NEWS: Whoops! AC_FUNC_STRNLEN isn't obsolescent. Problem
3222 reported by Ralf Wildenhues.

3239 * tests/local.at (AT_CHECK_M4): New macro, almost identical
3240 to...
3241 (AT_CHECK_AUTOM4TE): ... which is now a thin wrapper around
3242 AT_CHECK_M4.
3243 (AT_CHECK_AUTOCONF): Use AT_CHECK_M4; no longer support
3244 `expout' as the last parameter.
3245 * tests/tools.at: Adapt to the above change.
3247 2006-06-04 Stepan Kasal <kasal@ucw.cz>
3249 * doc/autoconf.texi (Limitations of Usual Tools): Correct
3250 information about race-free implementations of mkdir.
3252 2006-06-04 Eric Blake <ebb9@byu.net>
3254 * bin/autoreconf.in (help): Document M4 environment variable.
3255 * bin/autoconf.as (Usage): Likewise.

3257 * doc/autoconf.texi (autom4te Invocation): Likewise.
3259 2006-06-04 Paul Eggert <eggert@cs.ucla.edu>
3261 * NEWS: GNU make now recommended for VPATH builds.
3262 Mention that some macros are now documented to be obsolescent.
3263 * doc/autoconf.texi:
3264 Prefer "current" to "modern" to describe
3265 currently-used (albeit perhaps old-fashioned) hosts.
3266 Mention which ancient features no longer need to be worried about.
3267 setgid -> set-group-ID
3268 setuid -> set-user-ID (these are the Posix terms)
3269 Fix some misuses of "only".
3270 (AC_C_BACKSLASH_A, AC_C_CONST, AC_C_PROTOTYPES):
3271 (AC_C_STRINGIZE, AC_C_VOLATILE, AC_FUNC_CLOSEDIR_VOID):
3272 (AC_FUNC_GETPGRP, AC_FUNC_LSTAT, AC_FUNC_MEMCMP):
3273 (AC_FUNC_SELECT_ARGTYPES, AC_FUNC_SETPGRP):
3274 (AC_FUNC_SETVBUF_REVERSED, AC_FUNC_STAT, AC_FUNC_STRFTIME):
3275 (AC_FUNC_STRNLEN, AC_FUNC_UTIME_NULL, AC_FUNC_VPRINTF):
3276 (AC_HEADER_DIRENT, AC_HEADER_STAT, AC_HEADER_STDC):
3277 (AC_HEADER_SYS_WAIT, AC_HEADER_TIME, AC_ISC_POSIX):
3278 (AC_PROG_GCC_TRADITIONAL, AC_STRUCT_TM):
3279 Mention that these macros are obsolescent.
3280 (Installation Directory Variables): shall -> should
3281 (File Descriptors): Mention that 0, 1, 2 might get reopened.
3282 Mention that it's now safe to use 3 and 4.
3283 (Limitations of Usual Tools): cp -r is now specified by Posix.
3284 Omit longwinded and obsolescent discussion of cp -f.
3285 Modernize discussion of expr, ls.
3286 (Limitations of Make): Modernize discussion of VPATH builds.
3287 Mention $? as a workaround in some cases.
3288 * doc/install.texi (Basic Installation):
3289 Mention "./configure; make; make install" first. Be more
3290 specific about why this file is generic. Remove unnecessary
3291 parens. Remove misleading "only". Remove obsolete advice
3292 about csh. Don't say "configure" takes awhile; say it
3293 might take a while. Suggest CFLAGS=-g rather than CFLAGS=-O2,
3294 and CC=c99 rather than CC=c89, as these are blessed by current
3295 Posix. Recommend GNU make if doing a VPATH build.
3297 2006-06-03 Paul Eggert <eggert@cs.ucla.edu>
3299 * doc/autoconf.texi: Use a consistent style "$ @kbd{...}" for
3300 examples involving shell prompts.
3302 2006-06-02 Stepan Kasal <kasal@ucw.cz>
3303 and Paul Eggert <eggert@cs.ucla.edu>
3305 * doc/autoconf.texi (Here-Documents): Add details about the
3306 pre-ksh93g bug. Reword slightly to make it clearer. Consistently
3307 use "here-documents" instead of "here documents".
3309 2006-06-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3311 * config/texinfo.tex, doc/standards.texi: Sync from upstream.
3313 2006-06-01 Paul Eggert <eggert@cs.ucla.edu>
3315 * doc/autoconf.texi (File System Conventions): Warn about ":"
3316 anywhere in directory names.
3318 2006-05-31 Paul Eggert <eggert@cs.ucla.edu>
3320 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be even more conservative
3321 about quoting the case statement, just in case.
3322 * doc/autoconf.texi (Here-Documents): Mention that the ksh bug
3323 was fixed in ksh93g; reported by Ralf Wildenhues.
3325 2006-05-31 Stepan Kasal <kasal@ucw.cz>
3327 * doc/autoconf.texi (System Services): Do not document
3328 overriding EXEEXT via ac_cv_exeext=ext.
3329 (Particular Programs) <AC_PROG_MKDIR_P>:
3330 Document that ${MKDIR_P} understands --.
3331 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Improve the
3332 comment.
3334 2006-05-31 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3336 * lib/m4sugar/m4sh.m4 (_AS_DIRNAME_PREPARE): Guard against test
3337 argument with leading hyphen. Problem reported by Paul Eggert.
3339 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
3341 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be more conservative
3342 about quoting ac_try: quote all of it, if any of it seems suspicious.
3343 This means we don't have to worry about ${ or sed any more.
3344 Also, double-quote the case statement, to work around misuses via
3345 underquoting as reported by Ralf Wildenhues in
3346 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00169.html>.
3347 (_AC_EVAL_STDERR): Revert, since evidently some packages rely on this
3348 undocumented and dangerous macro.
3349 Problem reported by Ralf Wildenhues in
3350 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00168.html>.
3352 2006-05-31 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3354 * lib/m4sugar/m4sh.m4 (_AS_DIRNAME_PREPARE): Check whether
3355 `dirname -- /' returns `/', for SunOS dirname scripts that escaped.
3356 Report by Sam Sirlin <sam@kalessin.jpl.nasa.gov>.
3358 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
3360 * lib/autoconf/general.m4: Revert AC_TRY_EVAL and AC_TRY_COMMAND,
3361 since evidently some packages rely on the old, broken behavior.
3362 Problem reported by Ralf Wildenhues in
3363 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00160.html>.
3364 (AC_TRY_EVAL, AC_TRY_COMMAND, _AC_EVAL): Go back to the
3365 pre-2006-05-26 definitions, but leave in the comments that
3366 these macros are dangerous and should not be used.
3367 (_AC_DO_ECHO): Renamed from _AC_EVAL_ECHO. All callers changed.
3368 (_AC_DO): Renamed from _AC_EVAL. All callers changed.
3369 (_AC_DO_STDERR): Renamed from _AC_EVAL_STDERR. All callers changed.
3370 (_AC_DO_VAR): Renamed from AC_TRY_EVAL.
3371 (_AC_DO_TOKENS): Renamed from AC_TRY_COMMAND.
3373 2006-05-29 Paul Eggert <eggert@cs.ucla.edu>
3375 * lib/autoconf/status.m4 (AC_OUTPUT_MAKE_DEFS): Rewrite to avoid
3376 the use of 'tr', since this is our only use of 'tr'.
3378 2006-05-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3379 and Paul Eggert <eggert@cs.ucla.edu>
3381 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE):
3382 Don't assume 'grep' works on long lines, since AIX grep doesn't.
3384 2005-05-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3386 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Do not use `grep' on
3387 the output file in the `${datarootdir}' test.
3389 2005-05-28 Stepan Kasal <kasal@ucw.cz>
3390 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3392 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If we have not seen
3393 mention of `datarootdir' in the input file(s), but literal
3394 `${datarootdir}' in the output file, and we haven't warned yet,
3395 then warn as well: the user may have (erroneously) used
3396 `AC_SUBST([mydatadir], [$datadir/my])' instead of the correct
3397 `AC_SUBST([mydatadir], ['${datadir}/my'])'.
3398 * tests/torture.at (datarootdir workaround): Extend this test.
3399 * NEWS: Update.
3401 2006-05-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3402 and Paul Eggert <eggert@cs.ucla.edu>
3404 * doc/autoconf.texi (autoheader Invocation): The first argument to
3405 `AC_DEFINE_UNQUOTED' need not be a literal. Mention the
3406 alternatives and clear up the language a bit.
3408 2006-05-27 Paul Eggert <eggert@cs.ucla.edu>
3410 * NEWS: Reword notice for AC_TRY_COMMAND, AC_TRY_EVAL,
3411 ac_config_guess, ac_config_sub, ac_configure.
3412 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
3413 Fix typo that prevented an unnecessary space from being removed.
3414 Problems reported by Ralf Wildenhues in:
3415 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00143.html
3417 2006-05-26 Paul Eggert <eggert@cs.ucla.edu>
3419 * doc/autoconf.texi (Particular Programs, Limitations of Usual Tools):
3420 Use better wording to talk about AC_PROG_MKDIR_P's thread-safety.
3421 Don't use the term "thread-safe" to talk about mkdir race
3422 conditions, since the problem is more a process than a thread
3423 issue. Problem reported by Stepan Kasal in:
3424 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00088.html
3425 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Use code that mimics
3426 the test for 'install' more closely. Look at MKDIR_P first.
3427 Look in the PATH, and at /opt/sfw/bin.
3428 Look for a 'gmkdir' program as well (Solaris 10 /opt/sfw/bin/gmkdir).
3429 Don't bother to try mkdir -p, since we already check mkdir --version;
3430 just look at the version number. (There's no easy way to check
3431 for race-free implementations.)
3432 * tests/tools.at (autoconf: subdirectories): Adjust to above
3433 changes, since MKDIR_P now might end in "/mkdir -p".
3435 * doc/autoconf.texi (autoheader Invocation): Mention that the
3436 first arg of AC_DEFINE_UNQUOTED must be a literal.
3437 Problem reported by Ben Pfaff in
3438 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00090.html>.
3440 * NEWS: Mention that AC_TRY_COMMAND and AC_TRY_EVAL may be removed.
3441 * doc/autoconf.texi (Special Chars in Variables): New section.
3442 (Preset Output Variables): Warn about special chars in CPPFLAGS.
3443 (Installation Directory Variables): Quote $(datadir) better.
3444 (Limitations of Builtins): Describe some of eval's trickiness.
3446 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Simplify quoting.
3447 * lib/autoconf/fortram.m4 (_AC_PROG_FC_V_OUTPUT): Likewise.
3448 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Put leading space
3449 in front of every arg, not just trailing args. Quote apostrophes.
3450 (_AC_EVAL_ECHO): New macro.
3451 (_AC_EVAL, AC_EVAL_STDERR): Use it. Quote arg of eval.
3452 (AC_TRY_EVAL, AC_TRY_COMMAND): Mention that these macros might get
3453 removed.
3454 (_AC_LINK_IFELSE): Use proper rule for shell continuation lines,
3455 exposed by quoting of eval argument. Put the command on line line
3456 so it logs better.
3457 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): Use eval more safely.
3458 (_AC_PATH_X, AC_PATH_X): Quote more safely.
3459 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Use eval more safely.
3460 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Don't use eval.
3461 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Minor style change.
3462 Handle special chars in prefix, ac_srcdir, ac_aux_dir.
3463 Use eval more safely.
3464 (_AC_OUTPUT_CONFIG_STATUS): Adjust to above changes.
3465 * lib/m4sugar/m4sh.m4 (AS_VAR_GET): Note that this API needs
3466 to be replaced.
3467 * tests/base.at (AC_TRY_COMMAND): Use proper rule for shell continuation
3468 lines, exposed by quoting of eval argument.
3470 2006-05-26 Stepan Kasal <kasal@ucw.cz>
3471 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3473 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Drop the
3474 initialization of `ac_cv_exeext', do not override it if it was
3475 already set, unless it was set to `no', for compatibility with
3476 Autoconf-2.13, and comment this.
3477 Do not export `ac_cv_exeext', Libtool hasn't needed this for years.
3478 (_AC_COMPILER_EXEEXT_DEFAULT): Likewise, do not export it.
3479 (_AC_COMPILER_EXEEXT_WORKS, _AC_COMPILER_EXEEXT_CROSS): Typos.
3480 * doc/autoconf.texi (Compilers and Preprocessors) <EXEEXT>:
3481 Document that this test may be overridden by setting
3482 `ac_cv_exeext'.
3484 2006-05-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3486 Revert these two patches:
3488 2006-04-06 Eric Blake <ebb9@byu.net>
3489 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_O): Inside cache
3490 check, s/ac_exeext/ac_cv_exeext/. Fixes regression introduced
3491 2006-04-01.
3493 2006-04-01 Stepan Kasal <kasal@ucw.cz>
3494 Clean up _AC_COMPILER_EXEEXT* macros.
3495 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't try to
3496 detect exeext, it will be done by _AC_COMPILER_EXEEXT_O; just set
3497 ac_file to the name of the default output file and call
3498 _AC_COMPILER_EXEEXT_WORKS. Move the definition of ac_files and the
3499 initial `rm' of the candidate files...
3500 (_AC_COMPILER_EXEEXT): ... here and simplify them. Moreover, use
3501 the same list in subsequent `rm' calls, and for the temporary
3502 redefinition of ac_clean_files; call _AC_COMPILER_OBJEXT at the end,
3503 and don't call the other _AC_COMPILER_EXEEXT_* macros directly, use...
3504 (_AC_COMPILER_EXEEXT_TESTS): ... this new macro.
3505 (_AC_COMPILER_EXEEXT_O): Don't export ac_cv_exeext, it's not needed (or
3506 no longer needed) by libtool. Make it a cache check.
3507 (_AC_COMPILER_EXEEXT_CROSS): Remove the comment, it was obviously
3508 copied here by mistake.
3509 (AC_NO_EXECUTABLES): Redefine _AC_COMPILER_EXEEXT_TESTS, not
3510 _AC_COMPILER_EXEEXT.
3511 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX, AC_PROG_OBJC): Do not call
3512 _AC_COMPILER_OBJEXT directly.
3513 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
3515 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3517 * doc/autoconf.texi (Limitations of Usual Tools) < sed (`t')>:
3518 Fix description of how the buggy `sed' works.
3520 2006-05-25 Noah Misch <noah@cs.caltech.edu>
3522 Sync from Automake:
3524 * lib/Autom4te/XFile.pm (lock): Allow EOPNOTSUPP, besides
3525 ENOLCK. Only mention `make -j' when applicable. Only raise
3526 fatal errors when `make -j' is involved. Improve error message.
3528 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3530 * doc/autoconf.texi (Here-Documents): We now know more about
3531 the variable expansion in here documents bug.
3532 Thanks to Tim Rice and Stepan Kasal.
3534 * doc/autoconf.texi (Making testsuite Scripts): Add an example
3535 how to use TESTSUITEFLAGS. Suggested by Eric Blake.
3537 2006-05-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3539 * tests/autotest.at (Multiline command from M4 expansion):
3540 No failure to be expected if the shell quotes newlines in
3541 commands in the `set -x' output. Report by Tim Rice.
3542 * THANKS: Update.
3544 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
3546 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Don't use shell
3547 expansion in the here-documents used by config.status, as that
3548 runs afoul of the Korn shell version M-12/28/93d bug described in
3549 the Autoconf manual, and this in turn causes a Coreutils 5.95 build to
3550 fail as described by Tim Rice and diagnosed by Ralf Wildenhues in
3551 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00082.html>.
3553 2006-05-23 Jim Meyering <jim@meyering.net>
3555 * lib/autoconf/functions.m4 (AC_FUNC_LSTAT_FOLLOWS_SLASHED_SYMLINK):
3556 Fix typo introduced with 2006-04-02 change. It reversed the sense
3557 of the test.
3559 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
3561 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Simplify ac_dA and
3562 ac_dB slightly, to save bytes in the script.
3563 Max out at 50 lines, rather than 96; this is more likely
3564 (though not guaranteed) to avoid obscure 'sed' failures.
3566 2006-05-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3568 * lib/autotest/general.m4 (AT_INIT): UnixWare `tr' may interpret
3569 `tr -d -' as bad option argument. Work around this by deleting
3570 an unrelated character.
3571 Report by Tim Rice <tim@multitalents.net>.
3573 2006-05-22 Paul Eggert <eggert@cs.ucla.edu>,
3574 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
3575 Stepan Kasal <kasal@ucw.cz>
3577 * doc/autoconf.texi (Particular Programs): Do not promise that
3578 we always prefer the GNU version of the program, and that we
3579 search according to PATH; both rules can have exceptions.
3580 Update description of AC_PROG_GREP, AC_PROG_EGREP, AC_PROG_FGREP,
3581 AC_PROG_SED. Move descriptions of limitations
3582 to the Limitations of Usual Tools section.
3583 (Limitations of Usual Tools) <sed>: Mention script length
3584 limitations with Solaris /usr/ucb/sed.
3585 <grep>: Fix wording for empty alternative. Mention that -c and
3586 -l should not be combined, and that -E and -F should not be
3587 combined.
3589 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
3590 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3592 * lib/autoconf/programs.m4 (AC_PROG_SED): Catch script length
3593 limits in Solaris 8 /usr/ucb/sed by testing a long script.
3595 2006-05-22 Stepan Kasal <kasal@ucw.cz>
3597 * doc/autoconf.texi (Defining Symbols): Literal parameter of
3598 AC_DEFINE is now passed to m4_pattern_allow.
3599 * NEWS: Mention that; likewise for AC_SUBST.
3600 * lib/autoconf/general.m4 (AC_DEFINE_TRACE_LITERAL): Pass
3601 the parameter to m4_pattern_allow.
3602 * tests/tools.at: Add a check for that.
3604 2006-05-22 Stepan Kasal <kasal@ucw.cz>
3606 * lib/autoconf/status.m4: Fix typos.
3608 2006-05-21 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3610 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Remove
3611 only the files that this macro generates.
3613 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
3615 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: For
3616 the HP-UX sed limitation of 99 commands, labels do not count.
3617 * lib/autoconf/status.m4 (_AC_SED_CMD_LIMIT): Mention that
3618 in the comment.
3619 (_AC_OUTPUT_HEADER): Revert the change from 2006-05-19.
3621 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
3623 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT):
3624 Import the following fix from coreutils:
3626 2006-01-13 Jim Meyering <jim@meyering.net>
3628 Invoke AC_CHECK_FUNCS(getmntent) unconditionally so that tests of
3629 $ac_cv_func_getmntent (e.g., in gl_LIST_MOUNTED_FILE_SYSTEMS) need
3630 not double-quote uses of that variable, to accommodate the rare
3631 case in which getmntent is available in none of the libraries
3632 checked. This happens at least on FreeBSD 5.0.
3634 2006-05-20 Paul Eggert <eggert@cs.ucla.edu>
3636 * lib/autoconf/general.m4 (AC_CONFIG_AUX_DIRS): Bring back
3637 ac_config_guess, ac_config_sub, and ac_configure, since evidently
3638 some other programs unwisely rely on these undocumented vars.
3639 But put in warning comments about them.
3640 Problem reported by Ralf Wildenhues in
3641 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00068.html>.
3642 * NEWS: Document that these variables are intended to go away.
3644 2006-05-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3646 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): Require AC_PROG_CXX,
3647 and set the language to C++ (analogous to the equivalent Fortran
3648 tests).
3650 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): New macro.
3651 * doc/autoconf.texi (C++ Compiler): Document it.
3652 * lib/autoconf/fortran.m4 (_AC_PROG_FC_C_O): Adjust comment.
3653 * NEWS: Update.
3655 2006-05-19 Paul Eggert <eggert@cs.ucla.edu>
3657 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Fix off-by-one bug
3658 that caused config.status to generate 100-command sed scripts; the
3659 portable limit is 99.
3661 2006-05-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3663 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Name temporary
3664 variable `ac_d' instead of `d' to avoid infringing namespace.
3665 Report by Ralf Menzel.
3667 2006-05-18 Paul Eggert <eggert@cs.ucla.edu>
3669 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Don't prepend
3670 $ac_top_build_prefix to $MKDIR_P if it's just 'mkdir -p'.
3671 * tests/tools.at (autoconf: subdirectories): New test, taken from
3672 the corresponding problem report by Ralf Wildenhues in:
3673 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00053.html
3675 * lib/autoconf/functions.m4 (AC_REPLACE_FNMATCH, AC_FUNC_FNMATCH_GNU):
3676 Quote some uses of shell variables if they might suffer unexpected
3677 globbing. This doesn't fix all instances of quoting problems that
3678 I found, just the easy ones that look safe.
3679 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR, _AC_INIT_HELP):
3680 (AC_CONFIG_AUX_DIR, AC_CONFIG_AUX_DIR_DEFAULT, AC_CONFIG_AUX_DIRS):
3681 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST, AC_CANONICAL_TARGET):
3682 (AC_CACHE_LOAD, AC_CACHE_SAVE): Likewise.
3683 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF, _AC_PATH_X_DIRECT): Likewise.

3690 2006-05-18 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3692 * bin/autoreconf.in ($help): Reword according to the manual.
3693 Suggested by Olly Betts.
3695 2006-05-17 Olly Betts <olly@survex.com> (tiny change)
3696 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3698 * bin/autoreconf.in: Pass the directory argument to
3699 `require_configure_ac'. Fix comment.
3700 * tests/torture.at (Configuring subdirectories): Expose this.
3701 Reported by Olly Betts.
3703 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3705 * lib/Automake/Configure_ac.pm, lib/Automake/Channels.pm,
3706 lib/Automake/FileUtils.pm, lib/Automake/Struct.pm: Sync from
3707 Automake as follows:
3709 * lib/Autom4te/Configure_ac.pm (find_configure_ac): Use
3710 `$configure_in' instead of `configure.in', to preserve
3711 directory component.
3713 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3715 * config/config.guess, config/config.sub, config/texinfo.tex,
3716 doc/make-stds.texi, doc/standards.texi: Sync from upstream.
3718 2006-05-14 Paul Eggert <eggert@cs.ucla.edu>
3720 * lib/autoconf/headers.m4 (AC_HEADER_STDBOOL): Fix overly-picky
3721 test for C99 conformance; (bool) 0.5 is an integer constant
3722 expression, but (bool) -0.5 is not. Problem reported by Fedor
3723 Sergeev in <http://forum.sun.com/jive/thread.jspa?threadID=96202>.
3725 2006-05-13 Paul Eggert <eggert@cs.ucla.edu>
3727 * doc/autoconf.texi (Particular Programs): AC_PROG_MKDIR_P now
3728 sets MKDIR_P, not mkdir_p, to avoid collisions with Automake.
3729 Warn about obsolete install-sh files. Remove stray sentence
3730 fragment and fix cross reference.
3731 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Don't insist on
3732 install -d; this undoes the 2006-05-10 change.
3733 (MKDIR_P): Mark with AN_MAKEVAR.
3734 (AC_PROG_MKDIR_P): Fall back on $ac_install_sh, not $INSTALL, so
3735 that we don't require $INSTALL to be thread-safe. Move comments
3736 out of generated code. Require AC_CONFIG_AUX_DIR_DEFAULT instead
3737 of AC_PROG_INSTALL. Output a message saying that we're checking
3738 mkdir -p. Set MKDIR_P rather than mkdir_p. Do special magic for
3739 MKDIR_P instead of AC_SUBST.
3740 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE, _AC_OUTPUT_CONFIG_STATUS):
3741 Special magic for MKDIR_P, too.
3742 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Remove comment that defeated
3743 a dnl.
3744 * tests/local.at (AT_CHECK_ENV): mkdir_p -> MKDIR_P.
3746 2006-05-11 Paul Eggert <eggert@cs.ucla.edu>
3748 Sync from Automake, as follows:
3750 2006-05-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3751 * config/install-sh: Initialize IFS, so field splitting isn't
3752 turned off later.
3753 * config/mkinstalldirs: Likewise.
3754 * config/missing: Remove superfluous quotes. Replace all uses of
3755 `[' by `test', for consistency, and for..
3756 * config/missing (sed_minuso, sed_output): New variables.
3757 (autom4te, help2man, makeinfo): Use them. Unifies detection of
3758 `-o FILE', `--output FILE', `--output=FILE', stricter regex.
3759 Fixes `missing' to detect `--output' for help2man. Fixes
3760 PR automake/483. Report by Dennis J. Linse.
3761 (autom4te): Document in `missing --help'.
3763 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
3765 * NEWS: New macro AC_PROG_MKDIR_P. AS_MKDIR_P is now more robust.
3766 * config/install-sh: Don't use 'path' to talk about file names,
3767 as per GNU coding standards. Close a race condition reported by Ralf
3768 Wildenhues and Stepan Kasal. There is still a race condition
3769 on hosts that predate Posix 1003.1-1992, but we can't help this.
3770 Don't mishandle weird characters like space on pre-Posix hosts.
3771 Invoke mkdir at most once per dir arg on pre-Posix hosts.
3772 * doc/autoconf.texi (Programming in M4sh): Cross-reference to
3773 AC_PROG_MKDIR_P from AS_MKDIR_P.
3774 (Limitations of Usual Tools): Cross-reference to AC_PROG_MKDIR_P
3775 from mkdir. Mention that Autoconf 2.60 install-sh is safe but
3776 earlier editions are not (including Automake 1.8.3).
3777 Do not suggest mkinstalldirs for thread-safety.
3778 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Insist on an 'install'
3779 that understands -d, so that AC_PROG_MKDIR_P can fall back on $INSTALL.
3780 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Make it more robust in the
3781 presence of special characters and race conditions.
3782 * tests/local.at (AT_CHECK_ENV): Add mkdir_p to the list of variables
3783 in Autoconf's name space.
3785 2006-05-10 Bruno Haible <bruno@clisp.org>
3786 and Paul Eggert <eggert@cs.ucla.edu>
3788 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): New macro, taken
3789 from Automake with minor changes.
3790 * doc/autoconf.texi (Particular Programs): Document AC_PROG_MKDIR_P.
3792 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
3794 * config/install-sh: Update to Automake CVS version, as follows:
3795 2006-04-25 Stepan Kasal <kasal@ucw.cz>
3796 * lib/install-sh: Simplify the expr implementation of dirname.
3797 2006-04-24 Paul Eggert <eggert@cs.ucla.edu>
3798 * lib/install-sh: Handle --, and diagnose unknown options.
3800 2006-05-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3802 * tests/Makefile.am (AUTOTEST): Use `$(MY_AUTOM4TE)' instead of
3803 `./autom4te' to create `./testsuite', since the `all' target
3804 will ensure its presence, but `installcheck' should not create
3805 the uninstalled wrappers.
3807 * tests/torture.at (Unusual Automake input files): Skip if we
3808 detect automake < 1.8.
3810 2006-05-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3812 * lib/autoconf/c.m4 (AC_PROG_CC_STDC): If ac_cv_prog_cc_stdc
3813 is set to `no', then that overrides and sets ac_cv_prog_cc_c89
3814 and ac_cv_prog_cc_c99 to `no', for backward compatibility.
3815 * NEWS: Update.
3817 2006-05-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3819 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Take care not to
3820 munge (multiple) white space and other oddities.
3821 * tests/torture.at (AT_CHECK_AC_ARG_VAR): Make sure to M4-escape
3822 single quotes in variable assignment.
3823 (AC_ARG_VAR, configure invocation): Adjust tests to expose this
3824 and similar failures by adding multiple spaces, tabs, and other
3825 special characters.
3826 Report and different test suggested by Francesco Romani
3827 <fromani@gmail.com> and Andrew Church <achurch@achurch.org>.
3829 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): When we escape
3830 single quotes, we only need to search for single quotes; this
3831 both simplifies the search pattern, and makes us less
3832 susceptible to `echo' variations for arguments not containing
3833 single quotes.
3834 (_AC_ARG_VAR_VALIDATE): Likewise.
3836 2006-05-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3838 * doc/autoconf.texi (Special Shell Variables) <IFS>: Document
3839 `$*' and IFS concatenation issue with traditional shells and
3840 bash-2.04. Report by Seanster@Seanster.com.
3842 2006-05-03 Bruno Haible <bruno@clisp.org>
3844 * doc/autoconf.texi (Limitations of Usual Tools): Identify more
3845 precisely which Mac OS X versions have the od problem.
3847 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
3849 * doc/autoconf.texi: Use @option systematically.
3851 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
3852 and Bruno Haible <bruno@clisp.org>
3854 * doc/autoconf.texi (Limitations of Usual Tools): Add a paragraph
3855 about 'od'.
3856 (Integer Overflow): Mention the special case of integer division
3857 overflow.
3859 2006-05-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3861 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Cater for
3862 traditional shells like the Solaris one that do not use the
3863 first IFS character for assembling `$*'.
3864 Prompted by a related report from autoconf_bug@nro.ca.
3866 2006-05-01 Paul Eggert <eggert@cs.ucla.edu>
3867 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3869 * doc/autoconf.texi (Limitations of Builtins, Limitations of Make):
3870 Mention more problems with the -e option.
3872 2006-04-30 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3874 * NEWS: Typo.
3875 * doc/autoconf.texi (Systemology): Mention the Heirloom Project.
3877 * doc/autoconf.texi (Introduction, Pointers): Use `@/' liberally
3878 in URLs to improve DVI formatted output (requires texinfo 4.6).
3879 (System Services, Systemology, Shellology): Likewise.
3880 (Limitations of Usual Tools): Rewrite Mac OS X example for nicer
3881 output.
3883 * doc/autoconf.texi (Fortran Compiler): Do not use `@ovar' in
3884 continuous text.
3885 (Runtime): Fix macro argument names to match description:
3886 `action-if-found' -> `action-if-true' and similarly.
3887 (Obsolete Macros): Likewise.
3888 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE): Likewise.
3889 (AC_COMPILE_IFELSE, AC_TRY_COMPILE, _AC_LINK_IFELSE)
3890 (AC_LINK_IFELSE, AC_TRY_LINK, AC_COMPILE_CHECK): Likewise.
3892 2006-04-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3894 * doc/autoconf.texi (Limitations of Make): Clean up markup.
3896 * ChangeLog: Typo.
3897 * doc/autoconf.texi (Portable Shell): Allow wrapped URLs, for
3898 DVI output.
3900 2006-04-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

3903 /bin/sh set unsorted output.
3904 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): Adjust.
3905 * tests/local.at: Likewise.
3907 2006-04-26 Paul Eggert <eggert@cs.ucla.edu>
3909 * doc/autoconf.texi (Portable C and C++, Varieties of Unportability):
3910 (Integer Overflow, Null Pointers, Buffer Overruns):
3911 (Floating Point Portability, Exiting Portably): New sections.
3912 (Writing Test Programs): Fix some langauge. Recommend exiting
3913 with status 1, not merely nonzero. Clarify exit declaration.
3914 (Run Time): Move C exit status stuff to new Exiting Portably section.
3915 (Systemology): Mention Posix and levenez. Update v7 reference.
3916 (Portable Shell): Mention the Posix shell.
3918 2006-04-25 Stepan Kasal <kasal@ucw.cz>
3920 * bin/autoconf.as (me): Replace by as_me.
3922 2006-04-25 Paul Eggert <eggert@cs.ucla.edu>
3924 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Don't use AS_ERROR,
3925 since as_me isn't set yet.
3927 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
3929 Prepare for deprecation of AS_BASENAME and AS_DIRNAME, and fix
3930 a few minor bugs in this area.
3932 * doc/autoconf.texi (Programming in M4sh): Comment out the
3933 documentation of AS_BASENAME, for now.
3934 (Shell Substitutions): Do not use AS_DIRNAME in an example.
3935 (Limitations of Builtins) <basename>: Do not refer to
3936 AS_BASENAME.
3937 * bin/autoconf.as (me): Don't use AS_BASENAME.
3938 (dir): Remove the unused variable.
3939 * lib/m4sugar/m4sh.m4 (_AS_DETECT_REQUIRED): Renamed from
3940 AS_DETECT_REQUIRED. All uses changed.

3942 All uses changed.
3943 (_AS_DETECT_BETTER_SHELL): Put ;; at the end of a case.

3945 (_AS_BASENAME_EXPR): Renamed from AS_BASENAME_EXPR. All uses changed.
3946 (_AS_BASENAME_SED): Renamed from AS_BASENAME_SED. All uses changed.
3947 (_AS_BASENAME_PREPARE): Reject implementations that cannot handle "--".
3948 (_AS_DIRNAME_PREPARE): Likewise.
3949 (_AS_DIRNAME_EXPR): Renamed from AS_DIRNAME_EXPR. All uses changed.
3950 (_AS_DIRNAME_SED): Renamed from AS_DIRNAME_SED. All uses changed.
3951 (AS_DIRNAME): Use "dirname --".
3953 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
3955 * doc/autoconf.texi (Runtime): Renamed from "Run Time". All uses
3956 of "run time" and "run-time" changed to "runtime", for consistency.

3959 * lib/autoconf/general.m4: Likewise.
3960 * lib/autoconf/headers.m4: Likewise.
3962 * doc/autoconf.texi (Run Time): Document the exit status situation
3963 with more accuracy and detail.
3965 2006-04-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3967 * doc/autoconf.texi (Introduction): The GNU Autoconf Macro
3968 Archive is not officially `GNU' any more. Update URL.
3969 (Defining Directories): Likewise
3970 * lib/autoconf/c.m4 (AC_C_RESTRICT): Update URL.
3972 2006-04-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3974 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Remove the leading
3975 newline from the `trap' code to finish `config.log'; the NetBSD
3976 /bin/sh resets the exit status after an empty command, as
3977 documented in doc/autoconf.texi.
3978 Reported by Dalibor Topic <robilad@kaffe.org>.
3980 2006-04-19 Paul Eggert <eggert@cs.ucla.edu>
3982 * doc/autoconf.texi (C Compiler): Clarify AC_C_TYPEOF.
3983 Suggested by Bruno Haible.
3985 2006-04-18 Paul Eggert <eggert@cs.ucla.edu>
3987 * configure.ac (ac_cv_sh_n_works): Don't try to test for it, since
3988 some shells (e.g., Solaris 8 /bin/sh) implement it verrrry slowly.
3989 Instead, just list the shells that we know work.
3990 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Remove 2nd arg. All uses
3991 changed. Be more cautious about the _cv_ variable.
3992 * tests/tools.at (Syntax of the shell scripts): Check the
3993 _cv_ variable once, at first, to avoid an internal autoconf error
3994 when sh -n does not work.
3996 2006-04-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3998 * lib/Autom4te/FileUtils.pm: Sync from Automake.
4000 2006-04-16 Paul Eggert <eggert@cs.ucla.edu>
4002 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Don't
4003 use ">&-" since we're only 99.999% sure that this is portable,
4004 and since the MinGW bug is fixed in a different way.
4005 * lib/autotest/general.m4 (AT_INIT): Likewise.
4007 2006-04-16 Stepan Kasal <kasal@ucw.cz>
4009 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Handle --recheck
4010 before opening config.log, to avoid hitting a bug on MinGW.
4012 2006-04-14 Paul Eggert <eggert@cs.ucla.edu>
4014 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Close
4015 AS_MESSAGE_LOG_FD before reopening it onto the log file.
4016 This works around a MinGW bug reported by Eric Paire.
4017 Make sure that all writes to the log file append to it,
4018 rather than possibly losing data.
4019 * lib/autotest/general.m4 (AT_INIT): Likewise.
4021 2006-04-14 Stepan Kasal <kasal@ucw.cz>
4023 * lib/Autom4te/FileUtils.pm (find_file): Fix a typo in the
4024 description.
4026 2006-04-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4028 * NEWS: Update.
4030 * configure.ac (AC_INIT): Bump to 2.59d.
4032 2006-04-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4034 Version 2.59c.
4036 * Makefile.maint (news-date-check): Do not require a leading `*'
4037 before the release date in NEWS.
4039 2006-04-12 Stepan Kasal <kasal@ucw.cz>
4040 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4042 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If the templates for
4043 the instantiated file do not contain the string 'datarootdir'
4044 but contain @datadir@, @docdir@, @infodir@, @localedir@, or
4045 @mandir@, replace the reference '${datarootdir}' by the value.
4046 * tests/torture.at (datarootdir workaround): New test.
4047 * NEWS: Advertise this temporary fixup.
4048 Based on a patch by Bruno Haible, reported and analyzed by
4049 Paul Eggert and Noah Misch.
4051 2006-04-12 Eric Blake <ebb9@byu.net>
4053 * tests/autotest.at (Debugging a failed test): Fix comment.
4055 2006-04-12 Stepan Kasal <kasal@ucw.cz>
4057 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): Simplify the summary of
4058 all the changes since 2006-04-07.
4060 2006-04-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4062 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): If `ln -s file1 file2'
4063 succeeded, but `ln -s file dir' failed, take care to remove the
4064 leftover target before the next test, to prevent its spurious
4065 failure; also make sure `ln file dir' works before selecting it.
4066 Thanks to Keith Marshall for pointing this out.
4067 * THANKS: Update.
4069 * lib/autotest/general.m4 (AT_INIT): Store quoted variable
4070 assignments in `at_debug_args', so that we put them correctly
4071 in the `run' script.
4072 * tests/autotest.at (Debugging a failed test): Unmark XFAIL.
4073 Reported by Eric Blake.
4075 2006-04-11 Eric Blake <ebb9@byu.net>
4077 * tests/autotest.at (AT_CHECK_AT): Add new argument, to allow
4078 top-level tests after micro-suite has been run. Used in...
4079 (Debugging a successful test, Debugging script and environment),
4080 (Debugging a failed test): ...these new tests. The first of these
4081 is fixed by...
4082 * lib/autotest/general.m4 (_AT_CREATE_DEBUGGING_SCRIPT): New
4083 macro, split out from...
4084 (AT_INIT): ...here, so that using -d also generates a run script.
4085 Document that -d inhibits top-level logging.
4086 * doc/autoconf.texi (testsuite Invocation): Document that -d only
4087 inhibits top-level logging; debug scripts are created.
4089 * lib/autotest/general.m4 (_AT_CHECK): Avoid syntax error on empty
4090 check.
4091 * tests/autotest.at (Empty test, Empty check): New test to check it.
4093 * lib/autoconf/c.m4 (AC_C_CONST, AC_C_VOLATILE): Avoid warnings
4094 from gcc.
4096 2006-04-10 Stepan Kasal <kasal@ucw.cz>
4098 * tests/mktests.sh: Use "trap '' 0", not "trap 0". Do not touch
4099 the files if a problem appears. Make the empty *.at files
4100 read-only, too. Proposed by Ralf Wildenhues.
4102 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4104 * config/Makefile.am: Add comment to force updated Makefile.in.
4106 * lib/freeze.mk: Fix typo in comment. Unlike the last, white
4107 space only patch to this file, this patch causes the Makefile.in
4108 files that include freeze.mk to be updated, and thus have a
4109 newer time stamp again, which in turn makes a pristine CVS
4110 checkout have correct time stamps.
4112 * Makefile.maint (cvs-sv): New macro, to be used..
4113 (config.guess-url_prefix, config.sub-url_prefix)
4114 (texinfo.tex-url_prefix, standards.texi-url_prefix): ..here;
4115 point to CVS text checkout of Gnulib files.
4116 (copyright-check): Bump current year.
4117 (announcement): Do not hard-wire `./announce-gen'.
4118 (cvs-update): Propagate failures of `cvs' and `move-if-change'
4119 correctly.
4120 * Makefile.cfg (executable-update): Use `chmod a+x' instead of
4121 `chmod +x'.
4122 (wget_files): Update config.guess, config.sub, texinfo.tex by
4123 `wget-update', now that their URLs work again.
4125 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
4127 * doc/autoconf.texi (Particular Types): Don't use AC_CHECK_TYPE.
4128 Problem noted by Paul D. Smith.
4130 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4132 * doc/autoconf.texi: Remove unused words from word list.
4133 * .x-sc_prohibit_atoi_atof, .x-sc_space_tab, .x-sc_sun_os_names,
4134 .x-sc_trailing_space: New files.
4136 * doc/standards.texi: Sync from gnulib.
4138 * NEWS, doc/autoconf.texi (AC_LIBOBJ vs LIBOBJS): Mark
4139 `LIBOBJDIR' as experimental.
4141 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): MSYS `ln -s' fails
4142 with a target directory; it's internally implemented as `cp'
4143 anyway, but since Autoconf advertises the possibility to use
4144 a target directory when LN_S is `ln -s', we need to find out.
4145 Reported by Rolf Ebert <rolf.ebert.gcc@gmx.de> against MSYS,
4146 analyzed by Keith Marshall <keith.marshall@total.com>.
4148 * THANKS: Update.
4150 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
4152 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Just output
4153 confdefs.h as-is. In general, if it has backslash-newline or the
4154 like, then it doesn't work either to sort or to remove empty
4155 lines.
4157 2006-04-09 Stepan Kasal <kasal@ucw.cz>
4159 * tests/Makefile.am (AUTOCONF_FILES): Fix typo in the comment.
4161 2006-04-09 Alexandre Duret-Lutz <adl@gnu.org>
4163 * lib/autom4te.in (Automake-preselections): Preselect
4164 _AM_SUBST_NOTMAKE.
4166 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>
4168 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Use '\'' for an
4169 apostrophe within a single-quoted string, as this is the usual
4170 tradition and is easier to read than '"'"'. Don't rely on the
4171 shell treating "$/" like '$/'. Use a more-consistent indenting
4172 style for the trap.
4174 2006-04-09 Eric Blake <ebb9@byu.net>
4176 * tests/autotest.at (Backquote command substitution),
4177 (Multiline backquote command substitution): Remove mistaken
4178 AT_NO_CMDSUBST from the 2006-03-14 patch, which was meant to be
4179 applied...
4180 (Parenthetical command substitution, Multiline parenthetical
4181 command substitution): here.
4183 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>

4213 AC_TYPE_INTMAX_T, AC_TYPE_INTPTR_T, AC_TYPE_LONG_DOUBLE,
4214 AC_TYPE_LONG_DOUBLE_WIDER, AC_TYPE_LONG_LONG_INT, AC_TYPE_UINT8_T,
4215 AC_TYPE_UINT16_T, AC_TYPE_UINT32_T, AC_TYPE_UINT64_T,
4216 AC_TYPE_UINTMAX_T, AC_TYPE_UINTPTR_T, AC_TYPE_UNSIGNED_LONG_LONG_INT.
4217 (C Compiler): Move AC_C_LONG_DOUBLE to ...
4218 (Obsolete Macros): here. Under AC_LONG_DOUBLE, mention
4219 AC_TYPE_LONG_DOUBLE or AC_TYPE_LONG_DOUBLE_WIDER instead.
4220 (Posix Variants): Add AC_USE_SYSTEM_EXTENSIONS.
4221 (Coding Style). Don't mention m4_expand_once.

4240 New macros.
4242 * tests/mktests.sh (ac_exclude_list, au_exclude_list): Do not
4243 use /^foo|bar$/, it does not mean /^(foo|bar)$/.
4245 2006-04-08 Stepan Kasal <kasal@ucw.cz>
4247 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Fix the wording
4248 of the warning introduced by the 2001-08-28 change.

4256 that contains braces.
4258 2006-04-07 Stepan Kasal <kasal@ucw.cz>
4260 Revert the patch from 2006-04-01 and only improve
4261 _AS_DETECT_BETTER_SHELL:
4263 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Do not optimize; do not
4264 skip nonexistent directories.
4265 (_AS_DETECT_BETTER_SHELL): The optimization is moved here--try
4266 only shell candidates which exist.
4267 (AS_UNAME): No need to give three parameters to _AS_PATH_WALK.
4268 * lib/autotest/general.m4 (AT_INIT): No need to give three
4269 parameters to _AS_PATH_WALK.
4271 2006-04-07 Stepan Kasal <kasal@ucw.cz>,
4272 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4274 * bin/autoupdate.in (handle_autoconf_patches): Change the way we
4275 distinguish m4sugar macros.
4276 * tests/tools.at (autoupdating with aclocal and m4_include):
4277 New test. Bug reported by Gary V. Vaughan <gary@gnu.org>,
4278 test case by Noah Misch <noah@cs.caltech.edu>.
4280 2006-04-07 Stepan Kasal <kasal@ucw.cz>
4282 Revert my change from 2006-03-17, in other words:
4283 * lib/m4sugar/m4sh.m4 (AS_BOURNE_COMPATIBLE): Insert BIN_SH=xpg4
4284 and DUALCASE=1.
4285 (AS_SHELL_SANITIZE): Remove DUALCASE=1.
4286 * doc/autoconf.texi (Special Shell Variables) <BIN_SH>: Say that
4287 it is set.
4289 2006-04-07 Eric Blake <ebb9@byu.net>
4291 * doc/autoconf.texi (Programming in M4sh): Document that
4292 AS_MKDIR_P exits the script on failure.
4293 * lib/autotest/general.m4: Remove redundant AS_ERROR.
4295 2006-04-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4297 * config/elisp-comp, config/install-sh, config/mdate-sh,
4298 config/missing, config/mkinstalldirs: Sync from Automake.
4300 * lib/Autom4te/FileUtils.pm, lib/Autom4te/Struct.pm: Sync
4301 from Automake.
4303 * doc/make-stds.texi: Sync from gnulib.
4305 2006-04-06 Eric Blake <ebb9@byu.net>
4307 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_O): Inside cache
4308 check, s/ac_exeext/ac_cv_exeext/. Fixes regression introduced

4312 Eric Blake <ebb9@byu.net>,
4313 Paul Eggert <eggert@cs.ucla.edu>,
4314 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4316 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): Fix the detection of
4317 whether `set' quotes correctly: redirect stderr of the tested
4318 `set', and use a subshell, for Ultrix; use `sed' instead of
4319 `grep' for zsh `set' which may write binary output; match only
4320 at the beginning of a line, to avoid false positives.
4321 In order to avoid false positives by unrelated variables with
4322 multiline content, put the dump algorithm in a subshell and
4323 unset all variables containing newlines (except some which are
4324 special to the shell). Warn about cache variables that are
4325 unset.
4327 2006-04-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4329 * config/config.guess, config/config.sub, config/texinfo.tex:

4332 * tests/mktests.sh: Reword comments.
4334 * tests/mktests.sh: Only skip internal macros starting with
4335 `_AC_' or `__AC_'. Noted by Stepan Kasal.

4338 (AC_SEARCH_LIBS, AC_REPLACE_FUNCS): Need an argument.
4339 (AC_LINKER_OPTION): Remove (renamed to _AC_LINKER_OPTION).
4340 (AC_LIST_MEMBER_OF): Likewise (renamed to _AC_LIST_MEMBER_IF).
4341 (AC_LINK_FILES): Obsoleted since (and thus AU_DEFUN'ed).
4343 * doc/autoconf.texi (Shell Substitutions): Mention the MSYS
4344 shell issue with double-quoted command substitutions of native
4345 commands.
4346 Reported to MSYS by Mark Cave-Ayland, to Autoconf by Keith
4347 Marshall.
4349 * Makefile.maint (sc_cast_of_argument_to_free): Do not fail when

4362 <tab><space> where this makes sense.
4364 2006-04-06 Stepan Kasal <kasal@ucw.cz>
4366 * tests/Makefile.am (maintainer-check-posix):
4367 s/POSIXLY_CORRECTLY/POSIXLY_CORRECT/
4369 * lib/autoconf/status.m4 (_AC_CONFIG_FOOS): Append TAGS to
4370 ac_config_<foo>s again, sometimes normalized, sometimes not.
4371 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_LINKS):
4372 (AC_CONFIG_COMMANDS): Do not do so here.
4373 (_AC_CONFIG_REGISTER_DEST): Double quote the tags in macros _AC_LIST_TAGS
4374 and_AC_LIST_TAG_COMMANDS; fixes another regression introduced by the
4375 2005-07-25 rewrite. Noticed by Noah Misch.
4377 * lib/autoconf/general.m4 (AC_PRESERVE_HELP_ORDER): Do not define
4378 _AC_PRESERVE_HELP_ORDER, ...
4379 (AC_ARG_ENABLE, AC_ARG_WITH): ... use AC_PROVIDE_IFELSE insetad.
4381 * lib/autoconf/general.m4 (AC_ARG_VAR): Do not use m4_divert_once
4382 inside m4_expand_once; it is redundant.
4384 * lib/autoconf/general.m4 (_AC_INIT_HELP): Remove the broken support
4385 for --help from Cygnus `configure.'
4387 2006-04-06 Paul Eggert <eggert@cs.ucla.edu>
4389 * doc/autoconf.texi (C Compiler): Warn about #error. Follows up
4390 on a patch proposed by Ralf Wildenhues.
4392 2006-04-05 Paul Eggert <eggert@cs.ucla.edu>
4394 * lib/autoconf/status.m4: Replace <space>''<tab> with
4395 <tab><space> where this makes sense.
4397 2006-04-05 Howard Chu <hyc@highlandsun.com> (trivial change)
4398 Noah Misch <noah@cs.caltech.edu>
4400 * lib/autoconf/general.m4 (AC_PRESERVE_HELP_ORDER): New macro.
4401 (AC_ARG_ENABLE, AC_ARG_WITH): Adjust.
4402 * doc/autoconf.texi (Help Formatting): New node.
4403 * NEWS: Announce AC_PRESERVE_HELP_ORDER.
4405 2006-04-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4407 * TODO, config/Makefile.am, lib/freeze.mk, lib/autoconf/c.m4,
4408 lib/autoconf/specific.m4, lib/autoconf/status.m4,
4409 lib/autoconf/types.m4, lib/autotest/general.m4,
4410 tests/mktests.sh, tests/torture.at: White space cleanup:
4411 remove some SPACE before TAB, or add quoting ('' or @&t@).
4413 * NEWS, TODO, bin/autoreconf.in: `filesystem' -> `file system'.
4415 * doc/autoconf.texi (Shell Substitutions): Document `^' vs. `|'.
4417 2006-04-05 Eric Blake <ebb9@byu.net>
4419 * lib/autotest/general.m4 (AT_INIT): Prep AT_*_all, so that an
4420 empty test suite works.
4421 * tests/autotest.at (Empty test suite): Remove xfail.
4423 2006-04-05 Noah Misch <noah@cs.caltech.edu>
4425 * lib/autoconf/status.m4 (_AC_CONFIG_FOOS): Do not append normalized
4426 TAGS to ac_config_<foo>s.
4427 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_LINKS): Do so here.
4428 (AC_CONFIG_COMMANDS): Append NAME to ac_config_commands without
4429 normalizing it, consistent it with previous releases.
4430 * tests/torture.at (Macro calls in AC_CONFIG_COMMANDS tags): New test.
4432 2006-04-05 Paul Eggert <eggert@cs.ucla.edu>
4434 * lib/m4sugar/m4sh.m4 (AS_BASENAME_EXPR, AS_DIRNAME_EXPR):
4435 Use simplified args that Eric Blake originally suggested.
4437 2006-04-04 Paul Eggert <eggert@cs.ucla.edu>
4439 * tests/mktests.sh: Don't use 'cat'; just read the files directly.
4440 Prefer 'sort -u' to 'sort | uniq'. Filter data before sorting it.
4441 Use 'comm' rather than N instances of grep; this also fixes a bug
4442 whereby substrings were incorrectly matched, causing us to not
4443 generate tests for AC_F77_NAME_MANGLING and AC_FUNC_LSTAT.
4444 (exclude_list): Exclude empty macros.
4445 (ac_exclude_list): Exclude AC_INCLUDES_DEFAULT.

4450 Switch from grep to awk syntax.
4451 (ac_exclude_script): Renamed from ac_exclude_egrep.
4452 (au_exclude_script): Renamed from au_exclude_egrep.
4454 2006-04-04 Noah Misch <noah@cs.caltech.edu>
4456 * lib/autoconf/general.m4 (_AC_INIT_HELP): Only `configure.in' evidences
4457 a subdirectory subject to Cygnus `configure'.
4458 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Likewise.
4460 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): Omit the bug
4461 report request when we have no AC_PACKAGE_BUGREPORT.
4463 2006-04-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4465 * THANKS: Update.

4468 generated files.
4470 * lib/autoconf/c.m4 (AC_C_INLINE): Do not skip cleanup code.
4471 (AC_C_RESTRICT): Likewise. Furthermore, add a function with a

4482 (output): Emit AC_CONFIG_SUBDIRS as needed.
4483 * tests/autoscan.at (autoscan): Remove XFAIL.
4485 2006-04-03 Noah Misch <noah@cs.caltech.edu>
4487 * lib/autoconf/general.m4 (AC_CACHE_SAVE): Use AC_MSG_NOTICE.
4489 2006-04-03 Eric Blake <ebb9@byu.net>
4491 * THANKS: Add myself.
4493 2006-04-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4495 * lib/autotest/general.m4 (AT_INIT): Add `at_testdir' to pointer
4496 to log, point to testsuite output tree.
4498 2006-04-02 Paul Eggert <eggert@cs.ucla.edu>
4500 * NEWS: AC_PROG_CC and AC_PROG_CXX no longer declare 'exit'.
4501 * doc/autoconf.texi (Function Portability): Mention that C++
4502 has trouble with 'exit'.

4504 * lib/autoconf/c.m4 (_AC_PROG_CXX_EXIT_DECLARATION):
4505 Remove; all uses removed.
4506 (AC_LANG_INT_SAVE(C), AC_C_BIGENDIAN):

4526 Clean up _AC_COMPILER_EXEEXT* macros.
4528 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't try to
4529 detect exeext, it will be done by _AC_COMPILER_EXEEXT_O; just set
4530 ac_file to the name of the default output file and call
4531 _AC_COMPILER_EXEEXT_WORKS. Move the definition of ac_files and the
4532 initial `rm' of the candidate files...
4533 (_AC_COMPILER_EXEEXT): ... here and simplify them. Moreover, use
4534 the same list in subsequent `rm' calls, and for the temporary
4535 redefinition of ac_clean_files; call _AC_COMPILER_OBJEXT at the end,
4536 and don't call the other _AC_COMPILER_EXEEXT_* macros directly, use...
4537 (_AC_COMPILER_EXEEXT_TESTS): ... this new macro.
4538 (_AC_COMPILER_EXEEXT_O): Don't export ac_cv_exeext, it's not needed (or
4539 no longer needed) by libtool. Make it a cache check.
4540 (_AC_COMPILER_EXEEXT_CROSS): Remove the comment, it was obviously
4541 copied here by mistake.
4542 (AC_NO_EXECUTABLES): Redefine _AC_COMPILER_EXEEXT_TESTS, not
4543 _AC_COMPILER_EXEEXT.
4544 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX, AC_PROG_OBJC): Do not call
4545 _AC_COMPILER_OBJEXT directly.
4546 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
4548 2006-04-01 Stepan Kasal <kasal@ucw.cz>
4550 * lib/m4sugar/m4sh.m4 (_AS_DIRNAME_PREPARE): New macro.
4551 (AS_DIRNAME): Use it.
4552 (_AS_PREPARE): Add _AS_DIRNAME_PREPARE.
4554 * tests/*.at: Remove the generated ones.
4556 2006-04-01 Stepan Kasal <kasal@ucw.cz>

5317 * lib/autoconf/c.m4 (AC_LANG_CALL(C)): Reformat to match
5318 AC_LANG_FUNC_LINK_TRY. This involves returning the value returned
5319 by the function rather than ignoring it.
5320 (AC_LANG_FUNC_LINK_TRY(C)): Call the function rather than simply
5321 comparing its address. Intel's interprocedural optimization was
5322 outsmarting the old heuristic. Problem reported by

5340 Stepan Kasal <kasal@ucw.cz>
5342 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Balance parentheses.
5343 * lib/autotest/general.m4 (AT_INIT): If the test dir already exists,
5344 make its content writable before removing it. Remove an errorneous
5345 comment from the end, where the logs of the failed tests are copied
5346 to the main log file.
5348 2005-09-27 Stepan Kasal <kasal@ucw.cz>

5355 problems if the testsuite were running too fast.
5357 2005-09-18 Paul Eggert <eggert@cs.ucla.edu>
5359 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Look for X11/Xlib.h

5371 suggested by Ben Elliston. Handle weird characters correctly.
5373 2005-09-06 Stepan Kasal <kasal@ucw.cz>
5375 * lib/autoconf/libs.m4 (AC_SEARCH_LIBS): Merge the two AC_LINK_IFELSE
5376 calls, so that the final expansion of this macro is shorter.
5377 Create the conftest.$ac_ext outside the `for' loop, to speed the run.
5378 Do not use `break' in the argument to AC_LINK_IFELSE, it would skip
5379 the cleanup there. Use AS_VAR_* macros, to be more general.
5380 * tests/semantics.at (AC_SEARCH_LIBS): Check for the cleanup.
5382 * lib/autoconf/general.m4: Use AS_IF where appropriate.
5384 * lib/m4sugar/m4sh.m4 (AS_IF): Use m4_default.

5402 2005-08-26 Stepan Kasal <kasal@ucw.cz>
5404 * doc/autoconf.texi (Programming in M4sh) <AS_TR_CPP>: Fix m4 quoting
5405 in the example. Reported by Bruno Haible.
5406 <AS_TR_SH>: Likewise. Also modify the example to be more convincing:
5407 "if $undefined_var;" succeeds with my shell.
5409 * lib/autoconf/general.m4 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST,
5410 AC_CANONICAL_TARGET): Define by AC_DEFUN, no need to use AC_DEFUN_ONCE;
5411 but change the m4_divert_text to m4_divert_once.

5421 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Simplify; rejecting
5422 some evil values and relying on the fact that $* concatenates the
5423 parameters by the first character from IFS.
5425 2005-08-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
5426 Stepan Kasal <kasal@ucw.cz>
5428 * lib/autoconf/status.m4 (_AC_CONFIG_REGISTER_DEST): When the
5429 first header appears, define AH_HEADER.
5430 * doc/autoconf.texi (Configuration Headers): Document AH_HEADER.
5431 Update limitations about when to call AC_CONFIG_HEADERS.
5432 (Configuration Commands): Document that AC_CONFIG_COMMANDS_PRE
5433 parameter can call AC_SUBST, AC_DEFINE, or AC_CONFIG_FOOS; explain
5434 that AC_CONFIG_COMMANDS_PRE and AC_CONFIG_COMMANDS_POST are not
5435 ``Configuration Actions''; fix their index entries.
5437 * lib/autotest/general.m4 (AT_INIT): Process multiple keywords
5438 options correctly. Process N-M as M-N if M is smaller than N.
5439 Process ranges correctly so that N-N will run only N.
5440 Sort and uniquify the tests that will be run. If there is more
5441 than one test, reinsert the banners for the tests.

5447 before passing the macro name to AH_TEMPLATE.
5449 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): config.status
5450 now opens log after option processing; in particular, --version
5451 and --help do not touch config.log.

5468 Prepend to LIBS, not append, in examples.
5470 2005-08-16 Stepan Kasal <kasal@ucw.cz>
5472 When building in place, set srcdir="."; suggested by Tim Van Holder.
5474 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Do this; to recognize
5475 build in place, we need ac_pwd, and thus have to AC_REQUIRE ...
5476 (_AC_INIT_DIRCHECK): ... this macro and AC_DEFUN both of them.
5477 * lib/autoconf/status.m4 (_AC_SRCDIRS): Fix a comment: srcdir="."

5491 * Makefile.maint (GZIP_ENV): When checking the help text of gzip,
5492 add "2>&1"; gzip 1.2.4 prints help on stderr.
5494 2005-07-27 Stepan Kasal <kasal@ucw.cz>
5496 * lib/autotest/general.m4 (_AT_DECIDE_TRACEABLE): The symbol at_reason
5497 was pushdef'ed twice while popped only once. Push it only once.
5498 (_AT_CHECK): Cosmetic changes to the "case $at_status" command.
5500 2005-07-26 Stepan Kasal <kasal@ucw.cz>
5502 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): The message is now
5503 prefixed by mere "===", not "configure: === ".
5505 2005-07-25 Paul Eggert <eggert@cs.ucla.edu>
5507 * Makefile.maint: Update from Bison.
5509 * lib/m4sugar/m4sugar.m4 (m4_strip): Comment fix---change tab to
5510 "<tab>" in comment, so that the point is understandable.
5512 2005-07-25 Stepan Kasal <kasal@ucw.cz>
5514 Rewrite substantial part of lib/autoconf/status.m4.
5515 The main change is that CONFIG_FILES, CONFIG_HEADERS, CONFIG_LINKS,
5516 and CONFIG_COMMANDS are not processed in four separate loops.
5517 Instead, there is one main loop. This alows that the common code
5518 is expanded only once, thus config.status (and configure) is smaller.
5520 The registration mechnism in AC_CONFIG_FILES and cousins also changed;
5521 the AC_LIST_FILES and cousins macros are no longer used.
5523 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES, _AC_OUTPUT_HEADERS,
5524 _AC_OUTPUT_LINKS, _AC_OUTPUT_COMMANDS): Renamed to ...
5525 (_AC_OUTPUT_FILE, _AC_OUTPUT_HEADER, _AC_OUTPUT_LINK,
5526 _AC_OUTPUT_COMMAND): ..., respectively. These macros no longer
5527 contain the initialization, nor the for loop, nor the associated
5528 commands; all these go to ...
5529 (_AC_OUTPUT_MAIN_LOOP): ... this new macro, called from
5530 _AC_OUTPUT_CONFIG_STATUS.
5531 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST, _AC_CONFIG_SPLIT_FILE_IN):
5532 Nuked; the code was merged into _AC_OUTPUT_MAIN_LOOP.
5533 (_AC_OUTPUT_FILE): The creation of the sed script ...
5534 (AC_OUTPUT): ... and the setup of ac_vpsub goes to ...
5535 (_AC_OUTPUT_FILES_PREPARE): ... a new macro, also called from
5536 _AC_OUTPUT_MAIN_LOOP.
5537 (_AC_CONFIG_FILES, _AC_CONFIG_HEADERS, _AC_CONFIG_LINKS,
5538 _AC_CONFIG_COMMANDS): Use ...
5539 (_AC_CONFIG_FOOS): ... this new macro, which uses these ...
5540 (_AC_CONFIG_REGISTER, _AC_CONFIG_REGISTER_DEST): ... new macros.
5541 (_AC_CONFIG_FILE, _AC_CONFIG_HEADER, _AC_CONFIG_LINK,
5542 _AC_CONFIG_COMMAND, _AC_CONFIG_DEPENDENCIES): No longer needed.
5543 (_AC_CONFIG_DEPENDENCY): Update, it uses these ...
5544 (_AC_CONFIG_DEPENDENCY_DEFAULT, _AC_FILE_DEPENDENCY_TRACE_COLON):
5545 ... new macros.
5546 (_AC_CONFIG_UNIQUE): Update.
5547 (AC_LIST_FILES, AC_LIST_HEADERS, AC_LIST_LINKS, AC_LIST_COMMANDS):
5548 Replaced by this ...
5549 (_AC_LIST_TAGS): ... new common macro.
5550 (AC_LIST_FILE_COMMANDS, AC_LIST_HEADER_COMMANDS, AC_LIST_LINK_COMMANDS,
5551 AC_LIST_COMMAND_COMMANDS): Replaced by this ...
5552 (_AC_LIST_TAG_COMMANDS): ... new common macro.
5553 (_AC_CONFIG_COMMANDS_INIT): Moved top to the `registration' section;
5554 this didn't belong to the `config commands' section.
5555 (_AC_OUTPUT_COMMANDS_INIT): Don't initialize, m4_ifdef is our friend.
5556 (AC_CONFIG_COMMANDS_PRE, AC_OUTPUT_COMMANDS_PRE,
5557 AC_CONFIG_COMMANDS_POST): Moved to a new section, these didn't belong
5558 to the `config commands' section either.
5559 (AC_CONFIG_SUBDIRS): Don't touch diversion DEFAULTS.
5560 (_AC_LIST_SUBDIRS): Don't initialize, m4_ifdef is our friend.
5562 ... and many changes to the comments nearby.
5564 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): At the end of the day,
5565 set ac_subdirs_all='_AC_LIST_SUBDIRS'.
5566 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
5567 AC_CONFIG_COMMANDS(command:input,...) is no longer allowed.
5568 (#define header templates): The comment at the top of the generated
5569 header now includes the name(s) of the source file(s).
5571 Several unrelated small changes:
5573 * lib/autoconf/general.m4 (AC_CACHE_VAL): Be didactic, quote the first
5574 parameter to AC_DIAGNOSE.
5575 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS): Likewise.
5576 (_AC_LINK_FILES_CNT): Don't AU_DEFUN this; it causes confusing messages
5577 with autoupdate; use m4_define_default inside AU_DEFUNed AC_LINK_FILES.
5578 (AC_OUTPUT): In the compatibility code, use m4_ifvaln, to be consistent
5579 with AU::AC_OUTPUT.
5580 (AU::AC_OUTPUT): Don't double-quote $2 and $3, the compatibility code
5581 in AC_OUTPUT doesn't double-quote it either.
5582 * tests/tools.at (autoupdate): AU::AC_OUTPUT no longer double-quotes the
5583 parameters.
5585 2005-07-10 Stepan Kasal <kasal@ucw.cz>
5587 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Document which
5588 versions of Portland Group compiler produce single- and double-quoted
5589 -cmdline argument. Reported by Steven G. Johnson <stevenj@fftw.org>
5590 and Ole Holm Nielsen <Ole.H.Nielsen@fysik.dtu.dk>.
5592 2005-07-07 Paul Eggert <eggert@cs.ucla.edu>
5594 * tests/local.at (AT_CONFIG_CMP): Ignore lines like "LIBS=''" too.
5595 This is a corrected version of yesterday's patch.
5597 2005-07-07 Stepan Kasal <kasal@ucw.cz>
5599 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Report the full
5600 path, too; insert a "===" to emphasize the line.

5603 ac_cv_build_alias to ac_build_alias.
5604 (AC_CANONICAL_HOST, AC_CANONICAL_TARGET): Simplify.
5606 On 2005-02-24, an unintentional AC_SUBST([CC]) was introduced; this
5607 change eliminates it. Problem reported by Alexandre Duret-Lutz.
5608 * lib/autoconf/general.m4 (_AC_ARG_VAR_PRECIOUS): Move the AC_SUBST ...
5609 (AC_ARG_VAR): ... here.
5610 (_AC_INIT_PREPARE): Call AC_SUBST for build_alias, host_alias and
5611 target_alias.
5613 Keep a list of all precious variables and process them with one simple
5614 for loop, instead of expanding all commands, or, OTOH, complicated
5615 processing of output of "set".
5616 * lib/autoconf/general.m4 (_AC_ARG_VAR_PRECIOUS): Acumulate the
5617 variable names in new macro...
5618 (_AC_PRECIOUS_VARS): ... which will be assigned to ac_precious_vars.
5619 (_AC_ARG_VAR_STORE): New macro which writes to diversion PARSE_ARGS
5620 a loop to assign all ac_env_* and ac_cv_env_* variables.
5621 (_AC_ARG_VAR_VALIDATE): Use shell variable ac_precious_vars, divert
5622 to INIT_PREPARE.
5623 (_AC_INIT_DEFAULTS): At the end, if _AC_PRECIOUS_VARS is set, assign
5624 its value to shell variable ac_precious_vars and call
5625 _AC_ARG_VAR_STORE and _AC_ARG_VAR_VALIDATE.
5626 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Don't call
5627 _AC_ARG_VAR_VALIDATE.
5629 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Move AC_LANG_PUSH(C)
5630 and the AC_SUBSTs ...
5631 (AC_INIT): ... here.
5633 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Changed the title of
5634 the ac_subst_files section in config.log.
5636 * tests/local.at (AT_CONFIG_CMP): Revert Paul's previous change.
5638 2005-07-06 Paul Eggert <eggert@cs.ucla.edu>

5645 Fix problems reported by Nicolas Joly.
5646 * tests/base.at (Input/Output): Ignore 'loading site script' chatter.
5647 * tests/local.at (AT_CONFIG_CMP): Ignore lines like "LIBS=''" too.
5648 They are generated by the Tru64 v5.1B shell.
5650 2005-07-05 Stepan Kasal <kasal@ucw.cz>
5652 Fix my changes from 2005-07-01; reported by Noah Misch.
5653 * lib/autoconf/status.m4 (_AC_CONFIG_DEPENDENCIES): Fix the
5654 description, the macro now accepts only a single tag.
5655 (_AC_CONFIG_UNIQUE): Likewise; s/AC_File/[$1]/
5657 Fix cases when the varsions of Autoconf and Autotest don't match.
5658 Reported by Noah Misch.
5659 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Set also
5660 at_top_builddir, for compatibility with older autotest.
5661 * lib/autotest/general.m4 (AT_INIT): If at_top_build_prefix
5662 is not set, use at_top_builddir, for compatibility with older
5663 versions of autoconf.
5665 2005-07-04 Paul Eggert <eggert@cs.ucla.edu>
5667 * bin/autom4te.in ($m4): Catch usages like --nesting-limit=2048.
5668 Problem reported by Patrick Welche.
5670 2005-07-03 Paul Eggert <eggert@cs.ucla.edu>
5672 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Use &, not |, in
5673 sed substitution command, so that we allow | in program prefixes
5674 and program suffixes. (& is a problem anyway; we're not fixing
5675 that here.)
5676 * lib/autoconf/status.m4 (AC_CONFIG_FILES): Likewise, for
5677 configure_input, top_builddir, srcdir, etc.
5678 * lib/autotest/general.m4 (AT_INIT): Likewise, for
5679 PATH_SEPARATOR in AUTOTEST_PATH.
5681 2005-07-02 Alexandre Duret-Lutz <adl@gnu.org>
5683 * lib/autoconf/general.m4 (AC_SITE_LOAD): Rewrite the
5684 for loop over config.site files using `set', to allow
5685 directory names containing IFS characters.

5689 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Remove the tests for
5690 directories with weird names. Apparently some people like living
5691 on the edge. However, improve the test that "pwd" actually does
5692 report a name for the working directory.

5695 2005-07-01 Stepan Kasal <kasal@ucw.cz>

5707 about #include <config.h>.
5708 (Generic Functions): Mention the Gnulib project.
5709 (Limitations of Usual Tools) <sed>: Another minor rephrasing.
5711 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Use a here
5712 document to output the default config_* lists to config.status.
5713 Don't recognize option --file, if the functionality is not there.
5714 Likewise for --header; moreover, recognize --he and --h as shortcuts
5715 for --help in that case.
5717 * lib/autoconf/status.m4: Fix the order of the "sections", so that it
5718 matches the order of execution. No code changed.

5739 * lib/autoconf/general.m4 (AC_SUBST_TRACE): New macro, to be traced
5740 instead of AC_SUBST; proposed by Alexandre Duret-Lutz.
5741 (AC_SUBST): Call it.
5742 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Call AC_SUBST_TRACE for
5743 the directory specific variables; but don't call it for configure_input.
5745 2005-06-28 Derek Price <derek@ximbiot.com>
5747 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: Reword recent
5748 addition.
5750 2005-06-23 Paul Eggert <eggert@cs.ucla.edu>
5752 * NEWS: Don't worry about spaces in bindir etc. Only srcdir and working
5753 directory have inherent problems with special characters like spaces,
5754 due to limitations in Make syntax. Problem reported by Alexandre
5755 Duret-Lutz.
5756 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Implement the above.
5757 Also, fix Tru64 porting problem with shell patterns,

5769 from Justace Clutter.
5770 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Put name of invalid
5771 variable into diagnostic. Make the diagnostic an error, not a warning,
5772 because we really don't support spaces and suchlike in dir names.
5773 (_AC_INIT_SRCDIR): Allow special characters in $ac_unique_file.
5774 Don't worry about backslashes in srcdir; it can't happen now.
5775 (_AC_INIT_PARSE_ARGS): Allow weird characters in ac_optarg.
5776 Simplify ac_optarg handling.
5777 (_AC_ARG_VAR_VALIDATE): Remove unnecessary and inconsistent quotes.

5785 (AT_CONFIG_CMP): Use sed instead of grep plumbing.
5787 * doc/autoconf.texi (Limitations of Usual Tools) <grep>: Mention
5788 that '\|' is not allowed in BREs; recommend using newline separated
5789 list of patterns instead of multiple -e options.
5791 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Remove an old comment.
5793 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Use AC_SUBST/2.
5795 2005-06-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

5799 2005-06-21 Stepan Kasal <kasal@ucw.cz>
5801 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: Document that
5802 b, t, r, w commands require single space, while : cannot have any.
5803 (Special Shell Variables): Fix sed code this in the example.
5804 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Likewise; and fix a typo.
5805 * lib/autotest/general.m4 (AT_ARG_OPTION): Fix typo in the description.
5807 * lib/m4sugar/m4sugar.m4 (m4_split): If the parameter is empty,
5808 expand to the empty list. Don't use two pairs of m4_changequote,
5809 it's not necessary.
5811 2005-06-20 Derek Price <derek@ximbiot.com>
5813 * lib/m4/programs.m4 (AC_PROG_YACC): Declare YACC & YFLAGS precious.
5815 2005-06-17 Paul Eggert <eggert@cs.ucla.edu>
5817 * lib/m4sugar/m4sh.m4 (as_awk_strverscmp): Port to Solaris /bin/awk.
5818 * doc/autoconf.texi:
5819 Don't mention Solaris versions so much, if a
5820 problem is common to all extant versions of Solaris. Say "SunOS
5821 4" instead of "SunOS" for SunOS 4.
5822 (awk): Mention more of the limitations of traditional Awk.
5823 (cat): Don't talk about cat -v.
5825 2005-06-16 Paul Eggert <eggert@cs.ucla.edu>
5827 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE): New macro.
5828 (AS_VERSION_COMPARE): New macro. The API is taken from CVS,
5829 but the implementation is entirely different and is designed
5830 to be compatible with glibc strverscmp.
5831 * tests/m4sh.at (AS_VERSION_COMPARE): New test.
5833 * doc/autoconf.texi (Limitations of Usual Tools): Mention expr bug
5834 on Mac OS X 10.4 reported by Peter O'Gorman in:
5835 http://lists.gnu.org/archive/html/autoconf-patches/2005-06/msg00041.html
5836 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT):
5837 Use shell builtins rather than 'expr', to work around expr bug.
5839 2005-06-10 Paul Eggert <eggert@cs.ucla.edu>
5841 * doc/autoconf.texi: "filesystem" -> "file system".
5842 "behaviour" -> "behavior".
5843 Warn about \(...\)* in Solaris sed (written by Ralf Menzel).
5844 * lib/autoconf/general.m4: Omit blank after ":" sed command,
5845 as per POSIX.
5846 * lib/m4sugar/m4sh.m4: Likewise.

5848 with Solaris sed. Fix by Ralf Menzel and Stepan Kasal.
5850 * man/Makefile.am (MOSTLYCLEANFILES): Add $(srcdir)/*.t.
5851 (.x.1): Ignore the time stamp in the .TH line when deciding whether
5852 to update the man page. That way, we don't have to check in new
5853 man pages every month.
5855 * lib/m4sugar/m4sh.m4 (AS_VAR_TEST_SET): Work even if $1 contains
5856 quotes and backslashes. Patch from Derek Price.
5858 2005-06-10 Derek Price <derek@ximbiot.com>
5860 * doc/autoconf.texi (Programming in M4sh): Document AS_TR_CPP &
5861 AS_TR_SH.
5863 2005-06-08 Paul Eggert <eggert@cs.ucla.edu>
5865 * lib/autotest/general.m4 (AT_INIT): Don't accept Solaris 9's diff
5866 -u, since it outputs chatter if the input files are the same.
5867 Problem reported by Ralf Menzel.
5869 2005-06-08 Derek Price <derek@ximbiot.com>
5871 * lib/m4sugar/m4sugar.m4: Undefine include & sinclude rather than
5872 renaming them since they are about to be redefined anyhow.
5874 2005-06-08 Derek Price <derek@ximbiot.com>
5876 * doc/autoconf.texi (Redefined M4 Macros): Add index entries for most
5877 redefined M4 macros to this node. Document m4_include & m4_sinclude.
5878 Move m4_undefine to alphabetical order.
5880 2005-06-07 Paul Eggert <eggert@cs.ucla.edu>
5882 * README: Recommend GNU M4 1.4.3 or later.
5883 * doc/autoconf.texi (Introduction): Likewise.
5884 Reword to avoid some formatting glitches.
5885 Use "#!/bin/sh", not "#! /bin/sh"; the space isn't needed these days.
5886 Clarify explanation of HP compiler bug.
5887 Redo example output tp match current CVS snapshot.
5888 Use @example.org in email addresses when the examples
5889 might get inadvertently cut-and-pasted into user code.
5890 Remove example of autom4te usage that doesn't seem to work now.
5891 Use modern AC_INIT (except when the example is meant to be
5892 shown with Autoconf 2.13).
5893 Update ksh info for Solaris 9 and later.
5894 KB -> kB.
5895 Modernize description of Automake versions a bit.
5896 Don't claim a future version of Autoconf is near.
5897 * doc/install.texi: Reword to avoid some formatting glitches.
5899 2005-06-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5901 * doc/autoconf.texi: Add [] to examples, so that the manual
5902 follows its own advice about quoting better.
5903 Reword to avoid some formatting glitches.
5904 * doc/installt.exi: Reword to avoid some formatting glitches.
5906 * doc/autoconf.texi (Limitations of Builtins) <case>: Mention
5907 Tru64 ksh pattern matching bug. Reported against Libtool by
5908 Albert Chin <libtool@mlists.thewrittenword.com> and
5909 Nicolas Joly <njoly@pasteur.fr>.
5911 2005-06-06 Stepan Kasal <kasal@ucw.cz>
5913 m4_cdr of one-member list was [[]] (one-member list containing an
5914 empty string) instead of [] (an empty list. Callers were skewed to
5915 match this misbehaviour. As a consequence of this:
5916 - m4_foreach([x], [], [foo]) expanded to `foo', while
5917 - the expansion of m4_foreach([x], [[]], [foo]) was empty.
5918 This bug has been fixed:
5920 * lib/m4sugar/m4sugar.m4 (m4_cdr): If only one argument is given,
5921 expand to an empty string; print error msg if called without
5922 an argument list.
5923 (m4_foreach, m4_map, m4_map_sep): Don't expect the previous
5924 misbehaviour; handle [] and [[]] correctly.
5926 2005-06-06 Stepan Kasal <kasal@ucw.cz>
5928 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Nuke ac_max_here_lines.
5929 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Simplify the sed
5930 scripts created and the loop applying them, use _AC_SED_CMD_LIMIT.
5932 2005-06-06 Ralf Menzel <menzel@ls6.cs.uni-dortmund.de> (trivial change)
5934 * doc/autoconf.texi (Limitations of Usual Tools): Solaris' awk cannot
5935 swallow records with more than 99 fields.
5936 * lib/autotest/general.m4 (AT_INIT): Use the awk builtin `split' to
5937 parse the long line.
5939 2005-06-04 Stepan Kasal <kasal@ucw.cz>
5941 * doc/autoconf.texi (Limitations of Usual Tools): AIX awk cannot
5942 swallow literals longer than 399. Reported by Ralf Wildenhues.
5943 * lib/autotest/general.m4 (AT_INIT): Pass $at_groups though stdin,
5944 to workaround this limitation.
5946 2005-06-03 Steven G. Johnson <stevenj@alum.mit.edu>
5948 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Find g95 in addition
5949 to gfortran, and make these the first two compiler names
5950 checked (following the general autoconf preference for gcc).
5952 2005-06-03 Stepan Kasal <kasal@ucw.cz>
5954 * tests/Makefile.am (check_SCRIPTS): Set to $(wrappers).
5955 (DISTCLEANFILES): Remove $(check_SCRIPTS).
5956 (testsuite): Make sure autotest.m4f is up-to-date before using it.
5958 2005-06-02 Paul Eggert <eggert@cs.ucla.edu>
5960 * lib/autotest/general.m4 (AT_INIT): Don't create a regular
5961 expression of unbounded size when processing the --list
5962 option. This runs afoul of a limit of 399 bytes per regular
5963 expression on AIX. Problem reported by Ralf Wildenhues.
5965 2005-06-01 Paul Eggert <eggert@cs.ucla.edu>
5967 * NEWS: Note yesterday's changes to AC_SUBST and AC_SUBST_FILE.
5968 * doc/autoconf.texi (Particular Headers): Reword example
5969 for multiline stdbool replacement.
5970 (Setting Output Variables): Reword text a bit. Don't
5971 give all the details about |#_!!_#|.
5972 Reword description of line replacement.
5974 2005-05-31 Dan Manthey <dan_manthey@partech.com>
5976 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Output variables may
5977 now contain newlines, and substituted files must be referenced on
5978 a line alone; the sed scripts to substitute them are now very
5979 different.
5980 (_AC_SED_CMD_LIMIT): Added; single place to store limit on how many
5981 commands can be put in a sed script portably.
5982 * doc/autoconf.texi (Setting Output Variables): Document above
5983 changes. (Particular Header Checks) <AC_HEADER_STDBOOL>: Give exaple
5984 use of multiline substitution.
5985 * tests/torture.at: No longer expect substitution of newline to fail.
5987 2005-05-27 Paul Eggert <eggert@cs.ucla.edu>
5989 * lib/m4sugar/m4sh.m4 (_AS_SHELL_FN_WORK): Fix diagnostics.
5990 From Ralf Menzel (trivial change).
5992 2005-05-25 Paul Eggert <eggert@cs.ucla.edu>
5994 * tests/local.at: Don't attempt to check for negated character
5995 classes in shell scripts. The test was too brittle.
5997 2005-05-25 Stepan Kasal <kasal@ucw.cz>
5999 * bin/autoconf.as: Don't use "shift 2"; it's not portable enough.
6000 * doc/autoconf.texi (Limitations of Builtins): Document this
6001 limitation.
6003 2005-05-24 Stepan Kasal <kasal@ucw.cz>
6005 * lib/m4sugar/m4sh.m4 (_AS_ECHO_LOG): New macro to factor out
6006 common code; used in many places in the tree.
6007 (AS_ESCAPE): Make the pattern a bit simpler; use \& insetad of \1.
6008 (_AS_ECHO_UNQUOTED): Move the macro lower; no code change.
6010 * lib/m4sugar/m4sugar.m4 (m4_ifset): Use m4_ifval.
6012 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Merge the two error
6013 messages when ac_unique_file is not found.
6014 (AC_CONFIG_MACRO_DIR): Simplify the `if' at the end.
6015 (AC_MSG_CHECKING, AC_MSG_RESULT): Put braces around the two echo
6016 commands, for consistency with AC_MSG_ERROR and such.
6018 * bin/autoconf.as: Make more use of "shift 2" in option processing.
6020 * bin/Makefile.am: Merge the two rules for creating scripts.
6022 2005-05-23 Stepan Kasal <kasal@ucw.cz>
6024 * lib/autoconf/general.m4 (AC_MSG_RESULT_UNQUOTED): Make
6025 obsolete; it was never documented.
6026 (AC_CACHE_CHECK): Use AC_MSG_RESULT instead.
6028 2005-05-20 Stepan Kasal <kasal@ucw.cz>
6030 * NEWS: @top_builddir@ is now a dirname, ac_top_builddir will follow.
6031 * lib/autoconf/status.m4 (_AC_SRCDIRS): Rename ...
6032 (ac_top_builddir): ... this ...
6033 (ac_top_build_prefix): ... to this; the old name is also kept, for
6034 backward compatibility.
6035 (ac_top_builddir_sub): New variable, without the trailing slash,
6036 always nonempty.
6037 (_AC_OUTPUT_FILES): s/@top_builddir@/$ac_top_builddir_sub/
6038 * doc/autoconf.texi (Configuration Actions): Rename
6039 ac_top_builddir to ac_top_build_prefix.
6040 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Rename
6041 at_top_builddir to at_top_build_prefix.
6042 * lib/autotest/general.m4 (AT_INIT): Likewise.
6044 2005-05-20 Stepan Kasal <kasal@ucw.cz>
6046 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Simplify the init
6047 of confdefs.h .
6049 2005-05-17 Stepan Kasal <kasal@ucw.cz>
6051 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Don't m4_quote the second
6052 argument to m4_foreach. I guess it was necessary in the past,
6053 but I think it's a no-op now.
6055 2005-05-17 Stepan Kasal <kasal@ucw.cz>
6057 * lib/autoconf/general.m4 (_AC_INIT_HELP): Merge two consecutive
6058 ``cat <<_ACEOF'' commands to one.
6059 (_AC_CANONICAL_SPLIT): Use expr, not ``echo|sed.''
6060 * lib/autoconf/status.m4: On various places, use expr instead of
6061 ``echo|sed.''
6062 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST):
6063 (_AC_CONFIG_SPLIT_FILE_IN): New macros, to factor out common code.
6064 * lib/autotest/general.m4 (AT_INIT): Use expr to get the numbers from
6065 a range.
6066 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Use awk to search for
6067 the wrong patterns between ``case'' and ``esac.'' The previous
6068 code had false positives.
6070 2005-05-14 Alexandre Duret-Lutz <adl@gnu.org>
6072 * lib/autoconf/functions.m4 (_AC_LIBOBJ_ALLOCA): Prepend ${LIBOBJDIR},
6073 as on 2005-05-02.
6074 * doc/autoconf.texi (Particular Functions) <AC_FUNC_ALLOCA>:
6075 Mention LIBOBJDIR.

6115 2005-05-13 Stepan Kasal <kasal@ucw.cz>
6117 * lib/autoconf/general.m4 (AC_CONFIG_LIBOBJ_DIR): Remove the broken
6118 check.
6119 * lib/m4sugar/m4sugar.m4 (m4_bmatch): Halt with error if we don't get
6120 enough arguments, similarly as in m4_bpatsubsts.
6122 2005-05-12 Stepan Kasal <kasal@ucw.cz>
6124 * lib/autoconf/status.m4 (_AC_SRCDIRS): Simplify the computation
6125 of absolute paths.
6127 2005-05-11 Stepan Kasal <kasal@ucw.cz>
6129 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Make the check
6130 for absolute directory names in one loop.
6131 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Handle
6132 abbreviations of --version and --debug.
6134 2005-05-10 Paul Eggert <eggert@cs.ucla.edu>
6136 * doc/autoconf.texi (Autoconf Language): Be more precise about
6137 quoting rules. Problems noted by Stepan Kasal.
6138 Also, throughout this document, be more careful about white space.
6139 "blank", "white space", and "space" all have different meanings
6140 and we should be careful to say what we mean.
6142 2005-05-05 Paul Eggert <eggert@cs.ucla.edu>
6144 Fix C++ related problems reported by Werner Lemberg.
6145 * doc/autoconf.texi (C++ Compiler): Mention .cpp extension.
6146 * lib/autoconf/c.m4 (AC_LANG(C++)): Set ac_ext to .cpp, not .cc.
6147 * lib/autoconf/types.m4 (AC_TYPE_SIGNAL): Simplify test, to
6148 avoid problems with C++ and throw.
6149 * tests/compile.at: .cpp, not .cc.
6151 * tests/semantics.at: Prepend LIBOBJDIR, as per 2005-05-02 change.
6153 2005-05-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6155 * doc/autoconf.texi (Generic Functions): Typos.
6157 2005-05-02 Gary V. Vaughan <gary@gnu.org>
6159 * lib/autoconf/general.m4 (_AC_LIBOBJS_NORMALIZE): Prepend each
6160 object named in LIBOBJS and LTLIBOBJS with the ${LIBOBJDIR}, as
6161 set by latest automake.
6163 2005-05-01 Paul Eggert <eggert@cs.ucla.edu>
6165 * doc/autoconf.texi (Limitations of Usual Tools): "expr '' \| ''"
6166 outputs 0 on GNU/Linux these days.
6168 2005-04-29 Paul Eggert <eggert@cs.ucla.edu>
6170 * doc/autoconf.texi (Autoconf Language): Add more description
6171 about quoting heuristics.
6172 (Limitations of Builtins): Describe "set -" problems.
6174 2005-04-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6176 * lib/autotest/general.m4 (AT_KEYWORDS): Separate by space,
6177 not newline.
6179 * doc/autoconf.texi (External Software): Replace AC_DEFINE_UNQUOTED
6180 by AC_DEFINE; it was a mistake.
6181 From bug reported against libtool by Dalibor Topic <robilad@kaffe.org>.
6183 2005-04-25 Stepan Kasal <kasal@ucw.cz>
6185 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): A tiny optimization.
6187 2005-04-22 Stepan Kasal <kasal@ucw.cz>
6189 * doc/autoconf.texi (External Software): Quadrigraphs are not
6190 processed correctly in AS_HELP_STRING; avoid this in the examples.
6191 * lib/m4sugar/m4sh.m4 (AS_HELP_STRING): Add a FIXME about quadrigraphs.
6192 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Likewise; and rephrase the
6193 comment and reduce m4_default([foo], []) to [foo].
6194 (m4_strip): Update the explanation.
6196 2005-04-19 Paul Eggert <eggert@cs.ucla.edu>
6198 * lib/autoconf/general.m4 (_AC_INIT_PREPARE, _AC_RUN_IFELSE):
6199 Remove core.conftest.* too; it's generated by Tru64 5.1.
6200 Problem reported by Jennis Pruett.
6201 * lib/autoconf/functions.m4
6202 (AC_FUNC_SETVBUF_REVERSED, AC_FUNC_UTIME_NULL):
6203 Don't bother to remove core files; AC_RUN_IFELSE should do that
6204 for you.
6206 2005-04-19 Stepan Kasal <kasal@ucw.cz>
6208 * lib/m4sugar/m4sugar.m4 (m4_bpatsubsts): Add the b- to comment, too.
6210 2005-04-19 Alexandre Duret-Lutz <adl@gnu.org>
6212 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Handle --docdir.
6213 Report from Horst Wente.
6215 2005-04-15 Stepan Kasal <kasal@ucw.cz>
6217 * lib/autoconf/general.m4 (_AC_ARG_VAR_VALIDATE): Fixed a typo in
6218 the comment.
6220 2005-04-14 Gregorio Guidi <greg_g@gentoo.org>
6222 * doc/autoconf.texi (External Software, Package Options): Add
6223 examples showing how to implement --with-* and --enable-* options.
6225 2005-04-13 Paul Eggert <eggert@cs.ucla.edu>
6227 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Look for configure.ac
6228 as well as configure.in. Problem reported by Gregorio Guidi.
6230 2005-04-10 Paul Eggert <eggert@cs.ucla.edu>
6232 * doc/autoconf.texi (Particular Functions): Use gnulib's current
6233 pattern for alloca snippet.
6235 2005-04-04 Stepan Kasal <kasal@ucw.cz>
6237 * lib/autotest/general.m4 (_AT_DECIDE_TRACEABLE): Fix a typo.
6239 2005-04-01 Stepan Kasal <kasal@ucw.cz>
6241 * doc/autoconf.texi (Generic Programs): Fix a typo.
6243 2005-04-01 Paul Eggert <eggert@cs.ucla.edu>
6245 * lib/autotest/general.m4 (AT_INIT): Don't assume that "date +%s"
6246 fails if %s isn't supported. Problem reported by Ralf Wildenhues.
6248 2005-03-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6250 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS):
6251 Merge `-z option' as well for the benefit of Solaris link flags. Pass
6252 whole-archive (-zallextract, -zdefaultextract) options in the hope of
6253 unique libraries, for the Sun Fortran 95 8.0 compiler. Bug reported
6254 against Libtool by Yury Puhalsky <pooh@cryptopro.ru>.
6256 2005-03-22 Paul Eggert <eggert@cs.ucla.edu>
6258 * NEWS: The configure command now warns you if you attempt to use
6259 a directory whose name contains a special character like space,
6260 newline, or "\".
6261 * doc/autoconf.texi (Installation Directory Variables): Allow
6262 "," in file names. Do not use \@; it's not a portable regexp.
6263 * bin/Makefile.am (edit): Likewise.
6264 * lib/Makefile.am (edit): Likewise.
6265 * tests/Makefile.am (edit): Likewise.
6266 * tests/semantics.at: Likewise.
6267 * tests/torture.at: Likewise.
6268 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Likewise.
6269 * lib/autoconf/status.m4 (_AC_SRCDIRS): Likewise.
6270 * doc/autoconf.texi (File System Conventions): Warn about
6271 unportable file names.
6272 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): New macro.
6273 (AC_INIT): Use it.
6274 (_AC_INIT_SRCDIR): Use ac_pwd rather than invoking pwd.
6275 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Propagate
6276 ac_pwd, and quote srcdir.
6277 * lib/autotest/general.m4 (AT_INIT): Quote file name args.
6279 * doc/autoconf.texi: Fix some systematic formatting problems.
6280 ".)" needs a following @: if not at the end of a sentence, and
6281 similarly for "!)". "etc." should be preceded by a comma.
6282 "n-th" -> "@var{n}th". pdksh is still buggy, so update its date.
6284 2005-03-22 Bruno Haible <bruno@clisp.org>
6286 * doc/autoconf.texi (Input): Mention that AC_CONFIG_AUX_DIR's
6287 argument is often called 'build-aux'.
6289 2005-03-07 Stepan Kasal <kasal@ucw.cz>
6291 * doc/autoconf.texi (Quotation Rule Of Thumb): Mention that the
6292 macro AC_TRY_LINK is obsolete.
6293 (Installation Directory Variables): Change `AC_OUTPUT_FILES' to
6294 `AC_CONFIG_FILES'.
6296 2005-02-24 Stepan Kasal <kasal@ucw.cz>
6298 * lib/autoconf/c.m4 (AC_PROG_CC): Be more careful to skip
6299 `/usr/ucb/cc'; use `cl.exe' to distinguish the MS compiler
6300 from a Common Lisp's `cl'.
6301 (AC_PROG_CXX): Behave according to the documentation: don't
6302 search for $ac_tool_prefix$CCC and $CCC, just set CXX=$CCC;
6303 make the variable CCC precious; use `cl.exe', not `cl'.
6305 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
6306 Alexandre Duret-Lutz <adl@gnu.org>
6308 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin from
6309 /dev/null, as "configure" shouldn't read stdin, and this insulates
6310 us from problems (e.g., when testing for "cl"). Also, do this
6311 redirection before invoking "hostname" or "uname", and keep the
6312 original input stream available via...
6313 (AS_ORIGINAL_STDIN_FD): ... this new macro.
6314 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't
6315 bother with "</dev/null" since it's now done at the top of
6316 'configure'.
6317 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Likewise.
6318 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
6319 * lib/autoconf/programs.m4 (_AC_PATH_PROG_FLAVOR_GNU): Likewise.
6320 * doc/autoconf.texi (File Descriptor Macros): New section.
6321 (Printing Messages): Mention it.
6322 * tests/base.at (Input/Output): New test.
6324 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
6326 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N_PREPARE): Don't set ECHO_C to
6327 newline if neither \c nor -n work, as that would output two
6328 newlines. Prefer -n to \c. Reported by Stepan Kasal.
6330 2005-02-12 Stepan Kasal <kasal@ucw.cz>
6332 * lib/m4sugar/m4sh.m4 (AS_IF): Define by m4_defun, not m4_define.
6333 This causes that any required macros inside will get before the if.
6334 * doc/autoconf.texi (autom4te.cache): A typo.
6336 2005-02-12 Paul Eggert <eggert@cs.ucla.edu>
6338 Undo previous change, except keep the change to
6339 lib/autoconf/programs.m4 that replaced grep with shell
6340 pattern-matching. This is because net-snmp configure reads stdin.
6341 Reported by Noah Misch.
6343 2005-02-11 Paul Eggert <eggert@cs.ucla.edu>
6345 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin
6346 from /dev/null, as "configure" shouldn't read stdin, and this
6347 insulates us from problems (e.g., when testing for "cl").
6348 Suggested by Alexandre Duret-Lutz. Also, do this redirection
6349 before invoking "hostname" or "uname".
6350 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
6351 _AC_LINK_IFELSE): Undo previous change, as it's no longer needed.
6352 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Don't bother with
6353 "</dev/null" since it's now done at the top of 'configure'.
6354 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
6355 * lib/autoconf/programs.m4 (_AC_PATH_PROG_FLAVOR_GNU): Likewise.
6356 Also, replace grep with shell pattern-matching, to save a process.
6358 2005-02-10 Paul Eggert <eggert@cs.ucla.edu>
6360 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
6361 _AC_LINK_IFELSE): Redirect stdin to /dev/null, in an attempt to
6362 avoid thinking that Allegro Common Lisp's "cl" command is a C++
6363 compiler.
6365 2005-02-09 Paul Eggert <eggert@cs.ucla.edu>
6367 * doc/autoconf.texi (Limitations of Usual Tools): Document that
6368 grep -q isn't portable. Improve grep -s explanation.
6369 Problem reported by Dan Manthey.
6371 2005-02-08 Paul Eggert <eggert@cs.ucla.edu>
6373 * doc/autoconf.texi (Special Shell Variables): Clarify
6374 PATH_SEPARATOR wording; fix typo in IFS. Reported by Gary V. Vaughan.

6425 * lib/m4sugar/m4sh.m4 (AS_UNAME): Try only /usr/bin/hostinfo, not
6426 any `hostinfo' in $PATH, since hostinfo.exe is a popular file name
6427 on some platforms.

6461 this fixes a bug tickled by the AT_CAPTURE_FILE change noted below.
6463 Try not to generated lines of unlimited length, as POSIX places a
6464 2047-byte limit on line length of portable text files.
6465 * lib/autoconf/general.m4 (AC_SUBST, AC_SUBST_FILE):
6466 Use newline as a separator, not space.

6469 space.

6479 * doc/autoconf.texi (Special Shell Variables): Mention _,
6480 BIN_SH, DUALCASE. Say that variables other than "status" are safe

6524 Simplify the implementation of m4_require (a.k.a. AC_REQUIRE).
6525 Update the long comment explaining it.
6527 m4_require no longer writes an ``is required by'' line to the
6528 execution stack. It contains only one bit of non-redundant
6529 information: that the macro was required, not called. And even
6530 this bit is useless in most situations: have you ever met a macro
6531 which both calls and requires the same macro?
6533 * lib/m4sugar/m4sugar.m4 (_m4_defun_pro): Don't push a diversion...
6534 (_m4_defun_pro_outer): ... only via this macro, for the outermost

6541 (_m4_require_call): Use it.
6542 * tests/m4sugar.at (m4_require): Expect output without the
6543 ``is required by'' messages.
6545 2005-01-28 Paul Eggert <eggert@cs.ucla.edu>
6547 * doc/autoconf.texi (Limitations of Usual Tools): Recommend X
6548 rather than x for expr.
6550 * lib/autoconf/lang.m4 (_AC_COMPILER_OBJEXT): Avoid subshells when
6551 this is safe.
6552 * lib/autoconf/programs.m4 (AC_PROG_EGREP, AC_PROG_FGREP): Likewise.
6553 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Likewise.

6565 from masters, so that FileUtils.pm's update_file provide --force
6566 support.
6567 * bin/autoheader.in: Pass $force to update_file so that
6568 config.h.in is always recreated when --force.

6574 2005-01-21 Paul Eggert <eggert@cs.ucla.edu>
6576 * doc/autoconf.texi (Limitations of Builtins): Clarify that
6577 "if test ! -d foo; ..." is portable. Suggested by Stepan Kasal.
6579 2005-01-20 Paul Eggert <eggert@cs.ucla.edu>
6581 * doc/autoconf.texi (Shell Substitutions): Fix typo in case statement.
6582 Warn about newline stripping in `` and $(). Update Solaris
6583 version to 9.
6584 (Limitations of Builtins): Use expr "X...", not expr "x...", as
6585 X insulates us from future changes to Posix.
6586 (Limitations of Usual Tools): For AS_DIRNAME, warn about newline
6587 stripping.
6589 2005-01-19 Stepan Kasal <kasal@ucw.cz>

6607 ulongval to be static, to avoid unwanted GCC warning. Problem
6608 reported by Michael Jennings via Daniel Reed; see
6609 <https://bugzilla.redhat.com/beta/show_bug.cgi?id=143852>.
6611 2005-01-05 Alexandre Duret-Lutz <adl@gnu.org>
6613 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Define datarootdir,

6635 (_m4_divert_n_stack): New macro; the expansion is
6636 <newline>m4_divert_stack, if m4_divert_stack is defined, and void
6637 otherwise.
6638 (m4_divert, m4_divert_push, m4_divert_pop, m4_init): Use it.
6639 (m4_divert_push, m4_divert_pop, _m4_defun_epi): Don't expand the word
6640 stored in _m4_divert_diversion or _m4_divert_dump.
6641 (m4_divert_pop): When the parameter is given, compare the symbolic
6642 name with the last diversion pushed on the stack. Previously, the
6643 current diversion was compared with the numeric value of the
6644 diversion given as the parameter.
6645 (m4_require): If the macro hasn't been expanded yet, call ...
6646 (_m4_require_call): this new macro.

6679 * bin/autoreconf.in (autoreconf_current_directory): AM_INIT_AUTOMAKE

6732 * lib/autoconf/status.m4: Quote ``$tmp'' in many places.
6733 * lib/m4sugar/m4sh.m4 (AS_TMPDIR): Fix the comment, as traps are

6860 autoscan.1, autoupdate.1, ifnames.1, config.guess.1, config.sub.1):
6861 Don't depend on .x file explicitly, since "make" does that for us.
6862 Suggested by Stepan Kasal.
6864 * bin/Makefile.am (MOSTLYCLEANFILES): Renamed from CLEANFILES.

6925 2004-12-08 Paul Eggert <eggert@cs.ucla.edu>
6927 * lib/mdate-sh: Don't use "set - x`$ls_command /`", as zsh mishandles
6928 the spaces inside $ls_command. Problem reported by Loulou Pouchet in
6929 <http://lists.gnu.org/archive/html/autoconf/2004-12/msg00074.html>.
6930 Don't use "set - x"; plain "set x" is enough, and simplifies debugging.
6932 2004-12-07 Stepan Kasal <kasal@ucw.cz>
6934 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT): Fix typo in previous

6949 with exactly one parameter.
6951 2004-12-02 Paul Eggert <eggert@cs.ucla.edu>
6953 * lib/autoconf/functions.m4 (AC_FUNC_MEMCMP): Use
6954 "char c = '\200';" rather than "char c = 0x80;" as the
6955 latter doesn't conform to the strict C standard due to
6956 overflow on signed char hosts.
6958 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Prefer -qlanglvl=extc89
6959 to -qlanglvl=ansi. We don't want to disable extensions.

6979 Automake (not without Autoconf).
6980 (Introduction): Mention lists.gnu.org.
6981 * BUGS: Don't mention bugs.gnu.org.
6982 Remove mention of ancient libtool compatibility problem.

7019 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Don't check
7020 the $1_found variable, don't test whether the file is executable;
7021 Both things are checked ...
7022 (_AC_PATH_PROG_FEATURE_CHECK): ... here; AS_EXECUTABLE_P replaces
7023 the former ``test -f''.

7026 2004-11-10 Paul Eggert <eggert@cs.ucla.edu>

7059 Problem reported by Stepan Kasal.
7061 2004-09-05 Paul Eggert <eggert@cs.ucla.edu>
7063 Fix problems reported by Andreas Buening in:

7066 in test makefile.
7067 * lib/autotest/general.m4 (AT_INIT): Don't assume /dev/null is

7070 2004-09-04 Paul Eggert <eggert@cs.ucla.edu>
7072 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): If xmkmf returns
7073 "/usr/include", clear ac_x_includes instead of leaving it as "no"
7074 (trivial change). Problem and patch reported by Andrew Church in:
7075 http://lists.gnu.org/archive/html/bug-autoconf/2004-04/msg00016.html
7077 2004-09-03 Paul Eggert <eggert@cs.ucla.edu>

7082 Also, fix some minor spacing and punctuation bugs.

7104 * Makefile.cfg (wget_files): Remove config.guess, config.sub,
7105 texinfo.tex for now (done by hand now).
7106 * Makefile.maint (wget_files, cvs_files):
7107 Remove ansi2knr.c; nobody uses it.
7108 (ansi2knr.c-url_prefix): Remove.
7109 (cvs-update): Fix test for failure. I don't know why it ever
7110 worked...
7112 * doc/autoconf.texi: Update URLs, some of which went stale.
7113 Use @uref rather than @href.
7115 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Have configure
7116 handle "--" as per POSIX. Suggested by Paul Pogonyshev.
7118 * config/config.guess, config/config.sub, config/elisp-comp,
7119 config/install-sh, config/mkinstalldirs, config/texinfo.tex,
7120 doc/fdl.texi, doc/standards.texi: Sync with master copy.
7122 * NEWS, TODO, configure.ac, bin/autoscan.in,
7123 bin/autoupdate.in, bin/ifnames.in, doc/autoconf.texi,
7124 doc/install.texi, lib/Autom4te/Configure_ac.pm,

7128 lib/m4sugar/m4sugar.m4, tests/local.at, tests/m4sh.at,
7129 tests/tools.at, tests/torture.at:
7130 Use "file name" rather than "filename" or "path",
7131 to be consistent with the terminology of the GNU coding standards.
7133 2004-08-19 Paul Eggert <eggert@cs.ucla.edu>
7135 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C),
7136 AC_C_LONG_DOUBLE): Undo 2004-06-04 change, as it didn't work with
7137 HP-UX 11.23 cc/aCC or Tru64 4.0 cc. Problem reported by Noah Misch in
7138 <http://lists.gnu.org/archive/html/autoconf/2004-07/msg00004.html>.
7140 More fixes to support spaces in the name of the build directory.
7141 This isn't a complete fix but it's an improvement.
7143 * bin/autoconf.as (autom4te_options): New var.
7144 Use it instead of appending to AUTOM4TE, so that we can allow
7145 spaces in the build directory's absolute name.
7146 * bin/autoheader.in ($autoconf): Allow spaces in file names.
7147 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP, _AT_CHECK,

7158 2004-08-12 Paul Eggert <eggert@cs.ucla.edu>
7160 * doc/autoconf.texi (Function Portability): Document isinf and
7161 and isnan. From a suggestion by Kevin Ryde.
7163 * lib/Autom4te/General.pm (END): Return correct exit status even
7164 if unlink succeeds and sets $?. Needed with Solaris 8's perl 5.00503.
7166 2004-08-09 Paul Eggert <eggert@cs.ucla.edu>
7168 * tests/torture.at (Deep Package): Use configure.in, not configure.ac,
7169 for compatibility with Automake 1.4. Reported by J C Fitzgerald in
7170 <http://lists.gnu.org/archive/html/bug-autoconf/2003-08/msg00051.html>.
7172 2004-08-04 Alexandre Duret-Lutz <adl@gnu.org>
7174 * lib/autoconf/general.m4 (AC_REQUIRE_AUX_FILE): New empty macro.
7175 (AC_CANONICAL_BUILD): Call it to require config.sub and config.guess.
7176 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Likewise for install-sh.
7177 * doc/autoconf.texi (Input): Document AC_REQUIRE_AUX_FILE.
7178 * lib/autom4te.in (Automake-preselections): Preselect
7179 AC_REQUIRE_AUX_FILE. Automake 1.10 will trace it.
7181 2004-08-02 Alexandre Duret-Lutz <adl@gnu.org>
7183 * lib/autom4te.in (Automake-preselections): Preselect
7184 AC_CANONICAL_BUILD and AC_CANONICAL_TARGET. Automake 1.9.1 will
7185 trace them.
7187 2004-07-29 Paul Eggert <eggert@cs.ucla.edu>
7189 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): Set BIN_SH, for
7190 Tru64.
7191 * doc/autoconf.texi (Shellology): Mention BIN_SH.
7192 Document problem with "`""`" in pdksh POSIX mode.
7194 2004-07-27 Paul Eggert <eggert@cs.ucla.edu>
7196 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): Use "set -o posix"
7197 with pdksh, too. Problem reported by Patrick Welche via
7198 Gary V. Vaughan.
7199 * doc/autoconf.texi (Shellology): Note that set -o posix is
7200 useful for pkdsh, too.
7202 2004-06-24 Paul Eggert <eggert@cs.ucla.edu>
7204 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Require
7205 _AS_UNSET_PREPARE, so that we can use $as_unset directly.
7206 Don't fail if ENV or BASH_ENV is readonly.
7207 (AS_SHELL_SANITIZE): Don't fail if ENV, MAIL, MAILPATH, LC_ALL,
7208 etc. are read only. Problem reported by Ludovic Courtes.

7214 (trivial change)
7216 2004-06-04 Paul Eggert <eggert@cs.ucla.edu>
7218 * doc/autoconf.texi (File System Conventions): Warn about
7219 names like "aux". Problem reported by Eric Blake.
7221 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY (C)): Use division
7222 by zero instead of array size, so that we can use any arithmetic
7223 constant expression (instead of requiring an integer constant
7224 expression). This allows us to test expressions like DBL_MAX <
7225 LDBL_MAX, which didn't conform to the C standard using the old
7226 method.
7227 (AC_C_LONG_DOUBLE): Put back in the tests for LDBL_MAX and LDBL_EPSILON,
7228 now that we can do floating-point tests at compile time.
7230 2004-06-02 Paul Eggert <eggert@cs.ucla.edu>
7232 * lib/autoconf/c.m4 (AC_C_LONG_DOUBLE): Don't check LDBL_MAX
7233 and LDBL_EPSILON, as the resulting expression isn't an
7234 integer constant expression and violates the C standard.
7235 Problem reported by Nelson H. F. Beebe. Also, check
7236 for "L" suffix, and check that long double doesn't have
7237 worse range or precision than double, that mixed-mode
7238 arithmetic doesn't generate a diagnostic, that double
7239 constants fit in long double.
7241 2004-06-03 Kevin Ryde <user42@zip.com.au>
7243 * doc/autoconf.texi (Function Portability): Add notes on free(NULL),
7244 malloc(0) and realloc(NULL,size).
7246 * doc/autoconf.texi (Shell Substitutions): Spelling error reported by
7247 Bob Proulx.
7249 2004-05-31 Paul Eggert <eggert@cs.ucla.edu>
7251 * lib/autoconf/headers.m4 (HAVE_STDBOOL_H): Detect _Bool bug
7252 in HP aC++/ANSI C B3910B A.05.55 [Dec 04 2003]. Problem reported
7253 by Jim Meyering.
7255 2004-05-26 Paul Eggert <eggert@cs.ucla.edu>
7257 * doc/autoconf.texi (Limitations of Builtins): Mention that ! COMMAND
7258 can be rewritten using if-then-else. Suggested by Bruno Haible.
7260 2004-05-25 Paul Eggert <eggert@cs.ucla.edu>
7262 * doc/autoconf.texi (testsuite Scripts): Fix typo.
7263 Problem reported by Stepan Kasal.
7265 2004-05-24 Paul Eggert <eggert@cs.ucla.edu>
7267 * tests/Makefile.am (autoconfdir): Fix to match comment (trivial
7268 change). Patch reported by Ralf Wildenhues in
7269 <http://mail.gnu.org/archive/html/bug-autoconf/2004-05/msg00092.html>.
7271 * lib/autoconf/functions.m4 (AC_FUNC_MBRTOWC): Don't assume that a
7272 function F exists if the compiler and linker let you compile an
7273 expression like (F != 0). Recent versions of GCC optimize away
7274 the reference to F in that case, since every function address must
7275 be nonzero, so the link succeeds even if F does not exist.
7276 Problem reported by Manu in
7277 <http://mail.gnu.org/archive/html/bug-gnu-utils/2004-05/msg00060.html>.
7279 * doc/autoconf.texi (Systemology): Standardize on the spelling of
7280 "Unix". Many uses changed.
7281 (Limitations of Builtins): Explain better why the ! command isn't
7282 portable.
7284 2004-05-22 Alexandre Duret-Lutz <adl@gnu.org>
7286 * lib/autom4te.in (Automake-preselections): Preselect
7287 LT_SUPPORTED_TAG in lieu of AC_LIBTOOL_TAGS.
7289 2004-05-19 Kevin Ryde <user42@zip.com.au>
7291 * doc/autoconf.texi (Function Portability): Add strerror_r, cross
7292 referencing AC_FUNC_STRERROR_R.
7294 * doc/autoconf.texi (Particular Functions): In AC_FUNC_CLOSEDIR_VOID,
7295 note pessimistic assumption when cross compiling.
7297 2004-05-16 Paul Eggert <eggert@cs.ucla.edu>
7299 * doc/autoconf.texi (Limitations of Make): Note that BSD make
7300 (until 2004) invoked subcommands with sh -e, contra POSIX.
7301 Reported by Kevin Ryde.
7303 2004-05-10 Eric Sunshine <sunshine@sunshineco.com>
7305 * programs.m4 (_AC_PROG_GREP): Fixed bug where PATH argument handed to
7306 _AC_PATH_PROG_FEATURE_CHECK contained leading whitespace (i.e.
7307 " $PATH:/usr/xpg4/bin"). This resulted in bogus tests, such as
7308 `test -f " /usr/bin/grep"', which _always_ failed.
7309 (AC_PROG_SED): Ditto bogus PATH fix.
7310 * autoconf.texi (AC_PROG_GREP): Properly document that this macro
7311 requires that grep correctly supports _multiple_ `-e' options, rather
7312 than stating only that grep should accept `-e'.
7314 2004-05-03 Paul Eggert <eggert@cs.ucla.edu>
7316 Port to C99, which requires that 'exit' be declared.
7318 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Use AC_INCLUDES_DEFAULT
7319 to ensure that stdlib.h is included.
7320 * lib/autoconf/functions.m4 (_AC_LIBOBJ_ALLOCA, AC_FUNC_SETPGRP,
7321 AC_FUNC_STRTOD, AC_FUNC_SETVBUF_REVERSED, AC_FUNC_FORK, _AC_FUNC_FORK,
7322 _AC_FUNC_VFORK, AC_FUNC_WAIT3): Likewise.
7323 * lib/autoconf/specific.m4 (AC_SYS_RESTARTABLE_SYSCALLS): Likewise.
7324 * lib/autoconf/types.m4 (AC_TYPE_GETGROUPS): Likewise.
7325 * lib/autoconf/headers.m4 (AC_HEADER_STDC): Include <stdlib.h>
7326 when using 'exit' in a test; C99 requires that 'exit' be declared.
7328 2004-05-02 Paul Eggert <eggert@cs.ucla.edu>
7330 * doc/autoconf.texi (Particular Programs): AC_PROG_GREP
7331 now prefers 'grep' implementations that accept -e.
7332 (Limitations of Usual Tools): Describe problems of traditional
7333 egrep and fgrep with long input lines, and of traditional grep
7334 with -e.
7335 * lib/autoconf/programs.m4 (AC_PROG_GREP): Check for -e, too.
7336 (_AC_PROG_GREP): Assume 3rd arg is properly quoted for the shell.
7337 All callers changed. Append /usr/xpg4/bin to the PATH, for
7338 Solaris.
7339 (_AC_FEATURE_CHECK_LENGTH): Discard stderr, so we don't bother
7340 the user with complaints about multiple -e options.
7341 * tests/local.at (AC_STATE_SAVE): Use $GREP, not grep.
7342 Define it with AC_PROG_GREP.
7343 * configure.ac (AC_PROG_GREP): Add.
7344 * lib/freeze.mk (GREP): New macro.
7346 2004-05-02 Eric Sunshine <sunshine@sunshineco.com>
7348 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Consult $SHELL as
7349 a possible candidate only after all others fail, rather than
7350 consulting it first. This improves backward compatibility by
7351 better reflecting the way shell selection occurred in previous
7352 versions of Autoconf, and should help to avoid triggering latent
7353 problems in other packages, such as the one in Automake where zsh
7354 is not handled robustly:
7355 http://mail.gnu.org/archive/html/automake/2004-04/msg00095.html
7356 Although it is not Autoconf's responsibility to work around
7357 problems in Automake, it nevertheless makes sense to avoid
7358 introducing unnecessary incompatibilites.
7360 2004-04-22 Albert Chin-A-Young <china@thewrittenword.com>,
7361 Gary V. Vaughan <gary@gnu.org>
7363 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Don't guess
7364 how deeply nested we are when a suitable tool is found, set the
7365 ac_path_TOOL_found flag.
7366 (_AC_PATH_PROG_FEATURE_CHECK): Encapsulate knowledge of how deeply
7367 nested we are in this macro. Break out of all 3 nested loops if
7368 ac_path_TOOL_found is set.
7370 2004-04-21 Gary V. Vaughan <gary@gnu.org>
7372 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Break out
7373 of the _AS_PATH_WALK loop too if GNU flavor is found.
7375 2004-04-21 Alexandre Duret-Lutz <adl@gnu.org>
7377 * doc/autoconf.texi (Limitations of Make): Update documentation
7378 for `$<'. New entry `Long lines', based on a report from Simon
7379 Josefsson. Augment the documentation for SHELL = @SHELL@ with a
7380 paragraph about DJGPP, based on a mail from Richard Dawe.
7382 2004-04-20 Paul Eggert <eggert@twinsun.com>
7384 * tests/c.at (C keywords): Don't assume that GCC supports
7385 "restrict" and "inline", as sufficiently-old GCC versions do not
7386 (also, GCC configured to be in pedantic C89 mode does not).
7387 Problem reported by Sumit Pandya in:
7388 http://mail.gnu.org/archive/html/autoconf/2004-04/msg00092.html
7390 * lib/autoconf/c.m4 (_AC_PROG_CC_G, _AC_PROG_CXX_G): Don't
7391 consider -g to work if it generates warnings when plain compiles
7392 don't. Problem reported by Braden McDaniel in:
7393 http://mail.gnu.org/archive/html/autoconf-patches/2003-07/msg00014.html
7395 * doc/autoconf.texi (Slashes): New section, to document a problem
7396 reported by Jim Meyering in:
7397 http://mail.gnu.org/archive/html/bug-coreutils/2004-02/msg00060.html
7399 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Remove potential
7400 linker output files before linking, to work around IRIX 6 linker bug.
7401 Problem reported by Rainer Orth in:
7402 http://mail.gnu.org/archive/html/autoconf-patches/2004-02/msg00007.html
7404 2004-04-20 Gary V. Vaughan <gary@gnu.org>
7406 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Make the
7407 best tool so far counter rely on the tool path variable name to
7408 avoid checks for one tool being affected by the results of running
7409 the length check on a previous tool.
7411 * lib/autoconf/programs.m4 (_AC_PROG_GREP): Take an additional
7412 match expression argument, as different greps have different
7413 regular expression flavours.
7414 (AC_PROG_FGREP): Pass 'FGREP'. fgrep treats all match chars as
7415 literals.
7416 (AC_PROG_EGREP): Pass 'EGREP$'.
7417 (AC_PROG_GREP): Pass 'GREP$'.
7419 2004-04-20 Albert Chin-A-Young <china@thewrittenword.com>
7421 * lib/autoconf/programs.m4 (AC_PROG_GREP): Cache variable
7422 is `ac_cv_path_GREP', not `oc_cv_path_GREP'.
7424 2004-03-29 Paul Eggert <eggert@twinsun.com>
7426 * doc/autoconf.texi (Particular Headers, Particular Types, Generic
7427 Types, Specific Compiler Characteristics, System Services,
7428 Obsolete Macros): Use 'long int', 'short int', 'unsigned int'
7429 etc. consistently instead of 'long', 'short', 'unsigned' etc.
7430 * lib/autoconf/c.m4 (AC_LANG_INT_SAVE(C), AC_C_BIGENDIAN): Likewise.
7431 * lib/autoconf/functions.m4 (AC_FUNC_MMAP, AC_FUNC_SELECT_ARGTYPES):
7432 Likewise.
7433 * lib/autoconf/headers.m4 (AC_HEADER_SYS_WAIT): Likewise.
7434 * lib/autoconf/types.m4 (AC_TYPE_GETGROUPS, AC_TYPE_SIZE_T,
7435 AC_TYPE_OFF_T): Likewise.
7436 * tests/semantics.at (AC_CHECK_TYPES: backward compatibility):
7437 Likewise.
7439 * tests/foreign.at (Libtool): Create an empty aclocal.m4, to
7440 pacify libtool 1.5.2. Fix quoting problems in sed command.
7442 2004-03-28 Paul Eggert <eggert@twinsun.com>
7444 * doc/autoconf.texi (Particular Structures): AC_STRUCT_TIMEZONE
7445 now defines HAVE_DECL_TZNAME if it is declared, when
7446 HAVE_STRUCT_TM_TM_ZONE is not defined.
7447 * lib/autoconf/types.m4 (AC_STRUCT_TIMEZONE): Implement this.
7448 Do not assume atoi. Rely on HAVE_DECL_TZNAME when testing
7449 for HAVE_TZNAME.
7451 2004-03-28 Steven G. Johnson <stevenj@fftw.org>
7453 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Corrected
7454 superfluous backslashing of quotes (") in sed expressions;
7455 thanks to Paul Eggert.
7457 2004-03-26 Steven G. Johnson <stevenj@alum.mit.edu>
7459 * lib/autoconf/fortran.m4 (_AC_PROG_FC): new name of Intel
7460 Fortran compiler is ifort, also added pghpf; thanks to Nelson
7461 H. F. Beebe for the bug report.
7463 2004-03-26 Steven G. Johnson <stevenj@fftw.org>
7465 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): fix for
7466 quoted -cmdline argument in Portland Group compiler (bug
7467 reported by Jeffrey J. Barteet).
7469 2004-03-25 Kevin Ryde <user42@zip.com.au>
7471 * doc/autoconf.texi (Specifying Names): Move cross_compiling ovindex to
7472 (Run Time): ... here, where it's now mentioned.

7476 * doc/autoconf.texi (autom4te Invocation): Language Autoconf
7477 inherits from language Autoconf-without-aclocal-m4.
7478 (Customizing autom4te): Adjust example; the cache must now be
7479 disabled for language Autoconf-without-aclocal-m4.
7481 2004-03-16 Paolo Bonzini <bonzini@gnu.org>
7482 Nathanael Nerode <neroden@twcny.rr.com>

7492 in the behavior of AC_PATH_TOOL, AC_CHECK_TOOL and
7493 AC_CHECK_TOOLS.
7494 (Specifying Names): Document the reason for these future
7495 behavioral changes.
7496 * tests/mktests.sh: Do not generate tests for the
7497 new macros.
7498 * NEWS: Document these changes.
7500 * doc/autoconf.texi: Avoid macros with unbraced arguments,
7501 they make TeX hang up.

7505 * NEWS: New macro AC_CHECK_ALIGNOF.
7506 * doc/autoconf.texi (Generic Compiler Characteristics): Document it.
7507 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Use long int rather than
7508 int; avoid "a `$1'" since this isn't grammatical if $1 begins with a
7509 vowel.
7510 (AC_CHECK_ALIGNOF): New macro.
7511 * tests/mktests.sh (ac_exclude_list): Exclude AC_CHECK_ALIGNOF.
7512 * tests/semantics.at (AC_CHECK_ALIGNOF): Add tests similar to
7513 those for sizeof.
7515 2004-03-03 Paul Eggert <eggert@twinsun.com>
7517 * bin/Makefile.am (edit): Don't use $< in a context where
7518 POSIX doesn't require support for it. Use $@.in instead.
7519 Problem reported by Anthony N. Frasso in
7520 <http://mail.gnu.org/archive/html/autoconf/2004-03/msg00008.html>.
7521 * bin/autoscan.in, bin/autoupdate.in: Add @configure_input@ comment.
7523 2004-02-23 Gary V. Vaughan <gary@gnu.org>
7525 * bin/autoreconf.in (autoreconf_current_directory): Recognize LT_INIT
7526 from the next generation of Libtool.
7527 * lib/autom4te.in (Autoreconf-preselections): Ditto.
7529 2004-02-20 Alexandre Duret-Lutz <adl@gnu.org>
7531 * doc/autoconf.texi (Limitations of Usual Tools) <mkdir>: `mkdir -p'
7532 is not always thread-safe. Report from Nathanael Nerode.
7534 2004-02-18 Paul Eggert <eggert@twinsun.com>
7536 Fix a dependencies problem, stemming from a Autoconf 2.59 build
7537 problem on QNX reported by Stephen Rasku in
7538 <http://mail.gnu.org/archive/html/bug-autoconf/2004-02/msg00066.html>.
7540 * bin/Makefile.am ($(srcdir)/autoconf.in): Depend on
7541 $(m4sh_m4f_dependencies); this removes a FIXME.
7542 * tests/Makefile.am ($(srcdir)/wrapper.in): Likewise.
7543 (MAINTAINERCLEANFILES): Split into pieces,
7544 one per related section. Add $(srcdir)/wrapper.in.
7546 2004-02-09 Paul Eggert <eggert@twinsun.com>
7548 * doc/autoconf.texi (Setting Output Variables): Emphasize that
7549 AC_SUBST provides no portable way to escape literal newlines.
7551 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS): Ignore all
7552 flags of the form -lcrt*.o, not just -lcrt[01].o and -lcrtbegin.o.
7553 Darwin uses -lcrt2.o and there's little point to cataloging all
7554 the system variants. Partial fix reported by Andreas Waechter in:
7555 http://mail.gnu.org/archive/html/autoconf-patches/2004-02/msg00006.html
7556 for bug reported by Nelson H. F. Beebe in:

7559 2004-02-04 Paolo Bonzini <bonzini@gnu.org>
7561 * doc/autoconf.texi (AU_DEFUN): Fix English,
7562 suggested by Paul Eggert.
7563 * lib/autoconf/autoupdate.m4: Correct reference to
7564 acobsolete.m4, suggested by Alexandre Duret-Lutz.
7566 2004-02-02 Paolo Bonzini <bonzini@gnu.org>

7569 refer to the correct file.
7570 * doc/autoconf.texi (AU_DEFUN): Describe more correctly
7571 the behavior of the third argument.
7572 * lib/autoconf/autoupdate.m4 (AU_DEFUN): Describe more
7573 correctly the behavior of the third argument. Document
7574 what the three macros that AU_DEFUN defines do. Fix
7575 warning message when the third argument includes $0
7576 (reported by Alexandre Duret-Lutz).
7578 2004-01-30 Paolo Bonzini <bonzini@gnu.org>
7579 Eric Sunshine <sunshine@sunshineco.com>
7580 Paul Eggert <eggert@twinsun.com>
7582 * lib/m4sugar/m4sh.m4 (M4SH-SANITIZE): New diversion.
7583 (AS_INIT): Output shell initialization there. Removed optional
7584 parameter. Expand _AS_SHELL_FN_SPY.
7585 (AS_INIT_WITH_SHELL_FN): Removed.
7586 (_AS_SHELL_FN_SPY): New macro.
7587 (AS_DETECT_REQUIRED, AS_DETECT_SUGGESTED): New
7588 macros.
7589 (AS_SHELL_SANITIZE): Remove loop to find better shell
7590 and documentation for the parameter.
7591 (_AS_DETECT_BETTER_SHELL): Move it here.
7592 (_AS_SHELL_FN_WORK): Remove shell invocation, reformat.
7593 (_AS_RUN): Move it here, support testing with eval.
7594 (AS_REQUIRE_SHELL_FN): Require shell functions when
7595 it is used.
7596 (_AS_LINENO_WORKS): Put around braces, we do not
7597 trigger the bash bug anymore.
7598 * lib/autotest/general.m4: Document M4SH-SANITIZE, do not
7599 use AS_INIT_WITH_SHELL_FN.
7600 * bin/autoconf.in, tests/wrapper.in: Regenerated.
7602 2004-01-30 Paolo Bonzini <bonzini@gnu.org>
7604 * bin/autoupdate.in: Trace AU_DEFINE instead of AU_DEFUN.

7619 * lib/autoconf/status.m4: Remove FIXME.
7620 * tests/local.at (AT_CHECK_AU_MACRO): Ignore stderr, check
7621 that the macro is not present anymore in the updated
7622 configure.ac.
7623 * tests/tools.at (autoupdate AC_LINK_FILES): Ignore stderr
7624 of autoupdate.

7629 copyright years.
7630 * lib/autoconf/general.m4 (_AC_INIT_COPYRIGHT): Add 1992 thorugh
7631 2003 (except 1997) to the list of copyright years. This undoes
7632 the 2003-05-22 change, which removed the older years from the list.
7633 * lib/autoconf/status.m4 (AC_OUTPUT): Update copyright date to 2004.
7635 2004-01-27 Gary V. Vaughan <gary@gnu.org>

7641 * lib/autoconf/programs.m4 (_AC_PROG_GREP): Factor out the core of
7642 AC_PROG_GREP.
7643 (AC_PROG_EGREP, AC_PROG_FGREP): Use it to find best available
7644 egrep and fgrep respectively if $GREP -E/-F don't work.
7645 (_AC_PATH_PROG_FEATURE_CHECK): Factor out the common core of
7646 _AC_PROG_GREP, and AC_PROG_SED.
7647 (_AC_FEATURE_CHECK_LENGTH): New helper macro for finding the
7648 longest input length accepted by a command.
7649 (AC_PROG_SED): Use it.
7650 * doc/autoconf.texi (Particular Programs): Document the changes.
7651 * NEWS: Updated.
7653 2004-01-27 Paul Eggert <eggert@twinsun.com>

7660 * Makefile.in, aclocal.m4, configure, bin/Makefile.in,
7661 bin/autoconf.in, config/Makefile.in, config/config.guess,

7675 sources.
7677 2004-01-26 Paul Eggert <eggert@twinsun.com>
7679 * doc/autoconf.texi (Default Includes): Include <stdint.h> even if
7680 HAVE_INTTYPES_H is defined. This is needed on Tru64 5.1b with
7681 Compac C V6.5-207 (dtk), which defines uintmax_t in <stdint.h> but
7682 not <inttypes.h>. Problem reported by Tim Mooney in
7683 <http://mail.gnu.org/archive/html/bug-coreutils/2004-01/msg00147.html>.
7684 * lib/autoconf/headers.m4 (_AC_INCLUDES_DEFAULT_REQUIREMENTS):
7685 Likewise.
7687 * lib/autoconf/programs.m4 (AC_PROG_SED): Use diff, not sed;
7688 otherwise "make check" fails because it forbids cmp (I guess
7689 because cmp treats files as binary on DOS-like systems).
7691 * tests/mktests.sh: Update copyright date to 2004, since some tests
7692 have changed in 2004.
7694 2004-01-23 Gary V. Vaughan <gary@gnu.org>
7696 * lib/autoconf/programs.m4 (AC_PROG_SED): New macro to test for a
7697 non-truncating sed or gsed program in PATH.
7698 * tests/acprograms.at: Add it.
7699 * doc/autoconf.texi (Particular Programs): Document it.
7700 * NEWS: Updated.
7702 2004-01-15 Paul Eggert <eggert@twinsun.com>
7704 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Try -std, not -std1, since
7705 -std1 disables some useful extensions on Tru64. Problem reported
7706 by N. Lichtmaier in
7707 <http://mail.gnu.org/archive/html/autoconf/2004-01/msg00100.html>.
7709 2004-01-14 Paul Eggert <eggert@twinsun.com>
7711 * doc/autoconf.texi (Programming in M4sh): Document that
7712 AS_MKDIR_P succeeds if the destination is a symbolic link
7713 to an existing directory.
7714 (Limitations of Usual Tools): Note that mkdir -p might not
7715 succeed on symlinks to directories.

7733 2004-01-09 Paul Eggert <eggert@twinsun.com>
7735 * lib/autoconf/general.m4: Fix bug: AC_CHECK_SIZEOF evokes a warning
7736 with `autoconf -Wall,error'. Bug reported by Eric Blake in:
7737 http://mail.gnu.org/archive/html/autoconf-patches/2004-01/msg00000.html
7738 (_AC_COMPUTE_INT_COMPILE): Invoke _AC_COMPILE_IFELSE, not
7739 AC_COMPILE_IFELSE, since we now assume our caller invokes
7740 AC_LANG_COMPILER_REQUIRE, for symmetry with _AC_COMPUTE_INT_RUN.
7741 (_AC_COMPUTE_INT_RUN): Likewise, for _AC_RUN_IFELSE instead
7742 of AC_RUN_IFELSE; this avoids the warning mentioned above.
7743 (_AC_COMPUTE_INT): Invoke AC_LANG_COMPILER_REQUIRE.
7745 2004-01-07 Paul Eggert <eggert@twinsun.com>
7747 * lib/autoconf/general.m4 (_AC_LIBOBJS_NORMALIZE): Avoid \$ inside
7748 `"'...'"`, as it's confusing (and I suspect it may not work on
7749 some platforms). The code was incorrect anyway, as it assumed
7750 that \$ evaluated to itself in that context. Reported by
7751 Alexandre Duret-Lutz.
7753 2004-01-07 Alexandre Duret-Lutz <adl@gnu.org>

7799 srcdir): Likewise.
7800 * doc/autoconf.texi (Limitations of Usual Tools):
7801 Warn against "rm -fr".

7805 * doc/autoconf.texi (Limitations of Usual Tools): Mention that cc
7806 -c -o might not work. From a suggestion by Kevin Ryde.
7807 (C Compiler, Generating Sources, Limitations
7808 of Usual Tools, Limitations of Make, Making testsuite Scripts):
7809 Don't put '-o' after non-options, as POSIX doesn't allow this.
7810 Mention that cc's name might be gcc or c89 or whatever.
7812 2004-01-04 Kevin Ryde <user42@zip.com.au>
7814 * doc/autoconf.texi: Add various further index entries.
7816 2003-12-29 Paul Eggert <eggert@twinsun.com>

7821 2003-12-27 Alexandre Duret-Lutz <adl@gnu.org>
7823 * doc/autoconf.texi (Limitations of Make) <Automatic rule rewriting>:
7824 Documents OSF1/Tru64 make behavior. Replace `VPATH = ../src' by

7863 functions work.
7864 (_AS_LINENO_WORKS): Don't find another shell if $LINENO
7865 does not work.
7866 (AS_INIT): Pass parameter down to AS_SHELL_SANITIZE.

7881 them on the fly.
7883 2003-11-24 Akim Demaille <akim@epita.fr>
7885 * doc/autoconf.texi (Particular Programs): AC_PROG_LEX can

8215 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Set DUALCASE=1, for MKS sh.
8216 Problem reported by Lars J. Aas in
8217 <http://mail.gnu.org/archive/html/autoconf/2003-07/msg00042.html>.
8218 (_AS_MKDIR_P_PREPARE): Change "rm -fr ./-p" to the more-conservative
8219 "test -d ./-p && rmdir ./-p". Suggested by Andreas Schwab in:
8220 http://mail.gnu.org/archive/html/autoconf-patches/2003-09/msg00039.html
8222 2003-09-26 Akim Demaille <akim@epita.fr>
8224 * lib/autoconf/status.m4 (_AC_OUTPUT_COMMANDS): Make sure the
8225 directory for AC_CONFIG_COMMANDS' first argument exists.
8226 This makes valid the invocation of _AC_SRCPATH that follows.
8227 Reported by Eric Sunshine.
8228 * doc/autoconf.texi (Configuration Commands): Adjust.
8230 2003-09-26 Akim Demaille <akim@epita.fr>
8232 * bin/autoscan.in (Autom4te::FileUtils): Use it for find_file.
8233 Reported by Ralf Corsepius.
8235 2003-09-26 Akim Demaille <akim@epita.fr>
8237 * lib/autoconf/general.m4 (AC_HELP_STRING): Don't overquote the
8238 arguments.
8239 Actually, use AU_ALIAS.
8240 From Bruno Haible.
8242 2003-09-26 Paul Eggert <eggert@twinsun.com>
8244 * lib/m4sugar/m4sh.m4 (_AS_MKDIR_P_PREPARE): If mkdir -p . fails,
8245 rm -fr ./-p to remove junk left behind on NextStep and OpenStep.
8246 Problem reported by Eric Sunshine in:

8251 The test suite are sometimes assigning timings incorrectly.
8252 Reported by Henk Krus.
8253 Diagnosed by Nicolas Joly.
8255 * lib/autotest/general.m4 (AT_CLEANUP): Rename AT_help as
8256 AT_help_all.
8257 Instead of making AT_help a sequence of assignments to grow
8258 $at_help_all, just make AT_help_all be the growing contents of
8259 $at_help_all, and make a single assignment in...
8260 (AT_INIT): here.
8261 (at_times_skip): Flip the meaning and rename as...
8262 (at_times_p): this.
8263 (AT_INIT): When summarizing the test that ran, remove
8264 $at_times_file after use, and check it is present before trying to
8265 use it.
8267 2003-09-25 Akim Demaille <akim@epita.fr>
8269 Version 2.57d.
8271 * bin/Makefile.am (edit): Handle '@configure_input@'.
8272 (autoconf, autoheader, autom4te, autoreconf, autoscan, autoupdate)
8273 (ifnames): chmod -w.
8274 * tests/wrapper.as (AUTOCONF, AUTOM4TE, ): Point to tests/
8275 executables, not bin/ executables! Otherwise all the magic needed
8276 to find non installed files is turned off. This caused a failure
8277 of test 40 and 41 that ran aclocal 1.8 which in turn ran autom4te
8278 as found in its environment (sent by tests/autoreconf): pointing
8279 to bin/autom4te that could not find its files.
8280 * tests/mktests.sh: Force the replacement of generated files, for
8281 the sake of "mv" program that are interactive when overwriting a
8282 -w file.
8283 * config/install-sh: Upgrade from CVS Automake.
8285 2003-09-23 Paul Eggert <eggert@twinsun.com>
8287 * doc/autoconf.texi (Limitations of Builtins): Document test -h
8288 versus test -L issues.
8290 2003-09-23 Daniel Jacobowitz <drow@mvista.com> and
8291 Paul Eggert <eggert@twinsun.com>
8293 Trivial change to support GCC's configuration procedure.
8294 * lib/autoconf/c.m4 (AC_PROG_CPP_WERROR): New macro.
8295 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): Don't warn
8296 about inconsistency if the preprocessor is set to give errors for
8297 any warning.
8298 * doc/autoconf.texi (C Compiler Characteristics): Document this.
8300 2003-09-13 Alexandre Duret-Lutz <adl@gnu.org>
8302 * Makefile.am (autom4te-update, autom4te_files): Fetch Struct.pm
8303 and XFile.pm from Automake.
8304 * lib/Autom4te/XFile.pm: Update from Automake.
8306 2003-09-12 Akim Demaille <akim@epita.fr>
8308 Version 2.57c.
8310 2003-09-12 Akim Demaille <akim@epita.fr>
8312 * config/config.guess, config/config.sub, config/missing,
8313 * lib/Autom4te/Channels.pm, lib/Autom4te/Configure_ac.pm: Update
8314 from masters.
8316 2003-09-12 Akim Demaille <akim@epita.fr>
8318 * doc/autoconf.texi (Header Portability): Promote linux/types.h,
8319 not asm/types.h.
8321 2003-09-11 Akim Demaille <akim@epita.fr>
8323 * doc/autoconf.texi (Header Portability): linux/random.h.
8324 From Peter Hendrickson.
8326 2003-09-10 Akim Demaille <akim@epita.fr>
8328 * tests/mktests.sh (au_exclude_egrep): Make it harder to be
8329 willing to edit the output files.
8331 2003-09-10 Akim Demaille <akim@epita.fr>
8333 * tests/fortran.at (GNU Fortran 77): Also exercise AC_FC_SRCEXT
8334 and AC_FC_FREEFORM.
8335 * tests/mktests.sh: Skip AC_FC_SRCEXT.
8336 * lib/autoconf/fortran.m4 (AC_FC_SRCEXT, AC_FC_FREEFORM): Likewise.
8338 2003-09-09 Akim Demaille <akim@epita.fr>
8340 * lib/Autom4te/FileUtils.pm (&update_file): s/cannot not/cannot/g.
8341 Reported by Gary Vaughan.
8342 * bin/autom4te.in (handle_m4): Likewise.
8344 2003-09-09 Akim Demaille <akim@epita.fr>
8346 * lib/Autom4te/FileUtils.pm (&update_file): Be sure not to leave
8347 trailing files.
8349 2003-09-07 Paul Eggert <eggert@twinsun.com>
8351 * lib/autoconf/specific.m4 (AC_SYS_RESTARTABLE_SYSCALLS):
8352 Improve the accuracy of the wording about obsolescence.
8353 From a suggestion by Ian Lance Taylor in
8354 <http://mail.gnu.org/archive/html/autoconf/2003-09/msg00044.html>.
8356 2003-09-05 Paul Eggert <eggert@twinsun.com>
8358 * lib/autoconf/fortran.m4 (AC_FC_FREEFORM): Try -ffree-form too,
8359 for the benefit of g77 3.2. Fix suggested by Steven G. Johnson.
8361 2003-09-04 Akim Demaille <akim@epita.fr>
8363 * tests/mktests.sh (ac_exclude_list): Fix the filtering of
8364 AC_FUNC_WAIT3.
8366 2003-09-04 Akim Demaille <akim@epita.fr>
8368 * bin/autom4te.in: Use &fatal where more appropriate than &error.
8369 (freeze): When exiting, use $exit_code.
8370 * lib/autoconf/fortran.m4: Comment changes.
8372 2003-09-04 Akim Demaille <akim@epita.fr>
8374 * tests/mktests.sh (ac_exclude_list): Add AC_FC_FUNC.
8376 2003-09-02 Steven G. Johnson <stevenj@alum.mit.edu>
8378 Add support for newer Fortran dialects. The F77 interface is
8379 unchanged, and continues to support Fortran 77. New FC macros
8380 correspond to all the old F77 macros, with output variables FC,
8381 FCFLAGS, and FCLIBS. AC_PROG_FC defaults to picking the newest
8382 available dialect, but older dialects can be specified. There are
8383 new macros AC_FC_SRCEXT to set the source extension, and
8384 AC_FC_FREEFORM to accept free-form source files.
8386 * lib/autoconf/c.m4 (_AC_LANG_PREFIX(C), _AC_LANG_PREFIX(C++)):
8387 New macros.
8388 (AC_LANG_PROGRAM(C)): Invoke _AC_LANG_PROGRAM_C_FC_HOOKS if defined.
8389 * lib/autoconf/fortran.m4 (AC_LANG(Fortran), _AC_FORTRAN_ASSERT,

8403 AC_F77_DUMMY_MAIN, AC_F77_MAIN, _AC_F77_NAME_MANGLING,
8404 AC_F77_NAME_MANGLING, AC_F77_WRAPPERS, AC_F77_FUNC):
8405 Rewrite in terms of the above.
8406 (_AC_PROG_F77_G, _AC_PROG_F77_V_OUTPUT, _AC_PROG_F77_V): Remove.
8407 * lib/autoconf/lang.m4 (_AC_LANG_PREFIX): New macro.
8408 * tests/acfortran.at: Test AC_FC_FREEFORM, AC_FC_FUNC,
8409 AC_FC_MAIN, AC_FC_SRCEXT, AC_FC_WRAPPERS, AC_PROG_FC_C_O.
8411 2003-09-02 Paul Eggert <eggert@twinsun.com>
8413 * doc/autoconf.texi (Limitations of Usual Tools, Limitations of Make):
8414 Document problems with timestamp resolution that 'make', 'cp -p', and
8415 'touch -r' have.
8417 2003-08-27 Akim Demaille <akim@epita.fr>
8419 * tests/m4sugar.at (cross_warning): Make sure to enable the
8420 output, so that we can track spurious m4sugar output.
8421 * tests/local.at: Require 2.57.
8422 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): Don't m4_default the arguments that
8423 are defaulted by AT_CHECK anyway.
8424 Use AT_CHECK_AUTOM4TE.
8425 * lib/m4sugar/m4sugar.m4: There should be no output at all: add a
8426 missing dnl.
8428 2003-08-27 Akim Demaille <akim@epita.fr>
8430 * bin/autoheader.in: Issue the "Using auxiliary..." message only
8431 when -Wobsolete is set.
8432 Set it on by default.
8433 Suggested by Klee Dienes.
8435 2003-08-27 Akim Demaille <akim@epita.fr>

8484 * bin/autom4te.in: Adjust to output the call stack.
8485 * tests/m4sugar.at (m4@&t@_warn): Adjust.
8487 2003-08-22 Akim Demaille <akim@epita.fr>

8510 2003-08-21 Akim Demaille <akim@epita.fr>
8512 First stab at preserving warnings between calls to autom4te,
8513 including when the cache is used.
8515 There are still several issues: (i) there are too many runs of m4
8516 (one for include, one for warnings, and some more), (ii) warnings
8517 spreading on several lines are not handled gracefully, (iii) the
8518 code meant to have the call stack display for errors does not work
8519 (its handling should move from m4 to autom4te).
8521 * bin/autom4te.in Autom4te::Channels, Autom4te::ChannelDefs):
8522 Use them.
8523 (@preselect): Add m4_warn.
8524 ($exit_status): Remove, use $exit_code.
8525 ($help): Use Autom4te::ChannelDefs::usage.
8526 (&handle_m4): No longer define the m4_warnings.
8527 At each run, extract and report the warnings.
8528 Always cache the result, including if the exit status is on
8529 failure, since if nothing changes, we should result in the same
8530 failure, hence we can use the cache.
8531 * lib/m4sugar/m4sugar.m4 (m4_warning_ifelse, _m4_warning_ifelse)
8532 (_m4_warning_error_ifelse, __m4_warning_error_ifelse, _m4_warn):
8533 Remove.
8534 (m4_warn): Redefine as a do-nothing: it is its invocation that
8535 matters, as warnings are now reported via traces.
8536 * lib/autoconf/general.m4 (AC_DIAGNOSE): Don't make it a copy of
8537 the contents of m4_warn: make it _call_ m4_warn, so that tracing
8538 the latter reveals calls to the former.
8540 Adjust the tests.
8542 * tests/m4sugar.at (m4@&t@_warn): Use existing warning categories.
8544 2003-08-21 Akim Demaille <akim@epita.fr>
8546 * bin/autoreconf.pm (Autom4te::Channels, Autom4te::ChannelDefs):
8547 Use them.
8549 2003-08-21 Akim Demaille <akim@epita.fr>
8551 * lib/Autom4te/FileUtils.pm (&find_file): Walk the @include in
8552 forward order.
8553 * lib/Autom4te/ChannelDefs.pm: Doc typos.
8554 (&parse_warnings): Accept a list of warning requests.
8555 (&usage): Return a string, not a side effect.
8556 (cross): New warning category.
8558 2003-08-21 Akim Demaille <akim@epita.fr>
8560 * lib/Autom4te/Configure_ac.pm (&find_configure_ac)
8561 (&require_configure_ac): Accept an optional directory argument.
8562 ($configure_ac): Remove.
8563 * lib/Autom4te/General.pm (&find_configure_ac, &canonfile)
8564 (&catfile): Remove.
8565 * bin/autoheader.in, bin/autoreconf.in, bin/autoupdate.in,
8566 * bin/autoscan.in: Adjust.
8568 2003-08-20 Akim Demaille <akim@epita.fr>
8570 * bin/autoheader.in: Remove duplicate 'use Autom4te::FileUtils'.
8571 Reported by Alexandre Duret-Lutz.
8573 2003-08-20 Akim Demaille <akim@epita.fr>
8575 * bin/autoupdate.in, bin/autoheader.in, bin/autoreconf.in,
8576 * bin/autom4te: Adjust.
8577 In particular, be Autoconf tools are really silent when properly
8578 working, bind the verbosity of the 'note' channel to $verbose.
8579 * lib/Autom4te/General.pm (&find_file, &mtime, &update_file)
8580 (&xsystem, &contents): Remove, since they are exported by...
8581 * lib/Autom4te/FileUtils.pm: this.
8582 More perldoc.
8583 * lib/Autom4te/General.pm (&up_to_date_p): Move to...
8584 * lib/Autom4te/FileUtils.pm: here.
8586 2003-08-20 Akim Demaille <akim@epita.fr>
8588 * lib/Autom4te/Channels.pm, lib/Autom4te/ChannelDefs.pm
8589 * lib/Autom4te/Configure_ac.pm, lib/Autom4te/FileUtils.pm: New,

8641 * lib/autotestgeneral.m4 (AT_INIT): Reformat test summary line to print
8642 DESCRIPTION rather than FILE and LINE. Shorten result to fit in new,
8643 shorter column three. Add DESCRIPTION to log file content.
8645 2003-08-13 Derek Price <derek@ximbiot.com>
8647 * lib/autotest/general.m4 (AT_INIT): Correct typo in final status
8648 output.

8680 * lib/autoconf/functions.m4 (AC_FUNC_MMAP): Cast pointer to
8681 'long', not 'int', for benefit of Sun's recent C++ compilers
8682 (trivial change). See:
8683 http://mail.gnu.org/archive/html/autoconf-patches/2003-07/msg00007.html
8684 (This really should be 'intptr_t', not 'long', but that would
8685 take more work.)
8687 2003-06-25 Akim Demaille <akim@epita.fr>
8689 * lib/Makefile.am (autom4te.cfg): Make it read only.
8690 Depend on Makefile since it contains substitutions.
8691 From Paolo Bonzini.
8692 * lib/autom4te.in (args): Add local.at? for Autotest args.
8693 This change was made on autom4te.cfg which is generated.
8694 Reported by Raja R. Harinath.
8696 2003-06-25 Akim Demaille <akim@epita.fr>
8698 * doc/autoconf.texi (Header Portability): sys/mount.h.
8699 From Gareth McCaughan.
8701 2003-06-23 Akim Demaille <akim@epita.fr>
8703 * lib/autotest/general.m4 (AT_INIT): Report a single config.log,
8704 not all of them. This fixes 1. the fact that when testing
8705 Autoconf there are many many config.log, 2. the incorrect use of
8706 top_srcdir to find config.log.
8707 Don't mix the detailed output of failed test with the summary of
8708 failures. Rather, append detailed log afterwards.
8710 2003-06-23 Akim Demaille <akim@epita.fr>
8712 * tests/local.at (AT_CHECK_CONFIGURE): Adjust to the verbose being
8713 always run: output config.log on $at_group_log.
8715 2003-06-23 Akim Demaille <akim@epita.fr>
8717 * tests/torture.at (#define header templates): Don't use quotes in
8718 C++ comments as it puzzles Emacs' sh font-lock-mode.
8720 2003-06-23 Akim Demaille <akim@epita.fr>
8722 * tests/mktests.sh (au_exclude_egrep): Fix output copyright notice.
8723 * lib/autom4te.cfg (args): Add local.at? for Autotest args.
8724 * tests/atspecific.m4: Rename as...
8725 * tests/local.at: This.
8726 * tests/suite.at: Move the globals into...
8727 * tests/local.at: here.
8728 * tests/Makefile.am: Adjust.
8729 * doc/autoconf.texi (testsuite Scripts): Adjust.
8731 2003-06-21 Kevin Ryde <user42@zip.com.au>
8733 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Extend test program to get an
8734 error from OSF 4.0 Compaq cc in its default almost-ANSI mode, thereby
8735 ensuring we add -std1 for full-ANSI.
8737 * doc/autoconf.texi (hdrindex): New macro.
8738 Add index entries for portability of various standard header files.
8740 2003-06-20 Akim Demaille <akim@epita.fr>
8742 * configure.ac: Bump to 2.57b.
8744 2003-06-20 Akim Demaille <akim@epita.fr>
8746 Version 2.57a.
8748 2003-06-20 Akim Demaille <akim@epita.fr>
8750 * bin/autom4te.in: Don't rely on $HOME being defined.
8751 Reported by Marc Espie as PR/233.
8753 2003-06-20 Akim Demaille <akim@epita.fr>
8755 * lib/autotest/general.m4: Use at_times_file only if used.
8756 From Nicolas Joly.
8758 2003-06-20 Akim Demaille <akim@epita.fr>
8760 * config/config.guess, config/config.sub, config/elisp-comp,
8761 * config/install-sh, config/mkinstalldirs, doc/standards.texi:
8762 Update from masters.
8764 2003-06-11 Paolo Bonzini <bonzini@gnu.org>
8766 * doc/autoconf.texi (Writing testsuite.at): Document AT_XFAIL_IF
8767 * lib/autotest/general.m4 (AT_XFAIL_IF): New macro.
8768 (TEST_SCRIPT): New diversion.
8769 (AT_SETUP): Divert output to TEST_SCRIPT and move some code...
8770 (AT_CLEANUP): ...to here. Undivert TEST_SCRIPT.
8771 (AT_INIT): Support for expected failures.
8773 2003-06-02 Akim Demaille <akim@epita.fr>
8775 * bin/autom4te.in, bin/autoscan.in, bin/autoheader.in: White space
8776 changes.
8777 * lib/Autom4te/General.pm (&backname): Remove, no longer used by
8778 Autoconf nor Automake.
8779 (&contents): New, from Automake.
8780 PODify.
8782 2003-05-28 Paul Eggert <eggert@twinsun.com>
8784 * NEWS, doc/autoconf.texi (Particular Functions),
8785 lib/autoconf/functions.m4 (AC_FUNC_MKTIME): Check that mktime
8786 is the inverse of localtime.
8788 2003-05-25 Alexandre Duret-Lutz <adl@gnu.org>
8790 * lib/Autom4te/General.pm (END): Print diagnostics to STDERR.
8791 (handle_exec_errors): New function. Work around $! being
8792 altered by WEXITSTATUS.
8793 (xqx, xsystem): Use handle_exec_errors.
8795 2003-05-23 Alexandre Duret-Lutz <adl@gnu.org>
8797 * lib/Autom4te/General.pm (END): Rewrite exit code processing.
8798 Do not call `_exit()', simply modify `$?'.
8799 (xsystem): Reset $! before running system, and check it afterward.
8800 * tests/tools.at (autoupdating AC_PREREQ): Expect exit status
8801 63 for version mismatches.
8803 2003-05-23 Akim Demaille <akim@epita.fr>
8805 * lib/autoconf/status.m4: Prefer "TAB-SP" to "SP-TAB", because of
8806 Emacs' dangerous whitespace.el behavior (smashing "useless" spaces in
8807 the middle of a line).
8808 * lib/m4sugar/m4sugar.m4: Likewise.
8809 Remove useless spaces in comments.
8811 2003-05-23 Akim Demaille <akim@epita.fr>
8813 * lib/m4sugar/m4sugar.m4 (m4_version_prereq): Failure causes an
8814 exit 63, so that we (or Automake's "missing") can tell the
8815 difference with a plain failure.
8816 * doc/autoconf.texi (Notices): Adjust.
8818 2003-05-23 Akim Demaille <akim@epita.fr>
8820 * Makefile.am, bin/Makefile.am, config/Makefile.am,
8821 * doc/Makefile.am, lib/autoconf/Makefile.am, tests/Makefile.am:
8822 White spaces cleanup.
8824 2003-05-22 Jim Meyering <jim@meyering.net>
8825 Paul Eggert <eggert@twinsun.com>
8827 * lib/autoconf/c.m4 (_AC_PROG_CXX_EXIT_DECLARATION):
8828 Remove `#include <stdlib.h>' from the list; we should never
8829 make confdefs.h include <stdlib.h> or <cstdlib>, because the
8830 resulting namespace pollution would cause other tests to fail.
8831 Configure scripts run with some older versions of g++ and HP's
8832 aCC would fail due to such an #include. Problems reported by
8833 Matthew Mueller in <http://bugs.debian.org/120704> and by
8834 Keith Bostic in
8835 <http://mail.gnu.org/archive/html/autoconf/2003-05/msg00063.html>.
8836 In the test, use the test declaration before including <stdlib.h>,
8837 as that's closer to how it'll be used.
8839 2003-05-23 Akim Demaille <akim@epita.fr>
8841 * doc/autoconf.texi (Header Portability): ucred.h.
8842 From Ian Redfern.
8844 2003-05-22 Paolo Bonzini <bonzini@gnu.org>
8846 Overhaul Autotest's logging: generate separate log files
8847 in testsuite.dir/NNN/testsuite.log, and append them to
8848 testsuite.log instead of re-running the test verbosely.
8850 * lib/autotest/general.m4 (AT_INIT): Use a single redirected
8851 file descriptor, write 0 to at_status_file instead of setting
8852 at_status=0, initialize some new variables (at_status_file,
8853 at_group_log, at_suite_log, at_tee_pipe). Remove the cruft
8854 to rerun the tests, instead append the at_group_log to the
8855 at_suite_log when a test fails.
8856 (AT_SETUP): pipe the test case's output into at_tee_pipe,
8857 with the AS_MESSAGE_LOG_FD redirected to stdout.
8858 (AT_CLEANUP): save the output status in $at_status_file
8859 and restore it, redirect the AS_MESSAGE_LOG_FD back to
8860 its original place.
8861 (AT_CHECK): since tests are run with a redirected stdout,
8862 and used to be re-run in verbose mode, turn some $at_verbose
8863 into echo, and don't redirect the output of testing stdout
8864 and stderr.
8866 * lib/autotest/autoconf.texi (testsuite Scripts): Update
8867 the name of the debugging directory and information about
8868 its contents.
8870 2003-05-22 Paolo Bonzini <bonzini@gnu.org>
8872 * lib/m4sugar/m4sh.m4 (AS_REQUIRE): Actually use the 2nd
8873 parameter.
8875 2003-05-22 Akim Demaille <akim@epita.fr>
8877 * lib/autoconf/autotest.m4, lib/autoconf/autoupdate.m4

8939 2003-05-17 Akim Demaille <akim@epita.fr>
8941 * lib/autoconf/functions.m4: Use the default includes so that
8942 memcmp be declared before being tested.
8943 Reported by Sander Niemeijer.
8944 (AC_FUNC_ERROR_AT_LINE, AC_FUNC_GETGROUPS, AC_FUNC_STRNLEN): Likewise.
8945 * doc/autoconf.texi (Default Includes): Document
8946 AC_INCLUDES_DEFAULT.
8948 2003-05-17 Akim Demaille <akim@epita.fr>
8950 * lib/autoconf/specific.m4: Include signal.h and unistd.h.
8951 * doc/autoconf.texi (Obsolete Macros): Adjust.

8985 and truncate.
8987 2003-05-06 Akim Demaille <akim@epita.fr>
8989 Don't try to be smart with aclocal 1.8+ because (i) aclocal no
8990 longer updates aclocal.m4 if useless, (ii) if a file m4_included
8991 by aclocal.m4 is changed it might require the importing of another
8992 m4 extension file, i.e., aclocal must be run.
8994 * bin/autoreconf.in (&run_aclocal, $aclocal_supports_force): New.
8995 (&parse_args): Use --force with aclocal if required and supported.
8996 (&autoreconf_current_directory): Use &run_aclocal.

9002 * lib/Autom4te/XFile.pm ($me, &name, &lock, &truncate, &seek): New.
9003 * bin/autom4te.in (&Request::save, &Request::load): Use an IO::File
9004 argument instead of a file name, so that the request file remains
9005 open during the whole autom4te run.
9006 ($icache_file): New.
9007 (&freeze): Lock the $icache_file.
9009 2003-04-29 Derek Price <derek@ximbiot.com>
9011 * lib/autotest/general.m4 (AT_KEYWORDS): Don't use a comma as the
9012 seperator with m4_append_uniq(). It doesn't work.
9013 (AT_CLEANUP): Add `;' to end of at_help_all.
9014 (AT_INIT): Allow --keywords to be specified more than once. When
9015 grepping $at_help_all for keywords, use the field and keyword
9016 seperators to ensure a complete keyword match. Alter at_prev handling
9017 to support the new --keywords behavior.
9019 2003-04-27 Karl Berry <karl@freefriends.org>
9021 * doc/autoconf.texi: Make the dir entries in the autoconf manual
9022 align better with others. I also made some of the individual
9023 entries on one line, for brevity and to make it easier for me to
9024 sort my dir-example file in the Texinfo distribution :).
9026 2003-04-12 Jim Meyering <jim@meyering.net>
9028 * NEWS: Mention the new macro.
9029 * lib/autoconf/c.m4 (AC_C_RESTRICT): New macro.

9064 New.
9065 Use them.
9066 * doc/Makefile.am (CLEANFILES): Adjust.
9067 (TEXI2DVI): Make it --batch.
9069 2003-03-31 Derek Price <derek@ximbiot.com>
9071 * lib/autotest/general.m4: Revert the checkin from 2003-03-27
9072 which removed the main loop.
9073 Thanks to Akim Demaille.
9075 2003-03-29 Akim Demaille <akim@epita.fr>
9077 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Skip OS/2's install,
9078 that starts a GUI.
9079 From Ilya Zakharevich.
9081 2003-03-29 Akim Demaille <akim@epita.fr>
9083 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): The
9084 documentation to read is Autoconf's.
9085 Suggested by Paul Eggert.
9087 2003-03-28 Akim Demaille <akim@epita.fr>
9089 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): Suggest
9090 reading the section "Present But Cannot Be Compiled" when the
9091 header causes problems.
9093 2003-03-28 Akim Demaille <akim@epita.fr>
9095 * tests/torture.at (Configuring subdirectories): Require aclocal
9096 1.4, otherwise the test fails, as it does support configure.ac.
9097 This fixes the "test 40 failed" bug reports.
9099 2003-03-28 Akim Demaille <akim@epita.fr>
9101 * doc/autoconf.texi (C Compiler): `#line' portability.
9102 From Paul Eggert and Nelson H. F. Beebe.

9130 sense. Verbosify the diversion definitions comment.
9132 2003-03-26 Derek Price <derek@ximbiot.com>
9134 * lib/autotest/general.m4 (AT_INIT): Remove redundant call to
9135 AS_PREPARE.

9156 file name for the m4 program, when it has an "exe" file extension.

9167 about `$<' in inference rules, it was a bogus interpretation of
9168 an old Automake change. Discuss NetBSD, FreeBSD, OpenBSD, and
9169 Tru64 make in the "target lookup" section.
9170 (Automake): Automake 1.5+ no longer requires special tools to be
9171 present on the developer's host.
9173 2003-02-26 Richard Dawe <rich@phekda.freeserve.co.uk>
9175 * bin/autoheader.in (BEGIN): For DJGPP SHELL may not be set
9176 to a shell that can handle redirection or quoting correctly.
9177 Override SHELL with the shell detected by configure.
9178 Use of $^O suggested by Tim van Holder.
9179 * bin/autom4te.in (BEGIN): Likewise.
9180 * bin/autoreconf.in (BEGIN): Likewise.
9181 * bin/autoscan.in (BEGIN): Likewise.
9182 * bin/autoupdate.in (BEGIN): Likewise.
9183 * bin/ifnames.in (BEGIN): Likewise.
9185 * bin/ifnames.in: Add final newline to help and version messages.
9187 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Translate colons,
9188 to cope with DOS-style absolute paths, when constructing
9189 ${ac_make}.
9191 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS, _AC_OUTPUT_FILES):
9192 When constructing paths with IFS=:, quote the path. If we're
9193 constructing a DOS-style absolute path, we don't want to split it
9194 on the colon.
9196 * tests/atspecific.m4 (AT_CHECK_CONFIGURE): Fix typo
9197 in description.
9199 2003-02-25 Pavel Roskin <proski@gnu.org>

9207 2002-09-01 patch by replacing "test -n" with "test -z".
9208 This fixes a bug found by Jeff Painter and reported by Tom Epperly in
9209 <http://mail.gnu.org/archive/html/autoconf/2003-02/msg00139.html>.
9211 * doc/autoconf.texi (Shell Substitutions): test -n -> test -z,
9212 to fix a mismatch between example and discussion.
9214 2003-02-24 Kevin Ryde <user42@zip.com.au>
9216 * doc/autoconf.texi (Limitations of Builtins): Add notes on printf
9217 format starting with "-".
9219 2003-02-20 Alexandre Duret-Lutz <adl@gnu.org>
9221 * doc/autoconf.texi (Limitations of Make): `foo=bar make -e'
9222 is not portable inside Makefile.
9224 2003-02-20 Akim Demaille <akim@epita.fr>
9226 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): When
9227 compiler says yeah, but preproc says nope, compiler is right.
9228 Conversely, prompt the reader to send a bug report to the
9229 maintainers of the package, not of Autoconf.
9231 2003-02-20 Klee Dienes <kdienes@apple.com>
9233 * bin/autoreconf.in (autoreconf_current_directory): Properly
9234 handle an empty aclocal.m4.

9238 * lib/autoconf/general.m4 (AC_PREFIX_PROGRAM): Quote
9239 $ac_prefix_program.
9240 From Larry Jones.
9242 2002-12-23 Paul Eggert <eggert@twinsun.com>
9244 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Define $1 to an
9245 innocuous variant befor including <limits.h> or <assert.h>. This
9246 works around a bug reported by Albert Chin: HP-UX 11i
9247 (and earlier versions) have a <limits.h> that declares
9248 gettimeofday and many other functions.
9250 2002-12-03 Paul Eggert <eggert@twinsun.com>
9252 Version 2.57.
9254 * NEWS, configure.ac: Update version.
9256 * doc/fdl.texi: Upgrade to FDL version 1.2.
9258 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Use the function f
9259 nontrivially in main's body, so that f's external declaration is
9260 not optimized away in AIX. This should fix the bug reported by
9261 Martin Frydl in
9262 <http://mail.gnu.org/pipermail/autoconf/2002-November/014508.html>.
9264 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C),
9265 _AC_PROG_PREPROC_WORKS_IFELSE): Use <limits.h> if __STDC__ is
9266 defined, to support freestanding compilers. This should fix the
9267 bug reported by Momchil Velkov in
9268 <http://mail.gnu.org/pipermail/autoconf/2002-November/014490.html>.
9270 * doc/autoconf.texi (Obsolete Macros): Fix typos (insert empty
9271 arg, AC_DEFINE -> AC_DEFINE_UNQUOTED) in documentation for

9276 * Makefile.maint (www-gnu): New macro.
9277 (standards.texi-url_prefix, make-stds.texi-url_prefix): Use it, as
9278 the location has moved.
9280 2002-12-02 Martin Frydl <martin@systinet.com>
9282 * bin/autom4te.in (at_flatten): rewritten to avoid M4 problem when
9283 \(.*\) match is too long and there is something more to be checked.
9284 <http://mail.gnu.org/pipermail/autoconf/2002-November/014524.html>
9286 2002-11-15 Akim Demaille <akim@epita.fr>

9292 * config/move-if-change: Indenting changes.
9293 * Makefile.am (AUTOMAKE_OPTIONS): Move to...
9294 * configure.ac (AM_INIT_AUTOMAKE): here.
9295 Require 1.7.1.
9297 2002-11-14 Akim Demaille <akim@epita.fr>
9299 Version 2.55.
9301 * config/config.guess, config/config.sub, config/install-sh:
9302 Update from masters.
9304 2002-11-14 Akim Demaille <akim@epita.fr>
9306 * Makefile.maint: Sync with Bison, i.e.:
9307 (po-check): Scan .l and .y files instead of the
9308 .c and the .h files that they generate. This fixes the bug
9309 reported by Tim Van Holder in:
9310 <http://mail.gnu.org/pipermail/bison-patches/2002-November/001352.html>
9311 Look for N_ as well as for _. Try to avoid matching #define for
9312 N_ and _.
9313 From Paul Eggert.
9315 2002-11-14 Akim Demaille <akim@epita.fr>
9317 * doc/autoconf.texi (C Compiler): Compiling several files at once.
9318 From Paul Eggert and Albert Chin-A-Young.
9320 2002-11-14 Akim Demaille <akim@epita.fr>
9322 * doc/autoconf.texi (C Compiler): Solitary backslashes.
9323 From Paul Eggert and Albert Chin-A-Young.
9325 2002-11-14 Kevin Ryde <user42@zip.com.au>
9327 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Initialize f=$1 rather
9328 than assigning in main, to avoid HP cc +O3 optimizing it away.
9330 2002-11-12 Peter Eisentraut <peter_e@gmx.net>
9332 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Add -q
9333 option. Process --recheck after parsing all options. Pass -q
9334 option to configure on --recheck.
9335 (AC_OUTPUT): Pass -q from configure to config.status.
9336 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Strip -q from
9337 arguments to record.
9338 * doc/autoconf.texi (config.status Invocation): Document
9339 config.status -q option.
9341 2002-11-07 Alexandre Duret-Lutz <adl@gnu.org>
9343 * bin/autoscan.in (scan_file): Scan Makefile.am too. Ignore
9344 Makefile.in if Makefile.am exists.
9345 (output): Strip `.am' from Makefiles. Don't
9346 output AC_CONFIG_FILES if no Makefiles were found.
9348 2002-11-07 Akim Demaille <akim@epita.fr>
9350 * Makefile.am (cvs_files): Add elisp-comp, mdate-sh.

9355 2002-11-06 Akim Demaille <akim@epita.fr>
9357 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY): Wrap the `f'
9358 declaration in extern "C" too.

9363 * tests/torture.at (Configuring subdirectories): Don't use grep
9364 -w.
9365 * doc/autoconf.texi (Limitations of Usual Tools): Grep -w.
9366 Reported by Ezra Peisach.
9368 2002-11-05 Akim Demaille <akim@epita.fr>
9370 * lib/autoconf/autoheader.m4 (_AH_TEMPLATE_OLD, _AH_VERBATIM_OLD):
9371 Remove.
9372 We _have_ to stop using the old compatibility scheme that tried to
9373 avoid useless backslashes because Libtool 1.4.3 contains a
9374 AC_DEFINE([error_t], [int],
9375 [Define to a type to use for \`error_t' if it is not
9376 otherwise available.])
9377 We _have_ to quote the single quote and backslashes with \. The
9378 old compatibility scheme saw that ` was backslashed, and therefore
9379 did not quote the single quote. Hence before this patch, Autoconf
9380 was not compatible with Libtool.
9382 2002-11-04 Paul Eggert <eggert@twinsun.com>
9384 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Set the following variables,

9391 Version 2.54c.
9393 * Makefile.maint (update, cvs-update, po-update, do-po-update):

9399 * bin/autoreconf.in (&autoreconf_current_directory): New, extracted
9400 from...
9401 (&autoreconf): here.
9402 ($help, $make, &parse_args, &autoreconf_current_directory):
9403 Support -m/--make.
9404 * doc/autoconf.texi (autoreconf Invocation): Adjust.

9422 2002-10-31 Akim Demaille <akim@epita.fr>
9424 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Use and display
9425 `$(MAKE)' instead of '${MAKE}' to emphasize that we refer to the
9426 Make variable, not a shell variable.
9427 Suggested by Bruno Haible.
9429 2002-10-31 Akim Demaille <akim@epita.fr>
9431 * bin/autom4te.in (load_configuration): Reject #args out of any
9432 language.
9434 2002-10-31 Akim Demaille <akim@epita.fr>
9436 * lib/autoconf/general.m4 (_AC_MSG_LOG_CONFTEST): New.

9448 Suggested by Tim van Holder.

9452 * doc/autoconf.texi (Particular Functions): AC_FUNC_MALLOC and
9453 AC_FUNC_REALLOC check for compatibility with glibc, not POSIX.
9454 Problem reported by Bruno Haible.
9456 2002-10-29 Akim Demaille <akim@epita.fr>
9458 * doc/autoconf.texi (Header Templates): Put also in words what the
9459 pictures says to assist free style readers.
9460 (Customizing autom4te): s/--cache=/--cache /.
9462 2002-10-29 Akim Demaille <akim@epita.fr>
9464 * lib/autoconf/functions.m4 (_AC_FUNC_VFORK): Include stdlib.h and
9465 sys/wait.h.

9690 `$ac_configure_args'.

9709 * doc/autoconf.texi (Limitations of Usual Tools): Remove incorrect
9710 words about HP-UX cmp: it was actually a user-written cmp.
9712 2002-10-22 Akim Demaille <akim@epita.fr>
9714 * tests/foreign.at (Libtool): Don't check autoconf's stderr: there
9715 are a few warnings.
9716 * lib/autoconf/autoheader.m4 (AH_VERBATIM, _AH_VERBATIM_OLD):
9717 Quote for Perl '' strings, not "".
9718 * bin/autoheader.in: Invoke autoconf to get '' strings, not ""
9719 strings.
9721 2002-10-22 Akim Demaille <akim@epita.fr>
9723 * lib/m4sugar/m4sh.m4 (_AS_QUOTE): The warning about quoted
9724 characters is a syntax warning now.
9725 (_AS_QUOTE): Accept $2 as list of characters to quote.
9726 * lib/autoconf/autoheader.m4 (AH_VERBATIM, _AH_VERBATIM_OLD):
9727 Quote for Perl, not sh.
9728 * bin/autoheader.in: When $debug, report the file which is

9731 `@', to tickle Perl's lists.
9732 Reported by Carlos Velasco.
9734 2002-10-18 Akim Demaille <akim@epita.fr>
9736 * bin/autom4te.in (handle_m4): Pass --fatal-warning to m4, so that
9737 missing included files _are_ errors.
9738 Thanks to Alexandre Duret-Lutz.
9739 * tests/tools.at (autom4te cache): Adjust.

9746 2002-10-17 Akim Demaille <akim@epita.fr>
9748 * lib/autoconf/general.m4 (AC_CACHE_SAVE): Don't use cmp.
9749 Fixes the `AC_ARG_VAR' test failures.
9750 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Don't use cmp.
9751 * lib/freeze.mk (check-forbidden-patterns): New.

9767 2002-10-16 Akim Demaille <akim@epita.fr>
9769 Because of caching, some files that no longer exist and are no
9770 longer required can still cause errors.
9771 Reported by Alexandre Duret-Lutz.
9773 * bin/autom4te.in (&parse_args): Do not prepend `--reload-state'
9774 to frozen files in @ARGV, as @ARGV must remain being a list of
9775 files. Rather, at M4 call sites, use this...
9776 (&files_to_options): New function.
9777 (&freeze): Use &error.
9778 (&up_to_date): If a file that was included according to the cache
9779 is no longer there, then the output is out dated.
9780 (&main): Don't even check whether a file is up to date is anyway
9781 --force is given.
9782 * tests/tools.at (autom4te cache): New.
9784 2002-10-16 Akim Demaille <akim@epita.fr>
9786 * bin/autoconf.as: Kill dead options.
9787 * bin/autoupdate.in (&parse_args): Kill old options.
9788 * bin/autoreconf.in (&parse_args): Remove dead options.
9789 Factor some code.
9790 (&autoreconf): Report the directories we enter *and leave*, so
9791 that error messages can be easily located, and use GNU Make
9792 format, so that Emacs' compile mode understands us.
9793 * lib/Autom4te/General.pm (&update_file): Use `verbose' to report
9794 if some file was changed instead of `print'.
9795 * bin/autoheader.in: Suggest AC_DEFINE with 3 args when needed.
9796 (&parse_args): Remove the dead options.
9797 * tests/atspecific.m4 (AT_CHECK_AUTOHEADER): Adjust to the new
9798 autoheader's quiet mode.

9803 2002-10-11 Akim Demaille <akim@epita.fr>

9806 check for compilability.
9808 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL)
9809 (AC_CHECK_HEADER, _AC_CHECK_HEADER_OLD): Remove.

9813 * lib/autotest/general.m4 (AT_INIT): Include the failed test
9814 numbers in the Subject suggestion.

9828 * lib/m4sugar/m4sh.m4 (_AS_PATH_SEPARATOR_PREPARE): Use $$ in the
9829 file name to enable parallel executions.
9830 From Sam Varshavchik.
9832 2002-10-08 Akim Demaille <akim@epita.fr>
9834 * bin/autoreconf.in (&autoreconf): Run autopoint before the first
9835 aclocal invocation, as Gettext macros might not be visible to
9836 aclocal.
9837 Instead of blindly running autopoint, scan configure.ac (not the
9838 traces) for AM_GNU_GETTEXT_VERSION uses, as autopoint does.
9839 Reported by Paul D. Smith.
9841 2002-10-08 Paul Eggert <eggert@twinsun.com>
9843 Work around problems found when POSIXLY_CORRECT=1 is set.
9844 None of this seems to have anything to do with POSIX, really,
9845 but it's how Perl getopt works.
9846 * bin/autom4te.in (parse_args): Configure GetOpt with
9847 "permute", too.
9848 * doc/autoconf.texi (Invoking autom4te):
9849 --warning -> --warnings.
9850 * lib/autom4te.in: --warning -> --warnings.

9869 2002-09-28 Akim Demaille <akim@epita.fr>
9871 * tests/torture.at (Configuring subdirectories): Be robust to
9872 users who use config.site to require for a cache: in this case,
9873 the two last configure runs, using two different sets of
9874 arguments, trigger a legitimate error.
9876 2002-09-28 Akim Demaille <akim@epita.fr>
9878 * tests/m4sh.at (Functions Support, Functions and return Support):
9879 New.

9892 (tm_zone): Move their rules to...
9893 * lib/autoconf/types.m4: here, using AN_ macros.
9894 * lib/autoscan/autoscan.pre (AWK, BISON, INSTALL, LEX, LN, MAKE)
9895 (RANLIB, YACC, awk, bison, byacc, flex, gawk, install, lex, ln)
9896 (make, mawk, nawk, ranlib, yacc): Similarly, move to...
9897 * lib/autoconf/programs.m4: here.
9898 * lib/freeze.mk (ETAGS_FOR_M4, ETAGS_FOR_M4SUGAR)
9899 (ETAGS_FOR_AUTOCONF): New.
9900 Use it.
9902 2002-09-28 Akim Demaille <akim@epita.fr>

9909 * lib/freeze.mk (autoconf_m4f_dependencies): Add autoscan.m4.
9910 (.m4.m4f): Don't pass --prepend-include, since that's done by
9911 tests/autom4te itself.
9912 * lib/autoscan/Makefile.am: Include freeze.mk.
9913 (autoscan.list): New target --this file is no longer a source.
9914 (autoscan.pre): New file.

9918 * bin/autoscan.in (@kinds): Make them singular.
9919 Adjust all uses.
9920 (&init_tables): When --debug, report the list of rules to ease
9921 tracking changes in autoscan.list.
9922 * lib/autoscan/autoscan.list (function): Strip comments, sort.
9924 2002-09-28 Akim Demaille <akim@epita.fr>
9926 * lib/autoscan/functions, lib/autoscan/headers,
9927 * lib/autoscan/identifiers, lib/autoscan/makevars,

9930 * bin/autoscan.in (&init_tables): Adjust.
9932 2002-09-28 Akim Demaille <akim@epita.fr>

9935 * lib/autoscan/identifiers, lib/autoscan/makevars,
9936 * lib/autoscan/programs: Make the `kind' explicit, i.e., each
9937 `functions' line is now prefixed with `function:'.
9938 * bin/autoscan.in (&init_tables): Adjust.
9940 2002-09-28 Akim Demaille <akim@epita.fr>
9942 From now on, autoscan files must always map a macro name to a
9943 word: there is no `default' macro for autoscan.
9945 * bin/autoscan.in (&init_tables): Reject entries with no macro at
9946 all.
9947 * lib/autoscan/functions, lib/autoscan/headers: Make the macro
9948 explicit.
9950 2002-09-28 Akim Demaille <akim@epita.fr>
9952 * bin/autoscan.in (%c_keywords): Remove.
9953 (&used): Keep only track of the words we might be interested in.
9954 (&output_kind): It is no longer needed to look for non active
9955 checks.

9984 * bin/autoreconf.in: Clarify that -s is meaningless without -i.
9985 Reported by Ralf Corsepius.
9986 * doc/autoconf.texi (autoreconf Invocation): Likewise.
9988 2002-09-26 Akim Demaille <akim@epita.fr>
9990 Single suffix rules and seperated dependencies are not portable.
9992 * doc/autoconf.texi (Installation Directory Variables): Update.
9993 (Limitations of Make): Some about `Single Suffix Rules and

9998 2002-09-25 Paul Eggert <eggert@twinsun.com>

10003 2002-09-24 Paul Eggert <eggert@twinsun.com>

10008 * bin/Makefile.am (SUFFIXES, .in): Remove.
10009 (autoconf autoheader autoreconf autoupdate ifnames autoscan autom4te):

10036 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Suggest
10037 reading config.log when the compiler is rejected.
10038 Suggested by Guido Draheim.
10040 2002-09-13 Akim Demaille <akim@epita.fr>
10042 * bin/autoreconf.in: Don't use Cwd::chdir, since in its internals
10043 (chdir_init) might hang when stat'ing mounted directories.
10044 Reported by Vance Shipley.
10046 2002-09-12 Akim Demaille <akim@epita.fr>
10048 * bin/autoscan.in (&parse_args): Pass a reference to the lists, not
10049 the lists.
10051 2002-09-12 Akim Demaille <akim@epita.fr>
10053 * doc/autoconf.texi (Defining Symbols): Present two different
10054 prototypes for AC_DEFINE and AC_DEFINE_UNQUOTED to emphasize the

10059 * doc/autoconf.texi: Review grammar and punctuation.

10064 grammatical typos.
10065 (Defining Symbols): Explain that AC_DEFINE(var) defaults to 1, but
10066 AC_DEFINE(var,,description) does not; and the AC_DEFINE(var) case
10067 is obsolescent.
10069 2002-09-11 Akim Demaille <akim@epita.fr>
10071 * doc/autoconf.texi (Questions): Rename as...
10072 (FAQ): this.

10085 2002-09-09 Akim Demaille <akim@epita.fr>
10087 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Keep the
10088 `duplicates', since the algorithm was too naive and could keep
10089 `--prefix=1 --prefix=2 --prefix=1' as `--prefix=1 --prefix=2', and
10090 keep `--prefix foo --prefix bar' as `--prefix foo bar'.
10091 Reported by Ralf Corsepius.
10092 * tests/torture.at (Configuring subdirectories): Exercise these
10093 cases.
10095 2002-09-09 Akim Demaille <akim@epita.fr>
10097 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Use $srcdir when
10098 looking for a replacement file.

10100 directory is relative.
10101 * doc/autoconf.texi (Generic Functions): Clarify the replacement
10102 directory definition.

10109 Suggested by Pontus Skoeld.
10111 2002-09-05 Akim Demaille <akim@epita.fr>
10113 * bin/Makefile.am (autoconf, autoheader, autoreconf, autoupdate)
10114 (ifnames, autoscan, autom4te): Since we don't only depend on
10115 configure.ac variables (such as VERSION etc.), but also on prefix
10116 and so forth, depend on Makefile, not configure.ac.
10117 Reported by Alexandre Duret-Lutz.
10118 * doc/autoconf.texi (Installation Directory Variables): Adjust.
10120 2002-09-05 Kevin Ryde <user42@zip.com.au>
10122 * doc/autoconf.texi (Limitations of Make): HP-UX trailing backslashes
10123 doesn't seem to be confined to ia64, just say "some versions".
10125 2002-09-04 Akim Demaille <akim@epita.fr>
10127 * Makefile.am, doc/Makefile.am: Remove pdf targets, handled by

10136 Brinkmann.
10138 2002-09-03 Akim Demaille <akim@epita.fr>
10140 * configure.ac: Bump to 2.53d.
10141 * Makefile.am (AUTOMAKE_OPTIONS): Require 1.6c, i.e., CVS Automake
10142 as of today, on Automake's team suggestion.
10144 2002-09-03 Akim Demaille <akim@epita.fr>
10146 Version 2.53c.
10148 2002-09-02 Akim Demaille <akim@epita.fr>

10151 SITE_MACRO_DIR.
10152 * configure.ac: Disable SITE_MACRO_DIR.
10154 2002-09-02 Jim Meyering <meyering@lucent.com>
10156 * doc/autoconf.texi (AC_SYS_POSIX_TERMIOS): Reflect renaming: s/am/ac/,
10157 i.e., change am_cv_sys_posix_termios to ac_cv_sys_posix_termios.
10158 Also, tweak grammar: s/make sure to/be sure to/.
10160 2002-09-02 Paul Eggert <eggert@twinsun.com>
10162 * doc/autoconf.texi (Limitations of Builtins): Explain why logical
10163 directory names are generally preferable to physical names.
10165 2002-09-02 Akim Demaille <akim@epita.fr>
10167 * lib/Autom4te/General.pm (&update_file): s/die/error/.
10168 Reported by Raja R. Harinath.
10169 * bin/autoheader.in, bin/autoreconf.in, bin/autoscan.in,
10170 * bin/autoupdate.in: Use error instead of die.
10172 2002-09-01 Paul Eggert <eggert@twinsun.com>
10174 * tests/mktests.sh (ac_exclude_egrep, au_exclude_egrep): Use
10175 ordinary shell concatenation rather than echo+tr+sed command that
10176 runs afoul of a long-line-related sed bug in Solaris 8.
10178 * bin/autoheader.in (parse_args): --warning -> --warnings.
10180 * bin/autoconf.as: Work even if "ls" outputs "FOO not found" to
10181 stdout, as traditional "ls" does.
10182 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT,
10183 _AC_COMPILER_EXEEXT_O): Likewise.
10184 * doc/autoconf.texi (Limitations of Usual Tools): Add "ls".
10186 * bin/autoconf.as: Add --prepend-include option. This patch was
10187 applied to bin/autoconf.in in the 2002-07-17 patch by Mark D. Roth,
10188 but bin/autoconf.in is generated automatically from bin/autoconf.as.
10190 * bin/autoconf.in, configure: Regenerate.
10192 * doc/autoconf.texi (Special Shell Variables): Mention
10193 ENV, MAIL, MAILPATH, PS1, PS2, PS4. Index PWD.
10195 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Unset ENV, MAIL,
10196 MAILPATH and set PS1, PS2, PS4 to default values, to work
10197 around bug in pre-3.0 UWIN ksh reported by Bruce Lilly.
10198 For LC_ALL etc, first try to set to "C" as POSIX requires and as
10199 the Autoconf documentation specifies; fall back to "unset" only if
10200 this fails. Use a shell for-loop for this rather than an m4 loop,
10201 to shorten the output script.
10203 2002-08-30 Paul Eggert <eggert@twinsun.com>
10205 * doc/autoconf.texi (Special Shell Variables): Mention POSIX
10206 1003.1-2001's requirements for CDPATH. Give a simpler workaround
10207 for the CDPATH problem. Document PWD.
10208 (Limitations of Builtins): Document the problem that "cd $foo" and
10209 "ls $foo" may refer to different directories in shells conforming
10210 to POSIX 1003.1-2001. Use PS1 rather than CDPATH for "unset"
10211 example, since the old example is now out of date.
10213 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Reject FOO if "cd
10214 FOO" and "ls FOO" talk about different directories; this catches
10215 problems when POSIX 1003.1-2001 "cd" fails due to symlink
10216 spaghetti.
10218 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Use AS_UNSET instead
10219 of rolling our own unset.
10220 (_AS_PREPARE): $as_unset CDPATH instead of AS_UNSETting it, since
10221 in practice we needn't worry about CDPATH if unset doesn't work.
10223 * Makefile.in, aclocal.m4, bin/Makefile.in,
10224 config/Makefile.in, doc/Makefile.in, lib/Makefile.in,
10225 lib/Autom4te/Makefile.in, lib/autoconf/Makefile.in,
10226 lib/autoscan/Makefile.in, lib/autotest/Makefile.in,
10227 lib/emacs/Makefile.in, lib/m4sugar/Makefile.in, man/Makefile.in,
10228 tests/Makefile.in: Regenerate with Automake 1.6.3.
10230 * config/config.guess, config/config.sub, config/mkinstalldirs:
10231 Update.
10233 * configure: Regenerate with self.
10235 2002-08-30 Kevin Ryde <user42@zip.com.au>
10237 * doc/autoconf.texi (Limitations of Usual Tools): Notes on "cc"
10238 default output.
10240 2002-08-29 Rainer Orth <ro@TechFak.Uni-Bielefeld.DE>
10242 * bin/autom4te.in (Request::load): Correctly test for "do" read
10243 failure.
10245 2002-08-29 Akim Demaille <akim@epita.fr>
10247 * lib/Autom4te/General.pm (&xqx): New.
10248 (&xsystem): Use WIFEXITED and WEXITSTATUS instead of decoding $? by
10249 hand, which is not portable.
10250 (&error): New.
10251 * bin/autom4te.in: Use them.
10252 Use &error instead of die.
10253 * tests/m4sugar.at (m4_warn, m4_require: circular dependencies):
10254 Adjust.
10256 2002-08-17 Paul Eggert <eggert@twinsun.com>
10258 * lib/autoconf/fortran.m4 (AC_PROG_F77): Remove fc from the
10259 default list of compilers to try, since it was long ago superseded
10260 by the ksh fc builtin. Suggested by Steven G. Johnson.
10262 2002-07-31 Alexandre Duret-Lutz <duret_g@epita.fr>
10264 * doc/autoconf.texi (Invoking autom4te): End the option table,
10265 fixing a bug introduced by the previous patch.
10266 (Limitations of Make): Add a 'target lookup' subentry in the
10267 'VPATH' entry. Rewrite all `make' occurences as `@command{make}'.
10269 2002-07-29 Mark D. Roth <roth@feep.net>
10271 * bin/autom4te.in: Remove --include-envvar and --site-macro-subdir
10272 options and use $AUTOM4TE_PATH.
10273 * doc/autoconf.texi: Remove documentation of autom4te
10274 --include-envvar and --site-macro-subdir options and document
10275 use of $AUTOM4TE_PATH.
10276 * lib/autom4te.in: Remove --include-envvar and --site-macro-subdir
10277 arguments from each language section.
10279 2002-07-29 Paul Eggert <eggert@twinsun.com>
10281 * doc/install.texi: Include copyright symbol in copyright notice.
10283 * Makefile.am (MAKEINFO): Remove; it's a user-specified macro.
10284 Replace with:
10285 (AM_MAKEINFOFLAGS): New macro.
10286 * doc/Makefile.am (MAKEINFO, AM_MAKEINFOFLAGS): Likewise.
10287 * Makefile.am (INSTALL): Use the new macros.
10288 Use -o rather than --output, since "missing" does not grok --output.
10290 2002-07-25 Alexandre Duret-Lutz <duret_g@epita.fr>
10292 * doc/autoconf.texi (Limitations of Make): Escaped newlines in
10293 comments do not always work. Never trust the exit status of
10294 `make -k'.
10296 2002-07-24 Kevin Ryde <user42@zip.com.au>
10298 * doc/autoconf.texi (Limitations of Make, Making testsuite Scripts):
10299 Untabify, since tabs are not enjoyed by texi2dvi and makeinfo.
10301 2002-07-23 Paul Eggert <eggert@twinsun.com>
10303 * lib/m4sugar/m4sh.m4 (_AS_PATH_SEPARATOR_PREPARE):
10304 Use PATH="/nonexistent;.", not PATH=".;.", as FreeBSD ksh2002
10305 apparently treats PATH="nonexistent" as if it contained ".".
10306 Bug reported by Stefan `Sec' Zehl.
10308 2002-07-22 Alexandre Duret-Lutz <duret_g@epita.fr>
10310 * doc/autoconf.texi (Limitations of Make): Mention the special

10327 2002-07-18 Akim Demaille <akim@epita.fr>
10329 Version 2.53b.
10331 2002-07-18 Akim Demaille <akim@epita.fr>
10333 * config/config.guess, config/config.sub: Update.

10437 * tests/semantics.at (AC_C_BIGENDIAN): Likewise.
10439 * tests/mktests.sh: Use grep instead of fgrep, as per
10440 "Limitations of Builtins".

10465 * doc/autoconf.texi: Add more dir entries.
10467 2002-06-10 Alexandre Duret-Lutz <duret_g@epita.fr>
10469 * bin/autom4te.in ($cache): Don't define using `$me', the name
10470 of the cache should not depend on the name under which autom4te
10471 was installed.
10473 2002-06-07 Akim Demaille <akim@epita.fr>
10475 * tests/tools.at (autoconf: forbidden tokens, basic)

10568 Kate Hedstrom.
10569 * NEWS: Document the above.

10572 2002-05-17 Paul Eggert <eggert@twinsun.com>
10574 * lib/autoconf/types.m4 (AC_CHECK_MEMBER): Work correctly even if
10575 the member is itself an aggregate. Bug reported by Sergey Poznyakoff.
10576 This improves on an earlier suggestion by H. Peter Anvin.
10578 2002-05-16 Paul Eggert <eggert@twinsun.com>
10580 AC_FUNC_FNMATCH now tests only for POSIX compatibility.
10581 AC_FUNC_FNMATCH_GNU also tests for GNU extensions.
10582 Both macros now accept an optional source-dir arg.
10583 New macro AC_GNU_SOURCE to define _GNU_SOURCE.
10585 * NEWS: Document this.
10586 * doc/autoconf.texi (Particular Functions, UNIX Variants): Likewise.
10588 * lib/autoconf/functions.m4 (_AC_FUNC_FNMATCH): New macro.
10589 (AC_FUNC_FNMATCH): Use it. Test only for POSIX conformance,

10602 Bug reported by Stephen Gildea.
10604 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
10605 If prototypes are supported, use them to check this at compile-time,
10606 instead of trying to check it at run-time. If we must do a run-time
10607 check, assume that setvbuf is standard when cross-compiling, as
10608 nonstandard setvbuf occurs only on ancient and unlikely hosts.
10609 Bug reported by Paul D. Smith.
10611 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Add optional
10612 argument specifying location of getloadavg.c. This removes a
10613 FIXME. This idea was taken from Jim Meyering's implementation in
10614 textutils.
10615 * doc/autoconf.texi (Particular Functions): Document this.
10616 Also, mention HAVE_NLIST_H rather than NLIST_STRUCT, since
10617 that's what the code does; this fixes a bug reported by
10618 Paul D. Smith.
10620 2002-05-03 Akim Demaille <akim@epita.fr>
10622 * bin/autoreconf.in (autoreconf): Rewrite to use Gettext's
10623 autopoint instead of gettextize.
10624 ($uses_alocal): Rename as...
10625 ($uses_aclocal): this.
10626 * doc/autoconf.texi (autoreconf Invocation): Adjust.
10627 Suggested by Bruno Haible.
10629 2002-05-03 Akim Demaille <akim@epita.fr>
10631 * lib/m4sugar/m4sugar.m4 (m4_map_sep): New.
10633 2002-04-29 Paul Eggert <eggert@twinsun.com>
10635 * bin/autoreconf.in (autoreconf): Don't age aclocal.m4's input
10636 files to be 1 second older; just set them to be the same time.
10637 Also, sleep 1 second after the first aclocal, to work around
10638 problems with sub-second time stamps on the input files.
10640 2002-04-29 Thien-Thi Nguyen <ttn@gnu.org>
10642 * doc/autoconf.texi: Mention "set -e -x" lossage
10643 under node "Limitations of Builtins".
10645 2002-04-29 Akim Demaille <akim@epita.fr>
10647 * doc/install.texi: Better wording for setting variables when
10648 running configure.
10649 From Christian Cornelssen.
10651 2002-04-29 Akim Demaille <akim@epita.fr>
10653 * tests/m4sh.at (LINENO): If testsuite itself is rewritten because
10654 of lack of $LINENO support, then the test will compare the $LINENO
10655 in testsuite vs. the lineno in the test file. This is wrong, of
10656 course.
10657 Be sure to protect it.
10658 Reported by Patrick Welche.
10660 2002-04-25 Akim Demaille <akim@epita.fr>
10662 * doc/autoconf.texi (Obsolete Macros): Typo.
10663 Reported by Vladimir Volovich.
10665 2002-04-25 Akim Demaille <akim@epita.fr>
10667 * bin/autoreconf.in (autoreconf): Don't let aclocal.m4 be older
10668 than some of the input files, hence, on the second run of aclocal,
10669 if some of its input are younger, make them older.
10670 Suggested by Paul Eggert.
10672 2002-04-25 Akim Demaille <akim@epita.fr>
10674 * doc/autoconf.texi (Limitations of Usual Tools): sed and `!'.
10675 Thanks to Paul Eggert.
10677 2002-04-25 Akim Demaille <akim@epita.fr>
10679 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Let ac_subst_files
10680 and ac_subst_vars be sh variables containing the list of
10681 AC_SUBST_FILES'ed and AC_SUBST'ed identifiers. Output them in the
10682 DEFAULT diversion.
10683 (_AC_INIT_PREPARE): Use them to log them.
10684 (_AC_SUBST, _AC_SUBST_SED_PROGRAM): Remove.
10685 (AC_SUBST, AC_SUBST_FILE): Instead of buliding the
10686 _AC_SUBST_SED_PROGRAM, store the list of output files/variables in
10687 _AC_SUBST_FILES and _AC_SUBST_VARS.
10688 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Adjust.
10690 2002-04-24 Akim Demaille <akim@epita.fr>
10692 * bin/autoreconf.in (autoreconf): Run automake after autoconf and
10693 autoheader, so that automake does not complain about a missing
10694 config.h.in that was to be created.
10696 2002-04-23 Akim Demaille <akim@epita.fr>
10698 * bin/autoheader.in (parse_args): --warning takes an argument.
10699 Fixes PR/220.
10701 2002-04-22 Peter Eisentraut <peter_e@gmx.net>
10703 * lib/autoconf/general.m4 (_AC_RUN_IFELSE): Remove gmon.out
10704 and bb.out when cleaning up.
10706 2002-04-22 Akim Demaille <akim@epita.fr>
10708 Version 2.53a.

10714 2002-04-22 Akim Demaille <akim@epita.fr>
10716 * doc/autoconf.texi (Pretty Help Strings): Remove a spurious
10717 comma.
10718 Reported by Gregory Giannoni.
10720 2002-04-22 Akim Demaille <akim@epita.fr>
10722 * tests/m4sh.at (LINENO): Skip the test if LINENO cannot be unset.
10723 Fixes false failures on Darwin.

10748 Minor spelling and grammar fixes.
10750 * doc/autoconf.texi: Follow the outline suggested in the GNU
10751 Sample Texts sections of the Texinfo 4.2 manual. Most
10752 importantly, this makes sure that the copyright notices appear in
10753 all output formats. You probably need Texinfo 4.2 to generate
10754 the manual now.
10756 Fix some bugs when using "$@" when there might be zero positional
10757 arguments in cases where this matters.

10775 * tests/atgeneral.m4 (AT_INIT): Likewise.
10777 * tests/c.at: We can't have zero arguments, so remove workaround
10778 that is not portable to Zsh.
10780 2002-04-19 Alexandre Duret-Lutz <duret_g@epita.fr>
10782 * bin/autoupdate.in (handle_autoconf_macros): Honor AU_DEFUNs
10783 from aclocal.m4 too.
10785 2002-04-12 Akim Demaille <akim@epita.fr>

10789 2002-04-10 Akim Demaille <akim@epita.fr>
10791 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Install the Zsh
10792 workaround for ${1+"$@"}.
10793 * doc/autoconf.texi (Shell Substitutions): Explain it.
10794 From Oliver Kiddle and Peter Stephenson.
10796 Have M4sh perform minimal shell sanitizing.
10798 * lib/m4sugar/m4sh.at (AS_SHELL_SANITIZE): Split the `_AS_PREPARE_*'
10799 part into...
10800 (_AS_PREPARE): this new macro.
10801 (AS_PREPARE): New.
10802 (AS_INIT): Invoke AS_SHELL_SANITIZE.
10803 * tests/m4sh.at (AT_DATA_LINENO): Use _AS_PREPARE.
10805 Adjust Autoconf and Autotest.
10807 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Don't invoke
10808 AS_SHELL_SANITIZE, AS_INIT did it, but invoke AS_PREPARE.
10809 * lib/autotest/general.m4 (AT_INIT): Likewise.
10810 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
10811 Invoke _AS_PREPARE (not AS_PREPARE) in addition to
10812 AS_SHELL_SANITIZE.
10814 Use this M4sh to generate Autoconf's shell scripts.
10816 * tests/wrapsh.as: New, precursor of wrapsh.in.
10817 * tests/Makefile.am: Include lib/freeze.mk to get the dependencies
10818 on Autotest and M4sh.
10819 ($(TESTSUITE)): Use $(autotest_m4f_dependencies).
10820 (wrapsh.in): New target.
10821 * bin/autoconf.as: New, precursor of autoconf.in.
10822 (autoconf.in): New target.
10824 2002-04-09 Alexandre Duret-Lutz <duret_g@epita.fr>
10826 * doc/autoconf.texi (Limitations of Make): Mention the issue
10827 with indented comments in rules.
10829 2002-04-09 Andreas Schwab <schwab@suse.de>
10831 * lib/autoconf/status.m4 (_AC_SRCPATHS): Handle empty
10832 ac_top_builddir when setting ac_abs_top_builddir.
10834 2002-04-06 Kevin Ryde <user42@zip.com.au>
10836 * doc/autoconf.texi (Systemology): Add link to Unix V7 online docs.
10837 (Portable Shell): Cross reference to Systemology.
10839 2002-04-05 Akim Demaille <akim@epita.fr>
10841 * bin/autoreconf.in (autoreconf): Be sure to accumulate the
10842 directories when descending in a SUBDIRS.
10843 Reported by Ezra Peisach.
10845 2002-04-04 Andreas Schwab <schwab@suse.de>
10847 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Only simplify if path
10848 contains no literal separators.
10850 2002-04-03 Akim Demaille <akim@epita.fr>
10852 * lib/autoconf/status.m4 (_AC_CONFIG_FILE, _AC_CONFIG_HEADER)
10853 (_AC_CONFIG_COMMAND, _AC_CONFIG_LINK): New.
10854 Use dnl, not the KILL diversion.
10855 Extracted from...
10856 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_COMMANDS)
10857 (AC_CONFIG_LINKS): here.
10858 Adjust.
10859 Don't use the KILL diversion, as it kills spurious output, which
10860 results in failures being hidden.
10861 Use m4_defn where appropriate.
10862 (AC_CONFIG_IF_MEMBER): Kill the real bug: a spurious parenthesis
10863 after the second argument.
10864 Use m4_defn.
10865 * lib/autom4te.in (Autoconf, Autotest, M4sh): Don't pass --warning
10866 syntax, as it is provided by M4sugar.
10867 * tests/torture.at (Multiple AC_CONFIG_FILES): New.
10869 2002-04-03 Andreas Schwab <schwab@suse.de>
10871 * lib/m4sugar/m4sugar.m4 (m4_bmatch): Make sure m4_bregexp is not
10872 expanded if $# <= 2.
10874 * bin/autoreconf.in (autoreconf): Run automake after rerunning
10875 aclocal.
10877 2002-04-03 Akim Demaille <akim@epita.fr>

10882 (_AC_COMPILER_EXEEXT_DEFAULT, _AC_COMPILER_EXEEXT_O)
10883 (_AC_COMPILER_OBJEXT): Use them.
10884 Fixes Debian #138666.
10886 2002-04-02 Peter Eisentraut <peter_e@gmx.net>
10888 Integrate AC_PROG_CC_STDC into AC_PROG_CC.
10890 * lib/autoconf/c.m4 (AC_PROG_CC_STDC): Rename to _AC_PROG_CC_STDC.
10891 AU_DEFUN old name. Use _AC_COMPILE_IFELSE.
10892 (AC_PROG_CC): Call _AC_PROG_CC_STDC.
10893 (AC_C_INLINE): Do not require AC_PROG_CC_STDC.
10894 (AC_C_CONST): Same.
10895 (AC_C_INLINE): Same.
10896 (AC_C_PROTOTYPES): Same. Require AC_PROG_CC instead.
10897 * doc/autoconf.texi, NEWS: Document.
10898 * tests/mktests.sh (au_exclude_list): Add AC_PROG_CC_STDC and
10899 AC_C_CROSS.
10901 2002-04-02 Akim Demaille <akim@epita.fr>
10903 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Invoke
10904 _AS_MKDIR_P_PREPARE.
10906 2002-03-28 Kevin Ryde <user42@zip.com.au>
10908 * lib/autoconf/c.m4 (AC_C_INLINE): Test with a typedef return value,
10909 to avoid versions of HP C which don't allow that.
10911 2002-03-27 Paul Eggert <eggert@twinsun.com>
10913 * lib/m4sugar/m4sh.m4 (_AS_BASENAME_PREPARE): New macro.
10914 (AS_SHELL_SANITIZE): Invoke it.
10915 (AS_BASENAME): AS_REQUIRE it, and use $as_basename.
10917 2002-03-26 Akim Demaille <akim@epita.fr>
10919 * doc/autoconf.texi (Portable Shell): Add pointers to FAQs.
10921 2002-03-26 Akim Demaille <akim@epita.fr>
10923 * doc/autoconf.texi (Introduction): The GNATS base moved.
10925 2002-03-25 Paul Eggert <eggert@twinsun.com>
10927 * tests/m4sh.at: Don't rely on "PATH=test:$PATH test-1" working
10928 as POSIX requires, as it doesn't work with Zsh.
10929 * doc/autoconf.texi (Assignments): Document the problem.
10931 2002-03-25 Alexandre Duret-Lutz <duret_g@epita.fr>
10933 * doc/autoconf.texi (Limitations of Make): Mention more issue
10934 about VPATH, overriding of macros in sub-makes, and handling of
10935 SHELL.
10937 2002-03-21 Paul Eggert <eggert@twinsun.com>
10939 * doc/autoconf.texi (Here-Documents): Mention Solaris 8 dtksh
10940 problem with here-document buffer boundaries.
10942 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Unset ENV and BASH_ENV
10943 when reinvoking the shell, to work around problems with installers
10944 who put strange things like "cd" commands in their environments.
10946 2002-03-19 Akim Demaille <akim@epita.fr>
10948 * tests/semantics.at (AC_C_BIGENDIAN): s/unknow/unknown/.
10949 From Aaron Ucko.
10951 2002-03-19 Akim Demaille <akim@epita.fr>
10953 * bin/autoscan.in (scan_file): Specify the location in `&used'
10954 invocations.
10955 From Nicolas Joly.
10957 2002-03-19 Akim Demaille <akim@epita.fr>
10959 * doc/autoconf.texi: Adjust @code/@command, @xref/@ref usage.
10960 From Nishio Futoshi.
10962 2002-03-19 Akim Demaille <akim@epita.fr>
10964 * lib/m4sugar/m4sugar.m4 (m4_define_default, m4_fst, m4_map): New.
10966 2002-03-18 Paul Eggert <eggert@twinsun.com>
10968 * doc/autoconf.texi (Programming in M4sh): Add AS_MKDIR_P.
10969 (Limitations of Usual Tools): Add mkdir section.
10971 * lib/m4sugar/m4sh.m4 (_AS_MKDIR_P_PREPARE): New macro.
10972 (AS_MKDIR_P): Require it. Use mkdir -p if available, falling
10973 back on AS_DIRNAME to compute prefixes otherwise; this is
10974 roughly what mkinstalldirs does. That way, we need not have
10975 our own filename disassembler. The old disassembler did not
10976 work with Solaris 8 dtksh, which is ksh Version M-12/28/93d.
10978 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP):
10979 Create at_test_all by a series of assignments,
10980 not by a single assignment of a long string. The latter causes ksh
10981 version 11/16/88g to silently misbehave on OpenServer 5.0.6a,
10982 presumably because of a buffer overrun.
10984 2002-03-14 Paul Eggert <eggert@twinsun.com>
10986 * lib/autotest/general.m4 (at_times_skip):
10987 Renamed from at_times. Now a boolean.
10988 ksh93 Version M-12/28/93d doesn't like 'x=times; $x'; it
10989 says 'times: not found'.
10991 2002-03-14 Akim Demaille <akim@epita.fr>
10993 * bin/autoreconf.in (&study_gettextize): New.
10994 (&autoreconf): Handle newest gettextize.
10995 Rerun aclocal if needed.
10996 Suggested by Andreas Schwab.
10998 2002-03-13 Akim Demaille <akim@epita.fr>
11000 * doc/autoconf.texi (Special Shell Variables): More about IFS.

11007 2002-03-13 Akim Demaille <akim@epita.fr>
11009 * doc/autoconf.texi (Limitations of Usual Tools): Some about `cp
11010 -p'.
11011 From Bob Proulx.
11013 2002-03-12 Akim Demaille <akim@epita.fr>
11015 * lib/m4sugar/m4sh.m4 (AS_BASENAME_EXPR): AS_REQUIRE, not
11016 m4_require.
11018 2002-03-11 Andreas Schwab <schwab@suse.de>
11020 * configure.ac: Explicitly check for EMACS since AM_PATH_LISPDIR
11021 does not do it if --with-lispdir is given.
11023 2002-03-08 Akim Demaille <akim@epita.fr>
11025 Version 2.53.
11027 2002-03-08 Akim Demaille <akim@epita.fr>
11029 * doc/autoconf.texi (Subdirectories): Clarify that the
11030 subdirectory should exist.
11032 2002-03-08 Akim Demaille <akim@epita.fr>
11034 * Makefile.am (AUTOMAKE_OPTIONS): 1.6.
11036 2002-03-08 Akim Demaille <akim@epita.fr>
11038 * bin/autom4te.in (&handle_m4): Do not foreach with `$_' as it
11039 aliases the actual variables, and modifications of the former
11040 affect the latter.
11042 2002-03-08 Akim Demaille <akim@epita.fr>
11044 * bin/autom4te.in (&handle_m4): Protect us from corrupted file
11045 because of C-c: have m4 output in tmp files, then mv them.
11047 2002-03-08 Akim Demaille <akim@epita.fr>
11049 * bin/autoconf.in, bin/autoheader.in, bin/autom4te.in,

11062 2002-03-05 Akim Demaille <akim@epita.fr>
11064 Version 2.52i.
11066 2002-03-04 Akim Demaille <akim@epita.fr>
11068 * doc/autoconf.texi (AC_LIBOBJ vs. LIBOBJS): New.
11069 * lib/autoconf/general.m4 (AC_INIT): More informative error
11070 message for LIBOBJ.
11072 2002-03-04 Akim Demaille <akim@epita.fr>
11074 * lib/freeze.mk ($(build_libdir)/m4sugar/version.m4): New, for
11075 parallel builds.
11077 2002-03-04 Akim Demaille <akim@epita.fr>
11079 * doc/autoconf.texi (Transforming Names): Equality between target
11080 and host is irrelevant.
11081 (Specifying Names, Canonicalizing): Remove all references to the
11082 backward compatibility hooks. Rather, collect them all into...
11083 (Hosts and Cross-Compilation): this new section.
11084 * doc/install.texi (System Type): Ditto.
11085 * lib/autoconf/general.m4 (AC_CANONICAL_HOST): Explicitly state
11086 that `--host' implies cross-compilation.
11088 2002-03-04 Akim Demaille <akim@epita.fr>
11090 * doc/autoconf.texi (Evaluation Macros): New.
11091 * lib/m4sugar/m4sugar.m4 (m4_lquote): Remove, it is totally
11092 useless.
11093 (_m4_foreach): Define the variant with immediate evaluation so
11094 that it contains exactly the items, not an expression which
11095 evaluation is the current item.
11096 (m4_re_string, m4_re_word): Don't over quote them.
11098 2002-03-04 Akim Demaille <akim@epita.fr>
11100 Instead of having stacking `shift's evaluated at the end, let
11101 `foreach' loops immediately evaluate them.
11103 * lib/m4sugar/m4sugar.m4 (m4_quote, m4_dquote): Use $@ rather than
11104 $*. This is the n-th time I change my mind, but hopefully this is
11105 the last...
11106 (m4_lquote): New.
11107 (m4_text_wrap): Use m4_foreach, which is finally correct _and_
11108 efficient.
11109 (m4_foreach_quoted, m4_car_quoted, _m4_foreach_quoted): Remove, as
11110 it was only a hack for m4_text_wrap.
11111 (m4_car2): Remove, replaced by...
11112 (m4_cdr): New.
11113 (_m4_foreach): Adjust.
11114 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Adjust, and use
11115 m4_bpatsubst for clarification.
11117 2002-03-04 Akim Demaille <akim@epita.fr>
11119 * doc/autoconf.texi (Changequote is Evil): New.
11121 2002-03-03 Kevin Ryde <user42@zip.com.au>
11123 * doc/autoconf.texi (Portable Shell): Mention 32-byte #! length limit
11124 on old systems like SunOS.

11146 From Akinori Musha.
11148 2002-02-13 Alexandre Duret-Lutz <duret_g@epita.fr>
11150 * lib/Autom4te/XFile.pm (getline, getlines): New functions,
11151 translate \r\n to \n.
11153 2002-02-07 Akim Demaille <akim@epita.fr>
11155 Version 2.52h.
11157 2002-02-07 Akim Demaille <akim@epita.fr>
11159 Fix Autoconf PR/209.
11160 Also reported by Frank Denis.

11164 2002-02-07 Akim Demaille <akim@epita.fr>
11166 Fix Autoconf PR/207:
11167 AC_PREFIX_PROGRAM fails with dashed program names
11169 * lib/autoconf/general.m4 (AC_PREFIX_PROGRAM): Just use a fresh
11170 variable when looking for the prefix program.
11171 Now it also works for shell variables.
11173 2002-02-07 Akim Demaille <akim@epita.fr>
11175 * doc/autoconf.texi (Limitations of Builtins): More about
11176 case/esac.

11180 * lib/autoconf/status.m4 (_AC_OUTPUT_COMMANDS): Don't output empty
11181 case/esac, some shells don't support it.
11182 Reported by Zack Weinberg.
11183 * tests/torture.at (AC_CONFIG_COMMANDS with empty commands): New.
11185 2002-02-06 Akim Demaille <akim@epita.fr>
11187 * lib/autotest/general.m4 (AT_INIT): When handling --keywords, be
11188 sure not to introduce newlines in at_groups.
11189 * lib/autotest/Makefile.am (autotest.m4f): Typo.
11191 2002-02-06 Akim Demaille <akim@epita.fr>
11193 * tests/torture.at (Configuring subdirectories): Skip if aclocal
11194 is not available.
11196 2002-02-05 Paul Eggert <eggert@twinsun.com>
11198 * doc/autoconf.texi (Specific Compiler Characteristics):
11199 Describe HP-UX cc bug workaround more accurately.
11200 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Cast to long,
11201 not unsigned long.
11202 * tests/semantics.at (AC_CHECK_SIZEOF): Check non-GCC
11203 cross-compilers, too. This undoes some of the most recent change
11204 to this file.
11206 2002-02-05 Akim Demaille <akim@epita.fr>
11208 * tests/Makefile.am (check_SCRIPTS): Use it, instead of WRAPPERS,
11209 to make sure they are up to date when `check' is run.
11211 2002-02-05 Akim Demaille <akim@epita.fr>
11213 * doc/autoconf.texi (Making testsuite Scripts): Document
11214 package.m4.

11218 * lib/freeze.mk: New.
11220 2002-02-05 Akim Demaille <akim@epita.fr>
11222 Implement `autom4te --freeze'.
11224 * bin/autom4te.in (&freeze): New.
11225 * lib/autoconf/autoconf.m4, lib/autotest/general.m4,
11226 * lib/m4sugar/m4sh.m4: Don't include files given by autom4te.
11228 2002-02-05 Akim Demaille <akim@epita.fr>
11230 * bin/autom4te.in (&parse_args): Implement `frozen files are
11231 optional are the sum of the previous files on the command line'.
11232 Also, pass `--reload-state=' on them, so...
11233 (handle_m4): don't.
11234 * lib/autom4te.in (Autotest, Autoconf): Rely on M4sh.
11235 (M4sh): Rely on M4sugar.
11236 (Autotest, M4sh, M4sugar): Use frozen files.
11238 2002-01-31 Akim Demaille <akim@epita.fr>
11240 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Accept $4.
11241 * doc/autoconf.texi (Initializing configure): Adjust.
11243 2002-01-30 Akim Demaille <akim@epita.fr>
11245 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Map non
11246 alphanumeric to `-' instead of `_'.
11248 2002-01-30 Akim Demaille <akim@epita.fr>
11250 * tests/semantics.at (AC_CHECK_SIZEOF): Split into two tests: one
11251 for plain code, the other for cross-compilation code. The latter
11252 is now run with GCC only.
11253 * doc/autoconf.texi (Compilers and Preprocessors): New.
11255 2002-01-30 Akim Demaille <akim@epita.fr>
11257 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Support pre-defined
11258 values.
11259 * doc/autoconf.texi (Initializing configure): Explain how to
11260 change AC_INIT default values.
11262 2002-01-29 Akim Demaille <akim@epita.fr>

11265 so that aclocal 1.4 works.
11266 Reported by Alexandre Duret-Lutz and Larry Schmitt.
11268 2002-01-28 Akim Demaille <akim@epita.fr>
11270 * doc/autoconf.texi (Writing testsuite.at): AT_CLEANUP no longer
11271 needs an argument.
11273 2002-01-28 Akim Demaille <akim@epita.fr>
11275 * lib/autotest/general.m4 (AT_INIT): Don't be ridiculous: adjust
11276 AUTOTEST_PATH *after* it was set.
11277 Don't put `.' in the PATH: the user should be precise and `./' if
11278 needed. In addition, given that the test suite does some `cd', if
11279 `.' is in the path, the `tested programs' sections will report
11280 programs found in the test suite's directory, while during the
11281 tests (performed in their own directory), these programs are no
11282 longer visible. In other words, the results is confusing and
11283 useless.
11284 * tests/m4sh.at: Adjust: don't rely on `.' being in the PATH.
11286 2002-01-24 Akim Demaille <akim@epita.fr>
11288 Version 2.52g.

11295 2002-01-24 Akim Demaille <akim@epita.fr>
11297 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Use PATH_SEPARATOR.
11298 (_AS_PATH_SEPARATOR_PREPARE): Don't expect $SHELL to be
11299 Bourne. Use /bin/sh.
11300 From Andreas Buening.
11302 2002-01-24 Akim Demaille <akim@epita.fr>
11304 * config/config.guess, config/config.sub, config/texinfo.tex:

11314 Automake.
11316 2002-01-24 Akim Demaille <akim@epita.fr>
11318 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS)
11319 (_AC_INIT_PREPARE): Support -n as --no-create, as documented.
11320 Reported by Geir Ove Myhr.
11322 2002-01-21 Akim Demaille <akim@epita.fr>
11324 * lib/autoconf/functions.m4 (AC_FUNC_MMAP): #Undef malloc.
11326 2002-01-21 Akim Demaille <akim@epita.fr>
11328 * lib/Autom4te/General.pm (getopt): Use a more GNUish error
11329 message on invalid options.
11330 * bin/autom4te.in (parse_args): Don't use
11331 Autoconf::General::getopt with non valid options.
11333 2002-01-17 Jim Meyering <meyering@lucent.com>
11335 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Initialize
11336 $ac_cv_exeext so we don't use an old, invalid, cached value.
11338 2002-01-11 Akim Demaille <akim@epita.fr>
11340 * lib/autoconf/functions.m4 (AC_FUNC_STRNLEN): New, from Jim
11341 Meyering.

11343 limitation.
11344 (Particular Functions): Document AC_FUNC_STRNLEN.

11347 2002-01-06 Akim Demaille <akim@epita.fr>
11349 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Don't create
11350 package.m4, since is really depends upon configure.ac, not
11351 configure.
11352 * doc/autoconf.texi (testsuite Scripts): Adjust.
11353 * tests/Makefile.am (package.m4): New.
11354 EXTRA_DIST it since its a source.
11356 2002-01-06 Akim Demaille <akim@epita.fr>
11358 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Move the AC_SUBST
11359 of PACKAGE_NAME, PACKAGE_TARNAME, PACKAGE_VERSION, PACKAGE_STRING,
11360 and PACKAGE_BUGREPORT from here...
11361 (_AC_INIT_DEFAULTS): to here, since it is unrelated to the
11362 arguments.
11363 (_AC_INIT_PREPARE): AC_DEFINE these symbols.
11364 * lib/autotest/general.m4: Use AT_PACKAGE_*, not PACKAGE_*.
11365 (AT_INIT): No longer catch `^PACKAGE_(BUGREPORT|STRING)$'.
11366 * tests/tools.at (autoheader): Adjust.
11367 * tests/atspecific.m4 (AT_CHECK_DEFINES): Adjust.
11369 2002-01-06 Akim Demaille <akim@epita.fr>

11373 2002-01-03 Akim Demaille <akim@epita.fr>
11375 * doc/autoconf.texi (Output): Improved wording regarding use of
11376 AC_OUTPUT.
11377 From Olly Betts.
11379 2001-12-18 Kevin Ryde <user42@zip.com.au>
11381 * doc/autoconf.texi (Function Portability): Add notes on sscanf
11382 sometimes needing writable input.
11384 2001-12-17 Jim Meyering <meyering@lucent.com>
11386 * doc/autoconf.texi (New Macros): Tweak wording.
11388 2001-12-14 Akim Demaille <akim@epita.fr>
11390 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): We cleaning up the
11391 trailing files, don't apply `-rf' to files which might not be
11392 created by configure (core, core.*, and *.core), but just `rm -f'.
11393 Suggested by Jonathan Kamens.
11395 2001-12-14 Aaron M. Ucko <amu@alum.mit.edu>
11397 * lib/autoconf/general.m4: Avoid duplicates in `$ac_configure_args'.
11399 2001-12-14 Akim Demaille <akim@epita.fr>
11401 * Makefile.am (MAINTAINERCLEANFILES): Remove configure.
11403 2001-12-13 Peter Eisentraut <peter_e@gmx.net>
11405 * lib/autoconf/status.m4 (_AC_SRCPATHS): Rename buildpath to
11406 abs_builddir, top_buildpath to abs_top_builddir, srcpath to
11407 abs_srcdir, top_srcpath to abs_top_srcdir.
11408 (_AC_OUTPUT_FILES): Adjust.
11409 * NEWS, doc/autoconf.texi, lib/autoconf/autotest.m4,
11410 * tests/atspecific.m4, tests/autoreconf.in, tests/tools.at,
11411 * tests/wrappl.in, tests/wrapsh.in: Adjust.
11413 2001-12-12 Steven G. Johnson <stevenj@alum.mit.edu>
11415 * lib/autoconf/fortran.m4 (_AC_PROG_F77_V_OUTPUT): Fix failed
11416 C/Fortran linking on HP/UX, by extracting the Fortran library
11417 search path from the LPATH line in the $F77 -v output.
11419 2001-12-12 Kevin Ryde <user42@zip.com.au>
11421 * doc/autoconf.texi (File Descriptors): Use a clearer layout for the
11422 forbidden file descriptors table.
11424 2001-11-26 Akim Demaille <akim@epita.fr>
11426 * bin/autoscan.in (%c_keywords): Build it at top level.
11427 Map to 1 in order to simplify its uses.
11429 2001-11-26 Akim Demaille <akim@epita.fr>
11431 * bin/autoscan.in (&scan_c_file, &scan_sh_file, &scan_makefile):
11432 Remove $filepath, useless.
11433 (&scan_makefile): Don't remove the $(FOO), ${FOO} and @FOO@
11434 variables, they are really part of the tokens.
11435 Split the input line on spaces and then look for tokens.
11436 Now autoscan ceases to ask for AC_PROG_LEX for the package Bison
11437 because of `lex$U.$(OBJEXT)'.
11438 (&scan_files): Use "@list" instead of join.
11439 * doc/Makefile.am (CLEANFILES): Add *.fns.
11441 2001-11-26 Akim Demaille <akim@epita.fr>
11443 * tests/autoreconf.in, tests/autom4te.in, tests/autoupdate.in:
11444 Remove, replaced by...
11445 * tests/wrappl.in: Be common for all the Perl executables.
11446 In particular autoscan and autoheader want -I.
11447 * configure.ac: Adjust.
11448 * lib/autoscan/headers: errno.h is portable.
11450 2001-11-26 Akim Demaille <akim@epita.fr>
11452 * bin/autoscan.in (used): New.
11453 Use it.
11455 2001-11-26 Akim Demaille <akim@epita.fr>
11457 * bin/autoscan.in (&scan_c_file): Better parsing of CPP
11458 directives.
11459 (&scan_sh_file): Remove a duplicate pattern.
11460 (&check_configure_ac): Use long options.

11466 Before, having a line containing the opening of a multi line
11467 comment made the whole line be ignored.
11469 2001-11-26 Akim Demaille <akim@epita.fr>
11471 * doc/autoconf.texi (Using an Autotest Test Suite): New.
11472 (testsuite Scripts): Be one of its subsection.
11473 (Autotest Logs): New.
11475 2001-11-26 Akim Demaille <akim@epita.fr>
11477 Test groups are now run two directories deeper.
11479 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Replace srcdir,
11480 top_srcdir and top_builddir with at_srcdir, at_top_srcdir and
11481 at_top_builddir.
11482 * lib/autotest/general.m4 (AT_INIT): Compute srcdir,
11483 top_srcdir, builddir and top_builddir.
11484 Use `at_*dir' relatively to the directory containing the
11485 suite, use `*dir' when relatively to the current group dir.
11487 2001-11-25 Joseph S. Myers <jsm28@cam.ac.uk>
11489 * doc/autoconf.texi, TODO, lib/autoconf/fortran.m4,
11490 lib/autoconf/functions.m4, lib/autoconf/headers.m4,
11491 tests/atgeneral.m4, tests/tools.at, tests/atspecific.m4: Fix
11492 spelling errors.
11494 2001-11-22 Alexandre Duret-Lutz <duret_g@epita.fr>
11496 * doc/autoconf.texi (Using System Type): Add an example of `case
11497 $host' usage so people quit using `case $target' everywhere.
11499 2001-11-22 Akim Demaille <akim@epita.fr>
11501 * doc/autoconf.texi (Installation Directory Variables): Englishoes
11502 spotted by Jim Meyering.
11504 2001-11-16 Paul Eggert <eggert@twinsun.com>
11506 This patch implements a `long double' suggestion by Oliver Kiddle.
11508 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C)): Make the array
11509 static, to catch errors if the value isn't known at compile-time
11510 and the compiler supports dynamic arrays. Change its name from
11511 `_array_' to `test_array' to avoid potential name clashes.
11512 (AC_C_LONG_DOUBLE): Make it a compile-time test, not a run-time
11513 test. Do not define HAVE_LONG_DOUBLE if `long double' is no
11514 better than double. Catch a bug in GCC 2.95.2 x86.
11515 * doc/autoconf.texi (C Compiler): Document the above.
11516 * NEWS: Likewise.
11518 2001-11-13 Akim Demaille <akim@epita.fr>
11520 * tests/m4sh.at (LINENO): Protect from autom4te's substitution by
11521 hand.
11522 * tests/tools.at: Don't protect dnl, AT_DATA_M4SH does.
11524 2001-11-13 Akim Demaille <akim@epita.fr>
11526 * lib/autotest/general.m4 (AT_INIT): After having run the test
11527 group, go back to the initial directory, not to at_suite_dir.
11529 2001-11-13 Akim Demaille <akim@epita.fr>
11531 * tests/atspecific.m4 (AT_DATA_M4SUGAR, AT_DATA_M4SH)
11532 (AT_DATA_AUTOCONF): Also protect @&t@ from autom4te.
11533 (AT_CHECK_AUTOCONF, AT_CHECK_AUTOHEADER): Pass no --include
11534 option.
11535 (AT_CHECK_CONFIGURE): Use absolute paths.
11536 (_AT_CHECK_AC_MACRO): Create aclocal.m4 with AC_STATE_SAVE in it.
11537 The problem is still the old one: there is no means in M4 (that I
11538 know about) to create a defining macro, because there is no means
11539 to create `$1' etc., therefore, the defining macro ``swallows''
11540 all the arguments meant to the defined macro.
11542 2001-11-13 Akim Demaille <akim@epita.fr>
11544 * tests/atspecific.m4 (AT_DATA_AUTOCONF): New.
11545 (AT_CONFIGURE_AC): Output the definition of AC_STATE_SAVE in
11546 configure.ac.
11547 * tests/aclocal.m4: Remove, as it is no longer used.
11549 2001-11-13 Akim Demaille <akim@epita.fr>
11551 * lib/autotest/general.m4: Change `tests?' into `groups?' in
11552 variable names when referring to a single test group, or to
11553 `suite' when referring to the whole test suite.
11554 `at_last_test' is removed: m4 compute at_format itself.
11555 (at_stdout, at_stder1, at_stderr): New variables.
11556 (AT_CHECK): Use them.
11558 2001-11-13 Akim Demaille <akim@epita.fr>
11560 * lib/autotest/general.m4 (AT_INIT): Be sure to put `.', relative,
11561 in PATH.
11562 Create `testsuite.dir/003/run' instead of `testsuite.003'.
11563 Do it as soon as a test fails, don't wait till the end of the test
11564 suite.
11565 Don't remove $as_me.[0-9]*, since these files no longer exist.
11567 2001-11-13 Akim Demaille <akim@epita.fr>
11569 * tests/tools.at: Use absolute paths, since we are no longer run
11570 in place.
11572 2001-11-13 Akim Demaille <akim@epita.fr>
11574 Now that tests are running in their own private dir, there is no
11575 need to list the files to remove at the end of tests groups.
11577 * lib/autotest/general.m4 (_AT_CLEANUP_FILE, AT_CLEANUP_FILES):
11578 (AT_data_files, at_data_files): Remove.
11579 (AT_CLEANUP, AT_DATA): Simplify.
11580 (AT_INIT): Adjust.
11581 Remove the group dir if !debug && !failed.
11582 * tests/atspecific.m4: Adjust.
11584 2001-11-13 Akim Demaille <akim@epita.fr>
11586 Start a new layout for Autotest: `testsuite' creates
11587 `testsuite.dir' in which the at-check-line etc. files are to be
11588 found, and `testsuite.dir/003' where the test group 3 is run.
11590 * lib/autotest/general.m4 (AT_INIT): at_tests_dir,
11591 at_check_line_file, at_format, at_test_normalized, at_group_dir
11592 are new variables.
11593 Create the directories.
11594 Use absolute paths for at- files.
11595 (AT_CHECK): Adjust.
11597 2001-11-11 Michael Matz <matz@kde.org>
11599 * m4sugar.m4 (_m4_foreach): Make it linear instead quadratic.
11600 (m4_car2): New.
11601 (m4_car): Properly quote arguments.
11603 2001-11-13 Akim Demaille <akim@epita.fr>
11605 * tests/aclocal.m4 (AC_STATE_SAVE): s/LIBOBJS/LIB@&t@OBJS/ to cope
11606 with stricter rules on LIBOBJS.
11608 2001-11-12 Paul Eggert <eggert@twinsun.com>
11610 * lib/autoconf/c.m4 (AC_C_PROTOTYPES): Define __PROTOTYPES too.
11611 * doc/autoconf.texi (C Compiler): AC_C_PROTOTYPES now defines
11612 __PROTOTYPES too.
11614 2001-11-12 Akim Demaille <akim@epita.fr>
11616 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT): Use AC_CHECK_FUNCS.
11618 2001-11-12 Akim Demaille <akim@epita.fr>
11620 * lib/autoconf/c.m4, lib/autoconf/fortran.m4,
11621 * lib/autoconf/functions.m4, lib/autoconf/general.m4,
11622 * lib/autoconf/headers.m4, lib/autoconf/libs.m4,
11623 * lib/autoconf/programs.m4, lib/autoconf/specific.m4,
11624 * lib/autoconf/types.m4: When invoking AC_DEFINE and friends,
11625 specify to what the macro should be defined (typically to 1).
11627 2001-11-12 Akim Demaille <akim@epita.fr>
11629 * lib/autoconf/functions.m4 (AC_FUNC_STRTOD): AC_SUBST POW_LIB.
11630 From Jim Meyering.
11632 2001-11-12 Akim Demaille <akim@epita.fr>
11634 * lib/autoconf/programs.m4 (_AC_PROG_LEX_YYTEXT_DECL): Use
11635 AC_TRY_EVAL to run $LEX, not AC_TRY_COMMAND. This validates the
11636 definition used by Automake where LEX is +/- "${missing} lex" and
11637 `missing' itself contains variables.
11639 2001-11-12 Akim Demaille <akim@epita.fr>
11641 * lib/autotest/general.m4 (AT_INIT): Push KILL at the end.
11642 Now that M4sh pushes BODY, the comments were output at the end of
11643 the test suites.
11645 2001-11-08 Akim Demaille <akim@epita.fr>
11647 * bin/autoreconf.in (&autoreconf): Run aclocal before tracing, so
11648 that we can trace macros from aclocal.m4.
11649 Trace AC_PROG_LIBTOOL, not AM_PROG_LIBTOOL, since the latter is
11650 obsoleted, and redirect to the former anyway.
11651 Reported by Ralf Corsepius.
11653 2001-11-08 Akim Demaille <akim@epita.fr>
11655 * bin/autoreconf.in (&autoreconf): AC_CONFIG_SUBIDRS are to be
11656 processed only if present.
11657 * tests/torture.at (Configuring subdirectories): Use autoreconf
11658 instead of successive calls to autoconf.
11659 Add a nonexistent subdirectory to exercise the patch above.
11660 Reported by Ralf Corsepius.
11662 2001-11-08 Kevin Ryde <user42@zip.com.au>
11664 * doc/autoconf.texi (Limitations of Usual Tools): Note HP-UX cc
11665 doesn't accept .S files.

11671 (_AC_LIBOBJ): s/LIBOBJS/LIB@&t@OBJS/.
11672 * bin/autom4te.in (warn_forbidden): New.
11673 (handle_output): Use it.
11674 Read m4_pattern_forbid with messages.
11676 2001-11-05 Akim Demaille <akim@epita.fr>
11678 * bin/autom4te.in (--normalize): Remove.
11679 * lib/autom4te.in: Adjust.
11681 2001-11-05 Akim Demaille <akim@epita.fr>
11683 * tests/Makefile.am (testsuite): Rename this target as...
11684 ($(TESTSUITE)): this.
11685 From Nicolas Joly.
11687 2001-11-05 Alexandre Duret-Lutz <duret_g@epita.fr>
11689 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): When removing
11690 the --prefix option, also remove it's argument.
11692 2001-11-05 Akim Demaille <akim@epita.fr>
11694 * doc/autoconf.texi (testsuite Invocation): Update.
11695 (Writing testsuite.at): Update.
11697 2001-11-03 Akim Demaille <akim@epita.fr>
11699 * doc/autoconf.texi: s/@code/@command/ where appropriate.
11701 2001-11-03 Akim Demaille <akim@epita.fr>
11703 * lib/Autom4te/General.pm: (&catfile, &canonfile)
11704 (&file_name_is_absolute): New, wrappers around routines from
11705 File::Spec.
11706 Use and export them.
11707 (&find_configure_ac): Optionally take a directory where to look at.
11708 * bin/autoreconf.in (&parse_args): Trim the configure.ac part of
11709 the arguments.
11710 Default @ARGV to `.', not find_configure_ac.
11711 (&autoreconf): Argument is a directory.
11712 Trace AC_CONFIG_SUBDIRS and schedule the subdirs for autoreconf'ing.
11713 * doc/autoconf.texi (autoreconf Invocation): Update.
11715 2001-11-03 Akim Demaille <akim@epita.fr>
11717 * lib/Autom4te/General.pm (@export_vars, @export_subs)
11718 (@export_forward_subs): New.
11719 Add basename, dirname, and fileparse.
11720 (@EXPORT): Adjust.
11721 * bin/autoreconf.in (&autoreconf): Fix call to fileparse.
11722 Don't look for aclocal flags if we already know aclocal is not
11723 used.
11724 Move aclocal.m4t only if it exists.
11725 Reported by Ezra Peisach.
11727 2001-11-03 Akim Demaille <akim@epita.fr>
11729 * bin/autoreconf.in (&parse_args): Work only on the configure.ac
11730 passed on command line, defaulting to ./configure.ac if present.
11731 (&maybe_autoreconf, File::Find): Remove, unused.
11732 (&autoreconf): If autoconf is not used, don't try to trace.
11734 2001-11-02 Akim Demaille <akim@epita.fr>
11736 * configure.ac: Bump to 2.52g.
11738 2001-11-02 Akim Demaille <akim@epita.fr>
11740 Version 2.52f.
11742 2001-11-02 Akim Demaille <akim@epita.fr>
11744 * config/config.guess, config/config.sub, doc/standards.texi:
11745 * config/lispdir.m4: Update from masters.
11746 * configure.ac: Bump to 2.52f.
11748 2001-11-02 Akim Demaille <akim@epita.fr>
11750 * bin/autoreconf.in (&autoreconf): Set `$aclocal_flags' to ''.
11751 Don't run aclocal when aclocal.m4 is not from aclocal.
11752 From Ezra Peisach.
11753 Don't run libtoolize and gettextize if --install is not given.
11755 2001-11-01 Paul Eggert <eggert@twinsun.com>
11757 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): _AS_CR_PREPARE needs to
11758 be invoked before _AS_LINENO_PREPARE.
11759 (_AS_LINENO_PREPARE): Use as_cr_digits and as_cr_alnum rather
11760 than character ranges.
11762 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Fix NLS before
11763 invoking AS_BASENAME. Set the locale variables to 'C' if
11764 possible, as POSIX requires this to get the traditional
11765 behavior.
11766 * doc/autoconf.texi (Special Shell Variables): Describe the above.
11768 2001-10-31 Paul Eggert <eggert@twinsun.com>
11770 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): Do not surround body
11771 with {}, as that triggers a bug in Bash 2.05.
11773 (_AS_LINENO_PREPARE): Use Sed rather than
11774 Awk. Fix the sed prepass to work even if there are multiple
11775 instances of $LINENO on the same line. Do not substitute for
11776 other variables like $LINENOT. Do not check file dates; such a
11777 check is unreliable on sufficiently fast machines, and removing
11778 the check makes the code simpler and more reliable. Check for
11779 output and chmod failures.
11781 * doc/autoconf.texi (Special Shell Variables): Document
11782 the above.
11784 2001-10-31 Akim Demaille <akim@epita.fr>
11786 * tests/Makefile.am (atconfig): Remove this target, Automake
11787 handles it now.
11789 2001-10-31 Akim Demaille <akim@epita.fr>
11791 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Do not
11792 AC_CONFIG_FILES(atlocal) as it means a file atlocal.in *must* be
11793 provided, while it is optional.
11794 * configure.ac: Adjust.
11796 2001-10-26 Paul Eggert <eggert@twinsun.com>
11798 * NEWS, README, configure.ac, lib/Autom4te/General.pm,
11799 lib/Autom4te/Struct.pm:
11800 Require Perl 5.005_03 instead of just 5.005, as some tests fail
11801 with 5.005_02.
11803 * doc/autoconf.texi (Special Shell Variables): Document some
11804 more LINENO gotchas, particularly with respect to the Awk+Sed hack.
11806 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): New macro.
11807 (_AS_LINENO_PREPARE): Use it instead of shell eval, since
11808 eval $LINENO is not portable in practice.
11810 2001-10-24 Akim Demaille <akim@epita.fr>
11812 * lib/Autom4te/General.pm (backname): New.
11814 2001-10-24 Akim Demaille <akim@epita.fr>
11816 * m4/: Remove, merged into...
11817 * config/: here.
11819 2001-10-23 Tim Van Holder <tim.van.holder@pandora.be>
11821 * doc/autoconf.texi (Shellology): Mention the problems with bash
11822 2.05's use of ANSI quoting in its `set' builtin.
11824 2001-10-22 Paul Eggert <eggert@twinsun.com>
11826 * lib/autoconf/functions.m4 (AC_FUNC_STRERROR_R):
11827 Rename ac_cv_func_strerror_r_works to ac_cv_func_strerror_r_char_p,
11828 and rename HAVE_WORKING_STRERROR_R to STRERROR_R_CHAR_P, since
11829 POSIX decided to standardize on the int flavor of strerror_r.
11830 Always do char* test, as there's no reason not to.
11831 Assign to a char* var, to catch strerror_r that returns int*.
11833 * doc/autoconf.texi (Particular Functions):
11834 Document the above changes. Also, document the fact that
11835 AC_FUNC_STRERROR_R defines HAVE_DECL_STRERROR_R.
11837 * NEWS: Mention HAVE_WORKING_STRERROR_R -> STRERROR_R_CHAR_P.
11839 2001-10-20 Akim Demaille <akim@epita.fr>
11841 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): The name of
11842 the executable was missing from the log.

11846 * lib/Autom4te/General.pm (&update_file): If destination is
11847 unchanged, remove the source.
11848 (&up_to_date_p): Don't be verbose, be debug.
11849 * bin/autoreconf.in: No longer support --m4dir.
11850 (&autoreconf): Display the full path of the configure.ac we are
11851 studying.
11852 Trace it only once.
11853 Be sure to honor --force with gettextize.
11854 Always run aclocal.
11855 * doc/autoconf.texi: Adjust.
11857 2001-10-20 Akim Demaille <akim@epita.fr>
11859 * bin/autoheader.in ($localdir, $m4, $SIMPLE_BACKUP_SUFFIX):
11860 Remove, dead.
11861 * bin/autoreconf.in (&autoreconf): Do not run gettextize when
11862 `intl' is already present, as it refuses unless --force.
11863 (&parse_args): Use -I, --include instead of the old Autoconf
11864 options.
11865 ($localdir, $autoconf_dir): Remove.
11866 (@include): New.
11867 (&maybe_autoreconf): New, to preserve $_ for File::Find.
11869 2001-10-19 Jens Petersen <petersen@redhat.com>

11876 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Name the generated
11877 file in @configure_input@.
11878 Don't mention `automatically' in addition to `generated'.
11879 * tests/torture.at (#define header templates): Adjust.
11881 2001-10-19 Akim Demaille <akim@epita.fr>
11883 * lib/emacs/autoconf-mode.el, lib/emacs/autotest-mode.el: In a
11884 comment, explain how to install automatic mode selection.
11885 From Russ Allbery.
11887 2001-10-19 Ezra Peisach <epeisach@zif.mit.edu>
11889 * bin/autoreconf.in (autoreconf): Display the path to the
11890 configure.ac being studied.
11892 2001-10-18 Paul Eggert <eggert@twinsun.com>
11894 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Cast sizeof to unsigned
11895 long, to work around a bug in the HP C compiler version HP92453-01
11896 B.11.11.23709.GP.
11898 * lib/m4sugar/m4sh.m4 (AS_DIRNAME): Use 'dirname' if that works.
11899 (AS_BASENAME_EXPR): New macro.
11900 (AS_BASENAME_SED): Do not assume GNU sed semantics.
11901 (AS_BASENAME): Use 'basename' if that works; then try 'expr';
11902 and fall back on 'sed' only if the other two fail. This makes
11903 AS_BASENAME act more like AS_DIRNAME.
11904 (as_me): Shell-quote the argument of AS_BASENAME, in case $0
11905 contains white space.
11906 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR):
11907 Use AS_DIRNAME, since I think it's now DOS-friendly.
11908 * tests/m4sh.at (DIRNAME_TEST): New arg $3.
11909 Allow "dirname //FOO" to return either / or //, as POSIX allows
11910 either behavior.
11912 2001-10-10 Akim Demaille <akim@epita.fr>
11914 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Recognize

11916 From Eric Sharkey.

11920 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N_PREPARE): m4_defun, not

12015 2001-10-08 Akim Demaille <akim@epita.fr>
12017 Use `add-log-current-defun-function' for ChangeLog creation.

12026 (autoconf-font-lock-keywords): Recognize `m4_defun'.
12028 2001-10-08 Akim Demaille <akim@epita.fr>
12030 * lib/autoconf/general.m4 (_m4_divert(BODY)): Move to...
12031 * lib/m4sugar/m4sh.m4: here.
12032 (AS_INIT): Push the BODY diversion, set the #! /bin/sh line.
12033 * lib/autoconf/general.m4 (AC_PLAIN_SCRIPT) : Remove.
12034 (AT_INIT): Replace AC_PLAIN_SCRIPT with AS_INIT invocation,
12035 include handle the m4_pattern_*, no longer push the
12036 BODY diversion nor set the /bin/sh line, AS_INIT does it.
12037 * lib/autotest/general.m4 (AT_INIT): Likewise.
12038 * tests/base.at: Adjust the tests to use AS_INIT.
12039 * tests/tools.at (AT_DATA_FORBIDDEN): New.

12045 * doc/autoconf.texi (config.status Invocation):
12046 CONFIG_SHELL defaults to a shell that supports LINENO if available.

12049 shell does not support LINENO, and if CONFIG_SHELL is unset or
12050 empty, and if we can find a shell that does support LINENO,
12051 then set CONFIG_SHELL to that shell and then re-execute
12052 ourselves with CONFIG_SHELL.
12054 2001-10-05 Paul Eggert <eggert@twinsun.com>
12056 * tests/Makefile.am (clean-local): Don't invoke $(TESTSUITE) if it
12057 doesn't exist. Remove *.tmp, as a .tmp file is created during the
12058 build of $(TESTSUITE).
12060 2001-10-05 Akim Demaille <akim@epita.fr>
12062 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Look in the path

12083 (AS_SHELL_SANITIZE): here. Use it.
12084 (_AS_LINENO_PREPARE): Preserve the exit status of $0.lineno.
12085 From Paul Eggert.
12087 2001-10-04 Akim Demaille <akim@epita.fr>
12089 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Use a portable
12090 combination of Awk and sed to replace $LINENO.
12092 2001-10-02 Paul Eggert <eggert@twinsun.com>
12094 * doc/autoconf.texi (Limitations of Builtins): You can't use
12095 "source"; it's not portable. Remove confusing and
12096 somewhat-incorrect example involving "." and "/".
12098 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): "source" -> ".", for
12099 compatibility with POSIX shells.
12101 2001-10-02 Akim Demaille <akim@epita.fr>

12104 instead of exec'ing to preserve $0 and $@.
12106 2001-10-01 Akim Demaille <akim@epita.fr>
12108 * tests/testsuite (AT_INIT) <at_pass_list>: New.
12109 Don't run twice the same test.

12127 * lib/autoconf/status.m4 (AC_OUTPUT_MAKE_DEFS):
12128 Don't use nested parenthesization. This patch was originally
12129 suggested to bug-autoconf by Philippe De Muyter on 2000-05-28,
12130 but somehow it didn't get incorporated then.
12131 * doc/autoconf.texi (Limitations of Usual Tools):
12132 Clarify remark about sed and nested parenthesization.
12134 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF):
12135 Report an error if the size cannot be determined even though
12136 the type exists.
12137 * lib/autoconf/general.m4 (_AC_COMPUTE_INT_COMPILE):
12138 Check for `expr' arithmetic overflow, and for compilation failure,
12139 and invoke a new argument $4 if either is discovered.
12140 This makes _AC_COMPUTE_INT_COMPILE more like _AC_COMPUTE_INT_RUN.
12141 (_AC_COMPUTE_INT): Pass IF-FAILS arg to _AC_COMPUTE_INT_COMPILE.
12143 2001-09-28 Akim Demaille <akim@epita.fr>

12151 * lib/autotest/general.m4 (AT_VICTIMS): Rename as...
12152 (AT_TESTED): this.

12154 Output `AT_tested' only when existing.
12155 Catch unexpanded PACKAGE_STRING and PACKAGE_BUGREPORT.
12157 2001-09-27 Akim Demaille <akim@epita.fr>
12159 Fix the passing of $? to ACTION-IF-FAILED in AC_TRY_RUN, that
12160 generates too many bug reports.
12162 * lib/autoconf/general.m4 (_AC_RUN_IFELSE): Pass the right exit
12163 status when executing the ACTION-IF-FALSE.
12164 * tests/base.at (AC_TRY_*): Rename as...

12171 * tests/c.at (Extensions, C keywords)
12172 (Broken/missing compilers, AC_PROG_CPP with warnings)
12173 (AC_PROG_CPP without warnings, AC_PROG_CPP via CC)
12174 (AC_PROG_CPP requires AC_PROG_CC): here and...
12175 * tests/fortran.at (GNU Fortran 77): there.
12176 * doc/autoconf.texi (autoconf Invocation): Fix the example:
12177 AC_TRY_RUN is about compilation, not shell commands.
12178 (Test Programs): AC_TRY_RUN works as used to be advertised.
12180 2001-09-27 Akim Demaille <akim@epita.fr>
12182 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Fix bugs spotted by
12183 Raja R Harinath:
12184 Be sure to detect when $LINENO always returns the same value.
12185 Look for the original script, basename($0) is certainly not
12186 enough.
12187 Pass the CLI arguments to `$as_me.lineno'.
12189 2001-09-25 Akim Demaille <akim@epita.fr>
12191 * lib/autotest/general.m4 (AT_INIT): Dump the whole config.log.

12199 of --language now.
12201 2001-09-23 Akim Demaille <akim@epita.fr>
12203 * doc/autoconf.texi (Top): Wrap in @ifnottex.
12205 2001-09-23 Akim Demaille <akim@epita.fr>
12207 * lib/autoconf/status.m4 (_AC_SRCPATHS): Compute and provide
12208 ac_buildpath, ac_top_buildpath, ac_srcpath, and ac_top_srcpath.
12209 (_AC_OUTPUT_FILES): Also substitute srcpath, top_srcpath,
12210 builddir, buildpath, top_builddir, and top_buildpath.
12211 (_AC_OUTPUT_SUBDIRS): Compute the dir variables *before* changing
12212 the current directory.
12213 * lib/autoconf/general.m4 (_AC_INIT_HELP): Compute the dir
12214 variables *before* changing the current directory.

12217 variables.
12219 * lib/autotest/general.m4: Do not reset AT_victims.
12220 Don't compute at_srcdir nor at_top_srcdir.
12222 * tests/tools.at: Hence use top_srcdir.
12224 * tests/Makefile.am, tests/autoconf, tests/autoheader,
12225 * tests/autom4te, tests/autoreconf, tests/autoupdate, tests/ifnames:
12226 Remove.
12227 * tests/autoreconf.in, tests/wrappl.in, tests/autom4te.in,
12228 * tests/wrapsh.in, tests/autoupdate.in: New.
12229 * tests/Makefile.am (DISTCLEANFILES, EXTRA_DIST): Adjust.
12230 * configure.ac: Build the position independent wrappers.
12232 * man/Makefile.am: Now that test wrappers are position
12233 independent, use them and drop dark envvar magic.
12235 2001-09-23 Akim Demaille <akim@epita.fr>
12237 * doc/autoconf.texi (Common Shell Constructs): Rename as...
12238 (Programming in M4sh): this.
12239 Promote to @section.

12256 over-escaping.

12266 (Autoconf): Adjust.
12268 2001-09-23 Tim Van Holder <tim.van.holder@pandora.be>
12270 * m4/auxdir.m4, m4/cond.m4, m4/depend.m4, m4/init.m4,

12279 2001-09-22 Akim Demaille <akim@epita.fr>
12281 * lib/autoconf/autotest.m4: Create `package.m4'.
12282 * tests/Makefile.am (package.m4): Remove.
12284 2001-09-22 Akim Demaille <akim@epita.fr>
12286 Rely on `$LINENO' when possible instead of `__oline__'.
12288 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Provide some form of
12289 `$LINENO' support replacement when not supported.
12290 (_AS_CR_PREPARE, _AS_TR_CPP_PREPARE, _AS_TR_SH_PREPARE): Invoke
12291 them explicitly to be sure they are not output before this section
12292 (via m4_require). Cosmetic only.
12293 * lib/autoconf/c.m4, lib/autoconf/general.m4,
12294 * lib/autoconf/programs.m4: Replace all the occurrences of
12295 `__oline__' with `$LINENO'.
12296 * doc/autoconf.texi (Special Shell Variables): Document LINENO.
12298 2001-09-21 Tim Van Holder <tim.van.holder@pandora.be>
12300 * lib/autoconf/functions.m4 (_AC_FUNC_FORK): Replaceded an 8-bit
12301 character (u: -> ue) in a code comment.
12302 (AC_FUNC_LSTAT_FOLLOWS_SLASHED_SYMLINK): Only run 'ln -s' if we know
12303 it works.
12305 2001-09-21 Akim Demaille <akim@epita.fr>
12307 * Makefile.maint (AUTOM4TE): Neutralize autom4te.
12308 Suggested by Jim Meyering.
12310 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
12312 * lib/autoconf/programs.m4: Use extensions listed in
12313 $ac_executable_extensions when looking for programs.
12315 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
12317 * lib/autoconf/general.m4: Fix a small Englisho.
12318 * lib/autoconf/status.m4: Fix a small typo. Handle DOS paths when
12319 setting up ac_dir_suffix and ac_top_builddir.
12320 * lib/m4sugar/m4sh.m4: Default CDPATH to $PATH_SEPARATOR, not ':'.
12322 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
12324 * doc/autoconf.texi (File System Conventions): Clarify the use of
12325 PATH_SEPARATOR.
12326 (Special Shell Variables[PATH_SEPARATOR]): Ditto.
12327 (Special Shell Variables[CDPATH]): Mention that $PATH_SEPRATOR should
12328 be used instead of ':'.
12329 * lib/autotest/general.m4: Replace occurrences of ':' in
12330 AUTOTEST_PATH with $PATH_SEPARATOR at test suite startup.
12332 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
12334 * tests/atgeneral.m4: Add basic support for test ranges (e.g. 7-34) as
12335 arguments. Fixed a typo.
12337 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
12339 * man/Makefile.am (.x.1): Use @PATH_SEPARATOR@, not ':' to set up
12340 $PATH. Also set AUTOM4TE_CFG, so we can process autom4te properly.
12342 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
12344 * bin/autoscan.in: Add 'exec-perl-if-not-run-by-perl'.
12345 * bin/autoupdate.in: Ditto.
12346 * bin/autoheader.in: Reworded a few comments.
12347 * bin/autoconf.in: Reworded help text for a few options.
12348 * bin/autoheader.in, bin/autom4te.in, bin/autoreconf.in,
12349 * bin/autoscan.in, bin/autoupdate.in: Ditto.
12351 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
12353 * lib/Autom4te/XFile.pm (open): Simplified the error message (we
12354 already have $file). Set output files to binary mode (helps avoid
12355 CR issues on DOSish systems).
12357 2001-09-19 Akim Demaille <akim@epita.fr>
12359 * lib/autotest/general.m4: Englishoes.
12360 From Tim Van Holder and Alexey Mahotkin.
12362 2001-09-18 Paul Eggert <eggert@twinsun.com>
12364 * doc/autoconf.texi (Common Shell Constructs): New node,
12365 documenting AS_DIRNAME.
12366 (Limitations of Usual Tools): Refer to it when discussing dirname.
12367 Also, update discussion of POSIX standard to reflect latest draft.
12369 * lib/autoconf/c.m4:
12370 (AC_LANG_INT_SAVE(C)): Also support negative values, down to LONG_MIN.
12372 * lib/autoconf/general.m4 (_AC_COMPUTE_INT_COMPILE):
12373 Do not pass a first argument with leading '-'
12374 to expr, by parenthesizing initial integers that might be negative.
12376 * doc/autoconf.texi (Particular Functions): AC_FUNC_GETPGRP
12377 now merely checks whether it is an error to pass an argument
12378 to getpgrp.
12380 * lib/autoconf/functions.m4 (_AC_FUNC_GETPGRP_TEST): Remove.
12381 (AC_FUNC_GETPGRP): Don't bother with a runtime test. Just check
12382 whether it is a (compile-time) error to pass an argument to
12383 getpgrp. This simpler test supports the revised documentation,
12384 and is all that AC_FUNC_GETPGRP's users really need.
12386 2001-09-18 Akim Demaille <akim@epita.fr>
12388 * doc/autoconf.texi (Limitations of Make) <$<>: New.
12390 2001-09-18 Akim Demaille <akim@epita.fr>
12392 * doc/autoconf.texi (Limitations of Usual Tools) <find>: More about
12393 `{}'.
12394 * lib/autotest/general.m4 (AT_INIT): Adjust.
12396 2001-09-18 Paul Wagland <paul@wagland.net>
12398 * tests/m4sh.at: Ensure that AS_DIRNAME handles '/', '//' and '///'
12399 correctly.
12400 Add test for AS_BASENAME.
12401 * lib/m4sugar/m4sh.m4: Fix AS_BASENAME so that it passes the previous
12402 added test. It now correctly handles /1/2/3/, returning '3' not ''.
12403 Added AS_BASENAME_SED to make the interface the same as AS_DIRNAME.
12404 * tests/base.at: Fixed the expected responses. The old ones were
12405 one line out...
12406 * lib/autoconf/general.m4: Fixed AC_PREFIX_PROGRAM, it now behaves as
12407 the documentation claims it should (and how it behaved in 2.13).
12409 2001-09-18 Akim Demaille <akim@epita.fr>
12411 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): No INIT-CMDS in
12412 the AC_CONFIG_COMMANDS invocation.
12413 This also solves the name clash problems.
12414 Don't set the package's ID.
12415 * lib/m4sugar/Makefile.am (version.m4): Revamp.
12416 No longer to be shipped.
12417 (version.in): Remove.
12418 * lib/m4sugar/m4sugar.m4, lib/autoconf/general.m4,
12419 * lib/autoconf/status.m4: Adjust.
12420 Use `m4_PACKAGE_STRING'.
12421 * lib/autotest/general.m4 (AT_INIT): N-th signature change: now
12422 the only optional argument is the name of the test suite.
12423 Expect `package.m4' to define the package signature.
12424 * lib/autom4te.in (Autotest): Add `package.m4?'.
12425 * tests/Makefile.am (package.m4): New.
12426 * tests/suite.at: ifnames is a victim.
12428 2001-09-18 Akim Demaille <akim@epita.fr>
12430 * lib/autom4te.in (Autoconf): Preselect AM_CONDITIONAL,
12431 AC_LIBSOURCE, AC_CONFIG_FILES.
12432 * lib/autotest/general.m4 (AT_INIT): Don't abort when a tested
12433 program version string doesn't match the package's.
12434 * lib/autoconf/general.m4 (AC_CACHE_VAL): Reestablish the space
12435 after `(cached)'.
12437 2001-09-17 Paul Eggert <eggert@twinsun.com>
12439 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):
12440 Allow expression to return any value that can fit into unsigned long
12441 (not int, as before). Check for output errors.
12443 2001-09-17 Bruno Haible <haible@ilog.fr>
12445 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):
12446 Always include <stdio.h> and <stdlib.h>. Evaluate
12447 the expression in an extra function before these includes. Call
12448 fprintf "%d" only after ensuring the argument is of type 'int'.
12449 Reported by Wayne Chapeskie <waynec@spinnaker.com>.
12451 2001-09-17 Paul Eggert <eggert@twinsun.com>
12453 Fix bug reported by Paul Townsend on AIX 4.3.3.0 with CFLAGS=-O4
12454 or CFLAGS=-O5. In that case, the linker has a relaxed view of
12455 fatal errors, and AC_CHECK_LIB causes it to include libraries even
12456 when they don't exist.
12458 * lib/autoconf/headers.m4 (AC_HEADER_DIRENT): Use AC_SEARCH_LIBS,
12459 not AC_CHECK_LIB, so that we don't use -ldir or -lx if we don't
12460 need it.
12462 * lib/autoconf/specific.m4 (AC_ISC_POSIX): Replace the old, crufty
12463 version with the version used by fileutils 4.1, except use
12464 AC_SEARCH_LIBS, not AC_CHECK_LIB, so that we don't use -lcposix if
12465 we don't need it.
12467 * doc/autoconf.texi (AC_ISC_POSIX): Describe new behavior.
12469 2001-09-13 Akim Demaille <akim@epita.fr>
12471 * tests/base.at, tests/m4sh.at: Be sure to issue the bangshe line
12472 _first_.
12473 Reported by Gerrit P. Haase.
12475 2001-09-13 Akim Demaille <akim@epita.fr>

12509 * lib/autotest/general.m4 (AT_INIT): Create and remove
12510 `$as_me.[0-9]+' instead of `debug-[0-9]+.sh', so that multiple

12624 the maintainer is dumb enough to do that...
12626 * lib/autotest/general.m4 (AT_SETUP, AT_LINE): Demonstrates your
12627 excellence in M4 quotation: consider `__file__' is active.
12629 And BTW, when invoking m4, pass the --include in the right order:
12630 the wrong one.
12632 * bin/autom4te.in, bin/autoupdate.in: Use reverse when kingtal to
12633 4m.

12660 New, extracted from main.
12661 Use IO::File wherever possible.
12662 (input.m4): Be constant, use -I instead of hard coding $tmp.

12664 Don't invoke `_au_disable', since ac was not loaded, but just

12667 2001-08-31 Akim Demaille <akim@epita.fr>
12669 Version 2.52d.

12694 * doc/autoconf.texi (Quadrigraphs): Document `@&t@'.
12695 (testsuite Scripts): There is no such thing as `atconfig.in'.
12696 And actually one diagram is missing: test suite runtime.
12698 2001-08-31 Akim Demaille <akim@epita.fr>
12700 * lib/Autom4te/General.pm (&find_file): Browse the includes in the
12701 inverse order.
12703 2001-08-31 Akim Demaille <akim@epita.fr>
12705 * bin/autoupdate.in (@include): `installcheck' revealed the path
12706 to m4sugar was lacking!
12708 2001-08-31 Akim Demaille <akim@epita.fr>
12710 * man/Makefile.am (.x.1): We really have to pass
12711 autom4te_perllibdir.
12713 2001-08-31 Akim Demaille <akim@epita.fr>
12715 * lib/autotest/general.m4 (AT_INIT): Don't pass all the args to

12721 * bin/autom4te.in (&parse_args): Strip `.' from `@include'.
12722 * bin/autoupdate.in: Use --include, -I, and --force, -f, too.

12748 * tests/tools.at (Syntax of the Perl scripts): Pass the lib dir.
12749 (autoheader): Pass --force since the test suite goes too fast for
12750 the time stamps.
12751 Adjust to the new autoheader messages.
12753 2001-08-31 Akim Demaille <akim@epita.fr>

12767 `autoheader: `config.hin' is created'.
12768 * tests/tools.at (Syntax of the Perl scripts): Check autoheader.
12770 2001-08-31 Akim Demaille <akim@epita.fr>
12772 * bin/autoheader.in: Rewrite in Perl.

12778 Map --localdir, --autoconf-dir onto it.
12779 Forward autom4te's options instead of interpreting them.
12780 * bin/autoconf.in, bin/autoheader.in (AC_MACRODIR, autoconf_dir):
12781 There is no such envvar since the inception of autom4te.cfg.
12782 * bin/autom4te.in (&parse_args): Uniquify `@include'.

12790 * bin/autom4te.in (&find_file): Support `FILE?' standing for
12791 optionally `FILE'.

12794 * lib/autom4te.in (Autoconf): Add `acsite.m4?' and `aclocal.m4?'.
12796 2001-08-31 Akim Demaille <akim@epita.fr>
12798 * configure.ac: Also find tested executables in bin.
12799 * bin/autoconf.in, bin/autoheader.in, bin/autoreconf.in,

12803 * lib/Autom4te/General.pm (&find_peer): Remove.
12804 * lib/autotest/general.m4 (AT_INIT): `AUTOTEST_PATH=a:b' gives
12805 `abuild:asrc:bbuild:bsrc', not `abuild:bbuild:asrc:bsrc'.
12806 * man/Makefile.am: Let help2man rely on PATH instead of trying to
12807 find the executables for it.
12808 * tests/Makefile.am: Major cleanup. Too lazy to document...
12809 * tests/atlocal.in: Remove all the obscure envvar manipulations.
12810 We only need PERL.
12811 * tests/atspecific.m4, tests/tools.at: Passing --localdir is
12812 indeed related to running the test suite, while passing
12813 --autoconf-dir and others is related to running non installed
12814 Autoconf executables. So don't do that, leave it to...
12815 * tests/autoconf, tests/autoheader, tests/autom4te, tests/autoupdate,
12816 * tests/autoscan: New.
12817 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): Don't
12818 refer to library files: rely on --language.

12822 * bin/autom4te.in, lib/autom4te.in, bin/autoconf.in:

12833 * bin/autom4te.in (&handle_output): s/@__@/@&t@/.
12834 Suggested by Paul Eggert.
12836 2001-08-29 Akim Demaille <akim@epita.fr>
12838 * Makefile.maint (do-po-update): Wget refuses to overwrite files:
12839 download in a tmp dir.
12841 2001-08-29 Akim Demaille <akim@epita.fr>
12843 * lib/autotest/general.m4: s/AT-devnull/devnull/ since there are

12904 * lib/autotest/general.m4 (AT_INIT): Log the command line.

13374 * tests/mktests.sh: Update year in copyright notice.
13376 2001-08-12 Alexandre Duret-Lutz <duret_g@epita.fr>
13378 * tests/semantics.at (AC_C_BIGENDIAN): New test.
13380 2001-08-11 Alexandre Duret-Lutz <duret_g@epita.fr>
13382 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Handle ACTION-IF-TRUE,
13383 ACTION-IF-FALSE, and ACTION-IF-UNKNOWN.
13384 * doc/autoconf.texi (C Compiler Characteristics): Update
13385 documentation for AC_C_BIGENDIAN.
13387 2001-08-11 Alexandre Duret-Lutz <duret_g@epita.fr>
13389 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Guess endianness by grep'ing
13390 magic values from an object file when cross-compiling.
13391 Based on code by Guido Draheim <Guido.Draheim@gmx.de>.
13393 2001-08-10 Akim Demaille <akim@epita.fr>
13395 * bin/autom4te.in (&handle_output): Don't use `grep' with side
13396 effects.
13397 Suggested by Russ Allbery.
13399 2001-08-10 Ralf Corsepius <corsepiu@faw.uni-ulm.de>
13401 * lib/autoconf/general.m4 (_AC_OUTPUT_SUBDIRS): Propagate the
13402 current $prefix to the sub-configures.
13404 2001-08-09 Tim Van Holder <tim.van.holder@pandora.be>
13406 * lib/autoconf/lang.m4: Ignore *.xSYM when looking for an executable
13407 extension (needed on BeOS). Reported by Guido van Rossum.
13409 2001-08-09 Akim Demaille <akim@epita.fr>
13411 * bin/autom4te.in ($icache): Load it only if older than autom4te.
13413 2001-08-07 Akim Demaille <akim@epita.fr>
13415 * lib/autotest/general.m4 (AT_INIT): All the `at-*' are to be
13416 removed.
13417 (at-setup-line): Huh? Be a variable `at_setup_line', not a file.
13418 No need to remove the files before and after the each test, before
13419 each test and at the end of the suite is enough.
13420 Display only the children `times', not the shell's.
13421 If the test failed or was skipped, at-times is not available.
13423 2001-08-07 Akim Demaille <akim@epita.fr>
13425 Always produce testsuite.log, including when there are no
13426 failures. This helps getting information on skipped tests, and
13427 duration of the tests. Err, implement the latter btw.
13429 * lib/autotest/general.m4 (AT_INIT): Set up fd 6 for the log.
13430 Dump information on the first run of each test.
13431 (AT_CLEANUP): Create `at-times' containing the duration of the
13432 test group.
13434 2001-08-07 Akim Demaille <akim@epita.fr>
13436 The use of `dumpstat' revealed that `len' was used although it
13437 should not. m4_text_wrap was using it, but in the Autoconf world
13438 where it is legal. Hence (i) test M4sh in its own world, not
13439 Autoconf's, and (ii), ahem, fix the bug :)
13441 * lib/autotest/general.m4: Be sure the set good quotes, as tracing
13442 does not like `' instead of [].
13443 (AT_INIT): Forbid `^_?AT_'.
13444 And don't output such tokens.
13445 * tests/Makefile.am (CLEANFILES): Add `script', `script.s4g',
13446 `script.as', and `autom4te.cache'.
13447 Remove `empty' and `macro' which are no longer used.
13448 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): New.
13449 * tests/m4sugar.at: Use it.
13450 * lib/m4sugar/m4sugar.m4: Use `m4_len' not `len'.
13452 2001-08-07 Akim Demaille <akim@epita.fr>
13454 * bin/autoconf.in, bin/autoheader.in: --force, -f is a new option.
13456 2001-08-07 Alexandre Duret-Lutz <duret_g@epita.fr>
13458 * bin/autom4te.in (handle_output): Typo in quadrigraph substitution.
13460 2001-08-04 Akim Demaille <akim@epita.fr>
13462 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA, AC_FUNC_ERROR_AT_LINE)
13463 (AC_FUNC_FSEEKO, AC_FUNC_OBSTACK): Use AC_LANG_IFELSE, not
13464 AC_TRY_LINK.
13465 * lib/autoconf/headers.m4 (AC_HEADER_MAJOR): Likewise.
13466 * lib/autoconf/fortran.m4 (_AC_LANG_PROGRAM_C_F77_HOOKS)
13467 (AC_F77_MAIN): Likewise.
13469 2001-08-04 Akim Demaille <akim@epita.fr>
13471 Don't rely on M4sugar outputting the patterns in files, since we
13472 might process the output _without_ running m4, hence without these
13473 files.
13475 * lib/m4sugar/m4sugar.m4 (m4_init): No need for `m4_tmpdir'.
13476 * bin/autom4te.in (@Request::includes): Remove, unused.
13477 (@Request::source): Rename as...
13478 (@Request::input): this.
13479 (@preselect): Add `m4_pattern_forbid' and `m4_pattern_allow'.
13480 (&handle_output): Fetch the patterns from the traces.
13481 `$forbidden' and `$allowed' are constant: use m//o.
13482 (&handle_m4): M4sugar no longer wants `m4_tmpdir'.
13483 (m4_pattern_forbid, m4_pattern_allow): Adjust for tracing only.
13485 2001-08-04 Akim Demaille <akim@epita.fr>
13487 `autoconf && autoheader' is sped up. Now, speed up `autoheader &&
13488 autoconf', i.e., in addition to caching traces, cache the output.
13490 * bin/autom4te.in (Request::cache): Rename as...
13491 (Request::id): this.
13492 ($cache, $icache, $tcache, $ocache): New.
13493 (&handle_m4): Save M4 output in the cache instead of $tmp.
13494 (&handle_output): Adjust.
13495 (&up_to_date_p): Check that the output cache is up to date too.
13496 (top level): Run `&handle_m4' iff force or the cache is invalid.
13497 Run `&handle_output' if the output cache is more recent.
13499 2001-08-04 Akim Demaille <akim@epita.fr>
13501 * bin/autom4te.in ($force): New.
13502 (&parse_args, &print_usage): -f, --force is a new option.
13503 (&handle_output): CPP directives might have spaces after `#'.
13504 (&parse_args): The first file only can be frozen.
13506 2001-08-04 Akim Demaille <akim@epita.fr>
13508 Don't let autom4te compute the `include' traces several times:
13509 first check that the trace cache file is up to date, and then
13510 compare its timestamp with that of the output.
13512 * bin/autom4te.in, bin/autoupdate.in, bin/autoscan.in: Normalize
13513 the preamble. Don't require 5.005 as Autom4te::General does it,
13514 and better yet (use `use', not `require'!).
13515 * lib/Autom4te/Struct.pm: Rename the last occurrences of
13516 Class::Struct as Autom4te::Struct.
13517 * lib/Autom4te/General.pm (File::stat): Use it.
13518 (&mtime): New, export it.
13519 * bin/autom4te.in: Use it.
13520 Declare `$req' is invalid if it is outdated.
13521 Don't declare it valid before saving it if something went wrong.
13523 2001-08-04 Akim Demaille <akim@epita.fr>
13525 Autom4te shall not encode Autoconf data, and preselecting traces
13526 must be proposed to the users.
13528 * bin/autom4te.in (@required_trace): Remove.
13529 (@preselect): New.
13530 (&parse_args, &print_usage): -p, --preselect is a new option.
13531 (&up_to_date_p): Adjust.
13532 * bin/autoconf.in: Preselect some Autoconf macros.
13534 2001-08-04 Akim Demaille <akim@epita.fr>
13536 * tests/tools.at (autoconf --trace: user macros): Check traces on
13537 macros invoked without arguments, and macros invoked with multiple
13538 lines arguments.
13540 2001-08-03 Alexandre Duret-Lutz <duret_g@epita.fr>
13542 * bin/autom4te.in (handle_traces): Fix rewriting of traces without
13543 arguments.
13545 2001-08-03 Akim Demaille <akim@epita.fr>
13547 * bin/autoconf.in ($@): Work around the usual sh bug.
13548 From Nicolas Joly.
13550 2001-08-03 Akim Demaille <akim@epita.fr>
13552 Clean up the handling of the M4 builtins tracing exception.
13554 * bin/autom4te.in (Request::request): Don't complete M4 builtins
13555 trace requests.
13556 (@m4_builtins): Rename as...
13557 (@m4_builtin): this.
13558 (%m4_builtin_alternate_name): New.
13559 (&parse_args): Complete the trace requests with alternate names.
13560 (&handle_traces): Hence no longer do it here.
13561 (&trace_requests): Remove, unused.

13565 * doc/autoconf.texi (Redefined M4 Macros): Document m4_exit,
13566 m4_if, and m4_wrap.

13570 * lib/m4sugar/m4sugar.m4 (m4_init): Also forbid `_m4_*' tokens.
13571 (m4_divert_pop): Dump the whole diversion stack when a diversion
13572 mismatch happens.
13573 * bin/autom4te.in (&handle_output): Remember of the first
13574 occurrence of a possibly undefined macro, not the last.
13575 Complain about the possibly undefined macros in the same order as
13576 the appear in the output.
13577 * lib/autoconf/Makefile.am (autoconf.m4f): List its dependencies.
13578 * tests/tools.at (autoconf: forbidden tokens, basic)
13579 (autoconf: forbidden tokens, exceptions): No longer sort
13580 autoconf's stderr, as it is now deterministic.
13581 Check that `dnl' is caught.
13583 2001-08-01 Akim Demaille <akim@epita.fr>
13585 * configure.ac: Bump to 2.52c.

13820 The runtime test for AC_FUNC_GETPGRP fails when prototypes are
13821 used. Well, then use the prototypes when you can, and runtime as
13822 a last resort.

14034 dummy alternate main is required even if the user provides her own
14035 'main'.

14037 provide an alternate 'main' function name, using the 'main' from
14038 the Fortran libraries.
14039 (AC_LANG_PROGRAM(C)): Use F77_DUMMY_MAIN, if it is defined, so that
14040 cross-language link tests can be performed successfully.
14041 (_AC_F77_NAME_MANGLING): Require AC_F77_DUMMY_MAIN. Also put $FLIBS
14042 after $LIBS, for consistency; this should be the general rule since

14048 * atgeneral.m4 (AT_CHECK): Add a newline to the end of
14049 at-stdout and at-stderr instead of removing the newline
14050 from the echo output, which is not guaranteed to work.
