92 Make inter-release --version output more useful.
94 Now, each unofficial build has a version "number" like 2.61a-19-58dd,
95 which indicates that it is built using the 19th change set

182 Fix config header generation with AIX awk.
183 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS_PREPARE): In awk
184 script, use helper array D_is_set, as `" 0"' does not evaluate

1365 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't look

1385 for C++; this drops support for anonymous struct and union types,
1386 which were problematic anyway.

1405 with objects too. Document the restrictions on its use.
1406 Document the restrictions on AC_CHECK_ALIGNOF's type argument.
1407 * lib/autoconf/types.m4 (_AC_CHECK_TYPE_NEW):
1408 For C, just try sizeof (TYPE) and sizeof ((TYPE)); if the former
1409 works but the latter doesn't, then it's a valid type.
1410 This lets people use function types and so forth.
1411 For C++ there doesn't seem to be a simple solution, so leave it alone.
1412 (AC_CHECK_SIZEOF): Allow argument to be a variable.
1413 (AC_CHECK_SIZEOF, AC_CHECK_ALIGNOF): Don't bother to invoke
1414 AC_CHECK_TYPE; that wasn't documented or necessary.

1467 nonstandard grep R.E. escape sequences.
1469 2007-03-17 Jim Meyering <jim@meyering.net>
1471 * doc/autoconf.texi: Adjust grammar around use of "heuristics".
1472 (Limitations of Usual Tools): Also list \< and \>, and mention that
1473 HP-UX's grep, like the one from Solaris, does not support that syntax.
1475 2007-03-09 Stepan Kasal <kasal@ucw.cz>
1477 * doc/autoconf.texi (Specifying Names): `--host' does not
1478 change the build type.
1480 2007-03-05 Paul Eggert <eggert@cs.ucla.edu>
1482 * doc/autoconf.texi (C Compiler): Warn that AC_C_BIGENDIAN
1483 suggests AC_CONFIG_HEADERS.
1484 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Warn if not using
1485 AC_CONFIG_HEADERS. Problem reported by
1486 Peter O'Gorman.

1493 * tests/semantics.at (AC_C_BIGENDIAN): Don't reject hosts that have
1494 universal binaries. Problem reported by Elias Pipping.
1496 2007-02-27 Paul Eggert <eggert@cs.ucla.edu>
1498 * NEWS: AC_C_BIGENDIAN now supports universal binaries a la Mac OS X.

1502 Add support for Solaris-style _LITTLE_ENDIAN and _BIG_ENDIAN.
1503 Reindent for sanity's sake.
1505 2007-02-24 Eric Blake <ebb9@byu.net>
1507 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Update
1508 copyright.
1509 * lib/autoconf/general.m4 (_AC_INIT_COPYRIGHT): Likewise.
1510 * lib/autotest/general.m4 (AT_INIT): Likewise.
1511 (_AT_DECIDE_TRACEABLE): Fix syntax highlighting.
1513 2007-02-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1515 * lib/autotest/general.m4 (AT_INIT): With --clean, return exit
1516 status of rm so we know when it failed.
1517 If cleaning of test dir failed before running the test, warn.
1518 Output the line separator in verbose mode before the warning
1519 to make clear the warning belongs to the following test.
1521 2007-02-08 Paul Eggert <eggert@cs.ucla.edu>
1523 * doc/autoconf.texi (Parentheses): Mention problem with (( in
1524 shells.

1530 errors introduced in last change.
1532 2007-02-07 Paul Eggert <eggert@cs.ucla.edu>
1534 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Prefer \r to
1535 an actual carriage return. Use "ac_cr" to contain the actual
1536 carriage return.
1537 * doc/autoconf.texi (Limitations of Usual Tools): Document problem
1538 with traditional Awk and begin.
1539 * tests/torture.at (Limitations of Builtins): Document the problem
1540 with Bash 2.03 printf.
1541 (Substitute and define special characters):
1542 Remove trailing white space. Work around a bug in Solaris 8 /bin/bash.
1544 2007-02-06 Ralf Menzel <menzel@ls6.cs.uni-dortmund.de> (tiny change)
1546 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Redirect
1547 input from /dev/null in awk test, so even Solaris /usr/bin/awk
1548 will not wait for input with a script containing only a BEGIN
1549 rule.
1551 2007-02-03 Paul Eggert <eggert@cs.ucla.edu>
1553 * doc/autoconf.texi (Introduction, Why GNU M4): Clarify M4 version

1573 2007-01-28 Paul Eggert <eggert@cs.ucla.edu>
1575 * doc/autoconf.texi (Shellology): pdksh 5.2.14 is still the
1576 latest version.
1577 (Shell Substitutions): Note problems with @{var:=value} etc.
1578 Add a new section for problems with @{#var} etc. Problem noted
1579 by Ralf Wildenhues. See:

1582 2007-01-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1584 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Also
1585 AC_SUBST([MKDIR_P]), so that Automake < 1.10 will pick up its
1586 trace, if a package uses AC_PROG_MKDIR_P explicitly. The actual
1587 substitution will still be done by the special code.
1588 Report by Jim Meyering.
1590 * doc/autoconf.texi (File System Conventions): Mention that
1591 $PATH_SEPARATOR is for the build system only.

1602 Test all 8 bit non-NUL characters.
1603 Report against Automake by Patrick Welche.
1605 2007-01-15 Stepan Kasal <kasal@ucw.cz>
1607 * doc/autoconf.texi: Direntry for "autoconf Invocation" renamed.
1609 2007-01-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1611 * lib/autoconf/programs.m4 (AC_PROG_SED): When closing a pipe
1612 early on the reader side, drop stderr of the input to avoid
1613 `broken pipe' error output; this may happen even with shell
1614 builtin `echo' of some bash versions. Reports by Ian Macdonald
1615 <iamacdo@telkomsa.net> and Sam Sexton <Sam.Sexton@reuters.com>.
1617 2007-01-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1619 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Use newlines to
1620 separate items of `ac_user_opts', to avoid long lines.
1621 (_AC_INIT_PARSE_ENABLE2, _AC_ENABLE_IF_ACTION): Adjust.
1623 2007-01-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1625 * doc/autoconf.texi: Fix some typos.
1627 2007-01-05 Paul Eggert <eggert@cs.ucla.edu>
1629 Fix some wording problems noted by Paolo Bonzini in:
1630 http://lists.gnu.org/archive/html/autoconf-patches/2007-01/msg00077.html
1631 * doc/autoconf.texi (Signed Overflow Examples): Give more
1632 discussion about the allow_superuser_privileges example,
1633 and change it a bit to make things clearer.
1634 (Optimization and Wraparound): Clarify whether the compiler
1635 will generate an infinite loop for the example derived from
1636 Autoconf's mktime test.
1637 (Signed Overflow Advice): Say that -ftrapv is meant for debugging.
1638 Also, clarify unsigned multiplication overflow.
1640 2007-01-04 Eric Blake <ebb9@byu.net>
1642 * bin/Makefile.am (RELEASE_YEAR): New macro.
1643 (edit): Use it to supply correct copyright year to scripts.
1644 * bin/autoconf.as (version): Use it.
1645 * bin/autoheader.in ($version): Likewise.
1646 * bin/autom4te.in ($version): Likewise.
1647 * bin/autoreconf.in ($version): Likewise.
1648 * bin/autoscan.in ($version): Likewise.
1649 * bin/autoupdate.in ($version): Likewise.
1650 * bin/ifnames.in ($version): Likewise.
1652 2007-01-02 Paul Eggert <eggert@cs.ucla.edu>
1654 * doc/autoconf.texi (Integer Overflow): Revised based on today's
1655 feedback. The most important changes document what happens when
1656 you convert an out-of-range value to a signed integer type, and
1657 say that (sum < a) != (b < 0) reliably detects overflow when sum =
1658 a + b.
1660 * doc/autoconf.texi (Integer Overflow): Greatly expand and
1661 rewrite, taking notions from the recent discussion on the gcc and
1662 autoconf mailing lists; please see
1663 http://lists.gnu.org/archive/html/autoconf-patches/2006-12/msg00091.html
1664 and follow the many links.
1665 (Integer Overflow Basics, Signed Overflow Examples):
1666 (Optimization and Wraparound, Signed Overflow Advice):
1667 (Signed Integer Division): New sections.
1669 2006-12-28 Steven G. Johnson <stevenj@alum.mit.edu>
1671 * lib/autoconf/general.m4 (AC_DEFINE_TRACE): Don't include
1672 preprocessor macro arguments in traced name.
1673 * doc/autoconf.texi (Defining symbols): Document longstanding
1674 support for AC_DEFINE-ing macros with arguments, and document
1675 behavior when the same variable has multiple AC_DEFINEs.
1676 * lib/autoconf/fortran.m4 (_AC_FC_WRAPPERS): Revert to the
1677 old implementation which AC_DEFINEs the FC_FUNC and FC_FUNC_
1678 macros directly, giving much shorter and simpler code.
1680 2006-12-28 Malcolm Purvis <malcolmp@xemacs.org> (trivial change)
1682 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Insert a
1683 space before "$ac_configure_args" to prevent a 'config.status
1684 --recheck' failure if ac_configure_args doesn't contain a leading
1685 space. This works around a problem with the XEmacs configure.ac,
1686 which uses the (undocumented) ac_configure_args variable
1687 inconsistently with Autoconf.
1689 2006-12-22 Paul Eggert <eggert@cs.ucla.edu>
1691 * lib/autoconf/functions.m4 (AC_FUNC_MKTIME):
1692 Include <limits.h>, and use its INT_MAX to rewrite the
1693 j loop so that it does not overflow 'int'. Problem reported by
1694 Ralf Wildenhues in
1695 <http://lists.gnu.org/archive/html/bug-gnulib/2006-12/msg00084.html>.
1696 Play it safe by shifting left by 1 rather than multiplying by 2,
1697 as GCC is less likely to optimize this away when the value
1698 is signed (when it assumes overflow leads to undefined behavior).
1699 Also, don't assume time_t uses two's complement.
1701 2006-12-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1703 * tests/torture.at (Substitute a 2000-byte string): Avoid using
1704 a 10kB long (multi-line) string literal, OpenServer 5.0.7 ksh
1705 dumps core on it. Report by Tim Rice.
1707 2006-12-18 Steven G. Johnson <stevenj@alum.mit.edu>
1709 * lib/autoconf/general.m4 (AC_ARG_ENABLE): Print help about
1710 --disable-option-checking to --help output even when
1711 AC_PRESERVE_HELP_ORDER is not used.
1712 (_AC_INIT_PARSE_ENABLE2): Print warnings using actual --enable or
1713 --with argument, rather than argument with [-.] replaced by
1714 underscores.
1715 * NEWS: Fix typo in previous change; the news was in the
1716 wrong section.
1718 2006-12-18 Paul Eggert <eggert@cs.ucla.edu>
1720 * NEWS: Warnings are now generated by default for unknown
1721 --enable-* and --with-* options.
1722 * doc/autoconf.texi (Option Checking): Renamed from
1723 (Configure Option Checking). Tighten up the wording a bit.
1724 (External Software, Package Options): Cross-reference to Option
1725 Checking, and use this to shorten our section.
1726 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Prefer test -n
1727 "$x" to test "x$foo" != x.
1728 * lib/autoconf/status.m4 (AC_OUTPUT): Likewise.
1729 Don't warn if $enable_option_checking is "no".
1730 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Initialize
1731 ac_unrecognized_opts to the empty string.
1732 Don't echo the unrecognized opts, as this might mishandle
1733 backslashes or leading -.
1734 (AC_PRESERVE_HELP_ORDER): Put the --disable-option-checking
1735 usage next to the other --disable-FEATURE options in the
1736 help string.
1738 2006-12-18 Steven G. Johnson <stevenj@alum.mit.edu>
1740 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS, _AC_INIT_PARSE_ARGS):
1741 (_AC_INIT_PARSE_ENABLE2, _AC_INIT_HELP, _AC_ENABLE_IF):
1742 Print warning for unrecognized --with and --enable options
1743 (AC_DISABLE_OPTION_CHECKING): New macro to disable warnings.
1744 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS, _AC_OUTPUT_SUBDIRS):
1745 Disable option checking when subdirs are configured.
1746 (AC_OUTPUT): If warnings are enabled, print warning about
1747 unrecognized --with and --enable options at the end of
1748 the configure output (as well as at the beginning).
1749 * doc/autoconf.texi (Option Checking): New node.
1750 Document new option warning functionality.
1752 2006-12-16 Eric Blake <ebb9@byu.net>
1754 * configure.ac (AC_INIT): Bump version, since 2.61a is released.
1755 * NEWS: Start news for current version.
1757 2006-12-15 Paul Eggert <eggert@cs.ucla.edu>
1759 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT):
1760 Define HAVE_GETMNTENT to 1, not to the empty string.
1761 Problem originally reported by Jochen Friedrich in
1762 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=403243>.
1764 This change prompted by a problem report by Andrey Simonenko in
1765 <http://lists.gnu.org/archive/html/bug-autoconf/2006-12/msg00026.html>.
1766 * doc/autoconf.texi (Defining Symbols): AC_DEFINE works for
1767 object-like macros only, in the traditional portable character
1768 set.
1769 * lib/autoconf/general.m4 (AC_DEFINE_TRACE_LITERAL):
1770 Warn about attempts to define things that are not identifiers.
1771 * lib/autoconf/fortran.m4 (_AC_FC_WRAPPERS): Rewrite to avoid
1772 awful hack that AC_DEFINEd macro names containing parentheses.
1774 2006-12-12 Paul Eggert <eggert@cs.ucla.edu>
1776 * doc/autoconf.texi: Undo some of the 2006-12-10 change. It was
1777 too drastic, even if Texinfo in theory requires it for info mode.
1779 (config.status Invocation): Renamed back from Recreating a
1780 Configuration).
1781 (Obsolete config.status Use): Renamed back from Obsolete Recreation.
1782 (Autoconf 2.13): Renamed back from 20th-century Autoconf 2.
1784 2006-12-11 Paul Eggert <eggert@cs.ucla.edu>
1786 * NEWS: Version 2.61a.
1788 2006-12-11 Paul Eggert <eggert@cs.ucla.edu>
1789 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1791 * NEWS: Document changes with echo and printf, and the lack
1792 of limits on the total size of multi-line values of substituted
1793 variables, and the AC_FUNC_FSEEKO fix.
1795 2006-12-10 Paul Eggert <eggert@cs.ucla.edu>
1797 * doc/autoconf.texi (Writing Autoconf Input): Renamed from
1798 Writing configure.ac.
1799 (Autoconf Input Layout): Renamed from configure.ac Layout.
1800 (Recreating a Configuration): Renamed from config.status Invocation.
1801 (Obsolete Recreation): Renamed from Obsolete config.status Use.
1802 (acconfig Header): Renamed from acconfig.h.
1803 (20th-century Autoconf 2): Renamed from Autoconf 2.13.
1804 (Writing Testsuites): Renamed from Writing testsuite.at.
1805 (Autom4te Cache): Renamed from autom4te.cache.
1807 * BUGS: Remove mention of VPATH problem, since it's now documented
1808 not to be a bug in the Autoconf build procedure itself, but rather
1809 a problem with the proprietary `make' programs.
1811 * doc/autoconf.texi (Build Directories): Add a cross reference
1812 to VPATH and Make.
1814 * build-aux/config.guess, build-aux/config.sub, build-aux/texinfo.tex:
1815 * doc/standards.texi: Sync from gnulib.
1817 * man/autoconf.1, man/autoheader.1, man/autom4te.1, man/autoreconf.1:
1818 * man/autoscan.1, man/autoupdate.1, man/config.guess.1:
1819 * man/config.sub.1, man/ifnames.1: Remove from CVS, since they're
1820 generated automatically.
1822 2006-12-06 Paul Eggert <eggert@cs.ucla.edu>
1824 * lib/autoconf/c.m4 (_AC_PROG_CC_C89): Also try -xc99=all, for Sun
1825 C 5.8 on Solaris 10. Using -xc99=all rather than -xc99 bypasses
1826 the buggy -xc99 option of Forte Developer 7 C on Solaris 9.
1828 2006-12-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1830 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Drop the
1831 `CEOF$ac_eof' special marker, the awk script cannot contain a
1832 line matching `^CEOF', so this is not needed any more.
1833 * tests/torture.at (Substitute a newline): Expose the `%!_!# '
1834 special marker in the test.
1836 2006-12-06 Stepan Kasal <kasal@ucw.cz>
1838 * tests/tools.at (autom4te preselections): Use `find -newer';
1839 remove one of the sleeps.
1841 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE): Make it
1842 more readable, using ...
1843 (_AC_INIT_PARSE_ENABLE2): ... this new helper macro.
1845 * doc/autoconf.texi (autoheader Invocation): Do not double-
1846 quote the parameter of `AH_BOTTOM' in the example.
1848 2006-12-05 Stepan Kasal <kasal@ucw.cz>
1850 * doc/autoconf.texi (Configuration Headers): Remove the
1851 example with multiple input files.
1852 (autoheader Invocation): Encourage `AH_BOTTOM', discouraging
1853 multiple input files.
1855 2006-12-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1857 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): When
1858 creating the awk substitution script, handle one input line at a
1859 time, so that the maximum length of a substituted (multi-line)
1860 value is not limited by the size of the sed pattern space.
1861 The trade-off is a slightly repetitive sed script.
1862 * doc/autoconf.texi (Limitations of Usual Tools): Branch labels
1863 can only have up to 7 characters, due to Solaris 10 /bin/sed.
1864 * tests/torture.at (Substitute a 2000-byte string): Increase the
1865 test with several long lines, they should not be caught by sed
1866 limits any more.
1868 * tests/tools.at (autom4te preselections): New test, to flag
1869 entries missing from autom4te.cfg.
1870 Report by David Byron <dbyron@hheld.com>.
1872 * tests/torture.at (Substitute a 2000-byte string): Actually use
1873 AC_PROG_AWK, so the last change works as intended.
1874 (Substitute and define special characters): Likewise.
1875 (Substitute a newline): Likewise.
1877 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Use `$AWK'
1878 instead of `awk' consistently.
1879 (_AC_OUTPUT_CONFIG_STATUS): Initialize $AWK.
1880 * tests/torture.at (Torturing config.status): Test both the
1881 result of AC_PROG_AWK and plain awk.
1882 (Substitute a 2000-byte string): Likewise.
1883 (Substitute and define special characters): Likewise.
1884 (Substitute a newline): Likewise.
1886 2006-12-04 Paul Eggert <eggert@cs.ucla.edu>
1888 * lib/autoconf/functions.m4 (AC_FUNC_FSEEKO): Check that fseeko
1889 can be assigned to a function pointer. Problem reported by
1890 Peter Palfrader in <http://bugs.debian.org/401377>. Based on
1891 part of a patch by Ralf Wildenhues in that same bug report.
1893 2006-12-01 Paul Eggert <eggert@cs.ucla.edu>
1895 * tests/mktests.sh (ac_exclude_list): Exclude AC_FUNC_SETVBUF_REVERSED.
1896 * tests/semantics.at (AC_FUNC_SETVBUF_REVERSED): New test.
1898 2006-12-01 Eric Blake <ebb9@byu.net>
1900 * lib/autoconf/c.m4 (AC_LANG_INT_SAVE): Avoid newline, to aid in
1901 cross-compiling from cygwin to mingw.
1902 Reported by Bob Rossi. This resurrects the 2000-11-30 patch to
1903 aclang.m4, which was mistakenly removed in the 2001-09-17 patch
1904 to lib/autoconf/c.m4.
1906 2006-12-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1908 * lib/m4sugar/m4sh.m4 (_AS_ECHO_PREPARE): Use a longer test
1909 string for more reliable failure. Wrap the entire test that
1910 causes the broken Solaris printf to dump core, in a subshell,
1911 so the segmentation fault message is reliably suppressed.
1912 Fix shell expansion errors by using /usr/ucb/echo always;
1913 avoid an error on systems without it by another subshell.
1914 Avoid m4 expansion of `$1'. Set the zeroth argument of the
1915 subshell-$as_echo to `as_echo', for better error message.
1917 2006-11-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1919 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): If `BASH_ARGV' or
1920 `BASH_SOURCE' contain a newline, set them to empty, as they may
1921 not be unset.
1923 2006-11-27 Paul Eggert <eggert@cs.ucla.edu>
1925 Turn AC_FUNC_SETVBUF_REVERSED into a noop. It's been obsolete for
1926 years and is too hard to maintain now. The last straw was
1927 reported by Jerker Baeck in
1928 <http://lists.gnu.org/archive/html/autoconf/2006-11/msg00102.html>.
1929 * NEWS: AC_FUNC_SETVBUF_REVERSED is now obsolete.
1930 * doc/autoconf.texi (Particular Functions): Move
1931 AC_FUNC_SETVBUF_REVERSED from here...
1932 (Obsolete Macros): ... to here. Say that it does nothing now.
1933 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
1934 Turn into (almost) a no-op.
1936 * lib/autoconf/c.m4 (AC_PROG_GCC_TRADITIONAL, AC_C_CONST):
1937 (AC_C_VOLATILE):
1938 Do not recommend via AN_FUNCTION, AN_IDENTIFIER, or AN_HEADER.
1939 These macros are obsolescent and new applications shouldn't need them.
1940 * lib/autoconf/functions.m4 (AC_FUNC_CLOSEDIR_VOID, AC_REPLACE_FNMATCH):
1941 (AC_FUNC_GETLOADAVG, AC_FUNC_GETPGRP, AC_FUNC_MEMCMP):
1942 (AC_FUNC_SELECT_ARGTYPES, AC_FUNC_SETPGRP, AC_FUNC_STAT, AC_FUNC_LSTAT):
1943 (AC_FUNC_STRFTIME, AC_FUNC_SETVBUF_REVERSED, AC_FUNC_UTIME_NULL):
1944 (AC_FUNC_VPRINTF): Likewise.
1945 * lib/autoconf/headers.m4 (AC_HEADER_DIRENT, AC_HEADER_STAT):
1946 (AC_HEADER_STDC, AC_HEADER_SYS_WAIT, AC_HEADER_TIME): Likewise.
1947 * lib/autoconf/types.m4 (AC_STRUCT_TM): Likewise.
1949 * doc/autoconf.texi (Setting Output Variables): Mention that
1950 @VAR1@VAR2 has unspecified behavior. Problem reported by
1951 Ralf Wildenhues.
1952 * NEWS: Mention this.
1954 * Makefile.am: Put only a single '#' into the copyright notice,
1955 so that it's also present in the output file. Standardize wording
1956 in makefile copyright notices to match GNU coding standards.
1957 * bin/Makefile.am: Likewise.
1958 * doc/Makefile.am: Likewise.
1959 * lib/Makefile.am: Likewise.
1960 * lib/freeze.mk: Likewise.
1961 * lib/autoconf/Makefile.am: Likewise.
1962 * lib/autoscan/Makefile.am: Likewise.
1963 * lib/autotest/Makefile.am: Likewise.
1964 * lib/m4sugar/Makefile.am: Likewise.
1965 * man/Makefile.am: Likewise.
1966 * tests/Makefile.am: Likewise.
1967 * lib/emacs/Makefile.am: Remove copyright notice; it's just a
1968 one-line file.
1970 2006-11-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1972 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Fix error
1973 in the sed script that mangles the awk script: delete up to the
1974 first exclamation mark only.
1975 * tests/torture.at (Substitute and define special characters):
1976 Test '!' too.
1978 2006-11-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1980 Rewrite config files generation: avoid quadratic growth in
1981 the number of substituted variables by using awk instead of sed
1982 for the bulk of the substitutions.
1983 * NEWS: Mention this.
1984 * doc/autoconf.texi (Setting Output Variables): `|#_!!_#|' is also
1985 forbidden in the output (and thus input) file.
1986 * lib/autoconf/status.m4 (_AC_AWK_LITERAL_LIMIT): New macro.
1987 (_AC_OUTPUT_FILES_PREPARE): Instead of several sed scripts,
1988 generate just one large awk script for substitutions,
1989 eliminating much of the earlier complexity, while adding some
1990 new complexity. Only expand the substitution templates at
1991 configure time, for smaller configure script size. If
1992 _AC_SUBST_FILES are used, test 'awk' for working getline support
1993 at config.status time. If absent, interpolate through the
1994 shell. The awk script was written with much help
1995 from Paolo Bonzini and Paul Eggert.
1996 (_AC_SED_CMD_NUM, _AC_SED_DELIM_NUM, _AC_SED_FRAG): Removed.
1997 (_AC_SED_FRAG_NUM): Likewise.
1998 (_AC_SUBST_CMDS): Renamed from...
1999 (_AC_SED_CMDS): ...this.
2000 (_AC_OUTPUT_FILE): Use _AC_SUBST_CMDS.
2001 * tests/torture.at (Substitute a 2000-byte string): Also
2002 substitute a line with 1000 words, and a variable with several
2003 long lines.
2004 (Substitute and define special characters): Test awk special
2005 characters, and put substitution input strings `@foo@' in the
2006 output, to test that no recursion happens; test several other
2007 combinations from Paolo Bonzini.
2009 2006-11-25 Paul Eggert <eggert@cs.ucla.edu>
2011 * lib/autotest/general.m4 (AT_INIT): Undo recent changes
2012 that replaced echo with AS_ECHO where this wasn't necessary.
2013 Problem reportd by Ralf Wildenhues.
2014 * lib/m4sugar/m4sh.m4 (_AS_ECHO_PREPARE): Port to Solaris 7,
2015 where "/usr/bin/printf '%s\n' S" dumps core if S is long.
2016 This is Sun bug 4206210. Problem reportd by Ralf Wildenhues.
2018 2006-11-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2020 * lib/freeze.mk (GREP): Removed, no need to initialize this.
2022 2006-11-21 Paul Eggert <eggert@cs.ucla.edu>
2024 * doc/autoconf.texi (Limitations of Usual Tools): Don't claim
2025 that traditional Awk lacks 3-arg "split". It has it.
2026 Mention that FS must be a single character, and a few other
2027 99-byte limits of traditional Awk.
2028 Mention that if (i in a) doesn't work with traditional Awk.
2030 2006-11-18 Paul Eggert <eggert@cs.ucla.edu>
2032 * tests/autotest.at (BSx641-newline in command):
2033 (BS-BS-newline in command, BSx640-newline in command):
2034 (Newline-CODE-BS-newline in command):
2035 (Single-quote-BS-newline in command):
2036 (Single-quote-newline-BS-newline in command):
2037 Use printf '%s\n' instead of echo, for portability to hosts
2038 where echo interprets backslashes. This will break on hosts
2039 that lack printf, but for now let's assume all such hosts
2040 are dead (if not, we should get reports of test failures).
2042 2006-11-17 Paul Eggert <eggert@cs.ucla.edu>
2044 'echo' has some portability problems, when given a first argument
2045 with a leading '-', or when given any argument containing '\'.
2046 Avoid using 'echo' in these cases.
2047 * bin/Makefile.am $(bin_SCRIPTS): Rewrite to avoid 'echo' entirely.
2048 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX, AC_PROG_OBJC): Likewise.

2050 * lib/autotest/general.m4 (AT_INIT): Likewise.
2051 * bin/autoconf.as: Use AS_ECHO rather than plain echo, when the
2052 argument might be unportable.

2054 * lib/autoconf/erlang.m4 (AC_LANG(Erlang)): Likewise.

2071 (AS_TR_SH, AS_TR_CPP, AS_VAR_GET): Likewise.
2072 * bin/autoconf.as: Redo verbose flag implementation, as the old
2073 scheme wouldn't work with AS_ECHO.
2074 * lib/autotest/general.m4 (AT_INIT): Likewise.
2075 * lib/autoconf/general.m4 (AC_MSG_RESULT, AC_MSG_RESULT_UNQUOTED):
2076 Don't use ECHO_T, since ECHO_N is now reliable.
2077 * lib/autotest/general.m4 (AT_INIT): Likewise.
2078 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Use sed "$script"
2079 rather than using a here-document to put the script into a file.
2080 (_AC_DO_ECHO): Hoist the eval out of the echo, so that we can
2081 use AS_ECHO.
2082 * lib/m4sugar/m4sh.m4 (AS_VAR_GET): Likewise.
2083 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Use
2084 AS_ECHO_N rather than ECHO_N and ECHO_C. This doesn't fix any
2085 bug, but we might as well stop using ECHO_N and ECHO_C internally.
2086 * lib/autotest/general.m4 (AT_SETUP): Likewise.
2087 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N): Likewise.
2088 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
2089 (_AC_OUTPUT_MAIN_LOOP): Rework echo so that it has just one
2090 operand, as AS_ECHO requires. Avoid double file name expansion.
2091 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Invoke _AS_ECHO_PREPARE.
2092 Don't set as_nl, since _AS_ECHO_PREPARE does that now.
2093 (_AS_PREPARE): Comment that _AS_ECHO_N_PREPARE is just for user code.
2094 (AS_ECHO, AS_ECHO_N, _AS_ECHO_PREPARE): New macros.
2095 * tests/c.at (AC_PROG_CPP without warnings, AC_PROG_CPP via CC):
2096 Double-quote strings that would otherwise contain M4 comments.
2097 * tests/m4sh.at (AS_ECHO and AS_ECHO_N): New test.
2099 * configure.ac (AC_INIT): Bump to 2.61a.
2100 * NEWS: Likewise.
2102 2006-11-17 Paul Eggert <eggert@cs.ucla.edu>
2104 Version 2.61.
2106 * configure.ac (AC_INIT): Bump to 2.61.
2107 * NEWS: Likewise.
2109 * tests/autotest.at (Macro with backslash in a test title):
2110 Comment out for now, as this tests neither fails nor passes
2111 reliably. Problem reported by Ralf Wildenhues.
2113 2006-11-16 Paul Eggert <eggert@cs.ucla.edu>
2115 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE): Fix some typos
2116 in previous change, which caused test failures.
2118 2006-11-16 Stepan Kasal <kasal@ucw.cz>
2120 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Factor out
2121 code for --enable, --disable, --with, and --without to...
2122 (_AC_INIT_PARSE_ENABLE): ... a new macro.
2123 * doc/autoconf.texi (Package Options):
2124 * NEWS: Document that AC_ARG_ENABLE allows dots, too.
2126 2006-11-16 Paul Eggert <eggert@cs.ucla.edu>
2128 Import these changes from config via gnulib:
2130 2006-11-15 Ben Elliston <bje@gnu.org>
2132 From Josselin Mouette <joss@debian.org>:

2203 * lib/autoconf/types.m4 (AC_TYPE_LONG_LONG_INT): Set
2204 ac_cv_type_long_long_int to 'yes' instead of 'cross-compiling'.
2205 Imported from a similar patch to gnulib by Bruno Haible.
2207 2006-11-08 Paul Eggert <eggert@cs.ucla.edu>
2209 * NEWS: New macros AC_C_FLEXIBLE_ARRAY_MEMBER, AC_C_VARARRAYS.

2218 Matthew Woehlke.
2220 2006-10-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2222 * tests/torture.at (Configuring subdirectories): Do not skip
2223 Automake 1.10 nor future Automake 11.1 (sic).
2225 2006-10-26 Joel E. Denny <jdenny@ces.clemson.edu>
2226 and Stepan Kasal <kasal@ucw.cz>
2228 Handle special characters in test case titles correctly.
2229 * lib/autotest/general.m4 (AT_INIT): M4-quote and AS_ESCAPE AT_help_all

2236 Single-quote in a test title,
2237 Double-quote in a test title): Don't expect failure anymore.
2238 (Backslash in a test title): Put a non-whitespace character after the
2239 backslash so that Bourne shells might actually see it as an escape
2240 sequence.
2241 (Brackets in a test title,
2242 Pound in a test title,
2243 Comma in a test title,
2244 Quoted Macro in a test title,

2259 2006-10-26 Paul Eggert <eggert@cs.ucla.edu>
2261 * tests/base.at (AC_COMPUTE_INT): Test **0** rather than 1 / 0,
2262 since powerpc-apple-darwin8-gcc-4.0.1 (Apple Computer, Inc. build
2263 5363) simply issues a warning when dividing by zero at compile
2264 time. Problem reported by Elias Pipping.
2266 2006-10-26 Eric Blake <ebb9@byu.net>
2268 * THANKS: Update.
2269 * doc/autoconf.texi (Evaluation Macros): Improve the example to
2270 show effect on macros that expand with commas.

2286 2006-10-24 Paul Eggert <eggert@cs.ucla.edu>
2288 * doc/autoconf.texi (Limitations of Usual Tools): Document that rm

2300 reported by Nelson H. F. Beebe for Coreutils 6.4.
2302 * tests/tools.at (autoconf --trace: user macros): Remove test
2303 for tracing multiline macros, since m4 1.4.7a uses a different
2304 way to number lines. Problem reported by Ralf Wildenhues.
2306 2006-10-24 Stepan Kasal <kasal@ucw.cz>
2308 * bin/autom4te.in (handle_m4): Do not redirect stdin to
2309 /dev/null since the heuristics for interactive behaviour was
2310 fixed in CVS m4.
2312 * bin/autom4te.in: With --force, always refresh the output
2313 file. Problem reported by Greg Schafer <gschafer@zip.com.au>.

2373 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL):
2374 (_AC_CHECK_HEADER_NEW, _AC_CHECK_HEADER_OLD, _AC_CHECK_HEADER_DIRENT):
2375 Likewise.
2376 * lib/autotest/general.m4 (AT_INIT): Quote parameters of
2377 AS_VAR_* properly.

2380 2006-10-14 Paul Eggert <eggert@cs.ucla.edu>
2382 (Imported from Automake.)
2383 * build-aux/install-sh (posix_mkdir): Reject FreeBSD 6.1 mkdir -p -m,
2384 which incorrectly sets the mode of an existing destination
2385 directory. In some cases the unpatched install-sh could do the
2386 equivalent of "chmod 777 /" or "chmod 0 /" on a buggy FreeBSD
2387 system. We hope this is rare in practice, but it's clearly worth
2388 fixing. Problem reported by Alex Unleashed in
2389 <http://lists.gnu.org/archive/html/bug-autoconf/2006-10/msg00012.html>.
2390 Also, don't bother to check for -m bugs unless we're using -m;
2391 suggested by Stepan Kasal.
2393 2006-10-14 Paul Eggert <eggert@cs.ucla.edu>
2395 Import this change from Automake:
2397 2006-08-23 Alexandre Duret-Lutz <adl@gnu.org>
2398 * lib/Autom4te/ChannelDefs.pm (usage): Mention that -Wportability
2399 is enabled by default with gnu and gnits strictness.
2400 Report from Bruno Haible.
2402 2006-03-10 Alexandre Duret-Lutz <adl@gnu.org>
2403 * lib/Autom4te/ChannelDefs.pm: Make -Wportability the default in
2404 gnu and gnits modes.
2406 Import this change from Config:
2408 2006-09-20 Ben Elliston <bje@gnu.org>
2409 * build-aux/config.sub (score, score-*): New.
2411 Import this change from Gnulib:
2413 2006-09-16 Karl Berry <karl@gnu.org>
2414 * doc/fdl.texi (ADDENDUM): switch to @heading from @appendixsubsec,
2415 to avoid sectioning errors.
2417 Import these changes from Texinfo:
2419 2006-10-04 Karl Berry <karl@gnu.org>
2420 * build-aux/texinfo.tex (\singlequotechar): rename to \codequoteright.
2421 (\quoteexpand): rename to \rquoteexpand.
2422 (\codequoteleft): new def, to look for @set codequotebacktick.
2423 (\lquoteexpand, \quoteexpand): new defs.
2424 (\lquoteChar, \rquoteChar, \dashChar, \underChar: new \chardef's.
2425 (\code): must use new \...Char values, since now ` is active.
2427 2006-08-26 Karl Berry <karl@gnu.org>
2428 * build-aux/texinfo.tex (\textdegree): New command.
2430 2006-08-12 Karl Berry <karl@gnu.org>
2431 * build-aux/texinfo.tex (error \box0): smaller font.
2433 2006-10-14 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2435 * doc/autoconf.texi (Autoheader Macros): Fix syntax error.
2437 2006-10-13 Stepan Kasal <kasal@ucw.cz>
2439 * doc/autoconf.texi (Autoheader Macros): Warn that the text
2440 added to the template can get mangled.
2442 2006-10-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2444 * lib/autoconf/functions.m4 (AC_FUNC_OBSTACK): In the test,
2445 include the default headers, and redefine obstack_chunk_alloc
2446 and obstack_chunk_free. Fixes false failure with glibc.
2448 2006-10-12 Paul Eggert <eggert@cs.ucla.edu>
2450 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Set as_executable_p,
2451 for backward compatibility with Libtool 1.5.22. Problem reported
2452 by Ralf Wildenhues.
2454 2006-10-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2456 * lib/autoconf/c.m4 (AC_PROG_GCC_TRADITIONAL): Require
2457 AC_PROG_CC.

2460 2006-10-11 Paul Eggert <eggert@cs.ucla.edu>
2462 * NEWS: AC_USE_SYSTEM_EXTENSIONS now defines _TANDEM_SOURCE for
2463 the NonStop platform.
2464 * doc/autoconf.texi (Posix Variants): Likewise.
2465 * lib/autoconf/specific.m4 (AC_USE_SYSTEM_EXTENSIONS): Likewise.
2467 * lib/m4sugar/m4sh.m4 (AS_TEST_X): New macro.
2468 (AS_EXECUTABLE_P): Use as_test_x rather than as_executable_p.
2469 (_AS_TEST_PREPARE): Set as_test_x rather than as_executable_p.
2470 Use a better substitute, by inspecting the output of "ls"
2471 rather than just using ":".
2472 * lib/autoconf/general.m4 (_AC_LINK_IFELSE): Use AS_TEST_X
2473 rather than AS_EXECUTABLE_P, since we needn't worry about
2474 non-regular files here.
2476 * NEWS: Autoconf-generated shell scripts no longer export BIN_SH,
2477 due to configuration hassles with this. See Tonya Underwood's report
2478 <http://lists.gnu.org/archive/html/bug-autoconf/2006-10/msg00003.html>.

2482 Stepan Kasal <kasal@ucw.cz>
2484 * lib/m4sugar/m4sh.m4 (AS_BOURNE_COMPATIBLE): Don't set BIN_SH.
2485 (_AS_DETECT_BETTER_SHELL): Don't look in /usr/bin/posix.
2487 2006-10-11 Stepan Kasal <kasal@ucw.cz>
2489 * lib/m4sugar/m4sh.m4 (AS_BOURNE_COMPATIBLE): Move the
2490 initialization which is not inherited through the environment
2491 (_AS_BOURNE_COMPATIBLE): ... to this new macro.
2492 (_AS_RUN): Call _AS_BOURNE_COMPATIBLE, not AS_BOURNE_COMPATIBLE.
2494 2006-10-09 Paul Eggert <eggert@cs.ucla.edu>
2496 * doc/autoconf.texi (Limitations of Usual Tools): Describe
2497 problems with mkdir -p -m.
2499 2006-10-06 Paul Eggert <eggert@cs.ucla.edu>
2501 * lib/autoconf/c.m4 (_AC_PROG_PREPROC_WORKS_IFELSE): Remove
2502 comment about ac_cpp_err; it was incorrect, and anyway
2503 ac_cpp_err is being removed below.
2504 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE): Don't
2505 set ac_cpp_err to 'yesyes' if preproc_warn_flag and werror_flag
2506 are both 'yes'. In fact, don't bother setting ac_cpp_err at all;
2507 nobody uses it.
2508 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't log our funky tests
2509 with werror_flag and conftest.err and so forth. This is more
2510 compatible with how _AC_PROG_PREPROC_WORKS_IFELSE behaves,
2511 and anyway the user shouldn't normally want to see this gorp logged.
2512 Problem reported by Ralf Wildenhues.
2513 * lib/autoconf/lang.m4 (AC_LANG_WERROR): werror_flag's default is
2514 empty, not 'no', since the rest of the code uses 'test -z'.
2516 2006-10-04 Paul Eggert <eggert@cs.ucla.edu>
2518 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE):
2519 Use a single call to AC_DO_TOKENS rather than multiple, for
2520 efficiency.
2521 (_AC_LINK_IFELSE): Test that resulting file is executable.
2522 Problem reported by mwoehlke in
2523 <http://lists.gnu.org/archive/html/bug-coreutils/2006-10/msg00048.html>.
2525 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Use "test -x /" rather
2526 than creating a file to use with test -x; this is much faster.
2528 2006-10-02 Bruno Haible <bruno@clisp.org>
2530 * lib/autom4te.in (Automake-preselections): Add
2531 AM_GNU_GETTEXT_INTL_SUBDIR, for automake 1.10.
2533 2006-09-27 Stepan Kasal <kasal@ucw.cz>
2535 * doc/autoconf.texi (Writing testsuite.at): Fix a typo: for
2536 standard error, `experr' should be used, not `expout'.
2538 2006-09-26 Paul Eggert <eggert@cs.ucla.edu>
2540 * lib/autoconf/functions.m4 (AC_FUNC_FSEEKO): Don't compile the
2541 fseeko testing program twice; just use the earlier result.
2542 * lib/autoconf/specific.m4 (_AC_SYS_LARGEFILE_MACRO_VALUE):
2543 Set cache var to 'unknown' (not 'no') if leaving the macro unset
2544 still doesn't let the program compile.
2545 (AC_SYS_LARGEFILE): Test for _LARGE_FILES only if earlier tests
2546 failed.
2548 * lib/autoconf/functions.m4: Fix problems reported by Ralf Wildenhues.
2549 (AC_FUNC_ERROR_AT_LINE): Don't bother to check for error.h. Just
2550 include it, without including anything else.
2551 (AC_FUNC_FSEEKO): Avoid gcc -Wall warnings about constant
2552 expressions.
2553 (AC_FUNC_STRNLEN): Require AC_USE_SYSTEM_EXTENSIONS.
2555 2006-09-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2557 * lib/autoconf/functions.m4 (AC_FUNC_ERROR_AT_LINE): Check for
2558 `error.h', and include it, for a `error_at_line' prototype.
2559 Use a nonempty format string in the link test.
2560 * lib/autoconf/functions.m4 (AC_FUNC_WAIT3): Include <sys/wait.h>,
2561 for a declaration of wait3.
2563 2006-09-26 Paul Eggert <eggert@cs.ucla.edu>
2565 * NEWS: AC_CHECK_DECL now also works with aggregate objects.
2566 * doc/autoconf.texi (Generic Declarations): Clarify that AC_CHECK_DECL
2567 can apply to constants too, and that it checks for macro defns.
2568 * lib/autoconf/general.m4 (AC_CHECK_DECL): Assume C89 or better,
2569 and simply cast the identifier to void. This handles structure
2570 values. Problem reported by Ralf Wildenhues.
2571 * tests/semantics.at (AC_CHECK_DECLS): Also check enums.
2573 2006-09-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2575 * tests/semantics.at (AC_CHECK_DECLS): Also check macros,
2576 structure, and function symbols.
2578 2006-09-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2580 * tests/semantics.at (AC_CHECK_MEMBERS): Also test with a struct
2581 member.

2627 * bin/autom4te.in (handle_m4): Favor --debugfile over misnamed
2628 --error-output, to avoid warnings with M4 2.0.
2630 2006-09-19 Stepan Kasal <kasal@ucw.cz>
2632 * lib/autoconf/libs.m4 (AH_CHECK_LIB): Fix quoting, to be

2643 * lib/autoconf/general.m4 (AC_CONFIG_MACRO_DIR): Remove a
2644 mistaken comment: the path has to be relative; do not use
2645 the path at runtime.
2647 2006-09-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2649 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Quote the

2653 for both changes.
2654 * doc/autoconf.texi (Setting Output Variables): Fix example to
2655 not show `--silent' being passed to a `configure' re-run.
2657 2006-09-12 Paul Eggert <eggert@cs.ucla.edu>
2659 * doc/autoconf.texi (Input): Clarify role of AC_CONFIG_MACRO_DIR.
2660 * lib/autoconf/general.m4 (AC_CONFIG_MACRO_DIR): Do not check
2661 for the existence of the directory at configure-time. That's
2662 too late, anyway. Problem reported by Stefan Seefeld.
2664 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Avoid bug in UnixWare
2665 7.1.4 /usr/bin/posix/sh described by Tim Rice in
2666 <http://lists.gnu.org/archive/html/bug-autoconf/2006-09/msg00017.html>.
2668 2006-09-11 Stepan Kasal <kasal@ucw.cz>
2670 * tests/local.at (AT_CHECK_M4): Fix this so that the testsuite
2671 works with GNU M4 1.4.3 again; make the normalized form
2672 match the current m4 message; fix the description.
2673 * test/tools.at (autom4te cache): Adapt to the change.
2675 2006-09-08 Paul Eggert <eggert@cs.ucla.edu>
2677 * lib/autoconf/functions.m4 (AC_FUNC_MKTIME): Add year_2050_test
2678 to catch glibc bug 2821
2679 <http://sourceware.org/bugzilla/show_bug.cgi?id=2821>.
2681 Merge from gnulib as follows: Use AC_CHECK_HEADERS_ONCE instead of
2682 AC_CHECK_HEADERS, and likewise for AC_CHECK_FUNCS_ONCE and
2683 AC_CHECK_FUNCS. Don't check for stdlib.h, since we now
2684 assume C89.
2686 2006-09-08 Stepan Kasal <kasal@ucw.cz>
2688 * lib/autom4te.in (Autoconf-without-aclocal-m4): Move the

2702 by Dries Kimpe.
2704 2006-09-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2706 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Prefer xlf90/xlf95 over
2707 f90/f95 because the latter drivers of AIX Fortran 9.1 do not
2708 accept files with extension `.f'. For consistency, also prefer
2709 xlf over f77.
2710 * doc/autoconf.texi (Fortran Compiler): Remove mention of bug
2711 from last patch.
2713 2006-09-05 Romain Lenglet <rlenglet@users.forge.objectweb.org>

2728 2006-09-01 Paul Eggert <eggert@cs.ucla.edu>
2730 * NEWS: New macro AC_CACHE_CHECK_INT. It replaces the
2731 old AC_COMPUTE_INT, which now behaves like _AC_COMPUTE_INT
2732 except the first two arguments are reversed.
2733 * doc/autoconf.texi (Caching Results): New macro AC_CACHE_CHECK_INT.
2734 (Generic Compiler Characteristics): AC_COMPUTE_INT no longer
2735 caches nor outputs a diagnostic. Suggested by Bruno Haible.
2736 * lib/autoconf/general.m4 (AC_CACHE_CHECK_INT): New macro,
2737 equivalent to the old AC_COMPUTE_INT.
2738 (AC_COMPUTE_INT): No longer caches or reports. New signature.
2739 All uses changed to AC_CACHE_CHECK_INT.
2740 * tests/base.at (AC_CACHE_CHECK_INT): New test.
2741 * tests/mktests.sh (ac_exclude_list): Add AC_CACHE_CHECK_INT.
2743 2006-08-31 Paul Eggert <eggert@cs.ucla.edu>
2745 * NEWS: AC_FUNC_FNMATCH, AC_FUNC_FNMATCH_GNU, AC_FUNC_GETLOADVG,
2746 and AC_REPLACE_FNMATCH are now obsolescent in Autoconf. New
2747 programs should use their Gnulib counterparts.
2748 * doc/autoconf.texi (Particular Functions): Likewise.
2749 (Macro Names, testsuite Invocation): Replace uses of these
2750 obsolete macros with uses of non-obsolete macros.

2776 2006-08-25 Paul Eggert <eggert@cs.ucla.edu>
2778 Fix Lex library problem reported to us by Julio Garvia.
2779 * doc/autoconf.texi (Particular Programs): YYTEXT_POINTER is
2780 for the default, which the user can override.
2781 * lib/autoconf/programs.m4 (AC_PROG_LEX): Let _AC_PROG_LEX_YYTEXT_DECL
2782 deal with LEXLIB.
2783 (_AC_PROG_LEX_YYTEXT_DECL): Handle caching correctly; the old code
2784 didn't work if some values were cached but not others. Test for
2785 broken lex libraries like native ia64-hp-hpux11.22; see
2786 <http://sources.redhat.com/ml/binutils/2003-12/msg00337.html>, and
2787 work around the problem by preferring an empty LEXLIB to -lfl or
2788 -ll. Let the user set LEXLIB='' to indicate no library needed.
2790 * NEWS: Recommend M4 1.4.6 instead of 1.4.5.

2887 * lib/autoconf/c.m4 (_AC_PROG_CC_C99): Test varargs macros and
2888 64-bit preprocessor ints. Check for static initialization of
2889 long long. Remove unnecessary casts.
2891 2006-08-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2893 * doc/autoconf.texi (Particular Programs): Mention that
2894 @INSTALL@ and @MKDIR_P@ may vary for different output files.
2895 Reported by Alexandre Duret-Lutz.
2897 2006-08-24 Paul Eggert <eggert@cs.ucla.edu>
2899 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS): Also ignore
2900 -lgcc?* and -lSystem, for Darwin/MacOS X. Problem reported by
2901 Bill Northcott in
2902 <http://lists.gnu.org/archive/html/autoconf/2006-08/msg00083.html>.

2906 * lib/autoconf/c.m4 (AC_C_CONST): Don't used shadowed vars, to
2907 pacify insanely picky compilers. Problem reported by Eric Blake.
2909 * doc/autoconf.texi (Posix Variants): INTERACTIVE Unix is no
2910 longer supported by Sun.
2912 2006-08-15 Paul Eggert <eggert@cs.ucla.edu>
2914 * NEWS: Autoconf now uses constructs like "#ifdef HAVE_STDLIB_H"
2915 rather than "#if HAVE_STDLIB_H", so that it now works with "gcc
2916 -Wundef -Werror". Problem reported by David Fang in
2917 <http://lists.gnu.org/archive/html/autoconf/2006-08/msg00045.html>.
2918 * doc/autoconf.texi (Header Templates, Default Includes):

2920 (Particular Headers, Generic Headers, Generic Declarations, Guidelines):
2921 (Obsolete Macros, AC_FOO_IFELSE vs AC_TRY_FOO):

2933 * lib/autoconf/headers.m4 (AC_HEADER_STAT): Don't assume that
2934 S_ISDIR etc. are valid for use in #if; POSIX doesn't guarantee
2935 this.
2937 2006-08-14 Paul Eggert <eggert@cs.ucla.edu>
2939 * doc/autoconf.texi (Limitations of Usual Tools): Document sed
2940 problems with arg script text that doesn't end in newline, and
2941 with '-e a...'. Problems reported by Ralf Wildenhues.
2943 2006-08-12 Alexandre Julliard <julliard@winehq.org> (tiny change)
2945 * lib/autoconf/libs.m4 (AC_PATH_X_DIRECT): Replace another
2946 check for libXt by a check for libX11.
2948 2006-08-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

2951 to last change.
2953 2006-08-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2955 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): `config.status
2956 --help' should mention that `--version' outputs configuration
2957 settings. Report by Bruno Haible.
2959 2006-08-06 Paul Eggert <eggert@cs.ucla.edu>
2961 Fix test suite failures reported by Pierre in
2962 <http://lists.gnu.org/archive/html/bug-autoconf/2006-08/msg00005.html>.
2963 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't claim
2964 the compiler created a file "b.out" when it didn't create anything
2965 at all.

2967 Discard stderr too, when invoking the test script.

2971 * lib/autoconf/libs.m4 (AC_PATH_XTRA): Fixed a typo
2972 in the restoring of the werror flag.
2974 2006-07-24 Paul Eggert <eggert@cs.ucla.edu>

2977 less skeptical about "volatile", after discussion with
2978 Bruno Haible on bug-gnulib.
2979 (Limitations of Usual Tools): Warn about sed stripping
2980 leading white space from text. From Bruno Haible.
2982 2006-07-20 Paul Eggert <eggert@cs.ucla.edu>
2984 * lib/autoconf/libs.m4 (AC_PATH_XTRA): Don't use -R if the
2985 compiler complains about it, even if things works after the
2986 complaint. Problem reported by Peter O'Gorman.
2988 * doc/autoconf.texi (Preset Output Variables): Document CFLAGS,
2989 CPPFLAGS, and LDFLAGS better. Problem reported by Bruno Haible.
2990 Similarly for CXXFLAGS, OBJCFLAGS, ERLCFLAGS.
2992 2006-07-17 Paul Eggert <eggert@cs.ucla.edu>
2994 * lib/autoconf/libs.m4 (AC_PATH_XTRA): Do the check for space
2995 after -R regardless of host. Patrick Welche reports that this

2999 * README: Likewise.
3000 * doc/autoconf.texi (Introduction, Why GNU M4): Likewise.
3001 * tests/tools.at (autom4te cache): Update wording of diagnostic
3002 to match M4 1.4.5.
3004 2006-07-07 Paul Eggert <eggert@cs.ucla.edu>
3006 * doc/autoconf.texi (C Compiler): Add a ref to Volatile Objects
3007 under AC_C_VOLATILE.
3008 (Volatile Objects): Be a little less skeptical about what
3009 "volatile" means. Derived from thoughts by Ben Pfaff in
3010 <http://lists.gnu.org/archive/html/bug-gnulib/2006-07/msg00092.html>.
3012 2006-07-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3014 * doc/autoconf.texi: Fix some typos.
3016 2006-07-07 Paul Eggert <eggert@cs.ucla.edu>
3018 * tests/torture.at (Configuring subdirectories): Set CONFIG_SITE
3019 more globally, since the 2006-06-30 patch didn't suffice. Problem
3020 reported by Keith Marshall. Also, don't bother with builddir2,
3021 since it shouldn't be needed any more.
3023 2006-07-07 Paolo Bonzini <bonzini@gnu.org>
3025 * doc/autoconf.texi (Generic compiler characteristics):
3026 Document AC_COMPUTE_INT. Fix wrong statements on Default
3027 Includes for AC_CHECK_SIZEOF and AC_CHECK_ALIGNOF.
3029 * lib/autoconf/general.m4 (AC_COMPUTE_INT): New.
3030 (_AC_COMPUTE_INT): Add obsoletion warnings.

3032 AC_COMPUTE_INT.
3034 * NEWS: Document change.
3036 2006-07-05 Paul Eggert <eggert@cs.ucla.edu>
3038 * doc/autoconf.texi (Volatile Objects): New section.
3040 * NEWS: Document previous change.
3042 2006-07-02 Paul Eggert <eggert@cs.ucla.edu>
3044 * lib/autoconf/types.m4 (AC_TYPE_LONG_LONG_INT):
3045 Require that long long int be at least 64 bits wide. C99 requires
3046 this and enough programs depend on it so we should check for it.
3047 Bruno Haible reports in
3048 <http://lists.gnu.org/archive/html/bug-gnulib/2006-06/msg00286.html>
3049 that long long int is 32 bits wide with some nonstandard compilers.
3050 (AC_TYPE_UNSIGNED_LONG_LONG_INT): Likewise.
3052 2006-06-30 Paul Eggert <eggert@cs.ucla.edu>
3054 * tests/torture.at (Configuring subdirectories): Set CONFIG_SITE
3055 to a nonexistent file, so that we don't have to worry about
3056 a local site configuration that doesn't use /usr/local.
3057 Problem reported by Keith Marshall in
3058 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00133.html>.
3060 2006-06-28 Paul Eggert <eggert@cs.ucla.edu>
3062 * doc/autoconf.texi: Be more consistent about using @acronym with
3063 "HP" and "HP-UX". Remove mention of OSF; the old version wasn't
3064 quite right (it talked about "OSF/Tru64", even though the
3065 operating systems were called OSF/1, Digital UNIX, and Tru64 UNIX,
3066 and it even mentioned "OSF 4"!) and at this point there's little
3067 reason to talk about OSF any more, since it died in 1994.
3068 (Specific Compiler Characteristics): Simplify example of
3069 negative-size array.
3070 (File Descriptors): Reorder to make the text flow better.
3071 Remove joke about "appreciate the various levels"; I didn't get it.
3072 Add remark about HP-UX sh -x bug with stderr noted by Bob Proulx in
3073 <http://lists.gnu.org/archive/html/bug-coreutils/2006-06/msg00225.html>.
3074 (File Descriptors, Limitations of Usual Tools):
3075 Tone down the advice against renaming or removing open files.
3076 (Limitations of Usual Tools): Add a new section, on 'rm'.
3078 2006-06-26 Stepan Kasal <kasal@ucw.cz>
3080 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Use -lX11, not
3081 -lXt in LIBS, idea from Karsten Hopp; this was due since
3082 this change:
3084 2005-09-18 Paul Eggert <eggert@cs.ucla.edu>
3085 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Look for X11/Xlib.h
3086 and XrmInitialize rather than X11/Intrinsic.h and XtMalloc
3087 (which belong to Xt, not X itself). See Debian bug 327655.
3089 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3091 * configure.ac (AC_INIT): Bump to 2.60a.
3092 * NEWS: Update.
3094 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3096 Version 2.60.
3098 * configure.ac, NEWS: Update.
3100 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3102 * config/texinfo.tex: Sync from upstream.
3104 * bin/autom4te.in (handle_traces): Transform the `@S|@'
3105 quadrigraph correctly in traces.
3107 * NEWS, lib/Autom4te/C4che.pm, lib/autoconf/functions.m4:
3108 Fix typos.
3110 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Expand tests for
3111 datarootdir-related errors only if AC_DATAROOTDIR_CHECKED is
3112 not defined.
3113 * doc/autoconf.texi (Changed Directory Variables): New node,
3114 to document the whole `datarootdir' business a bit better.
3115 * NEWS: Update.
3116 * tests/torture.at (datarootdir workaround): Extend test.
3117 Prompted by report by Alexandre Julliard.
3119 2006-06-22 Paul Eggert <eggert@cs.ucla.edu>
3121 * lib/autoconf/c.m4 (_AC_PROG_CC_C89): Check for C89 incompatibility
3122 when using default mode of IBM C 6 for AIX. Problem and two-line
3123 fix reported by Larry Jones.
3125 2006-06-22 Alexandre Julliard <julliard@winehq.org>
3127 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Avoid warning
3128 about literal '${datarootdir}' if a definition is found in the
3129 output file.
3131 2006-06-20 Paul Eggert <eggert@cs.ucla.edu>
3133 * NEWS: Use "M4" rather than "m4" when appropriate.
3134 Problem reported by Eric Blake.
3135 * doc/autoconf.texi: Likewise.
3136 Use @acronym around BSD, GCC, and GNU when appropriate.
3137 (Why GNU M4): Renamed from "Why GNU m4".
3138 (Redefined M4 Macros): Mention that Posix
3139 m4wrap takes only 1 argument, but GNU M4 1.4.x takes more.
3140 (Buffer Overruns): Mention size_t and ptrdiff_t as alternatives
3141 to int.
3143 2006-06-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3145 * bin/autom4te.in (handle_output): Do not forbid the empty
3146 pattern.
3147 * tests/tools.at (autoconf: the empty token): New test.
3149 2006-06-20 Stepan Kasal <kasal@ucw.cz>
3151 * lib/m4sugar/m4sugar.m4 (m4_init): Merge the two m4_wrap
3152 calls, so that we do not care whether they are LIFO or FIFO;
3153 in the m4_wrap, do not check which diversion is the topmost
3154 one, just check that the stack is balanced at the end.
3155 * lib/m4sugar/m4sh.m4 (AS_INIT): We are going to change the
3156 base diversion forever--pop the previous diversion before
3157 opening the new one; consequently, remove the m4_wrap call.
3158 * lib/autotest/general.m4 (AT_INIT): Likewise.
3159 * tests/m4sugar.at: Do not use
3160 m4_wrap([m4_diversion_pop([..])]), for educational purposes.
3162 2006-06-19 Paul Eggert <eggert@cs.ucla.edu>
3163 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3165 * NEWS: Document that m4wrap/m4_wrap might not be LIFO.
3166 * doc/autoconf.texi (Redefined M4 Macros): Likewise.
3167 Rework example of m4wrap token-pasting trouble so that it doesn't
3168 care whether it's LIFO or FIFO.
3169 Fix some "contrary to"s that are awkward in English.
3171 2006-06-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3173 * lib/autoconf/types.m4 (_AC_TYPE_INT): Set `$ac_cv_c_int$1_t'
3174 to `yes' instead of `int$1_t' if the type is found, for more
3175 consistent configure output (where $1 is the number of bits).
3176 (_AC_TYPE_UINT): Likewise for `uint$1_t'.
3177 Suggested by Bruno Haible.
3179 * lib/autoconf/types.m4 (_AC_TYPE_UNSIGNED_INT): Solaris 2.5.1
3180 needs _UINT8_T and _UINT64_T defines as well, to avoid clashes
3181 with system headers. Report by Bruno Haible.
3183 2006-06-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3185 * config/config.guess, config/config.sub: Sync from upstream.
3187 * bin/Makefile.am (autoconf.in): Use `--melt' for autom4te,
3188 in order to avoid picking up an older installed frozen m4sh.m4f.
3189 Besides an outdated shell startup, this could have been created
3190 by an earlier M4 version with incompatible frozen file format.
3192 2006-06-16 Paul Eggert <eggert@cs.ucla.edu>
3194 * README: Recommend m4 1.4.4 instead of 1.4.3..
3195 * doc/autoconf.texi: Likewise.
3196 (Special Chars in Names): Say that $(.FOO) is portable, as
3197 suggested by Stepan Kasal.
3198 (Installation Directory Variables, Build Directories):
3199 (Automatic Remaking, Subdirectories, Fortran Compiler):
3200 (Making testsuite Scripts, Defining Directories):
3201 Quote variable usages better.
3202 (Making testsuite Scripts): Add clean-local rule to makefile
3203 snippet, by Eric Blake.
3204 (Installation Directory Variables): Fix table item font.
3205 Reword slightly to clarify. Generalize advice about
3206 not using special characters to include all file-related
3207 vars, not just VPATH.
3208 (Special Chars in Variables): Warn about special characters in
3209 $(srcdir) too.
3210 (Assignments): Clarify default-value example as suggested by
3211 Ralf Wildenhues in
3212 <http://lists.gnu.org/archive/html/autoconf-patches/2006-06/msg00072.html>.
3213 (Special Shell Variables): Note leading ./ or ../, as suggested
3214 by Eric Blake.
3215 (Limitations of Builtins): Under cd, warn about CDPATH.
3216 (The Make Macro MAKEFLAGS): Untabify. Problem reported by
3217 Ralf Wildenhues.
3219 2006-06-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3221 * doc/autoconf.texi (Configuration Actions): Remove duplicate
3222 `@var', for texi2html.
3223 (Systemology): Some more word wrapping, for DVI output.
3224 (autom4te Invocation): The short option for `--melt' is `-M',
3225 not `-m'.
3227 2006-06-15 Paul Eggert <eggert@cs.ucla.edu>
3229 * doc/autoconf.texi: More formatting and English tweaks,
3230 many suggested by Ralf Wildenhues.
3231 Reword to avoid "@code{...}'s" and the like, since it's ugly
3232 with Emacs info mode. discontents -> woes.
3233 Put a few "will"s back. time stamp -> timestamp.
3234 side-effect -> side effect.
3236 2006-06-14 Paul Eggert <eggert@cs.ucla.edu>
3238 * doc/autoconf.texi (Initializing configure, Shell Substitutions):
3239 Warn about $@ not persisting. Problem reported by Julien Danjou in
3240 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=372179>.
3241 (Special Chars in Names): Renamed from Leading _ in Macro Names.
3242 Mention other special chars, too.
3244 2006-06-14 Eric Blake <ebb9@byu.net>
3246 * doc/autoconf.texi (The Make Macro MAKEFLAGS): New node.
3248 2006-06-13 Paul Eggert <eggert@cs.ucla.edu>
3250 * doc/autoconf.texi: Some systematic minor improvements, as
3251 follows. Use "makefile" when talking about makefiles
3252 generally (which might be named "makefile" or "Makefile" or even
3253 "foo.mk"), "Makefile" when talking about a specific makefile
3254 called "Makefile". This unclutters the text from weird quotes
3255 (e.g., "`Makefile's" in info mode). Similarly, use "@var{foo}
3256 values" rather than "@var{foo}s" and similar constructs containing
3257 "}s". Use "Make rules" rather than "Makefile rules". Minor
3258 English-language improvements. Change the prefix "sub-" to "sub"
3259 and "re-" to "re".
3260 Put blank lines around examples more consistently.
3261 Avoid "rather" and "very" as intensifiers.
3262 Avoid "will" as an auxiliary.
3263 (Limitations of Make): Split this node into....
3264 (Portable Make, $< in Ordinary Make Rules, Failure in Make Rules):
3265 (Leading _ in Macro Names, Backslash-Newline-Newline):
3266 (Backslash-Newline Comments, Long Lines in Makefiles):
3267 (Macros and Submakes, The Make Macro SHELL, Comments in Make Rules):
3268 (obj/ and Make, make -k Status, VPATH and Make):
3269 (VPATH and Double-colon, $< in Explicit Rules):
3270 (Automatic Rule Rewriting, OSF/Tru64 Directory Magic):
3271 (Make Target Lookup, Single Suffix Rules, Timestamps and Make):
3272 New nodes, resulting from splitup of Limitations of Make.
3273 All cross-references changed. Raise the top node from
3274 a section to a chapter, and all subnodes accordingly.
3275 Redo the introductory wording to match the new organization.
3276 (Installation Directory Variables): Use an example that is
3277 closer to what Autoconf actually does. Mention that VPATH's
3278 value should not contain metacharacters or white space.
3279 (Fortran Compiler): Fix a VPATH bug in an example.
3280 (Leading _ in Macro Names): Mention that this problem is no longer
3281 of practical concern.
3282 (VPATH and Make): Reword the advice to make it clearer
3283 that Autoconf and Automake support VPATH in non-GNU make, but
3284 many packages have bugs in this area.
3285 ($< in Explicit Rules): Refer to Build Directories rather
3286 than using a (non-VPATH-safe) example.
3287 (Automatic Rule Rewriting): Mention the sort of disaster that
3288 can ensue with Solaris-style rule rewriting with VPATH.
3290 2006-06-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3292 * doc/install.texi (Compilers and Options): Weaken the
3293 suggestion to use GNU make for VPATH builds.

3298 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Fix M4 quotation
3299 in regular expression.
3301 2006-06-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3303 * doc/autoconf.texi (Installation Directory Variables):
3304 Drop extra @samp from `@table @samp' item.
3305 (Limitations of Usual Tools): Comment fix.
3306 Do not nest @samp just to point to other table items.
3307 (Writing testsuite.at) <AT_CHECK>: The second argument to
3308 `@dvar' is already @samp'ed.
3309 (Making testsuite Scripts) <AC_CONFIG_TESTDIR>: Likewise,
3310 do not use @var in the second argument.
3312 2006-06-07 Paul Eggert <eggert@cs.ucla.edu>
3314 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Look for
3315 $as_shell.exe too. Problem reported by Andreas Buening in
3316 <http://lists.gnu.org/archive/html/autoconf/2006-06/msg00038.html>.
3318 2006-06-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3320 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA): Work around
3321 `unused variable' compiler warning, for `-Wall -Werror'.
3322 Reported by Jaap Haitsma in
3323 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00012.html>.
3325 2006-06-06 Paul Eggert <eggert@cs.ucla.edu>
3327 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Remove core file, in
3328 case the compiler dumps core. Problem reported for
3329 OpenServer 5.0.7 by Tim Rice in
3330 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00019.html>.
3331 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE):
3332 Likewise.
3334 2006-06-06 Tim Rice <tim@multitalents.net>.
3336 * lib/freeze.mk: Quiet check-forbidden-patterns so the string
3337 "ERROR" only shows up in "make check" output if there is an
3338 error.
3340 2006-06-06 Eric Blake <ebb9@byu.net>
3342 * tests/tools.at (automatically allowed tokens): Fix typo.
3344 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
3346 * NEWS: Don't blame non-GNU VPATH compatibility issues on Automake.
3348 * doc/autoconf.texi (Integer Overflow): Mention that INT_MIN % -1
3349 typically overflows on x86 CPUs, even though the C standard
3350 requires otherwise.
3352 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3354 * configure.ac (AC_INIT): Bump to 2.59e.
3355 * NEWS: Update.
3357 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3359 Version 2.59d.
3361 * config/texinfo.tex: Sync from upstream.
3363 * bin/autoreconf.in: Trace `LT_CONFIG_LTDL_DIR'; if it has been
3364 seen, invoke libtoolize with `--ltdl' argument.
3365 * lib/autom4te.in (Autoreconf-preselections): Adjust.
3366 * NEWS: Update.
3367 Suggested by Eric Blake.
3369 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
3371 * NEWS: Whoops! AC_FUNC_STRNLEN isn't obsolescent. Problem
3372 reported by Ralf Wildenhues.

3381 * doc/autoconf.texi: Modernize some of the references to Solaris.
3383 2006-06-05 Stepan Kasal <kasal@ucw.cz>
3385 * lib/m4sugar/m4sugar.m4 (m4_require): Modify the error
3386 message issued by AC_REQUIRE.
3387 * tests/m4sugar.at: Check m4_require's error message.
3388 * tests/base.at: Check AC_REQUIRE's error message.
3389 * tests/local.at (AT_CHECK_M4): New macro, almost identical
3390 to...
3391 (AT_CHECK_AUTOM4TE): ... which is now a thin wrapper around
3392 AT_CHECK_M4.
3393 (AT_CHECK_AUTOCONF): Use AT_CHECK_M4; no longer support
3394 `expout' as the last parameter.
3395 * tests/tools.at: Adapt to the above change.
3397 2006-06-04 Stepan Kasal <kasal@ucw.cz>
3399 * doc/autoconf.texi (Limitations of Usual Tools): Correct
3400 information about race-free implementations of mkdir.

3407 * doc/autoconf.texi (autom4te Invocation): Likewise.
3409 2006-06-04 Paul Eggert <eggert@cs.ucla.edu>
3411 * NEWS: GNU make now recommended for VPATH builds.
3412 Mention that some macros are now documented to be obsolescent.
3413 * doc/autoconf.texi:
3414 Prefer "current" to "modern" to describe
3415 currently-used (albeit perhaps old-fashioned) hosts.
3416 Mention which ancient features no longer need to be worried about.
3417 setgid -> set-group-ID
3418 setuid -> set-user-ID (these are the Posix terms)
3419 Fix some misuses of "only".
3420 (AC_C_BACKSLASH_A, AC_C_CONST, AC_C_PROTOTYPES):
3421 (AC_C_STRINGIZE, AC_C_VOLATILE, AC_FUNC_CLOSEDIR_VOID):
3422 (AC_FUNC_GETPGRP, AC_FUNC_LSTAT, AC_FUNC_MEMCMP):
3423 (AC_FUNC_SELECT_ARGTYPES, AC_FUNC_SETPGRP):
3424 (AC_FUNC_SETVBUF_REVERSED, AC_FUNC_STAT, AC_FUNC_STRFTIME):

3427 (AC_HEADER_SYS_WAIT, AC_HEADER_TIME, AC_ISC_POSIX):
3428 (AC_PROG_GCC_TRADITIONAL, AC_STRUCT_TM):
3429 Mention that these macros are obsolescent.
3430 (Installation Directory Variables): shall -> should
3431 (File Descriptors): Mention that 0, 1, 2 might get reopened.
3432 Mention that it's now safe to use 3 and 4.
3433 (Limitations of Usual Tools): cp -r is now specified by Posix.
3434 Omit longwinded and obsolescent discussion of cp -f.
3435 Modernize discussion of expr, ls.
3436 (Limitations of Make): Modernize discussion of VPATH builds.
3437 Mention $? as a workaround in some cases.
3438 * doc/install.texi (Basic Installation):
3439 Mention "./configure; make; make install" first. Be more
3440 specific about why this file is generic. Remove unnecessary
3441 parens. Remove misleading "only". Remove obsolete advice
3442 about csh. Don't say "configure" takes awhile; say it
3443 might take a while. Suggest CFLAGS=-g rather than CFLAGS=-O2,
3444 and CC=c99 rather than CC=c89, as these are blessed by current
3445 Posix. Recommend GNU make if doing a VPATH build.
3447 2006-06-03 Paul Eggert <eggert@cs.ucla.edu>
3449 * doc/autoconf.texi: Use a consistent style "$ @kbd{...}" for
3450 examples involving shell prompts.
3452 2006-06-02 Stepan Kasal <kasal@ucw.cz>
3453 and Paul Eggert <eggert@cs.ucla.edu>
3455 * doc/autoconf.texi (Here-Documents): Add details about the
3456 pre-ksh93g bug. Reword slightly to make it clearer. Consistently
3457 use "here-documents" instead of "here documents".
3459 2006-06-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3461 * config/texinfo.tex, doc/standards.texi: Sync from upstream.
3463 2006-06-01 Paul Eggert <eggert@cs.ucla.edu>
3465 * doc/autoconf.texi (File System Conventions): Warn about ":"
3466 anywhere in directory names.
3468 2006-05-31 Paul Eggert <eggert@cs.ucla.edu>
3470 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be even more conservative
3471 about quoting the case statement, just in case.
3472 * doc/autoconf.texi (Here-Documents): Mention that the ksh bug
3473 was fixed in ksh93g; reported by Ralf Wildenhues.
3475 2006-05-31 Stepan Kasal <kasal@ucw.cz>
3477 * doc/autoconf.texi (System Services): Do not document
3478 overriding EXEEXT via ac_cv_exeext=ext.
3479 (Particular Programs) <AC_PROG_MKDIR_P>:
3480 Document that ${MKDIR_P} understands --.
3481 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Improve the
3482 comment.
3484 2006-05-31 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3486 * lib/m4sugar/m4sh.m4 (_AS_DIRNAME_PREPARE): Guard against test
3487 argument with leading hyphen. Problem reported by Paul Eggert.
3489 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
3491 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be more conservative
3492 about quoting ac_try: quote all of it, if any of it seems suspicious.
3493 This means we don't have to worry about ${ or sed any more.
3494 Also, double-quote the case statement, to work around misuses via
3495 underquoting as reported by Ralf Wildenhues in
3496 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00169.html>.
3497 (_AC_EVAL_STDERR): Revert, since evidently some packages rely on this
3498 undocumented and dangerous macro.
3499 Problem reported by Ralf Wildenhues in
3500 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00168.html>.
3502 2006-05-31 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3504 * lib/m4sugar/m4sh.m4 (_AS_DIRNAME_PREPARE): Check whether
3505 `dirname -- /' returns `/', for SunOS dirname scripts that escaped.
3506 Report by Sam Sirlin <sam@kalessin.jpl.nasa.gov>.
3508 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
3510 * lib/autoconf/general.m4: Revert AC_TRY_EVAL and AC_TRY_COMMAND,
3511 since evidently some packages rely on the old, broken behavior.
3512 Problem reported by Ralf Wildenhues in
3513 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00160.html>.
3514 (AC_TRY_EVAL, AC_TRY_COMMAND, _AC_EVAL): Go back to the
3515 pre-2006-05-26 definitions, but leave in the comments that
3516 these macros are dangerous and should not be used.
3517 (_AC_DO_ECHO): Renamed from _AC_EVAL_ECHO. All callers changed.
3518 (_AC_DO): Renamed from _AC_EVAL. All callers changed.
3519 (_AC_DO_STDERR): Renamed from _AC_EVAL_STDERR. All callers changed.
3520 (_AC_DO_VAR): Renamed from AC_TRY_EVAL.
3521 (_AC_DO_TOKENS): Renamed from AC_TRY_COMMAND.
3523 2006-05-29 Paul Eggert <eggert@cs.ucla.edu>
3525 * lib/autoconf/status.m4 (AC_OUTPUT_MAKE_DEFS): Rewrite to avoid
3526 the use of 'tr', since this is our only use of 'tr'.
3528 2006-05-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3529 and Paul Eggert <eggert@cs.ucla.edu>
3531 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE):
3532 Don't assume 'grep' works on long lines, since AIX grep doesn't.
3534 2005-05-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3536 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Do not use `grep' on
3537 the output file in the `${datarootdir}' test.
3539 2005-05-28 Stepan Kasal <kasal@ucw.cz>
3540 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3542 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If we have not seen
3543 mention of `datarootdir' in the input file(s), but literal
3544 `${datarootdir}' in the output file, and we haven't warned yet,
3545 then warn as well: the user may have (erroneously) used
3546 `AC_SUBST([mydatadir], [$datadir/my])' instead of the correct
3547 `AC_SUBST([mydatadir], ['${datadir}/my'])'.
3548 * tests/torture.at (datarootdir workaround): Extend this test.
3549 * NEWS: Update.
3551 2006-05-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3552 and Paul Eggert <eggert@cs.ucla.edu>
3554 * doc/autoconf.texi (autoheader Invocation): The first argument to
3555 `AC_DEFINE_UNQUOTED' need not be a literal. Mention the
3556 alternatives and clear up the language a bit.
3558 2006-05-27 Paul Eggert <eggert@cs.ucla.edu>
3560 * NEWS: Reword notice for AC_TRY_COMMAND, AC_TRY_EVAL,
3561 ac_config_guess, ac_config_sub, ac_configure.
3562 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
3563 Fix typo that prevented an unnecessary space from being removed.
3564 Problems reported by Ralf Wildenhues in:
3565 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00143.html
3567 2006-05-26 Paul Eggert <eggert@cs.ucla.edu>
3569 * doc/autoconf.texi (Particular Programs, Limitations of Usual Tools):
3570 Use better wording to talk about AC_PROG_MKDIR_P's thread-safety.
3571 Don't use the term "thread-safe" to talk about mkdir race
3572 conditions, since the problem is more a process than a thread
3573 issue. Problem reported by Stepan Kasal in:
3574 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00088.html
3575 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Use code that mimics
3576 the test for 'install' more closely. Look at MKDIR_P first.
3577 Look in the PATH, and at /opt/sfw/bin.
3578 Look for a 'gmkdir' program as well (Solaris 10 /opt/sfw/bin/gmkdir).
3579 Don't bother to try mkdir -p, since we already check mkdir --version;
3580 just look at the version number. (There's no easy way to check
3581 for race-free implementations.)
3582 * tests/tools.at (autoconf: subdirectories): Adjust to above
3583 changes, since MKDIR_P now might end in "/mkdir -p".
3585 * doc/autoconf.texi (autoheader Invocation): Mention that the
3586 first arg of AC_DEFINE_UNQUOTED must be a literal.
3587 Problem reported by Ben Pfaff in
3588 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00090.html>.
3590 * NEWS: Mention that AC_TRY_COMMAND and AC_TRY_EVAL may be removed.
3591 * doc/autoconf.texi (Special Chars in Variables): New section.
3592 (Preset Output Variables): Warn about special chars in CPPFLAGS.
3593 (Installation Directory Variables): Quote $(datadir) better.
3594 (Limitations of Builtins): Describe some of eval's trickiness.
3596 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Simplify quoting.
3597 * lib/autoconf/fortram.m4 (_AC_PROG_FC_V_OUTPUT): Likewise.
3598 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Put leading space
3599 in front of every arg, not just trailing args. Quote apostrophes.
3600 (_AC_EVAL_ECHO): New macro.
3601 (_AC_EVAL, AC_EVAL_STDERR): Use it. Quote arg of eval.
3602 (AC_TRY_EVAL, AC_TRY_COMMAND): Mention that these macros might get
3603 removed.
3604 (_AC_LINK_IFELSE): Use proper rule for shell continuation lines,
3605 exposed by quoting of eval argument. Put the command on line line
3606 so it logs better.
3607 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): Use eval more safely.
3608 (_AC_PATH_X, AC_PATH_X): Quote more safely.
3609 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Use eval more safely.
3610 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Don't use eval.
3611 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Minor style change.
3612 Handle special chars in prefix, ac_srcdir, ac_aux_dir.
3613 Use eval more safely.
3614 (_AC_OUTPUT_CONFIG_STATUS): Adjust to above changes.
3615 * lib/m4sugar/m4sh.m4 (AS_VAR_GET): Note that this API needs
3616 to be replaced.
3617 * tests/base.at (AC_TRY_COMMAND): Use proper rule for shell continuation
3618 lines, exposed by quoting of eval argument.
3620 2006-05-26 Stepan Kasal <kasal@ucw.cz>
3621 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3623 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Drop the
3624 initialization of `ac_cv_exeext', do not override it if it was
3625 already set, unless it was set to `no', for compatibility with
3626 Autoconf-2.13, and comment this.
3627 Do not export `ac_cv_exeext', Libtool hasn't needed this for years.
3628 (_AC_COMPILER_EXEEXT_DEFAULT): Likewise, do not export it.
3629 (_AC_COMPILER_EXEEXT_WORKS, _AC_COMPILER_EXEEXT_CROSS): Typos.
3630 * doc/autoconf.texi (Compilers and Preprocessors) <EXEEXT>:
3631 Document that this test may be overridden by setting
3632 `ac_cv_exeext'.
3634 2006-05-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3636 Revert these two patches:
3638 2006-04-06 Eric Blake <ebb9@byu.net>
3639 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_O): Inside cache
3640 check, s/ac_exeext/ac_cv_exeext/. Fixes regression introduced
3641 2006-04-01.
3643 2006-04-01 Stepan Kasal <kasal@ucw.cz>
3644 Clean up _AC_COMPILER_EXEEXT* macros.
3645 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't try to
3646 detect exeext, it will be done by _AC_COMPILER_EXEEXT_O; just set
3647 ac_file to the name of the default output file and call
3648 _AC_COMPILER_EXEEXT_WORKS. Move the definition of ac_files and the
3649 initial `rm' of the candidate files...
3650 (_AC_COMPILER_EXEEXT): ... here and simplify them. Moreover, use
3651 the same list in subsequent `rm' calls, and for the temporary
3652 redefinition of ac_clean_files; call _AC_COMPILER_OBJEXT at the end,
3653 and don't call the other _AC_COMPILER_EXEEXT_* macros directly, use...
3654 (_AC_COMPILER_EXEEXT_TESTS): ... this new macro.
3655 (_AC_COMPILER_EXEEXT_O): Don't export ac_cv_exeext, it's not needed (or
3656 no longer needed) by libtool. Make it a cache check.
3657 (_AC_COMPILER_EXEEXT_CROSS): Remove the comment, it was obviously
3658 copied here by mistake.
3659 (AC_NO_EXECUTABLES): Redefine _AC_COMPILER_EXEEXT_TESTS, not
3660 _AC_COMPILER_EXEEXT.
3661 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX, AC_PROG_OBJC): Do not call
3662 _AC_COMPILER_OBJEXT directly.
3663 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
3665 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3667 * doc/autoconf.texi (Limitations of Usual Tools) < sed (`t')>:
3668 Fix description of how the buggy `sed' works.
3670 2006-05-25 Noah Misch <noah@cs.caltech.edu>
3672 Sync from Automake:
3674 * lib/Autom4te/XFile.pm (lock): Allow EOPNOTSUPP, besides
3675 ENOLCK. Only mention `make -j' when applicable. Only raise
3676 fatal errors when `make -j' is involved. Improve error message.
3678 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3680 * doc/autoconf.texi (Here-Documents): We now know more about
3681 the variable expansion in here documents bug.
3682 Thanks to Tim Rice and Stepan Kasal.
3684 * doc/autoconf.texi (Making testsuite Scripts): Add an example
3685 how to use TESTSUITEFLAGS. Suggested by Eric Blake.
3687 2006-05-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3689 * tests/autotest.at (Multiline command from M4 expansion):
3690 No failure to be expected if the shell quotes newlines in
3691 commands in the `set -x' output. Report by Tim Rice.
3692 * THANKS: Update.
3694 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
3696 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Don't use shell
3697 expansion in the here-documents used by config.status, as that
3698 runs afoul of the Korn shell version M-12/28/93d bug described in
3699 the Autoconf manual, and this in turn causes a Coreutils 5.95 build to
3700 fail as described by Tim Rice and diagnosed by Ralf Wildenhues in
3701 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00082.html>.
3703 2006-05-23 Jim Meyering <jim@meyering.net>
3705 * lib/autoconf/functions.m4 (AC_FUNC_LSTAT_FOLLOWS_SLASHED_SYMLINK):
3706 Fix typo introduced with 2006-04-02 change. It reversed the sense
3707 of the test.
3709 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
3711 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Simplify ac_dA and
3712 ac_dB slightly, to save bytes in the script.
3713 Max out at 50 lines, rather than 96; this is more likely
3714 (though not guaranteed) to avoid obscure 'sed' failures.
3716 2006-05-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3718 * lib/autotest/general.m4 (AT_INIT): UnixWare `tr' may interpret
3719 `tr -d -' as bad option argument. Work around this by deleting
3720 an unrelated character.
3721 Report by Tim Rice <tim@multitalents.net>.
3723 2006-05-22 Paul Eggert <eggert@cs.ucla.edu>,
3724 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
3725 Stepan Kasal <kasal@ucw.cz>
3727 * doc/autoconf.texi (Particular Programs): Do not promise that
3728 we always prefer the GNU version of the program, and that we
3729 search according to PATH; both rules can have exceptions.
3730 Update description of AC_PROG_GREP, AC_PROG_EGREP, AC_PROG_FGREP,
3731 AC_PROG_SED. Move descriptions of limitations
3732 to the Limitations of Usual Tools section.
3733 (Limitations of Usual Tools) <sed>: Mention script length
3734 limitations with Solaris /usr/ucb/sed.
3735 <grep>: Fix wording for empty alternative. Mention that -c and
3736 -l should not be combined, and that -E and -F should not be
3737 combined.
3739 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
3740 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3742 * lib/autoconf/programs.m4 (AC_PROG_SED): Catch script length
3743 limits in Solaris 8 /usr/ucb/sed by testing a long script.
3745 2006-05-22 Stepan Kasal <kasal@ucw.cz>
3747 * doc/autoconf.texi (Defining Symbols): Literal parameter of
3748 AC_DEFINE is now passed to m4_pattern_allow.
3749 * NEWS: Mention that; likewise for AC_SUBST.
3750 * lib/autoconf/general.m4 (AC_DEFINE_TRACE_LITERAL): Pass
3751 the parameter to m4_pattern_allow.
3752 * tests/tools.at: Add a check for that.
3754 2006-05-22 Stepan Kasal <kasal@ucw.cz>
3756 * lib/autoconf/status.m4: Fix typos.
3758 2006-05-21 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3760 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Remove
3761 only the files that this macro generates.
3763 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
3765 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: For
3766 the HP-UX sed limitation of 99 commands, labels do not count.
3767 * lib/autoconf/status.m4 (_AC_SED_CMD_LIMIT): Mention that
3768 in the comment.
3769 (_AC_OUTPUT_HEADER): Revert the change from 2006-05-19.
3771 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
3773 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT):
3774 Import the following fix from coreutils:
3776 2006-01-13 Jim Meyering <jim@meyering.net>
3778 Invoke AC_CHECK_FUNCS(getmntent) unconditionally so that tests of
3779 $ac_cv_func_getmntent (e.g., in gl_LIST_MOUNTED_FILE_SYSTEMS) need
3780 not double-quote uses of that variable, to accommodate the rare
3781 case in which getmntent is available in none of the libraries
3782 checked. This happens at least on FreeBSD 5.0.
3784 2006-05-20 Paul Eggert <eggert@cs.ucla.edu>
3786 * lib/autoconf/general.m4 (AC_CONFIG_AUX_DIRS): Bring back
3787 ac_config_guess, ac_config_sub, and ac_configure, since evidently
3788 some other programs unwisely rely on these undocumented vars.
3789 But put in warning comments about them.
3790 Problem reported by Ralf Wildenhues in
3791 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00068.html>.
3792 * NEWS: Document that these variables are intended to go away.
3794 2006-05-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3796 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): Require AC_PROG_CXX,
3797 and set the language to C++ (analogous to the equivalent Fortran
3798 tests).
3800 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): New macro.
3801 * doc/autoconf.texi (C++ Compiler): Document it.
3802 * lib/autoconf/fortran.m4 (_AC_PROG_FC_C_O): Adjust comment.
3803 * NEWS: Update.
3805 2006-05-19 Paul Eggert <eggert@cs.ucla.edu>
3807 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Fix off-by-one bug
3808 that caused config.status to generate 100-command sed scripts; the
3809 portable limit is 99.
3811 2006-05-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3813 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Name temporary
3814 variable `ac_d' instead of `d' to avoid infringing namespace.
3815 Report by Ralf Menzel.
3817 2006-05-18 Paul Eggert <eggert@cs.ucla.edu>
3819 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Don't prepend
3820 $ac_top_build_prefix to $MKDIR_P if it's just 'mkdir -p'.
3821 * tests/tools.at (autoconf: subdirectories): New test, taken from
3822 the corresponding problem report by Ralf Wildenhues in:
3823 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00053.html
3825 * lib/autoconf/functions.m4 (AC_REPLACE_FNMATCH, AC_FUNC_FNMATCH_GNU):
3826 Quote some uses of shell variables if they might suffer unexpected
3827 globbing. This doesn't fix all instances of quoting problems that
3828 I found, just the easy ones that look safe.
3829 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR, _AC_INIT_HELP):
3830 (AC_CONFIG_AUX_DIR, AC_CONFIG_AUX_DIR_DEFAULT, AC_CONFIG_AUX_DIRS):
3831 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST, AC_CANONICAL_TARGET):
3832 (AC_CACHE_LOAD, AC_CACHE_SAVE): Likewise.
3833 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF, _AC_PATH_X_DIRECT): Likewise.
3834 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Likewise.
3835 * lib/autoconf/status.m4 (_AC_OUTPUT_LINK, _AC_OUTPUT_SUBDIRS):
3836 Likewise.
3837 * lib/autotest/general.m4 (_AC_INIT_PARSE_ARGS): Likewise.
3838 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Likewise.
3840 2006-05-18 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3842 * bin/autoreconf.in ($help): Reword according to the manual.
3843 Suggested by Olly Betts.
3845 2006-05-17 Olly Betts <olly@survex.com> (tiny change)
3846 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3848 * bin/autoreconf.in: Pass the directory argument to
3849 `require_configure_ac'. Fix comment.
3850 * tests/torture.at (Configuring subdirectories): Expose this.
3851 Reported by Olly Betts.
3853 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3855 * lib/Automake/Configure_ac.pm, lib/Automake/Channels.pm,
3856 lib/Automake/FileUtils.pm, lib/Automake/Struct.pm: Sync from
3857 Automake as follows:
3859 * lib/Autom4te/Configure_ac.pm (find_configure_ac): Use
3860 `$configure_in' instead of `configure.in', to preserve
3861 directory component.
3863 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3865 * config/config.guess, config/config.sub, config/texinfo.tex,
3866 doc/make-stds.texi, doc/standards.texi: Sync from upstream.
3868 2006-05-14 Paul Eggert <eggert@cs.ucla.edu>
3870 * lib/autoconf/headers.m4 (AC_HEADER_STDBOOL): Fix overly-picky
3871 test for C99 conformance; (bool) 0.5 is an integer constant
3872 expression, but (bool) -0.5 is not. Problem reported by Fedor
3873 Sergeev in <http://forum.sun.com/jive/thread.jspa?threadID=96202>.
3875 2006-05-13 Paul Eggert <eggert@cs.ucla.edu>
3877 * doc/autoconf.texi (Particular Programs): AC_PROG_MKDIR_P now
3878 sets MKDIR_P, not mkdir_p, to avoid collisions with Automake.
3879 Warn about obsolete install-sh files. Remove stray sentence
3880 fragment and fix cross reference.
3881 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Don't insist on
3882 install -d; this undoes the 2006-05-10 change.
3883 (MKDIR_P): Mark with AN_MAKEVAR.
3884 (AC_PROG_MKDIR_P): Fall back on $ac_install_sh, not $INSTALL, so
3885 that we don't require $INSTALL to be thread-safe. Move comments
3886 out of generated code. Require AC_CONFIG_AUX_DIR_DEFAULT instead
3887 of AC_PROG_INSTALL. Output a message saying that we're checking
3888 mkdir -p. Set MKDIR_P rather than mkdir_p. Do special magic for
3889 MKDIR_P instead of AC_SUBST.
3890 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE, _AC_OUTPUT_CONFIG_STATUS):
3891 Special magic for MKDIR_P, too.
3892 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Remove comment that defeated
3893 a dnl.
3894 * tests/local.at (AT_CHECK_ENV): mkdir_p -> MKDIR_P.
3896 2006-05-11 Paul Eggert <eggert@cs.ucla.edu>
3898 Sync from Automake, as follows:
3900 2006-05-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3901 * config/install-sh: Initialize IFS, so field splitting isn't
3902 turned off later.
3903 * config/mkinstalldirs: Likewise.
3904 * config/missing: Remove superfluous quotes. Replace all uses of
3905 `[' by `test', for consistency, and for..
3906 * config/missing (sed_minuso, sed_output): New variables.
3907 (autom4te, help2man, makeinfo): Use them. Unifies detection of
3908 `-o FILE', `--output FILE', `--output=FILE', stricter regex.
3909 Fixes `missing' to detect `--output' for help2man. Fixes
3910 PR automake/483. Report by Dennis J. Linse.
3911 (autom4te): Document in `missing --help'.
3913 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
3915 * NEWS: New macro AC_PROG_MKDIR_P. AS_MKDIR_P is now more robust.
3916 * config/install-sh: Don't use 'path' to talk about file names,
3917 as per GNU coding standards. Close a race condition reported by Ralf
3918 Wildenhues and Stepan Kasal. There is still a race condition
3919 on hosts that predate Posix 1003.1-1992, but we can't help this.
3920 Don't mishandle weird characters like space on pre-Posix hosts.
3921 Invoke mkdir at most once per dir arg on pre-Posix hosts.
3922 * doc/autoconf.texi (Programming in M4sh): Cross-reference to
3923 AC_PROG_MKDIR_P from AS_MKDIR_P.
3924 (Limitations of Usual Tools): Cross-reference to AC_PROG_MKDIR_P
3925 from mkdir. Mention that Autoconf 2.60 install-sh is safe but
3926 earlier editions are not (including Automake 1.8.3).
3927 Do not suggest mkinstalldirs for thread-safety.
3928 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Insist on an 'install'
3929 that understands -d, so that AC_PROG_MKDIR_P can fall back on $INSTALL.
3930 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Make it more robust in the
3931 presence of special characters and race conditions.
3932 * tests/local.at (AT_CHECK_ENV): Add mkdir_p to the list of variables
3933 in Autoconf's name space.
3935 2006-05-10 Bruno Haible <bruno@clisp.org>
3936 and Paul Eggert <eggert@cs.ucla.edu>
3938 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): New macro, taken
3939 from Automake with minor changes.
3940 * doc/autoconf.texi (Particular Programs): Document AC_PROG_MKDIR_P.
3942 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
3944 * config/install-sh: Update to Automake CVS version, as follows:
3945 2006-04-25 Stepan Kasal <kasal@ucw.cz>
3946 * lib/install-sh: Simplify the expr implementation of dirname.
3947 2006-04-24 Paul Eggert <eggert@cs.ucla.edu>
3948 * lib/install-sh: Handle --, and diagnose unknown options.
3950 2006-05-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3952 * tests/Makefile.am (AUTOTEST): Use `$(MY_AUTOM4TE)' instead of
3953 `./autom4te' to create `./testsuite', since the `all' target
3954 will ensure its presence, but `installcheck' should not create
3955 the uninstalled wrappers.
3957 * tests/torture.at (Unusual Automake input files): Skip if we
3958 detect automake < 1.8.
3960 2006-05-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3962 * lib/autoconf/c.m4 (AC_PROG_CC_STDC): If ac_cv_prog_cc_stdc
3963 is set to `no', then that overrides and sets ac_cv_prog_cc_c89
3964 and ac_cv_prog_cc_c99 to `no', for backward compatibility.
3965 * NEWS: Update.
3967 2006-05-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3969 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Take care not to
3970 munge (multiple) white space and other oddities.
3971 * tests/torture.at (AT_CHECK_AC_ARG_VAR): Make sure to M4-escape
3972 single quotes in variable assignment.
3973 (AC_ARG_VAR, configure invocation): Adjust tests to expose this
3974 and similar failures by adding multiple spaces, tabs, and other
3975 special characters.
3976 Report and different test suggested by Francesco Romani
3977 <fromani@gmail.com> and Andrew Church <achurch@achurch.org>.
3979 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): When we escape
3980 single quotes, we only need to search for single quotes; this
3981 both simplifies the search pattern, and makes us less
3982 susceptible to `echo' variations for arguments not containing
3983 single quotes.
3984 (_AC_ARG_VAR_VALIDATE): Likewise.
3986 2006-05-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3988 * doc/autoconf.texi (Special Shell Variables) <IFS>: Document
3989 `$*' and IFS concatenation issue with traditional shells and
3990 bash-2.04. Report by Seanster@Seanster.com.
3992 2006-05-03 Bruno Haible <bruno@clisp.org>
3994 * doc/autoconf.texi (Limitations of Usual Tools): Identify more
3995 precisely which Mac OS X versions have the od problem.
3997 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
3999 * doc/autoconf.texi: Use @option systematically.
4001 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
4002 and Bruno Haible <bruno@clisp.org>
4004 * doc/autoconf.texi (Limitations of Usual Tools): Add a paragraph
4005 about 'od'.
4006 (Integer Overflow): Mention the special case of integer division
4007 overflow.
4009 2006-05-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4011 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Cater for
4012 traditional shells like the Solaris one that do not use the
4013 first IFS character for assembling `$*'.
4014 Prompted by a related report from autoconf_bug@nro.ca.
4016 2006-05-01 Paul Eggert <eggert@cs.ucla.edu>
4017 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4019 * doc/autoconf.texi (Limitations of Builtins, Limitations of Make):
4020 Mention more problems with the -e option.
4022 2006-04-30 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4024 * NEWS: Typo.
4025 * doc/autoconf.texi (Systemology): Mention the Heirloom Project.
4027 * doc/autoconf.texi (Introduction, Pointers): Use `@/' liberally
4028 in URLs to improve DVI formatted output (requires texinfo 4.6).
4029 (System Services, Systemology, Shellology): Likewise.
4030 (Limitations of Usual Tools): Rewrite Mac OS X example for nicer
4031 output.
4033 * doc/autoconf.texi (Fortran Compiler): Do not use `@ovar' in
4034 continuous text.
4035 (Runtime): Fix macro argument names to match description:
4036 `action-if-found' -> `action-if-true' and similarly.
4037 (Obsolete Macros): Likewise.
4038 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE): Likewise.
4039 (AC_COMPILE_IFELSE, AC_TRY_COMPILE, _AC_LINK_IFELSE)
4040 (AC_LINK_IFELSE, AC_TRY_LINK, AC_COMPILE_CHECK): Likewise.
4042 2006-04-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4044 * doc/autoconf.texi (Limitations of Make): Clean up markup.
4046 * ChangeLog: Typo.
4047 * doc/autoconf.texi (Portable Shell): Allow wrapped URLs, for
4048 DVI output.

4059 * doc/autoconf.texi (Portable C and C++, Varieties of Unportability):
4060 (Integer Overflow, Null Pointers, Buffer Overruns):
4061 (Floating Point Portability, Exiting Portably): New sections.
4062 (Writing Test Programs): Fix some langauge. Recommend exiting
4063 with status 1, not merely nonzero. Clarify exit declaration.
4064 (Run Time): Move C exit status stuff to new Exiting Portably section.
4065 (Systemology): Mention Posix and levenez. Update v7 reference.
4066 (Portable Shell): Mention the Posix shell.
4068 2006-04-25 Stepan Kasal <kasal@ucw.cz>
4070 * bin/autoconf.as (me): Replace by as_me.
4072 2006-04-25 Paul Eggert <eggert@cs.ucla.edu>
4074 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Don't use AS_ERROR,
4075 since as_me isn't set yet.
4077 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
4079 Prepare for deprecation of AS_BASENAME and AS_DIRNAME, and fix
4080 a few minor bugs in this area.
4082 * doc/autoconf.texi (Programming in M4sh): Comment out the
4083 documentation of AS_BASENAME, for now.
4084 (Shell Substitutions): Do not use AS_DIRNAME in an example.

4096 (_AS_BASENAME_SED): Renamed from AS_BASENAME_SED. All uses changed.
4097 (_AS_BASENAME_PREPARE): Reject implementations that cannot handle "--".
4098 (_AS_DIRNAME_PREPARE): Likewise.
4099 (_AS_DIRNAME_EXPR): Renamed from AS_DIRNAME_EXPR. All uses changed.
4100 (_AS_DIRNAME_SED): Renamed from AS_DIRNAME_SED. All uses changed.
4101 (AS_DIRNAME): Use "dirname --".
4103 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>

4113 with more accuracy and detail.
4115 2006-04-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4117 * doc/autoconf.texi (Introduction): The GNU Autoconf Macro
4118 Archive is not officially `GNU' any more. Update URL.
4119 (Defining Directories): Likewise
4120 * lib/autoconf/c.m4 (AC_C_RESTRICT): Update URL.
4122 2006-04-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4124 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Remove the leading
4125 newline from the `trap' code to finish `config.log'; the NetBSD
4126 /bin/sh resets the exit status after an empty command, as
4127 documented in doc/autoconf.texi.
4128 Reported by Dalibor Topic <robilad@kaffe.org>.
4130 2006-04-19 Paul Eggert <eggert@cs.ucla.edu>
4132 * doc/autoconf.texi (C Compiler): Clarify AC_C_TYPEOF.
4133 Suggested by Bruno Haible.

4137 * configure.ac (ac_cv_sh_n_works): Don't try to test for it, since
4138 some shells (e.g., Solaris 8 /bin/sh) implement it verrrry slowly.
4139 Instead, just list the shells that we know work.
4140 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Remove 2nd arg. All uses
4141 changed. Be more cautious about the _cv_ variable.
4142 * tests/tools.at (Syntax of the shell scripts): Check the
4143 _cv_ variable once, at first, to avoid an internal autoconf error
4144 when sh -n does not work.
4146 2006-04-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4148 * lib/Autom4te/FileUtils.pm: Sync from Automake.
4150 2006-04-16 Paul Eggert <eggert@cs.ucla.edu>
4152 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Don't
4153 use ">&-" since we're only 99.999% sure that this is portable,
4154 and since the MinGW bug is fixed in a different way.
4155 * lib/autotest/general.m4 (AT_INIT): Likewise.
4157 2006-04-16 Stepan Kasal <kasal@ucw.cz>
4159 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Handle --recheck
4160 before opening config.log, to avoid hitting a bug on MinGW.
4162 2006-04-14 Paul Eggert <eggert@cs.ucla.edu>
4164 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Close
4165 AS_MESSAGE_LOG_FD before reopening it onto the log file.
4166 This works around a MinGW bug reported by Eric Paire.
4167 Make sure that all writes to the log file append to it,
4168 rather than possibly losing data.
4169 * lib/autotest/general.m4 (AT_INIT): Likewise.
4171 2006-04-14 Stepan Kasal <kasal@ucw.cz>
4173 * lib/Autom4te/FileUtils.pm (find_file): Fix a typo in the
4174 description.
4176 2006-04-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4178 * NEWS: Update.
4180 * configure.ac (AC_INIT): Bump to 2.59d.
4182 2006-04-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4184 Version 2.59c.
4186 * Makefile.maint (news-date-check): Do not require a leading `*'
4187 before the release date in NEWS.
4189 2006-04-12 Stepan Kasal <kasal@ucw.cz>
4190 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4192 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If the templates for
4193 the instantiated file do not contain the string 'datarootdir'
4194 but contain @datadir@, @docdir@, @infodir@, @localedir@, or
4195 @mandir@, replace the reference '${datarootdir}' by the value.
4196 * tests/torture.at (datarootdir workaround): New test.
4197 * NEWS: Advertise this temporary fixup.
4198 Based on a patch by Bruno Haible, reported and analyzed by
4199 Paul Eggert and Noah Misch.
4201 2006-04-12 Eric Blake <ebb9@byu.net>
4203 * tests/autotest.at (Debugging a failed test): Fix comment.
4205 2006-04-12 Stepan Kasal <kasal@ucw.cz>
4207 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): Simplify the summary of
4208 all the changes since 2006-04-07.
4210 2006-04-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4212 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): If `ln -s file1 file2'
4213 succeeded, but `ln -s file dir' failed, take care to remove the
4214 leftover target before the next test, to prevent its spurious
4215 failure; also make sure `ln file dir' works before selecting it.
4216 Thanks to Keith Marshall for pointing this out.
4217 * THANKS: Update.
4219 * lib/autotest/general.m4 (AT_INIT): Store quoted variable
4220 assignments in `at_debug_args', so that we put them correctly
4221 in the `run' script.
4222 * tests/autotest.at (Debugging a failed test): Unmark XFAIL.
4223 Reported by Eric Blake.
4225 2006-04-11 Eric Blake <ebb9@byu.net>
4227 * tests/autotest.at (AT_CHECK_AT): Add new argument, to allow
4228 top-level tests after micro-suite has been run. Used in...
4229 (Debugging a successful test, Debugging script and environment),
4230 (Debugging a failed test): ...these new tests. The first of these
4231 is fixed by...
4232 * lib/autotest/general.m4 (_AT_CREATE_DEBUGGING_SCRIPT): New
4233 macro, split out from...
4234 (AT_INIT): ...here, so that using -d also generates a run script.
4235 Document that -d inhibits top-level logging.
4236 * doc/autoconf.texi (testsuite Invocation): Document that -d only
4237 inhibits top-level logging; debug scripts are created.
4239 * lib/autotest/general.m4 (_AT_CHECK): Avoid syntax error on empty
4240 check.
4241 * tests/autotest.at (Empty test, Empty check): New test to check it.
4243 * lib/autoconf/c.m4 (AC_C_CONST, AC_C_VOLATILE): Avoid warnings
4244 from gcc.
4246 2006-04-10 Stepan Kasal <kasal@ucw.cz>
4248 * tests/mktests.sh: Use "trap '' 0", not "trap 0". Do not touch
4249 the files if a problem appears. Make the empty *.at files
4250 read-only, too. Proposed by Ralf Wildenhues.
4252 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4254 * config/Makefile.am: Add comment to force updated Makefile.in.
4256 * lib/freeze.mk: Fix typo in comment. Unlike the last, white
4257 space only patch to this file, this patch causes the Makefile.in
4258 files that include freeze.mk to be updated, and thus have a
4259 newer time stamp again, which in turn makes a pristine CVS
4260 checkout have correct time stamps.
4262 * Makefile.maint (cvs-sv): New macro, to be used..
4263 (config.guess-url_prefix, config.sub-url_prefix)
4264 (texinfo.tex-url_prefix, standards.texi-url_prefix): ..here;
4265 point to CVS text checkout of Gnulib files.
4266 (copyright-check): Bump current year.
4267 (announcement): Do not hard-wire `./announce-gen'.
4268 (cvs-update): Propagate failures of `cvs' and `move-if-change'
4269 correctly.
4270 * Makefile.cfg (executable-update): Use `chmod a+x' instead of
4271 `chmod +x'.
4272 (wget_files): Update config.guess, config.sub, texinfo.tex by
4273 `wget-update', now that their URLs work again.
4275 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
4277 * doc/autoconf.texi (Particular Types): Don't use AC_CHECK_TYPE.
4278 Problem noted by Paul D. Smith.
4280 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4282 * doc/autoconf.texi: Remove unused words from word list.
4283 * .x-sc_prohibit_atoi_atof, .x-sc_space_tab, .x-sc_sun_os_names,
4284 .x-sc_trailing_space: New files.
4286 * doc/standards.texi: Sync from gnulib.
4288 * NEWS, doc/autoconf.texi (AC_LIBOBJ vs LIBOBJS): Mark
4289 `LIBOBJDIR' as experimental.
4291 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): MSYS `ln -s' fails
4292 with a target directory; it's internally implemented as `cp'
4293 anyway, but since Autoconf advertises the possibility to use
4294 a target directory when LN_S is `ln -s', we need to find out.
4295 Reported by Rolf Ebert <rolf.ebert.gcc@gmx.de> against MSYS,
4296 analyzed by Keith Marshall <keith.marshall@total.com>.
4298 * THANKS: Update.
4300 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
4302 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Just output
4303 confdefs.h as-is. In general, if it has backslash-newline or the
4304 like, then it doesn't work either to sort or to remove empty
4305 lines.
4307 2006-04-09 Stepan Kasal <kasal@ucw.cz>
4309 * tests/Makefile.am (AUTOCONF_FILES): Fix typo in the comment.
4311 2006-04-09 Alexandre Duret-Lutz <adl@gnu.org>
4313 * lib/autom4te.in (Automake-preselections): Preselect
4314 _AM_SUBST_NOTMAKE.
4316 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>
4318 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Use '\'' for an
4319 apostrophe within a single-quoted string, as this is the usual
4320 tradition and is easier to read than '"'"'. Don't rely on the
4321 shell treating "$/" like '$/'. Use a more-consistent indenting
4322 style for the trap.
4324 2006-04-09 Eric Blake <ebb9@byu.net>
4326 * tests/autotest.at (Backquote command substitution),
4327 (Multiline backquote command substitution): Remove mistaken
4328 AT_NO_CMDSUBST from the 2006-03-14 patch, which was meant to be
4329 applied...
4330 (Parenthetical command substitution, Multiline parenthetical
4331 command substitution): here.
4333 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>
4335 Import macros from gnulib (often changing their name).
4337 * NEWS: AC_C_TYPE_LONG_DOUBLE is now obsolete.

4349 (Pointers): Add Gnulib URL.
4350 (Particular Functions): Alphabetize. Add AC_FUNC_STRTOLD.
4351 (Generic Functions): Add AC_CHECK_FUNCS_ONCE. Refer to new
4352 Gnulib section.
4353 (Particular Headers): Add AC_HEADER_ASSERT. For stdbool.h,

4355 Gnulib rather than trying to substitute stdbool code.
4356 (Generic Headers): Add AC_CHECK_HEADERS_ONCE.
4357 (Generic Declarations): Add AC_CHECK_DECLS_ONCE.
4358 (Particular Structures): Add AC_STRUCT_DIRENT_D_INO,

4361 headers too.
4362 Add AC_TYPE_INT8_T, AC_TYPE_INT16_T, AC_TYPE_INT32_T, AC_TYPE_INT64_T,
4363 AC_TYPE_INTMAX_T, AC_TYPE_INTPTR_T, AC_TYPE_LONG_DOUBLE,
4364 AC_TYPE_LONG_DOUBLE_WIDER, AC_TYPE_LONG_LONG_INT, AC_TYPE_UINT8_T,
4365 AC_TYPE_UINT16_T, AC_TYPE_UINT32_T, AC_TYPE_UINT64_T,
4366 AC_TYPE_UINTMAX_T, AC_TYPE_UINTPTR_T, AC_TYPE_UNSIGNED_LONG_LONG_INT.
4367 (C Compiler): Move AC_C_LONG_DOUBLE to ...
4368 (Obsolete Macros): here. Under AC_LONG_DOUBLE, mention
4369 AC_TYPE_LONG_DOUBLE or AC_TYPE_LONG_DOUBLE_WIDER instead.
4370 (Posix Variants): Add AC_USE_SYSTEM_EXTENSIONS.
4371 (Coding Style). Don't mention m4_expand_once.
4372 * lib/autoconf/c.m4 (AC_C_LONG_DOUBLE): Implement via
4373 AC_TYPE_LONG_DOUBLE_WIDER. Now obsolete.
4374 * lib/autoconf/functions.m4 (_AH_CHECK_FUNCS): New macro.
4375 (AC_CHECK_FUNCS): Use it.

4380 (AC_HEADER_ASSERT): New macro.
4381 (AC_HEADER_STDBOOL): Don't assume "#error" works.
4382 Catch a bug in IBM AIX xlc compiler version 6.0.0.0.
4383 Catch a bug in an HP-UX C compiler.
4384 * lib/autoconf/specific.m4 (AC_USE_SYSTEM_EXTENSIONS): New macro.
4385 * lib/autoconf/types.m4 (AC_TYPE_INTMAX_T. AC_TYPE_UINTMAX_T):
4386 (AC_TYPE_INTPTR_T, AC_TYPE_UINTPTR_T. AC_TYPE_LONG_DOUBLE):
4387 (AC_TYPE_LONG_DOUBLE_WIDER, AC_C_LONG_DOUBLE, AC_TYPE_LONG_LONG_INT):
4388 (AC_TYPE_UNSIGNED_LONG_LONG_INT, _AC_TYPE_INT, _AC_TYPE_UNSIGNED_INT):
4389 (_AC_STRUCT_DIRENT, AC_STRUCT_DIRENT_D_INO, AC_STRUCT_DIRENT_D_TYPE):
4390 New macros.
4392 * tests/mktests.sh (ac_exclude_list, au_exclude_list): Do not
4393 use /^foo|bar$/, it does not mean /^(foo|bar)$/.
4395 2006-04-08 Stepan Kasal <kasal@ucw.cz>
4397 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Fix the wording
4398 of the warning introduced by the 2001-08-28 change.
4400 2006-04-08 Stepan Kasal <kasal@ucw.cz>,
4401 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4403 * lib/autoconf/general.m4 (AC_CACHE_SAVE): All `ac_cv_env_foo'
4404 variables shall be overriden by the cache.
4405 * tests/torture.at (AC_ARG_VAR): Test also with a first value
4406 that contains braces.
4408 2006-04-07 Stepan Kasal <kasal@ucw.cz>
4410 Revert the patch from 2006-04-01 and only improve
4411 _AS_DETECT_BETTER_SHELL:
4413 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Do not optimize; do not
4414 skip nonexistent directories.
4415 (_AS_DETECT_BETTER_SHELL): The optimization is moved here--try
4416 only shell candidates which exist.
4417 (AS_UNAME): No need to give three parameters to _AS_PATH_WALK.
4418 * lib/autotest/general.m4 (AT_INIT): No need to give three
4419 parameters to _AS_PATH_WALK.
4421 2006-04-07 Stepan Kasal <kasal@ucw.cz>,
4422 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4424 * bin/autoupdate.in (handle_autoconf_patches): Change the way we
4425 distinguish m4sugar macros.
4426 * tests/tools.at (autoupdating with aclocal and m4_include):
4427 New test. Bug reported by Gary V. Vaughan <gary@gnu.org>,
4428 test case by Noah Misch <noah@cs.caltech.edu>.
4430 2006-04-07 Stepan Kasal <kasal@ucw.cz>
4432 Revert my change from 2006-03-17, in other words:
4433 * lib/m4sugar/m4sh.m4 (AS_BOURNE_COMPATIBLE): Insert BIN_SH=xpg4
4434 and DUALCASE=1.
4435 (AS_SHELL_SANITIZE): Remove DUALCASE=1.
4436 * doc/autoconf.texi (Special Shell Variables) <BIN_SH>: Say that
4437 it is set.
4439 2006-04-07 Eric Blake <ebb9@byu.net>
4441 * doc/autoconf.texi (Programming in M4sh): Document that
4442 AS_MKDIR_P exits the script on failure.
4443 * lib/autotest/general.m4: Remove redundant AS_ERROR.
4445 2006-04-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4447 * config/elisp-comp, config/install-sh, config/mdate-sh,
4448 config/missing, config/mkinstalldirs: Sync from Automake.
4450 * lib/Autom4te/FileUtils.pm, lib/Autom4te/Struct.pm: Sync
4451 from Automake.
4453 * doc/make-stds.texi: Sync from gnulib.

4457 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_O): Inside cache
4458 check, s/ac_exeext/ac_cv_exeext/. Fixes regression introduced
4459 2006-04-01.
4461 2006-04-06 Stepan Kasal <kasal@ucw.cz>,
4462 Eric Blake <ebb9@byu.net>,
4463 Paul Eggert <eggert@cs.ucla.edu>,
4464 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4466 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): Fix the detection of
4467 whether `set' quotes correctly: redirect stderr of the tested
4468 `set', and use a subshell, for Ultrix; use `sed' instead of
4469 `grep' for zsh `set' which may write binary output; match only
4470 at the beginning of a line, to avoid false positives.
4471 In order to avoid false positives by unrelated variables with
4472 multiline content, put the dump algorithm in a subshell and
4473 unset all variables containing newlines (except some which are
4474 special to the shell). Warn about cache variables that are
4475 unset.
4477 2006-04-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4479 * config/config.guess, config/config.sub, config/texinfo.tex:
4480 Sync from upstream.
4482 * tests/mktests.sh: Reword comments.
4484 * tests/mktests.sh: Only skip internal macros starting with
4485 `_AC_' or `__AC_'. Noted by Stepan Kasal.
4486 Update exclusion lists for the test suite to this end:
4487 (AC_ARG_VAR): Do test this now.
4488 (AC_SEARCH_LIBS, AC_REPLACE_FUNCS): Need an argument.
4489 (AC_LINKER_OPTION): Remove (renamed to _AC_LINKER_OPTION).
4490 (AC_LIST_MEMBER_OF): Likewise (renamed to _AC_LIST_MEMBER_IF).
4491 (AC_LINK_FILES): Obsoleted since (and thus AU_DEFUN'ed).
4493 * doc/autoconf.texi (Shell Substitutions): Mention the MSYS
4494 shell issue with double-quoted command substitutions of native
4495 commands.
4496 Reported to MSYS by Mark Cave-Ayland, to Autoconf by Keith
4497 Marshall.
4499 * Makefile.maint (sc_cast_of_argument_to_free): Do not fail when
4500 no file matches the glob, discard the warning, set `nullglob'.
4501 (syntax-check): Likewise.
4502 (sc_cast_of_x_alloc_return_value): Likewise.
4503 (sc_cast_of_alloca_return_value, sc_error_exit_success)
4504 (sc_prohibit_jm_in_m4, .re-list, sc_unmarked_diagnostics)
4505 (m4-check): Likewise.
4506 (sc_system_h_headers): Do not print rule on execution.
4507 (sc_tight_scope): Do not fail for non-existing `src' directory.
4508 (sc_changelog): Skip the Copyright footer.
4509 * lib/autoconf/lang.m4: Remove trailing space.
4511 * lib/autoconf/status.m4: More replacements to
4512 <tab><space> where this makes sense.
4514 2006-04-06 Stepan Kasal <kasal@ucw.cz>
4516 * tests/Makefile.am (maintainer-check-posix):
4517 s/POSIXLY_CORRECTLY/POSIXLY_CORRECT/
4519 * lib/autoconf/status.m4 (_AC_CONFIG_FOOS): Append TAGS to
4520 ac_config_<foo>s again, sometimes normalized, sometimes not.
4521 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_LINKS):
4522 (AC_CONFIG_COMMANDS): Do not do so here.
4523 (_AC_CONFIG_REGISTER_DEST): Double quote the tags in macros _AC_LIST_TAGS
4524 and_AC_LIST_TAG_COMMANDS; fixes another regression introduced by the
4525 2005-07-25 rewrite. Noticed by Noah Misch.
4527 * lib/autoconf/general.m4 (AC_PRESERVE_HELP_ORDER): Do not define
4528 _AC_PRESERVE_HELP_ORDER, ...
4529 (AC_ARG_ENABLE, AC_ARG_WITH): ... use AC_PROVIDE_IFELSE insetad.
4531 * lib/autoconf/general.m4 (AC_ARG_VAR): Do not use m4_divert_once
4532 inside m4_expand_once; it is redundant.
4534 * lib/autoconf/general.m4 (_AC_INIT_HELP): Remove the broken support
4535 for --help from Cygnus `configure.'
4537 2006-04-06 Paul Eggert <eggert@cs.ucla.edu>
4539 * doc/autoconf.texi (C Compiler): Warn about #error. Follows up
4540 on a patch proposed by Ralf Wildenhues.
4542 2006-04-05 Paul Eggert <eggert@cs.ucla.edu>
4544 * lib/autoconf/status.m4: Replace <space>''<tab> with
4545 <tab><space> where this makes sense.
4547 2006-04-05 Howard Chu <hyc@highlandsun.com> (trivial change)
4548 Noah Misch <noah@cs.caltech.edu>
4550 * lib/autoconf/general.m4 (AC_PRESERVE_HELP_ORDER): New macro.
4551 (AC_ARG_ENABLE, AC_ARG_WITH): Adjust.
4552 * doc/autoconf.texi (Help Formatting): New node.
4553 * NEWS: Announce AC_PRESERVE_HELP_ORDER.
4555 2006-04-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4557 * TODO, config/Makefile.am, lib/freeze.mk, lib/autoconf/c.m4,
4558 lib/autoconf/specific.m4, lib/autoconf/status.m4,
4559 lib/autoconf/types.m4, lib/autotest/general.m4,
4560 tests/mktests.sh, tests/torture.at: White space cleanup:
4561 remove some SPACE before TAB, or add quoting ('' or @&t@).
4563 * NEWS, TODO, bin/autoreconf.in: `filesystem' -> `file system'.
4565 * doc/autoconf.texi (Shell Substitutions): Document `^' vs. `|'.
4567 2006-04-05 Eric Blake <ebb9@byu.net>
4569 * lib/autotest/general.m4 (AT_INIT): Prep AT_*_all, so that an
4570 empty test suite works.
4571 * tests/autotest.at (Empty test suite): Remove xfail.
4573 2006-04-05 Noah Misch <noah@cs.caltech.edu>
4575 * lib/autoconf/status.m4 (_AC_CONFIG_FOOS): Do not append normalized
4576 TAGS to ac_config_<foo>s.
4577 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_LINKS): Do so here.
4578 (AC_CONFIG_COMMANDS): Append NAME to ac_config_commands without
4579 normalizing it, consistent it with previous releases.

4589 * tests/mktests.sh: Don't use 'cat'; just read the files directly.
4590 Prefer 'sort -u' to 'sort | uniq'. Filter data before sorting it.
4591 Use 'comm' rather than N instances of grep; this also fixes a bug
4592 whereby substrings were incorrectly matched, causing us to not
4593 generate tests for AC_F77_NAME_MANGLING and AC_FUNC_LSTAT.
4594 (exclude_list): Exclude empty macros.
4595 (ac_exclude_list): Exclude AC_INCLUDES_DEFAULT.

4600 Switch from grep to awk syntax.
4601 (ac_exclude_script): Renamed from ac_exclude_egrep.

4678 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't try to
4679 detect exeext, it will be done by _AC_COMPILER_EXEEXT_O; just set
4680 ac_file to the name of the default output file and call
4681 _AC_COMPILER_EXEEXT_WORKS. Move the definition of ac_files and the
4682 initial `rm' of the candidate files...
4683 (_AC_COMPILER_EXEEXT): ... here and simplify them. Moreover, use
4684 the same list in subsequent `rm' calls, and for the temporary
4685 redefinition of ac_clean_files; call _AC_COMPILER_OBJEXT at the end,
4686 and don't call the other _AC_COMPILER_EXEEXT_* macros directly, use...
4687 (_AC_COMPILER_EXEEXT_TESTS): ... this new macro.
4688 (_AC_COMPILER_EXEEXT_O): Don't export ac_cv_exeext, it's not needed (or
4689 no longer needed) by libtool. Make it a cache check.
4690 (_AC_COMPILER_EXEEXT_CROSS): Remove the comment, it was obviously
4691 copied here by mistake.
4692 (AC_NO_EXECUTABLES): Redefine _AC_COMPILER_EXEEXT_TESTS, not
4693 _AC_COMPILER_EXEEXT.
4694 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX, AC_PROG_OBJC): Do not call

4730 subordinate tools.
4731 * lib/Autom4te/General.pm (getopt): Make -v and -d incremental.
4732 * doc/autoconf.texi (autoreconf Invocation): Document it.
4734 * doc/autoconf.texi: Use `Cygwin', `MinGW', and `license' consistently.

4766 2006-04-01 Stepan Kasal <kasal@ucw.cz>
4768 * bin/autoupdate.in: Handle m4 builtins and m4sugar macros together--
4769 switch all of them on and of when necessary. Fixes the bug when
4770 m4sugar macros (e.g., m4_define) were expanded after the first
4771 automatic update (e.g., after AC_PREREQ or AC_INIT).
4773 2006-03-31 Paul Eggert <eggert@cs.ucla.edu>

4804 (File System Conventions): Put discussion of // versus / here, and
4805 modernize it a bit.

4820 * bin/autoscan.in: The value of find_configure_ac should be
4821 checked for existence, so we don't barf over a nonexisting
4822 configure.ac. Reported by Laurence Darby <ldarby@tuffmail.com>.
4824 2006-03-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

4933 IFS even in case of empty `$PATH'.
4935 2006-03-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4937 * lib/autotest/general.m4 (AT_INIT) <at_optarg>: Optimize
4938 `expr' away if there is nothing to do.

4944 * doc/autoconf.texi (testsuite Invocation) < --keywords >:
4945 Update and fix the documentation accordingly.
4946 * tests/autotest.at (Keywords): Renamed to..
4947 (Keywords and ranges): .. this. Extended to make sure negated
4948 keywords, keywords taken from AT_SETUP arguments, and numeric
4949 test ranges work, and that matching is case-insensitive.

4967 nor C89 mode, set `$ac_cv_prog_cc_stdc' to `no' instead of
4968 trying to execute the command `no'.
4970 * lib/autoconf/lang.m4 (AC_LANG_CONFTEST): AC_DEFUN this, not
4971 m4_define, so that the requirements of `AC_INCLUDES_DEFAULT' are
4972 expanded outside.
4974 * doc/autoconf.texi (autoconf Invocation): Fix typos in trace
4975 example. Do not emphasize `$%', it is hardly new and special.
4976 Reported by Edouard Bechetoille <ebecheto@ens-lyon.fr>.
4978 * doc/autoconf.texi (Limitations of Usual Tools): Document
4979 OpenBSD and traditional `grep' failure to handle multiple

5006 the obsolescent AC_HEADER_STDC.
5007 (AC_FOO_IFELSE vs AC_TRY_FOO): Don't use #error; test programs
5008 can't rely on it.
5010 2006-03-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

5017 * tests/c.at (AC_PROG_CPP without warnings, AC_PROG_CPP via CC):
5018 Require that /lib/cpp include stdio.h correctly. Solaris 10's
5019 doesn't. Problem reported by D'Arcy A MacIsaac and diagnosed by
5020 Ralf Wildenhues.
5022 2006-03-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5024 * lib/autoconf/status.m4 (_AC_SED_CMD_LIMIT): The limit for
5025 HP-UX sed is 99 commands, not 100.
5026 (_AC_OUTPUT_FILES_PREPARE): Do not count the `}' of an
5027 _AC_SUBST_FILES fragment. Separate `{' and `r' commands by
5028 newline for portability.
5029 * tests/torture.at (Torturing config.status): Also test 100
5030 AC_SUBST_FILE invocations. Fix test to actually verify the

5500 * tests/semantics.at (AC_C_BIGENDIAN): Pass --force to autoheader,
5501 in case the computer is too quick. Double quote the configure.ac
5502 snippets.
5504 * tests/local.at (AT_CHECK_AUTOCONF): Always pass --force to prevent
5505 problems if the testsuite were running too fast.
5507 2005-09-18 Paul Eggert <eggert@cs.ucla.edu>
5509 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Look for X11/Xlib.h
5510 and XrmInitialize rather than X11/Intrinsic.h and XtMalloc
5511 (which belong to Xt, not X itself). See Debian bug 327655.
5512 * NEWS: Mention this.
5514 2005-09-07 Stepan Kasal <kasal@ucw.cz>
5516 * lib/autoconf/c.m4 (AC_LANG_SOURCE(C)): Remove an incorrect comment.
5518 2005-09-06 Paul Eggert <eggert@cs.ucla.edu>
5520 * config/move-if-change: Don't output "$2 is unchanged";
5521 suggested by Ben Elliston. Handle weird characters correctly.
5523 2005-09-06 Stepan Kasal <kasal@ucw.cz>
5525 * lib/autoconf/libs.m4 (AC_SEARCH_LIBS): Merge the two AC_LINK_IFELSE
5526 calls, so that the final expansion of this macro is shorter.
5527 Create the conftest.$ac_ext outside the `for' loop, to speed the run.
5528 Do not use `break' in the argument to AC_LINK_IFELSE, it would skip
5529 the cleanup there. Use AS_VAR_* macros, to be more general.
5530 * tests/semantics.at (AC_SEARCH_LIBS): Check for the cleanup.
5532 * lib/autoconf/general.m4: Use AS_IF where appropriate.
5534 * lib/m4sugar/m4sh.m4 (AS_IF): Use m4_default.
5536 2005-09-01 Stepan Kasal <kasal@ucw.cz>
5538 * doc/autoconf.texi (Configuration Headers): Add an index entry
5539 for AH_HEADER.
5541 2005-08-26 Pavel Roskin <proski@gnu.org>
5543 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): Use shell variable
5544 XMKMF to locate xmkmf. Make XMKMF precious. Export CC when
5545 running xmkmf.
5547 2005-08-26 Paul Eggert <eggert@cs.ucla.edu>
5549 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE):
5550 The previous patch didn't work, so try a better one.
5552 2005-08-26 Stepan Kasal <kasal@ucw.cz>
5554 * doc/autoconf.texi (Programming in M4sh) <AS_TR_CPP>: Fix m4 quoting
5555 in the example. Reported by Bruno Haible.
5556 <AS_TR_SH>: Likewise. Also modify the example to be more convincing:
5557 "if $undefined_var;" succeeds with my shell.
5559 * lib/autoconf/general.m4 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST,
5560 AC_CANONICAL_TARGET): Define by AC_DEFUN, no need to use AC_DEFUN_ONCE;
5561 but change the m4_divert_text to m4_divert_once.
5563 2005-08-25 Paul Eggert <eggert@cs.ucla.edu>
5565 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE):
5566 Work around bug in Solaris /usr/xpg4/bin/awk.
5567 The bug is present in at least Solaris 8 through 10.
5569 2005-08-24 Stepan Kasal <kasal@ucw.cz>
5571 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Simplify; rejecting
5572 some evil values and relying on the fact that $* concatenates the
5573 parameters by the first character from IFS.
5575 2005-08-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
5576 Stepan Kasal <kasal@ucw.cz>
5578 * lib/autoconf/status.m4 (_AC_CONFIG_REGISTER_DEST): When the
5579 first header appears, define AH_HEADER.
5580 * doc/autoconf.texi (Configuration Headers): Document AH_HEADER.
5581 Update limitations about when to call AC_CONFIG_HEADERS.
5582 (Configuration Commands): Document that AC_CONFIG_COMMANDS_PRE
5583 parameter can call AC_SUBST, AC_DEFINE, or AC_CONFIG_FOOS; explain
5584 that AC_CONFIG_COMMANDS_PRE and AC_CONFIG_COMMANDS_POST are not
5585 ``Configuration Actions''; fix their index entries.
5587 * lib/autotest/general.m4 (AT_INIT): Process multiple keywords
5588 options correctly. Process N-M as M-N if M is smaller than N.
5589 Process ranges correctly so that N-N will run only N.
5590 Sort and uniquify the tests that will be run. If there is more
5591 than one test, reinsert the banners for the tests.
5592 * tests/autotest.at (Keywords): Unmark XFAIL.
5594 2005-08-23 Stepan Kasal <kasal@ucw.cz>
5596 * lib/autoconf/general.m4 (_AC_DEFINE_Q): Strip the parameter list
5597 before passing the macro name to AH_TEMPLATE.
5599 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): config.status
5600 now opens log after option processing; in particular, --version
5601 and --help do not touch config.log.
5603 * Makefile.maint: Revert the change from 2005-08-12.
5605 2005-08-22 Stepan Kasal <kasal@ucw.cz>

5614 (Autotest Logs, Writing testsuite.at, testsuite Invocation):
5615 Language cleanup.
5617 * doc/autoconf.texi (Defining Symbols, Changed Results):
5618 Prepend to LIBS, not append, in examples.
5620 2005-08-16 Stepan Kasal <kasal@ucw.cz>
5622 When building in place, set srcdir="."; suggested by Tim Van Holder.
5624 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Do this; to recognize
5625 build in place, we need ac_pwd, and thus have to AC_REQUIRE ...
5626 (_AC_INIT_DIRCHECK): ... this macro and AC_DEFUN both of them.
5627 * lib/autoconf/status.m4 (_AC_SRCDIRS): Fix a comment: srcdir="."
5628 does not mean "no --srcdir option".
5630 2005-08-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5632 * tests/autoscan.at (autoscan): New file.
5633 * tests/suite.at: Use it.

5635 Reported against Libtool by Gideon Go <gideon.go@gmail.com>.
5637 * tests/autotest.at (Keywords): Test keywords combinations.
5639 2005-08-12 Stepan Kasal <kasal@ucw.cz>
5641 * Makefile.maint (GZIP_ENV): When checking the help text of gzip,
5642 add "2>&1"; gzip 1.2.4 prints help on stderr.
5644 2005-07-27 Stepan Kasal <kasal@ucw.cz>
5646 * lib/autotest/general.m4 (_AT_DECIDE_TRACEABLE): The symbol at_reason
5647 was pushdef'ed twice while popped only once. Push it only once.
5648 (_AT_CHECK): Cosmetic changes to the "case $at_status" command.
5650 2005-07-26 Stepan Kasal <kasal@ucw.cz>
5652 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): The message is now

5659 * lib/m4sugar/m4sugar.m4 (m4_strip): Comment fix---change tab to
5660 "<tab>" in comment, so that the point is understandable.
5662 2005-07-25 Stepan Kasal <kasal@ucw.cz>
5664 Rewrite substantial part of lib/autoconf/status.m4.
5665 The main change is that CONFIG_FILES, CONFIG_HEADERS, CONFIG_LINKS,
5666 and CONFIG_COMMANDS are not processed in four separate loops.
5667 Instead, there is one main loop. This alows that the common code
5668 is expanded only once, thus config.status (and configure) is smaller.
5670 The registration mechnism in AC_CONFIG_FILES and cousins also changed;
5671 the AC_LIST_FILES and cousins macros are no longer used.
5673 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES, _AC_OUTPUT_HEADERS,
5674 _AC_OUTPUT_LINKS, _AC_OUTPUT_COMMANDS): Renamed to ...
5675 (_AC_OUTPUT_FILE, _AC_OUTPUT_HEADER, _AC_OUTPUT_LINK,
5676 _AC_OUTPUT_COMMAND): ..., respectively. These macros no longer
5677 contain the initialization, nor the for loop, nor the associated
5678 commands; all these go to ...
5679 (_AC_OUTPUT_MAIN_LOOP): ... this new macro, called from
5680 _AC_OUTPUT_CONFIG_STATUS.
5681 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST, _AC_CONFIG_SPLIT_FILE_IN):
5682 Nuked; the code was merged into _AC_OUTPUT_MAIN_LOOP.
5683 (_AC_OUTPUT_FILE): The creation of the sed script ...
5684 (AC_OUTPUT): ... and the setup of ac_vpsub goes to ...
5685 (_AC_OUTPUT_FILES_PREPARE): ... a new macro, also called from
5686 _AC_OUTPUT_MAIN_LOOP.
5687 (_AC_CONFIG_FILES, _AC_CONFIG_HEADERS, _AC_CONFIG_LINKS,
5688 _AC_CONFIG_COMMANDS): Use ...
5689 (_AC_CONFIG_FOOS): ... this new macro, which uses these ...
5690 (_AC_CONFIG_REGISTER, _AC_CONFIG_REGISTER_DEST): ... new macros.
5691 (_AC_CONFIG_FILE, _AC_CONFIG_HEADER, _AC_CONFIG_LINK,
5692 _AC_CONFIG_COMMAND, _AC_CONFIG_DEPENDENCIES): No longer needed.
5693 (_AC_CONFIG_DEPENDENCY): Update, it uses these ...
5694 (_AC_CONFIG_DEPENDENCY_DEFAULT, _AC_FILE_DEPENDENCY_TRACE_COLON):
5695 ... new macros.
5696 (_AC_CONFIG_UNIQUE): Update.
5697 (AC_LIST_FILES, AC_LIST_HEADERS, AC_LIST_LINKS, AC_LIST_COMMANDS):
5698 Replaced by this ...
5699 (_AC_LIST_TAGS): ... new common macro.
5700 (AC_LIST_FILE_COMMANDS, AC_LIST_HEADER_COMMANDS, AC_LIST_LINK_COMMANDS,
5701 AC_LIST_COMMAND_COMMANDS): Replaced by this ...
5702 (_AC_LIST_TAG_COMMANDS): ... new common macro.
5703 (_AC_CONFIG_COMMANDS_INIT): Moved top to the `registration' section;
5704 this didn't belong to the `config commands' section.
5705 (_AC_OUTPUT_COMMANDS_INIT): Don't initialize, m4_ifdef is our friend.
5706 (AC_CONFIG_COMMANDS_PRE, AC_OUTPUT_COMMANDS_PRE,
5707 AC_CONFIG_COMMANDS_POST): Moved to a new section, these didn't belong
5708 to the `config commands' section either.
5709 (AC_CONFIG_SUBDIRS): Don't touch diversion DEFAULTS.
5710 (_AC_LIST_SUBDIRS): Don't initialize, m4_ifdef is our friend.
5712 ... and many changes to the comments nearby.
5714 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): At the end of the day,
5715 set ac_subdirs_all='_AC_LIST_SUBDIRS'.
5716 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
5717 AC_CONFIG_COMMANDS(command:input,...) is no longer allowed.
5718 (#define header templates): The comment at the top of the generated
5719 header now includes the name(s) of the source file(s).
5721 Several unrelated small changes:
5723 * lib/autoconf/general.m4 (AC_CACHE_VAL): Be didactic, quote the first
5724 parameter to AC_DIAGNOSE.
5725 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS): Likewise.
5726 (_AC_LINK_FILES_CNT): Don't AU_DEFUN this; it causes confusing messages
5727 with autoupdate; use m4_define_default inside AU_DEFUNed AC_LINK_FILES.
5728 (AC_OUTPUT): In the compatibility code, use m4_ifvaln, to be consistent
5729 with AU::AC_OUTPUT.
5730 (AU::AC_OUTPUT): Don't double-quote $2 and $3, the compatibility code
5731 in AC_OUTPUT doesn't double-quote it either.
5732 * tests/tools.at (autoupdate): AU::AC_OUTPUT no longer double-quotes the
5733 parameters.
5735 2005-07-10 Stepan Kasal <kasal@ucw.cz>
5737 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Document which
5738 versions of Portland Group compiler produce single- and double-quoted
5739 -cmdline argument. Reported by Steven G. Johnson <stevenj@fftw.org>
5740 and Ole Holm Nielsen <Ole.H.Nielsen@fysik.dtu.dk>.
5742 2005-07-07 Paul Eggert <eggert@cs.ucla.edu>
5744 * tests/local.at (AT_CONFIG_CMP): Ignore lines like "LIBS=''" too.
5745 This is a corrected version of yesterday's patch.
5747 2005-07-07 Stepan Kasal <kasal@ucw.cz>
5749 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Report the full
5750 path, too; insert a "===" to emphasize the line.
5752 * lib/autoconf/general.m4 (AC_CANONICAL_BUILD): Rename
5753 ac_cv_build_alias to ac_build_alias.
5754 (AC_CANONICAL_HOST, AC_CANONICAL_TARGET): Simplify.
5756 On 2005-02-24, an unintentional AC_SUBST([CC]) was introduced; this
5757 change eliminates it. Problem reported by Alexandre Duret-Lutz.
5758 * lib/autoconf/general.m4 (_AC_ARG_VAR_PRECIOUS): Move the AC_SUBST ...
5759 (AC_ARG_VAR): ... here.
5760 (_AC_INIT_PREPARE): Call AC_SUBST for build_alias, host_alias and
5761 target_alias.
5763 Keep a list of all precious variables and process them with one simple
5764 for loop, instead of expanding all commands, or, OTOH, complicated
5765 processing of output of "set".
5766 * lib/autoconf/general.m4 (_AC_ARG_VAR_PRECIOUS): Acumulate the
5767 variable names in new macro...
5768 (_AC_PRECIOUS_VARS): ... which will be assigned to ac_precious_vars.
5769 (_AC_ARG_VAR_STORE): New macro which writes to diversion PARSE_ARGS
5770 a loop to assign all ac_env_* and ac_cv_env_* variables.
5771 (_AC_ARG_VAR_VALIDATE): Use shell variable ac_precious_vars, divert
5772 to INIT_PREPARE.
5773 (_AC_INIT_DEFAULTS): At the end, if _AC_PRECIOUS_VARS is set, assign
5774 its value to shell variable ac_precious_vars and call
5775 _AC_ARG_VAR_STORE and _AC_ARG_VAR_VALIDATE.
5776 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Don't call
5777 _AC_ARG_VAR_VALIDATE.
5779 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Move AC_LANG_PUSH(C)
5780 and the AC_SUBSTs ...
5781 (AC_INIT): ... here.
5783 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Changed the title of
5784 the ac_subst_files section in config.log.
5786 * tests/local.at (AT_CONFIG_CMP): Revert Paul's previous change.
5788 2005-07-06 Paul Eggert <eggert@cs.ucla.edu>
5790 * NEWS: New macro AC_C_TYPEOF.
5791 * doc/autoconf.texi (C Compiler): Document AC_C_TYPEOF.

5793 * tests/c.at (C keywords): Test AC_C_TYPEOF.
5795 Fix problems reported by Nicolas Joly.
5796 * tests/base.at (Input/Output): Ignore 'loading site script' chatter.
5797 * tests/local.at (AT_CONFIG_CMP): Ignore lines like "LIBS=''" too.
5798 They are generated by the Tru64 v5.1B shell.
5800 2005-07-05 Stepan Kasal <kasal@ucw.cz>
5802 Fix my changes from 2005-07-01; reported by Noah Misch.
5803 * lib/autoconf/status.m4 (_AC_CONFIG_DEPENDENCIES): Fix the
5804 description, the macro now accepts only a single tag.
5805 (_AC_CONFIG_UNIQUE): Likewise; s/AC_File/[$1]/
5807 Fix cases when the varsions of Autoconf and Autotest don't match.
5808 Reported by Noah Misch.
5809 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Set also
5810 at_top_builddir, for compatibility with older autotest.
5811 * lib/autotest/general.m4 (AT_INIT): If at_top_build_prefix
5812 is not set, use at_top_builddir, for compatibility with older
5813 versions of autoconf.
5815 2005-07-04 Paul Eggert <eggert@cs.ucla.edu>
5817 * bin/autom4te.in ($m4): Catch usages like --nesting-limit=2048.
5818 Problem reported by Patrick Welche.
5820 2005-07-03 Paul Eggert <eggert@cs.ucla.edu>
5822 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Use &, not |, in
5823 sed substitution command, so that we allow | in program prefixes
5824 and program suffixes. (& is a problem anyway; we're not fixing
5825 that here.)
5826 * lib/autoconf/status.m4 (AC_CONFIG_FILES): Likewise, for
5827 configure_input, top_builddir, srcdir, etc.
5828 * lib/autotest/general.m4 (AT_INIT): Likewise, for
5829 PATH_SEPARATOR in AUTOTEST_PATH.
5831 2005-07-02 Alexandre Duret-Lutz <adl@gnu.org>
5833 * lib/autoconf/general.m4 (AC_SITE_LOAD): Rewrite the
5834 for loop over config.site files using `set', to allow
5835 directory names containing IFS characters.
5837 2005-07-01 Paul Eggert <eggert@cs.ucla.edu>
5839 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Remove the tests for
5840 directories with weird names. Apparently some people like living
5841 on the edge. However, improve the test that "pwd" actually does
5842 report a name for the working directory.
5843 * NEWS: Remove the claim that we test for funny chars in dir names.
5845 2005-07-01 Stepan Kasal <kasal@ucw.cz>
5847 * lib/autoconf/general.m4 (AC_FOREACH): Make obsolete; it's

5857 about #include <config.h>.
5858 (Generic Functions): Mention the Gnulib project.
5859 (Limitations of Usual Tools) <sed>: Another minor rephrasing.
5861 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Use a here
5862 document to output the default config_* lists to config.status.
5863 Don't recognize option --file, if the functionality is not there.
5864 Likewise for --header; moreover, recognize --he and --h as shortcuts
5865 for --help in that case.
5867 * lib/autoconf/status.m4: Fix the order of the "sections", so that it
5868 matches the order of execution. No code changed.
5870 2005-06-30 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5872 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Fix also for
5873 single-quoted -cmdline argument in Portland Group compiler.

5887 * lib/autoconf/general.m4 (AC_ARG_VAR): Move next to _AC_ARG_PRECIOUS.
5889 * lib/autoconf/general.m4 (AC_SUBST_TRACE): New macro, to be traced
5890 instead of AC_SUBST; proposed by Alexandre Duret-Lutz.
5891 (AC_SUBST): Call it.
5892 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Call AC_SUBST_TRACE for
5893 the directory specific variables; but don't call it for configure_input.
5895 2005-06-28 Derek Price <derek@ximbiot.com>
5897 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: Reword recent
5898 addition.
5900 2005-06-23 Paul Eggert <eggert@cs.ucla.edu>
5902 * NEWS: Don't worry about spaces in bindir etc. Only srcdir and working
5903 directory have inherent problems with special characters like spaces,
5904 due to limitations in Make syntax. Problem reported by Alexandre
5905 Duret-Lutz.
5906 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Implement the above.
5907 Also, fix Tru64 porting problem with shell patterns,

5916 * tests/local.at (AT_CHECK_ENV): Simplify regexp slightly.
5918 Fix some more shell quoting problems. Prompted by a bug report
5919 from Justace Clutter.
5920 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Put name of invalid
5921 variable into diagnostic. Make the diagnostic an error, not a warning,
5922 because we really don't support spaces and suchlike in dir names.
5923 (_AC_INIT_SRCDIR): Allow special characters in $ac_unique_file.
5924 Don't worry about backslashes in srcdir; it can't happen now.
5925 (_AC_INIT_PARSE_ARGS): Allow weird characters in ac_optarg.
5926 Simplify ac_optarg handling.
5927 (_AC_ARG_VAR_VALIDATE): Remove unnecessary and inconsistent quotes.

5935 (AT_CONFIG_CMP): Use sed instead of grep plumbing.
5937 * doc/autoconf.texi (Limitations of Usual Tools) <grep>: Mention
5938 that '\|' is not allowed in BREs; recommend using newline separated
5939 list of patterns instead of multiple -e options.
5941 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Remove an old comment.
5943 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Use AC_SUBST/2.
5945 2005-06-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5947 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Fix typo.
5949 2005-06-21 Stepan Kasal <kasal@ucw.cz>
5951 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: Document that
5952 b, t, r, w commands require single space, while : cannot have any.
5953 (Special Shell Variables): Fix sed code this in the example.

5955 * lib/autotest/general.m4 (AT_ARG_OPTION): Fix typo in the description.
5957 * lib/m4sugar/m4sugar.m4 (m4_split): If the parameter is empty,
5958 expand to the empty list. Don't use two pairs of m4_changequote,
5959 it's not necessary.

5968 * doc/autoconf.texi:
5969 Don't mention Solaris versions so much, if a
5970 problem is common to all extant versions of Solaris. Say "SunOS
5971 4" instead of "SunOS" for SunOS 4.
5972 (awk): Mention more of the limitations of traditional Awk.

6000 * man/Makefile.am (MOSTLYCLEANFILES): Add $(srcdir)/*.t.
6001 (.x.1): Ignore the time stamp in the .TH line when deciding whether

6015 * lib/autotest/general.m4 (AT_INIT): Don't accept Solaris 9's diff
6016 -u, since it outputs chatter if the input files are the same.
6017 Problem reported by Ralf Menzel.
6019 2005-06-08 Derek Price <derek@ximbiot.com>
6021 * lib/m4sugar/m4sugar.m4: Undefine include & sinclude rather than
6022 renaming them since they are about to be redefined anyhow.
6024 2005-06-08 Derek Price <derek@ximbiot.com>
6026 * doc/autoconf.texi (Redefined M4 Macros): Add index entries for most
6027 redefined M4 macros to this node. Document m4_include & m4_sinclude.
6028 Move m4_undefine to alphabetical order.
6030 2005-06-07 Paul Eggert <eggert@cs.ucla.edu>
6032 * README: Recommend GNU M4 1.4.3 or later.
6033 * doc/autoconf.texi (Introduction): Likewise.
6034 Reword to avoid some formatting glitches.

6036 Clarify explanation of HP compiler bug.
6037 Redo example output tp match current CVS snapshot.
6038 Use @example.org in email addresses when the examples
6039 might get inadvertently cut-and-pasted into user code.

6042 shown with Autoconf 2.13).
6043 Update ksh info for Solaris 9 and later.
6044 KB -> kB.
6045 Modernize description of Automake versions a bit.

6052 follows its own advice about quoting better.
6053 Reword to avoid some formatting glitches.
6054 * doc/installt.exi: Reword to avoid some formatting glitches.
6056 * doc/autoconf.texi (Limitations of Builtins) <case>: Mention
6057 Tru64 ksh pattern matching bug. Reported against Libtool by
6058 Albert Chin <libtool@mlists.thewrittenword.com> and
6059 Nicolas Joly <njoly@pasteur.fr>.
6061 2005-06-06 Stepan Kasal <kasal@ucw.cz>
6063 m4_cdr of one-member list was [[]] (one-member list containing an
6064 empty string) instead of [] (an empty list. Callers were skewed to
6065 match this misbehaviour. As a consequence of this:
6066 - m4_foreach([x], [], [foo]) expanded to `foo', while
6067 - the expansion of m4_foreach([x], [[]], [foo]) was empty.
6068 This bug has been fixed:
6070 * lib/m4sugar/m4sugar.m4 (m4_cdr): If only one argument is given,
6071 expand to an empty string; print error msg if called without
6072 an argument list.
6073 (m4_foreach, m4_map, m4_map_sep): Don't expect the previous
6074 misbehaviour; handle [] and [[]] correctly.
6076 2005-06-06 Stepan Kasal <kasal@ucw.cz>
6078 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Nuke ac_max_here_lines.

6082 2005-06-06 Ralf Menzel <menzel@ls6.cs.uni-dortmund.de> (trivial change)
6084 * doc/autoconf.texi (Limitations of Usual Tools): Solaris' awk cannot
6085 swallow records with more than 99 fields.
6086 * lib/autotest/general.m4 (AT_INIT): Use the awk builtin `split' to
6087 parse the long line.
6089 2005-06-04 Stepan Kasal <kasal@ucw.cz>
6091 * doc/autoconf.texi (Limitations of Usual Tools): AIX awk cannot
6092 swallow literals longer than 399. Reported by Ralf Wildenhues.
6093 * lib/autotest/general.m4 (AT_INIT): Pass $at_groups though stdin,

6098 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Find g95 in addition
6099 to gfortran, and make these the first two compiler names
6100 checked (following the general autoconf preference for gcc).
6102 2005-06-03 Stepan Kasal <kasal@ucw.cz>
6104 * tests/Makefile.am (check_SCRIPTS): Set to $(wrappers).
6105 (DISTCLEANFILES): Remove $(check_SCRIPTS).
6106 (testsuite): Make sure autotest.m4f is up-to-date before using it.

6110 * lib/autotest/general.m4 (AT_INIT): Don't create a regular
6111 expression of unbounded size when processing the --list
6112 option. This runs afoul of a limit of 399 bytes per regular
6113 expression on AIX. Problem reported by Ralf Wildenhues.
6115 2005-06-01 Paul Eggert <eggert@cs.ucla.edu>

6118 * doc/autoconf.texi (Particular Headers): Reword example
6119 for multiline stdbool replacement.

6121 give all the details about |#_!!_#|.
6122 Reword description of line replacement.
6124 2005-05-31 Dan Manthey <dan_manthey@partech.com>
6126 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Output variables may
6127 now contain newlines, and substituted files must be referenced on
6128 a line alone; the sed scripts to substitute them are now very
6129 different.
6130 (_AC_SED_CMD_LIMIT): Added; single place to store limit on how many
6131 commands can be put in a sed script portably.
6132 * doc/autoconf.texi (Setting Output Variables): Document above
6133 changes. (Particular Header Checks) <AC_HEADER_STDBOOL>: Give exaple

6145 classes in shell scripts. The test was too brittle.
6147 2005-05-25 Stepan Kasal <kasal@ucw.cz>
6149 * bin/autoconf.as: Don't use "shift 2"; it's not portable enough.
6150 * doc/autoconf.texi (Limitations of Builtins): Document this
6151 limitation.
6153 2005-05-24 Stepan Kasal <kasal@ucw.cz>

6163 messages when ac_unique_file is not found.
6164 (AC_CONFIG_MACRO_DIR): Simplify the `if' at the end.
6165 (AC_MSG_CHECKING, AC_MSG_RESULT): Put braces around the two echo
6166 commands, for consistency with AC_MSG_ERROR and such.
6168 * bin/autoconf.as: Make more use of "shift 2" in option processing.

6180 * NEWS: @top_builddir@ is now a dirname, ac_top_builddir will follow.
6181 * lib/autoconf/status.m4 (_AC_SRCDIRS): Rename ...
6182 (ac_top_builddir): ... this ...
6183 (ac_top_build_prefix): ... to this; the old name is also kept, for
6184 backward compatibility.
6185 (ac_top_builddir_sub): New variable, without the trailing slash,
6186 always nonempty.
6187 (_AC_OUTPUT_FILES): s/@top_builddir@/$ac_top_builddir_sub/
6188 * doc/autoconf.texi (Configuration Actions): Rename

6199 2005-05-17 Stepan Kasal <kasal@ucw.cz>
6201 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Don't m4_quote the second
6202 argument to m4_foreach. I guess it was necessary in the past,
6203 but I think it's a no-op now.
6205 2005-05-17 Stepan Kasal <kasal@ucw.cz>
6207 * lib/autoconf/general.m4 (_AC_INIT_HELP): Merge two consecutive
6208 ``cat <<_ACEOF'' commands to one.
6209 (_AC_CANONICAL_SPLIT): Use expr, not ``echo|sed.''
6210 * lib/autoconf/status.m4: On various places, use expr instead of
6211 ``echo|sed.''

6215 a range.
6216 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Use awk to search for

6402 whole-archive (-zallextract, -zdefaultextract) options in the hope of
6403 unique libraries, for the Sun Fortran 95 8.0 compiler. Bug reported
6404 against Libtool by Yury Puhalsky <pooh@cryptopro.ru>.
6406 2005-03-22 Paul Eggert <eggert@cs.ucla.edu>
6408 * NEWS: The configure command now warns you if you attempt to use
6409 a directory whose name contains a special character like space,
6410 newline, or "\".
6411 * doc/autoconf.texi (Installation Directory Variables): Allow
6412 "," in file names. Do not use \@; it's not a portable regexp.
6413 * bin/Makefile.am (edit): Likewise.
6414 * lib/Makefile.am (edit): Likewise.
6415 * tests/Makefile.am (edit): Likewise.
6416 * tests/semantics.at: Likewise.

6419 * lib/autoconf/status.m4 (_AC_SRCDIRS): Likewise.
6420 * doc/autoconf.texi (File System Conventions): Warn about
6421 unportable file names.
6422 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): New macro.
6423 (AC_INIT): Use it.
6424 (_AC_INIT_SRCDIR): Use ac_pwd rather than invoking pwd.
6425 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Propagate
6426 ac_pwd, and quote srcdir.
6427 * lib/autotest/general.m4 (AT_INIT): Quote file name args.
6429 * doc/autoconf.texi: Fix some systematic formatting problems.
6430 ".)" needs a following @: if not at the end of a sentence, and
6431 similarly for "!)". "etc." should be preceded by a comma.
6432 "n-th" -> "@var{n}th". pdksh is still buggy, so update its date.
6434 2005-03-22 Bruno Haible <bruno@clisp.org>
6436 * doc/autoconf.texi (Input): Mention that AC_CONFIG_AUX_DIR's
6437 argument is often called 'build-aux'.
6439 2005-03-07 Stepan Kasal <kasal@ucw.cz>
6441 * doc/autoconf.texi (Quotation Rule Of Thumb): Mention that the
6442 macro AC_TRY_LINK is obsolete.
6443 (Installation Directory Variables): Change `AC_OUTPUT_FILES' to
6444 `AC_CONFIG_FILES'.
6446 2005-02-24 Stepan Kasal <kasal@ucw.cz>
6448 * lib/autoconf/c.m4 (AC_PROG_CC): Be more careful to skip
6449 `/usr/ucb/cc'; use `cl.exe' to distinguish the MS compiler
6450 from a Common Lisp's `cl'.
6451 (AC_PROG_CXX): Behave according to the documentation: don't
6452 search for $ac_tool_prefix$CCC and $CCC, just set CXX=$CCC;
6453 make the variable CCC precious; use `cl.exe', not `cl'.
6455 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
6456 Alexandre Duret-Lutz <adl@gnu.org>
6458 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin from
6459 /dev/null, as "configure" shouldn't read stdin, and this insulates
6460 us from problems (e.g., when testing for "cl"). Also, do this
6461 redirection before invoking "hostname" or "uname", and keep the
6462 original input stream available via...
6463 (AS_ORIGINAL_STDIN_FD): ... this new macro.
6464 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't
6465 bother with "</dev/null" since it's now done at the top of
6466 'configure'.
6467 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Likewise.
6468 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
6469 * lib/autoconf/programs.m4 (_AC_PATH_PROG_FLAVOR_GNU): Likewise.

6474 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
6476 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N_PREPARE): Don't set ECHO_C to
6477 newline if neither \c nor -n work, as that would output two
6478 newlines. Prefer -n to \c. Reported by Stepan Kasal.
6480 2005-02-12 Stepan Kasal <kasal@ucw.cz>
6482 * lib/m4sugar/m4sh.m4 (AS_IF): Define by m4_defun, not m4_define.
6483 This causes that any required macros inside will get before the if.
6484 * doc/autoconf.texi (autom4te.cache): A typo.
6486 2005-02-12 Paul Eggert <eggert@cs.ucla.edu>
6488 Undo previous change, except keep the change to
6489 lib/autoconf/programs.m4 that replaced grep with shell
6490 pattern-matching. This is because net-snmp configure reads stdin.
6491 Reported by Noah Misch.
6493 2005-02-11 Paul Eggert <eggert@cs.ucla.edu>
6495 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin
6496 from /dev/null, as "configure" shouldn't read stdin, and this
6497 insulates us from problems (e.g., when testing for "cl").
6498 Suggested by Alexandre Duret-Lutz. Also, do this redirection
6499 before invoking "hostname" or "uname".
6500 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
6501 _AC_LINK_IFELSE): Undo previous change, as it's no longer needed.
6502 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Don't bother with
6503 "</dev/null" since it's now done at the top of 'configure'.
6504 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
6505 * lib/autoconf/programs.m4 (_AC_PATH_PROG_FLAVOR_GNU): Likewise.
6506 Also, replace grep with shell pattern-matching, to save a process.
6508 2005-02-10 Paul Eggert <eggert@cs.ucla.edu>
6510 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
6511 _AC_LINK_IFELSE): Redirect stdin to /dev/null, in an attempt to
6512 avoid thinking that Allegro Common Lisp's "cl" command is a C++
6513 compiler.
6515 2005-02-09 Paul Eggert <eggert@cs.ucla.edu>
6517 * doc/autoconf.texi (Limitations of Usual Tools): Document that
6518 grep -q isn't portable. Improve grep -s explanation.
6519 Problem reported by Dan Manthey.
6521 2005-02-08 Paul Eggert <eggert@cs.ucla.edu>
6523 * doc/autoconf.texi (Special Shell Variables): Clarify
6524 PATH_SEPARATOR wording; fix typo in IFS. Reported by Gary V. Vaughan.
6526 2005-02-07 Paul Eggert <eggert@cs.ucla.edu>
6528 * doc/autoconf.texi: Use @acronym for DJGPP.
6529 Fix some @code's that should have been @env's, and vice versa.
6530 Sort environment variable names.
6531 Mention that shells no longer inherit IFS.
6532 Don't recommend PATH_SEPARATOR=';' so strongly.
6533 Mention that $RANDOM might expand to the empty string.
6534 "symlink" and "soft link" -> "symbolic link".
6535 Improve mktemp description (reported by Bruno Haible).
6537 2005-02-05 Paul Eggert <eggert@cs.ucla.edu>
6539 * tests/foreign.at (Libtool): Don't overquote AT_SETUP arg.
6540 * tests/m4sh.at (AS_DIRNAME, AS_BASENAME, AS_MKDIR_P, AS_HELP_STRING):
6541 Likewise.
6542 * tests/semantics.at (AC_C_BIGENDIAN, AC_PATH_PROG & AC_PATH_PROGS):
6543 Likewise.
6545 2005-02-04 Paul Eggert <eggert@cs.ucla.edu>
6547 * NEWS: Mention AT_COPYRIGHT.
6549 * tests/local.at (AT_CMP): Use diff directly on input files rather
6550 than copying them.
6552 * lib/autoconf/programs.m4 (AC_PROG_SED): Don't look in
6553 /usr/xpg4/bin since that sed dumps core (at least on Solaris 8).
6555 2005-02-04 Noah Misch <noah@cs.caltech.edu>
6556 and Paul Eggert <eggert@cs.ucla.edu>
6558 * tests/autotest.at (Empty test suite): New test.

6563 2005-02-04 Noah Misch <noah@cs.caltech.edu>
6565 * lib/m4sugar/m4sugar.m4 (m4_re_string, m4_re_word): Revert 2002-03-04.
6566 * tests/local.at (AT_CHECK_M4SUGAR): Add `m4sugar' to keywords.
6567 (AT_CHECK_ENV): Ignore LTLIBOBJS, FC variables, EGREP, FGREP, and SED.
6568 * tests/m4sugar.at (AT_CHECK_M4SUGAR_TEXT, AT_CHECK_M4RE): New macros.
6569 (Standard regular expressions): New test.
6570 (m4_warn, m4_require: circular dependencies, m4_text_wrap): Strip
6571 excess test name quoting.
6572 * tests/semantics.at (AC_CHECK_HEADERS_OLD, AC_CHECK_HEADERS_NEW): Pass
6573 CPPFLAGS to `configure' instead of setting it in `configure'.
6575 * lib/m4sugar/m4sh.m4 (AS_UNAME): Try only /usr/bin/hostinfo, not
6576 any `hostinfo' in $PATH, since hostinfo.exe is a popular file name
6577 on some platforms.
6579 * lib/autoconf/fortran.m4 (AC_LANG(Fortran), AC_FC_SRCEXT):
6580 s/FC_SRCEXT/ac_fc_srcext/; s/FCFLAGS_SRCEXT/ac_fcflags_srcext/.
6582 * tests/local.at (AT_CMP): New macro.
6583 (AT_DATA_AUTOCONF): Do not call AC_PROG_GREP.

6587 (AT_CHECK_MACRO): Run `configure' twice with cache and compare results.
6588 * tests/c.at (Extensions): Do not exit early.

6608 2005-02-03 Paul Eggert <eggert@cs.ucla.edu>
6610 * lib/m4sugar/m4sugar.m4 (m4_re_escape): Escape ?, ^, \, $ too;
6611 this fixes a bug tickled by the AT_CAPTURE_FILE change noted below.
6613 Try not to generated lines of unlimited length, as POSIX places a
6614 2047-byte limit on line length of portable text files.
6615 * lib/autoconf/general.m4 (AC_SUBST, AC_SUBST_FILE):
6616 Use newline as a separator, not space.
6617 * lib/autotest/general.m4 (AT_TESTED, AT_KEYWORDS): Likewise.
6618 (AT_CAPTURE_FILE): Use space-backslash-newline as a separator, not
6619 space.
6621 2005-02-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6623 * lib/m4sugar/m4sh.m4 (_AS_SHELL_FN_WORK): Move func_* to
6624 as_func_*. Add test to check whether positional parameters
6625 are restored after function return.
6627 2005-02-02 Paul Eggert <eggert@cs.ucla.edu>
6629 * doc/autoconf.texi (Special Shell Variables): Mention _,
6630 BIN_SH, DUALCASE. Say that variables other than "status" are safe
6631 if they contain a lower-case letter. The DUALCASE problem was
6632 reported by Ralf Wildenhues.
6634 * bin/autoconf.as: Don't exit with status 0 after write failure
6635 with --help or --version.
6636 * lib/autoconf/general.m4 (_AC_INIT_HELP, _AC_INIT_VERSION): Likewise.

6642 Unicos 9 sed limitations.
6643 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Try cf77 before fort77
6644 to get the option-enhanced interface on older Crays. Try ftn for
6645 Fortran 95 (newer Crays).
6647 2005-02-01 Paul Eggert <eggert@cs.ucla.edu>
6649 * man/Makefile.am (.x.1): Go back to the simple solution, but take
6650 care to echo the commands, so the user knows what's going on.
6651 Modified from a suggestion by Stepan Kasal.
6653 * doc/autoconf.texi (autoreconf Invocation): Mention autopoint,

6660 * doc/install.texi (Defining Variables): Likewise.
6661 Based on a proposed patch by Ralf Wildenhues.
6663 * man/Makefile.am (.x.1): Make sure the required generated files
6664 are up to date. Problem and original solution proposed by Stepan Kasal.
6665 $(dist_man_MANS:.1=-bin-prereq), $(dist_man_MANS:.1=-tests-prereq),
6666 implicit-man-prerequisites): New rules, used by the above.

6672 2005-01-29 Stepan Kasal <kasal@ucw.cz>
6674 Simplify the implementation of m4_require (a.k.a. AC_REQUIRE).
6675 Update the long comment explaining it.
6677 m4_require no longer writes an ``is required by'' line to the
6678 execution stack. It contains only one bit of non-redundant
6679 information: that the macro was required, not called. And even
6680 this bit is useless in most situations: have you ever met a macro
6681 which both calls and requires the same macro?
6683 * lib/m4sugar/m4sugar.m4 (_m4_defun_pro): Don't push a diversion...
6684 (_m4_defun_pro_outer): ... only via this macro, for the outermost
6685 macro.
6686 (_m4_defun_epi, _m4_defun_epi_outer): Complementarily.
6687 (m4_expansion_stack_pop): Remove the misplaced comment.
6688 (m4_require): Don't put the ``is required by'' line to the
6689 execution stack; slightly improve the out-of-a-defun error message.
6690 (_m4_divert_grow): New macro, counter for the temporary diversions.
6691 (_m4_require_call): Use it.
6692 * tests/m4sugar.at (m4_require): Expect output without the
6693 ``is required by'' messages.
6695 2005-01-28 Paul Eggert <eggert@cs.ucla.edu>
6697 * doc/autoconf.texi (Limitations of Usual Tools): Recommend X
6698 rather than x for expr.
6700 * lib/autoconf/lang.m4 (_AC_COMPILER_OBJEXT): Avoid subshells when
6701 this is safe.
6702 * lib/autoconf/programs.m4 (AC_PROG_EGREP, AC_PROG_FGREP): Likewise.
6703 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Likewise.

6712 * doc/make-stds.texi, doc/standards.texi: Update from masters.
6713 * lib/Autom4te/Channels.pm, lib/Autom4te/Configure_ac.pm
6714 * lib/Autom4te/FileUtils.pm, lib/Autom4te/XFile.pm: Update
6715 from masters, so that FileUtils.pm's update_file provide --force
6716 support.
6717 * bin/autoheader.in: Pass $force to update_file so that
6718 config.h.in is always recreated when --force.
6720 2005-01-24 Stepan Kasal <kasal@ucw.cz>
6722 * doc/autoconf.texi (Introduction): Update Peter Simons' address.
6724 2005-01-21 Paul Eggert <eggert@cs.ucla.edu>
6726 * doc/autoconf.texi (Limitations of Builtins): Clarify that
6727 "if test ! -d foo; ..." is portable. Suggested by Stepan Kasal.
6729 2005-01-20 Paul Eggert <eggert@cs.ucla.edu>
6731 * doc/autoconf.texi (Shell Substitutions): Fix typo in case statement.
6732 Warn about newline stripping in `` and $(). Update Solaris
6733 version to 9.
6734 (Limitations of Builtins): Use expr "X...", not expr "x...", as
6735 X insulates us from future changes to Posix.
6736 (Limitations of Usual Tools): For AS_DIRNAME, warn about newline
6737 stripping.
6739 2005-01-19 Stepan Kasal <kasal@ucw.cz>
6741 * doc/autoconf.texi (Defining Symbols): Delete the false comment that
6742 you cannot use AC_DEFINE to define macros containing `[' or `]'.
6744 2005-01-13 Paul Eggert <eggert@cs.ucla.edu>
6746 * doc/autoconf.texi (Limitations of Usual Tools): Document bug

6754 2005-01-05 Paul Eggert <eggert@cs.ucla.edu>
6756 * lib/autoconf/c.m4 (AC_LANG_INT_SAVE(C)): Declare longval and
6757 ulongval to be static, to avoid unwanted GCC warning. Problem
6758 reported by Michael Jennings via Daniel Reed; see
6759 <https://bugzilla.redhat.com/beta/show_bug.cgi?id=143852>.
6761 2005-01-05 Alexandre Duret-Lutz <adl@gnu.org>
6763 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Define datarootdir,
6764 docdir, htmldir, dvidir, pdfdir, psdir, and localdir. Update
6765 datadir, infodir, and mandir. Adjust argument parsing code.
6766 (_AC_INIT_HELP): Update help text.

6768 new variables.
6770 2005-01-04 Noah Misch <noah@cs.caltech.edu>
6772 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): If the Make program does
6773 not seem to work, assume it does set $(MAKE).
6774 * doc/autoconf.texi (AC_PROG_MAKE_SET): Update.
6776 2005-01-03 Stepan Kasal <kasal@ucw.cz>
6778 * lib/m4sugar/m4sh.m4 (AS_REQUIRE): Add a comment about nesting.
6780 2005-01-03 Stepan Kasal <kasal@ucw.cz>
6782 A cleanup of the diversion support in m4sugar.
6784 * lib/m4sugar/m4sugar.m4 (_m4_divert): A typo in description.
6785 (_m4_divert_n_stack): New macro; the expansion is
6786 <newline>m4_divert_stack, if m4_divert_stack is defined, and void
6787 otherwise.
6788 (m4_divert, m4_divert_push, m4_divert_pop, m4_init): Use it.
6789 (m4_divert_push, m4_divert_pop, _m4_defun_epi): Don't expand the word
6790 stored in _m4_divert_diversion or _m4_divert_dump.
6791 (m4_divert_pop): When the parameter is given, compare the symbolic
6792 name with the last diversion pushed on the stack. Previously, the
6793 current diversion was compared with the numeric value of the
6794 diversion given as the parameter.
6795 (m4_require): If the macro hasn't been expanded yet, call ...
6796 (_m4_require_call): this new macro.
6798 2005-01-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6800 * lib/autoconf/general.m4 (_AC_INIT_PREPARE, _AC_ARG_VAR_VALIDATE):

6827 2004-12-30 Noah Misch <noah@cs.caltech.edu>
6829 * bin/autoreconf.in (autoreconf_current_directory): AM_INIT_AUTOMAKE
6830 signals that the package uses Automake; a `Makefile.am' is typical but
6831 not essential. Reported by Magnus Therning.
6832 * tests/torture.at (autoreconf.): New banner.
6833 (autoreconf and non-AC configure): Rename to `Non-Autoconf
6834 AC_CONFIG_SUBDIRS'.

7103 * lib/autoconf/functions.m4 (AC_FUNC_MEMCMP): Use
7104 "char c = '\200';" rather than "char c = 0x80;" as the

7222 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): If xmkmf returns
7223 "/usr/include", clear ac_x_includes instead of leaving it as "no"

7304 * lib/autoconf/general.m4 (_AC_INIT_HELP): Quote $ac_popdir uses.
7305 From Ralf Corsepius in:
7306 http://lists.gnu.org/archive/html/autoconf-patches/2004-08/msg00014.html
7308 2004-08-12 Paul Eggert <eggert@cs.ucla.edu>
7310 * doc/autoconf.texi (Function Portability): Document isinf and
7311 and isnan. From a suggestion by Kevin Ryde.
7313 * lib/Autom4te/General.pm (END): Return correct exit status even
7314 if unlink succeeds and sets $?. Needed with Solaris 8's perl 5.00503.
7316 2004-08-09 Paul Eggert <eggert@cs.ucla.edu>
7318 * tests/torture.at (Deep Package): Use configure.in, not configure.ac,
7319 for compatibility with Automake 1.4. Reported by J C Fitzgerald in
7320 <http://lists.gnu.org/archive/html/bug-autoconf/2003-08/msg00051.html>.
7322 2004-08-04 Alexandre Duret-Lutz <adl@gnu.org>
7324 * lib/autoconf/general.m4 (AC_REQUIRE_AUX_FILE): New empty macro.
7325 (AC_CANONICAL_BUILD): Call it to require config.sub and config.guess.
7326 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Likewise for install-sh.
7327 * doc/autoconf.texi (Input): Document AC_REQUIRE_AUX_FILE.
7328 * lib/autom4te.in (Automake-preselections): Preselect
7329 AC_REQUIRE_AUX_FILE. Automake 1.10 will trace it.
7331 2004-08-02 Alexandre Duret-Lutz <adl@gnu.org>
7333 * lib/autom4te.in (Automake-preselections): Preselect
7334 AC_CANONICAL_BUILD and AC_CANONICAL_TARGET. Automake 1.9.1 will
7335 trace them.
7337 2004-07-29 Paul Eggert <eggert@cs.ucla.edu>
7339 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): Set BIN_SH, for
7340 Tru64.
7341 * doc/autoconf.texi (Shellology): Mention BIN_SH.
7342 Document problem with "`""`" in pdksh POSIX mode.
7344 2004-07-27 Paul Eggert <eggert@cs.ucla.edu>
7346 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): Use "set -o posix"
7347 with pdksh, too. Problem reported by Patrick Welche via
7348 Gary V. Vaughan.
7349 * doc/autoconf.texi (Shellology): Note that set -o posix is
7350 useful for pkdsh, too.
7352 2004-06-24 Paul Eggert <eggert@cs.ucla.edu>
7354 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Require
7355 _AS_UNSET_PREPARE, so that we can use $as_unset directly.
7356 Don't fail if ENV or BASH_ENV is readonly.
7357 (AS_SHELL_SANITIZE): Don't fail if ENV, MAIL, MAILPATH, LC_ALL,
7358 etc. are read only. Problem reported by Ludovic Courtes.
7360 2004-06-23 Noah Misch <noah@cs.caltech.edu>
7362 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): If the shell is
7363 zsh, disable GLOB_SUBST to avoid backslash handling problems.
7364 (trivial change)
7366 2004-06-04 Paul Eggert <eggert@cs.ucla.edu>
7368 * doc/autoconf.texi (File System Conventions): Warn about
7369 names like "aux". Problem reported by Eric Blake.
7371 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY (C)): Use division
7372 by zero instead of array size, so that we can use any arithmetic
7373 constant expression (instead of requiring an integer constant
7374 expression). This allows us to test expressions like DBL_MAX <
7375 LDBL_MAX, which didn't conform to the C standard using the old
7376 method.
7377 (AC_C_LONG_DOUBLE): Put back in the tests for LDBL_MAX and LDBL_EPSILON,
7378 now that we can do floating-point tests at compile time.
7380 2004-06-02 Paul Eggert <eggert@cs.ucla.edu>
7382 * lib/autoconf/c.m4 (AC_C_LONG_DOUBLE): Don't check LDBL_MAX
7383 and LDBL_EPSILON, as the resulting expression isn't an
7384 integer constant expression and violates the C standard.
7385 Problem reported by Nelson H. F. Beebe. Also, check
7386 for "L" suffix, and check that long double doesn't have
7387 worse range or precision than double, that mixed-mode
7388 arithmetic doesn't generate a diagnostic, that double
7389 constants fit in long double.
7391 2004-06-03 Kevin Ryde <user42@zip.com.au>
7393 * doc/autoconf.texi (Function Portability): Add notes on free(NULL),
7394 malloc(0) and realloc(NULL,size).
7396 * doc/autoconf.texi (Shell Substitutions): Spelling error reported by
7397 Bob Proulx.
7399 2004-05-31 Paul Eggert <eggert@cs.ucla.edu>
7401 * lib/autoconf/headers.m4 (HAVE_STDBOOL_H): Detect _Bool bug
7402 in HP aC++/ANSI C B3910B A.05.55 [Dec 04 2003]. Problem reported
7403 by Jim Meyering.
7405 2004-05-26 Paul Eggert <eggert@cs.ucla.edu>
7407 * doc/autoconf.texi (Limitations of Builtins): Mention that ! COMMAND
7408 can be rewritten using if-then-else. Suggested by Bruno Haible.
7410 2004-05-25 Paul Eggert <eggert@cs.ucla.edu>
7412 * doc/autoconf.texi (testsuite Scripts): Fix typo.
7413 Problem reported by Stepan Kasal.
7415 2004-05-24 Paul Eggert <eggert@cs.ucla.edu>
7417 * tests/Makefile.am (autoconfdir): Fix to match comment (trivial
7418 change). Patch reported by Ralf Wildenhues in
7419 <http://mail.gnu.org/archive/html/bug-autoconf/2004-05/msg00092.html>.
7421 * lib/autoconf/functions.m4 (AC_FUNC_MBRTOWC): Don't assume that a
7422 function F exists if the compiler and linker let you compile an
7423 expression like (F != 0). Recent versions of GCC optimize away
7424 the reference to F in that case, since every function address must
7425 be nonzero, so the link succeeds even if F does not exist.
7426 Problem reported by Manu in
7427 <http://mail.gnu.org/archive/html/bug-gnu-utils/2004-05/msg00060.html>.
7429 * doc/autoconf.texi (Systemology): Standardize on the spelling of
7430 "Unix". Many uses changed.
7431 (Limitations of Builtins): Explain better why the ! command isn't
7432 portable.
7434 2004-05-22 Alexandre Duret-Lutz <adl@gnu.org>
7436 * lib/autom4te.in (Automake-preselections): Preselect
7437 LT_SUPPORTED_TAG in lieu of AC_LIBTOOL_TAGS.
7439 2004-05-19 Kevin Ryde <user42@zip.com.au>
7441 * doc/autoconf.texi (Function Portability): Add strerror_r, cross
7442 referencing AC_FUNC_STRERROR_R.
7444 * doc/autoconf.texi (Particular Functions): In AC_FUNC_CLOSEDIR_VOID,
7445 note pessimistic assumption when cross compiling.
7447 2004-05-16 Paul Eggert <eggert@cs.ucla.edu>
7449 * doc/autoconf.texi (Limitations of Make): Note that BSD make
7450 (until 2004) invoked subcommands with sh -e, contra POSIX.
7451 Reported by Kevin Ryde.
7453 2004-05-10 Eric Sunshine <sunshine@sunshineco.com>
7455 * programs.m4 (_AC_PROG_GREP): Fixed bug where PATH argument handed to
7456 _AC_PATH_PROG_FEATURE_CHECK contained leading whitespace (i.e.
7457 " $PATH:/usr/xpg4/bin"). This resulted in bogus tests, such as
7458 `test -f " /usr/bin/grep"', which _always_ failed.
7459 (AC_PROG_SED): Ditto bogus PATH fix.
7460 * autoconf.texi (AC_PROG_GREP): Properly document that this macro
7461 requires that grep correctly supports _multiple_ `-e' options, rather
7462 than stating only that grep should accept `-e'.
7464 2004-05-03 Paul Eggert <eggert@cs.ucla.edu>
7466 Port to C99, which requires that 'exit' be declared.
7468 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Use AC_INCLUDES_DEFAULT
7469 to ensure that stdlib.h is included.
7470 * lib/autoconf/functions.m4 (_AC_LIBOBJ_ALLOCA, AC_FUNC_SETPGRP,
7471 AC_FUNC_STRTOD, AC_FUNC_SETVBUF_REVERSED, AC_FUNC_FORK, _AC_FUNC_FORK,
7472 _AC_FUNC_VFORK, AC_FUNC_WAIT3): Likewise.
7473 * lib/autoconf/specific.m4 (AC_SYS_RESTARTABLE_SYSCALLS): Likewise.
7474 * lib/autoconf/types.m4 (AC_TYPE_GETGROUPS): Likewise.
7475 * lib/autoconf/headers.m4 (AC_HEADER_STDC): Include <stdlib.h>
7476 when using 'exit' in a test; C99 requires that 'exit' be declared.
7478 2004-05-02 Paul Eggert <eggert@cs.ucla.edu>
7480 * doc/autoconf.texi (Particular Programs): AC_PROG_GREP
7481 now prefers 'grep' implementations that accept -e.
7482 (Limitations of Usual Tools): Describe problems of traditional
7483 egrep and fgrep with long input lines, and of traditional grep
7484 with -e.
7485 * lib/autoconf/programs.m4 (AC_PROG_GREP): Check for -e, too.
7486 (_AC_PROG_GREP): Assume 3rd arg is properly quoted for the shell.
7487 All callers changed. Append /usr/xpg4/bin to the PATH, for
7488 Solaris.
7489 (_AC_FEATURE_CHECK_LENGTH): Discard stderr, so we don't bother
7490 the user with complaints about multiple -e options.
7491 * tests/local.at (AC_STATE_SAVE): Use $GREP, not grep.
7492 Define it with AC_PROG_GREP.
7493 * configure.ac (AC_PROG_GREP): Add.
7494 * lib/freeze.mk (GREP): New macro.
7496 2004-05-02 Eric Sunshine <sunshine@sunshineco.com>
7498 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Consult $SHELL as
7499 a possible candidate only after all others fail, rather than
7500 consulting it first. This improves backward compatibility by
7501 better reflecting the way shell selection occurred in previous
7502 versions of Autoconf, and should help to avoid triggering latent
7503 problems in other packages, such as the one in Automake where zsh
7504 is not handled robustly:
7505 http://mail.gnu.org/archive/html/automake/2004-04/msg00095.html
7506 Although it is not Autoconf's responsibility to work around
7507 problems in Automake, it nevertheless makes sense to avoid
7508 introducing unnecessary incompatibilites.
7510 2004-04-22 Albert Chin-A-Young <china@thewrittenword.com>,
7511 Gary V. Vaughan <gary@gnu.org>
7513 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Don't guess
7514 how deeply nested we are when a suitable tool is found, set the
7515 ac_path_TOOL_found flag.
7516 (_AC_PATH_PROG_FEATURE_CHECK): Encapsulate knowledge of how deeply
7517 nested we are in this macro. Break out of all 3 nested loops if
7518 ac_path_TOOL_found is set.
7520 2004-04-21 Gary V. Vaughan <gary@gnu.org>
7522 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Break out
7523 of the _AS_PATH_WALK loop too if GNU flavor is found.
7525 2004-04-21 Alexandre Duret-Lutz <adl@gnu.org>
7527 * doc/autoconf.texi (Limitations of Make): Update documentation
7528 for `$<'. New entry `Long lines', based on a report from Simon
7529 Josefsson. Augment the documentation for SHELL = @SHELL@ with a
7530 paragraph about DJGPP, based on a mail from Richard Dawe.
7532 2004-04-20 Paul Eggert <eggert@twinsun.com>
7534 * tests/c.at (C keywords): Don't assume that GCC supports
7535 "restrict" and "inline", as sufficiently-old GCC versions do not
7536 (also, GCC configured to be in pedantic C89 mode does not).
7537 Problem reported by Sumit Pandya in:
7538 http://mail.gnu.org/archive/html/autoconf/2004-04/msg00092.html
7540 * lib/autoconf/c.m4 (_AC_PROG_CC_G, _AC_PROG_CXX_G): Don't
7541 consider -g to work if it generates warnings when plain compiles
7542 don't. Problem reported by Braden McDaniel in:
7543 http://mail.gnu.org/archive/html/autoconf-patches/2003-07/msg00014.html
7545 * doc/autoconf.texi (Slashes): New section, to document a problem
7546 reported by Jim Meyering in:
7547 http://mail.gnu.org/archive/html/bug-coreutils/2004-02/msg00060.html
7549 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Remove potential
7550 linker output files before linking, to work around IRIX 6 linker bug.
7551 Problem reported by Rainer Orth in:
7552 http://mail.gnu.org/archive/html/autoconf-patches/2004-02/msg00007.html
7554 2004-04-20 Gary V. Vaughan <gary@gnu.org>
7556 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Make the
7557 best tool so far counter rely on the tool path variable name to
7558 avoid checks for one tool being affected by the results of running
7559 the length check on a previous tool.
7561 * lib/autoconf/programs.m4 (_AC_PROG_GREP): Take an additional
7562 match expression argument, as different greps have different
7563 regular expression flavours.
7564 (AC_PROG_FGREP): Pass 'FGREP'. fgrep treats all match chars as
7565 literals.
7566 (AC_PROG_EGREP): Pass 'EGREP$'.
7567 (AC_PROG_GREP): Pass 'GREP$'.
7569 2004-04-20 Albert Chin-A-Young <china@thewrittenword.com>
7571 * lib/autoconf/programs.m4 (AC_PROG_GREP): Cache variable
7572 is `ac_cv_path_GREP', not `oc_cv_path_GREP'.
7574 2004-03-29 Paul Eggert <eggert@twinsun.com>
7576 * doc/autoconf.texi (Particular Headers, Particular Types, Generic
7577 Types, Specific Compiler Characteristics, System Services,
7578 Obsolete Macros): Use 'long int', 'short int', 'unsigned int'
7579 etc. consistently instead of 'long', 'short', 'unsigned' etc.
7580 * lib/autoconf/c.m4 (AC_LANG_INT_SAVE(C), AC_C_BIGENDIAN): Likewise.
7581 * lib/autoconf/functions.m4 (AC_FUNC_MMAP, AC_FUNC_SELECT_ARGTYPES):
7582 Likewise.
7583 * lib/autoconf/headers.m4 (AC_HEADER_SYS_WAIT): Likewise.
7584 * lib/autoconf/types.m4 (AC_TYPE_GETGROUPS, AC_TYPE_SIZE_T,
7585 AC_TYPE_OFF_T): Likewise.
7586 * tests/semantics.at (AC_CHECK_TYPES: backward compatibility):
7587 Likewise.
7589 * tests/foreign.at (Libtool): Create an empty aclocal.m4, to
7590 pacify libtool 1.5.2. Fix quoting problems in sed command.
7592 2004-03-28 Paul Eggert <eggert@twinsun.com>
7594 * doc/autoconf.texi (Particular Structures): AC_STRUCT_TIMEZONE
7595 now defines HAVE_DECL_TZNAME if it is declared, when
7596 HAVE_STRUCT_TM_TM_ZONE is not defined.
7597 * lib/autoconf/types.m4 (AC_STRUCT_TIMEZONE): Implement this.
7598 Do not assume atoi. Rely on HAVE_DECL_TZNAME when testing
7599 for HAVE_TZNAME.
7601 2004-03-28 Steven G. Johnson <stevenj@fftw.org>
7603 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Corrected
7604 superfluous backslashing of quotes (") in sed expressions;
7605 thanks to Paul Eggert.
7607 2004-03-26 Steven G. Johnson <stevenj@alum.mit.edu>
7609 * lib/autoconf/fortran.m4 (_AC_PROG_FC): new name of Intel
7610 Fortran compiler is ifort, also added pghpf; thanks to Nelson
7611 H. F. Beebe for the bug report.
7613 2004-03-26 Steven G. Johnson <stevenj@fftw.org>
7615 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): fix for
7616 quoted -cmdline argument in Portland Group compiler (bug
7617 reported by Jeffrey J. Barteet).
7619 2004-03-25 Kevin Ryde <user42@zip.com.au>
7621 * doc/autoconf.texi (Specifying Names): Move cross_compiling ovindex to
7622 (Run Time): ... here, where it's now mentioned.
7624 2004-03-19 Alexandre Duret-Lutz <adl@gnu.org>
7626 * doc/autoconf.texi (autom4te Invocation): Language Autoconf
7627 inherits from language Autoconf-without-aclocal-m4.
7628 (Customizing autom4te): Adjust example; the cache must now be
7629 disabled for language Autoconf-without-aclocal-m4.
7631 2004-03-16 Paolo Bonzini <bonzini@gnu.org>
7632 Nathanael Nerode <neroden@twcny.rr.com>

7635 AC_CHECK_TOOLS): Warn if a cross-tool is found without
7636 a prefix.
7637 (AC_PATH_TARGET_TOOL, AC_CHECK_TARGET_TOOL,

7639 * doc/autoconf.texi (Generic Programs): Document
7640 (AC_PATH_TARGET_TOOL, AC_CHECK_TARGET_TOOL,
7641 AC_CHECK_TARGET_TOOLS, and warn for future changes
7642 in the behavior of AC_PATH_TOOL, AC_CHECK_TOOL and
7643 AC_CHECK_TOOLS.
7644 (Specifying Names): Document the reason for these future
7645 behavioral changes.
7646 * tests/mktests.sh: Do not generate tests for the
7647 new macros.
7648 * NEWS: Document these changes.
7650 * doc/autoconf.texi: Avoid macros with unbraced arguments,
7651 they make TeX hang up.
7653 2004-03-15 Paul Eggert <eggert@bogus.example.com>
7655 * NEWS: New macro AC_CHECK_ALIGNOF.
7656 * doc/autoconf.texi (Generic Compiler Characteristics): Document it.
7657 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Use long int rather than
7658 int; avoid "a `$1'" since this isn't grammatical if $1 begins with a
7659 vowel.
7660 (AC_CHECK_ALIGNOF): New macro.
7661 * tests/mktests.sh (ac_exclude_list): Exclude AC_CHECK_ALIGNOF.
7662 * tests/semantics.at (AC_CHECK_ALIGNOF): Add tests similar to
7663 those for sizeof.
7665 2004-03-03 Paul Eggert <eggert@twinsun.com>
7667 * bin/Makefile.am (edit): Don't use $< in a context where
7668 POSIX doesn't require support for it. Use $@.in instead.
7669 Problem reported by Anthony N. Frasso in
7670 <http://mail.gnu.org/archive/html/autoconf/2004-03/msg00008.html>.
7671 * bin/autoscan.in, bin/autoupdate.in: Add @configure_input@ comment.
7673 2004-02-23 Gary V. Vaughan <gary@gnu.org>
7675 * bin/autoreconf.in (autoreconf_current_directory): Recognize LT_INIT
7676 from the next generation of Libtool.
7677 * lib/autom4te.in (Autoreconf-preselections): Ditto.
7679 2004-02-20 Alexandre Duret-Lutz <adl@gnu.org>
7681 * doc/autoconf.texi (Limitations of Usual Tools) <mkdir>: `mkdir -p'

7684 2004-02-18 Paul Eggert <eggert@twinsun.com>
7686 Fix a dependencies problem, stemming from a Autoconf 2.59 build
7687 problem on QNX reported by Stephen Rasku in
7688 <http://mail.gnu.org/archive/html/bug-autoconf/2004-02/msg00066.html>.
7690 * bin/Makefile.am ($(srcdir)/autoconf.in): Depend on
7691 $(m4sh_m4f_dependencies); this removes a FIXME.
7692 * tests/Makefile.am ($(srcdir)/wrapper.in): Likewise.
7693 (MAINTAINERCLEANFILES): Split into pieces,
7694 one per related section. Add $(srcdir)/wrapper.in.
7696 2004-02-09 Paul Eggert <eggert@twinsun.com>
7698 * doc/autoconf.texi (Setting Output Variables): Emphasize that
7699 AC_SUBST provides no portable way to escape literal newlines.
7701 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS): Ignore all
7702 flags of the form -lcrt*.o, not just -lcrt[01].o and -lcrtbegin.o.
7703 Darwin uses -lcrt2.o and there's little point to cataloging all
7704 the system variants. Partial fix reported by Andreas Waechter in:
7705 http://mail.gnu.org/archive/html/autoconf-patches/2004-02/msg00006.html
7706 for bug reported by Nelson H. F. Beebe in:

7714 acobsolete.m4, suggested by Alexandre Duret-Lutz.
7716 2004-02-02 Paolo Bonzini <bonzini@gnu.org>
7718 * bin/autoupdate.in: Define __file__ so that warnings
7719 refer to the correct file.
7720 * doc/autoconf.texi (AU_DEFUN): Describe more correctly
7721 the behavior of the third argument.
7722 * lib/autoconf/autoupdate.m4 (AU_DEFUN): Describe more
7723 correctly the behavior of the third argument. Document
7724 what the three macros that AU_DEFUN defines do. Fix
7725 warning message when the third argument includes $0
7726 (reported by Alexandre Duret-Lutz).
7728 2004-01-30 Paolo Bonzini <bonzini@gnu.org>
7729 Eric Sunshine <sunshine@sunshineco.com>
7730 Paul Eggert <eggert@twinsun.com>
7732 * lib/m4sugar/m4sh.m4 (M4SH-SANITIZE): New diversion.
7733 (AS_INIT): Output shell initialization there. Removed optional
7734 parameter. Expand _AS_SHELL_FN_SPY.
7735 (AS_INIT_WITH_SHELL_FN): Removed.
7736 (_AS_SHELL_FN_SPY): New macro.
7737 (AS_DETECT_REQUIRED, AS_DETECT_SUGGESTED): New
7738 macros.
7739 (AS_SHELL_SANITIZE): Remove loop to find better shell
7740 and documentation for the parameter.
7741 (_AS_DETECT_BETTER_SHELL): Move it here.
7742 (_AS_SHELL_FN_WORK): Remove shell invocation, reformat.
7743 (_AS_RUN): Move it here, support testing with eval.
7744 (AS_REQUIRE_SHELL_FN): Require shell functions when
7745 it is used.
7746 (_AS_LINENO_WORKS): Put around braces, we do not
7747 trigger the bash bug anymore.
7748 * lib/autotest/general.m4: Document M4SH-SANITIZE, do not
7749 use AS_INIT_WITH_SHELL_FN.

7758 (AU_DEFUN): Honor the third parameter, create autoupdate
7759 macros with AU_DEFINE.
7760 * lib/autoconf/headers.m4 (AC_USG, AC_MEMORY_H,
7761 AC_DIR_HEADER): Use AU_DEFUN's third parameter.
7762 * lib/autoconf/lang.m4 (AC_LANG_SAVE): Likewise.

7769 * lib/autoconf/status.m4: Remove FIXME.

7780 * lib/autoconf/general.m4 (_AC_INIT_COPYRIGHT): Add 1992 thorugh
7781 2003 (except 1997) to the list of copyright years. This undoes
7782 the 2003-05-22 change, which removed the older years from the list.
7783 * lib/autoconf/status.m4 (AC_OUTPUT): Update copyright date to 2004.
7785 2004-01-27 Gary V. Vaughan <gary@gnu.org>
7786 Albert Chin-A-Young <china@thewrittenword.com>

7790 possible.
7791 * lib/autoconf/programs.m4 (_AC_PROG_GREP): Factor out the core of
7792 AC_PROG_GREP.
7793 (AC_PROG_EGREP, AC_PROG_FGREP): Use it to find best available
7794 egrep and fgrep respectively if $GREP -E/-F don't work.
7795 (_AC_PATH_PROG_FEATURE_CHECK): Factor out the common core of
7796 _AC_PROG_GREP, and AC_PROG_SED.
7797 (_AC_FEATURE_CHECK_LENGTH): New helper macro for finding the
7798 longest input length accepted by a command.
7799 (AC_PROG_SED): Use it.
7800 * doc/autoconf.texi (Particular Programs): Document the changes.
7801 * NEWS: Updated.
7803 2004-01-27 Paul Eggert <eggert@twinsun.com>
7805 * bin/autoconf.as ($version): Update copyright from 2003 to 2004.

7807 bin/autoscan.in, bin/autoupdate.in, bin/ifnames.in: Likewise.
7808 * lib/autoconf/general.m4 (_AC_INIT_COPYRIGHT): Likewise.
7810 * Makefile.in, aclocal.m4, configure, bin/Makefile.in,
7811 bin/autoconf.in, config/Makefile.in, config/config.guess,
7812 config/config.sub, config/install-sh, config/mdate-sh,

7827 2004-01-26 Paul Eggert <eggert@twinsun.com>
7829 * doc/autoconf.texi (Default Includes): Include <stdint.h> even if
7830 HAVE_INTTYPES_H is defined. This is needed on Tru64 5.1b with
7831 Compac C V6.5-207 (dtk), which defines uintmax_t in <stdint.h> but
7832 not <inttypes.h>. Problem reported by Tim Mooney in
7833 <http://mail.gnu.org/archive/html/bug-coreutils/2004-01/msg00147.html>.
7834 * lib/autoconf/headers.m4 (_AC_INCLUDES_DEFAULT_REQUIREMENTS):
7835 Likewise.
7837 * lib/autoconf/programs.m4 (AC_PROG_SED): Use diff, not sed;
7838 otherwise "make check" fails because it forbids cmp (I guess
7839 because cmp treats files as binary on DOS-like systems).
7841 * tests/mktests.sh: Update copyright date to 2004, since some tests
7842 have changed in 2004.
7844 2004-01-23 Gary V. Vaughan <gary@gnu.org>

7847 non-truncating sed or gsed program in PATH.
7848 * tests/acprograms.at: Add it.
7849 * doc/autoconf.texi (Particular Programs): Document it.
7850 * NEWS: Updated.
7852 2004-01-15 Paul Eggert <eggert@twinsun.com>
7854 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Try -std, not -std1, since
7855 -std1 disables some useful extensions on Tru64. Problem reported
7856 by N. Lichtmaier in
7857 <http://mail.gnu.org/archive/html/autoconf/2004-01/msg00100.html>.
7859 2004-01-14 Paul Eggert <eggert@twinsun.com>
7861 * doc/autoconf.texi (Programming in M4sh): Document that
7862 AS_MKDIR_P succeeds if the destination is a symbolic link
7863 to an existing directory.
7864 (Limitations of Usual Tools): Note that mkdir -p might not
7865 succeed on symlinks to directories.
7867 2004-01-13 Paul Hilfinger <hilfinger@CS.Berkeley.EDU>
7869 * lib/autoconf/autoupdate.m4 (AU_DEFUN): Grammar fix in comment.
7870 * bin/autoheader.in: Grammar fix in message.
7871 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P):
7872 Test for dir before calling mkdir -p. (trivial changes)
7874 2004-01-13 Eric Blake <ebb9@byu.net>
7876 * doc/autoconf.texi (Obsolete Macros): In AC_TRY_COMPILE and
7877 AC_TRY_LINK, s/AC_LANG_SOURCE/AC_LANG_PROGRAM/. (trivial change)
7879 2004-01-10 Jim Meyering <jim@meyering.net>
7881 * doc/autoconf.texi (Running the Preprocessor): Correct grammar.
7883 2004-01-09 Paul Eggert <eggert@twinsun.com>
7885 * lib/autoconf/general.m4: Fix bug: AC_CHECK_SIZEOF evokes a warning
7886 with `autoconf -Wall,error'. Bug reported by Eric Blake in:
7887 http://mail.gnu.org/archive/html/autoconf-patches/2004-01/msg00000.html
7888 (_AC_COMPUTE_INT_COMPILE): Invoke _AC_COMPILE_IFELSE, not
7889 AC_COMPILE_IFELSE, since we now assume our caller invokes
7890 AC_LANG_COMPILER_REQUIRE, for symmetry with _AC_COMPUTE_INT_RUN.
7891 (_AC_COMPUTE_INT_RUN): Likewise, for _AC_RUN_IFELSE instead
7892 of AC_RUN_IFELSE; this avoids the warning mentioned above.
7893 (_AC_COMPUTE_INT): Invoke AC_LANG_COMPILER_REQUIRE.
7895 2004-01-07 Paul Eggert <eggert@twinsun.com>
7897 * lib/autoconf/general.m4 (_AC_LIBOBJS_NORMALIZE): Avoid \$ inside
7898 `"'...'"`, as it's confusing (and I suspect it may not work on
7899 some platforms). The code was incorrect anyway, as it assumed
7900 that \$ evaluated to itself in that context. Reported by
7901 Alexandre Duret-Lutz.
7903 2004-01-07 Alexandre Duret-Lutz <adl@gnu.org>
7905 * lib/autom4te.in (Automake-preselections): Preselect AC_LIBTOOL_TAGS
7906 and _LT_AC_TAGCONFIG.

7910 * doc/autoconf.texi (One Macro Call): Fix an incorrect
7911 example, and add more examples. Reported by Eric Sunshine.
7913 2004-01-05 Paul Eggert <eggert@twinsun.com>
7915 * doc/autoconf.texi (Limitations of Usual Tools):
7916 Remove warning against "rm -fr" introduced yesterday; it
7917 was a false alarm.
7919 * bin/Makefile.am (autoconf, autoheader, autom4te, autoreconf,
7920 autoscan, autoupdate, ifnames): Don't use chmod -w.
7921 * lib/Makefile.am (autom4te.cfg): Likewise.
7922 * doc/autoconf.texi (Limitations of Usual Tools): Warn against
7923 "chmod -w".
7925 2004-01-04 Paul Eggert <eggert@twinsun.com>
7926 Paolo Bonzini <bonzini@gnu.org>
7928 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Speed up sed scripts
7929 by doing lineno substitution only on lines containing "$LINENO".
7931 2004-01-04 Paul Eggert <eggert@twinsun.com>
7933 * lib/autoconf/general.m4 (AC_ARG_PROGRAM):
7934 Use "rm -f" to remove conftest.sed, not plain "rm".
7935 Bug reported by David Relson in
7936 <http://mail.gnu.org/archive/html/autoconf/2004-01/msg00011.html>.
7938 * Makefile.am (autom4te-update):
7939 Replace "rm -rf" and "rm -fr" with "rm -f -r", as POSIX requires.
7940 * Makefile.maint (my-distcheck, do-po-update): Likewise.
7941 * doc/autoconf.texi (Guidelines): Likewise.
7942 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Likewise.

7947 * tests/Makefile.am (clean-local): Likewise.
7948 * tests/tortue.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS,
7949 srcdir): Likewise.
7950 * doc/autoconf.texi (Limitations of Usual Tools):
7951 Warn against "rm -fr".
7953 2004-01-03 Paul Eggert <eggert@twinsun.com>
7955 * doc/autoconf.texi (Limitations of Usual Tools): Mention that cc
7956 -c -o might not work. From a suggestion by Kevin Ryde.
7957 (C Compiler, Generating Sources, Limitations
7958 of Usual Tools, Limitations of Make, Making testsuite Scripts):
7959 Don't put '-o' after non-options, as POSIX doesn't allow this.
7960 Mention that cc's name might be gcc or c89 or whatever.
7962 2004-01-04 Kevin Ryde <user42@zip.com.au>
7964 * doc/autoconf.texi: Add various further index entries.
7966 2003-12-29 Paul Eggert <eggert@twinsun.com>
7968 * bin/autoreconf.in (autoreconf_current_directory):
7969 Fix typo: mkdir without umask arg.
7971 2003-12-27 Alexandre Duret-Lutz <adl@gnu.org>
7973 * doc/autoconf.texi (Limitations of Make) <Automatic rule rewriting>:
7974 Documents OSF1/Tru64 make behavior. Replace `VPATH = ../src' by
7975 `VPATH = ../pkg/src' in examples to make the OSF1/Tru64 make
7976 explanation clearer.
7978 2003-12-24 Andreas Schwab <schwab@suse.de>
7980 * doc/autoconf.texi (Default Includes): Fix misspelling of
7981 AC_INCLUDES_DEFAULT.
7983 2003-12-03 Paolo Bonzini <bonzini@gnu.org>
7985 * configure.ac: Test if sh -n works.
7986 * configure: Regenerate.
7987 * tests/atlocal.in: Store the result here.
7988 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Extracted from
7989 tools.at, looking in atlocal's ac_cv_sh_n_works instead
7990 of explicitly testing.
7991 (AT_CHECK_PERL_SYNTAX): Moved from tools.at.
7992 (AT_CHECK_AUTOCONF): Test for the configure script syntax.
7993 * tests/tools.at (Syntax of the shell scripts): Simplify
7994 using AT_CHECK_SHELL_SYNTAX.

8007 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE):
8008 Extracted from AS_SHELL_SANITIZE.
8009 (_AS_SHELL_FN_WORK, AS_INIT_WITH_SHELL_FN): New
8010 macros.
8011 (AS_SHELL_SANITIZE): Move reinvocation code from
8012 _AS_LINENO_WORKS, use it to find out if shell
8013 functions work.
8014 (_AS_LINENO_WORKS): Don't find another shell if $LINENO
8015 does not work.
8016 (AS_INIT): Pass parameter down to AS_SHELL_SANITIZE.

8031 them on the fly.
8033 2003-11-24 Akim Demaille <akim@epita.fr>
8035 * doc/autoconf.texi (Particular Programs): AC_PROG_LEX can

8078 * doc/autoconf.texi (Using System Type): Revise, showing $host rather
8079 than $target since the latter is not usual, add guidelines on when to
8080 use or not use the system type.

8084 * doc/autoconf.texi (Limitations of Usual Tools): Fix what looks like a

8161 2003-10-28 Akim Demaille <akim@epita.fr>
8163 * Makefile.cfg (local_updates, executable-update): Tweak to be

8192 * lib/autoconf/general.m4 (_AC_LINK_IFELSE, _AC_COMPILE_IFELSE):

8237 2003-10-13 Nathanael Nerode <neroden@gcc.gnu.org>
8239 * lib/autoconf/functions.m4 (AC_FUNC_FORK): Trivial fix for vfork
8240 cross test.

8250 --help output.
8251 * bin/ifnames.in: Likewise.
8253 2003-10-09 Paul Eggert <eggert@twinsun.com>
8255 * lib/Autom4te/XFile.pm: Don't assume -j is solo.
8256 Issue a more-informative diagnostic.
8257 Problems reported by Eric Sunshine.
8259 2003-10-08 Steven G. Johnson <stevenj@alum.mit.edu>
8261 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Omit quoted
8262 -mGLOB_options_string stuff for Intel ifc, which can cause
8263 _AC_FC_LIBRARY_LDFLAGS to fail. Use (faster) case for
8264 pattern-matching instead of grep.
8266 2003-10-08 Steven G. Johnson <stevenj@alum.mit.edu>
8268 * doc/autoconf.texi: Document new FC Fortran macros.
8270 2003-10-08 Gary V. Vaughan <gary@gnu.org>
8272 * lib/autoconf/general.m4 (AC_CONFIG_MACRO_DIR): Stub out a macro
8273 that future autopoint/aclocal/automake/autoreconf will be able
8274 to trace to find where to install local m4 macros.
8275 * doc/autoconf.texi (Input): Document it.
8276 * NEWS: Updated.

8282 -lcrt[01].o.
8284 2003-10-04 Steven G. Johnson <stevenj@ab-initio.mit.edu>
8286 * lib/autoconf/fortran.m4 (_AC_PROG_FC_G): Use language-specific
8287 cache variable instead of $G77 to decide whether to include -O2,
8288 since $G77 is specific to Fortran 77.
8290 2003-10-03 Steven G. Johnson <stevenj@alum.mit.edu>
8292 * lib/autoconf/fortran.m4 (AC_FC_FREEFORM): Support Absoft "-f
8293 free" flag. Re-order flags tested into rough order of popularity.
8295 2003-10-03 Steven G. Johnson <stevenj@alum.mit.edu>
8297 * lib/autoconf/fortran.m4 (AC_PROG_FC): Reverse the order of the
8298 arguments so that it can be used with syntax identical to
8299 AC_PROG_F77, and so that we can more easily decide to
8300 remove/deprecate the DIALECT optional argument in the future if it
8301 proves troublesome.
8302 (AC_FC_FREEFORM): Exit 77 upon failure to fix test suite for
8303 non-freeform-supporting compilers. Document freeform flags.
8305 2003-10-03 Akim Demaille <akim@epita.fr>
8307 * configure.ac: Look for emacs, not macs.
8308 Reported by Eric Sunshine.
8310 2003-10-03 Akim Demaille <akim@epita.fr>
8312 * lib/autom4te.in (Autoreconf-preselections): Trace AC_CONFIG_AUX_DIR.
8313 * bin/autoreconf.in (autoreconf_current_directory): Create the
8314 AUX_DIR if needed, for sake of automake --add-missing etc.
8315 Suggested by Alexandre Duret-Lutz.
8317 2003-10-03 Akim Demaille <akim@epita.fr>
8319 * configure.ac: Quotation and formatting changes.
8320 (EMACS): Don't set it if it is not recent enough to support

8346 * config/announce-gen (&print_news_deltas): Extracted from...
8347 (&print_changelog_deltas): here.

8353 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Remove files which might
8354 have been created when invoking the compiler.

8366 Problem reported by Lars J. Aas in
8367 <http://mail.gnu.org/archive/html/autoconf/2003-07/msg00042.html>.
8368 (_AS_MKDIR_P_PREPARE): Change "rm -fr ./-p" to the more-conservative
8369 "test -d ./-p && rmdir ./-p". Suggested by Andreas Schwab in:
8370 http://mail.gnu.org/archive/html/autoconf-patches/2003-09/msg00039.html
8372 2003-09-26 Akim Demaille <akim@epita.fr>
8374 * lib/autoconf/status.m4 (_AC_OUTPUT_COMMANDS): Make sure the
8375 directory for AC_CONFIG_COMMANDS' first argument exists.
8376 This makes valid the invocation of _AC_SRCPATH that follows.
8377 Reported by Eric Sunshine.
8378 * doc/autoconf.texi (Configuration Commands): Adjust.
8380 2003-09-26 Akim Demaille <akim@epita.fr>
8382 * bin/autoscan.in (Autom4te::FileUtils): Use it for find_file.
8383 Reported by Ralf Corsepius.
8385 2003-09-26 Akim Demaille <akim@epita.fr>
8387 * lib/autoconf/general.m4 (AC_HELP_STRING): Don't overquote the
8388 arguments.
8389 Actually, use AU_ALIAS.
8390 From Bruno Haible.
8392 2003-09-26 Paul Eggert <eggert@twinsun.com>
8394 * lib/m4sugar/m4sh.m4 (_AS_MKDIR_P_PREPARE): If mkdir -p . fails,
8395 rm -fr ./-p to remove junk left behind on NextStep and OpenStep.

8399 2003-09-26 Akim Demaille <akim@epita.fr>
8401 The test suite are sometimes assigning timings incorrectly.
8402 Reported by Henk Krus.
8403 Diagnosed by Nicolas Joly.
8405 * lib/autotest/general.m4 (AT_CLEANUP): Rename AT_help as
8406 AT_help_all.
8407 Instead of making AT_help a sequence of assignments to grow
8408 $at_help_all, just make AT_help_all be the growing contents of
8409 $at_help_all, and make a single assignment in...
8410 (AT_INIT): here.
8411 (at_times_skip): Flip the meaning and rename as...
8412 (at_times_p): this.
8413 (AT_INIT): When summarizing the test that ran, remove
8414 $at_times_file after use, and check it is present before trying to
8415 use it.
8417 2003-09-25 Akim Demaille <akim@epita.fr>
8419 Version 2.57d.
8421 * bin/Makefile.am (edit): Handle '@configure_input@'.
8422 (autoconf, autoheader, autom4te, autoreconf, autoscan, autoupdate)
8423 (ifnames): chmod -w.
8424 * tests/wrapper.as (AUTOCONF, AUTOM4TE, ): Point to tests/
8425 executables, not bin/ executables! Otherwise all the magic needed
8426 to find non installed files is turned off. This caused a failure
8427 of test 40 and 41 that ran aclocal 1.8 which in turn ran autom4te
8428 as found in its environment (sent by tests/autoreconf): pointing
8429 to bin/autom4te that could not find its files.
8430 * tests/mktests.sh: Force the replacement of generated files, for
8431 the sake of "mv" program that are interactive when overwriting a
8432 -w file.
8433 * config/install-sh: Upgrade from CVS Automake.
8435 2003-09-23 Paul Eggert <eggert@twinsun.com>
8437 * doc/autoconf.texi (Limitations of Builtins): Document test -h
8438 versus test -L issues.
8440 2003-09-23 Daniel Jacobowitz <drow@mvista.com> and
8441 Paul Eggert <eggert@twinsun.com>
8443 Trivial change to support GCC's configuration procedure.
8444 * lib/autoconf/c.m4 (AC_PROG_CPP_WERROR): New macro.
8445 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): Don't warn
8446 about inconsistency if the preprocessor is set to give errors for
8447 any warning.
8448 * doc/autoconf.texi (C Compiler Characteristics): Document this.
8450 2003-09-13 Alexandre Duret-Lutz <adl@gnu.org>
8452 * Makefile.am (autom4te-update, autom4te_files): Fetch Struct.pm

8464 from masters.
8466 2003-09-12 Akim Demaille <akim@epita.fr>
8468 * doc/autoconf.texi (Header Portability): Promote linux/types.h,
8469 not asm/types.h.
8471 2003-09-11 Akim Demaille <akim@epita.fr>
8473 * doc/autoconf.texi (Header Portability): linux/random.h.
8474 From Peter Hendrickson.
8476 2003-09-10 Akim Demaille <akim@epita.fr>
8478 * tests/mktests.sh (au_exclude_egrep): Make it harder to be
8479 willing to edit the output files.
8481 2003-09-10 Akim Demaille <akim@epita.fr>
8483 * tests/fortran.at (GNU Fortran 77): Also exercise AC_FC_SRCEXT
8484 and AC_FC_FREEFORM.
8485 * tests/mktests.sh: Skip AC_FC_SRCEXT.
8486 * lib/autoconf/fortran.m4 (AC_FC_SRCEXT, AC_FC_FREEFORM): Likewise.
8488 2003-09-09 Akim Demaille <akim@epita.fr>

8497 trailing files.
8499 2003-09-07 Paul Eggert <eggert@twinsun.com>
8501 * lib/autoconf/specific.m4 (AC_SYS_RESTARTABLE_SYSCALLS):
8502 Improve the accuracy of the wording about obsolescence.
8503 From a suggestion by Ian Lance Taylor in
8504 <http://mail.gnu.org/archive/html/autoconf/2003-09/msg00044.html>.
8506 2003-09-05 Paul Eggert <eggert@twinsun.com>
8508 * lib/autoconf/fortran.m4 (AC_FC_FREEFORM): Try -ffree-form too,
8509 for the benefit of g77 3.2. Fix suggested by Steven G. Johnson.
8511 2003-09-04 Akim Demaille <akim@epita.fr>
8513 * tests/mktests.sh (ac_exclude_list): Fix the filtering of
8514 AC_FUNC_WAIT3.
8516 2003-09-04 Akim Demaille <akim@epita.fr>
8518 * bin/autom4te.in: Use &fatal where more appropriate than &error.
8519 (freeze): When exiting, use $exit_code.
8520 * lib/autoconf/fortran.m4: Comment changes.
8522 2003-09-04 Akim Demaille <akim@epita.fr>
8524 * tests/mktests.sh (ac_exclude_list): Add AC_FC_FUNC.
8526 2003-09-02 Steven G. Johnson <stevenj@alum.mit.edu>
8528 Add support for newer Fortran dialects. The F77 interface is
8529 unchanged, and continues to support Fortran 77. New FC macros
8530 correspond to all the old F77 macros, with output variables FC,
8531 FCFLAGS, and FCLIBS. AC_PROG_FC defaults to picking the newest
8532 available dialect, but older dialects can be specified. There are
8533 new macros AC_FC_SRCEXT to set the source extension, and
8534 AC_FC_FREEFORM to accept free-form source files.
8536 * lib/autoconf/c.m4 (_AC_LANG_PREFIX(C), _AC_LANG_PREFIX(C++)):
8537 New macros.
8538 (AC_LANG_PROGRAM(C)): Invoke _AC_LANG_PROGRAM_C_FC_HOOKS if defined.
8539 * lib/autoconf/fortran.m4 (AC_LANG(Fortran), _AC_FORTRAN_ASSERT,

8549 _AC_FC_WRAPPERS, AC_FC_WRAPPERS, _AC_FC_FUNC, AC_FC_FUNC,
8550 AC_FC_SRCEXT, AC_FC_FREEFORM):
8551 New macros.
8552 (AC_PROG_F77, AC_PROG_F77_C_O, AC_F77_LIBRARY_LDFLAGS,
8553 AC_F77_DUMMY_MAIN, AC_F77_MAIN, _AC_F77_NAME_MANGLING,
8554 AC_F77_NAME_MANGLING, AC_F77_WRAPPERS, AC_F77_FUNC):
8555 Rewrite in terms of the above.
8556 (_AC_PROG_F77_G, _AC_PROG_F77_V_OUTPUT, _AC_PROG_F77_V): Remove.
8557 * lib/autoconf/lang.m4 (_AC_LANG_PREFIX): New macro.
8558 * tests/acfortran.at: Test AC_FC_FREEFORM, AC_FC_FUNC,
8559 AC_FC_MAIN, AC_FC_SRCEXT, AC_FC_WRAPPERS, AC_PROG_FC_C_O.
8561 2003-09-02 Paul Eggert <eggert@twinsun.com>
8563 * doc/autoconf.texi (Limitations of Usual Tools, Limitations of Make):
8564 Document problems with timestamp resolution that 'make', 'cp -p', and
8565 'touch -r' have.
8567 2003-08-27 Akim Demaille <akim@epita.fr>
8569 * tests/m4sugar.at (cross_warning): Make sure to enable the
8570 output, so that we can track spurious m4sugar output.
8571 * tests/local.at: Require 2.57.
8572 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): Don't m4_default the arguments that
8573 are defaulted by AT_CHECK anyway.
8574 Use AT_CHECK_AUTOM4TE.
8575 * lib/m4sugar/m4sugar.m4: There should be no output at all: add a
8576 missing dnl.
8578 2003-08-27 Akim Demaille <akim@epita.fr>
8580 * bin/autoheader.in: Issue the "Using auxiliary..." message only
8581 when -Wobsolete is set.
8582 Set it on by default.
8583 Suggested by Klee Dienes.
8585 2003-08-27 Akim Demaille <akim@epita.fr>

8634 * bin/autom4te.in: Adjust to output the call stack.
8635 * tests/m4sugar.at (m4@&t@_warn): Adjust.
8637 2003-08-22 Akim Demaille <akim@epita.fr>
8639 * lib/Autom4te/Request.pm, lib/Autom4te/C4che.pm: New.
8640 * bin/autom4te.in: Adjust.
8642 2003-08-21 Akim Demaille <akim@epita.fr>
8644 * lib/Autom4te/General.pm (&file_name_is_absolute): Remove.
8645 (&verbose): Remove.
8646 (&getopt): Adjust the note and verb channels, depending upon
8647 --verbose.
8648 * bin/autoheader.in, bin/autom4te.in, bin/autoscan.in,
8649 * bin/autoupdate.in: Adjust.
8650 Use &verb, not &verbose.

8654 * bin/autoheader.in (&parse_args): Use &parse_warnings and
8655 &parse_WARNINGS.
8656 ($help): Use Autom4te::ChannelDefs::usage.
8657 * bin/autoscan.in: Use Autom4te::ChannelDefs.
8658 * lib/Autom4te/General.pm: Don't export error: you don't own it.
8660 2003-08-21 Akim Demaille <akim@epita.fr>
8662 First stab at preserving warnings between calls to autom4te,
8663 including when the cache is used.
8665 There are still several issues: (i) there are too many runs of m4
8666 (one for include, one for warnings, and some more), (ii) warnings
8667 spreading on several lines are not handled gracefully, (iii) the
8668 code meant to have the call stack display for errors does not work
8669 (its handling should move from m4 to autom4te).
8671 * bin/autom4te.in Autom4te::Channels, Autom4te::ChannelDefs):
8672 Use them.
8673 (@preselect): Add m4_warn.
8674 ($exit_status): Remove, use $exit_code.
8675 ($help): Use Autom4te::ChannelDefs::usage.
8676 (&handle_m4): No longer define the m4_warnings.
8677 At each run, extract and report the warnings.
8678 Always cache the result, including if the exit status is on
8679 failure, since if nothing changes, we should result in the same
8680 failure, hence we can use the cache.
8681 * lib/m4sugar/m4sugar.m4 (m4_warning_ifelse, _m4_warning_ifelse)
8682 (_m4_warning_error_ifelse, __m4_warning_error_ifelse, _m4_warn):
8683 Remove.
8684 (m4_warn): Redefine as a do-nothing: it is its invocation that
8685 matters, as warnings are now reported via traces.
8686 * lib/autoconf/general.m4 (AC_DIAGNOSE): Don't make it a copy of
8687 the contents of m4_warn: make it _call_ m4_warn, so that tracing
8688 the latter reveals calls to the former.
8690 Adjust the tests.
8692 * tests/m4sugar.at (m4@&t@_warn): Use existing warning categories.
8694 2003-08-21 Akim Demaille <akim@epita.fr>

8706 (cross): New warning category.

8726 * bin/autom4te: Adjust.
8727 In particular, be Autoconf tools are really silent when properly
8728 working, bind the verbosity of the 'note' channel to $verbose.
8729 * lib/Autom4te/General.pm (&find_file, &mtime, &update_file)
8730 (&xsystem, &contents): Remove, since they are exported by...
8731 * lib/Autom4te/FileUtils.pm: this.
8732 More perldoc.
8733 * lib/Autom4te/General.pm (&up_to_date_p): Move to...
8734 * lib/Autom4te/FileUtils.pm: here.
8736 2003-08-20 Akim Demaille <akim@epita.fr>
8738 * lib/Autom4te/Channels.pm, lib/Autom4te/ChannelDefs.pm
8739 * lib/Autom4te/Configure_ac.pm, lib/Autom4te/FileUtils.pm: New,
8740 from CVS Automake.

8792 DESCRIPTION rather than FILE and LINE. Shorten result to fit in new,
8793 shorter column three. Add DESCRIPTION to log file content.
8795 2003-08-13 Derek Price <derek@ximbiot.com>
8797 * lib/autotest/general.m4 (AT_INIT): Correct typo in final status
8798 output.
8800 2003-08-12 Derek Price <derek@ximbiot.com>
8802 * lib/autotest/general.m4 (AT_CHECK): Use new _AT_CHECK API.
8803 (AT_CHECK_NOESCAPE): Move core functionality to...
8804 (_AT_CHECK): ...this new macro.
8806 2003-08-07 Derek Price <derek@ximbiot.com>
8808 * lib/autotest/general.m4 (AT_CHECK): Move core functionality...
8809 (AT_CHECK_NOESCAPE): ...to this new macro.
8811 2003-07-31 Paul Eggert <eggert@twinsun.com>
8813 * lib/m4sugar/m4sh.m4 (_AS_UNSET_PREPARE): Work around a bug
8814 in Bash 2.01. Problem reported by Brian Gough in
8815 <http://mail.gnu.org/archive/html/bug-autoconf/2003-07/msg00106.html>.
8817 2003-07-25 John W. Eaton <jwe@bevo.che.wisc.edu>
8819 * lib/autoconf/fortran.m4 (AC_F77_LIBRARY_LDFLAGS): Also ignore
8820 -lcrt1.o, for OS X. (trivial change)
8822 2003-07-07 Paul Eggert <eggert@twinsun.com>
8824 * lib/autoconf/c.m4 (AC_C_INLINE): Wrap the '#define inline ...'
8825 inside '#ifndef __cplusplus'. Problem reported by
8826 Bob Friesenhahn.
8828 2003-07-06 Bill Clarke <llib@computer.org>
8830 * lib/autoconf/functions.m4 (AC_FUNC_MMAP): Cast pointer to
8831 'long', not 'int', for benefit of Sun's recent C++ compilers
8832 (trivial change). See:
8833 http://mail.gnu.org/archive/html/autoconf-patches/2003-07/msg00007.html
8834 (This really should be 'intptr_t', not 'long', but that would
8835 take more work.)
8837 2003-06-25 Akim Demaille <akim@epita.fr>
8839 * lib/Makefile.am (autom4te.cfg): Make it read only.
8840 Depend on Makefile since it contains substitutions.
8841 From Paolo Bonzini.

8843 This change was made on autom4te.cfg which is generated.
8844 Reported by Raja R. Harinath.
8846 2003-06-25 Akim Demaille <akim@epita.fr>
8848 * doc/autoconf.texi (Header Portability): sys/mount.h.
8849 From Gareth McCaughan.
8851 2003-06-23 Akim Demaille <akim@epita.fr>
8853 * lib/autotest/general.m4 (AT_INIT): Report a single config.log,
8854 not all of them. This fixes 1. the fact that when testing
8855 Autoconf there are many many config.log, 2. the incorrect use of
8856 top_srcdir to find config.log.
8857 Don't mix the detailed output of failed test with the summary of
8858 failures. Rather, append detailed log afterwards.
8860 2003-06-23 Akim Demaille <akim@epita.fr>
8862 * tests/local.at (AT_CHECK_CONFIGURE): Adjust to the verbose being
8863 always run: output config.log on $at_group_log.
8865 2003-06-23 Akim Demaille <akim@epita.fr>
8867 * tests/torture.at (#define header templates): Don't use quotes in
8868 C++ comments as it puzzles Emacs' sh font-lock-mode.
8870 2003-06-23 Akim Demaille <akim@epita.fr>
8872 * tests/mktests.sh (au_exclude_egrep): Fix output copyright notice.
8873 * lib/autom4te.cfg (args): Add local.at? for Autotest args.
8874 * tests/atspecific.m4: Rename as...
8875 * tests/local.at: This.
8876 * tests/suite.at: Move the globals into...
8877 * tests/local.at: here.
8878 * tests/Makefile.am: Adjust.
8879 * doc/autoconf.texi (testsuite Scripts): Adjust.
8881 2003-06-21 Kevin Ryde <user42@zip.com.au>
8883 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Extend test program to get an
8884 error from OSF 4.0 Compaq cc in its default almost-ANSI mode, thereby
8885 ensuring we add -std1 for full-ANSI.
8887 * doc/autoconf.texi (hdrindex): New macro.
8888 Add index entries for portability of various standard header files.
8890 2003-06-20 Akim Demaille <akim@epita.fr>
8892 * configure.ac: Bump to 2.57b.
8894 2003-06-20 Akim Demaille <akim@epita.fr>
8896 Version 2.57a.
8898 2003-06-20 Akim Demaille <akim@epita.fr>
8900 * bin/autom4te.in: Don't rely on $HOME being defined.
8901 Reported by Marc Espie as PR/233.
8903 2003-06-20 Akim Demaille <akim@epita.fr>
8905 * lib/autotest/general.m4: Use at_times_file only if used.
8906 From Nicolas Joly.
8908 2003-06-20 Akim Demaille <akim@epita.fr>
8910 * config/config.guess, config/config.sub, config/elisp-comp,
8911 * config/install-sh, config/mkinstalldirs, doc/standards.texi:
8912 Update from masters.
8914 2003-06-11 Paolo Bonzini <bonzini@gnu.org>
8916 * doc/autoconf.texi (Writing testsuite.at): Document AT_XFAIL_IF
8917 * lib/autotest/general.m4 (AT_XFAIL_IF): New macro.
8918 (TEST_SCRIPT): New diversion.
8919 (AT_SETUP): Divert output to TEST_SCRIPT and move some code...
8920 (AT_CLEANUP): ...to here. Undivert TEST_SCRIPT.
8921 (AT_INIT): Support for expected failures.
8923 2003-06-02 Akim Demaille <akim@epita.fr>
8925 * bin/autom4te.in, bin/autoscan.in, bin/autoheader.in: White space
8926 changes.
8927 * lib/Autom4te/General.pm (&backname): Remove, no longer used by
8928 Autoconf nor Automake.
8929 (&contents): New, from Automake.
8930 PODify.
8932 2003-05-28 Paul Eggert <eggert@twinsun.com>
8934 * NEWS, doc/autoconf.texi (Particular Functions),
8935 lib/autoconf/functions.m4 (AC_FUNC_MKTIME): Check that mktime
8936 is the inverse of localtime.
8938 2003-05-25 Alexandre Duret-Lutz <adl@gnu.org>
8940 * lib/Autom4te/General.pm (END): Print diagnostics to STDERR.
8941 (handle_exec_errors): New function. Work around $! being
8942 altered by WEXITSTATUS.
8943 (xqx, xsystem): Use handle_exec_errors.
8945 2003-05-23 Alexandre Duret-Lutz <adl@gnu.org>
8947 * lib/Autom4te/General.pm (END): Rewrite exit code processing.
8948 Do not call `_exit()', simply modify `$?'.
8949 (xsystem): Reset $! before running system, and check it afterward.
8950 * tests/tools.at (autoupdating AC_PREREQ): Expect exit status
8951 63 for version mismatches.
8953 2003-05-23 Akim Demaille <akim@epita.fr>
8955 * lib/autoconf/status.m4: Prefer "TAB-SP" to "SP-TAB", because of
8956 Emacs' dangerous whitespace.el behavior (smashing "useless" spaces in
8957 the middle of a line).
8958 * lib/m4sugar/m4sugar.m4: Likewise.
8959 Remove useless spaces in comments.
8961 2003-05-23 Akim Demaille <akim@epita.fr>
8963 * lib/m4sugar/m4sugar.m4 (m4_version_prereq): Failure causes an
8964 exit 63, so that we (or Automake's "missing") can tell the
8965 difference with a plain failure.
8966 * doc/autoconf.texi (Notices): Adjust.
8968 2003-05-23 Akim Demaille <akim@epita.fr>
8970 * Makefile.am, bin/Makefile.am, config/Makefile.am,
8971 * doc/Makefile.am, lib/autoconf/Makefile.am, tests/Makefile.am:
8972 White spaces cleanup.
8974 2003-05-22 Jim Meyering <jim@meyering.net>
8975 Paul Eggert <eggert@twinsun.com>
8977 * lib/autoconf/c.m4 (_AC_PROG_CXX_EXIT_DECLARATION):
8978 Remove `#include <stdlib.h>' from the list; we should never
8979 make confdefs.h include <stdlib.h> or <cstdlib>, because the
8980 resulting namespace pollution would cause other tests to fail.
8981 Configure scripts run with some older versions of g++ and HP's
8982 aCC would fail due to such an #include. Problems reported by
8983 Matthew Mueller in <http://bugs.debian.org/120704> and by
8984 Keith Bostic in
8985 <http://mail.gnu.org/archive/html/autoconf/2003-05/msg00063.html>.
8986 In the test, use the test declaration before including <stdlib.h>,
8987 as that's closer to how it'll be used.
8989 2003-05-23 Akim Demaille <akim@epita.fr>
8991 * doc/autoconf.texi (Header Portability): ucred.h.
8992 From Ian Redfern.
8994 2003-05-22 Paolo Bonzini <bonzini@gnu.org>
8996 Overhaul Autotest's logging: generate separate log files
8997 in testsuite.dir/NNN/testsuite.log, and append them to
8998 testsuite.log instead of re-running the test verbosely.
9000 * lib/autotest/general.m4 (AT_INIT): Use a single redirected
9001 file descriptor, write 0 to at_status_file instead of setting
9002 at_status=0, initialize some new variables (at_status_file,
9003 at_group_log, at_suite_log, at_tee_pipe). Remove the cruft
9004 to rerun the tests, instead append the at_group_log to the
9005 at_suite_log when a test fails.
9006 (AT_SETUP): pipe the test case's output into at_tee_pipe,
9007 with the AS_MESSAGE_LOG_FD redirected to stdout.
9008 (AT_CLEANUP): save the output status in $at_status_file
9009 and restore it, redirect the AS_MESSAGE_LOG_FD back to
9010 its original place.
9011 (AT_CHECK): since tests are run with a redirected stdout,
9012 and used to be re-run in verbose mode, turn some $at_verbose
9013 into echo, and don't redirect the output of testing stdout
9014 and stderr.
9016 * lib/autotest/autoconf.texi (testsuite Scripts): Update
9017 the name of the debugging directory and information about
9018 its contents.
9020 2003-05-22 Paolo Bonzini <bonzini@gnu.org>
9022 * lib/m4sugar/m4sh.m4 (AS_REQUIRE): Actually use the 2nd
9023 parameter.
9025 2003-05-22 Akim Demaille <akim@epita.fr>
9027 * lib/autoconf/autotest.m4, lib/autoconf/autoupdate.m4
9028 * lib/autoconf/fortran.m4 lib/autoconf/general.m4
9029 * lib/autoconf/headers.m4 lib/autoconf/oldnames.m4

9046 Suggested by Jim Meyering.
9048 2003-05-22 Akim Demaille <akim@epita.fr>
9050 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Restore smashed
9051 ' \t' as '\t ' so that Emacs' whitespace.el keep it.
9052 Reported by Jim Meyering.
9054 2003-05-22 Akim Demaille <akim@epita.fr>
9056 * doc/autoconf.texi: Replace AC_HELP_STRING AS_HELP_STRING.

9058 Typos.
9059 Use '@.' for sentences that ended in a capital letter.
9060 From Art Haas.

9075 * bin/autoupdate.in ($m4): Fix quotation.
9076 Reported by Martin Mokrejs.
9078 2003-05-19 Paul Eggert <eggert@twinsun.com>
9080 * ChangeLog, ChangeLog.2, THANKS, lib/m4sugar/m4sugar.m4:

9087 AC_CHECK_HEADERS_NEW): New tests.
9089 2003-05-17 Akim Demaille <akim@epita.fr>
9091 * lib/autoconf/functions.m4: Use the default includes so that
9092 memcmp be declared before being tested.
9093 Reported by Sander Niemeijer.
9094 (AC_FUNC_ERROR_AT_LINE, AC_FUNC_GETGROUPS, AC_FUNC_STRNLEN): Likewise.
9095 * doc/autoconf.texi (Default Includes): Document
9096 AC_INCLUDES_DEFAULT.
9098 2003-05-17 Akim Demaille <akim@epita.fr>
9100 * lib/autoconf/specific.m4: Include signal.h and unistd.h.
9101 * doc/autoconf.texi (Obsolete Macros): Adjust.
9102 Reported by Werner LEMBERG and Debian Bug 190886.
9104 2003-05-16 Akim Demaille <akim@epita.fr>
9106 * lib/m4sugar/m4sh.m4 (_AS_UNSET_PREPARE): s/FOO/as_foo/ to avoid
9107 user name space clashes.
9108 Reported by Bruno Haible.
9110 2003-05-16 Akim Demaille <akim@epita.fr>
9112 * bin/autoheader.in, bin/autom4te.in, bin/autoreconf.in,
9113 * bin/autoscan.in, bin/autoupdate.in, bin/ifnames.in (BEGIN): Make
9114 them uniform, and more robust to Perl special characters.
9115 Reported by Martin Mokrejs.
9117 2003-05-14 Akim Demaille <akim@epita.fr>
9119 * tests/foreign.at (Libtool): Skip all Libtools pre 1.4.
9121 2003-05-14 Akim Demaille <akim@epita.fr>
9123 * doc/autoconf.texi (Header Portability): X11/extensions/scrnsaver.h,

9128 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Improve the
9129 message.
9130 From Matthias Andree.
9132 2003-05-07 Alexandre Duret-Lutz <adl@gnu.org>
9134 * lib/Autom4te/XFile.pm (lock, truncate): Do not pass @_ to flock
9135 and truncate.
9137 2003-05-06 Akim Demaille <akim@epita.fr>
9139 Don't try to be smart with aclocal 1.8+ because (i) aclocal no
9140 longer updates aclocal.m4 if useless, (ii) if a file m4_included
9141 by aclocal.m4 is changed it might require the importing of another
9142 m4 extension file, i.e., aclocal must be run.
9144 * bin/autoreconf.in (&run_aclocal, $aclocal_supports_force): New.
9145 (&parse_args): Use --force with aclocal if required and supported.
9146 (&autoreconf_current_directory): Use &run_aclocal.
9148 2003-05-06 Akim Demaille <akim@epita.fr>
9150 Lock autom4te's cache.
9152 * lib/Autom4te/XFile.pm ($me, &name, &lock, &truncate, &seek): New.
9153 * bin/autom4te.in (&Request::save, &Request::load): Use an IO::File
9154 argument instead of a file name, so that the request file remains
9155 open during the whole autom4te run.
9156 ($icache_file): New.
9157 (&freeze): Lock the $icache_file.
9159 2003-04-29 Derek Price <derek@ximbiot.com>
9161 * lib/autotest/general.m4 (AT_KEYWORDS): Don't use a comma as the
9162 seperator with m4_append_uniq(). It doesn't work.
9163 (AT_CLEANUP): Add `;' to end of at_help_all.
9164 (AT_INIT): Allow --keywords to be specified more than once. When
9165 grepping $at_help_all for keywords, use the field and keyword

9167 to support the new --keywords behavior.
9169 2003-04-27 Karl Berry <karl@freefriends.org>
9171 * doc/autoconf.texi: Make the dir entries in the autoconf manual
9172 align better with others. I also made some of the individual
9173 entries on one line, for brevity and to make it easier for me to

9320 (Automake): Automake 1.5+ no longer requires special tools to be
9321 present on the developer's host.

9330 * bin/autoreconf.in (BEGIN): Likewise.
9331 * bin/autoscan.in (BEGIN): Likewise.
9332 * bin/autoupdate.in (BEGIN): Likewise.

9337 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Translate colons,
9338 to cope with DOS-style absolute paths, when constructing
9339 ${ac_make}.
9341 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS, _AC_OUTPUT_FILES):
9342 When constructing paths with IFS=:, quote the path. If we're
9343 constructing a DOS-style absolute path, we don't want to split it
9344 on the colon.
9346 * tests/atspecific.m4 (AT_CHECK_CONFIGURE): Fix typo
9347 in description.
9349 2003-02-25 Pavel Roskin <proski@gnu.org>

9361 * doc/autoconf.texi (Shell Substitutions): test -n -> test -z,
9362 to fix a mismatch between example and discussion.

9366 * doc/autoconf.texi (Limitations of Builtins): Add notes on printf
9367 format starting with "-".
9369 2003-02-20 Alexandre Duret-Lutz <adl@gnu.org>
9371 * doc/autoconf.texi (Limitations of Make): `foo=bar make -e'
9372 is not portable inside Makefile.
9374 2003-02-20 Akim Demaille <akim@epita.fr>
9376 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): When
9377 compiler says yeah, but preproc says nope, compiler is right.
9378 Conversely, prompt the reader to send a bug report to the
9379 maintainers of the package, not of Autoconf.
9381 2003-02-20 Klee Dienes <kdienes@apple.com>
9383 * bin/autoreconf.in (autoreconf_current_directory): Properly

9389 $ac_prefix_program.
9390 From Larry Jones.
9392 2002-12-23 Paul Eggert <eggert@twinsun.com>
9394 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Define $1 to an
9395 innocuous variant befor including <limits.h> or <assert.h>. This
9396 works around a bug reported by Albert Chin: HP-UX 11i
9397 (and earlier versions) have a <limits.h> that declares
9398 gettimeofday and many other functions.
9400 2002-12-03 Paul Eggert <eggert@twinsun.com>
9402 Version 2.57.
9404 * NEWS, configure.ac: Update version.
9406 * doc/fdl.texi: Upgrade to FDL version 1.2.
9408 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Use the function f
9409 nontrivially in main's body, so that f's external declaration is
9410 not optimized away in AIX. This should fix the bug reported by
9411 Martin Frydl in
9412 <http://mail.gnu.org/pipermail/autoconf/2002-November/014508.html>.
9414 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C),
9415 _AC_PROG_PREPROC_WORKS_IFELSE): Use <limits.h> if __STDC__ is
9416 defined, to support freestanding compilers. This should fix the
9417 bug reported by Momchil Velkov in
9418 <http://mail.gnu.org/pipermail/autoconf/2002-November/014490.html>.
9420 * doc/autoconf.texi (Obsolete Macros): Fix typos (insert empty
9421 arg, AC_DEFINE -> AC_DEFINE_UNQUOTED) in documentation for

9426 * Makefile.maint (www-gnu): New macro.
9427 (standards.texi-url_prefix, make-stds.texi-url_prefix): Use it, as
9428 the location has moved.

9432 * bin/autom4te.in (at_flatten): rewritten to avoid M4 problem when
9433 \(.*\) match is too long and there is something more to be checked.
9434 <http://mail.gnu.org/pipermail/autoconf/2002-November/014524.html>
9436 2002-11-15 Akim Demaille <akim@epita.fr>

9443 * Makefile.am (AUTOMAKE_OPTIONS): Move to...
9444 * configure.ac (AM_INIT_AUTOMAKE): here.
9445 Require 1.7.1.
9447 2002-11-14 Akim Demaille <akim@epita.fr>
9449 Version 2.55.
9451 * config/config.guess, config/config.sub, config/install-sh:
9452 Update from masters.
9454 2002-11-14 Akim Demaille <akim@epita.fr>
9456 * Makefile.maint: Sync with Bison, i.e.:
9457 (po-check): Scan .l and .y files instead of the
9458 .c and the .h files that they generate. This fixes the bug
9459 reported by Tim Van Holder in:
9460 <http://mail.gnu.org/pipermail/bison-patches/2002-November/001352.html>
9461 Look for N_ as well as for _. Try to avoid matching #define for
9462 N_ and _.
9463 From Paul Eggert.
9465 2002-11-14 Akim Demaille <akim@epita.fr>
9467 * doc/autoconf.texi (C Compiler): Compiling several files at once.
9468 From Paul Eggert and Albert Chin-A-Young.
9470 2002-11-14 Akim Demaille <akim@epita.fr>

9473 From Paul Eggert and Albert Chin-A-Young.
9475 2002-11-14 Kevin Ryde <user42@zip.com.au>
9477 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Initialize f=$1 rather
9478 than assigning in main, to avoid HP cc +O3 optimizing it away.
9480 2002-11-12 Peter Eisentraut <peter_e@gmx.net>
9482 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Add -q
9483 option. Process --recheck after parsing all options. Pass -q
9484 option to configure on --recheck.
9485 (AC_OUTPUT): Pass -q from configure to config.status.
9486 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Strip -q from
9487 arguments to record.
9488 * doc/autoconf.texi (config.status Invocation): Document
9489 config.status -q option.
9491 2002-11-07 Alexandre Duret-Lutz <adl@gnu.org>
9493 * bin/autoscan.in (scan_file): Scan Makefile.am too. Ignore
9494 Makefile.in if Makefile.am exists.
9495 (output): Strip `.am' from Makefiles. Don't
9496 output AC_CONFIG_FILES if no Makefiles were found.
9498 2002-11-07 Akim Demaille <akim@epita.fr>
9500 * Makefile.am (cvs_files): Add elisp-comp, mdate-sh.

9505 2002-11-06 Akim Demaille <akim@epita.fr>
9507 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY): Wrap the `f'
9508 declaration in extern "C" too.

9513 * tests/torture.at (Configuring subdirectories): Don't use grep
9514 -w.
9515 * doc/autoconf.texi (Limitations of Usual Tools): Grep -w.
9516 Reported by Ezra Peisach.
9518 2002-11-05 Akim Demaille <akim@epita.fr>
9520 * lib/autoconf/autoheader.m4 (_AH_TEMPLATE_OLD, _AH_VERBATIM_OLD):
9521 Remove.
9522 We _have_ to stop using the old compatibility scheme that tried to
9523 avoid useless backslashes because Libtool 1.4.3 contains a
9524 AC_DEFINE([error_t], [int],
9525 [Define to a type to use for \`error_t' if it is not
9526 otherwise available.])
9527 We _have_ to quote the single quote and backslashes with \. The
9528 old compatibility scheme saw that ` was backslashed, and therefore
9529 did not quote the single quote. Hence before this patch, Autoconf
9530 was not compatible with Libtool.
9532 2002-11-04 Paul Eggert <eggert@twinsun.com>
9534 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Set the following variables,

9539 2002-11-04 Akim Demaille <akim@epita.fr>
9541 Version 2.54c.
9543 * Makefile.maint (update, cvs-update, po-update, do-po-update):
9544 New.
9545 * config/texinfo.tex: Update.
9547 2002-11-03 Akim Demaille <akim@epita.fr>
9549 * bin/autoreconf.in (&autoreconf_current_directory): New, extracted
9550 from...
9551 (&autoreconf): here.
9552 ($help, $make, &parse_args, &autoreconf_current_directory):
9553 Support -m/--make.
9554 * doc/autoconf.texi (autoreconf Invocation): Adjust.
9556 2002-10-31 Bruno Haible <bruno@clisp.org>

9569 * tests/atspecific.m4 (AC_STATE_SAVE): Don't use quadrigraphs here.
9570 (AT_CHECK_ENV): Make sure the `state-ls.before file exists.
9572 2002-10-31 Akim Demaille <akim@epita.fr>
9574 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Use and display
9575 `$(MAKE)' instead of '${MAKE}' to emphasize that we refer to the
9576 Make variable, not a shell variable.
9577 Suggested by Bruno Haible.
9579 2002-10-31 Akim Demaille <akim@epita.fr>
9581 * bin/autom4te.in (load_configuration): Reject #args out of any
9582 language.
9584 2002-10-31 Akim Demaille <akim@epita.fr>
9586 * lib/autoconf/general.m4 (_AC_MSG_LOG_CONFTEST): New.
9587 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE, _AC_LINK_IFELSE)
9588 (_AC_RUN_IFELSE): Use it.
9589 * lib/autoconf/lang.m4 (_AC_COMPILER_OBJEXT):
9590 (_AC_COMPILER_EXEEXT_DEFAULT): Likewise.
9591 * lib/autoconf/c.m4 (AC_LANG_SOURCE): Don't include confdefs.h,
9592 inline it.

9598 Suggested by Tim van Holder.
9600 2002-10-29 Paul Eggert <eggert@twinsun.com>
9602 * doc/autoconf.texi (Particular Functions): AC_FUNC_MALLOC and
9603 AC_FUNC_REALLOC check for compatibility with glibc, not POSIX.
9604 Problem reported by Bruno Haible.
9606 2002-10-29 Akim Demaille <akim@epita.fr>
9608 * doc/autoconf.texi (Header Templates): Put also in words what the
9609 pictures says to assist free style readers.
9610 (Customizing autom4te): s/--cache=/--cache /.
9612 2002-10-29 Akim Demaille <akim@epita.fr>
9614 * lib/autoconf/functions.m4 (_AC_FUNC_VFORK): Include stdlib.h and
9615 sys/wait.h.
9616 sparc_address_test returns void.
9617 Use it with an argument, as prototyped.
9618 From Bruno Haible.
9620 2002-10-29 Akim Demaille <akim@epita.fr>
9622 * doc/autoconf.texi (Subdirectories): Cygnus dirs have

9628 * tests/torture.at (Deep Package): New test.

9634 * bin/autoreconf.in (&parse_args, $help): Support --warnings.
9635 * doc/autoconf.texi (Invoking autom4te): Rename as...
9636 (autom4te Invocation): this, for consistency with the other nodes.
9638 2002-10-29 Akim Demaille <akim@epita.fr>
9640 * lib/autom4te.in (Autoconf): s/automate/autom4te/.
9641 Reported by Ralf Corsepius.
9643 2002-10-29 Akim Demaille <akim@epita.fr>
9645 * lib/m4sugar/m4sh.m4 (_AS_QUOTE): The warning about quoted
9646 characters is a back as an `obsolete' warning now.
9647 Reported by Ralf Corsepius.
9649 2002-10-28 Akim Demaille <akim@epita.fr>
9651 * configure.ac: Bump to 2.54c.
9653 2002-10-28 Akim Demaille <akim@epita.fr>
9655 Version 2.54b.

9862 2002-10-22 Akim Demaille <akim@epita.fr>
9864 * tests/foreign.at (Libtool): Don't check autoconf's stderr: there

9867 Quote for Perl '' strings, not "".
9868 * bin/autoheader.in: Invoke autoconf to get '' strings, not ""
9869 strings.
9871 2002-10-22 Akim Demaille <akim@epita.fr>
9873 * lib/m4sugar/m4sh.m4 (_AS_QUOTE): The warning about quoted

9919 Because of caching, some files that no longer exist and are no
9920 longer required can still cause errors.
9921 Reported by Alexandre Duret-Lutz.
9923 * bin/autom4te.in (&parse_args): Do not prepend `--reload-state'
9924 to frozen files in @ARGV, as @ARGV must remain being a list of
9925 files. Rather, at M4 call sites, use this...
9926 (&files_to_options): New function.
9927 (&freeze): Use &error.
9928 (&up_to_date): If a file that was included according to the cache
9929 is no longer there, then the output is out dated.
9930 (&main): Don't even check whether a file is up to date is anyway
9931 --force is given.
9932 * tests/tools.at (autom4te cache): New.
9934 2002-10-16 Akim Demaille <akim@epita.fr>
9936 * bin/autoconf.as: Kill dead options.
9937 * bin/autoupdate.in (&parse_args): Kill old options.
9938 * bin/autoreconf.in (&parse_args): Remove dead options.
9939 Factor some code.
9940 (&autoreconf): Report the directories we enter *and leave*, so
9941 that error messages can be easily located, and use GNU Make
9942 format, so that Emacs' compile mode understands us.
9943 * lib/Autom4te/General.pm (&update_file): Use `verbose' to report
9944 if some file was changed instead of `print'.
9945 * bin/autoheader.in: Suggest AC_DEFINE with 3 args when needed.
9946 (&parse_args): Remove the dead options.

9979 file name to enable parallel executions.
9980 From Sam Varshavchik.
9982 2002-10-08 Akim Demaille <akim@epita.fr>
9984 * bin/autoreconf.in (&autoreconf): Run autopoint before the first
9985 aclocal invocation, as Gettext macros might not be visible to
9986 aclocal.
9987 Instead of blindly running autopoint, scan configure.ac (not the
9988 traces) for AM_GNU_GETTEXT_VERSION uses, as autopoint does.
9989 Reported by Paul D. Smith.
9991 2002-10-08 Paul Eggert <eggert@twinsun.com>
9993 Work around problems found when POSIXLY_CORRECT=1 is set.
9994 None of this seems to have anything to do with POSIX, really,
9995 but it's how Perl getopt works.
9996 * bin/autom4te.in (parse_args): Configure GetOpt with
9997 "permute", too.
9998 * doc/autoconf.texi (Invoking autom4te):
9999 --warning -> --warnings.

10021 * tests/torture.at (Configuring subdirectories): Be robust to
10022 users who use config.site to require for a cache: in this case,
10023 the two last configure runs, using two different sets of
10024 arguments, trigger a legitimate error.
10026 2002-09-28 Akim Demaille <akim@epita.fr>
10028 * tests/m4sh.at (Functions Support, Functions and return Support):
10029 New.

10042 (tm_zone): Move their rules to...

10044 * lib/autoscan/autoscan.pre (AWK, BISON, INSTALL, LEX, LN, MAKE)
10045 (RANLIB, YACC, awk, bison, byacc, flex, gawk, install, lex, ln)

10059 * lib/freeze.mk (autoconf_m4f_dependencies): Add autoscan.m4.
10060 (.m4.m4f): Don't pass --prepend-include, since that's done by
10061 tests/autom4te itself.
10062 * lib/autoscan/Makefile.am: Include freeze.mk.
10063 (autoscan.list): New target --this file is no longer a source.
10064 (autoscan.pre): New file.
10066 2002-09-28 Akim Demaille <akim@epita.fr>
10068 * bin/autoscan.in (@kinds): Make them singular.
10069 Adjust all uses.
10070 (&init_tables): When --debug, report the list of rules to ease
10071 tracking changes in autoscan.list.
10072 * lib/autoscan/autoscan.list (function): Strip comments, sort.

10088 * bin/autoscan.in (&init_tables): Adjust.
10090 2002-09-28 Akim Demaille <akim@epita.fr>
10092 From now on, autoscan files must always map a macro name to a
10093 word: there is no `default' macro for autoscan.
10095 * bin/autoscan.in (&init_tables): Reject entries with no macro at
10096 all.
10097 * lib/autoscan/functions, lib/autoscan/headers: Make the macro
10098 explicit.
10100 2002-09-28 Akim Demaille <akim@epita.fr>

10146 (ifnames, autoscan, autom4te): Un-factor into several rules.
10148 2002-09-25 Paul Eggert <eggert@twinsun.com>
10150 * BUGS (Interoperability bugs): New section. Mention libtool
10151 1.4.2, configure.ac, and AC_CONFIG_AUX_DIR interoperability bug.
10153 2002-09-24 Paul Eggert <eggert@twinsun.com>
10155 Fix a portability bug reported by Alexandre Duret-Lutz: Solaris 8
10156 make handles suffix-rules differently from GNU make.
10158 * bin/Makefile.am (SUFFIXES, .in): Remove.
10159 (autoconf autoheader autoreconf autoupdate ifnames autoscan autom4te):
10160 Move the body of the old .in rule here.
10162 2002-09-16 Akim Demaille <akim@epita.fr>
10164 i960 compilers create `b.out' files by default.
10165 Reported by Ralf Corsepius.
10167 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT): Remove b.out files.
10168 (_AC_COMPILER_EXEEXT_DEFAULT): Adjust to b.out.
10170 2002-09-13 Paul Eggert <eggert@twinsun.com>
10172 * doc/autoconf.texi (Particular Headers): Remove obsolete
10173 reference to `struct timezone' in the description of
10174 AC_HEADER_TIME.
10176 2002-09-13 Akim Demaille <akim@epita.fr>
10178 Version 2.54.
10180 * config/config.sub, config/config.guess: Update.
10181 * Makefile.maint: Update from bits of the Coreutils 4.5.1.
10182 * Makefile.am: Adjust.
10184 2002-09-13 Akim Demaille <akim@epita.fr>
10186 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Suggest
10187 reading config.log when the compiler is rejected.
10188 Suggested by Guido Draheim.
10190 2002-09-13 Akim Demaille <akim@epita.fr>
10192 * bin/autoreconf.in: Don't use Cwd::chdir, since in its internals
10193 (chdir_init) might hang when stat'ing mounted directories.
10194 Reported by Vance Shipley.
10196 2002-09-12 Akim Demaille <akim@epita.fr>
10198 * bin/autoscan.in (&parse_args): Pass a reference to the lists, not
10199 the lists.
10201 2002-09-12 Akim Demaille <akim@epita.fr>
10203 * doc/autoconf.texi (Defining Symbols): Present two different
10204 prototypes for AC_DEFINE and AC_DEFINE_UNQUOTED to emphasize the
10205 difference between 1 argument calls, and 2-3 argument calls.
10207 2002-09-12 Peter Eisentraut <peter_e@gmx.net>
10209 * doc/autoconf.texi: Review grammar and punctuation.
10211 2002-09-11 Paul Eggert <eggert@twinsun.com>
10213 * doc/autoconf.texi: Fix minor formatting, spelling, and
10214 grammatical typos.
10215 (Defining Symbols): Explain that AC_DEFINE(var) defaults to 1, but
10216 AC_DEFINE(var,,description) does not; and the AC_DEFINE(var) case
10217 is obsolescent.
10219 2002-09-11 Akim Demaille <akim@epita.fr>
10221 * doc/autoconf.texi (Questions): Rename as...
10222 (FAQ): this.
10223 (Defining Directories): New.
10225 2002-09-09 Akim Demaille <akim@epita.fr>
10227 * doc/autoconf.texi (Making testsuite Scripts): Update.
10228 Suggested by Nishio Futoshi.
10230 2002-09-09 Koji Arai <JCA02266@nifty.ne.jp>
10232 * doc/autoconf.texi (Making testsuite Scripts): Use `@@' where a
10233 plain `@' is wanted.
10235 2002-09-09 Akim Demaille <akim@epita.fr>
10237 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Keep the
10238 `duplicates', since the algorithm was too naive and could keep
10239 `--prefix=1 --prefix=2 --prefix=1' as `--prefix=1 --prefix=2', and
10240 keep `--prefix foo --prefix bar' as `--prefix foo bar'.
10241 Reported by Ralf Corsepius.
10242 * tests/torture.at (Configuring subdirectories): Exercise these
10243 cases.
10245 2002-09-09 Akim Demaille <akim@epita.fr>
10247 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Use $srcdir when
10248 looking for a replacement file.
10249 * lib/autoconf/general.m4 (AC_CHECK_DECLS): Check that the
10250 directory is relative.
10251 * doc/autoconf.texi (Generic Functions): Clarify the replacement
10252 directory definition.
10253 Reported by Andreas Schwab and Jim Meyering.
10255 2002-09-06 Akim Demaille <akim@epita.fr>
10257 * doc/autoconf.texi (Setting Output Variables): Clarify what
10258 precious variables are.
10259 Suggested by Pontus Skoeld.
10261 2002-09-05 Akim Demaille <akim@epita.fr>
10263 * bin/Makefile.am (autoconf, autoheader, autoreconf, autoupdate)
10264 (ifnames, autoscan, autom4te): Since we don't only depend on
10265 configure.ac variables (such as VERSION etc.), but also on prefix
10266 and so forth, depend on Makefile, not configure.ac.
10267 Reported by Alexandre Duret-Lutz.
10268 * doc/autoconf.texi (Installation Directory Variables): Adjust.
10270 2002-09-05 Kevin Ryde <user42@zip.com.au>
10272 * doc/autoconf.texi (Limitations of Make): HP-UX trailing backslashes
10273 doesn't seem to be confined to ia64, just say "some versions".
10275 2002-09-04 Akim Demaille <akim@epita.fr>
10277 * Makefile.am, doc/Makefile.am: Remove pdf targets, handled by
10278 Automake 1.6c.
10279 * Makefile.am (maintainer-clean-local): Remove.
10280 (MAINTAINERCLEANFILES): Remove COPYING.
10282 2002-09-03 Paul Eggert <eggert@twinsun.com>
10284 * doc/autoconf.texi (Configuration Commands): Remove obsolete
10285 example for AC_CONFIG_COMMANDS_PRE. Problem reported by Marcus
10286 Brinkmann.
10288 2002-09-03 Akim Demaille <akim@epita.fr>
10290 * configure.ac: Bump to 2.53d.
10291 * Makefile.am (AUTOMAKE_OPTIONS): Require 1.6c, i.e., CVS Automake
10292 as of today, on Automake's team suggestion.
10294 2002-09-03 Akim Demaille <akim@epita.fr>
10296 Version 2.53c.
10298 2002-09-02 Akim Demaille <akim@epita.fr>
10300 * bin/autom4te.in (parse_args): Don't honor AUTOM4TE_PATH and
10301 SITE_MACRO_DIR.
10302 * configure.ac: Disable SITE_MACRO_DIR.
10304 2002-09-02 Jim Meyering <meyering@lucent.com>
10306 * doc/autoconf.texi (AC_SYS_POSIX_TERMIOS): Reflect renaming: s/am/ac/,
10307 i.e., change am_cv_sys_posix_termios to ac_cv_sys_posix_termios.
10308 Also, tweak grammar: s/make sure to/be sure to/.
10310 2002-09-02 Paul Eggert <eggert@twinsun.com>
10312 * doc/autoconf.texi (Limitations of Builtins): Explain why logical
10313 directory names are generally preferable to physical names.
10315 2002-09-02 Akim Demaille <akim@epita.fr>
10317 * lib/Autom4te/General.pm (&update_file): s/die/error/.
10318 Reported by Raja R. Harinath.
10319 * bin/autoheader.in, bin/autoreconf.in, bin/autoscan.in,
10320 * bin/autoupdate.in: Use error instead of die.
10322 2002-09-01 Paul Eggert <eggert@twinsun.com>
10324 * tests/mktests.sh (ac_exclude_egrep, au_exclude_egrep): Use
10325 ordinary shell concatenation rather than echo+tr+sed command that
10326 runs afoul of a long-line-related sed bug in Solaris 8.
10328 * bin/autoheader.in (parse_args): --warning -> --warnings.
10330 * bin/autoconf.as: Work even if "ls" outputs "FOO not found" to
10331 stdout, as traditional "ls" does.
10332 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT,
10333 _AC_COMPILER_EXEEXT_O): Likewise.
10334 * doc/autoconf.texi (Limitations of Usual Tools): Add "ls".
10336 * bin/autoconf.as: Add --prepend-include option. This patch was
10337 applied to bin/autoconf.in in the 2002-07-17 patch by Mark D. Roth,
10338 but bin/autoconf.in is generated automatically from bin/autoconf.as.
10340 * bin/autoconf.in, configure: Regenerate.
10342 * doc/autoconf.texi (Special Shell Variables): Mention
10343 ENV, MAIL, MAILPATH, PS1, PS2, PS4. Index PWD.
10345 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Unset ENV, MAIL,
10346 MAILPATH and set PS1, PS2, PS4 to default values, to work
10347 around bug in pre-3.0 UWIN ksh reported by Bruce Lilly.
10348 For LC_ALL etc, first try to set to "C" as POSIX requires and as
10349 the Autoconf documentation specifies; fall back to "unset" only if
10350 this fails. Use a shell for-loop for this rather than an m4 loop,
10351 to shorten the output script.
10353 2002-08-30 Paul Eggert <eggert@twinsun.com>
10355 * doc/autoconf.texi (Special Shell Variables): Mention POSIX
10356 1003.1-2001's requirements for CDPATH. Give a simpler workaround
10357 for the CDPATH problem. Document PWD.
10358 (Limitations of Builtins): Document the problem that "cd $foo" and
10359 "ls $foo" may refer to different directories in shells conforming
10360 to POSIX 1003.1-2001. Use PS1 rather than CDPATH for "unset"
10361 example, since the old example is now out of date.
10363 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Reject FOO if "cd
10364 FOO" and "ls FOO" talk about different directories; this catches
10365 problems when POSIX 1003.1-2001 "cd" fails due to symlink
10366 spaghetti.
10368 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Use AS_UNSET instead
10369 of rolling our own unset.
10370 (_AS_PREPARE): $as_unset CDPATH instead of AS_UNSETting it, since
10371 in practice we needn't worry about CDPATH if unset doesn't work.
10373 * Makefile.in, aclocal.m4, bin/Makefile.in,
10374 config/Makefile.in, doc/Makefile.in, lib/Makefile.in,
10375 lib/Autom4te/Makefile.in, lib/autoconf/Makefile.in,
10376 lib/autoscan/Makefile.in, lib/autotest/Makefile.in,
10377 lib/emacs/Makefile.in, lib/m4sugar/Makefile.in, man/Makefile.in,
10378 tests/Makefile.in: Regenerate with Automake 1.6.3.
10380 * config/config.guess, config/config.sub, config/mkinstalldirs:
10381 Update.
10383 * configure: Regenerate with self.
10385 2002-08-30 Kevin Ryde <user42@zip.com.au>
10387 * doc/autoconf.texi (Limitations of Usual Tools): Notes on "cc"
10388 default output.
10390 2002-08-29 Rainer Orth <ro@TechFak.Uni-Bielefeld.DE>
10392 * bin/autom4te.in (Request::load): Correctly test for "do" read
10393 failure.
10395 2002-08-29 Akim Demaille <akim@epita.fr>
10397 * lib/Autom4te/General.pm (&xqx): New.
10398 (&xsystem): Use WIFEXITED and WEXITSTATUS instead of decoding $? by
10399 hand, which is not portable.
10400 (&error): New.
10401 * bin/autom4te.in: Use them.
10402 Use &error instead of die.
10403 * tests/m4sugar.at (m4_warn, m4_require: circular dependencies):
10404 Adjust.
10406 2002-08-17 Paul Eggert <eggert@twinsun.com>
10408 * lib/autoconf/fortran.m4 (AC_PROG_F77): Remove fc from the
10409 default list of compilers to try, since it was long ago superseded
10410 by the ksh fc builtin. Suggested by Steven G. Johnson.
10412 2002-07-31 Alexandre Duret-Lutz <duret_g@epita.fr>
10414 * doc/autoconf.texi (Invoking autom4te): End the option table,
10415 fixing a bug introduced by the previous patch.
10416 (Limitations of Make): Add a 'target lookup' subentry in the
10417 'VPATH' entry. Rewrite all `make' occurences as `@command{make}'.
10419 2002-07-29 Mark D. Roth <roth@feep.net>
10421 * bin/autom4te.in: Remove --include-envvar and --site-macro-subdir
10422 options and use $AUTOM4TE_PATH.
10423 * doc/autoconf.texi: Remove documentation of autom4te
10424 --include-envvar and --site-macro-subdir options and document
10425 use of $AUTOM4TE_PATH.
10426 * lib/autom4te.in: Remove --include-envvar and --site-macro-subdir
10427 arguments from each language section.
10429 2002-07-29 Paul Eggert <eggert@twinsun.com>
10431 * doc/install.texi: Include copyright symbol in copyright notice.
10433 * Makefile.am (MAKEINFO): Remove; it's a user-specified macro.
10434 Replace with:
10435 (AM_MAKEINFOFLAGS): New macro.
10436 * doc/Makefile.am (MAKEINFO, AM_MAKEINFOFLAGS): Likewise.
10437 * Makefile.am (INSTALL): Use the new macros.
10438 Use -o rather than --output, since "missing" does not grok --output.
10440 2002-07-25 Alexandre Duret-Lutz <duret_g@epita.fr>
10442 * doc/autoconf.texi (Limitations of Make): Escaped newlines in
10443 comments do not always work. Never trust the exit status of
10444 `make -k'.
10446 2002-07-24 Kevin Ryde <user42@zip.com.au>
10448 * doc/autoconf.texi (Limitations of Make, Making testsuite Scripts):
10449 Untabify, since tabs are not enjoyed by texi2dvi and makeinfo.
10451 2002-07-23 Paul Eggert <eggert@twinsun.com>
10453 * lib/m4sugar/m4sh.m4 (_AS_PATH_SEPARATOR_PREPARE):
10454 Use PATH="/nonexistent;.", not PATH=".;.", as FreeBSD ksh2002
10455 apparently treats PATH="nonexistent" as if it contained ".".
10456 Bug reported by Stefan `Sec' Zehl.
10458 2002-07-22 Alexandre Duret-Lutz <duret_g@epita.fr>
10460 * doc/autoconf.texi (Limitations of Make): Mention the special
10461 handling of the obj/ directory by BSD make.
10463 2002-07-20 Kevin Ryde <user42@zip.com.au>

10473 2002-07-19 Akim Demaille <akim@epita.fr>
10475 * doc/autoconf.texi (AC_LIBOBJ vs LIBOBJS): More about $U.
10477 2002-07-18 Akim Demaille <akim@epita.fr>
10479 Version 2.53b.
10481 2002-07-18 Akim Demaille <akim@epita.fr>
10483 * config/config.guess, config/config.sub: Update.
10485 2002-07-18 Akim Demaille <akim@epita.fr>
10487 Handle LIBOBJS and LTLIBOBJS once for all, including Libtool's and
10488 Automake's parts.
10490 * lib/autoconf/general.m4 (_AC_LIBOBJS_NORMALIZE): New.
10491 * lib/autoconf/status.m4 (AC_OUTPUT_COMMANDS_PRE): Call it.
10492 * tests/semantics.at (AC_REPLACE_FUNCS): Adjust.
10494 2002-07-18 Akim Demaille <akim@epita.fr>,

10507 * lib/autoconf/functions.m4 (AC_FUNC_FORK): Don't set
10508 ac_cv_func_fork_works before running _AC_FUNC_FORK, do it if the
10509 latter was not run.
10511 2002-07-17 Akim Demaille <akim@epita.fr>
10513 * lib/Autom4te/General.pm (find_file): Browse the directories in
10514 the order they are given.

10534 macro directory, remove note that include path directories are
10535 used in reverse order, and document --prepend-include option.
10536 * lib/autom4te.in: Use --prepend-include instead of --include.
10537 * tests/wrapsh.in: Use --prepend-include instead of --include.
10539 2002-07-17 Akim Demaille <akim@epita.fr>

10580 so that Emacs setups GNU style for perl-mode and cperl-mode.
10582 2002-06-27 Paul Eggert <eggert@twinsun.com>
10584 * config/install-sh: Quote $src. Prefer || to test's -o option,
10585 as per "Limitations of Builtins".
10586 * tests/atspecific.m4 (AT_CHECK_ENV): Likewise, for && vs test -a.
10587 * tests/semantics.at (AC_C_BIGENDIAN): Likewise.
10589 * tests/mktests.sh: Use grep instead of fgrep, as per
10590 "Limitations of Builtins".

10594 * tests/wrapsh.as (AUTOCONF, AUTOHEADER, AUTOM4TE, AUTOM4TE_CFG,
10595 autom4te_perllibdir): Set to top build dir or src dir as appropriate,
10596 so that we consistently test the just-built programs.
10597 * tests/wrappl.as: Likewise.
10599 2002-06-12 Paul Eggert <eggert@twinsun.com>
10601 * bin/autoconf.as (AUTOM4TE): Default to a fully qualified path
10602 name, so that symlinks to 'autoconf' work properly. Bug reported
10603 by Bruno Haible.
10604 * bin/autoheader.in (AUTOM4TE): Likewise.
10605 * bin/autoreconf.in (autoconf, autoheader): Likewise.
10606 * bin/autoscan.in (autom4te): Likewise.
10607 * bin/autoupdate.in (autom4te): Likewise.
10609 * lib/autoconf/functions.m4 (_AC_LIBOBJ_FNMATCH): Also check for
10610 btowc, to fix a portability bug with diffutils-2.8.2/lib/fnmatch.c
10611 on Solaris 2.5.1.
10613 2002-06-11 Andreas Schwab <schwab@suse.de>
10615 * doc/autoconf.texi: Add more dir entries.
10617 2002-06-10 Alexandre Duret-Lutz <duret_g@epita.fr>
10619 * bin/autom4te.in ($cache): Don't define using `$me', the name

10638 (AC_REPLACE_FNMATCH): this.
10639 * tests/mktests.sh (exclude_list): Exclude AC_REPLACE_FNMATCH,
10640 AC_FUNC_FNMATCH_GNU.
10642 2002-06-07 Akim Demaille <akim@epita.fr>
10644 * doc/autoconf.texi (Systemology): Point to Tru64 docs, and the
10645 Rosetta Stone for Unix.
10647 2002-06-07 Akim Demaille <akim@epita.fr>
10649 * bin/autom4te.in (warn_forbidden): When rejecting a token,
10650 suggest m4_pattern_allow.
10651 Suggested by Adam J. Richter.
10653 2002-06-07 Akim Demaille <akim@epita.fr>
10655 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Initialize
10656 ac_config_libobj_dir.
10657 (AC_CONFIG_LIBOBJ_DIR): New.
10658 * lib/autoconf/functions.m4 (_AC_FUNC_FNMATCH): Split into...
10659 (_AC_FUNC_FNMATCH_IF, _AC_LIBOBJ_FNMATCH): these.
10660 Use ac_config_libobj_dir to find the replacement files.
10661 (AC_FUNC_FNMATCH, AC_FUNC_FNMATCH_GNU): Split into...
10662 (AC_FUNC_FNMATCH, AC_FUNC_FNMATCH_GNU, AC_REPLACE_FNMATCH)
10663 (AC_REPLACE_FNMATCH_GNU): these.
10664 (AC_FUNC_GETLOADAVG): Use ac_config_libobj_dir.
10665 * doc/autoconf.texi (Particular Functions, Generic Functions): Adjust.
10666 * tests/mktests.sh (ac_exclude_list): Don't check
10667 AC_FUNC_GETLOADAVG as it requires getloadavg.c which is not shipped.
10669 2002-06-06 Paul Eggert <eggert@twinsun.com>
10671 * lib/autoconf/status.m4 (_AC_OUTPUT_LINKS): Fall back on cp
10672 if ln doesn't work.
10673 * NEWS: Likewise.
10674 * doc/autoconf.texi (Configuration Links): Likewise.

10677 2002-06-05 Paul Eggert <eggert@twinsun.com>
10679 * config/config.guess, config/config.sub, config/texinfo.tex:
10680 Update from masters.
10682 2002-05-29 Paul Eggert <eggert@twinsun.com>

10716 * lib/autoconf/fortran.m4 (AC_PROG_F77): Remove cf77 and cft77
10717 from the default list of compilers to try. Suggested by
10718 Kate Hedstrom.
10719 * NEWS: Document the above.
10720 * doc/autoconf.texi (Fortran 77 Compiler): Don't suggest cf77.
10722 2002-05-17 Paul Eggert <eggert@twinsun.com>
10724 * lib/autoconf/types.m4 (AC_CHECK_MEMBER): Work correctly even if
10725 the member is itself an aggregate. Bug reported by Sergey Poznyakoff.
10726 This improves on an earlier suggestion by H. Peter Anvin.
10728 2002-05-16 Paul Eggert <eggert@twinsun.com>
10730 AC_FUNC_FNMATCH now tests only for POSIX compatibility.
10731 AC_FUNC_FNMATCH_GNU also tests for GNU extensions.
10732 Both macros now accept an optional source-dir arg.
10733 New macro AC_GNU_SOURCE to define _GNU_SOURCE.
10735 * NEWS: Document this.
10736 * doc/autoconf.texi (Particular Functions, UNIX Variants): Likewise.
10738 * lib/autoconf/functions.m4 (_AC_FUNC_FNMATCH): New macro.
10739 (AC_FUNC_FNMATCH): Use it. Test only for POSIX conformance,
10740 not for GNU extensions; this undoes part of the 2000-11-03 change,
10741 reverting to 2.13-compatible behavior.
10742 Add new optional argument DIR.
10743 (AC_FUNC_FNMATCH_GNU): New macro.
10745 * lib/autoconf/specific.m4 (AC_GNU_SOURCE): New macro.
10747 2002-05-08 Paul Eggert <eggert@twinsun.com>
10749 * lib/autoconf/headers.m4 (AC_HEADER_TIOCGWINSZ):
10750 Don't require AC_SYS_POSIX_TERMIOS. The test is unnecessary,
10751 and it causes a 'test' syntax error if it fails.
10752 Bug reported by Stephen Gildea.
10754 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
10755 If prototypes are supported, use them to check this at compile-time,
10756 instead of trying to check it at run-time. If we must do a run-time
10757 check, assume that setvbuf is standard when cross-compiling, as
10758 nonstandard setvbuf occurs only on ancient and unlikely hosts.
10759 Bug reported by Paul D. Smith.
10761 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Add optional
10762 argument specifying location of getloadavg.c. This removes a
10763 FIXME. This idea was taken from Jim Meyering's implementation in
10764 textutils.
10765 * doc/autoconf.texi (Particular Functions): Document this.
10766 Also, mention HAVE_NLIST_H rather than NLIST_STRUCT, since
10767 that's what the code does; this fixes a bug reported by
10768 Paul D. Smith.
10770 2002-05-03 Akim Demaille <akim@epita.fr>
10772 * bin/autoreconf.in (autoreconf): Rewrite to use Gettext's
10773 autopoint instead of gettextize.
10774 ($uses_alocal): Rename as...
10775 ($uses_aclocal): this.
10776 * doc/autoconf.texi (autoreconf Invocation): Adjust.
10777 Suggested by Bruno Haible.
10779 2002-05-03 Akim Demaille <akim@epita.fr>
10781 * lib/m4sugar/m4sugar.m4 (m4_map_sep): New.
10783 2002-04-29 Paul Eggert <eggert@twinsun.com>
10785 * bin/autoreconf.in (autoreconf): Don't age aclocal.m4's input
10786 files to be 1 second older; just set them to be the same time.
10787 Also, sleep 1 second after the first aclocal, to work around
10788 problems with sub-second time stamps on the input files.
10790 2002-04-29 Thien-Thi Nguyen <ttn@gnu.org>
10792 * doc/autoconf.texi: Mention "set -e -x" lossage
10793 under node "Limitations of Builtins".
10795 2002-04-29 Akim Demaille <akim@epita.fr>
10797 * doc/install.texi: Better wording for setting variables when
10798 running configure.
10799 From Christian Cornelssen.
10801 2002-04-29 Akim Demaille <akim@epita.fr>
10803 * tests/m4sh.at (LINENO): If testsuite itself is rewritten because
10804 of lack of $LINENO support, then the test will compare the $LINENO
10805 in testsuite vs. the lineno in the test file. This is wrong, of
10806 course.
10807 Be sure to protect it.
10808 Reported by Patrick Welche.
10810 2002-04-25 Akim Demaille <akim@epita.fr>
10812 * doc/autoconf.texi (Obsolete Macros): Typo.
10813 Reported by Vladimir Volovich.
10815 2002-04-25 Akim Demaille <akim@epita.fr>
10817 * bin/autoreconf.in (autoreconf): Don't let aclocal.m4 be older
10818 than some of the input files, hence, on the second run of aclocal,
10819 if some of its input are younger, make them older.
10820 Suggested by Paul Eggert.
10822 2002-04-25 Akim Demaille <akim@epita.fr>
10824 * doc/autoconf.texi (Limitations of Usual Tools): sed and `!'.
10825 Thanks to Paul Eggert.
10827 2002-04-25 Akim Demaille <akim@epita.fr>
10829 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Let ac_subst_files
10830 and ac_subst_vars be sh variables containing the list of
10831 AC_SUBST_FILES'ed and AC_SUBST'ed identifiers. Output them in the
10832 DEFAULT diversion.
10833 (_AC_INIT_PREPARE): Use them to log them.
10834 (_AC_SUBST, _AC_SUBST_SED_PROGRAM): Remove.
10835 (AC_SUBST, AC_SUBST_FILE): Instead of buliding the
10836 _AC_SUBST_SED_PROGRAM, store the list of output files/variables in
10837 _AC_SUBST_FILES and _AC_SUBST_VARS.
10838 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Adjust.
10840 2002-04-24 Akim Demaille <akim@epita.fr>
10842 * bin/autoreconf.in (autoreconf): Run automake after autoconf and
10843 autoheader, so that automake does not complain about a missing
10844 config.h.in that was to be created.
10846 2002-04-23 Akim Demaille <akim@epita.fr>
10848 * bin/autoheader.in (parse_args): --warning takes an argument.
10849 Fixes PR/220.
10851 2002-04-22 Peter Eisentraut <peter_e@gmx.net>
10853 * lib/autoconf/general.m4 (_AC_RUN_IFELSE): Remove gmon.out

10868 Reported by Gregory Giannoni.
10870 2002-04-22 Akim Demaille <akim@epita.fr>
10872 * tests/m4sh.at (LINENO): Skip the test if LINENO cannot be unset.
10873 Fixes false failures on Darwin.

10898 Minor spelling and grammar fixes.
10900 * doc/autoconf.texi: Follow the outline suggested in the GNU
10901 Sample Texts sections of the Texinfo 4.2 manual. Most
10902 importantly, this makes sure that the copyright notices appear in
10903 all output formats. You probably need Texinfo 4.2 to generate
10904 the manual now.
10906 Fix some bugs when using "$@" when there might be zero positional
10907 arguments in cases where this matters.

10932 * bin/autoupdate.in (handle_autoconf_macros): Honor AU_DEFUNs

10953 * tests/m4sh.at (AT_DATA_LINENO): Use _AS_PREPARE.
10955 Adjust Autoconf and Autotest.
10957 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Don't invoke
10958 AS_SHELL_SANITIZE, AS_INIT did it, but invoke AS_PREPARE.
10959 * lib/autotest/general.m4 (AT_INIT): Likewise.
10960 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):

11005 Extracted from...

11007 (AC_CONFIG_LINKS): here.
11008 Adjust.
11009 Don't use the KILL diversion, as it kills spurious output, which
11010 results in failures being hidden.
11011 Use m4_defn where appropriate.
11012 (AC_CONFIG_IF_MEMBER): Kill the real bug: a spurious parenthesis
11013 after the second argument.
11014 Use m4_defn.
11015 * lib/autom4te.in (Autoconf, Autotest, M4sh): Don't pass --warning

11087 2002-03-21 Paul Eggert <eggert@twinsun.com>
11089 * doc/autoconf.texi (Here-Documents): Mention Solaris 8 dtksh
11090 problem with here-document buffer boundaries.
11092 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Unset ENV and BASH_ENV
11093 when reinvoking the shell, to work around problems with installers
11094 who put strange things like "cd" commands in their environments.
11096 2002-03-19 Akim Demaille <akim@epita.fr>
11098 * tests/semantics.at (AC_C_BIGENDIAN): s/unknow/unknown/.
11099 From Aaron Ucko.
11101 2002-03-19 Akim Demaille <akim@epita.fr>
11103 * bin/autoscan.in (scan_file): Specify the location in `&used'
11104 invocations.
11105 From Nicolas Joly.
11107 2002-03-19 Akim Demaille <akim@epita.fr>
11109 * doc/autoconf.texi: Adjust @code/@command, @xref/@ref usage.
11110 From Nishio Futoshi.
11112 2002-03-19 Akim Demaille <akim@epita.fr>
11114 * lib/m4sugar/m4sugar.m4 (m4_define_default, m4_fst, m4_map): New.
11116 2002-03-18 Paul Eggert <eggert@twinsun.com>
11118 * doc/autoconf.texi (Programming in M4sh): Add AS_MKDIR_P.
11119 (Limitations of Usual Tools): Add mkdir section.
11121 * lib/m4sugar/m4sh.m4 (_AS_MKDIR_P_PREPARE): New macro.
11122 (AS_MKDIR_P): Require it. Use mkdir -p if available, falling
11123 back on AS_DIRNAME to compute prefixes otherwise; this is
11124 roughly what mkinstalldirs does. That way, we need not have
11125 our own filename disassembler. The old disassembler did not
11126 work with Solaris 8 dtksh, which is ksh Version M-12/28/93d.
11128 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP):
11129 Create at_test_all by a series of assignments,
11130 not by a single assignment of a long string. The latter causes ksh
11131 version 11/16/88g to silently misbehave on OpenServer 5.0.6a,
11132 presumably because of a buffer overrun.
11134 2002-03-14 Paul Eggert <eggert@twinsun.com>
11136 * lib/autotest/general.m4 (at_times_skip):
11137 Renamed from at_times. Now a boolean.
11138 ksh93 Version M-12/28/93d doesn't like 'x=times; $x'; it
11139 says 'times: not found'.
11141 2002-03-14 Akim Demaille <akim@epita.fr>
11143 * bin/autoreconf.in (&study_gettextize): New.
11144 (&autoreconf): Handle newest gettextize.
11145 Rerun aclocal if needed.
11146 Suggested by Andreas Schwab.
11148 2002-03-13 Akim Demaille <akim@epita.fr>
11150 * doc/autoconf.texi (Special Shell Variables): More about IFS.
11152 2002-03-13 Akim Demaille <akim@epita.fr>
11154 * doc/autoconf.texi (Header Portability): New.
11155 Add information about stdint.h and inttypes.h from Paul Eggert.
11157 2002-03-13 Akim Demaille <akim@epita.fr>
11159 * doc/autoconf.texi (Limitations of Usual Tools): Some about `cp
11160 -p'.
11161 From Bob Proulx.
11163 2002-03-12 Akim Demaille <akim@epita.fr>
11165 * lib/m4sugar/m4sh.m4 (AS_BASENAME_EXPR): AS_REQUIRE, not
11166 m4_require.
11168 2002-03-11 Andreas Schwab <schwab@suse.de>
11170 * configure.ac: Explicitly check for EMACS since AM_PATH_LISPDIR
11171 does not do it if --with-lispdir is given.
11173 2002-03-08 Akim Demaille <akim@epita.fr>
11175 Version 2.53.
11177 2002-03-08 Akim Demaille <akim@epita.fr>
11179 * doc/autoconf.texi (Subdirectories): Clarify that the
11180 subdirectory should exist.
11182 2002-03-08 Akim Demaille <akim@epita.fr>
11184 * Makefile.am (AUTOMAKE_OPTIONS): 1.6.
11186 2002-03-08 Akim Demaille <akim@epita.fr>
11188 * bin/autom4te.in (&handle_m4): Do not foreach with `$_' as it
11189 aliases the actual variables, and modifications of the former
11190 affect the latter.
11192 2002-03-08 Akim Demaille <akim@epita.fr>
11194 * bin/autom4te.in (&handle_m4): Protect us from corrupted file
11195 because of C-c: have m4 output in tmp files, then mv them.
11197 2002-03-08 Akim Demaille <akim@epita.fr>
11199 * bin/autoconf.in, bin/autoheader.in, bin/autom4te.in,
11200 * bin/autoreconf.in, bin/autoscan.in, bin/autoupdate.in,

11205 * doc/autoconf.texi (Invoking autom4te): New.
11207 2002-03-05 Akim Demaille <akim@epita.fr>
11209 * doc/autoconf.texi (Specifying Names): Clarification suggested by
11210 Kevin Ryde.
11212 2002-03-05 Akim Demaille <akim@epita.fr>
11214 Version 2.52i.
11216 2002-03-04 Akim Demaille <akim@epita.fr>
11218 * doc/autoconf.texi (AC_LIBOBJ vs. LIBOBJS): New.
11219 * lib/autoconf/general.m4 (AC_INIT): More informative error
11220 message for LIBOBJ.
11222 2002-03-04 Akim Demaille <akim@epita.fr>
11224 * lib/freeze.mk ($(build_libdir)/m4sugar/version.m4): New, for
11225 parallel builds.
11227 2002-03-04 Akim Demaille <akim@epita.fr>
11229 * doc/autoconf.texi (Transforming Names): Equality between target
11230 and host is irrelevant.
11231 (Specifying Names, Canonicalizing): Remove all references to the
11232 backward compatibility hooks. Rather, collect them all into...
11233 (Hosts and Cross-Compilation): this new section.
11234 * doc/install.texi (System Type): Ditto.
11235 * lib/autoconf/general.m4 (AC_CANONICAL_HOST): Explicitly state
11236 that `--host' implies cross-compilation.
11238 2002-03-04 Akim Demaille <akim@epita.fr>
11240 * doc/autoconf.texi (Evaluation Macros): New.
11241 * lib/m4sugar/m4sugar.m4 (m4_lquote): Remove, it is totally
11242 useless.
11243 (_m4_foreach): Define the variant with immediate evaluation so
11244 that it contains exactly the items, not an expression which
11245 evaluation is the current item.
11246 (m4_re_string, m4_re_word): Don't over quote them.
11248 2002-03-04 Akim Demaille <akim@epita.fr>
11250 Instead of having stacking `shift's evaluated at the end, let
11251 `foreach' loops immediately evaluate them.
11253 * lib/m4sugar/m4sugar.m4 (m4_quote, m4_dquote): Use $@ rather than
11254 $*. This is the n-th time I change my mind, but hopefully this is
11255 the last...
11256 (m4_lquote): New.
11257 (m4_text_wrap): Use m4_foreach, which is finally correct _and_
11258 efficient.
11259 (m4_foreach_quoted, m4_car_quoted, _m4_foreach_quoted): Remove, as
11260 it was only a hack for m4_text_wrap.
11261 (m4_car2): Remove, replaced by...
11262 (m4_cdr): New.
11263 (_m4_foreach): Adjust.
11264 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Adjust, and use
11265 m4_bpatsubst for clarification.
11267 2002-03-04 Akim Demaille <akim@epita.fr>
11269 * doc/autoconf.texi (Changequote is Evil): New.
11271 2002-03-03 Kevin Ryde <user42@zip.com.au>
11273 * doc/autoconf.texi (Portable Shell): Mention 32-byte #! length limit
11274 on old systems like SunOS.

11296 From Akinori Musha.
11298 2002-02-13 Alexandre Duret-Lutz <duret_g@epita.fr>
11300 * lib/Autom4te/XFile.pm (getline, getlines): New functions,
11301 translate \r\n to \n.
11303 2002-02-07 Akim Demaille <akim@epita.fr>
11305 Version 2.52h.
11307 2002-02-07 Akim Demaille <akim@epita.fr>
11309 Fix Autoconf PR/209.
11310 Also reported by Frank Denis.
11312 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Don't over quote.
11314 2002-02-07 Akim Demaille <akim@epita.fr>
11316 Fix Autoconf PR/207:
11317 AC_PREFIX_PROGRAM fails with dashed program names
11319 * lib/autoconf/general.m4 (AC_PREFIX_PROGRAM): Just use a fresh
11320 variable when looking for the prefix program.
11321 Now it also works for shell variables.
11323 2002-02-07 Akim Demaille <akim@epita.fr>

11330 * lib/autoconf/status.m4 (_AC_OUTPUT_COMMANDS): Don't output empty
11331 case/esac, some shells don't support it.
11332 Reported by Zack Weinberg.

11335 2002-02-06 Akim Demaille <akim@epita.fr>
11337 * lib/autotest/general.m4 (AT_INIT): When handling --keywords, be
11338 sure not to introduce newlines in at_groups.
11339 * lib/autotest/Makefile.am (autotest.m4f): Typo.
11341 2002-02-06 Akim Demaille <akim@epita.fr>
11343 * tests/torture.at (Configuring subdirectories): Skip if aclocal
11344 is not available.
11346 2002-02-05 Paul Eggert <eggert@twinsun.com>
11348 * doc/autoconf.texi (Specific Compiler Characteristics):
11349 Describe HP-UX cc bug workaround more accurately.
11350 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Cast to long,
11351 not unsigned long.
11352 * tests/semantics.at (AC_CHECK_SIZEOF): Check non-GCC
11353 cross-compilers, too. This undoes some of the most recent change
11354 to this file.
11356 2002-02-05 Akim Demaille <akim@epita.fr>
11358 * tests/Makefile.am (check_SCRIPTS): Use it, instead of WRAPPERS,
11359 to make sure they are up to date when `check' is run.

11363 * doc/autoconf.texi (Making testsuite Scripts): Document

11368 * lib/freeze.mk: New.
11370 2002-02-05 Akim Demaille <akim@epita.fr>
11372 Implement `autom4te --freeze'.
11374 * bin/autom4te.in (&freeze): New.
11375 * lib/autoconf/autoconf.m4, lib/autotest/general.m4,
11376 * lib/m4sugar/m4sh.m4: Don't include files given by autom4te.
11378 2002-02-05 Akim Demaille <akim@epita.fr>
11380 * bin/autom4te.in (&parse_args): Implement `frozen files are
11381 optional are the sum of the previous files on the command line'.
11382 Also, pass `--reload-state=' on them, so...
11383 (handle_m4): don't.
11384 * lib/autom4te.in (Autotest, Autoconf): Rely on M4sh.
11385 (M4sh): Rely on M4sugar.
11386 (Autotest, M4sh, M4sugar): Use frozen files.
11388 2002-01-31 Akim Demaille <akim@epita.fr>
11390 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Accept $4.
11391 * doc/autoconf.texi (Initializing configure): Adjust.
11393 2002-01-30 Akim Demaille <akim@epita.fr>
11395 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Map non
11396 alphanumeric to `-' instead of `_'.
11398 2002-01-30 Akim Demaille <akim@epita.fr>
11400 * tests/semantics.at (AC_CHECK_SIZEOF): Split into two tests: one
11401 for plain code, the other for cross-compilation code. The latter
11402 is now run with GCC only.
11403 * doc/autoconf.texi (Compilers and Preprocessors): New.
11405 2002-01-30 Akim Demaille <akim@epita.fr>
11407 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Support pre-defined
11408 values.
11409 * doc/autoconf.texi (Initializing configure): Explain how to
11410 change AC_INIT default values.
11412 2002-01-29 Akim Demaille <akim@epita.fr>
11414 * tests/torture.at (Configuring subdirectories): Use configure.in,
11415 so that aclocal 1.4 works.
11416 Reported by Alexandre Duret-Lutz and Larry Schmitt.
11418 2002-01-28 Akim Demaille <akim@epita.fr>
11420 * doc/autoconf.texi (Writing testsuite.at): AT_CLEANUP no longer
11421 needs an argument.
11423 2002-01-28 Akim Demaille <akim@epita.fr>
11425 * lib/autotest/general.m4 (AT_INIT): Don't be ridiculous: adjust
11426 AUTOTEST_PATH *after* it was set.
11427 Don't put `.' in the PATH: the user should be precise and `./' if
11428 needed. In addition, given that the test suite does some `cd', if
11429 `.' is in the path, the `tested programs' sections will report
11430 programs found in the test suite's directory, while during the
11431 tests (performed in their own directory), these programs are no
11432 longer visible. In other words, the results is confusing and
11433 useless.
11434 * tests/m4sh.at: Adjust: don't rely on `.' being in the PATH.
11436 2002-01-24 Akim Demaille <akim@epita.fr>

11464 Automake.
11466 2002-01-24 Akim Demaille <akim@epita.fr>
11468 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS)

11472 2002-01-21 Akim Demaille <akim@epita.fr>

11476 2002-01-21 Akim Demaille <akim@epita.fr>
11478 * lib/Autom4te/General.pm (getopt): Use a more GNUish error
11479 message on invalid options.
11480 * bin/autom4te.in (parse_args): Don't use
11481 Autoconf::General::getopt with non valid options.
11483 2002-01-17 Jim Meyering <meyering@lucent.com>
11485 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Initialize
11486 $ac_cv_exeext so we don't use an old, invalid, cached value.
11488 2002-01-11 Akim Demaille <akim@epita.fr>
11490 * lib/autoconf/functions.m4 (AC_FUNC_STRNLEN): New, from Jim
11491 Meyering.

11493 limitation.

11497 2002-01-06 Akim Demaille <akim@epita.fr>
11499 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Don't create
11500 package.m4, since is really depends upon configure.ac, not
11501 configure.
11502 * doc/autoconf.texi (testsuite Scripts): Adjust.
11503 * tests/Makefile.am (package.m4): New.
11504 EXTRA_DIST it since its a source.
11506 2002-01-06 Akim Demaille <akim@epita.fr>
11508 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Move the AC_SUBST
11509 of PACKAGE_NAME, PACKAGE_TARNAME, PACKAGE_VERSION, PACKAGE_STRING,
11510 and PACKAGE_BUGREPORT from here...
11511 (_AC_INIT_DEFAULTS): to here, since it is unrelated to the
11512 arguments.
11513 (_AC_INIT_PREPARE): AC_DEFINE these symbols.
11514 * lib/autotest/general.m4: Use AT_PACKAGE_*, not PACKAGE_*.
11515 (AT_INIT): No longer catch `^PACKAGE_(BUGREPORT|STRING)$'.
11516 * tests/tools.at (autoheader): Adjust.
11517 * tests/atspecific.m4 (AT_CHECK_DEFINES): Adjust.

11538 2001-12-14 Akim Demaille <akim@epita.fr>
11540 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): We cleaning up the
11541 trailing files, don't apply `-rf' to files which might not be
11542 created by configure (core, core.*, and *.core), but just `rm -f'.
11543 Suggested by Jonathan Kamens.
11545 2001-12-14 Aaron M. Ucko <amu@alum.mit.edu>
11547 * lib/autoconf/general.m4: Avoid duplicates in `$ac_configure_args'.

11577 Map to 1 in order to simplify its uses.
11579 2001-11-26 Akim Demaille <akim@epita.fr>
11581 * bin/autoscan.in (&scan_c_file, &scan_sh_file, &scan_makefile):
11582 Remove $filepath, useless.
11583 (&scan_makefile): Don't remove the $(FOO), ${FOO} and @FOO@
11584 variables, they are really part of the tokens.
11585 Split the input line on spaces and then look for tokens.
11586 Now autoscan ceases to ask for AC_PROG_LEX for the package Bison
11587 because of `lex$U.$(OBJEXT)'.
11588 (&scan_files): Use "@list" instead of join.
11589 * doc/Makefile.am (CLEANFILES): Add *.fns.
11591 2001-11-26 Akim Demaille <akim@epita.fr>
11593 * tests/autoreconf.in, tests/autom4te.in, tests/autoupdate.in:
11594 Remove, replaced by...
11595 * tests/wrappl.in: Be common for all the Perl executables.
11596 In particular autoscan and autoheader want -I.
11597 * configure.ac: Adjust.
11598 * lib/autoscan/headers: errno.h is portable.
11600 2001-11-26 Akim Demaille <akim@epita.fr>
11602 * bin/autoscan.in (used): New.
11603 Use it.
11605 2001-11-26 Akim Demaille <akim@epita.fr>
11607 * bin/autoscan.in (&scan_c_file): Better parsing of CPP
11608 directives.
11609 (&scan_sh_file): Remove a duplicate pattern.
11610 (&check_configure_ac): Use long options.
11611 * lib/autoscan/headers (alloca.h): Check with AC_FUNC_ALLOCA.
11613 2001-11-26 Akim Demaille <akim@epita.fr>
11615 * bin/autoscan.in (scan_c_file): Fix the handling of C comments.
11616 Before, having a line containing the opening of a multi line
11617 comment made the whole line be ignored.
11619 2001-11-26 Akim Demaille <akim@epita.fr>
11621 * doc/autoconf.texi (Using an Autotest Test Suite): New.
11622 (testsuite Scripts): Be one of its subsection.
11623 (Autotest Logs): New.
11625 2001-11-26 Akim Demaille <akim@epita.fr>
11627 Test groups are now run two directories deeper.
11629 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Replace srcdir,
11630 top_srcdir and top_builddir with at_srcdir, at_top_srcdir and
11631 at_top_builddir.
11632 * lib/autotest/general.m4 (AT_INIT): Compute srcdir,
11633 top_srcdir, builddir and top_builddir.
11634 Use `at_*dir' relatively to the directory containing the
11635 suite, use `*dir' when relatively to the current group dir.
11637 2001-11-25 Joseph S. Myers <jsm28@cam.ac.uk>
11639 * doc/autoconf.texi, TODO, lib/autoconf/fortran.m4,
11640 lib/autoconf/functions.m4, lib/autoconf/headers.m4,
11641 tests/atgeneral.m4, tests/tools.at, tests/atspecific.m4: Fix
11642 spelling errors.
11644 2001-11-22 Alexandre Duret-Lutz <duret_g@epita.fr>
11646 * doc/autoconf.texi (Using System Type): Add an example of `case
11647 $host' usage so people quit using `case $target' everywhere.
11649 2001-11-22 Akim Demaille <akim@epita.fr>
11651 * doc/autoconf.texi (Installation Directory Variables): Englishoes
11652 spotted by Jim Meyering.
11654 2001-11-16 Paul Eggert <eggert@twinsun.com>
11656 This patch implements a `long double' suggestion by Oliver Kiddle.
11658 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C)): Make the array
11659 static, to catch errors if the value isn't known at compile-time
11660 and the compiler supports dynamic arrays. Change its name from
11661 `_array_' to `test_array' to avoid potential name clashes.
11662 (AC_C_LONG_DOUBLE): Make it a compile-time test, not a run-time
11663 test. Do not define HAVE_LONG_DOUBLE if `long double' is no
11664 better than double. Catch a bug in GCC 2.95.2 x86.
11665 * doc/autoconf.texi (C Compiler): Document the above.
11666 * NEWS: Likewise.
11668 2001-11-13 Akim Demaille <akim@epita.fr>
11670 * tests/m4sh.at (LINENO): Protect from autom4te's substitution by
11671 hand.
11672 * tests/tools.at: Don't protect dnl, AT_DATA_M4SH does.
11674 2001-11-13 Akim Demaille <akim@epita.fr>
11676 * lib/autotest/general.m4 (AT_INIT): After having run the test
11677 group, go back to the initial directory, not to at_suite_dir.
11679 2001-11-13 Akim Demaille <akim@epita.fr>
11681 * tests/atspecific.m4 (AT_DATA_M4SUGAR, AT_DATA_M4SH)
11682 (AT_DATA_AUTOCONF): Also protect @&t@ from autom4te.
11683 (AT_CHECK_AUTOCONF, AT_CHECK_AUTOHEADER): Pass no --include
11684 option.
11685 (AT_CHECK_CONFIGURE): Use absolute paths.
11686 (_AT_CHECK_AC_MACRO): Create aclocal.m4 with AC_STATE_SAVE in it.
11687 The problem is still the old one: there is no means in M4 (that I
11688 know about) to create a defining macro, because there is no means
11689 to create `$1' etc., therefore, the defining macro ``swallows''
11690 all the arguments meant to the defined macro.
11692 2001-11-13 Akim Demaille <akim@epita.fr>
11694 * tests/atspecific.m4 (AT_DATA_AUTOCONF): New.
11695 (AT_CONFIGURE_AC): Output the definition of AC_STATE_SAVE in
11696 configure.ac.
11697 * tests/aclocal.m4: Remove, as it is no longer used.
11699 2001-11-13 Akim Demaille <akim@epita.fr>
11701 * lib/autotest/general.m4: Change `tests?' into `groups?' in
11702 variable names when referring to a single test group, or to
11703 `suite' when referring to the whole test suite.
11704 `at_last_test' is removed: m4 compute at_format itself.
11705 (at_stdout, at_stder1, at_stderr): New variables.
11706 (AT_CHECK): Use them.
11708 2001-11-13 Akim Demaille <akim@epita.fr>
11710 * lib/autotest/general.m4 (AT_INIT): Be sure to put `.', relative,
11711 in PATH.
11712 Create `testsuite.dir/003/run' instead of `testsuite.003'.
11713 Do it as soon as a test fails, don't wait till the end of the test
11714 suite.
11715 Don't remove $as_me.[0-9]*, since these files no longer exist.
11717 2001-11-13 Akim Demaille <akim@epita.fr>
11719 * tests/tools.at: Use absolute paths, since we are no longer run
11720 in place.
11722 2001-11-13 Akim Demaille <akim@epita.fr>
11724 Now that tests are running in their own private dir, there is no
11725 need to list the files to remove at the end of tests groups.
11727 * lib/autotest/general.m4 (_AT_CLEANUP_FILE, AT_CLEANUP_FILES):
11728 (AT_data_files, at_data_files): Remove.
11729 (AT_CLEANUP, AT_DATA): Simplify.
11730 (AT_INIT): Adjust.
11731 Remove the group dir if !debug && !failed.
11732 * tests/atspecific.m4: Adjust.
11734 2001-11-13 Akim Demaille <akim@epita.fr>
11736 Start a new layout for Autotest: `testsuite' creates
11737 `testsuite.dir' in which the at-check-line etc. files are to be
11738 found, and `testsuite.dir/003' where the test group 3 is run.
11740 * lib/autotest/general.m4 (AT_INIT): at_tests_dir,
11741 at_check_line_file, at_format, at_test_normalized, at_group_dir
11742 are new variables.
11743 Create the directories.
11744 Use absolute paths for at- files.
11745 (AT_CHECK): Adjust.
11747 2001-11-11 Michael Matz <matz@kde.org>
11749 * m4sugar.m4 (_m4_foreach): Make it linear instead quadratic.
11750 (m4_car2): New.
11751 (m4_car): Properly quote arguments.
11753 2001-11-13 Akim Demaille <akim@epita.fr>
11755 * tests/aclocal.m4 (AC_STATE_SAVE): s/LIBOBJS/LIB@&t@OBJS/ to cope
11756 with stricter rules on LIBOBJS.
11758 2001-11-12 Paul Eggert <eggert@twinsun.com>
11760 * lib/autoconf/c.m4 (AC_C_PROTOTYPES): Define __PROTOTYPES too.
11761 * doc/autoconf.texi (C Compiler): AC_C_PROTOTYPES now defines
11762 __PROTOTYPES too.
11764 2001-11-12 Akim Demaille <akim@epita.fr>
11766 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT): Use AC_CHECK_FUNCS.
11768 2001-11-12 Akim Demaille <akim@epita.fr>
11770 * lib/autoconf/c.m4, lib/autoconf/fortran.m4,
11771 * lib/autoconf/functions.m4, lib/autoconf/general.m4,
11772 * lib/autoconf/headers.m4, lib/autoconf/libs.m4,
11773 * lib/autoconf/programs.m4, lib/autoconf/specific.m4,
11774 * lib/autoconf/types.m4: When invoking AC_DEFINE and friends,
11775 specify to what the macro should be defined (typically to 1).
11777 2001-11-12 Akim Demaille <akim@epita.fr>
11779 * lib/autoconf/functions.m4 (AC_FUNC_STRTOD): AC_SUBST POW_LIB.
11780 From Jim Meyering.
11782 2001-11-12 Akim Demaille <akim@epita.fr>
11784 * lib/autoconf/programs.m4 (_AC_PROG_LEX_YYTEXT_DECL): Use
11785 AC_TRY_EVAL to run $LEX, not AC_TRY_COMMAND. This validates the
11786 definition used by Automake where LEX is +/- "${missing} lex" and
11787 `missing' itself contains variables.
11789 2001-11-12 Akim Demaille <akim@epita.fr>
11791 * lib/autotest/general.m4 (AT_INIT): Push KILL at the end.
11792 Now that M4sh pushes BODY, the comments were output at the end of
11793 the test suites.
11795 2001-11-08 Akim Demaille <akim@epita.fr>
11797 * bin/autoreconf.in (&autoreconf): Run aclocal before tracing, so
11798 that we can trace macros from aclocal.m4.
11799 Trace AC_PROG_LIBTOOL, not AM_PROG_LIBTOOL, since the latter is
11800 obsoleted, and redirect to the former anyway.
11801 Reported by Ralf Corsepius.
11803 2001-11-08 Akim Demaille <akim@epita.fr>
11805 * bin/autoreconf.in (&autoreconf): AC_CONFIG_SUBIDRS are to be
11806 processed only if present.
11807 * tests/torture.at (Configuring subdirectories): Use autoreconf
11808 instead of successive calls to autoconf.
11809 Add a nonexistent subdirectory to exercise the patch above.
11810 Reported by Ralf Corsepius.
11812 2001-11-08 Kevin Ryde <user42@zip.com.au>
11814 * doc/autoconf.texi (Limitations of Usual Tools): Note HP-UX cc
11815 doesn't accept .S files.
11817 2001-11-07 Akim Demaille <akim@epita.fr>
11819 * lib/m4sugar/m4sugar.m4 (m4_pattern_forbid): Accepts $2.
11820 * lib/autoconf/general.m4 (AC_INTI): Forbid LIBOBJS.
11821 (_AC_LIBOBJ): s/LIBOBJS/LIB@&t@OBJS/.
11822 * bin/autom4te.in (warn_forbidden): New.
11823 (handle_output): Use it.
11824 Read m4_pattern_forbid with messages.
11826 2001-11-05 Akim Demaille <akim@epita.fr>
11828 * bin/autom4te.in (--normalize): Remove.
11829 * lib/autom4te.in: Adjust.
11831 2001-11-05 Akim Demaille <akim@epita.fr>
11833 * tests/Makefile.am (testsuite): Rename this target as...
11834 ($(TESTSUITE)): this.
11835 From Nicolas Joly.
11837 2001-11-05 Alexandre Duret-Lutz <duret_g@epita.fr>
11839 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): When removing
11840 the --prefix option, also remove it's argument.
11842 2001-11-05 Akim Demaille <akim@epita.fr>
11844 * doc/autoconf.texi (testsuite Invocation): Update.
11845 (Writing testsuite.at): Update.
11847 2001-11-03 Akim Demaille <akim@epita.fr>
11849 * doc/autoconf.texi: s/@code/@command/ where appropriate.
11851 2001-11-03 Akim Demaille <akim@epita.fr>
11853 * lib/Autom4te/General.pm: (&catfile, &canonfile)
11854 (&file_name_is_absolute): New, wrappers around routines from
11855 File::Spec.
11856 Use and export them.
11857 (&find_configure_ac): Optionally take a directory where to look at.
11858 * bin/autoreconf.in (&parse_args): Trim the configure.ac part of
11859 the arguments.
11860 Default @ARGV to `.', not find_configure_ac.
11861 (&autoreconf): Argument is a directory.
11862 Trace AC_CONFIG_SUBDIRS and schedule the subdirs for autoreconf'ing.
11863 * doc/autoconf.texi (autoreconf Invocation): Update.
11865 2001-11-03 Akim Demaille <akim@epita.fr>
11867 * lib/Autom4te/General.pm (@export_vars, @export_subs)
11868 (@export_forward_subs): New.
11869 Add basename, dirname, and fileparse.
11870 (@EXPORT): Adjust.
11871 * bin/autoreconf.in (&autoreconf): Fix call to fileparse.
11872 Don't look for aclocal flags if we already know aclocal is not
11873 used.
11874 Move aclocal.m4t only if it exists.
11875 Reported by Ezra Peisach.
11877 2001-11-03 Akim Demaille <akim@epita.fr>
11879 * bin/autoreconf.in (&parse_args): Work only on the configure.ac
11880 passed on command line, defaulting to ./configure.ac if present.
11881 (&maybe_autoreconf, File::Find): Remove, unused.
11882 (&autoreconf): If autoconf is not used, don't try to trace.
11884 2001-11-02 Akim Demaille <akim@epita.fr>
11886 * configure.ac: Bump to 2.52g.
11888 2001-11-02 Akim Demaille <akim@epita.fr>
11890 Version 2.52f.
11892 2001-11-02 Akim Demaille <akim@epita.fr>
11894 * config/config.guess, config/config.sub, doc/standards.texi:
11895 * config/lispdir.m4: Update from masters.
11896 * configure.ac: Bump to 2.52f.
11898 2001-11-02 Akim Demaille <akim@epita.fr>
11900 * bin/autoreconf.in (&autoreconf): Set `$aclocal_flags' to ''.
11901 Don't run aclocal when aclocal.m4 is not from aclocal.
11902 From Ezra Peisach.
11903 Don't run libtoolize and gettextize if --install is not given.
11905 2001-11-01 Paul Eggert <eggert@twinsun.com>
11907 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): _AS_CR_PREPARE needs to
11908 be invoked before _AS_LINENO_PREPARE.
11909 (_AS_LINENO_PREPARE): Use as_cr_digits and as_cr_alnum rather
11910 than character ranges.
11912 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Fix NLS before
11913 invoking AS_BASENAME. Set the locale variables to 'C' if
11914 possible, as POSIX requires this to get the traditional
11915 behavior.
11916 * doc/autoconf.texi (Special Shell Variables): Describe the above.
11918 2001-10-31 Paul Eggert <eggert@twinsun.com>
11920 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): Do not surround body
11921 with {}, as that triggers a bug in Bash 2.05.
11923 (_AS_LINENO_PREPARE): Use Sed rather than
11924 Awk. Fix the sed prepass to work even if there are multiple
11925 instances of $LINENO on the same line. Do not substitute for
11926 other variables like $LINENOT. Do not check file dates; such a
11927 check is unreliable on sufficiently fast machines, and removing
11928 the check makes the code simpler and more reliable. Check for
11929 output and chmod failures.
11931 * doc/autoconf.texi (Special Shell Variables): Document
11932 the above.
11934 2001-10-31 Akim Demaille <akim@epita.fr>
11936 * tests/Makefile.am (atconfig): Remove this target, Automake
11937 handles it now.
11939 2001-10-31 Akim Demaille <akim@epita.fr>
11941 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Do not
11942 AC_CONFIG_FILES(atlocal) as it means a file atlocal.in *must* be
11943 provided, while it is optional.
11944 * configure.ac: Adjust.
11946 2001-10-26 Paul Eggert <eggert@twinsun.com>
11948 * NEWS, README, configure.ac, lib/Autom4te/General.pm,
11949 lib/Autom4te/Struct.pm:
11950 Require Perl 5.005_03 instead of just 5.005, as some tests fail
11951 with 5.005_02.
11953 * doc/autoconf.texi (Special Shell Variables): Document some
11954 more LINENO gotchas, particularly with respect to the Awk+Sed hack.
11956 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): New macro.
11957 (_AS_LINENO_PREPARE): Use it instead of shell eval, since
11958 eval $LINENO is not portable in practice.
11960 2001-10-24 Akim Demaille <akim@epita.fr>
11962 * lib/Autom4te/General.pm (backname): New.
11964 2001-10-24 Akim Demaille <akim@epita.fr>
11966 * m4/: Remove, merged into...
11967 * config/: here.
11969 2001-10-23 Tim Van Holder <tim.van.holder@pandora.be>
11971 * doc/autoconf.texi (Shellology): Mention the problems with bash
11972 2.05's use of ANSI quoting in its `set' builtin.
11974 2001-10-22 Paul Eggert <eggert@twinsun.com>
11976 * lib/autoconf/functions.m4 (AC_FUNC_STRERROR_R):
11977 Rename ac_cv_func_strerror_r_works to ac_cv_func_strerror_r_char_p,
11978 and rename HAVE_WORKING_STRERROR_R to STRERROR_R_CHAR_P, since
11979 POSIX decided to standardize on the int flavor of strerror_r.
11980 Always do char* test, as there's no reason not to.
11981 Assign to a char* var, to catch strerror_r that returns int*.
11983 * doc/autoconf.texi (Particular Functions):
11984 Document the above changes. Also, document the fact that
11985 AC_FUNC_STRERROR_R defines HAVE_DECL_STRERROR_R.
11987 * NEWS: Mention HAVE_WORKING_STRERROR_R -> STRERROR_R_CHAR_P.
11989 2001-10-20 Akim Demaille <akim@epita.fr>
11991 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): The name of
11992 the executable was missing from the log.
11994 2001-10-20 Akim Demaille <akim@epita.fr>
11996 * lib/Autom4te/General.pm (&update_file): If destination is
11997 unchanged, remove the source.
11998 (&up_to_date_p): Don't be verbose, be debug.
11999 * bin/autoreconf.in: No longer support --m4dir.
12000 (&autoreconf): Display the full path of the configure.ac we are
12001 studying.
12002 Trace it only once.
12003 Be sure to honor --force with gettextize.
12004 Always run aclocal.
12005 * doc/autoconf.texi: Adjust.
12007 2001-10-20 Akim Demaille <akim@epita.fr>
12009 * bin/autoheader.in ($localdir, $m4, $SIMPLE_BACKUP_SUFFIX):
12010 Remove, dead.
12011 * bin/autoreconf.in (&autoreconf): Do not run gettextize when
12012 `intl' is already present, as it refuses unless --force.
12013 (&parse_args): Use -I, --include instead of the old Autoconf
12014 options.
12015 ($localdir, $autoconf_dir): Remove.
12016 (@include): New.
12017 (&maybe_autoreconf): New, to preserve $_ for File::Find.
12019 2001-10-19 Jens Petersen <petersen@redhat.com>
12021 * lib/autoconf/programs.m4 (AC_PROG_AWK): Prefer gawk to mawk.

12024 2001-10-19 Akim Demaille <akim@epita.fr>
12026 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Name the generated
12027 file in @configure_input@.
12028 Don't mention `automatically' in addition to `generated'.
12029 * tests/torture.at (#define header templates): Adjust.
12031 2001-10-19 Akim Demaille <akim@epita.fr>
12033 * lib/emacs/autoconf-mode.el, lib/emacs/autotest-mode.el: In a
12034 comment, explain how to install automatic mode selection.
12035 From Russ Allbery.
12037 2001-10-19 Ezra Peisach <epeisach@zif.mit.edu>
12039 * bin/autoreconf.in (autoreconf): Display the path to the
12040 configure.ac being studied.
12042 2001-10-18 Paul Eggert <eggert@twinsun.com>

12049 (AS_BASENAME_EXPR): New macro.
12050 (AS_BASENAME_SED): Do not assume GNU sed semantics.
12051 (AS_BASENAME): Use 'basename' if that works; then try 'expr';
12052 and fall back on 'sed' only if the other two fail. This makes
12053 AS_BASENAME act more like AS_DIRNAME.
12054 (as_me): Shell-quote the argument of AS_BASENAME, in case $0
12055 contains white space.
12056 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR):

12291 (_AC_COMPUTE_INT): Pass IF-FAILS arg to _AC_COMPUTE_INT_COMPILE.

12336 enough.

12490 $PATH. Also set AUTOM4TE_CFG, so we can process autom4te properly.
12492 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
12494 * bin/autoscan.in: Add 'exec-perl-if-not-run-by-perl'.
12495 * bin/autoupdate.in: Ditto.
12496 * bin/autoheader.in: Reworded a few comments.
12497 * bin/autoconf.in: Reworded help text for a few options.
12498 * bin/autoheader.in, bin/autom4te.in, bin/autoreconf.in,
12499 * bin/autoscan.in, bin/autoupdate.in: Ditto.
12501 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
12503 * lib/Autom4te/XFile.pm (open): Simplified the error message (we
12504 already have $file). Set output files to binary mode (helps avoid
12505 CR issues on DOSish systems).
12507 2001-09-19 Akim Demaille <akim@epita.fr>
12509 * lib/autotest/general.m4: Englishoes.
12510 From Tim Van Holder and Alexey Mahotkin.
12512 2001-09-18 Paul Eggert <eggert@twinsun.com>
12514 * doc/autoconf.texi (Common Shell Constructs): New node,
12515 documenting AS_DIRNAME.
12516 (Limitations of Usual Tools): Refer to it when discussing dirname.
12517 Also, update discussion of POSIX standard to reflect latest draft.
12519 * lib/autoconf/c.m4:
12520 (AC_LANG_INT_SAVE(C)): Also support negative values, down to LONG_MIN.
12522 * lib/autoconf/general.m4 (_AC_COMPUTE_INT_COMPILE):
12523 Do not pass a first argument with leading '-'
12524 to expr, by parenthesizing initial integers that might be negative.
12526 * doc/autoconf.texi (Particular Functions): AC_FUNC_GETPGRP
12527 now merely checks whether it is an error to pass an argument
12528 to getpgrp.
12530 * lib/autoconf/functions.m4 (_AC_FUNC_GETPGRP_TEST): Remove.
12531 (AC_FUNC_GETPGRP): Don't bother with a runtime test. Just check
12532 whether it is a (compile-time) error to pass an argument to
12533 getpgrp. This simpler test supports the revised documentation,
12534 and is all that AC_FUNC_GETPGRP's users really need.
12536 2001-09-18 Akim Demaille <akim@epita.fr>
12538 * doc/autoconf.texi (Limitations of Make) <$<>: New.
12540 2001-09-18 Akim Demaille <akim@epita.fr>
12542 * doc/autoconf.texi (Limitations of Usual Tools) <find>: More about
12543 `{}'.
12544 * lib/autotest/general.m4 (AT_INIT): Adjust.
12546 2001-09-18 Paul Wagland <paul@wagland.net>
12548 * tests/m4sh.at: Ensure that AS_DIRNAME handles '/', '//' and '///'
12549 correctly.
12550 Add test for AS_BASENAME.
12551 * lib/m4sugar/m4sh.m4: Fix AS_BASENAME so that it passes the previous
12552 added test. It now correctly handles /1/2/3/, returning '3' not ''.
12553 Added AS_BASENAME_SED to make the interface the same as AS_DIRNAME.
12554 * tests/base.at: Fixed the expected responses. The old ones were
12555 one line out...
12556 * lib/autoconf/general.m4: Fixed AC_PREFIX_PROGRAM, it now behaves as
12557 the documentation claims it should (and how it behaved in 2.13).
12559 2001-09-18 Akim Demaille <akim@epita.fr>
12561 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): No INIT-CMDS in
12562 the AC_CONFIG_COMMANDS invocation.
12563 This also solves the name clash problems.
12564 Don't set the package's ID.
12565 * lib/m4sugar/Makefile.am (version.m4): Revamp.
12566 No longer to be shipped.
12567 (version.in): Remove.
12568 * lib/m4sugar/m4sugar.m4, lib/autoconf/general.m4,
12569 * lib/autoconf/status.m4: Adjust.
12570 Use `m4_PACKAGE_STRING'.
12571 * lib/autotest/general.m4 (AT_INIT): N-th signature change: now
12572 the only optional argument is the name of the test suite.
12573 Expect `package.m4' to define the package signature.
12574 * lib/autom4te.in (Autotest): Add `package.m4?'.
12575 * tests/Makefile.am (package.m4): New.
12576 * tests/suite.at: ifnames is a victim.
12578 2001-09-18 Akim Demaille <akim@epita.fr>
12580 * lib/autom4te.in (Autoconf): Preselect AM_CONDITIONAL,
12581 AC_LIBSOURCE, AC_CONFIG_FILES.
12582 * lib/autotest/general.m4 (AT_INIT): Don't abort when a tested
12583 program version string doesn't match the package's.
12584 * lib/autoconf/general.m4 (AC_CACHE_VAL): Reestablish the space
12585 after `(cached)'.
12587 2001-09-17 Paul Eggert <eggert@twinsun.com>
12589 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):
12590 Allow expression to return any value that can fit into unsigned long
12591 (not int, as before). Check for output errors.
12593 2001-09-17 Bruno Haible <haible@ilog.fr>
12595 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):
12596 Always include <stdio.h> and <stdlib.h>. Evaluate
12597 the expression in an extra function before these includes. Call
12598 fprintf "%d" only after ensuring the argument is of type 'int'.
12599 Reported by Wayne Chapeskie <waynec@spinnaker.com>.
12601 2001-09-17 Paul Eggert <eggert@twinsun.com>
12603 Fix bug reported by Paul Townsend on AIX 4.3.3.0 with CFLAGS=-O4
12604 or CFLAGS=-O5. In that case, the linker has a relaxed view of
12605 fatal errors, and AC_CHECK_LIB causes it to include libraries even
12606 when they don't exist.
12608 * lib/autoconf/headers.m4 (AC_HEADER_DIRENT): Use AC_SEARCH_LIBS,
12609 not AC_CHECK_LIB, so that we don't use -ldir or -lx if we don't
12610 need it.
12612 * lib/autoconf/specific.m4 (AC_ISC_POSIX): Replace the old, crufty
12613 version with the version used by fileutils 4.1, except use
12614 AC_SEARCH_LIBS, not AC_CHECK_LIB, so that we don't use -lcposix if
12615 we don't need it.
12617 * doc/autoconf.texi (AC_ISC_POSIX): Describe new behavior.
12619 2001-09-13 Akim Demaille <akim@epita.fr>
12621 * tests/base.at, tests/m4sh.at: Be sure to issue the bangshe line
12622 _first_.
12623 Reported by Gerrit P. Haase.
12625 2001-09-13 Akim Demaille <akim@epita.fr>
12627 * lib/autotest/general.m4 (AT_INIT): Reset `AT_victims' so that
12628 m4_defn'ing is valid.

12634 Use it.
12636 2001-09-13 Akim Demaille <akim@epita.fr>

12643 * lib/autoconf/status.m4 (AC_CONFIG_IF_MEMBER, AC_CONFIG_LINKS):
12644 Likewise.
12645 * lib/autoconf/types.m4 (_AC_CHECK_TYPE_REPLACEMENT_TYPE_P)

12647 * lib/autotest/general.m4 (AT_INIT): Rename AT_TESTS_ALL as
12648 AT_tests_all for consistency.
12649 Set at_victims.
12650 (AT_VICTIMS): Similar to AT_KEYWORDS.
12651 (_AT_CLEANUP_FILE_IF): Use m4_match and m4_re_escape.
12653 2001-09-13 Akim Demaille <akim@epita.fr>
12655 * lib/autotest/general.m4 (AT_INIT): Fix stupid bugs.
12657 2001-09-13 Akim Demaille <akim@epita.fr>
12659 * lib/autotest/general.m4 (AT_INIT): Create and remove
12660 `$as_me.[0-9]+' instead of `debug-[0-9]+.sh', so that multiple
12661 test suites can cohabit.
12663 2001-09-13 Akim Demaille <akim@epita.fr>
12665 * tests/mktests.sh: Don't output banners for empty test files.
12667 2001-09-13 Akim Demaille <akim@epita.fr>
12669 Test suites can be run independently of configure.

12771 2001-09-05 Akim Demaille <akim@epita.fr>

12774 the maintainer is dumb enough to do that...
12776 * lib/autotest/general.m4 (AT_SETUP, AT_LINE): Demonstrates your
12777 excellence in M4 quotation: consider `__file__' is active.

12810 New, extracted from main.
12811 Use IO::File wherever possible.

12850 * lib/Autom4te/General.pm (&find_file): Browse the includes in the

12865 * lib/autotest/general.m4 (AT_INIT): Don't pass all the args to

12900 the time stamps.

12940 * bin/autom4te.in (&find_file): Support `FILE?' standing for
12941 optionally `FILE'.
12942 Use -e, not -f, since /dev/null for instance is OK.
12943 (&parse_args): Adjust.
12944 * lib/autom4te.in (Autoconf): Add `acsite.m4?' and `aclocal.m4?'.
12946 2001-08-31 Akim Demaille <akim@epita.fr>
12948 * configure.ac: Also find tested executables in bin.
12949 * bin/autoconf.in, bin/autoheader.in, bin/autoreconf.in,
12950 * bin/autoscan.in, autoupdate.in: Use exclusively the name of the
12951 installed peer executables, only PATH is allowed to resolve it.
12952 Pass `autoconf_dir' via options, not via invisible envvars.
12953 * lib/Autom4te/General.pm (&find_peer): Remove.
12954 * lib/autotest/general.m4 (AT_INIT): `AUTOTEST_PATH=a:b' gives
12955 `abuild:asrc:bbuild:bsrc', not `abuild:bbuild:asrc:bsrc'.
12956 * man/Makefile.am: Let help2man rely on PATH instead of trying to
12957 find the executables for it.
12958 * tests/Makefile.am: Major cleanup. Too lazy to document...
12959 * tests/atlocal.in: Remove all the obscure envvar manipulations.
12960 We only need PERL.
12961 * tests/atspecific.m4, tests/tools.at: Passing --localdir is
12962 indeed related to running the test suite, while passing
12963 --autoconf-dir and others is related to running non installed
12964 Autoconf executables. So don't do that, leave it to...
12965 * tests/autoconf, tests/autoheader, tests/autom4te, tests/autoupdate,
12966 * tests/autoscan: New.
12967 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): Don't
12968 refer to library files: rely on --language.
12970 2001-08-29 Akim Demaille <akim@epita.fr>
12972 * bin/autom4te.in, lib/autom4te.in, bin/autoconf.in:

12975 2001-08-29 Akim Demaille <akim@epita.fr>
12977 * doc/autoconf.texi: Strip the @nodes.
12978 Suggested by Paul Eggert.

12981 2001-08-29 Akim Demaille <akim@epita.fr>
12983 * bin/autom4te.in (&handle_output): s/@__@/@&t@/.
12984 Suggested by Paul Eggert.
12986 2001-08-29 Akim Demaille <akim@epita.fr>
12988 * Makefile.maint (do-po-update): Wget refuses to overwrite files:
12989 download in a tmp dir.
12991 2001-08-29 Akim Demaille <akim@epita.fr>
12993 * lib/autotest/general.m4: s/AT-devnull/devnull/ since there are

13012 * lib/autotest/general.m4: Use
13013 foo=`(command) 2>/dev/null`
13014 not
13015 foo=`command` 2>/dev/null
13016 (at-devnull): Rename as...
13017 (AT-devnull): this.
13018 (--clean): Remove AT-* files too.

13054 * lib/autotest/general.m4 (AT_INIT): Log the command line.

13075 * lib/autoconf/status.m4 (_AC_SRCPATHS): Rename `ac_dots' as
13076 `ac_top_builddir' to mimic Automake's vocabulary, which much more
13077 readable.
13078 Adjust callers.
13079 * doc/autoconf.texi (Configuration Actions): Document the vars
13080 available in commands.
13081 Emphasize the risks of collisions in init-cmds.

13112 (_AC_OUTPUT_LINKS, _AC_OUTPUT_FILES, _AC_OUTPUT_SUBDIRS): Use it.

13114 -> ac_dir).

13116 * lib/autoconf/general.m4 (_AC_INIT_HELP): Ditto.

13148 * m4/strip.m4: New.

13163 * bin/autoupdate.in: Distinguish M4sugar vs. Autoconf macros by
13164 the name of the directory they're in, instead of the filename,
13165 since version.m4 is now in m4sugar, but m4_acversion must not be
13166 classified as an Autoconf macro.
13167 ($input_m4): Don't qualify the path to m4sugar.
13168 Rather, pass autoconf_dir to m4.
13169 * tests/Makefile.am (testsuite): Remove -I top_srcdir, unneeded.

13254 * NEWS, README, README-alpha, TODO, tests/README: This package is
13255 `Autoconf', not `autoconf' (the executable).
13257 2001-08-20 Akim Demaille <akim@epita.fr>

13274 (Examining Syntax) <AC_TRY_COMPILE>

13306 2001-08-20 Akim Demaille <akim@epita.fr>
13308 Huh!?!?! There are still some user EOF tags used, which prevents
13309 their use in AC_CONFIG_COMMANDS for instance...
13311 * lib/autoconf/general.m4, lib/autoconf/specific.m4,
13312 * lib/autotest/general.m4: Rename the EOF tags as `_ACEOF',
13313 `_CSEOF', or `_ATEOF', as appropriate.

13375 * lib/autotest/general.m4 (AT_INIT): Refer to `$as_me.log', not
13376 `$0.log' as for projects where testsuite is in src, we'd have

13391 2001-08-17 Akim Demaille <akim@epita.fr>
13393 * doc/autoconf.texi: Work around Texinfo buglets.
13394 (Transformation Rules): One example is enough, users are expected
13395 to have their brains on. And BTW, use DESTDIR.
13396 (dvar): New macro. Use it.
13398 2001-08-17 Akim Demaille <akim@epita.fr>

13448 (cvs-dist): depends upon it.
13450 2001-08-15 Tim Van Holder <tim.van.holder@pandora.be>
13452 * tests/Makefile.am: Use a clean-local rule to remove
13453 autom4te.cache (it's a directory, not a file.
13454 * Makefile.am: Ditto (but maintainer-clean-local).
13456 2001-08-15 Akim Demaille <akim@epita.fr>
13458 * bin/autom4te.in (@m4_warning): New.
13459 (&handle_m4): Use it.
13460 * tests/m4sugar.at (m4_warn): Pass `-f' to autom4te to ensure the
13461 warnings are issued at each run.
13462 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): M4sugar
13463 is in the src tree.
13465 2001-08-15 Akim Demaille <akim@epita.fr>
13467 * tests/atspecific.m4 (AT_CHECK_AUTOUPDATE): Perl is now required:
13468 don't waste time running `autoupdate --version' works.
13469 * tests/tools.at (autoupdating AC_PREREQ): Likewise.
13471 2001-08-13 Akim Demaille <akim@epita.fr>
13473 * doc/autoconf.texi (ma): Rename this index as...

13526 2001-08-12 Alexandre Duret-Lutz <duret_g@epita.fr>
13528 * tests/semantics.at (AC_C_BIGENDIAN): New test.
13530 2001-08-11 Alexandre Duret-Lutz <duret_g@epita.fr>
13532 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Handle ACTION-IF-TRUE,
13533 ACTION-IF-FALSE, and ACTION-IF-UNKNOWN.
13534 * doc/autoconf.texi (C Compiler Characteristics): Update
13535 documentation for AC_C_BIGENDIAN.
13537 2001-08-11 Alexandre Duret-Lutz <duret_g@epita.fr>
13539 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Guess endianness by grep'ing
13540 magic values from an object file when cross-compiling.
13541 Based on code by Guido Draheim <Guido.Draheim@gmx.de>.
13543 2001-08-10 Akim Demaille <akim@epita.fr>
13545 * bin/autom4te.in (&handle_output): Don't use `grep' with side
13546 effects.
13547 Suggested by Russ Allbery.
13549 2001-08-10 Ralf Corsepius <corsepiu@faw.uni-ulm.de>
13551 * lib/autoconf/general.m4 (_AC_OUTPUT_SUBDIRS): Propagate the
13552 current $prefix to the sub-configures.
13554 2001-08-09 Tim Van Holder <tim.van.holder@pandora.be>
13556 * lib/autoconf/lang.m4: Ignore *.xSYM when looking for an executable
13557 extension (needed on BeOS). Reported by Guido van Rossum.
13559 2001-08-09 Akim Demaille <akim@epita.fr>
13561 * bin/autom4te.in ($icache): Load it only if older than autom4te.
13563 2001-08-07 Akim Demaille <akim@epita.fr>
13565 * lib/autotest/general.m4 (AT_INIT): All the `at-*' are to be
13566 removed.
13567 (at-setup-line): Huh? Be a variable `at_setup_line', not a file.
13568 No need to remove the files before and after the each test, before
13569 each test and at the end of the suite is enough.
13570 Display only the children `times', not the shell's.
13571 If the test failed or was skipped, at-times is not available.
13573 2001-08-07 Akim Demaille <akim@epita.fr>
13575 Always produce testsuite.log, including when there are no
13576 failures. This helps getting information on skipped tests, and
13577 duration of the tests. Err, implement the latter btw.
13579 * lib/autotest/general.m4 (AT_INIT): Set up fd 6 for the log.
13580 Dump information on the first run of each test.
13581 (AT_CLEANUP): Create `at-times' containing the duration of the
13582 test group.
13584 2001-08-07 Akim Demaille <akim@epita.fr>
13586 The use of `dumpstat' revealed that `len' was used although it
13587 should not. m4_text_wrap was using it, but in the Autoconf world
13588 where it is legal. Hence (i) test M4sh in its own world, not
13589 Autoconf's, and (ii), ahem, fix the bug :)
13591 * lib/autotest/general.m4: Be sure the set good quotes, as tracing
13592 does not like `' instead of [].
13593 (AT_INIT): Forbid `^_?AT_'.
13594 And don't output such tokens.
13595 * tests/Makefile.am (CLEANFILES): Add `script', `script.s4g',
13596 `script.as', and `autom4te.cache'.
13597 Remove `empty' and `macro' which are no longer used.
13598 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): New.
13599 * tests/m4sugar.at: Use it.
13600 * lib/m4sugar/m4sugar.m4: Use `m4_len' not `len'.
13602 2001-08-07 Akim Demaille <akim@epita.fr>
13604 * bin/autoconf.in, bin/autoheader.in: --force, -f is a new option.
13606 2001-08-07 Alexandre Duret-Lutz <duret_g@epita.fr>
13608 * bin/autom4te.in (handle_output): Typo in quadrigraph substitution.
13610 2001-08-04 Akim Demaille <akim@epita.fr>
13612 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA, AC_FUNC_ERROR_AT_LINE)
13613 (AC_FUNC_FSEEKO, AC_FUNC_OBSTACK): Use AC_LANG_IFELSE, not
13614 AC_TRY_LINK.
13615 * lib/autoconf/headers.m4 (AC_HEADER_MAJOR): Likewise.
13616 * lib/autoconf/fortran.m4 (_AC_LANG_PROGRAM_C_F77_HOOKS)
13617 (AC_F77_MAIN): Likewise.
13619 2001-08-04 Akim Demaille <akim@epita.fr>
13621 Don't rely on M4sugar outputting the patterns in files, since we
13622 might process the output _without_ running m4, hence without these
13623 files.
13625 * lib/m4sugar/m4sugar.m4 (m4_init): No need for `m4_tmpdir'.
13626 * bin/autom4te.in (@Request::includes): Remove, unused.
13627 (@Request::source): Rename as...
13628 (@Request::input): this.
13629 (@preselect): Add `m4_pattern_forbid' and `m4_pattern_allow'.
13630 (&handle_output): Fetch the patterns from the traces.
13631 `$forbidden' and `$allowed' are constant: use m//o.
13632 (&handle_m4): M4sugar no longer wants `m4_tmpdir'.
13633 (m4_pattern_forbid, m4_pattern_allow): Adjust for tracing only.
13635 2001-08-04 Akim Demaille <akim@epita.fr>
13637 `autoconf && autoheader' is sped up. Now, speed up `autoheader &&
13638 autoconf', i.e., in addition to caching traces, cache the output.
13640 * bin/autom4te.in (Request::cache): Rename as...
13641 (Request::id): this.
13642 ($cache, $icache, $tcache, $ocache): New.
13643 (&handle_m4): Save M4 output in the cache instead of $tmp.
13644 (&handle_output): Adjust.
13645 (&up_to_date_p): Check that the output cache is up to date too.
13646 (top level): Run `&handle_m4' iff force or the cache is invalid.
13647 Run `&handle_output' if the output cache is more recent.
13649 2001-08-04 Akim Demaille <akim@epita.fr>
13651 * bin/autom4te.in ($force): New.
13652 (&parse_args, &print_usage): -f, --force is a new option.
13653 (&handle_output): CPP directives might have spaces after `#'.
13654 (&parse_args): The first file only can be frozen.
13656 2001-08-04 Akim Demaille <akim@epita.fr>
13658 Don't let autom4te compute the `include' traces several times:
13659 first check that the trace cache file is up to date, and then
13660 compare its timestamp with that of the output.
13662 * bin/autom4te.in, bin/autoupdate.in, bin/autoscan.in: Normalize
13663 the preamble. Don't require 5.005 as Autom4te::General does it,
13664 and better yet (use `use', not `require'!).
13665 * lib/Autom4te/Struct.pm: Rename the last occurrences of
13666 Class::Struct as Autom4te::Struct.
13667 * lib/Autom4te/General.pm (File::stat): Use it.
13668 (&mtime): New, export it.
13669 * bin/autom4te.in: Use it.
13670 Declare `$req' is invalid if it is outdated.
13671 Don't declare it valid before saving it if something went wrong.
13673 2001-08-04 Akim Demaille <akim@epita.fr>
13675 Autom4te shall not encode Autoconf data, and preselecting traces
13676 must be proposed to the users.
13678 * bin/autom4te.in (@required_trace): Remove.
13679 (@preselect): New.
13680 (&parse_args, &print_usage): -p, --preselect is a new option.
13681 (&up_to_date_p): Adjust.
13682 * bin/autoconf.in: Preselect some Autoconf macros.
13684 2001-08-04 Akim Demaille <akim@epita.fr>
13686 * tests/tools.at (autoconf --trace: user macros): Check traces on
13687 macros invoked without arguments, and macros invoked with multiple
13688 lines arguments.
13690 2001-08-03 Alexandre Duret-Lutz <duret_g@epita.fr>
13692 * bin/autom4te.in (handle_traces): Fix rewriting of traces without
13693 arguments.
13695 2001-08-03 Akim Demaille <akim@epita.fr>
13697 * bin/autoconf.in ($@): Work around the usual sh bug.
13698 From Nicolas Joly.
13700 2001-08-03 Akim Demaille <akim@epita.fr>
13702 Clean up the handling of the M4 builtins tracing exception.
13704 * bin/autom4te.in (Request::request): Don't complete M4 builtins
13705 trace requests.
13706 (@m4_builtins): Rename as...
13707 (@m4_builtin): this.
13708 (%m4_builtin_alternate_name): New.
13709 (&parse_args): Complete the trace requests with alternate names.
13710 (&handle_traces): Hence no longer do it here.
13711 (&trace_requests): Remove, unused.
13713 2001-08-03 Akim Demaille <akim@epita.fr>
13715 * doc/autoconf.texi (Redefined M4 Macros): Document m4_exit,
13716 m4_if, and m4_wrap.
13718 2001-08-03 Akim Demaille <akim@epita.fr>
13720 * lib/m4sugar/m4sugar.m4 (m4_init): Also forbid `_m4_*' tokens.
13721 (m4_divert_pop): Dump the whole diversion stack when a diversion
13722 mismatch happens.
13723 * bin/autom4te.in (&handle_output): Remember of the first
13724 occurrence of a possibly undefined macro, not the last.
13725 Complain about the possibly undefined macros in the same order as
13726 the appear in the output.
13727 * lib/autoconf/Makefile.am (autoconf.m4f): List its dependencies.
13728 * tests/tools.at (autoconf: forbidden tokens, basic)
13729 (autoconf: forbidden tokens, exceptions): No longer sort
13730 autoconf's stderr, as it is now deterministic.
13731 Check that `dnl' is caught.
13733 2001-08-01 Akim Demaille <akim@epita.fr>
13735 * configure.ac: Bump to 2.52c.
13737 2001-08-01 Akim Demaille <akim@epita.fr>

13747 2001-08-01 Akim Demaille <akim@epita.fr>
13749 * lib/Autom4te/General.pm: Use `carp' and `croak', not `warn' and
13750 `die'.
13751 (&END): New.
13752 * bin/autoconf.in, bin/autom4te.in, bin/autoupdate.in: Remove your
13753 `END', as `Autom4te::General::END' will be triggered.
13754 * bin/autoupdate.in, bin/autoscan.in: Improve error messages accuracy.
13755 * bin/autoupdate.in (File::Compare, File::Copy): Use them instead of

14147 compiler, not the preprocessor.

14190 cross-language link tests can be performed successfully.
14191 (_AC_F77_NAME_MANGLING): Require AC_F77_DUMMY_MAIN. Also put $FLIBS
14192 after $LIBS, for consistency; this should be the general rule since

14196 2001-06-29 Pavel Roskin <proski@gnu.org>

14199 at-stdout and at-stderr instead of removing the newline
14200 from the echo output, which is not guaranteed to work.
14202 2001-06-28 Jens Petersen <petersen@redhat.com>
14204 * aclang.m4 (_AC_PROG_CXX_EXIT_DECLARATION): Only add declaration to

14268 * doc/autoconf.texi (Redefined M4 Macros): New.
14270 2001-06-23 Akim Demaille <akim@epita.fr>
14272 * acgeneral.m4 (_AC_INCLUDES_DEFAULT_REQUIREMENTS): Consider
