creating the awk substitution script, handle one input line at a
time, so that the maximum length of a substituted (multi-line)
value is not limited by the size of the sed pattern space.
The trade-off is a slightly repetitive sed script.
* doc/autoconf.texi (Limitations of Usual Tools): Branch labels
can only have up to 7 characters, due to Solaris 10 /bin/sed.
* tests/torture.at (Substitute a 2000-byte string): Increase the
test with several long lines, they should not be caught by sed
limits any more.
years and is too hard to maintain now. The last straw was
reported by Jerker Baeck in

* NEWS: AC_FUNC_SETVBUF_REVERSED is now obsolete.
* doc/autoconf.texi (Particular Functions): Move
AC_FUNC_SETVBUF_REVERSED from here...
(Obsolete Macros): ... to here. Say that it does nothing now.
* lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
Turn into (almost) a no-op.
the number of substituted variables by using awk instead of sed
for the bulk of the substitutions.
* NEWS: Mention this.
* doc/autoconf.texi (Setting Output Variables): `|#_!!_#|' is also
forbidden in the output (and thus input) file.
* lib/autoconf/status.m4 (_AC_AWK_LITERAL_LIMIT): New macro.
(_AC_OUTPUT_FILES_PREPARE): Instead of several sed scripts,
generate just one large awk script for substitutions,
eliminating much of the earlier complexity, while adding some
new complexity. Only expand the substitution templates at
configure time, for smaller configure script size. If
_AC_SUBST_FILES are used, test 'awk' for working getline support
at config.status time. If absent, interpolate through the
shell. The awk script was written with much help
from Paolo Bonzini and Paul Eggert.
(_AC_SED_CMD_NUM, _AC_SED_DELIM_NUM, _AC_SED_FRAG): Removed.
(_AC_SED_FRAG_NUM): Likewise.
(_AC_SUBST_CMDS): Renamed from...
(_AC_SED_CMDS): ...this.
(_AC_OUTPUT_FILE): Use _AC_SUBST_CMDS.
* tests/torture.at (Substitute a 2000-byte string): Also
substitute a line with 1000 words, and a variable with several
long lines.
(Substitute and define special characters): Test awk special
characters, and put substitution input strings `@foo@' in the
output, to test that no recursion happens; test several other
combinations from Paolo Bonzini.
code for --enable, --disable, --with, and --without to...
(_AC_INIT_PARSE_ENABLE): ... a new macro.
* doc/autoconf.texi (Package Options):
* NEWS: Document that AC_ARG_ENABLE allows dots, too.
2006-11-13 Bruno Haible <bruno@clisp.org>
* lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): For --with, --without
options, transliterate also dots to underscores.
(_AC_ENABLE_IF): Transliterate also dots to underscores.
* doc/autoconf.texi (External Software): Document that AC_ARG_WITH's
first argument may also contain dots.
* doc/autoconf.texi (Caching Results): Likewise.
* lib/autoconf/general.m4 (_AC_CACHE_CHECK_INT): Renamed from
AC_CACHE_CHECK_INT, since it's no longer public.
* lib/autoconf/types.m4: All uses of AC_CACHE_CHECK_INT changed.
* tests/base.at (AC_COMPUTE_INT): Test this, not AC_CACHE_CHECK_INT.
* build-aux/install-sh (posix_mkdir): Reject FreeBSD 6.1 mkdir -p -m,
which incorrectly sets the mode of an existing destination
directory. In some cases the unpatched install-sh could do the
equivalent of "chmod 777 /" or "chmod 0 /" on a buggy FreeBSD
system. We hope this is rare in practice, but it's clearly worth
fixing. Problem reported by Alex Unleashed in
<http://lists.gnu.org/archive/html/bug-autoconf/2006-10/msg00012.html>.
Also, don't bother to check for -m bugs unless we're using -m;

2006-10-11 Stepan Kasal <kasal@ucw.cz>
* lib/m4sugar/m4sh.m4 (AS_BOURNE_COMPATIBLE): Move the

(_AS_BOURNE_COMPATIBLE): ... to this new macro.
(_AS_RUN): Call _AS_BOURNE_COMPATIBLE, not AS_BOURNE_COMPATIBLE.
shel scripts no longer export BIN_SH, due to configuration
hassles with this.
* lib/m4sugar/m4sh.m4 (AS_BOURNE_COMPATIBLE): Don't set BIN_SH

(_AS_DETECT_BETTER_SHELL): Don't look in /usr/bin/posix.
Use AS_EXECUTABLE_P rather than test -f.
(AS_SHELL_SANITIZE): Set DUALCASE.
(AS_EXECUTABLE_P): Just invoke as_executable_p.
(_AS_TEST_PREPARE): Default to test -f, rather than to nothing.
argument to `--prefix' for sub-configure scripts.
Pass `--silent' to sub-configure scripts.
* tests/torture.at (Configuring subdirectories): Add tests
for both changes.
* doc/autoconf.texi (Setting Output Variables): Fix example to
not show `--silent' being passed to a `configure' re-run.
* lib/autoconf/general.m4 (AC_CONFIG_MACRO_DIR): Do not check
for the existence of the directory at configure-time. That's
too late, anyway, and possibly the directory isn't part of the
distribution. Problem reported by Stefan Seefeld.
f90/f95 because the latter drivers of AIX Fortran 9.1 do not
accept files with extension `.f'. For consistency, also prefer
xlf over f77.
* doc/autoconf.texi (Fortran Compiler): Remove mention of bug
from last patch.
old AC_COMPUTE_INT, which now behaves like _AC_COMPUTE_INT
except the first two arguments are reversed.
* doc/autoconf.texi (Caching Results): New macro AC_CACHE_CHECK_INT.
(Generic Compiler Characteristics): AC_COMPUTE_INT no longer
caches nor outputs a diagnostic. Suggested by Bruno Haible.
* lib/autoconf/general.m4 (AC_CACHE_CHECK_INT): New macro,
equivalent to the old AC_COMPUTE_INT.
(AC_COMPUTE_INT): No longer caches or reports. New signature.
All uses changed to AC_CACHE_CHECK_INT.
* tests/base.at (AC_CACHE_CHECK_INT): New test.
* tests/mktests.sh (ac_exclude_lsit): Add AC_CACHE_CHECK_INT.
and AC_REPLACE_FNMATCH are now obsolescent in Autoconf. New
programs should use their Gnulib counterparts.
* doc/autoconf.texi (Particular Functions): Likewise.
(Macro Names, testsuite Invocation): Replace uses of these
obsolete macros with uses of non-obsolete macros.
* doc/autoconf.texi (Particular Programs): YYTEXT_POINTER is
for the default, which the user can override.
* lib/autoconf/programs.m4 (AC_PROG_LEX): Let _AC_PROG_LEX_YYTEXT_DECL
deal with LEXLIB.
(_AC_PROG_LEX_YYTEXT_DECL): Handle caching correctly; the old code
didn't work if some values were cached but not others. Test for
broken lex libraries like native ia64-hp-hpux11.22; see
<http://sources.redhat.com/ml/binutils/2003-12/msg00337.html>, and
work around the problem by preferring an empty LEXLIB to -lfl or
-ll. Let the user set LEXLIB='' to indicate no library needed.
