(AC_FUNC_FNMATCH): Use it. Test only for POSIX conformance,
not for GNU extensions; this undoes part of the 2000-11-03 change,
reverting to 2.13-compatible behavior.
Add new optional argument DIR.
(AC_FUNC_FNMATCH_GNU): New macro.
If prototypes are supported, use them to check this at compile-time,
instead of trying to check it at run-time. If we must do a run-time
check, assume that setvbuf is standard when cross-compiling, as
nonstandard setvbuf occurs only on ancient and unlikely hosts.
and ac_subst_vars be sh variables containing the list of
AC_SUBST_FILES'ed and AC_SUBST'ed identifiers. Output them in the
DEFAULT diversion.
(_AC_INIT_PREPARE): Use them to log them.
(_AC_SUBST, _AC_SUBST_SED_PROGRAM): Remove.
(AC_SUBST, AC_SUBST_FILE): Instead of buliding the
_AC_SUBST_SED_PROGRAM, store the list of output files/variables in
_AC_SUBST_FILES and _AC_SUBST_VARS.
* lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Adjust.
workaround for ${1+"$@"}.
* doc/autoconf.texi (Shell Substitutions): Explain it.
From Oliver Kiddle and Peter Stephenson.
Have M4sh perform minimal shell sanitizing.
* lib/m4sugar/m4sh.at (AS_SHELL_SANITIZE): Split the `_AS_PREPARE_*'
part into...
(_AS_PREPARE): this new macro.
(AS_PREPARE): New.
(AS_INIT): Invoke AS_SHELL_SANITIZE.
* tests/m4sh.at (AT_DATA_LINENO): Use _AS_PREPARE.
Adjust Autoconf and Autotest.
* lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Don't invoke
AS_SHELL_SANITIZE, AS_INIT did it, but invoke AS_PREPARE.
* lib/autotest/general.m4 (AT_INIT): Likewise.
* lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
Invoke _AS_PREPARE (not AS_PREPARE) in addition to
AS_SHELL_SANITIZE.
Use this M4sh to generate Autoconf's shell scripts.
* tests/wrapsh.as: New, precursor of wrapsh.in.
* tests/Makefile.am: Include lib/freeze.mk to get the dependencies
on Autotest and M4sh.
($(TESTSUITE)): Use $(autotest_m4f_dependencies).
(wrapsh.in): New target.
* bin/autoconf.as: New, precursor of autoconf.in.
(autoconf.in): New target.
(_AC_CONFIG_COMMAND, _AC_CONFIG_LINK): New.
Use dnl, not the KILL diversion.
Extracted from...
(AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_COMMANDS)
(AC_CONFIG_LINKS): here.
Adjust.
Don't use the KILL diversion, as it kills spurious output, which
results in failures being hidden.
Use m4_defn where appropriate.
(AC_CONFIG_IF_MEMBER): Kill the real bug: a spurious parenthesis
after the second argument.
Use m4_defn.
* lib/autom4te.in (Autoconf, Autotest, M4sh): Don't pass --warning
syntax, as it is provided by M4sugar.
* tests/torture.at (Multiple AC_CONFIG_FILES): New.
(_AC_COMPILER_EXEEXT_REJECT): New.
Also recognize *.bb and *.bbg as compilation byproducts.
(_AC_COMPILER_EXEEXT_DEFAULT, _AC_COMPILER_EXEEXT_O)
(_AC_COMPILER_OBJEXT): Use them.
Fixes Debian #138666.
Create at_test_all by a series of assignments,
not by a single assignment of a long string. The latter causes ksh
version 11/16/88g to silently misbehave on OpenServer 5.0.6a,
presumably because of a buffer overrun.
(AS_MKDIR_P): Require it. Use mkdir -p if available, falling
back on AS_DIRNAME to compute prefixes otherwise; this is
roughly what mkinstalldirs does. That way, we need not have
our own filename disassembler. The old disassembler did not
work with Solaris 8 dtksh, which is ksh Version M-12/28/93d.
