invoking AS_BASENAME. Set the locale variables to 'C' if
possible, as POSIX requires this to get the traditional
behavior.
* doc/autoconf.texi (Special Shell Variables): Describe the above.
Awk. Fix the sed prepass to work even if there are multiple
instances of $LINENO on the same line. Do not substitute for
other variables like $LINENOT. Do not check file dates; such a
check is unreliable on sufficiently fast machines, and removing
the check makes the code simpler and more reliable. Check for
output and chmod failures.

lib/Autom4te/Struct.pm:
Require Perl 5.005_03 instead of just 5.005, as some tests fail
with 5.005_02.
* doc/autoconf.texi (Special Shell Variables): Document some
more LINENO gotchas, particularly with respect to the Awk+Sed hack.
* lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): New macro.
(_AS_LINENO_PREPARE): Use it instead of shell eval, since
eval $LINENO is not portable in practice.
Rename ac_cv_func_strerror_r_works to ac_cv_func_strerror_r_char_p,
and rename HAVE_WORKING_STRERROR_R to STRERROR_R_CHAR_P, since
POSIX decided to standardize on the int flavor of strerror_r.
Always do char* test, as there's no reason not to.
Assign to a char* var, to catch strerror_r that returns int*.
* doc/autoconf.texi (Particular Functions):
Document the above changes. Also, document the fact that
AC_FUNC_STRERROR_R defines HAVE_DECL_STRERROR_R.
* NEWS: Mention HAVE_WORKING_STRERROR_R -> STRERROR_R_CHAR_P.
ac_cv_func_strerror_r_char_p, and rename HAVE_WORKING_STRERROR_R to
STRERROR_R_CHAR_P, since POSIX decided to standardize on the int
flavor of strerror_r. Always do char* test, as there's no reason not
to. Assign to a char* var, to catch strerror_r that returns int*.
unchanged, remove the source.
(&up_to_date_p): Don't be verbose, be debug.
* bin/autoreconf.in: No longer support --m4dir.
(&autoreconf): Display the full path of the configure.ac we are
studying.
Trace it only once.
Be sure to honor --force with gettextize.
Always run aclocal.
* doc/autoconf.texi: Adjust.
Remove, dead.
* bin/autoreconf.in (&autoreconf): Do not run gettextize when
`intl' is already present, as it refuses unless --force.
(&parse_args): Use -I, --include instead of the old Autoconf
options.
($localdir, $autoconf_dir): Remove.
(@include): New.
(&maybe_autoreconf): New, to preserve $_ for File::Find.
(AS_BASENAME_EXPR): New macro.
(AS_BASENAME_SED): Do not assume GNU sed semantics.
(AS_BASENAME): Use 'basename' if that works; then try 'expr';
and fall back on 'sed' only if the other two fail. This makes
AS_BASENAME act more like AS_DIRNAME.
