* lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
* lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_TESTS): On subsequent
calls, for a new language, only check that the compiler works.
(AC_NO_EXECUTABLES): Change the redefinition of
_AC_COMPILER_EXEEXT_TESTS so that on subsequent calls, it checks
that the new language's compiler works if ac_no_link=no, and
does nothing otherwise.
Factor out the warning to...
(_AC_TOOL_WARN): ... this new macro; use `cross_compiling'.
* tests/local.at (AT_CHECK_MACRO_CROSS): Avoid this warning.
* tests/semantics.at (AC_C_BIGENDIAN): Likewise.
`expr' away if there is nothing to do.
< --keywords >: Simplify and robustify argument handling.
Revert erroneous comment from 2005-08-23. Extend to allow
keyword negation with `!'.
Update help message. Remove broken code to prevent running
tests multiple times.
* doc/autoconf.texi (testsuite Invocation) < --keywords >:
Update and fix the documentation accordingly.
* tests/autotest.at (Keywords): Renamed to..
(Keywords and ranges): .. this. Extended to make sure negated
keywords, keywords taken from AT_SETUP arguments, and numeric
test ranges work, and that matching is case-insensitive.

(AC_CHECK_SIZEOF): Likewise.
Also fix quoting error in `AC_MSG_FAILURE' arguments.
* tests/semantics.at (AC_CHECK_ALIGNOF struct, AC_CHECK_SIZEOF

Also fix quoting error in `AC_MSG_FAILURE' arguments.
HP-UX sed is 99 commands, not 100.
(_AC_OUTPUT_FILES_PREPARE): Do not count the `}' of an
_AC_SUBST_FILES fragment. Separate `{' and `r' commands by
newline for portability.
* tests/torture.at (Torturing config.status): Also test 100
AC_SUBST_FILE invocations. Fix test to actually verify the
AC_CONFIG_FILES output.
* doc/autoconf.texi (Limitations of Usual Tools): Document HP-UX
command, label, and read-file `r' limits. Unify HP-UX spelling.
(AT_INIT): Use it, to remove arbitrary limit of 999,999 test
cases, and to work around Tru64 expr bug.
* doc/autoconf.texi (Limitations of Usual Tools): Mention Tru64
expr bug that turns the result of a regex match into a number if
possible.

* doc/autoconf.texi (Programming in M4sh): Adjusted.
* tests/m4sh.at (AS_IF and AS_CASE): Test this. Also make sure
both macros are defun'ed so that required macros are evaluated
outside.
document m4_for, m4_foreach, m4_foreach_w, and mention
obsolete AC_FOREACH.
(Obsolete Macros): Document AC_FOREACH.
* lib/m4sugar/m4sugar.m4 (_m4_for): Fix declaration comment.
(m4_for): Fix to never loop (almost) endlessly, work correctly
with arithmetic expressions in arguments, a step of zero or
non-integer multiple of the interval, and avoid integer
overflow.
* tests/m4sugar.at: New test for m4_for, m4_foreach, and
m4_foreach_w.
