* acfunctions.m4 (AC_FUNC_WAIT3): Use `break' to silent some
warnings from compilers.
* aclang.m4 (_AC_LANG_COMPILER_GNU): Log the version information
for all the compilers, not only GNU. Hence move from here...

Automake), include the separator themselves.

Pass precious variables which are set to config.status.

(run_m4f): Remove.
Update remainder of script to use them.

whether fseeko and ftello are properly declared.
* acfunctions.m4 (AC_FUNC_FSEEKO): New macro, which worries about
fseeko (and presumably ftello). Do not set _XOPEN_SOURCE; that
causes too many problems in practice.
* acfunctions (fteelo, fseeko): Trigger AC_FUNC_FSEEKO.

(_AC_INIT_HELP): Likewise.
(NEWS): Note checking for configure.gnu.
* doc/autoconf.texi: Document checking for configure.gnu when
recursing subdirectories.
AC_CONFIG_COMMANDS, AC_CONFIG_FILES): Use a shell variable instead
of an m4 variable to store what must be done, so that sh
conditionals are honored.
(_AC_OUTPUT_LINKS, _AC_OUTPUT_HEADERS,
_AC_OUTPUT_COMMANDS, _AC_OUTPUT_FILES): Adjust.
* tests/semantics.m4: Test the four AC_CONFIG sisters.
* doc/autoconf.texi (Configuration Actions): Promote the use of

Fix this bug, implement the solution provided by Axel Thimm,
and test AC_REQUIRE.
* acgeneral.m4: Document this implementation.
(_AC_DEFUN_PRO, _AC_DEFUN_EPI, AC_REQUIRE): Be sure that macros
are emitted in the same order as they are expanded.
(AC_REQUIRE): Forbid being calling out of an AC_DEFUN'd macro (in
particular the top level).
