configure.ac: Look for more headers & functions.

2004-10-04  Frank Ch. Eigler  <fche@redhat.com>

	* configure.ac: Look for more headers & functions.
	* mf-hooks2.c (getmntent, inet_ntoa, getproto*): New wrapper functions.
	* mf-runtime.h.in: Add new "#pragma redefine_extname"s for them.
	* mf-runtime.c (options): Clean up integer signedness warnings.
	(main): Add a declaration to fix a warning.
	* mf-hooks3.c (pthread_exit): Add not-reached exit() to wrapper.
	* configure, config.h.in: Regenerated.
