Browse Source 
2004-09-07  Frank Ch. Eigler  <fche@redhat.com>

	* configure.ac: Look for pwd.h, grp.h, netdb.h headers and functions.
	* mf-hooks2.c (strerror): Unregister previous string returned by
	previous strerror.
	(getlogin,cuserid,getpwnam,getpwuid,getgrnam,getgrgid): New wrappers.
	(getservent,getservbyname,getservbyport,gai_strerror): Ditto.
	* mf-runtime.h.in: Add redefine_extname pragmas for them all.
	* mf-runtime.c (__mf_describe_object): Clarify object life status.
	* testsuite/libmudflap.c/pass48-frag.c, pass49-frag.c, fail32-frag.c:
	New tests.
	* configure, config.h.in: Regenerated.
