+ * 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.
+
2004-08-03 Dale Johannesen <dalej@apple.com>
* mf-runtime.c: Conditionalize POSIX_SOURCE for Darwin.
