It might be a "A Good Thing" in terms of being "pure", but it's different than the behavior on Solaris, HP-UX, Tru64 UNIX, IRIX, and Linux. It's just not worth it being that different today. AIX certainly has no advantage because of it. -- albert chin ([EMAIL PROTECTED]) _______________________________________________ http://lists.gnu.org/mailman/listinfo/libtool
