Thanks for the report. gcc-3.0 has been out for over 3 years, so I think it's not worth much trouble to work around that bug. But if you're interested, an autoconf run-test is probably the way to go. It'd make the configure script detect the problem and exit nonzero. _______________________________________________ Bug-coreutils mailing list Bug-coreutils@gnu.org http://lists.gnu.org/mailman/listinfo/bug-coreutils
