CPUTYPE causes "-march" to be applied, so it can affect compatibility. AFAIK both setting do affect world and kernel because CFLAGS can cause a build to fail, and I've seen matching march settings in kernel builds. > Or are those settings relevant to the > compilation process only?

It can be either, -O2 is related to execution, -pipe speeds-up compilation. _______________________________________________ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]"
