I installed beecrypt and I realize it uses mcpu=athlon-xp (from my make.conf) and also mcpu=pentiumpro (from ????). Won't this mcpu flag override my athlon-xp or may produce a broken binary ? Reproducible: Always Steps to Reproduce: 1.have something different than pentiumpro in make.conf 2.emerge beecrypt 3.

Good catch, thanks. Will not break things though, but it is not quite right for Gentooers Ok, changed it so it scans your CFLAGS and uses the ones which are set.
