Is it now safe to use p4 by recommendation? Out of curiousity how about athlon-4? Many thanks -- gentoo-dev@gentoo.org mailing list ^ permalink raw reply [flat|nested] 2+ messages in thread

I have not have the chance to check them all yet (and anyhow already getting things ready for gcc-3.3). As for athlon-4 ...
