I installed gentoo yesterday for the first time from stage1, as I saw duron was in make.conf as an optimization and no duron stage2 or stage3 were available. I was disappointed to find duron is not a valid optimization for gcc as make.conf says. It should be removed from the list in make.conf.. The URL shows the real list.
a better thing would be to steal this: http://www.freehackers.org/gentoo/gccflags/ and maybe put it in a manpage byitself or something
Do you know what to do with this? Cheers, //zhen
make.conf has been updated
