Hello,

Currently I'm using gcc 4.5.4 which doesn't allow me to use some features of i7 sandy bridge (i must set -march=core2... in make.conf). How to migrate to the newest stable version supporting that flag? Is it safe? Should I upgrade something else too?

I tried to emerge -s gcc but it gives no results.
