The brazilian portuguese translation of the gcc upgranding guide (http://www.gentoo.org/doc/pt_br/gcc-upgrading.xml) and the handbook (http://www.gentoo.org/doc/pt_br/handbook/handbook-x86.xml) are outdated.
So update them.
I realize they are outdated - I wish I could keep them up to date, but unfortunately I am swamped with work and college and I simply do not have the time. If you were to update them, I could help reviewing and publishing them, but I am just to scarce of myself these days to be proactive in maintaining them. Sorry.
