All those patches seems to work with gcc-4.2.2. Now I'm doing some tests, but it looks like gcc-4.2.2 works perfectly with bare gentoo-patches from gcc-4.2.1 + those patches from deb and oe patches.

i'm not about to start merging crunch crap ... it's a pita to maintain

adding fixes for specific PRs is fine
