Created attachment 132806 [details, diff] arm-pragma-pack.patch arm-pragma-pack.patch from debian sid
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
4.2.2 includes a bunch of patches
