Well, classes are over for the semester, which means I have more time to work on things now. First thing to do is get gcc-4.0.2-r2 put together and in the tree. I just backported a patch from gcc-4.1 to fix an ICE that was introduced by another patch I had added. Hopefully when I wake up later I see that all of the `emerge -e world`s I started have successfully completed. I'll give it a few days before putting it out just to make sure there are no code generation regressions (doubtful, but possible). This version will hopefully be added to ~arch soon after it is put in the tree. Most of the tree seems to be gcc-4.0 safe, so the transition shouldn't be too bad.

We are still looking for arch testers (and possibly if you are good, arch dev :) ). Let me know via email if you are interested in helping out, or stop by #gentoo-x86 on Freenode. The more people we get to help out means the less work everyone else has to do. :)
