I've gone ahead and committed changes to incorporate patches for recent
upstream commits. After a full build, I'm a little uncomfortable about
the gcc patch. It is 7648 lines and the build shows several unexpected
failures that were not present before.

-------------------
How should we approach this? The easy way is to not apply the new patch.
Additionally I do not know what the patch is supposed to fix.
How should we go on this? I will hold off on -rc2 until we can reach a
consensus.
