This is OK.  On the issue of merging from trunk, it won't be to this
branch, since this branch is intended to track gcc-4.4 (yes, I'm a bit
behind on my merging...).

We may need to create a separate branch that does track trunk, it will
depend on how soon I can get to the point where I'm ready to merge and
how far trunk has diverged from this branch.
