I've tested the libffi patch and it works fine.  I will be checking it
in on the trunk and the branch shortly.

Thanks a lot for this work!  Now PPC is one of our fully supported

I haven't done anything with the first patch.  It would have to be
examined by the regular gcc hackers.  Maybe it has been already?
