The patch itself is okay, but I am surprised that Apple wants to
make this change.
How can Darwin run MacOS code, which was based on the AIX ABI using R2, in
a compatibility box if R2 is trashed by the rest of the system? How can
one mix code produced by GCC and IBM's compiler in Darwin?
Is this an effort to prevent all other PowerPC OSes from running
Darwin apps?
