It seems to work OK on AIX.  (Recall, AIX has a 32-bit and 64-bit
compiler in the same 32-bit executable---that's the reason that the
patch believes it needs a 64-bit HOST_WIDE_INT.)

I do know that there are certain things that don't work, though, like
creating > 2G objects or using TImode.

I don't think anyone believes that this should _not_ work; it's just
that it may not be the best choice, and even if it is this isn't the
time to switch now.
