I am no where near my powermac g5 but as soon as I can I'll climb back
in and see what I can get done with libffi. The entire objective of my
efforts was to get a clean bootstrap of GCC 4.6.2 for ppc970 and then
to work towards GCC 4.7.0RC1 etc.  Thus this is a bit of a road block
that must be cleared on ppc.
