Peter,
Wouldn't we want something like...

Unfortunately _powerpc64_ doesn't seem to be defined in boehm-gc
for that directory, but if I manually force...
unsigned long FindTopOfStack(unsigned long stack_start) {
to be used at -m64, the compile warning disappears. We have
the same issue in gcc-4.2-20060915/libffi/src/powerpc/ffi_darwin.c
(which might explain why it fails so many tests at -m64).
