When compiled at -m64 on Darwin PPC, we get the warning...
../../../../gcc-4.2-20060915/libffi/src/powerpc/ffi_darwin.c: In function
'ffi_prep_args':

*next_arg++ = (unsigned)(char *)ecif->rvalue;
It would appear that we should be doing the same thing as in libffi.c...

I will be testing this fix tonight and seeing if it improves the current
level of failures for the libffi testsuite at -m64 on Darwin PPC.
