Peter,
Looking at the libffi/src/powerpc/ffi.c file, I assume that
I should have the same...
*next_arg++ = (unsigned long)(char *)ecif->rvalue;
in ffi_darwin.c instead of the current...
*next_arg++ = (unsigned)(char *)ecif->rvalue;
Does that sound right? If so, I'll file a PR for this
as well and do a test build tonight.
Jack
