Thanks, I'll get on with testing then. As you can see I was somewhat unsure
of the fix, I initially had patched libffi for MIPS n32 until I realised
the ffi_arg quirk. It seems a few projects have fallen foul of this with
32-bit integers and 64-bit architectures. Libguile had the same issue some
time ago.
