You're right, it works.  Thanks for helping.

I can't say for sure, since I used a Gentoo ebuild, but I believe I am
using libffi.  Here is the quote in gnustep-base-1.10.3.ebuild that
makes me think it is libffi:

    # why libffi over ffcall?
    # - libffi is known to work with 32 and 64 bit platforms
    # - libffi does not use trampolines
