    This isn't an option on Solaris 10, as it doesn't ship with a
    "system ffi", unfortunately.  (That being said, after building
    the latest libffi with Sun C, I do use --with-system-ffi in
    order to override the building of Modules/_ctypes/libffi.)

    Sun CC is supported by libffi for SPARC only.  You're right
    regarding x86/x64 though; libffi explicitly doesn't support
    using anything other than gcc on Solaris if it's x86.

    (Unfortunately, my only SPARC boxes are running Solaris 9
     and 10.  I don't have new-enough SPARC CPUs that can run
     Solaris 11.  If I did, this would probably be moot, as I
     could just use the system libffi Sun provide.)

    Side note: on my Solaris 11 x64 box, --with-system-ffi works
    (once -I and -L are tweaked), but test_ctypes still fails if
    you're building with Sun CC.
