I also ran tests on a Fedora 14 i386 machine. These were not to
successful. Without libffi, build failed during 'make' - see attached
file log-nolibffi-f14-i386.txt. With libffi, a callback caused a seg
fault. I can supply an example but wondered if you were still tweaking
the i386 stuff?
One minor comment: for x86_64, the Foreign exn message for structs and
doubles could, perhaps, usefully indicate libffi is required like it now
does for callbacks.

I've fixed a problem with the non-libffi callback code so it now seems
to compile without libffi. I don't understand the seg-fault with libffi
and Fedora 14. Perhaps there's a problem with the version of the
library in that version. I don't have any easy way of testing it myself
so any debugging you can do would be helpful.
Now I've managed to get libffi working in mingw/msys I'm rather inclined
to remove the non-libffi code completely. The build process for Poly/ML
would then not include the CInterface structure at all if libffi were
not installed, much like X-windows.
