And these issues /may/ have been fixed since then.

What we need is concrete bug reports of issues and test cases to observe
whether or not to prefer ffcall over libffi for certain platforms.

But unless we have that data, I agree that we should prefer libffi by
default.

Last release of ffcall: ~February 2006
http://www.haible.de/bruno/packages-ffcall-README.html

Last release of libffi: November 11, 2008
http://sourceware.org/libffi/

Any issues we find with libffi should be fixed either in libffi or our
usage of it.

Cheers,
David
