I took your patch and moved into the portable side of things so that
other Lisps can benefit from this. I've tested it on Lispworks and
Allegro and it passes the long-long tests.

Yeah, regular functions won't work either. Will add this to the docs.

I haven't tested this with anything other than cffi-tests, but it has
a couple of struct tests and they're passing.
