Well, I had looked at that before, but that fact that none of the
example code actually calls it is a bit disconcerting.
However, I forged ahead and borrowed the gtk-init function and
substituted an ff-call. I wound up with another unhandled exception:
Welcome to OpenMCL Version (Beta: Darwin) 0.14.2-040506!

(ff-call (external "_gtk_init") :address argcp :address argvp))))
? (gtk-init '"junk1" '"junk2")

What should that ff-call look like?
