C, GCL interface

[Edward Kmett]

The major concern that I would have is that if GCL or any of those math
libraries uses GMP behind the scenes, which they probably do, then things
will just start crashing on you, because GHC hooks the GMP allocator and
will just start making the limbs of their numbers disappear.
