Indeed, we definitely should declase it as CInt -> CInt. Otherwise we could get all sort of exciting cross-platform troubles. > I don't know if it works. I don't have GHC 2.4 (yet).

I think this definitely requires significant testing (or confirmation from someone who really knows what they're talking about), and won't make it into 1.0.4.
