Does JHC support unbounded integers? I get different results from

Yeah, the libraries that come with jhc currently don't have an arbitrary precision integer library. This isn't so much an issue with jhc as the libraries it ships with, as jhc itself is agnostic about such library issues. Once a suitable Integer library gets written (either in pure haskell, or as a binding to an external C library) then I will include it.
Is there a problem with GMP? Or is it just that the Integer support is baked into the ghc runtime? mark
