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.
