oh, I meant that was a limitation of my backend, not ghc. jhc has
primitive types for all possible c types, like uint32_t and uint16_t etc
are distinct unboxed types. ghc seems to work mostly by boxing Int# and
doing the appropriate bit narrowing in the library. 

My current solution is just to map all primitive types to Int#. even
though it gives incorrect results it seems to work well enough for
testing the back end. I am not sure what my long term solution will be,
probably to auto-generate some ghc code to simulate all the appropriate
primitives the jhc front end expects to exist.
