No deep reasons AFAIK, just the usual cross-compiler portability  
issues, and lack of time to invest.

The unix package uses autoconf, which is a bit of a large initial  
barrier, and also parts of it rely on at least some GHC internal  
representations (e.g. of Handles).  Apart from that, it is a large  
API, and would probably take considerable time to work through, fixing  
things up by hand.

The win32 package would require me to find a Windows box to test the  
bindings on, and I do not have ready access to one.
