Cabal + WinHugs + Windows + No C Compiler

My worry is that MinHugs has Cabal (as will pretty much every single
Haskell compiler), but Win32 is a lot less commonly installed - for
example GHC has moved it into Extralibs. I'd hate to introduce such a
big dependency just for one single FFI function.

Thanks
