I don't think anyone has tried it before.  Aside from the basic
platform differences you can already guess:

  * Add .exe to executable filenames
  * Use \ as a directory separator instead of /
  * PATH uses ; instead of :

the main obstacles will be:

  * The Makefiles assume some GNU extensions
  * The Top-level drivers are shell-scripts

On the latter point, nhc98 (and hmake) have shell-script drivers to
interpret arguments and call the various stages (pre-processor, Haskell
compiler, C compiler, assembler, linker, etc.).  Since native windows
doesn't have the Bourne shell, you either need to haul in Cygwin's
'bash' (and associated tools like sed, cut, etc) just for that job,
or re-code the scripts (perhaps in Haskell?).
