Sounds very cool.  *However* the output will not be portable, since the
FFI preprocessors work by inlining constants.

It also sounds pretty easy.  Look at the API docs (Distribution.* in
your nearest GHC documentation bundle), see if it can be done in a
stand-alone tool, if not by all means submit a ticket.
