Comment (by ross):

 Another possible solution:
  * Cabal currently puts preprocessor output in another directory, which it
 adds to the search path for ghc --make.  If modules that don't require
 preprocessing were treated as having an identity preprocessor, and just
 copied into that directory (if they're listed in the .cabal file), then
 only that directory need be on the search path for ghc --make, and
 unlisted modules would generate compile errors.
