does Hugs understand C preprocessor macros? If not, your approach would be bad for me since I try to stay Hugs-compatible.

Well, Hugs itself doesn't understand CPP macros (neither does GHC), but you can use Hugs' -F<cmd> flag to pipe the source files through <cmd> before Hugs actually sees them. GHC has two related options, -pgmP <cmd> and -cpp. FYI: The hierarchical libraries are full of CPP stuff to handle the differences between various platforms and/or Haskell system, but the Hugs distributions usually come with preprocessed versions, so you don't necessarily need cpp. Cheers, S.
