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,
