I thought Hugs does support preprocessing, with the -F option?
Yes, but it requires an external preprocessor program to be available.
(Enter cpphs.)
#g

The usual cpp macros are:
__HASKELL98__ # supports at least the '98 standard
__GLASGOW_HASKELL__ = 504, 602, etc
__HUGS__
__NHC__
__HBC__
You might also occasionally see
__HADDOCK__ # for documentation-only preprocessing
__HAT__ # for the Hat tracer
