My initial thought was to use the cpp-style ifdefs I've seen elsewhere to mask those unsupported features on those particular systems. But Hugs at least doesn't support that, and I've found it extremely difficult to find a list of predefined macros for the other systems anyway.

I thought Hugs does support preprocessing, with the -F option? 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 Regards, Malcolm
