Ian Lynagh wondered: | is there a nicer way to do something like | | #ifdef __GLASGOW_HASKELL__ | #include "GHCCode.hs" | #else | > import HugsCode | #endif I usually make two directories: Hugs/ Ghc/ That contain files with the same names but different compiler-dependent implementations. Then it is just a question of setting the PATHs right. I hate using C preprocessor stuff for this. I think the directory solution is nice because it forces you to concentrate all the compiler-dependent stuff into a few modules, which are distinct from the rest of the implementation. /Koen. -- Koen Claessen http://www.cs.chalmers.se/~koen phone:+46-31-772 5424 mailto:koen@cs.chalmers.se ----------------------------------------------------- Chalmers University of Technology, Gothenburg, Sweden
