RE: GHCI Can't Find Module But GHC Can

I think the problem is that GHCi doesn't respect #ifdef conditional compilation. The HaXml package has modules with stuff like

#if defined(__HBC__) import IOMisc #endif

which seems to confuse the interpreter (but not the compiler). I've also seen reports that recent versions of GHC don't grok lines like

#if __GLASGOW_HASKELL__ <= 210

I wasn't aware of any bugs in that area, can anyone provide some sample code? (and I'm surprised, because GHCi just runs cpp in the same way as GHC). Cheers, Simon
