[Haskell-cafe] Implementing Mathematica

Yes, I think it's a bug.  GHC should really compare the flags used last time with the flags used this time, and recompile if they have changed.  If enough people yell about it, we'll probably fix it!  Meanwhile opening a Trac bug report (or perhpas feature request) would be a good start.
