Cabal already adds -D__HUGS__ when building for Hugs, __HUGS_VERSION__
isn't used, and the SIZEOF's aren't universally valid. For GHC,
the package gets them from MachDeps.h (an undocumented interface).
Doing it portably probably requires autoconfery.
Apart from that, the main in Setup.lhs could just be defaultMain.
