  * Figure out if hsc2hs is using gcc or ghc as it's C compiler
  and pass the appropriate flags on the basis of knowing that.
  This is a hack.
  What we should do longer term is make hsc2hs always use gcc as it's C compiler
  and have Cabal figure out the right flags to pass it, rather than using ghc
  to pass on the appropriate flags to gcc.
