  * use forward-compatible Foreign.C.Types imports

  Previously, the hierarchy generator used #if in an attempt to choose between
  two choices for an import line. The one choice gives warnings on old GHC's; the
  other gives warnings on new GHC's. However, the symbol used in the #if isn't
  defined by gtk2hs' custom build system, so one of the two choices was the
  defacto code. Until this patch, the defacto code was the one that produced
  warnings on new GHC's.
  
  It should be possible to revise the build system to define this symbol, but it
  is becoming less and less likely I will have the energy to work out how to do
  this correctly. Instead this patch makes the choice to prefer the import that
  compiles cleanly on new GHC's, and let old GHC's print warnings.
