  * Make auto-generated *_paths.hs module warning-free.
  
  On newer GHCs using {-# OPTIONS_GHC -fffi #-} gives a warning which
  can lead to a compile failure when -Werror is activated.  We therefore
  emit this option if we know that the LANGUAGE pragma is supported 
  (ghc >= 6.6.1).

    M ./Distribution/Simple/Build/PathsModule.hs -2 +10
