  * Fix the check for -XFooBar ghc-options flags to be more permissive
  Previously we rejected all such flags but that posed the problem that older
  versions of Cabal, like 1.1.6 did not understand new extensions so we
  could not actually follow the advice and use the extenion. So now we only
  warn about -X flags if they refer to old extensions that Cabal 1.1.6 knew
  about. If the .cabal file specifies cabal-version: >= 1.2 or similar
  (anything that excludes 1.1.6) then we warn about all -X flags.
