 Well, I think we still didn't solve this:

   * Some flags are defined in DynFlags but not documented in the User's
 Guide. Should they be marked as hidden? Mail ghc-devs and find out.

 I don't think we git any replies about these flags and without that we
 cannot do better. Not sure if we should keep this ticket open as a
 reminder?
