Comment (by duncan):

 Replying to [comment:3 tim]:
 > I take it back: {{{-fno-warn-orphans}}} seems to be silently ignored (if
 I pass it, I still see the orphan warning messages), so that should be
 fixed too.

 Hmm, that's interesting, it works for me in 6.8.2, both when specified on
 the ghc command line and in a pragma `{-# OPTIONS_GHC -fno-warn-orphans
 #-}`.
