Comment (by duncan):

 Ohh yes. Ok.

 I wonder if we should make hackage warn about -Werror in .cabal files
 since it makes them rather fragile and users who don't realise -Werror is
 there get quite confused. Alternatively (or in addition) perhaps we should
 have ghc print an error for the case that a there were warnings and
 they're being treated as errors. ie an extra error at the end to say that
 compilation is stopping due to preceding warnings and them being treated
 as errors because of the -Werror flag.
