 In a jumble of messages from lots of parallel invocations of ghc I see
 this message:
 {{{
 Implicit import declaration:
     Warning: In the use of `catch'
              (imported from Prelude, but defined in System.IO.Error):
              Deprecated: "Please use the new exceptions variant,
 Control.Exception.catch"
 }}}
 That's nice, but what module did this message come from?
