Comment (by simonpj):

 Andrea, thank you!

 FWIW, it should not be hard to track down all warnings. They are all
 produced by
  * The renamer
  * The typechecker
  * The desguarer
 All three have monads, so you should be able to find all warning emissions
 by looking in `TcRnMonad` and `DsMonad` for the functions that spit out a
 warning.

 Simon
