foreign export doesn't deal with newtypes correctly
GHC does not accept foreign export dynamic where the result is not
Addr but a newtype for Addr. I think it should:
module M1 where
import Foreign
newtype FunPtr a = FunPtr Addr
foreign export dynamic f :: (Int -> Int) -> IO (FunPtr (Int -> Int))
Moreover, foreign export dynamic does not work with the NCG.
