SPECIALISE pragma rejected; regression

Compiling this module:

module Q where

{-# SPECIALIZE f :: (Bool -> Bool) -> Int #-}
f :: (a -> Bool) -> Int
f = undefined 

fails with:

$ ghc -c Q.hs

Q.hs:3:1:
    Discarding pragma for non-overloaded function `f'
    In the SPECIALISE pragma
      {-# SPECIALIZE f :: (Bool -> Bool) -> Int #-}

This is causing build failures for Munkres, bitarray and bitmap.
