    Changes related to arithmetic types:
    
    * Renamed macros NUMERIC_FOO to ARITHMETIC_FOO to match C99-speak
    
    * ARITHMETIC_TYPEs now have a Real instance, otherwise they are quite useless.
      Note that this differs from the FFI spec, but the spec should very probably
      changed in this respect.
    
    * Some changes to fix the wrong assumption that CTime/CClock are integral types,
      C99 in fact guarantees only that they are arithmetic types. This has been
      accomplished by using
    
         realToInteger = round . realToFrac :: Real a => a -> Integer
    
      instead of fromIntegral for CTime/CClock. I'm not sure if we could do better,
      going via Double seems to be overkill, but I couldn't think of a better way.
      GHC could e.g. use RULES here. Improvements welcome.
