  Log:
  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.
