[Fwd: cvs commit: fptools/libraries/base/Foreign/C Types.hs fptools/libraries/base/System CPUTime.hsc Directory.hs Time.hsc fptools/libraries/base/System/Posix Types.hs fptools/libraries/base/include CTypes.h]

I've just commited a change to the fptools repository, proposing a minor change
in the FFI spec, see below. Comments welcome.

Cheers,

   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.
