* Re-exported IO.HandlePosn, i.e.,

         type HandlePosition = Integer
	 data HandlePosn = HandlePosn Handle HandlePosition

* Added hTell :: Handle -> HandlePosition
  (merely a wrapper for IO.hGetPosn )

* Added hSetBinaryMode :: Handle -> Bool -> IO Bool
  for dynamically changing the 'translation mode' of a Handle.
  This stuff is only useful on platforms that make a distinction
  between text and binary files (e.g., Win32)
