  * failWith: generate proper IOExceptions
  I cheated a little by mapping first to an errno, using the existing
  Foreign.C.Error.errnoToIOError, and finally adding the real error
  message from Win32.  To do this properly we should provide a
  Win32-specific version of errnoToIOError.

    M ./System/Win32/Types.hs -1 +14
