The problem is that the io code assumes int_type is indeed an integer
type, and does explicit casting to things like streamsize. This is not
correct, as a quick perusal of char_traits indicates.

I think Jack Reeves is correct on this point, and have modified the
appropriate code in question as per his patch.
