I think the answer is that it is possible for the implementation to
declare those interfaces by using another type known by the
implementation to be equivalent to ssize_t.  It probably is a bug in
the standard that the type itself is not required to be defined there,
but it is perhaps not a formal defect.  You might consider filing an
Aardvark about it.
