Oh.  I've never seen that stated in my reading of the standard or rationale
(and couldn't find it stated in my on-line copy).

I did, however, find it also defined in <unistd.h>, <monetary.h>, <sys/msg.h>,
<sys/uio.h> (which I missed earlier), which invalidates my argument, supports
Mike's statement, and answers my question.

However, ssize_t is _not_ defined in <aio.h>, <mqueue.h>, <sys/socket.h>,
where it is also used, though each of these headers _may_ (not _shall_)
make ssize_t visible as defined in <sys/types.h> and/or <sys/uio.h>.  This
may be a bug in the standard.

		Cheers,

		Mark.
