Not surprising, since:

	1) I think the S5R4 Migration Guide is for the benefit of people
	   migrating code from earlier S5 releases, SunOS, BSD, Xenix,
	   etc. to S5R4, and most of those systems don't have "/proc";

	2) the SVID is for stuff AT&T decided to put into the SVID, and
	   apparently they decided not to put "/proc" into the SVID. 
	   (On the other hand, it *does* have "ptrace()", sigh....)

I suspect (and sincerely hope!) that "/proc" will be documented in the
actual S5R4 manual pages.
