Actually, they DO work, but the interface documentation is botched
beyond belief, and when it was reworked for SVID 3 (and SVR4), the
types were gotten utterly wrong.  Consequently I avoid the library
versions and use my own implementation with proper types, etc.

Some time ago, Gary Moss <Moss at BRL.MIL> published his implementation
of these functions; you might contact him for a copy.
