They are undocumented (and therefore not defined in any header you & I
get).  They are unique to IBM's compiler.

Mario pointed out that VAC++ ver 3.0 has a documented fast semaphore now
(but I was unable to find it in the online manual).

I would suggest that anyone using either of these place them in wrapper
functions/macros so that the system sems can easily be replaced if you
switch to another compiler.
