17 -- This unit is not implemented in typical GNAT implementations that
18 -- lie on top of operating systems, because it is infeasible to implement
19 -- in such environments. The RM anticipates this situation (RM D.11(10)),
20 -- and permits an implementation to leave this unimplemented even if the
21 -- Real-Time Systems annex is fully supported.
23 -- If a target environment provides appropriate support for this package,
24 -- then the Unimplemented_Unit pragma should be removed from this spec,
25 -- and an appropriate body provided. The framework for such a body is
26 -- included in the distributed sources.
