+   --  in such environments. The RM anticipates this situation (RM D.11(10)),

+   --  Real-Time Systems annex is fully supported.
+
+   --  If a target environment provides appropriate support for this package,
+   --  then the Unimplemented_Unit pragma should be removed from this spec,
+   --  and an appropriate body provided. The framework for such a body is
+   --  included in the distributed sources.
