49 -- is used when a label is created by the expander without bothering
50 -- to insert an N_Implicit_Label_Declaration in the tree. It also takes
51 -- care of setting Reachable, since labels defined by the expander can
52 -- be assumed to be reachable.

55 -- This procedure is called with N being the node for a statement that is

58 -- if so generates an appropriate warning for unreachable code.
