   procedure Analyze_Label_Entity (E : Entity_Id);
   --  This procedure performs direct analysis of the label entity E. It
   --  is used when a label is created by the expander without bothering
   --  to insert an N_Implicit_Label_Declaration in the tree. It also takes
   --  care of setting Reachable, since labels defined by the expander can
   --  be assumed to be reachable.

   procedure Check_Unreachable_Code (N : Node_Id);
   --  This procedure is called with N being the node for a statement that is
   --  an unconditional transfer of control or an apparent infinite loop. It
   --  checks to see if the statement is followed by some other statement, and
   --  if so generates an appropriate warning for unreachable code.
