-   --  These routines provide the necessary interfacing information to
-   --  correctly handle references in conditional structures (if/then/end-if,
-   --  or case/when/end-case). The issue here is that if a variable is only
-   --  set in some but not all branches of a conditional, then it is not
-   --  considered as being set by the conditional as a whole.
-
-   procedure Start_Unit;
-   --  Mark start of new unit to be analyzed, deals with fact that a call to
-   --  Rtsfind may cause new unit to be analyzed in middle of conditional.
-
-   procedure End_Unit;
-   --  Mark end of unit corresponding to previous call to Start_Unit
-
-   procedure Start_Conditional (If_Stmt : Boolean);
-   --  Mark start of a new conditional structure (an if-elsif-else-endif
-   --  or a case-when-end-case structure). If_Stmt is True for the IF
-   --  statement case, and False for the CASE statement case.
-
-   procedure Start_Branch (Loc : Source_Ptr);
-   --  Start processing of one branch of conditional previously marked by
-   --  a call to Start_Conditional (i.e. start of then/elsif/else statements
-   --  or set of statements after a when condition). The Loc value is the
-   --  source pointer to be used in warning messages concerning variables
-   --  not properly initialized in this branch. A branch is terminated by
-   --  either another Start_Branch or End_Conditional call.
-
-   procedure End_Conditional;
