   --  No_List on entry, a new list is created.

   --  by pragma Initial_Condition. Spec_Or_Body denotes the spec or body of
   --  the package where the pragma appears. The check is inserted according
   --  to the following precedence rules:
   --    1) If the package has a body with a statement sequence, the check is
   --       inserted at the end of the statments.
   --    2) If the package has a body, the check is inserted at the end of the
   --       body declarations.
   --    3) The check is inserted at the end of the visible declarations.
