-- The purpose of this body is simply to ensure that the two with'ed units
-- are properly included in the link. They are not with'ed from the spec
-- of System.Standard_Library, since this would cause order of elaboration
-- problems (Elaborate_Body would have the same problem).

-- direct calls to Ada.Exceptions are generated by gigi (for example,
-- by calling __gnat_raise_constraint_error directly).
