--  In Ada 95, the package Ada.Wide_Wide_Text_IO.Modular_IO is a subpackage
--  of Wide_Wide_Text_IO. In GNAT we make it a child package to avoid loading
--  the necessary code if Modular_IO is not instantiated. See the routine
--  Rtsfind.Check_Text_IO_Special_Unit for a description of how we patch up
--  the difference in semantics so that it is invisible to the Ada programmer.
