--  In Ada 95, the package Ada.Wide_Text_IO.Float_IO is a subpackage of
--  Wide_Text_IO. In GNAT we make it a child package to avoid loading
--  the necessary code if Float_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.
