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