38--  In Ada 95, the package Ada.Wide_Text_IO.Float_IO is a subpackage
39--  of Wide_Text_IO. In GNAT we make it a child package to avoid loading
40--  the necessary code if Float_IO is not instantiated. See the routine
41--  Rtsfind.Text_IO_Kludge for a description of how we patch up the
42--  difference in semantics so that it is invisible to the Ada programmer.
