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