32 -- Simple casing functions
33
34 -- This package provides simple casing functions that do not require the
35 -- overhead of the full casing tables found in Ada.Characters.Handling.
36
37 -- Note: actual code is found in System.Case_Util, which is used internally
38 -- by the GNAT run time. Applications programs should always use this package
39 -- rather than using System.Case_Util directly.

44 pragma Pure;
45 pragma Elaborate_Body;
46 -- The elaborate body is because we have a dummy body to deal with
47 -- bootstrap path problems (we used to have a real body, and now we don't
48 -- need it any more, but the bootstrap requires that we have a dummy body,
49 -- since otherwise the old body gets picked up.
