| 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. | |

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. | |

| 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. | |
