| -- We do this because this unit used to have a body in earlier versions |
| -- of GNAT, and it causes various bootstrap path problems etc if we remove |
| -- a body, since we may pick up old unwanted bodies. |
| -- |
| -- Note: we use this standard Ada method of requiring a body rather |
| -- than the cleaner pragma No_Body because System.Exceptions is a compiler |
| -- unit, and older bootstrap compilers do not support pragma No_Body. This |
| -- type can be removed, and s-except.adb can be replaced by a source |
| -- containing just that pragma, when we decide to move to a 2008 compiler |
| -- as the minimal bootstrap compiler version. ??? |
