2549 was a leftover from an earlier version of the routine. Move
2550 several routines out to avoid deep nesting and indentation.
2551 (Inputs_Match): Add formal parameter Dep_Clause. Rename formal
2552 parameter Do_Checks to Post_Errors. Update the comment on usage.
2553 (Is_Matching_Input): Renamed to Input_Match. Add formal parameters

2636 the logic that generates a runtime check to determine the

2726 * s-tassta.adb (Abort_Dependents): Don't abort all dependents;
2727 just direct dependents. If this is actually an abort, each task

2730 time from Vulnerable_Complete_Master "for convenience" (i.e. to
2731 kill off tasks waiting at terminate alternatives), aborting
2732 indirect dependents is wrong, because it causes some unrelated
2733 tasks to get aborted.
