2539 was a leftover from an earlier version of the routine. Move
2540 several routines out to avoid deep nesting and indentation.
2541 (Inputs_Match): Add formal parameter Dep_Clause. Rename formal
2542 parameter Do_Checks to Post_Errors. Update the comment on usage.
2543 (Is_Matching_Input): Renamed to Input_Match. Add formal parameters

2626 the logic that generates a runtime check to determine the
2627 controlled status of the object about to be allocated or

2715 * s-taskin.ads: Minor comment fix.
2716 * s-tassta.adb (Abort_Dependents): Don't abort all dependents;
2717 just direct dependents. If this is actually an abort, each task

2719 get aborted, as before. However, when this is called the second
2720 time from Vulnerable_Complete_Master "for convenience" (i.e. to
2721 kill off tasks waiting at terminate alternatives), aborting
2722 indirect dependents is wrong, because it causes some unrelated
2723 tasks to get aborted.
