2523 was a leftover from an earlier version of the routine. Move
2524 several routines out to avoid deep nesting and indentation.
2525 (Inputs_Match): Add formal parameter Dep_Clause. Rename formal
2526 parameter Do_Checks to Post_Errors. Update the comment on usage.
2527 (Is_Matching_Input): Renamed to Input_Match. Add formal parameters
2528 Ref_Inputs and Do_Checks. Rename formal parameter Do_Checks
2529 to Post_Errors. Update the comment on usage. Account for the
2530 case where a self referential state may have a null input_list.

2610 the logic that generates a runtime check to determine the
2611 controlled status of the object about to be allocated or

2614 (Find_Object): Detect

2699 * s-taskin.ads: Minor comment fix.
2700 * s-tassta.adb (Abort_Dependents): Don't abort all dependents;
2701 just direct dependents. If this is actually an abort, each task
2702 will take care of aborting its dependents, so all dependents will
2703 get aborted, as before. However, when this is called the second
2704 time from Vulnerable_Complete_Master "for convenience" (i.e. to
2705 kill off tasks waiting at terminate alternatives), aborting
2706 indirect dependents is wrong, because it causes some unrelated
2707 tasks to get aborted.
