2511 was a leftover from an earlier version of the routine. Move
2512 several routines out to avoid deep nesting and indentation.
2513 (Inputs_Match): Add formal parameter Dep_Clause. Rename formal
2514 parameter Do_Checks to Post_Errors. Update the comment on usage.
2515 (Is_Matching_Input): Renamed to Input_Match. Add formal parameters
2516 Ref_Inputs and Do_Checks. Rename formal parameter Do_Checks
2517 to Post_Errors. Update the comment on usage. Account for the
2518 case where a self referential state may have a null input_list.

2545 2014-02-04 Robert Dewar <dewar@adacore.com>
2547 * exp_ch4.adb (Expand_N_Expression_With_Actions): Eliminate
2548 cases where Actions is a null list.
2549 * sinfo.ads (N_Expression_With_Actions): Actions can be

2551 in the final expanded tree.

2687 * s-taskin.ads: Minor comment fix.
2688 * s-tassta.adb (Abort_Dependents): Don't abort all dependents;
2689 just direct dependents. If this is actually an abort, each task
2690 will take care of aborting its dependents, so all dependents will
2691 get aborted, as before. However, when this is called the second
2692 time from Vulnerable_Complete_Master "for convenience" (i.e. to
2693 kill off tasks waiting at terminate alternatives), aborting
2694 indirect dependents is wrong, because it causes some unrelated
2695 tasks to get aborted.
