5335 was a leftover from an earlier version of the routine. Move
5336 several routines out to avoid deep nesting and indentation.
5337 (Inputs_Match): Add formal parameter Dep_Clause. Rename formal
5338 parameter Do_Checks to Post_Errors. Update the comment on usage.

5513 just direct dependents. If this is actually an abort, each task

5516 time from Vulnerable_Complete_Master "for convenience" (i.e. to
5517 kill off tasks waiting at terminate alternatives), aborting
5518 indirect dependents is wrong, because it causes some unrelated
