4305 was a leftover from an earlier version of the routine. Move
4306 several routines out to avoid deep nesting and indentation.
4307 (Inputs_Match): Add formal parameter Dep_Clause. Rename formal
4308 parameter Do_Checks to Post_Errors. Update the comment on usage.

4483 just direct dependents. If this is actually an abort, each task

4486 time from Vulnerable_Complete_Master "for convenience" (i.e. to
4487 kill off tasks waiting at terminate alternatives), aborting
4488 indirect dependents is wrong, because it causes some unrelated
