4784 was a leftover from an earlier version of the routine. Move
4785 several routines out to avoid deep nesting and indentation.
4786 (Inputs_Match): Add formal parameter Dep_Clause. Rename formal
4787 parameter Do_Checks to Post_Errors. Update the comment on usage.

4961 * s-tassta.adb (Abort_Dependents): Don't abort all dependents;
4962 just direct dependents. If this is actually an abort, each task
4963 will take care of aborting its dependents, so all dependents will
4964 get aborted, as before. However, when this is called the second
4965 time from Vulnerable_Complete_Master "for convenience" (i.e. to
4966 kill off tasks waiting at terminate alternatives), aborting
4967 indirect dependents is wrong, because it causes some unrelated
4968 tasks to get aborted.
