4333 was a leftover from an earlier version of the routine. Move
4334 several routines out to avoid deep nesting and indentation.
4335 (Inputs_Match): Add formal parameter Dep_Clause. Rename formal
4336 parameter Do_Checks to Post_Errors. Update the comment on usage.

4510 * s-tassta.adb (Abort_Dependents): Don't abort all dependents;
4511 just direct dependents. If this is actually an abort, each task
4512 will take care of aborting its dependents, so all dependents will
4513 get aborted, as before. However, when this is called the second
4514 time from Vulnerable_Complete_Master "for convenience" (i.e. to
4515 kill off tasks waiting at terminate alternatives), aborting
4516 indirect dependents is wrong, because it causes some unrelated
4517 tasks to get aborted.

6263 the original one. the modification of the name must preserve
6264 the source location of the original, to prevent spurious errors
6265 when compiling with style checks if the declaration involves
6266 more than one entity.
