3830 was a leftover from an earlier version of the routine. Move
3831 several routines out to avoid deep nesting and indentation.
3832 (Inputs_Match): Add formal parameter Dep_Clause. Rename formal
3833 parameter Do_Checks to Post_Errors. Update the comment on usage.

4007 * s-tassta.adb (Abort_Dependents): Don't abort all dependents;
4008 just direct dependents. If this is actually an abort, each task
4009 will take care of aborting its dependents, so all dependents will
4010 get aborted, as before. However, when this is called the second
4011 time from Vulnerable_Complete_Master "for convenience" (i.e. to
4012 kill off tasks waiting at terminate alternatives), aborting
4013 indirect dependents is wrong, because it causes some unrelated
4014 tasks to get aborted.

5594 * sem_elab.adb (Insert_Elab_Check): Remove complex

5760 the original one. the modification of the name must preserve
5761 the source location of the original, to prevent spurious errors
5762 when compiling with style checks if the declaration involves
5763 more than one entity.
