        Steve, as you're returning to level 0 of the stack there is no
        need to purge outstanding stack entries.

        The stack on PIC's is actually circular, so any particular stack
        entry can always be considered the zero'th entry.

        MPLAB is trying to be too helpful, and its simulation is innacurate.
