    PR modula2/115111 Incorrect line debugging locations at the end of the
WHILE loop

    This fix corrects the END token position used during the GotoOp at the
    bottom of the WHILE loop.  The fix is to pass the relative token position
    down to M2Quads.  This method should be replicated for the other loops
    END or UNTIL keywords and possibly the END statements for
    conditional statements.
