            Watchdog module interrupt mask, unmask and acknowledge differs 
            from other H8S/2674 modules. In order to support the function 
            cyg_interrupt_mask, cyg_interrupt_unmask and cyg_interrupt_acknowledge 
            for the watchdog module (also if you use it as a simple overflow timer), 
            additional code is necessary that is executet everytime one of 
            the functions above is called. If you don't need the module or if you 
            use the eCos H8S/2674 watchdog driver then you do not need this extra 
            code. This will save some time in ISR's and decrease code size a
