In Surge.nc, I was wiring Sounder as

implementation {
   components Main, SurgeM, TimerC, LedsC, NoLeds, Photo as Sensor, 
RandomLFSR,
     GenericCommPromiscuous as Comm, Bcast, MultiHopRouter as multihopM, 
QueuedSend;

#ifdef CHIRP_ENABLE
   Components Sounder;
#endif /* CHIRP_ENABLE */

....
}

Is this valid? Must all components be specify in one statement?

thanks,
