Better still:

#ifdef _FUNCTION_PROTOTYPES
#define PROTO(x) x
#else
#define PROTO(x)
#endif

extern void WcWidgetCreation PROTO((Widget root));
extern void WcWidgetCompaction PROTO((Widget leaves));
extern void WcWidgetDestruction PROTO((Widget branches));
extern void WcWidgetDemolition PROTO((Widget knots, Widget tegdiw, ...));
extern void WcWidgetEmulation PROTO((Widget worms));
