The macro's use bzero/bcopy... currently:

#define FD_COPY(f, t)   bcopy(f, t, sizeof(*(f))) 
#define FD_ZERO(p)      bzero(p, sizeof(*(p)))

Should probably be (in order to be more standard):

#define FD_COPY(f, t)   memcpy(t, f, sizeof(*(f))) 
#define FD_ZERO(p)      memset(p, 0, sizeof(*(p)))

Unless I'm mistaken?  (for more info on the FD_* look at 'man select')
