Jeff Williams suggested a define in the source to clear up a similar problem
with bcopy:

We discussed some sort of refresh hackery to fix the warnings with GCC 3.x
I'm guessing that GCC is trying to inline these?  If so, what about
something like this in string.h? (refresh only, CVS is already fixed)

#if __GNUC__ >= 3
#define bcopy(s, d, n) memcpy(d, s, n)
#define bzero(s, n) memset(s, 0, n)
#else
void *	bcopy(const void *_a, void *_b, size_t _len);
void *	bzero(void *ptr, size_t _len);
#endif


Or can the prototypes be removed completely with GCC 3.x if they are
built-in?

#if __GNUC__ < 3
void *	bcopy(const void *_a, void *_b, size_t _len);
void *	bzero(void *ptr, size_t _len);
#endif

I don't have the time currently to test (I can't even finish my current
items...)
