I've never really liked this kind of code:  it always seemed to me
to be assuming something that, someday, on some weird machine, would
fail.  Surprise!
My rule is to always use an explicit reference to a defined constant:
	while ((*dst+= = *src++) != NUL);
This way, if my character set changes, I worry about this less.  By
the way, will your P**** machine take a constant like
	#define NUL	'\0'
and turn it into an eighth-high character?

By the way, your indentation above seems to me a tad peculiar.
char *strcpy(dst, src)
  char *dst;
  register char *src;
{
	register char *d = dst;

	while ((*d++ = *src++) != NUL);
	return(dst);
}
