A comment in tcp_input() (in sys/netinet/tcp_input.c) reads:

 * Since we've covered the SYN-SENT and SYN-RECEIVED states above
 * we must be in a synchronized state.  RFC791 states (under RST
 * generation) that any unacceptable segment (an out-of-order SYN
 * qualifies) received in a synchronized state must elicit only an
 * empty acknowledgment segment ... and the connection remains in
 * the same state.

Of course, that's 793, not 791 (and "Reset" is spelled out in the RFC section header).
