+ gateway_ports = (strncmp(listen_address,"0.0.0.0",7) == 0) || options.gateway_ports;                                                    

this would violate the policy of the server.

if the sshd_config says: gatewayports==no, then the
socket should be bound to 127.0.0.1 only, regardless
of what the client wants.

	gateway_ports = options.gateway_ports &&
	    (strncmp(listen_address,"0.0.0.0",7) == 0);

would be correct.
