I think it would even work to compare sipx_network and sipx_node in one 
go. There is already code that copies them that way in 
ws_sockaddr_ws2u():

memcpy(&uipx->sipx_network,wsipx->sa_netnum,sizeof(uipx->sipx_network)+sizeof(uipx->sipx_node));

So we could do (compiles but not tested):

But your patch works too.
