---------------CODE----------------------

#if LWIP_HAVE_LOOPIF
  if (strcmp(hostname,"localhost")==0) {
    addr->addr = INADDR_LOOPBACK;
    return ERR_OK;
  }
#endif /* LWIP_HAVE_LOOPIF */

  if (nodename != NULL) {
    /* service location specified, try to resolve */
    err = netconn_gethostbyname(nodename, &addr);
    if (err != ERR_OK) {
      return EAI_FAIL;
    }
  } else {
    /* service location specified, use loopback address */
    addr.addr = INADDR_LOOPBACK;
  }
-----------------------------------------

addr->addr = INADDR_LOOPBACK;

should be 

addr->addr = htonl(INADDR_LOOPBACK);
