  tun.c: In function ‘do_ifconfig_ipv4’:
  tun.c:1217:17: warning: variable ‘ifconfig_remote_netmask’ set but not
  used [-Wunused-but-set-variable]
     const char *ifconfig_remote_netmask = NULL;

  tun.c:1213:10: warning: unused variable ‘tun’ [-Wunused-variable]
     bool tun = is_tun_p2p(tt);

this function....it's an ifdef trap.
