stock fm_user_spawn(id)
{
 if(!(1 <= id <= global_get(glb_maxClients)))
  return;
 
 if(!is_user_alive(id))
 {
  set_pev(id, pev_deadflag, DEAD_RESPAWNABLE);
  dllfunc(DLLFunc_Think, id);
 }
 else
  dllfunc(DLLFunc_Spawn, id);
}

I remember that setting the flag to DEAD_RESPAWNABLE and then use DLLFunc_Spawn didn't work properly, so DLLFunc_Think is just fine.
