Hmm, I think I meant

struct unit_order {
   enum orders_type type;
   union {
     enum unit_orders order;
     enum unit_activity activity;
     enum unit_actions action;
     enum diplomat_actions diplomat;
   } order;
   enum direction8 dir;
}

Is this also illegal?  It does have a name now.

If the type doesn't need to be associated with the union, how do you 
tell which type the union is?  How do you know whether a 0 is the first 
order or the first activity?
