I looked at that, and actually we use route_loop on non-Linux platforms,
but the struct returned by that function is

struct route_entry {
        struct addr     route_dst;      /* destination address */
        struct addr     route_gw;       /* gateway address */
};

It doesn't have the gateway bit, the "G" flag in netstat. It looks like
this bit is called RTF_GATEWAY.
