[PATCH] 2.4.16 won't compile without TCP/IP

[Tommi Virtanen <tv@xxxxxxxxxx>]

        Disabling CONFIG_INET makes 2.4.16 fail at compile due to
        include/net/tcp_ecn.h using macros INET_ECN_xmit and
        INET_ECN_xmit. They try to access the af_inet member of a
        union

#define INET_ECN_xmit(sk) do { (sk)->protinfo.af_inet.tos |= 2; } while (0)
#define INET_ECN_dontxmit(sk) do { (sk)->protinfo.af_inet.tos &= ~3; } while (0)

        but without CONFIG_INET, the union has no af_inet field.
        Here's a patch that disables the whole header if CONFIG_INET
        is not set. You may prefer some other approach; please just fix
        the symptoms :)

        And just to be sure, here's a minimal config that triggers the
        failure. Everything else is unset.
