new compile problem on linux-2.4.27-pre4 and his solution

[M. Basto]

Hi this happens on pre4 and not happen on pre3

tcp_input.c: In function `tcp_rcv_space_adjust':
tcp_input.c:479: structure has no member named `sk_rcvbuf'
tcp_input.c:480: structure has no member named `sk_rcvbuf'
make[3]: *** [tcp_input.o] Error 1
make bzImage error !

find  . -exec grep "sk_rcvbuf" {} \; -print
results:
#define sk_rcvbuf rcvbuf
./include/net/sctp/compat.h
        newsk->sk_rcvbuf = oldsk->sk_rcvbuf;
./net/sctp/socket.c
        if (sk->sk_rcvbuf < SCTP_DEFAULT_MINWINDOW)
                asoc->rwnd = sk->sk_rcvbuf;
                     min_t(__u32, (asoc->base.sk->sk_rcvbuf >> 1),
asoc->pmtu)))
./net/sctp/associola.c
                        if (space > sk->sk_rcvbuf)
                                sk->sk_rcvbuf = space;
./net/ipv4/tcp_input.c

So #define sk_rcvbuf rcvbuf
and I feel free to do this and resolve the compile problem.
