   4 Subject: [PATCH] utils: nfsynproxy: fix build with musl libc
   5
   6 The musl libc exposes some struct tcphdr field only when _GNU_SOURCE is
   7 defined. Fix the following build failure:
   8
   9 nfsynproxy.c: In function ‘parse_packet’:
  10 nfsynproxy.c:34:9: error: ‘const struct tcphdr’ has no member named ‘syn’
  11   if (!th->syn || !th->ack)
  12          ^
  13 nfsynproxy.c:34:21: error: ‘const struct tcphdr’ has no member named ‘ack’
  14   if (!th->syn || !th->ack)
  15                      ^
  16 nfsynproxy.c:42:8: error: ‘const struct tcphdr’ has no member named ‘res2’
  17   if (th->res2 == 0x1)
  18         ^
  19 nfsynproxy.c:45:13: error: ‘const struct tcphdr’ has no member named ‘doff’
  20   length = th->doff * 4 - sizeof(*th);
  21              ^
