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