In src/apps/snmp/snmp_mib2_tcp.c, there is an incorrectly placed preprocessor
directive that cause an error if LWIP_HAVE_INT64 is not defined. The erroneous
code starts at line 598

Current:
598   &SYNC_NODE_NAME(tcp_HCInSegs).node.node,
599 #if LWIP_HAVE_INT64
600   &SYNC_NODE_NAME(tcp_HCOutSegs).node.node,
601   &SYNC_NODE_NAME(tcp_ConnectionTable).node.node,
602 #endif

Should be:
#if LWIP_HAVE_INT64
  &SYNC_NODE_NAME(tcp_HCInSegs).node.node,
  &SYNC_NODE_NAME(tcp_HCOutSegs).node.node,
#endif
  &SYNC_NODE_NAME(tcp_ConnectionTable).node.node,

tcp_HCInSegs and tcp_HCOutSegs are defined only if LWIP_HAVE_INT64 is true in
lines 522-525 of the same file, so we get an error that tcp_HCInSegs has not
been declared.
