Building with this define requires this patch to capture-wpcap.c. Attached.

And I get this error with MingW:
  gtk/sctp_assoc_analyse.c:221: error: dereferencing pointer to incomplete type
  gtk/sctp_assoc_analyse.c:280: error: dereferencing pointer to incomplete type
....

  gtk/sctp_stat.c:370: error: invalid application of `sizeof' to incomplete type `sockaddr_in6'
...

<ws2tcpip.h> is needed for these definitions. Patch:
