Does Winpcap support the pcap_version[] array that normal libpcap
offers?  Here is how Nmap uses it in its configure.ac script:

  AC_MSG_CHECKING(if libpcap version is recent enough)
  AC_TRY_RUN([
#include <stdio.h>
extern char pcap_version[];
int main() {
  int major, minor;
  sscanf(pcap_version,"%d.%d", &major, &minor);
 [...]

Then again, testing for certain traits is often more reliable than
comparing version numbers.
