| Subject: | Net::Pcap 0.17 doesn't build on Win32 with WinPcap 4.1.x |
Follow-up to Bug ID: 53292, version 0.17 does not incorporate the provided patches and thus does not build on Windows (specifically attempted on Windows 7 x64, Strawberry Perl 5.16.1). The following patches consolidate the 4 patches from Bug ID: 53292 and provide 2 patches that when applied, allow Net::Pcap 0.17 to successfully build on Windows.
Please see:

for more details.
