@mgerhardy I would prefer my patch to be applied as in your patch the following to lines are duplicated:

+#include <winsock2.h>
+#include <ws2tcpip.h>

They are already there two lines up, so it would be cleaner to just merge the conditions:

-#ifdef _WIN64
+#if defined(_WIN64) || defined(__MINGW64_VERSION_MAJOR)
