[PD-dev] compiler oopses compiling s_net.c on windoze

[Dan Wilcox]

Howdy Miller,

It seems those flags are defined in different headers depending on the Windows version:

https://docs.microsoft.com/en-us/windows/win32/api/ws2tcpip/nf-ws2tcpip-getaddrinfo#use-of-ai-flags-in-the-phints-parameter <https://docs.microsoft.com/en-us/windows/win32/api/ws2tcpip/nf-ws2tcpip-getaddrinfo#use-of-ai-flags-in-the-phints-parameter>

I think we just need PP a version check and relevant include at the top of s_net.c and/or s_net.h. Most people testing were using Windows 7+ which is probably why we didn't see this issue before.
