// This is a convenience header to pull in the platform-specific headers
// that define at least:
//
//     struct addrinfo
//     struct sockaddr*
//     getaddrinfo()
//     freeaddrinfo()
//     AI_*
//     AF_*
//
// Prefer including this file instead of directly writing the #if / #else,
// since it avoids duplicating the platform-specific selections.
//
// Note that this header transitively includes windows.h on Windows, which
// pollutes the global namespace with thousands of macro definitions, so try to
// avoid including this in headers. Including windows.h can also add significant
// build overhead.
