// About us linking the system inet_pton and inet_ntop symbols:
// 1) These symbols are usually defined on POSIX systems
// 2) They are not defined on Windows versions earlier than Vista
// Defined in:
// ut_utils/src/sockaddr.cpp
// libutp/win32_inet_ntop.obj
//
// When we drop support for XP we can just #include <ws2tcpip.h>, and use the system functions
// For now, we will always use our functions on windows, on all builds
// The reason is: we would like the debug build to behave as much as the release build as possible
// It is much better to catch a problem in the debug build, than to link the system version
// in debug, and our version int he wild.
