From 224b7c7a816010fc0f781372051ec7c578af42a0 Mon Sep 17 00:00:00 2001 From: Gabriele Svelto Date: Sun, 11 Mar 2012 10:21:12 +0100 Subject: Check for AI_V4MAPPED and don't use it on FreeBSD Check if the constant is defined before using it. While the constant may be defined on FreeBSD, there's no support for the functionality and specifying the flag may cause errors.
