From 5e9a78c8a839381add6faa61e196e6dad9143163 Mon Sep 17 00:00:00 2001
From: Thomas Claveirole <thomas.claveirole@green-communications.fr>

Subject: [PATCH] include/netdb.h: Do not define IDN-related flags.
getaddrinfo() does not implement IDN encoding, and always fail when
provided an IDN flag (e.g., AI_IDN) with EAI_BADFLAGS. Some packages
(such as the VLC media player) check for AI_IDN before they use it;
providing an unimplemented AI_IDN in the libc makes these package
fail. As a result they make calls to getaddrinfo() with AI_IDN that
always fail while they could have made successful calls without AI_IDN
instead.
Thus, do not define IDN flags: it is better not to compile rather than
to compile a code that always fail.
