+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.
