Re: [uclibc-ng-devel] [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.
