Hi Thomas,

I don't mean to support glibc 2.1.3. It didn't properly support IPv6, and  
it if ships broken implementations of standards interfaces (IEEE Std  
1003.1-2001) such as getaddrinfo(), there isn't much an application can do.

This AI_ADDRCONFIG change fixes real-world issues and has been in Red  
Hat's packages for a long time.

Sorry.
