[freetds] DNS lookups not working with freetds

Tried current freetds and name lookups are not working at all with some older Linux systems for me. Everything that isn't an IP address returns -2 (EAI_NONAME)

The problem is triggered by setting ai_flags = AI_ADDRCONFIG in hints field of getaddrinfo and resolved by setting ai_flags = 0.

From what I've read in various man pages for getaddrinfo when set to 0

defaults are designed to be reasonable usually including AI_ADDRCONFIG anyway.

Would switching to default for ai_flags break anything for anyone?

thanks,
