>Description:
According to

http://pubs.opengroup.org/onlinepubs/009695399/basedefs/netdb.h.html

and

http://pubs.opengroup.org/onlinepubs/009695399/functions/getaddrinfo.html

AI_ADDRCONFIG is a constant that shall be provided by netdb.h and
accepted by getaddrinfo(3).
But it is not provided by NetBSD-current. Due to this some software fails
to build on it. The same for AI_NUMERICHOST, AI_V4MAPPED and some others.

>How-To-Repeat:
man getaddrinfo

>Fix:
