+As of OpenSSH 4.0, configure will attempt to detect if your version
+and maintenance level of AIX has a working getaddrinfo, and will use it
+if found.  This will enable IPv6 support.  If for some reason configure
+gets it wrong, or if you want to build binaries to work on earlier MLs
+than the build host then you can add "-DBROKEN_GETADDRINFO" to CFLAGS
+to force the previous IPv4-only behaviour.
