+  * fake library for ssh

+  * This file includes getnameinfo().
+  * These funtions are defined in rfc2133.
+  *
+  * But these functions are not implemented correctly. The minimum subset
+  * is implemented for ssh use only. For exapmle, this routine assumes
+  * that ai_family is AF_INET. Don't use it for another purpose.
+  * 
+  * In the case not using 'configure --enable-ipv6', this getnameinfo.c
+  * will be used if you have broken getnameinfo or no getnameinfo.
