- * fake library for ssh
- *
- * This file includes getaddrinfo(), freeaddrinfo() and gai_strerror().
- * These functions are defined in rfc2133.
- *
- * But these functions are not implemented correctly. The minimum subset
- * is implemented for ssh use only. For example, this routine assumes
- * that ai_family is AF_INET. Don't use it for another purpose.
