- (bal) Reorder. Move all bsd-*, fake-*, next-*, and cygwin* stuff to
openbsd-compat/. And resolve all ./configure and Makefile.in issues assocated. Logic: * All OpenBSD functions should have the same filename as in the OpenBSD tree * All 'home brew' functions have bsd-* infront of them. * All 'not really implemented' functions have fake-* infront of them.

1/*
2 * fake library for ssh
3 *
4 * This file includes getaddrinfo(), freeaddrinfo() and gai_strerror().
5 * These funtions are defined in rfc2133.
6 *
7 * But these functions are not implemented correctly. The minimum subset
8 * is implemented for ssh use only. For exapmle, this routine assumes
9 * that ai_family is AF_INET. Don't use it for another purpose.
