/*
 * This file is for FreeBSD-2.2 and early 3.0 that have a 4.9.4-P1 derived
 * resolver in the libc.  It provides aliases for functions that have moved
 * when 4.9.5-P1 is imported in 3.0.
 *
 * I'll save everybody the trouble and say it now:  *THIS IS A HACK*!
 *
 * Yes, many of these are private functions to the resolver, but some are
 * needed as there is no other way to provide the functionality and they've
 * turned up all over the place. :-(
