The new __libc_rpc_gethostbyname function calls gethostbyname2_r
with an AF_INET argument and is therefore not affected by the
RES_USE_INET6 flag.
Validated with the following test program, with and without
RES_OPTIONS=inet6, against a NFS server. (Link with -lrpcsvc.)
#include <rpc/clnt.h>
#include <rpcsvc/mount.h>
#include <stdio.h>
#include <string.h>

" %1$s HOST getrpcport\n"
" %1$s HOST callrpc\n"
" %1$s HOST clnt_create\n",
argv[0]);
}
static void
dump_exports (struct exportnode *exports)
{
while (exports != NULL)
{
