commit 7ae22829afb2b4ca531d1c00437d428f55d59341
Author: Ulrich Drepper <drepper@gmail.com>

    Restore _res correctly
    
    getaddrinfo works around the resolver functionality to avoid automatic
    IPv6 lookups.  The restoring didn't allow for the resolver to set
    additional bits in _res.

 * The RPC implementation in libc is obsoleted.  Old programs keep working
