nfs-utils-1.1.2-tcpwrap-cleanup.patch:

--- NEW FILE nfs-utils-1.1.2-tcpwrap-cleanup.patch ---
Author: Steve Dickson <steved at redhat.com>
Date:   Sat Jan 31 06:17:18 2009 -0500

    General clean up. Removed unused routines. Reworked syslog
    message to (hopefully) make it more sensible. Move
    "#ifdef HAVE_LIBWRAP" around so nothing will be defined
    when tcp wrapper is not configured.
