commit 98f57a6c0e32bc6080a50e1cdd769b9ff78108bc
Author: William Cohen <wcohen@redhat.com>

    Remove unused functions causing errors in recent gcc
    
    The Fedora rawhide compiler is now stricter and will treat the
    warnings for unused functions as errors and stop the compile. This patch
    removes two unused functions in the code.
