    ****************************************************************
    * RECOMMENDATION:  Apply the fix.                              *
    ****************************************************************
    The ODRLIB "server process" uses an Apache API to determine when
    a
    graceful restart is in process, but that API had changed between
    Apache 2.2 and Apache 2.4. While this would normally result in a
    compilation error, a fluke allowed the code to compile under
    Apache 2.4 but at runtime would never figure out a graceful
    restart was occurring.
