Ticket 47615 - Failed to compile the DS 389 1.3.2.3 version against Berkeley DB 4.2 version
    
    Bug Description:  libdb 4.2 does not support the db->compact feature, which causes
                      build failures.  The compact feature was only added to libdb 4.4
    
    Fix Description:  Use preprocessor commands to ioslate the compact code.
