 * so that there wouldn't be conflicts with the view table that's already
 * in the same area of the tree.
 *
 * Revision 1.10  2001/12/17 21:48:53  meister
 * Add missimg 4 objects from rfc2571

 * Revision 1.6  2001/11/15 21:53:50  josh
 * populate the proxy table a little
 *
 * Revision 1.5  2001/11/12 22:54:08  meister
 * Changed some DYNCFG_FUNCPTR's to DYNCFG_EXTERN_FUNCPTR's
 *
 * Revision 1.4  2001/11/08 22:18:37  meister

 * Revision 1.1.2.6  2001/10/16 20:52:11  meister
 * fix that snmpdLog message (initSmpV3Component) typo
 *
 * Revision 1.1.2.5  2001/10/16 20:07:22  josh
