Re: mib2c.table_data.conf quastion/issue

It looks like the mib2c file was written assuming that MIBs follow the
SMIv2 practice of making INDEX objects not-accessible.

   Objects which are both specified in the INDEX clause of a conceptual
   row and also columnar objects of the same conceptual row are termed
   auxiliary objects.  The MAX-ACCESS clause for auxiliary objects is
   "not-accessible"
