There are a whole bunch of places where net-snmp uses a signed integer
for oid storage and integer comparisons.  We fixed some of them
locally (not that one, since we don't use net-snmp's ipAddrTable) but
didn't really think anyone else cared.

Especially if you look at the last one, it's fairly simple: make sure
that you are treating oid elements as unsigned.
