Cannot make SNMPv1-connect to agent with SNMPv3 disabled/deleted

[Frank.Fock____t-online.de]

Hi Bjoern,

If you do not need SNMPv3, then the easiest way
is to compile SNMP++, AGENT++, and your agent
with _NO_SNMPv3 defined. If you compile with
_SNMPv3 you must not remove the SNMPv3 MIBs
and the VACM initialization! 

Also, I recognized a "init_signals()" in your
code, may if you remove it, you will also get
a core dump when the agent crashes (yesterday's
problem ;-)

Hope this helps.

Best regards,
Frank
