> Summary: "netsnmp_extract_table_info" returns wrong size for integer 

Initial Comment:
Using 5.7.1 on opensuse 64-bit

We have a subagent that communicates with snmpd (AgentX protocol). The net-snmp \
libraries are linked into our application. We noticed that the function \
"netsnmp_extract_table_info" returns the wrong size (in val_len) for a integer index \
(32bit). On a 32-bit system, the size of integer index is 4 bytes. On a 64-bit system \
this returns 8 bytes. As a temporary measure, i have overridden this back to 4 bytes. \
 If you define a table, with a INTEGER as index; shouldn't \
"netsnmp_extract_table_info, val_len" return 4 instead of 8 ?

Internally net-snmp uses sizeof(long) to populate val_len. This returns 4 on 32-bit, \
and 8 on 64-bit.
