Squid-1.2beta7 - undeclared variable + link failure

The variable (intended to be a char *, I believe) snmp_agentinfo is used
in a debug statement but never declared.
Obviously fatal to the compilation.

I don't have any of the following enabled.

#SQUID_SNMP = -DSQUID_SNMP=1
#SQUID_MIB = mib.txt
#SQUID_SNMP_LIBS = -L../snmplib -lsnmp

Just supplying a declaration for it, allows the compile to proceed,
which brings us to the BIG failure:

I suspect that the snmp objects shouldn't be being included in the link,
or that their contents should have largely been #ifdef'ed out.

Wrapping the following source files with #if SQUID_SNMP yielded a
properly linked executable:
snmp_agent.c
snmp_config.c
snmp_vars.c

With those changes, squid-1.2beta7 appears to function (but since I was
typing this as I did it all, I don't claim that it really works
properly).
