Summary: check_snmp not processing strings

Initial Comment:
When I upgraded the software to Nagios 1.1 from 
Netsaint 7, the check_snmp plugin stopped working for 
any strings.
I have included the output below from one of the string 
checks.

[nagios at w2linux libexec]$ ./check_snmp -H w3linux -o 
system.sysName.0 -C public
SNMP OK - w3linux
[nagios at w2linux libexec]$ ./check_snmp -H w3linux -o 
system.sysName.0 -C public -s w3linux
SNMP CRITICAL - *w3linux*

As can be seen without the -s option the plugin come 
back with an ok status,  when I add the -s it always 
comes back critical even though is is an exact match.  
Enclosing string variable in single and double quotes 
yields the same invalid output.

Plugins are from the 1.3.0 build.

Sorry for the delay. Fixed in HEAD. 

Now the output of 
./check_snmp -H 127.0.0.1 -o sysServices.0 -C public
SNMP OK - 79

Can be used to match properly
./check_snmp -H 127.0.0.1 -o sysServices.0 -C public -s 79
SNMP OK - 79

Found a workaround for the problem, added the -OQ 
parameter to the end of the command line which removes the 
type designation i.e STRING: from the return.  Program is now 
processing string  correctley.  Output below.

/* create the command line to execute */
	asprintf (&command_line, "%s -m %s -v %s %s %
s:%s %s -OQ",
	          PATH_TO_SNMPGET, miblist, proto, authpriv, 
server_address, port, oid);
	if (verbose)
		printf ("%s\n", command_line);

Correct output:
[nagios at w2linux plugins]$ ./check_snmp -H w3linux -C public -
o system.sysName.0 -s w3linux
SNMP OK - w3linux

Put invalid string and it compared correctly.

[nagios at w2linux plugins]$ ./check_snmp -H w3linux -C public -
o system.sysName.0 -s w1linux
SNMP CRITICAL - *w3linux*
