Nagios-plugins-snmp-0.6.0 solaris compile problem

Has anyone been able to compile nagios-plugins-snmp-0.6.0 plugins with Solaris 9?

Solaris 9

I get this error with make

nagios_common_snmp.c: In function get_options': nagios_common_snmp.c:565: error: storage size of 'long_options' isn't known nagios_common_snmp.c:565: error: storage size oflong_options’ isn’t known
make[2]: *** [nagios_common_snmp.o] Error 1
make[2]: Leaving directory /tmp/nagios-plugins-snmp/src' make[1]: *** [all-recursive] Error 1 make[1]: Leaving directory/tmp/nagios-plugins-snmp’
make: *** [all] Error 2

Has anyone seen this? I’m not a programmer but usually I can figure compile issues out. Stumped on this one.
