[Nagiosplug-devel] Nagios plugin options -4 and -6

I get a compilation error on Solaris 2.6 using the latest version of
netutils.c. Reverting back to netutils.c v1.7 works okay.

This is the error:
gcc -DHAVE_CONFIG_H -I. -I. -I. -I.. -I../lib     -g -O2 -c `test -f
'netutils.c' || echo './'`netutils.c
netutils.c: In function `is_addr':
netutils.c:329: `AF_INET6' undeclared (first use in this function)
netutils.c:329: (Each undeclared identifier is reported only once
netutils.c:329: for each function it appears in.)

Looks like it is trying to use IPv6 when configure couldn't pick it up

I get something similar in check_ping, but I haven't investigated much
