HP-UX compiles - redux...

[Rick Jones <rick.jones2 () hp com>]

since i botched the previous email...

seeing the ocmpile issue with HP-UX 11.11, I went ahead and downloaded the 
"current" versions for libpcap and tcpdump.  there were some rather simplistic 
errors that needed to be fixed to get pcap-dlpi.c to compile (HP ANSI C, HP-UX 
11.11, no TOUR installed) with the following warnings:

tcpdump-current went pretty wel until print-tcp.c:

*** Error exit code 1

which appears to have something to do with ipv6 stuff:

        } else if (IP_V(ip) == 6) {
                ip6 = (struct ip6_hdr *)ip;
                MD5_Update(&ctx, (char *)&ip6->ip6_src, sizeof(ip6->ip6_src));
                MD5_Update(&ctx, (char *)&ip6->ip6_dst, sizeof(ip6->ip6_dst));
                len32 = htonl(ntohs(ip6->ip6_plen));

now, there is an ip6_hdr in ip6.h.  However, the inclusion of ip6.h is 
conditional on INET6:

#ifdef INET6
#include "ip6.h"
#endif

but none of that IPv6 stuff where the error hits is conditional on INET6. 
Without a TOUR installed, HP-UX 11.11 knows little to nothing about IPv6.

I'm not quite sure what to do to fix that code - if I should make it ifdef INET6 
and return -1 as if it was an unknown IP version, or what.
