Dear Sir,
I am writing to thank you for your letter and say
1 The test in configure fails :-
tssyd> more junk.c
#include <sys/types.h>
#include <netinet/in_systm.h>
#include <sys/socket.h>
#include <netinet/ip.h>
#include <netinet/in.h>
struct in6_addr tmp;
tssyd> gcc -o junk.o junk.c
In file included from junk.c:4:
/usr/include/netinet/ip.h:73: field `ip_src' has incomplete type
/usr/include/netinet/ip.h:73: field `ip_dst' has incomplete type
/usr/include/netinet/ip.h:158: field `ipt_addr' has incomplete type
tssyd>
2 netinet6/in6.h is included by netinet/in.h
grep -i -2 netinet6 /usr/include/netinet/in.h
/* INET6 stuff */
#define __KAME_NETINET_IN_H_INCLUDED_
#include <netinet6/in6.h>
#undef __KAME_NETINET_IN_H_INCLUDED_
Now this system is built (no kernel support) for IPv6 (but that is what
the system was built with the former snapshot - although there has been
a point upgrade of FreeBSD since then), so maybe that's breaking it ....
I think I am talking nonsense here ...
Sorry to be so useless.

'...No man is an island, entire of itself; every man is a piece of the
continent, a part of the main. If a clod be washed away by the sea,
Europe is the less, as well as if a promontory were, as well as if a
manor of thy friend's or of thine own were. Any man's death diminishes
me, because I am involved in mankind; and therefore never send to know
for whom the bell tolls; it tolls for thee...'
from Meditation 17, J Donne.
