redeclared without prototype") when compiling in

are code imported from outside sources.
... and on HP/UX, pass -Wl,+vnocompatwarnings as part of LIBS, no CC,

-- set compiler flags, yacc program.
-- define HAVE_UNIXWARE_SIGWAIT for one arg sigwait semantics.
-- provide for inclusion of netinet/in6.h for IPv6 support.
Don't bother searching for netinet6/in6.h, just unconditionally declare
it is needed on BSD/OS.
the CPP symbol it uses from *_HAVENETINET6* to *_NEEDNETINET6* to better
clarify what's going on with regard to the symbol.
Moved processing of --with-kame to before the in6addr_any check, since
it needs to set LIBS for the check to work. [related to RT #105, and
previous configure.in revision 1.108.]
in6_pkinfo check only needs AC_TRY_COMPILE, not AC_TRY_LINK.
library if it is available; therefore the --with-mit-pthreads
option is no longer needed. The --with-ptl2 option is now documented
as being experimental and applying to NetBSD only.
make v6 sockets, but we do not have struct in6_pktinfo.
Add a check in configure.in for struct in6_pktinfo.
Use the result of that check to define (if needed) in6_pktinfo in net.h.
This change makes us build on platforms that have SOME ipv6 structures
(like in6_addr, etc) but not enough to be useful to us.
Note: Before making an ipv6 socket the code should verify that ipv6
sockets can be made using isc_net_probeipv6(). It should also
check for v4 sockets using isc_net_probeipv4() to be consistant.
permitted to directly include netinet6/in6.h anymore. The RFCs and drafts
all say to include netinet/in.h and that will define the ipv6 goop if the
host supports it.
Rather than break (broken) OSs, I added a check for NetBSD in configure
that will force the definitions of
ISC_PLATFORM_HAVENETINET6IN6H
and LWRES_PLATFORM_HAVENETINET6IN6H
to be #undef.
This isn't really as clean as I'd like. I'd rather be hard and say an OS
that requires direct include of netinet6/in6.h is broken, and remove it
fully from our code.
