The comment in struct_ip.h explains the reasoning for this. The AIX C library
uses #defines that change the names of members of struct ip, and conflict with
some existing code. (Notably struct ip_hdr in libdnet and IPv4Header::h in
libnetutil.) We can still use the AIX files if we include <netinet/ip.h> after
this other code has been preprocessed. That's hard to enforce when
<netinet/ip.h> is included from another header file; this new file allows
including it always late, and only where needed.

This is the IPv6 OS detection branch. "nmap -6 -O" works now, though at
this point it only prints fingerprints and not OS guesses, because we
need to collect more submissions.
properly so our signal handing code actually activates. But our signal
handling code was a bit questionable in many respects, so I removed most
of it under the theory that it hasn't been working for years and nobody
seemed to notice/care, so we presumably don't really need it. And if we
do decide to add it again, we basically will need to do it over because
we now want to do it safely from a reentrancy perspective. In particular,
I removed sigdie() and reaper(). We still have a few signal() calls. In
particular, we ignore SIGPIPE and we set SIGINT, SIGTERM, SIGHUP, and
SIGSEGV to the defaults (SIG_DFL) explicitly. Thanks to Ithilgore, Luis,
and Solar Designer in particular for fidning or commenting on the issue.
a layer 4 protocol used mostly for telephony related applications.
This brings the following new features:
o SCTP INIT chunk port scan (-sY): open ports return an INIT-ACK
chunk, closed ones an ABORT chunk. This is the SCTP equivalent
of a TCP SYN stealth scan.
o SCTP COOKIE-ECHO chunk port scan (-sZ): open ports are silent,
closed ports return an ABORT chunk.
o SCTP INIT chunk ping probes (-PY): host discovery using SCTP
INIT chunk packets.
o SCTP-specific IP protocol scan (-sO -p sctp).
o SCTP-specific traceroute support (--traceroute).
o The ability to use the deprecated Adler32 algorithm as specified
in RFC 2960 instead of CRC32C from RFC 4960 (--adler32).
o 42 well-known SCTP ports were added to the nmap-services file.

exhaustive testing of 90 different probes, this one emerged as the
best four-probe combination, finding 14% more Internet hosts than
the previous default, -PE -PA80. The default for nonroot users is
-PS80,443, replacing the previous default of -PS80. In addition,
ping probes are now sent in order of effectiveness (-PE first) so
that less likely probes may not have to be sent.
