Ok, I built todays svn on AIX 5.2 with IBM xlc. This is the minimal
patch to get `./nmap -A other-host-on-lan' working.

net/if_arp.h can not be included without first including net/if.h, this
is a problem in libnetutil/netutil.cc and tcpip.cc.

-Wall isn't a portable compiler flag.

A number of macros in libdnet-stripped/include/dnet/icmp.h conflict with
macros in /usr/include/netinet/ip_icmp.h (errors with already defined
with a different definition). These macros do not appear to be used by
nmap.

IPV6_HOPLIMIT etc are defined on AIX 6, but not earlier.

Because we have a newer version of autoconf, it goes with the compiler
result instead of the preprocessor result when checking for headers, so
it says that we don't have net/route.h, and ends up building
route-none.c. including sys/socket.h for the header checks fixes it.

There are other problems with dependencies, -MM is a gcc flag, other
compilers have issues with it, I just typed `gmake' multiple times to
get around it rather than including a patch here.
