Re: nmap 6.47 compile failure on AIX 7100-03

Kevin,

Commit r33675 ought to work around this weird hang. I'm not proud of it,
but I've drained too much of my life into the problem over the past week.
Now all of IPv4 works, but my setup here does not have any IPv6
connectivity. Also, some VPN oddness is making it so I can't be sure that
traceroute works (it's showing that everything is only 1 hop away, which is
incorrect). I'd appreciate any followup bug reports, which you can send to
the dev mailing list in a new thread.
