This was an old library removed in r2811 and r2812, of which a few
traces remained.
I don't know the purpose of this in nbase_misc.c:
if(sd != 501) // Hack related to WinIP Raw Socket support
ioctlsocket (sd, FIONBIO, &one);
svn merge --ignore-ancestry svn://svn.insecure.org/nmap@26621 svn://svn.insecure.org/nmap-exp/luis/nmap-os6
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.
Some subset of these was causing the nmap project to always appear out
of date when beginning debugging. At any rate, they don't appear to be
necessary. Compare r25068.
