Problems with -S on Windows Re: Informal Nmap 3.94ALPHA1 Release

[kx <kxmail () gmail com>]

In both 3.93 and 3.94 ALPHA1 on Windows I could not get -S to work,
and always got the following error:

nmap -S 192.168.1.2 192.168.1.1 -d9
Failed to resolve/decode supposed IPv4 source address 192.168.1.2.
Note that if you are using IPv6, the -6 argument must come before -S
QUITTING!

While I am probably using the option incorrectly, I added a
gai_strerror call after getaddrinfo in resolve in tcpip.cc and got the
following:

Error code 10093: Either the application has not called WSAStartup, or
WSAStartup failed.

This is because win_init is called after we set all of our options.

Moving win_init prior to the while loop seems to fix this, and only
required adding a -e eth0 to the command line to get the -S option to
work.

Sorry no patch, but I am unsure as to what the preferred solution would be.

Cheers,
kx
