I was unable to compile Ncat on Windows, but not because of these
errors (in fact, I never ran into them).  I've attached a patch
against your branch which contains the changes I made to get it
working (like compiling Nbase and Nsock).

This was mostly trial-and-error, so I'm sure it can be improved, but
it's a starting point.

On top of the changes in the patch, I needed to copy Nmap's
mswin32/lib to Ncat's mswin32 directory, because it wasn't there when
I checked it out.

I don't think I've forgotten anything, but if you have any questions
about what I did, feel free to ask.

And here's the proof:

C:\nmap-svn\ncat>mswin32\Debug\ncat
Ncat: You must specify a host to connect to.
Ncat: Try `--help' or man(1) ncat for more information, usage options and help.

Thanks,
Kris Katterjohn
