What is the latest build for windows?

You are correct, but it's not the install script that does the building, the eqemu_server.pl that the install script runs is where all of that happens. The Perl script will download binaries for windows or compile them for Linux and gives you some management options if you run the script outside of the installer like database backup.

Edit: But it doesn't build the login server by default on Linux, I had to run cmake to set it to build the login server on my linux host.
