Run 'mkzsh -A -D -P' from a bash shell and it will create zsh.bat in the
root dir and create a desktop icon as well as a Cygwin menu item.  It's a
very simply bat file, like cygwin.bat itself.

I guess I don't understand how you are starting the shell, really.  All
you need to do is change cygwin.bat to run 'zsh -l -i' instead of 'bash
--login' and it will run as a login shell.  /zsh.bat is simply a
convenient bat file which does this.  It seems like overkill to run a
cygwin shell wrapper which just does an exec of another shell, but to
each their own.  If it works for you, so much the better.
