I pinned the Cygwin/X "XWin Server" Start Menu item to the taskbar.
When I click that, I get "Cygwin/X Server 0:0" and "X applications menu on :0"
icons in the systray.
I set up to have a mintty window launched, near the end of ~/.startxwinrc,
copied from /etc/X11/xinit/startxwinrc, which now ends:

    if [ -x /usr/bin/x-terminal-emulator ] ; then
        /usr/bin/mintty - &
    fi

    exec /usr/bin/xwin-xdg-menu
fi

So that control still ends up in the XDG menu.
As mintty does not take normal XTerm options, it is run explicitly.
