As a side note:
CGI applications are actually non-GUI applications. Which also means they can
run on for example a Linux server that doesn't have a GUI running or even
installed. So including Forms unit or any GUI units for that matter is going
to causes that CGI application to fail or report errors on startup anyway
because they cannot find the DISPLAY environment variable or open a
connection to the running X11 server. I have first hand experience with this
and had to rework the core tiOPF framework units to be truly non-gui, at
which point my CGI apps and console based unit test suite started working
correctly.
Windows users never detect this problem, because you don't get Windows severs
without a GUI (though I believe Microsoft is working on such a Server release
now).
As far as I know, Windows server 2008 is supposed to be able to work without
GUI.
