Yes, note the emphasis on "linker switch". If you omit -largs, the compile
and link will silently ignore the -mwindows option (if my memory serves).

FYI, note that if you have any Put_Line() etc. calls to the console window,
either from debug code or by design, with the -mwindows option used, your
application will exit (I observed the application returning status code 3
when this happens).  So you'll want to disable those, if they are present ;-)
