Yes: try...
You will see that the option attached to the command name appears in
Argument(1), the OS does the separation for you; nothing specific to
GNAT or Ada...
If you want an example, here is one:
  http://homepage.sunrise.ch/mysunrise/gdm/uza_html/unzipada__adb.htm

The commands
  unzipada/t test.zip
or
  unzipada /t test.zip
or
  unzipada -t test.zip
work as expected
