I don't think so. I realized that in my first message I have written
"pragma Style_Checks ("s", Off)" which is incorrect in Ada.
I would want to turn off the declaration for function used just in
body.
So yes I have to use "-s", "s" would let it on because of options used
in compilation command line that make all style, warning etc as an
error.

It clearly works in Ada, it's just the examiner that reports this
error. And if I comment the pragma, the examiner succeeds.

Thanks for your advices.
