pragma Unreferenced is a new compiler-specific pragma, available in
gnat 3.15p and later.

It specifies that an object (usually a subprogram parameter) is
deliberatly unreferenced; the compiler warns you if you later
reference it. Helps with code readability.

You can safely ignore it with gnat 3.14p. But why not upgrade?
