No, that's wrong. If you are writing certified code in which deactivated
code is not permitted, then it may not be feasible to add such checks, and
is certainly not desirable.

Incidentally, I can't begin to duplicate the assembly output you are
getting from GNAT, but probably that is because you are using an obsolete
version.
