Sounds to me like it says: "If you use an address clause to achieve an
overlay you are being a very bad, bad, programmer and should be made to stay
after programming school and write on the blackboard 'Thou Shalt Not
Overlay' 1000 times and learn that the compiler cannot save you if you do
stupid things like this. But if nobody is looking and the compiler doesn't
complain and it works anyway, the LRM won't have anything against this..."
I suppose it depends on your perspective about "rules". Is the Ada83 LRM of
the belief that anything not forbidden is mandatory? Or is the Ada83 LRM of
the belief that it is easier to get forgiveness than permission? I'd prefer
to view the paragraph you cite as the LRM choosing to protect itself by
declaring such use erroneous, but not stopping any compiler from giving you
exactly what you asked for.
