That may be what you see as the important point in the message, but it
is by no means the only thing said in the message, let alone the only
implication of the message.

This discussion is about appearances as well as actuality.  Can you at
least agree that a reasonable person could reach my position?  That is,
maybe ACT has never actually broken using an older GCC to bootstrap
the Ada front end, but can you understand how I and others have come
to the conclusion that your policy was not to keep it working?

Please answer this question.

You responded to the pragma Unreferenced citation by stating that
pragma Unreferenced was not actually used in the compiler proper.
That is new information.  It was not in the message I cited.  Can you
understand how a reasonable person, working from the information in
that message, could have thought that the Ada maintainers planned to
introduce uses of pragma Unreferenced into the compiler proper?
