Interesting question. From a PRACTICAL point of view, I can't see spending
much time/effor on this. From a "legalistic" point of view, if you want to
claim to be a "conforming" compiler to the '85 Standard (with amendments),
then you do need to flag extensions. Personally, I would say that it is up to
those doing the work - as long as the "documentation" makes it clear which
you have decided.
