It doesn't, the implication is the other way around.  But if you're
asking for "observable non-conformance" then there are lot more obvious
ways to observe it than by showing that GCC doesn't use (A), (B) or (C).

Maybe, but there's no implementation of (A) or (C) in GCC that would
make requiring (B) a burden.  So I think Paul Eggert's question has
been answered.
