--- Comment #4 from Jason Merrill <jason at gcc dot gnu.org> ---
It's not clear to me that this is a bug.  As far as I can tell from the
standard, __func__ is an identifier, not a keyword, so the declaration of b
declares a function taking an A parameter named __FUNCTION__.  But there seems
to be no good reason to fight against existing practice on this, so I'm going
to revert the change.
