OK, I'm all for that.  I've had one other vote in favour of consistency
with g++.

Are you saying that, within the same function, __func__ and
__FUNCTION__ should be distinct?  I'm not persuaded.  I'm guessing
that the reason the standard specified the uniqueness criterion was so
that you could easily compare functions based on __func__ (quite why
you might want to do this isn't so clear to me).  If the pointers are
the same, then you unambiguously have the same function.

Do you find this reasoning persuasive?  I'm concerned about having the
three distinct for the same function; having them the same seems
better to me on first thoughts.

If I produced a patch to do one or the other, would you accept it for
3.1?
