Did you miss the rest of my reply?  I wasn't suggesting that would fix the
error, I was pointing out you've misunderstood how to use typename.

Obviously, because it's completely bogus.
I never suggested the *compiler* mistakes it for a namespace.   The syntax you
want is "typename T::A" and not "typename::T::A" - just look at the examples in
the standard.

This really isn't the right place for you to learn C++, but my last reply has a
link which might explain the new error you're getting. It's not a GCC bug.
