[Bug c++/28513] New: QOI: Diagnostic missing since 3.3.x when naming rule is violated

class foo {
public:
  typedef int bar;
};

class baz {
public:
  foo::bar foo;
};

With G++ 3.3.6, this errors out with this diagnostic:
$ g++-3.3 -pedantic -Wall -Wcast-align -Wwrite-strings -Wswitch-default
-Wcast-qual -Wunused-variable -Wredundant-decls -Wctor-dtor-privacy
-Wnon-virtual-dtor -Wreorder -Wold-style-cast -Woverloaded-virtual
-fstrict-aliasing -c foo.cc
foo.cc:8: error: declaration of `int baz::foo'
foo.cc:1: error: changes meaning of `foo' from `class foo'

With G++ 3.4, 4.0, 4.1 and 4.2 (current CVS), no diagnostic is issued.
A diagnostic is not strictly required by the standard (§3.3.6,
basic.scope.class), but would be very useful.

Regards,
Roger
