Since GCC 7.1 we print:
66475.cc:19:11: error: 'using Base = struct Foo<int>' is private within this
context
Bar<int>::Base x; // shouldn't compile, Base is private
^~~~
66475.cc:10:22: note: declared private here
using Base = Foo<T>; // the combination of this and the public export of a
type from Base below, causes this example to compile even though it shouldn't
^
