--- Comment #3 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
ICC rejects this with:
<source>(7): error: class template and template parameter may not have the =
same
name
  template < class A > struct N::A=20
                                 ^

When struct A is not in a namespace GCC, clang and MSVC all reject it with a
similar message. I suspect ICC gets this right really. That is it should be
rejected due to the name being the same.

In fact if we did:
namespace N=20
{
template < class A > struct A=20
{
};
}

GCC, clang and MSVC reject it too.=
