>Description:
The code below shows how explicit template instantations
fail when the name of the template starts with a
reference to the global namespace "::".

explicit-instantiation-absqual.cc:8: parse error before `;' token

Versions 2.95.3 and 3.1 20010617 show the same error.
>How-To-Repeat:
namespace N {
  template<class T>
  class A { };
}

// template class N::A<int>;   // this works (by itself)
template class ::N::A<int>;    // but this doesn't
