Fully agreed.  __gnu_norm::vector<> is not a __gnu_debug::vector<>
even if both can be mapped to std::vector<> with 'using' statements.
We should not make changes to aid debugging tools, if they make actual
debugging harder.  I could support a scheme where std::__x::y implied
std::y for external tools that want to optionally hide such details.
