* [Bug c++/23586] New: [3.4/4.0/4.1 regression] Bad diagnostic for invalid namespace-name

For an invalid code snippet like
int i;
namespace N = i;
we issue the error message
bug.cc:2: error: expected namespace-name before ';' token
bug.cc:2: error: unknown namespace '<declaration error>'
with the not very helpful '<declaration error>'.
The situation for the code snippet
int i;
using namespace i;
is similar. Here we get the error message:
bug.cc:2: error: expected namespace-name before ';' token
bug.cc:2: error: '<type error>' is not a namespace
With the old parser we got
bug.cc:2: error: unknown namespace `i'
resp.
bug.cc:2: error: namespace `i' undeclared
so this qualifies as a diagnostic regression.
I'll post a patch soon.

Btw, the problem is related to PR13377.
The problem there is twofold: The compiler fails to report which
name is not a namespace-name (N2) and why (because it's ambiguous).
The patch would only fix the first problem; the second would
still remain.
