[Bug c++/27227] New: [4.0/4.1/4.2 Regression] rejects valid code with some extern "C"

["pinskia at gcc dot gnu dot org" <gcc-bugzilla at gcc dot gnu dot org>]

Testcase:
namespace x {
extern "C" const int y;
};
using x::y;
extern "C" int const y=0;
-------

The testcase is orginally from Alex Rosenberg on the IRC channel, modified to
make it valid code so that the linkage specifications match.

This used to work before 4.0.0
