test case

Hello,

Since my update to Doxygen 1.7.3, some anonymous namespaces are reported as being the “cpp” namespace.

The issue can be reproduced with the following cpp file:

===================================================
/**
 * \file
 */

#include "Foo.hpp"

namespace shq
{
  namespace
  {
    void private_function( )
    {
    }
  }
}
===================================================

If there is no “Foo.hpp”, then the function is properly detected as belonging to “shq::anonymous_namespace{Foo.cpp}”.
As soon as there is a “Foo.hpp” file (even empty), the function is detected as belonging to “namespace shq::cpp”.

The bug exists in Doxygen 1.7.3 but didn’t exist in 1.7.1.
