Namespace not properly recognized

Hi Doxygen developers.

I have files like the following:

file.h:
namespace mynamespace {
  class MyClass {
   public:
    MyClass();
  }
}

file.cpp:
using namespace mynamespace;

/** @class MyClass <file.h>
 * My fancy class.
 */

/** Constructor. */
MyClass::MyClass()
{
}


This seems to be valid C++ and compiles properly (tested with GCC 4.1
and 4.3 on Fedora 8 and 9). However, if I try to run doxygen
(doxygen-1.5.5-2.fc8) on this it will complain:
Warning: Compound mynamespace::MyClass is not documented.

What I would expect is that it collects the "using namespace" clauses
and prepends these namespaces to the class names to test for matching
documentation. Can someone point me to the relevant lines in the code to
have a closer look or knows a solution already?

Regards from Aachen,
	Tim
