SWIG vs C++ namespaces

[Dale Wilson-4]

Hi SWIG experts,

I've run into a problem using SWIG Version 1.3.35 to wrap some C++ code
for use by C#.  I've created a simple test that demonstrates the problem.

My C++ header file (Abc.h) contains:

  #ifndef ABC_H
  #define ABC_H
  #pragma warning (disable:4290) // VC: don't mutter about throw
specification
  namespace one
  {
    class Unique
    {
      Unique();
      ~Unique();
      void test()const;
    };
  }

  namespace two
  {
    class Unique
    {
      Unique();
      ~Unique();
      void test()const;
    };
  }
  #endif // ABC_H

and the AbcAdapter.swg file contains:
  %module AbcAdapter
  %{
  // Generated from AbcAdapter.swg
  #include "stdafx.h"
  #include "Abc.h"
  %}
  %include <stl.i>
  %include <std_common.i>
  %include "Abc.h"


When I run the command:

swig.exe -c++ -csharp -Fmicrosoft  AbcAdapter.swg

It says:

Abc.h(19): Error: 'Unique' is multiply defined in the generated module.
Abc.h(9): Error: Previous declaration of 'Unique'
Project : error PRJ0019: A tool returned an error code from "Creating
CSharp wrapper"
--------------------
So how can I convince SWIG to pay attention to the namespace when
checking for duplicate class declarations?

Thanks,

Dale
