I am trying to compile my project with MTL (Matrix Template Library) and I am
having a lot of problems with a line in the xutility file.

Just including the headers and namespace for the library produces 45 errors.
I have found very little about this on Google, although it appears to be
specific to .NET. I imagine my settings are wrong? Or possibly a bug?

The calling code:

#include <iostream>
#include <mtl/mtl.h>
#include <mtl/matrix.h>
#include <mtl/utils.h>
#include <mtl/linalg_vec.h>
#include "CImg.h"

using namespace std;
using namespace mtl;
using namespace cimg_library;
....

The errors:

Most of the files cited are xutility and the library files, which I have no
control over, so I imagine there must be a workaround.

Any ideas?
