That would be great, thanks! With dtors for arbitrary C++ Standard
Library in their libc there's no way to build/use a third party
implementation such as stdcxx. Imagine one of the dtors doing
something to the class, e.g.:

     class length_error: runtime_error {   // MSVC 10 definition
         char* data;
     public:
         virtual ~length_error () { delete[] data; }
         // ...
     }
