    Hijack auto_ptr and replace it with a version that actually does
    what an auto_ptr normally does. If you use std::auto_ptr in your other code
    might either explode or work much better. The original crap created
    by Microsoft, called auto_ptr and bundled with MSVC6 is not standard compliant.
