I'll research a bit about your claims then; but I still doubt that the
STL implementations will cause general problems. Let's not forget we
were talking about containers and algorithms; not the mess that are
std::string, iostream, etc. It's not any different from writing a
bunch of template containers by hand.

I'm sorry, I think I wasn't too polite in my previous messages. I know
you guys made fabulous contribution to ODE, and know much more about
it than me. But I was expecting more solid arguments against STL. I
think I'll be much more convincing with numbers, so I'll try to put
together a (big) patch.
