It's in the C++ standard, yes. I guess it will be in libstdc++ 3 which will
AFAIK come with gcc 3.

auto_ptr is relatively simple, at least compared to other STL classes. But
it's nevertheless a tricky thing I think...

You don't have to care about freeing the memory anymore, i.e. you'll have
less memory leaks. OTOH you have to be a bit careful how you use it (e.g.
copying it, passing it to some function etc).
I'd say for most things a careful "normal" memory handling isn't that much
