Re: [boost] Enabling fast swap optimization for Boost types VC9 SP1.

Loïc Joly:

I was under the impression that with VC9 SP1, boost::shared_ptr would just be an alias to std::tr1::shared_ptr.

No, boost::shared_ptr is never an alias. You can use the Boost.TR1 wrapper library to get an std::tr1::shared_ptr that is either native (if the compiler provides one) or an alias of boost::shared_ptr.
