Even if, wrong list. Go to the standard mailing lists. Also it's already
approved, so you're way too late.

You can use boost::shared_ptr prior to C++11.

It's not the hard:

#if __cplusplus <= 199711L
std::auto_ptr<foo> thiny;
std::shared_ptr<foo> thingy;

Then do not use C++17, simple as that. If you want full C++98
compatibility, use C++98.
