And -- what version of what does contain those function there?

Probably the same using SVN. If somebody has a branch called 'memory_order_with_cool_functions',
and you have branch called 'tim', then it's not clear to me why you cannot merge
relevant commits from 'memory_order_with_cool_functions' to 'tim'.

Is this a real use case? If so, maybe you can point me at URLs and we'll check
in detail?
