That's incorrect. 2015's XP targeting has the same level of C++11/etc. support as Vista+ targeting. (IIRC, the separate toolset is because a different Windows SDK is required.)

For example, I wrote a dedicated implementation of call_once() for XP, avoiding Vista's InitOnceExecuteOnce that is used otherwise.
