And in
http://blogs.msdn.com/b/vcblog/archive/2014/06/11/c-11-14-feature-tables-for-visual-studio-14-ctp1.aspx
someone mentions that stdatomic.h doesn't exist in the 2014
version.  I can't find a reference that says anything in the 2015
changed related to that so I assume it didn't.

The only thing I could find is that the C library hasn't been
incorparated in the C++ standard.  But all the functions actually
exist in the C++ <atomic>.
