Yes, it's not support in VS 2012 and 2008 for Python 3.4 and older. New
C99 features are available in VS 2013,

Python 3.5+ requires VS 2015 anyway. Traditionally we tried to keep
backwards compatibility with older compiler versions. The new features
are tempting enough to deprecate compiler versions that have been
released more than five years ago.
