Well, I did some testing with DeckLink and it indeed is a mess to include 
stdatomic.h in C++ code. For some compiler/platform combinations it works, 
for others it does not. Maybe the cleanest solution is to simply use the 
C++11 std::atomic<int>.

Actually there was a thread about this:
https://ffmpeg.org/pipermail/ffmpeg-devel/2016-June/195902.html

And there is also a GCC bugzilla entry:
