Thanks; in that case using atomic types and other C11 features is not 
possible at all for quite some time, and openmp support, while 
available, is restricted to version 3.1 of the spec (which should be 
just about enough - earlier versions do not have task support).

I actually have gcc 4.8 here (on debian testing, which will become 
debian 9 in a couple of weeks), even though the default version is 6.3, 
so I can test 4.8 compatibility locally.
