Description

All supported platforms of Dispatch can compile using C11 (or gnu11) language standard.

There is a caveat that GCC 4.8.5 claims to support C11 atomics but it doesn't. (It does not define _STDC_NO_ATOMICS_ while in fact the stdatomic.h header is missing.) Thankfully the Dispatch code is able to deal with the situation by using GCC-specific features, so it is not a problem.

I do not see any downsides to requiring C11 for Dispatch compilation.
