it's misleading and does not attract the correct reviewers particularly
due to prominence in the commit/mail subject.

please change it to "Use GCC atomic builtins" which describes clearly
the actual change without ambiguity.  using "C11" implies the patch is
adding code that uses C11 stdatomic.h and it doesn't.
