Oh, I was thinking the other way: a compiler that says it's C11 but doesn't support _Atomic. I wrote my thoughts backwards, though.
If Gnulib code won't use _Atomic when compiled with GCC 4.9 (even though _Atomic would work), that doesn't sound like a big deal. For example, Debian 8 Jessie uses GCC 4.9 but long term support for Jessie ended in June and if Debian doesn't support it we don't need to worry about it.
