The advantage of the GCC built-ins is that they have easy-to-find documentation. Our wrapper macros are in the same file as the legacy atomics that no longer should be used. They are also not easy to use correctly (e.g., there is no support for access to single bytes, but the code will still compile on some architectures). The GCC built-ins have other problems, of course. For example, one might accidentally introduce a dependency on libatomic (leading to a link failure later). But I think these issues are less severe.
