Those have been accumulated over the years and I'd like to clean them up, remove the unused ones and fold as many of them as possible into a few generic implementations using either std::atomic, GCC atomic intrinsics (https://gcc.gnu.org/onlinedocs/gcc-10.1.0/gcc/_005f_005fatomic-Builtins.html) or GCC/intel sync intrinsics (https://gcc.gnu.org/onlinedocs/gcc-10.1.0/gcc/_005f_005fsync-Builtins.html).

How about a fall-back to Boost.Atomic?
