Specifically, atomic builtins are not used when compiling for i386, which is MinGWs default target architecture (unless we specify a different -march). GCC will always encounter this problem when targeting i386. Thus the correct fix is to use fallback when GCC is targeting i386 — not when GCC is targeting MS Windows. So I am closing this PR. But Mark's fix must be corrected, because it does not really address the problem (which is i386, not MinGW)!
