A windows version with _aligned_malloc >/ _aligned_free would also be possible. Making it work for MinGW would be nice. If there are other targets that don't support any of C11, POSIX-2001, or memalign then we can add a generic fallback later, but I'm not sure it's worth doing now. It might never be needed.
