I agree.  I'd prefer to know exactly what's going on in the atomic
code (rather than having the compiler take care of it for me).
Similarly, it's pretty rare to use GCC on anything but Linux and the
*BSDs as each proprietary UNIX vendor has their own compiler optimized
for their own architectures and operating systems.
