* Ensure, if at all possible, that AO_compare_and_swap_full() is

* though it actually blocks.
* Including this file will generate an error if AO_compare_and_swap_full()
* cannot be made available.
* This will be included from platform-specific atomic_ops files
* if appropriate, and if AO_REQUIRE_CAS is defined. It should not be
* included directly, especially since it affects the implementation
* of other atomic update primitives.
* The implementation assumes that only AO_store_XXX and AO_test_and_set_XXX
* variants are defined, and that AO_test_and_set_XXX is not used to
* operate on compare_and_swap locations.
