In Boost.Atomic 1.67 and later the <code class="literal"><span class="emphasis"><em>op</em></span>_and_test</code>
operations will return the opposite value (i.e. <code class="computeroutput"><span class="keyword">true</span></code>
if the result is non-zero). This was changed for consistency with other
operations in Boost.Atomic, as well as with conventions taken in the
C++ standard library. Users may prefer to postpone using these operations
until Boost 1.67 to avoid the need to update the code after the upgrade.
