+<p><b>BOOST_NO_RTTI</b><span class="RenoBR">&nbsp;</span><br/><b>BOOST_NO_TYPEID</b> (both defined automatically by boost/config.hpp)</p>
 <p>The first macro prevents Boost Exception from using dynamic_cast and dynamic typeid. If the second macro is also defined, Boost Exception does not use static typeid either. There are no observable degrading effects on the library functionality, except for the following:</p>
 <blockquote><p>By default, the <span class="RenoLink"><a href="get_error_info.html">get_error_info</a></span> function template can be called with any exception type. If BOOST_NO_RTTI is defined, <span class="RenoLink"><a href="get_error_info.html">get_error_info</a></span> can be used only with objects of type boost::<span class="RenoLink"><a href="exception.html">exception</a></span>.</p></blockquote>
 <h4>Note:</h4>
 <p>The library needs RTTI functionality. Disabling the language RTTI support enables an internal RTTI system, which may have more or less overhead depending on the platform.</p>

Defining BOOST_EXCEPTION_DISABLE disables this integration.</p>
 <p>Note that on some non-conformant compilers, for example MSVC 7.0 and older, as well as BCC, BOOST_EXCEPTION_DISABLE is implicitly defined in <span class="RenoLink"><a href="boost_throw_exception_hpp.html">boost/throw_exception.hpp</a></span>.</p>
-<p><b>BOOST_NO_EXCEPTIONS</b></p>
+<p><b>BOOST_NO_EXCEPTIONS</b> (defined automatically by boost/config.hpp)</p>
 <p>This macro disables exception handling in Boost, forwarding all exceptions to a user-defined non-template version of boost::<span class="RenoLink"><a href="throw_exception.html">throw_exception</a></span>. However, unless BOOST_EXCEPTION_DISABLE is also defined, users can still examine the exception object for any data added at the point of the throw, or use boost::<span class="RenoLink"><a href="diagnostic_information.html">diagnostic_information</a></span> (of course under BOOST_NO_EXCEPTIONS, the user-defined boost::throw_exception is not allowed to return to the caller.)</p>
-<p><b>BOOST_THROW_EXCEPTION_CURRENT_FUNCTION</b></p>
-<p>The <span class="RenoLink"><a href="BOOST_THROW_EXCEPTION.html">BOOST_THROW_EXCEPTION</a></span> macro uses BOOST_THROW_EXCEPTION_CURRENT_FUNCTION to record the name of the current function in the exception object. Unless overridden by the user, BOOST_THROW_EXCEPTION_CURRENT_FUNCTION expands to BOOST_CURRENT_FUNCTION.</p>
