+<h4 class="subsection">8.1.2 Traditional GNU Objective-C Runtime API</h4>
+
+<p>The GNU Objective-C runtime used to provide a different API, which we
+call the &ldquo;traditional&rdquo; GNU Objective-C runtime API. Functions
+belonging to this API are easy to recognize because they use a
+different naming convention, such as <code>class_get_super_class()</code>
+(traditional API) instead of <code>class_getSuperclass()</code> (modern
+API). Software using this API includes the file
+<samp>objc/objc-api.h</samp> where it is declared.
+</p>
+<p>Starting with GCC 4.7.0, the traditional GNU runtime API is no longer
+available.
