+  <li>The <code>-Wparentheses</code> option now works for C++ as it
+  does for C.  It warns if parentheses are omitted when operators with
+  confusing precedence are nested.  It warns about ambiguous else
+  statements.  Since <code>-Wparentheses</code> is enabled by
+  <code>-Wall</code>, this may cause additional warnings with existing
+  C++ code which uses <code>-Wall</code>.  The new warnings may be
+  disabled by using <code>-Wall -Wno-parentheses</code>.</li>
