+              <code>--with-build-number=<var>number</var></code> to the
+              <code>configure</code> script, then it is also included

+              This version number is most useful for presenting to a human
+              administrator.  Use caution in interpreting a version number or
+              (especially) build number to indicate that a feature is or is not
+              supported.  Directly testing for a feature is more reliable.
