Links inside the HTML versions of man pages use <LINK> for links: <dt><span class="term"><a name="ALLOWHOSTS"></a>allow hosts (S) </span></dt><dd><p>Synonym for <link linkend="HOSTSALLOW">.</p></dd><dt> However, <LINK> is not meant for this usage (http://www.w3. org/TR/REC-html40/struct/links.html#edef-LINK): Although LINK has no content, it conveys relationship information that *may* be rendered by user agents in a variety of ways (e.g., a tool-bar with a drop-down menu of links). IMHO there is an <A HREF="HOSTSALLOW"> missing here.
This was a bug in the html generation. It has already been fixed in the CVS tree, we just need to fix the build environment an propagate the changes. Closing it as fixed.
