Stylesheet bug: funcprototype wrongly rendered

Hello,

version 1.65.1 of the stylesheets renders funcprototypes wrongly.

The example file is:

   <refentry>
     <refnamediv>
       <refname><function>system_starte_rakete()</function></refname>
       <refpurpose>Rückstoßgetriebene Marseroberung</refpurpose>
     </refnamediv>

     <refsynopsisdiv>
       <funcsynopsis>
         <funcprototype>
           <funcdef>void <function>system_starte_rakete</function></funcdef>
           <paramdef>
             <parameter>char* format</parameter>
             <parameter>long int schub</parameter>
           </paramdef>
         </funcprototype>
       </funcsynopsis>
     </refsynopsisdiv>

     <refsection>
       <title>Eine sehr lange Überschrift</title>
       <para>Hier kommt ein ganz normaler Satz.</para>
     </refsection>
   </refentry>

Processing this results in:

Synopsis

void system_starte_rakete(char* formatlong int schub);

char* formatchar* formatlong int schub long int schub ;

I think this is wrong. Isn't it?

Regards,

Oliver Fischer
