 <sect>Differences to the ISO standard<p>
 
+Apart from the things listed below, the compiler does support additional
+keywords, has several functions in the standard headers with names outside the
+reserved namespace and a few syntax extensions. All these can be disabled with
+the <tt><ref id="option--standard" name="--standard"></tt> command line
+option. Its use for maximum standards compatibility is advised.
+
 Here is a list of differences between the language, the compiler accepts,
 and the one defined by the ISO standard:
 
 <itemize>
 
-<item> The compiler allows unnamed parameters in parameter lists. The
-       compiler will not issue warnings about unused parameters that don't
-       have a name. This feature can be disabled with the <tt><ref
-        id="option--standard" name="--standard"></tt> command line option.
-       <p>
-<item> The compiler has some additional keywords:
-       <p>
-       <itemize>
-       <item><tt/asm/
-       <item><tt/__asm__/
-       <item><tt/fastcall/
-       <item><tt/__fastcall__/
-       <item><tt/__AX__/
-       <item><tt/__EAX__/
-       <item><tt/__func__/
-       <item><tt/__attribute__/
-       </itemize>
-       <p>
-       The keywords without the underlines can be disabled with the
-        <tt><ref id="option--standard" name="--standard"></tt> command line
-        option.
-       <p>
 <item> The datatypes "float" and "double" are not available.
        <p>
-<item> The compiler does not support bit fields.
-       <p>
 <item>         C Functions may not return structs (or unions), and structs may not
         be passed as parameters by value. However, struct assignment *is*
        possible.
