First of all, in parse.c in function Parse() change things like this
(and this is for that last little fix mentioned):

  Parse_Frame ();

  Post_Media(Frame.Atmosphere);

#ifdef GlowPatch
  if (Frame.Objects == NULL && Frame.Glows == NULL)
  {
    Error ("No objects or glows in scene.");
  }
#else
  if (Frame.Objects == NULL)
  {
    Error ("No objects in scene.");
  }
#endif
  Stage = STAGE_CLEANUP_PARSE;

This makes it possible to render a scene with no objects, no lights but
only glows.
To allow parsing you should modify Parse_Frame() in parse.c like this
(at the end of the function):

#ifdef GlowPatch
  /*YS sept 18 2000 
     added this here too to allow 
    for a scene with only glow */
  CASE(GLOW_TOKEN)
    #ifdef UnofficialBlocking
        parseUnofficialFeature(60);
    #endif  
    {
    GLOW * NewGlow = Create_Glow();
    Parse_Glow(NewGlow);
    Add_Glow(NewGlow);
  }
  END_CASE
#endif

     OTHERWISE
       UNGET
       Object = Parse_Object();
       if (Object == NULL)
         Parse_Error_Str ("object or directive");
       Post_Process (Object, NULL);
       Link_To_Frame (Object);
     END_CASE
   END_EXPECT
  }
