Agreed, yes, this sort of information would be very useful, although it
might make sense to go a little bit further, to the item of specifying if
a function can be used to modify the data, maybe something like this:

  #define PUBLICRO
  #define PUBLICRW
  #define SET(func)
  #define GET(func)
  // If SET() or GET() isn't specified, defaults to the member itself

 struct _GtkLabel
 {
   GtkMisc misc;
 
   PUBLICRW char *label SET(gtk_label_set_text);
   GSList *row;
   guint jtype : 2;
   gint  needs_clear : 1;
 };

Ideally, this information should come from (or go into) the .defs files.
