Well, the 'beurk' isn't correct, since the second
parameter isn't a pointer to an int, it is an int.

On some platforms, it work work to do:

  g_list_foreach(list, (GFunc)g_string_free, GINT_TO_POINTER (TRUE));

However, this isn't portable, and will break horribly on
some architectures. What you should do is simply use a helper
function:

 void
 free_string (gpointer string, gpointer data)
 {
   g_string_free (string, NULL);
 }

 g_list_foreach (list, free_string, NULL);

It's not currently possible with GTK+. (You'd have to
have two programs talking to each other via IPC)
