The following compiles warning free on x86_64:

#include <gtk/gtk.h>

int
main (void)
{
  GHashTable *h;
  GType type1, type2;

  g_type_init ();
  h = g_hash_table_new (g_str_hash, g_str_equal);

  type1 = gtk_box_get_type ();
  g_hash_table_insert (h, "Box", (gpointer) type1);
  type2 = (GType) g_hash_table_lookup (h, "Box");

  g_print ("Type: %s\n", g_type_name (type2));

  return 0;
}

And gives the correct output when run:

Type: GtkBox

So the wrong usage of GUINT_TO_POINTER doesn't solve anything.
