Made the "parent_class" pointer static. The pixbuf-engine coincidentially

2001-03-05  Michael Natterer  <mitch@gimp.org>

	* gtk/gtklabel.c: Made the "parent_class" pointer static. The
	pixbuf-engine coincidentially also failed to make one of it's
	parent_class pointers static, causing overwriting of GtkLabel's
	parent_class pointer in pixbuf_style_class_init().
	(Will commit the fix to the pixbuf-engine too).
