Add missing gdk_rectangle_get_type() prototype.

Mon Jun 11 18:15:16 2001  Owen Taylor  <otaylor@redhat.com>

	* gdk/gdk.h: Add missing gdk_rectangle_get_type() prototype.

	* gtk/gtk[hv]scale.c: Include math.h, stdlib.h

	* gdk/gdkpango.h gtk/gtkclist.c gtk/gtkentry.c gtk/gtkmain.[ch]
	  gtk/gtkspinbutton.c gtk/gtkstyle.c gtk/gtktextbuffer.c
	  gtk/gtktextdisplay.c gtk/gtktextiter.[ch]
	  gtk/gtktextlayout.c gtk/gtktexttag.[ch] gtk/gtkwidget.c: Adapt
	  to recent changes in Pango.

	* tests/testgtk.c: Set language tags with gtk_label_set_markup()
	  to test whether the basic engine honors them.
