	Miscellaneous minor fixes to remove ANSI C incompatibilities

	* gdk/gdkregion.c gtk/gtkclist.c: fix // comments

	* gdk/gdkdnd.c gdk/gdkinputcommon.h: change types of
	some arguments to ANSI functions

	* gtk/gtkcombo.c gtk/gtktree.c: fix casts of function pointers
	  to void *

	* gtk/gtkmain.c: An actual bug! (in deprecated gtk_input_add_interp)

	* gtk/gtknotebook.h: Bitfields must be gint or guint. (and should
	  be guint)

	* gtk/gtkstatusbar.c: trailing ';'

	* gtk/testgtk.c: GList where there should have been GSList

	* glib.h gutils.c : changed g_strcasecmp
	  to take gchar* not guchar*

	* testglib.c: Remove trailing ; after functions
