Thu Jul  6 11:54:03 2000  Owen Taylor  <otaylor@redhat.com>

	* gdk/gdk.h gdk/gdktypes.h gdk/linux-fb/gdkmain-fb.c
	gdk/nanox/gdkmain-nanox.c gdk/win32/gdkevents-win32.c
	gdk/win32/gdkinput-win32.c gdk/win32/gdkwin32.h
	gdk/x11/gdkmain-x11.c:

	Patch from George Liebl to add a GdkGrabStatus enumeration to use
	as a return value of gdk_*_grab(). Previously, we just
	returned the X11 values directly.
