* gdk/gdkdnd.c (gdk_window_register_dnd): X expects
longs, not uint32 for XChangeProperty, when
format == 32.
* gdk/gdkdnd.c (motif_read_initiator_info): Byte-swap
the MotifInitiatorInfo structure if necessary.
* gdk/gdkdnd.c: When extracting and constructing
Motif DND messages, don't use data.s[], data.l[]
since on 64bit architectures, these won't necessarily
be in the same place with data.b[].
* gtk/testdnd.c (target_drag_drop): Return TRUE for
drag_drop within the drop zone.
* gtk/gtkdnd.c (gtk_drag_dest_handle_event): Only send
a XmTRANSFER_FAILURE if no drop site is found, not
on every drop!
