That is very unlikely. widget.h *totally* depends on dialog.h. Also from
the redeclaration of Dlg_head and WListbox in wtools.h it is obvious it
should have included widget.h from the beginning.

With this patch we have a situation where wtools.h includes widget.h
which includes dialog.h. A very obvious and rather unbreakable chain of
dependencies.
