Some GDK/GTK long options accept equals signs:

   --option=value

while others require that the value be a separate element of
the argument list:

   --option value

This patch (gtk-enf-990513-0) rationalizes things by making
every option that has a value accept either form.  It also
adds a few warning messages where previously arguments that
were not understood were simply ignored.
