Spacing and GtkBox

["Padraig O'Briain" <Padraig Obriain ireland sun com>]

I was looking at the code of GTK+ and I noticed in gtkbox.h the struct _GtkBox 
contains a catiable called spacing which is gint16.

In gtkbbox.h the structure _GtkButtonBox contains a GtkBox and also contains a 
variable called spacing which is gint.

I have two questions:

1) Should the variable called spacing in _GtkBox be gint?

2) Could the variable spacing in _GtkButtonBox be omitted and the variable 
spacing in _GtkBox be used instead?
