No, I believe it breaks abusive references
to stuff in unions ("type punning"),
not the normal structure-packing/casting rules.

I was just justifying the correctness
of code currently using connect_object w/o the slot_object being
a gtkobject, rather than advocating this as good programming style.
It is correct b/c:

	((A*) (GtkObject*) (A*) a_ptr) == (A*) a_ptr

regardless of the setting of strict-alias.
