   Not if .active is a public member of the object.  Or am I missing a
   subtler point?

There shouldn't be any public data members.  The fact that there is,
is itself a mistake.

   Again, if the .active element is a public member of the structure.  I
   fail to see what a macro or an inline function would buy you here,
   exactly.

If you get people to use the macro or inline, you can get rid of the
public data member eventually.

Speaking as somebody who is currently porting an application to 1.1.1
to 1.1.16, the argument that ``everybody uses .active so it can't go
away'' rings a little hollow!  (ok_button, anybody?)
