So to be clear, i was proposing leaving the structure public, but
embedding the structure in a private structure.
Since you're referring the the structure via a pointer, you can point
into the middle of the private structure.  Users
of the api could then access the public size field, but it wouldn't be
the *real* size field, just an int sized truncated copy of the size
field.
The real size field would be out of view a bytes before where the
pointer points (or after the structure block).

Anyway, sounds like it's water under the bridge now and people have
coped, so maybe not worth persuing.
