Exactly what packing would this keyword imply, and also what object model
would it imply?

Reading the ANSI-C spec, I do not see any promises of the "precise" control
being referred to.  I see instead, great latitude provided to compiler
writers in order to allow efficient code be generated on a given machine.
Perhaps you can clarify what constraints provided by the ANSI-C spec meet
your ideas of "precise control" ?
