To avoid wasting space in structures, it makes sense to place fields 
smaller than the alignment width together in the structure definition.  
If one were to do this and follow your proposal, some structures may need 
multiple "private" and "public" comments, which seems undesirable.  The 
alternative, wasting memory, also seems undesirable.  Perhaps you might 
have a proposal for a way to resolve this?
