What is the view on combinations like this:

   type seive is array (pos_integral range <>) of Boolean;
   for  seive'component_size use 8;
   pragma pack(seive);

or even this:

   type a_set is array (a_member) of Boolean;
   for  a_set'Component_Size use 1;
   pragma Pack(a_set);
   pragma Convention(C, Entity => a_set);

I guess these are somewhat redundant.
Does it matter?
