There is no reason to prefer Component_Size in this particular case,
since the RM guarantees a component size
of 1 from the use of pragma Pack in this case for any Annex
C compliant compiler (and if you don't have an annex C
compiler you can forget about using rep clauses anyway :-)

P.S. Pat and others, please don't quote entire messages.
We are getting more and more threads where every message
contains complete copies of the same thing. Even worse is
when two people play this game together and generate a
quadratic text expansion.

I seem to see far more of this these days. I assume the
problem is some microsoft software that automatically
insists on quoting entire messages, sigh :-)
