Is memcmp_s (or a variant thereof) a win in practice?  It covers the 
case pretty well where you try to copy a dynamically sized buffer to the 
start of a statically sized one.  I don't want to say that it doesn't 
happen, but it seems to be rather rare, and I expect most calls to 
memcpy_s would use the same expression for both sizes.
