Feel free to send a bug report to EDG. 

Like I said, I checked each one and I agree with Intel C 10.1

I also counted about 300 similar cases where Intel
produced warning #593. I think there is quite a bit
of pointless computation going on.

I attach a patch again 4.3 snapshot 20071228.

Hint: Perhaps if this patch gets into 4.3 it would encourage
me to look at the other 300 cases ?
