well, the two variants is:

	max_load = this_load = total_load = total_pwr = 0;

	max_load = 0;
	this_load = 0;
	total_load = 0;
	total_pwr = 0;

and the first one is more readable and more compact. (as long as the 
conceptual 'type' of the variables is the same - which it is in this 
case.)

anyway, this is something where reasonable people might disagree, and a 
tool should not force it one way or another. And this is the second time 
i raised this very example and Andy ignored my feedback and failed to 
notice the structural problem behind it (that a tool should only warn by 
default if it is _sure_ that there is a problem - otherwise the tool 
cannot be used for effective [i.e. automated] quality control), so i'm 
raising this point again, in a slightly more irritated tone ;-)
