No. that is a usual C programming construct so that inside the loop
you can use a break; It is much more readable that sticking in a goto exit;
even though the assembly code is identical. A break must goto a forward point,
and _always_ at the end of the current loop. When you see the break, you can
find where it is going easily, while a goto can jump across the moon and you
have to search for the target...
