Despite the existence of Dhrystone 2.1, it turns out that most people,
seeing unlabeled Dhrystones, think it's 1.1, if only because when
you backtrack what they meant, that's what you find. At least it was
labeled, and their performance document gives nubmers for both,
and they have a typical ratio. [Now, I still find the number puzzling, but..]
