Also, all those standards and docs would not say which sequence you were supposed to get, or if it would be the same values for different libcs, different OSes, 32-vs-64 bit cpus, little -vs- big endian and so forth, so if you sent a source to a program that depended on the output being a certain sequence, the next person with not-exactly-the-same-machine would probably not get that exact sequence anyhow.
