Exactly. Just a random note about how some people use config.guess: we have a testsuite for our library, which heavily exercises floating point. Since FP units vary between processors, we sometimes get results that differ in the minor digits of the output, and that's why we store output files for each platform, canonicalized by config.guess. I.e., we have directories testsuite/results/i686-pc-linux-gnu testsuite/results/sparc-sun-solaris2.7 ... If you change the canonicalized name of one of these, this would inflict major pain on us, since CVS doesn't easily allow to rename directories. I know how to fix this, but it involves messing with the CVS archive, and it's not a one-line change. I consider the proposed change totally useless, and not trivial to work around in situations as above.
