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.
