The idea is that switching to a whole new OS or compiler really does
result in a different animal, which should have a different name to
reduce confusion.  (I didn't make this decision, but it seems
reasonable to me.)  Upgrades are fine, but those should only be
moving the version numbers.

Yeah, ideally we would not bother with the manual labeling of
versions.  I know how to scrape compiler versions out of the
build logs, and I always do that when I am interested in
compiler versions, rather than trusting the labels.  But it's
much harder to identify OS version from the build logs ...
