Well, what I have overlooked is that * means "infinitely small"
(arguably, * is a poor symbol for that meaning, but it was in the
documentations for quite some time), not "any" (as one would expect)
in the ports' version numbering system.

In our system:

* < 0
* < a1
* < r1

While, e.g.:

a1 < 0
a1 < r1
r1 < 0

I also attempted some alternatives, but they failed:

2.* < 2.a1
2 > 2.a1
2 = 2.0

Basically, 0 have the same meaning of what we expect in normal
numbering system, while we added additional concept like a, r (both <
0), and in order to catch these new concepts, we invented * and lived
with that for a decade.

I don't see a easy solution here, unfortunately: we can't simply
remove the a, r concepts because some software vendors don't issue
formal release for very long time, and we really need some symbols to
represent <0 numbers.

Cheers,
