No, I didn't notice it. Sorry. And now that I have noticed it, I get
the same effect as you do.
Emacs 20.7 had CC Mode 5.25 (I think), and Emacs 21.3 has CC Mode 5.28.
Adaptive filling was introduced into CC Mode in version 5.26. This might
have something to do with the problem.

The indentation of C-style comment continuation lines (ones with /* ...
*/) is usually done by the function c-lineup-C-comments, and at a guess,
it is indenting a line to the same degree as the previous line, rather
than the previous none-blank line.
I'll take a closer look at this function sometime soon. I think it could
well be a sub-optimal feature in CC Mode which could do with improvement.
I don't see any quick way of fixing it right now.
You might want to submit this as a request to the CC Mode mailing list on
<[hidden email]>. So might I!
