Well, it was:

Surely there is a lot of room for improvement (as illustrated by,
but the above sounds like you think they are in flux, and if so, you
should list the particular issues that led you to this conclusion, or
otherwise it's FUD. For instance, surely you could check 1.33.1 report
pages before making the claim that dynamic_bitset wasn't tested with
CW 8.3 (or any other toolset)?

That's much appreciated.

The former.

I don't think it's that bad, really: library maintainers don't follow
the links because they know what their tests are, and have a working
copy anyway, and most users don't follow them because they are not
interested in that level of details (or may be they don't know where
to report a broken link, which is a problem, but hardly an indication
of the regression tests being in flux).
