It's the one required by the test. In the case of Boost.Thread tests
it's both multi-threaded-static-link and multi-threaded-dynamic-link.
The bug was that the test would specify those but the libraries would
specify another and the Boost.Build was not correctly imposing the one
the test wanted.

We probably should, and for cw-8.3 we do. Metacomm runs the usual debug
versions, which includes single and multi threaded. While the ones I run
are release.

And what I would suggest is that for people that are running "duplicate"
tests. To coordinate to have some run debug and others release.
