See the compile-fail and link-fail rules in
tools/build/testing.jam. You really should use the version of
testing.jam on the "sane-testing" branch of the current CVS, as that
is the future of testing with bjam. Beman has not yet gotten around to
updating the HTML table-generation tools to work with that version,
which is why it's still sitting on the branch.
