But.. I would highly recommend that you do both of the above. The first one
makes it so that someone not using BB can make use of the test (for
whatever reason they like). And the second one removes it from the test
results table so that it reduces the noise.
But if that is not what you are after you can also use the Boost Predef
checks to set those options. As they support more than just a specific
compiler version. See the docs for how to use that here <
