The practical effect of Boost.Test requiring C++11 will be that everything
C++03 in the test matrix (using Boost.Test) will fail.

We'll have to deal with that in some way. One option is to just stop testing
C++03. Another is to migrate the libraries away from Boost.Test. Yet another
is to do nothing and pay no attention to failures.

Number two is the only option making any sense to me, but keep in mind that
many of the affected libraries have no active maintainers, and the CMT is
not terribly underworked.
