Our standard practice is to keep the workaround in place for future
versions using BOOST_TESTED_AT(), which tends to ensure that library
code doesn't break when a user gets a new compiler and also gives us a
way to locate all workarounds that can be limited to earlier versions
when a later version comes out.
