Hello, Recent changes in test_tools.hpp aimed at switching from Boost.Test to boost/detail/lightweight_test.hpp are causing lots of regressions, seemingly because the switch is not complete and the still linker misses some components from Boost.Test, see for instance http://tinyurl.com/yfohqh . As a result, the regression count has raised to 280 :( and possibly growing. I don't want to sound rude, but was it necessary to do this potentially dangerous change precisely now that we were so very close to being able to release a beta? If the change was aimed at solving some regression, it'd be good to know what the problem was so that maybe we can find some other, less drastic, workaround. Again, I don't want to offend anyone and maybe there's good reason for having commited the change. Thank you, Joaquín M López Muñoz Telefónica, Investigación y Desarrollo
