--- Comment #5 from Paolo Carlini <paolo.carlini at oracle dot com> 2013-01-27 08:35:37 UTC --- Uhhmm, I wasn't considering the fact that the testcases added for 53339 are now xfailed?!? So what? If that's the case (for now at least) we could as well revert the core of the 53339 changes, that is go back to the 4.7 situation and just use std::_Select1st<value_type>?!?
