Good point, I'll undo those bits. Thanks.
* include/std/concepts (__boolean): Remove. (__detail::__boolean_testable_impl, __detail::__boolean_testable): Add new helper concepts. (__detail::__weakly_eq_cmp_with, totally_ordered, totally_ordered_with) (predicate): Use __boolean_testable instead of boolean. * libsupc++/compare (__detail::__partially_ordered, _Synth3way): Likewise. Tested powerpc64le-linux, committed to master.
