We hadn't noticed this because neither frange nor unsupported_range, both which use some of the default implementation, weren't being used much. We can never go wrong with setting VARYING ;-). Will commit after tests complete. gcc/ChangeLog: * value-range.cc (vrange::set): Set varying. (vrange::set_nonzero): Same. (vrange::set_zero): Same.
