In order to that, the dereference operators need to be const. The conversions to the underlying iterator can be const too. PR c/92472 * include/parallel/multiway_merge.h (_GuardedIterator::operator*) (_GuardedIterator::operator _RAIter, _UnguardedIterator::operator*) (_UnguardedIterator::operator _RAIter): Add const qualifier. (operator<(_GuardedIterator&, _GuardedIterator&) (operator<=(_GuardedIterator&, _GuardedIterator&) (operator<(_UnguardedIterator&, _UnguardedIterator&) (operator<=(_UnguardedIterator&, _UnguardedIterator&): Change parameters to const references.
