My CFLAGS provoke two instances of the "'x' shadows a member 'this'" warning in filter_iterator constructors. Although the code is ok, I'd still like to ask for a change so that I may return to using -Werror without tinkering with the installed boost. :) /usr/local/include/boost/iterator/filter_iterator.hpp: In constructor `boost::filter_iterator<Predicate, Iterator>::filter_iterator(Predicate, Iterator, Iterator)': /usr/local/include/boost/iterator/filter_iterator.hpp:57: warning: declaration of 'end' shadows a member of 'this' /usr/local/include/boost/iterator/filter_iterator.hpp: In constructor `boost::filter_iterator<Predicate, Iterator>::filter_iterator(Iterator, Iterator)': /usr/local/include/boost/iterator/filter_iterator.hpp:63: warning: declaration of 'end' shadows a member of 'this' So long, and thanks for all the software! -- How many Vietnam vets does it take to screw in a light bulb?
