--- Comment #23 from Jonathan Wakely <redi at gcc dot gnu.org> --- The other improvement we could make for C++20 is to replace <iterator> in <bits/ranges_algobase.h> with smaller pieces, as it doesn't need the definition of std::streambuf_iterator: --- a/libstdc++-v3/include/bits/ranges_algobase.h +++ b/libstdc++-v3/include/bits/ranges_algobase.h @@ -33,7 +33,10 @@ #if __cplusplus > 201703L #include <compare> -#include <iterator> +#include <bits/stl_iterator_base_types.h> +#include <bits/stl_iterator_base_funcs.h> +#include <bits/stl_iterator.h> +#include <bits/range_access.h> #include <bits/ranges_base.h> // ranges::begin, ranges::range etc. #include <bits/invoke.h> // __invoke #include <bits/cpp_type_traits.h> // __is_byte And <bits/streambuf_iterator> doesn't need <streambuf>, just <iosfwd>.
