In the documentation (http://www.boost.org/doc/libs/1_53_0/libs/range/doc/html/range/reference/utilities/iterator_range.html) the return type is size_type, in trunk and 1.53 it is difference_type. (This is same issue was discussed and resolved in Ticket #5971, however class iterator_range might be forgotten there)" Bugs closed To Be Determined range Boost 1.53.0 Problem fixed
