incrementable_iterator_tag -> incrementable_traversal_tag single_pass_iterator_tag -> single_pass_traversal_tag iterator_categories.hpp - added writability stripping to new_category_to_access for iterator adaptors based on iterators with new-style tags ReturnTag->AccessTag / returns->access Fixed a bug which would rule out user-defined access/traversal tags - we weren't accounting for tag convertibility without public inheritance. iterator_facade.hpp - Workaround for a Borland const-dropping bug. detail/categories.hpp - fixed is_tag so it doesn't rely on inheritance for detection concept_tests.cpp - added new tests, use static_assert_same for better feedback on failure iterator_adaptor_test.cpp workarounds for CWPro7, use static_assert_same for better feedback on failure wiped out #if 0 section unit_tests.cpp - factored static_assert_same into a separate file [SVN r1296]
