is_incrementable.hpp: checks whether ++x is well-formed pointee.hpp: value_type of iterators or smart pointers indirect_reference.hpp: reference type of iterators or smart pointers indirect_iterator.hpp indirect_iterator_member_types.cpp Use pointee/indirect_reference to select value/reference type. iterator_concepts.hpp: Fixed interoperable test. Hardly tests enough, but it's a start minimum_category.hpp: Better error messages for vc6 indirect_iterator_test.cpp: Workarounds for compilers without SFINAE static_assert_same.hpp: Informative error reports; added a macro. zip_iterator_test.hpp: Added missing #include Jamfile: made zip_iterator test pass with vc6/stlport [SVN r21514]
