object_core.hpp - allow wrapping of objects which take object managers in their constructors.
forward.hpp pointer_holder.hpp value_holder.hpp test/long.[py/cpp] pointee.hpp, - begin making borland work. cv_category.hpp, referent_storage.hpp instance.hpp self.hpp - removed flotsam signature.hpp - use vector instead of list destroy.hpp - removed needless complication make_keyword_range_fn.hpp - support for simpler init using vectors class_converters.hpp - workaround for pro7 inheritance.hpp - simplified; took out pro7 workarounds; factored out inheritance_query.hpp to reduce recompilation dependencies make_ptr_instance.hpp - add missing typename registry.cpp - add a little invariant checking for metrowerks class.cpp - stopped relying on class_id typedef test/data_members.cpp - added a few more tests to make sure things compile at least. test/destroy_test.cpp - removed cheating has_trivial_destructor tests test/enum.cpp - added some pro7 workarounds test/virtual_functions.[py/cpp] - added _some_ tests for callbacks which return by reference.
