to\n__rb_tree::_Node<_ValPtr> as a pointer to __rb_tree::_Node_base<_VoidPtr>.\n\nMany methods are adapted to take and return _Base_ptr in place of _Link_type\nwhich has been renamed into _Node_ptr.\n\nAs all node are stored as _Base_ptr have all methods working with this type\nand remove _Const_Base_ptr and _Const_Node_ptr and all methods associated with\nit.\n\nlibstdc++-v3/ChangeLog:\n\n * include/bits/stl_tree.h\n [_GLIBCXX_USE_ALLOC_PTR_FOR_RB_TREE]: New macro to control usage of the\n code required to support fancy allocator pointer type.\n
