Ziemowit Laski 1a6213c3de NXConstStr.h: Update copyright date...
2004-08-12  Ziemowit Laski  <zlaski@apple.com>

        * objc/NXConstStr.h: Update copyright date; bracket with
        'extern "C"' for C++ use; make include syntax consistent
        by using <...> instead of "..."; hoist <objc/...> includes
        above the 'extern "C"' block.
        * objc/Object.h: Likewise.
        * objc/Protocol.h: Likewise.
        * objc/encoding.h: Likewise.
        * objc/hash.h: Likewise.
        * objc/runtime.h: Likewise.
        * objc/sarray.h: Likewise.
        * objc/thr.h: Likewise.
        * objc/typedstream.h: Likewise.
        * objc/objc-api.h: Add 'extern "C"' block for C++ use.
        (objc_static_instances): For C++ case, do away with
        zero-sized array.
        (objc_method): Hoist definition to file scope.
        (_objc_load_callback, _objc_object_alloc, class_get_class_method,
        class_get_instance_method, class_create_instance,
        class_get_class_name, class_get_instance_size,
        class_get_meta_class, class_get_super_class, class_get_version,
        class_is_class, class_is_meta_class, class_set_version,
        class_get_gc_object_type, class_ivar_set_gcinvisible,
        get_imp): Rename 'class' parameter to '_class'.
        * objc/objc-list.h: Add 'extern "C"' block for C++ use.
        * objc/objc.h: Update copyright date.
        (arglist_t): Provide a union tag.
