        * Makefile.in (OBJC_DEPRECATED_H): Added struct_objc_category.h,
        struct_objc_ivar.h, struct_objc_ivar_list.h, struct_objc_method.h,
        struct_objc_method_list.h, struct_objc_module.h,
        struct_objc_protocol_list.h, struct_objc_symtab.h.
        * objc/deprecated/struct_objc_category.h: New.
        * objc/deprecated/struct_objc_ivar.h: New.
        * objc/deprecated/struct_objc_ivar_list.h: New.
        * objc/deprecated/struct_objc_method.h: New.
        * objc/deprecated/struct_objc_method_list.h: New.
        * objc/deprecated/struct_objc_module.h: New.
        * objc/deprecated/struct_objc_protocol_list.h: New.
        * objc/deprecated/struct_objc_symtab.h: New.
        * objc/deprecated/struct_objc_static_instances.h: New.
        * objc/objc-api.h: Definitions of deprecated structures moved into
        the above header fragment files in objc/deprecated/.  Include the
        files instead of definition the structures here.  Updated
        comments.
        * objc/runtime.h: Updated comments.  Do not include objc-api.h.
        (objc_set_enumeration_mutation_handler): Renamed to
        objc_setEnumerationMutationHandler.
        * objc-foreach.c (objc_set_enumeration_mutation_handler): Renamed
        to objc_setEnumerationMutationHandler.
        * objc/objc-exception.h (objc_set_exception_matcher): Renamed to
        objc_setExceptionMatcher.
        (objc_set_uncaught_exception_handler): Renamed to
        objc_setUncaughtExceptionHandler.
        * exception.c: Same changes.
