        * objc/objc-act.c (add_method_to_hash_list, lookup_category):
        New functions.
        (lookup_method_in_hash_lists): New parameter indicating whether
        we are messaging 'Class' or 'id'.
        (check_duplicates): Likewise; do not assume all methods will
        be either class or instance methods.
        (generate_category, finish_class): Use lookup_category().
        (add_method): Use add_method_to_hash_list(); insert instance
        methods of root classes into the global class method hash table.
        (add_category): Use lookup_category(); avoid constructing
        duplicate categories.
        (really_start_method): Add method to corresponding @interface,
        if not already there (and if the @interface exists).
        (finish_message_expr, finish_objc): Adjust calls to
        check_duplicates().

        * objc.dg/method-6.m ('starboard'): Move prototype from 'Base' to
        'Derived', so that it is never considered a class method; add
        new warning for '+port' method ambiguity.
        * objc.dg/method-12.m: Include <objc/objc.h> instead of
        <objc/objc-api.h> (needed on Mac OS X).
        * objc.dg/method-13.m: New test.
