        * cp-tree.h (struct lang_decl_flags): Add hidden_friend_p
        bitfield.  Make dummy bitfield one bit smaller.
        (DECL_HIDDEN_FRIEND_P): Define.
        (pushdecl_maybe_friend): Declare.
        (pushdecl_top_level_maybe_friend): Declare.
        * decl.c (duplicate_decls): Add newdecl_is_friend parameter.
        Change prototype and all callers.  Add assertion that a
        DECL_ARTIFICIAL FUNCTION_DECL is not DECL_HIDDEN_FRIEND_P.  Set
        DECL_ANTICIPATED and DECL_HIDDEN_FRIEND_P in duplicated decl if
        appropriate.
