        * decl.c (cp_fname_init): Decay the initializer to pointer.
        (cp_make_fname_decl): Set DECL_DECLARED_CONSTEXPR_P,
        DECL_VALUE_EXPR, DECL_INITIALIZED_BY_CONSTANT_EXPRESSION_P.
        Don't call cp_finish_decl.
        * pt.c (tsubst_expr) [DECL_EXPR]: Set DECL_VALUE_EXPR,
        DECL_INITIALIZED_BY_CONSTANT_EXPRESSION_P.  Don't call cp_finish_decl.
        * constexpr.c (cxx_eval_constant_expression) [VAR_DECL]:
        Handle DECL_VALUE_EXPR.
