        PR fortran/28174
        * trans-array.c (gfc_conv_expr_descriptor): When building temp,
        ensure that the substring reference uses a new charlen.
        * trans-expr.c (gfc_conv_aliased_arg): Add the formal intent to
        the argument list, lift the treatment of missing string lengths
        from the above and implement the use of the intent.
        (gfc_conv_function_call): Add the extra argument to the call to
        the above.

        PR fortran/28167
        * trans-array.c (get_array_ctor_var_strlen): Treat a constant
        substring reference.
        * array.c (gfc_resolve_character_array_constructor): Remove 
        static attribute and add the gfc_ prefix, make use of element
        charlens for the expression and pick up constant string lengths
        for expressions that are not themselves constant.
        * gfortran.h : resolve_character_array_constructor prototype
        added.
        * resolve.c (gfc_resolve_expr): Call resolve_character_array_
        constructor again after expanding the constructor, to ensure
        that the character length is passed to the expression.
