        * cp-tree.h (LOOKUP_ALLOW_FLEXARRAY_INIT): New flag value.
        * typeck2.c (digest_init_r): Raise an error for non-static
        initialization of a flexible array member.

        process_init_constructor_array, process_init_constructor_record,
        process_init_constructor_union, process_init_constructor): Add the
        flags parameter and pass it thru.
        (store_init_value): Pass LOOKUP_ALLOW_FLEXARRAY_INIT parameter to
        digest_init_flags for static decls.
