+       binary-io: avoid potential compilation warning
+       * lib/binary-io.h [__DJGPP__]: Avoid null preprocessor
+       directives.
+
        fflush: avoid compilation error on NetBSD
        * lib/fflush.c (update_fpos_cache): Use a union to safely convert
        between off_t and fpos_t, since the latter is sometimes a struct.
