+       * lf.h (__attribute__): If not GCC and at least 2.7.0, define as
+       nothing.
+       (lf_printf): Add printf __attribute__, so the compiler will
+       automatically check the format string.
+
        * configure{,.in} (--enable-sim-icache): If argument is define,
        add -R to flags passed to igen.
