- * sprintf_irc is optimized for the formats: %c, %s, %lu, %d and %u.
- * Where %lu actually equals %l09u (for printing time_t timestamps).
- *
- * sprintf_irc is NOT optimized for any other format and resorts to using
- * the normal sprintf when it encounters a format it doesn't understand
- * (including padding, width, precision etc).
- *
- * The following benchmark was measured on a PPro200 with linux 2.0.30,
- * libc 5.4.28, compiled with gcc-2.7.2.1 with -O3.
