+ * FreeBSD 5.1
+ *
+ * @changed EMX isms.
+ * @changed Removed timezone() function as it clashes with the timezone
+ *          variable defined in EMX and OGBSI6.
+ * @changed Changed CLK_TCK and CLOCKS_PER_SEC to 100.
+ * @changed Commented out tm_gmtoff and tm_zone in struct tm as LIBC doesn't
+ *          implement these yet.
+ *
+ * @todo    Implement tm_gmtoff and tm_zone members in struct tm.
+ * @todo    Implement clock_getres(), clock_gettime(), clock_settime(), nanosleep().
+ *          asctime_r(), ctime_r(), gmtime_r() and localtime_r() which are defined in
+ *          various POSIX standard revisions.
+ * @todo    Implement tzsetwall(), timelocal(), timegm() which are BSD specific.
