/*
 * Workaround a DJGPP time functions problem which could cause the system
 * date not to advance at midnight when a BIOS time query function resets
 * the overflow flag before DOS has a chance to see it. Note that there's
 * still a race condition in the code below, it's just far less likely to
 * cause any harm. The real fix would be more complicated...
