/*
 * old_syslog library routine. Used if syslogd is not present. This routine
 * has a subset of the functions of syslogd. It always outputs to
 * /etc/syslog, and it accepts only one string, and does no error checking.
 * It also prints the facility/log level as a number.
 *
 * If you're sure syslogd will be available when your program is run (or you
 * want syslog() to do nothing if it isn't), create a dummy old_syslog() that
 * simply returns. This will make your program smaller.
