>Description:
Function age_old_log in /usr/src/usr.sbin/newsyslog/newsyslog.c does
not check for a .bz2 file name suffix on the old log file name.  This
causes time-based rotation of bzip2-compressed log files to work
incorrectly - a new log is started each time newsyslog is run.

>How-To-Repeat:
In /etc/newsyslog.conf specify a 'when' value of, say, 168 and a '[ZJB]'
value of J.  This causes newsyslog to unconditionally start a new log
file, rather than weekly as you would expect.

>Fix:
Make function age_old_log also check for a .bz2 suffix on the old log
file name.

A workaround is to switch to gzip compression for old log files.
