@ -81,6 +81,11 @@ corrections:
Help for filan -L was bad, is now corrected to:
"follow symbolic links instead of showing their properties"
Address options fdin and fdout were silently ignored when not applicable
due to -u or -U option. Now these combinations are caught as errors.
Test: FDOUT_ERROR
Issue reported by Hendrik.
porting:
Socat included <sys/poll.h> instead of POSIX <poll.h>
Thanks to John Spencer for reporting this issue.
