B<Q:>
While building nginx version 0.7.66, 0.8.35 or higher on Linux
the following warning messages are issued:


    
    warning: `sys_errlist' is deprecated;
        use `strerror' or `strerror_r' instead
    warning: `sys_nerr' is deprecated;
        use `strerror' or `strerror_r' instead








B<A:>
This is normal: nginx has to use the deprecated sys_errlist[] and sys_nerr
in signal handlers because strerror() and strerror_r() functions
are not Async-Signal-Safe.
