Elaborate on writing proxied responses to files. Added a note that restrictions imposed by proxy_max_temp_file_size, proxy_temp_file_write_size and Co. do not apply to responses that will be cached or saved on disk.

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

<programlisting>
warning: `sys_errlist' is deprecated;
    use `strerror' or `strerror_r' instead
warning: `sys_nerr' is deprecated;
    use `strerror' or `strerror_r' instead
</programlisting>

</para>

<para>
<initial>A:</initial>
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.
