&gt; I just did a test again, Debian Jessie, -Wall is there, the result
<br>
&gt; doesn&#39;t show any warning like you report. It is just make as we have
<br>
&gt; it default in the Makefiles:
<br>

<br>
I don&#39;t get any warnings either if I run the same command as you:
<br>

<br>

But I have -O2 param and if I add it to your command, I get the warnings:
