iPhone - double parenthesis on ZipArchive... why?
<p>I am importing ZipArchive to use on an iPhone project.</p>

<p>When I compile it, I have trillions of errors saying "equality comparison with extraneous parenthesis", pointing to lines like this:</p>

<pre><code>if ((level==1))
</code></pre>

<p>Why is the programmer using double parenthesis? The error goes away if I remove the extra pair of parenthesis. Is it OK to do that?</p>

<p>thanks.</p>
