Multi-character constant warnigs
<p>Why is this warning? I think there are many cases when is more clear to use multi-char int constants instead of "no meaning" numbers or instead of defining const variables with same value. When parsing wave/tiff/other file types is more clear to compare the read values with some 'EVAW', 'data', etc instead of their corresponding values.</p>

<p>Sample code:</p>

<pre><code>int waveHeader = 'EVAW';
</code></pre>

<p>Here is a warning. Why?</p>
