title: How can I use #pragma message() so that the message points to the file(lineno)?
body: <p>In order to add 'todo' items into my code, I want to put a message in the compiler output.<br>
  I would like it to look like this:</p>
  
  <pre><code>c:/temp/main.cpp(104): TODO - add code to implement this
  </code></pre>
  
  <p>in order to make use of the Visual Studio build output functionality to navigate to the respective line by double-clicking it.</p>
  
  <p>But the <code>__LINE__</code> macro seems to expand to an <code>int</code>, which disallows writing</p>
  
  <pre><code>#pragma message( __FILE__ "("__LINE__"): ..." )
  </code></pre>
  
  <p>Would there be another way?</p>
