title: Is it possible to define {$IFDEF} for more than one directive at once?
body: <p>Is it possible to define more than one conditional in one {$IFDEF} directive ?<br>
  I would like to have syntax like this:</p>
  
  <pre><code>{$IFDEF Condition1 OR Condition2} DoSomething; {$ENDIF}
  {$IFDEF Condition1 AND Condition2} DoSomethingElse; {$ENDIF}
  </code></pre>
  
  <p>Thanks</p>
