title: CLS_LOG macro does not work in one class
body: <p>I'm using the Crashlytics CLS_LOG macro throughout my project. It's working everywhere except in one class, where I get <code>Implicit declaration of function 'CLS_LOG' is invalid in C99</code>. If I comment out the calls in that one class then the entire project compiles fine.</p>
  
  <p>I'm including Crashlytics in my prefix.pch like this:</p>
  
  <pre><code>#ifdef __OBJC__
      // Other imports
      #import "Crashlytics/Crashlytics.h"
      // Other imports
  #endif
  </code></pre>
  
  <p>I've trying clearing pre-compiled headers, reinstalling the Crashlytics framework, and more - nothing has helped.</p>
  
  <p>Any idea what could be breaking the macro in a single class?</p>
