title: enums to be defined as uint8_t variables in structure
body: <p>I have an enum in a structure:</p>
  
  <pre class="lang-c prettyprint-override"><code>enum Days : uint8_t
  {
    day1 =1,
    day2 =2,
    day2 =3
  }
  
  struct Hi
  {
    Days days;
  }
  </code></pre>
  
  <p>On compilation, I get an error <code>Scoped enums not available in this version</code>.
  I need all my enums to be an <code>uint8_t</code> type and defined in the structure.</p>
