title: How do I suppress the "ISO C++ does not support ‘__int128’ warning?
body: <p>I'm compiling my code with gcc, with the <code>-Wall -Wextra -Wpedantic</code> switches and a non-extension standard set (say it's <code>-std=c++14</code>). But - I want to make an exception to that rule and use <code>__int128</code>. This gets me a warning:</p>
  <pre><code>warning: ISO C++ does not support ‘__int128’ for ‘hge’ [-Wpedantic]
  </code></pre>
  <p>Can I suppress the specific warning about <code>__int128</code>? Alternatively, can I temporary suppress <code>-Wpedantic</code> before and after the use of this type?</p>
