title: Is there a way of compiling C11 to C89?
body: <p>One of my (embedded) targets only has a C89 compiler.</p>
  
  <p>I am working on a (hobby) project which targets multiple devices.</p>
  
  <p>Is there a way of compiling (transpiling?) a C11 code base into C89?</p>
  
  <p>(Otherwise I will have to code like it's 1989, literally.)</p>
