title: How do I debug "INT_MAX undeclared"
body: <p><code>printf(INT_MAX);</code></p>
  
  <p>limits.h is included, for some reason it's not working in this particular project. In my testbed, it just works. I have no idea how to approach this problem other than removing every single file in the entire project until it starts working. This would be an inhuman amount of work. How can I find this bug faster? What are common causes of this?</p>
