title: How can include case sensitive header files in MAC OS?
body: <p>My code is having two header files with same name but different case.(For ex:- <code>dataStore.h</code> and <code>DataStore.h</code>)
  It is a maintenance project so I can not change the name of the files.
  While running the make file, it is giving a warning as below:</p>
  
  <p><strong>specified path differs in case from file name on disk [-Wnonportable-include-path]</strong></p>
  
  <p>And after that it fails.
  Adding <code>-Wnonportable-include-path</code> in the <code>makefile</code> has no effect overall.
  If anybody has used the above flag and it worked on MAC OS or any other way to solve this issue, please do let me know.</p>
