title: delphi 7 - create a custom warning
body: <p>I'm using Delphi 7, and I want to create a custom warning message (which will be shown at compile time), so I can warn other programmers on some modifications. I've searched on the internet but I didn't found anything relevant. </p>
  
  <p>Other solutions, are welcomed as well, as long other programmers are warned about things I want, when they compile/build the sources.</p>
