title: How can I use ediff (emacs diff) as a diff/merge tool in Windows ClearCase?
body: <p>I'm forced to use ClearCase (Windows version) at work, and I want to use emacs ediff as a diff and merge tool. The problem with the ClearCase map file is that it requires .exe files - I've tried to specify a batch file calling <code>ediff</code> and it didn't work.</p>
  
  <p>I don't want to write a C/C++ program (it's been more than 10 years since I've coded anything in C for Win32) that will call <code>ediff</code> with the proper arguments. Is there a simpler way?</p>
