> Hard link support for Windows does not work properly. There is some 
> refactoring needed in the code. Also, the code currently executes the fsutil 
> command to manipulate hard links. fsutil requires admin privileges on recent 
> versions of Windows. The main features needed are the ability to create hard 
> links to a file and count the number of hard links to a file. So we could use 
> mklink to create hard links and write a custom executable to count hard 
> links. Or use a custom executable to do both using Windows API's.
