It's an oversight in the implementation. All the sym link methods throw 
UOE on Windows editions older than Vista and that check shouldn't be in 
the createLink method. Thanks for finding this.

BTW: If you are testing with hard links then do you mind checking this 
method on Vista 64-bit or Windows Server 2008 64-bit. In particular, the 
case where the user doesn't have sufficient rights. It should throw an 
I/O exception indicating that the user doesn't sufficient rights. I've 
noticed on at least two machines that it fails silently which suggests 
this is a bug we need to forward to Microsoft (32-bit is okay).
