Sadly, I have to admit that I do not have Vista around, and I have been 
trying very hard to avoid it up until now. It seems I'll have to go get 
me a copy :-(

Amazing. So Windows Vista has "junction points" 
(http://msdn.microsoft.com/en-us/library/bb968829(VS.85).aspx), but also 
has symbolic links 
(http://msdn.microsoft.com/en-us/library/aa365680(VS.85).aspx). And 
guess what - they are not the same! Blah....

On Windows, rsyncrypto uses the GetFileAttributesEx function to figure 
out what the type of the file is. The docs seem to suggest that junction 
points will have FILE_ATTRIBUTE_REPARSE_POINT set. I'll see what can be 
done with the code to make it work. As I don't have access to a Vista 
machine, if you could verify that point, it would be much appreciated. A 
tiny program to print (even hexa-decimal) the attributes of a junction 
point and send the result here would be enough.

Can you try compiling the attached patch letting me know how it fares?
