Thanks for reporting that. Although I don't have MS-Windows I stared at 
the code a bit and I think I see what might be the problem. I found some 
other potential issues too (basically, I didn't switch from 
fstatat/lstat to readlinkat/readlink often enough so the code is still 
prone to EOVERFLOW problems). I installed the attached further patch, 
which I hope fixes things on MS-Windows and fixes the other issues too.
