Alex Brainman e83601b435 os: use WIN32_FIND_DATA.Reserved0 to identify symlinks ... os.Stat implementation uses instructions described at https://blogs.msdn.microsoft.com/oldnewthing/20100212-00/?p=14963/ to distinguish symlinks. In particular, it calls GetFileAttributesEx or FindFirstFile and checks either WIN32_FILE_ATTRIBUTE_DATA.dwFileAttributes or WIN32_FIND_DATA.dwFileAttributes to see if FILE_ATTRIBUTES_REPARSE_POINT flag is set. And that seems to worked fine so far. But now we discovered that OneDrive root folder is determined as directory: c:\>dir C:\Users\Alex | grep OneDrive 30/11/2017 07:25 PM <DIR> OneDrive c:\> while Go identified it as symlink. But we did not follow Microsoft's advice to the letter - we never checked WIN32_FIND_DATA.Reserved0. And adding that extra check makes Go treat OneDrive as symlink. So use FindFirstFile and WIN32_FIND_DATA.Reserved0 to determine symlinks.
