"If the named file is a symbolic link, the stat() function shall continue
pathname resolution using the contents of the symbolic link, and shall return
information pertaining to the resulting file if the file exists."
In other words, if file is a broken symlink, symlink resolution MUST take
place, at which point, the brokenness of the symlink means that stat() MUST
fail with ENOENT because a component of the path does not exist. Cygwin is
correct here, as is Linux.
