On Windows, the mode bits reported by [Lstat] and [Stat] for reparse points changed. Mount points no longer have [ModeSymlink] set, and reparse points that are not symlinks, Unix sockets, or dedup files now always have [ModeIrregular] set. This behavior is controlled by the winsymlink setting. For Go 1.23, it defaults to winsymlink=1. Previous versions default to winsymlink=0.
