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`.

Gradle also supports VirtualBox's shared folders.

Network file systems like Samba and NFS are not supported.

.Symlinks
--
File system watching is not compatible with symlinks.
If your project files include symlinks, symlinked files do not benefit from file system-watching optimizations.
