On Windows, [EvalSymlinks] no longer evaluates mount points,
which was a source of many inconsistencies and bugs.
This behavior is controlled by the `winsymlink` setting.
For Go 1.23, it defaults to `winsymlink=1`.
Previous versions default to `winsymlink=0`.

On Windows, [EvalSymlinks] no longer tries to normalize
volumes to drive letters, which was not always even possible.
This behavior is controlled by the `winreadlinkvolume` setting.

The [GetsockoptInt] function is now supported on Windows....

The [Stat] function now sets the [ModeSocket] bit for
files that are Unix sockets on Windows. These files are identified
