/// @assertion String targetSync()
/// Synchronously gets the target of the link. Returns the path to the target.
///
/// If the returned target is a relative path, it is relative to the directory
/// containing the link.
///
/// If the link does not exist, or is not a link, throws a FileSystemException.
///
/// @description Check that this method returns the target of the link. Tests
/// link as a target.
///
/// @note The test should run with the Administrator priveleges on Windows.
/// Dart API Spec reads:
/// In order to create a symbolic link on Windows, Dart must be run in
/// Administrator mode or the system must have Developer Mode enabled, otherwise
/// a FileSystemException will be raised with ERROR_PRIVILEGE_NOT_HELD set as
/// the errno when this call is made.
