/**
 * @assertion void createSync(
 *  String target, {
 *  bool recursive: false
 *  })
 *  Synchronously create the link. Calling createSync on an existing link will
 *  throw an exception.
 *
 *  If recursive is false, the default, the link is created only if all
 *  directories in its path exist. If recursive is true, all non-existing path
 *  components are created. The directories in the path of target are not
 *  affected, unless they are also in path.
 *
 *  On the Windows platform, this call will create a true symbolic link instead
 * of a Junction. 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.
 *
 *  On other platforms, the posix symlink() call is used to make a symbolic link
 *  containing the string target. If target is a relative path, it will be
 *  interpreted relative to the directory containing the link.
 * @description Checks that on the Windows platform relative paths to the target
 * is not converted to absolute paths (as it was in the past)
