    // PHP on Windows has limited support for file permissions. Usually each of
    // "user", "group" and "other" use one octal digit (3 bits) to represent the
    // read/write/execute bits. On Windows, chmod() ignores the "group" and
    // "other" bits, and fileperms() returns the "user" bits in all three
    // positions. $expected_mode is updated to reflect this.
