   * os_win32.c

   * Used for both the console version and the Win32 GUI.  A lot of code is for
   * the console version only, so there is a lot of "#ifndef FEAT_GUI_MSWIN".
   *
   * Win32 (Windows NT and Windows 95) system-dependent routines.
   * Portions lifted from the Win32 SDK samples, the MSDOS-dependent code,
   * NetHack 3.1.3, GNU Emacs 19.30, and Vile 5.5.
   *
   * George V. Reilly <george@reilly.org> wrote most of this.
   * Roger Knobbe <rogerk@wonderware.com> did the initial port of Vim 3.0.

   * SUB STREAM (aka info stream) handling:
   *
   * NTFS can have sub streams for each file.  The normal contents of a file is
   * stored in the main stream, and extra contents (author information, title and
   * so on) can be stored in a sub stream.  After Windows 2000, the user can
   * access and store this information in sub streams via an explorer's property
   * menu item in the right click menu.  This information in sub streams was lost
   * when copying only the main stream.  Therefore we have to copy sub streams.
   *
   * Incomplete explanation:
   *	http://msdn.microsoft.com/library/en-us/dnw2k/html/ntfs5.asp
