   * 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_W32".
   *
   * 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.
