- * 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 USE_GUI_WIN32".
- *
- * 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 <georgere@microsoft.com> wrote most of this.
- * Roger Knobbe <rogerk@wonderware.com> did the initial port of Vim 3.0.
