+ * Used for both the console version and the Win32 GUI.  A lot of code is for

+ *
+ * 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.

+ * There is another problem, which isn't really a bug but isn't right either:
+ * When renaming "abcdef~1.txt" to "abcdef~1.txt~", the short name can be
+ * "abcdef~1.txt" again.  This has been reported on Windows NT 4.0 with
