+ * Dec 15, 2009, John Cunningham
+ * Added rewinddir member function
+ *
+ * Jan 18, 2008, Toni Ronkko
+ * Using FindFirstFileA and WIN32_FIND_DATAA to avoid converting string
+ * between multi-byte and unicode representations.  This makes the
+ * code simpler and also allows the code to be compiled under MingW.  Thanks
+ * to Azriel Fasten for the suggestion.
+ *
+ * Mar 4, 2007, Toni Ronkko
+ * Bug fix: due to the strncpy_s() function this file only compiled in
+ * Visual Studio 2005.  Using the new string functions only when the
+ * compiler version allows.
+ *
+ * Nov  2, 2006, Toni Ronkko
+ * Major update: removed support for Watcom C, MS-DOS and Turbo C to
+ * simplify the file, updated the code to compile cleanly on Visual
+ * Studio 2005 with both unicode and multi-byte character strings,
+ * removed rewinddir() as it had a bug.
+ *
+ * Aug 20, 2006, Toni Ronkko
+ * Removed all remarks about MSVC 1.0, which is antiqued now.  Simplified
+ * comments by removing SGML tags.
+ *
+ * May 14 2002, Toni Ronkko
+ * Embedded the function definitions directly to the header so that no
+ * source modules need to be included in the Visual Studio project.  Removed
+ * all the dependencies to other projects so that this very header can be
+ * used independently.
+ *
+ * May 28 1998, Toni Ronkko
+ * First version.
