- *
- * Mar 15, 2011, Toni Ronkko
- * Defined FILE_ATTRIBUTE_DEVICE for MSVC 6.0.
- *
- * Aug 11, 2010, Toni Ronkko
- * Added d_type and d_namlen fields to dirent structure. The former is
- * especially useful for determining whether directory entry represents a
- * file or a directory. For more information, see
- * http://www.delorie.com/gnu/docs/glibc/libc_270.html
- *
- * Aug 11, 2010, Toni Ronkko
- * Improved conformance to the standards. For example, errno is now set
- * properly on failure and assert() is never used. Thanks to Peter Brockam
- * for suggestions.
- *
- * Aug 11, 2010, Toni Ronkko
- * Fixed a bug in rewinddir(): when using relative directory names, change
- * of working directory no longer causes rewinddir() to fail.
- *
- * 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.
