+/* Getopt for Microsoft C
+This code is a modification of the Free Software Foundation, Inc.
+Getopt library for parsing command line argument the purpose was
+to provide a Microsoft Visual C friendly derivative. This code
+provides functionality for both Unicode and Multibyte builds.
+
+Date: 02/03/2011 - Ludvik Jerabek - Initial Release
+Version: 1.0
+Comment: Supports getopt, getopt_long, and getopt_long_only
+and POSIXLY_CORRECT environment flag
+License: LGPL
+
+Revisions:
+
+02/03/2011 - Ludvik Jerabek - Initial Release
+02/20/2011 - Ludvik Jerabek - Fixed compiler warnings at Level 4
+07/05/2011 - Ludvik Jerabek - Added no_argument, required_argument, optional_argument defs
+08/03/2011 - Ludvik Jerabek - Fixed non-argument runtime bug which caused runtime exception
+08/09/2011 - Ludvik Jerabek - Added code to export functions for DLL and LIB
+02/15/2012 - Ludvik Jerabek - Fixed _GETOPT_THROW definition missing in implementation file
+08/01/2012 - Ludvik Jerabek - Created separate functions for char and wchar_t characters so single dll can do both unicode and ansi
+10/15/2012 - Ludvik Jerabek - Modified to match latest GNU features
+06/19/2015 - Ludvik Jerabek - Fixed maximum option limitation caused by option_a (255) and option_w (65535) structure val variable
