/* 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
