/* 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.

Version: 1.0
Comment: Supports getopt, getopt_long, and getopt_long_only
and POSIXLY_CORRECT environment flag
