/* 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. |

/* 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. |

|
Comment: Supports getopt, getopt_long, and getopt_long_only |
||||
|
and POSIXLY_CORRECT environment flag |
