-         Changes
-
-    Oct-2009 - Defined ZPOS64_T to fpos_t on windows and u_int64_t on linux. (might need to find a better why for this)
-    Oct-2009 - Change to fseeko64, ftello64 and fopen64 so large files would work on linux.
-               More if/def section may be needed to support other platforms
-    Oct-2009 - Defined fxxxx64 calls to normal fopen/ftell/fseek so they would compile on windows.
-                          (but you should use iowin32.c for windows instead)

-
-  ------------------------------------------------------------------------------------
-  Decryption code comes from crypt.c by Info-ZIP but has been greatly reduced in terms of
-  compatibility with older software. The following is from the original crypt.c.
-  Code woven in by Terry Thorsen 1/2003.
-
-  Copyright (c) 1990-2000 Info-ZIP.  All rights reserved.
-
-  See the accompanying file LICENSE, version 2000-Apr-09 or later
-  (the contents of which are also included in zip.h) for terms of use.
-  If, for some reason, all these files are missing, the Info-ZIP license
-  also may be found at:  ftp://ftp.info-zip.org/pub/infozip/license.html
-
-        crypt.c (full version) by Info-ZIP.      Last revised:  [see crypt.h]
-
-  The encryption/decryption parts of this source code (as opposed to the
-  non-echoing password parts) were originally written in Europe.  The
-  whole source package can be freely distributed, including from the USA.
-  (Prior to January 2000, re-export from the US was a violation of US law.)
-
-        This encryption code is a direct transcription of the algorithm from
-  Roger Schlafly, described by Phil Katz in the file appnote.txt.  This
-  file (appnote.txt) is distributed with the PKZIP program (even in the
-  version without encryption capabilities).
-
-        ------------------------------------------------------------------------------------
-
-        Changes in unzip.c
-
-        2007-2008 - Even Rouault - Addition of cpl_unzGetCurrentFileZStreamPos
-  2007-2008 - Even Rouault - Decoration of symbol names unz* -> cpl_unz*
-  2007-2008 - Even Rouault - Remove old C style function prototypes
-  2007-2008 - Even Rouault - Add unzip support for ZIP64
-
-        Copyright (C) 2007-2008 Even Rouault
-
-
-        Oct-2009 - Mathias Svensson - Removed cpl_* from symbol names (Even Rouault added them but since this is now moved to a new project (minizip64) I renamed them again).
-  Oct-2009 - Mathias Svensson - Fixed problem if uncompressed size was > 4G and compressed size was <4G
-                                should only read the compressed/uncompressed size from the Zip64 format if
-                                the size from normal header was 0xFFFFFFFF
-  Oct-2009 - Mathias Svensson - Applied some bug fixes from paches recived from Gilles Vollant
-        Oct-2009 - Mathias Svensson - Applied support to unzip files with compression mathod BZIP2 (bzip2 lib is required)
-                                Patch created by Daniel Borca
-
-  Jan-2010 - back to unzip and minizip 1.0 name scheme, with compatibility layer

-         For more info read LICENSE-MiniZip.txt
-
-         Changes
-   Oct-2009 - Mathias Svensson - Remove old C style function prototypes
-   Oct-2009 - Mathias Svensson - Added Zip64 Support when creating new file archives
-   Oct-2009 - Mathias Svensson - Did some code cleanup and refactoring to get better overview of some functions.
-   Oct-2009 - Mathias Svensson - Added zipRemoveExtraInfoBlock to strip extra field data from its ZIP64 data
-                                 It is used when recreting zip archive with RAW when deleting items from a zip.
-                                 ZIP64 data is automaticly added to items that needs it, and existing ZIP64 data need to be removed.
-   Oct-2009 - Mathias Svensson - Added support for BZIP2 as compression mode (bzip2 lib is required)
-   Jan-2010 - back to unzip and minizip 1.0 name scheme, with compatibility layer
