MiniZip - Copyright (c) 1998-2010 - by Gilles Vollant - version 1.1 64 bits from Mathias Svensson

Introduction

---------------------

MiniZip 1.1 is built from MiniZip 1.0 by Gilles Vollant ( http://www.winimage.com/zLibDll/minizip.html )

When adding ZIP64 support into minizip it would result into risk of breaking compatibility with minizip 1.0.

All possible work was done for compatibility.

Background

---------------------

When adding ZIP64 support Mathias Svensson found that Even Rouault have added ZIP64 

support for unzip.c into minizip for a open source project called gdal ( http://www.gdal.org/ )

That was used as a starting point. And after that ZIP64 support was added to zip.c

some refactoring and code cleanup was also done.
