MiniZip64 - Copyright (c) 2009-2010 - Mathias Svensson - Built from MiniZip by Gilles Vollant
Introduction
---------------------
MiniZip64 is built from MiniZip by Gilles Vollant ( http://www.winimage.com/zLibDll/minizip.html )
When adding ZIP64 support into minizip it would result into breaking compatibility with current minizip.
And since breaking compatibility in minizip is not wanted. I decided to create a fork of minizip
and create minizip64.
Even though MiniZip64 is build from MiniZip, all functions and struct's have changed name so that it
would not collide with each other.
Background
---------------------
When adding ZIP64 support I 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.
Changed from MiniZip to MiniZip64
-------------------------------------
* Filenames has got a '64' at the end of them . eg unzip.c is now called unzip64.c
* Added ZIP64 support for unzip ( by Even Rouault )
* Added ZIP64 support for zip ( by Mathias Svensson )
* Reverted some changed that Even Rouault did.
* Bunch of patches received from Gulles Vollant that he received for MiniZip from various users.
* Added unzip patch for BZIP Compression method (patch create by Daniel Borca)
* Added BZIP Compress method for zip
* Did some refactoring and code cleanup

Resources
ZipLayout http://result42.com/projects/ZipFileLayout
Command line tool for Windows that shows the layout and information of the headers in a zip archive.
Used when debugging and validating the creation of zip files using MiniZip64
ZIP App Note http://www.pkware.com/documents/casestudies/APPNOTE.TXT
Zip File specification
Notes.
* To be able to use BZip compression method in zip64.c or unzip64.c the BZIP2 lib is needed and HAVE_BZIP2 need to be defined.

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)
