MiniZip64 - Copyright (c) 2009-2010 - Mathias Svensson - Built from MiniZip by Gilles Vollant
MiniZip - Copyright (c) 1998-2010 - by Gilles Vollant - version 1.1 64 bits from Mathias Svensson
Introduction
---------------------
MiniZip64 is built from MiniZip by Gilles Vollant ( http://www.winimage.com/zLibDll/minizip.html )
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 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.
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 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/ )
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.
Changed from MiniZip to MiniZip64
-------------------------------------
* Filenames has got a '64' at the end of them . eg unzip.c is now called unzip64.c
Changed from MiniZip 1.0 to MiniZip 1.1
---------------------------------------
* Added ZIP64 support for unzip ( by Even Rouault )
* Added ZIP64 support for zip ( by Mathias Svensson )
* Reverted some changed that Even Rouault did.

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)

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.
Okt-2009 - Mathias Svensson - Added support for BZIP2 as compression mode (bzip2 lib is required)
