Modifications for Zip64 support
Copyright (C) 2009-2010 Mathias Svensson ( http://result42.com )
For more info read MiniZip_info.txt
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)
