+
+ 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 - 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)
