.. from zlib-1.2.7/contrib/minizip/ The original source was minizip 0.15beta from 1998. This update brings zip64 support (untested) and cleaner code. Furthermore, updates to future minizip should be much easier now, as my changes to the original source files from minizip are quite small. To make diffing to upstream minizip-src easier, I added the minizip source as exceptions in the astyle-scripts and left them in their own directory. Two custom functions from idSoftware - unzSetCurrentFileInfoPosition() and unzGetCurrentFileInfoPosition() - aren't needed anymore as minizip 1.1 has functions that do the same.
