# ZLib 1.2.3 Windows 64bit port

This is a copy of Windows port of Zlib 1.2.3.

* **Binaries** in the [lib/](lib) folder were taken from [64-bit build of Zlib](http://www.winimage.com/zLibDll/zlib123dllx64.zip).
* **Header files** in the [include/](include) folder were taken from [Zlib dev package](http://gnuwin32.sourceforge.net/downlinks/zlib-lib-zip.php).  

Configuration header `include/zconf.h` was patched to fix compilation on Windows - diff:
```
