I was able to compile it after I linked an already compiled zlib library, I'm too much of a noob to understand why including zlib.h wasn't enough to recognize the decompress command, I always got an "undefinied reference error". Anway, after finally having compiled it, the program still do...

Thanks for the files, unfortunately it doesn't compile either. I even tried switched from Visual Studio to MinGW, maybe it's a Windows specific problem, I really don't know enough about this.

Would a compiled version be too much to ask for? I made some quick attempts that didn't work out, so I would be really thankful for one.
