fix some warnings and add .zip release

[ClaudioDaffra]

I fixed some warnings during the compilation and included a zip file with the compilation of Visual Studio 2022 and GCC, the latest versions

Thanks for taking the time to contribute! I appreciate the effort to clean up warnings.

However, I'd prefer to fix the warnings at their source rather than suppressing them with #pragma GCC diagnostic ignored across entire files. The fopen cast is a good catch though.

I'd also rather not include compiled binaries in the repo — users who need a build can compile from source, or binaries could be attached to a GitHub release instead.

Going to close this for now, but thanks again!
