Does not compile on MacOSX

[gamblevore]

Hi, this does not compile on MacOSX for me.

OSX: 13.2 (22D49)
Apple clang version 14.0.3 (clang-1403.0.22.14.1)
Target: arm64-apple-darwin22.3.0
InstalledDir: /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin

I have tried to fix it, but some issues remain.

If you like, I can make a fork and pull request for the fork? it contains some fixes I made to let it compile better. Just some missing headers. For example, it could not find malloc. But even after those fixes, it has issues I could not fix. Here below:
