That would be nice, then I wouldn't have to use non-standard stuff.

I made my own easy-to-incorporate-into-any-project library - https://github.com/lelanthran/libds - just copy the ds_*.h and ds_*.c into a project and you're good to go.

I'm not saying it will work for you, but it works for me.

So it's not standard nor cross platform, but I consider Glib to be the defacto standard data structures library. Have you tried it out?
