here is a patch for the ncdu. As version 2.0.* are based on Zig I decided to create a new variable instead of updating the old one.
FIY this is my first encounter with Zig and I just briefly swept through the documentation and I don't know if cross-compilation won't be an issue since the previous versions are just plain C.
If you think there is no need to do this and we can just simply update let me know and I'll send updated patch.
