f544dd4ab2 deal with warnings 
@levnach - there are some additional warnings.
You could revert the change to std_vector or use usize() that I added to vector.h. Look at build logs from the pipelines or actions or figure out how to add a continuous AI script to fixup build warnings (I tried a few times earlier on but the features available to do this were not for laymen).
