That's from back when the c++ standard was a rough suggestion. I had to use code warrior 10 for a project back in 2008ish (when standards compliance seemed to actually be picking up real steam across gcc/llvm/msvc) and it was painful how many things that were standard/supported across the other compilers that would break, we ended up basically falling back to closer to c with classes than anything that would resemble modern (at the time) c++.
