Purely guessing, but the "unstable tooling" could perhaps refer to the fact that C++ as a language has evolved a lot. I have had trouble compiling older C++ code bases with newer compilers, even when specifying C++98 as source standard. I gave up trying to get Scott McPeak's Elkhound C++ parser to compile, last I had to attempt it. C is a bit more forgiving on that topic (it hasn't changed as much, for better or worse).
