Because most C compilers also include a C++ compiler, or that the compiler toolchain of choice for freeBSD happens to be LLVM (it was an old version of GCC before because newer version use an incompatible license, and before that I think gcc replaced pcc in the original bsd unix, the discussion to pcc with gcc is probably lost in time) that includes C and C++ compiler. I am guessing that performance of current standalone C compiler is not as good as the one produced by compiler suit. Following the conversation thread, rust also use llvm under the hood, but a customized one. Which would force the base system to have two versions of llvm.
