Irrelevant, we all know what he's talking about, and whether it's gcc, llvm or icc, his point stands.

I don't see the distinction. C is a language for describing what operations the program will perform. The compiler (gcc) / runtime (llvm) then turns that description of the solution to the problem into something the computer can actually execute. Sometimes it uses JIT compliation... other times, perhaps not.

If you "use C for control", then you must have written your own compiler.
