C, still?

On the other hand compiling C is fast but compiling C++ is slooow. In my experience most compilation times were in the coffee-break range, but if a common header was modified (fix documentation comments, add private fields), it was lunch-break time. Pre-compiled headers might help, but I don't know how much. And although modern C++ with all those move semantics can be really effective, it can also be really complicated...
