I included a header in a trivial program, and preprocessing was 50%. So this kinds of benchmarks depend heavily on how your headers are organized. (the notorious "one big header per project that includes everything necessary problem".)

Still it is an interesting option, I'll see if I can compile something like binutils that way.

I still work full time with Delphi. If something usuable beats that with an untweaked setup, let me know
