It doesn't work that way. If that were the case the rtl/unix dir would be empty. It only seems that way of the extremely trivial dumbed down subset that you use, but that is no problem with any scheme.

Going at it that way just shifts the pascal<-> C interface to users code, losing abstraction.

So is the FPC runtime library. And you casually throw that away too.
