You convenientkly forgot to time the ./configure, but ok, that's not
that often necessary when changin C code.

Better touch engine/forth.h.

Me too. It's still much faster than stepping through the program in
the hope of that the next step will show up the problem.

If I know how to check for the problem automatically, I write an
assertion (in both Forth and C).
