Bernard, I fucked it up with this #3: (changed macro to function at
the last minute). I'm currently reading this, and maybe I'll figure
out something, but if it's not a big problem for you to repeat this
after adding this #4 (after all previous) it should be 'a bit' easier.
(But no need to hurry.)

Very sorry,
