Maybe then try with one function (to see whether it has an effect)
and then revert that change again.

To save work. (It's not needed. If for some reason a previously
unused function is needed again then SDCC will compile the code
dependent on the previously unused function but fail at the
linking stage.
Fair enough and will give a good hint at where the problem is.)
