It's hard to say if all the plumbing is needed, but no idea how to make it better.

Ugh, it'd be better to avoid casting away const... Quick solution would be to make a mutable local copy:

struct programmer_cfg mut_cfg = *cfg;

Then use `&mut_cfg` as argument instead of `(struct programmer_cfg *)cfg`.
