Python has:
typedef void (*freefunc)(void *);
That looks weird to me, but I'm not a language guy.

That solves my problem. I was assuming this should get sorted out before release so other users don't get confused.
There are 24 warnings, 535 lines. Here is everything from the last one.

Looking closer, there are 12 repeated pairs.
