BLD: unused function warnings in current build

[ngoldbaum]

When I build the current main branch using clang on an ARM mac, I get the following warnings:

gcc doesn't seem to notice these

[rgommers]

I've tried to fix these before, but my fix was incorrect. It doesn't seem easy all that easy to do. But yeah, it'd be great to get these cleaned up.

[seiko2plus]

I will release a patch for it
