Just as an FYI, this particular change causes a slew of clang warnings:
https://travis-ci.com/ClangBuiltLinux/continuous-integration/jobs/201754420#L2435

I am not sure how exactly you'd like this resolved so I didn't want to
provide a useless patch. I figured I would let you know about it and
leave it up to you.

Cheers,
Nathan
