This is a repsonse to the build errors I noticed with
build-macosx64-hybrid/plain, build-win64-hybrid/plain, and
build-linux64-hybrid/plain.
I'm not exactly sure why those build had errors but others didn't, but
my guess is that it was a combination of:
- A clang++ producing different warnings/errors.
- The uniffied builds being arranged slightly differently, which
surfaced errors based on missing include statements.
