Thanks for the patch!  Have you tested it with both GCC and clang?

It might be worthwhile to break this up into distinct PRs:
1. enable most warnings that dont require any fixes today.
2. for each new warning enabled that requires source fixes, submit a distinct PR

It looks like most of the fixes are -Wunused and -Wconversion?
