[RFC,03/12] Makefile: [HACK] Work around GCC 8 warnings :(

Commit Message

Dave Martin Jan. 18, 2019, 4:14 p.m. UTC

Some of these are relatively harmless lazy coding issues; others
are overzealousness on the part of the compiler (in some cases, the
code is provably safe, yet GCC warns anyway).

Turning the warnings off locally is not nice, but better than
turning them off globally.
