I tried to check this list against c.opt - I figure this should contain essentially the ones that are have an EnabledBy(Wall), plus whatever logic there is in c-opts.

I don't see this one as enabled by Wall, and 2015-10-02 Marek Polacek <pola...@redhat.com> * c.opt (Wduplicated-cond): Don't enable by -Wall anymore.
+-Wplacement-new @r{(only for C++)} @gol
This one appears to be on by default?
+In C++, this warning is also enabled by @option{-Wall}. In C, it is also +enabled by @option{-Wextra}; to get the other warnings of @option{-Wextra} +without this warning, use @option{-Wextra -Wno-sign-compare}.
Is the last part of the sentence really necessary? It kind of follows from the rest of the documentation and we don't spell this out for other -Wextra options.
