BTW, I also see that in c-family/c.opt -Wpointer-arith is not LangEnabledBy(C
ObjC C++ ObjC++,Wpedantic). If it was, then -Werror=pedantic will automatically
handle -Werror=pointer-arith (and the same when using #pragma GCC diagnostic).
So, this is one of the bugs that prevent -pedantic-errors == -Werror=pedantic.
