I don't think there has been a discussion around -Wstring-compare
before. Unfortunately, it seems like clang's -Wstring-compare is
different from GCC's -Wstring-compare. clang's is basically a subwarning
in GCC's -Waddress and GCC's -Wstring-compare does not really have an
equivalent in clang proper (it seems like it might be a clang-tidy
check IIUC?):

So if we want to disable -Wstring-compare, we should only do it for GCC
in my opinion.
