In practice, LLVM (more specifically Clang) has been including more
and more GCC flags, just because everybody wants warning-free and
nobody wants configure-hell. :-)

Clang warnings have been catching cases that GCC misses (quite a few
in the Google codebase, in fact), so it seems worthwhile to collect
and check those, at least periodically.
