Well, I think we should aim for zero warnings and -Werror (failing that, a
few hard-to-fix warnings and -Wno-error=whatever on selected files, with
appropriate comments e.g. referring to compiler warning bugs), and having
a few files in a different dialect of C that allows non-standard aliasing
seems bound to be confusing.
