My feeling is that we shouldn't do this in upstream clang. The vast
majority of our default-error warnings are actually checks for invalid code
that we want to be able to accept in system headers. To my knowledge, none
of our existing default-error warnings fire on well-formed code, which this
is.

I think it's totally reasonable for vendors to want to make this default to
an error, though. :)
