This is a patch for upstream, so it will have to be submitted there
along with a bug report.  However, I would note that the warnings I've
looked at are all bogus, and doing stuff just to shut the compiler up
doesn't strike me as very helpful.

We might be able to define ShouldNotReachHere so that it is treated by
the compiler as __attribute__((noreturn)).  I'm not sure that this
will fix everything but IMHO it's better than a bunch of unnecessary
code.

BTW, I guess you know you can build with --disable-warnings-as-errors.

Andrew.
