System header warning exemptions and delta debugging don't mix well

How bad is it?  Can you compile all the headers with -Wsystem-headers
and -W -Wall and see how many problems there are?

Then we can see how hard it is to fix.

Once that's done, then we can perhaps evaluate how to keep this from
regressing.
