I suspect that there is some PCH involvement here.  In particular, the warnings
you're seeing while compiling header_cassert are very surprising, in that the
preprocessed source for that file does not contain the string "_S_do_it".  So, I
think the problem is related to PCH.  To fix that, I'll need a test case that I
can reproduce in a cross environment; i.e., preprocessed source that I can turn
into a PCH, and then some use of the PCH that produces the warnings.

In any case, I'm going to test, and then check in, the latest patch, as lots of
link-time warnings is better than link failures.
