Yes, I will re-add -O to my flags. When I did it I forgot it would
affect warnings. In fact, I am now seeing a similar warning in python
that I hadn't seen before, and others probably don't see it because they
don't compile python.
FYI, -O2 adds only 2 minutes to my 13 minute test script (but increases
the cpu usage from 4 to 6 minutes).
