-----------
If we're going to test for switch validity by observing whether the
compiler emits any warnings, the test program had better be 100%
correct, not only 90% correct. The recent addition of -Wold-style-definition
broke thread-safety detection on every platform that has that switch,
because the test program used an old-style definition.
