Subject: [PATCH] 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.
