Maybe, I didn't look at the code. But even if it does, I can hardly
believe it matters in this context.
If you know a way of fixing it without this side effect, please
install a different change. Alternatively, you are welcome to try
convincing GCC developers to stop issuing warnings about perfectly
valid code, unless invoked with -Wall; I gave up on that a long time
ago, after being flamed into silence.
