Can you tell us what compiler and version, and what system?
Any arguments to configure?
And how did you get the Tor source code?

I don't know why we didn't catch these warnings earlier.

This is spurious, but I'm not surprised the compiler can't tell.
We should fix it.

These are annoying, and can sometimes be bugs.

Please tell us about your system, we thought we had caught most of
these warnings.

As above.

We turn off this warning, why does your compiler report it?
