Jonathan, Manuel, et al -
I'm putting this to bed on our side. We've re-enabled -Wall, and are moving
towards -Wextra.
I did come up with one more use case... The "unused parameter" warning.
Typically, I just comment it out:
int Foo(int /*bar*/);
However, when generating documentation from sources, that's not a good
strategy. I now see the program omits the parameter altogether from the markup.
In the case of Crypto++, which has a lot of "interface programming" aspects, it
makes for a noisy compile as objects are composed and derived. There's often no
way to avoid something being unused along the inheritance chain.
