On: Move semantics in Rust, C++, and Hylo

-Wno-foo is turning off those warnings, not turning them on.

Wow, thanks. The gcc documentation appears to have a problem.

It lists -Wreorder as a warning, and says it's enabled by -Wall . It lists -Wno-pessimizing-move as a warning, and says it's enabled by -Wall .

I think the documentation should be edited to not list -Wno-pessimizing-move , and instead list -Wpessimizing-move .
