Near the top of the page, in the paragraph beginning "you can request" it says:

"Each of these specific warning options also has a negative form beginning
`-Wno-' to turn off warnings; for example, -Wno-implicit. This manual lists
only one of the two forms, whichever is not the default."

It would be a waste of time to say it on every option.

It's closed :-)
