I can copy the condition. Much better, I can put it inside mark_used so we don't have to duplicate it everywhere.

that seems a much better approach :)

It seems that check_global_declarations, which is the one that emits
the Wunused-function warnings, is not called for functions in an
anonymous namespace. I tried finding where the decision is made
without any success. Any ideas?

sorry, nothing comes to mind. It is an orthogonal issue though, IMHO.
