Multiple local functions are defined in the global namespace without the static keyword. This compiles fine for now, but will cause a missing declaration warning when we enable them. To prepare for that, move the function declaration to an anonymous namespace. While at it, for consistency, include an existing static function in the namespace and drop the static keyword.
