[Bug c/36195] New: Add warnings for useless static functions prototypes in -Wredundant-decls

[eugene dot zelenko at gmail dot com]

Sometimes static function prototype declared with static function definition,
but function is never called before definition. So prototype in such cases are
definitely useless.

I think will be good idea to enhance -Wredundant-decls with reporting such
situation.

PS

May be this is already implemented in versions never then 4.1.2, but 4.3.0
manual is not mention such possibility.
