gcc46-pr43728.patch
Updated patch. There are still cases I'm unsure about. E.g. for:
static void g ();
void

Presumably TREE_USED isn't set on the global declaration because the call uses
the local one. And the local declaration might not be redundant if the
programmer is using it to suppress argument-dependent lookup.

Quick patch, so far without documentation and testsuite and almost untested.

If you are going to add such a warning, please be more explicit. I suggest:
redundant prototype for static function %qD because it is never used before
its definition

...and then after removing the prototype, compiling with -DD would fail. I
don't object to having such a flag, but I don't think we want it in -Wall.

-Wredundant-decls is a non-default warning already, not enabled with -Wall nor
-W and I certainly don't want to enable it by default.
