Pages of warnings is not ideal, though. We should either support
"SH_SCOPE static", or have some kind of useful #error that makes it
clear that we don't support it (and/or don't think it's a good idea).

In a simple "hello world" test with an unreferenced static function, it
doesn't seem to be a problem at -O2. I suppose it could be with some
compiler somewhere, or perhaps in a more complex scenario, but it would
seem strange to me.
