More precisely a back-end notion of "static", not a real C static.
That is, that notion of static should *never be seen by the C++

struct S { };
static void f(S) { }
template<class T>
void g(T t) { f(t); }
int main()
{
S s;
g(s); // ERROR -- no f() can be found in instantiation
}
Oh yes, GCC does not get it right but we know it should be fixed.
(and notice, no "export" was involved :-))
