c++/9328: [3.2/3.3/3.4 regression] ICE with templates and namespace std members

[Zeisel Helmut VAI.ATI 3]

In the meanwhile I found that this ICE has nothing to do with templates and namespaces,
but is a problem of typeof(X) when the type of X cannot be uniquely derived.
The same ICE occurs in the following code:

double f(double);
float f(float);
void h(typeof(f) g) {}
