invalid explicit template_or_generic argument(s) for 'template'

Function template candidates with explicit template or generic arguments resulted in disallowed function types.

The following sample generates C2770:

// C2770.cpp
#include <stdio.h>
template <class T>
int f(typename T::B*);   // expects type with member B

struct Err {};

int main() {
   f<int>(0);   // C2770 int has no B
   // try the following line instead
   f<OK>(0);
}
