Compiler Error C2694

'override': overriding virtual function has less restrictive exception specification than base class virtual member function 'base'

A virtual function was overridden, but under /Za, the overriding function had a less restrictive exception specification.

The following sample generates C2694:

// C2694.cpp
// compile with: /Za /c
class MyBase {
   virtual void f(void) throw(int) {

class Derived : public MyBase {
   void f(void) throw(...) {}   // C2694
   void f2(void) throw(int) {}   // OK
