Yes, I think this is broken as well. However, the error is a little more specific than your example illustrates.
Take the example from Stroustrup, C++ Prog. Lang. SE, on page 377. In the example in the book, D1::h will give an error, since its throwspec is less restrictive. WS6U2 agrees.
Note, however, that WS6U2 does not give an error on D1::g, which has a more restricted throwspec than B::g. So the compiler isn't completely wrong. Now add the following to the end:
class D2 : public B
public:
void f() throw(X);
void g() throw();
void h() throw(X, Y);
Adding D2, and building, we get errors, correctly, for both D1::h and D2::h, since they are less restrictive. However, we also get an error on D2::g, claiming that its throwspec must be at least as restrictive, etc. So, it looks as if the compiler doesn't believe that an empty throwspec is more restrictive!.
You can work around this by passing -features=extensions, and these errors will become warnings. While this workaround may help, -features=extensions enables other things as well, which you may not want. But, OTOH, at least you can compile...
Hope this helps.
