pointer member constant expression

[Perry Smith]

I have asked this question before -- maybe to the gcc-help list but  
I'm still unclear.

The problem is this:
struct foo {
    int a;
    int b;
    int c;
};

static const int foo::*j = &foo::c;                 // accepted

class dog {
    static const int foo::*k = &foo::c;     // error
};

5.19 (constant expressions) paragraph 2, the last item in the 1998 C+ 
+ spec says " -- a pointer to member constant expression."  That  
appears to be defined as: '&' qualified-id (5.19 paragraph 6).

So is the line in error legal C++ or not?

Thanks,
Perry
