Is this legal?

[red floyd]

class A {
public:
enum E { EN1, EN2, EN3 };
};

class B {
public:
void f(const char *s, A::E en = A::E::EN1);
};

MSVC 7.1 accepts it, G++ 3.2.2 (3.2.2-3mdk) gives the following error:
`A::E' is not an aggregate type

Is this an error in G++ or in VC? What does the Holy Standard say?

Oops. The error is in reference to the A::E::EN1 default parameter value.

Enumerators are names in the same scope where the enumeration type
is declared. I.e. to get to EN1, you say A::EN1, not A::E::EN1.

Thanks, Victor. Appreciate the help.
