code (also pasted in bug)

[class.access] p5 in C++98 has an example and says this should be well-formed.

class C {
  enum X {
    X_VALUE
  };

  friend void foo(X);
};

// BUG: C::X is not available here
void foo(C::X x) {
  // C::X is correctly available here
  C::X x2 = C::X_VALUE;
}


$ clang++ test.cc
test.cc:12:13: error: 'X' is a private member of 'C'
void foo(C::X x) {
            ^
test.cc:4:8: note: declared private here
  enum X {
       ^
1 error generated.
