[Voted into WP at October 2004 meeting.]

Proposed resolution:

Change the example at the end of 11.4.10 [class.bit]/4 from:

  enum BOOL { f=0, t=1 };
  struct A {
    BOOL b:1;
  };
  A a;
  void f() {
    a.b = t;
    if (a.b == t) // shall yield true
    { /* ... */ }
  }

To:

  enum BOOL { FALSE=0, TRUE=1 };
  struct A {
    BOOL b:1;
  };
  A a;
  void f() {
    a.b = TRUE;
    if (a.b == TRUE) // shall yield true
    { /* ... */ }
  }

It looks like the example on 11.4.10 [class.bit] paragraph 4 has both the enum and function contributing the identifier "f" for the same scope.

  enum BOOL { f=0, t=1 };
  struct A {
    BOOL b:1;
  };
  A a;
  void f() {
    a.b = t;
    if (a.b == t) // shall yield true
    { /* ... */ }
  }
