Yet another What's-wrong-with-my-code question:

	 1  class base {
	 2  public:
	 3     int a;
	 4     void f()     {}
	 5  };
	 6
	 7  class derived: base {
	 8  public:
	 9     base::a;
	10     base::f;
	11  };
	12
	13
	14  void main()
	15  {
	16     derived x;
	17
	18     x.a = 0;
	19     x.f();
	20  }


Compiling this with CC (cfront version 1.2.1) gives the following
errors:
CC  test.c:
"test.c", line 18: error:  a is from private base class
"test.c", line 19: error:  f is from private base class
2 errors

BS says "It is possible to declare some, not all, of the public
members of a base class public memberes of a derived class."
(page 196)   Where have I gone wrong then? Could someone help me?

Thanks in advance.
