private inheritance and public members

[Stéphane Ninin]

Hello,

I have this piece of code:

class A {
public:
virtual void test(const A*);
};

class B : private A {
public:
virtual void test(const A*);
};

class C : B {
public:
virtual void test(const A*);
};


Depending on the compiler I use, code compiles fine or
compiler tells me:
test.cpp:1: error: `class A' is inaccessible
test.cpp:14: error: within this context

I guess the code is incorrect, but am not completely sure.

Any ideas / comments on this ?


Thanks.

I have this piece of code:

class A {
public:
virtual void test(const A*);
};

class B : private A {
public:
virtual void test(const A*);
};

class C : B {
public:
virtual void test(const A*);

Write it as

virtual void test(const ::A*);

};

Well, name lookup is a funky thing. Some find 'A' in the
namespace, some find it in the B (as B::A). The compilers that
don't complain are probably in error. IOW, they all _should_
complain.
