>Organization:
>Environment:
Win2k + mingw2.0(gcc3.2, and rc2 of gcc3.2.1);
Redhad Linux 8.0 + gcc3.2
>Description:
If a class inhereit from another class which further non-publicly inherit yet another third class. Any member or parameters that use not full qualified name of the third class will fail to compile.

"`class XXX' is inaccessible"
in which XXX is the name of the third class.

gcc 2.95-3 does not has this problem.
>How-To-Repeat:
// test.cpp, compile with "g++ -c test.cpp"
class A {};

class B : A {};

class C : public B {
public:
	A* p; // compiler report : `class A' is inaccessible
};
>Fix:
// test.cpp
class A {};

class B : A {};

class C : public B {
public:
	::A* p; // full qualified, ok
};
