Overloaded functions in C++ (bug?)

[miguel_l@airtel.net]

I admit that I am not a C++ expert, so maybe this is not a bug. The 
problem is that declaring a function within a class prevents the compiler
from seeing other functions with the same name but different parameters,
which would otherwise be visible.

For example, I get an error for this code:

-------------------------------------------------------------------------

class A {
public:
	void f();
};

class B : public A {
public:
	void f(int);
	void g();
};

void B::g() {
	f();
}


$ g++ -O2 -c p3.cpp -o p3.o
p3.cpp: In method `void B::g()':
p3.cpp:13: no matching function for call to `B::f ()'
p3.cpp:8: candidates are: void B::f(int)

-------------------------------------------------------------------------

And for this code:

-------------------------------------------------------------------------

void f();

class B {
public:
	void f(int);
	void g();
};

void B::g() {
	f();
}


$ g++ -O2 -c p4.cpp -o p4.o
p4.cpp: In method `void B::g()':
p4.cpp:10: no matching function for call to `B::f ()'
p4.cpp:5: candidates are: void B::f(int)

-------------------------------------------------------------------------

I'm using gcc version 2.95.2:

-------------------------------------------------------------------------

$ g++ -v
Reading specs from /usr/local/lib/gcc-lib/i686-redhat-linux/2.95.2/specs
gcc version 2.95.2 19991024 (release)

-------------------------------------------------------------------------


Yes, I know that I could work around by using `A::f()' in the first
example and `::f()' in the second one. But I'd like to know whether
current gcc behaviour is according to the standard or this is a genuine
bug. I've read the FAQ, but I haven't found any reference to this kind
of problem.

I'm not subscribed to the gcc-bugs mailing list. I'll search the list
archive for replies, but I'd appreciate if you cc'd them to me. Thanks in
advance.
