Why won't the following code compile?

=========================================

#include <stdio.h>

class Base {
public:
	virtual void Wibble( int i ) = 0;
	void Wibble( int *i ) {
		Wibble( *i );
	};
};

class Derived : public Base {
public:
	void Wibble( int i ) {
		printf( "%d ", i );
	} 
};

int main( int argc, char *argv[] ) {
	Derived der;
	int i = 10;
	der.Wibble( &i );
	return 0;
}

=========================================

I get two errors:
error: initializing argument 1 of 'virtual void Derived::Wibble(int)'
error: invalid conversion from 'int*' to 'int'

So it looks like the Derived class has not inherited the second overload of Wibble. Why not?

Two things fix it:
1) Rename the second overload to something like WibbleWobble. Then the compiler can find it OK.
2) An overload that does not involve a pointer seems to work OK. For example Wibble( float f )

Is there a switch I need to throw to make overloading work properly? Otherwise it looks like the compiler cannot cope 
with overloads involving pointers.

I am using Momentics 6.3.2 with GNU Compiler Collection (3.3.5).
