This reports a bug in g++ version 2.3.1 and 2.3.3.

If a derived class has a method that has the same name as a private member in
its base class then g++ does not allow access to the public method. Example:
------------------------------------------------------------------------------
class base
{
private:
   char *hello;
};

class derived: public base
{
public:
   char *hello() {return "hello, world!";}
};

main()
{
   derived thing;
   thing.hello();
}
------------------------------------------------------------------------------
Compiling this code gives:

   % g++ -v
   Reading specs from /usr/local/lib/gcc-lib/hp700-hpux/2.3.3/specs
   gcc version 2.3.3
   % g++ test.C
   test.C: In function `int  main ()':
   test.C:16: member `hello' is private

Cfront does not complain, but then again: ``Lang leve GNU!''
