>Description:
A member "using" declaration fails to override an inherited matching name.
As a result, in the example below, the compiler reports a type error.

The access-adjustment ("private:") adds a further wrinkle.  According
to the current standard, it should be ignored, and seems to be now, but
if the using-declaration really becomes enough of a declaration to hide
the inherited ``void i()'', it had better not become enough of a 
declaration to be private, too.

>How-To-Repeat:
$ cat /tmp/a.cc
struct Baser { enum { j, i }; };
struct Base : Baser { static void j() {} static void i() {} };
struct Derv : Base  {
  using Baser::j;
private:
  using Baser::i;
};
int k = Derv::j;
int l = Derv::i;

$ g++ -v -c /tmp/a.cc
