class A {};
class B {
static A *A;
};
A *B::A = 0;
g++3.4-20040317 compiles code without errors.
g++3.3 reports error: declaration of `A*B::A' changes meaning of `A' from
`class A'
which behavior is correct?

The code is ill-formed. No diagnostic is required. GCC used to diagnose that in the past. This is a regression.
