It seems that the latest gcc in subversion allows duplicate member names in
objc subclasses.  I will attach a small program that demonstrates the issue. 
Verified that the test program does not compile on 3.3, 3.4 or 4.0.

Confirmed, I am going to say this is not expected at least for now until I
found the patch which caused this.
