[Bug c++/20293] [3.4/4.0/4.1 regression] Wrong diagnostic for ambiguous access

This is indeed a diagnostic problem: the access is ambiguous, but instead 
of saying so gcc chooses to mention that there is no such name at all. This 
happens in many places, and I believe that there must be at least half 
a dozen PRs about this. 
 
This is in fact also a regression, since before the new parser we got this: 
 
g/x> /home/bangerth/bin/gcc-3.3*/bin/c++ -c x.cc 
x.cc: In function `int main()': 
x.cc:16: error: use of `hide' is ambiguous 
x.cc:1: error:   first declared as `hide' here 
x.cc:7: error:   also declared as `<unnamed>::hide' here 
x.cc:16: error: parse error before `::' token 
 
icc says this: 
g/x> icc -c x.cc 
x.cc(16): error: "hide" is ambiguous 
      F(hide::j); 
        ^ 
 
compilation aborted for x.cc (code 2)
