[Bug c++/17947] New: bad warning with implicit conversion and __attribute__((deprecated))

///////////////////////////
struct Foo
{
    operator int() __attribute__((deprecated));
};

int main()
{
  Foo f;
  (int)f;
}
///////////////////////////

gives: 

warning: `operator 1' is deprecated

In real code the '1' is often a bigger number.

Confirmed, I thought I saw a bug like this before.

Yes, me too. What a funny message :-) 
 
BTW, this is how the bug evolved over time: 
 
g/x> /home/bangerth/bin/gcc-4.0-pre/bin/c++ -c x.cc 
x.cc: In function `int main()': 
x.cc:9: warning: 'operator 1' is deprecated (declared at x.cc:3) 
g/x> /home/bangerth/bin/gcc-3.4*/bin/c++ -c x.cc 
x.cc: In function `int main()': 
x.cc:9: warning: `operator 1' is deprecated (declared at x.cc:3) 
g/x> /home/bangerth/bin/gcc-3.3*/bin/c++ -c x.cc 
x.cc: In function `int main()': 
x.cc:9: warning: `operator 1' is deprecated (declared at x.cc:3) 
g/x> /home/bangerth/bin/gcc-3.2*/bin/c++ -c x.cc 
x.cc: In function `int main()': 
x.cc:9: warning: `operator i' is deprecated (declared at x.cc:3) 
g/x> /home/bangerth/bin/gcc-2*/bin/c++ -c x.cc 
x.cc:3: warning: `deprecated' attribute directive ignored 
 
I.e., something changed between 3.2 and 3.3, but it didn't become better 
or worse.
