Here is some recent regression I see on tree-ssa. I don't have a recent 
mainline checked out, so can't test whether this also happens on mainline, 
but here is what happens: 
----------------------------- 
struct X { 
    static void foo (); 
}; 
 
template <typename T> 
void foo (const T &t) { 
  t.foo(); 
} 
 
template void foo (const X &); 
------------------- 
 
deal.II/base> c++ -c -Wunused x.cc -W -Wall  
x.cc: In function `void foo(const T&) [with T = X]': 
x.cc:10:   instantiated from here 
x.cc:6: warning: unused parameter 't' 
 
This warning is clearly bogus! 
 
W.
