[Bug c++/28156] New: spurious warning: function defined but not used

["rwxr-xr-x at gmx dot de" <gcc-bugzilla at gcc dot gnu dot org>]

Hi,

$ cat try.cc
#include <iostream>

static void foo() {
    std::cout << "hello, world\n";
}

int main() {
    extern void foo();
    foo();
}

$ g++-4.1.0 -Wall try.cc
try.cc:3: warning: `void foo()' defined but not used
$ ./a.out
hello, world

foo() is clearly used there so why does g++ warn about it?
