Even more concise! Except your names are longer ;-)

I've arrived at nearly the same testcase. I was able to omit the C
linkage stuff. Filed as STDCXX-939.

Cool. FYI, I played with it a little and here's what I reduced
it to:
extern "C" typedef void F (int);
extern "C" void bar (int) { }
int main () {
F* const f = (F*)-2;
return f == bar;
}
I sent the test case to HP.

It believe it is. I'm filing an external bug right now for that.

I haven't looked at it very closely -- is this a compiler bug?
