warn about function without & or arguments?

[Matthew Woehlke <mw_triad@xxxxxxxxxxxxxxxxxxxxx>]

If I have e.g.

typedef void (* fp)();

void foo() { ...}
void bar(fp f) { ... }

int main() {
  bar(foo); // <-- should generate a warning!
}

...is there a warning flag (for C) in either gcc 3.4.4 or 4.x to warn 
about using 'foo' (as opposed to 'foo()' or '&foo')?
