where is warning: control reaches end of non-void function

Fri May 9 22:09:00 GMT 1997

To my horror the following code compiles without a warning:
int Foo()
{
}
on spark, gcc-2.7.2 produces 
warning: control reaches end of non-void function `Foo()'
am i missing something? (like an option maybe?)
TIA.
