	I always thought C used structure equivalence and not name 
equivalence.   In the example, both the return argument and declared
function are structurally equivalent, right?

They say there are strangers, who threaten us
In our immigrants and infidels
They say there is strangeness, too dangerous
In our theatres and bookstore shelves
Those who know what's best for us-
Must rise and save us from ourselves

Quick to judge ... Quick to anger ... Slow to understand...
Ignorance and prejudice and fear [all] Walk hand in hand.
