Hint: 'static' prevents code in other compilation units (basically, other .c
files) from referencing it directly (though they can still access it via a
function pointer variable or other similar tricks).  That does *not* mean that
other code in the *same* compilation unit can't reference the static function
in a way that requires a symbol table entry...
