That's good, as there is no error in your example. Fact is, 
	foo;
is an entirely valid C statement with a different meaning from
	foo();
The first statement will evaluate to the address of foo(), which will
then be thrown away (as you haven't told the compiler to do anything
with it). A warning might be appropriate in this case, but it's
certainly not an error.
