 Did you use the warning flags?
 
 $ /opt/gcc/3.2-devel/bin/gcc t.c -Wall
 t.c: In function `foo':
 t.c:1: warning: control reaches end of non-void function
 $ /opt/gcc/3.2-devel/bin/g++ t.c -Wall
 t.c: In function `int foo()':
 t.c:1: warning: control reaches end of non-void function
 
 This looks correct to me,
 
 Andreas

 Source file consisting of the following two lines:
 
 	int foo(void)  { }
 	int main(void) { return foo(); }
 
 Gives no warning.
