First off, VOID MAIN is not legal in any standard version of C.  Even when
the language allows implementation defined extensions to the main
signature, it must still return int.

If you have a later version of language supported, you have to define
printf rather than allowing it default define as an int returning
function.

Add #include <stdio.h>
