In the example above main.c contained just 'return 0;' without includes.
But you are right, the following looks strange.

   0 ~>cat main.c
   #include <stdio.h>

   int main ()
   {
        puts ("Hello World!");
        return 0;
   }

   0 ~>/srv/obj-sparc64/tooldir.NetBSD-5.99.56-amd64/bin/sparc64--netbsd-gcc -c 
-o main.o main.c
