So what?
Here's output from some gcc 2.9x:

#include <stdio.h>

void foo(void){

  long l;
  int i;

  printf("%i %li", i, i);
  printf("%i %li", l, l);

}
[E:\leer]gcc -Wall -W -c c.c
c.c: In function `foo':
c.c:8: warning: long int format, int arg (arg 3)
c.c:9: warning: int format, long int arg (arg 2)

There are indeed both kinds of warnings and my cast
to (long) is to be well justified.
