I tried with gcc.

cat 1.c
#include <sys/types.h>
#include <stdio.h>
#include <stdlib.h>
#include <string.h>
#include <unistd.h>
#include <errno.h>
#include <sys/stat.h>
#include <fcntl.h>
#include <stdint.h>

int
main(int argc,char *argv[],char *envp[])
{
	printf ("%uz", sizeof (int));

	return (0);
}

gcc -std=c89 -Wall -pedantic 1.c

No warning.

Thanks,
Hui
