These values matches sizeof(struct stat) on gcc230, so should be
correct:

xry111@gcc230:~$ cat t.c
#include <stdio.h>
#include <sys/stat.h>

int main()
{
  printf("%d\n", sizeof(struct stat));
}
xry111@gcc230:~$ cc t.c -mabi=3D32 && ./a.out=20
144
xry111@gcc230:~$ cc t.c -mabi=3Dn32 && ./a.out=20
160
xry111@gcc230:~$ cc t.c -mabi=3D64 && ./a.out=20
216
