LGTM.  Requiring permission to push.

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=32 && ./a.out 
144
xry111@gcc230:~$ cc t.c -mabi=n32 && ./a.out 
160
xry111@gcc230:~$ cc t.c -mabi=64 && ./a.out 
216

Sure, I can do that, but please attach output of (git format-patch) as an attachment
to an email. The current email has a weird format I can directly apply with git am.

Cheers,
Martin

Thanks Martin! I'm sending out the output from git format-patch as an attachment to this email.
