errno related question

[Ishav]

I compiled and run the following program using
glibc-3.2.1 (on RedHat 8.1) with non-TLS support 
(by setting the LD_ASSUME_KERNEL=2.2.5).
All the functions except stat() is calling the local
__errno_location(). Why the stat() is not calling it?
I know this doesnt work with TLS support, but for
non-TLS, it should work same as glibc-2.2.x.

Thanks,
ishav

=============
#include <sys/stat.h>
#include <errno.h>
int myerrno = 0;
int *__errno_location(){return &myerrno;}
main()
{
        struct stat stbuf;
        close(555);
        printf("myerrno=%d\n", myerrno);
        errno = 1;
        printf("myerrno=%d\n", myerrno);
        stat("nofile", &stbuf);
        printf("myerrno=%d\n", myerrno);
        read(5, &stbuf, sizeof(struct stat));
        printf("myerrno=%d\n", myerrno);
        kill(50000, 1);
        printf("myerrno=%d\n", myerrno);
}
