You cannot get st_ino which makes sence (without cygwin1.dll).
Compile stattest.c on Windows by MSVC (cl.exe), and you will see:

----
$ ./stattest
stattest.c: 0
stattest.exe: 0
.: 0
..: 0
C:\: 0
C:\WINNT: 0
nonexist: stat failed
----

I wrote, compiled and run this code on Windows 2000 SP2 SRP1 with NTFS
partition.
