Hello.

Could someone try the following program on Windows 2000/XP and post
the results, please? I'm wondering if our stat is totally broken
on Windows 2000/XP with respect to reporting inode numbers.

If this program doesn't PASS, then I don't see how we can expect
fileutils's rm to function correctly.

I'm trying to understand the inode messages on Windows 2000/XP.
I don't have either OS, so I can't try to reproduce it. I've never
seen that error on my Windows '98 SE box.

BTW the test PASSes on Windows '98 SE.

Thanks, bye, Rich =]
