It invents inodes on Windows '98 SE. Maybe _ioctl_get_first_cluster can get an
inode on Win2k/XP, but doesn't return consistent results? That would be weird,
but it seems possible.

Yes, that is true.

I think someone with Win2k/XP needs to investigate this more. The original
e-mail is linked from the DJGPP 2.04 status page:

http://www.phekda.freeserve.co.uk/richdawe/djgpp/2.04/status204.html

Here's the link for convenience:

I'd do it myself, but I don't have Win2k/XP.

Bye, Rich =]
