A _lot_ has changed since 2.03: _open now works differently, fstat
uses system calls it didn't before, there's symlink support whcih
wasn't there in v2.03... (probably forgetting some more)

But I'm actually more bothered by your saying that _get_dev_info
returns zero for redirected stdin.  I thought you tested that several
days ago and found preconnected handles to be in good shape as far as
IOCTL calls were concerned, no?  If that's not true, we might have
problems with isatty which is used _very_ heavily in many
applications.
