Like... what? Inode information? Looking at the man page for 'stat' (on 
Linux, anyway; apparently I don't have the libc man pages installed on 
Cygwin), I don't see anything that I would expect to need to *open* the 
file to retrieve.

Way way back in the OP, I mentioned that Interix doesn't have this 
problem, which would imply a "design flaw" in Cygwin. Maybe (probably) 
it is a *necessary* design flaw, BUT...

A while back I was thinking about tying Cygwin into the Interix 
subsystem for the sake of certain file-system calls... and things like 
fstat in particular. If the problem is that Cygwin's fstat 
implementation requires opening the file and Interix's does not, this 
just became a *very* compelling (for me, at least) argument to taking on 
that project.

Please note that I'm not asking anyone to do this... given the response 
I got last time, I don't have any illusions that this will happen short 
of my doing it myself (at which point I will be derided, and my work 
will never leave my office). However, I would appreciate any existing 
knowledge, or even pointers to where to start poking around, that anyone 
would care to share.
