Thanks for the offer.  Can you please send the output of the tiny tool I
mailed in http://sourceware.org/ml/cygwin/2006-01/msg00818.html?

Other than that, yes, a bit of comparison between d_ino and st_ino of
would be helpful.  You could use the tool I posted in
http://sourceware.org/ml/cygwin/2006-04/msg00314.html.  Just keep in
mind that it has to be build using the sys/dirent.h header from the
snapshots.

Another important factor is, if the underlying filesystem tends to
change the inode number between subsequent calls.  You can either
compare the inode numbers using the above tool, or you can see if
you encounter the dreaded "cp: skipping file 'foo', as it was replaced
while being copied" problem.

The whole 64 bit inode number is important.


Thanks,
