It's been consistent over many days of testing and the only difference
between release and snapshot, so I thought I'd mention it.

Not that I can see, it simply seems to call stat64, which it did before.  I
don't think it drops any groups, either.  And again, just mounting cygdrive
with "noacl" gets rid of the problem entirely.

I think yes, I hadn't moved it away (but no passwd file).

I've just updated to the latest snapshot w/o AD integration for testing,
will revert to the other one for more testing.  Not sure if I can fit that
in today, will send the links via PM when I have the traces uploaded.
