Oh, btw.  In your OP you claimed that you have netapps for which Cygwin
returns "cifs" and other netapps for which Cygwin returns "vfat" as
filesystem.  The above one is clearly one of the "cifs" type.

Here's the question: Do you *really* have some for which the latest
Cygwin 1.7.7 or the latest snapshot returns "vfat" and are they *really*
netapps?  In theory I'd expect that those are just remote FAT FS on some
remote Windows machine, and they shouldn't be affected by the reported
problem.

If they are actually netapps, there's very likely no chance at all to
recognize those as netapps from Cygwin.  We only have a chance if the
combination of flags is different from the combination of flags of a
real remote FAT filesystem and consequentially we can't have unlink
react differently.

For the sake of completeness, *if* Cygwin 1.7.7 or later really returns
"vfat" for a netapp filesystem, please send the getVolInfo info for
that drive as well.
