Ah ntsec... Since I don't run with it, I always forgot about this
permutation. I don't believe that there is anything "seriously" wrong
with ntsec -- using it just requires more administration. From monitoring
the Cygwin mailing list, I have gleaned that people who use ntsec do
a lot of chown and chmod commands after installation. See the following
for an example:

The above is an easy one and a known problem. You must upgrade your
Cygwin DLL since you are still using 1.1.8. I can tell this from the
cygcheck output below:

The above implies 1.1.x and

the above implies y.z.8

Hence, you are running 1.1.8. You can confirm this with:

$ uname -r

Upgrade to 1.3.1 (if you are bold) or to a snapshot (e.g., 20010413).
