It should occur on NT4 also. The inheritance set by the current
Cygwin itself should not result in problems unless somebody tries

Not really. setup.exe doesn't handle permissions at all.
Charles Wilson has written a small perl script which can do that
but I'm not sure how that will go into the next version.
It hasn't been discussed yet.
