Hmmm...I've been thinking. I'm not sure you *want* to store NTSD
descriptors in a zip file. Suppose I have SID 1-3661234856-525, and zip
up my files, and give the zip to you. Then, you unzip the file but there
is no user #525 on your machine. What happens?

When you get right down to it, cygwin is NOT windows. It does everything
it can to make windows look like Unix, so that apps can run *as if they
were on unix* with little or no changes. So, by that logic,
cygwin-zip/unzip =should= be built as unix-ish apps, not windows-ish
ones.

Comments?
