No. It treats a leading double slash as a single slash, despite the Posix
permission to do otherwise, and treats a non-leading double slash as an
error, despite the Posix requirement not to do that. (I have reported
this bug to Feedback Hub.) Thus, even though "cat ./dogs" works,
"cat .//dogs" returns ENOENT.

Actually, it does do privilege separation independent of Windows.
I added cowan as a user with useradd -m, and I just do "su - cowan" by
hand as the first thing when the initial bash starts up. All is well;
I get EPERM when I try to write into /bin.

If you have ever wondered if you are in hell, it has been said, then
you are on a well-traveled road of spiritual inquiry. If you are
absolutely sure you are in hell, however, then you must be on the Cross
Bronx Expressway. --Alan Feuer, New York Times, 2002-09-20
