D'oh!!!  I just realized that *of course* the entries would not be in
/etc/passwd, as you had a different mount for "/", so "/etc" would resolve
to "c:\etc", not "x:\cygwin\etc"!  Never mind, the umount should fix this
as well.

No, no, leave it be.  My mistake.

Does the above command fix the problems you've been having?  If so, great.
As to what caused this -- I'm not sure.  Perhaps looking for "setup.log"
files on your harddrive would help...  At a guess, you've tried to install
Cygwin as "Just for me" with the root in "c:\" at some point or another.
You then changed your mind, but the mount stayed around, not affecting
anyone but yourself.
