Ok, sorry to report a dupe.  I really tried to search the bug db first, but I guess you had already closed the original bug.  (My boss wont let me close a bug until the software is available to the customer, so I just assumed if there were a previously reported bug, it would not be in the Closed state.  Live and learn.)

Any other Unix-ism's lurking out there in the code?  Perhaps track down the contributor who added this code, and see what other changes he/she made, since this person seems to have a blind spot when it comes to supporting Windows.
