Thanks.  I get the expected result on my system, with the latest
pretest binary.  The only differences I could think of that could
explain why we get different results are (1) I built the pretest
myself (will try the binary you used later); and (2) some Windows
configuration changes, either on your system or on mine, that make our
systems behave differently.

Would other Windows users please try reproducing this problem on their
machines?
