Until one of the main developers can attend to it and then upload an
updated snapshot, you might be able to get some useful information for them
by running your test under 'strace'; you'll be able to see the translation
from unix to dos path, and see what gets passed to the actual underlying O/S
CreateFile call. By comparing it between 1.5 and 1.7, you might narrow down
the cause pretty well.
Can't think of a witty .sigline today....
