With findutils 4.3.1-3, what does "oldfind -noleaf -type d" do?  I suspect
that the problem is due to the difference in algorithms between 4.2.27
(repeated as 4.3.x's oldfind) and 4.3.x, where find moved from a
hand-rolled traversal to fts().

Also, I suspect that there may be problems due to the link counts
associated with the various directories in the traversal.  Find tries to
make an optimization that if it is only searching for directories, then
after encountering n-2 subdirectories in a directory with link count n
(where n > 1), there is no further need to keep on using readdir().  But
if this property does not hold true on your DVD-R directory structure,
then find misses out on subdirectories that occur after the n-2 mark.  Can
you do 'ls -ldU .*/ */' in one of the directories where find is missing
out on subdirectories, so that we can check for link count issues?  It
could be a cygwin bug in handling the link count of DVD drive directories.
