Which version of find? find 4.3.0 switched over to gnulib's fts implementation, which, if openat() and friends were to be implemented, is capable of traversing directories without using chdir. Even with the current cygwin limitation of no openat(), it can still traverse almost everything using /proc/self/fd/blah; the only problem is that because cygwin still incorrectly treats /proc/self/fd/.. as /proc/self/ instead of the parent directory of the open directory fd, you can't traverse back up the tree. - -- Life is short - so eat dessert first!
