[dropping cygwin-patches, since posts are closed to non-subscribers, and
adding bug-findutils and bug-gnulib.  Christian is working on a patch that
lets cygwin do initial support of dirent.d_type]

According to Christian Franke on 11/27/2008 2:41 PM:

This seems like it might be a bug in gnulib's fts implementation.  How
does 'oldfind /path -type d' perform?  oldfind has the advantage of not
using fts, so if it performs better, then there is a hole where we need to
improve gnulib's fts to make directory-only or non-directory-only
traversals use d_type for optimization.
