Thank you.  I've tried this, and the -L1 argument is needed
with xargs.  But even with that, the pathnames get screwed
up for subdirectories ...

  $ pwd
  /home/me
  $ cygpath -w `pwd`
  e:\home\me
  $ find . -type f -print | cygpath -w -f- | xargs -L1 attrib
  A          E:\home\me\.bash_history
  A          E:\home\me\.cvspass
  File not found - .elinksbookmarks
  File not found - .elinkscookies
  File not found - .elinkselinks.conf
  File not found - .elinksglobhist
  File not found - .elinksgotohist
  A          E:\home\me\.emacs
  File not found - .fluxboxfbrun_history
  ... etc. ...

Because of cygpath, filenames such as .elinks/bookmarks and
.fluxbox/fbrun_history are passed to xargs like this:
.elinks\bookmarks and .fluxbox\fbrun_history.

Then xargs invokes attrib via a subshell, and therefore,
shell meta-character handling is performed. That causes
the backslashes in those path names to be removed before
they get passed to the attrib command, thereby causing
that program to see incorrect file names.

Because of this, a hacky wrapper script for attrib like the
one I wrote in my earlier message is still needed, unfortunately.
