Well, I've attached a patch for this bug. However, it uncovered another
problem with 'cp -p src dest', when src is not owned by the current user.
(AROUND LINE 1170 in fileutils/src/copy.c):
/* Permissions of newly-created regular files were set upon `open' in
copy_reg. But don't return early if there were any special bits and
we had to run chown, because the chown must have reset those bits. */
if ((new_dst && copied_as_regular)
&& !(ran_chown && (src_mode & ~S_IRWXUGO)))
return delayed_fail;
if ((x->preserve_chmod_bits || new_dst)
&& (x->copy_as_regular || S_ISREG (src_type) || S_ISDIR (src_type)))
{
if (chmod (dst_path, get_dest_mode (x, src_mode))) <<<<< HERE
{
#ifdef __CYGWIN__
char *p;
The chmod command returns with ENOENT. I have no idea why; the file has
already been created at this point...
