bug#13702: 24.3.50; dired-do-rename: Mysterious error "(file-error Getting ACL no such file or directory <existing file>)"

[Paul Eggert]

Many other error numbers should be checked for.
Here's what Gnulib's acl-internal.h says on the subject, right now:

/* Recognize some common errors such as from an NFS mount that does
   not support ACLs, even when local drives do.  */
#if defined __APPLE__ && defined __MACH__ /* Mac OS X */
# define ACL_NOT_WELL_SUPPORTED(Err) \
     ((Err) == ENOTSUP || (Err) == ENOSYS || (Err) == EINVAL || (Err) == EBUSY 
|| (Err) == ENOENT)
#elif defined EOPNOTSUPP /* Tru64 NFS */
# define ACL_NOT_WELL_SUPPORTED(Err) \
     ((Err) == ENOTSUP || (Err) == ENOSYS || (Err) == EINVAL || (Err) == EBUSY 
|| (Err) == EOPNOTSUPP)
#else
# define ACL_NOT_WELL_SUPPORTED(Err) \
     ((Err) == ENOTSUP || (Err) == ENOSYS || (Err) == EINVAL || (Err) == EBUSY)
#endif


Maybe Emacs should steal this macro.  Or we can change Gnulib
to publish it and then use the relevant Gnulib module.
