Rsync may set bogus permissions if --perms is not specified and ACLs

For some (security?) reason rsync (without --perms) does not rely on
permissions set by open(., O_CREAT, .). The permissions are set later
based on the default ACL of the parent dir.
The problem is that the rsync function acls.c:rsync_acl_get_perms()
expects that the default ACL has an "other" entry and that the "mask"
entry has only 3 rwx-bits.
The default ACL returned by Cygwin does not contain an "other" entry
in this case. The default "mask" is 0777 (OK or Cygwin bug?):
The ACL issues are now fixed in Cygwin CVS. The rsync problem should no
longer occur with future cygwin1.dll releases.
