rsh is using getopt_long for option processing.  The old versions had it
statically linked in while newer versions are using the getopt_long built
into Cygwin.  By default, Cygwin's getopt_long has argument permutation
switched oon, so that explains it.  For now, add the environment variable
POSIXLY_CORRECT before calling rsh or, even simpler, quote the remote
command:

  rsh server 'ls -a'

The next version of inetutils will have argument permutation switched
off for short option processing.
