Thanks Bob and others who responded.  FWIW, sh on Linux accepts -e and -n at
the same time, which is how we managed to run into our trouble (we do
concurrent builds on Linux and Windows).  But i'll be changing
our -e -n references to use -e and \c.

Thanks!
John

These are mutually exclusive options.  The -n makes echo emulate the old
Bourne shell behavior, -e the new.

   echo -n test
and
   echo -e 'test\c'

Are equivalent.  The other backslash sequences recognized when -e is used
had no equivalent in older shells.  You had to embed litteral characters,
where possible.

Hope this helps.
