   I'm running bash 1.02 under Ultrix 3.0 on a VAX 8530 compiled with GCC 1.35.

   The "-n" option of the builtin echo doesn't seem to suppress a newline
   at the end.  However, using \c with -e does seem to suppress the
   newline.  I couldn't figure out the problem from a quick look at the
   code since -n and \c seem to do the same thing.

Yeah, sorry about that.  In builtins.c, function echo_builtin (), the
segment of code reading:

	  while (*temp)
	    {
	      if (*temp == 'n')
		display_return == 0;
    #ifdef V9_ECHO
	      else if (*temp == 'e')

should read:

	  while (*temp)
	    {
	      if (*temp == 'n')
		display_return = 0;
    #ifdef V9_ECHO
	      else if (*temp == 'e')

i.e., the test "display_return == 0" should be an assignment.
