        of an unterminated string constant.
        Don't mishandle backslash-newlines that in are the output of

        macro name and '(', as well as backslash-newlines in comments there.

        when stringifying; the C Standard does not allow this.

        the output of a macro.

        Discard backslash-newline properly when discarding comments.
        (change_newlines): \" does not end a string.
        (make_definition): Do not treat backslash-newline specially, as it
        has already been removed before we get here.
 
        * profile.c (output_func_start_profiler): Don't fflush output
        if -quiet.
        * toplev.c (rest_of_compilation): Likewise.

        (emit_push_insn): Avoid null pointer deference if aggregate has no
        types.
        (expand_expr): Avoid finite but useless recursion.
        (expand_builtin): Fix typo in calling function.
        * function.c (assign_parms): Avoid useless call to chkr_set_right.
 
Wed Jan  7 17:31:13 1998  Christian Iseli  
 
        * combine.c (force_to_mode): Return if operand is a CLOBBER.
 
Wed Jan  7 17:23:24 1998  Richard Kenner  
 
        * x-rs6000 (INSTALL): Remove.
 
        * jump.c (jump_optimize): Don't use a hard reg as an operand
        of a conditional move if small register classes.
 
Wed Jan  7 17:09:28 1998  Jim Wilson  
 
        * cse.c (max_insn_uid): New variable.
        (cse_around_loop): Use it.
