        special when skipping.  Handle * \ newline / correctly in comments
        when skipping.
        (skip_quoted_string): After \ newline, set *backslash_newlines_p
        even if count_newlines is 0.
        (macroexpand): Newline space is not a special marker inside a string.
        (macroexpand, macarg): Do not generate \ddd for control characters
        when stringifying; the C Standard does not allow this.
        (macarg1): New arg MACRO.  All callers changed.
        Do not treat /*, //, or backslash-newline specially when processing
        the output of a macro.
        (discard_comments): Don't go past limit if looking for end of comment.
        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.

        * i386/x-sco5 (CC): Remove trailing white space.
        * x-convex (CCLIBFLAGS): Likewise.
        * arm/t-semi (LIBGCC2_CFLAGS): Likewise.

        * Version 2.8.0 released.

Wed Jan  7 17:54:41 1998  J. Kean Johnston  <jkj@sco.com>

        * i386/sco5.h ({END,START}FILE_SPEC): Link with correct crtbegin.o
        and crtend.o when using -static.

        * cppexp.c (gansidecl.h): Include.

Wed Jan  7 17:45:07 1998  Tristan Gingold  <gingold@puccini.enst.fr>

        * expr.c (get_push_address): Use copy_to_reg instead of force_operand.
        (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  <Christian.Iseli@lslsun.epfl.ch>

        * combine.c (force_to_mode): Return if operand is a CLOBBER.

        * 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  <wilson@cygnus.com>

        * cse.c (max_insn_uid): New variable.
