No, I meant tui_rehighlight_all from the original patch.  See below.

I added tui_active to the condition.

Here's what I pushed:

commit 6cdb25f4df143e8d98bd71bf943bbe61c702e239
Author: Eli Zaretskii <eliz@gnu.org>
Date:   Fri Jan 16 18:24:16 2015 +0200

    Make setting TUI border attributes take effect immediately
    
    gdb/
    2015-01-16  Eli Zaretskii  <eliz@gnu.org>
    
         * tui/tui-win.c (tui_rehighlight_all, tui_set_var_cmd): New
         functions.
         (_initialize_tui_win) <border-kind, border-mode>:
         <active-border-mode>: Use tui_set_var_cmd as the "set" function.
         * tui/tui-win.h: Add prototype for tui_rehighlight_all.

Hi Eli,

This patch does not compile on x86_64 with --enable-targets=all.  You
can see the failures here:

Sorry, should be fixed now.
