[PATCH 2/2]: Fix clean compile on AIX 5.3

[Chris January <chris.january@allinea.com>]

AIX curses doesn't define 'clear'. It should be #define clear()
wclear(stdscr), but this is missing from the headers. It can be worked
around by using erase and clearok, or maybe there is a better way?

2012-03-12  Chris January  <chris.january@allinea.com>

        * tui-tui.win.c (tui_resize_all): Use erase and clearok instead 
        of clear.
