[readline] TUI size computation for mingw32 hosts

Attached is a patch that fix a problem of calculating console window size
when gdb is hosted on windows.

I already fixed this problem in gdb 6.4 version, that was integrated into
readline (cf 
http://sources.redhat.com/ml/gdb-patches/2006-02/msg00245.html)
, but the readline I got from the 6.5 version cancels the modification 
with some new
code that overwrote variables I used.

	* readline/terminal.c (_rl_get_screen_size): use wr and wc variable to store
	window size.
