Description:
------------
newt_get_screen_size doesn't work correctly on my AMD64 system. See the reproduce code and the actual/expected results.

On my other system (Linux mental2 2.6.21-xen0 #1 SMP Sun Jun 1 03:54:59 CEST 2008 i686 AMD Athlon(tm) XP 3000+ AuthenticAMD GNU/Linux), the size is returned correctly.

Reproduce code:
---------------
<?php
newt_init ();
newt_cls ();

newt_get_screen_size (&$rows, &$cols);

echo "Rows: $rows, Cols: $cols\n";
?>

Expected result:
----------------
Rows: 25, Cols: 80

Actual result:
--------------
Rows: 140733193388209, Cols: 140733193388082
