Anyone see a problem in 5.7 ncurses Ada?

[localhost@example.org]

I had built some programs against an earlier version of ncurses, I can't
remember whether it was 5.5 or later and they were working fine. When I
rebuilt them against 5.7 a few of them broke. I have tracked it down to
incorrect values being returned by get_size. For a 24x80 xterm get_size is
returning 25 columns and 81 lines. This makes the values actually 2 higher
than they should be, because the numbers are supposed to be
zero-relative. That is the lines should be 23 and the columns 79. Has anyone
else noticed this? I don't know whether it's in the Ada binding or in
ncurses itself. I would think if ncurses itself was broken people would have
noted and fixed it but then again I don't think the Ada binding has been
touched in years (and wow, it's good).
