That's puzzling: xterm tries to set $TERMCAP (if it is linked with a
termcap library) since termcap-based applications typically do not pay
any attention to other ways of getting the screen size.  But termcap
on Linux isn't (especially Debian) used much.

If you have an application that uses termcap, it's probably worth taking
the time to compile 'resize' linked with the termcap library as well.
(xterm's configure script tries to find a termcap library in preference
to terminfo for this reason).
