POSIX states that "Users should not need to set this variable in the
environment unless there is a specific reason to override the
implementation's default behavior, such as to display data in an area
arbitrarily smaller than the terminal or window."  But if it is causing
you problems, you can simply do:

export LINES COLUMNS

before invoking your app that does not know how to query the terminal for
its normal size.
