  First of all, on many systems, the winsize structure is defined in
<sys/ioctl.h>, not in <ptem.h>.

  Second, if you're using a system that doesn't define the winsize structure
in any of its header files, the most likely explanation is that the system
doesn't *support* the SIGWINCH signal or the TIOCGWINSZ and TIOCSWINSZ
ioctl's, so defining the structure isn't going to help you.

  The programs should be written in such a way that allows you to disable the
use of the winsize stuff.  If they aren't, they should be modified so that
they are, using preprocessor symbols to determine whether the system on which
they are being compiled has winsize.
