It was originally just for the terminal types, which are pretty OS-depedent.

It's not necessary, but it's a nice touch.

True, this one probably should be keyed on the system type.

The first question is whether there is a different thing we can put in the
XTerm file that will work on both platforms.  If not, then that should
probably be keyed on the X windows version or the xterm version, whichever
is the deciding factor.

This should actually be done from the script which calls dialog (xt5250).  You
know, like:

if dialog --help |grep -q backtitle ; then bt_arg="--backtitle $title" ; fi

...

dialog $bt_arg ...

For reference, both dialog -h and dialog --help return text containing the
word 'backtitle' on RH7.1.

I hope this is useful...
