The OLIT code is the Xt+ code from release 2, modified at USL for X11R4 --
done last spring as the first stage in implementation of the new release 4
(to be generally available in mid-Dec).  It was *after* we ported to the R4
server that we started to add new functionality (3D, mouseless operation,...)
-- I suppose that these later changes will also become available with some
future update to OpenWindows.

I understand there *were* a few porting changes to fit the code with SunOS
and with OpenWindows generally, but substantially OLIT *is* the USL code.

Oddly enough, I got the same error using the latest XWIN and Xt+, the
scrollbar example was missing a definition of XtNtitle, which requires
including Shell.h; I presume this is related to header differences from 
the R3-to-R4 change.  Anyway, I recommend Miller's book for a quick
start in OPEN LOOK widgetry.  If anyone needs the reference, it is
published by M&T Books, Redwood City, CA, 1990; ISBN 1-55851-058-3
(for the book/disk combination Chris mentions; the book and the disk are
also available separately (~057-5 for the book, ~059-1 for the disk).
