I've been trying to install RCS (Rochester Connectionist Simulator)
on a Sony NEWS workstation (BSD 4.3, X11R3); however, there seems
to be an X11 include file missing from my system. The distribution
for version 4.2 pl0 for RCS expects the existence of the include
file /usr/include/X11/VPanedP.h which is missing from my system and
also is not part of the MIT X11R4 distribution. The include file
VPaned.h (which does exist) states that it is obsolete due to the
inclusion of Paned.h -- since there is also a PanedP.h, I attempted
to substitute that for VPanedP.h, which enabled me to finish compiling
the simulator. All portions/examples of the simulator which do not
require the graphical interface module(s) work fine; however, if I try
to start one of the examples which use the X11 interface, I get an error
stating that a widget has been defined with 'either zero width or
height'.

So, I have two questions -- what is this VPanedP.h include file and why 
is it not in either my X11R3 system or the MIT X11R4 dist? -- and, how
can I either find this include file or find a patch so that I can use
the newer PanedP.h file?

Since I ftp'd my copy of RCS 4.2pl0 directly from Rochester last week, I
doubt that there is a more recent version (4.2 seems to be late 1989);
but if there *is* a more recent version - particularly for X11R4 - I
would greatly appreciate being told where to find it.

Please email suggestions/hints/ideas/solutions to me and I will post a
'fix-it' guide (if I ever get it 'fixed').


Thanks,
