🚀 go-pugleaf

	Here is a patch for the Xaw3d library (0.6A) for X11R5 to get it to
work on X11R4 also.  This is an unofficial patch, provided in case there
are people with R4 servers and libraries out there that want the latest 
version of this library.  Patches were made using the latest available 
version for R4, Xaw3d 0.4, and borrowing some R5 library source code.  Apply
this patch in the Xaw3d directory with "patch -p < thisfile".  If make has
trouble with the Imake-produced Makefile, you can just as easily compile
everything with "xcc -DX11R4 -DARROW_SCROLLBAR -I. -c *.c", where xcc is
the compiler and the cflags you normally use to compile X programs.

	Usage of the patched library and header files is as normal except
when you are using the Xaw3d header files you need to define X11R4.
I tested this on the O'Reilly Xaw examples distributed with X11R4, 
and with aXe 4.0 compiled to use 3d Athena.  The Xaw examples all work fine,
and so does aXe except for an occasional screen update problem.  This may
be an aXe problem with the way it uses Xaw3d, however, because the O'Reilly
examples do not show that kind of behavior.

	Again, this is an unofficial patch with all standard disclaimers
attached, merely provided for your convenience.  If you have any 
questions/comments, e-mail me at jake@aspen.njit.edu.
