xlispstat2.1R2 incorporates some bug fixes and minor modifications.
The changed files are listed below. Patches for working around bugs
in the ULTRIX 4.0 servers and libraries have been incorporated, so
the separate ultrix patch is no longer needed.

Makefile		modified to no longer use ld -r (which ceased to work
			properly with shared libraries on SunOS 4.1 and never
			worked on the Cray XMP).

README.2.1R2		This file

RELEASE			Minor fixes and spelling corrections

StX11options.h		Added define for working around ULTRIX XDrawPoints bug

X11dialogs.c		Added XSync all to StX11DialogReset to drop pending
			X events on an error reset

X11graph.c		Added code for working around ULTRIX bugs

X11listitem.c		Fixed bug in :set-text method for 2D lists

X11scroll.c		removed pointer grab to avoid freezing the screen if
			the method goes into an infinite loop or the server
			gets confused on queue overflow (may be a problem in
			Sun's xnews server)

X11slider.c		removed pointer grab to avoid freezing the screen if
			the method goes into an infinite loop or the server
			gets confused on queue overflow (may be a problem in
			Sun's xnews server)

X11text.c		Fixed bugs that could result in overestimate of text
			field width

commonmath.c		Fixed rem function to match CL definition for neg. args
			Added mod function (same as old version of rem)
			Modified integer arithmetic to (hopefully) overflow to
			floating point when necessary. This probably needs
			more work but should do for now. If it does not work
			on some systems you can define a preprocessor variable
			to revert to the previous handling of integer 
			arithmetic.

compound.c		fixed bug of intermediate results in arithmetic with
			matrices or objects not being protected from GC

linalg.c		fixed bug of result of chol-decomp not being
			protected from GC

math.c			added mod function

osdefs.h		added mod function

osptrs.h		added mod function

postscript.c		added BoundingBox comment to output (for psfig)

version.h		updated to reflect new release

xlisp.help		fixed incorrect argument info for list item :set-text
			added mod help info

xlisp.help.small	added to the distribution

macintosh/macdialogs2.c	fixed bug that could cause overestimate of text field
			width

machines/decstation	added directory

machines/decstation/README	added pointer to pmax directory (not everyone
				is in on the pmax terminology!)

machines/pmax/README		added description of ULTRIX 4.0 X bug
				workarounds

machines/pmax/StX11options.h	set up for use with ULTRIX 4.0/dxwm

machines/sun3/README		modified to reflect changes in Makefile
				added info for use with openwin

machines/sun4/README		modified to reflect changes in Makefile
				added info for use with openwin
