BUGS.
	There is a nasty bug in XView 2.0 which causes XView to core dump
when run xrolo is run in 2D mode (the default on B&W displays). If you
are linking xrolo against a library that was created from the XView
sources available at expo.lcs.mit.edu, apply the following patch and
recompile libolgx. Sun claims that this bug will be fixed in OW 3.0.

if you are linking agains the XView libraries that come w/ open look
then:
	1) obtain a copy of ol_button.c from one of the source archives. 
	2) apply the patch.
	3) cd $OPENWINHOME/lib
	   cp libolgx.a libolgx.orig
       ar rlv libolgx.a ol_button.o  
	4) link xrolo using the following sequence
	cc -o xrolo -O -L$OPENWINHOME/lib -lxview -Bstatic -lolgx -Bdynamic -lX11
