Well, wouldn't you know it, a quick symlink from ~/.netscape/ifc11.jar to
/usr/local/netscape/java/classes/ifc11.jar and now Netscape 4.0beta3's a
happy camper, even w.r.t. Java.  (Although I noticed that it runs the Java
apps noticably slower than 3.01, slow even for an SPARCstation 20/71.)

Much thanks to John for his suggestion.  I'm glad to have this working,
even if it takes a couple of symlink kludges that I don't think should need
to be there ...

Anyway, Executive Summary: 4.0beta3 (SunOS binary) works on my 1.2.1 box iff

	(a) I use the SunOS 4.1.3_U1 libc/libdl/ld.so in /emul/sunos/usr/lib
	(b) ~/.netscape/java40.jar exists and is a symlink to
	    /usr/local/netscape/java/classes/java40.jar
	(c) ~/.netscape/ifc11.jar exists and is a symlink to
	    /usr/local/netscape/java/classes/ifc11.jar

Hope this helps somebody,

	- Greg
