#50 4.0.2 Class Accept Vistor Problem

[Jerry Goodnough]

In Version 4.0.2 the way that the Subclass and
Superclass lists are maintained was altered to prevent a
problem with very long class names. When the new
mechanism was put in place a Coding error was made
in the implementation of
ESI$Class.Primary::AcceptVisitor, which resulted in it
skipping sublclasses. This error results in various
breakages, like Sreach not scanning subclasses when
requesed.

Warning

This patch should only be installed to 4.0.2 systems

This patch is has built in protect to prevent loads on any
version other than 4.0.2.8.
