Virtual base class in CINT

	I'm trying to generate a CINT file for some classes of mine and
have run into some difficulty. I have a class called MCDiag which
inherits from a pure virtual class, EventSource. The problem is that
CINT seems to be refusing to generate Streamer() and ShowMembers()
methods for my MCDiag class. I looked around the web site and saw that
by adding certain characters into the LinkDef file one could stop these
methods from being generated. I'm sure I don't have those flags set in
the LinkDef file. I just can't figure out why CINT won't generate the
Streamer() and ShowMembers() methods. Here is what happens when I call
rootcint:

V:\LCD\RootApps\Utils\prod\src>rootcint -f UtilsCint.cxx -c
-I..\..\..\Event\pro
d\src -Iv:\lcd\lcd-working\StdHep\src\inc EventSource.h readStdFile.h
MCDiag.h UtilsLinkDef.h
Note: operator new() masked 1c
Note: operator delete() masked 1c
Class MCDiag: Streamer() not declared
Class MCDiag: ShowMembers() not declared

V:\LCD\RootApps\Utils\prod\src>

	The odd thing is that the class readStdFile also inherits from
the virtual base class EventSource and seems to get all of it's methods
generated just fine.

	Suggestions?
