I tried this out with the canonical diamond class, and it did work in
all the cases I tried (gcc 2.95.2, gdb cvs 2001-03-17, red hat linux
native, stabs).

I spent some time looking at gdb with virtfunc.cc.  gdb is coming up
with a bizarre offset: it thinks the offset of the "A" object in class
"E" is 28, when it should be 0.  That's causing most (if not all) of
the problems.

Maybe this can be fixed without breaking something else.  I'm going
to investigate more.
