    Loading VECTOR into a XCOMPLR loses when a putprop is attempted on a 
    fixnum while loading the new winning EXTEND. I renamed LISP;EXTEND FASL
    to LISP;EXTEND LOSER and the linked LISP;EXTEND FASL to OFASL.

Actually, the problem was that the current dumped COMPLR has some out-of-date 
files already loaded in it (losing EXTSTR was the offender in this case). 
I've re-installed the new EXTEND, and put up a COMPLR fix file (which also 
loads in the new DEFMACRO file, having the features you requested a few weeks 
ago regarding &aux etc.)
