Buggy XLISP

[JONL at MIT-MC (Jon L White)]

Incidentally, since last Saturday, the "newer" lisp had been placed as
LISP^K, so XLISP^K is again experimental.

	    LISP;EXTEND fails to load into an XL, dying trying to call 0 
    (actually its when EXTSFA is being loaded). Congratulations, that's 
    every day now for the past two weeks that some piece of the system has 
    screwed me.
LISP^K and XLISP^K, although same version numbers, should have been different 
dumps when you got this problem, and you shouldn't have seen it in LISP^K. 
RWK's fix is correct, mentioned in

    The problem with EXTEND and EXTSFA and YESNOP not loading is due to
    GENTEMP not working which is in turn due to EXPLODEN being broken, giving
    FXPDL OUT OF PHASE for fixnums, and ILOPR at location 0 for flonums.

    I have fixed and patched the problem.
However this patch should be installed only as XLISP^K, due to the
fact that I was still trying to get the bug out of PUTPROP referenced as

    Sigh, remember the PUTPROP twice bug that has plagued us lo these
    6 years?  This is still another manifestation of it.  I've done some
    more work on PUTPROP, but it still isn't completely bug-free .  .  .
So I hope this "experimental" PUTPROP doesn't cause any problems -- 
they would be manifest when pure-loading up a big system (like,
COMPLR, NILAID or MACSYMA!)
