Summary: TIME(%) always yields 0.0

Initial Comment:
TIME(%) always yields 0.0.

The cause is that TIME (suprv1.lisp) returns the value
of LASTTIME when the TIME argument is %.  However
LASTTIME is assigned 0 and never assigned anything
else; LASTTIME appears to be obsolete, and it is unused
except for this reference in TIME.

TIME uses the 'TIME property of output labels to fetch
the computation time.  % isn't assigned the 'TIME
property, so presumably that's why TIME was asking for
LASTTIME.

Let's not resurrect LASTTIME.  Instead let's (1) assign
% the 'TIME property (search for "putprop d-tag" in
macsys.lisp) to find the place to do it); and (2) cut
out the special case for % in TIME.

Message:
The suggested change to store the computation time in the symbol '$% has
been checked out (rev. 1.74, macsys.lisp). The variable $lasttime has been
cut out (rev. 1.80, suprv1.lisp).

Closing this bug report as fixed.
