Really great news!  So we can depend on the CL package containing all
of the expected symbols?

Will it also signal exceptions better?  I vaguely remember some maxima
code that has special cases for gcl because gcl wasn't signaling
arithmetic exceptions in the expected way that other lisps were doing.
(That's really vague. If you do expect exceptions to work better, I'll
try to find the specific instances.)
