Maxima's current defsystem doesn't work with the latest CMUCL snapshot
because the :cmu18 feature is gone (it's :cmu19 now).
I would like to fix this by basically taking the :cmu feature to mean
cmu17 and later. This allows current CMUCL to work, but CMUCL older
than version 17 won't work anymore. I think it's pretty safe
assumption that no one is such an old CMUCL.
Alternatively, the defsystem from CLOCC works with this CMUCL snapshot
but there are quite a few differences between that version and
maxima's. I don't really want to just import the CLOCC version
completely, since I haven't been able to test maxima with anything
other than CMUCL in a long time. In particular there are gcl specific
changes, and I haven't tried gcl in ages.
Opinions?
