You are right -- I have verified on another machine and it is clearly
the 2003-12 snapshot that introduces this problem, while 2003-11 works
just fine.

Thanks. I didn't know about the entry in parms.lisp. After adjusting it
everything went relatively smoothly. That's the first time I've built
CMUCL, so I didn't know what to expect. Just for the reference, I had
to:
-- do a cross-compile (a normal build would not work and I didn't
investigate),
-- remove package locks during the build process, as it otherwise
wouldn't continue,
-- ignore the fact that PCL did not get built during the
cross-compile, and rebuild the target with itself adding (pushnew
:pcl *features) to xtarget/setenv.lisp to get PCL,
Otherwise, things went fine. Oh, motifd didn't build (it seems it was
missing libpthread and some other X libraries), but I really don't care
about that, so I didn't investigate.
So, I have a working CMUCL again! And your (Ole) PCL patch fixes the "NIL
fell through ETYPECASE" error nicely.
Many thanks to all of you.
