This bug was fixed by patch 1 for MCL 2.0. Patches 1 and 2 are available
for anonymous FTP from cambridge.apple.com in the directory
"/pub/mcl2/patches/". You can get them via mail by sending a message
to firstname.lastname@example.org (send a message with a single
line: "help" to find out how to use the archive server).
While investigating this, I found another bug in MCL's byte file I/O.
STREAM-EOFP does not work correctly on streams with other than 8 bits
per element. I have prepared a patch for inclusion in patch 3 for
MCL 2.0. If you want it before then, ask for "stream-eofp-patch".
