Cristophe correctly diagnosed the problem, which was that the DEFKNOWN
return type of READ-DELIMITED-LIST in fndb.lisp was declared to be T,
when it should be list. This fixes the problem, and the resulting
SBCL compiles sans difficulty.
I've attached the patch, which I hope will be of some use; however,
it's against the local CVS SBCL tree I'm trying to set up, so my
general CVS cluelessness may have many an SBCL maintainer going for
hair as if it were rainforest. I'm using 0.7.12 at present and I
apologize if this makes it harder to apply the patch.
