My previous SLIME installation was a CVS install from 4/18. I've just taken the latest CVS install and the ACL SLIME implementation (under Windows) breaks. Here is the error:

EXCL::DEFUN-PROTO-1 is not a function or macro [Condition of type SIMPLE-ERROR]

Restarts: 0: [ABORT] Return to sldb level 1. 1: [ABORT] Abort handling SLIME request. 2: [ABORT] Abort entirely from this process.
