Unable to compile Cinco de Mayo PCL in Medley

[ralph@nastassia.laas.fr]

Under Medley on a Xerox 1186, the new PCL balks in the file boot.lisp.
It gives a "BUG: Inconsistent stack depths seen." under EARLY-DFUN.  I
am using the "19-Sep-88 17:45:52" sysout of Medley -- not the new
Medley 1.1.
		  
This may be either a tail-recursion problem (it occurs under the FLET)
or a Medley bug.  I am not used to the compiler stack traces, but
the code/stack frames just above the call to STACK-ANALYSE are:
EARLY-DFUN, SORT-METHODS, and "lambda in SORT-METHODS".

Has anyone else encountered this problem and does there exist a patch?
I hope that the description was informative enough.
