For fun, I tried chipz with maxima. Just hacked maxima defsystem to add 
a chipz module. It builds fine with the lisps I have configured and 
basically works. Except with gcl where I get the error:

|(%i1) :lisp (with-open-file (gz "set-float.lisp.gz" :element-type 
'(unsigned-byte 8)) (with-open-file (s "output2" :direction :output 
:if-exists :supersede :element-type '(unsigned-byte 8)) 
(chipz:decompress s 'chipz:gzip gz))) Error: Fast links are on: do 
(si::use-fast-links nil) for debugging Signalled by PROGN. Condition in 
PROGN [or a callee]: INTERNAL-SIMPLE-PROGRAM-ERROR: PROGN [or a callee] 
requires less than one hundred thirty-four arguments. Broken at 
CHIPZ:DECOMPRESS. Type :H for Help. 1 Maxima top-level 2 Return to top 
level. |

I don’t know enough about gcl’s debugger to figure out why there are 134 
(or more?) arguments. |chipz:decompress| itself only has 3 args. I 
didn’t dig any further though.
