Just a simple query for all the knowledgeable folks:

Is there a "portable" CLOS that can be used with CMUCL?

It appears that CMU's CLOS is held up for testing, and I have no information on how 
portable the generated code would be.

Any help is greatly appreciated.

CMU CL is currently distributed with a suitably modified version of PCL.

We have plans and some design ideas for a native CLOS, but we aren't
really even coding, let alone testing.  By the end of this summer, we
should have a version of the latest PCL that is more integrated with
our system (better object representations, compiler support, etc.)

I'm not sure what you mean about how portable the generated code would
be.  The answer is probably "not very", but then you wouldn't care
unless you were trying to take CMU's CLOS and adapt it to another Lisp
implementation --- uses of the CLOS operations would remain portable.
