New defsystem 3.6i (Was Re: OpenMCL support Re: [Maxima] Installation of maxima-5.9.2 on Mac OS X)

Hi all,

Let me summarize the situation:

defsystem 3.6i
OK: clisp 2.38, openmcl 0.14.3, sbcl 0.9.7, cmucl 19c, gcl 2.6.7
Not confirmed: SCL (some work under its way)

Current defsystem
OK: clisp 2.38, sbcl 0.9.7, cmucl 19c, gcl 2.6.7, SCL (Am I correct?)
NG: openmcl 0.14.3

Let me add few words on openmcl support situation. With defsystem 3.6i
and recent patches I committed to CVS tree, openmcl certainly compiles
the maxima 5.9.3 branch, and it works. However, I still see some tests
do fail. Failed tests are unfortunately not limited to trig related.
This means it is a bit early to say that OpenMCL is fully supported by
Maxima.

If SCL has been a supported platform till today and we keep its
support level as other platforms, I would recommend to stay with
current defsystem for 5.9.3. Note that we would only obtain the
openmcl incomplete support by switching the defsystem to 3.6i,
seeing the above summary. Thus, the switch to 3.6i really does
not reduce any maintenance cost of maxima.
