clisp vs. SBCL

Hi,

If one wants to use xMaxima for some maths, it is strongly advisable
to make sure it is using SBCL, as opposed to the default clisp. Here
are the results of the tests performed on the same machine, same
version of xMaxima, first with clisp, then with SBCL:
.....

xMaxima test, clisp
