maxima 5.14.0

["Chavdar Ivanov" <ci4ic4%gmail.com@localhost>]

Hi,

I noticed maxima has been updated to 5.14.0. It would be nice if,
perhaps using the options framework, one could choose SBCL in place of
CLISP. It seems SBCL is substantially faster than CLISP, although this
probably is due to higher memory footprint (which one could argue is
not as important these days...).

Xmaxima 'Run Tests' results:

using just:

cpu0: Intel Pentium III (686-class), 797.52 MHz, id 0x683
cpu1: Intel Pentium III (686-class), 797.53 MHz, id 0x683

(so the speedup on this relatively slow box is valuable).


There are differences in the package sizes:

The following (obvious) patch would allow building it on the platforms
which support SBCL:
