Hello Yasuaki,

I have committed the patch to src/clmacs.lisp.
run_testsuite doesn't report any new errors with
clisp 2.34, sbcl 0.9.4, and gcl 2.6.7 on linux.
Since you are clearly a careful and competent programmer,
I would like to ask you to become a Maxima developer
so that in the future you can commit patches directly to cvs.
If you wish to do so, please make a login at SourceForge
(if you do not already have one) and email it to me.
Thanks for your contribution to Maxima,
Robert Dodier
