[Ecls-list] ecl-10.4.1 doesn't compile maxima-5.20.1

[Andrey G. Grozin]

I get:

Making all in src

`/var/tmp/portage/sci-mathematics/maxima-5.20.1-r1/work/maxima-5.20.1/src'

Previous versions of ecl could compile maxima (though 10.3.1 produced an 
unusable result :-( )

By the way, ecl.info and ecldev.info disappeared from 10.4.1. Is this on 
purpose?
