build_info fails in ECL + Maxima (unbound *MAXIMA-BUILD-TIME*)



Hello,

I am trying Maxima 5.16.1 compiled by ECL.
The only problem I know about at present is this:

(%i1) build_info();

Maxima version: 5.16.1
Maxima encountered a Lisp error:

 The variable COMMON-LISP-USER::*MAXIMA-BUILD-TIME* is unbound.

*MAXIMA-BUILD-TIME* is defined in src/maxima.asd.
I don't know how build_info (which is in src/macsys.lisp or something like that)
is supposed to get it. Does someone know ?

Thanks for your help,

Robert Dodier
