[movitz-cvs] CVS update: movitz/losp/muerte/more-macros.lisp

[Frode Vatvedt Fjeld]

Update of /project/movitz/cvsroot/movitz/losp/muerte
In directory common-lisp.net:/tmp/cvs-serv23725

Modified Files:
	more-macros.lisp 
Log Message:
Changed the low-level formatting of bignums: Now the number of bigits
is stored as factors of 4. This restricts the number of bigits to
(1- (expt 2 14)), which is still plenty.
