Worse, cssdiff is unaware of it's shortcomings, and will try anyway. The only recourse is to be aware of this issue and not use cssdiff on Winnow classifier floating point .cow format files. http://crm114.sourceforge.net/ This manpage: $Id: cssdiff.azm,v 1.5 2004/08/19 09:06:44 vanbaal Exp $ This manpage describes cssdiff as shipped with crm114 version 20040816.BlameClockworkOrange.
