Re: [Gretl-devel] strange warning, Johansen test with restricted vars

The intent (and I think the actuality) is that that warning is printed only when the user has selected the "unrestricted constant" case. But since that case is statistically weird we drop back to the "closest" less-weird case, namely the restricted trend (as does CATS, I believe). The assumption is that the "exo I(1)" variables in question are something other than constant or trend.
