Sven:
I believe that what I suggested was to have a warning period
before the change is actually introduced. In this case it would
mean to get the warnings into 1.7.5, and then some months later
(1.7.6?) make the actual syntax change.
In general that is good procedure, I agree. On the other hand, in
this case the "||" and "&&" forms for OR and AND (and only
those)
have been in the manual for over a year, and none of the sample
scripts packaged with gretl use the old forms.
I did find one of the separately-packaged Stock/Watson scripts
that used '&' for AND; I've now replaced that.
Allin.
