Ok, Thanks again, Allin.
I found the problem. I didn't see it at first because it's
specific to annual data and I was testing on quarterly data.
Anyway, thanks for the report and this should now be fixed in CVS
and snapshots.
(The problem: the ADF test in the gretl GUI, with annual data, (a)
showed the quadratic trend option as disabled, but (b) in fact
included this test option regardless of what was selected.)
