I'm not sure I like this, because it means it would be impossible to implement
TS-1882 ("ATS doesn't warn about unknown config items").
What I would like is one of
1) Set the defaults to 0 consistently, as it was.
2) Make the entries in records.config.default.in also conditional (I don't know
if this is possible).
#2 still has the problem that it could generate errors later on when someone
switches ATS build or configs, but that's probably OK.
Also, the new text in records.config is *much* too verbose IMO. Attached is a
proposed new format. This also includes what I think is a bug fix, the debug
config restricts to values 0 or 1, but there are two bit fields, so it should
be at least 0-3.
Cheers,
