There are several servers (well, at least two) geographically
distributed. One may be lagging behind and not have the file yet.
(Just a guess.)
You can try http://pause.perl.org/incoming/ for very recently uploaded
items or http://backpan.perl.org/authors/id/T/TI/TIMB/ (often lags).

It means you don't define it yourself. That's fine, it's what I'd expect.

Yes.

No, it's just the PL_ change I believe. I've appended the change applied
to the DBI (from a patch by Andreas Koenig).

Er, I'm not sure.
Another approach to the issue is to run Devel::PPPort on your code
http://search.cpan.org/perldoc?Devel::PPPort
E.g.
perl ppport.h Informix.xs
That'll tell you what need changing.
Tim.
p.s. Another approach is to build perl 5.13.4+ and then build DBI and
drivers using that and see what breaks.
