Well....
it works, sort of.

We are using informixdb in a production environment with several
informix server versions (7.xx, 9.xx) on HP-UX, Solaris and Linux
for 2-3 years now.
I had to fiddle around with S. Turner's code to get stored procedures to work,
and Date/Time fields were an issue.
For me, the most difficult work was to compile the whole thing. Still no
luck in producing a thread-safe version of _informixdb.so which is
needed for zope.
Turner's code has a surprisingly small footprint and works very well,
I have just finished a script that does about 15000 queries, each of them
returning one row of data. Time needed to execute about 2 minutes.
My knowledge of esql/c is too limited so I cannot help much in
improvement and/or further development.

best regards,
Rüdiger
