I found the source of the problem.
I'm using the CVS version. options.c, line 73, has the following:
else if (ci->updatable_cursors)
setval = SQL_CONCUR_ROWVER;
In other words, if updateable cursors are at all available, they will override
whatever I choose to use for concurrency settings.
Commenting out these two lines solve the problem for me. I can also disable
"Updateable cursors" in the ODBC settings, but that would mean that no cursor on
the database can be updateable at all, and that's not acceptable.
