Hi Kamil,
That particular commit does actually depend on the previous commit. But to
fix your particular problem, you should only need the below change (which
doesn't have dependencies):
--- a/statement.c

Alternatively, just build with the latest code from the master branch.
I'm not part of the psqlODBC team so I'm not aware of the release schedule.
But whenever a new version is released, a message is posted on this mailing
list, so just stay subscribed.
