Yes, there are several areas the driver does not support.  However, I have been in the
middle of *EXTENSIVE* additions to the driver.  These include,  Multi row-wise and
column-wise binding support (instead of just 1 column-wise binding), with extensive work on
SQLExtendedFetch.  This is one area that was erroring out in the log you sent me.  I am
also redoing the way options are set and retrieved for SQLSetStmtOption and
SQLSetConnectOption.  This should help you out also.

I felt the same way at first.  But it is useful, because even in Windows, applications were
writing all over each other's log files.  If you sort by date in Explorer and do a refresh
before you look at the log files, the latest one will be right at the top of the list.  I
don't know if that is useful to you or not.
