"Also found
initialization in ifdef that caused some problems with error
messages in occasions when the wrong syntax was used."

To be more accurate it's just variable initialization that was in wrong
place.
Moreover in most cases (almost always) after allocating memory for this
variable there was non-zero value ('true', basically), that was causing
"keyword 'BEGIN' is reserved" error message if we use "BEGIN" instead
of "START TRANSACTION", after the patch changes are applied.
