While this patch does what it says, it doesn't mention the fact that all 
versions of BIND for the foreseeable future are going to have this 
additional field (it's in all currently supported versions of BIND), so 
you will be MUCH better off fixing the software that is ingesting the 
log file than to patch BIND every time you upgrade.
