It suppresses a warning that is treated like an error by compiler flags. I did not want to go deeper into fixing the code I'm not familiar with. I'm also not feeling great about ignoring a compiler warning, but since its not our product, as long as it works - should be ok, I think?

Not sure, I believe we will know once we run the tests against kolme. :-)
