Possible problem compiling from the latest HEAD!

I just downloaded the latest HEAD. When I compile in the release mode I get the following warning errors:

It compiled fine (other than these warnings) and everything seems to run OK.
I did not have any of these errors when compiling previous versions.
I am using DX9 and have been for a few months and have not had any problems. I was just wondering if the patch for DX9 "TGE Patch: DX9 Support" has been applied in this latest release and if so I wonder if this could be causing the problem. I looked at the "Change List" and could not find anything pretaining to DX so I am not sure.

Thanks
