More AMD breakage coming up. As Diapolo hinted earlier, there is a new AMD driver 12.2 with an SDK that claims to be sdk 2.6 but comes up with the version number 898.1. It breaks cgminer completely making it unable to build any binaries.

I have yet to investigate why but please do not upgrade unless you already have .bin files that work. I'm going to start a collection of bin files that people may be able to download and they'll be housed here:
http://ck.kolivas.org/apps/cgminer/bins/Notably there are Tahiti (7970) .bins for 32 bit (long4) and 64 bit (long8) as these depend on sdk2.6 and people may well get a nasty surprise if they try to get it working now with the latest drivers.
