Hi Greg, Thanks very much for all your work on this, and Barney Stratford too. This is great news. I'm doing a lot of numerical work with Doubles at the moment, so progress is quite welcome!
I can try building 7.0.1-RC using a 32-bit 6.12.3, although probably not until the weekend. I'll let you know how it goes. If there are any special build instructions for this, maybe you could update trac #2965 with details?
